Abstract
BACKGROUND The McKeown minimally invasive esophagectomy (McMIE) procedure has various limitations, including surgical contraindications and a high rate of postoperative pulmonary complications. A novel mediastinoscopic esophagectomy procedure was described in this study by using esophageal invagination and a transhiatal and bilateral cervical approach (EITHBC). METHODS According to the mode of operation, a total of 259 patients were divided into two groups, among which 106 underwent EITHBC and 153 underwent McMIE. The number of lymph nodes dissected, intraoperative outcomes, and postoperative outcomes were compared between the two groups of patients. RESULTS The results revealed that the average number of resected lymph node in the EITHBC group was significantly higher in the recL106 and TbL106 stations (recL106: 1.75 vs. 1.51, p = 0.016, TbL106: 1.53 vs. 1.19, p = 0.016) and significantly lower in the 107 stations (1. 74 vs. 2. 07, p < 0.001) than in the McMIE group. The intraoperative blood loss in the EITHBC group was significantly lower than that in the McMIE group (63.30 vs. 80.45 mL, p < 0.001). The incidence of postoperative pulmonary complications in the EITHBC group was lower than that in the McMIE group (14.15% vs. 27.45%, p = 0.008). The incidence of recurrent laryngeal nerve paralysis in the EITHBC group was significantly higher than that in the McMIE group (26.41% vs. 10.46%, p = 0.003). CONCLUSION Compared with the McMIE procedure, the EITHBC procedure has advantages in terms of removing the upper mediastinal lymph nodes and reducing postoperative pulmonary complications.

Abstract
INTRODUCTION Lung cancer is one of the most common cancer malignancies and the principal cause of cancer-associated deaths worldwide. Non-small cell lung cancers (NSCLCs) account for more than 80% of all lung cancer cases. Recent studies showed that the genes of the integrin alpha (α) (ITGA) subfamily play a fundamental role in various cancers. However, little is known about the expression and roles of distinct ITGA proteins in NSCLCs. METHODS Gene Expression Profiling Interactive Analysis and UALCAN (University of ALabama at Birmingham CANcer) web resources and The Cancer Genome Atlas (TCGA), ONCOMINE, cBioPortal, GeneMANIA, and Tumor Immune Estimation Resource databases were used to evaluate differential expression, correlations between the expression levels of individual genes, the prognostic value of overall survival (OS) and stage, genetic alterations, protein-protein interactions, and the immune cell infiltration of ITGAs in NSCLCs. We used R (v. 4.0.3) software to conduct gene correlation, gene enrichment, and clinical correlation of RNA sequencing data of 1016 NSCLCs from TCGA. To evaluate the expression of ITGA5/8/9/L at the expression and protein levels, qRT-PCR, immunohistochemistry (IHC), and hematoxylin and eosin (H&E) were performed, respectively. RESULTS Upregulated levels of ITGA11 messenger RNA and downregulated levels of ITGA1/3/5/7/8/9/L/M/X were observed in the NSCLC tissues. Lower expression of ITGA5/6/8/9/10/D/L was discovered to be expressively associated with advanced tumor stage or poor patient prognosis in patients with NSCLC. A high mutation rate (44%) of the ITGA family was observed in the NSCLCs. Gene Ontology functional enrichment analyses results revealed that the differentially expressed ITGAs could be involved in roles related to extracellular matrix (ECM) organization, collagen-containing ECM cellular components, and ECM structural constituent molecular functions. The results of the Kyoto Encyclopedia of Genes and Genomes analysis revealed that ITGAs may be involved in focal adhesion, ECM-receptor interaction, and amoebiasis; the expression of ITGAs was significantly correlated with the infiltration of diverse immune cells in NSCLCs. ITGA5/8/9/L was also highly correlated with PD-L1 expression. The validation results for marker gene expression in NSCLC tissues by qRT-PCR, IHC, and H&E staining indicated that the expression of ITGA5/8/9/L decreased compared with that in normal tissues. CONCLUSION As potential prognostic biomarkers in NSCLCs, ITGA5/8/9/L may fulfill important roles in regulating tumor progression and immune cell infiltration.

Abstract
Objective To understand the characteristics of genetic mutation in multiple primary lung cancer so as to guide clinical decisions in targeted therapy. Methods We analyzed a total of 265 tumors from 111 patients who underwent surgery for multiple lung cancers. Individual tumors were subjected to histological evaluation and gene mutation analysis using ABI 7500 Fluorescence quantitative PCR. Results In this study, we analyzed demographic and clinical parameters such as age, gender, smoking, alcohol consumption, pathological type, number of nodules, and other details of 111 patients with early multiple primary lung cancer. We also compared the clinicopathologic characteristics of different populations based on the gene mutation status of pulmonary nodules. Subsequently, we performed a clinicopathological analysis of all 265 pulmonary nodules from these patients. Results showed significant differences in clinicopathological features of pulmonary nodules in different genetic mutations. Conclusion This study revealed the gene mutation characteristics and clinicopathological features in early multiple primary lung cancer. We found that the gene mutation status between different nodules in patients with early multiple primary lung cancer was inconsistent in most cases. Therefore, the use of targeted therapy based on the genetic sequencing of only one nodule, is unreliable. We hope this study can be helpful in guiding clinical treatment decisions.

