ObjectiveTo explore the therapeutic effect of Xuebijing injection （XBJ） on severe acute pancreatitis induced acute lung injury （SAP-ALI） by regulating formyl peptide receptors （FPRs）/nucleotide-binding oligomerization domain-like receptor 3 （NLRP3） inflammatory pathway. MethodsSixty rats were randomly divided into a sham group， a SAP-ALI model group， low-， medium-， and high-dose XBJ groups （4， 8， and 12 mL·kg^-1）， and a positive drug （BOC2， 0.2 mg·kg^-1） group. For the sham group， the pancreas of rats was only gently flipped after laparotomy， and then the abdomen was closed， while for the remaining five groups， SAP-ALI rat models were established by retrograde injection of 5% sodium taurocholate （Na-Tc） via the biliopancreatic duct. XBJ and BOC2 were administered via intraperitoneal injection once daily for 3 d prior to modeling and 0.5 h after modeling. Blood was collected from the abdominal aorta 6 h after the completion of modeling， and the expression of interleukin （IL）-1β， IL-6， and tumor necrosis factor-α （TNF-α） in plasma was measured by enzyme-linked immunosorbent assay （ELISA）. The amount of ascites was measured， and the dry-wet weight ratios of pancreatic and lung tissue were determined. Pancreatic and lung tissue was taken for hematoxylin-eosin （HE） staining to observe pathological changes and then scored. The protein expression levels of FPR1， FPR2， and NLRP3 in lung tissue were detected by the immunohistochemical method. Western blot was used to detect the expression of FPR1， FPR2， and NLRP3 in lung tissue. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of FPR1， FPR2， and NLRP3 in lung tissue. ResultsCompared with the sham group， the SAP-ALI model group showed significantly decreased dry-wet weight ratio of lung tissue （P<0.01）， serious pathological changes of lung tissue， a significantly increased pathological score （P<0.01）， and significantly increased protein and mRNA expression levels of FPR1， FPR2， and NLRP3 in lung tissue （P<0.01）. After BOC2 intervention， the above detection indicators were significantly reversed （P<0.01）. After treatment with XBJ， the groups of different XBJ doses achieved results consistent with BOC2 intervention. ConclusionXBJ can effectively improve the inflammatory response of the lungs in SAP-ALI rats and reduce damage. The mechanism may be related to inhibiting the expression of FPRs and NLRP3 in lung tissue， which thereby reduces IL-1β and simultaneously antagonize the release of inflammatory factors IL-6 and TNF-α.

Tumor budding is a distinct pathomorphological feature observed in various types of solid tumor. In recent years， tumor budding has been recognized as an important biological feature associated with tumor invasion and metastasis， and it has become a new focus in the research on tumor progression. Although studies have explored the role of tumor budding in different types of tumor， there are studies in the field of hepatocellular carcinoma （HCC）. This article systematically reviews the research advances in tumor budding in HCC， with a focus on the mechanism of tumor budding， the association between tumor budding and tumor progression， and the potential application of tumor budding in prognostic assessment， in order to provide new insights and strategies for the early diagnosis and treatment of HCC.

BACKGROUND:The risk factors for patellofemoral pain syndrome are still unclear and research on risk factors is gradually becoming a hot topic in order to improve the therapeutic outcome of this disease. OBJECTIVE:To investigate the relationship between lower limb alignment and patellofemoral pain syndrome in young male runners. METHODS:In the same running population,21 patients with bilateral knee pain,29 patients with single knee pain and 20 normal runners were collected from January 2021 to July 2022.Full-length X-ray examination of both lower limbs in standing position was performed in all subjects.The lateral distal femoral angle,medial tibial proximal angle,joint line congruence angle,hip-knee-ankle angle,and knee physical valgus angle were measured and statistically analyzed. RESULTS AND CONCLUSION:There was no significant difference in the parameters between the left and right knees in each group(P>0.05).Compared with the normal group,no significant changes in lateral distal femoral angle,medial tibial proximal angle,joint line congruence angle,and hip-knee-ankle angle were observed in the single knee pain group and double knee pain group,while the knee physical valgus angle was significantly increased in these two groups(P<0.05).To conclude,increased knee physical valgus angle may be a risk factor for patellofemoral pain syndrome.

