Objective To investigate an effective method of autologous arteriovenous fistula formation for the elderly uremic patients with diabetic nephropathy.Methods The nest in the elbow above the median cubital vein at the curved incision 1-2 cm,inline high Fistula,namely arm cephalic vein and brachial artery bifurcation of the upper portion of the distal radioulnar side anastomosis in 20 cases over 75 years elderly uremic patients with diabetic nephropathy.And compared the effect of 16 cases of patients with similar conventional fistula.Results Twenty cases over 75 years elderly uremic patients with diabetic nephropathy were successful in all high dynamic fistula intravenous,blood flow was (1 007±131) ml/m,the immediate opening rate of 16 patients similar to conventional instant fistula was 12.5％,and a year after the opening rate was 6.25％ Conclusion High fistula are more easy to shape conventional,easy mature,full blood flow characteristics comparing with commom fistula,so elderly uremic patients with diabetic nephropathy fistula making difficult situation has been effectively improved.

The peptidyl prolyl cis/trans isomerase Pin1 specifically binds phosphorylated Ser/Thr-Pro protein motifs and catalyzes the cis/trans isomerization of the peptide bond,changes the conformation and influences the stability and activity of the substrates.To date,a subset of proteins has been identified as substrates for Pin1.Pin1 interacts with its substrates and plays crucial roles in cell cycle,neural pathology and immune response.Accumulating studies have revealed that Pin1 isomerase activity is regulated by its post-translational modifications,including phosphorylation and oxidation.Over-expression or regulative imbalance of Pin1 plays an important role in the pathogenesis and therapeutics of human diseases such as cancer and AD.

Objective By X-ray measurement of metacarpal and phalange bones in the right hand of adult patients with Kaschin-Beck disease in Qinghai Province,to provide anatomic data and information for clinic diagnosis of the disease and application of hand surgery.Methods Fifty-four cases of adult patients with Kaschin-Beck disease,who came from Guide County and Xinghai County in Hainan Prefecture,Qinghai Province,were selected as investigation subjects,then their right hand X-ray film were taken,metacarpal and phalange bones were measured by electronic digital vernier caliper.All data were analyzed with SPSS 19.0.Results The axis length of the metacarpal bones was in the order of:the 2nd metacarpal ＞ 3rd metacarpal ＞ 4th metacarpal ＞ 5th metacarpal ＞ first metacarpal.The axis length of proximal phalange bones was in the order of:the middle finger proximal ＞ ring finger proximal ＞ index finger proximal ＞ little finger proximal ＞ proximal thumb,while the middle,distal phalanx axis length varied greatly.The length of metacarpal and phalange bones of all male was longer than that of female(all P ＜ 0.01).The width of the metacarpal bones was in the order of:the 2nd metacarpal ＞ 3rd metacarpal ＞ 5th metacarpal ＞ 4th metacarpal.The width of the 2nd-5th metacarpal of male and female was (8.57 ± 0.90),(8.25 ± 0.80),(6.84 ± 0.69),(7.70 ± 0.77)mm and (7.40 ± 0.74),(7.36 ± 0.70),(6.00 ± 0.57),(6.62 ± 0.65)mm,respectively,the differences were significant(t =5.24,4.32,4.85,5.55,all P ＜ 0.01).The matacarpal bone index of female[(8.23 ± 0.90)mm] was significantly larger than that of male[(7.61 ± 0.76)mm,t =2.73,P ＜ 0.01].Conclusion X-ray measurement of hand may provide reference information for diagnosis of Kaschin-Beck disease and determination of metacarpal and phalange length in hand surgery.

