Objective:To investigate the diagnostic value of plasma cytokines such as interleukin (IL)-2, IL-6 and interferon (IFN)-γ in non-Hodgkin lymphoma (NHL).Methods:A retrospective case-control study was conducted. A total of 48 NHL patients admitted to the Second Affiliated Hospital of Xuzhou Medical University between January 2020 and December 2022 were selected as NHL group, and another 34 healthy people who underwent physical examimation during the same period were selected as the healthy control group. The levels of IL-2, IL-4, IL-6, IL-10, IL-17, tumor necrosis factor (TNF) - α and IFN-γ in the plasma of patients at first admission and healthy subjects during physical examination were detected by using flow cytometry. The differences in general data and all cytokines levels of both groups were compared. The collinearity stepwise screening was made in 7 cytokines levels, and the screened variables were included in multivariate binary logistic regression model. Plasma cytokines with independent effects on the pathogenesis of NHL were screened. Taking local biopsy, histopathological examination or immunohistochemical examination as the gold standard, the receiver operating characteristic (ROC) curves of individual and combined diagnosis of NHL based on the selected cytokines were drawn to judge the diagnostic effect of all indicators on NHL.Results:There were 32 males (66.7%) and 16 females (33.3%) in NHL group, with the median age [ M ( Q1, Q3)] of 56.50 (45.75, 67.50) years; there were 28 males (82.4%) and 6 females (17.6%) in the healthy control group, with the median age of 52.00 (47.50, 55.50) years. There were no statistically significant differences in age and gender composition between the 2 groups (all P > 0.05). The levels of IL-2 [1.44 (1.36, 1.85) pg/ml vs. 1.19 (0.86, 1.68) pg/ml] and TNF-α [3.46 (2.68, 4.06) pg/ml vs. 2.23 (1.52, 3.46) pg/ml] in NHL group were higher than those in the healthy control group, and the differences were statistically significant (all P < 0.05). There were no statistically significant differences in IL-4, IL-6, IL-10, IL-17, IFN-γ levels (all P > 0.05). According to collinear stepwise screening of independent variables, IL-4 and TNF-α were excluded from 7 cytokines, and the other 5 cytokines were included in multivariate logistic regression model, and the result showed that the decreased level of IL-2 ( OR = 0.20, 95% CI: 0.08-0.53, P = 0.001) and the increased levels of IL-6 ( OR = 1.18, 95% CI: 1.04-1.33, P = 0.009) and IFN-γ ( OR = 1.26, 95% CI: 1.08-1.46, P = 0.003) were independent risk factors for the onset of NHL. The results showed that the area under the curve of IL-2, IL-6, IFN-γ and the combination of 3 indexes for the diagnosis of NHL was 0.760 (95% CI: 0.651-0.870), 0.595 (95% CI: 0.468-0.722), 0.508 (95% CI: 0.373-0.642), 0.847 (95% CI: 0.763-0.930), and the optimal cut-off value of the combination of 3 indexes was 0.730 which was calculated by logistic regression model formula; the corresponding sensitivity and specificity were 70.2% and 94.1%, respectively. Conclusions:The decreased level of IL-2 and increased levels of IL-6 and IFN-γ at initial diagnosis are risk factors for the onset of NHL. The combined detection of the 3 indexes shows a good value in the diagnosis of NHL.

