Treatment of depression is divided into drug treatment and non-drug treatment. Drug therapy including tricyclic、 tetracyclic antidepressant category、Serotonin reuptake inhibitors (SSRI)、Serotonin receptor antagonist and re-absorption inhibitors (SARI)、norepinephrine and dopamine reuptake inhibitors (NDRI)、 serotonin and norepinephrine reuptake inhibitors (SNRI)、 norepinephrine and specific serotonergic antidepressants (NaSSA) and synergist to support treatment; Non-drugs treatments include psychotherapy, electric shock therapy、transcranial magnetic stimulation (TMS) and deep brain stimulation (DBS)treatment.In clinical practice for a number of studies provide hope that patients with depression.

Objective To investigate the factors related with final test for continued learning of rehabilitation. Methods The records of 511 continued learning students for physical therapy were analysed with linear regression, with the results of theoretical and operating test as independent variable, while sex, age, titles, profession, education, works, levels of hospital and evaluations as independent variable. Results The results of both theoretical and operating test related with profession, education, works levels and evaluation. Conclusion The models estimate the results of continued learning for rehabilitation has been established.

Objective By analyzing the correlation between Doppler spectrum of extracranial cerebral vessels ECV and intracranial arterial stenosis IAS to identify the value of hemodynamic change of ECV in predicting IAS Methods One hundred and four patients with moderate to severe IAS or intracranial arterial occlusion were enrolled in the case group while 32 patients without obvious cerebrovascular disease in the same period were enrolled in the control group Ultrasound examinations of ECV were performed for all patients the hemodynamic parameters of bilateral common carotid artery CCA internal carotid artery ICA and vertebral artery VA were recorded and compared between case and control group Results Compared with control group the ECV of patients with IAS had lower velocity and higher resistance index RI Of all the parameters end diastolic velocity EDV of ICA and EDV of VA were most accurate in predicting IAS with best cut off value of 21 3 cm/s 9 6 cm/s and accuracy of 76 1 % 81 0% respectively Conclusions The ECV of IAS patients tend to have lower velocity and higher RI Analysis of hemodynamic parameters of ECV might be useful in predicting IAS.

Osteoarthritis (OA) is the most common form of arthritis, and is the major cause of pain and chronic disability worldwide, causing enormous social and economic burden.Once OA was considered as a 'wear-and-tear' condition and obesity is considered to be one of the most powerful predisposing factors of OA in the weight-bearing joints.However, studies have also linked obesity to OA in non-weightbearing areas, suggesting systemic effects exerted by metabolic factors other than simple local biomechanics perhaps play a role in the high prevalence of osteoarthritis in obese population.Recent studies have shown that systemic metabolic abnormalities, including obesity, diabetes, hypertension, lipid metabolism disorders, atherosclerosis and cardiovascular disease, play an important role in OA pathological process.Metabolic diseases promote the incidence and development of OA through a variety of ways, inducing causing low-grade systemic inflammation, increasing release of adipokines, anabolic cytokines and inflammatory mediators, leading to glucose and lipid metabolism disorders of chondrocytes, upregulating of cartilage extracellular matrix degrading enzymes, raising oxidative stress injury, increasing apoptosis of articular chondrocytes and reducing the cartilage and subchondral bone nutrition supply.These metabolic changes ultimately accelerate the damage of cartilage and promote the incidence and development of OA.Further research on OA and metabolic diseases, has the potential to provide new ideas and methods for the prevention and treatment of OA.

Rats were kept in isobaric hypoxic chamber (O_2=10%)for ? , ? and 4 weeks(6h/day, 6days/week). The lung adrenoceptors were measured by radioligand bindingtechnique. Results showed that the ? adrenoceptor increased at 1st week of hypoxia and de-creased significantly at 2nd and 4th weeks of hypoxia. The change of ?_2 adrenoceptor wasconsistant with that of total ? adrenoceptor but the decrease was more significant. By con-trast, the ?_2 adrenoceptor increased significantly all the time. No change of Kd valuewas found in this study. The data indicated that the changes of adrenoceptors induced byhypoxia caused the domination of pulmonary vasoconstriction which may play a role inthe developement of hypoxic pulmonary hypertension.

Rats were kept in hypoxic chamber. Results showed that hypoxia led topulmonary hypertension and right ventricular hypertrophy, hypercapnia exasperated thishypertrophy but was not to hypertension. At the same time, lung ?_1-adrenoceptor all in-creased in hypoxia with or without hypercapnia groaps, ?-adrenoceptor increased after 1weekof hypoxia, and decreased after 1week and 2weeks of hypoxia with hypercapnia. These resultssuggested that the different type of adrenoceptors showed a different change after hypoxia.Results implied that the imbalance of adrenoceptor in lung might led to domination ofvaso-constriction caused by increased ?-adrenocepor, which might play the role in hypoxicpulmonary hypertension. The followed up increase of ?-adrenoceptor after 2weeks of hypoxiawith hypercapnia might be a compensative effect to eliminate exasperation of ventricular,hypertrophy.

Objective To observe the effect of grape seed proanthocyandin extract(GSPE) on aged patients with obstructive sleep apnea-hypopnea syndrome(OSAHS).Methods One hundred and one cases aged patients with OSAHS who were treated in the Affihated Hospital of North China University of Science and Technology from December 2012 to December 2014 were randomly divided into control group,GSPE group A and GSPE group B,36 cases of each group.The apnea hypopnea index (AHI),rapid eye movement (REM) and micro-arousal index(MAI) were observed by polysomnography (PSG);the fatigue,sleepiness of patients were conducted with fatigue severity scale (FSS) and epworth sleepiness scale (ESS);the peripheral blood malondialdehyde(MDA) levels and superoxide dismutase (SOD) level of before and after treatment were observed by enzyme-hnked immunosorbent (ELISA) method.The control group received continuously positive airways pressure (CPAP) treatment,while GSPE group A and GSPE group B received low and high dose of GSPE treatment oral besides CPAP respectively.Results Before the treatment,there were no significant differences in the terms of AHI,REM,MAI,FSS,ESS,MDA and SOD among the three groups(P＞0.05).After treatment,the scores of FSS,ESS,MAI and MDA in GSPE group B were (2.27±0.84)points,(6.20± 1.16)points,(8.42± 3.27) times/h,(69.40 ± 13.70) nmol/L respectively,lower than that of GSPE group A ((3.84 ± 1.20) points,(8.14± 1.26) points,(10.34± 3.48) times/h,(85.38 ± 12.22) nmol/L respectively) and control group((5.02 ± 1.14) points,(9.40 ± 1.14) points,(13.84 ± 4.08) times/h,(97.96 ± 13.24) nmol/L respectively),the differences were significant(P=0.000).The REM in GSPE group B was (18.28±2.54)％,higher than that of GSPE group A ((15.74 ± 4.32) ％) and control group ((12.38 ± 3.77) ％),there were significant differences among the three groups (P =0.000).While there were no significant differences on SOD levels among the three groups(P＞0.05).The rate of effectiveness in control group,GSPE group A and GSPE B were 70.5％,79.4％ and 90.9％ respectively,the rate of effectiveness in GSPE B was significant higher than GSPE group A and control group,and the difference was significant(P＜0.05).Conclusion GSPE can improve the sleep quality and weaken oxidative stress reaction,and has a good clinical effects for aged patients with OSAHS.
