Objective To compare the efficacy and cost of surgical clipping and endovascular embolization in the treatment of anterior and posterior communicating artery aneurysm and to conduct cost-effectiveness analysis. Methods The data of treatment outcomes and costs in patients with anterior or posterior communicating artery aneurysms admitted to Huashan hospital from 2002 to 2006 were analyzed using a retrospective cohort study. Results A total of 302 patients were included in the study. They were divided into surgical clipping group (n = 150; 65 males, age [48. 11 ±9. 94] years), interventional treatment group (n = 152;75 males, age [52. 56 ± 11. 09] year). The age of the former was lower than that of the latter (t = -3. 670, P =0. 000). There was no significant difference in preoperative clinical conditions (such as location of aneurysms and Hunt-Hess grade) between the two groups. The good outcome rate in the interventional treatment group was significantly higher than that in the surgical clipping group (84. 87% vs. 74. 67%, χ2 = 4. 875, P = 0. 027). There was no significant difference in hospital mortality (5. 33% vs. 3. 94%,χ2 =0. 328, P =0. 567) and complication rate (26.67% vs. 19. 74% , χ2 =2.036, P =0.154) between the surgical clipping group and the interventional treatment group, but the intraoperative aneurysm rupture (10. 67% vs. 3. 95%, χ2 =5.047, P =0.028) and the incidence of postoperative intracranial infection (6/144 vs. 0/152, χ2 = 6.203, P =0.014) in the surgical clipping group were higher than those in the interventional treatment group. The length of hospital stay in the interventional treatment group was significantly shorter than that in the surgical clipping group ([10. 0 ± 7. 0] dvs. [23.0 ± 11. 0] d, Z = -10. 35, P <0.001). The median cost of treatment was 95 327.63 %,yuan in the interventional treatment group, and the interquartile range (IQR) was 26 312. 98 yuan; it was significantly higher than the surgical clipping group (median 30 072. 01 yuan, IQR 11 178. 54 yuan) (Z = -14.449, P<0.001). Compared with the surgical clipping group, while the mRS score improved in the interventional treatment group 0. 10, the cost was about 66 438 yuan, so that the surgical clipping was more cost-effective. Conclusions The efficacy of the intervention treatment of anterior and posterior communicating artery aneurysms is better than that of the surgical clipping The mortality and total complication rate are almost the same with the surgical clipping Thehospital stay is shorter, but the cost of treatment is higher. From an economic point of view, the surgical clipping is more cost-effective.

Given the myriad of choices available on the market, selecting the appropriate wound dressing remains a challenge for most healthcare workers. It is important to exercise discretion and adopt a systematic approach in dressing selection following wound assessment, as this will directly impact on rates of wound healing, which in turns affects the patient’s quality of life and overall healthcare costs. This paper provides an overview of the common types of wound dressings in use currently and gives a brief synopsis of some of the latest advances in wound care technology and their applications in management of complex wounds. The consensus to date is for the use of hydrogels in the debridement stage, foams and low-adherence dressings in the granulation stage and hydrocolloids and low-adherence dressings for the epithelialization stage. Additional studies and research need to be undertaken to further evaluate the application of advanced wound technology in clinical practice.

Objective To explore the effect of community comprehensive rehabilitation on quality of life in patients with stroke sequelae under the family medical service mode. Methods From October, 2013 to October, 2014, 51 patients with stroke sequelae received compre-hensive rehabilitation intervention for three months, including rehabilitation training, rehabilitation guidance, health education and psycho-logical counseling. They were assessed with modified Barthel index (MBI), WHO-Disability Assessment Schedule (WHO-DASⅡ), Short Form 36 Health Survey Questionnaire (SF-36), Brain Injury Community Rehabilitation Outcome Scales (BICRO-39), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) before and after intervention. Results The scores of physical functionning, role physical, general health, mental health, social functioning and the total score in SF-36 increased after intervention (t>2.072, P<0.05). The scores of so-cial contact, locomotivity, self handling transaction ability and the total score in BICRO-39 decreased after intervention (t>2.434, P<0.05), as well as the scores of getting along with people, housework and society and participation in WHO-DAS II (t>2.507, P<0.05). Conclusion In the community health service, comprehensive rehabilitation guided by multidisciplinary rehabilitation team can facilitate to improve the quality of life in patients with stroke sequela.

