RESUMEN
BACKGROUND:Most of the formulas for the clinical treatment of premature ovarian insufficiency have evolved from the basic formula of Liuwei Dihuang Pills,and have achieved good therapeutic efficacy.Currently,most of the experimental studies on Liuwei Dihuang Pills focus on morphological observations and physiological and biochemical detection of in vivo animal models,while fewer studies on molecular mechanisms have been reported. OBJECTIVE:To explore the molecular mechanism of Liuwei Dihuang Pills in the treatment of premature ovarian insufficiency based on the receptor gamma coactivator-1 alpha/mitochondrial transcription factor A/reactive oxygen species pathway. METHODS:Premature ovarian insufficiency model was established in mice by intraperitoneal injection of cyclophosphamide 120 mg/kg combined with busulfan 12 mg/kg,and then Liuwei Dihuang Pill suspension was used to intervene in premature ovarian insufficiency mice.After 12 weeks of intervention,the levels of follicle-stimulating hormone,luteinizing hormone,estradiol,anti-Mullerian hormone,8-hydroxydeoxyguanosine,total antioxidant capacity and reactive oxygen species in serum of mice were detected by ELISA method.The morphological changes in mouse ovaries were observed by hematoxylin-eosin staining.The ultrastructure of mouse follicular granulosa cells and the apoptosis of granulosa cell mitochondria were observed by transmission electron microscopy.The expression levels of receptor gamma coactivator-1 alpha and mitochondrial transcription factor A in mouse ovarian granulosa cells were detected by immunohistochemistry. RESULTS AND CONCLUSION:Compared with the model group,serum levels of follicle-stimulating hormone,luteinizing hormone,reactive oxygen species,and 8-hydroxydeoxyguanosine were decreased in the experimental group(P＜0.05),and the levels of estradiol,anti-Mullerian hormone,and total antioxidant capacity were increased(P＜0.05).Hematoxylin-eosin staining showed that in the model group,there were more atretic follicles and corpus luteum forms,some secondary follicles,and interstitial fibrosis and hyperplasia;in the experimental group,a large number of atretic follicles,few corpus luteum forms,primordial follicles were observed at the edges but there were few secondary follicles and no mature follicles.Transmission electron microscopy showed that the organelles in ovarian granulosa cells of mice in the experimental groups were relatively intact.Immunohistochemical results showed that compared with the model group,the expression level of receptor gamma coactivator-1 alpha in the ovarian tissue of mice increased slightly in the experimental group at the 4th week,and there was no significant change at the 8th and 12th weeks.The expression level of mitochondrial transcription factor A in the ovarian tissues of mice in the experimental group was transiently increased at the 4th week,and then slightly decreased,which were all significantly different from those of the model group.To conclude,Liuwei Dihuang Pills inhibit ovarian granulosa cell apoptosis in mice with premature ovarian insufficiency to a certain extent through the receptor gamma coactivator-1 alpha/mitochondrial transcription factor A/reactive oxygen species signaling pathway,thereby improving the endocrine function of the ovary,enhancing the antioxidant capacity,and attenuating the degree of oxidative stress damage.
RESUMEN
【Objective】 To investigate the independent risk factors of urinary tract infection (UTI) in recipients under-going renal transplantation of donation after brain death (DBD), so as to provide a theoretical basis for the prevention and control of postoperative UTI. 【Methods】 A retrospective study was conducted for recipients who received renal transplantation of DBD in our hospital during Jan.2021 and Dec.2021. The recipients were divided into the infection group (n=26) and non-infection group (n=74) according to the incidence of UTI 3 months after operation. The risk factors of UTI were identified with univariate and multivariate analyses. 【Results】 The incidence of UTI was 26%. Univariate analysis showed that gender, postoperative urinary fistula, time of indwelling catheter and time of indwelling double J tube were the influencing factors of UTI (P<0.05). Forward stepwise regression analysis showed time of indwelling double J tube (OR=1.086,95%CI:1.003-1.177,P=0.042) and time of indwelling catheter(OR=4.687,95%CI:2.064-10.645, P<0.010) were the independent risk factors of UTI (P<0.05). 【Conclusion】 The time of indwelling catheter and time of indwelling double J tube are the independent factors of UTI after renal transplantation of DBD.
