Objective To discuss the clinical efficacy and safety of bilateral internal iliac artery Fogarty balloon occlusion in uterine curettage for patients with cesarean scar pregnancy(CSP).Methods The clinical data of a total of 80 CSP patients,who were admitted to the Fuyang People's Hospital of China between January 2021 and September 2022 to receive treatment,were retrospectively analyzed.The patients were divided into the observation group(n=40)and the control group(n=40).For the patients of the observation group,the hysteroscopic uterine curettage was carried out under the situation of bilateral internal iliac artery Fogarty balloon occlusion and during the operation the internal iliac artery was intermittently blocked.The embryo was removed,and the hemostasis was accomplished by electrocoagulation or surgical suture.For the patients of the control group,the hysteroscopic uterine curettage was performed within 1-2 days after uterine artery embolization(UAE).The digital subtraction angiography(DSA)fluoroscopy time,body surface radiation dose,blood loss during uterine curettage,time spent for uterine curettage,length of hospital stay,and postoperative follow-up results were compared between the two groups.Results Successful uterine curettage was accomplished and the uterus was retained in all the patients.In the observation group,no balloon-related complications occurred.In the control group,all the 40 patients developed different degrees of fever,pain at uterine area,and other post-embolization symptoms after UAE.In the observation group and the control group,the DSA fluoroscopy time was(9.2±1.1)seconds and(1 273.6±141.1)seconds respectively,the body surface radiation dose was(7.7±0.8)mGy and(1 503.8±101.8)mGy respectively,the differences between the two groups were statistically significant(both P＜0.05);the blood loss during uterine curettage was(30.3±14.7)mL and(27.5±13.2)mL respectively,the time spent for uterine curettage was(41.6±16.2)min and(42.8±15.0)min respectively,the differences between the two groups were not statistically significant(both P＞0.05);the length of hospital stay was(6.0±0.7)days and(7.3±0.8)days respectively,the difference between the two groups was statistically significant(P＜0.05).All patients were followed up for more than 3 months,the time of β-hCG turning to negative,time of vaginal bleeding,time of menstruation returning to normal,and patient satisfaction rate in the observation group were(21.1±2.4)days,(8.2±1.1)days,(29.5±2.2)days and 95.0%(38/40)respectively,which in the control group were(24.6±3.3)days,(13.6±2.6)days,(46.7±7.3)days and 67.5%(27/40)respectively,the differences in the above indexes between the two groups were statistically significant(all P＜0.05).Conclusion In performing uterine curettage for CSP patients,both bilateral internal iliac artery Fogarty balloon occlusion and UAE can significantly reduce the intraoperative blood loss,but bilateral internal iliac artery Fogarty balloon occlusion is superior to UAE in reducing radiation dose,in shortening the patient's hospital stay,the time of β-hCG turning to negative,the time of vaginal bleeding and the time of menstruation returning to normal,and in improving the patient satisfaction rate.

Objective: To examine the correlation between frailty and lifestyle factors among middle-aged and elderly populations, so as to provide insights into the management of frailty among middle-aged and elderly populations. Methods : Middle-aged and elderly residents at ages of 45 ot 69 years were recruited using the convenient sampling method from seven townships in Changxing County of Zhejiang Province from 2019 to 2020. The demographic characteristics and lifestyle factors were collected using questionnaires, and the frailty was measured using the Chinese version of Tilburg Frailty Indicator ( TFI ). Factors affecting frailty were identified among middle-aged and elderly populations using the multivariable logistic regression model. Results: A total of 7 170 residents were surveyed, including 2 780 males ( 38.77% ) and 4 390 females ( 61.23% ), which had a median age of 56 (interquartile range, 10) years. The median frailty score was 2 (interquartile range, 3 ) among the study subjects, and the median frailty score was 2 ( interquartile range, 2 ) among residents at ages of 45 to 59 years, and 2 (interquartile range, 3) among residents at ages of 60 to 69 years. The overall detection of frailty was 16.07%, and the detection of frailty was 13.52% among subjects at ages of 45 to 59 years and 21.01% among subjects at ages of 60 to 69 years. Multivariable logistic regression analysis identified physical activity ( OR=0.826, 95%CI: 0.719-0.949 ) and sleep quality ( OR: 3.376-11.493, 95%CI: 2.907-15.808 ) as factors affecting frailty among middle-aged and elderly residents. Following age stratification, physical activity ( OR=0.817, 95%CI: 0.681-0.981 ) and sleep quality ( OR: 3.076-11.566, 95%CI: 2.518-18.216 ) as factors affecting frailty among subjects at ages of 45 to 59 years, while sleep quality ( OR: 3.777-11.827, 95%CI: 3.002-18.547 ) significantly correlated with frailty among residents at ages of 60 to 69 years. Conclusion Physical activity and sleep quality are associated with the risk of frailty among middle-aged and elderly populations.

