A moderately thermoacidophilic iron-oxidizing bacterium,designated as strain MLY,was isolated from a coal spoil heap in China.The optimum of temperature for growth is 50℃～54℃.The optimum of pH is 1.2～1.4.The strain MLY is facultative autotroph and grows heterotrophically on yeast extract.It is able to oxidize ferrous iron(Fe 2+ ),pyrite(FeS 2),and elemental sulfur(S 0) autotrophically and mixotrophically in the presence of yeast extract.Autotrophic oxidation of elemental sulfur is relative weak.The comparison of ferrous iron and pyrite oxidation between strain MLY and A10 Thiobacillus ferrooxidans,strain indicated that MLY is one time faster than A10.

Objective To explore the methods for early diagnosis and treatment of blunt pancreatic injury.Methods The clinical data of 32 patients with blunt pancreatic injury treated in our hospital from Janurery 2004 to Janurery 2009 were retrospectively analyzed.Results The conformity diagnosis rate of CT was 79.3%.Four cases received nonoperative treatment including 3 cases of grade I and 1 of grade II injury.A total of 28 cases with blunt pancreatic injury underwent operation: 5 grade I and 7 grade II cases underwent debridement and drainage;among the patients with grade Ⅲ injury,4 underwent distal pancreatectomy in combination with splenectomy,and 2 pancreatectomy with spleen preservation;amongst the 5 patients with grade Ⅳ injury,4 underwent Roux-en-Y pancreaticojejunostomy and 1 underwent distal pancreatectomy in combination with splenectomy;of the 5 patients with grade Ⅴ injury,1 case was operated on using duodenorrhaphy and diverticulization,2 underwent the Whipple′s procedare and 2 had damage control surgery.Three patients died of multiple organ failure,and complications occurred in 19(76.0%).Pancreatic fistula and pancreatic pseudocysts were the main complications.Conclusions In the absence of major pancreatic ductal injury,and the clinical conditions were stable,pancreatic injuries can be treated with nonoperative management.Operative treatment is suitable for severe blunt pancreatic injury.Appropriate operation,based on patient condition and the classification of pancrecatic trauma,is the key to increase the cure rate and decrease mortality rate.

AIM:To explore the clinical value of combined detection of C-reactive protein ( CRP ) , erythrocyte sedimentation rate ( ESR) and white blood cell ( WBC) count in patients with ocular syphilis.
METHODS:Dates of CRP, ESR, WBC, TPPA and RPR of 51 ophthalmopathy patients caused by syphilis and 50 normal control from Jan. 2012 to Dec. 2015 in eye hospital were recruited and analyzed statistically.
RESULTS:The positive rates of CRP, ESR and WBC of oculopathy patients were 16%, 18% and 39%, respectively, which were higher than those in the control group. In patients group, the positive rate of ESR was higher than CRP and WBC. There were no obvious relationships between RPR titers and positive ratios of CRP, WBC and ESR.
CONCLUSION: The blood level of CRP, WBC and ESR may have certain help in estimating and monitoring condition of patients with ocular syphilis.

Background Choroidal melanoma(CM)is a common form of primary ocular cancer in adults.It is reported that indomethacin has inhibitory effect on many tumor in vitro and in vivo,but whether it can inhibit the growth of CM has not been published. Objective This study was to investigate the anti-tumor activity of indomethacin on the growth of human CM OCM-1 cell xenografts in nude mice. Methods OCM-1 cells were subcutaneously implanted on 24 SPF female BALB/C.nu/nu nude mice to establish ectopic models of human CM.The nude mice with the tumor 5 mm were randomly divided into 4 groups:untreated group,normal saline solution(NS) group,indomethacin 1 ms/kg group,indomethacin 2 ms/kg group.The 1 mS/kg or 2 ms/kg indomethacin was intraperitoneally injected for 14 consecutive days in indomethacin 1 ms/kg group and indomethacin 2 me/kg group respectively.and 0.2 ml of 2%NS-DMSO was used at a same way in the NS group.No any agent was used as the untreated group.The volume and weight of implanted tumor as well as inhibitory rates of indomethaein on tumor were calculated.The expression of ki67 and survivin proteins were measured with immunohistochemistry,and the expression of survivin mRNA in CM was assessed by RT-PCR. ResuIts The tumor of indomethacin treatment group was reduced in volume and weight with a significant difference between treatment group and control group as well as indomethacin 1 ms/ks group and indomethacin 2 ms/kg group(P＜0.05).The inhibitory rate of indomethacin 1 ms/kg and 2 ms/kg for tumor was 22.86%,48.00%respectively.The prolifiration index (PI)of ki67 in these 4 groups were (76.73±3.34)%,(73.30±2.95)%,(55.97±2.24)%,(32.87±2.91)%respectively,and significant difference was found in PI between indomethacin 2 mg/kg group and untreated group or NS group(P＜0.05),but there was not significant difference between indomethacin 1 mg/kg and 2 ms/kg group(P＞0.05).Compared with the control group,the indomethacin treatment groups showed the decreased expression of survivin protein and mRNA,and significant difference was found between indomethaein 2 ms/kg group and untreated group or NS group(P＜0.05),however,no significant difference was found between indomethacin 1 mg/kg and 2 mg/kg group(P＞0.05). Conclusion Indomethacin inhibits the growth of CM in nude mice through inhibiting the expression of survivin in the tumor and accelerating cell apoptosis and inhibiting tumor cell proliferation.

