Abstract Postoperative urinary retention is a common complication after mixed hemorrhoid surgery, referring to the inability of urine in the bladder to be normally expelled, leading to urine retention. This condition not only prolongs the postoperative recovery time and increases medical costs, but may also cause problems such as urinary tract infections and bladder dysfunction. The pathogenesis of urinary retention after mixed hemorrhoid surgery is complex, involving multiple factors such as the type of surgery, anesthesia method, individual differences among patients, postoperative pain management and psychological stress. Although there are various clinical treatment methods, their efficacy varies among individuals. This article reviews relevant literature from 2018 to 2024, analyzing the etiology of urinary retention after mixed hemorrhoid surgery. It summarizes the intervention measures and mechanisms of non-pharmacological treatments, such as physical therapy and analgesic techniques, as well as pharmacological treatments, including anticholinesterase drugs, selective α-receptor blockers and analgesics drugs, so as to provide the reference for the prevention and treatment of urinary retention after mixed hemorrhoid surgery.

The quality of measles surveillance system was not balanced among cities, and the main influencing factor was the substandard sensitivity indicators. The quality of measles surveillance system was the highest in Baoding City and the lowest in Zhangjiakou City. Conclusion The measles surveillance system in Hebei province is running well, and the sensitivity of the surveillance system should be improved to keep the high-quality operation of the surveillance system.

ObjectiveThis study aims to explore the effects of Huangqin Qingre Chubi capsules-containing serum on the expression of CircRNA_0001543/nuclear factor-kappa B （NF-κB） in co-cultured peripheral blood mononuclear cells （PBMCs） and human fibroblast-like synoviocytes （FLSs） from patients with ankylosing spondylitis （AS）. MethodsVenous blood was collected from patients with AS to isolate PBMCs. FLSs were co-cultured with AS patients' PBMCs， and FLSs were harvested after co-culture for subsequent experiments. The normal control group consisted of normal FLSs， while the model group comprised co-cultured AS PBMCs and FLSs to simulate AS pathology. The Huangqin Qingre Chubi capsules group involved adding Huangqin Qingre Chubi capsules-containing serum to the co-cultured cells（6.48 g·kg^-1）. To investigate the effect of HQC-containing serum on the viability of co-cultured cells， and the experiment was divided into the following groups based on the dilution concentration： blank group， 10% HQC group， 20% HQC group， and 30% HQC group.To study the influence of the optimal concentration of HQC-containing serum on cytokine and pathway indicators in each group， the experiment was divided into three groups： normal group， model group， and optimal concentration HQC-containing serum group.For the validation of the transfection efficiency of the CircRNA_0001543 interference plasmid， the experiment was divided into the following groups： blank group， si-NC group （with transfection reagent）， si-circ_0001543-1 group （with transfection reagent and interference plasmid No. 1 targeting circ_0001543）， si-circ_0001543-2 group （with transfection reagent and interference plasmid No. 2 targeting circ_0001543）， and si-circ_0001543-3 group （with transfection reagent and interference plasmid No. 3 targeting circ_0001543）.For the validation of the transfection efficiency of the CircRNA_0001543 overexpression plasmid， the experiment was divided into the following groups： blank group， OE-NC group （with transfection reagent）， and OE-circ_0001543 group （with transfection reagent and overexpression plasmid targeting circ_0001543）.To study the effects of CircRNA_0001543 interference/overexpression on cytokine and pathway indicators in each group， the experiment was divided into the following groups： si-NC group， si-CircRNA_0001543 group， OE-NC group， and OE-CircRNA_0001543 group. Enzyme-linked immunosorbent assay （ELISA） was used to detect levels of interleukin-1β （IL-1β）， IL-10， IL-37， and tumor necrosis factor-α （TNF-α）. Real-time quantitative polymerase chain reaction （Real-time PCR） was utilized to measure the expression of CircRNA_0001543， IκBα， and NF-κB p65. ResultsAfter 48 hours， 30% Huangqin Qingre Chubi Capsules-containing serum significantly inhibited the proliferation of co-cultured PBMCs and FLSs， which was determined to be the optimal experimental drug-containing serum concentration. Compared with those in the normal group， the expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α in the model group were significantly increased （P<0.01）， while the expressions of CircRNA_0001543 mRNA， IL-10， and IL-37 were significantly decreased （P<0.01）. Compared with those in the model group， the expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α in the Huangqin Qingre Chubi Capsules-containing serum group were significantly decreased （P<0.05）， and the expressions of CircRNA_0001543 mRNA， IL-10， and IL-37 were significantly increased （P<0.05）， with the most prominent changes in the 30% drug-containing serum group （P<0.01）. Compared with that in the si-NC group， the expression of CircRNA_0001543 was significantly reduced in the si-CircRNA_0001543 group （P<0.01）. Compared with that in the OE-NC group， the expression of CircRNA_0001543 was significantly increased in the OE-CircRNA_0001543 group （P<0.01）， indicating that the si-CircRNA_0001543 and OE-CircRNA_0001543 plasmids were successfully transfected. Based on the optimal drug-containing serum of Huangqin Qingre Chubi Capsules， si-CircRNA_0001543 transfection led to significantly increased expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α and decreased the expressions of IL-10 and IL-37 （P<0.01）. In contrast， OE-CircRNA_0001543 transfection significantly decreased the expressions of NF-κB p65 mRNA， IκBα mRNA， IL-1β， and TNF-α （P<0.01） and increased the expressions of IL-10 and IL-37 （P<0.01）. ConclusionHuangqin Qingre Chubi capsules-containing serum can improve immune inflammation in AS by increasing the expression of CircRNA_0001543， regulating the NF-κB pathway， suppressing pro-inflammatory cytokines， and enhancing anti-inflammatory cytokine expression.

