Objective To evaluate the surgical technique and procedures of transumbilieal breast augmentation with an inverse U-shape incision and insertion of saline-filled breast implants. Methods With specialized instruments, the subcutaneous tunnel was undermined to the inframammary crease after inverse U incision made along the umbilical border. The subpectoral space was dissected with a dissector after the advancement of obturator across the inframammary crease. The expander was inserted into the subpectoral pocket to be filled to obtain the high degree of symmetry of the breasts. Finally, the previous-ly prepared implants were inserted after the expander deflated and removed. Results All patients gained satisfactory results with no complications, such as hematoma, infection, implant deflation and Baker Ⅲ or Ⅳ capsular contracture. Conclusions Breast augmentation could be performed through umbilical inci-sion with the usage of saline-filled breast implant. This is an alternative of incisions in breast augmenta-tion.

Objective To evaluate the therapeutic effect of autologous fat grafting in secondary cleft lip.Methods Grafting of autologous fat granules was applied to correct lip under-capacity.The technique was used in 40 patients with secondary cleft lip from June 2011 to December 2015.The ratios between the point of upper lip peak to vermilion height and to white lip height on the affected side were measured by Photoshop CS6.Results Satisfactory results were achieved with all 40 patients;the lip contour and morphology improved.The preoperative ratio was 0.417±0.190 and the postoperative ratio was 0.499±0.197, which increased average 26.02%, with statistically significant (P<0.05).Conclusions Autologous fat grafting to correct lip under-capacity with secondary cleft lip is a safe, effective and micro-invasive method which can be sustained over a lengthy period.

Objective To explore the effect of bergamots volatile oil on relieving cough,asthma and eliminating phlegm in asthmatic rats and guinea-pig.Methods Bergamot essential oil was extracted by steam distillation,and the experimental guinea-pigs and mice were divi-ded into 3 groups with high,moderate and low doses of bergamot essential oil respectively(1.080,0.540,0.108 g?kg-1for guinea pig,1.753,0.877,0.175 g?kg-1 for mice).The other group were pre-treated with normal saline as model control group,and animals were fed with acute-brochisis-syrup,aminophylline,and xianzhuli oral-liquid as positive drug control groups.After the medication,the guinea pigs were sprayed with citric acid or histamine in a confined glass to induce cough or asthma,while the latent period of cough or asthma attack was detected.The mice were injected phenol red solution through the abdominal cavity,and the tracheal phenol red secretion volume was measured.Results The latent period of cough in high,moderate and low dose of bergamot volatile oil groups and acute-brochisis-syrup group were significantly longer than that of the model control group(Pa

Objective To investigate the clinical efficacy of combined use of calcineurin inhibitor in the treatment of lupus nephritis in induction or maintenance,which is resistant to mycophenolate mofetil.Methods Sixty-six cases of children with lupus nephritis were selected from February 2014 to September 2016 in Huazhong University of Science and Technology,Tongji Medical College Affiliated Wuhan Children's Hospital.The randomized method was used to divide them into the control group and the observation group randomly.Among them,31 cases in the control group were given glucocorticoid,cyclophosphamide combined with traditional medicine for treatment;35 cases in observation group were given glucocorticoid,mycophenolate mofetil,tacrolimus (calcine phosphatase inhibitor) multi-target therapy for treatment.The clinical effect of 2 groups before and after treatment were compared,and the incidence of adverse reactions in the treatment of 2 groups of children were compared.Results After treatment,the levels of systemic lupus erythematosus disease activity index (SLEDAI),serum creatinine and 24 h urine protein [(6.05 ± 1.04) scores,(45.08 ± 18.52) μmol/L,(0.96 ±0.30) g/L] in the observation group were lower than those in the control group [(11.09 ±2.33) scores,(95.33 ±36.74) μmol/L,(2.05 ±0.74) g/L],and the differences were statistically significant (t =3.097,3.356,3.871,all P ＜ 0.05).Serum complement C3,plasma albumin levels [(1.05 ± 0.28) g/L,(63.24 ± 12.98) g/L] were higher than those in the control group [(0.34 ±0.10) g/L,(35.45 ±6.74) g/L],and the differences were statistically significant (t =4.124,3.567,all P ＜ 0.05).After treatment,the levels of serum complement C3 and plasma albumin were significantly higher between 2 groups than those before treatment,the differences were statistically significant (all P ＜ 0.05).The incidence of adverse reaction (14.29％,5/35 cases) in the observation group was lower than that in the control group (38.71％,12/31 cases),and the difference was statistically significant (x2 =5.128,P ＜ 0.05).Conclusion Multi-target combination therapy and traditional cyclophosphamide therapy can effectively control lupus nephritis in children,but the clinical effect of multi-target combination therapy is better and the adverse reaction is less.

The cephalic dystocia education is an important part of obstetric education. According to current educational environment, the teaching method of multimedia combined with problem-based learning is conducive to resolving the dilemma of dystocia education. Dystocia education is designed to follow the cases as the main line and the problem as a guide, with the full integration of theory and practice. This teaching model has been recognized by the majority of foreign students, and it is worth recommending.

To cultivate applied capability of bioengineering students, five aspects should be done: optimization of experiment teaching system, reformation of experiment teaching mode, intensifying management of experiment teaching, increase of new experiments related tightly to scientific research, and training students’ self-study capability.

Objective To evaluate the feasibility and diagnostic accuracy of CE-MRA with low dose contrast agent by comparison with DSA in diabetic patients with peripheral arterial diseases. Methods ( 1 )Study in vitro: test tubes containing Gd-DTPA of different concentrations were scanned, and the relationship between signal intensities and concentrations of GD-DTPA was analyzed. DSA and CE-MRA with selected concentrations of Gd-DTPA were performed on stenotic vascular models to estimate the proper low dose of GD-DTPA for clinical applications. (2) Clinical applications: 78 diabetic patients with peripheral arterial diseases were scanned from the abdomen and pelvis station to the calf-foot station in a 3 T MR system with standard bolus chase 3D CE-MRA sequence after injection of 13 ml GD-DTPA . The image quality,diagnostic rate of stenosis of arteries in calf and degree of venous contamination were evaluated with Fisher's exact test. DSA images of 220 vascular segments in 22 patients ( 10 segments per patient) were acquired as the gold standard and compared with CE-MRA by using Kappa test. Results The MR signal intensities were proportional to the concentrations of contrast agent in present study, and all stenotic segments of vascular model were displayed by CE-MRA with GD-DTPA at lower concentration of 1.5 mmol/L. As for MRA images of 78 diabetic patients with low dose Gd-DTPA, about 97.4% (76/78) showed diagnostic image quality for pelvic and thigh stations. But the MRA images of lower extremities were interfered by the venous contamination significantly (P ＜ 0.01 ). Compared with DSA for 22 patients, the diagnostic sensitivity, specificity and agreement coefficient (Kappa value) of MRA were 96. 0% ( 168/175), 73.3%(33/45), and 0.72 (P＜0.01), respectively. Conclusion Using 3.0 T MR scanner, high quality CE-MRA of lower limb arteries can be obtained for clinical applications with contrast agent dose as low as 13 ml,which has comparable diagnostic sensitivity and specificity with DSA. But the limitation of venous contamination in MRA image should be resolved in further studies.
