Comparative medicine is a new crossing frontier branch subject based on laboratory animal science,and the content,aim and request of its research have been remarkably different from that of laboratory animal science.Acting as the methods,means and support conditions of advancment and development of medicine research,comparative medicine is an important platform ensuring the sustainable development of medicine,and is imperative for the medico to be educated with systemic comparative medicine.

AIM:To study whether or not Huangshao Yinxue Granula(HYG) has the therapeutic effect on experimental psoriasis. METHODS: The mice were treated with HYG 3.125,6.25,12.5,and 25 g/kg(i.g.) for 1 or 2 weeks.We studied the effects of HYG on mitosis in mice vagina epithelium,the formation of granular layer in scale epidermis of mice tails,the changes in CD3, CD4 and CD8 factors of the serum in psoriasis-like mice and guinea-pigs. RESULTS: HYG could inhibit the mitosis in mice vagina epithelium,promote the formation of granular layer in scale epidermis of mice tails.It could also diminish the value of serum CD4/CD8 of mice to regulate abnormal immune reaction.HYG had evident therapeutic effect on the ear skin damaged with 5% propanolol in psoriasis-like guinea-pigs. CONCLUSION: HYG has therapeutic effect on psoriasis-like animal models.

Orally disintegrating tablets (ODT), a kind of new solid tablet that rapidly disintegrates to work in the mouth, has became the hot form of new drug research in recent years with many advantages, such as the convenient taking, a widely applicable people, fast acting, high bioavailability, good compliance, and so on. ODT has been widely used in chemical medicines, while the application of it in traditional Chinese medicines (TCMs) is still in the stage of development The development of TCMs ODT provides a new direction for the research of Chinese medicine new dosage, accelerates the pace of connecting to the world and modernization of Chinese medicine. This dosage has a broad market prospect, and its quality control and assessment standards, taste, the disintegration time in vitro and evaluation method are the key factors that affect the industrialization, standardization of Chinese medicine ODT. Therefore, this paper reviewed the characteristics, preparation, taste masking technology and quality evaluation with new technology of ODT. Meantime, numerous application examples of ODT used in traditional Chinese medicine were described. We expect to provide the reference and utilization for the development of traditional Chinese medicine orally disinteeratine tablets.

Objective To investigate the relevant risk factors for fungal infection following operation of the gastrointestinal neo- plasm and offer supporting data for the prevention of fungal infection.Methods Medical records from 116 patients who under- went the operation of gastrointestinal neoplasm in the special group of this hospital from January 2006 to June 2006 were retro- spectively reviewed on the relevant risk factors by univariate and multivariate Logistic regression analysis.Results Of the 116 patients reviewed, 18 had fungal infection.Forty-six samples were positive for fungal pathogen.The most frequently isolated fungal strain was Candida albicans (15/20) and the most common infection site was gastrointestinal tract (14/18).Fungal in- fection after the operation of gastrointestinal neoplasm was significantly relevant with the duration of antibiotic use, duration of post-operative fasting, low serum albumin, high blood glucose and complication of bacterial infection.The duration of antibiotic use was a significantly independent risk factor.Conclusions Reasonable antibiotic use, nutritional support, early enteral nutri- tion and control of blood glucose should be taken into account after the operation of gastrointestinal neoplasm in order to prevent fungal infections.

Objective To investigate the protective effect of basic fibroblast growth factor(bFGF) gene modified mesenchymal stem cells(MSCs-bFGF)on cerebral isehemia in rats.Methods MSCs or MSCs-bFGF were transplanted into rat models of focal cerebral ischemia by intravenous injection.The neurological deficits and infarction volumes were evaluated,and the survival rate and differentiation of grafted MSCs were observed by double immunofiuoreseent labeling.Results In the rat cerebral ischemic model, both MSCs and MSCs-bFGF showed protective effect on the rats in comparison with control group.However, the protective effect was more significant in MSCs-bFGF group.Double immunofluorescent staining showed the number of BrdU-labeled and NeuN co-expression cells in MSCs-bFGF treated animals(127.40?7.43 and 11.20?3.09)were much more than in those of MSCs treated animals.While there was no significant difference between MSCs-bFGF and MSCs group in the number of GFAP co-expression cells.Conclusion MSCs transplantation has protective effect on cerebral ischemia in rats.Basic fibroblast growth factor gene modified MSCs is more effective than MSCs in neuroproteetion.

