Objective This study aims to explore the efficacy and complication rates of the transcranial approach(TCA)and extended endoscopic endonasal approach(EEEA)for the treatment of craniopharyngiomas based on the QST classification,providing a scientific reference for clinical decision-making on surgical approach.Methods A total of 151 patients who underwent craniopharyngioma surgery at our center from January 2018 to December 2023 were enrolled.The patients were categorized into Q-CP(suprasellar type),S-CP(infundibular type),and T-CP(tuberal type)according to the QST classification.Systematic collection and analysis were performed on the outcomes of TCA and EEEA treatments,respectively.The differences in effectiveness between the two approaches were evaluated based on the QST classification.Results The improvement rate of visual symptoms was overall higher in the EEEA group than in the TCA group(59.1%vs.36.5%,P=0.006),and the visual deterioration rate was lower(3.0%vs.14.1%,P=0.006).However,the incidence of cerebrospinal fluid leakage was higher in the EEEA group(15.2%vs.3.5%,χ2=4.986,P=0.026).The incidence of postoperative seizures(8.2%vs.0,P=0.019),brain contusions(10.6%vs.0,P=0.005),and subdural hematoma(9.4%vs.0%,P=0.01)was higher in the TCA group.For patients with Q-CP type,the EEEA group had a higher rate of total tumor resection(92.9%vs.65.2%,P=0.025)and a lower recurrence rate(3.6%vs.21.7%,P=0.047),with shorter hospital stays and lower postoperative costs.The TCA group had higher intraoperative blood loss in this type(300 mL vs.200 mL,Z=-2.261,P=0.024).For S-CP type patients,the EEEA group showed a higher rate of total tumor resection(91.3%vs.74.2%)and a lower recurrence rate(0 vs.12.9%,P=0.031),with lower postoperative hospital costs.In T-CP type,due to the deeper location,EEEA showed limitations in protecting hypothalamic function and the TCA group had a better postoperative hypothalamic function score(P=0.035).Conclusion Based on QST classification,EEEA has advantages in Q-CP and S-CP types and is recommended as the preferred surgical procedure;In the T-CP type,TCA surgery is more helpful in protecting hypothalamic function.

This study analyzed the epidemiological characteristics and trends of respiratory syncytial virus (RSV) infections among inpatients with acute respiratory infections (ARI) in a children′s hospital in Shenzhen City inpatients from 2020 to 2023. From January 2020 to December 2023, multiple reverse transcription polymerase chain reaction (RT-PCR) combined with capillary electrophoresis fragment analysis technology was used to detect the nucleic acids of 12 respiratory pathogens, including RSV, in hospitalized children diagnosed with ARI. The patients were divided into six age groups: 0 to <6 months, 6 months to <1 year, 1 to <2 years, 2 to <5 years, 5 to <10 years, and 10 to <18 years. A total of 53 033 children were tested, including 6 830 RSV positive cases, with an overall positivity rate of 12.88%. The annual RSV positivity rates from 2020 to 2023 were 20.04%, 16.18%, 4.89%, and 13.33%, respectively, with statistically significant differences between the years ( χ2=1 185.994, P<0.001). The positive rate of RSV detection decreased with increasing age across all years (all P trend<0.05). From 2020 to 2023, the proportion of RSV-positive cases aged 2 to 5 years and older showed an increasing trend ( P trend<0.001 for all years). Compared to 2023, the median age of RSV-infected children was lower in 2020 ( Z=7.826, P<0.001) and 2021 ( Z=6.106, P<0.001). The proportion of severe infections requiring ICU admission did not change significantly across all years ( χ2=0.179, P=0.981). The RSV epidemic season in 2020 mainly occurred during 28-43 weeks, and in 2021, it spanned from 22-43 weeks. However, in 2022, the season was delayed until the 49th week and lasted for three weeks. In 2023, the seasonal epidemic appeared earlier, starting in the 14th week and lasting for 28 weeks. From 2020 to 2023, the rate of RSV co-infections with other pathogens (mycoplasma pneumoniae, human parainfluenza virus, human bocavirus, human coronavirus, human metapneumovirus, and influenza A) significantly increased (all P trend<0.01). In conclusion, the epidemiological characteristics of RSV infections in Shenzhen Children′s Hospital changed from 2020 to 2023. In 2022, there were only delayed, low-intensity and short-lived seasonal epidemics. However, in 2023, there was an earlier and prolonged epidemic, with increased infections in children aged 2 to 5 years and older and a rise in co-infections, while the proportion of severe infections requiring ICU admission remained unchanged.

