A quantitative analytical method of ultra-high performance liquid chromatography (UPLC) was developed for simultaneously determining twelve components in Tibetan medicine Zuozhu Daxi. SIMPCA 12.0 software was used a principal component analysis PCA) and partial small squares analysis (PLSD-DA) on the twelve components in 10 batches from four pharmaceutical factories. Acquity UPLC BEH C15 column (2.1 mm x 100 mm, 1.7 µm) was adopted at the column temperature of 35 °C and eluted with acetonitrile (A) -0.05% phosphate acid solution (B) as the mobile phase with a flow rate of 0. 3 mL · min(-1). The injection volume was 1 µL. The detection wavelengths were set at 210 nm for alantolactone, isoalantolactone and oleanolic; 260 nm for trychnine and brucine; 288 nm for protopine; 306 nm for protopine, resveratrol and piperine; 370 nm for quercetin and isorhamnetin. The results showed a good separation among index components, with a good linearity relationship (R2 = 0.999 6) within the selected concentration range. The average sample recovery rates ranged between 99.44%-101.8%, with RSD between 0.37%-1.7%, indicating the method is rapid and accurate with a good repeatability and stability. The PCA and PLSD-DA analysis on the sample determination results revealed a great difference among samples from different pharmaceutical factories. The twelve components included in this study contributed significantly to the quantitative determination of intrinsic quality of Zuozhu Daxi. The UPLC established for to the quantitative determination of the twelve components can provide scientific basis for the comprehensive quality evaluation of Zuozhu Daxi.

OBJECTIVETo explore the effects of mycoplasma and chlamydia infections on tubal infertilityand to assess the antibiotic susceptibility and resistance of female urogenital, and consequently to guide clinical rational drug use.
METHODS327 tubal infertility women as infertility group and 286 healthy pregnant women as control group were randomly selected, detected chlamydia trachomatis (CT), ureaplasma urealyticum (UU) and mycoplasma hominis (MH) in cervical secretions and drug resistance of UU and MH.
RESULTSCT infection rates (14.99%), UU infection rates (23.24%), UU + MH infection rates (29.05%),CT + UU + MH infection rates (9.17%) and total infection rates (88.99%) in infertility group is higher than those (order: 2.80%, 6.99%, 8.39%, 4.55%, 29.02%) in the control group, comparisons of two groups are statistically significant differences (P < 0.05), the susceptibility of UU to roxithromycin (sensitivity is 96.05%), josamycin (sensitivity is 96.05%), tetracycline (sensitivity is 82.89%), vibramycin( sensitivity is 92.11%) and clarithromycin (sensitivity is 96.05%) were relatively high and low to ciprofloxacin and acetyl spiramycin. The susceptibility of MH to josamycin (sensitivity is 95.83%), vibramycin (sensitivity is 91.67%), minocin (sensitivity is 83.33%) and actinospectacin (sensitivity is 75.00%) were relatively high and low to erythromycin, azithromycin, roxithromycin and clarithromycin. UU + MH was only sensitive to josamycin (sensitivity is 90.52%), high resistance (77.89% -91.58%) to erythromycin, azithromycin, acetyl spiramycin, ciprofloxacin, ofloxacin, azithromycin and clarithromycin.
CONCLUSIONInfection of CT, UU, MH and tubal infertility have certain relevance,the rates of CT, UU and MH infection in tubal infertility patients higher than fertile people. For many commonantibacterial drugs, UU, MH and UU + MH has strong resistance, the etiology detection and using adapted antibios should be taken seriously in clinical treatment.

OBJECTIVETo investigate the inhibition mechanisms of BAY11-7082 (IkappaB-alpha phosphorylation inhibitor) and Lactacystein (proteosome inhibitor) in CD154-induced NF-kappaB activation.
METHODSWe used recombinant CD154 to stimulate EBV/LMP1 negative Ramos B cell and observed the effects of BAY11-7082 and Lactacystein in CD154-induced NF-kappaB luciferase activation, phosphorylation and degradation of IkappaB-alpha, phosphorylation of p65, and nuclear translocation of NF-kappaB subunits upon CD154 stimulation.
RESULTSBoth BAY11-7082 and Lactacystein abrogated CD154-induced NF-kappaB luciferase activation in Ramos cells. While CD154-induced phosphorylation of p65, phosphorylation and degradation of IkappaB-alpha, and nuclear translocation of p50, p65, and c-Rel were all blocked by BAY11-7082; Lactacystein only inhibited degradation of IkappaB-alpha and p65 nuclear translocation.
CONCLUSIONBAY11-7082 and Lactacystein inhibit CD154-induced NF-kappaB activation through different mechanisms.

This study aims to analyze the molecular epidemiological characteristics of HIV-1 strains prevailing among men who have sex with men (MSM) in Beijing, China. The pol gene fragments from 250 newly diagnosed HIV-1-infected MSM individuals during 2006-2010 in Beijing were amplified by RT-nested PCR, sequenced, and phylogenetically analyzed. HIV-1 pol gene from 189 individuals were amplified and analyzed; 81 (42. 9%), 3 (1. 6%), 2 (1.0%), 88 (46. 6%), and 15 (7.9%) individuals were infected with HIV-1 subtypes B, B', C, CRF01_AE, and CRF07_BC, respectively. The subtypes B and CRF01_AE could both be grouped into two clusters, and CRFO7_BC strains shared high homology and were presumed to originate from a common ancestor. The HIV-1 circulating in MSM in Beijing had a lower genetic diversity than in heterosexuals. The HIV-1 epidemic (2006-2010) in MSM in Beijing was actually a rapid spread of HIV-1 CRF01 AE and B, or rather native strains of the two viruses.

