OBJECTIVETo investigate the mothod and therapeutic efficacy of total hip anthroplasties (THA) for osteoarthritis secondary to Crowe type IV developmental dysplasia of hip in adults.

METHODSFrom May 2006 to December 2013, THA was performed on 15 adult patients (17 hips) with Growe type IV acetabular dysplasia, including 13 females and 2 males, with a mean age of 30.9 years old (22 to 58 years old) and an average preoperative Harris score of (34.0 ± 6.5) points. Traction of the affected limb was not performed before surgery. After extensive release and lengthening of soft tissues, sub-trochanteric osteotomy of the femur was performed, hip joint center was rebuilt and the abduction function was restored.

RESULTSThe patients were followed up with a mean period of 33 months (ranged from 6 months to 5 years). The postoperative Harris score was 85.0 ± 7.3,higher than the preoperative score. The extended length of limb ranged from 1.6 to 5.4 cm, with a mean of (3.42 ± 0.65) cm. The shortening and malformation of the affected limb were corrected in the most patients,with the difference in length of the two legs less than 1.5 cm. After surgery, 1 patient experienced partial sciatic nerve injury, which was largely recovered after 3 months of conservative treatment. One patient experienced complete sciatic nerve injury, which was partially recovered after 6 months of conservative treatment; a foot-drop varus deformity was formed in the distal end of the affected limb, which was improved after tendon transposition and transplantation. Joint pain was relieved, and the joint function was restored significantly. Over the follow-up period, no severe complications such as dislocation, infection, prosthesis loosening, or subsiding occurred.

CONCLUSIONSatisfactory efficacy can be achieved for adult Growe type IV acetabular dysplasia associated with osteoarthritis by THA, with proper soft tissue release and lengthening, sub-trochanteric osteotomy of femur, joint functional restoration, appropriate choice of prosthesis, and careful protection of nerves and vessels.

Background and purpose:TrkB,a neurotrophic tyrosine kinase receptor,serves as a potent and specific suppressor of anoikis of non-malignant epithelial cells,and induces high invasion capacity in these cells.TrkB over-expression has been associated with chemotherapy resistance and poor survival in neuroblastoma and some other highly aggressive cancers.However,the relationship of the expression of TrkB to anoikis resistance in ovarian cancer cells has rarely been reported in literature.This study investigated the expression and significance of anoikis- suppressor TrkB in OVCAR-3 ovarian cancer cells.Methods:The expression of TrkB and its ligand BDNF was evaluated in OVCAR-3 ovarian cancer cells under different culture conditions by RT-PCR and Western blot.Results: TrkB mRNA was overexpressed in multicellular spheroids(cell-spheroids,anchorage-independent culture,AIC)as compared to that in OVCAR-3 cells(adhesive-cells,adhesive culture,AC),(35.3?0.7)% versus(23.5?0.5)%;but BDNF mRNA expression was the opposite to the above situation,(41.4?0.6)% versus(32.24?0.7)%(P

OBJECTIVETo observe the efficacy on primary osteoporosis treated with spreading moxibustion for warming yang and activating blood circulation so as to provide the effective clinical therapeutic methods for osteoporosis.

METHODSSixty cases of primary osteoporosis were randomized into a spreading moxibustion group (30 cases) and a calcium tablet group (30 cases). In the calcium tablet group, caltrate was prescribed for oral administration, 600 mg per day. In the spreading moxibustion group, on the basis of the treatment as the calcium tablet group, the spreading moxibustion was applied at Dazhui (GV 14) to Yaoshu (GV 2) for warming yang and activating blood circulation. The duration of treatment was 12 weeks. Visual analogue scale (VAS) score, TCM clinical symptom score and bone mineral density (BMD) were observed and compared before and after treatment in the patients between the two groups.

RESULTSVAS scores were reduced apparently after treatment in the two groups (both P < 0.01) and the results in the spreading moxibustion group were obviously superior to that in the calcium tablet group (2.36 +/- 0.43 vs 4.52 +/- 0.35, P < 0.01). BMD were all increased in the two groups (P < 0.05, P < 0.01) and the results in the spreading moxibustion group were superior to those in the calcium tablet group (both P < 0.05). The total clinical effective rate was 86.67% (26/30) in the spreading moxibustion group, apparently better than 63.33% (19/30) in the calcium tablet group (P < 0.05). TCM clinical symptom scores after treatment were all reduced apparently in the two groups (both P < 0.01), and the result in the spreading moxibustion group was obviously superior to that in the calcium tablet group (4.72 +/- 1.90 vs 6.82 +/- 2.30, P < 0.01). The total effective rate of TCM symptoms was 93.33% (28/30) in the spreading moxibustion group, apparently better than 70.00% (21/30) in the calcium tablet group (P < 0.05).

CONCLUSIONThe combined therapy of spreading moxibustion for warming yang and activating blood circulation and the oral administration of caltrate apparently relieves pain and TCM clinical symptoms, improves BMD in the patients of osteoporosis and achieves definite clinical efficacy in the patients of osteoporosis.

