Results:The expanded uncertainty for the UV determination of paracetamol tablets was 1. 2%,and the content determination result was (97. 0 ± 1. 2) % (k=2). Conclusion:The main sources of uncertainty are analyzed, which can provide reliable theoretical basis for the effective control of the method.

Objective To evaluate the safety and efficacy of transcatheter closure of perimembranous ventricular septal defects(VSD) using domestic symmetric double-disk occluders.Methods From March 2003 to July 2007,689 VSD patients were treated with transcatheter intervention using domestic symmetric double-disk occluders and received clinical follow up at 1 month,3 months,6months after the procedure and annually thereafter.Complications including residual shunt,heart rhythm changing,shape of the occluder and the presence of tricuspid/aortic regurgitation were observed thoroughly.Results The overall technical success rate was 98.8%.One patient died of cerebral bleeding 7 days after intervention.One patient suffered complete A-V block and required permanent pacemaker implantation and another patient conversed to open surgery because of moderate tricuspid regurgitation.Asymmetric Amplatzer occluders were used in 6 patients but the intervention failed in 2 patients whom required an open conversion.Comorbidities such as atrial septum defect,patent foramen ovale were treated concomitantly.No other complications were observed during the follow-up period.Conclusion Complication associated with transcatheter closure of perimembranous VSD using domestic symmetric double-disk occluders was relatively low.The procedure was safe and applicable.Meanwhile,it is necessary to stick to the procedural indications and avoid complications such as tricuspid regurgitation etc.

Humidificait on by artificial means must be provided when the upper airway is bypassed during mechanical ventilation.Enough humidification is very important during mechanical ventilation.Heated humidification( HH) and heta and moisture exchanger( HME) are the most commonly used types of artificial humidification in this situation.In this article, their advantages and disadvantages are itn roduced.HH na d HME are compared in humidification performance,effect no ventilator mechanics and association with venti-lation associated pneumonia.Depending on the clinical scenario, humidifier is reasonably selected, and the selection may changeo ver time according the treatment effect.

Objective:To investigate the possibility of miR-125b in serum as a novel tumor marker for primary hepatocellular car-cinoma (HCC) and the diagnosis value of combined detection of miR-125b and alpha-fetoprotein (AFP) for HCC. Methods:We detected serum miR-125b expression of 65 cases of HCC patients and 30 cases of healthy controls by real-time quantitative PCR. Moreover, we analyzed the significance of miR-125b and explored the relationship between miR-125b and clinical pathological factors. Results:The level of miRNA-125b was down regulated in serum of HCC patients compared with healthy controls which showed significant differences (P<0.05). Furthermore, the expression of miRNA-125b has no distinct correlation with sex, age, HbsAg, AFP, ALT andα-GGT, which had no significant differences (P>0.05). The expression level of miRNA-125b correlated the difference with liver Cirrhosis, tumor size and tumor node metastasis (TNM) stages, which were considered significant differences (P<0.05). The receiver operating characteristic (ROC) curve analysis of serum miR-125b for the diagnosis of HCC yielded AUC of 0.917(95%CI:0.851~0.960, P<0.001)with 85.9%sensitivity and 93.5%specificity. The ROC curve analysis of combined miR-125b and AFP for HCC detection yielded AUC of 0.951(95%CI:0.894~0.982, P<0.001)with 92.9%sensitivity and 93.5%specificity. The ROC curve analysis of serum miR-125b as biomarkers for the group (AFP<20μg/L) of HCC yielded AUC of 0.889(95%CI:0.776~0.957, P<0.001)with 84.0%sensitivity and 87.1%specificity. Conclusion:Serum miRNA-125b combined with AFP has considerable clinical value for the early diagnosis of primary HCC.

