1.Pay more attention to the role of macrophages in chronic low-grade inflammatory diseases
Chinese Journal of Endocrinology and Metabolism 2011;27(3):189-192
It is well known that the macrophages play an important defensive role in the innate immune system. During recent years, with the introduction of the concept of chronic low-grade inflammatory diseases and their further intensive study, the activation and balance of macrophage, as well as its inflammatory effects in chronic lowgrade inflammatory diseases, such as obesity, type 2 diabetes, atherosclerosis, and non-alcoholic fatty liver, are gradually becoming a hot topic of current research. The present article mainly gives an overview of the important role played by macrophages in the inflammatory effects in these diseases.
2.Clinical characteristics of pelvic reconstruction using biomaterial patch in females
Chinese Journal of Tissue Engineering Research 2010;14(16):2949-2952
BACKGROUND: With wide application of biotechnological substitute materials, pelvic repair and reconstruction develop to a certain degree. Biomaterial patch is a major substitute for repairing injured pelvic fascia tissue, so it is widely used for pelvic reconstruction.OBJECTIVE: To investigate the feasibility, efficacy, and clinical value of biomaterial patch to pelvic reconstruction in the females.METHODS: Articles related to pelvic functional disorder, pelvic reconstruction, and application of patch implant were retrieved from PubMed (http://www.ncbi.nlm.nih.gov/PubMed) and (http://www.wanfangdata.com.cn) with the key words of "reconstruction of whole pelvic floor, mesh, synthetic mesh implants" in both Chinese and English between 1990 and 2008. Duplication studies were excluded. A total of 54 articles were initially retrieved, and 17 ones were included in the final analysis.RESULTS AND CONCLUSION:Pelvic organ prohpse, which was a major symptom of pelvic disorder in the females, caused by defect of pelvic supporting structure, injury, and functional disorder. Traditional operation could not solve fundamental question.At present, substitute materials for pelvic repair and reconstruction mainly include biomaterial patch (self-substitute materials, homogeneity substitute materials, and heterogeneity substitute materials) and artificial patch. All of them could substitute the injured pelvic fascia tissue; therefore, they were major substitute materials of pelvic tissue and widely used for pelvic reconstruction. Patch which was used for pelvic reconstruction realized the recovery of anatomic structure and caused functional recovery, with simple and easy processing. Additionally, patch application did not prolong operative time and cause complication, but induced well tolerance, security and reliability, and remarkable short-term effect on patients. However, the long-term efficacy should be further studied. The modified pelvic reconstruction is clinically valuable for patients with varying prolapsed sites.

Acta Anatomica Sinica 1955;0(03):-
The position,length,size,and the site and pattern of ramification of the innominate arteries and common carotid arteries were studied in 76 specimens(♂44,♀32)of one- year-old to three-year-old Chinese infants. 1.The position relation between the innominate artery and trachea may be divided into three patterns:type Ⅰ:2 infants(2.63?1.8%),type Ⅱ:33 infants(43.42? 5.72%),type Ⅲ:41 infants(53.95?5.71%). 2.In 76 specimens the ramification region of innominate arteries of the Chinese infants were studied,among which in 57 specimens(75.0?4.96%)the site of ramifi- cation of innominate arteries is situated above the upper border of the sternoclavicular joint,and in 19 specimens(25.0?4.96%)behind the sternoclavicular joint.The region of ramification is higher in position in the infant than in the adult. 3.The average length of innominate arteries of all 76 specimens of 3 age groups: one,two,and three years old,is 20.7?0.42mm,19.2?0.56mm and 21.8?0.94mm respectively.The average circumference is 19.8?0.64mm,20.3?0.21mm and 21.0? 0.51mm respectively. 4.In 63 cases(82.9?4.32%)the innominate artery arises from the aortic arch by itself,in the other 13(17.1?4.32%)it arises from a common trunk,which is formed by the union of the innominate artery with the left common carotid artery.Among the 76 specimens,71 cases did not give off branches on its way,but in 4 specimens(5.26? 2.56%)the thyroidea ima is branched off directly from the innominate artery on its way,while in 1 specimen(1.32?1.31%)it arises from the common trunk. 5.The average site of ramification of the common carotid artery of the 76 Chinese infants is situated at the level of npper border of the intervertebral disc between the third and the fourth cervical vertebrae,but it is different on both sides:37 cases(48.7? 5.73%)with a higher level on the left,14 cases(18.4?4.44%)with.a higher level on the right side,25 cases(32.9?5.38%)with both sides on the same level. 6.The ramification angle of the common carotid arteries of the 76 infants fall into three patterns:60 sides(39.5?3.96%)belong to the acute angle pattern,40 sides(26.3? 3.57%)belong to the arcform pattern and 52 sides(34.2?84%)belong to the in- termediate pattern.The acute angle pattern is more common than the arcform pattern in the infants. 7.The average length of common carotid arteries of all 76 specimens of the three age-groups in one-、two-、three-year-old Chinese infants was 42.9?1.55mm,45.7?0.57 mm and 47.8?1.50mm on the right side and 59.0?1.10 mm,56.7?2.99mm and 64.9?1.62mm on the left side respectively,but the average circumference was 14.8 ?0.77mm,16.3?0.14mm and 16.6?0.19mm on the right side and 15.6?0.61 mm, 16.6?0.13mm and 17.3?0.40mm on the left side respectively.
