ABSTRACT
Objective To observe the short-term effect of Paris polyphylla Smith var. yunnanensis powder combined with anti-tuberculosis drugs in the observation of superficial lymph node tuberculosis. Methods A total of 170 patients were randomly divided into two groups: 80 in the control group and 90 in the observation group. The observation group consisted of nodular type, infiltrating type and abscess type, each of which had 30 cases. The control group were treated with Isoniazid, Rifampicin, Pyrazinamide and Ethambutol. Besides the four medications, the observation group were treated with external application of Paris polyphylla Smith var. yunnanensis. Results The response rate was 30.00％in the control group and 64.44％in the observation group. The response rate in the observation group was higher than that in the control group, with a statistically significant difference ( <0.01). In the observation group, the response rates of abscess, infiltration and nodule were 76.67％, 73.33％and 43.33％, respectively.By the comparative analysis, the response rate of infiltration was higher than that of nodule ( <0.05), with a significant difference; the response rate of abscess was also higher than that of nodule ( <0.05), with a significant difference. There was no significant difference between the response rates of abscess and infiltration ( >0.5) .Conclusions The external application of Paris polyphylla Smith var. yunnanensis powder combined with anti-tuberculosis drugs is curative in the observation of superficial lymph node tuberculosis, especially in the types ofinfiltrating and abscess.
ABSTRACT
<p><b>OBJECTIVE</b>To describe the clinical and epidemiological features of dead cases with human Streptococcus suis infections, and to find the target population for preventing death and the related indicators.</p><p><b>METHODS</b>Epidemiological investigation on human Streptococcus suis infections was implemented used unified questionnaires. Analysis on dead cases and survival cases (as contrast) was done.</p><p><b>RESULTS</b>The population with highest fatality rate was in 40-49 age group. 97.37% of dead cases had toxic shock syndrome. The mean interval from onset to admission was 0.76 days, and the mean course was 2.11 days. The progression among dead cases was faster than that among survival cases. Chief clinical manifestations of dead cases that are more frequent than survival cases are purpura (73.68%), diarrhea (50.0%), dyspnea (21.05%), conjunctival congestion (34.21%), etc. Renal impairment and liver involvement in dead cases were more significant than that in survival cases. No significant difference between mean incubation period, exposure rates of main risk factors in dead cases and in survival cases was found.</p><p><b>CONCLUSION</b>Preventing toxic shock syndrome might reduce the fatality rate. The target population for preventing death is aged > or = 40. Liver function and renal function testing might be indicators for monitoring the progression of human Streptococcus suis infections.</p>

<p><b>OBJECTIVE</b>To study the potential risk factors of human infecting with Streptococcus suis.</p><p><b>METHODS</b>1: M matched case-control study was conducted. 29 human cases of Streptococcus suis infection in the early phase were included in the case group, Patients' family members, neighbors and peoples who had worked together with patients to handle deceased or sick pigs in the last week were recruited as matched controls. There were 147 controls in total. Both cases and controls received questionnaire investigation including the ways to contact sick/dead pigs. Conditional logistic regression was employed to analyze matching data.</p><p><b>RESULTS</b>According to the results of multivariate analysis, slaughtering (OR = 11.978, 95% CI: 3.355-42.756), carcasses cutting and processing (OR = 3.008, 95% CI: 1.022-8.849) sick/dead pigs were associated with cases related to human Streptococcus suis infection. The attributable risk proportion were 91.65% and 66.76% respectively. The other types of exposures to sick/ dead pigs, including feeding, selling, burying and eating, were not associated with the human Streptococcus suis infection in our study population.</p><p><b>CONCLUSION</b>Slaughtering, carcasses cutting and processing sick/dead pigs were important risky behavior for humans to be infected by Streptococcus suis.</p>
