Objective To investigate a new method in correction of epicanthus.Methods Asymmetrical Z-plasty was used in correcting epicanthus and lengthening palpebral fissure in 42 cases with 84 eyes.It could be combined with double-eyelid-blepharoplasty to create beautiful eyes.Results All 42 cases with 84 eyes had satisfactory outcome after half a year to 2 years follow-up.The epicanthus scar was conspicuous in the first 6 weeks and it subsided gradually.In the three cases.the hypertrophic scar occurred in the epicanthus,but it softened and became inconspieuous 6 mouths after operation.Conclusion Asymmetrical Z-plasty is a new and reliable method for correction of epicanthus with inconspicuous scar and little chance of recurrence that can be widely used.

Objective To study the change of maternal serum human chorionic gonadotropin(MShCG) in preterm labor and the relationship between hCG and placental pathological changes. Metheds The preterm labor patients were chosen as the research subjects, the normal late-pregnancy women with the same gestational age were chosen as controls. MShCG level were measured by radioimmunoassy (RIA), placental tissue of preterm labor women was examined histologically. hCG in placental tissue was examined by semiquantiative immunohistochemistry. Results MShCG in preterm labor was significantly higher than that of control P

Objective To explore the effect of cisapride combined with polyethylene glycol electrolytic solution on preoperative bowel preparation for patients receiving colorectal cancer operation. Methods One hundred and fifty-two patients received colorectal cancer opera-tion in our hospital from October 2010 to October 2014 were selected. Those who were treated with cisapride combined with polyethylene gly-col electrolytic solution for bowel preparation before operation were assigned to oberservation group(n=83),those who were treated with poly-ethylene glycol electrolytic solution for bowel preparation before operation were assigned to control group(n=69). The side effect after medi-cation, electrolyte concentration and incidence of incision infection between groups after operation were collected and compared. Results The incidence of nausea and vomiting was 7. 23% in observation group,which was significantly lower than 18. 84% in control group (χ2 =4. 64,P=0. 03). The difference of Na+,K+ and Cl- concentration between groups were not significant (t=1. 83,P=0. 07;t=0. 42,P=0. 68;t=1. 86,P=0. 07). The body temperature,leukocyte count and incidence of incision infection after operation in observation group were significantly lower than those in control group (t=2. 68,P<0. 01;t=3. 29,P<0. 01;χ2 =4. 90,P=0. 03). Conclusion Cisapride com-bined with polyethylene glycol electrolytic solution before operation can significantly decrease the incidence of gastrointestinal side effect after medicaiton and incision infection after operation and it is beneficial to recovery for patients with colorectal cancer operation.

Objective To investigate the efficacy and safety of laparoscopic radiofrequency ablation (RFA) therapy for hepatocellular carcinoma.Methods Clinical data of 78 hepatocellular carcinoma patients undergoing laparoscopic radiofrequency in Beijing China-Japan Friendship Hospital from May.2008 to July.2010 were reviewed retrospectively.Age ranged from 31 to 87 years,41 were male and 37 were female.Intraoperative ultrasound-guided needle biopsy was performed and diagnosis of hepatocellular carcinoma was established in all cases before RFA was carried out.Data analysis was performed using software SPSS or OriginPro7.Necrosis,local recurrence of the tumor and the cumulative survival rate were analyzed by Kaplan-Meier test and x2 test.Results The median follow-up time was 16 months after RFA treatment.Tumor size,proximity to intrahepatic vessels and combination with TACE were factors that influence local recurrence.The complete ablation (CA) rate was remarkably higher in tumors ＜ 3 cm than in tumors ＞ 3 -5 cm (90.5％ vs 71.4％,x2 =4.291,P =0.038 ).Tumors adjacent to major vessels had a significantly lower CA rate as compared with those not adjacent to them (63.6％ vs 91.9％,x2 =6.351,P =0.012).The CA rate were 88.9％ in the TACE ± RFA group and 75.0％ in the RFA group ( x2 =1.567,P =0.211 ).The mean overall survival were 48.7 ± 2.4 months,the cumulative survival rate was 86.1％ at 1 year、76.9％ at 2 years、60.3％ at 3 years、51.8％ at4 years and 33.1％ at 5 years.Conclusions Laparoscopic RFA is safe,mini-invasive and effective for unresectable hepatic carcinoma with a favorable long term survival.

Objective To evaluate the association between serum 25-hydroxyvitamin D3 [25 (OH) D3],parathyroid hormone,and arterial stiffness in patients with type 2 diabetes.Methods Serum 25 (OH) D3 and parathyroid hormone(PTH) were determined in a cross-sectional sample of 258 patients aged 30 years and over.Arterial stiffness was assessed by pulse wave velocity(PWV) obtained with a VP-1000 pulse wave unit.Fasting plasma HbA1c,lipid profile,calcium,and high sensitive-C reactive protein were determined.Results (1)The prevalence of vitamin D3 deficiency was high(79.84％) in patients with type 2 diabetes.(2) Those with lowered serum vitamin D3 levels had raised PWV [(1610.76 ± 142.70 vs 1527.95 ± 58.02) cm/s,P＜0.05].(3) Multiple stepwise regression analysis showed that 25 (OH) D3 was an impact factor of PWV risk score,which was independent of age,duration of diabetes,and systolic blood pressure(β =-0.256,P＜0.01).(4) Serum PTH was positively correlated with PWV (r =0.210,P ＜ 0.05) and systolic blood pressure (r =0.229,P ＜ 0.05),but negatively correlated with 25 (OH) D3 (r =-0.153,P ＜ 0.05).Conclusions 25 (OH) D3 deficiency is common in patients with type 2diabetes,and a low serum 25 (OH) D3 level is significantly associated with increased arterial stiffness in these patients.The association of serum PTH with arterial stiffness may result via changes in vitamin D and blood pressure.