RESUMEN
Objective To explore the correlation between childhood trauma and plasma adiponectin levels in patients with depression.Methods A total of 121 patients with depression and 39 healthy controls(control group)were enrolled.Childhood trauma questionnaire(CTQ-SF)was used to assess the experience of childhood abuse and neglect,and the patients with depression were divided into trauma group(n=53)and non-trauma group(n=68)according to the CTQ-SF score.The 17-item Hamilton depression scale-17(HAMD17)and the Hamilton anxiety scale(HAMA)were used to evaluate the severity of depression and anxiety symptoms,respectively.Plasma adiponectin levels of subjects were measured by enzyme-linked immunosorbent assay.Results The plasma adiponectin level of trauma group[3.82(2.44,4.92)μg/mL]was significantly lower than that of non-trauma group[4.64(2.98,6.43)μg/mL,P=0.01]and the control group[6.29(4.54,7.51)μg/mL,P＜0.01].The plasma adiponectin level of non-trauma group was lower than that of the control group(P＜0.01).Correlation analysis showed that plasma adiponectin level in patients with depression was negatively correlated with childhood trauma(r=-0.34,P＜0.01).Multivariate linear regression analysis showed that plasma adiponectin level was negatively correlated with childhood trauma scores in patients with depression(β=-0.05,P＜0.01).Conclusions Patients with depression who have experienced childhood trauma have lower plasma levels of adiponectin,and childhood trauma may be associated with decreased plasma adiponectin levels in patients with depression.

Objective:To explore the relationship between marital status and mild cognitive impairment in older adults.Methods:This study is a cluster random sampling.From January to December 2020, a questionnaire survey was conducted among older adults aged 60 years and over in four cities of Hebei Province.Finally, 2690 older adults with mild cognitive impairment and normal cognitive function were enrolled.The older adults were divided into 2 groups according to their marital status: married and living with their spouses(group E1), divorced or living alone(group E2). The mini-mental state examination(MMSE)scores of older adults in the two groups were compared.Moreover, the cognitive differences of older adults between the two groups and the interaction of marital status, social activities and life events on cognitive outcomes were analyzed.Results:The married older adults with partners had better cognitive preservation( P<0.01). The more life events were more likely to cause cognitive impairment( P<0.01), and the interaction of marital status, social activities and life events had a significant impact on cognition( P<0.01). Older men who were married and lived with spouse had better cognition than older women who were married and lived with spouse( P<0.05 in Model 3). The cognition of widowed elderly women was better than those of widowed elderly men( P<0.1 in Model 1; P<0.1 in Model 2). Among elderly men, the cognition of those married and living with spouse was better than that those of widowed( P<0.01 in models 1 and 2, P<0.1 in model 3). Among elderly women, those married and living with spouse had better cognitive outcomes than those widowed( P<0.01 in Model 1, P<0.01 in Model 2). Conclusions:Marital companionship is a protective factor for the cognition of older adults, and there are gender differences in the impact of marital status on cognition in late life.
RESUMEN
Light therapy, a non-intrusive approach, is now considered as a promising new treatment method for a variety of mood disorders such as depression, bipolar disorder, postpartum depression and so on. However, the neural mechanism of light therapy to regulate emotions is still unclear, and the clinical application of light therapy and its side effects are still controversial. Light therapy regulates mood may be related to the changes of neural circuit mediated by intrinsically photosensitive retinal ganglion cells(ipRGCs), clock gene expression, circadian rhythm and sleep structure. In this paper, the treatment of mood disorders by light has been discussed, and a variety of neural circuits and molecular biological mechanisms of light therapy are introduced, meanwhile, the current situation and side effects of light therapy have been analyzed, in order to provide evidence for the application and promotion of light therapy in the treatment of mood disorders.
