To establish a new method for simultaneously determining the content of five gingerol compounds in different processing degrees of ginger charcoal and PCA principal component analysis was conducted for analysis. Samples were analyzed on Ultimate TM XB-C18 column (4.6 mm x 250 mm, 5 μm) , with acetonitrile (A) -0.1% phosphoric acid solution (B) as mobile phase for gradient elution. Detection wavelength was set at 280 nm. The flow rate was 0.6 mL x min(-1) and the column temperature was 30 degrees C. The five compounds were separated well and showed good linearity (r ≥ 0.999 7) within the concentration ranges tested. The average value for recoveries was between 98.86% - 101.5% (RSD 1.4% - 2.9%). The contents of five compounds showed difference among different processing degrees of ginger charcoal. Zingiberone had the highest content in the standard carbon, and the content of gingerol was decreased as the deepening of processing degree. Different processing degrees of ginger charcoal were classified into three groups with PCA, and provided scientific basis for establishing the quality standards of ginger charcoal.

Objective To investigate the clinical therapeutic effect of filiform fire needling on tennis elbow.Method Eighty patients with tennis elbow were randomly allocated to a filiform fire needling group of 30 cases, a block group of 20 cases and an electroacupuncture group of 30 cases. The treatment group received. Pain severity was scored using the VAS after one and two weeks and one month of treatment. The therapeutic effects were evaluated and compared after one month of treatment.Result The total efficacy rate was 93.3% in the filiform fire needling group, 60.0% in the block group and 50.0% in the electroacupuncture group; there was a statistically significant difference among the three groups (P<0.05). There was a statistically significant difference between the filiform fire needling and block groups (P<0.05) and between the filiform fire needling and electroacupuncture groups (P<0.05) but no significant difference between the block and electroacupuncture groups (P>0.05). The VAS score decreased significantly in the block group (P<0.05) but did not in the filiform fire needling and electroacupuncture groups (P>0.05) after one week of treatment compared with before. The VAS score decreased significantly in the filiform fire needling and block groups (P<0.05) but did not in the electroacupuncture group (P>0.05) after two weeks of treatment compared with before. There was no statistically significant posttreatment difference in the VAS score between the filiform fire needling and block groups (P>0.05) but there was such a difference between the filiform fire needling or block group and the electroacupuncture group (P<0.05). There was a statistically significant difference in the VAS score in the filiform fire needling and block groups (P<0.01) and also in the electroacupuncture group (P<0.05) between before and after one month of treatment. There was a statistically significant difference in the VAS score after one month of treatment between the filiform fire needling group and the block or electroacupuncture group (P<0.05) and between the block and electroacupuncture groups (P<0.05). The results of the study showed that filiform fire needling, local drug blockage and electroacupuncture all had clinically a better therapeutic effect on tennis elbow and a better improving effect on the symptoms in the patients. Filiform fire needling produced a marked therapeutic effect. Its effect was superior to those of block therapy and electroacupuncture.Conclusion Filiform fire needling is a definitely effective way to treat tennis elbow.

To investigate the therapeutic effects and associated complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT). 40 patients with various malignant hematopoietic diseases received allo-PBSCT. The preparative regimens were based on BUCY2 or modified BUCY2. The acute graft-versus host disease (aGVHD) was prevented by cyclosporin A and short-term MTX regimen in all patients. Two patients from donors with one fully mismatched HLA on DRB1 locus and 4 from unrelated donor also administered Zenapox (CD25 MAb) at dosage of 1 mg/kg every day on the day before transplantation and day 4 after transplantation. These 6 patients were also treated with mycophenolate mofetil (MMF). Transfusion of the donor cells: The median of the transfused nucleated cells was 5.38 x 10(8)/kg and that of the CD34+ cells was 7.8 x 10(6)/kg respectively. All the patients gained hematopoietic reconstruction except one who died of infection before engraftment. Seven patients got II degrees-IV degrees aGVHI) and the incidence was 17.5%. Fourteen patients got cGVHD and the incidence was 53.8% in the patients who survived over 6 months. Twenty-eight patients had fever or other characteristics of infection. The median follow-up time was 13.8 months. The incidence of transplantation related mortality (TRM) was 17.5% and 2 patients relapsed (5.0%). It was concluded that allo-PBSCT can reconstruct hematopoiesis quickly and is a favorable therapeutic method for leukemia.

