Objective To explore the role of 14-3-3σ in cell cycle arrest,proliferation inhibition of HaCaT cells after UVB exposure.Methods Crystal violet assay was used to determine the viable density of HaCaT,HaCaTKD cells after being irradiated with UVB of different doses (10,20,30,40,50,60 and 80 mJ/cm2) for 48 h.After HaCaT and HaCaTKD being treated with 30 mJ/cm2irradiation,cell growth and cell cycle distribution were detected by CCK-8 assay and PI staining combined with flow cytometry,respectively.Western blot was used to evaluate the protein expression of 14-3-3σ,Cdc2,Cdc25c and Cyclin B1.Results After 48 h,the survival rate of both HaCaT and HaCaTKD decreased in a dosedependent manner.Especially,HaCaTKD cells had drastically low proliferation rate compared with normal HaCaT at 10 mJ/cm2 (t =8.83-49.63,P ＜ 0.05).The proliferation rate of HaCaTKD cells was significantly lower than that of HaCaT cells (F =32.89,P ＜ 0.05).After treatment with 30 mJ/cm2 UV irradiation,the ability of proliferation in normal HaCaT cells was recovered after 24 h while there was no proliferation in HaCaTKD cells within 72 h after the same treatment.The distribution of cell cycle has little change in HaCaTKD (P ＞ 0.05).UVB treatment led to cell cycle arrest from 6 to 18 h in HaCaT cells(t =7.41,9.22,9.16,P ＜0.05)while no cell cycle arrest could be observed in the HaCaTKID cell.Western blot detection indicated that the expression of 14-3-3σ in HaCaT cells was upregulated(t =5.42-9.57,P ＜0.05)while the Cdc25c and Cyclin B1 proteins were downregulated in both HaCaT and HaCaTKD cells (t =3.95-11.21,P ＜0.05).Specifically,Cdc2 protein decreased in HaCaT cells(t =4.93-5.37,P ＜ 0.05)but there was no change in HaCaT~ cells.Conclusions 14-3-3σ protein affects the proliferation and cell cycle of HaCaT cells after UVB irradiation.14-3-3oσ co-activates the expression of Cdc2,Cdc25cand Cyclin B1 to mediate UVB-induced G2/M arrest in HaCaT cells.

Objective To investigate the effects of sevoflurane on inhibition of growth of human lung adenocarcinoma A549 cells by cisplatin and γ ray.Methods The human lung adenocarcinoma cell line A549 was seeded in culture plate.After being cultured for 24 h,the cells were randomly divided into 6 groups (n =6each):control group (group C),sevoflurane group (group S),cisplatin group (group D),cisplatin + sevoflurane group (group DS),γ ray group (group R) and γ ray + sevoflurane group (group RS).A549 cells were exposed to 2.5% sevoflurane for 4 h in group S.Cisplatin with the final concentration of 3 mg/L was added to the culture medium and the cells were then incubated for 4 h in group D.Cisplatin with the final concentration of 3 mg/L was added to the culture medium and the cells were then exposed to 2.5 % sevoflurane for 4 h in group DS.A549 cells were exposed to γ irradiation (2 Gy) for 4 h in group R.A549 cells were exposed to γ irradiation (2Gy) and to 2.5% sevoflurane for 4 h in group RS.The cells were cultured for another 24 h after the end of treatment,the colony formation was detected and the rate of colony formation was calculated by colony formation assay.Proliferation of A549 cells was measured by plate colony formation and MTF assay and the rate of proliferation inhibition was calculated.Cell apoptosis was detected with flow cytometer.The expression of X-linked inhibitor of apoptosis protein (XIAP) and caspase-3 was detected by Western blot.Results Compared with group C,the rate of colony formation was significantly decreased,the rate of proliferation inhibition and percentage of apoptotic cells were increased,XIAP expression was down-regulated and caspase-3 expression was up-regulated in groups S,D,DS,R and RS (P ＜ 0.05).The rate of colony formation was significantly lower,the rate of proliferation inhibition and percentage of apoptotic cells were higher,XIAP expression was lower and caspase-3 expression was higher in group DS than in groups S and D,and in group RS than in groups S and R (P ＜ 0.05).Conclusion Sevoflurane can enhance cisplatin and γ ray-induced inhibition of growth of human lung adenocarcinoma A549 cells,and downregulation of XIAP expression and up-regulation of caspase-3 expression may be involved in the mechanism.

