According to the principle and current domestic and international construction processes of core outcome set(COS) and the characteristics of post-stroke aphasia, this study built COS with evidence-based support for traditional Chinese medicine(TCM) treatment of post-stroke aphasia. Firstly, a comprehensive review was conducted on the articles about the TCM treatment of post-stroke aphasia that were published in the four major Chinese databases, three major English databases, and three clinical registration centers over the past five years. The articles were analyzed and summarized, on the basis of which the main part of the COS for clinical research on the TCM treatment of post-stroke aphasia was formed. Secondly, clinical doctors and related nursing personnel were interviewed, and important outcome indicators in the clinical diagnosis and treatment process were supplemented to form a pool of core outcome indicators. Two rounds of Delphi surveys were carried out to score the importance of the core outcome indicators in the pool. Finally, a consensus meeting of experts was held to establish the COS for clinical research on the TCM treatment of post-stroke aphasia. The final COS included a total of 268 studies [236 randomized controlled trials(RCTs), 21 Meta-analysis, and 11 clinical registration protocols] and 20 open questionnaire survey results. After two rounds of Delphi surveys, a total of 14 outcome indicators and their corresponding measurement tools were included in the expert consensus meeting. The final expert consensus meeting determined the COS for post-stroke aphasia, which included 9 indicator domains and 12 outcome indicators.

OBJECTIVE: To investigate the short-term efficacy and safety of low-dose venetoclax combined with CHG (cytarabine+homoharringtonine+G-CSF) priming regimen in patients with acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS) ineligible for intensive chemotherapy. METHODS: The data of 14 patients with AML or high-risk MDS admitted to the department of hematology/oncology of the First Hospital of Tsinghua University and 2 cooperative institutions from July 2022 to August 2023 were retrospectively analyzed. All the patients were treated with low-dose venetoclax combined with CHG priming regimen and the early induction (one course) efficacy and adverse reactions were observed. RESULTS: Among the 14 patients, 10 were males and 4 were females, with a median age of 69.5 (46-83) years. After 1 cycle of induction chemotherapy, the complete remission (CR) rate was 64.3% (9/14) and overall response rate (ORR) was 78.6% (11/14). Among the 10 patients with adverse prognosis according to cytogenetics and molecular genetics, the CR rate was 50.0% (5/10), and ORR was 70.0% (7/10). In 7 patients with TP53 mutation, the CR rate was 42.9% (3/7) and ORR was 71.4% (5/7). In the 6 patients with complex karyotype, CR rate was 33.3% (2/6) and ORR was 66.7% (4/6). While the CR rate and ORR of 8 non-complex karyotype patients were both 87.5% (7/8), and the difference in CR rate between patients with complex karyotype and non-complex karyotype was statistically significant ( P < 0.05). The adverse reactions of chemotherapy were tolerable, without early treatment-related deaths. CONCLUSION Low-dose venetoclax combined with CHG priming regimen can be used as an effective treatment for AML and high-risk MDS patients who are ineligible for intensive chemotherapy, and it is safe and worthy of clinical application.

OBJECTIVE: To assess the independent and combined effects of air pollutants, meteorological factors, and greenspace exposure on new tuberculosis (TB) cases. METHODS: TB case data from Shanghai (2013-2018) were obtained from the Shanghai Center for Disease Control and Prevention. Environmental data on air pollutants, meteorological variables, and greenspace exposure were obtained from the National Tibetan Plateau Data Center. We employed a distributed-lag nonlinear model to assess the effects of these environmental factors on TB cases. RESULTS: Increased TB risk was linked to PM _2.5, PM ₁₀, and rainfall, whereas NO ₂, SO ₂, and air pressure were associated with a reduced risk. Specifically, the strongest cumulative effects occurred at various lags: PM _2.5 ( RR = 1.166, 95% CI: 1.026-1.325) at 0-19 weeks; PM ₁₀ ( RR = 1.167, 95% CI: 1.028-1.324) at 0-18 weeks; NO ₂ ( RR = 0.968, 95% CI: 0.938-0.999) at 0-1 weeks; SO ₂ ( RR = 0.945, 95% CI: 0.894-0.999) at 0-2 weeks; air pressure ( RR = 0.604, 95% CI: 0.447-0.816) at 0-8 weeks; and rainfall ( RR = 1.404, 95% CI: 1.076-1.833) at 0-22 weeks. Green space exposure did not significantly impact TB cases. Additionally, low temperatures amplified the effect of PM _2.5 on TB. CONCLUSION Exposure to PM _2.5, PM ₁₀, and rainfall increased the risk of TB, highlighting the need to address air pollutants for the prevention of TB in Shanghai.

