Objective To observe the therapeutic effect of Dan-Shen Injection in the treatment of acute pancreatitis. Methods Forty-two cases of acute pancreatitis were classified into 2 groups randomly. The control group was given routine treatment. The therapeutic group was given with routine treatment combinat-ing with Dan-Shen Injection. Results The number of normal WBC cases within 7 days was more in the therapeutic group than that in the control group (P < 0. 05). The recover time of amylases in blood was shor-ter in the therapeutic group than that in the control group (P < 0. 05). The incidence rate of complication, the operative rate and the mortality in the therapeutic group were lower than that in the control group (P <0.05). Conclusion In the treatment of acute pancreatitis, Dan-Shen Injection can enhance the therapeutic efficacy, shorten the course of treatment and reduce the incidence rate of complication and the mortality.

Objective To discuss the value of Duke treadmill score in the diagnosis of coronary heart disease.Methods 94 inpatients underwent treadmill test and coronary angiography,the relationship between the Duke treadmill score and the results of coronary angiography was analyzed.Results The prognostic accuracy and positive predictive value of Duke treadmill score to male and female were 88.9％,85.0％ ;those of traditional electrocardiogram ST standard were 89.6％,82.5 ％,the differences were significant (x2 =4.27,P ＜ 0.05).Conclusion The Duke treadmill score is much more significant than the traditional ST standard in the prognostic accuracy and positive predictive value of diagnosing coronary heart disease.

Objective To investigate the expressions of estrogen receptor (ER) and progesterone receptor (PR) in different tumor tissues of invasive ductal carcinoma(IDC) of the breast. Methods A total of 32 cases of IDC samples were collected. ER and PR expressions in 4 different sites of every sample were measured by immunohistochemical(IHC) assays. Results Overall, a high concordance in both estrogen receptor and progesterone receptor expressions are observed between different tumor tissue sites. The best Kappa values were 0.789 and 0.810 for ER and PR expression respectively. The worst Kappa values were 0. 563 and 0.672,respectively. Conclusion ER and PR expression is not significantly different in different tumor tissues of the same IDC sample. Repeated testing in different tumor tissue sites has little contributions in clinical settings.

Objective We established a model of human breast cancer in nude mice, to discuss the feature of pathology and biology of breast cancer,and give help to establish tools of pathogen research. Methods Human breast cancer cells MCF-7 were subcutaneously injected into the right armpit of nude mice to establish human breast cancer models.The mice were divided into composite group, estrogen group, leptin group and the blank group (30 in each). In the composite group,estrogen and leptin were injected into peripheral region of the tumor daily.In the estrogen group,estrogen was injected.In the leptin group, leptin was injected.In the blank group, physiological saline was injected.Tumor growth was observed, and the volume of the tumor was recorded.The tumor tissues obtained from the mice were pathologically examined. Results (1)The tumor-taking rate of leptin group and the blank group were 46.7% (14/30)and33.3% (10/30) ,and the mode is failure.In composite group and estrogen group they were 96.7% (29/30) and 70% (28/30).There was not significant difference between them ( P < 0.05).(2) The differences of average diameter and volume were statistically significant between the composite group and the estrogen group (P < 0.05).(3) Pathology diagnosis was invasive ductal carcinoma. Conclusions (1) Establishing human breast cancer model in nude mice need the stimulation of estrogen. The tumor-taking rate of nude mice has no relationship with leptin.(2) In the study in vivo, leptin as same as estrogen has stimulating effect on MCF-7 cells proliferation.(3) The transplanted cancer cell partly have the pathology and biology features of the human breast cancer cells and give help to establish tools of pathogen research.

Objective To compare the advantages and disadvantages of non-irrigation and irrigation in the surgical approach of chronic subdural hematoma (CSDH),thus to provide reference for clinical treatment of CSDH.Methods Clinical data of 102 patients with CSDH were retrospectively analyzed.According to the different operation methods,the patients were divided into the non-irrigation group(52 cases) and the irrigation group(50 cases).The blood loss during the procedure,operative time,length of stay and postoperative complication rate between the two groups were compared,and the causes of postoperative complications were analyzed.Results The blood loss during the procedure,operative time and length of stay in the non-irrigation group were (6.73 ± 1.17) mL,(15.06 ± 2.64) min and (10.74 ± 2.20) d,respectively,which in the irrigation group were (19.52 ± 3.18) mL,(38.54 ± 6.95) min and (10.44 ± 2.07)d,respectively,there were statistically significant differences between the two groups in the blood loss during the procedure and the operative time (t =-27.11,-22.72,all P ＜ 0.05),there was no statistically significant difference between the two groups in the length of stay (t =0.70,P ＞ 0.05).The incidence rates of postoperative complication in the non-irrigation group and irrigation group were 8.00％ and 7.69％,respectively,there was no significant difference between the two groups (x2 =0.003,P ＞ 0.05).Conclusion Each of the two methods has its own advantages and disadvantages in the treatment of CSDH.Compared with burr hole irrigation,burr hole non irrigation has the advantages of less blood loss and shorter operative time.However,burr hole non-irrigation is more likely to suffer serious complication.We should select suitable surgical approach by the specific circumstances of the patients.The causes of postoperative complications of CSDH are varied.In particular,there is an important relationship between the non-standard operation and postoperative complications.

