Abstract
BACKGROUND With the ongoing worldwide coronavirus disease 2019 (COVID-19) pandemic, an increasing number of viral variants are being identified, which poses a challenge for nucleic acid-based diagnostic tests. Rapid tests, such as real-time reverse transcription-polymerase chain reaction (rRT-PCR), play an important role in monitoring COVID-19 infection and controlling its spread. However, the changes in the genotypes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants may result in decreased sensitivity of the rRT-PCR assay and it is necessary to monitor the mutations in primers and probes of SARS-CoV-2 detection over time. METHODS We developed two rRT-PCR assays to detect the RNA-dependent RNA polymerase (RdRp) and nucleocapsid (N) genes of SARS-CoV-2. We evaluated these assays together with our previously published assays targeting the ORF1ab and N genes for the detection and confirmation of SARS-CoV-2 and its variants of concern (VOCs). In addition, we also developed two rRT-PCR assays (S484K and S501Y) targeting the spike gene, which when combined with the open reading frames (ORF)1ab assay, respectively, to form duplex rRT-PCR assays, were able to detect SARS-CoV-2 VOCs (lineages B.1.351 and B.1.1.7). RESULTS Using a SARS-CoV-2 stock with predetermined genomic copies as a standard, the detection limit of both assays targeting RdRp and N was five copies/reaction. Furthermore, no cross-reactions with six others human CoVs (229E, OC43, NL63, HKU1, severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus) were observed using these assays. In addition, the S484K and S501Y assays were combined with the ORF1ab assay, respectively. CONCLUSIONS Four rRT-PCR assays (RdRp, N, S484K, and S501Y) were used to detect SARS-CoV-2 variants, and these assays were shown to be effective in screening for multiple virus strains.

Abstract
Objective: To analyze and discuss the psychological needs of family members of critically ill burn inpatients in semi-closed wards and their related influence factors. Methods: A cross-sectional survey was conducted among the 82 burn patients, who met the inclusion criteria and were admitted to the Department of Burns and Plastic Surgery of Ruijin Hospital of Shanghai Jiao Tong University School of Medicine from October 2018 to April 2019, and their family members. A general condition questionnaire of 15 indexes was applied to investigate the general data of burn patients and their family members including cause of burn, gender, age, total burn area, burn depth, burn severity, burn site, and type of medical insurance of patients, kinship with the patients, gender, age, experience of accompanying in intensive care isolation wards, occupation, education level, and monthly income of their family members. The Critical Care Family Needs Inventory (CCFNI) was used to assess each item, each factor, and total scores of the family members of patients including 5 factors and 45 items such as support scale (SS), comfort scale (CS), information scale (IS), proximity scale (PS), assurance scale (AS). CCFNI was used to assess the total scores of patients and their family members after classification according to the general data, the data were statistically analyzed with one-way analysis of variance or independent sample t test. Indicators with statistical significance in the above analysis were selected for multiple linear regression analysis to screen the independent influence factors of psychological needs of patients' family members. CCFNI was used to assess each dimension scores of patients and their family members after classification according to the aforementioned selected independent influence factors including age and burn area of patients, gender, educational level, and experience of accompanying in intensive care isolation wards of their family members, and the data were statistically analyzed with one-way analysis of variance or independent sample t test. Results: A total of 82 questionnaires were sent out in this study, and 80 were effectively received, with s a recovery rate of 97.6%. In 80 patients, there were 45 males and 35 females; 35 cases (43.75%) were ≤14 years; most of the patients had flame and thermal burns; 33 patients (41.25%), 21 patients (26.25%), and 26 patients (32.50%) had moderate, severe, and extremely severe burns, respectively; and only 3 patients (3.75%) had no health insurance. In 80 family members of patients, 34 (42.50%) were males and 46 (57.50%) were females; 62.50% in the family members of patients were concentrated between 18 and 45 years old; and 12 family members of patients had experience of accompanying in intensive care isolation wards, accounting for 15.00%. The total CCFNI score of the family members was (141±14) points, and the scores of AS, PS, IS, CS, and SS were (3.77±0.23), (3.43±0.37), (3.53±0.34), (2.50±0.59), and (2.69±0.45) points, respectively. The top five items of the psychological needs of family members of patients were concentrated in three factors (AS, PS, and IS), and the item "ensuring that patients receive the best treatment" ranked the first, with a score of (3.99±0.11) points. There were significant differences on the CCFNI total scores of patients with different age, total burns area, and severity of burns and of their family members with different gender, education level, and whether or not experience of accompanying in intensive care isolation unit (F=4.378, 5.481, 5.913, t=4.027, 14.339, 7.265, P<0.05 or P<0.01). Multiple linear regression analysis showed that the patient's age (≤14, 15-45 years) and total burn area (11%-30%, 31%-49%, ≥50% TBSA) and the patient's family members' gender, educational level, experience of accompanying in intensive care isolation unit could affect the psychological needs of family members of patients (t=3.133, 2.260, 2.297, 2.433, 3.015, 2.200, 2.102, 2.463, P<0.05 or P<0.01). There was statistically significant difference in AS score of the patients' family members with different age (F=4.390, P<0.05). There were significant differences in both IS and AS scores of the patients' family members of patients with different burn area (F=5.042, 3.131, P<0.05 or P<0.01). The AS score of the patients' family members with experience of accompanying in intensive care isolation unit was significantly lower than those without (t=-1.040, P<0.05). The SS score of the patients' family members with college education or above was significantly higher than those with high school (technical secondary school) or below (t=0.657, P<0.05). The IS score of the patients' family members with college education or above was significantly lower than those with high school (technical secondary school) or below (t=-1.438, P<0.05). The SS score of male family members of patients was significantly lower than those of female patients (t=4.149, P<0.05). Conclusions: The family members of burn patients in semi-closed ward have the most urgent need to ensure the patients receive the best treatment. Patients' age, total burn area, and their family members' gender, education level, experience of accompanying in intensive care isolation unit are the main factors affecting the psychological needs of family members of patients.

