Objective To investigate the indications and surgical approaches of full-thickness eyelid reconstruction with superficial temporal artery island flap and oral mucosa free grafting,and evaluate the safety and efficacy.Methods A total of 13 eyes of 13 patients with wide full-thickness eyelid defect were treated by the eyelid reconstruction with superficial temporal artery island flap and oral mucosa free grafting.The defect area was(33.67?8.35) mm?(16.44?4.45) mm and the size of island flap was(38.56?8.99)mm?(18.44?4.00)mm.Eight cases were treated with oral lip mucosa grafting,while the other 5 with hard plate muco-periosteal free grafting.Follow up was conducted for 6 to 24 months. Results The flaps were clinically viable in 10 cases and partially viable in 2.One was inviable for venous circumfluence failure,and a successful free skin grafting was conducted 3 months postoperation.All the grafted oral mucosa survived.Five cases underwent the second surgery to thin the island flap,among whom 3 were performed eyelid suspension with the frontal muscle.The survived flaps were similar to skin in colour,soft in nature,and could effectively protect the eyeballs. Conclusion The superficial temporal artery island flap along with oral mucosa free grafting works well in wide full-thickness eyelid reconstruction.

Objective To summarize the complications of the single-port transumbilical laparoscopic pyeloureteroplasty.Methods From August 2009 to December 2014, 162 surgical procedures were performed in our institute with the single-port transumbilical laparoscopic pyeloureteroplasty.Medical records of each procedure were retrospectively evaluated.139 patients were male and 23 female, aged from 1 month to 14 years and the median age of 2 years.127 patients were operated on the left side and 32 on the right side.3 patients were operated on the bilateral side.All children were supplemented with preoperative ultrasound, renal dynamic imaging and MRU to identify the ureteropelvic junction obstruction.Intraoperative and postoperative complications were graded according to the Satava and Clavien classifications respectively.Major complications were defined as Satava grade Ⅱ or higher, and Clavien grade Ⅲ or higher.Results There was no injury of vascular or visceral organs and no blood transfusion, and there was no serious intraoperative complications.One hundred and forty-three cases were followed up, and 23 cases (16.1％)presented with postoperative fever (＞ 38 ℃C) (Clavien Ⅰ), 2 cases (1.4％) with urinary extravasation diagnosed by perirenal fluid collection(Clavien Ⅰ).All these cases recovered after being given symptomatic treatment.7 cases (4.9％) presented with postoperative repeated urinary infection (Clavien Ⅱ).5 cases received postoperative reoperation due to the obstruction of the anastomic site (Clavien Ⅲ b), and 2 cases were under debridement as the greater omentum was drawn out along with the negative pressure drainage tube(Clavien Ⅲ a).In summary, the incidence of severe postoperative complications was 4.9％.Conclusions Though there existed some postoperative complications of the single-port transumbilical laparoscopic pyeloureteroplasty, the incidence of serious complications was low and the overall prognosis could be good.

OBJECTIVETo investigate diagnostic efficacy of transvaginal three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy) in assessing tubal patency with chromolaporoscopy.

METHODSA total of 157 infertile women underwent 3D-HyCoSy to evaluate tubal patency. Among these patients, 39 patients were also examined by chromolaporoscopy. The concordance of the two clinical assessment methods was analyzed by the Kappa coefficient test.

RESULTSAmong the 306 oviducts examined by 3D-HyCoSy, 99 (32.4%) were patent, 126 (41.2%) partially obstructed, and 81 (26.5%) completely obstructed. Diagnostic results with 3D-HyCoSy were not statistically different from those obtained in the 39 women (78 oviducts) who also underwent chromolaporoscopy, and the two methods showed a high concordance (k=0.747, P=0.000). The 3D-HyCoSy procedure had a sensitivity of 84.8% (28/33), a specificity of 96.2% (25/26), and positive and negative predictive values of 93.3% (28/30) and 86.2% (25/29) respectively.

CONCLUSIONTransvaginal 3D-HyCoSy can accurately reveal the spatial path and morphology of the oviduct and is a safe and effective method to evaluate tubal patency.

