Objective To investigate the clinical effect of superficial temporal artery-middle cerebral artery anastomosis(STA-MCA)in the treatment of patients with occlusive cerebrovascular disease.Methods A total of 74 patients with occlusive cerebrovascular disease admitted to our hospital were included and divided into the observation group and control group according to the random number table method,with 37 cases in each group.Patients in the control group received conservative treatment,and patients in the observation group received STA-MCA.After 3 months of follow-up,the cerebral blood flow indexes(including cerebral blood flow of anterior cerebral artery,and peak time)before treatment and 3rd day,1st month and 3rd month after treatment were observed,the modified Rankin scores before treatment and 3rd day and 1 month after treatment were recorded,and the revascularization and occurrence of complications after treatment were recorded.Results At 1 month and 3 months after treatment,the cerebral blood flow of anterior cerebral artery in the two groups increased and the peak time was shortened,and the cerebral blood flow of anterior cerebral artery in the observation group was higher than that in the control group,and the peak time was shorter than that in the control group,with statistically significant differences(P<0.05).The modified Rankin scores of the two groups 1 month after treatment were lower compared with those before treatment,and the modified Rankin score of the observation group was lower than that of the control group,with statistically significant differences(P<0.05).At 1 month after treatment,the proportions of patients with grades 0 and 1 of vascular reconstruction in the observation group were lower than those in the control group,and the proportions of patients with grades 2 and 3 were higher than those in the control group,with statistical significant differences(P<0.05).At 3 months after treatment,the proportions of patients with grades 0 and 1 of vascular reconstruction in the observation group were lower than those in the control group,and the proportion of patients with grade 3 of vascular reconstruction was higher than that in the control group,with statistically significant differences(P<0.05).There was no statistically significant difference in the total incidence of complications after treatment between the two groups(P>0.05).Conclusion STA-MCA has a good clinical effect in the treatment of patients with occlusive cerebrovascular disease,which is conducive to improving the cerebral blood flow indexes and promoting the recovery of neurological function and vascular reconstruction,with safety and reliability.

Objective·To explore the effect of double homeobox(DUX)protein on the differentiation potential of mouse embryonic stem cells(mESCs)into extraembryonic endoderm(XEN)and the possible mechanism of its action.Methods·Overexpression of DUX cell lines in mESCs was achieved by using a lentiviral system.The proportion of 2-cell-like cells(2CLCs)before and after DUX overexpression was detected by flow cytometry,and the expression of 2-cell stage-specific genes,Dux,zinc finger and SCAN domain containing 4c(Zscan4c),zinc finger protein 352(Zfp352)and murine endogenous retrovirus-L polymerase(MERVL-pol),were detected by real-time quantitative reverse transcription polymerase chain reaction(RT-qPCR).RT-qPCR assay was used to detect the expression of pluripotency factors,nanog homeobox(Nanog),kruppel-like transcription factor 4(Klf4),sex determining region Y-box 2(Sox2),and octamer-binding transcription factor 4(Oct4),in pluripotent state,as well as the expression of signature genes for different germ layers in the differentiated state[endodermal:GATA binding protein 4(Gata4),GATA binding protein 6(Gata6),and sex determining region Y-box 17(Sox17);ectodermal:Nestin and tubulin beta 3 class Ⅲ(Tubb3);mesodermal:heart and neural crest derivatives expressed 1(Hand1),myogenic differentiation 1(Myod1),and kinase insert domain protein receptor(Flk1)].Public RNA sequencing(RNA-seq)data were mined to further clarify the effect of DUX on the differentiation of mESCs into extraembryonic endoderm.Functional and pathway enrichment analyses of differentially expressed genes were performed using Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG),and gene set enrichment analysis(GSEA)to identify the signaling pathways regulated by DUX.Additionally,an in-depth analysis of existing chromatin immunoprecipitation sequencing(ChIP-seq)data was conducted to explore the potential target genes of DUX.Results·Molecular biology experiments showed that overexpression of DUX could effectively maintain the pluripotency of mESCs,which was consistent with the analysis of public RNA-seq data.Differential gene analysis revealed that endodermal genes were specifically upregulated.After differentiation assay of mESCs,RT-qPCR assay experiments showed that mRNA expression of the XEN marker genes(Gata4,Gata6,Sox17)was significantly upregulated(P<0.001).In contrast,there was no specific change in mesodermal and ectodermal genes.GSEA enrichment analysis indicated that DUX might activate the retinoid metabolism signaling pathway,and the analysis of the ChIP-seq data further revealed the presence of a large number of known retinoic acid receptor motif in DUX-bound peaks,which could activate downstream target genes related to the development of the XEN.Conclusion·DUX has a strong correlation with the retinoic acid signaling pathway and it is predicted to activate the retinoic acid signaling pathway,which could promote the tendency of mESCs toward XEN differentiation.

