Purpose: the study aimed to compare the quality of life (QOL) and radiotherapy complications among Chinese nasopharyngeal carcinoma (NPC) patients at different 3-dimensional conformal radiotherapy (3DCRT) stages adjusting for other variables. Methods: 511 NPC patients at different 3DCRT stages were enrolled. They were interviewed regarding SF-36, complications and socio-demographic variables and cancer- or treatment-related variables. Analysis of covariance (ANCOVA) based on SF-36, complications scores as dependent variables, 3DCRT stages as independent variables, and other variables as covariate were established. Results: The influencing factors of PCS included 3DCRT stages and age group. The influencing factors of MCS included 3DCRT stages and income. Most QOL scores of NPC patients were significantly associated with 3DCRT stage, after accounting for other variables. QOL scores of the patients receiving 3DCRT were the lowest, QOL scores of people after 3DCRT gradually increased. PCS scores of people greater than 5 years after 3DCRT was improved to or even better than the level before 3DCRT. The complications with significantly different scores of patients at different 3DCRT status included xerostomia, throat ache, hypogeusia, caries, hearing loss, snuffles. Conclusions: Clinicians should pay more attention to older NPC patients and patients with lower income. When patients receive 3DCRT, measures should be taken to reduce radiation injury to improve the patients' QOL.

The pigment gland is an important character of the Gossypium plant. With the aim of identifying genes involved in pigment gland morphogenesis in cotton, gene expression during pigment gland morphogenesis in Chuan 2802, which is glanded both in seed and plant, and a glandless line N5 was profiled using Affymetrix Cotton microarray. The results showed that there were 564 differentially expressed genes greater than twofold during gland morphogenesis. About 60.2% of these genes shares similarity with known genes on GenBank and about 39.8% with no functional description in the database. These described genes may play roles in defense response, response to oxidative stress, peroxidase activity, and the other metabolic pathways. The KEGG Orthology-Based Annotation System indicated that these above twofold expressed genes involved seven biochemical pathways on KEGG. These findings suggest that a complicated regulation is associated with pigment gland morphogenesis and the associated defense response including gossypol biosynthesis in cotton.

Background: To determine the frequency of chronic kidney disease (CKD) and its associated risk factors in Chinese type 2 diabetic patients, we conducted a cross-sectional study in Nanjing, China, in the period between January 2008 and December 2009. Methods: Patients with type 2 diabetes under the care by Jiangsu Province Official Hospital, Nanjing, China were invited for assessment. CKD was defined as the presence of albuminuria or estimated glomerular filtration rate <60 mL/min/1.73 m2. Albuminuria was defined as urinary albumin-to-creatinine ratio ≥30 mg/g. Results: We recruited 1,521 urban Chinese patients with type 2 diabetes (mean age, 63.9±12.0 years). The frequency of CKD and albuminuria was 31.0% and 28.9%, respectively. After adjusted by age and sex, hypertension, anemia and duration of diabetes were significantly associated with CKD with odds ratio (95% confidence interval) being 1.93 (1.28 to 2.93), 1.70 (1.09 to 2.64), and 1.03 (1.00 to 1.06), respectively. Conclusion: In conclusion, CKD was common in the urban Nanjing Chinese with type 2 diabetes. Strategies to prevent or delay progression of kidney disease in diabetes should be carried out at the early disease course of type 2 diabetes.

Background/Aims: The application of glycated hemoglobin (HbA1c) for the diagnosis of diabetes is currently under extensive discussion. In this study, we explored the validity of using HbA1c as a screening and diagnostic test in Chinese subjects recruited in Nanjing, China. Methods: In total, 497 subjects (361 men and 136 women) with fasting plasma glucose (PG) ≥ 5.6 mmol/L were recruited to undergo the oral glucose tolerance test (OGTT) and HbA1c test. Plasma lipid, uric acid, and blood pressure were also measured. Results: Using a receiver operating characteristic curve, the optimal cutoff point of HbA1c related to diabetes diagnosed by the OGTT was 6.3%, with a sensitivity and specificity of 79.6% and 82.2%, respectively, and the area under the curve was 0.87 (95% confidence interval, 0.83 to 0.92). A HbA1c level of 6.5% had a sensitivity and specificity of 62.7% and 93.5%, respectively. When comparing the HbA1c ≥ 6.5% or OGTT methods for diagnosing diabetes, the former group had significantly higher HbA1c levels and lower levels of fasting and 2-hour PG than the latter group. No significant difference was observed in the other metabolism indexes between the two groups. Conclusions: Our results suggest that HbA1c ≥ 6.5% has reasonably good specificity for diagnosing diabetes in Chinese subjects, which is in concordance with the American Diabetes Association recommendations.

Two new anthraquinones, melrubiellin C (1) andmelrubiellin D (2), were isolated from the aerial parts of Melandriumfirmum Rohrbach, together with eight known compounds(3–10). The structures of these compounds wereelucidated using 1Dand 2DNMR(COSY,HMQC,HMBCandNOESY) experiments. All isolated compounds were tested fortheir cytotoxicity against NCI-H460, Hep G2, MKN-28 andA-549 cells.Of these 10 compounds,1 and 2 exhibitedmoderatecytotoxicity with IC50 values ranging from 9.54 to 32.41 lM.

Effects of osmolytes on the refolding of recombinant <i>Pelodiscus sinensis</i> brain-type creatine kinase

<P><B>Abstract</B></P> <P>The protective effects of osmolytes on the renaturation of <I>Pelodiscus sinensis</I> brain-type creatine kinase (P-CKB) were determined in this study. The P-CKB gene was cloned and was heterologously expressed in <I>Escherichia coli</I> BL21 (DE3). The purified recombinant protein was subjected to 6 M urea denaturation and further applied with six different osmolytes (glycine, proline, sorbitol, DMSO, betaine, and trehalose). Our results demonstrated that the addition of glycine or DMSO could contribute toward the reactivation of unfolded P-CKB and prevent aggregation. Interestingly, 25 mM glycine was found to be the best concentration to reactivate denatured P-CKB, while high-concentration glycine led to the opposite effect as monitored by a red shift in the intrinsic fluorescence spectra and the aggregation of protein, which probably could be attributed to an additional inactive protein complex that formed during the fast refolding reaction. Docking simulation results showed the osmolyte docking energies to be relatively low and clustering groups were spread on the surface of P-CKB, indicating that osmolytes directly protected the surface of P-CKB. The results in this study could provide a better understanding of structural and functional changes in P-CKB during refolding in addition to the role of osmolytes in heterothermic animals.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Osmolytes protects the activity of <I>Pelodiscus sinensis</I> brain-type creatine kinase (P-CKB). </LI> <LI> The addition of glycine or DMSO could contribute the reactivation of P-CKB. </LI> <LI> Glycine or DMSO could prevent aggregation. </LI> <LI> Docking simulation results showed that osmolytes directly protected the surface of P-CKB. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
