Objective To explore the effect of Chaihu Shugan Powder (CSP) on the content of 5-hydroxytryptamine (5-HT) in the hippocampus and the expression of tryptophan hydroxylase 2(TPH2) in median raphe nuclei in depression rats.Methods SD rats were randomly divided into normal group(n=12),model group (n=12),fluoxetine group (n=12),low-dose and high-dose CSP group (n =12,respectively).Depression model was made by reserpine intraperitoneal injection.During the experiment,the weight and the open-field scores were calculated;the content of 5-HT was detected by ELISA.The expression of TPH2 in median raphe nuclei was detected by Western blot.Results Compared with the weight ((225.02±5.23) g),the open-field scores ((12.6± 5.1)score) and content of 5-HT ((1.09±0.27) ng/ml) in the model group,high-dose CSP showed significantly improve the depressive rats in weight,open field score and content of 5-HT ((238.78±5.16) g,(15.6±7.8) score and (1.80±0.58) ng/ml,respectively;P＜0.05 or P＜0.01).The expression of TPH2 (0.66±0.21) in median raphe nuclei in the high-dose CSP group was apparently increased compared with that in the model group(0.16±0.04) (P ＜0.01).Conclusion CSP have the effects of anti-depression,which could be related with the increase of the 5-HT content in the hippocampus and the expression of TPH2 in median raphe nuclei.

Objective To assess the damage of limbic system pathways in relapsing-remitting multiple sclerosis (RRMS) by diffusion tensor imaging (DTI) tractography.Methods DTI tractography was used to acquire fiber numbers,fractional anisotropy (FA),mean diffusivity (MD) of cingulum,fornix,and uncinate fasciculus (UF) in 20 RRMS patients (MS group) and 20 healthy volunteers (control group),and statistical analysis was performed.Results Compared with control group,lower FA value (P＜0.01) and higher MD value (P＜0.05) were found in cingulum,fornix and UF of MS group,and the fiber numbers of fornix decreased in MS group (P＜0.001).There were significant differences between the left and the right UF in fiber numbers and FA value of control group and the fiber numbers of MS group.Negative correlations were found between FA value of cingulum and UF and EDSS scores in MS group (r=-0.572,-0.665,both P＜0.05),and positive correlations were found between MD value and EDSS scores (r=0.627,0.603,both P＜0.05).Conclusion DTI tractography is valuable in assessing MS associated limbic system damage and in monitoring the clinical progression of the disease.

Purpose Intravoxel incoherent motion (IVIM) MR is a method developed in recent years which can quantitatively evaluate the diffusion and perfusion characteristics of microenvironment.The aim of this study was to investigate the application value of IVIM in assessing relapsing-remitting multiple sclerosis (RRMS).Materials and Methods A retrospective analysis of the clinical data of 27 patients with RRMS confirmed clinically at the First Affiliated Hospital of Chongqing Medical University from Jun.2015 to Jan.2016 was carried out in the study.All the patients underwent the conventional MRI and IVIM MRI based on multi-b-factor (b values of 10,20,30,40,50,100,150,200,350,500,650,800,1000 s/mm2) with 3.0T MR scanner.The apparent diffusion coefficient (ADC),ADCslow,ADCfast and f values were evaluated since they could reflect the diffusion and perfusion status of RRMS lesions and normal-appearing white matter (NAWM) regions.Results The ADC,ADCslow,ADCfast and f values of the non-enhancing (NE) lesions were significantly higher than those in the NAWM regions both near and far from NE lesions (P＜0.05).However,the ADC,ADCslow,ADCfast and f values in the NAWM regions close to the NE lesions had no significant differences with those in the NAWM regions far from the lesions (P＞0.05).Conclusion The IVIM MRI can measure the diffusion and perfusion status of the lesions and NAWM in RRMS patients,which,therefore,is helpful in speculation of the pathological changes of RRMS lesions and in its injury classification and identification.

