Objective To investigate prophylaxis and therapy of early complications following relatives' partial live small bowel transplantation.Methods Four relatives' partial live small bowel transplantations were carried out.Among the 4 patients,there were 3 cases of short intestine syn- drome and one case of non-function of small bowel caused by the absence of nerve ganglion of small in- testine.More than 4 antigens of HLA were completely matched between donators and receptors.In- testines of donators were got from terminal ileum with the length of (150?10) cm.After operations, tacrolimus (FK506),mycophenolate mofetil (MMF),and methylprednisolone were used to prevent rejections.Measures such as use of anticoagulation,improving microcirculation and albumin infusion, aimed at regulating the function of blood coagulation and preventing bleeding and formation of thrombus at anastomotic stoma;famotidine and omeprazole were used to prevent irritable ulcer;use of the third generation of cephalosporins antibiotics,ganciclovir and fluconazol could prevent bacteria,vi- rus and eumycete infections;disinfection and care of easily-infected organs were emphasized;receptors were encouraged to get out of their beds to move frequently;glutamine and enteral nutrition were used early to promote recovery of intestinal function.Results Three days after operation,one patient's lung was infected with baumanii,and the infection had been under control after being treated with the third generation cephalosporins antibiotics;five days after operation,haematoma was detected on an- other patient and was cleared through the second operations growth of eumycete was found in 2 pa- tients' excretion and secretion from enteron,and their situations were improved with fluconazol;acute rejections of the 4 patients were detected 20 days after operation and reversed by the increased use of FK506 combined with methylprednisolone.Among the 4 patients,2 of them have survived for a long time,and the first patient has survived for 6 years and 8 months till now and the other one for 3 years and 2 months;furthermore,other 2 patients respectively died of infections 5 months and 35 days after the operations.Conclusion Because of special constitution of intestine,early complications of rela- tives' partial live small intestine transplantation are frequent and complicated.Therefore,prophylaxis and therapy of early complications are crucial to the success of the transplantation.

AIM:To compare the two techniques of pre-chop and non-pre-chop, and discuss the technical advantages of the capsulorhexis forceps assisted pre-chop.METHODS:Totally 149 cases of age-related cataract were randomly divided into using pre-chop (Group A) and non-pre-chop (Group B) techniques groups, for Group A patients received phacoemulsification after pre-chop by using capsulorhexis forceps.The ultrasonic energy, average phacoemulsification time, intraoperative complications, 1d, 1wk uncorrected visual acuity (UCVA) and 1d, 3d,1wk postoperative corneal edema were recorded and compared.RESULTS:The subgroups of the same group of nuclei were compared in the two groups.The ultrasonic time in Group A was lower than that of Group B, and the difference was significant(P<0.01).Also the corneal edema in the former was lighter than that of the latter(P<0.05).There was difference in uncorrected visual acuity(UCVA) between groups(P<0.05).CONCLUSION:Compared with non-pre-chop, the time of ultrasound in pre-chop group was shorter, the degree of corneal edema was lighter and early postoperative UCVA was better.

Objective:To determine the derivative chromosome 9 by the method of detecting the ASS gene,and to explore the relationship between the deletion of derivative chromosome 9 and the efficacy and prognosis of the chronic myeloid leukemia (CML)patients. Methods:The materials of 34 CML patients with positive BCR-ABL fusion gene whose ASS genes were detected were retrospectively analyzed. All patients were treated with Extra-signal (ES)probe to detect the derivative chromosome 9.All patients were divided into two groups according to whether they carried the derivative chromosome 9.The blastic phase or the accelerated phase rates in two groups were compared by using Fisher exact probability. Results:All patients were detected by FISH (BCR-ABL ES probe),and all the BCR-ABL fusion signals were positive.6 of 34 patients were found the deletion of ASS gene, among them 1 case blonged to chronic phase,and 5 cases developed into blastic phase or accelerated phase. In the patients without ASS gene deletion,there were 22 cases in chronic phase,and 6 cases in plastic phase or accelerate phase,there was significant difference of blastic phase rate/accelated phase rate between them (P<0.05).A total of 26 patients were treated with tyrosine kinase inhibitors (TKI).5 of 26 patients belonged to the ASS gene deletion group,1 of 5 patients treated with TKI got molecular remission,4 of 5 patients developed into blastic phase or accelerated phase.21 of 26 patients belonged to the group without ASS gene deletion,and among them,19 cases got molecular remission,2 cases developed into plastic phase or accelerated phase after treatment of TKI,there was significant difference between them (P < 0.05 ). 6 patients were treated with traditional chemotherapy (hydroxyurea,interferon);1 of 6 patients belonged to the ASS gene deletion group,finally developed into the blastic phase or accelerated phase;5 of 6 patients belonged to the group without ASS gene deletion,2 cases got the hematological remission,and 3 patients developed into blastic phase or accelerated phase after treatment,and there was no significant difference of blastic phase rate/ accelerated phase rate between them (P > 0.05 ). Conclusion:The CML patients with derivative chromosome 9 (ASS gene deletion)prone to get disease progression, and have a higher proportion in the blastic phase or accelerated phase patients.Derivative chromosome 9 is related to the bad treatment efficacy of TKI and the poor prognosis of CML.

Hemopexin (HPX) is a plasma protein with the strongest binding capacity to heme and widely involved in modulation of a variety of physiological and pathological processes. The main physiological function of HPX is to bind and transport free toxic heme. Recent studies indicate that HPX also plays roles of anti-oxidant, anti-apoptosis, immune regulation and organic protection. In addition, HPX participates in regulation of cell differentiation and extracellular matrix reconstruction. In recent years, a great deal of progress has been made in studies of the mechanisms of HPX protective effects and on possible clinical application. In the past few years, especially, a number of proteomic studies have demonstrated that HPX could be served as positive molecular biomarkers for cancers of lung, liver, kidney, colon, and uterine myoma as well as osteoarthritis. In this review, recent progress in the biochemical characteristics and function of HPX and its possible clinical applications are summarized.
