Aim The release process of an anticancer agent, DOX_HAP in rabbit liver was observed.Methods DOX and DOX_HAP were separately injectoed into rabbit livers under the guide of B type ultrasound. Dox concentrations in plasma and liver tissue of the rabbits in both groups were measured by fluorescent stectrophotometer and compared. Results The concentration of complex could existed in the liver tissue about 5 d(1 000 ng?g-1) when it was given in a dose of 2 mg?g-1. At the 10 min the concentration in plasma would be reduced about 1/2 as compared with that in the control group. Conclusions The DOX_ HAP complex not only could increase and insist in an effective concentration of DOX at the local injecting area of liver tissue, but also reduce its concerntration in the plasma. Therefore, it could decrease the toxicity and side_effect of DOX.

Objective: To investigate the effects of thyroid motilin (MTL) on migrating motor complex (MMC) in fasting rats. Methods: The distribution and quantitative expression of motilin in the thyroids were detected by immunohistochemistry and radioimmunoassay. We also observed the effect of thyriod motilin on the MMC by recording the gastrointestinal motility in conscious rats. Results: Tail vein injection of MTL increased MMC in antrum and duodenum in a dose-dependent manner, as manifested by increased contraction frequency and amplitude (P<0.05, P<0.01). However, the contraction frequency and amplitude were significantly decreased after injection of MTL-R antagonist GM109(P<0.05). GM109 could obviously block the promoting effect of MTL on MMC. Removing left thyroid significantly increased MMC cycle, contraction amplitude, and decreased contraction frequency (P<0.05). Injection of anti-MTL serum into the thyroids could significantly promote MMC and increase the frequency and amplitude of contraction (P<0.05). Immunohistochemistry demonstrated that motilin immunoreactive (MTL-IR) cells, together with calcitonin (CT) ,were observed in the thyroids, indicating the expression of MTL in thyroid C-cells. Radioimmunoassay analyses displayed that MTL level in the duodenal mucosa was 128.02 and 100.57 times those in the antrum and thyroid, respectively. Conclusion: MTL is expressed in the thyroid C-cell and participates in the regulation of MMC.

Objective To assess the effect of thoracoscopic surgery under laryngeal mask anesthesia and explore the nursing strategies. Methods Thirty-five patients from April to December in 2014 undergoing video-assisted thoracoscopic surgery (VATS) were given intubation anesthesia and another thirty-five ones undergoing the same surgery in 2015 received laryngeal mask anesthesia. The two groups were compared in terms of surgery conditions, surgery complication and ambulation time. Results No significant differences were found in surgery time or blood loss between two groups (P>0.05). The postoperative waking time in the mask anesthesia group was significantly shorter than that of the intubation anesthesia group (P<0.05), and ambulation time was significantly shortened (P<0.05). The rates of throat discomfort, hoarseness and gastrointestinal reactions were significantly lower. Conclusions Laryngeal mask anesthesia used in small thoracoscopic surgery for airway management is safe and feasible. Combined with training in respiration and limb function, better analgesia and nursing, it can keep away complications related to intubation anesthesia, shorten hospital stay and accelerate postoperative rehabilitation.

Gold nanorods is a capsule-shaped gold nanoparticles. Gold nanorods give rise to two absorption peaks corresponding to their plasmonic modes, transverse mode and longitudinal mode, corresponding to light absorption and scattering along the short and long axis, respectively. The longitudinal surface plasmon resonance can be tuned by adjusting their aspect ratio from the visible to the NIR region and extremely sensitive to changes in the dielectric properties of the surroundings including solvents, adsorbates, and the interparticle distance of the gold nanorods. This unique optical property of gold nanorods opens up fascinating applications in biological and chemical sensors. Optical properties and biomedical application of gold nanorods are introduced, and its future research prospects are discussed.