RESUMEN
The onset of depression is related to many factors such as biological, psychological and social environment, and more and more studies have shown that early life adversity is a risk factor for depression. Patients with depression who have early life adversity have different clinical characteristics, such as greater cognitive impairment and higher risk of suicide, which may be related to changes in cognitive patterns. In addition, early life adversity can cause endocrine, immune and nervous system specific changes in depressed patients. This article reviews the relationship and mechanism between various types of early life adverse and depression, explores the onset of depression and provides theory evidence for early intervention.

Objective:To investigate the effect of salvianolic acid on depressive behavior in depression model rats induced by chronic mild stress (CMS) and its mechanism.Methods:Fifty healthy male clean grade Sprague-Dawley(SD) rats were divided into five groups according to a random number table with 10 in each group: control group (nCMS+ Nal group), CMS+ normal saline group (CMS+ Nal group), CMS+ fluoxetine group (CMS+ Flu group), CMS+ salvia acid group (CMS+ Sal group), CMS+ fluoxetine+ Salvia acid group (CMS+ Flu+ Sal group). Except the control group, the rats in the other four groups were all received CMS modeling for 21 days. Twenty-one days after CMS modeling, rats were intraperitoneally injected with 0.9% normal saline (10 mg·kg -1·d -1), fluoxetine (20 mg·kg -1·d -1), salvia acid(40 mg·kg -1·d -1), fluoxetine(20 mg·kg -1·d -1)+ salvia acid(40 mg·kg -1·d -1)for 21 days. During the administration period, rats in the other four groups continued to receive CMS intervention for 21 days. Forced swimming test and sucrose preference test were conducted at baseline (day 0), after modeling (day 21) and after intervention (day 42) so as to evaluate depression like behavior. Then the rats were sacrificed and the hippocampus and prefrontal cortex were taken. The mRNA levels of Toll like receptor 4 (TLR4) and myeloid differentiation primary response 88 (MyD88) were detected by RT-qPCR. The cytokines including interleukin-1β(IL-1β), interleukin-2(IL-2), interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) were detected by Luminex technique.SPSS 21.0 was used for statistical analysis.Repeated measurement ANOVA was used for behavioral data analysis, one-way ANOVA was used for molecular index data analysis, and Spearman was used for correlation analysis. Results:The results of repeated measurement ANOVA showed that the interaction effects between group and time of body mass, sucrose preference, forced swimming immobility time were significant at baseline, after modeling and after intervention ( F=18.238, 6.921, 7.591, all P<0.05). After modeling, compared with nCMS+ Nal group, the rats in CMS+ Flu group, CMS+ Sal group, CMS+ Flu+ Sal group and CMS+ Nal group had lower body weight, lower sucrose preference rate and longer forced swimming immobility time (all P<0.05). After intervention, compared with CMS+ Nal group(body weight (350.15±41.65)g, sucrose preference(52.95±11.13)%, static time(91.40±15.22)s), the body weight((378.21±30.78)g, (385.12±43.19)g, (391.41±31.21)g, (402.33±18.67)g, all P<0.05) and sucrose preference((69.30±15.56)%, (68.12±10.99)%, (71.18±9.51)%, (75.47±11.55)%, all