AIM: To study the effect of natural killer(NK)-cells on graft-versus-host disease(GVHD), graft rejection, engraftment and reconstituting of hematopoiesis in mouse allogeneic bone marrow transplantation. METHODS: Lethally irradiated BALB/c(H-2 d) mice were transplanted with C57/6j(H-2 b) bone marrow containing donor peripheral T cells and/or NK cells. Recipients CD 34 + cell counts and the expression of H-2K b+ cell were detected by flow cytometry, peripheral white blood cell(WBC) was detected by auto-cytometry, and the recipients survival rates, GVHD, engraftment and hematopoiesis recovery were then observed. RESULTS: In the group of transplanted with NK cells infusion, the incidence of GVHD was evidently lessened, the survival rates, WBC and CD 34 + cell counts and the expression of H-2K b+ cell were significantly high than that without NK cells infusion. CONCLUSION: In mouse allogeneic bone marrow transplantation, alloreactivity NK cells prevent GVHD, reduce graft rejection, and promote engraftment and reconstituting of hematopoiesis. [

Objective:To evaluate the effect of emodin on acute rejection after orthotopic liver transplantation(OLT) in rats.Methods:The LEW→BN OLT models were established.A total of 45 rats were divided randomly and equally into 3 groups:group A was treated with normal saline at dose of 0.5 ml/d intraperitoneally from 1st day to 8th day after operation;Group B,CsA at dose of 10.0 mg?kg-1?d-1;Group C,emodin at dose of 50.0 mg?kg-1?d-1.8 days after operation,6 recipients of each groups were killed for confirming rejection-active index(RAI) and hepatocellular apoptosis index(AI) by observing the pathologic change of transplanted liver in recipients.The other recipients were raised for observing the survival time.Results:Respectively,the survival time(days) of group A,B,C was 9.50?1.64,21.57?2.15,21.29?2.21.The survival time of group B,C was significantly longer than that of group A(P0.05).Respectively,the RAI of group A,B,C was 7.67?0.9,5.17?0.40,5.83?0.75 and the AI of group A,B,C was 35.83?2.32,15.83?1.33,16.50?2.35.The RAI and AI of group B,C was significantly lower than that of group A(P0.05).Conclusion:Emodin can reduce the hepatocellular apoptosis and suppress the acute rejection after OLT in rats.

Objective:To observe clinical therapeutic effects of method for supplementing Qi,activating blood circulation and resolving phlegm and effects on vascular endothelial function and blood coagulation system in senile patient of hyperlipemia.Methods:96 senile patients of hyperlipemia were randomly divided into a treatment group(n=56)and a control group(n=40).The patients of the treatment group were treated by oral administration of Danshen Jueming Granules and the control group by oral administration of Xuezhikang Capsules.Blood lipids,vascular endothelial function,blood coagulation system and safety were observed.Results:After treatment,the treatment group in decrease of plasma total cholesterol(TC)and low density lipoprotein-cholesterol(LDL-C)was superior to the control group(P

Objective : To analyze the screening results of Mycobacterium tuberculosis (MTB) and HIV co-infections in Ningbo City from 2012 to 2020, so as to provide insights into improving the tuberculosis control strategy. Methods : Data pertaining to HIV antibody testing among tuberculosis patients, MTB testing among HIV/AIDS patients, treatment of patients with MTB and HIV co-infections and prognosis of anti-tuberculosis therapy were collected from the annual working reports for the management of MTB and HIV co-infections in Ningbo City from 2012 to 2020, and the screening, treatment and prognosis of MTB and HIV co-infections were analyzed. Results : A total of 35 385 newly identified tuberculosis patients were reported in Ningbo City from 2012 to 2020, and there were 5 854 cases receiving HIV testing. The annual mean percentage of HIV screening was 17.57%, and the HIV screening rate appeared a tendency towards a rise in Ningbo City from 2012 to 2020 (χ2trend=4 926.309, P<0.001). Eleven patients were tested positive for HIV, with an annual mean HIV positive rate of 0.19%. A total of 26 043 HIV/AIDS patients received MTB screening, with an annual mean screening rate of 95.78%, and the annual screening rate of MTB appeared a tendency towards a rise in Ningbo City from 2012 to 2020 (χ2trend=79.077, P<0.001). A total of 81 tuberculosis patients were detected, with an annual mean detection rate of 0.31%. Among the 92 patients with MTB and HIV co-infections, there were 81 patients receiving anti-tuberculosis and antiviral therapy simultaneously (88.04%), 8 cases receiving anti-tuberculosis therapy alone (8.70%), 2 cases receiving antiviral therapy alone (2.17%) and 1 case without therapy (1.09%). Among the 89 MTB and HIV co-infected patients receiving anti-tuberculosis therapy, 27 cases were cured (30.34%), 53 cases completing the course of treatment (59.55%) and 7 cases died. Conclusions The MTB screening rate among HIV/AIDS patients and the percentage of MTB and HIV co-infected patients with successful anti-tuberculosis treatment were high in Ningbo City from 2012 to 2020; however, the HIV screening rate should be improved among tuberculosis patients.

Objective To screen thyroid function among planned pregnant women in Chongqing, to guide prenatal and postnatal care. Methods Proportional multi-stage stratified cluster random sampling method was adopted to enroll 11 953 planned pregnant women for questionnaire, physical examination, and serum samples collection. Results The median TSH was 2. 04 mIU/ L, P25 = 1. 36 mIU/ L,P75 = 2. 99 mIU/ L. TSH levels being normal, higher, and lower than the reference were 91. 47% , 6. 20% , and 2. 33% , respectively. In Northeast Chongqing, the proportions of median TSH level and TSH level above the upper limit were higher than those in other regions(P<0. 05). With improved education, proportions of TSH above the upper limit and below the lower limit declined(P<0. 05). With the increase in body mass index, the proportion of those whose TSH was above the upper limit showed elevated trend(P<0. 05). In women with history of adverse pregnancy outcomes, their median TSH was higher than that in the control group, and those, whose TSH level exceeded the upper limit, yield higher results than those in the control group(P<0. 05). In women with higher fasting blood glucose The median TSH level was lower than that in normal blood glucose group( P<0. 05), with the fasting plasma glucose concentration and TSH negatively correlated(P<0. 05). Conclusion The abnormal rate of TSH level in planned pregnant women was 8. 53% in Chongqing. The abnormal rate varies by different regions, education levels, body mass indexes, and blood glucose levels. Previous history of adverse pregnancy outcomes was related to elevated TSH levels. It is necessary to take pre-pregnancy thyroid function screening investigation.