OBJECTIVETo explore the intervention of Huayu Qutan Recipe (HQR) on liver SREBP-2 signal pathway of hyperlipidemia rats of Pi deficiency syndrome (PDS).
METHODSTotally 100 SPF grade SD rats were randomly divided into the blank control group, the hyperlipidemia group, the hyperlipidemia treatment group, the PDS hyperlipidemia group, and the PDS hyperlipidemia treatment group, 20 in each group. Common granular forage was fed to rats in the blank control group. High fat forage was fed to rats in the hyperlipidemia group and the hyperlipidemia treatment group. Rats in the PDS hyperlipidemia group and the PDS hyperlipidemia treatment group were treated with excessive labor and improper diet for modeling. They were administered refined lard by gastrogavage (3 mL each time, twice per day) and fed with high fat forage on the odd days, and fed with wild cabbage freely on even days. The modeling lasted for 30 days. Rats in the hyperlipidemia treatment group and PDS hyperlipidemia treatment group were administered with Huayu Qutan Recipe (20 mL/kg) by gastrogavage, once a day, for 30 successive days. Levels of serum cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), and serum amylase (AMY) were detected by automatic biochemical analyzer. D-xylose excretion rate was determined using phloroglucinol method. Morphological changes of liver and the lipid deposition in liver were observed using HE stain and oil red O stain respectively, mRNA and protein expression levels of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR), cholesterol 7α-hydroxylase 1 (CYP7A1), LDL-R, and sterol regulatory element binding protein-2 (SREBP-2) were detected using real time RT-PCR and Western blotting.
RESULTSCompared with the blank control group, serum levels of TC (1.84 ± 0.19 mmol/L, 2.23 ± 0.43 mmol/L) and LDL-C (0.99 ± 0.24 mmol/L, 1.13 ± 0.56 mmol/L) were higher in the hyperlipidemia group and the PDS hyperlipidemia group, serum levels of HDL-C (0.41 ± 0.66 mmol/L, 0.41 ± 0.11 mmol/L) and AMY activities (351 ± 45 mmol/L, 153 ± 30 mmol/L) were lower, and urinary D-xylose excretion rates were lower (26.9 ± 2.1 ng/mL, 15.0 ± 1.7 ng/mL) (all P < 0.05). Lipid deposition occurred in liver cells. Much fat vacuoles occurred in the cytoplasm. Expression levels of HMGCR, CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver significantly decreased (P < 0.01). Compared with the hyperlipidemia group, serum levels of TC and LDL-C significantly increased (P < 0. 05), AMY activities and urinary D-xylose excre- tion rates significantly decreased in the PDS hyperlipidemia group (P < 0.01). A large amount of lipid deposition occurred in liver. The atrophy of liver cells was obviously seen. Expression levels of CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver were significantly lower (P < 0.01, P < 0.05). Serum levels of TC and LDL-C significantly decreased (P < 0.05), AMY activities and urinary D-xylose excretion rates significantly increased in the hyperlipidemia treatment group (P < 0.01). Expression levels of CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver were significantly increased (P < 0.01, P < 0.05). Compared with the PDS hyperlipidemia group, serum level of TC significantly decreased (P < 0.05), HDL-C levels, AMY activities and urinary D-xylose excretion rates significantly increased in the PDS hyperlipidemia treatment group (P < 0.01),expression levels of CYP7A1, LDL-R, and SREBP-2 mRNA and proteins in liver were significantly increased (P < 0.01). Similar changes occurred in the two treatment groups.
CONCLUSIONSPi deficiency exacerbates abnormal serum TC level and the lipid deposition in liver. These might be related to regulating expression levels of LDL-R, HMGCR, and CYP7A1 genes in the SREBP-2 signal pathway. HQR could regulate this pathway to intervene abnormal metabolism of TC.
