The inflammatory microenvironment is closely associated with the initiation and progression of osteoarthritis （OA）， specifically manifesting as macrophage activation， dysregulation of inflammatory cytokines， and redox imbalance. Following an overview of the pathological characteristics of the OA inflammatory microenvironment， this paper reviews the research progress on the mechanism of traditional Chinese medicine （TCM） intervening in OA by modulating the inflammatory microenvironment. It has been found that TCM monomers/active ingredients （such as total alkaloids from Strychnos nux-vomica ， quercetin， triptolide， etc.）， herb pairs （e.g. Angelica pubescens - Gentiana macrophylla ， Carthami Flos-Lycopodii Herba）， and TCM formulas （such as Zhuanggu jianxi formula， Duhuo jisheng decoction and Rongjin niantong formula， etc.） can inhibit macrophage activation， reduce the release of proinflammatory cytokines and the generation of reactive oxygen species by inhibiting multiple signaling pathways， including nuclear factor-κB， Wnt/ β -catenin， and mitogen-activated protein kinase， thereby alleviating the articular inflammatory microenvironment， restoring local joint homeostasis， and slowing the progression of OA.

Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder primarily caused by pathogenic variants in the TSC1 or TSC2 genes. It is characterized by multisystem hamartomatous lesions and neuropsychiatric manifestations. Here we report a young male patient with TSC involving multiple organs, caused by a heterozygous frameshift mutation in TSC2 (c.2071delC, p.Arg691Alafs^*7). The patient initially presented with classic facial angiofibromas and hypomelanotic macules, and subsequently developed psychiatric and behavioral disturbances with auditory hallucinations. Neuroimaging revealed an intracranial mass lesion, which was confirmed as a subependymal giant cell astrocytoma on postoperative histopathology following surgery performed at an outside institution. After admission, the patient underwent a comprehensive diagnostic workup, and multidisciplinary treatment evaluation revealed extensive multisystem involve-ment, including the nervous system, skin, kidneys, lungs, heart, eyes, pancreas, liver and bones. Combined with relevant literature, this article discusses the molecular mechanisms, clinical phenotypes, and comprehensive management of TSC, in order to provide a reference for the standardized and individualized management of this disease.

BackgroundBoth modified Suanzaoren Decoction and estazolam serve as effective treatments for chronic insomnia disorder （CID）. Default mode network （DMN） dysfunction is recognized as the primary pathophysiological mechanism underlying CID. However， it remains unclear whether the two treatments exert their therapeutic effects via convergent modulation of DMN functional connectivity. ObjectiveTo investigate the convergent remodeling characteristics of bidirectional effective connectivity （EC） of core DMN nodes with both the intra-network and the remaining whole-brain regions in CID patients with Yin-deficiency and fire-hyperactivity syndrome following the treatment with modified Suanzaoren Decoction or estazolam， so as to provide neuroimaging evidence for the convergent neural mechanisms underlying the therapeutic effects of both therapies in treating CID. MethodsEighty-two patients diagnosed with CID according to the International Classification of Sleep Disorder， third edition （ICSD-3） were consecutively recruited from the outpatient clinic of the Inner Mongolia Autonomous Region Mental Health Center from October 2020 to September 2023. Based on treatment preference， patients were assigned to receive a 6-week intervention in either the modified Suanzaoren Decoction group （n=52） or the estazolam group （n=30）. Ultimately， 66 patients completed follow-up assessments （modified Suanzaoren Decoction group， n=41； estazolam group， n=25）. All CID patients underwent resting-state functional magnetic resonance imaging scanning before and after treatment. Core DMN nodes including medial prefrontal cortex （mPFC）， bilateral inferior parietal lobule （IPL）， and precuneus （PCUN） were selected as seed regions. Granger causality analysis （GCA） was employed to assess bidirectional EC between the seed regions and both the other intra-DMN nodes and the remaining whole-brain regions. Hepatic and renal function indices were detected pre- and post-treatment to evaluate the safety profiles of both treatments. ResultsAt baseline， significant between-group differences were identified in EC from the left IPL to the left middle fronto-orbital gyrus/gyrus rectus （t=5.24， Z=4.84， voxel-level P<0.001， cluster-level P<0.05， GRF-corrected）， with the modified Suanzaoren Decoction group exhibiting stronger EC than the estazolam group. No significant between-group differences were observed in EC between other core DMN nodes and remaining whole-brain regions （P>0.05）. Within-group pre- to post-treatment comparisons demonstrated consistent connectivity alterations in both groups. Specifically， EC from the left IPL to the supplementary motor area （SMA） decreased after treatment （modified Suanzaoren Decoction group： t=-6.28， Z=5.208； estazolam group： t=-5.58， Z=4.425）. Conversely， EC from the SMA to the left IPL increased （modified Suanzaoren Decoction group： t=5.89， Z=4.968； estazolam group： t=6.15， Z=4.720）. Furthermore， both groups demonstrated reduced EC from the PCUN to the left IPL （modified Suanzaoren Decoction group： t=-5.85， Z=4.94； estazolam group： t=-5.75， Z=4.515）， and elevated EC from the left IPL to the PCUN （modified Suanzaoren Decoction group： t=5.29， Z=4.579； estazolam group： t=4.55， Z=3.826） （voxel-level P<0.001， cluster-level P<0.05， GRF-corrected）. No significant pre- to post-treatment differences were observed in hepatic or renal function indices in either group （P>0.05）. ConclusionIn CID patients with Yin-deficiency and fire-hyperactivity syndrome， both modified Suanzaoren Decoction and estazolam induce convergent bidirectional remodeling of EC between the left IPL and the SMA and the PCUN. ［Funded by Natural Science Fund Project of Inner Mongolia Autonomous Region （number， 2019MS08099）； ClinicalTrials.gov number， NCT06452953］

