Objective To evaluate the effect of wound experts′ intervention on the primary caregivers′ behavior of caring patients with pressure ulcers. Methods According to the principle of convenience sampling, 200 cases of patients with out-hospital pressure ulcers were collected in the hospital emergency department between December 2013 and December 2015. Each 100 cases were randomly divided into the intervention group and the control group according to odd even packet. Primary family caregivers in the intervention group were implemented the additional behavioral intervention by professional wound experts on the basis of the conventional education, while the control group only with conventional education. Primary caregivers′behavior score in the intervention group were compared in 1 month and 2 months. And the differences of recovery rate and incidence of pressure ulcers were compared between intervention group and control group. Results The recovery rate of pressure ulcers in intervention group was 59% (59/100) ,which was significantly higher than 32% (32/100) of the control group (χ2=14.690, P=0.000), and the incidence of pressure ulcers rate was 24% (24/100) in intervention group which was significantly lower than 39%(39/100) in the control group (χ2=5.214,P=0.022). Primary caregivers′behavior scores in the intervention group were (48.27±6.12) points after 1 month and (46.18± 4.44) points after 2 months, while those in the control group were (44.15 ± 4.33) points and (43.33 ± 5.67) points, respectively, and the difference of behavior scores in different time-points were statistically significant (F=18.93, P < 0.01). Moreover, the difference of behavior scores was also statistically significant between intervention group and control group (F=5.512, P < 0.05). Conclusions Wound experts′ intervention on home primary caregivers can effectively help improve caregivers′ behavior, promote the healing of pressure ulcers, and reduce the occurrence of complications.

Effects of antineoplastic agents on endocrine system are common, but it is difficult to identify since clinical complaints are subtle, and even more difficult to relate a particular chemotherapeutic regimen to the induced endocrine disturb. This review was organized according to the pattern of endocrine system diseases induced by antineoplastic agents, such as disorders of glucose metabolism, free water clearance, mineral metabolism, lipid metabolism and GH secretion and growth, metabolic bone diseases, adrenal dysfunction, thyroid disorders and reproductive dysfunction. Early detection and treatment of endocrine deficiency may have a significant impact on the quality and duration of life in a cancer survivor.

Objective Investigation of the clearance rate of RBC in cerebral spinal fluid(CSF)after lumber subarachnoid space continuous drainage following subarachnoid hemorrhage(SAH)and the relationship with cerebral vasospasm(CVS) were carried out. Methods An experimental SAH was achieved in dogs by twice injecting fresh autologous arterial blood into cisterna magna of each animal.RBC counts in CSF were measured in the drainage group, puncture group and control group respectively.The degrees of CVS were analyzed through cerebral angiography(%reduction of basilar artery diameter,%RBAD). Results Comparing with puncture group and control group, the drainage group showed a significantly higher clearance rate of RBC with lesser occurrance and degree of CVS. Conclusions RBC and its degeneratives in CSF may be involed in the process of CVS following experimental SAH. Continuous lumber subarachnoid space drainage may prevent CVS.

Objective To explore our clinical experience on treatment of intracranial and extracranial arterial stenosis using multiple stents placement. Methods 17 stents were deployed into 12 arteries in 8 patients with intracranial and extracranial arterial stenosis. We utilized self expanding stents in extracranial carotid arteries and balloon expanding stents for intracranial arteries or vertebral arteries. Results All procedures were performed successfully and all stenoses were dilated and improved. Short term follow up angiogram revealed only one vessel occlusion and no significant restenoses in other stented vessels together with no recurence of clinical symptoms. Conclusions Multiple stents placement is a valid alternative for the treatment of intracranial and extracranial arterial stenoses.

