ABSTRACT

OBJECTIVE To study the triterpenoid saponins from Anemone rivularis var. flore-minore and their antitumor activities. METHODS The n-butanol extract of 70% ethanol extract from rhizome of the plant was separated. The triterpenoid saponins were separated and purified by normal silica gel column chromatography ,reversed phase ODS column chromatography , Sephadex LH- 20 gel column chromatography and semi-preparation high performance liquid chromatography. The structures of these saponins were identified by spectral analysis (NMR and MS )and physical and chemical properties. MTT assay was used to test the proliferation inhibitory activity of the compounds against five kinds of human tumor cells (HL-60 cells,A549 cells,HepG2 cells,HeLa cells and U 87MG cells ). The apoptosis inducing effect of compound 7 on U 87MG cells was evaluated by flow cytometric Annexin V-FITC/PI staining test. RESULTS:Sixteen triterpenoid saponins were obtained and identified as 3 β-O-β-D-xylopyranosyl-(1→2)-α-L-arabinopyranosyl-oleanolic acid-28-O-α-L-rhamnopyranosyl- (1→4) -β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside(1),3β-O-L-arabinopyranosyl oleanolic acid- 28-O-β-D-glucopyranoside(2),saponin B (3), 163.com oleanolic acid- 3β-O-β-D-glucopyranosyl-(1→2)-α-L-arabino- pyranoside(4),HN-saponin F (5),clematoside S (6),prosapogenin CP 4(7),cussonside B (8),pulsatilla saponin C (9), clemastanoside D (10),3 β-O-β-D-glucopyranosyl-(1→2)-β-L-arabinopyranosyl-hederagenin-28-O-β-D-glucopyranoside(11), ciwujianoside C 3(12),ciwujianoside A 1(13),huzhangoside D (14),kalopanaxsaponin B (15)and hederacolchiside E (16). Compounds 3,4,6-9 displayed inhibitory activities on the proliferation of tumor cells to different extent ,and compound 7 had the strongest activity ;compound 7 induced the apoptosis of U 87MG cell so as to inhibit the proliferation of cancer cells in a time-dependent manner. CONCLUSIONS The obtained 16 saponins are all identified as oleanolane-type ,among which compound 1 is a new compound. The monodesmosidic saponins ,the sugar chain of which attached at C- 3 and a free carboxyl at C- 28, possess stronger antitumor activity than others.

ABSTRACT

Objective:To explore the influence of elastic band aerobics training on cardiovascular risk factors in adults.Methods:Twenty-four health management centers participated in the competition. Each individual participant learned elastic band aerobics through video and tested their own indexes before and after intervention. Height, body weight (BW), muscle content (MC), fat content (FC), waist circumference (WC), hip circumference (HC), body fat rate (BFR), resting systolic and diastolic blood pressure (SBP and DBP) were measured. A paired samples t-test was used to analyze pre-and post-test results.Results:After 8 weeks of elastic band aerobics training, there were significant differences in body weight, body mass index (BMI), waist circumference, body fat content, systolic and diastolic blood pressure for male contestants before and after training ( P<0.01). These decreased by 1.39%, 1.45%, 0.98%, 3.61%, 2.28%, 2.34%, and 3.05% respectively. Weight, waist circumference, hip circumference, waist hip ratio, body fat content and rate of female contestants decreased by 1.25%, 1.59%, 0.65%, 0.99%, 4.22%, and 2.38% respectively ( P<0.01). There were significant differences in absenteeism between the top 10 and bottom 14 teams ( P<0.05). Average absenteeism rates were 2.8% and 10.7% respectively. Overall attendance rate of participants was 92.6%, higher than the clinical standard of an 80% level of compliance. Conclusions:Eight-week elastic band aerobics training can significantly improve body composition of adults, reducing body fat rate and waist circumference. Using competition as an opportunity to exercise promotes implementation and persistence of sports training programs.