Objective:We aimed to develop a novel visualized model based on nomogram to predict postoperative overall survival.Methods:This was a multicenter, retrospective, observational cohort study, including participants with histologically confirmed gastric and colorectal cancer who underwent radical surgery from 11 medical centers in China from August 1, 2015 to June 30, 2018. Baseline characteristics, histopathological data and nutritional status, as assessed using Nutrition Risk Screening 2002 (NRS 2002) score and the scored Patient-Generated Subjective Global Assessment, were collected. The least absolute shrinkage and selection operator regression and Cox regression were used to identify variables to be included in the predictive model. Internal and external validations were performed.Results:There were 681 and 127 patients in the training and validation cohorts, respectively. A total of 188 deaths were observed over a median follow-up period of 59 (range: 58 to 60) months. Two independent predictors of NRS 2002 and Tumor-Node-Metastasis (TNM) stage were identified and incorporated into the prediction nomogram model together with the factor of age. The model's concordance index for 1-, 3- and 5-year overall survival was 0.696, 0.724, and 0.738 in the training cohort and 0.801, 0.812, and 0.793 in the validation cohort, respectively.Conclusions:In this study, a new nomogram prediction model based on NRS 2002 score was developed and validated for predicting the overall postoperative survival of patients with gastric colorectal cancer. This model has good differentiation, calibration and clinical practicability in predicting the long-term survival rate of patients with gastrointestinal cancer after radical surgery.

Confirmed cases of Lyme disease(LD)in Ji'an City,Jiangxi Province and the clinical manifestations and region-al distribution were assessed to provide a basis for timely diagnosis and treatment.In total,133 serum samples were collected from patients with suspected LD in Ji'an Central People's Hospital from December 2021 to August 2022.Serum antibodies a-gainst Borrelia burgdorferi were detected with a two-step testing process.In addition,a specific gene of B.burgdorferi in samples was identified by nested PCR.Sequencing analysis was conducted to confirm the positive samples.Overall,25(18.80％)serum samples were positive for B.burgdorferi nucleic acid and antibodies,which included 20(15.04％)positive for antibodies and 6(4.51％)positive for nucleic acids.The sequences of the 5S-23S rRNA gene spacer of 6 samples were con-sistent with the corresponding sequences of Borrelia yangtzensis and one of the six samples was also positive for antibodies.The 25 positive samples were collected from 9 counties in Ji'an City,with the majority in Jizhou District(44％).All positive patients may experience symptoms related to LD,including joint disorders,neurological disorders,infectious fever,der-matitis,and/or chest pain.The most common symptom was joint disorders(72％).Six cases positive for B.yangtzensis nucleic acids were mainly collected in the Jizhou District,of which four had joint lesions and two had infectious fever.This study confirms the existence of LD in Jiangxi Province,which may be the first confirmation of human infection with B.yan-gtzensis in southern China.Hence,doctors in this region should consider the possibility of LD for cases presenting with related symptoms.Although LD may occur in this region,further investigations and monitoring are warranted.

The identification of the components absorbed in serum of platycosides in total saponins fraction of Platycodonis Radix is great significance, but there are still great challenges. In this study, 8 types of 44 primordial components from Platycodon saponins were firstly identified using the ultra-performance liquid chromatography-linear ion trap electrostatic field orbitrap high resolution mass spectrometry (UPLC-LTQ-Orbitrap-MS) equipped with the software of Compound Discoverer 3.2 and Trace finder 2.1. Then, the platycosides and their deglycosylated metabolites were used as the template molecules to construct the intestinal microbiota mediated method to identify the primary components and the prototypes in serum. As results, 57 components originating from 44 prototypes of platycosides were identified from drug-containing plasma. Those compounds consist of 12 prototypes of platycosides and 45 metabolites, while the prototypes in serum are also deglycosylated metabolites of other platycosides. The results showed that the intestinal microbiota mediated method could be applied to identify the metabolites of platycosides in total saponins fraction of Platycodonis Radix; and reveal the potential existing forms of prototypes of platycosides in plasma; In addition, it could clearly illustrate the one to many and many to one network of the prototypes and metabolites of platycosides. All animal protocols were approved by the Animal Ethics Committee of Jiangxi University of Traditional Chinese Medicine (No.JZLLSC-202100322).

