This infant cereal chiefly consisted of rice meal, fullfat milk powder, rice germ and dried yeast, and fortified with ferrous lactate and calcium carbonate. This mixture contained 14.1% protein, 8.6% fat, 64.3% carbohydrate, 750mg% calcium, 10mg% iron, 1.0mg% zinc and proper amount of various kinds of vitamins.1. Growth test; 84 weaning SD rats were randomly divided into 6 groups:(A) Infant cereal group;(B) Control I; (C) Control II; (A') Infant cereal group; (B') Control I; (D) Casein group. The latter three groups contained 10% protein which were designed for calculating PER. All these different preparations were fed to 6 groups for 4 weeks. The results showed that the body weight gain, the FE, CE and PER were not significantly different between group A and B but there were significant difference between group A and C. The Hb was increased from 11.76g% ( ) and 11.46g%() to 14.30g% and 14.46g% respectively in group A. The bones developed well and no decalcification occured.2.Nitrogen balance test:(A). Infant cereal group; (B) Control I. The results indicated that the TD, BV and NPU of group A were 98.08%, 85.73% and 84.09% and of group B were 97.81%, 87.51% and 85.59% respectively. Both groups obtained the results of positive nitrogen balance, no significant statistical difference. The contents of hepatic and body nitrogen of two groups were also not significantly different.These data demonstrate that this infant cereal is able to promote the growth of weanling rats, to retain positive body nitrogen and to prevent the occurrence of anemia and rickets.

Objective To establish a novel model of senile dementia in rats. Methods Fifty-two Wistar male rats were divided into 5 groups, group A was treated with a permanent bilateral occlusion of both carotid arteries (2-VO) first and then intraperitoneal injection of D-galactose (60 mg?kg -1 ?d -1 ,ip,42 d), group B with intraperitoneal injection of D-galactose (60 mg?kg -1 ?d -1 ,ip,42 d) first and then permanent bilateral occlusion of both carotid arteries, group C with 2-VO, group D with intraperitoneal injection of D-galactose, and group E (normal control) without the above treatment. All the rats were tested by using Morris water maze for their performance in learning and memory. Results Wistar rats treated with both 2-VO and D-galactose presented a significant diffe-rence from those simply treated by 2-VO and the normal rats. Conclusion The rat model of senile dementia induced by 2-VO and D-galactose simulated some characteristics of human senile dementia, and might be used in basic experiment study of senile dementia, such as vascular dementia, Alzheimer′s disease and mixed dementia.

BACKGROUND:Studies have shown that Wnt signaling pathways play an important role in the osteogenic differentiation of mesenchymal stem cells.
OBJECTIVE:To review the mechanism and regulation of the Wnt signaling pathways, as wel as Wnt signaling pathway effects on osteogenic differentiation of mesenchymal stem cells.
METHODS:A computer-based search of PuMed database and CNKI database from September 1998 to March 2013 was performed to search related articles. The key words of“Wnt, mesenchymal stem cells, Wnt signaling pathways, osteoblastic differentiation, canonical wnt signaling pathway, non-canonical signaling pathway”in English or Chinese were used to search the articles in the title and the abstract. A total of 31 articles were included to review.
RESULTS AND CONCLUSION:Wnt signaling pathways play a critical role in the osteogenic differentiation of mesenchymal stem cells. Canonical Wnt signaling pathway, non-canonical Wnt signaling pathway, and their mutli-factors were involved in regulating the proliferation and differentiation of mesenchymal stem cells. The osteogenic differentiation of mesenchymal stem cells can be promoted effectively via specific induction of Wnt signaling pathways. Wnt11, FZD6, sFRP2, sFRP3 and Ror2 expressions increase, while Wnt9a and FZD7 decreases during the regulation. However, the relations of factors in Wnt signaling pathways and how to use the mechanism of Wnt signaling for promoting mesenchymal stem cells faster, more accurate differentiation need further studies.

AIM: To examine the effects of cigarette smo ke extract (CSE) and lipo polysaccharide (LPS) on the production of transforming growth factor-? 1 (TGF- ? 1 ) mRNA and protein in cultured human embryonic lung fibroblasts (HELF). METHODS: The cultured HELF were incubated with CSE, LPS or CSE in com bination with LP S for 24 hours at 37℃, respectively. The total RNA was extracted from the cells . The expression levels of TGF-? 1 mRNA were evaluated by reverse transcription - p olymerase chain reaction (RT-PCR). The mRNA levels of TGF-? 1 were corrected by GAPDH transcripts, and TGF-? 1 protein levels were determined by immunocytoch emistry. RESULTS: CSE stimulated the TGF-? 1 mRNA expression i n HELF at lower concentr ati ons (1∶50 and 1∶25)( P 0.05). LPS enhanced TGF-? 1 mRNA levels in HELF at a ll three doses (0.1 mg/L, 1 mg/L, and 10 mg/L)( P

Objective: To observe clinical therapeutic effective of 5 mono nitre isosorbide combined with ginkgo leaf in the treatment of angina pectoris. Methods:100 cases of angina pectoris were randomly divided into control group (5 mono nitre isosorbide) and treated group (5 mononitre isosorbide combined with ginkgo leaf). The therapeutic course lasted four monthes. Results: Nitroglycerin consumption in treated group was lower significantly than that in control group. The effective rate was 94.8% in the treated group and 84.2% in the control group after four monthes ( P

Objective To detect the serum prohibitin protein(PHB)level in children with renal interstitial damage and analyze the correlation between PHB and renal interstitial fibrosis(RIF). Methods Serum PHB protein levels were determined by Western blot analysis in 36 children with kidney diseases,and 30 healthy children were studied as control. Levels of BUN,Scr,and urinary microprotein series(including ALBU/Cr,NAGU/Cr,IgG U/Cr,α1-MU/Cr)were studied by automatic biochemical analyzer. Renal interstitial damage was semiquantitatively graded according to Katafuchi's method. The correlation between serum levels of serum PHB protein and those of BUN,Scr as well as urine microprotein were analyzed. Results Serum PHB protein was positive in children with diverse kidney diseases however it was negative in the normal controls(P < 0.05). Serum PHB levels were significantly higher in children with proliferative glomerulonephritis than those with non-proliferative glomerulonephritis(P < 0.05). Statistical analysis indicated that serum PHB levels positively correlated with the degree of tubulointerstitial lesions(r = 0.868,P < 0.001)as well as the glomerular injuries(r = 0.753,P < 0.001). And,serum PHB levels were also positively correlated with urinary microprotein including NAG(r = 0.586,P < 0.001)and IgG(r = 0.341,P < 0.001). Conclusions Serum PHB levels were significantly increased in children with kidney diseases and were positively correlated with the degrees of renal interstitial damage,suggesting that PHB might be a potential clinical marker for detecting tubulointerstitial lesions.

Objective To compare the effect of the rehabilitation training during or after acupuncture on edema and pain of shoulder-hand syndrome after stroke. Methods 60 patients with shoulder-hand syndrome were divided into two groups. The control group performed the routine rehabilitation training after the acupuncture, while the treatment group during the acupuncture. The pain and edema of the affected hands were observed. Results The pain and edema decreased significantly after treatment compared with that of control(P<0.01). Conclusion The rehabilitation training during acupuncture is more effective on shoulder-hand syndrome than the routine rehabilitation training after acupuncture.
