Objective To investigate the value of C- reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-?) in early diagnosis of neonatal sepsis. Methods Sixty- five newborns were divided into experiment group and control group, experiment group was also divided into sure group and doubtful group by blood culture We assessed the level of serum CRP, IL-6 and TNF-? in 24 hours and after 24 hours of clinical diagnosis of sepsis in experiment group, and examined the blood culture before antibiotic treatment Serum CRP, IL-6 and TNF-? were also examined in 3 to 6 days old. Results 1 The levels of serum CRP, IL-6 and TNF-? in experiment group were significantly higher than that in control group 2. The sensitivity of IL-6 and TNF-? were higher than CRP in 24 hours in experiment group. 3. After 24 hours, the sensitivity of CRP was elevated,and there was no statistical difference compared with the IL-6. Conclusion IL-6 and TNF-? are the credible marker in the early diagnosis of neonatal sepsis, and are more sensitive than the CRP, the IL-6 is the first sensitive marker.

Objective To investigate an association between Toll-like receptor(TLR)4 Asp299Gly or CD14 C-260T polymorphisms and colorectal cancer in Chinese patients.Methods By a method of polymerase chain reaction-based restriction fragment length polymorphism(PCR-RFLP), TLR4 Asp299Gly and CD14 C-260T polymorphisms in unrelated 110 patients with colorectal cancer and 160 healthy controls in Chinese Han race population were genotyped.Results Significant differences of CD14 genotypes were found between healthy controls and the patients with colorectal cancer.The fre- quency of the CC genotype in healthy controls was extremely lower than that in the group of colorectal cancer(15.6% vs.31.8%,P=0.0027,OR=0.3968,95%CI:0.2209-0.7129)while the frequency of the CT genotype in healthy controls was significantly higher than that in the group of colorectal cancer (48.1% vs.30.9%,P=0.0056,OR=2.074,95%CI:1.246-3.452).No TLR4 Asp299Gly mutant genotype was detected in any patients and healthy controls in Chinese Han population.Conclusion The polymorphism of CD14 C-260T but not TLR4 Asp299Gly is associated with colorectal cancer in Chinese patients.

This study aimed to explore Semaphrin4D (Sema4D) expression and clinical significance in non-small cell lung cancer (NSCLC), and to define the roles and mechanisms of Sema4D in regulating the malignant behaviors of A549 cells by small interfering RNA (siRNA). Firstly, immunohistochemistry revealed that Sema4D was more frequently expressed in NSCLC than in lung benign lesion (P<0.05) and its overexprssion was associated with low differentiation (P<0.05), poor pTNM staging (P<0.05) and occurrence of lymph node (LN) metastasis (P<0.05). Endogenous Sema4D expression was suppressed by Sema4D siRNA in A549 cells overexpressing Sema4D. Protein levels of Sema4D, total Akt and p-Akt were examined by Western blotting. Cell proliferation, migration and invasion abilities were measured by MTT assay and Transwell assay respectively. Results showed that Sema4D siRNA significantly suppressed phosphorylation of AKT in A549 cells, but it did not alter total AKT expression. In addition, efficient down-regulation of SemaD significantly inhibit cell proliferation (P<0.05), migration (P<0.05) and invasion (P<0.05) in A549 cells. These findings suggest that Sema4D might serve as a reliable tool for early prediction of NSCLC poor prognosis. Sema4D could play an important role in promoting tumor proliferation, migration and metastasis in the NSCLC, by influencing the Akt protein phosphorylation. Inhibition of Sema4D may be a useful approach for the treatment of NSCLC.

Objective To systematically evaluate the effectiveness of delayed cord clamping (DCC) in term infants. Methods The data of the Cochrane library, PubMed, EMBASE, CNKI , VIP, Wanfang from 1 January 1970 to 30 April 2013 were searched. Randomized controlled trials (RCT) of DCC in term infants were included.RevMan 5.1.0 was used in the statis-tical analysis. Results Ten studies involving 1623 participants were included. Meta-analysis based on included studies showed that:compared with immediate cord clamping (ICC), DCC improved the hemoglobin levels at birth (MD=2.19, 95%CI:0.36, 4.02) and increased the incidence of polycythaemia (RR=2.87, 95%CI:1.24, 6.62). Compared with ICC, DCC showed no signi-ficant difference in the phototherapy for hyperbilirubinemia (RR=2.46, 95%CI: 0.93, 6.52), the hemoglobin levels within 6 months (MD=0.29, 95%CI:-0.17, 0.75), and the incidence of anemia (RR=0.71, 95%CI:0.45, 1.12). Conclusions DCC can improve the hemoglobin level in term infants after birth. However, the appropriate time of cord clamping has not been deter-mined. It is necessary to undertake further studies with higher quality and larger scale to evaluate the optimal time of cord clam-ping.

