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 observe the anatomical and histological features of anterolateral ligament (ALL)in the knee of Chinese adults,so as to identify the existence of ALL and provide an anatomical foundation for clinical reconstruction.Methods Ten adult knee specimens were randomly selected to be dissected,and the femoral,tibial and meniscus attachment points of the ALL were observed.The length,width and thickness were measured using the vernier caliper after the dissection.Three specimens were subjected to histological staining in the end.Results (1)ALL originated from the lateral femoral condyle—the same point of the lateral collateral ligament femoral side or the distal-anterior side,with its body divided into two branches,located in the tibia and the lateral meniscus respectively.The starting point of tibial side ALL was located at the mid-point of Gerdy's tubercle to fibula head,below tibial cartilage edge,with the meniscus point located in the lateral meniscus anterior horn and body junction area.(2) The average length of ALL is 38.89 ± 4.67 mm.The width in the femur,tibial attachment point was fan-shaped spread connected with sclerotin,being the narrowest at the joint line.The width at the femur,tibial attachment point and the joint line was 8.49 ± 1.36 mm,8.15 ± 1.38 mm and 6.49 ± 1.09 mm respectively,with the thickness of 1.33 ± 0.38 mm.The distance from tibia attachment points to the Gerdy's tubercle,fibular head and tibia cartilage margin was 22.59 ± 3.04 mm,21.15 ± 2.78 mm and 5.76 ± 0.57 mm respectively.(3) HE staining showed that ALL was dense connective tissue consisting of parallel arranged collagen fibers,while S-100 staining indicated that ALL contained sensory motor nerve fibers.Conclusion ALL is independent of the joint capsule and originates from the femoral lateral condyle.Its body is divided into two branches,located in the tibia and the lateral meniscus respectively.

Objective: To observe the morphological changes of enteric deep muscular plexuses interstitial cells of Cajal (ICC-DMP) in rats with multiple organ dysfunction syndrome (MODS). Methods: Forty Wistar rats were randomly divided into control group and MODS model group. The enteric ICC-DMP network was observed using c-kit immunohistochemical staining with whole-mount preparation technique and confocal laser scanning microscopy , and the ultraslructural features of ICC-DMP was evaluated using transmission electron microscope. Results: Compared with those in control group, the distributions and densities of intestine ICC-DMP in MODS group were significantly decreased (P < 0. 05) , the ICC-DMP network was disrupted and the ultrastructural features of ICC-DMP were severely damaged. Conclusion: The ICC-DMP network was severely damaged in rats with MODS, and the mechanism of gastrointestinal dysmotility in MODS may be related to the morphological changes of ICC-DMP.

Objective To find the source of CA 125 in serum and the values of the expression of CA125 in serum, ascites and tissue in patients with epithelial ovarian cancer. Methods Detected the expression of CA125 in the primary lesions of epithelial ovarian cancer and the metastasis in abdominopelvic cavity (peritoneal and omental metastatic lesions) by S-P immunohistochemical methods. Compared the expression of CA 125 in tuberculose focus and acute inflammation focus in abdominopelvic cavity and detected CA125 in serum and ascites by ELISA. Results The levels of CA125 in serum of the patients with epithelial ovarian cancer [(523.66±158.02)kU/L],benign epithelial ovarian tumor [(138.11±26.52)kU/L] and tuberculosis of abdominopelvie cavity [(486.56±147.10)kU/L] were higher than that with the normal ovary [(17.48±3.37)kU/L], and there were significant differences (P<0.05).The levels of CA125 in serum of the patients with epithelial ovarian cancer and tuberculosis of abdominopelvic cavity were significantly higher than that with benign epithelial ovarian tumor, and there were significant differenees (P<0.01). The levels of CA125 in ascites of the patients with epithelial ovarian cancer [(996.85±337.87)kU/L] and tuberculosis of abdominopelvic cavity [(596.78±197.10)kU/L] were higher than that with benign epithelial ovarian tumor [(179.48±63.08)kU/L] and normal ovary [(177.70±51.72)kU/L], and there were significant differences (P<0.01).The level of CA125 in ascites of the patients with epithelial ovarian cancer was higher than that with tuberculosis of abdominopelvic cavity, and there was significant difference (P<0.01). By correlation analysis, the relationship of the level of CA 125 in serum and in ascites of the patients with epithelial ovarian cancer was positive correlation(r=0.687). Conclusion Besides the original and metastatie lesions (greater omenta and peritoneum) of epithelial ovarian cancer can express CA 125, the second Maller canal, for example the peritoneum mesothelial cell can be stimulated to express CA125 by ascites, which results in the increase of CA125 in serum.

Objective To learn growth status of 6 to 11 years old children and to analyze the factors that affect the growth and development of primary school students in Changchun City.Methods A total of 3045 students from one publich primary school in Changchun City were enrolled in this investigation in October 2011.Their height,body weight,chest circumference and vital capacity were measured,and the related factors were analyzed.The optimal scaling regression was used for data analysis.Results About 2590 questionnaires were completed,1319 of which were from boys and 1271 from girls,resulting in an effective rate of 85.1％.Vital capacity were increased with age,height,body weight and chest circumference.In the the optimal scaling regression,height,body weight,chest circumference and vital capacity showed statistically significant difference (F values were 371.437,110.463,101.254 and 121.540,respectively; all P ＜ 0.05).Age and gender were the most important factors of the growth.The height of children was correlated with one-child family,household income,milk and meat intake (F values were 10.777,6.855,3.905 and 5.163,respectively; all P ＜ 0.05).In addition,children's body weight was correlated with family income,breakfast,sweets,fried foods,fish,meat,average daily sleeping time and average daily physical exercise time (F values were 3.040,13.198,10.799,4.036,4.298,18.103,7.827 and 13.602,respectively; all P ＜ 0.05).Chest circumference was related to breakfast,fish or meat intake,average daily sleeping time and average daily physical exercise time (F values were 10.249,4.525,20.560,7.371 and 14.124,respectively; all P ＜0.05).Meat intake and average daily sleeping time were positively correlated with children's vital capacity (F values were 12.180 and 4.833,respectively; both P ＜ 0.05).Conclusions The growth and development of primary school students in Changchun city is in line with the laws of children's growth and development.Eating habits,average daily sleep time and physical exercises could be the main factors affecting children's growth.