Objective To improve the acknowledge of diagnosis and therapy of aggressive systemic mastocytosis (ASM).Methods One ASM patient was reported and the literatures were reviewed.Results As a rare subtype of SM,ASM is characterized by multiple organs involvement,and often accompanied by bone marrow dysfunction,osteolytic lesions and palpable hepatomegaly or splenomegaly which usually indicate the high mast cell burden.Conclusion ASM meets criteria for SM and has one or more C findings.Variable factors affect the prognosis of ASM patients and the formulation of the clinical treatment strategy which leads to the highly individualized therapies.

Objective To determine the levels and significance of Krebs von den lungen-6(KL-6), pulmonary surfactant protein A (SP-A), SP-D and interleukin (IL)-6 in patients with connective tissue disease interstitial lung disease (CTD-ILD). Methods The serum KL-6, SP-A, SP-D and IL-6 in all subjects were detected and the imaging and pulmonary function were recorded t test, χ2 test, non-parametric test, ANOVA and correlation analysis were used for data analysis. Results ① The levels of serum KL-6, SP-A, SP-D, IL-6 in the CTD-ILD group [551.4 (428.2, 883.5) U/ml, 938.4(435.2, 2324.7) pg/ml, 90.7 (80.7, 100.3) ng/ml and 30.4 (22.9, 41.7) pg/ml; P all<0.05] was significantly higher than that in the CTD group [192.9 (139.2, 266.2) U/ml; 458.0 (372.6, 529.0) pg/ml; 80.0 (71.2, 98.3) ng/ml; 18.6 (4.9, 31.0) pg/ml, Z=-5.383, -3.76, -2.123,-3.903, P all <0.05]; and higher than healthy controls (n=30) [183.2(141.9, 216.6) U/ml; 229.0(162.0, 248.0) pg/ml;50.8(26.1, 96.4) ng/ml;7.1(3.7, 8.7) pg/ml, Z=-5.801,-8.13, 2.272, 3.266;P all<0.05].②The levels of KL-6 in pulmonary HRCT for active ILD group was significantly higher than the non-active ILD group [998.5 (640.3, 1293.3) U/ml vs 565.0(434.0, 799.5) U/ml, Z=2.182, P=0.023], there was no statistical difference in the levels of SP-A, SP-D, IL-6 between the 2 groups. ③ Spearman correlation analysis showed that KL-6 was negatively correlated with forced vital capacity (FVC%);SP-D, IL-6 and diffusing capacity of carbon monoxide (DLCO %). ④ Logistic multiple regression analysis showed that KL-6 [OR=1.017, P=0.002, 95%CI (1.006, 1.028)], SP-A [OR=1.023, P=0.009, 95%CI (1.006, 1.041)], SP-D [OR=1.175, P=0.009, 95%CI (1.075, 1.264)], IL-6[OR=1.213, P=0.001, 95%CI(1.088, 1.354)] were the risk factors for ILD. Conclusion Serum KL-6, SP-A, SP-D and IL-6 are significantly increased and correlate with CTD-ILD. KL-6 is related to the pulmonary inflammatory disease and vital capacity, while SP-D and IL-6 are related to diffusion function.

Objective To investigate the changes and prognostic significance of bone marrow(BM) oil drop and megakaryocyte counts after chemotherapy in acute myeloid leukemia (AML) patients (non-M3).Methods Ninty-nine adult patients with denovo AML (non-M3) were retrospectively analyzed to evaluate the change of BM oil drop and megakaryocyte counts and their influences on overall survival(OS) and disease free survival (DFS) during all stages of standardized therapy.Results The median DFS and OS were 21 (2-88);months and 70 (4-89) months,respectively; and 3-year predicted DFS and OS were 47.3 ％ and 55.8 ％,respectively.After AML patients (non-M3) achieving complete remission (CR) by induction therapy,BM oil drop tended to increase along with postremission chemotherapy cycle accumulation, while megakaryocyte counts tended to decrease.The univariate analysis indicated that megakaryocyte counts decreased after the second course of postremission therapy. BM oil drop increased after the first to the third course of postremission therapy.Grade of myelofibrosis in BM biopsy,serum lactate dehydrogenase (LDH) level at diagnosis,flow cytometric immunophenotyping, the percentage of BM blast cells at diagnosis and the percentage of residual leukemic cells (RLC) during aplasia (7-10 days after the end of induction therapy) had prognostic significance.Multivariable COX analysis indicated the percentage of BM blast cells at diagnosis and change of BM oil drop after the third postremission therapy were independent prognostic factors for DFS (P =0.010,0.018 respectively),and RLCs during aplasia and change rate of the megakaryocyte counts after the second postremission therapy were independent prognostic factors for OS (P =0.009, 0.038respectively).Conclusion After AML patients (non-M3) achieving CR by induction therapy,BM oil drop tends to increase along with postremission chemotherapy cycles accumulation,while the megakaryocyte counts tend to decrease.Dynamic observations of bone marrow oil drop and megakaryocyte counts are helpful for assessing the prognosis of acute myeloid leukemia (non-M3).

