Objective To investigate the application value of pan-immune-inflammation value(PIV),hypersensitive C-reactive protein(hs-CRP)/albumin(ALB)ratio(HCAR)and procalcitonin/platelet count ratio(PCT/PLT)in pulmonary infection in elderly patients with chronic obstructive pulmonary disease(COPD).Methods A total of 143 elderly patients with COPD and pulmonary bacterial infection were selected as the infected group.Meanwhile,143 elderly patients with COPD and without pulmonary infection were selected as the uninfected group.Patients in the infected group were furthrer divided into the mild group(47 cases),the moderate group(51 cases)and the severe group(45 cases)according to the degree of pulmonary infection.They were divided into the favorable prognosis group(112 cases)and the poor prognosis group(31 cases)according to the prognosis.Blood biochemical indicators,PIV,HCAR and PCT/PLT were compared between groups.The relationship between above indicators and pulmonary infection,infection degree and the prognosis was analyzed.Results Compared with the uninfected group,neutrophil(NEU),monocyte(MON),hs-CRP and PCT levels were higher,while lymphocyte(LYM)and ALB levels were lower in the infected group(P＜0.05).PIV,HCAR and PCT/PLT were higher in the infected group and the poor prognosis group than those in the uninfected group and the favorable prognosis group,respectively(P＜0.05).PIV,HCAR and PCT/PLT in the mild group,the moderate group and the severe group increased in sequence(P＜0.05).Spearman correlation analysis showed that PIV,HCAR and PCT/PLT were positively correlated with the degree of pulmonary infection(P＜0.05).Multivariate Logistic regression analysis showed that high levels of PIV,HCAR and PCT/PLT were independent risk factors for pulmonary infection in elderly patients with COPD(P＜0.05),and also independent risk factors for poor prognosis in patients with pulmonary infection(P＜0.05).The areas under the curve(AUC)of PIV combined with HCAR and PCT/PLT for diagnosing pulmonary infection in elderly patients with COPD and predicting poor prognosis in patients with pulmonary infection were 0.980 and 0.910(P＜0.05).Conclusion PIV,HCAR and PCT/PLT are related to COPD with pulmonary infection in the elderly.They can help to identify pulmonary infection,judge the condition of pulmonary infection and evaluate the prognosis in patients with pulmonary infection.

Objective To analyze levels of pan-immune-inflammation value(PIV),interleukin-6(IL-6),heparin-binding protein(HBP)and prealbumin(PAB)in patients with severe community-acquired pneumonia(CAP),and their values in evaluating the therapeutic effect at 72 h after admission.Methods According to the initial(72 h)treatment outcome,120 patients with severe CAP(the severe group)were divided into the effective group(n=87)and the failed group(n=33).Meanwhile,120 patients with non-severe CAP admitted in the same period were selected as the non-severe group.PIV,IL-6,HBP and PAB levels on the day after admission were compared between the severe group,the non-severe group,the failed group and the effective group.The value of above indicators in evaluating the condition of CAP and the therapeutic effect at 72 h after admission separately and in combination were analyzed using receiver operating characteristic(ROC)curves.Results Compared with the non-severe group,there were higher PIV,IL-6 and HBP levels,and lower PAB levels in the servere grouop(P＜0.05).ROC curves indicated that for evaluating severe CAP using a single indicator,the area under the curve(AUC)of PIV was the highest[0.830(95%CI:0.780-0.881)].The AUC of PIV combined with IL-6,HBP and PAB for evaluating severe CAP was 0.929(95%CI:0.892-0.967),which was higher than that of evaluation using a single indicator(P＜0.05).Compared with the effective group,there were higher PIV,IL-6 and HBP levels,and lower PAB level in the failed group(P＜0.05).ROC curves indicated that for evaluating the therapeutic effect on severe CAP at 72 h after admission using a single indicator the AUC of PIV was the highest[0.777(95%CI:0.692-0.862)].The AUC of PIV combined with IL-6,HBP and PAB for evaluating the therapeutic effect on severe CAP at 72 h after admission was 0.916(95%CI:0.846-0.986),which was higher than that of evaluation using a single indicator(P＜0.05).Conclusion Detection of PIV combined with IL-6,HBP and PAB has a good value in evaluating the condition of patients with CAP and the therapeutic effect on severe CAP at 72 h after admission.

