OBJECTIVETo observe the impacts of different frequencies of electroacupuncture (EA) on post-operative cognitive function and the change in serum S-100beta protein under the compound anesthesia of acupuncture and drugs.

METHODSOne hundred and twenty-four patients of abdominal operation at selective time were randomized into a routine drug anesthesia group (group A, 24 cases), a meridian point 2 Hz group (group B, 26 cases), a me ridian point 2 Hz/100 Hz group (group C, 25 cases), a meridian point 100 Hz group (group D, 24 cases) and a transcutaneous acupoint electric stimulation 2 Hz/100 Hz group (group E, 25 cases). In group A, the endotrachea-lgeneral anesthesia was applied. In the rest groups, the acupuncture anesthesia was induced for 30 min before the endotracheal general anesthesia, at Baihui (GV 20), Yintang (GV 29) and Neiguan (PC 6), with G6805-2 electric acupuncture apparatus used. In group B, the continuous wave and 2Hz in frequency were selected. In group C, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected. In group D, the continuous wave and 100 Hz in frequency were selected. In group E, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected, and the electrode pads were stick on the acupoints and connected with the electric stimulation till the end of operation. Mini-mental state examination (MMSE) was adopted to evaluate and record the changes in cognitive function 1 day before operation and on the 3rd day after operation. The conditions of post-operative cognitive dysfunction (POCD) in the patients and the changes in serum S-100beta protein were monitored before and at the end of operation.

RESULTSThe incidence rate of POCD on the 3rd day after operation was 41.7% (10/24) in group A. The incidence rates of POCD were 26.9% (7/26), 16.0% (4/25), 33.3% (8/24) and 16.0% (4/25) in group B, C, D and E separately. Compared with group A, the incidence rate of PCOD in group B, C, D and E were reduced (all P<0.05), the incidence rate in group C and E were lower than that in groups B and D (all P<0.05). At the end of operation, the level of serumS-100beta protein was (0.186 +/- 0.027) microg/L in group A, the levels were (0.165 +/- 0. 028) microg/L, (0.166 +/- 0.027) microg/L, (0.163 +/- 0.025) microg/L and (0.164 +/- 0.025) microg/L in group B, C, D and E separately. The levels of serum S-100beta protein in group B, C, D and E were lower than that in group A separately (all P<0.05).

CONCLUSIONThe general anesthesia assisted with EA at different frequencies reduces the incidence of cognitive dysfunctionand, decreases the level of serum S-100beta protein after intestinal cancer resection. The effects of the meridian point electric stimulation at 2 Hz/100 Hz and the transcutaneous electric stimulation at 2 Hz/100 Hz are the best. Hence, these two approaches of anesthesia deserve to be recommended practically.

OBJECTIVETo explore the effect of acupuncture-anesthetic composite anesthesia (AACA) on the incidence of postoperative cognitive dysfunction (POCD) and changes of TNF-alpha, IL-1beta, and IL-6 in elderly patients.

METHODSTotally 83 patients undergoing surgical resection of gastrointestinal tumor were randomly assigned to the simple anesthesia group (A group, 41 cases) and the AACA group (B group, 42 cases). Patients in Group A received endotracheal general anesthesia. Those in Group B were induced by acupuncture anesthesia for 30 min by needling at Baihui (DU20), Neiguan (PC6), Zusanli (ST36). The electro-acupuncture (EA) apparatus was connected after arrival of qi, with the wave pattern of density 2/100 Hz. The stimulus intensity was set by patients' tolerance, with the peak current of 5 mA. Then the endotracheal general anesthesia was performed and the EA lasted till the end of the surgery. The cognitive function of all patients was assessed before operation and at day 3 after operation using mini-mental state examination (MMSE). POCD was confirmed if with one or more decreased stand- ard. The peripheral venous blood was collected before anesthesia induction (TO), immediately at the end of surgery (T1), 24 h after operation (T2), and 48 h after operation (T3), and serum concentrations of IL-1beta, IL-6, and TNF-alpha were correspondingly measured using ELISA.

