Objective To explore the incidence,distribution and the risk factors of intracranial and extracranial artery stenosis in patients with ischemic cerebrovascular disease(ICVD)in Uygur and Han.Methods Both 165 Han and 108 Uygur patients of ICVD were detected by using DSA.The level of serum glucose and lipidemia were measured.Statistical analysis was used to evaluate the incidence,distribution and risk fators of intracranial and extracranial artery stenosis in Han and Uygur groups.Results 103(62.4%) cases in Han group and 70(64.8%)cases in Uygur group existed intracranial and extracranial artery stenosis,but there was no significantly difference between the two groups.There was no significantly difference in the distribution of cerebral arterial stenosis between Han and Uygur groups.In Han group,age,hypertension,smoking and low HDL were related to cerebral arterial stenosis(P

Objective To study the efficacy of antibiotic prophylaxis in old patients with negative urine cultures,who were submitted to transurethral prostate resection(TURP).Methods One hundred and twenty old benign prostatic hyperplasia(BPH) patients with sterile urine were divided into two groups(60 patients in each group) randomly.Antibiotic group received empirical venous antibiotics 4 days postoperative.Control group received 5% glucose saline as placebo.Their postoperative infection-associated parameters were compared.Results There were no significant differences between two groups in bacteriuria and infection-associated complications at the 28th day postoperatively.The ratio of bacteriuria in antibiotic group decreased significantly at postoperative at the 4th day when compared with that of control group.The bacteriuria at postoperative at the 4th day had no specific correlation with the long-term bacteriuria,the clinical observation of bacteremia and urinal tract infection,or the culture of prostatic tissue chip.Conclusions Antibiotic prophylaxis reduces the early postoperative bacteriuria for old patients with sterile urine before TURP,but its effectiveness for postoperative infectious complications is debatable.The antibiotics according to empirical validity are not specifically sensitive to the bacteria from various sources.

OBJECTIVE:To explore the safety and effects of liver function in patients with liver cirrhosis following virus B hepatitis(called“hepatitis B”for short)on drug half-life and analgesic effect of target controlled infusion of remifentanil. METH-ODS:100 patients with liver cirrhosis following hepatitis B underwent liver and gallbladder surgery under selective general anesthe-sia were collected from our hospital and divided into group A(mild abnormal liver function)and group B(severe abnormal liver function,3 cases withdrew from the test and 47 cases completed the test),with 50 cases in each group,according to Child-Pugh grading of liver function. Both group were given phenobarbital sodium 0.1 g+scopolamine 0.3 mg intramuscularly 0.5 h before oper-ation;midazolam 0.04 mg/kg+propofol 1.5 mg/kg+atracurium 0.6 mg/kg intravenously;target controlled infusion of Remifentanil hydrochloride for injection during operation with 0.125-0.250 μg/(kg·min). The distribution half-life and the elimination half-life of remifentanil were determined, and temperature pain perception threshold (tPDT) and electrical pain perception threshold (ePDT) were measured immediately after the operation;the occurrence of ADR was observed. RESULTS:The distribution and elimination half-life of remifentanil were (4.52 ± 1.25)min and(24.64 ± 1.30)min in group A and (4.68 ± 1.31)min and(25.45 ± 2.08)min in group B respectively,there was no statistical significance between 2 groups(P>0.05). tPDT and ePDT of group A were(8.88± 1.66)mA and(1.54±0.09)mA respectively,and those of group B were(9.16±1.58)mA and(1.34±0.15)mA,there was no sta-tistical significance between 2 groups (P>0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:The abnormal liver function of patients with liver cirrhosis following hepatitis B have no significant effect on drug half-life and analgesic effect of remi-fentanil with good safety.

In this research, we apply the antisense strategy to study the function of IGF- I in human hepatoma lines(7402) by Lipofectin mediated gene transfer. The effect of antisense IGF-I on the expression of MHC and the sensitivity of LAK cytotoxicity of tumor cell were studied. The results showed that human hepotoma lines(7402) were transfected with an amplifiable antisense IGF- I gene. The expression antisense IGF-I RNA in the transfected cells after hygromycin resistant selection was confirmed by northern blot analysis. The transfectants expressed higher level of MHC class I and class II molecules. The susceptibility of the transfected cell to LAK cytotoxicity was greater than that of 7402 parent cells(P

Objective To summarize experience in pectoralis major myocutaneous (PMMC) flap reconstruction for patients undergoing head and neck surgeries. Methods We conducted a retrospective study to analyse the clinical data of 20 patients who had PMMC flap reconstruction in a head and neck surgery from March 2011 to June 2016. All patients were male,with the average age of 54 years(ranging from 27 to 71 years). The PMMC flaps of all patients survived after the surgery. Only one patient developed pharyngocutaneous fistula ,and was recovered after treatment with incision dressing. Among follow?ups for 2 to 24 months,all patients got well recovered,the swallowing and communication functions normal communication and the appearance a satisfactory. good looking. Conclusion PMMC renders effective flathe flap reconstruction with broad clinical application value is an optimal choice for patients underwent head and neck surgery with muscle or skin defect,especially for those who had postoperative radiotherapy because of its rich blood supply and it has a lot of affluent tissues,fmore flexibility inle application and higher survival rate. So it is highly applicable,especially for grass?roots hospitals.

Objective To explore clinical characteristics of chronic total occlusion(CTO) in population with routine coronary angiography,and to cumulate therapeutic experience.Methods Retrospective analysis was performed on clinical data of 57 cases with CTO selected from 825 patients undergone coronary angiography.Results Among 57 cases,the percentage of male,myocaridial infarction,diabetes mellitus,hyperlipidermia and left ventricular dysfunction was 73.7%,84.2%,22.8%,73.7% and 22.8%,respectively.The types of lesions included single branch(n=11),double branches(n=29) and three branches(n=17).Of 70 branches lesion vessels,44 were TIMI 0 of blood flow classification and 26 were TIMI1.The position of lesions occurred at left anterior descending branch(n=32),left circumflex branch(n=16),right coronary artery(n=22).The occlusion time was less than three months(n=41) and more than three months(n=29).The lengths of lesion was divided into less than 20 mm(n=43) and more than 20 mm(n=27).The shapes of terminal lesion looked like rat-tail(n=42) and blaze knife-edge(n=28).The coronary stents were performed at 57 lesions among 70 branches and the successful rate of operation was 82.9%.Conclusions Timely coronary angiography and selecting suitable treatment on different kinds of lesions for male patients with myocardial infraction,especially complicated with diabetes mellitus,might play important roles in prevention of CTO and in improvement of the successful rate of percutanous coronary intervention for the complex lesion.
