BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA

Threatened abortion is a common disease of obstetrics and gynecology and one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in TCM obstetrics and gynecology， Western medicine obstetrics and gynecology， and pharmacology to deeply discuss the advantages of TCM and integrated Chinese and Western medicine treatment as well as the medication plans for threatened abortion. After discussion， the experts concluded that chromosome， endocrine， and immune abnormalities were the key factors for the occurrence of threatened abortion， and the Qi and blood disorders in thoroughfare and conception vessels were the core pathogenesis. In the treatment of threatened abortion， TCM has advantages in preventing miscarriages， alleviating clinical symptoms and TCM syndromes， relieving anxiety， regulating reproductive endocrine and immune abnormalities， personalized and diversified treatment， enhancing efficiency and reducing toxicity， and preventing the disease before occurrence. The difficulty in diagnosis and treatment of threatened abortion with traditional Chinese and Western medicine lies in identifying the predictors of abortion caused by maternal factors and the treatment of thrombophilia. Recurrent abortion is the breakthrough point of treatment with integrated traditional Chinese and Western medicine. It is urgent to carry out high-quality evidence-based medicine research in the future to improve the modern diagnosis and treatment of threatened abortion with TCM.

Objective:To analyze clinical characteristics of primary pancreatic lymphoma (PPL) patients.Methods:Clinical features of 22 patients diagnosed as PPL admitted to Peking Union Medical College Hospital from January 2002 to May 2023 were analyzed retrospectively.Results:The median age was 56.4±13.3 years. The median time from onset to diagnosis was 1.0 (1.0, 3.0) months. The main clinical manifestations were abdominal pain (15/22), weight loss (14/22) and jaundice (10/22). Elevated lactate dehydrogenase (LDH) was observed in 15/20 (75%) patients. Only 2 (2/9, 22.2%) patients had increased CA199 levels and 2 (2/9, 22.2%) patients had increased CEA levels. The maximum tumor diameter was 5.0 (3.8, 6.9) cm. Contrast-enhanced CT mostly showed low enhancement lesions. Major pancreatic duct dilatation were rare on CT scan (4/20). Fifteen patients were confirmed by pancreatic pathology, of which 8 were obtained by surgery, 4 were obtained by CT or ultrasound-guided percutaneous biopsy, and 3 were obtained by EUS-FNA. The main pathological type was diffuse large B-cell lymphoma (14/22). 19 patients received chemotherapy, and 6 patients died with a median follow-up of 5.0 (1.5, 35.5) months.Conclusions:PPL is rare and easy to be misdiagnosed. Elevated LDH levels, normal tumor markers, and non-dilatation of main pancreatic duct are important diagnostic clues. It is important to obtain pathology by EUS-FNA and other methods for definite diagnosis.

Objective To investigate the clinical values of heparinase-modified thromboelastography(hmTEG)in heparin monitoring during continuous renal replacement therapy.Methods A total of 97 cases who were undergoing continuous renal replacement therapy(CRRT)in the intensive care unit of the 94th People's Liberation Army Hospital from Jan 2014 to Jun 2019 were enrolled in this stud-y.The patients were divided into TEG group and APTT group according to different means of heparin monitoring during continuous renal replacement therapy.In total,278 hemofilters were used in all the blood purification therapies.Complication of bleeding,CRRT time,total heparin dose and SOFA(sequential organ failure assessment)score of the patients were compared between the TEG and APTT groups.The filter life span and survival time in hospital were also compared using Kaplan-Meier analysis.Rusults Compared with APTT group,the total heparin dose in TEG group were significantly higher(P＜0.05).The CRRT time of patients and the average filter life span in TEG group were significantly longer than those of APTT group(P＜0.05).Compared to APTT group,the 28-day SOFA in TEG group was significantly lower(P＜0.05).Survival analysis showed that the 28-day risk of death in the patients of APTT group was 2.01 times higher than that in TEG group(P＜0.05).The 72-hour filter life of TEG group was significantly longer than that of APTT group(P＜0.05).Conclusion The use of hmTEG for monitoring heparin in blood purification should be superior in terms of safety and efficacy with longer filter life span and higher survival rate of patients.

