Objective To explore the feasibility and cosmetic results of video-assisted subcutaneous mastectomy and immediate reconstruction. Methods Two patients who suffered from breast diseases and need to excise the breasts received a video-assisted total subcutaneous mastectomy and immediate reconstruction in our center. Results Both patients felt satisfied on the cosmetic result. According to the operative experience of these two patents combined with review, the key point of the operation was summarized as follows. The incisions on the anterior axillary line were small and concealing. External retraction method was used to establish the working space. Video-assisted operation was combined with euthyphoria. Blunt dissection was combined with electrical surgery unit and ultrasound knife to isolate the breast skin flap. After breast glandectomy was completed, silica gel prosthesis was put into the interspace behind ectopectoralis. Pressure dressing for 3 weeks was done to prevent the prosthesis upward displacement. Conclusion The video-assisted subcutaneous mastectomy and immediate reconstruction is a safe and feasible operation method with the better cosmetic result.

Objective To investigate the efficacy of tertiary liver transplantation.Methods The clinical data of 4 patients with hepatobiliary disease who were admitted to the General Hospital of Chinese People's Armed Police Forces from April 2002 to December 2012 were retrospectively analyzed.All the patients received orthotopic liver transplantation,and received tacrolimus + mycophenolate mofetil (MMF) + hormone after operation.All the patients were followed up till May 2014,and their prognosis was learned.The measurement data were analyzed using the t test.Results Three patients with benign hepatic disease received tertiary liver transplantation due to biliary complications and chronic rejection,and 1 patient with hepatic cancer received tertiary liver transplantation because of hepatic cancer recurrence.The average interval between the primary and secondary liver transplantation was 16.0 months,which was shorter than 22.5 months of the interval between the secondary and tertiary liver transplantation.The mean operation time in the secondary liver transplantation was (11.4 ± 1.0)hours,which was significantly shorter than (14.1 ± 2.2) hours in the tertiary liver transplantation (t =3.644,P ＜ 0.05).The median volumes of blood loss in the secondary and tertiary liver transplantation were 1 300 mL and 1 800 mL,and the median volumes of blood transfusion were 1 400 mL and 3 100 mL.The hepatic function of the 4 patients recovered smoothly at the early time after liver transplantation.Two patients (3 cases) were complicated with infection postoperatively (1 patient was infected by pseudomonas aeruginosa within 30 days after liver transplantation,and was cured by active antimicrobial treatment),and they were cured after anti-infectional treatment.One patient died of hepatic failure at the 80th month after the primary liver transplantation,1 died of hepatic cancer recurrence complicated by pulmonary,bone and retroperitoneal lymph node metastasis at the 107th month after the primary liver transplantation,and the other 2 patients survived for 104 months and 26 months after the primary liver transplantation,respectively.Conclusion Tertiary liver transplantation is effective for the treatment of biliary complications and chronic rejection after liver transplantation,and it can extend the life span of patients with hepatic cancer recurrence if there are insufficient donor resources.

OBJECTIVETo explore the therapeutic effect of diagnosis and treatment program of integrative medicine (IM) on level 2 hypertension in the young and middle-aged patients and their ambulatory blood pressure.

METHODSA randomized, placebo parallel and controlled, multi-center clinical trial was performed. Totally 199 young and middle-aged level 2 hypertension patients were randomly assigned to the treatment group (99 cases) and the control group (100 cases). All received combined hypotensive treatment program by taking Nifedipine Sustained Release Tablet and Hydrochlorothiazide as basic drugs. Patients in the treatment group additionally took Western medicine (WM) combined Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily), while those in the control group additionally took WM combined simulative agents of Jiangyabao serial drugs (0.31 g per tablet, 2 tablets each time, twice daily). The treatment course was 8 weeks for all, and 24-week follow-ups performed. 24 h ambulatory blood pressure and casual blood pressure, and their efficacies were compared between the two groups, and safety assessed as well.

RESULTSCompared with before treatment in the same group, daytime and night casual blood pressure, as well as 24 h ambulatory blood pressure were all obviously improved in the two groups (P < 0.01). Average diastolic and systolic blood pressures at night decreased more in the treatment group than in the control group with statistical difference (P < 0.05). There was no statistical difference in total efficacies of daytime casual blood pressure or ambulatory blood pressure (P > 0.05).

CONCLUSIONJiangyabao serial drugs combined WM in treating young and middle-aged level 2 hypertension patients showed obvious effect in improving night blood pressure, especially for night diastolic blood pressure.

Objective To explore the application and significance of multiple clinical pathway training oriented teaching model in clinical teaching of laboratory diagnostic. Methods Totally 50 medical students enrolled in the Second Military Medical University from September to December in 2015 were divided into experimental group and control group. The course consists of theoretical teaching and experi-mental operation. The pathway group (n=25) were introduced into multiple clinical pathway training oriented teaching method. The theoretical teaching was carried out bysimulation examination application, simulation interpretation and simulation diagnosis and treatment, while the experimental course was carried out by using video teaching combined with actual operation. The control group was taught by traditional teaching method using slide teaching and operation display. The theoretical test including case study and operational skill tests were performed among students in both groups after 10 class hours training . The satisfaction questionnaires were conducted to evaluate the effectiveness and satisfaction of teaching guided by clinical pathway. Differences were compared with independent sample t testing using GraphPad Prism 5.0 statistical software. Results The medical records about professional theoretical test including case study and opera-tional skill test in the pathway group were superior to those in the control group with significant statistical difference (both P<0.05). The records of medical students were (81.84±7.21), (42.00±2.79) in the pathway group and (76.24 ±6.98), (37.00 ±3.71) in the control group. The questionnaire result showed that the pathway group's satisfaction was high, especially with the theoretical knowledge andsceneteaching (higher than 80％). The pathway group believed that multiple clinical pathway training helped to improve learning interest and clinical thinking ability . Conclusions Multiple clinical pathway training oriented teaching model is helpful for the medical students to achieve the basic idea of clinical pathway, improve the profes-sional ability, enhance the interest of learning and the quality of teaching, standardize teaching and promote teaching and learning.

While the near infrared spectroscopy (NIRS) is used to measure the inhomogeneous samples with diffuse reflection mode, the accuracy and robustness of the calibration model is not quite good for the variation of spectrum scattering and absorption coefficient in those samples.Therefore, an establishment strategy of hybrid model based on homogeneous sample and calibration transfer method was proposed to solve the problem of detection inhomogeneous samples by NIRS.This work was focused on the tobacco leaf samples aspect.Three common calibration transfer methods, including Shenk′s patented algorithm (Shenk′s), piecewise direct standardization (PDS) and calibration transfer based on canonical correlation analysis (CTCCA), were used to construct two hybrid models of tobacco powder mixed with cut tobacco and tobacco powder mixed with tobacco flake samples to predict nicotine content in the samples of cut tobacco and tobacco flake.Experimental results showed that the hybrid model of adding some cut tobacco and tobacco flake samples to the powder model would get preferred prediction ability.Root mean square errors of cut tobacco and tobacco flake samples were reduced by 1.39% and 2.73%, respectively.This showed that the hybrid model was help for the improvement of the predicted results and the robustness of model.Moreover, CTCCA got the optimal performance between these three calibration transfer methods.Therefore, the scheme of building a hybrid model by NIRS homogeneous model and calibration transfer method to determinate the heterogeneous samples is feasible, which can accelerate the development of on-line near infrared spectroscopy technology and will provide reference for the share of near infrared spectral model.
