Conclusion There are characteristic T cells cloning proliferation and selected usage of TCR Vβ subfamily T cells could be found in metastatic lymph node.The sequences of CDR3 in different TCR clone proliferation are mostly different.

Objective:To investigate the effect of a low calcium diet on the distal and proximal tibial metaphysis in male rats using bone histomorphometrical techniques. Methods:Forty 3-month-old male Sprague-Dawley(SD) rats, with a mean weight of 280?22g, were randomized into five groups. Group one and group two were fed a normal diet (Ca 1.0%) and a very low calcium diet (VLCD ,Ca 0.1%) respectively for one month,and the rest three groups were fed a normal diet (Ca 1.0%), a very low calcium diet (VLCD, Ca 0.1%) and a low calcium diet (LCD , Ca 0.3%) respectively for three months. All animals received double bone fluorochrome labeling prior to sacrifice. At the end of experiment, the left tibiae were harvested for bone histomorphometrical evaluations. Results:After one month, compared to control group, distal tibial metaphysis(DTM) of VLCD did not change significantly but proximal tibial metaphysis(PTM) was decreased significantly whose percent trabecular area (%Tb.Ar) was decreased to 38% (P

Objective To investigate the clinical effect of ropivacaine hydrochloride at 0.25%, 0.375% and 0.5% concentration for lower limb nerve block anesthesia.Methods75 cases of lower extremity nerve block anesthesia from Ningbo Zhenhai District Hospital of traditional Chinese Medicine from September 2014 to February 2015 were enrolled in the course of the study, they were divided into three groups: group 0.25%, the equivalent number of 0.375% and 0.5% groups, and three groups of patients were made with a concentration of 0.25%, 0.375%, 0.5% ropivacaine hydrochloride for lower extremity nerve block anesthesia;the clinical data of three groups were analyzed retrospectively, observation of three groups of patients with lower limb nerve block effect.ResultsThe results showed that 0.25% groups of patients in the motor block time was (36.8±5.9) minutes, motor block in patients with a total of 7 cases, with nerve block in patients with a total of 11 cases.0.375% groups of patients in the motor block time was (23.1±4.3) minutes, motor block in patients with a total of 14 cases, with nerve block in patients with a total of 18 cases.0.5% groups of patients in the motor block time was (20.6±5.7) minutes, motor block in patients with a total of 16 cases, with nerve block in patients with a total of 18 cases.Available block time of 0.375% groups of more than 0.5% groups, less than 0.25% groups;0.375% motor block group was 56.0%, higher than the 0.25% group, lower than the 0.5% group;the 0.375% group and 0.5% group of nerve block ratio is same, higher than the 0.25% group, the difference was statistically significant (P<0.05).ConclusionThe effect of anesthesia using concentration of 0.375% ropivacaine hydrochloride is relatively good, can reduce the dosage of anesthetic drugs, but also ensure the anesthetic effect, meet the clinical requirement, this method will be applied to.

Purpose Liver fibrosis is the common pathological process of cirrhosis developed by chronic liver disease.This study aims to explore the application of microvascular change in assessing the liver fibrosis induced by bile duct ligation based on X-ray phasecontrast computed tomography (PCCT).Materials and Methods Ten rats were equally divided into the group of bile duct ligation-induced liver fibrosis and the control group at random.Then ten excised liver tissues were imaged at beamline BL13W1 of Shanghai Synchrotron Radiation Facility in China.After the imaging studies,the liver samples were stained with Sirius red and immunostained with antibodies against cytokeratin 19 (CK19).The microvasculature in livers was reconstructed via PCCT,and the correlation analysis on microvascular density and the proportion of fibrosis area was performed.Results The microvasculature including blood vessels,dilated bile ducts and ductular proliferation were clearly revealed by PCCT technology.Moreover,the 3D microvascular density and proportion of fibrosis area in the liver fibrosis group increased significantly compared with those in the control group (P＜0.01),and the correlation between them was obvious (r=0.812,P＜0.01).Conclusion Microvascular 3D characteristics of liver fibrosis are well demonstrated by PCCT,and 3D microvascular density is significantly correlated with the proportion of fibrosis area.Those findings indicate that microvascular change is closely related to the degree of liver fibrosis induced by bile duct ligation,and thus it provides a novel means to assess the severity of liver fibrosis through microvascular change.

AIM To evaluate whether l glutamine monofluorophosphate(MFP) together with Alendronate sodium may further increase bone mass in ovariectomized rats. METHODS Forty two 3 month old Sprague Dawley female rats were randomized into six groups:group 1 rats were sham operated(Sham),group 2 rats were ovariectomized controls(Ovx),and groups 3～6 were ovariectomized and received either 1 mg?kg -1 ?d -1 of alendronate sodium ,270 mg?kg -1 ?d -1 of calcium gluconate,5 6 mg?kg -1 ?d -1 of MFP or combination of 5 6 mg?kg -1 ?d -1 of MFP and 1 mg?kg -1 ?d -1 of alendronate sodium for 3 months. All animals received double bone fluorochrome labeling prior to sacrifice. At the end of experiment,the left tibiae were havested for histomorphometrical evaluations. RESULTS Alendronate sodium increased trabecular bone volume significantly with suppressed bone resorption and bone formation. Administrated calcium gluconate had no influence on the bone mass. MFP also could not restore cancellous bone of ovariectomized rats. Administration of both MFP and alendronate sodium increased bone mass significantly but did not increase bone mass compared with alendronate sodium. CONCLUSIONS The results indicated administration of both alendronate sodium and MFP could not further increase bone mass of ovariectomized rats.