4.STUDIES OF THE AORTIC ARCH AND ITS RAMIFICATIONS IN THE CHINESE INFANTS
Acta Anatomica Sinica 1957;0(04):-
The aortic arch and its ramifications were studied in 76 chinese infant specimens (♂44,♀52)We examined its position,length and circumference and the types of its ramifications. 1.In average,the superior border of infant's aortic arch is situated at the level of the intervertebral disc between the second and third thoracic vertebrae,and the inferior border is situated at the level of the upper one-third of the fourth thoracic vertebra. 2.The medial point between the superior and inferior borders of the aortic arch,in average,is situated at the level of lower one third of the third thoracic vertebra.In the 3 age-groups,1,2 and 3-year old infants,in 76 specimens,we found that the levels of the medial point of aortic arches,corresponding to 6.05,6.10and 6.19 in the 7 th region of the vertebral column respectively,Comparison of this figures with those of the adult revealed that its height in the infant is higher than in the adult. 3.The average lengths of aortic arch of the 3 age-groups of the Chinese infants were 20.6?1.31mm,19.3?0.59mm and 20.8?0.43mm respectively. 4.The circumferences of the aortic arch of the 3 age-groups of the Chinese infants before the aortic arch divided int?the innominate artery,in average,were 35.8?0.86 mm,36.4?1.04 mm and 38.6?0.83 mm respectively,and after dividing into the left subclavian artery,in average,they were 26.1?1.01mm,26.9?1.25 mm and 29.7?0.79 mm respectively. 5.Seven types can be distinguished in the patterns of the ramifications of the aortic arch.One type was not included in the twenty types of the ramification that have been suggested by Chang Wei-lung according to McDdonald and Anson's classification.This new type increases the number of the types of the human aortic arch to twenty one.The seven types viz: Type A:52.infants,68.42?5.33%.Type B:11 infants,14.47?4.03%.Type G: 4 infants,5.26?2.56%.Type D:1 infant,1.32?1.31%.Type F:4 infants,5.26? 2.56%.(One of the four cases is named thyro-thymus trunk).Type BF:1 infant,1.32 ?1.31%.(This type was composed of a common trunk,which consisted of the inno- minate and left common carotid,the left subclavian and the thyroidea ima arising from the common trunk.According to De Garis's classification,we combine type B with type F into type BF).Type J:3 infants,3.95?2.23%.(This type was more common in infants than in adults). 6.By comparing the types of ramification of aortic arch in 76 specimens with those of the adult,it reveals that the types of the ramifications of aortic arches vary with age.
5.Association between cholesteryl ester transfer protein-TaqIB polymorphism and coronary heart disease
Chinese Journal of Postgraduates of Medicine 2009;32(34):1-5
Objective To determine the frequency of the cholesteryl ester transfer protein (CETP)-TaqIB polymorphism and investigate its relationship with plasma lipid levels and coronary hert disease(CHD). Methods Two hundred and thirty-eight patients with CHD (CHD group) and 203 age-matched controls( control group) were selected, the CETp-TaqIB mutation was detected by restriction fragment length polymorphism of the CETP gene. Results In the total subjects, the frequency of B1 and B2 alleles were 59.4%(262/441 ) and 40.6%( 179/441 ) respectively. Compared with that in control group, the frequency of CETP genotype BIBI was higher in CHD group [39.9%(95/238) vs 29.6% ( 60/203 ), P<0.05], and the frequency of B1B2 was lower in CHD group [44.1%(105/238) vs 53.7%(109/203), P< 0.05]. Compared with that in the B2 homozygotes, high density lipoprotein cholesterol (HDL-C) and apolipoprotein (apo)A I level were significantly lower in the B1 homozygotes [(1.19±0.36) mmol/L vs (1.38±0.39) retool/L,( 1.17±0.33 ) g/L vs ( 1.30±0.31 ) g/L, P<0.05]. The B 1 homozygotes was associated with higher degree of cononary stenosis than the B2 carriers (P<0.05 ). There was no significant association between CETP-TaqIB genotype and the risk of CHD (P=0.147). Conclusions CETP-TaqIB polymorphism affects the concentrations of lipaproteins. There are significant associations between the B1 homozygotes and lowerHDL-C and apo A I levels. The B1 allele is not an independent risk factor for CHD.

