Objective To evaluate the repot of common hepatic duct defect caused by Type Ⅱ or Type Ⅲ Mirizzi syndrome laparoscopically.Methods Eight cases of Type Ⅱ or Type Ⅲ Mirizzi syndrome treated under laparoscopy were analyzed retrospectively.Among them six cases were identified as Mirizzi Ⅱ and a defect on the lateral wall of common hepatic duct was found and repmred by suturing the stubble of cystic duct.The two Mirizzi Ⅲ cases had a defect on front and lateral wall or back and lateral wall of common hepatic duct respectively.Both defects were repaired by a patch from the infundibulum of galllbladder. Results All the 8 cases underwent laparoscopic subtotal cholecystectomy followed by repair of common hepatic duct defect.The operation lasted for 80～150 min(mean 110 min).There was no recurrence of the symptoms after 6～24 months follow up.Conclusion The familiarity of the anatomical characters of Mirizzi syndrome and the skillful suture technique under laparoscopy are both necessary.

Objective To investigate the regulation expression of leukemia inhibitory factor(LIF)in hu- man and animal osteoarthritic(OA)tissues and its clinical relevance.Methods 1)Thirty-five Japanese rabbits, aged eight months,were used to make models of experimental osteoarthritis.Operations were performed at the right knee and the sham ones at the left knee in each rabbit.Rabbits were sacrificed on the 3,7,14,28,42,56 and 84 days after operation respectively.Cartilage and synovium of the knee were collected to observe histological changes of osteoarthritis at different times;immunohistochemistry analysis was conducted to observe the LIF expression and distribution in the cartilage and synovium of the animals.2)From April 2003 to October 2003,32 samples of human articular tissues(cartilage,subchondral bone and synovium)were obtained in the operational procedures and a good quantity of RNA was isolated using Magnetic Beads.The patients who underwent articular operations donated the samples.In the reverse transcription-polymerase chain reaction(RT-PCR),the mRNA expression of LIF was mea- sured by semi-quantity analysis and the location of LIF protein was determined by enzyme-linked immunosorbent assay (ELISA).Results A slight expression of LIF was seen in normal cartilage but less in synovium.However,the expression of LIF was remarkable in synovial lining cells,superficial and middle layers of cartilage in animal os- teoarthritis.There was a significant difference in expression between the animal osteoarthritis and the control group (P＜0.05 ).In human tissue study,LIF mRNA was expressed to a very low level in normal articular tissues and there was no significant difference(P＞0.05)between different anatomical locations.In moderate degrading sub- chondral bone,LIF mRNA was expressed to its highest level.LIF was expressed to the highest level in seriously degrading cartilage tissues.The results were similar to ELISA testing results.LIF extents varied in different articular tissue sections.Conclusions LIF is an important mediator that can contribute to tbe pathogenesis of OA.The different temporal and spatial distributions of LIF in normal and OA tissues imply that LIF may play some important roles in pathogenesis of OA.

Objective To explore the clinical effects of aminophylline on bronchiolitis in children.Methods One hundred and twen-ty-eight children with bronchiolitis in our hospital were randomly divided into the experiment and treated control group,in the meantime,and divided into the severe and mild group according to their condition.The children in control group were treated with traditional methods,in experiment group were treated with aminophylline(2 mg/kg,every day one time),as well as used traditional methods.All patients in 2 groups were checked by volume (VT), inhale time and exhale time ratio (Ti/tE),time to peak expiratory flow and expiratory time ratio(tPTEF/Te),time to peak expiratory flow to total expiratory time and volume ratio(vPTEF/vE) respectively. Meanwhile pulmonary function,alkyla-denine glycosylase in trachea secretion,IL-8,cytotaxonomy in trachea secretion on time,after the third day and the 7th day.Their curative effects were evaluated.All parameters were analyzed by statistical methods.Results Cytotaxonomy of the patients in the experiment were more improved than that of control group(P