Uric acid (UA) is the final product of purine metabolism in human body,and its metabolic disorder will induce hyperuricemia (HUA).The occurrence and development of HUA are associated with a variety of pathological mechanisms such as oxidative stress injury,activation of inflammatory cytokines,and activation of renin-angiotensin-aldosterone system.These mechanisms directly or indirectly affect the bioavailability of endogenous nitric oxide (NO).The decrease in NO bioavailability is common in the diseases with high concentration of UA as an independent risk factor.In this review,we summarize the mechanisms by which high concentrations of UA affect the endogenous NO bioavailability,with a focus on the mechanisms of high-concentration UA in decreasing the synthesis and/or increasing the consumption of NO.This review aims to provide references for alleviating the multisystem symptoms and improving the prognosis of HUA,and lay a theoretical foundation for in-depth study of the correlations between HUA and other metabolic diseases.

Objective: To analyze the association between body mass index (BMI) and coronary heart disease. Methods: The data for the present study were from the prospective cohort study of China Kadoorie Biobank (CKB) in Qingdao, a total of 33 355 participants aged 30-79 years were included in the study. Cox regression analyses were performed to evaluate the association between BMI and coronary heart disease. Results: During the follow-up for an average 9.2 years, a total of 2 712 cases of ischemic heart disease (IHD) and 420 cases of major coronary events (MCE) were found. Multivariate Cox regression analysis showed that, compared with participants with normal BMI, the participants who were overweight had a 41% and 87% higher risk of IHD and MCE, the adjusted HR were 1.41 (95%CI: 1.27-1.56) and 1.87 (95%CI: 1.43-2.44), respectively. The participants who were obesity had 91% and 143% higher risk of IHD and MCE, the adjusted HR were 1.91 (95%CI: 1.72-2.13) and 2.43 (95%CI: 1.82-3.24), respectively. Conclusion: Overweight and obesity might increase the risk for IHD and MCE.

OBJECTIVES: To investigate the preadmission follow-up condition of neonates hospitalized due to severe hyperbilirubinemia after discharge from the department of obstetrics and the influencing factors for follow-up compliance. METHODS: A multicenter retrospective case-control study was performed for the cases from the multicenter clinical database of 12 units in the Quality Improvement Clinical Research Cooperative Group of Neonatal Severe Hyperbilirubinemia in Jiangsu Province of China from January 2019 to April 2021. According to whether the follow-up of neonatal jaundice was conducted on time after discharge from the department of obstetrics, the neonates were divided into two groups: good follow-up compliance and poor follow-up compliance. The multivariate logistic regression model was used to identify the influencing factors for follow-up compliance of the neonates before admission. RESULTS: A total of 545 neonates with severe hyperbilirubinemia were included in the study, with 156 neonates (28.6%) in the good follow-up compliance group and 389 (71.4%) in the poor follow-up compliance group. The multivariate logistic regression analysis showed that low gestational age at birth, ≥10% reduction in body weight on admission compared with birth weight, history of phototherapy of siblings, history of exchange transfusion of siblings, Rh(-) blood type of the mother, a higher educational level of the mother, the use of WeChat official account by medical staff to remind of follow-up before discharge from the department of obstetrics, and the method of telephone notification to remind of follow-up after discharge were associated with the increase in follow-up compliance (P<0.05). CONCLUSIONS Poor follow-up compliance is observed for the neonates with severe hyperbilirubinemia after discharge from the department of obstetrics, which suggests that it is necessary to further strengthen the education of jaundice to parents before discharge and improve the awareness of jaundice follow-up. It is recommended to remind parents to follow up on time by phone or WeChat official account.

