OBJECTIVETo explore the clinical efficacy and action mechanism of acupuncture for premature ovarian failure (POF).
METHODSAccording to prospective cohort study design, 30 cases were included. Based on theory of regulating Chong and Conception Vessels as well as soothing the liver and calming the nerves, acupuncture at Guanyuan (CV 4), Dahe (KI 12), Taixi (KI 3), Taichong (LR 3), Baihui (GV 20) was applied, three times per week and 3 months were considered as one session. Totally two sessions were performed. The menstruation condition, estradiol (E2), follicle-stimulating hormone (FSH) and scores of the clinical perimenopausal symptoms were taken as treatment outcomes.
RESULTSThe total effective rate was 86.7% (26/30) and the cured rate was 16.7% (5/30). The recovery rate of menstruation was 16.7% (5/30) and the regain rate of menstruation was 56.7% (17/30). After the treatment, the level of E2 was significantly increased from (45.41 +/- 18. 09) pmol/L to (59.07 +/- 24.21) pmol/L (P < 0.05), and the score of perimenopausal symptoms was obviously reduced from 14.28 +/- 8. 30 to 4.04 +/- 3.28 (P < 0.01). However, no statistical differences could be seen in FSH before and after treatment (P > 0.05).
CONCLUSIONAcupuncture has certain effect on improving menstruation and perimenopausal symptoms in POF patients, which is likely to he related with increasing the level of E2.

Calcium hydroxide (CH) is applied to improve disinfection of root canals in most root canal retreatment. This study aimed to analyze the CH removal efficacy using 7 different root preparing files (K file, pre-curved K file, EndoActivator, Ultrasonic file, pre-curved ultrasonic file, F file and needle irrigation alone) with apical transportation. Standardized models of curved canal with such apical transportation or not were set up before applying CH to root canal for 7 days. Seven techniques described above were used for its removal. Then the roots were disassembled and digital photos were taken. The ratio of residual CH in the overall canal surface was calculated using the image analyzer image pro plus 6.0. The data were analyzed using one-way ANOVA with post hoc Tukey test. Results revealed that CH was effectively removed (P<0.05) by using all 6 mechanical methods except irrigation alone. In curved root canals with apical transportation, EndoActivator, pre-curved ultrasonic file and F file were found to be more effective in removing CH than the other four file (P<0.001), while there was no significant difference among EndoActivator, pre-curved ultrasonic file and F file groups (P>0.05). The percentage of residual CH in the canal with apical transportation was higher than that in the canal without apical transportation (P<0.05). In conclusion, CH can be hardly removed completely. Canal with apical transportation will result in insufficient CH removal. EndoActivator, pre-curved ultrasonic file and F file are more effective in the curved root canal with apical transportation.

OBJECTIVETo explore the intervention of baicalin on signal transduction and activating transcription factor expression of ulcerative colitis (UC) patients.
METHODSRecruited were UC patients at Outpatient Department of Digestive Disease, Inpatient Department of Digestive Disease, Center for Digestive Endoscopy of College City Branch, Guangdong Provincial Hospital of Traditional Chinese Medicine, and Southern Hospital affiliated to Southern Medical University from June 2010 to January 2011. They were assigned to the UC group (33 cases) and the diarrhea-predominant irritable bowel syndrome (IBS-D) group (30 cases). Another 30 healthy subjects were recruited as a healthy control group. Peripheral blood mononuclear cells (PBMCs) in vitro intervened by different concentrations baicalin were taken from UC patients. IL23R gene expressions in vitro intervened by different concentrations baicalin were detected using Q-PCR. Expressions of signal transducer and activator of transcription 4 (STAT4) , STAT6, phosphorylated-STAT4 (p-STAT4), and p-STAT6 were detected using Western blot. Serum levels of IFN-γ, IL-4, IL-6, and IL-10 were measured by ELISA. Effects of different concentrations baicalin on expressions of PBMCs, and levels of IFN-γ, IL-4, IL-10 of UC patients were also detected.
RESULTSCompared with the negative control group, 40 µmol baicalin obviously decreased IL23R gene expression of UC patients (P <0. 01). Compared with the healthy control group and the IBS-D group, p-STAT4/STAT4 ratios increased, p-STAT6/STAT6 ratios decreased, levels of IFN-γ, IL-4, IL-10 all increased in the US group (all P <0. 05). Compared with the negative control, 5 and 10 µmol baicalin groups, 20 and 40 moL baicalin obviously decreased p-STAT4/STAT4 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously increased p-STAT6/STAT6 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously lowered levels of IFN-γ and IL-4, and elevated IL-10 levels (all P <0. 05).
CONCLUSION40 µmoL baicalin could in vitro inhibit p-STAT4/STAT4 ratios, adjust p-STAT6/STAT6 ratios and related cytokines, thereby balancing the immunity and relieving inflammatory reactions of UC.

