Objective To explore the effect of different doses remifentanil on hyperalgesia and the analgesic effect of gynecological laparoscopic operation.Methods Ninety gynecologic laparoscopic operation patients were divided into A group,B group and C group by random digits table method with 30 cases each.The anesthesia induction in A group and B group was intravenous injection remifentanil 1.5 μ g/kg,propofol 2 mg/kg,cisatracurium 0.2 mg/kg,and in C group was intravenous injection fentanyl 3 μ g/kg,propofol 2 mg/kg,cisatracurium 0.2 mg/kg.The maintenance of anesthesia in A group was infusion of remifentanil 0.3 μ g/ (kg· min),in B group was infusion of remifentanil 0.2 μ g/ (kg· min),and in C group was infusion of fentanyl 2 μ g/kg.The operation time,anesthesia time,time to extubation,intraoperative doses of propofol and remifentanil (A group and B group) were recorded.The visual analogue score (VAS) before operation and 15,30,60,120,240 min after extubation were recorded.The analgesia time,number of analgesia and adverse reaction after extubation were observed.Results There were no statistical differences in operation time and anesthesia time among 3 groups (P ＞ 0.05).The extubation time in A group and B group was significantly shorter than that in C group:(5.9 ± 2.7) and (6.1 ± 2.3) min vs.(9.6 ± 3.3) min,the dose of propofol in A group was significantly lower than that in B group and C group:(461.3 ± 69.7) mg vs.(543.4 ± 101.9) and (552.5 ± 93.8) ng,the dose of remifentanil in A group was significantly higher than that in B group:(1.12 ± 0.33) mg vs.(0.71 ± 0.1 l) mg,there were statistical differences (P＜ 0.05).The VAS 15,30,60,120,240 min after extubation in 3 groups were significantly higher than those before operation,A group:(7.3 ± 1.2),(7.4 ± 1.3),(6.5 ± 0.8),(4.5 ± 0.6),(4.1 ± 0.3) scores vs.(1.2 ± 0.3) scores,B group:(6.4 ± 1.5),(6.6 ± 1.1),(5.3 ± 0.4),(4.6 ± 0.3),(4.0 ± 0.4) scores vs.(1.5 ± 0.4) scores,C group:(3.4 ± 0.5),(4.2 ± 0.8),(4.1 ± 0.6),(3.8 ± 0.7),(3.8 ± 0.6) scores vs.(1.4 ± 0.2) scores,there were statistical differences (P ＜ 0.05).The VAS 15,30,60 min after extubation in A group were significantly higher than those in B group,and the VAS 15,30,60,120 min after extubation in A group and B group were significantly higher than those in C group,there were statistical differences (P ＜ 0.05).There was no statistical difference in VAS 240 min after extubation among 3 groups (P ＞ 0.05).The number of analgesia in A group,B group and C group were 28,29 and 3 cases,and the analgesia time were (16.1 ± 4.6),(17.9 ± 5.8) and (68.5 ± 10.l) min,there were statistical differences (P＜ 0.05),there were no statistical differences between A group and B group (P＞ 0.05),and there were statistical difference between A group,B group and C group (P ＜ 0.05).There was no statistical difference in adverse reaction among 3 groups (P ＞ 0.05),and there was no respiratory depression in 3 groups.Conclusion The degree of hyperalgesia is related to the dose of remifentanil during gynecologic laparoscopic operation.

Objective To investigate the plasma 8-iso-prostaglandin F2α(8-iso-PGF2α and the serum C-re-active protein(CRP) levels in patients with obstructive sleep apnea-hypopnea syndrome(OSAHS) with and without hypertension(OSAHS + HT),and to explore the changes of pathophysiology in patients with OSAHS and the patho-genesis of OSAHS + HT. Methods All observed subjects were divided into 3 groups: control group (n=20),OS-AHS group(n=19),OSAHS + HT group (n=21). Plasma 8-iso-PGF2αand serum CRP concentrations levels were measured by ELISA and were compared. Results The plasma 8-iso-PGF2αand serum CRP levels,were higher in OSAHS patients than those in control subjects [(11.08±3.26)μg/L vs (7.49±2.10)μg/L,P<0.01;(1.75±0.82) mg/L vs (0.52±0.26 ) mg/L,P<0.01],and were higher in OSAHS + HT group than those in control group [14.84±3.43)μG/L vs(11.08±3.26)μg/L,P<0.01 ;(3.13±1.06)mg/L vs(1.75±0.82)mg/L,P<0.01]. Conclusions Oxidative stress and inflammation in OSAHS patients are increased,which are involved in the devel-opment of OSAHS associated hypertension.

