Objective To investigate the bacterial infection status,etiology distribution and drug resistance of neurological rehabilitation hospitalized patients,to guide the clinical rational use of drugs,to provide a scientific basis for the development of effective prevention and control measures.Methods From January 201 1 to December 201 4,the clinical data of 334 hospitalized patients in department of neurological rehabilitation of our hospital were ret-rospectively analyzed.The pathogenic culture results were analyzed.Results There were 334 strains of pathogenic bacteria,83.53% of gram negative bacteria,47 gram positive bacteria(1 4.07%),8 fungi(2.39%).The top three infected gram negative bacterias were Escherichia coli,Klebsiella pneumoniae,Pseudomonas aeruginosa.The main Gram positive bacteria was enterococcus.The detective gram negative bacterias were mainly sensitive to piperacillin penicillin/tazobactam and cefoperazone /sulbactam and imipenem,meropenem,cefepime,amikacin.The resistance rate of Escherichia coli to gentamicin,piperacillin and levofloxacin was more than 50%.The resistance rate of Kleb-siella pneumoniae to gentamicin and piperacillin was more than 50%.Conclusion The infection rate of urinary tract and respiratory tract is higher in patients with neurological rehabilitation ward,and the infection rate is higher,and the main part of gram negative bacilli,should be aimed at high risk patients and key links,strengthen the implementation of infection prevention and control measures,rational use of antimicrobial agents.

Objective To discuss the role of leukocyte activation and inflammatory processes in the disease of chronic venous insufficiency(CVI).Methods The relevant literatures about the role of leukocyte activation and in- flammatory reaction in CVI were reviewed.Results The role of inflammatory reaction in occurrence and develop- ment of venous diseases has been studied a lot in recent years.It was found that the leukocyte activation and inflam- matory reaction are involved in the structural remodeling of venous valves and walls,leading to valvular incompe- tence and formation of varicose veins.Conclusion Leukocyte activation and inflammatory processes take important roles in the occurrence and progression of CVI.

Objective To clarify the MUM1/IRF4 expression in follicular lymphoma (FL) and its clinical and pathological significance. Methods Ninety-six cases FL were immunostained with MUM1,CD10,bcl-2,bcl-6 and Ki-67 antibodies. The results were compared with their clinical and pathological features. Results The overall MUM1 expression rate in FL was 59.2 % (58/96),including 36.2 % (19/51) grade 1 or 2 and 86.4 %(39/45) grade 3 cases (x2 =24.406,P <0.001). 68.9 % cases with diffuse area were MUM1 positive (x2 =8.161,P =0.004). MUM 1 and CD10 expression had inverse correlation,83.3 % CD10 negative cases were MUM1 positive (x2= 12.649,P<0.001). The mitosis rate and Ki-67 label index were statistically higher in MUM1 positive cases than in negative cases (t = -3.852 & -4.610,respectively,P <0.001). Conclusion MUM1 can be used as a biomarker to divide FL into different malignancies. The MUM1 positive FL may be the feature of high grade non germinal center B cell malignant lymphoma.

The deep fermentation technique of Tricholoma matsutake is systemically studied in this paper firstly. The best culture determined by orthogonal test is 3g/L of cornflour, 1g/L of glucose, 1g/L of bean cake flour, 1mL/L of corn steep liquid, 1g/L of KH 2PO 4. The best fermenting condition is: 25℃, rotating speed 160 r/min, pH5.0,inoculating amount 10%, 120mL culture medium per 500mL flask. Under these conditions, the mycelia reach 12.94g/L after fermenting 12d.

Objective To understand the evaluation on graduates' professional quality from the employment institutions,and to provide the references for the higher vocational schools in improving students' training model and strengthening students' professional quality. Methods The questionnaires designed independently were answered by the employment institutions hiring 2003-2005 four majors(namely nursing,laboratory science,dental technology,optometry) graduates from Shanghai Institute of Health Sciences. Results The overall evaluation of employment institutions on the graduates was quite good,but the evaluation on graduates' professional ability was low. Conclusion With strengthening the student' specialized knowledge and skill training,higher vocational schools must pay more attention to the students' professional ability education.

