Objective To investigate the effect of minocycline on the cognition and expressions of brain-derived neurotrophic factor (BDNF), apoptosis related factor Bcl-2 and Bax in hippocampus of rats with Alzheimer’s disease (AD).
Methods The rat model was established by microinjection of Aβ25-35 into lateral ventricle. Thirty healthy male SD rats were randomly divided into three groups:control group, model group and minocycline treatment group. Normal saline 1 mL/(kg·d) was intraperitoneally injected in control group and model group. The minocycline treatment group was intraperitoneally injected with minocycline 50 mg/(kg · d) for 14 days. Morris water maze was used to detect the behaviors of animals. The expressions of BDNF, Bcl-2 and Bax in hippocampus were measured by Western blotting and enzyme linked immunosorbent assay (ELISA). The apoptosis of neurons was detected by TdT-mediated dUTP nick-end labeling (TUNEL). Results Minocycline greatly improved the behaviors of AD rats, up-regulated the expressions of BDNF and Bcl-2, and down-regulated the expression of Bax in hippocampus, and reduced cell apoptosis. Conclusion Minocycline plays a protective role in neural function by promoting the growth of neurons and inhibiting the neuronal apoptosis.

Septic arthritis of the sternoclavicular joint(SCJ) is a rare condition and accounts for 0.5%-1.0% of septic arthritis.SCJ infections often require surgical intervention.Diabetes mellitus,rheumatoid arthritis,intravenous drug use,intraarticular injection and immunosuppressive disorders are predisposing factors.Staphylococcus aureus and Pseudomonas aeruginosa are the most common bacteriologies.Early diagnosis of SCJ infection requires a high index of suspicion and a confirmatory CT or MRI scan.The characteristic imaging features include intramedullary and soft tissue gas,sequestra,soft tissue swelling and destruction or widening of joint space.Management strategies have ranged from conservative antibiotic therapy to en-bloc resection of the sternoclavicular joint with or without ipsilateral pectoralis major muscle transposition.The shoulder function in most patients were well preserved.

Objective To investigate the effectiveness and safety of simultaneous lung volume reduction surgery in the treatment of lung volume mismatch after single lung transplantation. Methods Twenty-four single lung transplantations were performed on 20 male and 4 female patients, with a mean age of 54. 6 ± 12. 2 years (ranging from 28 to 75 years). Indications for transplantation included end-stage chronic obstructive lung disease (COPD) in 14 cases, COPD combined with upper lobe lung destruction in 1 case, COPD combined with pneumoconiosis in 1 case, end-stage interstitial pulmonary fibrosis in 6 cases, lymphangioleiomyomatosis (LAM) in 1 case, and post-transplantation bronchiolitis obliterans syndrom (BOS) in 1 case. Sixteen cases had right-side and 8 cases had left-side lung transplantation. Lung volume reduction surgeries were performed through open thoracotomy. Graft lung volume reduction was carried out through the same incision as transplantation, and native lung volume reduction through a small anterior lateral incision contralaterally. Patients were divided into lung volume reduction group (group Ⅰ) and control group (group Ⅱ). There were 8 cases in group Ⅰ,including 5 graft lung, 2 native lung, and 1 graft and native lung volume reduction surgeries. In group Ⅱ, there were 16 cases that had no further treatment for lung volume mismatch. Differences in various clinical parameters between the two groups were compared. Results Two out of 14 (14.3%) patients with COPD accepted lung volume reduction, which was significantly lower than that in patients with other diseases (6 out of 10, 60%, P<0. 05). Post-transplantation chest X-ray showed that 50.0% and 25% of patients had an undeflected mediastinum in group Ⅰ and group Ⅱ, respectively (P<0. 05).None of the other clinical parameters had significant difference between the two groups (P>0.05).But a tendency of increase in mechanical ventilation, chest tube drainage time, air leak time, volume of chest drainage, and a tendency of decrease in times and volume of thoracentesis could be observed in group Ⅰ. Lung function test was not performed on 8 cases after transplantation. Sixteen cases (4 in group Ⅰ, 12 in group Ⅱ) had complete lung function data. There was no significant difference in FEV1 improvement after lung transplantation between the two groups (P>0. 05). Conclusion Simultaneous graft or native lung volume reduction surgery is a safe and effective way of ameliorating lung volume mismatch after single lung transplantation, probably by improving ventilation-perfusion ratio.

[ABSTRACT]OBJECTIVETo study the mRNA expression of glucocorticoid receptor(GR) in peripheral blood mononuclear cells in patients with obstructive sleep apnea hypopnea syndrome(OSAHS) and its clinical significance. METHODSReal-time fluorescent quantitative PCR was used to detect GRα mRNA and GRβ mRNA exprssion in PBMC of 30 male patients with moderate to severe OSAHS and 27 healthy male subjects. The relationships between the expression of glucocorticoid receptor mRNA and the apnea hypopnea index, body mass index, neck circumference, waist circumference, the lowest oxygen saturation, the average oxygen saturation, the Epworth sleepiness scale(ESS) score, fasting blood glucose, heart rate and blood pressure were analyzed.RESULTSCompared with the control group, the expression level of GRα mRNA was lower in the OSAHS group(t=2.25,P<0.05) and the expression level of GRβmRNA had no difference between the two groups(t=1.43, P>0.05). We had not found the significant correlation between the expression of GRα mRNA and the clinical parameters above in OSAHS patients.CONCLUSIONThe expression of GRα mRNA in PBMC in moderate to severe OSAHS male patients have a downward trend compared with healthy group, but the mechanism remains unclear.

Objective To observe the effect of shock lymph drainage on multiple organ injury of rats with traumatic hemorrhagic shock (THS) and discuss the relating mechanism. Methods Male Wistar rats were divided into control group, lymph drainage group and lymph return group. The THS model was established in lymph drainage group and lymph return group, when the shock mesenteric lymph was drained in lymph drainage group. The change of the mean arterial pressure ( MAP), the biochemical indices of liver, kidney, myocardium and acid-base, the morphology, ATP contents and ATPase activities of lung, kidney, liver and myocardium were observed. Results The MAP at multiple time points after 80 minutes of infusion, the ATP contents and ATPase activities of multiple organs in lymph drainage group were higher than those in lymph return group. Multiple biochemical indices in lymph drainage group were superior to those in lymph return group, with statistical difference. The inflammation, congestion, degeneration and necrosis were found in organs of lymph return group, but only mild lesions could be seen in lymph drainage group. Conclusions The shock lymph drainage can alleviate multiple organ injury of THS rats, mechanism of which is correlated with improvement of the energy metabolism and maintenance of MAP and acid-base status.
