OBJECTIVE To investigate the therapeutic effect and mechanism of Qiwei dongqingye powder (QDP) on bronchial asthma in mice. METHODS The mice were divided into blank group (normal saline), model group (normal saline), dexamethasone group (2 mg/kg), and QDP low-, medium-, and high-dose groups (200, 400, 800 mg/kg), with 14 mice in each group. Except for the blank group, mice in all other groups were given ovalbumin via intraperitoneal injection followed by aerosol inhalation to induce a bronchial asthma model. During the modeling process, mice in each group were administered corresponding drug solutions or normal saline intragastrically/intraperitoneally. After the last medication, the number of cells in the bronchoalveolar lavage fluid (BALF) of the mice was observed and counted; the pathological changes of the bronchus and lung tissue were observed; the levels of malondialdehyde (MDA), nitric oxide (NO), total superoxide dismutase (T-SOD), and glutathione peroxidase (GSH-Px) in the lung tissue of the mice were determined, and the level of interleukin-17 (IL-17) in the BALF and serum was determined. Transcriptomics was employed to predict and validate the mechanism of action of QDP against bronchial asthma. RESULTS Compared with the model group, the total cell count, neutrophil count, lymphocyte count, and macrophage counts in the BALF of the QDP high-dose group were all significantly reduced ( P <0.05); the levels of MDA and NO in the lung tissue, and the levels of IL-17 in the BALF and serum were all decreased significantly ( P <0.05); the levels of T-SOD and GSH-Px were significantly increased ( P <0.05); the arrangement of lung tissue cells tended to normalize, with reduced infiltration of inflammatory cells and decreased exfoliation of bronchial simple columnar epithelial cells. The transcriptomic results revealed that the differentially expressed genes were B-cell receptor signaling pathway, nuclear factor κB (NF-κB) signaling pathway, ferroptosis signaling pathway, and others. Further validation revealed that, compared with the model group, the expression levels of NF-κB p65 and chemokine ligand 20, as well as the phosphorylation level of NF-κB inhibitor protein α, were significantly decreased in the lung tissues of the mice in all QDP groups ( P <0.05). Conversely, the protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) were significantly increased ( P <0.05). CONCLUSIONS QDP can effectively alleviate bronchial asthma by inhibiting the NF-κB signaling pathway, activating the Nrf2/HO-1 signaling pathway, regulating oxidative stress, and reducing inflammatory responses.

OBJECTIVE To investigate the effects of subanesthetic dose of esketamine on postoperative anxiety and recovery in patients undergoing laparoscopic cholecystectomy. METHODS A total of 200 patients scheduled for laparoscopic cholecystectomy at Suzhou Ninth Hospital Affiliated to Soochow University from January 2023 to December 2024 were randomly assigned to control group (n=100) and observation group (n=100). One minute before the initiation of anesthesia, patients in the control group received intravenous injections of Propofol emulsion injection, Sufentanil citrate injection, and Succinylcholine chloride injection. On this basis, patients in the observation group received an intravenous injection of Esketamine hydrochloride injection. The anxiety status of patients in both groups was compared, along with their general intraoperative conditions (including sufentanil dosage, duration of pneumoperitoneum, operative time, anesthesia time, and extubation time), postoperative recovery, incidence of adverse reactions, and the need for dezocine rescue analgesia. Heart rate and mean arterial pressure, entropy index (state entropy and response entropy), inflammatory marker levels [interleukin-6 (IL-6) and C-reactive protein (CRP)], numerical rating scale (NRS) for pain intensity were compared between the two groups at different time points. RESULTS No significant differences were found between the two groups in pneumoperitoneum duration, operative time, anesthesia time,extubation time, incidence of postoperative dry mouth, entropy index or length of stay in the post-anesthesia care unit (P>0.05). Compared with the control group, the observation group showed significantly lower postoperative STAI-S scores, reduced intraoperative sufentanil consumption, decreased incidence of postoperative nausea, vomiting, and shivering, the need for dezocine rescue analgesia, as well as lower plasma IL-6 and CRP levels at 24 h after surgery, and NRS (P<0.05). The heart rate and mean arterial pressure of patients in the observation group at the start of surgery, end of surgery, and during extubation were all significantly higher than those in the control group (P<0.05). CONCLUSIONS Subanesthetic dose of esketamine can effectively alleviate postoperative anxiety, reduce intraoperative opioid consumption, suppress postoperative inflammatory response, relieve postoperative pain, and promote recovery in patients undergoing laparoscopic cholecystectomy.

