Objective To investigate the infection situation of intestinal nematodes and knowledge about the prevention and control of intestinal nematodiasis,so as to explore the effective control measures in Jingjiang City. Methods The towns where more floating people lived were randomly selected and the infection situation of intestinal nematodes was investigated with Kato-Katz method,and the residents'awareness of the prevention and control of nematodiasis was surveyed with questionnaires. Re-sults From 2013 to 2015,totally 4555 local residents and 2278 floating people were investigated in Jingjiang City. The infec-tion rate of intestinal nematodes was 0.29%(13 cases)in the local people,while the rate was 0.75%(17 cases)in the floating people,and the difference was significant(χ2=7.380,P<0.01). The differences of the intestinal nematode infection rates be-tween sexes in both local residents and floating people were not significant(χ2=0.010,0.048,both P>0.05). The awareness rate of intestinal nematodiasis prevention and control of the local residents was significantly higher than that of the floating peo-ple(χ2 =9.649-164.533,all P<0.01). Conclusion The floating people is the focus of intestinal nematodiasis control,and the health education of ancylostomiasis control should be strengthened in Jingjiang City.

Objective To observe the clinical value of indocyanine green retention rate at 15 minutes (ICGR15) in the evaluation of hepatic functional reserve. Methods A total of 185 patients with liver disease, including 45 cases of liver failure, 90 cases of cirrhosis (child A, B and C, respectively), 20 cases of acute hepatitis, 30 cases of chronic hepatitis (mild, moderate). Expression levels of ICGR15 were compared between groups. Values of ICGR15, total bilirubin (TBIL), albumin (ALB), blood coagulation time (PT) were compared before treatment and one month after treatment in hepatic failure group. Levels of alanine aminotransferase (ALT), aspertate aminotransferase (AST), TBIL and ICGR15 were compared before treatment and 1 month after treatment in acute hepatitis group. Results Levels of ICGR15 (%) were 56.3±14.7, 28.9±9.6, 22.4±6.8 and 13.7±2.3 in liver failure group, liver cirrhosis group, acute hepatitis group and chronic hepatitis group, which showed a gradual downward trend (F=125.317, P<0.05). Among them, the levels of ICGR15 (%) were 17.3±5.4, 25.7±7.5 and 34.5±7.3 in Child A, B and C groups of liver cirrhosis group, which showed a gradual upward trend (P<0.05). After one month treatment, levels of TBIL, PT and ICGR15 were significantly lower than T helper 17 cells; intima-media thickness before the treatment in liver failure group. The levels of ALT, AST, TBIL and ICGR15 were significantly lower after treatment than those before treatment in acute hepatitis group (P<0.05). Conclusion ICGR15 can reflect hepatic reserved function, which is not affected by the application of albumin and fresh plasma, and makes up the deficiency of PT and ALB detection.

Objective To investigate the changes in pentane (marker of lipid pemxidation) concentuation in the expired air induced by hepatic ischemia-reperfusion(IR)injury in rabbits.Methods Thirty healthy male Japanese white rabbits weighing 2.4-3.0 kg Were randomly divided into 2 groups(n=15 each):group Ⅰ sham operation and group Ⅱ hepatic IR.Anesthesia was induced with 3% pentobarbital 30mg/kg iv and maintained with The animals were tracheostomized and mechanically ventilated.Femoral artery and vein were cannulated for BP monitoring and blood sampling.Hepatic blood flow was occluded for 25 min followed by 180 min reperfusion.The expired air was collected before(baseline,T0)and at 1,10 and 25 min of ischemia and at 1,10,25,60,120 and 180 rain of reperfusion (T1-9) for determination of pentane concentration which was extracted by solid phase micro-extraction (SPME) and detected by gas chromatography-mass spectrography(GC-MS).Blood samples were also taken at the above time points for measurement of serm ALT,AST and SOD activities and MDA concentration.The animals were killed at the end of 180 min reperfusion.Liver specimens were obtained for histology.Results There was no significant difference in age,body weight,MAP and HR between the two groups.There was no significant change in pentane concentration in the expired air and the ALT,AST and SOD activities and MDA concentration at all time points as compared with the baseline in sham operation group.In IR group the pentane concentration in the expired air was significantly increased at T4,5 and the ALT and AST activities and MDA concentration were significantly increased and SOD activity was significantly decreased at T7-9 as compared with the basehne and the sham operation group.Conclusion The pentane concentration in the expired air can reflect the occurrence of lipid peroxidation during hepatic IR injury.

