Objective To explore the relapse,therapeutic effect,risk and prognostic factors of the pulmonary invasive fungal disease(IFD)in patients with a history of pulmonary IFD following allogeneic hematopoietic stem cell transplantation(allo-HSCT).Methods Fourteen patients with a history of pulmonary IFD received allo-HSCT between March 2005 and October 2006.Before transplantation,10 patients obtained complete remission(CR)and 4 partial remission(PR)after antifungal therapy.Antifungal prophylaxis was initiated on the first day of the conditioning therapy.Logistic regression models were used for multivariable analyses.Results The relapse rate of pulmonary IFD after allo-HSCT was 71.43%(10/14).Of 10 patients in CR,6 relapsed and all four patients in PR relapsed.Seven patients relapsed less than 3 months and 3 relapsed between four and six months after transplantation.Among the 10 patients with a history of IFD who relapsed after transplantation,9 patients received antifungal therapy,4 obtained CR,2 PR again and the other 3 didn't obtain remission.The effective rate of anti-fungal therapy was 66.67% and the pulmonary IFD-related mortality was 35.71%(5/14).There was no significant difference between amphotericin B,itraconazde and voriconazole for antifungal prophylaxis in patients with a history of pulmonary IFD(P=0.122).No risk and prognostic factors of the pulmonary IFD was identified by multivariable analyses.Conclusion Pulmonary was not an absolute contraindication for allo-HSCT,and patients with a history of pulmonary IFD had a higher relapse rate and transplant-related mortality after receiving allo-HSCT.

Objective To investigate the association of vitamin D receptor gene (Apa1,Bsm1,Taq1) polymorphisms with autoimmune liver diseases risk.Metiods Case control test documents were retrieved through Pubmed,Ovid,Medline,and Web of science databases,according to the inclusion and exclusion criteria included in this study.The design of experiments,the characteristics of the object of study,research results was excerpted,STATA version 12.0 software were used.The correlation intensity was demonstrated with odds ratio (OR) and 95％ confidence interval (CI).Results A total of 6 publications containing 9 studies (7 studies about primary biliary cirrhosis,2 studies about autoimmune hepatitis) published from January 2000 to February 2012 were identified and 844 cases and 1 522 controls were included.The combined results based on all studies showed that there was a statistically significant link between Apa 1 and autoimmune liver diseases (OR =0.85,95％ CI 0.74-0.96,P =0.058,for a vs.A; OR =0.75,95％ CI 0.58-0.97,P =0.212,for aa vs.AA;OR =0.78,95％ CI 0.63-0.98,P =0.235,for Aa vs.AA; OR =0.77,95％ CI 0.63-0.94,P =0.231,for Aa/aa vs.AA),while the Bsm 1 and Taq 1 didn' t show the association with autoimmune liver diseases.Conclusion The current meta-analysis shows that Apal may be a low-penetrant risk factor for autoimmune liver diseases.Bsm1 and Taq1 don't show the association with autoimmune liver diseases.

OBJECTIVE:To compare clinical efficacy of Xiaoshi lidan capsules and Ursodeoxycholic acid capsules in the treat-ment of chronic cholesterol gallstone cholecystitis. METHODS:120 patients with chronic cholesterol gallstone cholecystitis in our hospital were selected and divided into observation group and control group according to random number table,with 60 cases in each group. Observation group was given Xiaoshi lidan capsules 1.2 g,po,tid(after the meal);control group was given Ursodeoxycholic acid capsules 250 mg,po,qd(after dinner). Both group received treatment for 6 months. Effective rate of litholysis were observed in 2 groups as well as abdominal pain score [PRI,VAS score,present pain intensity(PPI)],the thickness of gallbladder wall before and after treatment. Clinical efficacy and the occurrence of ADR were compared between 2 groups during treatment. RESULTS:3 pa-tients withdrew from the observation group and 1 patient withdrew from the control group. Before treatment,there was no statistical significance in PRI,VAS score,PPI and the thickness of gallbladder wall between 2 groups(P>0.05). After treatment,above index-es of 2 groups were decreased significantly,while PRI,VAS score and PPI in observation group was significantly lower than in con-trol group,with statistical significance (P<0.05). The effective rate of litholysis (64.91%) in observation group was significantly lower than in control group (79.67%),with statistical significance (P<0.05). Total effective rate of observation group (57.89%) was slightly higher than that of control group(54.24%),without statistical significance(P>0.05). There was no statistical signifi-cance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Xiaoshi lidan capsules are similar to Ursodeoxycholic acid capsules in clinical efficacy for chronic cholesterol gallstone cholecystitis with good safety,and can be used as optional drug ex-cept for chronic cholesterol gallstone cholecystitis.