Objective To investigate the hMOF protein expression in non?small cell lung cancer and explore the relationship between its expres?sion and radiotherapy prognosis. Methods Immunohistochemical staining was used to detect the hMOF expression in 59 cases of non?small cell lung cancer after radiotherapy. The relationship between hMOF expression with clinicopathological and radiation prognosis was analyzed. Results Among the 59 cases of non?small cell lung cancer tissues,there were 30 cases found to be high expression with hMOF. The rate of positive expression of hMOF in non?small cell lung cancer were 50.85%. Clinical stage and hMOF expression were independent predictors for non?small cell lung can?cer. Conclusion The expression of hMOF had a positive correlation with the radiation prognosis in non?small cell lung cancer,which could be used as a prognostic indicator of radiotherapy.

Retrospectively from February, 2006 to June, 2009 the clinical characteristics of 14 misdiagnosed cases of insulinoma in the First Affiliated Hospital of Zhengzhou University were analysed. The rate of misdiagnosis was 38% ( 14/37). The rate of IRI/G≤0. 3 was 33%. Insulinoma has often been misdiagnosised when IRI/G≤0. 3. Hence a diagnosis of insulinoma can not be excluded with this IRI/G rate.

We have studied general patient characteristics, the early and late postoperative complications associated with each procedure and the results of urodynamic studies in 29 patients who had received various kinds of urinary diversion at the Dept. of Urology, Dong-A University Hospital from May 1990 to May l994. The results are as follows. 1. Of 29 urinary diversions, ileal conduit was performed in 18 patients, appendicoureterocutaneostomy in 2, Indiana pouch in 8 and rectal pouch in l. The surgical indications were bladder tumor in 28 and pelvic actinomycosis in 1 2. Sex ratio between male and female was 22:7. Average age according to each procedure was 67,4 years old in ileal conduit group, 62.5 years old in appendicoureterocutaneostomy, 54.3 years old in lndiana pouch, and 33.0 years old in rectal pouch. Average operative time ranged from 275.5 to 647.5 minutes. with lndiana pouch group taking maximum time and appendicoureterocutaneostomy group taking the least time. 3. There was no change in postoperative renal function and serum electrolytes. Concerning the period of hospital stay, ileal conduit in 21.3 days, Indiana pouch group was 28.7 and appendicoureterocutaneostomy in 20.5 days being the shortest of all. 4. Wound infection was most common early postoperative complication occurring in 5 out of 29 patients. Anastomotic leakage was seen in 2 out of 18 ileal conduits, 2 paralytic ileus in ilea1 conduit and lndiana pouch each. 5. Six months postoperative cystometric studies show the average volume and average reservoir pressure of 533.3ml and 22.7cmH2O in lndiana pouch and 38.0cmH2O in rectal pouch which is greater than the maximum intraluminal pressure. In conclusion, the author believes that the urologic surgeon should be familiar with several procedures, because these procedures should be tailored to the patient's anatomy, prior surgery, renal function and preference.

Objective To evaluate the outcomes and toxicities of early stage nasopharyngeal carcinoma(NPC)patients treated with intensity-modulated radiotherapy(IMRT)alone. Methods From February 2001 to January 2008, 198 early stage NPC patients according to AJCC/UICC 2002 staging system were treated by radical radiotherapy with IMRT technique in our institute, the clinical data were analyzed retrospectively. Results The 5-year disease-specific survival, local recurrence-free survival(LRFS)and distant metastasis-free survival(DMFS)were 97.3%, 97.7% and 97. 8% respectively. The 5-year LRFS for T1, T2 patients were 100%, 96. 7%(x2 = 2. 24 ,P = 0. 135)respectively. The 5-year DMFS for T1 N0,T2N0, T1N1, and T2N1 patients were 100%, 98. 8%, 100% and 93. 8%(x2= 2. 35, P= 0. 125)respectively. Grade 1 and 2 mucositis and pharyngitis were most common acute toxicities. Radiation encephalopathy and cranial nerve injury were not observed in all patients. Conclusions IMRT alone for early stage NPC patients can produce satisfactory results and acceptable treatment-relative toxicities. Patients with T2b and T2bN1 had a relatively higher incidence of local recurrence and distant metastasis, which suggested that combination of IMRT and chemotherapy may improve clinical results in those patients.