Objective To investigate the characteristic of autoantibodies of M-type phospholipase A2 receptor (PLA2R) in serum and the glomerular IgG subclass deposits in undetermined atypical membranous nephropathy (MN) patients.Methods From Feb 2004 to Nov 2011,53 cases diagnosed as MN by kidney puneture biopsy in our hospital were included into the study.There were 20 undetermined atypical membranous nephropathy (UAMN),20 idiopathic membranous nephropathy (IMN) and 13 secondary membranous nephropathy (SMN) which were composed of lupus membranous nephropathy (LMN) and HBV related membranous nephropathy (HBV-MN).Clinlical and pathological characteristics were analyzed.The autoantibodies of PLA2R in serum were detected and the glomerular IgG subclass deposits were observed.Results (1) The average age underwent renal biopsy was (37.9±3.8) years of UAMN,(50.1±3.0) years of IMN and (49.5±4.5) years of SMN.The difference in onset average age at disease was significant between UAMN and IMN (P =0.0178).The female/male ratio (F/M) in UAMN,IMN and SMN was 0.8∶ 1,0.7∶1 and 0.6∶ 1(P ＞ 0.05).(2) Compared with SMN,the level of 24-hours urinary protein excretion (3.47 g vs 7.89 g,P =0.023),the ratio of amount urinary protein patients (50.0％ vs 84.6％,P=0.043),the level of serum IgG [(8.40±3.58) g/L vs (10.09±4.69) g/L,P =0.025] and the positive rate of ANA in serum (10.0％ vs 53.8％,P =0.006) in UAMN were all much lower.There were no significant statistical differences in serum albumin,serum creatinine,eGFR,positive rate of HBsAg,HBeAg or HCV,as well as the ratio of hypo-albuminemia and nephrotic syndrome among the three groups.(3) IF positive rate of IgA,IgM and C1q in UAMN were all significantly higher than that in IMN (P ＜ 0.01).There were no significant differences in IF positive rate of IgA,IgM,C1q,IgG and C3 between UAMN and SMN.The IF strength of IgA,IgG,IgM,C3 and C1q in UAMN showed no significant differences between UAMN and SMN.(4) The serum autoantibodies of PLA2R were only detected in 10 cases of IMN group (50％) with all the other cases negative.This detection rate of serum autoantibodies of PLA2R showed significant statistical differences among the three groups (P ＜ 0.01),but no differences between UAMN and SMN (the detection rate in both groups were 0％).(5) IgG1 deposits was the dominant IgG on the glomeruli in UAMN group (40％),as well as in SMN group (76.9％).IgG4 deposits was the dominant IgG on the glomeruli in IMN group (60％).The positive rate of IgG1 and IgG3 in UAMN showed no significant statistical differences when compared with IMN or SMN.The positive rate of IgG2 in UAMN was significantly lower than in SMN (30.0％ vs 69.2％,P ＜ 0.05).The positive rate of IgG4 in UAMN was significantly lower than in IMN (20％ vs 60％,P ＜ 0.05).The positive rate of IgG1,IgG2 and IgG3 in SMN were all significantly higher than in IMN.Conclusions None of the UAMN group had autoantibodies of PLA2R in serum,and IgG1 deposits was the dominant IgG subclass on the glomeruli which indicated the similarity with the SMN group.At the same time,UAMN was significantly different from SMN in clinical manifestations.

Objective To observe the clinical outcome of maintenance hemodialysis patients with hepatitis C viruses(HCV)infection.Methods A retrospective investigation about hepatitis C viruses infection was performed in our hemodialysis centre on December 31,2007.The clinical data including demography,serum transaminase,bilirubin,albumin,anti-HCV antibody,HCV RNA,infection-control procedures associated hemodialysis and ultrasound of the liver was analyzed.Results The prevalent rate of HCV infection in our hemodialysis centre was 20.2%(20/99),The mean age of maintenance hemodialysis patients with HCV infection was(63.3?10.9)years old,the duration on dialysis was(79.9?38.7)months,and the duration of positive serum anti-HCV was(32.6?22.6)months(the longest duration was 103.5 months).16 patients(80%)had blood transfusion history in the patients with HCV infection.Only four cases had viremia of HCV,the serum HCV RNA became negative in one of them spontaneously and in another one after interferon therapy for half a year,the other two of them have viremia now.Most of patients found their serum transaminase elevated transiently and mildly.The age and duration on dialysis of the patients with positive serum anti-HCV were significantly longer than those of patients with negative serum anti-HCV.After strict infection-control procedures were carried out,the new onset cases of HCV infection was significantly decreased(1.2% vs 5.3%,P