Background:As postoperative intra-abdominal septic complications( IASCs)in Crohn’s disease( CD)are difficult to manage,it is of great importance to prevent this condition in CD patients after surgery. Till now,there are no large sample studies on risk factors for postoperative IASCs in CD in China. Aims:To determine the risk factors for postoperative IASCs in CD for guiding the formulation of preventive strategies. Methods:This retrospective study was based on a computerized database of CD patients who had undergone surgery for CD complications between 1999 and 2014 at Nanjing General Hospital of Nanjing Military Command,PLA. Patients were divided into IASCs group and non-IASCs group. Thirty potential variables were selected,and both univariate and multivariate( Logistic regression)analyses were performed to identify the risk factors for IASCs after surgery. Results:Seven hundred and sixteen operations were reviewed,and IASCs occurred in 41 cases(5. 7%). By univariate and multivariate analyses,IASCs were significantly associated with one stage anastomosis(OR=1. 656,95% CI:1261-3. 279),preoperative low albumin level( <30 g/L)(OR=1. 457,95% CI:1. 152-2. 368),preoperative high CRP level( >10 mg/L)(OR=8. 641,95% CI:3. 376-16. 364),preoperative steroids use ≥3 months(OR=3. 785,95% CI:1. 237-4. 671)and presence of intra-abdominal abscess or infection at the time of surgery(OR=1. 784,95% CI:1. 155-3. 826). However,enterostomy(OR =0. 125,95% CI:0. 062-0. 561)and preoperative enteral nutrition ≥ 1 month( OR =0. 147,95% CI:0. 078-0. 781 ) were found to be the independent protective factors. Conclusions:Malnutrition,active CD and preoperative long-term steroids use increase the risk of postoperative IASCs in CD. Patients with these risk factors should not receive immediate surgery. If surgery is inevitable, enterostomy instead of resection and anastomosis should be the first choice. Preoperative enteral nutrition is helpful for reducing the occurrence of IASCs after surgery.

Objective To investigate toe-brachial index ( TBI) in the diagnosis of peripheral artery disease ( PAD) and its risk factors in the patients with type 2 diabetes.Methods TBI was examined in the 238 patients with type 2 diabetes.The patients were divided into the group with low TBI ( TBI≤0.7 ) and the group with normal ABI ( TBI>0.7 ) .The two groups were compared for clinical parameters.Results Thirty two patients (13.4%)with abnormal ABI (TBI≤0.7) showed older age [(63.8 ±9.9) yrs vs (54.9 ±10.8) yrs, P =0.000] , lower diastolic blood pressure [(70.5 ±6.9) mmHg vs (74.9 ±9.1) mmHg, P =0.003], more frequency of hypertension (56.3%vs 38.3%, P =0.043), coronary artery heart disease (28.7%vs 10.7%, P =0.020) and cere-bral vascular disease (15.6%vs 4.4%, P =0.025).Step-wise analysis screened that age and diastolic blood pressure were the inde-pendent risk factors for TBI .Conclusions Aging and hypertension were the risk factors in the patients with abnormal TBI in type 2 di-abetes.TBI was an easy and economical method for diagnosing PAD in patients with type 2 diabetes.

OBJECTIVETo observe the effect of Ganoderma lucidum decoction in treating Russula subnigricans poisoning (RSP) patients.

METHODSThe 14 patients of RSP in the treated group were treated with GLD (GLD, one dose was prepared by 100 g of Ganoderma lucidum decocted with water to 600 ml), on the base of conventional treatment, and 11 patients received conventional therapy in the previous year were taken as control. The clinical efficacy and parameters in them were compared, including the urine N-acetyl-D-glucosaminidase (NAG, which reflects the injury of kidney), the red blood cell and protein in urine, the alanine transaminase (ALT, which reflects the injury of liver), and the aspartate aminotransferase (AST, which reflects the injury of heart).

RESULTSA better clinical cure-markedly improving rate was showed in the treated group as compared with the control group, P < 0.01. In the treated group, red blood cell in urine disappeared after 24 hrs treatment in the majority of patients, urinary protein reduced obviously and the other three parameters reached the peak at the 3rd day then lowered gradually. In the control group, all the parameters increased continuously. Comparison between the parameters at corresponding time in the two groups showed significant difference (P < 0.01), those in the treated group were markedly lower than those in the control group respectively.

CONCLUSIONGLD has good effect in treating RSP, could obviously lower the fatat rate of RSP.
