The Pareto effect generated in use of journal articles covered in Wiley Online Library ( WOL) , a full-text database developed by China Pharmaceutical University, was analyzed, which showed that the number of WOL-covered source journals in ACIE, SSCI, A & HCI, the number of full-text journals that published SCI-covered papers of our university, the key and strong subjects of our university were the leading factors of Pareto effect gener-ated in use of WOL, studies on Pareto effect are thus of importance for the library in its development of literature resources, data information service and subject service.

Objective To explore the changes and clinical significance of serum human cartilage glycoprotein-39(HC gP39),osteopontin (OPN) and rheumatoid factor (RF) in patients with rheumatoid arthritis (RA).Methods Serum HC gP39,OPN levels were measured by ELISA in 98 patients with RA and 98 healthy controls.Serum RF was detected by nephelometric immunoassay.Results The serum HC gP39,OPN and RF levels of RA group were significantly higher than the healthy control group (t =20.25,32.71,36.34,all P ＜ 0.01),and serum HC gP39,OPN and RF levels in active phase patients were higher than the inactive phase patients (t =24.22,45.62,50.15,all P ＜0.01).The levels of serum HC gP39,OPN increased gradually with the increase of the staging severity(F =18.48,12.36,all P ＜0.05).The serum level of RF was positively correlated with the levels of HC gP39,OPN in patients with RA (r =0.682,0.656,all P ＜ 0.01),the serum level of HC gP39 was positively correlated with the level of OPN (r =0.608,P ＜ 0.01).Conclusion The HC gP39,OPN and RF reflect situation of RA patients and have close relationship with the clinical progression of RA,which can be used as one of important indexes to judge RA activity and different staging.

Objective To assess the courses of evidence-based medicine among graduate students. Methods A sample of 118 graduate students who took the course were surveyed twice by using the same self-designed questionnaire at the beginning and the end of the course.Pre-post comparison was conducted to measure the impact. Results The students were able to grasp the most of the contents of the course,and reshaped their opinions on evidence-based medicine,with which,a positive impact on their medical practice was expected. Conclusion The course of evidence-based medicine for graduate students has resulted in a positive consequence.

AIM: To observe the efficacy of high concentrations of sodium hyaluronate ( 3g/L SH ) for moderate to severe dry eye.
METHODS: Forty moderate to severe dry eye patients were included in the study according to the diagnosis criteria and randomized into two groups. The patients of the trial group received topical administration of high concentration sodium hyaluronate (3g/L), and those of the control group received sodium hyaluronate ( 1g/L ) plus recombinant human epidermal growth factor. The dry eye symptom scores, ocular surface disease index ( OSDI) scores, tear film break-up time ( BUT) , SchirmerⅠ test and corneal fluorescein staining score were evaluated. All the indexes were compared between the two groups 2wk before and after treatment.
RESULTS: There were no significant differences of the indicators between the two groups before treatment. After 2wk treatment, the differences were statistically significant compared to former except for the SchirmerⅠtest. Compared with the control group, the symptom scores and the OSDI scores were lowered. No significant differences were found in the other indicators between these two groups.
CONCLUSION: Topical usage of highconcentrations of sodium hyaluronate (3g/L) is beneficial for remitting the ocular symptoms in moderate to severe dry eyes, and also improve the quality of life of patients.

Objective To observe the effects of dexmedetomidine on inflammatory responses and insulin resistance during cardiac operations with cardiopulmonary bypass(CPB).Methods Fifty patients scheduled for elective cardiac valve replacement with CPB were equally and randomly divided into two groups using a random number table:observation group and control group(n =25).A loading dose of dexmedetomidine 1.0 μg/kg was injected intravenously over 1 5 min after induction,followed by continuous infusion at 0.4 μg·kg-1 ·h-1 until the end of CPB in doservation group.While the e-qual volume of normal saline was given in control group.After induction(T1 ),at 30 min after the be-ginning of CPB(T2 ),at the end of CPB(T3 ),and at 2 h after the end of CPB(T4 ),the jugular venous blood samples were taken for determination of serum concentrations of TNF-a,IL-6,insulin and blood glucose.The insulin sensitivity index (ISI ) = 1/(glucose × insulin )was obtained. Results Compared with control group,the serum TNF-a and IL-6 concentrations at T2-T4 were sig-nificantly decreased in observation group(P <0.05),the serum insulin and blood glucose concentra-tions at T2 ,T3 were significantly decreased in observation group(P <0.05 ),the ISI at T2 ,T3 were significantly increased in observation group(P <0.05).Conclusion Dexmedetomidine can reduce in-flammatory responses,thus reducing insulin resistance and blood glucose during cardiac operations with CPB.

AIM:To investigate the role of JAK-STAT pathway , IL-1βand IL-6 in the PC12 cells with X-ray irradiation.METHODS:The PC12 cells were irradiated with X-ray at doses of 2, 4 and 8 Gy.After 24 h, the levels of IL-1βand IL-6 were detected by ELISA .The protein levels of p-JAK1, p-JAK2, p-STAT1, p-STAT3 and p-STAT5 were measured by Western blot .RESULTS:Compared with control group , the levels of IL-1βand IL-6 increased .The protein levels of p-JAK1, p-JAK2, p-STAT1, p-STAT3 and p-STAT5 increased with the doses of X-ray exposed.CONCLUSION:JAK-STAT signaling pathway , IL-1βand IL-6 play a role in the injury of PC12 cells with X-ray irradiation.

Objective To study the relationship of matrix metalloproteinase 7(MMP7)expression to the infiltration and metastasis of malignant melanoma.Methods Various concentrations(10,20,30 μmol/L)of heparanase antisense oligodeoxynucleotide (ASODN)was used to transfect human malignant melanoma cell line A375.Then,the transfected cells were subcutaneously inoculated into the right back of nude mice.Six weeks after the inoculation,transplanted tumors were isolated from the mice,and the levels of MMP7 protein expression were assessed by SP immunohistochemistry.The expression rate of MMP7 was also examined by SP immunohistochemistry in A375 cells and in tissue samples from patients with malignant melanoma(n=30),iunctional nevus(n=30)and normal human controls(n=15).Results The expression rate of MMP-7 was 83.33%(25/30),6.67%(2/30)and 0(0/15)respectively in malignant melanoma,iunctional nevus and normal skin tissue samples;there was a significant difierence in the positivity rate of MMP-7 between the malignant melanoma group and iunctional nevus group (x2=35.62,P=0.000)as well as normal control group(x2=28.12,P=0.000),but not between the junctional nevus group and normal control group(P＞0.05).The expression of MMP-7 in transplanted tumor was decreased to a varying degreee by three levels of ASODN,and the inhibitory effects of 30 mol/L ASODN were the strongest(P＜0.05).MMP-7 protein was also highly expressed in A375 cells.Conclusions The expression of MMP-7 in cutaneous malignant melanoma is higher than that in iunctional nevus and normal skin tissue.Hpa-ASPDN significantly inhibits the expression of MMP-7 in transplanted tumors in nude mice.MMP-7 is highly expressed in A375 cells.
