Objective To explore the effect of psychological intervention combined with drug multimodal therapy on orthopedic analgesia and its effect on stress response, and to provide reference for clinical application.Methods 88 cases treated with open reduction and internal fixation for lower limb fracture as the object of study were collected from March 2015 to March 2017 in Baoji traditional Chinese medicine hospital, which were received multi-mode drug treatment.According to whether to receive psychological intervention, 88cases were divided into the intervention group(45 cases) and the control group(43 cases).Postoperative pain was assessed by visual analogue scale(VAS) and simplified McGill questionnaire(SF-MPQ), the changes of plasma CRP and IL-6 levels were compared before and after operation.Results There was no significant difference in VAS score, SF-MPQ score, preoperative plasma CRP and IL-6 levels between the two groups.One and 24 hour after operation, VAS score and SF-MPQ score were higher than those at admission(P<0.05).The VAS score and SF-MPQ score in the intervention group were lower than those in the control group at different time points(P<0.05).One and 24 hour after operation, plasma CRP and IL-6 levels in the two groups were significantly higher than those before operation(P<0.05), the levels of plasma CRP and IL-6 in the intervention group were significantly lower than those in the control group(P<0.05).Conclusion Psychological intervention combined with multimodal drug therapy can effectively reduce the degree of postoperative pain and stress reaction, and is conducive to postoperative rehabilitation.

Objective: To prepare visualized iodized oil-5-fluorouracil loaded polylactic acid(PLA) micropheres for hepatic artery embolism treatment. Methods: Biocompatible and biodegradable material PLA was used as vector and iodized oil was used as positive contrast agent to prepare 5-fluorouracil loaded microspheres using double emulsion method. The preparation technology of the microspheres was developed through optimization of appearance, size distribution, drug loading, and encapsulation efficiency by orthogonal-designing method. Results: The prepared PLA microspheres were round in shape and had a homogenous diameter distribution. Scanning electron microscope (SEM) showed a pored surface, with an average diameter of 100 μm. The encapsulation efficiency and drug content of microspheres were (63.34%±0.54%) and (10.78%±0.14%), respectively. Conclusion: We have successfully prepared the visualized iodized oil-5-fluorouracil PLA microspheres, which can release 5-fluorouracil in a controlled manner.

Objective To investigate the effect of propofol and fentanyl on inflammatory response to tissue injury in children undergoing open heart surgery with CPB and the possible mechanism. Methods Twenty HYHA class Ⅱ - Ⅲ children with congenital heart disease, aged 10 month-12yr, undergoing elective open heart surgery were randomly divided into two groups: group F in which anesthesia was maintained with high dose fentanyl (50-80?g? kg-1 ) and group FP in which anesthesia was maintained with propofol infusion (20mg?kg-1?h-1 ) and intermittent iv boluses of fentanyl (

Objective To investigate effect of intravitreal injection of FK506 on the survival of human retinal pigment epithelial (RPE) cells heteroplastically transplanted into the subretinal space of rabbits. Methods The immortalized human RPE cells were genetically labeled by retrovirus vector carrying a green fluorescent protein (GFP). A total of 50 ?l RPE cells suspension with 4?10 3 cells/?l which expressed GFP were injected into the subretinal space of both eyes of 18 white rabbits and 10 gray rabbits. The left eyes of all of the rabbits were injected of 5 ?l FK506 (5 ?g/?l) intravitreally once a week during the first 5 weeks, then once every other week until the 20 th week and the right eyes were as the control. The histological sections of heteroplastic RPE cells were observed by epifluorescent microscope. Results GFP-expressing cells could be seen after 1 week, 2, 3, 4, 6, 10, 11, 14, 18, 20, 23, 24, 25, 26, 33, and 54 weeks in white rabbits and after 4, 5, 6, 7, 14, 18, 20, and 26 weeks in gray rabbits. The configuration and integrality of the RPE-GFP cells in the left eyes which had been intravitreally injected of FK506 1-14 weeks after transplantation were better than those in the right eyes without injection. After 18 weeks, the condition of heteroplastic cells with few difference in both eyes in 7 white and 3 gray rabbits were found. After 1-6 weeks, focal and disseminated lymphocytes around the choroidal small vessles of right eyes in 6 white and 3 gray rabbits could be seen while the infiltration of the lymphocytes in the left eyes was much reduced. Conclusion Intravitreal injection of a small amount of FK506 at the first 3 months after transplantation may significantly improve the survival of heteroplastic RPE cells in the subretinal space of rabbits.