ABSTRACT

Objective:To investigate the predictive value of fasting blood glucose on clinical outcome after intravenous thrombolysis in patients with severe acute ischemic stroke (AIS).Methods:From January 2016 to November 2020, consecutive patients with severe AIS receiving intravenous thrombolysis in the Department of Neurology, Shengli Oilfield Central Hospital were enrolled retrospectively. Severe AIS was defined as the baseline National Institutes of Health Stroke Scale (NIHSS) score ≥15. The primary endpoint was the clinical outcome evaluated according to the modified Rankin Scale at 90 d after onset. 0-2 was defined as a good outcome and a score of >2 were defined as a poor outcome. The secondary endpoint events were any intracranial hemorrhage and symptomatic intracranial hemorrhage (sICH). Intracranial hemorrhage was defined as any local or distant parenchymal hemorrhage shown by craniocerebral imaging during the hospitalization. sICH was defined as any intracranial hemorrhage and the NIHSS score increased by ≥4 within 7 d after treatment. Univariate and multivariate logistic regression analysis were used to determine the independent influencing factors of various endpoint events. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of fasting blood glucose levels for endpoint events. Results:A total of 113 patients with severe AIS treated with intravenous thrombolysis were included, and 73 (64.6%) had a poor outcome; 29 (25.7%) had intracranial hemorrhage, of which 10 (8.8%) were sICH. Multivariate analysis showed that fasting blood glucose was the independent risk factors for poor outcome (odds ratio [ OR] 1.451, 95% confidence interval [ CI] 1.053-2.000; P=0.023) and sICH ( OR 1.235, 95% CI 1.013-1.504; P=0.036). The ROC curve analysis showed that the area under the curve of fasting blood glucose predicting poor clinical outcome at 90 d after onset was 0.731 (95% CI 0.637-0.824), the optimal cut-off value was 6.25 mmol/L, and the corresponding sensitivity and specificity were 63.0% and 82.5% respectively. The area under the curve of fasting blood glucose predicting sICH was 0.728 (95% CI 0.577-0.878), the optimal cut-off value was 7.98 mmol/L, and the corresponding sensitivity and specificity were 70.0% and 77.7% respectively. Conclusion:Fasting blood glucose is an independent predictor of sICH and poor outcome at 90 d after onset in patients with severe AIS receiving intravenous thrombolysis.

ABSTRACT

Onset with fever and back pain, an 81-year-old man had sudden oliguria and progressively elevated serum creatine from normal range to 660 μmol/L within 1 week after receiving contrast agents, various antibiotics, and several nonsteroidal anti-inflammation drugs. Urine output recovered after supportive treatment. However, his serum creatinine level rose again soon after a temporary decline accompanied by gross hematuria with almost normal morphology, nephrotic proteinuria, and hypoalbuminemia. Renal biopsy revealed necrotizing glomerulonephritis. Methylprednisolone was intravenously administrated 500 mg per day for 3 days, followed by oral glucocorticoids and cyclophosphamide. Gradually the patient′s serum creatinine descended to 144 μmol/L.

ABSTRACT

A 65-year-old woman presented with intermittent right hand numbness and elevated serum creatinine for more than 2 months. The histological examination of kidney biopsy showed renal arterioles occlusion and interstitial fibrosis. Pathological abnormality was originally considered as a part of systemic atherosclerosis. Thus, rosuvastatin 20 mg/d, fosinopril 10 mg/d, metoprolol 47.5 mg/d and aspirin 0.1g/d were administrated. No improvement of renal function was seen. Further Congo red staining was applied. Diffuse amorphous eosinophilic substance was deposited in interlobular artery and small arteriolar artery. Combined with the abnormal free light chain (FLC) level and ratio (serum κ 340 mg/L, κ/λ 10.932), the diagnosis of systematic light-chain amyloidosis was confirmed. The patient received 3 courses of chemotherapy regimen as BCD (bortezomib 2 mg d1, 8, 15, 22, cyclophosphamide 0.3 g d1, 8, 15, 22 and dexamethasone 40 mg d1, 8, 15, 22). A hematologic partial response was achieved and serum creatinine decreased to 180 μmol/L.

ABSTRACT

Objective:To evaluate whether dialysis modality will affect cognitive function in dialysis population.Methods:This was a cross-sectional study. Chronic dialysis patients in our center was screened from July 2013 to July 2014. All of the subjects received brain magnetic resonance imaging (MRI) examination and comprehensive cognitive function evaluation.Results:A total of 189 chronic dialysis patients were enrolled in this study, 122 cases on hemodialysis (HD) and 67 cases on peritoneal dialysis (PD). There was no significant difference in age between HD and PD groups [(56.4±13.2) years vs (56.4±16.1) years, t=0.004, P=0.997]. The dialysis vintage and serum albumin of HD patients was higher than those of PD patients[58.0(16.8, 107.5) months vs 31.0(7.0, 67.0) months, Z=-3.490, P<0.001; (39.6±3.9) g/L vs (35.3±3.8) g/L, t=7.328, P<0.001, respectively]. The prevalence of cerebral small vessel diseases (CSVDs) was comparable between HD and PD groups (all P>0.05). Compared with HD patients, PD patients presented a 11.90-fold risk of immediate memory impairment (95% CI 1.40-101.08, P=0.023) and a 6.18-fold risk of long-delayed memory impairment (95% CI 2.12-18.05, P=0.001). After adjusting for age, educational lever, dialysis vintage, serum creatinine, and CSVDs, the influence of dialysis modality on memory still worked. PD patients presented a 43% risk of executive function impairment of HD patients ( OR=0.43, 95% CI 0.17-1.04, P=0.061). Conclusions:HD patients manifested better memory than PD patients, while PD probably performed better in executive function than HD patients. There was no significant difference in language function between the two groups. The difference in cognitive function may not be related to CSVDs.

