ObjectiveTo investigate the effect of nursing intervention on sleep quality of patients after cardiac intervention. Methods140 patients undergoing cardiac interventional surgery in our hospital from January 2010 to January 2011 were chosen as the research object.They were divided into the observation group and the control group in accordance with the principle of randomization with 70 cases in each group.The control group was treated with conventional methods of nursing care of cardiology.The observation group was given with sleep- related nursing interventions on the basis of the routine care.The sleep quality score (PSQI)24 h and 1 week,2 weeks postoperation and treatment compliance 2 weeks postoperation were compared between the two groups. ResultsThe study showed that the PSQI score 24h postoperation showed no significant difference,but 1 week and 2 weeks after the operation,the score of the observation group was significantly lower than the control group.The full compliance rate in the observation group was significantly higher than the control group.The non-full compliance rate was significantly lower than the control group,the differences were statistically significantConclusionsNursing intervention can improve treatment compliance of patients,improve sleep quality of patients after cardiac intervention.It is conducive to the rehabilitation of patients and is worthy of clinical application.

Objective To explore the relationship between diethylhexylphthalate (DEHP) and peritoneal sclerosis and its possible mechanism. Methods Isolated human peritoneal mesothelial cells (HPMC) was cultured for five days in culture solution with varied doses of DEHP ７．７?of 10-6mol/L (A group), 5.4?１０－５mol/L (B group) and 2. 2?10-4 mol/L (C group) respectively. Culture solution without DEHP was as control. Total collagen synthesis and secretion was assayed by 3H-proline incorporation. ELISA method was used to detect the level of secreted fibronectin (FN) . The expression of FN mRNA , collagen ImRNA, collagen Ⅲ mRNA and TGF－?l mRNA was determined by RT-PCR. Results (1)HPMC expressed FN, laminin, collagen Ⅲ and TGF-?１. (2)DEHP stimulated FN and collagen expression with a higher level in C group compared with control(P

Objective To investigate the protective effects and mechanism of shenmai injection(SMI) on cardiomyocytes injured by hydrogen peroxide(H 2O 2) or angiotension Ⅱ(AngⅡ). Methods According to the different concentrations of H 2O 2, AngⅡ,SMI,Vitamin C(VitC) added into the cardiomyocytes culture media(CCM), the cultures were divided into 15 groups. Lactate dehydrogenase(LDH ),malondialdehyde(MDA),superoxide dismutase (SOD) of CCM and cardiomyocytes viability(CMV), Na +-K +-ATPase,Ca 2+-ATPase?cardiomyocytes apoptosis rate(CMAR) ,nitrogen oxide(NO), nitrogen oxide synthesis enzyme(NOS),eNOS expression of cardiomyocytes were detected respectively .Results H 2O 2 or AngⅡ could decrease CMV, SOD, Na +-K +-ATPase,Ca 2+-ATPase,NOS,NO,eNOS expression and increase CMAR,LDH and MDA.SMI could lessen the changes of the items mentioned above ,which were caused by H 2O 2 or AngⅡ.The effects of SMI 10 ml/L were stronger than those of SMI 5 ml/L or VitC 50 mg/L.Conclusion SMI has a significant protective effect on cardiomyocyte injured by H 2O 2 or AngⅡ.

Objective To explore the clinical characteristics and diagnosis of Epstein-Barr(EB) virus encephalitis(EBE) in children. Methods The verification of EBE was based on detection of EBV DNA in cerebrospinal fluid (CSF) by fluorogenic quantitative PCR(FQ-PCR) and Nest-PCR. The clinical and CSF changes of 27 EBE cases and 26 controls were analyzed and compared. Results EB-DNA in CSF by FQ-PCR of 13 cases of EBE was (2.82?2.03)?10 3copies.There was no significant difference in clinical manifestations between EBE and HSE groups, except that WBC in CSF of EBE was lower than those of HSE.Conclusions EBE is not infrequent, about 10 % of encephalitis in children. EBE is always present independently, which is not a complication of infectious mononucleosis(IM).Detection of EBV-DNA in CSF is a sensitive and specific test for diagnosing of EBE. Early treatment may be beneficial to the prognosis of EBE.

