Objective To investigate the diagnostic value Tamm-Horsfall protein(THP)and osteopontin(OPN)in serum and 24-hour urine for urolithiasis.Methods A total of 101 patients with urolithiasis who underwent flexible ureteroscopy lithotripsy at the Urology Department of Civil Aviation General Hospital from April 2020 to March 2023 were included as the stone group,and 50 healthy individuals were enrolled as the control group.The samples of serum and 24-hour urine samples were collected from both the groups,and the levels of THP and OPN were measured using enzyme-linked immunosorbent assay(ELISA).Logistic regression analysis was performed to evaluate the association between each biomarker and urolithiasis,and receiver operating characteristic(ROC)curves were plotted to assess their diagnostic value.Results The stone group showed significantly lower THP levels(20.13[13.12,26.03]mg/d)and OPN levels(51.24[36.72,101.37]μg/d)in 24-hour urine,and THP levels(182.01[160.91,209.20]ng/mL)and OPN lev-els(18.76[15.72,22.48]ng/mL)in serum compared to the control group(all the P＜0.001).Binary Logistic regression analysis re-vealed that THP(OR=0.736,95％CI:0.606-0.895),OPN(OR=0.975,95％CI:0.958-0.993)and citrate(OR=0.067,95％CI:0.012-0.376)in 24-hour urine,and THP(OR=0.946,95％CI:0.908-0.986)and OPN(OR=0.896,95％CI:0.803-0.999)in ser-um were the protective factors for urolithiasis,while calcium level(OR=2.125,95％CI:1.243-3.633)24-hour urine was a risk factor(all the P＜0.05).ROC curve analysis showed that the areas under the curve(AUCROC)for the individual diagnosis of urolithiasis were 0.846,0.809,0.786,0.823,0.748,and 0.755 for the above six biomarkers,respectively.The AUCROC for the combined diagnosis u-sing THP+OPN in serum,THP+OPN in 24-hour urine and all the six biomarkers were 0.882,0.920 and 0.984,respectively,indica-ting better diagnostic performance.Conclusion The combined detection of the THP and OPN levels in serum and 24-hour urine may have good diagnostic value for urolithiasis and serve as potential diagnostic biomarkers.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To evaluate the effects of ultrasound-guided quadratus lumborum block (QLB) on acute pain after total hip arthroplasty.Methods:A retrospective study was conducted of the 36 patients with hip osteoarthritis who had undergone selective one-side total hip arthroplasty under total intravenous anesthesia (TIVA) from January 2019 to January 2020. According to whether additional QLB was used or not they were divided into 2 equal groups ( n=18). The control group of 10 males and 8 females with an age of 60.5±9.4 years used mere TIVA while the QLB group of 7 males and 11 females with an age of 53.6±12.7 years used TIVA plus QLB. All patients accepted patient-controlled intravenous analgesia (PCIA) postoperatively. The 2 groups were compared in terms of visual analogue scale (VAS) at rest and during exercise and IL-6 level at 24 h postoperation, consumption of opioids and postoperative incidence of nausea and vomiting. Results:There were no significant differences between the 2 groups in their preoperative general data, indicating they were compatible ( P>0.05). The VAS scores at rest and during exercise in the QLB group (0.3 ± 0.5 and 0.8 ± 0.6) were significantly lower than in the control group (2.1 ± 0.7 and 2.7 ± 0.5), the IL-6 level in the former[40.9 (30.5, 56.3) pg/mL] was significantly lower than in the latter[165.0 (82.5, 276.5) pg/mL], the intraoperative total consumptions of sufentanil[6 (6, 7) μg] and remifentanil[1,370 (1,200, 1,485) μg] in the former were significantly lower than in the latter[35 (30, 40) μg and 1, 910 (1, 805, 2, 000) μg], and the postoperative incidenceof nausea and vomiting[27.8%(5/18)] in the former was significantly lower than in the latter[77.8%(14/18)] (all P<0.05). Conclusions:Ultrasound-guided quadratus lumborum block can effectively relieve acute pain in patients after total hip arthroplasty. It can suppress stress-related inflammatory factors, reduce consumption of opioids and incidence of postoperative nausea and vomiting.