Based on advancements in modern medical research regarding the intricate connection between the endocrine and exocrine functions of the pancreas, as well as the relationship between pancreatic functions and traditional Chinese medicine (TCM) spleen system, this paper discussed the categorization of the pancreas. It is proposed that the pancreas is neither a true zang organ nor a fu organ, but possessed the attributes of an extraordinary fu-organ and can be classified under the spleen. The spleen governs transportation and transformation, ascent of the clear and dispersion of essence, which encompasses the endocrine and exocrine functions, and pancreatic enzymes and glucose-regulating hormones form the material basis for the spleen's function of dispersing essence. Diseases of the pancreas exhibit characteristics of both zang-organ deficiency and fu-organ excess, so treatment should simultaneously supplement zang-organ disease and regulate fu-organ disease when pancreas showing endocrine and exocrine co-morbidities, with focus on restoring the pancreas (spleen)'s dispersing essence function. Therapeutic strategies include supplementing spleen qi, nourishing spleen yin to strengthen spleen earth, unblocking spleen collaterals, raising spleen yang, and removing spleen turbidity to support the spleen's dispersing essence function, so as to replenish the essential qi of zang-fu organs, ensure their distribution throughout the body, and improve the endocrine and exocrine functions of the pancreas.

Background and aims:Metabolic dysfunction-associated fatty liver disease(MAFLD)is a common chronic condition that can lead to cancer due to its complex pathogenesis.Therapeutic agents targeting AMP-activated protein kinase(AMPK)activation have been suggested as potential treatments for metabolic disorders such as metabolic dysfunction-associated steatohepatitis(MASH).Rhizoma Atractylodis Mac-rocephalae(RAM)has been clinically used to treat obesity-related health problems,but its therapeutic effects on MAFLD and the underlying mechanism remain unclear.Therefore,this study was conducted to evaluate the function and underlying mechanism of RAM in the treatment of MAFLD.Methods:The effect of RAM decoction on MAFLD was evaluated using a high-fat diet(HFD)-induced MAFLD mouse model.In vitro studies were conducted using a palmitic acid/oleic acid-induced lipid accumulation model in the alpha mouse liver 12 cells and RAM-containing serum.The underlying mechanisms were elucidated through a combination of network pharmacology analysis,immunohis-tochemistry,western blotting,and polymerase chain reaction analysis.Results:Administration of RAM decoction significantly reduced body weight gain in MAFLD mice without changing food intake.The weights of the liver and inguinal adipose tissues were also reduced after RAM treatment.Additionally,RAM administration decreased serum levels of alanine aminotrans-ferase,aspartate transaminase,total cholesterol,triglyceride,low-density lipoprotein cholesterol,and glucose,while reducing lipid droplet accumulation in the liver tissues of MAFLD mice.The underlying mechanisms included the activation of the phosphorylation of AMPK and acetyl-CoA carboxylase(ACC),and inhibition of the expression of sterol regulatory element binding protein 1(SREBP1).However,RAM did not alter the protein expression levels of peroxisome proliferator-activated receptor α and carnitine palmitoyltransferase-1α.Furthermore,the RAM-induced upregulation of phosphorylated AMPK,phos-phorylated ACC,and SREBP1 expression,as well as the downregulation of fatty acid synthase expression,were reversed by using an AMPK inhibitor.Conclusions:Through a combination of network pharmacology and experimental validation,we demonstrated that RAM may exert therapeutic effects on MAFLD by inhibiting lipid synthesis and activating phosphorylated AMPK pathways.