Methods: Data of the onset time and diagnostic types of STDs cases in Yangzhou City from 2019 to 2023 were collected from the Infectious Disease Surveillance System of Chinese Disease Prevention and Control Information System. The temporal, regional and population characteristics of five types of STDs was analyzed using the descriptive epidemiological method. Results: A total of 10 895 cases of STDs were reported in Yangzhou City from 2019 to 2023, with an average annual reported incidence rate of 47.83/105. The average annual reported incidence rates of syphilis, gonorrhea, condyloma acuminatum, genital herpes and genital Chlamydia trachomatis infections were 41.11/105, 2.83/105, 2.59/105, 0.43/105 and 0.85/105, respectively. The reported incidence rate of STDs showed a decreasing trend from 2019 to 2023 (P<0.05), with an average annual growth rate of -3.44%. The reported incidence rates of syphilis and gonorrhea showed a decreasing trend (both P<0.05), with average annual growth rates of -4.26% and -6.47%, respectively. The reported incidence rate of genital Chlamydia trachomatis infection showed an increasing trend (P<0.05), with an average annual growth rate of 22.32%. Baoying County, Guangling District and Hanjiang District had the top three reported incidence rates of STDs, at 56.61/105, 55.61/105 and 46.50/105, respectively. The average annual reported incidence rate of STDs among males was higher than that among females (53.19/105 vs. 42.54/105, P<0.05). The STD cases were primarily people aged 50 years and above, with 6 641 cases accounting for 60.95%. The occupations of STD cases were mainly farmers, housekeepers and unemployed, with 4 670 and 3 273 cases accounting for 42.86% and 30.04%, respectively. Conclusions The overall reported incidence of STDs in Yangzhou City from 2019 to 2023 showed a downward trend, while the reported incidence of genital Chlamydia trachomatis infection showed an upward trend. The individuals aged 50 years and above, farmers, housekeepers and the unemployed were identified as high-risk groups for STDs.

