Chinese Journal of Tissue Engineering Research 2016;20(29):4383-4388
BACKGROUND:At present, it is a hot spot to study the relationship between digit or phalange length ratios and athletic ability. However, the results from various studies cannot be verified each other because there are controversies about the research objects and the research technique in the area. Therefore, it is necessary to point a right direction for the research in this field. OBJECTIVE:To explore the relationships of digit and phalange length ratios to athletic ability and the existing problems by literature search strategies and logic thinking methods. METHODS:A computer-based online search was conducted in Elsevier Science-direct, PubMed, EM, CNKI, and CJFD databases by using the key words of“digit length ratio, 2D:4D, phalange length ratio, athletic ability”from 1990 to 2015. The language was limited to both Chinese and English. 358 relevant articles were screened, and 42 eligible articles were included final y. RESULTS AND CONCLUSION:Currently, studies show that there are some relationships between digit phalange length ratio or phalange length ratio and athletic ability. There are controversies about the research results due to the diverse study methods and techniques. It is necessary to define the digit phalange length ratio or phalange length ratio in the human study. The most advanced techniques should be considered to reduce the measurement bias. Moreover, multi-angle, multi-level studies should be performed to reveal the relationship of digit phalange length ratio or phalange length ratio to athletic ability. Human digit phalange length ratio or phalange length ratio, particularly 2D:4D can reflect the aerobic exercise capacity of athletes.

Objective · To design an immuno-affinity chromatography device for the separation and detection of syphilis specific antibody, then verify its performance of detection and clinical application. Methods · Affinity filler packed by Treponema pallidum (TP) antigen in affinity chromatography can specifically adsorb TP specific antibody (including IgG and IgM) in samples. After balance, elution and desalination, IgG or IgM gold labeled chromatography strip detects the possibly present syphilis specific IgG or IgM antibody. Twenty cases of syphilis antibodynegative samples and 230 cases of syphilis antibody positive clinical specimens were detected by this chromatography device, and 40 cases were also detected by Western blotting.Results ·The standard operation procedure of the affinity chromatography device was optimized, which could effectively detect the specific IgG and IgM antibody of syphilis. The results of 20 syphilis antibody negative samples were all negative. In 230 syphilis antibody positive cases, the detection results were 2 cases with TP-IgG(-) and TP-IgM(-), 210 cases with TP-IgG(+) and TP-IgM(-),10 cases with TP-IgG(-) and TP-IgM(+), and 2 cases with TPIgG(+)and TP-IgM(+). The detection results of 40 cases were compared with the results detected by Western blotting, among which 2 cases detected by affinity chromatography device were TP-IgG(-) and TP-IgM(-), while the results detected by Western blotting were TP-IgG(+) and TP-IgM(-). But the results of the two methods showed no statistically significant difference (P>0.05). Conclusion · The application of the device in separation and detection of IgG and IgM antibodies against TP pathogens is feasible, and it has important value for further application in clinical diagnosis.

[Objective] To investigate the effect of SKY expander vertebroplasty and KYPHON vertebroplasty for compression fracture of thoracic/lumbar vertebral body. [Methods] Twenty-one patients (group A) with compression fracture in 27 thoracic/lumbar vertebral bodies were enrolled to this study. Among them, 17 fractured vertebral bodies from 15 patients received SKY expander vertebroplasty and another 10 fractured vertebral bodies from 6 patients received KYPHON vertebroplasty. Thirty-three patients (group B) with compression fracture in 35 thoracic/lumbar vertebral bodies receiving conservative treatment during the same period served as the control. After treatment, the therapeutic effect and result of X-ray image were compared in the two groups. [Results] A follow-up ranging from 1 month to 11 months showed that pain in the loin and back, decrease of vertebral height, complications of leaking of bone cement, and bed sore (which occurred in group B) were not found in the patients receiving vertebroplasty. [Conclusion] SKY expander vertebroplasty and KYPHON vertebroplasty are effective and safe for compression fracture of thoracic/lumbar vertebral body, which can relieve the back and loin pain as soon as possible, reconstruct the vertebral body, decrease the occurrence of complications and promote the rehabilitation, and have a better effect than conservative treatment. For the two kinds of vertebroplasty, SKY expander vertebroplasty is economic and indicated for single vertebral fracture and old fracture, and KYPHON vertebroplasty is indicated for multiple vertebral fracture, severe fracture, and vertebral body fracture with end-plate broken.

As a new model of pre-cancer, organoid is essential for the basic understanding of tumor characteristic and effective tumor treatment. Organoids derived from prostate play an especially important role in the research of fundamental oncology and anticancer drug screen against prostate cancer. Prostate cancer cell lines and xenografts derived directly from primary human tumors are widely used now as models to study prostate cancer and have proven very valuable. But there are some caveats and shortcomes of these two models that have to be accounted for. Here we outline organoid as a third preclini?cal cancer model which may potentially overcome the shortcomes of cancer cell lines and PDTX. This article aims to summa?rizee recent progress of the role of organoid in prostate cancer research.

