OBJECTIVE To investigate the role of clinical pharmacists in the individualized treatment of a rare case of diffuse pulmonary microabscesses caused by Streptococcus constellatus complicated with organizing pneumonia （OP） in a non-immunocompromised patient. METHODS For a middle-aged， non-immunocompromised patient with a one-year disease course， whose imaging findings showed the coexistence of diffuse microabscesses and OP caused by S. constellatus pulmonary abscess， the clinical pharmacist， based on pharmacokinetics/pharmacodynamics characteristics， assisted the physician in optimizing the previously ineffective anti-infective regimen to Ceftriaxone sodium for injection combined with Metronidazole and sodium chloride injection， so as to enhance coverage of mixed anaerobes and lesion penetration. After the patient’s hemoptysis ceased， the clinical pharmacist recommended timely initiation of low-dose Methylprednisolone sodium succinate for injection to manage OP. Upon discharge， sequential oral therapy with Linezolid tablets， Metronidazole tablets， Methylprednisolone tablets and Omeprazole enteric-coated tablets was prescribed. RESULTS After implementation of the individualized treatment regimen， the patient’s hemoptysis resolved， pulmonary lesions significantly regressed， and the patient was discharged in a stable condition. At the three-month follow-up， the patient remained stable. CONCLUSIONS For chronic persistent pulmonary infection complicated with OP in a non-immunocompromised host， clinical pharmacists assist clinicians in optimizing anti-infective regimens and recommend the timely initiation of anti-inflammatory therapy after infection control， thereby contributing to favorable clinical outcomes. Individualized treatment of such complex cases requires comprehensive consideration of pathogen coverage， pathological barriers， and the timing of anti-inflammatory intervention.

ObjectiveTo establish a regional risk assessment system for hospital-acquired infections in neurosurgery department of general hospital, and to evaluate its prevention and control effectiveness. MethodsFailure mode and effect analysis (FMEA) was used to identify the core risk factors for infections in neurosurgery department. The risk priority number (RPN) of each risk factor was calculated to determine the priority intervention targets. Targeted interventions were developed and continuously refined through the plan-do-check-act (PDCA) cycles. Data from January to June 2023 (control group) and July to December 2023 (intervention group) were collected to compare the differences in environmental hygiene monitoring qualification rate, incidence rate of hospital-acquired infections among inpatients, and detection rate of bacterial antimicrobial resistance. ResultsHigh-risk factors for hospital-acquired infections in neurosurgery department included patient-related risk factors, inadequate implementation of isolation measures for special infections, and poor compliance with surgical site infection (SSI) prevention protocols. After intervention, the environmental hygiene qualification rate significantly increased from 81.55% to 100.00% (χ²=120.49, P<0.001). The overall hospital-acquired infection rate among inpatients decreased from 2.62% to 2.45%, the infection rate of per case declined from 3.12% to 2.84%, and the detection rate of multidrug-resistant organism infections reduced from 43.72% to 36.79%. Additionally, antimicrobial utilization rate decreased from 48.75% to 42.53% (χ²=34.09, P<0.001). ConclusionThe FMEA-based risk assessment system can effectively identify critical infection risks in neurosurgery department, and targeted interventions can significantly improve infection prevention and control performance.

OBJECTIVE To investigate the apoptosis-inducing effect of esculetin （Esc） on acute myeloid leukemia （AML） HL-60 cells by regulating the protein kinase B （AKT）/S-phase kinase-associated protein 2 （SKP2）/MutT homolog 1 （MTH1） pathway. METHODS AML HL-60 cells were randomly divided into control group （routine culture）， Esc low-concentration group （L-Esc group， 25 μmol/L Esc）， Esc medium-concentration group （M-Esc group， 50 μmol/L Esc）， Esc high-concentration group （H-Esc group， 100 μmol/L Esc）， and high-concentration of Esc+ SC79 （AKT agonist） group （100 μmol/L Esc+5 μmol/L SC79）. Cell proliferation in each group was detected by MTT assay and colony formation assay. The level of reactive oxygen species （ROS） in cells was measured by using the CM-H2DCFDA fluorescent probe. Cell apoptosis was analyzed by flow cytometry. Western blot assay was performed to detect the expression levels of apoptosis-related proteins [B-cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cleaved caspase-3]， AKT/SKP2/MTH1 pathway-related proteins （p-AKT， AKT， SKP2， MTH1）， along with the upstream and downstream proteins of AKT phosphatidylinositol 3-kinase （PI3K）， cyclin-dependent kinase inhibitor 1 （P21） and cyclin-dependent kinase inhibitor 1B （P27）. RESULTS Compared with control group， the cell viability， colony number， and the phosphorylation levels of AKT and PI3K proteins as well as protein expressions of SKP2， MTH1 and Bcl-2 were significantly decreased （P＜0.05）， while ROS level， apoptosis rate， and the expression levels of Bax， cleaved caspase-3， P21 and P27 proteins were significantly increased （P＜0.05）. Moreover， the effects of Esc exhibited concentration-dependence （P＜0.05）. Compared with H-Esc group， above indexes of high-concentration of Esc+ SC79 group were reversed significantly （P＜0.05）. CONCLUSIONS Esc may promote massive ROS production and induce activation of apoptosis in HL-60 cells by inhibiting the AKT/SKP2/MTH1 pathway， thus inhibiting the proliferation of HL-60 cells.