Objective To evaluate the roles of magnetic resonance imaging and proton magnetic resonance spectroscopy(1H-MRS) in the diagnosis of meningiomas. Methods 98 patients with meningiomas underwent conventional pre-contrast MR and contrast MR. Among them, 28 cases had two dimensional single voxel or multi voxel 1 H-MRS simultaneously both in the lesion's region and the contralateral side. Results On precontrast MR images of 98 cases, T1 WI showed 58.1% (61/105) isointensities, 31.4% (33/105) faintly low intensities and 10. 5% (11/105) mixed intensities; T2WI showed 40. 0% (42/105) isointensities, 41.0%(43/105) hyperintensities, 10.5% (11/105) faintly low intensities and 8.5% (9/105) mixed intensities. After administration of Gd-DTPA, the solid part of the tumors exhibited various enhancement in all the 98 cases.28 cases of MRS exhibited specific different spectral peaks, including increased of choline-containing compounds(Cho), absent or decreased of acetylaspartate(NAA), and the unchanged of creatine(Cr). The value of NAA, Cr, Cho, NAA/Cr, Cho/Cr, NAA/Cho in the tumor center of meningioma were 0. 09 ± 0.06,0.31 ± 0. 22, 0.46 ± 0. 16, 0.33 ± 0. 42, 1.50 ± 0. 68, 0. 15 ± 0.08, compared with the contralateral normal region, Cr has no significant difference (P ＞ 0. 05), NAA, Cho, NAA/Cr, Cho/Cr, NAA/Cho had significantly differences(P ＜ 0.05). Conclusion Conventional pre-contrast MR and contrast MR is the most important dignostic means for meningiomas, 1H-MRS combined with MRI can improve the diagnostic accuracy of meningiomas.

An in vitro model was built for researching the effects of strain on vascular smooth muscle cells (VSMCs). The cultured VSMCs was stretched by four-support-bending-beam system, then the project area of cells was measured by computer-image-processing, the adhesion force was measured by micropipette-aspirating system, the α-actin of VSMCs was distinguished by immunocytochemistry and the dynamic of VSMCs was determined by FCM. The results show that: (1) The adhesion force of VSMCs is positively related to time. The adhesion force of unit area is indistinct after stretched for four hour. (2) The amount of α-actin increases with stretching time. (3) The proliferation of VSMCs is a little inhibited by stretched 24 h. These results suggest that the VSMCs in vitro could adjust their behavious to adapt the tension.

Orobanche caerulescens is an important medicinal resource in Orobanchaceae. The present study aims to establish methods for determination of acteoside, crenatoside, and total phenylethanoid glycosides in O. caerulescens, and determine the content in 15 samples to evaluate the resource utilization of this medicinal plant. The content of acteoside and crenatoside were quantitatively determined by HPLC, while total phenylpropanoid glycosides was estimated by UV-VIS spectrophotometry. According to the results, the content of acteoside was the highest in O. caerulescens, followed by crenatoside. The contents of acteoside, crenatoside, and total phenylethanoid glycosides were between 1.15% - 15.60%, 0.83% - 4.47%, and 6.78% - 27.43%, respectively, which had significant differences. The acquisition time has great influence on the content of main components of O. caerulescens. The content of phenylethanoid glycosides is higher in the samples which were collected at the flowering stage. The two determination methods were proved to be simple, accurate and reliable, and can be used to evaluate the quality and resource utilization of O. caerulescens.

Objective　To evaluate the effect of Naogongfude (NGFD, a traditional Chinese medicine orally administrated) on learning and memory and the expressions of synaptophysin (SY) and Tau-protein in cerebral cortex and hippocampus in aged rats and to explore the possible mechanism. Methods　Rats were divided into normal and neural disturbance groups according to the outcomes of active avoidance reaction (AAR) test, and then each group was randomly divided into control and NGFD-treated experimental groups. Animals were orally fed with NGFD for 2 months (5 ml/d) in experimental group or routinely fed in control and taken AAR and passive avoidance reaction (PAR) tests. After the rats were sacrificed, the synaptosome count, the expression of SY and Tau-protein, and the neuron apoptosis in cerebrum were examined. Results　The rats after 2-month NGFD administration had an increased AAR acquisition, obviously delayed AAR extinction and prolonged step through latency (STL) of PAR. The number of synaptosomes was raised and the immunoreactive intensity of synaptophysin was increased remarkedly, while Tau-protein immunoreactivity and apoptotic cells were decreased in cerebrum. Conclusion　NGFD does have the effect of improving brain function and putting off the aging of rat brain according to the results of behavior study and morphological observation.