Objective:To investigate the different outcomes of two types of acute kidney injury (AKI) according to standard of Kidney Disease: Improving Global Outcomes-AKI (KDIGO-AKI), and to analyze the risk factors that affect the prognosis of intensive care unit (ICU) patients in China.Methods:A secondary analysis was performed on the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a multicenter prospective study involving 3 063 patients in 22 tertiary ICUs in 19 provinces and autonomous regions of China. The demographic data, scores reflecting severity of illness, laboratory findings, intervention during ICU stay were extracted. All patients were divided into pure AKI (PAKI) and acute on chronic kidney disease (AoCKD). PAKI was defined as meeting the serum creatinine (SCr) standard of KDIGO-AKI (KDIGO-AKI SCr) and the estimated glomerular filtration rate (eGFR) at baseline was ≥ 60 mL·min -1·1.73 m -2, and AoCKD was defined as meeting the KDIGO-AKI SCr standard and baseline eGFR was 15-59 mL·min -1·1.73 m -2. All-cause mortality in ICU within 28 days was the primary outcome, while the length of ICU stay and renal replacement therapy (RRT) were the secondary outcome. The differences in baseline data and outcomes between the two groups were compared. The cumulative survival rate of ICU within 28 days was analyzed by Kaplan-Meier survival curve, and the risk factors of ICU death within 28 days were screened by Cox multivariate analysis. Results:Of the 3 063 patients, 1 042 were enrolled, 345 with AKI, 697 without AKI. The AKI incidence was 33.11%, while ICU mortality within 28 days of AKI patients was 13.91% (48/345). Compared with PAKI patients ( n = 322), AoCKD patients ( n = 23) were older [years old: 74 (59, 77) vs. 58 (41, 72)] and more critical when entering ICU [acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score: 23 (19, 27) vs. 15 (11, 22)], had worse basic renal function [eGFR (mL·min -1·1.73 m -2): 49 (38, 54) vs. 115 (94, 136)], more basic complications [Charlson comorbidity index (CCI): 3 (2, 4) vs. 0 (0, 1)] and higher SCr during ICU stay [peak SCr for diagnosis of AKI (μmol/L): 412 (280, 515) vs. 176 (124, 340), all P < 0.01]. The mortality and RRT incidence within 28 days in ICU of AoCKD patients were significantly higher than those of PAKI patients [39.13% (9/23) vs. 12.11% (39/322), 26.09% (6/23) vs. 4.04% (13/322), both P < 0.01], while no significant difference was found in the length of ICU stay. Kaplan-Meier survival curve analysis showed that the 28-day cumulative survival rate in ICU in AoCKD patients was significantly lower than PAKI patients (Log-Rank: χ2 = 5.939, P = 0.015). Multivariate Cox regression analysis showed that admission to ICU due to respiratory failure [hazard ratio ( HR) = 4.458, 95% confidence interval (95% CI) was 1.141-17.413, P = 0.032], vasoactive agents treatment in ICU ( HR = 5.181, 95% CI was 2.033-13.199, P = 0.001), and AoCKD ( HR = 5.377, 95% CI was 1.303-22.186, P = 0.020) were independent risk factors for ICU death within 28 days. Conclusion:Further detailed classification (PAKI, AoCKD) based on KDIGO-AKI SCr standard combined with eGFR is related to ICU mortality in critical patients within 28 days.