Objective To investigate the effects of high-altitude hypoxic environment on the pharmacokinetic characteristics and brain tissue distribution of phenytoin sodium in epileptic rats.Methods A total of 70 male SPF-grade Wistar rats aged 2 months and weighing(200±20)g were used in the study.An epilepsy model was induced in the rats using the lithium chloride-pilocarpine method.The successfully modeled rats were randomly assigned to a normoxic treatment group and a high-altitude hypoxic treatment group.Phenytoin sodium was administered via intragastric gavage at a dose of 50 mg/kg in both groups.Blood samples were collected from the orbital venous plexus before treatment and 0.5,1,2,3,4,6,8,10,and 24 h post treatment.The animals were euthanized after the final blood collection,and samples of the liver and the whole brain tissue were collected.In the brain tissue distribution experiment,brain tissue samples were collected at 0.5,1,2,and 4 h after drug administration.The concentration of phenytoin sodium in rat plasma and brain tissue was determined by liquid chromatography-tandem mass spectrometry(LC-MS/MS),and the pharmacokinetic parameters were calculated using WinNolin 8.1 software.The expression levels of CYP2C9 in liver tissue and those of P-gp in brain tissue of epileptic rats were determined by Western blot.Results Compared with those in the normoxia group,the peak concentration,peak time,and half-life of phenytoin sodium in the high-altitude hypoxia group were significantly decreased by 46.0%,42.3%,and 55.5%,respectively(all P<0.05);the clearance rate was significantly increased by 162.0%(P<0.05);and the area under the curve of plasma concentration-time curve was decreased by 45.6%(P<0.01).At 0.5,1,and 2 hours after administration,compared with that in the normoxia treatment group,the concentration of phenytoin sodium in the brain tissue of the high-altitude hypoxia treatment group was significantly decreased by 78.1%,63.5%,and 32.5%,respectively(all P<0.05).Western blot results showed that the expression levels of CYP2C9 in the liver tissue and P-gp in the brain tissue of rats in the high-altitude hypoxia group were approximately 1.78 and 1.65 times higher than those in the normoxia group,respectively(both P<0.05).Conclusion The hypoxic environment at high altitudes can promote the metabolism of phenytoin sodium,reduce its absorption efficiency,and change the characteristics its distribution in the brain,which may be related to the up-regulation of the expression of CYP2C9 in the liver and that of P-gp in the brain.

Currently, transcatheter intervention is the preferred treatment for patients with anatomically suitable atrial septal defects. However, the use of nickel-titanium alloy occluders in interventional procedures results in lifelong presence of the implant in the body, leading to complications such as metal allergies and arrhythmias in some patients. To overcome the short-term and long-term complications associated with the presence of metal, and to avoid radiation exposure and metal toxicity, this paper reports a case of successful transcatheter closure of atrial septal defect in a pediatric patient with metal allergies using fully biodegradable occluder under ultrasound guidance, achieving excellent results by interventional therapy.

Objective To investigate whether dexmedetomidine(DEX)can inhibit the inflammatory response mediated by microglia after traumatic brain injury(TBI)in rats through the cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon gene(cGAS-STING)pathway.Methods A TBI rat model was constructed,and successfully modeled rats were randomly separated into TBI group,low and high-dose dexmedetomidine treatment groups(DEX-L,DEX-H groups),and high-dose dexmedetomidine treatment+cGAS-STING pathway activator group(DEX-H+DMXAA group),with 18 rats in each group.Additionally,18 healthy normal rats were selected as the Control group.Rats in each group were subjected to neurobehavioral scoring(mNSS).The brain water content of rats in each group was detected.Flow cytometry was used to detect Tregs in the brain tissue of each group.ELISA was applied to detect the levels of inflammatory cytokines in brain tissue.HE staining was applied to observe brain tissue injury.TUNEL staining was applied to detect neuronal apoptosis.Immunohistochemistry was applied to detect the expression of the microglial cell marker ion calcium binding adapter molecule 1(Iba1).Western blot was applied to detect the expression of apoptosis and cGAS-STING pathway related proteins.Results Compared with the Control group,the TBI group showed structural injury to brain tissue,edema,abnormal neuronal morphology,reduced number and disordered arrangement,deep staining of nuclear folds,and blurred nucleoli,the mNSS score,brain tissue water content,levels of Tregs,TNF-α,IL-1 β,IL-6,neuronal apoptosis rate,expression of caspase-3,caspase-3,Iba1,cGAS,p-STING,p-TBK1,p-IRF3,IFN-Ⅰ were elevated(P＜0.05).Compared with the TBI group,the brain tissue structure of the DEX-L and DEX-H groups was slightly injuried,edema was reduced,and the morphology of neurons was relatively normal,with a small decrease in number and relatively neat arrangement,a small amount of nuclei were wrinkled and deeply stained,and most of the nucleoli were obvious,the mNSS score,brain tissue water content,levels of Tregs,TNF-α,IL-1β,IL-6,neuronal apoptosis rate,expression of caspase-3,caspase-3,Iba1,cGAS,p-STING,p-TBK1,p-IRF3,IFN-Ⅰ were reduced(P＜0.05).The brain tissue structure and neuronal injury in the DEX-H+DMXAA group were more severe than the DEX-H group,the mNSS score,brain tissue water content,levels of Tregs,TNF-α,IL-1β,IL-6,neuronal apoptosis rate,expression of caspase-3,caspase-3,Iba1,cGAS,p-STING,p-TBK1,p-IRF3,IFN-Ⅰ were elevated(P＜0.05).Conclusion Dexmedetomidine can inhibit the inflammatory response mediated by microglia after TBI in rats,and its mechanism of action is related to the inhibition of the cGAS-STING pathway.

