Objective To explore the relationship between T lymphocyte subsets and both glioma malignancy and its prognosis, and determine a clinical immunologic index for evaluating preoperative glioma malignancy and its prognosis. Methods The data of 117 inpatients with primary intracranial tumors, including glioma (n=85) and meningioma (n=32), were retrospectively analyzed. Fluorescence-activated cell sorting (FACS) analysis was performed to detect the preoperative contents of T lymphocyte subsets on 32 patients with meningioma and patients with glioma, including 45 high-grade glioma (WHO, grade Ⅲ-Ⅳ) and 40 low-grade glioma (WHO, grade Ⅰ -Ⅱ); and then the differences of their immunologic indexes were analyzed. Based on the detection result of T lymphocyte subsets, patients with glioma were divided into two groups: CD4~+CD8~+<1 and CD4~+CD8~+>1. Follow-up for 3-5 years was performed and the survival difference of these two groups was analyzed. Results Patients with high-grade glioma showed a decreased ratio of CD4~+CD8~+ and an increased value of CD8~+ with significant difference as compared with patients with low-grade glioma (P<0.05); patients with high-grade glioma showed a decreased ratio of CD4~+CD8~+, and an increased value of CD8~+ with statistical significance compared with patients with meningioma (P <0.05); patients with low-grade glioma showed a decreased ratio of CD4~+CD8~+ with statistical significance compared with the patients with meningioma (P<0.05). Patients with glioma showed a decreased ratio of CD4~+CD8~+ and CD4~+, and an increased CD8~+ with statistical significance compared with patients with meningioma (P<0.05). After follow-up for 3-5 years, 48 patients with glioma was found in the CD4~+CD8~+>1 group with 21 death (43.8%) and 31 months as a median survival time; 37 patients with glioma was found in the CD4~+CD8~+<1 group with 23 death (62.2%) and 16 months as a median survival time. The Kaplan-Meier survival curves were analyzed with statistical significance (P<0.05). Conclusion The prognosis is poor in patients with low ratio of CD4~+CD8~+. The preoperative level of T lymphocyte subsets in peripheral blood, correlated to the glioma malignancy, can be considered as an index to evaluate the glioma malignancy and the prognosis in patients with glioma.

OBJECTIVETo study the toxicity features of high glucose on the endothelial cell cycle and the influence of Dan Gua-Fang, a Chinese herbal compound prescription, on the reproductive cycle of vascular endothelial cells cultivated under a high glucose condition; to reveal the partial mechanisms of Dan Gua-Fang in the prevention and treatment of endothelial injury caused by hyperglycemia in diabetes mellitus (DM); and offer a reference for dealing with the vascular complications of DM patients with long-term high blood glucose.

METHODSBased on the previous 3-(4,5)-dimethylthiahiazo (z-y1)-3-5-diphenytetrazoliumromide (MTT) experiment, under different medium concentrations of glucose and Dangua liquor, the endothelial cells of vein-304 (ECV-304) were divided into 6 groups as follows: standard culture group (Group A, 5.56 mmol/L glucose); 1/300 herb-standard group (Group B); high glucose culture group (Group C, 16.67 mmol/L glucose); 1/150 herb-high glucose group (Group D); 1/300 herb-high glucose group (Group E); and 1/600 herb-high glucose group (Group F). The cell cycle was assayed using flow cytometry after cells were cultivated for 36, 72 and 108 h, respectively.

RESULTS(1) The percentage of cells in the G0/G1 phase was significantly increased in Group C compared with that in Group A (P<0.05), while the percentage of S-phase (S%) cells in Group C was significantly reduced compared with Group A (P<0.05); the latter difference was dynamically related to the length of growing time of the endothelial cells in a high glucose environment. (2) The S% cells in Group A was decreased by 30.25% (from 40.23% to 28.06%) from 36 h to 72 h, and 12.33% (from 28.06% to 24.60%) from 72 h to 108 h; while in Group C, the corresponding decreases were 23.05% and 21.87%, respectively. The difference of S% cells between the two groups reached statistical significance at 108 h (P<0.05). (3) The percentage difference of cells in the G2/M phase between Group C and Group A was statistically significant at 72 h (P<0.01). (4) 1/300 Dan Gua-Fang completely reversed the harmful effect caused by 16.67 mmol/L high glucose on the cell cycle; moreover it did not disturb the cell cycle when the cell was cultivated in a glucose concentration of 5.56 mmol/L.

