OBJECTIVETo study the effect of Weifuchun on inflammation of Helicobacter pylori (Hp)-infected gastric epithelial cells (GES-1) and its correlation with NF-kappaB signaling pathway.

METHODSHp standard home-made strain (CagA +, VacA +) NCTCI 1637 infected GES-1 cells were used. Weifuchun was used as intervention. Weifuchun of different concentrations (5,10, and 20 microg/mL) were screened by MTT assay. A blank group and the model group were set up. Then the growth inhibition rate of drugs on gastric epithelial GES-1 cells was detected with MTT assay. Cell cycle was detected using flow cytometry. The supernatant liquid was separated to detect the contents of IL-8 and IL-4 by ELISA.The protein expression level of NF-kappaB was detected by Western blot analysis.

RESULTSMTT assay indicated significantly inhibitory effect of Weifuchun on GES-1 cells [5% inhibiting concentration (IC5)] was 10 microg/ml in the Weifuchun group. After GES-1 and Hp were cultured together,the contents of IL-8 in the supernatant were more obviously higher in the model group than in the blank group (P < 0.05), and then gradually decreased. After treatment with different concentrations of Weifuchun, the levels of IL-8 in the supernatant were less when compared with the model group at 12, 24, 48, and 72 h (P < 0.05). The decrement was the most significant in the high dose Weifuchun group. The IL-4 level in the supernatant was obviously lower in the model group than in the blank group. It obviously increased in the high concentration Weifuchun group (P < 0.05). There was no statistical difference in the IL-4 level between middle, low concentration Weifuchun group and the blank group (P > 0.05). The protein expression of intranuclear P65 increased and that of IkBalpha decreased 60 min after Hp infection. But the protein expression of intranuclear P65 decreased and the protein expression of IkBalpha increased after intervention of Weifuchun.

CONCLUSIONSWeifuchun adjusted H. pylori induced IL-8 and IL-4 production by gastric epithelial cells through blocking NF-kappaB pathways. Its mechanisms might possibly lie in inhibiting p65 from entry into nucleus and the degradation of IkBalpha. Weifuchun was an effective drug for treatment of Hp correlated chronic gastritis.

This study focused on the intestinal absorption of traditional Chinese medicines (TCM) to reveal the scientific connotation of the compatibility of TCM pairs. The single pass intestinal perfusion (SPIP) was used in rats to compare the absorption of single extracts from Puerariae Lobatae Radix, single extracts from Ginseng Radix et Rhizoma, combined extracts from Puerariae Lobatae Radix and Ginseng Radix et Rhizoma and Puerariae Lobatae Radix and Ginseng Radix et Rhizoma mixture in rats. The content of puerarin, ginsenoside Rg1, ginsenoside Re and ginsenoside Rb1 in liquid were tested by HPLC. The speed constant (Ka) and apparent permeability coefficients (Papp) were calculated and compared. Specifically, the order of puerarin Ka and Papp values from high to low was Ginseng Radix et Rhizoma and Puerariae Lobatae Radix mixture > single extracts from Puerariae Lobatae Radix > combined extracts from Ginseng Radix et Rhizoma and Puerariae Lobatae Radix; the order of ginsenosides Ka and Papp values from high to low was Ginseng Radix et Rhizoma and Puerariae Lobatae Radix mixture > single extracts from Ginseng Radix et Rhizoma > combined extracts from Ginseng Radix et Rhizoma and Puerariae Lobatae Radix. The combined administration of Ginseng Radix et Rhizoma and Puerariae Lobatae Radix may improve the absorption in the intestinal tract.

Objective To understand the willingness to receive human papillomawrus (HPV) vaccination of men who have sex with men (MSM) and the male clients of sexually transmitted disease (STD) clinics and related factors in China.Methods MSM were enrolled from the community through snowball sampling and male clients of STD clinics were enrolled from a sexual health clinic through convenience sampling in Wuxi,China.A questionnaire survey on the subjects' socio-demographic characteristics and the awareness of HPV was conducted.Results A total of 186 MSM and 182 STD clients were recruited.The awareness rates of HPV were 18.4％ and 23.1％,respectively and the awareness rates of HPV vaccination were 10.2％ and 15.4％,respectively.STD clinic clients (70.9％) were more likely to receive HPV vaccination than MSM (34.9％) (x2=47.651,P＜0.01).Only 26.2％ of MSM and 20.2％ of STD clinic clients were willing to receive free HPV vaccination before the age of 20 years.Multivariate logistic regression analysis showed that MSM who had passive anal sex (OR=2.831,95％ CI:1.703-13.526),MSM who never used condom in anal sex in the past 6 months (OR=3.435,95％CI:1.416-20.108),MSM who had been diagnosed with STDs (OR=1.968,95％CI:1.201-8.312) and STD clinic clients who had commercial sex with females in the past 3 months (OR=1.748,95％ CI:1.207-8.539),STD clinic clients who never used condom in commercial sex in the past 3 months (OR=1.926,95％CI:1.343-5.819) and STD clinic clients who had been diagnosed with STDs in past 12 months (OR=2.017,95％CI:1.671-7.264) were more likely to receive free HPV vaccination.Conclusion Sexually active MSM and male clients in STD clinics in China had lower awareness of the HPV related knowledge.Their willing to receive HPV vaccination were influenced by their behavior related factors.It is necessary to strengthen the health education about HPV and improve people's awareness of HPV vaccination.