Objective:To screen the main characteristic variables affecting the incidence of cardiovascular and cerebrovascular diseases,and to construct the Bayesian network model of cardiovascular and cerebrovascular disease incidence risk based on the top 10 characteristic variables,and to provide the reference for predicting the risk of cardiovascular and cerebrovascular disease incidence.Methods:From the UK Biobank Database,315 896 participants and related variables were included.The feature selection was performed by categorical boosting(CatBoost)algorithm,and the participants were randomly divided into training set and test set in the ratio of 7∶3.A Bayesian network model was constructed based on the max-min hill-climbing(MMHC)algorithm.Results:The prevalence of cardiovascular and cerebrovascular diseases in this study was 28.8％.The top 10 variables selected by the CatBoost algorithm were age,body mass index(BMI),low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC),the triglyceride-glucose(TyG)index,family history,apolipoprotein A/B ratio,high-density lipoprotein cholesterol(HDL-C),smoking status,and gender.The area under the receiver operating characteristic(ROC)curve(AUC)for the CatBoost training set model was 0.770,and the model accuracy was 0.764;the AUC of validation set model was 0.759 and the model accuracy was 0.763.The clinical efficacy analysis results showed that the threshold range for the training set was 0.06-0.85 and the threshold range for the validation set was 0.09-0.81.The Bayesian network model analysis results indicated that age,gender,smoking status,family history,BMI,and apolipoprotein A/B ratio were directly related to the incidence of cardiovascular and cerebrovascular diseases and they were the significant risk factors.TyG index,HDL-C,LDL-C,and TC indirectly affect the risk of cardiovascular and cerebrovascular diseases through their impact on BMI and apolipoprotein A/B ratio.Conclusion:Controlling BMI,apolipoprotein A/B ratio,and smoking behavior can reduce the incidence risk of cardiovascular and cerebrovascular diseases.The Bayesian network model can be used to predict the risk of cardiovascular and cerebrovascular disease incidence.

Objective:To investigate the effects of selinexor,a inhibitor of nuclear export protein 1(XPO1)on the proliferation inhibition and apoptosis of Kasumi-1 cells in acute myeloid leukemia(AML).Methods:MTS method was used to detect the inhibitory effect of different concentrations of selinexor on the proliferation of Kasumi-1 cells at different time points.The apoptosis rate and cell cycle changes after treatment with different concentration of selinexor were detected by flow cytometry.Results:Selinexor inhibited the growth of Kasumi-1 cells at different time points in a concentration-dependent manner(r24 h=0.7592,r48 h=0.9456,and r72 h=0.9425).Selinexor inhibited Kasumi-1 cells growth in a time-dependent manner(r=0.9057 in 2.5 μmol/L group,r=0.9897 in 5 μmol/L group and r=0.9994 in 10 μmol/L group).Selinexor could induce apoptosis of Kasumi-1 cells in a dose-dependent manner(r=0.9732),and the apoptosis of Kasumi-1 cells was more obvious with the increase of drug concentration.The proportion of G0/G1 phase was significantly increased and the proportion of S phase was significantly decreased after the treatment of Kasumi-1 cells by selinexor.With the increase of drug concentration,the proportion of Kasumi-1 cells cycle arrest in G0/G1 phase was increased and the cell synthesis was decreased.Conclusion:Selinexor can promote the death of tumor cells by inhibiting Kasumi-1 cells proliferation,inducing apoptosis and blocking cell cycle.