OBJECTIVETo explore the correlation between hOCT1 polymorphism and imatinib mesylate (IM) effectiveness in chronic myelogenous leukemia(CML) patients, and to provide for the clinical individual personalized therapy.
METHODSFifty-three CML and 23 non-CML patients were enrolled in this study. Blood or bone marrow samples were collected. Amplification refractory mutation system (ARMS)-polymerase chain reaction was used to amplify the polymorphisms gene segment of hOCT1-P283L, R287G and M408V and their frequencies were statistically analysed. With clinical outcomes, the correlation between hOCT1 polymorphism and IM effectiveness in CML was analyzed.
RESULTS(1) For 74 Han Chinese, the allele frequencies of hOCT1-P283L, R287G and M408V were 39.86%, 29.05% and 45.27%, respectively. (2) The genotypes of hOCT1-P283L, R287G and M408V in 2 Tibetan Chinese were CC, CC, AG and CC, CG, AG, respectively. (3) In the CML patients with IM optimal response, the frequencies of 283T and 287G allele were predominant (P<0.05). No significant difference was found in the frequency distribution of hOCT1-M408V genotype and allele among the 3 different response groups (P>0.05).
CONCLUSION(1) Three single nucleotide polymorphisms (cSNP) P283L, R287G and M408V were found in the hOCT1 gene from 76 Chinese. (2) hOCT1 gene polymorphism is associated with the long-term molecular response of CML patients received IM therapy, indicating that the polymorphisms of hOCT1-283T, 287G may be good predictors for IM response. (3) There is no correlation between the polymorphisms of hOCT1-P283L, R287G, M408V and secondary IM resistance in CML patients.

Objective: To explore the expression of SLAMF6 on CD8(+) T cells in patients with severe aplastic anemia (SAA) and its correlation with disease immune status. Methods: By flow cytometry (FCM), SLAMF6 expression level in peripheral blood CD8(+) T cells was detected in 21 patients with SAA and 15 normal controls respectively from February 2017 to April 2018. The correlation between SLAMF6 expression level and hematopoietic functions, including HGB, PLT, the neutrophil granulocyte and reticulocyte absolute value in peripheral blood, hyperplasia degree (percentage of granulocytes, erythrocytes, lymphocytes and megakaryocytes in bone marrow) and perforin, granzyme B, IFN-γ expression level in CD8(+) T cells were evaluated. To further confirm the effect of SLAMF6 on CD8(+) T cells, anti-SLAMF6 Ab was used to block SLAMF6 pathway (IgG as control), and FCM was used to detect the perforin, granzyme B, and IFN-γ production of CD8(+) T cells. Results: The expression of SLAMF6 on CD8(+) T cells in untreated SAA patients[(56.29±12.97)%]was significantly lower than that of normal controls[(80.96±7.36)%](t=-7.672, P<0.001). The expression of SLAMF6 on CD8(+) T cells in SAA patients were positively correlated with the HGB, PLT, the neutrophil granulocyte and reticulocyte absolute value in peripheral blood, percentage of granulocytes, erythrocytes in bone marrow (all P<0.05), but they were negatively correlated with the percentage of lymphocytes in bone marrow, and the expression of perforin, granzyme B, and IFN-γ of CD8(+) T cells (all P<0.05). After blocking SLAMF6 pathway by anti-SLAMF6 Ab, the expression levels of perforin, granzyme B and IFN-γ in SAA patients were significantly higher than those in the untreated group, and the differences were statistically significant (all P<0.05). Conclusions: SLAMF6 is significantly down-regulated on CD8(+) T cells in SAA patients, which may act as a negative immunoregulatory molecule participating in the mechanism of SAA by affecting the functional molecules secretion on CD8(+) T cells.

Objective To understand the epidemiological characteristics and the influencing factors of Japanese encephalitis (Abbreviated JE) at different periods in Hainan province, and to provide evidence for JE control strategies. Methods Data on JE had been collected since 1952 and related incidence, mortality, fatality rates of JE and the rate of JE vaccination were calculated for four periods: the natural epidemic period (1952-1978), period for inactivated JE vaccine promotion (1979-1986), national immunization program period (1987-1990) and the promotion of live-attenuated JE vaccine period (1991-2007). History on the immunity of JE and data from the monitoring programs on cases and insect vectors were also analyzed. Results The average annual incidence in natural epidemic period was 7.12/100 000, which was also the highest among the 4 periods with the mortality rate as 0.89/100 000. The average annual incidence was 0.11/100 000 which was the lowest while the mortality rate was 0.01/100 000 in the period when live-attenuated JE vaccination was under promotion. Since the establishment of JE surveillance system was set up in Hainan province in 2002, the specimen collection rate of JE reported suspected cases had reached 92.8%, while the incidence of confirmed JE cases fluctuated between 0.05/100 000 and 0.2/100 000. Of the confirmed cases, 86% did not have clear history of JE vaccination. The annual average protective rate reached 95.69% in 2004-2007. The density of insect vectors was high in Hainan province. The infection rate of JE in host animal swine, kept rising from April to October, and in some surveillance points, the rate reached 99.3%. The density of insect vector plotted in trans-curve with the infection of host animals. Conclusion The application of live-attenuated JE vaccine was found to have had significant protective effect on JE in susceptible children. It helped reducing the incidence and controlling the epidemics of JE. It appears feasible to include live-attenuated JE vaccine into the expanded immunization program.