RESULTSThe postoperative anesthesia awakening time was shorter in Group B than in Group A [(20.37 +/- 6.09) min vs (29.24 +/- 7.48) min, P < 0.05]. The remifentanil dose used during the operation was less in Group B than in Group A (P < 0.05). The incidence of POCD at day 3 was lower in Group B than in Group A [10/41 (23.8%) vs 15/42 (36.5%), P < 0.05]. The concentrations of IL-1beta, IL-6, and TNF-alpha at T1-T3 were higher than those at TO in the two groups (P < 0.05). The increment of TNF-alpha and IL-1beta was less in Group B than in Group A (P < 0.05). CONCLUSION AACA could reduce the incidence of POCD and inhibit postoperative release of TNF-alpha, IL-1beta, and IL-6 in elderly patients undergoing colorectal cancer resection.

OBJECTIVETo analyze the influence of intravesical Pirarubicin (THP) instillation on the prediction results of European Organization for Research and Treatment of Cancer (EORTC) risk tables and to discuss the efficacy of EORTC risk tables in clinical application.

METHODSWe retrospectively reviewed the clinical data of 389 patients with non-muscle invasive bladder cancer after TURBT treated with intravesical pirarubicin instillation. According to the EORTC Scoring System, all the cases were divided into low risk group, intermediate risk group and high risk group. The 1-year and 5-year recurrence and progression rates of each group were calculated and compared with the prediction results of the EORTC risk tables.

RESULTSThe 1-year recurrence and progression rates of the low risk group were 8.0% and 0, those of the intermediate risk group were 31.0% and 2.8%, and those of the high risk group were 52.5% and 18.6%, respectively. The 5-year recurrence and progression rates of low risk group were 16.0% and 5.3%, those of the intermediate risk group were 42.6% and 10.7%, and those of the high risk group were 63.9% and 41.9%, respectively. The prediction results of progression rate were similar to that of the EORTC risk tables while the overall recurrence rate was lower.

CONCLUSIONSThe EORTC risk tables can be effectively used to predict the recurrence rate and progression rate of non-muscle invasive bladder cancer. However, the EORTC risk tables have a tendency to overestimate the recurrence rate. Intravesical pirarubicin instillation is helpful to reduce the recurrence rate, yet has no obvious influence on the tumor progression.

OBJECTIVETo investigate the predisposing role of HLA-DRB1, DQB1 genes in pemphigus vulgaris (PV).

METHODSPolymerase chain reaction-specific sequence primers method was used to type HLA-DRB1, DQB1 subregion in the patients with PV of Han nationality from Jiangsu and Anhui provinces and matched control subjects.

RESULTSDR4, DRB1*14(*1401,*1404,*1405) gene frequencies in PV patients were significantly higher than those in controls (Pc<0.05 and Pc<0.01 respectively). DQB1*0302, DQB1*0503 gene frequencies were significantly higher in PV patients (Pc<0.05). Further typing of DR4 positive subjects revealed that the gene frequencies of DRB1*0406, *0403 were significantly increased in PV patients as compared with controls (Pc<0.05). The haplotype frequencies of HLA-DRB1*04, DQB1*0302 and HLA-DRB1*14, DQB1*0503 in PV patients were significantly higher than those in controls (P<0.05).

CONCLUSIONThe results suggest that the combination of HLA-DRB1*4, DQB1*0302 and HLA-DRB1*14, DQB1*0503 forms putative susceptible haplotypes for PV patients in Chinese Hans.

AIM:To investigate the effect of growth hormone receptor(GHR) knockdown on nuclear factor-κB (NF-κB) activity and inflammatory cytokine production stimulated by growth hormone (GH) in 3T3-L1 adipocytes. METHODS:The specific siRNA for GHR was transfected into 3T3-L1 adipocytes to silence GHR expressions. The effects of GH on NF-κB activation and inflammatory cytokine production in 3T3-L1 adipocytes transfected with siRNA-GHR or siRNA-control were measured by dual-luciferase system analysis,real-time RT-PCR and ELISA. RESULTS:The protein expression of GHR was diminished after transfection with GHR specific siRNA. Dual-luciferase reporter system analysis re-vealed that GHR knockdown resulted in attenuation of GH-stimulated NF-κB activation in the 3T3-L1 adipocytes. GHR knockdown ameliorated the GH-induced production of inflammatory cytokines TNF-α,IL-1β,IL-6,MCP-1 and MIP-1α in the 3T3-L1 adipocytes. CONCLUSION:Knockdown of GHR might be efficacious to prevent GH-induced inflammatory re-sponses in the 3T3-L1 adipocytes.
