Objective To compare the quality of life at baseline and at 3 months after coronary artery bypass grafting(CABG) and investigate the related risk factors. Methods The prospective study included 121 consecutive patients reaching inclusion criteria and undergoing CABG between June 2009 and May 2016. Health status survey was measured with short form-36(SF-36)at baseline and at 3 months after CAGB. Change of quality of life and influencing factors and quality of life were analyzed. Results Eight domains including physical functioning ,role-physical ,bodily pain,general health,vitality,social functioning,role-emotional and mental health and two component summaries including physical component summary(PCS)and mental component summary (MCS)of SF-36 were significantly improved at 3 months following CAGB(all P<0.01). Moreover,advanced age, women,diabetes mellitus,assisted ventilation time,hospital stay and use of t-PA were relative to the PCS after CAGB. Conclusions The findings demonstrate quality of life is significantly improved at 3 months post CAGB. Advanced age,underlying disease,serious disease,women and lower PCS score prior to CAGB are linked with low PCS after CAGB.

Objective To observe the clinical efficacy of acupuncture plus Chinese medicinal fumigation in treating chronic pelvic inflammatory disease (CPID).Method Totally 120 CPID patients were randomized into group A, group B and group C, 40 cases in each group. Group A was intervened by acupuncture plus Chinese medicinal fumigation, group B was by dry acupuncture treatment, while group C was by Chinese medicinal fumigation alone. After 3 treatment courses, the clinical efficacies were observed, and the relapse rates among the cured cases in 8 months after the whole treatment were compared among the 3 groups.Result The total effective rate and recovery rate were respectively 95.0% and 70.0% in group A, versus 82.5% and 45.0% in group B, and 57.5% and 32.5% in group C, and the total effective rate and recovery rate in group A were significantly different from that in group B and group C (P<0.05). The treatment duration for the recovered cases in group A was significantly different from that in group B and C (P<0.05). The relapse rate in the recovered cases in the 8-month follow-up was 10.7% in group A, versus 44.4% in group B and 53.8% in group C, and the relapse rate in group A was markedly lower than that in group B and C (P<0.05).Conclusion Acupuncture plus Chinese medicinal fumigation is an effective method in treating CPID, and its advantages include content efficacy, short treatment duration, and low relapse rate, etc.

Objective To investigate the inhibitory effect of reiniosidc C (RC) on asymmetric dimethylarginine (ADMA)-induced soluble interacellular adhesion molecule-1 (slCAM-1) expression and its mechanisms. Methods Human umbical vein endothelial cells (HUVEC 12) were cultured.The level of slCAM-1 in the conditioned medium was determined by ELISA. Changes in intracellular reactive oxygen species (ROS) levels were determined by measuring the oxidative conversion of cell permeable 2', 7'-dichlorofluorescein diacetate (DCFH-DA) to fluorescent dichlorofluorescein (DCF) in fluorospectro- photometer, and the nuclear factor-κB (NF-κB) DNA-binding activity was determined by electrophoretic mobility shift assays (EMSA). Results sICAM 1 expressions [(138.02±16.40), (194.52±11.14), (274.28±13.11)ng/L]and the generation of ROS[(75.64±5.22),(100.18±11.15),(107.23±13.45)units] in HUVEC-12 were time dependently increased by ADMA (30 μmol/L). Furthermore, thc generation of ROS [(85.33±8.68), (70.69±7.65),(59.12±4.15)units], activation of NF-κB activity and expression of sICAM-1 [(336.58±23.32),(203.27±25.18) ,(174.13±14.53)ng/L] induced by ADMA were inhibited by reinioside C (1,3,10μmol/L) in a dose-dependent manner. This effect was found to be the same by L-arginine (0.5 mmol/L) as NOS substrate and by pyrrolidine dithiocarbamate (PDTC) (10 μmol/L)as inhibitor of NF-κB.Conclusions Reinioside C attenuates the increase of sICAM-1 induced by exogenous ADMA

Objective To evaluate the efficacy of dexmedetomidine for improvement of postoperative analgesia with sufentanil in pediatric patients with a large area of burn after tangential excision and skin grafting.Methods Forty-two pediatric patients of both sexes with a large area of burn,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,aged 2-10 yr,weighing 13-36 kg,scheduled for elective tangential excision and skin grafting under combined propofol-remifentanil-sevoflurane anesthesia,were randomly divided into 2 groups (n=21 each) using a random number table:sufentanil group (group Suf) and dexmedetomidine plus sufentanil group (group Dex-Suf).The patient-controlled intravenous analgesia (PCIA) was used for postoperative analgesia.PCIA solution contained sufentanil 2 μg/kg and granisetron 100 μg/kg in 100 ml of normal saline in group Suf,and contained dexmedetomidine 2.5 μg/kg,sufentanil 1.5 μg/kg,and granisetron 100 μg/kg in 100 ml of normal saline in group Dex-Suf.The PCA pump was set up with a 0.5 ml bolus dose,a 15 min lockout interval and background infusion at a rate of 2 ml/h after a loading dose of sufentanil 0.1 μg/kg.When Faces Pain Scale score＞2,sufentanil 0.1 μg/kg was injected intravenously as rescue analgesic.The consumption of sufentanil was recorded within 48 h after operation.Ramsay sedation scores at static and dynamic (during dressing changes) conditions were assessed after operation.The parents' satisfaction,requirement for rescue analgesics and incidence of adverse reactions such as agitation,nausea and vomiting were recorded after operation.Results Compared with group Suf,Ramsay sedation scores at static and dynamic conditions and patients' satisfaction scores were significantly increased,and the consumption of sufentanil,requirement for rescue analgesics and incidence of agitation,nausea and vomiting were significantly decreased after operation in group Dex-Suf (P＜0.05).Conclusion Dexmedetomidine significantly improves postoperative intravenous analgesia with sufentanil in the pediatric patients with a large area of burn after tangential excision and skin grafting,and combination of dexmedetomidine and sufentanil is recommended for this type of pediatric patients.

AIM: To inhibit the expression of tyrosinase gene in murine B16 melanoma cells by antisense nucleotide. METHODS: The antisense recombinant pcDNA3.1(-)-tyr was constructed and was used to infect murine B16 melanoma cells for expression of tyr antisense nucleotide. The effect of antisense nucleotide of tyr on the expression of tyr gene was detected by determination of the activity of tyrosinase and of the production of melanin, Dopa staining and electronic microscope. RESULTS: The tyr antisense recombinant was successfully constructed and injected into murine B16 melanoma cell. The activity of tyrosinase in B16 cells infected with pcDNA3.1 (-)-tyr decreased to 0.0498?0.0036, compared to the tyrosinase activity of 0.0916?0.0132 in the control cells without treatment (P

AIM: To construct pVAX1-GrB. METHODS: Lymphocytes from human laryngeal carcinoma tissue were separated from tumor tissue. The fragment of granzyme B (GrB) was amplified by RT-PCR and was recombined to the downstream of T7 promoter in the vector pVAX1. The construction was transfected into Hep2 cells with lipofectamine 2000. The expression of protein was identified by indirect immunofluorescent antibody assay. RESULTS: It has been proved that the sequence of the RT-PCR product was totally consistent with the data of GenBank by DNA sequencing analysis. The GrB cDNA fragment was cloned into the vector of pVAX1 in the right direction and the open reading fragment of GrB was maintained. The target protein was detected in the transfected Hep2 cells. CONCLUSION: The pVAX1-GrB plasmid was successfully constructed and expressed. [
