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.

To evaluate the efficacy and safety of limbal relaxing incision ( LRl) for correcting corneal astigmatism during implantable collamer lens ( lCL) surgery.METHODS:A total of 185 eyes of 105 patients with high myopia and corneal keratometric astigmatism were included in the study. lCL surgery with concomitant relaxing incision was performed in 105 eyes of 60 patients in LRls group ( Group A) . Eighty eyes of 45 patients only underwent lCL surgery were in control group ( Group B) . All patients undergone ophthalmic examination that included uncorrected visual acuity ( UCVA ) , best -corrected visual acuity ( BCVA ) , Pentacam analysis system to observe the changes of corneal astigmatism before and 1wk, 1 and 3mo after surgery.RESULTS: Respectively comparing UCVA between two groups in 1 and 3mo postoperatively, the P values were considered statistically significant ( P < 0. 05 ). But, respectively comparing BCVA between two groups in 1wk, 1 and 3mo postoperatively, the P values were considered no statistically significant ( P > 0. 05 ). Preoperative corneal astigmatism was 1. 52 ± 0. 55D in group A and 1. 48 ± 0. 57D in group B, there was no statistically significant difference (P>0. 05). One week postoperatively, the astigmatism was 0. 55 ± 0. 41D in group A and 1. 20 ± 0. 48D in group B. One month postoperatively, the astigmatism was 0. 60 ± 0. 38D in group A and 0. 93 ± 0. 47D. Three months postoperatively, the astigmatism was 0. 51 ± 0. 32D in group A and 0. 96 ± 0. 40D in group B. The difference between the two groups were statistically significant ( P<0. 05 ). The difference value of corned astigmatism before surgery and 1wk, 1 and 3mo after surgery had statistical significance ( P<0. 05). ln LRls group, at preoperative and postoperative time points, the average corneal astigmatism changes were also considered statistically significant difference (P<0. 05). CONCLUSlON: LRls performed during lCL surgery appeared to be an effective and safer procedure to reduce pre-existing corneal astigmatism and improve UCVA as well as the visual quality.

Objective:To study the effect of compressive stress on expression of connective tissue growth factor(CTGF) in rabbit mandibular condylar chondrocytes in vitro. Methods:CTGF mRNA were determined by semiquantitative RT-PCR in rabbit mandibular condylar chondrocytes cultured in vitro. Results:Within a certain compressive stress, CTGF mRNA were up-regulated with the increase of compressive stress. While under certain compressive stress, CTGF mRNA were gradually up-regulated following the increase of culturing time, and reaching the maximum at 2~6 h, then gradually down-regulated until at 24 h. Conclusion:Application of different compressive stresses can up-regulate the expression of CTGF mRNA in rabbit mandibular condylar chondrocytes. It may be involved in the stress -mediated mandibular condylar cartilage remodeling.

ObjectiveTo evaluate the safety and efficacy of pull through technique in the treatment of middle or low rectal cancer.MethodsRetrospective study was made on 101 patients of rectal cancer undergoing pull through resection in terms of the safety and efficacy. The technique was in brief to make coloanal anastomosis through an everted rectal stump, and pull back the proximal colon into the pelvic cavity. ResultsAll postoperative patients were followed up from 5 to 10 years. Normal or good fecal continence was achieved in 87% (88/101) of the patients, fair in 7 9%(8/101), and poor in 4 9%(5/101). Anastomotic fistula developed in 5 patients (4 9%), and local recurrence rate was 15%. The 5, and 10 year survival rates were 64% and 58%, respectively. ConclusionsColoanal anastomosis provides effective treatment for middle and low rectal cancer with a satisfactory long term survival rate and quality of life.

Objective:To detect the expression of microchromosome maintenance protein 4 (MCM4) in pancreatic ductal adenocarcinoma, and to explore the clinical prognosis of MCM4 and pancreatic ductal adenocarcinoma. To explore the possibility of MCM4 as a potential biomarker for pancreatic ductal adenocarcinoma.Methods:The mRNA level of MCM4 in pancreatic ductal adenocarcinoma and normal tissues adjacent to the cancer was analyzed by bioinformatics methods, and the relationship between its expression and the survival rate of patients with pancreatic ductal adenocarcinoma was analyzed. The clinicopathological data of 76 patients with pancreatic ductal adenocarcinoma who underwent surgical treatment were retrospectively analyzed. Immunohistochemical method was used to detect the expression level of MCM4 protein in pancreatic ductal adenocarcinoma tissue and normal tissues adjacent to the cancer, and to analyze its relationship with clinicopathological characteristics of patients with pancreatic ductal adenocarcinoma.Results:The results of bioinformatics analysis showed that MCM4 mRNA was significantly highly expressed in pancreatic ductal adenocarcinoma tissue, and was significantly correlated with the overall survival rate and disease-free survival rate of patients (all P<0.05). Immunohistochemical results showed that the expression of MCM4 in pancreatic ductal adenocarcinoma tissue was significantly higher than that in normal tissues adjacent to the cancer. The high expression of MCM4 in pancreatic ductal adenocarcinoma tissue was related to tumor size ( P=0.038), but not related to age, gender, and tumor grade (all P>0.05). Conclusions:MCM4 is highly expressed in pancreatic ductal adenocarcinoma tissues and indicates a poor prognosis, and its expression level is related to the tumor stage of pancreatic ductal adenocarcinoma. MCM4 may serve as a new potential biomarker for pancreatic ductal adenocarcinoma.