P<0.05) of CMS+ Flu group, CMS+ Sal group, CMS+ Flu+ Sal group and nCMS+ Nal group were all increased, while the forced swimming immobility time ((68.81±21.74)s, (66.10±25.51)s, (63.53±22.32)s, (71.21±21.41)s, all P<0.05) were shorter (all P<0.05). After intervention, among the body weight, sucrose preference and the immobility time of CMS+ Flu group、CMS+ Sal group and CMS+ Flu+ Sal group, there were no differences between each two groups(all P>0.05). After intervention, the levels of TLR4 mRNA and MyD88 mRNA in prefrontal cortex and hippocampus of CMS+ Flu group, CMS+ Sal group, CMS+ Flu+ Sal group and nCMS+ Nal group were all lower than those in CMS+ Nal group (all P<0.05). In prefrontal cortex, the levels of TLR4 mRNA (0.715±0.358) and MyD88 mRNA (0.739±0.233) in CMS+ Flu+ Sal group were lower than those in CMS+ Sal group (1.943±0.606, 1.815±0.897) (both P<0.05). The level of TLR4 mRNA in prefrontal cortex and hippocampus of rats were positively correlated with the level of MyD88 mRNA and TNF-α level and forced swimming immobility time and negatively correlated with sucrose preference rate (prefrontal cortex r=0.915, 0.041, 0.027, -0.178, all P<0.05; hippocampus r=0.810, 0.070, 0.011, -0.153, all P<0.05). Conclusion:The antidepressant effect of salvianolic acid is presumedly achieved by inhibiting the immunoinflammatory response mediated by the TLR4/Myd88 signaling pathway in CMS rats.

Objective:To explore the association between polymorphism of Histone Deacetylase 2 (HDAC2) gene and alcohol use disorder (AUD) in male people of Han nationality for seeking suitable single nucleotide loci(SNP), and provide reference for early diagnosis and intervention of alcohol use disorder(AUD).Methods:A total of 194 male AUD patients of Han nationality (case group) and 310 normal men of Han nationality (control group) were selected for the study. The genomic DNA of peripheral blood of the subjects in the two groups was extracted, and 13 SNP loci of HDAC2 gene were obtained from HapMap database. The subjects in the two groups were genotyped by Agena MassARRAY SNP genotyping method.SPSS 25.0 was used to statistically analyze the differences of genotype frequency and allele frequency between the two groups, and Haploview 4.2 software was used for linkage disequilibrium and haploid analysis. The multiple test correction was carried out by the replacement test with 50 000 replacement times.Results:The genotype frequency of the 3 SNP loci(rs9481408, rs6568819, rs9488289) of HDAC2 gene were statistically significant different between the case group and the control group (all P<0.05). Further analysis found that the three loci were significantly correlated with AUD in the recessive genetic model between case group and control group(T/T vs C/C-C/T: OR=1.78, 95% CI: 1.05-3.03, P=0.033; T/T vs C/C-C/T: OR=1.79, 95% CI: 1.05-3.03, P=0.032; G/G vs C/C-C/G: OR=1.85, 95% CI: 1.09-3.13, P=0.022). Seven SNP haplotypes were constructed and the association odds ratio of GATCTGCAATAA between the case group and control group was 2.44, and the difference was statistically significant ( P<0.05). Conclusion:The SNP loci rs9481408, rs6568819, rs9488289 in the HDAC2 gene and haplotype GATCTGCCAATAA are associate with AUD in male people of Han nationality. These results indicated that the HDAC2 gene is one of the susceptibility genes of AUD.

