Two hundred and five patients with a confirmed diagnosis of aldosterone-producing adenomas underwent retroperitoneal laparoscopic operation from January 1999 to December 2009 in our hospital. All cases had hypokalemia and hypertension preoperatively. Of all the cases, 80 received total adrenalectomy and 125 received partial adrenalectomy. Operations were successfully performed in all cases. The time of operation ranged from 15 to 150 min [mean(45 ±13) min] and the volume of bleeding during operation ranged from 10 to 200 ml [mean(25 ±10) ml]. The length of hospital stay ranged from 4 to 9 d [mean(6. 8 ± 1. 2) d]. All patients were followed up for 0. 5 - 2 years (mean 1. 2 years). After operations blood potassium levels returned to normal in all cases, blood pressure returned to normal in 168 cases (82.0% ) . Results indicated that partial or total adrenalectomy with retroperitoneal laparoscopy for aldosterone-producing adenomas was safe and feasible technique.

The clinical data of 21 cases of adrenal ganglioneuroma treated in our hospital from July 1988 to August 2008 were reviewed. The clinical manifestations were: lower back uncomfortableness (9 cases), paroxysmal dizziness (4 cases), central obesity ( 1 case) and 7 cases were discovered incidentally.Five cases were diagnosed pre-operationally and remaining 16 cases were diagnosed post-operationally by pathology. All patients completely recovered after surgery except one, who still had dizziness with high blood pressure. Ultrasonography, CT and MRI examinations are the main diagnostic methods for adrenal ganglioneuroma, and it is confirmed by histopathology, surgical removal of the tumor is the main therapy for the disease.

Objective To measure the levels of neutrophil elastase (NE),citric acid and pH in prostatic fluid of patients with prostatitis type Ⅲ.Methods Fifty two patients with prostatitis type ⅢA,98 patients with prostatitis type Ⅲ B and 105 health subjects were enrolled in the study.The levels of NE,citric acid and pH in prostatic fluid were measured ; the expressed prostatic secretion (EPS) routine and bacterial culture were examined,and National Institutes of Health (NIH)-chronic prostatitis symptom index (NIH-CPSI) was evaluated.The data were analyzed by independent samples t-test.Results WBC count,NE and citric acid concentrations,pH in ⅢA group were (17.9 ±5.4)/HP,(898 ±704) μg/L and (14.5 ± 1.7) ng/L,7.60 ±0.43,respectively; those in ⅢB group were (3.9 ±2.2)/HP,(93 ±76) μg/L and (21.9 ±3.8) ng/L,6.71 ±0.25,respectively; those in control group were (3.6 ±2.2)/HP,(86 ±57) μg/L and (22.5 ± 3.9)ng/L,6.48 ± 0.51,respectively.There were significant differences in NE and citrate concentrations,pH value in EPS between Ⅲ A and Ⅲ B patients (t =8.22,16.64 and 13.88,all P ＜0.05),but no difference in NIH-CPSI (t =1.90,P 8 0.05).There were significant differences in WBC count,NE and citric acid concentrations,pH in EPS,NIH-CPSI score between Ⅲ A and control groups (t =18.92,8.47,26.53,18.37 and 32.47,all P ＜ 0.05).There were no differences in WBC count,NE and citric acid concentration and pH value in EPS between Ⅲ B group and control group (t =1.38,1.55,1.02 and 1.21,respectively,all P 80.05),but there was significant difference in NIH-CPSI score between two groups (t =49.46,P ＜ 0.05).In EPS,NE concentration and WBC count were positively correlated with NIH-CPSI (r =0.819 and 0.698,respectively,all P ＜0.01),and citric acid was negatively correlated (r =-0.625,P ＜ 0.01) ; citrate was negatively correlated with WBC count,CPSI and pH value (r =-0.728,-0.644 and-0.817,all P ＜ 0.01).Conclusions The results indicate that the measurements of NE,citric acid and pH in EPS are of significant clinical value in patients with prostatitis type ⅢA and Ⅲ B.

[Objective] To observe the clinical effect of TCM diet therapy on type-2 diabetes.[Method] Select the said patients 76 cases,randomly divide them into treatment group and control group with 38 cases in each group,which were administered with routine western medicine,while the treatment one was added with TCM diet medication.[Result] Compare the fasting glucose before medication,showing marked difference(P

Objective To study on wavelet transform in calcium sparks image de-noising when excitation contraction cou-pling(ECC) was studied and researched by scanning confocal microscopy,in order to elucidate the mechanism of ECC.But due to the noise exist in most calcium sparks image,it is hardly to recognize and analyze the useful information of calcium sparks.So how to increase the signal-to-noise rate is very important in calcium spark studying.Methods By using the self-developed software based on multi-scale wavelet transform to remove the noise exists in the calcium sparks images.Results The experiments shows that the method can be increased the signal-to-noise rate in about 80 calcium sparks images.Con-clusion The new method for calcium spark expression and spatial and temporal analysis is provided.

This paper gives the techniques and steps of creating remote control instruments system using Windows API functions,and explains its hardware and software structures.The whole system is proved to be stable and reliable by experiment.It can provide a new experimental method for biomedical research,which enable the construction of multifunctional experiment platform.

Wavelet transform(WT) is a powerful technique in signal separation and can improve the signal-to-noise ratio by separating the white noise and useful signal.The method in the paper introduces the concepts of Wavelet transform.According to the analysis of Wavelet coefficients between the noise and signal at different levels,the appropriate filter is realized.The patch clamp experiment results demonstrate the feasibility of the method.

Fluorescence probe Fluo-3AM can be luminary in confocal microscope after combining Ca2+,So nomadic Ca2+ in cytoplasm can be measured and tested by this way.Some confocal laser scan images are obtained after calcium in muscle fibers signed with F1uo-3AM. Then mapping function is used to convert the gray level image into colorful image by pseudo-color enhancement theory in digital image.Compared to the original gray level image,the processed pseudo-color image could be more easily distinguished.So the methods had a great value in Ca2+ detection fields.

Objective To discuss the method of calling MATLAB in VB application program based on ActiveX.Methods MATLAB provided automatic service support to ActiveX,and MATLAB could be called as ActiveX of interpreter through ActiveX automatic interface.Results Good effect was achieved when this method was applied to noise filtering of patch clamp.Conclusion By using this method,users can embedded mix programming in self-developed application software conveniently,thus reducing the difficulties in programming.

Objective To retrospectively analyze the intraoperative complications of laparoscopic radical prostatectomy (LRP) during the initial application, so as to analyze the reasons and summarize the experience. Methods The videos of the 60 patients undergoing LRP for prostate cancer in our hospital between January 2010 and November 2012 were reviewed to analyze the intraoperative complications. The patients were the first 20 casesdone by 3 surgeons independently. The clinical data, tumor staging, and other related factors were collected for analyzing the reasons for complications of LRP. Results Complicationswere observed intraoperatively in the 23 patients. The most frequent complications included mistaken suture of bladder catheter (7 cases), openconversion due to intraoperative bleeding (5 cases), residual prostate tissue (5 cases), secondary anastomosis (4 cases), rectal injury (1 case), and specimen missing (1 case). All the events were managed during the operation. The reasons for the complications included unclear anatomical structure, unclear surgical landmark, poor cooperation with assistants, and inconsiderate operative details. Some patients were in the advanced stage, making it difficult to perform the operation. Conclusion The patients with low surgical risk should be chosen for the initial application of LRP, and a stable operation team should be formed. A standard strategy should be formed regarding the equipment selection, surgical procedure, anatomic marking, and manipulation based on viewing the operation; and improvement should be made gradually in practice.
