Objective : To explore the mechanism of hippocampal corticotropin-releasing hormone ( CRH) receptor type 1 ( CRHR1 ) in chronic stress-induced learning and memory impairment in early aged mice． Methods: C57BL /6J mice aged 12 －14 months were divided into two groups according to gender，and then divided into wild type (WT) group and hippocampal CRHR1 conditional gene knockout (KN) group according to genotype．Mice in each group were randomly divided into control group and stress group，and the stress group was subjected to chronic unpredictable stress ( CUS ) for 30 days． Genotyping of mice was performed using polymerase chain reaction ( PCR) ，agarose gel electrophoresis and real-time fluorescence quantitative PCR (RT-qPCR) ．The new object rec- ognition experiment and Morris Water maze measured learning and memory ability．Golgi-Cox staining was used to observe damage to hippocampal neuronal dendrites． The protein expressions of target protein of rapamycin (mTOR) ，p-mTOR (Ser2448) ，ribosomal protein S6 kinase ( p70S6K) and p-p70S6K ( Thr389 / Thr412 ) were detected by Western blot．Serum levels of corticotropin releasing hormone ( CRH) were measured by ELISA. Results : Compared to mice without chronic stress，the cognitive coefficient of WT stress groups decreased after chron- ic stress，and the difference was statistically significant (P ＜0. 05) ，while there was no significant difference in cognitive coefficient of KN stress groups before and after chronic stress．Compared with the WT stress group，the escape latency of the WT control group was shortened (P＜0. 05) ，and the number of crossing the platform and tar- get quadrant increased (P ＜0. 01) ，and there was no significant difference in the KN groups above． Compared with the WT control group，the WT stress group had a significant reduction in the neuronal complexity in the hipp- ocampal CA1，CA3 and DG regions (P ＜0. 05) and significant reductions in the expression of p-mTOR and p- p70S6K in the hippocampus (P＜0. 05) ．There was no significant difference in the expression of p-mTOR between the KN stress group and the KN control group (P＞0. 05) ，except that the expression of p-mTOR in the hippocam- pus of the female group decreased (P＜0. 05) ．In addition，the serum level of CRH in the stress group was higher than that in the control group (P＜0. 01) ． Conclusion Hippocampal CRHR1 regulates learning and memory im- pairment and neuronal dendrite damage in early aged mice induced by chronic stress．The mechanism may be that high levels of CRH induced by chronic stress cannot bind to CRHR1 receptor，thereby enhancing the expression of down-regulated mTOR / p70S6K signaling pathway.

Objective To investigate the facial spectrum and color characteristics of patients with essen-tial hypertension post administering antihypertensive drugs,establish a classification and evaluation model based on the facial colors of the enrolled patients,and perform in-depth analysis on the important characteristics of their facial spectrum.Methods From September 3,2018,to March 23,2024,participants with essential hyperten-sion(receiving antihypertensive medication treatment,hypertension group)and normal blood pressure(control group)were recruited from the Cardiology Department of Shanghai Hospital of Traditional Chinese Medicine,the Coronary Care Unit of Shanghai Tenth People's Hospital,the Physical Examination Center of Shuguang Hospital Affiliated to Shanghai Uni-versity of Traditional Chinese Medicine,and the Gaohang Community Health Service Center.This study employed the propensity score matching(PSM)method to reduce study partici-pants selection bias.Spectral information in the facial visible light spectrum of the subjects was collected using a flame spectrometer,and the spectral chromaticity values were calculat-ed using the equal-interval wavelength method.The study analyzed the differences in spec-tral reflectance across various facial regions,including the entire face,forehead,glabella,nose,jaw,left and right zygomatic regions,left and right cheek regions as well as differences in parameters within the Lab color space between the two subject groups.Feature selection was conducted using least absolute shrinkage and selection operator(LASSO)regression,fol-lowed by the application of various machine learning algorithms,including logistic regres-sion(LR),support vector machine(SVM),random forest(RF),Na?ve