Objective To observe the blood-enriching effects and mechanism of albiflorin and paeoniflorin on immunosuppressional model mice with blood deficiency pattern induced by cyclophospha-mide.Methods The mouse model with blood deficiency pattern induced by intraperitoneal injection of cyclophosphamide was treated with intragastrical administration of albiflorin and paeoniflorin at high dose of 30 mg/kg,low dose of 15 mg/kg.Then the peripheral hemogram,thymus gland index and spleen index,granulocyte-macrophage colony stimulating factor (GM-CSF),interleukin-3 (IL-3),interleukin-6 (IL-6),tumor necrosis factor α(TNF-α)and granulocyte colony-stimulating factor were detected. Results High dose albiflorin and high dose paeoniflorin could increase WBC count(P <0.01 )and thymus gland index (P <0.01,P <0.05),serum contents of GM-CSF and G-CSF (P <0.001,P <0.01),also serum content of IL-3 (P <0.01,P <0.05),and decrease the serum content of IL-6(P <0.05)and TNF-α(P <0.001,P <0.01 ).Conclusion The blood-enriching effects against blood-deficiency via regulating the immunological function,suggests that albiflorin and paeoniflorin be the main effective components extracted from White Peony Root (Radix Paeoniae Alba,Baishao)with the effects of nourishing blood and liver.

Objective To investigate the predictive value of labor progress angle(AOP),fetal head descent distance(HPD)and their change rates in the outcome of vaginal trial of cesarean scar uterus.Methods A total of 170 pregnant women who underwent vaginal trial production of scar ute-rus after cesarean section were selected as study subjects,and were divided into successful group and failed group based on the trial production outcomes.Advanced oxidation processes(AOP)and head-perineum distance(HPD)were measured by ultrasound during the active phase of the first stage of labor when the cervix dilated to 4 cm and at 1 hour after the cervix dilated to 4 cm,respectively.The AOP change rate and HPD change rate after 1 hour of progress were calculated.The receiver operating characteristic(ROC)curve was used to analyze the predictive efficacy of AOP,HPD and their change rates in the outcome of vaginal trial production of scar uterus after cesarean section.Delong test was used to compare the differences in area under curves(AUCs).Results Among 170 pregnant women with scarred uterus after cesarean section who were pregnant again,139 cases(success group)were succeed in transvaginal delivery,while 31 cases failed trial delivery,and transferred to cesarean section(failure group).The AOP of the successful group was significantly larger than that of the failed group when the cervix was opened to 4 cm,and the HPD was significantly shorter than that of the failure group(P＜0.05).The AOP change rate and the change rate of HPD of the suc-cessful group were significantly higher than that of the failed group when the cervix dilated to 4 cm and at 1 hour(P＜0.05).The AUC of AOP and HPD in predicting the outcome of vaginal trial de-livery of scar uterus after cesarean section were 0.846 and 0.812 respectively,and AUC predicted jointly by AOP and HPD showed no significant differences compared with AUC predicted separately(P＞0.05).The AUC of the change rate of AOP and HPD in predicting the outcome of vaginal trial delivery of scarred uterus after cesarean section was 0.899 and 0.852 respectively,and the com-bined prediction of AOP change rate and HPD change rate had a higher AUC value than the AUC predicted separately.Its AUC value was higher than that of AOP combined with HPD(P＜0.05).Conclusion The AOP,HPD and their change rates when the uterine orifice expands to 4 cm in the active phase of the first stage of labor have predictive value for the outcome of vaginal trial produc-tion of scarred uterus after cesarean section.

OBJECTIVE: To determine the prevalence and incidence of illness of two-week duration, and the factors influencing these, among residents 15 years and older in four counties of Hunan Province. METHODS: Data were sampled from four counties of Hunan Province for the Fourth National Health Service Survey. Incidence and two-week prevalence of disease were used to assess the health service needs of residents. A non-conditional, stepwise logistic regression was employed to explore the influencing factors. RESULTS: The two-week prevalence and incidence were 11.5% and 3.9%, respectively, in four counties of Hunan. The three leading diseases of two-week prevalence were: respiratory diseases, digestive diseases, and musculoskeletal diseases. Non-conditional stepwise logistic regression showed that urban residents had 0.64 times the risk of two-week illness compared with the rural residents (P< 0.05); residents in the 45-59 year age group and the 60+ year age group had 1.69 and 2.62 times the risk of two-week illness compared with residents in the 15-44 year age group, respectively (P<0.05). The widowed had 1.91 times the risk of prevalence of two-week illness contrasted to singles (P<0.05); the students had 0.29 times the risk of two-week illness contrasted to the workers (P<0.05); urban residents had 0.63 times the risk of two-week illness compared with the rural (P<0.05); the widowed had 2.37 times the risk of incidence of two-week illness compared with singles (P<0.05). CONCLUSION The majority of health service needs of residents of four counties is generated by three diseases: respiratory diseases, digestive diseases, and musculoskeletal diseases. Relatively, rural residents, the elderly, employed persons and the widowed have higher health service needs than others and deserve specific attention.
