Abstract
OBJECTIVE This study aimed to systematically review and quantitatively synthesize the existing evidence to better identify the high-risk population of hepatocellular carcinoma (HCC) in nonalcoholic fatty liver disease (NAFLD). MATERIALS AND METHODS We searched databases including MEDLINE, EMBASE, Web of Science, Cochrane Library, and ClinicalTrials.gov up to February 2023. The meta-analysis was performed using RevMan5.3 software, and we calculated the estimated combined effect using inverse variance weighting of OR. I2 statistics were used to quantify the inter-study heterogeneity. Funnel plots and Egger test were used to assess publication bias, and sensitivity analysis was carried out through the transformation effect model or the removal of literature one by one. RESULTS Finally, 29 articles were included in the study, which involved a total of 726,656 patients with NAFLD. A total of 15 major risk factors were evaluated. Statistically significant risk factors were: advanced liver fibrosis (OR=6.40), diabetes (OR=2.38), obesity (OR=1.46), hypertension (OR=1.75), older age (OR=3.57), male (OR=2.45), alcohol intake (OR=2.98), smoking (OR=1.44), PNPLA3 genotype variation (OR=1.76), elevated liver enzymes (OR=2.92), low platelet counts (OR=4.61), and low albumin levels (OR=2.11). CONCLUSIONS Our results showed that advanced liver fibrosis, diabetes, obesity, hypertension, older age, male, alcohol intake, smoking, PNPLA3 genotype variation, elevated liver enzymes, low platelet counts, and low albumin levels were all significant risk factors for HCC in NAFLD. However, dyslipidemia was not found to be a risk factor. Further exploration is needed to confirm whether Hispanic ethnicity and high ferritin levels are also risk factors.

Abstract
Ferroptosis is a novel mechanism of programmed cell death characterized by an iron overload-induced lipid peroxidation cascade. The incidence of alcoholic liver disease (ALD) is rising globally, contributing to markedly high morbidity and mortality. ALD pathogenesis is an intricate and continuously evolving process. Several basic and clinical investigations have established a correlation between ferroptosis and ALD initiation and progression. Additionally, anti-ferroptosis drugs have demonstrated effectiveness in ameliorating alcohol-induced liver injury. This review aims to provide an overview of recent advancements in ferroptosis research pertaining to ALD, encompassing imbalance of antioxidant systems, iron overload, autophagy, mitochondria, epigenetic changes, and prospective therapeutic drugs targeting ferroptosis. Our aim is to reveal the potential of ferroptosis-related diagnoses and therapeutic interventions for the treatment of ALD.

Abstract
OBJECTIVE Immune checkpoint inhibitors have initiated a new era in hepatocellular carcinoma (HCC) treatment. For improving the prognosis of patients with resectable HCC and reducing postoperative recurrence, immunotherapy is being developed in the neoadjuvant setting. However, the efficacy and safety of neoadjuvant immunotherapy remain unclear. MATERIALS AND METHODS PubMed, Embase, Medline, and Cochrane Library databases were systematically searched for the clinical trials of neoadjuvant immunotherapy for resectable HCC. A single-arm meta-analysis was conducted to calculate the odds ratio and 95% confidence interval (CI), and statistical transformation was performed to obtain the pooled rate P(t) and its CI. Subgroup analyses were performed according to the type of combination therapy. RESULTS 81 patients from four studies were included in this meta-analysis. In patients with resectable HCC, the pooled major pathological response (MPR) rate and pathological complete response (pCR) rate for neoadjuvant immunotherapy were 0.23 (95% CI, 0.14-0.36) and 0.19 (95% CI, 0.10-0.30), respectively. The pooled objective response rate (ORR) was 0.18 (95% CI, 0.10-0.28), comparable to the results of immunotherapy for advanced HCC. The overall treatment-related adverse events (TRAE) rate was 0.80 (95% CI, 0.68-0.89), but the grade ≥3 TRAE rate was low at 0.21 (95% CI, 0.13-0.33). The pooled surgical resection rate and surgical delay rate were 0.95 (95% CI, 0.85-0.98) and 0.05 (95% CI, 0.02-0.16), respectively. Subgroup analyses revealed no significant differences in clinical outcomes between immunotherapy combinations. CONCLUSIONS This meta-analysis provides preliminary evidence of the efficacy and safety of neoadjuvant immunotherapy for HCC, suggesting that it is a promising perioperative treatment option. Conclusive evidence supporting its use requires additional data from large-scale clinical trials.

Abstract
We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Abstract
OBJECTIVE Liver neoplasm is one of the most fatal malignancies worldwide, among which hepatocellular carcinoma (HCC) (MIM #114550, https://omim.org/) is the most prevalent type. ABCC1 (MIM *158343) is a membrane-bound protein that relies on ATP hydrolysis to transport substrates and is associated with tumour drug resistance and malignant potential. However, the relationship between ABCC1, HCC prognosis, and immune infiltration remains elusive. MATERIALS AND METHODS We analysed the mRNA expression of ABCC1 using data from public databases. Immunohistochemistry staining was performed to identify ABCC1 expression in tumour samples. We further investigated the correlation between ABCC1 and clinicopathological features. We investigated the connection between ABCC1 and HCC prognosis using survival and Cox regression analyses. We investigated the underlying pathways of ABCC1 in HCC using functional enrichment analysis and GSEA. We determine the relationship between ABCC1 and immune cell infiltration via an integrated immune landscape analysis. RESULTS Our investigation revealed the upregulation of ABCC1 expression in HCC (p < 0.01), which was verified in clinical samples (p < 0.01). In addition, ABCC1 is adversely associated with HCC clinical features and prognosis (p < 0.05). GO/KEGG analysis and GSEA identified that ABCC1 participates in multiple immune- and tumour-related pathways (p < 0.05). Immune cell infiltration analysis indicated that ABCC1 was positively correlated with various immune cells, among which, the strongest correlation was with macrophages (p < 0.001). Furthermore, we observed significant variations in immune checkpoints between the ABCC1-low and ABCC1-high groups (p < 0.01). This indicated that patients with a high expression of ABCC1 might respond poorly to immune checkpoint blockade (ICB) therapy (p = 9.2e-07). CONCLUSIONS Our study identified ABCC1 as a predictor of HCC prognosis and response to therapy.

Abstract
Objectives: To evaluate the role of pancreas multidisciplinary team(MDT) clinic in the diagnosis of pancreatic diseases,patient compliance with MDT advice,and the impact of MDT on the postoperative survival of patients with pancreatic cancer. Methods: The study included 927 patients(554 males,373 females,aged (58.1±13.3)years (range: 15 to 89 years)) that had visited the pancreas MDT clinic of Zhongshan Hospital from May 2015 to December 2021,and 677 patients(396 males, 281 females, aged (63.6±8.9)years(range: 32 to 95 years)) who underwent radical surgery and with pathologically confirmed pancreatic adenocarcinoma from January 2012 to December 2020,of whom 79 patients had attended the pancreas MDT. The clinical and pathological data were collected and analyzed retrospectively. Diseases were classified in accordance with 2010 WHO classification of tumors of the digestive system and usual clinical practices. The Kaplan-Meier method was used for drawing the survival curve and calculating the survival rate. The univariate analysis was done by Log-rank test and the multivariate analysis was done by COX proportional hazards model. Survival rates were compared using χ2 test. Results: Among the 927 patients that had visited the MDT clinic,233 patients(25.1%) were referred due to undetermined diagnosis. A direct diagnosis was made in 109 cases (46.8%,109/233) by the MDT clinic, of which 98 were consistent with the final diagnosis,resulting in an accuracy of 89.9%(98/109). The direct diagnosis rate in the recent years(36.6%(41/112),from June 2019 to December 2021) decreased compared to that in the previous years(56.2%(68/121),from May 2015 to May 2019),yet the accuracy in the recent years(90.2%,37/41) was basically the same as before (89.7%,61/68). The rate of compliance of the entire cohort was 71.5%(663/927), with the compliance rate in the recent two and a half years(81.4%,338/415) remarkably higher than that in the previous four years(63.4%,325/512). Patients with pancreatic cancer that attended the MDT exhibited a trend toward longer median postoperative survival than patients that did not attend the MDT,but the difference was not statistically significant(35.2 months vs.30.2 months,P>0.05). The 1-year and 3-year survival rates of patients that attended the MDT were significanly higher than patients that did not attend the MDT(88.6% vs. 78.4%,P<0.05;32.9% vs. 21.9%,P<0.05,respectively),but the 5-year survival rate was not statistically different(7.6% vs. 4.8%,P>0.05). Conclusions: The pancreas MDT clinic is an accurate and convenient way to diagnose intractable pancreatic diseases,and in the recent years the patients' compliance rate with MDT advice has increased. Pancreatic cancer patients that have attended the MDT have higher 1-year and 3-year postoperative survival rates,but the long-term survival benefits of MDT still needs to be proved by clinical studies on a larger scale.

Abstract
Critical ultrasonography is widely used in ICU and has become an indispensable tool for clinicians. However, besides operator-dependency of critical ultrasonography, lack of standardized training mainly result in the physicians' heterogenous ultrasonic skill. Therefore, standardized training as well as strict quality control plays the key role in the development of critical ultrasonography. We present this quality control standards to promote better development of critical ultrasonography.