Objective:To explore whether Ph+acute lymphoblastic leukemia (ALL)cell line SUP-B15 treated with imatinib occurs a tolerant status charactered by cell proliferation suppression but apoptotic resistance,then evaluate whether IGF1-R inhibitor AEW541 can break this tolerance,and further explain its mechanisms.Methods:SUP-B15 cells were treated with different concentrations of imatinib or AEW541.Cell proliferation was assayed by Deep Blue,and apoptotic cells were determined by Annexin V/7-AAD staining.Apoptotic rate was measured by flow cytometry after co-treatment of imatinib and AEW541.Western blot was used to evaluate ABL downstream signals,including the phosphorylation of STAT5,ERK1/2,and AKT,as well as to detect cleaved caspase-3 and PARP1,the molecular signatures of apoptosis.Furthermore,an inhibitor of STAT5 or MEK-ERK1/2 was used to confirm the key mechanism of the combination of imatinib and AEW541 induced SUP-B15 cell apoptosis.Results:Imatinib monotherapy effectively suppressed the proliferation of SUP-B15 cells,but did not induce significant increase of apoptotic rate,leading to occurrence of tolerant status.AEW541 monotherapy did not dramatically affect the proliferation and apoptosis of SUP-B15 cells,but significantly increased apoptotic rate of SUP-B15 cells and cleavage of caspase-3 and PARP1 when combined with imatinib simultaneously. A combination of imatinib and AEW541 reduced STAT5 and ERK1/2 phosphorylation as compared with imatinib monotherapy in SUP-B15 cells,but had no impact on AKT phosphorylation.Apoptosis could be induced by STAT5 inhibitor AC-4-130,but not by MEK-ERK1/2 inhibitor trametinib in SUP-B15 cells.Conclusion:SUP-B15 cells treated with imatinib can establish drug tolerance.IGF1-R inhibitor AEW541 can further reduce STAT5 activation,thereby boosting the effect of apoptotic induction of imatinib on SUP-B15 cells.This research may provide a new idear to overcome imatinib tolerance.

Objective:To explore the status of osteoporosis in patients with ankylosing spondylitis in the Han and four other ethnic minorities in Xinjiang.Methods:From January 2019 to June 2020, 89 patients with ankylosing spondylitis who were hospitalized in the Rheumatology and Immunology Department of the First Affiliated Hospital of Xinjiang Medical University with complete data were collected. Age, sex, body mass index, course of the disease, blood calcium, phosphorus, alkaline phosphatase, 25 hydroxy-vitamin D 3 level, Creactive protein, erythrocyte sedimentation rate, human leukocyte antigen B27, family history, peripheral joint involvement were analyzed between Han and ethnic minority patients. Extra-articular manifestations, presence or absence of fracture, and bone mineral density were analyzed with SPSS 26.0. Quantitative data were described using s and independent sample t-test. Counting data was described using n (%) and Pearson χ2 test. The rank sum test was used for econometric data and grade data that were not meet with normal distribution. Results:Among the 89 patients, 46 were Han and 43 were ethnic minorities, with an average age of (37.2±8.4) years. Seventeen patients had osteoporosis, of which 7 were Han and 10 were ethnic minorities. The mean age was (34.2±10.4) years. and the course of disease was (11.6±4.9)months. Among the patients with osteoporosis, the age of ethnic minority patients was younger [ethnic minority (25.4±10.7)years vs. Han (37.8±10.5)years, t=2.48 , P=0.021], and the duration of disease was shorter (month) [ethnic minority (5.4±2.6)months vs. Han (8.5±2.0)months, t=2.63 , P=0.015]. Conclusion:Although ankylosing spondylitis is mainly in young people, osteoporosis is not uncommon. Ethnic minority patients with ankylosing spondylitis complicated with osteoporosis are younger in age and shorter in course of disease than Han patients.

