Objective: To investigate how Zuogui Jiangtang Qingzhi Formula (ZGJTQZF), a traditional Chinese medicine compound for lowering blood glucose levels and clearing lipids based on Zuogui Pill, regulates the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING)/TANK-binding kinase 1 (TBK1) signaling pathway to improve type 2 diabetes mellitus combined with non-alcoholic fatty liver disease. Methods: According to fasting blood glucose (FBG) levels, body weight, and sex, 40 MKR mice, with half being male and the other half female, were randomly divided into four groups: blank, model, ZGJTQZF (29.6 g/kg), metformin + simvastatin ([65.0+ 2.6] mg/kg), 10 mice per group, and a normal group consisting of 10 age-matched FVB mice. Mice in all groups, except in the normal and blank groups, were fed a high-fat diet for 8 weeks to induce the disease model. Each group received daily gavage of the respective treatments for 8 weeks after successful modeling. Various parameters were measured, including FBG, liver function (alanine aminotransferase [ALT] and aspartate transaminase [AST]), and blood lipids (triglyceride [TG] and total cholesterol [TC]). Serum levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were determined using enzyme-linked immunosorbent assays. Histological liver changes were examined using transmission electron and optical microscope. cGAS, STING, and TBK1 protein and mRNA expression levels in liver tissues were detected using Western blotting and real-time PCR, respectively. Results: Compared with the normal group, the model group exhibited significant fat accumulation in hepatocytes and liver damage. Additionally, FBG, ALT, AST, serum TNF-α, IL-6, cGAS, STING and TBK1 expression levels in liver tissues were significantly elevated (P<0.05). Treatment with ZGJTQZF and metformin + simvastatin significantly improved FBG, ALT, AST, TG, TC, TNF-α, and IL-6 (P<0.01). Histologically, hepatic steatosis was notably alleviated. Expression of protein and mRNA of cGAS, STING, and TBK1 in liver tissues was significantly reduced (P<0.05). Conclusion ZGJTQZF improves lipid and glucose metabolism, mitigates liver injury, and reduces inflammatory markers in MKR mice. These effects may be mediated through the regulation of the cGAS/STING/TBK1 signaling pathway.

This paper presents an automatic acquisition and analytic procedure of acupuncture manipulation based on optical navigation, aiming at solving the shortcomings of existing acquisition methods of acupuncture manipulation. An acquisition holder installed at the handle tail of filiform needle was designed to display the movement trajectory of the needle during acupuncture delivery by collecting the movement trajectory of holder. The 3-month old male Bama miniature pig was selected as the experimental subject, and 6 points, "Bojian" "Qiangfeng" "Housanli" "Xiaokua" "Huiyang" (BL35) and "Baihui" (GV20), were selected during acupuncture manipulation. The optical navigation system was used to collect the real-time data, and these data were per-processed and analyzed using mean filtering and Fourier transform. The acupuncture procedure was divided into 3 stages, inserting, lifting-thrusting, and twisting. The results showed that the accuracy was 96.3% at lifting-thrusting stage, and that was 100.0% at twisting stage. The decomposition effect of the entire procedure was satisfactory. This study provides a new approach to the quantitative analysis of acupuncture manipulation. In the future, it needs to further optimize the algorithm and expand the sample size so as to improve the accuracy of this analytic technique.

Objective To explore the clinical efficacy of recombinant human prourokinase during emergency coronary intervention (PCI) in patients with acute inferior wall ST segment elevation myocardial infarction (STEMI) without reflow or slow blood flow.Methods Eighty patients with acute inferior wall STEMI admitted to Xinyi People's Hospital from January 2022 to December 2023 were selected.The patients were divided into two groups,40 cases in each group.The control group patients accepted PCI after receiving 100μg nitroglycerin or nitroprusside via catheter;On the basis of control group,the observation group patients received 20mg recombinant human prourokinase via catheter until infarct related artery,and PCI was performed.Using thrombolysis in myocardial infarction (TIMI) blood flow grading method,compared the immediate myocardial perfusion after surgery.Results Comparison of immediate TIMI blood flow grading between two groups of patients during surgery,with grades ranging from level 0 to 1:1 case (2.5％) in observation group and 7 cases (17.5％) in control group.The difference between two groups was statistically significant (P<0.05);Level 2:3 cases (7.5％) in observation group and 8 cases (20.0％) in control group.There was no statistically significant difference between two groups (P>0.05);Level 3:36 cases (90.0％) in observation group and 25 cases (62.5％) in control group.The difference between two groups was statistically significant (P<0.05).Conclusion Recombinant human prourokinase can effectively improve the coronary blood flow of infarct related artery during emergency PCI in patients with acute inferior wall STEMI,improve myocardial ischemia,and do not increase adverse reactions such as bleeding,which is of great significance for improving patient's prognosis.

