Objective To evaluate the osteogenic potential of selected exercises and determine which one has the greatest value for the elderly.Methods Twenty healthy old subjects were recruited in the study.Each subject performed the following four exercises in random order:stepping onto a 4-in riser (STEP),sit-to-stand (STS),jumping (JUMP) and marching (MARCH).The subjects performed successively each of the 4 exercises for 1 minute,with an interval of 3 minutes between each.The Vicon action capture system was used to record the peak ground reaction of the subjects during their exercises.The osteogenic index (OI) was calculated by the formula:OI=peak GRF/ (body weight×9.8) × In (number of loading cycles±1).Results JUMP and MARCH had superior OI value (7.52 ±2.06,6.51 ±1.59) than STEP (5.22 ±0.63) among the4 exercises (P＜0.05).STS was found to have the lowest OI (2.23 ± 0.42) in the elderly.There was no significant correlation between the height and OI in JUMP and MARCH (P ＞0.05).Conclusion STEP and MARCH had the higher OI value and could be deemed as the better ways to induce positive effects on bone health in the elderly population.

Objective To investigate the effects of Bu Yang Huan Wu Tang on serum contents of microelements sunch as Zn,Cu,Fe,Se and Mn in spontaneously hypertensive rats-stroke prone(SHR/SP). Methods Twenty male SHR/SP of 8 weeks old were divided into two groups: treatment group(n=10),treatmemt with Bu Yang Huan Wu Tang;control group,taking normal feed.Ten WKY rats were served as blank group. The experiment lasted for three months,and the monitored parameters were serum contents of microelements such as Zn,Cu,Fe,Se and Mn. Results It was revealed that the serum contents of Zn,Mn and Se of the blank group were significantly higher than those of the treatment group(P0.05). Conclusion Bu Yang Huan Wu Tang may have regulatory effects on the serum contents of microelements such as Zn,Cu,Fe,Se and Mn in SHR/SP.

Objective To learn about electrolytes imbalance and water intoxication in children treated with high-dose cyclophosphamide(HD-CTX)as well as the renal function and the relative clinical symptoms,and study the mechanisms of hyponatremia.Methods Patients' clinical manifestations during and after HD-CTX therapy were summarized.Serum electrolytes and creatinine(Cr)were detected before and 6 or 8 hours after therapy with HD-CTX,antidiuretic hormone(ADH) in some patients were measured.Results Of 108 therapeutic cases 24 accompanied with vomits and 22 with a decreased urine output,in which 4 developed eyelid or ankle edema.Seven cases had neural-sarcous symptoms and 5 cases had abdominal pain or diarrhea.Serum sodium decreased significantly after HD-CTX[(139.12?3.30) mmol/L vs(134.06?8.23) mmol/L] in whom rechecked after 6 h,(141.77?3.59) mmol/L vs(133.26?6.41) mmol/L in those rechecked after 8 h(Pa0.05].Serum Cr increased 8 h after therapy[(29.95?13.61) ?mol/L vs(43.33 ? 17.25) ?mol/L P

The effects of several factors on the chlamydospores production of Trichoderma aureoviride T-33 during the fermentation were researched.Based on the results above, the orthogonal test was made to screen out the best prescription.The results showed that, the best single-factor conditions for the chlamydospores production of T.aureoviride T-33 were, liquid culture of oat powder, 30℃, pH4.0, 120r/min, 24 hours oscillate incubating as well as liquid culture volume of 80mL/bottle when the 250mL size triangle bottle was used.The result of orthogonal test showed that, the best prescription for temperature, pH and oscillating speed was 30℃, pH4.0 and 140r/min.3.37?10~ 7 spore/mL chlamydospores were obtained at this combined condition.

Objective To explore the MSCT manifestations of pulmonary focal ground-glass opacity (GGO)nodules with differ-ent pathological types.Methods The thin-layer CT images of 87 patients with GGO nodules were retrospectively reviewed.Of them, 57 cases were confirmed by surgery and pathology,including 8 inflammations,2 benign tumors,1 1 adenomatous hyperplasias (AAH),1 9 carcinomas in situ (AIS),and 1 7 adenocarcinomas.The other 30 cases were followed up without surgery.Results Blur edge was found in 6 of the 8 inflammations (75.0%).However,the organized pneumonias showed large irregular shape with clear edge.Of 30 pre-infiltrating lesions (AAH or AIS),28 (93.3%)were ranged from 0.8 cm to 2.0 cm,26 (86.7%)were round or nearly round,25 (83.8%)showed clear edge,and 25 (83.8%)had blood vessels penetrated signs.Of 17 adenocarcinomas,15 (88.2%) were larger than 2.0 cm,13 (76.5%)showed irregular or lobular shape,8 (47.0%)showed coarse edge,and 10 (58.8%)had pleural indentation signs.Of 36 AISs and adenocarcinomas,9 were solid components (specificity of 95.2%),5 had vacuole signs (specificity of 95.2%),and 13 had penetrated and enlarged blood vessels (specificity of 100%).Conclusion There are characteristic MSCT appearances for different pathological types of GGOs.

Objective To explore the effects of Atorvastatin and Simvastatin on serum levels of lipid,high sensitive C-reactive protein (hs CRP)and ventricular remodeling in patients with acute coronary syndromes(ACS).Methods In this prospective study,96 patients with acute coronary syndrome were admitted in our hospital from December 2014 to September 2016.In the prospectively study,they were randomized into Atorvastatin group(Atorvastatin 20 mg daily,n =48) and Simvastatin group(Simvastatin 40 mg daily,n=48),and serum levels of hs CRP,lipids and changes in myocardial function were detected and compared between two groups before and after treatment.Results The serum levels of hs-CRP and lipids were significantly lower in Atorvastatin group than in Simvastatin group at 8 weeks after treatment(P＜0.05).At the end of the treatment,the levels of left ventricular reject fraction and left ventricular end-diastolic volume index were improved (all P ＜ 0.05) in two groups,but significantly higher in Atorvastatin group [(44.8 ± 6.3) ％ and (62.7 ± 10.4)] than in Simvastatin group [(48.9 ± 6.9) ％ and (67.9 ± 10.5) respectively,all P ＜ 0.05).Conclusions Simvastatin and Atorvastatin can effectively promote the decrease in levels of blood lipids and inflammatory reaction,and help to improve the myocardial function in patients with acute coronary syndrome,but Atorvastatin effects are more significant.