Objective To know the medication compliance in elderly patients with hypertension,to analyze the influence factors of medication compliance,and to propose forward intervention countermeasures.Methods The treatment of hypertension in elderly patients was investigated by questionnaire survey.Medication compliance and influence factors were analyzed.Results 166 cases with poor medication compliance,and the rate was 45.0％; 203 cases with good medication compliance,and the rate was 55.0％.It's showed significantly difference on degree of education between the observation group and control group (x2 =12.071,P=0.002).The proportion of peasant and worker was higher in the observation group than control group (78.9％ vs.62.1％,x2 =12.817,P=0.002).The smoker (48.8％) and drinker (59.0％) in observation group more than smoker (27.1％) and drinker (31.0％) in control group(x2=18.481,P＜0.001; x2=29.115,P＜ 0.001).The ratio of payout of-pocket for healthcare was higher in the observation group (21.1％) than control group (9.9％) (x2=9.084,P=0.003).The duration of hypertension was longer in the observation group (8.8±4.6) than control group (6.0±4.1) (t=1.806,P=0.036).The income per month was less in the observation group (1850±150) than control group (2150±200) (t=5.799,P＜ 0.001).There were regression relationship between medication compliance and degree of education,medical security and duration of hypertension.Conclusions According to the influence factors of medication compliance in elderly hypertensive patients,it's useful to improve medication compliance by enhancing health education and designing a personal treatment.

Objective To investigate the effects of sevoflurane and propofol on postoperative cognitive function after abdominal surgery for elderly patients with diabetes. Methods Seventy diabetic patients (aged 60~75 yr, ASAⅠorⅡ) underwent abdominal surgery and are included in the research. Diabetic patients were randomly divided into two groups (n=35): sevoflurane group(group DS) and propofol group (group DP). MMSE score, the attachment test, words memory test and Stroop color word test were carried and the results were recorded before operation (T1), postoperative 24 h (T2), 48 h (T3) and 1 w (T4). Results Compared with T1, patients′ MMSE score reduced at T2 and T3. Time spent in attachment test is longer at T2 and T3. Mistaken incidences in Stroop color words test 1, 2 and 3 are higher and time longer at T2. Time spent on Stroop color words test 2 and 3 is longer in T3. Words memory test reveals decline at T2 and T3, whose difference is statistically significant (P < 0.05). Cognitive dysfunction incidence in the two groups shows no statistical significance (P > 0.05). Conclusion Sevoflurane and propofol can result in postoperative cognitive dysfunction for elderly patients with diabetes within 48 h after abdominal surgery, there were no difference between the effects of them.

Objective To investigate the oropharyngeal microbial colonization in elderly patients.Methods Totally 618 elderly cases and 96 young and middle-aged cases were involved in this investigation.The colonization of bacteria and fungi on the oropharyngeal mucosa were obtained by throat swab cultures.Results There were 85.4％ of cases (82 cases) with Streptococcus viridans and Neisseria gonorrheae on the oropharynx mucosa in young and middle-aged group and the pattern of constitute was simple.3 to 5 bacterial species were isolated from the oropharyngeal mucosa in elderly group.There were only 25.7％ of cases (159 cases)with Streptococcus viridans and Neisseria gonorrheae on the oropharyngeal mucosa in elderly group.Biodiversity of the constitution pattern in the bacterial colonization was exhibited in the elderly.The colonization rate of Gramnegative bacilli was higher in elderly group than in young and middle-aged group [53.1％ (328/618)vs.6.3％ (6/96)].Staphylococcus aureus and Streptococcus pneumonia were the common Grampositive bacteria colonization in the elderly.The colonization rate of Candida fungus was 9.1 ％ (56/618) in the elderly.Conclusions The reduction of commensal bacteria,especially Streptococcus viridans may be the pathological basis of mode changes in bacteria colonization and opportunistic bacteria colonization on oropharyngeal mucosa in the elderly.The colonization rate of oropharyngeal Gram-negative bacili is obviously increased and Klebsiella Pneumoniae is the common bacteria on oropharyngeal mucosa in the elderly.Enterobacteriaceae,Pseudomonas aeruginosa and Acinetobacter baumannii are sensitive to common antibiotics.

