OBJECTIVE: To observe the effects of point-moxibustion with Zhuang medicinal thread on differentially expressed genes (DEGs) in the dorsal root ganglion (DRG), tissue morphology, and the expression of Fc epsilon RI (FcεRI) pathway proteins spleen tyrosine kinase (Syk) and membrane spanning 4-domain A2 (MS4A2) in rat model of postherpetic neuralgia (PHN), and to explore the potential mechanism by which this therapy alleviates pain sensitization. METHODS: Thirty-nine male Sprague-Dawley (SD) rats were randomly divided into a control group, a model group, and a moxibustion group, with 13 rats in each group. The PHN model was established in the model and moxibustion groups by intraperitoneal injection of resiniferatoxin. In the moxibustion group, bilateral L₄-L₆ "Jiaji" (EX-B2) points were treated with point-moxibustion with Zhuang medicinal thread from day 7 post-modeling, with two cones per acupoint per session, every other day for a total of 10 sessions. Mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) were measured at 1 day before modeling and on days 1, 4, 7, 13, 19, and 25 after modeling. After intervention, HE staining was used to observe DRG morphology. RNA sequencing was performed to analyze DEGs in DRG and conduct bioinformatics analysis. The expression of Syk and MS4A2 mRNA and proteins in the FcεRI pathway in DRG was detected by quantitative PCR and Western blot. RESULTS: Compared with the control group, the model group exhibited decreased MWT (P<0.05) and increased TWL (P<0.05); histopathological analysis revealed neuronal atrophy, nuclear displacement, and intracellular vacuoles, with a slightly loose arrangement; the RNA-Seq identified 3,207 DEGs (1,997 upregulated and 1,210 downregulated); the mRNA and protein expression levels of Syk and MS4A2 were significantly increased (P<0.01). Compared with the model group, the moxibustion group showed increased MWT (P<0.05) and decreased TWL (P<0.05), with relatively normal neuronal morphology; the RNA-Seq identified 426 DEGs (250 upregulated and 176 downregulated); the mRNA and protein expression levels of Syk and MS4A2 were significantly decreased (P<0.05). Venn diagram analysis identified 156 DEGs that showed a reversal in expression trends after treatment, including Syk and MS4A2, which are associated with pain sensitization. KEGG pathway analysis indicated that these DEGs were primarily enriched in the FcεRI pathway. CONCLUSION Point-moxibustion with Zhuang medicinal thread could alleviate pain sensitization in PHN rats, possibly by inhibiting the FcεRI signaling pathway and downregulating the expression of Syk and MS4A2.

ObjectiveTo investigate the association of SH2B1 rs7359397 （C>T） polymorphism with the progression to hepatic fibrosis in the elderly patients with metabolic dysfunction-associated steatotic liver disease （MASLD） in Beijing， China， and to provide an important genetic basis for the precise subtyping， prognostic evaluation， and individualized treatment of elderly MASLD patients in China. MethodsA total of 505 elderly patients （aged ≥65 years） who participated in regular physical examination in Mentougou Kuangshan Hospital of Beijing Jingmei Group General Hospital from November 2020 to September 2021 and were diagnosed with MASLD by abdominal ultrasound were enrolled as MASLD group， and 381 elderly population who underwent physical examination in the same community hospital during the same period of time and were not found to have MASLD by abdominal ultrasound were enrolled as control group. FibroScan was used to measure liver fat content and determine fibrosis stage. The 96-well microfluidic chip technique was used to identify SH2B1 rs7359397 polymorphism. The independent-samples t test was used for comparison of normally distributed continuous data between the two groups， and the chi-square test or the adjusted chi-square test was used for comparison of categorical data between the two groups. Univariate and multivariate Logistic regression analyses were used to identify the independent predictive factors for MASLD and its comorbidities. ResultsCompared with the control group， the MASLD group had a significantly younger age and significantly higher levels of waist circumference， hip circumference， waist-hip ratio， body mass index （BMI）， alanine aminotransferase， aspartate aminotransferase， triglyceride， platelet count， and fibrosis-4 （FIB-4） index， as well as a significantly lower level of high-density lipoprotein cholesterol （all P<0.05）. Among the 381 patients in the control group， 264 （69.29%） had genotype CC and 117 （30.71%） had genotype CT+TT， while among the 505 patients in the MASLD group， 317 （62.77%） had genotype CC and 188 （37.23%） had genotype CT+TT， suggesting that the MASLD group had a significantly higher proportion of patients with genotype CT+TT compared with the control group （χ²=4.09， P=0.043）. In the MASLD group， compared with the genotype CC group， the genotype CT+TT group had a significantly lower proportion of patients with FIB-4 ≥2 or atherosclerotic cardiovascular diseases （P<0.05）. The multivariate Logistic regression analysis showed that after adjustment for age， sex， and BMI， carrying T allele was a protective factor against progressive hepatic fibrosis （odds ratio ［OR］=0.481， 95% confidence interval ［CI］： 0.249 — 0.929， P=0.029）. In the subgroups of comorbidities with hypertension， metabolic syndrome， and obesity， genotype CT+TT was associated with a significant reduction in the risk of progressive hepatic fibrosis （hypertension： OR=0.27， 95%CI：0.09 — 0.77， P=0.014； metabolic syndrome： OR=0.30， 95%CI： 0.11 — 0.79， P=0.015； obesity： OR=0.11， 95%CI： 0.03 — 0.48， P=0.003）. After adjustment for age， sex， and BMI， in the patients with MASLD， the patients with genotype CT+TT had a significant reduction in the prevalence rate of atherosclerotic cardiovascular diseases compared with those with genotype CC （OR=0.506， 95%CI：0.336 — 0.761， P=0.001）. ConclusionSH2B1 rs7359397 （C>T） polymorphism is associated with the reduction in the risk of hepatic fibrosis and atherosclerotic cardiovascular diseases in MASLD patients.

