Objective: To research the method of Establishing model of polymyositis with damp-heat syndrome. Methods: 45 guinea pigs were randomly divided into three groups, group A (normal group), group B (experimental myositis group, control group), Group C (damp-heat group). In the control group, the rabbit skeletal muscle homogenate Garver,s complete adjuvant for subcutaneous immunization was used to injecting into the original guinea pigs. Besides the above-mentioned immune method, the heat-damp model method was used (feigan diet, hot and humid environment and pathogenic micro-organisms and other complex factors) to establish the polymyositis model with damp-heat syndrome. The general situations, such as the serum muscle enzymes, light microscopy, electron microscopy changes in each group were observed. Results: The results showed that the clinical performance, serum creatase, the pathological changes of skeletal muscle, lungs, liver of guinea pigs in damp-heat group were similar to the human polymyositis with damp-heat syndrome. Conclusion: The model can be used to study the human polymyositis with damp-heat syndrome, and provide the pathogenic and theoretical basis for treating polymyositis by TCM.

Objective To investigate the changes of traditional Chinese medical constitution types with menstrual cycle of sub-health state women, thus to explore the affectability of diseases during menstrual cycle. Methods Sub-health State Questionnaire and Menstruation State Questionnaire established in our previous study were used for the epidemiological survey of 330 women outpatients aged 20-45 years admitted by the disease-preventive department of Tianhe District Hospital of Traditional Chinese Medicine. Results In 330 cases, the cases of sub-health state accounted for 64.5%, in which 21.5%had pure sub-health state without any chronic diseases, and 43.0% had sub-health state together with some diseases. The diseases of hyperplasia of mammary glands, vaginitis, cervical spondylosis, hyperlipemia, chronic appendagitis, and uterus myoma had higher morbidity rate in order. At premenstrual phase, constitution types of Qi stagnation, damp heat, and blood stasis had the higher incidences; at menstruation phase, Qi stagnation, blood stasis, and damp heat had the higher incidences; at postmenstrual phase, yang deficiency, Qi deficiency, and damp heat had the higher incidences. Most of the sub-health state women had the complex constitution types, accounting for 93%. Conclusion Traditional Chinese medical constitution types are correlated with menstral cycle of sub-health state women, and show some effects on the affectability and progress of diseases. The investigation results of dynamic changes and the distribution of traditional Chinese medical constitution types during menstrual cycle will supply some evidence for the prevention and treatment of irregular menstruation and sub-health state of the women with Chinese medine.

ObjectiveTo investigate the influence of Mycobacterium tuberculosis (MTB) co-infection and other factors on the HIV replication level in antiretroviral treatment na(i)ve patients.MethodsSix hundred TB patients and 465 HIV infectors were recruited between April 2010 and September 2010.TB coinfections were diagnosed in HIV infected cases with chest X-ray,checking TB in sputum with anti-acid staining and culture of the sputum,histopatholo diagnosis and clinical diagnosis.HIV infections were screened in TB patients with the 3rd generation ELISA antibody test.Sixty-one antiretroviral treatment na(i)ve HIV/TB co-infectors and 34 HIV infectors with CD4 T cell count below 350 cells/μl were included in this study.Information about the demography,epidemiology and results of clinical diagnostic tests of HIV and TB was collected through pathography and questionnaires from all participants.HIV viral load were detected with COBAS AmpliPrep/COBAS TaqMan(R) System of Roche Company.ResultsThe viral load of HIV/TB co-infectors was (5.05±0.93) lg copies/ml,while the viral load of HIV infectors was (5.06±0.76) lg copies/ml,after control of age,race,marital status,education,route of HIV infection,HIV clade and CD4 T cell count,there was no significant difference between the two groups (P=0.94).CRF01_AE HIV-1 infection was associated with higher HIV viral load compared with non CRF01_AE (OR=8.07,95％ CI 1.07-61.20,P=0.04).ConclusionNo obvious effect of MTB co-infection on HIV replication level of HIV infected cases with relatively low CD4 T cell count in Guangxi region,while the CRF01_AE HIV infected individuals showed higher viral load,we should raise concern on the monitoring and treatment on this population.

