Tianjin Medical Journal 2015;(8):886-888
Objective To explore the subjective global assessment (SGA) to evaluate the nutritional status of patients with chronic obstructive pulmonary disease(COPD). Methods Patients with stable COPD (n=122) were included and divid?ed into three groups base on their SGA scores:SGA-A (n=21), SGA-B (n=57), SGA-C (n=44). Nutritional status of all pa?tients was assessed by SGA. Anthropometric measurement, biochemical test, pulmonary function test, COPD assessment test (CAT) and shuttle walking test (SWT) were studied between all three groups to search statistical significance and correlation with SGA. Results Body mass index(BMI), arm muscle circumference (AMC) and forced expiratory volume in the first sec?ond%of predicted (FEV1%Pred) were all lower in SGA-B and SGA-C than those in SGA-A(P<0.05),there were no statis?tical differences of these parameters between SGA-B and SGA-C. Triceps skin fold (TSF) was lower in SGA-C than that in SGA-B than that in SGA-A, while CAT score is the reverse order (P<0.05). The walking distance of incremental shuttle walking test (ISWI) and the endurance time of endurance shuttle walking test (ESWI) were lower in SGA-C than that in SGA-A (P<0.05). There were no statistical differences of forced expiratory volume in the first second (FEV1)/forced vital ca?pacity(FVC), biochemical parameters between all three groups. SGA scores correlated positively with CAT and negatively with anthropometric parameters, FEV1%Pred and SWT (P<0.05). However no correlations was deduced between SGA scores with FEV1/FVC and biochemical parameters. Conclusion SGA scores correlated with anthropometric parameters, FEV1%Pred, CAT and SWT. SGA is an effective method to assess the nutritional status in patients with stable COPD.

Objective To observe the effects of salmeterol/fluticasone on the bone metabolism and bone density of the patients with moderate COPD and whether the effects is relate with inhaled corticosteroid course. Methods Sixty pa-tients with COPD were divided into 2 groups by random digit table. Patients in experimental group (n=30) were given conven-tional therapy with salmeterol/fluticasone one inhale(bid) for continuously 12 months while patients in control group (N=30) were given conventional therapy without any glucocorticoid.The bone mineral density (BMD) of the femoral triangle in all patients were measured by DXA before therapy, 3 months and 12 months after therapy. At the same time, biochemical indi-cators that are correlated with bone metabolism include bone gla protein (BGP) and alkaline phosphatase (ALP) were mea-sured by radioimmunoassay. Results The BMD, BGP and ALP of patients in experimental group and in control group be-fore therapy, 3 month and 12 month after therapy were compared. There is no significant difference (P>0.05) between these two groups before therapy and after 3 month but significant difference was shown after 9 months (P<0.05). Conclusion Short period inhaling salmeterol/fluticasone in patients with COPD is safe. But long-term inhaling salmeterol/fluticason may lead to decline of the bone density in patients with COPD.

BACKGROUND:Bone marrow mesenchyme stem cells are important non-hematopoietic stem cells in the bone marrow, which can stimulate angiogenesis. While, Slit can also stimulate angiogenesis, as many studies have proved. OBJECTIVE:To review the biological functions, clinical application and effects of bone marrow mesenchymal stem cells and Slit2 on promoting angiogenesis. METHODS:A computer-based online research of CNKI and PubMed databases was performed to col ect articles published between 1980 and 2014 with the keywords“MSCs”and“Slit2”in Chinese and English. There were 436 articles after the initial survey. Final y, 65 articles were included according inclusion and exclusion criteria. RESULTS AND CONCLUSION:Both bone marrow mesenchymal stem cells and Slit2 play an important role in promoting angiogenesis, but the relevance of bone marrow mesenchymal stem cells and Slit2 is stil controversial. If assuming that bone marrow mesenchymal stem cells secrete Slit2, more researches should be done to reveal whether bone marrow mesenchymal stem cells promoting angiogenesis is relevant to Slit2 and through which signaling pathway Slit2/Robo functions to adjust bone marrow mesenchymal stem cells thus to promote angiogenesis. If relevant, the transplantation of the Slit2 and bone marrow mesenchymal stem cells wil be a promising treatment of cerebral infarction and other central nervous injuries.

Objective To comprehensively evaluate the curative effect and adverse effects of rituximab plus cyclophosphamide, vincristine, doxoruhicin and prednisone(R-CHOP) chemotherapy and CHOP chemotherapy alone on the treatment for low and moderate malignant B cell non-Hodgkin lymphoma (NHL). Methods By the application of the systematic review method of Cochrance International Collaboration, the world-wide randomized controlled trials (RCT) on the comparison between different curative effects of R-CHOP and CHOP chemotherapy alone on the treatment low and moderate malignant B cell NHL was collected and the study results was evaluated systematically. Results Seven RCT studies involving 1569 patients and had no heterogeneity between themselves (χ=5.31,P=0.50). The baseline of patients characteristics was comparable in all the studies. By comparing complete response (CR) rate and adverse effects through fixed effect analysis model, the results showed that R-CHOP was better than CHOP chemotherapy on the treatment for low and moderate malignant B cell NHL(OR =2.22, 95 %CI 1.72-2.85, P <0.000 01), and adverse events of R-CHOP had no significant difference compared with CHOP chemotherapy alone (P>0.05). Conclusion With good curative effect on the treatment low and moderate malignant B cell NHL and without obvious differences from the CHOP chemotherapy alone in adverse effects, R-CHOP chemotherapy should be recommended as the best treatment method for low and moderate malignant B cell NHL And much more well-designed clinical RCT should be made to further prove its clinical effect.