Objective To investigate the effects of the exercise training on the cognitive function ,choline acetyltransferase (ChAT) activity and acetylcholinesterase (AchE) activity in stroke prone spontaneously hypertensive rat (SHR/SP) vascular de-mentia model .Methods 30 male SHR/SP rats were randomly divided into sham operation group ,model group and exercise group (n=10) .The VD model was established by the fractional ligation of bilateral carotid artery (2-VO) .The sham operation group and the model group were given the normal feeding without intervention after operation ;the exercise group adopted the treadmill exer-cise(DSPT-1) for 8 weeks .After the exercise ,the Morris maze test was conducted for evaluating the cognitive function in each group .The rats were finally killed for detecting the ChAT activity and AchE activity of hippocampus .Results In the positioning navigation training ,the latency period of the sham operation group was significantly short than that of the exercise group and the model group ,but the latency period of the exercise group was obviously short than that of rats in the model group (P<0 .05);in the spatial exploration test ,the rats in the sham operation group had more frequency of crossing platform than the other two groups ,the exercise group had more frequency of crossing platform in platform quadrant than the model group (P<0 .05);the exercise training could increase the ChAT activity and lower the AchE activity of hippocampus .Conclusion The exercise training can improve the function of hippocampal cholinergic system in SHR/SP and then increase the cognitive ability .

Objective To detect the expression of the tryptase in the plasma,and study the meaning in brain traumatic patients.Methods There were two groups:the brain traumatic group(40 patients)and the control group (20 health people).The content of plasma tryptase was determined by fluorescence enzyme immunoassay..Results The level of plasma tryptase had no statistical significance in control group(2.97 ±1.05)μg/L compared with the brain traumatic group(3.03 ±1.39)μg/L,however there had statistical significance comparing with sever brain traumatic patients(3.84 ±0.52μg/L)(t =3.32,P <0.05).4 cases of death in patients with severe head injury group content of tryptase (5.85 ±1.05)μg/L,which was significantly higher than the group of 16 cases of injury in severe head injury after 2 months still alive with the content of serum tryptase (2.49 ±0.52)μg/L,the difference was statistically significant (t =8.13,P <0.01).Conclusion The plasma tryptase level in sever brain traumatic patients increased significantly,and might be of importance for treatment strategies and prognosis.

Objective To discuss the diagnosis and treatment of inflammatory granuloma in central nervous system(CNS)to provide reference for clinic.Methods Retrospective data included 8 patients with CNS inflammatory granuloma in Department of Neurosurgery,Shanxi People's Hospital,2012 -2015.We analyzed the imaging features, postoperative symptoms,blood and cerebrospinal fluid changes and prognosis.Results 8 cases all received surgical treatment.All the symptoms were improved,and the CT showed that the lesions were disappeared.All the patients had recovered to normal life and work.Conclusion The diagnosis of CNS inflammatory granuloma is difficult.Clinical manifestations are lack of specificity.The blood and cerebrospinal fluid laboratory examination have no abnormal changes.CT and MRI are the main diagnostic methods.Postoperative pathology is the gold standard for diagnosis.The large lesion,frequent episodes of epilepsy,severe neurological deficits and possibility of brain tumor all should be treated by surgery.

Objective To establish a Goto-Kakizaki ( GK) rat model of duodenal-jejunal bypass( DJB) and ob-serve the changes in insulin-resistance after surgery, and to explore the mechanism of DJB surgery in treatment of type 2 di-abetes mellitus.Methods Male Goto-kakizaki diabetic rats(GK,n=36)were used as experiment group and 18 healthy male Wistar rats as blank group.GK rats were randomly divided into two groups: diabetic control group and DJB surgery group ( n=18) .Euglycemic-hyperinsulinemic clamp technique was performed in 6 rats randomly taken from each group at third week, sixth week and ninth week after surgery, respectively.The expression levels of Gck, G6P, PEPCK mRNA in the liver and GLUT4 content on skeletal muscle cell plasma membrance were detected one week after the clamp test. Results In the DJB surgery group at the end of third week and sixth week after surgery, the levels of glucose infusion rates and the expression levels of Gck, G6P, PEPCK mRNA in the liver showed no statistically significant difference as com-pared with the diabetic control group (P>0.05).In the DJB surgery group at the end of 9th week after surgery, the glu-cose infusion rate and expression level of Gck mRNA in the liver were significantly higher, and the expression of G6P and PEPCK mRNA was significantly lower than those in the diabetic control group ( P<0.05 for all) .At the three time points (3rd week, 6th week and 9th week after surgery), there was no significant difference in the GLUT4 content on skeletal muscle cell plasma membrane between the diabetic control group and DJB surgery group ( P>0.05 for all) .Conclusions Our results indicate that the mechanism of DJB surgery improving blood glucose level may be closely related to the amel-ioration of insulin-resistance in the liver, thereby augmenting glucose uptake and inhibiting gluconeogenesis in liver through the regulation of glucose metabolism-related enzymes.There is no significant improvement in insulin-resistance in the skele-tal muscles during the experiment period.This result implies that the effect of DJB surgery on type 2 diabetes is related to the duration of therapy.
