[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 diagnostic value of HR -HPV combined with TCT in the diagnosis of cervical cancer and precancerous lesion.Methods 1 198 cervical specimens were selected for the study.The results of HR -HPV detection and TCT detection were analyzed,with the pathological results as the gold standard,the diag-nostic value of HR -HPV and TCT in the diagnosis of cervical cancer and precancerous lesion were discussed. Results With increasing pathological grade,TCT positive rate increased gradually,there was a correlation between them(r =0.629,P <0.05).With increasing pathological grade,HR -HPV positive rate increased gradually,there was a correlation between them(r =0.684,P <0.05).The sensitivity of HR -HPV combined with TCT in the differ-ential diagnosis of cervical cancer,precancerous lesions was 100.00%,specificity was 79.64%,missed diagnosis rate was 0.00%,the misdiagnosis rate was 20.36%.Conclusion HR -HPV combined with TCT examination has high clinical value in the diagnosis of cervical cancer and precancerous lesions.

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 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.

Objective To investigate the loss of heterozygosity (LOH) of 3p D3S1300 and D3S1289 loci of plasma DNA of lung cancer (LC) patients and evaluate its value for a tumor marker of lung cancer.Methods Two microsatellite markers,D3S1300 and D3S1289,were analyzed by PCR and silver staining to investigate LOH of the plasma DNA and cancer tissue DNA from 69 cases of primary lung cancer,and the plasma DNA from 40 control subjects.Results The percentages of D3S1300 LOH detected in the tumor tissue and plasma DNA of LC patients were 40.6% and 29.0% respectively,while the percentages of D3S1289 LOH were 31.9% and 24.6% respectively.In contrast,only 2 cases of D3S1300 LOH and 3 cases of D3S1289 LOH were found in plasma DNA of control group (P

Objective To investigate the satisfaction degree with nursing for discharged patients by telephone interview,and understand the nursing quality improvement during hospitalization of patients.Methods In January and December 2011,24 clinical departments were selected as the research object,10 patients were selected from each department.The questionnaires of satisfaction degree with nursing were adopted to investigate the satisfaction degree of patients by telephone interview.The difference of satisfaction degree with nursing were compared between January and December 2011.Results Compared with the results of January,there were statistical differences in overall mean score of satisfaction degree and the dimensions of service attitude,knowledge information,ward management and working ability.While the means of dimensions of basic nursing care and care-taking patient were in high levels.Conclusions The method of telephone interview to investigate the satisfaction degree of discharged patients is direct,real and objective.It is convenient for the hospital to understand the nursing quality and existing problems during hospitalization of patients,and offers scientific way for continuous improvement of nursing service.

Objective To investigate the anti-rotavirus effect of Gegen Qinlian decoction on rotavirus (RV)-inducing diarrhea neonatal mice model, and provide evidences for pharmacological and pharmacodynamic studies. Methods Neonatal diarrhea mice model of Kunming family infected with RV-Wa was developed. Symptom, diarrhea ratio and severity level, histological changes of neonatal mice’s small intestine and lung was assessed after Gegen Qinlian decoction (0.78 g/kg) treatment. Results Diarrhea ratio, diarrhea severity level, histological changes of neonatal mice’s small intestine and lung were obviously decreased after Gegen Qinlian decoction (0.78 g/kg) treatment. Conclusion Gegen Qinlian decoction has anti-rotavirus effect on RV induced diarrhea.

Aim The aim of the present study is to in-vestigate the effect of the specific antagonist NVP-AAM077 and Ro25-6981 of NMDA receptor subunit NR2A and NR2B on global cerebral ischemia-induced neuronal injury in the CA1 region. Methods Male C57BL/6 mice subjected to global ischemia by the three-vessel occlusion( 3-VO) method,were divided into four groups: sham-operated group,ischemia/reperfusion control group,NVP-AAM077 treatment group,and Ro25-6981 treatment group. Hippocampal sections were processed for Fluoro-Jade B staining to detect degenerating neurons and for Nissl staining to identify surviving neurons. The expression of brain derived neurotrophic factor( BDNF) were measured by Western blot. Results ① Transient brain ischemia induced selective and delayed neuron death in the CA1 region of the hippocampus at 12-minute ischemia after reperfusion 3 days. NR2A subtype specific antagonist NVP-AAM077 enhanced neuronal death after transient global ischemia ( P

Object To set up the quantitative method for determining the puerarin in Gegen Qinlian Decoction (GQD) by RP-HPLC and to study the change of puerarin contents in various combinations of GQD. Methods L 8(2 7) orthogonal design and statistic analysis (SPSS 10.0) were used, the puerarin contents in the samples were determined by HPLC. Results Influence of Radix Scutellaria, Rhizoma Coptidis and Radix Glycyrrhizae Preparata on the puerarin content in GQD was insignificant. And interactions between two of three were insignificant too. In this experiment, puperarin in the sedimentation was found in the compatible decoction of Rhizoma Coptidis and Radix Puerariae. Conclusion The puerarin content is not markedly influenced by Radix Scutellaria, Rhizoma Coptidis and Radix Glycyrrhizae Preparata. Maybe, the change of pH is relevant to the sedimentation in the compatible decoction contained Rhizoma Coptidis. and Radix Puerariae