Abstract
BACKGROUND The significant morbidity and mortality resulted from the infection of a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) call for urgent development of effective and safe vaccines. We report the immunogenicity and safety of an inactivated SARS-CoV-2 vaccine, KCONVAC, in healthy adults. METHODS Phase 1 and phase 2 randomized, double-blind, and placebo-controlled trials of KCONVAC were conducted in healthy Chinese adults aged 18 to 59 years. The participants in the phase 1 trial were randomized to receive two doses, one each on Days 0 and 14, of either KCONVAC (5 or 10 μg/dose) or placebo. The participants in the phase 2 trial were randomized to receive either KCONVAC (at 5 or 10 μg/dose) or placebo on Days 0 and 14 (0/14 regimen) or Days 0 and 28 (0/28 regimen). In the phase 1 trial, the primary safety endpoint was the proportion of participants experiencing adverse reactions/events within 28 days following the administration of each dose. In the phase 2 trial, the primary immunogenicity endpoints were neutralization antibody seroconversion and titer and anti-receptor-binding domain immunoglobulin G seroconversion at 28 days after the second dose. RESULTS In the phase 1 trial, 60 participants were enrolled and received at least one dose of 5-μg vaccine (n = 24), 10-μg vaccine (n = 24), or placebo (n = 12). In the phase 2 trial, 500 participants were enrolled and received at least one dose of 5-μg vaccine (n = 100 for 0/14 or 0/28 regimens), 10-μg vaccine (n = 100 for each regimen), or placebo (n = 50 for each regimen). In the phase 1 trial, 13 (54%), 11 (46%), and seven (7/12) participants reported at least one adverse event (AE) after receiving 5-, 10-μg vaccine, or placebo, respectively. In the phase 2 trial, 16 (16%), 19 (19%), and nine (18%) 0/14-regimen participants reported at least one AE after receiving 5-, 10-μg vaccine, or placebo, respectively. Similar AE incidences were observed in the three 0/28-regimen treatment groups. No AEs with an intensity of grade 3+ were reported, expect for one vaccine-unrelated serious AE (foot fracture) reported in the phase 1 trial. KCONVAC induced significant antibody responses; 0/28 regimen showed a higher immune responses than that did 0/14 regimen after receiving two vaccine doses. CONCLUSIONS Both doses of KCONVAC are well tolerated and able to induce robust immune responses in healthy adults. These results support testing 5-μg vaccine in the 0/28 regimen in an upcoming phase 3 efficacy trial.

Abstract
Objective: This study aimed to investigate the correlations between the different phenotypes of the uridine diphosphate glucuronyl transferase (UGT) 1A1 gene and the treatment of advanced colorectal cancer with the FOLFIRI regimen. Materials and Methods: A total of 240 advanced colorectal cancer patients with stage IV colon cancer or recurrence after radical surgery between January 2014 and December 2018 were included in a retrospective study. All participants were treated with the FOLFIRI regimen until the disease progressed or an intolerable level of toxicity occurred. Results: In this study, three phenotypes of the UGT1A1 gene promoter were found: the homozygous wild type (TA6/6 type, 78.3%), the heterozygous mutant type (TA6/7 type, 19.6%), and the homozygous mutant type (TA7/7 type, 2.1%). Compared with TA6/7 and TA6/6, the risk of nonresponse to FOLFIRI chemotherapy increased by 16%, but the difference was not significant. The risk of death increased by 24%, and there was no significant difference. There was a risk of hematologic and nonhematologic adverse reactions occurring in TA6/7 and TA6/6, and the total risk of adverse reactions increased by 9.3773 times among patients with more than two metastatic organs. Compared with patients with TA6/6, the risk of toxic side-effects increased by 42.8066 times (p = 0.0259) for patients with TA6/7. Among patients who received FOLFIRI chemotherapy for more than four cycles, the proportion with TA6/7 was greater than that with TA6/6. Compared with those with TA6/6, patients with TA6/7 showed a higher risk of hematologic toxicity (22.3246 times, p = 0.0035). Conclusion: The TA6/7 in patients with advanced colorectal cancer had more than two metastatic organs, and received FOLFIRI chemotherapy for more than four cycles compared with TA6/6 patients. Furthermore, the risk of hematologic and nonhematologic adverse reactions significantly increased, and the risk of digestive-tract and hematologic toxicity was more significant.

The Effect of the Prognostic Nutritional Index on the Toxic Side Effects of Radiochemotherapy and Prognosis After Radical Surgery for Gastric Cancer. Cancer Manag Res 2021; 13:3385-3392.

