OBJECTIVETo observe the therapeutic efficacy and safety of gonadotropin-releasing hormone agonist (GnRHa) combined Wenshen Xiaozheng Decoction (WXD) in auxiliary treating endometriosis after laparoscopy.

METHODSOne hundred and thirty-four endometriosis patients with confirmative pathological diagnosis were assigned to three groups depending on whether they would receive adjuvant therapy or Chinese medicine treatment, i.e., the control group, the observation 1 group, and the observation 2 group. The 22 patients in the control group received no adjuvant therapy after laparoscopy. The 42 patients in the observation 1 group were treated with GnRHa 3.6 mg by subcutaneous injection starting from the 1st day to the 5th day of menstruation, once per 28 days. The 70 patients in the observation 2 group were treated with GnRHa 3.6 mg by subcutaneous injection in combination with WXD starting from the 1st day to the 5th day of menstruation, once per 28 days. They also took WXD for 7 doses, one cycle per every 28 days. The treatment lasted for three to six months. Serum levels of estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and cancer antigen 125 (CA125), as well as clinical efficacy, and adverse drug reactions were observed before and after treatment.

RESULTSThere was statistical difference in serum levels of E2, FSH, or LH between the control group and the observation 1 and 2 groups (P < 0.05). There was no statistical difference in serum levels of E2, FSH, or LH between the observation 1 group and the observation 2 group (P > 0.05). There was statistical difference in the clinical efficiency among the 3 groups (P < 0.05). There was statistical difference in the pre-post difference of CA125 levels among the three groups (P < 0.01). Compared with the control group, there was no statistical difference in the pre-post difference of CA125 levels between the observation 1 group and the observation 2 group (P > 0.05). No obvious adverse reaction occurred during the treatment.

CONCLUSIONSGnRHa combined WXD showed confirmative clinical efficacy in treating endometriosis after laparoscopy. It also could lower serum levels of E2, FSH, and LH levels. So it was an ideal solution for treatment of endometriosis.

1.0?10~7 copies/mL. The HBsAg IHC staining positive cells could be observed in 6 placental tissues and 3 fetus' liver tissues,and HBcAg was also positive in 1 case of fetus' liver tissue.After co-incubating the tropho- blastic cells and HBV DNA positive serum in vitro,HBsAg expression and HBV DNA could be detected.Apoptosis of HBV-infected trophoblastic cells increased,which was demonstrated by in vivo and in vitro experiments and the apoptosis of placental cells was correlated with the cord blood HBV DNA level.The results of in vitro experiments showed that the apoptosis of trophoblastic cells increased with the elongation of infection time.After 6 months,1 of 12 newborns was positive for HBsAg,HBeAg and anti-HBc,6 was positive for anti-HBs.Conclusions The mechanism of HBV intra-uterine infection may be that HBV breaches the placental barrier and infects the fetus.The localization and replication of HBV in fetal tissues and organs are probably the important factors of chronic HBV infections in neonates.The apoptosis of trophoblastic cells may be the protective mecha- nism for the placental barrier to block the HBV intra-uterine transmission.

Objective To analyze monitoring results of iodized salt and distribution characteristics of problem areas with non-iodized salt in Gansu province during 2001 - 2009 and to provide a basis to develop countermeasures to iodine deficiency disorders. Methods According to the criterion of "The National Scheme of Iodized Salt Surveillance", two levels of monitoring were carried out on production and wholesale-level(during 2001 -2007) and household-level(during 2001 - 2009). Salt iodine was determined by direct titration method (GB/T13025.7-1999), and Sichuan salt or special salt was determined with an arbitration method. Criteria for qualified iodized salt was (35 ± 15)mg/kg(20 - 50 mg/kg), and for non-iodized salt was ＜ 5 mg/kg. Results During 2001 - 2007, a total of 4900 salt samples at production and wholesale-levels were examined, with a qualification rate of 97.80% (4792/4900). Non-iodized salt rates were all below 5% in Gansu province, consumption rate of qualified iodized salt was higher than 90% after 2003. During 2001 - 2009, cities(states) with non-iodized salt problems appeared 23 times, with Linxia accounting for 39.1%(9/23), Wuwei accounting for 21.7%(5/23). During 2001 -2009, counties(districts) with non-iodized salt problem appeared 123 times, including 68 times of ethnic minorities and state poverty counties, accounting for 55.3%(68/123). During 2001 - 2005 and 2006 - 2009, ethnic minorities and state poverty counties were accounting for 49.4%(44/89) and 70.6%(24/34) in counties with non-iodized salt problem. Conclusions The quality of iodized-salt at production and wholesale level is satisfactory in Gansu province, household consumption rate of qualified iodized salt have reached national standard for eliminating iodine deficiency disorders. But ethnic minorities and state poverty counties are main regions with non-iodized salt problem,these areas will be the key areas of prevention of iodine deficiency disorders in Gansu province in the future.

