Objective: To prepare voriconazole long-circulation liposomes and evaluate the characteristics of pharmacokinetics in rats.Methods: Voriconazole long-circulation liposomes were prepared by a thin film dispersion extrusion method.The drug release of voriconazole from the long-circulation liposomes was investigated in phosphate buffer solution (PBS) and in rat plasma.The physicochemical properties of the long-circulation liposomes before and after the freeze-drying were studied, such as the particle diameter and the particle shape.The concentration of voriconazole in plasma was determined after tail-vein injection of the long-circulation liposomes in rats.Results: The mean particle size of voriconazole long-circulation liposomes was (192.1±49.3)nm with homogeneous small spherical morphology as seen under a transmission electron microscope.Voriconazole was released in a sustained manner in PBS while much faster in plasma from the long-circulation liposomes.The t1/2 and AUC0-t of the long-circulation liposomes was respectively 2.17 and 2.31 times higher than that of voriconazole injection.Conclusion: Long-circulation liposomes prolong the circulation time and increase the bioavailability of voriconazole.

Objective To investigate the treatment effect of sertraline combined with psychological intervention on depression, and evaluate its application value. Methods 162 cases of patients with depression in our hospital from February 2014 to March 2017 as the research object, by double blind were randomly divided into reference group and observation group,with 81 cases in each group. All the patients were treated with sertraline treatment, on this basis,the reference group was given routine nursing intervention, the observation group added psychological intervention in nursing care on the basis of the reference group.The clinical treatment of the two groups was observed. Results The HAMD scores of the two groups were significantly improved after intervention, and the effect of the observation group was better than that of the reference group (P<0.05). The total follow-up rate and the total effective rate of the treatment group were significantly higher than the reference group, the difference was statistically significant(P<0.05). Conclusion Sertraline tablet combined with psychological intervention is effective in the treatment of depression, and can effectively improve the treatment compliance of patients, and then enhance the clinical treatment effect, the value is remarkable.

Peritoneal macrophages were obtained from normal LACA mice and the phagocy-tosis of neutral red was measured after 24 hr.incubation with different opiate peptidesand ACTH.?-endorphin(10~-(10)-10~_6M)and dynorphin A(10~_(10)-1(10~_6M)were found tostimulate the phagocytosis and these increases in phagocytosis could be reversed byopiate receptor blocker,naltrexone(10~_5M).[D-Ala~2,D-Leu~5]-enkephalin(10~_(12)-10~_6M),however,had no effect on the phagocytosis.ACTH(10~_(10)-10~_6M)was fo-und to have suppressive effect on the phagocytosis.These results suggest that diffe-rent opiate peptides may cause different effects on phagocytosis of macrophages andthe increase in phagocytosis induced by ?-endorphin and dynorphin appears to be me-diated by opiate receptors on peritoneal macrophages.

132 medical students were selected and divided into two sections.One was the experimental group using scene play teaching method,the other was the contrast group using traditional teaching methods.And a contrast research between them was conducted.The result showed that the experimental group's grades of theory and practice were more excellent than the contrast group,which shows that the scene play teaching method excels the traditional teaching method and is worth further promoting.

