Objective To explore surgical methods of removing polyacrylamide hydrogel (PAHG) and the right time of repairing the deformity of breast after removing PAHG.Methods We operated with endoscopy to remove PAHG through the lower mammary areolar incision.According to injection influence,we made the dicision whether to put the silicon gel prosthesis (hereafter referred to as prosthesis) simultaneously,and to fix the porsthesis,and to rebuild the imframammary fold of breast using biological repair membrane (hereafter referred to as membrane).Results In all 46 patients,39 patients' injection and their envelope were removed entirely.7 patients left part of the envelope because of its thin and wide characters.14 of them accepted prosthesis augmentation mammaplasty simultaneously and 5 of these accepted membrane repair.4 patients received prosthesis augmentation in stage Ⅱ.All patients' incision were primary healing.The incision scars were not obvious.1 patient with breast cancer suffered breast excision; 1 patient who received prosthesis and membrane simultaneously appeared prosthesis displacement after 3 months and fixed again.1 patient who received membrane appeared hydrops in residual cavity,and the membrane was removed finally.Conclusions This method with endoscopy through mammary areolae is necessary for cleaning PAHG entirely.We can use prosthesis to repair the deformity of breast after removing PAHG,and if necessary use membrane to fix the implant and rebuild the inframammary fold of the breast.

Objective: A high-performance liquid chromatographic (HPLC) procedure with a fluorescence detector was developed to rapidly separate ?,?,?,?- tocopherol isomers in human serum Methods: The HPLC system consisted of Inertsil silica column (100-A, 3?m,4.6mm?250mm) and 7% (v/v) methyl-tert- butyl ether in n-hexane as mobile phase . Prior to HPLC, the serum sample wa deproteined by ethanol (BHT 0.0625%) and the tocopherol isomers were efficiently extracted in thei original isomeric conformations using n-hexane-ethyl acetate (5:1) in the presence of 2,6-bi-buty p-methylphenol (BHT). Result: The quantification limits, defined as the lowest quantitatively measurable concentration of the different compounds (ng/ml) are calculated according to the experiment:?-tocophero 1.0,?-tocopherol 1.0,?-tocopherol 0.5,?-tocopherol 0.5. The recovery rates are between 95%~105% Correlation coefficients are over 0.999 when the concentration is between 5 ng/ml~5 ?g/ml. Conclusion This technique is suitable for assay of tocopherol isomers in human serum at all ages.

OBJECTIVE By investigating the incidence of nosocomial infection with objective monitoring method and prospective overall monitoring method, to analyze the advantage and significance between two methods. METHODS Using the objective monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2003 and using the prospective overall monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2002. All data were analyzed with Stata 7.0 soft. RESULTS There were 100 cases occurring nosocomial infection in 267 neurosurgical operation patients. The patient incidence of nosocomial infection was 37.5% and the rate of nosocomial infection cases was 50.9% with objective monitoring method, that was significant higher than those data coming from May to December in 2002 with 248 cases under prospective overall monitoring method, with which the patient incidence of nosocomial infection and the rate of nosocomial infection cases were 20.2%(50 cases ) and 21.4%(53 cases), respectively . Statistically significant difference was found (P

0.05).The average rate of three times NI prevalence surveys was 5.23% and that of NI prospective overall(monitoring) method in the same months was 6.60%,the statistical difference between them was found(P

