Objective:To investigate the prevalence and influencing factors of frailty among older adults diagnosed with non-ST-segment elevation acute coronary syndrome(NSTE-ACS).Methods:We conducted a cross-sectional study involving patients aged 65 years and older with NSTE-ACS, who were admitted to the Cardiology Center and the Department of Geriatrics at Beijing Friendship Hospital, Capital Medical University, between January 2020 and November 2021.Patients were categorized into non-frail, pre-frail, and frail groups based on the FRAIL scale.We collected clinical data, including general health conditions, comorbidities, laboratory results, treatments, and comprehensive geriatric assessments.Logistic regression analysis was employed to identify the influencing factors associated with frailty and pre-frailty in older adults with NSTE-ACS.Results:A total of 528 patients with NSTE-ACS were included in the study, comprising 308 males(58.3%)and 220 females(41.7%). The age range of participants was from 65 to 90 years, with a median age of 72(68, 76)years.The prevalence of frailty among older adults with NSTE-ACS was 11.4%(60/528), while pre-frailty was observed in 51.9%(274/528), and non-frailty in 36.7%(194/528). Compared to the non-frail and pre-frail groups, patients in the frail group were older, had a higher proportion of females, exhibited a greater prevalence of chronic diseases, and presented with elevated inflammatory markers.Additionally, frail patients demonstrated poorer nutritional status and reduced functional ability(all P<0.005). Risk factors for frailty in older adults with NSTE-ACS included older age( OR=1.110, 95% CI: 1.032-1.194, P=0.005), diabetes( OR=2.489, 95% CI: 1.091-5.679, P=0.030), cerebrovascular disease ( OR=4.151, 95% CI: 1.660-10.384, P=0.002), chronic kidney disease ( OR=42.874, 95% CI: 3.957-464.513, P=0.002), and elevated white blood cell levels( OR=1.424, 95% CI: 1.125-1.802, P=0.003). Conversely, being male( OR=0.252, 95% CI: 0.105-0.604, P=0.002)was identified as a protective factor against frailty in this patient population.For pre-frail older adults with NSTE-ACS, identified risk factors included diabetes( OR=1.882, 95% CI: 1.199-2.955, P=0.006), cerebrovascular disease( OR=1.938, 95% CI: 1.176-3.195, P=0.009), and chronic kidney disease ( OR=12.137, 95% CI: 1.536-95.934, P=0.018). Similarly, being male( OR=0.601, 95% CI: 0.376-0.961, P=0.033)was also a protective factor for pre-frailty in older adults with NSTE-ACS. Conclusions:The prevalence of frailty and pre-frailty among older adults with NSTE-ACS is notably high.Common risk factors for frailty and pre-frailty in this population include female gender, diabetes, cerebrovascular disease, and chronic kidney disease.

In modern society,the diversity of risk causes,the complexity of risk trans-mission paths and the cascading effect of risk consequences make the uncertainty of the run risk of medical and health system increase sharply,and risk governance has become a rising topic in the academic circle.However,the traditional risk management system is riddled with difficulties,which has been difficult to meet the needs of modern governance,and resilient governance provides a new perspective for improving the governance capacity of the medical and health system run risk,and promotes risk management to"turn brittle into tough".How to empower the technical advantages of resilience governance to manage the run risk of the healthcare system,break the obstruction of the traditional governance mechanism,and explore its internal mechanism and driving mechanism are the key issues to realize the innovation of resilient governance and the modernization of governance capacity.

Objective:To investigate the risk factors for organoid culture failure in colorectal cancer.Methods:This was a retrospective observational study. Tumor specimens were obtained from 1130 patients with colorectal cancer who had undergone surgery or biopsy and had no other concurrent malignancies at Nanfang Hospital of Southern Medical University from December 2021 to November 2022. Organoid culture was performed on 1231 tumor tissue samples. Univariate analysis and multivariate logistic regression were used to analyze the factors that might have influenced the rate of successful organoid culture of colorectal cancer tissue samples.Results:The median (range) duration of organoid culture was 7 (3–12) days. The overall rate of successful culture was 76.3% (939/1231). The rate of successful organoid cultures varied according to the sampling site, malignant ascites having the highest success rate (96.4%, 27/28), followed by liver metastases (83.1%, 54/65), lung metastases (8/10), primary tumors (76.0%, 816/1074), omental metastases (10/14), peritoneal metastases (61.5%, 16/26), ovarian metastases (3/5), and lymph node metastases (5/9). The difference in rates of successful organoid culture between primary tumors and malignant ascites was statistically significant ( P=0.012), whereas none of the other rates of successful organoid culture success differed significantly (all P>0.05). The rate of successful organoid culture was 96.4% (27/28) for malignant ascites obtained by abdominal puncture, 76.5% (864/1130) for surgical specimens, and 65.8% (48/73) for endoscopic biopsies; these differences are statistically significant (χ 2=10.773, P=0.005). The rate of successful organoid culture was 62.5% (40/64) in the neoadjuvant chemoradiotherapy group, which is significantly lower than in the non-adjuvant (76.9%, 787/1023) and chemotherapy groups (77.8%, 112/144) (χ 2=7.134, P=0.028). Multivariate logistic regression analysis revealed that endoscopic biopsy (OR=0.557, 95%CI: 0.335–0.924, P=0.024) and neoadjuvant chemoradiotherapy (OR=0.483, 95%CI: 0.285–0.820, P=0.007) were independent risk factors for failure of organoid culture of colorectal cancer samples. Malignant ascites (OR=8.537, 95%CI:1.154–63.131, P=0.036) and abdominal puncture (OR=8.294, 95% CI: 1.112–61.882, P=0.039) were identified as independent protective factors. Conclusions:The rate of successful organoid culture was influenced by the sampling site, sampling method, and chemoradiotherapy. The rate of successful organoid culture was lower for endoscopic biopsies and in patients receiving preoperative neoadjuvant chemoradiotherapy, and higher for malignant ascites. We consider that culture of malignant ascites is preferable when peritoneal metastases are suspected.

