Objective To investigate the effect of Osthole on memory function of sleep deprivation(SD) mice. Methods Forty-eight male mice were randomly divided into 4 groups;normal control group(NC group ), large platform control group(TC group),sleep deprivation group(M group)and Osthole group(Ost group). The model of SD in mice was estabished by using improved multi platform method. The ability of learning and memory was tested by using Morris water maze test and pathological changes of hippocampal neurons in mice were observed by HE staining. The serum,hippcampus malondialdehyde(MDA)contents and superoxide dismutase(SOD)activity, so as the hippocampus No content,were detected. Results Compared with NC group and TC group,the escape la-tency of M group increased significiantly and the number of crossing platform decreased significantly. There were in-creased levels hippocampus tissue,serum MDA level,hippocampal SOD activity and NO content. After supplemen-tation of Osthole,the escape latency significantly shortened in mice. The number of crossing platform was increased while the contents of MDA both in hippocampus and serum were decreased,and the SOD activity in hippocampus re-turned to normal. However,the level of NO in hippocampus was not decreased. Conclusion Osthole can protect the memory function of SD mice by reducing the the damage of hippocampal neurons through antioxidant stress.

Objective To explore clinical application value of Traditional Chinese Medicine nursing technology to decrease postoperative complication after breast cancer surgery.Methods Randomized controlled trial,large sample size,multicenter study design were adopted,and 200 patients who met inclusion criteria were randomly divided into the control group and the treatment group (100 cases in each group).The control group received routine nursing methods after breast cancer surgery.The treatment group received routine nursing methods as well as Traditional Chinese Medicine nursing intervention,such as auricular application pressure,acupoint sticking,meridian moxibustion.Data of arm circumference,Athens insomnia scale(AIS),symptom in affected arm were collected a week before and after surgery,and range of motion of shoulder joint was evaluated 3 months after surgery to compare postoperative subcutaneous effusion,skin flap necrosis,limb edema,sleep disorder and occurrence of shoulder joint dysfunction in two groups.Results The cases developed postoperative subcutaneous effusion,skin flap necrosis,limb edema were different in two groups,but the differences were not statistically significant(P＞0.05).There were significant differences between two groups in affected arm pain,swelling,skin tension,sleep,and shoulder joint dysfunction after 3 months(P＜0.05).Conclusion Traditional Chinese Medicine nursing technology can effectively decrease postoperative complication after breast cancer surgery.

Objective To study the therapeutic effect of anti-CD80 bivalent antibody on mouse lu-pus nephritis and to explore the possible molecular mechanism. Methods A mouse model of lupus nephritis was established through intraperitoneal injection of 0. 5 ml of pristine in female C57BL/6J mice. Appearance of urinary protein and significantly increased levels of peripheral antinuclear antibody ( ANA) and anti-doub-le-stranded DNA ( anti-dsDNA) antibody in the fourth month after injection indicated that the mouse model was established successfully. Then the mice were divided into two groups including anti-CD80 bivalent anti-body intervention group (injected with 200μg of anti-CD80 bivalent antibody at day 1, 3, 5, 8 and 15, fol-lowed by three times of injection with an interval of one month) and model group ( injected with the same protein using the same strategy). A normal control group was set up accordingly. Albustix test paper was used to monitor the dynamic changes in mouse urinary protein. Flow cytometry was used to analyze the acti-vation of immune-related cells in spleen. Levels of autoantibodies ( ANA and anti-dsDNA) and levels of IFN-γ and IL-4 in serum were detected by indirect immunofluorescence assay. Renal tissue samples were an-alyzed with hematoxylin and eosin ( HE) staining and immunocomplex ( IC) assay. Results Urinary pro-tein level of the anti-CD80 bivalent antibody intervention group was significantly lower than that of the model group (P<0. 05). Activated macrophages, dendritic cells, neutrophils and B cells in spleen tissues of the anti-CD80 bivalent antibody intervention group were significantly less than those of the model group ( P<0. 05), and the numbers of CD4+ and CD154+ T cells were significantly less than those of the model group (P<0. 05). Positive rates and titers of ANA and dsDNA in serum samples of the intervention group were lower than those of the model group (P<0. 05). Levels of IFN-γand IL-4 in serum samples of the interven-tion group were decreased as compared with those of the model group (P<0. 05). HE staining and immuno-fluorescence assay showed that glomerular inflammatory injury and necrosis were alleviated and kidney im-mune complex deposition was reduced after anti-CD80 bivalent antibody intervention. Conclusion Anti-CD80 bivalent antibody specifically binds to the CD80 molecule on antigen presenting cell surface, blocks the CD80/CD28 co-stimulatory signaling pathway and down-regulates the body′s immune response, which al-leviates and reverses the lupus-like nephritis-induced pathological damages in mice.

