Objective To evaluate clinical efficacy of multiple regimen combination in treatment of osteoporosis of perimenopausal or postmenopausal women. Methods From Jul. 2008 to Dec. 2009, 109 women with low bone mineral density (BMD) or osteoporosis treated in Department of Obstetrics and Gynecology, Affiliated Second Hospital, Wenzhou Medical College were enrolled randomly into 3 group,including 36 women in Group A managed by osteoform 1000 mg/d + alfacalcidol 0. 25 μg/bid orally, 40 women in group B managed by osteoform 1000 mg/d + alfacalcidol 0. 25 μg/bid + tibolone 1.25 mg/d orally and 33 women in group C managed by ostcoform 1000 mg/d + alfacalcidol 0. 25 μg/bid +bisphosphonates 70 mg/w orally. After 48 weeks BMD on lumbar 1 -4 (L1-4) and left femur were detected by X-ray. Bone alkaline phosphatase(BALP) ,cross linked clelopeptide of type Ⅰ collagen(CTX) and 25-hydroxychole calciferol [25 (OH) D3] was measured by enzyme linked immunosorbent assay (ELISA).Result Seven women (6. 4%, 7/109) were withdrawed form this study, including 2 cases losing follow up in group A, 3 cases stopping treatment in group B, 2 cases giving up treatment due to severe adverse effect (burning in upper abdomen) in group C. (1) Pain relieve: after 48 weeks treatment, women in 3 groups improved symptom of pain significantly, the rates of pain relieve were 85% (29/34)in group A, 92% (34/37) in group B and 94% (29/31) in group C. (2) BMD: BMD was improved significantly in women in 3 groups after treatment. BMD of L1-4 were (0.88±0.15) g/cm2 in group A,(0.89±0.18) g/cm2 in group B and (0.87±0.10) g/cm2 in group C before treatment, and converted to (0.90±0.01) g/cm2 in group A, (0.93±0.09) g/cm2 in group B and (0.91±0.11) g/cm2 in group C after treatment. BMD of left femur were (0.87±0.07) g/cm2 in group A, (0.87±0.07) g/cm2 in group B and (0.85±0. 12) g/cm2 in group C before treatment and converted to (0.90± 0.03) g/cm2 in group A, (0.91±0.08) g/cm2 in group B and (0.89 ±0.12) g/cm2 in group C after treatment. It was shown significantly different BMD between group B or C and group A (P < 0. 01), however, there was no significant different BMD between group B and C (P >0. 05). (3) Index of bone metabolism: BALP were (26±6) μg/L in group A, (26±9) μg/L in group B and (28±7) μg/L in group C before treatment and converted to (22±5) μg/L in group A, (20±9)μg/L in group B and (22±8)μg/L in group C after treatment, which showed statistical difference (P < 0.05). CTX were (0.85±0.20) ng/L in group A, (0.84±0.47) ng/L in group B, and (0. 88 ±0. 11) ng/L in group C before treatment and converted to (0. 81 ±0. 19) ng/L in group A, (0. 77±0.33) ng/L in group B, and (0.82 ±0. 14) ng/L in group C after treatment, which showed statistical difference (P < 0. 05). Conclusions Those 3 regimens combination could be used in treatment of osteoporosis by decreasing bone conversion, increasing bone density, decreasing bone absorption. Regimen A was only suitable for basic therapy,the other two regimens could provide better treatment.

Objective To investigate the efficacy and the course of desensitization treatment in bronchial asthma with positive specific IgE to dust mite in children. Methods A total of 105 children with bronchial asthma with positive specific IgE to dermatophagoides farinae allergens were randomized into the observation group and the control group. Children in the control group were treated to continue anti-asthma according to the routine of prevention and treatment children with asthma. Chinldren in the observation group were treated by dermatophagoides farinae drops in addition to the treatment of children in the control group. The recurrence of asthma was compared between two groups at 25 weeks post-treatment. At 25 weeks post-treatment , children in the observation group was randomly divided into the observation groupⅠand group Ⅱ. Children in the observation groupⅠreceived continuous treatment except for desensitization treatment. Children in the observation group II received the sublingual immunotherapy with dermatophagoides farinae drops (No.4) for 1 year in addition to the treatment in the observation groupⅠ. The recurrence of asthma was also compared between the two sub-groups. Results The rate and times of recurrence of asthma were lower in the observation group than those in the control group(P < 0.05), with no significant differences between the observation groupⅠand groupⅡ (P > 0.05). Conclusion The recurrent rate and frequency of asthma could be reduced by the sublingual immunotherapy with dermatophagoides farinae drops in children with asthma of positive specific IgE to dust mite. The course of treatment may be half year long.

