ObjectiveTo develop a scale for evaluating the syndrome of internal retention of dampness and turbidity in nonalcoholic fatty liver disease （NAFLD） that combines disease and syndrome and has the characteristics of traditional Chinese medicine （TCM）. MethodsAn item pool was established for evaluating the syndrome of internal retention of dampness and turbidity in nonalcoholic fatty liver disease （NAFLD） with reference to the guideline for developing international scales. A clinical survey was conducted among the outpatients and inpatients who were diagnosed with NAFLD and had the syndrome of internal retention of dampness and turbidity in Department of Hepatology and Spleen-Stomach， The First Affiliated Hospital of Henan University of Chinese Medicine， from June to August， 2023， and the items were screened based on the classical test theory and the item response theory. An expert questionnaire was developed， and expert discussions were conducted using the Delphi method to identify the items for evaluating the syndrome of internal retention of dampness and turbidity in NAFLD. Finally， the scale was given scientific scores. ResultsA preliminary item pool was established， with 16 primary items and 22 secondary items， and it was divided into the two dimensions of disease and syndrome type. Clinical pre-survey suggested to retain 9 primary items and 14 secondary items， while the Delphi expert questionnaire recommended to retain 11 primary items and 15 secondary items， and tongue manifestation and pulse manifestation were no longer used for assessing the severity of syndrome. After hierarchical analysis and scientific assignment of scores， the scale for evaluating the syndrome of internal retention of dampness and turbidity in NAFLD had a total score of 123 points and 9 important items， i.e.， discomfort in the hypochondrium， abdominal fullness and distension， obesity， heaviness of the head and body， loose stool， anorexia， coughing up phlegm， nausea with a tendency to vomit， and lethargy. ConclusionA preliminary scale is established for evaluating the syndrome of internal retention of dampness and turbidity in NAFLD， which fills the gap in this research field and provides a basis for further clinical application.

OBJECTIVE To compare the clinical efficacy and safety of remimazolam and propofol in general anesthesia induction and maintenance for elderly patients undergoing thoracoscopic lobectomy. METHODS A total of 86 elderly lung cancer patients who underwent thoracoscopic lobectomy at Chongqing University Three Gorges Hospital from February to July 2024 were selected and divided into the propofol group and the remimazolam group according to the randomized numerical table method， with 43 cases in each group. During anesthesia induction， patients in the propofol group and the remimazolam group were intravenously administered 2 mg/kg of Propofol medium- and long-chain fat emulsion injection or 0.25 mg/kg of Remimazolam tosilate for injection， respectively； during anesthesia maintenance， the two groups received intravenous infusion of 6-10 mg/（kg·h） of Propofol medium- and long- chain fat emulsion injection or 1-3 mg/（kg·h） of Remimazolam tosilate for injection， respectively. The anesthesia effects， anesthesia-related indicators， intraoperative opioid and muscle relaxant dosages， Ramsay sedation score， numerical rating scale （NRS） score， and hemodynamic parameters were compared between the two groups， and the occurrence of adverse drug reactions was recorded. RESULTS A total of 41 patients in the propofol group and 43 patients in the remimazolam group completed the trial. The proportion of patients with grade Ⅰ anesthesia effect in the remimazolam group was significantly higher than that in the propofol group， while the proportion of patients with grade Ⅱ anesthesia effect was significantly lower than that in the propofol group （P＜0.05）. In this group， the disappearance time of eyelash reflex， the time taken for the bispectral index to drop to 60， and the Ramsay sedation scores （2 and 6 hours after operation） were all significantly prolonged or increased， while the recovery time， NRS scores （2 and 6 hours after operation）， and the incidence of intraoperative hypotension were all significantly shortened or reduced； moreover， the improvements of the above sedation/NRS scores exhibited a time-dependent pattern within 2 to 24 hours after operation （P＜0.05）. Compared with before anesthesia induction （T0）， the heart rate [except at 2 min after medication （T1）， 60 min after anesthesia （T4）， and at the end of surgery （T5） in the remimazolam group] and mean arterial pressure [except at T1 in the remimazolam group] of patients in both groups significantly decreased at T1， 5 min after medication （T2）， at the start of surgery （T3）， T4， and T5 （P＜0.05）. Meanwhile， regional cerebral oxygen saturation significantly increased in both groups. Furthermore， the heart rate and mean arterial pressure of patients in the remimazolam group were significantly higher than those in the propofol group at T1， T2 and T4 （P＜0.05）. No statistically significant differences were observed between the two groups in terms of postanesthesia care unit stay time， dosage of opioids and muscle relaxants， regional cerebral oxygen saturation， or peripheral oxygen saturation at various time points （P＞0.05）. CONCLUSIONS Compared to propofol， remimazolam demonstrates superior anesthesia effects when used for the induction and maintenance of general anesthesia in elderly patients undergoing thoracoscopic lobectomy. It not only provides more stable intraoperative hemodynamics and shortens the postoperative recovery time but also effectively reduces the incidence of intraoperative hypotension.