OBJECTIVE:To optimize the formulation of ferulic acid ligustrazine (FATM) solid lipid nanoparticles (FATM-SLN),and conduct the quality evaluation. METHODS:Emulsification ultrasonic method was used to prepare FATM-SLN. Using particle size and entrapment efficiency as indexes,amount of glyceryl monostearate,egg yolk lecithin (PC),poloxamer 188 (P188),and sodium stearate as factors,single factor test and orthogonal test were used to optimize the formulation;and verifica-tion test was conducted. The appearance morphology,distribution of particle size,Zeta potential,stability and in vitro release de-gree of prepared FATM-SLN were investigated. RESULTS:The optimal formulation was as follows as FATM of 10 mg,glyceryl monostearate of 300 mg,PC of 200 mg,P188 of 200 mg,sodium stearate of 10 mg,and purified water of 20 mL. The prepared FATM-SLN showed spherical solid particles,appearance morphology was round,distribution of particle size was 40-800 nm,parti-cle size was 106.23 nm,polydispersity index was 0.254,Zeta potential was -34.8 mV,entrapment efficiency was 73.32%,drug loading was 1.20%;the appearance had no obvious changes within 10 d in 4 ℃(RSD<2%). The drug-release in 0.5-1 h was the fastest,the cumulative release degree reached to 60.47%;it tended to be stable after 8 h,the cumulative release degree reached to 93.46%,and drugs were basically released completely. CONCLUSIONS:FATM-SLN formulation is successfully optimized,and the prepared FATM-SLN has small particle size,high entrapment efficiency and good stability.

Objective To investigate the impact of nurses in operation room of implementing the comprehensive nursing intervention on psychological status and complications for laparoscopic common bile duct exploration patients. Methods All patients were selected in our hospital from January 2013 to March 2014 undergoing laparoscopic common bile duct exploration, according to different nursing methods they were randomly divided into intervention group and control group, 40 cases in each group. Two groups of patients were given perioperative nursing by nurses in operation room, the control group received the routine nursing and random symptomatic care, intervention group focused on the implemen-tation of comprehensive nursing intervention in nursing care such as psychological intervention, complications of T line pipe and complication care. The SAS score of two groups of patients before and after psychological intervention, opera-tion time, amount of bleeding complications, postoperative exhaust time, hospitalization time and rate of complication of two groups in surgery were compared. Results The postoperative SAS score of intervention group and the control group decreased significantly than preoperative (P<0.05). And the SAS score of the patients in the intervention group was significantly lower than that of the control group (P<0.05). The intraoperative bleeding volume, postoperative exhaust time of the intervention group were improved significantly compared with the control group (P<0.05), the operation time, hospitalization time of intervention group was shorter than that of the control group, but there were no significant dif-ference (P>0.05). The biliary stricture did not occur in two groups. In the intervention group, one case of gallstone residue, one case of postoperative. The complication rate in the intervention group was 5.0%,was significantly lower than the control group’s 12.5%(P<0.05). Conclusion Nursing in operation room to laparoscopic choledocholithotomy in patients through the implementation of comprehensive nursing intervention is beneficial to reduce the patients psycho-logical anxiety, reduce the incidence of complications and improve the operative effects.

Objective Compare the effect of reducing patients′ pulmonary infection by different post-thoracotomy breathing intervention management modes. Methods A total of 88 sampled patients, who had done thoracotomy, were divided chronologically 44 each into control group (February to March 2013) and test group ( April to May 2013 ) . Regular respiratory intervention management were conducted on the control groups and refined respiratory intervention management were given to the test groups, compare the effect of two groups. Results The temperatures (36. 27 ± 0. 30)℃ of the patients from the test group at 6 pm in the 4th day after surgery were lower than ( 36. 78 ± 0. 36 )℃ of the control group; difference between the two groups were statistically significant (t=7. 35,P<0. 05). The white blood cell analysis (6. 07 ± 1. 43) × 109/L in the 4th after surgery of experimental group tend to be more normal than the white blood cell analysis (7. 61 ± 1. 94) × 109/L of the control group with statistical significance (t=4. 27,P<0. 05). There were all normal for chest X ray in the test group, but 4 cases with lung patchy infiltrate shadows in the control group with incidence rate 9. 09%. Conclusions Refined breathing intervention management can make the body temperature, white blood cell, neutrophils ratio of post-operative patients recover to normal range quick without lung auscultation wet rales, and prevent post-thoracotomy pulmonary infection.
