Objective:To construct a nomogram model for predicting the incidence of hepatocellular carcinoma based on serum abnormal prothrombin and alpha-fetoprotein and evaluate the predictive effect.Methods:Retrospective analysis of data from 351 patients with liver disease who received treatment at the First Affiliated Hospital of Zhengzhou University from January 2021 to December 2023, including 285 males and 66 females, aged (52.9±11.9) years. Among the 351 patients, there were 229 cases (65.2%) of hepatocellular carcinoma, 87 cases (24.8%) of liver cirrhosis, and 35 cases (10.0%) of chronic hepatitis B. All patients were randomly divided into a training set ( n=245) and a testing set ( n=106) in a 7∶3 ratio without replacement sampling. The training set was used to construct the model, and the testing set was used to evaluate the model. At the same time, gender, age, disease type, and other indicators were compared between the two sets. The risk factors of hepatocellular carcinoma were analyzed by univariate and multivariate logistic regression based on the training set, and a nomogram was constructed to predict the incidence of hepatocellular carcinoma based on the multivariate results. Receiver operating characteristic (ROC) curve and calibration curve were used to evaluate the predictive performance of nomogram, and decision curve analysis was used to evaluate the clinical applicability of the model. Results:There was no statistically significant difference in age, gender, disease type, etc. between the training and testing sets of patients (all P>0.05). Univariate logistic regression analysis showed that age, abnormal prothrombin logarithm (LnPIVKA-Ⅱ), alpha-fetoprotein logarithm (LnAFP), and diabetes were associated with hepatocellular carcinoma (all P<0.05). Multivariate logistic regression analysis showed that older age ( OR=1.07, 95% CI: 1.03-1.12), higher LnPIVKA-Ⅱ ( OR=2.97, 95% CI: 1.97-4.46), higher LnAFP ( OR=1.43, 95% CI: 1.11-1.84) and diabetes ( OR=5.17, 95% CI: 1.02-26.17) were risk factors for hepatocellular carcinoma (all P<0.05). Based on the above variables, a nomogram model for predicting the incidence of hepatocellular carcinoma was constructed. The area under the ROC curve analysis of the nomogram for predicting the incidence of hepatocellular carcinoma was 0.920 (95% CI: 0.886-0.953) in the training set and 0.934 (95% CI: 0.891-0.977) in the testing set. The calibration curve fit well with the standard curve, and the prediction was basically consistent with the actual situation. The decision curve analysis showed that the net benefit of the model was greater than 0 under most thresholds (0.1-1.0). Conclusion:The nomogram constructed based on age, LnPIVKA-Ⅱ, LnAFP and diabetes can effectively predict the incidence of hepatocellular carcinoma and has clinical applicability.

Hepatocellular carcinoma （HCC） with biliary duct tumor thrombus （BDTT） is currently not common in clinical practice and is easily misdiagnosed， and previously， it was often considered an advanced stage of the disease with a poor prognosis， making its treatment challenging. However， in-depth studies in recent years have gradually deepened our understanding of this disease， leading to significant changes in diagnostic and treatment concepts. Currently， comprehensive treatment， mainly surgery， is used for treatment， but there is still controversy over the selection of clinical treatment strategies. This article provides a detailed discussion on surgical methods and prognosis， in order to provide a reference for clinical treatment options.

Nipah virus (NiV) is a zoonotic paramyxovirus that has recently emerged as a crucial public health issue. It can elicit severe encephalitis and respiratory diseases in animals and humans, leading to fatal outcomes, exhibiting a wide range of host species tropism, and directly transmitting from animals to humans or through an intermediate host. Human-to-human transmission associated with recurrent NiV outbreaks is a potential global health threat. Currently, the lack of effective therapeutics or licensed vaccines for NiV necessitates the primary utilization of supportive care. In this review, we summarize current knowledge of the various aspects of the NiV, including therapeutics, vaccines, and its biological characteristics, epidemiology, pathogenesis, and clinical features. The objective is to provide valuable information from scientific and clinical research and facilitate the formulation of strategies for preventing and controlling the NiV.

