Journal of Regional Anatomy and Operative Surgery 2015;(4):379-381
Objective To evaluate the importance of the prenatal diagnosis to fetus with mild ventriculomegaly ( MVM) in pregnancy outcome and prognosis. Methods The ultrosonographic results of 51 pregnant women who were admitted to our hospital were collected in this study. In each case,a thorough evaluation of fetal anatomy was performed,karyotyping or MRI was done if needed,and follow-up was done un-til afterbirth. Results In 51 cases of lateral ventriculomegaly fetal:ultrasonography indicated there were 26 fetuses with mild ventriculomega-ly. The incidence of MVM complicated with other abnormities was 46. 0%,and that complicated with chromosome disorder was 11. 5%. Con-clusion Ultrasonography plays an important role in the detection of MVM. Chromosome analysis should be carried out for elder pregnant women when their fetuses are diagnosed as MVM and other complicating abnormities.

Objective To analyze the current status of the drug resistance of enterococci and monitor the prevalence of drug-resistant strains of enterococci in hospital infection. Methods 318 strains of enterococci separated from infectious samples in nine general hospitals in Hubei were assayed and tested with regard to drug sensitivity and the software of WHONET4 was used to analyze the data. Results The separation ratio of ARE, HLARE, VRE and ARE complicated with HLARE was respectively 16.98% , 37.76% , 0 and 5.66% . Conclusion The drug resistance of enterococci shows the tendency of increasing and consequent hospital infection shows the tendency of scattered prevalence. Laboratories of clinical microorganisms ought to closely watch the detection and spread of VRE.

BACKGROUND: Long term taking cyclosporin A(CsA)can inhibit osteoblastic differentiation and induce osteoporosis.Equol,which has greater binding affinity to estrogen receptors,can stimulate the proliferation and osteoblastic differentiation.OBJECTIVE: To investigate whether equol may protect against the proliferation and osteoblastic differentiation inhibited by CsA in mouse bone marrow mesenchymal stem cells(BMSCs)cultures and analyze signal pathway of protection.METHODS: Primary mouse BMSCs were cultured by using attachment method and assigned to five groups,which respectively treated with equol or/and CsA in the presence or absence of ICI182780,an estrogen receptor antagonist,and Nω-nitro-L-arginine methyl ester.Under an inverted microscope,morphological changes and mineralization ability of BMSCs were observed.The cell proliferation was measured by[3H]-thymidine incorporation.The osteoblastic differentiation and mineralization of extracellular matrix in BMSCs was assessed by measuring alkaline phosphatase activity and calcium deposition,respectively.Nitric oxide production in the conditioned media and cyclic guanosine monophosphata(cGMP)content in BMSCs were determined by using commercial nitric oxide and cGMP kit,respectively.RESULTS AND CONCLUSION: Equol reversed the decreased[3H]thymidine incorporation(P < 0.05),alkaline phosphatase activity(P < 0.05)and calcium deposition(P < 0.01)of CsA,which was accompanied with the changes of nitric oxide production(P < 0.01)and cGMP content(P < 0.01).The group by co-treatment with equol and CsA possessed higher cells growth density and small mineralized nodes than CsA group on day 12 under an inverted microscope.Moreover,the equol-reversed effect was abolished by ICI182780 and Nω-nitro-L-arginine methyl ester.These indicated that equol can reverse the inhibition of CsA on the proliferation and osteoblastic differentiation of mouse BMSCs through estrogen receptor/nitric oxide/cGMP signal pathway.

Objective To evaluate left atrial (LA) function by real-time three-dimensional echocardiography (RT-3D) and speckle tracking imaging (STI) after circumferential ablation of pulmonay vein ostia for atrial fibrillation guided by carto mapping system. Methods Thirty patients who had ablation procedure for paroxysmal atrial fibillation were accepted echocardiography to estimate the LA function at pre-operation,3 days and 3 months of post-operation. The LA maximal, minimal and pre-systolic volume (LAVmax, LAVmin and LAVp), LA passive ejection fraction (LAPEF), LA active ejection fraction (LAAEF) were measured by RT-3DE respectively. The strain rate curve was acquired in each LA segment (anterior, posterior, lateral, inferior and septal) by STI. Systolic strain rate (SRs), early diastolic strain (SRe) and late diastolic strain rate(SRa) of each left atrial segments were measured. Results Comparing with preoperative,3 days post-ablation SRs,SRe and SRa decreased significantly in each wall of LA. After 3 months,SRa and SRe in anterior, inferior and septal were significantly improved, however, SRs showed no significant difference. LAVmax and LAVpre were significantly decreased. LAPEF and LAAEF were significantly improved. Conclusions The patients with circumferential pulmonary vein ablation were in a deterioration after three days. The pump function and conduit functions of left atrial were increased after 3 months.

