Objective To observe the expression of phosphoinositide 3-kinase(PI3K) and protein kinase B1 (Akt1) in PI3K/Akt signaling pathway in rat bones with fluorosis, and to reveal the mechanisms of the skeletal fluorosis. Methods Thirty-six SD rats were randomly divided into 3 groups (control group, low-dose fluorosis group, high-dose fluorosis group) and 12 rats were in each group according to body weight. The rats were fed with different concentrations of fluoride (NaF) to establish fluorosis models. Controls were fed with tap water( < 0.5 mg/L), experimental animals in low- or high-dose groups were fed with water containing NaF 5.0,50.0 mg/L, respectively. Rats were sacrificed after 6 months of treating with fluoride and the serum was kept for testing the bone metabolic markers of none gla protein(BGP) and cathepsin K(Cath-K) by enzyme-linked immunosorbent assay(ELISA), the proteins and mRNA levels of PI3K and Akt1 in rat bones were detected by immunohistochemistry and real time PCR, respectively. Results Each group of serum BGP and Cath-k were compared, the difference was statistically significant(F = 73.45,39.36, all P < 0.05). The contents of BGP[(1.99 ± 0.62), (2.38 ± 0.16)μg/L] and Cath-K [(89.07 ± 19.66), (110.16 ± 9.81)pmol/L] in the low-and high-dose fluorosis groups were higher than those in the control group[(0.15 ± 0.03)μg/L,( 18.32 ± 2.27)pmol/L], and the high fluorosis group was obviously higher than the low fluorosis group (all P < 0.05). Each group of serum PI3K and Akt1 protein and mRNA were compared, the difference was statistically significant(F- 178.16,118.08,38.81,52.31, all P< 0.05). Compared to the control group (181.55 ± 4.24,188.46 ± 2.18,3.84 ± 1.69,4.33 ± 0.89), the protein and mRNA expressions of PI3K(171.66 ± 2.85,154.12 ± 4.15,11.31 ± 4.18,20.54 ± 6.68), Akt1(177.47 ± 3.16,156.42 ± 3.18,12.52 ± 3.13,19.43 ± 5.36) were higher in the low- and high-dose fluorosis groups (all P < 0.05), and the high fluorosis group was obviously higher than the low fluorosis group (all P < 0.05). Conclusions BGP and Cath-K contents could be used as bone metabolic indices in the endemic fluorosis disease. Fluoride can increase the expression of PI3K and Akt1 mRNA and protein in bone tissue of fluorosis rats, and PI3K/Akt1 signaling pathway may be involved in the pathogenesis of bone injury caused by fluoride.

Objective To investigate the association of promoter hypermethylation of secreted frizzled-related proteins (SFRPs) in patients with colorectal cancer. Methods The promoter hypermethylation of SFRPs in 20 sporadic colorectal cancer tissues and adjacent mucosa were detected by methylation-specific PCR. The amplified DNA was subcloned into the T-A cloning vector and sequenced. Two colorectal cancer cell lines (HCT116 and SW480) were treated with 5-aza-2' deoxycytidine for demethylation. The promoter hypermethylation and protein expression of SFRPs in colorectal cancer cell lines were detected by methylation-specific PCR and Western blotting. Results It was demonstrated that the hypermethylation of SFRP 1, 2, 4 or 5 was 19/20,17/20,3/20 or 13/20in cancer tissues, respectively, whereas it was 12/20, 8/12, 1/20 or 7/20 in adjacent mucosa,respectively. SFRP 1, 2 or 5 methylation was more frequently found in cancer tissue than in adjacent mucosa (P~0.05). Methylation of SFRP 1, 2, 4 and 5 were found in HCT116 cell line, but only SFRP1 and SFRP2 were found in SW480 cell line. There was a negative correlation between protein expression and methylation of SFRPs. The Western blotting revealed that SFRP protein re-expressedafter it treated with 5-aza-2' deoxyeytidine. Conclusion Methylation of SFRP 1, 2 or 5 gene is associated with the evolution of eolorectal cancer, and is closely related to silencing expression.

