ObjectiveTo investigate the clinical efficacy of pricking-medicinal cupping bloodletting therapy for knee osteoarthritis.MethodSixty patients with knee osteoarthritis were randomly allocated to pricking-cupping bloodletting (treatment) and conventional treatment (control) groups, 30 cases each. In the treatment group, specific points around the knee were pricked with bloodletting needles and blood was removed by cupping with decoction. In the control group, the same points were given acupuncture and the affected part was given microwave treatment. The WOMAC score was recorded in the two groups of patients before treatment and after the end of treatment course. The therapeutic effect was evaluated by comparing the pre-and post-treatment scores between the two groups.ResultThere was a statistically significant pre-/post-treatment difference in the WOMAC total score in the two groups (P<0.01). The range of decrease in the WOMAC total score was significantly larger in the treatment group than in the control group. There was a statistically significant post-treatment difference in the WOMAC total score between the two groups (P<0.01). The WOMAC item scores decreased in varying degrees in both groups after treatment (P<0.01). The total efficacy rate was statistically higher in the treatment group than in the control group; there was a statistically significantdifference (P<0.05). The clinical therapeutic effect was statistically better in the treatment group than in the control group.Conclusion Pricking-medicinal cupping bloodletting is statistically better than conventional treatment in treating knee osteoarthritis. It can effectively relieve the pain and stiffness and improve knee function and the quality of life in the patients.

Objective To investigate the effect of resveratrol on miRNA-106b in Alzheimer′s disease ( AD ) animal model.Methods Fifty Kunming male mice were divided into five groups by completely randomized block sampling.The five groups included three dosage resveratrol groups , an AD model group and a control group.The AD models were established in one month prior to treatments. Subsequently, from the 31st day various doses of resveratrol were provided intragastricly for 60 days.Then the memory function was observed by the step-down test.Meanwhile, the varying expressions of APP , P62, ApoA1, miRNA-106b, ABCA1 were tested in each group to determine whether there is the binding site for miRNA-106b in APP 3′UTR sequence.Results Compared with the control group by step-down test, the memory function of the AD model group mice decreased in different degree , which in the drug treatment group was higher than that in the model group (P<0.05).Compared with the AD group, the expression of APP (1.131 ±0.035) in the drug treatment group was higher than that in the model group (0.652 ± 0.026), while the P62 (0.412 ±0.022) and ApoA1 (0.534 ±0.032) were lower than the model group ( all P<0.05 ).High and medium dose groups of resveratrol treatment reduced varying degrees of APP (0.733 ±0.018,0.929 ±0.019,F=177.733) levels, and increased P62(0.954 ±0.035,0.633 ±0.015, F=434.5 ) and ApoA1 ( 1.042 ±0.051, 0.824 ±0.034, F=286.582 ) levels ( all P<0.05 ).The expression of miRNA-106b (0.464 ±0.313) and ABCA1(0.293 ±0.042) in the model group was lower than that in the control group (miRNA-106b 1.064 ±0.032, F=238.159; ABCA1 0.781 ±0.027,F=341.61;both P<0.05).The miRNA-106b (0.843 ±0.034, 0.601 ±0.012) and ABCA1 (0.882 ± 0.025, 0.624 ±0.036) levels in the high, medium dose resveratrol treatment groups increased to different extent ( both P<0.05 ).After the drug treatment , luciferase reporter vector experiments showed that the APP 3′UTR sequence contains the binding site of miRNA-106b.Conclusions APP is one of the target genes of miRNA-106b.Resveratrol is capable of improving AD by enhancing the expression of miRNA-106b and down-regulating the target genes including APP , P62 and ApoA1.This provides a new theoretical basis for the clinical treatment of AD.

Objective To investigate the relationship between acute cerebral infarction(CI)and matrix metalloproteinase-9(MMP-9)serum level and polymorphism(C-1562T)in Han population.Methods One hundred and one patients with acute CI from the department of neurology of Taizhou Hospital were included and 114 healthy persons were selected from physical examination as the control group.Serum MMP-9 level was measured by enzyme-linked immunosorbent assay(ELISA).At the same time.genotype was determined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)for the common C-1562T functional promoter polymorphism of the MMP-9 gene.The serum MMP-9 level and genotype frequencies of the MMP-9 gene between the patients and the control group were analyzed.Results The genotype frequencies of the MMP-9 gene C-1562T polymorphism of the two groups were in Hardy-Weinberg equilibrium.The results of individual polymorphisms analysis showed that the frequencies of CT and TT genotypes in the C-1562T polyporphismin were of no significant difference between the patients group with CI(13.9%)and the control group(13.2%).The frequencies of-1562T allele was of no statistical difference between the CI group(6.9%)and the control group(7.5%).But serum levels of MMP-9 in CI patients group((138.9±121.8)ng/ml)were significantly higher than in the control group((18.4±4.6)ng/ml,t=9.93,P=0.00).Conclusions Serum level of MMP-9 obviously is increased after ischemic stroke in 48 hours.But genetic polymorphism in MMP-9 promoter(C-1562T)has no definite relationship with MMP-9 genetic expression and CI in the Han population of China.Therefore,the relationship between genetic polymorphism in MMP-9 promoter(C-1562T)and ischemic stroke needs further investigation.

