Objective To explore relationships between the aesthetical education and the development of students' entire quality in medical school. Methods Taking the Introduction to Medical Aesthetics as the blueprint, we used the multimedia during the whole courses while considering our student's actual needs. Students were given tests and a questionnaire. Results 114 students took the examination, 89.5 % of which achieved the "good" grade, while 10. 5 % of them got the "pass"grade; none of them failed to the test. Conclusion The aesthetical education has taken great impressions on the development of the students' aesthetical quality.

Objective To assess the clinical application value of phleboplasties combined with microvascular anastomotic device in venous anastomosis with diameter discrepancy in head and neck defects reconstruction.Methods Sixty-six pairs of veins with significant diameter discrepancy were anastomosed in head and neck reconstructive surgeries with free flaps.Forty of them were anastomosed with microvascular anastomotic device (the coupler group) after phleboplasties including lateral incision, Y-T enlargement and wedge excision while the other 26 pairs of veins were conventionally sutured (the sutured group).Diameter of each vein, anastomosis time, post-operative vascular crisis, flap survival and complications related to the microvascular anastomotic device were recorded.Results The average anastomosis time of the coupler group was (4.78 ± 1.14) min for lateral incision, (5.16 ± 2.07) min for Y-T enlargement and (11.09 ± 3.21) min for wedge excision, and all of them were significantly shorter than that of the sutured group.In the sutured group, all flaps survived except for 2 veins with poor blood flow were cut and re-anastomosed during the operation;1 flap with venous crisis within 72 hours after the operations was explored and replaced with the pectoralis major myocutaneous flap.All veins in the coupler group were successfully anastomosed in a single coupling procedure without anastomotic impatency, blood leak, vessel tearing and ring shedding.No vascular crisis occurred postoperatively.One patient underwent cervical haematoma 5 hours after the operation, and the flap blood supply was unaffected after the haematoma was removed.All flaps in the coupler group survived completely.Patients in both two groups were followed up 6 to 18 months.All flaps healed perfectly and no obvious surgical complications or microvascular anastomotic device rejection happened.Conclusion When anastomoses are carried out using microvascular anastomotic device between veins of different size, phleboplasties including lateral incision., Y-T enlargement and wedge excision can not only reduce the size discrepancy and the anastomosis time, but also ease the difficulty level and guarantee the patency of the venous anastomoses.Wedge excision enjoys the advantage of haemodynamics, and obstruction of venous reflux hardly occurred for size reduction.It should be considered preferentially when external jugular veins are used as the anastomotic vein of the recipient sites in head and neck reconstruction.

Objective To investigate the management of difficult recipient vessel preparation in microsurgical reconstruction for oral and maxillofacial defects with free flaps and to assess the clinical outcome.Methods A total number of 739 patients with oral and maxillofacial defects underwent consecutive free flap reconstruction with 761 free flaps from May,2012 to May,2015.There were 37 patients who could not find or lack of proper recipient vessels for microvascular anastomosis during operation.Among them,22 were recurrent oral cancer after tumor ablation,10 of them undrewent post-operative radiotherapy;5 were second primary oral cancer,7 diagnosed with osteoradionecrosis,and 3 suffered from oral and maxillofacial defect and deformity caused by trauma or inflammation.Forty free flaps including 23 anterolateral thigh flaps (ALT),10 fibular flaps and 7 radial forearm flaps were harvested.Methods and techniques used during the operation,instant patency rate after anastomosis,the overall survival rate of free flaps,and post-operative complications were recorded.Results Ninety-one anastomoses were performed between 87 pairs of vessels in 37 patients.Fifty recepient vessels were located on ipsilateral side of neck,and the most frequently used recipient vessels were those preserved or not being damaged in former operation and radiation,former transferred free flap vascular pedicles and residual ends of the ligated vessels.Thirty-seven recepient vessels were found on the contralateral side of neck.Thirty-one cases of long-pedicle flap harvesting,2 cases of vein and artery grafting,4 cases of vessel transposition,5 cases of phleboplasties,9 cases of end-to-side anastomoses,and 1 case of flow-through technique were applied in recipient vessels preparation alone or in combination.The patency rate of anastomosis during operation was 100％ and the overall survival rate of free flaps was 97.5％.Conclusion Recurrent oral cancer after tumor ablation,second primary oral cancer,osteoradionecrosis and deformity caused by trauma and inflammation are the main reasons of unsuitable recipient vessel conditions in microsurgical reconstruction for oral and maxillofacial defects.Methods including long-pedicle flap harvesting,venous grafting,vessel transposition,phleboplasty,end-to-side anastomosis and flow-through technique applied alone or in combination are still reliable choices for management of neck difficult recipient vessel preparation and anastomosis.

