With the application of drug eluting stent implantation in coronary intervention, the safety and effectiveness of surgical treatment of obstructive coronary artery disease have has been improved, while the postoperative complications still appear to be a concern. In recent years, studies have found that in-stent neoatherosclosis may be an important factor in the development of late stent failure. And with the development of imaging techniques, the in-stent neoatherosclosis after drug eluting stent implantation has been further recognized. However, the mechanism of the development of in-stent neoatherosclosis is still not very clear.

Objective:To explore the correlation between the characteristics of contrast-enhanced sonography of intraoperative glioblastoma multiform (GBM) and molecular markers of isocitrate dehydrogenase-1(IDH1).Methods:A retrospective analysis were performed in 30 patients who underwent neurosurgery and pathologically confirmed to be GBM at Beijing Tiantan Hospital from May 2018 to April 2019. All neurosurgical glioblastoma patients after craniotomy underwent conventional ultrasound and contrast-enhanced ultrasound(CEUS) guided navigation. The characteristics of the ultrasound imaging (whether the tumor involves the structure of the corpus callosum, the clarity of the tumor boundary after enhanced ultrasound and whether the tumor has necrotic areas with enhanced ultrasound images) were analyzed. The ratio between tumor necrosis area and whole tumor area (N/W) was measured, and the correlation with IDH1 gene expression was analyzed.Results:There were statistical differences in clarity of tumor boundary after CEUS and tumor necrosis after CEUS between positive IDH1 and negative IDH1 groups(all P<0.05). The positive expression of IDH1 was negatively correlated with the N/W area of the contrast-enhanced ultrasound mode( r=-0.756, P<0.05), suggesting that the expression level of IDH1 gene was negatively correlated with the area of tumor necrosis. Conclusions:Ultrasound contrast agent examination can more accurately distinguish the active proliferation area, hemorrhagic necrosis area and peripheral edema area of glioblastoma. Accurately identifying the extent of tumor necrosis area through ultrasound contrast agent examination can predict expression of IDH1.

Objective To study the methods and skill of vena cava filter placement via the antecubital access. Methods Six patients with DVT (4 males and 2 females, mean age of 62) underwent vena cava filter placement via the antecubital access in Huashan Hospital from Oct. 2004 to May. 2006. The right basilic vein was punctured with the use of micropuncture technique. SNF (Simon nitinol filter, Bard)was inserted through its carrier into the 90-cm-long sheath. The filter was then deployed with a standard fashion in the IVC, 5 cm inferior to the renal vein. Results The filter was once placed successfully in all six patients within average time of 25 min without complications, but with good healing, exclusion of bleeding and no phlebitis. The position of filter was accurate without deviation and no occurrence of pulmonary embolism. Conclusions vena cava filter placement via antecubital access is easy, minimal invasive, no need of lying in bed postoperatively. It is beneficial for DVT patients as an alternative for the contra-indication to femoral venous access.

Objective To evaluate the effect of health education on endemic diseases in Henan province in 2010.Methods According to the requirements of The Education Program for Endemic Diseases Control in 2009 Henan Province,50 counties (districts) of 18 cities with endemic diseases were selected.Referring to the health education questionnaire in the program,knowledge of endemic diseases were asked of pupils and housewives.Intervention effects were evaluated two months after teaching pupils and housewives in counties,towns,villages and schools with the knowledge of endemic diseases and the questionnaire was used.Results Among 50 counties investigated,5523 pupils and 3206 housewives were surveyed in the baseline according to the requirement,and 5417 pupils and 2891 housewives were surveyed for outcome evaluation.The results showed that after this education,pupils' knowledge about endemic diseases increased from 66.31％(10 987/16 569) in the baseline survey to 93.84％(15 250/16 251),the difference have statistical significant(x2 =3877.78,P ＜ 0.01) ; housewives from 67.56％(6133/9078)to 92.67％(8037/8673),the difference have statistical significant(x2 =1736.33,P ＜ 0.01).After the education,the pupils' knowledge about the iodine deficiency disorders,drinking-water-borne fluorosis and arsenic poisning,coal-burning-borne fluorosis increased from 70.15％ (6263/8928),62.29％(4423/7101),42.96％ (185/270),68.52％ (116/270) to 94.19％ (8344/8859),93.05％ (6376/6852),99.63％ (261/270),96.67％ (269/270),the difference have statistical significant (x2 =1749.85,1939.26,211.83,74.43,all P ＜ 0.01),housewives' knowledge about the iodine shortage diseases,drinking-water-borne fluorosis,the endemic fluorine,the arsenic poisoning increased from 73.27％ (3330/4545),62.79％ (2677/4263,30.37％ (85/135),62.96％(41/135) to 93.96％(4228/4500),91.08％(3555/3903),97.04％(123/135),91.11％(131/135),the difference have statistical significant (x2 =751.03,924.65,129.75,30.23,all P ＜ 0.01).Conclusions Health education intervention has a marked effect in increasing the peoples' knowledge of endemic diseases.Therefore health education should be enhanced in the future.