Objective To evaluate the effects of delayed cord clamping (DCC) on preterm infants with gestational age ＜32 weeks.Methods Literatures from January 1,1990 to April 30,2013 in Cochrane library,PubMed,EMBASE,China Academic Journal Network Publishing Database,Wanfang Medical Database and VIP Database were searched.Randomized controlled trials (RCT) of DCC in preterm infants with gestational age ＜32 weeks were screened and evaluated.DCC was defined as cord clamping in 30-90 s after delivery,and early cord clamping (ECC) (＜30 s) was as the control.Rev Man 5.1.0 was used for statistical analysis.Mean difference (MD) and 95％CI were used for continuous data while OR and 95％CI were for categorical data.Results Nine studies (11 articles) involving 373 infants were included.Compared with ECC,DCC improved hematocrit (MD=4.19,95％CI:2.97-5.40,Z=6.74,P＜0.000 01),blood volume (MD=11.70,95％CI:6.02-17.38,Z=4.04,P＜0.0001) and mean arterial pressure of preterm infants with gestational age ＜32 weeks (MD=3.11,95 ％CI:1.30-4.92,Z=3.37,P=0.0008),decreased the usage of volume expansion for hypotension (OR=0.32,95％CI:0.11-0.98,Z=2.05,P=0.04) and the incidence of necrotizing enterocolitis (OR=0.48,95％CI:0.25-0.92,Z=2.22,P=0.03).Meanwhile,DCC had no influence on the peak bilirubin concentration,the incidence of sepsis,patent ductus arteriosus,retinopathy and intracranial hemorrhage,also no influence on neonatal mortality on dcscharge,mental developmental index and psychomotor developmental index at seven-month old.Conclusions DCC might be a safe procedure to improve prognosis of preterm infants less than 32 weeks' gestational age.However,due to small sample size and lack of data on follow up,it is necessary to launch clinical trials with higher quality and larger scale to further evaluate the effect and safety of DCC.

Objective To investigate the antitumor therapeutic effect of combined therapy of magnetic induction heating by nano-magnetic particles, herpes simplex virus thymidine kinase gene(HSV-tk suicide gene) and internal radiation in mice bearing MCF-7 breast carcinoma. Methods The transfection reagents, plasmids heat shock protein-HSV-tk (pHSP-HSV-tk), ferroso-ferric oxide nano-magnetic fluid flow and 188Re-ganciclovir-bovine serum albumin-nanopaticles (GCV-BSA-NP) were prepared. The heating experiments in vivo were carried out using ferroso-ferric oxide nano-magnetic fluid flow. Sixty mice tumor models bearing MCF-7 breast carcinoma were established and randomly divided into six groups. Group A was the control group, B was gene transfection therapy group, C was hyperthermia group, D was gene transfection therapy combined with radionuclide brachytherapy group, E was gene therapy combined with hyperthermia group, and F was gene therapy, hyperthermia combined with radionuclide brachytherapy group. The tumor growth, tumor mass and histopathological changes were evaluated. The expression of HSV-tk in the groups of B, D, E and F was detected by RT-PCR. Poisson distribution and one-way analysis of variance (ANOVA) were used for statistical analysis by SPSS 10.0 software. Results In the animal heating experiments, the temperature of tumor increased up to 39.6 ℃, 43.2 ℃, and 48.1 ℃ quickly with different injected doses (2, 4 and 6 mg respectively) of nano-magnetic particles and maintained for 40 min. The temperature of tumor tissue reduced to 36.8 ℃, 37.5 ℃ and 37.8 ℃ in 10 min when alternating magnetic field (AMF) stopped. The tumor mass in Groups C ((452.50 ±30.29) mg), D ((240.98 ±35.32)mg), E((231.87 ±27.41) mg) and F ((141.55 ±23.78) mg) were much lower than that in Group A ((719.12±22.65) mg) (F=800.07, P＜0. 01), with the most significant treatment effect in Group F.The tumor mass in Group B((684.05 ±24.02) mg) was higher than that in Group D (t =32. 805, P ＜0. 05). Semi-quantitative RT-PCR analysis showed that the expression of HSV-tk in Groups B and D (0.33 ±0. 13 and 0. 46 ±0.12) was significantly different from that in Groups E and F (0.66 ±0.13 and 0.74 ±0. 11)(F = 21. 573, P ＜ 0.05). Conclusion Combined use of hyperthermia, gene therapy and radionuclide brachytherapy could effectively depress the growth of MCF-7 breast carcinoma, thus possessing treatment potential for this tumor.