The present study aims to explore the genetic diversity of germplasm resources of Chrysanthemum×morifolium (hereinafter, C.×morifolium) at the molecular level and to establish a fingerprint database of C.×morifolium varieties. We employed 12 pairs of primers with high levels of polymorphism, clear bands, and high degrees of reproducibility to analyze the SSR molecular markers and genetic diversity of 91 C.×morifolium materials and 14 chrysanthemum- related materials. With regard to constructing the fingerprints of the tested materials, we chose 9 pairs of core primers. The findings revealed that 12 primer pairs detected 104 alleles in 105 samples, ranging from 2 to 26. The average number of observed alleles (N_a) per site was 9.25. The average number of effective alleles (N_e) per site was 2.745 6, with its range being 1.276 0 to 4.742 5. Shannon genetic diversity index (I) values ranged between 0.513 3 and 2.239 9 (M=1.209 0). Nei's gene diversity index (H) ranged between 0.216 3 and 0.789 1 (M=0.578 0). The observed heterozygosity (H_o) ranged between 0.223 3 and 0.895 2 (M=0.557 5). The expected heterozygosity (H_e) ranged between 0.217 4 and 0.793 3 (M=0.580 8). The polymorphism information content (PIC) ranged between 0.211 5 and 0.774 0 (M=0.532 9). The genetic similarity (GS) ranged between 0.228 5 and 1.000 0 (M=0.608 3). Cluster analysis revealed that when the genetic distance (GD) equals to 0.30, the tested materials can be classified into 2 groups. When the GD equals to 0.27, the first group can be divided into 6 subgroups; accordingly, 105 tested materials can be divided into 7 subgroups. The cophenetic correlation test was carried out based on the cluster analysis, and the corresponding results showed that the cluster map correlated with the genetic similarity coefficient (r=0.952 73). According to the results of Structure population analysis, we obtained the optimal population number, with the true number of populations (K) being 3 and the population being divided concerning Q≥0.5. Three subgroups, i.e., Q1, Q2 and Q3, included 34, 33 and 28 germplasms, respectively, and the remaining 10 germplasms were identified as the mixed population. During the experiment, 9 pairs of core primers were screened among the total of 12 for a complete differentiation regarding 105 tested materials, and the fingerprints of 91 C.×morifolium materials and 14 chrysanthemum-related materials were further constructed. Overall, there were significant genetic differences and rich genetic diversity among C.×morifolium materials, which would shed light on the garden application and variety selection fields of C.×morifolium. The fingerprint database of 105 C.×morifolium varieties and chrysanthemum-related species may provide technical support for future research regarding the identification and screening system of C.×morifolium varieties.

Objective:To investigate the clinical significance of plasma thrombin-antithrombin complex (TAT) levels in patients with sepsis-induced cardiomyopathy(SIC).Methods:One hundred and seven sepsis patients who were admitted to intensive care units (ICU) of the 908th Hospital of Chinese PLA Logistical Support Force were enrolled in the study. Patients were divided into sepsis group ( n=79) and the sepsis-induced cardiomyopathy group ( n=28) according to whether the cardiac ultrasound examination in 2 hours after admission, and the differences of each indicators between the two groups were compared including acute physiological and chronic health score (APACHEⅡ), lactate, blood routine, liver and kidney function, cardiac troponin I, N-terminal?pro-brain?natriuretic?peptide (NT-pro BNP), conventional coagulation tests and molecular markers of coagulation [tissue plasminogen activator-inhibitor complex (t-PAIC), thrombomodulin (TM), TAT, plasmin-α2-plasmin inhibitor complex (PIC)].Logistical?regression?was?used?to analyze the?risk?factors?for sepsis-induced cardiomyopathy and the receiver operating characteristic (ROC) curve was to analyze their cut-off values. The effect of low-molecular-weight heparin anticoagulation therapy on sepsis patients with TAT>8.26 ng/ml was evaluated by Kaplan-Meier analysis. Results:Compared with the cardiac troponin I[0.02(0.01, 0.09) ng/ml], NT-proBNP [1 118.09 (333.25, 2687.00) pg/ml], lactate[1.35(0.90, 2.60) mmol/L], TAT[6.50(3.94, 12.14) ng/ml], PIC[1.256 (0.668, 2.045) μg/ml] and t-PAIC[10.50 (6.70, 21.30) ng/ml] in sepsis group, the cardiac troponin I [0.75(0.01, 6.02) ng/ml], NT-proBNP[12 125.14(4 185.89, 33 611.62) pg/ml], lactate[2.35(1.43, 4.34) mmol/L], TAT[19.85 (9.08, 45.78) ng/ml], PIC[2.115 (0.878, 4.114) μg/ml] and t-PAIC [22.03(15.61,33.20) ng/ml] levels in the sepsis-induced cardiomyopathy group were significantly increased ( P<0.05). Logistical regression showed that positive NT-pro BNP and elevated TAT levels were independent risk factors for sepsis-induced cardiomyopathy. ROC curve analysis showed that the area under the curve of plasma TAT level for predicting sepsis-induced cardiomyopathy was 0.78. The sensitivity and specificity at the cut-off value of plasma TAT level with 8.26 ng/ml were 0.82 and 0.63, respectively. Conclusions:The elevated TAT level was an independent risk factor for the development of sepsis-induced cardiomyopathy. Low-molecular-weight heparin anticoagulation therapy can improve the 28-day survival rate of sepsis patients with TAT>8.26 ng/ml.

