Clinical practice teaching is the deepening and continuity of school education , which is an important part of medical education. This paper aims to analyze the current situation and problems as to the teaching management during clinical training of full-time clinical major students, and put forward the corresponding countermeasures . The clinical practice teaching management and the clinical intern training quality can be significantly improved by establishing normative practice teaching management sys-tem, innovating teaching management mechanism, and correct treatment of the contradiction between clin-ical practice, employment and taking part in the entrance exams for postgraduate schools.

Objective To evaluate the effect of plastic surgery for scar contracture after hand burn.Methods Clinical treatment data of 56 patients with scar contracture after hand burn was collected from December 2011 to December 2016.Different surgery methods were adopted to treat the scar contracture after hand burn according to different degree,different sites and different range.Results All cases were operated successfully,and the appearance and function of the hands were almost recovered during the 6 months' follow-up,without contracture again.Conclusion Appropriate surgical programs should be used in scar contracture with different parts and degrees,and reasonable postoperative rehabilitation can improve the function and appearance of hands better,which can avoid secondum contracture.

AIM: To explore the effect of exogenous carbon monoxide (CO) on the hypoxic pulmonary arterial hypertension in the rat. METHODS: 60 rats were randomly divided into 5 groups: Normal group\, hypoxic group\, Hermin group\, Znpp group and CO group. HO-1 activity was examined by spectrophotometer and lung tissues was stained by immunohistochemical method. HO-1 mRNA level was tested by reverse transcriptase polymerase chain reaction (RT-PCR). RESULTS: (1) The pulmonary arterial pressure (18.52?3.24 mmHg) in CO group was higher than anoxic group and lower than hypoxic group (P

Objective To compare the efficacy and adverse effects of bortezomib+adriamycin+dexamethasone (PAD) and vincristine + adriamycin + dexamethasone (VAD) regimens in untreated multiple myeloma (MM). Methods There were 26 and 28 new diagnosed MM patients in PAD and VAD groups. Both clinical effects and adverse effects were observed. Patients accepted VAD or PAD regimens for 2-4 cycles and followed up for 7-27 months. Results There were 10, 5 and 11 patients accepted 2, 3 and 4 cycles in PAD group, and 6, 11 and 11 in VAD group. In PAD group, there were 2, 14, 9, 1 and 0patients achieved complete remission (CR), very good partial remission (VGPR), partial remission (PR),stable disease (SD) and progressive disease (PD); in VAD group, the number were 0, 4, 12, 10 and 2.The rate of patients who achieved good efficacy (CR+VGPR) in PAD group was 61.5%, which was higher than that in VAD group (14.3%).The incidences of infection and gastrointestinal symptoms were similar in the two groups, while the incidences of peripheral neuropathy, thrombosis and Herpes Zoster infection in PAD group were higher than those in VAD group. Conclusions Compared with the conventional VAD chemotherapy, PAD may improve CR and VGPR rates in new diagnosed MM, while it may bring more and severer toxicities in peripheral neuropathy, thrombosis and Herpes Zoster infection. Preventive medical care is necessary in PAD protocol.

Objective: To evaluate clinical outcomes of autologous and allogeneic peripheral blood stem cell transplantation (PBSCT) for aggressive peripheral T-cell lymphoma (PTCL). Methods: From June 2007 to June 2017, clinical data of PTCL patients who underwent PBSCT were assessed retrospectively. Results: Among 41 patients, 30 was male, 11 female, and median age was 38(13-57) years old. Seventeen patients with autologous PBSCT (auto-PBSCT) and 24 patients with allogeneic PBSCT (allo-PBSCT) were enrolled in this study. Eight patients (8/17, 47.1%) in auto-PBSCT group were ALK positive anaplastic large cell lymphoma (ALCL), 7 patients (7/24, 29.2%) with NK/T cell lymphoma and 9 patients (9/24, 37.5%) with PTCL-unspecified (PTCL-U) in allo-PBSCT group (P=0.035). There were 58.8% patients (10/17) in complete response (CR) status and 11.8% (2/17) in progression disease (PD) status before transplantation in auto-PBSCT group, and 8.3% (2/24) in CR status and 45.8% (11/24) in PD status before transplantation in allo-PBSCT group (P=0.026). The 2-years cumulative overall survival (OS) were (64.0±10.8)% and (53.5±9.7)% for auto-PBSCT and allo-PBSCT respectively (P=0.543). The 2-years cumulative disease-free survival (DFS) were (57.1±12.4)% and (53.5±10.6)% for auto-PBSCT and allo-PBSCT respectively (P=0.701). In patients with dead outcomes after PBSCT, 83.3% (5/6) of death cause was relapse in auto-PBSCT and 41.7% (5/12) of death cause was relapse in allo-PBSCT. Conclusion Both auto-PBSCT and allo-PBSCT were effective for PTCL. Allo-PBSCT maybe was better than auto-PBSCT for high-risk PTCL with poor prognosis.

