Objective To investigate the incidence of hearing disorder and analyse the high-risk factors with hearing injury in newborns with hyperbilirubinemia.Methods The newborns with hyperbilirubinemia who admitted to the department of neonate,were received the distortion product otoacoustic emission(DPOAE)test when they recovered from hyperbilirubinemia;those babies who didn′t pass the first test received screening again in 42 days after birth.Those babies who didn′t pass the second test received auditory brain stem response(ABR)test.Results Fifty-eight(33.2%)newborns didn′t pass the first DPOAE test among 235 newborns with hyperbilirubinemia;11(18.9%)infants didn′t pass the second DPOAE test among 58 infants;5 infants failed to pass the ABR test,the ratio of hea-ring disorder in newborns with hyperbilirubinemia was 2.13%;18(9.9%)newborns didn′t pass the first DPOAE test among 182 normal newborns,and those infants all passed the second DPOAE test.Conclusions Hyperbilirubinemia is high-risk population of hearing disorder.The congenital cytomegalovirus infection,neonatal septicemia and hemolytic disease of newborn are the high risk factors responsible for hearing disorder.All high risk newborns should recieve hearing examination regularly.

To evaluate soluble GM-CSF-Ralpha expression in patients with acute myeloid leukemia (AML) and its clinic significance, plasma concentration of solGM-Ralpha in de novo 66 patients with AML was detected by enzyme-linked immuno-sorbent assay, and the relationship between solGM-Ralpha levels and various clinical parameters was analyzed. The result showed that the levels of solGM-Ralpha in plasma of patients with AML were significantly higher than that in plasma of normal controls; the lowest level of solGM-Ralpha was found in plasma of patients with AML-M3 (3897.75 +/- 2651.43 pg/ml), the highest level of solGM-Ralpha was observed in plasma of patients with AML-M5 (9990.92 +/- 6325.43 pg/ml). Patients with high level of solGM-Ralpha were generally accompanied with a distinct clinical picture, including higher counts of white blood cell and myeloid precursors, as well as higher expression of CD34, CD95 and CD116 antigen. It is concluded that the high level of solGM-Ralpha in plasma of patients may suggest AML poor prognosis and play a role in pathogenesis of leukemia, the GM-CSF and its receptor solGM-Ralpha needs further study.

OBJECTIVETo compare the difference in clinical efficacy on lumber disc herniation (LDH) treated with Yaoyangguan (GV 3) between mild moxibustion under thermosensitive condition and that under non-thermo-sensitive condition.

METHODSFifty-seven LDH patients were selected as the study objects. Mild moxibustion at Yaoyangguan (GV 3) was applied for 45 min each time. Additionally, the conventional acupuncture was given, once a day, for 20 days. At the end of treatment, two groups were classified. A thermosensitive acupoint group (thermosensitive group) was composed of the cases with thermo-sensitization at Yaoyangguan (GV 3) and presenting for > or =4 times in the entire treatment. A non-thermosensitive acupoint group (tranquilization group) was composed of the cases without thermo-sensitization or the frequency of thermo-sensitization <4 times in the entire treatment. The modified Japanese orthopedics association scoring system (M-JOA) was adopted to observe the cases before and after treatment and 6 months after treatment in the two groups. The efficacy was compared between the two groups.

RESULTSAfter treatment and in 6 months after treatment, the score of M-JOA was apparently reduced as compared with that before treatment in the two groups (all P<0.05). The score reducing in the thermosensitization group was more obvious than that in the tranquilization group (both P<0.01). After treatment and in 6 months after treatment, the curative rate and remarkably effective rate were 89.7% (26/29) and 79.3% (23/29), which was better than 71.4% (20/28) and 60.7% (17/28, both P<0.05) in the tranquilization group separately.

CONCLUSIONMild moxibustion at acupoint under thermosensitive condition achieves the better short-term and long-term effects as compared with that under non-thermosensitive condition.