Objective To investigate the effects of BKCa channel on electrophysiology excitatory regulation in MVN neuron following hypoxia and to reveal its molecular mechanism.Methods C57BL/6 mices were performed MVNs hypoxia mice model,and randomly allowed to normal oxgen group and hypoxia group.The hypoxia group, according to the application of NS1 6 1 9 ,was further divided into the no NS1 6 1 9 pretreatment group and NS1 6 1 9 pre-treatment group.Using the patch clamp experiment technology,we recorded the effects of the MVN abnormal neu-ronal firing and the change of the BKCa currents.Using immunohistochemical technique,the changes of BKCa in the hypoxic MVNs detected were.Results Acute hypoxia increased neuronal activities.NS1619 pretreatment de-creased hypoxia-induced firing rate,and increased and postponed the maximum increase by hypoxia(P<0.05),al-so alleviated 10-min-hypoxia-induced depolarization(P<0.05).Perfusion with hypoxic significantly reduced the BKCa positive neurons(P<0.05).Conclusion These findings suggest that acute hypoxia increases neuronal activi-ties.The decreased MVN BKCa channels contribute to hypoxia-induced abnormal neuronal activities.

Objective To investigate the value of advanced virtual monoenergetic technique(mono-plus) of dual-energy CT (DECT) in improving imaging quality of the lliofemoral arteries.Methods Forty consecutive patients underwent DECT scan.Mono-plus images (40 keV),optimal monoenergy images and mixed energy images were obtained by using Siemens Syngo.via VB10A workstation.CT values,signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and subjective image quality were calculated in the abdominal aorta,iliac artery,external iliac artery,femoral artery,profound femoral artery, lateral circumflex femoral artery,transversal branch of lateral circumflex femoral artery,medial circumflex femoral artery and profound branch of medial circumflex femoral artery and compared among the three groups.Results Compared with the optimal monoenergy and mixed energy groups,CT value and CNR of the 9 arteries were significantly higher in the mono-plus group (P<0.003).SNR of the transversal branch of lateral circumflex femoral artery and the profound branch of medial circumflex femoral artery showed no significant difference (P>0.05) among the threegroups,whereas SNR of the arties bigger than the 6th grade branch were significantly lower in the mono-plus group (P<0.05).The subjective image quality in the mono-plus group was significant better than the other two groups(P<0.001).Conclusion 40 keV mono-plus technique in DECT can improve the display of lliofemoral arteries especially the small and distal branches.

Objective: Fungal keratitis is one of the most common diseases leading to blindness.It has a high incidence in China,and its early diagnosis and treatment are of vital importance.We aimed to investigate the value of laser confocal corneal microscopy in the clinical diagnosis of fungal keratitis.Methods: We conducted laser confocal corneal microscopy on 37 patients suspected of fungal keratitis,and compared the results with those obtained from the corneal tissue smears and fungal cultivation.Results: The fungus-infected corneas histologically exhibited defected epithelial cells,damaged subepithelial nerves and disordered stroma with reduced transparence.The hyphae showed bright,disordered,interlaced thread-or short rod-like structures.The positive rates of smear examination,fungus cultivation and laser confocal corneal microscopy were 48.65,62.16 and 78.39% for the 37 eyes,75.00,87.50 and100% for the 16 untreated eyes,and 28.57,42.85 and 61.90% for the other 21 pretreated eyes.Conclusion: Confocal laser corneal microscopy,rapid,effective and noninvasive,can be used as an important new alternative in the diagnosis of fungal keratitis
