OBJECTIVETo investigate the clinical application of pedicled superficial circumflex iliac artery (SCIA) flaps in Burns and Plastic Surgery.
METHODS19 cases with skin and soft tissue defects were repaired with the Superficial circumflex iliac artery flaps. The defects located in the hand and forearm, the lower abdomen and perineal area, the radicle area of thigh, etc. Before the SCIA flaps were transfered to the recipient areas, 15 cases with different kinds of wounds were debrided thoroughly, 3 cases with scar were removed directly. The size of the flaps ranged from 3.0 cm x 4.5 cm to 26.0 cm x 22.0 cm, and the pedical was 5 cm to 7 cm in length.
RESULTSThe flaps in the 18 cases survived completely. Skin necrosis in the distal end of the flap appeared in 1 case, and the wound healed after the second repair. The follow-up period rang from 3 to 18 months. The apperance and function of the hand or foot was satisfactory.
CONCLUSIONSBecause the pedicled SCIA flaps can be obtain conveniently and contain sufficient blood-supply, so the flap is easy to survive and the flap can be designed in a large size. We believe it is an ideal method to use this flap to repair skin and soft tissue defects located in hands, forearms, the lower abdomen and perineal areas, the radicle area of thigh and so on.

Objective To approach a way to induce MSCs to dopaminergic neuron by mesencephalic conditional media and cytokines in vitro,and supply an ideal cells source for the treatment of Parkinson's disease.Methods The rat MSCs were isolated primarily from the femurs and tibias of the Wistar rats.MSCs were cultured,proliferated and purified by passage culture.Cultuered MSCs were divided into the control and the experimental group.In control group,MSCs were cultured without any induction medium.MSCs of experimental group were first cultured at medium containing bFGF for 24 hours.Then media were replaced with induction media which contained the agents as follows,respectively:GM_1,GDNF, GDNF+GM_1,GDNF+GM_1+mesencephalic conditional media.The surface markers of the differentiated neuron,such as NSE and TH were detected by immunocytoehemistry after MSCs were cultured in induction media for 3 and 7 days.Results In control groups,the NSE expression of MSCs was very lower than experimental groups.The percentage of NSE-positive cells of GDNF+GM_1+mesencephalic conditional media group in 7 day((45.257?5.999)/HP)was significantly more than other groups(control group is 2.214?0.779,GM_1 group is 22.014?3.624,GDNF group is 31.345?2.850,GDNF?GM_1 group is 40.314?4.203,P
7. Effects of red ginseng saponin components on neurochemicals in rat plasma
Chinese Traditional and Herbal Drugs 2017;48(14):2918-2924
Objective To investigate the effects of red ginseng saponin components A and B on 15 neurochemicals in rat plasma. Methods Saponin components A and B were prepared from red ginseng total saponin by macroporous adsorption resin. The composition and contents of saponin components A and B were detected using UPLC-Q-TOF-MS/MS method. A total of 15 kinds of neurochemical substances such as dopamine (DA), adrenaline (E), norepinephrine (NE), serotonin (5-HT), 5-hydroxytryptamine (5-hydroxytryptamine), tyrosine (Tyr), glycine (Gly), glutamic acid (Glu), glutamine (Gln), aspartic acid (Asp), taurine (Tau), serine (Ser), tryptophan (Try), acetylcholine (Ach), and histamine (His) were measured by high performance liquid chromatography- mass spectrometry (UPLC-QQQ-MS/MS). Results By analyzing the intrinsic relationship between saponin composition and amount of neurochemicals, it was found that components A and B had significant differences in saponin composition, and the larger polar saponins were mainly concentrated in component A. The polar of saponin contained in B is relatively small. The levels of Ach, Tau, Glu, Gln, Asp, Tyr, E, NE, and DA in rat plasma of each dose group were increased, and the plasma levels of Gly, His, 5-HT, Ser, HIAA, and Try were significantly increased and positively correlated with the dose, suggesting that the larger polar saponins could increase the excitatory neurochemical content and the smaller saponin fraction inhibitory neurochemicals. Conclusion Red ginseng has a moderating effect on the content of central nervous system. The content of smaller polar saponins is related to the maintenance of brain activity, improvement of memory function, prevention of brain fatigue, maintenance of awakening and nervous system of anti-aging, while the larger polar saponin fraction is associated with the regulation of psychiatric rhythm, reduction of stress response and improvement of sleeping.

