ObjectiveTo evaluate the therapeutic effect ofHuangqi-Guizhi-Wuwu decoction in patients with diabetic peripheral neuropathy (DPN).MethodsA total of 78 patients with DNP were included and divided into a control group and a treatment group, with 39 in each group. The patients in the control group were administrated with appropriate exercise, control diet, hypoglycemics, mecobalamin and vitamin B1, those in the treatment group were receivedHuangqi-Guizhi-Wuwu decoction on the basis of the control group. The patients in both groups were treated for 8 weeks. The serum activities of superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase were determined by enzymatic-colorimetric method, and the serum malondialdehyde level was measured using colorimetric method. Sensory nerve conduction velocity (SCV) and motor nerve conduction velocity (MCV) were measured using an Electromyograph and Evoked Potential Equipment.ResultsAfter treatment, MCV (43.12 ± 4.1 m/svs. 40.27 ± 2.8 m/s;t=3.585,P<0.05)、SCV (41.51 ± 3.4 m/svs. 39.63 ± 3.5 m/s;t=2.406,P<0.05) in the treatment group were significantly increased than those in the control group. The serum activities of SOD (51.1 ± 6.6 U/mlvs. 47.6 ± 3.9 U/ml;t=2.851,P<0.01),GSH-Px (241.7 ± 36.1 U/mlvs. 213.9 ± 31.7 U/ml;t=3.614,P<0.01) in the treatment group were significantly increased than those in the control group. The total efficiency in the treatment group was significantly higher than that in the control group (87.2%vs. 69.2%;χ2=4.333,P=0.033).ConclusionsHuangqi-Guizhi-Wuwu decoction combined with conventional therapy could improve antioxidant capacity and control DPN progress in patients with DPN.

ObjectiveTo explore the roles of Toll-like receptor (TLR) 3,7 and 9 in the pathogenesis of pityriasis rosea.MethodsThis study recruited 40 patients with pityriasis rosea and 40 normal human controls.Reverse transcription-PCR was carried out to detect the expressions of TLR3,7 and 9 in peripheral blood lymphocytes of these subjects.ResultsThe mRNA expressions of TLR3,7 and 9 in peripheral blood lymphocytes were significantly higher in patients with pityriasis rosea than in the normal human controls (Z =4.239,3.745,2.658,all P ＜ 0.05).There was a positive correlation between the expression of TLR3 and TLR7(r =0.574,P ＜ 0.01 ) as well as between that of TLR3 and TLR9 (r =0.551,P ＜ 0.01 ) in the patients,while there was no correlation between TLR7 and TLR9 expression in the patients or between the expressions of TLR3,TLR7 and TLR9 in the controls.ConclusionVirus infection might be involved in the pathogenesis of pityriasis rosea via TLR pathways.

IgG functionalized Mn doped ZnS quantum dots ( IgG-QDs ) were fabricated via the amide condensation between the carboxy groups on the surface of Mn doped ZnS quantum dots and the amino groups on the surface of IgG. The IgG antibody functionalized Au nanoparticals were synthesized via the electrostatic interaction between the Au nanoparticals and IgG antibody. Based on the fluorescence resonance energy transfer effect between the IgG-QDs and the IgG antibody functionalized Au nanoparticals, the IgG-QDs could be applied for low background phosphorescent sensing of IgG with the linear range of 1-10 μg/mL and the limit of detection of 0. 45 μg/mL. The proposed method was successfully applied to detect IgG in human serum without the disturbance of the background fluorescence and scattered light.

