Objective To assess the incidence, types and risk factors of atherothrombotic events (AT) within 7 days after transient ischemic attack (TIA) with ABCD2 Score in Chinese patients. Methods With ABCD2 Score, we retrospectively reviewed the medical records of 198 TIA patients ,which met the inclusion criteria of our study. They were divided into a low risk group (ABCD2 ≤3) and a moderate-high risk group(ABCD2≥4) and the incidence, types and risk factors of AT within 7 days after TIA were evaluated and compared respectively with χ2 test between the two groups. Statistic significance was considered as P < 0.05. Results The order of the frequency of accompanying diseases was hypertension 68.18% (135/198), diabetes 23.74% (47/198), coronary artery disease 21.72% (43/198), ischemic stroke 15.66% (31/198) and hyperlipemia 12. 63% (25/198). AT within 7 days after TIA was observed in 6.19% (6/97) of the patients in the low risk group, all of them were suffering from TIA recurrence. In the moderate-high risk group, 14. 85% (15/101) of the patients experienced AT, including 2 eases of TIA recurrence, 10 cases of ischemic stroke, 1 case of both TIA recurrence and ischemic stroke, 1 case of angina pectoris and 1 case of myocardial infarction. There was no peripheral vascular disease or death from vascular disease. Incidence of AT within 7 days in the moderate-high risk group was significantly higher than that in the low risk group (51.70% vs 27. 27%, P < 0.05). Conclusion TIA patients with ABCD2 ≥4 are at higher risk of AT within 7 days after TIA onset.

Objective To evaluate the clinical effects of intra-lamellar orbicularis dissecting micro-traumatic double eyelid surgery for the treatment of adolescent upper eyelid trichiasis. Methods Three cutaneous micro-incisions following intra- and sub-lamellar orbicularis dissections were performed and the deep orbieularis and suborbicularis fat pad between the intended eyelid crease and 1 mm above the eyelid margin were resected. The subcutaneous orbicularis was fixed to the exposed levator aponeurosis at the medial, center and lateral regions. For the quantitative analysis, the entire eyelid margins' eyelashes were equally divided into three sections and the eyelashes lift-up angle (LA), the body curl-up angle (BC) and the end curl-up angle (EC) were compared before and after surgery in each section, respectively. Results One hundred and fourteen eyes of 57 cases were followed up during 24-30 months. Compared to the LA before surgery and 2 years after surgery, it was changed from (26.37±9.67)° to (55.42± 10.03)° in section Ⅰ , and from (22.03±11.64)° to (50.03±10.02)° in section Ⅱ , and from (25.31±8.01)° to (64.05±8.33)° in section Ⅲ. There were no significant changes of BC and EC during following-up. Con-clusions For the adolescent upper eyelid trichiasis, the intra-lamellar orbicularis dissecting micro-trau-matic double eyelid surgery could acquire satisfactory aesthetic appearance and stable eyelashes'position at the same time.

Objective To study the postoperative recovery in patients undergoing coronary artery bypass grafting (CABG)with a history of cerebral infarction.Methods From January 2007 to December 2007,112 patients undergoing elective off-pump coronary artery bypass grafting(OPCABG)with a history of cerebral infarction were studied retrospectively.Each of the 112 patients was matched with 1 control patient who had no cerebral infarction history and were undergoing an elective OPCABG either immediately before or immediately after the study patient,in most cases by the same surgeons.Preoperative characteristics,anesthesia time,awakening time,extubation time,ICU stay,hospital stay,reintubation,hospital mortality,postoperative confusion and stroke were compared in the two groups.Results There were no significant differences between the study and control Patients in the most preoperative characteristics,only the incidence of hypertension and diabetes mellitus were higher than those in control group,P<0.05(78 of 112,69.6% versus 61 of 112,54.5%;52 of 112,46.4% versus 26 of 112,23.2%).The study group took longer to awaken,extubate and stay in ICU and hospital than the control group,P<0.01[(6.4±4.0)h versus(4.6±2.7)h,(19.6±9.7)h versus(16.8±5.5)h,(27.3±16.8)h versus(22.1±10.6)h,(23.4±10.0)d versus(19.5±5.6)]d.The incidence of confusion,stroke and reintubation after operation among the study group was higher than those in control group,P<0.05(17 of 112,15.2% versus 4 of 112,6.3%;8 of 112,7.1% versus 1 of 112,0.9%;8 of 112,7.1% versus 1 of 112,0.9%),RR and 95% CI were 4.83(1.57～14.86)、8.54(1.05～69.45)and 8.54(1.05～69.45).There were no significant differences between the study and control patients in the anesthesia time and hospital mortality.Stroke after the operations was found in 8 of 112 study patients and included cerebral infarction in 6 and transient ischemic attack(TIA)in 2.The 8 patients included new stroke in 7 and worsening of old stroke in 1 without new abnomalities on head computed tomography.1 of 8 patients had early stroke(≤24 hours after operation)and others had late stroke(>24 hours).Conclusion The patients with previous cerebral infarction undergoing off-pump coronary artery bypass grafting took longer to awaken,extubate,stay in ICU and hospital.These patients were more likely to have reintubation,confusion and stroke after operation than those patients with no cerebral infarction history.

