OBJECTIVE: To compare the efficacy and safety of different antiviral and antifibrotic regimens in patients with chronic hepatitis B (CHB) and hepatic fibrosis and the incidence of hepatocellular carcinoma (HCC) associated with these therapies. METHODS: A total of 840 patients with CHB and concurrent hepatic fibrosis, who received antiviral therapy in Nanfang Hospital between June, 2010 and June, 2018, were enrolled in this follow-up cohort study. The patients were assigned to 3 cohorts matched for gender, age (difference≤5 years), HBeAg status and liver stiffness measurement (LSM) for treatment with one of the 3 antiviral drugs, namely entecavir, tenofovir dipivoxil and adefovir dipivoxil; each cohort was divided into 2 groups, with one of the groups having a combined treatment with Fufang Biejiaruangan tablet. The cumulative negative conversion rate of HBV DNA, normalization rate of ALT, hepatic fibrosis regression and the incidence of HCC were compared among the 3 cohorts and across the 6 groups at 144 weeks. RESULTS: A total of 749 patients were available to follow-up at 144 weeks. Compared with the baseline data, the cumulative negative conversion rate of HBV DNA increased gradually and the abnormal rate of ALT decreased significantly over time during the treatment in all the 6 groups (all < 0.001). Compared with the any of the antiviral drugs used alone, the combined treatments all resulted in significantly better antifibrotic effects (χ=11.345, χ=10.160, χ=6.358; all < 0.05). At 144 weeks, the incidence of HCC were 2.2%, 1.7%, 1.7% and 3.3% in enecavir group, enecavir with Biejiaruangan tablet group, adefovir group, and adefovir with Biejiaruangan tablet group, respectively, showing no significant difference between the two cohorts (4 groups; χ=6.813, =0.138). None of the patients in the 2 groups with tenofovir treatment had HCC by the end of the observation. CONCLUSIONS Antiviral therapy combined with antifibrotic therapy can effectively reverse hepatic fibrosis and reduce the incidence of HCC in patients with CHB; among the 3 antiviral drugs, tenofovir dipivoxil can be a better option for reducing the incidence of HCC in these patients.

Objective To analyze the death status of children ≤ 5 years old in Jiaxing City from 2013 to 2017,and to provide scientific and effective measures of decreasing the children mortality and ensuring the health of children.Methods Death surveillance data of children ≤5 years old was obtained from monitoring network covering the whole city of maternal and child health information systems and the relevant maternal and child health statistics.The mortality rate,the sequence and changing trend of main death causes,prenatal health services of children ≤5 years old in Jiaxing City from 2013 to 2017were analyzed.Results From 2013 to 2017,there were 2 788 cases death of children ≤5 years old in Jiaxing City.The neonatal mortality rate (NMR),infant mortality rate (IMR),≤5 years old children mortality rate(U5MR) in Jiaxing City were 2.33‰,3.52‰ and 4.83 ‰,respectively.The mortality rates of all ages showed a declining trend year by year (x2NMR =19.641,P＜0.001;x2IMR =31.705,P ＜0.001;x2U5MR =48.294,P ＜0.001).There were significant differences in the mortality between the lower local and the migrant children (x22013 =26.16,x22014 =18.45,x22015 =27.72,x22016 =14.49,x22017=24.19;P＜0.001).The top two causes of death in children ≤ 5 years old were drowning,premature birth and low birth weight.The top two causes of death in infants and newborns were premature birth,low birth weight and other congenital anomalies.In the recent five years,49.60％ of children ≤5 years old died in the hospital.At the same time,the proportion of deaths on the way and at home was 15.64％ and 34.76％ respectively.Although there was a gap in the level of prenatal health services between local and mobile children,the gap has been declining year by year.Conclusions The key measures to decrease the mortality rate of children under 5 years old in Jiaxing City include strengthening the management of pregnancy care and high-risk pregnancy;paying attention to tertiary prevention and doing a good job in monitoring birth defects such as prenatal screening;enhancing safety education and child supervision for parents of children in 1-4 years old;reinforcing the construction of maternal and child health professional team and the technical training of newborn resuscitation techniques such as neonatal asphyxia recovery technology;intensifying the health-care and management of migrant children and improving the ability of parents to utilize child medical service.

To study the role and molecular mechanism of epigallocatechin gallate (EGCG) in reversing drug-resistance to 5-fluorouracil (5-FU) in gastric cancer drug-resistant cell line SGC-7901/5-FU.