Background::The goal of the assisted reproductive treatment is to transfer one euploid blastocyst and to help infertile women giving birth one healthy neonate. Some algorithms have been used to assess the ploidy status of embryos derived from couples with normal chromosome, who subjected to preimplantation genetic testing for aneuploidy (PGT-A) treatment. However, it is currently unknown whether artificial intelligence model can be used to assess the euploidy status of blastocyst derived from populations with chromosomal rearrangement.Methods::From February 2020 to May 2021, we collected the whole raw time-lapse videos at multiple focal planes from in vitro cultured embryos, the clinical information of couples, and the comprehensive chromosome screening results of those blastocysts that had received PGT treatment. Initially, we developed a novel deep learning model called the Attentive Multi-Focus Selection Network (AMSNet) to analyze time-lapse videos in real time and predict blastocyst formation. Building upon AMSNet, we integrated additional clinically predictive variables and created a second deep learning model, the Attentive Multi-Focus Video and Clinical Information Fusion Network (AMCFNet), to assess the euploidy status of embryos. The efficacy of the AMCFNet was further tested in embryos with parental chromosomal rearrangements. The receiver operating characteristic curve (ROC) was used to evaluate the superiority of the model. Results::A total of 4112 embryos with complete time-lapse videos were enrolled for the blastocyst formation prediction task, and 1422 qualified blastocysts received PGT-A ( n = 589) or PGT for chromosomal structural rearrangement (PGT-SR, n = 833) were enrolled for the euploidy assessment task in this study. The AMSNet model using seven focal raw time-lapse videos has the best real-time accuracy. The real-time accuracy for AMSNet to predict blastocyst formation reached above 70% on the day 2 of embryo culture, and then increased to 80% on the day 4 of embryo culture. Combing with 4 clinical features of couples, the AUC of AMCFNet with 7 focal points increased to 0.729 in blastocysts derived from couples with chromosomal rearrangement. Conclusion::Integrating seven focal raw time-lapse images of embryos and parental clinical information, AMCFNet model have the capability of assessing euploidy status in blastocysts derived from couples with chromosomal rearrangement.

Objective To investigate the efficacy and complications of one-step and two-step ultrasound-guided percutaneous transhepatic hepatic duct drainage(PTHD)in the treatment of advanced low-level biliary obstruction.Methods A total of 112 patients with advanced low-level biliary obstruction who underwent palliative surgery for reducing jaundice in the hospital from January 2019 to July 2023 were selected,and divided into the one-step group and the two-step group according to the principle of complete randomization(grouped by random number table method).The one-step group(n=56)underwent one-step PTHD,while the two-step group(n=56)underwent two-step PTHD.Surgery related indicators,serum total bilirubin(TBIL),alkaline phosphatase(ALP),alanine transaminase(ALT),the incidence of postoperative complications,and satisfaction were compared between the two groups.Results There was no difference in intraoperative blood loss[(2.96±0.50)ml vs.(3.02±0.53)ml],drainage volume in 48 hours after surgery[(555.84±90.51)ml vs.(560.52±104.23)ml]between the two groups(P＞0.05).Operation time and postoperative VAS score of the one-step group were significantly shorter/lower than those of the two-step group[(32.50±4.26)min vs.(36.43±3.58)min,(3.72±1.57)points vs.(4.53±1.34)points],and the success rate of puncture was significantly higher than that in the two-step group(96.43％vs.76.69％),with statistically significant differences(P＜0.05).After treatment,the levels of TBIL,ALP and ALT in the two groups were significantly reduced(P＜0.05),but there was no statistically significant difference between the groups(P＞0.05).There was no statistically significant difference in the incidence of complications between the two groups(3.57％vs.7.14％,Fisher's exact probability=0.679).The satisfaction rate in the one-step group was significantly higher than that in the two-step group(94.64％vs.75.00％),with a statistically significant difference(P＜0.05).ConclusionThe operation time of one-step PTHD is shorter and the success rate of puncture is higher.In addition,patients undergoing one-step PTHD have milder pain,and are more satisfied.

Objective To investigate the diagnostic value of lumbar spine CT radiomics nomogram for osteoporosis(OP).Methods A total of 414 patients who underwent abdominal CT and quantitative computed tomography(QCT)examinations were retrospectively selected.The patients were randomly divided into a training group(n=290)and a validation group(n=124)at a ratio of 7∶3.Radiomics features were extracted from lumbar spine CT images.The least absolute shrinkage and selection operator(LASSO)algorithm was used for dimen-sion reduction and feature selection.Multivariable logisitic regression was used to build the radiomics signature and the radiomics nomo-gram.The area under the curve(AUC)of receiver operating characteristic(ROC)curve was used to analyze the diagnostic performance of the Radiomics score(Radscore)and radiomics nomogram in diagnosing OP.The DeLong test was used to compare the diagnostic performance between the two models.Results Eight radiomics features were selected to establish the Radscore.The AUC of the Radscore and radiomics nomograms in the validation group for distinguishing normal bone mass from reduced bone mass and OP,reduced bone mass from OP,and OP from reduced bone mass and normal bone mass were 0.891 and 0.976,0.866 and 0.976,0.897 and 0.982,respectively.According to the DeLong test,the AUC of the radiomics nomograms was significantly higher than that of the Radscore(P＜0.05).Conclusion The radiomics nomogram model based on lumbar spine CT can serve as a novel method for individualized assess-ment of OP and provide assistance to clinical decision-making.