Purpose To investigate the clinicopathological and immunohistochemical features of primary small cell carcinoma of the cervix ( SCCC) and its prognosis. Methods 18 cases of primary cervical small cell carcinoma were evaluated by histopathology, in si-tu hybridization and immunohistochemistry and relevant literatures were reviewed. Results The age of the patients ranged from 30 to 69 years ( mean age, 40 years) . Major clinical manifestation was irregular colporrhagia. Colposcopy often revealed a cervical mass or cervical erosion. Microscopically, the tumor cells were small and round and arranged in a solid distribution. The cell had little cyto-plasm and increased karyoplasmic ratio with deeply stained granular chromatin and increased pathological mitosis. Immunohistochemi-cally, the tumor cells were often positive for CKpan, variable positive for Syn, NES, CgA, CD56 and p16. HPV 16/18 were positive in 4 cases. Conclusion SCCC is a neuroendocrine tumor of high malignancy and poor prognosis with a possible pathogenesis of HPV 16/18 infection. CKpan, Syn, CgA, NSE and CD56 are useful markers for the diagnosis of SCCC.

Objective To explore the safety and clinical effect of the human acellular nerve allograft (hANG) for repairing peripheral nerve defects.Methods During November,2009 to October,2010,6 patients with 3 digital nerve defects and 3 radial nerve defects were repaired with hANG.During postoperation period,safety was evaluated by local wound response and laboratory testing,while the efficacy was evaluated by British Medical Research Council sensory function assessment standards,static 2-point discrimination (2PD) and Semmes-Weinstein monofilament testing.Results Three patients with 6 digital nerve defects received hANG transplant.The length of nerve graft was 20-50 mm(mean 30.8 mm).After followed up for 31-40 months,the excellent rate of 2PD was 66.7％.Two of 3 patients rahabilited as well as the normal.Three patients with radial nerve defects,whose length of nerve graft was 35-60 mm(mean 48.3 mm).The strength of extensor carpiradialis longus muscle had restored Ⅲ in 1 case,and other 2 cases had no restoration.Conclusion hANG is safe and effective for repairing peripheral nerve defects,especially for digital nerve defects.

Purpose To study the clinicopathologic features retrospectively and to explore the prognosis of 15 cases of young pulmonary primary salivary gland tumor. Methods The 15 cases of young pulmonary primary salivary carcinoma were analyzed respectively. Re-sults The 15 cases showed 7 cases with adenoid cystic carcinoma and 8 cases with mucoepidermoid carcinoma. Cough and bloody sputum were main symptoms, while chest pain, chest distress and fever were less seen. There were 10 cases performed with partial pul-monary lobectomy, 3 cases performed with unilateral total lobectomy, 1 case performed with artery perfusion treatment and bronchial ar-tery embolization and 1 case performed with conservative treatment for pancreatic metastasis after diagnosis. The mean follow-up time was 28 months ( from 4 to 96 months) . Conclusion The primary salivary gland-type lung tumor belonged to benign or low-grade ma-lignant tumor, mainly accompanied with hacking cough and bloody sputum, which was commonly found in trachea and bronchus. Final diagnosis could be made through bronchoscopy and biopsy. Complete surgical excision is the primary method and the prognosis is usual-ly good, especially in the young.
