Objective To evaluate the surgical efficacy of unilateral pneumonectomy for the treatment of tuberculous destroyed lung, analyze the causes of severe postoperative complications, and explore clinical management strategies. Methods A retrospective analysis was conducted on the clinical data of patients with tuberculous destroyed lung who underwent unilateral pneumonectomy at the Public Health Clinical Center of Chengdu from 2017 to 2023. Postoperative severe complications were statistically analyzed. Patients were divided into a non-severe complication group and a severe-complication group, and the causes, management, and outcomes of complications were analyzed. Results A total of 134 patients were included, comprising 69 males and 65 females, with a mean age of 17-73 (40.43±12.69) years. There were 93 patients undergoing left pneumonectomy and 41 patients undergoing right pneumonectomy. Preoperative sputum smear was positive in 35 patients, all of which converted to negative postoperatively. There were 58 patients with hemoptysis preoperatively, and none experienced hemoptysis postoperatively. Postoperative incisional infection occurred in 8 (5.97%) patients, and postoperative pulmonary infection in 26 (19.40%) patients. Severe postoperative complications occurred in 17 (12.69%) patients, including empyema in 9 (6.72%) patients, bronchopleural fistula with empyema in 1 (0.75%) patient, severe pneumonia in 3 (2.24%) patients, postpneumonectomy syndrome in 1 (0.75%) patient, chylothorax in 1 (0.75%) patient, ketoacidosis in 1 (0.75%) patient, and heart failure with severe pneumonia in 1 (0.75%) patient. Perioperative mortality occurred in 2 (1.49%) patients, both of whom underwent right pneumonectomy. Multivariate logistic regression analysis revealed that a history of ipsilateral thoracic surgery, concomitant Aspergillus infection, and greater blood loss were independent risk factors for severe complications following unilateral pneumonectomy for tuberculous destroyed lung (P<0.05). Conclusion Unilateral pneumonectomy for patients with tuberculous destroyed lung can significantly improve the clinical cure rate, sputum conversion rate, and hemoptysis cessation rate. However, there is a certain risk of severe perioperative complications and mortality, requiring thorough perioperative management and appropriate management of postoperative complications.

OBJECTIVE To evaluate the efficacy, safety and cost-effectiveness of toripalimab (Tor) combined with chemotherapy (CT) in the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC). METHODS PubMed, the Cochrane Library, Embase, Web of Science, CBM, CNKI, Wanfang Data, and Health Technology Assessment (HTA) related websites were searched to collect the HTA reports, systematic reviews/meta-analyses and pharmacoeconomic studies of Tor+CT in the treatment of locally advanced or metastatic NSCLC from database/website inception to March 31, 2025. After data extraction and quality evaluation, the results of the included studies were analyzed descriptively. RESULTS A total of eleven studies were included, involving five systematic reviews/meta-analyses, and six pharmacoeconomic studies. Among the five systematic reviews/ meta-analyses, two were of high quality, while there was one each of moderate, low, and very low quality. All six pharmacoeconomic studies were of good quality. In terms of efficacy, compared with CT, Tor+CT significantly improved patients’ progression-free survival (PFS) and overall survival (P<0.05). In addition, compared with ipilimumab+CT, durvalumab, durvalumab+tremelimumab and sugemalimab+CT, Tor+CT could also improve the PFS (P<0.05). In terms of safety, there was no significant difference in the incidence of grade≥3 adverse events between patients receiving Tor+CT and CT (P>0.05); while Tor+CT had a lower incidence of grade≥3 adverse E-mail: events, compared with camrelizumab+CT, pembrolizumab+ 3233255290@qq.com ipilimumab, nivolumab+CT and atezolizumab+CT (P<0.05).In terms of cost-effectiveness, Tor+CT treatment had certain cost-effectiveness advantages, compared with CT. CONCLUSIONS Compared with CT, other programmed death-1/programmed death-ligand 1 inhibitors alone, or their combination with CT, Tor+CT for the treatment of locally advanced or metastatic NSCLC has good efficacy, safety and cost-effectiveness.

