Objective To evaluate the technique of treating severe tuberculous peritonitis complicated with intestinal obstruction. Method Clinical data covering 44 cases from Jan. 1994 to Dec. 2004 were analyzed retrospectively. All the 44 cases were suffering from severe tuberculous peritonitis complicated with intestinal obstruction for a long time. Among them 36 cases were diagnosed pre-operatively and 8 cases were confirmed post-operatively. All the patients underwent laparotomy, and all intestinal adhesions were divided, then the intestine loops were regularly aligned. Result 43 cases were cured, 2 patients developed postoperative intestinal fistula, and one patient died. Conclusion No curative effect could be obtained if medical treatment only was given for tuberculous peritonitis complicated with complete intestinal obstruction. The present surgical technique offers a better chance to relieve intestinal obstruction as a reult of tuberculous peritonitis.

AIM To investigate the effects of iptakalim hydrochloride(Ipt) on the association and dissociation kinetic processes of [ 3H]glibenclamide(Gli) binding with sulfonylurea receptor(SUR 2B ) of ATP sensitive potassium channel (K ATP ) in vascular smooth muscles derived from Wistar rats,and to compare the properties of Ipt with those of nucleotides. The interactions between Ipt and nucleotides were also determined. METHODS The experiments of the association and dissociation kinetic processes of K ATP blocker[ 3H]Gli binding with endothelium denuded aorta smooth muscles were used. RESRLTS (1)The specific bindings of[ 3H]Gli with SUR 2B were not displaced by Ipt at the concentrations of 10 pmol?L -1 ～ 0 5 mmol?L 1 . Ipt 100 ?mol?L -1 retarded the association kinetic process and accelerated the dissociation kinetic process of [ 3H]Gli binding with SUR 2B . (2)Opposite to Ipt, ATP 1 mmol?L -1 accelerated the association kinetic process and retarded the dissociation kinetic process of [ 3H]Gli binding with SUR 2B There was an interaction between ATP and Ipt in the modulation of [ 3H]Gli binding with SUR 2B . (3) Similar with Ipt, ADP 1 mmol?L -1 retarded the association kinetic process and accelerated the dissociation kinetic process of [ 3H]Gli binding with SUR 2B , there was an interaction between ADP and Ipt in the modulation of [ 3H]Gli binding with SUR 2B . (4)Different from ATP and ADP, UDP had no effect on the association and dissociation kinetic process of [ 3H]Gli binding with SUR 2B . And there was not interaction between UDP and Ipt. CONCLUSION Ipt had no affinity with the binding sites of K ATP blocker in SUR 2B , but had negative allosterical modulation on it. The modulatory properties of Ipt were opposite to those of ATP, similar with those of ADP and different from those of UDP. There were interactions between ATP, ADP and Ipt in the modulation of [ 3H]Gli binding with SUR 2B , but there was not interaction between UDP and Ipt.

Objective To investigate the phenotypes and expression of activated T-cell membrane molecules on lymphocytes in the peripheral blood(PB) of children with aplastic anemia (AA) and find out its clinical significance.Methods The lymphocytes from PB of the 115 AA patients were analyzed by flow cytometry and compared with normal group.Results The expression of CD8+ increased and the expression of CD4+ decreased. The ratio of CD4/CD8 cells decreased ,and was more significant in the patients with serious AA(SAA). The expression of HLA-DR and ??T-cell also increased, and was more significant in SAA patients. The expression of CD3+ was not significantly changed.Conclusions There is significant immune abnormal in AA patients and more important in SAA patients. The immunosuppressant is useful in clinical treatment.

Objective:To summarize our experience in perioperative anesthetic management for fulminant hepatic failure (FHF)patients receiving liver transplantation.Methods:The clinical anesthetic data of 48 FHF patients receiving orthotopic liver transplantations(OLT)from January 2006 to January 2007 were retrospectively analyzed,and the anesthetic management expe- rience was summarized.General anesthesia was applied;the hemodynamics was monitored during the operation and doses of adrenaline and phenylephrine were adjusted according to the monitoring results.Blood samples were obtained before operation, before anheptic,30 min after anhepatic phase,5 min before neohepatic phase,and 5 min,30 min and 60 min after neohepatic phase for blood gas and electrolyte analysis and for determination of coagulation function;the drugs were subsequently adjusted according to analysis results.Results:All the 48 patient underwent successful anesthetic management and there was no death dur- ing opearation.The average blood loss during operation was(5 219?478)ml.Mild alkalosis,hypokalemia,hyponatrium,and hy- pocalcemia were present before operations,pH,BE and HCO_3~- were obviously reduced 30 min after anhepatic phase and in- creased 60 min after neohepatic phase.Kalemia was obviously increased 30 min following anhepatic phase and began to increase 60 min following neohepatic phase.Calium concentration was decreased at the end of preanhepatic phase(P

