Abstract
Objective: To evaluate the hemostatic efficacy, safety and immunogenicity of recombinant human thrombin in the treatment of liver wounds that still ooze after conventional surgical hemostasis. Methods: A multicenter, stratified randomized, double-blind, placebo-controlled phase Ⅲ trial with a planned enrollment of 510 subjects at 33 centers, with a 2∶1 randomization to the thrombin group versus the placebo group. An interim analysis will be conducted after approximately 70% of the subjects have completed the observation period. The primary efficacy endpoint was the rate of hemostasis within 6 minutes at the point of bleeding that could be evaluated. Safety analysis was performed one month after surgery, and the positive rates of anti-drug antibody (ADA) and neutralizing antibody were evaluated. Results: At the interim analysis, a total of 348 subjects had been randomized and received the study drug (215 were male and 133 were female). They were aged 19-69 (52.9±10.9)years. Among them, 232 were in the thrombin group and 116 were in the placebo group, with balanced and comparable demographics and baseline characteristics between the two groups. The hemostasis rate at 6 minutes was 71.6% (95%CI:65.75%-77.36%) in the thrombin group and 44.0% (95%CI: 34.93%-53.00%) in the placebo group, respectively (P<0.001). No grade≥3 drug-related adverse events and no drug-related deaths were reported from the study.No recombinant human thrombin-induced immunologically-enhanced ADA or immunologically-induced ADA was detected after topical use in subjects. Conclusion: Recombinant human thrombin has shown significant hemostatic efficacy and good safety in controlling bleeding during liver resection surgery, while also demonstrating low immunogenicity characteristics.

Abstract
Objective: To investigate the differences in molecular classification of endometrial carcinoma (EC) between various technical methods and to explore molecular classification schemes suitable for Chinese population. Methods: The study used a comprehensive scheme of next generation sequencing (NGS) and immunohistochemistry for molecular classification of 254 EC cases that were obtained at Department of Pathology, Obstetrics and Gynecology Hospital of Fudan University, Shanghai, China from April 2021 to March 2022. According to the recommended threshold of Sanger sequencing which was approximate-20% variant allele fraction (VAF), NGS data were extracted to simulate the results of Sanger sequencing. Results: The 254 EC patients had a mean age of 51 years (range, 24 to 89 years). Combination of POLE (9-14 exons), TP53 total exons and microsatellite instability (MSI) detection was a better single scheme than NGS alone, while combination of MSI fragment analysis and conventional immunohistochemistry was the best solution and seemed best aligned with TCGA data and recent studies. POLE ultramuted type, mismatch repair defect type, TP53 mutant type and non-specific molecular characteristic type accounted for 11.4% (29/254), 31.5% (80/254), 22.4% (57/254) and 34.6% (88/254) of the cases, respectively. If Sanger sequencing was adopted for POLE and TP53 detection, the frequencies of these EC types were 9.1% (23/254), 31.5% (80/254), 12.9% (33/254) and 46.6% (118/254), respectively, with greatly increasing non-specific molecular characteristics cases. If POLE was detected by Sanger sequencing and others by immunohistochemistry, they were 9.1% (23/254), 42.2% (92/218), 13.8% (35/254) and 40.9% (105/254), respectively, with increasing the false positive rates of the mismatch repair defect group. Conclusions: Small and medium-sized NGS panels with MSI detection is a better solution than NGS alone. Sanger sequencing is currently available for POLE mutation detection, which is not sensitive enough for TP53 mutation detection, and seems equivalent to the efficiency of TP53 by immunohistochemistry. Further optimization of small and medium-sized NGS panels covering MSI detection and POLE and TP53 full exons may be the best choice for the future to meet national conditions.

