Objective To explore the effects of Shuanglu Tongnao Formula on neuroinflammation in ischemic stroke (IS) rats via the P2X purinoceptor 7 receptor (P2X7R)/NLR family pyrin domain-containing 3 (NLRP3) pathway. Methods The rats were divided into five groups: the IS group, control group, Shuanglu Tongnao Formula group, P2X7R inhibitor brilliant blue G (BBG) group, and Shuanglu Tongnao Formula combined with P2X7R activator adenosine triphosphate (ATP) group, with 18 rats in each group. Except for the control group, rats in all other groups were used to construct an IS model using the suture method. After successful modeling, the drug was given once a day for 2 weeks. Neurological function scores and cerebral infarction volume ratios were measured in rats. Pathological examination of the ischemic penumbra brain tissue was performed. Immunofluorescence staining was used to quantify the proportions of microglia co-expressing both inducible nitric oxide synthase (iNOS) and ionized calcium-binding adapter molecule 1 (Iba1), as well as arginase 1 (Arg1) and Iba1, in the ischemic penumbra brain tissue. ELISA was used to detect tumor necrosis factor-alpha (TNF-α), transforming growth factor-beta (TGF-β), interleukin 6 (IL-6) and IL-10 in the ischemic penumbra brain tissue. Western blotting was used to measure P2X7R, NLRP3, and IL-1β proteins in the ischemic penumbra brain tissue. Results Compared with the control group, the IS group showed disordered neuronal arrangement, nuclear condensation, and obvious infiltration of inflammatory cells in the ischemic penumbra; significantly elevated neurological function scores, cerebral infarction volume ratios, proportions of microglia co-expressing iNOS and Iba1, and levels of TNF-α, IL-6, and P2X7R, NLRP3, IL-1β proteins; along with reduced proportions of microglia co-expressing Arg1 and Iba1 and levels of TGF-β and IL-10. Compared with the IS group, the Zhuang medicine Shuanglu Tongnao Formula and BBG groups demonstrated alleviated brain tissue damage; reduced neurological function scores, cerebral infarction volume ratios, proportions of microglia co-expressing iNOS and Iba1, and levels of TNF-α, IL-6, and P2X7R, NLRP3, IL-1β proteins; along with increased proportions of microglia co-expressing Arg1 and Iba1 and levels of TGF-β and IL-10. ATP reversed the effects of Zhuang medicine Shuanglu Tongnao Formula on microglial polarization and neuroinflammation in IS rats. Conclusion Zhuang medicine Shuanglu Tongnao Formula may promote the transformation of microglia from M1 type to M2 type by inhibiting the P2X7R/NLRP3 pathway, thereby improving neuroinflammation in IS rats.

Metformin has been demonstrated to attenuate hyperglycaemia by modulating the gut microbiota. However, the mechanisms through which the microbiome mediates metformin monotherapy failure (MMF) are unclear. Herein, in a prospective clinical cohort study of newly diagnosed type 2 diabetes mellitus (T2DM) patients treated with metformin monotherapy, metagenomic sequencing of faecal samples revealed that Phocaeicola vulgatus abundance was approximately 12 times higher in nonresponders than in responders. P. vulgatus rapidly hydrolysed taurine-conjugated bile acids, leading to ceramide accumulation and reversing the improvements in glucose intolerance conferred by metformin in high-fat diet-fed mice. Interestingly, C22:0 ceramide bound to mitochondrial fission factor to induce mitochondrial fragmentation and impair hepatic oxidative phosphorylation in P. vulgatus-colonized hyperglycaemic mice, which could be exacerbated by metformin. This work suggests that metformin may be unsuitable for P. vulgatus-rich T2DM patients and that clinicians should be aware of metformin toxicity to mitochondria. Suppressing P. vulgatus growth with cefaclor or improving mitochondrial function using adenosylcobalamin may represent simple, safe, effective therapeutic strategies for addressing MMF.