Objective: To discuss the affect of glycosylated hemoglobin (HbA1c) level for the onset of nonalcoholic fatty liver disease (NAFLD) in cohort population. Methods: An epidemiological survey of the relationship between HbA1c and NAFLD conducted in 2012 was based at cohort baseline, and three follow-up sessions conducted in 2013, 2014 and 2015. In total 2 811 subjects were included in the study after exclusion of NAFLD patients at baseline and those who lost their lives due to relocation, and death. The Cox proportional hazard model was used to analyze the relationship between glycosylated hemoglobin and other risk factors of NAFLD. Continuous variables were compared using the t-test or the Mann-Whitney test. χ ²-test was used for the measurement of categorical data. Results: A total of 2 811 subjects with mean age of 59 (58.2±9.8) years old, including 1 664 males and 1 147 females. Age, waist circumference, body mass index, systolic blood pressure, γ-glutamyltransferase and fasting blood glucose level of HbA1c abnormal group were higher than normal group. The incidence of NAFLD in the abnormal HbA1c level group (25.4%) was higher than normal group (14.9 %), and diastolic blood pressure, high-density lipoprotein cholesterol was lower than normal group and the differences were statistically significant. During the three follow-up intervals, there were 440 new cases of NAFLD, consisting 285 males and 155 females with cumulative incidence of 15.7% (440/2 811). Multivariate Cox regression analysis showed that patients with elevated HbA1c had a higher risk of developing NAFLD (HR 1.796; 95% CI 1.335~2.418; P < 0.01), and the increased HbA1c level after adjustment for gender, age, and metabolic syndrome-related factors remained an independent risk factors for NAFLD (HR 1.580; 95.0% CI 1.161-2.152; P < 0.01). Conclusion An elevated HbA1c levels have a positive predictive value for the onset of NAFLD.

Objective To observe the effect of yin-tonifying and fire-removing prescription on IL-10 and IL-18 in systemic lupus erythematosus patients with syndrome of internal heat due to yin deficiency.Methods A total of 86 systemic lupus erythematosus patients with syndrome of internal heat due to yin deficiency were enrolled and randomly divided into control group and research group,43 cases in each group.The control group was treated with conventional western medicine,while research group was treated with yin-tonifying and fire-removing prescription on basis of control group.The TCM symptom score,serum IL-10 and IL-18 levels and the incidence rate of adverse reactions were compared between the two groups.The clinical efficacy of the two groups was evaluated.Results Mter treatment,the levels of IL-10 and IL-18 in both group decreased significantly,and the levels in research group were significantly lower than control group (P ＜ 0.05).The total effective rate was 95.35％ in research group,which was significantly higher than 69.77％ in the control group (P ＜ 0.05).The incidence rate of adverse reactions was 6.98％ in the research group,whichwas similar to 9.30％ in the control group (P ＞ 0.05).Conclusion For systemic lupus erythematosus patients with syndrome of internal heat due to yin deficiency,yin-tonifying and fire-removing prescription can significantly improve the clinical efficacy,alleviate clinical symptoms,and will not increase the incidence rate of adverse reactions.

Objective To study the correlation between non-alcoholic fatty liver disease (NAFLD)and glycosylated hemoglobin (HbA1 c) in middle-aged and aged population.Methods A total of 4 127 inservice workers and retirees aged 45 years old or above from one petrochemical enterprise in Ningbo were enrolled in our study.The waistline,body mass index,blood pressure,fasting blood-glucose,blood lipid profile,glutamyltranspeptidase,HbA1c and epigastrium B ultrasound were investigated.According to the quartile of HbA1c level,participants were divided into four groups,namely,Q1 group ≤5.2％,Q2 group ＞ 5.2％-5.4％,Q3 ＞ 5.4％-5.6％ and Q4 group ＞ 5.6％.The prevalence of NAFLD and clinical characteristics of each group were analyzed.Logistic regression was used to predict independent risk factors of NAFLD.Results The morbidity of NAFLD was 27.2％ with 31.9％ in male and 21％ in female,which was significantly higher in men.In Q1,Q2,Q3 and Q4 group,the prevalence of NAFLD were 18.5％ (178/961),22.8％ (185/812),25.6％ (280/1 095),38.1％ (480/1 259) respectively.With the increase of HbA1 c level,the morbidity of NAFLD increased synchronously.The age,systolic pressure,total cholesterol,low densitylipoprotein cholesterin and fasting blood-glucose were all elevated according to the increase of HbA1 c in 1 123 NAFLD patients.Multi-factor logistic regression analysis indicated that high HbAlc level was the risk factor of NAFLD (OR =1.67,95％ CI 1.15-2.43,P =0.007).Conclusion HbA1c is an independent risk factor of NAFLD and both of these are closely related to blood lipid metabolism disorder.