Abstract
The multi-scale variation trend of PM2.5-O3 compound pollution events was analyzed based on air quality data, meteorological data, and COVID-19 data in Beijing from 2015 to 2020. For the threshold of compound pollution, a compound pollution index was proposed, and the numerical response trend was evaluated based on the generalized additive model. A distributed lag nonlinear model was introduced to analyze the risk response relationship between compound pollution and influencing factors. The results showed that the events of PM2.5-O3 compound pollution in Beijing decreased annually. At the same time, due to the influence of pollutant emissions and meteorological conditions, there were obvious seasonal effects, week effects, holiday effects, and epidemic effects. The composite pollution index had no correlation with rainfall but had a linear positive correlation with O3 and air temperature and a nonlinear correlation with other explanatory variables. Air pollutants and meteorological conditions had obvious lag effects on the composite pollution index, and the lag effects were mainly concentrated in 1-3 d. PM2.5, PM10, O3, SO2, and air temperature in high-value areas significantly increased the risk of compound pollution. The CO (1-6 mg·m-3), NO2 (38-118 μg·m-3), and relative humidity (54%-87%) in the median section would also increase the risk of compound pollution, as would low wind speed. The compound pollution events showed a trend of multi-day continuous pollution in the numerical response. Compared with PM2.5 and PM10, compound pollution events were more dependent on O3, and the compound pollution rate in high-value areas was 30.7%-47.5%. CO and relative humidity had little effect on compound pollution events. The air temperature had the greatest impact, and 84.7% of the composite pollution incidents occurred at 20-30℃.

Abstract
Hepatocellular carcinoma (HCC) owns the high morbidity and mortality rates. Surgical resection is still the major pathway for the longer survival of HCC patients. Postoperative recurrence and metastasis have become the key impairment of prognosis of HCC patients. The relationship between tumor recurrence and surgical manner underwent by HCC patients is complicated and multiple factors are included. When the liver tumor was pressured during operation, tumor cells could be squeezed into blood flow via the broken vessels, which resulted in tumor metastasis. Besides, ischemia-reperfusion injury induced by Pringle maneuver during the liver blood blockade resulted in the immune destruction of liver and induced tumor recurrence.The destruction of physical barriers consisted of interstitial cells and normal liver cells was also a key factor for tumor recurrence. This paper summarizes the possible relationship between postoperative recurrence and surgical manner in HCC patients to provide the preventive suggestions for the postoperative recurrence of HCC patients.

Abstract
Objective: To investigate the molecular mechanism of nest metastasis in blood vessels encapsulated by tumor clusters (VETC) positive hepatocellular carcinoma (HCC). Methods: A total of 72 paraffin embedded HCC tissue samples were collected. Immunohistochemistry staining with CD34 (vascular endothelial cell marker protein) was used to observe the morphological manifestations of VETC cancer nests in primary tumors, bile duct cancerous thrombi and portal vein cancerous thrombi, and to study the characteristics of hematogenous metastasis of VETC cancer nests. Bioinformatics was used to predict the key proteins closely related to VETC cancer nest formation. Immunohistochemistry was used to detect the expression of angiogenin-2 (Ang-2), integrin α5, Integrin β1, and cyclooxygenase-2 (COX-2) proteins in HCC. Transwell cell migration assay was used to detect the effect of Ang-2/integrin α5β1 protein on the migration ability of endothelial cells and HCC cells. Western blotting was used to detect the effect of Ang-2/integrin α5β1 protein on the activity of focal adhesion kinase (FAK) protein. Results: Of the collected HCC specimens, 27 cases (27/72) were VETC (+), including 3 cases with biliary duct cancerous thrombus, 5 cases with portal vein cancerous thrombus, and 3 cases with both biliary duct cancerous thrombus and portal vein cancerous thrombus. VETC (+) HCC could metastasize to portal vein, bile duct, and liver in the form of cancer nest, and the nests retain their intact structure. Ang-2, integrin α5 and integrin β1 were overexpressed in tumor cells and endothelial cells of VETC (+) HCC nests, while COX-2 was only overexpressed in tumor cells of VETC (+) HCC nest. Ang-2 could promote the migration of HCC cell [(121±12) vs (186±11), P<0.01] and endothelial cells [(81±7) vs (163±14), P<0.01]. Integrin α5β1 activation antagonist ATN-161 could significantly block the ability of Ang-2 to promote the migration of HCC cells [(185±10) vs (135±9), P<0.05] and endothelial cells [(156±14) vs (103±6), P<0.05]. ATN-161 could significantly block the phosphorylation of FAK in HCC and endothelial cells induced by Ang-2. Conclusions: VETC (+) HCC could metastasize as a whole in a nested form, and possesses a specific regulatory protein. Ang-2/α5β1/FAK might be potential protein targets in the treatment of VETC (+) HCC nest-type metastasis.

