Objective To investigate the epidemiologic and clinical features of human immunodeficiency virus (HIV)/hepatitis B virus (HBV)co-infected patients.Methods Patients who confirmed with HIV infection and received highly active anti-retroviral therapy (HAART)at Guangzhou Eighth People′s Hospital were enrolled.HIV/HBV co-infected patients and HIV mono-infected patients were screened and their epidemiological and clinical features were analyzed before HAART.Comparison of the levels of alanine transaminase (ALT),aspartate transaminase (AST),CD4 + T lymphocyte and HIV RNA between the two groups were conducted.The data were statistically analyzed by chi-square test and nonparametric test.Results One hundred and sixty-five out of 1 218 (13.5 %)patients were hepatitis B surface antigen positive.The median ALT and AST levels of HIV mono-infected patients were 29 U/L and 34 U/L respectively,which were both higher than HIV/HBV co-infected patients (22 U/L and 25 U/L, respectively)(Z = - 4.270 and Z = - 5 .780,respectively,both P = 0.000 ).The median CD4 + T lymphocyte count of HIV/HBV co-infected patients was significantly lower than that of HIV mono-infected patients (Z = -2.980,P =0.003 ).The CD4 + T lymphocyte count was lower in hepatitis B e antigen (HBeAg)positive patients than HBeAg negative patients (Z =-2.660,P =0.008).The median CD4 + T lymphocyte count in patients with HBV DNA≥5 lg copy/mL was significantly lower than those with HBV DNA<5 lg copy/mL (Z = -2.311 ,P =0.021 ).The proportions of positive HBV DNA, HBV DNA≥5 lg copy/mL,abnormal ALT and AST in 54 patiens with CD4 + T lymphocyte counts <50/μL were 81 .5 %,66.7%,44.4% and 53.7%,respectively.All were significantly higher than patients with CD4 + T lymphocyte count≥50/μL(χ2 =6.159,P =0.046 ;χ2 =6.618,P =0.037 ;χ2 =7.144,P =0.028 andχ2 =9.586,P =0.008,respectively).Conclusions The prevalence of HBV/HIV co-infection is high in this study.The CD4 + T lymphocyte counts in HIV/HBV co-infected patients are lower,especially in patients with HBeAg positive and high HBV DNA level.The CD4 + T lymphocyte counts are associated with HBV DNA replication levels.

Objective To investigate the relationship between chest radiographic changes and clinical manifestations in patients with scrub typhus in Guangdong area.MethodsA total of 148 cases of scrub typhus admitted to First Affiliated Hospital of Ji′nan University,Guangzhou Eighth People′s Hospital and the Second People′s Hospital of Yuebei between 1999 and 2010 was retrospectively reviewed.The patients were divided into two groups based on the findings of the chest X-rays (with or without radiographic abnormalities).Furthermore,the clinical characteristics and prognosis in two groups were compared.The statistical analysis was done using t test,chi-square test or Fisher′s exact test.ResultsChest X-rays showed abnormalities in 66 (44.6％) cases,and the chest X-ray features were diverse.The incidences of cough,severe thrombocytopenia,hypoalbuminemia,shock,acute respiratory failure,jaundice and acute renal failure were all significantly increased in group of patients with chest X-rays abnormalities compared with the other group of patients without chest X-rays abnormalities (χ2 =18.193,6.872,17.138,5.608,4.318,7.982 and 7.932,respectively; all P＜0.05).The hospitalization day was longer in patients with chest X-rays abnormalities compared with the patients without chest X-rays abnormalities,but there was no statistical difference [(11.7±7.1)d vs (9.9±5.0)d,t=1.717; P=0.088)],while the mortality was higher(6.1 ％ vs 0; Fisher′s exact test,P =0.038).Conclusions The clinical manifestations of the patients with scrub typhus are diverse,and the presence of abnormal chest X-rays is shown to be associated with the disease severity.Physicians should have the awareness of scrub typhus to make the diagnosis and treatment properly.

OBJECTIVETo explore the impact of maternal hepatitis B surface antigen (HBsAg) carrier status on the occurrence of preterm birth.

METHODSWe analyzed pregnancy-related complications, outcomes and fetal growth index in 188 HBsAg positive singleton pregnant women during the period of May 2009 to July 2011, with 265 HBsAg-negative women with singleton pregnancies in the same period serving as controls.

