OBJECTIVE To study effective and convenient method for paraffin oil sterilization.METHODS By using carrier qualitative germicidal test,to compare pressure steam sterilization,dry heat sterilization and cobalt-60(gamma)-ray radiation sterilization to test the sterilizing effect and operating procedure.RESULTS Pressure steam sterilization was unable to achieve 100% sterilizing effect,whether we extended the time or use the intermittent(sterilization).After dry heat or radiation sterilization processes,no microorganism was found.CONCLUSIONS Effect of sterilization with dry heat or radiation sterilization is trustable,but its packing,operation and equipment are requested strictly,and pressure steam sterilization may be not good for paraffin oil.

Objective To select microRNAs (miRNA) associated with human cutaneous malignant melanoma (MM). Methods Total RNA was extracted from 6 tissue samples of MM and 9 human control samples of pigmented nevi, and small RNAs of less than 200 bp were enriched, miRNA microarray was used to select differentially expressed miRNAs between tissue samples of MM and pigmented nevi from 468 candi-dates. The expression of differentially expressed miRNAs was confirmed by fluorescence based real-time quan-titative PCR (qPCR) in all of these samples. Those miRNAs that were identified as differentially expressed with both miRNA microarray and qPCR were considered as significant miRNAs. Results Between the tissue samples of MM and pigmented nevi, 12.18% to 86.33% of miRNAs differentially expressed by more than 2 folds, 1.28% to 19.02% by more than 5 folds, and 0.43% to 5.34% by more than 10 folds. The expression of miRNA-21 was obviously up-regulated, while that of miRNA-320 and miRNA-494 was down-regulated in the MM samples. Conclusion There is an increase in the expression of homo sapiens miRNA-21 but a decrease in that of miRNA-320 and miRNA-494 in MM tissues.

Methods Wound care team gave the treatment and nursing to 7 cases of refractory wounds in the department of orthopedics, used the new type of wound dressings. Results Among 7 cases, 5 cases were cured and discharged. The granulation growth of the wound was good, and the wound was healed after the transfer surgery of the joint flap. One patient had reached the healing rate of 90% after discharging, and recovered after being followed up for 22 days. Conclusions The correct assessment of the wound, reasonable choice of the new dressing, a good job of anti-infection treatment and the skin protection around the wound can effectively promote healing of the refractory wound after fracture, reduce the cost of health care, and bring the satisfaction to the patients and their families.

Objective To compare three methods for the extraction of mycobacterial DNA.Methods Two commercial DNA extraction kits and an ordinary freeze-thawing method were used to extract DNA from the pure suspensions of three species of Mycobacteria (M.tuberculosis,M.leprae and M.smegmatis) at different densities (1 × 10 to 1 × 105 cells/ml),simulated clinical specimens containing different concentrations of mycobacterial cells (1 × 10 to 1 × 104 cells/ml).The purity and concentration of the extracted DNA were evaluated.Then,PCR was performed to amplify the 16S rRNA region of Mycobacteria.The performance of the three methods was compared by the purity and concentration of extracted DNA as well as the results of PCR.Further more,76 clinical skin specimens suspected to be infected with Mycobacteria were used to further validate the performance of these methods.Results All the extracted DNA samples could be detected by PCR.The highest purity of DNA was obtained by the kit A,followed sequentially by the freeze-thawing method and the kit B.When pure suspensions were used,the detection limit was consistently 1 × 102 cells/ml for all the three methods.With simulated specimens,the detection rate was consistently 100％ for all the three methods at the concentration of 1 × 103 cells/ml,60％ (12/20),55％ (11/20) and 55％ (11/20) for the kit A,kit B and freeze-thawing method respectively at the concentration of 1 × 102 cells/ml.The analysis of clinical specimens showed that the kit B could be used to extract DNA from paraffin-embedded specimens,with the detection rate similar to that of kit A and freeze-thawing method.Conclusions The kit A could rapidly yield high-quality genomic DNA of Mycobacteria by repeated cleaning of columns,and may serve as the optimal method for scientific and clinical studies,and the kit B is suitable for extracting mycobacterial DNA from fresh tissue specimens besides paraffin-embedded specimens.