OBJECTIVES: To study the correlation of the expression of Lipin1 in visceral adipose tissue and Lipin2 in liver tissue with hepatic fat content in rats with intrauterine growth retardation (IUGR). METHODS: Pregnant rats were given a low-protein (10% protein) diet during pregnancy to establish a model of IUGR in neonatal rats. The pregnant rats in the control group were given a normal-protein (21% protein) diet during pregnancy. The neonatal rats were weighed and liver tissue was collected on day 1 and at weeks 3, 8, and 12 after birth, and visceral adipose tissue was collected at weeks 3, 8, and 12 after birth. The 3.0T ¹H-magnetic resonance spectroscopy was used to measure hepatic fat content at weeks 3, 8, and 12 after birth. Real-time PCR was used to measure mRNA expression levels of Lipin2 in liver tissue and Lipin1 in visceral adipose tissue. Western blot was used to measure protein levels of Lipin2 in liver tissue and Lipin1 in visceral adipose tissue. A Pearson correlation analysis was performed to investigate the correlation of mRNA and protein expression of Lipin with hepatic fat content. RESULTS: The IUGR group had significantly higher mRNA and protein expression levels of Lipin1 in visceral adipose tissue than the control group at weeks 3, 8, and 12 after birth (P<0.05). Compared with the control group, the IUGR group had significantly lower mRNA and protein expression levels of Lipin2 in liver tissue on day 1 after birth and significantly higher mRNA and protein expression levels of Lipin2 at weeks 1, 3, 8, and 12 after birth (P<0.05). At week 3 after birth, there was no significant difference in hepatic fat content between the IUGR and control groups (P>0.05), while at weeks 8 and 12 after birth, the IUGR group had a significantly higher hepatic fat content than the control group (P<0.05). The protein and mRNA expression levels of Lipin1 were positively correlated with hepatic fat content (r=0.628 and 0.521 respectively; P<0.05), and the protein and mRNA expression levels of Lipin2 were also positively correlated with hepatic fat content (r=0.601 and 0.524 respectively; P<0.05). CONCLUSIONS Upregulation of the mRNA and protein expression levels of Lipin1 in visceral adipose tissue and Lipin2 in liver tissue can increase hepatic fat content in rats with IUGR and may be associated with obesity in adulthood.

The aim of this study was to detect the expressions of transforming growth factor (TGFβ(1)), tumor necrosis factor alpha (TNFα) and leukemia inhibitory factor (LIF) in newly diagnosed patients with acute myeloid leukemia (AML) and investigate the association between serum levels of various cytokines and clinical outcomes. The levels of TGFβ1, TNFα and LIF in patient's plasma were detected by enzyme-linked immunosorbent assays (ELISA) and were compared with healthy controls; bone marrow cell morphology, immunology, cytogenetics examinations (MIC) were performed meanwhile. The results showed that levels of TGFβ1, TNFα and LIF were elevated in AML patients as compared with the controls (13.08±9.77 ng/ml, 10.67±15.11 pg/ml, 4.23±4.73 pg/ml vs 8.23±3.12 ng/ml, 5.86±3.05 pg/ml, 2.78±1.22 pg/ml) (p all<0.05). The three cytokines and MIC examination analysis indicated that level of LIF was abnormally elevated in M5 patients (7.14±6.62 pg/ml); TNFα was abnormally elevated in M4 and M3 patients especially M4; TGFβ1 level in M6 and M2 patients was higher than others. TGFβ1 plasma concentration in low-risk group the lowest (10.45±4.73 ng/ml), and that in middle risk group was the highest (16.13±13.76 ng/ml) (p<0.05); the levels of other two kinds of factors in the chromosome karyotype groups showed no significant difference. It is concluded that TGFβ1, TNFα and LIF expressions showed increased level in the untreated patients with de novo AML, the TGFβ1 level among which is associated with the prognosis of patients.

OBJECTIVEGanciclovir is a first-line drug for treatment of cytomegalovirus (CMV) infection. However, some ganciclovir treatment-related side-effects can be found. This study aimed to compare the efficacy and side effects of relatively low and high doses of ganciclovir in the treatment of neonatal congenital CMV infection.

METHODSOne hundred and sixty-seven neonates with congenital CMV infection were randomly assigned to high-dose (n=79) and low-dose ganciclovir groups (n=88). The high-dose ganciclovir group was injected with ganciclovir of 7.5 mg/kg in the inducement phase and of 10 mg/kg in the maintaining phase. The low-dose ganciclovir group was injected with ganciclovir of 5 mg/kg in the inducement and the maintaining phases. The efficacy and side effects were observed in the two groups.

