The questionnaire was adopted so as to investigate the attitudes and recognition of the manufacture eneprises of TCM diagnosis, treatment and rehabilitation equipment (DTRE) to the technical standards of, relevant products. It was found that the construction of the industrial standard and the national standard was lagged behind on TCM DTRE. Under the new situation, the enterprises are highly willing to participate in the development of the industrial, national and international standards and have a certain of understanding on the standard development. Nearly 80 % of enterprises believed that it was necessary to set up the relevant mirror organization for the development of industrial, national and international standard of TCM DITRE. In the future, the standard construction of TCM DTRE must face to the new situation. The constant increasing of the enterprises. and scientific research organizations in the standard construction must promote the development of TCM DTRE.

[Objective]To explore the therapeutic effect of three surgical procedures(anterior approach,posterior approach and posterior-anterior approach) for cervical spondylotic myelopathy(CSM). [Methods]A total of 111 patients with cervical spondylotic myelopathy treated with three surgical procedures from June 2002 to December 2007 were retrospectively analyzed.Group A(anterior approach) comprised 54 patients with a mean age of 57.1 years(ranged,44~75 years).Group B(posterior approach,Laminoplasty) comprised 33 patients with a mean age of 61 years(ranged,41~73 years).Group C(posterior-anterior approach) comprised 24 patients with a mean age of 62 years(ranged,48-78 years).All patients were followed-up,neural function and cervical sagittal alignment were recorded.According to JOA score,preoperative and postoperative follow-up scores were compared,improvement rates were calculated,respectively.[Results]Patients were followed up for 3 months to 5 years with an average of 2 years.JOA scores of the three groups at 3,6,12 months and at the last follow-up after operation were compared with those of preoperation(P0.05).Cervical sagittal alignment(D numerical value) had no statistical difference at the postoperative and the final follow-up between group A and group C(P=0.434,P=0.492,P=0.569).There was significant difference between group B and group A/C(P

Exons encoding the variable regions of the light and heavy chain of the murine McAb HIT3a against CD3 antigen were isolated from HIT3a gene library and inserted into mammalian expression vectors containing the human K and y1 region exons. The chimeric genes were transfected into murine SP2/0 hybridoma cells by Lipofectin. Antibody levels of culture supernatants from transfectomas ranged 21~32 ?g/ml. The chimeric antibodies bound specifically to human T cells and competed effectivelly with the parental anti-CD3 murine McAb for binding to CD3 antigen on human T cells. The ability to promote antibody-dependent cell-mediated cytolysis was significantly enhanced with the chimeric antibodies as compared with anti-CD3 murine McAb. The mitogenic activity of human T cells can be suppressed and enhanced by the anti-CD3 chimeric antibodies. The cytotoxicity to tumor cells and proliferation of human T cells mediated by the anti-CD3 chimeric antibodies were much higher than IL-2 alone. Chimeric HIT3a antibody is a clinically relevant, genetically engineering antibody with potential use in treatment of graft-versus-host disease in tranplantation, autoimmune diseases and some tumors.

Electroacupuncture instruments as Chinese medicine treatment equipment clinically used most extensively play an important role in improving clinical effect of acupuncture treatment. Although the history of electroacupuncture instruments only has more than 60 years, the development of electroacupuncture equipment has experienced a very rich course. Especially in recentyears, the development of electroacupuncture instruments took on a new developing state. It is certain that thedevelopment of electroacupuncture instruments has entered a new era and the future developing speed and quality of electroacupuncture instruments will be significantly raised. By a review of the developing history of electroacupuncture equipmen, this article technically classifies electroacupuncture instruments and deeply analyzes some problems existent in the development of electroacupuncture instruments so as to propose more strict requirements for the future design of electroacupuncture instruments andsatisfy the demand of clinical acupuncture practice.

Follicular dendritic sarcoma is a rare and low-grade malignant soft tissue tumors , often occurs in the lymph nodes, we report a case of tonsil follicular dendritic sarcoma which occured after Non-Hodgkin's lymphoma had be cured. The chief complaint was oropharyngeal foreign body sensation with hemoptysis three years, found in the left neck mass increased with more than 4 months. The left side of the pharyngeal wall thickening and disappearance of parapharyngeal space with the surrounding lymph nodes extremely enlarged and integrated was demonstrated by the contrast-enhanced CT of neck. Finally,the pathological diagnosis was tonsil follicular dendritic sarcoma.

Reference materials are one of the major approaches to achieve measurement accuracy and metrological comparability. Different functions of reference materials should also be distinguished when applied to mass spectrometry as an emerging technology in clinical laboratory. Proper reference materials for validation, calibration and quality control of measurement method can ensure the accuracy and comparability of test results. Based on the problems of reference materials in clinical mass spectrometry, the precautions for the use of reference materials are summarized in the aspects of measurement method validation, calibrator usage and quality control.

Objective To explore the mechanism and way for CT10 regulator of kinase like (CRKL) involving in drug resistance in leukemia cells. Methods The four major proteins included Ras protein, signal transducer and activator of transcripton 5 (STAT5) protein, phosphoinositide 3-kinase (PI3K) protein and paxillin protein in leukemia which involved in signal transduction pathway of CRKL. The expressions of those proteins were detected by Western-blot and immunofluorescent staining and confocal laser scanning microscopy. Results Compared with K562/S cells, the expressions of Ras(41.52±15.47 vs. 23.74±8.67) and PI3K (35.60±12.48 vs. 10.09±0.005) protein were up-regulated in K562/ADM cells (t=3.01,6.13;both P<0.05), while there were no significant changes in the expressions of paxillin (20.10±11.89 vs. 23.11±12.40) and STAT5 protein (25.72±14.46 vs. 17.58±9.21) between K562/S cells and K562/ADM cells(t=0. 18,1.43;both P>0. 0S). Conclusions Ras and PI3K protein may play a role in the multidrug resistance of K562 cell line, while paxillin and STAT5 protein may be not involved in the formation of resistant in K562 cells.

Objective　To explore the relationship of pathological types of lung cancer with sex, age, site, and clinical diagnosis. Methods　The data of 1 310 patients with lung cancer diagnosed with fibrobronchoscopy, was retrospectively analyzed. Results　①The preliminary clinical diagnosed lung cancers which were comfirmed by fibrobronchoscopic biopsy later were mainly small cell lung cancer. ②The percentage of squamous carcinoma was significantly greater in male (78.0%) than in female (49.7%), but the percentage of adenocarcinoma was significantly higher in female (38.1%) than in male (13.1%)(P<0.0001). ③Among the patients with lung cancer, 53.7% was from 40 to 59 years old and 40.2% over 60. The average age of male patients (56.9 years old) was significantly greater than that of female (51.1 years old) (P<0.0001). ④ The average age of patients with squamous carcinoma and adenocarcinoma was greater in male than in female, but that with small cell carcinoma and squamous carcinoma was greater in female than in male. ⑤The percentage of male with lung cancer in the left lung (37.3%) was greater than that of female (26.0%), but the female had lung cancer in the right lung (59.7%) while male had (49.3%). The left and right upper lobe was more (45.4%) in male, but the right upper and lower lobe was more(43.3%) in female. Conclusion　①The fibrobronchoscopic examination is very important in the diagnosis of lung cancer. ②The pathological types and sites of lung cancer is different in different sex and age, which provide the exact bases for medical and surgical treatment for lung cancer.
