Objective:To explore the risk factors related to delayed pleural effusion in multiple trauma patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 145 multiple trauma patients admitted to the First Affiliated Hospital of Soochow University from January 2022 to October 2023, including 99 males and 46 females, aged 18-81 years [56.0(46.5, 64.5)years]. Based on whether delayed pleural effusion developed after injury, the patients were divided into delayed pleural effusion group ( n=66) and non-delayed pleural effusion group ( n=79). The clinical data of the patients in both groups were collected, including gender, age, underlying disease (diabetes mellitus and hypertension), cause of injury (traffic injury, blow injury, fall from height, and others), comorbid injuries (traumatic brain injury, maxillofacial fracture, clavicular fracture, scapular fracture, sternal fracture, spinal fracture, multiple rib fracture, pneumothorax, lung contusion, and pelvic fracture), severity of injury [injury severity score (ISS) and abbreviated injury scale (AIS) score for the chest], location and number of rib fractures, vital signs at admission (body temperature, heart rate, respiration, systolic blood pressure, diastolic blood pressure), and clinical test indices [white blood cells (WBC), hemoglobin (Hb), platelets (PLT), total protein (TP), albumin (ALB), C-reactive protein (CRP), procalcitonin (PCT), fibrinogen (FIB), fibrin degradation product (FDP), D-dimer (D-D), aspartate transaminase (AST), alanine transferase (ALT), and creatinine (Cr)]. Univariate analysis was conducted to assess the correlation between the forementioned factors and the development of delayed pleural effusion after multiple traumas. Multivariate Logistic regression analysis was used to determine the independent risk factors for the development of delayed pleural effusion after multiple traumas. Results:The results of univariate analysis showed that multiple rib fracture, pneumothorax, pulmonary contusion, chest AIS score, posterior rib fracture, number of rib fractures, TP, ALB, CRP, PCT and FDP were correlated with delayed pleural effusion in multiple trauma patients ( P<0.05 or 0.01); whereas gender, age, underlying disease, cause of injury, sternal fracture, spinal fracture, clavicular fracture, scapular fracture, pelvic fracture, maxillofacial fracture, traumatic brain injury, anterior rib fracture, ISS, vital signs at admission, WBC, Hb, PLT, FIB, D-D, AST, ALT, and Cr were not correlated with delayed pleural effusion in multiple trauma patients ( P>0.05). The results of multivariate Logistic regression analysis revealed that lung contusion ( OR=3.96, 95% CI 1.59, 9.85, P<0.01), ALB ( OR=0.79, 95% CI 0.66, 0.94, P<0.01), and CRP ( OR=1.02, 95% CI 1.01, 1.03, P<0.01) were significantly correlated with delayed pleural effusion in multiple trauma patients. Conclusion:Lung contusion, ALB, and CRP are the independent risk factors for delayed pleural effusion in multiple trauma patients.

Objective:To investigate the correlation between systemic immune inflammatory index (SII) and other metabolic indicators and diabetic epiretinal membranes (dERM).Methods:A retrospective case-control study. From March 2022 to July 2023, 81 patients (81 eyes) with dERM in Department of Ophthalmology, Affiliated Jinhua Hospital of Zhejiang University of Medicine School diagnosed by fundus screening were included in the study. A total of 81 patients (81 eyes) with diabetes who were matched in age, gender, and duration of diabetes and had no dERM or diabetic macular edema in both eyes during fundus screening were selected as the control group. All patients underwent optical coherence tomography (OCT) examination and laboratory tests for peripheral blood neutrophil, lymphocyte, platelet counts, serum albumin, blood lipids, uric acid, and glycosylated hemoglobin (HbA1c). SII was calculated. Random urine samples were collected for urinary albumin/creatinine ratio (ACR) testing. The OCT device's own analysis software obtained the macular volume coefficient, including central foveal thickness (CMT), macular volume, and average macular thickness. The macular volume coefficient, SII, serum albumin, blood lipids, uric acid, HbA1c, and ACR between the two groups were compared using paired t tests or Mann-Whitney U tests. Conditional logistic regression analysis was performed to evaluate the risk factors for dERM; Spearman correlation test was used to analyze the correlation between CMT, SII, ACR, disorganization of retinal inner layers (DRIL), intraretinal cyst (IRC), and hyper-reflective foci (HRF) in patients with dERM. Results:There were significant differences in CMT, macular volume, average macular thickness, SII, serum albumin, and ACR between the dERM group and the control group ( Z=-7.234, -6.306, -6.400, -3.063, -2.631, -3.868; P<0.05). Conditional logistics regression analysis showed that high SII [odds ratio (OR)= 3.919, 95% confidence interval ( CI) 1.591-9.654, P=0.003] and ACR ( OR=4.432, 95% CI 1.885-10.420, P=0.001) were risk factors for dERM. Spearman correlation analysis showed that HRF, IRC, DRIL were positively correlated with CMT ( Rs=0.234, 0.330, 0.248; P=0.036, 0.003, 0.026); HRF was positively correlated with SII and ACR ( Rs=0.233, 0.278; P=0.036, 0.012). Conclusion:Elevated SII and ACR are independent risk factors for the occurrence of dERM.

