Results: The Granules significantly increased the contractile amplitude, frequency and vitality of both rat uterine smooth muscless in vivo and human uterine strips isolated.Conclusion: The Granules can be used in the treatment of the postpartum hemorrhage and the poor uterine involution caused mainly by lacking in the strength of uterine contraction.

Objective To observe the safety of telbivudine (LdT) application throughout pregnancy in women with chronic hepatitis B (CHB),and to provide evidence-based treatment recommendations for women of childbearing age with chronic hepatitis B.Methods Women with hepatitis B virus (HBV) infection who took LdT before pregnancy and in early pregnancy were followed up prospectively for evaluating maternal and newborn adverse events.All newborns received block of HBV mother-to-child transmission (MTCT) after birth and were followed up for neonatal disorders and effects of maternal and child block.Results Among the 145 cases of pregnant women,143 were diagnosed as CHB and 2 decompensated cirrhosis.One hundred and five (72.4％) patients had HBV DNA＜500 copy/mL and 125 (86.0％) had positive hepatitis B e antigen.There were total 154 times pregnancies including 17 spontaneous abortions,4 ectopic gestation and 9 pregnancies after abortion.One hundred and one cases finished pregnancy,with 100 full term deliveries,1 preterm delivery and 2 twin pregnancies.One fetal with cleft lip and palate was aborted by induced labor in 24 weeks gestation.One baby was born with right double ears; one had benign lymph node under the left ear; and another one was diagnosed with congenital heart disease.Seven of the pregnant women had creatine kinase increased.Eight developed drug resistance.However,none had disease progression during pregnancy.None of the 63 infants was hepatitis B surface antigen positive over the 6 months of follow-up.The prevention of HBV MTCT was 100％ successful.Conclusion It is safe and effective for women with chronic HBV infection to receive LdT treatment throughout pregnancy.

ObjectiveTo analyze the MR imaging features of epileptogenic focal cortical dysplasia (FCD)and to optimize the scanning protocols by correlating MRI appearance with pathological findings.MethodsMRI findings and the relative scanning protocols in 36 patients with surgically and pathologically proved 40 lesions of FCD were retrospectively analyzed. According to Palmini classification system,all 40 lesions were pathologically categorized as FCD type Ⅰ (including FCD Ⅰ A and FCD Ⅰ B) and FCD type Ⅱ (including FCD Ⅱ A and FCD ⅡB ). The distribution of cerebral or dual lesions accompanied hippocampal sclerosis were observed.Differences of the distribution of cerebral in FCD type Ⅰ and FCD type Ⅱ were compared by using Fisher exact probabilities. MR scans in all patients consisted of routine and optimized protocols.Axial FSE T2WI,axial SET1WI and axial FLAIR were recognized as routine scanning protocols,while adding oblique coronal FSE T2WI and FLAIR were recognized as optimization scanning protocols.Both routine and optimization scanning protocols were performed in all patients.The conspicuity of main findings of FCD on different imaging plane and sequences of each protocol were assessed.The detection of cerebral or dual lesion and the accompanied hippocampal sclerosis were compared between the routine protocol and the optimized protocol by using McNemar test.ResultsForty lesions were found in 36 cases with FCD,29 had temporal lobe lesion (72.5％ ),9 had frontal lobe lesion(22.5％ ) and 2 had parietal lobe lesion (5.0％).According to Palmini classification system,29 lesions in 27 patients (72.5％ ) were FCD type Ⅰ,11 lesions in 10 patients (27.5％) were FCD type Ⅱ lesions.There were 25 temporal lobe lesions in FCD type Ⅰ,while 4 in FCD type Ⅱ.There were statistically significant differences between FCD type Ⅰ group and FCD type Ⅱ group in the distribution of cerebral (P =0.002 ).Fourteen cases were found to have hippocampal sclerosis simultaneously,with 13 cases found in FCD type Ⅰ patients and 1 case in type Ⅱ patients.The detection rate of temporal lobe lesion was 65.5 ％ (19/29) and 44.8 ％ ( 13/29 ) respectively on optimized protocol and routine protocol.There was statistically significant difference ( x2 =4.167,P =0.031 ).The detection rate of hippocampal sclerosis was 85.7％ (12/14) and 42.9％ (6/14) respectively on optimized protocol and routine protocol respectively.There was statistically significant difference ( x2 =4.167,P =0.031 ).The detection rate of frontal lobe lesion showed no statistically significant difference between optimized protocols and routine protocols (x2 =0.304,P =1.000 ).Conclusions FCD was frequently involved the temporal lobe,followed by the frontal lobe.FCD type Ⅰ lesion was frequently found in the temporal lobe,with a higher incidence of concomitant hippocampal sclerosis. The optimized whole temporal lobe scanning with imaging plane perpendicular to the hippocampus long axis was a highly desired scanning protocol specifically for FCD,which is helpful for the detection of the FCD lesions.

Objective To establish a new processing method for gait data on Matlab to evaluate the hindlimbs behavior of non-human primates. Methods Gait analysis was tested on three rhesus monkeys 6 weeks after spinal cord injury, and kinematics data of hindlimbs were obtained using the VICON system. The raw data of kinematics were filtered and extracted, which were achieved through VICON 3D motion capture system with the Excel link combining Matlab with Microsoft Excel, and calculated in the Matlab environment. Results The kinematic parameters such as step length, step height, knee joint angle, and malleolus joint angle were gained by calculating. The mean values of step length (F=2.869, P=0.088) and step height (F=1.148, P=0.344) showed no significant difference at three speeds, which implied a higher repeatability of the data model. Angle-time curve reflected the joint function and movement. This system initially described the foot gait trajectory which could be used in gait repetitive analysis, and also generated the gait 2D/3D trajectories of hindlimbs. Conclusion The implement of these functions makes the post-processing of data more flexible and open whitout VICON system, and the calculated parameters and space tracing of gait trajectory basically meet the need of hindlimb behavior evaluation for nonhuman primate.

