BACKGROUND:As meniscectomy may result in various adverse reactions, tissue-engineered meniscus is expected to be used for meniscus repair. Seed cel selection and optimal physicochemical stimuli are crucial for the construction of tissue-engineered meniscus.
OBJECTIVE:To overview the seed cel s for the tissue-engineered meniscus construction and the research progress of physicochemical factors.
METHODS:The first author retrieved the CNKI and Medline databases using the keywords of“meniscus, tissue engineering, seed cel s, physical and chemical factors”in English and Chinese, respectively, to retrieve articles related to the seed cel s and physicochemical factors of the tissue-engineered meniscus construction. Irrelative and repetitive articles were excluded, and 49 eligible articles were enrol ed for analysis.
RESULTS AND CONCLUSION:The seed cel s must maintain their phenotype and synthetic ability after physicochemical stimulation in combination with scaffolds, to achieve the reproducibility of tissue-engineered meniscus. Most of cytokines can be used for promoting the proliferation and differentiation of chondrocytes, but the underlying mechanisms were little known. Their application in the meniscus tissue engineering needs to be studied in depth. Currently it is urgent to improve physicochemical stimuli in order to construct the tissue-engineered meniscus. The shear force does harm to chondrocyte phenotype, and dynamic compression loading has been proved to enhance Ca+and glycosaminoglycan release. The fibrous cartilage stimulated by shear force and other factors may be helpful for constructing the tissue-engineered meniscus. An elaborated randomized control ed trial and the long-term quantitative analysis are of importance to assess the research results.

Objective To summarize the sonographic features of fetal limb deformity. Methods Systematic continuous sequence approach (SCSA) was performed with two-dimensional and three-dimensional ultrasonography(USG) in 28 383 fetuses to observe the fetal limb development, posture abnormality and other accompanied malformations. Compared with the pathological and radiological findings, the characteristics of fetal limb deformity on USG were summarized. Results Among 28 383 fetuses prenatal ultrasound detected 207 cases of fetal malformations (0.7%, 207/28 383) including 29 cases of limb deformities (14%, 29/207). In the 29 cases, there were osteogenesis imperfecta in 2 cases, syndactyly in 1 case, cleft hand deformities in 1 case, uncifom hand in 1 case, clubfoot deformity in 12 cases, cleft foot in 1 case, micromelia in 4 cases, limb body wall complex in 1 case, forearm defect in 2 cases, and radius absence in 4 cases. Chromosome karyotype analysis was conducted in 7/29 cases, of which 6 cases were normal and 1 case was trisomy-13 with syndactyly. In addition, the fetal limb deformities were found at 17-19 weeks of gestation in 4 cases, at 20-24 weeks in 23 cases, and at 25-33 weeks in 2 cases. In summary, 27/29 cases were identiifed at 17-24 weeks of gestation. Conclusions Prenatal ultrasound is the ifrst-choice method for screening of fetal limb deformity. The detection rate of limb deformity could be greatly improved by using SCSA method with the supplement of 3D ultrasound.

PurposeThere is a certain correlation between parameters of CT perfusion imaging and pathological type and angiogenesis in lung cancer, in order to discuss the value of CT perfusion imaging parameters such as blood volume (BV), blood flow (BF), time to peak (TTP) and peak enhancement image (PEI) for prognosis, this study is designed to observe the relationship between the parameters of CT perfusion imaging and micro lymphovascular density (MLVD) in non-small cell lung cancer (NSCLC).Materials and Methods 100 patients were enrolled in the study, all of them underwent CT perfusion imaging and 60 were diagnosed NSCLC by pathology, immunohistochemical staining was performed to determine the expressions of MLVD of the 60 NSCLC, and the correlation analyses were carried out to determine the relationship between CT perfusion imaging and MLVD.Results The expression of MLVD was the most in the peripheral tissue of cancer (25.16±1.28), the next in the cancer tissue (16.38±3.58), and the least in the normal lung tissue (7.56±4.38), the difference was statistically significant (P<0.05). There was positive correlation between MLVD with BF and BV of the tumor (r=0.643 and 0.598, P<0.01).Conclusion Some parameters of CT perfusion imaging are correlated with MLVD, the invasion and metastasis in lung carcinoma can be predicted to some extent according to this correlation. Parameters of CT perfusion imaging such as BF and BV are correlated with MLVD in patients with NSCLC, thus can be used to predict the invasion and metastasis of lung cancer.

