Objective To explore the effects of Seretide(50/250 μg)in the treatment of patients with stable moderate COPD.Methods Sixty-four patients in the stable period of moderate COPD were randomized into 2 groups,the test group and control group.The control group received routine treatment.The test group received the Seretide(50/250 μg)inhalation in addition to the routine treatment.During the 2-year observation,the pulmonary functions before and 12 and 24 months after treatment were recorded.The clinical symptoms,physical signs,the frequency of acute exacerbation of COPD and hospitaliztion duration were also graded.Results The difference of the parameters before and after the treatment was significant in the treatment group(P ＜0.01)but not in control group(P ＞0.05).The scores of symptoms and signs([2.1 ±0.4]vs.[4.4 ± 0.3],t =2.365),the frequency of acute exacerbation of COPD(29％ vs.47％,x2 =3.547)and hospitalization period ([5.0 ± 1.2]d vs.[10.0 ± 1.6]d,t =2.149)in the treatment group were significantly improved compared with control group after 24 months' treatment(all P ＜ 0.01).Conclusion Seretide(50/250 μg)is able to improve the lung function of the patients with stable moderate COPD and reduce the frequency of acute exacerbation,showing certain value in clinical practice.

Shanghanlun contains the theory of stagnation,though which is concealed among the treating system.This theory is great important to clinical practice.When we have a whole understanding to the theory of stagnation,it is easy to analyze the obstruction-removing therapy.Though this principle hasn't clearly definition,it is connected closely with other regular treating methods.Based on it,the dissertation analyzes all kinds of obstruction-removing therapy in Shanghanlun.That will be very helpful for readers to understand this theory and its significance in clinical practice.

Objective To explore the characteristics of prospective memory ( PM ) deficit in acute stroke patients with cognitive impairment.MethodsSixty patients suffering from acute stroke who met the inclusion criteria in screening with the neurobehavioral cognitive status examination (NCSE) were enrolled into the experimental group. Sixty healthy participants who matched the experimental group in gender distribution and average age and education level were assigned as a control group. All the participants completed several neuropsychological evaluations,including the Chinese version of the Cambridge prospective memory test ( C-CAMPROMT), the Chinese version of the Rivermead behavior memory test (C-RBMT), a digit-span test (DS), the Chinese version of Stroop's word-color test (C-SWCT) and a color trail test (CTT).ResultsTime-based PM (TBPM) scores in the control group were significantly higher than in the experimental group. At the intention initiation stage TBPM scores in the control group were also significantly better than in the experimental group. The TBPM performance of the experimental group was significantly worse than that of the controls when PM performance was compared with other cognitive functions controlled for.ConclusionsThe acute stroke patients with cognitive impairment showed greater TBPM performance deficits than the controls. This may have resulted from impairment at the intention initiation stage. TBPM deficits may exist independently. If so, they could serve as an assessment of cognitive impairment after stroke.

The screw holes of anatomic plate are oval, and longitudinal axis of the screw hole is parallel to the axis of the plate. The plate surrounding the screw hole is smooth, parallel to the longitudinal axis of the long bone. Under outside force or inside force, the top of screw can move on the smooth surface surrounding the screw hole; the movement is a reversible one. Domestic plate can fix bone fracture stably, and the outside force and inside force can result in micromovement of the fracture ends, stimulating the fracture ends and bone callus formation. Repetitive force is beneficial to bone callus response, protect fragile new vessels and bone trabecula from damage, and promote fracture healing.

Objective Non-small-cell lung cancer with ipsilateral mediastinal lymph node metastasis (N2) belongs to heterogeneous subgroup. We analyzed the prognosis of patients with resected N2 NSCLC to determine the clinical significance. Methods The present study comprised 146 consecutive patients whom underwent surgical resection of N2 NSCLC between January 1997 and January 2000. Histological type, location, T primary tumor status, operation mode, clinical N2 (cN2) factor, N2 level(single or multiple), number of positive nodes(N2-num), and the cycles of adjuvant chemotherapy were estimated from the date of operation using the Kaplan-Meier and Log Rank analysis. The Cox regression model evaluated the influence of factors on the survival. Results The 3-and 5-year survival rate of these N2 NSCLC patients were 19.86% and 14.56%, respectively. The patients with tumor in the right lower lobe showed a significantly longer survival than left lobes. The histological type, tumor location, cN2 factor, N2 level and N2-number were associated with survival. A multivariate analysis using Cox regression identified 4 factors of prognosis: tumor site, T status, N2 level and clinical N2 status. Conclusion This article has identified N2 NSCLC subgroups and found that patients with mN2, N2L1 and single N2 have better prognosis.

