Objective To exPlore the efficacy of nutritional interVention in Patients with chronic obstructiVe Pulmonary disease (COPD) and malnutrition risks. Methods From Jan. ,2008 to Dec. ,2012,829 COPD Patients with NRS2002 score≥3 in Qinzhou Second PeoPle's HosPital were enrolled in this study. Patients were randomized into control grouP (254 cases) and treatment grouP (575 cases) by random numerical table of SPSS 13. 0 statistic software. Patients without contraindication to enteral nutrition were giVen enteral nutrition suPPort,while those with contraindication to enteral nutrition were giVen Parenteral nutrition suPPort. Patients in the treatment grouP receiVed intensiVe suPPort with fortified nutrition,whereas Patients in the control grouP receiVed routine nutrition treatment. All other treatment methods were the same between the two grouPs. TelePhone follow_uP lasted for 3 years in both grouPs after discharge. Patients in the treatment grouP with NRS2002 score≥3 were giVen guidance on nutrition food intake. No nutrition guide was giVen to the control grouP. Times of acute attack,times and duration of mechanical Ventilation,mortality rate,and NRS2002 score three years after the treatment were comPared between the two grouPs. Data were analyzed by multi_factor Logistic regression analysis to understand the nutritional factors of COPD Patients affecting their mortality rate. Results After 3 years of follow_uP,times of acute attack,times and duration of mechanical Ventilation were lower in the treatment grouP than in the control grouP. Mortality rate was significantly lower in the treatment grouP (0. 696%) than the control grouP (4. 724%). After treatment,NRS2002 score was PositiVely correlated with mortality rate of COPD Patients with malnutrition risks. Conclusion For the COPD Patients with malnutrition risks, actiVe nutritional interVention can imProVe their nutrition status ( lower NRS2002 score) ,increase the number of resPiratory muscles to alleViate anoxia,enhance cellular immune function, and thus imProVe their Prognosis.

The Uncariae Ramulus Cum Uncis is a commonly used traditional Chinese medicine. In recent years, many studies have revealed its prominent neuroprotection function. The active ingredients in Uncariae Ramulus Cum Uncis could protect the nervous system in a multi-path and multi-target manner. Uncariae Ramulus Cum Uncis shows the neuroprotective effect by resisting oxidation, scavenging free radicals, modulating neurotransmitters and their related receptors, regulating the inflammatory factors and their related pathways, attenuating neuron apoptosis, reducing intracellular Ca2+ overloads and mitigating neurodegeneration. In this paper, the authors summarized the advance in studies on neuroprotective mechanisms of Uncariae Ramulus Cum Uncis.

The efficacy and safety of uric-acid-lowering therapy (UALT) on slowing the progression of chronic kidney disease (CKD) accompanied by hyperuricemia were assessed. We searched Cochrane Library, PubMed, EMbase, CNKI, Wanfang and Vip databases up to November 15, 2012 for randomized controlled trials (RCTs) which compared the effect of UALT to control therapy in hyperuricemic patients secondary to CKD, and then performed quality evaluation and meta-analysis on the included studies. Seven RCTs involving 451 cases were included. UALT delayed the increase of serum creatinine (MD=-62.55 μmol/L, 95% CI: -98.10 to -26.99) and blood urea nitrogen (MD= -6.15 mmol/L, 95% CI: -8.17 to -4.13) as well as the decrease of glomerular filtration rate [MD=5.65 mL/(min·1.73 m2), 95% CI: 1.88 to 9.41], decreased systolic blood pressure (SBP) (MD= -6.08 mmHg, 95% CI: -11.67 to -0.49), and reduced the risk of the renal disease progression (RR=0.30, 95% CI: 0.19 to 0.46). However, there was no statistically significant difference in 24-h urinary protein quantity and diastolic blood pressure (P>0.05). We identified that UALT could delay the progression of CKD with secondary hyperuricemia. And this also indirectly proved that hyperuricemia was a risk factor for the CKD progression.

