Objective To compare the image quality of portal venous system in the patients with live cirrhosis and portal hyper-tension using two different inj ection methods,so as to investigate the optimization of imaging techniques.Methods Single-phase in-jection (group A)or biphasic injection (group B)was applied by random on 40 patients for portal venous system vascular imaging, and subsequently image quality and technical advantages between the two groups were compared and analyzed respectively.Results 1.There was no significant difference in image quality between the two groups(P>0.05),while contrast agent dosage (90 mL)in group B is less than group A(100 mL).2.The CT value of Portal vein,liver parenchyma and P-L discrepancy in group B were slightly lower than those in group A,however,no statistical difference was noted(P>0.05).After 45 second,the P-L discrepancy of group B was larger than that of group A.The peak times of portal vein,liver parenchyma and the P-L discrepancy in group B were longer than those in group A(P<0.05).3.The graph of P-L discrepancy demonstrated:the threshold interval of P-L discrep-ancy in group B was longer than that in group A.Conclusion Biphasic inj ection methods could not only afford reliable imaging quali-ty on portal venous system vascular imaging in the patients with liver cirrhosis and portal hypertension,but also lead to a less total dose of contrast agent.Therefore,it could be used as an optimal choice of imaging technology for portal venous system vascular ima-ging.

Objective: To investigate the status of overweight and obesity and associated factors among primary and middle school students in Huzhou City, Zhejiang Province, so as to provide insights into formulating the prevention and control strategies for overweight and obesity in students. Methods: Primary and middle school students from 5 counties (cities, districts) of Huzhou City were selected by using stratified cluster random sampling method from September to November, 2023. The general information, dietary habits and exercise behaviors were collected using the Student Health Status and Influencing Factors Questionnaire. Height and weight were measured, and body mass index was used to analyze overweight and obesity in primary and middle school students. A multivariable logistic regression model was used to analyze the influencing factors of overweight and obesity. Results: A total of 7 573 students were surveyed, including 3 791 males (50.06%) and 3 782 females (49.94%). There were 2 754 primary school students (36.37%), 2 744 junior high school students (36.23%) and 2 075 senior high school students (27.40%). There were 2 166 students with overweight and obesity (28.60%), 1 186 students with overweight (15.66%), and 980 students with obesity (12.94%). Multivariable logistic regression analysis showed that gender (female, OR=0.546, 95%CI: 0.493-0.604), frequency of sweetened beverage consumption (once and more per day, OR=1.349, 95%CI: 1.102-1.650), and frequency of milk and milk products consumption (less than once per day, OR=0.742, 95%CI: 0.577-0.954) were the influencing factors for overweight and obesity in primary and middle school students. Conclusion The prevalence of overweight and obesity among primary and middle school students in Huzhou City is 28.60%, and is associated with gender, frequency of sweetened beverages and milk and milk products consumption.

Objective To investigate the dynamic changes of vascular endothelium secreted factors after oral fatty meal test and the correlation of the factors with blood lipid in elderly diabetic patients. Methods Thirty-six elderly diabetic patients (diabetic group) and twenty heahhy elderly subjects(control group) were selected into the study and received oral fatty meal test for 6 hours. Diabetic group was divided into three subgroups, including fasting hypertriglyceridemia subgroup, postprandial hypertriglyceridemia subgroup and postprandial normotriglyceridemia subgroup. Serum nitric oxide (NO), endothelin-1 (ET-1), plasminogen activator inhibitor-1 (PAl-1) and tissue plasminogen activator (t-PA) were measured before and after oral fatty meal test. Results (1) The level of serum NO was significantly increased and ET-1 was significantly reduced in control group 2 hours after oral fatty meal test and were returned to basal state 6 hours after the test. But in diabetic group, postprandial serum NO level were decreased and ET-1 were increased gradually and reached to the peak 6 hours after oral fatty meal test. The ratio of NO/ET-1 was lower in diabetic group than that in control group (P< 0.01). There were important differences among fasting hypertriglyceridemia subgroup, postprandial hypertriglyceridemia subgroup and postprandial normotriglyeeridemia subgroup(P<0.05 or<0.01). (2) The level of PAl-1 was increased and t-PA was decreased slightly 4 hours after oral fatty meal test in control and diabetic groups. Compared with control group, PAI-1/ t-PA obviously increased in diabetic group. Meanwhile, PAI-1/t-PA in fasting hypertriglyeeridemia and postprandial hypertriglyceridemia subgroups were significantly higher than that in postprandial normotriglyceridemia subgroup(P<0. 05 or<0.01). (3) In the diabetic group, TG was negatively correlated with NO and t-PA(r=-0.360 P<0.05; r=-0.649, P<0.01) and positively correlated with ET-1 and PAI-1(r=0.421,P<0.01;r=0.520,P<0.01). Conclusions The elderly diabetic patients suffer from the imbalance of vascular endothelium secreted factors. The postprandial abnormal TG metabolism may aggravate the change and further damage the vascular endothelial function.

