Primary biliary cirrhosis (PBC) is a slowly progressive autoimmune disease of the liver.Studies on the pathphysiology of this disease have demonstrated the immune-mediated destruction of the intrahepatic bile ducts and portal infammation seem to be the result of an intense autoimmune response directed against the autoantigens located in the biliary epithelium.Immunologically,PBC is characterized by the presense of antimitochodrial antibodies,elevated serum IgM and lymphoid infiltration in the portal tract.Indeed,the relationships between IgM and PBC have been a major focus of research on its pathphysiology,which lead to an increased understanding of the abnormal immune responses involved in PBC.This review summarizes data on the biological and clinical significance of Hyper-IgM in PBC,and highlights the potential role of IgM for the diagnosis and treatment of PBC.

OBJECTIVE: To explore the regularity and characteristics of ADR induced by levofloxacin. METHODS: Retrieved from, CHKD of CNKI and Wanfang database, a total of 205 literatures about levofloxacin-induced ADR were collected and analyzed statistically in respect of patients’ gender, age, case history, administration route, clinical manifestation and result of treatment. RESULTS: 483 cases(92.9%) were given levofloxacin intravenously in total of 520 ADR cases. 156 cases were characterized with lesion of skin and its appendants (30.0%), followed by lesion of nervous system (n=133, 25.6%), lesion of cardiovascular system (n=65, 12.5%) and anaphylactic shock (n=45, 8.7%). The earliest ADR occurred within 2 min after administration while the latest occurred in 34 d after administration. 514 cases recovered when drug withdrawal or treatment were taken. However, there were 2 cases of sequelae, 4 cases of death and 62 cases of unexpected serious ADRs. CONCLUSION:ADRs induced by levofloxacin present complicated and various symptoms caused by several factors in which the most serious result in death. Clinical doctors should pay more attention to levofloxacin-induced ADRs.

Objective To discuss clinical results of self-made anatomical dynamic hip lock plate (ADHLP) in treatment of intertrochanteric fractures. Methods ADHLP was applied in 73 patients in-eluding 52 males and 21 females at age range of 19-92 years ( mean 54.7 years). Fractures were caused by traffic accidents in 32 patients, sllp in 21, fall from height in nine and other factors in 11. According to the Evans' s classification system, there were 42 patients with type Ⅰ fractures, 17 with type Ⅱ, nine with type Ⅲ and five with type Ⅳ. Self-made ADHLP was applied to manage various fractures with differ-ent operation strategies. The curative effect of ADHLP was observed for evaluation of ADHLP. Results The operation lasted for mean 60 minutes (40-90 minutes). The volume of blood loss was mean 200 ml (100-400 ml). All patients were followed up for 6-48 months (average 36 months), which showed that the function of hips was satisfactory, with excellence rate of 99%. There were no complications like coxa yam, femoral head eoncis, rotation displacement, iatrogenic fracture, infection or internal fixation break and loosening. Conclusions ADHLP takes advantages of reasonable vitodynamics, wide operation in-dicatioas, convenient operation, minor trauma, fast recovery, stable fixation and few complications for in-tertrochantefie fractures, especial]y osteoporotie and gemntal patients.

Objective To analyse the microvascular density(MVD) and CD44v6 expression in uterine cervical squamous carcinoma to evaluate their clinical significance. Methods Immunohistochemical staining (LSAB method) by using antibodies against CD 34 and CD44v6 was performed on archival specimens of 50 cases of human uterine cervical squamous carcinoma and 10 cases of normal cervical tissue. Results MVD was greater in metastatic tumors than that in nonmetastatic tumors and normal control. The expression of CD44v6 was higher in metastatic tumors than that in nonmetastatic tumors and normal control. MVD and CD44v6 expressions were significantly related to lymph node metastasis(P

