Objective To explore the clinical correlation of the variation of plasma homocysteine (HCY), melatonin (MLT) and ulceative colitis (UC). Methods The clinical data of 112 UC patients was collected, and 110 normal healthy persons as control. The level of plasma HCY and MLT was detected by high pressure liquid chromatography-fluorescence detection (HPLC-FD) method. The level of plasma folate ( FA) and vitamin B12 was detected by enzyme-linked immunosorbent assay (ELISA) method. The correlation of these four indexes and UC was analyzed. Results The serum level of HCY in UC patients was significantly higher than that in normal healthy persons [(11. 27± 7.26) μmol/L vs (8. 19±4. 81) μmol/L, P = 0. 000]. The serum level of MLT in UC patients was significantly lower than that in normal healthy persons [(49. 06 + 31. 40) pg/ml vs (64. 28±41. 16) pg/ml,P=0. 008]. The serum level of FA in UC patients was significantly lower than that in normal healthy persons [(7. 64 + 1.95) nmol/L vs (9. 14 + 1.23) nmol/L, P = 0. 005]. The serum level of vitamin B12 in UC patients was significantly lower than that in normal healthy persons [(108. 64 ±32. 22) pmol/L vs (112. 64±33. 33) pmol/L, P = 0. 004]. There was no correlation between plasma HCY, MLT and UC disease activity degree, range, disease duration, erythrocyte sedimentation rate (ESR), or C reactive protein (CRP) in UC patients. There was no significant correlation between MLT and HCY in UC patients. Conclusions The serum level of HCY is higher in UC patients than that in normal control, and MLT is lower than that in normal control. However there is no significant correlation between them.

Objective:To study the kinetics of transdermal absorption of volatile oil from Angelica slinesis in fetal skin and investi-gate the mechanism of penetration enhancement in terms of morphology. Methods: Franz diffusion cells were used to investigate the transdermal characteristics in vitro. The content of ligustilide was determined by HPLC, and the cumulative permeation amount per unit area and rate constant of ligustilide were calculated. The effects of volatile oil from Angelica slinesis on skin ultrastructure was observed by a scanning electron microscope and a transmission electron microscope. Results:The kinetics of volatile oil at different concentra-tions was all in accordance with Higuchi equations. The ultrastucture changes of fetal skin under the scanning electron microscope were as follows:the wrinkles on skin surface increased, some areas of stratum corneum peeled off and turnovered like worn-out cotton pad-ding, the follicular orifice was enlarged, and the cuticles of the hair shaft dropped off and became thinner. The changes of fetal skin ul-trastucture under the transmission electron microscope were as follows:stratum corneum cells peeled off, the cell junction in basal lam-ina and stratum spinosum were broken, and the intercellular space was enlarged. Conclusion: The volatile oil from Angelica slinesis has good transdermal permeability. Its enhancement mechanism of transdermal drug absorption is closely related with the effects on skin ultrastructure, which can change the structure of stratum corneum to increase the cell gaps resulting in enhancing drug penetration.

Objective To explore the effect of the midwife-leading labor pain management model on the pregnancy outcomes and pain control satisfaction.Methods The randomized grouping and single blind trial design were performed.One hundred and ten pregnant women were recruited and randomized into the control group (n=55) and intervention group (n=55).The control group received the routine prenatal examination by the outpatientdepartment obstetric doctors and intrapartum nursing care during labor.On this basis the intervention group participated in the labor pain educational course in the midwife clinic,and received the repeated pain assessment and pain management intervention during labor.Results There was no statistical difference in the delivery mode between the two groups(P＞0.05).The cesarean section rate without indication in the intervention group was significantly lower than that in the control group,the difference was statistically significant(x2 =6.798,P＜0.05).The average each item score of the labor pain education and pain control satisfaction in the intervention group was significantly higher than that in the control group,the difference was statistically significant(P＜0.01).Conclusion The midwife-leading labor pain management model can reduce the cesarean section rate without indication,and improves the satisfaction of labor pain education and pain control in pregnant women and parturients.

Aim To investigate whether Hcy influenced the intestinal mucosal permeability by regulating MEK-ERK-MLCK pathway. Methods SD rats were divided into 4 groups:normal group, normal+Hcy group, TN-BS/ethanol group, TNBS/ethanol+Hcy group. Experi-mental colitis model with hyperhomocystinemia was es-tablished in rats with intracolonic administration of TN-BS and subcutaneous injection of Hcy. The colonic mucosal tissue was collected for histopathological exam-ination and activity of myeloperoxidase ( MPO ) . The protein expression of MLCK, p-MLCK, MEK, ERK and p-ERK in intestinal mucosal tissues was examined by Western blot method. The mRNA expression of ML-CK was examined by RT-qPCR method. Result Com-pared with the normal group and TNBS group, the DAI and HI scores and the MPO activity were increased in TNBS/ethanol+Hcy group ( P <0. 01 ) . Western blot and RT-qPCR showed that expression of MLCK, p-ML-CK, MEK, ERK and p-ERK increased in small intes-tine in TNBS/ethanol+Hcy group. Conclusion Hcy can increase intestinal permeability in TNBS-induced colitis rats by regulating the expression of MEK-ERK-MLCK signal pathway.

