Purpose: Cancer has become a significant major public health concern, making the discovery of new cancer markers or therapeutic targets exceptionally important. Elevated expression of tumor necrosis factor receptor superfamily member 12A (TNFRSF12A) expression has been observed in certain types of cancer. This project aims to investigate the function of TNFRSF12A in tumors and the underlying mechanisms. Materials and Methods: Various websites were utilized for conducting the bioinformatics analysis. Tumor cell lines with stable knockdown or overexpression of TNFRSF12A were established for cell phenotyping experiments and subcutaneous tumorigenesis in BALB/c mice. RNA-seq was employed to investigate the mechanism of TNFRSF12A. Results: TNFRSF12A was upregulated in the majority of cancers and associated with a poor prognosis. Knockdown TNFRSF12A hindered the colorectal cancer progression, while overexpression facilitated malignancy both in vitro and in vivo. TNFRSF12A overexpression led to increased nuclear factor кB (NF-κB) signaling and significant upregulation of baculoviral IAP repeat containing 3 (BIRC3), a transcription target of the NF-κB member RELA, and it was experimentally confirmed to be a critical downstream factor of TNFRSF12A. Therefore, we speculated the existence of a TNFRSF12A/RELA/BIRC3 regulatory axis in colorectal cancer. Conclusion TNFRSF12A is upregulated in various cancer types and associated with a poor prognosis. In colorectal cancer, elevated TNFRSF12A expression promotes tumor growth, potentially through the TNFRSF12A/RELA/BIRC3 regulatory axis.

AIM: To explore the diagnostic value of combining the corneal stress-strain index(SSI)with corneal biomechanical parameters for early keratoconus.METHODS:A retrospective study was conducted on 34 patients(53 eyes)with early keratoconus diagnosed and treated in our hospital from March 2022 to February 2024. Additionally, 112 normal volunteers(112 eyes)who underwent physical examinations in our hospital during the same period were selected as a healthy control group. The CorvisST equipment was utilized for measurement and recorded deformation with Scheimpflug camera to obtain 10 biomechanical parameters: first applanation time(A1T), first applanation length(A1L), velocity of initial applanation(Vin), second applanation time(A2T), second applanation length(A2L), velocity of outward applanation(Vout), highest concavity time(HCT), highest concavity depth of applanation(HCDA), highest concavity radius(HCR), and peak distance(PD), as well as stress-strain index(SSI), and the corneal biomechanical parameters of the two groups were compared. Furthermore, Logistic regression analysis was used to identify the risk factors for keratoconus, and ROC curves were plotted to analyze the biomechanical parameters of the cornea for early diagnosis of keratoconus.RESULTS:The SSI(0.77±0.17)in patients with keratoconus was lower than that in healthy controls(1.01±0.24; P<0.001). Patients with keratoconus had lower A1T, A1L, A2L, and HCR, and higher Vout, HCDA, and PD compared to healthy controls(all P<0.001). Logistic regression analysis showed that decreased SSI, A1T, A1L, A2L, and HCR, as well as increased Vout, HCDA, and PD, were risk factors for the development of keratoconus(P<0.001). ROC curve analysis showed that the AUC value for combined diagnosis of early keratoconus was 0.997, with a Youden's index of 0.954, sensitivity and specificity of 98.1% and 97.3%, respectively, and a 95% CI of 0.994-1.000.CONCLUSION:The combination of SSI and corneal biomechanical parameters holds diagnostic significance for early keratoconus, and the joint diagnostic value is even higher. It can be considered as a diagnostic or screening indicator for early keratoconus.

Allergic asthma is a complex，polygenic disease characterized by chronic inflammation and airway hyperresponsiveness. Fungus and dust mites are the most important inhaled allergens of allergic asthma，and often exist in the form of mixed allergens. In recent years，genetic studies have shown that several genes are associated with allergic asthma attacks. This article reviews the studies on the genes related to allergic asthma caused by dust mites and fungus，such as a disintegrin and metalloproteinase 33（ADAM33），interleukin-4（IL-4），glycoprotein A repetitions predominant（GARP），toll like receptor 3（TLR3），mannose-binding lectin 2（MBL2），chemokine（C-C motif）ligand 17（CCL17）and other genes .

AIM: To analyze the influencing factors of postoperative dry eye complication after corneal transplantation and to build a nomogram prediction model.METHODS: Clinical data were collected on 117 patients who underwent corneal transplantation at our hospital from March 2021 to February 2023. They were divided into dry eye group(n=96)and non-dry eye group(n=21)according to whether there was a postoperative dry eye. The risk factors of postoperative complication of dry eye after corneal transplantation were analyzed, the nomogram prediction model for predicting postoperative complication of dry eye after corneal transplantation was constructed, and the internal validation of the model and the prediction efficacy were assessed by calibration curves and decision curves, respectively.RESULTS: Comorbid diabetes mellitus, comorbid sleep disorders, comorbid meibomian gland dysfunction, chronic eye drop abuse, chronic corneal contact lens wear, interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α)were the risk factors for the complication of dry eye after corneal transplantation(P<0.05). The nomogram model predicted a C-index of 0.890(95% CI 0.877-0.903). The nomogram model had a threshold >0.07, and the nomogram model provided higher net clinical benefit than the single index in all cases.CONCLUSION: The nomogram model built in this study based on the factors affecting the complication of dry eye after corneal transplantation has a good predictive value for the complication of dry eye after corneal transplantation.

