Objective To investigate the effects of comprehensive pain management on pains and recovery of knee function of patients who hadundergone total knee arthroplasty(TKA).Methods A total of 50 patients who had undergone single-knee TKA surgery were selected and divided into 2 groups of 25 patients each:the study group and the control group.The control group was given patient-controlled epidural analgesia while the study group was given comprehensive pain management.The two groups were compared in terms of score on pain within 7 days after operation,knee joint activity and the incidence of adverse reaction within 10 days after operation(the 1st,3rd,7th,10th day).Results Within 7 days,the scores on pain in the study were significantly lower than those in the control group(P<0.05).The scores on the knee joint activity in the study group on the 1st,3rd,7th,10th day were significantly higher than those in the control group(P<0.05)and the incidences of adverse reaction were significantly lower as well (P<0.05).Conclusion Comprehensive pain management is effective for post-surgery pain control and the hastened TKA patients, and the improved quality of life.

BACKGROUND:Inflammation plays an important role in vessel proliferation after balloon injury.Reducing inflammatory reaction may lighten the ocurrence and development of the restenosis after angioplasty.Studies have demonstrated that PPAR? excitomotor has inhibitory effects on inflammation development.OBJECTIVE:To observe the changes in inflammatory factors after carotid artery balloon injury in rats and the intervention of PPAR? excitomotor rosiglitazone.DESIGN,TIME AND SETTING:The randomized,controlled animal experiment was performed at the Central Laboratory of Shenzhen People's Hospital from January to June 2009.MATERIALS:Male SPF SD rats weighing about 350 g were selected to generate models of carotid balloon injury.METHODS:SD rats were equally and randomly divided into 3 groups:the control group,the balloon injury group and the rosiglitazone group.The left common carotid arteries were injured by balloon in the balloon injury group and the rosiglitazone group.The control group received sham operation.The rosiglitazone group was administered rosiglitazone daily by gavage,which began 4 days before operation and continued until harvesting.Accordingly,the control group and the balloon injury group were administered normal saline daily by gavage.MAIN OUTCOME MEASURES:All rats were executed under anesthesia at 14 days after operation,respectively to harvest left common carotid artery samples.The vessels were stained by hematoxylin-eosin,and Neointimal area(NIA) and media area(MA) as well as NIA/MA were calculated.Real time RT-PCR and Western Blot method were used to assay the expression of interleukin(IL)-6,IL-10,IL-17A mRNA and the distribution of nuclear factor(NF)-?B protein.RESULTS:Of the 36 rats,5 were excluded due to failed modeling or death,and 31 rats were included in final analysis.①The expression levels of IL-6 and IL-17A mRNA in the rosiglitazone group were significantly lower than the balloon injury group,but higher than the control group(P

Objective To investigate the effect of phenylhexyle isothiocyanate (PHI) on demethylation and activation of transcription gene p15 in acute leukemia cell line Molt-4. Methods DNA sequencing and modified methylation specific PCR (MSP) were used to screen p15-M and p15-U mRNA after Moh-4 cells were treated with PHI. P15 mRNA was measured by RT-PCR. Pl5 protein was detected by Western blotting. Results Hypermethylation of gene pl5 was apparently attenuated and activation of transcription p15 gene was de novo after 5 days exposure to PHI. PHI enhanced both the expression of p15 mRNA and p15 protein in a concentration-dependent manner. The ratio of the gray scale of p15 mRNA strap was 0.17±0.12 in control, 0.29±0.14 in PHI 10 μmol/L, 0.55±0.07 in PHI 20 μmol/L, 0.93±0.13 in PHI 40 μmol/L. Conclusion PHI could active demethylation and transcription of gene p15.

BACKGROUND: Inflammation plays an important role in vessel proliferation after balloon injury. Reducing inflammatory reaction may lighten the ocurrence and development of the restenosis after angioplasty. Studies have demonstrated that PPAR_Y excitomotor has inhibitory effects on inflammation development. OBJECTIVE: To observe the changes in inflammatory factors after carotid artery balloon injury in rats and the intervention of PPARy excitomotor rosiglitazone. DESIGN, TIME AND SETTING: The randomized, controlled animal experiment was performed at the Central Laboratory of Shenzhen People's Hospital from January to June 2009. MATERIALS: Male SPF SD rats weighing about 350 g were selected to generate models of carotid balloon injury. METHODS: SD rats were equally and randomly divided into 3 groups: the control group, the balloon injury group and the rosiglitazone group. The left common carotid arteries were injured by balloon in the balloon injury group and the rosiglitazone group. The control group received sham operation. The rosiglitazone group was administered rosiglitazone daily by gavage,which began 4 days before operation and continued until harvesting.Accordingly,the control group and the balloon injury group were administered normal saline daily by gavage. MAIN OUTCOME MEASURES: All rats were executed under anesthesia at 14 days after operation, respectively to harvest left common carotid artery samples. The vessels were stained by hematoxylin-eosin, and Neointimal area (NIA) and media area (MA) as well as NIA/MA were calculated. Real time RT-PCR and Western Blot method were used to assay the expression of interleukin (IL)-6, IL-10, IL-17A mRNA and the distribution of nuclear factor (NF)-kB protein. expression levels of IL-6 and IL-17A mRNA in the rosiglitazone group were significantly lower than the balloon injury group, but higher than the Control group( P < 0.05), The expression levels of IL-10 mRNA in the rosiglitazone group were higher than the the rosiglitazone group was down-regulated, and lower than the balloon injury group, but higher than control group (P < 0.05). CONCLUSION: Rosiglitazone can regulate the expression of II-6 IL-10 IL-17A mRNA and the balance of inflammatory factors via NF-kB,inhibit the inflammatory reaction of injured vessels and may contribute to lighten the restenosis of injured vessels.