Objective To study the protective effect and its mechanism of anti-tumor necrosis factor-?antibody (TNF-? Ab) on lung injury after cardiopulmanary bypass(CPB).Methods Twenty-eight healthy rabbits were selected and randomly divided into four groups:group Ⅰ only received open chest operation;groups Ⅱ-Ⅳ underwent CPB.In the group Ⅳ,rabbit TNF-? Ab (2 400 pg/kg) was dropped into the intracheal tube before operation and just after releasing the aortic clamp.Saline was given to the group Ⅲ in- stead.Blood neutrophils count,TNF-?,MDA from the right and left atrium in the four groups were determined perioperatively.Water volume,TNF-? mRNA,TNF-? protein,apoptosis and pathomorphological changes were measured in the lung tissues.Results TNF- ? Ab can restrain leukocyte accumulation,reduce releasing of TNF-? and MDA in the lung.It can also reduce the occurrence of apop- tosis and attenuate pathomorphological changes in the lung tissue.However,it cannot reduce the secretion of TNF-? at the transcrip- tion level and protein level.Conclusion Intratracheal TNF-? Ab administration has markedly protective effect on lung injury after CPB.

Chinese Traditional and Herbal Drugs 2018;49(3):561-568
Objective To prepare a co-amorphous complex of piperine (PIP) and triterpenoids from Ligustri Lucidi Fructus (TLLF) to improve the dissolution of TLLF. Methods TLLF-PIP co-amorphous complex was prepared using solvent evaporation method. The microscopic structure of co-amorphous complex (CAC) was analyzed using differential scanning calorimetry (DSC), scanning electronmicroscopy (SEM), and powder X-ray diffraction (PXRD), the optimal ratio of the two components was investigated through the thermal stability experiment. Ultraviolet-visible spectrophotometry (UV-Vis) and high performance liquid chromatography (HPLC) were applied to determine the amount of TLLF, PIP and the individual components, ursolic acid (UA) and oleanolic acid (OA), respectively. The interaction of the optimal CAC was analyzed by Fourier transform infrared spectroscopy (FTIR), and its solubility and dissolution behavior in vitro were also studied to evaluate the formation of the preparation. Results PXRD analysis indicated that the TLLF-PIP-CAC with a mass ratio of 1:1 exhibited a stable amorphous state, which particles presented in near-spherical shape. FTIR results indicated that there are some hydrogen interactions between the moleculars of TLLF and PIP. The solubility and dissolution determination exhibited a pairwise released behavior with improved triterpenoids and decreased piperine dissolution. Conclusion The prepared TLLF-PIP-CAC can significantly improve the dissolution and amorphous stability of TLLF, which may provide a reference for the compatibility of insoluble compound in traditional Chinese medicine.

Objective:
To examine the association between serum vitamin D level and thyroid function indicators among elderly patients with type 2 diabetes mellitus (T2DM), so as to provide the evidence for the prevention and treatment of thyroid function abnormality among elderly patients with T2DM.
Methods:
Inpatients aged 60 years and older and admitted to the department of endocrinology of Zhejiang Hospital were selected as the study subjects. Gender, age, course of disease and other basic information were collected through questionnaire surveys. The serum 25-hydroxyvitamin D[25-(OH) D], thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), total triiodothyronine (TT3), and total thyroxine (TT4) were measured. The correlation between serum vitamin D level and thyroid function indicators in elderly patients with T2DM was evaluated by a multiple linear regression model.
Results:
A total of 402 elderly patients with T2DM were surveyed, including 210 males (52.24%) and 192 females (47.76%), and had a median age of 70.00 (interquartile range, 12.00) years and a median course of disease of 14.00 (interquartile range, 14.00) years. There were 162 patients with insufficiency of vitamin D (40.30%) and 182 patients with deficiency (45.27%). The levels of TSH and glycated hemoglobin in the vitamin D deficiency group were (2.34±1.66) μIU/mL and (8.83±2.14) %, respectively, which were higher than those in the normal group [(1.74±1.10) μIU/mL and (8.11±1.75) %; P<0.05]. The levels of FT3 and FT3/FT4 in the vitamin D deficiency group were (2.86±0.48) μIU/mL and 2.85±0.71, respectively, which were lower than those in the vitamin D insufficiency group [(3.09±0.47) pg/mL and 3.14±0.81, P<0.05]. Multiple linear regression analysis showed a negative correlation between 25- (OH) D and TSH (β'=-0.159, P=0.001).
Conclusion
The vitamin D deficiency may be associated with the increase of TSH level among the elderly patients with T2DM.