Objective: To investigate the echocardiographic characteristics, pathological anatomy and genetic abnormality of congenital absent semilunar valves in first trimester. Methods: Eleven cases of congenital absent semilunar valve fetus diagnosed at 11-13^{+ 6} weeks of gestation in Guangxi Magernity & Child Healthcare Hospital from December 2014 to December 2018 were analyzed. The characteristics of echocardiography and the abnormal microanatomy of cardiac tissue after labor induction was compared. Results: The crown-lump length of the 11 fetus was 46-74(62.0±9.2)mm, and nuchal translucency thickness(NT) was 2.4-10.4 (6.4±2.6)mm. The NT of 10 cases were greater than 3.0 mm. Color Doppler flow imaging revealed that biphasic bidirectional flow in the aortic arch and/or pulmonary artery at the 3VT view( "to-and-fro" ) in those 11 cases, and pansystolic turbulence and pandiastolic reflux spectrum were showed on spectral Doppler. Among them, there were 10 cases of " stealing type" , including 2 cases of isolate absent aortic valves, 3 cases of absent pulmonary valves and 5 cases of absent both aortic and pulmonary valves; and all the 10 cases had secondary ultrasonic manifestations of fetal heart failure. Chromosome analysis and detection of genes showed that 4 cases with Trisomy 13 syndrome, 3 cases with Trisomy 18 syndrome, 1 case with 22q11.2 deletion, 1 case with 12q24.32q24.33 deletion and 1 case was normal. Pathological anatomy revealed enlarged heart in 8 cases, isolate absent aortic valves in 2 cases (1 case complicated with pulmonary atresia, absence of ductus arteriosus and thymus), absent pulmonary valves in 3 cases, absent both aortic and pulmonary valves in 3 cases, relics of semilunar valves in 3 cases. And 2 cases of absent pulmonary valves and 3 cases of absent both aortic and pulmonary valves with short and thick ductus arteriosus. Only 1 case was congenital absent semilunar valve in " non-stealing type" without secondary ultrasonic manifestations of fetal heart failure. Chromosome analysis and detection of genes showed 22q11.2 deletion, and there were relics of semilunar valves in the pathological anatomy. It also combined with tetralogy of Fallot and absence of ductus arteriosus. Conclusions In first trimester, congenital absent semilunar valves are more common as " stealing type" . The echocardiographic features of congenital absent semilunar valves are the " in-out sign" of aorta arch and/or pulmonary artery and biphasic spectrum in spectral Doppler. Trisomy 13 syndrome and trisomy 18 syndrome significantly increased the risk of congenital absent semilunar valves in " stealing type" in first trimester.

Objective To study compatibility rule of herb-pair in rhubarb after compatibilities with fructus aurantii Immaturus,Chinese goldthread rhizome,moutan cortex,peach seed and kansui radix stir-baked with vinegar, and to observe its anti-inflammation and acute toxicity. Methods Mice were gavaged by 15,30 g?kg-1 rhubarb and rhubarb, rhubarb frutus aurantii immaturus rhizoma coptidis, radix et rhizoma rhei peony, rhubarb, semen persicae and rhubarb extracts from euphorbia kansui, respectively, in the morning and evening once, for 7 d.The effects of five different compatibility of Rhubarb on acute inflammation were observed in the mouse paw swelling induced by carrageenan. The classical method were used to determine acute toxicity of rhubarb and the contents of five different compatibility of rhubarb. Results Compared with the control group, the contents of five different compatibility of rhubarb with high and low dosage groups(30,15 g?kg-1 ) could inhibit the paw edema in mice,reduce NO and MDA production and enhanced activity of SOD in mice inflammatory tissue. The LD50 was not determined. Calculated by crude drug content, the MLD of rhubarb compatibilities with fructus aurantii immaturus, Chinese goldthread rhizome,moutan cortex,peach seed and kansui radix stir-baked with vinegar were 145.33,142.30,117.53,103.45, 113.09,182.36 g?kg-1 respectively, which were respectively equal to 581,569,470,418,452 ,729 times of people, s daily dried medicinal herb dosage. Conclusion The five different herb-pair have anti-inflammation effects after compatibility of Rhubarb, and it got best effects when rhubarb compatibility with kansui radix stir-baked, the next were rhubarb compatibility with Chinese goldthread rhizome and moutan cortex. It was basic security and low toxicity of herb-pair in rhubarb after compatibilities.