Objective To study the clinical features,diagnosis and treatment of eosinophilic granuloma of bone(EGB).Methods Twelve cases(8 male and 4 female)of EGB and their medical record,imaging examinations,follow-up data were reviewed,and the lesion sites,symptom and clinical features were analyzed with reference to relative literature.Results Nine unifocal cases were found in the cervical spine(3 cases),the thoracic spine(1 case),the lumber spine(1 case),the femur(1 case),the metacarpal bones(1 case),and the ilium(2 cases).Three multifocal cases were found in the thoracic and lumber spine(1 case),in the femur,the multiple ribs,the skull,the scapula(1 case)and in the skull,the femur,the ilium(1 case).The most common presenting symptom was pain at the lesion site and restricted motion was obviously in the cervical lesion.The case of the thoracic lesions was found neurologic deficit.Osteolytic destruction was found in the radiologic examination in EGB and the periosteal reaction was found in the long bone lesions,and vertebra plana was considered as typical cha-racteristics in the spine lesion.The lesions not in the spine were diagnosed by biopsy,exclusive methods and close following-up were performed in the spine lesions.Two unifocal were healed spontaneously and three were performed with curettage with one bone grafting.Multifocal and the lesions in the spine underwent chemotherapy.All cases were followed up and no recurrence was found.Conclusions EGB is commonly solitary and not seldom in the spine.Topical pain may be chief complaint.Osteolytic image was found in the radiologic examination.Biopsy and exclusive methods combining closely follow-up were used for diagnosis.EGB is self-limited observation,so curettage or chemotherapy can be used in treatment,and prognosis is good.

To observe the effect of Ligusticum wallichii-containing serum on the expressions of Toll-like receptor 4 and myeloid differentiation factor 88 in hepatic stellate cells. Clean-grade SD rats were randomly divided into 5 groups and orally given L. wallichii decoction, colchicine and normal saline for 7 d to prepare L. wallichii-containing serums. Except for the blank group, all of the remaining groups were stimulated with LPS 1 mg x L(-1) for 24 h. After being intervened, the L. wallichii-containing serums were cultured in 5% CO2 incubator at 37 degrees C for 24 hours. The expression of TLR4 and MyD88 were detected by RT-PCR and Western blot. After HSC was stimulated with LPS, TLR4 and MyD88 mRNA and protein expressions were significantly higher than the blank control group (P < 0.01). After being intervened with L. wallichii-containing serum, TLR4 and MyD88 mRNA and protein expressions were notably lower than the model group (P < 0.05 or P < 0.01). In conclusion, L. wallichii-containing serum could regulate the TLR4 signaling pathway and show the anti-fibrosis effect by inhibiting the expression of TLR4 and MyD88 in LPS-induced HSCs.

Objective To explore the relationship between the expression of EIIIA + fibronectin in incised wound of rat’s skin and injury time. Methods The wounding model was established by cutting the dor-salskin of 48 adult SD rats. The rats were sacrificed atthe pre-setinjury time as immediately, 0. 5h, 1h, 2 h, 3 h, 4 h, 6 h, and 8 h. The skin sam ples were taken at the m argin of wound. The expression of the EIIIA + fibronectin was detected by im m unohistochem istry and W estern blotting and the relationship be-tween its expression and injury time was observed. Results The expression of EIIIA + fibronectin was not observed im m ediately. The basal cell of skin began to showpositive expression 0. 5 h after injury. W ith the extension of injury time, positive staining became stronger. The value of relative optical density was gradually increased with prolonged injury time by the W estern blotting analysis. Conclusion The expres-sion of EIIIA + fibronectin could be used for estimation of injury time in the early stage of skin injury.

Combining the speed of two-dimensional detection with the precision of three-dimensional detection, an automatic algorithm based on high resolution CT images is proposed to identify nodules in this paper. Nodule candidates are extracted by a two-dimensional convergence index (CI) filter, then a three-dimensional Hessian matrix detection filter is introduced to reduce false positive lung nodules, Experiments show that the algorithm is effective with a sensitivity of 90% and the false positive lung nodules per slice is 0.33.
