OBJECTIVE:To observe clinical efficacy and safety of recombinant human interleukin-11 (rhIL-11) in the treat-ment of chemotherapy-induced thrombocytopenia. METHODS:86 patients with thrombocytopenia induced by chemotherapy were selected and divided into control group and observation group according to random number table,with 43 cases in each group. Con-trol group was given platelet transfusion 10 IU,once every 2-3 d;observation group was given Recombinant human IL-11 for injec-tion 25-50 μg/kg,qd. Both groups received treatment for 14 d. Clinical efficacies of 2 groups were observed as well as platelet count before and after treatment. The duration of platelet decrease and recovery,the occurrence of ADR were compared between 2 groups. RESULTS:The total effective rate of observation group was 81.40%,which was significantly higher than 62.79% of con-trol group,with statistical significance (P<0.05). There was no statistical significance in platelet count between 2 groups before treatment(P>0.05);after treatment,platelet count of 2 groups increased significantly,and the observation group was significant-ly higher than the control group,with statistical significance(P<0.05). The duration of platelet count <50×109 L-1,the time of platelet count recovering to 70×109 L-1 and 100×109 L-1 in observation group were significantly shorter than in control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CON-CLUSIONS:rhIL-11 shows good therapeutic efficacy in the treatment of chemotherapy-induced thrombocytopenia,and can signifi-cantly improve platelet count,shorten the duratione of platelet decrease and recovery with good safety.

Southern blotting with a labeled and linearized pUC 19 DNA containing a specific fragment of 0. 24 kb DNA of Plasmodium vivax asexual blood stages (kindly offered by Dr. C. Kidson )was used for further identification of blood samples showing positive reaction by dot-blot hybridization. The results showed that those with positive reaction from patients with P. vivax, with P. falciparum or with fever but with negative microscopic findings were also positive by Southern blotting. It was confirmed that some of those positive with P. falciparum were likely to infect P. vivax at the same time. So did a part of those with fever but negative in the blood films (Figs. 1,2).

Circular RNAs are a group of novel non-coding RNA molecules, which form covalently closed continuous loop structures, lacking the terminal 5′ and 3′ ends. They are abundant in eukaryotes and have recently become an increasing area of research in the field of RNA. Circular RNAs have many functions, such as abundant expression, cell- or tissue-specific expression, and high resistance to RNase-induced degradation. They are closely related to tissue development and the occurrence and development of diseases, play an important role in the pathogenesis and development of a variety of diseases, and can be used as a novel molecular marker of some diseases. Therefore, this review summarizes the latest research progress of circular RNAs in the regulation of endocrine diseases to better understand the biological mechanisms underlying endocrine diseases.

Objective To observe the influence of heat shock preconditioning on the expressions of heat shock protein(HSP)60,70 and induced nitric oxidase synthase(iNOS)in gastric mucosa of severely burned rats and investigate the protective mechanism of burn-induced acute gastric mucosal lesion.Methods Ninety-six Wistar rats were divided into two groups:burn(B)and heat shock preconditioning before burn(HB).The extent of gastric mucosal lesions(UI)was evaluated grossly and histologically.HSP70 mRNA expression was determined by RT-PCR.Immunohistochemical method was used to analyze the protein expressions of iNOS,HSP60 and HSP70.Results Rats in B group were induced conspicuous gastric mucosal lesions,while UI in HB group was significantly lower.The expressions of HSP70 and HSP60 were significantly increased and the expression of iNOS was obviously decreased in HB group as compared with B group.Conclusion Heat shock preconditioning protects against acute gastric mucosal lesion caused by burn through enhancing the expressions of induced HSPs and reducing the iNOS expression.

Summary: The effects of tanshinone Ⅱ A (TSN) on transforming growth factor β1 (TGFβ1) signal transduction in renal interstitial fibroblasts of rats were studied in order to investigate its mechanism in prevention of renal interstitial fibrosis. Rat renal fibroblasts of the line NRK/49F were cultured in vitro, stimulated with 5 ng/mL TGFβ1 and pretreated with 10-6, 10-5, 10-4 mol/L TSN respectively.The mRNA levels of fibronectin (FN) were examined by RT-PCR. The protein expression of FN and Smads was detected by Western blot. TGFβ1 induced the expression of FN mRNA and Smads in a time-dependent manner in a certain range. Compared with pre-stimulation, the FN mRNA and protein levels were increased by 1.1 times and 1.5 times respectively (P<0,01, P<0.01), and the protein expression of phosphorylated Smad2/3 (p-Smad2/3) increased by 7 times at the end of TGFβ1 stimulation (P<0.01). TSN pretreatment may down-regulate the FN and p-Smad2/3 expression in a dose-dependent manner. 10-6 mol/L TSN pretreatment had no effect on the FN and p-Smad2/3 expression (both P0.05). After pretreatment with 105 and 10-4 mol/L TSN, the FN mRNA levels were decreased by 28.1% and 43.8% respectively (P<0.05, P<0.01), the FN protein levels were decreased by 40% and 44% respectively (P<0.05, P<0.05), and the p-Smad2/3 protein expression were decreased by 40% and 65% respectively (P<0.05, P<0.01). The inhibitory effect of TSN on renal interstitial fibrosis may be related to its blocking effect on TGFβl-Smads signal pathway in renal interstitial fibroblasts.