AIM: To investigate the clinical effect for treating bullous keratopathy ( BK ) by anterior corneal stromal acupuncture combined with amniotic membrane transplantation.
METHODS: Totally 35 patients ( 35 eyes ) with bullous keratopathy were treated by corneal stromal acupuncture combined with amniotic membrane transplantation. All patients preoperative and postoperative underwent anterior segment OCT, corneal topography, corneal sensitivity and confocal microscopy. To observe postoperative ocular symptoms in patients with BK, recurrence of bulla, changes in corneal thickness, corneal sensitivity and changes in the organizational structure of the layers of the cornea.
RESULTS: Thirty-five were followed up for 6-18mo. The symptom of pain disappeared in 32 cases ( 91%) in the first day after operation and did not recur during follow-up. The symptom of pain relieved in 3 cases (9%) in the first day after operation and disappeared in 3 days. Corneal epithelium of 9 cases ( 26%) were all healed within 1wk, 21 cases (60%) were all healed within 2wk, and 5 cases (14%) were all healed within 3wk. Following up for 6-18mo, there was no recurrence of symptoms or bulla. A small amount of tiny bubbles in the surrounding area appeared in 2 cases after 3 and 4wk. All patients had no neovascularization, and had smooth corneal surface. The amnions of 30 cases (86%) were thinning after 2mo, partially dissolved and absorped, not seen with the naked eye after 3mo. Thirty-four cases (97%) had no changes in vision, one case (3%) was from the light to front of the manual. After 2mo, corneal sensation decreased in 30 cases ( 86%) , corneal thickness increased from preoperative 788±35μm to 940±43μm. After 12mo, corneal thickness increased to 1060±27μm. Results of confocal microscopy: after 3mo, the number density of the trigeminal nerve fibers under corneal basement membrane reduced, shallow stromal cells became into fibrotic stroma, deep stroma was more loose, and cells swelled significantly. The number of endothelial cells reduced and form swelled more obviously compared with preoperatively.
CONCLUSION: Corneal acupuncture combined with amniotic membrane transplantation can effectively control the symptoms of BK, prevent the recurrence of BK, and especially it is a simple, safe and practical way for patients with poor visual function.

We aimed to study the effect of allitridum (All) on the transient outward potassium current (Ito) of ventricular myocytes of spontaneously hypertensive rats (SHR). Totally 30 male SHRs were randomly divided into three groups: low-dose All group (7.5 mg·kg(-1)), high-dose All group (15.0 mg·kg(-1)) and normal saline group. The other 10 sex and age matched Wistar-kyoto rats (WKY) were also taken as control group (WKY group). All animals received i.p. administration for 8 weeks. The dual enzymatic method was used to separate single ventricular myocyte from animals. Patch-clamp technique was used to record Ito and analyze the effect of All on the current. It was shown that the left ventricular hypertrophy of SHR was reversed significantly by All. Furthermore, the density of Ito was recovered in both high and low dose All groups. The peak current densities of Ito were enhanced from 18.23±3.64 to 25.17±2.86 pA/pF (P<0.01) and 36.47±5.42 pA/pF (P<0.01) at +50 mV by All 7.5 mg·kg(-1) and 15.0 mg·kg(-1), respectively, which was not significantly different with WKY group. The effect was associated with positive shift of the steady-state, close-state inactivation, and shortened recovery from inactivation of Ito. It is concluded that All decreases the remodeling of Ito of ventricular hypertrophic myocytes of SHR.

Objective To investigate the factors associated with delay in decision to seek treatment in patients with acute myocardial infarction(AMI) in Beijing. Methods This prospective,cross-sectional,multicenter survey was conducted from November 1,2005 and December 31 ,2006. The participants consisted of 799 patients with STEMI admitted within 24 h of symptom onset to 19 hospitals in Beijing. Data were collected by semi-structured interviews and medical records review. The patients were categorized into an early decision group and the a late decision group based on the 30 min cut-off. Results The median(25%,75%) decision delay in STEMI patients was 60(20, 180)min. Factors associated with late decision in an univariate analysis were age ≥65 years, retirement or unemployment, history of myocardial infarction,symptom onset at home and intermittent symptoms, whereas presence of bystanders such as friends,coworkers or even strangers,unbearable symptoms,dyspnea,sweating,syncope and attribution of symptoms to cardiac origin were related to early decision. Multivariate logistic analysis showed that history of myocardial infarction,absence of syncope, intermittent symptoms,bearable symptoms and attribution of symptoms to noncardiac origin were independent predictors of decision delay＞30 min. Patients in the early decision group had more chances to receive acute reperfusion therapies(P=0.001) and shorter time intervals from symptom onset to reperfusion therapies(P＜0.001). Conclusions To a great extent patients with AMI in Beijing delayed in decision to seek treatment. History of myocardial infarction, symptom characteristics and symptom attribution were associated with decision delay.
