Objective To establish a rabbit model of hypoglycemia and evaluate the accuracy and timeliness of hypoglycemia monitoring by continuous glucose monitoring system (CGMS).Methods Sixteen female New Zealand white rabbits were randomly divided into 4 groups, with 4 rabbits in each group.The rabbits in the control group were given intravenous infusion of saline.The animals in the experimental group were infused with insulin continuously, which were divided into 0.1 U/kg/h insulin group (RI=0.1 U group), 0.2 U/kg/h insulin (RI=0.2 U group) group and 0.4 U/kg/h insulin group (RI=0.4 U group) accordingly.During the experiment, CGMS was monitored for 240 min.Blood samples were collected at a 30-minute interval and the blood glucose level was measured by a hand glucose meter.Results A total of 1296 CGMS monitoring data were obtained during the study period, and 136 BG monitoring data matched with CGMS time were obtained.After the insulin administration, BG and CGMS were significantly decreased.The reduction rates of BG and CGMS were 0.016 and 0.017 mmol/L/min in the RI=0.1 U insulin group, 0.04 and 0.027 mmol/L/min in the RI=0.2U insulin group, and 0.049 and 0.032 mmol/L/min in the RI=0.4 U group.According to whether BG monitoring value was lower than 4.4 mmol/L, the BG-CGMS paring data were divided into hypoglycemia and normoglycemia.In hypoglycemia, the average deviation of BG-CGMS was 0.55 mmol/L (the upper and lower limits were-0.98 and 2.08 mmol/L, respectively) and the absolute difference percentage (RAD) was 40.2% ± 45.2%.The mean deviation of BG-CGMS in normal blood glucose was-0.19 mmol/L (upper and lower limits were-1.38 and 1.00 mmol/L, respectively) and 5.8% ± 5.3% in RAD.The error grid analysis (EGA) showed that the proportion of zone A was 93.4%, 0.7% in zone B, and 5.9% in zone D, and the zone D was distributed in area of low BG and high CGMS.Conclusions The results of this study indicate that CGMS has a significant hysteresis phenomenon when blood glucose is reduced rapidly.When the blood glucose levels fall below 4.4 mmol/L, CGMS may have a risk of overestimating blood glucose.Such risk should be fully considered during CGMS clinical application.

Objective To explore the clinical efficacy of the combination of the vaginal and high frequency electric wave loop(LEEP) in the treatment of cervical precancerous lesions.Methods The clinical data of 76 cases with cervical precancerous lesions confirmed by postoperative pathological examination were collected,Pathologic biopsy was conducted under colposcope.For patients with operative indication, LEEP operation was carried out under colposcope and analyzed vaginal microscopic pathological biopsy diagnosis accurate rate.The operation time,bleeding volume and treatment were observed.Results Satisfactory colposcopy and biopsy results difference had statistical significance;colposcopy with biopsy diagnosis accurate rate was 90.79%.The average operation time was (6.42±1.21)min.The mean operative bleeding was (10.45±2.31)mL.Postoperative 3 months, TCT negative rate was 95.83%(92/96).After 6 months of TCT negative rate was 100.00%(76/76).Conclusion LEEP combined with vaginal cytology in the treatment of cervical precancerous lesions has less invasion,less bleeding,shorter hospitalization time,and can effectively remove the lesion site,it is worthy of recommending.

Objective To explore the value of laparoscopic assisted vaginal hysterectomy in the treatment of large uterine fibroids.Methods 76 patients with giant hysteromyoma were randomly divided into two groups.38 patients in the control group underwent conventional open surgery, 38 cases in the observation group received laparoscopic assisted vaginal hysterectomy surgical treatment.The operation time, amount of bleeding in operation, postoperative anal exhaust time, get out of bed activity time, length of operation time and the postoperative complications were compared between the two groups.Results In the observation group, the operation bleeding[(65.28±4.86)mL], operation time[(76.29±5.32)min], postoperative anal exhaust time[(10.18±2.01)h], postoperative bed activity time[(14.02±2.18)h] and hospitalization time[(4.05±1.26)days] were significantly better than those of the control group, the differences were statistically significant (t=6.830,8.066,6.598,13.747,6.303,all P<0.05).The incidence rate of postoperative complication of the observation group was 5.26%, which was lower than 15.79% of the control group, the difference was statistically significant (x2=5.887,P<0.05).Conclusion The treatment of giant hysteromyoma patients with laparoscopic assisted vaginal hysterectomy the uterus resection has more advantages than the traditional laparotomy, with less amount of bleeding, fast postoperative recovery and less postoperative complications, it is worthy of recommendation.

Objective To investigate the effects of recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid on neonatal diaper dermatitis. Methods One hundred and twenty neotates with neonatal diaper dermatitis from August 2013 to July 2014 were randomly divided into the control group and experiment group, 60 cases in each group. The control group was treated with conventional care, while the observation group with recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid. The total effective rate and the treatment time were compared between the two groups. Result The total effective rate of the observation group was significantly higher than that of the control group (P<0.05) and the treatment time of the observation group was statistically significantly shorter than that of the control group (P<0.05). Conclusion Recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid is effective in the treatment of neonatal diaper dermatitis and it is worth promoting and using clinically.

OBJECTIVE:To observe clinical efficacy and safety of Ginkgo biloba extract combined with olmesartan me-doxomil in the treatment of essential hypertension,and to discuss its effect on the expression of serum protein. METHODS:98 pa-tients with essential hypertension were selected and randomly divided into observation group A and observation group B,with 49 cases in each group;40 healthy volunteers were included in control group. Observation group A was given Olmesartan medoxomil tablet 20-40 mg,po,qd;observation group B was given Olmesartan medoxomil tablet 20-40 mg,po,qd+ Extract of G. biloba leaves tablet 40-80 mg,po,bid. Treatment course lasted for 4 weeks. Blood pressure(SBP and DBP),TCM symptom score,the repeti-tiveness and resolution ratio of 2-DE spectrum,protein differentiation expression point,related information of differentiation expres-sion protein in 3 groups and ADR of observation group were observed. RESULTS:After treatment,SBP,DBP and TCM symptom score of observation group were significantly lower than before;those indexes after 4 weeks of treatment were significantly lower than those after 2 weeks after treatment;the observation group B was significantly lower than the observation group A,with statisti-cal significance(P<0.05). The repetitiveness and resolution ratio of protein differentiation expression point in observation group B were significantly better than in observation group A after treatment. The expression of 15 protein points in observation group down-regulated before treatment,and up-regulated after treatment to different extents;the observation group B was closer to control group,compared to observation group A. The expression of 6 protein points up-regulated,and then down-regulated to different extent after treatment;the observation group B was closer to control group,compared to observation group A. A total of 11 protein points were identified. There was no statistical significance in the incidence of ADR between observation group A and observation group B (P>0.05). CONCLUSIONS:G. biloba extract combined with olmesartan medoxomil greatly influences the expression of serum pro-tein in patients with essential hypertension and shows good antihypertensive and pressure-control effects with good safety.
