ABSTRACT
Objective To explore the insulation effect of the coating so as to relieve the influence of solar overtemperature on the tent system.Methods The tent had an integrated structure with multi cavity and air column support,and the confined space was composed of the dual-layer tent body.There were 4 measuring points in the tent,of which,one was at the filter vent,two ones at the ceiling lamp and the remained one above the curtain in the buffer area.The tent was deployed in summer outdoor environment,four thermographs were used for real-time recording of intemal temperature changes in the tents with or without coating,and the recording began at 8:00 am and stopped at 5:00 pm.Comparison proved there was no significant differences between the measured values by the four thermographs (P＞0.05),and correlation analysis was executed based on numerical trend and variance analysis.Results The coating tent had the internal temperature lower than that in the non-coating tent,which had low mean temperature and low temperature range.The internal temperature in the coating tent was lower than ambient temperature at noon and afternoon,which meant the coating tent could lower the temperature effectively even in the duration at high temperature.Concusion Thermal insulation coating applied to the tent relieves the solar overtemperature effect effectively,and thus enhances the the tent's thermal environment adaptability.

ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the therapeutic effects of three different intervertebral fusion with bone graft and internal fixation in the treatment of cervical spondylotic myelopathy.</p><p><b>METHODS</b>In the retrospective study, 83 patients (38 males and 45 females, with an average age of 69 years) with cervical spondylotic myelopathy were divided into three groups. The patients in three groups were treated by autogenous iliac bone grafting (Robingson grafting) with anterior cervical plate-screw fixation, Pyramesh with anterior cervical plate-screw fixation and BAK fixation respectively. JOA scores and the bony fusion time were recorded and the results were evaluated by numeric computer system.</p><p><b>RESULTS</b>The JOA scores of all the patients were higher than those before surgery (t = 1.55, P < 0.05). There were no statistical difference of JOA scores in the three groups (F = 2.51, P > 0.05).</p><p><b>CONCLUSION</b>It is concluded that internal fixation of the three types is promising to the treatment of cervical spondlotic myelopathy. Robingson grafting with anterior cervical plate-screw fixation provides good stability and bony fusion. BAK is better technically required but there was height loss in clinic. Pyramesh with anterior cervical plate-screw fixation combines the merits of both two techniques above but the cost is higher.</p>

<p><b>OBJECTIVES</b>To understand the hormone levels in male senile dementia patients and the effects of testosterone supplement theraphy (TST) on male senile dementia.</p><p><b>METHODS</b>The general health condition, mental health condition, hormone levels, and some other aspects were evaluated in 9 patients with male senile dementia without significant contradiction for TST. 9 patients were treated with oral testosterone undecanoate 120 mg per day for six weeks, and relative changes were observed, detected and recorded.</p><p><b>RESULTS</b>In 9 cases of male senile dementia, the average score was 5.33 in mini-mental state examination (MMSE), 14.56 in Hamilton depression scale (HAMD), 5.0 in geriatric depression scale (GDS), 32.56 in partial androgen deficiency of the aging male (PADAM) measuring form. The volume of testis was small (8.33 ml on average). After 1 week of having finished TST, the levels of serum testosterone (T) dropped significantly (dropped from average 2.88 ng/ml to 2.47 ng/ml, P < 0.05) in 9 patients with TST. General evaluation with clinician's global impression(CGI) for 9 patients showed 2 cases fail and 7 cases with progress (3 of them progress significantly). Average score dropped in HAMD form (10.67) and PADAM form (28.11). Physical strength and psychological status improved significantly, but vasomotor symptoms and sexual function failed response to the treatment.</p><p><b>CONCLUSIONS</b>The levels of androgen is low, and the symptoms of androgen deficiency are readily seen in male senile dementia. TST can improve life quality of most patients to some extent.</p>

<p><b>OBJECTIVES</b>To explore the incidence, causes, and significance of altered bowel habits in chronic prostatitis.</p><p><b>METHODS</b>Investigating the incidence of altered bowel habits in chronic prostatitis, analyzing some possible causes to induce the symptom, such as course of disease, vegetative nerve functional disturbance, inflammation in expressed prostatic secretions, and digital rectal examination. Following up the improvement of altered bowel habits after effective treatment of chronic prostatitis.</p><p><b>RESULTS</b>The incidence of altered bowel habits was 31.40% in 379 chronic prostatitis patients. The detected congestion and swelling of prostate was closed related to altered bowel habits in chronic prostatitis. The incidence of improvement of altered bowel habits after effective treatment of chronic prostatitis reached to 78.79%.</p><p><b>CONCLUSIONS</b>Congestion and swelling of prostate might be the main causes for altered bowel habits in chronic prostatitis. Altered bowel habits should be considered as a common symptom and cure standard for chronic prostatitis.</p>
