ABSTRACT

TORCH, which is considered as a series of pathogens, including the Toxoplasma gondii, Rubella virus, Cytomegalovirus or Herpes simplex virus, often infects the pregnant women to induce the the fetus or newborn infection by transplacental infection or exposure to contaminated genital tract secretions at delivery. Increasing evidence have been confirmed that the infection of TORCH may cause the miscarriage, premature birth, malformed fetus, stillbirth, intrauterine growth retardation, neonatal multiple organ dysfunction and other adverse pregnancy outcomes. For most TORCH-infections cases may lacking the effective treatments during pregnancy, and it is important to achieve the effacing monitoring of TORCH infections before and during pregnancy. The laboratory testing of TORCH has the great significance. However, the consensus opinions still need to improve the the standardization of TORCH testing process and the correct interpretation. Based on the characteristics of the TORCH detection method, this article gives a consensus opinion on the standardized detection and clinical application of TORCH from the laboratory perspective according to the characteristics and types of infection of different pathogens.

ABSTRACT

Objective To investigate the correlation factors for hot flashes in climacteric women so as to improve their quality of life. Methods A questionnaire was distributed among 792 climacteric women. The questionnaire items included general information, characteristics of menstruation, reproduction history, information of hot flashes, lifestyle and sexual life. Weight, height, blood pressure, waist and hip circumferences were measured. Logistic regression analysis was made to find out the correlation factors for hot flashes. Results Univariate logistic regression analysis showed that age, education, income, present characteristics of menstruation, dietary habit, soy products intake, physical exercise, satisfaction of sexual life, body mass index (BMI) and systolic blood pressure were significantly associated with hot flashes. Multivariate logistic regression analysis revealed that irregular menstruation or menopause, frequent exercise and higher systolic blood pressure were risk factors for hot flashes in climacteric women. However, higher education, soy products intake and satisfaction of sexual life were protection factors. Conclusion Guiding climacteric women to take moderate physical exercise, knowing more about climacterium, consuming more soy products and controlling diastolic blood pressure are likely to decrease the incidence of hot flashes.

ABSTRACT

GAP-43,netrin-1,collapsin-1,and neuropilin-1 have been regarded to play crucial roles in the formation of patterned neural connections.The cerebellum consists of five distinct concentric layers:white matter,internal granule layer (IGL),Purkinje cell layer (PCL),molecular layer (ML),and external granule layer (EGL) in young rodents.Cells in EGL are generated after birth.In contrast Purkinje neurons are born before birth,which receive main innervations of climbing fibers fi'om the inferior olivary nucleus and parallel fibers from the internal granule cells.These innervations are mostly established in the first three postnatal weeks,accompanying the sprouting and maturation of Purkinje cells.The potential roles of GAP-43,netrin-1,collapsin-1 and neuropilin-1 in the postnatal development of cerebellum remain unclear.To get insights into the above issue,the expression of GAP-43,netrin-1,collapsin-1,and neuropilin-1 mRNAs and proteins were examined in the cerebellum of mice at postnatal days (P) 5,P10,P20 and adulthood.The results showed that these four molecules were expressed in different temporal and spatial patterns in the postnatal cerebellum of mice,which was in match with axonal synaptogenesis,elongation and synapse formation during postnatal development and adulthood.By using double immunohistocbemistry,it was found that the Purkinje cells stained for GAP-43 were also positive for either netrin-1 or collapsin-1 at P10,and cells stained for collapsin-1 were also positive for netrin-1 or neuropilin-1.It was suggested that the four molecules are involved in the postnatal development of cerebellum.

ABSTRACT

Objective To study the effect of the levels of serum gonadal hormone and plasma calcitonin gene-related peptide(CGRP) on the hot flushes symptom of perimenopausal women. Methods 65 perimenopausal women (35 with hot flushes and 30 without hot flushes) and 25 healthy fertile women were enrolled. The subjects were analyzed for serum estradiol (E2), follicle-stimulating hormone (FSH) ,luteinizing hormone (LH) and plasma calcitonin gene-related peptide (CGRP). Results. ① There were no significant differences of the E2 levels between the perimenopausal women with and without hot flushes (P>0.05). The levels of FSH and LH were significantly higher in the women with hot flushes than women without hot flushes and fertile women(P<0.05),② The levels of plasma CGRP were significantly higher in the women with hot flushes than women without hot flushes (P<0.05), and significantly lower than fertile women,③The levels of plasma CGRP were significantly higher in severe hot flu-shes group than that in the mild hot flushes group and moderate hot flushes group(P<0.05), the severity of hot flu-shes was positively related to the level of plasma CGRP(rs=0.823, P<0.01), but there was no relationship be-tween serum E2 and the severity of hot flushes (P>0.05). Conclusion The occurrence of perimenopansal hot flu-shes might be closely related to the decline and fluctuation of serum E2,increase of FSH and LH and the concentra-tion variety of plasma CGRP.

ABSTRACT

OBJECTIVE:To study the effect and thepossible mechanism of low molecular weight heparin(LMWH)on immunocytes' adhesion to fibroblast-like synovocytes(FLS)isolated from patients with rheumatoid arthritis(RA)and to study LMWH'S possible anti-inflammatory effect on RA.METHODS:LMWH's interference on the adhesion of peripheral blood monouclear cells(PBMC)isolated from healthy volunteers to FLS of RA patients was determined by quantitative counting using flow cytometry.The expression of CYR61 in the in vitro cultured FLS of RA patients was detected using real-time PCR technology.RESULTS:When FLS culture system was added with PBMC,PBMC were obviously found to adhere to FLS,but the number of adhered PBMC decreased after LMWH treatment,which manifested as increase of deciduous PBMC,increased more with the increase of LMWH dose.There was a high expression of CYR61 in synovium tissue in RA patients.CONCLUSION:LMWH inhibited the adheresion of PBMC to FLS from RA patients in a dose-dependent manner,which might be attributed to its competitive combination with heparin sulfate sites on CYR61.

ABSTRACT

The efferent and afferent projections of the hyperstriatum ventrale, pars caudal nucleus (HVc) in carduelis spinus were investigated using anterograde and retrograde HRP tracing techniques. After injecting HRP into the HVc, anterogradely labelled fibers and terminals were observed in the robust nucleus of the archistriatum (RA), tractus archistriatum dorsalis (DA) and the area X of lobus parolfactorius. The dense retrogradely labelled cell bodies were found in medial magnocellular nucleus of the anterior neostriatum (mMAN), nucleus interfacialis (NIf) of midneostriatum, telencephalic auditory area--field L of the neostriatum, and locus ceruleus (LoC) of pons. All these projections were ipsilateral. Based on the present and previous studies, the authors got the following understanding: 1. The HVc projects to the high vocal control centre--RA. This proved that the HVc is also a high vocal control nucleus. 2. The HVc receives afferent projections from the telencephalic auditory area--field L. It indicates that there are direct connection between the two high centres of audition and vocal control nuclei in telencephalon. 3. This study demonstrated that the HVc receives afferent projection from the LoC for the first time. According to the fact, we presume that HVc may be involved in the neural regulations of vegetative function and emotional reactions. 4. The HVc also receives afferent projections from the mMAN and NIf of neostriatum, and from the Uva of the thalamus. On the other hand the HVc projects to area X. Since the mMAN, NIf, Uva and area X are vocal learning and memory centres, therefore the HVc may be also involve in vocal learning and memory functions.