Soil cadmium pollution can adversely affect the cultivation of the ornamental plant, Coleus scutellarioides. Upon cadmium contamination of the soil, the growth of C. scutellarioides is impeded, and it may even succumb to the toxic accumulation of cadmium. In this study, we investigated the effects of arbuscular mycorrhizal fungi (AMF) on the adaptation of C. scutellarioides to cadmium stress, by measuring the physiological metabolism and the degree of root damage of C. scutellarioides, with Aspergillus oryzae as the test fungi. The results indicated that cadmium stress increased the activity of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), and the content of malondialdehyde (MDA) and proline (Pro) within the cells of C. scutellarioides, but inhibited mycorrhizal infestation rate, root vigour and growth rate to a great degree. With the same cadmium concentration, the inoculation of AMF significantly improved the physiological indexes of C. scutellarioides. The maximum decrease of MDA content was 42.16%, and the content of secondary metabolites rosemarinic acid and anthocyanosides could be increased by up to 27.43% and 25.72%, respectively. Meanwhile, the increase of root vigour was as high as 35.35%, and the DNA damage of the root system was obviously repaired. In conclusion, the inoculation of AMF can promote the accumulation of secondary metabolites, alleviate root damage, and enhance the tolerance to cadmium stress in C. scutellarioides.

The rapid emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants that evade immunity elicited by vaccination has posed a global challenge to the control of the coronavirus disease 2019 (COVID-19) pandemic. Therefore, developing countermeasures that broadly protect against SARS-CoV-2 and related sarbecoviruses is essential. Herein, we have developed a lipid nanoparticle (LNP)-encapsulated mRNA (mRNA-LNP) encoding the full-length Spike (S) glycoprotein of SARS-CoV-2 (termed RG001), which confers complete protection in a non-human primate model. Intramuscular immunization of two doses of RG001 in Rhesus monkey elicited robust neutralizing antibodies and cellular response against SARS-CoV-2 variants, resulting in significantly protected SARS-CoV-2-infected animals from acute lung lesions and complete inhibition of viral replication in all animals immunized with low or high doses of RG001. More importantly, the third dose of RG001 vaccination elicited effective neutralizing antibodies against current epidemic XBB and JN.1 strains and similar cellular response against SARS-CoV-2 Omicron variants (BA.1, XBB.1.16, and JN.1) were observed in immunized mice. All these results together strongly support the great potential of RG001 in preventing the infection of SARS-CoV-2 variants of concern (VOCs).

ObjectiveTo investigate the influencing factors for traditional Chinese medicine (TCM) syndromes in pancreatic cancer by analyzing 608 cases, and to provide a theoretical reference for TCM syndrome differentiation and standardized treatment of pancreatic cancer. MethodsA total of 608 patients with a pathological or clinical diagnosis of pancreatic cancer who were admitted to Shanxi Institute of Traditional Chinese Medicine, The Affiliated Hospital of Shanxi University of Chinese Medicine, and Shanxi Provincial Hospital of Integrated Traditional