The effects of N-addition on litter mixture effects depend on decomposition time: A case from mixed-litter decomposition in the Gurbantunggut Desert.

Changes in nitrogen (N) deposition and litter mixtures have been shown to influence ecosystem processes such as litter decomposition. However, the interactive effects of litter mixing and N-deposition on decomposition process in desert regions remain poorly identified. We assessed the simultaneous effects of both N addition and litter mixture on mass loss in a litterbag decomposition experiment using six native plants in single-species samples with diverse quality and 14-species combinations in the Gurbantunggut Desert under two N addition treatments (control and N addition).

[Therapeutic effect of adjuvant treatment of acupuncture in a period of day from 7:00 am to 9:00 am on non-dipper essential hypertension].

Objective: To compare the infuences on circadian rhythm of blood pressure in the patients with non-dipper essential hypertension between the combined treatment of time acupuncture and western medication and the simple western medication.

Methods: A total of 70 patients with non-dipper essential hypertension were randomized into an acupuncture plus western medication group (35 cases, 2 cases dropped out) and a western medication group (35 cases). In the western medication group, levamlodipine maleate tablets were taken orally, 2.

[Research progress on pathogenesis of temporary osteoporosis in hip].

Transient osteoporosis of the hip(TOH) is classified as a type of bone marrow edema syndrome. TOH is lack of previous study and there is still controversy about his pathogenesis. In recent years, with the development of multi-discipline, such as imaging, pathology, molecular biology, the study has found that the pathological mechanism is complex, while its mechanism is still not clear, which need further research.

[Clinical observation of proximal femoral anti-rotation nail for the treatment of femoral intertrochanteric fracture].

Objective: To explore the curative effect and the recessive loss of blooding of PFNA for the treatment of intertrochanteric fractures of femur.

Methods: From January 2012 to January 2015, a total of 49 patients with intertrochanteric fractures of femur were treated with proximal femoral anti-rotation nail including 41 males and 8 females with an average age of 79 years old ranging from 65 to 91 years old. According to the modified Evans type, 1 case was type I, 12 cases were type II, 36 cases were type III.

[Effect of long-term fertilization on winter wheat yield from the dry land under different precipitation patterns].

Based on 30 years long-term fertilization experiment on the semiarid Loess Plateau in China, we studied the effect of different fertilizer treatments on the winter wheat yield, fertilizer contribution rate (FCR) and precipitation use efficiency (PUE) in different precipitation years (drought, normal and wet years). The result showed that the wheat yield, FCR and PUE were significantly higher in nitrogen + phosphorus (NP) and nitrogen + phosphorus +potassium (NPK) treatments than in control (CK) and phosphorus (P) treatments when winter wheat was planted for 30 consecutive years. The wheat yield, FCR and PUE in NPK treatment were highest, with values of 3480 kg·hm, 61.

[Effects of different perlite additions on physical and chemical properties of sewage sludge compost and growth of Tagetes patula].

In order to resolve the problem of poor permeability of sewage sludge compost (SSC) which was used as the substitution of peat, perlite was used to regulate the permeability of the sewage. The pure SSC was used as control. The proportions of perlite in the mixtures with SSC were 20%, 40%, 60%, 80% and 100% (V/V), respectively.