Objective:To translate Propensity to Achieve Healthy Lifestyle Scale (PAHLS) into Chinese and test its reliability and validity in patients with hypertension to provide the reliable assessment tool for medical staff to evaluate the propensity to achieve healthy lifestyle in hypertensive patients.Methods:This was a cross-sectional study. The original scale was translated according to Brislin model. After expert correction, cultural adjustment and pre-investigation, the items for Chinese version of PAHLS were determined. From February to May 2023, 400 patients with hypertension were selected as the participants from Tianjin Hebei District Tiedong Road Street Community Healthcare Center, Tianjin Dongli District Junliang Cheng Hospital by convenience sampling method. Critical ration and correlation analysis were used for item analysis. Content validity, exploratory factor analysis and confirmatory factor analysis were used to evaluate the validity of the Chinese version of PAHLS. Cronbach′s α coefficient and split-half reliability were used to evaluate the reliability of the scale. Results:A total of 400 patients were included in this study ultimately, aged (71.69 ± 7.25) years old, 177 males and 223 females. The Chinese version of the PAHLS included 6 items, and the results of item analysis showed that the content of each item was highly consistent with that of overall scale. The content validity indexes of the Chinese version of PAHLS at both the scale level and item level were 1. Only one factor was extracted based on exploratory factor analysis, with a cumulative variance contribution rate of 72.24%. Confirmatory factor analysis indicated a good fit, with the fitting indexes of χ2/ df=0.53, root mean square error of approximation (RMSEA)<0.01, root of mean square residual (RMR)=0.02, goodness-of-fit index (GFI)=1.00, comparative fit index (CFI)=1.00, normed fit index (NFI)=1.00, adjust goodness-of-fit index (AGFI)=0.98, incremental fit index (IFI)=1.00, Tucker-Lewis index (TLI)=1.01, Convergent validity: composite reliability (CR)=0.86 and average vriance extracted (AVE)=0.53. The overall Cronbach′s α coefficient of the scale was 0.91 and Cronbach′s α coefficients of item level were from 0.87 to 0.91, with split-half reliability value of 0.89. Conclusions:The Chinese version of the PAHLS has good reliability and validity, which can be used by medical staff to evaluate the propensity to achieve healthy lifestyle in hypertensive patients under Chinese cultural background, to increase understanding of decision-making on behavioral change in hypertensive patients and promote medical staff to jointly develop behavioral change plans with hypertensive patients.

Objective To investigate the impact of overweight on the prognosis of patients with acute mild ischemic stroke or moderate-high risk transient ischemic attack (TIA). Methods A total of 366 patients with acute mild ischemic stroke or moderate-high risk TIA who carried CYP2C19 loss-of-function alleles were included in the study. Baseline data were collected at admission, and clinical outcomes were collected within 3 months post-onset (primary outcomes: stroke recurrences within 3 months post-onset; secondary outcomes: composite outcome of stroke recurrence or death within 3 months post-onset, vascular events, and quality of life within 3 months). Kaplan-Meier method was used to plot the cumulative incidence curve of outcomes. Multivariate Cox proportional hazards model and multivariate Logistic regression model were used to evaluate the relationship between overweight and clinical outcomes within 3 months post-onset in patientswith ischemic stroke or TIA. The integrated discrimination improvement index (IDI) and net reclassification improvement index (NRI) were calculated to assess the predictive value of adding body mass index (BMI, whether overweight or not) based on traditional models for predicting the prognosis of acute ischemic stroke or TIA. Results After 3 months of follow-up, 28 patients had stroke recurrence, 1 patient died, and 31 patients had vascular events. The Kaplan-Meier cumulative incidence curve showed that the cumulative incidences of stroke recurrence, stroke recurrence or death, and vascular events after 3 months of onset were lower in overweight patients compared with non-overweight patients (Log-rank P < 0.05). Multivariate analysis showed that compared with non-overweight patients, overweight patients had significantly reduced risks of stroke recurrence within 3 months (HR=0.24; 95%CI, 0.08 to 0.71), composite outcome of stroke recurrence or death (HR=0.24; 95%CI, 0.08 to 0.69), and vascular events (HR=0.22; 95%CI, 0.07 to 0.63), and significantly improved quality of life within 3 months (OR=0.39; 95%CI, 0.20 to 0.76). The IDI and NRI calculations showed that compared with traditional models, the new model adding BMI (whether overweight) had significantly improved predictive ability for the prognosis of acute ischemic stroke or TIA. Conclusion Overweight may be a protective factor for the prognosis of TIA patients with acute mild ischemic stroke or moderate-high risk who carry CYP2C19 loss-of-function alleles. Compared with non-overweight patients, overweight patients have reduced risks of stroke recurrence, composite outcome of stroke recurrence or death, and vascular events within 3 months post-onset, and improved quality of life within 3 months post-onset.