OBJECTIVES: To investigate the expression of cartilage acidic protein 1 (CRTAC1) in gastric cancer (GC) and its effect on biological behaviors and immune cell infiltration of GC. METHODS: Transcriptomic, GO and KEGG analyses were conducted to investigate the association of CRTAC1 expression with prognosis of GC patients and its involvement in cell function and signaling pathways. ESTIMATE algorithm was used to analyze the effect of CRTAC1 expression on the tumor microenvironment and the tumor mutation load. In two GC cell clines (HGC-27 and MKN-74), CCK8, EdU and clone formation assays, flow cytometry, and Hoechst staining were used to examine the effects of CRTAC1 knockdown on cell proliferation, cell cycle changes and apoptosis. Wound healing assay, Transwell assay, and Western blotting were performed to analyze the effect of CRTAC1 knockdown on GC cell migration and the underlying mechanism. RESULTS: Bioinformatics analysis showed significantly higher expression of CRTAC1 in GC tissues than in adjacent tissues (P<0.05). Age and tumor stage were both prognostic risk factors in GC patients with high CRTAC1 expression (P<0.001). Analysis using ESTIMATE algorithm showed that CRTAC1 expression increased immune cell infiltration and decreased tumor mutational load in GC (P<0.001). In HGC-27 and MKN-74 cells, CRTAC1 knockdown significantly inhibited cell proliferation and migration and promoted cell apoptosis. Western blotting demonstrated that CRTAC1 knockdown significantly increased E-cadherin expression and reduced the expression levels of vimentin, p-PI3K, AKT2, p-AKT and p-mTOR in GC cells. CONCLUSIONS High expression of CRTAC1 in GC tissues affects immunotherapeutic efficacy and prognosis of the patients, possibly by promoting epithelial-mesenchymal transition via modulating tumor mutational load, tumor microenvironment, and the PI3K/AKT signaling pathway.

Objective To explore the application effects of hip muscle training on female patients with stress urinary incontinence (SUI).Methods Totally 48 female patients with mild to moderate SUI were recruited in this study from the Second Hospital of Hebei Medical University from January to November 2015 by using purposive sampling method. According to the random number table,the participants were divided into the intervention group (n=24) and the control group (n=24). Patients in the intervention group received resisted hip muscle exercise,including the hip internal rotation and hip external rotation. Patients in the control group received conventional pelvic floor muscle exercise (PFME). The intervention lasted for 12 weeks,and the application effects were evaluated by the questionnaire of urinary incontinence quality of life (I-QOL) and the urine pad test before the intervention,eight weeks,and 12 weeks after the intervention.Results After the intervention,the urine leakage was significantly decreased,and the I-QOL score was increased (P<0.05). Although the urine leakage had no statistical difference between two groups (P>0.05),the total I-QOL scores and the scores of social barriers dimension were higher inr the intervention group compared with that in the control group (P<0.05). But on the dimension of limited behavior and the psychological impact,there were no statistical differences between two groups (P>0.05).Conclusions Resisted hip muscle training can effectively decrease the urine leakage and improve the quality of life of female patients with mild to moderate SUI.

Urinary incontinence is a common disease of women. Approximately there are two billion patients with urinary incontinence globally, SUI accounts for almost 1/2 of urinary incontinence. Stress urinary incontinence not only affects women′s health and limits the patients′ daily behavior and physical activity, resulting in anxiety, depression, etc. In view of the high prevalence of SUI, the high impact rate and low rate of diagnosis and treatment, the clinical medical professionals need to understand the relevant contents of SUI. This review will summarize the risk factors about stress urinary incontinence and the development of pelvic floor muscle rehabilitation. We hope to provide reference for clinical practice.
