Risk prediction models for postoperative pulmonary complications (PPCs) can assist healthcare professionals in assessing the likelihood of PPCs occurring after surgery, thereby supporting rapid decision-making. This study evaluated the merits, limitations, and challenges of these models, focusing on model types, construction methods, performance, and clinical applications. The findings indicate that current risk prediction models for PPCs following lung cancer surgery demonstrate a certain level of predictive effectiveness. However, there are notable deficiencies in study design, clinical implementation, and reporting transparency. Future research should prioritize large-scale, prospective, multi-center studies that utilize multiomics approaches to ensure robust data for accurate predictions, ultimately facilitating clinical translation, adoption, and promotion.

Solute carriers (SLCs) constitute the largest superfamily of membrane transporter proteins. These transporters, present in various SLC families, play a vital role in energy metabolism by facilitating the transport of diverse substances, including glucose, fatty acids, amino acids, nucleotides, and ions. They actively participate in the regulation of glucose metabolism at various steps, such as glucose uptake (e.g., SLC2A4/GLUT4), glucose reabsorption (e.g., SLC5A2/SGLT2), thermogenesis (e.g., SLC25A7/UCP-1), and ATP production (e.g., SLC25A4/ANT1 and SLC25A5/ANT2). The activities of these transporters contribute to the pathogenesis of type 2 diabetes mellitus (T2DM). Notably, SLC5A2 has emerged as a valid drug target for T2DM due to its role in renal glucose reabsorption, leading to groundbreaking advancements in diabetes drug discovery. Alongside SLC5A2, multiple families of SLC transporters involved in the regulation of glucose homeostasis hold potential applications for T2DM therapy. SLCs also impact drug metabolism of diabetic medicines through gene polymorphisms, such as rosiglitazone (SLCO1B1/OATP1B1) and metformin (SLC22A1-3/OCT1-3 and SLC47A1, 2/MATE1, 2). By consolidating insights into the biological activities and clinical relevance of SLC transporters in T2DM, this review offers a comprehensive update on their roles in controlling glucose metabolism as potential drug targets.

Objective:To investigate the clinical efficacy of Cyclosporine A(CsA)in patients with unexplained repeated implantation failure(URIF),and to analyze the changes of peripheral blood lymphocyte subsets after CsA treatment.Methods:105 patients with URIF who underwent frozen-thawed embryo transfer(FET)in the De-partment of Reproductive Medicine in The Second Affiliated Hospital of Kunming Medical University from Septem-ber 30,2021 to March 1,2022 were selected.After informed consent,the patients were divided into CsA group(n=52)and control group(n=53)according to whether they received CsA treatment or not.Pregnancy outcomes and changes in lymphocyte subset were compared between the two groups.Results:The embryo implantation rate and clinical pregnancy rate in CsA group were higher than those in the control group,the difference was statisti-cally significant(48.91%vs.32.56%,P=0.027;53.85%vs.32.08%,P=0.024).The CsA group had a lower ear-ly abortion rate than the control group(10.71%vs.23.53%),but the difference was not statistically significant(P=0.25).The percentage of CD3-CD16+CD56+in CsA group was significantly decreased after treatment[(16.15±5.37)%vs.(18.23±7.10)%,P=0.012],it was also lower than that in the control group[(16.15±5.37)%vs.(18.67±5.16)%,P=0.018].Conclusions:CsA treatment can significantly improve the clinical preg-nancy rate and embryo implantation rate of frozen-thawed embryo transfer in patients with URIF,which may be a-chieved by promoting the distribution of peripheral blood lymphocytes to the direction of embryo implantation,es-pecially by down-regulating the percentage of CD3-CD16+CD56+.CsA has a certain application prospect in the field of assisted reproduction.

