The specific functions, stimulating methods and ranges of clinical application of Renying (ST 9) are explored. Because Renying (ST 9) is located in the neck which is a dangerous area, it is perilous if the acupoint is stimulated, so it is mostly forbidden in the past dynasties. In recent years, the main stimulating methods for Renying (ST 9) include acupuncture and press. The keys of acupuncture are to apply correct technique of needle insertion and control the depth and direction of needle. The keys of press are focused on strength and time of press. Renying (ST 9) is effective for vertigo, palpitation, asthma, hemiplegia, aphasia, hysteria, acute attack of pain, hyperplasia of mammary, continuous hiccup, disorder of throat and so on. As long as the acupoint location is accurate, manipulation is careful and stimulating method is correct, not only the safety could be guaranteed, but also the function can be well-played in clinical application.

Objective To investigate the gene expression of methyl-CpG-binding protein 2 (MeCP2) and methyl-CpG-binding domain 2 (mbd2) in patients with systemic lupus erythematosus(SLE) and their significance in the pathogenesis of SLE. Methods Semiquantitative reverse transcriptase-PCR was applied to detect the mRNA expression of MeCP2 and mbd2 in PBMCs obtained from relieved (n=17), active (n=17) SLE patients and healthy controls (n=17). The correlations were further analyzed among these parameters. Results No significant difference was observed in the expression level of MeCP2 mRNA among active SLE patients, relieved SLE patients and healthy controls (P>0.05). The expression of mbd2 in relieved SLE patients was significantly higher than that in health controls (t=12.8, P<0.01), but lower than that in active SLE patients (t=20.0, P<0.01). The expression of mbd2 positively correlated with SLEDAI (r=0.737, P=0.0001) of patients with SLE, and a positive correlation was also observed between the expression of mbd2 and MeCP2 in healthy controls (r=0.550, P=0.0222). Conclusions The expression of MeCP2 and mbd2 may be mutually constrained in normal human, but this relationship seems to be disturbed in patients with SLE.

OBJECTIVETo observe the effect of Zhenqing Recipe (ZQR) on non-alcoholic fatty liver (NAFL), and the expression of hepatic salt-inducible kinase 1 (SIK1) and sterol-regulatory element binding protein-ic (SREBP-lc) in type 2 diabetes rats.

METHODSA rat model of type 2 diabetes was established by high fat/sucrose diet combined with intraperitoneal injection of small dose streptozotocin (STZ) . Modeled rats were randomly divided into the model group, the ZQR group, and the metformin group, 8 in each group. Eight rats were recruited as a normal control group. ZQR at the daily dose of 12 g crude drugs/kg was administered to rats in the ZQR group by gastrogavage. Metformin suspension at the daily dose of 150 mg/kg was administered to rats in the metformin group by gastrogavage. Equal volume of distilled water was administered to rats in the normal control group and the model group. All medication lasted for 12 weeks. The levels of fasting blood glucose (FBG), free fatty acid (FFA), serum triglyceride (TG), serum total cholesterol (TC), serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected. The body weight and wet liver weight were weighed, and the liver weight index calculated. The liver TG content was measured. The pathological changes of liver and the expression of SIK1 were observed by HE staining and immunohistochemistry. The mRNA and protein expression of SIK1 and SREBP-1c were detected using RT-PCR and Western blot.

RESULTSCompared with the normal control group, FBG, FFA, TG, TC, ALT, AST, liver weight index, and liver TG contents significantly increased (P < 0.01); liver steatosis was severe, the mRNA and protein expression of SIK1 obviously decreased (P < 0.01); mRNA and protein expression of SREBP-1c increased (P < 0.01). After drug therapy, compared with the model group, FBG, FFA, TG, TC, ALT, AST, and liver weight index significantly decreased, liver TG contents significantly decreased, the mRNA and protein expression of SIK1 obviously increased, while mRNA and protein expression of SREBP-1c obviously decreased (P < 0.05, P < 0.01) in the ZQR group and the metformin group (P < 0.05, P < 0.01); and the pathological changes were also improved. All the indices were improved more in the ZQR group (all P < 0.05).

CONCLUSIONIn this experiment, we found that the expression of SIK1 decreased in NAFL rats with type 2 diabetes. ZQR could alleviate lesion of NAFL type 2 diabetes rats possibly by up-regulating hepatic SIK1 expression at mRNA and protein levels.

Objective To investigate the clinical utility of anti-dsDNA antibody in the diagnosis of systemic lupus erythematosus (SLE).Methods Total and high affinity anti-dsDNA antibodies of 431 serum samples were measured by total and high affinity anti-dsDNA antibody EIA kits.Modified SLE disease activity index (M-SLEDAI) was scored for each SLE patients at the time of serum collection.The agreements between total and high affinity anti-dsDNA EIA tests and the correlation of anti-dsDNA antibody levels with disease activity and clinical manifestations were analyzed.Statistical analysis was performed using x2 test,Spearman correlation,Mann Whitney U test & Fisher exact,Student t test.Results ① The overall agreement between total and high affinity anti-dsDNA antibodies was 93.3％,and the total agreement of SLE patients was 89.6％.Twenty-two out of 23 (95.7％) SLE patients with positive total anti-dsDNA antibody but high affinity antidsDNA antibody were inactive with the M-SLEDAI score less than 4.Four patients with other autoimmune diseases had positive total anti-dsDNA antibody but negative on high affinity anti-dsDNA antibodies.② The total and high affinity anti-dsDNA antibody levels were significantly positively correlated with disease activity (M-SLEDAI) and negatively correlated with serum C3 and C4 levels (P＜0.01).③ The ratio of high affinity to total anti-dsDNA antibody was significantly higher in patients with M-SLEDAI ≥4 or with active kidney damage (P＜0.01).Conclusion Both total and high affinity anti-dsDNA antibodies are significantly correlated with SLE disease activity and kidney damage.However,the high affinity anti-dsDNA antibody may be more specific for active SLE and helpful in the differential diagnosis with other autoimmune diseases.High affinity anti-dsDNA antibody is more valuable in monitoring SLE disease activity status,especially on kidney damage,compared to total anti-dsDNA antibodies.

Objective To explore the relationship between sperm DNA fragmentation rates and male infertil-ity.Methods Case -control study was used .Sperm DNA fragmentation rates were compared between the primary infertile males for unknown reasons (n=126) and the males whose spouses undergoing delivery in three months (n=100).Results Sperm DNA fragmentation rate of the research group was (11.95 ±4.89) %.Sperm DNA fragmenta-tion rate of the control group was (10.07 ±3.56) %.Significant difference was found between the two groups on sperm DNA fragmentation rate(t=-3.326,P=0.001).The 226 men were divided into group A with sperm DNA fragmentation rates<10%(n=130) and group B with sperm DNA fragmentation rates≥10%(n=96).The percent-age of male infertility in group A was significantly lower than that in group B (50.00%vs 61.62%) (χ2 =4.105, P=0.043).Conclusion Correlation is found between sperm DNA fragmentation rates and male infertility .
