Objective To investigate the effect of electro-acupuncture (EA) on vascular permeability in patients undergoing open-heart surgery with CPB. Methods Thirty-two NYHA class Ⅰ or Ⅱ and ASA class Ⅱ or Ⅲ patients with BMI of 19-28 kg/m2 undergoing open heart surgery with CPB were randomly divided into 2 groups ( n = 16 each): Ⅰ control group and Ⅱ acupuncture group . The patients were premedicated with intramuscular phenobarbital 0.1 g, pethidine 50 mg and scopolamine 0.3 mg. Anesthesia was induced with midazolam, propofol, fentanyl and vecuronium and maintained with TCI of propofol and fentanyl in both groups. The patients were acupuncture points (neiguan, lieque, yunmen) were selected for stimulation with stimulator. Acupuncture stimulation was started from 30 min before anesthesia induction and continued until the end of operation. The level of sedation was monitored by BIS and maintained at 40-60 during operation. Urinary microalbumin concentration was used as a parameter of vascular permeability, and was measured before and at the end of operation. Blood samples were taken 24 h before and 24 h after operation for measurement of ALT, AST, total bilirubin, BUN and Cr. Results The two groups were comparable with respect to sex ratio, age, body weight, ASA physical status, and preoperative ejection fraction. There was no significant difference in renal and liver function between the 2 groups.Postoperative urinary microalbumin concentration was significantly lower in acupuncture group than in control group. Conclusion Acupuncture can reduce the effect of open heart surgery performed under CPB on vascular permeability.

OBJECTIVE:To study the enhancing effects of azone at different concentrations on percutaneous permeation of compound tinidazole gel and to find out the best concentration.METHODS:Using vertical Franz-type diffusion cell and dif?ferent concentrations of azone as enhancer,the concentrations of tinidazole,chloramphenicol and salicylic acid in permeation solution were measured by RP-HPLC,then cumulative permeation quantity(Q)was calculated.RESULTS&CONCLUSION:Azone at different concentrations could promote the permeability of3ingredients of compound tinidazole gel,and2%azone had the most obvious permeation-enhancing effect.

Objective To investigate the anatomical character and clinical application value of external malleolus periosteum bone flap pedicled with facia and external malleolus anterior artery. Methods Applied anatomy was studied with 10 adult corpse specimen after artery perfusion,observed the origin.trackway,and measured the external diameter and major vessel's length of external malleolus anterior artery,observed the composition of external malleolus artery net,and completed the performance in clinic in 10 patients and followed up for 6 months～6 years. Resultes The bone flap had abundant blood-supply,its pedicle was long enough for transfer,little injury to donor,the surgical procedure was easy to manipulate,and was used in clinic to treat talus fracture in 9 cases (fresh 5 and old 4) and old tibia fracture in 1 case,10 cases were involved with satisfactory outcome. Conclusion External malleolus periosteum bone flap pedicled with fascia and external malleolus anterior artery is a good new donor for the patients with fracture of talus or lower tibia,especially ununited case or osteonecrosis.

Severe combined immunodeficiency(SCID)is a kind of severe primary immunodeficiency disease.Patients often develop symptoms after birth, which is characterized by recurrent and life-threatening infection, sometimes accompanied by varying degrees of dysplasia.According to the classification proposed by the PID expert Committee of the International Union of Immunological Societies, SCID is clinically classified by the number of lymphocytes.Early screening and intervention of SCID is significant to improve the prognosis.With the promotion of TREC and other early screening methods, the detection rate of SCID has significantly improved, but the accurate detection rate in different ethnic groups still needs further explored.Hematopoietic stem cell transplantation is a traditional therapy for radical cure of SCID.And the safety of gene therapy for SCID has been gradually guaranteed with continuous improvement during recent years.This article will review the classification, early screening methods and treatment progress of SCID.

Objective To determine the safety and clinical value of secondary ERCP to a failed intubation procedure.Methods A total of 212 patients with difficult intubation during ERCP procedures were enrolled.Patients with failed conventional intubation accepted precut sphincterotomy.The operation stopped after one hour of effort.A secondary selective ERCP was performed at a appropriate time.The operation success rate and complication rate of first ERCP and secondary ERCP were compared.Results The success rate of first ERCP was 67.0％ (142/212),and the total success rate was 90.6％ (192/212).The total success rate is significantly higher than that of first ERCP operation(x2 =35.263,P ＜0.05).The complication rate of first ERCP,secondary ERCP and total complication rate was 8.96％ (19/212),4.29％ (3/70),10.38％ (22/212),respectively.Complication rates of total ERCP and secondary ERCP were not significantly different from the first ERCP (P ＞ 0.05).Conclusion It is safe and effective for patients with failed ERCP intubations after precut to receive a secondary ERCP at a appropriate time.

Objective To investigate the serum level of visfatin, C-reactive protein (CRP) and monocyte chemoattractant protein-1 (MCP-1) in patients with polycystic ovarian syndrome (PCOS), and provide the basis for understanding the pathogenesis of PCOS. Meth-ods 94 patients with PCOS and 100 healthy subjects were divided into 4 subgroups according to their body mass index(BMI), including obese PCOS subgroup(n = 52), non - obese PCOS subgroup (n = 42), obese healthy subject subgroup (n = 43) and non - obese healthy subject (n = 57). Serum visfatin, CRP, MCP-1, sex hormone levels and metabolic parameters were measured by enzyme-linked immu-nosorbent assay (ELISA), automatic chemistry analyzer or chemiluminescent immunoassay. Results Serum levels of testosterone (T), lu-teiizing hormone (LH) and prolactin (PRL) in the PCOS group were significantly higher than those in healthy subjects group(P <0.05～0.01), and follicle-stimulating hormone (FSH) levels were significantly decreased in PCOS group(P<0.01). Serum levels of Visfatin, CRP, MCP-1,fasting insulin(Fins) and insulin resistance homa model (HOMA-IR) in the obese or non - obese PCOS subgroup were signif-icantly increased than that in the obese or non - obese healthy subjects subgroup respectively (P<0.01). Pearson correlation analysis showed that the visfatin, CRP and MCP-1 levels were positively related to BMI, FINS and HOMA-IR(r=0.323～0.675, P<0.01). Par-tial correlation showed that serum visfatin levels were correlated with HOMA-IR(r=0.491, P<0.01), and serum MCP-1 levels were cor-related with LH (r=0.267, P<0.05) in the PCOS group. Conclusion The patients with PCOS had higher visfatin, CRP and MCP-1 lev-els, and visfatin levels were positively correlated with insulin resistance. Obesity were involved in the chronic inflammation course in patients with PCOS.

In-stent restenosis after stenting is a major problem to perplex the minimally invasive interventional treatment and development in atherosclerotic cardio-cerebrovascular diseases.Intravascular inflammatory response is one of the important causes for restenosis after stenting in which as represented by interleukins,the cytokines play complex and variable roles.This article reviews the effects of the expression levels of interleukins on vascular endothelial hyperplasia and the incidence of in-stent restenosis.
