Characteristics of functional movement screening in junior middle school students / 中国学校卫生

Objective@#The influence of BMI and gender on Function Movement Screens (FMS) was analyzed to provide objective basis for improving physical quality and prevention of sports injuries among adolescents.@*Methods@#A total of 676 junior middle school students aged between 11 and 14 in grade 2 selected from a middle school in Beijing, were grouped by sex for FMS total score comparison. FMS scores of male and female students were compared according to body mass index (BMI). The 7 movements of FMS were compared and analyzed by male and female groups respectively. The influence of gender on FMS and the relationship between BMI and FMS were explored to seek the features of FMS in Chinese adolescents.@*Results@#FMS scores of male and female students in the BMI standard group were significantly higher than those of the super-recombination group(P<0.01); there was no significant difference in FMS scores between the standard group and the low weight group. BMI score was negatively correlated with FMS score, and the r value of boys was -0.27; for girls, the r value was -0.18(P<0.05). The total FMS score of male group was significantly lower than that of female group, which was (13.09±2.17) for male group and (13.91±1.79) for female group(t=-5.31, P<0.01). In comparison between men and women on each FMS test, there were significant differences in all categories except for the stability of trunk rotation (P<0.05).@*Conclusion@#Combined with BMI, FMS score can objectively reflect the overall athletic ability of adolescents. There were gender differences in FMS total score and individual score. FMS score can be used as a supplementary reference for physical fitness test of middle school students.

Stenting of iliac vein obstruction following catheter-directed thrombolysis in lower extremity deep vein thrombosis / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Catheter-directed thrombolysis (CDT) for deep venous thrombosis (DVT) of the lower extremity has good effect, but whether iliac vein stent placement after thrombolytic therapy is still controversial. The goal of this study was to evaluate the efficacy of stent placement in the iliac vein following CDT in lower extremity DVT.</p><p><b>METHODS</b>This was a single-center, prospective, randomized controlled clinical trial. After receiving CDT, the major branch of the distal iliac vein was completely patent in 155 patients with lower extremity DVT, and 74 of these patients with iliac vein residual stenosis of >50% were randomly divided into a control group (n = 29) and a test group (n = 45). In the test group, stents were implanted in the iliac vein, whereas no stents were implanted in the control group. We evaluated the clinical indicators, including patency of the deep vein, C in CEAP classification, Venous Clinical Severity Score (VCSS), and Chronic Venous Insufficiency Questionnaire (CIVIQ) Score.</p><p><b>RESULTS</b>All patients had postoperative follow-up visits for a period of 6-24 months. Venography or color ultrasound was conducted in subjects. There was a significant difference between the patency rate at the last follow-up visit (87.5% vs. 29.6%) and the 1-year patency rate (86.0% vs. 54.8%) between the test and control groups. The change in the C in CEAP classification pre- and post-procedure was significantly different between the test and control groups (1.61 ± 0.21 vs. 0.69 ± 0.23). In addition, at the last follow-up visit, VCSS and CIVIQ Score were both significantly different between the test and control groups (7.57 ± 0.27 vs. 0.69 ± 0.23; 22.67 ± 3.01 vs. 39.34 ± 6.66, respectively).</p><p><b>CONCLUSION</b>The stenting of iliac vein obstruction following CDT in lower extremity DVT may increase the patency of the deep vein, and thus provides better efficacy and quality of life.</p>

Analysis of false-positive reaction for bacterial detection of blood samples with the automated microbial detection system BacT/ALERT 3D / 中国实验血液学杂志