Abstract
Objective This study aimed to design a nomogram survival prediction by means of the figures retrieved from the Surveillance, Epidemiology, and End Results (SEER) source bank, and to predict the overall survival (OS) of patients with stage IIA non-small cell lung cancer (NSCLC) after surgery. Methods Data for 4511 patients who had been diagnosed with postoperative stage IIA NSCLC were collected from the SEER databank, while information on 528 patients was acquired from the Chongqing University Cancer Hospital for the external validation cohort. The independent risk factors that affected the prognosis were identified using a multivariate Cox proportional hazards regression model (also used to conduct a nomogram). A survival analysis between the low- and the high-risk groups was performed using the Kaplan-Meier method. Furthermore, a subgroup analysis was conducted of the two groups using the Kaplan-Meier method to determine whether the patients had received adjuvant chemotherapy. Results The following five variables were integrated into the nomogram: sex (female: HR 1.73, 95% CI 0.64-0.83), age (≥60: HR 1.61, 95% CI 1.39-1.87), differentiation grade (grade II: HR 2.19, 95% CI 1.66-2.88; grade III: HR 2.65, 95% CI 2.00-3.51; grade IV: HR 3.17, 95% CI 1.99-5.03), surgery (lobectomy: HR 0.72, 95% CI 0.59-0.86), and lymph node resection (>12: HR 0.82, 95% CI 0.70-0.96). Furthermore, the patients selected were categorized into high- and low-risk groups. The OS rate was significantly lower in the high-risk group than in the low-risk group (P < 0.001). Finally, adjuvant chemotherapy was highly correlated with OS in the high-risk set (P = 0.035); however, adjuvant chemotherapy was not related to OS in the low-risk set. Conclusion A nomogram was created as a reliable, convenient scheme that could predict OS, and it was determined that the high-risk feature patients identified by the nomogram gained benefits from adjuvant chemotherapy.

Abstract
Objective: To explore the influencing factors of cognitive impairment in patients with silicosis, and to analyze the effect of brain-derived neurotrophic factor (BDNF) on cognitive function. Methods: In March 2021, 484 silicosis patients from April 2018 to April 2020 were included in the study. The Montreal Cognitive Assessment Scale of Chinese version was used to evaluate their cognitive function, and they were divided into the cognitive impairment group (n=282) and the non cognitive impairment group (n=202) , another 30 healthy persons from body check were served as control group. The concentrations of BDNF were compared between the three groups. And the receiver operating characteristic (ROC) curve was drawed to analyze the value of BDNF in predicting cognitive impairment in silicosis patients. And the logistic regression analysis was used to explore the risk factors of cognitive impairment. Results: The incidence of cognitive impairment in silicosis patients was 58.26% (282/484) . The level of BDNF in the cognitive impairment group[ (10.32±2.11) mg/L] was significantly lower than that in the non cognitive impairment group[ (13.43±3.45) mg/L] (t=-12.27, P<0.001) . The results of ROC curve analysis showed that the area unde the curve of BDNF in predicting cognitive impairment of silicosis patients was 0.763 (95%CI: 0.613-0.874, P=0.024) , the cut off value was 10 mg/L, the sensitivity was 0.88, and the specificity was 0.84. Logistic regression analysis showed that the level of BDNF (≤10 mg/L) , age (≥65 years old) , course of disease (≥5 years) and diabetes mellitus were the risk factors of cognitive impairment in silicosis patients (OR=2.346, 95%CI: 1.654-3.103; OR=1.757, 95%CI: 1.214-1.998; OR=1.346, 95%CI: 1.112-1.564; OR=1.165, 95%CI: 1.102-1.542, P=0.001, 0.012, 0.027, 0.036) . Conclusion: BDNF may be one of the indicator to predict the risk of cognitive impairment in patients with silicosis.

Abstract
Background This study assessed the efficacy of transcervical and transhiatal esophagectomy versus thoracoscopic esophagectomy in patients with esophageal carcinoma (EC). Methods A total of 80 patients with EC were enrolled in this study, including 40 cases in the observation group that received transcervical combine transhiatal esophagectomy and the rest 40 cases of the group that underwent thoracoscopic esophagectomy. The preoperative, intraoperative, and postoperative data were analyzed between the two surgeries, regarding perioperative bleeding, the total number of dissected mediastinal lymph nodes, operative time, number of lymph nodes in the left para-recurrent laryngeal nerve (para-RLN) or the right para-RLN, time in the intensive care unit (ICU), postoperative pain score, the length of postoperative stay (LOPS), PO2/fraction of inspired oxygen (PO2/FiO2), pulmonary infection, and lymphatic metastasis. Results The operations were successfully performed in all 80 patients. The results showed that patients who underwent transcervical and transhiatal esophagectomy had shorter operations than those with transthoracic esophagectomy (200 minutes vs 235 minutes, Kruskal–Wallis test [Z] = –3.700, P < 0.001). The number of dissected mediastinal lymph nodes in the left para-RLN in the observation group was higher than in the control group (25.0% vs 2.5%, Z = 2.568, P = 0.010). The postoperative pain score day 1 (0.0% vs 17.5%, Z = –4.292, P < 0.001), postoperative pain score day 3 (12.5% vs 37.5%, Z = –3.363, P < 0.001) and 48-h PO2/FiO2 (290 minutes vs 255 minutes, Z = 3.747, P < 0.001) were significant between the two groups. The LOPS of patients with EC in the observation group was shorter than the control group (7 vs 8, Z = –2.119, P = 0.034). The number of patients receiving transcervical and transhiatal esophagectomy that developed postoperative pulmonary infections was less than the controls (chi-square [χ2] = 4.114, P = 0.043). Moreover, the transcervical and transhiatal esophagectomy was an independent protect factor for postoperative pulmonary infection (odds ratio [OR] =7.801, P = 0.037). Conclusion The transcervical and transhiatal esophagectomy is a good operation for treating patients with EC, which may offer an opportunity to treat cases who cannot have thoracotomy.