Chinese and Western Medicine from January 2019 to December 2023 were enrolled, and TCM syndrome differentiation was performed. The chi-square test was used for comparison of categorical data between groups. The clinical data with statistical significance between groups were included in the regression analysis, and the unordered polytomous logistic regression model was used to investigate the influencing factors for the TCM syndrome of pancreatic cancer. ResultsFor the 608 patients with pancreatic cancer, common initial symptoms included abdominal pain (32.40%), abdominal distension (23.85%), fatigue (16.12%), and emaciation (10.03%), and the main clinical symptoms included poor appetite (75.97%), abdominal pain (67.27%), fatigue (61.84%), abdominal distension (57.40%), and emaciation (53.62%). There were significant differences between the patients with different TCM syndromes of pancreatic cancer in sex (χ2=62.823, P<0.001), disease duration (χ2=14.868, P=0.011), clinical stage (χ2=21.006, P<0.001), lymph node metastasis (χ2=2.205, P=0.032), surgery (χ2=38.008, P<0.001), chemotherapy (χ2=21.384, P<0.001), radiotherapy (χ2=17.510, P=0.004), and immunotherapy (χ2=18.573, P=0.002). The logistic regression analysis showed that male sex was a protective factor against Qi and blood deficiency syndrome (odds ratio [OR]=0.081, 95% confidence interval [CI]: 0.031 — 0.213, P<0.001), Qi stagnation and blood stasis syndrome (OR=0.100, 95%CI: 0.041 — 0.247, P<0.001), and syndrome of Yin deficiency with internal heat (OR=0.158, 95%CI: 0.057 — 0.444, P<0.001), while it was a risk factor for the syndrome of damp-heat accumulation (OR=2.378, 95%CI: 1.074 — 5.266, P=0.033); the course of the disease of<1 year was a protective factor against Qi and blood deficiency syndrome (OR=0.167, 95%CI: 0.073 — 0.383, P<0.001), syndrome of spleen-kidney Yang deficiency (OR=0.183, 95%CI: 0.089 — 0.378, P<0.001), and syndrome of Yin deficiency and internal heat (OR=0.164, 95%CI: 0.070 — 0.385, P<0.001); clinical stage Ⅰ/Ⅱ/Ⅲ was a risk factor for damp-heat accumulation (OR=2.793, 95%CI: 1.259 — 6.196, P=0.012) and Qi stagnation and blood stasis syndrome (OR=7.863, 95%CI: 2.808 — 22.020, P<0.001); lymph node metastasis was a risk factor for Qi and blood deficiency syndrome (OR=4.005, 95%CI: 1.477 — 10.861, P=0.006); surgical treatment was a risk factor for Qi and blood deficiency syndrome (OR=4.151, 95%CI: 1.916 — 8.995, P<0.001), syndrome of spleen-kidney yang deficiency (OR=5.352, 95%CI: 2.436 — 11.759, P<0.001), Qi stagnation and blood stasis syndrome (OR=2.334, 95%CI: 1.071 — 5.088, P=0.033), and syndrome of Yin deficiency and internal heat (OR=4.167, 95%CI: 1.789 — 9.707, P<0.001); chemotherapy was a protective factor against damp-heat accumulation (OR=0.188, 95%CI: 0.082 — 0.428, P<0.001); radiotherapy was a risk factor for damp-heat accumulation (OR=2.571, 95%CI: 1.151 — 5.746, P=0.021) and syndrome of Yin deficiency with internal heat (OR=8.384, 95%CI: 3.348 — 20.997, P<0.001); immunotherapy was a risk factor for Qi and blood deficiency syndrome (OR=2.114, 95%CI: 1.021 — 4.379, P=0.044). ConclusionSex, course of the disease, clinical stage, presence or absence of lymph node metastasis, surgery, chemotherapy, radiotherapy, and immunotherapy are the main influencing factors for the TCM syndrome of pancreatic cancer.

