This research is to investigate study the flavonoids from stems of Nelumbo nucifera and the cytotoxic activities of iso- lated compounds. The constituents were separated by column chromatography,and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for cytoxic activities by MTT method. Twelve compounds were isolated and identified as rhamnazin-3-O-beta-D-glucopyranoside (1), luteolin-3', 4'-dimethylether-7-O-beta-D-glucoside (2), kaempferol-3-O-beta-D-xylopyranosyl-(1-->2)-O-beta-D-glucopyranoside (3), quercetin-3,3'-di-O-beta-D-glucopyranoside (4), 1, 8-dihydroxy-3,7-dimethoxyxanthone (5), isorhamnetin-3-O-beta-D-glucopyranoside(6) , kaempferol(7), isorhamnetin (8), quercetin(9), astragalin(10), hyperoside (11) and 1-hy- droxy-3,7,8-trimethoxyxanthone(12). All compounds were isolated from stems of this plant for the first time, and compounds 1-5 were firstly isolated from the family nelumbonaceae. Compounds 24 and 6 showed significant cytotoxic activities against BEL-7402 carcinoma cell lines at a concentration of 1 x 10(-5) mol x L(-1) with the inhibitory rate of 67.36%, 53.25%, 57.78%, 60.13% and 52.11%, respectively.

Objective To evaluate the effect of enteral nutrition support on the nutritional status and clinical outcomes of patiems with dysphagia after stroke.Methods 148 patients with acute stroke and associated dysphagia were enrolled from August 2013 to July 2014 in the Fifth Affiliated Hospital of Zhengzhou University,and randomly divided into 2 groups by drawing lots within 48 hours after admission:enteral nutrition group (n =75,early enteral nutrition support) and control group (n =73,routine diet).The nutritional status (triceps skinfold thickness,levels of serum total protein,albumin and hemoglobin),incidence of lung infection,mortality,and neurological function were compared between the two groups on day 1 and day 21 after admission.Results On day 1 after admission,the triceps skinfold thickness,levels of serum total protein,albumin,and hemoglobin in the enteral nutrition group were not significantly different from those in the control group [(15.4 ±4.1) mm vs.(15.1 ± 3.7) mm,t=1.36,P=0.392; (75.7±2.6) g/Lvs.(76.6±3.1) g/L,t=1.12,P=0.254; (39.2± 1.8) g/Lvs.(38.7±2.1) g/L,t=1.24,P=0.200; (137.4±14.5) g/Lvs.(135.1±15.3) g/L,t=1.01,P =0.461].On day 21 after admission,all the 4 nutrition indicators were significantly higher in the enteral nutrition group than in the control group [(13.5 ±3.9) mmvs.(11.2±4.6) mm,t=2.08,P=0.019; (63.3±4.1) g/Lvs.(57.1±4.7) g/L,t=4.01,P=0.001; (35.7±1.6) g/Lvs.(34.1± 2.0) g/L,t=2.31,P=0.022; (125.7 ±17.9) g/Lvs.(120.3 ±16.7) g/L,t=2.39,P=0.027].The enteral nutrition group showed lower incidence of lung infection,mortality,and reduced scores of American National Institutes of Health Stroke Scale compared with the control group (41.3％ vs.63.2％,x2 =9.69,P =0.002; 15.3％ vs.21.2％,x2=3.27,P=0.014; 11.1 ±4.1 vs.14.7 ±3.9,t=2.98,P=0.007).Conclusions Early enteral nutrition support can improve the nutritional status and outcomes of stroke patients with dysphagia.In addition,early enteral nutrition support may also be helpful for the improvement of the neurological function.

Objective: To investigate the effect of Qihuang herbal warm bag on primary dysmenorrhea. Methods: Thirty-two patients with primary dysmenorrhea were selected as subjects and treated by compression with the herbal warm bag for two months. The curative effect was evaluated, and prostaglandin F2a(PGF2a) and β-endorphin(β-EP) were measured before and after treatment. Results: The herbal warm bag had positive effects on dysmenorrhea at different degrees and could decrease the contents of blood PGF2a and β-EP. Conclusion: The herbal warm bag is quite effective for primary dysmenorrhea possibly by decreasing serum PGF2a and increasing serum β-EP.

