Chinese Journal of Pathophysiology 2000;0(11):-
AIM: To investigate the effects of c-fos antisense oligoneuleotide and p21 genetic transfection on the intimal proliferation of venous autografts. METHODS: The external jugule veins were autografted into common carotid arteries in the same side in 20 New Zealand rabbits, which were divided evenly into experimental and control group randomly. The transplanted veins of experimental group were immersed in the adenovirus - mediated p21 gene solution for 15 minutes just before anastomosis and coated with c-fos antisense oligoneucleotide glue gel just after anastomosis, while the control was only treated with empty vector. The transplanted vascular sample were taken at 2 weeks after operation. The intimal thickness (IT), degree of restenosis (DR), expression of proliferating cell nuclear antigen (PCNA), quantity of VSMC were determined by immunohischemistry. RESULTS: The IT , DR and expression of PCNA, VSMC were decreased, compared to control group. CONCLUSION: Transfection of c-fos antisense oligoneuleotide and p21 gene inhibits the intimal proliferation of venous antografs. [
4.Study of procalcitonin and C-reactive protein in predicting enterog-enous bacterial infection among diarrheal patients after irinotecan chemotherapy
Chinese Journal of Clinical Oncology 2015;(7):382-385
Objective:To investigate procalcitonin and C-reactive protein levels in diarrheal patients who underwent irinotecan che-motherapy. Methods:Procalcitonin and C-reactive protein were detected among 85 diarrheal and 63 non-diarrheal patients after irinote-can chemotherapy. Results:According to WHO classification, patients without diarrhea are classified as grade 0, whereas patients with diarrhea can be classified as gradesⅠ-Ⅳ. In grades 0,Ⅰ,Ⅱ,Ⅲ, andⅣpatients, the levels of procalcitonin were 0.29 ± 0.17, 0.30 ± 0.18, 0.36 ± 0.20, 1.24 ± 0.22, and 2.15 ± 0.26 ng/mL on the second day, respectively. However, on the fourth day, the procalcitonin lev-els were 0.28 ± 0.15, 0.30 ± 0.14, 0.34 ± 0.18, 2.00 ± 0.22, and 2.40 ± 0.28 ng/mL, respectively. Moreover, in grades 0,Ⅰ,Ⅱ,Ⅲ, andⅣ, the levels of C-reactive protein were 6.06 ± 1.85, 6.12 ± 1.16, 6.20 ± 1.68, 22.62 ± 4.55, and 31.26 ± 5.23 mg/L on the second day, respectively. On the fourth day, the C-reactive protein levels were 5.80 ± 1.82, 5.94 ± 1.14, 6.15 ± 1.55, 30.52 ± 4.74, and 38.67 ± 5.68 mg/L, respectively. No significant difference was found between the procalcitonin and C-reactive protein levels of stagesⅠandⅡpa-tients (P>0.05), but a significant difference was found between stagesⅠ, andⅡpatients and stagesⅢandⅣpatients (P<0.05). Con-clusion: Monitoring levels of procalcitonin and C-reactive protein may be helpful in the early evaluation of the severity of diarrhea. This process has prognostic effect and can be used to assess whether patients have enterogenous bacterial infection. Monitoring the lev-els of these proteins has certain clinical value and can be used to guide early anti-infection therapy.
5.Rutin inhibits hydrogen peroxide-induced apoptosis through PI3K/AKT signaling pathway in human lens epithelial cells
Acta Universitatis Medicinalis Anhui 2015;(8):1107-1110
Objective To explore whether PI3K/ AKT signaling pathway participates in the inhibiting effect of Ru-tin on H2 O2-induced apoptosis in human lens epithelial cells( HLEC). Methods HLEC were divided into four groups: control group,H2 O2 group,rutin group,LY294002 group. Cell survival rates were determined by a 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay; cell apoptosis rates were monitored by flow cytometry with Annexin V-FITC and propidiun iodide(PI) staining. Western blot was used to measure the expres-sion levels of AKT and p-AKT. Results H2 O2 induced HLEC apoptosis. Compared with H2 O2 group,rutin group not only increased the expression lever of p-AKT,but also reduced cell apoptosis rate(P < 0. 01). In LY294002 group, LY294002, an inhibitor of PI3K/ AKT signaling pathway,could significantly block the change of these inde-xes produced by rutin group(P < 0. 01), but no significant change compared with H2 O2 group. Conclusion Rutin inhibits H2 O2-induced cell apoptosis and may be associated with PI3K/ AKT signaling pathway.

