【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.
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.
Objective To investigate the feasibility and methods of surgical treatment for HIV/AIDS patients with otolaryngology diseases. Methods From January 2016 to February 2017, nineteen patients with HIV/AIDS who underwent otolaryngology surgery were included in this study. The demographic data of patients, including age, gender, course of disease, CD4+ T lymphocyte count before operation and disease type were collected and the clinical treatment methods were summarized. The curative effect was analyzed retrospectively. Results The operations of all the 19 patients were successful without occupational exposure among medical staff. One patient with papillary squamous cell carcinoma did not received further treatment. The other 18 patients recovered well and their life quality was significantly improved. Conclusions If HIV/AIDS patients with otolaryngological diseases are examined preoperatively and have no surgical contraindications, the operation shloud be performed by controlling the surgical indications strictly. The life quality of the patients may be improved and the patients’ life may be prolonged after the surgery.
ObjectiveTo analyze the clinical characteristics of acquired immune deficiency syndrome (AIDS) complicated with intracranial infection and to explore the nursing countermeasures. MethodsWe retrospectively analyzed the clinical features, laboratory examination indexes, and nursing methods of 12 AIDS patients complicated with intracranial infection between January and December 2010. ResultsIn the 12 patients, 8 were male, 4 were female; 11 were married and 1 was unmarried. The first symptom of headache occurred in 8 patients, and feverin 4 patients. Detection of HIV-1P24 antigen in all the 12 patients with HIV was positive for nucleic acid analysis. After treatment and symptomatic care, 3 cases were cured, 3 quit the treatment voluntarily, 2 improved patients were transferred to a higher-level hospital, 3 patients were readmitted to our hospital after improvement of the situation, and 1 patient died. ConclusionThe most common symptom of AIDS was neural disease. The diagnosis should be based on clinical manifestations, and the epidemiological data should be used as reference. At the same time, attention should be paid to the admission assessment and good occupation protection, health education promotion, improvement of patients' quality of life, and reduction of the incidence of complications and mortality rate.
Objective To investigate the level and influencing factors of perceived HIV stigma and discrimination among people living with HIV/AIDS (PLWHA). Methods By using convenience sampling method, 123 patients were recruited from the department of infectious diseases in a tertiary hospital in Chengdu from April to May in 2017. Berger HIV stigma scale was used to measure the level of perceived HIV stigma. Results The mean score of Berger HIV stigma scale was 113.72±17.890, which revealed a middle to upper level. Among the four subscales, the score of disclosure concerns (3.07±0.462) was the highest, while the score of negative self-image (2.70±0.494) was the lowest. Multiple regression analysis showed that gender and self-perceived health status were the influencing factors of perceived HIV stigma. Conclusions The level of perceived HIV stigma among PLWHA is from middle to upper level. Female gender and poor self-perceived health status are associated with a higher level of perceived HIV stigma. Individualized interventions are required in order to reduce the level of HIV stigma.
Objective To review the surgical treatment progress in repair and reconstruction of acquired auricle defects. Methods The related literature concerning the surgical methods and techniques for acquired auricle defects was reviewed and summarized.

The application of tissue engineering and digital technology for acquired auricle defects can achieve a satisfactory effectiveness. Conclusion The surgical programs for acquired auricular defects have been constantly improved in recent years, and the emerging medical technologies also play a promoting role in the process, which providing a great deal of reference for obtaining structurally clear and stereoscopic auricle.
ObjectiveTo systematically evaluate the effects of cognitive behavioural therapy (CBT) on improving depression, medication adherence and quality of life in people living with HIV/AIDS (PLHIV). MethodsWe searched The Cochrane Library (Issue 4, 2013), Ovid-JBI, PubMed, EMbase, PsycARTICLES, CBM and CNKI to collect randomized controlled trials (RCTs) on improving depression, medication adherence and quality of life in PLHIV from the establishment dates to April 30th 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality. Meta-analysis was conducted using RevMan 5.2. ResultsA total of 17 RCTs were included, involving 2 163 patients. The results of meta-analysis showed that CBT significantly improved PLHIV's depression (SMD=-0.26, 95%CI-0.41 to-0.10, P=0.001), and quality of life (SMD=-0.57, 95%CI-1.04 to-0.11, P=0.02) in 6 months. Meanwhile, CBT significantly improved PLHIV's medication adherence (WMD=3.98, 95%CI 1.67 to 6.30, P=0.000 8) in the long term. ConclusionCBT is efficacious in improving PLHIV's depression and quality of life in the short term, and improving medication adherence in the long term, compared to standard care.