RESULTSThe HBsAg-positive pregnant women showed a significantly higher incidence of placenta praevia than the control group (2.66% vs 0%, P=0.03), and the incidence of preterm delivery (<37 weeks) was also significantly higher in HBsAg-positive group (12.23% vs 6.04%, P=0.02). The incidences of gestational hypertension, preeclampsia, gestational diabetes mellitus, abnormal glucose tolerance, premature rupture of membranes, cesarean delivery, and postpartum hemorrhage showed no significant differences between the two groups (P>0.05), nor did the fetal birth weight, height, head circumference or Apgar scores at 1, 5, and 10 min (P>0.05). Logistic regression identified HBsAg positivity, abnormal ALT, placenta praevia, and severe preeclampsia as the risk factors for preterm delivery.

CONCLUSIONHBsAg carrier status can increase the risk of preterm delivery in pregnancy, but it does not seem to affect the fetal growth.

OBJECTIVETo explore the relationship between HSD11B2 polymorphisms and fetal growth during normal pregnancy.

METHODSThe HSD11B2 promoter/G-209A, G-194C, G-151A and G-126A genotypes were examined in 33 samples from Chinese Han subjects by gene sequencing. HSD11B2 (CA)n microsatellite polymorphism in the first intron was detected in blood samples from 187 maternal and newborn pairs by PCR-capillary electrophoresis.

RESULTSAll the HSD11B2 promoter/G-209A, G-194C, G-151A and G-126A genotypes were wild-type GG. The offspring birth weight and any ultrasound parameters describing late gestational fetal body shape were not significantly different between maternal or fetal SS, SL and LL groups or combined SS+SL and LL groups. When considering the relevant confounding factors (gestational age at delivery, newborn's gender, maternal body mass index before pregnancy, maternal weight at delivery and maternal age), the offspring birth weight and late pregnancy ultrasound parameters were still not associated with the maternal or fetal HSD11B2 (CA) n microsatellite polymorphisms.

CONCLUSIONSFetal and maternal HSD11B2 polymorphism is not related to fetal growth during normal pregnancy.

Objective: To analyze the epidemiological characteristics of acute paraquat(PQ)poisoning in children in southwest Shandong, and the risk factors for pulmonary interstitial fibrosis. Methods: This retrospective study was performed on the clinical data of children with acute PQ poisoning admitted from January 2013 to December 2017 in 12 hospitals in southwest Shandong.All participants were divided into pulmonary interstitial fibrosis group and no pulmonary interstitial fibrosis group on the basis of the chest CT 14 days after poisoning.The epidemiological characteristics and risk factors of pulmonary interstitial fibrosis were analyzed. Results: During the study period, a total of 307 children with acute PQ poisoning were admitted to 12 hospitals, of which 61 (19.87%) were suffering from acute PQ poisoning.Forty-nine cases with complete clinical data were analyzed, including 26 male and 23 female patients poisoned by oral.The age distribution ranged from 8 months to 14 years.Poisoning mainly occured from July to September of each year.The mortality of acute PQ poisoning was 8.2%(4/49), and the incidence of pulmonary interstitial fibrosis in survival patients was 44.4%(20/45). Statistical differences (P<0.05) were found between the pulmonary interstitial fibrosis and no pulmonary interstitial fibrosis, with regard to the times of blood purification, the time from poison exposure to blood purification, the application rate of glucocorticoids, the concentration of PQ in urine, the pediatric critical illness score, the time from poison exposure to gastric lavage, the white blood count at admission, serum creatinine, arterial blood lactate, PaO₂, PaCO₂, and PaO₂/FiO₂; however, there was no significant difference in the proportion of blood purification treatment, the mode of blood purification treatment, alanine aminotransferase, aspartate aminotransferase, urea nitrogen, creatine kinase and troponin.Stepwise logistic regression analysis showed that the time from exposure to poison to gastric lavage(OR=0.683, 95%CI 0.210-2.222)and to blood purification(OR=0.0133, 95%CI 0.004-0.042), the times of blood purification(OR=2.862, 95%CI 1.450-5.648), concentration of PQ in urine(OR=1.435, 95%CI 1.085-1.898), and the use of glucocorticoids(OR=0.190, 95%CI 0.048-0.757) were the risk factors for pulmonary interstitial fibrosis(P<0.05). Conclusion Early gastric lavage and blood purification, increasing the frequence of adminitrating purification appropriately, using low-dose glucocorticoids can reduce the incidence of pulmonary interstitial fibrosis of children with acute PQ poisoning.