Abstract
OBJECTIVE A retrospective analysis was conducted to investigate the effect of the preoperative prognostic nutritional index (PNI) on the severity of toxic side effects of radiochemotherapy and the survival prognosis of patients with gastric cancer to guide the clinical nutritional support for patients with gastric cancer. METHODS Data of 191 patients with gastric cancer in the Department of Gastrointestinal Surgery of Guizhou Cancer Hospital and the Affiliated Hospital of Guizhou Medical University between January 2008 and December 2018 were analyzed retrospectively. Patients were allocated to the high PNI group (with PNI ≥47.7) and the low PNI group (with PNI <47.7) according to the PNI cutoff value, and the incidence of severe toxic side effects of radiochemotherapy and the overall survival time were compared between the high PNI group and low PNI group. In addition, prognostic factor analysis was performed. RESULTS The severe hematologic side effects of radiochemotherapy and shorter postoperative survival time were more likely to occur in the low PNI group than in the high PNI group. The multifactor analysis showed that TNM stage (p = 0.000) and PNI (p = 0.001) were the independent risk factors for the overall postoperative survival time in patients with gastric cancer. CONCLUSION Preoperative PNI might predict the severity of hematologic toxic side effects of adjuvant chemotherapy/radiochemotherapy in patients with gastric cancer after surgery. Patients in the low PNI group were more likely to have severe hematologic toxic side effects, and therefore a low PNI might be one of the important factors affecting the prognosis of gastric cancer.

Abstract
The studies on infectiousness of person infected with SARS-CoV-2 at different stages of illness are an important basis for making effective prevention and control measures such as investigating the infectious source, determining the scope of close contacts and the timing of case isolation. This review discusses the infectiousness of cases infected with SARS-CoV-2 in the incubation period, symptomatic period and convalescent period by reviewing national and international literatures, technical and professional guidelines. Existing researches suggest that the infectious viruses could be isolated at the end of the incubation period as well as since illness onset, and viral load in upper respiratory tract swabs reached the peak on day 4-6 after illness onset and thereafter began to decline, implying the infectiousness was relatively strong at the end of incubation period and within one week after illness onset. Although there were a few cases who tested positive for SARS-CoV-2 after recovery, no evidence was found to indicate these cases can cause the transmission.

Abstract
Objective: To study the effects on learning and memory, mitochondrial energy metabolism and ATPase activity of hippocampus in mice with subacute exposure to n-hexane. Methods: The SPF 40 Kunming mice were randomly divided into low, middle and high dose groups and control groups according to different dosages. Each group consisted of 10 mice. The mice were given n-hexane by gavage, the mice in the low, middle and high dose groups were given 0.2 ml/d of n-hexane at concentrations of 500, 1000 and 2000 mg/kg respectively, while the mice in the control group were given 0.2 ml/d of cooking oil once a day for 28 days. The y-type maze test, the activity of ATP Enzyme, mitochondrial respiratory chain enzyme complex Ⅰ-IV, the mrna of mitochondrial fusion gene (MFn1, Mfn2) and fission gene (FIs1) in brain tissues were performed. Results: Except for the wrong reaction times of low-dose exposure group in the first test, there existed significantly different in the first and second Y-maze tests in exposure groups and control group (P<0.05) ; in low, middle and high-dose group, the Na(+)-K(+)-ATPase activities were (8.27±2.65) , (5.38±1.55) , (3.55±1.69) μmol/gprot/h, and Ca(2+)-Mg(2+)-ATPase activities were (10.32±2.96) , (7.19±1.94) and (4.49±1.33) μmol/gprot/h, respectively. Compared with those in control group, the activities of Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase decreased significantly in middle-dose group and high-dose group (P<0.05) . Compared with those in control group, the activities of mitochondrial respiratory chain enzyme complex I-IV in each dose group were significantly decreased (P<0.05) . The expressions of Mfn1mRNA and Mfn2mRNA in each dose group was significantly lower than those in control group (P<0.05) . Conclusion: Subacute exposure to n-hexane can result in the decrease of activities of mitochondrial respiratory chain enzyme complex in hippocampus of mice, which may lead to the disorder of mitochondrial energy metabolism by the decrease of ATPase activity and the imbalance of mitochondrial fusion-division, which must be one of the mechanisms of impairment of learning and memory of mice induced by n-hexane.

