Objective To evaluate the preoperative nutritional status of the patients which were preparing for cardiac valves replacement using nutrition risk screening 2002 (NRS2002),and analyze the evaluation effect and bring forward the corresponding nursing interventions.Methods 226 patients who would carry out cardiac valves replacement in the context of extracorporeal circulation were evaluated by NRS2002 preoperatively.88 patients had nutrition risk.Those elective 88 patients were randomly assigned into the experimental group and the control group,each had 44 cases.Then different nursing measures were implemented in each group and the clinical outcome was contrasted in the two groups.Results In the patients who were preparing for cardiac valves replacement,88 cases had preoperative nutrition risk score ≥3 points and 138 cases ＜ 3 points.Preoperative nutrition risk score had positive correlation with heart function grade.Difference of the experimental group and the control group in length of stay,length of mechanical ventilation after surgery and incidence rate of general complications had statistical significance.Conclusions It is effective to analyze the preoperative nutritional status of the patients with cardiac valves replacement by NRS2002.It may improve prognosis effectively by providing preoperative nursing interventions for patients with nutrition risk.Besides,it provides theoretical basis for further studying the relation between nutrition support and clinical outcome of patients with nutrition risk.

AIM: To examine the expression of miRNA-22 in the ovarian tissues and the effect of miRNA-22 over-expression on the proliferation, migration and invasion in SKOV-3 cells.METHODS: The expression levels of miRNA-22 in different ovarian tissues and SKOV-3 cells were determined by qPCR .miRNA-22 was over-expressed by trans-fection of miRNA-22 mimic.The cell viability was examined by CCK-8 assay.The cell migration was measured by wound healing test .The cell invasion was analyzed by Transwell assay .The protein expression levels of VEGF and P 53 were deter-mined by Western blot .RESULTS: Compared with the normal ovarian tissue , the expression level of miRNA-22 was remarkably decreased in the ovarian tumor tissues .After transfection with miRNA-22 mimic, the expression level of miRNA-22 in the SKOV-3 cells was significantly increased , while the cell viability , migration and invasion were obviously decreased .Moreover , the protein expression of VEGF and P 53 was dramatically inhibited after over-expression of miRNA-22.CONCLUSION:The decreased miRNA-22 expression may be correlated with the development of ovarian can-cer.Over-expression of miRNA-22 decreases the cell viability , migration and invasion by reducing the protein expression of VEGF and P53.

Objective To establish a reproducible rat model of acute rectal mucosal injury induced by acetic acid. Methods Fifteen healthy Sprague-Dawley rats were randomly divided into the control group (3 rats) and experimental group (12 rats).Acute rectal mucosal injury was induced by 4%acetic acid using a cotton swab inserted into the rat rec-tum for 1 min to a depth of 3 cm.The morphological characteristics were analyzed by the naked eye and histology at 0.5 h and 1, 4, and 6 days after acetic acid intervention.Results All rats survived 6-day study period.The successful rate of model establishment was 100%.From 0.5 h to 1st day after acetic acid intervention, the gross morphology of recta showed congestion, edema and ulcer to ulcer complicated with hemorrhage.The histology showed necrosis and hemorrhage of the epithelial tissue of the mucosa to complete and extensive necrosis of the mucosa.The glandular structure showed partial to complete loss.The submucosa showed edema to edema complicated with hemorrhage and congestion.The interstitial tissues showed vasodilatation and congestion to inflammatory cell invasion.From 4 to 6 days after acetic acid intervention, the rectal mucosal changes were obviously improved.Epithelial and glandular regeneration and inflammatory granulation occurred, but not fully recovered, some edema and redness, partial lack of glands were still present.Conclusions 4%acetic acid for 1 min can be used to successfully induce rat model of acute rectal mucosal injury.This procedure is easy to operate, with a high success rate,reproducible, and the alterations are lasting more than 6 days.This animal model is very suitable for rapid screening of topical drugs for the treatment for rectal mucosal injury.