Abstract
An estimate of about 50% of new liver cancer cases worldwide occur in China every year.Surgical resection is still the major treatment choice for longer survival of patients with hepatocellular carcinoma. Blocking hepatic blood flow and reducing intraoperative bleeding ensure the success of the operation. Anatomic separation of hepatic hilar region is the precondition of hepatic inflow occlusion. The hepatic hilar plate system involves a thick layer of connective tissue covering the hepatic inflow ducts of hepatic hilar region. The descending part of hilar plate assists in reducing the anatomical difficulty of the hepatic hilar region. The "forth porta hepatis" that is hidden in the hepatic hilar plate system involves the accumulation area of "short hepatic portal veins" .The communicating branch vessels between the hepatic inflow vessels form the anatomical basis in reducing the indocyanine green fluorescence stain effect.The relatively fixed position of the hepatic portal plate is considered as a positioning marker for accurate liver resection. The intrahepatic Glisson sheath is connected with thick connective tissue of the hepatic portal panel system, and is regarded as the physical barrier in limiting the proliferation and hypertrophy of hepatocytes and continuation of hepatic portal panel system in the liver.This paper summarizes the anatomy and application of hepatic hilar plate system during hepatobiliary surgery.

Abstract
BACKGROUND This study aimed to analyze the dynamic changes of the scientific research innovation efficiency of Guangzhou Institute of Respiratory Diseases (GIRD) during the year 2009-2013 to explore the reason for these changes and give some suggestions on how to improve the overall efficiency of the Institute. METHODS The panel data used in this study were taken from 19 research teams of GIRD during 2009 to 2013. Data envelopment analysis (DEA) based on Malmquist index (MI) was used to analyze the performance of each research team in terms of productivity changes over time. Data were analyzed using DEAP 2.1 software. RESULTS The annual average increase rate of total factor productivity (TFP), technological progress, technical efficiency, pure technical efficiency, and scale efficiency was 30.4%, 22.5%, 6.4%, 0.9%, and 5.4%, respectively from 2009 to 2013. The scientific research innovation efficiency of the GIRD was generally high and kept on growing. The increase of TFP was mainly caused by the progress of tech, the descending of TFP in some teams should be mainly attributable to the declining pure technical efficiency, and scale efficiency on the whole, maintaining a stable growth at a low speed. CONCLUSIONS To achieve higher scientific research innovation, GIRD not only needs to further improve the management level and introduce advanced management mode, but also needs to focus on optimization of resource allocation, as well as to strengthen the talent introduction, and continue to maintain the absorption of new technologies and innovation.

The study isolated three strains of intestinal autochthonous bacteria Aeromonas veronii BA-1, Vibrio lentus BA-2, and Flavobacterium sasangense BA-3 from the intestinal tract of the common carp (Cyprinus carpio). To reveal the effects of these three strains of bacteria on the innate immunity of carp, the lysozyme, complement C3, total serum protein, albumin and globulin levels, respiratory burst activity, phagocytic activity by blood leucocytes and the expression of IL-1b, lysozyme-C, and TNF-α were examined after feeding with seven different diets for up to 28 days. Also the survival of carp against Aeromonas hydrophila was challenged for 14 days. The carp were fed seven different diets: one control, three diets supplemented with 1 × 10(8) cell g(-1) of carp intestinal bacteria BA-1 (Group D-I), BA-2 (Group D-II) and BA-3 (Group D-III), and three diets supplemented with extracellular products FA-1 (Group E-I), FA-2 (Group E-II) and FA-3 (Group E-III) which were corresponding to the strains BA-1, BA-2, and BA-3, respectively, up to 28 days. For groups D-I, D-III, E-I and E-III, the innate immune parameters of carp were significantly increased, the expression of three immune-related genes in blood was significantly up-regulated examined during 7, 14, and 21 days of feeding, and the survival rate was improved. The study indicates that the two isolated intestinal autochthonous bacteria A. veronii BA-1 and F. sasangense BA-3 could positively influence immune response and enhance disease resistance of carp against A. hydrophila infection.