Abstract
Objective: To compare the long-term oncological outcomes between laparoscopic and abdominal surgery in stage Ⅰa1 (lymph-vascular space invasion-positive, LVSI+)- Ⅰb1 cervical cancer patients with different tumor sizes. Methods: Based on the Big Database of Clinical Diagnosis and Treatment of Cervical Cancer in China (1538 project database), patients with stage Ⅰa1 (LVSI+)-Ⅰb1 cervical cancer who treated by laparoscopic or abdominal surgery were included. The 5-year overall survival (OS) and 5-year disease-free survival (DFS) between the two surgical approaches were compared under 1∶1 propensity score matching (PSM) in different tumor diameter stratification. Results: (1) A total of 4 891 patients with stage Ⅰa1 (LVSI+)-Ⅰb1 cervical cancer who underwent laparoscopy or laparotomy from January 1, 2009 to December 31, 2016 were included in the 1538 project database. Among them, 1 926 cases in the laparoscopic group and 2 965 cases in the abdominal group. There were no difference in 5-year OS and 5-year DFS between the two groups before matching. Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS (HR=1.367, 95%CI: 1.105-1.690, P=0.004). After 1∶1 PSM matching, 1 864 patients were included in each group, and there was no difference in 5-year OS between the two groups (94.1% vs 95.4%, P=0.151). While, the inferior 5-year DFS was observed in the laparoscopic group (89.0% vs 92.3%, P=0.004). And the laparoscopic surgery was associated with lower 5-year DFS (HR=1.420, 95%CI: 1.109-1.818, P=0.006). (2) In stratification analysis of different tumor sizes, and there were no difference in 5-year OS and 5-year DFS between the laparoscopic group and abdominal group in tumor size ≤1 cm, >1-2 cm and >2-3 cm stratification (all P>0.05). Cox multivariate analysis showed that laparoscopic surgery were not related to 5-year OS and 5-year DFS (P>0.05). In the stratification of tumor size >3-4 cm, there was no difference in 5-year OS between the two groups (P>0.05). The 5-year DFS in the laparoscopic group was worse than that in the abdominal group (75.7% vs 85.8%, P=0.025). Cox multivariate analysis suggested that laparoscopic surgery was associated with lower 5-year DFS (HR=1.705, 95%CI: 1.088-2.674, P=0.020). Conclusions: For patients with stage Ⅰa1 (LVSI+)-Ⅰb1 cervical cancer, laparoscopic surgery is associated with lower 5-year DFS, and the adverse effect of laparoscopic surgery on oncology prognosis is mainly reflected in patients with tumor size >3-4 cm. For patients with tumor sizes ≤1 cm, >1-2 cm and >2-3 cm, there are no difference in oncological prognosis between the two surgical approaches.

Abstract
Small nucleolar RNA host genes (SNHGs) as a subset of long noncoding RNAs (lncRNAs) have critical roles in the pathogenesis of multiple malignancies, however, the role and molecular mechanisms of lncRNA SNHG8 in osteosarcoma (OS) remain unclear. In the present study, the correlation of SNHG8 or miR-542-3p with clinicopathological elements and prognosis in OS patents was estimated by TCGA cohort. Cell viability and invasion were assessed by MTT and Transwell assays. The interplay between SNHG8 and miR-542-3p was affirmed by a luciferase report assay. The effects of SNHG8 on miR-542-3p expression were examined in MG-63 and SW-1353 cells by qRT-PCR analysis. The results showed that incremental expression of SNHG8 or reduced expression of miR-542-3p was related to poor survival and tumor recurrence in OS patients. Overexpressing SNHG8 accelerated the growth and invasion of MG-63 cells, but silencing SNHG8 harbored an opposite effect in SW-1353 cells. Additionally, SNHG8 could negatively regulate miR-542-3p expression and bind with miR-542-3p, which attenuated SNHG8 induced cell proliferation. Taken together, these findings indicate that lncRNA SNHG8 promotes the proliferation of OS cells by downregulating miR-542-3p.

Abstract
Pollinating butterflies are an important asset to agriculture, which still depends on wild resources. Yunnan Province in Southwest China is a region with typical montane agriculture, but this resource is poorly investigated. From literature reference and specimen examination, the present study identified 554 species of pollinating butterflies (50.8% of the total butterflies) from Yunnan, with family Nymphalidae possessing the least number of pollinators (80 species, 16.0%), while the remaining four families are pollinator-rich (>73%). Tropical lowlands and mountain-valley areas possess higher species richness than those with plain terrains. The species richness of pollinating butterflies in Yunnan does not simply decline with the increase of latitude, nor is significantly different between West and East Yunnan. Zonation of pollinating butterflies using the parsimony analysis of endemicity (PAE) identified nine distribution zones and ten subzones. Most areas of endemism (AOE) are found in lowlands or mountain-valley areas, complexity of terrains, climates, and vegetation types are believed to be the main causes of such endemicity. The potential pollinating service of these butterflies could be great to montane agriculture with expanding areas of cash crops and fruit horticulture. Conservation strategies for pollinating butterflies may consist of preserving habitats and establishing butterfly-friendly agriculture based on local traditions.

Abstract
This study aims to investigate the role of PM2.5 exposure in inducing apoptosis of alveolar epithelial cells and thereafter emphysema in mice, and the underlying mechanism. PM2.5 exposure model in mice was constructed. Lung tissues were harvested from healthy mice and model mice for hematoxylin and eosin (H&E) staining. Protein levels of Forkhead box O3 (FOXO3A) and BIM in lung tissues were detected by Western blot. Subsequently, A549 cells were induced with increased doses of PM2.5, followed by determination of relative levels of FOXO3A, BIM (Bcl-2 interacting mediator of cell death) and clv-caspase3. Apoptosis in PM2.5-exposed A549 cells was assessed. Chromatin immunoprecipitation (ChIP) assay was conducted to uncover the interaction between FOXO3A and BIM. Finally, regulatory effects of FOXO3A/BIM on apoptosis of A549 cells were determined. PM2.5 exposure resulted in expansion of alveolar spatial structure and decline of lung function, thus leading to emphysema in mice. Protein levels of FOXO3A and BIM were markedly upregulated in lungs of model mice. Relative levels of FOXO3A, BIM and clv-caspase3 were enhanced in PM2.5 -exposed A549 cells, which were reversed by transfection of si-FOXO3A. ChIP assay confirmed that FOXO3A was able to regulate BIM transcription through binding its promoter regions. Importantly, regulatory effects of FOXO3A on apoptosis of PM2.5 -exposed A549 cells were partially reversed by overexpression of BIM. PM2.5 exposure leads to upregulation of FOXO3A, which triggers BIM transcription, thus inducing apoptosis of alveolar epithelial cells and emphysema in mice.

