Cerebral small vessel disease (SVD) is an important subtype of cerebrovascular disease. It is also one of the major reasons for resulting in vascular cognitive impairment or dementia in the elderly. SVD is a small arteriovenous lesion in subcortex caused by a variety of causes, mainly causing subcortical lacunar infarction, white matter damage, microblecds and other pathological changes. There is evidence that vascular endothelial function and blood-brain barrier damage may result in small vessel structures and perivascular changes, which may be the initial factors.of causing SVD. Genetic susceptibility is also one of the risk factors that can not be ignored.

OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.

METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.

RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.

CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

OBJECTIVESince glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common hereditary hemolytic erythrocyte enzyme deficiency, most cases have single nucleotide mutations in the coding region, and current test methods for gene mutation have some missed detections, this study aimed to investigate the feasibility of RT-PCR sequencing in the detection of gene mutation in G6PD deficiency.

METHODSAccording to the G6PD/6GPD ratio, 195 children with anemia of unknown cause or who underwent physical examination between August 2013 and July 2014 were classified into G6PD-deficiency group with 130 children (G6PD/6GPD ratio <1.00) and control group with 65 children (G6PD/6GPD ratio≥1.00). The primer design and PCR amplification conditions were optimized, and RT-PCR sequencing was used to analyze the complete coding sequence and verify the genomic DNA sequence in the two groups.

RESULTSIn the G6PD-deficiency group, the detection rate of gene mutation was 100% and 13 missense mutations were detected, including one new mutation. In the control group, no missense mutation was detected in 28 boys; 13 heterozygous missense mutations, 1 homozygous same-sense mutation (C1191T) which had not been reported in China and abroad, and 14 single nucleotide polymorphisms of C1311T were detected in 37 girls. The control group showed a high rate of missed detection of G6PD deficiency (carriers) in the specimens from girls (35%, 13/37).

CONCLUSIONSRT-PCR sequencing has a high detection rate of G6PD gene mutation and a certain value in clinical diagnosis of G6PD deficiency.

OBJECTIVETo observe the curative effect of porous tantalum rod and Gugutou Huaisiyu Capsule (GHC) for steroid-induced osteonecrosis of femoral head (SONFH).

METHODSA total 60 hips of 50 SONFH patients were randomly assigned to the treatment group and the control group according to grouping time, 25 in each group (30 hips). Patients in the control group were implanted with porous tantalum rod, while those in the treatment group additionally took GHC (5 pills each time, three time per day for 2 successive months; and then twice per day for 4 successive months). Then all patients were followed-up to observe Harris hip score. The curative effect and the femoral head survival time were assessed.

RESULTSA total of 49 patients (59 hips) were followed-up. The Harris hip score of the two groups at the final follow-up was significantly improved after treatment, with statistical difference when compared with before treatment (P < 0.01). Besides, it was higher in the treatment group than in the control group. The curative effect and the survival time were superior in the treatment group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONSPorous tantalum rod combined GHC got better effect in treating SONFH. It could significantly improve the function of affected hips and prolong the survival time of femoral head.

OBJECTIVESevere Epstein-Barr (EB) virus infection is potentially a devastating process that often leads to death encountered in pediatrics recently. Inappropriate control of EB virus replication may cause severe infection resulting in multiple organ dysfunction. However, little information is available on pulmonary complications associated with EB virus infection. The aim of the present study was to investigate severe EB virus (EBV) infection complicated with lung injury in pediatric intensive care unit (PICU), including clinical characteristics, laboratory or imaging feature and outcomes.

METHODA total of 45 children with severe EBV infection seen in PICU of Shanghai Children's Hospital between January 2011 and December 2014 were retrospectively reviewed. According to clinical characteristics and imaging feature, 45 children were divided into non-lung injury group (n =27), lung injury without pulmonary fibrosis group(n = 12) and pulmonary fibrosis group (n = 6).

RESULTIn totally 45 cases of severe EBV infection, 21 (46.7%) were male and 24 (53. 3%) were female, mean age was 2. 4 years; 18 cases were complicated with lung injury, including 8 male and 10 female, median age was 31. 2 months. All of 18 cases presented with fever and cough, 15 of them exhibited dyspnea,12 cases were complicated with gasping, and 6 cases with ARDS. Eight cases accepted mechanical ventilation for acute respiratory distress; 6 cases who developed pulmonary fibrosis had tachypnea, refractory hypoxemia and hypercapnia, severe pulmonary air leak. The average EBV-DNA level in peripheral blood was 4. 42 x 10(6) copies/ml (range: 3. 25 x 10(3) - 6.59 x 10(7) copies/ml). Anti-EBV antibodies were positive in 41 cases, 18 cases were positive (+) for VCA-IgM, 15 cases were VCA-IgG and EA-IgG (+), 8 cases VCA-IgM and VCA-IgG (+). The radiographic findings revealed pulmonary interstitial infiltrates in all 18 cases with lung injury, 4 cases with segmental consolidation and 2 cases showed pleural effusions. HRCT scanning found EBV associated fibrosis including multifocal patches and diffuse ground-glass attenuation in both lungs, reticular opacities and honeycombing changes were observed 4 weeks after illness onset. There were significant differences in respiratory failure, PICU stay (days), Pediatric risk of mortality III (PRISM III) and pediatric clinical illness score(PCIS), serum TNF-α, EBV-DNA levels, percentage of NK cells and CD4+/CD8+ T cell ratio among non-lung injury group, lung injury without pulmonary fibrosis group and pulmonary fibrosis group (X2 =27. 12, F = 85. 23, 78. 23, 88. 68, 323. 80, 7. 35, χ2 = 6. 71, 12. 15; all P < 0. 05). COX regression analysis revealed that EBV-DNA and serum TNF-α levels were correlated with pulmonary fibrosis significantly (OR = 3. 92, P = 0. 04; OR = 5. 95, P = 0. 01). The patients with EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) had higher incidence of pulmonary fibrosis compared with non-EB-HLH (70% vs. 13%, χ2 = 4. 82, P = 0. 03). Of 18 cases, 8 cases died, including 3 cases with pulmonary fibrosis. The surviving cases with pulmonary fibrosis needed longer additional oxygen. Chest HRCT imaging of 3 cases with pulmonary fibrosis was improved at 6 months and oxygen therapy was discontinued at 18 months after discharge.

CONCLUSIONEB virus infection complicated with lung injury had higher incidence of respiratory failure, pulmonary fibrosis with a fatal outcome. EBV-DNA and serum TNF-α level were found to be statistically significant indicators of pulmonary fibrosis. Pulmonary fibrosis associated with severe EB virus infection may be reversible.
