One of the most important prognostic factors in LCP disease is the extent of epiphyseal involvement. Magnetic resonance imaging is considered to be the technique of choice for early diagnosis of Legg-Calve-Perthes disease. Gadolinium-enhanced spin-echo MR images were obtained after nonenhanced Tl-weighted(spin-echo) and T2-weighted(gradient-echo) images. Four different areas were identified in the femoral epiphysis(necrosis, regenerative, cartilaginous and normal fatty bone tissue). The histological evolution of LCP is well described by Catterall and others. Comparing their description with our MRI finding, we suggest classification of LCP into three phases: (I) necrosis, (II) regeneration(IIa-early and IIb-late) and (III) reossification and sequale. T2 weighted image was useful in the early stage and Tl weighted image was useful in the later stage for evaluation of involved extent of the disease. With MRI, we think that we can find out the stage of LCP more early and rationally, pathological factors more easily and appropriate time for operation exactly. we believe that MRI is more adequate method to decide the stage of LCP disease.

Verumontanum mucosal gland hyperplasia (VMGH) is a relatively common benign proliferative lesion which was first described by Gagucas et al in 1995. VMGH is usually found in radical prostatectomy or transurethral resection specimens and rarely in needle biopsy specimens. The histologic feature of VMGH is characterized by well-circumscribed proliferation of small glands and thus VMGH may mimic low grade adenocarcinoma. We report a case of VMGH from a 61-year-old man. The lesion coexisted with prostatic adenocarcinoma on radical prostatectomy specimen. The lesion was a well circumscribed microacinar proliferation which was present between the openings of ejaculatory ducts. The acini consisted of two cell layers with inner secretory cuboidal epithelium and outer basal cell. Typically, the lumen contained many corpora amylacea. Nuclear pleomorphism, prominent nucleolus, or mitotic figure was not identified. Because of small gland proliferation of VMGH, this lesion can be confused with other small gland proliferative lesions, such as low grade adenocarcinoma, atypical adenomatous hyperplasia, basal cell hyperplasia, mesonephric hyperplasia, and nephrogenic adenoma. To avoid misdiagnosis of VMGH as carcinoma, one should be familiar with this lesion.

Prostatic carcinoma is the most commonly diagnosed cancer in the United States in men. Prostatic carcinoma in Korean men is uncommon and accounts for less than 1% of total cancer: however, the incidence of prostatic carcinoma is continuously increasing. Several clinicopathologic parameters including stage, Gleason score, and serum PSA level have been widely accepted as well established prognostic factors. To study the clinicopathologic features of prostatic carcinoma in Korean men, 58 cases of prostatic carcinoma, which were diagnosed on radical prostatectony specimens at Asan Medical Center from Jan. 1993 to June 1998 (1993; 3 cases, 1994; 3, 1995; 6, 1996; 12, 1997; 24, 1998; 10), were evaluated. The prostatic carcinomas were divided into three groups according to Gleason score. Tumors with Gleason score 6 or lower, 7, and 8 to 10 were categorized as low-grade, intermediate-grade and high-grade tumor, respectively. The overall mean age of the patients was 62.6 years (range, 4 6~76 years); mean age was 65.4, 62.8 and 61.1 in low, intermediate and high-grade tumor, respectively (p>0.05). The overall mean serum PSA level was 38.6 ng/ml (range, 0.3~276.0 ng/ml); mean serum PSA level was 17.0, 29.0 and 60.9 ng/ml in low, intermediate and high-grade tumor, respectively (p=0.002). The mean T stage was 2.3, 2.4 and 3.1 in low, intermediate and high-grade tumor (p=0.001). The percentage of positive resection margin was 33.3, 50.0 and 91.0 % in low, intermediate and high-grade tumor (p=0.001). The overall presence of prostatic intraepithelial neoplasia (PIN) was 79.3 %; percentage of the presence of PIN was 100, 79.2 and 68.2 % in low, intermediate and high-grade tumor (p>0.05). As reported in the literature, our results indicated that Gleason score was a good predictor of stage and prognosis. The higher Gleason score, the more cases were with positive surgical margins, advanced pathologic stage, and high serum PSA level (p<0.05).

OBJECTIVE： To systematically evaluate the efficacy and safety of rivaroxaban versus low molecular weight heparin in the prevention of venous thromboembolism （VTE） in patients with hip fractures， and to provide evidence-based reference for clinical application. METHODS： Retrieved from Cochrane library， PubMed， Embase， CNKI， VIP and Wanfang database， randomized controlled trials （RCTs） about rivaroxaban （test group） versus low molecular weight heparin （control group） in the prevention of VTE in patients with hip fracture were collected during database establishment to Jun. 2018. After data extraction and quality evaluation with Cochrane system evaluator manual 5.1.0， Meta-analysis was performed by using Rev Man 5.3 statistical software for the incidence of  deep venous thrombosis （DVT）， postoperative discharge， activated partial thromboplastin time （APTT）， prothrombin time （PT） and the incidence of ADR. RESULTS： Totally 8 RCTs were included， involving 949 patients. Results of Meta-analysis showed that compared with low molecular weight heparin， rivaroxaban could significantly decreased the incidence of DVT [RR＝0.55， 95％CI （0.36， 0.83）， P＝0.004]. There was no statistical significance in postoperative discharge [MD＝－0.24， 95％CI （－5.27， 4.8）， P＝0.93]， APTT [MD=0.56， 95％CI （－0.75， 1.86）， P＝0.40]， PT [MD＝0.04， 95％CI（－0.03， 0.11）， P＝0.25] or the incidence of ADR [RR=1.73，95％CI（0.15，20.48）， P＝0.66] between 2 groups. CONCLUSIONS： Rivaroxaban has a better preventive effect on VTE in patients with hip fracture than low molecular weight heparin， and has a similar safety as low molecular weight heparin.

Objective: To assess the implementation and impact of programs carried out by the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases. Methods: Both sociological and epidemiological methods were used to collect qualitative and quantitative data in November and December, 2016 in order to conduct on process and outcome evaluation of the above mentioned objective. In the meantime, case study was also conducted. Results: All the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases were found well implemented across the country, with health education and health promotion, surveillance and safeguard measures in particular. A government-led and inter-sector coordination and communication mechanism had been well established, with more than 16 non-health departments actively involved. 28.7% of the residents living in the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases were aware of the key messages related to chronic diseases. Among the residents, 72.1% of them consumed vegetables and 53.6% consumed fruits daily, with another 86.9% walked at least 10 minutes per day. Over 70% of the patients with hypertension or diabetes reported that they were taken care of by the Community Health Centers, and above 50% of them were under standardized management. Residents, living in the National Demonstration Areas under higher ranking of implementation scores, were more likely to be aware of relevant knowledge on chronic disease control and prevention (OR=6.591, 95%CI: 5.188-8.373), salt reduction (OR=1.352, 95%CI: 1.151-1.589), oil reduction (OR=1.477, 95%CI: 1.249-1.746) and recommendation on physical activities (OR=1.975, 95%CI: 1.623- 2.403). Conclusion: The implementation of programs carried out by the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases had served a local platform for the control and prevention of non-communicable diseases, and thus become an important 'carrier' for chronic disease prevention and control programs in China.
