[Objective] To investigate the clinical efficacy of tacalcitol combined Halometasone sequential therapy in the patients of plaque psoriasis. [Methods] 117 cases of plaque psoriasis col ected between 2011.01 and 2013.02 were randomly divided into treatment group and control group. The treatment group were treated with tacalcitol and Halometasone therapy, and required topical use Halometasone(1 time/day) in the morning ,tacalcitol use in the evening(1 time/day) before the first 2 weeks. Continuous two weeks treatment from Monday to Friday with tacalcitol(2 times/day), Saturday and Sunday with Halometasone(2 times/day), final y the transition to be used alone tacalcitol(2 times/day) in the next two weeks of continuous treatment. Control group of pa-tients given alone Halometasone(2 times/day) for 6 consecutive weeks. Observe the adverse reactions PASI scores during and after completion of treatment within the two groups. Al patients were fol owed for three months, observed recurrence. [Results] The PASI score between two groups of patients declined during treatment, especial y at the 4th and 6th week within the treatment group. Both groups had no serious adverse reactions. In treatment group, 54 patients had effective responses, the total effective rate was 90%, significantly better than the control group(41 cases,71.9%). In the fol ow-up of 3 months, the recur-rence rate was 11.1%in the treatment group, significantly lower than the control group(31.6%). The difference of total efficiency and the recurrence rate with-in the two groups was statistical y significant. [Conclusion] Tacalcitol combined Halometasone sequential therapy of plaque psoriasis has significant clinical effi-cacy and low recurrence rate.

Objective: Patients with high-risk breast cancer has a high recurrence rate. The clinical value of high-dose adjuvant chemotherapy supported by autologous HSCT (hematopoietic stem cell transplantation) for postoperative breast cancer patients with high risk of recurrence remains controversial. This study was to explore the efficacy and safety of high-dose adjuvant chemotherapy with paxlitaxel and thiotepa supported by autologous HSCT for postoperative breast cancer patients with high risk of recurrence. Methods: Twenty-four postoperative breast cancer patients (stages II-III) with high risk of recurrence were enrolled in this study. The patients received paclitaxel 175 mg/m2 and G-CSF (granulocyte colony-stimulating factor) 5 μg/kg for mobilization and collection of peripheral blood CD34+ stem cells. Then two cycles of high-dose adjuvant chemotherapy were given subsequently [11 patients: paclitaxel 175 mg/m2 + thiotepa 150 mg/m2 + carboplatin (area under curve = 6; 300 mg/m2 divided in two days); 13 patients: paclitaxel 175 mg/m2 + thiotepa 150 mg/m2) every 28 d]. The CD34+ stem cells were infused for an autologous HSCT on day 2 after chemotherapy, and the G-CSF was started on day 3 after chemotherapy and discontinued until the peripheral WBC (white blood cell) count reached over 10.0×109/L continuously for three days. The adverse effects of high-dose adjuvant chemotherapy were observed. The median DFS (disease-free survival) and the three-year DFS rate were calculated. Results: The median follow-up was 32 months (3-62 months). The median DFS was 32 months. The three-year DFS rate was 56.3%. High-dose chemotherapy had a good safety profile and no treatment-related death. Conclusion: High-dose chemotherapy with paclitaxel and thiotepa supported by autologous HSCT in postoperative breast cancer patients with high risk of recurrence has a good safety profile and can obtain a better benefit of DFS as compared with standard-dose chemotherapy. These results suggest that this treatment strategy deserves further exploration. Copyright © 2013 by TUMOR.

Objective To study the effects of extracorporeal shock wave therapy (ESWT) on avascular nec-rosis of the femoral head. Methods Thirty-two rabbits were used to make the avascular necrosis of the femoral headmodel by use of freezing method. Two rabbits were chosen to check the result of the model. Thirty rabbits were ran-domly divided into 2 groups : a treatment group and a control group. Each group was observed 2, 4 and 8 weeks aftertreatment. Morphological and pathological changes of the femoral head were observed. An immunohistochemicalmethod was used to examine the distribution of vessel endothelium growth factor (VEGF) and fibroblast growth factor(bFGF) immunoreactive-positive cells in the bone tissues. Results Morphologically, the femoral heads of treat-ment group were smoother and glossier than those of the control group. The empty lacunae ratio, the number of theosteoblast was significantly different between the treatment and the control group. The expression of VEGF and hFGFin the bone tissues of treatment group increased significantly when compared with control group. Conclusion ES-WT can promote healing of avascular necrosis of femoral head.