Objective To explore the relationship between thyroid hormone and colorectal adenomatous polyps (CAP) in middle-aged and elderly people.Methods We surveyed 3 042 middle-aged employees and retirees aged 45 years and over at a petrochemical enterprise of Ningbo.Their colonoscopic findings,body mass index,waist circumference and thyroid function were analyzed.Results Age and serum free triiodothyronine (FT3) of females with CAP were higher than those of the corresponding non-CAP group,so were age and waist circumference of males with CAP (P ＜ 0.05).Furthermore,these differences were statistically significant.The detection rate of CAP was significantly higher in males than in females (x2 =49.418,P ＜ 0.01).The detection rate of CAP was higher in females with higher levels of FT3.Multivariate unconditional logistic regression analyses showed the effects of thyroid hormone on the CAP differed by gender.Age and FT3 (OR =1.60,95％ CI:1.12-2.28,P =0.01) were correlated with CAP in females.However,only age and waist circumference were correlated with CAP in males.Conclusion Elevated FT3 may be a risk factor of CAP in elderly females.The detection rate of CAP may not be affected by FT3 levels in males.

Objective To explore the value of diffusion weighted imaging (DWI)as a quantitative analysis tool for chronic cervical spondylotic myelopathy (CSM)with 3.0T MRI.Methods Cervical routine MR T2-weighted imaging(T2 WI)and diffusion weighted imaging were performed in 38 patients with cervical spondylotic myelopathy (CSM group)and 20 healthy volunteers (control group),and sagittal image of apparent diffusion coefficient (ADC)was reconstructed.The number of high T2 signal of the spinal cord were calculated in both healthy volunteers and CSM patients.The ADC values of CSM groups were measured in C3,T1 -C2 level and the compression or abnormal signal parts of the spinal cord;the control group measured C3、C4-C6 and T1 -T2 level in the spinal cord.Results There were 3 cases,1 case,6 cases and 8 cases high T2 signals in CSM patients from Ⅰ to Ⅳ levels,while there were 2 cases show high T2 signals in control group,respectively.The mean ADC values of the compression part were gradual-ly increased in CSM group from Ⅰ to Ⅳ level.There were significant differences of the mean ADC values of compression part be-tween the control group,CSMⅠ-Ⅱ level and the CSM Ⅳ level.Conclusion From our study,the change of ADC value of spine cord occured earlier than the change of signal in CSM patients.Therefore,the ADC value of spine cord might reflect the degree of spinal cord compression from CSM patients.

Objective To observe any therapeutic effect of laser irradiation on pathological inflammatory reactions in ulcerative colitis (UC) induced by oxazolone,and to investigate possible mechanisms.Methods Six rats were selected as a normal control group.Another 24 rats with UC induced by oxazolone were randomly assigned to a UC model group (n =8),a 400 mW laser group (161.3 mW/cm2,n =8),and a 200 mW laser group (80.6 mW/cm2,n =8).All the rats were fixed in custom-built devices.Those in the therapy groups were treated daily,10 min per time,for 10 days.After the end of the last irradiation session,disease activity indexes (DAIs)were observed.Rats from every group were sacrificed 24 h after the last irradiation in order to observe any pathological changes in colon tissue,the weight of fresh ulcerated tissues,and gross changes in morphology.Colon segments were stained with hematoxylin-eosin and histological lesion scoring was performed under a light microscope.Any changes in inflammatory edema in the colonic mucous membrane were observed before and after laser irradiation.Results The UC model was successfully established.Average body weight in the 400 mW laser group increased significantly more than in the UC model group,approaching that of the normal control group.DAI decreased significantly.The thickness of the epithelial mucous membrane,lamina propria and submucosa was basically restored.Histological lesion scores also improved significantly,and the weight of fresh ulcerative tissue was significantly lower.Mucous membrane ulcers,submucosa edema and inflammatory cell infiltration all were alleviated significantly,merely presenting a few inflamed cells and small amounts of periphlebitis.In the 200 mW laser group all these outcome measures improved significantly compared with the UC model group,but were not as good as in the 400 mW laser group,and the rats needed longer to recover.Conclusion Laser irradiation at 400 mW has advantages over 200 mW,and could significantly relieve the pathological inflammatory response in colonic tissue,decrease submucosa edema and ameliorate other symptoms of ulcerative colitis,at least in rats.
