Yunnan Gejiu lung adenocarcinoma cell line,i.e GLC,is used as the immunogen in this paper, Three hybridomas F19,N-35,STA-2,secreating McAb to human lung cancers have been established.After a long period cultured,their secreation of McAb are stable.A large number of human tissues have been tested and observd with the techniques of immunal cytochemistry and histochemistry.The clinical potentials of applycation of these three McAbs have also been studied.

Primary angiitis of the central nervous system is relatively rare. In recent years, research of the disease in neuroimaging, differential diagnosis, treatment and other aspects advanced greatly. This paper provided a systematic review of this disease entity in order to promote neurologists, neurosurgeons and radiologists′ experience in the diagnosis and treatment of the disease.

Objective:To investigate the changes of the levels of CD 4+CD25+Foxp3+regulatory T cells in HDCP peripheral blood and its significance.Methods: From 2013 January to 2014 August 46 hypertensive disorder complicating pregnancy ( HDCP ) patients treated in our hospital ,including 22 patients with mild preeclampsia ,24 cases of severe preeclampsia ,and 25 normal pregnant women,used flow cytometry detected each group patient peripheral blood CD 4+CD25+Foxp3+regulatory T cells.Results: Severe preeclampsia group CD4+CD25+T cell ratio was (5.01±1.04)%,lower than mild preeclampsia group (7.38±1.26)% and normal pregnant women group ( 12.59 ±2.48 )%, the difference was statistically significant ( P<0.05 );Mild preeclampsia and severe preeclampsia group CD4+CD25+Foxp3+T cell absolute number respectively were (0.96±0.11) ×107 and (0.63±0.12) ×107,CD4+CD25+Foxp3+Treg/CD4+T were (2.58±0.93)%and (1.84±0.85)%,were lower than that of normal pregnant women group (1.85± 0.17) ×107 and(5.11±0.99)%,the difference was statistically significant (P<0.05);Mild preeclampsia group and severe preeclampsia blood estriol were (6.16±2.17) mg/L and (3.27±1.15) mg/L,significantly lower than that of normal pregnant women group (11.34±2.4) mg/L,the difference was statistically significant (P<0.05).Conclusion: Hypertensive disorder complicating pregnancy diseases patient CD 4+CD25+Foxp3+regulatory T cells was significantly reduced ,but also serum estriol reduced ,which may be related to the pathogenesis of gestational hypertension disease and immune tolerance .

Long-term or even permanent neuronal injury can follow administration of general anesthetics.It has been confirmed that some elderly patients may experience a decline in cognitive function after general anesthesia.However,the effects of general anesthetics on the central nervous system have not been determined yet.Here we summarize the effects of general anesthetics on the central nervous system in pediatric patients and immature animals.

Objective To study the influence analysis of patients with anxiety and depression in elderly patients with hypertension antihypertensive effect of psychological intervention combined with Flupentixol and Melitracen Tablets.Methods 60 elderly patients with hypertension accompanied by anxiety and depression in our hospital from January 2014 to December 2016 were selected as the subjects.They were randomly divided into the control group and the experimental group, with 30 patients in each group.The control group was treated with conventional antihypertensive treatment, the experimental group were given psychological intervention combined with treatment of Flupentixol and Melitracen Tablets.The clinical indexes of the experimental group and the control group were compared and analyzed.Results After the corresponding treatment, the effective rate of antihypertensive treatment in the experimental group was 28 cases, and the effective rate of depressurization was 93.3%.The effective rate of antihypertensive treatment in the control group was 21, and the effective rate of antihypertensive treatment was 70%.After treatment, the HAMD score and HAMA score of the experimental group were significantly lower than those before the treatment, and the score of the experimental group was significantly lower than that of the control group, with statistical difference(P<0.05).Conclusion The treatment of elderly hypertensive patients with anxiety and depression in patients with better antihypertensive effect of psychological intervention combined with Flupentixol and Melitracen Tablets, can improve the depression and anxiety of patients in a large extent, high safety, is further applied in clinical significance.

RNA interference (RNAi), as a new technology of gene therapy, has been used in the studies of many diseases in vitro, however, targeting delivery of small interference RNA (siRNA) is still a bottleneck for clinical therapy of siRNA agents. Aptamer is a group of oligonucleotides with high affinity and targeting, and is becoming another important means of delivery for siRNA. In this review, we summarized siRNA delivery obstacles in vivo and recent attractive developments increatively using cell-internalizing aptamers to deliver siRNAs to target cells.

Objective:To explore the feasibility and application effect of Mini-CEX in pediatric clinical practice.Methods:Residents who received standardized residency training in pediatrics department of Peking University Third Hospital from March 2016 to September 2017 were selected as research objects. The clinical ability of the residents were evaluated by application of the Mini-CEX structured form. Its effectiveness as a training guide and assessment method was also evaluated. SPSS 25.0 was used for t test. Results:The Mini-CEX scale was refined according to the characteristics of pediatrics. In this study, a total of 36 residents participated in the evaluation and 110 cases were completed by introducing Mini-CEX structured form in 7 examinations. Compared with 2016, the Mini-CEX scores of the residents in the 2017 showed different degrees of improvement in information gathering [(7.4±0.9) vs. (7.7±0.7)], clinical examination [(7.5±1.1) vs. (7.6±0.9)], clinical judgment [(7.5±0.9) vs. (7.6±0.9)], organizational effectiveness [(7.4±0.9) vs. (7.7±0.9)], and overall clinical competency [(7.5±0.9) vs. (7.7±0.9)], without significant differences ( P > 0.05). A total of 17 residents completed the assessments more than or equal to 3 times. Compared with 2016, the mean scores of the 17 individuals' Mini-CEX scales in 2017 were significantly improved in terms of information gathering, organizational effectiveness, and overall clinical competency. Conclusion:The results have shown that the Mini-CEX scale is simple and easy to operate, it maybe helpful to improve the clinical ability of pediatric residents, and it can be used as a method to evaluate the clinical ability of pediatric residents.

Objective:To investigate the anti tumor effect of C 215 gene transfected tumor vaccine and monoclonal antibody superantigen fusion protein C 215 Fab SEA.Methods:B16 melonoma cells were transfected with the gene encoding a human colon adenocarcinoma cell surface glycoprotein C 215 to produce a tumor vaccine,melanoma models were established in C57BL/6 mice to observe the antitumor effect of the tumor vaccine and the fusion protein C 215 Fab SEA.Results:Tumor growth in mice treated with the vaccine together with the fusion protein C 215 Fab SEA was significantly inhibited compared with the control group(P

Difficult cases are frequently found at the department of internal medicine of large hospitals.Better quality of ward-rounds by these department heads is key to medical safety,to better operations,and to reducing medical disputes incurred by malpractice.Focusing on standardizing wardround behavior and medical records,the People's Liberation Army General Hospital established and applied the Quality Standards of Ward-rounds on difficulty cases,which scored expected outcomes of better quality of care and better patient satisfaction.

Hepatic carcinoma is one of the most common malignant tumors in China.Autophagy activity and the change of Nrf2-ARE pathway play an important role in the process of liver tumors.Nrf2 which is an important regulator to liver cancer belongs to the CNC family.Research discovered that after the inhibition of autophagy,Nrf2-ARE pathway activation contributes to the progression of hepatocellular carcinoma.This article summarizes the relationship between autophagy and the Nrf2-ARE pathway and its impact on the hepatic carcinoma.
