Objective:To evaluate the anterior expansion of sacral foramen and decompression of sacral plexus via the lateral-rectus approach (LRA) in the surgical treatment of sacral fractures complicated with sacral plexus injury.Methods:From January 2013 to June 2018, 11 patients were treated at Department of Orthopaedics, The Third Hospital Affiliated to Southern Medical University for obsolete sacral fractures complicated with sacral plexus injury. They were 8 males and 3 females, aged from 17 to 54 years (average, 38 years). According to the Denis classification, all the sacral fractures belonged to Denis Zone Ⅱ. According to British Medical Research Council (BMRC) grading system, the nerve injury was complete damage in 2 cases and partial damage in 9. The mean time from injury to surgery was 6 months (range, from 0.7 to 12.0 months). After the sacroiliac joint was exposed via the LRA, the lumbosacral trunk was exposed and released between iliac vessels and the iliopsoas. Next, the S1 foramen was expanded and the S1 nerve root was released after separation of the median sacral artery and the internal iliac artery. Reduction and fixation of the sacroiliac joint was carried out for patients with unstable sacral fracture. X-ray and CT examinations of the pelvis were performed to evaluate fracture healing and neurological function recovery postoperatively.Results:Of this cohort of 11 cases, operation succeeded in 10 but failed in one whose sacral fracture was found to have completely healed with the S1 foramina totally occluded. The surgical time averaged 110 min (range, from 70 to 220 min) and the blood loss 1, 100 mL (range, from 450 to 2, 800 mL). Postoperative X-ray and CT examinations showed that the sacral foramens were expanded significantly without any complications. The follow-up time averaged 18 months (range, from 12 months to 4 years). By the BMRC grading system at the last follow-up, the neural function was completely recovered in 5 cases, partially recovered in 4 cases and not recovered in one.Conclusion:Significant anterior expansion of sacral foramen and decompression of sacral plexus via the LRA is a viable and effective alternative for treatment of sacral fractures complicated with sacral plexus injury.

Objective To analyze the pregnancy outcomes of fetal tetralogy of Fallot and to explore its prenatal diagnosis and treatment procedures. Methods The clinical data of 63 cases of fetal tetralogy of Fallot (62 cases were singleton and 1 case was one of twin) were collected retrospectively from November, 2013 to November, 2017 in Beijing Obstetrics and Gynecology Hospital. Results (1) Totally, 63 cases out of 46 352 pregnancies were diagnosed fetal tetralogy of Fallot by fetal ultrasonic cardiogram with about 0.136%(63/46 352) occurrence rate, and the mean gestational age was (23±3) weeks. And 50 cases (79%, 50/63) terminated pregnancy by induced labour. (2) Totally, 57 cases (90%,57/63) accepted genetic diagnosis.Eight cases (13%, 8/63) existed chromosome abnormality including 21-trimosy in 6 cases, 18-trisomy in 1 case and 22q11.2 microdeletion syndrome in 1 case; and these 8 cases were determined before 28 gestational weeks. (3) And 13 cases (21%, 13/63) of no fetal genetic abnormality selected to continue pregnancy. Twelve cases underwent full term delivery (5 cases were cesarean section delivery and 7 cases were vaginal delivery). Twelve newborns underwent surgical radical operation on heart malformation and got recovery. One case underwent preterm cesarean section at 35 gestational weeks for one of twin, and the newborn with tetralogy of Fallot was dead. The other the newborns survived and were followed up for tetralogy of Fallot surgery from 1 month to 3 years old after birth and recovered.Conclusions Fetal tetralogy of Fallot mainly is diagnosed by ultrasonic cardiogram in the second trimester. The gestational age of diagnosis may be as early as 15 gestational weeks. Fetal tetralogy of Fallot with no genetic abnormality could underwent radical heart malformation operation after birth. It is necessary to undergo genetic testing on fetal tetralogy of Fallot and prenatal multidisciplinary counseling as well.