Objective:To analyze the immediate risk and 5-year cumulative risk of high-grade cervical lesions in high-risk human papillomavirus(Hr-HPV)positive patients with minor cytological abnormalities and to validate the local applicability of clinical management strategies in the 2019 American Society for Colposcopy and Cervical Pathology Guidelines.Methods:A total of 565 patients with positive Hr-HPV,cytology result of atypical squamous cells of undetermined significance(ASC-US)or low-grade squamous intraepithelial lesion(LSIL)and also under-went colposcopy and biopsy were selected from the gynecological clinic of Peking Union Medical College Hospital from February 2017 to November to analyze the immediate risk of high-grade cervical lesions(CIN2 and above).Besides,a total of 193 patients with histological results of CIN1 or below and 5-year follow-up data available were further analyzed for the 5-year cumulative risk of high-grade cervical lesions.Results:①In the 565 patients,the immediate incidence of CIN2+and CIN3+was 32.21%and 12.39%,respectively.Multivariate Logistic regression showed that the immediate risk of CIN2+in the LSIL group(35.54%)was 1.62 times that in the ASC-US group(28.78%)(95%CI 1.12-2.36,P＜0.05);the immediate risk of CIN2+in HPV 16/18+group(45.29%)was 2.89 times that in Hr-HPV other+group(23.68%)(95%CI 1.99-4.20,P＜0.05).② Among 193 patients with 5-year long-term follow-up,the 5-year cumulative incidence of CIN2+and CIN3+was 6.2%and 2.6%,respectively.Cox regression analysis results showed that there were no statistically significant differences in 5-year cumulative risk of CIN2+and CIN3+among different ages,Hr-HPV infection types and cytological results(P＞0.05).Conclu-sions:LSIL had a higher detection rate of CIN2+than ASC-US patients only in the first colposcopy biopsy;the immediate risk of high-grade cervical lesion was significantly higher in HPV16/18+patients than in Hr-HPV oth-er+patients,but no significant difference in the 5-year cumulative incidence of high-grade lesions after colposco-py was found.Age was not an independent risk factor for the development of high-grade lesions.

This article systematically studied the moxibustion methods embedded in the 15 medical books of the Mawangdui medical literature. Starting from the origin of the medical moxibustion culture in Mawangdui， this paper comprehensively analyzed the records of moxibustion. By analyzing the Classic of Moxibustion to Eleven Foot-arm Channels （《足臂十一脉灸经》） and Classic of Moxibustion to Eleven Yin-yang Channels （《阴阳十一脉灸经》） as well as Formulas for Fifty-two Diseases （《五十二病方》）， which have relatively rich records of moxibustion， it is found that moxibustion involves more than 170 diseases and syndromes， covering 12 categories such as limb diseases related to meridians and collaterals， lung system diseases， and heart and brain diseases. In summary， the distinctive characte-ristics of moxibustion in Mawangdui medical books include primitive simplicity， combination of witch culture and medical practices， philosophical deduction， centripetal circulation， diverse moxibustion materials， extensive cove-rage of diseases and syndromes， taboos in moxibustion， and the integration of prevention and treatment. The ideas and applications of moxibustion mainly manifest in preventing diseases before they occur and preventing changes in existing diseases， distinguishing and treating each disease based on different causes， and combining treatment based on meridians， collaterals and comprehensive diseases.

