ObjectiveTo describe the use of endoscopic technique for exposure of the mandibular ramus-condyle unit(RCU) to facilitate reduction and rigid fixation of the fractures.MethodsSixteen patients ( 18 sides) with diagnosis of subcondylar fracture ( 11 sides),condylar neck fracture ( 2 sides ),and mandibular ramus fracture (5 sides ),who underwent endoscopic exposure of the RCU and fixation with miniplates by an extraoral or transoral approach.Six sides were no displacement,10 sides were obvious displacement,and 2 sides were dislocation.ResultsAll patients had successful treatment of fractures of the mandibular RCU,all patients showed quick recovery to preinjury occlusion.Followed up 12-36 months,normal temporomandibular joint function was noted in all patients.No patient had marginal mandibular nerve weakness or other complications.ConclusionsIt demonstrates the feasibility of endoscopic access to the RCU for treatment of the fractures.The procedures can be performed with minimal morbidity and functional impairment.

Objective: To examine the effects of berberine on atherosclerosis and plasma levels of lipid in rabbits. Methods: 18 male New Zealand rabbits were randomly divided into 3 groups: control group, untreated cholesterol-fed group, and berberine treated group, which were fed for 12 weeks. After 12 weeks, plasma levels of total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were measured enzymatically by automatic facilities and the aorta was harvested for pathologic morphology observation. Results: The aorta plaque/intima size (P/I) was 0%, (59.6 ± 13.7) % and (36.3 ± 16.5) % in control, untreated cholesterol-fed group and berberine treated group respectively by pathologic morphology observation (P < 0.01). The maximum plaque thickness, the average plaque thickness, the degree of aortic stenosis and the proportion of the intimal circumference occupied by atheroma of 3 groups were different from each other significantly (P < 0.01). Plasma levels of TC and HDLC in berberine treated group were decreased significantly (by 28.88% and 40.94% respectively) compared with that in untreated cholesterol-fed group (P < 0.01). Plasma levels of HDLC and TG in berberine treated group showed no difference from untreated cholesterol fed group (P > 0.05). Conclusion: Berberine can decreased plasma levels of TC and HDL C and suppress the progression of atherosclerosis and stabilize the plaque in experimental atherosclerosis.

Objective To study the effect of medically activated charcoal on serum phosphorus level and calcium-phosphorus products in dialysis patients with poorly controlled hyperphosphatemia. Methods A single-center,prospective,self-controlled study was performed.Medically activated charcoal was administered 4.5-7.2 g per day with meals for three months to hemodialysis or peritoneal dialysis patients with hyperphosphatemia after taking calcium-based phosphate binders.The levels of blood phosphorus,calcium,calcium-phosphorus products,intact parathyroid hormone (iPTH),albumin and hemoglobin were detected before and after the treatment.The results were analyzed using paired t-test. Results After 3 months of treatment,the patients' serum phosphorus level was significantly reduced from (2.16 ±0.34) mmol/L (pretreatment) to (1.85±0.30) mmol/L (post-treatment) (P＜0.01).Similarly,the serum calciumphosphorus products were lowered from pre-treatment level of (63.93 ±8.83) mg2/dl2 to posttreatment of (54.12±8.37) mg2/dl2 (P＜0.01).Serum albumin level was slightly reduced from (41.7±2.9) g/L to (40.1±2.2) g/L (P=0.001).In contrast,there were no significant changes in serum calcium and iPTH levels when compared pre- to post-treatment values (P=0.734 and P=0.665,repectively). Conclusion In combination with calcium-based phosphate binder therapy,oral medically activated charcoal can effectively reduce the levels of blood phosphorus and calciumphosphorus products in dialysis patients with refractory hyperphosphatemia.
