In order to strengthen the management of disinfection quality of endoscopes, Quality Control Center of Digestive Endoscopy and Nosocomial Infection Control Center of Yunnan Province investigated the diagnosis, treatment, cleaning and disinfection conditions and disinfection quality of digestive endoscopes in some medical institutions of Yunnan Province by web questionnaire from April to May in 2019, and 277 valid questionnaires were finally obtained. SPSS 19.0 statistical software was used to analyze the influencing factors of cleaning and disinfection process and the infection control implementation of digestive endoscopes in 227 secondary and tertiary hospitals. The results showed that the number of decontamination people who had received systematic training in Yunnan Province was significantly lower than that in other areas of China. The hospital level, the number of decontamination personnel, and decontamination methods affected the implementation of cleaning and decontamination process and infection control, while the allocation of decontamination supplies had no effects. It is important to establish an effective mechanism for the normalized implementation of cleaning and disinfection of digestive endoscopes.

Objective To investigate the prenatal diagnosis and postnatal clinical outcomes of fetal congenital choledochal cyst (CCC) to improve the recognition and treatment of fetal CCC.Methods Clinical data of 23 cases of fetal CCC which were diagnosed during routine prenatal ultrasonic examination in Jinhua Municipal Central Hospital from June 2009 to May 2015 were retrospectively analyzzed. Maternal age, gestational age at diagnosis of CCC, location and size of cyst, postnatal examination, age at operation and follow-up outcomes were recorded and statistically analyzed by Wilcoxon rank-sum test.Results (1) Among the 23 cases, six (26%) were terminated and the rest 17 continued their pregnancies (74%). (2) Results of the prenatal ultrasonography of the 23 cases indicated that hepatic portal cysts were closely related to hepatic portal veins or arteries. Six of the cysts communicated with gall bladder and eight connected to intrahepatic bile duct. The maximum diameter of the cysts in the 23 cases was 16.0-31.0 mm, averagely (24.7±3.7) mm. The maximum diameter of cysts diagnosed in the third trimester was significantly larger than that in the second trimester [ 27.0 (22.0-31.0) vs 23.0 (21.0-25.0) mm,Z=-2.134,P<0.05]. (3) Among the 17 cases of continued pregnancy, one underwent cesarean section at 35+ weeks of gestation and 16 delivered at term with the average gestational age at delivery of (38.2±1.1) weeks. All neonates were re-examined by abdominal ultrasound at 1-2 postnatal weeks and confimed prenatal diagnosed of CCC. (4) The 17 neonates were re-examined by abdominal ultrasound during the second postnatal week and the results showed that cyst size remained the same in four, decreased in one and gradually increased with the gestational age in 12 neonates. Among the 16 cases of confirmed CCC, 12 received surgery, including 11 (Ⅰa, 6;Ⅰc, 3;Ⅳb, 2) within one year-old and one (Ⅰc) around 18 months old. The prognosis was uneventful. Four out of the 16 cases rejected surgical operation and were followed up in outpatient. One neonate was diagnosed with congenital biliary atresia and transferred to Children's Hospital for operation.Conclusions When fetal abdominal cyst presented with hepatic portal cyst which communicates with gallbladder or intra-hepatic duct in ultrasonography, a congenital choledochal cyst should be taken into consideration by excluding the possibility of biliary atresia in the first place. Surgery for CCC infants without symptoms or signs is suggested to be performed around three months after birth. The postoperative prognosis of CCC is favorable, so termination is not recommended for gravidas with fetal CCC in prenatal consultation.

OBJECTIVETo investigate the relationship of alcohol intake and hepatocellular carcinoma among patients with hepatitis B virus infection.

METHODSA total of 553 patients with HCC and 160 control subjects affected with hepatitis B virus were recruited. Serum virology, serum biochemistry, as well as demographic information were studied. Finally, risk factors were selected by stepwise Logistic regression analyse. Odds ratios (ORs) were estimated for each risk factor. According to alcohol intake, HCC patients were divided into three groups,then to observe the differences between them.

RESULTSElevated AST, GGT, ALP and AFP levels were seen more frequently in the HCC case groups compared to control group (P < 0.05). Multivariate analysis revealed that heavy alcohol use, smoking, positive family history of liver cancer is associated with HCC development among patients with hepatitis B virus infection. Significantly increased risk was found among patients for heavy alcohol use [A = 2.66 (2.01-3.50)] and for smoking [A = 2.51 (1.66-3.80)] and for positive family history of liver cancer [A = 1.64 (1.04-2.59)]. Compared to patients who did not have alcohol use, elevated GGT and ALP were seen more frequently in patients who had alcohol use either mild or heavy (P < 0.05).

