Aim To investigate the effects of Shaoqiduogan(SQDG)on cellular immunity in mice with delayed-type hypersensitivity(DTH). Methods DTH model induced by 2, 4-dinitrochlorobenzene(DNCB)and cyclophosphamide(Cy)suppressed and potentiated DTH model were used. SQDG(30, 60 and 120 mg ? kg-1)were given intragastrically(ig)once daily for 7 consecutive days. Concanavalin A(Con A)-induced T cells proliferation was measured by MTT assay. The activity of IL-2 in culture supernatants of Con A-induced T cells proliferation was measured by testing its ability to support the proliferation of Con A stimulated thymocytes which was detected by MTT assay. Results In mice with DTH, SQDG(120 mg?kg-1)reduced ear swelling, thymus index, Con A-induced T cells proliferation and the activity of IL-2 in culture supernatants of Con A-induced T cells proliferation. The suppression and potentiation of DTH in mice were induced by given an intraperitoneal(ip)injection of Cy at the dose of 150mg?kg-1 on primary sensitization day and 250 mg?kg-1 three days before primary sensitization. SQDG(60 and 120 mg?kg-1)upregulated ear swelling, Con A-induced T cells proliferation and the activity of IL-2 in culture supernatants of T cells from mice with Cy-suppressed DTH; and downregulated levels of the aforementioned indexes in mice with Cy-potentiated DTH. Conclusion SQDG possesses a dual modulatory effect on cellular immunity in mice.

Objective To investigate the effects of Xuebijing injection on the production of ICAM-1 and its counterreceptor(LFA-1)in ANP of rats at different time points.Methods ANP was induced by multiple points in- jection of 5% chenodeoxycholic acid into the pancreas,followed by ligation of pancreatic duct.Expressions of ICAM- 1 at different time points were assessed by immunohistochemistry method,the expressions of LAF-1 on neutrophils at different time points were detected by flow cytometer.The effect of Xuebijing injection was also evaluated by de- tecting the output of ascitic fluid,amylase level and histological changes in pancreas and lungs.Results The expres- sions of ICAM-1 in pancreas and lung of Xuebijing injection group decreased significantly than those in ANP group at most time points during the research period(P

MIC.RESULTS The bacteriostatic/bactericidal CFR of 0.5g q8h imipenem/cilastatin and 0.5g q8h meropenem were the highest(100%);that of 3.375g q4h sodium piperacillin/tazobactam sodium against ESBLs-producing E.coli was above 90%;the CFRs of ceftriaxone(1g q24h,2g q24h),ceftazidime(1g q8h,2g q8h),cefepime(1g q8h,1g q12h,2g q8h) and cefoperazone sodium/sulbactam(0.5g q8h,1g q8h,2g q8h) against ESBLs-producing strains were clearly less than those of non-ESBLs-producing ones,and the CFRs could not be effectively improved with the dose and frequency increased.CONCLUSIONS The PK/PD simulation is useful to optimize the regimen of anti-infective treatment,and guide its dosing accurately.

Objective To investigate the prevention and mechanism of Extracorporeal shock wave lithotripsy(ESW) induced renal Injury by pre-treating kidneys with low-energy shock waves(LESW).Methods Forty healthy female domestic rabbits were surgically managed to the mono-nephron models and random divided into 4 groups consisting of ten each: Control,LESW,ESW and ESWL plus LESW pretreated groups.LESW group received 100 LESW,ESW group received 1500 standard ESW,and same dose on ESW group except 100 LESW pretreatment in ESW plus LESW pretreated group.The rabbit kidney tissues were obtained 24 hours after ESW.Activity of superoxide dismutase(SOD) and malondialdehyde(MDA) levels in the renal tissue,and the level of N-acetyl-β-D-glucosaminidase(NAG) in urinary were measured.Renal cell apoptosis was detected by TdT-mediated dUTP Nick End Labelling(TUNEL).Results The MDA,the urinary level of NAG and rate of apoptosis in the LESW groups were reduced(P<0.01),and the activity of SOD increased significantly(P<0.05) as compared with ESW group,and these changes in LESW group had no statistics difference compared with the control group(P>0.05).Conclusions LESW pretreatment protocol substantially limits the renal injury that often caused by ESW.LESW may suppress oxidative stress and antagonize the process of renal cellular apoptosis.

Objective To observe the clinical effect of abdominal Tuina and acupuncture in treating Swiss generalized anxiety disorder (GAD). Methods 80 patients of GAD caused by liver depression-qi stagnation were randomly recruited into a treatment group and a control group, 40 patients in each. The treatment group was treated with abdominal tuina & acupuncture; while the control group was treated with acupuncture exclusively. Clinical effects and hamilton anxiety scale (HAMA) score were observed in both groups before and after the treatment. Results ①There was significant difference in total efficacy between the two groups CP<0.05), and the treatment group was better than the control group. ②The HAMA score of the two groups after the treatment was lower than that before the treatment, and the difference was significant (P< 0.05). There was also significant difference of HAMA score between the two groups after the treatment (/><0.05), with the treatment group showing better results than the control group. Conclusion Abdominal tuina combined with acupuncture has sound effects in treating Swiss GAD due to liver depression-qi stagnation.

Objective To explore the influence on the JNK signal transduction pathway by BaiHui-QuBin Scalp-acupuncture in rats of experimental acute intercerebral hemorrhage. Methods 192 healthy Wistar male rats were assigned into 3groups randomly:model group, model add pinprick group (to abbreviate:pinprick group), model add suppressor group(to abbreviate:suppressor group) ,containing 60 rats in each. All rats were induced be the intercerebral hemorrage model. Another 12 rats were assigned as the matched blank group. The pinprick group were acupunctured on the "Baihui" penetrating "Qubin". The influence surrounding the hamatoma of the proteinum expression of p-JNK of each group in deferent time phase point with the method of Western blot was observed. Results The results of expression of the proteinum p-JNK with the method of Western blot: all the rats after being made model appeared the phenomenon of the expression of p-JNK of rat's brain tissue surrounding the hematoma and increased to the peak in 2 days,but decreased gradually in 7days. In the same time phase point,compared with the model group,the expression of p-JNK of the pinprick group and the suppressor group were lower obviously (P ＜ 0.01). The pinprick group compared with the suppressor group, the expression of p-JNK showed no significant difference (P ＞ 0.05). Conclusion The therapy of BaiHui-QuBin Scalp-acupuncture could block the JNK signal tranaduction pathway, inhibit the expression of the proteinum p-JNK and so on have the function of protecting the nerve cell and inhibiting apoptosis.

Objective To investigate the level of uncertainty of illness and social support state in patients with prediabetes,and to discuss the correlation between the two.Methods 243 cases with prediabetes were analyzed by Uncertainty in Illness Scale and Social Support Rating Scale.Results There was a middle uncertainty in the elderly patients with prediabetes.The objective support,sabjective support,social support utilization degree and social support score were negatively related to the complexity of uncertainty(r--0.419,-0.433,-0.390 and-0.421,respectively,all P＜ 0.05).Conclusions Medical staff should evaluate the uncertainty in illness in elderly patients with prediabetes and conduct nursing intervention accordingly,in order to reduce the uncertainty,increase social support,and ultimately improve the quality of life.
