Objective To evaluate the incidence of hyponatremia in patients with Guillain-Barré syndrom (GBS) and to explore whether hyponatremia is an important predictor of poor outcome.Methods All 455 GBS patients met the inclusion criteria and were divided into three groups as mild,moderate and severe GBS according to Medical Research Council sumscore (MRC sumscore) at nadir.Hyponatremia is defined as serum sodium concentration below 135 mmol/L at nadir.The incidences of hyponatremia in GBS patients with different MRC sumscore were analyzed by x2 tests.Logistic regression models were performed to determine risk factors of hyponatremia and poor prognosis.Results Of all the 455 GBS patients,mild,moderate and severe groups patients were 178,100 and 177 respectively,and 98 (21.5％) GBS patients had hyponatremia.Hyponatremia was more often detected in severe GBS cases (64,36.2％),than in mild (21,11.8％) or moderate (13,13.0％,x2 =28.921,17.074 respectively; all P ＜ 0.01) cases,but there was no significant difference between mild and moderate patients (x2 =0.086 ; P =0.769).Logistic regression analysis identified 3 predictors of hyponatremia:age ＞ 50 (OR =2.013,95％ CI 1.155-3.508,P =0.014),facial weakness (OR =2.493,95％ CI 1.423-4.369,P =0.001) and mechanical ventilation (OR =12.871,95％ CI 5.484-30.207,P =0.001).The presence of hyponatremia (OR =12.770,95％ CI3.419-47.701,P =0.001) and bulbar weakness (OR =3.391,95％ CI 1.182-9.733,P =0.023)predicted death in acute stage.Conclusion As an important predictor of poor outcome in GBS patients,hyponatremia is more likely occurred in patients with older age,facial weakness or respiratory failure.

C. Conclusion Adequate hemodilution can attenuate the lung injury induced by I/R. The protective effect is better if hemodilution is performed before I/R.

BACKGROUND:Adipose-derived stem cel s and bone marrow mesenchymal stem cel s are used widely in cartilage tissue engineering, and there are many similarities in biological characteristics between two kinds of cel s. OBJECTIVE:To compare the chondrogenic potential of bone marrow mesenchymal stem cel s and adipose-derived stem cel s in vitro. METHODS:Adipose-derived stem cel s were isolated from the 3-month-old New Zealand white rabbits’ abdomen. Bilateral femurs of rabbits were obtained, and then the bone marrow mesenchymal stem cel s were separated with the adherence screening method. The growth curve of the passage 3 adipose-derived stem cel s and bone marrow mesenchymal stem cel s were drawn, and the doubling time of two kinds of cel s was compared. Then the passage 3 adipose-derived stem cel s and bone marrow mesenchymal stem cel s were treated with chondrogenic induction. After induced for 14 days, the adipose-derived stem cel s and bone marrow mesenchymal stem cel s were treated with toluidine blue staining and type Ⅱ immunohistochemistry staining respectively. RESULTS AND CONCLUSION:Primary bone marrow mesenchymal stem cel s showed aggregative growth, while the primary adipose-derived stem cel s were in single and scattered growth. The proliferation speed of adipose-derived stem cel s was faster than that of bone marrow mesenchymal stem cel s, while the doubling time of adipose-derived stem cel s was shorter than that of the bone marrow mesenchymal stem cel s. After chondrogenic induction for 14 days, both adipose-derived stem cel s and bone marrow mesenchymal stem cel s could express glycosaminoglycans and type Ⅱcol agen, and the expression level of type Ⅱ col agen in bone marrow mesenchymal stem cel s after chondrogenic induction was higher than that in the adipose-derived stem cel s. The in vitro proliferation of adipose-derived stem cel s and bone marrow mesenchymal stem cel s was rapid and stable, but the proliferative ability of adipose-derived stem cel s was faster than that of bone marrow mesenchymal stem cel s. When cultured in single layer, both adipose-derived stem cel s and bone marrow mesenchymal stem cel s could transform into chondrocytes under certain conditions, but bone marrow mesenchymal stem cel s seemed to be more potential than adipose-derived stem cel s.

