  • Expression and Functional Significance of Lung Resistance Protein in Pancreatic Adenocarcinoma Cell

    【Abstract】 Objective To detect the expression of lung resistance protein (LRP) and investigate its significance in pancreatic carcinoma cell lines (SW1990, PCT-2, PCT-3, PCT-4, Aspc-1, Capan-1, Mia-PaCa-2 and Panc-1). Methods Reverse transcription PCR (RT-PCR) and immunocytochemistry (ICC) were carried out to investigate the expression of LRP. Results LRP mRNA was absent in PCT-2 cell line by RT-PCR. Mild to moderate expression level was found in other pancreatic carcinoma cell lines. PCT-4, Aspc-1 and Panc-1 presented the highest LRP mRNA expression level, in contrast, SW1990, PCT-3, Capan-1 and Mia-PaCa-2 showed moderate LRP mRNA expression. The median value was 0.56±0.33. LRP was further validated by ICC. Absent to weak protein expression of LRP was found in PCT-2 and PCT-3. Overexpressed LRP was present in SW1990, Capan-1 and Aspc-1, furthermore, the highest expression of LRP was found in Panc-1, Mia-PaCa-2 and PCT-4 cell lines. Conclusion All these data showed that LRP might play an important role in multidrug resistance of pancreatic carcinoma.

  • Effect of early antiretroviral therapy on acquired immune deficiency syndrome in Butuo County, Liangshan Autonomous Prefecture

    Objective To assess the effect of early antiretroviral therapy on acquired immune deficiency syndrome in Butuo County, Liangshan Autonomous Prefecture. Methods A total of 1 037 patients who underwent antiretroviral therapy between January 1st 2012 and December 31st 2013 in Butuo Coungty were divided into 2 groups. The early treatment group (with CD4+ lymphocyte count >350 /mm3) was group A (n=459) and delayed treatment group (with CD4+ lymphocyte count≤350 /mm3) was group B. After 18-month treatment, the treatment retention rate, clinical effect and the side effects of medication in two groups were observed and analyzed. Results After 18 months, there were 297 (64.7%) and 320 (55.4%) patients who were persisting in treatment in group A and B, respectively; while the mortality was 6.1% (28/459) and 14.4% (83/578), respectively in group A and B. The differences were significant (P<0.001). The rate of virological suppression in group A and B was 64.0% (190/297) and 63.8% (204/320) respectively without any significant difference (P>0.05). Compared with baseline CD4+ T lymphocyte counts, the growth rate of CD4+ T lymphocyte count in group A and B was 5.7% and 37.5%, respectively; the difference was significant (P<0.001) Conclusions Early treatment for acquired immune deficiency syndrome in Butuo County, Liangshan Autonomous Prefecture is effective, however, its growth rate of CD4+ T lymphocyte count is lower than that of delayed treatment. Early treatment doesn’t cause the increasement of the risk of common adverse reactions of medication, and it can reduce the mortality.

  • A SURGICAL STRATEGY AND TREATMENT OUTCOME OF ACQUIRED AURICULAR DEFECT

    Objective To investigate the cl inical outcome of a surgical strategy by soft tissue expansion in treating acquired auricular defect. Methods Between January 2007 and December 2009, 136 patients with acquired auricular defect were treated with a surgical strategy by putting autoallergic costal framework after soft tissue expansion. There were 93 males and 43 females, aged 8-60 years (median, 20 years). Defects were caused by burn in 82 cases, by trauma in 47 cases, and by bite in 7 cases. Defect involved in almost the whole auricle and earlobe in 50 patients, 2/3 superior part of auricle in 35 patients, 1/3 superior part of auricle in 31 patients, 1/3 middle part of auricle in 9 patients, and 1/3 inferior part of auricle and earlobe in 11 patients. Results All the flaps had good blood supply, skin grafts all survived, and all the wounds healed by first intention after operation. All patients were followed up 6-24 months with an average of 14 months. All reconstructive auricle survived with good color, soft texture, and normal sensory function; the appearance had no enlargement and attrition, and the grafted costal cartilage framework had no malacosis, absorption, and deformation. The reconstructed ear had the same position, size, shape, and oto-cranium angle as normal ear. The curative effect was good according to ZHUANG Hongxing’s evaluation standard of auricular reconstruction. Conclusion To reconstruct auricle by soft tissue expansion is an effective method. The position of putting expander and the number of expanders are different in different patients.

  • Present Situation and Progress in Research on HIV/AIDS Laboratory Testing

    Acquired Immunodeficiency Syndrome (AIDS) is a severe infectious disease induced by human immuno deficiency virus (HIV). Laboratory testing plays an important role in the diagnosis of HIV/AIDS. In general, laboratory testing includes detection of virus antibodies and antigens, virus RNA, immune cells (CD4+, CD8+) and anti-HIV drug resistance. During the past twenty years, great progress has been made in laboratory testing. As research on HIV/AIDS has advanced and biotechnology has developed rapidly, different methods of testing have been discovered. In recent years, the application of molecular biotechnology and immunology has led to important advances for epidemiological surveys, clinical diagnosis and treatment of HIV. The existence of a testing method with high sensitivity and specificity is not only helpful for early diagnosis and prediction, monitoring and evaluation of therapeutic efficacy, but can also reduce the risk of false-negative results. HIV laboratory testing is now developing towards a simple, rapid, sensitive, accurate and automatic way of diagnosing this condition.
