The application of reduced dietary crude protein levels supplemented with additional amino acids in laying ducks.

This study was aimed at studying use of reduced dietary crude protein (CP) level supplemented with additional amino acids in laying ducks. A total of 720 Jingjiang ducks (50 wk) were randomly assigned to 5 treatments and fed 5 basal diets with CP levels at 17.5, 16.5, 15.5, 14.5, or 13.5%, with additional amino acids added to each diet for 12 wk. Each treatment had 6 replicates of 24 ducks each. Dietary CP levels affected (P < 0.05) egg production and mass of laying ducks, and there was a linear and quadratic decrease with decreasing CP levels (P < 0.05). Dietary CP levels did not affect egg weight and feed conversion ratio (FCR), but egg weight decreased linearly (P < 0.05); FCR increased linearly and quadratically (P < 0.05) with decreasing CP levels. There were no significant differences in egg quality among the different CP levels (P > 0.05). Ovarian weight, total and mean weight of preovulatory follicles, and total weight of small yellow follicles (SYF) were decreased by dietary CP levels (linear, P < 0.01 and quadratic, P < 0.05). The oviductal weight decreased linearly (P < 0.05), and the number of SYF decreased linearly and quadratically with decreasing CP levels (P < 0.05). The serum estradiol content decreased linearly with dietary CP levels (P < 0.05). The serum contents of luteinizing hormone, prolactin, and progesterone decreased (P < 0.05), linearly and quadratically (both P < 0.01) with decreasing CP levels. The serum contents of creatinine (CRE), triglycerides (TG), total cholesterol (TC), and alanine aminotransferase (ALT) activity were affected (P < 0.05) by different dietary CP levels. The total protein content increased linearly (P < 0.05), TC content increased quadratically (P < 0.05), and contents of albumin, CRE, TG, and phosphorus, and activities of aspartate aminotransferase and ALT increased linearly and quadratically (both P < 0.05) with decreasing CP levels. Overall, reduced dietary CP levels with addition of amino acids affected the laying performance, the development of reproductive organs and ovarian follicles, serum hormones, and biochemical indices of laying ducks. Dietary CP levels can be reduced to 14.5% with additional amino acid supplementation for 12 wk in laying ducks without negative effect on laying performance and egg quality.

The mechanism of exogenous adiponectin in the prevention of no-reflow phenomenon in type 2 diabetic patients with acute myocardial infarction during PCI treatment.

OBJECTIVE: To investigate the mechanism of exogenous adiponectin in the prevention of no-reflow phenomenon in type 2 diabetic (T2DM) patients with acute myocardial infarction (AMI) during percutaneous coronary intervention (PCI) treatment. PATIENTS AND METHODS: 66 patients were randomly divided into control group and observation group, 33 cases in each group. According to the percutaneous coronary intervention (PCI) emergency treatment principle, patients from the control group were treated with an intracoronary injection of adenosine combined with a micro-pump intravenous infusion of tirofiban. Patients from the observation group were injected with exogenous adiponectin in addition to the adenosine and tirofiban treatments. RESULTS: There were no significant differences in gender, age, location of the target lesion, degree of stenosis, stent implantation number, length and the inner diameter between control and observation group (p > 0.05). Lower frequent of slow blood flow and no-reflow and shorter interventional procedures were observed in observation group compared with those of control group (p < 0.05). Moreover, the increase of plasma creatine kinase (CK-MB) in patients of observation group was lower than that of the patients in control group (p < 0.05). In addition, the levels of troponin-I (cTnI), IL-6, TNF- α, endothelin-1 (ET-1), vascular endothelial adhesion molecular I (VCAM-1) and bax/Bcl-2 were significantly lower in observation group than those in control (p < 0.05). Furthermore, the occurrence of major adverse cardiac events (MACE) during a 12-month follow-up was significantly lower in the observation group than that of control (p < 0.05). CONCLUSIONS: Exogenous adiponectin further reduced the no-reflow phenomenon during PCI treatment of the patients with T2DM combined with AMI. The function of exogenous adiponectin is associated with the reduced myocardial and endothelial cell injury and the inhibited inflammation and apoptosis. The application of exogenous adiponectin can significantly improve the clinical outcomes.

Effectiveness of acupuncture in the management of cervical spondylosis: a meta-analysis.

Cervical spondylosis is the most common type of spinal pathology which is more common in middle-aged or senile populations with a high potential to affect physical and mental health. This study evaluates the effectiveness of acupuncture in the management of cervical spondylosis. After a detailed literature search in electronic databases, the required data were acquired from selected research articles and meta-analyses were performed to obtain the percent cure, failure and total effectiveness rates under random effects model. Meta-regression was performed to identify the factors affecting the efficacy. Twenty-seven studies were selected for data acquisition (2,853 patients; average age 46.2±9.5; 51.7±12.5% males). Acupuncture alone had 33.41% (25.50, 41.24) cure rate but in combination with other therapies it rose to 53.36% (41.9, 64.8). Similarly, total effectiveness rate was 87.01% (83.40, 90.62) with acupuncture alone and 93.62% (89.85, 97.38) with acupuncture in combination with other therapies. Age was inversely associated with the percent cure rate and the number of combination therapies with acupuncture was positively associated with the cure rate. In conclusion, acupuncture therapy alone can provide cure and total effectiveness rates of 33% and 87%, respectively, but acupuncture with additional therapies can improve the cure and total effectiveness rates to 53% and 94%, respectively. Age inversely affects efficacy and the number of additional therapies improves the efficacy.

Acupuncture in endocrine disorders: a critical appraisal.