Objective To investigate the effect of blockading OX40-OX40L co-stimulatory signaling on the survival time of liver allograft in rat.Methods siRNA-expression vectors were constructed to targeting OX40.3～5 minutes before DA to Lewis orthotopic liver transplantation was performed,5×109 pfu of targeting OX40 siRNA plasmid DNA were diluted in 5 ml of phosphate buffered saline(PBS)and inlected intravenously into recipient Lewis rat over a period of 10 seconds.Serum IL-2 and IFN-γ levels were assayed by ELISA,and mix lymphocyte response(MLR)were tested by 3H-thymidine.Results The survival time of recipients in siRNA treatment group(74.0±9.3)was significantly longer than that in control group[(7.3±0.5)days].In experiment group,the inflammatory cell infihration and liver tissue structure destruction were very slight.The concentration of serum IL-2 was much lower in siRNA treatment group[(46±8.4)pg/ml]than that in control group[(286.5±14.6)pg/ml].Meanwhile,the concentration of serum IFN-γ was much lower in siRNA treatment group [(202.7±14.6)pg/ml]than that in control group[(1682.7±87.9)pg/ml].Conclusion Administration of OX40-siRNA can blockade OX40-OX40L co-stimulatory signaling pathway.hence inhibit the rejection of liver allograft.

OBJECTIVETo study the effect of Yishen Daluo Decoction (YDD) on the expression of protein lipoprotein (PLP), oligodendrocyte transcription factor 1 (Olig 1), and oligodendrocyte transcription factor 2 (Olig2) in mice with experimental autoimmune encephalomyelitis (EAE).

METHODSTotally 40 mice were randomly divided into 4 groups, i.e., the normal group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 mice in each group. Each mouse in the model, CM, and WM groups was subcutaneously injected with 200 microL antigen emulsion (containing 150 micro g PLP139 -151 and 400 micro g H37RA) in two parts at the upper abdomen on the first day. 100 microLBordetella pertussis juice (containing 0. 6 x 10(6) Bordetella pertussis) was injected by caudal vein on the first and the third day. On the 7th day after modeling, each mouse in the normal group and the model group was intragastrically given normal saline (0. 1 mL/10 g). YDD (0. 2 g crude drug/10 g) was intragastrically given to mice in the CM group, and prednisone (0. 039 mg/10 g) was intragastrically given to mice in the WM group. All mice were intervened for 54 days. Changes of PLP, Olig1, and Olig2 in the brain tissue of EAE mice were detected by Western blot. Results The levels of PLP and Olig2 in the brain tissue of the model group were less than those of the normal group (P <0.05). Compared with the model group, the levels of PLP, Olig1, and Olig2 in the brain tissue increased in the CM group (P <0.05); the levels of PLP and Olig2 in the brain tissue increased in the WM group (P <0.05). Compared with the WM group, the level of Olig1 in the brain tissue increased in the CM group (P <0.05).

CONCLUSIONYDD could enhance remyelination by elevating the levels of Olig1 and Olig2 in the brain tissue of EAE mice.

OBJECTIVETo explore the diagnostic value of the radiologic characteristics of osteoporotic Kummell's disease.

METHODSTotal 16 patients with pathologically confirmed osteoporotic Kummell's diseases were reviewed from May 2010 to May 2012, including 4 males and 12 females with the mean age of 73.4 years (ranged, 67 to 83 years old). Radiologic imagings of all patients, including X-ray, CT and MRI, were analyzed retrospectively.

RESULTSIntravertebral linear clefts could be seen on the AP and lateral X-ray films of vertebrae. Sagittal and axial CT scans demonstrated the vacuum cleft phenomenon with liquid and air was identified within the vertebral body. Sagittal MRI showed the callapsed vertebral segment and the area of fluid signal with clear and intact border within the vertebral body. The fluid signal was low on T1-weighted images and high on T2-weighted images and stir images, which was corresponding to an intravertebral vacuum cleft.

CONCLUSIONThe radiologic characteristics of Kurmmell's diseases can provide valuable evidences for the early diagnosis.