Objective:To investigate the effect ofLeech Capsule on stability ofcarotid plaque and expression ofplatelet membrane glycoprotein in patients with cerebral arteriosclerosis.Methods:203 patients with cerebral arteriosclerosis which with unstable carotid plaque were divided into two groups.There were 101 patients in observation group which were treated by conventional therapy and Leech Capsule, and 102 patients in control group which were treated only by conventional therapy.Then comparison analysis ofIMT, plaque area, unstable plaque number and positive rates ofPAC-1 and CD62P were made before and after treatment with two groups.Results:After treatment, the IMT, plaque area, unstable plaque number and positive rates ofPAC-1 and CD62P in observation group were significantly lesser than those in control group.In observation group, all parameters after treatment were significantly lesser than those before treatment, but in control group there were no significant difference in IMT and positive rates ofCD62P between after treatment and before treatment.In addition, there were no obvious adverse reactions after treatment by leech capsule.Conclusion:Leech Capsule was an effective drug for stabilizing carotid plaque and depressing the level ofplatelet activation, and it had few adverse reaction.It was worth further spreading.

Objective To investigate the association of serum levels of matrix metalloproteinase-12 (MMP-12) and a functional polymorphism in the promoter - 82A/G of the MMP-12 gene with acute atherosclerotic cerebral infarction (ACI).Methods All 608 cascs of acute ACI and 374 healthy controls were included in the study.Serum levels of MMP-12 were measured using the enzyme-linked immunosorbent assay (ELISA). At the same time,polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was performed on the - 82A/G polymorphism in the MMP-12 gene.Results The serum levels of MMP-12 in ACI group (( 17.36 ± 9.12) ng/ml) were not significantly higher than those in the healthy control group ( ( 17.42 ± 7.70) ng/ml,t ＝ 0.047,P =0.962).The frequency of the AG + GG genotypes was not significantly different between the two groups (7.6％ vs 5.9％,x2 =0.281,P =0.584),and the frequencies of the G allele were 3.8％ and 2.9％ in the ACI group and the control group respectively which were also not significantly different between the two groups ( x2 =0.746,P =0.374).Conclusion There is no correlation between serum level with genetic polymorphism in MMP-12 promoter (-82A/G) and cerebral infarction.

A "general-special integrated" prevention and treatment model for chronic obstructive pulmonary disease (COPD) patients in the community was preliminarily established with the joint effets of specialists from the terital hospital and general practitioners in the community health service center.During the implementation of the model the general practitioners recieved research training and participanted in the research project of COPD management;and the "general-special integrated" outpatient clinic greatly improved the management for COPD patients.Since the establishment of the model,the number of acute attacks of COPD patients was decreased,and the proportion of standardized medication was increased.The model also improved the research ability and clinical competency of general practitioners.The established model provides experiences for the tiered-management for COPD patients in the community.

OBJECTIVES: To analyze the clinical characteristics in patients of coronavirus disease 2019 (COVID-19) complicated with liver injury, to explore the relationship between COVID-19 clinical classification and liver injury, and to elucidate whether COVID-19 complicated with hepatitis B virus can aggravate liver injury. METHODS: The abnormal liver function in 110 patients in the First Hospital of Changsha, who were confirmed COVID-19 and admitted to the designated hospital from January 17, 2020 to February 20, 2020, wereretrospectively analyzed. The detection indexes included serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBIL). RESULTS: A total of 49.1% of the COVID-19 patients had liver injury. There were significant difference in the ALT, AST, ALB (all <0.05), but there was no significant difference in the TBIL (>0.05) between the severe (critical) patients and the general (light) patients. There was also no significant difference in the liver function injury between the HBsAg-positive COVID-19 patients and HBsAg-negative COVID-19 patients (>0.05). Acute liver injury was not found to be a direct cause of death in the patients. CONCLUSIONS In the COVID-19 patients, the incidence of liver injury is high with the increase of ALT and AST and the decrease of ALB. Severe and critical patients have obvious liver injury, and those patients complicated with hepatitis B virus infection don't show aggravated liver injury.
