Chinese yam yield is affected by soil nutrient levels and interactions among N, P, and K fertilizers / 中草药·英文版

OBJECTIVE@#The current fertilization methods for Chinese yam are uneconomic and unfriend to environment. A rational one is very important to achieve desired balance of high yield of Chinese yam, economic and friend to environment. Here, we studied the effects of nitrogen (N), phosphorus (P), and potassium (K) fertilizers on the yield of 'Qinfeng' Chinese yam in shallow-groove directional cultivation.@*METHODS@#The experiments were conducted in Dehua County, Fujian Province, China using a "3414" optimal design. Overall, three fertilizer factors (N, P, and K) were evaluated at the following four levels: 0, no fertilizer; 1, 0.5-fold the typical rate; 2, typical fertilization rate; and 3, 1.5-fold the typical rate. There were 14 different fertilization treatments.@*RESULTS@#Treatment 6 (N2P2K2) produced the longest (75.6 cm) and thickest tubers (4.9 cm) with the highest tuber fresh weight (1311.9 g) and yield (41 015.9 kg/hm2), whereas, treatment 1 produced the shortest (65.6 cm) and thinnest tubers (3.9 cm) with the lowest fresh weight (953.4 g) and yield (28 532.8 kg/hm2) among the 14 fertilizer combinations. The experimental data could be fitted to single-variable quadratic and binary quadratic models but not to a ternary quadratic polynomial model. Appropriate N, P, and K fertilizer application rates increased Chinese yam yield. However, excessive fertilization lowered the yield. Chinese yam yield was significantly and strongly correlated with the amounts of N, P, and K fertilizer applied.@*CONCLUSION@#Based on the single variable quadratic and binary quadratic models, we propose that the quantities of N, P, and K fertilizer used to grow 1 hm2 'Qinfeng' Chinese yam should be 360-388.3, 90-100.95, and 416.3-675 kg, respectively.

Analysis on "Heliang & Heli" Fund Award in military health system / 中华医学科研管理杂志

By analyzing the Military Health System winning "Heliang & Heli" Fund Award between 1994 and 2009,we found that the Military Health System possessed a good scientific basis and high level,but with an unbalanced scientific research development,which suggests the Military Health System should further strengthen its independent innovation ability.

Effects and adverse drug reactions of mtrisone in the treatment of patients with severe acute respiratory syndrome / 中国临床药理学与治疗学

AIM: To study effects and adverse drug reactions of mtrisone in the treatment of patients with severe acute respiratory syndrome. METHODS: The information of the medications in 680 patients with severe acute respiratory syndrome (SARS) in Xiaotangshan Hospital was collected by HIS system and the effects and ADRs of metrisone were staiated. RESULTS: The kinds of drugs of SARS patients who had been cured by metrisone were more than those which were not cured by metrisone. Condition of SARS patients who had been cured by metrisone was more serious than those which were not cured by metrisone. The ADRs rate, blood glucose and leukocyte of SARS patients who had been cured by metrisone are higher than those which were not cured by metrisone while blood K+ is lower. CONCLUSION: The utilization of metrison to SRAS patient should be more cautious to balance the effects and ADRs of metrisone.

Clinical studies on the short-course and efficient treatment of mumps meningitis / 中华实验和临床病毒学杂志

<p><b>OBJECTIVE</b>To investigate the short-course and efficient way to treat mumps meningitis.</p><p><b>METHODS</b>Totally 155 cases of mumps meningitis treated by intrathecal injection with dexamethasone only once were enrolled as experimental group and 55 similar cases treated with the common therapy as control.</p><p><b>RESULTS</b>The time for recoveries of temperature, headache, the pathologic reflexes and the total time of treatment were 32 hours, 15 hours, 12 hours and 3.1 days, respectively, while those of the control group were 58 hours, 24 hours, 32 hours, 6.5 days respectively. There was statistical difference between the two groups (P<0.01 or 0.05).</p><p><b>CONCLUSIONS</b>Intrathecal injection with dexamethasone only once is efficient and safe in the treatment of mumps meningitis.</p>

Damage to non-pulmonary organs like heart and kidney in SARS patients:An analysis of 330 cases / 第二军医大学学报

Objective:To analyze the features and clinical significance of damages to non pulmonary organs like the heart,kidney and peripheral blood in SARS patients.Methods:SPSS 11.0 and SDAS software packages were used to retrospectively analyze the damages to the heart,kidney and peripheral blood in 330 clinically confirmed SARS cases.Results:(1)The heart damage occurred within 1 week after SARS onset in mild cases; the rates of LDH,HBDH,CK and CK MB returning to normal were 74.2%,80.6%,100% and 100%,respectively.In severe cases,the heart damage usually occurred 1 week after SARS onset; the rates of LDH,HBDH,CK and CK MB returning to normal were 32.2%,29.5%,55.2% and 44.4%,respectively.Ten patients whose CK MB didnot return to normal died.(2) The changes of RBC count appeared after an average of 1 week (1 10 d) in 54.2% of the patients.It returned to normal in all the mild SARS cases after an average of 12.5(4 21) d but didnot in 18.4% of the severe cases ( P