Objective:To discuss the effect of prostaglandin E2(PGE2),a pyrogenic mediator,on the discharge activity of warm-sensitive neurons(WSNs)in median preoptic nucleus(MnPO)of hypothalamus in the female mice,and to clarify its mechanism.Methods:Coronal brain slices of MnPO were prepared from the female mice.The slices were then perfused with artificial cerebrospinal fluid(ACSF)containing synaptic transmission blockers(STBs).The discharge frequency was monitored using the patch clamp technique while changing the temperature of the perfusate to identify the WSNs.A total of 32 MnPO WSNs were divided into base line group(n=32)and PEG2(n=32).The patch clamp technique was employed to monitor the discharge frequencies of MnPO WSNs following the perfusion of ACSF and 1 μmol·L-1 PGE2,respectively.The MnPO WSNs with good activity and significant change in discharge frequency after PGE2 perfusion were divided into PGE2 receptor E-series prostaglandin receptrol(EP)1 antagonist(EP1 ant)+PGE2 group(n=7),EP3 ant+PGE2 group(n=7),and EP4 ant+PGE2 group(n=7).The patch clamp technique was used to monitor the discharge frequencies of MnPO WSNs following the perfusion of 3 μmol·L-1 EP1 ant and 1 μmol·L-1 PGE2 mixture,10 μmol·L-1 EP3 ant and 1 μmol·L-1 PGE2mixture,and 10 μmol·L-1 EP4 ant and 1 μmol·L-1 PGE2 mixture,respectively.Resluts:After perfuson of the ACSF containing STBs,a total of 188 MnPO neurons from the female mice with an intrinsic temperature sensitivity coefficient(m value)were identified;out of these,32 neurons had an m value of ≥0.8 and were identified as MnPO WSNs,accounting for approximately 17％of all recorded neurons.Compared with baseline discharge frequency,the discharge frequency of MnPO WSNs after addition of PGE2 was decreased(P＜0.05).Compared with PGE2 group,the percentage change in discharge frequency of MnPO WSNs in EP3 ant+PGE2 group was significantly decreased(P＜0.05).Compared with PGE2 group,the percentage change in discharge frequency of MnPO WSNs in EP1 ant+PGE2 group had no significant difference(P＞0.05).Compared with PGE2 group,the percentage change in discharge frequency of MnPO WSNs in EP4 ant+PGE2 group had no significant difference(P＞0.05).Conclusion:In the female mice,WSNs make up approximately 17％of the total neurons in MnPO.PGE2 can directly inhibit the discharge activity of MnPO WSNs in the female mice through postsynaptic mechanism involving EP3 receptors.

