The immunopathogenesis of IgA vasculitis and IgA nephropathy both demonstrate IgA deposition,and abnormal glycosylation of IgAl molecule is their major pathogenesis.Therefore,it is clinically controversial that they are actually one disease.The present text will delineate their similarities and differences from aspects of epidemiology,clinic,pathology,mechanism and prognosis.

Objective To explore the usefulness of enhanced patient education in increasing the patients' knowledge and awareness of peripherally inserted central catheter (PICC) protection.Methods Totally 200 patients with PICC in Neijiang First People's Hospital from June 2009 to June 2012 were divided into control group (odd numbers,conventional patient education,n =100) and observation group (even numbers,enhanced patient education,n =100) according to their admission numbers.The patients' knowledge and awareness of PICC protection were analyzed after treatment,and the incidences of adverse events and catheter indwelling time were also compared between these two groups.Results Compared with the control group,the observation group had significantly higher PICC protection knowledge rate (91％ vs.78％,P =0.001),awarehess rate (95％ vs.80％,P=0.011),lower incidence of adverse events (1％ vs.5％,P =0.034),and longer PICC indwelling time [(125.8 ± 10.6) d vs.(106.7 ±8.2) d,P =0.026].Conclusion Enhanced patient education can effectively enhance the patients' knowledge and awareness of PICC protection.

In recent years,it is a tendency to substitute acute kidney injury (AKI) foracute renal failure (ARF)in the aspect of international nephrology and emergency medicine.Compared with the past,the causes for AKI in children at present has been transferred from primary kidney disease to multi-factors,moreover,the morbidity and mortality of AKI is staying at a high level.From the perspective of epidemiology this paper briefly analyses the common cause,mortality and morbidity of AKI in children.

Objective:To study the effect of the three kinds of EE on the cognitive function and the expression of SYN and MAP-2,and the dentritic growth of pyramidal cells of the cerebral cortex in rats.Method:Forty-eight male SD rats were divided into preserving the physique EE group (EE1),preserving the spirit EE group (EE2),preservation for both physique and spirit EE group(EE3) and standard group (SE),12 rats in each group.Rats were put into the three kinds of EE or standard cages after pre-training.The environmental enrollment lasted for 14 days and followed by a 6-days Morris water maze test.After the Morris water maze test,all the rats were sacrificed for histological study,including using the immunohistochemistry method to detect the expression of SYN and MAP-2,and using the Golgi-Cox staining to study the dentritic growth of pyramidal cells in cerebral cortex.Result:In the Morris water maze,the EE3 group exhibited shorter escape latency than the MCAO+SE group (P＜0.05) on day 5,while no significant differences were seen for the time spent in the target quadrant among the 4 groups (P＞ 0.05).The results of immunohistochemical staining of SYN showed that the expression of SYN was the lowest in the SE group,and there was no significant difference between EE1 and EE3 groups but significantly higher than the EE2 group.The expression of MAP-2 was the lowest in the SE group,and there was no significant difference of expression between EE1 and EE2 groups but significantly lower than the EE3 group.The results of Golgi-Cox staining showed that there was no difference of the dentritic branch among groups in mPFC (P＞ 0.05) while the spine density of the EE1 group was significantly greater than that of the SE and EE2 groups (P ＜ 0.05),but significantly lower than that of the EE3 group (P ＜ 0.05).Conclusion:Two weeks of preservation from both physique and spirit EE can improve the cognitive function,and promote the expression of MAP-2 and SYN and the dentritic growth of pyramidal cells in normal rats.

Objective To observe the correlation between nuclear factor ?B(NF-?B) expression and apoptosis after hypoxia-ischemia brain damage(HIBD).Methods Forty-eight 7-day newborn Sprague-Dawley(SD) rats were randomly divided into 2 groups: control group (n=24) and HI group (n=24).The expression of NF-?B in the hippocampus was detected by immunohistochemical techniques.The apoptosis of the hippocampal cells was detected by terminal deoxynucleotidyltransferase-mediated 2-deoxyuridine 5′-triphosphate-biotin nick end labeling(TUNEL)straining.Results The expression of NF-?B in hippocampal cells increased at 6 h after HIBD,peaked at 48 h,and lasted till 72 h when compared with control group(Pa

0.05). (2) The average squeezing anal pressure and the duration of anal squeezing decreased in the experiment group, which were significantly different from those in the control group ( P

Earthquake may result in various urologic problems by direct injury of urologic organs or by spinal cord injury.This article introduces the main urologic problems after earthquake,classified into early and long-term.Such as urinary retention,oliguria or anuria,renal injury,bladder and urethra injury,neurogenic bladder caused by spinal cord injury,et al.We analyze the causes of the problems and discuss the correct management principle,all kinds of rehabilitation measures to reduce the complication and sequela,also the problems should be cautioned during the long term follow-up.