OBJECTIVE To investigate the characteristics and risk factors of nosocomial infection(NI) in patients with hematological malignancies(HM),and provide the bases for making the controlling measures of NI.METHODS Using the targeted monitoring to study NI in patients with HM,and recording 14 factors such as the time of hospitalization,chemotherapy,count of leukocyte and absolute neutrophil count(ANC) and so on.The data were analyzed with unifactorial ?2 test and multifactorial Logistic-regression analysis.RESULTS Among 242 patients with HM the prevalence of NI was 35.5%(86/242) and the prevalence of NI time-cases was 52.9%(128/242).Among 86 patients of NI there were 27 patients occurred multiple sites NI(31.4%).The main infection sites were upper respiratory tract,gastrointestinal tract,lower respiratory tract,oral cavity and blood.66.7% Of NI happened in the period of chemotherapy and 7 days after chemotherapy.The time of hospitalization and ANC were independent risk factors of NI in patients with HM.CONCLUSIONS The patients with HM are susceptible population of NI,and NI often occurs in the period of chemotherapy and 7 days after chemotherapy.So medical staff should strengthen monitoring,and shorten the time of patient hospitalization and of recovery of ANC to reduce the prevalence of NI efficiently.

OBJECTIVE To analyze the bacterial distribution and drug resistance in lower respiratory tract nosocomial infection(NI).METHODS To investigate 351 patients suffered from lower respiratory tract NI using the prospective monitoring methods,and doing the pathogenic bacterium cultivation for sputums of 351 patients and then taking the susceptibility test.RESULTS Totally 346 pathogenic bacteria were found in sputums of 351 patients.The major pathogenic bacteria were Pseudomonas aeruginosa,Escherichia coli,Klebsiella and Staphylococcus aureus.ESBLs were 36.0% and 40.0%,respectively in E.coli and Klebsiella,and MRSA were 82.1% in S.aureus.Drug resistances were common in Gram-negative bacilli(GNB) and Gram-positive cocci.Piperacillin/tazobactam and cefoperazone/sulbactam and imipenem were the most sensitive for GNB,S.aureus,S.epidermidis and Enterococcus were all sensitive to vancomycin.CONCLUSIONS Drug resistance of the pathogenic bacteria in lower respiratory tract NI is common,so it′s necessary to emphasize pathogenic bacterium monitoring and use the antibacterials exactly.

A method for the determination of B6-pyridoxamine (PAM), pyridoxal (PAL) and pyridoxine (POL) by RPLC was proposed. The procedure included the addition of 0.1M H2SO4 to the sample, hydrolysis for 30 min at 120℃, centrifuging, filtration and direct analysis by ODS Cl8 column. PAM, PAL and POL were completely separated, when the flow rate of the mobile phase (pH2.0-2.1) was 1.0-1.5ml/min. Quantitation by a fluorescent detector was performed with Exc: 293 nm and Em: 395 nm. The recovery ranged from 99 to 103% with CV 5.0-5.3%. The method was simple, rapid, sensitive and reproducible.

Objective To observe the improvement effects of Qingshen Granule on the life quality of chronic kidney disease (CKD) patients with damp-heat syndrome. Methods The CKD patients with damp-heat syndrome were randomly divided into experimental group and control group. The control group was treated with Western medicine, and the treatment group was treated with Qingshen Granules additionally for 12 weeks. SCr and eGFR were observed before and after treatment, and the life quality was investigated by KDQOL-SFTM1.3. Results Actually 156 cases were completed, including 77 cases in the treatment group and 79 cases in the control group. The total rate of curative effect was 81.82% (63/77) in teatment group, and (63.29%, 50/79) in control group, with significent difference (P<0.05). Multivariate linear regression analysis indicated that gender, education level, TCM syndrome score, CKD stage, eGFR and Hb level could affect the life quality. The scores of KDQOL-SFTM and its containing the MOS item short from health survey (SF-36) and kidney disease targeted areas (KDTA) were significantly improved after treatment in experimental group (P<0.05), while the scores in control group were with no significant improvement. The improving effects of PCS, and SPL, SLEEP, PS in KDTA in treatment group were significantly superior to those in control group (P<0.05). The scores of life quality in effective and stable cases increased significantly after treatment compared with before treatment (P<0.05). Conclusion Qingshen Granules can effectively improve the life quality of CKD patients with damp-heat syndrome, and the effect is not dependent on the improvement of laboratory indexes (renal function).
