Objective To analyze the immunization coverage of 23-valent pneumococcal polysac-charide vaccine(PPV23)in a large population in Guangzhou and to evaluate its safety by analyzing the ad-verse events following immunization(AEFI)reported to the passive surveillance system. Methods Immu-nization data of PPV23 in Guangzhou from 2010 to 2015 were collected from Information Management System of Biological Products and the Information System of Immune Programming of Guangzhou. AEFI reported to the AEFI Information System during 2010 to 2015 was collected for safety evaluation. The collected data were analyzed by using descriptive methodology. Results A total of 621 059 doses of PPV23 were pre-scribed in Guangzhou from 2010 to 2015. Most of the recipients were children younger than 10 years old,ac-counting for 79. 44% . Only 9. 38% of the subjects received PPV23 were older than 60 years. A total of 243 AEFI cases were reported at a rate of 39. 13 cases per 100 000 doses,among which 199 cases(32. 04 / 105 ) showed minor vaccine reactions,25 cases(4. 03 / 105 )occurred adverse events,16 cases(2. 58 / 105 )de-veloped coupled diseases and 3 cases(0. 48 / 105 )were classified as psychogenic reactions. No rare adverse reactions were observed. Conclusion The majority of people immunized with PPV23s in Guangzhou were children,while the immunization coverage among the elderly was relatively low. PPV23 was safe for vaccina-tion as the reported AEFI cases were similar to that of other vaccines.

Aim To investigate the curative effect of Danshen injection combining with HSV-tk/GCV system on rats′ hepatocarcinoma cells and murine transplanted hepatocarcinoma.Methods ① Rats′ hepatocarcinoma cell line CBRH7919(tk~-),CBRH7919/tk(tk~+) and the 5% tk~+ mixed cells were treated with diverse concentrations of Danshen injection,GCV separately,and Danshen injection plus GCV(n=3).The survival rate of each groups was examined using MTT Assay and was analyzed using paired comparison.Q-value analysis method was used to estimate the synergistic effect of Chinese herbal on the suicide gene system.Q-value is a ratio of the actural effect of combination treatment to its theoretical effect.It is thought to be an additive effect when 0.85≤Q

Objective To introduce a new modified Bristow operation with mini-open incision and evaluate jts clinical outcomes in treatment of recurrent anteroinferior shoulder dislocation. Methods A total of 11 patients with recurrent anteroinferior shoulder dislocation were treated with modified Bristow op-eration with mini-open incision.The anterior skin incision with 3-5 mm was made to explore the coracoid process with"moving window"technique.Then.the coracoid process and its short head of biceps were os-teotornjed.transferred and fixed on the anteroinferior potion of scapular neck through the rotator cuff inter-space.All patients were followed up for an average period of 15.8 months(6-48 months)by using modified Rowe score. Results The average operation time was 45 minutes(40-65 minutes).The modified Rowe 8core ranged from 80 to 95 points.excellent in all patients, with SUCCESS rate of 100% and without any re-currence or complication. Conclusions Compared with traditional operation.the modified Bristow oper-ation has smaller incision,less trauma.shorter operation duration and better clinical results.

Objective To evaluate it' s prognosis according to the follow-up statistics of coronary reimplantation of anomalous left coronary artery originating from the pulmonary artery (ALCAPA).Methods Analyze the preoperative,peri-operative and postoperative data of 20 ALCAPA patients having undergone coronary artery reimplantation.Results After coronary reimplantation,patient' s cardiothoracic ratio was obviously decreased,the degree of myocardial ischemia was improved according to electrocardiogram,the left ventricular ejection fraction and fractional shortening showed a trend of rise,mostof the patients recover in 6 months to 1 year after coronary artery reimplantation.Left ventricular end-diastolic volume index over time gradually returned to normal,mitral regurgitation gradually.improved.Conclusion ALCAPA is rare and fatal,therefore it should be diagnosed and treated as early as possible.It is also significant to avoid missed diagnosis and misdiagnosis.After coronary reimplantation,cardiac function can be gradually restored with low mortality and good prognosis result.The left ventricularejection fraction of most patients recovers to the normal standard in six months to one year' s time.
