This study was aimed to explore the effect of total flavonoids and saponins from Huang-Qi Ge-Gen (HQGG) decoction on blood glucose (BG), serum lipid, interleukin-12 (IL-12) and interleukin-15 (IL-15) of liver in diabetes mellitus (DM) rats, in order to investigate their interactions in regulating DM processes. A total of 66 SD rats were randomly divided into 6 groups, which were the normal group, model group (A1B1), control group, total flavonoids group (A2B1), total saponins group (A1B2), and total flavonoids and saponins group (A2B2), with 11 rats in each group. Except the normal group, other groups were intraperitoneal injected with streptozotocin (STZ). And the experiment was according to 2×2 factorial design experiment scheme. The BG was determined before STZ injection and 7 days after the STZ injection. After 30 days, BG, serum lipid, IL-12 and IL-15 of liver were tested. Related indexes were calculated to the weighted composite score. Main and interactive effect of total flavonoids and saponins were studied according to the factorial design experiment scheme. The results showed that compared with the normal group, all indexes of model group showed statistical differences (P<0.05). Total flavonoids and saponins from HQGG decoction can effectively reduce BG, without any interactions between them. Both the total flavonoids and total saponins can reduce serum cholesterol (CHO), triglyceride (TG), liver IL-12 and IL-15. And there were interactive effects. The single use of herb achieved better effects than the combination. It was concluded that total flavonoids and saponins from HQGG decoction can reduce BG, CHO, TG, and liver IL-12 and IL-15 levels in rats. However, the regulation of total flavonoids and saponins on indexes mentioned above showed no additive effect.

Objective To evaluate the early diagnosis value of procalcitonin (PCT) in severe brain damage combined with pul‐monary infection .Methods The brain injury patients in the hospital from January to October 2014 were enrolled in the study and divided into infectious group whose infection had occurred within 5 days after admitting to hospital and non‐infectious group who had not suffered from infection .The blood samples of the patients were collected within 2 h and 3 days after admitting to hospital and detected for PCT concentration .The Early diagnosis value of PCT in brain damage combined with pulmonary infection was e‐valuated and compared with white blood cells (WBC) ,neutrophile granulocyte(N)and hypersensitive C‐reactive protein(hs‐CRP) . Results The incidence of pulmonary infection within 5 days of severe brain injury was 22 .9% (41/179) .There were statistically differences of PCT ,WBC ,N and hs‐CRP between infectious group and non‐infectious group(P< 0 .05) .The areas under curve (AUC) of PCT ,WBC ,N and hs‐CRP were 0 .83 ,0 .80 ,0 .78 and 0 .82 respectively .The combination of PCT+WBC+ hs‐CRP had the highest diagnostic value since its AUC was 0 .87 .PCT had a satisfied diagnostic veracity since it had good sensitivity ,specificity and positive predictive value in the diagnosis of brain damage combined with pulmonary infection .Conclusion PCT could be an ear‐ly diagnosis indicator in severe brain damage combined with pulmonary infection ,and the diagnostic veracity is higher when com‐bined with WBC and hs‐CRP .An antimicrobial treatment is recommended when PCT concentration of brain damage patient rises , especially when combined with WBC and hs‐CRP concentration elevating .

Objective To investigate the effect of human bone marrow mesenchymal stem cells (MSCs) on proliferation of CD8+ T lymphocytes and its mechanism. Methods MSCs were isolated and cultured then identified through many ways. The proliferative influence of MSCs on peripheral blood mononuclear cells (PBMCs) stimulated by PHA was investigated. The effect of MSCs on proliferation of CD8 + T lymphocytes induced by PHA was explored by flow cytometry. The possible mechanism of the inhibition effect of MSCs was investigated on the proliferation of CD8+ T cells stimulated by PHA with Transwell assay. Results MSCs were successfully harvested and cultured in vitro. MSCs suppressed the proliferation of CD8+ T cells stimulated by PHA when MSCs ∶ PBMCs ≥ 1 ∶ 5, which showed a dose-dependent manner. Strong proliferative inhibition of MSCs was presented on the CD8 + T cells induced by PHA in the group of Transwell (MSCs ∶ PBMCs = 1 ∶ 1) and the influence was similar to non-Transwell group. Conclusion MSCs can affect body immunity via suppressing the proliferation of CD8+ T cells.