Objective To evaluate prognostic significance of early lactate clearance rate for cardiogenic shock patients on extracorporeal membrane oxygenation(ECMO).Methods Forty-seven patients with cardiogenic shock supported by venoarterial ECMO were prospectively enrolled from May 2010 to May 2013.Arterial blood lactate at pre-ECMO support(0 h),at post-ECMO 6 hours(6 h) were measured and then 6 h lactate clearance rate was calculated.90 days after admission was the endpoint of research.Patients were divided into the survival group(n =25) and the death group(n =22).6 h lactate clearance rate was compared between groups.The 6 h lactate clearance rate for predicting death was evaluated by receiver operating characteristic(ROC) curves.The surviving curve was drawn using the Kaplan-Meier method,and the survival of the patients was analyzed by the Log-rank test.Factors influencing the prognosis were analyzed by applying the multiplelogistic regression analysis.Results The 6 h lactate clearance rate was higher in survivors than in nonsurvivors [(38.6 ± 15.1) % vs.(14.4 ± 13.8) %,P < 0.05].The area under the ROC curve of 6 h lactate clearance rate for predicting death was 0.869 ± 0.075 (95% CI:0.753-0.991).The best cutoff point was 20.0% with a sensitivity of 92.0% and specificity of 85.0%.KaplanMeier survival analysis showed that 90 days survival rate of high lactate clearance rate group and low lactate clearance rate group were 66.7% and 35.0%,with significant difference between the two groups(Log-rank test,P < 0.05).Multivariate logistic regression analysis showed that 6 h lactate clearance rate (OR =3.156,95 % CI:2.326-7.253,P < 0.05) was one of the independent risk factors associated with mortality of patients on ECMO.Conclusion Early lactate clearance rate could be used as an important maker for evaluating the prognosis of cardiogenic shock patients on ECMO.

Objective To investigate the effects of acarbose versus fenofibrate on insulin secretion and insulin resistance in the subjects with impaired glucose tolerance (IGT) and hypertriglyceridemia. Methods Eighty subjects were allocated to acarbose group (28 cases),fenofibrate group (30 cases),and control group (22 cases) without intervention for 3 months,and also divided into elderly (46 cases) and younger groups (34 cases). Fasting blood samples were collected for measuring fasting plasma glucose and lipid.Oral glucose tolerance test (OGTT) were carried out with measurement of plasma insulin and glucose before ad after treatment.Early insulin secretion indexes(△I30/△G30),insulin secretion indexes (HOMA -β) and insulin resistance indexes (HOMA-IR)were calculated. Results After 3-months of treatment,the lipid profile was evidently improved in fenofibrate group. Levels of triglyceride (TG) and total cholesterol (TC) were significantly reduced ( both P < 0.01 ),△I30/△G30 was significantly increased (P < 0.05) and HOMA-IR was decreased (P<<0.01).In acarbose group,levels of fasting plasma glucose (FPG),2hours postprandial plasma glucose (2 hPG) and HOMA-IR were reduced (all P<0.01),△I30/△G30 and HOMA-β were enhanced (P<0.01 or P<0.05).No change of above indicators was found in the control group.Compared with fenofibrate group,acarbose group had higher △ I30/△G30 (P< 0.05),HOMA-β (P< 0.01 ) and lower HOMA-IR ( P < 0.01 ).The improvement of △△I30/△G30 was correlated with the decreasing of plasma FPG,2 hPG and TG(r=0.5812,0.6327,0.3872,P<0.01),while HOMA-1R was related with the decreasing of plasma 2 hPG,TG and TC(r=0.8126,0.4671,0.2895,P< 0.01). HOMA-IR,△I30/△G30 and HOMA-β were lower (P<0.01) and acarbose improved insulin resistance better (P<0.05) in the elderly than in the younger with type 2 diabetes. Conclusions Pancreatic β-cell function declines gradually with aging,acarbose may have advantage over fenofibrate in improving early insulin secretion and resistance which was more relieved by diminishing glucotoxity in comparison with lipotoxity.

Objective To investigate the therapeutic effect of modulated medium frequency current therapy (MMFCT) combined with infrared therapy on patients of acute facial neuritis. Methods A total of forty-six patients with acute facial neuritis were divided into two groups (observation group and control group) randomly and medially. Every patient received medication. Meanwhile, observation group received MMFCT and infrared therapy. Before the treatment, and after two and four weeks of treatment, Portmann scale were used to evaluate the autonomic movements of the facial expression muscles on both sides. After 4 weeks of treatment, the outcome was evaluated by House-Brackmann facial nerve grading system. Results There were no significant differences in Portmann scales before treatment between two groups. Portmann scales were higher in observation group than those of control group after two and four weeks of treatment (P<0.05). With the duration of treatment, Portmann scales were increased successively in two groups. The significant difference was found in multiple comparisons between groups. After 4 weeks of treatment, the efficacy was significant in the observation group, compared with control group, the difference was significant (P<0.05). Conclusion Modulated medium frequency current therapy combined with infrared therapy have a better effect than isolated medication.