Abstract
Objective: To obtain the prevalence laryngopharyngeal reflux disease (LPRD), anxiety and depression in otorhinolaryngology outpatients and to explore the role of mental and psychological factors (anxiety and depression) in their pathogenesis. Methods: A questionnaire survey of reflux symptom index(RSI) scale and hospital anxiety and depression (HAD) scale were used to report 1 111 cases of outpatients in Department of Otorhinolaryngology Head and Neck Surgery, Peking University People's Hospital, from July 2017 to June 2018 (486 males, 625 females, age of 18-96 years old, median age of 38[30,53] years old) and to obtain the prevalence of LPRD, anxiety and depression. RSI-positive patients were selected in the case group, and RSI-negative patients were selected in the control group. The differences in HAD scores between the two groups were compared, and the risk factors of laryngopharyngeal reflux were analyzed. Statistical analysis was performed using SPSS 20.0 software. Results: There were 151 cases in the case group and 960 cases in the control group. The prevalence of LPRD was 13.59% (151/1 111).There was no significant difference in the prevalence of LPRD between different genders (P>0.05). The prevalence rate was the highest in the 18-40 age group, and the difference in the prevalence of all age groups (18~ 40 years old; 41-65 years old; >65 years old) was statistically significant (P<0.05). The prevalence of LPRD among smokers and non-drinkers was higher than that of non-smokers and non-drinkers and the prevalence of the two groups was statistically significant (P<0.05). The most common symptoms of the RSI scale were pharyngeal foreign body sensation (92.72%,140/151), persistent clearing throat (88.74%,124/151), excessive sputum or nasal reflux (82.12%, 124/151). There were significant statistical differences between the two groups (P<0.05). Ninty-one patients with anxiety, the prevalence was 8.19%(91/1 111); 76 patients with depression, the prevalence was 6.84%(76/1 111).Among the LPRD patients, the hospital anxiety scale scored 29.14% (44/151), and the hospital depression scale scored 17.22% (26/151). The scores of anxiety symptoms and depressive symptoms in the LPRD group were higher than those in the non-LPRD group. The above scores were statistically significant (P<0.05). Logistic regression analysis showed that smoking, anxiety and symptoms of gastroesophageal reflux disease were independent risk factors for laryngopharyngeal reflux. Conclusions: The prevalences of LPRD, anxiety and depression in the otorhinolaryngology clinic are 13.59%, 8.19% and 6.84%, respectively. Among patients with laryngopharyngeal reflux, the prevalence of anxiety is 29.14%, and the prevalence of depression is 17.22%. Age, smoking, drinking, alcohol consumption, education level, course of disease, symptoms of gastroesophageal reflux disease, pharyngeal foreign body sensation, etc. are related to LPRD. Mental factors (anxiety and depression) may play a role in LPRD. Smoking, anxiety symptoms and symptoms of gastroesophageal reflux disease are closely related to the incidence of LPRD.

Abstract
Objective: To investigate the feasibility, efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) in the individualized treatment of patients with refractory ascites and variceal hemorrhage caused by portal hypertension. Methods: Prospective study of clinical data of 47 patients with portal hypertension and refractory ascites and variceal bleeding admitted to the Affiliated Hospital of Xuzhou Medical University from August 2017 to December 2018, 26 males and 21 females, aged 23-75 (52±14) years old. The Viabahn stent was used to control the diameter of the shunt and the preoperative interval of PPG after individualized TIPS was determined according to the preoperative liver function Child-Pugh classification. The PPG of the Child A and B patients was <10 mm Hg (1 mmHg=0.133 kPa), Child-Pugh C grade patients with postoperative PPG interval values of 12 to 15 mmHg. The success rate, hemostasis rate, ascites remission rate, and complication rate were recorded. Results: Forty-seven patients were with a success rate of 100%, and there was no surgically related fatal complications. The portal pressure gradients of patients with Child-Pugh A, B and Child-Pugh C were reduced from preoperative (22.5±5.4), (24.4±2.6) mm Hg to postoperative (8.8±2.5), (13.2±1.1) mm Hg (all P<0.05). All the patients were followed up for 6 to 24 months, with a median follow-up of 13 months. The success rate of hemostasis in patients with upper gastrointestinal bleeding was 93.5% (29/31), the remission rate of patients with refractory ascites was 14/16, the postoperative rebleeding rate was 6.5% (2/31), the incidence of hepatic encephalopathy was 8.5% (4/47), and the shunt disorder was 2.1% (1/47). Conclusion: The use of Viabahn stent for individualized TIPS in the treatment of portal hypertension with refractory ascites and variceal hemorrhage is feasible, and the clinical efficacy is affirmative, which can reduce the incidence of postoperative hepatic encephalopathy and shunt dysfunction.

