Objective To study the effect of early enteral nutrition(EN) and total parenteral nutrition(TPN) in patients with severe acute pancreatitis by a mata analysis.Methods Randomized controlled trials of TPN and early EN in patients with severe acute pancreatitis were searched in Medline,Pubmed and Embase from Jan 1970 to June 2009,and Cochrane Library(Issue 2,2009).Seven studies were enrolled into the analysis.The detail about the trial design,characters of the subjects and results of the studies were reviewed by two independent authors and analysed by using Revman 5.0.18 software.Results Compared with TPN,early EN was associated with a significantly lower incidence of pancreatic infections(OR =0.38,95% CI :0.18～0.82,P =0.01),organ failure(OR =0.43,95% CI :0.23～0.79,P =0.007),fewer surgical interventions(OR =0.34,95% CI :0.18～0.63,P =0.0006) and mortaily(OR =0.41,95% CI :0.19～0.88,P =0.02).However,there was no significant difference in total infections [ OR =0.43,95% CI(0.17,1.10),P =0.08]between patients with TPN and early EN.Conclusions Early EN could be the preferred nutrition feeding method for patients with severe acute pancreatitis.

Objective To explore early diagnostic methods for ulnar impaction syndrome on the basis of suggested criteria.Methods From December 1998 to December 2004,123 cases complained of ulnar pain.They were checked and diagnosed according to the criteria of Yu-dong Gu,and especially,the results of wrist MRL Forty-eight of them were diagnosed as ulnar impactinn syndrome.A retrospective study was done to analyze the char- acteristies of X-ray and MRI in examining ulnar impaction syndrome,clinical symptoms of the wrist,and the association between Chun & Palmer's scoring systems and imaging manifestations.Results Most of the cases of ulnar impaction syndrome had positive lunar variance (68.8%).Carpal avascular necrosis was found in about 27.1% of the cases through X-ray examination of the wrist,64.7% of whom were lunar osteonecrosis.Abnormal changes in signal intensity occurred in the MRI findings of the syndrome cases.The carpal necrosis was always located at the ulnar side of lunare or (and) at the waist and bottom of triquetrum.There was a close relationship between clinical symptoms and Chun & Palmer's grading systems and carpal imaging,MRI in particular Conclusion Early diagnosis of ulnar impaction syndrome can be made easily on the basis of deep understanding of the syndrome,clinical symptoms,and findings of imaging,especially MRI.

OBJECTIVE: To observe the characteristics of vertical cast-off bloodstain pattern by different hitting-tools. METHODS: The regular hitting tools, a kitchen knife, a dirk, a plane set-hammer and an iron pipe, were selected. At a distance of 30 cm away from the wall, the hitting tool with 5 mL fresh chicken blood made the cast-off bloodstain from top to bottom. Then the holistic distribution characteristics (length, width and density) of cast-off bloodstain and morphology characteristics (length, width and contact angle) of first single cast-off bloodstain were analyzed. RESULTS: The distribution length of cast-off bloodstain formed by dirk was minimum (P < 0.05). The distribution width of cast-off bloodstain formed by kitchen knife was minimum (P < 0.05). Except the pair of kitchen knife and plane set-hammer, the distribution density between each two tools had statistical differences (P < 0.05). The length of first single cast-off bloodstain formed by plane set-hammer was longest compared (P < 0.05). The width of first single cast-off bloodstain had statistical differences between kitchen knife and plane set-hammer, and between dirk and plane set-hammer (P < 0.05). CONCLUSION The type of hitting tool could be inferred by the specific characteristics of cast-off bloodstain pattern formed by every specific type of hitting tool in crime scene.

ObjectiveTo evaluate the protective effect of Xuebijing injection against renal injury in patients with sepsis, and to explore its possible mechanism.Methods A prospective randomized controlled trial (RCT) was conducted in which 62 severe patients with sepsis and septic shock admitted in Department of Critical Care Medicine of Jiangsu Province Traditional Chinese Medicine Hospital from June 2013 to December 2013 were randomly divided into control group and Xuebijing group, with 31 patients in each group. The patients in both groups received basic treatment for sepsis, and the patients in Xuebijing group were additionally given intravenous injection of Xuebijing 100 mL once a day for 7 days. In both groups, the changes in acute physiology and chronic health evaluationⅡ (APACHEⅡ) score were observed before treatment and 1, 3, 7 days after treatment, and the changes in the levels of interleukins (IL-6, IL-10), prothrombin time (PT), fibrinogen (Fib), activated partial thromboplastin time (APTT), serum creatinine (SCr), and Cystain C (Cys C) were determined before treatment and 1 day and 3 days after treatment.Results There was no statistically significant difference in APACHEⅡ score before treatment between two groups, however, the APACHEⅡ scores were significantly decreased in both groups 3 days and 7 days after treatment compared with those before treatment, and the degree of decrease in Xuebijing group was more obvious 7 days after treatment (13.61±7.62 vs. 16.34±8.70,P< 0.05). Serum concentrations of Cys C, SCr, IL-6, IL-10, PT, APTT, and Fib showed no difference between two groups before treatment (allP> 0.05), while after treatment the degrees of improvement of above indexes in Xuebijing group were obviously superior to those in control group, especially 3 days after treatment[Cys C (mg/L):1.12±0.11 vs. 1.35±0.14, SCr (μmol/L): 115.0±31.0 vs. 135.0±24.0, IL-6 (ng/L): 54.27±28.79 vs. 73.35±31.01,PT (s): 13.50±0.11 vs. 15.71±0.11, APTT (s): 43.66±0.31 vs. 48.03±0.55, Fib (g/L): 1.91±0.51 vs. 1.51±0.52, P< 0.05 orP< 0.01].ConclusionXuebijing injection has certain renal protective effect in patients with sepsis, and its mechanism is possibly related to the regulation and improvement of uncontrolled inflammatory response and coagulation function in sepsis.

OBJECTIVETo investigate the protective effects of Yuyin Ruangan Decoction(YRD, traditional Chinese medicine) on experimental hepatic injury in mice.

METHODSThe mice were randomly divided into control group, model group and YRD low, middle and high dose group(n = 11). By ip injection of D-GalN, CCk or thioacetamide (TAA), three models of hepatic injury mice were established to investigate the effects of YRD through detecting the indexes of liver function in serum and, the content of antioxidant system in the hepatic tissue.

RESULTSYRD could decrease the content of alanine aminotransferase (ALT)and aspartate aminotransferase (AST) in serum and that of malonaldehyde (MDA) in the hepatic tissue, upregulate the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in the hepatic tissue. Furthermore, the above effects were dosedependent in a certain degree. CoNCLUSION: YRD has some protection effects on the model of experimental hepatic injury in mouse.
