Hyperprotein chow can increase perfusion and filtration of glomerulus,and so result in kidney hypertrophy and damage.Monocytes and macrophages are considered to be a characteristic of diabetic nephropathy(DN),and play a key role in the glomerular sclerotic lesions.At present,hyperprotein chow,infiltration of monocytes and macrophages and overproduction of intercellular adhension molecule-1(ICAM-1) are thought to be involved in the progression of DN.Hyperprotein chow resulting in hyperfiltration may be one of potential mechanisms of ICAM-1 upregulation.

High-efficiency exhalation disinfection device for the patient infected with SARS can also meet the disinfection requirements of the patients with severe respiratory communicable diseases. Connected with the exhaust vent of the breathing mask or the respirator by corrugated tubes, this device gathers exhalation containing a large amount of causative agents through the completely leakproof ductwork and then expels purified air after multiplicate disinfection by high temperature, high pressure and chemical disinfectant. The device can prevent the patient with severe respiratory communicable disease from polluting their surrounding air and thus cut off the route of transmission, reduce the infection rate and the death rate of the person and medical personnel who has made intimmate contact with the patient.

Objective To investigate the effects and mechanism of dexmedetomidine hydrochloride preconditioning against glutamate-induced neurotoxicity.Methods The model of glutamate-induced neurotoxicity was established by the injection of glutamate into lateral cerebral ventricle.Thirty-six SD rats were randomly divided into control group (C group),glutamate-induced neurotoxicity group (G group),Dex1 group and Dex2 group.Dex1 group and Dex2 group received intraperitoneal injection of dexmedetomidine respectively at a dose of 50 μg/kg or 100 μg/kg before glutamate application.Two hours later,the rats were sacrificed and hippocampus was separated to measure the level of SOD and MDA.The rest of each brain was used to measure the degree of brain edema.Pathological changes were observed under microscope with Nissl's staining.Results In contrast to G group,brain edema and MDA concentration in Dex1 group and Dex2 group were significant lower,while SOD concentrations were significantly increased and the pathological change in Dex1 group and Dex2 group were relieved obviously compared to glutamate-induced neurotoxicity group.Conclusion Dexmedetomidine preconditioning can significantly attenuate glutamate-induced neurotoxicity,which is properly related to the inhibition of oxidative-stress reaction.

ABSTRACT:Objective To investigate CA125 and ALDH1 levels in diagnosis and postoperative follow‐up of endometriosis (EMs) .Methods Serum CA125 and ALDH1 levels were tested by enzyme‐linked immunosorbent assay (ELISA) in 105 patients with EMs and 100 healthy subjects who came to our hospital between January 2011 and June 2013 .Results The preoperative serum CA125 and ALDH1 levels of EMs patients were significantly higher than those in the control group ( P<0 .05) .Serum ALDH1 levels in stages I and II of EMs were significantly higher than those in the control group (P<0 .05) ,but there was no difference in serum CA125 level between the two groups ( P>0 .05) .Taking CA125≥35 U/mL and ALDH1≥2 .0 pg/mL as the boundary values ,the specificity , sensitivity ,positive predictive value and negative predictive value of serum CA 125 combined with ALDH1 for diagnosis of EMs were 87 .1% ,91 .6% ,84 .6% and 89 .3% ,respectively .One month after operation ,serum CA125 and ALDH1 levels of EMs patients were decreased significantly (P<0 .05) ,but they were still higher than those in the control group ( P<0 .05) .Six months after operation ,their serum CA125 and ALDH1 levels did not differ from those in the control group (P>0 .05) .Relapse occurred in 1 patient 1 year after treatment and in 6 patients 2 years after treatment ;all these patients had a higher serum ALDH1 level than the control group ,but only 2 of them had a higher serum CA125 level .Conclusion The combined detection of serum CA125 and ALDH1 has a higher sensitivity in diagnosis of EMs .Serum ALDH1 level increases in stages Ⅰ and Ⅱ and recurrent patients and can become a better serum marker for early diagnosis and detection of the recurrence of EMs in patients .

Objective Explore the value of APM histochemical stain technique in the diagnosis of amniotic fluid embolism(AFE).Method The pulmonary tissues taken from autopsies performed in 1988～2001 including 19 AFE cases and 3 babies died of amniotic fluid aspiratory pneumonia(positive control),10 women in labor died of other causes(negative control) were sectioned again and stained by APM method and HE method. Comparative statistical research was carried out on findings from the 2 staining methods. Results By APM stain,amniotic fluid elements could be found in all AFE cases and positive control cases as well as some negative control cases.In addition,we found 1 positive case neglected and 1 false negative case of AFE retrospectively.Statistical comparison revealed that APM stain can elevate the detection rates both for keratinized epithelium and mucus.Conclusion APM staining provided possibility of detecting some amniotic fluid elements that was not distinguished by HE stain. The APM stain is helpful and can be used for AFE diagnosis in routine histological examination.

Objective: To explore the effects of sensory integration training on the behaviors and cognition in children with attention deficit hyperactivity sorder (ADHD) . Methods: Fifty-two children with ADHD (experimental group) were undergone sensory integration training for 60 times and their behaviors were evaluated with the Corners Parents Symptom Questionnaire (PSQ), and the cognition function was determined with the Combined Raven's Test (CRT) and Wisconsin Card Sorting Test (WCST) before and after the training. Another 52 healthy volunteers were recruited as controls and given the corresponding tests described above for comparison of the results. Results: The scores of conduct disorder, compulsion, hyperactivity and hyperactivity index in children with ADHD were decreased significantly than those of controls after training [(0.60 ± 0. 34) vs. (0.68 ± 0.35), (0.92±0.57) vs. (1.25±0.70), (0.82±0.29) vs. (1.08±0.44); P<0.05] .Inaddition, the improvement was found in IQ, categories control, and conceptive level as compared with that before the training [such as IQ, (105. 37 ±22.76) vs. (97. 37 ±24.15); P<0.001], whereas the scores of response error, response error percentage, first category and persistent errors were decreased after the training [such as response error, (39.40 ± 22.22) vs. (46.60 ±23.44), P<0.001] . For the experimental subjects, the scores in the first response number and the persistent errors percentage right after the training were higher compared with the controls [(12.03 ±5.08) vs. (10.65±0.84), (50.75 ±18.35) vs. (39.95 ± 15. 34); Ps<0.05] .Conclusion: The sensory integration training can improve the behaviors and cognition in children with ADHD, but it produces fewer effects on some of the executive functions despite clinical symptom relief to a certain extent.
