【Abstract】 Background Serum folic acid level is associated with the incidence of depression to some extent.Folic acid,as an additive treatment for depression,can significantly improve the clinical depressive symptoms,but the mechanism is unknown.Objective To investigate the effects of sertraline plus an additive treatment with folic acid on serum levels of brain-derived neurotrophic factor(BDNF) and homocysteine (Hcy) in depressive patients.Methods According to the inclusion criteria of this study,we enrolled 100 patients with depressive disorder from Department of Psychiatry,Wuhan Second Mental Hospital from January 2017 to January 2018,and assigned 50 of them to the control group and other 50 to the intervention group,respectively,by use of a random number table.Both groups received routine sertraline therapy,the intervention group additionally received folic acid.All the cases were treated for 8 weeks.Intragroup and intergroup comparisons were made at baseline and at the end of the treatment in terms of serum levels of folic acid,BDNF,Hcy,neural function related factors〔astrocyte-derived protein S100B,myelin basic protein (MBP),neuron specific enolase (NSE),and insulin growth factor-1
(IGF-1)〕,Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Rating Scale (HAMA) scores and clinical response.Adverse reactions were assessed by the Treatment Emergent Symptoms Scale (TESS).Results After treatment,the intervention group showed significantly increased serum folic acid level compared to the baseline(P<0.05),and demonstrated much higher average serum folic acid and BDNF levels but significantly lower average Hcy level compared with the control group (P<0.05).After treatment,serum levels of S100B and NSE decreased significantly in the two groups compared to the baseline(P<0.05);intervention group showed much lower average serum levels of S100B and NSE(P<0.05),but similar average MBP and IGF-1 levels (P>0.05) compared with the control group.HAMD and HAMA scores declined significantly in both groups after treatment(P<0.05).But the intervention group had much lower post-treatment HAMD and HAMA scores than the control group(P<0.05).The overall response rate of the intervention group was much higher than that of the control group〔96.0%(48/50)vs 82.0%(41/50)〕 (χ2=5.005,P<0.05).The intervention group and the control group showed no significant difference in the incidence of adverse reactions〔16.0%(8/50)vs 14.0%(7/50)〕 (χ2=0.078,P>0.05).Conclusion Sertraline plus an additive treatment with folic acid can effectively increase serum folic acid and BDNF levels in depressive patients,and reduce the serum levels of Hcy,S100B and NSE.

【Abstract】 Background Presbycusis is a kind of disease in which hearing threshold increases slowly with age.Spiral modiolar artery(SMA) plays an important role in maintaining cochlear blood supply and hearing production.Connexin 43(Cx43) is widely expressed in the vascular wall and has an important effect on the vasomotor function,but the relationship between its expression in the cochlear spiral artery and presbycusis is still unclear.Objective The senile deafness guinea pigs induced by D-galactose(D-gal) were studied to explore the relationship between Cx43 on SMA and presbycusis.Methods In May 2018,36 specific pathogen free(SPF) guinea pigs aged three months without ear diseases were randomly divided into the Control group,NS group and D-gal group with 12 guinea pigs in each group.On the basis of normal feeding,guinea pigs in the D-gal group and NS group were subcutaneously injected with D-gal 500 mg·kg-1·d-1 and 0.9% sodium chloride solution(the same volume as the D-gal group) respectively in the neck and back,while guinea pigs in the Control group were raised normally without any treatment.All guinea pigs in three groups were raised for six weeks in total.Three neonatal guinea pigs born in the Control group were taken and sacrificed to isolate SMA.The primary SMA vascular smooth muscle cells(VSMCs) were cultured by adherence method.After identification,the 3rd generation of SMA VSMCs was used to prepare cell senescence model.SMA VSMCs in control group were normally cultured for 48 h.SMA VSMCs in aged group were normally cultured with 30 g/L D-gal for 48 h.SMA VSMCs in the AAP10 group were pretreated with 100 nmol/L AAP10 and then cultured with 30 g/L D-gal for 48h.Morris water maze test was used to detect the escape latency of guinea pigs on day 1,2,3,4 and 5 and the number of times of crossing the platform on day 6 in the Control group,NS group and D-gal group.The threshold values of auditory brainstem response(ABR),superoxide dismutase(SOD) activity and malondialdehyde(MDA) level of liver tissue,brain tissue and serum,and Cx43 mRNA on SMA and protein were compared among the Control group,NS group and D-gal group.SOD activity,MDA level and Cx43 expression in VSMCs were compared among the control group,aged group and AAP10 group.Results There was an interaction between group and time in the escape latency of guinea pigs(Finteraction=6.99,Pinteraction<0.05) and the main effects of group and time were significant(Fintergroup=53.43,Ftime=38.15;Pintergroup<0.05,Ptime<0.05).The escape latency in D-gal group was longer than that in Control group and NS group on day 3,4,and 5(P<0.05).The number of times of crossing the platform in D-gal group was less than that in Control group and NS group on day 6(P<0.05).ABR threshold and MDA level of liver tissue,brain tissue and serum in D-gal group was higher and SOD activity of liver tissue,brain tissue and serum was lower than that in Control group and NS group(P<0.01).SOD activity in VSMCs in aged group was lower and MDA level was higher than that in control group and AAP10 group(P<0.01).SOD activity in VSMCs in AAP10 group was lower and MDA level was higher than that in control group(P<0.01).Cx43 mRNA on SMA and protein expression in D-gal group was lower than that in Control group and NS group(P<0.01).The expression of Cx43 in VSMCs in aged group was lower than that in control group and AAP10 group(P<0.05) and the expression of Cx43 in VSMCs in AAP10 group was lower than that in control group(P<0.05).Conclusion The change of Cx43 expression on SMA in guinea pigs induced by D-gal may be related to presbycusis,which lays a foundation for future clinical follow-up research.

