Chinese Pediatric Emergency Medicine 2011;18(5):397-399,402
Increased intracranial pressure is one of the most severe complications with significant mortality in children,so early diagnosis and treatment of this disorder is critical to save the patient's life.This article reviews etiologies,pathophysiology,and general principles of diagnosis and management of increased intracranial pressure.Based on primary diseases and clinical presentations,the goal of therapeutic strategy is to decrease intracranial pressure,avoid neurologic sequelae,and improve the outcome in patients.

Chinese Journal of Primary Medicine and Pharmacy 2017;24(1):142-145
Integrative medicine is the effective combination of dual diagnosis of Chinese medicine and western medicine.The combination can broaden the scope of clinical diagnosis and combine the local pathological changes with the overall response of the human disease.It can add a more comprehensive understanding of diseases for people.Clinically treated with combination of Chinese medicine and western medicine can achieve the complement of advantages.It is significant.Because the theory system of Chinese medicine compared with western medicine is different and the theory system of combination is not practical and standardized.The methods of clinical diagnosis and treatment are also different.So there are still some problems and deficiencies in the integrative medicine.In this study,through extensive literature research,as well as the clinical investigation in some integrative medicine hospitals and the collection of related clinical data,we compared and analyzed the academic ideas and different features of Chinese medicine and western medicine,analysed the status and the insufficience of current clinical integrative medicine.Finally,we put forward a series of effective strategies and methods for how to combine with integrative medicine in a specific,reasonable and effective way.

ObjectiveTo research in the essence of the caring experience of caregiver for children with eye enucleation, to find out the caring experience and caregiver's needs, to give them physical and mental nursing in order to make them cooperate with us and implement effective treatment to children.Methods12 caregivers for children with eye enucleation were given semi-structured interviews. The materials were analyzed, putted in order, and themes were got.ResultsThrough deep interview of 12 caregivers, five titles were summarized:overburdened psychology, limited schedule, requirement of health information, overload economic burden, to return and rebuild.ConclusionsThe results could help nurses to give more correct health education and psychological care to caregivers. Then caregivers can cooperate with nurses to give effective treatment to children, thus life quality of children with eye enucleation will be improved a lot.

Objective:To investigate the distribution of TNF microsatellite polymorphisms in Chinese Han population of Hubei province Methods:DNA samples were extracted from 164 unrelated healthy individuals’EDTA blood TNF microsatellite alleles were typed using PCR technique,followed by High Voltage denaturing PAGE,with silver staining At the same time,the PCR products were cloned and sequenced Results:Detected seven alleles and eleven kinds of genotypes at the TNFb locus;four alleles and seven kinds of genotypes at the TNFe locus The polymorphism information contents (PIC) were 0 67 and 0 33 respectively No deviation from Hardy Weinberg equilibrium were observed Statistical analysis showed,the distribution of TNFb and TNFe alleles in Chinese Han population were significantly different from that in European or in American Caucasian(P

Objective:To investigate the effect and the related mechanism of c-Myc on the proliferation,invasion and migration ability of malignant melanoma B16-F10 cells. Methods:We detected the expression of PIK3R3 in malignant melanoma and normal tis-sues. Efficiency of gene silencing of c-Myc and PIK3R3 was determined by qPCR and Western blot. We detected the proliferate ability of B16-F10 cells after silencing c-Myc and PIK3R3 using EdU assay. We detected the migration and invasion ability of B16-F10 cells after silencing c-Myc and PIK3R3 using wound healing assays and Transwell matrigel invasion assays. The expression of miR-199a after silencing c-Myc and PIK3R3 using qPCR. The expression of c-Myc and PIK3R3 was detected by qPCR after transfecting miR-199a mimics or miR-199a inhibitor. Dual-luciferase reporter assay system was used to detect miR-199a regulating c-Myc and PIK3R3. Results:Compared normal skin tissue,expression of PIK3R3 was significantly increased in malignant melanoma tissue;after silencing c-Myc and PIK3R3 gene,the proliferation,invasion and metastasis of melanoma cell line B16-F10 were significantly reduced;expression of miR-199a upregulated after silencing c-Myc and PIK3R3 genes, expression of c-Myc and PIK3R3 decreased after transfecting miR-199a mimics, expression of c-Myc and PIK3R3 upregulated after transfecting miR-199a inhibitor, dual luciferase reporter system test results revealed miR-199a can directly regulate c-Myc and PIK3R3 transcription activity. Conclusion: miR199a regulated the expression of c-Myc,then promote proliferation,migration and invasion in malignant melanoma cells.

Objective To investigate the effect of photodynamic therapy with chlorin e6 (Ce6) and 5-aminolevulinic acid (5-ALA) on mouse model of malignant melanoma. Methods The mouse model of malignant melanoma was established by injecting 0.1 ml A-375 cells (about 2?10 6 cells) under the right hind leg of BALB/c-6 mice,and that the yellowish white node appears at injection site proves the successful model. Twenty-four of 27 successful mouse models were irradiated at the tumor site with semiconductor laser (wavelength 652 nm) with a total dose of 100 J/cm 2 . Before laser exposure,the mice were treated with 10% 5-ALA by topical compress for 2 h or 7.5 mg/kg Ce6 by intraperitoneal injection for 1 hour or 5-ALA topical application combined with intraperitoneal injection of Ce6 (n=6 in each group). Another six mice as control only underwent PDT. One week after PDT,the mice were killed,the tumor mass was peeled off and weighed,whether the metastasis occurred or not was detected,and the tumor,liver,spleen,lung,kidney were sent to histopathological examination. Results The tumor weight in 5-ALA group,Ce6 group,and the combined group had significant difference as compared with control group (P0.05). The dehydration and scab formation and necrosis could be seen in tumor sites at 1 week after PDT. The cell collapse and necrosis,subdermal thrombosis and cell outline clouding could be observed by histopathological examination. Metastasis of melanoma were found in 5-ALA group,Ce6 group,and the combined group. Conclusion PDT with Ce6 and 5-ALA could kill the malignant melanoma effectively in animal experiment but could not affect the metastasis of melanoma.

Objective To construct a library of long serial analysis of gene expression (LongSAGE) and investigate the characteristics of gene expression in the yeast phase of C. albicans. Methods A LongSAGE library was constructed with long serial analysis of gene expression (LongSAGE). Results A total of 17 773 tags, representing specific 7 333 transcripts, were extracted from 1 000 sequence files in the yeast phase of C. albicans. Tags matching single gene accounted for 16.65%, tags matching multiple genes accounted for 6.59%, tags for hypothetical protein accounted for 16.27%, tags for genome and cosmid accounted for 1.64%, and novel tags accounted for 58.86%. Eleven tags in 33 tags whose expression frequencies exceeded 35 may be new expression sequences. Conclusion LongSAGE is not only a powerful method in investigating the gene expression profiling, allowing the analysis of the expression of thousands of transcripts in a quantitative manner without prior sequence information, but also in finding new genes.