Bayes(NB),and eX-treme Gradient Boosting(XGB).The reduced-dimensional dataset was split in a 7:3 ratio to establish a classification and assessment model for facial coloration related to primary hyper-tension.Additionally,model fusion techniques were applied to enhance the predictive power.The performance of the models was evaluated using metrics including the area under the curve(AUC)and accuracy.Shapley Additive exPlanations(SHAP)was used to interpret the outcomes of the models.Results A total of 114 participants were included in both hypertension and control groups.Reflectance analysis across the entire face and eight predefined areas revealed that the hypertensive group exhibited significantly higher reflectance of corresponding color light in the blue-violet region(P<0.05)and a lower reflectance in the red region(P<0.05)compared with control group.Analysis of Lab color space parameters across the entire face and eight predefined areas showed that hypertensive group had significantly lower a and b values than control group(P<0.05).LASSO regression analysis identified a total of 18 facial color features that were highly correlated with hypertension,including the a values of the chin and the right cheek,the reflectance at 380 nm and at 780 nm of the forehead.The results of the multi-mod-el classification showed that the RF classification model was the most effective,with an AUC of 0.74 and an accuracy of 0.77.The combined model of RF+LR+SVM outperformed a single model in their classification performance,achieving an AUC of 0.80 and an accuracy of 0.76.SHAP model visualization results indicated that the top three contributors to ideal prediction results based on the characteristics from the facial spectrum were the reflectance at 380 nm across the entire face and of the nose as well as the a value of the chin.Conclusion Within the same age group,patients with essential hypertension exhibited signif-icant and regular changes in facial color and facial spectral reflectance parameters after the administration of antihypertensive drugs.Furthermore,facial reflectance indicators,such as the overall reflectance at 380 nm and the a value of the chin,could offer valuable references for clinically assessing the drug efficacy and health status of patients with essential hyperten-sion.

Abstract: To investigate the protective effect and mechanisms of silent information regulator 1(SIRT1) agonist resveratrol on monocrotaline-induced Hepatic sinusoidal obstruction syndrome(HSOS) in rats. Methods: Thirty-two male Sprauge-Dawley(SD) rats were randomly divided into three group, with 8 rats in the control group and 12 rats in each of the monocrotaline group and resveratrol group. The monocrotaline group and resveratrol group were given monocrotaline(160 mg/kg) by single gavage. The resveratrol group was intraperitoneally injected with resveratrol solution [30 mg/(kg·d)] one day before intragastric administration. The experiment was terminated 2 days after the monocrotaline administration. Serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bilirubin(TBiL), glutathione(GSH) and malondialdehyde(MDA) in liver homogenate were detected. The pathological change of liver tissue was observed. The protein expression levels of SIRT1, hypoxia-inducible factor-1α(HIF-1α), and vascular endothelial growth factor(VEGF) in liver were detected by Westernblot. Results: Compared with the control group, the serum ALT, AST and TBiL in monocrotaline group increased(allP<0.01), GSH in liver homogenate decreased(P<0.01), MDA increased(P<0.01). Disordered arrangement, degeneration and necrosis of liver cells, congestion and dilation of hepatic sinuses and damage of central vein endothelium were observed. SIRT1 decreased(P<0.01), HIF-1α and VEGF protein expression increased(allP<0.01). After resveratrol treatment, serum ALT, AST and TBiL obviously decreased(P<0.05;P<0.05;P<0.01). GSH in liver homogenate increased(P<0.01), MDA decreased(P<0.01). And resveratrol also could inhibit the liver pathological damage caused by monocrotaline. SIRT1 protein expression increased(P<0.01), HIF-1α and VEGF protein expression also decreased(allP<0.01). Conclusion Resveratrol can improve Hepatic sinusoidal obstruction syndrome caused by monocrotaline in rats, and the mechanism is related to its activation of SIRT1, inhibition of HIF-1α/VEGF signaling pathway and antioxidanion.