Objective To observe the protective effect of anthocyanin on irradiation induced bone marrow c-kit positive cell injury, and further explore its possible mechanism. Methods Mouse bone marrow c-kit positive cells were collected by cell sorting method. There were 2 groups: control group and anthocyanin group, which were sub-divided into three groups and received 0 Gy, 1 Gy and 4 Gy irradiation respectively. The control group was added 700μL cell suspension and an equal volume of serum-free hematopoietic stem/progenitor cell culture medium. The 2 × 10-5 mol/L anthocyanin was co-cultured with mouse bone marrow c-kit positive cells of anthocyanin group half an hour before irradiation exposure, then cells were cultured for 18 hours under the conventional culture conditions (37℃,5%CO2). Mouse c-kit positive cell viability was measured by bioluminescence, and which was reflected by relative light units (RLU). The ability of colony-forming units was reflected by CFU-GM. The reactive oxygen species (ROS) level and mean fluorescence intensity (MFI) ofγ-H2AX were detected by flow cytometry. Results Compared to un-irradiated control group, the cell viability and the number of CFU-GM were decreased significantly, while the ROS level and MFI ofγ-H2AX were increased in c-kit positive cells irradiated with 1 Gy and 4 Gy (P<0.05). Compared to 1 Gy and 4 Gy irradiation groups, c-kit positive cell viability and the number of CFU-GM were increased, the ROS level and MFI of γ-H2AX were decreased in anthocyanin group (P < 0.05). Conclusion Anthocyanin exhibits a promising protective effect on radiation-induced bone marrow c-kit positive cell injury, which may be related to the alleviating ROS and DNA damage in bone marrow cells.

Abstact: Objective To investigate the diagnostic value of endoscopic sphineter Oddi manometry (SOM) in patients with recurring abdominal pain and observe the value of endoscopic sphincterotomy (EST) in treatment of patients with sphincter of Oddi dysfunction (SOD).MethodsClinical data of 30 patients with chronic abdominal pain after cholecystectomy who were suspected SOD from 2012 October to 2014 September were collected and retrospectively analyzed. These patients received SOM in ERCP examination and the observation of Oddi sphincter basal pressure, contraction amplitude, frequency and mode of transmission were carried out. The EST were carried out in patients with basal pressure of Oddi sphincter higher than 40.0 mmHg or higher than 30.0 mmHg, and the presence of serum amylase, lipase, ALT, AST, AKP increased more than 2 times of the normal value and (or) of common bile duct, pancreatic duct widening.ResultThe SOM of all the 30 patients were all abnormal. The basal pressure of Oddi sphincter, the contraction amplitude, the contraction frequency and the reverse shrinkage were (36.6 ± 21.1) mmHg, (210.6 ± 25.7) mmHg, (10.1 ± 3.1) times/min and (55.0 ± 8.0)%. All the patients were treated with EST, of which 27 cases (90.0%) received good results.Conclusion SOM is helpful in evaluation of Oddisphincter function, it is of great value in diagnosis of SOD. EST treatment obtained satisfactory effect in patients with elevated basal pressure of Oddi sphincter.

Objective To investigate the protective effect of hydrogen-rich water (HRW) on radiation-induced hematopoietic stem and progenitor cells (HSPCs) injury.Methods Totally 32 C57BL/6 mice were randomly divided into four groups with 8 mice in each group,including control,HRW,radiation and radiation + HRW.Mice in HRW and radiation + HRW groups received 0.5 ml hydrogen-rich water per day by intragastric administration 5 min before irradiation until 7 d post-irradiation.Mice in other groups received 0.5 ml distilled water.Mice in radiation and radiation + HRW group were irradiated with 2 Gy of total body irradiation.Bone marrow cells were isolated at 15 d post-irradiation,and LSK cells were examined for the percentage of hematopoietic stem and progenitor cells,the ability of colony formation and reconstitution,reactive oxygen species (ROS) levels and cell apoptosis.Results Compared with radiation group,the percentages of hematopoietic progenitor cells and LSK cells,colony number of bone marrow cells were significantly increased in radiation + HRW group (t =-4.935,-7.898,5.488,P ＜ 0.05).An elevation of donor chimerism was also found in recipient mice administered HRW after competitive bone marrow transplantation (t =-12.769,P ＜ 0.05).Compared with radiation group,the ROS levels and cell apoptosis in LSK cells were significantly decreased (t =4.380,3.954,P ＜ 0.05).Conclusions Hydrogen-rich water exhibited a protective effect on radiation-induced HSPCs injury.