OBJECTIVETo study the drug resistance of Acinetobacter baumannii (AB) producing VIM-2-type metallo-β-lactamase (MBL) isolated from burn patients of our ward against carbapenem antibiotics and its homology.

METHODSA total of 400 strains of AB (identified) were isolated from sputum, urine, blood, pus, and wound drainage. of burn patients hospitalized in our ward from September 2011 to March 2014. Drug resistance of the 400 strains of AB to 15 antibiotics, including compound sulfamothoxazole, aztreonam, etc. , was tested using the automatic microorganism identifying and drug sensitivity analyzer. Among the carbapenems-resistant AB isolates, modified Hodge test was applied to screen carbapenemase-producing strains. The carbapenemase genes of the carbapenemase-producing strains, and the mobile genetic elements class I-integron (Intl1) gene and conserved sequence (CS) of carbapenemase-producing strains carrying blaVIM-2 gene were determined with PCR and DNA sequencing. For carbapenemase-producing strains carrying blaVIM-2 gene, synergism test with imipenem-ethylene diamine tetraacetic acid (EDTA) and enhancement test with imipenem-EDTA and ceftazidime-EDTA were used to verify the MBL-producing status. Drug resistance of the VIM-2-type MBL-producing AB strains was analyzed. For VIM-2-type MBL-producing AB strains, plasmid conjugation experiment was used to explore the transfer of plasmid; outer membrane protein (OMP) CarO gene was detected by PCR. For VIM-2-type MBL-producing AB strains carrying CarO gene, the protein content of CarO was analyzed with sodium dodecyl sulfate polyacrylamide gel electro- phoresis. The repetitive consensus sequence of Enterobacteriaceae genome PCR (ERIC-PCR) was carried out for gene typing of VIM-2-type MBL-producing AB strains to analyze their homology.

RESULTS(1) The resistant rates of the 400 strains of AB against levofloxacin and compound sulfamethoxazole were low. A total of 381 carbapenems-resistant AB strains were screened, including 240 carbepenemase-producing strains. (2) Out of the 240 carbepenemase-producing strains, 18 strains were found to harbor the blaVIM-2 gene, accounting for 7.5%; 133 strains carried the blaTEM-1 gene, accounting for 55.42%; 195 strains carried the blaOXA23 gene, accounting for 81.25%; 188 strains carried the bla(armA) gene, accounting for 78.33%. (3) Eighteen carbepenemase-producing strains which carried the bla(VIM-2) gene were found to carry the Intl1 gene, showing the Intl1-VIM linkage. Simultaneously, Intl1 variable area CS showed diversity. (4) Eighteen carbepenemase-producing strains which carried the blaVIM-2 gene were verified to produce MBL. The resistant rates of the 18 strains of AB against compound sulfamethoxazole were the lowest, followed by levofloxacin and cefoperazone/sulbactam, and those against the other antibiotics were above 60.00%. (5) Through multiple joint tests, plasmid conjugation experiment positive transfer strain was not found in 18 VIM-2-type MBL-producing AB strains. (6) Nine out of the 18 VIM-2-type MBL-producing AB strains were found to carry CarO gene. The OMP CarO of VIM-2-type MBL-producing AB strains carrying CarO gene was lost or lowered in the protein content. (7) The 18 VIM-2-type MBL-producing AB strains were classified into 6 genotypes by the ERIC-PCR. There were respectively 6, 4, 3, and 1 stain (s) in genotypes A, B, C, and F, and there were 2 strains in genotypes D and E respectively.

CONCLUSIONSThe resistance mechanism of AB against carbapenems is mainly mediated by blaTEM-1, blaOXA-23, and bla(arma); meanwhile, VIM-2-type MBL-producing and lack or change in OMP CarO are attributable to carbapenems resistance of clinically isolated AB from burn wards, and the Intl1 gene may take a part in blaVIM-2 gene transmission.
