Objective To evaluate the relationship between thyroid autoimmunity and the risk of preterm birth. Methods Literature search was done among PubMed, Embase, Wanfang Medical Database, China Academic Journal Network Publishing Database and China Biology Medicine disc from Jan. 1st 1980 to July 31st, 2015. (1) Literature were extracted according to inclusion and exclusion standards, and the quality of the extracted literature were evaluated by Newcastle-Ottawa Scale (NOS). (2) Meta-analysis was performed by RevMan 5 software formulated by using the Cochrane library databases. Various heterogeneity of the research was inspected firstly. According to the results of the inspection a certain effect model was selected (including fixed effects model, the random effects model) to be utilized in merger analysis. In this study pregnant women with both thyroid peroxidase antibodies (TPO-Ab) and thyroglobulin (TG-Ab) positive were defined as thyroid antibody positive pregnant women. Pregnant women with only TPO-Ab positive were defined as TPO-Ab positive pregnant women. Then the relationship of antibody positive and the risk of a pre-term birth was analyzed respectively. Results (1) Ten cohort studies were enrolled, of which NOS scale score were 7 or higher. All the studies are of medium quality and above. A total of 1 322 cases of preterm birth occurred among 19 910 pregnant women. (2) Positive thyroid autoantibodies did not increase the risk of preterm birth in euthyroid pregnant women (OR=1.41, 95%CI:0.83-2.40, P=0.200) or in pregnant women with hypothyroidism (OR=0.68, 95%CI: 0.32-1.44, P=0.310). Positive TPO-Ab in euthyroid pregnant women increase the risk of preterm birth significantly (OR=2.08, 95%CI:1.09-3.97, P=0.030), but positive TPO-Ab in pregnant women with hypothyroidism did not increase the risk of preterm birth significantly (OR=1.21, 95%CI:0.65-2.24, P=0.550). Conclusion Positive TPO-Ab is an independent risk factor of preterm birth in euthyroid pregnant women.

Objective Analyse the influencing factors of early enteral nutrition support in patients of severe acute pancreatitis( SAP). Methods From April 2006 to August 2008, a total of 57 patients with SAP were analyzed in two aspects:the APACHE II scores, Ranson scores, Balthazar CT scores, and some frequent complications (shock, MODS, ACS, severe sepsis, paralytic ileus, etc.) were compared in two groups of A(≤5 d) and B( >5 d) according to the initial time of enteral nutrition:Hie initial timing of entend nutrition,the above scores and complications were also compared in two groups of nasojejunal feedingtube and jejunostomy feeding tube. Results The APACHE H scores, Ranson scores, Balthazar CT scores and the incidence of shock, MODS and ACS in group A were significant higher than those in group B; The APACHE II scores, Ranson scores and Balthazar CT scores in group of nasojejunal feeding tube were significant lower than those in group of jejunostomy feeding tube, and the initial time of enteral nutritionin nasojejunal feeding tube was significantly earlier. Conclusions Early enteral nutrition support in SAP is influenced by multiple factors, especially of pathogenetic severity, severe complications and feeding pathways.Homeostasis and intestines functions recover are the sign of enteral nutrition initiation, and to carry out enteral nutrition in ≤5 d after admission is feasible.The APACHE II scores may be helpful to guide the time of EN start.

The cyanuric chloride linkers have been used for cyclizing polypeptide, but not used for α-conotoxin, the peptides with rich disulfide bonds and more amino acid residues. In this study, cyclic peptides c[A10L]PnIA-1-4 were synthesized efficiently by lysine assisted cyanuric chloride linkers with 28.92%-52.00% yields. The activity evaluation showed that the IC₅₀ values of c[A10L]PnIA-1 against α7 and α3β2 nAChR subtypes were 5 and 7 times higher than [A10L]PnIA respectively, and the subtype selectivity was maintained. The results of circular dichroism show that this cyclization method had no significant effect on its secondary structure. Compared with the commonly used head-to-tail cyclization in conotoxin cyclization, this method has the advantages of rapid reaction and high yield, which is expected to be further applied to the cyclization study of various α-conotoxins.