OBJECTIVE: To establish a technical process for the separation and purification of total flavones from Licorice. METHODS: The static absorption capacity of macroreticular adsorptive resins D101、Hz-806、AB-83 for total flavones from licorice were compared. The macroreticular adsorptive resin columns on the Licorice extractives were eluted respectively with different concentrations of ethanol, then the content, the weight of residue and purity coefficient of flavones from Licorice in the eluant were detected. RESULTS: The optimal technological conditions were found in AB-8 as follows: flow rate=3ml/min, sample concentration=1.5 mg/ml, pH=5 and 80% ethanol was used as eluting agent. CONCLUSIONS: AB-8 macroreticular adsorptive resin can effectively separate and purify total flavones from licorice, the purity coefficient thus obtained being over 50%, which meets the requirement of the study of effective components of herbal medicine.

OBJECTIVETo investigate the clinicopathologic features, immunophenotyping, differential diagnoses and prognosis of histiocytic sarcoma (HS).

METHODSThe clinical and pathologic findings of 4 cases of HS were reviewed. The samples were used for paraffin section, HE stain, immunohistochemistry stain by EnVision method, electron microscope observation. Follow-up information was available in all patients.

RESULTSThe age of patients, 2 males and 2 females, ranged from 22 to 65 years old (median, 43.25 years). The sites of involvement included lymph node (2 cases), skin or soft tissue (1 case) and colon (1 case). The tumor cells were widespread infiltration, diffused distribution, no adhesion to each other. Tumor cells were middling and large, round, orbicular-ovate, polygon, epithelium appearance, plentiful cytoplasm and acidophilia, cystose. Nucelus was round, orbicular-ovate, dissymmetry. Nuclear chromatin was vacuole appearance, basophilia nucleolus, caryocinesia and pathological mitotic figure. Three of the cases showed conjugate nuclei, increased pleomorphism with multinucleated tumor giant cell formation. Focal cytoplasmic with foamy appearance was identified in 2 cases. One case demonstrated foci of spindly sarcomatoid appearance. Hemophagocytosis was identified in 2 cases. The tumor cells of 4 cases were often accompanied by various numbers of inflammatory cells. Immunohistochemical study showed that all cases were diffusely positive for α-1-ACT, CD68, CDl63 and lysozyme. Three of 4 cases also expressed CD45, CD45RO. The electron microscope results of 4 cases showed that the tumor cells were plentiful cytoplasm and a few cytolysosome in the cytoplasm, and no birbeck cytorrhyctes, cell-cell junction and digitation. Amongst the 4 patients with follow-up information available, three died of the disease 6-13 months after diagnosis. One patient, whose lesion was localized at the skin and soft tissue, survived at the present time.

CONCLUSIONHS was a scarce malignant tumor with mature histiocyte morphology and immunophenotype character. The diagnosis should be based on tissue morphology, immunohistochemistry and electron microscope observation to exclude other disorders.

OBJECTIVETo explore the clinical symptom and effect of arthroscopic treatment of symptomatic anterior cruciate ligament (ACL) cysts of the knee.

METHODSClinical data from 12 symptomatic ACL cysts patients from January 2005 to December 2010 were retrospectively analyzed,including 8 males and 4 females,with an average age of (33.7±9.5) years old (ranged, 19 to 53 years old). The locations were the left knee in 5 cases and the right knee in 7 cases. The disease duration ranged from 3 to 48 months,with a mean of (15.8±13.2) months. All cysts were arthroscopically resected. Range of motion was measured preoperatively and postoperatively, and Lysholm scoring system was used to evaluate the knee function.

RESULTSAll the incisions healed by first intention, and no complications occurred. Twelve patients were followed up for an average of (32.3±6.6) months(ranged, 24 to 48 months). The symptoms of arthralgia,swelling and interlocking of the affected knees disappeared. There was no recurrence during the follow-up. There were significant differences in the range of motion and Lysholm score between pre-operation and post-operation.

CONCLUSIONArthroscopic surgery, showing its advantages of minimal invasion and rapid recovery,is an effective measure in the treatment of ACL cysts.
