The complement system is known to be involved in the pathogenesis of the skin lesions in pernphigus vulgaris, bullous pemphigoid, dermatitis herpetiformis, epidermolysis bullosa acquisita, and systemic lupus erythematosus. Authors examined the skin specimens of each disease cases, who did not show any evidence of complement deficiency, to determine the deposition of complement components(C4, C3, Chb-9) and their inhibitors(C4bp, Factor H, S-protein) by modified direct immunofluorescence. We also looked at the staining pattern and localization, for further insights of their pathobiologic contributions in each disease. The findings of deposits of complement components up to C9, as well as inhibitor proteins at the primary histopathologic sites, in the majority of those cases, may indicate that the complement system, to certain extent, involves the inflamrnatory reactions in these diseases. The co-localization of C5b-9 and S-protein could be regarded as the consequence of in situ formation of SC5b-9 complexs or as the result of non-lytic adsorbed complexes of fluid phase SC5b-9. The pathologic role of the complement seems to depend mostly on the complement-fixing biologic property and the amount of the tissue bound immune complexes, which are often heterogeneous to different diseases and among different patients.

OBJECTIVE: To evaluate the therapeutic effect of multi-plane operations in treating obstructive sleep apnea-hypopnea syndrome (OSAHS). METHOD: One hundred and fifteen patients with OSAHS diagnosed by polysomnography were treated with uvuplopalatopharyngoplasty. Eighteen of them were treated combining with nasal septal construction. Twenty six patients also received nasal septal construction and partial inferior turbinectomy. One patients also received Genioglossus advancement and partial resection of corpus linguae. Five patients also received partial resection of corpus linguae. Some patients with the nasal disease and/or the lingual hypertrophy; AHI > 40 and/or BMI > 30 are received tracheotomy before general anaesthesia. RESULT: According to the postoperative follow-up 43 patients, were cured, 46 patients were improved, 26 patients were invalid, the effective power was 77.4%. CONCLUSION The operative effective power were increased by multi-plane operations in OSAHS patients. The serious complication were prevented through tracheotomy before general anaesthesia in multi-plane operations of severe OSAHS.

Objective To design two-point two-line vein pricking for avoiding pain for patients and blood osmosis out of the vein caused by the high-pressure and fast-speed of the current high-pressure injector.Methods 19G butterfly-wing vein transfusion needle in the length of 19mm was used.The first point was needled with the needle tip under the skin and the first needling line was above and parallel the blood vessel in the length of 10-12mm.The second point was needled,with the second needle tip and needle line in the blood vessel,and the length of needling is 7-9mm.Results 100 persons were subjected.All the contrast medium and the physiologic saline were injected in vein in 98 persons,among which 2 had little hard tubercle in injecting area.Conclusion The two-point two-line vein pricking is safe for high pressure injector injecting in vein,and can prevent blood osmosis out of the vein.

ObjectiveTo investigate the immune tolerance function and significance of allogene bone marrow injection to the small intestines transplantation of rats.MethodsInbreeding line rat F344/N and Wistar/A were selected to perform heterotopic graft of the whole small intestine. 7 days before allogene transplantation, donator bone marrow cells (BMC) were injected into thymus of acceptor (the testing group). According to the isogene and allogene rat transplant model, it was comprehended whether injecting allogene donator marrow into acceptor thymus could decrease the acute rejection after transplantation.Results3, 5 or 7 days after allogeneic rat dystopia whole small intestine transplantation, typical reject reaction appeared, but there was no reject reaction in isogenome and testing group. 3 days after allotransplantation, serum soluble interleukin-2 receptor (sIL-2R) and tumor necrotic factor-α (TNF-α) levels were significantly higher than the other groups (P<0.01). The level of serum sIL-2R and TNF-α in the allogene marrow injecting group were only slight higher on the 3rd or 5th day, and getting downtrend, and there was no significant difference compared with isogenic transplantation group.ConclusionAllogenic donator bone marrow intrathymic injecting into acceptor 7 days before small intestina transplantation, can reduce the reject reaction after the grafting. The levels of serum sIL-2R and TNF-α can be selected as a sensitive early diagnosis index of acute rejection after small intestine transplantation.

OBJECTIVETo observe the protection effect of Ligustrazine Hydrochloride (LH) on coagulation reaction and inflammation reaction in single valve replacement patients with rheumatic heart disease undergoing cardiopulmonary bypass (CPB).

METHODSTotally 40 patients undergoing single valve replacement were recruited in the study and randomly assigned to the two groups, the treatment group and the control group, 20 in each group. In treatment group LH (3 mg/kg) was intravenously infused from the jugular vein. LH (3 mg/kg) was also added in the CPB priming. In the control group LH was replaced by equal amount of normal saline. Endothelial micro-particles (EMP) count was detected before CPB, 30 min after CPB, 1 h and 24 h after CPB finished. The coagulation reaction time (R), coagulation time (K), clotting formation velocity (alpha angle), maximum amplitude (MA), coagulation index (CI), platelet (PLT), hypersensitive C reactive protein (hs-CRP), IL-6, and IL-10 were detected before CPB, 1 h and 24 h after CPB finished.

RESULTSThere was no statistical difference in aorta arresting time, period of CPB, post-operative drainage volume, plasma transfusion volume, post-operative respirator assistant time, and hospitalization time between the two groups (P >0.05). Compared with pre-CPB in the same group, the count of EMP was much higher at 30 min after CPB and 1 h after CPB finished (P < 0.01). R and K, hs-CRP, IL-6, and IL-10 increased at 1 h and 24 h after CPB finished (P <0.01,P < 0.05). The alpha angle,.MA, CI, and PLT decreased 1 h after CPB finished (P <0.01). The a angle increased, while CI and PLT decreased 24 h after CPB finished (P <0.05). Compared with the control group in the same period, the count of EMP was lower in the treatment group 30 min after CPB and 1 h after CPB finished (P <0. 05, P <0. 01). R and K values obviously decreased in treatment group 1 hour after CPB finished (P <0. 05), while a angle, MA, CI, and PLT increased (P <0. 05, P <0. 01). hs-CRP and IL-6 decreased in the treatment group 1 h and 24 h after CPB finished (P <0.05), while IL-10 increased (P <0.05). The count of PLT increased 24 h after CPB finished in the treatment group (P <0. 05).

CONCLUSIONLH had certain protection effect on the vascular endothelium undergoing CPB, and lower excessive activation of coagulation reaction and inflammation reaction in patients undergoing CPB.
