Objective To investigate the expression and chnical significance of β tubulin Ⅲ in locally advanced cervical cancer (LACC).Methods The expression of β tubulin Ⅲ in tumor tissue of 47 patients with LACC was detected by immunohistochemical SP method.The relationship between expression of β tubulin Ⅲ and neoadjuvant chemotherapy (NACT) with paclitaxel,clinical data were analyzed retrospectively.Results The response rate of NACT was 72.3％ (34/47).The β tubulin Ⅲ positive expression rate was 72.3％(34/47),(+) expression rate was 40.4％(19/47),(++) expression rate was 12.8％(6/47),(+++) expression rate was 19.1％(9/47).The response rate of NACT in patients with (++) and (+++) expression was significantly lower than that in patients with (-) and (+) expression [46.7％(7/15)vs.84.4％ (27/32),P =0.007].The expression of β tubulin Ⅲ was related to pathological grade (P =0.021),it was not related to pathological type,clinical stage,status of lymph node metastasis (P =0.822,0.336,0.839).Conclusions The NACT of paclitaxel combined with cisplatin is effective to LACC.The abnormality expression of β tubulin Ⅲ in LACC tissue relates to drug resistance of paclitaxel and biological behavior of cervical cancer,it may be an index to predict prognosis of cervical cancer.

Objective System of pressure breathing for +Gz (PBG) has been incorporated into service in the high performance fighter aircraft,but there were significant differences among PBG pressure schedules used in different countries.The purpose of this study was to define an optimal pressure schedule in PBG system.Method Five male subjects wearing GZ-2 anti-G suit and medium-sized bladder vest,plus PBG with 1.6,2.4,and 3.2 kPa/G pressure schedules,respectively,were exposed to rapid onset (3.0 G/s) centrifuge +Gz runs.+Gz protection of PBG with each of the three pressure schedules were measured and the subjective ratings were collected.Result The +Gz protection afforded by PBG with 1.60,2.40,and 3.20 kPa/G pressure schedules were 2.00±0.31,2.54±0.32,and 2.44±0.31 G,respectively.Subjective ratings showed that the PBG with 2.40 kPa/G pressure schedule was better than the other two.Conclusion Our data suggest that a PBG pressure schedule of 2.4 kPa/G in PBG system is optimal.It not only assures the anti-G performance of PBG,but also reduces its side effects.

Objective To detect the volume changes of cerebral gray and white matter in patients with maintaining hemodialysis using voxel-based morphometry(VBM) and to correlate these changes with cognitive function. Methods Forty-two patients with maintaining hemodialysis and 41 age and sex matched normal subjects were recruited in this study. MMSE was obtained to evaluate their neuropsychiatric conditions. Whole brain high-resolution T1WI was performed on 3.0 T MR scanner in both patients and normal controls. The data were analyzed by VBM based on SPM8, using analysis of functional neuroimages (AFNI) software package with the Monte Carlo simulation method(AlphaSim method) for multiple cluster level comparisons correction. Independent sample t test analysis was used to compare the volume of gray and white matter between the patients and normal controls. In addition, Stepwise multiple linear regression analysis was performed to explore the correlation between the voxel value of cerebral volume changes area and dialysis duration and clinical laboratory examination, and Spearman correlation analysis was used for the correlation between the left insula voxel values and neuropsychological test scores. Results Compared with normal controls, patients showed significantly decreased volume in the grey matter of the right putamen, the left putamen, the left insula (numbers of voxel in clusters were 455, 561, 162, t=-9.5681,-5.9516,-5.7185,P<0.001, AlphaSim-corrected). There was negative correlation between decreased grey matter volume of the right putamen[(0.53 ± 0.12)mm3]and the left putamen[(0.48 ± 0.12)mm3] and dialysis duration [19.0(1.5-114.0)months] (r=-0.330,-0.307,P<0.05). MMSE score of patients[29(21-30)score] was significantly lower than normal controls[30(28-30)score] (Z=-30.58,P<0.01). Decreased grey matter volume of the left insula [(0.39 ± 0.12) mm3] was positively correlated with MMSE(r=0.320, P<0.05). Conclusions The patients with maintaining hemodialysis show grey matter atrophy which is associated with neurocognitive dysfunction. Dialysis duration may be an important risk factor for decreased gray matter in patients with maintaining hemodialysis.

OBJECTIVETo observe the differences in onset time and the overall efficacy of the acupuncture therapy of dredging Governor Vessel and regulating mentality combined with fluoxetine and the fluoxetine for post-stroke depression(PSD).

METHODSSixty-three patients were randomly divided into an acupuncture intervention of dredging Governor Vessel and regulating mentality group(acupuncture and medication group, 33 cases) and a control group (medication group, 30 cases). In the medication group, 20 mg fluoxetine was used by oral administration, once a day at 7:00 in the morning, continuously for 4 weeks. In the acupuncture and medication group, based on the oral administration of fluoxetine, the acupuncture intervention of dredging Governor Vessel and regulating mentality was applied mainly at Baihui(GV 20), Fengfu(GV 16), Shenting(GV 24), Shuigou(GV 26), Dazhui(GV 14) and Shendao(GV 11), once a day, 6 times a week, continuously for 4 weeks. Twenty-four items in Hamilton Depression Scale(HAMD), modified Edinburgh Scandinavia Stroke Scale(MESSS) and activity of daily life scale(ADL, Barthel index, BI) were used before and after 2-week and 4-week treatment. The efficacy was compared between the two groups.

