1.Application of percutaneous transluminal angioplasty in hemodialytic patients with arteriovenous fistula stenosis
Chinese Journal of General Practitioners 2017;16(1):61-63
Arteriovenous fistula stenosis developed in 32 patients who received hemodialysis from April 2014 to April 2016, including 24 cases of autologous arteriovenous fistula ( AVF) and 8 cases of artificial vessel arteriovenous fistula ( AVG).In AVF patients, there were 20 cases with blood flow decreasing and 4 cases of venous hypertension , while in AVG patients there were no cases with blood flow decreasing and 8 cases with venous pressure increasing (χ2 =17.77, P<0.001).All patients underwent percutaneous transluminal angioplasty ( PTA ) . In all patients the vascular diameter was increased significantly after PTA treatment [(3.6 ±0.2) vs.(1.2 ±0.1) mm, t=18.52, P<0.001].The blood flow during hemodialysis was increased significantly after PTA treatment in patients with anastomoti stenosis [(265.4 ±21.5) vs.( 150.5 ±23.1 ) ml/min, t =21.81, P <0.001 ]; however, there were no significant changes in venous pressure [(68.6 ±8.7) vs.(69.3 ±6.1) mmHg(1 mmHg=0.133 kPa), P>0.05].The blood pressure was decreased after PTA treatment [( 71.2 ±7.9 ) vs.( 170.4 ± 15.7) mmHg, t=34.62, P<0.001] in patients with venous outflowtract stenosis , however, there were no significant changes in the blood flow [(264.1 ±15.2) vs.(260.7 ±17.3) ml/min, t=1.04, P>0.05].

International Journal of Laboratory Medicine 2015;(3):298-300
Objective To evaluate the diagnostic value of combined test of C-reactive protein,amylase and lipase for acute pan-creatitis patients in early stage,and its practicability in assessment of disease severity.Methods 71 cases of acute pancreatitis pa-tients in the hospital from March 2012 to March 2014 were enrolled in the study,including 60 cases of mild pancreatitis patients,11 cases of severe pancreatitis patients.Meanwhile,30 cases of non-acute pancreatitis patients were enrolled as Control Group A,and 50 cases of adults who underwent conventional examination and proved to be healthy were enrolled as Control Group B.Detection of C-reactive protein,amylase and lipase of these samples were performed and the results were recorded,compared and analyzed.Re-sults The serum amylase level of acute pancreatitis patients was (759.42±721.63)U/L,and serum lipase level were (1 624.34± 1 598.25)U/L,which were significantly higher than people in Control Group A and Control Group B,with statistical significance (P <0.05).However,C-reactive protein level of acute pancreatitis patients were (44.61±34.21)mg/L,which were not statistical-ly different compared with Control Group B.Combined test of the three indicators demonstrated that the sensitivity was 95.9%, specificity was 100% and accuracy was 96.9%,all of which were higher than other test combinations or singe test with statistical significance(P <0.05 ).Conclusion The combined test of C-reactive protein,amylase and lipase for acute pancreatitis patients doesn′t only improve early diagnostic efficiency,but also is helpful in disease severity judgment.