Background: and Purpose The relationships among interleukin (IL)-10 levels, anxiety, and cognitive status after stroke remain controversial. We aimed to determine the associations of serum IL-10 levels with poststroke anxiety (PSA) and poststroke cognitive impairment (PSCI). Methods: We recruited 350 patients with stroke, of whom only 151 completed a 1-month follow-up assessment. The Mini Mental State Examination (MMSE) and Hamilton Anxiety Scale (HAMA) were used to assess the cognitive status and anxiety, respectively. Serum IL-10 levels were measured within 24 hours of admission. Results: IL-10 levels were significantly lower in the PSA group than in the non-PSA group, and they were negatively associated with HAMA scores (r=-0.371, p<0.001). After adjusting for all potential confounders, IL-10 levels remained an independent predictor of PSA (odds ratio=0.471, 95% confidence interval=0.237–0.936, p=0.032). IL-10 levels were strongly correlated with behavior during interviews, psychic anxiety, and somatic anxiety. Patients without PSCI had higher IL-10 levels were higher in non-PSCI patients than in PSCI patients, and they were positively associated with MMSE scores in the bivariate correlation analysis (r=0.169, p=0.038), and also with memory capacity, naming ability, and copying capacity.However, IL-10 did not predict PSCI in the univariable or multivariable logistic regression. Conclusions Low IL-10 levels were associated with increased risks of PSA and PSCI at a 1-month follow-up after stroke. Serum IL-10 levels may therefore be helpful in predicting PSA.

OBJECTIVETo study the effect of vinorelbine on apoptosis, telomerase activity and expression of hTERT gene in human lung adenocarcinoma cell line Anip973 cells.

METHODSAnip973 cells were cocultured with Vinorelbine at different concentrations and collected at 24 h, 48 h and 72 h after treatment, respectively. The inhibition rate of cell growth was determined by methyl thiazolyl tetrazolium (MTT) assay to evaluate the effect of vinorelbine. The percentage of apoptosis was detected by flow cytometry. The cellular morphology was observed under inverted microscope and electron microscope. Telomerase activity of Anip973 cells was determined by the method of TRAP-PAGE-silver staining. RT-PCR was used to detect the expression of hTERT mRNA.

RESULTSVinorelbine down-regulated the telomerase activity and expression of hTERT gene mRNA, inhibited the growth of Anip973 cells, and induced cell apoptosis in a time- and concentration-dependent manner. Annexin V-FITC assay showed 0.08 µg/ml NVB group could inhibited cell proliferation in 24 hour, and apoptosis rate was (7.37 ± 0.35)%, RT-PCR detection of hTERT mRNA expression in this group was (57.01 ± 1.71), and they were very significantly different from that in the control group (P < 0.01), but telomerase activity was (6.36 ± 0.06), compared with the control group showed no significant difference(P > 0.05). The change of hTERT mRNA expression is more sensitive than telomerase activity. The apoptosis rate, telomerase activity and hTERT mRNA expression of 0.4 µg/ml group and 2.0 µg/ml group were very significantly different from that in the control group (P < 0.01). The telomerase activity of 2.0 µg/ml at 72 hour group was (1.36 ± 0.27), basically completely inhibited, while the apoptosis rate was (74.87 ± 1.88)%, showed the cell apoptosis rate was in a negative correlation with the down-regulation of the hTERT mRNA (r = -0.96046, P < 0.01).

CONCLUSIONSVinorelbine can induce apoptosis in Anip973 cells, and its mechanism of action is related to telomerase activity. The detection of telomerase activity and expression of hTERT gene is useful in predicting prognosis of patients with lung adenocarcinoma.
