Objective: The purpose of this study was to determine the relationship between TCM pattern and Hp infection and apoptosis of stomach mucosa in chronic gastritis, to discover the substance of TCM Pattern of chronic gasuitis on genetic molecular level and to establish syndrome differentiation system of chronic superficial gastritis on molecular level Methods: Get gastric mucosa tissue by electronic gastroscope. Hp infection, expression of Fas and bel-2 of 41 cases of incoordination between the liver and stomach group (IBLS group) and 50 cases of Dampness-beat in spleen and stomach(DHSS group) of chronic superficial gastritis were investigated by immunohistocbemistry examination, with 10 healthy persons as control group. Muti-factor non-condition logistic regression analysis was adopted to analyze the data. Results: The positive rate of HP was of 22%, 52% and 10% respectively in the IBLS group, the DHSS group and the control group. The positive rate of HP in the DHSS group was significant higher than in the IBLS and control group, showing there is a significant correlation between DHSS patern and HP infection. The expression rate of bcl-2 antigen was 24.2%, 76.0% and 30.0% respectively in the IBLS, DHSS and control group. The expression rate of bcl-2 antigen in the DHSS group was significant higher than in and the IBLS and control group(P＜0.01), showing there was significant correlation between DHSS pattern and expression rate of bcl-2 antigen(P＜0.01). The expression rate of Fas antigen was 70.7% and 46% respectively in the IBLS and DHSS group, the expression rate of Fas antigen in the IBLS group was significant higher than in DHSS group(P＜0.01), showing there was a significant correlation between IBLS pattern and expression rate of Fas antigen(P＜0.01).Conclusion: The result suggested that there was a certain relationship between HP infection and TCM pattern, the positive rates of HP was higher in DHSS pattern compared with the IBLS group. There was a certain relationship between the expression of bcl-2 and Fas in DHSS pattern, IBLS pattern may probably promoted apoptosis in gastritis, whereas HP infection performed as a main role in apoptosis in DHSS pattern. Bcl-2, liP and Fas might contribute to syndrome differentiation of chronic gastritis.

Objective To explore more suitable calculation method of the insulin dosage in insulin hypoglycemia-growth hormone stimulation test(insulin tolerance test, ITT). Methods Fifty-six subjects suspected of growth hormone deficiency were divided into primary and secondary onset groups. All the patients took oral glucose tolerance test and ITT. Homeostasis model of assessment for insulin resistance index ( HOMA-IR) and insulin sensitivity index ( ISI), area under insulin curve ( AUCINS ) and the area under glucose curve ( AUCPG ) were calculated. The insulin dosages during ITT between two groups were compared and the main factors influencing the insulin dosage were analyzed. Results There was no difference in the insulin dosage during ITT between primary and secondary groups. The actual dosage of insulin in this cohort study revealed a significant difference from the initial insulin dosage recommended by the guideline. Multiple linear regression analysis found that AUCINS and body mass index were the independent factors affecting the insulin dosage. Then the optimized coefficient of ITT ( γ) were found. Conclusion The insulin dosage used in our study was inconsistent with the guidelines-recommended ones. In order to make ITT more efficient and safer, a more optimized calculation method to improve the successful rate of insulin-induced hypoglycemia in ITT is proposed.

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 Based on Chinese guidelines for the management of ischemic stroke, a standardized stroke management program was performed to provide intensive education and training for medical physicians, aiming to enhance their knowledge and ability for ischemic stroke prevention and treatment, thereby reducing patients′ in-hospital cost and length of stay, and improving patients′ clinical prognosis. Methods This study was conducted in 20 general hospitals throughout Hainan province. A total of 163 physicians from 20 hospitals involved in the management of stroke patients were trained by highly experienced physicians based on the Chinese guidelines for diagnosis and treatment of acute ischemic stroke 2014 and the Chinese guidelines for secondary prevention of ischemic stroke and transient ischemic attack 2014. Prior to and post the standardized stroke management training, the data of 3218 and 3367 patients with ischemic stroke were respectively collected. Quality of life assessments including the Barthel index (BI) and the modified Rankin Scale (mRS) score of all patients were recorded at baseline and after discharge. The length of stay and in-hospital cost were directly collected from the hospital information system. Results Physicians′ knowledge and ability manifested as testing scores were significantly improved after training (78.2 ± 15.5 vs 55.6 ± 10.7, t=69.1, P<0.01). The average length of stay of post-training patients was significantly shorter than that of pre-training patients ((8.7 ± 0.9) vs (11.7 ± 1.5) days, t=97.9, P<0.01). The average in-hospital cost of post-training patients was significantly less than that of pre-training patients ((7681.7 ± 1397.7) vs (11846.2 ± 2514.6) Yuan, t=82.5, P<0.01). Both BI (68.2 ± 3.2 vs 43.5 ± 5.3, t=227.7, P<0.01) and mRS score (2.74±0.51 vs 3.65±0.71, t=59.5, P<0.01) were significantly improved for post-training patients. Multivariate linear regression analysis illustrated that standardized stroke management was negatively associated with in-hospital cost (r=-0.461, P<0.01), length of stay (r=-0.357, P<0.01) and mRS score (r=-0.298, P<0.01), and was positively associated with levels of BI (r=0.376, P<0.01). Conclusion Standardized stroke management program might be a cost-effective choice for the management of ischemic stroke as it reduces the in-hospital cost and improves patients′BI and mRS levels.