Objective To evaluate the role of nitric oxide in sevoflurane postconditioning-induced mitigation of autophagy and cell apoptosis during ischemia/reperfusion (I/R) in isolated rat hearts.Methods The hearts of male Sprague-Dawley rats,aged 2-3 months,weighing 250-300 g,were excised and retrogradely perfused in a Langendorff apparatus.One hundred and eight isolated rat hearts,which were successfully perfused in a Langendorff apparatus,were equally and randomly divided into 6 groups:control group (C group),sevoflurane group (S group),I/R group,sevoflurane postconditioning group (SSP group),sevoflurane postconditioning + L-NAME (non-selective nitric oxide synthase (NOS) inhibitor group (SSP + L group),and L-NAME group (L group).The hearts were perfused with K-H solution for 150 min in C group.The hearts were continuously perfused for 180 min and perfused with K-H solution containing 3％ sevoflurane for 15 min starting from 60 min of perfusion in S group.After being perfused with K-H solution for 30 min,the hearts were subjected to occlusion for 30 min followed by reperfusion for 120 min in the other groups except C and S groups.After onset of reperfusion,the hearts were perfused with K-H solution containing 3％ sevoflurane for 15 min in SSP group,the hearts were perfused with K-H solution containing 3％ sevoflurane and L-NAME 100 μmol/L for 15 and 60 min,respectively,in SSP + L group,and the hearts were perfused with K-H solution containing L-NAME 100μmol/L for 60 min in L group.Inn ediately before ischemia,and at 30,60,90 and 120 min of reperfusion,each parameter of cardiac function was recorded.At the end of reperfusion,myocardial specimens were obtained at the end of reperfusion for measurement of the infarct size,NOS activity,NO content,and expression of Bcl-2,Beclin 1 and caspase-3,for observation of formation of autophagosomes,and for examination of the pathological changes.Results Compared with C group,LVSP,+ dp/dtmax,-dp/dtmax,NOS activity and NO content were significantly decreased,and LVEDP was increased in I/R and SSP groups.Compared with I/R group,LVSP,+ dp/dtmax,-dp/dtmax,NOS activity and NO content were significantly increased,LVEDP was decreased,Bcl-2 expression was down-regulated,and the expression of Beclin 1 and caspase-3 was up-regulated in SSP group,and no significant changes were found in each index in SSP+ L and L groups.Compared with SSP group,LVSP,+ dp/dtmax,-dp/dtmax,NOS activity and NO content were significantly decreased,LVEDP was increased,Bcl-2 expression was down-regulated,and the expression of Beclin 1 and caspase-3 was up-regulated in SSP + L group.Conclusion The mechanism by which sevoflurane postconditioning reduces I/R injury may be related to promoted NO product and inhibited autophagy and cell apoptosis in isolated rat hearts.

Objective To investigate the spatiotemporal expression patterns and the relationship of α-sarcomeric actin(α-SCA) ,α-smooth muscle actin(α-SMA) and intermediate filament protein desmin with the maturation of the prenatal and the neonatal mouse hearts. Methods Serial sections of the embryo mouse and the neonatal mouse hearts were immunostained with antibodies against α-SCA, α-SMA and desmin. Results Ventricle and outflow tract of embryonic day(ED) 9 heart showed stronger expression of α-SCA and α-SMA, but desmin expression was lower. In the atrium, the expressions of α-SCA and α-SMA were restricted to the dorsal and ventral walls. In the sinus venosus, only a few weakly stained α-SCA positive cells were detected. No desmin expression was found in the atrium and sinus venosus. The expressions of α-SCA, α-SMA and desmin were increased to their highest level at ED 12. The higher expression of α-SCA remained to the postnatal stages. After ED 12, the expressions of α-SMA and desmin gradually decreased in different parts of the heart, but their expressions in the right ventricle persisted longer. After birth,desmin expression was mainly concentrated in the Z lines of I bands and intercalated disks. Conclusion The presence of spatiotemporal differences in the expression of α-SMA and desmin reveals regional differences in cardiomyocyte maturation in various parts of the embryonic mouse heart. The right ventricle shows a relatively slow pace of maturation. The α-SMA may contribute to a peristaltoid contraction pattern of the embryonic myocardium with a slow shortening speed, and a relatively higher level of desmin is required for the maturation of the sarcomere.