Objective:To evaluate the application value of extended latissimusdorsi musculocutaneous flap combined with breast precision hand in stage Ⅰ breast reconstruction.Methods:Twelve cases of extended latissimusdorsi musculocutaneous flap combined with stage Ⅰ breast reconstruction for breast cancer precision surgery were collected from January 2022 to February 2023 in our department, the postoperative complications of surgical techniques were analyzed, and the cosmetic effects of breast reconstruction were evaluated according to Harris standards.Results:All 12 cases underwent breast reconstruction with extended latissimusdorsi musculocutaneous flap, and the survival rate of the flap was 100%.

Harris evaluation of cosmetic effect of breast reconstruction was excellent in 3 cases, good in 6 cases, and fair in 3 cases. Follow-up time was 4-16 months (median was 12 months), and no local recurrence or distant metastasis was observed during follow-up.Conclusions:The extended latissimusdorsi musculocutaneous flap combined with precision mastectomy stage Ⅰ reconstruction is a safe and feasible treatment method for breast cancer.

OBJECTIVE To analyze the clinical characteristics of nephrotic syndrome induced by sunitinib， and to provide reference for clinical rational drug use. METHODS Retrieved from CNKI， VIP， Wanfang data， PubMed， Web of Science and Medline， case report about sunitinib-induced nephrotic syndrome were collected from the inception to Oct. 30th， 2022. Those case reports were analyzed statistically in terms of gender， age， primary disease， drug use， clinical manifestations， treatment and outcome. RESULTS A total of 15 pieces of literature were collected and 17 patients were involved， including 10 males and 7 females. The average age of patients was （59.35±15.72） years. Among 17 patients， there were 10 patients with renal cell carcinoma and 7 patients with gastrointestinal stromal tumor， all of whom received evidence-based medication； the dosage of sunitinib in 15 cases was recorded， and all of them were within the recommended range of the instructions； 9 patients received combined therapy； the time from sunitinib application to the occurrence of nephrotic syndrome was 21 days-52 months， of which 11 cases were ≤2 years. The clinical manifestations in 13 patients were described， including edema， oliguria， foamy urine， weight gain， fatigue， dyspnea on exertion， etc. Eight patients had other adverse reactions induced by sunitinib before suffering from nephrotic syndrome， including new hypertension or worsening of original hypertension， and hand-foot syndrome. Renal biopsy mainly manifested as thrombotic microangiopathy， focal segmental glomerular sclerosis and immune complex glomerulonephritis. Sunitinib withdrawal or dosage reduction was adopted in all patients， and they were given symptomatic treatment such as glucocorticoids and antihypertensive agents. Symptoms of 16 patients were improved， and renal function of one patient deteriorated and hemodialysis was started. Sunitinib was re-challenged in 6 patients， elevated creatinine and substantial proteinuria recurred in 5 patients. CONCLUSIONS In clinical use of sunitinib， it is advisable to periodically monitor renal function. In case of deterioration of renal function， albuminuria， edema， etc.， relevant examinations should be implemented in time， and symptomatic intervention should be taken as soon as possible. Besides， we should be alert to the recurrence of nephrotic syndrome after sunitinib rechallenge.

