Objective:
To investigate the interaction between traditional Chinese medicine (TCM) syndromes of histiocytic necrotizing lymphadenitis (HNL) and pathological types of HNL, so as to discover the distribution rule of TCM syndromes for indiction of intervention of HNL.
Methods:
A total of 166 patients with HNL were included. The baseline data of the patients, clinical feature, the four diagnosis information of TCM and histopathological of cervical lymph node were collected. The syndromes of TCM were judged. The pathological types were confirmed by cervical lymph node biopsy. The Multi-way ANOVA was used to analyze the correlation between traditional Chinese medicine syndromes of HNL and its pathological types.
Results:
Among the 166 patients, the ratio of different types are as follow: wind-heat and phlegm-toxin syndrome (57.83%, 96/166), heat-toxin exuberance syndrome (34.34%, 57/166), and phlegm and blood stasis syndrome (7.83%, 13/166). The pathological types include proliferative type (57.83%, 96/166), necrotizing type (35.54%, 59/166), and xanthomatous type (6.63%, 11/166). There were significant differences in targeted lymph node diameter, pain scores, body temperature (

Objective To investigate the morbidity and risk factors of peripherally inserted central catheter (PICC) related bloodstream infection and the distribution and antimicrobial susceptibility of pathogens in patients with hematological malignancy for better prevention and management of such infections. Methods The relevant data were collected from the patients with hematologic malignancy and PICC in hematology department from July 2013 to November 2016. The risk factors of PICC related bloodstream infection were analyzed. Blood samples and catheter-related blood samples were taken for culture of pathogens. The pathogens were identified on VITEK-32. Antimicrobial susceptibility was tested by using Kirby-Bauer method. Results A total of 10 213 patients with PICC were included in this study. PICC related bloodstream infection was identified in 280 (2.74%) patients, about 0.55 per 1 000 PICC days. The main risk factors of PICC related bloodstream infection were type of hematological malignancy (P<0.001) and days of indwelling PICC (P<0.001). A total of 322 strains of pathogenic bacteria were isolated, including gam-negative bacteria (73.91%), gam positive bacteria (22.05%) and fungus (4.04%). The gram-negative species isolated from bloodstream were mainly Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Stenotrophomonas maltophilia. E. coli and K. pneumoniae isolates were relatively sensitive to piperacillin-tazobactam, cefepime, cefoperazone-sulbactam, imipenem, gentamicin and amikacin. S. maltophilia isolates were relatively sensitive to piperacillin-tazobactam, ceftazidime, cefoperazone sulbactam and ciprofloxacin, while P. aeruginosa strains were relatively sensitive to the commonly used anti-Pseudomonas antibiotics. The gram-positive isolates including Staphylococcus epidermidis, Staphylococcus hominis and Staphylococcus haemolyticus were all susceptible to vancomycin, linezolid, and teicoplanin. The most frequently identified fungal species was Candida tropicalis. Conclusions Prolonged duration of PICC may increase the risk of central line-associated bloodstream infection (CLABSI). The incidence of CLABSI is associated with the type of hematological malignancy. CLABSI pathogens are mainly gram-negative microorganisms with various levels of antibiotic resistance. Clinicians should adhere to standard operating procedures, strengthen surveillance of patients with PICC, evaluate the risk dynamically, and remove PICC as early as possible.

Objective To investigate the characteristics of ocular surface inflammation index after pterygium excision by using Oculus Keratograph(R) 5M and Visual analogue scale and evaluated the effectiveness of antiinflammatory treatment.Methods A prospective case control study was performed.Eighteen patients (6 males and 12 females) who suffered from primary pterygium were recruited in Zhongshan Ophthalmic Center from June to September 2016.All patients were treated with monocular pterygium excision combined with amniotic membrane transplantation.Anti-inflammatory treatment was given after surgery,and the ocular inflammation index was evaluated at preoperative and 1st,3rd,7th,10th,30th and 60th day postoperative.The temporal conjunctival hyperemia index (TCHI) was assessed by Oculus Keratograph(R) 5M with a red eye index analysis software.Ocular symptom scores (OSS) and visual analogue scale (VAS) were used to analyze the subjective symptoms of the patients.Fluorescein staining was used to detect the epithelization of corneal and scleral wound.The best corrected visual acuity (BCVA),intraocular pressure and complications were evaluated in this study.This study was approved by the Medical Ethics Committee of Zhongshan Ophthalmic Center of Sun Yat-sen University (2016KYPJ024).All patients signed informed consent for clinical research.Results No drug-related ocular and systemic adverse events were found during the follow-up.Corneal epithelial defect was recovered on 10th day,and conjunctival epithelization was observed in sclera exposed area on 30th day.The BCVA on the 60th day was 0.12±0.17,which was significantly lower than 0.34±0.36 preoperatively (t =3.401,P =0.003).Compared with those before surgery,OSS and VAS were significantly increased on 1 st day (OSS:Z =-4.255,P =0.000;VAS:Z =-5.256,P =0.000).The OSS on 7th day was not significantly different from that before surgery (Z=-0.958,P=0.372).VAS decreased to baseline on 30th day.The OSS on 60th day after surgery was significantly lower than that before surgery (Z =-2.397,P =0.037).TCHI was higher than 1.2 preoperatively,and increased to the highest on 1 st day after surgery,with significant difference between them (t=-6.620,P=0.000).The TCHI decreased to baseline on 7th day,no significant difference were obtained when compared with preoperative TCHI (t =-1.050,P =0.310),and TCHI on 60th day after surgery was lower than that before surgery,with significant difference between them (t =2.758,P =0.020).Conclusions The subjective symptoms combined with conjunctival hyperemia can be more accurate assessment of ocular surface inflammation in the perioperative period of pterygium surgery,which can be used as an evaluation index to assess the effectiveness of anti-inflammatory treatment.