Objective:To establish an artificial intelligence-based surgical selection system utilizing deep learning to assist in the decision-making process for lumbar endoscopic surgery.Methods:General data of 1,110 patients who underwent percutaneous transforaminal endoscopic discectomy, 804 patients who underwent percutaneous interlaminar endoscopic discectomy, 923 patients who underwent mobile microendoscopic discectomy and 623 patients who underwent unilateral biportal endoscopic in Tianjin Hospital from January 2018 to June 2023 were included in the study. Clinical outcomes were assessed using the visual analogue scale (VAS) for leg and back pain, the Oswestry disability index (ODI), and MacNab criteria both before surgery and 12 months postoperatively. Using a random number table method, patients were divided into a training dataset (2,768 cases) and a test dataset (692 cases) at a ratio of 4∶1. Patient clinical symptoms, physical signs, and multi-modal imaging data were input into a deep learning model. This model was structured into three main modules: intervertebral disc detection, surgical necessity identification, and surgical recommendation. The final surgical method was determined using a convolutional neural network incorporating U-Net for segmentation and ResNet for classification. The accuracy and recall rates of each module were evaluated using the test dataset.Results:Compared to preoperative values, all patients showed significant improvements at the 12-month postoperative follow-up. For patients who underwent percutaneous transforaminal endoscopic discectomy, percutaneous interlaminar endoscopic discectomy, mobile microendoscopic discectomy, and unilateral biportal endoscopic surgery, the VAS scores for leg pain decreased from 7.69±0.80, 7.82±0.88, 7.62±0.69, and 7.56±1.00 preoperatively to 1.44±1.09, 1.35±0.82, 1.51±1.08, and 1.43±0.91 postoperatively. Similarly, the VAS scores for back pain decreased from 5.73±0.83, 6.17±0.99, 6.11±0.88, and 6.46±0.95 to 0.93±0.75, 1.01±0.67, 1.40±0.72, and 1.27±0.70, respectively. Additionally, the ODI significantly decreased from 39.91%±4.50%, 40.05%±8.05%, 47.08%±9.50%, and 44.43%±4.71% preoperatively to 5.77%±2.22%, 6.05%±2.31%, 8.51%±2.16%, and 9.51%±3.70% postoperatively, with all differences being statistically significant ( P<0.05). The excellent rate according to the MacNab criteria was 93.12% (3,222/3,460). In the deep learning model, the multi-modal data of 2,768 patients were input in the training set for deep learning to form a surgical identification and operation recommendation system, and the preoperative data of 692 patients were input in the test set to compare with the final operation method. In the intervertebral disc location module, the accuracy of location and designation of the five lumbar intervertebral discs was 97.1%(672/692). In the module of intervertebral disc need for surgery, the accuracy was 94.8%(3,280/3,460) and the recall rate was 91.9%(636/692). As for patients, the accuracy rate was 91.9%(636/692). In the operation recommendation module, the accuracy rate of operation recommendation based on intervertebral disc was 89.5%(569/636), and the accuracy rate of surgical recommendation based on patient was 82.2%(569/692). Conclusion:In this study, an artificial intelligent surgical procedures selection system based on deep learning was established, which could effectively integrate relevant data and accurately guide the selection of lumbar endoscopic surgery.

Objective:To evaluate the feasibility and safety of PT Scope (short for intelligent pressure and temperature controlled flexible ureteroscopy)combined with Thulium laser in the intracavitary treatment of upper urinary tract stones.Methods:A retrospective analysis was conducted on the clinical data of 13 patients with upper urinary tract stones who were treated with PT Scope combined with Thulium laser lithotripsy in Sun Yat-Sen Memorial Hospital from February to April 2024. There were 7 males and 6 females. The patients had a mean age of (46±10) years old, with an accumulated stone diameter of (25.8±13.3) mm. There were 7 cases of lower calyx stones (53.8%), and 3 cases of concomitant ureteral stones (23.1%).Four patients (30.8%) had positive preoperative urine cultures, and six patients (46.2%) had leukocyte counts greater than 100 cells/μl in their urine tests. The Thulium laser power was set at 45 W (1.5 J at 30 Hz, 0.3 J at 150 Hz). The renal pelvic pressure threshold was set at 30 mmHg (1 mmHg=0.133 kPa), and the temperature threshold at 43 ℃. Postoperatively, double J stents were placed for 2 to 4 weeks.Results:All 13 patients successfully completed the surgery. The median operative time was 30 (25, 90) minutes. The intraoperative average renal pelvic pressure in these 13 patients ranged from 8 mmHg to 24 mmHg, and the average renal pelvic temperature ranged from 25 ℃ to 34 ℃. Postoperatively, 1 patient experienced a fever (38.0 ℃) and 2 patients required analgesic treatment due to postoperative pain. There were no other intraoperative or postoperative complications. The median postoperative hospital stay was (1.5±0.8) days. The stone-free rate of 1 month was 84.6%(11/13).Conclusions:PT Scope combined with Thulium laser could effectively control renal pelvic pressure and temperature, achieve a high stone-free rate, and have a low complication rate. It is a safe and effective treatment for upper urinary tract stones.