Abstract
Although many studies have already described the physiological effects of bee products, such as honey, propolis, pollen, and royal jelly, on livestock farming, the health benefits of the honeycomb are still not fully understood. The problem of drug residues and bacterial resistance caused by the abuse of antibiotics is becoming increasingly serious. For this reason, a safe, green substitute has to be sought. We conducted a comparative study of honeycomb extract (HE) and an antibiotic on growth performance, carcass traits, immunity, antioxidant function and intestinal microorganisms of yellow bantam broilers. A total of four hundred eighty 21-day-old female yellow bantam broilers were randomly divided into 5 groups of 6 replicates of 16 birds each. The 5 groups were as follows, with birds receiving a basal diet supplemented with 150 ppm (mg/kg) of chlortetracycline (CTE), a basal diet without HE (control group), and a basal diet with 0.1%, 0.15%, or 0.2% HE for 60 days. The results showed that HE addition significantly increased average daily feed intake (ADFI), average daily gain (ADG), decrease feed gain ratio (F/G) from 21 to 80 and 51 to 80 days of age compared to the control group, with all 3 HE addition groups having statistically identical values to the antibiotic group. HE implementation dramatically increased spleen index, serum immunoglobulin A (IgA), immunoglobulin M (IgM,), glutathione peroxide (GSH-Px), superoxide dismutase (SOD), total antioxidant capacity (T-AOC), and total cecum bacteria and Lactobacillus compared to the control group, numerically at the same level as, or even better than, the antibiotic group. HE and CTE both markly reduced serum malondialdehyde (MDA) concentration compared to the control group, with higher concentrations of HE reducing the effect more dramatically than antibiotics. Both HE and CTE significantly raised dressed yield compared to the control group. In summary, HE, as a potential antibiotic alternative, improved growth performance, carcass traits, immune function, serum antioxidant capacity and intestinal microorganisms in yellow bantam broilers. According to the cubic regression analyses, the recommended supplemental dose of HE was calculated to be 0.15 to 0.17% for female yellow bantam broilers between 21 and 80 d of age.

Abstract
Objective: To explore the accuracy and efficiency of a novel 3D-printed emulation localization model of small pulmonary nodules in lung surgery. Methods: From April 2020 to April 2021, a total of 66 patients were selected in the study, who underwent localization and resection of pulmonary nodules with video-assisted thoracoscopic surgery (VATS) guided by the 3D-printed emulation localization model at Department of Thoracic Surgery, West China Hospital of Sichuan University. There were 13 males and 53 females, aged from 25 to 79 (52.7±11.4) years. Of all patients, 24 (36.4%) had single pulmonary nodule, and 42 (63.6%) had synchronous multiple pulmonary nodules. The chest high-resolution CT image data were utilized for digital reconstruction and 3D printing to make a tailored life-size emulation pulmonary nodules localization model, which was used to navigate real-time intraoperative localization of nodules. Clinical data including operative parameters, localization information, resection types and pathological findings of nodules were analyzed. The pulmonary nodules that doctors planned to resect were categorized into two categories:major nodules and additional nodules, according to their presence of invasion and radiological risk factors. The accuracy of localization and resection efficiency of nodules were evaluated in accordance with the categories of the nodules respectively. Results: On the basis of preoperative evaluation, there were 71 major nodules with median maximal diameter of 0.9 (0.6-1.3) cm, and 77 additional nodules with median maximal diameter of 0.5 (0.4-0.7) cm. All patients underwent VATS surgery, 52 of them (78.8%) were treated with uniportal VATS and 14 (21.2%) with triportal VATS. Among the patients with single nodule, 18 segmentectomies and 6 wedge resections were performed; whereas among the patients with multiple nodules, 5 segmentectomies, 14 wedge resections, and 23 combined pulmonary resections (including 2 cases of lobectomy+segmentectomy, 7 cases of lobectomy+wedge resections, and 14 cases of segmentectomy+wedge resections) were achieved. The median operative time was 93 (45-240) min, and the median resection time for all nodules was 51.4 (6.7-147.0) min. All major nodules were successfully resected and visibly dissected after removal, and all additional nodules were successfully resected with 85.7%(66/77) nodules visibly dissected. The accuracy rate of localization of both types of nodules was 100%. All major nodules were malignant, and the malignancy rate of additional nodules was 21.2%(14/66). Conclusion: This novel 3D-printed emulation localization model of small pulmonary nodules proved to be a non-invasive, accurate and efficient technique. Not only that, it has a unique advantage in localization of synchronous multiple pulmonary nodules.

Abstract
Objective: To investigate the effect and mechanism of periodontal ligament stem cell (PDLSC) from inflammatory environment on the secretion of interleukin-1β (IL-1β) by macrophages. Methods: PDLSCs were pretreated with lipopolysaccharide (LPS) in order to simulate the inflammatory environment. Human monocyte cell line (THP-1) cells were treated with conditioned media collected from healthy and inflammatory PDLSCs respectively and divided into conditioned medium of health PDLSC (CM-H) group and conditioned medium of LPS-PDLSC (CM-LPS) group. After 24 h of co-culture, the condition media were abandoned and THP-1 cells were then cultured for another 24 h. The expression of IL-1β in THP-1 cells supernatant was detected by enzyme-linked immunosorbent assay (ELISA). Quantitative real time-PCR (qRT-PCR) was used to detect the expression of glucose regulated protein 78 (GRP78), activating transcription factor-6 (ATF6), inositol requiring enzyme 1 (IRE1), protein kinase R-like endoplasmic reticulum kinase (PERK), CCAAT enhancer binding protein homologous protein (CHOP), activating transcription factor-4 (ATF4) and X box binding protein 1 spliced (XBP1s), which were all related with endoplasmic reticulum stress (ERS), in THP-1 cells. The expressions of proteins GRP78 and CHOP were detected by Western blotting. Furthermore, THP-1 cells, which pretreated with ER inhibitor 4-phenylbutyrate (4-PBA) for intervention experiments were grouped by various concentrations of 4-PBA including groups 0 (control group), 1, 10 and 20 mmol/L and treated with condition medium of inflammatory PDLSC. ELISA was used to detect IL-1β expression and qRT-PCR to detect expression of ERS related genes. Results: ELISA results showed that the expression of IL-1β in THP-1 cells of group CM-LPS [(31.35±2.11) ng/L] was significantly higher than group CM-H [(8.19±1.51) ng/L] (t=12.60, P<0.01). qRT-PCR results showed that the relative expressions of GRP78, ATF6, IRE1, PERK, CHOP, ATF4 and XBP1s genes in THP-1 cells of group CM-LPS (1.782±0.070, 1.387±0.204, 1.404±0.119, 1.777±0.187, 1.325±0.156, 1.295±0.066 and 1.137±0.149, respectively) were significantly higher than those in group CM-H (P<0.05). In the 4-PBA intervention experiment, compared with group 0 mmol/L, the expressions of GRP78, IRE-1, ATF-6, PERK and CHOP were significantly lower in group 1, 10 and 20 mmol/L (P<0.05). Moreover, compared with control group [(31.23±1.98) ng/L], the expression of IL-1β in THP-1 cells were significantly lower in group 10 mmol/L [(21.20±0.37) ng/L] and group 20 mmol/L [(23.85±1.80) ng/L] (P<0.05) with ERS inhibited. Conclusions: PDLSC from inflammatory environment could promote IL-1β secretion of macrophages through upregulating macrophages ERS.

Abstract
OBJECTIVE This study aimed to explore the significance of renal Doppler ultrasound in evaluating systemic and renal perfusion in sepsis patients before and after fluid resuscitation. PATIENTS AND METHODS Forty sepsis patients admitted to the Department of Intensive Medicine and intensive care unit (ICU) of the Fourth Hospital of Hebei Medical University from June 2014 to December 2014 were enrolled in this study, and 35 patients were included in the final analysis. These patients were divided into positive and negative fluid responsiveness groups. They were also divided into an acute kidney injury (AKI) group and a non-AKI group according to changes in creatinine and urine volume. The correlations of the changes in hemodynamics before and after fluid resuscitation in each group with the changes in renal resistance index (RRI) and renal blood flow (RBF) grades were evaluated. RESULTS Before and after fluid resuscitation, the heart rate (HR), blood creatinine (Cre), and lactate (Lac) levels of all patients, including the patients in the positive fluid responsiveness group decreased, and the stroke volume (SV) and central venous pressure (CVP) increased. Only HR decreased in the negative fluid responsiveness group. In the AKI group, HR, Cre, and Lac decreased, while in the non-AKI group, HR decreased, but CVP and SV increased. There were differences between HR, Lac, and change rate of Lac (Lac%) after fluid resuscitation for the positive and negative fluid responsiveness groups. There was no statistical difference between the RRI values of each group before and after fluid resuscitation. The RRI values of the AKI group were higher than those of the non-AKI group, while the AKI group's RBF grades were lower than those of the non-AKI group. The change rate of RRI (RRI%) was higher in the AKI group than in the non-AKI group. Except for the negative fluid responsiveness group, the RBF grade of each group increased. CONCLUSIONS The approach of RBF classification based on Doppler ultrasound can be used to evaluate the systemic and renal perfusion of patients with severe sepsis before and after fluid resuscitation, while the RRI value cannot be used for evaluation. However, the RRI value can be used as a dynamic index for the evaluation of renal perfusion in patients with AKI.

