According to the course character and training objective, we analyzed the necessity of the experiment teaching reform of microbiology examination . The modules of employable Skills (MES) was applied to the experiment teaching of microbiology examination tentatively. On the basis of the needs of microbiology laboratory jobs, the contents of experimental course were integrated and optimized to skills module , comprehensive training module and application module , which include fourteen study units such as basic techniques of identification of bacteria,the separation and identifi-cation of pathogenic bacteria, microbiology examination of clinical specimen etc. Intensive teaching and multiplex teaching methods were applied to each module according to the module's characteristic, teaching objectives and cognitive rules of students. This teaching reform has achieved initial results.

Objective To explore the effects of peripheral stem cell transplantation on extremely severe bone marrow form of acute radiation sickness.Methods One patient was radiated aecidently with the radiation dosage of 9～15 Gy and diagnosed as extremely severe bone marrow form of acute radiation sickness.Pretreatment was performed at 4th day after the accident and 3 days later,HLA- matched allogeneic stem cell transplantation on the patient was performed.Graft versus host disease (GVHD) was prevented with cyclosporin A (CsA) and mycophenolate mofetil (MMF).Results The haematopoiesis was recovered at 9th day after transplantation.At 11th day after transplantation, WBCs were increased to 14.74?10~9/L and returned to the normal levels subsequently,number of platelets risen to 51?10~9/L and hemaglobin was over 80 g/L.TRS-PCR and blood type dynamic detection testified that the donor's cells were stably implanted,the chromosome aberration and micro- nuclei disappeared after transplantation,and the patient's blood type changed into the donor's at 27th day after transplantation.But the radiation injury were still getting worse complicated with multiple infections,At 68th day after transplantation (75 days after the accident),the patient was died of mul- tiple organs failure.Conclusion Extremely severe bone marrow form of ARS can achieve hematopoie- sis recovery by allogeneic stem cell transplantation,but only hematopoiesis recovery can not cure the immunodefficiency and the radiation injury of the whole body.

In order to adapt to the requirements of the modern clinical laboratory to medical laboratory technology personnel operation ability,our hospital has modified professional microbiology experiment course to modular teaching from the traditional teaching mode.In the process of teaching experiment,the experiment course and clinical practice class are arranged,and the experiment course of microbiology is divided into five modules:basic skills,application,comprehensive training,extension,and clinical practice module.Basic skills module focuses on the foundation that students learn to observe the microbial morphology and master the basic operation technology,at the same time,cultivates the students' sterile ideas and biological safety;Application module pays attention to the detection of various types of bacteria,lets the student have as many times of trying as possible,battle-hardened;Comprehensive training module emphasizes students' ability of analyzing and resolving problems;Extension module guides students actively to make diffusing thinking and comprehensive analysis of problems;The final clinical practice module that combines theory and practice,further consolidates the basic operation skills,cultivates students' comprehensive ability,improves students' the independent working ability and professional thinking and habits.Five modules link up with each other closely and have progressive layers of the process.In sum,modular teaching motivates the students' interest in learning,solves the problem of students' insufficient operating ability,improves the teaching effect and provides a reform method for improving the quality of microbiological test experiment.

Objective: To obtain polycystin-1 intracellular region. Methods: cDNA of polycystin-1 intracellular region was generated by PCR and then cloned into pProEX Hta, which was prokaryotic expression vector. After verified by sequencing, the recombinant was transformed into E.coli host to express and purify the fusion protein by affinity chromatography. Results: 660 bp cDNA of polycystin-1 intracellular region and 2.6×104 fusion protein were obtained. Conclusion: The fusion protein containing polycystin-1 intracellular region is obtained and is helpful for preparing anti-polycystin-1 monoclonal antibody.

Objective：To study the clinical and pathologic features of patients with lupus nephritis (LN) whose myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) were positive. Methods：The clinical and pathological features were analyzed in 18 patients with LN whose MPO-ANCA were positive. And the data of patients with different clinical outcomes were compared. Results：（1）The hematological abnormalities, hypertension and serositis in these patients were more common than general ones with LN. （2）Proteinuria and hematuria were common, the morbidities of gross hematuria and renal failure in these patients were higher than general ones with LN.（3）Various autoantibodies were positive in these patients.（4）Segmental necrosis crescentic nephritis accompanied by density of immunocomplex in glomeruli and vasculitis in intestitium were common.（5）The morbidity of ESRF and mortality of these patients were similar to general ones with LN. The morbidity of tubular atrophy in those with poor prognosis was significantly higher than those survived. Conclusion：The patients with LN whose MPO-ANCA are positive have some difference from those with negative MPO-ANCA, but positive MPO-ANCA is not directly related to the prognosis.

BACKGROUND:The bispectral (BIS) index is a processed electroencephalogram (EEG) parameter with extensive validation and demonstrated clinical utility. The study aimed to investigate the correlation between the BIS index and the prognosis of patients with coma in the ICU. METHODS:A total of 208 patients with coma in the ICU were enrolled in this study. According to the BIS value, the patients were divided into four groups:group I, BIS value 0 to 20; group Ⅱ, BIS value 21 to 40; group Ⅲ, BIS value 41 to 60; and group IV, BIS value greater than 60. The difference in BIS values with the differences in prognosis of patients with coma was compared between the four groups, and the prognosis of patients with coma was stratified into consciousness, coma, vegetative state, and brain death. Subsequently, the best cut-off score of BIS values calculated for determining the correlation between BIS value and mental state was proposed. RESULTS:There are no significant differences in the age and APACHE Ⅱ scores between the four groups (P>0.05). An inverse correlation was observed between BIS value and mental state (r=–0.749, P=0.00). According to the ROC curve, as BIS value was greater than 42.5, there were higher sensitivity and specificity in conscious-coma patients. CONCLUSION:BIS value is correlated with the prognosis of patients with coma in ICU, and BIS value can be a useful marker for estimating the prognosis of comatose patients.

Chronic kidney disease has become a global public health issue with high prevalence, low awareness, poor prognosis and high cost of medical care. In 2015, the Shanghai Municipal Health and Family Planning Commission approved the “Systemic Redesign and Demonstration for Early Detection, Evaluation and Management of Chronic Kidney Disease in Shanghai” as the fourth round of Shanghai 3-Year Action Plan for Public Health System Construction, and the initial results have been achieved in three years. In this program, we established a new system of three-level prevention and treatment for chronic kidney disease by combining medicine with prevention, hoping to achieve early detection, effective prevention and standardize treatment of chronic kidney disease in Shanghai, and to reduce the incidence, morbidity and mortality, so as to make a model for the prevention and treatment of chronic kidney disease in China.