Checkpoint blockade immunotherapy has emerged as a transformative approach in cancer treatment by activating tumor-infiltrating T cells. However, the efficacy of PD-L1 blockade is restricted in "cold" tumors, which are characterized by low immunogenicity, presenting a challenge to immunotherapy. This study introduces an innovative strategy, utilizing cathepsin-cleavable N-(2-hydroxypropyl) methacrylamide (HPMA) polymer-assisted combined photodynamic therapy (PDT) and PD-L1 degradation for the first time, effectively treating T cell-deficient tumors. The degradable main-chain polymer, conjugated with photosensitizer porphyrin, facilitates the accumulation of reactive oxygen species (ROS), triggering immunogenic cell death (ICD) and promoting cytotoxic T lymphocytes (CTLs) infiltration into tumors. Multivalent peptide antagonists of PD-L1 promote PD-L1 degradation in lysosomes through receptor crosslinking, overcoming the adaptive cycling of PD-L1 to the tumor cell surface. These findings demonstrate that polymer-assisted PDT and PD-L1 crosslinking degradation represent a potential novel strategy for anti-tumor immunotherapy, providing valuable tools for expanding immunotherapy applications in immunosuppressive cancers.

Objective To investigate correlations of dynamic changes in serum C-reactive pro-tein(CRP),procalcitonin(PCT),and neutrophil-to-lymphocyte ratio(NLR)before and after symptomatic treatment with prognosis of neonates with neonatal respiratory distress syndrome(NRDS)of different etiologies.Methods A total of 110 premature infants were selected as study subjects and divided into neonatal infection group(group A)and fetal intrauterine distress group(group B)based on different causes of NRDS.Additionally,30 neonates with NRDS caused solely by prematurity were selected as control group.Serum CRP and PCT levels and NLR were compared among the three groups before and after treatment.Results There were statistically significant differences in oxygen therapy duration,ventilation duration,the proportion of infants requiring re-intubation,hospital stay,and the number of apnea episodes among three groups(P＜0.006).Before treatment,there was no sta-tistically significant difference in serum CRP levels between group A and group B(P＞0.05).Ser-um CRP levels in group B were higher than those in the control group.Moreover,serum PCT levels was lower than the group A,and NLR in the group B were higher than those in the group A and the control group.CRP,PCT levels,and NLR in the group A were higher than those in the control group(P＜0.05 or P＜0.006).After treatment,serum CRP levels in all three groups decreased compared to before treatment.Serum PCT levels in the group A decreased compared to before treat-ment.NLR in both group A and group B decreased compared to before treatment,with statistically significant differences(P＜0.006).There were statistically significant differences in serum CRP and PCT levels between the group A and the control group after treatment(P＜0.006).After treat-ment,there was a statistically significant difference in serum CRP levels between the group B and the control group(P＜0.006),but no statistically significant differences in PCT levels and NLR(P＞0.05).Compared with group A,there was a statistically significant difference in PCT levels in the group B(P＜0.006).Multivariate Logistic regression results showed that CRP,PCT,and NLR were independent influencing factors for the prognosis of infants in the group A.The receiver operat-ing characteristic curve analysis results showed that the areas under the curve(AUC)after treatment for serum CRP,PCT,and NLR alone in predicting prognosis in the group A were 0.789,0.738,and 0.758,respectively,and the AUC for combined prediction was 0.934.In the group B,the AUC for serum CRP,PCT,and NLR alone in predicting prognosis after treatment were 0.719,0.772,and 0.768,respectively,and the AUC for combined prediction was 0.886.The sensitivity and specificity of combined prediction in both groups were higher than those of each indicator alone,and the predictive value of their combined detection for the prognosis of premature infants in group A was higher than that in the group B.Conclusion There are differences in PCT levels and NLR before treatment among neonates with NRDS of different etiologies.After symptomatic treatment,CRP,PCT levels and NLR decrease in all three groups,indicating a good prognosis.

