Objective:To explore the anti-fatigue effect of Tibet maca in mice. Methods: The mice were respectively given the powder or the alcohol extract of Tibet maca. The lactic acid concentration in blood, serum lactate dehydrogenase ( LDH) , the time of weight loading swimming and serum urea ammonia level after the exercise in the mice were detected, and the anti-fatigue effect of the powder and the alcohol extract of Tibet maca was compared. Results: After the 30-day feeding, the serum LDH activity of the mice taking the powder or alcohol extract of Tibet maca was obviously higher than that of the mice in the control group(P<0. 05), the time of weight loading swimming was significantly longer than that in the control group (P<0. 05), and the blood lactic acid concentration after the exercise was obviously lower than that in the control group (P<0. 05). Conclusion: Tibet maca can improve the time of weight loading swimming of mice, and reduce the level of serum urea ammonia after exercise and blood lactic acid concentration, sug-gesting the powder and alcohol extract of Tibet maca have obvious anti-fatigue effect.

Osteosarcoma is the most common maligant in skeletal system.Its treatment is always the focus of most clinical research workers.This article is a brief overview of the research progress of the therapy for osteosarcoma.In addition to neoadjuvant chemotherapy,surgical treatment,this article also includes molecular targeted therapy,gene therapy,and immune therapy.These new advances will contribute to the clinical work.

Objective:To observe the therapeutic effect of the method of clearing lung and descending stomach and its mechanism on gastroesophageal reflux cough(GERC).Method:125 cases of GERC were divided randomly into the treatment group(n=65) treated by the therapy of clearing lung and descending stomach(with a self-designed decoction) and the control group(n=60) treated with Omeprazole and Domperidone,and they were all treated for 12 weeks.Results:The total effective rate was 92.3% in the treatment group and 78.3% in the control group,with a significant difference between the two groups(P

Objective To evaluate the scan technique and clinical value of multi-slice spiral CT angiography(MSCTA) of coronary artery.Methods MSCTA was performed in 86 patients,and 25 of them were also investigated with selective coronary angiography(SCA).The imaging quality of MSCTA in different scanning condition were analyzed.The patency of coronary artery and other branches were examined.The distribution and extent of coronary arterial stenoses were assessed.The findings demonstrated on MSCTA were compared with those seen on SCA.Results(1)The imaging quality on MSCTA of coronary artery was significant better in patients with a heart rate below 60 beats per minute,contrast flowing rate 3.0~3.5 ml/s,volume 120~150 ml and delayed time 22~25 s;(2)in 25 cases,of 71 coronary artery and branches without stenoses examined with MSCTA,68 had identical appearance on both MSCTA and SCA.The distribution and extent of 19 coronary arterial stenoses revealed by MSCTA were correlated exactly with SCA in 29 coronary arterial stenoses.The negative and positive predicted value were 95.8% and 65.5% respectively.Sensitivity,specificity and accuracy were 86.4%,87.2% and 87.0% respectively.Conclusion MSCTA as a noninvasive examination is a valuable method in detecting diseases or variations of coronary artery.

In recent years, w ith the w idespread use of advanced neuroimaging techniques and the aging of the population, more and more asymptomatic smal unruptured intracranial aneurysms (sUIAs) are incidentaly detected in clinical practice. Studies have show n that the prevalence of unruptured intracranial aneurysm (UIA) is 2%-3% in adults, and more than 2/3 of them are smal aneurysms of < 7 mm in diameter. Usualy these sUIAs do not have any symptoms and the risk of rupture is low er. They are also know n as incidental or asymptomatic aneurysms, but they are not w ithout the risk of rupture. At present, there is no unified opinion about w hether to conduct conservative treatment or surgical clipping or endovascular interventional therapy. This article review s the latest research progress of sUIAs ( < 7 mm in diameter), hoping to provide more evidence for clinical assessment, decision -making, and individual treatment of this kind of aneurysms.

Urinary tract infection (UTI)is a commonly encountered disease during routine clinical care. In the mean time, it is also a commonly encountered hospital acquired infection. UTI possesses various clinical symptoms, and usually the symptoms are atypical. The detection of leukocyturia and bacteriuria is an essential index for screening and confirmatory diagnosis of UTI. This article summarized the pathogenesis of UTI, diagnostic criteria, clinical significance and application evaluation of detection of the WBC and bacteria in urine.

Colorectal polyps are common digestive system diseases in children. The important role of endoscopy in the di-agnosis and treatment of colorectal polyps in children has been recognized. With the continuous development of endoscopic techniques, the diagnosis and treatment of colorectal polyp has become safer, more convenient and more effective. In this re-view, the progress in endoscopy for diagnosis and treatment of colorectal polyps in children has been summarized.

Objective To evaluate clinical utility of contrast-enhanced ultrasonography (CEUS) in percutaneous liver biopsy of liver occupying lesions.Methods According to intralesional microperfusion situation observed with CEUS,31 of 32 patients with liver occupying lesions underwent liver biopsy under the guidance of conventional ultrasound.Acquirement of adequate quantity of specimen for pathological examination was successfully achieved.Results Of 32 patients with liver occupying lesions,conventional ultrasound indicated intralesional necrosis and liquefaction in 3 patients,while CEUS indicated necrosis and liquefaction in 10 and multiple occupying lesions in 4 patients,of which 1 of the 2 lesions of 1 patient showed a rapid wash-in and washout of a focal contrast agent,the other lesion of the same patient showed synchronized enhancement with liver in all the three phases,and the remaining 3 patients showed rapid wash-in and washout.Of 6 patients conventional ultrasound indicated no blood flow,CEUS showed varying enhancement in 5 patients and no enhancement during all the three phases in 1 patient considered as focal nodular necrosis and did not undergo biopsy.All the 31 patients with liver occupying lesions underwent biopsy in the enhanced area in the arterial phase of CEUS.On the average,each patient was punctured for 2.13 times (66/31) .The successful rate of biopsy was 100% (31/31) .The confirmation rate was 96.80% (30/31) .Conclusion reflecting the situation of microperfusion sensitively,distinguishing necrosis and liquefaction accurately,determining benign or malignant initially and guiding to puncture accurately,CEUS is of grest clinical importance in biopsy of liver occupying lesions.
