Purpose The study aimed to analyze the relationship between MET gene variants and clinicopathologi-cal features in patients with non-small cell lung cancer(NSCLC).Methods Next-generation sequencing technology was used to detect MET gene variants in NSCLC specimens.The association between MET gene variant status and clini-copathological features was then analyzed.Results Among 1 633 cases of NSCLC,the overall MET mutation rate was 4.53%(74/1 633).Variants were mainly observed in male patients,never-smokers,those older than 60 years,ade-nocarcinoma histology,and patients with TNM stage Ⅲ+Ⅳ disease(P<0.05).MET gene variant status showed no significant assocication with patient age,sex,smoking history,or pathological subtype(P>0.05),but was statistical-ly correlated with clinical stage and presence of distant metastasis(P<0.05).The two major variant types were MET exon 14 skipping and MET amplification,which together accounted for 71.62%of all variants.In addition,MET am-plification was positively correlated with EGFR(P=0.003,rs=0.340)and TP53 mutations(P=0.002,rs=0.362),but showed no correlation with KRAS or ALK gene mutations.In contrast,MET exon 14 skipping was nega-tively correlated with EGFR gene mutations(P<0.001,rs=-0.409),and showed no significant correlation with KRAS,ALK,or TP53 mutations.Conclusion Different types of MET gene variants(amplification,exon 14 skip-ping,fusion,and others)are significantly associated with clinical advanced clinical stage and distant metastasis in NSCLC,but are independent of patient age,sex,smoking history,and pathological subtype.MET amplification fre-quently co-occur with EGFR and TP53 co-mutations.

ObjectiveTo investigate the association between cumulative atherogenic index of plasma (cumAIP) and the risk of new-onset nonalcoholic fatty liver disease (NAFLD) in young and middle-aged individuals. MethodsA prospective cohort study was conducted among the young and middle-aged individuals (aged 18 to <60 years) in the Kailuan study cohort who underwent physical examination in Kailuan General Hospital and its 10 affiliated hospitals in June 2006 to October 2010, and after screening based on the inclusion and exclusion criteria, 33 987 individuals were included in the observation cohort. The individuals were divided into Q1, Q2, Q3, and Q4 groups based on the quantiles of cumAIP. The Kaplan-Meier method was used to calculate the cumulative incidence rate of new-onset NAFLD in the four groups, while the log-rank test was used for comparison between groups. A multivariate Cox regression analysis was used to obtain the hazard ratio (HR) and 95% confidence interval (CI) of the risk of new-onset NAFLD in the four groups. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups; the chi-square test was used for comparison of categorical variables between groups. ResultsThe mean follow-up was 10.89±2.54 years, and there were 6 011 cases of new-onset NAFLD, including 995 cases in the Q1 group, 1 366 in the Q2 group, 1661 in the Q3 group, and 1 989 in the Q4 group, with an incidence density of 11.37, 16.02, 19.97, and 24.91 per thousand person-years. The log-rank test showed that there was a significant difference in cumulative incidence rate between the four groups (P<0.001). With the presence or absence of NAFLD as the dependent variable and the quantiles of different exposure levels to cumAIP as the independent variable, the multivariate Cox regression model analysis showed that compared with the Q1 group, the Q2, Q3, and Q4 groups had an HR of 1.30 (95%CI: 1.20 — 1.41), 1.52 (95%CI: 1.41 — 1.65), and 1.79 (95%CI: 1.64 — 1.95), respectively, for new-onset NAFLD, with a Ptrend value of <0.001. With the presence or absence of new-onset NAFLD as the dependent variable and the cumulative exposure to AIP for 0, 2, 4, and 6 years as the independent variable, the Cox regression analysis showed that compared with cumulative exposure to AIP for 0 years, cumulative exposure to AIP for 2, 4, and 6 years had an HR of 1.24 (95%CI: 1.15 — 1.35), 1.51 (95%CI: 1.40 — 1.64), and 1.70 (95%CI: 1.56 — 1.84), respectively, with a Ptrend value of <0.001. A sensitivity analysis was performed after exclusion of the individuals with new-onset NAFLD within 2 years, the individuals who experienced atherosclerotic cardiovascular disease events during follow-up, and the individuals taking antihypertensive, hypoglycemic, and lipid-lowering drugs, and the results were similar to those of the main analysis. Considering the competitive relationship between all-cause death and outcome events, a competing risk analysis of death was performed, which showed that the results of risk analysis were similar to those of the main analysis. ConclusionA high level of cumAIP exposure can increase the risk of new-onset NAFLD in young and middle-aged individuals.