Objective:To compare the clinical efficacy and safety of bronchial artery chemoembolization (BACE) combined with anlotinib (BACE+A) versus BACE alone in patients with stage III-IV non-small cell lung cancer (NSCLC).Methods:A total of 94 patients with advanced NSCLC treated at six interventional centers between November 2020 and November 2021 were retrospectively enrolled. Patients were divided into the BACE+A group ( n=46) and the BACE alone group ( n=48) based on treatment regimen. Baseline and perioperative clinical data were collected and compared between the two groups. Treatment response was evaluated using the modified Response Evaluation Criteria in Solid Tumors (mRECIST) at 1, 6, and 12 months after the first BACE procedure. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and treatment-related adverse events (AEs) were recorded. Kaplan-Meier survival curves were plotted to compare median OS and PFS between groups. Cox proportional hazards regression analysis was used to identify factors influencing OS and PFS. Results:The Kaplan-Meier analysis showed that the median OS was significantly longer in the BACE+A group (18.8 months, 95% CI 16.3-21.3) than in the BACE group (13.4 months, 95% CI 11.6-15.2) ( P=0.001). The median PFS was also significantly longer in the BACE+A group (9.0 months, 95% CI 7.3-10.7) compared to the BACE group (6.1 months, 95% CI 4.9-7.3) ( P=0.001). At 6 and 12 months post-first BACE, the ORR (43.5%, 40.0%) and DCR (89.1%, 83.3%) were significantly higher in the BACE+A group than in the BACE group (ORR: 20.8%, 14.8%; DCR: 66.7%, 59.3%) (all P<0.05). Multivariate Cox regression identified treatment with BACE+A ( HR=0.42, 95% CI 0.27-0.72, P=0.002), tumor stage ( HR=1.80, 95% CI 1.05-3.07, P=0.031), presence of pre-existing complications requiring intervention ( HR=2.72, 95% CI 1.65-4.50, P<0.001), and >2 BACE procedures ( HR=0.32, 95% CI 0.15-0.68, P=0.003) as independent factors influencing OS. Treatment with BACE+A ( HR=0.49, 95% CI 0.32-0.76, P=0.001), tumor stage ( HR=1.72, 95% CI 1.07-2.77, P=0.025), multi-arterial tumor blood supply ( HR=2.76, 95% CI 1.76-4.31, P<0.001), and>2 BACE procedures ( HR=0.40, 95% CI 0.22-0.71, P=0.002) were independent factors influencing PFS. There was no significant difference in BACE-related adverse events between the two groups (all P>0.05). Hypertension, fatigue, hand-foot syndrome, and anorexia were common anlotinib-specific adverse reactions in the combination group, but no grade 4 or higher adverse reactions were observed. Conclusions:BACE combined with anlotinib demonstrates superior efficacy compared to BACE alone in treating advanced NSCLC, significantly prolonging OS and PFS. The safety profile is manageable, with adverse events remaining within tolerable limits.

Objective:To establish a chain management model for blood glucose in critically ill patients after cardiac surgery and analyze its clinical effectiveness, and to provide a reference for related clinical nursing practices.Methods:A quasi-experimental study design was adopted. Using convenience sampling, 120 critically ill patients after cardiac surgery admitted to Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were selected as study subjects. They were divided into groups based on the time of admission to the intensive care unit after surgery. Sixty patients admitted from March to May 2024 were assigned to the control group and received conventional blood glucose management. Another 60 patients admitted from June to August 2024 were assigned to the observation group and received the chain management model for blood glucose control in addition to the conventional approach. Blood glucose levels and quality indicators of blood glucose management (including maximum blood glucose fluctuation, time in target glucose range, duration of insulin use, incidence of hypoglycemia, etc.) were compared between the two groups.Results:The control group included 27 males and 33 females, with an age of 63.00(59.00, 69.25) years; the observation group included 28 males and 32 females, with an age of 66.00(60.00, 70.00) years. The blood glucose levels of the observation group on postoperative days 2, 3, 4 were 9.10(8.68, 9.90), 8.90(8.40, 10.00), 8.75(7.38, 9.03) mmol/L, respectively, which were lower than those of the control group [10.30(9.80, 11.00), 9.95(9.40, 11.05), 9.30(8.10, 10.02) mmol/L], with a statistically significant difference ( Z=-5.85, -4.95, -3.50, all P<0.05). The maximum blood glucose fluctuation in the observation group was (4.09 ± 2.45) mmol/L, lower than that of the control group [(5.19 ± 2.47) mmol/L], with a statistically significant difference ( t=2.46, P<0.05). The time in the target glucose range was 67.00(60.00, 75.00)% in the observation group, higher than that of the control group 52.00(45.00, 60.00)%, with a statistically significant difference ( Z=-6.57, P<0.05). The duration of insulin use was 6.00(5.00, 7.00) h in the observation group, shorter than that of the control group [13.00(9.75, 15.32) h], with a statistically significant difference ( Z=-8.68, P<0.05). The incidence of hypoglycemia was 3.33%(2/60) in the observation group and 15.00%(9/60) in the control group, with a statistically significant difference ( χ2=4.90, P<0.05). The mechanical ventilation time, ICU stay, and total hospital stay in the observation group were 42.00(37.00, 89.25) h, 6.00(5.00, 7.00) d, and 12.00(11.75, 13.00) d, respectively, which were shorter than those of the control group [96.00(86.25, 98.00) h, 7.00(7.00, 10.00) d, and 13.00(11.75, 15.00) d], with a statistically significant difference ( Z=8.67, 17.57, 4.73, all P<0.05). Conclusions:The implemented chain management model for blood glucose control meets the comprehensive requirements of blood glucose management. It not only reduces blood glucose fluctuations and decreases the incidence of hypoglycemia but also effectively improves the quality of blood glucose management in critically ill patients after cardiac surgery, enhances the safety of blood glucose control, and promotes patient recovery.

