In the process of acid hydrolysis of medical absorbent cotton, we have discovered that some of the domestic manufactured medical absorbent cotton is mixed with wasted non-cotton chemical fiber. If the cotton is used in medical treatments, the chemical fiber will cause irritation, allergy and inflammation, so it's very harmful. But the non-cotton fiber content is not stipulated in the standard of YY0330-2002, and no testing method for it is available. In this paper we discuss the existent quality problems, the control and the test method for non-cotton chemical fiber in medical absorbent cotton.

The positive ratio is 74 percent using the plate anaerobe culturing device made by author, higher than using common anaerobic box and anaerobic jar.

Using 16S rDNA clone library method, the bacteria composition of the Organic Matter-decomposing Inoculants A and B were investigated. The results indicated that: Sample A was clustered into 14 taxonomic operational units (OTUs),the dominant communities are Weissella confuse, Bacillus subtilis and Bacillus pumilus, which accounted for 28.6%,30.4% and 23.2%;Sample B was clustered into 43 OTUs,the dominant communities are Lactobacillus buchneri, Lactobacillus farciminis and Lactobacillus acetotolerans, which accounted for 18.03%,18.86% and 13.12%, respectively. The results had much difference from the samples' labels:there were not bacteria in the lable of sample A and only Bacillus pumilus was the same with the lable of sample B.This study showed that 16S rDNA clone library method has nicer application perspectives in analying the bacteria of microbial inoculant and its quality control.

120 strains of endophytic bacteria identified by ERIC-PCR were isolated from wild and cultivated Glycyrrhiza uralensis plants which collected from Erdos Innermongolia province.The identified results indicated that Glycyrrhiza uralensis plants has plenty of endophytic bacterium in density and population,and the density is higher in root and leave than in stem.Partial sequence analysis of 16S rDNA gene of 82 strains indicated that these strains were in a high similarity with 19 known genus which belong to?、?、 ?-Proteobacteria、Firmicutes and Actinobacteria.The dominant genus were Bacillus sp.,Pseudomonas sp., Pantoea sp.and Serratia sp..

Objective To evaluate the theraputic effect of transcatheter arterial chemoembolization (TACE)for hepatocellular carcinoma with tumor thrombosis of portal vein.Methods One hundred and six patients of hepatocellular carcinoma with tumor thrombosis of portal vein under treament of TACE were observed before and after the procedure.Results After TACE tumor size reduced＞50% in 23 patients,＜50% in 25, no significant change in 44.The size of tumor enlarged in 12.The disappearance of portal vein tumor thrombosis accessed in 14,with reduction in 39,and no significant change in 51.Two patients died within one week.Conclusion TACE provides good therapeutic effect on hepatocellular carcinoma with tumor thrombosis of portal vein.

98 endophytic bacteria strains were isolated from different internal tissues of Glycyrrhiza uralensis plants collected from Innermongolia region. Results indicated that the population densities of endophytic bacteria ranged from 5.0?104cfu/g～2.9?107cfu/g fresh weight although it varied depending on tissue of the plant. Among these strains, Bacillus sp. was the most prevalent endophytic bacterium, which was amount to 30%.Of the 98 isolates, 6 strains exhibited extensive antagonistic activities against pathogenic bacteria. Characterization showed that these bacteria were Bacillus atrophaeus、Paenibacillus polymyxa、Bacillus subtilis、Paenibacillus ehimensis. This study indicated that selected 6 endophytic bacteria strains have potential for biological control of plant disease.

Objective To detect the mutations of ATP2C1 gene in patients with Hailey-Hailey dis- ease (HHD).Methods PCR and direct sequencing were performed in 17 patients and 120 healthy controls to screen the mutations in the exons of ATP2C1 gene.Results Eight mutations were identified in nine probands, including three deletion mutations (nt1464-1487 del/nt1462-1485del,1523delAT,2375delTTGT),three splice site mutations (360—2A→G,1415—2A→T,2243+2T→C) and two missence mutations (C920T and G1942T).None of the above mutations was found in the controls.Conclusion Eight specific novel mutations were identified in nine probands of HHD,which could be causative factors of the disease.

OBJECTIVETo explore the clinical value of ultrasonic surface localization in internal jugular vein catheterization.

METHODSTotally 150 patients with American Society of Anesthesiologists physical status I -III who were planning to receive elective surgeries were randomized into anatomical landmark group, ultrasonic surface positioning group, and ultrasound-guided group using computed random table, with 50 cases in each group. The right internal jugular vein catheterization was performed after tracheal intubation. In the anatomic landmark group, patients were punctured using surface marks through central approach. In ultrasonic surface positioning group and ultrasound-guided group, patients were punctured with ultrasonic localization and guidance through central approach. The relationship between internal jugular vein and carotid artery, the position of the needle into the vein, the success rate of puncture, the change times of puncture point, and the complications were recorded.

RESULTSUltrasound scan revealed that the relationship between the right internal jugular vein and the right common carotid artery could be divided into three types: parallel (12.7%), partial overlapping (69.3%), and complete overlapping (18.0%). The average "safety distance" of jugular vein puncture was (1.15 +/- 0.47) cm. The success rate of the first puncture attempt in ultrasonic surface positioning group and ultrasound-guided group were 78.0% and 82.0%, respectively, which was significantly higher than that in anatomic landmark group (22.0%) (P < 0.05), whereas the complication incidence in anatomic landmark group (12.0%) were significantly higher than those in ultrasonic surface positioning group (0) and ultrasound-guided group (0) (P < 0.05).

CONCLUSIONSUltrasonic surface positioning applied during internal jugular vein catheterization is helpful to reveal the inner diameters as well as the origin and course of arteries and veins in the puncture and identify the abnormalities as early as possible. As a simple support technique for internal jugular vein puncture, it is suitable for clinical application.
