1.High salt intake and bone metabolism
Chinese Journal of Pathophysiology 2016;32(2):371-376
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.

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.

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.

Objective To investigate the effect of low 1evel laser treatment (LLLT) on periodontal clinical index,high-sensitivity C-reactive protein (hs-CRP) and metabolic control in patients of type 2 diabetes mellitus combined chronic peridontitis.Methods Nighty patients with type 2 diabetes combined chronic peridontitis were divided into three groups:initial periodontal therapy (group A),initial therapy combined with LLLT (group B) and control group (group C).The periodontal clinical parameters including periodontal probing depth (PD),clinical attachment loss (CAL),sulcus bleeding index (SBI),hs-CRP,HbA1c and fasting blood glucose (FBG) were tested before and at three months after therapy.Results The periodontal clinical parameters (PD,CAL,SBI) and hsCRP in group A and B improved significantly compared with that of group C after therapy (P<0.05),with group B had more significant difference (P<0.01).For the levels of HbA1c and FPG,group A and B showed downtrend,and more obvious outcome was detected in group B (P<0.05).Conclusions LLLT can effectively improve periodontal status,hs-CRP levels and metabolic control of patients with type 2 diabetes combined with chronic peridontitis,and thus to prevent the occurrence of diabetes complications.

Objective: To explore the effect of electro-acupuncture and musk injection on recovery of injured sciatic nerve function in rats, so as to provide the experimental evidences for the promotion of peripheral nerve regeneration by electro-acupuncture and musk injection.Methods: Following establishing rat model of sciatic nerve injury by operation, the rats were randomly divided into electro-acupuncture group, musk injection group, electro-acupuncture plus musk injection group and model group, then sciatic functional index (SFI) and motor nerve conduction velocity (MNCV) were measured after 4 weeks of treatment, 8 weeks of treatment and 12 weeks of treatment respectively to evaluate recovery of nerve function. Results: SFI and MNCV in electro-acupuncture group, musk injection group and electro-acupuncture plus musk injection group were improved more obviously than that in model group, with significant differences(P<0.01, P<0.05). Conclusions: Both electro-acupuncture and musk injection could promote recovery of injured nerve function, and they had a certain synergetic effect and might be the effective methods in promoting recovery of injured peripheral nerve function.

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.