Objective To investigate the association of ret gene rearrangement mutation with the pathogenesis of papillary thyroid carcinoma (PTC). Methods Twenty-seven cases of PTC were analysed for expression of ret gene rearrangement (ret/PTCs) by multiplex-PCR at first, and then ret/PTC1-3 were identified by identification-PCR (ID-PCR). Finally, the specific ret/PTC was affirmed by automated direct sequencing. Ten specimens of malignant thyroid tissues of other histological types, 33 benign thyroid lesions and 30 normal thyroid specimens beside tumor (as the control) were also included. Results (1) Fifteen samples showed positive ret/PTCs, 11 of which harboured ret/PTC1,3 were positive for ret/PTC3, and 1 for ret/PTC2. All the rearrangements were clearly identified by automated direct sequencing of ID-PCR products. (2) All the 15 ret/PTC-positive tissue samples were histologically confirmed to be PTC. The prevalence of the tumor-specific ret rearrangements in 27 patients with PTC is 55.6% (15/27). (3) No significant difference was found regarding the gender and age of the patients, tumor size and metastasis of neck lymph node. 33.3% (2/6) of the PTC with invasion of extrathyroidal soft tissue were ret/PTC-positive, as compared with 66.7%(4/6) for ret/PTC-negative group (P

Objective To investigate the value of Cytochrome P450 (CYP3A5) * 3 gene polymorphism in providing individualized administration for the use of tacrolimus (Tac) in renal transplantation recipients.Method Pyrophosphate sequencing method was used to determine the CYP3A5 * 3 genotype of renal transplant patients in the first day after surgery.Sixty recipients were divided into experiment group and control group.Both groups of patients were routinely given the initial dose of Tac-4.0 mg/day in the first day after surgery.The experiment group of patients were given different doses of Tac based on the different CYP3A5 * 3 genotypes at the third day after surgery [for AA:0.12 mg/(kg· day),and for GG:0.06 mg/(kg· day)],and the control group of patients were given different dosages of Tac according to drug concentration.Different parameters were compared between two groups of patients:percentage of patients reaching the target concentration (3-8 μg/L) at the fifth day after surgery,days required to reach the target concentration level,times needed to adjust the dosage of Tac within two weeks.Result The percentage of patients reaching the target concentration in experiment group and control group was 90％ and 46.67％,respectively (P＜ 0.05).Days required to reach the target concentration were (3.67 ± 1.32) and (7.57 ± 3.42) on average,respectively (P ＜ 0.05).Times of adjusting the Tac dose in experiment group was significantly less than those in the control group (P＜0.05).In the experiment group,the target concentration was obtained even without dosage adjustment (70％).Conclusion Individualized adjustment of Tac doses for patients according to recipients' different CYP3A5 * 3 genotypes is beneficial for reaching target concentration as soon as possible,which is superior to traditional dosage regimen.

AIM:To investigate the relationship between autophagy and calcification in vascular smooth muscle cells ( VSMCs) after platelet-derived growth factor (PDGF)-BB stimulation.METHODS:Cultured VSMCs were stimulated with PDGF-BB for different time, the expression of vascular calcification-related proteins and autophagy-related proteins were detected by Western blot .The interaction be-tween Beclin1 and PI3KC3 was detected by co-immunoprecipitation.RESULTS: The expression of BMP2 and ALP showed a trend from decline to rise.ALP slumped at 12 h, and BMP2 slumped at 6 h.Moreover, the expression of Beclin-1 showed a trend from rise
to decline, and peaked at 12 h.The conversion of LC3-ⅠtoⅡincreased in a time-dependent manner , and peaked at 24 h.The ex-pression of BMP2 and ALP was increased in VSMCs incubated with PDGF-BB and autophagy inhibitor 3-MA, compared with PDGF-BB-stimulated VSMCs.Furthermore, the interaction between Beclin1 and PI3KC3 was enhanced at 6 h after PDGF-BB stimulated, peaked at 12 h, and kept in high level at 24 h.Moreover, the phosphorylation level of Beclin 1 was enhanced by PDGF-BB stimulation, and peaked at 6 h.CONCLUSION:Our findings demonstrate that PDGF-BB-induced autophagy inhibits VSMC calcification by en-hancing Beclin1 phosphorylation and interaction between Beclin 1 and PI3KC3.