Objective:To investigate the efficacy of anatomical resection (AR) in the early stages of treating solitary hepatocellular carcinoma (HCC) combined with liver cirrhosis with a diameter of ≤5 cm in comparison to different surgical methods of preferential hepatic parenchymal preservation (non-anatomical liver resection, NAR).Methods:The clinical data of 1 390 cases with solitary HCC combined with liver cirrhosis at an early stage who underwent liver resection at Mengchao Hepatobiliary Hospital of Fujian Medical University and six other medical centers from September 2013 to May 2019 were retrospectively analyzed. Patients were divided into the AR group (486 cases) and the NAR group (904 cases) and the wide surgical margin (WSM) group (745 cases) and the narrow surgical margin (NSM) group (645 cases) according to whether they received AR and the width of the surgical margin (1 cm). The basic information of the patients, preoperative evaluation index data, and postoperative follow-up (follow-up every 3 months) were collected. The Kaplan-Meier method was used to plot the survival curve.The log-rank test was used to compare the difference in survival between the two groups. The Cox proportional hazards regression model was used to analyze the factors affecting the prognosis. Propensity score matching (PSM) was applied to reduce intergroup bias.Results:The overall survival (OS) rates for all patients at 1, 3, and 5 years were 95.5%, 79.9%, and 63.5%, respectively. The recurrence-free survival (RFS) rates were 81.5%, 59.0%, and 43.7%, respectively. There was a statistically significant difference in RFS rate between the AR group and the NAR group prior to PSM, but no statistically significant difference in OS rate (RFS rate: 47.0% vs. 41.9%, P<0.05; OS rate: 64.4% vs. 62.9%, P>0.05). The postoperative RFS rate and OS rate were significantly superior in the WSM group than those of the NSM group (RFS rate: 47.8% vs. 37.2%, P<0.001; OS rate: 69.0% vs. 57.3%, P<0.001). There was no statistically significant difference in OS rate and RFS rate between the AR group and the NAR group following PSM (RFS: 46.3% vs. 45.1%, P>0.05; OS rate: 64.0% vs. 64.3%, P>0.05).The 5-year OS and RFS rates in the WSM group were 66.8% and 60.2%, respectively. The 5-year OS and RFS rates for the NSM group were 48.7% and 41.4%, respectively, with a statistically significant difference ( P<0.05). Cox multivariate analysis indicated that serum albumin, tumor diameter, microvascular invasion, and surgical margin were independent prognostic factors affecting OS and RFS. The Child-Pugh grade and satellite lesions were independent prognostic factors affecting OS. Conclusion:Anatomical liver resection is not an independent risk factor for prognosis, but the state of the resection margin determines the prognosis of patients with solitary HCC combined with cirrhosis. Therefore, hepatic resection margins should be prioritized in such patients.

