Inflammatory Bowel Disease(IBD) is concerned with heredity,dysimmunity,environment and others,its characterized by chronic or relapsing inflammation within the gastrointestinal.IBD including two independent disease ulcerative colitis and crohn′s disease.In recent years with the incidence of IBD increased year by year,more women in reproductive age facing drug treatment.This article elucidated the effect of IBD and its treatment on perinatal.

Objective To analyze retrospectively the results of closed reduction and static transarticular fixation with unilateral external fixators in the treatment of severely comminuted distal radius fractures caused by high-energy injuries. Methods From June 2000 to June 2003, 20 patients with 24 severely comminuted distal radius fractures were treated with closed reduction and static transarticular fixation with unilateral external fixator. The injuries involved 16 males and 4 females, the age of the patients was from 15 to 48 years (average 33.4 years). All fractures were classified as Frykman's type Ⅷ or AO type C3. The operative technique consisted of reduction of the fractures by manipulation or assisted with the external fixator, then fixed them statically. The mean duration of the union was 7.4 weeks (ranged from 6-8 weeks). After the fixator removal, the patients were encouraged to proceed for the rehabilitations, such as the elbow flexion-extension, radial abduction, ulnar adduction, and the pronation as well as the supination of the forearm. Results All patients were available at the final follow-up, the mean duration was 16 months (range, 6-42 months). At the last examination, the radiological manifestations revealed excellent in 21 fractures (17 patients) and good in 3 (3 patients) according to the Sarmiento scoring system (modified by Stewart); and the functional results displaied excellent in 16 (13 patients), good in 6 (5 patients) and fair in 2 (2 patients) according to Gartland-Werley functional assessment system. There were only 2 cases of superficial pin site infection cured with oral antibiotics and local care with mild disinfectants. 7 obvious defect of mataphysis occurred in 5 patients, but the fractures united simultaneously without any additional treatment. And there was no any complication, such as pin tract infection, fixator loosening, iatrogenic fracture and injury of the superficial radial nerve. Conclusion The technique of closed reduction by manipulations or external fixators combined with static transarticular fixation plus unilateral external fixators is an effective method for the treatment of severely comminuted distal radius fracture caused by high-energy injuries, such as falling from the height. It is unnecessary to apply supplementary bone grafts to promote bone healing. The complications can be avoided by selecting the right sites for the insertion of the pins, which is beneficial for the hand to mobilize earlier after operation.

Objective To retrospectively analyze the results of closed reduction and static trans-articular fixation with unilateral external fixators in the treatment of unstable distal radius fractures.Methods From June 2000 to March 2005,45 patients with 50 unstable distal radius fractures were treated with closed reduction and static transarticular fixation by unilateral external fixators.Their average age was 44.8 years(15 to 78 years).All the fractures were classified with AO-scheme.There were five A3-fractures,four B3-fractures,three C1-fractures,nine C2-fractures and 29 C3-fractures in 24 cases.Follow-ups lasted from 8 to 48 months(averaging 20 months).Results The time of bone healing was 6 to 8 weeks(averaging 7.6 weeks).At the latest follow-up,the radiological outcomes were excellent in 42 fractures(39 patients)and good in eight fractures(six patients)according to the Sarmiento rating system modified by Ste wart et al.The functional results included 37 excellent cases(34 patients),nine good ones(eight patients)and four fair ones(three patients)according to the Gartland-Werley assessment.There were only four cases of superficial pin site infection settled with oral antibiotics and mild disinfectants.Conclusions Closed reduction by manipulation and static transarticular fixation with unilateral external fixators is an effective method to treat severely comminuted distal radius fractures caused by high-energy injury.Radial nerve injury and iatrogenic fracture of the 2nd metacarpal bone can be avoided,pin tract infection and pin loosening can be decreased,and early postoperative mobilization of hand can be facilitated by insertion of external pins at appropriate sites.It is unnecessary to apply supplementary bone grafting to promote bone healing.