Objective:To investigate and compare the clinical efficacy and prognosis of D3 lymphadenectomy/complete mesocolic excision in treatment of right colon cancer with different medial boundaries.Methods:We searched The Cochrane Library, Pubmed, Embase, CBM, VIP, CNKI, and WanFang data bases for superior mesenteric artery (SMA)-oriented and superior mesenteric vein (SMV)-oriented D3 lymphadenectomy/complete mesocolic excision from inception to December, 2023. The resultant data were submitted to meta-analysis using RevMan 5.3 software.Results:In total, we identified nine eligible studies involving 2467 patients. The SMA group had 982 patients and the SMV group had 1 485 patients. Meta-analysis revealed no significant differences in intraoperative bleeding volume, postoperative time to passage of flatus, or postoperative drainage volume between the two studied approaches. The durations of surgery and of postoperative hospital stay were both significantly longer in the SMA than SMV group (weighted mean difference [WMD]=17.70, 95%CI: 6.90–28.50, P=0.001; WMD=0.40, 95%CI: 0.07–0.72, P=0.020, respectively). Furthermore, the rate of postoperative complications was greater in the SMA than SMV group. For example, the incidences of postoperative chyle leakage and diarrhea were significantly higher in the SMA than SMV group, (OR=1.25, 95%CI: 1.01–1.54, P = 0.040; OR=3.60, 95%CI: 2.39–5.41, P < 0.001; OR=2.13, 95%CI: 1.10–4.11, P = 0.020, respectively). In terms of oncological efficacy, the total number of lymph nodes dissected and the number of positive lymph nodes in the SMA group were significantly higher than in the SMV group (WMD=2.76, 95%CI:1.22–4.31, P < 0.001, WMD=0.59, 95%CI: 0.06–1.12, P = 0.030). Conclusion:Laparoscopic surgery for right colon cancer, using the left margin of the SMA as the medial boundary for dissection is associated with a higher risk of postoperative complications, such as chyle leakage and diarrhea, than is using the superior mesenteric vein as the medial boundary. The durations of surgery and postoperative hospital stay are longer. SMA left margin dissection has significant oncological advantages, including a higher total number of harvested lymph nodes and of positive lymph nodes.

Objective:The study aimed to analyze the clinical and endoscopic characteristics of adult celiac disease (CD) to provide a scientific basis for more effective CD diagnosis and treatment.Methods:In this cross-sectional study, the clinical and endoscopic data of 96 adult CD patients treated in the Department of Gastroenterology of the People′s Hospital of Xinjiang Uygur Autonomous Region from March 2016 to December 2021 were retrospectively collected and analyzed.Results:A total of 96 CD patients were diagnosed, including 33 men and 63 women. The average age was 47±14 years (range, 18-81 years). The disease occurred mainly in the age group of 31-60 years. The median course of the disease was 2.0 (0.2-40.0) years. There were 41 (42.7%) classical and 55 (57.3%) non-classical CD patients. All patients with classical CD showed chronic diarrhea, often accompanied by abdominal pain (46.3%, 19/41), abdominal distension (17.1%, 7/41), anemia (65.9%, 27/41), and chronic fatigue (48.8%, 20/41). The main manifestations of non-classical CD were chronic abdominal pain (58.2%, 32/55), abdominal distension (32.7%, 18/55), anemia (40.0%, 22/55), and osteopenia/osteoporosis (38.2%, 21/55). Compared with non-classical CD, anemia developed more frequently in classical CD, and the difference was statistically significant ( P = 0.012). The incidence of complications in CD patients was 36.5% (35/96), and the main complications were thyroid disease (19.8%, 19/96), connective tissue disease (6.2%, 6/96), and kidney disease (6.2%, 6/96). There was no significant difference between classical and non-classical CD ( P>0.05). The frequency of endoscopic manifestations in CD patients was 84.4% (81/96). Duodenal bulb endoscopy showed nodular changes (72.9%, 70/96), grooved changes (10.4%, 10/96), and focal villous atrophy (9.4%, 9/96). The main manifestations of descending endoscopy were the decrease, flattening, or disappearance of duodenal folds (43.8%, 42/96), scallop-like changes (38.5%, 37/96), and nodular changes (34.4%, 33/96). Conclusions:Adult CD patients are mostly female. CD occurred mainly in the age group of 31-60 years. The clinical manifestations were mainly those of non-classical CD. Some patients often had other autoimmune diseases. Patients with characteristic endoscopic manifestations should be warned about the possibility of developing CD. Clinicians should strengthen the understanding of CD and reduce the related rates of missed diagnosis.