Objective To investigate the role of contrast-enhanced ultrasound (CEUS) on the diagnostic efficacy of ultrasound-guided percutaneous biopsy of peripheral lung lesions. Methods Ninty-six patients with pleural-based lesions underwent percutaneous ultrasound-guided biopsy. Of the 96 patients,54patients underwent CEUS before biopsy and enhancement information was referred for the selecting of tissue sampling site. The rest of 42 patients didn' t undergo CEUS before biopsy. The difference in the diagnostic accuracy between the two groups was analyzed to evaluate the value of CEUS before biopsy.Results Of the 52 patients in the CEUS group,48 were malignant,and 6 were benign. Of the 42 patients in the un-CEUS group,36 were malignant, and 6 were benign. Necrosis (areas lacking of enhancement) was demonstrated in 41.7％ (20/48) of the patients with malignant lesions in CEUS group, and necrosis incidence was increased with the increase of the dimension of the malignant lesions. No necrosis area was demonstrated in 6 benign lesions. The rate of successful initial biopsy in CEUS group (98.1 ％ ,53/54) was statistically higher than that in un-CEUS group ( 85.7％, 36/42 ) ( P ＜ 0.05 ). Tissue necrosis and denaturalization attributed to most of the inconclusive pathologic diagnosis. Conclusions CEUS before transthoracic peripheral lung lesion biopsy improved the diagnostic accuracy of the procedure by providing information for differentiating viable or necrotic tissue and consequently provide more accurate information about the site of biopsy.

Objective To determine the dangerous depths of acupuncture at Yamen(GV15) and Fengfu(GV16) in different age groups and different body types based on MRI measurements and to analyze their distribution chracteristic .Methods 98 patients of different age groups in the affiliated hospital of Hainan Medical College from June to December 2012 were selected and the each age group was divided into 3 types :asthenic type ,moderate type and endomorphy type according to the Rohrer index .All images took the median sagittal position .The dangerous depth was measured according to the clinical operation habit and actual feasibility .Re-sults The difference in the acupuncture depth of GV15 and GV16 among different asthenic type patients in different age groups had no statistical significance ;in the moderate type patients ,the difference in the acupuncture depth of GV15 and GV16 between the age group of 18- <45 years and 45-60 years had the statistical significance(P=0 .029 ,P=0 .018);in the endomorphy type pa-tients ,the difference in the acupuncture depth of GV15 and GV16 between the age group of 45-60 years and the other age groups had the statistical significance(P<0 .05) .Conclusion The dangerous depth of GV15 and GV16 had no correlation with age ,but is positively correlated with the Rohrer index ,i .e .,the dangerous depth of GV15 and GV16 is increased with the increase of Rohrer index .

This study was aimed to evaluate effects of traditional Chinese medicine ( TCM ) five elements music therapy on the quality of life for both senior and non-senior advanced cancer patients , and improve TCM com-prehensive treatment mode . A total of 170 patients were stratified according to 70-year-old in a randomized controlled trial ( RCT ) with a parallel single-blind design . The ratio of patients among three groups was 2:2:1 . In the experimental group , TCM five elements music was given in the treatment . In the positive control group , western music was used in the treatment . And in the negative control group , no music was given in the treat-ment . The treatment was given for 30 min , 5 times per week . And the observation duration was 3 weeks . The Hospice Quality of Life Index-Revised ( HQOLI-R ) , Karnofsky Performance Scale ( KPS ) and Symptom Diary Score recorded by patients were used in the evaluation . The results showed that when comparing HQOLI-R , KPS and Symptom Diary Score before and after treatment among all advanced cancer patients in each group , there was a significant difference before and after treatment in the TCM five elements music therapy group ( P< 0 . 05 ) . But there was no significant difference before and after treatment in the western music therapy group or the negative control group ( P > 0 . 05 ) . It was concluded that TCM five elements music therapy is effective in improving quality of life and subjective symptoms for both senior and non-senior advanced cancer patients . However , the sensitivity of using the Symptom Diary Score as an evaluation index among senior patients still needs to be further proved .
