Objective: To evaluate the efficacy and safety of reduced volume hepatectomy in treatment of advanced hepatic alveolar echinococcosis. Methods: The clinical data of 90 patients with advanced hepatic alveolar echinococcosis treated at the Qinghai Provincial People's Hospital from January 2017 to January 2019 were retrospectively analyzed. There were 41 males and 49 females, with an average age of 32 (range 11 to 58) years. The locations of the lesions, operations, complications and follow-up were analyzed. Results: 90 patients were treated with reduced volume focal hepatectomy, 38 with radical resection and 52 with quasi radical resection. The operation time was (361±22) min. The hospital stay was (22±2) day, and the blood loss was (781±37) ml. Red blood cells were transfused in 19 patients and plasma in 39 patients. Pringle’s maneuver was used in 12 patients, regional hepatic blood flow occlusion in 42 patients, and Glisson sheath occlusion in 26 patients. The total bilirubin, alanine aminotransferase and aspartate aminotransferase returned to normal in 3 to 14 days after operation. There were 12 patients who developed bile leakage, 41 pleural effusion and 26 effusion in the operation sites. A total of ninety patients were followed up for 2 to 24 months. There was no recurrence of echinococcosis after radical resection and no enlargement of residual lesions after quasi-radical resection. Conclusion Reduced-volume hepatectomy reduced the risk and difficulty of operation. The follow-up results were good. This approach provides a feasible scheme for treatment of advanced hepatic alveolar echinococcosis.

1,2,3,4,6-penta-O-galloyl-D-glucose (PGG) is one of the main active compounds of Guizhi Fuling capsule. Molecularly imprinted polymers (MIP) have high affinity toward template molecules synthesized by molecularly imprinted technology for its specific combined sites, which can overcome the shortcoming of traditional separation methods, such as complex operation, low efficiency, using large quantity of solvent and environmental pollution. In this paper, surface molecularly imprinted polymer (SMIP) was prepared by surface imprinting with PGG as the template molecule. Its adsorption capacity was measured by the scatchard equation. The separation of PGG from Guizhi Fuling capsule at preparatived scale was achieved with molecularly imprinted polymer as stationary phase and the purity was 90.2% by HPLC. This method can be used to prepare PGG from Guizhi Fuling capsule with large capacity and is easy to operate. It provides a new method for efficient separation and purification for other natural products.

The changes of microRNA expression in rat hippocampus after traumatic brain injury (TBI) were explored. Adult SD rats received a single controlled cortical impact injury, and the ipsilateral hippocampus was harvested for the subsequent microarray assay at three time points after TBI: 1st day, 3rd day and 5th day, respectively. We characterized the microRNA expression profile in rat hippocampus using the microRNA microarray analysis, and further verified microarray results of miR-142-3p and miR-221 using quantitative real-time PCR. Totally 205 microRNAs were identified and up-/down-regulated more than 1.5 times. There were significant changes in 17 microRNAs at all three time points post-TBI. The quantitative real-time PCR results of miR-142-3p and miR-221 indicated good consistency with the results of the microarray method. MicroRNAs altered at different time points post-TBI. MiR-142-3p and miR-221 may be used as potentially biological markers for TBI assessment in forensic practice.

OBJECTIVETo investigate the clinical, pathological and genetic characteristics in a family with autosomal dominant Emery-Dreifuss muscular dystrophy (AD-EDMD).

METHODSClinical data and skeletal muscle specimens were collected from two patients (the proband and her daughter) for pathological analysis. DNA samples of the proband and her family members (7 persons from 3 generations) were obtained for PCR amplification and direct DNA sequencing of the lamin A/C (LMNA) gene. Haplotype analysis was performed after the identification of mutation.

RESULTSThe proband had typical clinical manifestation of EDMD: joint contracture, progressive muscle weakness and atrophy and cardiac conduction dysfunction. Muscular pathology revealed myopathic changes combined with slight neuropathic changes. A heterozygous missense mutation 1583 (C to G)(T528R) was identified in exon 9 of the LMNA gene in the two patients, but not in other family members. Haplotype analysis indicated that the proband and her daughter shared the same causative haplotype.

CONCLUSIONThis is the first report of the phenotype and genotype of AD-EDMD in Chinese.

OBJECTIVEThe purpose of this study was to explore how obesity was covered in television news in China, including the trends over time and the characteristics of obesity-related news.

METHODSThe frame analysis was adopted to assess the content of obesity-related news broadcasted in China Central Television (CCTV) from 1982 to 2009. To investigate the characteristics of the news, the obesity-related news was divided into subgroups according to populations concerned, as well as the period in which the news was broadcasted. The differences between subgroups were examined.

RESULTSA total of 1 599 pieces of news reported obesity, in which 1 278 pieces (79.92%) aired in "wealthy" period (2006-2009). More news was concerned with adults (1 134, 70.92%). "Individual behavior" dominated most of the cause frames (389, 24.33%), solution frames (522, 32.65%), and responsibility frames (860, 53.78%). There was more news mentioning individual factors in news aired in "wealthy" period and news concerning children. The coverage of social-structure causes was higher in news concerning children, while the coverage of social-structure solutions was higher in news concerning children and news aired in "wealthy" period.

CONCLUSIONAlthough the coverage of obesity was modest, it showed an incremental trend as the economy grew. Obesity was mostly depicted as an individual problem in terms of responsibility, causes and solutions.
