The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.

Objective To investigate the association between genetic polymorphisms of ERCCl-C8092A and susceptibility to liver cancer, as well as the gene-environmental interaction on the etiology of liver cancer in Fuzhou. Methods A case-control study was conducted to collect the information on environmental exposure while genetic polymorphism of ERCC1 was analyzed by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. General relative risk regression models were further applied to fit the interaction between genetic polymorphisms of ERCC1-C8092A and the environmental factors of liver cancer. Results ERCC1-C8092A variant genotypes were associated with significant increasing risk of liver cancer adjusted odds ratio (OR= 3.789,95%CI:2.792-5.142 ), compared to the wild-type homozygote. Data from the analysis of interaction showed that genetic polymorphism of ERCC1-8092A appeared superadditive interaction with drinking pond-ditch or with hepatitis B, and super-multiplicative interaction with eating moldy food. Conclusion The point mutation in ERCC1-8092A was possibly susceptible to liver cancer, and related synergistically with other risk factors in hepatocelluar carcinogenesis in Fuzhou.

Objective To investigate burnout and stress level and their correlation of nurses at class two psychiatric hospital in Beijing.Methods Burnout Inventory ( MBI ) and work stress scale were used to survey 119 psychiatric nurses at two class two psychiatric hospitals in Beijing.Results Both burnout and stress sources of nurses with different general information showed no statistic difference (P ＞ 0.05).Psychiatric nurses'burnout scores were lower than the dimension of MBI norm ( P ＜0.01).Burnout and emotional exhaustion scores,total scores and the dimensions of nursing stress were significantly positively correlated (P ＜ 0.05 or P ＜ 0.01).The tendency to depersonification was significantly positively correlated with other four items except the workload and time allocation ( P ＜ 0.05 or P ＜ 0.01).Personal sense of achievement was only negatively significantly associated with management and interpersonal relationship ( r =- 0.323,P ＜ 0.01).Sources of work stress of psychiatric nurses in 5 dimensions from high to low is working environment and resources (2.43 ± 0.921),the nursing profession and work ( 2.42 ± 0.839 ),workload and time allocation ( 2.40 ± 0.892 ),patients care (2.37 ±0.673 ),management and interpersonal relationship ( 1.82 ± 0.708 ).Conclusions Hospital managers is recommended to take effective measures to reduce or eliminate sources of stress of nurses,emphasis on the training of coping with the working burnout,relieve the nurses working burnout,and enhance the caring quality.

Objective: To investigate the effect of moxibustion at Shenque (CV 8) on fatigue in rats with chronic exercise-induced exhaustion. Methods: Thirty male Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group and a moxibustion group, 10 rats in each group. Except rats in the blank group, the remaining rats were subjected to create long-term exhaustion models by repeated swimming. After successful modeling, rats in the moxibustion group received mild moxibustion at Shenque (CV 8) for 15 min, once every other day with a total of 10 times. Rats in the model group and the blank group did not receive moxibustion. At the end of the treatment, the exhausted times, and the body weight of rats before and after the experiment were compared among groups. The levels of blood malondialdehyde (MDA) and urea nitrogen (BUN), as well as the activities of aspartate transarninase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were also measured by the automatic biochemical analyzer, 24 h after the exhausting excise. Results: The 10th swimming time was significantly longer in the moxibustion group than that in the model group (P<0.01). The increase rate of the body weight was lower in the rats of the moxibustion group than that in the model group before the 7th and the 10th exhausting excise (P<0.05, P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the model group were higher than those in the blank group (all P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the moxibustion group were lower than those in the model group (P<0.01). Conclusion: Moxibustion at Shenque (CV 8) can decrease the serum levels of MDA and BUN, as well as activities of AST, ALT and LDH in the long-term fatigue rats, thus to improve the symptoms of fatigue.

BACKGROUNDHereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease characterized by recurrent epistaxis, mucocutaneous telangiectasia, and arteriovenous malformations. The efficacy of traditional treatments for HHT is very limited. The aim of this study was to investigate the therapeutic role of thalidomide in HHT patients and the effect in FLI-EGFP transgenic zebrafish model.

METHODSHHT was diagnosed according to Shovlin criteria. Five HHT patients were treated with thalidomide (100 mg/d). The Epistaxis Severity Score (ESS), telangiectasia spots, and hepatic computed tomography angiography (CTA) were used to assess the clinical efficacy of thalidomide. The Fli-EGFP zebrafish model was investigated for the effect of thalidomide on angiogenesis. Dynamic real-time polymerase chain reaction assay, ELISA and Western blotting from patient's peripheral blood mononuclear cells and plasma were used to detect the expression of transforming growth factor beta 3 (TGF-β3) messenger RNA (mRNA) and vascular endothelial growth factor (VEGF) protein before and after 6 months of thalidomide treatment.