METHODSDrug-resistance gastric cancer cell line (SGC-7901/5-FU) was established by high doses of repeated impact joint drug concentration increment methods. The cell viability of the parent cell line and the drug-resistance cell line were determined by standard MTT assay. Cell survival rate of drug-resistance was calculated by the formula [(Aof the treatment group / Aof the control group) × 100%]. Cell half inhibitory concentration (IC) and resistance index (RI) were calculated by the Graphpad prime 6.0 software(RI=ICvalue of drug-resistance cells / ICvalue of parent cells). The apoptosis rate of SGC-7901/5-FU cells was quantified by flow cytometry after staining with annexin-V and PI. Western blot was used to detect the protein expression of drug-resistance-related proteins (ABCG2, P-gp, MDR-1 and GST-π) and apoptosis-related proteins (PARP, Survivin, Bax and bcl-2).

RESULTSICvalue was significantly increased in drug-resistant cells compared with parental cells [(64.7±3.9) mg/L and (4.1±0.3) mg/L, respectively, t=26.46, P=0.000], and the RI was 15.6. Proliferation activity in the drug-resistant cells was higher than that in parental cells at different 5-FU concentrations (all P<0.05). In drug-resistant cells, the ICvalue of 5-FU combined with EGCG group obviously decreased compared with 5-FU group [(7.3±0.1) mg/L and (63.1±1.4) mg/L respectively, t=40.84, P=0.000], and the RI was 0.12. Proliferation activity in drug-resistant cells was significantly decreased after EGCG treatment at different 5-FU concentrations (all P<0.05). Cell apoptosis rates in control group, 5-FU group, EGCG group and 5-FU combined with EGCG group were (3.0±1.0)%, (7.0±1.3)%, (6.0±1.2)% and (18.0±1.4)%, while apoptosis rate in 5-FU combined with EGCG group was significantly higher than those of other 3 groups(F=129.5, P=0.000). Western blot revealed that after EGCG treatment, the expression levels of drug-resistance-related proteins (ABCG2, P-gp, MDR-1 and GST-π) in the drug-resistant cell line SGC-7901/5-FU decreased significantly; the expression levels of apoptosis marker protein PARP and pro-apoptotic protein Bax increased significantly; and the expression levels of anti-apoptotic protein Survivin and Bcl-2 decreased significantly (all P<0.05).

CONCLUSIONEGCG can reduce the resistance of gastric cancer resistant cell line SGC-7901/5-FU, whose role may be via the inhibition of the expression of drug-resistance-related proteins, and the elevation of the protein expression ratio of PARP/Survivin and Bax/Bcl-2.

OBJECTIVE: To evaluate the curative effect and safety of endoscopic full-thickness resection (EFR) in the treatment of gastric tumor originated from the muscularis propria.
 METHODS: Clinical data were collected from 34 patients, who underwent EFR of gastric tumor originated from muscularis propria, to observe the resection rate and complications from November 2012 to August 2014.
 RESULTS: Of the 34 patients, 15 were male, 19 were female, with the age of 38.3-70.6 (52.3±4.3) years old. The lesions of 25 patients located in the fundus of stomach and the rest was in the gastric body. EFR was successfully performed in the 34 patients with no need for surgery. The complete resection rate was 100%. Lesion diameter ranged from 1.0 to 5.0 (2.8±1.2) centimeters. The operation time was 50-100 (76.5±18.2) min. Patients with pneumoperitoneum were relieved after abdominal puncture exhaust, without post-operation bleeding and perforation. The hospitalization duration was 3-5 (3.6±0.8) days. Except 1 case, the remaining 33 cases were spindle cell tumors, consistent with the results of immunohistochemistry. The risk for two lesions with 4.5 cm and 5.0 cm was moderate. The risk of invasion was low or very low in the remaining 31 cases. Among them, 2 stromal tumors near the cardia showed a differentiation tendency toward smooth muscle. No lesion residual or recurrence happened during the follow-up period (range 5-23 months) in 34 cases. 
 CONCLUSION EFR is a safe and effective method for gastric tumor originated from muscularis propria.