Objective:To evaluate the safety and effectiveness of pecto-intercostal fascial plane (PIFP) block and erector spinae plane (ESP) block for postoperative analgesia in median open heart surgery.Methods:A total of 158 patients who underwent elective midline open heart surgery at the Nanjing First Hospital, Nanjing Medical University from October 2022 to October 2023 were randomly divided into a PIFP block group (P group) and ESP block group (E group) using a random number table method, with 79 patients in each group. Before anesthesia surgery, the group P underwent ultrasound-guided bilateral PIFP block, while the group E underwent ultrasound-guided bilateral ESP block. Both groups received sufentanil intravenous patient-controlled analgesia after surgery. The resting and activity Visual Analog Scale (VAS) scores of two groups of patients at 6, 12, 18, and 24 hours after surgery were recorded; The first press time of the patient′s postoperative patient-controlled analgesia pump, the cumulative dose of sufentanil within 24 hours, the number of effective presses, and the rate of salvage analgesia were recorded; and extubation time, intensive care unit (ICU) stay, and adverse reactions; the time of nerve block operation, clarity score of puncture needle imaging under ultrasound, and patient satisfaction with nerve block were also recorded.Results:There was no statistically significant difference in resting VAS scores and activity VAS scores between the two groups at 6, 12, 18, and 24 hours after surgery (all P>0.05). The activity VAS scores of the group P were lower than those of the group E at 6 and 12 hours after surgery (all P<0.05); Compared with the group E, patients in the group P had significantly longer first press time of postoperative analgesia pump (all P<0.05), lower salvage analgesia rate, cumulative dose of sufentanil 24 hours after surgery, and fewer effective presses of analgesia pump (all P<0.05); There was no statistically significant difference in extubation time, ICU stay, and incidence rate of nausea between the two groups of patients (all P>0.05); Compared with the group E, the group P had shorter nerve block operation time, higher clarity score of puncture needle imaging under ultrasound, and higher patient satisfaction (all P<0.05). Conclusions:Compared with ESP block, PIFP block can provide better perioperative analgesia for cardiac surgery patients, reduce the use of opioid drugs, and the operation of PIFP block is simpler, with good safety and effectiveness.

Objective:To retrieve and summarize the evidence for postoperative observation time and bed rest time in patients undergoing percutaneous renal biopsy, so as to provide evidence-based basis for postoperative nursing of patients undergoing percutaneous renal biopsy.Methods:Using search terms such as "renal biopsy" and "renal puncture", based on the "6S" evidence resource pyramid model, evidence on postoperative observation time and bed rest time of percutaneous renal biopsy patients, including guidelines, best practice information books, evidence summaries, systematic reviews, expert consensus, and original research, was systematically searched on various guideline websites, evidence-based databases, original research databases, and professional association websites both domestically and internationally. The search period was from database establishment to July 1, 2023. After independent evaluation of the included literature by two researchers, evidence was extracted and summarized from the literature that met the quality standards.Results:A total of nine articles were included, including one guideline, five cohort studies, and three cross-sectional studies. This study summarized six best pieces of evidence from two aspects, namely postoperative observation time and postoperative bed rest time. For patients with low risk of complications after percutaneous renal biopsy, it was recommended to observe for 6 to 8 hours after surgery, but further shortening the observation time to 4 to 5 hours may also be safe and sufficient. For patients with high risk of complications after percutaneous renal biopsy, those living far from the hospital, those living alone, or those who may experience significant psychological stress after biopsy, it was recommended to extend the observation time to up to 24 hours.Conclusions:Based on existing evidence, it seems feasible to shorten the bed rest time after percutaneous renal biopsy. A large amount of high-quality research is still needed to explore the optimal postoperative bed rest time.