Objective To analyze acupoint selection law of Professor Fu Wenbin in using acupuncture for the treatment of insomnia based on data mining technology;To provide references for the formulation and optimization of clinical treatment plans.Methods The cases of insomnia treated by acupuncture in the Acupuncture and Moxibustion Department of Guangdong Provincial Hospital of Traditional Chinese Medicine from January 1,2020 to December 31,2021 and in the Acupuncture and Moxibustion Department of Shenzhen Bao'an Hospital of Traditional Chinese Medicine from August 1,2018 to December 31,2021 were collected.A database of prescription information for acupuncture treatment for insomnia was established.The law of acupoint selection frequency,meridians,specific acupoints,correlation analysis and hidden structure analysis for acupuncture treatment of insomnia was mined.Results A total of 517 prescriptions were collected.Acupoints were mainly taken from Baihui(DU20,516 times),Yintang(DU29,499 times),Zhongwan(RN12,482 times)and Taichong(LR3,410 times),and meridians were mainly from Conception Vessel(2 120 times,11 acupoints),Governor Vessel(1 074 times,5 acupoints),liver meridian(410 times,1 acupoint),stomach meridian(401 times,8 acupoints)and kidney meridian(300 times,6 acupoints).The main specific acupoints were the Jiaohui(2 723 times,20 acupoints),Mu(892 times,4 acupoints),and Yuan(746 times,8 acupoints).The core acupoint combination based on Zhongwan-Baihui,Yintang(RN12-DU20-DU29)was formed by the correlation analysis of high-frequency acupoints,and the hidden structure of high-frequency acupoints was analyzed to obtain four comprehensive clustering models corresponding to the evidence of heart-kidney disharmony,liver depression and kidney deficiency,liver depression and kidney deficiency,and heart and gallbladder dysregulation.Conclusion Professor Fu Wenbin uses acupuncture to treat insomnia,with balancing yin and yang,regulating Conception Vessel and Conception Vessel as the basic treatment principle,dredging the liver to regulate the spirit,harmonizing the stomach to calm the spirit,communicating with the heart and kidney,and treating the heart and gallbladder as the treatment method.

Objective To investigate the effect of different radiotherapy doses on the prognosis of patients with stage cT1-4N0M0 esophageal squamous cell carcinoma(ESCC)who received radical radio(chemo)therapy categorized into subgroups with different tumor local factors.Methods A retrospective analysis was conducted on 256 patients with clinically nonmetastatic esophageal squamous cell carcinoma.The optimal cutoff for tumor local factors was determined.The relationship between latest treatment efficacy and tumor local factors was analyzed,and independent indicators affecting patient overall survival(OS)were examined using multivariate analysis.The subgroup analysis was performed to determine the correlation between selected factors and radiation therapy doses.Results The shorter the X-ray length of esophageal tumor lesion and the smaller the lesion canal wall thickness and gross tumor volume(GTV),the better the latest treatment efficacy of the patients(χ2=9.066,10.310,15.661,respectively,P=0.011,0.006,P＜0.001).Multivariate analysis results showed that GTV(P＜0.001),radiation dose(P=0.038),and latest treatment efficacy(P＜0.001)were independent predictors of the patients'OS,and the latter two were also independent predictors of the patients'progression-free survival(PFS)(P=0.033,＜0.001).Subgroup analysis further showed that high doses of radiotherapy(over 60 Gy)resulted in good OS(χ2=5.040,4.588,5.400,P=0.025,0.032,0.020)and PFS(χ2=6.089,4.353,6.459,P=0.014,0.037,0.011)in the subgroup with maximum wall thickness below 3.7 cm,with esophageal lesions with GTV below 37.34 cm3,or not receiving simultaneous chemotherapy.Conclusion Local tumor factors are important prognostic factors of ESCC patients treated with radical radio(chemo)therapy.Patients with thin lesion walls and small tumor volumes may greatly benefit from high doses of radiation(over 60 Gy).