Objective:To explore the related factors of poor prognostis in children with Henoch-Sch?nlein purpura nephritis (HSPN), and provide reference for predicting and improving the prognosis of children with HSPN.Methods:The clinical and pathological data of children with HSPN hospitalized in the Department of Nephrology, Children's Hospital Affiliated to Capital Institute of Pediatrics from May 2007 to June 2019 were retrospectively reviewed. According to the prognosis, the patients were divided into complete remission group and persistent abnormal group.Results:(1) Among 108 cases, there were 73 males and 35 females, with the onset age ranging from 5 to 16 years and average age of (9.5±2.8) years. The interval time from the first clinic in our hospital to the last follow-up was 2-131 months, with average of 24.8 months. Renal involvement occurred in the course of Henoch-Sch?nlein purpura from 1 day to 51 months, and the renal biopsy time was 5 days to 60 months after renal involvement. (2) Hematuria with proteinuria type and nephrotic syndrome type were predominant, and there was no significant difference between the two groups. The proportion of gross hematuria in the persistent abnormal group were significantly higher than that in the complete remission group (52.6% vs 31.4%, χ2=4.659, P=0.031). There were significant differences in serum creatinine and urea between the two groups (both P<0.05). The proportion of hyperuricemia in the persistent abnormal group was higher than that in the complete remission group (39.5% vs 21.4%, χ2=3.998, P=0.046). After clinical treatment, though there was no significant difference in proteinuria between the two groups at the beginning of the disease, the negative transformation rate of proteinuria in the complete remission group was higher than that in the persistent abnormal group after 3 months (55.7% vs 34.2%, χ2=4.562, P=0.033). (3) According to International study of Kidney Disease in Children (ISKDC) pathology classification, 14 cases (36.8%), 21 cases (55.3%), 3 cases (7.9%) withⅡ, Ⅲ, Ⅳ level in the persistent abnormal group and 21 cases (30.0%), 49 cases (70.0%), 0 case with Ⅱ, Ⅲ, Ⅳ level (70.0%) in the complete remission group after (20.16±24.86) months of follow-up, and the difference between the two groups was not statisticcally significant ( Z=-0.135, P=0.892). According to the Oxford Classification of IgA nephropathy, 36(33.3%) children had tubule-interstitial lesions (T1, 26%-50% tubular atrophy or interstitial fibrosis), and the proportion in the persistent abnormal group was significantly higher than that in the complete remission group (50.0% vs 24.3%, Z=-2.695, P=0.007). (4) Compared with T0 (0-25% tubular atrophy or interstitial fibrosis), the incidence of gross hematuria and hyperuricemia in the T1 tubule-interstitial lesion were both higher than that (respectively 63.9% vs 27.8%, χ2=13.061, P<0.001; 38.9% vs 22.2%, χ2=3.983, P=0.046). (5) Multivariate logistic regression analysis showed that renal tubule-interstitial lesion was a risk factor for poor prognosis of HSPN ( OR=2.580, 95% CI 1.055-6.310, P=0.038). Conclusions:Renal tubule-interstitial lesion is a risk factor for the persistent abnormal of HSPN. Gross hematuria and hyperuricemia are related to tubule-interstitial lesions.

