Objective To compare postoperative pulmonary infection in patients undergoing surgical operation at different surgical opportunities.Methods Patients who underwent surgical operation in a hospital from January to December 2014 were surveyed retrospectively,patients' data were reviewed,patients with postoperative pulmonary infection were compared.Results A total of 20 343 surgical patients were investigated,227(1.12%) had postoperative pulmonary infection.Postoperative pulmonary infection rate in patients undergoing emergency operation was higher than that of selective operation (5.13 % vs 0.70 %,x2 =307.49,P<0.001).Postoperative pulmonary infection rates in patients undergoing emergency neurosurgical,general surgical,and cardiothoracic surgical operation were all higher than selective operation (all P < 0.001).Among patients with pulmonary infection following emergency operation,the proportion of those who aged <60 years,with preoperative irrational antimicrobial use,cardiovascular disease,hypertension,and tracheotomy were all higher than those who received selective operation (all P<0.05);the proportion of patients with cancer is lower than that of elective surgery patients(P<0.05).Conclusion Postoperative pulmonary infection rate in patients undergoing emergency operation is higher than selective operation,postoperative pulmonary infection rates in patients undergoing emergency neurosurgical,general surgical,and cardiothoracic surgical operation are high.Patients with cardiovascular disease and hypertension are the focus of protection;for elective surgery,cancer patients are the focus of protection.

Objective To understand the occurrence of healthcare-associated infection(HAI) in intensive care units (ICUs) in secondary and above hospitals in a province, and provide basis for HAI management.Methods HAI management quality control center in a province performed targeted monitoring on HAI in ICUs in secondary and above hospitals in a province from July 1, 2010 to June 30, 2015.Results ICUs in 176 hospitals were monitored, the incidence of HAI in ICUs for 6 consecutive years was 7.23%, case incidence of HAI was 9.72%;incidence of HAI showed a decreased trend in 6 years(P<0.001).The adjusted rate of HAI per 1 000 patient days in the general hospital ICUs was higher than that of special hospital ICUs (4.30‰ vs 3.53‰).Incidence of HAI in surgical ICUs and general ICUs were both relatively higher, adjusted rates of HAI per 1 000 patient days were 4.79‰ and 4.21‰ respectively.Respiratory tract, urinary tract, and bloodstream infection were major HAI in ICUs, accounting for 68.64%, 14.45%, and 10.09% respectively, the utilization rates of central venous catheter, ventilator, and urinary catheter were 49.86%, 39.16%, and 81.95% respectively, incidence of three catheter-associated infection were 1.74‰, 13.77‰, and 2.08‰ respectively, incidence of three catheter-associated infection decreased year by year (P<0.001).The utilization rates of ventilator, central venous catheter, and urinary catheter in different ICUs were not correlated with the incidence of infection(all P>0.05).A total of 36 223 strains of pathogens were isolated, the top 6 isolated pathogens were Acinetobacter baumannii(22.77%), Klebsiella pneumoniae (11.96%), Pseudomonas aeruginosa(11.94%), Staphylococcus aureus (8.08%), Candida albicans (5.63%), and Escherichia coli(5.55%).The isolation rates of carbapenem-resistant Klebsiella pneumoniae showed a increased tendency for 6 years(P<0.05).Conclusion Continuous targeted monitoring on HAI in ICUs, regular analysis on risk factors for HAI, and timely implementation of intervention measures can effectively decrease the incidence of HAI.

The clinical internship is an important transitional period for humanistic spirit cultivation of the medical students.But in this period there are some problems exposed.For example,there is the lack of transitional link in management; the clinical instruction doctors lack educational consciousness or guidance ability,the medical students pay little attention to enhancing the individual humanistic spirit level and there is a gap between theory and practice of humanistic spirit for them.Strengthening training for students,attaching importance to training,selection and incentive of clinical instruction doctors and revising handbook of clinical internship will help to solve the problems.