Objective To investigate the prevalence of infantile eczema in Uygur and Han nationalities and the relationship between pregnancy factors and 0-6 months infant eczema, so as to provide a scientific basis for formulating preventive strategies. Methods From January-August 2016 in the Xinjiang Autonomous Region People's Hospital of obstetric and follow-up to fill out the questionnaire in 570 pregnant women and their babies as the research object to establish the baseline survey cohort, pregnancy related information to pregnant women, and 6 months (January, March, on maternal June) follow-up, observe the occurrence of infantile eczema a total of 502, successful follow-up to maternal and child. Using nested case-control study, the cohort occurred in 182 cases of infant eczema as case group, will be in the queue without eczema in 320 infants as control group, using multivariate logistic regression analysis of risk factors during pregnancy baby eczema. Results 0-6 months infant eczema incidence rate was 36.25％, the incidence of Uygur infant eczema (20.43％) was significantly lower than that of Han nationality infant eczema incidence (50.19％) (OR=0.45,95％CI:0.35-0.69) P<0.01). Social and economic factors affecting the occurrence of infantile eczema comparison results showed that the ethnic factors and infant eczema, and more prone to eczema than that of Uygur nationality; and Uygur compared mothers influence allergic history of Han infantile eczema more (χ2=7.09, P=0.008). Multivariate logistic regression analysis showed that the mother has a history of atopy (OR=7.17,95％CI:4.15-12.37), mother′s education level (OR=1.91,95％CI:1.51-2.74), the higher the monthly income (OR=2.68,95％CI:2.17-3.33), maternal smoking during pregnancy (secondhand smoke) (OR=2.42,95％CI:1.96-2.97), frequently eating spicy spicy foods during pregnancy (OR=1.94,95％CI: 1.41-2.68) will increase the risk of infant eczema Supplementation of probiotics (OR=0.13,95％CI:0.07-0.25) and vitamin D (OR=0.13,95％CI:0.06-0.26) during pregnancy is a protective factor in the development of infantile eczema. Conclusions Compared to Uygur, Han Chinese infants are more likely occur eczema, and family history of allergies, education, economic income, pregnancy dietand smoking are risk factors for infant eczema. The same risk factors among Uygur and Han ethnic ,but it had a different results. Compared to Han, Uygur pregnant women eating spicy food caused the risk of infant eczema occurrence is higher, but the short period of housing renovation caused the risk of infant eczema occurrence is lower. Therefore, it is necessary to strengthen nutrition andmonitor living environment during pregnancy. Avoiding to eat spicy food and supplying probiotics and vitamin D, it can prevent or reduce the occurrence of infantile eczema.

Objective:To analysis the Mimotopes of the peptide mimics to PGN using online softwares.Methods: Mimotopes of PGN were screened from 12-mers linear phage display peptide library by using anti-PGN McAb and the antigenicity of selected clones was identified by ELISA.The B cell epitopes,T cell epitopes of ′GRWxHxVxWAGL′ were estimated by DNAstar and online softwares.Results: 16 phage clones that bound with anti-PGN McAb were screened from 12-mers linear phage display peptide library.Among these positive clones,phage clones No.39 shared the conserved sequence:WxHx……AGL found in previous clone No.31(ATWxHxLxSAGL),which provoked an effective protective immunity against infection with S.aureus.To enhance the stability of the conformation as well as adding biotin on the N-ter-minal as a tag,the sequences ′39′ were redesigned and synthesized by adding S(serine)A(alanine) and GG(glycine)on the C-terminal of origin sequence(named SP39).Next,we estimated or predicted antigenic epitopes,T cell epitopes and scores binding to MHC of these peptides by using DNASTAR and online softwares(http://bio.dfci.harvard.edu/Tools/antigenic.pl,www.syfpeithi.de,http://www.darrenflower.info/mhcpred),indicating that SP39 contains sites bound both mice and human MHC.The sequences ′WxHxVxW-′ may be antigenic epitope as SP39,which contains a T cell epitope.Our results showed that both SP39 could bind to both anti-PGN McAb and a polyclonal antibody against S.aureus.Moreover PGN could inhibit the binding of SP39 to the anti-PGN McAb.These data indicated that SP39 mimic to epitopes on PGN.Conclusion: SP39(GRWxHxVxWAGLAGGS) probably display the mimotopes of PGN.