Isoliquiritigenin (ISL) is a flavonoid compound isolated from licorice. It possesses excellent antioxidant and anti-diabetic activities. This study aims to investigate the molecular mechanism underlying the alleviatory effect of ISL on energy metabolism imbalance caused by type 2 diabetes mellitus (T2DM). 8-week-old male C57BL/6J mice were used in in vivo experiments. The high-fat-high-glucose diet combined with intraperitoneal injection of streptozotocin was applied to establish T2DM animal model. All animal experiments were performed in accordance with the Institutional Guidelines of Laboratory Animal Administration issued by the Committee of Ethics at Beijing University of Chinese Medicine. HepG2 cells were used in in vitro experiments. Enzyme-linked immunosorbent assay (ELISA) and real-time quantitative polymerase chain reaction (RT-qPCR) were used to examine the protein and mRNA levels of mitochondrial function-related targets. The levels of reactive oxygen species (ROS) and mitochondrial membrane potential (MMP) in HepG2 cells were measured by the flow cytometry. Additionally, the molecular docking of ISL and key target proteins was analyzed. It was found that ISL significantly inhibited the activity of mitochondrial respiratory chain complex I and increased the protein levels of uncoupling protein 2 (UCP2) in the livers of mice and HepG2 cells. It also obviously decreased the ROS levels and increased the MMP levels in cultured HepG2 cells. In addition, ISL promoted mitochondrial biogenesis by activating proliferator-activated receptor gamma co-activator 1α (PGC-1α) and enhanced mitophagy by upregulating Parkin. It also improved mitochondrial fusion by increasing the mRNA and protein levels of mitofusin 2 (MFN2). In conclusion, ISL alleviates energy metabolism imbalance caused by T2DM through suppression of excessive mitochondrial oxidative phosphorylation and promotion of mitochondrial biogenesis, mitophagy, and fusion.

Isoliquiritigenin (ISL) is an active chalcone compound isolated from licorice. It possesses anti-inflammatory and anti-oxidative activities. In our previous study, we uncovered a great potential of ISL in treatment of type 2 diabetes mellitus (T2DM). Therefore, this study aims to reveal the mechanism underlying the alleviatory effects of ISL on T2DM-induced glycolipid metabolism disorder. High-fat-high-sugar diet (HFD) combined with intraperitoneal injection of streptozotocin (STZ) were used to establish T2DM mice model. All animal experiments were carried out with approval of the Committee of Ethics at Beijing University of Chinese Medicine. HepG2 cells were used in in vitro experiments, and sodium palmitate (SP) was applied to establish insulin resistance (IR) model cells. The effects of ISL on body weight, fasting blood glucose levels, and pathological changes in the livers of mice were examined. Enzyme-linked immune sorbent assay (ELISA) and real-time quantitative PCR (RT-qPCR) were applied to detect the regulatory effects of ISL on key targets involved in glucolipid metabolism. Additionally, molecular docking and analytical dynamics simulation methods were used to analyze the interaction between ISL and key target protein. The results indicate that ISL significantly downregulates the transcriptional levels and inhibits the activities of key enzymes involved in gluconeogenesis, including pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PEPCK), and fructose-1, 6-bisphosphatase (FBP). It also downregulates the transcriptional and protein levels of hepatocyte nuclear factor 4α (HNF4α) and cAMP response element binding protein (CREB), the two transcriptional factors involved in gluconeogenesis. Thus, ISL inhibits hepatic gluconeogenesis in T2DM mice. In addition, ISL reduces total cholesterol (TC) and triglyceride (TG) levels in the livers of T2DM mice. Moreover, ISL downregulates the mRNA levels of lipogenesis genes and upregulates those of genes involved in fatty acid oxidation, lipid uptake, and lipid export. In conclusion, ISL suppresses hepatic gluconeogenesis, promotes lipolysis, and restrains lipogenesis in T2DM mice, thereby improving the abnormal glycolipid metabolism caused by T2DM.

Objective To explore nursing of the patients with acute myelogenous leukemia after upper abdominal cluster transplantation.Methods From March 2009 to August 2012,eight cases of upper abdominal organ cluster transplantation were performed in our center,among whom one suffered from acute myelogenous leukemia after operation.We summarized the clinical data and nursing methods of this case.Results The leukocytes,erythrocytes and platetets decreased 22 days after transplantation and the decreasing continued for more than four months.Four bone marrow biopsies were performed.During the first two biopsies,no definite cause of the blood cells decreasing was found,while the outcome of the third time showed that it was type M3 acute myeloid leukemia and genetic testing at the fourth time showed AML1/E-TO was positive.After diagnosis,the patient was shifted to the Department of Hematology and underwent further treatment.Conclusions Close observation,timely diagnosis and treatment,prevention of infection,bleeding and psychological nursing are the keys to promote patients recovery.

Objective To investigation the clinical characteristics in myasthenia gravis (MG)patients with thymomas.Methods A total of 856 MG patients admitted to the department during 2008.7-2010.12 were reviewed retrospectively.The patients with MG were divided into two groups based on thymic pathology,which were 162 cases with thymoma and 694 cases without thymoma.We compared the different clinical features including the gender,age of onset,MG symptoms and the incidence rate of myasthenia crisis.And the relationship between the WHO types,Maosaoka stages of thymoma and the severe of MG was also studied.Results The percentage of thymoma-associated MG patients was 18.9 percent of hospitalized MG patients at the same period.Of the 162 thymoma-associated patients,94 were male and 68 were female,with a ratio of 1.38∶1 and a mean age of (42.9 ± 12.4)years old.Thymoma was more frequent in middle-old aged patients than in children.Compared with non-thymoma MG,more thymomatous patients showed generalised MG,but not only ocular muscles weakness (90.1％ vs 62.4％,P ＜ 0.001 ).There were significant differences of the incidence rate of myasthenic crisis in the two groups ( 14.8％ vs 2.3％ ).(2)WHO type B2 and Maosaoka Ⅰ,Ⅱ thymoma were the commonest types among all potentially MG-associated thymoma.No differences of Osserman MG classification was found in thymomatous patients with different pathologic changes.Conclusions The thymomatous MG patients had its distinctive clinical features:thymomas occured in about 19.7％ of MG patients with more men than women,more common in generalized,higher incidence of myasthenia crisis,with B2 type thymic pathology and Maosaoka Ⅰ,Ⅱstages.No correlation was found between pathologic and clinical stagcs.