Abstract
Transesophageal echocardiography(TEE) is valuable in intensive care unit (ICU) because its application meets the requirements of diagnosis and treatment of critically ill patients.However, the current application has not fully adapted to the specialty of critical care. TEE could be more valuablein ICU when used with a new way that under the guidance of the theory of critical care and embedded into the treatment workflow. We have expanded and improved the application of traditional TEE and integrated the concept of critical care, established the concept of transesophageal echocardiography for critical care (TEECC). Chinese Critical Ultrasound Study Group (CCUSG) organized experts in the area to form the consensus based the previous studiesand the long term practice of critical care ultrasound and TEE, aiming at clarifying the nature and characteristics of TEECC, promoting the rational and standardized clinical application and the coming researches.The consensus of Chinese experts on clinical application of TEECC (2019) were 33 in total, of whichthe main items were as follows: (1) TEECC is a significant means, which is expanded and improved from the traditional transesophageal echocardiography according to characteristics of critically ill patients and is applied in ICU based on critically clinical scenarios and requirements by the critical care physician, to promote visualized, refined and precisely management of critically ill patients.(2) TEE possesses distinctive superiority in implementation in ICU. It has characteristics of images with good quality, operations with good stability and low-dependent of operators, monitoring with continuity, and visualization with all-dimensional and detail of heart and blood vessels.(3)As a means of refined monitoring that could resulted in precise diagnosis and treatment, TEECC expands the dimension of intensive monitoring and improves the performance of critical care. (4) Indications of TEECC application include clinical etiological searching and invasive procedures guiding when it acted as a traditional role; and also refined hemodynamic monitoring based on critical care rationale and over-all management under specific critical clinical scenarios. (5) TEE and TTE assessments are complementary; they are not alternative. Integrated assessment of TTE and TEE is required under many critical clinical scenarios.(6) TEE should be a necessary configuration in ICU. (7) All-round and significant information regarding to the mechanism of acute circulatory disorders can be provided by TEECC; it is a non-substitutable means of identifying the causes of shock under some special clinical scenarios. (8) Focal extracardiac hematoma can be accurately and rapidly detected by TEE in patients with open-thoracic cardiac surgery or severe chest trauma when highly suspected pericardial tamponade.(9) The priority of pathophysiologic mechanism of septic shock can be rapidly and accurately identified by TEE; even if its pathophysiological changes are complex, including hypovolemia and/or vasospasm and/or left and right heart dysfunction. (10) Causes of hemodynamic disorders can be rapidly and qualitatively evaluated so that the orientation of treatment can be clarified by TEECC. (11) A full range of quantitative indicators for refined hemodynamic management in critically ill patients can be provided by TEECC. (12) TEECC helps to accurately assess volume status and predict fluid responsiveness.(13) TEECC is specially suitable for accurate quantitative assessment of cardiac function.(14) Mini TEE provides long-term continuous hemodynamic monitoring. (15) Standard views are easy to be acquired by TEECC, which is a premise for accurate and repeatable measurements, and a guarantee for assessment of effect and risk of therapy. (16) Compared with invasive hemodynamic monitoring, TEECC is minimally invasive, with low infection risk and high safety.(17) In patients with acute cor pulmonale (ACP) under condition of right ventricular dysfunction and low cardiac output, TEECC is a key tool for assessment. (18) TEECC should be implemented actively when suspicious of left to right shunt in critically ill patients who occurred hypotension that hard to explain the cause. (19) TEECC should be implemented actively when suspicious of right to left shunt in critically ill patients who occurred hypoxemia that hard to explain the cause. (20) TEECC is preferred in hemodynamics monitoring under prone position of ventilated patients.(21) TEECC is an imperative means to achieve over-all management of extracorporeal membrane oxygenation (ECMO) therapy, especially for all-round hemodynamic monitoring. (22) Three basic views is recommended to be used to simplify TEE assessment during cardiac arrest so that reversible causes could be identified, and resuscitation could be guided. (23) The flow related echodynamic evaluation (TEECC-FREE) workflow is preferred in refined hemodynamics monitoring and therapy. (24) Simple workflow of TEECC could be implemented in special critical clinical scenarios. (25) Application of TEECC is highly secure; however, impairments of procedure should also be alert by operators. (26) Pitfalls in application of TEE should be paid attention to by the critical care physician. (27) Timely and rationally application of TEECC is in favor of diagnosis and treatment of critically ill patients and may improve the prognosis.

Abstract
Objective: To evaluate the role of multidisciplinary team (MDT) clinic in the diagnosis of pancreatic diseases and patient compliance with MDT advice in the current medical system. Methods: The study included 512 patients that had visited the pancreas-oriented MDT clinic of Zhongshan Hospital between May 2015 and May 2019.The clinical and pathological data were collected and analyzed retrospectively. Diseases were classified in accordance with 2010 WHO classification of tumors of the digestive system and usual clinical practices. Compliance was determined according to whether a patient received corresponding therapies or undergoing further checks or follow-ups. Results: Among the 512 patients that had visited the MDT clinic, 121 patients were referred due to undetermined diagnosis. Classified according to the final diagnosis, the rate of undetermined diagnosis in different disease categories from high to low in order was inflammatory diseases of the pancreas (75.0%, 24/32), other lesions of the pancreas (56.1%,23/41), pancreatic cystic lesions (19.1%,17/89), pancreatic carcinomas (18.3%,48/262) and pancreatic neuroendocrine neoplasms (pNEN)(10.2%,9/88). The MDT clinic made diagnosis to 68 patients directly with an accuracy of 89.7%. The rate of compliance in the entire cohort was 63.4%. The rate of compliance of patients from June 2017 to May 2019 (68.4%) was higher than that of patients from May 2015 to May 2017(59.6%). The compliance rate of patients in different disease categories from high to low in order was inflammatory diseases of the pancreas(84.4%, 27/32), pancreatic carcinomas (67.9%, 178/262), pNEN(60.2%,53/88), other lesions of the pancreas (56.1%,23/41), and pancreatic cystic lesions(49.4%, 44/89). The compliance rate of patients with different MDT advice from high to low in order was best supportive care(78.6%,22/28), antitumor approaches beyond surgery(71.6%,159/222), further tests(62.6%, 77/123), surgery(53.7%, 65/121) and follow-up(49.2%, 31/63). In patients suggested for surgery, the compliance rate of patients with carcinomas(67.4%, 33/49) was higher than patients with other kinds of neoplasms. Conclusions: MDT clinic could facilitate the diagnosis of pancreatic diseases conveniently and inexpensively. The overall compliance rate of MDT clinic patients is rather low, and patients with carcinomas have a relative high rate of compliance with the suggestion of surgery.

Abstract
Glycogen synthase kinase beta (GSK3β) is considered as a promising target for lung cancer treatment and its inhibitor lithium chloride (LiCl) is widely regarded as having potent anti-proliferative and apoptosis-modulating activities. Proliferating cell nuclear antigen (PCNA), as an auxiliary protein for DNA polymerase delta, which regulates DNA replication and repair, has been reported to play an important role in regulating apoptosis. Here, we showed that GSK3β interacted with PCNA in H1299 lung adenocarcinoma cells using GST pull-down and co-immunoprecipitation experiments. We discovered that their interaction can be enhanced within the first 3 h after UVC irradiation and decreased gradually with time. Overexpression of PCNA protein decreased GSK3β Ser9 phosphorylation, whereas knockdown of PCNA using small interfering RNA (siRNA) increased Ser9 phosphorylated GSK3β, which was attenuated by phosphatidylinositol 3-kinase (PI3K) inhibitor LY294002 after UVC irradiation, indicating the involvement of the PI3K-AKT pathway. Functional analyses suggested that downregulation of PCNA sensitized H1299 cells to LiCl-induced apoptosis. Thus, our results unraveled a novel regulatory of GSK3β by PCNA and provided a promising direction for treatment of lung cancer.

Abstract
Objective: To study the application value of augmented-reality (AR) surgical navigation technology combined with indocyanine green (ICG) molecular fluorescence imaging in three-dimensional (3D) laparoscopic hepatectomy. Methods: The clinical data of forty-eight patients who had undergone 3D laparoscopic hepatectomy for hepatocellular carcinoma at First Department of Hepatobiliary Surgery, Zhujiang Hospital, Southern Medical University from January 2018 to April 2019 were retrospectively analyzed.The patients were divided into two groups: the group of 3D laparoscopic hepatectomy navigated by augment reality technology combined with ICG molecular fluorescence imaging (Group A) , and group of conventional 3D laparoscopic hepatectomy (Group B) . Patients in Group A (n=23) underwent 3D laparoscopic hepatectomy using augmented-reality technology combined with ICG molecular fluorescence imaging. In this group, the self-developed three-dimensional laparoscopic augmented-reality surgical navigation system (No. 2018SR840555) was operated to project the preoperative three-dimensional model to the surgical field, and the use of this system in combination with ICG molecular fluorescence imaging navigated laparoscopic hepatectomy. No surgical navigation technology was applied in Group B (n=25) . All patients signed the informed consent, which were in accordance with the requirements of medical ethics (Ethics No.: 2018-GDYK-003) . The preoperative data, surgical indicators and postoperative complications between the two groups were compared and analyzed. Results: The median amount of intraoperative blood loss of Group A was 250 (200) ml (M (Q(R)) ) , which was significantly lower than that of Group B (300 (150) ml) (Z=-2.307, P=0.021) .The transfusion rate of Group A was 13.0% (3/23) , which was significantly lower than that of Group B (40.0%, 10/25) (χ(2)=4.408, P=0.036) .The median postoperative hospitalization time of Group A was 8 (2) d, which was significantly shorter than that of Group B (11 (6.5) d) (Z=-2.694, P=0.007) . There were no serious complications and perioperative death in both groups.The incidence of postoperative complications in Group A was 17.4% (4/23) , which was not significantly different from that in group B (28%, 7/25) (χ(2)=0.763, P=0.382) . Conclusion: Augmented-reality surgical navigation technology combined with ICG molecular fluorescence imaging has better effect in 3D laparoscopic hepatectomy.