This study was aimed to analyze the results of false positive reaction in bacterial detection of blood samples with BacT/ALERT 3D system, to evaluate the specificity of this system, and to decrease the false positive reaction. Each reaction flasks in past five years were processed for bacteria isolation and identification. When the initial cultures were positive, the remaining samples and the corresponding units were recultured if still available. 11395 blood samples were detected. It is worthy of note that the incubator temperature should be stabilized, avoiding fluctuation; when the cultures were alarmed, the reaction flasks showed be kept some hours for further incubation so as to trace a sharply increasing signal to support the judgement of true bacterial growth. The results indicated that 122 samples (1.07%) wee positive at initial culture, out of them 107 samples (88.7%) were found bacterial, and 15 samples (12.3%) were found nothing. The detection curves of positive samples resulted from bacterial growth showed ascent. In conclusion, maintenance of temperature stability and avoidance of temperature fluctuation in incubator could decrease the occurrence of false-positive reaction in detection process. The reaction flasks with positive results at initial culture should be recultured, and whether existence of a sharply ascending logarilhimic growth phase in bacterial growth curve should be further detected, which are helpful to distinguish false-positive reactions from true positive, and thus increase the specificity of the BacT/ALERT system.

Diagnosis and surgical treatment of 48 cases of parathyroid adenoma and parathyroid carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To summarize the experience in diagnosis and surgical treatment of parathyroid adenoma and carcinoma (PTA and PTC) in our department.</p><p><b>METHODS</b>The clinical and pathological data of 48 cases admitted in our department from Jan 1995 to Dec 2005 were reviewed. Among the 48 cases, 46 cases were of parathyroid adenoma and 2 cases of parathyroid carcinoma. The average clinical history of the 48 cases was 3.65 +/- 2.83 years. The serum calcium and PTH levels were elevated in all the 48 cases. In 31 cases ultrasonographic results were consisted with that of 99mTc-MIBI scintigraphy. Unilateral neck exploration was performed in 18 cases and no case with post-operative tumor remnants was found. In other 13 cases bilateral exploration was performed but no one case was found to be tumor positive in the opposite side of the glands. Tumors resection was performed in all the 48 cases, among which in the 2 cases with PTC, ipsilateral thyroid lobe excision and modified neck dissection were also performed.</p><p><b>RESULTS</b>Clinical symptoms of all the patients were relieved after operation. No recurrent case was found during the follow-up periods (from 1 month to 10 years). The average level of serum calcium and PTH declined significantly after operation. The post-operational serum calcium and PTH levels at 3 days after operation were even lower than normal. Transient post-operational hypocalcemia was found in almost all the patients. The serum calcium and PTH levels in all patients recovered to normal level within a periods from 1 week to 3 months after operation. The sensitivity and positive prediction value of localization methods were 97.0% and 94.1% of ultrasonography, respectively, and 100% and 97.3% of 99mTc-MIBI scintigraphy, respectively.</p><p><b>CONCLUSION</b>Patients with chronic bone diseases, repeatedly recurrent nephrolithiasis, peptic ulcer disease or pancreatitis should be regarded as suspicious cases of PTA and PTC, and serum calcium assay should be performed as a routine screening procedure. Serum calcium and PTH assays are both reliable methods for the diagnosis of PTA and PTC. A combination of ultrasonography and 99mTc-MIBI scintigraphy is sufficient for locating adenomas. Accompanied by intraoperative pathological examination, unilateral neck exploration is an acceptable approach for patients with definitely preoperative confirmed adenoma localization.</p>

The anti-rejection effect of blocking BT/CD28 co-stimulatory pathway by RNA interference in mice heart transplantation / 中华器官移植杂志