Objective:To investigate the association of blood lipids and body mass index (BMI) with hyperuricemia (HUA) in the elderly.Methods:It was a cross-sectional study. A total of 114 391 elderly individuals received health examinations at primary healthcare institutions in Wujin District from January to December in 2022. The health examination included questionnaire survey, physical examination and laboratory examination. The multivariate logistic regression and restricted cubic spline (RCS) plots were used to analyze the association and dose-response relationship of blood lipid and BMI with HUA. The mediating effect model was used to explore the mediation effect of BMI on the association between blood lipid and HUA.Results:Among the 112 415 subjects, 18 506 (16.46%) were checked with HUA. After adjusting for relevant confounders, total cholesterol (TC) ( OR=1.20, 95% CI: 1.16-1.23), triglyceride (TG) ( OR=1.46, 95% CI: 1.44-1.49), high density lipoprotein cholesterol (HDL-C) ( OR=0.74, 95% CI: 0.73-0.76), low density lipoprotein cholesterol (LDL-C) ( OR=1.14, 95% CI: 1.12-1.15) and BMI ( OR=1.42, 95% CI: 1.39-1.44) were all associated with HUA (all P0.05). The RCS analysis revealed that TG, HDL-C, and LDL-C each exhibited a nonlinear dose-response relationship with HUA, the inflection points was 3.00 mmol/L, 1.57 mmol/L and 2.50 mmol/L, respectively (all P-nonlinear0.001). The results of interaction showed that there were additive interaction between high TC( S=1.27 , 95% CI: 1.17-1.37), high TG( S=1.32 , 95% CI: 1.25-1.40), high LDL-C( S=1.23 , 95% CI: 1.14-1.34) and overweight/obesity with HUA (all P0.05). The results of mediation effect analysis showed that the mediation effect of BMI on the association between blood lipids (HDL-C, LDL-C, TG and TC) and HUA, from high to low, were as follows: 22.5% (95% CI: 20.8%-24.2%), 13.9% (95% CI: 12.0%-16.2%), 13.5% (95% CI: 12.7%-14.4%) and-3.9% (95% CI:-6.6%--1.8%). Conclusion:The blood lipid levels and BMI are positively correlated with HUA in the elderly.

Objective:This study aims to explore clinical subtypes of Garden typeⅠfemoral neck fractures and develop corresponding reduction strategies based on the characteristics of the fractures.Methods:A retrospective analysis was conducted on the data of 256 patients with Garden type I femoral neck fractures admitted to Tianjin Hospital from January 2015 to January 2018. There were 89 males and 167 females included, with a mean age of 56.5±12.8 years (range, 17-86 years), and with 159 on the left side and 97 on the right side. According to the anteroposterior and lateral X-ray images, the fractures were further classified into two subtypes: 111 cases of Garden type I a (simple abduction without hypsokinesis of the femoral head), characterized by abduction and impaction of the femoral head on anteroposterior images, and no obvious hypsokinesis of the femoral head or only central impaction of the femoral head on lateral images; 145 cases of Garden I b type (femoral head abduction with hypsokinesis), characterized by abduction and impaction of the femoral head on anteroposterior images, and remarkable hypsokinesis on lateral images. The injury mechanism of type I a involved abduction and impaction caused by the violent extension, abduction, and external rotation of the hip joint. Mild flexion and adduction of the hip joint can be used to reduce the abduction and impaction. The injury mechanism of type I b is similar to type Ia in the first stage, but the violence continues to increase and leading to significant hypsokinesis of the femoral head. Reduction was achieved by excessive flexion, adduction, and mild internal rotation, tilting the femoral head backward to facilitate reduction. The surgical strategy were close reduction and cannulated screw fixation (three cannulated screws in an "inverted triangle" arrangement). Postoperatively, anteroposterior and lateral X-rays were taken immediately to assess the quality of reduction, including the Garden index, Lowell "S" curve, and screw placement. During follow-up, fracture healing and complications were recorded, and Harris score was used to evaluate hip joint function at the final follow-up.Results:All patients successfully received operative therapy and were followed up with a mean of 7.1±1.9 years (range, 5-10 years). Garden index showed 91.4%(234/256) achieved anatomical reduction, with an excellent reduction rate of 97.3%(249/256). The excellent rate of the Lowell "S" curve was 97.7%(250/256), and the excellent and good rate for screw insertion was 98.8%(253/256). All patients achieved primary fracture healing without infection, nonunion of fractures, failure of internal fixation, or other complications. Two patitents with Garden I b fractures (0.8%) developed femoral head necrosis due to premature weight-bearing at 9 and 12 months postoperatively, respectively, after fracture healing. However, with strict hip preservation treatment, their symptoms resolved without further progression of necrosis or need for reoperation. At the final follow-up, the mean Harris score was 93.9±4.5 points (range, 81-100 points), with an excellent and good rate of 98.8%(253/256).Conclusions:Garden I femoral neck fractures can be categorized into two subtypes based on their characteristics and injury mechanisms. Adopting corresponding reduction methods according to subtypes can achieve anatomical reduction and favorable early to mid-stage therapeutic outcomes (primary fracture healing and low incidence of femoral head necrosis).
