Objective: To investigate the effect of vascular endothelial growth factor-C (VEGF-C) on invasive capability and proliferation of human cholangiocarcinoma cells. Methods: The effect of VEGF-C on FRH0201 was assayed by MTT. The cycle pattern and apoptosis was assayed using flow cytometry. The effect of VEGF-C on homotypic adhesion and metastasis in FRH0201 was examined with 3H-TdR infiltration and Boyden chamber. Results: VEGF-C could enhance the proliferation of FRH0201 in a dose and time dependent manner. And VEGF-C could inhibit cell apoptosis significantly. After cultured for 2 hours with 1, 5, 10ng/ml of VEGF-C, there were more cells in the lower chamber than the control group. After 60, 90, 120 minutes induction by 1ng/ml、5ng/ml、10ng/ml, the cells showed significantly lower homotypic adhesion than that of the control group. Conclusions: VEGF-C could enhance the proliferation of FRH0201 and inhibit cell apoptosis. VEGF-C could decrease homotypic adhesion of FRH0201 and might be a cause of the metastasis.

Objective To improve EP9-A2 for Bias estimation among multiple quantitative detection systems within full range of AMR.Methods 40 patients specimens were determined twice for serum total cholesterol by four detection systems(A,B,C and D).With system A served as comparative method,Bias between A and the other three was evaluated according to CLSI EP9-A2 separately.Furthermore,DD(distance from deviation to tolerable error)and its average confidence intervals between every two sys-tem were calculated and compared with zero.The confidence interval of greater than zero was served as criteria for accepting bias between every two system.Results Bias between A and the other three meet the analytical quality specification according to EP9-A2,although that of D system was positive,and those of B and C system were negative.DD between every two system obeyed nor-mality distribution.All biases between every two system wes acceptable except that between B and D,causing of their interval con-taining zero.After correcting of results from system D,Biases between every two system were all acceptable.Plots of confidence in-terval could provide a full range bias assessment within AMR.Conclusion Comparability and Bias estimation in full range of AMR for results between every two system among 3 or more systems could be evaluated by confidence intervals.

Objective:To stimulate the PBMCs of systemic lupus erythematosus patients with recombinant human high mobility group box1 (HMGB1) protein,observe the effect of HMGB1 on the expression of LC3Ⅱ/Ⅰ protein in active lupus nephritis and inactive lupus nephritis patients.Evaluate the effect of recombinant human high mobility group box 1 ( HMGB1 ) on the proliferation of PBMCs in patients with SLE.Methods:Western blot was used to detect the expression of LC 3II/I protein in PBMCs of active lupus ne-phritis and inactive lupus nephritis patients after stimulated by 1 μg/ml HMGB1 for 0,6,24 and 48 h.CCK-8 assay was used to detect the effects of PBMCs proliferation in patients with SLE after 1 μg/ml HMGB1 stimulation 72 hours.The statistical software SPSS17.0 was used to analyzed the results.Results: Western bolt showed an increasing expression of LC 3Ⅱ/Ⅰ protein in SLE patients after stimulated by HMGB1 ( P<0.05 ) , and this effect was time dependent.Compared with inactive lupus nephritis group , the increasing level of autophagy in active lupus nephritis group was more obviously.1 μg/ml HMGB1 could inhibit the proliferation of PBMCs in patients of SLE significantly ( P<0.001 ).Conclusion: HMGB1 may promote autophagy in SLE especially patients with active lupus nephritis and involved in the pathogenesis of SLE and lupus nephritis.Monoclonal antibodies targeting to HMGB 1 or modulators of mam-malian autophagy may provide new way for the treatment of SLE especially LN.

This paper discusses the current situation that care workers in hospice agencies are lack, the staffing is unreasonable, the nursing workers′education degrees are low and are old, and the present situation of the com-prehensive quality is not high. In addition, it analyzes the causes of this status and put forward the corresponding countermeasures from aspects of the medical college education, social voluntary organizations, national political sys-tem construction and hospice agencies.

