Chinese Journal of Postgraduates of Medicine 2008;31(34):19-21
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.

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.

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 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

Objective To investigate the best MR technique for detecting small epidermoids in the cerebellopontine angle.Methods 7 patients with pathologically-proved small epidermoids only located in the cerebellopontine angle were collected. The imaging techniques included:conventional T1WI and T2WI, fluid attenuated inversion recovery(FLAIR),diffusion weighted imaging(DWI) and balanced fast field echo(B-FFE) .The findings were retrospectively analyzed.Results 6 of 7 cases of epidermoid tumours localized at the cerebellopontine angle and exhibited the similar signal intensity as the cerebrospinal fluid(CSF) on T1WI and T2WI.The remaining case was slightly isointense on either T1WI or T2WI.On FLAIR images in 6 cases,3 cases showed slightly hyperintensity, 1 case showed doubtful heterogeneous signal intensity and 2 cases did not reveal any abnormal signal intensity.3 cases were hyperintense differenting from CSF on DW images. All of seven cases showed heterogeneous signal characteristics and were quite different from CFS on B-FFE.Meanwhile B-FFE also produced clearly the tissue contrast of trigeminus embedded in epidermoids of the cerebellopontine angle.Conclusion B-FFE is much more useful for the early diagnosis of epidermoids in the cerebellopontine angle and it also can provide precise preoperative information about the trigeminus encasement.

Objective · To explore the effects of brisk walking on blood pressure, body mass index (BMI), and autonomic nerve activity of male elderly with hypertension in community-based health centers in Shanghai. Methods · A total of 630 elderly men received brisk walking treatment (>10000 steps/d) voluntarily, who were selected from six community-based health centers in Pudong New Area of Shanghai. Among them, 210 people stick to training for 12 weeks. According to whether suffering from hypertension, the people were assigned to hypertension intervened group (intervention group, n=110) and normal intervened group (control group 1, n=100). Blood pressure, BMI, heart rate and autonomic nerve activity before and after the training were compared. Results · After 12 weeks of training, systolic blood pressure (SBP), diastolic blood pressure (DBP) and sympathetic nerve activity of intervention group were significantly lower than those before the training (P<0.05). SBP was also significantly lower than control group 2 (P<0.05). However, heart rate, BMI, parasympathetic nerve activity and baroreceptor reflex sensitivity did not change significantly after the training (P>0.05). Conclusion · Brisk walking treatment lasting for 12 weeks can decrease blood pressure and sympathetic nerve activity in elderly men with hypertension. It is worthy to be popularized in the community.
