Chinese Journal of Tissue Engineering Research 2007;0(24):-
BACKGROUND: The repair of soft tissue defect is disturbing plastic surgeons for a long period of time. Each strategy has its own limitation. Adipe authoritative journals were included. Repetitive articles and Meta analysis articles were excluded. Finally 34 articles werose tissue engineering technique provides a novel resolving approach. OBJECTIVE: To analyze the research status of adipose tissue engineering and their defects, and to prospect the possible application in clinic. RETRIEVAL STRATEGY: A computer-based online search of Medline was undertaken to identify articles about adipose tissue construction published in English from January 1991 to July 2007 with the keywords "fat, tissue engineering". Meanwhile, we searched Chinese Journal Full-text Database for the Chinese articles dated from January 1991 to July 2007 with the same keywords in Chinese. 241 English and 101 Chinese articles were collected. The titles and abstracts were firstly read to select the articles about the construction of tissue-engineered adipose tissue, and 276 repetitive studies were excluded. LITERATURE EVALUATION: Sixty-six Chinese and English articles were selected for further analysis, and finally 30 articles were included. DATA SYNTHESIS: Cell types, scaffold, blood supply and microenvironment are factors for constructing tissue-engineered fat. Adipose tissue defect and insufficiency are two obstacles for the plastic surgeons for a long time. Autologous free fat transplantation is a common therapy, but its resorption limits the further application. Tissue engineering is a possible technique to resolve this problem. At present, the tissue-engineered construction of adipose tissue has become a study focus due to the great demand of plastic surgery. CONCLUSION: Graft remaining normal appearance and function for a long period of time can realize the application of tissue-engineered adipose tissue in clinic. Tissue-engineered adipose tissue is promising to resolve the problems like soft tissue defects in clinic.
2.Studies on Relationship of Serum Insulin like Growth Factors and Catch-up Growth in Rats
Chinese Journal of Perinatal Medicine 1998;0(01):-
Objective To investigate relationship of serum insulin like growth factors(IGFs) and catch up growth. Methods The model of rats intrauterine growth retardation (IUGR) was built by clamping bilateral uterine arteries and veins of pregnant rats. The growth parameters (body weight and length), organs weights (brain, lungs and liver) and serum concentrations of IGF Ⅰ, Ⅱ of all neonatal rats was measured at birth and postnatal day 3 and day 5, respectively. Results (1)At birth, the serum levels of IGF Ⅰ, Ⅱ and the average growth parameters, organs weights in IUGR rats were significantly lower than those in control group( P 0.05). The serum of IGF Ⅱ in high catch up group was significantly higher than that at birth( P 0.05). Conclusion Both IGF Ⅰ, Ⅱmay play an important role in the regulation of catch up growth and the decrease of IGF Ⅰ, Ⅱlevels may be the internal factors contributing to the absence of postnatal catch up growth in IUGR rats.

OBJECTIVE:To study sterility test after using Non-PVC bivalve soft-bag injection in PIVAS. METHODS:The test was divided into 3 groups according to the type of transfusion solution packaging and dispensing environment. Group 1 received Glucose solution using bivalve soft-bag,dispensed in PIVAS;group 2 received Glucose solution using bivalve soft-bag,dispensed in wards area;group 3 received Glucose solution using plastic bottle,dispensed in wards area. After puncturing 1,3,6,9 times (n=80),finished products placed in ward for 0,2,4,6 h(n=20),and then sterility test was conducted with membrane filtra-tion method stated in second part of Chinese Pharmacopoeia (2010 edition). Infusion contamination of 3 groups was analyzed at 9th puncture. RESULTS:The growth of bacteria was not found in group 1;the positive detection rate of group 2 and 3 were 2.5%and 3.8%(n=320). The total positive detection rates after puncturing 1,3,6,9 times were 0,0.4%,0.4%,7.5%(n=240);the positive detection rates of group 1 were all 0,those of group 2 were 0,1.25%,0,8.75%and those of group 3 were 0,0,1.25%, 13.75%(n=80). After 9 times of puncture,the positive detection rates of group 1 after placing 0,2,4,6 h were all 0,those of group 2 were 25%,5%,0,5%;those of group 3 were 5%,15%,5%,30%(n=20). CONCLUSIONS:The use of the Non-PVC bi-valve soft-bag injection in PIVAS can effectively prevent microbial contamination.

