The contents and methods of library reference service have changed due to the changing views of people on the value of data and the way of thinking and the influence of big data thinking in the era of big data, libraries should thus innovate in their reference service with new ideas, new orientations and new methods.

Objective:To detect serum antibody to CJ in GBS patients with LPS purified from CJ strains (CJ LPS) and total CJ constituents (CJ T) as antigens and to deduce whether LPS is surely the epitope of CJ in the induction of CJ antibodies from the difference between the positive rates of both the two assays with CJ LPS and CJ T and from the concordance rates of the positive cases Methods:Sera from 81 GBS patients, 34 patients with other neurological diseases (OND) and 63 normal controls (NC) were tested with CJ LPS and CJ T by indirect ELISA method CJ LPS was purified by phenol water extraction method from 15 CJ strains of various Penner serotypes, including those isolated from GBS patients CJ T was made by collecting the heat stable constituents of CJ Results:The positively infective rate of GBS were 51 9% by CJ LPS and 56 8% by CJ T antigens There is significant difference between GBS and NC in both assays, as well as OND There is no difference between the positively infective rate of GBS patients detected with the two sets of antigens and between concordance rates of the positive cases Conclusion:High incidence of GBS following CJ infection was confirmed once more, and LPS is probably one of the epitopes of CJ in the induction of CJ antibodies

AIM: To observe the efficacy of hemoperfusion (HP) to treat one case suffering from overdose digoxin poisoning. METHODS: HA 330 ml and YT 160 hemoperfusion cartridges were used and blood vessel was femoral vein, single needle and two chamber catheter. Four HP were done. RESULTS: The blood digoxin level were 16 ?g?L -1 before and after the 1st HP, 9.22 ?g?L -1 at the 2nd, 12.4 ?g?L -1 before the 3th, 10.45 ?g?L -1 after the 3th, 3.22 ?g?L -1 before the 4th, and 2.84 ?g?L -1 after the 4th HP. CONCLUSION: This case demonstrats that multiple HP at different period may decrease the blood digoxin level step by step.

Objective To investigate the clinical features, treatments and prognostic factors of rhabdomyosarcoma (RMS) in the female genital tract. Methods A retrospective analysis was performed on 13 cases of RMS in the female genital tract. Clinical characteristics, treatments and prognosis were compared and analyzed statistically. Results The median age was 21.0 years (range, 6 to 54 years). There were 6 cases vaginal RMS and 7 cases cervical RMS, included 11 cases of embryonal RMS (ERMS) and 2 cases of alveolar RMS (ARMS). According to the Federation International of Gynecology and Obstetrics (FIGO)staging system,there were 6 cases of stageⅠ, 3 cases of stageⅡ, 1 case of stageⅢand 3 cases of stage Ⅳ, the median survival time were respectively 112.5, 153.0, 9.0 and 3.5 months. According to the Intergroup Rhabdomyosarcom Study Group (IRSG) staging system, there were 10 cases of stageⅠ and 3 cases of the stage Ⅳ, and their median survival time were respectively 112.5 and 3.5 months. Nine patients received surgery and the median survival time was 108.0 months (range, 9 to 228 months), 6 of them received chemotherapy after surgery and the median survival time was 152.0 months (range, 9 to 228 months), the other 3 cases did not receive any therapy after surgery and the median survival time was 25.0 months (range, 9 to 108 months). Four patients did not receive surgery and the median survival time was 6.3 months (range, 1 to 117 months). There were 2 cases received combined treatment included radiotherapy and the survival time were respectively 4 and 198 months. There were 8 cases who was survival without disease and 5 cases died of cancer. The median survival time in 13 patients was 25.0 months (range, 1 to 228 months) and the 5-year overall survival rate was 58.6%. Conclusions The prognosis of early stage of RMS in the female genital tract is good. While, the prognosis of advanced stage is poor. The standard treatment strategy is combination of surgery and chemotherapy,whether radiotherapy could improve the prognosis still need further study.

ObjectiveTo analyze the clinical value of anti-myelin basic protein (MBP) antibody in multiple sclerosis (MS).MethodsDetect the anti-MBP antibody in serum of 56 patients with MS, 30 patients with other neurological diseases (OND)and 36 normal control(NC).ResultsThe positive rate were 78.6% of MS, 50% of OND. There was significant difference amonge MS, OND and NC.ConclusionAnti-MBP antibody detection maybe provided evidence for the diagnosis and therapy of MS.

ObjectiveWe report the clinical and pathological features of 8 Chinese myopathy patients with antibodies to the signal recognition particle(SRP).MethodsSerum myositis antibody profiles were tested with immunoblotting.Muscle biopsies were performed for histological,enzyme histochemical and immunohistochemical stainings.The first antibody in the immunohistochemical staining was mouse anti-human monoclonal antibodies including CD8,CD20,CD68,MHC- Ⅰ and CD31.ResultsEight cases showed stark positive of anti SRP antibody,3 of them with positive anti Ro-52 antibody.The muscle biopsies showed necrotic and regenerative muscle fibers associated with infiltration of macrophage,but scattered T lymphocytes in 2 patients.Two of them presented with fiber hypertrophy and proliferation of connective tissue.There were some fibers with positive MHC-Ⅰexpression.Capillaries were almost normal.Conclusion The muscle weakness of myopathy with antibodies to SRP presents as a chronic progressive course and could associate with lung involvement.Fiber necrosis and regeneration are the main myopathological features,which can mimic muscular dystrophy in some cases.

Objective: To investigate the mechanisms of curative effect of Tongxinluo capsule(通心络胶囊) on patients with coronary artery disease and angina pectoris.Methods: One hundred and twelve cases in accord with the diagnostic criteria of coronary heart disease of World Health Organization(WHO) were(randomly) divided into two groups: treatment group(n=60) and control group(n=52).The patients in both groups were treated with routine therapy including ?receptor retardant and ester of nitric acid etc.(Additionally),the treatment group was treated with Tongxinluo capsules,2 capsules each time and 2 times(per day) for 2 months consecutively.The clinical manifestations before and after treatment,the changes of(electrocardiogram)(ECG),microcirculation of nail bed and hemorrheology were observed in all the patients in both groups.Results: The total clinical effective rate and the rate of total improvement in ECG changes were 86.67% and 80.00% respectively after treatment in the treatment group,and compared with the control group(78.85% and 69.23%) the differences were significant(both P

Objective To explore the expression of BCSG 1 in the triple negative breast cancer and the non-triple-negative breast cancer and its significance .Methods The clinical data from 170 patients were retrospectively analyzed,which including 160 breast cancer and 10 benign breast disease .We checked the expression of BCSG 1 in the specimens by the immunohistochemistry to analysis the similarities and differences the BCSG 1 between the triple negative breast cancer and the non-triple negative breast cancer .Results The expression rate of the BCSG 1 was 41.0%in the non-triple negative breast cancer , which was lower than 57.5% in the triple negative breast cancer (χ2 =4.2,P=0.04).Conclusion The expression rate of the BCSG1 in the triple-negative breast cancer is higher than that in the non-triple-negative breast cancer.and it was statistically significant (P<0.05),so the expression of BCSG1 in triple negative breast cancer is unique .It prompt that BCSG1 can be a new treatment target in the triple negative breast cancer .
