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.

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.

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.

BACKGROUND: Cells in contact with nanomaterials can induce oxidative stress, allergic reactions, and then produce cytotoxicity and genotoxicity. Therefore, studies on nano toxicology have attracted more and more attention.OBJECTIVE: To comparatively evaluate the cytocompatibility of Pluronic (P85, F127, F87) tri-block copolymer nanoparticles modified with folic acid (FA) and polylactic acid (PLA).METHODS: Pluronic (P85, F127, F87) tri-block copolymer nanoparticles were modified with FA and PLA to synthesize a variety of amphiphilic block copolymers, including PLA-P85-PLA, FA-P85-PLA, PLA-F127-PLA, FA-F127-PLA,PLA-F87-PLA and FA-F87-PLA. The cytotoxicity of these synthesized nanoparticles was analyzed by cell morphology,cell metabolic activity and cell membrane effects in HepG-2 cells.RESULTS AND CONCLUSION: The relative growth rate of HepG-2 cells had no significant differences under 24-hour induction of various concentrations (5, 10, 20, 50, 100 mg/L) of unmodified P85, F127, and F87 nanoparticles (P > 0.05).The growth and proliferation of cells under the low concentrations (5, 10, 20, 50 mg/L) were enhanced. P85 NPs and F87 NPs could significantly inhibit cell viability at dose of 400 mg/L. In contrast, there were no significant differences towards P85, F127 and F87 nanoparticles (5, 10, 20, 50, 100, 200, 400 mg/L) modified with FA and PLA when compared with the control group (P > 0.05). These findings indicate that the modification of FA and PLA can improve the cytocompatibility of Pluronic (P85, F127, F87) tri-block copolymers, and therefore, PLA-Pluronic-PLA and FA-Pluronic-PLA nanoparticles are both good candidates for drug vectors.

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.
