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.

Objective To investigate the correlation between hyperuricemia and the risk of type 2 diabetes mellitus, and to explore whether hyperuricemia is an independent risk factor of type 2 diabetes mellitus. Methods Using a prospective cohort study design, 300 adult volunteers who underwent physical examinations at the 3201 Hospital were recruited from January to December 2021. They were divided into a high uric acid group and a non-high uric acid group based on their uric acid levels. The incidence of diabetes in people with different uric acid levels was observed within two years through follow-up. SPSS26.0 software was used to statistically analyze the data. Results The data of this study showed that hyperuricemia significantly increased the risk of type 2 diabetes mellitus (P=0.01，OR=3.551). In addition, BMI had a significant impact on the risk of diabetes (P=0.000，OR =0.115), but the impact of age and gender was not statistically significant (both P>0.05). Conclusion Hyperuricemia is positively correlated to the incidence of type 2 diabetes. The higher the uric acid level, the higher the incidence of type 2 diabetes. The uric acid level has a good evaluation value in the incidence of type 2 diabetes mellitus. This finding provides a basis for early intervention of hyperuricemia as a potential risk factor for type 2 diabetes.

Objective To investigate the clinical characteristics of lower respiratory tract infections oc-currence and respiratory system prognosis in infantile stage of children patients with bronchopulmonary dys-plasia(BPD).Methods Fifty premature infants with lower respiratory tract infection and BPD treated in this hospital from March 2017 to December 2020 were selected as the BPD group and 50 preterm infants with low-er respiratory tract infection without BPD during the same period were selected as the non-BPD group.The clinical data and occurrence situation of respiratory system diseases within 3 years after birth in the two groups were collected and analyzed.Results Compared with the non-BPD group,the incidence rates of tachy-pnoea(48.0%vs.12.0%),wheeze(44.0%vs.10.0%),wheezing rale(44.0%vs.10.0%),three concave sign(28.0%vs.8.0%),cyanosis(20.0%vs.4.0%),severe pneumonia(48.0%vs.12.0%)and respirato-ry failure(20.0%vs.4.0%)in the BPD group were higher,the hospitalization duration[7.5(7.0,10.0)d vs.7.0(6.0,7.0)d]was longer,the reaching peak time ratio[18.20%(14.65%,22.25%)vs.24.85%(19.55%,32.78%)],the reaching peak volume ratio[22.15%(19.43%,23.83%)vs.25.65%(22.40%,34.90%)]and the inspiratory/expiratory ratio(0.70±0.12 vs.0.76±0.11)were lower,the 3-year total lower respiratory tract infection times[5.0(4.0,10.0)times vs.3.0(2.0,5.0)times],wheeze times[2.0(1.0,4.0)times vs.0.5(0,1.0)times],the hospitalization times[3.00(2.00,5.00)times vs.2.00(1.00,2.00)times],severe pneumonia times[2.0(1.0,2.0)times vs.1.0(0,1.0)times]and wheeze times in differ-ent ages were more,total hospitalization duration[29.50(19.50,38.25)d vs.13.00(7.00,17.75)d]was lon-ger,the differences were statistically significant(P<0.05).Conclusion The children patients with BPD are prone to lower respiratory tract infections,especially 0-<1 years old,the proportion of severe pneumonia af-ter infection is higher and wheezing is easily to develop.

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).

Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. Scutellaria barbata D. Don (SB) and Scleromitrion diffusum (Willd.) R. J. Wang (SD), a classic TCM herbal pair exhibited anti-inflammatory and antioxidant activities. Using advanced chromatographic separation technology, we enriched the effective fractions of water extracts from SB-SD, obtaining self-assembled herbal nanoparticles (SB and SD nanoparticles, SSNPs) rich in flavonoids and terpenoids. These SSNPs demonstrated robust antioxidant properties in vitro and mitigated AKI progression in vivo by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Oral administration of SSNPs in mice resulted in absorption into the bloodstream, formation of a protein corona, reduced macrophage phagocytosis, and enhanced bioavailability and renal targeting. Furthermore, we investigated the self-assembly principle of SSNPs using representative flavonoids and terpenoids. Kinetic studies and in situ transmission electron microscopy (in situ TEM) revealed that these compounds self-assemble via supramolecular forces like hydrogen bonding and π-π interactions, forming stable nanostructures. This study elucidates the renoprotective effects and mechanisms of SB and SD, and provides a novel approach for the development of TCM-based nanomedicines, highlighting the potential of nano-TCM in AKI treatment.

