BACKGROUND:Dexmedetomidine is an efficient, highly selective alpha-2 adrenergic receptor agonist, with sedative, analgesia and anti-anxiety effects, it has little impact on the respiration.
OBJECTIVE:To observe the analgesic effect induced by intrathecal injection of dexmedetomidine in rat model of spared nerve injury.
METHODS:A total of 60 male Sprague-Dawley rats were randomly divided into three groups (n=12):normal control group, dexmedetomidine group and saline group. Except for the normal control group, spared nerve injury model was established in the rats of dexmedetomidine group and saline group. Dexmedetomidine group was treated with intrathecal injection of dexmedetomidine 3μg/kg every day within 14 days after injury. Saline group was given equal volume of saline for 14 days. The thermal withdrawal latency and mechanical withdrawal threshold were measured respectively before injury, after injury, before injection, and 2, 7, 14 days after intrathecal injection. Four rats were sacrificed in each group at day 2, 7 and 14 after injection, and the lumbar segments (L 4-6 Hematoxylin-eosin staining was performed to detect the morphology of the spinal dorsal horn neurons and ) of the spinal cord were removed. Real-time RT-PCR and western blot analysis were used to determine the expression of protein kinase C mRNA and protein in the spinal dorsal horn neurons. immunohistochemistry staining was carried out to assess the expression level and distribution of protein kinase C.
RESULTS AND CONCLUSION:The thermal withdrawal latency and mechanical withdrawal threshold in dexmedetomidine group and saline group were significantly decreased compared with normal control group before or after injection (P<0.05). However, both the thermal withdrawal latency and mechanical withdrawal threshold in dexmedetomidine group after intrathecal injection were significantly higher than those in saline group (P<0.05). The protein kinase C expression in spinal dorsal horn neurons was significantly decreased in dexmedetomidine group compared with saline, and reached to the most lowest levels as normal control group on 14 days after injection. Moreover, the apoptosis of spinal dorsal horn neurons in dexmedetomidine group was lighter than that in saline group, and was similar to the morphology of neurons in normal control group on 14 days after injection. Intrathecal injection of dexmedetomidine could attenuate the hyperalgesia induced by spared nerve injury, which might be associated with the inhibition of protein kinase C expression in spinal dorsal horn.

BACKGROUND:Dexmedetomidine is an effective high-selectivityα2-adrenoceptor agonist that has sedative, analgesic, anxiolytic effects, but slightly affects respiration.
OBJECTIVE:To observe the analgesic effect of dexmedetomidine on selective damage of sciatic nerve branch in a rat model by intrathecal injection.
METHODS:A total of 36 male Sprague-Dawley rats were randomly divided into normal control group, physiological saline group and dexmedetomidine group. A rat model of selective damage of sciatic nerve branch was established by knotting off the common peroneal nerve and tibial nerve in the physiological saline group and dexmedetomidine group. Rats in the dexmedetomidine group were daily injected with dexmedetomidine 3μg/kg by intrathecal injection within 14 days after injury. Rats in the physiological saline group were injected with physiological saline.
RESULTS AND CONCLUSION:Compared with the physiological saline group, the mechanical withdrawal threshold and the thermal withdrawal latency were significantly increased in the dexmedetomidine group (P<0.05). Neuronal nitric oxide synthase mRNA and protein expression levels were significantly decreased in the spinal dorsal horn (P<0.05). The injury to spinal dorsal horn neurons was obviously lessened. Moreover, neuronal nitric oxide synthase mRNA and protein expression levels and the injury to spinal dorsal horn neurons were similar between 14 days after administration and normal control group. Results indicated that intrathecal injection of dexmedetomidine could inhibit the expression of neuronal nitric oxide synthase in the spinal dorsal horn and relieve the pain induced by sciatic nerve injury.

Objective To investigate and analyze cognitive similarities and differences of nurses factors that lead to the tense nurse-patient relationship from both attitudes of nurses and patients. Methods By using the method of questionnaire, 284 nurses and 305 patients were investigated respectively in a top'three hospital of a city. Results There was a significant difference in cognitive scores of nurses factors that lead to the tense nurse- patient relationship (P < 0.01), patients' scores were (3.90±0.47) points which were higher than (3.52±0.35) points of the nurses′. In dimensions of prioritization, both nurses and patients believed that technical ability, professional knowledge and service attitude were the main factors leading to the tense relationship between nurses and patients. While nurses held that communication ability was more important, patients held that the nurse′s own personality was more important. Conclusions There are similarities and differences of attitudes to nurs's factors between nurses and patients regarding tension in nurse- patient relationship. The tense relationship between nurses and patients is affected to a great extent by nurses' professional knowledge, technical ability and service attitude. Managers should objectively evaluate and fully pay attention to cognitive similarities and differences of both sides, strengthen nurses′theoretical knowledge and clinical skills training, improve service attitude, and develop good character,in order to provide high quality nursing service for patients.

Objectve To investigate the association between insertion/deletion (I/D) polymorphism of angiotensin converting enzyme (ACE) gene and autosomal dominant polycystic kidney disease (ADPKD). Methods Polymorphism of ACE gene was analyzed by polymease chain reavtion (PCR) in 103 ADPKD patients and 16 ADPKD family constellations including 35 patients and 30 non-ill people. Clinical data were collected and age of onset, hepatocyst, hypertension, urinary tract infecton, urinary concretion, hematuria were used as the main parameters to analyze the association between ACE gene polymorphism and ADPKD. Results The age of onset in DD genotype was 7.2 years younger than that in DI genotype [(31.90±11.41) vs (39.10±10.08) years, P<0.05] and was 14.25 years younger than that in Ⅱ gene type [(31.90±11.41) vs(46.15±14.74) years, P<0.05]. The age of onset in I/D genotype was 7.05 years younger than that in Ⅱ genotype [(39.10±10.08) vs (46.15±14.74) years, P<0.05]. There were significance differences of main clinical symptoms (hypertension, hematuria and urinary tract infection) among three genotype groups. In 11 family constellations, ACE gene polymorphism presented genetic linkage, but without significant difference (P>0.05); the genotype distribution was not significantly different between ADPKD and non-ill people (P>0.05), as well as between man and woman (P>0.05); the DD genotype frequency was significantly higher in ADPKD patients with chronic renal failure (P<0.05). Conclusions The age of onset in DD gentype is the youngest among three groups. The incidence of hypertension and hematuria in DI genotype is the highest. The ACE gene polymorphism in ADPKD family constellation does not provide diagnosis information. The ACE gene I/D polymorphism may not contribute to ADPKD. The DD genotype of ACE may be a risk factor of renal failure in the ADPKD.
