【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.
Abstract： Objective To explore the optimal timing and treatment of acquired Lutembacher’s syndrome. Methods Sixteen acquired Lutembacher’s syndrome patients were studied retrospectively based on records collected between January 2000 and December 2009 in Beijing Anzhen Hospital. There were 9 males and 7 females at age of （39.45±10.23）years. All of them underwent endotracheal intubation, intravenous general anesthesia, and cardiopulmonary bypass. All patients were operated on through a median sternotomy incision into the chest, the right atrium, atrial septal defect to expand with mitral valve replacement and atrial septal defect repair. Postoperative mortality and perioperative complications were observed. During follow-up, periprosthetic leakage was observed using echocardiography, along with the level of residual atrial septal shunt, ventricular size, pulmonary artery pressure changes, and improvement in cardiac function. Results Two of the 16 patients（12.5%）died, one of renal failure, and one of respiratory failure. One patient required extracorporeal membrane oxygenation for 3 days, one required continuous renal replacement therapy for 11 days because of acute renal failure, and one experienced respiratory failure and used a respiratory machine for 23 days. All three of those patients recovered. Fourteen patients were followed up for between six months and five years, and the follow-up rate was 100%. The left ventricular end-diastolic diameter was （42.1±5.7） mm, as measured by echocardiography six months post-operation. There was no detectable periprosthetic leakage or residual shunt. The ejection fraction was （67.4%±6.7%）, and estimation of pulmonary artery pressure was （23.4±5.4） mm Hg. Twelve patients were class Ⅱ（ New York Heart Association） and two patients were class Ⅲ. Conclusion Acquired Lutembacher’s syndrome should be treated promptly if patients’ left ventricular end stage diastolic volume index is good enough to ensure they can tolerate surgery. Extracorporeal membrane oxygenation （ECMO）should be used early in patients who are anticipated to be difficult to withdraw from extracorporeal circulation perioperatively.
ObjectiveTo observe the image characteristics of OCT in patients of acquired immunodeficiency syndrome (AIDS) with cytomegalovirus retinitis (CMVR).MethodsThirty-nine eyes of 26 patients of AIDS with CMVR diagnosed in Department of ophthalmology of Beijing Ditan Hospital Capital Medical University from January 2015 to December 2017 were included in this study. All the patients were males, with the mean age of 33.12±9.87 years. All the patients underwent the OCT examination by Spectralis HRA+OCT. The locations of scanning were macular, optical papilla and posterior pole of retina with retinitis. Typical images were saved and analyzed.ResultsThe OCT pathological changes of CMVR included increase of retinal thickness and reflex of retina, indiscernible retinal layers, irregularity or absent external limiting membrane and/or ellipsoid zone, hyperreflective spots, vitreous cells. Among 39 eyes, there were 6 eyes with strong point-like reflection in the outer layer of retina around the lesion, 31 eyes (79.49%) with strong point-like reflection in the full layer of retina, 25 eyes (64.10%) with lesion involved macular area, 34 eyes (87.17%) with vitreous cells.ConclusionsOCT images of the eyes with AIDS with CMVR were characterized by lesions involving the whole retina. Absent ellipsoid zone or structural changes can be seen in the affected areas and peripheral areas of the lesion.