Objective To investigate the effect and mechanism of Yiguan Decoction(YGJD)on the efficacy of M1 bone marrow-derived macrophages(M1-BMDMs)in the treatment of rats with liver cirrhosis induced by 2-AAF/CCl4.Methods BMDMs were isolated and induced into M1-BMDMs by lipopolysaccharide.A total of 50 male Wistar rats were randomly divided into normal group with 5 rats and model group with 45 rats.The rats for modeling were given subcutaneous injection of 50%CCl4 twice a week.Since week 7,the rats for modeling were randomly divided into model group(M group),YGJD group,M1-BMDM group,M1-BMDM+YGJD group,and sorafenib(SORA)group,and they were given subcutaneous injection of 30%CCl4 to maintain the progression of liver cirrhosis and intragastric administration of 2-AAF.CCR2 inhibitors were added to the drinking water,and each group was given the corresponding intervention.Related samples were collected at week 9.The rats were observed in terms of serum liver function parameters,liver pathology,hydroxyproline(Hyp)content in liver tissue,hepatic stellate cell activation,hepatic fibrosis and inflammation factors,and the expression levels of molecules associated with the Wnt signaling pathway.A one-way analysis of variance was used for comparison of continuous data between multiple groups,and the least significant difference t-test was used for further comparison between two groups.Results Compared with the M group,the M1-BMDM+YGJD group had significant reductions in the serum levels of alanine aminotransferase,aspartate aminotransferase,and total bilirubin(TBil)(all P<0.05)and a significant increase in the content of albumin(Alb)(P<0.05),and compared with the M1-BMDM group,the M1-BMDM+YGJD group had a significant reduction in the serum level of TBil(P<0.05)and a significant increase in the serum level of Alb(P<0.05).Compared with the M1-BMDM group,the M1-BMDM+YGJD group had significant reductions in the expression levels of CD68 and TNF-α(P<0.05).Compared with the M1-BMDM group,the M1-BMDM+YGJD group had significant reductions in Hyp content and Sirius red positive area(P<0.05).As for the non-canonical Wnt signaling pathway molecules,compared with the M1-BMDM group,the M1-BMDM+YGJD group had significantly lower mRNA and protein expression levels of Wnt5a(P<0.05)and mRNA expression level of Fzd2(P<0.05),as well as significant reductions in the mRNA expression levels of Wnt4,Wnt5b,and Fzd3(P<0.05),while there were no significant changes in the mRNA expression levels of the canonical Wnt signaling pathway molecules β-catenin,LRP5,LRP6,Fzd5,and TCF.Conclusion YGJD can enhance the therapeutic effect of M1-BMDMs on rats with liver cirrhosis induced by 2-AAF/CCl4,possibly by inhibiting the non-canonical Wnt5a/Fzd2 signaling pathway,which provides new ideas for the synergistic effect of traditional Chinese medicine on M1-BMDMs in the treatment of liver cirrhosis.

MethodsRat BMDMs were isolated and polarized into M2 phenotype， and rat BMSCs were isolated and co-cultured with M2-BMDMs at the third generation to obtain BMSC^M2. The rats were given subcutaneous injection of CCl₄ for 6 weeks to establish a model of liver cirrhosis， and then they were randomly divided into model group （M group）， BMSC group， and BMSC^M2 group， with 6 rats in each group. A normal group （N group） with 6 rats was also established. Since week 7， the model rats were given 2-AAF by gavage in addition to the subcutaneous injection of CCl₄. Samples were collected at the end of week 10 to observe liver function， liver histopathology， and hydroxyproline （Hyp） content in liver tissue， as well as changes in the markers for hepatic stellate cells， hepatic progenitor cells， cholangiocytes， and hepatocytes. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the N group， the M group had significant increases in the activities of serum alanine aminotransferase （ALT） and aspartate aminotransferase （AST） （P<0.01）； compared with the M group， the BMSC and BMSC^M2 groups had significant reductions in ALT and AST （P<0.01）， and the BMSC^M2 group had significantly better activities than the BMSC group （P<0.05）. Compared with the N group， the M group had significant increases in Hyp content and the mRNA and protein expression levels of alpha-smooth muscle actin （α-SMA） in the liver （P<0.01）； compared with the M group， the BMSC and BMSC^M2 groups had significant reductions in Hyp content and the expression of α-SMA （P<0.05）， and the BMSC^M2 group had a significantly lower level of α-SMA than the BMSC group （P<0.01）. Compared with the N group， the M group had significant increases in the mRNA expression levels of the hepatic progenitor cell markers EpCam and Sox9 and the cholangiocyte markers CK7 and CK19 （P<0.01） and significant reductions in the expression levels of the hepatocyte markers HNF-4α and Alb （P<0.01）； compared with the M group， the BMSC and BMSC^M2 groups had significant reductions in the mRNA expression levels of EpCam， Sox9， CK7， and CK19 （P<0.05） and significant increases in the mRNA expression levels of HNF-4α and Alb （P<0.05）， and compared with the BMSC group， the BMSC^M2 group had significant reductions in the mRNA expression levels of EpCam and CK19 （P<0.05） and significant increase in the expression level of HNF-4α （P<0.05）. ConclusionM2-BMDMs can enhance the therapeutic effect of BMSCs on CCl₄/2-AAF-induced liver cirrhosis in rats， which provides new ideas for further improving the therapeutic effect of BMSCs on liver cirrhosis.

