Objective To detect the effect of Rhubarb retention enema on patients with acute pancreatitis(AP).MethodsA total of 84 AP patients were enrolled in this study. Patients were divided into the control group(n=42) and Rhubarb enema observation group(n=42). Control group was treated with fasting, continuous gastrointestinal decompression, correcting water electrolyte and acid-base imbalance, with the oral administration of octreotide and gabexatemesilate to inhibit pancreatic secretion and enzyme activity. On the basis of the control group, the observation group was treated with rhubarb retention enema. IL-17, IL-10, and IL-6 expression was detected by ELISA analysis. The clinical effect was compared.Results The clinical effect rate (85.7%vs.71.4%,χ2=2.366,P=0.043) in observation group was significantly higher than that in control group. After treatment of 7 days, IL-17 (13.53 ± 3.16 ng/mlvs. 20.63 ± 4.83 ng/ml,t=2.416) and IL-6 (22.82 ± 4.56 ng/mlvs. 31.59 ± 6.63 ng/ml,t=2.421) expression was significantly lower and IL-10 (16.32 ± 4.15 ng/mlvs. 12.17 ± 3.22 ng/ml,t=2.326) expression was significantly higher in observation group than those in control group(P<0.05). The reduction of blood amylase (125.69 ± 32.47 U/Lvs. 259.26 ± 51.44 U/L,t=7.451) and urine amylase (204.73 ± 43.83 U/Lvs. 334.25 ± 60.18 U/L,t=7.323) in the observation group was significantly higher than those in the control group(P<0.01). Abdominal pain and abdominal distension recovery time (4.24 ±1.06 dvs. 3.02 ± 0.62 d,t=2.521), exhaust gas and defecation recovery time (5.42 ± 1.25 dvs. 3.26 ± 0.73 d,t=5.124), temperature recovery time (5.63 ± 1.46 dvs. 4.58 ± 0.92 d,t=2.418), and hospitalization time (18.65 ± 4.16 dvs. 13.78 ± 3.15 d,t=2.386) were higher in control group than those in observation group (P<0.05 orP<0.01). Conclusion Rhubarb enema can regulate the IL-17/ IL-10, and inhibit the inflammatory reaction.

Retinocytoma is a benign tumor arising from the retina.Since it was first described by Gallie in 1982,retinocytoma has been progressively recognized.More and more clinical and pathological studies indicate that retinocytoma may be a early stage or a type of retinoblastoma.Retinocytoma is difficult to be found because of lack clinical signs.Therefore,it is very important for us to follow-up and screen the families of RB patient in order to intervene with the course of disease as early as possible for preventing and arresting the malignization of retinocytoma toward RB.The name alteration,clinical manifestations,histopathological features,molecular mechanism and heredity characteristics were reviewed.

Objective To explore the clinical effect of local prophylactic application of methotrexate(MTX) in laparoscopic linear salpingostomy. Methods The data of 102 women with confirmed unruptured tubal pregnancy and desire to conceive were collected.They were divided into two groups: the study group(local application of MTX in the operation,n=51) and the control group(without application of MTX,n=51).The demographic data,the incidence of persistent ectopic pregnancy(PEP)postoperation,and the hysterosalpingography(HSG) 3 months(postoperation) were analysed,and the side effects of the study group were observed. Results There was 1 case of PEP in the study group and 9 cases in the control group(2.0% vs 17.6%,P0.05).There were no obvious side effects such as nausea,vomit and dental ulcer in the study group. Conclusion Patients who were treated with local MTX injection during the laparoscopic linear salpingostomy present less incidence of PEP with no obvious side effects.

With the standard of living improved, people had less and less interests in exercise, adiposity has being a problem that people have to be up against all over the world. Exercise can step up energy expenditure, decrease fat accumulation, minish the volume of fat cell, and is one of widely used, effective, safe, economical measures of anti-adiposity. The adaptable change of neuroendocrine system in exercise quicken up fat to burn more. Leptine is an important signal of measuring fat content of body. The relationship between adiposity and leptin, and the effect of exercise on leptin was reviewed in this paper.