OBJECTIVETo evaluate the predictive value of Holter ECG recordings for patients with moderate-severe obstructive sleep apnea and hypopnea syndrome (OSAHS).
METHODSHolter recordings was performed in 76 patients who were diagnosed OSAHS by polysomnography (PSG) within one month from Jan. 2008 to July 2009 in our hospital. Twenty-eight patients were identified as mild OSAHS (AHI < or = 20) and forty-eight patients were moderate-to-severe OSAHS (AHI > 20). The indexes of heart rate variability (HRV), total scores of thirteen sleep apnea risk indexes of Holter recordings and BMI were analyzed by bivariate Logistic regression analysis.
RESULTSClinical features (eg. Gender, age, complicated with hypertension, coronary heart disease, diabetes mellitus, hyperglycemia, and taken beta-blocker), total scores, the sum of thirteen sleep apnea risk scores collected by Holter recordings (5.64 + or - 2.33 vs. 6.42 + or - 2.22, respectively, P > 0.05) were similar between patients with mild OSAHS and moderate-to-severity OSAHS. VLF/Total Power > 70%, the difference of daytime/nighttime LF Power < -70 and BMI were independent predictors of moderate-to-severe OSAHS with OR 3.98 (1.087 - 14.596), 3.69 (1.106 - 12.285) and 1.28 (1.062 - 1.544), respectively (all P < 0.05).
CONCLUSIONSVLF/Total Power and the difference of daytime/nighttime LF Power and BMI could be used as screening parameters to recognize patients with moderate-to-severe OSAHS.

The objective of this work was to develop a valuable adsorbent for recovery of platinum by studying the properties of Pt4+ -adsorption with immobilized Citrobacter freudii XP05 biomass. Five methods for immobilization of Citrobacter freudii XP05 biomass were compared. The method with gelatin-alginate sodium as entrapment matrix was considered to be the optimal. Spherical and uniform beads were produced and the SEM micrograph indicated that the cell of strain XP08 were uniformly dispersed within the matrix. The adsorption of Pt4+ by immobilized XP05 biomass was affected with adsorptive time, pH value of the solution, immobilized biomass concentration, Pt4+ initial concentration The adsorption was a rapid process. The optimal pH value for Pt4+ adsorption was 1.5, and its adsorptive capacity increased linearly with increasing Pt4+ initial concentrations in the range of 50 - 250 mg/L. The experimental data could be fitted to Langmuir and Freundlich models of adsorption isotherm. The adsorptive capacity reached 35.2 mg/g under the conditions of 250 Pt4+ mg/L, 2.0 g/L immobilized biomass, pH 1.5 and 30 degrees C for 60 min. 98.7% of Pt4+ adsorbed on immobilized biomass could be desorbed with 0.5 mol HC1/L. The characteristics of dynamic adsorption and desorption of immobilized XP05 biomass in packed-bed reactor were investigated. The saturation uptake was 24.66 mg Pt4+ /g under the conditions of flow rate 1.2 mL/min, pH 1.5, 50 mg Pt4+/L and 1.85 g biomass(dry weight) . Adsorptive efficiency of Pt4 + by the immobilized XP05 biomass was above 78% for 4 cycles of adsorption and desorption. The recovery of platinum from waste platinum catalyst was studied. The adsorptive capacity was 20.94 mg Pt4+/g immobilized biomass under the conditions of 4.0 g/L immobilized XP05 biomass, 117.76 mg Pt4+/L and pH 1.5 for 60 min. The immobilized XP05 biomass is potentially applicable to the recovery of platinum from waste and wastewater containing platinum.

OBJECTIVETo observe the mechanism of the optimized traditional acupuncture prescription for accouchement on cervical ripening based on the molecular biology by observing related indices of cervical ripening in late-stage pregnant rats.
METHODSTwenty initial pregnant Wistar rats were randomly divided into an electroacupuncture (EA) group (n = 10) and a model group (n = 10), and other 10 non-pregnancy female rats with same lot were selected as a blank control group. EA group was treated with the optimized traditional acupuncture prescription for accouchement on the 20th day of pregnant, which performed EA at bilateral "Hegu" (LI 4) for 20 min and then at bilateral "Sanyinjiao" (SP 6) for 5 min with 2 Hz/50 Hz sparse-dense wave, while the other groups without acupuncture intervention. The contents of matrix metalloproteinase 9 (MMP-9) and interleukin 8 (IL-8) in cervix tissue were detected by ELISA method.
RESULTSCompared with the blank control group, the contents of MMP-9 and IL-8 in the model group were increased significantly (both P < 0.01). Compared with the model group, the contents of MMP-9 and IL-8 in the EA group were increased significantly (P < or = 0.05).
CONCLUSIONOptimized traditional acupuncture prescription for accouchement can increase the contents of MMP-9 and IL-8 in cervix tissue of late-stage pregnant rats so as to promote cervical ripening, and the mechanism of EA in promoting cervical ripening is explained from the perspective of molecular biology.

OBJECTIVETo explore the effect of composite salvia injection (CSI) on platelet parameters in children with anaphylactoid purpura (AP) and its clinical significance.
METHODSOne hundred and fifty children with AP were assigned to two groups, 80 in Group A and 70 in Group B. They were treated, respectively, with conventional therapy only or conventional therapy combined with CSI. Their platelet parameters, including blood platelet count (BPC), mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT) were determined at the acute stage and convalescent stage, respectively.
RESULTSAt the acute stage, the BPC in AP children of both groups was in the normal range, but significant abnormality was shown in the levels of MPV, PDW and PCT. As for comparisons of these parameters at the convalescent stage, significant difference between the two groups was also shown in terms of MPV, PDW and PCT (P<0.05 or P<0.01).
CONCLUSIONAlthough platelet shows no quantitative change in the pathogenic process of AP, important functional changes are surely existent. CSI could promote the normalization of platelet function.
