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.

The clinical data of a patient with differentiated thyroid carcinoma(DTC)who developed physiological thymic uptake after postoperative iodine-131(131I)therapy were analyzed,and the 3-year follow-up changes in the patient's condition were reviewed.Combined with the literatures and the diagnosis and treatment process,the causes of possible false positives in whole-body scans after iodine therapy for DTC and the mechanism,clinical features,and identification methods of benign thymic 131I uptake were discussed to improve clinicians' understanding and diagnostic ability regarding such conditions and avoid unnecessary multiple iodine treatments.The patient,a 28-year-old female,showed mediastinal imaging after the first 131I treatment,with more pronounced mediastinal iodine uptake during the second treatment.SPECT/CT localized the uptake to enlarged thymus tissue.The stimulated thyroglobulin(Tg)levels before two 131I treatments were high but gradually decreased.Apart from thymic uptake,no other examination evidence suggested DTC metastases.Subsequent follow-up for 3 years showed no pathological changes in the thymus,confirming physiological thymic uptake.Thymic 131I uptake is a common cause of false-positive whole-body scans in post-thyroidectomy patients.When post-131I therapy whole-body imaging shows only mediastinal uptake,especially in the young patients undergoing multiple 131I treatments where thymic 131I uptake intensity increases with successive treatments,even with elevated Tg levels,comprehensive use of imaging results such as SPECT/CT is essential to determine if it is normal thymus,thereby avoiding unnecessary repeated therapies.

Objective To explore the effect of nimodipine combined with minimally invasive puncture on neurological function,hemodynamics,and serum inflammatory factor levels in patients with hypertensive intracerebral hemorrhage(HICH).Methods A total of 108 patients with HICH treated at the Second Affiliated Hospital of Hebei North University from June 2019 to May 2022 were selected as the research subjects.They were divided into an observation group(n=55)and a control group(n=53)according to the treatment method.All patients in the two groups received minimally invasive puncture;on this basis,the patients in the observation group were treated with nimodipine for one month.The neurological deficit of patients in the two groups was evaluated by the National Institute of Health Stroke Scale(NIHSS)score before and after treatment.Before and after treatment,5 mL of fasting venous blood was taken from patients in the morning,and the serum was obtained by centrifugation.The serum levels of brain-derived neurotrophic factor(BDNF),neuron-specific enolase(NSE),C-reactive protein(CRP),tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)were detected by enzyme-linked immunosorbent assay.Ultrasonic transcranial Doppler blood flow analyzer was used to monitor the hemodynamic indexes such as mean blood flow velocity(Vm),resistance index(RI)and pulsitility index(PI)of patients in the two groups before and after treatment.The adverse reactions such as headache,dizziness,infection and rebleeding were recorded in the two groups after treatment.Results There was no statistically significant difference in the NIHSS score and serum NSE and BDNF levels between the two groups before treatment(P＞0.05).After treatment,the NIHSS score and serum NSE level of patients in the two groups were significantly lower than those before treatment,while the serum BDNF level was significantly higher than that before treatment(P＜0.05).After treatment,the NIHSS score and serum NSE level of patients in the observation group were significantly lower than those in the control group,while the serum BDNF level was significantly higher than that in the control group(P＜0.05).There was no statistically significant difference in the Vm,PI and RI between the two groups before treatment(P＞0.05).After treatment,the Vm and PI of patients in the two groups were significantly higher than those before treatment,while the RI was significantly lower than that before treatment(P＜0.05).After treatment,the Vm and PI of patients in the observa-tion group were significantly higher than those in the control group,while the RI was significantly lower than that in the control group(P＜0.05).There was no statistically significant difference in serum TNF-α,IL-6,and CRP levels between the two groups before treatment(P＞0.05).The levels of serum TNF-α,IL-6,and CRP of patients in the two groups after treatment were significantly lower than those before treatment(P＜0.05).After treatment,serum TNF-α,IL-6,and CRP levels of patients in the observation group were significantly lower than those in the control group(P＜0.05).The incidence of adverse reactions in patients in the control group and observation group was 7.55％(4/53)and 9.09％(5/55),respectively,and the difference in the incidence of adverse reactions between the two groups was not statistically significant(P＞0.05).Conclusion Nimodipine combined with minimally invasive puncture can effectively improve the blood perfusion rate of HICH patients,reduce the degree of inflammatory response,and alleviate the patients'neurological function damage.

Objective:To document any effect of combining respiratory-muscle resistance training with feedback respiratory electrical stimulation in rehabilitating the diaphragm function and lung function of stroke survivors.Methods:Sixty hemiplegic stroke survivors were randomly assigned to an observation group or a control group, each of 30. Both groups were given conventional rehabilitation, including respiratory-muscle resistance training. The observation group additionally received feedback respiratory electrical stimulation twice a day, six days a week for 3 weeks. Before and after the treatment, ultrasound was used to measure the end-inspiratory and end-expiratory thickness of the diaphragm. Diaphragm movement during quiet breathing and deep breathing was also observed, and the diaphragm thickening fraction was calculated. The incidence of diaphragm dysfunction on the affected and healthy sides of the two groups before and after the treatment was also analyzed and compared.Results:Diaphragm dysfunction on either side had decreased significantly more in the observation group than in the control group after the treatment. The observation group also showed significantly greater average improvement in the thickening functions and in diaphragm movement on both the affected and healthy sides during quiet breathing and deep breathing. All of the pulmonary function indicators improved significantly in both groups after the treatment, but those of the observation group were, on average, significantly better than the control group′s averages.Conclusions:Combining 3 weeks of respiratory muscle resistance training with electrical stimulation feedback can effectively increase the bilateral thickness of the diaphragm and diaphragm movement in deep breathing of hemiplegic stroke survivors. That reduces the incidence of diaphragm dysfunction.
