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 compare the different micro inflammatory states between pafients undergone peritoneal dialysis and the pafients of chronic renal failure without dialysis,and to observe the condition of the occurrence of the micro inflammatory state in the peritoneal dialysis patients.Methods This study included 53 peritoneal dialysis patients who were followed-up in our dialysis center,34 chronic renal failure patients without dialysis and 47 normal controls,hs-CRP,IL-6,IL-8,TNF-? in venous blood were defected with empty stomach,and then compare the number of patients in each group.Results Patients'hs-CRP of the group of the PD is lower than that in the group of the chronic renal failure without dialysis,and higher than that in the normal people(P

OBJECTIVE To develop a rapid method for simultaneously identifying Staphylococcus aureus(SA) and its resistance against meticillin. METHODS The target strains authenicated to Staphylococcus by traditional methods(appearance,Gram-stain,catalase) first,then using Slidex~staph.plus to authenticate SA;establishing traditional method or coagulase test and ATB-ID32STAPH system for verification.The penicillin-binding protein 2a(PBP2a) was examined by Slidex MRSA Detection,establishing resistance oxacillin sieving test and mecA gene was examined by PCR for verification. RESULTS The 135 strains were positive and 321 strains were negative for Slidex~staph.plus from 456 strains.The 127 S.aureus strains and eight others were confirmed from 135 positive strains finally,11 SA strains and 310 other strains were confirmed from 321 negative strains,there were 92.0% for sensitivity and 97.5% for specificity in this method.The 52 strains PBP2a positively confirmed to meticillin-resistant S.aureus(MRSA) using Slidex MRSA Detection and 57 MRSA strains were confirmed using resistance oxacillin sieving test or PCR from 138 strains.There were 91.2% for sensitivity and 100% for specifity in this method. CONCLUSIONS The duplex Slidex~-staph monoclonal antibody examinated to SA and confirmed to MRSA has higher sensitivity and specificity.

Objective To study the effects of cardiac and pulmonary response in pailents with chronic obstructive pulmonary disease(COPD) on their exercise capacity.Methods Thirty four patients with COPD(including 8 patients in stage Ⅰ,15 patients in stage Ⅱ,10 patents in stage Ⅲ and 1 patent in stage Ⅳ and 24 healthy controls performed incremental exercise testing.Oxygen uptake(VO_2) and carbon dioxide output(VCO_2)were measured breath-by-breath.Arterial blood samples were drawn both at rest and peak exercise.Results The VO_2 at peak exercise was significantly lower in COPD group than in control group(15.81±3.65ml/min/kg vs 18.96±6.10ml/min/kg,P=0.042).The respiration reserve was lower in COPD patients compared to controls.The rBorg dyspnea score at the peak exercise for COPD patents was 4.24±2.01,significantly higher than that for controls(1.754±1.50).Oxygen pulse and heart rate reserve had not statistically difference between COPD group and control group.Significant increase of PO_2 and PCO_2 were found during exercise,which were 26.374±15.40 vs 10.26±22.65 mmHg and 42.33±3.65 vs 40.29±4.46 mmHg respectively compared to at rest.Conclusion Abnormal pulmonary response to exercise might be the main cause inducing exercise intolerance in patents with COPD.

Objective To investigate the feasibility and efficacy of posterior retroperitoneoscopic adrenalectomy (PRA).Methods To review the clinical data of 35 patients who underwent posterior retroperitoneoscopic adrenalectomy from September 2013 to September 2015.There were 14 males and 21 females, aged 15-70 years, with an average of 45.8 years.Preoperative CT scan was performed to determine the size, shape and location of the tumor.Tumor diameter 10-60 mm, average 31 mm.Results 35 operations were successfully accomplished via the posterior approach.The operation time was 38-138 min (mean 70.1 min) ,and the drainage tube indwelling time was 1-5 d(average 2.1 d) ,the hospital stay was 2-6d(average 3.7 d).Total hospital costs were 14 789-31 992 yuan, average of 21 239 yuan.No complications occurred during the perioperative period.Conclusions Posterior retroperitoneoscopic adrenalectomy might provide clear anatomical views.It could be a safe and effective operation for the clinical treatment of adrenal tumors.

In order to study the variation of complex impedance and characteristic parameters on human normal and tumor lung tissue during the extracorporeal time, we established a real part-imaginary part chart of complex impedance on lung tissue which provided the basic theory and the reference data for research on elementary medicine and clinical diagnosis of lung cancer and meanwhile provided prior information for electrical impedance tomography (EIT) research. In the experiment carried out in our laboratory, when operation was finished, we kept the lung cancer tissue and normal tissue neatly separated into the cylindrical testing cavities and kept the temperature and humidity at expected values. Then the measurements of complex impedance property are performed at frequency from 1 000 Hz to 30 MHz using 4294A impedance analyzer of Aglient Company. With time changing, the results showed that there was a significant change occurring on the complex impedance of human normal and tumor lung tissue. However, the impedance of normal lung tissue is greater than that of tumor lung tissue. We consider that this change should be related to the change in extracellular fluid, intracellular fluid and cell membrane.

Abstract Objective: To study the relationshiop between the HBV pre-c mutant and the clinical the, the host immunity. Methods: Mu-tation specific PCR(msPCR) was employed for detecting pre-c mutant in 92 cases with HBV-DNA positive;T subpopulations were determinedby APAAP immune-bridge assay; the cytokines (TNF?、 sIL-2R ) levels by ELISA. Results: 57 cases had Pre-c mutant, the rate was ahaut 62 %;pre-c mutant existed popularly in different e systems status, mainly in anti-HBe(+) serum. The reat increased with the deterioration of liverfunction, and was highest in fulminant hepatitis, the percentage of CD4 T lymphocyte and the ratio of CD4/CD8 were aignificantly lower in mu-tational group than in wild group,but CD8 T lymphocyte was obviously higher, the quantity of sera TNF? and sIL-2R in mutational group wereobviously higher than in wild group, both groups were obviously higher than control group. Conclusion:PreC 1896 mutant existed popularly inpatients with HBV infection. There were more serious disturbance in host immunity in mutant group. The mutant may be associated with the pre-ssare of host immune system.The mutant type virus could provoke host immunity resulting in severe liver damage.
