Objective To explore the relationship between Arg913Gln(G→A) polymorphism of solute carrier family 12 member 3 (SLC12A3) gene and diabetic nephropathy (DN) in type 2 diabetes mellitus (T2DM) in Han population of Shanghai. Methods Two hundred and fifty-eight Han ethnic people in Shanghai with T2DM (T2DM group) were divided into non-DN group (DN0 group, n=95) and DN group (n=163) according to 24 h urine albumin excretion rate (AER), and those in DN group were subdivided into microalbuminuria group (DN1 group, n=95) and macroalbuminuria group (DN2 group, n=68). Besides, 82 people with normal results of oral glucose tolerance test (OGTT), without diabetes mellitus and nephropathy were served as controls. PCR-sequencing was used to detect the genotypes of Arg913Gln polymorphism of SLC12A3 gene. Genotypic and allelic frequencies and clinical characteristics were compared among groups. Results Three genotypes (GG, GA and AA) were detected. The frequencies of GA+AA genotype and A allele in T2DM group were higher than those in control group, while there was no significant difference between groups (P>0.05). There was no significant difference in genotypic or allelic frequencies among subgroups of T2DM group (P>0.05). The level of triglyeeride (TG), AER, level of fasting insulin (FINS) and HOMA-IR in patients with GA+AA genotype were significantly higher than those in patients with GG genotype in T2DM group (P<0.05). Conclusion Arg913Gln(G→A) polymorphism of SLC12A3 gene is not significantly associated with T2DM and DN in Han population of Shanghai. The AER of people with GA+AA genotype is significantly higher than that with GG genotype. Arg913Gln (G→A) polymorphism of SLC12A3 gene may predict the risk of increase of albuminuria in patients with T2DM in Han population of Shanghai.

AIM:To explore efficacy of the different kinds of artificial tears treatment in patients with xerophthalmia after phacoemulsification combined with intraocular lens implantation.METHODS:Totally 280 patients (280 eyes) with xerophthalmia after operation in our hospital from January 2015 to June 2016 were selected.According to the different treatment methods, they were divided into control group (n=70;treated with tobramycin and dexamethasone eye ointment 3 times per day for 1wk, levofloxacin eye drops 3 times per day for 1wk, pranoprofen eye drops 4 times per day for 1mo), polyacrylic acid group (n=70;besides the treatment of control group, polyacrylic acid was used 4 times per for 1mo), polyethylene glycol group(n=70;besides the treatment of control group, polyethylene glycol was used 4 times per for 1mo) and sodium hyaluronate group (n=70;besides the treatment of control group, sodium hyaluronate was used 4 times per for 1mo).The tear film break up time (BUT), Schirmer Ⅰ test (SⅠt), symptoms of dry eye and corneal staining in four groups were observed.RESULTS:(1) BUT:The BUT of the four groups significantly increased after treatment(P<0.05);that of polyacrylic acid group, polyethylene glycol group, and sodium hyaluronate group was different compared with control group(P<0.05);the BUT in sodium hyaluronate group was significantly higher than the other groups after 2wk of treatment(P<0.05).(2) SⅠt:SⅠt of the four groups significant increased after treatment(P<0.05);that of polyacrylic acid group, polyethylene glycol group, and sodium hyaluronate group was different compared with control group(P<0.05);and the SⅠt in sodium hyaluronate group was significantly higher than other groups (P<0.05).(3) Xeroma score:the scores of dry eye significantly decreased after treatment in the four groups(P<0.05);that of polyacrylic acid group, polyethylene glycol group, and sodium hyaluronate group was different compared with control group(P<0.05);and the scores of the sodium hyaluronate group after 3wk was significantly lower compared with other groups(P<0.05).(4) Corneal staining score:the scores significantly decreased after treatment in the four groups(P<0.05);at 1 and 2wk after treatment the corneal staining score had not statistically different among the four groups (P>0.05);sodium hyaluronate group was significant lower than other groups in corneal staining score at 3wk and 1mo after treatment(P<0.05).CONCLUSION:Artificial tears in the treatment of xerophthalmia after cataract phacoemulsification combined with intraocular lens implantation has better clinical efficacy, which contains sodium hyaluronate may be the better than others.

The dynamic expression of cytokines and phenotypes during the differentiation process of dendritic cell precursors (pre-DCs) to mature dendritic cells (DCs) was investigated,and the effects of inflammatory stimulation with lipopolysaccharide (LPS) on DCs differentiation were understood.The differentiation of bone marrow cells isolated from Balb/c mice was induced to DCs in an 8-day cell culture system with RPMI-1640 complete culture medium containing 10％ FBS,20 ng/mL recombinant mouse granulocyte-macrophage colony-stimulating factor (rmGM-CSF) and 10 ng/mL recombinant mouse interleukin-4 (rmIL-4).On the day 3,6 and 7 after culture,DCs were divided into non-LPS group and LPS group,given 500 ng/mL LPS for 24 h stimulation and no stimulation respectively.The expression levels of CD 1 l c+,MHC-Ⅱ +,CD40+,CD80+ and CD86+ were detected by flow cytometry,and those of IL-2,IL-4,IL-10,IL-12 p70 and IFN-γ in the supernatant by ELISA.On the day 3 and 6 after culture,the expression of IL-2,IL-4,IL-10 and IFN-γ in DCs showed no significant differences between non-LPS group and LPS group,whereas the differences were significant at day 7.The expression levels of cytokines (for IL-2,IL-4,IL-10,IFN-γ and IL-12 p70:152.86±6.91,778.33±8.35,44.55±2.54,5.8.26±1.09 and 2423.00±57.21 pg/mL respectively) in LPS group were higher than those in non-LPS group,especially IL-12 p70 increased obviously at day 7.It was concluded that during the differentiation process of pre-DCs to mature DCs,LPS stimulates DCs producing large amounts of IL-12 p70 and Thl-type cytokines as compared with Th2-type cytokines,and day 7 may be a key time-point for DCs polarization.

