Objective To investigate the effects of sub-chronic exposure of nickel oxide nanoparticles （Nano NiO） on endocrine function of male SD rats，and to analyze the toxicity and mechanism of Nano NiO on testicular cells. Methods The specific pathogens free male SD rats were randomly divided into five groups with ten rats in each group. Rats in low-，medium and high-dose groups were given Nano NiO suspension with the mass concentration of 0.16，0.80 and 4.00 g/L，respectively； rats in blank control group were given equal volume of 0.9% sodium chloride solution；rats in positive control group were given micron nickel oxide suspension with the mass concentration of 4.00 g/L. Drip every three days for nine weeks. After the Nano NiO exposure，atomic fluorescence spectrometry was used to determine the levels of nickel in the blood and testicular tissue. The enzyme-linked immunosorbent assay was used to detect serum level of sex hormone. The ploidy ratio，cell cycle and apoptosis rate of testicular cells were analyzed by flow cytometry. Western blotting was used to detect the relative expression of apoptosis related proteins in the testis. Results The level of nickel in blood and testicular tissue of rats in positive control group and the three doses groups were higher than that of blank control group（all P<0.05）. The level of nickel in blood and testicular tissue of rats in the medium-dose and high-dose groups were higher than that in the positive control group（all P<0.05）. There was a positive correlation between the level of nickel in blood and testicular tissue（P<0.01）. The serum levels of testosterone，follicle stimulating hormone（FSH）and luteinizing hormone（LH）in the medium- and high- dose groups were lower than that in blank control group（all P<0.05）. However，there was no significant difference in serum gonadotropin-releasing hormone among all groups（P>0.05）. Compared with the blank control group，the proportion of haploid and diploid cells and the ratio of cells in G0/ G1 and S phase decreased in the medium- and high-dose groups（all P<0.05），the tetraploid cell ratio，G2/M cell ratio and early apoptotic rate of testicular cells increased（all P<0.05）. Compared with the blank control group，the relative expression of B-cell lymphoma-2（BCL-2）protein and the ratio of BCL-2/BCL-2-related X protein（BAX）in testicular cells of rats decreased in the medium- and high-dose groups（all P<0.05），the relative expression of BAX and caspase-3 protein were increased（all P< 0.05）. Compared with the positive control group，the level of nickel in blood and testicular tissue of rats was increased in the high-dose group（all P<0.05），the ratio of haploid cells and the ratio of testicular cells at G0/G1，S phase and BCL-2 /BAX ratio in testicular tissue decreased（all P<0.05），the tetraploid ratio，G2/M phase ratio，early apoptotic rate and total apoptotic rate of testicular cells increased（all P<0.05）. Conclusion Exposure to Nano NiO could inhibit the secretion of FSH，LH and testosterone in male rats. Nano NiO can cross the blood-testosterone barrier，interfere with the proliferation of testicular cells， induce apoptosis of testicular cells through the mitochondrial apoptosis pathway，inhibit the formation of haploid sperm cells， resulting in disorders of spermatogenesis.

Objective To compare the effects of adjustable pressure drainage device, negative pressure ball drainage and drainage bag drainage on patients with the total hip arthroplasty. Methods The silicone drainage ball with negative pressure, the urine collection bag, the infusion set′s regulator were used to make adjustable pressure drainage device. 120 cases of total hip arthroplasties from January to December in 2015 were chosed and divided randomly into 3 groups based on the sequence of operation notifications. In 40 cases, drainage bag were used (control group 1), 40 cases with negative pressure ball drainage (control group 2) and 40 cases with adjustable pressure drainage device (experimental group). Total postoperative bleeding, the blood transfusion amount, swelling (the thickness of hematoma) and the nursing workload of the three groups were compared. Results The total postoperative bleeding, the blood transfusion amount, the thickness of hematoma and the nursing workload in the experimental group were (775.1±130.5) ml, (3.5±1.3) mm, (180.2±29.9) ml, (34.5±5.2) min. The total postoperative bleeding, the blood transfusion amount, the thickness of hematoma and the nursing workload in the control group 1 were (889.4 ± 160.8) ml, (5.2 ± 1.1) mm, (285.9 ± 30.4) ml, (40.6 ± 7.4) min and in the control group 2 were (876.2±156.7) ml, (4.3±1.2) mm,(208.3±33.3) ml, (50.3±8.5) min. Compared the data of the experimental group and the control group 1, the difference was of statistically significance (t=3.49-15.68, P < 0.01). Compared the data of the experimental group and the control group 2, the difference was of statistically significance (t=2.86-10.03, P<0.01). Conclusions The effects of adjustable pressure drainage device are better than the drainage bag and negative pressure drainage ball. It can effectively reduce the postoperative bleeding and the swelling degree, and bring a lot of relief to the patients and lots of convenience to the nursing work. The method is affordable, reliable and safe which should be promoted in the primary hospital.

Objective The aim of this study was to investigate the relationship between serum C-reactive protein (CRP) and muscle strength, physical performance in the elderly. Methods A cross-sectional study was conducted in Hangu district of Tianjin from April to June in 2013. Totally 1 131 subjects aged 60 years or older completed the survey. Every subject filled out a standard questionnaire and underwent grip strength test, timed up and go test (TUGT). Serum CRP concentrations were determined using chemiluminescent immunoassay kits. Multivariate analysis was performed to determine the relationship between CRP and muscle strength, physical performance. Results After adjustment for potential confounding factors including age, BMI, smoking status, drinking status, hypertension, diabetes, cardiovascular disease, anemia, cancer and physical activity, the multiple linear regression analysis suggested that CRP levels were inversely related to handgrip strength (β'=-0.11, P<0.01), and the logistic regression analysis showed that compared with subjects in the lowest quintile, the odds ratios and 95%confidence interval of higher quintile of CRP were 1.09 (0.50, 2.39) and 2.70 (1.34, 5.66) (Ptrend<0.05) in males. However, the relationship between CRP and muscle strength, physical performance was not statistically significant in females. Conclusions In males, higher serum CRP levels were independently correlated with lower muscle strength and poor physical performance in older adults. These results suggested that inflammation-signaling pathways may play an important role in the progression of sarcopenia.

