[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.

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.

To observe the diopter after cataract surgery for vision gain in high myopia and its effect on visual outcomes.METHODS: Sixty ( 120 eyes ) high myopia combined with cataract cases received phacoemulsification and intraocular lens implantation in our hospital were retrospective studied. The patients were divided into three groups based on postoperative diopter: -1. 0 ~ -2. 0D (group A), -2. 25~-3. 0D (group B) and -3. 25 ~-4. 0D ( group C ) . The uncorrected distance visual acuity ( UCDVA) , best corrected distant visual acuity ( BCDVA) , uncorrected near visual acuity ( UCNVA ) and questionnaire of Activities of Daily Vision Scale ( ADVS ) were collected to assess the vision gain at 3mo after cataract surgery.RESULTS: At 3mo after surgery, UCDVA of group A was better than that of group B, and UCDVA of group B was better than that of group C. There were no differences in BCDVA among groups. There were significant differences between the three groups' UCNVA, it was best for the group C, followed by the group B, group A was the worst. For questionnaire, no difference was observed in patients' satisfactory for surgical results, but a significant difference was detected in postoperative glasses wearing frequency between groups.CONCLUSlON: For cataract surgery in high myopia combined cataract, postoperative diopter should be calculated based on patients' daily requirements. For patients had not used to wearing glasses and near distant working condition, it's appropriated to reserve a minor degree of myopia. Conversely, for patients require near distant working and received wearing moderate and low hyperopia mirror, higher degree of myopia can be reserved.

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 investigate the mechanism of high-glucose-induced injury to human peritoneal mesothelial cells(HPMC). Methods (1)The cultured HPMCs were exposed to culture medium containing different concentrations of glucose(1. 5% , 2. 5% , 4. 25% )for 48 hours and 4. 25% mannitol and normal culture medium were as control. Then apoptosis was observed by flow cytometry and caspase-3 activity was measured by ApoAlert?CPP33/Caspase-3 Assay kits. (2) The cultured HPMCs were exposed to 4.25% glucose culture medium containing different concentrations of caspases inhibitor, Z-VAD. fmk (25, 50, 100 ?mol/L) for 48 hours and 4. 25% glucose culture medium containing DMSO was as control. Then apoptosis was observed by flow cytometry and caspase-3 activity was measured by ApoAlert?CPP33/ Caspase-3 Assay kits as well. Results (1) Glucose increased caspase-3 activity in a concentration-dependent manner. Compared to control, caspase-3 activity was significantly higher in 4. 25% glucose group and 2. 5% glucose group, but not significantly different in 1. 5% glucose group and 4. 25% mannitol group. (2) Apoptotic rate of HPMC was significantly lower in Z-VAD. fmk group than that in control. Z-VAD. fmk decreased the number of apoptotic cells in a concentration-dependent manner. Also, caspase-3 activity of HPMC was significantly lower in Z-VAD. fmk group than that in control. Conclutions (1) High-glucose can induce apoptosis and caspase-3 activation of HPMC in a dose-dependent manner. (2) Z-VAD. fmk inhibits high glucose-induced apoptosis of HPMC in a dose-dependent manner. (3)High glucose induces apoptosis of human peritoneal mesothelial cells by caspase-3 activation.