Objective To analyze the correlation between clinical features and renal dysfunction in patients of acute lacunar infarction with progressive cerebral microbleeds (CMBs). Methods Two hundred and sixty-five patients with first-episode acute lacunar infarction were selected. The serum creatinine was measured within 24 h of admission and the estimated glomerular filtration rate (eGFR) was calculated. The brain MRI (including gradient-echo images) was examined within 2 d of admission and after 1 years of follow-up, respectively. The progressive CMBs was assessed with microbleeds anatomical rating scale (MARS), and the patients were divided into progressive CMBs group (progressive group, 42 cases) and non progressive CMBs group (non progressive group, 223 cases). The clinical features of 2 groups were compared and the correlation between progressive CMBs and renal dysfunction was analyzed. Results The age, 24 h pulse pressure, incidences of renal dysfunction and CMBs in progressive group were significantly higher than those in non progressive group: (69.8 ± 5.8) years vs. (61.5 ± 4.9) years, (63.3 ± 3.1) mmHg (1 mmHg=0.133 kPa) vs. (51.8 ± 4.2) mmHg, 69.0％(29/42) vs. 39.9％(89/223) and 57.1％(24/42) vs. 25.1％(56/223), and the platelet was significantly lower than that in non-progression group:(168 ± 35) ×109/L vs. (189 ± 40) ×109/L, and there were statistical differences (P<0.05 or<0.01). The Logistic regression analysis result showed that renal dysfunction and CMBs were Independent risk factors of progressive CMBs (OR = 1.571 and 1.054, 95％ CI 1.042 - 2.493 and 1.010 - 1.142, P<0.05). Conclusions The rate of renal dysfunction is higher in patients of acute lacunar infarction with progressive CMBs, and progressive CMBs are associated with renal dysfunction.

Objective To evaluate the effect of oxycodone on migration of human colon cancer cells and the role of μ and κ receptors.Methods The human colon cancer HCT116 cells at the logarithmic growth phase were seeded in 24-well or in 6-well plates at a density of 1 × 106 cells/mnl (0.5 ml/well or 2 ml/well,144 wells in total).The cells were divided into 6 groups (n=24 each) using a random number table:control group (group C),1,5 and 10 μmol/L oxycodone groups (group O1,group O2 and group O3),oxycodone plus μ receptor antagonist CTOP group (group O2+CTOP) and oxycodone plus κ receptor antagonist nor-binaltorphimine group (group O2+BNI).The cells were incubated for 24 h with oxycodone 1,5 and 10 μmol/L in O1,O2 and O3 groups,respectively.The cells were incubated for 24 h with 5 μmol/L oxycodone plus 20 μmol/L CTOP and 5 μmol/L oxycodone plus nor-binahorphimin 20 μmol/L in O2+CTOP and O2+BNI groups,respectively.The invaded and migrated cells were counted,and the levels of Ras homolog gene family member A (RhoA),Rho-associated protein kinase 1 (ROCK1),matrix metalloproteinase-2 (MMP-2) and MMP-9 were detected.Results Compared with group C,the number of invaded and migrated cells was gradually decreased,and the levels of RhoA,ROCK1,MMP-2 and MMP9 were gradually decreased in O1,O2 and O3 groups (P＜0.05),and no significant change was found in the parameters mentioned above in group O2+BNI (P＞0.05).Compared with group O2,the number of invaded and migrated cells was significantly increased,and the levels of RhoA,ROCK1,MMP-2 and MMP9 were increased in group O2 + BNI (P＜0.05),and no significant change was found in the parameters mentioned above in group O2+CTOP (P＞0.05).Conclusion Oxyc odone can inhibit the migration of human colon cancer cells,and the mechanism is totally related to inhibition of RhoA/ROCKl signaling pathway activation after activating κ receptors,but not related to μ receptors.