Abstract
This study aims to investigate advantages of robot-assisted minimally invasive esophagectomy (RAMIE) over video-assisted minimally invasive esophagectomy (VAMIE) in treating esophageal squamous cell carcinoma by applying propensity score-matched analysis. From April 2016 to January 2018, consecutive patients undergoing a McKeown RAMIE or VAMIE for esophageal squamous cell carcinoma were prospectively included for analysis. Baseline data, pathological findings, and short-term outcomes of the two groups (RAMIE group and VAMIE group) were collected and compared. Propensity score-matched analysis was applied to generate matched pairs for further comparison. Finally, we included a total of 151 patients (RAMIE group: 79 patients, VAMIE group: 72 patients) for analysis. In the analysis of unmatched cohort, RAMIE yielded a significantly larger number of total dissected lymph nodes (mean: 20.6 ± 8.8 vs. 17.9 ± 7.7; P = 0.048) and abdominal lymph nodes (mean: 9.5 ± 6.8 vs. 7.4 ± 5.1; P = 0.039) than VAMIE. However, there was no significantly different risk of major complications between the two groups. In the analysis of matched cohort, RAMIE still yielded a significantly larger number of total dissected lymph nodes (P = 0.006) and abdominal lymph nodes (P = 0.042) than VAMIE. There was still no increased risk of postoperative major complications in the RAMIE group compared to the VAMIE group. Moreover, RAMIE was found to yield significantly more left recurrent laryngeal nerve lymph nodes (mean: 1.0 ± 1.8 vs. 0.4 ± 0.8; P = 0.033) than VAMIE without increasing the risk of recurrent laryngeal nerve paralysis. Therefore, RAMIE may have the advantage of lymphadenectomy over VAMIE without increasing any risk of postoperative major complications. Further well-conducted studies, however, are needed to confirm our conclusions.

Abstract
Essentials Perioperative blood loss and inflammatory response can significantly affect recovery after surgery. We studied the effects of multiple-dose oral tranexamic acid on blood loss and inflammatory response. A postoperative four-dose regimen brought about maximum reduction in postoperative blood loss. A postoperative four-dose regimen reduced inflammatory response and promoted early rehabilitation. SUMMARY: Background Tranexamic acid (TXA) can reduce blood loss and the inflammatory response at multiple doses in total knee arthroplasty patients. However, the optimal regimen has not been determined. Objectives To identify the most effective regimen for achieving maximum reductions in blood loss and the inflammatory response. Patients/Methods Two hundred and seventy-five patients were randomized to receive a placebo (group A), a single 2-g oral dose of TXA 2 h preoperatively followed by 1 g of oral TXA 3 h postoperatively (group B), a single dose followed by 1 g of oral TXA 3 h and 7 h postoperatively (group C), a single dose followed by 1 g of oral TXA 3 h, 7 h and 11 h postoperatively (group D), or a single dose followed by 1 g of oral TXA 3 h, 7 h, 11 h and 15 h postoperatively (group E). The primary outcome was total blood loss on postoperative day (POD) 3. Secondary outcomes included a decrease in the hemoglobin level, coagulation parameters, inflammatory marker levels, and thromboembolic complications. Results Groups D and E had significantly lower blood loss and smaller decreases in hemoglobin level than groups A, B, and C, with no significant difference on POD 3 between groups D and E. Significantly enhanced coagulation was identified for the four multiple-dose regimens; however, all thromboelastographic parameters remained within normal ranges. Group E had the lowest inflammatory marker levels and pain, and the greatest range of motion. No thromboembolic complications were identified. Conclusion The four-dose regimen yielded the maximum reductions in blood loss and inflammatory response, improved analgesia, and promoted early rehabilitation. Further studies are required to ensure that these findings are reproducible.

Abstract
Objective: To study the epidemiological characteristics and related factors of dyslipidemia among adult residents in Xinjiang Uygur Autonomous Region (Xinjiang) in 2013-2014. Methods: A total of 4 120 adult residents consisting of Han and Uygur group aged over 18 years old were selected by using a stratified cluster random sampling method in 8 counties of Xinjiang from 2013 to 2014. The related factors of dyslipidemia were collected by questionnaire and physical measurement. The total cholesterol, triglyceride, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol were detected by enzyme method. Factors associated with dyslipidemia were analyzed by chi-squared test and a multivariate unconditioned logistic regression model adjusted for gender, urban or rural area, age-group, body mass index (BMI), central obesity, smoking, drinking, education attainment, diabetes mellitus and hypertension. Results: The prevalence of dyslipidemia was 45.00% (1 854 cases). The prevalence of dyslipidemia was higher in Uygur group (47.80% (977/2 044)) than that in Han group (42.24% (877/2 076)) (χ(2)=12.84, P<0.001). The analysis showed that dyslipidemia was related with gender (OR=0.41, 95%CI: 0.33-0.51), urban area (OR=0.54, 95%CI: 0.39-0.76), BMI (overweight group (OR=1.52, 95%CI: 1.18-1.96); obesity group (OR=2.20, 95%CI: 1.64-2.96)), central obesity (OR=1.66, 95%CI: 1.29-2.14) and diabetes mellitus (OR=1.49, 95%CI: 1.06-2.11) in Uygur group. The analysis also showed that dyslipidemia was related with BMI (overweight group (OR=1.72, 95%CI: 1.32-2.25), obesity group (OR=2.60, 95%CI: 1.85-3.64)), central obesity (OR=1.45, 95%CI: 1.13-1.87), smoking (OR=1.46, 95%CI: 1.09-1.95), diabetes mellitus (OR=1.77, 95%CI: 1.38-2.25) and hypertension (OR=1.62, 95%CI: 1.31-2.00) in Han group. Conclusions: The prevalence of dyslipidemia in Xinjiang was higher than the national average prevalence. The prevalence of dyslipidemia in Uygur group was significantly higher than that in Han group. The gender, living area, BMI, central obesity and diabetes mellitus were risk factors of dyslipidemia in Uygur group, and BMI, central obesity, smoking, diabetes mellitus and hypertension were risk factors of dyslipidemia in Han group in Xinjiang.

Abstract
Whether the robot-assisted minimally invasive esophagectomy (RAMIE) has any advantages over the video-assisted minimally invasive esophagectomy (VAMIE) remains controversial. In this study, we tried to compare the short-term outcomes of RAMIE with that of VAMIE in treating middle thoracic esophageal cancer from a single medical center. Consecutive patients undergoing RAMIE or VAMIE for middle thoracic esophageal cancer from April 2016 to April 2017 were prospectively included for analysis. Baseline data and pathological findings as well as short-term outcomes of these two group (RAMIE group and VAMIE group) patients were collected and compared. A total of 84 patients (RAMIE group: 42 patients; VAMIE group: 42 patients) were included for analysis. The baseline characteristics between the two groups were comparable. RAMIE yielded significantly larger numbers of total dissected lymph nodes (21.9 and 17.8, respectively; P = 0.042) and the right recurrent laryngeal nerve (RLN) lymph nodes (2.1 and 1.2, respectively; P = 0.033) as well as abdominal lymph nodes (10.8 and 7.7, respectively; P = 0.041) than VAMIE. Even though RAMIE may consume more overall operation time, it could significantly decrease total blood loss compared to VAMIE (97 and 161 mL, respectively; P = 0.015). Postoperatively, no difference of the risk of major complications or hospital stay was observed between the two groups. In conclusion, RAMIE had significant advantage of lymphadenectomy especially for dissecting RLN lymph nodes over VAMIE with a comparable rate of postoperative complications. Further randomized controlled trials are badly needed to confirm and update our conclusions.

Abstract
Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound, the examiner and interpreter of the image are critical care medicine physicians. The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes. With the idea of critical care medicine as the soul, it can integrate the above information and clinical information, bedside real-time diagnosis and titration treatment, and evaluate the therapeutic effect so as to improve the outcome. CUS is a traditional technique which is applied as a new application method. The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept, implementation and application of CUS. It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure. At the same time, the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications, and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS. Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group, based on the rich experience of clinical practice in critical care and research, combined with the essence of CUS, to learn the traditional ultrasonic essence, established the clinical application technical specifications of CUS, including in five parts: basic view and relevant indicators to obtain in CUS; basic norms for viscera organ assessment and special assessment; standardized processes and systematic inspection programs; examples of CUS applications; CUS training and the application of qualification certification. The establishment of applied technology standard is helpful for standardized training and clinical correct implementation. It is helpful for clinical evaluation and correct guidance treatment, and is also helpful for quality control and continuous improvement of CUS application.

Abstract
Background The aim of this study was to evaluate the association between hematinic deficiencies and recurrent aphthous stomatitis (RAS). Material and Methods 517 RAS patients and 187 healthy controls were enrolled in the present study. Hematinic deficiencies, including serum ferritin, folic acid, and vitamin B12 deficiencies were assessed for each participant. Gender and age were taken into account and the collected data were statistically analysed. Results Compared with the healthy controls, a significantly higher overall frequency of hematinic deficiencies was found in RAS patients (p<0.001). When gender and age were taken into account, significant differences in hematinic deficiencies were observed among RAS patients. Serum ferritin deficiency was much more common in young and middle-aged female RAS patients (age<60). Serum folate deficiency and serum vitamin B12 deficiency were both much more common in the young adult group of male RAS patients (21–40 years of age). Logistic regression analysis revealed that both gender and age have significant correlation with the presence of hematinic deficiencies in the RAS patients. Conclusions Significant variations in hematinic deficiencies were demonstrated in RAS patients across different genders and age groups. We suggest that further studies on the hematinic deficiencies of RAS patients should take into account the gender and age of participants. Key words:Recurrent aphthous stomatitis, hematinic deficiencies, gender, age.

