Objective To study the changes of lipid levels and body weight during the treatment of bipolar disorder by lithium carbonate combined with olanzapine or lithium. Methods Lipid and body weight was measured in forty-six patients with bipolar disorder in the first six months (treated by lithium carbonate combined with olanzapine) and in the second six months (treated by lithium only). Then the results were compared with the data before the treatment. Results When the first six months was over,the levels of the total cholesterol, triglyceride and apolipoprotein B increased(P＜ 0.05 ) ,and when the second six months was over,the levels of the total cholesterol,triglyceride,low density lipoprotein cholesterol (LDL-C),and apolipoprotein B increased Significantly (P ＜ 0.05 ). The levels of the total cholesterol, triglyceride, LDL-C were more than the normal level,but apolipoprotein B didn't exceed the normal level. When the first six months was over, the body weight was higher than that before treatment [ (68.70 ± 8.35 ) kg vs. (64.85 ±7.52 ) kg, P ＜ 0.05 ]. When the second six months was over, the body weight [ (71.72 ± 7.96 ) kg ] was higher than that at the end of the first six months (P ＜ 0.05 ). Gender difference showed non-statistical significance.Conclusions The lipid levels and body weight will both increase whether treated with lithium carbonate combined with olanzapine or with lithium only. The lipid level changes apparently in treatment with lithium separately, and the risk of coronary heart disease will increase.

BACKGROUND: We have previously reported that marine algae polysaccharide derivant can significantly promote bone cell growth.OBJECTIVE: To observe the effect of marin algae polysaccharide derivant in treatment of osteoporosis.METHODS: Sixty female Wistar rats were randomly divided into control group, treatment group and model group. There were 20 rats in each group. The rats in treatment group and model group were respectively treated with retinoic acid to induce osteoporosis. The rats in treatment group were gavaged the marine algae polysaccharide derivant 10 mg/kg, and the rats in model group were gavaged the glucose 10 mg/kg orally for 14 days. Changes of rat femur bone histological examination and histomorphometry parameters were observed.RESULTS AND CONCLUSION: The mean Trabecular Number (Tb.N), the mean Trabecular Thickness (Tb.Th) and the percent Trabecular Area (Tb.Ar%) were significantly decreased in the model group compared with control group. The mean trabecular separation (Tb.Sp) was greatly increased. After intake of marine algae polysaccharide derivant, Tb.N, Tb.Th and Tb.Ar% of the treatment group were significantly more than that of the model group. The Tb.Sp was obviously reduced. These indicate that marine algae polysaccharide derivant can increase bone mass and have a therapeutic and preventional effect on the osteoporosis.

Purpose To study the expression of HPV L1 protein and p16 in various cervical lesions and to explore the value of HPV L1 protein and p16 immunostaining in predicting the progression from CIN1 to CIN3 and squamous cell carcinoma (SCC).Methods Expression of HPV L1 protein and p16 in 18 cases of CIN1, 9 cases of CIN2, 8 cases of CIN3 and 6 cases of SCC was detected by immunohistochemistry.Results The average positive rates of HPV L1 protein in cervical lesions were 26.8%, and HPV L1 protein was positive in 38.9% of CIN1 and 44.4% of CIN2, but in 0 of CIN3 and SCC. In contrast, the average positive rate of p16 protein in cervical lesions was 68.3%, p16 protein was positive in 38.9% of CIN1and 77.8% of CIN2, but in 100% of CIN3 and SCC. p16-/HPV L1+ and p16-/HPV L1- cases represented 61.1% of CIN1, but 0 of CIN3 and SCCs, whereas p16+/HPV L1- cases represented 100% of CIN3 and SCC.Conclusions Expression of HPV L1 protein decreases whereas p16 protein increases with lesion progression. p16+/HPV L1- cases have the potential for progression, whereas p16-/HPV L1+ and p16-/HPV L1- cases may not be progressive lesions or potentially in remission.

