Objective To study the protective effect of PCF against murine thymocytes apoptosis induced by UVB irradiation.Methods The irradiation damage model of thymocytes caused by UVB was established.Cellular ultrastructuralalterations were observed with TEM.The expressions of P53,Bax and Bcl-2 proteins were examined by immunocytochemical technique. The p38 mRNA gene expression was also determined with the technique of in situ hybridization.Results Apoptotic thymocytes were observed after UVB irradiation.The ultrastructural damages of the cells induced by UVB irradiation were reduced by the treatment of PCF.PCF also raised the expression of Bcl-2 gene and decreased the expression of P53,Bax.The mRNA expressions of p38 were decreased in PCF groups.Conclusion PCF showed significant protective effects on UVB-irradiated murine thymocytes in vitro.

Objective To study the preventive effects of nerve growth factor(NGF)on basal forebrain neurons to explore the therapy for Alzheimer disease.Methods Six aged Rhesus monkeys were divided into two groups(group A and group B)randomly.NGF transport from cerebral cortex were blocked in all the monkeys.Group A received homopleural intraventricular implants of polymer-encapsulated cells that were modified to secrete NGF.Group B received identical implants of empty capsules.Results Three to four weeks after operation,the monkeys in the group B displayed extensive reductions in the number of p75NGFr receptor immunoreactive neurons(53%)and choline acetyltransferase immunoreactive neurons (57%to 75%)within the septum.The monkeys in group A appeared to be normal size telative to the atrophic appearance of cholinergic neurons and p75NGFr receptor imrnunoreactive neurons in the monkeys receiving control implants.Conclusion NGF could prevent basal forebrain neuron degeneration in aged monkeys.

Background and purpose:Chemotherapy is the main treatment for advanced non-small cell lung cancer (NSCLC).This treatment can alleviate symptoms,improve the quality of life and elevate the survival rate.Due to serious adverse reaction however,it is very difficult for patients to complete chemotherapy.Elemene emulsion has extensive antitumor effects,mild adverse reaction and the therapeutic effect.The purpose of this study was to explore the efficacy of combining NP (NVB+DDP) chemotherapy with elemene emulsion in a comprehensive treatment of advanced NSCLC.Methods:60 cases of patients with advanced NSCLC were randomly divided into the treatment group and the control group,each group consisted of 30 cases.The treatment group was treated with a combination of NP (NVB+DDP) chemotherapy with elemene emulsion (400 mg d2-d8),while the control group was treated with only the NP chemotherapy.Results:The efficacy in the treatment group was 56.7% and 40% in the control group.There was a significant difference between the two groups in terms of their treatment response (P

ObjectiveTo study the characteristics of the relationship between injury and disease in foren-sic identification cases of cervical trauma with cervical vertebra degeneration, and to explore the prob-lems about how to identify the participation rates of injury and disease using the clinical information, forensic examination and imaging examination.MethodsSeventeen forensic identification cases of cervi-cal trauma with cervical vertebra degeneration were collected. The age distributions, injury formations, injury severities and imaging findings of these cases were analyzed and the relationship between injury and disease was evaluated comprehensively.ResultsMiddle-aged and elderly were common in 17 cases and every case was involved with intervertebral disc herniation. The main reasons of injuries were hy-perextension. The degree of injury severity and vertebra degeneration were graded according to the imag-ing findings. The participation rates of injury and disease were also calculated comprehensively.Conclu-sionThe forensic identification cases of cervical trauma with cervical vertebra degeneration should be evaluated with clinical information, forensic examination and imaging finding.

To analyze one case of multi-organ involvement of immunoglobulin G4-related disease and to review the related literatures.Through investigating the clinical data of one case of multi-organ involvement of immunoglobulin G4 (IgG4)-related disease,many related references were retrospected.IgG4-related disease and multi-organ involvement are used as the key words to search on Pubmed and Wanfang Database.According to the clinical manifestations,including serology,imaging,histopathology,responses to steroid therapy,a 65-year-old female patient was diagnosed as IgG4-related disease.The patient exhibited salivary gland swelling,lacrimal glands,and orbital soft tissues.And multiple organs such as pancreas,liver,bile duct,retroperitoneum,the lymph node,lung,paranasal sinuses,kidney and ureter were affected in the patient.Glucocorticoids are the mainstay of therapy and the recommended dose is 0.5-1.0 mg · kg-1 · d-1.Immunosuppressive agents need to be used in relapsing patients or in the patients with multi-organ involvement and serious complications.IgG4-related disease usually affects many systems and involves multiple organs,which is always misdiagnosed to other diseases.Both the correct diagnosis with multidisciplinary fields and the early treatment with glucocorticoids are very important.

Objective:To investigate the availability for rhIL-18 in the in vitro culture system to stimulate PBMHCs,with inducing cytotoxicities against tumor cells and to analyze the influencing factors for the effects.Methods:The NK cells,T cells and dendritic cells were separated from fresh PBMNCs by using the Stem Sep TM immunomagnetic beads.Cell phenotypes of the purified cell populations were identified with FCM technique.The cell co-culture system was established as follows.The PBMNCs or the cell preparations deleting the definite cell subset with immunoscreening were co-cultivated with mitotic-inactivated tumor cells in the presence of rhIL-18.Cytotoxicities of the various effector cell preparations to a series of tumor cell lines were examined by the isotope releasing assay.Results:In the in vitro cell co-culture system,rhIL-18 rapidly induces activation of the cytolytic responses against various tumor cell lines mediated by PBMNCs.The rapid induction within 24 h of culture was dependent on the dosage of rhIL-18,with the optimal dose of 100 ng/ml of the cytokine.The activated cytotoxicities were abrogated by deleting NK cells prior to the cell co-culture but did not vary when either T cells or DCs were removed.The cytotoxic responses were shown as a pattern of broad-spectrum to the target cells used and were not blocked by anti-MHC moAbs.Conclusion:NK cells were responsible for the rapid induction of cytotoxicities against tumor cells by rhIL-18.

0.999) and the limits of detection were 0.03-0.6 ng/ml. The average recoveries were 85.5%-113.1%, RSDs were 1.8%-4.6%. Conclusion With the accuracy, high sensitivity and reproducibility, the method is suitable for the determination of organochlorine pesticide residues in the honey.

Objective To know the situation of HCH and DDT residues in the health foods in Shandong Province, China. Methods HCH and DDT residues in 102 different kinds of health food samples were determined by capillary gas chromatography in 2006. Results The detection rate of HCH was 100%, the eligible rate was 97%, as for DDT, they were 62.7% and 96.1% respectively. Conclusion The situation of organochlorine pesticide residues in the health foods in Shandong Province is not satisfactory and to ensure the quality of the health foods, a powerful supervision should be taken, the raw materials of the health foods should be natural and no pollution.