Objective To investigate the epidemiological characteristics of knee osteoarthritis(KOA)among military personnel in plateau regions and to explore its risk factors.Methods From July 2023 to July 2024,a multi-stage stratified cluster random sampling method was employed to survey the prevalence of KOA and related risk factors among military personnel in the northwest plateau regions of China,covering different altitudes(1500-4500 m)and geographical areas(Gansu,Qinghai,Tibet,and Xinjiang).All study subjects were divided into KOA and non-KOA groups based on the presence or absence of KOA.Variables including age,gender,body mass index(BMI),education level,smoking status,military rank,military branch,service duration,regional altitude,annual average temperature,training duration,perceived training intensity,and history of knee injury were selected for univariate analyses between groups.Variables with P<0.05 in the univariate analyses were included in the binary multifactor logistic regression to identify risk factors for KOA.Results A total of 3000 questionnaires were distributed,and 2854 valid questionnaires were collected,with a response rate of 95.13%.The sample included 2584 males and 270 females,with 510 cases of KOA,resulting in a prevalence rate of 17.9%.Univariate analysis showed that there were statistically significant differences between KOA and non-KOA groups in terms of age,BMI,smoking status,military rank,military branch,service duration,regional altitude,annual average temperature,training duration,perceived training intensity,and history of knee injury(P<0.05).However,no significant differences were found in gender and education level(P>0.05).Binary multivariate logistic regression analysis revealed that older age(OR=1.382,P=0.017),higher BMI(P<0.01),smoking(OR=1.929,P<0.01),higher military rank(OR=1.485,P=0.007),being a member of the Armed Police(P<0.01),longer service duration(P<0.01),higher regional altitude(OR=1.459,P<0.01),lower annual average temperature(OR=1.188,P=0.001),longer training duration(P<0.01),higher perceived training intensity(OR=2.450,P<0.01),and history of knee injury(OR=2.768,P=0.002)were independent risk factors for KOA.Conclusions Older age,overweight/obesity,smoking,higher military rank,being a member of the Armed Police,longer service duration,higher altitude,cold climate,longer training duration,higher training intensity,and history of knee injury are independent risk factors for KOA among military personnel in the northwest plateau regions of China.

The pathogenesis of depression is complex, and some existing monoamine antidepressants have problems such as drug resistance or off-target failure. Traditional Chinese medicine has the characteristics of "multi-component and multi-target", and has been used in the treatment of depression in clinical practice. Yueju pill is effective in the treatment of depression. Geniposide and ligustrazine, the active ingredients of Gardeniae fructus and Ligusticum sinense 'Chuanxiong', play a key role in the treatment of depression. In this study, based on the neuroprotective activity of genipin and the rapid antidepressant activity of tetramethylpyrazine, a series of novel genipin derivatives were designed and synthesized through pharmacophore assembly principle, and their neuroprotective activity and antidepressant effect were investigated. The results showed that the novel genipin derivatives had well neuroprotective activity on the glutamate-induced HT-22 cell model, with compounds W-1 and W-3 showing better protective activity. In behavioral despair depression (BDD) model mice, compound W-3 was found to have better antidepressant activity than W-1 in tail suspension test and forced swimming test. Further study on the behavior of chronic unpredictable mild stress (CUMS) model mice showed that W-3 could significantly improve the depression-like behavior of model mice. All animal experiments were approved by the Experimental Animal Ethics Committee of Anhui University of Chinese Medicine (approval number: AHUCM-mouse-2022027). The effects of the preferred compound W-3 on protein kinase A (PKA), cAMP response element binding protein (CREB), brain-derived neurotrophic factor (BDNF), 5-hydroxytryptamine 1A (5-HT_1A) receptor, N-methyl-D-aspartate ionic glutamate receptor 2A (GluN2A) and N-methyl-D-aspartate ionic glutamate receptor 2B (GluN2B) were analyzed by Western blot. W-3 treatment significantly up-regulated the protein expression of PKA, CREB, BDNF and 5-HT_1A, and down-regulated the protein expression of GluN2A and GluN2B. The results of qRT-PCR were consistent with those of Western blot. According to the above results, compound W-3 has a potential antidepressant effect, and its mechanism may be related to the activation of PKA-CREB-BDNF signaling pathway by regulating the expression of GluN2A, GluN2B and 5-HT_1A receptor proteins.

