Objective To investigate the curative effect of Teprenone combined with esomeprazole for reflux esophagitis. Methods 96 cases of reflux esophagitis comfirmed by endoscope were obtained and divied into observation group and control group randomly. Both groups were offered with esomeprazole and motilium. Teprenone was added to the observation group and sucralfate was added to the control group. Clinical effective rate,healing rate,adverse reactions and one-year follow up were observed closely after the course of 8 weeks. Results The relief time of clinical symptom and total effective rate in the observation group were(9.3 ±3.5)d and 95.8% respectively,which were significantly higher than those in the control group(P ＜0.05). Endoscopic effective rate was 93.8% in observation group and 81.2% in control group respectively and statistically significant difference was observed (P ＜0. 05). Recurrence rate after one year in the observation group was 8. 3% ,which was significantly lower than in the control group (P ＜ 0.05). One case of headache and nausea occurred in both groups but no severe adverse reaction was observed. Conclusion Teprenone combined with esomeprazole were more effective and more likely to approach the complete cure for reflux esophagitis.

Objective To investigate the methods how to improve condition of procreative health of childbearing disabled women for planned parenthood and good procreation and good education.Methods The method of whole flock sampling of many stages and many layers were taken and the questionnaire and group interview were performed to collect the data of quantity and analyze the affect factors of disabled women about their marriage,procreation,procreative health,and knowledge about procreative health.Results There were 4 380 cases of validity questionnaire.62.33% of them married.In 3 005 procreated women,45.49% had one baby,45.49% had two babies and 8.95% had three babies or more.46.54% of them denied that they had infection of reproductive system.63.19% of them had been examined in department of gynecology.63.17% of them took birth control measure.29.70% of them were lost in taking birth control measure.50.24% of them could say three methods of birth control.37.39% of them could say three ways about AIDS infection.Conclusion Childbearing disabled women have some troubles in birth control,procreative health,and their knowledge about procreative health.

Objective:To investigate the expression of heat shock protein 90 (HSP90) and the relationship between the expression of HSP90 and the clinicopathological features or prognosis in patients with lung adenocarcinoma (ADC).Methods:The paraffin specimens of 193 patients with lung adenocarcinoma and 53 non cancerous lung tissues (bullae and bronchiectasis) resected in Xiangya Second Hospital of Central South University were analyzed retrospectively. The expression of HSP90 in the tissue chip was detected by immunohistochemical streptavidin-perosidase (SP) method by high-throughput tissue chip, and the relationship between its expression level and the clinicopathological characteristics of patients was analyzed; Kaplan Meier survival curve was used to analyze the difference between different expression levels of HSP90 and the overall survival time of patients with lung adenocarcinoma.Results:The positive expression of HSP90 in lung adenocarcinoma was significantly higher than that in non cancerous lung tissue ( P<0.001), the expression level of HSP90 in clinical stage Ⅲ patients was higher than that in clinical stage Ⅰ-Ⅱ patients ( P=0.008), and the expression level of HSP90 in patients with lymph node metastasis was higher than that in patients without lymph node metastasis ( P=0.024); The 10-year survival rate of lung adenocarcinoma patients with high expression of HSP90 was significantly lower than that of patients with low expression of HSP90 ( P=0.001). The 10-year survival rate of lung ADC patients with stage Ⅲ and lymph node metastasis was significantly lower than that of patients with stage Ⅰ-Ⅱ and no lymph node metastasis ( P<0.05). Multiple Cox proportional hazard regression analysis further identified that lung ADC patients with overexpression of HSP90 had a poor prognosis ( P=0.010). Conclusions:HSP90 might play an important part in the development and progression of lung ADC and might act as a novel prognostic marker for patients with lung ADC.

Objective To investigate the mechanism of action of Xiaochaihu decoction in the treatment of hepatitis B based on network pharmacology. Methods The TCMSP database was used to obtain the main chemical components and action targets of the seven traditional Chinese medicines in Xiaochaihu decoction; the GeneCards and OMIM databases were used to obtain the targets associated with hepatitis B; the STRING online platform was used to construct a PPI network of potential targets, and R language was used to perform gene ontology (GO) functional enrichment analysis and KEGG pathway analysis; Cytoscape 3.7.2 was used to construct an "active component-core target" network and perform a topology analysis of this network; AutoDock vina and related software were used to perform molecular docking and visualized analysis of the active components with high value and the core targets in the network. Results A total of 193 main chemical components (including quercetin, kaempferol, wogonin, and naringenin) and 247 related targets were screened out, among which the key targets included RELA, MAPK1, TP53, ESR1, EGFR, and AKT1. A total of 2612 enrichment items were obtained by GO functional enrichment analysis, which were mainly involved in regulating the biological processes such as cell response to chemical stress, response to drugs, oxidative stress response, and lipopolysaccharide response. A total of 174 pathways were obtained by the KEGG pathway analysis, mainly involving hepatitis B, PI3K-AKT signaling pathway, and MAPK signaling pathway. Molecular docking results showed that the main active components had strong binding force to core targets, and the protein crystal complex had a stable conformation. Conclusion This study preliminarily shows that Xiaochaihu decoction exerts a therapeutic effect on hepatitis B through multiple components, targets, and pathways.

Zn²⁺ is required for the activity of many mitochondrial proteins, which regulate mitochondrial dynamics, apoptosis and mitophagy. However, it is not understood how the proper mitochondrial Zn²⁺ level is achieved to maintain mitochondrial homeostasis. Using Caenorhabditis elegans, we reveal here that a pair of mitochondrion-localized transporters controls the mitochondrial level of Zn²⁺. We demonstrate that SLC-30A9/ZnT9 is a mitochondrial Zn²⁺ exporter. Loss of SLC-30A9 leads to mitochondrial Zn²⁺ accumulation, which damages mitochondria, impairs animal development and shortens the life span. We further identify SLC-25A25/SCaMC-2 as an important regulator of mitochondrial Zn²⁺ import. Loss of SLC-25A25 suppresses the abnormal mitochondrial Zn²⁺ accumulation and defective mitochondrial structure and functions caused by loss of SLC-30A9. Moreover, we reveal that the endoplasmic reticulum contains the Zn²⁺ pool from which mitochondrial Zn²⁺ is imported. These findings establish the molecular basis for controlling the correct mitochondrial Zn²⁺ levels for normal mitochondrial structure and functions.