Abstract
BACKGROUND Mental health literacy (MHL) is the term used to describe people's knowledge and beliefs about mental disorders which aid in the recognition, management or the prevention of illness. Health professionals' levels of MHL will shape the therapeutic relationship in which they work in partnership with patients. Studies have been conducted in Australia and Singapore to determine levels of MHL among members of the general public and health professionals. To date, no such studies have been published in Chinese populations. AIM The study aims to compare levels of MHL between registered nurses and psychiatrists in a Chinese general hospital. The paper reports participants' diagnosis and beliefs about interventions used to manage depression and schizophrenia. METHODS A descriptive cross-sectional survey was undertaken among a group of psychiatrists and registered nurses in the psychiatric department of one large teaching hospital in China (n=70). Participants completed the survey by rating written vignettes related to depression and schizophrenia. RESULTS The psychiatrists were highly accurate in correctly diagnosing both depression and schizophrenia; the registered nurses were less so for diagnosing depression. In terms of treatment options, the two groups reached a broad agreement on beliefs about the use of mental health interventions, but differed significantly in the use of some specific mental health interventions. CONCLUSIONS This study provides preliminary information about levels of MHL among Chinese mental health professionals and describes their attitudes towards the helpfulness of interventions used to restore mental health and well-being. Future large-scale studies are required to identify factors that influence beliefs about the use of mental health interventions. The findings have implications for further education of registered nurses in the specialization of mental health nursing in China.

Abstract
Influenza A viruses of subtypes H1N1 and H3N2 have been reported widely in pigs, associated with clinical disease. These mainly include classical swine H1N1, avian-like H1N1, and human-like or avian-like H3N2 viruses. From 2005 to 2006, we carried out swine influenza virus surveillance in eight provinces of China. Here we report, for the first time, the isolation and genetic analysis of a human-like influenza H1N1 virus from a pig in a farm of Guangdong province of southern China, a host suspected to generate new pandemic strains through genetic reassortment. Each of the eight gene segments is of human origin. Phylogenetic analysis indicates that these genes form a human lineage, suggesting that this virus is the descendant of recent human H1N1 influenza viruses. In addition, four swine H3N2 viruses were also isolated. The three H3N2 viruses from Guangdong province are descendants of recent human viruses, while an H3N2 virus from Heilongjiang province derives from early human viruses. Isolation and genetic analysis of human H1N1 and H3N2 influenza viruses from pigs in China provides further evidence about the interspecies transmission of human influenza viruses to pigs and emphasizes the importance of reinforcing swine influenza virus surveillance.

Abstract
The morphological and biological properties as well as partial genomic sequencing of a granulovirus isolated from Clostera anachoreta (Lepidoptera: Notodontidae), C. anachoreta granulovirus (ClanGV), were carried out. The ovoidal occlusion bodies were 337 nm x 170 nm in size, and each granule contained one single rod-shape virion, with a mean size of 250 nm x 46 nm. Granulin had a molecular weight of approximately 30 kDa. ClanGV genome size was estimated as 104.34 kb based on the restriction fragments. The restriction pattern of the ClanGV genome was different from other GVs. A restriction fragment genomic library of ClanGV genome was constructed. The library consisted of nine SalI fragments, seven HindIII fragments and seven EcoRI fragments. One 4.8 kb fragment of the genome, digested by SalI, was sequenced and analyzed. This region was composed of eight unknown ORFs, two baculoviruses homologous gene (vp1054 and lef10) and partial sequence of lef-8. The unknown ORFs included three unique to ClanGV, the other five ORFs were related to baculoviruses. The ORFs, located within this restriction fragment, were compared to homologues in other GVs. The results indicated that ClanGV, CpGV, ClGV, AoGV and PoGV had similar arrangement and orientation of the homologous ORFs. Phylogenetic analysis of VP1054 proteins from 20 baculoviruses indicated that ClanGV was more closely related to CpGV, ClGV, AoGV and PoGV than to other baculoviruses.