Background: Genetic defects in the human thyroid-stimulating hormone (TSH) receptor (TSHR) gene can cause congenital hypothyroidism (CH). However, the biological functions and comprehensive genotype–phenotype relationships for most TSHR variants associated with CH remain unexplored. We aimed to identify TSHR variants in Chinese patients with CH, analyze the functions of the variants, and explore the relationships between TSHR genotypes and clinical phenotypes. Methods: In total, 367 patients with CH were recruited for TSHR variant screening using whole-exome sequencing. The effects of the variants were evaluated by in-silico programs such as SIFT and polyphen2. Furthermore, these variants were transfected into 293T cells to detect their Gs/cyclic AMP and Gq/11 signaling activity. Results: Among the 367 patients with CH, 17 TSHR variants, including three novel variants, were identified in 45 patients, and 18 patients carried biallelic TSHR variants. In vitro experiments showed that 10 variants were associated with Gs/cyclic AMP and Gq/11 signaling pathway impairment to varying degrees. Patients with TSHR biallelic variants had lower serum TSH levels and higher free triiodothyronine and thyroxine levels at diagnosis than those with DUOX2 biallelic variants. Conclusions We found a high frequency of TSHR variants in Chinese patients with CH (12.3%), and 4.9% of cases were caused by TSHR biallelic variants. Ten variants were identified as loss-of-function variants. The data suggest that the clinical phenotype of CH patients caused by TSHR biallelic variants is relatively mild. Our study expands the TSHR variant spectrum and provides further evidence for the elucidation of the genetic etiology of CH.

Objective To investigate the distribution of traditional Chinese medicine(TCM)syndromes in the patients with acute cerebral infarction,and to analyze the correlation of TCM syndromes with collateral circulation,cerebral blood perfusion and prognosis.Methods A total of 300 patients with acute cerebral infarction were selected.All patients underwent head-neck CT angiography(CTA)and CT perfusion imaging(CTP),and then were followed up for 30 days.The prognosis was evaluated by modified Rankin Scale(MRS)score.In addition,the dynamic evolution of TCM syndromes was observed to explore the correlation of TCM syndromes with collateral circulation,cerebral blood flow perfusion in the lesion area and prognosis.Logistic regression analysis was used to explore the influences of TCM syndromes,blood flow perfusion and collateral circulation establishment on stroke outcomes.Results(1)Highest incidences of syndrome elements of phlegm,blood stasis and wind were presented in ACI patients.The syndrome element of qi deficiency was predominated in the patients with anterior/posterior communicating artery opening and extracranial-to-intracranial collateral circulation establishment.On the first day of onset,the incidence of qi deficiency syndrome element in the good collateral circulation group was lower than that in the poor collateral circulation group(P＜0.05).On the 30th day after onset,the incidences of qi deficiency syndrome element and phlegm syndrome element in the good collateral circulation group were significantly lower than those in the poor collateral circulation group(P＜0.01).The results of correlation analysis showed that the score of qi deficiency was negatively correlated with regional cerebral blood volume(rCBV)of region of interest(r=-0.472,P＜0.05),and the score of yin deficiency was positively correlated with rCBV(r=-0.557,P＜0.01)on the first day of onset.The incidence of qi deficiency in the lesion area was relatively high in the patients of decreased rCBV(rCBV＜1.0 score)group(P＜0.01),while the incidence of yin deficiency in the lesion area was relatively high in the patients of elevated rCBV(rCBV＞1.0 score)group(P＜0.05).(2)The distribution of syndrome elements on the first day of onset showed that the incidence of qi deficiency syndrome element in the poor prognosis group was significantly higher than that in the good prognosis group(P＜0.01);on the 30th day after onset,the incidences of qi deficiency syndrome element and phlegm syndrome element in the good prognosis group was significantly lower than those in the poor prognosis group(P＜0.05 or P＜0.01).The incidence of phlegm syndrome element in the good prognosis group was significantly reduced on the 30th day after onset compared with that on the first day of onset(χ2=7.409,P＜0.01),while there was no significant difference shown in the poor prognosis group(P＞0.05).(3)Logistic regression analysis showed that syndrome elements(qi deficiency,phlegm),collateral circulation grading,and rCBV in the lesion area were the independent risk factors for stroke outcomes.Conclusion The acute cerebral infarction patients with poor collateral circulation,decreased blood perfusion and poor prognosis are predominated by qi deficiency syndrome element.Moreover,phlegm syndrome element is presented in the patients with poor prognosis throughout the course of disease.It is indicated that qi deficiency syndrome element and phlegm syndrome element play an important role in the pathogenesis and progression of acute cerebral infarction.

