Objective To evaluate the effect of the Danhong injection combined with irbesartan in treatment ofearly diabetic nephropathy. Methods 64 patients with early diabetic nephropathy were randomly divided into two groups and the control group 32 cases,two groups were given control of blood sugar and ensure water and electrolyte balance,support therapy,in which 32 cases were also observed red Danhong injection,Ecuador irbesartan treatment,2weeks before evaluation. Results The total effective rate in treatment group was higher than the control group( x2 =6.38 ,P ＜0. 05) ,after 12 weeks of treatment,two groups of urinary protein decreased significantly compared with before treatment, including observation of urine protein was ( 0. 6± 0. 1 ) g/24h, the control group was ( 0. 7 ± 0. 3 ) g/24h,and decreased urine protein level of the observation group was better than the control group( t = 2. 74,P ＜ 0. 05 ). And in the course of treatment, side effects and serious adverse events were not found. Conclusion Danhong injection combined irbesartar, could improve the clinical symptoms, reduce microalbuminuria in treatment of early diabetic nephropathy is worthy of wider application.

Objective To study the professional value of freshman who specializes in nursing in college,which can help us to take effective strategies to help nursing students form correct and steady professional value.Methods 208 nursing students in college were investigated with nursing professional value questionnaire.Results The total score of the professional value of freshman was (124.53±3.41)points,and caring was (32.41±1.39) points,trust was (22.98±1.64) points,justice was(26.66±l.55) points,profession was (19.73±1.27) points and behaviorism was (22.94±1.31) points among the professional value.Compared with the female nursing students,the scores of the professional values in trust,justice and behaviorism were lower in male,and the score of trust dimension was significantly lower.But the score of the item “Patients have the right to accept or refuse treatment and caring” in justice was significantly lower in female nursing students than male.Conclusions The professional value of nursing students were not optimistic,especially in male nursing students.So colleges and universities need to find effective ways to enhance the training of the professional value of nursing students.

Objective To investigate the effect of pioglitazone on the expression of thrombospondin-1(TSP1)and transfor ming growth factor-β1 (TGF-131)in the kidney of diabetic rats.Methods Forty Sprague-Dawley(SD)rats were randomly divided into 4 groups:normal control(NC),streptozocin-induced diabetic mellitus(DM),diabetic rats treated with pioglitazone(DP)and normal control rats treated with pioglitazone(NP).24-h urine protein quantity,serum creatinine(Scr) and kidney hypertrophy index were measured after treatment for 10 weeks,and the expression of TSP1 and TGF-β1 in the kidney was detected by using RT-PCR and immuohistochemistry.Results As compared with DM group,urine protein level and kidney hypertrophy index were significantly attenuated in DP group(P<0.05),but there was no significant difference in plasma glucose between them(P>0.05).As compared with NC and NP groups,the expression of TSP1 and TGF-β1 was significantly elevated in the kidney of DM and DP groups(P<0.01).Both TSP1 and TGF-β1 expression in DP group was lower than in DM group(P<0.05).Conclusion Pioglitazone can exert a direct protective effect on the kidney in diabetic rats,which is independent of the role of insulin sensitizer,and the mechanism may be associated with the decreased TSP1 expression in the kidney.

A new sonographic pattern of fetal hydrocephalus-midline-waved sign, and its mechanism were reported in this paper. When the abdominal wall of the pregnant woman was percussed by hand during ultrasound examination, the wave of midline echo was observed on sonoimage. The diagnosis of hydro-cephalus was made by this sign in all 12 fetuses, and confirmed by autopsy. No dilatation of the cerebral ventricle was observed in 5 out of 12 fetuses. It would be difficult to make the diagnosis of hy-drocephalus would previous diagnostic criteria be used. This sign is negative in normal fetuses, therefore-this finding has the practical value in the early and differential diagnoses of hydrocephalus.

Objective To determine the relative molecular weight(M_r) of polysaccharide-2b of moutan(PSM_(2b)) to establish the standard of reference substance.Methods PSM_(2b) was separated by a Sepharose 4B column and then PSM_(2b-A) and PSM_(2b-B) were obtained after cryodesiccation.Then HPLC was used to determine their M_r.Ultrapure water was used as mobile phase to compare with 0.7% Na_2SO_4 solution.Results PSM_(2b-A) was pure.The M_r and polydispersity(D) of PSM_(2b-A) obtained by use of dextran as standard were 3.596 2?10~(5) and 4.15 in 0.7% Na_2SO_4 solution phase,respectively,and in ultrapure water phase the M_r and D were 4.758 5?10~(5) and 1.03,respectively.Conclusion Different results are detected by different mobile phases in determination of M_r and D of PSM_(2b-A) by HPLC.And the ultrapure water as mobile phase is more suitable than 0.7% Na_2SO_4 solution.