Objective To summarize the experience of multidisciplinary consultation for prenatal fetal deformity, and to explore the mode suitable for China. Methods The Obstetrics and Gynecology Hospital of Fudan University and Children's Hospital of Fudan University established a joint multidisciplinary consultation center, including obstetrics, pediatrics, pediatric surgery, ultrasound and other departments. A total of 3 378 pregnant women visited the consultation center from July 31, 2003 to August 1, 2013. After consultation, treatment was divided into three classes:pregnancy termination, pregnancy continuation and perinatal treatment. Follow-up was made through correspondence and telephone communication. Retrospective analysis on reasons for consultation, fetal structural abnormalities of the classification system, chronological order of abnormalities, gestational weeks of diagnosis, maternal-related factors, treatment and prognosis was performed. Results (1) Reasons for consultation:Among 3 378 women undertaking prenatal multidisciplinary consultation, 3 243 (96.00%) were due to fetal factors, and 135 (4.00%) were due to maternal factors. (2) Classification of fetal structural abnormalities:Among the 3 243 cases undertaking consultation with fetal factors, fetal abnormality was found in 80.85%(2 622/3 243). The most common were neurological abnormalities(23.19%, 608/2 622), followed by urinary tract malformation (20.25%, 531/2 622) and cardiovascular malformation (15.48%, 406/2 622). These were followed by digestive system malformation, limb deformities and space-occupying lesions. There were 156 cases of multiple malformations. (3) Average gestational weeks for diagnosis of fetal deformity:The 2 622 cases of fetal deformity were diagnosed at a mean (26.7± 2.1) of gestational weeks (21.1–30.4 weeks). Urinary tract malformations were detected at (24.0±0.7) weeks, whereas digestive system malformations were detected at (28.3±2.6) weeks. (4) Induced labor:Induced labor cases accounted for 35.66% (935/2 622), among which, 92 cases were fetal intrauterine death and 843 cases were active choice. The several highest induced labor rates resulted from multiple malformations (75.64%, 118/156), abdominal wall defects (62.22%, 28/45), diaphragmatic hernia (61.54%, 24/39), cleft lip and palate (55.32%, 26/47) and cardiovascular malformations (49.51%, 201/406). For nervous system (27.80%, 169/608), urinary tract (25.80%, 137/531) and digestive system malformations (26.94%, 66/245), induced labor rates were <30%. For abdominal lesions (14.04%, 25/178) and sacrococcygeal teratoma (13.64%, 3/22), induced labor rates were<15%. (5) Continuation of pregnancy in 1 687 cases:Cesarean section was conducted in 1 046(61.94%). Neonatal death occurred in 117(6.94%).(6) Perinatal treatment:Twenty-one cases were treated during pregnancy, including thirteen cases with fetal ascites and hydrothorax treated by drainage, five cases with fetal anemia treated by intrauterine transfusion and three cases with fetal tachycardia treated by digoxin. Ten cases were treated by ex-utero intrapartum treatment. After birth, 297 newborns immediately underwent neonatal surgery. Among these, 259 cases underwent radical surgery, eleven palliative surgery, and sixteen elective surgery after follow-up. Conclusions Prenatal multidisciplinary consultation can make comprehensive multidisciplinary assessment of fetal prognosis and improve the diagnosis and treatment of structural malformations.

Objective　To explore the relationship between te lomerase activity and bile duct carcinoma and its significance in clinical diag nosis. Methods　Telomerase activities were examined in 23 cases of bile duct carcinoma, 5 cases of carcinoma adjacent tissues and 5 cases of nor mal bile duct tissues respectively with telomerase PCR-ELISA method. Results　Telomerase activity was detected in 18 of 23 cases (78.3%) of b ile duct carcinoma, and was not found in 5 cases of carcinoma adjacent tissues a nd 5 cases of normal bile duct tissues. The detection rate of telomerase activit y had no correlation with patients' age, sex, tumor site and size but significan tly correlated to metastasis of tumor (P<0.05). Conclusion　The level of telomerase activity was significantly higher in bile duct carcino ma and may be served as one of the clinical marker for malignant neoplasm becaus e of its spsecificity.