【Abstract】 Background In vitro fertilization-embryo transfer(IVF-ET) is one of the main technologies to treat infertility.The treatment of infertility has rapidly improved since IVF-ET appeared.The clinical pregnancy rate of IVF-ET at home and abroad has reached 30%-40% at present.However,many patients still fail after transferring high-quality embryos.It is generally believed that the reason lies in the uterine environment.Endometrial polyps(EPs) are an important cause of uterine environment deterioration.Low endometrial receptivity(ER) after transhysteroscopic resection of polyps(TCRP) will prolong the treatment cycle and reduce the success rate of IVF-ET.How to improve the endometrial receptivity of these patients and make them get pregnant is an urgent problem to be solved now.Objective To observe the clinical effect of warming acupuncture combined with acupoint injection on low ER of patients undergoing frozen-thawed embryo transfer(FET) after TCRP,and to explore the mechanism of ER improvement by warming acupuncture combined with acupoint injection.Methods Twenty-seven female patients with low ER after TCRP due to EPs during IVF-ET pregnancy cycle were enrolled from Traditional Chinese Medicine Department,Foshan Maternal and Child Health Hospital from January 2015 to July 2018.They were divided into observation group(13 cases) and control group(14 cases) by random table method.Both groups were given the Progynova after menstruation.In the control group,patients could received FET after ER recovery.In the observation group,patients were treated with warming acupuncture combined with acupoint injection(human placenta tissue fluid),and they could receive FET after ER recovery.The rate of endometrial type a,rate of endometrial and subendometrial blood flow type A,number of high-quality embryos transferred,time spent on FET and clinical pregnancy rate were compared.Results There were no significant differences in type a rate of endometrium,type A rate of endometrial and subendometrial blood flow between the observation group and the control group after treatment(P>0.05).There were no significant differences in the number of high-quality embryos transferred and the clinical pregnancy rate between the two groups(P>0.05).The time spent on FET in observation group was shorter than that in control group(P<0.05).Conclusion Warming acupuncture combined with acupoint injection can shorten time spent on FET of patients with low ER after TCRP.The mechanism may enhance the uterine blood flow perfusion,give ER sufficient energy,improve repairing ability after endometrial injury,thus optimizing the uterine environment,reversing the low ER status,and creating good conditions for embryo implantation.

【Abstract】 Background Ashi acupoint is a commonly used acupoint for the treatment of skeletal muscle injury by acupuncture and moxibustion.However,the timing of intervention for acute skeletal muscle injury has not been reported.Objective To investigate the effects of electro-acupuncture(EA) at Ashi acupoint at different time points on high-frequency ultrasound-based gastrocnemius(GM) contusion injury score,and serum CK in a rat model of GM contusion Injury.Methods In September 2017,60 male Sprague-Dawley (SD) rats were randomly divided into blank group (n=6),model group (n=18),24 h EA group (n=18) and 72 h EA group(n=18).Except the blank group,other three groups were treated with the method developed by our research group(put forward in a previous study of ours) for establishing the acute contusion model of GM muscle,and ultrasound imaging technology was used to evaluate the modeling.As rats can not talk like humans,we selected the midpoint of the injured GM muscle abdomen,identified with ultrasound guidance,as the needling site.Except the blank group,6 rats in each group were captured at the 3rd,5th and 7th days(each time different ones were captured) after modeling to receive the following interventions:rats in 24 h EA group,72 h EA group were given the first EA treatment at 24,72 hours after GM muscle injury,respectively.Rats in model group were grasped and fixed by the same way simultaneously,but received no EA treatment.The blank group received no intervention.High-frequency ultrasound examination of injury severity and ultrasound-based GM injury scoring of rats in each group were performed at the 3rd,5th and 7th days after modeling,respectively,then they were sacrificed in batch to test serum CK value.Results There were no significant differences in ultrasound-based GM injury score evaluated immediately,on the 3rd,5th,and 7th days after modeling among the model group,24 h EA group,and 72 h EA group (P>0.05).On the 3rd day after modeling,the difference of ultrasound-based GM contusion injury score between the interventional time point and immediately after modeling in the 24 h EA group was higher than model group,72 h EA group (P<0.05).The serum CK levels on the 3rd,5th and 7th days after modeling in the model group were all higher than those in the blank group (P<0.05).The serum CK levels in 24 h EA group on the 5th and 7th days after modeling were both higher than the blank group(P<0.05).In 72 h EA group,the serum CK level was lower than that of the model group on the 3rd day after modeling,and higher than that of blank group on the 5th and 7th days after modeling (P<0.05).Conclusion EA at the Ashi acupoint improved the GM contusion injury in rats.And applying EA treatment at 24 hours after injury may promote the repair earlier.
