Objective:To evaluate the quality of carbazochrome sodium sulfonate Injection from different manufacturers, analyze the existing problems and provide the reference for the improvement of clinical medication safety. Methods:Statutory testing methods and the exploratory research methods were used to examine the samples, and the quality status of carbazochrome sodium sulfonate Injec-tion was evaluated according to the results. Results:Totally 89 batches of the samples were tested by the current standard. The quali-fied rate was 97. 8%, and the two batches of unqualified samples were carbazochrome sodium sulfonate and sodium chloride Injection with unqualified insoluble particles. Overall, the quality risk of carbazochrome sodium sulfonate for injection was low, and the safety of carbazochrome sodium sulfonate and sodium chloride Injection needed further research. Conclusion:The quality of carbazochrome so-dium sulfonate Injection basically meets the current standard, and the exploratory research suggests that the current standard is imper-fect. It is urgent to improve the related substance detection in the standard and determine the reasonable limits for the degradation im-purities and the other impurities. The clinical medication safety of carbazochrome sodium sulfonate and sodium chloride Injection needs further research.

BACKGROUND: Autoreactive T cells are a group of specialized cells that exert a peripheral immunosuppressive effectthrough certain mechanisms ensuring self-tolerance within the adaptive immune system. The discovery of the latestsurface markers for natural CD4+CD25+ regulatory T cells has re-emphasized the concept of peripheral regulation orsuppression of T cells. Several groups have begun to investigate the role of regulatory T cells in animal models ofallogeneic hematopoietic stem cell transplantation.OBJECTIVE: To review the recent results regarding protection from graft-versus-host disease by adoptively transferredCD4+ CD25+ regulatory T cells in mice and to discuss the latest findings from clinical studies on hematopoietic stem celltransplantation.METHODS: We retrieved CNKI, PubMed and Medline databases for articles concerning CD4+CD25+ regulatory T cellsand graft-versus-host disease published from 2000 to 2015. According to inclusion and exclusion criteria, 46 paperswere included in result analysis.RESULTS AND CONCLUSION: CD4+CD25+ regulatory T cells expressing the transcriptional repressor FOXP3 mediateimmunoregulatory functions and are critical for the prevention of autoimmune diseases. As peripheral tolerance inductionis a prerequisite for successful allogeneic hematopoietic stem cell transplantation, the role of CD4+CD25+ regulatory Tcells in transplantation models and clinical trials is now under investigation in many laboratories. CD4+CD25+ regulatoryT cells play an important role in the development of graft-versus-host disease after allogeneic hematopoietic stem celltransplantation. CD4+CD25+ regulatory T cells not only effectively prevent and treat graft-versus-host disease but alsoretain graft-versus-leukemia effect.

The combination of PBL method with traditional teaching methods achieved a good effect.

BACKGROUND:Current research has shown that many cellgrowth factors can promote the proliferation and differentiation of epiphysis stem cells, and this regulation is closely related to Sox-9.
OBJECTIVE:To investigate the effects of smal interfering RNA-induced specific silence of Sox-9 gene on the proliferation and apoptosis of epiphysis stem cells.
METHODS:Epiphysis stem cells were isolated from the ring of La Croix with enzyme digestion and purified with magnetic activated cellsorting, identified by immunocytochemistry assay. The cells in good conditions were selected to be transfected by Sox-9 silenced by smal interfering RNA with fluorescent marker, and then were observed under the fluorescent microscope to check the transfection efficiency. Next step, epiphysis stem cells were divided into 2 groups:group one was cultured normal y as control group;group two was transfected by Sox-9 silenced by smal interfering RNA through LipofectamineTM 2000 as experimental group.
RESULTS AND CONCLUSION:The primary epiphysis stem cells were separated and purified, which were of stable growth and tightly attachment. The results of immunohistochemistry and immunofluorescence showed the epiphysis stem cells expressed cel-specific markers, fibroblast growth factor receptor 3. After transfection, reverse transcription-PCR results showed that Sox-9 gene expression in epiphysis stem cellwas inhibited specifical y;3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide results showed that cellproliferation in experimental group decreased significantly compared with the control group (P<0.05), and the cellapoptosis detected by flow cytometry showed that the experimental group increased as compared with the control group (P<0.05). Sox-9 gene plays an important role in regulating the proliferation and apoptosis of rat epiphysis stem cells.

OBJECTIVE:To observe the clinical efficacy and safety of different doses of atorvastatin in the treatment of chron-ic subdural hematoma(CSDH). METHODS:One hundred and tweaty-eighie CSDH patients selected from our hospital during Jun. 2013-May 2015 were divided into observation group(n=62)and control group(n=66)in accordance with random number table. Both groups were given conventional treatment of brain cell nutrition. Control group received Atorvastatin tablet 20 mg,po,qd;observation group received Atorvastatin tablet 40 mg,po,qd. Both groups were treated for 6 months. Clinical efficacy,CSS and ADL score,hematoma volume,the levels of serum inflammatory factors (hs-CRP,MMP-9,IL-6,TNF-α) were observed in 2 groups. ADR was recorded during treatment and recurrence rate was also recorded. RESULTS:2 patients withdrew from observa-tion group and 6 from control group. Finally,120 patients met the criteria were included,with 60 cases in each group. Total re-sponse rate of observation group(88.3%)was significantly better than that of control group(73.3%),with statistical significance (P<0.05). After 1,3,6 months of treatment,CSS score,hematoma volume,the serum levels of hs-CRP,MMP-9,IL-6 and TNF-α in 2 groups were significantly decreased,while ADL score was increased significantly;the improvement of above indexes in observation group was significantly better 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). The recurrence rate of control group(13.3%)was significantly higher than that of observation group(3.3%),with statistical significance(P<0.05). CONCLUSIONS:Daily dose of shows ator-vastatin 40 mg better therapeutic efficacy and lower recurrence rate in the treatment of CSDH with good safety.

The hemolysin production of 19 strains of Streptococcus spp. isolated from pigs in the Jiangsu and Shanghai regions in recent years were examined. Eight isolates of Streptococcus suis type 2 from Jiangsu showed weak hemolysis on blood agar, but a stronger reaction in Todd-Hewitt broth(THB). The hemolysin belonged to the group of thiol-activated hemolysins. Nine strains of Streptoccus equi subsp. zooepidemicus showed strong hemolysis on blood agar and in THB containing 5% new-born calf serum, but no hemolysis in THB alone. This hemolysin was similar to streptolysin S(SLS). Another two isolates were atypical members of Lancefield group C Streptococcus and showed strong hemolysis on blood agar and in THB with 5% new-born calf serum, but the hemolysin was unlike either streptolysin O or SLS.
