Objective To investigate early renal damage of chronic hepatitis B (CHB) patients and the risk factors related to their renal function. Methods CHB patients who visited the second people’s hospital but did not receive systemic treatment were enrolled in our study. Those who visited for general check-up with no hepatic findings during the same period were selected as control group. Glomerular filtration rate (GFR) of all the participants were estimated by simplified MDRD equation and CKD-EPI equation (designated as M-eGFR and C-eGFR respectively). Influence factors of eGFR were statistically analyzed. Results In the total 528 cases in CHB group, 88 (16.67%) and 62 (11.74%) suffered declined M-eGFR and C-eGFR respectively. By contrast, 10 (8.77%) and 6 (5.26%) cases in the total 114 cases in control group present declined M-eGFR and C-eGFR ac?cordingly. Percentages of renal function impairment, estimated by both M-eGFR and C-eGFR, were higher in the CHB group than those in control group. The difference was statistically significant (χ2=4.518, P<0.05;χ2=4.156, P<0.05). Multiple linear regression analysis indicated that age, HBsAg and body mass index (BMI) were risk factors of M-eGFR while age, HBsAg, gender and serum albumin were risk factors of C-eGFR. On the other hand, HBV-DNA and HBeAg were not risk factors for M-eGFR or C-eGFR. Conclusion HBV infection can lead to early renal damage. Age and HBsAg are main risk factors of renal function impairment. Therefore, renal function should be scrutinized in CHB patients.

Objective To analyze the differential proteomics of ASMC stimulated by wild IL-13 and mutant IL-13 and to investigate the relations of protein profiles of ASMC to asthma and possible targets for the treatment of bronchial asthma.Methods The total proteins of ASMC stimulated by wild IL-13 and mutant IL-13 were separated by immobilized pH gradient(IPG)-based 2-DE and the differentially expressed protein spots were identified by matrix assisted laser desorption-time of flight mass spectrometry(MALDI-TOF-MS). Results The 2-DE detected approximately(840?21)spots on wild IL-13 samples and(892?17)spots on mutant IL-13 samples(n=3)and(685?19)spots matched.Six significantly differential proteins were subjected to MALDI-TOF-MS analysis and three of them were identified as stathmin 1,Ribosomal protein p~0 and NADH dehydrogenase.Conclusions ASMCs stimulated by wild IL-13 and mutant IL-13 present different proteomic profiles that may shed some light on the mechanism for the asthma causing effect of wild IL-13 and mutant IL-13.

The relationship between serum uric acid(SUA) and hypertension was investigated and the interactions of SUA with metabolic risk factors was assessed. Blood pressure and biomarkers features were evaluated for all the8 415 individuals from a community-based health examination survey in Xuzhou, and the statistical analysis was made. Raised blood pressure was associated with increased SUA concentration(P<0.01). Age and high density lipoprotein cholesterol(HDL-C) significantly interacted with SUA(P for interaction=0.012 and 0.001, respectively). There is significant association between SUA and hypertension, which may be affected by age and HDL-C levels.

AlM: To investigate the effect of endocapsular phacoemulsification cataract extraction and intraocular lens (lOL) implantation with a 1. 8mm or 3. 0mm clear corneal incision on total root mean square ( RMS ) value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film.
METHODS:ln a prospective study, 156 age- related patients ( 196 eyes ) were randomly distributed into two groups. 1. 8mm-group comprised 94 eyes that had a silicone lOL inserted through a 1. 8mm sutureless clear corneal incision, while, 3. 0mm- group comprised 102 eyes through a 3. 0mm clear corneal incision. Postoperatively, the changes in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film at 1wk, 1 and 3mo were determined respectively.
RESULTS:ln both groups, postoperatively at 1wk,there were statistically significant differences ( P<0. 05 ) in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film, while, there were statistically minimal differences ( P< 0. 05 ) between 1. 8mm-group and 3. 0mm-group at 1mo, but were not statistically significantly different ( P > 0. 05 ) between two groups at 3mo postoperative.
CONCLUSlON:This study confirms that incision size has strong impact on the corneal higher-order aberrations, especially, 3. 0mm incision caused significant differences in the total RMS value of cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film compared with 1. 8mm micro-incision, therefore, micro-incision is very beneficial for clinical use in phacoemulsification.