The target protein that expression by inducing was collected. And with cell fusion method , the monoclonal antibodies were preparation. Then the mAb were detected by IHC. Results: The mAb ( clone 7C7 ) was detected and it found positive for the breast, uterine fibroid tissue, showed negative in colorectal cancer tissue, smooth muscle tissue, the goal of the claim were achieve. Conclusion: Finally, we found the method that prepare for mAb was far beyond our imagination. The result of IHC on different samples about mAb(7C7)obtained compliance with an-ticipation. Study on the difference between the PR-A and PR-B had significance.

Objective To explore CT,MRI findings of extraskeletal mesenchymal chondrosarcoma (EMC).Methods Imaging information of all 8 cases of EMC verified by pathology were retrospectively analyzed.Results The location of lesions included lower extremity in 4 cases,forearm in 1 case,trunk in 2 cases and right lung in 1 case.The CT examination was performed in 7 cases,and 5 cases contained different patterns of ring-and-arc,granular,clump or irregular streaky mineralization.Dense calcification was detected in 3 cases,and focal in 2 cases.The nonmineralized component had slightly lower attenuation on CT scans than adjacent muscle.Four cases of peripheral located EMC demonstrated isointense on T1 WI,and mixed signal intensity on T2WI.For the cases of fine and dense calcification in 2 cases,numbers of dot-like low-intensity signals were detected resembling “pepper sign”; while for the cases of focal mineralization in 1 case,the low intensity area was located centrally in the high intensity area.Heterogeneous enhancement was found both in the calcified and uncalcified areas.One case of central located tumor exhibited low and high intensity on T1 and T2 weighted images,and nodual enhancement was observed.Conclusion EMC has several characteristic imaging features,including various mineralization pattern,enhancement of calcified area and signal intensity,which might have diagnostic value for this rare tumor.

Objective:To study the risk factors and microbial spectrum for infectious complications for patients with biliary tract cancer after major hepatectomy with cholangiojejunostomy.Methods:Enrolled into this study were 78 consecutive patients (57 patients with perihilar cholangiocarcinoma, 17 with intrahepatic cholangiocarcinoma and 4 with gallbladder cancer), who underwent major hepatectomy with cholangiojejunostomy at Nanjing Drum Tower Hospital between September 2010 and March 2019. The clinical data were reviewed using multivariate analysis to find independent risk factors for postoperative infectious complications. Microorganisms isolated from bile and infected sites were determined to study the microbial spectrum.Results:A total of 45(57.7%) patients suffered from postoperative infectious complications. Male sex ( OR=7.765, 95% CI=1.895-31.815, P<0.05) was the independent risk factor, whereas increased preope-rative red blood cell (RBC) ( OR=0.151, 95% CI=0.038-0.592, optimal cut-off value=3.7×10 12/L) and increased total cholesterol (TC) on postoperative day (POD) 1 ( OR=0.227, 95% CI=0.083-0.626, optimal cut-off value=3.5 mmol/L) were protective factors (both P<0.05). The area under the receiver operating characteristic (ROC) curve was 0.805 (95% CI=0.707-0.902, P<0.05). 205 and 230 microorganisms were cultured respectively from 286 and 681 specimens which were collected from pre-/intraoperative bile and potentially infected sites. Staphylococcus, enterococcus, acinetobacter, klebsiella and pseudomonas were the most common pathogens on bile culture. The first 5 most frequently isolated microorganisms from the infected sites were enterococcus, staphylococcus, klebsiella, candida and xanthomonas. Sixteen (61.5%) of 26 patients had at least one pathogen being isolated from the infected sites with the pathogen being previously isolated in bile culture. Conclusions:Male sex were independent risk factors of infectious complications. Increased preoperative RBC and inreased TC on POD were proteetive factors. For patients without a positive bile culture, a third-generation cephalosporin can be considered as a prophylactic antibiotic. It is important to identify high-risk patients and monitor perioperative pathogens actively to prevent and to cure postoperative infectious complications.

