4.Detection of urinary monocyte chemoattr actant protein-1 and interferon-γ-inducible protein-10 to recognize the disease activity of lupus nephritis
Chinese Journal of Rheumatology 2014;18(11):747-751,后插2
Objective In this study,we measured the levels of urinary monocyte chemoattractant (MCP)-1 and interferon-γ-inducible protein (IP-10) and further analyzed their associations with clinical and pathological data in lupus nephritis patients in order to find the non-invasive biomarkers which canpredict disease activity.Methods MCP-1,IP-10,VEGF levels were measured in urine samples from 64 lupus nephritis patients and 20 healthy volunteers.Clinical disease activity was determined by SLEDAI and BILAG scores.The lupus nephritis patients were divided into two groups:active disease group (SLEDAI scores ≥ 10points,n=36) and non-active group (SLEDAI score<10 points,n=28).Of all patients enrolled,37 patients had a concomitant kidney biopsy performed at the time of urine collection.The predictive performance of uri-nary MCP-1 and IP-10 for renal flare,the Student's t test,Mann-Whitney U test,Chi-square test,and re-ceiver operating characteristic (ROC) curves were constructed for analysis.Results The urinary MCP-1 and urinary IP-10 levels of the active group was significantly higher than that of the non-active group [MCP-1672.39(318.05,2 554.23)pg/ml vs 152.52,(55.61,330.44)pg/ml,Z=-4.717,P<0.01; IP-10 (38±19) pg/ml vs (22±16) pg/ml,t=3.576 P<0.01].The level of urinary MCP-1 was positively correlated with the levels of hematuria and 24 hours protein quan-tification,as well as the scores of SLEDAI and BILAG (rbemahuria=0.570,P=0.000; r24hpro=0.569,P=0.000; rSLEDAI=0.600,P=0.000; rBILAG=0.606,P=0.000),and it was also positively correlated with the scores of cellular crescent,wire loop,and AI (rCC=0.405,P=0.015; rwire loop=0.430,P=0.014; rAI=0.352,P=0.003),while nega-tively correlated with the level of C3 and plasma albumin (rc3=-0.564,P=0.000; ralb=-0.587,P=0.000).It had no correlation with the scores of wire loop and CI (P> 0.05).The level of uIP-10 was positively correlated with the protein quantification in 24 hours and the scores of SLEDAI and BILAG (r24hpro=0.305,P=0.018; rSLEDAI=0.334,P=0.009; rSILAG=0.496,P=0.000),while negatively correlated with the level of C4 (rC4=-0.301,P=0.016).The R0C curve of uMCP-1 to predict the activity of SLE showed that its specificity was 75.0%,sensitivity was 83.3%,and the area under the ROC curve was 0.85±0.05.The ROC curve of urinary IP-10 to predict the activity of SLE showed that its specificity was 50.0%,sensitivity was 97.2%,its area under the ROC curve was 0.74±0.06.The ROC curve of urinary MCP-1 to predict renal flare shows that its specificity was 45.5%,its sensitivity was 100%,and the area under the ROC curve was 0.74±0.80.The ROC curve of urinary IP-10 to predict renal flare showed that its specificitywas 36.4%,its sensitivity was 73.3%,and its area under the ROC curve was 0.49 ±0.10.Conclusion Urinary MCP-1 and urinary IP-10 predict renal flare in patients with lupus nephritis.Furthermore,urinary MCP-1 is a more specific and sensitive forecaster of renal flare in patients with a history of lupus nephritis than urinary IP-10.
5.Clinical research in controlling infusion rate during nasal feeding by infusion pump
Chinese Journal of Practical Nursing 2010;26(14):40-41
Objective To investigate and improve the methods of nasal feeding to reduce the occurrence of complication such as diarrhea and vomiting.Methods We separated 140 patients with heavy craniocerebral injury into the control group (50 patients) and the experimental group (90 patients) according to different nasal feeding methods. For the control group traditional method was used. For the experimental group infusion pump was used to control infusion rate. The incidence of complication was compared between two groups. And within experimental group, the same nutrient solutions in respect of type and volume were infused during 10 hours, 16 hours, and 18 hours respectively. The relationship between infusion rate and the occurrence of complication was observed, analyzed and compared to seek for the most suitable enteral nutrition route which incurred the least complication.Results The incidence of diarrhea and vomiting in the experimental group was lower than that of the control group. And there were no significant differences in the occurrence of complication by using infusion pump at three different infusion rates within the experimental group. Conclusions The application of infusion pump in nasal feeding can reduce the incidence of complication and infusing nutrient solution at a slow rate was not necessary.

7.Proprotein convertase subtilisin/kexin type 9 and regulation of lipid metabolism
International Journal of Cerebrovascular Diseases 2009;17(3):211-215
Hypercholesterolemia and coronary heart disease caused by it have become the most important factors threatening human health. The lipid metabolism-related studies are increasingly receiving attention. Recent studies have demonstrated that proprotein convertase subtilisin/kexin type 9 (PCSK9), a family member of precursor protein-converting enzyme, plays an important role in the regulation of lipid metabolism. The expression and mutation of PCSK9 gene are closely correlated with the content of low-density lipoprotein receptor (LDLR). The excessive expression of PCSK9 promotes the degradation of LDLR, thereby increasing the levels of plasma LDL; whereas the inhibition of PCSK9 gene expression causes the decreased levels of plasma LDL. Therefore, it is promising to develop novel medications for treating hypercholesterolemia, controlling hyperlipermia and preventing coronary heart disease by studying the mechanism of PCSK9.

Cancer Research and Clinic 2011;23(10):715-718
Recently,paclitaxel has been used as a new agent on patients with advanced esophageal cancer,and several studies have demonstrated that paclitaxel and paclitaxel-based regimens have significant activity in patients with advanced esophageal cancer and showed highly response rates than the combination of 5-fluorouracil (5-Fu) and cisplatin.However,there have been some problems which need to be solved such as drug-resistance,side effect,and so forth.The new medicament form of paclitaxel can not only depress poison without anti-allergy but also raise medicament curative effect as well as the pharmacal concentration.Although most of the research on the new medicament form of paclitaxel are still limited in the stage of laboratory,it has possessed potential advance in the treatment of advanced esophageal cancer.
10.A clinical study of interventional therapy for liver metastases from colorectal carcinoma
Journal of Interventional Radiology 2001;0(06):-
Objective To evaluate the efficacy and prognostic factors in patients with liver metastases from colorectal carcinoma treated by interventional therapy.Methods Follow up information of 80 patients with liver metastases from colorectal carcinoma were analyzed. The survival time and parameters were likely to affect the prognosis revealed by statistical methods. Results It was shown that the over all 0.5,1,2,3year survival rates were 100%,75.8%, 31.5% and 10.8% respectively. Univariate analysis showed that the age, the volume ratio of the tumors/liver, abundance of the tumor vessels, the retention of the lipiodol, resection of the original lesion and the difference of the tumor sizes between pre therapy and post therapy were the significant prognostic factors. Multivariate analysis showed that abundance of the tumor vessels and the difference of the tumor sizes between pre therapy and post therapy were the most significant factors. Conclusions The hepatic arterial infusion chemotherapy and embolization are effective to patients with liver metastases from colorectal carcinoma proportionately to the tumor vascular abundance and primary lesion resection.