Objective To discuss the clinical application value of super selective renal artery embolization-assisted(SRAE-assisted)laparoscopic partial nephrectomy(LPN).Methods A retrospective analysis of the clinical data of patients with stage T1 renal carcinoma,who received LPN,was conducted.The patients were divided into SRAE group(performing LPN without adopting renal hilum vascular clamping)and VC group(performing LPN with adopting renal hilum vascular clamping).The time spent for operation,amount of intraoperative blood loss,and preoperative and postoperative renal functions were compared between the two groups.According to the warm ischemia time(WIT),the patients of the VC group were subdivided into WIT＜25 min subgroup and WIT≥25 min subgroup,and the preoperative and postoperative renal functions were compared between the two subgroups.Results A total of 59 patients with renal carcinoma were enrolled in this study,including 12 patients in SRAE group and 47 patients in VC group.In VC group,WIT＜25 min subgroup had 33 patients and WIT≥25 min subgroup had 14 patients.In both SRAE group and VC group,no patient was referred to open surgery or total nephrectomy.No patient in SRAE group was referred to traditional LPN.The time spent for operation in SRAE group and VC group was 100.50(73.75,132.50)min and 120.00(90.00,145.00)min respectively,the difference between the two groups was not statistically significant(P＞0.05).The postoperative estimated glomerular filtration rate(eGFR)in SRAE group was 100.56(82.85,106.81),which was remarkably higher than 84.66(70.84,94.85)in VC group(P＜0.05).The postoperative serum creatinine level in VC group was 90.50(77.10,104.90)μmol/L,which was strikingly higher than 72.24(65.97,80.27)μmol/L in SRAE group(P＜0.05).The amount of intraoperative blood loss in SRAE group was 50(50,50)mL,which was lower than 50(50,100)mL in VC group(P＜0.05).In VC group,the postoperative eGFR in WIT≥25 min subgroup was 66.13(47.08,82.50),which was lower than 90.80(77.18,98.78)in WIT＜25 min subgroup(P＜0.05).During the postoperative one-year follow-up,no recurrence was observed in both groups.Conclusion Compared with traditional LPN,SRAE-assisted LPN doesn't need to obstruct the renal hilus during surgery,which can avoid the ischemic impairment of the residual renal function and reduce the amount of intraoperative blood loss,moreover,it doesn't increase the operation time,doesn't increase the incidence of complications such as postoperative bleeding,etc.and doesn't affect the curative efficacy and patient's prognosis.

Objective:To conduct a scoping review to analyse the types, performance, advantages and disadvantages of cognitive function assessment tools for ICU patients, to provide a reference for the evaluation of cognitive function in ICU patients in future.Methods:A scoping review study was conducted, literature on cognitive function assessment tools for ICU patients in 9 domestic and foreign databases including China National Knowledge Infrastructure, Wanfang Database, VIP Database, China Biology Medicine disc, PubMed, Web of Science, Cochrane Library, Embase and CINAHL were systematically searched. The search period was from the establishment of the database to May 20, 2024. Literature was independently screened by 2 researchers and relevant information was extracted and summarized.Results:Totally 17 studies were included, with 9 tools for assessing cognitive function in ICU patients, including 6 questionnaires, 1 test battery, 1 assessment software, and 1 telephone interview questionnaire. All of above were generalizable tools, except for the Chinese and English versions of the John-Hopkins Adapted Cognitive Exam as ICU-specific tools. The Mini-Mental State Examination was the most widely used assessment scale.Conclusions:Appropriate assessment tools should be selected according to the specific clinical setting, but there is still a lack of specialized and standardized assessment tools for cognitive dysfunction in ICU patients. In the future, standardized tools which fit our cultural context for evaluating cognitive function in ICU patients should be developed.

