OBJECTIVE To systematically evaluate the correlation between dynamic changes in inflammatory markers during treatment with epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKIs） in non-small cell lung cancer （NSCLC） patients and therapeutic efficacy， with the aim of providing evidence-based support for clinical prognosis assessment and treatment strategy adjustment. METHODS Databases including PubMed， Embase， Cochrane Library， CNKI， Wanfang Data， and CBM were searched from the inception to July 20， 2025. Following literature screening， data extraction and quality assessment， descriptive analysis was conducted on the outcomes of included studies. RESULTS A total of eight studies were included to analyze the correlation of 6 inflammatory markers before and after treatment with EGFR-TKIs with therapeutic efficacy. The risk of bias assessment identified six high-quality studies and two moderate-quality studies. Among these studies， seven studies demonstrated that lower levels of neutrophil-to-lymphocyte ratio （NLR）， derived neutrophil-to-lymphocyte ratio （dNLR）， platelet-to-lymphocyte ratio （PLR）， and monocyte-to-lymphocyte ratio （MLR）， higher lymphocyte-to-monocyte ratio （LMR） before treatment， as well as decreased NLR and MLR and increased LMR after treatment were associated with longer median progression-free survival. Five studies indicated that lower levels of NLR， dNLR， PLR， and interleukin-6 （IL-6）， higher LMR before treatment as well as decreased NLR and dNLR and increased LMR were associated with longer median overall survival. Three studies indicated that lower levels of IL-6 were associated with a higher objective response rate， while the association of these markers after treatment remained controversial； another study showed that an early decline in NLR， MLR， and PLR after treatment may be associated with objective response benefit. CONCLUSIONS Lower inflammatory levels during EGFR-TKIs therapy correlate with better therapeutic efficacy in NSCLC patients.

The NLRP3 inflammasome's core and most specific protein, NLRP3, has a variety of functions in inflammation-driven diseases. Costunolide (COS) is the major active ingredient of the traditional Chinese medicinal herb Saussurea lappa and has anti-inflammatory activity, but the principal mechanism and molecular target of COS remain unclear. Here, we show that COS covalently binds to cysteine 598 in NACHT domain of NLRP3, altering the ATPase activity and assembly of NLRP3 inflammasome. We declare COS's great anti-inflammasome efficacy in macrophages and disease models of gouty arthritis and ulcerative colitis via inhibiting NLRP3 inflammasome activation. We also reveal that the α-methylene-γ-butyrolactone motif in sesquiterpene lactone is the certain active group in inhibiting NLRP3 activation. Taken together, NLRP3 is identified as a direct target of COS for its anti-inflammasome activity. COS, especially the α-methylene-γ-butyrolactone motif in COS structure, might be used to design and produce novel NLRP3 inhibitors as a lead compound.

Objective: To analyze the characteristics of individuals positive for SARS-CoV-2 nucleic acid in a centralized isolation site for people entering China in Huzhou City of Zhejiang Province from December 18, 2021 to January 12, 2022, so as to provide insights into the prevention and control of overseas imported COVID-19. Methods: The basic characteristics, nucleic acid detection and epidemiological investigations were collected from individuals positive for SARS-CoV-2 nucleic acid in a centralized isolation site for people entering China from December 18, 2021 to January 12, 2022, and the temporal distribution, population distribution, source of importation, and virus typing were descriptively analyzed. Results : From December 18, 2021 to January 12, 2022, a total of 2 974 individuals in 19 flights were recorded in this centralized isolation site, and 33 cases were tested positive for SARS-CoV-2 nucleic acid, including 21 confirmed cases with common type, 9 confirmed cases with mild type, and 3 cases with asymptomatic infections. There were 11 cases with Omicron infections ( 33.33% ), 5 cases with Delta infections ( 15.15% ), and 17 cases with infection of unidentified types ( 51.52% ). The median interval ( interquartile range ) from the time of entry to the time of a positive test was 4.0 ( 7.0 ) days among all positive cases, 0 ( 4.0 ) day among cases with Omicron infections and 4.5 ( 8.5 ) days among cases with infections of Delta and unidentified types. The positive cases had a mean age of ( 36.97±8.58 ) years, and included 27 men (81.82%). There were 30 cases ( 90.91% ) receiving two and more doses of COVID-19 vaccines, and 7 cases ( 21.21% ) with a previous history of SARS-CoV-2 infections. There were 19 cases ( 57.58% ) from African countries, and 7 of 11 cases with Omicron infections were imported from African countries. Conclusion Omicron infection was predominant among individuals positive for SARS-CoV-2 nucleic acid in this centralized isolation site for people entering China from December 18, 2021 to January 12, 2022, with no severe cases detected, and most positive cases were imported from African countries.