Journal of International Oncology 2010;37(4):272-275
Tumor markers play an important role in tumor mass screening, diagnosis and differential diagnosis of tumor, tumor staging, therapeutic evaluation and prognosis assessment. According to the nature,tumor markers can be classified as follows: embryonic antigen, carbohydrate antigens, proteins, enzymes, hormones, and so on. And tumor markers have been used in clinical widely.
5.The changes in cerebral metabolism and depth of anesthesia during hypothermic cardiopulmonary bypass
Chinese Journal of Anesthesiology 1996;0(09):-
Objective To evaluate the effects of hypothermic cardiopulmouary bypass(CPB) on depth of anesthesia measured by BIS and auditory evoked potential index(AEPI) monitoring and cerebral O_2 and glucose metabolism. Methods Twenty-eight ASA Ⅱ-Ⅲ patients of both sexes(15 males, 13 females) aged 29-55 yrs undergoing elective cardiac valve replacement under hypothemic CPB were studied. Patients were excluded from the study if they had hearing disturbance, hepato-renal dysfunction, diabetes melhtus, hypertension, cerehro-vascular or mental diseases. The patients were premedicated with intramuscular morphine 0.15 mg?kg~(-1) and scopolamine 0.3mg. Anesthesia was induced with midazulam 0.05-0.1 mg?kg~(-1), fentanyl 10 ug?kg~(-1) and pancuronium 0.1 mg?kg~(-1) and maintained with intermittent ⅰ.ⅴ. boluses of fentanyl, diazepam and pancuronium. Radial artery was cannulated for BP monitoring and blood sampling. A CVP catheter was inserted into right internal jugular vein and advanced in a cephalad direction until jugular bulb for blood sampling. BP, HR, T℃(naso-pharyngeal), BIS and AEPI were continuously monitored during operation. Arterial and jugular bulb blood samples were obtained before CPB(T_1), T℃ was lowered to 33℃(T_2)during stable hypothermia(T_3) during rewarming at 33℃(T_4) and 30 min after termination of CPB(T_5) for blood gas analysis and determination of glucose and lactate concentrations. Cerebral oxygen extraction rate(O_2 ER) cerebral glucose extraction rate(GER), arterial-jugular bulb venous lactate difference(DLa-jv) and arterial-jugular bulb venous O_2 content difference (Ca-jvO_2) were calculated. Results Blood glucose and lactate concentrations were significantly increased, while arterial blood pH and DLa-jv did not change significantly during CPB. Cerebral oxygen extraction rate(O_2ER), cerebral glucose extraction rate(GER) and arterial-jugular bulb venous O_2 content difference (Ca-jvO_2) decreased while jugular bulb venous oxygen saturation (SjvO_2) increased with decreasing body temperature. BIS and AEPI values decreased with decreasing T℃ and both were well correlated with T℃. AEPI was positively correlated with O_2 ER and negatively correlated with Ca-jvO_2 whereas BIS was positively correlated with PaO_2. Conclusion Cerebral metabolism is decreased during hypothermic CPB which also deepens anesthetic depth measured by BIS and AEPI monitoring.

OBJECTIVE: To establish the HPLC method for the determination of chloramphenicol and dapsone in compound chloramphenicol cream. METHODS: The analytical column was Hypersil ODS and the mobile phase consisted of 0.1%sodium heptanesulfonate solution (a mixture of 0.1% sodium heptanesulfonate 500 mL and dimethylformamide 5 mL plus acetic acid glacial 0.5 mL)-acetonitrile (75∶25) at a flow rate of 1.0 mL?min-1. The detection wavelength was 272 nm and the sample size was 20 ?L. RESULTS: The linear ranges of chloramphenicol and dapsone were 25.59~153.54 ?g?mL-1 (r=0.999 9) and 12.57~75.42 ?g?mL-1 (r=0.999 9), respectively. The average recovery rates were 100.62% (RSD=0.92%) and 100.93% (RSD=1.22%), respectively. CONCLUSION: The method is simple and accurate and can be used for the quality control of compound chloramphenicol cream.
8.Nitric oxide synthases in erectile dysfunction
Chinese Journal of Pathophysiology 2000;0(07):-
With the illustration of the L-Arg-NO-cGMP pathway in penile erection,the researches on nitric oxide synthases(NOSs),which produce nitric oxide(NO)as the main messenger to control the process,has stayed in the spotlight.nNOS locates in neuroal tissues and eNOS is binding on the membrane of cavernous sinus endothelium with caveolin.The nNOS & eNOS are expressed constitutively.The activation of nNOS & eNOS is more dependent on Ca2+ concentration than iNOS,which is seldom expressed except in aged or pathological conditions.It is now clear that nNOS may initiate cavernosal tissue relaxation under the regulation of PDZ zone when transcripted,while phosphorylated eNOS may facilitate attainment and maintenance of full erection.iNOS expression stimulated by the cytokines may be beneficial(cytoprotective or anti-fibrotic)or deleterious(cytotoxic)according to the tissue environment.Gene therapies based on NOSs have attained a great deal of achievements in animal experiments and will promise a wonderful future.