Abstract
To establish the experts consensus on the right heart function management in critically ill patients. The panel of consensus was composed of 30 experts in critical care medicine who are all members of Critical Hemodynamic Therapy Collaboration Group (CHTC Group). Each statement was assessed based on the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) principle. Then the Delphi method was adopted by 52 experts to reassess all the statements. (1) Right heart function is prone to be affected in critically illness, which will result in a auto-exaggerated vicious cycle. (2) Right heart function management is a key step of the hemodynamic therapy in critically ill patients. (3) Fluid resuscitation means the process of fluid therapy through rapid adjustment of intravascular volume aiming to improve tissue perfusion. Reversed fluid resuscitation means reducing volume. (4) The right ventricle afterload should be taken into consideration when using stroke volume variation (SVV) or pulse pressure variation (PPV) to assess fluid responsiveness.(5)Volume overload alone could lead to septal displacement and damage the diastolic function of the left ventricle. (6) The Starling curve of the right ventricle is not the same as the one applied to the left ventricle,the judgement of the different states for the right ventricle is the key of volume management. (7) The alteration of right heart function has its own characteristics, volume assessment and adjustment is an important part of the treatment of right ventricular dysfunction (8) Right ventricular enlargement is the prerequisite for increased cardiac output during reversed fluid resuscitation; Nonetheless, right heart enlargement does not mandate reversed fluid resuscitation.(9)Increased pulmonary vascular resistance induced by a variety of factors could affect right heart function by obstructing the blood flow. (10) When pulmonary hypertension was detected in clinical scenario, the differentiation of critical care-related pulmonary hypertension should be a priority. (11) Attention should be paid to the change of right heart function before and after implementation of mechanical ventilation and adjustment of ventilator parameter. (12) The pulmonary arterial pressure should be monitored timingly when dealing with critical care-related pulmonary hypertension accompanied with circulatory failure.(13) The elevation of pulmonary aterial pressure should be taken into account in critical patients with acute right heart dysfunction. (14) Prone position ventilation is an important measure to reduce pulmonary vascular resistance when treating acute respiratory distress syndrome patients accompanied with acute cor pulmonale. (15) Attention should be paid to right ventricle-pulmonary artery coupling during the management of right heart function. (16) Right ventricular diastolic function is more prone to be affected in critically ill patients, the application of critical ultrasound is more conducive to quantitative assessment of right ventricular diastolic function. (17) As one of the parameters to assess the filling pressure of right heart, central venous pressure can be used to assess right heart diastolic function. (18). The early and prominent manifestation of non-focal cardiac tamponade is right ventricular diastolic involvement, the elevated right atrial pressure should be noticed. (19) The effect of increased intrathoracic pressure on right heart diastolic function should be valued. (20) Ttricuspid annular plane systolic excursion (TAPSE) is an important parameter that reflects right ventricular systolic function, and it is recommended as a general indicator of critically ill patient. (21) Circulation management with right heart protection as the core strategy is the key point of the treatment of acute respiratory distress syndrome. (22) Right heart function involvement after cardiac surgery is very common and should be highly valued. (23) Right ventricular dysfunction should not be considered as a routine excuse for maintaining higher central venous pressure. (24) When left ventricular dilation, attention should be paid to the effect of left ventricle on right ventricular diastolic function. (25) The impact of left ventricular function should be excluded when the contractility of the right ventricle is decreased. (26) When the right heart load increases acutely, the shunt between the left and right heart should be monitored. (27) Attention should be paid to the increase of central venous pressure caused by right ventricular dysfunction and its influence on microcirculation blood flow. (28) When the vasoactive drugs was used to reduce the pressure of pulmonary circulation, different effects on pulmonary and systemic circulation should be evaluated. (29) Right atrial pressure is an important factor affecting venous return. Attention should be paid to the influence of the pressure composition of the right atrium on the venous return. (30) Attention should be paid to the role of the right ventricle in the acute pulmonary edema. (31) Monitoring the difference between the mean systemic filling pressure and the right atrial pressure is helpful to determine whether the infusion increases the venous return. (32) Venous return resistance is often considered to be a insignificant factor that affects venous return, but attention should be paid to the effect of the specific pathophysiological status, such as intrathoracic hypertension, intra-abdominal hypertension and so on. Consensus can promote right heart function management in critically ill patients, optimize hemodynamic therapy, and even affect prognosis.

Abstract
The technique of thoracoscopic lung surgery has gradually matured. Nowadays, thoracoscope is recommended as the most preferred approach for surgical treatment of early stage non-small cell lung cancer in different guidelines. However, there are still some cases of accidential major bleeding due to vascular injury during thoracoscopic lung surgery. The wall of the hilum vessels is relatively thin. These vessels often involve a great portion of the cardiac output blood flow. Once the injury happened, the emergent condition may be life-threatening due to massive blood loss. Therefore, this became an important factor which hindered the development of thoracoscopic lung surgery. In this review, details of the vascular injury in thoracoscopic lung surgery were summarized, including the incidence of vascular injury, commonly injured sites and reasons of the injuries. Among all the cases of thoracoscopic major pulmonary resection, 2.9% to 9.2% may suffer from vascular injury during the operation. The most commonly injuried sites are pulmonary artery and the branches, and this is also the most critical situation during thoracoscopic lung surgery. Hilum adhesion is the most important risk factor for vascular injury. On the one hand, the suction-compressing angiorrhaphy technique was developed for bleeding control and angioplasty. On the other hand, the strategies like pre-control of the pulmonary, cut the bronchus in advance, and fire the bronchus and pulmonary artery together may decrease the incidence of vascular injury in patients with risk factors.

Abstract
Objective: To evaluate the excursion of the diaphragm and analyze the value in predicting weaning from mechanical ventilation in intensive care unit patients. Methods: The patients with mechanical ventilation (>48 hours) in ICU at Hebei Forth Medical University Hospital from June 2014 to December were classified into a success group or a failure group according to the weaning outcome. T-piece spontaneous breathing (SBT), airway occlusion pressure at 0.1 sec (P(0.1)) and maximal inspiratory pressure (MIP), rapid shallow breathing index (RSBI) and P(0.1)/MIP were measured or calculated. During the period of the 1st hour SBT, the excursion of diaphragm was measured with ultrasonography. The predictive value of each parameter to weaning was evaluated with ROC curve. Results: A total of 98 patients were enrolled in this study, including 74 successfully weaning and 24 failed. There were significant differences between two groups(success group and failure group) in P(0.1)[(2.00±2.00)cmH(2)O (1 cmH(2)O=0.098 kPa) vs (3.00±2.75)cmH(2)O, P<0.05], RSBI (39.14±16.81 vs 52.00±19.18, P<0.05), left diaphragmatic excursion [(1.12±0.97)cm vs (0.69±1.00)cm, P<0.001], right diaphragmatic excursion(1.87±0.75)cm vs (1.17±0.76)cm, P<0.001] and mean value of left and right diaphragmatic excursion [(1.57±0.52)cm vs (0.83±0.53)cm, and P<0.001]. The ventilation time [2.00(2.00-4.00)d vs 4.00(2.00-5.00)d], ICU hospital lengths of stay [4.50(3.00-7.25)d vs 8.50(6.25-15.25)d] and total hospital lengths of stay[20.00(15.00-25.25)d vs 25.00(20.25-37.25)d] were also statistically significant in success group and failure group respectively (all P<0.05). The cutoff value of diaphragmatic excursion for predicting successful extubation was determined to be 1.14 cm by ROC curve analysis. The sensitivity of diaphragmatic excursion to predict successful weaning was 89.2% and the specificity was 75.0%, the AUC(ROC) was 0.849. Conclusion: As an early predictor of diaphragmatic dysfunction, diaphragmatic excursion is probably superior to the traditional parameters in predicting weaning from ventilator in ICU patients.

Abstract
Objective: To observe and explore the effects of different tidal volume (VT) ventilation on right ventricular (RV) function in patients with critical respiratory failure. Methods: Consecutive respiratory failure patients who were treated with invasive ventilator over 24 h in the Department of Critical Care Medicine at the Fourth Hospital of Hebei Medical University from June to December in 2015 were enrolled in this study.Clinical data including patients' vital signs, ventilator parameters and RV echocardiography were collected within 6 h (D0), day1(D1), day2 (D2) and day3 (D3) after ventilation started.According to the VT, patients with acute respiratory distress syndrome (ARDS) were assigned to low VT group [S6, ≤6 ml/kg predicted body weight (PBW)] and high VT group (L6, >6 ml/kg PBW), while non-ARDS patients were also assigned to low VT group (S8, ≤8 ml/kg PBW) and high VT group (L8, >8 ml/kg PBW). Results: A total of 84 patients were enrolled in this study.44.2% ARDS patients and 58.5% non-ARDS patients were in low VT groups.After ventilation, tricuspid annulus plane systolic excursion(TAPSE)decreased progressively in S6 [from 18.30(16.70, 20.70) mm to 17.55(15.70, 19.50) mm, P=0.001], L6 [from 19.50(17.00, 21.00) mm to 16.30(15.00, 18.00) mm P=0.001], S8[from 18.00(16.00, 21.00) mm to 16.50(15.50, 18.00) mm, P=0.001] and L8 [from 19.00(17.50, 21.50) mm to 16.35(15.15, 17.00) mm, P=0.001] groups.However, TAPSE decreased less in small VT groups (S6 and S8) than those of in large VT groups (S8 and L8) without significant differences.There were not statistical differences between different VT groups in terms of ventilation days, including right ventricle area/left ventricle area (RV(area)/LV(area)), TAPSE, peak mitral flow velocity of the early rapid filling wave (E), peak mitral flow velocity of the late rapid filling wave (A), early diastolic velocity of the tricuspid annulus (e'), pulmonary artery systolic pressure, inferior vena cava diameter (all P>0.05). Compared to L6 group, low VT (S6 group) resulted in decreased mortality at 28 days [1/19 vs 37.5%(9/24), P=0.014]. There were not statistical differences between different VT groups in terms of ventilation days, length of intensive care unit stay, length of hospital stay (all P>0.05). Logistic regression analysis showed that VT could be the independent factor of TAPSE (OR=1.104, 95%CI 0.100-1.003, P=0.049). Conclusions: Positive pressure mechanical ventilation resulted in RV systolic dysfunction .Lower VT may have the protective effect on RV function.