Objective To investigate the value of X-ray Knife in the stereotaxis radiotherapy of lung cancer.Methods 52 cases with pulmonary carcinoma were treated with X-ray knife,before and after that,general radiotherapy was applied.After whole radiotherapy,2 or 3 months later,all patients were followed by CT scan.The changes of tumor and clinical appearances were compared before and after therapy.The curative effect was estimated according to clinical appearances and CT findings.Results 6 patients were complete response(11.5%) ,29 patients were partial response(55.8%) and 13 patients were no changes or reduced less than 50%.The total responsive rate was 92.3%.Conclusion The treatment of lung cancer with X-ray Knife can give tumor accuracy high dosage irradiation.The short term therapeutic effectiveness is significant and safe on clinical.

Objective To study and evaluate the ability of allogeneic bone marrow stromal cells(BMSCs) to survive and regenerate bone in muscles without using immunosuppressive agents. Methods A complete mismatch between donor BMSCs and recipient rabbit was confirmed by one way mixed lymphocyte reaction assaysprior to implantation. And then bone marrow aspirates were obtained from donor rabbits.BMSCs were isolated from the bone marrow, cultured in conditional medium to be ubdyced to become osteogenic, and then to examine these characteristics. After that the donor BMSCs were transplanted into the recipient rabbits. Immunological tests such as lymphocyte transformation rate and cell mediated cytotoxity, histological observation, seeding cells survival and bone formation were performed following transplantation. Results Allogeneic BMSCs transplantation did not actually elicit an adverse immune response, and bone regenerated at the transplantation area, and then the transplanted BMSCs marked with BRDU preoperatively were founded to be living 8 weeks later after transplantation using immunohistochemistric technique. Conclusion Allogeneic BMSCs would not elicit an adverse immune response in vivo without the immunosuppressive therapy, which could survive and form new bone tissue with the help of BMP-2 in the muscles.

BACKGROUND:Comeal graft endothelial cell density may decline spontaneously at a super-physiological speed after penetrating keratoplasty (PKP),even if no corneal rejection happens,and this is chronic corneal allograff dysfunction (CCAD).OBJECTIVE:To investigate the effects of topical corticosteroid treatment on chronic corneal allograft dysfunction after PKP.DESIGN,TIME AND SETTING:A controlled clinical analysis was performed at the Department of Ophthalmology,Tongji Hospital,Tongji University from May 2004 to May 2009.PARTICIPANTS:A total of 54 patients (eyes) who underwent PKP were included in this study.METHODS:Tobramycin-dexamethasone eyedrops was applied 6 times per day as an initial dosage and tapered during 4 months.Thereafter,drug withdrawal group and long term group were randomly divided.Treatments were ceased in the drug withdrawal group but were continued in the long-term group with a dosage of twice per day till 12 months after surgery.MAIN OUTCOME MEASURES:Corneal graft endothelial cell density was followed up.The mean follow up pedod was 3.12±0.28years.RESULTS:The corneal graft endothelial cell density of drug withdrawal and long term groups was dramatically declined within 36 months after PKP.At every time point,the endothelial cell density was significantly decreased compared to the last follow up (all P＜0.01 ).The endothelial cell density was decreased from (2 428±2.11) cells/mm~2 and (2 791±2.29) cells/mm~2 to (1 424±124) cells/mm~2 and (1 614±114) cells/mm~2 in the drug withdrawal and long-term groups,respectively.There was significant difference in endothelial cell density between the two groups no matter prior to surgery or at each time points after surgery,but the declination trends of two groups were basically the same,indicating that graft loss of endothelial cell density was not impacted by topical corticosteroid treatment after PKP (P＞0.05).CONCLUSION:Chronic corneal allograft dysfunction after PKP is independent of topical corticosteroid treatment.