ObjectiveTo investigate the regulatory effect and molecular mechanism of berberine （BBR） on lipophagy in the prevention and treatment of atherosclerotic （AS） lesions in mice. MethodFifty apolipoprotein E-knockout （ApoE^-/-） mice were randomly divided into an AS model group， an atorvastatin group （5 mg·kg^-1）， and low-， medium-， and high-dose BBR groups （2.5， 5， 10 mg·kg^-1）. Ten C57BL/6J mice were assigned to the control group. After 12 weeks， hematoxylin-eosin （HE） and oil red O staining were performed to assess the histopathological changes of AS plaques in the aorta. Biochemical analysis was used to measure serum lipid levels， and enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of inflammatory cytokines interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α）， oxidative stress marker reactive oxygen species （ROS）， and serum lipophagy marker Beclin1 and microtubule-associated protein 1 light chain 3 Ⅱ （LC3Ⅱ）. The xanthine oxidase method was used to measure serum superoxide dismutase （SOD） activity. Immunohistochemistry （IHC） was used to detect the distribution of wingless-type MMTV integration site family member 5a （Wnt5a） and Nieman Pick type C1 （NPC1） in the aorta， and Western blot was used to determine the protein expression of Wnt5a and NPC1 in the aorta. ResultCompared with the control group， the AS model group showed significant AS plaque formation， significantly elevated levels of serum total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C）， IL-6， TNF-α， and ROS， aortic Wnt5a distribution and protein expression （P<0.01）， and significantly reduced levels of serum high-density lipoprotein cholesterol （HDL-C）， SOD， Beclin1， LC3Ⅱ， and aortic NPC1 distribution and protein expression （P<0.01）. Compared with the AS model group， the atorvastatin group， and high- and medium-dose BBR groups showed a significant reduction in AS plaque area （P<0.05， P<0.01）， significantly decreased levels of serum TC， TG， LDL-C， IL-6， TNF-α， ROS， and aortic Wnt5a distribution and protein expression （P<0.05， P<0.01）， and significantly increased levels of serum HDL-C， SOD， Beclin1， LC3Ⅱ， and aortic NPC1 distribution and protein expression （P<0.05， P<0.01）. There was no statistically significant difference in the above indicators between the atorvastatin group and the medium-dose BBR group. ConclusionBBR can competitively bind to Wnt5a to activate NPC1 expression， upregulate lipophagy levels， reduce blood lipids， and inhibit the release of inflammatory mediators and oxidative stress damage， thereby exerting a preventive and therapeutic effect on AS.

OBJECTIVE To analyze the clinical characteristics of liraglutide-induced pancreatitis， and to provide reference for clinical rational drug use. METHODS Retrieved from CNKI， VIP， Wanfang database， PubMed， Web of Science and Medline， case reports about liraglutide-induced pancreatitis were collected from the inception to December 31st， 2022. Demographic characteristics， drug use， clinical manifestations， intervention and outcome were analyzed using descriptive statistical method. RESULTS A total of 17 pieces of literature were collected and 17 patients were involved， including 7 males and 10 females. The patients aged from 25 to 75 years. All 17 patients had drug indications， including 14 cases of type 2 diabetes mellitus， 3 cases of obesity or overweight. Among 17 patients， liraglutide was used alone in 5 cases， and combined with other drugs in 12 cases. Time from liraglutide administration to pancreatitis occurrence ranged from 1 day to 11 months after medication in 17 patients， with 14 cases less than 6 months. The clinical manifestations mainly included abdominal pain， nausea and vomiting， etc. After the diagnosis of pancreatitis， liraglutide discontinuation occurred in 16 patients； 1 case did not receive any other interventions and the other 15 cases were managed with symptomatic supportive treatment； the symptoms of all 16 patients resolved； however， 2 patients suffered from second episode of severe pancreatitis several weeks after liraglutide discontinuation， pancreatitis recurred after liraglutide rechallenge in 1 case. The results of correlation evaluation showed that 1 case was “positive”， 4 cases were “possible”， and the remaining patients were “very likely”. CONCLUSIONS Liraglutide-induced pancreatitis mainly occurred within 6 months after drug administration. The majority of liraglutide-induced pancreatitis cases are mild to moderate， but there are also severe and even fatal cases. It is advisable to periodically monitor the level of pancreatic enzymes and closely observe patients’ clinical mani-festations. In case of suspected liraglutide-induced pancreatitis，drug withdrawal and symptomatic treatment should be taken immediately.