Objective To retrospectively analyze medical data of patients with colorectal cancer (CRC) so as to provide evidence for clinical use of opportunistic screening.Methods A total of 2450 CRC patients (male 1377,female 1073) who were treated at five hospitals in North China during October 2001 and September 2011 and had complete medical records and pathological results were recruited.The correlations of incidenceofCRCwithage,gender,tumorlocationandhistologicaltypeswere analyzed.Results Of all the CRC patients,those less than 50 years old accounted for 18.14％ ; and the incidence of CRC was substantially increased in those over 50 years old.Seventy-three percent of tumor occurred at the rectum and sigmoid colon,6％ at descending colon,7％ at transverse colon and 14％ at ascending colon.Moderately,well or poorly differentiated adenocarcinoma accounted for 50.33％,40.35％and 9.32％,respectively.Histological differentiation was not correlated with age and gender ( P ＞ 0.05 ).Conclusions Age and gender should not be considered a determination of opportunistic screening for CRC.Colonoscopy is recommended as an alternative CRC screening procedure.

Objective To study the influence of Ginkgo Leaf Extract and Dipyridamole Injection to urinary albumin (U - Alb) in 24 hours in diabetic nephropathy. Methods 37 patients with diabetic nephropathy were involved in the study. They were divided into test group(20 patients) and control group(17 patients). The test group was grouped into group A(pristine diabetic nephropathy) and group B (clinical diabetic nephropathy) according to urinary albumin. The control group was grouped into group A (pristine diabetic nephropathy) and group B(clinical diabetic nephropathy) according to urinary albumin. The test group was injected Ginkgo Leaf Extract and Dipyridamole Injection 20?g from vein ,one time a day, 14 day continuously ,but control group without Ginkgo Leaf Extract and Dipyridamole Injection. All patients were treated with same blood glucose, blood pressure, plasma lipids, and others. Results After the treatment of two groups, the level of the urinary albumin deceased obviously as compared with before treatment, and deceased significantly as compared with control group. Conclusion Ginkgo Leaf Extract and Dipyridamole Injection can lower urinary albumin in patients with diabetic nephropathy.

Objective To investigate the relationship of the expression of vascular endothelial growth factor (VEGF)and the mi-crovessel density (MVD)with multi-slice spiral CT perfusion imaging.Methods 80 patients with solitary pulmonary nodules under-went perfusion scan by 16-slice spiral CT.Among them,45 diagnosed as lung cancer by pathology were enrolled in the study.After surgery,the slice of the pecimen was selected similar to the corresponding slice of CT images,and the immunohistochemical staining was performed to determine the expression of VEGF and the MVD.Spearman correlation analysis was used to determine the rela-tionship of expression of VEGF and the MVD with CT perfusion parameters.Results There was more expression of VEGF and the MVD in NSCLC.There were positive correlations between VEGF,MVD and BF (both P<0.05).The peak enhancement image (PEI)and TTP have significant correlations with MVD (P<0.05).Conclusion Some parameters of lung CT perfusion imaging are correlated with MVD and VEGF.

Human acute premyeloid leukemia cell cDNA expression library was constructed to screen acute premyeloid leukemia tumor antigen. Total RNA and purified mRNA were extracted from human premyeloid cell line NB4. First and second strands of cDNA were synthesized by reverse transcription. After blunting, the cDNA fragments were ligated with EcoR I adapters. Then the cDNAs were digested with Xho I, and less than 400 bp cDNA fragment was removed by Sephacryl-S400 spin column, the remaining were ligated with lambdaZAP vector. The recombinants were packaged in vitro, and a small portion of packaged phage was used to infect E. coli XL1-Blue-MRF' for titration. The recombinants were examined by color selection. In order to evaluate the size of cDNA inserts and the diversity of library, the pBK-CMV phagemid was excised from the ZAP express vector by using ExAssist helper phage with XLOLR strain, and then the pBK-CMV phagemid was digested by Xho I and EcoR I. The results showed that the NB4 cell line cDNA library consisting of 1.65 x 10(6) recombinant bacteriophages was constructed with the recombinant ratio of 99.6%. The average length of the recombinant exogenous inserts was about 1.7 kb. It was concluded that the constructed cDNA library are deserved to screen target clones.
