BACKGROUND: The quality of life(QOL) of patients with lung cancer is ffected due to depression, reduced lung function, subjective reduced body force, fatigue, and poor stamina, etc., and the survival of the patientswould be affected by complications or advanced stage cachexia.OBJECTIVE: To investigate the relationship between three gene proteins including p53, p27 and bcl-2 and the pathological characters of non-small cell lung cancer (NSCLC).DESIGN: An experimental trial by employing pathological specimens as subjects.SETTING: Department of respiration of a university affiliated hospital and the Central laboratory of a university.PARTICIPANTS: Totally 76 specimens of NSCLC after surgical resection between June 1997 and December 2002, which were all primary lung cancer without any other therapy.METHODS: The expression of three gene proteins in 76 NSCLC specimens was detected by SP immunohistochemical analysis.MAIN OUTCOME MEASURES: Positive expression of p53, p27 and bcl-2.RESULTS: Among 76 specimens, 28 cases(37%, 28/76) with excessive expression of p53, 34 cases(45%, 34/76) with excessive expression of p27, 37 cases(49%, 37/76) with excessive expression of bcl-2, and 7 cases with excessive expression in all three proteins. The positive expression of p53 elevated with the reduced gradation in differentiation; bcl-2 and p27positive expressions reduced with the reduced gradation in differentiation and there was significant difference between high-differentiation group and low-differentiation group( P ＜ 0. 05) . However, there was no significant relationship between the positive expressions of three proteins and the histological classification, lymph node metastasis, and pathological aging of lung cancer( P ＞ 0.05).CONCLUSION: The excessive expression of p53, p27 and bcl-2 genes might be related with the occurrence and development of NSCLC.

Objective To investigate the effect of teaching mode innovation based on the tech-nology of digital orthopedic in orthopedic clinical teaching for eight-year program medical students. Methods 40 eight-year program medical students who took part in orthopedic clinical trainee in the 2015 school year were chosen and divided into two groups:traditional teaching group and digital tech-nology teaching group. The digital technology teaching group adopted a digital model of orthopedic technology, printing aids, use of auxiliary aids and simulate actual cases operative teaching while an-other group used traditional teaching. After the novitiate, questionnaire investigations were used to evaluate the effect of the orthopedic clinical teaching in both groups. At the same time an examination after the course was used to examine the teaching effect of the two groups, and SPSS 19.0 software was used to do chi-square test and t test to the result of the examination of both groups. Results Compared with the traditional teaching group students, the digital technology teaching group students more agreed with the new teaching mode for their interest in learning and hands-on ability bring positive influence (P<0.05), overall satisfaction of teaching method was significantly higher (P=0.03). The operation ex-amination result [(92.1±9.1) vs. (70.5±9.6)] and the comprehensive examination result (84.6±10.1) vs. (72.3±10.6)were more outstanding, the t test showed that the difference was statistically signifi-cant (P<0.05). Conclusion Teaching mode innovation based on the technology of digital orthopedic in eight-year program medical students has showed obvious advantages in orthopedic clinical teaching, which can stimulate students' interest in learning, improve the teaching effect and have broad applica-tion prospects in orthopedic clinical teaching.

By the breeding model of physics mutagenests (60Co,UV light) and re-strong in the body of insects, We obtained a Bt strain Bt99985 with high insecticidal activity. The shake flask and 40t tank fermentation tests showed that, this strain showed special activity against Spodoptera exjgua, Comparing with original Bt strain: 93005, CK strain: HD-1-580 and GC-91, the value of potency increased respectively by 429%, 655% and 114% in shake flask test. Comparing with GC-91, the value of potency increased by 180% in 40t tank fermentation test.

Objective To investigate the clinicopathologic features,diagnosis,differential diagnosis and treatment of sclerosing angiomatoid nodular transformation(SANT). Methods The clinical data,pathologic characteristics,immunophenotype and postoperative follow-up of SANT were analysed. Results There were no specific findings in the clinical manifestations of the 4 cases of SANT.Grossly,the cut surface of the masses was gray-white and vague nodularity was observed.Microscopically,it was characterized by the multinodular angiomatoid appearance in a fibrosclerotic stroma.The nodules were composed of slit-like,sinusoid-like vascular spaces and were interspersed with a population of spindly or ovoid cells.It was revealed by immunohistochemistry that the expression of CD34 in some vessels' endothelial cells was positive,and CD8 was negative.While in another vessels' endothelial cells,CD8 was positive and CD34 was negative.The expression of SMA,Actin,Vimentin,Collage IV and CD68 was positive in all of the 4 cases,while that of CD21,Desmin and NSE was negative.No relapse or metastasis was found during the follow-up.Conclusion SANT is a rarely encountered benign lesion of the spleen,which should be distinguished from the malignant tumor of the spleen.The diagnosis counts on the pathologic and immunohistochemical findings.It could be cured by splenectomy with a favourable prognosis.

Traditional Chinese medicine has a long history, unique system and perfect technology, which has been used to prevent or treat a variety of diseases in the form of compound medicine. Recently, some of the active ingredients from Chinese medicine were found to have self-assembly properties, mainly through non-covalent interactions, including π-π stacking, electrostatic interaction, hydrogen bond and coordination interactions, etc. Carrier-free nanoparticles based on self-assembly of active ingredients from Chinese medicine could not only improve the solubility of insoluble active ingredients, but also the bioavailability. As nanocarriers, the natural active ingredients could exert synergistic therapeutic effects. The strategy of self-assembly without carrier is safer and almost non-toxic compared to the commonly used nanocarriers. In addition, some ingredients from Chinese medicine could coordinate with metal ions to form stable nanoparticles, which could be applied to photothermal therapy. In this paper, we summarized and analyzed the recent achievements of carrier-free nanoparticles based on self-assembly of active ingredients from Chinese medicine, and briefly outlined the future development of this kind of nanomedicine.

Objective To investigate the molecular characteristics of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patients receiving antiretroviral therapy (ART) in Guizhou Province. Methods Using a convenience sampling strategy, 8 583 samples were collected in Guizhou and an investigation was conducted including face-to-face questionnaire interview and HIV testing. Results 1 511 cases failed in HIV suppression (viral load, VL>1 000 copies/ml). 1 410 cases (93.31%) were successfully genotyped with HIV pol gene, among which 51.42% were genotyped as CRF01_AE, 26.67% as CRF07_BC and 16.1% as CRF08_BC. Conclusion The subtype changes caused by HIV gene mutation should precede the changes of main transmission routes of HIV through the analysis in recent years. Timely monitoring the changes of HIV subtypes can be one of the main bases for the prevention and control of AIDS.

In order to select high quality and suitable Bupleuri Radix varieties in Qingchuan, and establish a new comprehensive method to evaluation the quality of Bupleuri Radix, 12 characters of 14 samples were evaluated by DTOPSIS and grey related degree. The results showed that varieties No. 8 and No. 10 had high quality. DTOPSIS and grey related degree gave the uniformity result, and the biggest difference of value of Ci in DTOPSIS method was 46. 33% , but the biggest difference of the weighting correlation number( r (i)) in grey related degree was only 13.10%. The DTOPSIS combined with grey related degree can evaluate the quality of Bupleuri Radix comprehensively and objectively.