ABSTRACT

Objective:To explore the association between urinary stone disease (USD) and peripheral arterial disease (PAD).Methods:The study was based on the cross-sectional chronic diseases survey performed in Pinggu district, Beijing from March to May, 2014. All subjects completed a questionnaire, physical examination, renal ultrasound examination to detect USD, ankle-brachial index (ABI) examination to detect PAD (defined as ABI<0.9 on either side of the body), and brachial-ankle pulse wave velocity (baPWV) measurement to estimate arterial stiffness. Blood and first morning urine sample were detected for serum creatinine, blood glucose and so on.Results:There were 10 281 participants included in this study. Among these participants, the prevalences of USD and PAD were 5.66% and 3.95%, respectively. Compared with non-stone participants, the persistent USD formers had a higher prevalence of PAD (8.26% vs 3.90%, P<0.001) and baPWV [(16.3±3.5) m/s vs (15.5±3.2) m/s, P<0.001]. Even after adjusting the confounding factors, the persistent USD formers also had a 2.066-fold increased risk of PAD ( OR=2.066, 95% CI 1.276-3.343, P=0.003). In the subgroup analysis, persistent USD patients in older participants who were≥60 years old, women, chronic kidney disease, and central obesity had a significantly increased risk of PAD. Conclusions:In the present population, persistent USD is positively associated with a high risk of PAD and increased arterial stiffness. Patients with persistent USD should be screened for vascular diseases.

ABSTRACT

A 66-year-old male presented with edema for 10 months and high fever for half a month. The patient was diagnosed with type 2 diabetes for 10 years. Renal biopsy revealed membrane nephropathy combined with diabetic nephropathy. A combination regimen with rituximab (1 g, day 1 and day 20), cyclophosphamide (100 mg/d) and prednisone (60 mg/d) was initiated. The dose of prednisone was gradually reduced to 17.5 mg/d within 1.5 months after partial remission of nephrotic syndrome. However, the patient was re-admitted due to high fever, productive cough and mild hand tremor. The lung imaging suggested the diagnosis of community-acquired pneumonia. Ertapenem (1 g/d) was empirically administrated and adjusted to moxifloxacin (0.4 g/d) plus ceftazidime (2 g, 2 times/d) for two weeks. The patient responded and temperature came back to normal. But the fever relapsed after the withdrawal of antibiotics. Mixed infections were suspected, but blood and sputum samples were negative for pathogens. Antibiotics were not effective. The patient recalled a history of pigeon exposure. Positive cryptococcus antigen in blood culture and cerebrospinal fluid unmasked the diagnosis of pulmonary cryptococcosis and cryptococcal meningitis. Fluconazole (200 mg, 2 times/d) and oral flucytosine (1 g, 3 times/d) were given and effective.

ABSTRACT

A 43-year-old male presented with elevated serum creatinine for 4 years and developed abdominal pain for 3 days. He started peritoneal dialysis 2 months ago. Dialysis-related peritonitis was ruled out and acute gastroenteritis was diagnosed. The patient was administrated with ertapenem 500 mg/d. An acute mental abnormality developed 3 days later. After excluded organic encephalopathy, ertapenem was discontinued for the suspicion of antibiotic-related encephalopathy. The frequency of peritoneal dialysis was increased to accelerate the clearance of antibiotics. However, the metal abnormality became even more severe. Then a diagnosis of Wernick-Korsakoff syndrome was considered. After the administration of high dose vitamin B 1, the mental disorder dramatically relieved. Vitamin B 1 30 mg/d is maintained during peritoneal dialysis and the mental disorder does not relapse.

