Objective To explore the clinical significance of C-reaction protein ( CRP ) and D-Dimer levels in patients with acute exacerbation of chronic obstructive pulmonary disease ( AECOPD ) complicated by pulmonary hypertension (PH) and their association with HP. Methods Arterial blood gas and levels of CRP and D-Dimer were detected in 150 patients with AECOPD. Results Levels of CRP, D-Dimer, and PaCO2 were higher but PO2 level was lower in patients with moderate to severe PH than those with mild PH and the control subjects. Levels of CRP and D-Dimer were higher in patients with mild PH than the control subjects. Levels of CRP, D-Dimer, and PCO2 levels had a linear relationship with PASP, while PO2 was negatively correlated with PASP. Levels of CRP and D-Dimer were positively related with PCO2, while were negatively correlated with PO2. Conclusions Levels of CRP and D-Dimer can be used as an indicator for estimating the severity of pulmonary hypertension in patients with AECOPD.

"Omics" and bioinformatics have brought new ideas to the study of traditional Chinese medicine. This study used metabonomics and network pharmacology to investigate the pharmacodynamic basis and regulation of Qishen Yiqi dropping pill (QDP) improving cardiac energy metabolism in rats with heart failure (HF). ¹H NMR metabonomics analysis showed that eight metabolites, including carnitine, glutamine, creatine, proline, homocitrulline, lactic acid, taurine and alanine appeared significant callback after QDP treatment for HF. The results indicate that QDP regulates the metabolism of carbohydrate, lipid, ATP and protein. The animal experiment was conducted in accordance with the regulations of the Ethics Committee for Experimental Animal Management and Animal Welfare of Institute of Materia Medica, Chinese Academy of Medical Sciences. A "drug-component-target-disease" network was established using network pharmacology, and the "component-target" sub-network related to the above energy metabolism processes was extracted by combining metabonomics results. Results revealed 79 chemical compounds and 47 potential targets of QDP involved in the regulation of energy metabolism, and identified key chemical components including ursolic acid, notoginsenoside G, ginsenoside-Rh1, and core targets such as INS, PPARG, and AKT1. The results also demonstrated the complex multi-target and multi-component relationship between QDP and HF from the perspective of energy metabolism. The molecular docking technique verified a strong interaction between some targets and chemical compounds, with affinities less than -5 kcal·mol^-1. The results of this study provide useful information for the clinical application, development, and utilization of QDP.

Objective To study the effects of EP4 and EP2 antagonists on the differentiation of Treg/ Th17 cells and disease progression in mice of collagen-induced arthritis (CIA) model.Methods DBA/1 mice wereimmunized subcutaneously twice at the root of the tail with type Ⅱ collagen emulsified in Freund's complete adjuvant.EP2 and EP4 antagonist therapies were intraperitoneally administrated for 14 consecutive days after the second immunization.Clinical signs,histological manifestation,serum interleukin (IL)-17 and quantity of CD4+CD25+Foxp3+ Treg cells were determined.ANOVA and t-test were used for statistical analysis.Results Clinical signs of the disease appeared on day 27 and peaked on day 35 after the first immunization.The quantity of CD4+CD25+Foxp3+ Treg cells in spleens [(1.67±0.15)％] and draining inguinal lymph nodes [(3.30±0.36)％] isolated from CIA mice were significantly lower than those of normal DBA/1 mice [(2.77±0.45)％ and (4.73 ±0.45)％ respectively,P＜0.05].Serum IL-17 level of CIA mice [(27±7) pg/ml] was significantly higher than that of normal DBA/1 mice [(14±4) pg/ml,P＜0.05].Intra-peritoneal injection of EP4 but not EP2 antagonist to CIA mice decreased paw edema and swelling,and alleviated the histological manifestations (1.8±1.0 vs 3.5±0.6,P＜0.05) on day 35 after the first immunization.The percentages of CD4+CD25+Foxp3+ Treg cells in both inguinal lymph nodes [(4.20±0.32)％] and spleens [(2.63±0.40)％] were significantly higher in EP4 antagonist-treated but not EP2 antagonist-treated CIA mice compared with CIA mice group [(3.30±0.36)％ and (1.67±0.15)％ respectively,P＜0.05].The level of serum IL-17 was significantly lower in EP4 antagonist-treated [(15±7) pg/ml] but not EP2 antagonist-treated CIA mice compared with CIA mice group [(27±7) pg/ml,P＜0.05].Conclusion EP4 antagonist therapy alleviates clinical symptoms of CIA,improves the histological manifestations,decreases the serum IL-17 level and increases the percentages of CD4+CD25+Foxp3+ Treg cells in both spleens and draining inguinal lymph nodes,so targeting EP4 receptor may be a new possible therapeutic possibility in the prevention and treatment of rheumatoid arthritis.

