Objective To evaluate lactulose breath hydrogen test in diagnosis of small intestinal bacterial overgrowth in children.Me-thods Thirty-five children,aged 3 to 13 years old with mean (7.72?3.06) years old presented with chronic diarrhea,abdominal pain and flatulence.Among them,18 cases were male and 17 cases were female.Breath hydrogen test was carried out after the administration of a 0.5 g?kg-1 or 10 g lactulose,which was 100 g?L-1 solution.After the ingestion of lactulose,the breath hydrogen was collected in every 20 minutes and up to 3 hours.Small intestinal bacterial overgrowth was diagnosed as positive when the hydrogen concentration increased more than 20 mg?m-3 in a sample.Results Eighteen cases in 35 (51.43%) children were positive and 17 cases were negative.Among these positive cases,8 cases in 18 (22.86%) patients were typically double peaks in breath hydrogen concentrations.Among the causes of small intestinal bacterial overgrowth in children,4 cases with chronic superficial gastritis,4 cases with chronic bacterial enteritis,2 cases with malnutrition and anorexia,1 case with volvulus of stomach,1 case with massive resection of small intestine,1 case with steatorrhea and 5 cases with unknown causes.Four cases of chronic bacterial enteritis were gained remission by antimicrobial agents.The other cases were treated by lac-to-and bifidbacteria probiotics.Seven patients of the clinical systems were controlled,3 cases were improved remarkably and 4 cases were failed.Conclusions The lactulose breath hydrogen test is validated as screening test in the diagnosis of small intestinal bacterial overgrowth in children.Antimicrobial agents and bifidbacteria probiotics is effective in treatment of small intestinal bacterial overgrowth.

Objective Few reports are seen about the effects of cooling blood and removing stasis on nephrin and podocin . This study was to evaluate the therapy of cooling blood and removing stasis for Henoch -Sch?nlein purpura nephritis ( HSPN) and its ac-tion mechanisms by observing the effects of Danshao Granular Ⅲ on hematuresis , proteinuria and the expressions of nephridial nephrin and podocin in HSPN rats . Methods Twenty-one SD male rats were e-qually randomized to a blank control , an HSPN model , and a Dan-shao group.At 13 weeks after modeling , the animals in the model group were treated intragastrically with distilled water , while those in the Danshao group with Danshao Granular Ⅲtwice daily for 4 weeks. Then, the urinary red blood cell ( RBC) count was examined , the
24 h urinary protein quantity determined , the glomerular mesangial changes observed under the light microscope , the protein expres-sions and distributions of nephrin and podocin detected by indirect immunofluorescence , and their mRNA expressions determined by re-al-time PCR. Results The urinary RBC count and 24 h urine protein quantity were significantly higher in the HSPN model than in the blank control group (26.5/HP vs 0.3/HP and [2.214 ±1.090]g/24 h vs [0.624 ±0.354]g/24 h, both P<0.01).The model rats showed obvious pathological changes in the renal tissue .The urinary RBC count and 24 h urine protein volume were remarkably de-creased in the Danshao group as compared with the models (0.8/HP vs 26.5/HP and [1.000 ±0.651]g/24 h vs [2.214 ±1.090] g/24 h, both P<0.01).The pathological changes in the renal tissue of the Danshao group were reduced in comparison with those of the model group.The protein expression of nephrin was higher in the former than in the latter (65.975 ±14.414 vs 43.520 ±0.632, P<0.01) and so was that of podocin though with no statistically significant difference (P>0.05).The distributions of nephrin and podocin were improved after Danshao treatment .The mRNA expressions of nephrin and podocin were markedly higher in the Danshao group than in the HSPN models (0.530 ±0.089 vs 0.117 ±0.021 and 0.490 ±0.160 vs 0.033 ±0.025, P<0.05). Conclusion Danshao Granular Ⅲ, with its main action mechanisms of cooling blood and removing stasis , can effectively reduce urinary RBC count and urinary protein quantity and improve the symptoms of HSPN in rats .

Objective To study in vitro the effects of low-intensity pulsed ultrasound (LIPUS) on the proliferation and differentiation of cultured myoblasts,and to explore the cellular and molecular mechanisms behind any therapeutic effect of LIPUS.Methods Myoblasts were isolated from the skeletal muscles of mice and cultured in vitro.Treatment and control groups of proliferating and differentiating myoblasts were defined.The treatment groups were exposed to LIPUS at 1.5 MHz and a spatial and temporal average intensity of 30 mW/cm2,for 20 min daily,the proliferation group for 6 consecutive days and the differentiation group for 4 consecutive days.The cell proliferation kinetics of the proliferation group were analyzed using flow cytometry.The expression of myogenic regulation factor MyoD and heme oxygenase-1 (HO-1) in the proliferation group,and of myosin heavy chain (MHC) in the differentiation group were examined by immunofluorescent staining.Myoblast fusion indexes were analyzed.Results In the LIPUS treatment groups the proliferating myoblasts had a higher ratio of active cells in the G2 and S phases (19.30％ ±5.14％,37.00％ ±8.72％),compared with the controls (10.33％ ± 1.53％,25.00％ ±4.36％),and the proliferation index increased significantly.The expression of HO-1 was up-regulated,while MyoD staining was unchanged.During the induction of differentiation,the myoblasts of the treatment group fused into smaller myotubes and the myoblast fusion index (18.73％ ± 6.81％) was significantly lower than that of the control group (37.52％ ± 11.23％),while MHC expression did not change markedly.Conclusion LIPUS can promote myoblast proliferation while inhibiting their differentiation,but it does not affect the cells' myogenic properties.HO-1 may be involved in the regulation process.

Objective To assess the clinical value of high-frequency electrocautery in the treatment of massive hemorrhage of presacral venous plexus. Methods The clinical data of 8 patients with presacral venous hemorrhage treated with high-frequency electrocautery from February 2005 to March 2008 were analyzed. Once the presacral venous hemorrhage happened, the bleeding site was pressed with a gauze or finger and the accumulated blood was aspirated. Then, while simultaneously withdrawing the gauze or finger over the bleeding sites, high-frequency electrocautery was applied with a power of 80-100 W to coagulate all the bleeding sites. Results High-frequency electrocautery was used to stop bleeding in the 8 patients, and no electrocautery related complica-tions occurred postoperatively. Conclusions High-frequency electrocautery for massive hemorrhage of presacral venous plexus is simple, efficient and safe.