Objective:To analyze the clinical characteristics of patients with acute glyphosate herbicide poisoning and the differences in the severity of poisoning.Methods:A retrospective analysis was performed on patients with acute glyphosate herbicide poisoning admitted to the First Affiliated Hospital of Zhengzhou University from January 2014 to December 2020. The general information, exposure time, poisoning dose, poisoning cause, poisoning route, clinical manifestations, laboratory examination results during hospitalization, treatment measures, hospital stays and prognosis of the patients were collected. The patients were graded according to the poisoning severity scoring standard of Chinese Expert Consensus on Diagnosis and Treatment of Acute Poisoning in 2016. The highest severity score during hospitalization was used as the final grade. According to the final grade, asymptomatic and mild patients were included in the mild group, and moderate, severe and death patients were included in the severe group. The independent sample T test or Mann-Whitney U test was used for measurement data, and χ2 test or Fisher's exact test was used for counting data. The differences of general data and clinical data between the two groups were compared. Results:According to the inclusion and exclusion criteria, 83 patients with acute glyphosate herbicide poisoning were selected as the study subjects. All patients survived, mainly mild poisoning (56.6%), with a male to female ratio of 33∶50, and an average age of 39 years. The number of poisoning cases increased yearly (the highest in 2019), and most cases occurred in spring and summer. The main cause of poisoning was suicide (71.1%), direct oral administration (83.1%) was the primary route of poisoning, and the dominating clinical manifestations were digestive symptoms (71.1%). Laboratory tests showed increased white blood cell count (WBC), neutrophil percentage (NEUT %) and D-dimer, and decreased hemoglobin and potassium. Compared with the mild group, patients in the severe group were older [(51±17) years vs. (35±19) years], had a higher proportion of suicide and direct oral administration, a longer hospital stay [8.0 (4.8, 12.0) d vs. 3.0 (2.0, 5.5) d], a higher dose of poisoning [200.0 (50.0, 200.0) mL vs. 30.0 (11.3, 57.5) mL], and higher NEUT % within 24 h of admission [(83.4±10.4) vs. (73.2±12.8)]. The increase of WBC, NEUT %, aspartate aminotransferase, prothrombin time, D-dimer and the decrease of serum potassium were more common in the severe group than the mild group, with statistical significance (all P<0.05). Conclusions:The number of patients with acute glyphosate herbicide poisoning is increasing yearly. Generally, the condition is mild and the prognosis is satisfying. The severity is more serious in the middle-aged and elderly patients andthose with direct oral administration, high toxic dose, and high NEUT % within 24 h of admission. Severe poisoning is more likely to cause changes in laboratory indicators.

Objective:To study the experience of frontline medical workers in COVID-19 quarantine points.Methods:Purposive sampling method was employed and 12 frontline medical workers in COVID-19 points of Zhaoyuan City were selected for semi-structured and in-depth interview. Colaizzi′s seven-step analysis method was adopted to analyze and categorize the data.Results:The real experience of frontline medical workers in quarantine points were classified into five themes: professional mission and pride, inadequate initial response in dealing with public health emergencies (shortage of personal protective equipment,inadequate preparation of medical workers and imperfect settings of quarantine points), having some negative emotions (worrying about being infected and feeling fearful for family members), facing complex and diverse working difficulties (repugnance and diversified demands of people quarantined, heavy workload, discomfort from personal protective equipment and occupational exposure), and gaining support and appreciation (getting support from epidemic control and prevention departments as well as medical systems and winning appreciation from people quarantined).Conclusions:The frontline medical workers are lack of experience in dealing with public health emergencies and have some psychological and working pressure. Administrative department should further complete the emergency plan of centralized isolation medical observation, strengthen the contingency management of public health emergencies, attach importance to the mental health of medical workers, optimize management methods and establish flexible work schedules.

Objective:To investigated the correlation between vascular remodeling pattern and perforator stroke after stenting in patients with symptomatic intracranial vertebrobasilar artery stenosis.Methods:Patients with symptomatic intracranial vertebrobasilar atherosclerotic stenosis underwent stenting and high resolution magnetic resonance imaging (HR-MRI) from January 2017 to August 2020 were enrolled retrospectively. The data of demography, vascular risk factors, plaque characteristics, operation process and postoperative complications were collected. The plaque characteristics were observed by HR-MRI, and the correlation between vascular remodeling pattern and perforator stroke after stenting was analyzed.Results:A total of 41 patients were enrolled in the analysis. Their age was 60.1±8.8 years (range, 49-77 years). There were 31 males (75.6%). Among them, 21 (51.2%) were positive remodeling, 20 (48.8%) were non-positive remodeling, and 5 (12.2%) had perforator stroke after procedure. The incidence of perforator stroke in the positive remodeling group was significantly higher than that in the non-positive remodeling group (23.8% vs. 0%; P=0.048). The positive remodeling rate of the perforator stroke group was significantly higher than that of the non-perforator stroke group (100.0% vs. 44.4%; P=0.048). Conclusions:Patients with intracranial vertebrobasilar atherosclerotic stenosis and positive vascular remodeling were more likely to have perforator stroke after stenting.
