Objective:To observe the clinical effect of mind-refreshing and orifice-opening needling method plus swallowing disorder therapeutic apparatus for deglutition disorder of stroke patients in convalescence stage.Methods:A total of 136 patients conforming to the inclusion criteria were randomized into three groups by the random number table,including group A of 46 cases,group B of 44 cases and group C of 46 cases.Patients in group A received swallowing disorder therapeutic apparatus treatment,patients in group B received mind-refreshing and orifice-opening needling method treatment,and patients in group C received mind-refreshing and orifice-opening needling method plus swallowing disorder therapeutic apparatus treatment.The treatment was given once a day for 10 d as a course,the whole treatment lasted for 4 courses.Therapeutic evaluation items including water-swallowing test (WST),standardized swallowing assessment (SSA) and modified Barthel index (MBI) were measured before treatment,after treatment and at follow-up visit (2 months after treatment).Results:After treatment,scores of WST and MBI in all three groups increased significantly (all P＜0.05),while the SSA score dropped significantly (all P＜0.05).After treatment and during follow-up visit period,score of WST in group C was significantly higher than that in group A and group B (both P＜0.05),while the difference between group A and group B showed no statistical significance (P＞0.05);the SSA score in group C was substantially lower than that in group A and group B (all P＜0.05),the difference between group A and group B showed no statistical significance (P＞0.05);the MBI scores in group B and group C were substantially higher than that in group A (all P＜0.05),the difference between group B and group C showed no statistical significance (P＞0.05).After treatment and during follow-up visit period,the differences in overall therapeutic effect between group A and group B showed no statistical significance (P＞0.05),while the overall therapeutic effect in group C was substantially better than that in group A and group B (all P＜0.05).Conclusion:Both mind-refreshing and orifice-opening needling method and swallowing disorder therapeutic apparatus can alleviate symptoms of deglutition disorder of stroke patients respectively,and the combination of two methods can improve the therapeutic effect.

Objective:To evaluate the antimicrobial effectiveness of Zhenzhu Mingmu eye drops according to the requirements de-scribed in Chinese pharmacopoeia (2010 edition). Methods:Totally 7 batches of Zhenzhu Mingmu eye drops from 7 enterprises were evaluated. All the samples were tested according to the requirements described in Chinese pharmacopoeia, and the testing points of 6h and 24h were added. Results:As for bacteria, the reduction value of staphylococcus aureus in 7 days treated with Zhenzhu Mingmu eye drops from enterprise e was 0. 61g, and that in 14 days was 1. 01g. That in 7 days treated with the eye drops from the other enter-prises was all above 1. 01g, that in 14 days was above 3. 01g, and that in 14-28 days kept stable. As for fungi, the number was stable from the beginning with the treatment of the eye drops from the seven enterprises. Conclusion:Although the type and content of bacte-riostatic agent in domastic Zhenzhu Mingmu eye drops are the same, there is difference in the antimicrobial effectiveness of the product from different enterprise. The eye drops from one enterprise can't meet the requirements for type I product described in Chinese pharma-copoeia,and the others meet the requirements.

Objective To study the relationships among resilience, self-awareness, personality, stress level and mental health in the warship soldiers. Methods Resilience Scale for Adults ( RSA), Eysenck Personality Questionnaire ( EPQ), Self Acceptance Questionnaire( SAQ), General Self-Efficacy Scale( GSES), Wallance Self Concept Scale (WSCS), Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90)were used to survey 1451 warship soldiers. Results ① 2.5％ of the warship soldiers reported obvious psychological stress. Mental health of warship soldiers was worse than the norm of China population, except for obsessivecompulsive and interpersonal sensitivity factor. While the scores of other factors were significantly higher than the norm of Chinese soldiers(P＜0.01). ②The total scores of SCL-90, psychological stress and resilience, internal/external had negative correlation with self-awareness, and positive correlation with neuroticism. Compared to the SCL-90-negative group,SCL-90-positive soldiers (SCL-90 total score ＞ 160) had higher scores of nervousness and PSET and lower scores of RSA, internal/external and self-awareness (P ＜ 0.01 ). ③Regression analysis showed that stress levels, emotional stability,self-awareness and resilience were able to predict 35.1％ of mental health in warship soldiers. Mental health, emotional stability, internal/external and resilience were able to predict 33.2％of individual's stress level. Conclusion To some extent, warship soldiers have psychological stress and mental health problems. Resilience, personality, self-awareness are important factors affecting psychological stress and mental health.