Through the consultation of TCM ancient classical theory, the relationship of kidney essence, marrow and brain is analyzed. It is discovered that the degenerative brain diseases, represented by Alzheimer's disease (AD) and Parkinson's disease (PD) share the same etiological basis as "kidney essence deficiency and brain marrow emptiness" and have the mutual pathological outcomes as yang qi declining. The Governor Vessel gathers yang qi of the whole body and maintains the normal functional activity of zangfu organs in the human body through the storage, regulation and invigoration of yang qi. It is viewed that the theory of the Governor Vessel is applied to treat the different degenerative brain diseases, which provides the theoretic support and practice guide for the thought of TCM as the same therapeutic program for the different diseases. As a result, the degenerative brain diseases can be retarded and the approach is provided to the effective prevention and treatment of degenerative diseases in central nerve system:

Objective To investigate the effects of Wuling Powder on insulin resistance of C57BL/6J mice induced by high lipid diet, and discuss the mechanism. Methods C57BL/6J mice were randomly divided into six groups:normal group, model group, rosiglitazone group, Wuling Powder in low, middle, and high dose groups, 10 mice per group. Besides the normal group, other five groups were fed with high fat and sugar diet, with a purpose to establish insulin resistance model. Normal group and model group were given pure water. Rosiglitazone group received a gavage with rosiglitazone of 0.75 mg/kg. Wuling Power low, middle, and high groups received gavage with Wuling Power of 1.23, 3.69, 11.07 g/kg, respectively, the does volume was 0.2 mL/10 g, once a day. The weight and abdominal girth were detected every week. At the end of the sixth week, mice were given 12-hour fasting, and their eyeball were taken for blood. The body weight, length, and fat in abdomen and both kidneys were detected. Paraffin section was made with HE staining. FPG and FINS of each group were detected. ISI and IRI were calculated, and TC and TG were detected. Results Compared with the model group, Wuling Powder can significantly reduce the body weight and abdominal girth of mice (P<0.01, P<0.001), improve liver fatty degeneration, lower the FPG, FINS, TCH, TG, IRI, and increase the ISI in mice (P<0.05, P<0.01). Conclusions Wuling Powder has the effect of preventing insulin resistance of C57BL/6J mice induced by high lipid diet.

Objective To investigate the expression of 4-hydroxynonenal (4-HNE) in the kidney of diabetic rats and the effect of probucol.Methods The rats were being intraperitoneal injected with STZ (60 mg/kg) to establish diabetic models.Then diabetic rats were randomly divided into diabetic group (group D,n =24),probucol treated group (group P,n =24).Normal rats were taken as control group (group C,n =24).Rats in group P were treated by probucol (110 mg·kg-1·d-1); rats in group D and group C were given equal volume water instead.Scr,BUN,triglyceride (TG),total cholesterol (TC) and 24-hour urinary proteinin were measured at the 4th,8th and 12th week.PAS staining and HE staining were used to evaluate the pathological changes of the kidney.The immunohistochemistry and Western blotting were used to detect the expression of 4-HNE in renal tissue.Results Levels of Scr,BUN,TG,TC and 24-hour urinary protein in group D were higher than those in group C at the 4th,8th and 12th week(all P ＜ 0.05); Levels of Scr,BUN,TG,TC and 24-huor urinary protein in group P were lower than those in group D at 4th,8th and 12th week (all P ＜ 0.05).The pathological changes of the kidney in group D were more serious than that in group P.The expression of 4-HNE in group D were higher than group C at the 4th,8th and 12th week (all P ＜ 0.05);The expression of 4-HNE in the kidneys of group P decreased significantly compared to that of group D at the same time (P ＜ 0.05).Conclusions As an indicator of lipid peroxidation,the expression of 4-HNE significantly increases in the kidney of diabetic rat.Probucol may protect the diabetic kidney through decreasing the expression of 4-HNE and the level of lipid peroxidation.
