This paper was aimed to study the protective effects and related mechanisms of Zhen-Gan Xi-Feng (ZGXF) decoction containing serum on 6-OHDA-induced oxidative stress in PC12 cells.The ZGXF decoction containing rat serum with low-,medium-,and high-dose (8,16,or 32 g.kg-1) or blank serum was used to preprocess PC12 cells for 1 h,and cultured together with 100 μM 6-OHDA for 24 h.And then,cells were collected.The fluorescent probe 2',7'-dichlorofluorescin diacetate (DCFH-DA) and fluorescence microplate reader were used to detect the level of reactive oxygen species (ROS).Real-time quantitative PCR was used to analyze the mRNA expressions of nuclear factor erythroid 2-related factor 2 (Nrf2),Nfe2l2,heme oxygenase-1 (HO-1),glutamate-cysteine ligase catalytic subunit (GCLc),and GCL modulatory subunit (GCLm).The luciferase report gene system was used to detect the antioxidant response element (ARE) activation.The results showed that ZGXF decoction-containing serum inhibited the 6-OHDA-induced oxidative stress,upregulated the Nfe2l2,HO-1 and GCLc mRNA expressions in cells processed with 6-OHDA.However,it has no significant effect on GCLm mRNA expression.It was concluded that ZGXF decoction-containing serum had protective effects on 6-OHDA-induced oxidative stress in PC 12 cells.Its mechanism may be correlated with the upregulation on Nfe2l2 mRNA expression,which activated ARE and further induced its downstream gene of phase Ⅱ detoxifying enzyme,as well as the HO-1 and GCLc mRNA expressions of antioxidant enzyme gene.

The study aims to solve the instability problem of methylphenidate (MPH) in plasma, and establish a LC-MS/MS method for simultaneous determining of MPH in human plasma. The stabilities of MPH in different media were studied, and the degradation characteristics of MPH in these media were also investigated by HPLC and LC-MS/MS. To a 200 microL aliquot of freshly collected plasma sample, 10 microL 2% formic acid was added immediately to prevent the hydrolysis of MPH in human plasma samples. Chromatographic separation was performed on a Sapphire C18 column using the mobile phase of methanol - 5 mmol.L-1 ammonium acetate buffer solution containing 0.1% formic acid (46 : 54). MPH was quantified by tandem mass spectrometry operating in positive electrospray ionization mode with multiple reaction monitoring. The detection used the transitions of protonated molecules at m/z 234.2-->84.1 for MPH and m/z 260.3-->183.1 for propranolol (IS), separately. The intra- and inter-assay precisions were all below 5.0%. The accuracies were all in standard ranges. The linear calibration curve was obtained in the concentration range of 0.035-40 ng.mL-1. The methods fulfilled the demand. The method was used to determine the concentration of MPH in human plasma after a single dose of 36 mg MPH tablet to 6 healthy Chinese volunteers. The method is suitable for the precisely determination of MPH and for pharmacokinetic study of MPH in human plasma.

Water soluble extract (WSE) is an important index for the quality evaluation of Astragali Radix (AR). In this study, the WSE of the wild AR from Shanxi province (SX) and the cultivated AR from Gansu Province (GS) were compared. The WSEs of two types of AR were determined according to the appendix of Chinese pharmacopoeia. Then the WSEs were subjected to NMR analysis, and the obtained data were analyzed using HCA, PCA, OPLS-DA, microarray analysis, and Spearman rank analysis. In addition, the Pearson correlation of differential metabolites were also calculated. The results showed that the WSE content of GS-AR (37.80%) was higher than that of SX-AR (32.13%). The main constituent of WSE was sucrose, and other 18 compounds, including amino acids, organic acids, were also detected. Multivariate analysis revealed that SX-AR contained more choline, succinic acid, citric acid, glutamate, taurine and aspartate, while GS samples contained more sucrose, arginine and fumaric acid. In addition, the Pearson correlations between different metabolites of the two types of AR also showed apparent differences. The results suggested that the WSE of two types of AR differs not only in the content, but also in the chemical compositions. Thus, the cultivation way is important to the quality ofAR. This study supplied a new method for the comparison of extract of herbal drugs.