Objective To discuss the clinical features of HbeAg-negative chronic hepatitis B patients associate with non-alcoholic fatty liver disease (NAFLD), to value the effect of combining treatment on fatty liver influence and antivi-ral therapy. Methods Nighty eight chronic hepatitis B patients with non-alcoholic fatty liver disease (NAFLD) (Liver pa-thology G≥2 or S≥2,HBV DNA>1 × 105 copies/mL), were observed and given antiviral therapy with interferon alpha 1 b for 24 weeks. These patients were divided into combined treatment group (55 cases treated with interferon alpha 1 b combined with Jian Gan Jiang Zhi pills) and control group (43 cases treated with interferon alpha 1 b) in accordance with random num-ber table. All these patients took Leucoson to prevent blood cells reduction. The combined treatment effect was analyzed by observing and comparing biochemical serum change and HBV DNA negative conversion ratio between two groups. Re-sults After 24 weeks of antiviral therapy in Chronic hepatitis B patients with negative HBeAg associated with NAFLD, ALT and AST decreased significantly in both treatment group and control group. And this change is more obvious in treat-ment group than in control group. TC and TG in treatment group and TC in control group were also dropped with treatment (P<0.05). There is significant difference on HBV DNA negative conversion ratio between treatment groupand control group (98.2%vs 86.0%,P<0.05). Conclusion The combination of antiviral treatment and anti fatty liver treatment can obviously improve liver function and blood lipids, increase negative conversion ratio of HBV DNA for chronic hepatitis B patients asso-ciated with NAFLD.

Objective To investigate the prognostic factors for clinical relapse in chronic hepatitis B (CHB) patients with hepatitis B e antigen (HBeAg) seroconversion after drug withdrawal and to establish a prognostic model.Methods Totally 201 CHB patients with HBeAg seroconversion after the antiviral therapy were enrolled.The epidemiological variables including age, gender and family history of hepatitis B were collected.Liver function and hepatitis B virus (HBV) DNA level one week before initiation of antiviral therapy, hepatitis B surface antigen (HBsAg) level at the time of drug withdrawal and the duration of antiviral therapy after HBeAg seroconversion were analyzed.The clinical relapse after 48 weeks of drug withdrawal was followed up.The patients were divided into relapse group and non-relapse group according to clinical variables at 48 weeks after drug withdrawal.The counting data were analyzed by chi-square test and the measurement data were analyzed by t test.The Logistic regression model was used to determine the prognostic factors for clinical relapse.The receiver operating charactenstic (ROC) curve was constructed to assess the performance of the prediction model.Results The clinical relapse rate was 16.42% (33/201) after 48 weeks of drug withdrawal.By multivariate analysis, age, the duration of antiviral therapy after HBeAg seroconversion and HBsAg level at the time of drug withdrawal were independent predictors (χ2=14.546, t=3.202, t=3.286, respectively;all P<0.05).The regression model Logit (P)=1.220×age-0.040×the duration of antiviral therapy after HBeAg seroconversion +0.004×HBsAg level at the time of drug withdrawal-5.426.The sensitivity and specificity with the cut-off value of-0.860 were 73.10% and 90.40%, respectively.Conclusions Age, the duration of antiviral therapy after HBeAg seroconversion and HBsAg level at the time of drug withdrawal are independent predictors for clinical relapse 48 weeks after drug withdrawal in CHB patients with HBeAg seroconversion after antiviral therapy.

Objective To investigate the first medical contact to balloon ( FMC2B) time in our center and to identify the influencing factors .Methods This is a retrospective study conducted in the heart center of Beijing Luhe Hospital . A total of 140 patients undergoing primary percutaneous coronary intervention ( PCI) were enrolled between July 2013 to September 2014.Demographic data , clinical risk factors and the emergency process were evaluated .All the patients were categorized into 2 groups including:the conformed group ( patients with FMC2B<120 min for non-PCI-capable hospital and <90 min for direct arrival at Luhe hospital, n=59) and the unconformed group (n=81).Multivariant regression aralysis was done to analyse factors influencing FMC 2B time.Results Among the enrolled 140 patients, 58 patients were initially seen in a non-PCI-capable hospital , 31 patients were directly sent to Luhe hospital by ambulance and 51 patients arrived by themselves.The median FMC2B time was 106.16 min (interquartile range [ IQR ]: 77.37 -165.52 min ) and 42.1% ( 59/140 ) of the patients achieved the current recommended FMC2B time.In a multivariate logistic analysis , FMC to electrocardiographic ( ECG) within 10 min ( OR=5.61 , 95% CI 1.91-16.88 ) , admission during normal working hours ( OR=5.11 , 95%CI 1.88-13.85 ) , patient′s education level of high school or above ( OR=4.16 , 95%CI 1.53-11.34 ) , awareness of heart diseases ( OR =2.58, 95% CI 1.13 -5.91 ) were predictors of improving FMC2B. Transfer for primary PCI (OR=0.37, 95% CI 0.15-0.92) increased FMC2B.Conclusions Less than half of the patients with primary PCI achieved the goal of guidelines′recommended FMC2B time.Initial ECG, admission during normal working hours , patient′s education level and awareness of heart diseases and transfer for primary PCI are the independent predictors of FMC 2B time.

