OBJECTIVEThis study compared two newborn Cytomegalovirus (CMV) IgG antibody screening ELISA kits and evaluated the detection effectiveness of Abnova kit.

METHODSCMV IgG antibodies were detected by both SeraQuest and Abnova kits from dried blood spot (DBS) samples of 488 newborn heel sticks. The detection abilities of these two kits were compared in different sample dilution concentrations. Relative detection effectiveness of the Abnova kit was defined by statistical method using the SeraQuest kit as a point of comparison.

RESULTCompared to the SeraQuest screening test kit, the Abnova kit revealed a sensitivity of 98.9%, specificity of 78.6%, positive predictive value of 99.3%, negative predictive value of 68.8%, and the coincidence rate for these two screening test kits at 98.3%. The consistency check of both kits based on interpretation of the kappa statistic was relatively good. For the Abnova kit, the "area under the ROC curve" was 0.887, which indicates moderate accuracy.

CONCLUSIONAbnova kit can be applied to newborn screening for congenital CMV infections. However, repeating the test for ambiguous results is suggested to increase the specificity and negative predictive value.

Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

Objective To investigated the effects of combined arsenic trioxide(ATO) and resveratrol(Res)on the viability of NB4 human leukemia cells. Methods NB4 human leukemia cell was used in this experiment.Cells were cultured in ATO (0,0.1875,0.3750,0.7500, 1.1250, 1.5000,2.2500,3.0000,5.0000 μmol/L) and Res (0, 1.5625,3.1250,6.2500, 12.5000, 18.7500,25.0000,37.5000,50.0000 μmol/L). Cell viabilities were measured by MTT in different treatment groups. Half inhibitory concentration(IC50) was calculated. The ratio of concentration of ATO and Res 1.5∶ 18,1.5∶ 25,1.5∶ 35 was added to cells, and the combination index(CI) was calculated. The level of ROS in control, ATO( 1.5000 μmol/L), Res(25.0000 μmol/L) and ATO(0.9000 μmol/L) + Res( 12.5000μmol/L) groups was measured by chemiluminescence assay. Results ①ATO( ≥0.7500 μmol/L) reduced the viability of NB4 cells in a concentration-dependent manner(P ＜ 0.05 ), and IC50 was (1.78 ± 0.11 )μmol/L. ②)Res (≥18.7500 μ mol/L) dose-dependently decreased the viability of NB4 cells (P ＜ 0.05 ), and IC50 was ( 18.71 ±0.18)μ mol/L. ③Combination of ATO and Res showed an antagonistic effect on NB4 cells viability. ④The ROS in Res group( 1670.55 ± 13.97) was significantly lower than that in control group(2345.88 ± 14.48,P ＜ 0.05). The ROS in ATO group (3092.42 ± 94.84) was significantly higher than that in control group(P ＜ 0.05). The ROS in ATO + Res group (1860.27 ± 15.99) was significantly lower than that in ATO group(P ＜ 0.05). Conclusions NB4 cell survival rate can be decreased by ATO and Res. The combination of arsenic trioxide and Res presents an antagonistic effect on NB4 cell viability, in part by reducing intracellular ROS formation.

The megakaryocyte and platelet lineage may be one of the major sites of human cytomegalovirus (HCMV) infection. However, whether HCMV aggravates apoptosis in normal megakaryocytes was not well investigated. Megakaryocytic cell line CHRF-288-11 and HCMV AD 169 strain were co-cultured in this study. PCR was used to detect the direct infection of the cells by HCMV IEA expression. The apoptotic cells were analyzed by morphologic observation, DNA ladder formation, annexin V/PI and PI assay with flow cytometry. The results showed that HCMV significantly inhibited the growth of CHRF cells in three different concentrations of viral infection groups (10(-3), 10(-2), 10(-1)). The viability levels in each infection groups were 77%, 73% and 68% respectively after incubation for 7 days, compared with 98% in the control group. Using annexin V/PI with flow cytometry, it was shown that the percentages of apoptotic cells viral infection in groups (10(-3), 10(-2), 10(-1)) were (21.3 +/- 2.49)%, (25.8 +/- 3.65)% and (31.4 +/- 3.91)% at 7 days after infection, while the control was (3.68 +/- 1.47)%. The apoptotic cells were further confirmed by morphologic observation and DNA ladder formation. Furthermore, PCR detection also showed the direct infection by identification of HCMV IEA expression in CHRF cells. This study suggested that HCMV could directly infect megakaryocytes and aggravated apoptosis in HCMV-infected megakaryocytes.

