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.

ObjectiveTo explore the clinical manifestations of infant cytomegalovirus infection in different age. MethodThe clinical data of 237 infants who suffered from cytomegalovirus infection was analyzed retrospectively and divided into three groups: 0-3 months old (77 cases,group A) ,4-6 months old ( 65 cases , group B ) , 7-12 months old ( 95 cases , group C ). ResultsThe incidence of respiratory infection was the highest among all infectious organs in three groups, the numbers of patients who had wheeze in group A was less than that in the other two groups[24.7％(19/77) vs. 61.5％ (40/65), 61.1％( 58/95 )](P ＜ 0.01 ).The incidence of jaundice decreased gradually as the babies grew up[23.4％( 18/77 )→7.7％(5/65 )→1.1％( 1/95 )](P ＜ 0.05). There was no significant difference in diarrhoea and bleeding among three groups (P＞0.05 ). The proportion of alanine aminotransferase], aspartate amino transferase increasing was similar among three groups, but gamma-glutamyl transferase (GGT) was different, the proportion of GGT increasing was 77.9％ (60/77) in group A which was higher than that in the other two groups[10.8％ ( 7/65 ), 2.1％ ( 2/95 )].Granulocytopenia in group B was obviously decreased compared with the other two groups (P ＜ 0.05 ), anemia was easily occurred in group C (P ＜ 0.05 ). ConclusionThe injury of cytomegalovirus infection may be related to month old.

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.

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.

Objective To evaluate right hepatic veins exclusion in the prevention of massive bleeding and air embolism during the resection of huge hepatic cavernous hemangioma near the second hepatic portal. Method This is a retrospective study on the clinical data of 12 hepatic hemangioma patients at the Live Surgery Department of Zhejiang Provincial People's Hospital from 2004. 1 to 2010.3. In all patients the huge hepatic cavernous hemangioma was adjoining the second hepatic portal. Block webbing or vascular clamp were used to exclude the right hepatic veins. Among the 11 patients without hepatic cirrhosis Pringle maneuvre was applied in 5 cases and selective hepatic inflow occlusion in 6 cases. Patients with hepatic cirrhosis used hemi-hepatic blood inflow occlusion. Results During the surgery no rupture of right hepatic vein happened. Nine patients used vascular block webbing and 3 patients used vascular clamp.Six patients without cirrhosis used the complete hepatic inflow occlusion and other patients without cirrhosis used hemi-hepatic blood inflow occlusion. Cirrhotic patients used hemi-hepatic blood inflow occlusion. All the operations were successful. Intraoperative blood loss ranged from 200 - 5800 ml, averaging 680 ml. Three patients needed not blood transfusion. There was no right hepatic vein rupture or air embolism. Conclusion Right hepatic veins exclusion is a useful technique to prevent massive bleeding and air embolism caused by the rupture of right hepatic vein during the resection of huge hepatic cavernous hemangioma.

Objective To evaluate the effects of selective hepatic vascular occlusion SHVO) on the prognosis of patients undergoing hepatic resection for huge liver cancer.Methods The clinical data of 49 patients who received huge liver cancer resection at the Zhejiang People's Hospital from January 2005 to January 2010 were retrospectively analyzed.Based on the type of hepatic vascular occlusion,all patients were divided into Pringle's maneuver group (24 patients) and SHVO group (25 patients).The intraoperative condition,postoperative recovery of hepatic and renal function,incidence of complications,survival rate and recurrence rate of liver cancer of the 2 groups were compared.All data were analyzed by using the t test or Fisher exact probability.The survival curve was drawn by using the Kaplan-Meier method and the survival of the 2 groups was compared by using the Log-rank test.Results Hepatectomy was successfully performed on all the patients.Time for blood occlusion were (32 ±19) minutes in the Pringle's maneuver group and (34 ± 22)minutes in the SHVO group,with no significant difference between the 2 groups (t =2.45,P ＞ 0.05).The volume of blood loss of the Pringle's maneuver group was (736 ± 543) ml,which was significantly greater than (273 ± 298) ml of the SHVO group (t =6.87,P ＜0.05).The incidences of hepatic vein rupture were 21％ (5/24) in the Pringle's maneuver group and 24％ (6/25)in the SHVO group,with no significant difference (x2=1.45,P＞0.05).The course of 3 patients was complicated by hepatic vein rupture and hemorrhage and 1 by air embolism in the Pringle's maneuver group,while no hemorrhage or air embolism happened in the SHVO group.Four patients in the Pringle's maneuver group and 3 in the SHVO group were found with vascular invasion,while the resection margins were negative.There was no significant difference in the hepatic function in the 2 groups before operation.The levels of alanine aminotransferase in the SHVO group at postoperative day 1 and 3 were significantly lower than those in the Pringle's maneuver group (t=7.12,6.35,P ＜ 0.05).There was no significant difference in the levels of blood urea nitrogen and creatinine between the 2 groups (P ＞ 0.05).Acute hepatic dysfunction was found in 4 patients in the Pringle's maneuver group,but no patients with acute hepatic dysfunction was found in the SHVO group.The 1-and 3-year tumor-free survival rates were 58％ and 21％ in the Pringle's maneuver group,which were significantly lower than 72％ and 30％ in the SHVO group (x2 =5.32,6.07,P ＜ 0.05).The 5-year tumor-free survival rates were 21％ in the Pringle's maneuver group and 20％ in the SHVO group,with no significant difference between the 2 groups (x2 =1.78,P ＞ 0.05).Conclusion SHVO is safe,feasible and effective to prevent hemorrhage and postoperative acute hepatic dysfunction,and it is also helpful in reducing early-stage tumor recurrence and improving the tumor-free survival rate in patients with huge liver cancer.

