Lower urinary tract symptoms (LUTS) resulting from benign prostatic hyperplasia (BPH) obviously impair the quality of life of middle-aged and elderly men. Current management of BPH includes wait-and-watch, medical therapy, and conventional surgery. As a new approach, minimally invasive surgery has been playing an increasingly important role in the management of BPH, with potential advantages of less operative trauma, quicker recovery, lower risk of postoperative complications and higher quality of life. This review mainly discusses prostatic urethral lift (Urolift® System), transurethral water vapor therapy (Rezūm® System) and robot-guided high-energy water ablation (PROCEPT Aquablation™ System).

Objective: To quantitatively study the incidental extra-cardiac ifndings (ECFs) by coronary computed tomography angiography (CCTA) in patients with suspected coronary artery disease (CAD) in order to better recognize those lesions in clinical practice.
Methods: A total of 1169 suspected CAD patients received CCTA in our hospital from 2011-06 to 2013-03 and 1030 patients were enrolled in this study. There were 589 in-patients, 441 out-patients and 549 patients≥60 years of age,481 patients < 60 years of age. 3 physicians evaluated the incidental ECFs in the full ifeld of view (FOV) in different window level and window width for lung, mediastinum, thorax and upper abdominal areas. Clinical relevance of ECFs were classiifed by corresponding scores. Score 1, the patients with severe lesion need immediate treatment, score 2, the lesion with clinical and prognostic signiifcance and score 3, the ifnding without clinical signiifcance.
Results: There were 197/1030 (19.1%) patients having 224 ECFs and 27 (2.6%) patients having 2 ECFs; 90/1030 (8.7%) patients having 106 signiifcant lesions including 3 (0.3%) of lung cancer and 8 (0.8%) of pulmonary embolism; 107 patients with 118 lesions without signiifcance. ECFs were found in 114/589 (19.4%) in-patients and in 83/441 (18.8%) out-patients, P>0.05; 76/481 (15.8%) of patients < 60 years of age and 121/549 (22.0%) of patients≥60 years,P<0.05.
Conclusion: Unexpected ECFs detection rate was 19.1% in patients undergoing CCTA without further radiation exposure by reconstruction with the full FOV setting, and 8.7% of ECFs had clinical signiifcance. Radiologists should routinely analyze the extra-cardiac organs in CCTA.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

Objective To analyse effects of the serum levels of thyroid peroxidase antibodies (TPOAb) on antithyroid drugs (ATD) treatment in patients with incipient Graves disease (GD). Methods A total of 121 patients with incipient GD, who were used anti thyroid drugs for 12 months, were included in this study. Patients were dvided into two groups:TPOAb negative group (TPOAb≤35 IU/mL, n=49) and TPOAb positive group (TPOAb>35 IU/mL, n=72). According to the degree of TPOAb drops the TPOAb positive group was sub-divided into low level positive group (35 IU/mL1 000 IU/mL, n=20). The ATD total dosage for 12 months and thyroid-stimulating hormone (TSH), which returned to normal rate after treatment of 3, 6 and 12 months, were compared between groups. Results ATD total dose was lower in TPOAb positive group (1 743.82±265.38) mg than that of negative group (1 889.18 ±125.51) mg. The ATD total dosages were (1 759.71±230.29) mg, (1 793.75±299.02) mg, (1 731.54± 236.44) mg and (1 710.00 ± 290.73) mg for low level TPOAb positive group, medium level TPOAb positive group, high level TPOAb positive group, and very high level TPOAb positive group respectively. The recovering ratio of TSH was significantly higher in TPOAb positive group than that of TPOAb negative group after 3-month treatment (P<0.05). Conclusion TPOAb positive serum can lead to shorten the course of ATD treatment and reduce the total amount of ATD treatment in GD patients.

Objective To observe the effect of light emitting diode (LED) red light irradiation on serum lipid in experimental hyperlipidemia rats. Methods 36 healthy male Sprague-Dawley rats were randomly divided into normal control group (n=12) and hyperlipidemic model group (n=24). The normal group was fed with normal diet while the hyperlipidemic model group with fat-rich forage for 6 weeks. The hyperlipidemic model group rats were randomly divided into the hyperlipidemic control group (n=12) and LED treatment group (n=12), and the latter accepted LED red light irradiation for 28 d. The levels of serum lipid including total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C), and the activities of lipoproteinesterase (LPL) and hepatic lipase (HL) were detected with biochemical assay. The expression of 3-hydroxy-3-methylglutaryl coenzyme A reducase (HMG-CR) of hepatic tissue were measured with immunohistochemical staining. Results Compared with the hyperlipidemic control group, the levels of serum TC, TG and LDL-C decreased while the serum HDL-C increased significantly in the LED treatment group (P<0.01) after treated with LED. The levels of LPL and HL in serum increased (P<0.01) while the activity of HMG-CR decreased (P<0.05). Conclusion LED red light irradiation might play a regulating effect on serum lipid by enhancing the activities of LPL and HL and inhibiting the expression of HMG-CR to interfere the metabolism of TC, TG, LDL-C and HDL-C.

