Status of health communication of medical institutions using new media platforms in Shanghai / 上海预防医学

ObjectiveTo investigate the current situation of health communication carried out by medical institutions in Shanghai through new media platforms such as WeChat， Weibo， Toutiao， Douyin， Kuaishou， Bilibili and WeChat Videos， and to propose targeted measures. MethodsBased on the systematic collection of new media accounts of medical institutions in Shanghai， and through the combination of keyword screening and manual audit， health communication data of medical institutions on new media platforms were determined. ResultsData from 1 117 new media accounts of 162 medical institutions in Shanghai were collected， including 610 WeChat official accounts， 105 WeChat video accounts， 89 Weibo accounts， 18 Bilibili accounts， 198 Douyin accounts， 37 Toutiao accounts， and 60 Kuaishou accounts， totaling 111 853 posts. After keyword sorting and manual screening， a total of 66 761 health science posts were collected， with WeChat Official Accounts， Douyin， and Weibo having the top three highest number of posts. Video-based new media such as Douyin， WeChat Videos， Kuaishou， and Bilibili had a better communication impact than text and image-based new media like WeChat Official Accounts， Weibo， and Toutiao. Among them， Douyin and Toutiao were the best platforms for video and text-image-based new media， respectively. ConclusionMedical institutions in Shanghai recognize the importance of new media in health communication and have made full use of various media platforms to carry out health communication，having a certain impact on health education. In the future， medical institutions should choose appropriate platforms based on target audiences and content characteristics， fully leverage the advantages of various platforms， explore innovative communication strategies， promote the dissemination of health knowledge， and enhance the health literacy of the public.

Effect of triple therapy and sequential therapy on eradication of Helicobacter pylori in long-term aspirin use / 中国生化药物杂志

Objective To analysis curative effect of triple therapy and sequential therapy for eradication of Helicobacter pylori in patients with long-term aspirin use.Methods 52 patients with long-term aspirin use who were diagnosed with helicobacter pylori infection were collected.All patients were divided into sequential group and triple group according to different drugs classified, each 26 cases in each group were given corresponding drug treatment, after the end of treatment, the serum pepsinogen, Hp-IgG antibody levels and Helicobacter pylori clearance rate were detected in all patients. Results After treatment, compared with the triple Group, in the sequential group, the levels of serum PG I and PG II were lower, and PGⅠ/PGⅡwas higher, and the differences were statistically significant (P<0.05);the serum Hp-IgG antibody levels were lower in the sequential group (P<0.05);the Hp clearance rate of patients in the sequential group was higher (P<0.05).Conclusion Compared with triple therapy, sequential therapy can lower serum PG, PG II and Hp-IgG levels, and improve the Hp clearance rate and clinical efficacy, have guiding significance to clinical.

Determination of Plasma 5-HT Concentration and its Clinical Significance in Patients with Sudden Deafness / 医学研究杂志

Objective To explore the relationship between plasma 5-HT and patients with sudden deafness and the pathogenesis in sudden deafness.Methods 46 inpatients with sudden deafness as patient group,and 34 healthy as control group.They were determined the plasma 5-HT concentration by immunoradiometric assay,then statistics analysis,and investigated negative life events in one week before admission.Results There is significant difference in 5-HT concentration between two groups.In patient group,35 cases(76%) had anxiety,depression emotion and sleep disorder before attack.Conclusions The high level of the plasma 5-HT concentration is probably one of the mechanisms in the patients of sudden deafness.Whether there is relationship between plasma 5-HT concentration and the degree and prognosis of sudden deafness needs to be further studied.

Construction of TRAIL eukaryotic expression vector driven by the hTERT promoter and apoptotic effect on nasopharyngeal carcinoma cell line CNE-2 / 中国耳鼻咽喉头颈外科

OBJECTIVE To explore the effect of gene therapy on the nasopharyngeal carcinoma (NPC) cell line CNE-2 by using the combination of TRAIL gene with hTERT promoter. METHODS Total RNA was ex-tracted from PBL (peripheral blood lymphocytes)whose proliferation had been stimulated. TRAIL gene with interleukin 2 signal peptide gene was amplified by RT-PCR and cloned into the vector pGL3-181hTE down-stream to the RT promoter to form an eukaryotic vector. The vector was transfected into CNE-2 cells and HL-7702 cells through lipofection. Flow cytometry (FCM), agarose gel electrophoresis and cell morphology were used to examine the cell apoptosis. RESULTS In tranfected nasopharyngeal carcinoma cells CNE-2, FCM analysis showed that apoptotic peak appeared before G1 phase. A ladder-like pattern of DNA fragmentation appeared upon agarose gel electrophoresis. Many cells exhibited apoptotic changes such as cell shrinkage , nulear condensation , and nuclear fragmenta-tion under transmission electron microscope (TEM). CONCLUSION The recombinant eukaryotic ex-pression vector for TRAIL gene driven by hTERT pro-moter was successfully constructed and shown to induced apoptosis in CNE-2 cells. The results suggest that TRAIL may be a promising target for gene therapy of NPC.
