The thres holds of detectability and identification threshold were related to MMSE in AD group (r =-0.50,-0.54, P< 0.01). Conclusion The early diagnostic value of olfactory function measurement to AD is very great.

Objective To investigate the expressions of Pokemon and c-myc in colorectal cancer,colorectal adenomas and normal colorectal mucosa tissues,and demonstrate its relationship with clinicopathological features and prognosis in patients with colorectal cancer.Methods The specimens were taken from colorectal cancer tissue of 86 patients,colorectal adenomas tissue of 60 patients,and 40 normal colorectal mucosa tissue.The expressions of Pokemon and c-myc protein were detected by immunohistochemistry,and the expressions of Pokemon and c-myc gene were detected by reverse transcription polymerase chain reaction (RT-PCR).The correlation between the expressions of Pokemon and c-myc,and clinicopathological features was analyzed.Results The positive expression rates of Pokemon and c-myc protein in colorectal cancer tissue were significantly higher than those in colorectal adenomas tissue and normal colorectal mucosa tissue:69.8％ (60/86) vs.13.3％ (8/60) and 5.0％ (2/40),73.3％ (63/86) vs.15.0％ (9/60) and 2.5％(1/40),and the expression levels of Pokemon and c-myc gene in colorectal cancer tissue were significantly higher than those in colorectal adenomas tissue and normal colorectal mucosa tissue:0.915 ±0.247 vs.0.358 ±0.102 and 0.277 ±0.085,1.272 ±0.360 vs.0.398 ± 0.153 and 0.255 ±0.097,there were statistical differences (P ＜ 0.05).The expression levels of Pokemon and c-myc gene in colorectal cancer tissue had a close correlation with the degree of infiltration,histological differentiation,lymph node metastasis,distant metastasis and Dukes stage,there were statistical differences (P ＜ 0.05),but had no correlation with the sex,age,and tumor diameter (P ＞ 0.05).Conclusions The expression levels of Pokemon and c-myc are higher in colorectal cancer tissue,and the expressions are related to the clinicopathological features of colorectal cancer.The expression levels of Pokemon and c-myc may predict the prognosis in patients with colorectal cancer.

OBJECTIVE: To explore the immunological mechanism of exfoliative tongue fur in children with asthma. METHODS: Thirty-nine children with asthma, twenty-eight children with repetitive respiratory tract infection (non-asthma) and eleven healthy children were divided into five groups, which were asthma with exfoliative fur or with non-exfoliative fur groups, non-asthma with exfoliative fur or with non-exfoliative fur groups and normal control group. The concentrations of keratin 13 and bcl-2 in cells exfoliated from tongue fur were detected by immunohistochemical method. The expression levels of blood cell chemokine receptor-3 (CCR-3) and CD4(+) were examined by flow cytometry, and the levels of serum cortisol and IgE were detected by radioimmunoassay. RESULTS: The levels of blood CD4(+) and CCR-3 of children with asthma and exfoliative fur were higher than those in the asthma with non-exfoliative fur group and the normal control group (P<0.05). The serum level of cortisol in the groups of asthma with exfoliative fur and non-asthma with exfoliative fur were lower than that in the other groups (P<0.05). The serum levels of IgE in asthma with exfoliative fur or with non-exfoliative fur groups were higher than that in the other groups (P<0.05). Concentrations of keratin 13 in the cells exfoliated from tongue fur in the groups of asthma or non-asthma with exfoliative fur were lower than that of the other groups (P<0.05). There was no significant difference of expression level of bcl-2 in the cells exfoliated from tongue fur among these five groups. CONCLUSION: There is a reasonably close relationship between the formation of exfoliative tongue fur and the immune system such as low level of serum cortisol and high levels of blood CD4(+) and CCR-3, which may all promote the formation of exfoliative fur. The disability of keratinization and apoptosis of epithelial cells of tongue may also be one cause for its formation.

Objective To use Q value method to assess the effect of combination therapy with vitamin E and vitamin C for idiopathic asthenospermia. Methods 76 patients diagnosed as idiopathic asthenospermia by computer-assisted semen analysis according to the WHO criteria were selected at the andrology clinic from August 2012 to November 2013. Malondialdehyde (MDA) concentration was measured by using thiobarbituric acid (TBA) assay. The patients were randomly divided into three groups. Vit C group received vitamin C 200 mg thrice daily, vit E group received vitamin E 100 mg thrice daily , and the combination group received vitamins E and C for 12 weeks. Repeat semen analysis and MDA measurement were conducted after treatment, and the Q value which evaluated whether a synergistic interaction existed was calculated. Results MDA concentration decreased in all the groups, with the lowest concentration in the combination group. While all the groups achieved improvement in term of progressive motility , with the combination group presented far more better than the other two groups , exhibiting a synergistic interaction, with a Q value of 1.18. Conclusion Combination therapy with vitamin E and vitamin C has a marked internal synergistic effect on antioxidation in the treatment of idiopathic asthenospermia.