The occurrence of benign prostate hyperplasia(BPH)was related to disrupted sex steroid hormones,and metformin(Met)had a clinical response to sex steroid hormone-related gynaecological disease.How-ever,whether Met exerts an antiproliferative effect on BPH via sex steroid hormones remains unclear.Here,our clinical study showed that along with prostatic epithelial cell(PEC)proliferation,sex steroid hormones were dysregulated in the serum and prostate of BPH patients.As the major contributor to dysregulated sex steroid hormones,elevated dihydrotestosterone(DHT)had a significant positive rela-tionship with the clinical characteristics of BPH patients.Activation of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK)by Met restored dysregulated sex steroid hormone homeostasis and exerted antiproliferative effects against DHT-induced proliferation by inhibiting the formation of androgen receptor(AR)-mediated Yes-associated protein(YAP1)-TEA domain transcription factor(TEAD4)heterodimers.Met's anti-proliferative effects were blocked by AMPK inhibitor or YAP1 over-expression in DHT-cultured BPH-1 cells.Our findings indicated that Met would be a promising clinical therapeutic approach for BPH by inhibiting dysregulated steroid hormone-induced PEC proliferation.

ObjectiveTo observe the effect of the combination of total saponin of Astragali Radix-total alkaloids of Nelumbinis Folium on reversal cholesterol transport （RCT） in hyperlipidemia rats， and to discuss its mechanism. MethodSixty SD rats were randomly divided into control group， high-fat diet group， total saponin of Astragali Radix-total alkaloids of Nelumbinis Folium low （17 mg·kg^-1+40 mg·kg^-1）， middle （34 mg·kg^-1+80 mg·kg^-1）， high dose （68 mg·kg^-1+160 mg·kg^-1） groups and simvastatin （2.1 mg·kg^-1） group， with 10 mice in each group. The Hyperlipidemia model was duplicated by feeding rats with a high-fat diet for 6 weeks. From the 3rd week， except for the control group and the high-fat diet group given distilled water， other groups were given corresponding drugs intragastric treatment for 4 weeks. The changes in blood lipid and liver function of rats were detected by an automatic biochemical analyzer. Hematoxylin-eosin （HE） and oil red O staining were used to observe the pathological morphological changes and steatosis of rat liver tissue. The contents of total cholesterol （TC） and total bile acid （TBA） in rat liver tissue and feces were determined by a semi-automatic biochemical analyzer. The mRNA and protein expression levels of peroxisome proliferators-activated receptors γ （PPARγ）， liver X receptors α （LXRα）， ATP-binding cassette transporter G1 （ABCG1） and cholesterol 7α-hydroxylase （CYP7A1） in rat liver tissue were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultCompared with the control group， the contents or activities of TC， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C）， TBA， aspartate aminotransferase （AST）， alanine aminotransferase （ALT） in serum were significantly increased （P<0.01）， and the contents of high-density lipoprotein cholesterol （HDL-C） in the high-fat diet group were significantly decreased （P<0.01）. The hepatocyte was clearly swollen like ballooning degeneration， with a lot of fat vacuoles and red fat droplets. The contents of TC and TBA in liver tissue and feces were significantly increased （P<0.01）， and the mRNA and protein expression levels of PPARγ， LXRα， ABCG1， and CYP7A1 in liver tissue were significantly decreased （P<0.01）. Compared with the high-fat diet group， the contents or activities of TC， TG， LDL-C， TBA， AST， and ALT in the serum of rats in administered groups were significantly decreased （P<0.01）， while the content of HDL-C was significantly increased （P<0.01）. Hepatocyte swelling was significantly reduced， and the ballooning degeneration， fat vacuoles， and red lipid droplets in liver tissue were significantly decreased. The contents of TC and TBA in liver tissue were significantly decreased （P<0.05， P<0.01）， and the contents of TC and TBA in feces were significantly increased （P<0.05， P<0.01）. The mRNA and protein expression levels of PPARγ， LXRα， ABCG1， and CYP7A1 in liver tissue were significantly increased （P<0.05， P<0.01）. ConclusionTotal saponin of Astragali Radix-total alkaloids of Nelumbinis Folium has a positive effect on the prevention and treatment of hyperlipidemia rats， and its mechanism may be related to the activation of PPARγ/LXRα/ABCG1 signaling pathway and regulation of RCT.

Objective It compared the power consumption and electrical parameters between Thulium fiber laser devices(TFL)and Holmium laser devices(HoL)in transurethral enucleation of prostate(TUEP).Methods A sin-gle surgeon conducted TUEP by THL or HoL in 10 patients respectively.The enucleation efficiency,the laser energy output and the electric parameters were recorded and analyzed.Results The data from both groups of surgeries were tested for normal distribution,and the t-test found that the difference in the enucleation efficiency between the two surgeries was not statistically significant(P=0.818),and the energy consumption indexes of the two devices were comparable.The difference in the total kilojoules of laser emission between the two lasers during surgery was not statistically significant(P=0.148),but the power consumption of the thulium laser was about one-tenth of that of the holmium laser(P＜0.001),suggesting that the former utilised electrical energy significantly more efficiently than the latter.The maximum current of the HoL was significantly higher than that of the TFL(P＜0.001),requiring a spe-cial high-power power outlet.Conclusion TFL was superior to HoL in terms of lower power consumption,higher en-ergy-efficient and electrical convenient in transurethral enucleation of the prostate.