Objective:To explore the efficacy and safety of endoscopic radial incision (ERI) for congenital membranous duodenal stenosis (MDS).Methods:The clinical data of 13 children with MDS receiving ERI in the Department of Gastroenterology of Xi'an Children's Hospital from May 2017 to December 2021 were reviewed and analyzed. The perioperative management, surgical procedures, postoperative complications and follow-up were summarized.Results:There were 5 boys and 8 girls with a median disease duration of 8 (2-20) months, and the median age of diagnosis was 13 months (5-30 months). The septum of 10 cases (10/13) was located in the descending part of the duodenum, and that of 3 cases (3/13) in the horizontal part. The papilla of 1 case (1/13) opened on the septum, that of 3 cases (3/13) within 5 cm of the mouth side of the septum, and that of 9 cases (9/13) within 5 cm of the anal side of the septum. The median diameter of the septal aperture was 3 mm (2-6 mm). All 13 children successfully underwent ERI with a median operation time of 20 min (15-32 min). The average surgical incision was 3 strokes (2-4 strokes), and the endoscope with outer diameter 9.9 mm could pass stenosis after ERI. The median incision diameter was 10 mm (10-12 mm). All patients achieved relief of clinical symptoms after ERI. One patient (1/13) suffered from the postoperative delayed bleeding, which was stopped by endoscopic titanium clamping. No intestinal perforation or duodenal papilla injury occurred, and median postoperative hospital stay was 6 days (5-10 days). The upper gastrointestinal angiogram and gastroscopy were repeated 3 months after ERI, and the median diameter of stenosis was 12 mm (10-15 mm), which was significantly dilated compared with before. The mean body weight increase at 1 month after ERI was 1.20 kg (0.50-1.80 kg), and the mean body weight increase at 3 months was 3.50 kg (2.50-4.00 kg), which reached the normal body weight of the same age.Conclusion:ERI is safe and effective for the treatment of MDS in children, and shows good clinical application and promotion value.

OBJECTIVE To explore the regulatory mechanism of Danshen decoction on dyslipidemia in hyperlipidemia model rats. METHODS The experimental rats were divided into blank group （n＝9， no modeling）， model group （n＝8， modeling）， and Danshen decoction group （n＝9， modeling）. Starting from the 9th week of feeding with the high-fat diet， rats in the Danshen decoction group were given the corresponding medication solution （3.6 g/kg） intragastrically， while blank group and model group were given equal volume of normal saline， once a day， for 4 consecutive weeks. After 4 weeks of administration， the plasma levels of triglycerides （TG）， total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were measured in each group of rats； the pathological and morphological changes of liver tissue were observed； the differential proteins between samples were screened out by TMT quantitative proteomic analysis； the expression levels of the key differentially expressed proteins in the liver， including epoxide hydrolase 2 （EPHX2）， perilipin 2 （PLIN2）， peroxisome proliferator activated receptor γ （PPAR γ） and glycogen synthase kinase-3β （GSK-3β）were detected. RESULTS Compared with the model group， the plasma levels of TC， TG and LDL-C in the Danshen decoction group were significantly reduced （P＜0.05）， while the level of HDL-C was significantly increased （P＜0.05）. The liver tissue of rats inmodel group showed uneven staining， disordered arrangement of liver plates， disappearance of liver sinusoids， nuclearcondensation or disappearance of some cells， swelling and fusion of cytoplasm， proliferation of connective tissue， and diffuse vacuolar-like fat droplet changes. The liver tissue of Danshen decoction group showed varying degrees of improvement in the above pathological and morphological. The results of differential protein analysis showed that the total number of differential proteins was 298 between the model group and the blank group； the total number of differential proteins was 139 between the model group and Danshen decoction group. Compared with the model group， the expression levels of EPHX2 and PLIN2 proteins in the liver tissue of rats in the Danshen decoction group were significantly reduced （P＜0.01）， while the expression levels of GSK-3β and PPARγ were significantly increased （P＜0.01）. CONCLUSIONS Danshen decoction has a significant improvement effect on the plasma lipid levels and the pathological and morphological of the liver tissue in hyperlipidemia model rats. Its regulatory mechanism may be related to the up-regulation of PPARγ and GSK-3β expression and down-regulation of EPHX2 and PLIN2 expression， and the signaling pathways involved may include PPAR-γ signal pathway.

ObjectiveTo clarify the perception of the work and satisfaction levels among personnel conducting unified elderly care needs assessment in Shanghai， to analyze the factors influencing their job satisfaction， and to provide references for optimizing the job satisfaction of unified elderly care needs assessment personnel in Shanghai. MethodsA survey was conducted among 93 assessment personnel randomly selected from 29 elderly care needs assessment agencies in Shanghai. The personnel’s perception of their work and their levels of job satisfaction were examined. Chi-square test and Fisher’s precision probability test were used to compare regional differences， while the two-factor theory was employed to analyze the factors influencing job satisfaction. ResultsRegarding perception of the work， 92.5% of the surveyed personnel believed their work was important. Moreover， 87.1% were interested in their assessment tasks， and 84.9% believed they made a positive contribution to the assessment work and the assessment position was in line with their personal preferences. Regarding job satisfaction， 83.9% of the participants were satisfied with their assessment work， 78.5% considered the workload appropriate， and 74.2% found the working hours suitable. Additionally， 65.6% expressed satisfaction with the level of cooperation from the assessment subjects， while 94.6% and 91.4% of the personnel were satisfied with the support provided by the assessment agencies and had a sense of belonging， respectively. Furthermore， 65.6% of the personnel expressed satisfaction with their job compensation and benefits. Hygiene factors affecting job satisfaction included salary and compensation， workload， time spent on the job and institutional support related to external assistance， job suitability， teamwork， and client cooperation （P<0.05）， while motivational factors included recognition of the significance of the job， sense of achievement， interest in the job， sense of belonging， and opportunities for personal growth （P<0.05）. ConclusionThe overall work cognition and satisfaction of unified elderly care needs assessment personnel in Shanghai towards their work are relatively positive. Main issues include the heavy workload and actual job subsidies not meeting expectations. It is recommended to improve the standardization of the assessment process， establish a professional team of assessment personnel， and enhance the compensation and incentive mechanisms to continuously increase staff satisfaction.