RESULTSAfter 2-week treatment, the HAMD score and the MESSS score in the acupuncture and medication group were obviously decreased and the BI score was apparently increased(all P<0. 01). In the medication group, however, the score of every scale was not statistically different from that before treatment(P'>0. 05). After 4-week treatment, HAMD scores and MESSS scores in the two groups were obviously decreased and the BI scores I were apparently increased(all P<0. 01). After 2-week and 4-week treatment, the HAMD scores and the MESSS scores in the acupuncture and medication group were lower than those in the medication group and the BI scores were higher than those in the medication group(P<0. 01, P<0. 05). The total effective rate of anti-depression (97. 0%, 32/33) the total effective rate of nerve function impairment(90. 9%, 30/33) and the total effective rate of daily life activity(97. 0% 32/33) in the acupuncture and medication group were better than 80. 0% (24/30), 80. 0%(24/30), 83. 3%(25/30) in the medication group(all P<0. 05).

CONCLUSIONThe acupuncture therapy of dredging Governor Vessel and regulating mentality could reduce the onset time of anti-depression medicine treatment of PSD and enhance the overall efficacy. Therefore, it enhances the clinical compliance.

OBJECTIVETo investigate the analgesic and sedative effects of inhaling a mixture of nitrous oxide and oxygen on burn patient during and after dressing change.

METHODSA total of 240 burn patients hospitalized in the Institute of Burn Research of Changhai Hospital Affiliated to the Second Military Medical University, Department of Burns of the First People's Hospital in Zhengzhou, and Department of Burns and Plastic Surgery of General Hospital of Ningxia Medical University from October 2011 to September 2012 were enrolled in our study, and they were all in accordance with the inclusion criteria. The 240 patients were divided into control group (n = 60, treated with inhalation of oxygen during dressing change) and treatment group (n = 180, treated with inhalation of a mixture of 65% nitrous oxide and oxygen during dressing change) according to the computer-generated list of random number. The other treatments in control group and treatment group were the same. Before, during, and after dressing change, heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation (SO2), and adverse effects were observed. The degree of pain and anxiety felt by the patients were respectively evaluated with the visual analogue scale (VAS) and Chinese version of the burn specific pain anxiety scale (C-BSPAS) at the same time points as above. Data were processed with analysis of covariance, chi-square test, analysis of variance, and rank sum test.

RESULTSThere were no significant differences between control group and treatment group in the levels of HR, SBP, DBP, and SO2 before dressing change (with F values respectively 0.76, 0.06, 1.11, 0.70, P values all above 0.05). Compared with those of control group, the levels of HR, SBP, DBP, and SO2 in treatment group were significantly ameliorated during dressing change (with F values respectively 81.78, 146.36, 226.44, 205.62, P values all below 0.01). After dressing change, the levels of DBP in the two groups were close (F = 0.31, P > 0.05), but the levels of HR, SBP, and SO2 showed statistical differences (with F values respectively 7.02, 8.69, 12.23, P < 0.05 or P < 0.01). Before dressing change, the VAS scores were approximate between control group and treatment group (Z = 0.21, P > 0.05). Compared with those in control group (9.4 ± 0.7, 1.7 ± 2.5), the VAS scores were significantly lowered in treatment group during and after dressing change (1.6 ± 1.3, 0.7 ± 1.1, with Z values respectively 11.84, 3.35, P values all below 0.01). There was no significant difference in C-BSPAS score between control group and treatment group before dressing change (Z = 0.62, P > 0.05). Compared with those in control group (75 ± 13, 73 ± 12), the C-BSPAS scores in treatment group were decreased during and after dressing change (9 ± 15, 9 ± 14, with Z values respectively 11.91, 12.28, P values all below 0.01). There were no obvious adverse effects in two groups before, during, and after dressing change.

CONCLUSIONSA mixture of nitrous oxide and oxygen seems to have obvious analgesic and sedative effects on burn patients during dressing change, and it can be widely used.

Objective: To evaluate the effect of vaccine and provide scientific evidence for prevention and control of influenza virus, this study aims to analyze the characteristics of genomic variation of influenza A (H1N1) pdm09 viruses in Inner Mongolia. Methods: The 16 viral strains were selected randomly according to the influenza A (H1N1) pdm09 viruses isolated from network laboratories in Inner Mongolia, 2013-2017. The hemagglutinin(HA) and neuraminidase(NA) genomic sequences were obtained by using RT-PCR and sequencing, and genomic characteristics were analyzed via bioinformatics. Results: Compared to the A/California/07/2009 vaccine strain, the relatively obvious variation of antigen of influenza A (H1N1) pdm09 viruses in Inner Mongolia since 2014, and the vaccine provided a poor protection to influenza A (H1N1) pdm09 virus infection, while the A/Michigan/45/2015 vaccine strain recommended by WHO recently has a satisfactory protective effects. Several viral isolates from Inner Mongolia increased the binding force of virus in human upper respiratory tract because of D222N and D222G substitution within HA. E119K and H275Y substitution within NA gene of viral strains, suggesting that the viruses were resistant to NA inhibitors. Conclusions The influenza A (H1N1) pdm09 viruses had gradual variations as time went on, and the WHO recommended vaccine was relatively lagging. Virulent strains and drug-resistant strains appeared in the population, and the genetic characteristics of influenza virus surveillance should be strengthened to find the new mutants of virus in time, which provide evidence for the prevention and control of influenza.