Objective To investigate the effect of balloon bionic midwifery combined with epidural analgesia on pelvic floor function in vaginal birth after cesarean section(VBAC).Methods From January 2020 to December 2021 in Nanning Maternal and Child Health Hospital,120 cases of successful vaginal delivery after a previous cesarean section were selected as study objects,and they were divided into observation group and control group according to random number table method,with 60 cases in each group.The observation group received balloon bionic midwifery combined with epidural anesthesia during labor,while the control group received only epidural anesthesia during labor.The visual analog scale(VAS)scores,degree of perineal tear,total duration of labor,postpartum blood loss,and neonatal asphyxia rate,the incidence of urinary incontinence,vaginal or uterine prolapse,and pelvic floor muscle strength and functional status of two groups were compared.Results The total duration of labor in observation group was significantly shorter than that in control group,the amount of postpartum blood loss was significantly lower than that in control group,and the incidence of urinary incontinence was significantly lower than that in control group(P<0.05).The strength,fatigue and dynamic pressure of pelvic floor muscle in observation group were significantly better than those in control group(P<0.05).There was no significant difference in the incidence of perineal laceration or lateral incision,vaginal and uterine prolapse between two groups(P>0.05).Conclusion The use of balloon bionic midwifery combined with epidural analgesia during vaginal trial of labor after cesarean section can shorten labor duration,reduce postpartum blood loss,and improve postpartum pelvic floor function.

OBJECTIVE To study active components and antitussive effect of aboveground part of Pinellia ternata （non- medicinal stems and leaves）， and compare them with the underground part of P. ternata （medicinal underground tubers）， providing scientific basis for the comprehensive utilization and product development of P. ternata. METHODS TLC， GC， HPLC and UPLC- MS/MS were used for qualitative and quantitative analysis of amino acids， volatile oil， total flavonoids and succinic acid from the aboveground and underground parts of P. ternata. The antitussive effects of the aboveground and underground parts of P. ternata were compared and studied through cough inducing experiment with concentrated ammonia water. RESULTS Results of TLC showed that at the corresponding positions on the chromatograms of the reference substances of P. ternata， and arginine， alanine， valine， leucine and rutin control， the aboveground and underground parts of P. ternata showed spots of the same color. Results of GC showed that the similarity among characteristic chromatograms of volatile oil from aboveground and underground parts of P. ternata was 0.767； results of HPLC and UPLC-MS/MS showed that compared with underground parts of P. ternata， the contents of succinic acid， quercetin， kaempferol and isorhamnetin increased by 0.15%， 0.15%， 0.09% and 0.03%， and aspartate content decreased by 2.5 mg/g. Pharmacodynamics results showed that compared with model control group， the cough incubation period of rats was prolonged significantly in administration groups （P＜0.05）， and the cough frequency within 3 min was significantly decreased （P＜0.05）； there was no statistical significance in the cough frequency within 3 min among administration groups （P＞0.05）. CONCLUSIONS The composition of amino acids， volatile oils and total flavonoids in aboveground part of P. ternata are similar to underground part of P. ternata， while the content of aspartic acid is lower than that in underground part. The aboveground part of P. ternata can prolong the cough incubation period of rats and reduce the number of coughs， which has a certain antitussive effect， but the effect is slightly weaker than that of the underground part.