Objective To observe the effect of low molecular weight heparin calcium combined with astraga-lus injection in the treatment of diabetic nephropathy.Methods From January 2013 to December 2014,78 patients with stage III diabetic nephropathy in our hospital were enrolled into the study.They were randomly divided into con-trol group(41 cases) and treatment group(37 cases).The control group received general therapy,such as low protein diets,compound alpha keto acid,insulin,irbesartan,simvastatin.The treatment group was treated with low molecular weight heparin calcium and astragalus injection on the basis of general therapy.The changes of urinary albumin and 24 hours urinary protein after treatment in the two groups were observed.Results After treatment,the negative rate of urinary micro albumin in the treatment group ( 75.68%) was significantly higher than that of the control group (29.27%)(χ2 =16.765,P<0.01).24 hour urinary protein of the treatment group[(176.2 ±82.3)mg/24h]was significantly lower than that of the control group[(223.8 ±87.8)mg/24h](t=2.471,P<0.05).Conclusion Low molecular weight heparin calcium combined with astragalus injection can reduce the proteinuria of diabetic nephropa-thy,it is an effective intervention therapy for early diabetic nephropathy.

microRNAs (miRNAs) are a class of small non-coding,single-stranded RNAs,which regulate gene expression by binding messenger RNA (mRNA).Thyroid cancer is the most common endocrine cancer.Papillary thyroid carcinoma (PTC) is a common type of thyroid cancer,and its incidence has dramatically increased worldwide.Recent evidence suggests that miRNAs play an important role in thyroid carcinogenesis,development and prognosis,especially in PTC.

Objective To study the effect of Src tyrosine kinase inhibition on subcutaneously transplanted tumor of human lung adenocarcinoma in mice and its mechanism. Methods For the subcutaneously transplanted tumor model, A549 cells or PC-9 cells were inoculated into SCID mice by subcutaneous injection. Immunohistochemistry was used to show the effect of Src tyrosine kinase inhibition on proliferation index (Ki-67 staining) and microvessel density (CD31 staining) of subcutaneously transplanted tumor of human lung adenocarcinoma in mice. Results Subcutaneously transplanted tumor of PC-9 cells was sensitive to src tyrosine kinase inhibitor. There was significant difference between treatment group and control group (P <0.01). There was significant difference between the two treatment group too (P <0.01). Stopping treatment for 1 week, the inhibition rate of tumor growth were 33.19 % and 84.79 % in 10 mg·kg-1·d-1 and 50 mg·kg-1·d-1 treatment group, respectively. The same treatment was less effective to subcutaneous tumors produced by A549 cells. Treatment with 50 mg·kg-1·d-1 Src tyrosine kinase inhibitor significantly reduced the proliferation index of subcutaneously transplanted tumor produced by PC-9 cells (P<0.01) and tended to reduce the proliferation index of subcutaneously transplanted tumor produced by A549 cells (P >0.05). Treatment with 50 mg·kg-1·d-1 Src tyrosine kinase inhibitor significantly reduced micro vascular density in both PC-9 and A549 induced subcutaneous tumors (P <0.05). Conclusion Inhibition of Src tyrosine kinase could suppress the progression of subcutaneously transplanted tumor, not only by the inhibition of cell proliferation of lung adenocarcinoma cells directly, but also by the inhibition of angiogenesis indirectly.