Abstract
Objective: To evaluate the safety and efficacy of stent-assisted coil embolization in patients with recurrent intracranial bifurcation aneurysms,after initial simple coiling or microsurgical clipping. Methods: Clinical data of 20 patients with recurrent intracranial bifurcation aneurysms who initially underwent simple coiling or surgical clipping and subsequently re-treated by stent-assisted coiling embolization at the Radiology Intervention Department of Huashan Hospital between March 2009 and November 2019 were collected and analyzed retrospectively.There were 9 males and 11 females,with a median age of 55.5 years (range:33 to 71 years),including 17 aneurysms initially treated with simple coiling and 3 treated with surgical clipping.All cases were re-treated with stent-assisted coiling,15 using a single stent and 5 employing two stents in a Y-configuration.Peri-and post-operative complications and outcomes were evaluated.Mann-Whitney U tests were performed to compare the follow-up duration between initial treatment and re-treatment.Student's t tests were used to compare the parent artery angles before re-treatment, after re-treatment and at the last follow-up. The parent artery angle was defined using the proximal main trunk and the stented branch. Results: Immediate complete occlusion (Raymond Ⅰ) was achieved in 18 aneurysms (90.0%) while 2 aneurysms (10.0%) had a residual neck (Raymond Ⅱ).The median follow-up time(M(QR)) was 8.5(16.3)months,which had no significantly different from the initial treatment follow-up duration (15.5(27.0)months)(U=157.7,P=0.25). During the follow-up period,2 aneurysms (10.0%) with immediate post-operative residual necks recanalized again,including 1 aneurysm re-treated with the Y-configuration stent.Symptomatic thromboembolic complications occurred in 6 patients,including 4 re-treated with the Y-configuration stent.No peri-operative hemorrhagic complications occurred,along with no operation-related permanent disability or death. The parent artery angle increased significantly from pre-operative(90.1±21.1)°to post-operative and the last follow-up ((115.4±28.9)° and (132.6±26.8)°);t=5.14,P<0.01;t=7.78,P<0.01). Conclusion: For recurrent intracranial bifurcation aneurysms after initial surgical clipping or simple coiling,stent assisted coil embolization is proved to be safe and can decrease recurrence rate.

Abstract
Objective: To explore the effects of environmental, genetic factors as well as the interactions in early life on the short-term and long-term health of offspring and to systematically evaluate the pregnancy outcomes and health of offspring after birth between families with assisted reproductive technology (ART) conception and families with spontaneous conception. Methods: The China National Birth Cohort (CNBC), a multicenter prospective birth cohort study, includes both families with ART conception and families with spontaneous conception. Since 2016, CNBC has recruited families from 24 hospitals located in 12 provinces, municipalities and autonomous regions throughout China. Information and biospecimens were collected before ART treatment, embryo transfer, at early, second, third trimester and delivery, and at 42 days, 6, 12 and 36 months after birth. Results: By June 2020, CNBC had included 27 044 families with ART conception and 29 589 families with spontaneous conception. The majority of the participants are urban residents. Among the families with ART conception, 65.5% of the men and 63.7% of the women had college degrees or higher. The mean age distribution of men and women was (33.83±5.52) and (32.38±4.67) years. 83.2% of women were primiparas, and the prevalence rates of current regular smokers and current alcohol drinkers were 0.8% and 2.1% in women. Among the families with spontaneous conception, 81.5% of the men and 86.5% of the women had college degrees or higher. The mean age distribution of men and women was (32.06±5.09) and (30.40±4.27) years. 67.2% of women were primiparas, and the prevalence rates of current regular smokers and current alcohol drinkers were 0.1% and 2.2% in women. The baseline characteristics were different between the families with ART conception and spontaneous conception in different regions. Conclusion: CNBC provides a powerful and rich resource in studying the impact of genetic, environmental factors and interactions in early life and ART treatment on the health of offspring after birth.

Abstract
The importance of gut microbes to human health has gradually attracted attention. With the use of animal models, it has been revealed that maternal microbes during pregnancy could influence their children's health outcomes through shaping their microbial composition and regulating the development of their metabolic and immune system. However, the physiological mechanism of the human body is more complex and is affected by the interaction of multiple factors. The research results obtained from animal models are often inconsistent with human studies. At present, the influence of maternal intestinal microbes during pregnancy on the microbial colonization in their offspring and on a series of children's health outcomes is still unclear. Establishing a sub-cohort to detect the microbiome of the women across pregnancy and of their offspring, and further to integrate with variety of environmental and behavioral exposures can better provide reliable support for the research on the mechanism of children's health and diseases. This paper briefly introduces the research objectives, content, progress, strength and limitations of the sub-cohort study.

Abstract
Autism spectrum disorder (ASD), a representative disease of children's neurodevelopmental disorders, brings huge pressure and financial burden to families and society. It is of great significance to explore its etiology and pathogenesis. Therefore, we established an ASD Cohort based on the existing China National Birth Cohort (CNBC), which applied parallel design to recruit and follow up families who achieved pregnancy after receiving assisted reproductive technologies (ART) and families with spontaneous conception. The main aims of this study are to compare the incidence of ASD among children born after ART with those born under spontaneous pregnancy, and to evaluate the impact of ART on the neurobehavioral development of offspring. Additionally, with a variety of clinical and behavioral related information collected during pregnancy and at early life of offspring, we are able to investigate the risk factors associated with ASD comprehensively. This article briefly introduces the objectives, contents, preliminary progress, strength and limitations, as well as further prospects of the ASD cohort study, mainly focusing on the overall design and current progress.