Objective To analyze the postoperative complications and survival outcomes of elderly patients with renal cell carcinoma undergoing laparoscopic surgery, and to identify the influencing factors, so as to provide reference for improving the safety of laparoscopic surgery in such patients. Methods A retrospective analysis was conducted on the clinical, surgical, and pathological data of 153 patients aged ≥75 years who underwent laparoscopic nephrectomy for renal cell carcinoma at our hospital during 2012 and 2025.Logistic regression analyses were performed to identify factors influencing postoperative complications, and a nomogram was constructed and validated to predict the complications.Kaplan-Meier method was used to draw the survival curve, and the effects of different surgical approaches on the prognosis and the survival difference in the age subgroups (75-＜80 years, ≥80 years) were analyzed.Cox regression analyses were conducted to determine factors affecting survival outcomes. Results Among the 153 patients, 15 developed postoperative complications, including 5 severe cases. Multivariate logistic regression identified Charlson Comorbidity Index (CCI) ≥3 and prolonged operation time as independent risk factors for postoperative complications (P＜0.05).The C-index of the logistic regression model constructed based on these factors (age, CCI≥3 and operation time) was 0.77 (95%CI:0.64-0.90), with an average absolute error of 1.6%.Subgroup analysis revealed superior overall survival in patients aged 75-＜80 years undergoing partial nephrectomy compared to radical nephrectomy (P=0.005 6).No statistically significant difference in overall survival was observed among patients ≥80 years who received different surgical approaches (P=0.062).Multivariate Cox regression analysis identified preoperative low albumin levels, preoperative renal insufficiency, tumor diameter＞4 cm, and pathological stage as independent risk factors for overall survival (P＜0.05). Conclusion Laparoscopic surgery is safe and effective for elderly patients with renal cell carcinoma, with survival outcomes correlated to nutritional status, renal function, tumor size and pathological staging.Patients aged ≥80 years still derive surgical benefit, and no survival differences exist between different surgical approaches in this age group.

Objective: To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures. Methods: Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC). Results: A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively. Conclusions The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

Hepatocellular carcinoma （HCC） is a common malignant tumor with a high mortality rate， an insidious onset， and complex pathological mechanisms. In the tumor microenvironment， tumor-promoting immune cells protect tumor cells from immune attacks， while dysfunction of anti-tumor immune cells causes the inhibition of immune response， thereby leading to the continuous deterioration of cancer. In recent years， traditional Chinese medicine has shown good efficacy in the treatment of HCC， and it can inhibit the proliferation and metastasis of cancer cells by regulating immune cells. By analyzing related articles in China and globally， this article summarizes how immune cells affect the progression of HCC through the immunosuppressive pathway and how traditional Chinese medicine exerts an anti-HCC effect by regulating immune cells， in order to provide theoretical basis and reference for optimizing the treatment of HCC.

[Objective] To explore the diagnosis and treatment experience of tension hydrocele. [Methods] The clinical data of 2 patients with tension hydrocele treated in our hospital were retrospectively analyzed.Relevant literature was retrieved to analyze the clinical characteristics of this disease. [Results] Case 1 was diagnosed due to swelling and pain of the left scrotum after trauma for more than one month, which worsened for one day.Physical examination showed high tension in the left scrotum and positive light transmission test.Ultrasound examination revealed that the blood flow signal in the left testis disappeared.Emergency left scrotal exploration and hydrocelectomy were performed.There was no sign of testis torsion during the operation.Case 2 was diagnosed mainly due to hydrocele of the right testis for 1 year, which worsened for 1 week and complicated with testis distension and pain.Physical examination showed high tension in the right scrotum and positive light transmission test.Ultrasound examination revealed that the blood flow signal in the right testis decreased.After 40ml of fluid was extracted under ultrasound monitoring, the blood flow signal in the right testis recovered.Hydrocelectomy was performed the next day.During the follow-up of 8 months, there was no recurrence of hydrocele.A search of domestic and foreign literature showed that there were no reports in domestic literature, while a total of 11 cases were reported in foreign literature. [Conclusion] Tension hydrocele of the testis is a rare emergency of the scrotum.Surgery or decompression should be performed as soon as possible to restore testicular blood supply, and hydrocelectomy should be performed simultaneously or in stages to prevent recurrence.

Objective To screen the differential expression profile of circ_RNA in OSCC and to elucidate the molecular mechanism of circ_PVT1 on OSCC carcinogenesis.Methods The transcripts of 3 cases of OSCC and normal tissues were sequenced by high-throughput sequencing using circ_RNA expression profile chip,and the differential gene expression profiles were screened,and GO and KEGG enrichment analysis were performed.The expression level of PVT1 in OSCC tissues,human normal oral mucosal cells and OSCC cells was detected by qRT-PCR.The effect of PVT1 on the biological behavior of SCC-25 and SCC-9 cells was evaluated by MTT exper-iment,Transwell experiment and flow cytometry.The effect of PVT1 on the expression of key proteins in the Wnt3a/β-catenin pathway was evaluated by Western blot.The relationship between the expression of PVT1 and clinical pathological characteristics and prognosis of patients was further studied.Results A total of 403 differentially expressed circ_RNAs were screened by the chip,and the differen-tially expressed genes were enriched in pathways related to cancer progression.PVT1 was highly expressed in OSCC tissues and cells.Silencing PVT1 expression could inhibit the activation of the Wnt3a/β-catenin pathway,thereby effectively inhibiting the proliferation,migration,invasion and cell cycle of SCC-25 and SCC-9 cells and promoting apoptosis.PVT1 expression was only associated with lymph node metastasis and distant metastasis in patients,and those with high expression had a shorter PFS.Conclusion PVT1 promotes the progression of OSCC by regulating the activation of Wnt3a/β-catenin pathway.The research results provide new ideas for the diagnosis and treatment of OSCC.
