The recombination clones contained CFP, LTB-ST foreign gene were screening by PCR using individual bacterial colonies as template, the aimed band was amplified from positive clones, the result was as well as plasmid PCR. The selecting of agrobacterium transformed with recombination plasmid could also use this method of PCR screening of individual bacterial colonies. The result of individual bacterial colonies PCR was as well as that of PCR using bacterial solution as template. It showed that the method individual bacterial colonies PCR was an efficient, easy one that characterized recombination clones.

BACKGROUND: Individual three-dimensional (3D) scaffolds can be constructed by 3D printing via Computer Aided Design based on the given anatomical measurements of related tissues. A rapid and accurate reconstruction of bone, cartilage, muscle and vessel also can be achieved by 3D printing; however, many problems still remain unsolved.OBJECTIVE: To summarize the principle and classification of 3D printing, the classification, characteristics and histocompatibility of scaffolds through reviewing the articles addressing 3D printing applied in bone tissue engineering,thereby providing theoretical foundation for the study on the construction of tissue-engineered bone.METHODS: PubMed and CNKI databases were retrieved for the literatures regarding the application of 3D printing technology in bone tissue engineering published from January 2001 to January 2017 using the keywords of three-dimensional printing, rapid prototyping manufacturing, bone tissue engineering in English and Chinese,respectively. Finally, 30 articles were reviewed and discussed in accordance with the inclusion and exclusion criteria.RESULTS AND CONCLUSION: The microstructures of normal tissues can be reconstructed and seed cells are printed on the 3D scaffolds synchronously by 3D printing technology. Moreover, the scaffold degradation and cell differentiation are synchronous, which contributes to tissue repair. Biological ceramics have been widely used in bone tissue engineering because of its good biocompatibility and mechanical properties. However, the urgent problems such as angiogenesis and cellular signal transduction still need to be addressed.

Objective To investigate the risk factors of electrocoagulation syndrome after endoscopic submucosal dissection (ESD) in patients with colorectal lesions.Methods Clinical data of 145 patients with colorectal mucosal lesions undergoing ESD in People's Hospital of Wuhan University between September 2010 and September 2015 were retrospectively studied.Results Among 45 patients,post endoscopic submucosal dissection electrocoagulation syndrome (PEECS) was developed in 32 cases (22％).The median age in PEECS group was higher (t =-5.783,P =0.000),the median lesion size was larger(t =-5.590,P =0.000),the median length of hospital stay was longer (t =-6.841,P =0.000) than those in non-PEECS group.Univariate regression analysis showed PEECS was associated with the age,lesion size,lesion location,length of hospital stay,malignant tumor,polyps type,resection modality.Multivariable logistic regression analysis showed that the independent risk factors for the development of electrocoagulation syndrome were age ＞65 year (OR =1.123,95％ CI:1.013-1.244,P =0.027),lesion size ＞ 3.5 cm (OR =1.173,95％ CI:1.015-1.357,P =0.031),malignant tumor (OR =3.498,95 ％ CI:1.460-8.379,P =0.005),hospital stay ＞ 10 d (OR =2.480,95％ CI:1.346-4.569,P =0.004),non-rectal lesions (OR =12.612,95％ CI:3.446-46.157,P =0.000).Conclusion Attention should be paid for colorectal lesion patients with high risk of PEECS,when endoscopic submucosal dissection is performed.

AIM: To evaluate the relationship between uPA and NF-?B p65 expression and its clinical significance in breast cancer. METHODS: The uPA mRNA was measured by real-time fluorescent quantitative PCR in 46 cases of breast cancer tissues and their adjacent counterparts. NF-?B p65 were measured using immunohistochemistry. RESULTS: The expression of uPA gene was elevated in 63% of cases, and there was a strong correlation between NF-?B p65 and uPA expression (r=0.451,P

Objective To learn the management staff and funds allocation of the NRCMS in Guangxi,and come up with solution accordingly.Methods Collection of the annual report data of NRCMS in Guangxi from 2009 to 2012,and calculation of the management personnel and funds expenditure.Results The management personnel of NRCMS in Guangxi is found with a 1000-person gap between the actual staffing and approved staffing quota; the management funds rise year by year which come mostly from fiscal appropriation.Yet it accounts for less than 2.00％ and with a high rate of surplus; per-capita funds for management personnel rise significantly,along with their per-capital salaries,yet the highest fall below 25000 yuan per year per person.Conclusion Staffing quota should be fixed more rationally to ensure the number and competence of NRCMS management staff; more funds and better use of management funds are required.

Aim To investigate the effect of Shuanghuanglian on the the load of hepatic HCMV DNA in mice infected with HCMV.Method The model of mice hepatitis infected with HCMV was prepared. 10 days after treated with Shuanghuanlian,the hepatic HCMV DNA was detected qualitatively by polymerase chain reaction;the level of alanine aminotransferase (ALT) and aspartate aminotransferase(AST) in serum were assayed by spectrophotometer;and hepatic pathology was observed with HE staining.Results HCMV DNA load in infected model group was 3875.4760 copies/mg,while in high and middling dosage shuanghuanglian therapy group it was 8.3261 copies/mg、9.1476 copies/mg respectively;It decreased significantly compared with the former(P0.05);low dosage of shuanghuanglian(HCMV DNA load was 3812.8980 copies/mg) had no notable difference compared with infected model group;serum transaminase (ALT,AST) levels significantly elevated in infected model group; serum transaminase level decreased sharply and liver histological pathology was lighten after treated with high and middling dosage of Shuanghuanglian(P

0.05).?2-MG mass concentration was significantly increased in the cerebrospinal fluid(P

OBJECTIVE To surveillance invasive fungal infection rate in SICU,in order to direct intervention to prevent invasive fungal infection.METHODS The samples collected from SICU patients in our hospital between Jan 2003-Nov 2008 were cultured.RESULTS According to the diagnosis standard of nosocomial infections,75 case of 3699 patients were isolated fungi.During 6-years invasive fungal infection rate is 2.027%,(1.05%-2.63%).Totally 86 fungi strains were isolated,the majority of them being Candida albicans,accounting for 46.51%;Candida glabrata 22.09%;Candida tropicalis 13.95%.CONCLUSIONS During 6-years,invasive fungal infection rate and incidence density do not increase.Candida are the major pathogens of fungal infections in SICU.

Objective To understand the performance of the basic medical security system in Guangxi for decision-making support on the development planning of the system during the 12th FiveYear Plan in Guangxi.Methods Descriptive statistics were made to analyze the annual report data of Guangxi's basic medical security system during 2009 to 2011,regarding the basic medical security for urban workers and that for urban residents,as well as those of the new rural cooperative medical system.Results The survey found that the three basic medical security systems in Guangxi have almost achieved full coverage; the compensation ratio keeps rising as the inpatient expenses of urban residents was up to 62.21％,64.96％ and 66.96％ respectively from 2009 to 2011,and that for urban residents up to 34.26％,39.96％ and 49.68％ respectively; the ratio for those covered by the new rural cooperative medical system has been maintained at 45％ for the three years; the coverage of the systems keeps expanding.Conclusion Recommend to integrate pilots of the three security systems and carry out serious diseases pilot programs; encourage reform of the payment system at institutions at or above county level; reform the risk-pooling of disease management of at primary medical institutions; strengthen the information systems of basic medical insurance system,in an effort to ensure the sound development of the basic medical insurance system.