Objective By investigating newly diagnosed Kashin-beck disease,to understand distribution range,epidemic intensity and prevalence trend of Kashin-Beck disease(KBD)in Xinghai County.Method According to monitoring method on national KBD,we carried on epidemical investigation,clinical examination and X-ray photograph on school children aged 7-13 years in 6 villages from 4 towns in Xinghai County,and hair,grain,water and soil were sampled to detect selenium content using naphthalene fluorescence.Resuit Three hundred and seventy.three school children aged 7-13 years underwent the clinical examination,the prevalence rate was 12.06%(45/373);347 school children were went on X-ray,the detection rate of X-ray was 21.61%(75/347).The selenium content was the lowest in Quanqu Village,Ziketan Town,which were(77.70±42.04),(7.44±6.93)μg/kg respectively;the selenium content Was highest in Cainaihai Village,Qushian Town,which were(103.88±58.57),(29.58±24.11)μg/kg respectively;level of in internal and external environment in 4 KBD region were all low.Conclusion These four region are new KBD region.The prevalence state of KBD is serious,pathogenetic factor of Kashin-Beck disease is very active.

[Objective] To discuss the reasonable treatment and skil of gal bladder calculus.[Method] Select 81 cases of such patients, take their clinical data as examples for analysis foundation;and choose relative documents for evidence of theoretic analysis.[Result] 77 cases were successively operated of laparo-scope, 3 transferred for laparotomy owing to difficult anatomy of Colot triangle, 1 made probe of choledoch because of choledocholithiasis;compared with documents results, the incision length, bleeding, operaiotn time, in-hospital time and complications of laparoscope operation, transferred laparotomy in the study were similar to relative documentary reports, the differences had no statistical meaning;the intranperative bleeding, operation period, in-hopital time, complications were better than documents, the differences had statistical meaning. [Conclusion] The correct pre-operation evaluation of disease condition, operation chance and methods selection, 3 operation points were the key of successful operaiton.

Objective To determine the relationship between blood biochemical metabolites and benign prostatic hyperplasia (BPH).Methods From Jan.2008 to Oct.2010,the medical records of 73 BPH patients diagnosed by postoperative histopathology were retrospectively studied.The age of patients ranged from 55 to 86 years.The average patient age was 70 years.Of the 73 cases,65 cases were not taking medications which could have an impact on metabolic levels of serum glucose and lipoprotein.Three months prior to operation,the patients were placed in a group to analyze the correlation between the total volume of the prostate (TP),prostate average annual growth rate and biochemical metabolites including serum glucose,high-density lipoprotein cholesterol (HDL-c) and prostate specific antigen (PSA).To compare the changes of prostate volume,prostate annual growth rate and PSA,the 73 cases were divided into two groups; patients with metabolic syndrome (MS) and those without MS.Results Of the 65 BPH patients,the mean of TP and prostate annual growth rate were (58.76 ± 25.96) ml and (1.32 ± 0.89) ml,serum glucose was (4.99 ± 0.73) mmol/L,HDL-c was (1.36 ± 0.39) mmol/L,and PSA was (5.99 ±8.30) μg/L.Stratified with prostate volume,patient's serum glucose,prostate annual growth rate and PSA levels increased with the increased TP (F =4.63,P =0.0060; F =62.98,P =0.0001 ; F =4.83,P =0.0044).On the other hand.HDL-c decreased with the increased TP (F =5.32,P =0.0025).There was a positive relationship between TP and serum glucose (r =0.48,P =0.0005).There was a negative correlation between TP and HDL-c (r =-0.26,P =0.0353).Of the 73 patients,20 cases had MS.The MS group had PSA levels (6.52 ± 5.28) μg/L,TP (79.41 ± 38.24) ml and prostate annual growth rate (1.86 ± 1.14) ml.These levels were higher than the 53 cases without MS.The group without MS had PSA levels (3.95 ± 3.77) μg/L,TP (54.98 ± 20.94) ml and prostate annual growth rate (1.23 ± 0.80) ml (t=2.29,P=0.0253; t=2.65,P=0.0147; t=2.22,P=0.0360).Conclusions PSAlevels,TP and prostate annual growth rate in BPH patients are related with blood biochemical metabolites.Both serum glucose and HDL-c affect prostate volume.BPH patients with MS have a remarkable clinical progression.