Objective:To investigate the clinical manifestations and pathological features of adult celiac disease in Xinjiang Uygur Autonomous Region.Methods:From January 2016 to December 2019, the clinical data of 943 patients with gastrointestinal symptoms such as chronic diarrhea, abdominal pain, abdominal distension and visited the People′s Hospital of Xinjiang Uygur Autonomous Region were collected. All patients tested for serum anti-tissue transglutaminase antibody inmunoglobulin A (tTG-IgA). And patients with positive serum tTG-IgA underwent gastroscopy and colonoscopy examination. To observe whether duodenal and ileal mucosal villi atrophy and histopathological examination was performed. Body mass index (BMI), hemoglobin, serum calcium, serum albumin level were compared between patients with and without celiac disease. T test and chi-square test were used for statistical analysis. Results:Serum tTG-IgA was positive in 30 patients, and 28 cases were finally diagnosed as celiac disease. The detection rate of celiac disease of Kazakh patients was higher than that of Uygur and Han patients (17.3%, 9/52 vs. 3.2%, 12/375 and 1.4%, 6/427), the detection rate of celiac disease of Uygur was higher than that of Han, and the differences were statistically significant ( χ2=7.65, 5.42 and 5.98, all P<0.05). The main clinical manifestations of 28 patients with celiac disease were weight loss or marasmus (71.4%, 20/28), iron deficiency anemia (67.9%, 19/28), persistent fatigue (57.1%, 16/28) and chronic diarrhea (53.6%, 15/28). The serum tTG-IgA level of patients with celiac disease was higher than that of patients without celiac disease ((131.97±64.58) CU vs. (7.58±1.92) CU), while the levels of BMI, hemoglobin, serum calcium and serum albumin were all lower than those of patients without celiac disease ((15.4±2.9) kg/m 2 vs. (23.8±3.4) kg/m 2, (110±28) g/L vs. (138±12) g/L, (1.70±0.20) mmol/L vs. (2.52±0.15) mmol/L, and (31.5±11.6) g/L vs. (48.2±7.3) g/L, respectively), and the differences were statistically significant ( t=2.473, 2.521, 2.641, 2.734 and 2.512, all P<0.05). Under gastroscopy all patients with celiac disease had atrophy of duodenal mucosal villi, which mainly appeared as nodular mucosal atrophy, grooves and fissure like changes, and villous atrophy was confirmed by histopathology. Conclusions:The detection rates of celiac disease in Kazakh and Uyghur in Xinjiang Uygur Antonomous Region are significantly higher than that of Han nationality. Celiac disease screening has a certain clinical significance.

Objective To investigate the impact and the associated parameters of malnutrition and inflammation status on hospitalization and mortality of maintenance hemodialysis (MHD) patients. Method A total of 118 MHD patients were included in the study with 1 year's follow-up.The malnutrition and inflammation parameters were compared between the hospitalized patients and out-patients.Cox's proportional hazard regression model was used to explore the malnutrition and inflammation parameters which could forecast the risk of hospitalization and mortality. Result The hospitalization rate of MHD patients with mild,moderate and severe malnuttition was 32.93％,56.67％ and 83.33％ respectively,and the mortality was 3.66％,6.67％ and 80.00％ respectively.The hospitalization rate of MHD patients with or without microinflammation status was 56.45％ and 46.43％,and the mortality was 14.29％ and 1.61％.Inpatients had a higher malnutrition-inflammation score(MIS,8.36 vs 5.86,P＜0.05) and subjective global assessment of nutrition (MQSGA,14.49 vs 12.88,P＜0.05),a lower creatinine level (886.83 μmol/L vs 991.76 μmol/L,P＜0.05 ) and a lower albumin level (38.57 g/L vs 40.27 g/L,P＜0.05) than out-patients.Inpatients also had a higher level of TNF-α (65.41 μg/L vs 59.76 μg/L,P＜0.05) than out-patients.Cox proportional hazard model analysis showed that MIS and TNF-α were associated with patient's first hospitalization risk. Conclusions For the MHD patients,the more severe the malnutrition and micro-inflammation status is,the worse the clinical outcome is.The higher levels of MIS and TNF-α result in greater risk of hospitalization.

OBJECTIVETo study the relationship between polymorphism of inducible Nitric Oxide Synthase (iNOS) gene and the susceptibility of intestinal type stomach cancer and stomach cardia cancer in Chinese people.

METHODSA community-based case-control study was designed. Ninety-three intestinal type of stomach cancer and 50 stomach cardia cancer patients with endoscopy and pathology diagnosis were identified as cases. Two hundred and forty-six controls served as controls.

RESULTSC-->T polymorphism was found in exon 16 of iNOS gene, which changed the coding amino acid from serine to leucine, and formed a recognition site identified by Tsp 509 I restriction enzyme (we called it C-->T polymorphism). The T allele gene frequency in the control group was 13.21%. No statistically significant difference was found between C-->T polymorphism alone and the increased susceptibility to intestinal stomach cancer or stomach cardia cancer. A significant type 2 multiplicative interaction was found in increasing both the risk of intestinal stomach cancer and stomach cardia cancer when both C-->T polymorphism and tobacco smoking exposure existed. An additive interaction model, which showed statistically significant difference, was found to increase only the risk of stomach cardia cancer when CagA antibody shared negative but C-->T polymorphism occurred.

CONCLUSIONC-->T polymorphism of iNOS gene was considered as one of the possible susceptible genes, which specifically increased the risk of tobacco-related but CagA negative types of intestinal stomach cancer and stomach cardia cancer.