Objective:There is a large of population of macrophages resident in the testicular interstitial tissue under normal conditions and they are increased during inflammation.The mechanisms involved are unclear.This study focused on the expression of monocyte chenoattractant protein-1 (MCP-1) in the mouse testis before and after an intraperitoneal injection of LPS.Methods:The expression of MCP-1 in testis was detected by using reverse transcription-polymerase chain reaction and Western blot,the immunofluorescent technique was used to detect the localization of MCP-1 protein in testis.Results:In the normal testis,the expression of MCP-1 mRNA and protein was detectable by RT-PCR and immunofluorescent technique,respectively.The level of testicular MCP-1 mRNA increased dramatically at 3-24 h after LPS treatment,the level of MCP-1 protein increased at 12 h after LPS treatment.The MCP-1 was localized in the testicular interstitial tissue.Conclusion:MCP-1 may play a role in maintaining the resident macrophage population in normal testis and regulating monocyte and macrophage influx in inflammatory testis.

Objective To investigate phenyhexyle isothiocyanate (PHI) modulating histone acetylation and inhibiting Akt signaling pathway in prostate cancer cell line PC3 in vitro. Methods Apoptotic cells were measured by TUNEL assay. Histone acetylated H3, H4 and the Akt protein signaling pathway (Akt, p-Akt, mTOR, p-mTOR, p70S6K and p-p70S6K) were detected by Western blot. Results Apoptotic cells increased after exposure to PHI with concentration dependent. PHI significantly induced an accumulation of histone acetylated H3, H4. The change of Akt, mTOR, p70S6K proteins was not observed. Phosphorylation of Akt (p- Akt), mTOR (p-mTOR) and p70S6K (p-p70S6K) decreased after exposure to PHI for 7 h. Conclusions PHI can induce histone acetylation H3, H4 accumulation. PHI inhibits Akt signaling pathway resulting cell apoptosis. It might be a new anticancer agent.

DCD WeChat ethical review had its necessity and superiority but problems and confusion as well. For instance, WeChat review time was urgent and limited;WeChat review discussed insufficiently even hard to car-ry out;the methods of WeChat review were limited;the authenticity of audit opinion was difficult to grasp;the re-view data privacy existed hidden danger;the review quality was difficult to guarantee;WeChat conference content file archive was difficult, and so on. As to this, the author put forward the following countermeasures:giving war-ranty on the ethical review time as far as possible;initiating the committee review by the referee and uploading the review information to WeChat group, then ethical reviewers expressing their opinions in real names to ensure data confidentiality and privacy protection; strengthening the ethics committee education for organ transplantation; im-proving the quality of the review committee members and moral cultivation;archiving the WeChat conference infor-mation.

Objective To investigate the sleep quality of cancer patients before and after cancer so as to take effective measures to improve sleep quality of cancer patients.Methods In Xinjiang autonomous region,72 cancer patients in the Department of Oncology and Radiotherapy were surveyed for the study group and 61 benign patients as control group.The instruments including self-made general status and sleep status survey before cancer,and the Pittsburgh sleep quality index scale were used respectively.Results In the study group,40 people had sleep disorders (55.5％) before the cancer,significantly higher than control group people in 15 (24.5％),and the total Pittsburgh sleep quality index (PSQI) scores on average (14.00 ±2.39) were significantly higher than the control group (11.19 ± 2.45).The PSQI had seven sleep quality factors,with the statistical differences between two groups (P ＜ 0.05).Conclusions Chronic insomnia patients are more prone to cancer,cancer patients sleep quality is poorer,and the adjustment of the sleep disorders has more importance.Paying more attention to the regulation of cancer patients to sleep helps to improve the patient's quality of life.
