OBJECTIVE: To investigate the quantity and species distribution of diatoms in Chuanyang River of Pudong new area of Shanghai and provide references for the invesitigation of water body in forensic practice. METHODS: The water samples collected from 15 areas in Chuanyang River of Pudong new area in September 2012 were examined by microscope to identify the species of diatoms. RESULTS: Cyclotella and Pinnularia were found to be the dominant species within the 12 species of diatoms in Chuanyang River, which showed differences in species among the sections of Huangpu River, the center and the East China Sea. CONCLUSION The differences in subsectional distribution of diatom species in Chuanyang River may provide a new foundation for forensic identification in drowning cases especially in the determination of falling location.

Mutations in isocitrate dehydrogenase are among the most common genetic alterations in intrahepatic cholangiocarcinoma (ICC).Mutant IDH proteins in ICC and other malignancies acquire an abnormal enzymatic activity, allowing the conversion of alpha-ketoglutarate (alphaKG) to 2-hydroxyglutarate (2HG), which inhibits the activity of multiple alphaKG-dependent dioxygenases, and results in alterations in cell differentiation and tumorigenesis.This review will focus on recent advances, which may help understand the function of IDH mutation in intrahepatic cholangiocarcinoma.

Objective:To investigate the effect of 3 HLA matching measures on preventing hyperacute rejection(HAR). Methods:Among 1 152 cases,550 cases received anti donor lymphocytotoxic crossmatch(LXM),335 cases received LXM and HLA serological test,267 cases of the latter again received panel reaction antibody(PRA)test, the change of the HAR rate with different HLA matching measures were analyzed. Results:If LXM value ≤10% or HLA matched loci ≥3,the rate of HAR was unrelated to LXM value or HLA matched loci. HAR rate decreased significantly in patients with LXM and HLA serological test, and decreased more markedly in those with additional PRA test compared with those only with LXM test. Conclusion:HLA test and PRA are necessary and effective to avoid HAR.

The treatment status and progress in T cell lymphoma including epigenetic involved mutations that control DNA and histone methylation were reported and intensively discussed in 2014 international T cell lymphoma forum.According to the theory,treatment with HDAC inhibitor belinostat and romidepsin for peripheral T cell lymphoma (PTCL) can achieve 29 ％-38 ％ overall response rate (ORR) and 13.6 months median relief time.NK/T cell lymphoma in southeast asia is a common malignant lymphoma,15 ％-28 ％ of the NHL accounted in China and Japan for,which is significantly higher than that in the European and American countries,mainly related to EB virus widespread infection.L-asparaginase enzymes,such as SMILE and AspMetDex,can make the early cases with more than 70 ％ long-term survival rate,advanced cases with 40 ％ response rate.Some new drugs,such as pralatrexate,combined with romidepsin can be used in PTCL cases to improve the complete remission rate.

Objective To study the positive influence of a standard trauma system on the care of severely injured patients.Methods The severely injured patients (NISS≥16 points)were divided into study group ( in 2006-2008,after the establishment of trauma center in our hospital) and control group (in 2001-2005,before the establishment of trauma center),which was bound by the establishment of the trauma center in our hospital in January 2006.The injury severity,care and outcomes were recorded by using China Trauma Database and changes in efficiency and quality of injury care were compared.Results The study group (66 patients) and control group (260 patients) with NISS of (20.59 ±4.63)points and (20.57 ± 5.38 ) points respectively,were similar in the distribution of severity ( P ＞ 0.05 ).The emergency care time was (0.33 ± 0.03) hour in the study group,which was significantly shortened compared with (0.57 ±0.35 ) hours in the control group (P ＜ 0.01 ).The length of hospital stay was (27.64 ±29.01 ) days in the study group,which was shorter than (30.84 ± 32.87 ) days in the control group (P ＞ 0.05 ),while the length of ICU stay was (2.98 ± 5.77 ) days in the study group,longer than (2.65 ± 7.00) days in the control group (P ＞ 0.05 ).The recovery rate was significantly increased from 76.5％ to 87.9％ (P ＜0.05) and mortality was significantly decreased from 20.8％ to 9.1％ (P ＜0.05).Conclusion The study indicates that the standard first aid model can notably improve the trauma care in our hospital.

Objective To evaluate the predictive value of modified early warning score (MEWS) and SMART-COP score on mechanical ventilation in patients with severe influenza A H1N1. Methods Fifty cases diagnosed with severe influenza A H1N1 were retrospectively analyzed. The MEWS and SMART-COP score were calculated. The area under the receiver operating characteristic (ROC) curve (AUC) was evaluated using ROC curve. MEWS, SMART-COP score and AUC were analyzed by Z test. Results The AUCs of MEWS and SMART-COP score for predicting mechanical ventilation were 0. 923 and 0. 889, respectively, which were not significantly different (Z=0. 548, P =0. 584).Conclusion Both of MEWS and SMART-COP score are predictive factors of mechanical ventilation in the patients with severe influenza A H1N1.

Objective To explore the efficacy of multilevel anterior cervical discectomy and fusion for aged patients with cervical spondylotic myelopathy. Methods 25 aged patients with cervical spondylotic myelopathy were treated by multilevel anterior cervical discectomy and fusion. Japanese Orthopedic Association (JOA) scores were evaluated,clinical results were graded from excellent to poor using Odoms criteria,and the sagittal alignment of fusion segements were measured using Cobb method. Bone fusion and complications was evaluated. Results The final follow up score according to Odoms criteria was excellent in 8 patients ,good in 14 patients,and fair in 3 patients ,with excellent and good rate of 88%. The JOA score at final follow up(7.8) was significantly higher than preoperative(12. 8),with average improvement rate of 54%. At final follow up,bone fusion rate was 100%. Conclusion Multilevel anterior discectomy and fusion for aged patients with cervical spondylotic myelopathy was effective.

Objective To analyze the antimicrobial susceptibility of Mycoplasma isolates for rational antimicrobial therapy. Methods BioM?rieux IST kit was used for identification and susceptibility testing of Mycoplasma strains.Results Mycoplasma was positive in 49.5% of the specimens tested.Of the Mycoplasma detected,Ureaplasma urealyticum(Uu)alone accounted for 74.7%,Mycoplasma huminis(Mh)alone accounted for 18.1%,and Uu+Mh was identified in 7.2% of the patients.The results of antimicrobial susceptibility testing showed that the Mycoplasma isolates were most susceptible to doxycycline (98.1%).Ciprofloxacin was the least active (17.3%).Conclusions Doxyeycline,josamycin,and clarithromycin can be used in the treatment of urinary tract infections caused by Mycoplasma.