Abstract
Objective: To establish a New Zealand rabbit animal model of laryngopharyngeal reflux disease (LPRD) using esophageal balloon together with metal internal stent dilation and to investigate the changes of mucosa. Methods: 20 New Zealand rabbits were randomly divided into experimental group and control group, with 10 in each group. Balloon dilatation and metal internal stent dilation were carried out in experimental group to reproduce the animal model of LPRD.The middle of balloon was placed at the lower esophageal sphincter (LES) while the stent was placed at the upper esophageal sphincter (UES). The guide wire was placed in the control group, but the balloon was not expanded and the stent was not placed. The general condition, pH value of hypopharynx, laryngeal histopathology and changes of pepsin content of New Zealand rabbits were observed regularly. The difference between experimental group and control group was compared. Results: The 24-hour Dx-pH monitoring results showed that the number of reflux episodes(20.0[9.5, 35.0], 13.0[6.5, 22.0]), and the percent time below pH 5.5 (1.36%[0.60%, 4.57%], 1.36%[0.43%, 2.77%]) in the experimental group at the 2nd and 4th week were significantly different from those in the control group (0[0,3.0], 1.0[0.5, 3.8]; 0[0, 0.01%], 0[0, 0], respectively, all P<0.01), suggesting that the experimental group New Zealand rabbits developed LPRD. Compared with the control group under microscope, lymphocytes infiltration and submucosal gland hyperplasia increased in the mucosa of the throat of the experimental group. The results of pepsin immunohistochemical staining between the two groups were statistically significant (P=0.014). Conclusion: The use of balloon dilatation of the LES combined with metal stent dilatation of the UES can successfully establish a laryngopharyngeal reflux model, and lesions in the throat tissue can be observed.

Abstract
BACKGROUND The malnutrition-inflammation score (MIS) is a nutritional scoring system that has been validated in chronic kidney disease (CKD) stages III-V, especially in dialysis patients. We aimed to test whether the MIS changed in the early stages of CKD and whether it was associated with anthropometry and body composition measurements (BCMs) in patients with CKD. METHODS This was a cross-sectional study conducted in the Nephrology Department. A total of 144 patients with CKD were included in the study between May 2017 and December 2017. The MIS was calculated without computing the dialysis vintage in the scoring. Body composition was measured using a portable whole-body bioimpedance spectroscopy device. Anthropometric, laboratory, and other body composition parameters were recorded. RESULTS The MIS was increased in patients with CKD. It was negatively correlated with body mass index (BMI), mid-arm muscle circumference (MAMC), handgrip strength, lean tissue index (LTI), fat tissue index (FTI), phase angle (PA), and hemoglobin and albumin concentrations, and it was positively correlated with sex, overhydration, urinary protein excretion and IL-6. A high MIS was significantly correlated with a low LTI (r=-0.274; P=0.001), low FTI (r=-0.179; P=0.032), overhydration (r=0.457; P<0.001) and low PA (r=-0.475; P<0.001). A rather strong correlation was observed between the PA and the MIS. In the multivariate regressions, after adjusting for age, sex, presence of diabetes, handgrip strength, BMI, overhydration, glomerular filtration rate, albumin and IL-6 concentrations, these relationships did not diminish. CONCLUSIONS The MIS was strongly linked with indicators of nutrition. As a simple and practical tool for assessing nutritional status, the MIS should be calculated in the early stages of CKD.

Abstract
Objective: To analyze the 13 years trend in proportion, risks factors and clinicopathological characteristics of young women with stage Ⅰa2 to Ⅱa2 cervical cancer by using multi-center data of cervical cancer in China. Methods: The clinicopathological data of 46 313 patients with cervical cancer treated from 37 hospitals in China were obtained from January 2004 to December 2016. Using clinical and pathologic data, each patient's stage was reclassified by the 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system. A total of 19 041 patients were selected according to the following criteria: FIGO stage Ⅰa2 to Ⅱa2, underwent type B or C radical hysterectomy and pelvic lymphadenectomy. All the patients were divided into two groups: the study group of 1 888 patients aged 35 years or younger and the control group of 17 153 patients aged over 35 years. The 13 years trend in proportion of young women with stage Ⅰa2 to Ⅱa2 cervical cancer, risks factors and clinicopathological characteristics of two groups were retrospectively analyzed. Results: (1) The total number of hospitalized patients with stage Ⅰa2 to Ⅱa2 cervical cancer increased annually. However, a downward trend of patients aged 35 years or younger was observed (P<0.01) . The constituent ratio of patients aged 35 years or younger was significantly greater during 2004-2010 than that during 2011-2016 [12.6% (820/6 484) and 8.5% (1 068/12 557) , respectively; χ(2)=82.101, P<0.01]. (2) Compared with patients aged over 35 years, patients aged 35 years or younger had an earlier age at menarche, a later age at marriage, lesser gravida and parity (all P<0.01). The positive rate of high-risk HPV infection was not statistically different between two groups (all P>0.05). (3) The proportions of stage Ⅰ, exophytic type and non-squamous histological type in patients aged 35 years or younger were clearly higher than those in patients aged over 35 years (83.4% vs 68.5%, P<0.01; 63.2% vs 56.2%, P<0.01; 13.9% vs 12.0%, P<0.05, respectively). Whereas the poor differentiation ratios of the two groups had no statistical significance (P>0.05). (4) As for the postoperative pathological risk factors, the rate of surgical margin involvement in patients aged 35 years or younger was lower than that aged over 35 years (1.1% vs 1.8%, P<0.05), and the rate of depth of stromal invasion >1/2 in patients aged 35 years or younger was lower than that in patients aged over 35 years (40.1% vs 50.9%, P<0.01). In addition, there were no significant difference in parametrial margin involvement, tumor size and lymph vascular space invasion between two groups (all P>0.05). Conclusions: The trend in proportion among hospitalized patients for stage Ⅰa2 to Ⅱa2 cervical cancer in young women is decreasing yearly. Compared with cervical cancer in middle-aged and elderly women, cervical cancer in young women have an earlier age at menarche, a higher proportion of stage Ⅰ patients and non-squamous histological type. In terms of the postoperative pathological risk factors, the rate of surgical margin involvement and depth of stromal invasion >1/2 in young women with cervical cancer are lower than in middle-aged and elderly women.

