Objective To investigate effect of different doses of propofol infusion on serum lipid metabolism and pulmonary function in patients with cervical cancer operation.Methods 120 patients with cervical cancer were randomly divided into A, B, C three groups, 40 cases in each group, were treated with laparoscopic cervical cancer radical operation, the 4 mg/(kg· h), 6 mg/(kg· h), 8 mg/(kg· h), and the pulmonary function and lipid profiles were detected.Results Compared with the B and C groups, the recovery time and the the awake time of the patients in B ,C group was shorter (P<0.05).The recovery time and the the awake time of the patients in A group had not significantly different.Compared with before operation, TG, TC and LDL levels were elevated, HDL decreased in theree groups after the operation(P<0.05);compared with the A and B groups, the levels of TC, LDL, TG and were higher, the level of HDL were lower (P<0.05),there were no significant differences in level of TC, HDL, TG and LDL between group A and group B;there was no significant difference between P(A-a) O2 and RI among three groups before surgery, P(A-a) O2 and RI levels were elevated in the three groups after surgery(P<0.05), compared with the A and B groups, P(A-a)O2 and RI levels in group C were lower(P<0.05), there was no significant difference in P(A-a)O2 and RI between group A and group B.Conclusion 4 mg/(kg· h)of propofol can significantly shorten the recovery time and awake time, improve the level of lipid metabolism and pulmonary function.

ObjectiveTo explore the role of the lymphocyte subsets in the peripheral blood in diagnosis, treatment and prognosis of hemophagocytic lymphohistiocytosis (HLH) in children.MethodA total of 30 children with HLH were enrolled in this study and treated according to the HLH-2004 diagnostic guidelines. 20 children with HLH entered complete remission (CR) and 10 children with HLH died. Thirty age-matched healthy children were selected as normal controls. T cell subsets in the pe-ripheral blood were measured by lfow cytometry.ResultsCompared with control group, CD3+T and CD8+T cells were signiif-cantly increased, CD4+T and CD3-CDl6+CD56+ NK cells were signiifcantly decreased, and CD4+/CD8+ cell ratio was signiifcantly decreased in 20 CR children and 10 died children with HLH in acute phase (P<0.05). CD19+B cells was not statistically different in 20 CR children and 10 died children with HLH in acute phase from control group (P>0.05). In acute phase, the lymphocyte subsets were not statistically different between 20 CR children and 10 died children (P>0.05). In 20 CR children, the proportion of CD3-CD16+CD56+NK in CR phase was statistically different than that in acute phase (P<0.05).ConclusionsChildren with HLH have obvious changes in peripheral blood lymphocyte subsets and have cellular immunity disorders. Dynamic detection of the changes may help determine the therapeutic effect and prognosis of HLH.

Objective To observe microvascular architecture and free radical metabolism in hippocampus after focal cerebral ischemia/reperfusion and to explore the effect of NBP (3-n-butylphthalide). Methods Fifty-four SD rats were ran?domly divided into NBP pretreatment group, ischemia/reperfusion group and sham operation group (n=18 in each group). The model of middle cerebral artery occlusion(MCAO)was established by suture method. The neurological scores were counted and the volume of infarction was measured;TA-Fe method was applied to observe the microvascular architecture of hippo?campus, Mivnt image analysis system was used to analyze the microvessel density(MVD)and the microvessel area density (MVA)of hippocampus quantitatively;The activity of SOD and content of MDA were measured by colorimetric method. Re?sults Compared to the ischemia reperfusion(IR)group, the neurological scores and the volume of infarction were decreased sharply in NBP group. What′s more, the activity of SOD, MVD and MVA were all enhanced but the content of MDA and the count of closed microvessels were both reduced(P < 0.01). Conclusion NBP can improve microvascular architecture of hippocampus and reduce the free radical injury. There is a protective effect on hippocampus of rats who suffered focal cere?bral ischemia reperfusion.

BACKGROUND/OBJECTIVES: Inonotus obliquus has been used as antidiabetic herb around the world, especially in the Russian and Scandinavian countries. Diabetes is widely believed to be a key factor in Alzheimer’s disease (AD), which is widely considered to be type III diabetes. To investigate whether I. obliquus can also ameliorate AD, it would be interesting to identify new clues for AD treatment. We tested the anti-AD effects of raw Inonotus obliquus polysaccharide (IOP) in a mouse model of AD (3×Tg-AD transgenic mice).MATERIALS/METHODS: SPF-grade 3×Tg-AD mice were randomly divided into three groups (Control, Metformin, and raw IOP groups, n = 5 per group). β-Amyloid deposition in the brain was analyzed using immunohistochemistry for AD characterization. Gene and protein expression of pertinent factors of the ubiquitin-proteasome system (UPS) was determined using real-time quantitative polymerase chain reaction and Western blotting. RESULTS: Raw IOP significantly reduced the accumulation of amyloid aggregates and facilitated UPS activity, resulting in a significant reduction in AD-related symptoms in an AD mouse model. The presence of raw IOP significantly enhanced the expression of ubiquitin, E1, and Parkin (E3) at both the mRNA and protein levels in the mouse hippocampus. The mRNA level of ubiquitin carboxyl-terminal hydrolase isozyme L1, a key factor involved in UPS activation, also increased by approximately 50%. CONCLUSIONS Raw IOP could contribute to AD amelioration via the UPS pathway, which could be considered as a new potential strategy for AD treatment, although we could not exclude other mechanisms involved in counteracting AD processing.