Objective To compare the clinical effects of HC video laryngoscope and fiberoptic bronchoscope (FOB)in guidance of endotracheal intubation for patients undergoing cervical surgery.Meth-ods A total of 50 patients (ASA I or II)with cervical vertebra injury,nerve root cervical spondylopathy or cervical spondylotic myelopathy in the first affiliated hospital of Wenzhou medical university were selected, all of whom were undergone selective cervical operations between March 2014 and June 2015.The patients were randomly divided into two groups (n =25):HC video laryngoscope group (group H)and FOB group (group F).After induction of anesthesia,HC video laryngoscope and FOB were used for tracheal intuba-tion.⑴ Intubation time and success rates of intubation were recorded,and visual analogue scale (VAS) was used to evaluate the difficulty of intubation;⑵ Mean arterial pressure (MAP),heart rate (HR),and rate-pressure product (RPP)before incubation (Tb),immediate after intubation (T0),and 1min after in-cubation (T1)were recorded;(3)Intubation-related complications were recorded.Results ⑴ The dura-tion of intubation (19.7 ±7.1 )s in the group H was significantly shorter than that of group F (51.9 ± 19.2)s (P <0.05).The one-time success rate of intubation in group H (92%)was higher than that of group F (64%),with statistically significant differences (P <0.05).Intubation was easier in group H (P <0.05).⑵ MAP,HR and RPP of group H at T0 were higher than those of group F.And at T1,there were no statistical differences between groups in MAP,HR and RPP (P >0.05).⑶ The incidence of complications (sore throat)was lower in group H (P <0.05).Conclusions Compared to FOB,HC vid-eo laryngoscope-guided selective cervical operation has the characteristics of higher success rate of intubat-ion,shorter operation time,and easier operation,more stable hemodynamics and lower incidence of intuba-tion complications.Therefore,HC video laryngoscope is a safe and effective method in the intubation for pa-tients undergoing cervical surgery.

Objective To investigate the clinical outcomes of different managements of complete rupture of the deltoid ligament associated with supination-external rotation ankle fracture.Methods From January 2010 to June 2014,33 cases of complete rupture of the deltoid ligament associated with supination-external rotation ankle fracture were treated with open reduction and internal fixation.According to the different managements of the complete rupture of the deltoid ligament,the patients were divided into 4 groups:9 cases in the non-repair group,7 cases in the superficial layer repair group,9 cases in the deep layer repair group,and 8 cases in the complete repair group.All the patients took anteroposterior,lateral and gravity stress radiographs preoperatively and postoperatively.The 4 groups were compatible in preoperative general data (P ＞ 0.05).The 4 groups were compared in terms of operation time,medial clear space and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score.Results All the patients were followed up for 6 to 18 months (average,13.7 months).All wounds healed at the first stage without any infection.All fractures united primarily after 3 to 9 months (average,4.7 months).The operation time for the superficial layer repair group was significantly longer than for the non-repair group,but significantly shorter than for the deep layer repair and the complete repair groups (P ＜ 0.05).In gravity stress radiographs,there was no significant difference in medial clear space among the 4 groups (P ＞ 0.05),but there were significant differences before and after operation in the 4 groups (P ＜ 0.05).The postoperative AOFAS ankle-hindfoot score in the repair groups was significantly higher than in the non-repair group and the superficial layer repair group(P ＜ 0.05).Conclusion To achieve satisfactory outcomes for patients with complete rupture of the deltoid ligament associated with supination-external rotation ankle fractures,anatomic open reduction and rigid internal fixation is necessary,and repair of the deltoid ligament,especially its superficial layer,is a valuable contribution.

Objective To elucidate the efficacy and safety of transcatheter closure of secondary atrial septal defect (ASD) with Amplatzer septal occluder (ASO) in people over 50 years of age. Methods Retrospective comparison of 41 patients (14 males, 27 females) with ASD over 50 years of age ranging from 50 to 75(mean age 55.5?7.6, elder group) was conducted with 132 patients younger than 50 years(control group). After diagnosis of ASDs and evaluation of pulmonary artery systolic pressure and right atrial and ventricular dimensions by transthoracic echocardiography (TTE), all patients underwent transesophageal echocardiography (TEE) for complete assessment of ASD size, margins and anatomic relationship of the defect before closure of ASD. Each case was treated with ASO through the percutaneous transcatheter procedure under fluoroscopy and TTE or TEE. Early follow up(3 months) by echo was taken after the intervention. Results There was no difference of mean defect diameter measured by TEE and the balloon-stretched defect diameter of the ASDs between 2 groups. Pulmonary artery pressures in elder group were higher than those in younger group(P

Objective To study the injuries of avulsion and severance of upper extremity caused by flexion and rotation and application of tissues of chest side and back in functional reconstruction of the upper extremity. Methods The primary or fosterage replantations were performed from 2000 July to 2003 September for 6 cases of the injuries of avulsion and severance of upper extremity caused by flexion and rotation. After the operation, the shoulder joint was immobilized at abduction of 90 degrees and elbow joint was fixated at inflexion of 100 degrees. 4 weeks later, the fixation was removed and the regular functional training was started. Results Follow-ups ranging from 3 months to 2 years revealed that all the cases of replantation were successful. After operation, the shoulder joint could abduct 50?～90?, anteflect 50?～70?, extend backwards 20?～30?, and adduct 20?～40?. The elbow joint could flex 100?～140?and extend -20?～0?. 3 months after reconstruction, the muscle strength of elbow flexion recovered to Ⅳ～Ⅴdegrees. Conclusion Application of tissues of chest side and back to repair avulsion and severance of upper extremity stage by stages and layer by layer is an ideal method to resolve the contradiction between wound coverage and functional reconstruction because it can restore both the function and appearance.