Objective: To study the expression of miRNA-181a in acute myeloid leukemia (AML) patients with normal karyotype to probe its prognosis significance. Methods: The expression level of miRNA-181a in bone marrow mononuclear cells of 120 de novo AML patients with normal karyotype was detected by real time fluorescence quantitative PCR. The direct sequencing method was used to detect IDH1, IDH2, NPM1, FLT3-ITD, DNMT3A and CEBPα mutations in CN-AML patients after PCR. The relationship between miRNA-181a expression and gene mutation, the clinical parameters and prognosis were analyzed. Results: The rates of overall surviva1 (OS) in high expression and low expression groups were 25.0 months and 15.0 months, respectively (P<0.05) . Relapse free survival (RFS) in high expression and low expression groups were 21.4 months and 11.2 months, respectively (P<0.05) . Significantly higher level hemoglobin, complete remission rate and proportion of wild type NPM1 expression in the high expression of miRNA-181a group were observed when compared with the lower expression of miRNA-181a group (P<0.05) . Multivariate Cox regression analysis showed miRNA-181a overexpression was an independent prognostic factor for CN-AML (HR=2.219, 95%CI 1.601~2.432, P=0.018) . Conclusion Higher expression of miRNA-181a was a good prognostic factor independent of clinical parameters and high frequency gene mutations, which implicated that the miRNA-181a expression level could be used as an important prognostic indicator of AML patients with normal karyotype.

Nephroptosis,a rare condition in urology,often results from inadequate support of the kidney's perinephric fat structures,leading to excessive renal mobility.It typically occurs in lean,tall,young females.Some cases manifest with abdominal pain and renal dysfunction.Open nephropexy,laparoscopic nephropexy and percutaneous nephropexy are all effective methods in the treatment of nephroptosis,among which percutaneous nephropexy is associated with less trauma and lower costs.Modifications to percutaneous nephropexy by the authors'team are also introduced mentioned in this article.

To implement the strategy of healthy China and promote the construction of "new medicine science", it is urgent to focus on new needs and challenges to advance the reform of medical education curricula in China. Using literature research methods, we summarize the process of modern medical education curriculum reforms in the United States, and discuss the main features of the third-round reforms—introducing the concept of value-based medicine, offering health systems science courses, and promoting the curriculum system reform from the perspectives of learning time, curriculum integration, and learning methods. Based on these features, we put forward the enlightenment for the reform of medical education curricula in China.

With the increasing popularity of chest spiral CT screening, the detection rate of lung cancer in China is increasing. According to the characteristics of lung cancer in China and the progress of lung cancer researches at home and abroad, Chinese Medical Association guidelines for clinical diagnosis and treatment of lung cancer are updated once a year. It is of great guiding significance to standardize and improve the clinical diagnosis and treatment of lung cancer for thoracic surgeons. The surgical diagnosis and treatment of lung cancer in the guidelines mainly include: (1) surgical treatment of stage Ⅰ-Ⅱ non-small cell lung cancer (NSCLC); (2) surgical treatment of resectable stage Ⅲ NSCLC; (3) surgical treatment of multiple primary lung cancer; and (4) surgical treatment of locally resectable small cell lung cancer. Based on the Chinese Medical Association guidelines for clinical diagnosis and treatment of lung cancer (2019 edition), this paper interprets the hot issues related to the surgical treatment of lung cancer.
