Objective To investigate the value of diffusion weighted magnetie resonance imaging and apparent diffusion coefficient (ADC) value in the diagnosis of pancreatic cancer.MethodsThe clinical data of 36 patients with pancreatie cancer who were admitted to the Wuxi No.2 People's Hospital from March 2009 to June 2011 were retrospectively analyzed,and the clinical data of 30 healthy volunteers were collected.All candidates received diffusion weighted magnetie resonance imaging examination.The signal intensity ratios ( SIRs ) of the cancer and the pericancerous tissues in the T1 weighted-images (T1WI),T2 weighted-images (T2WI)and diffusion weighted-images (DWI) were compared by using one-way analysis of variance.The ADC values of the cancer and the paricancerous tissues were compared using the paired t test.The differences of the ADC values of the cancer and pericancerous tissues compared with those of healthy individuals were analyzed using an independent sample t test.ResultsThe accuracy rate of preoperative magnetic resonance imaging examination was 92％.The relative SIRs were 0.203 ± 0.190 in the T2 WI,0.399 ± 0.201 in the T1 WI and 0.579 ± 0.291 in the DWI,respectively,with no significant differences across the 3 kinds of images (F=5.92,6.15,6.83,P ＜ 0.05 ),while SIRs of the T1 WI and DWI were significantly higher than that of the T2 WI ( P ＜ 0.05 ).There was no significant difference in SIRs when comparing T1 WI and DWI ( P ＞ 0.05 ).The mean ADC values of the cancer and pericancerous tissues of the pancreatic cancer patients and the pancreatic tissues of healthy individuals were (1.40±0.24) ×10 3 mm2/s,(1.71 ±0.10) ×10-3 mm2/s and (1.73±0.30) ×10-3 mm2/s,respectively,with significant differences across the 3 modes of images (t =10.54,12.08,P ＜ 0.05).ConclusionDWI can show high quality images of the lesions,and ADC value is helpful in the diagnosis of pancreatic cancer.

To make a systematic analysis on literatures concerning traditional Chinese medicine (TCM) advices in Treatise on Febrile Diseases, and summarize the main connotations of traditional Chinese medicine advices, relevant TCM advices in Treatise on Febrile Diseases were collected, screened, compared, summarized and analyzed according to TCM dosage form preparation methods, TCM administration methods, medication contraindications and nursing after TCM administration. The literatures concerning medications in Treatise on Febrile Diseases were consulted, summarized and compared to standardize medicine advices and facilitate rational clinical application of TCMs. The standard medicine advices were as follows. The boiling water for TCMs shall be tap water and well water. The decoctions that have effects in promoting blood and meridians can be boiled with wine. The decoctions containing toxic components can be boiled with honey. Some TCMs shall be boiled with special methods, e. g. Herba Ephedra that could be boiled before other medicine and skimmed. Japonica rice could be added in decoctions to measure the duration of decoctions. Different dosages were required for different forms (litre, pill, medicine spoon). Administration times, temperature and frequency shall be adjusted according to target positions, functions and stage of illness. As for dietary contraindications during medication, thick porridges are recommended, where foods impacting medicine efficacy are prohibited. Regarding nursing after medication is important to recover physical functions, particularly warm porridges can go with diaphoretic recipes, while thick porridges can go with purgative recipes. And drug efficacies shall be defined by observing urine and excrements, and blood form. In conclusion, Treatise on Febrile Diseases is the first book that discusses TCM advices and records them in details. In this study, new standard medicine advices were proposed to provide important basis for improving clinical advices of TCMs and supports for developing the TCM dispensing technology.

Objective: To investigate the application of the calculated electrophysiological parameters in early diagnosis of carpal tunnel syndrome (CTS). Methods: 44 patients (60 hands) with a diagnosis of CTS and 31 healthy volunteers (44 hands) were enrolled. Acquired indicators include median nerve distal motor latency (DML), complex muscle action potential (CMAP) amplitude, conduction velocity (MCV), median nerve sensory nerve action potential (SNAP) amplitude, and conduction velocity (SCV). Then the terminal latency index (TLI), the residual latency (RL), and the difference in peak sensory latencies between the median and ulnar nerves (ΔPSL) were calculated. Results: The two groups were matched in age and gender distribution. The CTS group showed significant difference in SCV, DML, SNAP, and CMAP compared with the control group. The sensitivity, specificity, cutoff value, Youden index, and area under the curve of each indicator are respectively as follows: TLI (0.733, 0.932, 0.622, 0.629, and 0.877), RL (0.750, 0.977, 1.334, 0.727, and 0.907), ΔPSL (0.950, 0.841, 0.150, 0.791, and 0.942), SCV (0.950, 0.796, 56.5, 0.746, and 0.946), DML (0.867, 0.932, 3.55, 0.799, and 0.930), SNAP (0.683, 0.932, 21.68, 0.615, and 0.844), and CMAP (0.683, 0.773, 8.76, 0.456, and 0.758). Conclusion: The calculated electrophysiological parameters have higher sensitivities and specificities relative to a single electrophysiological parameter, which could greatly improve the accuracy of early diagnosis of CTS.

