Objective To evaluate therapeutic effect and safety of hysteroscope operation in treating hysteromyoma. Methods 146 patients were subjected to transcervical resection of myoma (TCRM), curative effects were evaluated as satisfaction or dis-satisfaction according to the degree of bleeding control, the rate of growth of myoma and the need of subsequent surgery. Results The total satisfactory rate is 95%. and satisfactory rate of type 0 and Ⅰ reached 100%. There was no complication in all patients. Conclusion TCRM is the best choice in treating submucous myoma. The results of surgery were satisfactory to intramural myoma if gasp the indictions. Selecting proper indications for operation, B ultrasonic monitoring severity are important for ensuring the operation effect and safety.

Objective To investigate the inhibitory effect of maspin gene on metastasis and invasion of gastric cancer and its mechanism.Methods Maspin gene was ligated to the expression vector PCR2.1 with T4 DNA ligase after the PCR2.1 was digested by HindⅢ/XbaⅠ.The recombinant vector maspin/PCR2.1 was transfected into human gastric cancer cell lines MKN28 and SGC7901,then the mRNA and protein expression changes of maspin gene,uPA and uPAR were detected respectively by PT-PCR and Western blotting.Results After identified by digestion and sequencing,the reconstructed plasmid was confirmed to contain the correct and full nucleotide sequence of maspin gene.The expressions of maspin gene were up-regulated in MKN28 and SGC7901 cell lines,while the expressions of uPA and uPAR were down-regulated.Conclusion The expression vector maspin/PCR2.1 is constructed successfully and can be expressed in eukaryotic cells.Expressions of uPA and uPAR can be inhibited by maspin gene.

Objective To discuss the application effect of peer support education in improving theself-management ability of old patients with diabetes. Methods A total of 160 cases of old patients with type 2 diabetes who were treated and hospitalized from June 2014 to August 2015 were selected, then equally divided into observation group and control group through using random number method.Finally, 76 cases were studiedin observation group, while 75 cases in control group. The health education guidance of conventional diabetes had been used in two groups for six months, and the peer support education was also conducted for the patients in observation group on the basis of conventional education. The self-management ability, insulin standard injection knowledge-belief and attitude-behavior/practice (KAP) and glycosylated hemoglobin (HbA1c) value of old patients with diabetes were observed before intervention, 3 months and 6 months later, respectively. Also,the hypoglycemia frequency in two groups was compared during intervention. Results After three months of intervention, the score of diet, exercise management, glucose monitoring, foot care, pharmaceutical administration and smoke for self-management ability in observation group was 4.63 ± 0.92, 4.18 ± 0.97, 2.86 ± 0.96, 2.35 ± 0.59, 4.01 ± 1.43 and 0.62 ± 0.29, respectively, while that of these indicators in control group was 3.69 ± 0.83, 3.52 ± 0.67, 1.75 ± 0.67, 1.63 ± 0.72, 3.05 ± 1.39 and 0.59 ± 0.38. Except smoke (P > 0.05), the differences between two groups were statistically significant (t=2.987-5.965, P < 0.05). After six months of intervention, the score of diet, exercise management, glucose monitoring, foot care, pharmaceutical administration and smoke for self-management ability in observation group was 5.86±0.93, 5.37±0.61, 3.97±0.94, 5.06±0.92, 5.81±0.73 and 0.89 ± 0.31, respectively, while that of these indicators in control group was 3.68 ± 0.96, 3.65 ± 0.95, 1.86 ± 0.88, 2.65±0.88, 3.21±1.13 and 0.81±0.39. The difference was statistically significant (t=9.336-15.633, P<0.01), except smoke (P>0.05). Then, the insulin was normally injected in observation group after six months of intervention, the score of knowledge, attitude and behavior was 5.63 ± 1.87, 43.17 ± 6.03 and 16.57 ± 1.59, while that in control group was 3.76 ± 0.83, 23.71 ± 0.59 and 10.16 ± 0.95. The differences between two groups were statistically significant (t= 8.569, 15.623, 6.751, P<0.01). Also, the level of glycosylated hemoglobin was decreased from (8.17 ± 0.32) % to (7.16 ± 0.41) %, and the difference was statistically significant (t=-3.560, P=0.000). Conclusions Peer support education couldenhance the self-management consciousness of old patients with diabetes, standardize the insulin injection, improve the ability of self-management and improve glucose metabolism index so that it is worthy of being clinically popularized and applied.

BACKGROUND:The hip is a complicated structure and irregular in shape. It is hard to measure stress distribution and transmission. OBJECTIVE:To establish a three-dimensional finite element model of the hip joint and upper femur, and analyze the stress distribution and transmission characteristics of the acetabulum region under different loads, and explore mechanics mechanism of hip fracture based on CT data. METHODS:The three-dimensional finite element hip and femur model were reconstructed in Mimics 14.0 based on the CT data of a healthy adult man. After dividing mesh, assigning material and transforming into finite element model, the stress distributions of anterior wal , the top, and the posterior wal of the acetabulum, the stress of acetabulum areas and displacement of acetabular unit were calculated with finite element software Ansys 13.0 software under 300, 600, 900 and 1 200 N. RESULTS AND CONCLUSION:(1) A three-dimensional finite element model of the hip and the femur was successful y established, consisting of 284 183 nodes and 160 665 units. (2) The characteristics of the stress distribution of acetabulum region:the maximal stress was concentrated on the posterosuperior part of acetabular crest, fol owed by the posterior wal and the anterior wal in order in upright position under different loads. The stress transmitted by four ways:from acetabular crest to ilium, along linea terminalis of pelvis to sacroiliac joint, in the acetabular sockets, and along the pubic ramus. The stress and the propagation distance were increasing as the loads increased. Acetabular element stress variable was increased. (3) Above results indicated that three-dimensional finite element model of the human hip joint established by Mimics 14.0 based on CT data matches the anatomical structure in a great degree, could be used in the biomechanics analysis under different loads, and has a guiding significance for design of artificial hip prosthesis.

Yang deficiency syndrome.There were 126 cases with one diseased artery branch(31.1%),135 cases with two diseased artery branches(33.3%),144 cases with three diseased artery branches(35.6%).The blood stasis syndrome and phlegm-turbid syndrome were mainly in those cases with three diseased artery branches,and Qi stagnation syndrome was common in those with one diseased artery branch(P

The purpose of this study is to evaluate the embryotoxicity of alkaloids in Senecionis Scandentis Hebra on in vitro cultured mouse embryos. Mouse whole embryo culture (WEC) was applied in this study. Post-implantation (8.5 d) mouse embryos were isolated from their mothers, and cultured in medium of immediately centrifuged serum (ICS) with different concentrations of seneciphylline (target concentrations were 100, 50, 25 and 12.5 μg x mL(-1)) or senkirkine (target concentrations were 50, 25 and 12.5 μg x mL(-1)) for 48 h. After culturing completed, the development and organic morphodifferentiation of the cultured embryos were evaluated microscopically. Treatment with seneciphylline and senkirkine had adverse effects on the development and organic morphodifferentiation of embryos. The effect also had clear dose-response. Alkaloidals in Senecionis Scandentis Hebra had embryotoxicity on cultured embryos, which indicated that pregnant people exposed to Senecionis Scandentis Hebra may get potential risk on fetus.
