OBJECTIVE To investigate the clinical characteristics of drug-induced liver injury （DILI） induced by glucagon- like peptide-1 receptor agonists （GLP-1RAs）， and to provide a reference for safe clinical medication. METHODS Using search terms such as “GLP-1”“GLP-1RAs”“semaglutide” “drug-induced liver injury”， relevant studies from PubMed， Embase， the Cochrane Library， CNKI， Wanfang Data and VIP were retrieved. Descriptive analysis was performed on cases of DILI induced by GLP-1RAs. RESULTS A total of 11 studies， comprising 11 patients， were included. Among them， 4 were male （36.4%） and 7 were female （63.6%）. Patient ages ranged from 17 to 64 years； 5 patients （45.5%） were between 50 and 65 years old. Six patients were treated for diabetes， and five for weight loss. Ten patients had underlying diseases. The shortest time to the onset of DILI was 5 days after medication， while the longest was approximately 180 days. The DILIs induced by GLP-1RAs were mainly hepatocellular injury type （6 cases）； severity levels included severe （3 cases）， moderate （6 cases）， and mild （2 cases）. Gastrointestinal symptoms and jaundice were the most common clinical manifestations. The association between DILI and GLP- 1RAs was assessed as “probable” in 10 cases and “possible” in 1 case. All 11 patients improved after drug discontinuation and （or） corresponding treatment. CONCLUSIONS DILI induced by GLP-1RAs is relatively concentrated in patients aged 50-65， with a higher incidence in females. The risk may be further increased in patients with underlying diseases. Clinical use of these agents should enhance pharmaceutical care， including identification of high-risk populations and patient education （especially symptom recognition）. When relevant symptoms appear， the drug should be discontinued immediately， with liver-protective therapy initiated when necessary， to ensure patient safety of drug use.

Objective:To compare the clinical efficacy of endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) in the treatment of elderly patients with early gastric cancer.Methods:Ninety-two elderly patients with early gastric cancer admitted to the 923th Hospital of the Joint Service Support Force of PLA from June 2019 to February 2022 were enrolled, and they were divided into ESD group (60 cases) and EMR group (32 cases) according to different surgical methods. The ESD group was treated with ESD surgery, while the EMR group was treated with EMR surgery. The short-term clinical efficacy of the two groups was compared. The gastric function including pepsinogen Ⅰ(PGⅠ), pepsinogenⅡ(PGⅡ), PGⅠ /PGⅡ ratio and the tumor markers including carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 125 (CA125), and invasion genes within the lesion including vascular endothelial growth factor C (VEGF-C), E-cadherin, microtubule depolymerin (Stathmin), Krüppel like factor 4 (KLF4) were detected before and 3 d after surgery. Followed up for 1 year, the recurrence rate and complications between the two groups were compared.Results:All of 92 patients successfully removed the diseased tissue as a whole, and the R0 and R1 resection rate between the two groups had no statistical differences ( P>0.05). At 3 d after surgery, the levels of PG Ⅰand PGⅠ/PG Ⅱin the both groups were higher than those before surgery, and the level of PG Ⅱ in the both groups was lower than that before surgery; the levels of PG Ⅰand PGⅠ/PG Ⅱ in the ESD group were higher than those in the EMR group: (86.50 ± 8.23) μg/L vs. (77.47 ± 7.40) μg/L, 5.29 ± 0.54 vs. 3.65 ± 0.50; the level of PG Ⅱ ratio in the ESD group was lower than that in the EMR group: (16.34 ± 3.05) μg/L vs. (21.20 ± 3.27) μg/L, there were statistical differences ( P<0.05). At 3 d after surgery, the levels of CEA, CA19-9 and CA125 in the two groups were decreased, and the levels of the above indicators in the ESD group were lower than those in the EMR group: (2.42 ± 0.45) μg/L vs. (3.29 ± 0.40) μg/L, (8.55 ± 2.10) kU/L vs. (10.62 ± 2.76) kU/L, (13.75 ± 4.28) kU/L vs. (17.20 ± 4.90) kU/L, there were statistical differences ( P<0.05). At 3 d after surgery, the mRNA expression of E-cadherin and KLF4 in the two groups were increased, and the mRNA expression of VEGF-C, Stathmin in the two groups were decreased, and the mRNA expression of E-cadherin and KLF4 in the ESD group were lower than those in the EMR group: 2.89 ± 0.31 vs. 3.03 ± 0.21, 2.90 ± 0.28 vs. 3.12 ± 0.37, and the mRNA expression of VEGF-C, Stathmin in the ESD group were higher than those in the EMR group: 0.45 ± 0.11 vs. 0.41 ± 0.07, 0.52 ± 0.23 vs. 0.43 ± 0.09, there were statistical differences ( P<0.05). The complication rate in the ESD group was lower than that in the EMR group: 5.00%(3/60) vs. 23.33% (14/60) , there was statistical difference ( χ2 = 8.32, P<0.01). The recurrence rate in the 1-year between the two groups had no statistical difference ( P>0.05). Conclusions:Compared with EMR, ESD is effective in the treatment of elderly early gastric cancer, which can better correct the abnormal secretion of pepsinogen, promote the functional recovery of gastric cells and glands, reduce the level of serum tumor markers, inhibit the metastasis and proliferation of tumor cells, and has good safety.

