OBJECTIVE:
Probe into the causes of postoperative delayed hemorrhage of low temperature plasma tonsillectomy in children.
METHOD:
The methods of retrospective analysis the difference of postoperative bleeding time and bleeding rate between tonsillectomy by the low temperature plasma and the traditional cold surgical devices in 2-14 years old children. Plasma group contained the tonsillectomy by low temperature plasma between the March in 2012 to the August in 2013. Traditional group contained the tonsillectomy by traditional cold surgical devices between the March in 2005 to the August in 2006.
RESULT:
In the 1,000 cases of plasma group, 19 cases occurred postoperative hemorrhage, the hemorrhage rate was 1. 9%. Four cases occurred postoperative primary hemorrhage in 8 hours after operation, the postoperative primary hemorrhage rate was 0. 4%. Fifteen cases occurred postoperative delayed hemorrhage, the delayed hemorrhage rate was 1. 50%, the bleeding time was 2-13 days after operation, the average number was 7. 5 days. Nine cases had wound infection and 6 cases had eaten some food improperly in these 15 cases. And in these eaten improperly cases, 4 children had eaten fruit and hard food, 2 children had eaten a little food who lost their weight. In 860 cases of the traditional group, 29 cases occurred postoperative hemorrhage, the hemorrhage rate was 3. 37%. 26 cases occurred postoperative primary hemorrhage in 8 hours after operation, the postoperative primary hemorrhage rate was 3. 02%. Three cases occurred postoperative delayed hemorrhage, the delayed hemorrhage rate was 0. 35%, the bleeding time was 2-6 days, the average number was 4 days.
CONCLUSION
It is preferable for chileren to having low temperature plasma tonsillectomy. The causes of postoperative delayed hemorrhage of low temperature plasma tonsillectomy in children are probably related to the postoperative infection, the differences of operation skills, the method of stop bleeding, eating the wrong foods, irritating cough, improper nursing and so on.

Objective To investigate the surgical selection of retinal detachment with myopic macular holes. Methods Management strategies were adopted according to the ocular symptoms of patients with high myopia involved in posterior chorioretinal atrophy, the colour showed by the bottom of macular holes and the shape of posterior staphyloma. Seventy-five eyes of 72 patients fulfilled the study criteria. The patients were followed up in an average of eight-month-observation and were divided into three groups: single 16% C2F6 gas tamponade (26 eyes of 26 patients) as group A,vitrectomy combined with 16% C2F6 gas tamponade (26 eyes of 23 patients) as group B and vitrectomy with silicon oil tamponade (23 eyes of 23 patients) as group C. Results 69.2%(18/26) of the macular holes were closed in group A, 73.1%(19/26)in group B and 87.0% (20/23) in group C after the primary surgery. Comparison of postoperative outcomes,macular hole closure rate was not significantly different among three groups (P= 0.3184). Conclusions It suggests that good anatomic retinal reattachment be achieved using any approach. However, the optimal surgical choice regarding of the personality case offered less surgical burden and more rapid visual rehabilitation to patients.

Mutagenesis of several male contraceptives in sperm bead anomalies was investigated. Results show that glycosides of tripterygium wilfordii hook (GTW) and its monomer T13, microwave induce sperm head anomalies. However, gossypol and monomer T4 and GTW do not induce sperm head anomalies. Adult male mice and rats were given orally GTW, monomer T4, T13 and gossypol. These chemical agents were delivered in 1% methylcellulose. Result indicated that frequency of abnormal sperm heads in GTW, T13 groups were significantly increased, while frequency of abnormal sperm heads in T4 and gossypol-treated animals were similar to that of normal controls. When male mice were exposed to microwaves of 0.5 kW for 1-2 min, for five weeks abnormal shape of spermatozoa could be found.

BACKGROUND: Insulin-like growth factor-1 (IGF-1) is a peptide hormone, it has been proved a promotion role on the proliferation of precursor cells. OBJECTIVE: To explore the intravenous injection of IGF-1 on the proliferation, migration and differentiation of neural stem cells in rats after cerebral ischemia. METHODS: Eight adult male SD rats were randomly divided into control group and experimental group, with 40 rats in each group. The rats in two groups were used to prepare models of focal cerebral ischemia using modified suture method, the rats in the experimental group were treated with tail vein injection of IGF-1, according to 100 μg/kg computation, the injection was given for 6 continuous days; in the control group, rats were given equal volume of saline. The rats were decapitated at 7, 14, 21, 28 days following intervention, respectively, and rats in each group were given intraperitoneal injection of the BrdU at 1 day before death. Immunohistochemistry and double staining were applied to detect the expressions of BrdU-positive cells, PSA-NCAM-positive cells, BrdU + PSA-NCAM double-positive cells, and BrdU + MAP2 double-positive cells. RESULTS AND CONCLUSION: The number of BrdU-positive cells and PSA-NCAM positive cells reached the peak at 7 days after ischemia; BrdU + PSA-NCAM double-labeled-positive cells could be detected in ischemic bilateral subependymal zone and dentate gyrus, the number was the most at 7 days, then followed by a gradual decrease; the BrdU + MAP2 double-positive cells began to increase from 14 days, and then gradually increased along with the decrease of BrdU + PSA-NCAM double-positive expression, showing a reverse trend. Intravenous injection of IGF-1 can induce the proliferation, differentiation and migration of neural stem cells in rats following ischemic brain injury.