Objective:To investigate changes in the bladder morphological structure and function and the expression of transforming growth factor-beta1 (TGF-β1) pathway-related proteins in the bilateral spinal nerve amputated neurogenic bladder(NB) rat.Methods:A total of 64 female SD rats were included, and 32 of them underwent bilateral spinal nerve L6+ S1 amputation to construct the NB model and the others were used as sham operation controls.Rats in both NB and control groups received bladder cystometry 3, 6, 12, 24 weeks after corresponding operation.Collagen fibers in their bladder tissues were detected by Masson staining and Sirius scarlet staining.TGF-β1, Smad2 and Smad6 proteins were checked by immunohistochemical staining.TGF-β1 receptor Ⅰ protein was measured by Western blot.Results:Bladders in the NB group were instable, with bladder leak point pressure(BLPP) and underactive voiding pressures.The basal pressure [(22.10±2.51), (18.20±1.52), (31.20±2.82), (41.10±3.41) cmH 2O(1 cmH 2O=0.098 kPa)] and bladder volume [(22.30±1.72), (49.10±5.54), (30.30±2.68), (13.50±1.52) mL] of the NB rats at 3, 6, 12 and 24 weeks were significantly higher than those of the sham operation controls[(3.51±0.45) cmH 2O and (0.52±0.04) mL], and the difference were significant(all P<0.05). The bladder size and thickness in the NB group firstly increased (3, 6 weeks) and then decreased (12, 24 weeks), but the bladder weight increased continuously.Masson staining showed disordered fibrous connective tissues, disintegrated layered bla-dder wall, hypertrophied smooth muscle tissues and deposited intramuscular collagen on the nerve-amputated bladder wall.Sirius scarlet staining suggested that 24 weeks after nerve amputation, collagen Ⅲ increased greatly, and the ratio of type Ⅲ/Ⅰ collagen fibers (3.14±0.71) was significantly higher than that in the sham group (0.88±0.21) ( t= 7.48, P<0.01). According to the immunohistochemical staining results, the expressions of TGF-1β and Smad2 increased while the pathway inhibitory protein Smad6 decreased with time in the NB group.Western blot showed that the expression of TGF-β1 receptor Ⅰ in the amputated bladder was 1.3 and 1.6 folds higher than that in the sham group 12 weeks and 24 weeks after operation( t=6.06, 14.45, all P<0.01). Conclusions:In NB rats with bilateral spinal nerve amputated, bladder contraction becomes paralysis, intravesical pressure increases, bladder normal structure disintegrates and the fibrosis pathway TGF-β1/Smads is activated.Therefore, the key step of development of pediatric NB is bladder fibrosis, which should be prevented as early as possibly in the clinical practice.

