ObjectiveTo discuss the effect of evidence-based nursing in improvement of unhealthy emotion and treatment compliance of patients undergoing painless gastroscopy. Methods134 patients from May 2008 to December 2010 undergoing painless gastroscopy were chosen as study object.According to voluntariness of the patients and their families,they were divided into the evidence-based nursing group (70 cases) and the routine psychological care group (68 cases).The satisfaction degree with nursing,unhealthy emotion,and the compliance during treatment process were evaluated with SAS and SDS.ResultsThe satisfaction degree of patients in the evidence-based nursing group was 92.86％,higher than 79.41％ in the routine psychological care group.No significant difference was shown in SAS and SDS score before treatment between two groups,but unhealthy emotion and treatment compliance after treatment significantly improved,and the improvement degree of the evidence-based nursing group was more evident. ConclusionsApplication of evidence-based care model in painless gastroscopy has more obvious advantages in improvement of unhealthy emotions and treatment compliance compared with routine nursing.It has more important value for clinical practice and is more conducive to improve the quality of life of patients.

Objective To study the renal damage of patients with juvenile primary Sjgren's syndrome (pSS)and its clinical manifestations,pathologic characteristics with biopsy,treatment and prognosis.Methods Ten patients with juvenile pSS complicated with renal impairments were retrospectively analyzed.Data of these 10 patients were compared with those without renal impairments.Results Ten patients complicated with renal impairments in 24 patients with juvenile pSS,9 of them presented with type I renal tubular acidosis(RTA), 5 with hypokalemia paralysis,3 with calcification of the renal tissue,3 with positive urine protein.1 with dia- betes insipidus.There was no significant difference between patients with renal impairments and those without. Three patients underwent kidney biopsy that showed chronic interstitial nephritis(CIN)with extensive lymp- hoplasmie cell infiltration.Two patients had glomerular lesions and one of them was diagnosed as pSS over- laped with systemic lupus erythematosus(SLE).Steroid and immunosuppressive agents had significantly alle- viated symptoms and the hypergammaglobulinemia was significantly improved.Conclusion Renal impairment may be the major complication in juvenile pSS.The major clinical manifestations are RTA and the glomeruli are involved occasionally.Treatment with steroid anti immunnsuppressive agents should be given to those who have evidence of systemic involvement.

AIM To prepare diosgenin nanosuspensions.METHODS The nanosuspensions prepared by media milling method were solidificated by freeze drying method.With particle size and polydispersity index (PDI) as evaluation indices,stabilizer kind,ratio of diosgenin to stabilizer,ratio of preliminary nanosuspension volume to grinding bead amount,milling time,lyoprotectant kind and its amount as influencing factors,single factor test was applied to screening preparation and solidification processes.The morphology of nanosuspensions was observed,then the particle sizes and polydispersity indices of nanosuspensions and freeze-dried powder were determined.RESULTS The optimal conditions were determined to be 6:1 for ratio of diosgenin to Pluronic F127 (stabilizer Ⅰ),50:1 for ratio of diogenin to sodium dodecyl sulfate (SDS,stabilizer Ⅱ),1:4 for ratio of preliminary nanosuspension volume to grinding bead amount,120 min for milling time,and 8％ PEG-6000 and 2％ mannitol as lyoprotectants.The average particle size and polydispersity index of rod-like or flaky nanosuspensions were (348.1 ±14.2) nm and 0.244 ± 0.059,respectively,which were lower than those of freeze-dried powder.At room temperature,the particle sizes of nanosuspensions and freeze-dried powder remained stable within 35 d and 3 months,respectively.CONCLUSION The physical stability of diosgenin freeze-dried powder is superior to that of its nanosuspensions,which can be used after being reconstituted.

[ABSTRACT]OBJECTIVETo study the mRNA expression of glucocorticoid receptor(GR) in peripheral blood mononuclear cells in patients with obstructive sleep apnea hypopnea syndrome(OSAHS) and its clinical significance. METHODSReal-time fluorescent quantitative PCR was used to detect GRα mRNA and GRβ mRNA exprssion in PBMC of 30 male patients with moderate to severe OSAHS and 27 healthy male subjects. The relationships between the expression of glucocorticoid receptor mRNA and the apnea hypopnea index, body mass index, neck circumference, waist circumference, the lowest oxygen saturation, the average oxygen saturation, the Epworth sleepiness scale(ESS) score, fasting blood glucose, heart rate and blood pressure were analyzed.RESULTSCompared with the control group, the expression level of GRα mRNA was lower in the OSAHS group(t=2.25,P<0.05) and the expression level of GRβmRNA had no difference between the two groups(t=1.43, P>0.05). We had not found the significant correlation between the expression of GRα mRNA and the clinical parameters above in OSAHS patients.CONCLUSIONThe expression of GRα mRNA in PBMC in moderate to severe OSAHS male patients have a downward trend compared with healthy group, but the mechanism remains unclear.