Objective To examine role and possible mechanism of enriched environment (EE) on regulating recovery of visual function in adult monocular deprivation amblyopia mice.Methods A total of 72 healthyKunming mice were divided into normal control group,monocular deprivation (MD) group,MD+EE group and M D+ fluoxetine group by random number table.Except for the normal control group,the mice in the other groups were sutured on the right eyelid 21 days after birth to establish MD amblyopia model.the mice were fed in standard environment or EE for 4 weeks according to the group.Visual acuity and flash visual evoked potential (F-VEP) of mice in each group were detected.The distribution of microtubule associated protein 2 (MAP2) in visual cortex of adult amblyopic mice were detected by immunohistochemistry.The expression of MAP2,synaptophysin (SYP) and postsynaptic density protein-95 (PSD-95) protein in visual cortex of adult amblyopic mice were detected by western blot.The experimental protocol was approved by the Animal Care and Use Committee of Hunan Children's Hospital and conformed to the National Institutes of Health Guide for the Care and Use of Laboratory Animals.Results There was a significant difference in the visual acuity of deprived eye among each group (F=114.632,P＜0.001).The visual acuity in MD group is lower than that in normal control group,with a significant difference (t =15.480,P＜0.001).Compared with MD group,visual acuity was restored in MD+ EE group and MD +fluoxetine group,with significant differences (t =15.071,P ＜ 0.001;t =14.841,P ＜ 0.001).There was a significant difference in the P2 latency and amplitude of F-VEP in deprived eye among each group (F=36.510,P=0.000;F=34.140,P=0.000).Compare with normal control group,P2 latency was prolonged and P2 amplitude of F-VEP was decreased in deprived eye in MD group,with significant differences (t =10.220,P =0.000;t =10.09,P =0.000).Western blot assay showed that there was a significant difference in the expression of MAP2 in visual cortex contralateral deprived eye among each group (F=18.142,P=0.000).The expression of MAP2 in MD group was significantly lower than that in normal contral group (t=3.056,P＜0.01);Compared with MD group,MAP2 expression was increased in MD+EE group and MD+fluoxetine group (t =2.541,P =0.031;t =2.157,P =0.017).There were significant differences in the expression of SYP and PSD-95 in visual cortex contralateral to deprived eye among each group (F =12.871,P =0.000;F =25.060,P =0.000).Compared with normal contral group,SYP and PSD-95 expression in visual cortex were down-regulated in MD group,with significant differences (t =6.054,P =0.000;t =8.631,P =0.000).The expression of SYP and PSD-95 protein in MD+EE group and MD+fluoxetine group were significantly higher than those in MD group (all at P＜0.05).Conclusions EE can recover visual function through up-regulating the expression of MAP2,which can modulate the dendritic branch trim and neural plasticity of visual cortex in adult MD mice.

Objective To investigate the effects of hyperbaric oxygen ( HBO ) combined with Naoxintong capsules on serum BDNF, TGF-beta 1 and endothelial function of the patients with hypertensive intracerebral hemorrhage. Methods Eighty patients with hypertensive intracerebral hemorrhage who were hospitalized from November 2016 to November 2018 were randomly divided into the observation group and the control group, each consisting of 40 patients. The control group took Naoxintong capsules 3 times a day, while the treatment group was supplemented with HBO therapy in addition to the treatment received by the control group. The clinical efficacy, NIHSS scores, Barthel indexes, endothelial function and serum levels of brain-derived neurotrophic factor ( BDNF) and changes in the levels of TGF-beta 1 were closely observed. Results After 3 courses of treatment, the total effective rate of the observation group (90. 0％) was obviously higher than that (72. 5％) of the control group (P<0. 05). Following treatment, the NIHSS scores of the 2 groups were all lower than those before treatment, and the scores of the observation group after treatment were lower than those of the control group after treatment (P<0. 05 or P<0. 01). The BI scores of the 2 groups after treatment all elevated, as compared with those before treatment, and the scores of the observation group after treatment were higher than those of the control group after treatment (P<0. 05 or P<0. 01). The NO levels of the 2 groups after treatment all increased prominently as compared with those before treatment, and the NO level of the observation group after treatment were higher than those of the control group after treatment (P<0. 05 or P<0. 01). The ET-1 levels of the 2 groups after treatment all decreased considerably as compared with those before treatment, and the ET-1 level of the observation group after treatment was lower than that of the control group after treatment (P<0. 05 or P<0. 01). As compared with those before treatment, the BDNF and TGF-β-1 levels of the 2 groups after treatment all elevated markedly, and those of the observation group after treatment were higher than those of the control group after treatment (P<0. 05 or P<0. 01). Conclusion Through the regulation of serum BDNF and TGF-β1 levels and the decrease of inflammatory response, HBO combined with Naoxintong capsules could improve neuroendothelial function in the patients with hypertensive intracerebral hemorrhage, with sound clinical efficacy and good safety. For this reason, it was worth further clinical promotion.
