Objective To summarize clinical characteristics, diagnosis and surgery of abnormally origination of left coronary artery from the pulmonary artery. Methods Clinical data of 10 patients with left coronary artery abnormally originating from pulmonary artery were analyzed, including 5 men and 5 women, aged from 13 to 40 years. Definite diagnosis was made by ultrasonic cardiogram (UCG) and cardiac catheter examination. Three cases were simply abnormal origination, six cases combined with MI, and one case combined with both MI and ventricular aneurysm of left ventricular apex. Ligation of the abnormal coronary artery was done in four patients, three were given pulmonary artery inner tunnel plasty under extrocorporeal circulation. Open implantation of left coronary artery to ascending aorta were done in 3 patients, while plasty of mitral valve were performed in 5 and ventricular aneurysm resection in 1. Results One patient died postoperatively. The follow-up ranged from 1 month to 11 years. One patient received replacement of mitral valve 16 months after first surgery due to severe MI. All the followed-up patients presented no myocardial ischemia or infarction, no residual shunt or late death. Cardiac function was rehabilitated to grade 1. Conclusion Obvious blood dynamics and cardiovascular morphology changes existed in patients with left coronary artery abnormally originating from pulmonary artery. Early diagnosis and surgery should be done. Proper surgical approach is the key to success.

Objective To explore the effects of Jin's Three-needle Acupuncture combined with occupational therapy on function of upper limbs for stroke patients with hemiplegia. Methods 90 patients with stroke were randomly divided into control group (n=30), observation group (n=30) and experiment group (n=30). The control group received routine rehabilitation, the observation group received occupational therapy in addition, and the experiment group received Jin's Three-needle Acupuncture and occupational therapy in addition. They were assessed with Fugl-Meyer Assessment (FMA) of upper limbs and Barthel index (BI) before and 4 weeks after treatment. Results The scores of FMA and BI improved in all the groups after treatment (P<0.001). The difference of scores of FMA and BI before and after treatment were more in the experiment group than in the observation group (P<0.001), observation group than the control group (P<0.001). Conclusion Jin's Three-needle Acupuncture combined with occupational therapy can further improve the motor function of upper limbs and activities of daily living for stroke patients with hemiplegia.

[Objective] This study compared outcomes of in vitro maturation (IVM) and in vitro fertilization (IVF) intracytoplasmic sperm injection (ICSI) cycles after IVM of immature germinal vesicle (GV) oocytes.[Methods] ICSI was performed on metaphase II (MII) oocytes retrieved in 163 IVF-ICSI cycles (group I;n ＝ 987) or matured from GV stage oocytes in IVF-ICSI ( group II;n ＝ 132) and 37 IVM cycles ( group III;n ＝ 235).Fertilization and cleavage rates and embryo quality were compared among the three groups.[Results] The fertilization rate,cleavage rate and top quality embryos rate were higher in group I than group II and group III (84.9%,98.1%,and 61.6%;72.0%,90.5% and 22.1%l;75.3%,94.4%,and 25.1%,respectively).Blastomere numbers and morphology scores were highest in group I (P ＜ 0.05),but no significant differences existed between group II and group III.[Conclusion] The morphology of embryos developed from in vivo MII oocytes was superior to those from in vitro matured MII oocytes.No significant difference was observed in embryo morphology from immature GV oocytes in IVF and IVM cycles.

Objective To compare the diagnostic efficiency between blastomere preimplantation genetic diagnosis (PGD) and polar body PGD for chromosomal translocation carriers. Methods Group A had 8 cycles using whole painting probes for the first polar body diagnosis, while group B had 29 cycles using two subtelomeric probes and one centromeric probe for the blastomere diagnosis. Results The fertilization rate of group A was significantly lower than group B [66. 1% (72/109) vs 85.2% (304/357) , P < 0.05]. There was no significant difference in the successful biopsy rate between two groups. However, group A had a significantly higher loss rate during fixation and higher no signal rate after fluorescence in situ hybridization [ FISH, 9. 6% (12/104) vs 1.6% (4/252), 11.2% (10/89) vs 3.0% (7/233) ]. Totally, the diagnostic efficiency in group A (72. 5% ,79/109 ) was significantly lower than that in group B( 89. 8%, 230/256, P < 0. 05 ). Although both the clinical pregnancy rate( 3/7 ) and implantation rate( 22. 2% ,4/18 ) of group A were higher, the differences were not statistically significant ( P > 0.05 ). Conclusion Both methods can be used efficiently in the PGD for chromosomal translocation carriers. Blastomere PGD has a higher diagnostic rate.
