Objective To investigate the possible association between vascular endothelial growth factor (VEGF), endostatin (ES) and type 2 diabetic nephropathy. Methods The level of serum VEGF and ES were measured by ELISA in eighty type 2 diabetic patients including thirty subjects without diabetic nephropathy , twenty with microalbuminuria and thirty with macroalbuminuria, and the correlation was analyzed. Results The level of serum VEGF and ES in patients with macroalbuminuria were both significantly higher than that of patients with and without microalbuminuria (P < 0.05). The level of serum VEGF and ES in patients with microalbuminuria were significantly higher than that of patients without diabetic nephropathy (P<0.05). Both VEGF and ES level were positively correlated with the level of microalbuminuria (mAlb) (r=0.226, P<0.01; r=0.491, P<0.01), and negatively correlated with the level of estimated glomerular filtration rate (eGFR) (r=-0.237, P<0.05;r=-0.620, P<0.01). There was a significantly positive correlation between VEGF and ES in patients with microalbuminuria and macroalbuminuria (r1=0.633, P1<0.01; r2=0.532, P2<0.05). However, there was no correlation between VEGF and ES in patients without diabetic nephropathy (r3=0.175, P3>0.05). Conclusion The levels of VEGF and ES in type 2 diabetic nephropathy had varying degree of increasing in different diabetic nephropathy stage , and closely related to mAlb and eGFR. Disequilibrium of VEGF and ES may speed up the progression of diabetic nephropathy.

Objectives To learn the effect of self-recognition-based healthy management on community diabetics. Methods A total of 40 community diabetics were evaluated and trained for 3 months.SPSS11.5 software was used for data analysis. Results At 3 months, some risk factors of diabetes,including body weight, body mass index (BMI), waist circumstance (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP) and 2 h postprandial blood sugar (PBS), were improved (P ＜0. 05). Male patients showed statistically significant reduction in body weight, BMI and WC ( P ＜ 0. 05 ).However, female subjects were found to have significant decline in body weight, BMI, WC, SBP and DBP (P＜0. 05). Those ＞60 year-old had significantly decreased body weight, BMI, WC, SBP, DBP and 2 h PBS ( P ＜ 0. 05). Lower levels of WC, SBP and triglyceride were seen in individuals ＜ 60 year-old ( P ＜0. 05 ). Conclusion Self-recognition-based healthy management could effectively reduce diabetic risk factors and prevent the development of diabetic complications.

OBJECTIVETo study the radiosensitizing effect of resveratrol on hypopharyngeal carcinoma cell line FADU in vitro.

METHODSHypopharyngeal carcinoma cell line FADU was cultured in in vitro DMEM. Its inhibition on cell proliferation was detected using cytotoxicity test (MTT assay). The cell survival curve was drawn using clone formation to obtain sensitive enhancement ratio (SER). Changes of the cell cycle and cell apoptosis were analyzed using flow cytometry (FCM).

RESULTSResults of MTT showed the inhibition of resveratrol on FADU cells increased along with its concentrations (P < 0.05). Results of clone formation indicated the surviving fraction at 2 Gy (SF2) was 0.717 ± 0.062 in the irradiation group, and 0.426 ± 0.035 in the resveratrol plus irradiation group (with SER ranged 1.684 ± 0.178) with statistical difference (P = 0.007). Results of FCM showed that after radiation of 4 Gy radiation, cells at G2/M phase arrest increased, but cells at G1 decreased. After radiation of resveratrol for 24 h, cells at G1 decreased, but cells at G2/M phase and S phase arrest increased. When 4 Gy radiation combined resveratrol was used, cells at G2/M phase arrest significantly increased, but cells at G1 significantly decreased. The apoptosis rate was 1.94% ± 1.65% in the control group, 4.56% ± 0.92% in the irradiation group, 2.03% ± 1.46% in the resveratrol group, and 23.11% ± 7.22% in the resveratrol plus irradiation group. There was statistical difference between the resveratrol plus irradiation group and the rest 3 groups (P < 0.05).

CONCLUSIONResveratrol could enhance the radiosensitivity of hypopharyngeal carcinoma FADU cells in vitro possibly by inducing cell apoptosis and causing changes in the cell cycle distribution.

Objective To analyze the expression of molecular biological markers in patients with early stage adenocarcinoma of lung and to determine the correlation between combined expression and prognosis. Methods Pathologic specimens were collected from 68 patients of early stage adenocarcinoma of lung in our hospital between 2000 to 2002. A panel of molecular markers, including Ki-67, Her-2, P16, P53, VEGF, MMP-9 and CD44v6, were chosen for immunohistochemical analysis of the tumor. Cox proportional hazards regression analysis was used to ana-lyze the relationship between expression of these factors and prognosis. Results Muhivariable analysis demonstrated significantly elevated risk for the following molecular markers: P53 (RR=3.228,95.0% CI 1.331-7.828, P=0.010),MMP-9(RR=2.071,95.0% CI 1.062-4.036,P=0.033),VEGF (RR=2.577,95.0% CI 1.124-5.908, P=0.025). The survival period in the patients with combined expression was remarkably shortened. Conclusions Combined evaluation of P53, VEGF and MMP-9 has clinical significance to the prognosis of early stage adenocarcino-ma of lung.