Objective To investigate the occurrence of intraoperative occupational exposure to blood among sur-geons in a hospital,so as to make effective precaution measures.Methods Combined with questionnaires,the mo-nitoring data of occupational exposure to blood among surgeons from June 2011 to June 2013 were analyzed statisti-cally.Results A total of 49 surgeons sustained 115 times of occupational exposure to blood,including 42 times (36.52%)in general surgery surgeons,36 (31 .30%)in orthopedic surgeons,31 (26.96%)in obstetrics and gyne-cology surgeons,and 6(5.22%)in urinary surgery surgeons.The main occupational exposure were sharp injuries (n=71 ,61 .74%),blood and body fluid splashing were 44 times (38.26%);the top two exposed sites were hands (49.57%)and faces (17.39%).88.70% of exposed cases were given emergent treatment,and 55.65% of exposed cases were reported.The follow-up found no surgeons were infected after the prompt and correct treatment. Conclusion Surgeons are at high risk of occupational exposure.Occupational precaution should be strengthened, occupational awareness and ability of HCWs should be enhanced,and post-exposure treatment should be improved.

Objective To evaluate the anesthesia and perioperative treatment for simultaneous liver-kidney-pancreas transplantation. Methods The preoperative preparation included improvement of the hepatic function, alleviation of uremia and control of blood glucose level. General anesthesia was employed and maintained with isoflurane combined with intermittent intravenous administration of midazolam, fentanyl and vecuronium. Dopamine and low dose of epinephrine were used to maintain arterial blood pressure if necessary. The parameters of blood coagulation, the indexes of hepatic and renal function, blood glucose and amylase levels in blood and urine were surveyed regularly. The treatment was adjusted according to the results of tests mentioned above. Results The circulation was stable and blood gas was normal in the course of surgery. The concentration of blood glucose was higher at the end of the operation than that of pre-operation. Normal hepatic and pancreatic function was achieved about a week after operation, while the renal function showed no satisfactory improvement. The patient was given hemodialysis until the second transplantation of kidney. Three days later, the renal function recovered to normal. Up to the present, all the grafted organs showed good function. Conclusion Appropriate preoperative preparation, optimal anesthetic procedure and management, perfect protection of function of multiple organs, and maintenance of stable hemodynamics and homeostasis were the key points of successful anesthesia and management for simultaneous liver-kidney-pancreas transplantation.

Objective To reproduce a simple and practicable animal model of rheumatoid arthritis(RA)for evaluating the therapeutic effects of recombinant human interleukin-1 receptor antagonist(rhIL-1Ra).Methods The animal model of RA was reproduced in Wistar rats by intradermic injection of an admixture of bovine type Ⅱcollagen and Freund's complete adjuvant on the foot pad,tail,and back of the rats and the injections were repeated 7 days later.Results Two weeks after the second injection,all the extremities were markedly swollen.The diameter of ankle joints,the level of TNF-? in serum,and the size of the paws were increased obviously.There was destruction and absorption of the bone trabeculae of distal end of the tibia.There was also necrosis and fibrosis of cartilage of the joints.The articular space was narrowed.Thus RA model was successfully reproduced in rat.Conclusion Bovine type Ⅱcollagen and Freund's complete adjuvant were a favorable agent for the reproduction of RA model in rats.

Objective To evaluate the therapeutic effects of combined recombinant human IL-11(rhIL-11) and recombinant human G-CSF (rhG-CSF) on the neutron-irradiated dogs. Methods 18 male beagle dogs were divided into radiation control group (C, n=7), symptomatic treatment group (S, n=4), and combination therapy group (T, n=7). All dogs were exposed to total body 2Gy 90% neutron radiation. From the first day after radiation, the animals of group T received rhG-CSF 10?g/(kg?d) and rhIL-11 50?g/(kg?d) subeutaneously for 14d and 21d respectively. The cell counts of peripheral blood and CFU-GM of bone marrow were carried out. Results All animals of group S and T survived, however, the survival rate of group C was only 57%. The cellcounts of T group peripheral blood cells (white blood cell at any time point , the platelet and red blood cell of recovery phase) were higher than that of C or S group. The count of T group bone marrow CFU-GM was 6 fold higher than that of group C or S on day 1, and still 1.75, 1.46 fold higher than that group C or S, respectively, on day 33. Conclusion the combination therapy of rhIL-11 and rhG-CSF significantly raised the white cell and platelet counts in ARS dogs induced by neutron irradiation by accelerating the recovery of bone marrow hematopoietic function.
