Osteoporosis has become a global public health problem, and dietary interventions may potentially be helpful in preventing this disorder.Salt ( sodium chloride) is one of the most important dietary nutrients.High sodium chloride intake may play an important role in bone metabolism.In this paper, we reviewed the effects of high sodium chlo-ride intake on bone mineral density, bone mineral content and bone biochemical markers, and analyzed the possible causes through currently available literature.Although there are a few inconsistencies results, we conclude a long-term high salt intake can reduce bone density or bone mineral content, change many biochemical markers of bone resorption, which may be caused mainly by increasing urinary calcium excretion and a low-grade metabolic acidosis.However, there are still many unclear aspects need further exploration.

Objective To understand the blood ABO,Rh blood group distribution of the main nationalities in Baoshan city to set up the local rare blood group donors archives for meeting the voluntary blood donor recruitment and the need of clinical blood use. Methods The ABO,Rh were detected by the microplate method.124 RhD negative individuals were extracted and screened for C/c,E/e by the test tube method.Results Among 7 main ethnic groups with blood donor,the ABO blood group distribution of Han, Yi,Bai,Lisu and Hui nationalities were A>O>B>AB;which in Brown and Dai nationalities were O>B>A>AB;the Rh negative ratio was 0.33% in Han,0.35% in Yi,0.09% in Bai,0.00% in Brown,0.32% in Lisu,0.21% in Dai,0.18% Hui;the Rh pheno-types were mainly ccdee (60.5%),Ccdee (33.1 %),CCdee (4.0%)and ccdEe (2.4%).Conclusion The distribution rate of ABO blood group in Han,Yi,Bai,Lisu,Hui blood donors in Baoshan was consistent with the distribution of Han population in China;Brown and Dai are different from Han in China;the Rh negative frequency is 0.00%-0.35%,which reflects the regional and na-tional characteristics of blood group distribution in baoshan city.

Vitamin D deficiency is highly prevalent in the general population including rheumatoid arthritis (RA) patients.Autocrine regulation of vitamin D modulates important immune response.Vitamin D deficiency may be involved in the pathogenesis of many autoimmune diseases including RA.Vitamin D regulates both the innate and adaptive immune responses.Vitamin D's effects on the innate immune system are mainly through the toll-like receptor and on the adaptive immune system through T cell differentiation,particularly the Helper T cell (Th) 17 response.As Thl7 cells are critical in the pathogenesis in RA,what effect will vitamin D deficiency lead to on the RA? Many data have indicated the relationship between vitamin D deficiency and RA disease activities,but not all the results are consistent.Here,we review the immune-modulatory roles of vitamin D and its effects on disease activity,osteoporosis and cardiovascular disease risk in RA.

Rcsult of field cultivation test by protoplastic fusion technique for biological cngln ering breeding of Poria cocos in Huoshan county, Anhui Province was reported for the first time. A fusion strain F1 was obtained from parents P1, P6578 by separation, fusion, marker of hypha protoplast and identification of recombinat. It was cultivated simultaneously with P1, P5778 for comparison. Results showed that the average cellal outputs were 1.73, 0.5 and 2.20kg respectively.As the output of strain F1 is intermediate between its parent P1 and P578, the result is considered to be unsatisfactory. The reason for such result was discussed.

Objective:To investigate the anti-proliferation effect of carvacrol on human gastric cancer cell BGC-823 and explore the molecular mechanism. Methods:The proliferation of BGC-823 cells was evaluated by MTT assay. Flow cytometry was used to ana-lyze the cell apoptosis after exposed to carvacrol. Transwell assay was used to analyze the effect of carvacrol on cell metastasis. Quanti-tative realtime-PCR was used to detect the expression of MMP-9 and TIMP-1. The expression of caspase-9 and PARP,and the activa-tion of ERK and P38 were detected by Western blot. Results:The incubation with carvacrol resulted in a significant inhibition of BGC-823 cell proliferation. After the treatment with carvacrol,the apoptotic rate was significantly increased( 0 μmol · L-1 vs 10 μmol · L-1 ,P<0. 000 1;0 μmol·L-1 vs 20 μmol·L-1 ,P<0. 000 1;0 μmol·L-1 vs 40 μmol·L-1 ,P<0. 000 1;0 μmol·L-1 vs 80μmol·L-1 ,P<0. 000 1)and the invasion ability was decreased(0 μmol·L-1 vs 80 μmol·L-1 ,P<0. 000 1). The expression of caspase-9(0 μmol·L-1 vs 80 μmol·L-1,P<0. 000 1)and TIMP-1 was increased(P<0. 000 1),PRAP fragment occurred(P<0. 000 1)and P38 signaling pathway was activated in the carvacrol treated group,while the expression of MMP-9 activity of ERK signa-ling pathway was inhibited(P<0.000 1). Conclusion:Carvacrol can inhibit cell growth and invasion,and induce cell apoptosis, which is closely related to MAPK signaling pathway.