CONCLUSIONSHigh glucose produces an independent impact on the cell cycle. Persistent blocking of the cell cycle and its arrest at the G0/G1 phase are toxic effects of high glucose on the endothelial cell cycle. The corresponding variation of the arrest appears in the S phase. 1/300 Dan Gua-Fang completely eliminates the blockage of high glucose on the endothelial cell cycle.

OBJECTIVETo study the socio-demographic characteristics, acquired immune deficiency syndrome (AIDS) related behaviors of male clients of female sex workers and their determinants.

METHODSContacting subjects through 5 ways including volunteers of female sex workers (FSWs), sexually transmitted disease (STD) clinics, long-distance bus stations, long-distance cargo station while adopting methods as snowballing, employing an anonymous questionnaire. Data was analyzed by logistic regression analysis.

RESULTS(1) The majority of clients were 25-45 years old, married and of junior high school or above educational levels; (2) Among male clients of FSWs, numbers of having had commercial sexual intercourse was between 1 to 240, averaged 24 in the previous year. It significantly related to their occupation and the experience of their friends or colleagues who ever visited female sex workers; (3) 27.98% of them used condom every time during commercial sexual intercourse, which significantly related to the score of knowledge on AIDS, concourse of sex intercourse and inhabitation; (4) 28.36% of them had ever contracted STD, which significantly related to the frequency of commercial sexual intercourse in the previous year, risk awareness of being infected with human immunodeficiency virus, and frequency of condom use during commercial sexual intercourse.

CONCLUSIONThe proportion of always using condom was low among male clients of FSWs, and had had STDs. And it's necessary for active and specific intervention programs to them.

Objective: To study the value of unmethylated cytosine guanine dinucleotide oligodeoxynucleotide (DSP30) and IL-2 in the conventional cytogenetic (CA) detection of the chromosomal aberrations in chronic lymphocytic leukemia (CLL) . Methods: Bone marrow or peripheral blood cells of CLL patients were cultured with DSP30 plus IL-2 for 72 h, following which R-banding analysis was conducted. Fluorescence in situ hybridization (FISH) was performed in 85 patients. CA results were compared with data obtained by FISH. Results: Among 89 CLL patients, the success rate of chromosome analysis was 94.38% (84/89) . Clonal aberrations were detected in 51 patients (51/84, 60.71%) . Of them, 27 (27/51, 52.94%) were complex karyotype. Among 85 CLL patients tested by FISH, chromosomal abnormalities were detected in 74 (74/85, 87.06%) patients, of which 2 (2/74) patients were complex karyotypes, accounting for 2.70%. Of the 85 CLL patients examined by FISH, 50 had abnormal karyotype analysis, 30 had normal karyotype, 5 failed to have chromosome analysis. Among them, 25 cases showed clonal aberrations by FISH assay but normal by CA, and 4 cases were normal by FISH but displayed aberrations in chromosome analysis, and totally 78 (91.76%) cases with abnormality detected by the combination of the two methods. The frequency of 13q- abnormality detected by FISH was significantly higher than that by CA analysis (69.41%vs 16.67%, P<0.001) , while the frequency of 11q-,+12 and 17p- detected by two methods showed no significant difference (P>0.05) . The detection rate of complex abnormalities in conventional karyotype analysis was higher than that in FISH (50.98%vs 2.70%) . In addition, 11 low-risk and 9 intermediate-risk patients according to FISH results showed complex karyotype by cytogenetics, and were classified into high-risk cytogenetic subgroup. Conclusion: DSP30 and IL-2 are effective in improving the detection rate of CA in CLL patients (60.71%) and CA is more effective to detect complex karyotype. However, FISH had a higher overall abnormality detection rate (87.06%) than CA, especially for 13q-. The combination of CA and FISH not only enhanced the detection rate of clonal aberrations to 91.76%, but also provided more precise prognosis stratification for CLL patients, thus to provide more information for clinical implication.