RESUMEN
Objective To investigate the effect of Tangshan earthquake stress on the executive and memory func?tion in adults. Methods The objects were recruited from Tangshan Kailuan Mining Group. The exposed group included 251 subjects whose mothers exposed to the Tangshan earthquake during pregnancy in 1976. The control group included 341 subjects whose mothers was pregnant the year after the Tangshan earthquake. According to mother's pregnancy time relative to the earthquake exposed group was divided into 3 subgroups:the late pregnancy of earthquake exposed group, the second trimester of earthquake exposed group and the early pregnancy of earthquake exposed group. Wisconsin Card Sorting Test (WCST) was used to evaluate executive function, Brief Visuospatial Memory Test-Revised (BVMT-R) was used to evaluate memory function. Results The index of WCST were not different between two groups (P>0.05). Com?pared with control group, BVMT-R total scores were lower in earthquake exposed group [(25.54 ± 7.45) vs. (27.28 ± 7.10), P<0.01]. In the earthquake exposed group, pregnancy and sex had interaction effect on the nonpreservative errors (nRpe) of WCST (P<0.05). In the late pregnancy earthquake exposed group, male had higher nRpe than female (P<0.01). Preg?nancy time had main effect on offsprings' BVMT-R scores (P<0.05). The BVMT-R total scores were lower in late trimes?ter pregnancy and in second trimester pregnancy than in the early pregnancy (P<0.05). Conclusion The Tangshan earth?quake has potential effect on the memory function of the offsprings. The second trimester (4-to 6-month) and the third trimester (7-to 9-month) may be the sensitive pregnancy window of the stress during the pregnancy. The male offspring from late pregnancy of exposed earthquake have poorer executive function than female.
RESUMEN
Objective:To explore the differences of the early response time between transcranial magnetic stimulation (rTMS ) and modified electroconvulsive therapy (MECT )in patients with first-episode depression.Methods:Totally 65 first-episode patients aged 18 -45 year were enrolled in the study.The diagnoses were made according tothe Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-Ⅳ)criteria for depression.The patients randomly received rTMS(n =33)or MECT (n =32).All patients received co-therapy of escitalopram (10 -20 mg /day).Stimulation (20 Hz)was performed five times a week for four weeks and,a total of 20 consecutive working days over the left dorsolateral prefrontal cortex(DLPFC).MECT group received MECT treatment 3 times a week for 3 weeks,a total of eight times.The Hamilton Depression Rating Scale-24 items (HAMD)was used to assess the severity of clinical symptoms and reduction rates.Results:Compared with the pa-tients in MECT group,the patients in rTMS group showed a less reduction rates [(25.0.±3.1),(34.4 ±7.7), (52.2 ±7.8),(69.1 ±8.3),vs(28.2 ±5.4),(38.8 ±5.1 ),(57.7 ±6.8),(75.4 ±8.6),Ps <0.05]in the first four weeks and the suicidal behavior scores reduced less in rTMS group in the first two weeks (P <0.05).Conclu-sion:It suggests that both rTMS at 20 Hz and MECT combined with escitalopram could improve the first-episode depression within a week.While the efficacy of rTMS combined with escitaloprm slightly less than MECT com-bined with essitaloprm in rapid response and reducing the suicide risk of acut period.

Objective To study the moderate hypothermia with iced saline given intravenously with ice cap and ice sheet used in patients with severe stroke or craniocerebral trauma in order to clarify its clinical therapeutic effect and recovery of neurologic function for providing reliable clinical data.Methods A total of 84 patients suffered severe stroke (cerebral hemorrhage or cerebral infarction) or traumatic brain injury with GCS (Glascow Coma Scale) ＜8 admitted within 24 hours after onset were enrolled for study.The exclusion criteria were functional decompemsation of heart,liver,kidney and lung as cardiovascular complications of hypertension,hematological and other diseases,and craniocerebral trauma with multiple injuries of thorax,abdomen and extremities.Patients were divided into observation group and control group (n =42 in each group).The patients of two groups were managed to maintain respiratory tract patent,prevention of infection,dehydration,reduction of intracranial pressure and treated with Cytidine Diphosphate Choline,piracetam,ganglioside sodium and other conventional therapy.In control group,patients treated with ice cap and ice sheet,whereas in observation group,patients were treated with iced saline injected intravenously in addition to ice cap and sheet.At admission,the GCS score of patients was assessed and 6 months later,GCS score and Glascow Outcome Scale,(GOS) score of patients were determined,and 12 months after the treatment,quality of life score were evaluated by KPS.Results The time from onset of stroke or from trauma accident occurred to initiation of hypothermia treatment and time from initiation of hypothermia therapy to the target temperature reached in observation group were (8 ±4) hours and (3± 1 )hours respectively,and in control group,they were ( 16± 5) hours and (6 ± 2) hours,and there were significant differences between two groups ( P ＜ 0.05 ).The mean GCS score of patients at 6 months in the observation group and in the control group were (7.01 ± 1.12) and (4.02 ± 1.11 ) respectively (P ＜0.05 ) ; whereas the GOS score at 6 mouths of patients was categorized into good outcome,disabled outcome and poor outcome,and the good outcome in the observation group was significantly better than that in the control group (P ＜ 0.05 ),and no statistically significant difference in disabled outcome was found between two groups (P ＞ 0.05),and the poor outcome of GOS score was significantly lower in observation group than that in control group ( P ＜0.05 ).Twelve months after the treatment,the long-term quality of patients'life assessed by KPS score in observation group was significantly better than that in control group ( P ＜ 0.05).Conclusions The moderate hypothermia therapy by using iced saline administered intravenously combined with ice cap and ice sheet for severe stroke and head trauma patients conferred better therapeutic effects than the treatment with ice cap and ice sheet.