Objective: To investigate the efficacy of gemcitabine in chemotherapy of cervical carcinoma. Methods:10 untreated cervical carcinoma patients had been divided into two groups,5 cases were treated with neoadjuvant chemotherapy and radiotherapy,others were treated only with radiotherapy. All patients were operated and compared the pathologic changes of cancers. Moreover 3 cases with recurrent tumors had been treated with gemcitabine and other agents . Results: The rate of complete response(CR) was 60% in group of neoadjuvant chemotherapy and 20% in patients with only radiotherapy. Only one case achieved partial response (PR) in patients with recurrence. Conclusion: The neoadjuvant chemotherapy in cervical carcinoma with gemcitabine is helpful for achieving good response .As radiation sensitizer or radio-potentiator,gemcitabine can promote efficacy of neoadjuvant chemotherapy in cervical carcinoma.

Objective: To study the factors relating the prognosis of ovarian granulosa cell tumor and the characteristics of its clinical presentations. Methods: The clinical records and pathological sections of 24 cases with granulosa cell tumor of ovary were reviewed retrospectively. The clinical characteristics, the clinical stage, and the therapeutic programs and the results were summarized respectively. Results:The 5-years survival rate showed that the clinical stage influenced the prognosis of ovarian granulosa cell tumor obviously. Conclusion: The early dection is the major factor which influences the patients' survival rate.

Objective To discuss the expression of tumor necrosis factor-like weak inducer of apoptosis ( TWEAK) in serum, urine and renal tissue in lupus nephritis( LN) . Methods The serum and urine levels of TWEAK were assessed by ELISA in LN patients and normal controls. Immunohistochemistry was used to detect the expressions of TWEAK in the kidney of patients and healthy controls. Results The serum and urine concentrations of TWEAK and MCP-1 were significantly higher in LN patients than those in healthy controls(P<0. 01). In addition,the level of serum TWEAK showed positive correlation with SLEDAI and negative correlation with serum C3 level ( P <0. 01),the expression of urine TWEAK showed positive correlation with SLEDAI (P<0. 05). In healthy renal tis-sues TWEAK was distributed mainly in renal tubules and rarely seen in glomerular while the expressions of TWEAK increased in renal tubular and glomeruli stainings were found in LN paitients. TWEAK could induce increased mac-rophage migration, may be involved in the pathological progression of lupus nephritis. Conclusion TWEAK may play key roles in the pathogenesis of LN. Meanwhile, TWEAK in serum and urine may be useful as markers of dis-ease activity. The change of TWEAK maybe associated with the pathology category of LN.

Objective To investigate the survival, differentiation and action of neural stem cell transplanted into striatum of Parkinson disease rat model. Methods Neural stem cells were isolated and cultured. The character of self-renewing was confirmed by technique of single cell clone culture. The ability of multi-directional differentiation and specific antigen-nestin was showed by immunocytochemistry(ICC). PD rat models were established, and the DAPI-labelled neural stem cells were transplanted into striatum. The 6-HHDA induced rotary behavior was measured, distribution and migration of the cell were checked by fluoresce activating. ICC and HPLC are used to see its differentiation and action of secrete neurotransmitter dopamine(DA) and it’s metabolites. Results The cultured stem cell express nestin and have the ability of self-renewing and multi-directional differentiation. 6-HHDA induced rotation decreased after transplantation of NSC into the PD rat striatum(P

MicroRNAs(miRNAs)are a group of non-coding RNA molecules having modulating function,and as a post transcriptional modulating factor is involved in the modulation of expression of eukaryotic genes. Inflammatory bowel disease(IBD)is a chronic non-specific intestinal inflammatory disease and its etiology has not yet been fully clarified. Recent studies have shown that circulating miRNAs were specifically expressed in patients with IBD. This article reviewed the advances in studies on circulating miRNAs and IBD.