ObjectiveTo investigate the prognostic factors of non-small cell lung cancer (NSCLC) after resection.MethodsClinical data of 131 NSCLC patients who underwent resection were reviewed and divided into chemotherapy group(86 cases) and non-chemotherapy group(45 cases) according to the treatment method.Survival rate was calculated by Kaplan-Meier method.The prognosis was analyzed by Cox proportional hazards model.ResultsThe median survival time (MST) of squamous cell carcinoma (76 cases),bronchial alveolar cell carcinoma( 8 cases),adenocarcinoma( 35 cases ),adenosquamous carcinoma (12 cases) was 60,54,34,24 months respectively (P＜0.05).For the patients of stage Ⅰ B,the MST of chemotherapy group and non-chemotherapy group was 75 and 76 months respectively(P ＞ 0.05 ).Multivariate analysis showed that tumor size,T stage,N stage,chemotherapy were independent prognostic factors (P =0.080,0.002,0.000,0.029).Conclusions Squamous cell carcinoma and bronchial alveolar cell carcinoma have better prognosis than adenocarcinoma,adenosquamous carcinoma.For the patients of stage Ⅰ B,the survival time can't be prolonged through platinum-based chemotherapy.Tumor size,T stage,N stage,chemotherapy are independent prognostic factors.

Objective To analyze the abnormal region of gray matter and its distribution characteristics in Parkinson's disease (PD) patients with mild cognitive impairment (PD-MCI),and to investigate the structural brain changes which closely related to mild cognitive impairment.Methods 27 PD patients were examined by T1WI three-dimensional brain volume (3D-fast spoiled gradient echo,3D-FSPGR) sequence,and were divided into 2 groups:PD patients with mild cognitive impairment group (PD-MCI group,n＝15) and PD patients without mild cognitive impairment (PD-nMCI group,n=12).Gray matter map in the two groups were analyzed by using voxel based morphometry (VBM) based on SPM5.Results There were significant differences in MMSE and MoCA scores between the two groups (P＜0.01 or 0.05).Compared with PD-nMCI group,gray matter volumes in PD-MCI group were decreased in bilateral mid frontal gyrus,left precentral gyrus,right mid-temporal gyrus,left superior temporal gyrus,transverse temporal gyrus,bilateral lingual gyrus,right cuneus,bilateral insular and right posterior cingutate gyrus.Conclusions Gray matter atrophy in bilateral mid-frontal gyrus,insular and left precentral gyrus is closely related to the mild cognitive impairment in PD patients.

Objective To investigate the photochemotherapeutic effect and the main affecting factors of PSD-007 on human cervical cancer Hela in vitro.Methods Hela cells were treated with different concentrations of PSD-007 (0,3.125,6.25,12.5,25,50,100 μg/ml) for 2 h under the influence of low-level laser (635 nm) therapy at different doses (0,0.6,1.2,2.4,4.8,9.6 J/cm2).Then the OD values and survival rates of Hela cells were measured by MTT assay compared with breast cancer cells MCF-7 in same treatment.Hela cells were treated with 12.5 μg/ml of PSD-007 for 2 h and were treated with different intensities of laser (1.2,2.4,4.8 J/cm2).The cellular apoptosis rate and cell cycle phase distribution of Hela were measured by a flow cytometry (FCM).Results Survival rates of Hela cells declined with more than 25 μg/ml of PSD-007 only,and significant difference in the inhibitory between the PDT group and control group was observed (P＜0.05).The survival rates of Hela after PDT was decreased by the concentration of sensitizer and dose of laser.There were no significant differences of cell survival rates among the groups with concentrations more than 12.5 μg/ml and laser energy density more than 4.8 J/cm2.The FCM assay showed a G0/G1 cell cycle arrest in a time-dependent manner.Conclusions PSD-007 has a photodynamic effect on Hela in vitro.Photodynamic effect of PSD-007 was more significant in Hela than MCF-7.Less photosensitizer and laser energy density were needed.

Objective To investigate subtle structural changes of white matter in patients with amnestic mild cognitive impair-ment (aMCI)using a tractography-based method.Methods Thirty patients with clinical diagnosis of aMCI and thirty-one cases of normal control(NC)and undergone diffusion tensor imaging.Cingulum (CG),corpus callosum (CC),uncinate fasciculus (UNC) and inferior occipitofrontal fasciculus (IOFF)were reconstructed,and fractional anisotrophy (FA)values were measured along these tracts using dTV II software.Differences of white matter tracts’FA values were explored between aMCI group and NC group.In addition,correlation analyses were also done between FA values and the MMSE(mini-mental state examination)scores in the aMCI patients.Results ① aMCI patients exhibited significant lower FA values in the bilateral CG,bilateral UNC and CC than NC group. Although there were no statistically significant differences,aMCI patients exhibited lower FA values than NC group in the left IOFF.② The FA values of right CG were positively correlated with MMSE scores.Conclusion Abnormal changes of FA values in CG,UNC and CC of aMCI patients suggest that subtle damages of white matter tracts related to memory exist in the prodromal phase of Alzheimer’s disease (AD).Fiber tractography has high sensitivity in detecting early damages of white matter.
