Objective:To evaluate the safety of neoadjuvant therapy with pembrolizumab combined with 5-fluorouracil (5-FU) and cisplatin in patients with advanced temporal bone squamous cell carcinoma (TBSCC), and its impact on tumor response rate and disease-free survival (DFS).Methods:This prospective, single-arm, open-label clinical study enrolled patients with advanced (Stage Ⅲ/Ⅳ) TBSCC from Sun Yat-sen Memorial Hospital. Patients received 2-3 cycles of neoadjuvant therapy with pembrolizumab, 5-FU, and cisplatin, followed by definitive surgery. Postoperatively, patients received 6 cycles of pembrolizumab combined with radiotherapy. The primary endpoint was the 2-year disease-free survival (DFS) rate. Secondary endpoints included objective response rate (ORR) and safety indicators. Survival analysis was performed using the Kaplan-Meier method. Adverse events (AE) were assessed using the National Cancer Institute′s Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Statistical analyses were conducted using SPSS software, version 22.0.Results:From August 2021 to April 2024, 16 patients with advanced TBSCC were enrolled (13 males and 3 females), with a median age of 54 years and a median follow-up time of 2.32 years. Following neoadjuvant therapy, the objective response rate (ORR) was 64.3% (9/14), and the disease control rate (DCR) was 92.9% (13/14). The 2-year DFS rate was 86.6%. Common treatment-related adverse events (TRAE) included leukopenia (56.3%, 9/16), nausea and vomiting (50.0%, 8/16), diarrhea, oral mucositis, and elevated liver function tests (25.0%, 4/16). One patient (6.25%) experienced a grade 3 adverse event.Conclusion:Neoadjuvant pembrolizumab-chemotherapy significantly enhances objective response rate and disease-free survival in advanced TBSCC.

Objective To explore the feasibility and safety of ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer.Methods Totally 84 patients who underwent ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer were enrolled,and the technical success rate,complete ablation rate,complication rate,pain relief rate and survival time,etc.were observed.Results The median age of 84 cases was 61.5 years.Totally 86 tumors,including 44.19％(38/86)at the head/neck and 55.81％(48/86)at the body/tail of pancreas were detected,and a total of 85 ablation sessions were performed with the median ablation energy applied per tumor of 9.90(1.08,21.60)kJ and the complete ablation rate of 42.86％(36/84).The technical success rate was 100％(85/85).Thirty-nine complication events occurred in 25 cases,no ablation-related death.Among 34 patients underwent ablation mainly for pain symptoms,the pain score decreased from(6.22±1.12)points before treatment to(1.94±1.64)points after treatment(P＜0.001).During 6.8(3.3,12.9)months' follow-up,the mean survival time was(8.5±6.7)months,and all 47 patients died due to tumor progression.Conclusion Ultrasound-guided percutaneous microwave ablation was safe and feasible for unresectable pancreatic cancer.