BACKGROUND:Previous studies have demonstrated that normal rat liver homogenate supernatant can induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels with partial hepatocyte functions. However, whether fibrotic liver homogenate supernatant can work or how the inducing effect is remains unclear. OBJECTIVE:To investigate the differentiation potential of human umbilical cord mesenchymal stem cels into hepatocytes under the normal liver and fibrotic liver microenvironment in vitro. METHODS:Liver fibrosis was induced in the SD rats by repeated intraperitoneal injections of 3% thioacetamide at a dose of 200 mg/kg body mass, twice a week for 4 weeks, and then fibrotic liver tissues and normal liver tissues were used to prepare liver homogenate supernatants. Passage 3 human umbilical cord mesenchymal stem cels were used and divided into standard control group (cels were cultured in DMEM/F12 with 10% fetal bovine serum), fibrotic liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 50 g/L fibrotic liver homogenate supernatants), normal liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 100 g/L normal liver homogenate supernatants). The morphological changes of the cels in each group were recorded under inverted microscope; the protein levels of CK18, AFP, CYP3A4, CYP2E1, CYP2D6 and TPH2 were evaluated using western blot assay. Furthermore, the concentration of albumin in the cels was measured. RESULTS AND CONCLUSION:After a 7-day inducement, the stem cels in liver homogenate supernatants groups lost their fusiform shape and changed into hepatocyte-like cels with the morphous of round shape. Compared with the standard control group, the hepatocyte-like cels in the two liver homogenate supernatants groups exhibited human hepatocyte biomarkers, CK18 and AFP. The standard control group cels could express a little amount of CYP2E1, while cels in the two liver homogenate supernatants groups could express CYP3A4, CYP2E1, CYP2D6, TPH2. Compared with the standard control group, the expression level of CYP2E1 in the two liver homogenate supernatants groups increased significantly (P < 0.01), and however, the relative levels of CYP3A4, CYP2E1, CYP2D6, TPH2 in the two liver homogenate supernatants groups showed no statistical significance (P > 0.05). At the same time, compared with the standard control group, the concentration of albumin in the two liver homogenate supernatants groups markedly increased (P < 0.01), but there was no difference between the two liver homogenate supernatants groups (P > 0.05). Experimental findings demonstrated that both of normal liver tissue and fibrotic liver tissue microenvironments could induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels. To achieve the same effect, compared with normal liver tissue, fibrotic liver tissue required lower concentrations, suggesting that fibrotic liver tissue microenvironment may be more conducive to differentiation of umbilical cord mesenchymal stem cels into hepatocytes.

OBJECTIVE To investigate the changes in serum HBV-DNA level in HBsAg positive patients before and after operation and their infectious risk in hospital.METHODS HBV markers(HBV-M) in serum was detected in 58 HBsAg positive patients by time-resolved fluoroimmunometric assay before operation.HBV-DNA level in serum of them before operation and at 3rd,and 7th day after operation was detected by real time fluorescent quantitative polymerase chain reaction.We also detected HBV-DNA in gastric drainage juice and abdominal drainage after operation.RESULTS HBV-DNA was detected in 27 of 58 HBsAg positive patients' serum,the positive rate was 46.1%.After operation,serum HBV-DNA was increased remarkably at 3rd and 7th day compared with before operation in these patients respectively(P

Objective To investigate the expression level of CD226 mRNA in the peripheral blood mononuclear cells (PBMCs) of patients with systemic lupus erythematosus (SLE) and explore the relation between the gene expression and disease activity, and the relation between the gene expression and Gly307Ser polymorphism of CD226 was also examined. Methods CD226 gene was measured with real-time polymerase chain reaction (qRT- PCR) in PBMCs. The expression levels of CD226 gene in PBMCs were compared between 90 SLE patients and 30 healthy individuals. One-way ANOVA and pearson correlation were used for statistical analysis. Results The expression level of CD226 in the PBMCs of SLE patients (6.8±1.1) was significantly decreased compared to healthy individuals (26.5±6.7) (P＜0.01), while there was no association between mRNA level and genotype (P＞0.05). No correlation between ESR, CRP, ANA, SLEDAI scores, C3 and the expression level of CD226 gene was discovered. Conclusion In Hubei Chinese Han population, CD226-Gly307Ser locus is associated with the development of SLE, while T allele does not impact the expression of CD226 gene, thus the role of CD226 gene in autoimmune diseases should be explored in the future.