Objective:To observe the changes of the structure and visual function of the retina in patients with or without the ectopic inner foveal layers (EIFL) and to explore the factors influencing the recovery of visual function in patients with idiopathic epimacular membrane (IMEM).Methods:A retrospective clinical study. From March 2015 to June 2019, 90 patients with MEM who were diagnosed by Ophthalmic Center of the Second Hospital of Hebei Medical University were enrolled in the study. All patients were examined by best corrected visual acuity (BCVA) and frequency domain optical coherence scan. BCVA was recorded by Snellen vision table, and it was converted into the minimum resolution angle logarithm (logMAR) vision. Among 90 eyes, IMEM grade 2-4 was 68 (75.6%, 68/90), 18 (20.0%, 18/90), 4 (4.4%, 4/90), respectively. According to this, the grade 2 was set as group A, and the grade 3 and grade 4 were combined to group B. There was no significant difference in age ( t=0.015), sex composition ratio of patients between two groups ( χ2=0.060) and the average of central macular thickness (CMT) ( F=2.277) ( P=0.904, 0.809, 0.141). The difference of average logMAR and BCVA was statistically significant ( F=35.913, P=0.000). All patients underwent 25G pars plana three channel vitrectomy with simultaneous removal of epiretinal membrane and internal limiting membrane. BCVA, CMT and improvement of IMEM grading were observed at 1, 3, 6 and 12 months after operation. BCVA, EIFL thickness and CMT were compared before and after operation by single factor repeated variance analysis; Fisher exact probability method was used to compare the changes of the anatomical structure of the eyes in the two groups at 12 months after operation. Results:1, 3, 6, 12 months after operation, the average eyes of logMAR BCVA in group A were 0.50±0.13, 0.38±0.12, 0.27±0.12, 0.19±0.10. The patients in group B were 0.66±0.14, 0.60±0.13, 0.54±0.14, 0.52±0.14. CMT in group A were 364.82±81.29, 281.65±72.45, 228.55±55.34, 182.84±56.13 μm. The patients in group B were 455.88±69.60, 440.18±68.65, 383.76±65.38, 371.39±66.60 μm. The difference was statistically significant in the two groups (BCVA: F=37.913, 11.479, 24.250, 39.013; P=0.000, 0.002, 0.000, 0.000. CMT: F=10.987, 39.610, 55.789, 79.987; P=0.002, 0.000, 0.000, 0.000). In group A, IMEM was improved to 57 eyes of grade 1 on 12 months after operation. Among the 18 eyes in group B, IMEM was improved to 1 and 3 eyes in level 1 and level 2, respectively, and no improvement was found in 4 eyes in grade 4. The difference was statistically significant ( P=0.000) in the improvement of the number of eyes in the two groups. Conclusions:The patients with IMEM without EIFL have better visual prognosis and reversible anatomical changes. EIFL is an important factor affecting the visual function and anatomical structure recovery after operation.