RESUMEN
ObjectiveTo evaluate the advantages of color doppler ultrasonography guidence in mini-invasive percutaneous nephrostolithotripsy(mPCNL) for pediatric patients.MethodsFrom May 2006 to August 2011,a total of 165 pediatric cases with upper urinary stone,who were treated by mPCNL with F12-F16 access route,were respectively reviewed.All procedures were under the guidance of color doppler ultrasonography,and the pneumatic lithotripsy and/or EMS ultrasound lithotripsy were used to disintegrate the stones.ResultsIn one-stage mPCNL,The average length of the stones was ( 15.82 ±6.31 ) mm,all 165 cases were treated,during which percutaneous renal access was successfully established under color doppler ultrasound guidance and stones were fragmentated.The mean duration of renal access establishment was (11.7 ± 5.3 ) min.The one-stage stone free rate was 95.2％(157/165) with the operation time of (42.6 ± 20.1 ) min.The postoperative hemoglobin aud hematocrit decline were observed in 69.7 ％ ( 115/165 ) of the cases with the value of 2.67 g/L and 2.21％ respectively when compared with their preoperative counterpart. Infection rate related to operation was 23.03％ ( 38/165 ),which was demostrated by durative or iterative fever more than 48 hours.No perioperative bleeding was recorded,and no transfusion was required.No ease experienced perirenal organ injury.Conclusions Using color doppler ultrasound guidance during m-PCNL resulted in safe and effective therapeutic method for upper urinary stone,and can be considered as measures of choice for guidence of mPCNL in pediatric patients.
RESUMEN
Objective To evaluate the targeted antimicrobial prophylaxis in men undergoing trans-rectal ultrasound guided prostate biopsy based on rectal swab culture results.Methods From July 2008 to April 2012 we studied differences in infectious complications in men who received targeted vs standard empirical ciprofloxacin prophylaxis before transrectal ultrasound guided prostate biopsy.All 344 patients were divided into 3 groups according to their hospital records,inculding group A:without antimicrobial prophylaxis(105 eases) ;group B:antimicrobial prophylaxis with fluoroquinolone(117 cases) ;group C:targeted prophylaxis used rectal swab cultures results(122eases).All cases received enema with diluted iodophors before biopsy.We identified men with infectious complications within 7 days after transrectal ultrasound guided prostate biopsy using the electronic medical record,following 3 conditions.Results In group A of 105 case,17 cases of fever were recorded,including prostatic abscess of 3 cases and septicemia of 1 case.Three cases of fever were occurred in group B,including 1 case of bacteremia and 1 case of prostatitis.No infectious complications were recorded in group C.Conclusions Targeted antimicrobial prophylaxis was associated with a notable decrease in the incidence of infections complications after transrectal ultrasound guided prostate biopsy,although fiuoroquinolone can provide good protective effets.