Objectives To compare clinical manifestations and electrophysiological features in patients with chron?ic inflammatory demyelinating polyneuropathy (CIDP) and Type-I Charcot Marie Tooth Disease (CMT-I) for guiding dif?ferential diagnosis. Methods Data including clinical manifestations and electrophysiological indexes was collected from thirty-one CIDP cases and 28 CMT-I cases. Correlation analysis was used to assess the association of the severity of electrophysiology with the severity of clinical symptoms. Results There were statistically significant differences in onset site, sensory dysfunction, foot deformity and cerebrospinal fluid protein between these two groups (P<0.05). There were significant differences in indexes of nerve conduction and needle electromyography between these two groups (P<0.05). The severity of clinical symptoms was not related with the severity of electrophysiology in CMT-I group (r=0.27,P>0.05). Conclusions Differential diagnoses of CIDP and CMT-I can be made based on clinical manifestations and electro?physiological features.

Objective To investigate the infection status of HIV/AIDS patients complicated with pneumocystis Carinii Poneumonia(PCP),and the role of CD4+ T lymphocyte in PCP.Methods PC was detected by Giemsa's staining and CD4+ T lymphocyte was counted by flow cytometry.Meanwhile,this text calculated and compared a series of indexes about PC infection,such as the total positive rate,the average annual positive rate,the average monthly positive rate,the positive rate between female and male,the positive rate between sputum and BALF specimens,and the relationship between the positive rate and CD4+ T lymphocyte count.Results The total positive rate about PC infection of the 1 806 eases of sputum specimens was 46.8％,and the incidence mainly from April to July during a year,and the positive rates were 46.3％ and 50.2％ for males and females respectively.The results showed that there were no significant differences when compared with the average annual positive rate ( P ＞ 0.05 ),but there were significant differences when compared with the average monthly positive rate ( P ＜ 0.05 ),the positive rate between female and male(P＞0.05),and among 3 formerly defined ranges of CD4+count(P ＜0.05).Conclusion Giemsa's staining showed the total positive rate was 46.8％ of the HIV/AIDS patients infected by PC with sputum specimens,which represented a seasonal fluctuation tendency.The positive rate of BALF was higher than that in sputum,and it increased with CD4+ count decreasing.Giemsa's staining was an efficient,simple and feasible way for PC detection and easy for generalization.Meanwhile,it is strongly relied on the operator's experience and skill.

Objective To explore the applications of case analysis learning and traditional teaching method in clinical practice teaching effect for students majoring rehabilitation therapy in the course of musculoskeletal rehabilitation.Methods 83 program students of Rehabitation Therapeutics in grade 2011 were chosen to participate in the clinical practice teaching in the course of musculoskeletal rehabilitation of 12 credit hours.Class 1 was taught by the traditional teaching method,while Class 2 was taught by the case analysis learning,making clinical case analysis,practical operation and case discussion working as teams.After learning,we made an analysis of two classes through the form of theory examination,practical operation and the questionnaire.The evaluation scores were shown by (x ± s)and comparison was made between the two groups with t test after SPSS software for statistical analysis.Results Taught by the case analysis,the theoretical performance of Class 2 was (83.37 ± 5.59),better than Class 1 (80.85 ± 6.98),but the difference was not statistically significant (P=0.056),but in the practice operation the achievements of Class 2 were (72.65 ± 8.05) points better than Class 1 (66.49 ± 12.86),and the difference was statistically significant(P=0.024).The survey results showed that in Class 2 which adopted case analysis teaching,students' satisfaction was higher than that of Class 1 which kept traditional teaching,and the difference was statistically significant(P＜0.05).Conclusion Case analysis teaching in musculoskeletal rehabilitation application effect is better than the traditional teaching in clinical practice teaching and can be extended to other clinical teaching of rehabilitation therapy specialty.

