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 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 We aimed to study the distribution of traditional Chinese medicine(TCM)constitution and related influencing factors in patients with impaired glucose tolerance(IGT).Methods A cross-sectional study method was used to enroll IGT patients who attended one of eight collaborating units across China between January and August 2021.Basic information was recorded,physical and laboratory examinations were completed,and the data on TCM constitution were collected according to the"classification and determination table of TCM constitution."Finally,patient information was entered into an Excel table,and the data were analyzed using SPSS 26.0.Results Among the 450 patients,a balanced constitution accounted for 37.3%,yang-deficiency constitution for 15.6%,phlegm-dampness constitution for 14.4%,and dampness-heat constitution for 10.9%.Among the biased constitutions,the proportion of men with dampness-heat constitution was higher than that of women,and the proportion of women with yang-deficiency constitution and blood stasis constitution was significantly higher than that of men(P<0.05).The triglyceride level of patients with phlegm-dampness constitution was higher than that of patients with yang-deficiency constitution(P<0.05);the HDL-cholestrol level of patients with yang-deficiency constitution was higher than that of patients with phlegm-dampness constitution(P<0.05);and the uric acid level of patients with phlegm-dampness constitution,dampness-heat constitution,or yin-deficiency constitution was higher than that of patients with yang-deficiency constitution,and the UA level was the highest in patients with dampness-heat constitution(P<0.05).Conclusion The distribution of TCM constitution in IGT patients was dominated by balanced constitution,followed by yang-deficiency constitution,phlegm-dampness constitution,and dampness-heat constitution.Gender,blood lipid levels,and UA levels were the main factors affecting the constitution status of IGT patients.

Objective:To explore the changes in the functional connectivity (FC) of hippocampal subregions in nicotine addicts after repetitive transcranial magnetic stimulation (rTMS) using resting-state FC.Methods:This study was a cross-sectional study. The clinical and imaging data from 20 male nicotine addicts at Zhejiang Hospital between 2022 and 2024 were analyzed prospectively. All participants received rTMS treatment and were assessed with nicotine-related clinical scales and resting-state FC analysis before and after treatment. The clinical scale evaluations included the Fagerstr?m test for nicotine dependence (FTND), smoking severity index, Minnesota nicotine withdrawal scale (MNWS), short tobacco craving questionnaire (sTCQ), and visual analog scale (VAS). Paired t-tests and Wilcoxon signed-rank tests were used to compare the differences in clinical scale scores before and after treatment. Ten subregions of the bilateral hippocampus (including the hippocampus, dentate gyrus, entorhinal cortex, hippocampus-amygdala transition area, and subiculum) were used as seed points, and paired t-tests were conducted to compare the FC differences in these subregions before and after treatment. Pearson and Spearman correlation analyses were used to assess the correlation between changes in resting-state FC in the rTMS group and clinical scale scores. Results:Compared to pre-treatment, the scores on the FTND, smoking severity index, MNWS, sTCQ, and VAS all significantly decreased after rTMS treatment in nicotine addicts (all P<0.05). Compared to pre-treatment, post-treatment FC was reduced between the left dentate gyrus subregion and the bilateral supplementary motor area and left middle cingulate gyrus, while it increased between the left entorhinal cortex subregion and the right middle and superior temporal gyri, and between the left hippocampus-amygdala transition area subregion and the bilateral calcarine cortex and cuneus (Gaussian random field correction, voxel-level P<0.01, cluster-level P<0.05). Negative correlations were observed between the FC difference in the left hippocampus-amygdala transition area subregion and the right calcarine cortex and the difference in sTCQ-impulse score before and after treatment ( r=-0.447, P=0.048). Negative correlations were observed between the FC difference in the left hippocampus-amygdala transition area subregion and the right cuneus and the difference in the sTCQ-expectation score ( r=-0.559, P=0.010). Negative correlations were observed between the FC difference in the left hippocampus-amygdala transition area subregion and the left calcarine cortex and the differences in sTCQ-emotion and sTCQ-expectation scores ( r=-0.516, P=0.020; r=-0.466, P=0.038, respectively). Negative correlations were observed between the FC difference in the left hippocampus-amygdala transition area subregion and the left cuneus and the differences in sTCQ-emotion and sTCQ-expectation scores ( r=-0.459, P=0.042; r=-0.501, P=0.024, respectively). Conclusion:Changes in FC in certain hippocampal regions are observed in nicotine addicts following rTMS treatment, suggesting that hippocampal subregions may serve as potential biomarkers for nicotine addiction withdrawal to some extent.

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.