Objective:To investigate the effects and mechanism of cystostomy on young rats′ bladders function.Methods:Eighty female SD rats were divided into cystostomy group, sham operation group (the two groups included day 1, 3, 5 after operation), control group(it included day 1, 3, 5 after operation) and medicine intervention group by using random number table, there were 8 rats in each group.Cystometry was conducted in cystostomy group (day 1, 3, and 5 postoperative subgroup), and voided interval (VI), voided volume (VV), postvoid residual urine (PVR), bladder capacity (BC), maximum bladder pressure (Pves.max), bladder threshold pressure (Pves.thr), and bladder compliance(△C) were recorded.The rats in sham operation and control groups voided freely in the condition of diuresis by intravenous infusion saline, and VV, PVR and BC were recorded.Bladders′ tissues were collected for HE staining and histopathological inflammation scores (HIS) after urodynamic investigations.In medicine intervention group, different doses of anisodamine were applied and the changes of VI, VV, PVR, BC, Pves.max and Pves.thr were observed.Results:The trend of VV, VI, BC and △C was upwards on days 1, 3, and 5 postcystostomy.Meanwhile, compared with control group [VV: (1.408±0.033) mL, BC: (1.411±0.032) mL], VV and BC on day 1 and 3 postcystostomy were less[VV: (0.288±0.059) mL, (0.598±0.154) mL; BC: (0.292±0.059) mL, (0.601±0.154) mL]. There were statistically significant differences ( P<0.05). However, VV, PVR and BC on day 5 postcystostomy were not different from that of control group(all P>0.05). HE staining demonstrated that the HIS of days 1 and 3 postcystostomy and day 1 post-sham operation were in severe inflammatory phase, with HIS >4 scores.Additionally, the inflammation on day 5 in cystostomy group and days 3-5 in sham operation group were mild (HIS<2 scores). The correlation test of BC and HIS was negative( r=-0.880, P<0.001). After the application of anisodamine on dose of 0.2 mg/kg, VI, VV and BC of the young rats on day 3 postcystostomy significantly increased, compared with those before intervention [(643.500±65.889) s, (1.073±0.110) mL, (1.076±0.110) mL vs.(367.938±77.697) s, (0.612±0.129) mL, (0.617±0.129) mL, all P<0.05], while PVR, Pves.max and Pves.thr did not significantly change compared with those before intervention. Conclusion:The recent abnormal changes of urodynamics postcystostomy were related to the traumatic acute bladder inflammation in the young rats.On day 5 after the surgery, the bladder function basically returned to normal with the regression of the acute bladder inflammation.Anisodamine at 0.2 mg/kg dose could effectively relieve the symptoms of overactive bladder postcystostomy.

Objective To identify the risk factors associated with recurrent urinary tract infection (RUTI) in children with neurogenic bladders (NB) who received clean intermittent catheterization (CIC) in order to provide recommendations for reducing the risk of RUTI.Methods Records of 184 children with NB managed by CIC at the Department of Urology Surgery,the First Affiliated Hospital of Zhengzhou University from July 2011 to September 2015 were reviewed and analyzed.According to UTI incidence,they were divided into 2 groups as occasional UTI group (0-1 time/year,OUTI group) and RUTI group (＞ 1 time/year).The clinical and urodynamic data were compared between 2 groups,and the risk factors were identified by regression analysis.Results Of the total patients,147 patients (79.9％) were diagnosed as OUTI and 37 cases (20.1％) as RUTI.Median follow-up lasted for average 27 months (12-39 months).The characteristics of RUTI group was indicated significantly in the study,which included increasing age(7.4 years old vs.5.9 years old),a higher level of spinal lesions,and more vesicoureteral reflux(VUR),and there were significant differences in bladder wall thickness(4.7 cm vs.3.6 cm) and lower bladder compliance compared with RUTI group (all P ＜ 0.05).But there was no statistical significance in gender,antibiotics,hydronephrosis,incontinence,bladder capacity,detrusor overactivity,detrusor sphincter dyssynergia and detrusor leakage point pressure between 2 groups (all P ＞ 0.05).Increasing age,increased bladder wall thickness,lower bladder com-pliance and the presence of VUR were independent risk factors associated with RUTI group (all P ＜ 0.05).Conclusions Increasing age,increasing bladder wall thickness,lower bladder compliance and VUR are the risk factors for RUTI in NB children managed with CIC.It is necessary to follow up video-urodynamic and ultrasound findings in order to identify the high-risk patients and provide the evidence for preventing RUTI.
