[Summary] Radical prostatectomy, external beam radiation and active surveillance are the main treatments for localized prostate cancer. However, many patients are difficult to accept the psychological burden of active surveillance and the distress caused by potential side effects of radical therapy, including incontinence and erectile dysfunction, which make them limited. With the development of minimally invasive techniques, such as brachytherapy, cryoablation, high-intensity focused ultrasound, photodynamic therapy, and irreversible electroporation, novel procedures are playing an increasingly important role in the treatment of localized prostate cancer with their effective, minimally invasive, and safe advantages. This article mainly reviewed the above several minimally invasive treatment methods.

Objective To explore the application of scene type trace method in physiology teach-ing reform. Methods 2009 grade clinical medicine students in Zunyi Medical College were randomly di-vided into two groups:control group (n=111) and experiment group (n=108). Students in control group were taught by traditional teaching method while those in experimented group by scene type trace method. According to the questionnaire survey and the final exam statistical analysis,the effects of teach-ing were evaluated. SPSS 15.0 software was used to do statistical analysis. Qualitative data were analyzed by chi-square test of completely randomized design and two sets of frequency distribution while quantita-tive data by independent samples t test. P<0.05 means that difference is statistically significant. Results There were statistically differences in satisfaction degree of two teaching methods. More students were sat-isfied with scene type trace method than traditional teaching method. Final exam achievement in scene type trace method group(79.90±14.25,90.74%)were higher than that in the traditional teaching method group(72.35±17.09,83.78%). Conclusions Physiology teaching scene type trace method is helpful to improve the students' learning initiative and significantly improve students' learning achieve-ment.

Melanoma is the most aggressive and lethal malignant tumor in skin cancers. Operation resection is used to treat stageⅠ/Ⅱmelanomas, but traditional operation, chemotherapy, and radiotherapy inflicts adverse effects on late-stage melanomas. StageⅢ/Ⅳmelanomas are some of the most ineffectively treated tumors with poor prognosis. As a cancer treatment, targeted immunotherapy in-hibits negative regulatory factors and enhances systemic anti-tumor immune effects. Radiotherapy not only kills tumor cells, but also en-hances systemic immune responses. Recent studies showed that targeted immunotherapy combined with radiotherapy can promote con-trol on local and distant tumors and prolong overall survival. The synergistic effects of these two therapies are superior to a single thera-py. This review summarized the progress on these research fields.

Objective To explore the effects of quercetin and quercetin in combination with cisplatin on adhesion, migration and invasion of HeLa cells. Methods Adhesion, migration and invasion of HeLa cells treated with quercetin and quercetin in combination with cisplatin were measured by adhesion assay, wound healing assay, and transwell chamber method respectively. Results The results showed that quercetin and quercetin in combination with cisplatin could inhibit adhesion, migration and invasion of HeLa cells. The adhesive ratio, migration rate and the invasiveness were negatively proportional to concentration of quercetin and quercetin in combination with cisplatin. With increasing concentration of quercetin from 20 to 80 μmol/L, the adhesive ratio decreased from ( 82. 2±1. 5 ) % to ( 48. 4±1. 1 ) % ; the migration rote decreased from (7.26±0. 20) μm/h to (3.78±0. 64) μm/h; the invasiveness decreased from ( 124. 3± 1. 5) piece to (90. 7±2. 1 ) piece(P <0. 05). In quercetin and quereetin in combination with 10 μmol/L cisplatin treatment group, with quercetin concentration increasing from 20 to 80 μmol/L, the adhesive ratio decreased from (42. 6±1. 2) % to ( 27. 5±1. 7 ) %, the migration rate decreased from ( 2. 20±0. 33) μm/h to (0.72±0. 19) μm/h and the invasiveness decreased from (78.7±2.5) piece to (44.0±4.0) piece (P < 0. 05 ). Compared with the quercetin groups, querectin in combination with cisplatin groups had significantly higher inhibitory effects ( P < 0. 05 ). Conclusions Quercetin and quercetin in combination with cisplatin can inhibit adhesion and migration and invasion of HeLa cells. Quercetin can enhance the inhibitory effect of cisplatin on HeLa cell adhesion, migration and invasion.

Object To set up the quantitative method of baicalin in Gegen Qinlian Decoction (GQD) by RP HPLC and to determine the change of baicalin contents in decoctions prepared from various combinations of GQD. Methods By L 8(2 7) orthogonal design and statistics analysis (SPSS10 0), eight decoctions with Radix Scutellariae either alone or incombination with one or more of the other three components were prepared or analyzed. Contents of baicalin in them were determined by RP HPLC. Results It was significant (P0 05) and interactions between two of three were insignificant either. In this experiment, the sedimentation was found in the decoctions contained Radix Scutellariae and Rhizoma Coptidis. Conclusion The content of baicalin is reduced by Radix Puerariae and Rhizoma Coptidis, The resolution of baicalin is not increased by Radix Glycyrrhizae Preparata. Maybe the change of pH leads to the sedimentation in decoctions contained Radix Scutellariae and Rhizoma Coptidis.

Objective To evaluate the diagnostic value of the low field MRCP in obstructive jaundice by comparing its result with that of US and CT. Methods 55 cases of obstruction jaundice patients proved by clinical diagnosis were studied and compared the collected original diagnosis results by low filde MRCP with US and CT.Results Of 55 cases of obstructive jaundice, 30 were cholelithiasis ,21 were tumors and 4 belonged to the other type. The accuracy of MRCP for defining the site of obstruction was 100%. The accuracy for identifying the cause of obstruction was 81.8%.Conclusion The low filde MRCP can accurately define the obstructive site in biliary obstructive disease .When used together with 2D single-shot breath-hold MRCP , T 2WI, T 1WI and 3D-FSE MRCP shows high accuracy and sensitivity in diagnosing obstructive jaundice.

Objective: To explore the effect of suberoylanilide hydroxamic acid (SAHA) improving cardiac hypertrophy via inhibiting histone deacetylases (HDAC) in experimental mice and to provide a new idea for prevention and treatment of cardiac hypertrophy. Methods: Cardiac hypertrophy mice model was established by thoracic aorta ligation. A total of 60 Kunming mice were randomly divided into 4 groups: Normal control group, Sham operation group, Cardiac hypertrophy (CH) group and CH+SAHA group. There were 6 mice used in each group. Myocardial cell morphology was observed by HE staining, cardiac function was assessed by echocardiography, mRNA and protein expressions of HDAC5 (the isoform of HDAC) and β-MHC were examined by RT-PCR and Western blot analysis. Results: The mice in CH group had myocardial cell hypertrophy, disordered arrangement and hyperchromatic nucleus. Compared with Sham operation group, CH group showed decreased left ventricular end diastolic diameter (LVEDD), left ventricular end diastolic volume (LVEDV) and increased thickness of inter-ventricular septum (IVS), allP<0.05; CH group presented elevated mRNA and protein expressions of HDAC5 and β-MHC,P<0.05. SAHA obviously decreased HDAC5 expression, down regulated cardiac hypertrophy related β-MHC gene expression, improved cardiac function and hypertrophy, all P<0.05. Conclusion: HDAC were involved in myocardial hypertrophy; SAHA could inhibit HDAC expression and therefore,improved myocardial hypertrophy in experimental mice.
