Objective To investigate the efficacy of early, short-term, low-dose corticosteroid administration for the prevention and treatment of early acute lung injury (EALI) in patients undergoing thoracoscopic lobectomy. Methods A retrospective analysis was conducted on the clinical data of patients who underwent thoracoscopic lobectomy at the Department of Thoracic and Cardiovascular Surgery, Taihe Hospital, Hubei University of Medicine, from January 2019 to January 2022. Patients were divided into an early steroid therapy group and an observation group based on whether they received corticosteroids in the early postoperative period. In the early steroid therapy group, in addition to standard postoperative care, patients received a low-dose intravenous push of methylprednisolone (80-120 mg/d) for 3 consecutive days. In the observation group, patients received standard postoperative care without intravenous corticosteroids for the first 3 days. Chest plain CT scans were performed on postoperative day (POD) 1 and POD 3 or 4 to evaluate lung injury. CT scores and the incidence of postoperative EALI were recorded. Results A total of 521 patients were included (268 males, 253 females; age range: 11-80 years). There were 318 patients in the observation group and 203 in the early steroid therapy group. On POD 1, the incidence of EALI was 16.0% in the observation group and 13.8% in the early steroid therapy group, with no statistical difference (P=0.486). Correspondingly, there was no statistical difference in chest CT scores among EALI-positive patients between the two groups (P=0.927). On POD 3-4, the incidence of EALI was significantly lower in the early steroid therapy group (22.7%) compared to the observation group (33.6%) (P=0.007). Although chest CT scores among EALI-positive patients were lower in the early steroid therapy group, the difference was not statistically significant (P=0.377). The overall incidence of EALI within the first 4 postoperative days was significantly lower in the early steroid therapy group (26.1%) than in the observation group (37.4%) (P=0.007). Radiological progression (defined as new-onset EALI or progression of existing EALI) occurred in 14.8% of the early steroid therapy group, significantly lower than the 28.9% in the observation group (P<0.001). The early steroid therapy group had a shorter postoperative length of stay (P<0.001), while there was no statistical difference in the incidence of poor wound healing between the groups (P=0.762). Conclusion Early postoperative corticosteroid use effectively reduces the incidence of EALI on POD 3-4, lowers the risk of radiological progression, and decreases the overall incidence of postoperative EALI. This is achieved without prolonging the length of stay or increasing the risk of poor wound healing. Therefore, early administration of low-dose corticosteroids is beneficial in suppressing the occurrence and progression of EALI. Its early use is recommended for patients at high risk for postoperative EALI.

Objective To systematically evaluate the efficacy and safety of video-assisted thoracoscopic surgery (VATS) with different numbers of ports in the treatment of spontaneous pneumothorax. Methods We conducted a comprehensive search of CNKI, PubMed, The Cochrane Library, Web of Science, EMbase, Wanfang Data, and the Chinese Medical Journal Full-text Database for clinical controlled trials on VATS with different port numbers for spontaneous pneumothorax, from their inception to March 2023. Two researchers independently screened the literature and assessed its quality.The Newcastle-Ottawa Scale (NOS) was used to assess the methodological quality of cohort and case-control studies, and the Cochrane risk-of-bias tool was used to evaluate randomized controlled trials (RCT). Meta-analysis was performed using RevMan 5.4.1 software. Results A total of 107 studies were included, comprising 35 RCT, 2 cohort studies, and 70 case-control studies. All cohort and case-control studies included in the analysis had NOS scores≥7. The meta-analysis revealed that compared to two-port VATS (2P-VATS) and three-port VATS (3P-VATS), single-port thoracoscopic surgery (SPTS) was associated with less intraoperative blood loss (SMD=–1.58, 95%CI: –1.93 to –1.22, P<0.001; and SMD=–1.59, 95%CI: –2.03 to –1.14, P<0.001, respectively), shorter postoperative hospital stay (SMD=–1.05, 95%CI: –1.29 to –0.82, P<0.001; and SMD=–1.08, 95%CI: –1.39 to –0.77, P<0.001), shorter duration of postoperative chest tube drainage (SMD=–0.75, 95%CI: –1.00 to –0.50, P<0.001; and SMD=–1.23, 95%CI: –1.72 to –0.75, P<0.001), fewer postoperative complications (OR=0.34, 95%CI: 0.26 to 0.45, P<0.001; and OR=0.47, 95%CI: 0.33 to 0.68, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P<0.05). The operative time for SPTS was shorter than that for 2P-VATS (SMD=–0.53, 95%CI: –0.90 to –0.16, P=0.005) but showed no significant difference compared to 3P-VATS (P=0.21). When comparing 2P-VATS with 3P-VATS, 2P-VATS demonstrated less intraoperative blood loss (SMD=–1.02, 95%CI: –1.81 to –0.22, P=0.01), shorter postoperative hospital stay (SMD=–0.59, 95%CI: –1.11 to –0.06, P=0.03), shorter duration of chest tube drainage (SMD=–0.46, 95%CI: –0.85 to –0.08, P=0.02), fewer postoperative complications (OR=0.36, 95%CI: 0.22 to 0.59, P<0.001), and lower pain scores at 24, 48, and 72 hours after surgery (P≤0.05). Conclusion Both SPTS and 2P-VATS are effective and safe surgical options for spontaneous pneumothorax, deserving further promotion and application in clinical practice. However, due to limitations in the quantity and quality of the included studies, more large-sample, high-quality research is needed to validate these findings.