Abstract
Abstract
Background: Lung cancer is the leading cause of cancer death in Taiwan and worldwide and non-small cell lung cancers (NSCLCs) account for more than 85% of lung cancers. Pemetrexed is approved for several steps of nonsquamous NSCLC therapy but drug resistance often occurs in long-term treatment. Cancer stem cells (CSCs) are considered as the rare subpopulation of cancer cells with the features of tumor initiation, drug resistance, and metastatic capability. The signaling pathway and potential targets contribute to the maintenance of pemetrexed-resistant cancer stem cell remain unknown.
Methods: To investigate the mechanism of pemetrexed resistance in lung cancers, the pemetrexed-resistant A549 cells were established (A400). The sphere-formation assay, western blot analysis and real-time qPCR were employed to identify cancer stem cells and study their properties.
Result: We first discovered that the pemetrexed-resistant A549 cells (called A400) contained more CSC activity than the parental A549 cells including the increased number of tumorspheres and the upregulation of BMI1, c-Myc, Sox2 and p-IGF1Rtyr1165/1166 expression. The treatment of PTC-209, a BMI1 inhibitor, displayed a greater inhibitory effect in cell proliferation in A400 than A549 cells and it suppressed tumorsphere formation capability of A400 cells. In addition, PTC-209 treatment downregulated the expression of IGF1R, p-IGF1Rtyr1165/1166, and Sp1, a positive regulatory transcriptional factor in IGF1R expression, in A400 cells. We also found that Sp1 was increased in A400 when compared to parental A549 cells. With the treatment of Sp1 inhibitor in A400 cells, the expression of IGF1R was suppressed without changing BMI1 level. Finally, we examined the therapeutic effect of BMI1 inhibition in vivo and resulted found that intraperitoneal administration of PTC-209 enhanced the pemetrexed efficacy in NOD/SCID mice harboring A400 xenograft tumors.
Conclusion: Our data reveal that BMI1/Sp1/IGF1R pathway is upregulated in pemetrexed resistant NSCLCs and targeting BMI1 could be a therapeutic strategy in NSCLCs when pemetrexed resistance occurs.

Abstract
Purpose: The prevalence of depression and the relationship between depression and kidney function and health-related quality of life (HRQOL) are not well understood in elderly patients with predialysis chronic kidney disease (CKD). This study aimed to evaluate the prevalence of depression and the association between depression and kidney function and HRQOL. Patients and methods: In this cross-sectional study, 1079 elderly participants with CKD were recruited at 32 clinical centers located within 26 cities throughout 24 provinces in China. Demographic information and laboratory analyses were collected. Symptoms of depression were assessed using the 15-item Geriatric Depression Scale (GDS-15). HRQOL was evaluated using the Kidney Disease Quality of Life-36 (KDQOL-36) instrument. Results: The prevalence of depression was 23.0%. The estimated glomerular filtration rate (eGFR) was negatively correlated with the GDS score whether it was treated as a categorical variable (r=-0.097, P=0.001) or as a continuous variable (r=-0.100, P=0.001). Marital status, education level, history of CVD and diabetes, CKD stage and proteinuria confirmed to be independent and significant predictors of depression in patients with CKD. Compared with CKD 1-2 patients, we observed an increase of 0.541 and 4.171 in the odds for developing depression in patients CKD 4 (odds ratio [OR] =1.541; P=0.031) and CKD 5 (odds ratio [OR] =5.171; P<0.001), respectively. We observed negative and significant correlations with the GDS score for the following components: PCS (r=-0.370, P<0.001), MCS (r=-0.412, P<0.001), burden of kidney disease (r=-0.403, P<0.001), symptoms and problems of kidney disease (r=-0.360, P<0.001) and effects of kidney disease (r=-0.355, P<0.001). Depression was an independent and significant predictor of all the subcomponents of the HRQOL. Conclusions: The prevalence of depression in elderly patients with CKD was high and was negatively correlated with kidney function. Depression had a major negative impact on HRQOL.

