Aim The relative bioavailability of domestic ibudilast sustained release capsules in healthy volunteers was observed.Methods A single oral dose of 20 mg of imported and domestic ibudilast sustained release capsules and 10 mg of ibudilast raw material was separately given to 12 healthy volunteers in a randomized crossover study. Ibudilast concentration in plasma was determined by HPLC method.Results The Cmax were (54.9?9.7),(60.7?9.1) and (62.2?11.5) ?g?L-1; the tmax were (3.8?0.8),(3.9?0.8) and (1.8?0.3) h;the t1/2(ke) were (1.5?1.4),(12.1?1.0) and (3.5?0.5) h,and the AUC(0～t) were (618.1?57.7),(588.1?66.6) and (233.0?46.4) ?g?h?L-1 in imported capsule group, domestic capsule group and raw material group respectively. The relative bioavailability of domestic sustained release capsules of ibudilast is (95.6?11.0)%. Conclusion The results of statistical analysis demonstrate that the imported and domestic sustained capsules have significant character of significantly sustained release and are bioequivalent.

Objective To investigate the effect of intraperitoneal injection of thalidomide on pain behaviors in a mouse model of bone cancer pain. Methods 36 male C3H/HeJ mice were divided randomly into tumor group (n= 18) and sham group (n= 18) ,six mice from each group were chosen to examine the time course of changes in behavior after tumor cells inoculated to the bone. 2 × 105 osteosarcoma NCTC 2472 cells were implanted into the intramedullary space of the right femurs of mice to induce ongoing bone cancer related pain behaviors. The sham group was inoculated by α-MEM without any cells. On the day before inoculation,the tumor mice were divided randomly into tumor + thalidomide group and tumor + vehicle group. The sham group mice were further divided randomly into sham + thalidomide group and sham + vehicle group. Pain ethology indexes such as paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL) were observed on 1 d before inoculation and on 3 d ,5 d ,7 d, 10 d, 14 d after inoculation. Results ( 1 ) At day 7 after the operation, compared with sham mice ( 1. 70 ± 0. 33 ) g, PWMT of tumor mice decreased to ( 1.07 ± 0. 30) g (P ＜ 0. 05 ). At day 10, PWTL shortened to ( 12.60 ± 1.69 ) s (P ＜ 0. 05 ) compared with sham mice ( 17.70 ± 1.54 ) s. And the pain behaviors of tumor mice were aggravated along with the development of cancer pain. (2) At day 7 after the operation, compared with tumor + vehicle group ( 1. 07 ± 0.39 ) g, PWMT of tumor + thalidomide group increased to ( 1. 53 ± 0. 39 ) g (P ＜0.05). At day 10, PWTL extended to ( 16.48 ± 1.13 ) s compared with sham mice ( 12.64 ± 1. 56) s (P ＜0. 05 ). Conclusion Intraperitoneal injection of thalidomide can efficiently relieve mechanical hyperalgia and thermal hyperalgia in a mouse model of bone cancer pain.

Objective To investigate the impact of accountable and kindred-like nursing and the practice of quality care.Methods 100 primiparas who gave birth three months before the accountable and kindred-like nursing were selected as the control group,while 100 primiparas who gave birth three months after accountable and kindred-like nursing were selected as the observation group.Tow groups' understanding of health education knowledge and skills,satisfaction with nursing when discharged,nomination rate of the most satisfactory nurse and compliance behavior after discharged were compared.Results In the observation group,62 cases had fully understood,28 had basically understood and 10 had not understood the health education knowledge when discharged,while in the control group the numbers were respectively 30,56 and 14.In the observation group,75 cases had fully understood,19 had basically understood and 6 had not understood the health education skills when discharged,while in the control group the numbers were respectively 28,58 and 14.The understanding of health education knowledge and skills were much better in the observation group than in the control group,and the differences were statistically significant (x2 =21.13,44.40,respectively; P ＜0.05).After being discharged,the compliance behaviors including pure breastfeeding,newborn massage and baby swimming of the observation group were also better than the control group (49 vs 27,58 vs 27,47 vs 18,respectively),and the differences were statistically significant (x2 =9.93,20.14,19.16,respectively; P ＜0.05).There were no significant differences in infant buttock nursing between two groups (P ＞ 0.05).The satisfaction of nursing and nomination rate of the most satisfactory nurse were also much higher in the observation group (99 vs 93,82 vs 53,respectively),and the differences were statistically significant (x2 =10.86,19.17,respectively ;P ＜ 0.05).Conclusions Accountable and kindred-like nursing can enhance the effect of health education,compliance behaviors,so as to improve the satisfaction degree of puerperants and their families with nursing service.

BACKGROUNDWe investigated the pathogenesis of atherosclerosis in diabetes, and detected the expression of scavenger receptor CD36 in monocytes in patients with type 2 diabetes.

METHODSAccording to the criteria by WHO, diabetic patients were classified into two groups: well controlled diabetic patients (WCP) and poorly controlled diabetic patients (PCP). The expression of CD36 protein and mRNA were evaluated by flow cytometry and reversal transcription polymerase chain reaction (RT-PCR). Plasma levels of accumulation of oxidized LDL (oxLDL) were directly measured by sandwich enzyme-linked immunosorbent assay (ELISA) method.

RESULTSFlow cytometry and RT-PCR showed that the mean fluorescence intensity (MFI) of CD36 in monocyte and CD36 mRNA were significantly higher in the PCP and WCP in comparison with healthy controls (P<0.01). CD36 MFI and mRNA in the PCP were increased by 78% and 36% compared to the WCP. In both groups, CD36 MFI and mRNA were significantly higher in patients with diabetic atherosclerosis in comparison with those without diabetic atherosclerosis (P<0.05). No significant difference was found in CD14 expression between the groups (P>0.05). The concentrations of plasma oxLDL were higher in the PCP group compared to WCP and control group (P<0.05), whereas oxLDL average values did not differ significantly between WCP and control groups (P>0.05). In the WCP and PCP groups, oxLDL levels were higher in patients with diabetic atherosclerosis than those without diabetic atherosclerosis (P<0.05).

CONCLUSIONSThe increased expression of scavenger receptor CD36 may be one of the mechanism of accelerated atherosclerosis in diabetic. The poorly controlled diabetes patients are at higher risk for the vascular complications than the well controlled diabetic patients.

OBJECTIVETo observe the correlation between brain-derived neurotrophic factor (BDNF) expression in the nerve system of diabetes mellitus (DM) rats and diabetic erectile dysfunction (ED).

METHODSDM rats were induced by injecting streptozotocin and erectile function test was done by injecting apomorphine (APO) at 1 month, 2 months, 3 months and 4 months. Then the brain, lumbosacral spinal cord, thoracic and lumbar sympathetic trunks, penis and prostate were taken from the diabetic and normal rats of the same age. The BDNF positive neurons and nerve fibers were shown by immunohistochemistry or fluorescence immunohistochemistry. The number and the grey density of BDNF positive cells and fibers were detected by image analysis.

RESULTSCompared with the control group, the erection frequency of the DM rats decreased at 2 months (P <0. 05) , and significantly at 3 and 4 months (P > 0.01) , and the BDNF positive neurons and nerve fibers in the cerebral cortex, lumbosacral spinal cord, thoracic and lumbar sympathetic trunks, penis and prostate of 1-month DM rats were reduced (P <0. 05). As time went on, BDNF declined progressively.

CONCLUSIONBDNF decreases in the central and peripheral nerve system in the early stage of diabetes mellitus, wich is closely correlated with diabetic ED.