Objective To investigate the prevalence and associated risk factors for pterygium among people aged 50 years and above in Funing County,Jiangsu Province.Methods A cluster random sampling method was performed,the subjects aged 50 years or above were randomly selected from 30 survey sites in Funing County,Jiangsu Province.Questionnaires,visual acuity tests,the examinations of eye surface,anterior segment,fundus examinations were conducted.Pterygium was diagnosed and graded clinically by slit lamp examination.The risk factors were acquired from questionnaires and analyzed by the multivariate logistic regression analysis.This study protocol was approved by Ethic Committee of Affiliated Hospital of Nantong University (NO.2010-05).Written informed consent was obtained from each subject prior to entering study cohort.Results A total of 6 145 persons aged 50 years and above were enumerated,and actually 5 947 (96.8％) participants were examined.Among them,1 950 cases were diagnosed as pterygium in either eye and 1 228 cases were diagnosed as pterygium in binoculus,which was equivalent to the 32.79％ [95％ confidence interval(CI):31.60％-33.98％] of pterygium in either eye and 20.65％ (95％ CI:19.62％-21.68％) in bilateral pterygium.Among 2467 male subjects,838 were diagnosed as pterygium (33.97％,95％ CI:32.10％-35.84％).Among 3480 female subjects,1 112 were diagnosed as pterygium (31.95％,95％ CI:30.40％-33.51％).There was no significant difference in the prevalence of pterygium between genders (P =0.135).Multivariate Logistic analysis showed that,older age (50 ～ ＜60 years:odds ratio [OR] =1.00;60 ～ ＜70 years:OR=1.54,P＜0.001;70 ～ ＜80 years,OR=1.83,P＜0.001;≥80 years:OR=1.99,P＜0.001),low educational level (no education:OR =1.00;＜primary:OR =0.87,P =0.031;primary education:OR =0.72,P =0.002;≥ secondary education:OR =0.63,P =0.002),farmer occupations (OR =1.34,P =0.020),and long outdoor work time (OR =1.13,P =0.026) were independent risk factors for pterygium.Gender,marriage,income,hypertension,diabetes,smoking and alcohol use history were not associated with pterygium (all at P＞0.05).Conclusions The prevalence of pterygium in Funing County is 32.79％ in people aged 50 years and above.The high prevalence of pterygium may be associated with older age,low education level and long outdoor work time.

Objective To evaluate the inductive effect of interferon-γ(IFN-γ) combined with tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) on programmed necrosis of the human immortalized keratinocyte cell line HaCaT,and to explore its mechanisms.Methods In vitro cultured HaCaT cells were divided into several groups:negative control group receiving no treatment,IFN-γ group treated with 50 μg/L IFN-γ,TRAIL group treated with 4 μg/L TRAIL,and cytokine combination group treated with 50 μg/L IFN-γ and 4 μg/L TRAIL or zVAD combination group pretreated with 40 μmo/L zVAD for 1 hour followed by the treatment with 50 μg/L IFN-γand 4 μg/L TRAIL.After 48-hour treatment,the morphology of HaCaT cells were observed under a light microscope,methyl-thiazolyl-tetrazolium assay was performed to evaluate the inhibitory effect of the treatment on the proliferation of HaCaT cells,and double staining flow cytometry to detect the necrosis of HaCaT cells.Meanwhile,real-time fluorescence-based quantitative PCR (qPCR) was conducted to determine the mRNA expression of receptor interaction protein kinase 3 (RIP3) and mixed lineage kinase domain-like protein (MLKL),Western blot analysis to determine the expression of RIP1,RIP3,MLKL proteins and their phosphorylated forms (pRIP1,pRIP3,pMLKL),immunofluorescent staining to observe the distribution of pRIP3 and pMLKL in HaCaT cells,and the level of reactive oxygen species (ROS) in HaCaT cells in the above groups was detected by the fluorescence probe DCFH-DA.Statistical analysis was carried out with SPSS 22 software by using one-way analysis of variance (ANOVA) for comparing indices among different groups,and least significant difference (LSD)-t test for multiple comparisons.Results After 48-hour treatment,HaCaT cells in the cytokine combination group and zVAD combination group showed necrosis-like morphologic features.Methyl-thiazolyl-tetrazoliumassay revealed significant differences in the survival rate of HaCaT cells among the IFN-γgroup,TRAIL group,cytokine combination group,zVAD combination group and negative control group (73.16％ ± 5.71％,81.46％ ± 4.68％,72.18％ ± 2.93％,69.67％ ± 3.24％ and 100％,respectively;F =24.34,P ＜ 0.001).The necrosis rate of HaCaT cells was notably higher in the cytokine combination group and zVAD combination group (9.86％ ± 1.31％,10.33％ ± 2.16％,respectively) than in the negative control group (5.26％ ± 0.91％,t =4.61,5.07,respectively,both P ＜ 0.05).qPCR revealed that the mRNA expression of RIP3 and MLKL significantly increased in the cytokine combination group and zVAD combination group compared with the negative control group (tRIP3 =0.99,1.84,tMLKL =1.51,2.17,respectively,all P ＜ 0.05).Western blot analysis suggested that the protein expression of RIP1,RIP3,MLKL,pRIP1,pRIP3 and pMLKL significantly increased in the cytokine combination group compared with the negative control group (all P ＜ 0.05),and the zVAD combination group showed significantly decreased caspase 8 expression and increased expression of the above proteins compared with the cytokine combination group.Fluorescence microscopy showed that enhanced green dot-like or clump-like fluorescent spots (representing pRIP3) could be observed in the cytoplasm,and red fluorescent spots (representing pMLKL) could be seen on the cell membrane in the cytokine combination group.The average fluorescence intensity of ROS was significantly higher in the cytokine combination group than in the negative control group (t =702.00,P ＜ 0.05).Conclusion IFN-γcombined with TRAIL can induce the programmed necrosis of HaCaT cells with increased level of ROS.