Objective: To explore the peri-operative treatment and 3 years post-operative outcome in patients with rheumatic mitral valve stenosis and small left ventricle. Methods: A total of 152 patients with rheumatic mitral valve stenosis and severe pulmonary hypertension were studied. According to left ventricular end diastolic index (LVEDI) value, the patients were divided into 2 groups: Small left ventricle (Small) group, the patients with LVEDI value≤60 mm, n=67 and Non-small left ventricle (Non-small) group, the patients with LVEDI value>60 mm,n=85. Peri-operative condition and follow-up parameters were compared between 2 groups. Results: Compared with Non-small group, Small group had increased pre-operative CVP, SPAP and decreased LVEDV, LVEDVI and RVEF at admission, all P<0.05. All patients had liver damage at admission, the indexes (except alkaline phosphatase) were higher in Small group than Non-small group, and the function was recovered prior operation by proper treatment. The immediate post-operative SPAP in Small group and Non-small group were (67.3.1±23.4) mmHg and (61.3±26.9) mmHg, P>0.05. There were 52 severe pulmonary hypertension patients received iloprost inhalation, their SPAP was decreased than non-inhalation patients at incision closing; SPAP was lower in Small group inhalation patients than Non-small group inhalation patients, all P<0.05. Post-operative LVEDVI was lower and SPAP was higher in Small group than Non-small group. At 3 years post-operation, LVEDVI, RVEF increased, NYHA classification decreased and 6MWT prolonged in both groups; while LVEDVI was lower and 6MWT was shorter in Small group than Non-small group, P<0.05. The median survival time at (3.7±1.6) years post-operation was shorter in Small group than Non-small group,P<0.05, while the mortality was similar between 2 groups (2.6% vs 2.0%),P>0.05. Conclusion: The patients with mitral valve stenosis and small left ventricle had the worse pre-operative condition and higher risk in surgery; peri-operative treatment could improve their cardiac and liver function, but they still had the shorter post-operative median survival time.

Objective: To analyze the long-term prognosis of re-operation in patients with functional tricuspid regurgitation (FTR) after left sided valve replacement (LSVR) and hence evaluate the optimal timing of mentioned re-operation. Methods: A total of 59 FTR patients who had re-operation after their prior LSVR in our hospital from 1999-01 to 2013-01 were analyzed. The clinical information and post-operative follow-up results were recorded in all patients. Results: There were 5/59 (8.5%) patients died in peri-operative period and the overall post-operative mortality was 11.9% (7/59). The follow-up data of 54 survivors were available for the mean time of 51.1 (21-188) months. There were 19/54 (35.2%) patients suffered from MACE and 30 (55.6%) were beneifted by improved cardiac function. Uni-variable analysis indicated that pre-operative NYHA class IV (P=0.008), pre-operative right ventricular (RV) dysfunction (P=0.037), concomitant left-sided redo-operation (P=0.017) and TVR operation (P=0.002) were associated with all cause mortality of tricuspid re-operation. Multi-variable Cox regression analysis showed that pre-operative RV dysfunction was the only independent risk factor of long term MACE-free accumulating survival rate (HR=3.0, 95% CI 1.11-8.2,P=0.031); while TVR operation (HR=12.8, 95% CI 1.53-107.02,P=0.019) and pre-operative NYHA class IV (HR=5.3, 95% CI 1.20-24.51,P=0.032) were the independent risk factors for long-term mortality in patients after tricuspid re-operation. Conclusion: Patients with compensatory RV function showed better long term prognosis after secondary tricuspid operation. Aggressive re-operation before the occurrence of right ventricular dysfunction could be beneficial for relevant patients.

Objective To evaluate the efficacy and safety of oral propranolol versus atenolol in the treatment of infantile hemangioma(IH). Methods A total of 75 infants with IH aged 5-24 weeks were randomly divided into two groups: propranolol group(n = 30)orally administrating propranolol 2 mg · kg?1 · d?1 in 3 divided doses daily for 24 consecutive weeks, atenolol group(n=45)orally administrating atenolol 1 mg · kg?1 · d?1 once a day for 24 consecutive weeks. After 1?, 4?, 12?, 24?week treatment, the infants with IH were followed and adverse reactions were recorded. In addition, the activity of IH was assessed by hemangioma activity score(HAS)before and after 24?week treatment, and changes of HAS were compared between the propranolol group and atenolol group. Results There was no significant difference in the proportion of patients experiencing satisfactory regression of hemangioma between the propranolol group and atenolol group(70%[21/30]vs. 75.6%[34/45], P>0.05). Treatment failure occurred in one patient in the propranolol group because of severe airway hyperreactivity, and in another patient in the atenolol group because of drug resistance. The incidence rates of gastrointestinal reactions, central nervous system adverse effects, chills on the extremities and bronchiolitis complicated by airway hyperreactivity were all significantly higher in the propranolol group than in the atenolol group(all P<0.05). None of hypotension, hypoglycemia and bradycardia occurred in the two groups. Conclusion Compared with propranolol, atenolol shows similar efficacy but less adverse effects in the treatment of IH.
