Objective To analyze the expression stability of the three widely used reference genes β-glueuronidase (GUSB), glycera]dehydes-3-phosphate dehydrogenase (GAPDH), β2-microglobulin (β2-M) in Chinese lung cancer tissue specimens and normal lung tissue specimens. Methods Gene expression wasmeasured by quantitative real time PCR and expression stability was analyzed with two widely used softwares genorm and normfinder. Results The intra-and inter-group difference of GAPDH is maximum (The intra and inter-group s is 1.07 and 0.93 respectively, |△ Ct|=2.01±1.06; P =0.000). The mean of these three genes' Ct value is the most stable one analyzed by the two softwares. But the t test showed that the mean of Ct value of GUSB and β2-M is the unique combination that had the minimum intra-and inter-group difference, with no statistically significant differences between normal and malignant samples (The intra-and inter-group s is 0.53 and 0.79 respective]y, |△Ct|= 0.73±0.53; P =0.053). Conclusion It is inappropriate to normalize data derived from lung tissue specimens using one of these three housekeeping genes alone. Among the different combinations of these three genes, the mean of the Ct values of GUSB and β2-M is the best choice as the internal control of lung tissue specimens.

Object To explore the relationship of 25 (OH) D levels in cord and maternal peripheral blood to understand the maternal and neonatal vitamin D status in Songjiang District of Shanghai. Methods One hundred newborns delivered at the First People’s Hospital afifliated to Shanghai Jiaotong University and 20 pregnant women during November 2010 to January 2011 in Songjiang district were enrolled in the study. The levels of 25 (OH) D in cord and maternal blood were measured by ELISA and compared. Results Mean materna1 serum levels of 25 (OH) D was (23.42±5.23) nmol/L, and cord blood 25 (OH) D was (29.77±12.51) nmol/L. Maternal serum 25 (OH) D was positively correlated with cord blood 25 (OH) D (r=0.84, P<0.001). Conclusions This study shows that the prevalence of vitamin D deifciency in pregnant women is high in Shanghai Songjiang District, which could have adverse effects on newbowns.

60 yr, hypertension, diabetes mellitus, smoking, long term inactivity etc), and duration of operation. The incidence of DVT was 49.3% in control group, 30.0% in group CS alone, 15.0% in group CS + IPC1 and 23.3% in group CS + IPC2 (P

0.05);the frequencies of IFN-? gene +874 site T and A allele showed significant difference between case group and control group(P0.05).Conclusion T allele of IFN? gene+874 site might have a relationship with generation of ovarian cancer,TT genotype might be susceptibility genotype for ovarian cancer.

Objective To investigate the association between polymorphism of protein C inhibitor(PCI)gene G10877T and male infertility,and provide theoretical basis for treatment of male infertility.Methods PCR and sequencing technique were applied to detect PCI gene G10877 T polymorphism in 53 normal control and 102 male infertility.Results There were three genotypes of wild type(G/C),hybridization mutation(G/T)and pure mutation(T/T).The analysis of sequencing indicated that in sperums of a proportion of the male infertile patients,TGG in PCI gene G10877T mutated into TGT.The contrast of BLASTB indicated that this mutation made Trp in 271 position change into Cys.Compared with control group,TT genotypic frequency and T allelic frequency in male infertility group had significant differences(P

Objective To determine the factors contributing to the development of deep vein thrombosis (DVT) in the lower extremity in patients after hip or knee arthroplasty and hip fracture internal fixation.Methods One hundred and forty-seven consecutive patients receiving hip or knee arthroplasty and hip fracture internal fixation from 2004 to 2005 were included in this study. Their age ranged from 33 to 92 years. Duplex color ultrasonic inspection was performed on veins of the bilateral lower extremities before operation and 2 weeks after operation for detection of DVT. The patients were divided into a DVT group and a DVT-free group based on the development of DVT after operation. Detailed perioperative clinical information about the patients, surgery and anesthesia was collected.Results Lower extremity DVT was found in 42.2% of the patients after operation, while the incidence of proximal DVT was 2.7%. Compared with the DVT-free group, the usage rate and dosage of ephedrine increased significantly, the duration of anesthesia was significantly longer, and the white blood cell count (WBC) on the 1st postoperative day and the highest WBC count were significantly higher in the DVT group(P＜0.05). Logistic regression analysis indicated that the above factors were closely related to DVT.Conclusion Duration of anesthesia ＞ 3 h, ephedrine administration and a marked increase in WBC count after operation are the risk factors for DVT in the lower extremities in patients after hip or knee arthroplasty and hip fracture internal fixation.

Objective To evaluate the therapeutic effects,acute and late side-effects of cisplatin plus 5-fluorouracil (PF) schemed chronomodulated chemotherapy combined with concurrent intensitymodulated radiotherapy(IMRT) for nasopharyngeal carcinoma.Methods A total of 48 nasopharyngeal carcinoma patients treated with chronomodulated chemotherapy plus concurrent IMRT were retrospectively studied.The radiation doses prescribed to the gross target volume GTVnx of nasopharyngeal,to the positive neck lymphnodes GTVnd,to the clinical target volume CTV1,and to CTV2 were 73.92-77.88,69.96,60.06-66.00 and 50.96-56.00 Gy respectively.The Kaplan-Meier survival analysis was used to calculate the local-regional progression-free rate.The acute and late side-effects were graded according to RTOG radiation morbidity scoring criteria.Results The complete remission (CR) rate was 41.6％(20/48) ; the partial remission (PR) rate was 47.9％ (23/48) ; the stable disease (SD) rate was 4.2％(2/48) ; and the local tumor control rate was 89.6％.Most of the patients had grade 1 to 2 acute side effects and grade 0 to 1 late side-effects.No grade 4 acute and late toxicity was observed.1,2,4-year survival rates were 93.8％,79.2％ and 64.5％,respectively.The DVH analysis showed that IMRT improved the total dose and dose per-fraction to the target volume with considerable dose reduction of the normal structures at the same time.Conclusions PF chronomodulated chemotherapy plus concurrent intensity-modulated radiotherapy for NPC could improve therapeutic effects with satisfactory tolerance of the side effects.

