Objective To investigate the effectiveness of interventional therapy for the atherosclerotic renal artery occlusion (ARAO). Methods During the period of June 2001-Dec. 2007, 16 patients with ARAO (total of 16 occluded arteries) underwent interventional managements, including percutaneous endovascular renal artery revascularization, balloon dilatation angioplasty and stent placement. Follow-up survey was made at regular intervals. The patent condition of the renal artery was evaluated with ultrasonography and digital subtraction angiography. The blood pressure and the renal function were determined and the data were statistically analyzed in order to assess the intermediate and long-term effect of the interventional therapy. Results Of 16 patients, technical success was achieved in 15 (93.8%) and failure occurred in one. During a follow-up period of 9 - 24 months, 3 patients died. According to the data obtained at each patient’s last follow-up survey, the hypertension fell to normal in 3 (25.0%), was improved in 7 (58.3%) and showed no marked change in 2 patients (16.7%), with a clinical efficacy of 83.3% (10 / 12). The renal function was improved in 2 (16.7%), stabilized in 6 (50%) and deteriorated in 4 patients (33.3%), with an effective rate of 66.7% (8 / 12). Conclusion For the treatment of atherosclerotic renal artery occlusion, the interventional therapy carries high successful rate and can effectively lower the blood pressure level, in addition, it can also protect the renal function in a certain degree.

Objective To compare the therapeutic effects of 1470nm diode laser vaporization prostatectomy and bipolar transurethral plasmakinetic prostatectomy (TUPKP) for treatment of benign prostatic hyperplasia (BPH).Methods From June 2015-February 2016 a total of 95 patients diagnosed with BPH were randomly divided into 2 group:52 patients were treated with TUPKP while 43 patients with 1470 diode laser.All patients were followed up with mean operative time,intra-operative blood loss,postoperative hospital stay,postoperative catheterization time,postoperative complications,international prostate symptom score (IPSS),score of life quality (QoL),maximum flow rate (Qmax),post-void residual (PVR) before and after surgery.Results Compared with data of preoperation,postoperative IPSS,QoL,Qmax,PVR in 6 months revealed significant improvement in both of two groups.IPSS of TUPKP group and 1470 group respectively dropped to 6.3 ± 2.6 and 6.7 ± 2.4.In TUPKP group,PVR reduced to 23.1 ± 20.9ml and in 1470 group decreased to 24.3 ± 19.9ml.While Qmax increased to 18.5 ± 3.1 ml/s and 18.7 ± 2.8ml/s respectively in TUPKP and 1470 group.In TUPKP group,operation time were 60.1 ± 14.9min,significantly less than that in 1470 group of 69.3 ± 12.9min (P ＜ 0.05).Compared with catheterization time in 1470 group of 33.9 ± 9.4h,the time in TUPKP group of 73.9 ± 37.6h was shorter with significant difference (P ＜ 0.05).While Curative effect of two groups of showed no significant difference (P ＞ 0.05).Conclusion The clinical curative effect of two operation methods for patients with BPH showed no significant difference.1470 group had longer operation time,while TUPKP group had less intraoperative bleeding and postoperative recovery.

Objective To discuss the diagnosis and treatment of a variety of multiple nerve entrapment in the brachial plexus and around anterior and middle scalene muscles in 179 cases.Methods From July 2003 to January 2006,179 outpatients in our department were diagnosed as thoracic outlet syndrome(TOS)with a variety of symptoms of the nerve entrapment in the brachial plexus and around anterior and middle scalene muscles.They were treated with drugs,local block injections,or operations,depending on their severity of the condition. Results Of the 128 cases who were followed up for one to 29 months,the symptoms were significantly relieved with drugs and massage in 55 cases,with local block injection in 58 cases of whom 24 received the second in- jection,with operation in 15 cases of whom 10 returned to work.One of the operated cases reported symptoms of injury to the long thoracic nerve which responded to further therapy.The visual analogue scale(VAS)evaluations after the first injection were one point in two cases,two points in 16 cases,three points in 20 cases,four points in 12 cases,five points in three cases,six points in three cases,and seven points in two cases.The VAS scores after the second injection were two points in five cases,three points in 16 cases,and four points in three cases. Conclusions The entrapment of the anterior anti middle scalene muscles can affect many nerves around the muscles,and cause clinical symptoms other than the TOS ones.The conservative treatment,such as drug,massage, and local block injection,can work well.When the non-operative methods do not work,operation can be consid- ered.

Objective To investigate the effects and mechanisms of immunosuppressants on in- duction of apoptosis of peripheral T lymphocytes.Methods T lymphocytes were derived from healthy donors and activated by super antigen SEB.The rest or activated T lymphocytes were incubated with immunosuppressants such as myophenolate mofetil (MMF),cyclosporine A (CsA),FK506,azathio- prine (Aza),sirolimus (SRL),prednisone (Pred),and daclizumab (Dac,anti-CD25mAb),alone or combined,for 3 days.The incidence of apoptosis was determined by the methods of confocal microsco- py,flow cytometer,DNA-ladder fragmentation electrophoresis,and reverse transcription-polymerase chain reaction (RT-PCR) gene amplification profiles.The quantitive assay of IL-2 and Fas in the cul- ture medium was also performed using the enzyme linked immunosorbent assay kit.Results Apoptosis in rest T lymphocytes was just induced by Pred among various immunosuppressants.MMF,Aza,and Pred promoted apoptosis in activated T lymphocytes (P＜0.05,P＜0.01),but it was blocked by CsA,FK506,SRL,and Dac (P＜0.01).After adding two or three kinds of immunosuppressants, the incidence of apoptosis in activated T lymphocytes was apparently lower than in control group (P＜0.01).The expression of Fas and IL-2 by activated T lymphocytes was inhibited by FK506 and CsA (P＜0.05).Conclusion MMF,Aza,and Pred may induce apoptosis of activated T lymphocytes via the signal pathway of Fas/Fasl.CsA and FK506 could inhibit the apoptosis of activated T lymphocytes by blocking the production of IL-2.Also,SRL and Dac can block the apoptosis of activated T lympho- cyte by interfering with the effect of IL-2 on T lymphocytes activation process.