Abstract
Birth cohort is an effective method to explore the relationship between various prepregnant and pregnant exposures and the health of fetuses, infants and young children. It is a long construction period to build a birth cohort and the quality of research may be affected by many factors. This paper reviews the quality assurance and quality control measures in the process of China National Birth Cohort (CNBC), and summarizes the construction experience. We aim to provide experience for related cohort studies, which could improve the quality of cohort studies through removing the impact of related factors. CNBC adopted a series of measures to ensure the quality of research in the top-level design of quality assurance, including screening research center, developing member management system, formulating standard operating procedures and training staff by it. In terms of quality control, it includes real-time, timely and timing quality control for the process of data generation, full-cycle quality control for biological sample collection, processing, storage and comprehensive three-dimensional quality control for staff training, supervision and quantitative assessment.

Abstract
OBJECTIVE To compare the difference of health-related quality of life after oncologic esophagectomy between the patients using Jiang's gastroesophageal anastomosis and traditional end-to-end gastroesophageal anastomosis. METHODS A total of 419 patients (223 in Jiang's anastomosis group, and 196 in end-to-end anastomosis group) underwent minimal invasive esophagectomy with cervical anastomosis from October 2012 to August 2016. All patients received radical esophageal cancer resection and cervical anastomosis. EORTC-QLQ-C30 and QLQ-OES18 were used to assess the health-related quality of life at the 1st, 3rd, 6th, 12th, 24th month after esophagectomy. RESULTS There were 25 dimensions and items in EORTC-QLQ-C30 and QLQ-OES18. The postoperative quality of life decreased obviously at the 1st month and then recovered obviously at the 6th month after the surgery, and it ranged small at the 12th and 24th month. Compared with end-to-end anastomosis group, Jiang's anastomosis group had less reflux and less cough at the 1st month (P=0.023, P=0.010) and the 3rd month (P=0.004, P=0.013), then had better emotional function, less reflux and less cough at the 6th month (P=0.013, P=0.014, P=0.043), better emotional function, less nausea, and less reflux at the 12th month(P=0.004, P=0.023, P=0.021), as well as less reflux at the 24th month (P=0.020). There was no significant difference in other dimensions and items between the two groups during the follow-up period. CONCLUSION Jiang's anastomosis is safe and feasible, and could improve the postoperative quality of life of the patients with esophagectomy. It is worth to further application in clinical practice.

Abstract
BACKGROUND Pioneering effort has been made to facilitate the recognition of pathology in malignancies based on whole-slide images (WSIs) through deep learning approaches. It remains unclear whether we can accurately detect and locate basal cell carcinoma (BCC) using smartphone-captured images. OBJECTIVES To develop deep neural network frameworks for accurate BCC recognition and segmentation based on smartphone-captured microscopic ocular images (MOIs). METHODS We collected a total of 8046 MOIs, 6610 of which had binary classification labels and the other 1436 had pixelwise annotations. Meanwhile, 128 WSIs were collected for comparison. Two deep learning frameworks were created. The 'cascade' framework had a classification model for identifying hard cases (images with low prediction confidence) and a segmentation model for further in-depth analysis of the hard cases. The 'segmentation' framework directly segmented and classified all images. Sensitivity, specificity and area under the curve (AUC) were used to evaluate the overall performance of BCC recognition. RESULTS The MOI- and WSI-based models achieved comparable AUCs around 0·95. The 'cascade' framework achieved 0·93 sensitivity and 0·91 specificity. The 'segmentation' framework was more accurate but required more computational resources, achieving 0·97 sensitivity, 0·94 specificity and 0·987 AUC. The runtime of the 'segmentation' framework was 15·3 ± 3·9 s per image, whereas the 'cascade' framework took 4·1 ± 1·4 s. Additionally, the 'segmentation' framework achieved 0·863 mean intersection over union. CONCLUSIONS Based on the accessible MOIs via smartphone photography, we developed two deep learning frameworks for recognizing BCC pathology with high sensitivity and specificity. This work opens a new avenue for automatic BCC diagnosis in different clinical scenarios. What's already known about this topic? The diagnosis of basal cell carcinoma (BCC) is labour intensive due to the large number of images to be examined, especially when consecutive slide reading is needed in Mohs surgery. Deep learning approaches have demonstrated promising results on pathological image-related diagnostic tasks. Previous studies have focused on whole-slide images (WSIs) and leveraged classification on image patches for detecting and localizing breast cancer metastases. What does this study add? Instead of WSIs, microscopic ocular images (MOIs) photographed from microscope eyepieces using smartphone cameras were used to develop neural network models for recognizing BCC automatically. The MOI- and WSI-based models achieved comparable areas under the curve around 0·95. Two deep learning frameworks for recognizing BCC pathology were developed with high sensitivity and specificity. Recognizing BCC through a smartphone could be considered a future clinical choice.