Objective To explore the influence of blocking B7/CD28 co-stimulatory pathway by RNA interference on the rejection response in mice heterogeneous heart transplantation and its mecha- nism.Methods siRNA of which sequence specified to CD80 and CD86mRNA was synthesized in vitro respectively and transfected into donor derived myeloid dendritic cells (DCs).The expression levels of CD80 and CD86 mRNA and surface antigen CD80,CD86 were assayed by semi-quantitative reverse transcription polymerase chain reaction and flow cytometry before and after CD80siRNA and CD86siRNA transfection.Seven days prior to heterogeneous heart transplantation in mice,DCs modi- fied by siRNA were transfused into recipients intraveneously (DC interference group).At the same time,group of allograft transplantation,cyclosporine A (CsA)-treated (CsA injected subcutaneously postoperatively,5 mg.kg~(-1)?d~(-1)) group,group of isograft transplantation,and non-interference DC group (transfusion of non-interfered DCs pre-transplanting) were assigned.The graft survivals were individually recorded and the graft rejection grading was pathologically evaluated.Interleukin 2 (IL- 2),interferon?(IFN-?),and IL-10 mRNA expression levels in grafts tissue were determined.Results After siRNA transfected into DC,the expression levels of CD80 and CD86 mRNA were down- regulated significantly and the the antigen CD80~+ and CD86~+ reduced from 84%,67% to 35% and 30% respectively.As compared with groups of allograft and non-interference DC,survival of the grafts was significantly longer in DC interference group (P＜0.01),pathological grade of rejection significantly lower (P＜0.01),IL-2 and IFN-?mRNA expression levels lower,and IL-10 mRNA ex- pression levels higher in grafts tissue (P＜0.01).Conclusion Knocking down the molecule B7 expres- sion level in donor-derived myeloid DCs through RNAi,which could block B7/CD28 co-stimulatory pathway,could exhibit inhibitive effect on rejection response in mice heart transplantation.The mechanism might be due to induction of T lymphocyte anergy and Th cell differentiation deviating to T_H2.

The mRNA expression level of vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9) were measured by quantitive reverse transcription polymerase chain reaction (Q- RT-PCR).</p><p><b>RESULTS</b>The AP-1 DNA binding activity in T was significantly higher than those in P(2), P(5) and N (P< 0.05) tissues. There were significantly positive correlations between AP-1 DNA binding activity in tumor and invasive degree, lymphatic metastasis respectively (P< 0.01), but no correlation with histological classification and differentiation (P> 0.05). The transcription levels of VEGF and MMP-9 in CRC were significantly higher than those in P(5) and N (P< 0.01, P< 0.05) tissues. The transcription levels of VEGF and MMP-9 were significantly correlated with increasing AP-1 DNA binding activity (P< 0.01).</p><p><b>CONCLUSIONS</b>AP-1 is significantly correlated to the invasion and metastasis in CRC. The activation of AP-1 signal transduction pathway might be involved in the angiogenesis and of degradation extracellular matrix during tumor metastasis.</p>

A study on correlation of hepatic metastasis of colorectal cancer to vascular endothelial growth factor, angiopoietin-2, and fibronectin / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To study the correlation of hepatic metastasis of colorectal cancer to vascular endothelial growth factor (VEGF), angiopoietin- 2 and fibronectin (FN).</p><p><b>METHODS</b>The transcription and expression of VEGF, angiopoietin- 2 and FN were detected by semiquantitative reverse transcription- polymerase chain reaction (SQRT- PCR) and immunohistochemical staining in the specimens from sixty patients with colorectal cancer.</p><p><b>RESULTS</b>The mRNA transcription and expression levels of VEGF, angiopoietin- 2 and FN in colorectal cancer tissues were obviously higher than those in paratumor normal tissues P< 0.05. The transcription and expression levels of VEGF were correlated with tumor invasion P< 0.05,Dukes' stage P< 0.05,and lymph node and/or hepatic metastasis P< 0.05. Angiopoietin expression and transcription levels were correlated with tumor differentiation. The expression of FN in extra cellular matrix (ECM) was significantly higher (P< 0.05),whereas ECM in basement membrane was significantly lower in cancer tissues than that in paratumor normal tissues (P< 0.05),which both were correlated with tumor invasion P< 0.05,Dukes' stage P< 0.05,and lymph node metastasis P< 0.05. Absence of FN protein in basement membrane was also correlated with hepatic metastasis.</p><p><b>CONCLUSION</b>Colorectal cancer cells can secrete VEGF and contribute to metastasis and proliferation of tumor by stimulating the growth of tumor vessel. Both of VEGF and angiopoietin- 2 contribute to angiogenesis and the decrease of FN in basement membrane of cancer tissue is an important primary factor of hepatic metastasis.</p>