Objective:To investigate the clinical characteristics of children with Chikungunya fever.Methods:This retrospective cohort study analyzed clinical data of 91 children with Chikungunya fever at the Department of Pediatrics, Foshan women and Children Hospital between July 2025 and August 2025. The patients were divided into four groups based on onset-age: 0-<1 year, 1-<3 years, 3-<6 years, and 6-14 years. One-way ANOVA and chi-square tests were used to compare the clinical features of children with Chikungunya fever at different ages.Results:Among the 91 children with chikungunya fever, 55 were male and 36 were female, with an onset age of 6 (2, 11) years, age groups comprised 0-<1 year (10 cases), 1-<3 years (13 cases), 3-<6 years (17 cases) and 6-14 years (51 cases). Fever occurred in 87 cases (96%), with 50 cases (57%) had high fever. Skin rash was observed in 89 cases (98%), and 60 cases (67%) had a generalized rash. Joint pain was reported in 57 cases (63%), among which 35 cases (61%) had pain in two or more locations, with the knee involved in 21 cases (37%), the ankle in 15 cases (26%), and the wrist in 6 cases (11%).The knee was the most commonly affected joint 21 cases (37%), followed by the ankle 15 cases (26%) and wrist 6 cases (10%). Joint ultrasound was performed in 31 cases (34%), all showed joint effusion, including 8 cases (26%) without complaints of joint pain. The incidence of high fever was significantly lower in the 3-<6 years and 6-14 years groups compared to the 0-<1 year group (both P<0.05). The 6-14 years group also had a lower incidence of high fever than the 1-<3 years group ( P<0.05). The 1-<3 years group had longer duration of fever than the 3-<6 years and 6-14 years groups (both P<0.05). The incidence of joint pain was higher in the 3-<6 years and 6-14 years groups compared to the 1-<3 years group (both P<0.05), and higher in the 6-14 years group than in the 3-<6 years group ( P=0.007). Among all 91 children, 22 cases (24%) had abnormal liver function, 49 cases (54%) showed elevated lactate dehydrogenase (LDH), and 2 cases (2%) had elevated creatine kinase. The proportions of elevated aspartate aminotransferase (AST) and LDH were higher in the 0-<1 year and 1-<3 years groups compared to the 3-<6 years and 6-14 years groups (all P<0.05). Conclusions:The clinical characteristics of children with Chikungunya fever vary among children of different ages. Children in the 0-<3 years are more prone to high fever with longer duration and generalized maculopapular rash, while the children in the 6-14 years have have a higher proportion of joint pain, and joint ultrasound revealed effusion in all examined children. AST and LDH levels are elevated in the 0-<3 years groups.

Objective To explore the effects of evidence-based nursing combined with multi-dimensional health education on negative emotions and postoperative rehabilitation of patients undergoing elective surgery for cholecystolithiasis.Methods A total of 100 patients with cholecystolithiasis who underwent elective surgery in Yixing Traditional Chinese Hospital Medicine from September 2023 to August 2024 were selected.The patients were assigned to control group and observation group by PEMS3.1 for Windows completely random(two groups and multiple groups)program,with 50 cases in each group.The control group received routine nursing,and the observation group received evidence-based nursing combined with multidimensional health education on the basis of routine nursing.The intervention duration of the two groups was 7 days.Visual analogue scale(VAS)scores,negative emotions(self-rating anxiety scale[SAS]and self-rating depression scale[SDS]),postoperative complications,and postoperative rehabilitation were compared between the two groups.Results The VAS scores at 24 h and 72 h after surgery were lower than those at 6 h after surgery in both groups,especially in the observation group(P<0.05).The scores of SAS and SDS in both groups after intervention were significantly decreased compared with those before intervention,and the scores of negative emotions in the observation group after intervention were significantly lower than those in the control group(P<0.05).The total incidence of gastrointestinal discomfort,biliary fistula and wound infection/bleeding in the observation group was significantly lower than that in the control group(4.00%vs.18.00%,P<0.05).The time of getting out of bed,the time of anal exhaust,the time of resuming normal diet and the time of hospitalization in the observation group were significantly lower than those in the control group(P<0.05).Conclusion The combination of evidence-based nursing and multi-dimensional health education during perioperative period of cholecystolithiasis surgery can reduce postoperative pain,improve the positive attitude of treatment,reduce complications,and promote the recovery of the disease.