Objective:A genome-wide molecular characterization of FJ21351116, a strain of G3P[8]-E2 2021 collected in Fujian, China, was performed.Methods:Whole genome sequencing of FJ21351116 was performed using a high-sensitivity group A rotavirus whole genome sequencing method. Genomic characteriza-tion of the virus was assessed by nucleic acid sequence analysis using MEGA 11.0, Geneious 9.0.2 and DNASTAR software. Neutralization epitopes of VP7 and VP4 (VP8*) were analyzed using BioEdit v. 7.0.9.0 and PyMOL v. 2.5.2.Results:In this study, FJ21351116 was shown to be a G3-P[8]-I2-R2-C2-M2-A2-N2-T2-E2-H2 genotype, and the result of phylogenetic tree showed that the VP7, VP4, VP3, and NSP2-NSP5 genes of the FJ21351116 strain were related to the equine-like DS-1-like G3P[8] genes that have been detected in Japan in recent years. VP6, VP1, VP2, and NSP1 genes are closely related to G2P[4] in most countries, especially in Singapore, suggesting that this strain was formed by genetic reassortment during the evolution of equine-like G3P[8] and G2P[4]. Evolutionary relationships between the VP7/VP4 genes of FJ21351116 and Rotarix and RotaTeq vaccines suggest that the multiple mutations in both VP7 and VP4 (VP8*) neutralizing antigenic epitopes and vaccine amino acid sites. It is hypothesized that the Rotarix and RotaTeq vaccines may be less effective against equine DS-1-like G3P[8] RVA, and the sequence differences with Rotarix are higher than those with RotaTeq.Conclusions:In this study, we found a rare case of DS-1-like G3P [8] RVA strain in China. Currently, horse-like DS-1-like G3P [8] RVA is relatively rare in China and may be poorly protected by vaccine strains, emphasizing the importance of continuous monitoring of RVA strains and the development of efficient and full-coverage RVA vaccines.

Objective:To understand the medical care of patients with sporadic Creutzfeldt-Jakob disease in China and its relationship with survival time.Methods:A retrospective analysis was performed on data of 150 patients with sporadic Creutzfeldt-Jakob disease diagnosed by China′s Creutzfeldt-Jakob Disease Surveillance Network during the period of January 1, 2021 to December 31, 2022 in this study, and telephone follow-up with family members was used to obtain information of the patients′ care, treatment, and survival after diagnosis. Survival was estimated by life table method, median survival time and 95% confidence interval ( CI) were calculated by Kaplan-Meier method, log-rank method was used to compare the difference in survival time between different groups, and multifactorial analysis was performed by COX proportional risk regression model regarding the influencing factors on patients′ survival time. Results:The median survival time of 150 patients with sporadic Creutzfeldt-Jakob disease was 6 months, and the cumulative lifetime survival rates at 2, 6, 12, and 18 months were 62%, 39%, 22%, and 9%, respectively. The result of univariate analysis showed that the differences in survival time between groups with the presence or absence of cortical blindness in the first symptom, the presence or absence of respiratory support (oxygen therapy), the presence or absence of adjunctive medication, and the presence or absence of tube feeding (nasogastric) were meaningful ( P<0.1). Multifactorial COX regression analysis showed that the risk of death in patients without adjuvant medication was 1.429 times higher than that in patients with adjuvant medication (95.0% CI: 1.014-2.014), and the risk of death in patients without tube feeding (nasal feeding) was 1.479 times higher than that in patients with tube feeding (nasal feeding) (95% CI: 1.052-2.081). Conclusions:Whether or not adjuvant medication is administered and whether or not tube feeding (nasogastric) is used are factors that affect survival time in patients with sporadic Creutzfeldt-Jakob disease, and the administration of appropriate adjuvant medication and tube feeding (nasogastric) may contribute to prolonging survival time in patients with sporadic Creutzfeldt-Jakob disease.

We report a case of a young female patient with fatigue, hypokalemia, and hyperglycemia. She had past-history of diabetes mellitus, and was admitted to hospital with a history of fatigue and hypokalemia for 5 years. The patient's examination indicated hypokalemia, hypomagnesemia, metabolic alkalosis, hypocalciuria, and SLC12A3 gene pathogenic mutation. The diagnosis was Gitelman syndrome. Potassium and magnesium supplements were given to improve the patient's fatigue. Serum potassium and magnesium were normal. The blood glucose reached standard after treatment with oral hypoglycemic drugs. This article incorporates literature review to sort out the diagnosis and treatment of Gitelman syndrome, in order to provide feasible reference for clinicians.
