Objective To study the effect of hydroxychloroquine (HCQ) on the suppressors of cytokine signaling (SOCS) in the kidney of MRL/lpr mice and evaluate the protection of HCQ on lupus nephritis.Methods Twenty-six rats were randomly divided into 3 groups:the control group which was consisted of 6 mice; the MRL/lpr group which was consisted of 10 mice; and the HCQ group which was consisted of 10.24-hour urinary protein level and anti dsDNA levels were tested.The expressions of SOCS-1 and SOCS-3 protein were determined by western blot.Analysis of variance was used to determine statistically significant differences between the two groups.A P value less than 0.05 was considered to be statistically significant.Results Compared with the control group,the levels of 24-hour urinary protein [(2 356.6±509.3) mg vs (440.3±90.1)mg] and anti ds-DNA (128.7±32.3 vs 14.9±1.4) were significantly increased in the MRL/lpr group,the expression levels of SOCS-1 and SOCS-3 protein were increased.After treated with HCQ,the levels of 24-hour urinary protein [(70.8±11.1) mg vs (2 356.6±509.3) mg] and anti-dsDNA (111.8±330.1 vs 128.7±32.3)were significantly decreased,the expression level of SOCS-1 and SOCS-3 protein decreased significantly (P＜ 0.05).Conclusion HCQ can inhibit SOCS expression in the kidney of lupus mice,reduce proteinuria and delay progression of immune disorders and lupus nephritis.

OBJECTIVE:To explore the effects of Compound Ligusticum chuanxiong drop pill on hemorheology and blood gas in model rats with diabetic nephropathy(DN). METHODS:60 rats were randomly divided into normal control group,model group, positive control group [Irbesartan tablet,0.013 g/(kg·d)] and Compound L. chuanxiong drop pill high-dose,medium-dose,low-dose groups [0.4,0.2,0.1 g/(kg·d)],10 in each group. Except for normal control group,rats in other groups were given high-sugar high-fat feed and intraperitoneally injected streptozotocin to reduce DN model. After 7 d modeling,rats in each group received relat-ed drugs intragastrically,once a day,10 mL/kg;normal control group and model group received equal volume of purified water in-tragastrically. After 64 d,hemorheology indicators [whole blood viscosity(high-shear,medium-shear and low-shear),plasma viscosi-ty,whole blood reduced viscosity] and blood gas indicators(carbon dioxide partial pressure,oxygen partial pressure,hemoglobin content,oxygen saturation,ratio of oxygenated hemoglobin to total protein) of rats were determined,hematoxylin-eosin staining was used to observe the pathological changes in kidney tissue. RESULTS:Compared with normal control group,hemorheology indi-cators and carbon dioxide partial pressure in model group were significantly increased(P<0.05 or P<0.01),oxygen partial pres-sure,hemoglobin content,oxygen saturation,ratio of oxygenated hemoglobin to total protein were significantly decreased(P<0.05 or P<0.01),with severe kidney damage. Compared with model group,except the improvement of carbon dioxide partial pressure, oxygen partial pressure,hemoglobin content in rats were not significant in Compound L. chuanxiong drop pill low-dose group,the above-mentioned indicators in other medicine groups were significantly improved(P<0.05 or P<0.01);the kidney tissue damage was improved to varying degree. CONCLUSIONS:Compound L. chuanxiong drop pill can significantly improve the hemorheology indicators of DN model rats,reduce blood viscosity,improve microcirculation and capacity of the blood to transport oxygen,and has certain improvement effect on kidney tissue morphology of DN rats.

The present study describes systematically the ultrastructural changes of blood and some organs of rabbits, goats and rats with severe decompression sickness. In our experiment, the animals were exposed to pressure of 0.6 MPa and 1.0 MPa for 60 minutes respectively, to induce severe decompression sickness. The results are as follows: 1. Abnormality of platelets. The granules of platelets decreased and the platelet pseudopods were formed with adhesion and aggregation of platelets. 2. Deformation of erythrocytes. Triangle-like or shell-like cells, dacryocytes, twisted cells, and Ⅰ—Ⅲ type echinocytes were found. 3. Changes of endotheliocytes of the vascular wall became flattened. The space between these cells significantly widened (up to 4-18?m), and blood cells could be found to have wedged into it. 4. Formation of air-blood surface by the intravascular blood. 5. Alteration of organelies. There occured the expansion of rough endoplasmic reticulum, the degranulation and rupture of membranes, as well as the swelling and dissolution of mitochondria.

Objective To determine the change of maternal heart rate during the treatment with ritodrine for threatened premature labor. Methods110 cases of threatened premature labor were chosen. The ritodrine 100mg in 5% G. S 500mL was intravenously administered. The initial dosage was 6 drops/min, and the dose was increased until uterine contractions were inhibited. The treatment lasted for 40 to 48 hours after the uterine contractions were inhibited, then the oral tablets was recommended. If necessary, repeated treatment was given to some patients. The maternal heart rate was recorded in the whole process of treatment and was compared with the dosage administered. The labor time, fetal weight and Apgar′s score were also analyzed. Results The maternal basic heart rate was increased at first and then decreased. The increasing significantly increased( P ＜ 0.01 ) when the uterine contraction was inhibited. , but no difference showed among the groups of different gestational age( P＞0.05 ). The maternal heart rate was increased with the increasing of ritodrine( max. 140/min). labor time was significantly prolonged with the treatment of ritodrine( P＜0.01 ) ,while that of the idiopathic premature labor was prolonged most obviously ( P ＜ 0.05 ). Average fetal weight was (2.42 ± 0.49) kg, and the average Apgar′s score was≥8. Conclusion In the treatment of inhibiting uterine contractions,the increasing of maternal heart rate caused by ritodrine can be used as an indicator of therapeutic effect.