PURPOSE: c-Met and its ligand, hepatocyte growth factor (HGF), play a critical role in oncogenesis and metastatic progression. The aim of this study was to identify inhibited enzymogram and to test the antitumor activity of SIM-89 (a c-Met receptor tyrosine kinase inhibitor) in non-small cell lung cancer. MATERIALS AND METHODS: Z′-LYTE kinase assay was employed to screen the kinase enzymogram, and mechanism of action (MOA) analysis was used to identify the inhibited kinases. Cell proliferation was then analyzed by CCK8 assay, and cell migration was determined by transwell assay. The gene expression and the phosphorylation of c-Met were examined by realtime-PCR and western blotting, respectively. Finally, the secretion of HGF was detected by ELISA assay. RESULTS: c-Met, activated protein kinase (AMPK), and tyrosine kinase A (TRKA) were inhibited by SIM-89 with the IC₅₀ values of 297 nmol/L, 1.31 µmol/L, and 150.2 nmol/L, respectively. SIM-89 exerted adenosine triphosphate (ATP) competitive inhibition on c-Met. Moreover, the expressions of STAT1, JAK1, and c-Met in H460 cells were decreased by SIM-89 treatment, and c-Met phosphorylation was suppressed in A549, H441, H1299, and B16F10 cells by the treatment. In addition, SIM-89 treatment significantly decreased the level of HGF, which accounted for the activation of c-Met receptor tyrosine kinase. Finally, we showed cell proliferation inhibition and cell migration suppression in H460 and H1299 cells after SIM-89 treatment. CONCLUSION: In conclusion, SIM-89 inhibits tumor cell proliferation, migration and HGF autocrine, suggesting it's potential antitumor activity.

BACKGROUND:Major complication after total hip replacement was instability in the form of dislocation. The probability of above complications has a great relationship with the mistakes of the angle of acetabular cup prosthesis. OBJECTIVE:To explore the influence of angle of acetabular cup in total hip replacement on the safety of joint flexion and extension. METHODS: A total of 60 patients, who underwent total hip replacement in the Wujin Hospital Affiliated to Jiangsu University from January 2012 to December 2014, were enroled in this study. Three dimensional directional monitoring device, CT scanning and image processing tools were used to preset the angle of the acetabular cup and to set abduction angle and anteversion angle. Test data were recorded and subjected to statistical analysis. RESULTS AND CONCLUSION:Acetabular cup was implanted under five different conditions: abduction angle 45°, anteversion angle 15°; abduction angle 60°, anteversion angle 15°; abduction angle 30°, anteversion angle 15°; abduction angle 45°, anteversion angle 5°; abduction angle 45°, anteversion angle 25°. According to statistics, in the patients with anteversion angle of 15°, when the acetabular cup was placed, the bigger the abduction angle, the bigger the range of abduction angle of the acetabular cup induced by pelvic tilt was. If the anteversion angle increased, the anteversion angle of the acetabular cup was reduced. With the increased pelvic tilt angle, the anteversion angle of the acetabular cup was big. Moreover, in patients with anteversion angle of 15°, the anteversion angle of the acetabular cup should keep consistent. When the abduction angle of the acetabular cup increased, the range of anteversion angle of the acetabular cup induced by pelvic tilt was diminished. These data showed that the abduction angle and anteversion angle of the acetabular cup have mutual restriction. When the acetabular cup was placed, big anteversion angle (15±10)° can wrap the femoral head, reduce the incidence of dislocation, and make flexion and extension safe.