Objective To evaluate the value of real-time three-dimensional echocardiography（RT3DE）to predict the long-term response to cardiac resynchronization therapy（CRT）.Methods Twenty-six patients with heart failure were scheduled for CRT.RT3DE was performed before and one year after the pacemaker implantation,and left ventricular（LV）dyssynchrony was defined as the maximum difference（Tmsv 16-Dif）and standard deviation（Tmsv 16-SD）when the minimum systolic volume of 16 segments was reached.Patients were divided into re-sponders and non-responders according to a reduction ≥15 % in LV end-systolic volume（LVESV）after CRT.Results Seventeen patients（65.4 %）were classified as responders.Compared with non-responders,the responders demonstrated a significant increase in LV ejection fraction,and reduction in Tmsv 16-SD.Tmsv 16-SD was a determinant factor for Δ LVESV ≥15%.Tmsv 16-SD 〉3.5% could be employed to evaluate the short-term response to CRT with 80 % sensitivity and 77 % specificity.Conclusions CRT can increase the LV systolic function and synchrony.RT3DE is highly predictive for long-term response to CRT

Objective; To evaluate the efficacy of Twin-block appliance in Class Ⅱ division 1 of adolescents. Methods: Several e-lectronic databases (PubMed, The Cochrane library, Embase, CBMdisk, CNKI, VIP)were searched. Abstract that appears to fulfill the initial selection criteria were selected by consensus and original articles were retrieved. Five Chinese journals were hand searched for possible missing articles. Randomized controlled trials(RCTs) that evaluate the efficacy of Twin-block appliance in Class Ⅱ division I adolescents without any surgical intervention or syndromic characteristics were considered. A comparable untreated control group was required to factor out normal growth changes. The quality of included studies was evaluated according to Cochrane Reviewers Handbook 4.2.6 Meta-analysis was performed by using RevMan 5.0.0 software. Results: Four RCTs including 289 patients were identified. The results of our meta-analysis showed a significant increase on SNB angle, Ar-Gn, Nasolabial angle and Labial-mental fold compared with control group(P<0.05). Whereas overjet, overbite, ANB angle and Ls-E had a significant decrease. In addition, SNA angle and Li-E didnt show statistical significant changes(P>0. 05). Conclusion; In Class II division 1 of adolescents, Twin-block appliance can effectively decrease their overjet, overbite, ANB angle, and induce anterior-posterior growth of mandible. The effect on restrain forward growth of the maxilla was unclear. More RCTs are required to evaluate the efficacy of Twin-block appliance.

Objective:To establish a method for the content determination of tetrahydropalmatine and imperatorin in Yuanhu Zhi-tong tablets by HPLC. Methods:An AKZONOBEL Kromasil 100-5 C18 column (250 mm × 4. 6 mm , 5μm) was used and the mobile phase consisted of methanol and 0. 1% phosphoric acid (52∶48) (adjusting pH to 6. 5 with triethylamine),the flow rate was 1. 0 ml· min-1 at the column temperature of 40℃, the detection wavelength was at 284 nm, and the injection volume was 10 μl. Results:The linear range of tetrahydropalmatine was 0.004 2-0.084 0 mg·ml-1(r=1.000 0). The average recovery was 97.72% with RSD of 1.10%(n=6). The linear range of imperatorin was 0.003 6-0.072 0 mg·ml-1(r=0.999 7). The average recovery was 97.99%with RSD of 0. 96%(n=6). The measurement results of 10 batches were stable and reliable. Conclusion:The method is simple and accurate, which can be used to improve the quality standard.

Objective To evaluate the left ventricular (LV) systolic dyssynchrony after the acute myocardial infarction (AMI) with two-dimensional speckle tracking echocardiography (STE). Methods STE were performed in 65 patients within 72 h of AMI and compared with 60 age- and sex-matched healthy volunteers. The peak longitudinal strain (LS_(peak)) was measured at LV myocardium. LV dyssynchrony was defined as an interval ≥130 ms for the absolute difference in time to peak radial strain for the anteroseptal wall versus the posterior wall (TAS-POST). Size of myocardial infarction (MIS)was confirmed by wall-motion score index (WMSI). Results The LS_(peak) and LV ejection fraction (LVEF) were lower, and WMSI and TAS-POST were larger in AMI patients compared with controls. Forty-two patients had developed LV dyssynchrony (64.62%), and there were strong correlation between LV dyssynchrony (TAS-POST) and LS_(peak), LVEF, and WMSI (MIS). MIS was the most independent predictor for systolic dyssynchrony. Conclusion AMI with normal QRS can induce LV dyssynchrony, which is mainly determined by MIS. STE is a reliable technique for accurate evaluation of LV synchrony.
