Objective:To analyze the clinical features, treatment efficacy and prognosis of cavernous lymphangioma.Methods:The clinical manifestations, laboratory findings, imaging examinations and treatment of 8 patients with pathology-diagnosed cavernous lymphangioma admitted in Peking Union Medical College Hospital from January 1990 to July 2020 were retrospectively analyzed.Results:All the patients were female. The onset age ranged from 0 to 58 years, with a course of 24 (5,78) months. There were 2 cases of abdominal mass, 2 cases of axillary mass, 1 case of neck mass, 1 case of inguinal mass, 1 case of mandibular mass and 1 case of pleural and peritoneal effusion. Seven cases had adult onset and 1 case had congenital onset. Two patients had had history of surgery adjacent to lesion sites. Contrast-enhanced CT scan showed a low-density round mass with no significant enhancement in 5 patients. Seven patients underwent complete resection of the mass, 1 patient received partial resection and intervention with medium-chain fatty-acid diet. During the follow-up, 4 patients were stable after 3.5 (1.3-17.8) years, while 2 patients relapsed 1 and 13 year after surgery, respectively. Additionally, one patient was diagnosed with Bowen disease.Conclusion:Cavernous lymphangioma can be congenital or acquired and usually occurs in female. The body mass is the common clinical manifestation; and surgery is the most common treatment, but it is prone to relapse and requires long-term follow-up.

To study the chemical constituents of Veratrum dahuricum (Turcz.) Loes. f., a new aurone glycoside named as (Z)-7, 4'-dimethoxy-6-hydroxyl-aurone-4-O-β-glucopyranoside was isolated from the 95% ethanol extracts of the rhizomes and roots of Veratrum dahuricum (Turcz.) Loes. f. by repeated column chromatography on silica gel and recrystallization. Its structure was established by extensive spectroscopic analyses, and its cytotoxicities against HepG-2, MCF7 and A549 cell lines were measured in vitro.

International medical community has seen the prevail of outpatient teaching for medical students in recent years. A student-centered and faculty-run teaching clinic was set up based on current outpatient resources in 2008 by Division of General Internal Medicine (DGIM) in Peking Union Medical College Hospital (PUMCH). We concluded that teaching clinic was an effective teaching mode for medical students to improve clinical skills, diagnostic proficiency and health-care professionalism in internal medicine.

Objective To discuss the electrocardiogram(EKG)positioning method to the guiding role of determining the pipe length and the accuracy of operative localization in central venous catheterization procedure. Methods Chose 32 cases of tumor patients who had center venipunture.Use the catheter taken EKG data when cath-etering,and then given validation using postoperative chest X -ray or fluoroscopy.Judgment the sensitivity,specificity and disposable catheters success rate of the EKG positioning method.Results In the 32 cases of cancer patients, 30 patients had characteristic P waves,when the chest X -ray confirmed the superior vena cava or the junction with the right atrium,one case into the right atrium,when one case of non -P -wave in the subclavian after intravenous discounts tune into the tube after it confirmed the superior vena cava.Conclusion EKG positioning method with high accuracy in the deep venous catheter in the catheter tip positioning applications.The clinical applications are feasible.

Objective To review the feedback from trainees and trainers of interactive clinical skill training workshop for general practice.Methods An interactive clinical training workshop was held on October,2014,medical staff from 17 provinces or municipalities attended the workshop.Feedback from 86 trainees was collected by questionnaire survey,while the feedback from 12 trainers was collected by focus group.Results Total 86 questionnaires were collected from trainees with a response rate of 100％.The average working year of trainees was 15.6 ; 38.4％ of them were general practitioners in community health centers; and most of them had no similar trainings before.Among 86 trainees,70 (81.4％) thought that the training contents were relevant to their daily work,76 (88.4％) thought that workshop was good method for the training.More than 55.0％ trainees told that the training contents met their expectation ; 76 (88.4％) thought that the workshop was well conducted in general,68 (79.1％) were willing to participate similar training workshops in the future.However,the contents probably need similar training advised by the trainers in the questionnaire were not agreed by trainees.The trainers thought the width and depth of training contents should be modified according to the trainees' level.Basic knowledge,basic clinical skill and common diseases should be emphasized ; and the concept of general practice and indications of referral were among the important but difficult parts in the training.For an interactive clinical skill training,teaching materials preparation,lacale control and local teaching facilities were all important.Conclusions Clinical skill training is an important part of general practitioners' training,and workshop is an effective way for training.The training contentd should be more closer to the daily work of general practitioners.

Objective To evaluate the effects of induction chemotherapy plus radiotherapy (ICRT) and concurrent chemotherapy plus radiotherapy (CCRT) for Stage Ⅱ -Ⅲ non-small cell lung carcinoma (NSCLC) . Methods From July 19% to July 1999, 64 patients with Stage Ⅱ -Ⅲ NSCLC were randomized into two groups: ICRT group (32 patients) induction chemotherapy with DDP( 100mg/m2,dl) and VP-16 (100mg/m2,dl-d3) per week, one cycle per 4 weeks was given. Radiation was given after 2-3 cycles. CCRT group (32 patients) received radiotherapy plus concurrent chemotherapy with DDP(20 mg/m2,dl-d5) and VP-16 (50 mg/m2,dl-d5) per week for 8 weeks. In either group, radiation was given with a total dose of 60-70 Gy/6-7 weeks. Results One patient was excluded from ICRT group for development of distant metastasis, and 3 from CCRT group for their acute complications or other diseases. The overall response rates ( CR + PR) of ICRT and CCRT groups were 81.3% and 84.4%, respectively . NR + PD rates of both groups were 18.7% and 15.6% . The median survival periods were 13.4 months in ICRT group and 21.6 months in CCRT group (t = 2.58, P