OBJECTIVE: Cassiae Semen (CS, Juemingzi in Chinese) is a widely used traditional Chinese medicine with a variety of pharmacological effects. This study aimed to investigate the potential therapeutic effects and molecular mechanisms of anthraquinones of CS (AQS) for adiposity. METHODS: The chemical components of the AQS were determined using high-performance liquid chromatography (HPLC). Network pharmacology analysis was used to predict potential anti-obesity targets of action for AQS. We constructed high fat with high sugar water diet-induced obese mice and observed their body weight and whole-body lipid metabolism to evaluate the efficacy of AQS in promoting lipid metabolism. Subsequently, the epidermal temperature at the brown adipose tissue (BAT) before and after cold stimulation was observed and the expression of lipid metabolism-related genes in the liver and BAT tissues was detected to clarify the mechanism of action of AQS. RESULTS: Network pharmacology analysis showed that AQS was involved in the regulation of liver and adipose tissue function under obesity. Pathological and biochemical results showed that AQS reduced lipid accumulation in the liver and adipose tissue induced by an unhealthy diet. With the increase of cold tolerance, the volume and weight of BAT were increased by AQS, suggesting that it regulated the body heat production dominated by BAT. After AQS treatment, the levels of genes related to uncoupling protein1 (UCP1)-mediated adaptive thermogenesis in BAT tissues and lipid metabolism in the liver were also increased, which further proved that AQS activated BAT function to promote lipid metabolism in the whole body. CONCLUSION This study revealed the pharmacological effects of AQS, thereby providing a scientific basis for regulating BAT thermogenesis and liver lipid metabolism to alleviate obesity and providing clues for further exploring the application of natural active ingredients in the treatment of metabolism-related diseases.

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.

BACKGROUND:Cellular pyroptosis is an important pathological mechanism of cerebral ischemia/reperfusion injury.Buyang Huanwu Tang is a classic formula for the clinical treatment of ischemic stroke in traditional Chinese medicine,and cellular pyroptosis may be an effective target of Buyang Huanwu Tang in the treatment of cerebral ischemia/reperfusion injury.OBJECTIVE:To observe the effect and mechanism of Buyang Huanwu Tang on pyroptosis in brain tissues of middle cerebral artery occlusion/reperfusion rats.METHODS:Forty-eight Sprague-Dawley rats were randomly divided into sham operation group,model group,Astragalus membranaceus group and Buyang Huanwu Tang group.Except for the sham operation group,all groups were subjected to middle cerebral artery occlusion for ischemia for 2 hours and reperfusion for 72 hours.The rats in the Astragalus membranaceus group and Buyang Huanwu Tang group were continuously gavaged with the corresponding volume of drugs until ischemia and reperfusion for 72 hours after awakening from the modeling,once in the morning and once in the evening.Zea Longa score was used to observe the neurological deficits of rats.TTC staining was performed to observe cerebral infarct size in rats.Hematoxylin-eosin staining was used to observe the pathological changes of the brain tissue.Immunofluorescence was used to observe the co-expression of Tunel and Cleaved-Caspase-1 in the brain tissue and the expression of the junction protein ASC.Immunohistochemistry and western blot were used to detect the expression of pyroptosis-related proteins in rat brain tissues.RESULTS AND CONCLUSION:(1)Compared with the sham operation group,the neurological deficit score of rats was significantly higher in the model group(P<0.01),and compared with the model group,the neurological deficit score of rats was significantly lower in the Buyang Huanwu Tang group and the Astragalus membranaceus group(P<0.01).(2)Compared with the model group,the volume ratio of cerebral infarction was lower in the Astragalus membranaceus group and Buyang Huanwu Tang group(P<0.01).(3)In the model group,the nuclei of neuronal cells in the brain tissue were deeply stained or lysed,and arrangement of the cells was disorganized.Compared with the model group,the pathologic damage of the brain was less severe in the Buyang Huanwu Tang group and the Astragalus membranaceus group.(4)Compared with the sham operation group,the number of Tunel and Cleaved-Caspase-1 double-positive cells and immunofluorescence intensity of ASC in the brain tissue was significantly increased in the model group,and the expression of Cleaved-Caspase-1,NLRP3,interleukin 18,and interleukin 1β was significantly elevated in the model group(P<0.01).Compared with the model group,the number of Cleaved-Caspase-1 and Tunel double-positive cells,immunofluorescence intensity of ASC,and the expression of Cleaved-Caspase-1,NLRP3,interleukin 18,and interleukin 1β were all significantly decreased in the Buyang Huanwu Tang group and the Astragalus membranaceus group(P<0.01).The results indicate that Buyang Huanwu Tang and its monarch drug Astragalus membranaceus can effectively alleviate brain tissue injury in rats with middle cerebral artery occlusion and reperfusion,and its mechanism may be related to the inhibition of neuronal cell pyroptosis.

