Although primary vesical calculi is an ancient disease, the mechanism of calculi formation remains unclear. In this study, we established a novel primary vesical calculi model with d,l-choline tartrate in mice. Compared with commonly used melamine and ethylene glycol models, our model was the only approach that induced vesical calculi without causing kidney injury. Previous studies suggest that proteins in the daily diet are the main contributors to the prevention of vesical calculi, yet the effect of fat is overlooked. To assay the relationship of dietary fat with the formation of primary vesical calculi, d,l-choline tartrate-treated mice were fed a high-fat, low-fat, or normal-fat diet. Genetic changes in the mouse bladder were detected with transcriptome analysis. A high-fat diet remarkably reduced the morbidity of primary vesical calculi. Higher fatty acid levels in serum and urine were observed in the high-fat diet group, and more intact epithelia in bladder were observed in the same group compared with the normal- and low-fat diet groups, suggesting the protective effect of fatty acids on bladder epithelia to maintain its normal histological structure. Transcriptome analysis revealed that the macrophage differentiation-related gene C-X-C motif chemokine ligand 14 (Cxcl14) was upregulated in the bladders of high-fat diet-fed mice compared with those of normal- or low-fat diet-fed mice, which was consistent with histological observations. The expression of CXCL14 significantly increased in the bladder in the high-fat diet group. CXCL14 enhanced the recruitment of macrophages to the crystal nucleus and induced the transformation of M2 macrophages, which led to phagocytosis of budding crystals and prevented accumulation of calculi. In human bladder epithelia (HCV-29) cells, high fatty acid supplementation significantly increased the expression of CXCL14. Dietary fat is essential for the maintenance of physiological functions of the bladder and for the prevention of primary vesical calculi, which provides new ideas for the reduction of morbidity of primary vesical calculi.

【Objective】 To explore and evaluate the application of blood intelligent management platform (scheme) based on the Internet of Things(IoT)in the clinical blood management for hospitals. 【Methods】 Based on radio frequency identification technology (RFID), smart blood refrigerators, IoT blood shipping containers, automated blood bank systems, smart blood management software, etc. were developed and integrated as an IoT blood intelligent management platform (scheme). The blood storage, management software and hardware systems were organically combined, and the blood storage equipment was moved forward to the clinical departments to solve the concerns of clinicians. 【Results】 The in-depth integration of IoT technology, RFID and refrigeration technology has built an RFID-based IoT blood management solution, which integrates blood storage, transfusion, and quality control management, also realizes the entire process of supervision and traceability of clinical blood transfusion. The forward movement of blood bank to the clinical departments and the implementation of electronic cross-matching streamlined and optimized the clinical blood flow. The waiting time of patient′s for blood transfusion was shortened from (40±10) min to less than 2 min. The whole process of cold chain logistics ensured the storage quality of blood products issued, so that the clinical departments can return the untransfused blood and Blood Transfusion Department can reissue it to other hospitals. 【Conclusion】 IoT blood intelligent management based on RFID realizes the intelligent management of clinical blood transfusion and blood information traceability. The forward movement of blood bank to the clinical departments improves the efficiency of clinical blood transfusion, avoids the waste of blood source, and ensures the safety of blood transfusion. It is worth promoting in the whole process of blood transfusion.

