[ Objective ] To explore the related factors of colorectal polyps. [ Methods ] Participants were divided into polyps group and control group according to colonoscopy.The possible risk factors were investigated by questionnaire.Logistic regression analysis was conducted in order to explore the related factors of colorectal polyps. [ Results] A total of 252 participants (154 in polyps group, 98 in control group) were enrolled in the current study.Multivariate Logistic regression analysis showed that those with higher odds ratio of colorectal polyps were among male ( OR: 2.65, 95% CI: 1.17 -6.00) and obesity(OR:4.80,95%CI:1.16 -9.94), among those with family history of colorectal polyps ( OR:10.19, 95%CI:1.19-17.26), and those with high proportion of fat intake(OR:3.24, 95%CI:1.46-7.20). [ Conclusion] Male, obesity, family history of colorectal polyps and high proportion of fat intake are the related factors of colorectal polyps. And investigation by related factors questionnaire facilitates the targeted screening of colorectal tumors.

OBJECTIVETo study the impact of gonadotropin-releasing hormone analogs (GnRHa) on body mass index (BMI) in girls with idiopathic central precocious puberty (ICPP).
METHODSOne hundred and thirty-four girls with ICPP were enrolled. Fifty-seven out of the 134 girls were treated with GnRHa for 1.69±0.43 years. The height, weight, bone age and BMI were measured before treatment, at the end of the treatment and after reaching near adult height and compared with those in the untreated 77 girls.
RESULTSThe adult predicted height standard deviation score (SDS) at the end of treatment was significantly higher than that before treatment (P<0.01) and was similar to the target height SDS in the GnRHa treatment group (P>0.05). With GnRHa treatment, the near-adult height SDS was higher than the target height SDS (P<0.01). At the end of treatment, the BMI SDS slightly increased compared with pretreatment level (P>0.05). A significant reduction in the BMI was observed when reaching the near-adult height in the GnRHa treatment group compared to the level of pretreatment and the untreated group (P<0.01). However, the BMI in the GnRHa treatment group before treatment, at the end of the treatment and after reaching near adult height remained in the normal range (±1 SD).
CONCLUSIONSGnRHa may improve the final height in girls with ICPP. The alterations of BMI after GnRHa therapy fluctuate in a normal range.

BACKGROUNDRadiofrequency catheter ablation (RFCA) has been established as an effective and curative therapy for ventricular tachycardia (VT) and severely symptomatic premature ventricular contraction (PVC) from the outflow tract in structurally normal hearts. This study aimed to investigate electrophysiologic characteristics and effects of RFCA for patients with idiopathic VT and symptomatic PVC originating from the valve annulus.
METHODSCharacteristics of body surface electrocardiogram (ECG) and endocardiogram in a successful RFCA target were analyzed in 16 patients with idiopathic VT and symptomatic PVC originating from the valve annulus. Additionally, the ECG characteristics of VT or PVC were compared with those of manifest Wolff-Parkinson-White (WPW) syndrome originating from the same site of origin in 15 patients.
RESULTSThirteen patients were successful, 2 recurrent and 1 failed. The recurrent cases underwent successful ablation the second time guided by the Ensite 3000 mapping system. In all patients with the WPW syndrome, the characteristics of QRS morphology were well matched with those of the VT and PVC that originated from corresponding sites of origin.
CONCLUSIONSRFCA is an effective curative therapy for VT and symptomatic PVC originating from the valve annulus. There are specific characteristics in ECG and the ablation site could be located by means of the WPW syndrome accessory pathway's algorithm.

Chinese Journal of Contemporary Pediatrics 2012;14(10):733-736
OBJECTIVETo investigate the high-risk factors for parenteral nutrition-associated cholestasis (PNAC), which is the most common complication of parenteral nutrition for infants, in very low birth weight infants (VLBWIs).
METHODSRetrospective analysis was performed on the clinical and laboratory data of 204 VLBWIs who received parenteral nutrition for over 2 weeks in the neonatal intensive care unit from August 2006 to December 2011. The infants'liver function was evaluated periodically before and after Parenteral nutrition. Univariate analysis and multivariate analysis were performed in the observation (PNAC) and control (without PNAC) groups.
RESULTSPNAC occurred in 46 (22.5%) of the 204 VLBWIs. Univariate analysis showed that continuous positive airway pressure (CPAP) ventilation, respiration failure, respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP) were significantly increased in the observation group compared with the control group. The observation group had lower birth weights, longer duration of ventilation, later breast feeding beginning, longer duration of fasting, longer duration of parenteral nutrition, and higher cumulated amino acid and lipid emulsion intake. Logistic regression analysis revealed that duration of fasting was a high-risk factor for PNAC (OR=1.115, 95%CI: 1.031-1.207).
CONCLUSIONSMany risk factors are associated with PNAC. Early enteral nutrition and short duration of parenteral nutrition are helpful in preventing the incidence of PNAC in VLBWIs.

OBJECTIVETo investigate the exposure levels of carbon disulfide (CS(2)) for a chemical fiber industry.
METHODSThe concentration of CS(2) was monitored in representative workshops and types of work, and the datas of that over the years were collected.
RESULTSThe short-term exposure concentration of CS(2) about 80% of the type of work was less than or equal to 10 mg/m(3), which of more than 90% was less than or equal to 20 mg/m(3). The time weighted average concentration of CS(2) about 70% of the type of work was less than or equal to 5 mg/m(3), which of more than 90% was less than or equal to 10 mg/m(3). The short-term exposure concentration of CS(2) which was more than 15 mg/m(3) or the time weighted average concentration of CS(2) which was more than 30 mg/m(3) was only for little type of work.
CONCLUSIONThe concentration of CS(2) for the most type of work was lower, but there were still a number of types of work exposuring the higher concentration, which exceed the national occupational exposure limits.

ObjectiveTo investigate the methods and effects on the mobilization and collection of peripheral hematopoietic stem cells.MethodsPeripheral hematopoietic stem cells of 198 cases of healthy donors were selected and mobilized by subcutaneous recombinant human granulocyte colony stimulating factor (rhG-CSF) by (5-10) μg·kg-1 ·d-1 and collected on the 5th day. The effects of gender, height, age and WBC count of donors on mobilization and collection were analyzed. ResultsAll the peripheral hematopoietic stem cells of donors were successfully mobilized.The average counts of mononuclear cells(MNC)and CD34+ cells were (4.19±1.96)×108/kg and (2.98±1.40)×106/kg, respectively, which had no correlation with gender, height and age.The counts of MNC and CD34+ cells collected were positively correlated with the WBC count of peripheral blood (r =0.9201, P =0.0035; r =0.8420, P =0.0149). The donors with WBC ≥20.0×109/L had moresignificant effect than thoseWBC<20.0×109/L (F =4.688, P =0.0013; F =4.622, P =0.0006). Conclusion The WBC count of peripheral blood from healthy donors is a simple and feasible indicator to predict the quantity of CD34+ cells.