Objective To systematically evaluate the efficacy of immune checkpoint inhibitors (ICIs) in treating esophageal cancer patients of different genders. Methods Computer searches were conducted on PubMed, Cochrane Library, and Embase databases to collect randomized controlled trial (RCT) on ICIs treatment for esophageal cancer patients from the establishment of the databases to January 25, 2024. Two researchers independently screened the literature and extracted data according to the inclusion and exclusion criteria. The outcome indicators were overall survival (OS) and progression-free survival (PFS), and RevMan 5.4 software was used for meta-analysis. The modified Jadad scoring scale was used to evaluate the quality of the included literature. Results A total of 10 RCT involving 5364 esophageal cancer patients were included in this study, with 2684 patients in the trial group and 2680 patients in the control group. The Jadad scores of the included literature were all ≥6 points, indicating high-quality RCT. Meta-analysis results showed that female esophageal cancer patients receiving ICIs treatment [HR=0.72, 95%CI (0.59, 0.87), P<0.001] had a more significant median OS prolongation than male patients [HR=0.73, 95%CI (0.68, 0.78), P<0.001]; while male patients [HR=0.57, 95%CI (0.52, 0.64), P<0.001] had a more significant PFS prolongation than female patients [HR=0.72, 95%CI (0.55, 0.94), P=0.01]. Female patients treated with ICIs alone [HR=0.66, 95%CI (0.50, 0.87), P=0.003] had a more significant median OS prolongation than male patients [HR=0.79, 95%CI (0.72, 0.87), P<0.001]; while male patients receiving ICIs combined with chemotherapy [HR=0.67, 95%CI (0.61, 0.74), P<0.001] had a more significant median OS prolongation than female patients [HR=0.77, 95%CI (0.59, 1.01), P=0.06]. Conclusion Female patients receiving ICIs have a slight advantage in OS compared to male patients, while male patients have an advantage in PFS. Male patients receiving ICIs combined with chemotherapy have better survival benefits than female patients, while female patients using ICIs monotherapy have better survival benefits than male patients.

Objective To analyze survival outcomes and influencing factors among patients with colorectal cancer in Yunnan Province. Methods Clinical data were retrospectively collected from 4 892 patients with colorectal cancer. Survival data were obtained through follow-up. Overall survival (OS) was calculated by using the Kaplan-Meier method. Univariate analysis was performed by applying the log-rank test. Meanwhile, multivariate analysis employed the Cox proportional hazards regression model. Results The 1-, 3-, 5-, and 10-year OS rates for the entire cohort were 91.90%, 74.40%, 64.40%, and 28.70%, respectively. Univariate analysis revealed that age, ethnicity, region, differentiation grade, TNM stage, clinical stage, metastatic status, histological type, and treatment modality (chemotherapy, radiotherapy, and surgery) were associated with patient prognosis (all P<0.05). Multivariate analysis identified age (HR=1.250), region (HR=1.262), differentiation grade (HR=0.761), clinical stage (HR=3.128), and treatment modality (chemotherapy, HR=0.644; radiotherapy, HR=1.605; surgery, HR=0.384) as independent factors affecting survival prognosis in patients with colorectal cancer (all P<0.001). Conclusion Age, region, clinical stage, and treatment modality are independent factors influencing survival among patients with colorectal cancer in Yunnan Province. In clinical practice, these factors should be integrated to develop individualized prevention and treatment strategies, thereby improving patient outcomes.

Objective In order to understand the current resistance status of Aedes albopictus(Ae. albopictus) adult population to commonly used insecticides and the resistance dynamics development in Zhejiang Province and provide a theoretical basis for the scientific and rational use of hygienic insecticides. Methods Resistance determination was carried out using the diagnostic dose method(GB/T 26347-2010)recommended by WHO in the adult mosquito contact cylinder method to monitor the resistance of Ae. albopictus field populations in 11 cities and districts in Zhejiang Province in 2024. Results The monitoring result showed that adult Ae. albopictus in 11 areas were resistant or suspected resistant populations to both cis-cypermethrin and permethrin; suspected and resistant populations to the organophosphate insecticide malathion were as high as 81.82%; while suspected resistance to the carbamate insecticide residual carbofuran accounted for 45.45%, and the rest of the monitoring sites were sensitive to it. Conclusions The result suggest that the generalized resistance of Ae. albopictus populations to pyrethroids and organophosphorus insecticides in the field in Zhejiang Province needs to be highly emphasized. In future mosquito vector and mosquito-borne disease control, insecticides should be selected based on the resistance monitoring information, while following scientific guidelines for insecticide use.