Objective To explore the influences of plumbagin on phosphatidylinositol 3-kinase (PI3K)/ protein kinase B (Akt) signaling pathway in rats with carbon tetrachloride induced liver fibrosis.Methods Forty male SD rats were assigned to control group,model group,2 mg/kg plumbagin treated group and 3 mg/kg plumbagin treated group,with 10 rats in each group.Rats of the control group were injected with 0.9％ NaCl solution (2 mL/kg) intraperitoneally,while rats of the other three groups were injected with 60％ carbon tetrachloride/peanut oil (2 mL/kg,3 times a week for 6 weeks) intraperitoneally.Since the third week after modeling,rats of plumbagin treated groups were treated with intraperitoneal injection of plumbagin at a dose of 2 mg/kg and 3 mg/kg (twice a week for 4 weeks),respectively.Serum levels of alanine aminotransferase (ALT),aspartate aminotransferase (AST),albumin (Alb) were monitored routinely.Hyaluronic acid (HA) and laminin (LN) were measured by radioimmunoassay after 6 weeks; protein expression of liver PI3K,Akt and phosphorylated Akt (p-Akt) were evaluated by Western blotting and immunohistochemistry,respectively.Comparison of means among groups was performed by univariate analysis of variance.Results The hepatic fibrosis model was successfully established after 6 weeks.Serum levels of ALT,AST,HA and LN of model group were significantly higher than those of control group (all P＜0.05).Serum levels of ALT,AST,HA and LN of 2 mg/kg plumbagin treated group and 3 mg/kg plumbagin treated group were significantly lower than those of model group,and the differences were statistically significant (all P＜0.05).The protein expressions of PI3K and Akt in each group were comparable (all P＞0.05).The p-Akt protein was mainly expressed in nucleus of hepatocytes.The levels of p-Akt protein in control group,model group,2 mg/kg plumbagin treated group and 3 mg/kg plumbagin treated group were 0.0821±0.0003,0.7374±0.0037,0.3679 ±0.0332 and 0.1327±0.0561,respectively,and that in model group was significantly higher than control group (t =851.302,P＜0.05),but those in plumbagin treated groups were both lower than model group (t=71.858 and 28.363,all P＜0.05).Conclusions Plumbagin presents anti-fibrotic effects in the liver,by down-regulating the expression of p-Akt during the development of fibrosis,which might be one of the antifibrotic mechanisms.

BACKGROUND:More and more evidence suggests that macrophages and inflammation reactions are involved in the formation and development of nephrolithiasis. Previous studies have found that calculi crystals can stimulate macrophages to release high mobility group protein B1.
OBJECTIVE:To investigate the synergistic effect of high mobility group protein B1 in calcium phosphate induced release of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 from human macrophages.
METHODS:(1) The induced U937 cells were respectively stimulated with RPMI (blank), 100 mg/L calcium phosphate, 100μg/L high mobility group protein B1 and 100 mg/L calcium phosphate+100μg/L high mobility group protein B1 for 1, 2 and 4 hours to col ect cellsupernatant. (2) The induced U937 cells were respectively stimulated with 100 mg/L calcium phosphate, 100 mg/L calcium phosphate+10μg/L high mobility group protein B1, 100 mg/L calcium phosphate+50μg/L high mobility group protein B1, 100 mg/L calcium phosphate+100μg/L high mobility group protein B1 for 4 hours to col ect cellsupernatant. Levels of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 were determined by ELISA.
RESULTS AND CONCLUSION:The levels of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 in the cellculture supernatant of 100 mg/L calcium phosphate group and 100μg/L high mobility group protein B1 group were both higher than those in the blank group in a time-dependent manner (P<0.05). The levels of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 in the cellculture supernatant of different concentrations of high mobility group protein B1 groups were al higher than those in the 100 mg/L calcium phosphate group in a concentration-dependent manner (P<0.05). The results suggest that both calcium phosphate and high mobility group protein B1 can induce the release of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 from human macrophages and the high mobility group protein B1 has the synergistic effect with calcium phosphate to induce interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 from human macrophages.