Objective To explore the efficacy and safety of perforator flap eyelid reconstruction surgery for eyelid repair and reconstruction in patients with eyelid tumors after surgery.Methods Totally 80 patients(80 eyes)who re-ceived eyelid tumor surgery and planned to undergo the perforator flap eyelid reconstruction surgery in our hospital from January 2012 to December 2022 were included.All of them have early-stage and mid-stage eyelid tumors with no orbital or systemic metastasis.A perforator flap eyelid reconstruction surgery was conducted to treat the eyelid defects.The differ-ence in height and length of the palpebral fissure,aesthetic function scores and levels of depression and anxiety of patients before and after repair were compared;the clinical efficacy,adverse reactions and prognosis of patients were evaluated.Results Among the 80 eyes,there were 35 eyes with significant effect,35 eyes with effective impact,and 10 eyes with no effect,with a total effective rate of 87.5％.The height and length of palpebral fissure of patients after repair were(1.49±0.47)mm and(1.43±0.55)mm,respectively,which were significantly lower than those before repair[(2.55± 0.35)mm and(2.38±0.49)mm](both P＜0.01).The aesthetic function score before repair was 0.91±0.23,and that after repair was 1.87±0.19,with a significant difference(P＜0.01).The scores of the Self-rating Anxiety Scale and Self-rating Depression Scale after repair were 40.14±6.54 and 39.45±7.65,respectively,which were significantly lower than those before repair(59.56±8.23 and 57.93±8.19)(both P＜0.01).Among the 80 patients,the total incidence of compli-cations was 27.5％(22/80).All patients were followed up for 6-36 months,with an average follow-up time of(12.39± 6.17)months.No tumor recurrence was found during the follow-up.All composite flaps survived without infection,necro-sis or displacement.Conclusion The perforator flap eyelid reconstruction surgery has a good and safe therapeutic effect on repairing full-layer eyelid defects in patients who underwent eyelid tumor surgery.

Objective:To investigate the value of three-dimensional reconstruction combined with serum carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) detection in the diagnosis and resectability evaluation of hilar cholangiocarcinoma (HCCA) before resectable lymph node metastasis.Methods:A total of 65 patients with suspected HCCA who were treated at Yiwu Central Hospital from June 2019 to June 2022 were included in the observation group. Thirty healthy people who concurrently underwent physical examinations in the same hospital were included in the control group. All participants underwent a CT three-dimensional reconstruction examination. Simultaneously, the automatic electrochemiluminescence immunoassay analyzer was used to measure serum levels of CA19-9 and CEA. The outcomes of percutaneous transhepatic cholangiography were used as the "gold standard". The consistency between CT three-dimensional reconstruction, CA19-9 detection, and CEA detection, either individually or combined, and the "gold standard" in the diagnosis of HCCA was evaluated.Results:Serum levels of CA19-9 and CEA in the observation group were (62.71 ± 10.63) U/mL and (62.71 ± 10.63) ng/mL, respectively, which were significantly higher than those in the control group [(12.37 ± 7.39) U/mL, (1.31 ± 0.97) ng/mL, t = 23.43, 11.59, both P < 0.05). The levels of CA19-9 [(71.69 ± 12.37) U/mL] and CEA [(8.89 ± 3.51) ng/mL] in patients with HCCA who had lymph node metastasis were significantly higher than those in patients with HCCA who had no lymph node metastasis [CA19-9 (56.78 ± 10.16) U/mL, CEA (6.45 ± 2.11) ng/mL, t = 4.14, 2.76, both P < 0.05].Compared with histopathological examination, the accuracy of CT three-dimensional reconstruction in typing was 85.00%. According to the "gold standard" diagnosis, CT three-dimensional reconstruction, CA19-9 detection, and CEA detection, alone and their combination, successfully detected HCCA in 22 cases (55.00%), 26 cases (65.00%), 31 cases (77.50%), and 38 cases (95.00%), respectively. The detection rate of HCCA was the highest when CT three-dimensional reconstruction, CA19-9 detection, and CEA detection were combined, and the difference was statistically significant ( χ2 = 18.15, P < 0.05). Compared with CT three-dimensional reconstruction (AUC: 0.808), CA19-9 detection (AUC: 0.721), and CEA detection (AUC: 0.703) individually, their combination (AUC: 0.913) had the highest value in the diagnosis of HCCA (all P < 0.05). Conclusion:CT three-dimensional reconstruction, CA19-9 detection, and CEA detection have a certain diagnostic value for HCCA, but the combination of CT three-dimensional reconstruction with the detection of serum levels of CA19-9 and CEA has a higher diagnostic value for HCCA, providing an effective reference for the preoperative evaluation of the resectability of HCCA in the clinic.