ObjectiveTo comparatively analyze for the fundus characteristics of acquired immune deficiency syndrome (AIDS) with cytomegalovirus retinitis (CMVR) between first-visit and non-first-visit in ophthalmology.MethodsA retrospective study was performed for 22 patients (41 eyes) diagnosed as CMVR with AIDS by ophthalmology in the Affiliated Municipal Hospital of Xuzhou Medical University from July 2004 to September 2017. The patients were divided into two groups: one with the first-visit in ophthalmology (FVO) and the other with the first-visit in non-ophthalmology (FVNO). All patients underwent visual acuity, intraocular pressure, slit lamp microscope and indirect ophthalmoscope examinations. Thirty-nine eyes of 21 patients with clear refractive media were examined by color fundus photography, of which 5 patients were examined by FFA. Five patients examined by OCT and B-mode ultrasound. The CMVR were characterized as fulminant type or indolent type. All the 22 patients (41 eyes) except 2 patients (4 eyes) accepted highly active antiroviral therapy, and all patients were treated with ganciclovir intravenously. Nine patients (12 eyes) received intravitreal injection of ganciclovir, 7 patients (10 eyes) underwent vitrectomy because of retinal detachment, 6 patients (7 eyes) gave up surgery because of extensive retinal detachment, and the other 12 eyes did not undergo any eye surgery. All patients were followed for 6-58 months (average 23±39 months). The incidences and fundus characteristics of the patients with fulminant or indolent CMVR were compared and analyzed. Between the two groups, the difference of visual acuity and CD4+T cell count at the first vist and the last follow-up were analyzed by a t-test, and the macular involvement and spread of the two groups were compared by a chi-square test.ResultsFulminant CMVR showed dense yellow-white necrotic lesions along the great vessels with or without satellite lesions, while indolent CMVR showed sparse yellow-white granular lesions with a little bleeding. The concomitant signs included frost-like dendritic vascular sheath, retinal artery occlusion and optic disc edema. Fourteen eyes of 7 patients in FVO group were fulminant, including 2 patients (2 eyes) with retinal artery occlusion and 1 patient (two eyes) with optic disc edema. In FVNO group, there were 27 eyes of 15 patients, including 21 eyes of 13 cases identified as fulminant type and 6 eyes of 4 patients as indolent type. In the fulminant type, there were 4 patients (6 eyes) with frost-like dendritic vascular sheath, 10 patients (12 eyes) with retinal artery occlusion and 4 patients (4 eyes) with optic disc edema. There was no significant difference in initial visual acuity (t=－1.534, P=0.133), but there was a significant difference in visual acuity at the last follow-up (t=－3.420, P=0.001). There was no significant difference in CD4+ T cells between the two groups at the first visit (t=－0.902, P=0.378). The proportions of macular involvement and 3-4 quadrant involvement in FVO group were significantly higher than those in FVNO group (χ2=7.552, 7.865; P=0.006, 0.005).ConclusionFor AIDS patients with CMVR, the first-visit in ophthalmology showed more dense necrotic lesions involving macular and a wider range of lesions than the first-visit in non-ophthalmology.
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.
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.
Objective To observe the fundus characteristics of acquired immune deficiency syndrome (AIDS) with human immunodeficiency virus (HIV) retinopathy. Methods Eighty eyes of 52 AIDS patients with HIV retinopathy were enrolled in this study. The patients included 42 males (67 eyes) and 10 females (13 eyes). The patients ages ranged from 16 to 78 years, with a mean age of (43plusmn;12) years. All patients' visual acuity, intraocular pressure, slit-lamp microscopy and mydriatic indirect ophthalmoscopy, fundus color photography and CD4+ T cell count was documented. Experienced ocular fundus doctors carried out fundus examinations. Retinopathy characteristics were recorded. Seventeen patients (24 eyes) were followed for a period between two days to two years, with a median of 125 days. We failed to follow up the remaining 35 patients (56 eyes) due to death or moving away. Results Among 52 patients (80 eyes), 28 patients (56 eyes, 70.0%) had bilateral HIV retinopathy and 24 patients (24 eyes, 30.0%) had unilateral HIV retinopathy. Cotton-wool spots (CWS), mostly located close to temporal peripapillary vessels, were found in 46 patients (72 eyes, 90.0%). Six patients (eight eyes, 10.0%) were found to have flaming or spotting hemorrhage located in posterior pole. Among 72 eyes with CWS, 57 eyes were found to have CWS only and 15 eyes were found to also have retinal hemorrhage, mostly located near CWS. Among 24 eyes of 17 followed-up patients, three eyes of three patients were found with no significant changes during the less than two week follow-up. In 18 eyes of 11 patients, CWS or hemorrhage disappeared after one to three months without treatment and in five eyes new CWS or hemorrhage were found in other parts of the posterior pole. Three eyes of three patients initially considered as lint plaque-like lesions were eventually detected with CMVR as lesions during one to five months follow-up. Conclusion CWS are the most common ocular lesions in HIV retinopathy.
Objective To observe ocular manifestations of acquired immunodeficiency syndrome（AIDS）.Methods Fourtytwo AIDS patients（66 eyes）with ocular complaints received examinations of visual acuity, slit-lamp microscope, ophthalmoscope and fundus fluorescence angiography (FFA). The results were retrospectively analyzed. Results There are five types of ocular findings, including cytomegalovirus (CMV) retinitis (37 eyes, 56.0%), retinal microvasculopathy of human immunodeficiency virus (21 eyes, 32.0%), optic nerve diseases (three eyes, 4.5%), retinal neuroepithelial layer detachment (two eyes, 3.0%) and uveitis (three eyes, 4.5%).Conclusions The common ocular manifestations showed progressive necrotic retinitis, retinal hemorrhage and retinal vasculitis and attenuated，cotton-wool spots in AIDS patients.
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.
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.