Objective To assess the effect of different clinical interventions for gastric tube in patients undergoing gastrointestinal operations for measuring the risk of postoperative complications and recovery of gastrointestinal tract. Methods A total of 148 patients undergoing gastrointestinal operations were recruited and divided into Group A, B, C and D, with 37 cases in each group. All patients underwent perioperative management based on the concept of rapid rehabilitation surgery. Group A were not indwelled with gastric tube with routine method. Group B were indwelled with gastric tube with routine method and got nasogastric extubation 5 min before tracheal extubation. Group C were indwelled gastric tube with routine method and got nasogastric extubation 6 h after fully conscious of anesthesia. Group D indwell gastric tube with routine method and got nasogastric extubation 12 h after fully conscious of anesthesia. The parameters including time of the first passing of flatus, defecation and resuming peristaltic sound after operation between the groups were compared. Vasoactive Intestinal Peptide (VIP), Motilin (MTL) and Glucagon (GLU)before the operation, and at the 1st, 3rd and 7th day after operation were measured by radioimmunoassay. Results Time of the first passing of flatus, defecation and resuming peristaltic sound after operation showed a rising trend from Group A to Group D. The difference in time of the first passing of flatus was not significant (P>0.05), time of defecation and resuming peristaltic sound after operation in Group A were significantly shorter (P<0.05). There were no statistical differences in VIP, MTL, GLU among the groups before the operation and at the 1st day after operation (P>0.05). VIP in Group A at the 3rd day after operation was significantly lower than those in other 3 groups , with the increasing of time for indwelling tubes. VIP showed a rising trend. MTL showed a decreasing trend with the increasing of time for indwelling tubes at 3rd and 7th day after operation. GLU in Group A was the highest (P<0.05) . GLU showed a rising trend with the increasing of time for indwelling tubes at 3rd and 7th day after operation. GLU in Group A was the lowest (P<0.05) . The pharyngeal discomforts were least in Group A (P<0.05) .Pulmonary infection rate showed a rising trend with the increasing of time for indwelling tubes, but the difference was not significant (P>0.05). Nausea and vomiting, anastomotic fistula, intestinal obstruction, abdominal distension in 4 groups showed no significant differences (P>0.05). Conclusion Avoidance of gastric tube in gastrointestinal operations can benefit the postoperative recovery of gastrointestinal tract , reduce pharyngeal discomforts and pulmonary infections. For patients with indwelled gastric tube, the time for indwelling tubes should be shorten, in order to speed up the recovery process and improve the safety of the patients.

Obesity and vitamin D deficiency have become two public health problems in children.In the past few decades,there has been increasing concern that low circulating levels of serum 25 (OH) D are associated with obesity and other metabolic diseases linked.However,the causal relationship between vitamin D deficiency and obesity is still unclear.There is currently insufficient evidence of beneficial effect to recommend vitamin D supplementation as a means of improving body weight,BMI or fat mass.Obesity probably leads to lower 25 (OH) D starus,while vitamin D and VDR are considered to have the ability to regulate energy balance through acting on adipogenesis,adipocyte apoptosis,lipogenesis and lipolysis,feeding behavior,and energy expenditure.

Objective To evaluate the efficacy of Huayu-Zhentong capsule combined with traditional manipulation in patients with inflammatory cytokines after operation of lumbar intervertebral disc herniation.Methods A total of 80 patients with orthopedic inpatients were enrolled and divided into two group by random number table method:a treatment group (40 patients) and a control group (40 patients).On this basis,the control group was added to loxoprofen sodium dispersible tablets,the treatment group was added to Huayu-Zhentong capsule.2 groups were continuous treated for 2 courses.Flow cytometry was used to detect the level of IL-8 and IL-6 before and after treatment,and the patients were evaluated by VAS.The clinical efficacy was evaluated by Oswestry ODI.Results After treatment,the VAS score (2.22 ± 0.31 vs.3.54 ± 0.67,t=11.309) and ODI (10.51 ± 3.22 vs.15.54 ± 6.21,t=4.548) of the treatment group were decreased than the control group (both P＜0.01).Lymphocyte IL-6(0.58％ ± 0.20％ vs.0.84％ ± 0.32％,t=4.358),IL-8(0.41％ ± 0.11％ vs.0.61％ ± 0.20％,t=5.542),mononuclear cells IL-6(25.31％ ± 4.26％ vs.29.19％ ± 5.32％,t=3.604),IL-8(17.80％ ± 2.81％ vs.3.31％ ± 3.77％,t=7.411) of the treatment group were lower than the control group (all P＜0.01).The total effective rate (100％ vs.75.0％) of the treatment group was better than the control group (x2=9.257,P=0.002).Conclusions Huayu-Zhentong capsule combinated with traditional manipulation can reduce inflammatory cytokines IL-6 and IL-8 levels in patients with LIDH.Its curative effect is better than traditional manipulation with loxoprofen sodium dispersible tablets.
