Objective To determine the main predictors of circulatory crisis after replantation in patients with severed distal finger so as to establish the theoretic basis in reducing the morbidity of circulatory crisis. Methods 65 severed distal fingers underwent replantation were respectively reviewed. All the clinical parameters including age, sex, dominant hand or finger, preservation of the severed finger, platelet level, ischemia duration, cause of injury, manner of venous drainage, repair of artery, order of reparation and plane of division were investigated as predictive risk factors for circulatory crisis of finger after replantation. In order to find the risk factors of circulatory crisis, the data was dealt with t test, ?2 test, analysis for variance or multivariate Logistic regression analysis. Results 13 replanted finger suffered from impaired circulation in 65 fingers. Univariate analysis demonstrated that many factors were significantly correlated with the circulatory crisis of finger, such as the manner of venous drainage(?2=6.714,P=0.035), the cause of injury (?2=9.049,P=0.011), the preservation of severed finger(?2=6.452,P=0.040), the age(?2=14.838,P=0.001), the platelet level(uc= 2.961, P=0.003). The multivariate Logistic regression analyses showed that platelet level (OR=1.015, P=0.030), the age(OR=0.349, P=0.031) and the manner of venous drainage(OR=0.278,P=0.036) were the significant independent predictors for circulatory crisis. The incidence of circulatory crisis in patients less than 6 years old was 61.5%, significantly higher than any other age group(P

Aim To study the inhibitory effect of anti-ErbB2 chimeric antibody chA21 on proliferation of human malignant breast cancer cell lines SKBR3 and explore its possible mechanisms through studying its effects on ErbB2 distribution and PI3K/Akt,Erk1/2 signal transduction.Methods The inhibitory effect of chA21 on SKBR3 was assessed by MTT assay.The effect of chA21 on distribution of ErbB2 on cell plasma membrane was determined by FACS(Fluorescence-activated cell sorting)analysis;p-Akt and p-Erk1/2 were detected by Western blot.Results The inhibitory rate of chA21 on SKBR3 cells in vitro increased in a dose and time dependent manner.Furthermore,it could down-regulate the distribution of ErbB2 on plasma membrane and decrease the activation of p-Akt and p-Erk1/2.Conclusions ChA21 can inhibit the proliferation of SKBR3 cell in vitro.Down-regulation ErbB2 on cell plasma membrane resulting in decreasing the activation of p-Akt and p-Erk1/2 may be one of the mechanisms of the inhibitory effect.

OBJECTIVETo observe the therapeutic effect of a drug pair of Radix Astragali and Rehmanniae Radix combined with glucocorticoid (GC) in treating lupus nephritis (LN) patients and its influence on some experimental indices.

METHODSTotally 52 LN patients were randomly assigned to the treatment group (treated by routine Western medicine and a drug pair of Radix Astragali and Rehmanniae Radix, 25 cases) and the control group (treated by Western medicine, mainly by GC and cyclophosphamide, 27 cases). All patients received 6-month therapy. The GC dosage, the withdrawal and reduction dosage of GC, clinical efficacy, systemic lupus erythematosus disease activity index (SLEDAI) score, adverse reactions, and laboratory indicators were recorded.

RESULTS(1) All patients got relieved to some degree with the dosage of GC reduced. The total withdrawal and reduction dosage of GC was slightly higher in the treatment group than in the control group [(50.23 +/- 12.43) mg vs (48.76 +/- 13.61) mg, P > 0.05]. Besides, the prednisone dosage in the treatment group was lower than that in the control group, but without statistical difference (P > 0.05). The ratio of patients in need of adding prednisone for aggravating disease was 24.0%, significantly lower than that in the control group (44.44%, P < 0.05). (2) There was no statistical difference in the SLEDAI score, inflammatory indicators, liver and renal functions, blood electrolytes, blood glucose, blood and urine routines between the two groups (P > 0.05). The 24-h urinary protein count was (1.06 +/- 0.22) g/L in the treatment group, obviously lower than that in the control group (1.43 +/- 0.55 g/L, P < 0.05). (3) There was no statistical difference in the incidence rate of infection, gastrointestinal hemorrhage, psychoneuroses, Cushing's syndrome, cardiovascular anomalies, and femoral head necrosis between the two groups (P > 0.05). But the incidence of adverse reactions such as insomnia, tidal fever, spontaneous sweat, and obesity was less in the treatment group than in the control group (P < 0.05).

CONCLUSIONSUsing a drug pair of Radix Astragali and Rehmanniae Radix combined with GC in treating LN could withdraw the dosage of GC and relieve symptoms it induced. It was advantageous in reducing the dosage of GC and stabilizing patients' conditions.

Objective To observe the hemostatic effect of emergent hemostasis patch (EHP). Methods The coagulation time was studied with tube method in vitro. Hemostasis was studied with femoral artery hemorrhage models of rats and dogs as well as rabbit hepatorrhexis model in vivo. Results The clotting time of EHP of high, medium and low concentrations was (4.9±1.3)min, (5.7±1.8)min and (5.8±1.3)min, respectively, which was significantly lower than that of control (14.4±1.6)min in vitro. In femoral hemorrhage models of rats and dogs, the duration and amount of bleeding in EHP of high, medium and low doses were significantly decreased compared with those in the PVF sponge group (P<0.01 or P<0.05). The results of rabbit hepatorrhexis experiment showed that EHP of three doses obviously decreased the hemostatic time and blood loss compared with PVF sponge group (P<0.01). Conclusion EHP can shorten coagulation time and bleeding time, and reduce bleeding amount.

Objective　To study the correlation between the rabbit glucocorticoid receptor(GR) and steroid-induced glaucoma(SIG).Methods　The GR binding in peripheral blood leukocytes and plasma cortisol were measured in 15 adults pigmented rabbits on the first day of experiment, 0.5mg dexamethasone was injected in the right eyes of each rabbit once every 2 days, totally 15 times for 30 days. Right eyes intraocular pressure(IOP) and aqueous outflow facility were measured every week, the relation between GR, plasma cortisol, IOP and aqueous outflow facility(C) was analyzed. Results　After the experiment the IOP increased by 0.67kPa±0.49kPa(P＜0.01),C decreased by 0.08±0.11(P＜0.01).GR may closely be related to IOP and C(r=0.56,P＜0.025; r=0.60,P＜0.01).Plasma cortisol was independent of IOP and C(r=0.27, P＞0.05;r=0.34,P＞0.05).Conclusion　The level of GR has positive correlation with the sensitivity of tissue of eye to glucocorticoid.
