Objective To study the influence of climate, geographical environment and harvesting time on contents of schaftoside in Desmodium styracifolium Herba. Methods Content of schaftoside in Desmodium styracifolium Herba was determined by using HPLC. ODS-C18 column (4. 6 mmí250 mm,5 μm) was used, the mobile phase was methanol-water (3268), the detection wavelength was 272 nm, the flow rate was 0. 5 mL·min-1, and the column temperature was 35℃. Results The climate type, amount of precipitation, average temperature, duration of sunshine, geographical environment of different province had significant impacts on the content of schaftoside in Desmodium styracifolium Herba. Conclusion Subtropical monsoon climate, temperature from 25 ℃ to 32 ℃, sunshine time of 10 h per day and the average annual rainfall of 1 942 mm are suitable for growth of Desmodium styracifolium. The content of schaftoside in samples cultivated from Guangxi Province is higher than that cultivated from Guangdong Province and Hainan Province. The schaftoside content of sample cultivated in July is higher than that cultivated in other months.

Objective To investigate the expression and significance of aromatase P450,COX-2,ER and PR in the patients with adenomysis.Methods The immunohistochemistry staining was used to detect the expression of aromatase P450,COX-2,ER and PR in ectopic endometrium and eutopic endometrium of 30 patients with adenomyosis and 30 cases in control group.Results The expression of aromatase P450,COX-2 in ectopic endometrium were significantly higher than those in eutopic endometrium (all P ＜ 0.05) ; The expression of ER,PR in ectopic endometrium were significantly lower than those in eutopic endometrium (all P ＜ 0.05),excepted the expression of PR in eutopic endometrium,the expressions of both ER and PR lose their periodical cycle.There was positive correlation between the expression of aromatase P450 and COX-2 in adenomysis group(P ＜ 0.05).In adenomyosis,the expression of aromatase P450,COX-2,ER and PR in dysmenorrhea subgroup were significantly higher than those in non-dys menorrhea subgroup(all P ＜ 0.05).Conclusion Aromatase P450,COX-2 and ER play important roles in the genesis and development of adenomyosis and dysmenorrheal,PR is not the main pathogenic factors of adenomyosis.The expressions of aromatase P450,COX-2 and ER in adenomyosis have nothing to do with endometrial cyclical change and are not subject to the regulation of ovarian hormones.

Objective To analyze the clinical,endoscopic,and pathological features of aged patients with ulcerative colitis and the difference between the aged and non-aged patients. Methods The clinical,endoscopic,and pathological data from 349 ulcerative colitis patients admitted in Huadong Hospital from January 2000 to December 2008 were reviewed and analyzed retrospectively. The patients were divided into two groups: aged group (≥60 years) and non-aged group (0.05) between the two groups. The disease of aged patients was less severe than that of the non-aged patients (P0.05). The occurrence of dysplasia in the aged patients was higher than that in the non-aged patients (P

ObjectiveTo evaluate the diagnostic value of “taller-than-wide sign” of thyroid malignancy in transverse and longitudinal plane using ultrasound.Methods708 thyroid lesions including 302 benign nodules and 406 malignant nodules ( 390 papillary carcinomas,12 medullary carcinomas,4 follicular carcinomas) that were diagnosed at surgery were included in this study.The sensitivity and specificity of “taller-than-wide sign” in transverse (A/TC ≥ 1 ) and longitudinal plane (A/TL ≥ 1 ) were evaluated using ultrasound.All thyroid malignant lesions were divided into three groups according to size of the nodules:group A≤1 cm; group B≤2 cm,group C＞2 cm.The sensitivity of each group was also evaluated.ResultsThe constituent ratio of “taller-than-wide sign” between benign and malignant nodules was significantly different (P＜0.001 ).The differences of sensitivity of A/TL ≥ 1 and A/TC ≥ 1 among three groups were also found( P ＜0.001),and the sensitivity of A/Tc≥1 was higher than A/TL≥1.ConclusionsA/TC≥1 found by ultrasound contributes to differentiate the thyroid carcinoma from benign nodules.For a large thyroid lesion,other indicators are needed to diagnose thyroid carcinoma.

Objectives To evaluate the efficacy and safety of administering Ivabradine in the elder patients with chronic heart failure(HF).Methods Totally 52 outpatients with chronic stable HF in Fuwai Hospital and Anzhen Hospital from August 2015 to February 2016,with heart rates (HR)of ＞70 bpmafter optimized medical therapy were selected and administrated Ivabradine for 3 months(Ivabradine group).50 patients who received optimized medical therapy except Ivabradine for economic or other reasons were recruited as control group during the same period.Initial dose of Ivabradine was 2.5 mg two times a day,up to a maximum of 7.5 mg two times a day,adjusting the dose according to HR.Resting HR of the patients was maintained around 60 beats/min and not lower than 55 beats/min.HR,N-terminal pro-brain natriuretic peptide (NT-proBNP),6-minute walk distance,Minnesota heart failure quality of life(MLHFQ),left ventricular ejection fraction(LVEF) and adverse effects were recorded.Results At baseline,no significant differences were found in HR,NT-proBNP,the scores of MLHFQ,6-minute walk distance (all P＞ 0.05) between Ivabradine group and control group.After 3 months of treatment,compared with control group,Ivabradine group showed significantly decreased levels of HR,the scores of MLHFQ and NT-proBNP(allP＜0.01),and significantly increased 6-minute walk distance and LVEF(all P＜0.01).Compared with baseline data,Ivabradine treatment showed the decreased levels of HR [(69.5 ± 10.2)bpm vs.(80.2 ± 7.8)bpm,P＜0.05],the scores of MLHFQ [(14.9±4.3)scores vs.(23.5±6.2)scores(P＜0.05)]and NT-proBNP [1 682 ng/L (212-3 628) vs.2 450 (254-5 344) ng/L,P ＜ 0.05] significantly,and showed the significantly increased levels of 6-minute walk distance [(386.4 ± 101.8)m vs.(282.9 ± 86.3)m,P＜ 0.05]and LVEF [(40.0±6.0)％vs.(31.0±7.0)％ (P＜0.05)].Few adverse effects were recorded.Conclusions In elderly outpatients with stable HF,Ivabradine treatment is effective and safe.

