Surgery is one of the most important treatments for breast cancer. A part of the early breast cancer patients demand further oncoplastic breast surgery to reconstruct or restore the breast cosmosis after conventional breast conserving surgery, by oncoplastic breast surgery, which is a modern conception and technique including volume dis-placement and volume replacement. Oncoplastic breast surgery using pedicled omental flap is a new approach among volume replacement techniques. It has made some progress in recently years. A systematic review was therefore con-ducted to analyze and illuminate the present status.

Objective: To study the application of CT and MRI fusion technique in the diagnosis and treatment of intraocular and orbital tumors. Methods: 2D-images of 13 patients with intraocular and orbital tumors were fused by special-point registration and Iterative Local Closest Point(ILCP) method; 3D-fusion images were reconstructed by Ray Tracing method. Results: A 3D-CT-MRI fusion images of intraocular and orbital tumors were reconstructed and displayed. The CT and MRI data of intraocular and orbital tumors were displayed on the same image as a comprehensive whole,which provided a stereogram of 3D-structure of the normal and abnormal orbital tissues. Anatomical structure of the orbit was clearly visualized by 3D-CT-MRI image. Conclusion: The multi-modality fusion technique can provide more accurate and comprehensive information for clinical diagnosis of intraocular and orbital tumors, which is helpful for doctors' planning of surgical operations,clinical education and doctor-patient communication.

To discuss the value of the diagnosis and treatment for the submucous myomas by hysteroscope. According to the data of hysteroscopic resection in the treatment of submucous fibroids, the authors suggested that the submucous myomas should be divided into four types and the detailed appearance of each type were discussed. Conclusions: Four types of the submucous myomas were distinguished and the surgical treatment of each type were chosen correspondingly under hysteroscope.

OBJECTIVETo investigate the effect of Actinidia chinensis Planch polysaccharide (ACPS) on the growth and apoptosis of human gastric cancer SGC-7901 cells, and to explore the effect of SGC-7901 cells on p-p38 expression.

METHODSThe inhibition rates at different concentrations of ACPS on SGC-7901 cells at 24, 48, and 72 h were detected using CCK-8 method. Apoptosis ratios in SGC-7901 were determined by flow cytometry after 48-h treatment of different concentrations of ACPS. The expression of pro-caspase-9, PARP, and p-p38 in SGC-7901 cells after treated by different concentrations of ACPS was detected using Western blot. The expression of pro-caspase-9, PARP, and p-p38 was detected after SGC-7901 cells were pre-treated by p38 specific inhibitor.

RESULTSCompared with the control group, the optical density of SGC-7901 cells decreased after treated by 1, 2.5, 5, and 10 mg/mL ACPS (P < 0.05). Meanwhile, the longer the acting time, the lower the optic density (P < 0.01). IC50 was 7.43 mg/mL at 24 h; 3.88 mg/mL at 48 h, and 1.32 mg/mL at 72 h respectively. ACPS suppressed the protein expression of pro-caspase-9 (P < 0.01) and up-regulated the expression of PARP (89KD) (both P < 0.01). Further study showed that the protein expression of p-p38 was up-regulated in SGC-7901 cells treated by ACPS of different concentrations at 24 h (P < 0.05). The expression of phosphorylation p38 and the ACPS induced apoptosis of SGC-7901 cells could be inhibited after treated by specific inhibitor for 2 h.

CONCLUSIONSACPS could inhibit the growth of SGC-7901 cells and induce apoptosis. The underlying mechanism of inducing apoptosis was partially due to activating the p38MAPK path and further activating Caspase9 and PARP, finally leading to cell death.

Generally, P-wave is the wave of low-frequency and low-amplitude, and it could be affected by baseline drift, electromyography (EMG) interference and other noises easily. Not every heart beat contains the P-wave, and it is also a major problem to determine the P-wave exist or not in a heart beat. In order to solve the limitation of suiting the diverse morphological P-wave using wavelet-amplitude-transform algorithm and the limitation of selecting the pseudo-P-wave sample using the wavelet transform and neural network, we presented new P-wave detecting method based on wave-amplitude threshold and using the multi-feature as the input of neural networks. Firstly, we removed the noise of ECG through the wavelet transform, then determined the position of the candidate P-wave by calculating modulus maxima of the wavelet transform, and then determine the P-wave exist or not by wave-amplitude threshold method initially. Finally we determined whether the P-wave existed or not by the neural networks. The method is validated based on the QT database which is supplied with manual labels made by physicians. We compared the detection effect of ECG P-waves, which was obtained with the method developed in the study, with the algorithm of wavelet threshold value and the method based on "wavelet-amplitude-slope", and verified the feasibility of the proposed algorithm. The detected ECG signal, which is recorded in the hospital ECG division, was consistent with the doctor's labels. Furthermore, after detecting the 13 sets of ECG which were 15 min long, the detection rate for the correct P-wave is 99.911%.

Thin endometrium is an important factor influencing the in vitro fertilization and embryo transfer, and there is a lack of effective therapy in the treatment of thin endometrium.The aim of this study was to explore a stable animal model of effective thin endometrium, and to promote the research on thin endometrium pathogenesis and provide experimen-tal basis of treatment.To analyze a variety of establishments of endometrial damage animal model reported in the domestic and foreign literatures,it is concluded that perfusing 95% ethanol into uterine cavities of rats can establish a rat model of thin endometrium,and put forward some experience and methods for its improvement.

BACKGROUND:The incidence of complications folowing conventional repairing for the ruptured tendon is up to 73%, such as delayed healing, adhesion, secondary rupture. These complications severely affect ankle joint function of the patients. OBJECTIVE:To reduce the complications folowing the repair and investigate the role of hernia repair materials in the repairing of ruptured Achiles tendon. METHODS:Eleven patients who underwent repair of ruptured Achiles tendon were retrospectively studied. Among them there were eight males and three females with the mean age of 42 years (26-58 years). Three cases were injured in left side and eight cases were in right side; four cases were open injury by sickle-induced damage and seven cases were closed injury by exercise-induced damage. The hernia repair materials after pruning was applied with a “wrap” method to strengthen the anastomosis repair of Achiles tendon after the conventional repair surgery had been completed. At the time of folow-up, al patients were observed for postoperative local appearance and function recovery, and assessed with Arner Lindholm standards. RESULTS AND CONCLUSION:The folow-up interval was 6-45 months (average 24.5 months). Two cases were lost to folow-up. According to the Arner Lindholm standards, the effects were excelent in seven cases (78%) and good in two cases (22%). Local appearance and function recovered wel postoperatively, and no complications occurred such as wound infection, secondary rupture and so on. A “wrap” method with hernia repair materials is suggested to strengthen the anastomosis repair of ruptured Achiles tendon after the conventional repair surgery is completed, it can significantly promote the healing of Achiles tendon ruptured end anastomosis, prevent Achiles tendon recurrent ruptures, local adhesion and infection.