Abstract
Diabetes mellitus has the probability to impair the anastomotic healing and cause postesophagectomy anastomotic leakages but previous studies showed controversial results. This review aims to summary the impact of diabetes mellitus on the risk of anastomotic leakage after esophagectomy. We searched the PubMed and EMBASE databases to recognize English articles that met our eligibility criteria. Odds ratio with 95% confidence interval serves as the appropriate summarized statistic. Sensitivity analysis, meta-regression analysis, and publication bias tests were also performed to perceive potential bias risks. Finally, 16 observational studies with 12359 surgical patients were included. An overall analysis identified that diabetes mellitus was significantly associated with the risk of anastomotic leakage after esophagectomy (odds ratio = 1.63; 95% confidence interval = 1.25-2.12; P < 0.001). Further subgroup analysis showed a significant impact of diabetes mellitus in surgical populations from the Europe and America (odds ratio = 1.42; 95% confidence interval = 1.22-1.65; P < 0.001) but not in the Asian populations (odds ratio = 2.27; 95% confidence interval = 0.86-6.05; P = 0.1). The robustness of these estimates was confirmed by meta-regression analysis and sensitivity analysis. No significant publication bias exists between studies. In conclusion, this systematic review demonstrates that diabetes mellitus can be a significant risk factor of anastomotic leakage for patients undergoing esophagectomy. Our findings need to be further confirmed and modified by more well-designed worldwide multivariable analyses in the future.

Abstract
Objective: To understand tobacco use rate and explore the factors associated with tobacco use in middle school students in China. Methods: A self-administered questionnaire survey was conducted among 155 117 eligible middle students selected through multi-stage stratified cluster sampling from 31 provinces of China. The questionnaire consists of the following topics: tobacco use and cessation, passive smoking, access to tobacco products, tobacco control and tobacco advertisement, and knowledge about and attitudes to tobacco. Software SAS 9.3 was used for sample weighting and data analysis. Results: Current tobacco use rate was 6.9% in middle school students in China. The rate was higher in boys (11.2%) than in girls (2.2%), and in rural area (7.8%) than in urban area (4.8%). Students in western area had the highest tobacco use rate (10.3%), followed by the students in middle area (6.4%), and the rate in students in eastern area was lowest (4.5%). Parent smoking (especially mother smoking), friend smoking, teacher smoking, pocket money for a week>20 yuan, tobacco advertisement or promotion, passive smoking, misconception of tobacco addiction, active attitude to smoking behavior were the risk factors for tobacco use. Conclusions: Smoking rate in boys in China was higher than the average global level. A comprehensive intervention strategy by Framework Convention on Tobacco Control should be used to reduce tobacco use in adolescents, including health education, increasing cigarette price, banning tobacco advertisement and promotion, and smoke-free legislation.

Abstract
OBJECTIVE Compare the results of molecular diffusion and mass flow in the interstitial space(ISS) displayed by using optical and magnetic probes and study partitioned drainage of the brain interstitial fluid (ISF). METHODS In the study, 36 male SD rats were randomly divided into fluorescent inspection group (18), magnetic tracer group (18). Then they were divided equally into caudate nucleus (Cn), thalamus (T) and substantia nigra (Sn) subgroup, 6 rats in each subgroup. Referencing the brain stereotaxic atlas, the coronal globus pallidus as center level, Cn, T or Sn were acted as puncture positioning target. A 10 μL microsyringe was stereotaxically positioned and the lucifer yellow (LY) solution of 2 μL 10 mmol/L was infused into centric position. The coronary slices undergo cardiac perfusion and fix respectively in time point Cn 3 h, T 2 h and Sn 1 h. The rat brain was placed in rat stainless steel brain matrices and cut backward along visual intersection. The injection point of coronal slice as the center level, take 3 slices in front of the center level and 2 slices behind of it. 1 mm for each slice and 6 slices in total. Then slices were detected by laser scanning confocal microscope (LSCM). Simultaneous, in the same coordinate brain regions of another three groups, a gadolinium-diethylene triamine pentaacetic acidm (Gd-DTPA) solution of 2 μL 10 mmol/L was infused into different injection and detected by MRI tracer-based method. Then the Radiant can be used to measure distribution area of Gd-DTPA. RESULTS LY and Gd-DTPA have different distribution regions in Cn, T and Sn. After LY and Gd-DTPA were introduced into the Cn subgroup 3 h, compare the 1 to 6 levels distribution area of LY and Gd-DTPA as follows: (10.95±4.27) mm2 vs. (8.33±2.25) mm2, (18.16±4.74) mm2 vs. (16.42±2.88) mm2, (24.57±3.65) mm2 vs. (20.75±2.29) mm2, (34.81±3.32) mm2 vs. (28.88±1.51) mm2, (30.53±3.12) mm2 vs. (20.92±2.75) mm2, (12.15±4.92) mm2 vs. (10.00±1.89) mm2. The statistical analysis of every level was made by T test, and the difference of the distribution area between the two tracers were not statistically significant (t=0.940, P=0.400; t=0.546, P=0.614; t=1.534, P=0.200; t=2.809, P=0.480; t=2.693, P=0.055; t=0.707, P=0.518); After LY and Gd-DTPA were introduced into the T subgroup 2 h, compare the 1-6 levels distribution area of LY and Gd-DTPA as follows: (5.56±4.61) mm2 vs. (3.33±2.25) mm2, (16.21±3.36) mm2 vs. (11.42±2.88) mm2, (19.00±5.21) mm2 vs. (15.75±2.29) mm2, (25.32±5.49) mm2 vs. (22.33±3.25) mm2, (17.34±5.31) mm2 vs. (15.92±2.75) mm2, (7.67±6.19) mm2 vs. (5.00±1.89) mm2. The statistical analysis of every level was made by T test, and the difference of the distribution area between the two tracers were not statistically significant (t=0.753, P=0.493; t=1.875, P=0.134; t=0.990, P=0.378; t=0.810, P=0.464; t=0.413, P=0.701; t=0.716, P=0.514); After LY and Gd-DTPA were introduced into the Sn subgroup 1 h, compare the 1-6 levels distribution area of LY and Gd-DTPA as follows: (6.78±4.56) mm2 vs. (4.75±2.00) mm2, (12.65±5.04) mm2 vs. (10.44±1.13) mm2, (19.51±6.54) mm2 vs. (17.55±0.30) mm2, (28.72±5.45) mm2 vs. (24.48±1.32) mm2, (21.34±4.42) mm2 vs. (17.72±0.25) mm2, (13.00±5.46) mm2 vs. (12.00±2.88) mm2. The statistical analysis of every level was made by T test and the difference of the distribution area between the two tracers were not statistically significant (t=0.705, P=0.519; t=0.743, P=0.499; t=0.517, P=0.656; t=1.310, P=0.260; t=1.416, P=0.292; t=0.281, P=0.793), but the distribution area of LY is slightly more than Gd-DTPA. CONCLUSION LSCM imaging technology confirmed partitioned drainage of the brain ISF found by MRI tracer-based method and provided technology and method validation for MRI tracer-based method. LSCM imaging technology with higher contrast and resolution, therefore more sophisticated partitioned drainage of the brain interstitial fluid were got.

Abstract
OBJECTIVE Inflammation as a significant influence factor plays an important role in the formation and rupture of intracranial aneurysms. However, based on plenty of related studies, it is believed that the hepatocyte growth factor (HGF) is able to prevent vascular inflammation. This paper, therefore, explored the role and mechanism of endogenous HGF in the pathogenesis of intracranial aneurysms. MATERIALS AND METHODS 16 blood samples were collected from the intracranial aneurysms and the lumens of the femoral artery of 16 patients. Comparison and quantitative detection of HGF serum concentrations in an aneurysm and femoral artery samples according to the immune assay based on Luminex were followed. The tissue of superficial temporal artery (STA) and ruptured or unruptured intracranial aneurysm from the patients (n=10) who were performed surgical clipping of craniotomy was then collected. The intracranial aneurysm model was induced by surgery on adult c57/B16 mouse and grouping administration of c-Met antagonist PF-04217903 or its solvent DMSO for 3 weeks. Then, the brains of the experimental mouse were dissected and examined whether there were intracranial aneurysms and/or subarachnoid hemorrhage (SAH). The procedures followed by treatment of human endothelial cells cultured in vitro, smooth muscle cells and monocytes with HGF and PF-04217903 lipopolysaccharide (LPS). Through Real-time fluorescence quantitative PCR, with ΔΔCt methods, we used the expressions of β-actin normalized inflammatory factor [intercellular adhesion molecule-1 (ICAM-1)], vascular cell adhesion molecule-1 (VCAM-1), E-selectin, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), monocyte chemoattractant protein-1 (MCP-1), cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2) and transforming growth factor-β (TGF-β). RESULTS It was found that the concentration of HGF (1076±656) pg/ml from the blood collected from human intracranial aneurysms was significantly higher than that from the femoral artery (196±436) pg/ml (p<0.01). Experimental mouse treated with PF-04217903 (c-Met antagonist) and in control group were induced to form intracranial aneurysms. C-Met antagonists did not alter the formation of intracranial aneurysms (p>0.05), but significantly increased the occurrence of subarachnoid hemorrhage and reduced the survival rate of mice (p<0.05). HGF attenuated the expression of VCAM-1 (p<0.05) and E-selectin (p<0.05) in human aortic endothelial cells CONCLUSIONS: The plasma HGF levels were elevated in intracranial aneurysms, and the HGF and c-Met were expressed in STA and intracranial aneurysms. In the treatment of intracranial aneurysms, HGF signaling pathway reduced inflammation in endothelial cells and prevented the rupture of intracranial aneurysm through c-Met.