Objective To explore the mechanism of Yishen Jiangtang Decoction(YSJTD)in improving diabetic kidney disease(DKD)based on the apoptotic Bcl-2/Caspase-3 pathway mediated by endoplasmic reticulum stress(ERS).Methods Thirty 8-week-old SPF male db/db mice were used to establish the DKD model and were randomly divided into model,YSJTD,ERS inhibitor(4-phenylbutyric acid[4-PBA]),and control groups(db/m mice),with 10 mice per group.Mice in the YSJTD and 4-PBA groups were gavaged daily with 5.6 mg/(g·d)YSJTD or 0.5 mg/(g·d)4-PBA,respectively,whereas the model and control groups received sodium carboxymethyl cellulose.Each mouse was orally administered 0.01 mL/(g·d)for 8 weeks.The mice were administered 0.01 mL/(g·d)YSJTD or 0.5mg/(g·d)4-PBA via gavage for 8 weeks.The general condition of the mice was observed,and blood glucose and plasma lipid levels were measured.Oral glucose tolerance tests(OGTT)and insulin tolerance tests(ITT)were performed,and the area under the curve(AUC)was calculated.Renal pathological changes(assessed using hematoxylin and eosin,periodic acid-Schiff,and Masson staining)and cell apoptosis,evaluated via TUNEL staining,were examined.Protein expression levels of Caspase-3 and Bcl-2 in kidney tissues were analyzed using Western blotting.A DKD model was established using high-glucose-induced mouse glomerular mesangial cells,SV40 MES 13.The Cell Counting Kit-8 assay was used to screen for high glucose concentrations and to determine the concentration of the YSJTD drug-containing serum.Cells were divided into four groups:control,model(30 mmol/L high glucose),10％YSJTD drug-containing serum(30 mmol/L high glucose+10％drug-containing serum),and 1 mol/L 4-PBA(30 mmol/L high glucose+1 mmol/L 4-PBA).Western blotting was used to detect the protein levels of GRP78,Caspase-3,and Bcl-2 in the cells.Results Compared to the control group,the model,YSJTD,and 4-PBA groups exhibited significantly increased OGTT-AUC,ITT-AUC,triglyceride(TG),and cholesterol(CHOL)levels(P＜0.05).These groups also showed severe renal pathological damage,increased glycogen deposition,and exacerbated fibrosis in kidney tissues.Compared to the model group,both the YSJTD and 4-PBA groups showed significantly reduced OGTT-AUC,TG,and CHOL levels,alleviated renal pathological damage,and decreased glycogen deposition and fibrosis.The YSJTD group also exhibited significantly reduced ITT-AUC(P＜0.05).Compared to the control group,the model group exhibited an increased number of apoptotic cells in renal tissue,reduced Bcl-2 expression,and elevated Caspase-3 expression(P＜0.05).Compared to the model group,both the YSJTD and 4-PBA groups demonstrated a reduced number of apoptotic cells,decreased Caspase-3 expression,and increased Bcl-2 expression,with the YSJTD group showing a more pronounced decrease in apoptotic cells(P＜0.05).In vitro experiments revealed that,compared to the control group,the model group exhibited increased GRP78 and Caspase-3 expression,as well as decreased Bcl-2 expression(P＜0.05).Compared to the model group,the 10％YSJTD drug-containing serum and 1 mol/L 4-PBA groups showed reduced GRP78 and Caspase-3 expression,as well as upregulated Bcl-2 expression(P＜0.05).Conclusion YSJTD improves glucose and lipid metabolism disorders in DKD by inhibiting the ERS-induced apoptotic pathway mediated by Bcl-2/Caspase-3,thereby exerting protective effects on renal function.

Objective:To evaluate the association between septic shock and tracheal injury in the intensive care unit (ICU) patients with invasive ventilation.Methods:This was a prospective single-centre cohort study. Patients who underwent invasive mechanical ventilation at the Department of Anesthesia Critical Care Medicine of the Second Hospital of Hebei Medical University from May 31, 2020 to March 5, 2022 were selected. The general characteristics of patients, reasons for ICU admission, vital signs, laboratory test results, Acute Physiology and Chronic Health Evaluation Ⅱ scores, Charlson Comorbidity Index, size of endotracheal tube, presence or absence of septic shock, oxygenation index, duration of intubation, consumption of norepinephrine and epinephrine, and tracheal injury scores at the time of extubation were recorded. Univariate linear regression analysis was used to identify the risk factors for tracheal injury, followed by adjustment using multivariate linear regression analysis.Results:Ninety-seven patients were ultimately included, and the average age was (56.6±16.5) yr, with 64.9% being male. The results of adjusted linear regression showed that septic shock was associated with tracheal injury scores ( β=2.99, 95% confidence interval 0.70-5.29). Subgroup analysis revealed a stronger correlation with a duration of intubation≥8 days ( P=0.013). Conclusions:Patients with septic shock exhibit significantly higher tracheal injury scores compared with those without septic shock, suggesting that septic shock may serve as an independent risk factor for tracheal injury.