Objective Aggressive fibromatosis is a rare kind of soft tissue tumor and was evaluated by few large studies. This study was to evaluate the clinical characteristics and identify the prognostic factors of this disease. Methods One hundred and forty-two patients with aggressive fibromatosis treated from January 1983 to August 2009 in Tianjin Medical University Cancer Hospital were retrospectively reviewed.The prognostic value of clinical and treatment factors was analyzed. Univariate analysis was performed with Log-rank test and Multivariate analysis was performed with Cox regression model. Results The follow-up rate is 93.7% and the median follow up time was 54 months (range,6 -208 months). Sixty-three patients had a minimum follow up time of 5 years and 6 patients had a minimum follow up time of 10 years. The male/female ratio was 1/1.84. The disease was most popular in women aged from 18 to 35 years old. The disease frequently occurred in the trunk (55.6%) and extremity (31.7%). All patients received surgery,and 46 received radiotherapy. The 5-year and 10-year local recurrence rates were 24. 4% and 31.1%,respectively. The 5-year and 10-year overall survival rates were both 99. 3%. Univariate analysis revealed that factors correlated with local recurrence were tumor size ( χ2 = 4. 37, P = 0. 037 ) and margin status (χ2 = 12. 36,P =0. 002). Multivariate analysis revealed that margin status was an independent risk factor (RR = 2. 219; χ2 = 9. 47,P = 0. 002) and radiotherapy was an independent protective factor ( RR = 0. 360;χ2 = 4. 95, P = 0. 026 ) for disease recurrence. When radiotherapy was delivered, the 10-year local recurrence rate decreased from 70. 1% to 20. 7% in patients with positive margin ( χ2 = 4. 22, P = 0. 040 )and decreased from 19.8% to 10.4% (χ2= 0.90, P= 0.344) in patients with negative margin.Conclusions Radical resection is the mainstay of treatment for aggressive fibromatosis. Postoperative radiotherapy can reduce the recurrent rate for patients with positive margin. In patients with negative margin,the role of radiotherapy should to be further evaluated in large clinical trials.

Objective:To investigate the inhibitory effects of halofuginone on radiation-induced pulmonary injury and to explore the therapeutic mechanism of this drug. Methods:A total of 72 healthy female C57BL/6 mice were randomized into 4 groups, namely, control, irradiation, halofuginone, and irradiation plus halofuginone groups, with 18 mice in each group. No treatment was performed in the control group. In the halofuginone group, the halofuginone lavage was conducted once a day, with a continuous course treatment for a month or until sacrifice of the mice. In the therapeutic alliance group, the treatment mode was the same as that in the halofuginone group. Then, a 6MV-X ray single fraction irradiation was performed after the completion of a 15-day intragastric administration. At 24 h, 1 week, 2 weeks, 4 weeks, 12 weeks, and 20 weeks after the irradiation, 3 mice from each group were randomly sacrificed, and total lung tissues were harvested. The lung was dissected to prepare pathological sections. The sections were stained with hematoxylin and eosin staining (H&E) to explore morphologic changes. The protein and mRNA expression levels of TGF-β1 were analyzed by a combi-nation of immunohistochemistry and polymerase chain reaction. The level of hydroxyproline was also measured. Results: The out-comes of H&E staining showed that halofuginone markedly ameliorated the acute pulmonary inflammation and fibrosis induced by irra-diation. The combination group had a lower level of hydroxyproline than the irradiation group, with statistically significant differences at 20 weeks after irradiation (P=0.037). The protein and mRNA expression levels of TGF-β1 were higher in the irradiation and combi-nation groups than in the control group and (or) halofuginone group at different time points (P<0.05). The combination group had lower TGF-β1 protein expression than the irradiation group at different time points, with statistically significant differences at 2, 4, 12, and 20 weeks after the irradiation (P<0.05). Meanwhile, TGF-β1 mRNA level was lower in the combination group than in the irradiation group only at 4 and 12 weeks after the irradiation (P<0.05). Conclusion:Halofuginone can ameliorate the irradiation-induced lung inflamma-tion and fibrosis probably by inhibiting the radiation-induced TGF-β1 expression. Therefore, halofugione is expected to be a therapeu-tic drug for preventing irradiation injury of the lung.