Objective To investigate the situation of the activities of daily living(ADL)for elderly people in Changsha,and analyze the influencing factors. Methods Questionnaire survey on ADL was held in 2239 elderly people(ranging from 60 to 91 years old),and the influencing factors including age,sex,family structure,marital status,education level,occupation,common chronic diseases and medical care consciousness were analyzed. Results Going to the toilet irregularly hadthe highest injury rate in physical self-maintenance viability(18.2%).But in instrumental ADL,the highest injury rate occurred while shopping(26.3%).Advanced age,living alone,losing spouse,sickness and the lack of medical care awareness were the major factors that influenced the ADL of the elderly people. Conclusions The ADL is an important indicator which reflects the health condition of elderly people.Advanced age,living alone,losing spouse,having many chronic diseases and lacking in medical care awareness are risk factors.

Baicalein (BAI) is an effective bactericide. The antibacterial activity and mechanism experiments were carried out by determining conductivity and content of macromolecules of membrane penetrability, the oxidative respiratory metabolism and protein synthesis changes and the inhibition of DNA topoisomerase activities. Electrical conductivity and the number of large molecules of BAI increased 2.48% and 1.8%, respectively, than that of the control. However, the membrane integrity did not destroyed by BAI directly. With BAI treatment, inhibition rates of activities for SDH and MDH were 56.2% and 57.4%, respectively, demonstrating that BAI could inhibit cell respiratory. After treated with BAI for 20 h, the total soluble content of proteins decreased by 42.83%. Moreover, the activities of DNA topoisomerase I and II were inhibited completely by 0.2 mmol x L(-1) BAI. These results indicated that BAI had obvious antibacterial activity on Staphylococcus aureus. The mechanism is that it could affect bacterial membrane penetrability, inhibit protein synthesis and influence SDH, MDH and DNA topoisomerase I and II activities to exert its antibacterial functions.

Objective To evaluate the clinical diagnostic value of coronary artery calcification score(CACS)of multi-slice spiral computed tomography(MSCT)combined with carotid intima-media thickness(IMT)measure in elderly patients with coronary artery disease(CAD). Methods　CACS of MSCT,carotid IMT measure,and coronary angiography were performed in 68 patients,including 36 cases with CAD(CAD group)diagnosed by coronary angiography and 32 cases(control group)with coronary arterial stenosis(＜50% stenosis).CACS and carotid IMT were compared between two groups. Results　The coronary artery calcification score was significantly increased in CAD group compared with the control group[(349.5±86.3)vs.(74.7±25.2),t=13.670,P＜0.01],and it was increased with the severity of coronary arterial stenosis.The carotid intima-media thickness in CAD group showed significant difference with that in control group[(1.11±0.05)mm vs(0.69±0.13)mm,t=13.587,P＜0.01].In CAD group,CACS exhibited a significant positive correlation with carotid IMT(r=0.950,P＜0.01).The positive rates of CACS and carotid IMT were both 77.8% (28 cases)in CAD group and both 12.5%(4 cases)in control group,which showed significant difference between two groups(X2=28.976,P＜0.01). Conclusions　CACS of MSCT combined with carotid IMT have high sensitivity and specificity in evaluating coronary arteriaI stenosis.It can be used as a non-invasive examination to diagnose CAD in the elderly.

Objective To investigate the effects of angiotensin-converting enzyme inhibitor (ACEI) lisinopril on experimental diabetic peripheral neuropathy (DPN) in the earlier stage and its mechanism. Methods Diabetes was induced by streptozotosin (STZ) in rats. After 8 weeks of treatment, the effects of lisinopril on function and structure of peripheral nerves were observed; superoxide dismutase, malondialdehyde, Na+K+-ATPase activity in sciatic nerve and NO, NO synthase levels in plasma were determined, and capillary density of sciatic nerve were also assessed. Results With lisinopril, nerve structure and function was improved, oxidative stress state was ameliorated, and NO level, Na+K+-ATPase activity and capillary density of endoneurium were increased (all P<0.05). Conclusion ACEIs are effective in DPN. The possible mechanisms may be related to the amelioration of ischemic state and related metabolic disorders of the nerves.