Objective To explore the role of mitophagy in pancreatic cancer cachexia-induced muscle atrophy and its underlying mechanism.Methods Six male C57BL/6J mice(8 weeks old,weighing 20~30 g)were equally and randomly divided into a control group(intrapancreatic injection of normal saline)and a cachexia group(orthotopic pancreatic injection of KPC1199 cells).After successful model establishment,gastrocnemius muscles were harvested for transmission electron microscopy(TEM)to assess mitochondrial ultrastructure.Western blotting was performed to quantify mitochondrial respiratory chain complexes(Ⅰ~Ⅳ)and autophagy-related proteins,while immunofluorescence staining was conducted to evaluate mitochondrial-lysosomal colocalization.In in vitro experiments,C2C12 myoblasts were differentiated into myotubes,and then divided into a control group(standard culture)and a cachexia group(co-cultured with KPC1199 cells for 48 h using transwell chambers).Mitochondrial-lysosomal colocalization and autophagy-related protein expression were analyzed with immunofluorescence assay and Western blotting.The mitochondrial division inhibitor Mdivi-1(20 μmol/L)was added to the co-culture system to assess its myotube diameter.Results Compared to the control mice,the cachectic mice exhibited mitochondrial swelling,reduced cristae density,and significantly increased mitochondrial-lysosomal colocalization in gastrocnemius muscle(P<0.05).Western blotting revealed the expression levels of mitochondrial respiratory chain proteins complexⅠ(1.00±0.04 vs 0.51±0.04,P<0.05),complexⅡ(1.00±0.13 vs 0.73±0.15,P<0.05),complexⅢ(1.00±0.20 vs 0.64±0.01,P<0.05),complexⅣ(1.00±0.06 vs 0.65±0.02,P<0.05)and PGC1α(1.00±0.03 vs 0.62±0.06,P<0.05)were decreased,and the levels of mitophagy markers,LC3-Ⅰ/Ⅱ(1.00±0.14 vs 1.65±0.25,P<0.05),PINK1(1.00±0.11 vs 1.51±0.05,P<0.05),and BNIP3(1.00±0.22 vs 2.02±0.10,P<0.05)were elevated when compared to the control.In the C2C12 myotube model,tumor cell co-culture increased mitochondrial-lysosomal colocalization and upregulated mitophagy-related protein expression(P<0.05),consistent with the in vivo findings.Mdivi-1 treatment increased myotube diameter from 220.6±35.5 μm to 315.0±39.1 μm(R2=0.666 5,P<0.05).Conclusion Mitophagy is activated in pancreatic cancer cachexia-induced muscle atrophy.Inhibiting mitophagy can effectively alleviate muscle atrophy induced by pancreatic cancer cachexia.

Objective:To compare the effect of transcranial magnetic stimulation (rTMS) of the contralesional hemisphere at different frequencies on the recovery of upper limb motor function after a moderate-to-severe ischemic stroke.Methods:The inter-hemisphere compensation model was applied along with electroencephalogram (EEG) power spectrum density measurements. Thirty stroke survivors were randomly assigned to a sham stimulation group ( n=9), a high-frequency stimulation group ( n=11) or a low-frequency stimulation group ( n=10). In addition to physical and pharmacological therapy, the low-frequency and high-frequency groups received 1Hz or 5Hz rTMS, while the sham group received sham stimulation. The rTMS was delivered over the contralesional (unaffected) hemisphere once daily for 20 minutes over 15 consecutive days. Before, as well as 7 and 15 days after the treatment, all of the subjects′ motor functioning was assessed using the Fugl-Meyer Assessment for the upper extremity (FMA-UE) and their ability in the activities of daily living was assessed using the modified Barthel Index (MBI). Resting-state EEGs with the eyes closed were also recorded, and absolute alpha power across the whole brain was calculated. Changes from baseline FMA-UE and MBI scores and absolute alpha power were analyzed using one-way and repeated-measures analysis of variance. Results:After the treatment, significant within-group improvements from baseline were observed in the FMA-UE scores, MBIs and absolute alpha power, except for absolute alpha power in the low-frequency and sham groups. The repeated-measures analysis of variance revealed significant time × group interactions for FMA-UE ( F=9.926, P≤0.001), MBI ( F=8.789, P≤0.001) and absolute alpha power ( F=4.511, P≤0.05). So the treatment effects varied among the groups. Post hoc Bonferroni-corrected comparisons showed that the high-frequency group exhibited significantly greater improvements from baseline in terms of all three indicators compared with the other two groups. Conclusions:High-frequency (5Hz) rTMS applied to the contralesional hemisphere produced greater improvement than low-frequency (1Hz) stimulation in the upper limb motor function of patients with moderate-to-severe stroke. These findings support the use of the interhemispheric compensation model to guide rTMS therapy, particularly for patients with FMA-UE scores below 43.