Objective To assess the prevalance and distribution of pain in Parkinson' s disease (PD) patients, and to describe the relationship between pain and development of disease and its impact on the quality of life. Methods 113 PD patients were assessed with Visual Analog Scale (VAS), Brief Pain Inventory (BPI), Unified Parkinson' s Disease Rating Scale (UPDRS), Hoehn-Yahr Scale (H-Y), Hamilton Anxiety and Depression Scale (HRSD, HAMA) and Pittsburgh Sleep Quality Index (PSQI). Patients were divided into no pain group, PD-pain group and non-PD-pain group. PD-pain group was divided into PD-pain direct group and PD-pain indirect group. And statistical analysis was performed for each group. Results The incidence of PD-pain was 42. 5% (48/113). And compared with no pain group, PD-pain group had earlier age at onset of disease, longer duration, higher HAMA, HRSD, UPDRS and H-Y score, higher daily L-dopa dose, with statistical significance. Compared with non-PD pain group, the differences in the onset of age (57.4±9.6 vs 65.9±8.7, t= -2.596, P =0.012), HRSD(12. 9±7.9 vs 8.7±3.7, t =2.605, P=0.014) and VAS (61.6±25.9 vs 38.0 ± 30. 1, U = -2.290, P =0.022) were also statistically significant. BPI was different between PD-pain direct group and PD-pain indirect group except normal work and relations with other people. Conclusion Pain is frequent in Parkinsonian population. Most pain was chronic and related to PD (PD-pain). These patients always have earlier onset age and poorer quality of life.

Objective To evaluate the effects of reduced glutathione (GSH) on contractile and diastolic functions of the thoracic aorta of rats with obstructive jaundice.Methods Twenty-four adult male Sprague-Dawley rats,weighing 200-250 g,were randomly divided into 4 groups (n =6 each) using a random number table:sham operation group (group S),GSH group,bile duct ligation group (group BDL),and GSH + bile duct ligation group (group GSH + BDL).In GSH and GSH + BDL groups,GSH 300 mg/kg was infused via stomach everyday for 7 consecutive days,while the equal volume of normal saline was given in the other two groups.The common bile duct was ligated in the animals on 1 d after the end of intragastric administration in GSH and GSH + BDL groups.In GSH and GSH + BDL groups,after the model was established,GSH 300 mg/kg was infused via stomach everyday for 7 consecutive days,while the equal volume of normal saline was given in the other two groups.On 7th day after the model was extablished,blood samples were collected for determination of the levels of serum total bilirubin (TB),alanine aminotransferase (ALT) and aspartate aminotransferase (AST),tumor necrosis factor-alpha (TNF-α),interleukin-lβ (IL-1β) and 3-nitrotyrosine (3-NT),malondialdehyde (MDA),nitric oxide (NO) and GSH.The thoracic aortic rings were obtained and perfused with different concentrations of norepinephrine (NE),acetylcholine (Ach) and sodium nitroprusside (SNP).The maximum contraction and dilatation of aortic rings were recorded and the percentage was calculated.Some thoracic aortic rings were obtained again and perfused with different concentrations of NE after removal of the endothelium or after being perfused with L-NAME (nitricoxide synthase inhibitor).The maximum contraction of aortic rings was recorded and the percentage was calculated.Results Compared with group S,the serum levels of TB,ALT,AST,TNF-α,IL-1β,MDA,3-NT,NO and GSH were significantly increased in group BDL,and the serum levels of TB,ALT,AST,MDA,GSH and NO were increased in group BDL + GSH,the percentage of the maximum contraction amplitude of aortic rings in response to NE was decreased,and the percentage of the maximum dilatation amplitude of aortic rings in response to Ach and SNP were decreased in groups BDL and BDL + GSH,and no significant changes were found in the parameters mentioned above in group GSH.Compared with group BDL,the serum levels of TB,ALT,AST,TNF-α,IL-1β,MDA,3-NT and NO were significantly decreased,the level of GSH was increased,the percentage of the maximum contraction amplitude of aortic rings in response to NE was increased,the percentage of the maximum dilatation amplitude of aortic rings in response to Ach was increased,and no significant change was found in the percentage of the maximum dilatation amplitude of aortic rings in response to SNP in group BDL + GSH.Compared with the aortic rings from which the endothelium was removed or which were perfused with L-NAME in group BDL,no significant change was found in the percentage of the maximum contraction amplitude of aortic rings after removal of the endothelium or after being perfused with L-NAME in response to NE in group BDL + GSH.Conclusion GSH can improve the contractile and diastolic functions of thoracic aorta of rats with obstructive jaundice and this effect depends on the vascular endothelium.
