OBJECTIVEIn order to get the method for improving the salt resistance of Lycium ruthenium seeds and seedlings under NaCl stress, the seed germination and physiological characteristics of L. ruthenium seedlings was studied.
METHODSeveral physiological indexes of L. ruthenium seeds under NaCl stress, such as the germination rate (Gr), germination vigor (Gv), germination index (Gi), vigor index (Vi), and relative salt damage rate were measured. Other indexes of the seedlings like relative water contents (RWC) , chlorophyll contents, soluble protein contents, electrolyte leakage, the contents of malondialdehyde (MDA), and peroxidase (POD) were also measured.
RESULTNaCl at lower concentration could promote the seed germination but inhibit the seed germination at higher concentration. After the treatment by CaCl2 at the different concentrations, all germination indexes were increased. With the increase of salt concentration, the relative water contents and the contents of chlorophyll were decreased, the content of MDA and electrolyte leakage were increased. The change trend of POD activity showed the first increase and then decrease with the increase of salt concentration, which was similar to that of the soluble protein. After the treatment by CaCl2, relative water contents, chlorophyll and POD activities were decreased more slowly, and also electrolyte leakage and MDA contents increased slowly.
CONCLUSIONThe CaCl2 could significantly alleviate the damages to the seeds and seedlings of L. ruthenium under NaCl stress, and promote the salt resistance to the seeds and seedlings of L. ruthenium.

Objective The present study has been designed to investigate the impact of dietary iodine/sodium intake on blood lipid metabolism in mice. Methods According to body weight and gender, two hundred and sixty Balb/c mice were randomly divided into 2 groups including normal sodium group(Na) and low sodium group(LNa), with 130 animals per group. Each group were then randomly further divided into 5 sub-groups according to the amount of iodine intake: ① severe iodine deficiency(SID); ② mild iodine deficiency(MID); (③normal iodine (NI); ④ 10-fold high iodine ( 10HI ); (⑤ 50-fold high iodine (50HI), 10 groups in total, 26 per group.Eight months later, the body weight and the levels of urinary iodine, thyroid hormones and total cholesterol (TC),Results In Na group, the levels of TG and TC in male mice of SID group[ (1.64 ± 0.35), (3.88 ± 0.35 )mmol/L]and MID group[ ( 1.67 ± 0.31 ), (3.41 ± 0.66)mmol/L] were significantly higher than that of NI group[ ( 1.49 ± 0.42), (3.25 ± 0.47)mmol/L] and the levels of TG in female mice of SID group[(1.52 ± 0.22)mmol/L] were significantly higher than that of NI group[ (1.23 ± 0.22)mmol/L]. In addition, the levels of TG in male mice of 10HI and 50HI groups [ ( 1.16 ± 0.23 ), ( 1.21 ± 0.27 ) mmol/L ] were significantly lower than that of NI group [ ( 1.49 ± 0.42)mmol/L, all P < 0.05], the levels of TC in female mice of 10HI and 50HI groups[(2.37 ± 0.49), (2.48 ± 0.37)mmol/L] were significantly lower than that of NI group[ (2.84 ± 0.37) mmol/L, all P < 0.05 ]. In LNa group,the levels of TG and TC in male mice of SID group[ (1.39 ± 0.40), (3.33 ± 0.46 )mmol/L] were significantly lower than that of NI group [(1.30 ± 0.28), (3.00 ± 0.53) mmol/L, all P < 0.05], the levels of TG, TC and LDL in female mice of SID group[ (1.48 ± 0.26), (2.76 ± 0.43), (0.62 ± 0.22)mmol/L], the levels of LDL in female mice of MID group[ (0.60 ± 0.17 )mmol/L] were significantly lower than that of NI group[(l.22 ± 0.36), (2.51 ± 0.38),(0.48 ± 0.08), (0.48 ± 0.08)mmol/L, all P < 0.05], the levels of TG in male mice of 10HI and 50HI group [ (1.12 ± 0.22), (0.90 ± 0.11 )mmol/L] were significantly lower than that of NI group (all P < 0.05 ), the levels of TC in female mice of 10HI and 50HI groups[ (2.35 ± 0.34), (2.37 ± 0.37)mmol/L], the levels of LDL in female mice of 50HI group[(0.65 ± 0.18)mmol/L], were significantly lower than that of NI group(all P < 0.05). In Na group, the levels of thyroid hormones were distinctively decreased in SID group[TT4(0.00 ± 0.00)nmol/L, FT4 (0.93 ± 0.42)pmol/L, TT3(0.49 ± 0.07)nmol/L, FT3(2.86 ± 0.37)pmol/L] and MID group [TT4 (17.15 ± 15.26)nmol/L, FT4( 18.46 ± 4.31 )pmol/L, TT3(0.67 ± 0. 10)nmol/L, FT3(3.18 ± 0.24)pmol/L] compared with that of the NI group [TT4 (37.15 ± 15.26)nmol/L, FT4(28.46 ± 4.31)pmol/L, TT3(0.85 ± 0.10)pmol/L, FT3(3.87 ± 0.24)pmol/L, all P < 0.05 ].