Objective To investigate the therapeutic effects of botulinum toxin type A (BTX-A) in elderly patients with primary intractable trigeminal neuralgia.Methods 27 elderly patients with primary intractable trigeminal neuralgia were treated with BTX-A local multiple point injection.The efficacy was assessed by visual analog scores (VAS) before and 1 week,2 weeks,1 month,3 months and 6 months after the treatment.Results VAS scores was (9.2±1.1),(5.8±3.0),(3.6± 2.3),(2.3±2.3),(3.2±2.9) and (4.6±3.2) before and 1 week,2 weeks,1 month,3 months and 6 months after BTX-A treatment respectively.VAS score was gradually decreased,reached the lowest at 1 month after BTX-A injection,and then was gradually increased.There were significant differences in VAS scores between between pre-and post-treatment (P＜0.05).The efficiency was 37.0％,85.2％,92.6％,70.4％ and 59.3％ at 1 week,2 weeks,1 month,3 months and 6 months after the treatment respectively.There were significant differences in efficacy between different time points after the treatment (all P＜0.05).3 patients had the transient numbness of mouth askew and incomplete eyelid closure and recovered spontaneously after 4-8 weeks.No severe adverse effects were found in the other 27 patients.Conclusions BTX-A is safe and effective in the treatment of primary intractable trigeminal neuralgia in elderly patients.

Objective To explore the correlation of patient-controlled sedation of dexmedetomidine and Narcotrend values. Methods Forty patients with lower limb surgery were enrolled. Until CSEA block fixed , the electronic pump ran the patient-controlled sedation of dexmedetomidine. The parameter of electronic pump was set as follows: load dose 2 mL + background dose 1.5 mL/h + single dose 0.5 mL + locktime 20 s. The heart rate , mean arterial pressure, pressing times, effective times, OAA/S sedation scores and NI values were determined. Results At T4 point, the patients reached appropriate sedation. At T4 ~ T9 OAA/S scores kept 3 to 4. From T5 point, NI values showed significant decrease. After the T7 point. OAA/S scores and NI values reached the plateau time of (7.5 ± 1.8) min and (13.1 ± 3.4) min, OAA/S scores of 1, 2, 3, 4, respectively, corresponding roughly with NI values 95 to 100, 90 to 94, 65 to 89, 40 to 64. The correlation coefficient was 0.58. The time of NI values significant decreased in the younger group and in the elderly group, with (10.2 ± 1.6) min and (14.4 ± 2.2) min. In T5~ T9 point, NI values of the younger group were significantly lower than those in the elderly group. Conclusion Relevant relationships are observed between dexmedetomidine patient-controlled sedation depth and the narcotrend values under CSEA.

Objective To optimize the concentration of polyethylene glycol (PEG) for the growth of Chlamydia trachomatis (Ct) reference strains D-UW-5/Cx and E-UW-5/Cx,and to evaluate the effects of PEG on the sensitivity of Ct to 4 common antibiotics.Methods After the inoculation of Ct standard strains (D-UW-5/Cx and E-UW-5/Cx) into McCoy cell monolayer,different concentrations of PEG were added into the culture medium followed by centrifugation.After 2 hours of incubation at 37 ℃,the inoculum was removed and a complete culture medium containing 1 μg/mL cycloheximide was added followed by another 48-hour culture.Subsequently,the culture was fixed and subjected to iodine staining for the calculation of Ct inclusions and optimization of PEG for the growth of Ct.Some Ct standard strains were used to infect McCoy cells,with PEG (0.7％,wt/vol) added to the culture medium after inoculation and before centrifugation process,and when the infection rate reached higher than 90％,a microdilution method was utilized to evaluate the minimal inhibitory concentration (MIC) of 4 antibiotics,including azithromycin,minocyline,moxifloxacin and doxycycline.Thirty-one clinical specimens,which had been confirmed to be positive for Ct serovar D or E strain,were inoculated into McCoy cell monolayer for the passage of Ct with or without the presence of 0.7％ PEG.Results The optimal concentration of PEG was 0.7％ for the growth of Ct,and this concentration of PEG could increase the number of inclusion bodies of Ct serovar E by 3.44 folds,and that of Ct serovar D by 3.56 folds.In vitro,the MICs of the 4 antibiotics were consistent between PEG-treated and untreated Ct reference strains.Moreover,PEG notably increased the quantity of inclusion bodies of Ct serovar E or D from clinical specimens after passages.Conclusions PEG (0.7％) can enhance the growth of Ct serovar D and E,but has no obvious influence on antimicrobial susceptibility of Ct.
