Objective To explore the effect of atorvastatin on high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) in unstable angina pectoris (UAP) patients after intervention.Methods Eighty cases with UAP who underwent percutaneous coronary intervention (PCI) were divided into group A and group B by random digits table method with 40 cases each after PCI.The patients in group A were given regular heart treatment and atorvastatin 20 mg treatment.The patients in group B were given regular heart treatment and atorvastatin 40 mg treatment.The serum hs-CRP and IL-6 was determined before treatment and 24 h,3 weeks after treatment and compared between two groups.Results There was no significant difference in the serum hs-CRP and IL-6 before treatment between group A and group B [(5.6 ± 1.2) mg/L vs.(5.6 ± 1.1) mg/L and (211.9 ± 21.2) ng/L vs.(209.6 ± 19.9) ng/L,P ＞ 0.05].The serum hs-CRP and IL-6 24 h after treatment in group A and group B were increased compared with that before treatment,and there was significant difference(P ＜ 0.05),but there was no significant difference between group A and group B[(8.1 ± 1.1) mg/L vs.(8.5 ± 1.2) mg/L and (311.1 ± 20.9) ng/L vs.(313.3 ± 18.5) ng/L,P＞ 0.05].The serum hs-CRP and IL-6 3 weeks after treatment in group A and group B were decreased compared with that before treatment,there were significant difference (P ＜ 0.05),and there were significant difference between group A and group B [(3.1 ± 1.1) mg/L vs.(1.9 ±0.8) mg/L and (163.3± 18.5) ng/L vs.(123.3± 19.5)ng/L,P ＜ 0.05].No obvious adverse reaction was observed in two groups after treatment and liver function was not seen obvious anomaly.Conclusions Atorvastatin treatment in UAP patients after PCI can significantly reduce the serum hs-CRP and IL-6,and the 40 mg treatment is better than the 20 mg treatment.It is worth of clinical application.

Objective To investigate the pathological and electro-physiological process of terminal sprouting after muscle injection of Botulinum toxin type A(BTXA) in rats. Methods Sprague-Dawley rats were randomly divided into a BTXA group and a control group. Five unit of BTXA was injected into the right gastrocnemius of the rats in BTXA group, instead of 0.9% saline in the control group. The morphologic axon analysis and SFEMG (mean consecutive difference and fiber density) were measured at 1,4,8,12 week after injection. Results The mean consecutive difference was prolonged in 1-4 week, and got better at 8 week, recovered at 12 week. It was revealed of the recovery of neuromuscular junction at 12 week after BTXA injection. The results of fiber density and morphologic axon analysis demonstrated terminal sprouting after injection of BTXA. Conclusion Motor nerve terminal sprouting could appear after BTXA injection and the function of neuromuscular junction could become recovered at 12 week.

Objective To discuss wound edge characteristics at different clinical periods and in-tervention of traumatic perforation of tympanic membrane. Methods A total of 494 patients wth trau-matic perforation of tympanic membrane were treated and grouped based on treatment time and size of per-foration. Group A (n = 154, within 12 hours after injury) were treated by residual tympanic membrane repair and gelfoam. Group B (n =149, 12 hours after injury) were treated by simple gelfoam. Group C (n = 116) and Group D (n =75) were treated by conventional therapy. The wound healing of peroration was observed after one month. Results Of all, there were 419 patients with maximum perforation diameter > 2.5 mm within five hours after injury, of which 349 patients (83.3%) were with residual tympanic membrane valgus of perforation rim, 29 (6.9%) with involution of perforation rim and 41 (9.8%) with complete loss of tympanic membrane. Of 75 patients with maximum perforation diameter <2.5 ram, residual valgus of perforation rim was found in 18 (24.0%) and tympanic membrane wrinkle near wound edge in the other patients. Under endoscopic repair of crimp tympanic membrane, maximum perforation diameter was reduced for (6.5±2.5)mm in 143 patients at 6th hour, (6.0±1.5)mm in 11at 7-11 hours, (2.0±1.5) mm in 27 at 13-24 hours, (1.5±1.0) mm in 59 at 25.5-48 hours, (1.0±0.5) mm in 49 at 51-73 hours and 0 mm in 14 at 75-192 hours. The follow up lasted for one month, which showed that healing rate of perforation in groups A, B, C and D were 85.3%, 71.2%, 59.2% and 81.4%, respectively. Healing time span was (10±4) days, (19±4) days, (25±2) days and (16±2) days, respectively. Conclusions Traumatic perforation of tympanic membrane is not com-plete tympanal deletion but residual tympanic membrane valgus of perforation rim,involution and tympanicmembrane crushing, which shows insignificant change with time. In time repair of residual tympanic membrane 12 hours(especially 6 hours) after injury may reduce the largest diameter of perforation and re-markably shorten the healing time of perforation.

OBJECTIVE: Evaluation of different repair mechanism and influencing factors for Prognosis of tympanic membrane perforations. METHOD: One hundred and twelve female patients of tympanic membrane perforations were randomly divided into two groups: control group (natural repair group) and treatment group (gelatin sponge patch bonded repair group). The perforation healing were dynamically observed in two groups by endoscope. RESULT: The result show that low, medium and high perforations healing rates were 100.00%, 90.48%, 93.33%. The healing time of low, medium and high was (9.0 +/- 2.8) d, (13.0 +/- 2.6) d, (22.0 +/- 4.7) d, the epithelial layer reverse growth in 5 cases. The result show that low, medium and high perforations healing rates were 91.67%, 95.24%, 84.62%. The healing time of low, medium and high was (11.0 +/- 3.7) d, (24.0 +/- 3.8) d, (36.0 +/- 2.1) d, 2 cases were undergone surgeries. CONCLUSION There are differences in repair mechanism between natural repair and patch bonded repair patch bonded repair can promote granulation hyperplasia, it can help recovering and lessening the patient's conductive hearing loss and occasional tinnitus. granulation hyperplasia and the healing time is closely related. The epithelial layer reverse growth may affect the healing of tympanic membrane perforation.