ObjectiveTo investigate the expression and relevant function of protein kinase C (PKC)-α in kidney of rat with chronic arsenic poisoning.MethodsTotally 60 healthy SD rats of clean grade were randomly divided by body weight into 3 groups:high-dose arsenic exposure group (10.0 mg/kg),low-dose arsenic exposure group (0.4 mg/kg),and control group.The rats were exposed by drinking arsenic solution which was mixed with distilled water.Rats were weighed every 10 days and dose volume of arsenic solution was adjusted.After continuous exposure for 4 months,blood and urinary arsenic were determined.Rat kidneys were taken and stained by Immunohistochemistry SABC.PKC-o positive cells in the kidney were observed and counted,and its average gray value was analyzed with image analysis software (Biomias).ResultsProximal tubules PKC-α-positive cell count [(3.62 ± 1.90),(10.07 ± 3.22)/field],glomerular PKC-α-positive cell count [(3.62 ± 1.90),(10.07 ± 3.22)/field]in high and low arsenic group of SD rat kidney were lower than those of the control group [(60.00 ± 9.63),(18.57 ± 2.71/field,all P ＜ 0.05]; both urinary arsenic level[(7366.62 ± 1086.50),(1744.31 ± 300.12)μg,/L]and blood arsenic level [(31.59 ± 9.24),(16.58 ± 2.08)μg/L] in high-dose and low-dose groups were higher than those of the control group [(18.97 ± 3.58),(18.97 ± 3.58)μg/L,all P ＜ 0.05] ; the average gray values of SD rat kidney proximal tubule,glomerular PKC-o positive cells in high-dose and low-dose groups( 142.79 ± 11.16,122.15 ±5.91 ) were higher than that of the control group (114.33 ± 6.70,all P ＜ 0.05).ConclusionsArsenic can decrease SD rat kidney PKC-α -positive cells.The regulatory function of PKC-o in inhibiting cell apoptosis of kidney of rats with arsenic poisoning is weakened.

Background Retinal neovascularization disease is a common cause of blinding.Retinal neovascularization is related to enhancing proliferation of vascular endothelial cells.So how to inhibit proliferation of vascular endothelial cells is a hot burning issue.p21 is known to be involved in the regulation of cell cycle and therefore inhibit the cell proliferation.However,the relationship of p21 and the proliferation of vascular endothelial cells in retinal neovascularization disease is for further study.Objective The aim of this experiment was to study the proliferation of rhesus retinal vascular endothelial cells(RF/6A) and expression of p21 in RF/6A cells under the hypoxia condition,and discuss their association.Methods The RF/6A cells were cultured and passaged in vitro,then they were randomly divided into normoxia culture group(5％ CO2 +95％ O2) and hypoxia for 1 hour,3,6,12 hours group(1％ 02+5％ CO2 +94％ N2).Flow cytometer(FCM) was used to check the distribution of RF/6A cell cycle in the normoxia culture group and hypoxia for 1 hour,3,6,12 hours groups.MTT assay was used to detect and compare the cell proliferation(A570)among the various groups.The expression of p21 in the cells was analyzed by Western blot.Results FCM showed that the cells proportion of G0/G1 stage was reduced initially and then increased afterward in hypoxia for 1 hour and 3,6,12 hours groups,showing a significant difference among 5 groups (F =20.083,P =0.000),and the cells proportion of S stage and G2/M stage were increased firstly and then declined in different hypoxia groups with statistical significances (F =7.861,P =0.001 ; F =10.305,P =0.003).Compared with normoxia culture group,cells proportion of G0/G1 stage was declined and that of S stage and G2/M stage were raised after hypoxia culture,showing statistically signifcant differences(P＜0.05).MTT showed that cell multiplication capacity(A570 value)strengthened firstly and then weakened in hypoxia groups with time prolongation,showing a significant difference among all the groups(F=7.768,P=0.001),and A570 value in hypoxia for 3 hours and 6 hours groups (0.315± 0.062,0.365 ± 0.064) was significantly higher than that of the normoxia group (0.205 ± 0.063),respectively(P＜0.05).Western blot showed that the expression of p21 in the cells down-regulated at the beginning and then up-regulated with the increase of hypoxia time,and there was statistical significance (F =16.738,P=0.000).The p21 relative levels in different hypoxia groups were reduced in comparison with the normoxia group,showing statistical signifcances(P＜0.05).Conclusions Short-term hypoxia could reduce the expression of the p21 in RF/6A and induce cell proliferation initially,then p21 increases and cell proliferation is inhibited with the prolongation of hypoxia time.