International Journal of Surgery 2009;36(4):255-258
Restenosis after interventional treatment is the major factor infheneing the result of percutaneous transluminal angioplasty, and it is a hot and difficult research in recent years. Endothelial progenitor cells are a class of proliferation and able to differentiate into vascular endothelial precursor cells, and take part in the repair and angiogenesis after endothelial injury-intimate. It is expected to play an important role in the prevention of vascular restenosis after interventional treatment. In this article, we reviewed the endothelial progenitor cell research overview and advances of prevention of restenosis after interventional therapy in recent years.
7.Position and application of proteomics in induced differentiation of bone mesenchymal stem cells
Chinese Journal of Tissue Engineering Research 2010;14(14):2623-2626
BACKGROUND:The essence of cell differentiation is a selectively intra-cellular gene expression,which results in specific proteinic synthesis and causes changes in biochemistry,structure and function.Thus,original proteomics and a single protein analysis can not meet the requirement in study.Proteomics technology provides a powerful tool due to the large scale,systemical study of protein transformation and interaction,which can be used for exploring molecular mechanism of bone mesenchymal stem cells(BMSCs)during directional differentiation.OBJECTIVE:To introduce proteomics,to summarize the research of proteomics in directional differentiation of BMSCs,and to forecast the development of proteomics research methods.METHODS:To search articles highly related with BMSCs,cell differentiation,and proteomics published on CNKI (www.cnki.net/index.htm),Sciencedirect(http://www.Sciencedirect.com),I.S.I(http://www.isiwebofknowledge.com)were searched,and the key achievements were included in the analysis.RESULTS AND CONCLUSION:A total of 29 documents were reviewed,and the experiences in the application of proteomics technology in the directional differentiation of BMSCs were summarized.With the innovation and development in methodology and technology,proteomics will become a powerful tool for us to study the potential mechanisms of BMSCs directional differentiation.
8.The mechanism of AmpC β-lactamase change from inducible type to constitutive type
Fudan University Journal of Medical Sciences 2010;37(2):189-193
Objective To investigate the influence of plasmid spread and ampD mutation to Enterobacter cloacae that leads to the AmpC β-lactamase change from inducible type to constitutive type. Methods The Enterobacter cloacae were isolated from the patients with nosocomial infection. The inducible type isolations and their constitutive type changers were put into the same group. The plasmid ampC gene and chromatin ampD gene in pairs in each group were amplified, sequenced and compared. Results Of 195 patients infected by Enterobacter cloacae of inducible type, 25 (12.82%) were changed to the ones of constitutive high type. In these 25 changed groups, 10 were caused by plasmid spread, 10 by ampD mutation, 1 by both, and 4 by neither. Twelve changed constitutive type strains had ampD significant mutations, in which 7 were frame-shift mutations and 5 were spot mutations. Conclusions The change ratio of Enterobacter cloacae from inducible type to constitutive type is rather high. Both plasmid spread and ampD mutation are possibly the mechanism of such change. Plasmid mediated AmpC β-lactamase spreads among different species and interregionally. The mutation rate of chromatin ampD gene is also higher than the natural mutation rate. These two mechanisms should be considered in clinical treatment.

10.Application of the two-paths double U-shaped fixer in the intravenous indwelling needle
Chinese Journal of Practical Nursing 2016;32(29):2281-2284
Objective To study the application of the two-paths double U-shaped fixer in clinical intravenous indwelling needle fixation. Methods A total of 420 cases using of intravenous indwelling needle from January to June 2015 were involved and divided into experimental group(210 cases) and control group(210 cases) by random digits table method. The two-paths double U-shaped fixer was applied in experimental group and the control group were used tape by Y type to fix. The incidence of returning-blood, blocking, phlebitis, slippage and the comfort between two groups were observed and compared. Results The incidence of returning-blood, blocking, phlebitis, slippage in experimental group were 6.2%(13/210), 0.5%(1/210), 0 , which were lower than those in control group 48.6%(102/210), 5.7%(12/210), 1.4%(3/210) seperately, the differences were statistically significant (χ2=117.895, P<0.01). The incidence of phlebitis levelⅠ,Ⅱ,ⅢandⅣin experimental group were 3.3%(7/210), 1.4%(3/210), 0.9%(2/210), 0, which were lower than those in control group 11.9%(25/210), 9.0%(19/210), 3.8%(8/210), 2.4%(5/210), the differences were statistically significant(Z=-5.960, P<0.01). The incidence of the comfort level 1, 2, 3 and 4 in experimental group were 92.4%(194/210), 6.2%(13/210), 1.4%(3/210), 0 individually, which were higher than those in control group 36.7%(77/210), 46.7%(98/210), 12.4%(26/210), 4.3%(9/210), the differences were statistical significant (Z=-16.228, P < 0.01). Conclusions Two-paths double U-shaped fixationis is better than Y-shaped tape fixation. To compare the venous indwelling needle fixation, two-paths double U-shaped fixer could fix more effectively and safety. At the same time, it also has advantages in convenient, observation and appearance. It could be widely used in clinical practice.