CONCLUSIONSHeavy alcohol use, smoking, positive family history of liver cancer is positive correlation with HCC development among patients with hepatitis B virus infection in China. In patients with hepatitis B virus infection who also has history of heavy alcohol, the most risk factor of HCC is hepatitis B virus infection, not alcohol.

OBJECTIVETo investigate if glutamine (Gln) reduces intestinal bacterial translocation in acute hepatic failure (AHF) in rats and its mechanisms.

METHODSAcute hepatic failure model in rat was established by intraperitoneal injection of galatosamine. The rats were randomly divided into 4 groups: the normal control group (A), prevention and treatment group (B), treatment group (C), and model group (D). The rats in groups A and D were fed with normal saline. Two days before intraperitoneal injection, the rats in group B were fed with Gln and those in group C were fed with Gln 24 hours after injection. After 4 days of treatment, the rats were sacrificed and pathological scores of liver were assessed. The percentage of intestinal bacterial transloaction and bacteria in mesenteric lymph nodes (MLN) were measured. The villus height, crypt depth of ileum mucosa were analyzed. The levels of serum diamine oxidase (DAO) were measured.

RESULTSThe liver pathological scores of groups B and C were significantly lower than those of group D. The frequency of the bacteria found in MLN was significantly lower in group B compared with group D. The levels of DAO in blood were significantly lower in groups B and C than that of group D, and the level was significantly lower in group B than in group C. The villus height and crypt depth of the mucosa were significantly greater in group B and group C than in group D, and greater in group B than in group C.

CONCLUSIONThe results of the present study show that Gln can reduce the occurrence of the intestinal bacterial translocation in AHF in rats by improving the function of intestinal barrier.

OBJECTIVETo investigate the effect of extract of ginkgo biloba leaf (EGb) during the formation of HBV-related hepatocellular carcinoma (HCC).

METHODS99 HBV transgenic mice were randomly divided into control group, high-dose group, low-dose group. High-dose group and low-dose group were intraperitoneal injected 35mg/(kg x d) and 17.5 mg/(kg x d) of the shuxuening injection. Control group without special treatment. The serological markers and immunohistochemical markers in liver tissue will be done at the first 12 months and 18 months.

RESULTS(1) HBV transgenic mice can be found HCC at the 18 months. The incidence of HCC was lower in high-dose group and low-dose group, there was statistically different among the three groups. (2) The semi-quantitative scoring of liver HBx expression was highest in the control group at the 12 months. The semi-quantitative scoring of liver HBx, p53 and Bcl-2 expression was highest in the control group at the 18 months. They all appeared statistically different among the three groups. (3) Spearman correlation analysis showed that HCC incidence and liver tissue HBx, p53, Bcl-2 expression was a certain degree of positive correlation, r was 0.536, 0.487 and 0.403, P < 0.05.

CONCLUSIONEGb can reduced the incidence of the HCC with HBV transgenic mice. The reason may be that the EGb can reduce liver HBx, p53, Bcl-2 protein expression in the HBV transgenic mice.

OBJECTIVETo analyze the treatment strategies and prognosis of squamous cell carcinoma of cervical lymph nodes from an unknown primary site (SCCUP).

METHODSA total of 125 cases with SCCUP was retrospectively analyzed from January 2001 to December 2011. Ninety-seven of the cases were treated with neck dissection (ND), including 24 with classic radical ND, 62 with modified ND and 11 with extended radical ND. Of 125 cases with SCCUP, 72 cases were supplemented with radiotherapy and 52 cases with chemotherapy. Radiotherapy was applied with extensive field in 36 cases, bilateral neck in 15 cases, and ipsilateral neck in 21 cases. The patients were followed up and the Kaplan-Meier method was used to calculate survival curves. Cox's analysis and logistic regression were used to evaluate the prognosis factors for SCCUP.

RESULTSThe 5-year overall survival rate and disease free survival rate of the cohort were 66.2% and 60.0%, respectively. The median survival time was 70 months. Cox's analysis showed N-stage, extracapsular spread, bilateral neck metastasis and ND were independent prognostic factors for SCCUP. Logistic regression suggested that N-stage was the main factor for nodal recurrence or uncontrolled. The primary tumor sites emerged in 27 patients (21.6%) within 3 - 96 months after treatment (median time was 15 months), but only 4 patients (11.1%) existed in 36 cases underwent radiotherapy with extensive field.

CONCLUSIONSN-stage and extracapsular spread are two major factors influencing the prognosis of SCCUP. ND may improve the locoregional control and long-term survival.