Objective To investigate the effect of hosphocreatine therapy on the plasma cardiotrophin-1(CT-1) and N terminal probrain natriuretic (NT-proBNP) in elderly hypertensive patients with heart failure. Methods A total of 76 hy-pertensive patients with heart failure, aged 65 or over, were randomly divided into treatment group and control group (n=38 for each group). The control group received routine anti-heart failure treatment. The treatment group received conventional therapy plus creatine phosphate sodium for 2 weeks. The plasma levels of CT-1 and NT-proBNP were determined in two groups. The plasma CT-1 level was measured by a double antibody sandwich enzyme-linked immunosorbent assay (ELISA). The plasma level of NT-proBNP was tested by Rui Pu fluorescent dry quantitative analyzer. Results The plasma levels of CT-1 and NT-proBNP were significantly lower after treatment in two groups (P＜0.01). The plasma levels of CT-1 and NT-proBNP were significantly decreased in treatment group than those in control group (P＜0.05). The total effective rate was 89.47%in treatment group, which was significantly higher than that of control group (71.05%, P＜0.05). Symptoms of heart failure improved in one week (21 cases in treatment group/9 cases in control group) and in two weeks (13 cases in treatment group/18 cases in control group). Conclusion The conventional therapy plus creatine phosphate sodium can decrease the plasma CT-1 and NT-proBNP levels in elderly hypertensive patients with heart failure, which improves symptoms of heart failure in a shorter period of time.

[Objective]To observe the dynamic changes of serum LH levels in different GnRH-along protocols ,and investigate the relationship between GnRH-adosage and LH levels ,and compare the clinical outcomes among different GnRH-a long protocols.[Methods]In this retrospective study,1.0 mg,0.8 mg,0.375 mg long-acting and 0.1 mg/d,0.05 mg/d short-acting GnRH-a long protocols were included from January to June in 2015 at the Reproductive Medicine Center of the First Affiliated Hospital of Sun Yat-Sen University. Serum LH levels were evaluated from a total of 250 women at the four time points,on the day before gonadotropin stimulation(Gn0),the fourth day of Gn stimulation(Gn4),the seventh day of Gn stimulation(Gn7),and the HCG administration day(HCG day),then the relationship between serum LH levels and the dosage of GnRH-a were analyzed. The number of oocytes retrieved,fertilization rate,good quality embryos rate,blastocyst transferred rate,the number of transferred embryos,implantation rate and clinical pregnancy rate were also compared.[Results]Among the long-acting groups,LH levels in 0.375 mg group were higher than those in 1.0 mg and 0.8 mg groups at the four time points(P<0.05). Total Gn dose,duration of Gnstimualtion and HMG dosage of 1.0 mg protocol and 0.8 mg protocol were significantly higher than those of 0.375 mg group(P < 0.05). In addition,the implantation rate showed an increasing tendency when the level of LH increases(P>0.05). In short-acting groups,the LH levels in 0.05 mg/d protocol were significantly lower than those in the 0.1 mg/d group at Gn0,Gn7 and HCG day(P<0.05). Total Gn dose,du?ration of Gn stimulation and HMG dosage did not show significant difference between 0.05mg and 0.1mg group. What′s more,the im?plantation rate in 0.1 mg/d group was higher than in 0.05 mg/d group(P>0.05).[Conclusion]Among the long-acting groups,the smaller amount of GnRH-a was administrated ,the higher LH levels during ovarian stimulation and implantation rate the patients ob?tained. As to the short-acting groups,the LH level and implantation rate in 0.1 mg/d group is higher than those in 0.05 mg/d group.