Abstract
BACKGROUND Anastomotic leakage, fibrous stricture and gastro-oesophageal reflux are three major complications of gastro-oesophageal anastomosis, particularly in cervical anastomosis. Our aim was to evaluate the safety and efficacy of a novel cervical anastomosis technique (NA) by comparing it to traditional side-to-side anastomosis (SS) and end-to-side anastomosis using a circular stapler (CS) in terms of postoperative leakage, stricture and reflux. METHODS A total of 390 patients with thoracic oesophageal cancer underwent minimally invasive oesophagectomy with cervical anastomosis (192 with NA, 34 with SS and 164 with CS) in our institute from January 2013 and May 2016. A detailed description of the surgical procedure is provided, and the major postoperative complications, including postoperative leakage, stricture and reflux, were compared using a three-armed controlled study. RESULTS The anastomotic method was an independent risk factor for anastomotic leakage, as well as stricture and reflux. The rate of anastomotic leakage of the NA group (1.0%) was significantly lower than that in the SS group (8.8%, P = 0.025) and in the CS group (8.5%, P = 0.001). The rate of anastomotic stricture in the NA group was not significantly different than that in the SS group (1.5% vs. 2.9%, P = 0.368) but was significantly lower than that in the CS group (1.5% vs. 18.9%, P < 0.001). The incidence of gastro-oesophageal reflux in the NA group was significantly lower than that in the SS group and the CS group (5.7% vs. 23.5% and 18.3%, P = 0.003 and 0.001, respectively). CONCLUSION Jiang's anastomosis technique remarkably reduces the incidence of gastro-oesophageal anastomotic leakage, stricture and reflux, and it is a safe and effective technique for minimally invasive oesophagectomy.

Abstract
Objective: To explore the method of extracting chaperone antigen peptide complexes from gastric cancer stem cells and its immune function. Methods: Gastric cancer stem cells and gastric cancer cells were screened by low temperature ultrasonic lysis. After salting out and dialysis, the lysate supernatant was processed with SDS-PAGE to analyze the expression of chaperone antigen peptide complexes, and then was separated and purified with CNBr-activated SepharoseTM 4B. Reverse high pressure liquid chromatography (HPLC), SDS-PAGE and Western blotting were used to analyze the purity and nature of the acquired albumen. Lymphocyte proliferation assay and lymphocytotoxicity assay were used to ditermine the immunological activity of the chaperone-antigen peptide complexes. Results: The chaperone antigen peptide complexes of gastric cancer stem cells were prepared and identified successfully, of which the main components were the antigen peptides of HSP60, HSP70, HSP90 and HSP110. 0.75 μg and 1.00 μg HSP70-antigen peptide and 1.00 μg HSP90-antigen peptide activated lymphocytes significantly. Their A(490) values were 0.26±0.03, 0.45±0.05 and 0.32±0.04, respectively, while the corresponding doses of HSP60-antigen peptide and HSP110-antigen peptide did not activate lymphocytes. The killing rates of 1.00 μg HSP70-antigen peptide and 1.00 μg HSP70 were (45.0±2.0)% and (16.0±2.0)%, respectively, showing a significant difference (P=0.012). Similarly, the killing rates of 1.00 μg HSP90-antigen peptide and 1.00 μg HSP90 were (36.0±5.0)% and (13.0±4.0)%, respectively, also showing a significant difference (P=0.048). Conclusions: The amount of chaperone antigen peptide complexes in gastric cancer cells is extremely low, but it is obviously increased in gastric cancer stem cells. After purification, the chaperone antigen peptide complexes with high purity can be prepared. The extracted chaperone antigen peptide complexes have stronger immunogenicity, and can be used to make tumor vaccine in vitro, which may have a good application value in the targeted therapy of gastric cancer.

Abstract
OBJECTIVE To investigate the clinical significance of the three-step approach in laparoscopic hemihepatectomy. METHODS A total of 32 patients received laparoscopic hemihepatectomy with the three-step approach in Yijishan Hospital affiliated to Wannan Medical College between Aug 2013 and Oct 2015. All patients underwent thin slice CT scan and hemihepatectomy was imitated with the imagic explorer, preoperatively. The vessel distribution was observed at the section and the three-step approach was used in the hemihepatectomy. Pre- and post-operative data were collected and analyzed retrospectively. RESULTS The length of middle hepatic vein (MHV) was (59.1±12.9) mm and the number of branchs to the left and right lobe were 3.07±0.78 and 3.11±0.64 respectively. The distance between the first branch of MHV and the diaphragmatic surface was (28.07±3.74) mm and the distance between MHV and the visceral surface was (14.4±4.3) mm. The laparoscopic surgeries (left hemihepatectomy in 28 and right hemihepatectomy in 4) were performed successfully in all cases with the three-step approach, without any conversion to the open surgeries. The operation time was (165±42) min in left hemihepatectomy and (305±50) min in right hemihepatectomy. The intraoperative blood loss was (242±65) ml in left hemihepatectomy and (695±122)ml in right hemihepatectomy. All the patients recovered well without severe complications except for bile leakage in 3 patients who were cured with drainage. The postoperative hospital stay was (7.96±1.8) d. CONCLUSIONS the distribution of vessel is regional at the section of hemihepatectomy and the three-step approach based on this feature is safe and effective in laparoscopic hemihepatectomy, which can shorten the operation time and reduce the difficulty of operation.

Abstract
OBJECTIVE The killing effect of TNF mediated by conditionally replicating adenovirus SG502 on human cancer cell lines was assessed by in vivo and in vitro experiments. METHODS The recombinant adenovirus SG502-TNF was used to infect human lung cancer cell line A549 and human esophageal cancer cell line TE-1. The expression of the exogenous gene and its inhibitory effect on the tumor cell lines were thus detected. Tumor transplantation experiment was performed in mice with the purpose of assessing the inhibitory effect of the adenovirus on tumor cells and tumor formation. The targeting of the adenovirus and the mechanism of tumor inhibition were discussed by in vivo imaging technology, HE staining and TUNEL assay. RESULTS Recombinant adenovirus SG502-TNF targeted the tumor cells specifically with stable expression of TNF, which produced a killing effect on tumor cells by regulating the apoptotic signaling pathway. CONCLUSION Recombinant adenovirus SG502-TNF possessed significant killing effect on TE-1 cells either in vivo or in vitro. This finding demonstrated the potential clinical application of adenovirus SG502.

