Objective To analyze the causes and explore suitable treatments for the complica-tions induced by polyacrylamide hydrogel (PAHG) injection for augmentation rhinoplasty. Methods The causes of the complications of 52 cases who accepted PAHG injection for augmentation rhinoplas-ty were analyzed and summarized. All the patients were treated by surgical operations to remove the injected PAHG. Results The complications included infection, granuloma, skin ulceration, bad shape, pain and serious psychological stress. Each case had 1 to 4 complications. Satisfactory results were obtained after suitable treatments. Some cases had silicone or expanded polytetrafluoroethylene implant augmentation rhinoplasty at the same time or secondary to the PAHG removal. A few cases had sequelae and long time psychological stress or tend pain of nose. Conclusions The complications induced by PAHG injection for augmentation rhinoplasty are various, and may relate to the inherent character of PAHG and the anatomic features of the nasal soft tissue. Surgery can remove the PAHG as completely as possible, which is a better method to treat the complications of PAHG injection for augmentation rhinoplasty.

Objective To study the effect of morphine used in epidural anesthesia on puerpera after cesarean section and the safety of morphine to neonate. Method One hundred puerpera undergone cesarean section were randomly divided into test group and control group with continuous 2% lidocaine epidural anesthesia, as soon as the operation were finished, 2 mg morphine was injected into vacum epidurale for test group, nothing for control group. Colostrum and plasma, urine samples of puerpera and neonate were collected, morphine and metabolite level were tested by GC-MS and FPIA. Result Morphine concentrations ranged from 0.05). Conclusion As the epidural analgesia medicine after cesarean section, morphine has no side-effect to neonate and is safe to neonate.

Objective To investigate the changes of plasmacytoid dendritic cells (pDC) in peripheral blood of patients with systemic lupus erythematosus(SLE) and its roles in the pathogenesis of SLE.Methods The level of pDC and the expressions of CD32,CD40,CD86,CD62L and CXCR4 were analyzed by flow cytometry.The concentrations of IFN-α in serum were detected by ELISA assay.Results The levels of circulating pDC were significantly decreased in SLE patients compared with healthy controls.Moreover,the pDC levels in active SLE patients were lower than those in inactive SLE patients,and compared with the primary group,the pDC levels were increased in the treatment group.The levels of pDC showed a significant decrease in SLE patients with arthritis,proteinuria or leucopenia in comparison with patients without those manifestations,showing a negative correlation with proteinuria.The expressions of cell surface molecules including CD32,CD86,CD62L and CXCR4 on pDCs were significantly increased in SLE patients compared with healthy controls,and the levels of pDC were negatively correlated with the expressions of CD32 and CXCR4 in patients with SLE.The concentrations of IFN-α in serum of patients with SLE were significantly higher than those in healthy controls,and the levels of pDC were positively correlated with the concentrations of IFN-α in patients with SLE.Conclusion The level of circulating pDC in patients with SLE was remarkably reduced,but the expressions of molecules involved in cell activation and migration were upregulated,accompanied by enhanced IFN-α production,which might promote the onset and progression of SLE.

Objective To observe characters of sputum of patients with tracheotomy by heat and moisture exchanger(HEM)undergoing hyperbaric oxygen therapy(HBOT)in multi-person chamber.Methods In randomly block design,239 patients were selected and received HBOT using HEM combined with L-shape tube(group HEM,n=128)and by L-shape tube(group L,n=111)respectively.The characters and volume of sputum,times of sucking sputum and cases of sealing/extubation of tubes were assessed over first and tenth sessions of HBOT.Results The times of sucking and volume of sputum over first session of HBOT in the group HEM were more than those in group L.The sputum was changing from ropiness over first session to tenuity over tenth sesion(P＜0.01).Cases with sealing/extubation of tubes in group HEM were more than those of group L(P＜0.01).Conclusions It is helpful to humidify and discharge deposited sputum of patients over routine hyperbaric oxygen by HEM.And the case8 of sealing/extubation of tubes are also reduced.