0.1), the results suggested that the stiffness of resistant torque of ITBW was similar to that of CW. In the bending test, in order to give rise to the fragmental displacement of 2.30? induced by bending load, the bending force of 3.3Nm was needed in ITBW fixation, and was 1.9 Nm greater than CW fixation, so stiffness resistant to bending of ITBW was 2.3 times of that of CW. The patients were followed up from 6 to 78 months, with an average of 38 months. There were no complications of nerve and vessels injury, infection and wire or nails loosening. Varus elbow happened in 2 cases, the mean varus angel was less than 5?. 2 cases and All the cases treated with ITBW healed uneventfully with good functions, there were excellent 32 cases and good 12 cases according to the Flynn evaluation system. Conclusion The fixation effect of ITBW is much better than that of CW. The stability provided by ITBW makes external fixation unnecessary and allows for early mobilization of the elbow. The ITBW technique is in satisfactory agreement with biomechanical principle. It is valuable for widely clinical application.

Objective To study the surgical techniques and effects of laparoscopy-assisted sigmoid colon vaginoplasty.MethodsClinical data of 27 patients,who underwent laparoscopy-assisted sigmoid colon vaginoplasty at Beijing Anzhen Hospital between June 2006 and June 2007,were retrospectively analyzed.A 15-cm segment of pedicled sigmoid colon was isolated using an ultrasound knife.The distal end of the segment was pulled into the vaginal space in the cul-de-sac of Douglas under a laparoscopic vision as the neovagina.The continuity of the intestinal tract(end-to-end bowel anastomosis) was restored using a circular mechanical suture through the rectum.ResultsThe surgery was successfully completed in all the cases,no intra-operative complication occurred.The mean blood loss and operation time was 82 ml(50-180 ml) and 168 min(120-246 ml) respectively.One patient developed incomplete intestinal obstruction 16 days after the operation,and was cured by conservative treatment.Follow-up was available in 21 patients for 14-20 months.Five patients had no sexual partner during the follow-up,while the other 16 patients were satisfied with their sexual lives after the surgeries.ConclusionLaparoscopic vaginal reconstruction using a sigmoid colon segment is satisfying for cosmetic,functional,and anatomic results.

This paper introduces the ideas and methods concerning the design of network-based curriculm of hepatobiliary surgery. Design of network-based curriculm should highlight independence of online learning,emphasize network-based resources to support learning.Net-work-based curriculm should emphasize the evaluation of learning effect.

Myopia is not only a global public health problem, but also a significant socio-economic problem. There are various hypotheses about the pathogenesis of myopia, which is basically the result of the combination of environmental and genetic factors. Although a large number of epidemiological studies have been carried out on the influencing factors of myopia, most of them are cross-sectional studies, longitudinal cohort studies are relatively few. This paper will summarize the influencing factors of myopia at homeland and abroad in recent years.

Objective To analysis the progress in prevention and control of iodine deficiency disorders (IDD) in Dalian and to provide a scientific basis for further prevention and control of the disease.Methods From 2006 to 2010,5 or 9 townships were randomly sampled from each county in Dalian,4 villages were sampled from each selected townships and 15 or 8 households were sampled from each selected villages for collecting salt samples and salt iodine level was determined by direct titration method.Sixty daytime urine samples from pregnant women,breast feeding women,infants and young children were collected,respectively,every year to detect urinary iodine level.From 2007 to 2009,2 to 11 counties were sampled and from each selected county one school was sampled to collect 100 daytime urine samples of children aged 8-10 and iodine content was determined.From 2006 to 2009,2 to 5 counties were sampled,from each selected county 2 to 5 schools were sampled and 100 children aged 8 to 10 in each selected school were sampled to detect intelligence quotient level and the thyroid volume.Results From 2006 to 2010,16 012 copies of households' edible salt samples were monitored; the average iodine content was ranged 29.68-31.51 mg/kg,the rate of qualified iodized salt in household ranged from 97.24％ to 98.42％.A total of 1398 copies of urine samples of pregnant women,486 breast feeding women,473 infants and 502 young children were monitored,and the median value of urinary iodine was 129.3-189.6,114.6-190.6,148.5-298.5 and 144.4-187.3 μg/L,respectively.A total of 1657 urine samples were monitored,1264 intelligence quotient level and 1197 thyroid volume of school-age children were determined,the median urinary iodine,thyroid goiter rate and intelligence quotient level was 217.9-266.7 μg/L,0-3.29％ and 110.4-117.2 μg/L,respectively.Conclusions From 2006 to 2010,the city's households qualified iodized salt coverage rate has reached the national standard for elimination of iodine deficiency disorders.The iodine nutrition of key population and school-age children has reached adequate level,the thyroid goiter rate is less than 5％,and the level of intelligence quotient has increased every year.But the iodine nutrition of breast feeding women in 2009 and 2010,pregnant women in 2010 is inadequate,so iodine nutrition surveillance and health education in pregnant and breast feeding women need to be strengthened in the future.