Objective:To observe the effects of acupuncture and moxibustion at Feishu(BL13)on inflammatory responses and intestinal short-chain fatty acids(SCFAs)in rats with asthma. Methods:Fifty-six Sprague-Dawley rats were randomly divided into a normal group(16 rats)and a modeling group(40 rats).Rats in the modeling group were subjected to establishing asthma models using ovalbumin(OVA).Model evaluation was conducted using 4 rats from each group.The remaining rats that successfully developed asthma were then randomly divided into a model group,an acupuncture group,and a moxibustion group,with 12 rats in each group.Rats in the acupuncture group received acupuncture treatments,and those in the moxibustion group received moxibustion treatments,both at Feishu(BL13)for 30 min.Following the treatments,the rats were exposed to atomization excitation with a 1%OVA solution for 20 min daily for 14 consecutive days.At the end of the experiment,inflammatory markers in the rats'peripheral blood were analyzed using a biochemical method.In addition,inflammatory cells in the bronchoalveolar lavage fluid(BALF)were counted using Wright-Giemsa staining.The lung tissue of rats was examined under a light microscope after staining with hematoxylin-eosin to observe morphological or pathological changes.Furthermore,real-time fluorescence quantitative polymerase chain reaction was utilized to measure the mRNA expression of inflammatory factors in the lung tissue.Lastly,the concentration of SCFAs in the rat's feces was determined using gas chromatography-hydrogen flame ionization. Results:The levels of eosinophils(Eos),neutrophils(Neu),and lymphocytes(Lym)in the peripheral blood,as well as Eos and Neu in the BALF,and the expression of interleukin(IL)-4,IL-5,IL-13,IL-33,and thymic stromal lymphopoietin(TSLP)mRNAs in the lung tissue were all found to be significantly increased(P<0.05 or P<0.01);the lung tissue structure displayed severe injuries;the levels of acetic acid,propionic acid,isobutyric acid,butyric acid,and valeric acid in the feces decreased significantly in the model group(P<0.05 or P<0.01).Compared with the model group,the peripheral blood levels of Eos,Neu,and Lym,as well as Eos in the BALF,and the mRNA expression levels of IL-4 and IL-5 in the lung tissue decreased significantly in both the acupuncture group and the moxibustion group(P<0.05 or P<0.01).This reduction was accompanied by alleviated pathological damage in the lung tissue.Additionally,there were significant increases in the levels of acetic acid,propionic acid,isobutyric acid,and butyric acid in the feces in both the acupuncture group and the moxibustion group(P<0.05 or P<0.01).In the acupuncture group,the expression levels of Lym in the BALF and IL-13 mRNA in the lung tissue decreased significantly(P<0.05 or P<0.01).In the moxibustion group,the mRNA expression levels of IL-33 and TSLP in the lung tissue also reduced significantly(P<0.05 or P<0.01).Furthermore,the level of valeric acid in the feces increased notably in the moxibustion group(P<0.01).Compared with the acupuncture group,it was found that the mRNA levels of IL-5 and IL-13 in the lung tissue,as well as the acetic acid level in the feces,were significantly higher in the moxibustion group(P<0.05 or P<0.01). Conclusion:Both acupuncture and moxibustion were effective in reducing abnormal inflammation and regulating intestinal SCFAs in asthma model rats.Acupuncture demonstrated superiority in inhibiting pro-inflammatory factors,particularly IL-5 and IL-13,while moxibustion exhibited better regulation on intestinal metabolites SCFAs,especially acetic acid.

Objective:To evaluate the diagnostic value of refined transthoracic lung ultrasound(TLUS) scoring method in interstitial lung diseases(ILD).Methods:The TLUS was performed in 39 ILD patients in respiratory department and immunology department of the Second Affiliated Hospital of Fujian Medical University from March 2019 to February 2020. The ultrasonic recordings were evaluated by Buda ultrasound scoring method and refined ultrasound scoring method. The diagnostic efficacies of the refined ultrasound scoring method, Buda ultrasound scoring method and high resolution computed tomography(HRCT) scoring method for ILD were analyzed. The correlations between refined ultrasound score and Buda ultrasound score/HRCT score were evaluated. The difference of diagnostic efficacy between refined ultrasound scoring method and Buda ultrasound scoring method were analyzed in different severity of ILD. Then, the HRCT Warrick scoring method was used as the criterion to judge the severity of ILD, and the receiver operator characteristic (ROC) curve was plotted to predict the cutoff values of the fefined ultrasound score for different degrees of ILD.Results:①The sensitivity of the refined ultrasound scoring method in diagnosing ILD was 92.3%, specificity was 92.3%, area under ROC curve(AUC)=0.978, 95% CI=0.941-1.000. The sensitivity of Buda ultrasound scoring method in diagnosing ILD was 87.2%, specificity was 87.2%, AUC=0.950, 95% CI=0.892-1.000. The sensitivity of HRCT scoring method in diagnosing ILD was 97.4%, specificity was 97.4%, AUC=0.999, 95% CI=0.994-1.000. ②The correlations between the refined ultrasound score, the HRCT Warrick score and the Buda ultrasound score were high ( r=0.929, 0.920, 0.862 respectively, P<0.001). ③The values of refined ultrasound scoring method and Buda ultrasound scoring method consistently and significantly increased with the increasing severity of ILD. With regards to the former one, there were significant differences among mild group, moderate group and severe group ( P<0.05). ④The ROC curve confirmed that refined ultrasound score cut-off points for predicting mild and severe interstitial lung diseases, were 34 [sensitivity of 100%, specificity of 87.5% respectively, AUC=0.891, 95% CI=0.686-1.000] and 64.5 [sensitivity of 91.3%, specificity of 87.5% respectively, AUC=0.954, 95% CI=0.877-1.000]. Conclusions:The severity of the interstitial lung diseases could be evaluated by the refined ultrasound scoring method, which is useful in the semi-quantitative evaluation of ILD.