Objective To compare the characteristics of connective tissue disease-associated interstitial lung disease (CTD-ILD) and idiopathic pulmonary fibrosis(IPF). Methods Patients with a diagnosis of ILD from June 2014 to December 2015 were selected in this study and patients with known other causes of ILD were excluded. The clinical manifestation, autoantibody, high resolution chest computed tomography (CT) and blood gas analysis were retrospectively analyzed. Results Six hundred and twenty-eight patients were included in this study. The prevalence of CTD-ILD and IPF were 459 (73.09%) and 169(26.91%) respectively. The age in IPF group was higher than that in CTD-ILD group:(67.10 ± 13.13) years vs. (52.10 ± 14.23) years, and there was significant difference (t =-10.092, P =0.000). The rate of male in IPF group was higher than that in CTD-ILD group: 75.15%(127/169) vs. 28.32%(130/459), and there was significant difference (P=0.000). Autoantibodies were commonly seen in CTD-ILD group and only antinuclear antibody, and anti-SSA antibody and anti-Ro-52 antibody were seen in IPF group. The most common chest images were honeycombing, bullae of lung and pneumonectasis in CTD-ILD group, while the presence of consolidation and small nodular shadow were more common in IPF group. The concurrence of respiratory failure was higher in IPF group compared with that in CTD-ILD group:49.11%(83/169) vs. 13.07%(60/459), and there was significant difference (P<0.01). Conclusions Patients with CTD-ILD and IPF possess distinct characteristics. Overall assessment of clinical manifestation, autoantibody serology, high resolution chest CT and other indicator will be conducive to the differential diagnosis and treatment of ILD.

AIM: The effects of YIGU capsule on proliferation and IGF-I mRNA protein expressions in osteoblasts were studied. METHODS: (1) Forty 12-month old Sprague-Dawley female rats were divided randomly into four groups (YIGU capsule high dose group, medium dose group and low dose group; saline group), the drug-containing serum and control serum were prepared.

OBJECTIVE:To study the effects of bone-tonifying capsule on bone morphology and serum TNF-?level of the osteoporosis(OP)model rats.METHODS:The rats were divided into sham operation group,model group and treatment group.OP model were established by removing ovaries of both sides in both the model group and the treatment group by o-variectomy,then the bone density of each group was determined;the bone morphology was observed in the decalcified section of bone tissue;the concentration of serum estradiol(E 2 )and TNF-?level were determined by radioimimunoassay.RESULTS:Compared with the sham group,the bone density and serum E 2 level lowed yet the TNF-?level increased in the model group(P

AIM: The effects of Yigu capsule on tartrate resistant acid phosphatase (TRAP) secretion and apoptosis in rat osteoclasts were investigated in order to further explore its mechanism of preventing and treating osteoporosis. METHODS: (1) Twenty-month-old Sprague-daweley rats were randomly divided into two groups(Yigu capsule group and saline group), and the drug-containing serum and control serum were prepared. (2) The newborn Sprague-daweley rat osteoclasts were cultured with different concentrations of Yigu capsule drug-containing serum. At different time point, TRAP activity was measured and the survival osteoclast was counted under reverse microscope.The percentage of osteoclast apoptosis was observed under fluorescence microscope after acridine orange staining. RESULTS: TRAP activity was lower and the percentage of osteoclast apoptosis was higher in drug-containing serum group than in control group at 24, 48 and 72 h( P