The present study investigated the cellular mechanism underlying the effect of ligustrazine on the ion transport in rat distal colon using the short-circuit current (I(SC)) technique. In freshly isolated colonic strips, basolateral addition of ligustrazine stimulated a rise in I(SC), which was resistant to basolateral application of neuronal sodium channel blocker tetrodotoxin (TTX), but inhibited by 55.2% by basolateral pretreatment with prostaglandin inhibitor indomethacin. The ligustrazine-induced I(SC) increase was inhibited by apical application of Cl(-) channel blockers diphenylamine-2,2'-dicarboxylic acid (DPC) and glibenclamide. Basolaterally administered bumetanide, an inhibitor of Na(+)-K(+)-2 Cl(-) cotransporter, inhibited ligustrazine-evoked current increases by 85.2% and basolateral exposure to Ba(2+), a non-specific potassium channels blocker, and blocked the current by more than 90%, indicating that basolateral Na(+)-K(+)-2 Cl(-) cotransporter and K(+) channels played an important role in the effect of ligustrazine. The results suggested that ligustrazine could stimulate rat distal colon (-) secretion that is mediated by basolateral Na(+)-K(+)-2 Cl(-) cotransporter and K(+) channel.

Objective To evaluate the automatic synthesis of 18F-labeled cyclic RGD peptide c(RGDyK)and its biological distribution in the tumor-bearing mice. Methods N-succinimidyl-4-18 F-fluorobenzoate (18F-SFB) was automatically synthesized and then re-dissolved in acetonitrile (MeCN). The cyclic RGD peptide c(RGDyK) was mixed with an hydrous DMSO and N, N-diisopropyl ethylamine (DIPEA). 18F-FBRGD was obtained by the reaction of peptide solution with 18 F-SFB. The final product was purified by HPLC gradient separation system and solid-phase extraction method. The biodistribution study and competition test of N-4-18F- fluorobenzoyl-RGD (18F-FB-RGD) in the tumor-bearing mice was performed. Results The labeling yield of 18 F-FB-RGD was (33.6 ± 3.5)%. The synthesis time was 110 min. The radiochemical purity was more than 98%. The tumor uptake of 18F-FB-RGD was (3.43 ±0.15), (2.61 ±0.14), (2.11 ±0.13), and (1.79 ±0.18) %ID/g, respectively, at 30, 60, 90 and 120 min after injection. The ratio of tumor to muscle activity ranged from 4.26 ±0.69 to 5.80 ±0.78. The tumor uptake decreased dramatically after RGD blockage. The uptake was (0.46 ±0.21) %ID/g and (2.87 ±0.59) %ID/g in the blocked and unblocked mice, respectively, at 60 min after blockage. Conclusions 18 F-FB-RGD can be automatically synthesized and it may become a promising tumor imaging agent.

OBJECTIVETo explore the relationship between plasma low-density lipoprotein (LDL) and oxidized low-density lipoprotein (ox-LDL) levels and the severity of coronary atherosclerosis.

METHODSFasting plasma ox-LDL was measured by enzyme-linked immunosorbent assay and plasma LDL was measured by biochemical autoanalyser in 31 patients with coronary artery spasm (CAS group, chest pain with positive acetylcholine provocation test but without significant coronary artery stenosis), 35 patients with stable angina pectoris (SAP group) and 24 healthy persons (control group).

RESULTSPlasma LDL levels were similar between CAS and SAP groups but significantly higher than that in control group. Plasma ox-LDL levels significantly increased in proportion to coronary lesion severities [SAP (575 +/- 219 microg/L) > CAS (299 +/- 117 microg/L) > control (218 +/- 35 microg/L)]. In SAP group, plasma ox-LDL level was also significantly higher in multi-vessel disease group than that in single-vessel disease group (672 +/- 92 vs. 462 +/- 72 microg/L, P < 0.05).

CONCLUSIONPlasma ox-LDL but not LDL level is significantly correlated to the severity of coronary atherosclerosis and should therefore be the focused therapy target in patients with coronary artery disease.