Objective To investigate the effects of galangin on the migration and invasion abilities of cervical cancer Hela cells and its potential mechanisms.Methods Hela cells were treated with different concentrations of galangin(0,5,10,20,40,60,80,100 μmol/L)for 48 hours,and CCK-8 assay was used to assess the impact of galangin on cell viability and to determine the half-maximal lethal concentration(IC50)of galangin.Hela cells were divided into a control group(0 μmol/L)and a galangin group(40 μmol/L treatment).Scratch wound healing assays and Transwell chamber assays were conducted to evaluate the migration and invasion abilities of the cells in each group.Western Blot was used to detect the protein expression of E-cadherin and N-cadherin.DIA quantitative proteomics technology was used to detect and screen the differentially expressed proteins between the two groups.Biological function enrichment analysis of the differential genes was performed using the KEGG Pathway and Gene Set Enrichment Analysis(GSEA)methods.Western Blot was used to verify the expression levels of Hippo/YAP signaling pathway-related proteins YAP and p-YAP.Results Compared to the control group,galangin(40 μmol/L)significantly inhibited the viability of Hela cells in a concentration-dependent manner(P<0.001).Compared with the control group,the scratch healing ability and invasion ability of cervical cancer Hela cells treated with galangin(40 μmol/L)were significantly reduced(P<0.001).The expression of E-cadherin protein was increased(P<0.05)and the expression of N-cadherin protein was decreased(P<0.001)in the galangin group(40 μmol/L)compared to the control group.KEGG and GSEA enrichment results indicated that the inhibition of malignant progression in cervical cancer by galangin was significantly associated with the Hippo/YAP signaling pathway.Western Blot confirmed that the expression level of the hallmark protein p-YAP in the Hippo signaling pathway was increased(P<0.01),while the expression level of YAP protein was decreased(P<0.05).Conclusion Galangin inhibits the proliferation,migration and invasion abilities of Hela cells in a dose-dependent manner.The underlying mechanism might be associated with the activation of the Hippo/YAP signaling pathway.

Objective To investigate the effect of transmembrane protein CD147 expression on AIM2 inflammasome-mediated pyroptosis and proliferation of cervical cancer cells.Methods Western Blot was used to detect the expression of CD147 in cervical cancer cell lines SiHa(HPV+)and C33a(HPV-)and normal cervical epithelial cells H8(HPV+)and HCer Epic(HPV-).SiHa cells were transfected with lentivirus to down-regulate the expression of CD147.According to the different treatments,SiHa cells were divided into SiHa group,negative control group(shCD147-NON),knockdown group 1(shCD147-1)and knockdown group 2(shCD147-2).The transfection effect was verified by Western Blot,RT-qPCR and green fluorescence expression.The protein and mRNA expressions of AIM2,Caspase-1,IL-18 and GSDMD were detected by Western Blot and RT-qPCR.The lactate dehydrogenase(LDH)release was measured in the cell culture supernatant,and the cell morphology was observed under the fluorescence inverted microscope;the proliferation ability of cells was measured by CCK-8 and the colony formation ability was measured by cell cloning experiments.Results Western Blot results showed that CD147 protein expression in SiHa cells was the highest compared with that in HCerEpic cells.CD147 low expression lentivirus effectively down-regulated the expression of CD147 in SiHa cells.The results of Western Blot and RT-qPCR experiments showed that the expression of AIM 2,Caspase-1,IL-18,GSDMD protein and mRNA increased in shCD147-1 and shCD147-2 group(P<0.05).Lactate dehydrogenase(LDH)release assay showed that compared with the SiHa group,the shCD147 group had a significant increase in LDH release(P<0.05).Fluorescence inverted microscope showed that the shCD147 group had swelling and vacuolization,showing typical pyroptosis.Compared with the SiHa group,the shCD147-1 and shCD147-2 groups had significantly reduced the cell proliferation and colony formation ability(P<0.05).Conclusion Low expression of CD147 effectively up-regulates the expression of AIM2 inflammation-related factors in cervical cancer SiHa cells,induces the pyroptosis,and inhibits the cell proliferation and cloning.