Objective To summarize the relationship between metabolic syndrome (MS),its components and T1 stage with high grade urothelial carcinoma (HGUC) of the Bladder.Methods The clinical data of 200 patients with T1 high grade bladder cancer who were admitted to our hospital from January 2010 to June 2014 were retrospectively analyzed,including 155 males and 45 females.Ages were 24 to 86 years old,average 66 years old.Based on the history or blood glucose levels,patients were divided into diabetic group (n =41) (20.5％) and non diabetes group 159 cases (79.5％);According to the body mass index (BMI) were divided into obese group (≥25 kg / m2) of 98 cases (49.0％) and non obese group (＜ 25 kg / m2) of 102 cases (51.0％).According to the blood pressure level,71 cases (35.5％) were divided into hypertension group and 129 cases of non hypertension group (64.5％).MS and its components and the relationship between the recurrence and progress of bladder cancer were analyzed.The Kaplan Meier method was used to assess MS and its components division of tumor progression free survival (progress-free survival,PFS) and recurrence free survival (recurrence-free survival,RFS) influence.Cox regression model of multi factor analysis were used to evaluate the PFS and RFs of MS and its components with bladder cancer.Results Of the 200 cases,16 cases (8.0％) were MS.Tumor recurrence occurred in 121 cases (60.5％),and 84 patients (42.0％) were in progress.Diabetes and non diabetes groups the average RFs were 21.7 and 29.3 months respectively,and the difference was statistically significant (x2 =10.115,P =0.001);The median PFS were 32.8 and 39.8 months respectively,the difference has statistical significance (x2 =14.760,P ＜0.001).Obese group and non obese group average RFs were 34.7 and 42.0 months respectively,and the difference were statistically significant (x2 =16.077,P ＜ 0.001);The median PFS were 22.8 and 32.6 months respectively,the difference was statistically significant (x2 =16.174,P＜0.001).The average RFS of MS group and non MS group were 21.5 and 28.4 months respectively,the difference was statistically significant (x2 =5.429,P =0.02);the average PFS was 35.1 and 38.7 months respectively,and the difference was statistically significant (x2 =3.854,P ＜ 0.05).Cox multivariate survival analysis showed that diabetes and obesity can increase the risk of recurrence and progression of T1 advanced stage bladder cancer (HR =1.792,P =0.013,HR =2.498,P ＜ 0.001;HR =0.559,P ＜ 0.001;HR =0.492,P ＜ 0.001).Conclusions Diabetes mellitus and obesity are high risk factors for the recurrence and progression of T1 advanced stage bladder cancer,but MS is not related to the prognosis of T1 patients with advanced bladder cancer.

Objective To analyze the diagnosis,treatment and prognosis of small cell carcinoma of bladder (SCCB) in order to improve the understanding of it.Methods The pathological and clinical data of 5 cases of SCCB were retrospectively analyzed.All patients were male,aged 50 to 78 years (mean age,64 years).Clinical manifestations of 4 cases were gross hematuria,the other case was found by health examination.Ultrasonography results of 3 cases were medium echo tumors,the other 2 cases were hypoecho tumors.The diameter of the tumor was 2.1 to 4.0 cm (mean,3.0 cm).There were 3 patients accepted CT scan.One of them was found of hydronephrosis and multiple pelvic lymph nodes.All patients accepted diagnostic TURBT.Three of them accepted postoperative chemotherapy (1 cycle) without other surgery.Two patients accepted radical cystectomy with postoperative chemotherapy (3 cycles) after bladder tumor biopsy.Results Pathological findings showed that tumor cells were small,round and sheet in arrangement.These hyperchromatic nuclei showed limited cytoplasm with lack of nesting character.Neuron specific enolase,chromogranin A and synaptophysin were positive in immunohistochemistry.The final diagnosis was SCCB'.Two of the three patients who accepted TURBT with postoperative chemotherapy died 7 and 8 months postoperatively,the other one was alive for 32 months.Another two patients who accepted radical cystectomy with postoperative chemotherapy were alive for 16 and 26 months.Conclusions SCCB is a rare tumor which has high malignancy and poor prognosis.Radical cystectomy in combination with postoperative chemotherapy is the main treatment.Retained bladder surgery with chemotherapy is an alternative choice.

Objective To study the preparation and stability of paclitaxel self-microemulsifying drug delivery system ( PTX-SMEDDS) . Methods The formulation of the PTX-SMEDDS was optimized by monitoring the appearance, particle size, concentration, relative substance, and bacterial endotoxin.
