Objective To investigate the relationship between C-reactive protein and clinical significance of Tokyo Guidelines for acute cholangitis.Methods Analyzed 739 cases with acute cholecystitis in Xianyang Central Hospital of Shaanxi province.Records of patients diagnosed with acute cholecystitis were screened between September 2013 and October 2015.The criteria of Tokyo guidelines were used in grading the severity of acute cholecystitis.Patients were divided into 3 groups,Group Ⅰ (n =450),Group Ⅱ (n =260) and Group Ⅲ (n =29).C-reactive protein values at the time of admission were analyzed and compared among the groups.Results Mean C-reactive protein levels of groups were found to be significantly different,18.74 mg/L in Group Ⅰ,133.67 mg/L in Group Ⅱ,and 257.43 mg/L in Group Ⅲ.C-reactive protein values among the groups were found to be highly and significantly correlated with the disease grade (P ＜ 0.01).After evaluating C-reactive protein levels according to the grade of the disease,Group Ⅱ was distinguished from Group Ⅰ with a cutoff C-reactive protein level of 72.54 mg/L,and from Group Ⅲ with a value of 195.85 mg/L.Those results were found to be statistically significant (P ＜ 0.01).Conclusion C-reactive protein can be accepted as a strong predictor in classifying different grades of the disease,and treatment can be reliably planned according to this classification.

Objective To estimate the operational efficiency of 37 county level public general hospitals in Hubei province using the world popular method of Bootstrap-data envelopment analysis.The aim is to make up for the theory and methodology gaps on DEA research for hospitals in China,and to provide policy and management recommendations for their further improvement.Methods The input and output indicators of hospital efficiency evaluation were selected based on our previous research.R Software was used to describe the current input and output indicators,while FEAR package used to measure Bootstrap-DEA efficiency value of the sample hospitals with bias corrected,along with such applied analysis as efficiency benchmarking for the technical efficiency outcomes.Results There are great differences among the healthcare input and output of these hospitals.In particular,the difference in the number of actual beds was 4.67 times between the highest hospital and the lowest one.All of the bias corrected efficiency scores were lower than those before correction,and the average bias corrected score of the sample hospitals is 0.717 9.Moreover,only 20 hospitals(54.05%)have their efficiency scores above the median level.Conclusions The healthcare resources allocation of these hospitals needs to be further optimized.Hospitals still have big potential to improve their efficiency.Besides providing policy support,the government is advised to guide hospitals to innovate their management mechanisms,such as introducing and applying benchmarking,ranking,inter-hospital learning among others,so as to continuously improve their operational efficiency.

AIM To study if cholecystokinin octapeptide (CCK-8) alter cardiovascular functions by its direct inhibitory effect on carotid sinus baroreceptor (CSB) activity. METHODS The functional curve of carotid baroreceptor (FCCB) was constructed and the functional parameters of carotid baroreceptor were measured by recording sinus nerve afferent discharge in anesthetized male rats with perfused isolated carotid sinus. RESULTS ① CCK-8 0.1, 0.5 and 1.0 μmol·L-1 shifted FCCB to the right and downward, with a marked decrease in peak slope and peak integral value of carotid sinus nerve discharge in a concentration-dependent manner, indicating the inhibitory effect of CCK-8 on CSB activity. ② Pretreatment with proglumide (100 μmol·L-1), a nonselective CCK receptor antagonist, or Bay K8644 (0.5 μmol·L-1), an agonist of calcium channel, partially attenuated the inhibitory effect of CCK-8 (0.5 μmol·L-1) on CSB activity. Pretreatment with L-NAME (100 μmol·L-1), an inhibitor of NO synthase, did not affect the inhibitory action of CCK-8. CONCLUSION CCK-8 inhibits CSB activity, which may be mediated by activating CCK receptors in the carotid sinus area and thereby resulting in an inhibition of stretch-sensitive channels and decrease in Ca2+ influx.