Abstract
We performed a 1-year cluster-randomized field trial to assess the effect of standardized management of chronic obstructive pulmonary disease (COPD) on lung function and quality of life (QOL) measures in patients in China. We used the Global Initiative for Chronic Obstructive Lung Disease (GOLD) treatment guidelines and assessed indexes including pulmonary function, QOL, quality-adjusted life years (QALY), Medical Research Council (MRC) dyspnea scale, 6-min walk distance (6-MWD), number of emergency visits, and frequency of hospitalization. Of a total of 711 patients with chronic cough and asthma, 132 were diagnosed as having COPD and 102 participated in this study [intervention group (N = 47); control group (N = 55)]. We found that adherence to GOLD guidelines had a perceivable impact on 6-MWD, MRC dyspnea scale score, and QOL. The average QALY increased by 1.42/person/year in the intervention group, but declined by 0.95/person/year in the control group. We conclude that standardized management improves disease severity, QOL, and QALY in COPD patients when treatment protocols adhere to GOLD guidelines.

Abstract
Hemangioblastoma of the central nervous system occurs as sporadic tumors or as a part of von Hippel-Lindau (VHL) disease, an autosomal dominant hereditary tumor syndrome caused by a germline mutation in the VHL tumor suppressor gene. We screened a Chinese family with VHL for mutations in the VHL gene and evaluated a genetic test for diagnosing VHL disease and clinical screening of family members. DNA extracted from the peripheral blood of all live members and from tissue of deceased family members with VHL disease was amplified by polymerase chain reaction to 3 VHL gene exons. Mutations in the amplification products were compared against the Human Gene Mutation Database. The involvement of multiple organs among the kindred with VHL disease was confirmed by medical history and radiography. Of the 12 members of the 4-generation family, 5 were diagnosed with VHL disease. Patient age at the initial diagnosis was 26-36 years (mean = 31 years). The mean time was 15 (11-19 months) from symptom appearance to the first patient visit to the hospital. Sequence analysis revealed that the frameshift mutation 327del C (p.Gly39Alafs*26) in exon 1 affected all family members, but not the healthy individuals or 16 unrelated controls. Members without gene mutation showed no clinical manifestation of VHL disease. We detected a conserved novel frameshift mutation in the VHL gene of the family members that contributes to VHL. DNA analysis of VHL is advantageous for VHL diagnosis. We developed a quick and reliable method for VHL diagnosis.

Abstract
A study was conducted to evaluate effects of alfalfa meal on growth performance and gastrointestinal tract development of growing layer ducks to provide evidence for application of alfalfa meal in the duck industry. Two hundred and fifty-six healthy Shaoxing 7-wk old growing layer ducks were selected and randomly allocated to 1 of 4 dietary treatments based on corn and soybean meal and containing 0, 3, 6, and 9% of alfalfa meal for 8 wks. Each treatment consisted of 4 replicates of 16 ducks each. Briefly, birds were raised in separate compartments, and each compartment consisted of three parts: indoor floor house, adjacent open area and a connecting water area. The results showed: i) Growing ducks fed alfalfa meal diet were not significantly different in average daily gain, feed intake and gain-to-feed ratio from those fed no alfalfa diet (p>0.05). ii) Alfalfa meal increased the ratio crop, gizzard to live weight, caecum to live weight, the caecum index of growing ducks (p<0.05). iii) Villus height in duodenum and jejunum of growing ducks increased significantly with the increase of alfalfa meal levels (p<0.05). Crypt depth in duodenum and jejunum of growing ducks decreased significantly with the increase of alfalfa meal levels (p<0.05). This experiment showed that feeding of alfalfa meal to growing layer ducks could improve gastrointestinal tract growth and small intestinal morphology without effect on performance. This experiment provides evidence that alfalfa meal is a very valuable feedstuff for growing layer ducks.

Abstract
This study was conducted to investigate the effects of alfalfa meal diets on the intestinal microbial diversity and immunity of growing egg-type ducks. A total of 128 healthy 7-week-old female egg-type Shaoxing ducks were selected and randomly assigned into four dietary treatments: 0%, 3%, 6% and 9% alfalfa meal for 8 weeks. Each treatment consisted of four replicates of eight ducks each. Polymerase chain reaction denaturing gradient gel electrophoresis (PCR-DGGE) was used to characterize the microbiota. The results showed that the DGGE fingerprints of the V6-V8 fragments of the 16S rRNA from the caeca and faeces of ducks fed 3%, 6% and 9% alfalfa meal had significantly higher microbiota species richness than those fed 0% alfalfa meal (p < 0.05). The Shannon-Weiner index of the microbiota from the caeca and faeces of ducks fed 3%, 6% and 9% alfalfa meal was significantly higher than those fed 0% alfalfa meal (p < 0.05). Molecular analysis of the caecal and faecal DNA extracts showed that the alfalfa meal diet promotes the intestinal microbial diversity, as indicated by their higher species richness and Shannon-Weiner index. However, the groups did not significantly differ in terms of average daily gain, feed intake and gain-to-feed ratio (p > 0.05), and the 3-9% alfalfa meal did not affect the growth performance of the growing egg-type ducks. The proliferation of T and B lymphocytes was significantly greater (p < 0.05) in the groups supplemented with 3%, 6% and 9% of alfalfa meal than the unsupplemented control group, and alfalfa meal promoted the lymphocytes proliferation of the growing egg-type ducks. Dietary alfalfa meal supplementation increases intestinal microbial community diversity and improves of the immune response growing egg-type ducks.

