Hypoglycemia is a common and early metabolic disease of neonate.Serious and persistent hypoglycemia could result in brain damage.So far the pathogenesis of the disease is on research,but the definition of hypoglycemia,the glucose threshold of intervention,and diagnostic criteria of brain damage are still unclear.The pathogenesis of hypoglycemia is complicated.Brain damage may be related to the specific excitory amino acids receptors,reduced blood flow in occipital lobe,and cerebral hypoxia and ischemia.Diffusion weighted imaging of brain MRI and magnetic resonance spectroscopy are strongly recommended for the diagnosis of brain damage.Besides,clinical manifestation and cerebral function monitor are also included in the diagnosis.The threshold of intervention is suggested as serum glucose concentration with 2.2 ～ 2.6 mmol/L.

Objective To investigate the change of lung morphology and the mechanism in the brain-dead state. Methods Ten Ba-Ma mini pigs were randomized into 2 groups: brain-dead group (group B, n=5) and control group (group C, n=5). Brain-dead model was established in group B by increasing intracranial pressure in a modified, slow and intermittent way, and brain-dead state maintained for 24 h by respiration and circulation support. The serum TNF-?, IL-1?, and IL-6 were determined at 3, 6 12, 18 and 24 h after the initial confirmation of brain death. Lung tissues were taken at 24 h. The alterations of lung tissues were observed by HE staining, and the expression of PKC-? detected by immunohistochemistry. PKC-? mRNA at each time point was detected by RT-PCR. The microstructure of hepatic tissues was observed under an electron microscope. Results (1) Under the light microscopy, broadened lung alveolar septum, edematous, extravasate in the alveolar congestive capillary vessel, infiltration of lymphocyte were observed. Under the election microscopy, cytoplasm edema, swollen mitochondria of the type-Ⅱ epithelial cells, partial membrane dissolution of mitochondria were observed and the microtomentum disappeared. No obvious morphological injury was observed under light microscopy and election microscopy. (2) Compared with control group, the serum IL-1?, IL-6 and TNF-? in brain-dead group began to increase at 3 h after brain death, and become more and more higher when the maintained state was prolonged. The expression of PKC-? and PKC-? mRNA in brain-dead group was increased at 24 h in the lung tissue. Conclusion Brain death may evoke lung morphological injury and increase the level of inflammatory mediators; After brain death the levels of PKC-? mRNA transcription and protein translation is increased. The activation of PKC-? and the alteration of inflammatory mediators are supposed to be one of the mechanisms of the lung injury.

[Objective]To investigate the effects of alendronate(ALN)on subchondral bone and articular cartilage in the rat osteoarthritis model induced by anterior cruciate ligament transaction(ACLT).[Method]Twenty-four three-month-old female Sprague-Dawley rats were divided randomly into three groups:Sham group(n=8),ACLT+NS group(n=8) and ACLT+ALN group(n=8)(20 ?g?kg-1?2 d-1 subcutaneous injection for 12 weeks).Bone mineral density(BMD) measurement and bone histomorphometric analysis were made for the subchondral bone of right distal femur and proximal tibia in all rats at 12 weeks post surgery.Degree of cartilage degeneration was scored by Mankin scoring system.Immunostaining for matrix metalloproteinase 13(MMP-13) was performed to investigate the effect of ALN on cartilage matrix loss.[Result]BMD of the subchondral bone in the ACLT+NS group were significantly lower than those in the Sham group and the ACLT+ALN group(P

[Objective]To assess the protective effects of Xianlinggubao on articular cartilage and subchondral bone in experimental osteoarthritis induced by anterior cruciate ligament transaction (ACLT)in rabbits. [Methods]Thirty healthy Japanese white rabbits were divided randomly into three groups:sham group,ACLT+XLGB group and ACLT+ NS group. Rabbits in ACLT+XLGB group and ACLT+NS group received anterior cruciate ligament transection(ACLT)on the right knee. Rabbits in sham group received untreatment as control. ACLT+XLGB group received a daily administration of XLGB at a dose of 125 mg/kg of body weight for 6 weeks.In contrast,ACLT+NS group received saline at the same dose. All rabbits were sacrificed at 6 weeks after operation. The right femora were removed,measured for bone mineral density (BMD),and then were observed for the macro-pathologic changes with HE staining and graded by Mankin's scale. Expression levels of BMP-2 and MMP-13 were detected by immunostaining. The subchondral bone of right tibial plateau was cut and stained for the measurement of bone histomorphometry.[Results](1)The Mankin's score in ACLT+ XLGB group was significantly lower than that in ACLT+ NS group (P

