Objective To investigate the relationship between quality of life and liver function in patients with chronic viral hepatitis B.Methods Psychological condition was investigated in 536 patients of chronic viral hepatitis B and 200 normal volunteers with self-administered 36-item short-form health survey questionnaire.These patients were divided into four groups based on their liver fuction normal,mild, moderate and severe damage,based on their serum activity of alanine aminotransferase(ALT)and serum level of bilirubin at the time of investigation.The patients with abnormal liver function at the beginning of the study would be retested when liver function recovered to normal level.Before and after comparison was made for those with abnormal liver function by Wilcoxon signed rank test.Trend test for the changes in liver function was performed by Jonckheere-Terpstra test.Results There was significant difference in physical functioning,role limitation due to physical health,bodily pain,general health perception,vitality,social functioning,role limitation due to emotional problems and mental health between patient with chronic viral hepatitis B and healthy volunteers.It was positively correlated with the degree of liver function damage. Scores of general health perception,role limitation due to physical health,role limitation due to emotional problems and vitality were relatively low in patients with chronic viral hepatitis B.Conclusions Quality of life in patients with chronic viral hepatitis B was far worse than that in healthy normal people,which related with their liver function.The more damage to liver function,the worse quality of life.Additional psychological treatment will be helpful for the patients with chronic viral hepatitis B other than drug treatment.

BACKGROUNDSeveral genetic polymorphisms in the endothelial nitric oxide synthase (eNOS) gene are associated with the pathogenesis of rheumatoid arthritis (RA). The objective of the present study was to investigate whether the two SNPs (T-786C and G894T) of the eNOS gene are associated with rheumatoid arthritis risk in a northern Chinese population.

METHODSIn this study, the eNOS genes T-786C and G894T were studied in 196 cases with rheumatoid arthritis and 201 healthy controls with gender, age and ethnicity matched. The two SNPs were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The analyses of association were statistically compared using the chi-square test with SPSS software for Windows.

RESULTSThe frequency of the -786C allele was significantly higher in the rheumatoid arthritis patients than in the healthy controls (19.64% vs. 14.18%, P < 0.05). However, the 894T allele of the eNOS gene was not increased in the rheumatoid arthritis patients compared to the healthy controls.

CONCLUSIONSIndividuals with the -786CC genotype have an increased risk of rheumatoid arthritis. Further study with an increased sample size is necessary for the study of the role of this SNP in rheumatoid arthritis.

OBJECTIVETo investigate the efficacy, safety and tolerance of bosentan, a dual endothelin receptor antagonist, in Chinese patients with idiopathic pulmonary arterial hypertension (IPAH).

METHODSTotally 79 IPAH patients (hemodynamic criteria confirmed by right heart catheterization) were included in this open-label, prospective multicenter study. Patients received 62.5 mg of bosentan twice daily for the first 4 weeks, and then up-titrated to 125 mg twice daily for another 12 weeks. The primary end point was the change in exercise capacity showed by six-minute walk distance (6MWD) from baseline to 16 weeks. Secondary end points included the change in World Health Organization (WHO) functional class, Borg dyspnoea scale and systolic pulmonary artery pressure measured by echocardiography.

RESULTSThe 6MWD increased from (343.7 ± 93.7) meters at baseline to (397.5 ± 104.4) meters after 16 weeks (P < 0.01), WHO functional class and Borg dyspnoea scale were also significantly improved after 16 weeks therapy compared to baseline levels (all P < 0.01). Furthermore, the systolic pulmonary artery pressure was significantly decreased from (97.8 ± 25.2) mm Hg (1 mm Hg = 0.133 kPa) to (92.8 ± 29.5) mm Hg (P < 0.05) after 16 weeks bosentan treatment. There was no patient withdrawal from this study for safety consideration.

CONCLUSIONBosentan therapy is well tolerated and can improve the exercise capacity and WHO functional class in Chinese IPAH patients.

OBJECTIVETo explore the computed tomography (CT) and magnetic resonance imaging (MRI) features of desmoid-type fibromatosis, and improve the diagnostic accuracy and understanding of the disease.

METHODSThe CT and MRI features of 18 cases of surgically and pathologically confirmed desmoid-type fibromatosis were reviewed retrospectively. Among the patients, 10 received CT pre- and post-contrast scanning, and 8 patients had MRI pre- and post-contrast scanning. The CT and MRI features were analyzed in comparison with the pathological findings.

RESULTSIn the extra abdominal cases, the tumors occurred in the head and neck in 3, in the dorsal part of the chest in 2, in the abdominal wall and groin area in 9, and in the peritoneal cavity in 4; concomitant Gardner syndrome was found in 1 case. In 4 cases the tumor occurred within 1 to 3 years after abdominal surgeries. Pathologically, the lesion was hard and composed of fusiform fibroblasts and myofibroblast. The cells showed no obvious heteromorphism with few karyokinesis, growing invasively and recurrent locally but without distant metastasis. Immunohistochemically, the fibroblasts and myofibroblasts expressed vimentin, and the myofibroblasts were positive for SMA. On CT and MRI, the lesion appeared benign with malignant growth pattern, and caused compression of the adjacent organs and vessels or encasement of the vessels; the border was unclear without encapsulation, and necrosis and calcification was scarce. The density and signal of the tumor were well distributed. Twelve patients displayed obvious enhancement and 5 showed uneven enhancement.

CONCLUSIONThe CT and MRI features of desmoid-type fibromatosis are characteristic, and CT and MRI are valuable modalities for the diagnosis and differential diagnosis of the tumor.

OBJECTIVETo analyze the CT/MRI features of Castleman's disease of the abdomen and pelvis.