Retrospective analysis of multi-slice computed tomography (MSCT) manifestations were conducted for 8 cases of pathologically confirmed primary pulmonary sarcomatoid carcinoma.And the relevant literature was also reviewed.The lesion sites were right upper lobe (n =5),lower lobe (n =2) and left upper lobe (n =1).One case was difficult to distinguish because of its huge mass and the remainder was all peripheral.With pseudocapsule (n =4),coarse calcification (n =1),hilar & mediastinal node metastasis (n =2) and cavity (n =1).The manifestations included extensive lung alveolar septal thickening & ground glass (n =1) and massive deep leaf & glitches (n =2).The scans were non-enhanced alone (n =1) and non-enhanced & enhanced (n =7).Six cases had shaped enhancement while another 5 uneven thickness of annular enhancement.And 4 cases had floating-ice change.Primary pulmonary sarcomatoid carcinoma is common in subpleural lung lobe.And the floating-ice sign is valuable in the diagnosis of sarcomatoid carcinoma.

Dura mater, rich in vasculature and immune cells, is the outermost layer of the central nervous system, and thus acts as the first barrier to protect brain. Meningeal lymphatic vessels and immune cells are main components of dural immunity, which respond to a variety of central nervous system diseases. Meanwhile, compared with brain parenchyma, dura mater communicates more with peripheral tissues and is more susceptible to medical interventions. Therefore, dura mater is a promising target to prevent, diagnose and treat intracranial diseases. Here dural immunity is clarified based on meningeal lymphatic vessels and dural immune cells, and current researches inquiring the role of dural immunity in infectious and immune diseases of central nervous system are summarized.

OBJECTIVE: To screen differentially expressed genes and gene pathways in L02 cell line stably expressing hepatitis C virus (HCV) Ib type nonstructural protein 4B (NS4B) mediated by lentiviral system, and to provide a basis for further research of molecular biological mechanism of NS4B gene in chronic hepatitis C and hepatocarcinogenesis. METHODS: NS4B stably overexpressed L02 cell line and negative control stable L02 cell line, designated as L02-NS4B and L02-mkate2 respectively, were resurrected and amplified in vitro. The differentially expressed genes between L02-NS4B and L02-mkate2 were determined by gene expression microarray from Human Gene 1.0ST. The significant pathways of the differential genes were selected by the Fisher's exact test and χ2 test according to kyoto encyclopedia of genes and genomes (KEGG) database. The differential expression levels of 5 selected genes including protein kinase C delta binding protein (PRKCDBP), tumor protein p53 (TP53), v-akt murine thymoma viral oncogene homolog 1 (AKT1), baculoviral IAP repeat containing 3 (BIRC3) and B-cell lymphoma 2-like1 (BCL2L1) from cDNA microarray data were further verified by real-time quantitative polymerase chain reaction (real-time QPCR). RESULTS: Between L02-NS4B and L02-mkate2, the genes with flurescence intensity ratio >1.2 or <0.8 were considered as differentially expressed genes. A total of 2 682 differentially expressed genes in the known 28 869 human genes were detected in L02-NS4B, 1 446 genes were upregulated and 1 236 genes were downregulated. A total of 41 involved pathways of up-regulated differential genes were identified by KEGG database, mainly including apoptosis, extracellular matrix receptor interaction, cell cycle, pathways in cancer and Toll-like receptor signaling pathway; and 20 involved pathways of down-regulated differential genes were identified, mainly including pathways in cancer, Wnt signaling pathway and cell cycle pathway. Of the 5 upregulated genes selected from cDNA microarray data, 3 genes showed the same differential expression pattern by real-time QPCR as that shown in cDNA microarray data, namely AKT1, BIRC3 and BCL2L1. The confirmation rate of real-time QPCR was 60%. CONCLUSION HCVNS4B can up-regulate or down-regulate the expression of many genes in L02 cells, thus affecting multiple signaling pathways relevant to cell apoptosis, cell cycle and carcinogenesis.

To explore the application of humanistic care in children’s fever clinics， the children’s fever clinics of Guangzhou Women and Children’s Medical Center conducted relevant research using narrative medicine as a guiding concept. This paper elaborated on the medical humanistic dilemmas and narrative care needs in children’s fever clinics， and focused on exploring the practice paths of narrative medicine in pediatric with Chinese characteristics from five dimensions， including the cultivation of nursing staff’s abilities of professional narrative and humanistic care， the establishment of health lectures featuring narrative patient education， the alleviation of medical anxiety for children and their families， related support of narrative nursing， and caring services. The aim was to improve the narrative care ability of nurses in children’s fever clinics， develop methods for pediatric patients that can eliminate the fear of seeking medical treatment， and protect children’s physical and mental health. A carrier of care， support， and emotional expression can be provided for parents. The foundation for nursing staff to achieve professional growth through narrative reflection can be laid. Thus， it can assist in establishing a life narrative community relationship between doctors and patients， and jointly explore the meaning of life.