Objective To evaluate the effects of sufentanil and morphine on cisplatin-induced acute kidney injury in rats.Methods Thirty-two healthy Sprague-Dawley rats, aged 8-10 weeks, weighing 220-280 g, were randomly divided into 4 groups (n =8 each) using a random number table: control group (group C);cisplatin group (group Cis);sufentanil group (group S);morphine group (group M).Cisplatin 16 mg/kg was injected intraperitoneally in group Cis.In group S, cisplatin 16 mg/kg was injected intraperitoneally, followed by injection of sufentanil 2 μg/kg over 5 min via the caudal vein for 3 consecutive days.In group M, cisplatin 16 mg/kg was injected intraperitoneally, followed by injection of morphine 2 μg/kg over 5 min via the caudal vein for 3 consecutive days.The equal volume of normal saline was given in group C.After the end of administration on 3rd day, blood samples were collected from the orbital venous plexus for measurement of serum blood urea nitrogen (BUN) and creatinine (Cr) concentrations.The animals were then sacrificed, and the left kidney specimens were obtained for examination of the pathological changes (under the light microscope) and for determination of the tumor necrosis factor-alpha (TNF-α) , interleukin-1 beta (IL-1β) and interleukin-6 (IL-6) concentrations (by enzyme-linked immunosorbent assay) , and expression of X-linked inhibitor of apoptosis protein (XIAP) , suvivin and caspase-3 (by Western blot).Periodic acid-Schiff's staining was used to evaluate the pathological changes of the renal tubule.Results Compared with group C, the serum BUN, Cr concentrations and renal tubule injury score were significantly increased, the contents of TNF-α, IL-1β and IL-6 were increased, the expression of XIAP and suvivin was down-regulated, and the expression of caspase-3 was up-regulated in Cis,S and M groups (P＜0.05).Compared with group Cis, the serum BUN and Cr concentrations and renal tubule injury score were significantly decreased, the contents of TNF-α, IL-1β and IL-6 were decreased, the expression of XIAP and suvivin was up-regulated, and the expression of caspase-3 was down-regulated in S and M groups (P＜0.05).There were no significant differences in the indexes mentioned above between group S and group M (P＞0.05).Conclusion Both sufentanil and morphine can reduce cisplatin-induced acute kidney injury in rats with similar efficacy, and the mechanism may be related to the inhibition of the inflammatory responses and cell apoptosis.

OBJECTIVE To investigate the significance of CNS in clinical infections.METHODS A total of 114 CNS strains isolated from our hospital were identified by conventional procedures and the icaD gene was amplified by PCR.RESULTS Of all CNS strains,the highest isolated rate was S.epidermidis(41.2%).CNS isolated from deep venous catheters,wound secretions and blood had a higher rate of carrying ica operon,accounted for 44.4%,42.1% and 36.8%,respectively,whereas 24.0% in respiratory secretions and 14.1% in urine.Among the ica operon positive CNS strains,the percentages of S.epidermidis and S.haemolyticus were 42.6% and 19.0%.CONCLUSIONS There is a wide range of CNS species carrying ica operon,especially in S.epidermidis.CNS isolated from different specimens might have different significances.It should be cautious to assess the results of isolated CNS from respiratory and urine specimens.The CNS isolates from blood specimens might be contaminated.The PCR method for the ica operon is simple and easy.
