Objective To comparative the expression of suppressors of cytokine signaling 3 (SOCS3) in placental tissues between premature delivery and term delivery,and to evaluate the significance of SOCS3 in premature-delivered placental tissues.Meth ods Retrospective analysis was made on 30 patients who had spontaneous premature delivery and 30 pregnant women with normal delivery from February 2013 to October 2013 in our hospital.Reverse transcription and polymerase chain reaction (RT-PCR) was used to detect the mRNA expressions of SOCS3,interferon-α(IFN-α),and interleukin-10 (IL-10).Western-blot was used to detect protein expression of SOCS3,and to analyze the balance of Th1/Th2.Results PCR detection showed that SOCS3-mRNA in the control group was significantly lower than that in the experimental group (P ＜ 0.01).Western-blot test showed that SOCS3 protein expression in the control group was significantly lower than that in the experimental group (P ＜ 0.01).The expression of SOCS3 gene was consistent with its protein expression.PCR detected the significant increase of IFN-α with the secretion of Th1 cytokine,significant decrease of IL-10 with secretion of Th2 cytokine (P ＜ 0.05),and the balance deviation of Th1/Th2 toward Th1.Conclusions SOCS3 is associated with premature delivery,which mechanism might be involved in regulation of the immune balance through janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathways.

Objective:To evaluate the relationship between breast reconstruction and postoperative complications by meta-analysis.Methods:Through a defined search strategy, related literature was collected in databases from PubMed, MEDLINE, EMBASE, Cochrane, CNKI, Wanfang Database and VIP Database, from January 1990 to November 2017. Data were extracted and each merged data was analyzed using RevMan 5.3 software. The postoperative complications between transverse rectus abdominis musculocutaneous-flap (TRAM) and deep inferior epigastric perforatorflap (DIEP), TRAM and latissimus dorsiflap (LDF), LDF and LDF+ prosthesis, LDF+ prosthesis and simple prosthesis implantation were compared.Results:Twenty-nine papers met inclusion criteria of our study. The Meta-analysis results showed that the risk of local flap necrosis, seroma, infection, fat liquefaction, abdominal wall hernia and abdominal bulging in TRAM group were higher than those in DIEP group, and the differences were significant. There was no significant difference in total flap necrosis, wound dehiscence, venous congestion between the two groups; the risk of total flap necrosis, wound dehiscence and infection in TRAM group were higher than those in LDF group, and the differences were significant. The risk of seroma in TRAM group was lower than that in LDF group, and the differences were significant. There was no significant difference in fat liquefaction between the two groups; there was no significant difference in the postoperative complications between LDF group and LDF+ prosthesis group; the risk of seroma in LDF+ prosthetic group was higher than that in prosthetic group, and the differences was significant. The risk of prosthetic capsular contracture and prosthesis displacement in LDF+ prosthetic group were lower than those in prosthetic group, and the differences were significant. There was no significant difference in prosthesis exposure and infection between the two groups.Conclusions:DIEP has most of the advantages of TRAM and fewer complications. It plays an important role in breast reconstruction in the future. We should make a choice of breast reconstruction methods according to the patient＇s conditions as far as possible in clinical practice.

Objective To investigate the condition of nutrition in child with cerebral palsy (CP) and the effect of nutritional intervention. Methods 49 CP children and other 60 health children (controls) were measured their bodies, hemoglobin, serum trace elements, and bone mineral density (with ultrasonic), and the feeding behavior was also investigated. Results The incidence of malnutrition was 48.97%, in which 26.53% for low weight. The levels of serum iron and zinc were poor in the CP children, and the incidence of iron deficiency anemia was 34.67% in the CP children, different from the controls (P<0.05), while the incidence of low bone mineral density was 30.61%, not significantly different from the controls (P>0.05). Feeding problems were found in 44.9% of CP children. About 50% of malnutrition was corrected, especially the body weight after 4 months of Intervention, with anemia corrected in 88.2%, and bone mineral density recovered in 50%. Conclusion It is a problem for many CP children with malnutrition and nutritional disorders, and need nutrition intervention as the content of the rehabilitation.