Objective To explore the clinicopathological characteristics,prognosis and influencing factors of different pathological subtypes of gastric signet ring cell carcinoma(GSRC).Methods A retrospective analysis was performed on the clinical data of 232 patients with GSRC collected from January 2016 to December 2018 in Lanzhou University Second Hospital.According to the WHO classification criteria for GSRC,the patients were divided into pure gastric signet-ring cell carcinoma(pGSRC,n=36)and mixed gastric signet-ring cell carcinoma(mGSRC,n=196).The follow-up as of September 30,2022,the survival analysis was done using Kaplan-Meier method,the univariate and multivariate Cox regression were performed to analyze the risk factors affecting the prognosis of GSRC patients.Results The median survival time of pGSRC and mGSRC patients was 41.0(6.0-70.0)months and 24.0(2.0-74.0)months,respectively.Kaplan-Meier analysis showed that combination with diabetes,anemia,tumor diameter,nerve invasion,lymphovascular invasion,T stage,N stage,GSRC pathological subtype,CA125 and tumor diameter could affect the overall survival(OS)of patients with GSRC after radical gastrectomy(P＜0.05),but Her-2,whether adjuvant chemotherapy or not and others elements had no significant effect on OS of GSRC patients after radical gastrectomy(P＞0.05).Univariate Cox regression analysis showed that the combination with diabetes(P=0.031),anemia(P=0.028),tumor diameter＞5 cm(P=0.009),nerve invasion(P=0.002),lymphovascular invasion(P=0.002),mGSRC pathological type(P=0.039),T2-T4 stage(P=0.001),N1-N4 stage(P=0.004),pTNM stage Ⅲ(P=0.044),the number of lymph node metastasis＞30(P=0.044)and CA125 positive(P=0.009)were related to the prognosis of patients with GSRC after radical gastrectomy.Multivariate Cox regression analysis showed that mGSRC pathological type(P=0.035),T2-T4 stage(P=0.003),CA125 positive(P=0.010)were independent risk factors for poor prognosis of patients with GSRC after radical gastrectomy.Conclusion Compared with pGSRC,patients with mGSRC at diagnosis have higher pTNM stages,more aggressive,and shorter median survival time.mGSRC pathological type,T2-T4 stage,and CA125 positive were all independent factors affecting the prognosis of patients with GSRC.

AIM To investigate the effects of total Astragalus saponins on the improvement of sarcopenia in a rat model of type 2 diabetes mellitus(T2DM).METHODS The rats were divided into the normal group for a normal feeding and the model group for the feeding of high-sugar and high-fat diet combined with intraperitoneal injection of STZ to establish a T2DM model.The successful model rats were randomly divided into the model group,the metformin group(0.2 g/kg)and the total Astragalus saponins group(80 mg/kg),and given corresponding doses of drugs by gavage.After 12 weeks administration,the rats had their FBG,postprandial blood glucose(PG2h)and wet weight of skeletal muscle measured;their serum levels of INS,C-peptide(C-P),IGF-1,TNF-α and IL-1β detected by ELISA;their morphological changes of skeletal muscle observed by HE staining;their protein expressions of PI3K,p-Akt,mTOR,S6K1,FoxO1 and Murf1 in skeletal muscle detected by Western blot;and their mRNA expressions of Pi3k,Akt and mtor in skeletal muscle detected by RT-qPCR method.RESULTS Compared with the model group,the total Astragalus saponins group displayed decreased levels of FBG,PG2h,OGTT-AUC,HOMA-IR,TNF-α and IL-1β(P＜0.01);increased levels of INS,C-P,IGF-1 and wet weight of skeletal muscle(P＜0.05,P＜0.01);improved skeletal muscle atrophy and increased protein expressions of PI3K,p-Akt,mTOR and S6K1 in skeletal muscle(P＜0.05,P＜0.01);decreased protein expressions of FoxO1 and Murf1(P＜0.05,P＜0.01);and increased mRNA expressions of Pi3k,Akt and mtor(P＜0.01).CONCLUSION The improvement effects of total Astragalus saponins on sarcopenia in T2DM rats may be associated with the regulation of PI3K/Akt/mTOR and PI3K/Akt/FoxO1 pathways.
