Objective To illustrate the chest radiography and MSCT findings of measles pneumonia in adults. Methods One hundred and sixty three measles patients underwent chest radiography, MSCT was performed in 3 of them. Measles pneumonia was confirmed in 10 patients (6.13%). Results Eight of 10 patients had abnormal appearances in initial chest radiography. The characteristic chest radiographic findings were ground-glass opacities (n=6) and bronchial wall thickening (n=2). MSCT showed bilateral multiple ground-glass opacities in 1 patient,unilateral patchy ground-glass opacities with lobular distribution in the right upper lung in 2 patients. Conclusions Familiarizing with radiographic and MSCT appearances of measles pneumonia in adults is very important for the differential diagnosis and appropriate management of measles pneumonia. Normal initial chest radiography cannot exclude the involvement of the lungs.

Tendon adhesion easily occurs after the operation.The outcome of tendon repair can be affected by adhesion, in-terfering with their normal gliding function.With increasingly deepened konwledge of the tendon healing process and continuous devel-opment of sciences related to medicine, a variety of effective approaches are provided to prevent tendon adhesion.Antioxidants are new orientations that are provided for prevention of tendon adhesion.Although most researches are only limited to animal experiments, the outcomes are positive.This paper reviews the mechanisms and relevant characteristics of tendon adhesion prevention in order to have a better understanding on the roles of antioxidants for preventing tendon adhesion.

BACKGROUND:There are many methods for evaluating anterior cruciate ligament reconstruction. However, doctors always like to assess the outcome with the objective criteria, such as range of motion and imaging examinations, and patient satisfaction is little considered.OBJECTIVE:To explore the factors that may influence the patient satisfaction after anterior cruciate ligament reconstruction. METHODS:Ninety-eight patients undergoing anterior cruciate ligament reconstruction were enroled, including 58 male and 40 female patients, and the average age was 27.4 years old. All patients were followed up (average 17.5 months) to investigate the patient satisfaction. The factors related to the satisfaction were analyzed, such as age, follow-up time, sex, injured knee, mental health, education, economic situation, postoperative athletic ability, and International Knee Documentation Committee scores. RESULTS AND CONCLUSION:After the follow-up, 72.4% patients said that they were satisfied with the outcome, and 27.6% dissatisfied with the outcome. The mental health, economy situation, postoperative athletic ability, and International Knee Documentation Committee scores were significantly related to the patient satisfaction (P < 0.05). To conclude, improved living and medical standard, intensive communication and psychological counseling, as well as rational postoperative rehabilitation scheme can improve the patient satisfaction after anterior cruciate ligament reconstruction.

Objective:To investigate the mechanism of histone deacetylase (HDAC) inhibitor in down-regulating the expression of HER-2 in breast cancer cells and to provide an innovative therapeutic option to overcome the disadvantages of anti-HER-2 therapy. Meth-ods:HER-2-positive breast cell lines were treated with HDAC inhibitors. The changes in the gene and protein levels of HER-2 were de-tected by qPCR and Western blot. MiRNA microarray was used to identify the HDAC inhibitors, whereas qPCR was used to verify the miRNA expression. Results:In vitro cell experiments confirmed that the HDAC inhibitors TSA and SAHA can down-regulate the expres-sion of HER-2 in breast cancer cell lines. TSA can down-regulate the expression of HER-2 gene in BT474 and decrease the concentra-tions of 100 nmol by 10.7%and 200 nmol by 38.9%(P<0.05). TSA had no effect on the primary cells. The expression of HER-2 gene of BT474 was down-regulated by 93.9%(P<0.05) in the 5μmol/L group but not in the 1μmol/L group. SAHA significantly affected the pri-mary cells at a concentration of 1μmol/L and reduced the cells at 87.1%at a concentration of 5μmol/L. Seven miRNAs were identified from the miRNA microarray. MiR-762 was used as a basis to identify the changes in miRNA. The miRNA sputum identified by miRNA microarray and qPCR may be associated with the down-regulation of HER-2 by HDAC inhibitors. Conclusion: HDAC inhibitors may down-regulate the expression of HER-2 in breast cancer cells by changing some miRNAs.