Objective To investigate the effects of liposome mediated intraocular gene transfection of endostatin on the inhibition of the development of choroidal neovascularization (CNV) in a rat model. Methods Experimental CNV model in Brown Norway rats was induced by laser photocagulation. The recombinant eukaryotic expression plasmid pSecTagA hEndostatin or control plasmid pSecTagA and liposome complexes were injected into the subretinal space of the model rats. In situ hybridization and immunohistochemical observation confirmed the presence of endostatin mRNA and protein expression two weeks after injection. Intraocular and serum levels of endostatin were measured by enzyme linked immunosorbent assay. The intensity of fluorescein leakage from the photocoagulated lesions was studied at 13 d after photocoagulation. The area of CNV was measured using high molecular weight FITC dextran (MW2?10 6) for high resolution angiography in RPE choroid sclera flat mounts. In addition, sections of CNV lesions were studied by light microscopy and endoglin (CD105) immunohistochemical evaluation. Results The retina, RPE, choroidal were infected by subretinal delivery of the pSecTag hEndostatin and expressed the endostatin. Two weeks after intraocular injection, the level of endostatin in the whole eye homogenates were (50 14?3 43) ng/eye and (31 5?2 21) ng/eye, respectively. Fluorescein leakage from the CNV lesions decreased significantly as compared with that in the control groups. The average area of CNV at the sites of the Bruch's membrane rupture showed significant difference in eyes injected with endostatin as compared with that in the control eyes. Endothelial cells demonstrated strong immunoreactivity of CD105 in CNV lesions in the control eyes. Conclusion Liposome mediated endostatin gene transfection can significantly inhibit the development of CNV.

Objective To investigate the hepatoprotective effect of silybin-phosphatidylcholine complex(SPC) in sepsis rats.Me-(thods) Fifty Wistar immature rats were randomly divided into 3 groups:normal control(10 cases),septic group(30 cases) and interfe-(rence) group(10 cases).In septic group and interference group,rats were treated by cecal ligation and puncture(CLP).Meanwhile,the interference group was given SPC before 2 hours of CLP and after 2 hours of CLP.Blood of rats was taken from all groups to determine the levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1),alanine aminotransferase(ALT) and aspartate aminotransferase(AST) at varying intervals.Results The levels of serum TNF-?,IL-1,ALT and AST after CLP were significantly elevated in septic group compared with the normal control group(P

ObjectiveTo evaluate the efficacy of rehabilitation associated with local intramuscular injection of botulinum toxic A (BTX-A) on spastic cerebral palsy (CP).Methods60 children with spastic CP were divided into experimental group and control group with 30 cases in each group. Cases of experimental group were treated with rehabilitation associated with local intramuscular injection of BTX-A. Cases of control group were treated only with rehabilitation treatment. The therapeutic efficacies of two groups were evaluated with physician rating scale (PRS) and activities of daily living (ADL) evaluation systems.ResultsImprovement of clinical evaluations index-PRS and ADL in experimental group was much more significant than that of control group (P<0.05). ConclusionRehabilitation associated with local intramuscular injection of BTX-A can improve the efficacy of spastic CP.

?AlM: To investigate repeatability and accuracy of a latest Keratograph for evaluating the tear film stability and to compare its measurements with that of traditional examination methods.
?METHODS: The results of noninvasive tear film break-up time ( Nl-BUT ) including the first tear film break-up time ( BUT-f ) and the average tear film break-up time ( BUT - ave ) were measured by Keratograph. The repeatability of the measurements was evaluated by coefficient of variation ( CV ) and intraclass correlation coefficient ( lCC) . Wilcoxon Signed-Rank test was used to compare Nl-BUT with fluorescein tear film break-up time ( FBUT) to confirm the correlation between Nl-BUT and FBUT, Schirmer l test values. Bland-Altman analysis was used to evaluate consistency.
?RESULTS: The study recruited 48 subjects ( 48 eyes ) (mean age 38. 7±15. 2 years). The CV and lCC of BUT-f were respectively 12. 6% and 0. 95, those of BUT-ave were 9. 8% and 0. 96. The value of BUT-f was lower than that of FBUT. The difference had statistical significance ( 6. 16±2. 46s vs 7. 46±1. 92s, P<0. 01). There was significant positive correlation between Nl-BUT and FBUT, Schirmer l test values ( P< 0. 01 ). The scope of 95% limits of agreement (LoA) was 4. 46s in BUT-f and FBUT, while the scope of LoA was 3. 64s in BUT-ave and FBUT.
?CONCLUSlON: Keratograph can provide Nl-BUT data that has a better repeatability and reliability, which has great application prospects in diagnosis and treatment of dry eye and refractive corneal surgery.

OBJECTIVETo discuss the replantation of fingertip amputation in lack of availability of intravenous anastomosis.

METHODSFrom November 2009 to November 2010, 86 patients (104 fingers) with fingertip amputation were treated with replantatioin, including 64 males and 22 females, with an average age of 26 years ranging from 2 to 64 years. The time from injury to therapy was from 30 min to 12 h, time of broken finger ischemia was from 2.5 to 12 h. Preoperative examination showed no obvious abnormalities. Four different replantation methods were selectively applied to these 104 amputated fingertips of 86 cases: (1) replantation with anastomosis of single or bilateral proper digital artery in 37 fingers; (2) replantation with arteriovenous bypass in 27 fingers; (3) replantation with exclusive anastomosis of digital artery in 24 fingers; (4) replantation with removing the palmar pocket method in 16 fingers.

RESULTSOne hundred and two of 104 amputated fingertips were survived. Among these survived fingers,75 cases (92 fingers) were followed-up for 6 to 24 months. According to the assessment standard of Chinese Medical Association of Hand Surgery, the results were excellent in 52 cases, good in 19, poor in 4.

CONCLUSIONIt benefits to expand the indications and improve the survival rate of replantation of fingertip amputation with the correct choice of different replantation methods according to the injury situation of the broken fingertip artery after debridement under the microscope.
