OBJECTIVETo investigate the expression of occludin, ZO-1, MMP-2, and MMP-9 in cerebral microvasculature following Pulse Electromagnetic Field (PEMF) induced BBB permeability change.

METHODSSprague-Dawley rats were randomized into PEMF and sham exposed groups (n = 8). After exposure to PEMF at 0.5, 1, 3, 6, and 12 h, BBB permeability was measured by Evans-Blue extravasation. The expression of occludin, ZO-1, MMP-2, and MMP-9 were detected by real-time quantitative reverse transcriptase PCR and western blotting. MMP-2 and MMP-9 activity were detected by EnzChek gelatinase assay.

RESULTSCompared with the sham group, PEMF exposure led to increased permeability of the BBB to EB, which was prolonged after exposure. BBB permeability became progressively more severe, and recovered at 6 h. The gene and protein expression of occludin and ZO-1 were significantly decreased, while MMP-2 and MMP-9 expression were significantly increased after exposure to PEMF. All levels of expression recovered 12 h following PEMF.

CONCLUSIONChanges to BBB permeability were related to the alteration expression of tight junction proteins and matrix metalloproteinase after exposure to PEMF.

OBJECTIVETo explore the effects of mitogen activated protein kinase (MAPK) and extracellular signal-regulated kinases (ERK) on kidney injury in female BALB/c mice exposed to cadmium.

METHODTwenty-one female BALB/c mice were randomly divided into 3 groups, i.e. control group, low Cd exposure group (2.5 µmol/kg) and high Cd exposure group (10 µmol/kg) were exposed to normal saline, 2.5, 10 µmol/kg Cd, respectively, 3 times a week for 14 weeks. The kidney slice were stained by HE, PAS and Masson staining to observe the morphological changes. The expression levels of pERK, ERK, pp38, p38, pJNK and JNK proteins in kidneys were tested by Western blot assay.

RESULTSThe ratios of pERK/ERK, pp38/p38, pJNK/JNK in high Cd group were higher than those in the control group (P < 0.05). The ratio of pERK/ERK in low Cd group was higher than control group (P < 0.05). The expression levels of bcl-2, bax proteins and the ratio of bcl-2 to bax in Cd exposure groups decreased significantly, as compared with the control group (P < 0.05). The impairment of renal glomeruli and tubules were observed in HE, PAS and Masson staining slices of kidneys in mice exposed to Cd.

CONCLUSIONCdCl2 may induced renal injury by affecting the expression levels of MAPK.

This study reports a boy with psychomotor retardation and epilepsy due to maternal phenylketonuria (PKU). The boy was admitted at the age of 20 months because of psychomotor retardation and epilepsy. He had seizures from the age of 1 year. His development quotient was 43. He presented with microcephaly, normal skin and hair color. Brain MRI scan showed mild cerebral white matter demyelination, broadening bilateral lateral ventricle and foramen magnum stricture. Chromosome karyotype, urine organic acids, blood amino acids and acylcarnitines were normal. His mother had mental retardation from her childhood. She presented with learning difficulties and yellow hair. Her premarriage health examinations were normal. She married a healthy man at age of 26 years. When she visited us at 28 years old, PKU was found by markedly elevated blood phenylalanine (916.54 μmol/L vs normal range 20-120 μmol/L). On her phenylalanine hydroxylase (PAH) gene, a homozygous mutations c.611A>G (p.Y204C) was identified, which confirmed the diagnosis of PAH-deficient PKU. Her child carries a heterozygous mutation c.611A>G with normal blood phenylalanine. Her husband had no any mutation on PAH. It is concluded that family investigation is very important for the etiological diagnosis of the children with mental retardation and epilepsy. Carefully clinical and metabolic survey should be performed for the parents with mental problems to identify parental diseases-associated child brain damage, such as maternal PKU.

OBJECTIVETo establish a highly sensitive and specific assay to detect dengue virus (DENV) envelope protein domain III (EDIII) IgG antibody, and to explore its value in the diagnosis and seroepidemiological survey of dengue.

METHODSThe DENV EDIII IgG antibody capture ELISA was developed using the recombinant full-length DENV EDIII, which was prepared by Pichia yeast expression system as the capture antigen. The serum samples were collected from the same group of 35 DENV-1 patients of primary infection during disease period in 2006 and their follow-up phase in 2010; and the sensitivity of the assay was compared to that of the commercial Panbio DENV IgG ELISA.