Objective To investigate the impact of optical coherence tomography(OCT) imaging on physician decision-making during primary percutaneous coronary intervention(PCI) in patients with ST-segment elevation myocardial infarction (STEMI). Methods From January 2016 to May 2017, OCT was performed in 100 cases pre- and post- primary PCI. The pathogenesis of myocardial infarction was determined and immediate effect of PCI evaluated by OCT. Clinical outcome during a 12-months follow up was analyzed. Results The data from 17 patients were excluded for further study due to poor OCT images quality. The rates of plaque rupture, plaque erosion, calcification nodules, stent malapposition and coronary spasm were 65.1％(54/83), 26.5％(22/83), 3.6％(3/83), 2.4％(2/83) respectively among the remaining 83 patients with sufficient OCT quality images. of the overall rate of stent malposition, tissue prolapse and incomplete stent expansion was 21.7％(18/83). The incidence of edge dissection was 19.3％(16/83), and among them 2 patients required treatment with stent implantation. Among the 17 patients without stenting:coronary spasm were found in 2 cases, thrombus overload in 1 case after thrombus aspiration, plaque rupture in 7 cases , plaque erosion in 4 cases and stent malposition in 3 cases. One patient died in hospital for cardiogenic shock and one patient had subacute stent thrombosis . There were no major adverse cardiac events occurred in the remaining patients during the (11.0±4.0) months of follow-up. Conclusions OCT can identify nonoptimal stent deployment in approximately one-fourth of STEMI patients undergoing primary PCI, thus providing preliminary guidance to the physician for further mangement.

Objective To investigate the clinical value of re-using ultrafiltrated and concentrated ascites fluid for refractory ascites in patients with hepatitis B cirrhosis. Methods A retrospective study was conducted, one hundred and thirteen patients with intractable ascites (all patients received intraperitoneal reinfusion of ultrafiltrated and concentrated ascites fluid therapy) admitted to the Department of Gastroenterology of No.254 Hospital of the Chinese People's Liberation Army from December 2013 to November 2016 were enrolled and assigned as the study group, fifty-two patients with intractable ascites admitted in the same period as above group in this hospital without undergoing above ascites fluid reinsfusion were served as the control group. Both groups were given conventional therapies, including measures for hepatoprotection, increase of plasma osmotic pressure, correction of hypoproteinemia (intravenous injection albumin 10 g, 3 times a week), reduction of portal venous pressure (octreotide 0.2 mg, q8 h), improvement of microcirculation, correction of water and electrolyte balance disorders, diuresis (furosemide 100 mg/d), etc. On the basis of the above conventional treatment, the system with ascites ultrafiltration, concentration and reinfusion into abdominal cavity was applied to carry out the concentrated ascites fluid reinfusion therapy in the study group. The relieve of abdominal bloating, conscious, blood pressure, 24-hour urine output, endogenous creatinine clearance rate (CCr), serum potassium ion (K+), serum sodium ion (Na+), ascites albumin quantity, serum albumin levels before treatment and after treatment for 1 week, abdominal infection situation after treatment for 1 week were observed in the study group. The difference in incidence of abdominal infection between the study group and control group (at the end of 12 weeks after treatment) was compared. Results In the study group, after treatment, the patients with abdominal bloating had different degrees of relief, 24-hour urine output was increased compared with that before treatment (mL: 1291.3±123.4 vs. 1265.0±61.5, P = 0.051), no cases with conscious changes, blood pressure instable. There were no statistical significant difference in blood K+ and Na+ (P > 0.05). And ascites albumin concentration was increased compared with before treatment (g/L: 19.1±2.9 vs. 17.2±4.1, P = 0.000); 1 week after treatment, CCr was significantly higher than that before treatment (μmol/L: 71.2±8.7 vs. 56.1±5.4, P = 0.000); serum albumin was increased after 3 times of treatment in 1 week (g/L: 25.7±4.4 vs. 24.6±3.0), but the difference was not statistically significant (P = 0.054). No abdominal infection occurred within 1 week after treatment were observed in patients of study group. There was no statistical significant difference in the incidence of abdominal infection between the study group and control group in 12 weeks after treatment [9.7% (11/113) vs. 13.6% (7/52), P = 0.476]. Conclusions The re-using of ultrafiltrated and concentrated ascites fluid can effectively relieve the abdominal bloating symptom, improve CCr, be beneficial to the re-use of ascites albumin, and does not increase the incidence of abdominal infection within 12 weeks after the therapy, therefore the treatment has relatively high therapeutic value for intractable ascites in patients with hepatitis B cirrhosis.