Objective To investigate the expression of human epididymal protein 4 (HE4) in chronic kidney disease (CKD) and its clinical value.Methods From April 2014 to December 2015,Serum samples of 92 non-cancer patients diagnosed as CKD and 84 healthy controls were collected in Nantong University Hospital.HE4,BUN,Scr,Cys C and β2MG were detected.The difference of HE4 expression in different stages of CKD and the correlation of HE4 with Urea,Scr,Cys C and β2MG were analysized,respectively.ROC curve was used to evaluate the auxiliary diagnostic value of HE4,BUN,Scr,Cys C and β2MG.Results The serum HE4 expression in patients with impaired renal function was 388.2 (130.1～1 659.5)mIu/ L,(F=16.237,P=0.001).Which was significantly higher than that in the control group [38.1 (32.77 ～ 48.17)mIu/L].The serum HE4 expression was increased by the stage of renal damage and the difference was existed among different groups (P＜0.05).HE4 expression was positive related with Cys C and β2MG.The AUC of HE4,BUN,Scr,Cys C and β2MG were 0.878,0.785,0.816,0.874 and 0.819,respectively.Conlusion It needs to consider the exsits of impaired renal function when the HE4 was detected.The HE4 might be a novel early diagnostic indication for CKD.

To observe different expression patterns of β-catenin and its clinical significance in colorectal cancer (CRC).Methods A total of 181 cases of CRC tissues and 30 cases of normal colorectal tissue were investigated by immunohistochemistry for the expression of β-catenin.Results The expression rate of β-catenin was 56.9％ (103/181) in CRC,and higher than that in normal colorectal tissue (P ＜ 0.05).The overexpression of nuclear β-catenin was significantly correlated with histological differentiation,lymph node metastasis and Dukes' stage in CRC (P ＜ 0.05),and no relationship with other pathological parameters,such as age,gender and the depth of infiltration.The incomplete membranous expression of β-catenin was significantly correlated with histological differentiation,the depth of infiltration,lymph node metastasis and Dukes' stage in CRC (P ＜ 0.05).The high expression of nuclear β-catenin related to histological differentiation and Dukes' stage in CRC (P ＜ 0.05).In the follow-up data of 82 cases of CRC,the expression of nuclear β-catenin was associated with poor prognosis,and the 5-year survival rate was significantly lower than that of self-control groups (P ＜ 0.05).Conclusion β-catenin plays important roles in colorectal carcinogenesis.Abnormal expression of β-catenin was related to the aggressive progression of CRC and may be helpful for evaluating the prognosis of patients with CRC.β-catenin is expected to become a new target for diagnosis and treatment of CRC in future.

BACKGROUND: The clinical features and classification of various anomalous synkinetic movements related to ocular muscles caused by abnormal innervations have not been fully understood.OBJECTIVE: To report and analyze the clinical features of anomalous synkinetic movements related to ocular muscles caused by abnormal innervations, as well as to classify them according to the same neuromuscular nerves.DESIGN: A retrospective case analysis.SETTING: Department of Ophthalmology, the Affiliated Hospital of the Medical College of Qingdao University.PARTICIPANTS: The study was mainly conducted in the Department of Ophthalmology, the Affiliated Hospital of the Medical College of Qingdao University. A total of 836 cases of abnormal ocular movements were found from January 1997 to January 2002. Among them 67 cases of anomalous synkinetic movements were diagnosed.METHODS: All patients were inquired of case history and their ocular movements were examined. The anomalous synkinetic movements were found and classified into congenital and acquired. All cases were analyzed according to the same neuromuscular nerves, such as between branches of oculomotor nerve, oculomotor and abducens nerve, supranucleus and other anomalous synkinetic movements.lous synkinetic movements were determined by inquiring the history of observed.RESULTS: Sixty-seven anomalous synkinetic movements (8%) of 836 abnormal ocular movements were diagnosed; congenital anomalous synkinetic movements were the most common ones (88.06%) and were often seen in patients with Duane's syndrome. Anomalous synkinetic muscles occurred the most common between lateral and medial rectus, lateral rectus and levator palpebrae muscle (36.89% respectively) in congenital cases, and those occurred between inferior rectus and levator palpebrae muscle more commonly (30%) in acquired cases.CONCLUSION: Anomalous synkinetic movements related to ocular muscles are not infrequently seen. When we find paradoxical movements between ocular muscles, or between ocular muscles and other unrelated muscles, anomalous synkinetic movements should be considered.