Objective:To compare and discuss the mid-to-long-term outcomes of mitral valve repair (MVP) versus biological mitral valve replacement (bMVR) in patients aged 60 years and above with rheumatic mitral valve disease.Methods:This is a retrospective cohort study. A total of 765 patients aged 60 years and older, diagnosed with rheumatic mitral valve disease and who underwent MVP or bMVR at Beijing Anzhen Hospital from January 2010 to January 2023, were retrospectively included. Among them, 186 were male and 579 were female, with an age of (66.1±4.5) years (range: 60 to 82 years). Patients were divided into two groups based on the surgical method: the mitral valve repair group (MVP group, n=256) and the bioprosthetic mitral valve replacement group (bMVR group, n=509). A 1∶1 propensity score matching was performed using a caliper value of 0.2 based on preoperative data. Paired sample t-tests, χ2 tests, or Fisher′s exact tests were used for intergroup comparisons. Kaplan-Meier method was employed to plot survival curves and valve-related reoperation rate curves for both groups before and after matching, and Log-rank tests were used to compare the mid-to long-term survival rates and valve-related reoperation rates between the two groups. Results:A total of 765 patients who completed follow-up were ultimately included, with a follow-up period ( M(IQR)) of 5.1(5.0) years (range: 1.0 to 12.9 years). After matching, each group consisted of 256 patients. The incidence of early postoperative atrial fibrillation (39.1% vs. 49.2%, χ2=4.95, P=0.026) and early mortality rates (2.0% vs. 6.2%, χ2=4.97, P=0.026) were lower in the MVP group. Unadjusted Kaplan-Meier analysis showed significantly higher 5-year and 10-year survival rates for the MVP group (92.54% vs. 83.02%, 86.22% vs. 70.19%, Log-rank: P=0.001). After adjustment with propensity scores, the Kaplan-Meier analysis still indicated higher 5-year and 10-year survival rates in the MVP group compared to the bMVR group (92.54% vs. 85.89%, 86.22% vs. 74.83%, Log-rank: P=0.024). There were no significant differences in the rates of valve-related reoperation between the two groups before and after matching (5-year and 10-year reoperation rates pre-matching: 1.75% vs. 0.57%, 5.39% vs. 7.54%, Log-rank: P=0.207; post-matching: 1.75% vs. 0, 5.39% vs. 9.27%, Log-rank: P=0.157). Conclusion:For patients aged 60 years and above with rheumatic mitral valve disease, mitral valve repair offers better mid-to-long-term survival compared to biological valve replacement.

Objective To investigate the correlation between amide proton transfer-weighted(APTw)value derived from APTw imaging and Ki-67 expression in hepatocellular carcinoma.Methods Sixty patients with hepatic occupations underwent preoperative upper abdominal MRI scanning,including APTw and diffusion weighted imaging(DWI)sequences.Thirty-two patients with hepatocellular carcinoma proved by pathological results were enrolled in the prospective study.The APTw and apparent diffusion coefficient(ADC)values of the lesions were measured from the corresponding APTw and ADC images,respectively.Mann-Whitney U test or independent sample t test was used to analyze the differences in APTw and ADC values between the high and low Ki-67 expression groups.Pearson correlation analysis was used to evaluate the correlation between APTw value,ADC value and Ki-67 expression level of hepatocellular carcinoma.The receiver operating characteristic(ROC)curve was used to evaluate the diagnostic efficacy of amide proton transfer(APT)parameter in differentiating high and low Ki-67 expression groups.Results The APTw values of high Ki-67 expression group(n=24)was higher than that of low Ki-67 expression group(n=8)[(1.33±0.77)％vs(0.64±0.58)％,P=0.026].There was no significant difference in ADC values between the two groups(0.82×10-3 mm2/s vs 0.86×10-3 mm2/s,P=0.679).The APTw values were positively correlated with Ki-67 expression(r=0.377,P=0.035),and the area under the curve(AUC)of APTw value＞1.24％for the diagnosis of high Ki-67 expression was 0.794,with a sensitivity of 67％and a specificity of 88％.Conclusion The APTw value of hepatocellular carcinoma is positively correlated with Ki-67 expression,which has certain diagnostic value for predicting the expression status of Ki-67.