Objective To evaluate abdominal imaging in AIDS.Methods The imaging examinations(including US,CT and MR)of 6 patients with AIDS associated abdominal foci were analysed retrospectively.All the cases were performed US,and CT scan,of which 4 performed enhanced CT scan and 1 with MR.Results Abdominal tuberculosis were found in 4 patients,including abdominal lymph nodes tuberculosis(3 cases)and pancreatic tuberculosis(1 case).The imaging of lymph nodes tuberculosis typically showed enlarged peripheral rim enhancement with central low-attenuation on contrast-enhanced CT. Pancreatic tuberculosis demonstrated low-attenuation area in pancreatic head and slightly peripheral enhancement.Disseminated Kaposi's sarcoma was seen in 1 case:CT and MRI scan demonstrated tumour infiltrated along hepatic portal vein and bronchovascular bundles.Pelvic tumor was observed in 1 case:CT scan showed large mass with thick and irregular wall and central low attenuation liquefacient necrotic area in the pelvic cavity.Conclusion The imaging findings of AIDS with abdominal foci is extraordinarily helpful to the diagnosis of such disease.Tissue biopsy is needed to confirm the diagnosis.

BACKGROUNDAlthough video-assisted radical operation for lung cancer has been widely accepted for treatment of nonsmall cell lung cancer (NSCLC), the debate over video-assisted thoracic surgery (VATS) segmentectomy still remains. This study analyzed the clinical outcomes using VATS segmentectomy for stage I NSCLC patients to explore the safety and efficacy of VATS segmentectomy for Ia NSCLC.

METHODSRetrospective review was conducted of patients who underwent VATS segmentectomy for clinical stage I NSCLC at Shanghai Chest Hospital between November 2009 and May 2012. VATS segmentectomy was performed on 36 patients. Analyses of the patient group were performed on patient demographics and clinical characteristics, intraoperative parameters, complications, and postoperative survival.

RESULTSThirty-five of thirty-six patients underwent VATS segmentectomy with only one conversion to open thoracic surgery. There was one peri-operative mortality from the segmentectomy group and all other patients are alive with a median follow up of 327 days. The mean volume of chest tube drainage after operation for segmentectomy was 1021.4 ml. Among other parameters, the mean blood loss was 162.5 ml (50.0 - 1600.0 ml), the mean operation time 124.8 minutes (75.0 - 271.0 minutes), chest tube duration 4.1 days (2 - 8 days), and the mean length of hospital stay 6.2 days (4 - 11 days). There was one (2.8%) locoregional recurrence after segmentectomy. Two patients successfully underwent bilateral segmentectomies and are still disease free.

CONCLUSIONFor patients with stage I NSCLC, VATS segmentectomy offers a safe and equally effective option and can be applied to complicated operations such as bilateral segmentectomy.

OBJECTIVETo investigate the induction and culture of adventitious root of Panax notoginseng.

METHODThree ways, induction from the explants of three-year-old P. notoginseng. The explants of regenerated shoots and calluses, were used to induce adventitious roots. The effects of 2, 4-dichlorophenoxyacetic acid, indole-3-butyric acid and naphthylacetic acid on adventitious root induction were investigated respectively. The effects of four modes of separating adventitious roots from the parent tissues on culture in vitro were compared.

RESULTAdventitious roots were successfully induced by three methods, of which the young flower bud callus was the best material for the induction of adventitious root. Indole-3-butyric acid possessed the strongest potency for induction. The liquid culture system was established by continuous culture of adventitious roots together with their parent tissues before separated.

CONCLUSIONThe acquisition and culture in vitro in liquid culture system of adventitious roots of P. notoginseng lay a foundation for the next investigation.