Objective To investigate the effect of Curcumin on rats with severe acute pancreatitis associated renal injury and explore the possible mechanisms.Methods A total of 72 rats were randomLy divided into sham-operated group(S group, n =24), severe acute panceratitis with renal injury group(M group, n =24) ,Curcumin-treated group(Cur group,n=24).The S and M groups were given 1.5 ml saline through intragastric administration 3 hours before operation,while the Cur group was fed with same amount of Curcumin diluent(200 mg/kg).The pancreas and pancreatic tail-segment was dissociated and the head of pancreas was occlused in rats to form the model,blood vessel forceps was loosed after 3 hours.All the rats were sacrificed at 12 h,24 h, 36 h and 48 h after modeling.The level of ascites, serum amylase, creatinine, blood urea nitrogen were detected and the pathological chang of pancreas was observed under light microscope.Take the right kidney for Superoxide Dismutase (SOD) determination and the expression of hypoxia inducible factor-1αmRNA in the right kidney was detected with realtime polymerase chain reaction (RT-PCR).Results Compared with Cur group, the level of ascites, serum amylase, creatinine, blood urea nitrogen in M group were significantly increased, but the activity of SOD, the express of hypoxia inducible factor-1αmRNA had a significant decline (P＜0.05).The tissue damage of pancreas and the kidneys became more serious.But a better performance was to be found in the function of the Cur group's kidney and pancreas, and the the difference was statistical significance (P ＜0.05).Conclusion Curcumin has a good protective effect on severe acute pancreatitis associated renal injury.It may be through up-regulation expression of HIF-1α mRNA and increase the activity of superoxidase dismutase, then reduce the cell apoptosis and necrosis of the kidney, improve the ability of the kidney to tolerate hypoxia.

Objective To observe the effects of melatonin on synaptic plasticity impaired by spinal cord injury in rats. Methods A total of 54 female Sprague-Dawley rats were divided into sham group (n=18), control group (n=18) and melatonin group (n=18). Spinal cord inju-ry model was established with modified Allen's method at T10 (10 g from 25 mm height). The number of neurons and the expression of the Nissl body were detected with immunofluorescence and Nissl staining. The expression of neurofilament-200 (NF-200), brain-derived neuro-trophic factors (BDNF), Synapsin I and growth-associated protein-43 (GAP-43) was detected with Western blotting. Results Seven days af-ter injury, the number of motoneurons, the expression of Nissl body in motoneurons, and the expression of BDNF, Synapsin I and GAP-43 decreased in the control group compared with those in the sham group, and they increased in the melatonin group compared with those in the control group. Conclusion Melatonin can repair the impaired synaptic plasticity, which might promote the functional recovery after spi-nal cord injury.

Objective To investigate the effect of rhodiola on severe acute pancreatitis associated renal injury and explore the potential mechanisms.Methods A total of 90 rats were randomly divided into sham-operated group (S group,n =18),severe acute pancreatitis with renal injury group (M group,n =18),low rhodiola dose group (3 g/kg,T1 group,n =18),moderate dose rhodiola group (6 g/kg,T2 group,n=18),high rhodiola dose group (9 g/kg,T3 group,n =18).The S and M groups were given 6 g/kg saline through intraperitoneal injection before operation while the T1 group,T2 group and T3 group were given with 3 g/kg,6 g/kg,9 g/kg dose of rhodiola through intraperitoneal injection,respectively.The pancreas was dissected and the head of pancreas was occluded by blood vessel forceps for 3 hours to make rat model.All the rats were sacrificed at 12 h,24 h,36 h after modeling.The level of ascites amylase,serum amylase,creatinine,blood urea nitrogen,interleukin 1β(IL-1β) and interleukin 10 (IL-10) were detected and the pathological change of pancreas and the left kidney was observed under light microscope.The serum levels of IL-1β and IL-10 were detected by enzyme-linked immunosorbert assay (ELISA).Take the right kidney for superoxide dismutase (SOD) determination and the expression of hypoxia inducible factor-1α (HIF-1α)mRNA in the right kidney was detected by real-time polymerase chain reaction (RT-PCR).Results Compared with the S group,the level of serum amylase,creatinine,blood urea nitrogen and IL-1β in M group increased significantly,but the activity of SOD has a significant decline (P ＜ 0.05).Compared with M group,the level of serum amylase,creatinine,blood urea nitrogen and IL-1 β in T2 group has a significant decline,but the activity of SOD,the express of HIF-1α mRNA and IL-10 has a significant increase (P ＜ 0.05).With the dose of rhodiola increased,the renal and pancreatic function in T2 group had a better performance than T1 group,and the difference was statistical significant (P ＜ 0.05).But compared with T2 group,the renal and pancreatic function in T3 group did not increased significantly (P ＞ 0.05).Conclusions Moderate dose of rhodiola (6 g/kg) has a good protective effect on severe acute pancreatitis associated renal injury.It may be associated with the inhibitory expression of IL-1β,up-regulated expression of IL-10,HIF-1α mRNA,and the increased activity of SOD.So it can then reduce cell apoptosis and renal necrosis,and improve the ability of the kidney to tolerate hypoxia.