Objective To investigate the clinical features of cerebral venous sinus thrombosis (CVST)in patients with malignancy as well as its underlying pathogenesis. Methods The clinical data, including clinical presentation, laboratory results, neurological images were retrospectively reviewed in hospital patients with active malignant tumor and cerebral venous thrombosis from January 2006 to December 2016. Results Among the 586 CVST patients, 24 patients (4.10%) were with malignant tumor. Among these 24 patients, there were 8 males and 16 females with an average age of (39.88 ± 21.71) years old. Four patients (16.67%) had the risk factors of cerebral venous sinus thrombosis, while the other 20 patients(83.33%)had not any such risk factors.At the symptom onset of CVST, 22 patients(91.67%) had headache and focal neurological deficit, such as limbs weakness and numbness. The common substyles of malignant tumor were lung cancer (33.33%), breast cancer (29.17%)and acute lymphocytic leukemia(20.83%).Most patients(58.33%)were found to have cerebral metastasis.22 patients (91.67%) had elevated plasma D-dimmer level, and 19 patients (79.17%) had elevated plasma cancer biochemical marker levels.Conclusions Cancer-related CVST had the features including lacking conventional risk factors, elevated plasma D-dimmer and cancer biochemical marker levels.Cerebral metastasis and hypercoagulable state may be responsible for the pathogenesis of CVST.

Objective: To investigate the reproductive health status of female workers in a railway system and possible influencing factors. Methods: From January to June, 2016, a cross-sectional epidemiological investigation was performed to collect 2 165 female workers aged 17-55 years. A women’s health questionnaire was used to collect the data on their occupation and health, and their reproductive health status was analyzed. Results: The female workers exposed to occupational hazards had significantly higher incidence rates of gynecological diseases, abnormal menstruation, and infertility than those not exposed to such hazards (χ²=32.29, 12.42, and 4.23, respectively, all P<0.05) . There were significant differences in the incidence rates of gynecological diseases, abnormal menstruation, adverse pregnancy outcomes, and pregnancy complications between the female workers with different working forms and states (χ²=17.19, 23.03, 200.65, and 21.28, respectively, all P<0.05) . There were significant differences in the incidence rates of gynecological diseases, abnormal menstruation, and pregnancy complications between the female workers with different behavioral habits (χ²=15.65, 36.23, and 25.35, respectively, all P<0.05) . The logistic regression analysis showed that exposure to occupational hazards, married state, medium-grade professional title or above, work in shifts, sitting for a long time, standing for a long time, and video operation were risk factors for gynecological diseases, and the prevalence rate of gynecological diseases increased with age. Exposure to occupational hazards, night shifts, staying up late, and sitting for a long time were risk factors for abnormal menstruation. Exposure to occupational hazards was a risk factor for infertility. Medium-grade professional title or above was a risk factor for adverse pregnancy outcomes. Married state, medium-grade professional title or above, standing for a long time, and high mobility in job form and state were risk factors for pregnancy complications. Conclusion Exposure to occupational hazards, job form and state, and unhealthy behavioral habits may affect reproductive health status in female workers in the railway system.

Objective To study the clinical features and possible pathogenesis of acute ischemic stroke in renal cell cancer patients. Methods The clinical data from in-hospital patients with renal cell cancer who developed acute ischemic stroke were collected, including the patients with renal cell cancer who developed acute ischemic stroke during anti-cancer therapies and those patients with acute ischemic stroke who were firstly diagnosed to have renal cell cancer during anti-stroke therapies between January 2003 and December 2015. Results A total of 2516 patients with renal cell cancer were screened, and there were 36 patients (1.43%) with acute ischemic stroke. Out of the 36 patients, there were 29 men (80.56%) and 7 women (19.44%). Their age ranged from 45 to 68 years, with a average age of (65.11 ± 14.77) years. Eight patients (22.22%) had some conventional cardiovascular risk factors, while the other 28 patients (77.78%) had no such risk factors. Magnetic resonance imaging (MRI) scans at the acute stage of ischemic stroke were carried out for all these patients. Based on the diffusion weighted imaging (DWI) of MRI, 8 patients (22.22%) had single lesion and 28 patients (77.78%) had multiple lesions in different arterial territories in their brains. The pathological types of renal cell cancer were:suprarenal epithelioma (18 patients, 50.00%), papillary cell carcinoma (12 patients, 33.33%) and chromophobe renal cell carcinoma (6 patients, 16.67%). Metastases were found 10 patients (27.78%) out of the 36 patients. Blood biochemical examination showed that 28 patients had elevated plasma D-dimer level, 22 patients had elevated plasma cancer antigen (CA)125 level, and 17 patients had elevated plasma carcinoembryonic antigen (CEA) levels. Conclusions It is suggested that the renal cell cancer associated stroke is characterized by lacking of traditional risk factors and having multiple lesions in brain;and that the elevated plasma D-dimer, CA125 and CEA levels may lead to hypercoagulable state and lead to ischemic stroke eventually .
