Analysis on Mechanical Characteristics of Lin’s Lumbar Vertebral Manipulation by Lifting-Rotating and Oblique-Pulling / 医用生物力学

Objective To study the mechanical characteristics of lumbar vertebral manipulation by lifting-rotating and oblique-pulling using multi-film pressure measurement system. Methods Twenty-one male operators were divided into groups of experts, skilled operators and beginners. Everyone completed 7 actions of Lin’s lumbar manipulation continuously, and repeated 3 times. The graphs and data were collected and processed. Results The time-force curve by the experts had regularity. The average pre-load force was (147.25±26.04) N, duration was (0.98±0.20) s, the average minimum force was (79.22±9.50) N, the maximum impact force was (706.26±56.21) N, the flip time was (0.44±0.09) s, and flip speed was (1 666.33±411.91) N/s, the impulse was (310.95±56.67) N·s. The curve graphs and the index by the skilled operators were similar to those by the experts, but the average maximum impact force was (464.51±53.49) N, which was relatively smaller. The curve graphs by the beginners could be broadly divided into three categories. Class Ⅰ was chaotic and unregulated; Class Ⅱ only had impact force and did not have pre-load force, and the maximum impact force varied in size; Class Ⅲ had both impact force and pre-load force, but the forces were relatively small and stable. Conclusions The multi-film pressure measurement system can preferably display the mechanical characteristics of manipulation by lifting-rotating and oblique-pulling, which is an ideal testing tool for quantitative research on mechanical parameters of Lin’s lumbar vertebral manipulation. The experimental results provide a scientific basis for visualization, quantification and standardization of the manipulation.

Analysis of influencing factors of portal vein tumor thrombus in primary liver cancer / 肿瘤研究与临床

Objective To investigate the influencing factors of portal vein tumor thrombus in patients with primary liver cancer(PLC).Methods A total of 483 patients with PLC in the Second People's Hospital of Fuyang from January 2012 to December 2016 were included in this retrospective study.Univariate analysis and multi-variate logistic regression analysis were employed to analyze the association between portal vein tumor thrombus and routine clinical parameters.Results The univariate analysis showed that alanine aminotransferase,aspartate aminotransferase,total bilirubin,γ-glutamyltranspeptidase,alkaline phosphatase,alpha-fetoprotein,the size and the number of tumors,ascites and center location of cancer performed a close relationship with the formation of portal vein tumor thrombus in patients with PLC,and the differences were statistically significant(P values were 0.010,0.000,0.010,0.000,0.001,0.000,0.000,0.004 and 0.010).Multivariate logistic regression analysis showed that potential significant predictors of portal vein tumor thrombus in patients with PLC were alpha-fetoprotein and ascites,and the differences were statistically significant(P values were 0.000 and 0.040).Conclusion PLC patients with high level of alpha-fetoprotein and ascites are easier to induce the formation of portal vein tumor thrombus.

Combined detection of immunobiological markers in pleural or peritoneal exudates of patients with tuberculosis and malignant tumors / 中华全科医师杂志

The levels of C-reactive protein(CRP),adenosine deaminase(ADA),total cholesterol (TC),lactate dehydrogenase(LDH),carcinoembryonic antigen(CEA),ferritin(Fer),β2-microglobulin (β2-MG),alpha-fetoprotdn(AFP),carbohydrate anfigen12-5(CA125),carbohydrate antigen19-9(CAl99),carbohydrate antigen15-3(CA153),eyfra211(CY211)and neuron specific enolase(NSE)were detected by automatic chemistry analyzer or electrogenerated chemiluminescence analyzer in pleural and peritoneal exudates from 48 cases oftuberculosis and 82 cases of malignant tumors.The levels of CRP,ADA and β2-MG in tuberculotic exudates were higher than those in malignant exudates(P<0.01).However,the levels of TC,LDH,CEA,Fer,CA153,CY211,NSE,AFP,CA125 and CA199 in malignant exudates were higher than those in tuberculotic exudates(P<0.01).Combined determination of CRP,ADA,TC,LDH,CEA,Fer,and β2-MG in pleural and peritoneal exudates are of value in differentiation of tuberculosis from malignant exudates.Combined determination of CA153.CY211 and NSE in pleural effusions and AFP,CA125 and CA199 in peritoneal effusions can improve the semitivity and specificity of diagnosis for malignant exudates.

T lymphocyte sub-populations in malignant and tuberculous pleural effusion or ascites / 中华全科医师杂志

Objective To determine counts of T lymphocyte sub-populations in malignant and tuberculous pleural effusion or ascites and evaluate its significance in difierential diagnosis.Methods T lymphocyte sub-populations in pleural effusion or ascites and peripheral blood were determined in 30 patients with tuberculosis and 31 patients with cancer by flow cytometry.Concentrations of cytokines Th1 and Th2,γ-interferon(IFN-γ),interleukin-12(IL-12)and IL-4 in pleural effusion or ascites were measured by enzyme-linked immunosorbent assay(ELISA).Results Compared to that in peripheral blood,percentage of CD3+ and CD4+ T-celI counts were all higher in both malignant and tuberculous pleural effusion or ascites [(73±6)%and(67±20)%vs.(51±19)%and(48±14)%,P＜0.05].Although CD3+T-cells count was higher in tuberculous pleural effusions or ascites,no difference in ratio of CD3+ and CD4+/CD3+ and CD8+ T-cell counts was found between malignant and tuberculous pleural effusions or ascites.However,ratios of IFN-γ and IL-12 to IL-4 were higher in tuberculous pleural effusion or ascites(54±24 and 82±19vs.8±6 and 19±10,t=10.34 and 16.28,respectively,P＜0.01).Conclusions CD3+ and CD4+ Tcells can be aggregated in both malignant and tuberculous pleural effusions or ascites,80 nature (tuberculosis or malignancy)of pleural effusion or ascites can not be differentiated by CD4+ and/or CD8+ T-cell counts only,and determination of cytokines Th1 and Th2 can help their differentiation.

Three-stage swallowing rehabilitation for stroke patients with dysphagia / 中华物理医学与康复杂志

Objective To explore the effects of three- stage swallowing rehabilitation on the swallowing a-bility of stroke patients with dysphagia. Methods 60 stroke patients were divided into primary cerebral infarction and primary cerebral hemorrhage groups, then further divided into treated and control groups randomly. All groups were given the same routine internal medicine treatment. Patients in the treated group were given three stage swallo-wing rehabilitation training additionally. All patients were assessed using Caiteng's Grading Method at the outset and at the end of the 2nd week, the Ist month and the 2nd month. Results Swallowing function scores in the treated groups were higher than those in the control groups at every stage (P≤0.05). The treated groups' scores also im-proved more quickly than those in the control groups. Conclusion Three stage swallowing rehabilitation can signifi-cantly improve stroke patients' swallowing function.