Objective To observe the effects of bulbar subconjunctival and periocular injection of dexamethasonone on blood glucose levels of type 1 diabetic mellitus (T1DM)rats.Methods 80 healthy adult male Sprague-Dawley rats were randomly divided into Group Ⅰ (n-=-40) and Group Ⅱ (n =40).Group Ⅰ rats received intraperitoneal (IP) injection of streptozotocin to induce T1DM model,while Group Ⅱ rats received IP injection of citrate buffer solution and was the control group.Group Ⅰ rats and Group Ⅱ rats were further divided into four subgroups:A (n=10),a (n=10),B (n=10),and b (n=10).Subgroup-A rats received bulbar subconjunctival injection of dexamethasone,subgroup-a rats received bulbar subconjunctival injection of saline,subgroup-B rats received periocular injection of dexamethasone,subgroup-b rats received periocular injection of saline.After the injection,rats were fasted but could drink water.Tail vein blood samples were collected and the blood glucose level was measured by glucose monitor.Results After modeling,the blood glucose level of Group Ⅰ and Group Ⅱ rats was(9.31±1.79) mmol/L and (5.72±0.80) mmol/L respectively,the difference was statistically significant (P<0.05).The blood glucose level of Group Ⅰ rats reached the peak in 3h after injection.In 6-24 h after injection,the blood glucose level of Group Ⅰ A rats was obviously increased than that of the blood glucose level of Group Ⅰa rats and the difference was statistically significant (P<0.05).In 3-24 hours after injection,the blood glucose level of Group Ⅰ B rats was obviously increased than that of the blood glucose level of Group Ⅰ b rats and the difference was statistically significant (P<0.05).Comparing the blood glucose level during different injection time between Group Ⅰ A rats and Group Ⅰ B rats,between Group Ⅰ a rats and Group Ⅰ b rats,the difference was not statistically significant (P>0.05).In 3-24 hours after injection,the blood glucose level of Group Ⅱ A rats was obviously increased than that of the blood glucose level of Group Ⅱ a rats and the difference was statistically significant (P < 0.05);the blood glucose level of Group Ⅱ B rats was obviously increased than that of the blood glucose level of Group Ⅱb rats and the difference was statistically significant (P<0.05).Comparing the blood glucose level during different injection time between Group Ⅱ A rats and Group Ⅱ B rats,between Group Ⅱ a rats and Group Ⅱ b rats,the difference was not statistically significant (P > 0.05).Conclusion Bulbar subconjunctival injection and periocular injection of dexamethasone could both increase the blood glucose of TIDM rats,but these two injection methods had no differences on the blood glucose level.
7.Estimate of the Amount of Blood Loss after Cesarean Section by Different Methods and Analysis the Related Risk Factors of the Blood Loss More than 500 ml
Journal of Practical Obstetrics and Gynecology 2017;33(6):461-464
Objective:To choose a best method of estimating the amount of blood loss after cesarean deliveryby comparing of three methods,to analyze the related factors of the amount of the blood loss more than 500ml after cesarean section.Methods:We collected the clinical data of the patients who were accepted cesarean delivery and treated in our hospital between January 2014 and December 2014.We estimate the amount of blood loss by different methods(including visually estimated,hematocrit (HCT) change and formula).Based on the formula method as the gold standard,we analyze the risk factors of the patients whose blood loss were more than 500 ml.Results:Among the 583 patients,using the method of visually estimated,there were 23 cases whose blood loss were more than 500 ml(3.95%),using the method of formula,there were 133 cases whose blood loss were more than 500 ml (22.81%),using the method of HCT change,there were 116 cases whose blood loss were more than 500 ml(19.90%).The incidence of patients whose blood loss were more than 500 ml between HCT change and formula method showed no significant difference(P > 0.05),but the incidence by visually estimated method was less than the two other methods (P < 0.05).We found the value of HCT change was a statistically significant positive correlation with the amount of blood loss more than 500ml.When the blood loss was more than 500 ml,the accuracy and sensitiveness of HCT method were significantly higher than those of visually estimated method(76.69%,87.93% vs 12.78%,73.91%,respectively).Abnormal labor,uterine leiomyoma,placental factors,and macrosomia were risk factors of cases whose blood loss more than 500ml.Conclusions:HCT method is similar in accessing the blood loss after cesarean section with formula method,especially in the cases whose blood loss was more than 500 ml;HCT method is more convenient than formula method,and more accurate than visually estimated method.HCT method can be used as the standard for estimating blood loss initially,and formula method should be used as the method for estimating the blood loss accurately.Patients with macrosomia and abnormal labor are more likely to occur massive hemorrhage after cesarean section.