OBJECTIVE:To provide reference for rational use of TCM injections. METHODS:Among the inpatients who used TCM injections in 4 hospitals of Shanghai Jiading district in 2013,100 cases were collected by systematic sampling in each hospital separately, and the data were analyzed retrospectively. RESULTS:The varieties and amount of TCM injections for blood-activating and stasis-resolving both occupied the first place. 22% inpatients used two or more TCM injections at the same time. The proportion of overdose use of TCM injections reached 54.55%. The type of unreasonable drug use mainly included drug use against differentiation of syndromes,super indications drugs and solvent error. Combined use of TCM injections with same ef-fect accounted for 20.45% of combined use of TCM injections. CONCLUSIONS:It is effective means to improve rational drug use that great impertance paid for clinical use of TCM injections.

Objective To construct recombinant Mycobacterium smegmatis vaccine expressing Cysticercus cellulosae cC1 anti-gen. Methods The recombinant pET28a-cC1 plasmid was extracted and double digested by Xho I and BamH I restriction en-zymes,and shuttle plasmid pMV261 was extracted and double digested by Hind III and BamH I restriction enzymes. Both frag-ments were modified by Klenow fragment to form blunt end,then the large fragments of cC1 and pMV261 plasmid were purified and ligated by T4 ligase enzyme. The recombinant pMV261-cC1 plasmid was constructed and sequenced. Then the pMV261-cC1 plasmid was transformed into Mycobacterium smegmatis by the electrotransformation method. The recombinant cC1-Mycobacterium smegmatis was induced by heat and identified by the Western blotting method with the sera of cysticercosis patients. In addition, the growth states of the Mycobacterium smegmatis and the recombinant cC1-Mycobacterium smegmatis were compared and the growth curves were drawn. Results The restriction enzyme and sequencing results showed that the recombinant pMV261-cC1 plasmid was successfully constructed. After heat induction,a 40 kD band was showed by PAGE analysis of cC1-Mycobacterium smegmatis. The Western blotting results showed that the sera of cysticercosis patients could recognize the 40 kDa band,which sug-gested that cC1 protein was expressed in Mycobacterium smegmatis. Compared with the Mycobacterium smegmatis,the recombi-nant cC1-Mycobacterium smegmatis showed no significant difference in proliferation characteristics. Conclusion The recombi-nant cC1-Mycobacterium smegmatis vaccine has been successfully constructed.

Objective To investigate the antagonistic effect of ω-3PUFAs on cognitive impairment in MK-801-induced schizophrenia (SZ) rats and its mechanism.Methods Rat model of schizophrenia was induced by MK-801.Morris water maze was used to detect the change of cognitive function in rats.The number of neonatal neurons in hippocampus was detected by Brdu staining.CREB,p-CREB,BDNF,TrkB and p-TrkB levels were detected by Weston Blot.Results MK-801 induced schizophrenia-like cognitive impairment (the escape latency in the water maze test was (6.51±3.10)s for Ctr group,(15.27±6.20)s for Mod group;acrossing times was (4.63±1.06) times for Ctr group,(2.00±1.15) times for Mod group),reduced the number of neonatal neurons in hippocampus (the relative level of neonatal neuron number per unit area,Mod/Ctr was 0.656±0.066) and impaired the CREB/BDNF/TrkB pathway (the relative level of gray value,Mod/Ctr:CREB was 0.393±0.065,p-CREB was 0.591±0.015,BDNF was 0.716±0.115,TrkB was 0.787±0.029,p-TrkB was 0.586±0.013).ω-3PUFAs improved the CREB/BDNF/TrkB pathway activity by increasing CREB and TrKB level and their phosphorylation (the relative level of gray value,Pre/Ctr:CREB was 1.139±0.111,p-CREB was 0.845±0.243,BDNF was 0.864±0.133,TrkB was 0.916±0.022,p-TrkB was 0.952±0.047),and then recovered the number of neonatal neurons in hippocampus (the relative level of neonatal neuron number per unit area,Pre/ Ctr was 1.183±0.101),thereby reduced the cognitive dysfunction in schizophrenia rats(the escape latency in the water maze was (7.44±4.55)s for Pre;acrossing times was (3.86±1.68) times for Pre).Conclusion ω-3PUFAs can relieve the MK-801-induced schizophrenia-like cognitive impairment.