Abstract
Chicken skeletal muscle satellite cells are located between the basement membrane and the sarcolemma of mature muscle fibers. Avian broilers have been genetically selected based on their high growth velocity and large muscle mass. The Wuding chicken is a famous local chicken in Yunnan Province that undergoes non-selection breeding and is slow growing. In this study, we aimed to explore differences in the proliferation and differentiation properties of satellite cells isolated from the two chicken breeds. Using immunofluorescence, hematoxylin-eosin staining and real-time polymerase chain reaction analysis, we analyzed the in vitro characteristics of proliferating and differentiating satellite cells isolated from the two chicken breeds. The growth curve of satellite cells was S-shaped, and cells from Wuding chickens entered the logarithmic phase and plateau phase 1 day later than those from Avian chicken. The results also showed that the two skeletal muscle satellite cell lines were positive for Pax7, MyoD and IGF-1. The expression of Pax7 followed a downward trend, whereas that of MyoD and IGF-1 first increased and subsequently decreased in cells isolated from the two chickens. These data indicated that the skeletal muscle satellite cells of Avian chicken grow and differentiate faster than did those of Wuding chickens. We suggest that the methods of breeding selection applied to these breeds regulate the characteristics of skeletal muscle satellite cells to influence muscle growth.

Abstract
Piglet diarrhea is one of the most common factors that affects the benefits of the swine industry. Although recent studies have shown that exon 2 of SLA-DQA is associated with piglet resistance to diarrhea, contributions of genetic variation in the additional exon coding regions of this gene remain unclear. Here, we investigated variation in exons 1, 3 and 4 of the SLA-DQA gene and evaluated their effects on diarrheal infection in 425 suckling piglets. No variation was identified in exon 1. In exon 3, there were eight alleles detected, generated by 14 single nucleotide polymorphisms (SNPs) and three nucleotide deletions, eight SNPs being newly identified. Four allele sequences and three SNPs were identified in exon 4, only one SNP being newly identified. Statistical analysis showed that the genotypes of exon 3 are significantly associated with piglet diarrhea; indeed, genotypes DQA*wb01/wb02 and wb04/wb05 are clearly associated with resistance to piglet diarrhea, as they have the lowest probabilities of infection (P < 0.05). However, no significant association was found between the genotypes of exon 4 and diarrhea (P > 0.05). These results provide important new information concerning the level of genetic diversity at the SLA-DQA locus and suggest that further genetic association studies of piglet diarrhea resistance should include analyses of both exons 2 and 3 of this locus.

Abstract
Piglet diarrhea is one of the primary factors that affects the benefits of the swine industry. Recent studies have shown that exon 2 of the swine leukocyte antigen-DQA gene is associated with piglet resistance to diarrhea; however, the contributions of additional exon coding regions of this gene remain unclear. Here, we detected and sequenced variants in the exon 3 region and examined their associations with diarrhea infection in 425 suckling piglets using the polymerase chain reaction-single-strand conformational polymorphism and sequencing analysis. The results revealed that exon 3 of the swine leukocyte antigen-DQA gene is highly polymorphic and pivotal to both diarrhea susceptibility and resistance in piglets. We identified 14 genotypes (AA, AB, BB, BC, CC, EE, EF, BE, BF, CF, DD, DH, GG, and GF) and eight alleles (A-H) that were generated by 14 nucleotide variants, eight of which were novel, and three nucleotide deletions. Statistical analyses revealed that the genotypes AB and EF were associated with resistance to diarrheal disease (P < 0.05), and the genotype DD may contribute to diarrhea susceptibility but was unique to Large White pigs (P > 0.05). These results elucidate the genetic and immunological background to piglet diarrhea, and provide useful information for resistance breeding programs.

Abstract
Background The aim of this study was to assess the serum zinc levels in patients with common oral mucosal diseases by comparing these to healthy controls. Material and Methods A total of 368 patients, which consisted of 156 recurrent aphthous stomatitis (RAS) patients, 57 oral lichen planus (OLP) patients, 55 burning mouth syndrome (BMS) patients, 54 atrophic glossitis (AG) patients, 46 xerostomia patients, and 115 sex-and age-matched healthy control subjects were enrolled in this study. Serum zinc levels were measured in all participants. Statistical analysis was performed using a one-way ANOVA, t-test, and Chi-square test. Results The mean serum zinc level in the healthy control group was significantly higher than the levels of all other groups (p < 0.001). No individual in the healthy control group had a serum zinc level less than the minimum normal value. However, up to 24.7% (13/54) of patients with AG presented with zinc deficiency, while 21.2% (33/156) of patients with RAS, 16.4% (9/55) of patients with BMS, 15.2% (7/46) of patients with xerostomia, and 14.0% (8/57) of patients with OLP were zinc deficient. Altogether, the zinc deficiency rate was 19.02% (70/368) in the oral mucosal diseases (OMD) group (all patients with OMD). The difference between the OMD and healthy control group was significant (p <0.001). Gender differences in serum zinc levels were also present, although not statistically significant. Conclusions Zinc deficiency may be involved in the pathogenesis of common oral mucosal diseases. Zinc supplementation may be a useful treatment for oral mucosal diseases, but this requires further investigation; the optimal serum level of zinc, for the prevention and treatment of oral mucosal diseases, remains to be determined. Key words:Oral mucosal diseases, Zinc deficiency, pathogenesis.

Abstract
To develop new ways to breed peanut, we irradiated seeds of the Luhua 11 cultivar with a mixed high-energy particle field at different doses. The embryonic leaflets were extracted as explants and incubated on somatic embryo induction medium and then on somatic embryo germination and regeneration medium. After being grafted, the M1-generation plants were transplanted, and seeds from each M1-generation plant were harvested. In the following year, the M2-generation seeds were planted separately. Some M2-generation plants showed distinct character segregation relative to the mutagenic parent in terms of vigor, fertility, plant height, branch number, and pod size and shape. M2-generation plants that had a high pod weight per plant tended to produce M3-generation offspring that also had a high pod weight per plant, much higher than that of the mutagenic parent, Luhua 11. M4-generation seeds varied greatly in quality, and 35 individuals with an increased fat content (>55%) were obtained. Overall, the results indicate that the combination of mutagenesis via mixed high-energy particle field exposure and tissue culture is promising for peanut breeding.

Abstract
The transcriptomic profiles of human breast cancer cell lines MCF-7 and MDA-MB-435 were investigated using the next-generation RNA sequencing (RNA-Seq). The DESeq package was used to screen the differentially expressed transcripts. A total of 229 genes with a significantly differential expression in MDA-MB-435 cells as compared with MCF-7 cells were obtained. Annotation of the biological functions of these genes through the Database for Annotation, Visualization and Integrated Discovery (DAVID) v6.7 demonstrated that the 229 differentially expressed genes were mainly implicated in the biological functions related to cell adhesion and motion, antigen processing and presentation (via MHC class II), hormone response, extracellular structure organization, tissue remodeling, and cell proliferation regulation. Analysis of the individual genes demonstrated that MDA-MB-435 cells exhibited a higher tendency to metastasis and antigen processing and presentation, and lower ability to hormone response. Twenty most abundant transcripts in MDA-MB-435 cells, such as VIM, TNC, and CD74, represent its high potential for metastasis. Besides the genes previously reported to be involved in tumor metastasis and development, genes newly identified in this study could provide new clues for the diagnosis and prognosis of aggressive breast cancers.

Abstract
Swine leucocyte antigen (SLA) is a highly polymorphic multigene family that plays a crucial role in swine immune response and disease resistance. Here, we identified polymorphisms and gene variations of SLA-DQA exon 2 using polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) and DNA sequencing analysis, and further investigated the correlation between the polymorphisms and piglet diarrhoea in three Chinese native pig breeds (Bamei, Juema and Gansu Black pigs). Consequently, 12 genotypes and 8 alleles including two novel alleles were detected. Nucleotide polymorphism was compared with the actual functional polymorphism in the peptide-binding region (PBR), binding pockets P1, P6 and P9, and the antigen-binding groove, variations in the antigen-binding groove of alleles DQA*01xa01, DQA*01xa03, DQA*01xb01, DQA*We02, DQA*03xb03 and DQA*wy06 were higher than alleles DQA*03xa01 and DQA*03xa03, while amino acid variations in peptide-binding pockets of allele DQA*03xa03 were most abundant among all alleles. The results of association analysis showed the diarrhoea score of Gansu Black pigs (-0.08 ± 0.78) was significantly higher than Bamei and Juema pigs (P < 0.01), and genotype DQA*03xa0103xa01 (0.39 ± 0.54) was significantly higher relative to other genotypes (P < 0.01), while that of genotype DQA*03xa0303xa03 (-1.31 ± 0.88) was markedly lower than scores obtained with genotypes DQA*03xa0103xa01 and DQA*03xa0101xa01 (P < 0.01), as well as DQA*01xa0101xa01 (P < 0.05), indicating that amino acid variations in the peptide-binding pockets play a more important role than the antigen-binding groove in piglet diarrhoea resistance. Further studies on other SLA molecules of native pigs are required to validate the link between this gene complex and diarrhoea.