Objective:
To investigate the effect of Guangdong Shenqu (GSQ) on intestinal flora structure in mice with food stagnation through 16S rDNA sequencing.
Methods:
Mice were randomly assigned to control, model, GSQ low-dose (GSQL), GSQ medium-dose (GSQM), GSQ high-dose (GSQH), and lacidophilin tablets (LAB) groups, with each group containing 10 mice. A food stagnation and internal heat mouse model was established through intragastric administration of a mixture of beeswax and olive oil (1:15). The control group was administered normal saline, and the model group was administered beeswax and olive oil to maintain a state. The GSQL (2 g/kg), GSQM (4 g/kg), GSQH (8 g/kg), and LAB groups (0.625 g/kg) were administered corresponding drugs for 5 d. After administration, 16S rDNA sequencing was performed to assess gut microbiota in mouse fecal samples.
Results:
The model group exhibited significant intestinal flora changes. Following GSQ administration, the abundance and diversity index of the intestinal flora increased significantly, the number of bacterial species was regulated, and α and β diversity were improved. GSQ administration increased the abundance of probiotics, including Clostridia, Lachnospirales, and Lactobacillus, whereas the abundance of conditional pathogenic bacteria, such as Allobaculum, Erysipelotrichaceae, and Bacteroides decreased. Functional prediction analysis indicated that the pathogenesis of food stagnation and GSQ intervention were primarily associated with carbohydrate, lipid, and amino acid metabolism, among other metabolic pathways.
Conclusion
The digestive mechanism of GSQ may be attributed to its role in restoring diversity and abundance within the intestinal flora, thereby improving the composition and structure of the intestinal flora in mice and subsequently influencing the regulation of metabolic pathways.

Ethylene glycol, also known as glycol, is a common low-temperature antifreeze used in automobiles. It is a colorless, odorless, volatile, low-sweet, sticky liquid at room temperature. Ethylene glycol is easily decomposed and absorbed through the digestive tract. Toxic metabolites cause serious clinical symptoms such as central nervous system inhibition, metabolic acidosis, cardiopulmonary symptoms and renal insufficiency, and even death. Misuse and oral suicide are the main causes of ethylene glycol poisoning. This article reports a case of severe ethylene glycol poisoning admitted to the emergency department of the Affiliated Hospital of Hangzhou Normal University in December 2021. After treatment with V-V ECMO combined with blood purification, the patient was improved and discharged from hospital.

The aim of the present study is to explore the association between abdominal obesity and chronic kidney disease (CKD) through a systematic review of published studies. Databases including Wanfang data, CNKI, VIP, CBM, Cochrane Library, PubMed, Web of science and Embase were searched up to July 2021 to collect longitudinal studies published in Chinese and English on the association between abdominal obesity and CKD. In order to avoid omission, reference lists of related articles were also checked manually. After literature selection, data were extracted and study quality was evaluated by the Newcastle-Ottawa scale. Statistical analysis of this study was conducted using Stata 11.0 software. Finally, five studies were included in this study. The results showed that abdominal obesity defined by waist circumference was not associated with CKD (OR=1.17,95% CI:0.93-1.48). According to the results of subgroup analyses, whether adjusted body mass index might be part of the reason of heterogeneity. Based on results of this study, the association between abdominal obesity defined by waist hip ratio and CKD, as well as the association between abdominal obesity and CKD in different genders, remains unknown. In conclusion, abdominal obesity might not be associated with incident CKD. However, more studies are needed in the future to explore this association.

Loofah seeds ribosome inactivating protein luffin-α was fused with a tumor-targeting peptide NGR to create a recombinant protein, and its inhibitory activity on tumor cells and angiogenesis were assessed. luffin-α-NGR fusion gene was obtained by PCR amplification. The fusion gene was ligated with pGEX-6p-1 vector to create a recombinant plasmid pGEX-6p-1/luffin-α-NGR. The plasmid was transformed into E. coli BL21, and the target protein was isolated and purified by GST affinity chromatography. The luffin-α-NGR fusion gene with a full length of 849 bp was successfully obtained, and the optimal soluble expression of the target protein was achieved under the conditions of 16 ℃, 0.5 mmol/L IPTG after 16 h induction. SDS-PAGE and Western blotting confirmed the recombinant protein has an expected molecular weight of 56.6 kDa. Subsequently, the recombinant protein was de-tagged by precision protease digestion. The inhibitory effects of the recombinant protein on liver tumor cells HepG2 and breast cancer cells MDA-MB-231 were significantly stronger than that of luffin-α. The Transwell and CAM experiment proved that the recombinant protein luffin-α-NGR also had a significant inhibitory effect on tumor cells migration and neovascularization. The inhibitory activity on tumor cells and angiogenesis of the recombinant luffin-α-NGR protein lays a foundation for the development of subsequent recombinant tumor-targeting drugs.