RESULTSAfter treatment the clinical symptoms and signs were obviously improved in both groups. CMV-IgM became negative in 93.8% of neonates in the high-dose ganciclovir group and 93.1% of neonates in the low-dose ganciclovir group (P>0.05). CMV-DNA became negative in 80.8% of neonates in the high-dose ganciclovir group and in 86.7% in the low-dose ganciclovir group (P>0.05). The low-dose ganciclovir group had lower incidence of side effects than the high-dose ganciclovir group: vomiting 2.3% vs 11.4%; anemia 8.0% vs 20.3%; reduction of neutrophilic granulocytes 5.7% vs 16.5%; increase in platelet count 8.0% vs 18.9% (P<0.05).

CONCLUSIONSLow-dose ganciclovir has the same clinical efficacy to high-dose ganciclovir for treatment of neonatal congenital CMV infection, but fewer side effects occur in the low-dose group.

OBJECTIVETo evaluate the efficacy and safety of ganciclovir therapy for congenital cytomegalovirus (CMV) infection in newborn infants.

METHODSThe randomized controlled trials (RCTs) and quasi-RCTs on ganciclovir therapy for congenital CMV were reviewed in the following electronic databases: PubMed (January 1988 to January 2009), EMbase (January 1988 to January 2009), the Cochrane library (Issue 3, 2003 and Issue 1, 2009), the Chinese Journals Full-text Database (January 1994 to January 2009), the Chinese Biological Medical Disc (January 1994 to January 2009) and the Chinese Medical Current Contents (January 1994 to January 2009). Quality assessment, data extraction, and meta analysis were performed.

RESULTSTen papers were included. Meta analysis showed that the ganciclovir therapy increased the improvement rate (91.4% vs 34.0%; p<0.01) and led CMV infection indexes to become negative in more patients (87.6% vs 15.3%; p<0.01) and decreased incidence of hearing disturbance (4.7% vs 37.2%; p<0.01) as compared with the non-ganciclovir therapy control group. The incidence of the ganciclovir-therapy-related side effects was low.

CONCLUSIONSGanciclovir treatment may increase the improvement rate and the rate of CMV infection indexes becoming negative, and decrease incidence of hearing disturbance, with few side effects, in newborn infants with CMV infection. However the supporting evidence is not strong due to few trials and more high-quality research is needed.

Objective To evaluate the prevalence of depression,anxiety and suicide behavior in patients suffering from tuberculosis in Hangzhou and to explore their relationship with medication adherence. Methods Demographic characteristics,self-rating anxiety scale (SAS),the center for epidemiological studies -depression (CESD),social support rating scale (SSRS),suicide behavior information and the morisky medication adherence scale (MMAS)were investigated in 973 tuberculosis patients who were selected by systematic random sampling.Results The means of SAS and CESD were 39.71 ±8.30 and 14.16 ±10.77 respectively,which were both higher than the norms(P<0.01).Totally 102 (10.48%)patients had anxiety and 333 (34.22%)were depressed.Out of 973 patients,60 (6.17%)reported suicide ideation after tuberculosis diagnosis.The prevalence of non -adherence was 20.55%,which was defined with MMAS score above one and more.The non -adherence group had higher anxiety,depression and suicide ideation prevalence than the adherence group (15.50%vs.9.18%,46.50%vs.30.66%,11.00%vs.4.92%respectively,P<0.01).The mean score of SSRS,subjective support,objective support and utilization of support in the non-adherence group were 30.71 ±5.15,4.61 ±2.07,19.74 ±4.55 and 6.34 ±1.93 respectively,which were 34.06 ±7.39,6.62 ± 2.27,20.67 ±5.27 and 6.77 ±2.23 in the adherence group respectively.SSRS and its three dimension scores were significantly lower in the non-adherence group than that in the adherence group (P<0.01).Conclusion These findings show a quite serious situation of psychological problems of tuberculosis patients in Hangzhou and suggest psychological intervention should be included in adherence intervention.

