Objective To investigate the relationship between values of blood calcium, serum urea nitrogen (BUN), D-dimer, C-reactive protein (CRP), fibrinogen and amylase with the severity of the disease in patients with acute pancreatitis (AP). Methods There were 70 patients with mild AP (MAP group), 18 patients with moderate AP (MSAP group), 26 pa?tients with severe acute pancreatitis (SAP group) in 114 AP patients. The laboratory indexes were compared between these groups. The correlation between indexes and the acute physiology and chronic health evaluation systemⅡ (APACHE Ⅱ) score was analysed. The diagnostic sensitivity of SAP using CRP, D-dimer and fibrinogen was analysed by ROC curves. Re?sults Compared with MAP group, values of BUN, CRP, D-dimer,fibrinogen and APACHEⅡscore were significantly increased in SAP group (P<0.05), but serum calcium level was significantly decreased (P<0.05). The APACHEⅡscore were significantly higher in SAP group than that of MSAP group (P<0.05). There were no significant differences in level of amylases between three groups. There was a positive correlation between APACHEⅡscore, CRP, D-dimer and fibrinogen (r=0.407, 0.404 and 0.245, P<0.05). There was a negative correlation between APACHEⅡscore and serum calcium level (r=-0.333, P<0.05). The area under the ROC curve showed a maximum CRP curve for diagnosing SAP 0.752 (95%CI=0.644-0.860). The cut-off value was 74.45 mg/L. The sensitivity was 86.4%. And the specificity was 68.2%. Conclusion Combining with monitoring BUN, blood coagulation index, CRP, serum calcium level and other laboratory parameters was useful to overall evaluate AP patients and improve the prognosis.

Objective To investigate the expression of C-erbB-2 and anti-nuclear antigen Ki-67 in thyroid tumor, and its significance in pathologic diagnosis and prognosis the patient. Methods SP immunohistochemical technique was used to detect the expression of C-erbB-2 and Ki-67 in thyroid tissue of 90 cases of thyroid carcinoma and 20 cases of thyroid adenoma. Results High expression of both C-erbB-2 and Ki-67 in thyroid carcinoma, and their expression was weak in thyroid adenoma. The positive rate of C-erbB-2 expression in thyroid carcinoma was statistically higher than that in thyroid adenoma (48.9% vs 20.0%, P

In order to probe into the role of plasma glucagon in the pathogenesis of NIDDM, the concentrations of fasting blood glucose, serum insulin and plasma glucagon were assayed in 327 subjects with normal glucose tolerance (group Ⅰ), 25 patients with NIDDM (group Ⅱ) and 20 NIDDM patients treated with drugs (group Ⅲ). The levels of blood glucose, plasma glucagon and serum insulin in group Ⅱ were 9. 28?2.30 mmol/L,159. 55?34. 13ng/L and 15. 16?10. 79mIU/L respectively, and were significantly higher than those of group Ⅰ(4. 71?0. 64mmol/L,83.12?12.39ng/L and 10. 43?6. 86mIU/L respectively). The levels of blood glucose and plasma glucagon in group Ⅲ were 7. 15?2. 44 mmol/L and 124. 99?37. 23 ng/L respectively and were lower than those of group Ⅱ, no significant difference in serum insulin levels was noted. Correlation analysis showed that blood glucose had a positive linear correlation with plasma glucagon in the three groups (r=0. 8720,0. 9400,0. 8731,respectively, P

The Campylobacter carrier rate of the bile was 23. 64%,14. 29%,7. 14%,6. 64%,5.88%, 5.55% and 3. 63% in the quails, cats, dogs, pigs, chickens, ducks and oxen respectively. The survival time of Campylobacter in the bile in vitro ranged from 4 to 7 weeks. The Campylobacter carrier rate of the intestinal content was higher than that of the bile in all the domestic animals and fowls. It is believed that the domestic animals and fowls may be an important source of Campylobacter infection in human beings according to our findings.