OBJECTIVE: To study the correlation of CD44 with epithelial-mesenchymal transition(EMT) and metastasis in nasopharyngeal cancer cells, and explore the possible mechanism of CD44 regulates EMT and metastasis in nasopharyngeal cancer cells. METHOD: The CD44 and EMT-associated proteins in 5-8F and 6-10B nasopharyngeal cancer cell lines were assayed by Western blotting. The erasion trace test was performed to observe the migratory ability of 5-8F and 6-10B nasopharyngeal cancer cells. Using lipid-mediated DNA transfection technique, the low metastatic nasopharyngeal cancer cells 6-10B were transfected in vitro with plasmid which contained CD44 gene, and then new nasopharyngeal cancer cells were obtained. The CD44 and EMT-associated proteins in 6-10B, empty vector transfected and CD44-transfected cells were assayed by Western blotting. The erasion trace test was performed to observe the alteration of migratory ability of nasopharyngeal cancer cells before and after CD44 transfection. RESULT: The expression of CD44 and EMT-associated protein MMP-9 in 5-8F was higher than that in 6-10B, but EMT-associated protein E-Cadherin in 5-8F was lower than that in 6-10B. The migratory ability of 5-8F was higher than that of 6-10B. The expression of CD44 and MMP-9 were significantly higher in the CD44-transfected nasopharyngeal cancer cells than in the control groups. Compared with control groups, the migratory ability of CD44-transfected nasopharyngeal cancer cells was significantly increased. CONCLUSION CD44 positively regulates the metastatic ability of nasopharyngeal cancer cells, which is relevant to the process of EMT.

Objective To investigate the risk factors for reduced renal function in patients with ischemic stroke.Methods The medical records of patients with ischemic stroke were analyzed retrospectively.They were divided into normal renal function group and reduced renalfunction group.Reduced renal function was defined as estimated glomerular filtration rate (eGFR) ＜60 ml/(min·1.73 m2).Multivariate logistic regression analysis was used to identify the risk factors for reduced renal function in patients with ischemic stroke.Results A total of 805 patients with ischemic stroke were enrolled in the study.8.8％ of patients had a reduced renal function.There was no significant differences in the proportion of patients with mild and moderate neurological deficit between the reduced renal function group and the normal renal function group (all P ＞ 0.05),however,the proportion of patients with severe neurological deficit was significantly higher than that in the normal renal function group (8.4％vs.2.6％,x2 =5.573,P =0.017).The proportion of small artery occlusion in the reduced renal function group was sigaificantly higher than that in the normal renal function group (66.2％ vs.46.5％,x2 =9.962,P =0.002),and the proportion of large artery atherosclerosis was significantly lower than that in the normal renal function group (19.7％ vs.43.5％,x2 =15.045,P =0.000).Multivariate logistic regression analysis indicated that old age (odds ratio [ OR] 3.301,95％ confidence interval [ CI],1.575 to 6.918; P=0.002) was the most important independent risk factor for reduced renal function,then was female (OR,2.291,95％ CI 1.355to 3.872; P=0.002) and hyperlipidemia (OR,2.527,95％ CI 1.095 to 5.831; P=0.030).Conclusions Reduced renal function in patients with ischemic stroke is strongly associated with old age,female,and hyperlipidemia.

OBJECTIVE: To investigate the efficacy and risk of midazolam and propofol for sedation during colonoscopy procedures in adults of different age groups. METHODS: A total of 180 patients undergoing colonoscopy were allocated to 3 groups: a young adult group (n=45, 18-44 years), a mid-aged group (n=78,45-64 years) and an elderly group (n=57, 65-80 years). All patients were premedicated with midazolam 0.02-0.03 mg/kg and propofol 0.5-2.5 mg/kg. The pulse rate, arterial pressure, and oxygen saturation for each patient were monitored continuously before, during and after the procedure. RESULTS: The doses of midazolam and propofol for the young adults were significantly higher than that for the mid-aged and the elderly (P<0.01). Based on the view of gastroenterologists, the satisfied rate of sedation quality was significantly higher in the elderly group than that in the young or the mid-aged group (P<0.01). There were significant changes in the arterial pressure in all groups compared with the baseline level (P<0.01), but there was no significant difference among the 3 groups. Other parameters such as heart rate, saturation of O2, and the rate of severe adverse reaction among the 3 groups were not significantly different (P>0.05). CONCLUSION Higher dose of midazolam and propofol is needed to obtain the sedation quality in young adults. Whereas for the elderly, properly reducing the dose of midazolam and propofol may still keep the sedation quality during colonoscopy procedures.
