Efficacy and Mechanism of Qingre Lishi Prescription in Treating Children with Acute Bacterial Lower Urinary Tract Infection of Bladder Damp-heat Syndrome / 中国实验方剂学杂志

Objective:To observe the efficacy of Qingre Lishi prescription in treating children with acute bacterial lower urinary tract infection of bladder damp-heat syndrome， and to explore its mechanism of action. Method:Eighty children with acute bacterial lower urinary tract infection of late bladder damp-heat syndrome who were admitted to the Affiliated Hospital of Changchun University of Chinese Medicine were divided into control group and observation group， 40 cases in each group. Patients in control group were given Bazhengsan for oral treatment on basis of basic treatment， while patients in observation group were given Qingre Lishi prescription for oral administration plus external washing treatment. After two weeks of treatment， the clinical and etiological effect， traditional Chinese medicine （TCM） syndrome scores， antipyretic time and urinary negative time， adverse reactions， and urine pathogens （<italic>Escherichia coli， Enterococcus faecalis， Strange proteus， Klebsiella pneumoniae</italic>）， serum inflammatory factor indicators ［tumor necrosis factor-<italic>α</italic> （TNF-<italic>α</italic>）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， calcium lowering PCT， white blood cell count （WBC） and serum C-reactive protein （CRP）］， immune function indicators ［T cell subsets （CD3⁺， CD4⁺， CD8⁺） and complement （C3， C4）］ were comapred between two groups. Result:The clinical efficacy of observation group was 92.50% （37/40）， which was significantly higher than 65.00% （26/40） in control group （<italic>χ²</italic>=9.038， <italic>P</italic><0.01）， the etiological efficacy of observation group was 87.50% （35/40）， which was significantly higher than 60.00% （24/40） in control group （<italic>χ²</italic>=7.813， <italic>P</italic><0.01）. After treatment， the scores of TCM syndromes of the two groups were significantly reduced （<italic>P</italic><0.05）. The scores of fever， frequent urination， urgent urination， painful urination， difficulty urinating and abdominal pain in two groups were significantly lower than those before treatment （<italic>P</italic><0.05）， and the TCM syndrome scores in observation group were lower than those in control group （<italic>P</italic><0.05）， the antipyretic time and urinary bacteria turning negative time of observation group were significantly lower than those in control group （<italic>P</italic><0.05）， the <italic>Escherichia coli， Enterococcus faecalis， Proteus mirabilis， Klebsiella pneumoniae</italic> pathogenic bacteria detected in both groups were both significantly lower than those before treatment （<italic>P</italic><0.05）. After treatment， the levels of inflammatory factors such as TNF-<italic>α</italic>， IL-6， IL-8， PCT， WBC and CRP in two groups were significantly lower than those before treatment （<italic>P</italic><0.05）， the immune function of the two groups was significantly improved， and the levels of CD3⁺， CD4⁺， C3， and C4 in observation group were higher than those in control group（<italic>P</italic><0.05）， and the CD8⁺ level was lower than that in control group （<italic>P</italic><0.05）. The incidence of adverse reactions had no significant difference between two groups. Conclusion:Qingre Lishi prescription has good clinical effect in treating children with acute bacterial lower urinary tract infection with bladder damp-heat syndrome. It can improve TCM syndromes and clinical symptoms. Its mechanism is related to inhibiting pathogenic bacteria， reducing inflammation， and improving immune function， and it has good security.

Early outcomes of elective surgery for colon cancer with preoperative mechanical bowel preparation: a randomized clinical trial / 南方医科大学学报

<p><b>OBJECTIVE</b>To compared the early outcomes of patients undergoing elective surgeries for colon cancer with and without preoperative mechanical bowel preparation.</p><p><b>METHODS</b>Between July, 2014 and February, 2016, patients undergoing elective surgery for colon cancer with primary anastomosis were randomly assigned into control group with mechanical bowel preparation 12 h before surgery and treatment group without mechanical bowel preparation. Baseline data collection was completed within 12 h after the operation. The levels of hemoglobin, total protein, albumin, prealbumin and albumin<globulin ratio of the patients were recorded at 1 day before surgery and 1 day and 5 days after the surgery. The patients were followed up till 30 days after the surgeries and the complications were recorded.</p><p><b>RESULTS</b>Seventy-six patients were assigned in the treatment group and 72 in the control group. Significant differences were found in the incidence of wound infection and intra-abdominal infection (P<0.05) but not in that of anastomotic leakage or early postoperative bowel obstruction (P>0.05) between the two 2 groups. The first flatus time (P=0.03) and prealbumin level on the first postoperative day (P=0.03) differed significantly between the two groups, but the operation time was similar between them (P=0.06).</p><p><b>CONCLUSION</b>In patients undergoing elective surgeries for colon cancer, preoperative mechanical bowel preparation is associated with increased postoperative complications, delayed recovery of intestinal motility and poorer nutrition status early after the operation.</p>

Detection and clinical features of human rhinovirus in hospitalized children with acute respiratory tract infection in eastern areas of Guangdong province / 中华流行病学杂志

Objective To investigate the prevalence and clinical features of human rhinovirus (HRV) infection in hospitalized children with acute respiratory (ARI) in eastern areas of Guangdong province from 2008 to 2010.Methods From Oct.2008 through Sep.2010,nasopharyngeal aspirates were collected prospectively,from hospitalized children with acute lower respiratory tract infection at the Second Hospital,affiliated to the Shantou University Medical College.Multiplex PCR was applied to detect ten kinds of viruses including HRV,RSV in the hospitalized children with respiratory tract infection.Clinical data on HRV-positive cases or RSV-positive cases were collected and analyzed.Results Among all the 1335 specimens,124 were confirmed as HRV-positive cases (9.3％),with IVA-positive rate as the highest (25.1％),followed by RSV-positive rate (15.1％).HRV infection occurred sporadically around the year,with the highest HRV-positive rate seen in spring 2009 and autumn in 2010.Symptoms,signs,chest X-ray,leukocyte count and CRP count did not differ between patients with co-infection or single HRV infection.Clinical symptoms or signs were similar between those with single HRV infection or single RSV infection in children,but the single RSV infected children were more frequently seen with wheeze and cough.28.4％ of the single RSV infected children had bronchiolitis while 10.7％ of single HRV infected children were seen (x2=0.281,P=0.596).Conclusion HRV was a relatively common cause for acute respiratory infections in the eastern areas of Guangdong province.The highest HRV-positive rate was slightly different in different years.Infants and young children were generally susceptible to rhinovirus infection.Bronchiolitis,wheeze and cough associated with HRV infection happened less than those caused by RSV.