Objective:To investigate the interventional effect of bone marrow mesenchymal stem cell (BMMSC) transplantation with different doses of X-ray irradiation induced hepatic injury in mice.Methods:Eighteen female C57BL/6J mice were randomly divided into 0, 2, and 3 Gy irradiation groups and 0, 2, and 3 Gy transplantation groups. The irradiation group was used as the control and injected with an equal volume of culture medium. The mice in the transplantation group were irradiated with different doses of X-ray irradiation, and BMMSCs were intravenously infused into the bone marrow. The mice were sacrificed for sampling at the end of the 21st day. Mice body weight changes were recorded daily. The changes in the content of peripheral blood lymphocytes, red blood cells, platelets, and hemoglobin were detected by an automatic blood tester. The morphological changes in mice liver tissues were observed by hematoxylin-eosin staining. The serum activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected by a biochemical analyzer. The reduced glutathione contents in liver tissue were detected by the microplate method. The malondialdehyde content in liver tissue was detected by thiobarbituric acid. The content of total superoxide dismutase (T-SOD) in liver tissue was detected by the hydroxylamine method. The expression of the F4/80 protein in liver tissue was detected by the immunohistochemistry method. The protein expression of nuclear transcription factor erythroid 2 related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) in liver tissue was determined by the western blotting method. The mRNA expression of NLRP3, IL-6, and Nrf2 in liver tissue was detected by a real-time quantitative polymerase chain reaction. The multiple-group comparisons were analyzed by factorial analysis of variance. The inter-group comparisons were analyzed by the LSD method for statistical analysis.Results:The contents of peripheral blood lymphocytes, erythrocytes, platelets, and hemoglobin were significantly decreased in the 3 Gy irradiation group than the 0 Gy irradiation group ( P<0.05), while the activities of serum ALT and AST were significantly increased ( P<0.05). The malondialdehyde content, F4/80 protein expression level, nucleotide-binding domain and leucine-rich repeats, nucleotide oligomerization domain-like receptor family, pyrin domain containing 3 (NLRP3), and interleukin 6 mRNA expression levels were significantly increased in liver tissue, while the contents of T-SOD and glutathione, Nrf2 and HO-1 protein expression levels, and Nrf2 mRNA expression level in liver tissue were significantly decreased ( P<0.05). The contents of peripheral blood lymphocytes, red blood cells, platelets, and hemoglobin were significantly increased in the 3 Gy transplantation group than the 3 Gy irradiation group ( P<0.05), while the activities of serum ALT and AST were significantly decreased ( P<0.05). The malondialdehyde content, F4/80 protein expression level, NLRP3 and interleukin-6 mRNA expression levels in liver tissue were significantly decreased ( P<0.05), while the content of T-SOD and glutathione, Nrf2 and HO-1 protein expression levels, and Nrf2 mRNA expression level in liver tissue were significantly increased ( P<0.05). Conclusion:X-ray irradiation at a dose of 3 Gy can induce liver oxidative damage in mice. BMMSC transplantation can improve X-ray irradiation-induced liver oxidative damage in mice, and its mechanism of action may be related to the regulation of the Nrf2/HO-1 pathway.

Objective To investigate the acoustic characteristics of monophthong vowels and compound vow-els articulation movement in patients with dysarthria.Methods A total of 24 patients aged 40～81 years old with dysarthria from hospitals,and 24 healthy adults aged 40～80 years old from communities in Shanghai were recrui-ted.The first and second formants(F1,F2)of monophthong vowels/a/,/i/,/u/were extracted from the speech samples,and mandibular distance,tongue distance,vowel space area(VSA)and vowel articulation index(VAI)were calculated.The slope of the second formant of compound vowels/ai/,/ua/,/uai/was extracted and calculat-ed.The acoustic parameters of two groups of subjects were compared under different tasks.Results Under the monophthong vowels task,F1 of/a/,F2 of/i/,mandibular distance,tongue distance,VSA and VAI in the pa-tients were significantly lower than those in the control group(P＜0.01).F2 of/u/was significantly higher than that in the control group(P＜0.01).F2 slope of/ai/,/ua/,/uai/was significantly lower than that of the control group(P＜0.05).Conclusion The space of monophthong vowels articulation movement was reduced in the pa-tients with dysarthria,presenting a state of aggregation.The speed of compound vowels articulation movement was decreased.