Objective To study formulation and characteristics of self-microemulsifying drug delivery system for breviscapine(BRV-SMEDDS).Methods The optimum formulations of BRV-SMEDDS were screened by solubility tests,formula compatibility,and pseudo-ternary phase diagrams.And the physicochemical characters,dissolution in vitro and in situ rat's intestine absorption of BRV-SMEDDS were also observed.Results The optimum formulation of SMEDDS was composed of Maisine 35-1-Cremophor RH40-PEG400-TEA=25∶40∶35∶7.The particle diameter was 88.6 nm.The percent of accumulated dissolution of BRV in SMEDDS in vitro was up to 97.8% at 1h,which was 8.0 times as much as that of BRV powder,and 5.1 times as BRV tablets.In the tests of in situ rat's intestine absorption,the permeability coefficient of BRV-SMEDDS was increased by 3.4 times as much as BRV powder,and 3.3 times as BRV tablets.Conclusion The dissolution and absorption of BRV is improved by formulation of SMEDDS.It could provide reference for the new dosage form of BRV.

ObjectiveTo study the effect of platelet aggregation rate (PAR) level on the prognosis of percutaneous transluminal coronary angioplasty (PCI).MethodsFour hundred and one patients who performed PCI were divided into 4 groups:group 1 (PAR≤30％,103 cases),group 2 (PAR 31％ - 40％,102 cases),group 3 (PAR 41％ - 49％,103 cases ) and group 4 (PAR ＞ 49％,93 cases ).All the patients were followed up.The survival analysis was performed in 4 groups.ResultsThe data of survival table were tested by 3 methods among 4 groups:statistic was 0.612,degree of freedom was 3,P =0.894 in Log-rank (Mantel-Cox) test,statistic was 0.567,degree 9f freedom was 3,P =0.904 in Wilcoxon test and statistic was 0.586,P =0.900 in Tarone-Ware test.There was no significant difference among them.The mean follow-up duration was 2.2 years,and there was no significant difference in survival function among 4 groups (P ＞0.05).ConclusionPreoperative and postoperative measurement of PAR levels may not improve the prognosis.

Objective　To investigate the effect of ipratropi um bromide and atropine on airway mucin hypersecretion in the chronic bronchiti s model of rats. Methods　The model was established by intratrac heal instillation of small dose of lipopolysaccaride (200 μg) ipratropium bromi de and atropine were administrated 3-21 d after the model was established. Patho logical changes, mucin in bronchoalveolar lavage fluid (BALF) and tracheal ring culture medium were examined before and after the adnsinistration of iprat ropium bromide and atropine. Results　Characteristic pathologica l manifestions of chronic brochitis were found after instillation of LPS. Sig nificant decrease in the number of tracheal epithelia goblet cells, secretion of mucin were observed in ipratropium bromide and atropine treated rats. The eff ect of inhibiting the secretion of mucin of ipratropium bromide was higher than atropine. Conclusion　It suggests that muscarinic acetylcholine receptor plays an important role in airway mucin hypersecretion in chronic bro nchitis model of rat. Ipratropium bromide exhibit a stronger inhibition effect on mucin hypersecretion than atropine, moreover no inhibition effect on mucocil iary clearance which was observed in atropine.

Objective To observe the effects of progesterone on the mRNA and protein expressions of nerve growth factor(NGF) and brain-derived neurotrophic factor(BDNF) in the focal cerebral ischemia-reperfused rats,and to explore its mechanism of brain protection. Methods Totally 96 healthy male SD rats were randomly divided into sham surgery group,ischemic reperfusion group,vehicle-treated group and progesterone-treated group (n=24 for each).The model of focal brain ischemia-reperfusion injury was induced by middle cerebral artery occlusion (MCAO).After 2 h temporary MCAO,rats were subjected to reperfusion for 3 h,6 h,12 h and 24 h,respectively.The mRNA and protein expressions of NGF and BDNF were analyzed by real time-PCR and Western blot,respectively. Results In the injured cortex,the mRNA and protein expressions of NGF and BDNF in ischemic reperfusion group came to the peak at 6 h after reperfusion,and then gradually declined to the level of sham operation group at 24 h after reperfusion.In progesterone treatment group,BDNF and NGF mRNA and protein expressions reach the peak at 12 h after reperfusion,and were still higher at 24 h after reperfusion than in ischemic reperfusion group(P＜0.05). Conclusions Progesterone plays a protective role in focal cerebral ischemia-reperfusion by increasing the expressions of BDNF and NGF in rats.