Objective To investigate the correlation between single nucleotide polymorphisms (SNPs) of FOXP3 gene and the susceptibility of hepatocellular carcinoma (HCC). Methods Two SNPs rs2280883 and rs3761549 of FOXP3 gene in 392 HCC patients and 372 healthy controls were analyzed by Matrix-Assisted Laser Desorption/ Ionization Time of Flight Mass Spectrometry (MALDI-TOF).Results At rs3761549,C allele frequency was significantly higher ( OR =1.32,95％ CI 1.03 -1.70,P =0.027) in HCC patients than healthy controls.Compared with healthy controls,HCC patients had higher frequencies of TT genotype (79.6％ ) at rs2280883 or CC genotype (77.6％) at rs3761549 of FOXP3 gene.Patients carrying rs2280883 TT genotype ( OR =1.53,95％ CI 1.10 - 2.14,P ＜ 0.00001 ) or rs3761549 CC genotype ( OR =1.92,95％ CI 1.39 - 2.64,P ＜ 0.00001 ) were more susceptible to HCC.Stratified analysis showed that rs3761549 CC genotype was significantly associated with higher incidence of portal vein tumor thrombus ( x2 =5.578,P =0.018 ),and rs3761549 TT/CT genotype was significantly associated with higher rate of tumor recurrence in HCC patients (x2 =6.561,P =0.010).Conclusions FOXP3 gene polymorphisms at rs2280883 and rs3761549 might be associated with increased susceptibility to HCC. rs3761549,CC genotype and TT/CT genotype were respectively associated with higher incidence of portal vein tumor thrombus and tumor recurrence in HCC patients.

Cough is one of the most common symptoms of many respiratory diseases; the characteristics of intensity and frequency of cough sound offer important clinical messages. When using these messages, we have need to differentiate the cough sound from the other sounds such as speech voice, throat clearing sound and nose clearing sound. In this paper, based on Empirical Mode Decomposition (EMD) and Hidden Markov Model (HMM), we proposed a novel method to analyze and detect cough sound. Employing the property of adaptive dyadic filter banks of EMD, we gained the mean energy distribution in the frequency domain of the signals in order to analyze the statistical characteristics of cough sound and of other sounds not accompanied by cough, and then we found the optimal characteristics for the recognition using HMM. The experiments on clinical date showed that this optimal characteristic method effectively improved the detective rate of cough sound.

Objective: To investigate the impact of hepatoprotective drugs on the performance of APRI for diagnosing liver fibrosis in chronic hepatitis B (CHB). Methods: Patients with CHB who underwent a percutaneous liver biopsy were recruited and divided into hepatoprotective drugs using group and hepatoprotective drugs free group. Grouping was carried out according to the types of commonly used hepatoprotective drugs, and controls were matched for each groups by stage of liver fibrosis and age from hepatoprotective drugs free group. The performance of APRI for diagnosing significant fibrosis and cirrhosis was evaluated and compared between each experimental groups and control groups using receiver operating characteristic (ROC) curves. Results: A total of 1447 patients were enrolled, including 60 using glycyrrhizin, 54 using silymarin, 63 using traditional Chinese medicine (TCM) containing schisandra, and 113 using more than one hepatoprotective drug. In patients using glycyrrhizin, the sensitivity of APRI to predict significant fibrosis was higher than its control group. In patients using more than one hepatoprotective drug, the sensitivity of APRI to exclude significant fibrosis was higher than its control group; the area under ROC curve of APRI to diagnose significant fibrosis, the specificity of APRI to exclude and predict significant fibrosis were all lower than its control group. In patients using glycyrrhizin and patients using more than one hepatoprotective drug, the specificity of APRI to exclude cirrhosis were both lower than their control groups. In patients using silymarin and patients using TCM, the performance of APRI to diagnose significant fibrosis and cirrhosis was comparable with their control groups. Conclusions Glycyrrhizin and combination of hepatoprotective drugs would have significant impact on the performance of APRI for diagnosing liver fibrosis in CHB, silymarin and TCM containing schisandra would have less impact.