Objective To investigate Hysterothylacium aduncum (Anisakidae) infection in marine fishes from Bohai Sea and Yellow Sea. Methods Nematodes were collected from the digestive tract of fishes, fixed with hot 4% formalin and preserved in 70% ethanol for study. The specimens were cleared in lactophenol for light microscopical examination, and properly treated for scanning electron microscopy (SEM). Results Among the fishes examined, 14 out of 93 species (15.1%) were found infected by H.aduncum, with a higher prevalence in the fish of Lophius litulon(66.7%), Scomber-omorus niphonius(47.5%), and Gadus macrocephalus(33.3%). H.aduncum infection was first recorded in elasmobranch-Raja smirnovi. Morphological differences of H.aduncum were observed, including the width of lateral alae and the length of intestinal caecum. Conclusion H.aduncum in fishes of Bohai Sea and Yellow Sea in China may be a complex species, and its high prevalence in some fishes reminds the risk of anisakiasis by eating raw fishes.

Objective To explore the kinds of Traditional Chinese Medicine(TCM)syndromes of depression to establish the criteria of common TCM syndromes of depression. Methods According to the ways of clinical epidemiology, TCM Bianzheng and syndromes’ indexes were investigated in 1977 depression patients with unipolar and bipolar affective disorder in 8 investigation sites such as Hunan, Tianjin, Beijing, Shenzhen, Guanxi, Hujian and Guizhuo. Results There were 12 kinds of syndromes in depression. According to order of composition ratio, the first four syndroms respectively were Gan-Yu-Qi-Zhi, Gan-Yu-Pi-Xi, Gan-Yu-Tan-Zu, Xin-Pi-Liang-Xu, the ratios of which were 29 7%, 24 5%, 13 4% and 12 8% respectively.Conclusions The common TCM syndromes of depression are such as the followings: Gan-Yu-Qi-Zhi, Gan-Yu-Pi-Xi, Gan-Yu-Tan-Zu, Xin-Pi-Liang-Xu. There are some relationships between common TCM syndromes of depression and 4 sub-types of unipolar disorder.

Objective To study the role of Ginsenoside Re and Rb3 on mice with viral myocarditis (VMC) and explore the mechanisms. Methods BALB/C mice were infected by coxsackievirus B3 ( CVB3) to establish VMC model. The mice were divided into control group,virus group and Ginsenoside Re and Rb3 treatment group(treatment group). On day 5,day 10,day 20 after infection,the level of serum crea-tine phosphokinase-MB( CK-MB) was detected. Then myocardial sections stained with Masson′s trichrome were used to observe the distribution of mice myocardial collagen fibers, quantify collagen volume fraction (CVF),and detect the levels of superoxide dismutase(SOD). Results (1)The level of CK-MB peaked on day 5,and decreased afterwards[day 5:(463. 68 ± 47. 62) U/L; day 10:(588. 81 ± 56. 09) U/L; day 20:(340. 48 ± 58. 22) U/L,respectively]. While the levels of CK-MB in treatment group were lower than those in virus group[day 5:(378. 69 ± 56. 02) U/L;day 10:(452. 56 ± 67. 78) U/L; day 20:(327. 13 ± 47. 20) U/L,respectively] in the same point. There were significant differences between groups on day 5 and day 10 (P<0. 01). (2) In viral group,the blue staining degree gradually increased with time in myocardial sections stained with Masson′s trichrome,especially in myocardial necrosis area. Compared with treatment group,CVF increased significantly in virus group on day 10 and day 20 ( day 10:6. 52% ± 2. 34% vs. 8. 94% ± 1. 67%;day 20:7. 00% ± 1. 53% vs. 10. 46% ± 1. 74%,P<0. 01). The levels of SOD in myocardial sections in virus group were lower than those of control group[day 5:(48. 83 ± 17. 74) U/L;day 10:(61. 41 ± 14. 58) U/L;day 20:(66. 26 ± 18. 97) U/L,respectively,P<0. 05],but in treatment group,the level of SOD could beimprovedsignificantly[day5:(72. 07 ±24. 85)U/L;day10:(83. 22 ±19. 52)U/L;day20:(92. 00 ± 20. 46) U/L, respectively, P < 0. 05]. Conclusion Because of the inhibition of oxygen radicals and oxidative stress, Ginsenoside Re and Rb3 can protect myocardial tissue. Ginsenoside Re and Rb3 can effectively reduce the extent of myocardial fibrosis. The mechanism may be related with the reduced peroxide level in vivo.