Abstract
BACKGROUND Because of advances in medical treatment, the survival of cancer patients is prolonged. In line with the prolonged survival time of cancer the incidence of second primary cancer has increased. There is currently no effective way to prevent the occurrence of secondary primary cancer (SPC). OBJECTIVES The aim of this study is to evaluate whether Chinese Herbal Medicine (CHM) is correlated with reduced occurrence of second primary cancer (SPC) of head and neck (H&N) in patients with esophageal cancer (EC). METHOD We identified 15,546 patients who were diagnosed with esophageal cancer between Jan 1, 2000, and Dec 31, 2010. The patients with H&N cancer before receiving CHM were excluded. After the selection and matching process, both CHM and non-CHM cohorts each contained 850 individuals. We compared the cumulative incidence of SPC of H&N with or without CHM treatment in patients with EC by the Kaplan-Meier method. NodeXL is used to run a network analysis of CHM to examine the association between herbs and formulas. RESULTS Compared with non-CHM users, CHM-users showed a reduced incidence rate of SPC of H&N among the patients with EC. Reduced cumulative incidence of SPC of H&N among patients with EC was noted in the CHM cohort compared to the non-CHM cohort. The most commonly used single herbs and formulas were associated with reducing SPC occurrence. CONCLUSION We propose that CHM as an adjuvant therapy may prevent the occurrence of SPC of H&N in patients with EC.

目的 研究磷酸肌醇依赖性激酶1(PDK1)在内皮细胞向造血细胞转化阶段对造血干细胞(HSC)发生的影响。 方法 应用Vec-Cre在内皮细胞中特异性敲除PDK1基因,取对照组PDK1fl/fl、PDK1fl/+小鼠及敲除组Vec-Cre;PDK1fl/fl小鼠胚胎的主动脉-性腺-中肾区(AGM区)细胞进行集落形成实验,检测PDK1基因对造血祖细胞功能的影响;取对照组和敲除组AGM区细胞行移植实验,检测PDK1对HSC功能的影响;取对照组和敲除组AGM区细胞,通过流式细胞术检测PDK1对能够向造血转化的CD31+c-Kithigh细胞群比例、细胞周期及细胞凋亡的影响;分选对照组和敲除组AGM区CD31+c-Kithigh细胞群,通过Real-time PCR检测PDK1对内皮向造血转换相关的转录因子(RUNX1、P2-RUNX1、GATA2)的影响。 结果 PDK1敲除后,造血祖细胞形成的克隆形态变小,数目减少[敲除组CFU-GM为(24±5)个/ee,对照组为(62±1)个/ee,P=0.001];破坏了造血干细胞重建造血及多向分化的能力(敲除组移植5只,0只重建,对照组移植7只,5只重建,P=0.001);AGM区CD31+c-Kithigh比例降低[敲除组CD31+c-Kithigh比例为(0.145±0.017)%,对照组比例为(0.385±0.04)%,P=0.001];并且AGM区由内皮细胞向造血细胞转换的关键转录因子表达下降,但对CD31+c-Kithigh细胞的增殖和凋亡无明显影响。 结论 在内皮细胞中特异敲除PDK1基因,导致具有向造血转化的内皮细胞群比例降低,影响了HSC的发生,破坏了HSC重建造血的能力。

Abstract
Objective: To investigate the clinical effect of enhanced recovery after surgery (ERAS) in unilateral total knee arthroplasty (TKA). Methods: Retrospective analysis of 98 patients received unilateral TKA from September 2015 to September 2016 in the Orthopaedic Departmentof Affiliated Hospital of Logistics University of Chinese People's Armed Police Forces.Of the patients, 52 cases were treated by traditional operation (routine group) and the other 46 cases were treated with ERAS concept (ERAS group). The following data were gathered and statistically analyzed between the groups: gender, age, body mass index, preoperative hemoglobin, preoperative visual analogue scale (VAS) score, postoperative visible blood loss, postoperative hemoglobin at 24 hour after operation, blood transfusion rate, postoperative VAS score, length of hospital stay, the satisfaction rate, preoperative and 1 and 6 months postoperative evaluation with hospital for special surgery knee score (HSS), postoperative range of motion (ROM) of knees after 2 weeks, 1 month and 6 months of surgery, incidence rate of complications after surgery.Data between groups were analyzed with one-factor analysis of variance or chi-square test. Results: There was no significant difference in preoperative data between two groups.Postoperative visible blood loss of ERAS group was significantly lower than that in routine group[(224±59) vs (361±70) ml, t=4.723, P<0.01]; postoperative hemoglobin after 24 hours in ERAS group was significantly higher than that in routine group[(109±8) vs (96±10) g/L, t=-3.297, P=0.004]; blood transfusion rate of ERAS group was significantly lower than that in routine group[6.5 %(3/46) vs 46.2%(24/52), χ(2)=19.207, P<0.01]; the 12-hour and 48-hour postoperative VAS scores in ERAS groups were both significantly lower than those in routine group (t=3.708, 3.894, both P<0.05); length of hospital stay in ERAS group was significantly shorter than that in routine group[(6.8±1.2) vs (13.1±2.6) d, t=6.924, P<0.01]; HSS scores of ERAS groups at 1 month and 6 months after surgery were both significantly higher than those in routine group (t=-3.677, -3.594, both P<0.05); knees ROM in ERAS group at 2 weeks and 1 month after surgery were both significantly higher than those in routine group (t=-4.628, -4.442, both P<0.05); the rate of postoperative nausea vomiting in ERAS group was significantly lower than that in routine group[13.0%(6/46) vs 48.1%(25/52), χ(2)=13.852, P=0.002]. VAS score at 1 month after surgery, knees ROM at 6 months after surgery and the satisfaction rate were all comparable between the two groups (t=0.412, -1.026, χ(2)=3.695, all P>0.05). Conclusions: Condition of patients treated by unilateral TKA under ERAS model improves effectively during perioperative period when compared with routine treatment, patients have earlier rehabilitation and better experience in hospital and operation.