Objective To detect the expression of interlenkin-22 (IL-22) and relative CD4+ T cell subsets in patients with ulcerative colitis (UC),and to explore their roles in the pathogenesis of UC.Methods Thirty-five adult UC patients were enrolled in this study and 35 healthy subjects were taken as control.Plasma IL-22 level was quantified by ELISA.The percentages of Th1,Th17 and Th22 cells in peripheral blood were determined by flow cytometry.The relationships of these results and disease activity were analyzed.Results Plasma IL-22 levels in UC patients [ (354.12±104.22 ) pg/ml ]were significantly higher than that of healthy controls ( P＜0.05 ),and the levels increased significantly in severely active patients.The percentages of Th17 cells in UC patients [ (2.36±0.94) ％ ]were elevated compared to healthy controls ( P＜0.05 ),and the percentages increased significantly in moderately active and severely active patients.The percentages of Th22 cells in UC patients [ (2.27±0.87 ) ％ ]were elevated compared to healthy controls (P±0.05),and the percentages increased significantly in severely active patients.The percentage of Th1 cells was not significantly different between UC patients and normal controls.ConclusionOur resuits demonstrate elevated IL-22 correlated to Th17 and Th22 cells may play an important role in the immunopathogenesis of UC.

Objective To investigate the clinical efficacy of a new minimal incision suture technique in repair of acute close rupture of Achilles tendon.Methods From August 2008 through October 2014,134 patients with acute close rupture of Achilles tendon were treated with a self-designed minimally invasive suture technique at our institution.They were 130 men and 4 women,with an average age of 37.4 years (range,from 18 to 52 years).The left side was injured in 93 patients and the right side in 41.The interval from injury to surgery was 1 to 7 days (average,2.5 days).The tendon rupture was located at 4.5 to 6.3 cm proximal to its insertion in 133 patients,and at 1.2 cm in one.With the ankle held in full plantar flexion,a 1.0 to 1.5 cm transverse incision was made over the palpable defect.Forceps were then used to mobilize the tendon from beneath the paratenon.The safe puncture site was determined by course and distribution of the sural nerve indirectly located by magnetic resonance imaging (MRI).Ethicon MB66 nonabsorbable suture was passed diagonally through the tendon bulk under epidural puncture needle guidance.The proximal and distal ends of the suture were tied together and buried.The tendon ends were apposed through the transverse incision.Postoperative individual rehabilitation was established based on pathological differentiation for tendon tissue.Results All the patients were followed up for 8 to 48 months (average,19.6 months).All the wounds healed at the first stage.No complications happened related to incision.The nervus suralis was injured in 3 patients;tendon re-rupture occurred in 4 patients,3 of whom received re-operation and one of whom conservative treatment.Their American Orthopaedic Foot and Ankle Society (AOFAS) scores averaged 99.6,giving a good to excellent rate of 100％ (133excellentcasesandonegoodcase).According to the Arner-Lindholm evaluation criteria,ankle function was excellent in 99 cases,good in 34 ones and poor in one,giving a good to excellent rate of 99.3％.Conclusion The new minimal incision suture technique is worthy of promotion in repair of ruptured Achilles tendon,because it is simple and reliable,does not interfere with the blood circulation to the Achilles tendon,prevents such complications as sural nerve injury and recurrent rupture,and leads to little adhesion and quick functional recovery.

Objective To study the effect of repeated rectal exposure of low -dose simian immunodeficiency virus on the systemic cellular immunity in monkeys .Methods Eight 3-to 4-year old rhesus macaques ( Macaca mulatta) (male:female 1:1) were used in this study.The monkeys were inoculated with 10 TCID50 SIVmac239 virus through rectum twice a week for consecutive 6 weeks to establish a multiple rectal exposure model of SIVmac 239 virus infection.Then, plasma viral load, CD4+ T cell count, T cell subsets and IFN-γsecretion of the experiment monkeys were determined . Results Low-dose SIVmac239 virus induced some changes in the immune system through the rectal mucosa , but didn’t induce typical infection.Repeated rectal mucosal low-dose virus exposure can activate the cellular immune system .