Objective To explore the immediate impact of acute vision changes in hemiplegic patients on their gait.Methods Thirty visually normal hemiplegic patients were recruited.Plane mirrors(0°),concave lenses(+150°,+450°)were selected to simulate normal vision,moderate myopia,and high myopia scenarios for straight line walking tests.The Qualisys three-dimensional(3D)motion capture system and Kistler 3D force platform were employed to collect kinematic and dynamic parameters of the patients,and the differences in related indicators before and after visual intervention were compared.Results Visual intervention affected the step length,walking speed,and joint angles of hemiplegic patients.Especially after acute vision changes,there was a significant difference in the stride length and ankle joint angles on the patient's affected side.Under high myopia,the step length and step length symmetry were better than those under moderate myopia,but at the expense of gait speed.Visual intervention led to asymmetric trends in step the length symmetry and joint angle symmetry.There were very significant differences in center of pressure(COP)and COP symmetry between normal vision and high myopia.Conclusions Acute vision changes can affect the gait of hemiplegic patients,especially in individuals with high myopia presenting both a notable decrease in walking speed and an increased ankle range of motion,and an increase in walking speed with moderate myopia.Meanwhile,the symmetry of the COP decreases,indicating that acute vision changes lead to a higher risk of falls for patients.Reasonable vision assessment and corresponding intervention measures are expected to improve walking ability and life quality of the patients.

Objective To compare the safety of laparoscopic pancreatoduodenectomy(LPD)and open pancreatoduodenectomy(OPD)and analyze the learning curve and safety at different stages of LPD.Methods A retrospective analysis was conducted on the clinical data of 50 LPD patients and 54 OPD patients in the Department of Hepatopancreatobiliary Surgery of Suzhou Hospital Affiliated to Nanjing Medical University from January 2020 to June 2024,and intraoperative and postoperative conditions were compared.The Cumulative Sum(CUSUM)analysis method was used to analyze the technical nodes of the LPD learning curve.Results There were no significant differences in operation time and intraoperative blood loss between the LPD group and the OPD group(P＞0.05).There was also no significant difference in the incidence rates of pancreatic fistula(grade B and C),delayed gastric emptying,postoperative bleeding,biliary fistula and intra-abdominal infection between the LPD group and the OPD group(P＞0.05).A time series plot of operation time was drawn based on the patient's operation time and surgical sequence,yielding a fitted curve.Curve analysis showed initial stage and stable stage were finished at the 17th and 24th cases.The LPD learning curve could be divided into three stages:stage Ⅰ characterized as the initial stage(cases 1 to 17),stage Ⅱ characterized as the stable stage(cases 18 to 24),and stage Ⅲ characterized as the proficient stage(cases 25 to 50).The operation time in stages Ⅱ and Ⅲ was significantly shorter than that in stage Ⅰ,and the intraoperative blood loss in stage Ⅰ was significantly higher than that in stage Ⅲ(P＜0.05).There was no significant difference in the incidence of complications among the three stages(P＞0.05).Conclusion LPD and OPD show no significant differences in indications and safety.The LPD learning curve can be divided into three stages.As the number of surgeries completed increa-ses,the operation time of physicians gradually shortens,and the incidence of complications of patients gradually decreases.
