Objective To study the expression of HOXA10 gene in the endometrium of normal fertile women and patients with unexplained infertility during different phases of menstrual cycle. Methods Endometrium samples were obtained by curettage in 52 normal fertile women and 38 patients with unexplained infertility during different phases of menstrual cycle, HOXA10 mRNA expression were detected by in situ hybridization and reverse polymerase chain reaction (RT-PCR). Results (1) HOXA10 mRNA were detected in the glandular and stromal cells of endometrium of fertile women during the menstrual cycle. By in situ hybridization (positive unite, PU), HOXA10 mRNA levels were significantly higher in the mid-secretory phase [glandular cells (G) 5.69?0.57,stromal cells (S) 7.48?0.67] and late-secretory phase(G 5.99?0.40,S 7.98?1.08) than those in late proliferative phase (G 3.35?0.20,S 3.20?0.37) and early secretory phase (G 3.07?0.26,S 3.18?0.27)(P

Hoxa gene plays an essential role in the generation and development of the human female reproductive system. This gene is expressed in the Mullerian duct and the adult female reproductive system. Expression of Hoxa10 dramatically increased during the midsecretory phase of the menstrual cycle, corresponding to the time of implantation. Female mice lacking Hoxa10 have a uterine factor defect that results in death of the preimplantation embryo and failure of implantation. These results suggest Hoxa10 may have an important function in implantation. Hoxa10 - deficient males exhibit cryptorchidism that lead to male infertility.

ObjectiveTo assess right ventricular diastolic function in patients with essential hypertension using tricuspid valve flow spectrum and tricuspid annulars motion dectected by echocardiography. MethodsAccording to Ganau′s categories, 124 patients with essential hypertension were enrolled,which were divided into four groups:normal left ventricular configurational group (group Ⅰ, n =32 ), centripetal reconstruction group (group Ⅱ, n =30), centripetal hypertrophy group ( group Ⅲ, n =32), eccentric hypertrophy group ( group Ⅳ, n =30 ). Control group consisted of 35 normal subjects pulsed wave Doppler(PW) data and tissue Doppler imaging(TDI) data were acquired from tricuspid and its' annulus respectively on apical four chamber view. ResultsEPA ＞ 1 was observed in control group as well as group Ⅰ and Ⅱ ,while E/A ＜ 1 in group Ⅲ and group Ⅳ ,there were significant differences between them. Em/Am ＜ 1 was observed in all of patients with hypertension,there were significant differences among them( P ＜ 0.05 ) .ConclusionTissue Doppler imaging was more sensitive than pulse Doppler in evaluating decreased right ventricular diastolic function in patients with essential hypertension, and the decrement of the function was different in degree based on variant left ventricular configurations.

Its urea nitrogen (BUN), reatinine (Crea), Cholesterin (CH), total protein (TP), and albumin (ALP) in blood were determined. The pathologic changes were also observed. Results: Ginkgolide has effects on renal failure caused by adenine. Low and high dose groups decrease BUN. Crea, low dose group decrese CH, high dose group increase numbers of kindney glomerulus.Conclusion: Ginkgolide has protective effect on rat's renal failure induced by adenine.

ObjectiveTo observe effects of combination of wax therapy and occupational therapy on spastic cerebral palsy with thumb adduction.Methods100 cases of children with spastic cerebral palsy were randomly divided into observation group(n=50) and control group(n=50). The observation group received occupational therapy and wax therapy, while the control group received only occupational therapy. The effect was compared between the two groups 3 months after treatment.ResultsThe two groups improved significantly 3 months after treatment, while the observation group was better than the control group(P＜0.001).ConclusionWax therapy combined with occupational therapy have better effects on thumb adduction in spastic cerebral palsy than simple occupational therapy.

Objective To investigate the imaging features of dysplasia epiphysealis hemimelica (DEH).Methods Thirteen cases of DEH confirmed by pathology (between 1.5 to 19.0 years old)underwent X-ray scan.Additionally,CT scan was performed in one patient,MR scan was performed in one,and CT and MR scan were both performed in one.Results The lesions all occurred in lower limb.There were 32 lesions,and multiple lesions were detected in 8 cases.Lesions involved holo-epiphyses in 6 cases,Twenty-three lesions were in the medial limbs,3 were in the lateral limb.With Azouz classification,the limited form was identified in 5 cases,while the classic form was identified in 8 cases.Among 13 cases,there were 4 cases with ankle eversion,3 cases with the knock knee,2 cases with the ankle inversion,and 2 cases with the strephexopodia.The metaphysis of 8 cases were widened and deformed,and the provisional zone of calcification of 1case disappeared partly and the epiphysis closed prematurely.Conclusions One or multiple eccentric enlarged ossification center of unilateral or bilateral limb is the imaging feature of DEH.There is sporadic calcification or ossification on the prophase.The calcification or ossification can fuse each other to form agglomerate at the advanced stage.The bone can deform and shift when compressed by the mass,and bone defect can even occur.

Objective To explore the role of apparent diffusion coefficient (ADC) value of diffusion-weighted imaging (DWI) in the differentiation between benign and malignant bone tumors. Methods Echo planar imaging DWI was performed in 18 patients with benign tumor or tumorous lesion and 26 patients with malignant tumor of bone. Three b-values (0, 500 and 1000 s/mm2) were applied. The lowest, highest, and whole ADC values were measured for each lesion, respectively. Results The lowest ADC values of benign bone tumor[ mean( 1.28±0. 49) ×10-3mm2/s ] were significantly higher than that of malignant tumor [ mean ( 0. 92±0. 35 )×10-3mm2/s, t = 2. 839, P < 0. 01 ]. The whole ADC values of benign bone tumor [ mean (1.62±0. 51 ) ×10-3mm2/s] were significantly higher than that of malignant tumor [ mean ( 1.21±0. 36) ×10-3mm2/s, t = 3. 092, P < 0. 01 ]. However, there were much overlapping between benign and malignant bone tumor in the lowest and whole ADC values. There was no significant difference for the highest ADC values between benign [. Mean ( 2. 02±0. 55 )×10-3mm2/s] and malignant bone tumor[ mean( 1.71±0. 65 ) ×10-3mm2/s, t = 1. 669, P > 0. 05 ]. Excluding cases of bone cyst and aneurismal bone cyst, the lowest, highest, and whole ADC values of benign bone tumor was (1.11± 0. 31 )×10-3mm2/s, ( 1.88±0. 49)×10-3mm2/s, and( 1.45±0. 35 )×10-3mm2/s, respectively. There was no significant difference for the lowest, highest, or whole ADC values between benign and malignant bone tumor (t = 1. 728, 0. 964, and 2. 012, respectively, P > 0. 05). Conclusion ADC value is useless for the differentiation between benign and malignant bone tumors.