ObjectiveTo study the efficacy of different doses of tamsulosin hydrochloride sustained release tablets for treatment of premature ejaculation (PE). MethodsEighty PE patients from September 2010 to January 2011 were divided into two groups randomly,the 0.2 mg dose group and the 0.4 mg dose group.The therapeutic effect was assessed by the changes of the patients' CIPE-5 scores.ResultsThe intra-vaginal ejaculation latency time (IELT) of the two groups were (0.98 ± 0.47 ) and ( 0.89 ± 0.47 ) min respectively before treatment,and (4.40 ± 1.86 ) and (6.40 ± 5.10) min respectively after treatment.There were significant differences ( P < 0.01 ).As for satisfaction degree of sexual life,lessening the patients' sexual anxiety and nervousness,and decreasing the difficulty in retarding ejaculation,the group of 0.4 mg had better effect than the other group.ConclusionLarge dose of tamsulosin hydrochloride sustained release tablets could prolong IELT and increase the sexual satisfaction.

Diagnostics is one of the most important bridge courses for medical students from basic to clinical. Doctor-patient communication runs through the whole process of patient diagnosis and treatment. How to improve medical students' ability of doctor-patient communication? Our teaching team has carried out continuous reform and explored the scientific effective teaching mode. Recently, through the construction of "doctor-patient communication skills" quality online course, efforts have made to build an online and offline blended learning mode, which has gradually realize the integration with diagnostics teaching, and has achieved remarkable results. It also provides a scientific practical basis for the integration of doctor-patient communication and other clinical courses, which is worthy of promotion.

Background/Aims:
Colorectal cancer (CRC) is a common malignant tumor, and circular RNAs (circRNAs) are abnormally expressed in CRC. However, the function and underlying mechanism of circRNA pinin (circ-PNN; hsa_circ_0101802) in CRC remain unclear.
Methods:
Exosomes were isolated from the plasma of CRC patients and identified by transmission electron microscopy and Western blotting. The RNA expression levels of circ-PNN, miR-1225-5p, and fibroblast growth factor 13 (FGF13) were measured by quantitative real-time polymerase chain reaction. Cell proliferation was detected by Cell Counting K-8, colony formation, and 5-ethynyl-2’-deoxyuridine assays. Cell apoptosis was assessed by flow cytometry. The expression of apoptosis and metastasis-related proteins was evaluated by Western blotting. The associations among circ-PNN, miR-1225-5p, and FGF13 were confirmed by dual-luciferase report assay and RNA immunoprecipitation assay. A xenograft model was used to verify the function of circ-PNN in tumor formation in vivo.
Results:
circ-PNN expression was upregulated in plasmic exosomes derived from CRC patients. The expression of circ-PNN and FGF13 was upregulated, while miR-1225-5p expression was downregulated in CRC cells incubated with plasmic exosomes derived from CRC patients.Tumor-derived exosomes promoted the proliferation, migration, and invasion but inhibited apoptosis of CRC cells. Moreover, the addition of tumor-derived exosomes partly reversed the inhibitory effect of circ-PNN knockdown on CRC tumor progression in vitro and in vivo. Thus, circ-PNN acts as a sponge for miR-1225-5p to regulate FGF13 expression.
Conclusions
Tumor-derived exosomal circ-PNN promoted CRC progression through the regulation of the miR-1225-5p/FGF13 pathway, providing a potential therapeutic target for CRC.