Objective To evaluate the CT findings and classification of the Le Fort fracture. Methods Sixty-two cases with Le Fort fractures were studied with thin-slice high-resolution CT scanning and analyzed with three-dimensional(3D)imaging reconstruction.Results Of the 62 patients,10 had Le Fort type Ⅰ fracture,9 had Le Fort type Ⅱ fracture,8 had Le Fort type Ⅲ fracture,and 35 had various combinations of the three types of Le Fort fractures,including 18 Le Fort Ⅰ+Ⅱ fracture,7 Le Fort Ⅰ+ Ⅱ+Ⅲ fracture and 10 Le Fort Ⅱ+Ⅲ fracture.Fifty-five cases had associated multiple fractures in the maxillofacial region.On 2D CT images,Le Fort fracture manifested as multiple and complex fractures. Though 2D image was better than 3D image in accurately defining tiny fractures and fractures of deep structures,the diagnosis of Le Fort fracture could not be correctly made solely on 2D image.3D CT clearly and stereoscopically demonstrated the entire shape and orientation of Le Fort fracture,thus facilitating the correct classification of Le Fort fracture.Conclusion 3D CT image is important in providing information about the space relationship of Le Fort fracture,thus very valuable for the preoperative planning.

objective To identify the three strains of pink-pigmented bacteria isolated from ticks.Methads 16S rDNA sequence analysis,16S rDNA similarity searching,bacterial morphological,physiological and biochemical tests and fatty acids analysis were used.Results The bacterial strains were pinkpigment,gram negative,strictly aerobic coccobacillus.They grow optimally at 37℃,while not in the presence of≥5% NaCl.The tests showed positive result for urease,D-glucose,citrate,UV absorption,and catalase.The predominant fatty acids were C16:0,C17:0,C18:1 ωgc and C19:0 cyc.Comparative 16S rDNA sequences analysis revealed that the strains were closely related to Roseomonas cervicalis and could reach up to 99.1% identity.Conclusion Based on phenotypic,biochemical and phylogenetic data,we propose these three isolates represent distinct species in genus Roseomonas,of which ticks may serve as a potential vector.

ObjectiveTo evaluate the characteristics of patients on long-term peritoneal dialysis (PD). MethodsPatients who started PD since 1994 and received PD for at least one year were included in this study. According to dialysis duration, patients were divided into two groups. Group A (long-term) was defined as patients survived on PD for more than 5 years. Group B (short-term) was defined as patients who died or switched to bemodialysis within less than 5 years. Demography, biochemical indexes, dialysis prescription and adequacy were compared between two groups. ResultsThere were 68 patients in group A and 98 patients in group B. Mean followed-up period of group A and B was (84.80±19.42) months and (27.25±12.31) months, respectively. Younger, fewer episodes of diabetic comorbidity (group A 3/68 vs group B 18/98, P ＜0.05) and coronary heart disease (group A 6/68 vs group B 22/98, P＜0.05) were found in group A. Compared to group B, the level of serum albumin at the beginning of PD was much higher in group A [(35.56±4.74) g/L vs (33.69±5.45) g/L, P＜0.01). The levels of blood sugar, TC, TG, hemoglobin, calcium, phosphate and iPTH were not significantly different between two groups. Estimated GFR, renal Kt/V and renal Ccr at the beginning of dialysis were much higher in group A, however there was no significant difference in urinary volume between two groups. Both estimated GFR and urinary volume decreased more slowly in group A compared to group B. Peritonitis mobidity was lower in group A (1/81.22 months vs 1/29.03 months, P＜0.01). Conclusions In comparison to short-term survivors, long-term PD patients are characterized by being younger, less diabetic and coronary heart disease, fewer episodes of peritonitis, higher level of serum albumin, higher estimated GFR and less loss of residual renal function.

Objective To study the clinical manifestation,diagnosis and treatment of the renal myxofibromata.Methods Combined with reviewing the relevant literature,we retrospectively analyzed the clinical data of a case of renal myxofibromata.A 47-year-old female patient was found left renal cystic lesion by ultrasound 8 months before admission.CT showed a 4 cm cystic and solid lesions in the lower pole of left kidney,which was similar to the results of ultrasound.The enhanced abdominal CT and dynamic contrast-enhanced ultrasound showed that the lesions could be enhanced slowly with uneven density.The patient underwent left kidney exploration under the general anaesthesia.During operation,a round solid mass about 5 cm in diameter can been seen in the low part of renal sinus,which was a bit hard.The mass was close with surrounding tissue.Then,the left kidney was excised.Results The surface of the mass was full and smooth with pale yellow luster.In the HE section,the tumor was composed with fibroma like cell,which demonstrated the inhomogeneous size,shape and irregular organization.The nucleus showed the spindle shape,with rare mitosis phase.Large quantity of mucus and vascular tissue could be observed in the tumor.Few fibroblast cells could also be found in the section.The pathological result was myxofibromata (immature) with malignant tendency.No special treatment was given after surgery.Recurrence was not recorded within 6 months following-up.Conclusions Commonly,the myxofibromata is a kind of benign tumor.Only a few can result in the malignant transformation and distant metastasis.Primary renal myxofibromata is extremely rare.The preoperative imagine manifestation is difficult to provide the accurate diagnosis.Pathologic result is the gold standard in diagnosing this disease.Actively surgical treatment and regular following-up after surgery should be considered.