【摘要】 目的 研究人类免疫缺陷病毒(HIV)感染者和获得性免疫缺陷综合症(AIDS)患者CD4+T淋巴细胞数变化(ΔCD4+T)和外周血淋巴细胞总数变化(ΔTLC)的相关性。探讨用ΔTLC预测ΔCD4+T在监测HIV/AIDS患者疾病进展以及高效抗逆转录病毒治疗(HAART)疗效的价值。 方法 回顾性分析2005〖CD3/5〗2008年确诊的91例HIV/AIDS患者的临床资料。 结果 ΔTLC与ΔCD4+T呈直线正相关(r=0809,Plt;001),好于TLC与CD4+T的相关性(r=0712,Plt;001)。分别用ΔTLC 170、330、630、910个/μL细胞预测ΔCD4+T 50、100、200、300个/μL细胞时具有较好的预测价值,各项评价指标符合率基本达到90%以上,显著高于相同时间下用TLC预测CD4+T计数的价值。 结论 应用ΔTLC预测ΔCD4+T,可比TLC更加直观、准确的反映HIV感染者疾病进展和评价AIDS患者HAART的疗效。【Abstract 】Objective To assess the utility of total lymphocyte count (TLC) changes (ΔTLC) in place of TLC to predict the development of HIV/AIDS. To investigate the monitoring value of ΔCD4+T on progress of HIV/AIDS and HAART which predicted by ΔTLC. Methods Clinical data of 91 patiens with HIV/AIDS diagnosed from 2005 to 2009 were retrospectively analyzed. Results A linear correlation was found between the value of ΔTLC and the value of CD4+T changes(ΔCD4+T)(r=0809,Plt;001),which was better than the correlation between TLC and CD4+T (r=0712,Plt;001).Using ΔTLC as 170,330,630,910 cells/μL,respectively for forecasting ΔCD4+T as 50,100,200,300 cells/μL,respectively,had a better predictive value with the area under ROC curve near to 09,significantly higher than using TLC for predicting CD4+T counts. Conclusion ΔTLC is more accurate than TLC to reflect the development of HIV/AIDS.
ObjectiveTo analyze the sensitivity and specificity of polymerase chain reaction (PCR) tests in the detection of cytomegalovirus (CMV) in the diagnosis of patients with acquired immune deficiency syndrome (AIDS), using aqueous humor samples. Methods25 AIDS patients (including 21 men and 4 women) were studied. The age of the patients varied from 24 to 59 years, with an average of (39.2±9.3) years. The CD4+ T cell count was from 1 to 523 cells/μl, with a medium of 40 cells/μl. They were infected with human immunodeficiency virus(HIV)for a period from 15 days to 9 years with a median of 10 months. They were divided into three groups according to the fundus and treatment, including untreated cytomegalovirus retinitis (CMVR), treated CMVR and control group. There were 10 patients without anti-CMV treatment and 7 patients treated previously with foscarnet or ganciclovir whose eyes were diagnosed CMVR. Control group has 8 patients who had normal fundus or minor retinopathy excluded from CMVR. Approximately 100 μl of aqueous humor was obtained by anterior-chamber paracentesis and PCR was performed in all cases. ResultsThere were CMV DNA in 9 of 10 eyes with untreated CMVR (90.0% sensitivity). Of 7 specimens from eyes with treated CMVR, 3 were CMV PCR positive (42.9% sensitivity). All 8 samples of the control group were negative for CMV DNA, indicating the clinical specificity of our PCR was greater than 99.9% for CMVR. The anterior chamber paracentesis did not cause any complications in our patients except for a patient with subconjunctival hemorrhage. ConclusionsThe assay had an estimated sensitivity of 90.0% in detecting untreated CMVR and a sensitivity of 42.9% in detecting CMVR that had been treated. The specificity of this assay was greater than 99.9%.
Objective To evaluate the clinical features, diagnosis, and outcome of the treatment of cytomegalovirus (CMV) retinitis, and the relationship between CMV retinitis and acquired immunodeficiency syndrome (AIDS). Methods A total of 95 eyes of 56 patients with cytomegalovirus retinitis and AIDS were studied. The fundus feature, visual acuity and CD4+ T-lymphocyte counts were analyzed and the follow-up periods ranged from 2 weeks to 18 months. Results Before the definitive diagnosis of CMV retinitis, the courses of AIDS were 4 to 26 months in all patients. In the initial examination, the granular form of CMV retinal lesion was noted in 55 eyes (57%) in which retinal lesion of 46 eyes was peripheral. The fulminant form of CMV retinitis of 25 eyes (26%) was found in the posterior pole and consisted of densely opaque retinal lesions with blotchy hemorrhage and vasculitis. The overlap between these two presentations was noted in 15 eyes. Papillitis was observed in 7 eyes of CMV retinitis in this series of patients. The visual acuity ranged from finger counting to 0.5. The patients with extensive CMV retinitis or CMV retinitis in the posterior pole got poorer vision. The CD4+ T-lymphocyte counts of 30 patients was 0-30 (mean, 15±9/μl), and the survival time ranged from 2 weeks to 18 months (mean, 6.4±3.3 months). The vision was improved and CD4+ T-lymphocyte counts was significantly higher in the group treated with ganciclovir, and progression of CMV retinitis occured and the vision decreased in the non-treated group. Conclusion CMV retinitis is the most common intraocular complication in patients with AIDS. Diagnosis of CMV retinitis is based on the characteristic of necrotizing retinitis which was typically associated with retinal hemorrhage and vasculitis. Ganciclovir is effective for the treatment of CMV retinitis. (Chin J Ocul Fundus Dis, 2002, 18: 89-91)
