Unlike modern acupuncture needles, the DZ is not inserted subcutaneously and is considered to be safe for common use, even at the bedside of terminally ill patients. In this case study, DZ application was selected and applied 14 times on a 92-year-old patient who had suffered severe oliguria along with administration of diuretics. Urine volume increased 12 out of 14 times following DZ treatment;however, the other two times it was ineffective. To investigate the reason and the differences in effective/ineffective DZ application, two internal conditions (effective vs ineffective) were compared by analyzing daily nursing reports (vital signs such as blood pressure, urine volume and body temperature) and weekly clinical data (including renal, liver and immune function, urea nitrogen, creatinine, ALT, AST, the ratio and number of leukocytes, erythrocytes). DZ application increased urine volume via a transient modification of the autonomic nervous system when internal homeostasis was maintained. Aging populations, who often have several diseases and medications, are rapidly increasing in developed countries. Therefore, the study and application of DZ may contribute to a reduction in medical costs, which have been rapidly and heavily expanding recently.展开更多

The effects of SLA.DQA gene on birth weight and 30-day-old weight were analyzed in 250 individuals of FI hybrid pig （ Heilongjiang wild boar x Beijing Black sow）. The analysis revealed four poly- morphic loci in the SLA-DQA gene, but only the Pvu II locus in exon 2 of SLA-DQA gene （ BB genotype） greatly increased the 30-day-old weight of piglets.展开更多

The instrument was applied to 285 individuals aged over 60 years (mean = 69.26, SD = 6.52). All participants completed a demographic data sheet, the WHOQOL-OLD, the Beck Depression Inventory (BDI), and the Geriatric Depression Scale (GDS);182 of the 285 participants also completed a quality of life questionnaire for diabetic patients (DQOL). Acceptable levels of reliability were found, with Cronbach’s alpha values between 0.70 and 0.90 for overall quality of life and all domains except for autonomy, where the alpha value was low. The exploratory factor analysis carried out to examine the construct validity of the instrument yielded six domains: sensory abilities, autonomy, past/present/future activities, social participation, death and dying, and intimacy (explained variance of 62.95%). The mean overall quality of life score was 94.86 (SD = 13.68, range 50 to 120). The WHOQOL-OLD module showed criterion validity and concurrent validity with respect to the BDI (r = -0.516, p = 0.034), the GDS (r = -0.336, p = 0.002), and the DQOL (n = 182, r = 0.159, p = 0.032). Discriminant validity was also confirmed with respect to self-perceived health (t = 2.701, d.f. = 225, p = 0.007) and education (F(3, 280) = 9.015, p p > 0.05). We conclude that the Mexican Spanish version of the WHOQOL-OLD module has adequate psychometric properties.展开更多

They constitute a violation of human rights, in particular because of their harmful consequences for the health of the people who suffer them and are the source of various complications. We report a case of FGM complications in the form of total coalescence of the labia majora with a small hole from which urine flows permanently. The management was a disinfubilation with suturing of the edges and urethral reimplantation and the evolution was favorable with complete healing after two (2) weeks.展开更多

Post-operative chest wall masses can also include infection, hematoma, seroma, cancer recurrence, metastasis, and lung hernia. Bedside ultrasound has been well documented to be beneficial in the differentiation of superficial pathology. Pleurocutaneous fistula is a pathologic communication between the pleural space and subcutaneous tissues of the chest wall. Pleurocutaneous fistula is a rare complication of tube thoracostomy, video-assisted thoracic surgery （VATS） procedures, and various pulmonary infections.展开更多

The two dips are at the 20th min and the 60 min, and the avoidance rates (AR) to the red bead in short- and intermediate-term memory are 68.4% on average, while that in the long-term momory was 74.8%. The OTPAT retained curve of day-old chicks hatching from hypomagnetic field space (experimental groups) presents the marked timing effect. The two dips were at the 25th min and the 50th min, the avoidance rates to the red bead (ARR) in the short- and intermediate-term memory was 74.1% on an average, which was resembled to that in control group; however, the long-term memory appeared an obvious fluctuation. Compared with that in control groups, ARR and the deviation coefficient in experimental groups were decreased by 25.3% and increased by 1.3 times, respectively. That is to say, both the memory ability and stability in the experimental chicks declined. The result shows that the hypomagnetic field space has a negative effect on the development of chick brain function, and that cannot be negligible.展开更多
