Effectiveness and Safety of Umbilicus Treatment with Modified Dinggui Powder () in Patients with Chronic Nonbacterial Prostatitis: A Randomized, Double-blind, Placebo-controlled Clinical Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate the effectiveness and safety of Chinese herbal external umbilicus treatment with Modified Dinggui Powder (, MDGP) in patients with chronic nonbacterial prostatitis (CNP).@*METHODS@#A randomized, double-blind, placebo-controlled clinical trial was conducted among 72 patients with CNP. Participants were randomly allocated to a treatment group and a placebo group using computer software in a 1:1 ratio, and received either MDGP external umbilicus treatment (MDGP group, 36 cases) or placebo control groupl (36 cases) at acupoints Shenque (CV 8), twice a week for 4 weeks. In addtion, patients all received herbal medicine treatment twice a day for 4 weeks. The primary outcomes was the US National Institutes of Health Chronic Prostatitis Symptom Scores Index (NIH-CPSI) with a questionnaire at weeks 2 and 4. The secondary outcomes including prostatic fluid examination (white blood cells and lecithin bodies), the clinical efficacy evaluation, and the adverse events were also assessed during the entire trial.@*RESULTS@#The NIH-CPSI scores regarding pain or discomfort scores showed greater improvement in the MDGP group than placebo control group at weeks 2 (P0.001) and week 4 (P0.004), respectively. NIH-CPSI scores of symptom severity, total scores, the amount of leukocytes number in the prostatic fifluid in the MDGP group were significantly improved (P0.05). The clinical effective rate was 73.53% (25/34) in the MDGP group, which was significally higher than the placebo control group with 48.39% (25/31, P<0.05). Patients were blinded successfully, and no serious adverse effects were found during the trial.@*CONCLUSION@#A 4-week course of umbilicus treatment with modified Dinggui Powder seems to relieve pain and symptom severity effectively and increase the amount of leukocytes number in patients with CNP (Trial registration No. ChiCTR1800014687).

Logistic regression analysis on risk factors for surgical site infection after colorectal surgery / 中国感染控制杂志

Objective To explore risk factors for surgical site infection(SSI) in colorectal surgery,and provide evidence for formulating measures for preventing SSI.Methods Patients who underwent colorectal surgery in the department of gastrointestinal surgery of a hospital from June 2013 to June 2016 were surveyed retrospectively,the related risk factors for SSI were analyzed by unconditional logistic regression analysis.Results Among 397 patients who underwent colorectal surgery,67 (16.88％) had SSI.Logistic regression analysis showed that smoking,low albumin,seniority of surgeons less than 5 years,irrational use of antimicrobial agents during perioperative period,and high National Nosocomial Infection Surveillance (NNIS) score were independent risk factors for SSI after colorectal surgery (all P＜0.05).Conclusion There are multiple risk factors for SSI after colorectal surgery,it is necessary to pay attention to it and formulate preventive measures,so as to reduce the occurrence of SSI effectively.

Common bacteria and change in antimicrobial resistance in the intensive care unit of a hospital from 2009 to 2013 / 中国感染控制杂志

Objective To investigate the common bacteria and change in antimicrobial resistance in an intensive care unit (ICU)in the past 5 years,and provide evidence for rational use of antimicrobial agents.Methods Bacteria isolated from ICU patients in a tertiary first-class hospital from 2009 to 2013 were collected,identified,and per-formed antimicrobial susceptibility testing.Results A total of 1 196 bacteria isolates were isolated in 2009-2013, the top five species were Acinetobacter baumannii (A.baumannii,29.60%),Pseudomonas aeruginosa (P . aeruginosa,14.38%),Staphylococcus aureus (S .aureus ,12.21 %),Escherichia coli (E.coli,12.21 %),and Klebsiella pneumoniae (K .pneumoniae ,11 .37%).Resistance rates of S .aureus to oxacillin,gentamycin, clindamycim,ciprofloxacin,and rifampicin showed a decreasing tendency from 2009 to 2013(all P 80% in 2009-2011 and 10.53% in 2013,A.baumannii had high resistance rates to most antimicrobial agents(resistance rates were >80%)during 5 years.Resistance rates of K .pneumoniae and E. coli to piperacillin/tazobactam,cefazolin,cefepime,amikacin,and aztreonam had a decreased tendency in 2009 -2013(all P <0.05).Conclusion The common bacteria causing infection in the ICU of this hospital showed a down-ward trend,which may be related to the introduction of national policies and management of hospital,continuous management of antimicrobial agents is suggested,antimicrobial agents should be used rationally to prevent the in-crease of bacterial resistance.

Mechanism of erythrocyte phosphatidylserine exposure induced by high concentrated glucose / 中国实验血液学杂志

This study was aimed to investigate the mechanism of phosphatidylserine exposure of human erythrocytes induced by high concentrated glucose. After exposure to high concentrated glucose, the phosphatidylserine (PS) exposure and forward scatter value were analyzed by flow cytometry; the activities of caspase-3 and caspase-8 were detected; The inhibitory effect of leupeptin on cell PS exposure induced by high concentrated glucose was observed by flow cytometry and fluorescent microscopy. The results showed that the high concentrated glucose could induce PS exposure of erythrocytes and this inducing efficiency was dependent on the glucose concentrations. With increase of the glucose concentrations, the percentages of cells with exposed PS also increased. When the glucose concentration was 0.8 mol/L, the PS exposure was over 80%. However, caspase-3 and caspase-8 were not activated during PS exposure of cells induced by high concentrated glucose, but leupeptin could significantly inhibit PS exposure and volume shrinkage induced by high concentrated glucose. With increase of the leupeptin concentrations, the percentage of cells with exposed PS decreased and the cell volume increased. It is concluded that the high concentrated glucose can result in serious PS exposure, which does not depend on caspase. It can be hypothesized that the PS exposure of erythrocytes induced by high concentrated glucose may be controlled by an unknown pathway sensitive to leupeptin.

Experiment and Pondering of Applying Bilingual Teaching to the Course of Pathology / 中华医学教育探索杂志

An experiment of applying bilingual teaching to the course of pathology on the sophomores (students in Grade 2002) was carried out in our department in April 2004. This paper will research the feasibility and necessity of the methodology,ponder the problems in the course of teaching and put forward some suggestions in order to conduct bilingual teaching smoothly on the basis of practice and theory.

Complications of pericardiocentesis and drainage for pericardial effusion / 中国介入心脏病学杂志

Objective Pericardiocentesis and drainage are the common measures for the treatment of cardiac temponade and massive pericardial effusion. In this issue, the complications of pericardiocentesis and drainage were discussed. Methods 5 in-hospital cases of cardiac temponade or massive pericardial efiusion who had complications of pericardiocentesis and drainage were reported and analyzed. Results The complications were 2 cases with neural mediated syncope, 1 case with pleural efiusion, 1 case dead of acute right ventricular dilation, and 1 case with acute pulmonary edema and effusion leaking into the subcutaneous tissue. Conclusion The importance of hemodynamic change during pericardiocentesis and drainage could not be over-emphasized, and the patients whose hemodynamic status were unstable should be monitored by bedside hemodynamic monitoring or echocardiography. Also we should pay more attention to the drainage catheter per se, which may cause the complications.