OBJECTIVETo evaluate the application of shear wave elastography (SWE) combined with transition zone biopsy in the detection of prostate cancer (PCa).
METHODSA total of 489 patients with suspected PCa underwent transrectal ultrasonography (TRUS) and SWE-guided prostatic biopsy. We evaluated the role of SWE combined with transition zone biopsy in promoting the detection rate in comparison with the results of biopsy pathology.
RESULTSThe pathological results confirmed 221 malignant and 268 benign cases. Based on systematic biopsy, SWE combined with transition zone biopsy achieved a detection rate of 45. 19% , significantly higher than that of systematic biopsy alone (33.13%) (P < 0.05). The diagnostic sensitivity, specificity, and accuracy of SWE were significantly better than those of TRUS (P < 0.05). The mean elasticity (Emean) of SWE was remarkably higher for malignant than for benign lesions ([40.1 ± 9.5] vs [21.6 ± 8.3] kPa, P < 0.05). With 28.5 kPa as the threshold of the Emean value, the area under the ROC curve was 0. 899, and the diagnostic sensitivity and specificity were 88.71% and 86.23%, respectively.
CONCLUSIONSWE combined with transition zone biopsy could significantly improve the detection rate of prostate cancer.

Objective To observe the expression of cyclooxygenase(COX)-2 in different malignancy astrocytoma by immunohistochemistry,so as to judge the invasive action of COX-2 in astrocytoma.Methods A total of 55 cases with astrocytoma underwent 63 times operation including 8 recurrent cases were selected,and 9 cases with severe brain injury who needed decompression surgery were selected as control group.The astrocytoma tissues and decompression surgery to remove tissues removed immediately fixed in 10% formalin buffer solution.The expression of COX-2 was determined by immunohistochemistry.Results The positive expression rate of COX-2 in astrocytoma tissues was higher than that in decompression surgery to remove tissues[69.84% (44/63) vs.1/9],and there was significant difference (x2 =11.589,P < 0.01).The positive expression rate of COX-2 in recurrent astrocytoma tissues was higher than that in primmy astrocytoma tissues [8/8 vs.65.45% (36/55)],and there was significant difference (x2 =3.957,P < 0.05).With increased astrocytoma malignancy,the positive expression rate of COX-2 also increased,and there was significant difference (P < 0.05).Conclusion COX-2 may have some relationship with the invasion of astrocytoma,leading to increase tumor grade,and relapse.

Objective To investigate the mechanisms modulating the functions of dendritic cells (DCs) and suppressing the activation and proliferation of T cells by transforming growth factor-β (TGF-β).Methods Mouse splenic DCs were purified with CD11c+ immunomagnetic beads and the purity of isolated DCs were detected by flow cytometry.Gene chip was used to detect gene expression in DCs after stimulation with TGF-β, and then real-time PCR was performed to analyze the differentially expressed genes in microarray at mRNA level.The activation and proliferation of CD4+ T cells which were co-cultured with DCs after stimulation with TGF-β were detected by flow cytometry.Results The purity of DCs reached over 95% after isolation.TGF-β down-regulated the expression of cell surface markers CD53, CD69, CD33, CD74 and CD93 on DCs;decreased the expression of chemokines Ccl3, Ccl5, Ccl9, Ccl6, Ccl17, Cxcl10, Ccl22, Ccl4, Ccr7, Ccl2, Cxcl9 and Ccl7;inhibited the expression of inflammatory cytokines IL-2ra, IL-12rb2, IL-15ra, IL-1b and IL-15.Moreover, the DCs-mediated activation and proliferation of CD4+ T cells were suppressed by TGF-β.Conclusion TGF-β inhibits the DCs-mediated activation and proliferation of CD4+ T cells by suppressing the expression of surface markers on DCs and down-regulating the expression of chemokines and inflammatory cytokines.