Objective To observe the effects of iodine deficiency and iodine excess on the lipid metabolism in an experimental hypothyroid model of mice and to explore the roles of iodine independent of its role in thyroid hormones. Methods Female Balb/c mice were randomly divided into 6 groups: control, severe iodine deficiency (SID), mild iodine deficiency(MID), normal iodine (NI), 10-fold high iodine (10HI) and 50-fold high iodine(50HI), 10 in each group. The mice in control group were fed with low iodine forage, other mice were fed with low iodine forage containing 0.2% methylthiouracilum. All mice drank deionic water containing different concentrations of potassium iodide(KI). The iodine content in water was 326.79, 0, 196.08,326.79, 385621, 19 542.50 μg/L, respectively. After three months, thyroid hormones in the serum were determined by radioimmunoassay.Also, the blood samples were analyzed for total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesteiol (HDL-C) and low density lipoprotein cholesterol (LDL-C) and measured enzymatically by automatic analyzer. Results①The levels of Tr4 in SID[(21.27 ± 9.63)μg/L], MID[(23.41 ± 3.93)μg/L], NI[(22.57 ±4.66)μg/L], 10HI [(21.07 ± 5.03) μg/L] and 50HI groups [(21.46 ± 5.90) μg/L] were distinctively decreased compared with control group[(42.15 ± 8.26)μg/L, all P < 0.01]. There were no statistical significant differences of TT3 between different groups (F = 0.99, P > 0.05 ). ②The level of TG in 10HI group [ ( 1.17 ± 0.16)mmol/L ] was obviously decreased compared with control [(1.39 ± 0.22 )mmol/L] and NI groups[(151 ± 0.22)mmol/L, all P< 0.05].Both TG and TC in 50HI group[(1.18 ± 0.22), (1.78 ± 0.15)mmol/L] were significantly decreased compared with control [( 1.39 ± 0.22), (2.14 ± 0.37)mmol/L] and NI groups [(1.51 ± 0.22), (2.00 ± 0.15)mmol/L, all P < 0.05].The difference of serum HDL-C and LDL-C between the groups was not significant(F = 0.55,0.54, all P > 0.05 ).Conclusions Dietary iodine plays a role in the metabolism of serum lipids independent of thyroid hormones.Thus, monitoring the amount of iodine intake during sodium restriction should also be taken extremely important for effectively prevention and cure of cardiovascular disease.

The priority of the modernization of Chinese medicine at present is the standardization of Chinese medicine practice, including syndrome differentiation, disease diagnosis, standardized therapeutic program, etc. For this reason, the primary work is to establish a concise disease-syndrome differentiation and treatment system (CDSDTS) under the guidance of Chinese medicine theory, holding the core advantages and effectiveness of Chinese medicine, and aiming at creating a simplified theoretical and practical program facilitating for operation and spreading. It is not a mere simplification or careless reduction, but a normalized program of treatment according to the essence of Chinese medicine. Although the therapeutic effect might be somewhat lost, it can be widely approved, thereby, it would make contributions for the inheritance and development of Chinese medicine.
