Objective To understand current prevalence of fluorosis, of drinking tea type in Pengyang County of Ningxia to offer scientific basis for preventing and curing, monitoring, health education. Methods Four towns were chosen as investigating spots in Pengyang County of Ningxia in 2007, from each 50 children aged 8-12 year old and 50 adults who either had tea or did not were investigated. Dean method was used to measure dental fluorosis of children and adult; meanwhile fluoride content in water, urine and drinking tea was tested using the fluoride ionic electrode method and that in brick tea using water immersion electrode method. χ2 testing, analysis of variance, u test, q test were performed. Results In adult drink tea group, control group, and children, the detaction rate of dental fluorosis were respectively 24.75%(99/400),9.5%(38/400)and 15.96%(71/445), obviously higher in drink tea group than the control group(χ2= 32.73, P<0.05). Urine average concentration of fluoride was (3.38±2.37), (2.09±1.33 ). (1.41±0.67)mg/L, obviously higher in drink tea group than the control group(u= 9.49, P<0.05). In 4 investigation spots tea fluoride averaged at (3.63±2.05)mg/L, fluoride content in drinking water was averagely (1.01±0.49) mg/L, with that of Wangwa Town [(1.31±0.33)mg/L] exceeding the national standard for drinking water (1.0 mg/L), where dental fluorosis rate was higher and fluoride content was higher than that in 3 other investigation spots (P<0.05). Conclusions Residents in Pengyang County in Ningxia who drink brick tea can cause accumulation of fluorine to poison in Ningxia, leading to fluorosis of drinking tea type; Wangwa Town have both drink tea and water fluorine poison.

OBJECTIVETo observe the effect of combined therapy of Neiyi pill (NP) and Neiyi enema (NE) on endometriosis and its effect on serum levels of endometrial antibody (EMAB) and carcinoembryonic antigen 125 (CA125).

METHODSFifty-eight cases with endometriosis were divided into 3 groups randomly, group A (n = 16) treated by NP, group B (n = 24) treated by NP and NE, and group C (n = 18) treated by danazol, all for 3 menstrual cycle with single blind method. The effect was observed and the serum levels of EMAB and CA125 were detected before and after treatment.

RESULTSComparison of the efficacy between the 3 groups showed: there was no remarkable difference between group A and B (P >0.05), both of group A and group B were superior to that of group C (P<0.05). The levels of EMAB and CA125 had no significant changes in all the three groups after treatment.

CONCLUSIONCombined therapy of NP and NE could improve the curative effect on endometriosis, and without obvious effects on serum levels of EMAB and CA125.

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

The purpose of this study was to evaluate the impact of callus induction and culture conditions on secondary metabolic diversity of the callus cell lines of traditional Chinese medicinal plant Glycyrrhiza sp. (Glycyrrhiza) by combined chemical analysis and HPLC fingerprint. These callus induction conditions included two Glycyrrhiza species, two types of explants, light and dark conditions, and two combinations of hormones. The evaluation was firstly based on the contents of total flavonoids in the callus by chemical analysis and one way ANOVA. The content of total flavonoids in callus was significantly (P < 0.05) influenced by Glycyrrhiza species, light condition, and the combination of hormones. The callus was further evaluated using diversity factor based on the comparison of HPLC fingerprints of these callus cell lines. Diversity factor varies significantly for calli induced under different conditions, with the highest being at 0.45 under light condition and combination of hormones. These results provide important knowledge for the selection of suitable callus cell lines for the production of pharmacologically important secondary metabolites or bioactive fractions by in vitro culture of Glycyrrhiza sp.

OBJECTIVETo study the status and influencing factors on sleep quality in some medical college students.

METHODSStratified sampling, pittsburgh sleep quality index (PSQI), self-evaluation depression scale (SDS), self-evaluation anxiety scale (SAS) and self-developed questionnaire of influencing factors on the quality of sleep in medical college students were used. Cumulative odds logistic model was performed to analyze the related factors on the quality of sleep.

RESULTS19.17 percent of the medical college students showed poor quality of sleep and the difference between genders was not statistically significant (P > 0.05). Statistically significant (P < 0.05) difference was seen among different years of students and correlation was found between sleep quality and depression or anxiety (P < 0.0001). Factors influencing on the quality of sleep in medical college students would include: worry of sleep, irregular work/rest, worry on examination, stress, relationship with classmates, self-evaluated health condition, environments of the dormitory and late to bed.

CONCLUSIONInfluencing factors were identified and comprehensive measures should be taken to improve the quality of sleep.

OBJECTIVETo investigate the effect of apatinib, a small-molecule vascular endothelial growth factor receptor-2 tyrosine kinase inhibitor, on the proliferation of human acute myeloid leukemia HL-60 cells and explore the possible mechanism.

METHODSMTT assay was used to assess the cytotoxicity of apatinib in HL-60 cells. The apoptosis and cell cycle changes of the cells in response to apatinib treatment were analyzed by flow cytometry, and Western blotting was used to assay P-Akt and P-Erk1/2 expressions in the cells.

RESULTSApatinib significantly inhibited the proliferation of HL-60 cells in vitro with an IC(50) of 4.96∓0.32 µmol/L. Apatinib treatment significantly increased the apoptotic rate of the cells in a dose-dependent manner, but produced no significant effect on the cell cycle (P>0.05). Western blotting showed that the expressions of P-Akt and P-Erk1/2 decreased in HL-60 cells after a 48-h apatinib treatment.

CONCLUSIONApatinib inhibits the proliferation of HL-60 cells by inducing cell apoptosis probably through the mechanism of inhibiting the expressions of the Akt/Erk1/2 signal transduction pathway.
