As a wide field of internet industry, the internet medical is sprouting prosperous with many advanta-ges still, namely promoting the medical resources integration and earlier disease prevention, providing more conven-ient health care services, etc. , but there are still many limitations. By analyzing the role of internet in the promotion of medical services, this article focused on the internet limitations. Ultimately, we put forward we should calmly oper-ate internet and make it as the auxiliary tool for medical care services instead of relying too much on it in order to pro-vide a reference and a basis for the prosperous development of internet medical.

Medical insurance system plays a key role in China's social security system.In the social insurance system,medical insurance features the widest coverage and the most complex in mechanism,while China' s medical insurance system itself is found with many setbacks.This paper probed into such risks found in the county-level medical insurance system as excessive cost growth causing overpayment of the medical insurance fund and poor supervision of the fund.On such basis,the authors recommended such policy changes as payment reform,and enhanced supervision over the fund,the demand side,and the government,in an effort to optimize China' s medical insurance system for theoretical and decision reference of other county-level hospitals in their reforms.

Objective To analyze the assets and liabilities of secondary public hospitals of Wuhan city in Hubei province ,in order to provide references to control the debt scale of such hospitals .Methods Twenty‐one public secondary public hospitals of Wuhan city were analyzed using official statistics on their asset and liabilities from 2012-2014 .Results Such a timeframe witnessed a year‐on‐year growth of both total assets and liabilities of these hospitals ,yet the growth rate of total assets(35.15% ) falls behind that of total liabilities (53.62% )significantly ;significantly slower growth rate of non‐current assets since 2013 ;higher current liabilities than long‐term liabilities on yearly basis ;year‐on‐year grow th of liquidity rate and quick ratio in general ;significant rise of debt‐to‐assets ratio .Conclusions The overall debt scale of such hospitals keeps growing ,a trend deserving actions and correction .

As an important part of the hierarchical medical system in China ,urban secondary hospitals play as a pivot between tertiary hospitals and community healthcare centers.By describing the overall development status of such hospitals in China ,the paper discussed the problems existing in the development of urban secondary hospitals and put forward strategies in the hope of providing reference for the transformation of these hospitals .

Objective To investigate the effects of specific methyltransferase inhibitor of 5-Aza-2'-deoxycytidine (5-Aza-CdR) on the promoter methylation of E-cadherin (E-cad) gene, protein expression in human cervical cancer SiHa cells, and the cell biological behavior. Methods SiHa cells were treated with 5-Aza-CdR at different concentrations. Quantitative methylation-specific polymerase chain reaction (QMSP) was used to examine CpG island promoter methylation level of E-cad gene before and after treatment. The experimental group of the optimum concentration was selected. The expression levels of E-cad mRNA and its protein in SiHa cells line were detected by quantitative real-time polymerase chain reaction (RT-PCR) and western blot respectively. Cell adhesion test was used to measure cell adhesion ability and Transwell test was used to detect cell invasion and migration ability. Results E-cad gene promoter methylation index (PMR) of 5-Aza-CdR at 0, 1, 5, 10, 15 μmol/L level was (53.0 ±1.6) %, (50.0 ±1.2) %, (44.0 ±1.4) %, (27.0 ±1.7) %, (15.0±8.2) %respectively, and PMR value decreased gradually with the increase of 5-Aza-CdR concentration. Furthermore, PMR value was the lowest at 15μmol/L, and the difference was statistically significant compared with other 4 groups (P< 0.01). Then 5-Aza-CdR at 15 μmol/L was selected as the following experimental concentration. The expression of E-cad mRNA and its protein in the 5-Aza-CdR group were significantly higher than those in the blank control group (P<0.05). The rates of cell adhesion , cell invasion inhibition and migration inhibition were all increased with significant differences (P<0.05). Conclusions 5-Aza-CdR can upregulate E-cad mRNA and protein expression level in cervical cancer SiHa cells, reduce cell invasion and migration ability, and promote the adhesion of SiHa cells, which has reversed hypermethylation in the promoter region of E-cad gene partly.

Objective To evaluate the clinical effect of dextromethorphan and its effect on daily living of patients with poststroke pseudobulbar affect. Methods Sixty patients with poststroke pseudobulbar affect admitted in our hospital from May 2013 to October 2016 were enrolled. Then they were randomly divided into the control group and the treatment group,with 30 patients in each group.Patients in the control group were treated with fluox-etine therapy and patients in the treatment group were treated with dextromethorphan therapy.The center for neuro-logic study lability scale(CNS-LS)and activity of daily living(Barthel index,BI)before and 30 days after the treat-ments in the two groups had been accessed. Results Thirty days after the treatment,CNS-LS of the treatment group had obvious improvement compared with that before treatment(P < 0.01),but CNS-LS of the control group had no obvious improvement compared with that before treatment(P > 0.05). And significant improvement has been found 30 days after the treatment between the two groups(P<0.01).Furthermore,significant difference was found on BI between these two groups(P<0.05).Conclusions Dextromethorphan is effective in treatment of pa-tients with poststroke pseudobulbar affect and it can improve the activity of daily living of these patients.

BACKGROUND: The mortality of lung cancer ranks first among all malignant tumors, but there are few studies on the effect of different segmentectomy on lung function in patients with early lung adenocarcinoma. The purpose of this study was to evaluate the degree of lung function preservation and short-term results of preoperative planning combined with fluorescence thoracoscopic precision segmentectomy and traditional segmentectomy in patients with early lung adenocarcinoma. METHODS: From January 1, 2020 to October 31, 2020, 60 patients underwent thoracoscopic segmentectomy in the Department of Thoracic Surgery of the First Affiliated Hospital of University of Science and Technology of China: 30 patients in precision segmentectomy group and 30 patients in traditional segmentectomy group. The clinicopathological features, perioperative data and postoperative pulmonary function of the two groups were compared. RESULTS: The operation time of the precision group was shorter than that of the traditional group, and the difference was statistically significant (P<0.05). The preoperative pulmonary function accuracy group and the traditional group in forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and carbon monoxide diffusing capacity (DLCO) were (3.65±0.63) L vs (3.54±0.64) L, (2.72±0.50) L vs (2.54±0.48) L and (20.36±3.02) mL/mmHg/min vs (19.16±3.18) mL/mmHg/min, respectively. One month after operation, the FVC, FEV1 and DLCO of pulmonary function accuracy group and traditional group were (3.35±0.63) L vs (2.89±0.57) L, (2.39±0.54) L vs (2.09±0.48) L and (17.43±3.10) mL/mmHg/min vs (15.78±2.865) mL/mmHg/min, respectively. Three months after operation, the FVC and DLCO of pulmonary function accuracy group and traditional group were (3.47±0.63) L vs (3.20±0.56) L and (19.38±3.02) mL/mmHg/min vs (17.79±3.21) mL/mmHg/min, respectively. CONCLUSIONS Preoperative planning combined with fluorescence thoracoscopic precise segmentectomy provides advantages in intersegmental plane recognition, vascular anatomy and postoperative recovery, which significantly shortens the operation time and makes the treatment more accurate.