Abstract
Prolactin (PRL) plays central roles in mammals' reproduction, gland development, milk secretion, and the expression of milk protein genes. In dairy cattle, the PRL gene is a potential quantitative trait locus and genetic marker related to milk performance traits. Here, a total of 586 randomly selected Chinese Holstein cows were genotyped for locus PRL-RsaI. One haplotype block containing eight SNPs was identified in the region from intron 3 to intron 4 of the PRL gene in Chinese Holstein cows. One tag SNP (7545 G → A) was selected to represent the haplotype block defined by the genotypic data. The cows with genotype AA of this tag SNP had a higher milk yield at 305 days (8457 ± 938 kg) than the cows with GA (7537 ± 1278 kg; P < 0.01) or GG (7757 ± 1174 kg; P < 0.05). This suggests that the haplotype block examined in this study contains important markers for milk production traits in Chinese Holstein cows.

Abstract
The signal transducer and activator of transcription (STAT) genes are responsive to a wide range of cytokines, growth factors, and hormones, and thus control important biological processes. In humans, STAT4 mutations have been identified as genetic markers for rheumatoid arthritis, systemic lupus erythematosus, and primary Sjögren's syndrome, whereas little research has been conducted on bovine STAT4 mutations and their potential effects. Herein, 585 Chinese Holstein cows were used to investigate STAT4 mutations and their effects on milk performance traits. One haplotype block, containing g.95879G>A, g.96013G>C, was identified in intron 20 of the bovine STAT4 gene by restriction fragment length polymorphism-polymerase chain reaction and DNA sequencing. Two single nucleotide polymorphisms were significantly associated with milk yield at 305 days (P < 0.05), and with protein percentage (P < 0.05). Chinese Holstein cows with the haplotype GGGG had higher milk yields at 305 days and lower protein percentages. These results suggest that the 2 single nucleotide polymorphisms of STAT4 could be used as genetic markers for milk performance traits in Chinese Holstein cows.

Abstract
The melanocortin-4 receptor (MC4R) has important roles in regulating food intake, energy balance, and body weight in mammals. In pigs and cattle, MC4R mutations have been identified as genetic markers for growth and traits. Compared with abundant research conducted on other livestock species, little is known about mutations of the ovine MC4R gene. We investigated the effect of MC4R polymorphisms on birth weight and on 45-day weaning weight in 144 Hu sheep. Four single nucleotide polymorphisms (SNPs; g.1016 G/A, g.1240 T/C, g.1264 G/A, and g.1325 A/G) were identified in the 3ꞌ-untranslated region of Hu sheep MC4R by PCR-single-strand conformation polymorphism and DNA sequencing. A haplotype block, containing g.1240 T/C, g.1264 G/A, and g.1325 A/G, was constructed within the Hu sheep MC4R gene. Four SNPs were found to be significantly associated with 45-day weaning weight, while the haplotype block was significantly associated with birth weight. Hu sheep with the genotypes GG in g.1016 G/A or with the genotype CCAAGG in the haplotype block, had higher 45-day weaning weights. We conclude that these 4 SNPs of the MC4R gene have potential as genetic markers for early growth traits in Hu sheep.

Abstract
This report describes a 59-year old woman with a rare choroid plexus papilloma of the cerebellopontine angle presenting with trigeminal neuralgia. The patient was admitted complaining of a 12-year history of paroxysmal lancinating pain throughout the right side of her face. Treatment with carbamazepine, Chinese medicine and a peripheral neurectomy had not relieved the pain. At operation, a 0.5 x 0.5 x 0.5 cm neoplasm was found in the cerebellopontine angle, which was firmly adherent to the roots of the seventh and eighth cranial nerves and the brainstem. There was no apparent tumour bulk or vascular compression around the trigeminal nerve root entry zone. Subtotal tumour excision and selective partial rhizotomy were performed. The patient's facial pain gradually resolved. Involvement of the trigeminal nucleus in the brainstem by the cerebellopontine angle tumour is suggested as the possible cause for trigeminal neuralgia in this case.

Abstract
AIM To study the effect of sodium nitroprusside (SNP) on the hemodynamics of corpus cavernosum in Chinese men with erectile dysfunction (ED). METHODS In 68 ED patients receiving intracavernous injection (ICI) of SNP, the cavernous hemodynamics were studied by Doppler ultrasonography. RESULTS The peak flow velocity (PFV), the artery diameter (Ad), the mean velocity of arterial blood (MV) and the vein diameter (Vd) were significantly higher after ICI of SNP than before ICI, but the end diastolic velocity (EDV) did not change significantly. CONCLUSION The increase in Vd after SNP suggests that the venous outflow is not invariably decreased during penile erection.

Abstract
In this paper, the excited state dynamics properties of hemicynine were investigated by using time-resolved fluorescence and 3D fluorescence spectra techniques. The interaction of hemicyanine molecules caused formation of H-aggregates and a blue shift of the 3D fluorescence spectra in interleaving hemicyanine/arachidic acid multilayers. The peak of fluorescence was a red shift along with the time decay. The lifetime of the LB fluorescence was much shorter and the difference of beginning luminescence was less than that of the hemicyanine solution due to the stronger intermolecule interactions in the aggregates.