Objective To investigate the clinical efficacy and safety of dexmedetomidine combined with sevoflurane in elderly patient undergoing percutaneous nephrolithotomy.Methods Forty ASA Ⅰ ～ Ⅱ elderly patients of both sexes,aged 65 ～ 76 (71.0 ± 6.0)yr,scheduled for elective surgery of percutaneous nephrolithotomy under general anesthesia,were randomly divided into two groups (n =20 each):dexmedetomidine/sevoflurane group (group D) and propofol/sevoflurane group (group P).All patients received fentanyl,propofol,and cisatracurium for anesthesia induction.After endotracheal intubation,patients in group D received an initial loading dose of 0.5 μg/kg (4 μg/ml) of dexmedetomidine over 10 min,followed by a continuous infusion of 0.3 ～ 0.6 μg/(kg · h).Patients in group P received an initial loading dose of 1 mg/kg of propofol over 10 min,followed by a continuous infusion of 3 ～ 6 mg/(kg · h).All patients received the inhalation of sevoflurane for maintenance.Bispectral index was used to maintain a similar level of hypnosis in both groups (40 ～ 60).The heart rate (HR),blood pressure (BP) [systolic blood pressure (SBP)/diastolic blood pressure (DBP)],oxygen saturation (SpO2),end-tidal carbon dioxide partial pressure (PETCO2) at different time points before anesthesia (T0),10 min after prone position (T1),30 and 60 min started lithotripsy (T2-3),and at the end of operation (T4) were recorded,respectively.The operation time,amount of blood loss,and volume of fluid infusion were recorded.Recovery time of spontaneous ventilation,awaking time (open eyes by calling),extubation time,staying time at postanesthesia care unit (PACU),and relevant complications were also recorded.Results Compared to the baseline value at T0,SBP and DBP were significantly decreased at T1 in both groups(P ＜0.05),and no significant differences in the SBP,DBP,SpO2,and PETCO2 were found between two groups(P ＞ 0.05).Compared to the baseline value at T0,the HR was significantly decreased at T1 ～ T4 in group D (P ＜ 0.05),the HR was significantly lower at T1 ～ T4 in group D than that of group P (P ＜ 0.05).No significant differences in operation time,amount of blood loss,and volume of fluid infusion were found between two groups (P ＞ 0.05).No significant differences in recovery time of spontaneous ventilation,staying time at PACU,nausea,vomit,and agitation were found between two groups (P ＞ 0.05),while awaking time and extubation time were significantly longer in group D than that of group P(P ＜ 0.05).The shivering was significantly less in group D than that of group P (P ＜ 0.05).Conclusions Both dexmedetomidine/sevoflurane and propofol/sevoflurane anesthesia are suitable for elderly patients undergoing percutaneous nephrolithotomy.Dexmedetomidine/sevoflurane makes time of awake and extubation longer,but dexmedetomidine can reduce the shivering and the attendant complications caused by shivering.

Objective To investigate the infection status quo and genotype distribution of human papillomavirus(HPV) infection situation among females in west Guangxi area.Methods Cervical exfoliative cells samples from 3 315 women were collected to detect HPV genotyping with Cape flow-through hybridization.Then the results were statistically analyzed.Results The overall HPV infection rate was 21.30%(706/3 315),in the females of HPV positive infection,the high-risk type infection was predominant,accounting for 89.52%(632/706).The HPV infection type was dominated by single type infection,accounting for 72.66% the double infection accounted for 22.10%(156/706). The 21 HPV subtypes were detected.The high-risk HPV subtypes with high detection rate were HPV52(26.77%),HPV16(15.30%) and HPV58(15.01%).The low-risk HPV subtypes with high detection rate were HPV CP8304(11.90%) and HPV6(3.68%).The HPV subtypes were distributed differently at different ages.In 7 age groups of≤20,>20-30,>30-40,>40-50,>50-60,>60-70,>70 years old,the infection rates of high risk HPV were 21.62%(8/37), 19.26%(120/623),17.66%(220/1 246), 14.88%(153/1 028), 16.83%(51/303),15.52%(9/58) and 30.00%(6/20) respectively,showing no statistically significant differences among them(χ2=10.019,P=0.124).Conclusion Cervical HPV infection are mainly high-risk HPV subtypes and single type infection in females of western Guangxi area.The HPV subtypes with high infection rate are 52,16,58 and CP8304.

Purpose: Ischemic brain injury results in high mortality and serious neurologic morbidity. Here, we explored the role of SNHG15 in modulating neuronal damage and microglial inflammation after ischemia stroke. Materials and Methods: The hypoxia/ischemia models were induced by middle cerebral artery occlusion in mice and oxygenglucose deprivation/reoxygenation (OGD/R) in vitro. Quantitative real-time PCR (qRT-PCR) and Western blot were conducted to determine the levels of SNHG15, miR-302a-3p, and STAT1/NF-κB. Moreover, gain- or loss-of functional assays of SNHG15 and miR-302a-3p were conducted. MTT assay was used to evaluate the viability of HT22 cells, and the apoptotic level was determined by flow cytometry. Furthermore, enzyme-linked immunosorbent assay was performed to detect oxidative stress and inflammatory mediators in the ischemia cortex and OGD/R-treated BV2 microglia. Results: The SNHG15 and STAT1/NF-κB pathways were both distinctly up-regulated, while miR-302a-3p was notably down-regulated in the ischemia cortex. Additionally, overexpressing SNHG15 dramatically enhanced OGD/R-mediated neuronal apoptosis as well as the expression of oxidative stress and inflammation factors from microglia. In contrast, knocking down SNHG15 or overexpressing miR-302a-3p relieved OGD/R-mediated neuronal apoptosis and microglial activation. Moreover, the rescue experiment testified that overexpressing miR-302a-3p also attenuated SNHG15 up-regulation-induced effects. In terms of the mechanisms, SNHG15 sponged miR-302a-3p and activated STAT1/NF-κB as a competitive endogenous RNA, while miR-302a-3p targeted STAT1 and negatively regulated the STAT1/NF-κB pathway. Conclusion SNHG15 was up-regulated in the hypoxia/ischemia mouse or cell model. The inhibition of SNHG15 ameliorates ischemia/hypoxia-induced neuronal damage and microglial inflammation by regulating the miR-302a-3p/STAT1/NF-κB pathway.
