Objective To prospectively assess the predictive power of centralization phenomenon in the curative effect of automated PLD.Methods The survey population was consisted of 109 patients with inclusion heraiation demonstrated by CT/MRI,74 men and 35 women with average age of 43.1 years(17~75 years). All were complained of low back pain,with varying degrees of lower extremity pain and altered sensation, lasting for more than 2 months;including one symptomatic disc in 99 patients and two symptomatic discs in 10 patients.Patients were undergone dynamic mechanical spinal test and reported whether the test would aggravate their pain.The assessment included forward flexion,extension,rotation of the trunk to the right and left, rotation to the left with fight extension,rotation to the fight with left extension,and whether straight leg raising in the supine position would aggravate back pain or leg pain.Symptom resposes were categorized into three groups:centralization group(CG),partial-centralization group(PCG)and noncentralization group(NCG). Centralization of pain is the progressive retreat of the most distal extent of the referred or radicular pain toward or to the lumbar midline.Noncentralization of pain is the peripheralization of pain in one or more directions, and no change in the distal-most pain location or intensity.All patients received a single therapy with PLD. Results A follow-up of 109 patients for 3 to 6 months,including 46 cases with 24 as exellent and 22 as good reaching 100% of excellent good rate in CG by MacNab standards;43 cases with 5 as exellent,29 as good,9 as fair and poor,with total effective rate of 79.1% in PCG.Twenty cases of NCG symptoms showed no improvement and therefore surgery was considered.Conclusions Centralization phenomenon occurrence during initial mechanical evaluation is a very accurate predictor for successful PLD outcome.Nonoccurrence of centralization would accurately predict poor PLD outcome and thus helpful as early predictor of the need for surgical treatment.

Objective To investigate the distribution of death among human immunodeficiency virus/acquired immuno deficiency syndrome(HIV/AIDS) cases in Guizhou Province from 1995 to 2017. Methods The HIV/AIDS death cases from 1995 to 2017 were downloaded from “Chinese National Comprehensive HIV/AIDS Prevention and care Information system” in Guizhou Province and were analyzed. Results From 1995 to 2017, Guizhou Province reported a total of 43 794 HIV/AIDS cases and 11 527 deaths according to current address. After excluding missing persons, the HIV/AIDS mortality rate of the province was 29.8%. The proportion of reported HIV/AIDS cases died in the same year ( 21995-2012=139.5, P<0.001; 22012-2015=28.2, P<0.001) and the proportion of HIV/AIDS cases ( 21995-2012=109.1, P<0.001; 22012-2014=57.2, P<0.001) who survived at the beginning but died later in the year all showed a trend being low-high-low. In the analysis of the detection history of death cases, the detection proportion of cluster of differentiation 4(CD4) T-cell and the proportion of antiviral treatment had been increasing year by year. The analysis of the cause of death found that the proportion of death caused by AIDS increased firstly and then declined, and the proportion of death due to excessive drug abuse showed a trend of declining year by year. Conclusions The mortality rate of HIV/AIDS in Guizhou Province was still high, and decreased rather slow. Expanding the coverage of HIV monitoring and screening is one of the key tasks of AIDS prevention and control. CD4+T-cell testing and free antiviral treatment should be strengthened to reduce the mortality rate of HIV/AIDS in Guizhou Province in the future.

OBJECTIVETo establish a method for real-time recording the oxygen consumption of mice under normobaric hypoxia.
METHODSThe experimental apparatus was made up of animal container, filling water control system, electronic balance, hose, a computer with weight recording software, etc. The working principle was that the oxygen consumed by animal was replaced by water filling which was controlled by the pneumatic and hydraulic actuator. The water was weighted by an electronic balance and the weight signal was recorded into excel file at the same time. The accuracy and precision of the apparatus were detected by a 10 ml syringe. The oxygen consumption characteristics of 6 acute repetitive hypoxia mice and 6 normal mice were observed.
RESULTSThe P value for the paired t test was 1 and the CV value was 4%. The survival time and total oxygen consumption of acute repetitive hypoxia mice were both significantly increased compared to normal mice (P < 0.05), which were (58.8 +/- 6.8) min and (46.0 +/- 8.7) min respectively for the survival time and (85.1 +/- 8.5) ml and (73.6 +/- 5.4) ml respectively for total oxygen consumption.
CONCLUSIONThe hypoxia tolerance of the acute repetitive hypoxia mice can significantly improved by taking more oxygen in the animal cabin. The accuracy and precision of the apparatus are high and it can be used for the determination of oxygen consumption in hypoxia research.

OBJECTIVETo investigate the correlation between 18F-FDG standard uptake value (SUV) and expression of GLUT1, MVD and Ki67 in non-small cell lung cancer (NSCLC).
METHODSThirty-three patients with non-small cell lung cancer received preoperative 18F-FDG PET-CT examination and underwent surgery. The expression of GLUT1, MVD and Ki67 were detected by immunohistochemstry. The correlation between the SUV of 18F-FDG PET-CT and the immunohistochemical results of the three above mentioned parameters was analyzed.
RESULTSOf the 33 NSCLC patients, 21 were in stage I, 4 in stage II and 8 in stage IIIa. Positive expression of GLUT1 was found in 22 cases (66.7%, 12 adenocarcinomas and 10 squamous cell carcinomas), and negative expression in 11 cases (10 adenocarcinomas and 1 squamous cell carcinoma). Twenty-four patients (72.7%) showed positive expression of Ki67 (13 adenocarcinomas and 11 squamous cell carcinomas), and other 9 (adenocarcinomas) had negative expression. The positive expression rate of CD34 in this series was 100.0% with a mean MVD of 12.6 +/- 2.9.
CONCLUSIONSUV of 18F-FDG PET-CT is linearly correlated with the expression of GLUT1, but not with the expression of Ki67 or MVD. The expression of GLUT1, Ki67 and CD34 is not correlated with tumor size and lymph node metastasis.