Purpose To investigate the effect of CD147 on the proliferation,invasion and migration of cervical cancer cells and its potential molecular mechanism.Methods The expres-sion data of BSG gene(encoding CD147 protein)in cervical cancer samples were downloaded from UCSC database,and the prognosis of different groups of samples was evaluated by Log-rank test.Western blot was used to detect CD147 expression in the Siha and Hela and H8 cells.The expression of CD147 was downregulated by the lentivirus transfection into Hela cells and its transfection efficiency was verified.Western blot was used to detect the expression of p-Akt,p-mTOR,ACC1,FASN,E-cad-herin and N-cadherin in each group.The content of fatty acids in the cells was detected by BODIPY staining and fatty acid kit.Cell proliferation,invasion and migration were detected by CCK-8,plate cloning and Transwell assay.The cell proliferation,in-vasion and migration ability were detected by plate cloning ex-periment and Transwell test.Results The expression of CD147 in cervical cancer tissues was higher than that in normal cervical tissues(P＜0.01).Patients with overexpression of CD147 had poor prognosis.Western blot results showed that compared with H8 cells,the expression of CD147 protein in Siha and Hela cells was increased(P=0.011).After down-regulation of CD147,the protein expression of CD147,ACC1 and FASN in the sh-CD147 group was decreased compared with those in the Hela group(P＜0.001).BODIPY fluorescence staining was weak-ened and fatty acid content was decreased(P＜0.001).The a-bility of cell colony formation,invasion and migration was de-creased.The expression of E-cadherin protein in sh-CD147 group was increased,and the expression of N-cadherin,p-Akt and p-mTOR was decreased.Compared to sh-CD147,after treatment with Akt agonist SC-79(sh-CD147-SC79),the ex-pression of p-Akt,p-mTOR,ACC1,FASN,N-cadherin in cells was increased,and the expression of E-cadherin was decreased,and the results of lipid staining and fatty acid content were con-sistent with the expression of key enzymes(P＜0.01),and the cell proliferation,invasion and migration ability were significant-ly enhanced.Conclusion CD147 through Akt/mTOR signaling pathways regulating the fatty acid synthesis promotes cervical cancer cell proliferation,invasion and migration.

Objective To analyze the indications and prognosis of the D-J tube internal drainage method in pediatric pyeloplasty surgery.Methods We conducted a retrospective analysis of cases of unilateral pyeloplasty performed in the urology department of the Capital Institute of Pediatrics from January 2012 to January 2022.They were divided into the D-J tube group(396 cases)and the py-elostomy group(334 cases)according to different postoperative drainage methods.The propensity score matching method was used to e-venly match the baseline data of the two groups of cases,and the complications and prognosis of the two drainage methods were compared.Results D-J tube drainage could significantly reduce the average hospitalization time,reduce pain,alleviate skin scars,and improve the quality of medical care and care.D-J tube could increase the risk of postoperative urinary tract infection and re-obstruction in chil-dren,and clinical application should be cautious.A predictive model was established for urinary tract infections after D-J tube implanta-tion,including gender,side profile,height,renal parenchymal thickness,and blood urea nitrogen.Conclusion The D-J tube internal drainage method can significantly reduce the length of hospital stay and nursing burden after pediatric pyeloplasty surgery.Although it may increase the risk of urinary tract infection in the near and medium term,the risk of urinary tract infection can be predicted.The use of D-J tubes should be carefully selected in males,small infants,and severe hydronephrosis.
