China Pharmacy 1991;0(05):-
OBJECTIVE:To draw a comparison between 6% Hetastarch(H)and Succinylated Gelatin(G)in fluid expansion and their effects on blood coagulation activity.METHODS:A total of 60 surgery patients who needed volume expansion with colloid fluid were randomized to H group and G group.According to the design,the same dose of H and G were infused into the patients.Before and after infusion,the vital signs were monitored and the venous blood samples were taken for the determination of indexes of coagulation,fibrinolysis and electrolyte.RESULTS:There were no significant differences in the vital signs between two groups.After volume expansion,blood platelets counts in two groups were significantly decreased,much as in H group.And the APTT in H group had been significantly prolonged.In group G,only FIB decreased significantly.After volume expansion,free Ca2+ and total Ca2+ were decreased in both groups.Low level of K+ in group G was noted following diluti-on,and Cl-in group H increased significantly.CONCLUSION:Both group showed good volume expansion effects and stable fi-brinolytic function.Hyperchloremia should be alert in group H,and if necessary,Ca2+ should be promptly added in two groups.

Objective To explore the level of serum transforming growth factor-β1 (TGF-β1) in patients with prehypertension and impaired fasting blood glucose.Methods A total of 180 healthy subjects with matched age and sex was divided into 3 groups:group A (blood pressure < 120/80 mmHg and fasting blood glucose <6.1 mmoVL),group B (prehypertension and fasting blood glucose <6.1 mmol/L),group C (prehypertension and 6.1 mmol/L≤ fasting blood glucose ≤7.0 mmol/L).There were 60 subjects in every group.Serum TGF-β1 was measured by Enzyme-Linked Immunosobent Assay (ELISA),fasting blood glucose,triglyceride,total cholesterol,low-density lipoprotein cholesterol ( LDL-C),high-density lipoprotein cholesterol ( HDL-C),Uric Acid ( UA),body mass index (BMI) were determined.Results The level of serum TGF-β1 in group B and C was higher in that in group A( t =2.071,and 2.147,P <0.05 ).The level of serum TGF-β1 was higher in group C than group B,but no significant difference was observed ( P >0.05).The pearson correlation analysis showed there was a significant correlation between TGF-β1 and systolic blood pressure ( r =0.279,P =0.047).Conclusions The level of serum TGF-β1 was higher in patients with prehypertention which may mediate the target organ damage caused by the prehypertention.

Background Epithelial-mesenchymal transition (EMT) is a major event in the pathogenesis of posterior capsular opacification (PCO),and the expressions of α-smooth muscle actin (α-SMA) is the marker of EMT.Previous studies showed that breviscapine plays an important role in anti-fibrosis and suppression EMT,however,the mechanism of its effect on EMT in LECs is unclear.Objective Present study was to investigate the effect of breviscapine on the expression of α-SMA and fibronectin (FN) in human LECs induced by transforming growth factor-β2 (TGF-β2).Methods Human LECs strain,HLE-B3,was cultured and passaged in DMEM containing 10% fetal bovine serum.Different concentrations of breviscapine (6.75,12.75,25.00,50.00 and 100.00 mg/L)were added into the medium for 24,48 and 72 hours respectively,and then cell cunting kit-8 (CCK-8) was used to evaluate the half maximal inhibitory concentration (IC50) of breviscapine to HLE-B3.In addition,HLE-B3 was subcultured at the density of 1 × 106/hole and divided into 4 groups.The cells were in free-serum medium as the normal control;the cells were exposed in 10 μg/L TGF-β2 as TGF-β2 group;while in the breviscapine group,10 mg/L of breviscapine was added into the culture medium and another group was the combination of 10 mg/L breviscapine and 10 μg/L of TGF-β2 treatment.Real-time PCR and Western blot were used to detect the mRNA expressions of α-SMA and FN as well as their protein in HLE-B3 72 hours after cultured.Results The inhibitory rate of breviscapine to HLE-B3 proliferation was gradually elevated with the increase of concentration of breviscapine,showing a significant inhibition of the cell proliferation among the different groups and at various time points (F =292.851,P=0.000;F =65.037,P=0.000).IC50 of HLE-B3 at 72 hours was 22 mg/L,and therefore,in rest of experiment 10 mg/L of breviscapine was used which was 1/2 only half of the IC50.α-SMA and FN were expressed in cultured normal HLE-B3.The expressing level of α-SMA mRNA and FN mRNA in the HLE-B3 was significantly different among the normal group,TGF-β22 group,breviscapine treatment group and combination group as well as at various time points (F =105.490,P =0.000 ; F =1041.414,P =0.000).Similarly,the protein expressions of α-SM A and FN in the HLE-B3 was significantly different among the four groups and different time points (F=136.872,P=0.000;F=119.820,P=0.000).The expression levels of α-SMA and FN mRNA and their proteins in HLE-B3 were remarkably increased in the 10 μg/L TGF-β2 group compared with the normal control group (at all P=0.000),and those in the combination group were obviously declined in comparison to the TGF-β2 group (P =0.001,0.001,0.001,0.010).No significant difference was found in the expressions of α-SMA and FN in the HLE-B3 between the breviscapine group and normal control group in both transcriptional level and protein level (P =0.551,0.292,0.551,0.360).Conclusions 10 mg/L breviscapine can arrest the proliferation and EMT of human LECs.This result suggests that using breviscapine may be a potential prophylactic approach in the prevention of PCO.

?AIM:To evaluate the objective visual quality of patients who underwent corneal cross-linking for the keratoconus using double-pass analysis system.? METHODS: Advanced keratoconus patients who underwent UV - riboflavin corneal cross - linking from January to July 2015 were included. The outcomes of their objective scattering index ( OSI ) , predicted visual acuity ( VA ) , the cut - off frequency of modulation transfer function ( MTF cut- off ) , the Strehl ratio ( SR ) were compared before and 6mo after corneal cross-linking.?RESULTS: A total of 13 patients ( 16 eyes ) were included. There was no statistically significant difference between pre- and 6mo postoperative data in uncorrected visual acuity, best corrected visual acuity, refractions and mean value of Sim-k (P>0. 05). Non-invasive average tear film break up time ( NIAvg-BUT ) detected by the Sirius system decreased after corneal cross-linking ( P<0. 05 ) . Using double - pass analysis system, no statistically significant change was found in MTF cut off, Strehl Ratio, OSI before and after treatment(P>0. 05). Tear Film Analysis Mean OSI increased at 6mo postoperatively (P<0. 05).? CONCLUSION: The subjective visual quality isn’t effected by corneal cross-linking. The tear stabilities of patients are influenced by these operations at 6mo postoperatively. More observations on long-term effect are needed to be taken in the future.
