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 observe the effect of the 8-word bandage on the walking ability of stroke patients with knee hyperextension. Methods Fifty patients with stroke combined with knee hyperextension were randomly divided into the observation group and the control group with 25 cases in each group. The control group was treated with conventional methods, including Bobath technology, Brunnstrom therapy and motor relearning primarily rehabilitation training. In addition to the conventional methods, patients in the observation group used 8-word bandage to fix knee joint in walking training. Before and after 8 weeks of treatment, Holden walking function classification, 10-meter maximum walking speed and improved Barthel index were adopted to evaluate the walking ability, maximum walking speed and the life ability of the patients. Results There were no significant differences in the scores before treatment between the two groups. The Holden walking function classification, the 10-meter maximum walking speed and the Barthel index scores were significantly improved after 8-week treatment in both two groups (P<0.05), and patient conditions were more significantly improved in the observation group than those of the control group (P<0.05). Conclusion Using 8-word bandage to fix knee joint can significantly improve knee hyperextension in patients with stroke, so as to improve the walking ability and activities of daily living.

Objective To investigate the lipid hepatoprotective effect of silibinin on high fat diet-induced nonalcoholic fatty liver (NAFL) rat model and provide a theoretical basis for the treatment of silibinin on NAFL.Methods The NAFL rat model was established by administration of high fat emulsion and high fat diet.Rats in control group was treated with saline and normal diet.The model rats were randomly divided into model group,simvastatin (positive drug,1.8 mg/kg) group,Silibinin groups with low,middle and high doses (18.9,37.8 and 75.6 mg/kg).From the fifth week,NAFLrats were treated with different drugsonce a day for eight weeks.All rats were anaesthetized after final administration,Livertissues were weighed for the calculation of hepatic coefficient The hepatic morphology was observed through HE staining.Serum was obtained from abdominal aortic blood for detection of triglyceride separation (TG),total cholesterol (TC),high density lipoprotein (HDL),low-density lipoprotein (LDL),aspartate aminotransferase (AST),and alanine aminotransferase (ALT) levels.Results After eight-week treatment,compared with model group,middle and high doses of silibinin could significantly improve the hepatic steatosis.The levels of hepatic coefficient,serum TC,TG,AST and ALT in rats treated with individual dose of Silibinin were significantly decreased (P ＜ 0.05,0.01).Particularly,high dose of silibinin significantly reduced LDL level whereas elevated HDL level in serum (P ＜ 0.01).Conclusion Silibinin has a therapeutic effect on nonalcoholic fatty liver rats,and possible mechanism is related to lipid-lowering and hepatic protection.

OBJECTIVETo analyze the association between T393C single nucleotide polymorphism (SNP) of GNAS1 gene and non-valvular atrial fibrillation (AF) in Chinese Han patients.

METHODSNinety patients with non-valvular AF and 90 healthy subjects were examined for T393C SNP of GNAS1 gene using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The allele genotypes and the distribution of allele frequencies were analyzed and compared between the two groups. The relationship between allele frequency distribution characteristics and the heart rate variability (HRV) were also studied for analysis of the association between T393C SNP of GNAS1 gene and the autonomic nervous activation in non-valvular AF.

RESULTSThe two groups showed a significant difference in the frequencies of genotypes of T393C SNP of GNAS1 gene and allele frequencies (P<0.01). CC genotype and T393C allele frequency were significantly increased in the case group. pNN50, LF, or LF/HF showed no significant difference between different genotypes (P<0.05).

CONCLUTIONSThe T393C SNP of GNAS1 gene is closely associated with non-valvular AF in Chinese Han patients.

Objective: To evaluate the efficacy and safety of compound Lactobacillus acidophilus tablets or Saccharomyces boulardii Sachets combined with standard protocols for eradication of Helicobacter pylori(Hp) in children. Methods: From March 2017 to March 2018, 120 children aged 3-10 years with Hp infection were admitted into the Department of Gastroenterology, Maternal and Child Health Hospital of Hubei Province, including 67 male and 53 female childen.They were divided into 3 groups (control group, compound Lactobacillus acidophilus group, Saccharomyces boulardii Sachets group) by the method of random number table.Control group was given Clarithromycin+ Amoxicillin+ Omeprazole, for 14 days orally; compound Lactobacillus acidophilus group and Saccharomyces boulardii Sachets group were given drugs respectively on the first day, 500 mg of compound Lactobacillus acidophilus was added, twice a day or 250 mg of Saccharomyces boulardii Sachets group, twice a day orally, for 14 days, respectively.The adverse reactions in children were observed during the treatment, andurea ¹³C breath test or the stool Hp antigen test was performed at least 4 weeks by the end of the treatment, and the children with negative results were judged to be eradicated successfully.The ulcer healing, Hp eradication rate and incidence of adverse reactions(nausesa, vomiting, loss of appetite, constipation, diarrhea) among the 3 groups were observed and the Hp eradication rate and the incidence of adverse reactions (nausea, vomiting, loss of appetite, constipation, diarrhea) were compared. Results: The eradication rates in the control group, the compound Lactobacillus group, and Saccharomyces boulardii Sachets group were 80.0% (32/40 cases), 85.0% (34/40 cases), and 87.5% (35/40 cases), respectively, and the difference was not statistically significant (P=0.646); the ulcer healing rate was 100.0% of 101 Hp eradicators in 3 groups, and the ulcer healing rate of 19 cases without Hp eradicated was 48.15%, and there was a significant difference between them (χ²=51.30, P<0.01). However, there was no significant difference in the total effective rate among 3 groups (P>0.05). The overall incidence of adverse reactions in Saccharomyces boulardii Sachets group (P=0.021) and the incidence of diarrhea (P=0.002) and loss of appetite (P=0.021) was lower than that in the control group, and the differences were statistically significant.There was no significant difference in the incidence of adverse reactions between the two probiotic groups (P>0.05). Conclusions Both compound Lactobacillus acidophilus tablets and Saccharomyces boulardii Sachets group can reduce the overall incidence of adverse reactions and the incidence of diarrhea and appetite declines in children′s standard Hp eradication regimen without affecting Hp eradication rate.

Peutz-Jeghers syndrome (PJS) presents in early childhood, and children have a higher risk of intussusception due to a smaller abdominal space than adults. Double-balloon enteroscopy (DBE) has been proven to be a safe and effective method for the diagnosis and treatment of small bowel lesions, but the efficacy and safety of its prophylactic polypectomy in children with PJS need to be determined. Data of 6 children (median age 10.6 years) diagnosed as having PJS from 2018 to 2020 were reviewed. DBE was performed 14 times, and 3 children were successfully relieved of intussusception after DBE treatment. The sizes of the resected intussusception polyps were 50 mm×60 mm, 40 mm×35 mm, and 50 mm×40 mm. Symptoms associated with polyps (abdominal pain, intussusception and obstruction) relieved after DBE in all children. No direct complications such as bleeding or perforation were found during the operation, and no recurrence of intussusception was found during follow-up. It can be seen that DBE polypectomy is safe and effective in the treatment of intussusception caused by PJS.