Objective To study the clinic effects and safety of budesonide suspension combined with tubertaline solution for nebulization therapy on infantile asthma.Methods Seventy-five cases with asthma were divided into 3 groups randomly,double-blinded and controlled,each group having 25 cases.Group A inhaling tubertaline solution(bricanyl),while group B inhaling pulmicort respules combined with bricanyl,group C inhaling budesonide suspension(pulmicort respules)only.Results In group A,16 cases was cure,3 cases was markedly improved,6 cases was failure,the total efficacy rate was 76 percent.In group B,22 cases was cure,2 cases was markedly improved,1 case failed,the total efficacy rate was 96 percent.While in group C,14 cases was cure,4 cases was markedly improved,7 cases failed,the total efficacy rate was 72 percent.The difference of efficacy rate between group A and group B was significant(P0.05).Conclusion Pulmicort respules combined with bricanyl for nebulising inhalation is effective and safety on infantile asthma and its effect is better than inhaling bude-sonide or tubertaline only.

In this study, modification technology by surface coating was used to improve the flowability of powder of Chinese herbs extracts. Seven kinds of powder of Chinese herbs extracts were coated with 1% silica nanoparticles using an under-driven Comil. The powder characteristics tester was used to evaluate the flowability of uncoated and coated powders. Surface morphology and particle size distribution of powders were compared by scanning electron microscope (SEM) and optical microscope. The powder hygroscopicity was also investigated. The results showed that, after modification, angle of repose, angle of spatula, compressibility and adhesiveness extremely decreased, and flowability index substantially increased, the powder flowability was significantly improved, especially Gegen and Dahuang extracts powders. Scanning electron microscopy images showed the distribution of silica nanoparticles on the host drug particle surfaces. There were no remarkable changes in the particle size distribution and hygroscopicity of all powders after coating. Therefore, Comilling for surface coating modification technology was an effective method to improve the flowability of Chinese herbs extracts and suggested a possible way forward to enhance the quality of Chinese drugs pharmaceutics in their study and manufacture.

Objective To investigate the effect of gender differences in distal femoral geometry on the clinical outcomes of total knee arthroplasty (TKA). Methods From March 2003 to October 2006, 213 cases with 294 osteoarthritic knees who had underwent primary TKA were involved in the study. The study included 87 men (118 knees) and 126 women (176 knees) who had a mean age of 64.4 years. All the cases were assessed with the knee-rating system of Knee Society, the knee range of flexion (ROF), corrected posterior offset (PCO) and anterior condylar offset (ACO) based on sex. Results Each patient had a Minimum of 2 years follow-up. The preoperative Knee Society scores and ROF, the two-year postoperative changes of stability scores and walking ability had no differences between the two groups. While greater improvements of postoperative pain scores and stair-climbing ability were seen in male. Men had better intraoperative ROF than women had ones, but there were no gender differences with regard to the two-year postoperative improvement of ROF. Corrected PCO decreased more markedly in female than in male. Corrected ACO decreased equally in female and male. The difference in the posterior condylar offset after TKA was statistically correlated with the change in pain scores, stair climbing ability and intraoperative ROF, respectively. Conclusion Male had a better outcome than female did after TKA. Femoral components which designed in the light of Caucasian anatomic characteristics couldn't match the native anatomy of distal femurs of Chinese female. Sexual dimorphism in humans and anatomic variations in various ethnic groups should be seriously considered in total knee prosthesis design.

Tumor metastasis is one of the important biological characteristics of malignant tumor,which is closely related with the prognosis of the cancer patients.High expression of ADAM8 in varieties of tumors was revealed in many recent studies,and such aberrant expression played a crucial role in regulating of tumor metastasis.Studies showed that overexpression of ADAM8 attenuated the intercellular adhesion effect,promoted tumor angiogenesis,and enhanced the degradation of ECM as well as the releasing of cytokines.Therefore,suppression of ADAM8 may lead to inhibition of tumor metastasis,which makes ADAM8 a particular attractive target as it can be used as a prognostic indicator and a potential therapeutic target of malignant tumor.A review about the relations between ADAM8 protein′s abnormal expression and tumor occurrence was discussed in this paper,also include discussion about the mechanisms of ADAM8 protein′s disorder-induced tumor formation,as well as therapeutic strategies based on ADAM8-targeted,which may provide references for follow-up research and clinical treatment.

Objective: To investigate the relationship of clinicopathological characteristics with neoadjuvant chemotherapeutic efficacy and prognosis of inflammatory breast cancer (IBC) patients. Methods: Medical records of 81 patients who underwent neoadjuvant chemotherapy for IBC in Tianjin Medical University Cancer Institute and Hospital between January 2010 and December 2013, were retrospectively analyzed. Clinicopathological features, response to neoadjuvant chemotherapy, and prognostic factors were studied by univariate and multivariate analyses. Results: The 3-year overall survival rate (OS) and disease-free survival rate (DFS) of patients were 53.1％ and 37.0％, respectively. The pathologic complete response (pCR) rate of patients after accepting neoadjuvant chemotherapy was 13.6％ (11/81). Statistically significant association was observed between pCR and pathological types in IBC (P<0.05). However,pCR had no benefit in improving the clinical outcomes of IBC patients (P>0.05). Preoperative lymph node stage was an independent prognostic factor of overall survival (OS) and disease- free survival (DFS) in IBC patients (P<0.05). Neoadjuvant chemotherapy and lymph vessel tumor emboli were independent factors of DFS (all P<0.05). Conclusion: Clinicopathological characteristics of IBC patients affected chemosensitivity. We could predict the prognosis of these patients by preoperative lymph node stage and lymph vessel tumor emboli and select chemotherapy to achieve the best curative effect.