Objective To evaluate the application of time to positivity (TTP)in differential diagnosis of intracranial infection caused by coagulase-negative Staphylococcus (CNS).Methods One hundred and twenty-four adult patients with positive CNS isolated from cerebrospinal fluid (CSF)including 70 cases with intracranial infection and 54 cases of CSF contamination,who were admitted in Xiangya Hospital of Central South University during January to December 201 5,were retrospectively analyzed.The difference of TTP between two groups was compared,receiver operating characteristic (ROC)curve was analyzed and the area under the ROC curve (AUC)was calculated.The application of TTP in differential diagnosis of CNS infection was evaluated.SPSS 1 8.0 software was used to analyze the data.Results TTP in intracranial infection group was shorter than that in CSF contamination group [(23.5 ±7.5 )h vs. (37.6 ±1 0.5)h,t =-8.71 7,P =0.000].The AUC of TTP was 0.854.Taking the cut-off value of 27.94 h,the sensitivity,specificity,positive and negative predictive values in differentiation of two groups were 72.7%,91 .4%,90.0% and 72.2%,respectively.There were statistically differences in TTP of Staphylococcus epidermidis,Staphylococcus haemolyticus and Staphylococcus capitis between two groups (Z =-4.496,-2.322 and -2.399,respectively,P <0.05 or <0.01 ).Conclusion TTP can be used to discriminate early intracranial infection and CSF contamination caused by CNS,and also can identify intracranial infection caused by different categories of CNS.

Objective To report the surgical methods and results of pure laparoscopic radical cystectomy with orthotopic U-shape ileal neobladder.Methods From August 2010 to April 2014,19 patients with locally advanced bladder cancer (cT2-3 N0-2 M0) underwent pure laparoscopic radical cystectomy and Endo-GIA assisted orthotopic U-shape ileal neobladder reconstruction.Perioperative and follow-up data were collected.Results The surgeries were successful in all 19 cases with the operating time ranging from 261 to 380 min,blood loss of 100 to 350 ml.Postoperative hospital stay was 21±4 (15-26) days,postoperative intestinal function recovery time at 1.9±0.4 (1.5-2.3) days.Surgical margins were all negative.Lymph node positive rate was 32％ (6/19).Complications were including 1 case of lymphatic leakage; 3 cases of new bladder and urethra anastomotic fistula.There were 17 cases of urinary incontinence,all these cases were improved after 3 months,but there were still 8 cases of night-time incontinence.Three cases had unilateral ureteral reflux,ureter mild hydrocephalus,1 of the cases had recurrent infections within 1 month after surgery.After the anti-inflammatory and catheterization treatment,the symptoms were improved.Two cases had unilateral ureteral anastomotic stricture,one underwent percutaneous nephrostomy and cystoscope-assisted double J tube placement,another underwent laparoscopic ureteral neobladder reimplantation.One case had bilateral ureteral stenosis due to recurrent infections,and underwent bilateral laparoscopic ureteral-new bladder reimplantation.Patients were followed up for 8-42 months,no recurrence or distant metastasis was found.Conclusion Pure laparoscopic radical cystectomy with endo-GIA assisted orthotopic U-shape ileal neobladder can reduce surgical trauma and help patient's postoperative recovery.

"Wise men could recognize similarities, but the fool only recognizes differences" in Su-wen, which expounded clinical thinking methods of Chinese medicine (CM). "To recognize similarities and differences simultaneously" is of important clinical significance in understanding the laws of diseases. CM pays much attention to recognize similarities, while modern medicine emphasizes the differences observed. In order to develop integrative medicine (IM), similarities recognition and differences identification must be combined together to innovate new thinking methods of IM.
