OBJECTIVETo evaluate the efficacy and safety of PMC therapy (Prednisone, Methotrexate, Chloroquine) combined Langchuang Fuzheng Jiedu Capsule (LFJC), thus choosing a better therapy of integrative medicine for SLE in the period of glucocorticoid use.

METHODSSixty active SLE patients were randomly assigned to two groups, the control group and the treatment group. Those in the control group received PMC therapy (As for Prednisone, it was given at the daily dose of 1 mg/kg till 2 weeks after the condition being stable or after 8 weeks of treatment. Then the dose was reduced by 10% every two weeks. When the dose was reduced to 0.5 mg/kg daily, it was reduced by 2.5 mg per two weeks. When the dose was reduced to 15 mg daily, the dose was reduced to 2.5 mg per four weeks. As for Methotrexate, 10 mg each time, once a week. As for Chloroquine, 100 mg each time, twice daily), while those in the treatment group received PMC therapy (the same way as that for the control group) combined with LFJC (consisting of Astragalus membranaceus 50 g, Angelica sinensis 20 g, Ligusticum Chuanxiong 20 g, prepared Rehmannia Rhizome 30 g, Herba Serissae 30 g, Centella 30 g, centipede 4 g, scorpions 10 g, nidus versace 12 g, et al., 0.5 g per pill, containing 5.7 g crude drug. When the hormone was given at a large dose, LFJC was administered at 12 pills each time, three times daily). When the hormone was given at a middle dose, LFJC was administered at 8 pills each time, three times daily. When the hormone was given at a small dose, LFJC was administered at 6 pills each time, three times daily. The treatment course was six months. The improvement of symptoms and signs between before and after treatment, SLE disease activity index (SLEDAI), efficacy of Chinese medical syndrome, UPro quantitation, erythrocyte sedimentation rate (ESR), complement 3 (C3), C-reactive protein (CRP), the reduction and withdrawal of hormones, and infection of the respiratory tract were observed.

RESULTSThe difference in post-SLEDAI was obviously larger in the treatment group than in the control group (P < 0.05). The fatigue severity scale (FSS) was less after treatment than before treatment in the treatment group, showing statistical difference when compared with that of the control group (P < 0.05). The total effective rate was 93.33% in the treatment group, showing statistical difference when compared with that of the control group (86.66%; chi2 = 6.736, P < 0.05). The ESR decreased after treatment in the treatment group, showing statistical difference when compared with that of the control group (P < 0.01). C3 increased after treatment in the treatment group, showing statistical difference when compared with that of the control group (P < 0.05). The hormone was reduced to (13.70 +/- 5.42) mg/d by the end of the therapeutic course in the treatment group, obviously less than that of the control group [(17.63 +/- 7.80) mg/d, P < 0.05). Seven patients suffered from secondary infection of the respiratory tract infection in the treatment group (5 from upper respiratory tract infection and 2 from lower respiratory tract infection), obviously less than those of the control group (25 from upper respiratory tract infection and 10 from lower respiratory tract infection) (P < 0.05).

CONCLUSIONSPMC combined LFJC was a better treatment program for severe active SLE (SLEDAI > or = 15). It was more safe and effective when compared with using Western medicine alone. It could enhance the efficacy of hormones and help reduction/withdrawal of hormones.

Objective To analyze the distribution and antimicrobial resistance profile of clinical bacterial strains isolated from blood culture in China.Methods Clinical bacterial strains isolated from blood culture from participating hospitals of Blood Bacterial Resistance Investigation Collaborative System (BRICS) during January 2014 to December 2015 were collected.Antibiotic susceptibility tests were conducted with agar dilution or broth dilution methods as recommended by US Clinical and Laboratory Standards Institute(CLSI)2018.The data were analyzed with Whonet 5.6 software.Results During the study period,4 801 clinical bacterial isolates were collected from 26 hospitals,of which 1 798 (37.5％) were Gram-positive bacteria and 3 003 (62.5％) were gram-negative bacteria.The top 10 isolates were Escherichia coli (33.8％),coagulase-negative Staphylococcus (19.0％),Klebsiella pneumoniae (11.9％),Staphylococcus aureus (10.1％),Acinetobacter baumannii (4.0％),Pseudomonas aeruginosa (3.8％),Streptococcus (3.0％),Enterobacter sulcus (2.9％),Enterococcus faecium (2.8％) and Enterococcus faecalis (1.8％).Methicillin-resistant Staphylococcus aureus (MRSA) and methicillinresistant coagulase-negative Staphylococcus (MRCNS) accounted for 33.9％ (165/487) and 56.9％ (520/913) of Staphylococcus aureus and coagulase-negative Staphylococcus respectively.No vancomycinresistant Staphylococcus was detected.The resistance rate of Enterococcus faecium to vancomycin was 0.7％ (1/135),and no vancomycin-resistant Enterococcus faecaliss was detected.The positive rates of extendedspectrum β-1actamases(ESBLs)-producing Escherichia coli,Klebsiella pneumoniae and Proteus were 56.9％ (923/1 621),30.1％ (172/572) and 29.2％ (7/24),respectively.The positive rates of carbapenemresistant Escherichia coli,Klebsiella pneumoniae,Enterobacter,Salmonella and Citrobacter were 1.2％ (20/1 621),7.2％ (41/572),4.3％ (6/141),1.5％ (1/67) and 2.9％ (1/34),respectively.The resistance rates of Acinetobacter baumannii to polymyxin and tegacycline were 2.6％ (5/190) and 8.9％ (17/190)respectively,and that of Pseudomonas aeruginosa to polymyxin and fosfomycin were 1.1％ (2/183)and 0.6％ (1/183),respectively.Conclusions The surveillance results from 2014 to 2015 show that the main pathogens of blood stream infection in China are Gram-negative bacteria,while Escherichia coli is the most common pathogen,the detection rate of MRSA is lower than other surveillance data in the same period in China;carbapenem-resistant Klebsiella pneumoniae and Escherichia coli are at a low level as shown in this surveillance.

BACKGROUNDCombined emphysema and pulmonary fibrosis, including idiopathic pulmonary fibrosis (IPF), is a distinct disorder described with upper-lobe emphysema and lower-lobe fibrosis on chest computed tomography. Smoking appears to be the predominant risk factor for this disorder. We aimed to compare clinical features, smoking history, physiological and radiological findings between IPF with and without emphysema.

METHODSA sample of 125 IPF patients over a period of 48 months were evaluated. High resolution CT scans were reviewed blinded to clinical data. The IPF patients with or without emphysema were classified accordingly.

RESULTSThe prevalence of emphysema in this IPF sample was 70/125. IPF with emphysema was significantly associated with smoking status (OR 63; 95% CI 4.4 to 915; P = 0.002) and smoking pack year (OR 1.1; 95% CI 1.05 to 1.13; P = 0.000). The patients with IPF and emphysema had a higher decrease in carbon monoxide diffusing capacity adjusted for alveolar volume ((58±19)% pred vs. (66±21)% pred; P = 0.021) and a higher prevalence of pulmonary hypertension (24/70 vs. 7/55; P = 0.006). The two groups of patients had similar forced and residual volumes. No significant differences were found in cell differentials of bronchoalveolar lavage or the scores of fibrosis on chest CT. Survival of the patients with emphysema was significantly less than that of patients with IPF alone.

CONCLUSIONSCigarette smoking induces IPF combined with emphysema. Emphysema further impairs physiological function and increases the prevalence of pulmonary hypertension that leads to poor prognosis. The inclusion of the patients with combined pulmonary fibrosis and emphysema in IPF clinical trials may lead to under evaluation of the effect of treatment in patients.