Objective To investigate the clinical characteristics of stroke in young patients with cardiac myxoma.Methods Medical records of young patients (aged between 18-44 years) diagnosed with cardiac myxoma in Beijing Anzhen Hospital affiliated to Capital Medical University from January 2005 to March 2016 were retrospective reviewed.Results A total of 117 cases were included (85 female and 32 male)with the average age (36 ±7)years old.Most myxomas (83.8％) were located in the left atrium,7.7％ were in the right atrium,3.5％ were in the both atriums,2.6％ were in the left ventricle,and a few were in the left atrium plus left ventricle and in the right ventricle.Of all the patients,24 (20.5％) (16 women and 8 men) were complicated with cerebral infarction.Among them,3 patients were with lower extremity arterial embolisms.Two patients were with cerebral hemorrhage.The cerebral infarction mainly involved in the distribution area of the internal carotid artery.Infarctions involving 2 or more cerebral vessels were found in 4 cases.Most subjects (58.3％) manifested with hemiplegia,and some (18.2％) with syncope.The proportion of the left atrial myxoma in patients with cerebral infarction (100.0％) was significantly higher than those in patients without cerebral infarction (85.1％,P =0.044).Subjects with tumor diameter less than 3 cm were more frequently complicated with cerebral infarction (37.5％ vs 13.8％,P =0.009).A logistic analysis showed that the odds ratio of myxoma with tumor diameter less than 3 cm for cerebral infarction was 3.750 (95％ CI 1.343-10.470).Conclusions Cardiac myxoma is more common in young women,and often complicated with cerebral infarction.The infarctions are mainly distributed in internal carotid artery system,and some are involved in multiple vascular systems.The incidence of stroke is associated with the position of the myxoma.Smail-size myxoma cannot be ignored for its risk of stroke.

Objective To assess attitudes and its related factors of Chinese military personnel on homosexual served in the military.Methods 1362 enlisted military personnel,selected from land force by cluster sampiing,were interviewed by Military Personnel's Attitudes Toward Homosexuals in the Military Scale(ATHM).Results The attitudes of the present sample toward homosexual served in the military were found to be negative(the total score on the ATHM scale was (29.28 ± 6.59).The threat dimension made the biggest contribution to the negative attitude,followed by the comfort dimension.Marital status was negatively related to the total scores of ATHM (r =-0.067,P ＜ 0.05),and other demographic variables such as age,only child,nationality,childhood environment,education level,years of service,and military rank were not associated with attitudes toward homosexuals in the military (r =-0.01,0.002,-0.035,-0.041,-0.015,-0.041,-0.039,P ＞ 0.05).Further multiple linear regression analysis found that marital status was one of the attitudes' predictors.Conclusion Because of the threat and discomfort with homosexual,the attitudes toward homosexual in the military are mildly negative,and marital status correlate with it.

Real world clinical diagnosis and treatment activity is a complicated decision-making task. The effective clinical cases of traditional Chinese medicine (TCM) of highly experienced physicians play an important role in the routine diagnosis and treatment and the formulation of medical knowledge . Based on TCM electronic medical record data, this paper proposed a decision support prototype system on TCM clinical diagnosis and treatment based on TCM effective clinical cases and case-based reasoning (CBR) algorithm, which is used to assist inexperienced clinicians to make more reliable clinical decisions, and thereafter to improve the clinical curative effectiveness. The system integrates TCM clinical cases data set from a TCM clinical data warehouse, and retrieves the similar cases based on CBR method. In particular, according to the underlying personalized diagnosis and treatment for patients in TCM, this system implemented a flexible diagnosis and treatment modification mechanism based on correlation analysis among symptoms, diagnoses (syndrome or pattern in TCM) and medicine. Finally, through a demonstration of clinical application, we made an initial evaluation of the usefulness and practical effects of the system.

Objective To study the expression of thymic stromal lymphopoietin(TSLP) and the activation of DCs in OVA-induced murine asthma model, and investigate the effects and underlying mecha-nisms of TSLP on lung inflammation. Methods Thirty BALB/c mice were randomly divided into control group, OVA group and TSLP neutralizing antibody treated group. The asthma model was evaluated by airway responsiveness and histological analysis of lung tissues ; The levels of TSLP mRNA in lungs were determined by quantitative real-time PCR; The expression of TSLP in lungs were determined by immunohistochemistry and Western blot; The expression of CD40, CD80, CD86 in BALF was detected by FACS. Results Both the histological analysis of lung tissues and the airway responsiveness were all consistent with the characteris-tic of murine asthma model. The expression of TSLP and TSLP mRNA in the OVA group was significantly in-creased compared with blank group. The expression of CD40, CD80, CD86 in BALF from OVA group was increased significantly compared with the control group. Furthermore, treating mice with TSLP neutralizing antibody reduced the expression of CD40, CD80, CD86 on dendritic cells, and IL-4, IL-5, IL-13 in the OVA group. Conclusion Our study indicate that TSLP was highly expressed in the bronchial epithelia of murine asthma model, via upregulation of CD40, CD80, CD86, induce DCs to active CD4~+ T cells and pro-duce type 2 responses, so that aggravating the lung inflammation of asthma. Blocking TSLP is capable of in-hibiting the production of Th2 cytokines, thus presents a promising strategy for the treatment of asthma.
