Objective To study the clinical factors of sclerema neonatorum complicated with pneumorrhagia and propose therapy and control measures in order to.improve clinical treatment.Methods27 cases of sclerema neonatorum complicated with pneumorrhagia treated in Chaozhou Central Hospital from January 2005 to December 2007 were investigated retrospectively.Results In all 96 cases of sclerema neonatorum,27 Were complicated with pneumorrhagia.mortality of which was 67%.9 cases of pneumorrhagia without mechanical ventilation died totally.Early tracheal intubation discovered 9 cases of pneumorrhagia,mortality was 56%.5 cases died within the 6 oronasal emissing blood,taking up 83%in mortality.There were significant differences between them(P＜0.05).Conclusion The incidence of pneumorrhagia in sclerema neonatorum was closely related to fetal month,age,scleredema degrees,acidosis,birth weight ect.The more severe scleredema,the lower birth weight and the fewer fetal month were,the higher incidence rate was.

This study was aimed to establish and evaluate obese polycystic ovary syndrome (PCOS) rat model. Rats were randomly divided into the blank control group, high-fat model group, insulin (INS) combined human chorionic gonadotropin (HCG) model group, and INS combined HCG plus high fat emulsion model group. The obese PCOS rat model was induced by subcutaneous injection of INS and HCG on the nape, respectively. The intragastric administration of high fat emulsion was also used in the PCOS rat model establishment. The estrous cycle of rat was monitored. The detection was also made the weight increasing rate of rats, luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), testosterone (T), high-density lipoprotein (HDL), low density lipoprotein (LDL), triglyceride (TG), cholesterol (TC), fasting plasma glucose (FPG), fasting insulin (FINS), 2 h blood glucose and 2 h INS. Calculation was made on the HOMA index, related viscera index and bilateral ovaries HE staining. The results showed that when INS combined HCG improved method (INS combined HCG plus high fat emulsion model group) rats were sacrificed, the body weight, weight increasing rate, ovary viscera index, T, LH, and HOMA index were significantly higher than that of the blank control group, high-fat model group and INS combined HCG model group (P < 0.05,P < 0.01); HDL was significantly decreased (P < 0.05,P < 0.01). FPG, FINS, and 2 h INS of the INS combined HCG improved method group were significantly higher than that of the high-fat model group (P <0.01). It was concluded that INS combined HCG improved method was one of the ideal animal model establishment methods in the pathogenesis study of PCOS.

Aim To investigate the role of COX-2 in BMP9 induced osteogenic differentiation,and the pos-sible mechanism underlying this function of COX-2. Methods We introduced real-time PCR, Western blot, and immunocytochemical staing to detect the effect of BMP9 on COX-2 expression.We employed chemiluminescence technique to assay ALP activities, RT-PCR to detect the expression of Smad6 and Smad7 , and Western blot to measure the expression of Runx2, Dlx-5,total Smad1/5/8,and phosphorylated Smad1/5/8.Finally,BMPR-Smad luciferase reporter assay was applied to measure the activation of BMPs/Smads signaling.Results BMP9 could induce the expression of COX-2 in C3H10T1/2 cells.Either inhibiting enzy-matic activity of COX-2 or knockdown of the expression of COX-2 reduced the BMP9 induced ALP activities in C3H10T1/2 cells,and COX-2 knockdown also inhibited the ectopic bone formation induced by BMP9 in C3H10T1/2 cells.Moreover,COX-2 knockdown inhibi-ted BMPR-Smad reporter activities and the phosphoryl-ation of Smad1/5/8,so did the expression of Smad6 and Smad7 .Conclusion COX-2 may play an impor-tant role in BMP9 induced osteogenic differentiation in MSCs by regulating the BMPs/Smads signaling trans-duction.

Aim To investigate the anti-proliferation effect of resveratrol (Res)on human colon cancer cells and dissect the possible mechanism underlaying this effect.Methods We introduced crystal violet staining and Western blot to analyse the anti-proliferation effect of Res on HCT1 1 6 cells.Then,we used flow cytome-try and Western blot assay to detect the Res induced apoptosis in HCT1 1 6 cells.Next,we employed the well established TCF4 /LEF luciferase reporter to meas-ure the effect of Res on Wnt/β-catenin signaling trans-duction.Finally,we took Western blot and PCR assay to analyse the effect of Res on the expression of β-cate-nin in HCT1 1 6 cells.Results Crystal violet staining and Western blot analysis showed that Res could inhib-it the proliferation of HCT1 1 6 cells in a concentration-and time dependent fashion.What’s more,Res could promote apoptosis in HCT1 1 6 cells.The transcriptional activities of TCF4 /LEF reporter were reduced by Res in a concentration-dependent fashion (P <0.05 when the concentration of Res was 20 μmol·L -1 ,and P <0.01 when the concentration of Res was 40 μmol·L -1 or 80 μmol·L -1 ).Res could decrease not only the protein level of β-catenin in HCT1 1 6 cells,but also the mRNA expression of β-catenin.Conclusion Res can inhibit the proliferation of HCT1 1 6 cells,which may be mediated at least by down-regulating the ex-pression of β-catenin to inhibit the Wnt/β-catenin sig-naling transduction.

Objective To study the relationship between the semen quality and age in infertile men in Qingyuan.Methods 727 cases of infertile men from Reproductive Medicine Center outpatient were enrolled and divided into 5 groups:≤ 25,> 25 - 30,>30-35,>35-40,>40 age groups.The semen characteristics were carried out by calculator assistance sperm analysis(CASA) technique and Diff-Quick staining method.Results The sperm density of >30 -35 age group was the highest,but there was no significantly difference from other groups(P >0.05).Semen analysis showed that the rates of PR,PR+NP and survival sperm were on downward trends with the increase of age,but not statistically significant(P >0.05).38.19% of >25 -30 age group reached WHO′s semen parameters standard,which was the highest proportion among 5 groups.And the proportion in >40 age group was the lowest,which counted for 27.42%.Conclusion The semen quality shows a down trend with the increase of age,however,the infertility could occur in the reproductive men at any stage.

Pulmonary embolism (PE) refers to the endogenous or exogenous emboli blocking pulmonary trunk or branches, causing clinical and pathophysiological syndrome of pulmonary circulation disorder, the incidence rate is high. Sometimes PE patients were lack of specific symptoms and signs, or without any symptoms, which often result in misdiagnosis, un-timely diagnosis, and the delay of treatment. A PE case with syncope, vomiting and shock, which was proved to be pulmonary artery trunk and branch wide embolism later, was presented so as to improve the understanding of the disease.