Objective To investigate the protective effect of theaflavins on thymus injury caused by total body irradiation (TBI).Methods Twenty-five C57BL/6 mice were randomly divided into 5 groups:control group,4 Gy TBI group,4 Gy TBI + 25 mg/kg theaflavins group,4 Gy TBI + 50 mg/kg theaflavins group and 4 Gy TBI + 100 mg/kg theaflavins group.Thymus index and total number of thymocytes were detected at the 14th d post-irradiation to determine the optimal dose of theaflavins.According to this optimal dose,32 C57BL/6 mice were randomly divided into 4 groups:control group,theaflavins group,4 Gy TBI group and 4 Gy TBI + theaflavins group.Thymus histomorphology,CD4CD8 T cell subsets,and reactive oxygen species (ROS) in thymocytes were examined at the 14th d post-irradiation.Results The irradiated thymus exhibited decreased thymus index and total number of thymocytes (P ＜ 0.05),aberrant histomorphology and T cell subsets (P ＜ 0.05),and increased ROS level in thymocytes (P ＜ 0.05).Compared with 4 Gy TBI group,the thymus index and total number of thymocytes were significantly increased in 4 Gy TBI + 50 mg/kg theaflavins group (P ＜ 0.05).The total number of thymocytes was significantly higher in 4 Gy TBI + 50 mg/kg theaflavins group than that in 4 Gy TBI + 25 mg/kg theaflavins group (P ＜ 0.05).Therefore,50 mg/kg theaflavins was chosen as the optimal dose for subsequent experiments.Moreover,the aberrant histomorphology of irradiated thymus was alleviated by theaflavins.A decline in the percentage of CD4-CD8-T cells and an elevation of CD4+CD8-and CD4+CD8+ T cells were found in irradiated mice administered with theaflavins (P ＜ 0.05).Compared with 4 Gy TBI group,the ROS level was significantly decreased in 4 Gy TBI + theaflavins group (P ＜ 0.05).Conclusion Theaflavins exhibits a protective effect on radiation-induced thymus injury.

With the rapid economic growth and social development in the BRICS countries, the role of devel-opment assistance for health is becoming more and more significant. This paper describes the scales, recipient coun-tries, mechanisms and characteristics and management systems of development assistance for health in BRICS coun-tries. The paper suggests that a) it is necessary to set up a centralized international aid management agency;b) the mode of development assistance for health must be optimized;c) the scale of development assistance for health shall be increased ( over time);d) each BRIC country should use its own comparative advantages and development experi-ence to carry out development assistance for health while strengthening the cooperative power among the BRICS coun-tries;e) development assistance for health data should be more transparent and open;f) the evaluation of develop-ment assistance for health must be established and perfected.

Since the establishment of the People’s Republic of China, the development of China’s official de-velopment assistance for health has been going through three phases. To date, it has developed in many forms, inclu-ding the dispatch of medical team and the construction of health facilities. Since the market reforms, the global con-text together with the domestic socioeconomic foundations have changed; the impact of China’s relatively simple and segmented development assistance for health on the development of health systems in developing countries is limited;the effectiveness of assistance has been watered-down due to segmentation and vague management and accountability systems, as well as the lack of an overarching strategy;China’s health institutions, techniques and products suffer va-rious obstacles in their transfer to other countries where rules are dominated by western countries;compared with the increasing and multiple demands of development assistance for health from developing countries, the capacities of co-operation need to be further developed. As the paper suggests, use the “new major-country” and “new morality-in-terest” and“human oriented” concepts, as well as the ideology of“aid in order to develop, develop in order to coop-erate, so as to develop hand-in-hand” to guide China’s development assistance for health;innovate stereo-aid models to adapt to the changed foreign and domestic socioeconomic context; reform the development assistance for health management system and define rights and obligations appropriately;strengthen coordination and information sharing;link development assistance for health with global health governance to promote a maximized spillover effect;mobilize the civil society with strengthened guidance and supervision.
