In recent years, microRNAs were shown to be one of the key factors in post transcriptional gene regulation which are involved in occurrence, development of many diseases. In the field of kidney disease research, the role of microR?NAs attracted more and more attention. Diabetic nephropathy is one of the major causes of end-stage renal disease, whose pathogenesis however has not been fully elucidated yet. This article reviews the role of microRNAs in the pathogenesis of dia?betic nephropathy.

Objective To investigate the effect of adenosine on rats with acute renal failure(ARF) resulting from ischemia-reperfusion(IR).Methods The model of renal IR injury rats was induced by nipping bilateral renal pedicels of rats with non-traumatic forceps for 40 minutes.The first adenosine group was given adenosine 10 mg/kg intraabdominally at 2 hours before IR.The second adenosine group was given the same adenosine at 40 minutes after IR.Serum creatinine(Scr) levels,the proportion of apoptosis of renal tubular cells(RTCs) and the pathological changes of renal tissue were observed separately in every group at 2,6,12 hours after IR.Results 1.At 12 hours after IR,in IR group Scr levels and apoptosis of RTCs count were(198.56?13.35) ?mol/L and 26.50?2.07,which were increased significantly compared with sham group.In the first and second adenosine groups,they were(113.85?(12.90) ?mol/L),14.67?3.44 and(218.79?37.65) ?mol/L,20.83?5.27,respectively,and all of them were higher than those in sham group(all P0.05).Conclusions Adenosine which is given to rats with IR before IR may be an effective pharmacological agent for prevention and treatment of renal IR injury.The mechanism may be relevant to saving energy and reducing cellular apoptosis.

Objective To study the inhibitive effect of interleukin-4(IL-4) and (or) IL-10 on cell apoptosis of renal ischemic-reperfusion injury(IRI) in rats and its mechanism.Methods Thirty female Sprague-Dawley rats were divided into five groups(n=6): sham-operated group,operation+9 g/L NaCl control (NaCl group),operation+IL-4(IL-4 group),operation+IL-10(IL-10 group),operation+ IL-4+IL-10 (IL-4+IL-10 group). The animal model of IRI was set up by clamping bilateral renal pedicles for 45 min.When the clamp was loosed, relevant agents was injected in every group. Apoptosis of renal epithelial cells (TUNEL method) was obserued.Results IL-4 could not reduce level of apoptosis of renal epithelial cells.To some extent,IL-10 could reduce level of renal epithelial cells. The combination of IL-4 and IL-10 was more effective in inhibiting apoptosis of renal epithelial cells.Conclusion The combination of IL-4 and IL-10 is effective in inhibiting apoptosis of renal epithelial cells, indicating that it has a relationship in preventing renal histological and functional damage.

Objective To investigate the signal transduction of bFGF to regulate the colorectal carci- noma cell growth via PI3K/PKB pathway.Methods MTT assay was used to determine the suppressive effect of bFGF on the growth rate of LoVo cell;(?-~(32)P)ATP incorporation assay was used to detect the increased activity of PKB in LoVo cell;the RT-PCR technique was used to test the expression of cyclin A;Western Blot analysis was used to detect the expressions of PKB and cyclin A protein.Results When the bFGF worked on the LoVo cell at various times,it was found that the PKB activity of the LoVo cell was increased by the(?-~(32)P) ATP incorporation assay.By preprocessing by the depressor-LY294002 and bFGF,the activity of PKB was sig- nificantly reduced(P

objective Microbial limit test(MLT)for Dahuang Zhechong pill was established and verified to supply scientific foundation for the establishment of MLT for antibacterial and anti-inflammatory Chinese patent medicine,and to supply principle guidance for the verification of the method issued in Chinese pharmacopoeia(2005 edition);meanwhile the antibiogram of Dahuang Zhechong pill was probed,which can provide evidence for its clinical administration.Methods With centrifugal sedimentation method and culture medium diluted method,the recovery test was done on each tested bacterial strain to validate the accuracy and feasibility of MLT.Results Dahuang Zhechong pill had a stronger inhibitory effect on staphylococcus aureus and bacillus subtilis,had a weak inhibitory effect on escherichia coli,and had no effect on candida albicans and aspergillus niger,indicating that the antimicrobial spectrum of Dahuang Zhechong pill is Gram-positive bacteria.Conclusion Centrifugal sedimentation method combined with culture medium diluted method can eliminate the anti-bacterial effect of Dahuang Zhechong pill during the experiment,thus the microorganisms in the polluted pill can be detected successfully.

Objective:To investigate the efficiency of CBCT in the diagnosis of impacted maxillary anterior teeth and the treatment effect of different guided eruption methods. Methods:34 impacted maxillary anterior teeth in 30 patients were examined by panoramic films and CBCT, the dental crowns, root, eruption space and other related items were measured and compared between 2 examinations. 20 cases were treated by closed guided eruption and traction( CGET) technique, 10 cases by circumferential supracrestal fibrotomy and exposed traction( CSF-EE) , results were compared. Results: CBCT was more effective than panoramic films in the revelation of tooth root bending, apical pore closure and eruption measurements(P<0. 05). 7-10 d after treatment 5 out off the 10 casses treated by CSF-EE showed different degrees of clinical crown elongation, poor gum appearance and low height of alveolar ridge as insufficient periodontal attachment. However, the treatment of CGET for 26 teeth (76. 47% of all cases) was highly successful and received very satisfactory re-sults, the rest 8 teeth (23. 53% of all cases) showed mediocre satisfaction. Conclusion: CBCT can accurately display the position, shape, relation with adjacent teeth of the impacted teeth. Closed guided eruption and traction is more effective for the treatment.

Objective To explore the application of event related potentials (ERPs) in the comprehensive intervention for attention deficit hyperactivity disorder (ADHD) in children. Methods P 300 of ERPs and Conners' measuring scale were tested in 31 children with ADHD before and 6 months after comprehensive intervention. At the same time, P 300 was tested in 36 healthy children as control. Results In the children with ADHD, the P 300 latency was longer and amplitude was lower than those in the healthy children before comprehensive intervention (P

Objective To investigate the prevalence of hypertension and its related factors in Hulunbeier Mongolian region. Method A stratified multistage sampling was used to select residents aged 18 and over in a town of Hulunbeier region. 453 persons served as subjects for this questionnaire survey. Their blood pressure, height, weight, waist circumference were measured and body mass index (BMI) were calculated. Then an analysis of the prevalence of hypertension and its related risk factors were performed. Results The hypertension prevalence rate was 34.5%, the standardized rate was 45.4%, and the prevalence in men (48.9%) was significantly higher than that in women (25.4%) (P50 (OR=11.312, 95%CI 4.309~22.132), BMI (2.255, 1.180~4.311), gender (OR=2.788, 1.461~5.323) and drinking (2.306, 1.287~4.134) were significantly related to hypertension. Conclusion The standardized prevalence of hypertension in Hulunbeier Mongolian region is higher than the average prevalence in China, 2002. Old age, abdominal obesity, overweight or obesity, male and alcohol drinking were the main risk factors for hypertension in this region. The government and the health sector should strengthen the health education of healthy lifestyle and health promotion and the control.