The conventional therapy for arteriosclerosis obliterans (ASO) is Western medicine. However, it has some adverse effects and does not respond to some patients, and it is also very expensive.

OBJECTIVE: To evaluate the effects of Xuefu Zhuyu Decoction (XFZYD) on functions of vascular endothelium in patients with unstable angina pectoris (UAP). METHODS: Fifty patients with UAP were randomly divided into two groups: XFZYD-treated group with 32 cases and control group with 18 cases. The patients in the control group were given regular therapy, while the patients in the XFZYD-treated group were given XFZYD additionally on the basis of regular therapy. All patients in both groups were treated for 8 weeks. Then the contents of serum endothelin (ET), nitric oxide (NO), soluble vascular cell adhesive molecule-1 (sVCAM-1) and soluble intercellular adhesion molecule-1 (sICAM-1) were examined by radioimmunoassay, enzymic method and enzyme-linked immunosorbent assay (ELISA) respectively. RESULTS: The total response rate in the XFZYD-treated group was 93.75%, which was significantly higher than 66.67% in the control group (P<0.05). The contents of serum ET, sVCAM-1 and sICAM-1 in the XFZYD-treated group were much lower than those in the control group (P<0.01), while the content of serum NO was obviously higher than that in the control group (P<0.01). CONCLUSION: XFZYD can improve the functions of vascular endothelium by lowering the levels of endothelium-derived contracting substances, enhancing the levels of endothelium-derived relaxing substances, and reducing the cell adhesions, and hence to raise the therapeutic effects on UAP.

Objective To investigate the renal expression of stem cell factor (SCF) in lupus nephritis (LN) and its correlation with disease activity and renal injury parameters. Methods Histochemical stain was used to examine all renal specimens (LN group n=34, chronic glomerulonephritis n=16, control group n=8). Hyhridization in situ and immunohistochemistry were used to detect the expression of SCF and infiltration of mast cells, macrophages , α-SMA (+) cells in renal tissues of the two groups. SPS software was used for tissue of the control group. However, they increased markedly in lupus nephritis and CGN (t=6.03～14.25, P< 0.01). But there was no significant difference between LN and CGN in SCF and mast cells in renal interstitium. Positive correlation was observed among the expression of SCF and α-SMA and the number of mast cells and macrophages (r=0.47～0.84, P<0.01) at their corresponding locations. The expression of SCF and ot-SMA and the number of macruphages were positively correlated with renal pathological active index, chronic index, albuminuria and the injury of renal interstitium (r=0.34～0.93, P<0.05 or 0.01); meanwhile, it was negatively correlated with Ccr(r=-0.39～0.61, P<0.01). There was significant correlation between SCF, macrophages and anti-dsDNA antibody, complement C3 level, SLE disease activity index (SLEDAI). The number of mast cells in renal interstitium was positively correlated with chronic indexes and the injury of renal interstitium (r=-0.86, r=0.93, P<0.01) and negatively correlated with Ccr (r=-0.56, P<0.01), but not correlated with active index and albuminuria (r=0.27, r=0.23, P>0.05). Conclusion The expression of SCF is widespread in kidney, and it is markedly eorrelated with various kinds of inflammatory cells, renal inherent cells, renal function, and urine protein levels. SCF may be an critical participant in the initiation and progression of renal injuries in human lupus nephritis.