Objective To investigate the value of extracellular volume fraction(ECV)based on CT for predicting macrotrabecular-massive hepatocellular carcinoma(MTM-HCC).Methods Data of 23 MTM-HCC(MTM-HCC group)and 56 non-MTM-HCC(nMTM-HCC group)patients were retrospectively analyzed,and CT manifestations were compared between groups.CT values of abdominal aorta(P-CTabdominal aorta,E-CTabdominal aorta),tumors(P-CTtumor,E-CTtumor)and non-tumor liver parenchyma(P-CTliver,E-CTliver)in plain phase(P)and enhancement equilibrium phase(E)CT were measured,then ECV of tumors and liver parenchyma were calculated,and ECV-related parameters were compared between groups.Receiver operating characteristic curves were drawn,and area under the curve(AUC)was calculated to evaluate the predictive efficacy of ECV-related parameters for predicting MTM-HCC.Results No significant difference of CT manifestations was found between groups(all P＞0.05).E-CTtumor,Δltumor(absolute enhancement CT value of the tumor area)and ECVtumor in MTM-HCC group were all lower than those in nMTM-HCC group(all P＜0.01).The AUC of E-CTtumor,Δtumor and ECVtumor for predicting MTM-HCC was 0.74,0.77 and 0.87,respectively,and the AUC of ECVtumor was higher than that of E-CTtumor and Δtumor(Z=2.271,2.557,P=0.023,0.011).Conclusion ECV based on CT could be used to effectively predict MTM-HCC.

【Objective】 To explore the clinical features, treatment and prognosis of paraganglioma of the urinary bladder (PUB). 【Methods】 The clinical data of 41 PUB patients treated at our hospital during Sep.2012 and Sep.2022 were collected. The clinical features, surgical records, pathological reports and follow-up records were retrospectively analyzed. Patients’ survival was estimated with Kaplan-Meier estimator. The differences among groups were compared with Log-rank test. 【Results】 Among the 41 patients, 20 were male and 21 were female, with a median age of 52 years. All patients were treated with surgery, including transurethral resection of bladder tumor (TURBT) in 16 cases, partial cystectomy (PC) in 23 cases, and radical cystectomy (RC) in 2 cases. All patients were followed up for 4.0 to 125.0 months, with a median of 59.0 months. Local recurrence occurred in 5 patients, and distant metastasis occurred in 5 patients. Survival analysis showed that the 5-year overall survival (OS) rate and 5-year relapse-free survival (RFS) rate were 95.7% and 84.8%, respectively. Further analysis showed statistically significant differences in OS and RFS among groups with different maximum tumor diameters, growth patterns, and Ki-67 expressions (P<0.05). For patients with a maximum tumor diameter ≤2.8 cm, there was no significant difference in OS and RFS among different surgical groups. 【Conclusion】 PUB is rare, and a definitive diagnosis is based on pathology. In addition, the main treatment is surgery and the prognosis is good.

The clinical data of a 64-year-old patient with adrenocortical adenoma complicated with inferior vena cava tumor thrombus(IVCTT) were retrospectively analyzed. The patient was admitted becourse of intermittent dizziness for 4 months. CT examination revealed right adrenal tumor, and IVCTT was found in operation. Adrenal cortical adenoma needs to be distinguished from adrenal cortical carcinoma pathologically. Preoperative color Doppler ultrasonography, CT angiography or inferior vena cava angiography can confirm the diagnosis of IVCTT and tumor thrombus grade, and different surgical methods should be selected according to tumor thrombus grade.