Objective To explore the clinical manifestations,antimicrobial therapy,and risk factors of mortality in patients with Acinetobacter baumannii bloodstream infection.Methods Clinical data of 153 patients with Acinetobacter baumannii bloodstream infection hospitalized in First Affiliated Hospital of Zhejiang University from January 2013 to September 2014 were analyzed retrospectively.According to the 28-day survival after diagnosis,the patients were divided into death group (n =76) and survival group (n =77).Data related to demographic and clinical characteristics,underlying diseases,treatment,invasive procedures,bacterial resistance to antibiotics,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ)scores at onset,and antimicrobial therapy were collected.The index as an independent risk factor of mortality was demonstrated by multivariate logistic regression analysis.Results This study included 153 patients with Acinetobacter baumannii bloodstream infection.The 28-day mortality was 49.7%.The independent risk factors of mortality were APACHE Ⅱ score ≥22 at onset (OR =15.7,95% CI 5.1-48.1,P < 0.001),septic shock (OR =6.3,95 % CI 1.9-21.3,P =0.003),and administration of steroids (OR =3.6,95% CI 1.0-12.3,P =0.043).Compared with subjects treated with non-cefoperazone-sulbactam-based regimen,those treated with cefoperazone-sulbactam for multidrug-resistant Acinetobacter baumannii (MDR-AB) had significantly lower mortality on day7,day14 and day28 (8.9% vs 59.2%,31.1% vs 65.8%,44.4% vs 72.4% respectively).Conclusions The patients with Acinetobacter baumannii bloodstream infection have high mortality within one month.Administration of steroids and septic shock are associated with poor prognosis.APACHE Ⅱ score ≥ 22 at onset predicts adverse outcome.Cefoperazone-sulbactam-based antimicrobial therapy improves patients' survival.

Objective To retrospectively assess the clinical manifestations and treatment of secondary syphilis with ocular impairment as the initial symptom. Methods Clinical data were retrospectively analyzed on secondary syphilis with ocular impairment as the initial symptom collected from September 1998 to October 2008. Results There were 11 syphilitic patients presenting acute ocular impairment as their initial manifestation. Skin eruptions developed simultaneously with ocular impairment in 2 patients, following ocular impairment in 9 patients. All patients were positive for rapid plasma reagent test (RPR) and treponema pallidum haemagglutination assay (TPHA), but negative for HIV. Of these patients, 9 suffered from uveitis (iridocyclitis, choroiditis or panuveitis), 2 from optic neuritis; 3 had unilateral ocular involvement, 8 had bilateral ocular involvement. After treatment with injected penicillin or ceftriaxone sodium, 9 patients experienced complete visual recovery, 2 partial visual recovery. Conclusions Ocular impairment occurs in patients with secondary syphilis at a low incidence, with no characteristic clinical manifestations. For patients who have no response to conventional ocular therapy, ocular syphilis should be considered and serological examination for syphilis is recommended.

Objective To analyze the phenotypes of lymphocytes in cerebrospinal fluid derived from the patients with neurosyphilis. Methods Samples of cerebrospinal fluid from 12 patients with neurosyphilis and 20 patients with latent syphilis were collected and analyzed by flow cytometry for CD4 and CD25 expression. Results There was a significant increase in the number of white blood cells in the cerebrospinal fluid of patients with neurosyphilis. FACS analysis showed that most leukocytes were lymphocytes predominated with CD4 + T cells in neurosyphilis patients which were almost 4 times more than that in latent syphilis. However, there was a significant decrease in the proportion of CD4+ CD25high regulatory T cells (Tr) in neurosyphilis patients compared with that in latent syphilis patients. Conclusion A dramatic increase in CD4+ T cell frequency suggested its pathogenic role in neurosyphilis, whereas a decrease in CD25high Tr frequency indicated that CD4 + CD25high Tr cells might play an important role in immune homeostasis of central nervous system.