Purpose To explore the value of ultrasonography in distinguishing periductal mastitis(PDM)from granulomatous lobular mastitis(GLM)and summarize the sonographic features of non-puerperal mastitis(NPM).Materials and Methods The ultrasonographic findings of 134 NPM(84 PDM,50 GLM)patients treated in the Second Hospital of Lanzhou University from July 2016 to June 2021 were retrospectively analyzed.Comparing PDM and GLM sonograms,the difference of lesion number,lesion side,lesion orientation,distance from the nipple,long diameter,thick diameter,aspect ratio,boundary,edge,edge,shape,internal echo,peripheral high echo halo,rear echo,calcification,internal blood flow,ipsilateral axillary lymph node enlargement,and summarize the characteristics of NPM according to the lesion morphology and internal echo.Results There was no statistical difference between PDM and GLM(P＞0.05).But the probability of PDM combined with ipsilateral axillary lymph node enlargement was slightly higher than that of GLM(x2=4.209,P=0.040).The ultrasonography of 134 cases of NPM lesions was divided into 7 types according to the morphology and echo changes.The abscess type was more common in GLM than in PDM(x2=4.928,P=0.026).Conclusion There is no significant difference between PDM and GLM.In the case that PDM and GLM cannot be distinguished clinically and radiologically,it is recommended to perform puncture biopsy to determine the pathological type before treatment,which may be more conducive to obtaining the best prognosis for patients.In addition,the classification of NPM into 7 types is helpful for sonographers to grasp the ultrasonographic characteristics of NPM to diagnose NPM early.

Objective:To estimate the influence of metabolic parameters in 18F-FDG PET/CT and clinically relevant indicators on the prognosis of patients with cervical cancer. Methods:A total of 174 patients with cervical cancer (age (53.6±11.1) years) who underwent baseline 18F-FDG PET/CT examination in the Affiliated Hospital of Qingdao University from May 2011 to December 2020 were retrospectively collected. Metabolic parameters (metabolic tumor volume of primary lesion (MTV p), total lesion glycolysis of primary lesion (TLG p), MTV sum of total lesions (MTV total) in the whole body, TLG sum of total lesions (TLG total)) and clinical parameters (International Federation of Gynecology and Obstetrics (FIGO) stage, tumor maximum diameter ( Dmax), et al) were collected. Cox regression and Kaplan-Meier method were performed to evaluate the prognostic and predictive values of those parameters. Results:The follow-up time was 6-120 months, during which 52 patients (29.9%, 52/174) developed progression. The 5-year overall survival (OS), progression-free survival (PFS), local control (LC) and distant metastasis-free survival (DMFS) rates were 83.3%(145/174), 70.1%(122/174), 75.3%(131/174) and 82.8%(144/174), respectively. Cox regression showed that FIGO stage and MTV total were independent factors for predicting PFS, OS and LC (hazard ratio ( HR): 1.005-11.605, all P<0.05). FIGO stage and TLG total were independent factors for predicting DMFS ( HR: 1.002-12.258, all P<0.05). Conclusion:MTV total and FIGO stage are effective predictors of patients with cervical squamous cell carcinoma.

Objective To investigate the impact of Atractylodin on lung tissue damage in young asthmatic rats by regulating the CXC chemokine ligand 12(CXCL12)/CXC chemokine receptor 4(CXCR4)signaling pathway.Methods Twelve young SD rats were randomly selected from 60 rats as the control group(CON group),while the remaining 48 rats were used to construct asthma models using ovalbumin(OVA).Successfully modeled asthma rats were randomly separated into Model group,Atractylodin group(50 mg/kg Atractylodin),and CXCL-12 group(5 μ g/kg recombinant CXCL-12 protein)and Atractylodin+CXCL-12 group(50 mg/kg Atractylodin+5 μ g/kg recombinant CXCL-12 protein),with 12 in each group,continuously administered for 14 days.The CON and Model groups were given equal amounts of physiological saline.The percentages of neutrophils and eosinophils in bron-choalveolar lavage fluid(BALF)were detected.ELISA method was applied to detect cytokine levels in serum and BALF fluid;HE staining was applied to detect pathological changes in lung tissue;Western blot was applied to detect the levels of CXCL12/CXCR4 pathway related proteins.Results Compared with the CON group,the pathological score of lung tissue,percentage of neutrophils,percentage of eosinophils,the levels of IL-17,IL-4,IL-5,IL-13,IgE,OVA sIgE,and the protein levels of CXCL12 and CXCR4 in Model group were obviously increased(P<0.05);compared with the Model group,the pathological score of lung tissue,percentage of neutro-phils,percentage of eosinophils,the levels of IL-17,IL-4,IL-5,IL-13,IgE,OVA sIgE,and the protein levels of CXCL12 and CXCR4 in the Atractylodin group were obviously reduced(P<0.05),the results in the CXCL-12 group were opposite to those in the Atractylodes group;CXCL-12 eliminated the improvement effect of atractylodes on asthma rats.Conclusion Atractylodin may improve lung tissue damage in asthmatic rats by down-regulating the CXCL12/CXCR4 signaling pathway.
