Objective To study the clinical and pathological features, diagnosis and treatment of malig-nant mesothelioma of the tunica vaginalis testis. Methods One case of malignant mesothelioma of the tuni-ca vaginalis testis was reported. The patient was a 73 years old man, presented with a history of aggravated hydrocele for 1 year. B-ultrasound showed 7.5 cm×4.1 cm liquid anechoic area around the testis. The Pubmed and CBM databases were searched for related articles, and the clinical data were reviewed. Results An operation was performed to incise the tunica vaginalis. The pathology showed fecal caneeration in the tunica vaginalis testis and the immunohistology showed CK5/6, Calretinin and E-cadlberin positive. Right or-chiectomy was performed after three weeks. Local tumor recurrence and inguinal lymph nodes metastasis were found 11 months after operation, and local tumor and lymph nodes were resected. The tumor was diagnosed as malignant mesothelioma of the tunica vaginalis testis and CK5/6 and Calretinin fecal positive. Conclu-sions Malignant mesothelioma of the tunica vaginalis is a rare disease of the testis with potentially aggres-sive behavior. Due to the lack of tumor markers and characteristic symptoms, correct preoperative diagnosis is extremely difficult. Radical surgical treatment is of major importance to the survival of the patients. Life-long follow-up should be offered to patients with malignant mesothelioma of the tunica vaginalis.

Under the condition of pH 0.8～1.0, lead concentration was examined by Hydridegeneration Atomic Fluorescence Spectrometry.Results The method had good linearity when lead concentration were between 0 to 600 ?g/L, r =0.999. The within-run CV of the method for high, middle and low lead level were 4.1%, 3.6% and 3.5% respectively. The between-run CV were 4.9%, 4.6% and 4.7% respectively. The recovery rates were 105.4%, 98.5% and 94.8% respectively. The single-blind test result of series standard lead samples provided by Chinese Academy of Preventive Medicine were within the acceptable range. The detecting Limit of this method was 0.3 ng. There was no significant interference from main two-valence positiveion. The sample can be storage at lest for 1 months at 4℃. Samples of 869 children from Tianjin were tested by this method. The mean value was 91.9 ?g/L, median was 83.8 ?g/L, all data were within 23.1～386.3 ?g/L. The result showed out positive skewness distribution.Conclusion This method were sensitive, accurate, precise, quick and low-cost. It was suitable for use in clinical laboratories.

Objective To combine grey relation analysis and partial least squares regression model to establish the forecasting model of per-patient hospitalization expenses .Methods Gray relational analysis was used to filter out the main factors affecting per-patient hospitalization expenses ,and then collinearity was examined between these factors .Partial least squares regression was used to establish prediction model of per-patient hospitalization expenses ,and the prediction accuracy was proved .Results After filtered by gray relational analysis ,the order of the importance of factors affecting per-patient hospitalization expenses was the west-ern medicine fee ,traditional Chinese medicine fees ,diagnosis and treat fees ,other fees ,inspection fees ,bed fees and operation fees . The established partial least squares regression model had a higher accuracy on fitting and prediction ,with low average relative er-ror ,respectively ,-0 .000 2% and 0 .349 3% .Conclusion The gray relational analysis and partial least squares regression are suit-able for the influencing factors and prediction analysis of hospitalization costs .It provides a reference for data with the small sample size and high collinearity between the variables .

Objective To explore the medication rules of Professor WEI Pin-kang in treating gastric cancer; To provide references for clinical medication. Methods Gastric cancer cases treated by Professor WEI Pin-kang in TCM outpatient department of Shanghai Changzheng Hospital from January 2008 to December 2015 in WEI Pin-kang TCM Studio Outpatient Medical Cases (including electronic database and paper medical cases database). TCM Inheritance Support System V2.5 was used to build database. Frequency analysis, association rule analysis, complex system entropy clustering and other data mining methods were used to analyze frequency, medicine association rules and core medicine combination. Results Totally 305 clinical prescriptions including 185 kinds of Chinese materia medica were collected. The Chinese meteria medica with the high frequency were Pinellinae Rhizoma Praeparatum, Arisaematis Rhizoma Preparatum and Galli Gigerii Endothelium Corneum, etc. High frequency Chinese materia medica were with the properties of warm and cold, and with the flavors of bitter, spicy and sweet, to Stomach Meridian of Foot-Yangming, Spleen Meridian of Foot-Taiyin, and Liver Meridian of Foot-Jueyin. The medicine combinations with high frequency were Pinellinae Rhizoma Praeparatum and Arisaematis Rhizoma Preparatum,Pinellinae Rhizoma Praeparatum and Galli Gigerii Endothelium Corneum, and Galli Gigerii Endothelium Corneum and Arisaematis Rhizoma Preparatum. The common medicine pairs were Aurantii Fructus and Aurantii Fructus Immaturum and Scorpio and Scolopendra.

Radiotherapy and chemotherapy have little or no effect on advanced renal cell carcinoma, leading to a poor prognosis. Several factors couLd affect the survival rate of RCC. Some RCC patients could partly respond to immunotherapy.The newly emerging targeted therapy has a dramatic tuning point in improving outcomes for RCC. Further understanding of the anti-RCC mechanisms involves in chemokine-mediated angiogenesis and RCC cell proliferation. These new agents include Sorafenib, Sunitinib, Temsirolimus, Bevacizumab, etc. Combination treatment with immunotherapy may lead to improved outcomes in this disease.

Objective To investigate the curative effect of RevoLix 2 micron continuous wave laser va-poresection for treatment of elderly and high risk benign prostatic hyperplasia patients. Methods Clinical data of 36 benign prostatic hyperplasia patients with medical complications aging 70 -82 years were retro-spectively analyzed. Operations were done after their complications were controlled. The RevoLix 2 μm laser system with output power of 70 W was used, and normal saline was used as rinse solution. Operations were started after positions of seminal colliculns and distances to neck of bladder were confirmed. Results Oper-ation time varied from 65 to 135 rain with a mean time of (83.6±10. 6) rain. Occasional venous hemor-rhage occurred during operation but no arterial hemorrhage was observed. No blood transfusion necessitated and no TURP syndrome was observed. Catheter was removed 2-4 days after operation. All the patients could urinate freely. No urinary incontinence was found during follow-up except 2 patients with temporary urinary incontinence. A 3-6 months follow-up showed that IPSS decreased from 24. 26 ±2. 70 to 8.47±4. 32, QOL dropped from 4. 51±0. 56 to 1.34 ± 0. 53, and Qmax increased from (6. 37 ± 1.31) mL/s to (17.24± 2. 32) mL/s.