Objective Thymidine phosphorylase (TP) cDNA was transfected into colorectal cancer cell lines LOVO with the lentiviral vector,the anticancer effeciency of 5'-deoxy-5-fluorouridine (5'-DFUR)and 5-fluorouracil (5-FU) on LOVO cells were evaluated.Methods TP cDNA were transfected into LOVO cell line with the lentiviral vector pLenti6.3_MCS_IRES2-EGFP,and the transfection efficiency was analyzed by flow cytometer and immunohistochemistry.Cells were divided into six groups:LOVO,LOVO-TP,LOVO-control,LOVO + INF-α2a,LOVO-TP + INF-α2a,LOVO-control + INF-α2a.TP protein expression and the relative quantitative analysis for TP mRNA in transfections cells were detected by Western blot and RT-PCR respectively.Volumes of converted 5-FU from either in the medium containing different concentration of 5'-DFUR,in which all cells were cultured,or in cells lysate,were detected by high performance liquid chromatography (HPLC).Results The transfection efficiency of TP cDNA in LOVO cells was 95％.The Mean gray value of TP protein expression in LOVO-TP and LOVO-TP + INF-α2a were 198.15 folds and 243.22 folds higher than LOVO cell,respectively (P ＜ 0.01).The RQ values of TP mRNA expression in LOVO-TP and LOVO-TP + INF-α2a were also 18.56 folds and 59.61 folds higher than wild LOVO cell,respectively (P ＜ 0.01).The IC50 values of 5'-DFUR on LOVO-TP and LOVO-TP + INF-α2a were 1 660 μ mol/L and 813 μ mol/L,respectively,significantly lower than 4 462.59 μ mol/L in wild LOVO (P ＜ O.01).The 5-FU volumes detected from media contained series concentration of 5'-DFUR for culturing LOVO-TP and LOVO-TP + INF-α2a were 2.0-5.3 folds,and 2.9-10.4 folds more than wild LOVO,respectively (P ＜ 0.01).Conclusions Transfected TP cDNA into colorectal cancer cell line LOVO with lentiviral vector increases the expression of TP mRNA and TP protein and the amount of 5-FU converted from 5'-DFUR,enhancing its anticancer effect.

Acupuncture for stroke rehabilitation is of multi-targets, the treatments of which are not only for hemiplegia, but also cover a wide variety of aspects, such as aphasia, dysphagia, dysarthria, cognitive disorders, bowel or bladder dysfunction, ataxia and post hemiple-gic pain, etc. Based on the experiences of stroke rehabilitation with Integrated Traditional Chinese and Western Medicine over 20 years, this paper discussed the selection of acupoints, needling manipulations, opportunity of intervention, quantity of stimulations, the needle-retaining time as well as the impact on spasticity after hemiplegia referring to ancient and modern literatures and modern rehabilitation theory.

Objective To observe the local field potential activity of dorsomedial and dorsolater striatal (STR) neurons in rats with exercise-induced fatigue,so as to explore the regional characteristics of those neurons.Methods Thirty-six male Wistar rats were randomly divided into a control group(CG),a single fatigue group(SFG)and a repeated fatigue group(RFG),each of 12.The exercise-induced fatigue model was established according to a load-increasing treadmill running protocol.The CG did not do any treadmill running,SFG finished one-time exhaustive exercise while the RFG repeated exhaustive exercise 6 times.The extracellular glass microelectrode technique was used to record the spontaneous firing of dorsomedial(n=6)and dorsolateral(n=6)STR neurons in vivo to observe the discharging frequency,characteristics and types.Results (1)Spontaneous firing frequencies of striatal neurons in SFG were significantly higher than those of CG(P＜0.01),while those of RFG were significantly lower than SFG.(2) After repeated fatigues,there were significant decreases in the irregular firing pattern and significant increase in the explosive firing of striatal neurons compared with CG(P＜0.05).(3)After the single fatigue and repeated fatigue,the discharging frequency of dorsomedial medium spiny-like neurons increased significantly(P＜0.05),and that after repeated fatigue significantly higher than that of the dorsolateral(P＜0.01).The discharge frequency of the dorsomedial and dorsolateral fast-spiking neurons decreased significantly after repeated fatigues.The discharge frequency of dorsolateral large aspiny-like neurons of RFG was significantly higher than SFG,while that of the latter was significantly lower than CG(P＜0.05).Conclusions (1)Striatal neurons mediate exercise-induced fatigue and present regional characteristics,which might be due to dorsomedial and dorsolateral striatal neurons receiving different types of projection neurons.(2) Striatal fast-spiking neurons may play an important role in mediating the exercise-induced fatigue.