OBJECTIVE To retrospectively analyze the drug resistance characteristics of the patients with multidrug-resistant organisms(MDROs)infections who were hospitalized from 2022 to 2023 and observe the effect of multi-disciplinary teamwork(MDT)mode so as to provide scientific bases for prevention and control of MDROs infec-tions and hospital-associated infections.METHODS A total of 639 patients with MDROs infection who were hospi-talized in Jianyang People's Hospital from Jan.2022 to Dec.2023 were recruited as the research subjects.The clinical data were collected from the patients,the drug resistance characteristics of bacteria were analyzed.The effects of MDT and pharmacological supervision on treatment of the patients with MDROs infection were observed and compared.RESULTS The methicillin-resistant Staphylococcus aureus(MRSA)(359 strains,56.18％)was dominant among the pathogens isolated from the 639 patients with MDROs infections,followed by the carbapen-em-resistant Klebsiella pneumoniae(CRKP)(96 strains,15.02％)and carbapenem-resistant Acinetobacter bau-mannii(82 strains,12.83％).Of the patients with MDROs infection,150(23.47％)were from critical care medicine department,94(14.71％)from pediatrics department,and 82(12.83％)from general surgery de-partment.The result of drug susceptibility test showed that the S.aureus strains were susceptible to linezolid,daptomycin,vancomycin and tigecycline;most of the gram-negative bacteria were susceptible to carbapenems,while the A.baumannii strains were highly resistant to the commonly used antibiotics.The total isolation rate of MDROs and the case-time infection rate of MDROs infections were 14.32％and 0.05％,respectively,after MDT and pharmacological supervision were carried out,lower than those before carried out;the effective treatment rate of the patients with MDROs was 76.47％after MDT and pharmacological supervision were carried out,higher than that before they were carried out,and there were significant differences(all P＜0.05).CONCLUSION MDT and pharmacological supervision may improve the curative effect of the patients with MDROs infection and reduce the isolation rate of MDROs as well as the incidence of hospital-associated infections.

OBJECTIVE To conduct a literature review of one case of follicular lymphoma complicated with iliac bone Cryptococcus neoformans infection so as to raise the understanding of such pathogen in the field of HIV-negative Hodgkin's/non-Hodgkin's lymphoma.METHODS The clinical data were collected from one case of follicular lymphoma patient complicated with C.neoformans infection who was treated in Xinrui Hospital of Xin-wu District,Wuxi City on Feb.24,2023 and retrospectively analyzed.All of relevant literatures regarding to the subject were retrieved in Pubmed,CNKI,Wanfang and VIP databases,and the clinical data of the patients with HIV-negative Hodgkin's/non-Hodgkin's lymphoma with C.neoformans infection were screened out and summa-rized.RESULTS The case was a 28-year-old male and had the underlying disease of follicular lymphoma.The C.neoformans was detected by iliac bone histopathology and metagenome next generation sequencing(mNGS).The condition of the patient improved after the treatment with amphotericin B cholesterol sulphate com-pound and fluconazole.A total of 28 patients,with this case included,were involved in the literature review,23 of whom were male,and 5 were female,and the age ranged between 16 and 79 years old.With respect to major in-fection sites,there were 15(53.57％)cases of cerebral infection,9(32.14％)cases of blood infections,7(25.00％)cases of pulmonary infection,4(14.285％)cases of skin infections,2(7.14％)cases of muscle tis-sue infections,2(7.14％)cases of pleural effusion infections,2(7.14％)cases of bone infections and 1(3.57％)case of bone marrow infection.Totally 11 patients had disseminated Cryptococcus infection,accounting for 39.28％.CONCLUSIONS The C.neoformans infection is seldom detected in the patients with HIV-negative Hodgkin's/non-Hodgkin's lymphoma.The brain is the major infection site with the high probability of dissemina-ted infection.It is necessary for the hospital to deepen the understanding of the pathogen in the field of HIV-negative Hodgkin's/non-Hodgkin's lymphoma.

"When warm evil is received,it first attacks the lungs and then spread to the pericardium reversely"is the general rule of warm diseases.Doctors of different dynasties have different views on the phrase"reverse spread to the pericardium",especially the word"reverse".Professor Tong Xiaolin proposed that the heart governs the mind,the pericardium and the heart are connected in qi,and when the heart is affected by evil,the pericardium instead suffers from the evil.The"reverse spread to the pericardium"proposed by Ye Tianshi is actually the spread of warm evil to the brain.Taking meningococcal meningitis as the basic disease,it can be matched one by one with the typical stages of the transmission of Wei-Qi-Ying-Xue.Combined with the theory of Dingjiao,it is believed that the function of"the heart governing the mind"focuses more on the brain in the modern anatomical sense.Combining traditional Chinese medicine's ideas on diagnosis and treatment of warm diseases with modern medicine,revealing the essence of the disease,grasping the core of the pathogenesis,analyzing the word"reverse"from a new perspective,and exploring its true meaning,is of great significance for clarifying its connotation,exploring the development laws of warm diseases,and guiding the diagnosis and treatment of warm disea-ses.
