Purpose: To observe the long-term and recent clinical effect of needle-warming method plus functional training in the treatment of osteoarthritis of the knee joint. Methods:After 106 cases of the patients were divided into the needle-warming group and comprehensive group by the order of their first visit, the needle-warming group was treated by the needle-wanning method and the comprehensive group was treated by the needle-warming method plus functional training. After ten treatments, the clinical data in the two groups were evaluated upon Lequesne scale before and after the treatments. Three months later, follow-up survey was given to process the statistic management of the reoccurrence rate of the symptoms.Results: In the two groups after the treatment, the symptoms of the knee joint and daily life ability were obviously improved than the respective conditions before the treatment, and the integral decreased (P＜0.05), with no significant difference (P＞0.05) between the two groups. In the follow-up survey, there was a difference (P＜0.05) between the two groups in the positive rate of the recurrent symptoms. Conclusion: Certain therapeutic effect exists in the treatment of osteoarthritis of the knee joint by the needle-warming method. If functional training is combined,the therapeutic effect would be more stable, without easy reoccurrence.

Objective To investigate the correlation between Toll-like receptor2 (TLR2) gene promoter region -597T/C polymorphism and primary ANCA associated small vasculitis (AAV) in Guangxi Han people. Methods A case contrastive control study was adopted in the study. Patients with AAV (patients group, n=110) and healthy people (control group, n = 200) were recruited. Associated serum indexes were detected and polymorphisms of TLR2 gene promoter 597T/C were analyzed by polymerase chain restricted fragment length polymorphisms (PCR-RFLP). Results (1)Three TLR2-597T/C genotypes were discovered in 110 AAV patients, namely, TT, TC and CC, with the frequency of 54.55%,40.00% and 5.45% respectively. And the frequencies of allele T and C were 74.55% and 25.45%. In control group, the genotype frequencies of TT, TC and CC were 56.00%,40.50% and 3.50%, with 76.25% of allele T and 23.75% of allele C. No significant differences were found in neither genotype distribution nor allele frequencies between the patients group and control group ( P > 0 . 05 ) . ( 2 ) Significant differences were found in the incidence of proteinuria rate and the hemoglobin (P< 0.05)in AAV patients. (3)There was no significant difference between AI and CI in TT, TC and CC genotype in AAV patients. Conclusions Polymorphism of TLR2-597T/C may be correlated with the incidence of proteinuria and the level of hemoglobin, while no obvious correlation with the genetic susceptibility of ANCA in vasculitis patients of Guangxi Han people.

Objective To explore the effect of surface electromyography biofeedback combined with the routine comprehensive rehabilitation treatment on walking ability of stroke patients with hemiplegia. Methods 80 stroke patients with hemiplegia were randomly divided into control group (n=40) and treatment group (n=40). All the patients received routine comprehensive rehabilitation treatment. The treatment group received electromyography biofeedback electrostimulation in addition. Fugl-Meyer Assessment was used to assess motor and balance function; active range of movement of ankle joint, the integrated electromyogram (iEMG) of isometric contraction of anterior tibialis muscle under maximum ankle dorsiflexion and Holden walking function were determined before and 8 weeks after treatment. Results 8 weeks after treatment, the scores of motor and balance function, the active range of movement of ankle, the iEMG, and Holden walking function significantly improved in both groups (P<0.001), and improved more in the treatment group than in the control group (P<0.05).Conclusion The electromyography biofeedback combined with routine comprehensive rehabilitation treatment can improve ankle motion control ability and walking ability of stroke patients with hemiplegia.

Objective To investigate the clinical applicability and different characteristics of three commonly used diagnostic methods for drug-induced liver injury from the two aspects of liver injury induced by Western medicine and liver injury induced by traditional Chinese medicine. Methods A prospective cohort study was performed for 289 hospitalized patients with acute drug-induced liver injury who were admitted to The Fifth Medical Center of Chinese PLA General Hospital from January 2015 to December 2020 and did not receive integrated traditional Chinese and Western medicine therapy, among whom 187 patients had herb-induced liver injury and 102 had Western medicine-induced liver injury. The 289 patients were diagnosed by the integrated evidence chain (IEC), Roussel Uclaf Causality Assessment Method (RUCAM), and the Structured Expert Opinion Process (SEOP) method, and related data at acute onset were collected, including general information, latency period, detailed medication, and laboratory markers such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase, alkaline phosphatase, and total bilirubin. A statistical analysis was performed to investigate the consistency between IEC, RUCAM, and SEOP in the diagnosis of Western medicine-induced liver injury and herb-induced liver injury and their own applicability. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data; the chi-square was used for comparison of categorical data. Results The hepatocellular type was the main type of clinical liver injury in both Western medicine-induced liver injury and herb-induced liver injury, accounting for 81.4% and 74.3%, respectively, and laboratory examination showed higher levels of ALT and AST. Western medicine-induced liver injury cases were diagnosed by IEC, RUCAM, and SEOP, with a clinical diagnosis rate of 65.7%, 100%, and 63.7%, respectively, and the constituent ratio of Western medicine-induced liver injury was 23.2%, 35.3%, and 22.5%, respectively. Herb-induced liver injury cases were diagnosed by these three methods, with a clinical diagnosis rate of 47.6%, 100%, and 29.9%, respectively, and the constituent ratio of herb-induced liver injury was 30.8%, 64.7%, and 19.4%, respectively. The consistency test of the three diagnostic methods showed that in the diagnosis of Western medicine-induced liver injury cases, there was good consistency between IEC and SEOP (Kappa=0.785, P < 0.05), while there was poor consistency between RUCAM and IEC (Kappa=0.149, P > 0.05) and between RUCAM and SEOP (Kappa=0.117, P > 0.05); in the diagnosis of herb-induced liver injury cases, there was poor consistency between RUCAM and SEOP (Kappa=0.066, P > 0.05), while there was good consistency between RUCAM and IEC (Kappa=0.026, P < 0.05) and between IEC and SEOP (Kappa=0.437, P < 0.05). Conclusion The IEC method shows good applicability for both Western medicine-induced liver injury and herb-induced liver injury, and there is good consistency between IEC and SEOP in the diagnosis of Western medicine-induced liver injury cases, while there is a relatively low level of consistency between IEC and SEOP in the diagnosis of herb-induced liver injury. There is poor consistency between RUCAM and the other two methods. In the clinical diagnosis of Western medicine-induced liver injury, IEC, RUCAM, and SEOP should be used in combination to accurately judge the causal relationship between drugs and liver injury.