Objective To investigat the prognostic value of overall treatment time (OTT) for locally advanced nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT).Methods From May 2001 to April 2007, 376 patients with locally advanced NPC treated with IMRT were retrospectively analyzed.All patients were divided into OTT≤45 days group and OTT >45 days group.The treatment outcomes between the two groups were analyzed.Results Between the groups with OTT≤45 days and OTT > 45 days, the 2-year local control rate (LCR) was 94.9% and 93.1% (χ2= 2.83, P > 0.05) for all patients, 96.3% and 98.7% (χ2=2.83, P>0.05) for patients with T3 disease, 92.2% and 83.1%(χ2= 6.30, P < 0.05) for T4, and 93.1% and 97.5% (χ2= 4.69, P = 0.030) when chemotherapy was concurrently administered.The 2-year LCR was 98%, 96% and 93% (χ2= 2.20, P = 0.531) for patients with treatment interruption before, within and after the 3rd week of IMRT, The Cox regression analysis found that OTT was an independent prognostic factor for LCR in T4 disease.The Linear regression showed that the 2-year LCR was decreased by 2.7% per day of delay.Between the groups with OTT≤45 days and OTT >45days, the 2-year estimated disease-specific survival (DSS), distant metastasis-free survival (DMFS) and overall survival (OS) were 84.1% vs.78.7% (χ2= 0.02, P = 0.881), 87.0% vs.86.1% (χ2= 0.85,P = 0.358), and 91.7% vs.92.2% (χ2= 0.06, P = 0.806), respectively.The further stratified analysis found that the DSS, DMFS and OS were similar between the two groups in T3 (83.7% vs.83.2%, χ2=0.07, P=0.798;86.6% vs.85.7%,χ2=0.02, P = 0.898 ; and 93.7% vs.94.8%,χ2=0.03, P=0.862) and T4 disease (81.4% vs.72.3%, χ2= 0.16, P = 0.687 ;82.6% vs.86.9%, χ2= 1.78, P =0.182;and 88.3% vs.87.5% ,χ2=0.60, P =0.438).In multivariate analysis, T-stage and N-stage were the independent prognostic factors for both DFS and OS, and N-stage was the independent prognostic factor for DMFS.Conclusions The prolongation of the overall treatment time decrease the local control of patients with T4 NPC.

Objective To compare the Chinese'92 and 2008 staging systems of nasopharyngeal carcinoma (NPC) based on the long term survival of the patients. Methods Clinical data of 498 NPC patients treated with definitive IMRT were retrospectively analyzed. The distributions of patients in the two staging systems were compared. The long term outcomes according to T, N and overall stages in each system were evaluated. Kappa value and Pearson coefficient were used to evaluate the agreement and correlation of the two systems. Results The distributions of both T and N stage between'92 and 2008 stage systems were different. In both staging systems, the local recurrence-free survival (LRFS) curves of T_1, T_2 andT_3 were close up (even overlaped), though they were apart from T_4. The distant metastasis-free survival (DMFS) curves overlaped of N_1 and N_2 in the'92 staging system, while separated of N_1, N_2 and N_3 in the 2008 staging system. Significant difference of DMFS was not found between N, and N_2 in'92 staging system, while did exist among N_0, N_1, N_2 and N_3 stages in 2008 staging system. In the both staging systems, the disease-specific survival (DSS) of stage Ⅰ did not significantly differ from that of stage Ⅱ or Ⅲ. The statistical analysis showed the conformality of DSS curves in the two system was 89% (Kappa =0. 833 ,P <0.01), with agood relative rate (r=0. 919,P<0. 01). Conclusions The difference between'92 and 2008 staging system is mainly in N stage. The 2008 N stage seems more reasonable compared with'92 N stage, which is able to better forecast the DMFS. There are some agreements and correlations between the two staging systems.