OBJECTIVETo clarify whether neonatal jaundice may cause myocardial damage to term infants with normal birth weight (BW).

METHODSTotally 178 term neonates admitted during March, 2004 to December, 2010 with normal BW were enrolled. Infants with antenatal or neonatal asphyxia, temperature abnormality, septicemia, antenatal viral infection, congenital dysmorphia, congenital heart disease, 21-trisomy, and polycythemia were excluded. There was no maternal complications during the pregnancy. Serum total bilirubin (TB), creatine kinase (CK), MB isoenzymes of creatine kinase (CK-MB), and cardiac troponin-I (cTnI) were measured. Patients with transcutaneous bilirubin level (TcB) ≥ 342 µmol/L (20 mg/dl) were in Group A (n = 32), and those with TcB below phototherapy level at matched time point were in Group B (n = 25). ECG, for correct Q-T intervals (QTc) and correct QT intervals dispersion (QTcd), and ECHO, for left ventricular ejection fraction (EF), the ratio of the peak velocity of early stage and advanced stage of diastolic phase at the mitral orifice (E/A), were applied to patients in Group A and B. SPSS 13.0 software was used for the data analysis. The coefficients of correlation among age in hours on admission (hr), TB, CK, CK-MB, CK-MB/CK, and cTnI were studied by multiple and partial correlation analysis. Data in Group A and B were compared by independent-samples Mann-Whitney U test (nonparametric method) or Student t-test.

RESULTSWhen the data were analyzed by multiple correlation, there were significant correlation between TB and cTnI, CK-MB, respectively (r = 0.212, -0.161, respectively, all P < 0.05). But, when the data were analyzed by partial correlation, there was no correlation between TB and cTnI, CK-MB, respectively (r' = 0.112, -0.112, respectively, all P > 0.05), negative correlation between hr and TB, cTnI, respectively (r' = -0.490, P = 0.000; r' = -0.162, P = 0.032). There was no significant difference in CK (Z = -1.384, P = 0.166), CK-MB (Z = -0.821, P = 0.412), cTnI (Z = -1.159, P = 0.246), QTc (t = 1.146, P = 0.257), QTcd (t = 1.342, P = 0.185), EF (t = 1.558, P = 0.125), E/A (t = -0.640, P = 0.525) between group A and B. There was significant difference in CK-MB/CK (Z = -3.187, P = 0.001) between group A and B with a lower value in group A [0.075 (0.032 - 0.102)] comparing to that in group B [0.160 (0.073 - 0.284)].

CONCLUSIONThere is no sufficient evidence to support the hypothesis that neonatal jaundice may induce myocardial damage in normal birth weight term infants.

To investigate the eletrophysiological effect of rat adrenomedullin (rADM) on barosensitive neurons in the rostral ventrolateral medulla (rVLM) and its potential mechanisms, the extracellular recording and multi-barrel iontophoresis methods were used. Of the 29 barosensitive neurons in the rVLM, 20 neurons demonstrated excitatory response to iontophoretically applied rADM and increased the firing rate from (10.8 +/- 2.7) spikes/s to (14.6 +/- 3.6), (19.8 +/- 4.7) and (31.9 +/- 6.4) spikes/s (P<0.05, n=20) at the current of 30, 60 and 90 nA, respectively. Application of human adrenomedullin (22-52) [hADM (22-52)], a specific antagonist of rADM receptor, distinctly attenuated the augmentation of firing rate induced by rADMjthe firing rate was increased by 15.4% [(11.4 +/- 2.5) spikes/s, P<0.05, n=10]. Another antagonist, human calcitonin gene-related peptide (8-37) [hCGRP (8-37)] had no significant effect on rADM-induced excitation. Other 23 barosensitive neurons were recorded to test the influence of nitric oxide synthase (NOS) inhibitors on the excitatory effect of rADM. In 10 neurons, 7-NiNa (neuronal NOS inhibitor) decreased the firing rate from (10.1 +/- 3.5) spikes/s to (7.5 +/- 2.5), (5.3 +/- 2.1) and (3.1 +/- 1.4) spikes/s (P<0.05, n=10) at the current of 10, 20 and 40 nA, respectively. The excitatory effect of rADM (60 nA, 30 s) during 7-NiNa application was nearly eliminated and the magnitude of firing rate was increased only by 17% of the basal level (6.2 +/- 1.9) spikes/s (P<0.05, n=7). While aminoguanidine (AG, iNOS inhibitor) increased the firing rate at the resting level from (11.5 +/- 5.1) spikes/s to (17.8 +/- 5.6), (22.5 +/- 6.3) and (29.1 +/- 6.4) spikes/s (P<0.05, n=8) at the current of 10, 20 and 40 nA in 8 barosensitive neurons, respectively. When rADM (60 nA, 30 s) was delivered during AG iontophoresis period, the firing rate significantly increased by 60% of the basal level [(22.5 +/- 6.3) spikes/s, n=5]. These results indicate that rADM activates the barosensitive neurons in the rVLM directly and acts as a cardiovascular regulator, and that this function might be mediated by its specific receptor. NO, mainly neuronal NOS-originated might be involved in the excitatory effect of rADM in the rVLM.