RESULTSThe sensitivity of DENV EDIII IgG ELISA in detecting the serum samples from disease period and follow-up phase was 87% (20/23) and 94% (33/35), respectively; whereas the sensitivity of Panbio DENV IgG ELISA was 71% (25/35) and 0, respectively. The sensitivity of DENV EDIII IgG ELISA in detecting the serum samples from both periods was similar, without statistical significance (χ(2) = 0.946, P = 0.331). For serum samples from disease period, the sensitivity of DENV EDIII IgG ELISA was comparable with that of Panbio DENV IgG ELISA (χ(2) = 1.924, P = 0.165). However, DENV EDIII IgG ELISA demonstrated a significantly higher sensitivity than Panbio DENV IgG ELISA in detecting the serum samples from follow-up phase (χ(2) = 62.432, P = 0.000).

CONCLUSIONDENV EDIII IgG capture ELISA is highly sensitive in detecting IgG in the serum samples from either disease period or follow-up phase. This method might be a promising alternative for diagnosis and seroepidemiologic survey of dengue.

OBJECTIVETo explore the strategy for the treatment of chronic hepatitis B with YMDD mutation.

METHODSA total of 120 chronic hepatitis B patients with YMDD mutation were randomly assigned into four groups. In group A, patients received adefovir dipivoxil for 48 weeks. In group B, patients received adefovir dipivoxil in combination with lamivudine during the first 12 weeks and adefovir dipivoxil only for the following 36 weeks. In group C, patients received adefovir dipivoxil in combination with lamivudine for 48 weeks. In group D, patients received entecavir for 48 weeks.

RESULTSThe rate of rebound of alanine aminotransferase (ALT) was 30.0% (9/30), 10.0% (3/30), 6.7% (2/30), 10.0% (3/30) (P < 0.05) during the first 12 weeks, and one patient with severe hepatitis was found in group A. The positive rate of YMDD mutation was 17.9%, 0, 0, 0 at week 12. There was no significant difference in the level of ALT and the rate of HBeAg seroconversion after 48-week treatment (P > 0.05). At week 48, there was significant difference in the ALT normalization rate and undetectable HBV DNA rate between group C and group A, and also between group D and group A, and the rate of drug resistant genotype was 6.9%, 6.7%, 0, 0. Two patients had rtN236T mutation in group A, and one patient had rtN236T mutation and another one had rtA181V mutation in group B.

CONCLUSIONAdefovir dipivoxil in combination with lamivudine or entecavir are safe and effective therapies for chronic hepatitis B patients with YMDD mutation.

OBJECTIVETo investigate the cause of liver failure after hepatectomy for hepatocellular carcinoma and explore its prevention and treatment.

METHODSThe clinical data of 1000 patients with hepatocellular carcinoma undergone hepatectomy from July 2000 to June 2008 were retrospectively analyzed. There were 922 male and 78 female, aging from 21 to 89 years old.

RESULTSAmong the 1000 patients, there were 18 patients with liver failure after hepatectomy (1.8%). Among the 18 patients with liver failure, 13 patients were more than 65 years old, 14 patients were with more than 20% of indocyanine green retention rate at 15 minutes, 14 patients were with more than 1000 ml blood loss during operation, 6 patients were with F4/F3 liver fibrosis (Metavir Scores), and 9 patients were with less than 40.0% liver volume of residue liver.

CONCLUSIONSPatients with hepatocellular carcinoma with less than volume of residue liver, much more blood loss or transfusion, more than 20% of ICGR15, F4/F3 liver cirrhosis are prone to be with liver failure after hepatectomy. Artificial liver or liver transplantation may be the important alternative for liver failure after hepatectomy.

OBJECTIVETo probe into the effective acupuncture technique for deviation of the mouth in intractable facial palsy.

METHODSOne hundred and one cases of intractable facial palsy were randomly divided into an observation group (48 cases) and a control group (53 cases). Cuanzhu (BL 2), Sibai (ST 2), Jiache (ST 6) and Qianzheng (Extra) on the affected side were punctured in two groups. Additionally, three acupoints of the mouth were supplemented, named Dicang (ST 4), Kouheliao (LI 19) and Jiachengjiang (Extra) were added, and the sticking needle and traction method was adopted on them in observation group. the routine needling technique was applied in control group. The treatment was given once a day and 10-day treatment made one session. The changes in facial nerve function index (FNFI) were observed in 2 sessions of treatment.

RESULTSAfter treatment, FNFI in two groups increased significantly (both P < 0.01), but the improvement in observation group was better than that in control group (P < 0.01). In observation group, the basic recovery rate of FNFI was 87.5% (42/48), which was higher than that (67.9%, 36/53) in control group (P < 0.05).

CONCLUSIONThe sticking needle and traction method o three points is the quite effective approach in the treatment of deviation of the mouth in intractable facial palsy.
