Objective:To compare the effect of laparoscopic uterine isthmus cerclage and transvaginal uterine isthmus cerclage in the treatment of cervical incompetence at non pregnant condition.Methods:A total of 63 patients with cervical incompetence from May 2013 to May 2015 in our hospital were enrolled in the retrospective analysis,all the enrolled patients had naturally conceived single birth with complete data after laparoscopic uterine isthmus cerclage or transvaginal uterine isthmus cerclage and were divided into two groups according to two different surgical methods for uterine isthmus cerclage to compare the clinical effect.30 patients treated with laparoscopic uterine isthmus cerclage were,in the research group and the other 33 patients treated with transvaginal uterine isthmus cerclage were in the control group.Results:The treatment success rate of research group (96.67％) was significantly higher than that of the control group(51.52％) (P ＜ 0.05).The research group had got a longer average pregnancy period than control group (P ＜ 0.05).Postoperative abortion rate (3.33％) and preterm birth rate(10.00％) of research group were obviously lower than the control group (48.48％,30.30％)(P＜0.05).The term infant rate of research group (86.67％) was higher than control group (21.21％) (P ＜0.05).The operation time((37.27 ± 1.93 min) and hospital stay(5.17 ±0.38 d) of the research group were less than the control group(P＜0.05).The bleeding amount in surgery of research group(13.13 ±1.57ml) was significantly lower than the control group(31.61 ± 1.87 ml) (P ＜ 0.05).The complication rate of observation group was 0,and the control group was 18.18％.The difference was significant(P ＜ 0.05).Conclusions:Laparoscopic uterine isthmus cerclage in treatment of cervical imcompetence at non pregnant condition has better clinical effect than transvaginal uterine isthmus cerclage.It has higher security and feasibility.It is worth clinically promoting.

Objective To evaluate the effect of weight-bearing alignment training (WBAT) in correcting anterior pelvic tilt in children with cerebral palsy.Methods Twenty-seven children with cerebral palsy and anterior pelvic tilt were recruited and randonly assigned to a WBAT group,a strengthening group and a standing group,each of 9.In addition to routine medication and rehabilitation training,the 3 groups received WBAT,strengthening training or standing training respectively for 20 minutes a day,5 times a week for 4 weeks.Before and immediately after the treatment,the subjects' anterior superior iliac spine-posterior superior iliac spine angles (ASIS-PSIS angles) were assessed along with their anterior-posterior angles (A-P angles) and distances in a 1-minute walk test.Results The WBAT group showed significant improvement in their average ASIS-PSIS angle (to 18.61 ± 3.13°),A-P angle (to 23.31±3.81°) and the distance in the 1-minute walk test after the treatment.The standing group had significant progress in improving their A-P angles (to 24.48±4.33°),and the strengthening group had significant improvement in the distance walked in the 1-minute walk test.The average improvements in the ASIS-PSIS angle and walk distance in the WBAT group were significantly better than in the other 2 groups.Conclusion WBAT is superior to strengthening and standing training in improving the ASIS-PSIS angle,A-P angle and walking ability of children with cerebral palsy and anterior pelvic tilt.

Objective To analyze the result and adverse reactions of radiation therapy in patients with pelvic recurrence following cervical cancer postoperative.Methods A retrospective analysis of 147 patients with pelvic recurrence after surgical treatment of cervical cancer in the Fourth Hospital of Hebei Medical University from August 2004 to December 2016 was performed.All patients received radiotherapy with or without chemotherapy.According to different clinical factors and pathological factors,Logistic regression analysis was used to analyze the factors influencing radiotherapy outcomes in patients with pelvic recurrence after cervical cancer surgery.The Kaplan-Meier method was used to analyze the survival rate,and the corresponding survival curve was drawn.The survival rate and prognosis related factors were compared by using the log-rank test.The COX proportional hazards regression model was used for multivariate analysis of statistically relevant factors in univariate analysis.After treatment,toxicities were analyzed using chi-square test.Results The median follow-up time was 33.2 months.95％ of the patients completed radiation therapy with a dose of ≥ 67 Gy (median radiotherapy dose),and 91 patients (61.9％) had complete remission (CR).The 5-year local control (LC),progression-free survival (PFS),distant metastasis-free survival (DMFS),and overall survival (OS) were 63.6％,56.0％,73.9％,and 55.0％,respectively.Univariate logistic regression analysis showed that FIGO staging (stage 0-ⅠB and ⅡA-ⅡB),pelvic sidewall involvement,and recurrent tumor volume were associated with complete remission (P＜0.05).Multivariate statistical analysis found that FIGO staging and pelvic sidewall invasion were independent factors influencing the efficacy and survival of patients with pelvic recurrence after cervical cancer surgery (P＜0.05).Patients with pelvic wall invasion after cervical cancer surgery had a higher incidence of ≥ grade 2 proctitis than those without pelvic walls involved,which were 26.9％ and 16.7％,respectively.Conclusions This study shows that after the surgical treatment of cervical cancer patients with pelvic recurrence can be tolerated by toxicities after radiation therapy.In addition,the incidence of toxicities in patients with pelvic wall invasion was significantly higher than those without pelvic wall invasion.Preoperative staging and the pelvic wall involvement are independent influencing factors influencing the effect of radiotherapy and long-term prognosis in patients with pelvic recurrence after cervical cancer surgery.