RESULTSThe average ESS before and after thalidomide were 6.966 ± 3.093 and 1.799 ± 0.627, respectively (P = 0.009). The "telangiectatic spot" on the tongue almost vanished; CTA examination of case 2 indicated a smaller proximal hepatic artery and decreased or ceased hepatic artery collateral circulation. The Fli-EGFP zebrafish model manifested discontinuous vessel development and vascular occlusion (7 of 10 fishes), and the TGF-β3 mRNA expression of five patients was lower after thalidomide therapy. The plasma VEGF protein expression was down-regulated in HHT patients.

CONCLUSIONSThalidomide reverses telangiectasia and controls nosebleeds by down-regulating the expression of TGF-β3 and VEGF in HHT patients. It also leads to vascular remodeling in the zebrafish model.

BACKGROUND:Autologous platelet rich plasma and bone marrow mesenchymal stem cells have certain effects on bone repair,but there are rare reports on the clinical treatment of long shaft fracture bone nonunion using autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation.OBJECTIVE:To investigate the therapeutic effect of autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation on long shaft fracture bone nonunion.METHODS:Forty-seven patients with long shaft fracture bone nonunion were randomly divided into two groups:monotherapy group (n=22) and combination group (n=25).In the monotherapy group,autologous bone marrow mesenchymal stem cell transplantation was performed in the bone nonunion site.In the combination group,autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation was implemented in the bone nonunion site.Callus score,clinical healing time,local complications and limb function grade were recorded and compared between the two groups.RESULTS AND CONCLUSION:The healing properties and limb function in the combination group were significantly superior to those in the monotherapy group [healing time:(4.2±1.5) vs.(5.6±1.1) months,P ＜ 0.05;healing rate:92％ vs.86％,P ＜ 0.05;callus score:2.74±0.36 vs.2.32±0.53,P ＜ 0.05;limb function recovery rate:77％ vs.84％,P ＜ 0.05].Complications like local skin redness or infection were not found in the two groups.In conclusion,both of the two methods can promote bone healing,but autologous platelet rich plasma combined with bone marrow mesenchymal stem cell transplantation has a better clinical effect on bone healing.

Objective To explore the distribution of water with high level arsenic and prevalence of arsenism along Huai'he River and the surrounding area of Hong'ze lake in Huai'an of Jiangsu. Methods Wate rsamples were collected and tested in 2008 from 18 villages of 6 towns according to history data in 3 counties like Xuyi,Jinhu and Hongze. Samples having arsenic level higher than 0.05 mg/L were investigated by epidemiological method and the patients were diagnosed by Standard of Diagnosis for Endemic Arsenism. Results All 5199 water samples were determined,and 260 water samples were exceeding the national drinking water quality level (0.05 mg/L) in 3 counties,the rates of exceeding diagnosis were 5.6%(247/4454),0.7%(4/597),6.0%(9/148) respectively. Total detected rate of endemic arsenic disease was 5.94%(128/2155). The detected rates of age group of 0 ～ ,20 ～,30 ～ ,40 ～ ,50 ～ ,60 ～ ,70 ～ ,80 ～ were 2.86%(1/35),2.11%(2/95),1.26%(3/239),3.10%(16/516),5.53% (32/579),10.07%(41/407),11.84%(27/228),10.71%(6/56) respectively. The detected rate of male (9.10%,78/857) was higher than that of female(3.85%,50/1298,χ~2 = 25.46,P < 0.01). Conclusions Huai'he River and the surrounding areas of Hong'ze lake like Xuyi,Jinhu and Hongze are identified existing endemic arsenic disease area. The prevention of arsenism should be strengthened in these areas.

Growth suitability as assessment indicators for medicinal plants cultivation was proposed based on chemical quality determination and ecological factors analysis by Maxent and ArcGIS model. Notopterygium incisum, an endangered Chinese medicinal plant, was analyzed as a case, its potential distribution areas at different suitability grade and regionalization map were formulated based on growth suitability theory. The results showed that the most suitable habitats is Sichuan province, and more than 60% of the most suitable areawas located in the western Sichuan such as Aba and Ganzi prefectures for N. incisum. The results indicated that habitat altitude, average air temperature in September, and vegetation types were the dominant factors contributing to the grade of plant growth, precipitation and slope were the major factors contributing to notopterol accumulation in its underground parts, while isoimperatorin in its underground parts was negatively corelated with precipitation and slope of its habitat. However, slope as a factor influencing chemical components seemed to be a pseudo corelationship. Therefore, there were distinguishing differences between growth suitability and quality suitability for medicinal plants, which was helpful to further research and practice of cultivation regionalization, wild resource monitoring and large-scale cultivation of traditional Chinese medicine plants.