OBJECTIVETo study and summarize the etiology of children patients with chronic kidney disease (CKD) stage 2 to 5 seen in Children's Hospital of Fudan University from Jan. 2004 to Dec. 2013.

METHODBy complying with the NKF-K/DOQI guidelines, we collected data of 264 cases of children patients with CKD stage 2-5 from Jan. 2004 to Dec. 2013 in the medical record system of Children's Hospital of Fudan University. And we retrospectively analyzed their age and CKD stage at first diagnosis, primary diseases, complications, etc.

RESULTIn the collected 264 cases, 52 cases (19.7%) were diagnosed at stage 2, 67 (25.4%) at stage 3, 52 (19.7%) at stage 4 and 93 (35.2%) at stage 5. For disease causes, 116 cases (43.9%) had congenital anomalies of the kidney and urinary tract (CAKUT), 61 cases (23.1%) had glomerular disease, 15 (5.7%) had hereditary kidney disease, 14 (5.3%) had other diseases and in 58 cases (22.0%) the causes of disease were unknown. In the group with age between 0 and 3.0 and 3.1 and 6.0 years, 57.1% (24 cases) and 60.0% (30 cases) had primary disease with CAKUT. In the group with age older than 10 years, 49.2% (30 cases) had primary disease with glomerular disease and 32.0% (32 cases) with unknown causes.

CONCLUSIONThe major cause of CKD stage 2-5 in children in our hospital during the last ten years was CAKUT (43.9%), followed by glomerular disease (23.1%). The primary diseases of CKD were significantly different between the 2 age groups. CAKUT was more common in infants and preschool children while for adolescents, glomerular disease was the major cause.

Objective To compare the clinical results of the ureteral reimplantation with the traditional open approach and laparcocopic pneumovesical approach. Methods A retrospective review of 108 patients who underwent ureteral reimplantation from December 2004 to October 2010 was conducted.The patients were divided into open and pneumovesical groups according to the surgical approach.Perioperative results were compared between the two groups in terms of operative time,postoperative intravenous antibiotics duration,catheterization duration,postoperative stay,average total cost and surgical cost,respectively.And the pneumovesical group was divided into two stages by time,compared the operative time of the two stages and between the later stage and the open group. Results The postoperative hospital stay of pneumovesical group was shorter than the open group (6.8 ± 1.9 d and 8.9 ± 2.9 d,P =0.002 ).For catheterization duration,the pneumovesical group was shorter than the open group as well (5.2 ± 1.2 d and 6.2 ±2.2 d,P=0.057).For the postoperative intravenous antibiotics duration,the pneumovesical group was 5.0 ± 1.3 h,the open group was 5.4 ±1.6 h (P =0.159).For the total cost,the pneumovesical group was 16 067.9 ±4 295.8 RMB,the open group was 15 617.7 ± 5 486.5 R MB (P =0.168).For the surgical cost,the pneumovesical group was 9369.4 ± 1366.6 RMB,the open group was 7397.9 ± 1797.3 RMB ( P =0.083 ).Operative duration of the pneumovesical group and open group were 3.2 ± 1.1 h and 2.3 ± 1.1 h ( P =0.003).For pneumovesical group,the mean operative durations of the two stages were 3.6 h and 2.8 h (P =0.286).And the later stage of pneumovesical group was a little longer than the open group,but no significant difference ( P =0.234 ).No major complication was found in the 2 groups during the operative time and the postoperative hospital stay.Twenty-four patients (38 ureters) of the pneumovesical group were followed up with micturating cystourethrography ( MCU),ureterovesical reflux recurred in 3 patients.Two patients changed from grade Ⅲ to grade Ⅰ and 1 patient changed from grade Ⅴ to grade Ⅲ after the surgery.Five patients (9 ureters) of the open group were followed up,1 patient found bladder diverticulum; 1 patient found ureteral stricture 6 months after the surgery and got improved after secondary ureteral relimplantation surgery. Conclusions The pneumovesical approach is shorter than the open group in postoperative hospital stay and catheterization reserved duration.The pneumovesical approach is a safe and effective option for ureteral reimplantation.