Objective To investigate the effect of peroxisome proliferator-activated receptor γ (PPARγ) agonist pioglitazone on white matter lesions and spatial memory function in chronic hypertensive rats.Methods Thirty-six male Sprague-Dawley rats were randomly divided into a sham operation group (n =6),a hypertensive group,(n =15),and a pinglitazone group (n =15).A model of stroke-prone renovascular hypertensive rat (RHRSP) was induced by the two-kidney two clip method in the hypertensive group and pioglitazone group.At 8 weeks after procedure,the rats were administered intragastrically.10 mg/(kg · d) pioglitazone was given in the pioglitazone group and an equal volume of saline was given in the hypertensive group.Blood pressure was monitored via caudal artery every 2 weeks before procedure,before administration,and after administration,respectively.After 12 weeks of continuous administration,Loyez staining was used to observe the degree of leukoaraiosis,and Morris water maze test was used to detect spatial memory function.Results After modeling,the blood pressure of RHRSP increased gradually.It was significantly higher than the sham operation group (all P =0.001).There was no significant difference in blood pressure between the hypertensive group and the pioglitazone group (P =0.897).The Morris water maze test showed that escape latencies of the sham operation group and the pioglitazone group were significantly shorter than the hypertensive group (all P ＜0.05).The numbers of crossing hidden platform in the 3 groups of rats were 5.200 ± 1.798,4.560 ± 1.592,and 2.333 ± 1.978 times,respectively.There were significantly differences (F =8.143,P =0.001).Both the sham operation group and the pioglitazone group were significantly more than the hypertensive group (all P ＜0.05).Loyez staining showed that the grades of white matter lesions in corpus callosum of the sham operation group,the hypertensive group,and the pioglitazone group were 0.333 ± 0.516,2.600 ± 0.507,and 0.500 ± 0.522,respectively.There were significantly differences among the 3 groups (F =25.652,P =0.000).The grade of the sham operation group and the pioglitazone group was significantly lower than the hypertensive group (all P＜ 0.05).Conclusions PPARγ agonist pioglitazone may protect the spatial memory function by relieving white matter lesions of the chronic hypertensive rats.

Objective To compare the analgesic efficacy and safety of the sole local anesthetic ropivacaine with the combination of both local anesthetic ropivacaine and opioidergic analgesic sufen-tanil given epidurally on the labor pain control.Methods After institutional review board approval and patient consent,a total of 481 nulliparas requesting epidural labor analgesia were randomized into two groups:a sole local anesthetic group (0.125% ropivacaine,group R)and a combination of local anesthetic and opioidergic analgesic group (0.125% ropivacaine+0.3 μg/ml sufentanil,group RS). Analgesic efficacy was measured using numerical rating scale (NRS)of pain and maternal visual ana-logue scale (VAS)analgesia satisfaction with regard to the first and the second stage of labor.Anal-gesic safety was measured with the Bromage scale of maternal safety and epidural labor analgesia re-lated side effects,as well as fetal safety including Apgar scoring and umbilical cord artery blood gas a-nalysis.Results A total of 346 participants completed the study,with 1 64 and 182 women in each group R and RS,respectively.The median NRS pain score during the first stage of labor was signifi-cantly lower in the combination group (2.2,IQR:1.8-2.7 )comparing to the sole local analgesic group (2.4,IQR:2-2.8)(P <0.001).No significant difference was observed in NRS pain score dur-ing the second stage of labor.Patients in both groups were rated the same VAS satisfaction of analge-sia.Patients in the sole local analgesic group experienced fewer side effects than those in the combina-tion group (37.7% versus 47.2%,P =0.082).The incidence of 1-min Apgar≤7 was lower in the sole local analgesic group 2 (1.2%) than the combination group 10 (5.5%) (P < 0.05 ). Conclusion The sole local anesthetic ropivacaine produces a comparable labor analgesic effect as the combination of both local anesthetic ropivacaine and opioidergic analgesic sufentanil but the former has less maternal side effects,and less incidence of lower 1-min Apgar scoring.