BACKGROUND: At present, there is few reports about using middl ecerebral artery obstraction (MCAO) model to determine the repair course of cerebral infarction during functional training.OBJECTIVE: To determine the effect of electro-stimulating therapy on promoting the rehabilitation of cerebral infarction and its mechanism.DESIGN: Randomized controlled study.SETTING: Animal Center and Electron Microscope Laboratory of Zhongshan University.MATERIALS: The experiment was carried out in the Animal Center of Zhongshan Medical College and Neurological Laboratory of the First Affiliated Hospital of Zhongshang University from January 2002 to December2004. A total of 200 healthy males SD rats, aged 3 months and weighing 90-110 g, were selected. According to the following criteria: SBP＞180mmHg (1 mmHg=0.133 kPa), BWT score of MCAO models which were reproduced by RHRSP was 1, totally 180 RHRSP were admitted to the research and divided into electro-stimulating therapy group (n=90) and control group (n=90).METHODS: Electro-stimulating was given to four accupuncture points of the paralyzed limbs of rats. The electro-stimulating treatment was given about 30 minutes once a day. And a therapy course was 6 days, and between two therapy courses there was one-day break. At the end of 1st, 3rd,6th and 9th therapy courses, the brain of motor function and tissue in marginal zone of cerebral infarction were assayed as follow: [1] The beam walking test (BWT, 1 as severe disorder and 7 as normal). [2] Electron microscope. [3] Astrpcyte glial fibriliary acidic protein, neurofilament protein and microtubule-associated protein-2 were assayed with immunohistochemistry. Five fields of each slice in the two groups were randomly selected to add up the positive cell number. Totally 30 positive cells of glial fibriliary acidic protein was selected to assay average absorbency (A) of positive cellular plasm. [4] Apoptosis of neurons were observed with in situ end-labeling (ISEL). [5] Brain-micro vasodilatatio was observed according to the criteria of one complete microvessel account under the field.MAIN OUTCOME MEASURES: [1] Scores of motor function; [2] Ultramicrostructure of cranial neurons and astrocyte; [3] Cranial glial fibriliary acidic protein, neurofilament protein and microtubule-associated protein-2;[4] Apoptosis of neurons; [5] Diastole of cerebral microvessel.RESULTS: Totally 180 rats were eligible while 20 rats were excluded because of their BWT score＞1 after MCAO operation. [1] Results of beam walking test (BWT): Functional recovery of paralysis limbs in electric stimulation group was better than that in control group from the third to the ninth course. In the ninth course, 6 points of rats in electric stimulation group was more than that in control group (42, 46, χ2=15.4, P ＜ 0.01). [2]Positive absorbency of cerebral glial fibriliary acidic protein: That in electric stimulation group was higher than that in control group in the 3rd, 6th,and 9th [(52.97±0.59)% vs (46.40±0.56)%; (49.44±0.80)% vs (46.40±0.56)%;(43.25±0.48)% vs (34.20±0.50)%, P ＜ 0.05]. [3] Assay of neurofilament protein: That in electric stimulation group was higher than that in control group in the 6th and 9th course [(22.9±2.7)% vs (11.9±2.3)%; (26.5±1.7)%vs (11.7±1.5)%, P ＜ 0.05]. [4] Assay of microtubule-associated protein-2:That in electric stimulation group was higher than that in control group in the 6th and 9th course [(21.7±1.3)% vs (11.3±1.1)%; (24.4±2.1)% vs(11.9±2.3)%, P ＜ 0.05]. [5] Apoptosis of neurons: There was not significantly different between the two groups. [6] Results of open number of cerebral microvessel: That in electric stimulation group was higher than that in control group in the 1st, 3rd, 6th and 9th course (33 vs 19; 48 vs 31;45 vs 25; 46 vs 23, Z=-2.309, P ＜ 0.05).CONCLUSION: Electro-stimulating treatment can promote motor function of paralyzed limbs, which was due to that electro-stimulating treatment may promote extinction of the swollen feet of astrocytes, reinforce neurons activity and arouse the dilatation of cerebral capillary which promote the microvascular dilatation in order to improve cerebral blood circulation.

