ObjectiveTo investigate the population with an advantage of clinical cure previously treated with nucleos(t)ide analogues (NAs), and to provide more methods for clinicians in pursuing the clinical cure of hepatitis B. MethodsA total of 42 chronic hepatitis B patients with low-level HBsAg who received NAs treatment in Hebi Third People’s Hospital from October 2017 to October 2019 were enrolled as subjects and divided into combination treatment group (group A) and NA monotherapy group (group B). The 22 subjects in group A were treated with NAs combined with PEG-IFN antiviral therapy for 48 weeks, and some patients withdrew from PEG-IFN after 24 weeks and continued to receive NA monotherapy, while the 20 subjects in group B received NA antiviral therapy alone. Both groups were observed till week 48, and the five makers for hepatitis B were measured to evaluate clinical outcome. The t-test was used for comparison of continuous data between two groups, and the Fisher’s exact test was used for comparison of categorical data between two groups; a multivariate logistic regression analysis was used to perform a multivariate analysis. ResultsCompared with group B at the 48-week treatment endpoint, group A had significantly higher HBsAg clearance rate (45.5% vs 0, P＜0.01) and HBsAg seroconversion rate (31.8% vs 0, P＜0.01). The population with HBsAg ＜1000 IU/ml, ＜500 IU/ml, ＜100 IU/ml, and ＜10 IU/ml had an HBsAg clearance rate of 52.6%, 61.5%, 66.7%, and 100%, respectively, and the population with an HBsAg level of 500-1000 IU/ml, 100-500 IU/ml, 10-100 IU/ml, and ＜10 IU/ml had an HBsAg clearance rate of 33.3%, 50%, 40%, and 100%, respectively. The 4 patients with baseline HBsAg ＜10 IU/ml (accounting for 18.2% in group A) achieved clinical cure at week 12 of combined treatment, and after observation to week 48, 2 patients had an anti-HBs level of ＞100 IU/ml and 2 had an anti-HBs level of ＞1000 IU/ml. The multivariate logistic regression analysis of HBsAg clearance showed that age at the initiation of combined treatment affected HBsAg clearance (odds ratio ［OR］=0.877, 95% confidence interval ［CI］: 0.781-0.985, P=0.026), and most of the patients with HBsAg clearance had an age of 36-49 (44.20±4.49) years; baseline HBsAg level also had an impact on HBsAg clearance (OR=0.996, 95% CI: 0.992-1.000, P=0.050). ConclusionThe addition of interferon therapy in chronic hepatitis B patients with low-level HBsAg previously treated with NAs can significantly improve the clinical cure rate. The younger the age and the lower the HBsAg level, the shorter the duration of combined treatment. Age and baseline HBsAg level are more important than the duration and type of NA medication.

Objective To analyze the influence factors ofpathogenesis,clinical manifestations,microscopic morphology and histopathology in children with colonic polyps.Methods 193 cases of colonic polyps were collected in the children's hospital of Soochow University during the period of July 2010 to July 2015.According to the length of the course,all cases were divided into two groups:short-term group (6 months or less),long-term group (＞ 6 months).Results There were 131 boys and 62 girls.The average age was 4.61+2.16 years old.The average disease duration was 7.29±8.30 months (one week to 4 years).There was no significant difference between the two groups in the rate of underweight and anemia,the level of hemoglobin,serum albumin and pre-albumin (P ＞0.05);The main clinical manifestation included hematochezia (98.7％),abdominal pain (17.10％) and protruding tumor (13.47％);The colonoscopy found 197 polyps,in which 189 were single polyp (95.94％),and 8 were multiple polyps (4.06％).Nine polyps (4.57％) were in the right colon,and 188 polyps (95.43％) in the left colon.All of the polyps were divided into 3 groups:huge polyps group (＞ 1.5 cm),large polyps group (0.5～1.5 cm),and small polyps group (＜ 0.5 cm).There were 17 cases found with small polyps (8.63％),119 cases with large polyps (60.40％),and 61 cases with huge polyps (30.96％).Between the three groups,there was no significant difference in age,gender,and duration of the disease (P ＞ 0.05).Histopathologic examination showed that most polyps were juvenile polyps (98.69％),inflammatory polyp account for 1.31％.No adenomatous polyps and malignant polyps were found.Conclusions Hematochezia,abdominal pain and anal tumor are the main complains of colonic polyps in children,there was no significant difference in age and gender.The colonic polyps only have few effects on nutritional status,growth and development in children.Constipation and atopic constitution may be important factors in the development of colonic polyps.The size of colonic polyps has no close relationship with the age,gender and duration of the disease.

Objective To study the application effect of discharge planning combined with continuous nursing in patients with chronic obstructive pulmonary disease (COPD).Methods From May 2014 to April 2015,92 cases of COPD patients in our hospital were selected as the research object,and they were divided into the observation group and the control group according to random number table,with 46 cases in each group. Patients in the control group received continuous nursing,while patients in the observation group were given discharge planning guidance on the basis of continuous nursing. The level of self-efficacy,anxiety, depression,and the treatment compliance of patients before and after intervention were compared between two groups.Results After intervention,the self-efficacy scores of safe behavior,environment and temperature, physical activity,emotional fluctuations,and dyspnea management in the observation group [(3.45±0.15), (2.96±0.24),(2.92±0.26),(2.97±0.24),(2.91±0.23)] were significantly higher than those in the control group [(3.15±0.17),(2.72±0.17),(2.81±0.18),(2.76±0.17),(2.83±0.14)] (P<0.05). The scores of self-rating depression scale (SDS) and self-rating anxiety scale (SAS) in the observation group were significantly lower than the control group [(21.45±2.02),(31.21±3.45) VS (35.43±2.54),(44.46±4.21)] (P<0.05). The treatment compliance in the observation group was significantly better than that in the control group (P<0.05). Conclusions For patients with COPD,discharge planning combined with continuous nursing can obviously improve patient's level of self-efficacy,anxiety,depression,and improve patients' treatment compliance to a certain extent. The effect is good with strong feasibility.

The aim of this study is to investigate the effects of electrical stimulation ES) on the induction of rat bone marrow mesenchymal stem cells (rBMSCs) to differentiate into cardiomyocyte-like cells in vitro. The third or fourth-generation of the rBMSCs was randomly divided into three groups, i. e. ES group, 5-Azacytidine (5-Aza) group, and control group. Those in the ES group with complete medium were exposed to 1,2,4 and 6V, 2Hz, 5ms ES for 2h everyday,lasting for 10d. Those in the 5-Aza group were induced by 10 micromol/L 5-Aza for 24h, then the medium was changed to complete medium without 5-Aza. Those in the control group were only cultured with complete medium. The growth status and morphological features of rBMSCs were observed by inverted phase microscope. The mRNA expressions of GATA4, a-actin, ACTN2 and TNNT2 were determined by Real-time fluorescent quantification PCR, and the protein expression of TNNT2 was detected with immunofluorescence staining. The results showed that the mRNA expression level of the GATA4, a-actin, ACTN2 and TNNT2 and the protein expression level of the TNNT2 were significantly higher in the ES group and 5-Aza group, compared to those in the control group(P<0. 05). It suggested that ES could induce rBMSCs differentiation into cardiomyocyte-like cells in vitro.