Objective To establish and evaluate chemotherapeutic phlebitis model rats induced by vinorelbine via the dorsalis pedis vein.Methods Rats were divided randomly into control and 4 different concentration of vinorelbine-induced model groups.Control rats were injected with 0.1 mL normal saline via the dorsalis pedis vein of the hind limb,while other rats were injected with different concentrations of vinorelbine(2,3,4,5 mg/mL),as above.General observations were performed and the hind limb volume was measured daily for 7 consecutive days to calculate the swelling rate.The rats were then killed and histological changes in the dorsalis pedis vein were observed by hematoxylin and eosin staining.Microstructural changes on the surface of the vascular endometrium were observed by scanning electron microscopy.Results Injection of 2,3,4,5 mg/mL vinorelbine via the dorsalis pedis vein significantly induced hind limb swelling in a concentration-dependent manner,peaking on day 3 in each group.The phlebitis rates on day 7 were 50%in the 2 mg/mL group and 83.3%in the 3 mg/mL group.Phlebitis was also induced in the 4 mg/mL and 5 mg/mL groups,including grade Ⅲ in 66.6%and grade Ⅳ in 83.3%.Histopathology showed inflammatory cell infiltration,wall thickening,lumen stenosis,and thrombosis in the tissues surrounding the veins.Scanning electron microscopy showed destruction of tight junctions of venous endothelial cells,and a rough surface of the vascular lining,resultsing in blood cell adhesion.Conclusions Injection of 0.1 mL of 3～5 mg/mL vinorelbine via the dorsalis pedis vein could induce red,swollen,and cord-like veins,as well as infiltration of inflammatory cells around the vein,thickened vein walls,lumen stenosis,and thrombosis.In addition,the surface of the venous intima was rough and adhered to numerous blood cells.All these features are consistent with those of clinical chemotherapeutic phlebitis in terms of the symptoms and pathological structure.

Objective: To describe the status of cognition about colorectal cancer and the screening and its relevant factors among first degree relatives of hereditary colorectal cancer patients in Guangzhou. Methods: Totally 274 subjects were investigated by a self-designed demographic questionnaire and the Chinese version of Cognitive Questionnaire for Colorectal Cancer and were analyzed by chisquare test, rank sum test and logistic regressive. Results: 60.2% (165/274) cases had a high level of cognition about colorectal cancer, 23.7% (65/274) had middle level of cognition about colorectal cancer and 16.0% (44/274) had a low level of cognition about colorectal cancer. Multivariate logistic regression analysis showed that age, sex, degree of education, marital status, family income, medical insurance and the number of cancer patients in his family were related factors (P<0.05). People who were young, female, highly educated, high family income, single, public/urban health insurance, commercial insurance and with more than 4 relatives suffering from colorectal cancer have higher cognitive level. Conclusions The level of cognition about colorectal cancer among first degree relatives of hereditary colorectal cancer patients was a little high. Medical staff should pay attention to relevant factors of health belief in subjects and develop targeted intervention to improve the level of cognition among these subjects and to promote their screening behavior.

Beijing has been one of the epicenters attacked most severely by the SARS-CoV (severe acute respiratory syndrome-associated coronavirus) since the first patient was diagnosed in one of the city's hospitals. We now report complete genome sequences of the BJ Group, including four isolates (Isolates BJ01, BJ02, BJ03, and BJ04) of the SARS-CoV. It is remarkable that all members of the BJ Group share a common haplotype, consisting of seven loci that differentiate the group from other isolates published to date. Among 42 substitutions uniquely identified from the BJ group, 32 are non-synonymous changes at the amino acid level. Rooted phylogenetic trees, proposed on the basis of haplotypes and other sequence variations of SARS-CoV isolates from Canada, USA, Singapore, and China, gave rise to different paradigms but positioned the BJ Group, together with the newly discovered GD01 (GD-Ins29) in the same clade, followed by the H-U Group (from Hong Kong to USA) and the H-T Group (from Hong Kong to Toronto), leaving the SP Group (Singapore) more distant. This result appears to suggest a possible transmission path from Guangdong to Beijing/Hong Kong, then to other countries and regions.