Objective To compare the clinical effects of dydrogesterone and gestrinone on postoperative endometriosis and the rate of pregnancy in patients with infertility. Methods One hundred and fifty patients with postoperative endometriosis were enrolled in the current study who were hospitalized in fuzhou General Hospital of Nanjing Command from Jan. 2009 to Aug. 2013. They were randomly divided into dydrogesternne group(76 cases)and gestrenone groups(54 cases)based on progestogent treatment. The situation of pain symptoms improvement,the recurrence rate of 1 year,side effects and postoperative pregnancy rate were observed in order to evaluate the drug efficacy. Results There were a high rate of postoperative pain remission rate and a low recurrence rate of the two groups,and the difference was not significant( P ﹥0. 05 ). The main adverse reaction of patients in dydrogesterone group was breast pain and the incidence rate was 3. 9%( 3/76 ),while there was no breast pain in gestrinone group,and the difference was not significant( P =0. 140 ). The main adverse reaction of patients in gestrinone group was liver function damage and the incidence rate was 25. 9%(7/54),while the dydrogesterone group hadn't liver function damage,and the difference between two groups was significant( P =0. 000 ). The abnormal uterus bleeding incidence rate in dydrogesterone group was 15. 8%(12/76),higher than that of gestrinone group(13. 0%(7/54)),and the difference was significant(P=0. 038) . The serum carbohydrate antigen-125(CA-125)level in two groups were down to normal after operation,and still declined after drug treatment for 3 months. But there was no obvious change after 6 months. One year pregnancy rate of dydrogesterone pregnancy was 80%(24/30),higher than that of gestrinone group(48%,12/25),and the difference was significant( P =0. 038 ). Conclusion There is no significant difference in therapeutic effect between two groups. However,dydrogesterone therapy have no significant liver damage,and a higher postoperation pregnancy rate.

Objective: To compare the effects of different methods on the glucose treat-to-target time, glucose fluctuation, hypoglycemia and insulin doses in the type 2 diabetic patients treated by insulin bump, and to find the best method to make the glucose to reach the standand level safely, fast and effectively in the type 2 diabetic patients treated by insulin bump. Methods; Sixty hospitalized type 2 diabetic patients inadequatly controlled by premix insulin treatment were randomly divided into convention group (n=20), Bolus Wizard group (n=20), and Bolus Wizard combined with monitoring (combination) group (n-20) according to the random number grouping method. The insulin doses of the patients in convention group were adjusted according to the glucose monitoring of fingertip and the doctor' s experiences; the insulin doses of the patients in Bolus Wizard group were adjusted according to the Bolus Wizard software in insulin bump, and the glucose monitoring of fingertip; the insulin doses of the patients in combination group were adjusted according to the Bolus Wizard software combined with real time continuous glucose monitoring system (RTCGM). The level of fingertip glucose was tested. The standard deviation of blood glucose (SDBG) and largest amplitude of glycemic excursion (LAGE) were used to evaluate the glucose fluctuation of the patients in various groups. The treat-to-target time, glucose fluctuation, hypoglycemia and daily insulin doses of the patients in various groups were recorded. Results: Compared with convention group, the treat-to-target time of the patients in Bolus Wizard group was decreased (t= 2. 30, P<0. 05); compared with Bolus Wizard group, the treat-to-target time of the patients in combination group was decreased (t=3. 50, P< 0.05). On the 3rd day of treatment, compared with convention group, the SDBG and LAGE of the patients in Bolus Wizard group were decreased (tSDBC; = 3. 11, tLAGE = 2.54, P<0.05); compared with Bolus Wizard group, the LAGE of the patients in combination group was decreased (tlage = 2. 47, P<0. 05). There were no significant differences in the incidence of total hypoglycemia events (χ2 = 2. 192, P=0. 532), significant hypoglycemia events (χ2= 2.765, P=0. 322) and nocturnal hypoglycemia events (χ2 = 2.192, P=0. 532) among the patients in various groups; there were no significant differences in the average insulin dosage (F= 2. 102, P=0. 131), the non-basic insulin dosage (χ2 = 2.328, P=0. 107) and the percentage of non-basic insulin (χ2= 2.104, P=0. 131) among the patients in various groups. Conclusion: Bolus Wizard software combined with real-time dynamic RTCGM has better effect in the treatment of type 2 diabetes without increasing the risk of hypoglycemia and insulin dosage.