Background::Total human immunodeficiency virus (HIV) DNA and integrated HIV DNA are widely used markers of HIV persistence. Droplet digital polymerase chain reaction (ddPCR) can be used for absolute quantification without needing a standard curve. Here, we developed duplex ddPCR assays to detect and quantify total HIV DNA and integrated HIV DNA.Methods::The limit of detection, dynamic ranges, sensitivity, and reproducibility were evaluated by plasmid constructs containing both the HIV long terminal repeat (LTR) and human CD3 gene (for total HIV DNA) and ACH-2 cells (for integrated HIV DNA). Forty-two cases on stable suppressive antiretroviral therapy (ART) were assayed in total HIV DNA and integrated HIV DNA. Correlation coefficient analysis was performed on the data related to DNA copies and cluster of differentiation 4 positive (CD4 +) T-cell counts, CD8 + T-cell counts and CD4/CD8 T-cell ratio, respectively. The assay linear dynamic range and lower limit of detection (LLOD) were also assessed. Results::The assay could detect the presence of HIV-1 copies 100% at concentrations of 6.3 copies/reaction, and the estimated LLOD of the ddPCR assay was 4.4 HIV DNA copies/reaction (95% confidence intervals [CI]: 3.6-6.5 copies/reaction) with linearity over a 5-log 10-unit range in total HIV DNA assay. For the integrated HIV DNA assay, the LLOD was 8.0 copies/reaction (95% CI: 5.8-16.6 copies/reaction) with linearity over a 3-log 10-unit range. Total HIV DNA in CD4 + T cells was positively associated with integrated HIV DNA ( r = 0.76, P <0.0001). Meanwhile, both total HIV DNA and integrated HIV DNA in CD4 + T cells were inversely correlated with the ratio of CD4/CD8 but positively correlated with the CD8 + T-cell counts. Conclusions::This ddPCR assay can quantify total HIV DNA and integrated HIV DNA efficiently with robustness and sensitivity. It can be readily adapted for measuring HIV DNA with non-B clades, and it could be beneficial for testing in clinical trials.

Objective To compare the effect of posterior cruciate ligament retaining(CR)and posterior cruciate substituting(PS)prosthesis in knee arthroplasty.Methods 64 patients with knee osteoarthritis were admitted to our department from June 2021 to June 2022 and whom met the selection criteria were randomly selected and divided into observation group and control group(n = 32).CR prosthesis was used in the observation group,and PS prosthesis was used in the control group.Operation time,postoperative drainage volume,difference of hemoglobin(HGB)before and after operation,postoperative hospital stay,postoperative range of motion at 7 d,14 d,45 d,3 months and 1 year were recorded.ROM,visual analog pain Scale(VAS),Hospital for special surgery(HSS)score,and maximum forward and backward displacement of knee joint and the regular radiographs were also recorded,too.Results The two groups were similar in terms of operation time,postoperative hospital stay,postoperative VAS score and maximum anterior and posterior displacement of knee joint,with P values greater than 0.05,which had no statistical significance.The postoperative drainage volume in the observation group was significantly less than that in the control group,with statistical significance(P＜0.05).The HGB difference of observation group was significantly lower than that of control group,with statistical significance(P＜0.05).There was no statistically significant differ-ence in ROM and HSS scores between the two groups before surgery;the ROM and HSS scores of the control group at 7,14 and 45 days after surgery was better than that of the observation group,with statistical significance(P＜0.05);the ROM and HSS scores of the two groups at 3 months after surgery was not statistically significant.The ROM and HSS scores in the observation group was better than that in the control group at 6 months and 1 year after operation,and the difference was statistically significant(P＜0.05).Conclusions CR prosthesis is superior to PS prosthesis in terms of intraoperative blood loss and post-operative drainage volume,which can reduce surgical risk.Both kinds of prosthesis can achieve good knee stability after surgery,while PS prosthesis has better early clinical effect,while CR prosthesis has better long-term clinical effect.

Objective To investigate the value of the volume percentage of solid component in differential diagnosis of stage Ⅰ lung adenocarcinoma subtypes,and to predict the optimal critical CT value of solid component.Methods A total of 962 nodules with sur-gical pathological findings confirmed as adenocarcinoma in situ(AIS)or pulmonary adenocarcinoma and manifested as subsolid nod-ules on thin-section CT were analyzed retrospectively,and divided the lesions into:(1)AIS(n=350)or pulmonary adenocarcinoma(n=612)groups;and(2)minimally invasive adenocarcinoma(MIA)(n=213)or invasive adenocarcinoma(IAC)(n=399)groups based on pathological findings.The volume percentage of solid components within pulmonary nodules was measured via CT density histogram analysis at different thresholds,the diagnostic efficacy of different thresholds was analyzed and the optimal critical CT val-ues of solid component was found.Results In the AIS versus pulmonary adenocarcinoma groups,age,mass,and volume percentage of solid component were statistically significant(P＜0.001);the CT threshold of-350 HU had the highest diagnostic efficacy[area under the curve(AUC)0.859,accuracy 81.69％,sensitivity 85.60％,and specificity 74.86％,respetively],and the critical value of volume percentage of solid component determined under this threshold was 8.3％.In the MIA versus IAC groups,age(P=0.017),mass(P＜0.001),and volume percentage of solid component(P＜0.001)were statistically significant;the CT threshold of-350 HU had the highest diagnostic efficacy(AUC 0.857,accuracy 78.27％,sensitivity 82.91％,and specificity 69.48％,respectively),and the critical value of volume percentage of solid component determined under this threshold was 16.9％.Conclusion The volume percentage of solid component measured based on CT density histogram analysis may be helpful in the differential diagnosis of early stage lung ade-nocarcinoma subtypes.