Objective To evaluate influence of Azithromycin on breath hydrogen test(BHT) in acute upper respiratory infection(AURI) in Children.Methods Fasting BHT and lacunose BHT were respectively performed by using HD-1 breath hydrogen detector for 38 inpatients before and after receiving Azithromycin.Fasting BHT of 115 healthy controls were determined.Results After Azithromycin was given,Fasting BHT was lower than that before Azithromycin used(P

Objective:To investigate the effect of a 2-year resistance and aerobic training on reducing the risk of cardiovascular disease in patients with prediabetes.Methods:A total of 248 patients with prediabetes were enrolled from Chinese and Western Medicine Hospital Affiliated to Nanjing University of Chinese Medicine from January to April 2014, and Danyang People′s Hospital and The First Affiliated Hospital of Guangxi Medical University from May to December 2014.Based on random number table method, the patients were divided into 3 groups: the resistance training group (RT group, 82 cases), the aerobic training group (AT group, 83 cases) and control group (83 cases). Participants in the RT group and the AT group underwent a total of 24 months of exercise training. Changes in indicators (blood glucose,blood lipid, etc.) at baseline and the end of 12 and 24 months among the groups were compared.Results:After intervention, glycosylated hemoglobin (HbA1c), low density lipoprotein cholesterol (LDL-C), blood pressure and homeostasis model 2 insulin resistance index (HOMA2-IR) in the RT and AT groups tended to decrease, and the steady state model 2 β cell function index (HOMA2-β) tended to increase. At the end of 24 months, HbA1c [5.80 (5.43, 6.20) %, 5.70 (5.50, 6.00)% vs. 6.20 (5.70, 6.60) %, all P≤ 0.01], LDL-C [3.07 (2.69, 3.58) mmol/L, 2.97 (2.62, 3.95) mmol/L vs. 3.21(2.54, 3.78) mmol/L, all P<0.05] and HOMA2-IR [0.96 (0.82, 1.47), 1.20 (0.99, 1.43) vs. 1.34 (1.09, 1.51), all P<0.05] were significantly decreased in the RT and AT groups than in the control group. In addition, HOMA2-β [84.50 (60.55, 107.33), 93.00 (78.60, 119.75) vs. 53.40 (37.70, 80.40), all P = 0.001] was significantly increased in the AT and RT groups compared with that in the control group. There were no significant differences in triglyceride (TG) and high-density lipoproteincholesterol (HDL-C) levels between the training groups and the control group (all P>0.05). After adjusting for age, sex and blood pressure, the cardiovascular risk of prediabetes was significantly reduced in RT ( P =0.017) and AT groups ( P =0.018). The Cox regression analyses showed that both the resistance training (HR=0.419, 95 %CI =0.415-0.942, P=0.037) and the aerobic training ( HR=0.310, 95 %CI=0.447-0.866, P=0.026) were protective factors for cardiovascular disease in prediabetic patients after adjustment of age, sex, statins, body mass index and waist-to-hip ratio, which reduced the risks of cardiovascular disease in prediabetic patients by 58.1% and 69.0%, respectively. Conclusions:Two years of aerobic and resistance training interventions have obvious advantages on glycemic and insulin resistance control in prediabetes patients. The resistance training can reduce the risk of cardiovascular disease, and it is, thus, recommended for prediabetic patients without obvious exercise contraindications.

OBJECTIVETo compare the clinical efficacy differences between fire needling technique of filiform needle at high stress points and regular acupuncture on chrondromalacia patellae so as to provide the better therapy for the treatment of this disease.

METHODSSixty cases of chrondromalacia patellae were randomized into a fire needling group (28 cases) and a routine acupuncture group (32 cases). In the fire needling group, 5 to 6 high stress points were localized according to the symptoms, palpation and imaging condition and were stimulated with fire needling technique of filiform needle. The treatment was given once every two days, 5 treatments made one session. In the routine acupuncture group, the regular acupuncture was applied at Dubi (ST 35), Xiguan (LR 7), Yanglingquan (GB 34), Yinlingquan (SP 9), Zusanli (ST 36), etc. The treatment was given once every day, 5 treatments made one session. Lysholm score, VSA score, patella title angle (PTA) and lateral patella angle (LPA) of the affected knees before and after treatment, as well as the clinical efficacy after treatment were observed in the two groups.

RESULTSAfter treatment, Lysholm score, VSA score, PTA and LPA were all improved apparently in the two groups (all P < 0.01). After the treatments, the improvements in Lysholm score, VSA score, PTA and LPA in the fire needling group were more obvious than those in the routine acupuncture group (all P < 0.05). The effective rate was 92.9% (26/28) in the fire needling group, better than 87.5% (28/32) in the routine acupuncture group (P < 0.01).

CONCLUSIONThe fire needling technique of filiform needle at the high stress points relieves the clinical symptoms of chrondromalacia patellae and recovers the biodynamical structure of patellae.
