Balantidiosis is a disease infected with Balantidium coli,and swine is the main infection source. The infection of B. coli may cause diarrhea,extra intestinal infection and co?infection with other pathogens and even intestinal necrosis. Strength?ening the manure management of both human and livestock,paying attention to personal hygiene and labor protection,and time?ly treatment of the patients are the main measures to control balantidiosis.

Objective To investigate the association of plasma metallothionein 3 (MT3) and its polymorphisms with childhood autism,in order to provide the objective evidence for autistic etiology and molecular diagnosis.Methods A total of 132 autistic children were recruited from several special autism training schools in Wuhan and the Hubei Maternal and Child Health Hospital between January 2011 and November 2014.Three hundred and sixteen healthy children from the out-patients of Zhongnan Hospital of Wuhan University during the same period were enrolled as healthy controls.Enzyme linked immunosorbent assay was utilized to measure plasma MT3 protein levels in a dataset of 81 cases and 80 controls,while eight single nucleotide polymorphisms (SNP) located in MT3 gene were genotyped in another greater dataset that included 132 cases and 236 controls by the matrix-assisted laser desorption/ionization time of flight mass spectrometry within the Sequenom platform.Results Plasma MT3 protein level was significantly lower in autistic group compared to healthy controls [(740.0 ± 327.4) ng/L vs (1 007.1 ± 554.3) ng/L,P ＜ 0.001],particularly for boys when stratified by gender (P =0.005).No difference existed in any allele or genotype frequencies between the 2 groups (all P ＞ 0.05).Conclusions The selected autistic children harbored abnormal expression profiles of plasma MT3 protein,which may have no connection with its gene polymorphisms.

Objective: To observe the efficacy of contralateral needling combined with Maitland ankle mobilization in the treatment of chronic ankle sprain.Methods: A total of 106 patients with chronic ankle sprain were included in the study. They were numbered according to their order of visit, with odd numbers assigned to the control group and even numbers assigned to the observation group, with 53 cases in each group. Patients in the control group were treated with Maitland ankle mobilization, while those in the observation group were given additional contralateral needling treatment. After treatment, we observed the indicators including, ankle circumference, range of motion (ROM) of dorsiflexion, ROM of plantar flexion, thickness of ankle ligaments, and the changes in Baird-Jackson ankle score, American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, and visual analog scale (VAS) score to compare the efficacy between the two groups. Results: After treatment, the total effective rate of the observation group was 94.3％ and was significantly higher than that of the control group (81.1％), indicating statistical significance (P<0.05). After treatment, the ankle circumference of both groups decreased, and the ROM of dorsiflexion and the ROM of plantar flexion increased (P<0.05). The changes in the observation group were more significant, indicating inter-group statistical significance (P<0.05). After treatment, the thickness of the anterior talofibular ligament, calcaneofibular ligament, and posterior talofibular ligament, as well as the VAS scores decreased in both groups; the changes in the observation group were more significant, indicating inter-group statistical significance (P<0.05). After treatment, the Baird-Jackson ankle score and the AOFAS ankle- hindfoot score increased in both groups, and the scores in the observation group were higher than those in the control group, indicating inter-group statistical significance (P<0.05). Conclusion: The efficacy of contralateral needling combined with Maitland ankle mobilization in the treatment of chronic ankle sprain is superior to that of Maitland ankle mobilization alone.

Objective To evaluate the clinical diagnostic significance of clinical laboratory indexes of anti-CCP,rheumatoid factor (RF),C reactive protein(CRP)and erythrocyte sedimentation rate(SR)in rheumatoid arthritis.Methods Anti-CCP,RF and CRP were quantitatively tested in 90 patients confirmed as rheumatoid arthritis(RA)and 93 patients with non-rheumatoid arthritis(non-RA)diseases by the electrochemiluminescence immunoassay(ECLIA),immunization rate scattering turbidimetry,etc.T test results were performed the statistical and comprehensive analysis by using the ROC curves.Results The levels of anti-CCP and RF had statistical differences between the RA group and the non-RA group(P <0.05 ),while there was no statistically significant differ-ences in the levels of CRP and SR(P >0.05 ).The areas under ROC curves(AUC)of anti-CCP,RF,CRP and SR were 94.0%, 84.0%,51.7% and 56.5% respectively;the sensitivity of anti-CCP and RF was 90.0% and 74.4% respectively,while the specifici-ty was 94.6% and 86% respectively;the Youden indexes were 84.6%and 60.4% respectively;the diagnostic sensitivity of CRP was only 52.2% and the diagnostic specificity of SR was only 50.5%.Conclusion Anti-CCP and RF have the good diagnostic value for RA,moreover the diagnostic performance of anti-CCP is better than RF;CRP and SR have the poor diagnostic preformance,the combination of above indexes has more clinical significance for diagnosing RA.

OBJECTIVEThrough a simulation of interstitial fluid pressure (IFP), we developed an in vitro model to explore the change law of biological characteristics of adenoid cystic carcinoma (ACC) under different IFP.

METHODSA pressure cooker was refitted into a controllable pressure device. Cultured ACC-2 cells were subdivided into different groups, namely, negative control (untreated ACC-2) and experimental group (stressed for 3, 6, 12, 24 h under pressure of 7.551, 7.649, 7.747 kPa). CCK-8 and immunofluorescence of Ki67 were used to reflect proliferation ability. Transwell chamber assay was performed to observe the invasion ability of cells.

RESULTSThe proliferation ability was positively correlated with treatment time, and the peak value was obtained after the cells were subjected to 7.649 kPa of stress for 24 h. The invasion ability of ACC-2 cells was upregulated under stress.

CONCLUSIONWe successfully developed an in vitro model of IFP and found that high IFP can stimulate cell proliferation ability and upregulate invasion ability.

Objective To investigate the efficacy of progressive resistance exercise for improving the lower limb motor function of hemiplegic stroke patients. Methods Eighty-nine hemiplegic patients were randomly divided into a treatment group (n =46) and a control group ( n = 43 ) . Both groups received routine rehabilitation training, while the treatment group also undertook progressive resistance training. The control group received extra quadriceps femoris training. Before and after the treatment, motor function was evaluated with the Fugl-Meyer lower limb assessment, functional ambulation category (FAC) classification and the modified Barthel index (MBI). Results Before intervention, there were no significant differences between the two groups in any of the assessments. Four weeks later, all the assessment scores obtained with the Fugl-Meyer lower limb assessment, FCA classification and MBI in the treatment group were significantly better than those in the control group. Conclusion Progressive resistance training combined with routine rehabilitation treatment can improve motor function in the lower limbs, ambulation and ability in the activities of daily living of hemiplegic patients after stroke.
