Objective To evaluate the key technique and effectiveness of potency preservation in robotic-assisted laparoscopic radical prostatectomy (RALP).Methods The complete clinical and follow-up data of 30 cases underwent RALP between February and May of 2016 were reviewed retrospectively.The average age of the patients was 67.3 years (48-82 years).The peak PSA level before surgery ranged from 7.6 to 53.4 ng/ml with the average level of 21.1 ng/ml.There were 7,16,6 and 1 case with the Gleason score of 6,7,8,and 9 point,respectively.Preoperative erectile score (IIEF-5) of the 30 patients were list as below:3 cases (0-10 points),4 cases(11-15 points),17 cases(16-20 points),and 6 cases(21-25 points).The key techniques of potency preservation during RALRP includes deep dorsal vein ligation techniques,neurovascular bundles preservation techniques and drain tube placement techniques.Results All 30 cases underwent operation successfully with no transfer to open surgery.Average operative time was 150.7 min (98-240 min) with an estimated blood loss of 165.7ml (50-550 ml).The average drainage removal time was 5.1 d postoperatively.The average bowel recovery time was 2.7 d and average hospitalization time was 8.2 d,respectively.There were two cases with one positive margin on the bladder neck and one on the tip of prostate,respectively.Seventeen cases gained potency preservation six months after surgery.Conclusion It was safe and beneficial for the potency preservation in RALP,which could be considered as one of the best options for the prostate cancer surgery.

Objective To create a model with simple expression of mechanical characteristics of the human chest for the development of a manikin. Methods A simplified Gruben-model was proposed based on the anatomical structure and physical characteristics of the materials, and perfect coefficients were computed. The model feasibility was proved by the coefficient of determination and residual analysis.Results The mathematic form of the model provided had three fewer terms than Gruben′s. The coefficient of determination approximated 1, the residue was small, and the perfect coefficients of "a typical human" were determined.Conclusion The hypothesis of the model makes the coefficients physically meaningful, which provides a new method to study the force-displacement relationship of the thorax. Also the simple form makes it easy to create the model and provide some guidance for the design of a manikin′s chest.

Objective:To determine the inhibitory effect of Rupixiao ( RPX) granule on mammary gland hyperplasia ( HMG) in rabbits and explore the possible mechanism to provide reference for clinical medication. Methods:Rabbit model of mammary hyperpla-sia was established by estradiol benzoate and progesterone. Xiaoyao pills and tamoxifen were used as the positive control, and the RPX granule group was respectively at low, medium and high dose (0. 525,1. 05,2. 1 g·kg-1). Each group was with intragastric adminis-tration for 30 days. The levels of E2 , PROG, FSH, LH and PRL in serum and the expression of VEGF in the homogenate tissue were determined by an Elisa method. The breast tissue of rabbits in each group was withdrawn to observe the structure changes after Hema-toxylin-eosin staining ( HE) . Results:Ovarian preservation-benzoic acid, estradiol combined with progesterone could be used to estab-lish mammary gland hyperplasia in rabbits. RPX granule could significantly decrease the serum levels of E2 and PRL (P<0. 01)and increase that of PROG (P<0. 01 or P<0. 001). The results of pathological section showed that the breast structure in RPX granule high dose group could be restored to the level of the blank control group, which showed its therapeutic effect on HMG was better than that of tamoxifen and Xiaoyao pills. The expression of VEGF in each treatment group significantly decreased compared with that in the model group by the Elisa reagent (P<0. 001). Conclusion:RPX granule has good efficacy in HMG rabbits. The inhibitory effects of RPX granule on HMG in rabbits maybe related to the inhibition of VEGF in rabbit breast tissues, and the inhibition of RPX granule was similar to that of tamoxifen and Xiaoyao pills.

Conclusion The Mammotome biopsy system has many advantages for the diagnosis and treatment of breast lesions, including accurate localization, minimal invasion, safety and good cosmetology.

OBJECTIVETo establish and evaluate a BA-ELISA method for the quantitative detection of cystic fibrosis transmembrane conductance regulator (CFTR) protein.

METHODSWe deliberately selected three tables of CFTR and made the synthetic peptide be expressed in E. coli, then used the antigen to immunize rabbits to obtain the anti-CFTR polyclonal serum. After that, 96 well plates were coated with the purified antibody against CFTR. The antigen CFTR which was extracted from human sperm was detected by anti-CFTR antibody labeled with biotin, horseradish peroxidase conjugated avidin, and the substrate. The concentrations of two kinds of antibodies and the experiment parameters were optimized. Thereby, the double antibody sandwich BA-ELISA method for the quantitative detection of CFTR protein was established. Furthermore, the reproducibility, specificity and so on were evaluated by clinical specimens of sperm.

RESULTSThe optimal concentration of coated anti-CFTR IgG was 4 µg/ml, while the biotin labeled anti-CFTR IgG was 10 µg/ml; the optimal blocking buffer was 1% BSA-PBST, the optimal time of the reaction between antigen and antibody was 60 min, the optimal chromogenic time was 15 min, the intra-assay and inter-assay coefficient were 2.16%-9.23% and 2.29%-11.71% respectively; The lowest detectable limit was 0.15 ng/ml; the standard curve had a good linear correlation of R2 = 0.962.

CONCLUSIONThe BA-ELISA method for the quantitative detection of CTFR protein is successfully established, and it is demonstrated that the method has strong specificity, high sensitivity and good reproducibility. It provides the basis and evidence of the further application of the method.

Analogous formulae (AF) refer to a set of traditional Chinese medicine (TCM) formulae sharing similar herbs and/or indications. Dissecting functional chemome of analogous formulae could enhance the understanding of the intrinsic nature of TCM. In this study, taking 5 Xiaoqinglong decoction analogous formulae (XQL AF) including Xiaoqinglong decoction, Mahuang Xingren Shigao Gancao decoction, Mahuang Fuzi decoction, Houpu Mahuang decoction and Daqinglong decoction as example, we systematically investigated the relationship between compounds and indications using network formulaology approach. The functional chemome of XQL AF were revealed by network analysis and molecular docking. This successful application in XQL AF suggests network formulaology could be a useful tool for AF-related research and therefore provide a new way to discover the scientific foundation of Zhang Zhongjing's herbal formulae.
