With the development of the cross-correlation technique in surgery, the transplantation and vi-cariousness have become more and more important in repair surgery and reconstructive surgery. A nice bio-material could replace the related tissue or organ of human body, support the homologous function of organ-ism,and accelerate the process of self recovery and autotherapy. This review is about the status of research and application of biomaterial in surgery.

A nice biomaterial,which could replace the correlated tissue or organic of human body,supports the homologous function of organism,and accelerates the process of self recovery and autotherapy in the same time.The application of biomaterial in clinic,not only have the chemical characters and function of vitodynamics to match,but also be with nice biocompatibility and practical safety.Some development of biomaterial and the biocompatibility of it in this paper was reviewed,and the application status in the cardiothoracic surgery in recent years.

Objective To understand the blood lipid levels and abnormal conditions of the senior citizens aged over 65 in Shenz-hen city and provide a scientific basis for prevention of dyslipidemia.Furthermore,to investigate the influence of dyslipidemia on the result of hemoglobin(Hb).Methods Through random investigation of 252 samples aged over 65 in Shenzhen on their fasting serum TC,TG,HDL-C,LDL-C and Hb in peripheral venous blood and analyze current situation of dyslipidemia.By comparing the groups with dyslipidemia (A,B,C,D group)and group with normal blood lipid (E group),investigation on the influence of dyslipidemia on Hb was conducted.Results The total prevalence of dyslipidemia was 48.02%,TG,TC,LDL-C,HDL-C prevalence was 26.19%, 32.14%,25.79%,17.86% respectively.The average value of TG,TC,LDL-C,HDL-C respectively was(1.53 ±0.66),(4.79 ± 0.90),(2.96±0.77),(1.28±0.26)mmol/L.The prevalence and the difference of average level on TG between male and female was significant in statistics(P <0.01).There had been statistical differences of Hb among groups A,B and group E(P <0.05 ). Conclusion The total prevalence of dyslipidemia of people over the age of 65 in Shenzhen is higher than average,especially in TC. There is interference on Hb when TG,TC is abnormal.Therefore,emphasis should be laid clinically and related rectification must be carried out to ensure the accuracy of Hb.

This article summarized clinical studies and mechanism research literature on acupuncture in treating chemotherapy induced nausea and vomiting in the latest 20 years. It found that the domestic and foreign researches tend to regard acupuncture as an effective method for the treatment of chemotherapy induced nausea and vomiting, which still requires further high-level clinical researches to verify. Acupuncture may prevent and treat chemotherapy induced nausea and vomiting through multiple mechanisms, and studies on these mechanisms show extensive research prospect.

BACKGROUND: Lower urinary tract abnormality (LUTA) can lead to end-stage renal disease (ESRD). However, insufficient attention has been paid to these patients in China, and they are usually thought unsuitable for kidney transplantation because of high incidences of graft dysfunction and septic complication.OBJECTIVE: To explore the characteristics and postoperative follow-up after kidney transplantation in four patients with LUTA.DESIGN, TIME AND SETTING: A retrospective analysis of LUTA cases was performed from July 2002 to June 2006 at the Organ Transplantation Center of Chinese PLA, Second Affiliated Hospital of General Hospital of Chinese PLA.PARTICIPANTS: Four ESRD cases of LUTA, who received allograft kidney transplantation.METHODS: Four cases of LUTA experienced detail evaluation before kidney transplantation. Ureter was reimplanted into the original bladder during transplantation and suprapubic cystostomy was performed as urinary drainage.MAIN OUTCOME MEASURES: Patient and graft survival, graft function, urinary tract infection (UTI) and graft rejection were supervised after surgery and quality of life was evaluated.RESULTS: Two patients recovered well with normal renal function and no rejection. Despite the moderate but easily controlled UTI, they handled the urinary diversion well and were satisfied with the quality of life. One patient experienced an acute rejection 17 days after transplantation and survived with functional graft until now after the rejection was reversed. One patient lost the graft for repeated hemorrhage at the site of vascular anastomosis, and then returned to hematodialysis.CONCLUSION: Kidney transplantation is suitable but special for patients with LUTA. Careful evaluation before transplantation, suitable urinary drainage and rigorous follow-up after surgery are keys to the success of kidney transplantation for this subgroup of patients.

