A case of several ambushed bicuspoid supernumerary teeth in the premolar area was reported.The size,shape and the ratio of crown to root of the supernumerary teeth are similar to those of the premolar.The abnormity of tooth germ division and proliferation may lead the supernumerary teeth.

Objective To observe the efficacy of Yinxieling Tablets(YT) for the treatment of psoriasis vulgaris(PV),and to explore its therapeutic mechanism.Methods Forty-eight PV patients were equally randomized into two groups.The two groups received external application of Fubirun ointment.Additionally,the treatment group received oral use of YT(mainly composed of Radix Rehmanniae,Radix Angelicae Sinensis,Radix Paeoniae Rubra,Rhizoma Chuanxiong,Radix Arnebiae seu Lithospermi,Rhizoma Curcumae,Herba Chloranthi Spicati,Rhizoma Smilacis Glabrae,Fructus Mume,Radix Glycyrrhizae,etc.),and the control group received oral use of Acitretin Capsules.Four weeks constituted one treatment course,and the treatment in both groups lasted 2 courses.After treatment,the relief of symptoms and signs in both groups was evaluated by Psoriasis Area and Severity Index(PASI) scoring,the side effects were monitored,and serum interferon-gamma(IFN-?)level was measured.Results(1) At the end of the first treatment course,the therapeutic effect in the treatment group was better than that in the control group(P0.05).(2) After one treatment course,serum IFN-? level was decreased in both groups(P0.05).(3) The adverse effects of dry skin,abdominal discomfort,dry lips and abnormal hepatic and renal function were not obvious in the treatment group(P

The hemorrhage during laparoscopic cholecystectomy (LC) in operating field is a significant puzzle worries the surgeon. Besides disrupting the cystic artery hemorrhage originating from the gallbladder bed also plays a frequent role in the cause of bleeding in LC. The gallbladder bed bleeding which results from the disrupt of the branches of the middle hepatic vein is a ticklish problem in the operation. It will complicate the surgical operation, confuse the anatomic structttre, cause serious complications and is a main reason for conversion. Thus, we compose this review to expound the topographic anatomy of the branches of the middle hepatic vein as well as the prevention and treatment to the injure of the branches of the middle hepatic vein.

History of abdominal surgery was the contradiction of reoperation with laparoscopy. With the development of laparoscopic technique, this contradiction now has been challenged and reoperative minimally invisave surgery is growing. The objective of this article is to state the applications of laparoscopic technique in gastrointestinal reoperative surgery.

Cholesterol polyposis of the gallbladder is a metabolic disorder of cholesterol and characterized by the deposit of cholesterol esters and other lipids in the lamina propria of gallbladder.The pathogenesis is complicated which may involve various factors,and probably associated with the alteration of polygene expression,but at this moment the true nosogenesis is still unclear.

Objective To determine whether the pressure of continuous CO 2 pheumoperitoneum (CCP) affects port site implantation of tumor cells.Methods Male SD rats were injected intraperitoneally with gastric cancer cells (cell line SGC 7901). Continuous CO 2 pneumoperitoneum at 15*!mm*!Hg or 30*!mm*!Hg for 5*!mins,60*!mins,120*!mins and 180*!mins with different number of tumor cell injection(10 4/ml, 10 6/ml respectively) was then established. Several samples of peritoneal washing served as positive control.All collecting dishes were incubated at 37℃ for one week.Results Dishes were tumor cell positive on which the tumor cells were collected from rats undergoing continuous flows of CO 2 gas (5*!L/min) at pneumoperitoneum of 30*!mm*!Hg for 60 mins or longer and all peritoneal washing samples showed tumor growth also. Conclusion It suggests that the number of tumor cells, pneumoperitoneum pressure and the duration may affect the port site implantation.

Objectives To analyze the various protein components in urine and to define the types of proteinuria. Methods Sodium dodecyl sulfate argarose gel electrophoresis was used to analyze 86 non concentrated urine samples from patients with various renal injury. Results According to the images of urine protein electrophoresis, proteinuria can be classified into five types: glomerular, tubular, mixed, over flow, and physiological. Results from 16 cases of renal biopsy showed glomerular type, in 12 cases mixed type in 3, physiological type in 1. Conclusion This method is highly sensitive, simple, less time consuming and easy for long term preservation of results.

Objective To discuss the surgical technique in correction of tetralogy of Fallot with complete atrioventricular septal defect (TOF-AVSD). Methods 16 patients aged 2-16 years underwent correction of TOF-AVSD. The atrioventricular septal defect was closed through a right atriotomy and longitudinal right ventriculotomy in each case. The three-patch technique was used for the first 7 cases and two-patch technique for the later 9 cases. The commissure between the superior and inferior bridging leaflets of the left portion of the common atrioventricular valve was closed in each patient. RVOT obstruction was relieved by a transannular patch. Results Results There were 4 deaths in the early postoperative period, 3 deaths in the first 7 cases compared to 1 death in the later 9 cases (P
