The mechanism of osteogenesis inducted by SW and its effect of bone repairing are explained emphatically. Besides, the development prospects of SW in healing human disease are described and is indicated that SW will maybe a clinical method for osteoporosis and other disease in orthopedics according to its osteogenetic mechanism.

Objective: To study the absorption and transportation of euphobiasteroid in Caco-2 cell monolayer model. Methods: Caco-2 cell monolayer model was used to study the process of bi-direction transport of euphobiasteroid, and the effects of time, drug concentration, and inhibitors on the process were investigated. The concentration of euphobiasteroid was detected by UPLC-MS/MS, and the apparent permeability coefficient (Papp) and apparent permeability (PDR) were calculated. Results: During the transport process of euphobiasteroid in Caco-2 cells, the Papp values of variety concentration were from 1 × 10-6 to 1 × 10-5. The cumulative transshipment volume was increased with time and concentration, which presented concentration-dependent manner. The PDR values of 10, 30, and 50 μmol/L euphobiasteroid were 1.35, 0.83, and 0.65, respectively. Verapamil hydrochloride could promote the transportation of euphobiasteroid from AP side to BL side. Conclusion: The absorption of euphobiasteroid in intestine is moderate and mainly through passive transport. There may be excretion mechanism of intestinal transport protein in the intestine absorption of euphobiasteroid.

Objective To study the clinical and pathologic features,histological criteria and pathologic factors contributing to diagnosis of mixed epithelial and mesenchymal tumors(mixed m?llerian tumors,MMT)of the uterus.Methods A retrospective study of 102 cases of MMT of the uterus (74 adenofibromas including 9 recurrent cases,3 atypical polypoid adenomyomas,2 carcinofibromas,10 adenosareomas and 13 carcinosarcomas)was undertaken.Clinical records,gross features and tissue slices were reviewed.The follow-up data were analysed.Results The most common symptom was vaginal bleeding.Clinical signs included pelvic mass,uterine polyps,and enlarged uterus.Benign MMT usually presented as exophytic polypoid masses extending into the uterine cavity or protruding through the external os,often broad-based,lobulated and papillary.It was hard to distinguish low-grade malignant MMT from the benign ones by gross appearance.High-grade malignant MMT had the common gross features of carcinoma and sarcoma.Histologically,MMT showed a biphasic differentiation of mesenchymal and epithelial components.MMT were classified according to whether these elements were benign or malignant.Nine cases of adenofibroma without unique features for the diagnosis of adenosarcoma recurred at postoperative intervals of 3 to 96 months.Recurrent tumors were almost always confined to the original site.Conclusions Uterine MMT tumors according to WHO diagnostic criteria are not rare.The differential diagnosis depends on a multifactorial analysis.The recurrent adenofibromas may be a kind of borderline tumors with benign appearances and malignant behavior.

Objective To study on the relationship between psychological harmony and mental health of health care providers. Methods Surveys on psychological harmony and mental health were conducted in 313 health care providers in Heibei Province by psychological harmony and SCL-90 questionnaire. Results The general psychological harmony,and mental health level of health care providers is lower than the national level; The psychological harmony and its dimensionality of health care providers is affected mainly by many factors such as emotional stability, the level of patients' cooperation, on-duty situation in holiday time, salary, the rate of solving difficult miscellaneous diseases, the number of medical tangle and paranoid symptoms.etc., among which solving difficult miscellaneous diseases effectively is the most important factor. Conclusion The general psychological harmony situation does not affect health care providers' mental health.

Objective To observe protective and repairing effect of Aorui Gel on esophageal mucosa injury in reflux esophagitis rats. Methods Rat models of reflux esophagitis were established by partial pylori ligation plus cardiomyotomy. Model control group,low-,middle-and high-dose Aorui Gel groups,positive control group,excipient control group and sham operation group were set up. Rats were treated with the corresponding drugs 7 days after operation. After treatment for 14 days,the rats'general state,and macroscopic features and pathological features of esophageal mucosa were compared. Results Macroscopic features and pathological features of esophageal mucosa in Aorui Gel groups differed from those in the model control group,inflammation of esophageal mucosa in Aorui Gel groups was alleviated,and pathological features were relieved and arrived to the normal state. Conclusion Aorui Gel can alleviate esophageal mucosa injury in reflux esophagitis rats,indicating that Aorui Gel has protective and repairing effect on esophageal mucosa injury.

Objective To investigate the gamma (γ) passing rates for volumetric-modulated arc therapy (VMAT) dosimetric verification with different techniques.Methods A total of 12 VMAT plans for the treatment of different anatomical sites in cancer patients were chosen.The Octavius 4D system was used to measure the dose distributions in two different settings:the gantry was rotating (three-dimensional (3D) and 2D γ-analysis) and the gantry was fixed at 0°(2D γ-analysis).The γ passing rates were analyzed with 3%/3 mm and 2%/2 mm criteria, using the paired t test or Wilcoxon signed-rank test.The 2D γ passing rates for different irradiation methods were calculated.Results For the 3D and 2D dose distributions obtained at a rotating gantry angle as well as the 2D dose distribution obtained at zero gantry angle, the average γ passing rates were 96.03%, 96.98%, and 98.90% for 3%/3 mm (P=0.227, P=0.000, P=0.003);82.08%, 84.04%, and 90.90% for 2%/2 mm (P=0.379, P=0.000, P=0.000).For the 2D dose distributions obtained with different irradiation methods, the average γ passing rate was 98.99% for 3%/3 mm and 93.68% for 2%/2 mm.Conclusions The VMAT dosimetric verification based on a 3D volumetric dosimeter at a rotating gantry position can be clinically useful for delivery quality assurance (QA), and can achieve the most reliable dose calculation for VMAT, which has more referential values.