Background:Colonoscopy is considered as a standard method for detecting various kinds of colorectal polyps. However,conventional colonoscopy( CC)still has the chance to miss some lesions. Literatures have already reported that transparent hood assisted colonoscopy( THAC)can improve the detection of colorectal polyps. However,the effect of black hood assisted colonoscopy( BHAC)on detection of colorectal polyps is still unclear. Aims:To evaluate the effect of BHAC on detection of colorectal polyps. Methods:A total of 1 076 patients underwent CC and BHAC from Sept. 2014 to April 2015 at Huadong Hospital Affiliated to Fudan University were enrolled in this prospective randomized controlled study. Baseline characteristics,cecal intubation time,withdrawal time,number of polyps,detection rate of polyps,location, size,morphology and pathological diagnosis of polyps between two groups were compared. Results:Compared with CC group,cecal intubation time was significantly shorter in BHAC group than in CC group[(6. 31 ± 3. 51)min vs.(7. 05 ± 4. 15)min,P=0. 002]. No significant differences in withdrawal time and rate of cecal intubation were found between two groups(P>0. 05). Detection rate of polyps was significantly higher in BHAC group than in CC group(65. 4% vs. 48. 7%,P=0. 004). No significant differences in size,morphology of polyps were found between two groups(P>0. 05). Conclusions:Compared with CC,BHAC could significantly improve the detection of colorectal polyps,and shorten cecal intubation time.

OBJECTIVETo investigate the applications of percutaneous screw fixation for the treatment of pelvic fractures and its related surgical considerations.

METHODSFrom June 2010 to June 2012,19 patients with pelvic fractures were treated with percutaneous hollow screws. There were 13 males and 6 females, with an average age of 41 years (ranged from 22 to 58 years). Fractures were caused by traffic accidents in 11 cases, by falling down from high place in 8 cases. Based on the Tile classification, there were 15 cases of Tile C type and 4 case of Tile B type. The indexes such as screw inserting time, intraoperative blood loss, complications, functional recovery and reduction conditions were observed. Fixation methods included sacroiliac screws, cannulated screw fixation of the pubic ramus and cannulated screw fixation of the pubic symphysis separation.

RESULTSAnatomical reduction achieved in 7 cases, satisfactory reduction 11 cases, and unsatisfactory reduction 1 case. Union time of fracture union ranged from 8 to 12 weeks (mean 10 weeks). Wound infection,ununion of fracture and nerve injuries were not found. According to the Majeed standards, 12 patients obtained an excellent results, 6 good and 1 fair.

CONCLUSIONPercutaneous screw fixation for the treatment of pelvic fractures under fluoroscopy has several advantages such as less trauma, less blood loss, fewer rates of complications, reliable fixation and no blood transfusion, which can reconstruct the stability of the pelvic ring, but it needs adequate preoperative preparation and high requirements for the surgeon.

OBJECTIVETo investigate the effect of SIRT6/NF-κB signal axis in delaying hematopoietic stem/progenitor cell senescence with ginsenoside Rg1, in order to provide theatrical and experimental basis for looking for methods for delaying HSC senescence.

METHODSca-1 + HSC/HPC was isolated by magnetic cell sorting (MACS) and divided into five groups: the normal control group, the aging group, the positive control group, the Rg1 anti-senescence group, and the Rg1-treated group. Senescence-associated β-galactosidase (SA-β-Gal) staining, cell cycle analysis and hemopoietic progenitor cell mix (CFU-Mix) were adopted to determine the effect Rg1 in delaying or treating Sca-1 + HSC/HPC senescence biology. The mRNA and protein of senescence regulation molecules SIRT6 and NF-KB were examined by realtime fluorescence quantitative PCR (FQ-PCR) and western blotting.

RESULTCompared with the senescence group, the Rg1 anti-senescence group and the Rg1-treated group showed lower percentage in SA-β-Gal-stained positive cells, decreased cell proportion in G1 phase, increased number of CFU-Mix, up-regulated in SIRT6 mRNA and protein expression, down-regulation in NF-KB mRNA and protein expression. The Rg1 anti-senescence group showed more evident changes in indexes than the Rg1-treated group.

CONCLUSIONRg, may inhibit Sca-1 + HSC/HPC senescence induced by t-BHP by regulating SIRT6/NF-KB signal path.
