AIM: To investigate the effect for Chinese herbal recipe exctract for replenishing kidney and activating blood circulation (CRERKABC) on cell proliferation, differentiation and mineralization in cultured rat osteoblasts. METHODS: Osteoblasts from craniums of newly born SD rats were cultured in vitro , and the third-passage osteoblasts were exposed to CRERKABC(20 mg/L, 40 mg/L, 80 mg/L) and vehicle, respectively. MMT was used to assess ability of cell proliferation. Activity of akaline phosphatase was assayed by p-nitrophenyl picolinate, and content of osteocalcin in suppernatants was examined by radioimmunoassay. In addition, alizarin bordeaux staining method was used to count mineralzation nodes under optical microscope. RESULTS: ①CRERKABC increased the proliferation of osteoblasts in a dose and time-dependant manner. ②Akaline phosphatase(ALP) activity and osteocalcin content were also increased in CRERKABC-treated groups at 48 h , 72 h, 96 h, except ALP in low concentration CRERKABC group at 48 h( P0.05 ). CONCLUSION: CRERKABC can promote proliferation, differentiation, maturation and mineralization of the osteoblasts cultured in vitro.

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.

AIM:To analyze the regulatory effect of Yigu capsule on core binding factor alpha 1 (cbf ?-1) gene expression in bone of ovariectomized osteoporosis (OP) rats. METHODS: Thirty-six 10-month old Sprague-Dawley female rats were randomized into three groups: sham-operated group, model group and drug group. After intervention by the corresponding methods, the femurs were collected, SYBR green Ⅰ fluorescence quantitative PCR technique was applied with the internal control of GAPDH according to the relative quantitative formula (2-Ct), the differentially expressed multiples between the model group or drug group and sham-operated group were calculated. RESULTS: Quantitative formula analysis showed that the level of cbf ?-1 gene expression in bone of model groups was decreased than that in sham-operated rats [compared with sham-operated group, P0.05). CONCLUSION: The results of this study show that cbf ?-1 gene expression in bone tissue of ovariectomized OP rat is decreased, and Yigu capsule increases the level of cbf ?-1 gene expression in bone of OP, indicating that Yigu capsule induces bone marrow mesenchymal stem cells into osteoblasts.

One of the hallmark features of children with autism is language barrier,which mainly manifested with lack of visual contact and attention,imitation speech,broad pronunciation problems,poor understanding abilities to speech and abstract questions,deficiency of logicality,spoken language disorder,confusion about the usage of pronouns such as you,I and she or he,etc.According to the basic principles of language training,visual perception tracing,vision contact,cultivation of communication desire,auditory and understanding training can all be used to make children with autism to understand the relationship between pronunciation and words,try to pronounce syllables,make good preparation for valid pronunciation in the early stage of language training.Respiration training,point massage of oral surface and valid usage of pronunciation organs' practice can help them to say phrase and simple sentences gradually.They can say a sentence correctly and achieve the destination of grasping language through learning decorative words and enhancement of understanding and logic abilities.Very efficient result could be approached through correct evaluation,found existing problems and using correct training methods during language training of children with autism.

Objective To study the clinical effects and mechanism of Xuebijing injection combined with antibiotics in the treatment of severe lung infection in ICU.Methods 110 cases of ICU severe lung infection were randomly divided into control group(55 cases) and observation group(55 cases).The control group was administered with cefotaxime sodium and sodium benzene azole penicillin,while the observation group was co-administered with Xuebijing injection and cefotaxime sodium,sodium benzene azole penicillin.All treatment lasted for 7 days.Meanwhile,the serum levels of C-reactive protein (CRP),TNF-α,IL-6,COX-2 and SOD were measured before and after the therapy.Results After treatment,the levels of CRP and TNF-α,IL-6 were significantly reduced in the two groups[after treatment CRP,TNF-α,IL-6 levels of the control group:(46.50 ± 17.74) ng/L,(339.50 ± 112.61) ng/L,(141.20 ± 42.66) ng/L;and those in the observation group:(35.60 ± 16.89) ng/L,(268.20 ± 98.47) ng/L,(118.70 ± 39.81) ng/L;the control group:t =7.329,9.682,6.038;the observation group:t =11.012,14.335,14.335,all P ＜ 0.01],and the reduced amplitude of the observation group was significantly lower than that of the control group (t =3.300,P ＜ 0.01).The serum levels of COX-2 and SOD were significantly reduced [after treatment COX-2 and SOD levels of the control group:(189.50 ± 34.52) ng/L,(203.60 ± 67.26) U/mL;those of the observation group:(118.20 ± 25.36) ng/L,(162.30 ± 59.78) U/mL;COX-2:the control group:t =15.021,P ＜ 0.01;the observation group:t =32.931,P ＜ 0.01;SOD:the control group,t =4.183,P ＜ 0.01;the observation group,t =7.682,P ＜0.01],and the reduced amplitude of the observation group was significantly lower than that of the control group(t =3.404,P ＜0.01).Conclusion Xuebijing injection combined with antibiotics in the treatment of severe lung infection in ICU has good effects,which is due to the inhibition of COX-2 and SOD to improve inflammation and oxidative stress damage in cells.

For the purpose of detecting the polymorphism of the human eighth complement component(C8A),an allele specific amplification method were established for detecting two alleles of C8A based on a nucleotide exchange of the C8? cDNA sequence.100 DNA blood samples from unrelated individuals of Han population in Chengdu were typed by this method.The result of comparison with the data of protein typing of the same samples using SDS PAGE method proved that the described method is efficient,correct and reliable for C8A genotypes.This methtod is valuable for further application in population genetic study and forensic science practice.
