OBJECTIVETo study the effect of Compound Ezhu Powder (CEP) on serum levels of CA125 and CA19-9, and the expression of cyclin D protein in endometriosis patients, thus providing theoretical evidence for clinical application of CEP.

METHODSTotally 69 all endometriosis patients underwent surgical treatment at Department of Gynecology and Obstetrics, Tianjin Nankai Hospital from January 2011 to January 2013 were randomly assigned to group A (35 cases) and group B (34 cases). Meanwhile, 30 patients with uterine fibroids who prepared for surgical treatment during the same period were recruited as the control group. Patients in group A took EZP 3 months before surgery. No treatment was given to patients in group B and the control group. The serum CA125 level and the expression of cyclin D in the ectopic endometrium and the eutopic endometrium were detected in the 3 groups before surgery.

RESULTSThe expression of cyclin D was higher in group A and group B than in the control group (P < 0.05). The serum levels of CA125 and CA19-9 were significantly lower in group A than in group B (P < 0.05). The expression of cyclin D in the ectopic endometrium was lower in group A than in group B, but with no statistical difference (P > 0.05). The expression of cyclin D in the eutopic endometrium was significantly lower in group A than in group B with statistical difference (P < 0.05). Meanwhile, the serum CA125 level was positively correlated with the serum CA19-9 level (r = 0.45, P < 0.05).

CONCLUSIONSThe expression of cyclin D obviously increased in endometriosis patients, which was associated with the occurrence of endometriosis. CEP could lower serum levels of CA125 and CA19-9, and down-regulate the expression level of cyclin D, indicating its roles in inhibiting the cell cycle.

Objective:To Study the effect of static magnetic field on the proliferation and differentiation of osteoblasts.Methods:In vitro cultured rat calvarial osteoblasts were seeded into 96-well culture plate and exposed to the different magnetic intensity field for 24,48 and 72 h respectively.MTT assay was applied to study the cell proliferation. ALP was measured by a microplate reader.Results:When the magnetic exposure time extended to 48 h or 72 h, the corresponding MTT value of osteoblasts with magnetic treatment of 40 mT or 62 mT increased obviously(P0.05). ALP activity increased after 24 h exposure to static magnetic field, the effect of static magnetic field intensity of 62 mT and 83 mT showed the strongest promotion effect(P

Cofactor engineering, a vital part of metabolism engineering, changes the redox cofactor regeneration approach. Its main goal is to rebuild the components of metabolic products. The bioconversion of xylose for the production of ethanol is being studied intensively because ethanol is an alternative energy source and a potential liquid fuel. Saccharomyces cerevisiae has been traditionally used in producing ethanol from fermentable sugars but it cannot utilize xylose, only its isomer xylulose. Introduction of the xylose fermentation pathway from Pichia stipitis into S. cerevisiae enables xylose utilization in recombinant S. cerevisiae, but the ethanol yields of xylose fermentation with recombinant S. cerevisiae has been low and large amounts of the byproduct xylitol are produced. The major reason is that the catabolism of xylose with the fungal pathway leads an imbalance of redox cofactor. The process of the catabolism of xylose requires NADPH and NAD~+, both of which have to be regenerated in separated processes. More and more attention has therefore focused on the redox cofactor balance in S. cerevisia. The research progress of cofactor engineering to solve the imbalance of redox cofactor in xylose metabolism recombinant S. cerevisiae was introduced. This included expression of transhydrogenase, increasing the utilization of NADPH, and achieving the anaerobic reoxidation of NADH. Reversing the cofactor specificity of enzymes is another effective way.

Objective To explore the echocardiography characteristics of non-compaction of ventricular myocardium(NVM),and assess its value in the diagnosis of NVM.Methods Philips SONOS 5500 color Doppler ultrasound system with 2-4 MHz transducers was used in 9 patients with NVM.Results In all 9 patients,the presence of multiple trabeculations and multiple deep intertrabecular Space communicating with the ventricular cavity was demonstrated by color Doppler imaging.Both ventricles were involved in 1 patient,only the left ventricle in 7 patients,and right ventricle in 1 patient.Conclusions NVM has typical ultrasonic appearance on echocardiography.It Can find out the NVM manifestations even if patients do not have any symptoms.It is a reliable and convenient way for diagnosing NVM.

Objective To make molecular identification for 9 isolates of Taenia saginata from 4 provinces.Methods Genomic DNA was extracted from the segments of adult tapeworms collected from Taoyuan of Taiwan(TW1),Duyun of Guizhou(DY1,DY2),Congjiang of Guizhou(CJ1,CJ2,CJ3,CJ4),Dali of Yunnan(DL1) and Wushi of Xinjiang(XJ1) respectively.PCRs were carried out with 13 random primers.A phylogenetic tree of different geographical strains was constructed.Results 331 DNA fragments were amplified.The number of DNA fragments amplified by single primer was between 3 and 28.The average number of amplified DNA fragments by the 13 primers was 14.15.The average number of fragments from the 9 isolates of T.saginata was 14.08.Phylogenetic tree revealed that there were two branches in the tree,DY1,DY2,DL1 and TW1 occupied one branch,while CJ1,CJ2,CJ3,CJ4 and XJ1 occupied the other one.Conclusions By the RAPD analysis,the isolates DY1,DY2,DL1 and TW1 belong to Taenia saginata asiatica,and the isolates CJ1,CJ2,CJ3,CJ4 and XJ1 belong to T.saginata saginata.

Objective To explore the relationship of human cytomegalovirus(HCMV) infection and infantal epilepsy.Methods Fluorescence quantitative polymerase chain reaction was employed to detect the urine HCMV-DNA in 20 healthy children and 52 infants with epilepsy,and the changes in head CT scanning and brainstem auditory evoked potential were determined in HCMV positive and negative epilepsy infants.Results Positive HCMV-DNA was found in 31(59.62%)infants with epilepsy and 6(30%)healthy infants,there was significant difference between two groups(P

Nuclear factor-erythroid 2 related factor 2 (Nrf2) is an ubiquitous and important transcription factor. It regulates antioxidant response elements (AREs)-mediated expression of antioxidant enzyme and cytoprotective proteins. A large body of research showed that Nrf2-Keap1 (Kelch-like ECH-associated protein 1, Keap 1)-ARE signaling pathway is involved in the endogenous antioxidant defense mechanisms. Nrf2 increases the expression of a number of cytoprotective genes, protects cells and tissues from the injury of a variety of toxicants and carcinogens. As a result, Nrf2 enhances the expression of glutathione and antioxidants such as superoxide dismutase and glutathione S-transferase, and subsequently scavenging free radicals. Air pollution especially from PM2.5 particles, is associated with an increasing morbidity of inflammatory pulmonary diseases and their deterioration. More and more studies demonstrated that Nrf2 was a novel signaling molecule in the modulation of inflammatory responses in these inflammatory respiratory diseases, such as asthma, acute lung injury (ALI) and COPD. Therefore, Nrf2 targeting might be a therapeutic target, which will provide clinical benefit by reducing both oxidative stress and inflammation in asthma, acute lung injury (ALI) and COPD. This review focused on the relationship between Nrf2 and inflammatory respiratory diseases and oxidative stress.