Objective To explore the clinical manifestations and the characteristics of images of indocyanine green angiography (ICGA) and fundus fluorescein angiography(FFA) of multifocal choroiditis. Methods Eight patients (10 eyes) with multifocal choroiditis were gathered. The clinical manifestations and the images of ICGA and FFA were analyzed. Results Foci of multifocal choroiditis were found in posterior pole and peripheral areas of ocular fundi of all of the 10 eyes. The images of ICGA revealed hypofluorescence in focal area. The images of FFA showed hypofluorescence at the early phase and fluorescein leakage at the late phase in the active focus, and fluorescein staining and window defect fluorescence in the inactive focus. Conclusions The clinical manifestations of multifocal choroiditis varied with disease course, location and numbers of the lesions. ICGA and FFA can show the development of the disease clearly, which may guide the treatment.

Objective To study the effects of PVC_U pipes on tap water quality.Methods The safty assessment on a certain brand of PVC_U pipes was carried out. A residential quarter with this kind of PVC_U pipes for water supply was selected. Drinking water samples were collected from 2 pipeline inlets outside the quarter and 4 outlets inside the apartment. The indexes such as organoleptic indexes, general chemical indexes, heavy metals, organic compounds, radioactivity of the water samples were determined. The toxicological tests were carried out also. Results The sanitary indexes of the water samples for immersing PVC_U pipes except the content of ferrite accorded with the related national standards. No significant differences were observed in sanitary indexes of the water samples collected from inlets and outlets of pipeline for the apartment. The organic extracts of the water samples from the outlets of water supply system in the apartment showed negative results in acute oral toxicity test, 30_day feeding test, micronucleus test and Ames test. Conclusion PVC_U pipes were safe and hygenic for drinking water supply.

ObjectiveTo investigate the efficacy of acupuncture point injection for fine motor functions in children with cerebral palsy.Methods57 children with cerebral palsy were treated by acupuncture point injection combined with occupational therapy. The efficacy was evaluated by the Peabody Developmental Motor Scale-Fine Motor (PDMS-FM).ResultsThe fine motor quotient (FMQ) of 34 children (59.7%) elevated. The raw scores of grasping subtest (Gr) elevated in 45 children (78.9%) and the raw scores of visual-motor integration (VI) elevated in 53 children (93.0%).ConclusionThe efficacy of acupuncture point injection combined with occupational therapy is significant in children with cerebral palsy.

Aim Poly (methoxypolyethyleneglycol cyanoacrylate-co-hexadecyl cyanoacrylate) (PEGPHDCA) and PHDCA niosomes were prepared and the influence of the PEG chain length on the niosomes physicochemical characteristics, complement consumption and phagocytic uptake were studied. Methods The physicochemical parameters of PEG-PHDCA niosomes were characterized in terms of particle size, zeta potential, surface PEG density and fixed aqueous layer thickness. The relationship between physicochemical characteristics and in vitro complement consumption and phagocytic uptake was further illustrated. Results Experimental results showed that PEG10000-PHDCA had most loose structure and least PEG surface density among three groups. Configuration simulation through fixed aqueous layer thickness confirmed that PEG folding and less flexibility of the PEG chains of PEG10000-PHDCA niosomes were accountable for its poor stealth effects. Compared with PEG2000-PHDCA, PEG5000-PHDCA showed a thicker fixed aqueous layer (FALT) of 4. 20 nm, less negative zeta potential of -10.03 mV, and consumption and phagocytic uptake. Conclusion Excessive chain length of PEG was not necessary for stealth effects of PEG-PHDCA niosomes. PEG5000-PHDCA niosomes had best effects on evading complement consumption and subsequent phagocytic uptake.