Objective:To observe the difference in drying dampness between Scutellariae Radix and Atractylodis Rhizoma in model rats with spleen-stomach dampness-heat syndrome and clarify their property-efficacy relationship. Method:Sixty-four healthy male SD rats were randomized into the blank group， model group， high-， medium-， and low-dose Scutellariae Radix groups， as well as high-， medium-， and low-dose Atractylodis Rhizoma groups. The rats were exposed to high-fat and high-sugar diet and external dampness-heat environment for 20 days for inducing the spleen-stomach dampness-heat syndrome. The macroscopic manifestations of rats were observed and the morphological changes in stomach and colon were detected under a light microscope after hematoxylin-eosin （HE） staining， followed by the calculation of pathological scores. The serum tumor necrosis factor-α （TNF-α）， interleukin-4 （IL-4）， and interferon-γ （IFN-γ） levels were determined by enzyme-linked immunosorbent assay （ELISA）. The protein and mRNA expression levels of aquaporin-4 （AQP4） in the gastric tissue were measured by Western blot and Real-time polymerase chain reaction （Real-time PCR）， respectively. Result:Rats in the model group presented with the manifestations of dampness-heat syndrome. The inflammatory reaction in stomach and colon was obvious， and the pathological score was significantly increased （P<0.01）. The serum IFN-γ， IL-4， and TNF-α levels were elevated （P<0.05）， and so were the AQP4 protein and mRNA expression levels in the gastric tissue except that there was no statistical difference. The clinical symptoms of rats in the medication groups were alleviated. Scutellariae Radix significantly relieved the gastric and colonic inflammation in model rats. Atractylodis Rhizoma inhibited the colonic inflammation in model rats to a certain extent， but it had no obvious effect on gastric inflammation. The pathological score of each Scutellariae Radix group was decreased. In terms of the pathological score of gastric tissue， only the high-dose Scutellariae Radix produced a significant difference （P<0.01）， and the pathological scores of the three Atractylodis Rhizoma groups were not significantly different from that in the model group. As for the pathological score of colonic tissue， all the medication groups except for the low-dose Atractylodis Rhizoma group exhibited a significant difference in comparison with that of the model group （P<0.01）. Scutellariae Radix and Atractylodis Rhizoma at each dose reduced not only the serum IFN-γ， IL-4， and TNF-α levels （P<0.05， P<0.01）， but also the AQP4 protein expression in gastric tissue of model rats （P<0.01）. The AQP4 mRNA expression in the gastric tissue of model rats declined in the high- and low-dose Scutellariae Radix groups， while that in the medium-dose Scutellariae Radix group and each Atractylodis Rhizoma group rose without statistical difference. Conclusion:Scutellariae Radix and Atractylodis Rhizoma display a certain property-efficacy relationship in drying dampness of rats with spleen-stomach dampness-heat syndrome. Specifically， the efficacy of drying dampness is related to their cold/heat property， and the resulting outcome of bitter-cold Scutellariae Radix is better than that of bitter-warm Atractylodis Rhizoma.

OBJECTIVE: To observe the effect of conventional acupuncture combined with row-like puncture at sternocleidomastoid on peripheral facial palsy at recovery stage. METHODS: A total of 60 patients with peripheral facial palsy at recovery stage were randomized into an observation group and a control group, 30 cases in each one. Acupuncture was applied at affected Cuanzhu (BL 2), Yangbai (GB 14), Sibai (ST 2), Quanliao (SI 18), Jiache (ST 6), Dicang (ST 4), Hegu (LI 4), Taichong (LR 3) and Zusanli (ST 36) in the control group. On the basis of the treatment in the control group, row-like puncture was applied at sternocleidomastoid (1 needle was punctured at muscle origin and insertion respectively, 3 to 4 needles were row-like punctured at the connection line of muscle origin and insertion). The treatment was given once a day, 5 times were as one course, with 2-day interval, totally 4 courses were required in the both groups. The house-brackmann (H-B) facial nerve function grade, facial nerve function rating system-dynamic view rating scale score and facial disability index (FDI) scale score [including scores of FDI physical function (FDIp) and FDI social life function (FDIs)] before and after treatment were observed, and the clinical efficacy was evaluated in the two groups. RESULTS: After treatment, the H-B facial nerve function grades were improved compared before treatment in the both groups ( CONCLUSION Compared with conventional acupuncture, combination therapy with row-like puncture at sternocleidomastoid can improve the therapeutic effect of peripheral facial palsy at recovery stage.