Objective To discuss manifestations of neurogenic tumors on chest wall on CT imaging and pathology.Methods 7 patients with neurogenic tumors on chest wall confirmed surgically and pathologically were reviewed.To facilitate differential diagnosis,3 cases of malignant sarcoma were reviewed for their features on CT.Results 4 out of 5 cases of neurinoma were benign,with one case showing even density on plain CT scan,3 were poorly even,one case showed obvious evenness after enhancement,and 1 case was poorly evenly enhanced,2 benign cases had compression absorption of surrounding bone of scapula or ribs.One case of moderate malignancy was uneven in plain scan and slightly enhanced after enhancement procedure,and neighboring bone of scapula and rib were compressed and destroyed and absorbed,and neighboring muscular interspace and upper mediastinum were involved.One case showed single lesion of neurofibroma,displaying relatively even density on plain scan and moderate unevenness after enhancement procedure,as well as compression and absorption of neighboring ribs.One case of neurofibroma had multiple lesions,showing uneven density on plain scan.This case did not undergo enhanced scan.The remaining 3 cases were all sarcoma including 2 cases of fibrosarcoma and one case of synovial sarcoma.Conclusion Mass of soft tissues that are situated on chest wall or paravertebral area and with smooth edge are suggestive for benign neurogenic tumor.On the contrary,rough edge and coarse shape and infiltration into neighboring tissues are characteristic for malignant ones.

Objective To explore the signal mechanism of proliferation stimulating effect of connec-tive tissue growth factor (CTGF) on hypertrophic scar (HS) derived fibroblasts. Methods <'3>H-TdR in-corporation technique was used to determine the proliferative effect of CTGF at different concentration. Western blot was applied to semi-quantitively analyze the expression of phosphorylated and total ERK1/2 protein after 0, 5, 10, 15, 30, and 60 min of CTGF stimulation, and the relative value of which was de-fined as AI to measure the activation of ERK1/2 signal pathway. PD98059 was admitted to specifically block the ERK1/2 pathway, and subsequently cell proliferation stimulated by CTGF was studied by MTT. Results CTGF could stimulate fibroblasts proliferation with a dose-dependant manner, and activa-ted the ERK1/2 signal pathway, and AI built up to 0.209±0.0201, reaching the apex at 15 min after stimulation performed. Inhibition of ERK1/2 activation by PD98059 suppressed CTGF-mediated HS fi-broblasts proliferation significantly, while OD significantly dropped. Conclusion CTGF induces a prolif-erative response in HS fibroblasts, and this action is mainly dependent on the activation of ERK1/2 signal pathway.

Objective To study the effect of hidden curriculum on the professional value of nursing students in higher education.Methods A total of 300 full-time nursing students in higher education were collected by the cluster sampling method.They were divided into experimental group and control group by natural class lottery method with 150 students each.The students in experimental group accepted the hidden curriculum such as administrator working of nursing students training,simulated the candidates and the volunteer activities.Then the professional value of the 2 groups was evaluated with nursing professional value questionnaire.Results The total score of the professional value in experimental group after intervention was (126.38±3.29) scores,and caring was (32.50±1.20) scores,trust was (24.40±1.59) scores,justice was (25.54±1.55) scores,profession was (19.64±1.26) scores and behaviorism was (24.31±1.30) scores.The total score of the professional value in control group after intervention was (123.62±2.76) scores,and caring was (32.51±1.24) scores,trust was (22.36±1.30) scores,justice was (26.47±1.54) scores,profession was (19.80±1.23)scores and behaviorism was (22.54±1.59) scores.The scores of trust and behaviorism in experimental group were higher than those in control group,and there were significant differences,t=2.813,2.441,P＜0.05.Conclusions Nursing students of college have positive professional values.The hidden curriculum can cultivate the nursing students' trust and positive psychological quality in higher education.And thus it can be reasonably used in teaching,which would produce a more proactive effect in higher education.

Different human thyroid carcinoma cell lines were treated with all-trans retinoic acid(RA). RA could inhibit cell growth,improve iodide uptake and increase some thyroid specific genes and retinoid acid receptor(RAR)mRNA expressions in FTC-133 cells.However,RA had no effect in C643,HTH74 and XTC. UC1 cells.These findings indicate that different thyroid carcinoma cells display diverse responses to RA.