Objective To investigate the antagonistic effect of ω-3PUFAs on cognitive impairment in MK-801-induced schizophrenia (SZ) rats and its mechanism.Methods Rat model of schizophrenia was induced by MK-801.Morris water maze was used to detect the change of cognitive function in rats.The number of neonatal neurons in hippocampus was detected by Brdu staining.CREB,p-CREB,BDNF,TrkB and p-TrkB levels were detected by Weston Blot.Results MK-801 induced schizophrenia-like cognitive impairment (the escape latency in the water maze test was (6.51±3.10)s for Ctr group,(15.27±6.20)s for Mod group;acrossing times was (4.63±1.06) times for Ctr group,(2.00±1.15) times for Mod group),reduced the number of neonatal neurons in hippocampus (the relative level of neonatal neuron number per unit area,Mod/Ctr was 0.656±0.066) and impaired the CREB/BDNF/TrkB pathway (the relative level of gray value,Mod/Ctr:CREB was 0.393±0.065,p-CREB was 0.591±0.015,BDNF was 0.716±0.115,TrkB was 0.787±0.029,p-TrkB was 0.586±0.013).ω-3PUFAs improved the CREB/BDNF/TrkB pathway activity by increasing CREB and TrKB level and their phosphorylation (the relative level of gray value,Pre/Ctr:CREB was 1.139±0.111,p-CREB was 0.845±0.243,BDNF was 0.864±0.133,TrkB was 0.916±0.022,p-TrkB was 0.952±0.047),and then recovered the number of neonatal neurons in hippocampus (the relative level of neonatal neuron number per unit area,Pre/ Ctr was 1.183±0.101),thereby reduced the cognitive dysfunction in schizophrenia rats(the escape latency in the water maze was (7.44±4.55)s for Pre;acrossing times was (3.86±1.68) times for Pre).Conclusion ω-3PUFAs can relieve the MK-801-induced schizophrenia-like cognitive impairment.

Aim To investigate the up-regulation of miR-22 through Wnt pathway inhibits the proliferation,migration and invasion in human gastric MGC803 cells induced by diallyl disulfide(DADS).Methods The effects of proliferation,migration,and invasion of gastric cancer cells were evaluated by MTT,wound-healing and invasion assays.Online prediction software was applied to search the target gene of miR-22.Luciferase report gene assay was used to assess the target genes Wnt-1 of miR-22.The expressions of Wnt-1,β-catenin and TCF-4 were tested by qRT-PCR and Western blot,respectively.Results MTT showed that DADS and miR-22 notably decreased the proliferation compared with control group(P<0.05).Wound-healing assay showed that DADS and miR-22 could significantly inhibit the migration of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Invasion assay showed that DADS and miR-22 could markedly inhibit the invasion of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Online prediction software to search the target gene exhibited that Wnt-1 may be a target gene of miR-22. Luciferase report gene assay disclosed that Wnt-1 was identified as a direct target of miR-22. Qrt-PCR showed that the expression of Wnt-1 Mrna was respectively down-regulated by DADS and miR-22 compared withcontrol group, especially in miR-22+DADS(P<0.05). Western blot exhibited that DADS and miR-22 obviously suppressed the expressions of Wnt-1, β-catenin and TCF-4 proteins, especially in miR-22+DADS(P<0.05).Conclusion Up-regulation of miR-22 through Wnt pathway can remarkably suppress the proliferation, migration and invasion in MGC803 cells by DADS.

After six‐month follow‐up ,total incidence rate of MACE in health education group was significantly lower than that of routine treatment group (8.9% vs .26.3% ) , P< 0.05. Conclusion:Health education can significantly improve quality of life ,compliance and prognosis in community patients with cor‐onary heart disease ,which is worth clinical extending and use .

Aim To investigate the effects of diallyl di-sulfide( DADS) on G2/M arrest in Chk1/MGC803 and Chk2/MGC803 cells so as to establish stable human gastric cancer MGC803 cells with overexpression of Chk1/2 gene. Methods The colony formation, flow cytometry, RT-PCR and Western blot were used to de-tect the proliferation, cell cycle, and expression of Chk1/2 mRNA and protein, p-Chk1/2, CDC25C and cyclinB1, respectively. Results The colony formation showed that the colony forming efficiency in Chk1/MGC803 and Chk2/MGC803 cells treated by 30 mg· L-1 DADS was lower than in control group and vector group ( P <0. 05 ) . Flow cytometry demonstrated that 41. 3%, 57. 4%, 68. 9% and 42. 9% of G2/M cells in Chk1/MGC803 were increased than in MGC803 and Chk2/MGC803 , respectively after treated by DADS in 12,24, 36 and 48 h(P <0. 05). At the same time, RT-PCR disclosed that expression of Chk1 and Chk2 mRNA had no marked change. Western blot showed that total proteins of Chk1 and Chk2 and p-Chk2 had invisible change, but expression of p-Chk1 was up-reg-ulated, and CDC25C and cyclinB1 were down-regula-ted time-dependently in Chk1/MGC803 cells ( P <0. 05 ) . Conclusion DADS arrests MGC803 cells at G2/M by increasing p-Chk1 expression to cause down-regulation of CDC25C and cyclinB1 simultaneously.
