Chinese Journal of Primary Medicine and Pharmacy 2011;18(7):871-873
Objective To compare target-controlled infusion of propofol combined with remifentanil total intravenous anesthesia and intravenous combined with inhalation anesthesia in hemodynamic changes and side effects in elderly patients with laparoseopic cholecystectomy.Methods 56 ASA Ⅰ-Ⅱ patients aged >60 Y undergoing elective laparoscopie cholecystectomy were randomly divided into propofol-remifentanil target controlled infusion group (observation group)(n=28)and inhalation anesthesia group(using intravenous anesthesia was maintained with isoflurane inhalation)(n=28).HR,SBP,DBP,PETCO2,initial consciousness time,extubation time,side-effects were recorded at each time points.Results The change extent of HR and blood pressure in observation group was lower than inhalation anesthesia group.The initial recovery time,recovery time of spontaneous breathing and extubation time in the observation group Was better than anesthesia group(all P<0.05).The side-effects in observation group were significantly lower than inhalation anesthesia group(all P<0.05).Conclusion Laparoscopic cholecystectomy in elderly patients by target-controlled infusion of propofol combined with remifentanil total intravenous anesthesia could significantly inhibit the stress response,and effectively maintain the stability of hemodynamic,and rapid postoperative recovery,fewer adverse reactions.It Was an ideal anesthesia methods in elderly patients with laparoscopic cholecystectomy.

Obesity has a harmful impact on health and is imposed by both environmental and genetic factors. Recently, over 60 obesity-related susceptible loci have been identified through genome-wide association study. However, it still remained unknown whether these loci were specific or generalized to the ethnic groups for genetic distinction. This review summarized the obesity-related susceptible loci in Asian populations, which were recently identified among Europeans or Asians.

Objective: To investigate the effects and mechanisms of vitamin A on tracheal mucosal immunity. Method: The rat model with vitamin A deficiency (VAD) was established. By use of immunohistochemical, RT-quantity PCR and ELISA methods, the number of dendritic cells (DCs, OX-62 positive cells), the maturation of DCs (the positive areas of CD80 and CCR7), the pathogen recognition receptors (the positive areas of TLR2 and of TLR4) and TLRs signal transduction (the mRNA level of MyD88), as well as cytokines production in tracheal mucous membrane were detected. Results: In VAD rats, the number of DCs in trachea was increased, but the expressions of CD80 and CCR7 were similar with control group. The TLR2 and MyD88 mRNA levels were up-regulated, and IL-12 production was also raised. However, Th2 cytokines IL-4 and IL-6 were reduced significantly in protein and mRNA levels, and the production of IL-10 protein was declined compared with the control. Conclusion: In VAD rats, the number of DCs, receptors of pathogens recognition, and cytokines production in trachea mucosa were significantly changed. The affection of VAD on DCs may play important role in the impaired mucosal immunity of trachea.

Objective: To investigate the role of retinoic acid (RA) in the differentiation, and maturation of dendritic cells (DCs) derived from cord blood monocytes, and its mechanism. Method: Nine cord blood samples were collected from healthy and well nourished newborns. Monocytes were isolated and cultured in vitro. Cells were divided into 4 groups: control group; retinoid acid receptor ? (RAR? )agonist group (RA group); RAR? antagonist group (RO group) and agonist plus antagonist group (RA+RO group). Part cells were collected in D9, and the surface markers on cells were detected by flow cytometer. The mixed lymphocyte reaction (allo-MLR) was used to evaluate the ability of DC to induce proliferation of T cells and the influence by RA and RAR?. Th cytokines were measured in protein level by ELISA and in mRNA levels by RT-PCR to decipher the effect of RA and RAR? in the regulation of Th1/Th2 balance by DCs. Results: The differentiation and maturation of DCs were inhibited significantly in RA group compared with control group. When RO was added into the culture, the effects of RA can be reversed. After MLR , the suppression effect of RA on allo-T cell proliferation was inversed by RO. During the influence of DC on Th cell polarization, RO could inhibit the down-regulation of Th1 cytokine (IFN-?) as well as the up- regulation of Th2 cytokines (IL-4, IL-10) by RA, whether on protein levels or on mRNA levels. Conclusion: Retinoic acid inhibited the differentiation and maturation of DC derived from cord blood monocytes, reduced the ability to stimulate allo-T lymphocytes proliferation by DCs, and made immune response bias to Th2. RAR? plays a very important role in the regulation of RA on DCs.

Objective To observe the effect of intra-articular injection of CM-chitosan on nuclear factor κB (NF-κB) activation and nitric synthase expression in rat osteoarthritis cartilage,and to explore the mechanism of inhibition of joint destruction.Methods Thirty-six SD rats were randomly divided into three groups:A,B,C,12 in each group.Group A was the sham group,group B,C rats had the medial collateral ligaments cut off and part of medial meniscus were removed to establish osteoarthristis model.Group C rats were injected with 3% carboxymethyl chitosan intra-articularly 0.15 mg/kg 5 weeks later,and then repeated injection every 1 week.Animals were sacrificed 11 weeks after surgery.The gross changes of cartilage and the expression of NF-κB (P65) were compared by immunohistochemistry,the protein expression of I-κB and P65 in nucleus were detected by Western-bloting.Inducible nitric oxide synthase (iNOS) mRNA and protein expres-sion were analyzed by reverse transcription polymerase chain reaction (RT-PCR) and western blot.The general score of cartilage was analyzed by H test,the rest data was analyzed by one-way ANOVA.Results The cartilage degeneration scores pf group C (intra-articular injection of CM-chitosan group) were significantly less than those of group B.The protein expression of NF-κB of the articular cartilage in group C (106±7)was significantly lower than group B (147±8),the I-κB degradation was inhibited significantly in group C,and the expression of iNOS mRNA and iNOS protein were reduced in OA art~icular cartilage of arthritis rat chondrocytes,therefore,it had protective effect on articular cartilage.Conclusion CMC may inhibit NF-κB signaling pathway by inhibiting the degradation of I-κB in cartilage,which reduces iNOS mRNA and protein expression in rat osteoarthritis cartilage,thereby protects rat osteoarthritis cartilage cells.

Objective To explore the role of Kv channel interacting protein 1(KChIP1)in the process of epileptic seizure and the relationship between KChIP1 and gamma-aminobutyric acid-(GABA)ergic neurons.Methods Normal female Sprague-Dawley rats were treated with pentylenetetrazole to make acute pentylenetetrazole models of epilepsy.Laser Scanning Confocal Microscope(LSCM)combined with double-labeled immunohistochemical technique was applied to observe the expression of the KChIP1 and the GABAergic neurons in the hippocampus of rats.Results The number of KChIP1-postive neurons in the hippocampus was significantly increased in the acute pentylenetetrazole model rats(P<0.05).There was no significant difference in the number of double-labled neurons(P>0.05),nor of the GABA-postive neurons between the model rats and the controls.The ratio of double-labeled neurons/total positive neurons was 63.9% in the hippocampus.Conclusion The KChIP1 might be involved in epileptogenesis of pentylenetetrazole induced seizure.The KChIP1 was associated with GABAergic neurons,whereas it may be functionally different from GABA.