Objective To evaluate the effect of dexmedetomidine on noise-induced hearing loss in guinea pigs.Methods Twenty-four adult male guinea pigs,aged 3 months,weighing 400-500 g,were randomly divided into 3 groups (n =8 each) using a random number table:dexmedetomdine group (group D),noise-induced hearing loss group (group N) and dexmedetomidine + noise-induced hearing loss group (group DN).A loading dose of dexmedetomidine 5 μg/kg was infused over 5 min,followed by 135 min of infusion at a rate of 10 μg· kg-1 · h-1.The equal volume of normal saline was infused in group N.Groups N and DN were exposed to noise of 4 kHz center frequency and 118-122 dB SPL for 120 min starting from 20 min of administration.Mean arterial pressure (MAP) and cochlear blood flow (COBF) were recorded before administration and every 5 min during drug administration.The changing rate of COBF was calculated.Arterial blood samples were collected for determination of plasma concentration of noradrenaline (NE) by high performance liquid chromatography at 20 and 140 min of administration.Auditory brainstem response (ABR) threshold was recorded before administration and at 1 and 72 h and 10 days after the end of administration.Results Compared with group N,MAP was significantly decreased,the changing rate of COBF was increased at 5-10 min and 30-140 min of administration,ABR threshold was decreased at 1 and 72 h and 10 days after the end of administration,and the plasma concentration of NE was decreased at 140 min of administration in D + N group (P ＜ 0.05).Conclusion Dexmedetomidine can attenuate noise-induced hearing loss in guinea pigs possibly through inhibiting activation of sympathetic nerves and increasing COBF.

Objective To investigate the clinical guiding significance of lymphoscintigraphy with 99mTc-DX for radical lateral lymph node dissection with pelvic autonomic nerve preservation(PANP) in lower rectal cancer.Methods In 67 patients with pathologically proven lower rectal cancer,37MBq/0.8ml 99mTc-DX was injected into submucosa of the rectum through rectal endoscopy.At 0.5h,1h,2h,3h,4h,6h,12h,and 24h after the injection,the patients underwent pelvic and lower abdominal lymphoscintigraphy. The operative method was determined according to the imaging results,and the results of lymphoscintigrams were correlated with postoperative lateral node histologic examination.Results The scintigrams were postive in 37 cases,and all were unilateral.The positive patients underwent PANP.The image results were compared with histological lymph node examination in all patients operated upon for rectal cancer.Histologically,the cases in conformity were 26(70.3 %),false positive in 11 cases(29.7 %),and 2 of 30 false positive patients who demonstrated metastases to lateral node were operated by PANP,while the others underwent only PANP(type Ⅰ) without lateral lymph nodes dissection.The percentage of good sexual function of the two groups of cases after operation was 74.4 % and 71.4 % respentively.The percentages of mild dysuria and good function of urination were both 100 %.Conclusions Lymphoscintigraphy with 99mTC-DX has particular guiding significance in selection of PANP for lower rectal cancer.

AIM: To determine the effect of suction duration on thickness and diameter of corneal flap created by microkeratome in porcine eyes in laser in situ kerato-mileusis (LASIK).METHODS: Sixty porcine eyes were randomly assigned to three groups according to different suction durations: group 1 (10 seconds), group 2 (20 seconds), and group 3 (30 seconds). A Moria M2 microkeratome (Moria, France) with a 160μm head was used to create a corneal flap. Corneal flap thickness was measured by automated ultrasonic pachymetry, and the flap diameter was measured by a vernier caliper.RESULTS: The flap thickness of group 1, group 2 and group 3 was 146.05±13.46μm, 157.35±18.95μm and 169.25±21.02μm, respectively. There was a statistically significant difference among three groups (P=0.001). The mean flap diameter in groups 1, 2 and 3 was 8.63±0.19mm, 8.89±0.24mm and 9.06±0.18mm, respectively. A statisti-cally significant difference was found among groups (P<0.01).CONCLUSION: In LASIK in porcine eyes, an increase in suction duration resulted in a thicker and greater flap.

Objective To investigate calcineurin signaling pathway which mediates myocardium apoptosis of right heart in rats with chronic hypoxia and the potential mechanisms of it.Methods A rat model of right ventricular hypertrophy(RVH) was established induced by chronic hypoxia(95-105 mL?L-1 O2).Used randomized block design based on different brood,30 rats were divided into 3 groups:treatment group with cyclosporine A(CsA,10 mg?kg-1?d-1,intraperitoneal injection),chronic hypoxia group,normal control group(with normal oxygen).The rats in CsA treatment group and chronic hypoxia group were exposed to normobaric chronic hypoxia(95-105 mL?L-1 O2,21 days).Apoptotic index(AI),calcineurin A?(CnA?) mRNA levels,Bcl-2 mRNA levels and the protein expression levels of CnA?,nuclear factor 3 of activated T cells(NFAT3) and Bcl-2 in right ventricle were investigated.Results 1.The AI of treatment group with CsA was higher than that in chronic hypoxia group(P
