Prostate cancer is one of the most common malignant tumors in the male urinary system as well as the second leading cause of cancer death in men. Prostate specific antigen (PSA) screening is the main method for the early diagnosis of prostate cancer, but has a low specificity for its detection. In recent years, a variety of tumor markers with high sensitivity and specificity have been found. This review focuses on some of the more promising tumor biomarkers such as prostate cancer antigen 3, early prostate cancer antigen, prostate-specific membrane antigen, alpha-methylacyl-CoA racemase, and vascular endothelial growth factor.

OBJECTIVETo summarize the experience of percutaneous fixation of scaphoid fractures with Herbert screws through volar approach, and provide a reliable and efficient treatment method for scaphoid fractures.

METHODSFrom April 2008 to September 2012,15 patients with scaphoid fractures were treated by percutaneous fixation with Herbert cannulated screws through volar approach including 14 males and 1 female with an average age of 35 years ranging from 25 to 45 years old. Among them, 10 cases were on left side and 5 cases were on right side. Durations from injury to operation ranged from 3 to 10 days with an average of 5 days. All these cases were identified as B2 type according to the Herbert classification based on X-ray and CT scan. In order to assess the function of wrist, all patients were calculated according to Krimmer's score postoperatively.

RESULTSThe follow-up period were from 5 to 18 months with an average of 10 months. At 3 months after operation,X-ray was re-checked every month. All the patients achieved bone union with a mean time of 10 weeks (ranged from 7 to 14 weeks) postoperatively. According to Krimmer's score, 14 cases gained 100 scores as perfect and one case got 90 scores as good. The small volar incision of all patients were union at the first period. No operation complications such as infection and nonunion occurred.

CONCLUSIONPercutaneous fixation with Herbert cannulated screws through volar approach is a reliable and efficient treatment method for scaphoid fractures with small invasion, high bone union rate, and fewer complications.

Objective To investigate the effect of radiotherapy combined with interventional therapy on the changes of vascular endothelial growth factor (VEGF) in patients with advanced cervical cancer.Methods 62 cases of cervical cancer collected in the first people’s hospital of jingzhou city during January 2009 to February 2014 were randomly divided into two groups.The patients in group A were treated with radiotherapy, and the patients in group B were treated with radiotherapy combined with interventional therapy.The level of vascular endothelial growth factor in two groups after treatment was measured by enzyme-linked immunoassay.Results The level of vascular endothelial growth factor of group A was ( 241.77 ±85.86 )μg/L, significantly higher than ( 124.66 ±65.86 )μg/L of group B.The level of vascular endothelial growth factor was related with cervical deterioration degree, tumor stage and lymph nodes metastasis (P<0.05),not with the patient’s age, and the size of the tumors.The level of vascular endothelial growth can reflect the clinical efficacy of patients after therapy (P<0.05).Conclusion Vascular endothelial growth factor level has a close relationship with the degree of deterioration of cervical cancer, tumor staging, lymph node metastasis and the curative effect after the interventional therapy.

Purpose To discuss the clinicopathological features of primary thymic extranodal marginal zone lymphoma of mucosa associated lymphoid tissue (MALT) lymphoma and lymphoepithelial sialadenitis (LESA)-like thymic hyperplasia,their relationship and differential diagnosis.Methods Three cases of thymic MALT lymphoma and one LESA-like thymic hyperplasia were evaluated by HE staining,immunohistochemistry and immunoglobulin (Ig) gene rearrangement technology.Results The symptoms of Sjsgren syndrome were found in the two patients with thymic MALT lymphoma.Microscopically,the normal architecture of thymus was effaced by dense lymphoid infiltration composed predominantly of centrocyte-like and monocytoid B cells with prominent lymphoepithelial lesions.Immunohistochemically,the tumor cells were positive CD20,PAX-5,and BCL-2.The plasma cells showed lambda light chain restriction in one case with prominent plasmacytoid differentiation.In LESA-like thymic hyperplasia,the normal lobular architecture of thymus was generally reserved and abundant lymphoid tissue containing lymphoid follicles was seen with prominent lymphoepithelial lesions in expanding islands of thymic epithelial cells and epithelium lining the cysts,but a monocytoid B-cell population was absent.Immunohistochemically,a mixed B-cell and T-cell population was identified.A monoclonal rearrangement of the Ig gene was detected in all three thymic MALT lymphomas but not in the case of LESA-like hyperplasia.Conclusion Primary thymic MALT lymphoma and LESA-like thymic hyperplasia are both rare lymphoid proliferative lesions and the two lesions have overlapping histological and immunohistochemical features.A combination of genetic rearrangement and analysis of the differential points is helpful to distinguish between them.

Objective To explore the method to carry out epidemiological investigation of chronic kidney disease (CKD) in rural area surrounding the Tarim Basin, and to elucidate the prevalence and risk factors associated with CKD among the Uygur adults in Moyu county. Methods A total of 1650 residents (age >18 years) from 15 villages in 3 rural town of Moyu county were randomly selected by using a stratified, multistage sampling. All the residents were interviewed and received physical examination and tested for random spot urine of albumin to creatinine ratio (ACR). Estimated glomerular filtration rate (eGFR) was calculated by modified factors of CKD were examined. Results Valid data of 1552 subjects were enrolled in the study. After the adjustment of age and gender component, the prevalence of albuminuria and reduced eGFR was 4.5% (95% CI 4.4-4.6) and 1.4% (95% CI 1.4-1.5) respectively. Approximately 5.4% subjects had at least one indicator of kidney damage. Age and hypertension were independently associated with CKD. Conclusions Experience and method of epidemiology investigation of CKD in the rural areas of Uygur are obtained through this study. The prevalence of CKD is 5.4% and the awareness is 12.5% in the Uygur adults of Moyu county. Independent risk factors associated with CKD are hypertension and age.

The teaching status of Molecular Pharmacognosy in 28 institutions in China was investigated by questionnaire and the survey data was analyzed by SPSS. Research contents included course beginning years, majors, class hours, characteristics of the course, teaching ways, the theory and practice contents, evaluation modes, selection of teaching material, teaching achievements, teachers and so on for undergraduates and graduates. Research results showed that with 20 years' development, Molecular Pharmacognosy had been offered for both undergraduate and graduate students in at least 20 colleges and universities and Molecular Pharmacognosy education in China showed good development momentum. At the same time, to promote the development of Molecular Pharmacognosy further, investment for it should be increased and practical teaching condition should be improved.