METHODSCT/MRI images of 6 cases of pathologically confirmed Castleman's disease of the abdomen and pelvis were retrospectively reviewed. All the patients received plain CT scan and dynamic enhanced scan, and one had an additional MR scan.

RESULTSOne case was identified as the disseminated type with multicentric enlarged lymph nodes and hepatosplenomegaly, and 5 cases were found to have localized type, of which 3 had retroperitoneal, 1 had mesentery and 1 had pelvic lesions. On CT scan, all the 5 cases with localized lesions showed single, round or ellipse soft tissue masses, with intra-tumoral calcification in 2 cases, fascial thickening around the mass in 3 cases, and satellite nodules in 4 cases. Enhanced scanning revealed obvious enhancement in the arterial phase and continuous enhancement in the portal vein and delayed phase in all the lesions, with an attenuation pattern similar to that of large vessels; enlarged blood vessels within or around the mass were displayed in each case. In 4 cases, the intra-tumoral radial or fissured non-enhanced areas in early stage of enhancement were gradually filled up as the scan time was delayed. The patient receiving MRI showed hypo-intensity on T(1)WI and hyper-intensity on T(2)WI, presenting with an enhancement feature similar to that of CT.

CONCLUSIONCastleman's disease in the abdomen and pelvis is rare and liable to misdiagnosis, but its characteristic imaging features can help in the diagnosis and differential diagnosis.

Fragments encoding amino acids 76-130 in the linear conserved region (LCR) of A/Hubei/1/2010 (H5N1) HA2 was fused to hepatitis B core antigen (HBc) to generate a LCR-HBe virus-like particle (VLP). Results showed that the fusion protein of LCR-HBc was highly expressed in this prokaryotic expression system. The purified LCR-HBc particle stimulated high levels of IgG production in mice with a titer of > 1:12 800, and provided 50% cross-protection against lethal challenge by H1N1 viruses.

OBJECTIVETo investigate the efficacy of 2-month course of sleeping position correction in the treatment of positional plagiocephaly in infants aged <8 months.

METHODSA total of 73 infants with positional plagiocephaly between January 2015 and June 2016 were divided into treatment group (n=46) and control group (n=27) according to parents' wishes. The treatment group received sleeping position correction, while the control group received sleep curve mattress. The oblique diameters A and B in the two groups were measured and the cranial vault asymmetry (CVA) was calculated before and after treatment. The severity of positional plagiocephaly based on CVA was compared between the two groups before and after treatment. The Gesell Developmental Scale was used to determine the developmental quotients (DQs) in the motor, adaptive, language, and social domains in the two groups before and after treatment.

RESULTSBefore treatment, there were no significant differences in oblique diameters A and B, CVA, and DQs in the four specific domains between the two groups (P>0.05). After 2 months of treatment, the treatment group had a significantly greater oblique diameter B and a significantly smaller CVA than the control group (P<0.05); there were no significant differences in DQs in the four specific domains between the two groups (P>0.05). After treatment, both groups had significant improvements in oblique diameters A and B, CVA, and DQs in the motor and adaptive domains (P<0.01); moreover, the treatment group showed a significant improvement in the DQs in the social domain (P<0.01). There was no significant difference in the severity of positional plagiocephaly between the two groups before and after treatment (P>0.05).

CONCLUSIONSFor infants with positional plagiocephaly, sleeping position correction has better efficacy and is more convenient and economical than the sleep curve mattress, so it holds promise for clinical application.

OBJECTIVECystic fibrosis (CF) is rare in Chinese mainland. We present two cases of CF patients diagnosed by gene analysis. Their clinical manifestations and genetic mutation features are analyzed in this article. It will be of special interest to pediatricians in recognition of CF.

METHODThe clinical material of two CF patients who were diagnosed by gene analysis was retrospectively analyzed.

RESULTThe first patient is a 13-year-old girl. She had a complaint of recurrent fever and cough for 6 months, expectoration for 2 months and hemoptysis for 20 days. After 3 months of her birth, she was operated on for bullae of lung. She was susceptible to upper respiratory tract infection. There was no family history of recurrent wheeze and other special diseases. Aspergillus fumigatus specific IgE was at grade 3 and aspergillus fumigatus IgG was high. Pseudomonas aeruginosa was positive in sputum culture. Sweat testing was performed and Na+ was higher. Pulmonary CT indicated bronchiectasis. Nasal sinus CT showed optical density of soft tissue within maxillary sinus and chronic bilateral sinusitis. The electron microscopy of cilia suggested immobile cilia syndrome. A heterozygotic mutation (263T > G, 2909G > A) was found after CFTR genetic mutation analysis. Both her parents were carriers. She was treated with inhalation of nebulized hypertonic saline and postural drainage for a long time. And she got better during a follow up period of 1 year. The second patient was a 10-year-old girl who complained of recurrent expectoration for 3 years and shortness of breath for half a year. She had a history of sinusitis and steatorrhea. The family history was normal. Both the lipase and insulin level in blood serum was lower.Pseudomonas aerugino and Aspergillus fumigatus were both positive in sputum culture. Aspergillus fumigatus IgE was normal. Pulmonary CT indicated bronchiolitis and bronchiectasis. Nasal sinus CT showed bilateral maxillary sinusitis. CFTR genetic mutation analysis revealed a homozygous mutation (3196C > T). Her parents and relatives did not participate in this study. Unfortunately, this child died of respiratory failure 3 months after discharge.

CONCLUSIONCFTR gene mutation was a main cause of CF. Common symptoms are those of bronchiectasis, pancreatitis and sinusitis. The two Chinese patients were diagnosed by gene analysis. One had a heterozygous mutation (263T > G, 2909G > A) and the other had a homozygous mutation (3196C > T), not ΔF508 which is common in western countries.