Objective To explore the clinical significance of FPSA/PSA ratio in the differential diagnosis of prostate carcinoma(Pca) and benign prostate hyperplasia (BPH). Methods The concentrations of FPSA and PSA in 52 patients with Pca or BPH were analysed retrospectively to calculate FPSA/PSA ratio. Results FPSA/PSA ratio between the Pca and BPH was markedly different (t=4 01,P

OBJECTIVE To investigate the causes and preventive measures of postoperative pneumonia due to cervical part and upper thoracic part esophageal carcinoma surgery. METHODS Fifty seven cases with cervical part or upper thoracic part esophageal carcinoma from 2001 to 2005 were studied restropectively. RESULTS One patient died of aspiration pneumonia,one died of anastomotic leakage,and three died of adult respiratory distress syndrome(ARDS).The tracheotomy and mechanical ventilation were applied.Pneumonia was confirmed among sixteen patients at different degree. CONCLUSIONS Many causes contribute to postoperative pneumonia on patients with cervical part or thoracic part esophageal carcinoma,and the lesion of recurrent nerve is an important reason.Protection of recurrent nerve may decrease postoperative pneumonia.

Late in-the-bag dislocation of intraocular lens bag complex is a rare but potential complication after cataract surgery,which can affect the quality of patients'life seriously,and usually need surgical treatment.People are paying more attention to this complication,because it has been reported with increasing frequency in recent years.This complication may present after a long time frame.There is a research showing that the interval between cataract surgery and the dislocation was 10.9 years.The cumulative risk of IOL dislocation at 10 years,20 years,and 25 years after cataract extraction was 0.1％,0.7％,and 1.7％ respectively.Late in-the-bag IOL dislocation is a result of progressive zonular dehiscence up to many years after cataract surgery,and its genesis is multifactorial.This article reviews the incidence,possible mechanism and risk factors of late in-the-bag IOL dislocation.

102 cases of Tourette's syndrome were divided into three types of the liver and kidney yin deficiency, phlegm and damp blockage and spleen and stomach deficiency.Acupuncture, auricular-plaster therapy, cupping therapy and herbal medicine were combined to treat this syndrome. As a result, 30 cases were satisfactorily effective, 61 cases were improved and 11 cases were ineffective with a total effective rate of 98.2% and no side effects were noticed during treatment.

ObjectiveTo investigate the treatment and safety of interferon ? plus Ribovirin for chronic hepatitis C after kidney transplantation. MethodsFive patients with chronic hepatitis C after kidney transplantation were administered with interferon ? (50 ?g) subcutaneously once a week, plus Ribovirin (600 mg) orally once daily. The levels of HCV-RNA, ALT and serum creatinine in patients’ serum were monitored monthly. ResultsFour in 5 patients presented normal ALT and negative HCV-RNA in serum 12 weeks after treatment, and obtained sustained viral response 24 weeks after interferon ? plus Ribovirin therapy. During treatment, renal graft rejection did not occur. The most frequent side-effects were the decrease of leukocyte and hemoglobin, myalgia and fever, but did not influence the course of treatment. ConclusionCombination of interferon ? with Ribovirin can be a valid therapeutic option in renal transplant recipients with hepatitis C, and shows no influence on the renal function.

Objective To study the relationship between neurodevelopment and early nutritional status of very low birth weight(VLBW)infants in NICU.Methods VLBW infants admitted to NICU of our hospital from January 2013 to December 2014 and received regular follow-up management at our high-risk infant outpatient clinic were retrospectively studied. All infantsˊdevelopmental quotient ( DQ) were evaluated at 3 months of corrected gestational age ( cGA) . DQ ≥130 was defined as excellent, 115-129 above medium, 85-114 medium, 70 -84 below medium and ≤69 abnormal. According to their DQ scores, infants were assigned into two groups, normal neurodevelopment group ( DQ≥85 ) and abnormal neurodevelopment group ( DQ<85 ) . Nutritional status during hospitalization between the two groups were compared.Results A total of 125 VLBW infants were recruited.At three months of cGA, 2 cases ( 1. 6℅) had excellent DQ score; 3 ( 2. 4℅) above medium; 63 ( 50. 4℅) medium;57 (45. 6℅) below medium. 68 cases (54. 4℅) in the normal development group and 57 (45. 6℅) in the abnormal group. The total energy intake, the proportion of enteral energy supply on 4 d, 7 d, 14 d after birth and amino acid supply on 4 d, 7 d were significantly higher in the normal neurodevelopment group than the abnormal group (P<0. 05). Comparing with the abnormal group, weight loss of VLBW infants in the normal neurodevelopment group was less; the time needed to reach birth weight and exclusive enteral nutrition in the normal neurodevelopment group was shorter. The differences were statistically significant between the two groups(P<0.05).Conclusions VLBW infantsˊearly nutritional status may influence their neurodevelopmental outcome.
