Iatrogenic bile duct injury (IBDI) is a severe complication in general surgery, especially during laparos-eopic cholecystectomy. Many factors may cause IBDi, in which the conscientiousness, skill and experience of the surgeons play a more important role than the abnormal anatomy and patholo-gical changes of the patient. The Bismuth's classification, which originated from the era of open surgery, does not cover the whole spectrum of bile duct injuries. Strasberg's classification made a supplement by including other types of extrahepatie bile duct injuries. The variation of opportunities leads to different thera-peutic strategies. When the injuries are diagnosed intraopera-tively, a conversion to open surgery is the option of choice, and the prosthesis should be performed by a more experienced surgeon. If the bile duct injury is diagnosed in the early stage after operation, therapeutic principles are as follows: biliary peritonitis often required an emergency reoperation, while extra-peritoneal drainage is taken for patients with simple biliary leak. The most serious postoperative complication after IBDI is steno-sis, sometimes followed by fistula. Sufficient preoperative prepa-ration is essential, which includes controlling the biliary tract infection, improving the liver and renal function and nutritional state of the patient.

Objectives:To study the effect of triptolide(Tri) on fibroblast cells in vitro culture, morphologically and kinetically. Methods:Light microscope(LM)and electron microscope(EM)were employed to detect the morphological changes in Tri group. Cell DNA content and apoptosis were assayed by flow cytometry (FCM). Results:In Tri group, fibroblast cells showed less density, slimmer body, abnormally and typical apoptosis under LM, while rarefaction and content of rough endoplasmic reticulum(RER) decrease, and apoptosis in different stages could be seen under EM. In FCM,AI elevated remarkably in Tri groups, and the effect is dose dependent, with cell cycle uninfluenced at all. Conclusions:The mechanism of triptolide on hypertrophic scars is related to its promotion on fibroblast apoptosis and inhibition of collagen excretion.

Excellent teaching team is basic guarantee of top-quality course construction. In order to improve the teaching team construction in dermatology,a lot of work has been done on the team construction,professional degree of medicine,quality construction,etc. As a results,the quality of dermatology teaching team has been greatly improved in the Department of Dermatology of West China Hospital,Sichuan University,which is the basis for the following top-quality course construction.

The patient complained of finding on the right side of the neck fistula with discharge nine years. In recently, fistula spills significantly increased compared with the previous. Special physical examination: Right sternocleidomastoid middle 1/3 front border is seen here in a small fistula, translucence jelly secretion were spilling out when squeezeing the fistula, no smell. Ultrasound: On the right side of the upper cervical skin to submandibular gland rear could see tubular low echo area. MRI: Visible on the right side of the neck tube signal, after the submandibular gland rear. Three-dimensional CT: Visible on the right side of the neck by skin sinus crossings as deep as the tonsillar fossa lumen containing contrast agent. Clinical diagnosis: The second branchial cleft cyst and fistula.

Objective To observe the morphological features of the incisive canal in normal anatomy and abnormalities with multi-slice spiral CT (MSCT). Methods MSCT findings of 108 normal subjects and 65 patients with abnormalities involving incisive canal were retrospectively analyzed. Results The normal incisive canal were classified into 3 types according to the morphology of the nasal opening:two openings, short bony crest and one opening (37.04%, 33.33% and 29.63%, respectively), as well as cylinder, Y-shaped and pyramidal (59.26%, 37.04% and 3.70%) in coronal images, and cylinder, pyramidal and fusiform (84.26%, 14.81% and 0.93%) in sagittal images. The maximum diameter of the nasal and palatal opening was (4.67±1.31) mm and (3.51±0.88) mm (P<0.05). The length of the incisive canal was (10.71±1.95) mm, (11.51±1.97) mm in male and (9.91±1.58) mm in female respectively, and gender difference was found (P<0.05). The angle between the posterior wall and the hard palate was (118.51±9.44)°. The upper and lower length from the anterior wall of the incisive canal to the cortical palate was (9.29±1.26) mm and (7.12±1.21) mm, respectively (P<0.05). The manifestations of abnormalities involving incisive canal including enlargement (47.69%), narrowing (46.15%), shortening (3.08%) and interruption (3.08%) were observed. Conclusion The morphology of the incisive canal can be clearly delineated with MSCT and post processing techniques. It is extremely valuable for avoiding potential complications during surgical procedures such as implant placement and helpful to the diagnosis and treatment of abnormalities involving maxillary incisive canal.

In order to explore more reasonable and scientific accounting method of community health service costs, to improve the accounting method system of community health service cost. In the current existing community health services costing methods, based on the analysis of hospital cost accounting methods system, analyze and imitate the accounting method of hospital costs, establish a more scientific and implemented accounting method system of community health service costs: divide parts of clinics scientifically, redesign the center acollation method of indirect cost, confirm different cost accounting methods for different cost accounting objective and provide suggestion for the improvement of project cost accounting.

Objective To study the MRI features of nasopharyngeal carcinoma (NPC) in patients who presented with ocular abnormalities. Methods The clinical signs and MRI features of Ⅲ, Ⅳ and/or Ⅵ cranial nerve involvement in 22 cases of histologically proved nasopharyngeal carcinoma were retrospectively analyzed. Results All 22 cases showed perineural tumor spread along the course of Ⅲ, Ⅳ and Ⅵ cranial nerve. Diplopia was the most common sign, occurred in 14/22 patients. The incidence of incomplete palsy of Ⅲ, Ⅳ and Ⅵ cranial nerve were 16/44, 7/44 and 4/44, respectively. There were four types of abnormal MRI findings: cavernous sinus thickening (10/44) and mass ( 16/44), superior orbital fissure enlargement (4/44) and abnormal signals (9/44), thickened oculomotor muscles with obscured adjacent fatty space and abnormal enhancement (10/44). The dynamic contrast enhancement patterns of the masses in cavernous sinus and orbital were the same as that of nasopharynx lesions; all appeared as rapid initial enhancement followed by a plateau phase. Conclusion Oculomotor nerve involvement can be the first clinical signs of NPC, and MRI can show the perineural extension along the Ⅲ, Ⅳ and Ⅵ cranial nerve in NPC.

Recombinant PCR applies to fulfill gene recombination by PCR thermal reaction.Over the twenty years,it has branched into three characteristic strategies:splicing by overlapping extension(SOE),jumping polymerase chain reaction(JPCR)and DNA shuffling.Recently,the technique aimed with exploiting natural source of different allele genes is developing up on simplification of experimental procedure,on trap for mutation and variation,and on highthroughput screening with technology of surface display and fluorescent probe.The recombinant PCR is increasesing value in broad range from biological basic research to bioengineering study.