Acupuncture is an integral part of ancient Chinese medical practice. The technique has been used extensively in pain relief and is being tried for many other chronic conditions. Industrial development and affluence lead to the increase in the prevalence of many endocrine disorders such as diabetes, obesity, and polycystic ovarian disease. The rising prevalence of the endocrine morbidity is observed in both the developing and developed nations. The management of these disorders involves major lifestyle modification coupled with a long-term drug intake. In such situations, patients often look at alternative therapeutic options existing in complementary and alternative medicine. The globalization of the world medical practice has led to the spread of acupuncture beyond China to other parts of the world. Acupuncture has been tried extensively in the management of various endocrine disorders with inconsistent results. In this review, we highlight the principles of acupuncture and its role in the management of various endocrine disorders.

IV tissue plasminogen activator use in acute stroke: experience from a statewide registry.

OBJECTIVE: To assess the use of IV recombinant tissue plasminogen activator (rt-PA) in a statewide hospital-based stroke registry and to identify factors associated with its use among eligible patients. METHODS: A modified stratified sampling scheme was used to obtain a representative sample of 16 hospitals. Prospective case ascertainment and data collection were used to identify all acute stroke admissions over a 6-month period. Subjects eligible for IV rt-PA were defined as those who arrived within 3 hours of onset, who had no evidence of hemorrhage on initial brain image, and who had no physician-documented reasons for non-treatment with IV rt-PA. Multivariate logistic regression was used to identify factors associated with IV rt-PA use. RESULTS: Of 2,566 stroke admissions, 330 (12.9%) met the eligibility criteria for rt-PA treatment, and of these 43 (13%) received IV rt-PA treatment. Among 2,236 admissions excluded from consideration, 21% had evidence of hemorrhage on initial imaging, 35% had unknown stroke onset times, 38% had an onset to arrival time >3 hours, and 6% had physician documented contraindications. Among eligible patients, being male, use of emergency medical services, and rapid presentation were associated with increased IV rt-PA use. CONCLUSIONS: Treatment with IV rt-PA was underutilized in this hospital-based stroke registry. The primary reason for nontreatment was delayed presentation. Reducing prehospital and in-hospital response times would help increase IV rt-PA use, as would greater emergency medical services use. Improving the documentation of onset times would help clarify the underlying causes of delayed presentation.

Development of a polymer-enzyme immunoassay method and its application.

Both poly(N-isopropylacrylamide) and poly(N-isopropylacrylamide)-antibody (PINP-Ab)-labelled enzyme adhered quickly and tightly to cellulose acetate/nitrate membrane either below (less efficiently) or above (more efficiently) the lower critical solution temperature, and the retention of PINP-Ab on the membrane increased over 30-fold when compared with the unconjugated Ab. These characteristics were used to develop a novel polymer-enzyme-linked immunoassay method: homogeneous antigen-antibody immune-complexation reaction and a heterogeneous separation process. By using a simple horseradish-peroxidase-labelled antibody as a probe, we applied this method to the detection of human serum hepatitis B surface antigen (HBsAg). This immunoassay system can detect as little as 1 ng/ml of HBsAg. The advantages of this method are: (a) fast homogeneous immune complexation; (b) a rapid heterogeneous separation process; (c) high sensitivity; and (d) low non-specific background.

Rapid isolation of large amount of plasma VLDL and LDL by a two step ultracentrifugation.

A rapid method to obtain large amount of VLDL and LDL by ultracentrifugation is described. The mixture of VLDL and LDL was isolated and concentrated from plasma by an ultracentrifugation at 265 000 g for 2 h. VLDL and LDL were separated and purified by a further ultracentrifugation at 265 000 g for 3 h. This method combines the advantages of both sequential flotation ultracentrifugation and density gradient ultracentrifugation. It can process a large volume of plasma in a short time. The purity of isolated VLDL and LDL was confirmed by the lipoprotein electrophoresis on agarose gel and PAGE and by the apolipoprotein electrophoresis on SDS-PAGE. This rapid economical method is of great value in practical application.

Use of fluorescent substrate 4-MUP in the detection of biotin-labeled DNA probes.

To improve the sensitivity of detecting biotin-labeled DNA Probes, a new fluorescent substrate of alkaline phosphatase, 4-methylum belliferylphosphate (4-mup) was studied instead of conventional BCIP-NBT. The result of dot-blot hybridization demonstrates that this new substrate can be used for the colorimetric detection of biotin-labeled probes after hybridization to immobilized nucleic acids. The sensitivity is about one order of magnitude higher than that of BCIP-NBT system, and the time required for color development is very short, only about five min. It is suggested that the Bio-SA-Bio-AP-4-MUP colorimetric detection system can be widely used in gene diagnosis.

Effect of acute trauma on the levels of intracellular cAMP, cGMP and DNA: studies on endocrinology and metabolism.

In this experiment, we used morgrel dogs to study the effect of trauma on the neuro-endocrine and metabolic organs and the effects of hormones on metabolism by determining the levels of intracellular cAMP, cGMP and DNA. From the changes in intracellular nucleotides, we learned that many neuro-endocrine organs and the main metabolic organs are characteristic of predominance in alpha-adrenoreceptor after trauma, thereby leading to high blood sugar.

Relationship of VLDL receptor and LPL in metabolism of VLDL by macrophage.

Macrophages were incubated with 125I-VLDL for 5 h in presence or absence of lipoprotein lipase (LPL) inhibitor, benzene boronic acid (BBA). Both the uptake and degradation of 125I-VLDL by macrophages were saturable, and the uptake and degradation curves were virtually identical. When macrophages were incubated with 125I-VLDL for 10 h in presence of BBA, the uptake and degradation of 125I-VLDL were still saturable. However, in absence of BBA, the uptake and degradation were no longer saturable. The results suggest that with macrophages incubated with VLDL for a shorter period, VLDL was taken up predominantly via receptor pathway, with a longer period of incubation, LPL played a striking role in uptake of VLDL.