Objective To investigate the expression of IL-10 and IL-6 in tissue and plasma of subtypes lymphoma and its significance. Methods Immunohistochemical technique and enzyme-linked immunosorbent assay (ELISA) were used to assess the expression of IL-10 and IL-6 in 97 cases paraffin tissue and plasma samples from different subtypes of lymphoma.Results Expression of IL-10 and IL-6 was positive in all lymphoma tissue samples, but there is no significant difference among different subtypes lymphoma (x2 =0.815, x2 =0.542, P ＞ 0.05). Tumor samples were found positive IL-10 and IL-6 expression in macrophages and vascular endothelial cells by immunohistochemistry respectively. Expression of IL-10 and IL-6 in plasma of lymphoma were higher than that in control respectively [(232.57±191.59) pg/ml vs (59.12±68.35) pg/ml,(80.70±89.68) pg/ml vs (45.68±33.66) pg/ml],with significant difference (t =6.968,t =2.896,P ＜0.05).IL-10 and IL-6 plasma levels increased with enhanced expression in lymphoma (x2 =0.815,x2 =0.542,P ＜ 0.05).Which was found to be correlated with each other (rs =0.394,P ＜ 0.05). Conclusion The expression of IL-10 and IL-6 had been found at various degrees in tissues and plasma of lymphoma.IL-10 and IL-6 in plasma of lymphoma were higher than that in controls. These results showed that IL-10 and IL-6 may cooperate in vivo with lymphoma cell proliferation and infiltrate. IL-6 and IL-10 maybe served as useful indicators for diagnosis of lymphoma.

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a common clinical disease that seriously threatens human health and life. Accurate location of the upper airway obstruction is the key to the diagnosis and treatment of OSAHS. Acoustic pharyngometry uses sound reflection to quickly assess the cross-sectional area and volume of the upper airway. Acoustic pharyngometry represents a simple, quick, non-invasive method for measuring upper airway dimensions which could predict sleep apnea risk. In this article we sought to introduce the application of acoustic pharyngometry in the diagnosis and treatment of OSAHS.

Objective To study arterial distribution of rectus abdominis musculocutaneous flap and to evaluate whether it can be divided into several units for reconstruction. Methods The arteries of the rectus abdominis musculocutaneous flap were studied on 60 sides of cadavers by dissection and angiography. Results The superior epigastric artery (SEA) and the inferior epigastric artery (IEA) continued in a longitudinal direction. Most of their branches took on a typical spiral configuration and communicated with each other within muscle above the level of umbilicus. Many perforating arteries penetrated through the anterior rectus sheath to get to the overlying skin, but the highest concentration of major perforators were in the paraumbilical area. The inferior epigastric artery was more significant than superior epigastric artery in supplying the skin of the musculocutaneous flap. Based on thefstudies of the vascular anatomy of muscles, we could classify arterial distribution into 3 types: type Ⅰ (SEA 26.5 %, IEA 34.6%) revealed a single main intramuscular artery: type Ⅱ (SEA 64.7 %, IEA 48.1%) had two major intramuscular branches; type Ⅲ (SEA 8.8%, IEA 17.3 %) revealed three intramuscular branches. Our anatomic studies showed that the superior and inferior epigastric artery bifurcated or divided into more than two main branches in the majority of cases (SEA 73.5%, IEA 65.4%). Conclusion The rectus abdominis musculocutaneous flap could often be divided into several regions for breast construction which is based on the distribution of each branch of the artery.