Objective To investigate the clinical application of statins for secondary prevention and its efficacy in patients with ischemic stroke.Methods A total of 300 patients with ischemic stroke were divided into statins group (n=91) and control group (n=209) according to whether statins was received or not.Serum lipid parameters,liver and kidney function,carotid artery intimamedia thickness (IMT) and plaque area were compared between the two groups.Results In 209 patients not taking statins,68 cases (32.5％) were not advised by clinic doctor; 55 cases (27.8％)were reluctant to take statins in fear of adverse reactions; 77 cases (36.8％) discontinued stains when serum lipids were normal; 3 cases (1.4％) developed skin allergic reaction and the skin rash that disappeared after stains discontinuance; 3 cases (1.4％) had elevated liver enzyme levels and the enzyme levels were declined to normal after stains discontinuance.The levels of total cholesterol (TC),triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) were significantly lower in statin group than in control group [(4.93±0.45) mmol/L vs.(5.87±0.38) mmol/L,(1.68±0.61)mmol/L vs.(2.01±0.58) mmol/L,(2.49±0.57) mmol/L vs.(3.76±0.44) mmol/L,t=18.60,4.46,20.94,P=0.000,0.007,0.000,respectively].High density lipoprotein (HDL-C) level was significantly higher in stain group than in control group [(1.36±0.31) mmol/L vs.(1.03±0.25)mmol/L,t=9.75,P=0.001].There were no significant differences in liver and kidney function parameters such as alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase,serum total bilirubin,direct bilirubin,indirect bilirubin,glutamyl transferase,blood urea nitrogen and serum creatinine between the two groups (all P＞0.05).The carotid IMT and carotid atherosclerotic plaque area were significantly lower in stain group than in control group [(1.62 ± 0.23) mm vs.(1.74±0.31) mm,(0.57±0.12) cm2 vs.(0.65±0.18) cm2,t=3.32,3.88,P=0.008,0.002,respectively].Conclusions Most patients with ischemic stroke are still not taking statin for secondary prevention.Statins can improve the blood lipid levels and carotid arteriosclerosis status,and no obvious adverse reactions are observed.

Objective To investigate the clinical effect of McDonald cervical cerclage and the affecting factors. Methods Between January 2002 to December 2013 in Peking University First Hospital we performed McDonald cervical cerclage for 116 single pregnant women. They were defined as the successful group who deliveried the live babies after 28 weeks after the cerclage and the failure group who deliveried in the second trimester. According to the surgical indications they were divided into preventive cerclage group and therapeutic cerclage group. Then we analyzed the curative effect and the affecting factors in the groups. Results (1) In the 116 cases, 12 cases (10.3%) failed, and 104 cases (89.7%) succeeded. In the successful group, 37 cases (35.6%,37/104) deliveried pretermly and 67 cases (64.4%) deliveried termly. And there were 56 cases of vaginal delivery (53.8%), and 48 cases (46.2%) of cesarean section. (2) Among the 116 cases, 48 cases (41.4%) were included in prophylactic cerclage group, the gestational age was (16.3± 2.2) weeks, 68 (58.6%) cases were included in therapeutic group, the gestational age was (24.0±2.2) weeks. The operation time was (22±9) minutes in preventive group and (24±13) minutes in therapeutic group,there was no statistical difference between the two groups (P>0.05). Live-birth rate between preventive cerclage group and therapeutic cerclage group was no statistically significant difference (P>0.05). The term birth rate (72.9%, 35/48) in preventive group was higher than that in therapeutic group (47.1%, 32/68), the difference was statistically significant (P<0.01). Neonatal hospitalization rate was lower in preventive group (14.6%, 7/48) than therapeutic group (36.8%, 25/68) , the difference was statistically significant (P< 0.01). (3) In the failure group placental pathology was examed in 7 cases. The placental tissue showed a large number of neutrophils infiltrating in 6 cases (6/7). In the successful group, 27 pregnant women deliveried between 28 to 33+6 weeks (26.0%,27/104), 10 pregnant women deliveried between 34 to 36+6 weeks 10 cases (9.6%, 10/104), 67 cases deliveried after 37 weeks (64.4%, 67/104). A lot of factors including maternal age, the previous cervix operation history, perioperative application of progesterone, operation time and preoperative invasive procedure were compared between the successful group and the failure group. Only maternal age and preoperative invasive proedcure were statistically significant (P<0.05) and the others had no statistical significance (P>0.05). (4) There were 68 cases in the therapeutic group, 7 cases failed, and 61 cases succeeded;the preoperative cervical os in failure group [ (21 ± 20) mm] was wider than that in successful group [(14±5) mm], the difference was statistically significant (P<0.05);and preoperative vaginal ultrasound measurement of cervical canal length were (18 ± 8) mm versus (19 ± 10) mm, there was no statistically significant difference (P>0.05). Conclusions The McDonald cervical cerclage for cervical incompetence is a simple, safe and high successful rate of intervention measures. The term labor rate of prophylactic cervical cerclage was higher than that of the therapeutic cerclage. Older maternal age and preoperative invasive procedure may be the risk factors for cerclage. The infection may play an important factor leading to the failure of McDonald cervical cerclage.