OBJECTIVE: To investigate the changes of bone mineral density (BMD) and serum bone turnover factor in newly diagnosed systemic lupus erythematous (SLE) patients. METHODS: Eighty newly diagnosed SLE patients and 80 age and gender matched healthy controls were enrolled. None of the SLE patients had ever received glucocorticoid, immunosuppressive agents or vitamin D. BMD was measured at radius,lumbar spine and hip by dual X ray absorptiometry (DXA). Bone turnover markers including serum levels of tartrate-resistant acid phosphatase 5b (TRAP5b),bone alkaline phosphatase (BAP) and 25-hydroxy vitamin D3 (25-OH-VD3) were measured by enzyme-linked immunosorbent assay (ELISA). Logistic regression was employed to analyze the risk factors associated with decreased BMD. RESULTS: Mean age of the SLE patients was (32.8±12.4) years, and 85% were female, none of whom were post-menopausal. BMD was significantly reduced in all the measured sites, compared with the healthy controls. Sixteen (20%) of the patients were osteopenic in at least one site measured locations. The serum levels of 25-OH-VD3 were markedly reduced in the newly diagnosed SLE patients than those of the normal controls [(46.1+12.3) nmol/L vs. (25.4+11.2) nmol/L, P<0.001)]. The serum levels of 25-OH-VD3 in the SLE patients with nephritis were much lower than those without nephritis (P=0.04). A significant negative correlation was demonstrated between the serum concentration of 25-OH-VD3 and the disease activity scores as measured by SLE disease activity index (SLEDAI) (r=-0.3,P=0.001). The serum TRAP5b concentration was positively correlated with SLEDAI (r=0.435,P=0.003). Age (P=0.058) and SLEDAI (P=0.085) were probably associated with decreased BMD in Logistic regression analysis. CONCLUSION The study showed reduced BMD in untreated SLE patients. The role of chronic inflammation was of probable importance in bone metabolism.

OBJECTIVE: To evaluate the efficacy and safety of Tongxiening Granules (, TXNG) in the treatment of irritable bowel syndrome with predominant diarrhea (IBS-D). METHODS: A randomized, double-blind, double-dummy, and positive parallel controlled clinical trial was conducted from October 2014 to March 2016. Totally 342 patients from 13 clinical centers were enrolled and randomly assigned (at the ratio of 1:1) to a treatment group (171 cases) and a control group (171 cases) by a random coding table. The patients in the treatment group were administered orally with TXNG (5 g per time) combined with pinaverium bromide Tablet simulator (50 mg per time), 3 times per day. The patients in the control group were given TXNG simulator (5 g per time) combined with pinaverium bromide Tablets (50 mg per time), 3 times per day. The treatment course lasted for 6 weeks. The improvement of Irritable Bowel Syndrome Symptom Severity Score (IBS-SSS) was used to evaluate the primary outcome. Secondary outcomes included adequate relief (AR) rate, Irritable Bowel Syndrome-Quality of Life Questionnaire (IBS-QOL), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and the recurrence rate at follow-ups. Safety indices including the adverse events (AEs) and related laboratory tests were evaluated. RESULTS: Primary outcome: IBS-SSS at baseline, weeks 2, 4, 6 showed no statistical significance in both full analysis set (FAS) and per protocol set (PPS, P>0.05). After 6 weeks of treatment, the total effective rate of IBS-SSS scores in the treatment group (147/171,86.0%) was higher than the control group (143/171, 83.6%) by FAS (P>0.05). In regard to secondary outcomes, after 6-week treatment, there was no significant difference in AR rate, total score of IBS-QOL, improvement of HAMD and HAMA total scores between the two groups (P>0.05). The recurrence rate at 8-week follow-up was 12.35% (10/18) in treatment group and 15.79% (12/76) in control group, respectively (P>0.05). A total of 21 AEs occurred in 15 cases, of which 11 occurred in 8 cases in the treatment group and 10 AEs in 7 cases in the control group. The incidence of AEs had no statistical significance between the two goups (P>0.05). CONCLUSION Tongxiening Granules could relieve the symptoms of patients with IBS-D and the treatment effect was comparable to pinaverium bromide. (No. ChiCTR-IPR-15006415).