Abstract
OBJECTIVE To explore the feasibility of intraoperative application of mitomycin C (MMC) in pterygium and observe the ultrastructure change of pterygium with or without intraoperative application of MMC. METHODS Sixty two eyes of 57 patients with primary pterygium were randomly divided into MMC group and control group, 29 patients (32 eyes) in MMC group underwent transposition with intraoperative application of MMC (0.4 mg.ml-1 for 1 minute), whereas 28 patients (30 eyes) in control group underwent transposition. The recurrence rate, complications and side effects were observed and compared between the two groups. The ultrastructure of pterygium with or without intraoperative application of MMC was studied with transmission electron microscopy. The mean follow-up was(7.6 +/- 3.4) months (1-13 minths). RESULT Eleven eyes of the 30 eyes in control group (36.%) showed recurrence, whereas only 2 of 32 eyes (6.3%) in MMC group showed recurrence (P < 0.005). No severe complication and side effect appeared during the follow-up. Most of fibroblasts in pterygium that underwent intraoperative MMC occurred the change of rough endoplasmic reticulum (RER) dilatation. CONCLUSION Intraoperative MMC appears to be an effective treatment in preventing recurrence of primary pterygium. The fibroblasts in pterygium have RER dilatation after application of MMC for 1 minute during the operation.

Abstract
AIM To study the effect of intracavernous sodium nitroprusside (SNP), a nitric oxide (NO) donor, on penile erection. METHODS Forty-two patients with erectile dysfunction (ED) were randomly assigned to receive SNP 300 micrograms or the control drugs (papaverine 30 mg + phentolamine 1 mg) intracavernously crosswise one week apart. The penile length, circumference and hardness after the administration of the experimental and control drugs were assessed and compared statistically. RESULTS (1) There was no significant difference between the changes in penile length and circumference in the two occasions; (2) In 25 SNP and 28 control cases, the hardness of the penis was scored above 100 as evaluated by the Virag method (P > 0.05); (3) The duration of erection in the controls was longer than that in the SNP, but there were three priapism in the controls and not a single one in the SNP; (4) there was no apparent change in the heart rate and blood pressure in both occasions; other side effects were minimal except slight local pain in a few controls. CONCLUSION SNP facilitates relaxation of the penile smooth muscle and penile erection without significant side effects. SNP may be used in ED patients that experience pain and priapism with papaverine/phentolamine.

Abstract
The anticancer drug paclitaxel (Taxol) has been converted to a large number of 2-debenzoyl-2-aroyl derivatives by three different methods. The bioactivities of the resulting analogues were determined in both tubulin polymerization and cytotoxicity assays, and several analogues with enhanced activity as compared with paclitaxel were discovered. Correlation of cytotoxicity in three cell lines with tubulin polymerization activity showed reasonable agreement. Among the cell lines examined, the closest correlation with antitubulin activity was observed with a human ovarian carcinoma cell line.

Abstract
A room temperature biochemical assay, based on centrifugal removal of tubulin polymer, was developed to permit ready detection of paclitaxel analogs more active than the parent compound and to permit reliable quantification of differences in activity relative to paclitaxel in terms of drug concentration. The assay was validated by comparing paclitaxel to two compounds (docetaxel and 2-debenzoyl-2-meta-azidobenzoylpaclitaxel) known to be more active under multiple reaction conditions. The assay was designed to yield a relatively high EC50 (23 microM) for paclitaxel. This was possible because paclitaxel only weakly induced tubulin assembly at room temperature in 0.4 M glutamate without exogenous GTP. Under these same reaction conditions 50% assembly occurred with 4.7 microM 2-debenzoyl-2-meta-azidobenzoylpaclitaxel and 11 microM docetaxel. These biochemical EC50 values were in agreement with the relative cytotoxicity of the three compounds for human Burkitt lymphoma CA46 cells (IC50 values for paclitaxel, docetaxel, and 2-debenzoyl-2-meta-azidobenzoylpaclitaxel were 40, 10, and 3 nM, respectively).

Abstract
Vascular smooth muscle cell (SMC) proliferation in response to injury is an important etiologic factor in vascular proliferative disorders such as atherosclerosis and restenosis after balloon angioplasty. The retinoblastoma gene product (Rb) is present in the unphosphorylated and active form in quiescent primary arterial SMCs, but is rapidly inactivated by phosphorylation in response to growth factor stimulation in vitro. A replication-defective adenovirus encoding a nonphosphorylatable, constitutively active form of Rb was constructed. Infection of cultured primary rat aortic SMCs with this virus inhibited growth factor-stimulated cell proliferation in vitro. Localized arterial infection with the virus at the time of balloon angioplasty significantly reduced SMC proliferation and neointima formation in both the rat carotid and porcine femoral artery models of restenosis. These results demonstrate the role of Rb in regulating vascular SMC proliferation and suggest a gene therapy approach for vascular proliferative disorders associated with arterial injury.

Abstract
A new method of measuring the iris contour has been set up with a personal computer. The model of a parabolic curve, an approximate mimic iris contour curve, was traced to define the profile contour of the iris from a photograph. A radius measured from the apex of the curvature of the parabola, named iris radius (IR), was calculated by a computer to describe the degree of the curvature of the iris contour. The iris radius of 93 eyes of 68 cases with early pupillary block primary angle closure glaucoma were measured by this method. The results show that the mean iris radius of cases with glaucoma is shorter than that of the normal age matched controls (53 cases 106 eyes) and there is statistical significant difference (P < 0.01). This method of measurement can be an effective method to further study the early diagnosis and pathogenic mechanism of the pupillary block angle closure glaucoma.