OBJECTIVE: To investigate the clinical and genetical characteristics of a Chinese family with an autosomal-dominant inherited high-frequency sensorineural hearing loss. METHOD: Pedigree was drawn after investigation. Fifeteen family members were checked up, and detailed audiological examination was performed. RESULT: The proband of the kindred had been diagnosed with senserineural hearing loss. A Chinese family SX-G087 with non-sysdromic hearing loss was ascertained. The inheritance pattern of this family is autosomal dominant based on the investigated information. The affected members showed postlingual, progressive, bilateral moderate to severe sensorineural hearing impairment. The age of onset varied from 20 to 35 years. The hearing loss began at high frequencies, and lower frequencies became involved with increasing age. CONCLUSION Pedigree analysis suggested an autosomal-dominant inheritance pattern in this family. The information should facilitate linkage analysis and positional cloning for the causative gene of this family.

Objective:To validate the feasibility of a deep learning-based clinical target volume (CTV) auto-segmentation algorithm for cervical cancer in clinical settings.Methods:CT data sets from 535 cervical cancer patients were collected. CTVs were delineated according to RTOG and JCOG guidelines, reviewed by experts, and then used as reference contours for training (definitive 177, post-operative 302) and test (definitive 23, post-operative 33). Four definitive and 6 post-operative cases were randomly selected from the testing cohort to be manually delineated by junior, intermediate, senior doctors, respectively. Dice coefficient (DSC), mean surface distance (MSD) and Hausdorff distance (HD) were used for test and comparison between auto-segmentation and RO delineation. Meantime, auto-segmentation time and manual delineation time were recorded.Results:Auto-segmentation models of dCTV 1, dCTV 2 and pCTV 1 were trained with VB-Net and showed good agreement with reference contours in the testing cohorts (DSC, 0.88, 0.70, 0.86 mm; MSD, 1.32, 2.42, 1.15 mm; HD, 21.6, 22.4, 20.8 mm). For dCTV 1, the difference between auto-segmentation and all three groups of doctors was not significant ( P>0.05). For dCTV 2 and pCTV 1, auto-segmentation was better than the junior and intermediate doctors (both P<0.05). Auto-segmentation time consumption was considerably shorter than that of manual delineation. Conclusions:Deep learning-based CTV auto-segmentation algorithm for cervical cancer achieves comparable accuracy to manual delineation of senior doctors. Clinical application of the algorithm can contribute to shortening doctors′ manual delineation time and improving clinical efficiency. Furthermore, it may serve as a guide for junior doctors to improve the consistency and accuracy of cervical cancer CTV delineation in clinical practice.

Objective To assess the changes of white matter microstructure in neuromyelitis optica spectrum disorders (NMOSD) with DTI based on tract-based spatial statistics (TBSS) method.Methods Conventional MR and DTI were performed in 20 NMOSD patients (NMOSD group) and 20 healthy volunteers (control group).DTI data were analyzed with TBSS procedure,which was a part of FSL software packages,and non-parametric statistical analysis was performed on the whole brain.Correlation between FA value of tracts with significant difference in NMOSD group and expanded disability status scale (EDSS) scores was analyzed.Results TBSS analysis revealed significantly (P＜ 0.05,FWE corrected) extensive decrease of FA value in cerebrum and cerebellum white matter fiber bundles,i.e.corpus callosum,fornix,corticospinal tract,unciform fasciculus,cerebellar peduncles etc.in NMOSD group,and decrease of AD value,increase of RD value in cingulum bundle,corpus callosum and fornix,while MD value only increased in fornix and retrolenticular part of the left internal capsule (P＜0.05,FWE corrected).Negative correlations were found between FA value of left uncinate fasciculus,right external capsule,left inferior cerebellar peduncle,bilateral anterior limb of internal capsule,medial lemniscus and EDSS scores (all P＜0.05).Conclusion Widespread white matter damage is observed in cerebrum and cerebellum in NMOSD patients by using TBSS analysis,which may partly correspond to the disabilities of NMOSD patients.However,the other microstructural changes of white matter tracts may suggest complicated pathological mechanism of NMOSD.