Objective To detect the ocular fundus hemodynamic changes in patients with rhegmatogenous retinal detachment before and after the scleral buckling procedure by Heidelberg retina flowmeter,and analyse the related influential factors. Methods Heidelberg retina flowmeter was employed to measure the volume,flow and velocity in retinal vessels of the impaired eyes in 47 patients with unilateral rhegmatogenous retinal detachments 1 day before and 1 week,1 month and 3 months after scleral buckling procedure.The contralateral eyes were served as controls. ResultsThere were significant differences in the volume,flow and velocity of retinal vessels between the impared eyes and controls preoperation and postoperation(P

Objective To observe the postoperative changes of diplopia and eyeball movement disorder in patients with orbital fracture. Methods The clinical data of 62 patients with reconstructive surgeries for orbital fracture were retrorespectively analyzed.The position,range of fracture and incarceration of extraocular muscles were determined by CT scanning.The eyeball movement and diplopia were examined and recorded pre-operation,3,6 and 12 months after operation,respectively. Results Among the 62 cases,23 were simple orbital wall fracture and the other 39 were complex orbital fracture.Eighteen of the patients with simple orbital wall fracture had diplopia and 19 had eyeball movement disorder of Ⅰ degree or Ⅱ degree before operation.Twelve months after operation,5 had diplopia ofⅠ degree or Ⅱ degree,and 5 had eyeball movement disorder of Ⅰ degree.For those with complex orbital fracture,36 had diplopia and 38 had eyeball movement disorder.Twelve months after operation,29 had diplopia(III degree diplopia in 6) and 22 had eye movement disorder.Among the 12 patients with complex orbital fracture who received operation within 3 weeks after trauma, only one had III degree diplopia,while 5 of the 23 with complex orbital fractures repaired 3 months after trauma had III degree diplopia. Conclusion Surgical management can effectively improve diplopia and eyeball movement disorder resulted from orbital fracture.Earlier treatment is superior to later treatment in regard with the effect of surgical intervention.

Objective To investigate new cases of endemic cretinism in high-risk areas of Inner Mongolia, the prevalence of endemic goiter, the implementation of comprehensive measures, and to provide scientific basis for developing control strategies against iodine deficiency disorders (IDD). Methods In 2007 and 2008, a search for new cretin cases was conducted among children under the age of 10 in 11 historical serious epidemic cretinism prevalent areas of Songshan district, Keshiketeng qi, Kalaqin qi, Zhalaite qi, Zhuozi county,Liangcheng county, Qingshuihe county, Helin county, Dongsheng district, Zhungeer qi and Yinjinhuoluo qi. Three to 5 towns were selected in each qi(county, district) and 3 to 5 village primary schools were selected in each town.One hundred and twenty to 200 children aged 8 to 10 were selected in each school to inspect thyroid by B ultrasound and palpation and to test intelligence and urinary iodine. Two villages were selected in each town and 30 households were selected to determine urinary iodine of housewives and salt iodine. Results A total of 56 cases of suspected cases of endemic cretinism were found from the 11 counties but no case was confirmed. The goiter rate of children aged 8 to 10 was 5.2% (309/5922) by palpation and 4.3% (252/5922) by B-ultrasound. The median urinary iodine of children aged 8 to 10 was 241.5 μg/L, and urinary iodine was 100 to 300 μg/L, accounted 65.9%(3901/5920). Median urinary iodine of the 9 Qis(counties, districts) was in the range of 200 and 300μg/L.Higher than 5% of the 11 Qis(counties, districts) with urinary iodine lower than 50 μg/L was zero. Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 1. The median urinary iodine of housewives was 225.6 μg/L, and lower than 50 μg/L accounted for 2.2%(35/1597). Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 4. A total of 2109 households were investigated and 97.45%(2055/2109) of them ate iodized salt and 2.55%(54/2109) of them ate non-iodized salt. Conclusions In the 11 investigated counties, goiter rate of children has decreased to less than 10%, and no new cretin was found. It could be concluded that the fulfillment of prevention and control of IDD is effective. The iodine nutrition of children and women of childbearing age is in an adequate level. The coverage rate of iodized salt has maintained at a higher level, the sales network is sound, the salt price is reasonable and salt is easy to get and the children's intelligence is protected effectively. But, the health education about IDD is still weak, need to be reinforced.
