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.

Korean Journal of Urology 1995;36(9):976-983
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 explore the expression of tankyrase (TNKS) and its relationship with WNT/β-catenin signal?ing pathway in lung acinar adenocarcinoma. Methods Seventy-two samples of single subtype alveolar like lung adenocarci?noma (lung adenocarcinoma group) and 67 specimens of normal lung tissue adjacent to carcinoma (adjacent to carcinoma group) were collected. Immunohistochemical method was used to detect expressions of TNKS, beta-catenin (β-catenin) and c-myc protein. The correlation of each protein expression in lung adenocarcinoma tissues was analyzed. The differential ex?pression of TNKS was detected by Western blot assay in two groups. Results Tankyrase protein was mainly expressed in cy?toplasm. The expression ofβ-catenin protein was mainly in cytoplasm and nuclear of lung adenocarcinoma. The expression ofβ-catenin was mainly in cytoplasm, and a small amount was in nuclear of the adjacent group. The c-myc protein was ex?pressed mainly in the nucleus. The positive expression rates of TNKS,β-catenin and c-myc protein were significantly high?er in lung adenocarcinoma group than those of adjacent to carcinoma group (P<0.05). The expression ofβ-catenin in cyto?plasm and nucleus was positively correlated with the expression of TNKS and c-myc (P<0.05). Western blot analysis showed that the relative expression level of TNKS was significantly higher in lung adenocarcinoma group than that of adja?cent to carcinoma group (0.497 ± 0.021 vs. 0.237 ± 0.015, t=13.00, P<0.01). Conclusion Abnormally high expression of TNKS in lung adenocarcinoma may promote the occurrence of lung cancer by regulating the WNT signaling pathways. Inhib?iting TNKS expression may become a new target to treat lung adenocarcinoma.

Objective To report the clinical outcome and prognostic factors for locally recurrent nasopharyngeal carcinoma(NPC)treated with intensity modulated radiotherapy(IMRT).Methods From January 2001 to August 2004,the data of 132 such NPC patients were analyzed retrospectively;104 male and 28 female with a median of 44.5 years(range 21-73 years).Ninety-eight patients(74.2%)were confirmed by biopsy as having NPC:9 with WHO TypeⅡand 89 WHO TypeⅢ.The other 34 patients were only diagnosed by MRI scan because of the extension/invasion was in the base of skull and/or cavernous sinus.Median interval time were 24 months(range 6-184 months).According to the 1992 Chinese Fuzhou Staging System:stageⅠ3.8 %,Ⅱ10.6 %,Ⅲ22.0% andⅣa 63.6%;T1 5.3%,T2 10.6%,T3 22.7% and T4 55.3%.Twenty-two patients had recurrence in the neck lymph nodes.IMRT was given with the sequential tomotherapy system(NOMOS Peacock systems)of 6 MV X-rays.Prescription dose was 60-70 Gy in GTV,with the fractional dose of 1.94-2.8 Gy.Sixty patients were also supplemented with two to six courses of cisplatin-based chemotherapy.Results The median volume of GTV was 39.5 cm~3(range 0.8-158.9 cm~3).The D95,V95,mean dose and fractionation dose of GTV was 66.9 Gy,98.3%,69.8 Gy and 2.32 Gy,respectively.The median follow-up time was 12 months(range,2-47 months).The 1-,2-and 3-year local progression-free rate was 96.4%,88.4% and 85.3%,respectively.The overall 1-,2-and 3-year survival rate was 6.5.9%,49.6% and 41.6%,respectively.Eleven patients developed distant metastases.Forty-seven patients were observed to devdop mucosa necrosis and/or massive hemorrhage in the nasopharynx.On univariate and multivariate analysis,fractional dose and vohane of GTV were significant prognostic factors for overall survival(P=0.016,0.009).Conclusions The local control and survival rate can be improved for patients with locally recurrent nasopharygeal carcinoma after treatment of intensity modulated radiotherapy.The fractional dose and volume of GTV are independent prognostic factors for the overall survival. The main death reasons are mucosa necrosis and/or massive hemorrhage in the nasopharynx.

Objective The aim of the study was to analyze the predictive value of the European system for cardiac operative risk evaluation score (EuroSCORE) and the Society of Thoracic Surgeons predicted risk of mortality (STS-PROM) in -dult patients undergoing aortic valve replacement (AVR).Methods We carried out a retrospective statistical analysis on 521 adult patients undergoing AVR between 1999 and 2008 in Changhai hospital.Patients with concomitant coronary artery bypass grafting were also included.Excluded from this study were patients having surgery for congenital heart defects,aneurysm of thoracic aorta and atrial fibrillation.Operative mortality was defined as death before discharge from the hospital.The mortality risk calculation of EuroSCORE and STS-PROM for aortic valve procedures was performed by the online available EuroSCORE or STS score calculator.Based on the additive EuroSCORE risk calculation,patients were divided into low-risk,medium-risk and high-risk groups.The valuation of three different algorithms depended on the assessment of two features:calibration and discrimination.A comparison of observed and predicted mortality rates was also performed.Results A total of 521 patients were identified as having undergone aortic valve replacement.In-hospital mortality was 4% (21 cases) overall.The expected mortality for the additive,logistic EuroSCORE and the STS-PROM was 3.36%,2.82% and 1.25%,respectively.The observed to expected ratio was 1.2 for additive EuroSCORE,1.43 for logistic EuroSCORE and 3.23 for STS-PROM.The STS-PROM underpredicted observed mortality significantly ( P < 0.01 ) and showed poor calibration in predicting in-hospital mortality in the entire cohort,medium- and high-risk subgroups.The logistic EuroSCORE underpredicted observed mortality in the mediumrisk subgroup ( P < 0.05 ).EuroSCORE underpredicted in-hospital mortality in the high-risk subgroup with the observed-expected mortality rate of 1.84 for additive EuroSCORE and 1.46 for logistic EuroSCORE.The EuroSCORE in three subgroups showed poor discrimination in predicting mortality as well as the STS-PROM did in the medium- and high-risk subgroups ( ROC < 0.7).Conclusion Both the EuroSCORE and the STS-PROM give an imprecise prediction for individual operative risk in patients undergoing aortic valve replacement in our study.These algorithms seem unsuitable to identify a high-risk patient population undergoing isolated AVR.It is necessary to construct a risk stratification model for valve surgery according to the profiles of Chinese patients.