ABSTRACT

Objective:To investigate the current management of nosocomial infection at medical institutions of all levels in Changzhou, so as to provide basis for standardizing nosocomial infections control of hospitals within a medical alliance.Methods:An electronic questionnaire was customized for online survey of 91 hospitals affiliated to eight regional medical alliances in Changzhou city in March 2019. The survey covered such aspects as general conditions of the hospital, profile of nosocomial infection control administrators and other staffing, supervision of hospital nosocomial infection programs, and training needs, as well as outstanding problems and suggestions.Frequency number and percentage represent enumeration data, and χ2 test was used to analyze the in-group differences of medical institutions of three levels. Results:Tertiary public hospitals were superior to the secondary and primary hospitals in organizational structure, professional staffing and target monitoring, with the differences of statistical significance( P<0.05). The most urgent training needs of medical institutions at all levels were knowledge in determination and reporting of infectious diseases/nosocomial infection/infection outbreaks; top imperatives and recommendations were development of operation rules for primary medical institutions and standardization of workflows. Conclusions:Staff of primary medical institutions need capacity building in nosocomial infection control; primary hospitals are equipped with incomplete nosocomial infection control information platform; key departments in general lack homogenous management. Tertiary hospitals are encouraged to play leadership in medical alliances in achieving standardized, homogenous and informationized nosocomial infection control within the medical alliances.

ABSTRACT

The anoikis resistance confers the ability of cancer cells to survive and metastasize in the blood circulation without adhesion,but its effect and mechanism in intrahepatic and distant metastasis of hepatocellular carcinoma has not been fully elucidated.Recent studies have shown that certain factors or drugs may inhibit anoikis of hepatoma cells through some signaling pathways.These signaling pathways are not completely separated,they are interconnected to promote metastasis of hepatocellular carcinoma.Liver is the metabolic center of many substances,and many related factors can promote metastasis of hepatocellular carcinoma through inhibiting anoikis.In this review,we summarized the signaling pathways of anoikis resistance of hepatocellular carcinoma.

ABSTRACT

Objective To evaluate the impact of cardiopulmonary resuscitation (CPR) training on the willingness to perform on-site rescue for patients with apnea and cardiac arrest. Methods Through questionnaire survey, the analyses on the differences in the results of evaluating various indicators in CPR Willingness Questionnaire in 364 willingness (including 14 recurrent training personnel) of Yunnan Emergency Center from January 2017 to June 2018 before and after CPR training were carried out in order to observe the impact of training on willingness CPR willingness. Results A total of 364 questionnaires were distributed and 364 valid questionnaires were recovered, with a recovery rate of 100%. Compared with those before the CPR training, the analyses of the contents of the questionnaire showed that the proportions of following 6 types of volunteer who were reluctant to implement CPR on site begore training were significantly lower after CPR training [no confidence in their own operational skills: 20.3% (74/364) vs. 83.2% (303/364), being impossible to identify the patients requiring CPR: 25.5% (93/364) vs. 87.1% (317/364), fear of mouth-to-mouth artificial respiration to contract infectious diseases: 30.2% (110/364) vs. 82.4% (300/364), worried about chest compressions leading to bone fractures: 23.3% (85/364) vs. 86.8% (316/364), worried about the inaccurate positioning of chest compressions: 12.4% (45/364) vs. 82.4% (300/364) and fear of taking legal responsibility: 14.3% (52/364) vs. 89.8% (327/364)], and the differences were statistically significant (all P < 0.05); after training, the following 3 kinds of proportions of carrying out CPR were much higher than those before training [volunteers were willing to implement CPR on site for strangers: 83.2% (303/364) vs. 54.9% (200/364), volunteers were willing to implement CPR on site for friends, colleagues, classmates and other acquaintances: 83.5% (304/364) vs. 58.2% (212/364), volunteers were willing to implement CPR on site for family members: 84.6% (308/364) vs. 61.8% (225/364)], the differences being statistically significant (all P < 0.05). Conclusion CPR training for volunteers can improve their willingness to perform on-site rescue for patients with apnea and cardiac arrest, but there are still partial barriers of CPR willingness for strangers.

Through the comparative study of the test scores under different teaching methods before and after the examination reform, the SPSS 22.0 statistical software was used to analyze the structure, reliability, difficulty and level of differentiation of the examine papers via t tests. Results Examination papers after the reform showed an increase in difficulty in all question types; some question types also had higher levels of differentiation. Students receiving PBL-based education had higher scores compared to those under traditional teaching methods. The difference was statistically significant. Conclusion PBL teaching mode is more conducive to the mastering of knowledge points and helps students improve grades in objective questions. Medical schools should increase the use of PBL teaching reform in psychiatry courses and conduct examination reform, so as to improve the teaching effect and the passing rate of Practitioners Examination.