There are many different opinions about the taxonomy of plant pathogenic coryneform bacteria since they were departed from genus of Corynebacteria. In recent years, they were classified into 5 genus, including Clav-ibacter, Curtobacterium, Arthrobacter, Rhodococcus and Rathayibacter. Some new points of view about their taxonomy have been published thereafter. The changing of taxonomy is maily because of the methods'altering from old to new molecular and polyphasic taxonomy, and the latter is in continuously development. Taxonomy of plant pathogenic coryneform bacteria somehow depends on the cooperation of phytopathologists, microbilogists and other scientists.

OBJECTIVETo explore the effect of Qiling Decoction (QD) combined highly active antiretroviral treatment (HAART) on expression levels of peripheral blood Th17 and Treg cells in HIV/AIDS patients.

METHODSTotally 55 HIV/AIDS patients were randomly assigned to the treatment group (28 cases) and the combination group (27 cases). Besides, 21 HIV negative patients were recruited as the healthy control group. Those in the treatment group received HARRT alone, while those in the combination group received HAART combined QD. The observation lasted for 24 weeks. Meanwhile, according to peripheral blood CD4+ T cell counts before treatment, HIV/AIDS patients were assigned to three subgroups. For patients in subgroup 1, 1 cells/microL < CD4+ T cell counts < or = 100 cells/microL; For patients in subgroup 2, 101 cells/microL < CD4+ T cell counts < or = 200 cells/lL; For patients in subgroup 3, 201 cells/microL < CD4+ T cell counts < or = 350 cells/microL. Expression of peripheral blood Th17 and Treg cells, and number of CD4+ T cell counts were detected using flow cytometry (FCM)in HIV/AIDS patients at the pre-treatment baseline, week 4, 12, and 24, as well as those in the healthy control group.

RESULTSCompared with the healthy control group, CD4+ T cell counts and the baseline expression level of Th17 cells in the peripheral blood of HIV/AIDS patients significantly decreased, the expression level of Treg cells significantly increased P < 0.01). Compared with before treatment in the same group, CD4+ T cell counts all increased at week 4, 12, and 24 in the two treatment groups, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference in the effective rate at various CD4+ T cell levels between the two groups (P > 0.05). There was no statistical difference in expression levels of Th17 and Treg cells between the combination group and the treatment group at any time point (all P >0.05). The Th17/Treg ration significantly increased in the combination group after 24 weeks of treatment, showing statistical difference when compared with the treatment group (U = 2.135, P = 0.038).

CONCLUSIONQD could improve the immune balance of Th17/Treg cells, which might be one of its mechanisms for improving HIV/AIDS patients' immunity.

Objective To investigate the effect of low frequency electric deep brain stimulation on amygdale kindling in rats.Methods The amygdale kinkling model of rats was established by operation on the brain.The effects of low frequency deep brain electric stimulation used alone or in combination with anti-epilepsy drugs were ob- served in terms of severity of seizure attack reflected by Racine's scale and afterdischarge duration recorded in electro- encephalogram.Results Fifteen minutes of low frequency electric stimulation at 1 Hz and 100 to 350?A effective- ly inhibited amygdale kindling as demonstrated by a significant decrease of afterdischarge duration,and decreased the severity of seizure attack (P

0.05).The protein and mRNA expression of MIP-2 in high glucose group significantly increased after culture for 4 h,and guadually decreased then.The protein and mRNA expression of MCP-1 began to increase significantly after culture for 8 h,reached peak at 12 h,and slightly decreased after culture for 24 and 48 h. Conclusion High glucose promotes the protein and mRNA expression of MIP-2 and MCP-1 from mouse peritoneal macrophages cultured in vitro,which indicates that high glucose may delay the wound healing by increasing the expression of chemokines in diabetic mice.

Objective To explore the association between glycated hemoglobin (HbA1c) level at admission and coronary plaque characteristics under intravenous ultrasound (IVUS) study in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS). Methods 118 patients with NSTE-ACS were divided into the low(HbA1c ≤ 5.6％), medium(HbA1c 5.7％-6.4％)and high(HbA1c ≥ 6.5％)level groups based on admission HbA1c. IVUS was performed in all target lesions. Results As compared with the other two groups, patients with high level HbA1c had higher mean body weight index, higher co-morbidities of diabetes mellitus, dyslipidemia and non-ST-elevation acute myocardial infarction.The high HbA1c level group had more diffuse coronary atherosclerosis ,increased plaque burden and higher rates of positive remodeling, soft plaque and plaque rupture. Conculsions The HbAlc level of admission is associated with plaque vulnerability in NSTE-ACS patients.
