OBJECTIVETo explore treatment effect of the locking plate percutaneous external fixation to tibial fractures.
METHODSFrom July 2010 to February 2013, 8 cases with pediatric tibial fractures were treated by using unilateral locking plate percutaneous external fixation,including 6 males and 2 females with an average age of 7 years old ranging from 4 to 10. Among them, 5 cases were open fractures involving 1 case of Gustilo-Anderson type II, 3 cases of type III A, 1 case of type III B; and the other 3 cases were closed fractures involving 2 cases of AO type A3, 1 cases of type B2. The postoperative bone healing and gait impact were observed and the function was evaluated by Johner-Wruhs scores.
RESULTSAll fractures healed successfully without infection. The fracture healing time was from 3 to 6 months with an average of 3.9 months. The locking plate removal time was from 4 to 7 months with an average of 4.3 months. Among them, 7 cases were visually normal after walking with stand, 1 case of anterior tibial tendon defect affected gait. The results of Johner-Wruhs assessment were excellent in 7 cases, good in 1 case. No rub contralateral medial calf skin wounds occurenced.
CONCLUSIONThe method is simple, stable and reliable. The fixation strength is suitable for children using locking plate percutaneous external fixation. The postoperative functional recovery was excellent and the walking gait was less affected. But the point of LCP pedicle screw should be carefully selected before installation with good skin coverage.

Objective To explore the incidence,features and outcomes of in-hospital sudden cardiac death (SCD) in order to determine the predictors of survival. Methods The clinical data of 69 patients with cardiac arrest hospitalized from January 2008 through December 2010 were retrospectively analyzed.Information on genders,age,types of arrhythmia was collected and further analyzed to determine these factors associated with the occurrence and outcomes of in-hospital cardiac arrest. Results The overall incidence of SCD was 47.3 / 100 000 per year and 17.4% of them.survived at discharge.The occurrence rate was higher in male than that in female (66.7% vs.33.3%,P <0.01 ),whereas difference in gender did not affect the discharge rate ( P > 0.05 ). Survivors from in-hospital cardiac arrest were significantly younger than non-survivors (man:62.57 ± 12.83 years vs.75.56 ± 10.55 years; women:60.36 ± 13.24years vs.69.53 ± 11.72 years,P < O.01 ).From 62 ECG records of SCD patients,the incidence of nonshockable rhythms was higher than that of shockable rhythms.Compare to the non-shockable rhythms,the shockable rhythms brought a higher rate of restoration of spontaneous circulation (ROSC) (54.5% vs.24.5%,P <0.05),whereas survival rates at discharge between two groups were not statistically different ( 18.2% vs.18.4%,P > 0.05 ).Conclusions Non-shockable rhythms were more common in patients suffering from in-hospital cardiac arrest.Although defibrillation treatment contributed benefit to ROSC among patients with ventricular fibrillation or pulseless ventricular tachycardia,high-quality CPR and post-cardiac arrest care may play a more critical role in the outcomes of in-hospital sudden cardiac death.

ObjectiveTo observe effects of ginkgo bilobate extract injection on the hemorheology,blood lipid and c-reactive protein in serum of patients with cerebral infarction. Methods62 cases patients with cerebral infarction were randomly divided into two groups by means of random number table. Two groups were both given routine treatment. The control group was treated with 20ml compound salvia injection, which was added to 250 ml normal saline, once a day, continuous therapy for 14 days, and the treatment group was treated with 20ml ginkgo bilobate extract injection, which was added to 250 ml normal saline, once a day, continuous therapy for 14 days. The clinical symptoms were observed, hemorheology related index, level of blood lipid and c-reactive protein were detected before and after the treatment. ResultsCompared with the control group,hemorheology related index decreased significantly in the treatment group, especially whole blood viscosity ( 1.57±0.28) mpa ·s (P<0.01). Blood reduced viscosity (13.95 ± 2.07) mpa ·s, erythrocyte aggregation index (1.37±0.12) , hematocrit (42.36±8.16) were also decreased significantly (P<0.05) .Triglyceride (TG)(1.23±0.12) mmol/L、 cholesterol (TC) (4.29±1.17) mmtmol/L、 low density lipoprotein cholesterol (LDIL-C)(2.31± 0.39) mmol/L and c-reactive protein ( 10.48 ±- 3.82) mg/L in serum in the treatment group were lower than those of the control group (P<0.01 orP<0.05) , high density lipoprotein cholesterol (HDL-C) ( 1.78±0.76) mmol/L in serum was higher than that of the control group (P<0.01) .The total effective rate of the treatment group and the control group was 87.1% and 67.7% respectively, there was a significant difference (x2=3.553, P<0.05). Conclusion The ginkgo bilobate extract injection can protect cerebral infarction from injury,which may be related with its action on regulating the blood viscosity and level of blood lipid.

Background and purpose: Neck lymph node metastasis, most of which presents in central neck compartment, is common in patients with papillary thyroid carcinoma (PTC). The objective of this study was to investigate the relationship between the number of dissected central neck lymph nodes and clinical outcome after radioactive iodine (RAI) ablation in pN1a PTC with no more than 5 lymph nodes involvement. Methods: A total of 167 PTC patients who had 1-5 proven metastatic lymph nodes according to postoperative pathological diagnosis were retrospectively analyzed, all of whom underwent total or near total thyroidectomy and central lymph node dissection. After a median follow-up period of 26 months, the clinical outcome of each patient was evaluated as excellent response (ER), indeterminate response (IDR), bio-chemical incomplete response (BIR), or structural incomplete response (SIR) according to the new American Thyroid As-sociation guidelines. The accumulative ER rate (ERn) was calculated in patients with different numbers of dissected lymph nodes (ERn was defined as the proportion of patients who achieved ER with the dissected lymph node number of ≤n). The relationship between the number of dissected central neck lymph nodes and ERn were investigated. Results: As the increase in the number of dissected central neck lymph nodes,there was also an overall increase in ERn, especially when n rose from 1 to 10. The values of ER1, ER5, ER10 and ER30 were 25.0%, 66.7%, 74.7% and 79.1%, respectively. Besides, the proportion of patients who achieved ER was higher in those with 10 or more dissected lymph nodes than in those with less than 10 (85.7% vs 73.3%, P=0.05). In the multivariate logistic regression analysis, both the dissected central lymph node number of ≥10 (OR=2.720, 95%CI: 1.052-7.033, P=0.039) and the level of preablation stimulated thyroglobulin (OR=0.955, 95%CI: 0.926-0.984, P=0.003) were shown to contribute independently to ER. Conclusion: As the increas-ing number of dissected central neck lymph nodes, the percentage of pN1a PTC patients that achieved ER after RAI ablation generally rises. In pN1a PTC patients with no more than 5 lymph nodes involvement, a central compartment dissection with 10 or more lymph nodes might help them achieve ER after RAI ablation.