Inflammation is part of the immune response, and inflammation may also induce or exaggerate some diseases through production of pro-inflammatory cytokines. More evidence have shown that the individual level of cytokine production is affected by single nucleotide polymorphisms in cytokine genes. Furthermore, as several nutrients participate in DNA protection and stabilization, altering gene expression and individual phenotype, nutrition has important interaction with inflammation. The purpose of this review is to give a recent update informations on the interaction of single nucleotide polymorphisms, inflammation and nutrition.

OBJECTIVE This study aimed to optimize polysaccharides extraction from Urena lobata L.and investigate its antioxidant activity.METHODS The mathematical model was established by re-sponse surface method (RSM) based on the results of single factor experiments, using polysaccha-rides extraction rate as response value,and using the ratio of water to material,cellulase concentra-tion,extraction temperature and time as experimental factors,which was used to screen optimum poly-saccharide extraction conditions from Urena lobata L.. Antioxidant activity of polysaccharides was stud-ied by DPPH and ·OH free radical elimination method. RESULTS The optimum conditions obtained by RSM were as follows:the cellulase level was 10.8 g·L-1,extraction time duration was 72 min,the ra-tio of water to feedstock was 7 mL·g-1,extraction temperature was 43℃,the pH value was 5.0.Under the optimal conditions, there was a difference of less than 5％ between predicted extraction rate 13.37％ and experimental extraction rate 13.32％. The polysaccharide yield was most significantly af-fected by cellulase concentration,followed by extraction time,water to material ratio and extraction tem-perature.IC50of DPPH and·OH were 1.082 g·L-1and 3.202 mg·L-1,respectively.Antioxidant activity of sample polysaccharides was weaker than those of vitamin C. CONCLUSION The polysaccharide extraction process from Urena lobata L. by cellulase enzymolysis approach was obtained, which was convenient and feasible,and extracted polysaccharides had good free radical scavenging activity.

OBJECTIVETo establish osteoblast model, primary cilla model was removed by chloral hyrate, observe effects of osteoblast primary cilla moved on enhancing ALP staining and calcified nodules staining in electromagnetic field.

METHODSThree 3-day-old male SD rats weighed between 6 and 9 g were killed, cranial osteoblast was drawed and adherencing cultured respectively. Cells were subcultured and randomly divided into 4 groups until reach to fusion states. The four groups included chloral hydrate non-involved group (control group), 2 mM, 4 mM and 8 mM chloral hydrate group, and cultured in 37 °C, 5% CO2 incubator for 72 h. Morphology of primary cilla was observed by laser confocal scanning microscope, and incidence of osteoblast primary cilia was analyzed by Image-Pro Plus 6.0 software. Cells in the correct concentration group which can removed cillia most effectively were selected and divided into 3 groups, including control group (C), Electromagnetic fields group (EMFs), and EMFs with 4 mM chloral hydrate group. DMEM nutrient solution contained 10%FBS were added into three groups and cultured for 9 days and formation of ALP were observed by histochemical staining of alkaline phosphatase. After 12 days' cultivation, formation of mineralization nodes was observed by alizarin red staining.

RESULTSCompared with control group and 2mM chloral hydrate group,4 mM chloral hydrate group could effectively remove osteoblast primary cilla (P<0.01). Removal of osteoblast primary cilla could weaken the formation of ALP and mineralization nodes in osteoblast in EMFS. Compared with EMFs group, the area of ALP and mineralization nodes in EMFs with 4 mM chloral hydrate group were decreased obviously (P<0.01).

CONCLUSION4mM chloral hydrate could effectively remove osteoblast primary cilia. Primary cilla participate in EMFs promoting formation of ALP and mineralization nodes in osteoblast and provide new ideas for exploring mechanism of EMFs promoting osteoblast maturation and mineralization.