Abstract
The lymphotoxin beta receptor (LTβR) is a member of the tumor necrosis factor family of receptors (TNFR). It plays a role in regulating lymphoid organogenesis and homeostasis of the immune system. In the present study, the full coding region of a putative LTβR gene of Sus scrofa was amplified by reverse transcription-polymerase chain reaction (RT-PCR) and cloned for the first time (accession Nos. JX457347 and AFU74012). In addition, analysis of the tissue expression profile was carried out via RT-PCR. The full-length coding region of porcine LTβR had 1266 nucleotides (molecular weight, 45.61 kDa; pI, 5.71) and encoded 421 amino acids. Bioinformatic prediction indicates that LTβR belongs to the TNFR superfamily and contains a TNFR domain. The sequence homology analysis revealed that the amino acid sequences of S. scrofa LTβR had 82.9, 82.4, 81.3, 80.5, 78.7, 74.6, and 73.0% identity with those of Equus caballus, Canis lupus, Ailuropoda melanoleuca, Oryctolagus cuniculus, Bos taurus, Mus musculus, and Homo sapiens, respectively. The phylogenetic tree based on the amino acid sequences of LTβR from 8 species revealed that S. scrofa was more closely related to E. caballus, C. lupus, and A. melanoleuca. RT-PCR analysis showed that the porcine LTβR gene was differentially expressed (e.g., high, moderate, low, or nonexistent) in various tissues (e.g., prostate, pituitary, brainstem, and esophagus, respectively). This may be related to differences in the regulation of LTβR in the different tissues.

Abstract
The loss of local chicken breeds as result of replacement with cosmopolitan breeds indicates the need for conservation measures to protect the future of local genetic stocks. The aim of this study is to describe the patterns of polymorphism of the hypervariable control region of mitochondrial DNA (HVR1) in domestic chicken in China's Jiangxi province to investigate genetic diversity, genetic structure and phylo-dynamics. To this end, we sequenced the mtDNA HVR1 in 231 chickens including 22 individuals which belonged to previously published sequences. A neighbor-joining tree revealed that these samples clustered into five lineages (Lineages A, B, C, E and G). The highest haplotype diversity and nucleotide diversity were both found in Anyi tile-liked gray breed. We estimated that the most recent common ancestor of the local chicken existed approximately 16 million years ago. The mismatch distribution analysis showed two major peaks at positions 4 and 9, while the neutrality test (Tajima's D = -2.19, p < 0.05) and Fu's F-statistics (-8.59, p < 0.05) revealed a significant departure from the neutrality assumption. These results support the idea that domestication of chickens facilitated population increases. Results of a global AMOVA indicated that there was no obvious geographic structure among the local chicken breeds analyzed in this study. The data obtained in this study will assist future conservation management of local breeds and also reveals intriguing implications for the history of human population movements and commerce.

Abstract
In China, there are four types of liver abscesses (LAs) that meet the clinical criteria. Pyogenic liver abscesses (PLAs) and amoebic liver abscesses (ALAs) are two of the most common types of abscesses, followed by fungal liver abscesses (FLAs) and hydatid secondary liver abscesses (HsLAs). Diabetes mellitus (DM) is associated with the development of PLAs. However, there is a lack of population-based studies that have evaluated the underlying relationship between LAs (mainly PLAs and FLAs) and DM. We conducted a retrospective study based on a large population to identify the potential differences and factors that affect the mortality of PLA patients in DM and non-DM groups. Our results revealed that the prevalence of DM is 44.3% (158/357) in PLA patients and 35.3% (18/51) in FLA patients. Compared with the non-DM patients, statistically significant differences were found in DM patients according to symptomatology, clinical manifestations, laboratory findings, microbiological characteristics, antimicrobial resistance, clinical treatments and outcomes in relation to mortality. In addition, the status of antibiotic resistance to E. coli and K. pneumoniae, which were isolated from the patient samples, is severe in the area in which the study was conducted. Regarding the treatment of PLAs, our study indicated that broad-spectrum antimicrobial therapy and drug combinations should be recommended and initiated before the pathogens are cultured and identified. In the clinic, therapies that combine percutaneous drainage with antibiotics and surgery with antibiotics are the two most useful strategies for treating an LA. These two combined treatments resulted in satisfactory cure rates. In the DM and non-DM groups, the cure rates for percutaneous drainage with antibiotics were 90.3% and 92.0%, respectively, and the cure rates for surgery with antibiotics were 93.9% and 95.2%, respectively.

Abstract
We present the synthesis and visible-light-induced catalytic activity of one-dimensional (1D) TiO(2)/V(2)O(5) branched heterostructures. The 1D TiO(2)/V(2)O(5) heterostructures were prepared by RF reactive magnetron sputtering of V(2)O(5) onto electrospun TiO(2) nanofibers. Then, the samples were annealed at 300 °C for 2 h in air ambient to form the 1D TiO(2)/V(2)O(5) branched heterostructures. The photodecomposition rate of Rhodamine B (RhB) by the 1D TiO(2)/V(2)O(5) branched heterostructures under visible light was much faster than that of pure TiO(2) nanofibers, revealing that the visible-light-induced catalytic activity of the 1D TiO(2)/V(2)O(5) branched heterostructures was greatly improved. The enhancement of the photocatalytic activity of the 1D TiO(2)/V(2)O(5) branched heterostructures can be ascribed to the coupling with a small bandgap semiconductor material V(2)O(5), where the absorption range is extended, the photogenerated electrons and holes are highly separated and the surface charge carrier transfer rate is promoted.

Abstract
Mass excesses of short-lived A=2Z-1 nuclei (63)Ge, (65)As, (67)Se, and (71)Kr have been directly measured to be -46,921(37), -46,937(85), -46,580(67), and -46,320(141) keV, respectively. The deduced proton separation energy of -90(85) keV for (65)As shows that this nucleus is only slightly proton unbound. X-ray burst model calculations with the new mass excess of (65)As suggest that the majority of the reaction flow passes through (64)Ge via proton capture, indicating that (64)Ge is not a significant rp-process waiting point.

Abstract
Although the crucial role of human papillomaviruses (HPVs), especially HPV-16 in various cancers has been confirmed, the variation of HPV-16 among different cancers have not been investigated in a specific geographic location. In order to elucidate whether similar HPV-16 variants are involved in different kinds of cancers in the same geographic location, the analysis of sequence variants of E6 and E7 oncogenes and L1 gene of HPV-16 in cervical and lung cancers in Sichuan, China, was carried out. Tissue samples from 122 cervical cancers, 104 lung cancers, and 138 controls were subjected to RT-PCR or PCR, sequencing, and sequence analysis. The infection rates of HPV-16 in cervical, lung cancers, and non-malignant controls were 68.9%, 17.3%, and 37.0%, respectively. Asian prototype variants prevailed in cervical and lung cancers, while European prototype variants in non-malignant controls. In comparison to the lung cancer, cervical cancer showed a much higher diversity of HPV-16 oncogenes. These results indicate that in Sichuan, China, Asian prototype variants of HPV-16 are more pathogenic than their European counterparts.

Abstract
Chitosan could form nanoparticles with DNA through electrostatic interaction, and hence protect the DNA from enzymatic degradation. Numerous studies have been working on modifying chitosan aiming at improving its transgenic efficacy. While the modification of chitosan with alkyl group has been shown to significantly improve the cell transfection efficiency, little is known about its impact on its biocompatibility. The current study was performed to investigate the impact of alkylated-chitosan/DNA nanoparticles on the function of the murine macrophage through observing its phagocytic activity and production of pro-inflammatory cytokines (IL-1beta, IL-6, IL-10, IL-12 and TNF-alpha). Our results demonstrated that the alkylated-chitosan/DNA nanoparticles at the concentration of 20 microg/ml DNA content had no significant impact on the production of cytokines and phagocytic activity of the macrophages as compared with the unmodified chitosan/DNA nanoparticles and negative control even after 24 h co-incubation. It suggested that the modification of chitosan with alkyl group should not have negative impact on the function of the macrophages.

Abstract
The aim of this study is to compare the survival time and quality of life (QOL) of patients who have received different treatment for tracheoesophageal/bronchoesophageal fistula. Between January 2003 and December 2007, 35 patients with malignant tracheoesophageal/bronchoesophageal fistula were recorded as the control group, gastrostomy group, and stenting group, respectively, according to the treatments they chose. Two weeks after the treatment, European Organization for Research and Treatment of Cancer Quality of Life Core 30 Questionnaire (QLQ-C30), Quality of Life Questionnaire-esophageal module (QLQ-OES18), and a respiratory symptom-related QOL index are employed to assess QOL of these patients. There is no significant difference in survival time and constituent ratio of death reason among groups. Except for eight patients who died within 2 weeks after the treatment, all other 27 patients returned back the questionnaires. As compared to the control group, patients in the gastrostomy group gained a low score in emotional function and financial situation, while patients in the stenting group had lower scores in financial problems and seven respiratory and eating-related symptoms. In contrast with the gastrostomy group, patients in stenting group had higher scores in emotional and social functions, and lower scores in six respiratory and eating-related symptoms. With patients' QOL considered, the self-expandable coated stenting should be the first choice of therapy for malignant tracheoesophageal/bronchoesophageal fistula, whereas gastrostomy should be kept from use.