Objective To compare the clinical outcomes of endoscopic nasobiliary drainage (ENBD) versus percutaneous transhepatic biliary drainage (PTBD) in patients with perihilar cholangiocarcinoma.Methods This retrospective case-control study was conducted on 55 patients with perihilar cholangiocarcinoma who were treated by of hepatobiliary and pancreatic surgeons at the Nanjing Drum Tower Hospital between December 2010 and August 2017.Results There was no significant difference in the effectiveness of the two drainage methods (P＞0.05).Morbidity after drainage was significantly higher in the ENBD group than the PTBD group (86.7％ vs 28.0％,P＜0.05).24 patients in the ENBD group developed postERCP pancreatic complications which included hyperamylasemia (n =20) and pancreatitis (n =4).All these patients responded well to conservative treatment.A patient in the PTBD group developed catheter tract tumor implantation.There were no significant differences in the surgical outcomes and in the different Clavien-Dindo grades of complications (P＞0.05).Abdominal infection after surgery was more common in the PTBD group than the ENBD group (64.3％ vs 26.3％,P＜0.05).Conclusion As PTBD caused catheter tract tumor implantation and increased the incidence of abdominal infection after surgery,ENBD was recommended for patients with perihilar cholangiocarcinoma treated in a tertiary medical center.

Objective: To investigate the clinical effect of bile reinfusion combined with enteral nutrition support before surgery for hilar cholangiocarcinoma. Methods: A retrospective analysis of patients with hilar cholangiocarcinoma who underwent surgical treatment at Nanjing Drum Tower Hospital Hepato-biliary-pancreatic Surgery Department from July 2010 to August 2017 was completed.A total of 52 cases were finally enrolled in our study.All the patients included, on the basis of whether they received preoperative drainage and bile reinfusion, were divided into non-drainage group(n=15) and drainage group(n=37). Differences of clinical indicators, including operation time, intraoperative bleeding and serum liver function index levels at day 1, 3, 7 postoperative, postoperative complications(liver failure, biliary fistula, pleural effusion, peritoneal effusion, abdominal cavity infection, death in hospital), tumor classification, R0 resection, postoperative hospitalization time between the 2 groups were analyzed. At the same time, in the drainage group, patients were divided into non-enteral nutrition subgroup(n=13) and enteral nutrition subgroup(n=24) according to whether they received enteral nutrition before operation. The normal distribution data of the group was statistically analyzed by independent sample t test, the non-normal distribution data of the group was statistically analyzed by rank-sum test. The count data was statistically analyzed by non-calibration and correction of the square test. Results: There was no statistically significant difference in general infomation such as age, gender, and serum liver function between non-drainage group and drainage group(P>0.05). There was no statistically significant difference in general information such as age, gender, and serum liver function between non-enteral nutrition group and enteral nutrition group(P>0.05). The rate of vascular resection and reconstruction(33.3%) and operating time(10.8(2.2)h) in drainage group were both higher than those in non-drainage group(6.7% and 8.3(3.0)h), the differences were both statistically significant(χ²=4.397, Z=1.595; both P<0.05). The level of AST at the 7th day after surgery in drainage group(32.8(17.3)U/L) was significantly lower than that in non-drainage group(55.0(64.7)U/L), the difference was statistically significant(Z=-2.212, P<0.05). The level of TBil at 1st day after surgery in drainage group(43.6(91.2)μmol/L) was lower than that in non-drainage group(91.2(188.4)μmol/L), the difference was statistically significant(Z=-2.150, P<0.05). The rate of pancreatoduodenectomy(25.0%) and average operating time(11.1(1.3)h) in the enteral nutrition group were both higher than those in the non-enteral nutrition group(0, 9.0(2.6)h). The differences were both statistically significant(χ²=3.879, Z=-2.693; P<0.05). The average level of AST at the 1st day after surgery in enteral nutrition group(396.4(268.3)U/L) was significantly lower than that in non-enteral nutrition group(642.5(341.1)U/L), the difference was statistically significant(Z=-2.483, P<0.05). The average level of TBil at the 1st, 3th day after surgery in enteral nutrition group(38.8(21.5)μmol/L and 30.0(25.6)μmol/L) were both lower than those in non-enteral nutrition group(60.9(75.2)μmol/L and 46.5(50.0)μmol/L), the differences were both statistically significant(Z=-2.416, -2.026; P<0.05). The level of CRP at 1st, 3th day after surgery((41.9±31.1)mg/L, (50.8±31.4)mg/L)in enteral nutrition subgroup was lower than that in non-enteral nutrition subgroup((64.4±33.6)mg/L, (74.1±35.3)mg/L), the differences were both statistically significant(t=1.456, 1.675; P<0.05). Conclusion Based on the present study , there is no effective improvement on postoperative recovery using bile reinfusion combined with nutrition support before R0 resection of hilar cholangiocarcinoma.