Objective To develop a multiplex sequence-specific PCR assay for simultaneous screening of 5 types of JAK2 mutations and investigate its clinical application value. Methods Multiplex sequence-specific PCR assay for simultaneous screening of JAK2 V617F, K539L (include 2 types of gene mutations), N542-E543del and E543-D544del mutations were developed. 115 patients with myeloproliferative diseases (MPD) including 61 polycythemia vera (PV) cases, 43 essential thrombocythemia (ET) cases and 11 primary myelofibrosis (MF) cases were analyzed. Results The assay can screen the 5 types of JAK2 mutations efficiently. The detection sensitivity is 1% for JAK2 V617F mutation and 0.1% for the other mutations. JAK2 V617F mutation and JAK2 exon12 mutation were detected in 56 and 3 of the 61 PV samples, respectively. 27 of the 43 ET samples and 6 of the 11 MF samples were JAK2 V617F positive, but no JAK2 exon12 mutation was found in both groups. The 3 cases carrying JAK2 exon12 mutation had the clinical feature of erythrocytosis and erythropoietin-independent erythroid colony formation but without apparent leukocytosis, thrombocytosis and splenectasis. Conclusion The assay can simultaneously screen 5 types of JAK2 mutations with high sensitivity and thus lead to an increased detection rate.

OBJECTIVETo explore the correlation between angiographically-defined coronary heart disease (CHD) and chronic periodontitis (CP).

METHODS277 cases with CHD (case group) and another 238 with no agiographic evidence of CHD (control group) were compared on their traditional cardiovascular risk factors, as: oral health status and probing depth, clinical attachment level, gingival recession, as well as number of missing teeth. Other related risk factors of CHD were included in a stepwise logistic regression analysis.

RESULTSData from univariate analysis showed that there was significant difference in CP, plasma triglyceride, high density lipoprotein cholesterol (HDL-C), fast glucose, white blood count, hypertension and smoking between patients with CHD and those with out CHD (P < 0.01 - 0.001). Multiple factorial logistic regression analysis showed that CP, hypertension, diabetes mellitus, HDL-C were strongly correlated with the incidence of CHD. Significant dosage-effective response was also found in the relationship between CP and CHD (P < 0.001). Further studies also suggested that the severity of CP paralleled the severity of CHD.

CONCLUSIONThe results indicated that CP might serve as an independent risk factor of CHD and significantly enhance the risk and severity of CHD. Our study suggested that the elimination of probable risk factors in oral cavity was indispensable during the process of the prevention of CHD in order to prevent acute coronary events.

OBJECTIVETo study the causes of orchiectomy in different age groups.

METHODSWe retrospectively reviewed the clinical data about 291 cases of orchiectomy performed between March 1993 and October 2014 and analyzed the causes of surgery and their distribution in different age groups.

RESULTSThe main causes of orchiectomy were testicular torsion (45.8%), cryptorchidism (32.5%) and testicular tumor (16.9%) in the patients aged 0-25 years, testicular tumor (42.4%), cryptorchidism (25.9%) and tuberculosis (10.6%) in those aged 26-50 years. Prostate cancer was the leading cause in those aged 51-75 years (77.6%) or older (84.0%)), and testicular tumor was another cause in the 51-75 years old men (10.2%). Prostate cancer, testicular tumor, cryptorchidism, and testicular torsion were the first four causes of orchiectomy between 1993 and 2009. From 2010 to 2014, however, testicular tumor rose to the top while prostate cancer dropped to the fourth place.

CONCLUSIONThe causes of orchiectomy vary in different age groups. The proportion of castration for prostate cancer patients significantly reduced in the past five years, which might be attributed to the improvement of comprehensive health care service.