Objective To study the roles of TLR2 and TLR4 in the progress of invasive pulmonary aspergillosis(IPA) in experimental mice.Methods The mice were divided into three groups including the group of normal mice,the group of normal mice infected with A.fumigatus and the group of IPA mice.The mice were sacrificed at four time points(8 h,24 h,48 h and 72 h) after infection.The lung tissues from each group were collected for pathological analysis and RT-PcR for detecting the expression level of,TLR2,TLR4 and β-tublin.The ratio of density value of band of each PCR product on electrophoresis to the density value of β-tublin was used to evaluate the expression level of each gene like TLR2.TLR4 and TNF-α.Re-suits The pathological analysis showed the normal structure and no inflananatory reaction in the lungs in the group of normal mice.The infiltration of inflammatory cells,weak injuries and no germination of spore into hypha in the lungs of normal mice infected with A.fumigatus,and serious injuries like destruction of alveolar structure,bleeding,infiltration of inflammatory cells and germination of spore into hypha in the lungs of IPA mice.The expression level of TLR4 at 8 h,24 h,48 h and TNF-α at 24 h and 48 h were lower in IPA mice than that in healthy mice with infection(P<0.05).Conclusion There was low expression of TLR4 and TNF-α in IPA mice lung tissues.Typical pathological injuries in the lungs and germination of spore into hy-pha in IPA mice were observed by the microscope.

Objective To investigate the effects of cinnamaldehyde and citral on DNA and RNA of Aspergillus flavus and A. fumigatus cells and their mechanisms. Methods A. flavus and A. fumigatus were incubated on Czapeks agar plate (treated with cinnamaldehyde and citral at different concentrations) at 26.5 ℃ for 3—6 d. The normal and treated cells were observed by laser scanning confocal microscope (LSCM) and image analysis to describe the DNA and RNA levels by quantity and localization. Results DNA and RNA levels were changed greatly and multinucleate coniospores appeared in the treated cells. Conclusion Cinnamaldehyde and citral have directly or indirectly interfered the conventional synthesis of fungal hereditary DNA and RNA and normal differentiation of conidiophore in A. flavus and A. fumigatus, thus inhibiting the normal cell cycle and the growth and propagation of fungi.

Objective To investigate the relationship between the anti-phospholipid antibodies (APLs)and activated protein C resistance (APCR). Methods The response to activated protein C (APC) was studied by an APTT-based (clotting) assay with a Stago autoanalyzer and expressed as the ratio between the APTT obtained in the presence and absence of exogenous APC. APC sensitive ratio higher than 2 was regarded as APCR. Anti-?2-glycoprotein Ⅰ (?2GP-Ⅰ) antibody and anti-cardiolipin antibodies (ACL) were measured by an enzyme-linked immunosorbent assay (ELISA). Lupus anticoagulant (LA) was tested by activated partial thromboplastin time (APTT). Results The existence of LA and acquired APCR showed significant correlation (?2=16.332, P=0.008). Acquired APCR was significantly associated with the presence of anti-?2GP-Ⅰ antibody (?2=6.179, P=0.012), but not ACL. The presence of APCR was associated with an increased frequency of history of thromboembolic events and/or recurrent abortions (?2=7.347, P=0.01). Conclusion This study suggests that APCR is linked to the presence of LA and anti-?2GP-Ⅰ antibody. APLs may interfere with the activation of protein C. APCR phenotype may be a major risk factor for thrombophilia in patients with APLs. Combined detection of APLs has the potential value for predicting thrombosis.

0.05).The adverse reaction rate was 14.0% (7 case) in the treated group and 15.6%(7 cases) in the controlled group. There was no significance difference between the two groups (P=0.83). But the adverse reactions were more tolerable in LEF group than in MTX group. Conclusion This study suggests that LEF is an effective and more safe drug for active rheumatoid arthritis in our country.