Purpose::Vibrio vulnificus ( V. Vulnificus) infection is characterized by rapid onset, aggressive progression, and challenging treatment. Bacterial resistance poses a significant challenge for clinical anti-infection treatment and is thus the subject of research. Enhancing host infection tolerance represents a novel infection prevention strategy to improve patient survival. Our team initially identified cytochrome P4501A1 (CYP1A1) as an important target owing to its negative modulation of the body's infection tolerance. This study explored the superior effects of the CYP1A1 inhibitor bergamottin compared to antibiotic combination therapy on the survival of mice infected with multidrug-resistant V. Vulnificus and the protection of their vital organs. Methods::An increasing concentration gradient method was used to induce multidrug-resistant V. Vulnificus development. We established a lethal infection model in C57BL/6J male mice and evaluated the effect of bergamottin on mouse survival. A mild infection model was established in C57BL/6J male mice, and the serum levels of creatinine, urea nitrogen, aspartate aminotransferase, and alanine aminotransferase were determined using enzyme-linked immunosorbent assay to evaluate the effect of bergamottin on liver and kidney function. The morphological changes induced in the presence of bergamottin in mouse organs were evaluated by hematoxylin and eosin staining of liver and kidney tissues. The bacterial growth curve and organ load determination were used to evaluate whether bergamottin has a direct antibacterial effect on multidrug-resistant V. Vulnificus. Quantification of inflammatory factors in serum by enzyme-linked immunosorbent assay and the expression levels of inflammatory factors in liver and kidney tissues by real-time quantitative polymerase chain reaction were performed to evaluate the effect of bergamottin on inflammatory factor levels. Western blot analysis of IκBα, phosphorylated IκBα, p65, and phosphorylated p65 protein expression in liver and kidney tissues and in human hepatocellular carcinomas-2 and human kidney-2 cell lines was used to evaluate the effect of bergamottin on the nuclear factor kappa-B signaling pathway. One-way ANOVA and Kaplan-Meier analysis were used for statistical analysis. Results::In mice infected with multidrug-resistant V. Vulnificus, bergamottin prolonged survival ( p = 0.014), reduced the serum creatinine ( p = 0.002), urea nitrogen ( p = 0.030), aspartate aminotransferase ( p = 0.029), and alanine aminotransferase ( p = 0.003) levels, and protected the cellular morphology of liver and kidney tissues. Bergamottin inhibited interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α expression in serum (IL-1β: p = 0.010, IL-6: p = 0.029, TNF-α: p = 0.025) and inhibited the protein expression of the inflammatory factors IL-1β, IL-6, TNF-α in liver (IL-1β: p = 0.010, IL-6: p = 0.011, TNF-α: p = 0.037) and kidney (IL-1β: p = 0.016, IL-6: p = 0.011, TNF-α: p = 0.008) tissues. Bergamottin did not affect the proliferation of multidrug-resistant V. Vulnificus or the bacterial load in the mouse peritoneal lavage fluid ( p = 0.225), liver ( p = 0.186), or kidney ( p = 0.637). Conclusion::Bergamottin enhances the tolerance of mice to multidrug-resistant V. Vulnificus infection. This study can serve as a reference and guide the development of novel clinical treatment strategies for V. Vulnificus.

OBJECTIVETo further understand the association of hantavirus (HV) harbored and transmitted in wild brown rats.

METHODSRattus norvegicus (n = 570) were trapped in 10 sites in Beijing. RT-PCR was used to test rodent lung samples for hantavirus infection. Unconditional multivariate logistic regression analysis was performed, with PCR positive as the dependent variable and the characteristics of Rattus norvegicus population as independent variables.

RESULTSThe overall HV prevalence in Rattus norvegicus was 9.1% (52/570). Significant association between HV infection in Rattus norvegicus and some biological characteristics of host population was observed. Adult Rattus norvegicus had a higher HV prevalence than juveniles. Males in the reproduction periods and rats with wounds were more likely to be infected with HV than others.

CONCLUSIONIt was further confirmed that there existed parallel transmission of HV in Rattus norvegicus hosts. Aggression might be the primary mode of HV transmission among male Rattus norvegicus.