Objective:To determine the influences of structural changes after valgus impacted femoral neck fracture on hip range of motion (ROM) so as to provide evidence for clinical judgment of whether reduction is necessary or not in the internal fixation of such fractures.Methods:1. 3D reconstructions of the CT hip scans were performed for the 73 patients who had been treated at Department of Orthopaedic Surgery, Shanghai Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University for valgus impacted femoral neck fractures from January 2019 to April 2019.The femoral neck-shaft angle, anteversion angle, femoral offset, axial alpha angle, lateral center edge angle (LCEA), anterior center edge angle (ACEA) and center displacement were measured and compared between the affected and healthy sides to determine the influences of the fracture on the above indexes. 2. Hip motions (flexion and MIR-90°) were simulated on bilateral sides to determine the influences of structural changes after fracture on hip ROM using stepwise regression and Logistic regression. 3. The distribution of femoral-acetabular contact points on the femoral side was observed in simulation of hip flexion to detect the potential area for femoracetabular impingement (FAI) induced by the fracture displacement.Results:1. The valgus impacted femoral neck fractures had significant influences on femoral neck-shaft angle, anteversion angle, femoral offset and axial alpha angle. Compared with the healthy side, on average, the femoral neck-shaft angle increased by 5.1°, anteversion angle decreased by 6.5°, femoral offset decreased by 8.2 mm and axial alpha angle increased by 9.7° on the affected side, showing significant differences ( P<0.05).The displacements of the femoral head center averaged 9.2 mm. There was no significant difference in LCEA or ACEA between the affected and healthy sides ( P>0.05). 2. Compared with the healthy side, on average, the simulated hip flexion decreased significantly by 27.0° and the hip MIR-90° decreased significantly by 20.3° on the affected side after fracture ( P<0.05). Regression analysis showed that femoral anteversion angle, ACEA and displacement of the femoral head center had a significant influence on hip ROM, especially the anteversion angle. When the anteversion angle decreased by more than 7.1°, the hip flexion would decrease by at least 20%. 3. The points of FAI distributed more widely on the fracture side. Compared with the healthy side, the impact points extended outward and upward in hip flexion and extended inwardly in hip MIR-90° on the affected side. Conclusions:After a valgus impacted femoral neck fracture, if the femoral anteversion angle has been decreased by more than 7.1°, the hip ROM can be greatly influenced and the points of FAI can be distributed more widely. Therefore, reduction should be recommended before internal fixation of the fracture.

OBJECTIVE: To explore molecular etiology and clinical characteristics of two pedigrees affected with hereditary factor VII(FVII) deficiency. METHODS: The nine exons and flanking sequences of the F7 gene of the probands were amplified by PCR. The amplicons were analyzed by direct sequencing. Suspected mutations were subjected to SWISS-MODEL modeling and analysis of protein structure change by Pymol software and conservation of amino acids across various species. RESULTS: For proband of pedigree 1, the prothrombin time (PT), FVII activity (FVII:C) and FVII antigen (FVII:Ag) were 36.3 s, 3%, 53.56%, respectively. Sequencing revealed a compound heterozygous variants of c.80_81delCT and c.1371G>T(p.Arg439Ser). His son carried a heterozygous c.1371G>T (p.Arg439Ser) variant. For proband of pedigree 2, the PT, FVII:C and FVII:Ag were 22.3 s, 4%, 1.58%, respectively. Sequencing has revealed a compound heterozygous c.278G>T(p.Arg75Met) missense variant in exon 3 and c.1278T>G (p.His408Gln) in exon 9 of the F7 gene. His mother and son both carried a heterozygous c.278G>T(p.Arg75Met) variant. Three-dimensional simulation and homology analysis revealed that the p.Arg439Ser and p.Arg75Met can respectively alter part of hydrogen bonds and two highly conserved amino acids. CONCLUSION Two novel heterozygous missense variants of the F7 gene [c.1371G>T(p.Arg439Ser) and c.278G>T(p.Arg75Met)] probably account for the decrease of factor VII in the two pedigrees.