In the context of non-alcoholic fatty liver disease (NAFLD), characterized by dysregulated lipid metabolism in hepatocytes, the quest for safe and effective therapeutics targeting lipid metabolism has gained paramount importance. Sanhuang Xiexin Tang (SXT) and Baihu Tang (BHT) have emerged as prominent candidates for treating metabolic disorders. SXT combined with BHT plus Cangzhu (SBC) has been used clinically for Weihuochisheng obese patients. This retrospective analysis focused on assessing the anti-obesity effects of SBC in Weihuochisheng obese patients. We observed significant reductions in body weight and hepatic lipid content among obese patients following SBC treatment. To gain further insights, we investigated the effects and underlying mechanisms of SBC in HFD-fed mice. The results demonstrated that SBC treatment mitigated body weight gain and hepatic lipid accumulation in HFD-fed mice. Pharmacological network analysis suggested that SBC may affect lipid metabolism, mitochondria, inflammation, and apoptosis-a hypothesis supported by the hepatic transcriptomic analysis in HFD-fed mice treated with SBC. Notably, SBC treatment was associated with enhanced hepatic mitochondrial biogenesis and the inhibition of the c-Jun N-terminal kinase (JNK)/nuclear factor-kappa B (NF-κB) and extracellular signal-regulated kinase (ERK)/NF-κB pathways. In conclusion, SBC treatment alleviates NAFLD in both obese patients and mouse models by improving lipid metabolism, potentially through enhancing mitochondrial biogenesis. These effects, in turn, ameliorate inflammation in hepatocytes.

Objective:To upgrade the wisdom of traditional wards through the internet of things platform to achieve intelligent and refined management of wards, and to evaluate the effect of the upgrade.Methods:In June 2020, the convenience sampling method was used to selecte two wards of the cardiology department of Shandong First Medical University as the pilot units of the affiliated provincial Hospital to implement the intelligent ward management mode. Based on the principle of easy transformation, easy construction and easy maintenance, on the basis of realizing the full coverage of the internet of things, the hardware and software system were connected to complete the intelligent upgrade of the traditional ward, and the structured observation and semi-structured interview methods were adopted to evaluate the upgraded work efficiency and the use experience of patients.Results:The time spent on vital sign collection and recording, nursing risk assessment and time spent, and signage production and hanging were (4.24 ± 0.87), (4.07 ± 0.86) and 0 min respectively, which were effectively reduced than those before the upgrade (6.50 ± 2.95), (4.73 ± 1.62) and (1.13 ± 0.43) min, with statistically significant differences ( t=8.04, 3.99, 28.96, all P<0.01). The results of semi-structured interviews showed that patients perceived the smart ward as intelligent, saving manpower and waiting time; simple to operate, improving the experience of healthcare workers and patients in using it; and untimely system updates. Conclusions:The wisdom upgrade of traditional wards can help refine patient management, improve work efficiency, and improve the experience of health care workers and patients in using them, which will be continuously improved in future development and can provide practical paths for reference for the wisdom upgrade of similar wards.

Objective:To analyze the diagnostic value of high-frequency ultrasound combined with serum thyroid-stimulating hormone (TSH) / thyroglobulin (Tg) ratio for the benign and malignant lesions of thyroid nodules (TN).Methods:A retrospective analysis was made on the clinical data of 772 patients with TN admitted to Changxing County People′s Hospital from June 2020 to June 2021. All patients received high-frequency ultrasound examination and serum TSH detection, 320 patients (41.45%) received Tg detection to calculate the TSH/Tg ratio. According to the benign and malignant thyroid nodules, they were divided into benign group and malignant group based on the pathological results as the "gold standard". The ultrasonographic characteristics, serum TSH and Tg levels and TSH/Tg ratio of the two groups were compared, and the accuracy of high-frequency ultrasound, TSH/Tg ratio and the combination in the diagnosis of benign and malignant thyroid nodules were evaluated.Results:A total of 83 patients with thyroid nodules were diagnosed as malignant by pathological results. In the malignant group, the nodules were mostly irregular in shape, extremely low in internal echo, accompanied by calcification, aspect ratio ≥1 and enlarged cervical lymph nodes. The levels of TSH and Tg as well as the ratio of TSH/Tg in the malignant group were higher than those in the benign group (16.52 ± 4.49) mU/L vs. (6.75 ± 1.18) mU/L, (11.37 ± 3.16) kU/L vs. (8.14 ± 1.40) kU/L, 1.45 ± 0.76 vs. 0.83 ± 0.06, there were statistical differences( P<0.05). The sensitivity and accuracy of high-frequency ultrasound combined with TSH/Tg ratio in the diagnosis of benign and malignant thyroid nodules were 92.77%, 95.47%, and higher than those in the single diagnosis. Conclusions:The morphological high-frequency ultrasonography features of malignant thyroid nodules are mostly irregular, with extremely low internal echo, accompanied by calcification, aspect ratio ≥1 and cervical lymph node enlargement. TSH/Tg ratio is higher than that of benign thyroid nodules. The combination of high-frequency ultrasonography and TSH/Tg ratio can improve the diagnosis rate of thyroid cancer.
