Objective To construct the pGEX-4T-2-CblN/Grb2, express and purify the corresponding chimeric protein; To investigate whether the chimeric CblN/Grb2 possesses ubiquitin ligase activity. Methods Total RNA of SK-BR-3 cells were isolated and reversely transcribed into cDNA, which were used as templates to amplify Grb2 SH2 by PCR. The gene fragment encoding the N-terminal part of Cbl protein (named as CblN) was amplified by PCR using pEFHACbl plasmid encoding human Cbl as templates. BamH I and EcoR V restriction enzyme digestion sites were introduced into both flanks of SH2 by overlapping extension PCR and the modified gene were cloned into pcDNA3.1(+). The pcDNA3.1(+)-CblN/Grb2 was obtained by replacing SH2 of CblN with Grb2SH2 and then used as templates to amplify CblN/Grb2 by PCR. The pGEX-4T-2-CblN/Grb2 was constructed by subcloning CblN/Grb2 into the prokaryotic expressing vector pGEX-4T-2. The GST-CblN/Grb2 fusion protein was expressed in E. coli of DH5? under IPTG induction and further purified with Glutathione Sepharose 4B. In vitro ubiquitination assay was performed to investigate whether the GST-CblN/Grb2 fusion protein is able to mediate auto-ubiquitinating reaction, namely whether it possesses ubiquitin ligase activity. Results The fusion expressing vector of pGEX-4T-2-CblN/Grb2 was successfully constructed; The GST-CblN/Grb2 fusion protein was correctly expressed and purified; In vitro ubiquitination assay indicated that GST-CblN/Grb2 fusion protein is able to mediate auto-ubiquitinating reaction and therefore possesses ubiquitin ligase activity. Conclusion Expression, purification of GST-CblN/Grb2 and identification of its′ activity have laid the foundation for further study of chimeric ubiquitin ligase′ effects on the growth of HER2 positive tumor cells.

Zoonoses are a class of infectious diseases that are transmitted from animals to humans. More than 200 known types of zoonoses have been reported across the world until now. Among 1 400 pathogens of human infectious diseases, approximately 61% are zoonotic origin, and 75% human emerging infectious diseases are zoonoses. These zoonoses pose a great threat to human and animal health and decrease livestock production. To effectively tackle the persistent challenges resulting from zoonoses, WHO collaborates with member governments, academia, non-governmental and charitable organizations, and regional and international partners to prevent and manage zoonotic threats and their public health, social and economic impacts. Although great success has been achieved in the management of zoonoses, there are still multiple challenges for zoonoses control in China due to environmental, climate, socioeconomic factors and antimicrobial resistance. Based on the One Health concept, the integration of modern biological, information, artificial intelligent and big data tools through multidisciplinary and multi-sectorial collaborations may facilitate the containment and elimination of zoonoses.

BACKGROUND: Extended high frequency audiometry is able to detect early cochlea damage. So it is useful in monitoring ototoxic, senile and noise induced hearing loss.OBJECTIVE: To study with extended high frequency audiometry the auditory function of people in highland of qinghai province without noise pollution and evaluate the sensitivity of this method in diagnosing early noise induced hearing loss. To provide the epidemiological data for early control of noise induced hearing loss in this area.DESIGN:It is a transverse comparison among normal people in two areas.SETTING: This study was cooperated by the Otolaryngeal Department of Gulou Hospital affiliated to Nanjing Medical College, the Otolaryngeal Department of Xijing Hospital of the Fourth Medical College and Auditory Research Center of Giessen University, Germany.PARTICIPANTS: Totally 300 people lived in highland of qinghai province received hearing test including extended high frequency audiometry. At the same time another 300 people were chosen in Nanjing city as control group.METHODS: The subjects in the two groups received the whole set of hearing tests including extended high frequency audiometry and answered a questionnaire about their personal history. The mean hearing thresholds from 0. 25-16 kHz between the two groups were compared with t-test.MAIN OUTCOME MEASURES: The difference of mean hearing thresholds from 0. 25-16 kHz between the two groups.RESULTS: There was no significant difference between hearing threshold of low frequencies and speech frequencies. The hearing threshold of high frequencies rose with the stepping-up of testing frequencies which made the possibility of measuring the hearing threshold reduced. But the hearing threshold above 6 kHz of the people in area without noise pollution was significantly higher than that of the control( P ＜ 0.05) . No difference between children and adolescence was found in the 2 groups. The epidemiological data revealed that the people without noise pollution had unperceptible hearing damage compared with the control group.CONCLUSION: The damage of impulsive noise to hearing began at 20 kHz and developed from 20 kHz to 10 kHz. If it was not protected, it would be extended to the speech frequencies and the hearing loss would get worse. So the extended high frequency audiometry was thought helpful to screen noise induced hearing loss early.

OBJECTIVETo observe the clinical efficacy of comprehensive Western medical treatment plus Compound Yindan Decoction (CYD) in treatment of acute cholestatic hepatitis (ACH).

METHODSUsing randomized controlled study, 60 ACH patients in line with inclusive criteria were randomly assigned to the treatment group (treated by comprehensive Western medical treatment plus CYD) and the control group (treated by comprehensive Western medical treatment alone), 30 in each group. Scores for symptoms and levels of liver functions [total bilirubin (TBIL), direct bilirubin (DBIL), alkaline phosphatase (ALP), glutamyl transpeptidase (GGT), total biliary acid (TBA)] were observed before and after treatment.

RESULTSCompared with before treatment in the same group, total scores for symptoms decreased in the treatment group and the control group at the end of the 1st and the 4th week after treatment (all P < 0.05). Compared with the control group, total scores for symptoms decreased in the treatment group at the end of the 1st week (P < 0.05). Compared with before treatment, serum levels of TBIL, DBIL, ALP, GGT, and TBA all decreased in the two groups at the end of the 4th week after treat- ment (P < 0.01). Compared with the control group, serum levels of TBIL, DBIL, ALP, GGT, and TBA all decreased in the treatment group at the end of the 1st and the 2nd week after treatment (P < 0.05). Compared with the control group, the average time for TBIL and DBIL decreasing to the level less than five times the normal value was significantly shorter in the treatment group (P < 0.05).

CONCLUSIONCYD could significantly improve clinical symptoms of ACH patients, decrease serum levels of TBIL and DBIL, reduce serum levels of ALP, GGT, and TBA, obviously improve cholestasis, and promote the recovery.

BACKGROUND: Full-thickness skin graft was a base for bum and plastic surgery, while uniform pressure and regional brake were key factors to ensure skin graft survival and avoid from necrosis. Traditionally, package and pressurized fixation were performed after skin transplantation; however, it induced residual dead space and unclear skin graft fixation, as well as suturing scar.OBJECTIVE: To study the effect of vacuum sealing drainage applied to full-thickness skin graft.METHODS: A total of 8 New Zealand rabbits were used to establish full-thickness skin graft models in three regions of bilateral spine. Vacuum sealing drainage, traditional pressurized suture and common wrapping were performed in the three regions, respectively. The skin graft survival was observed, and survival rate was calculated at 14 and 21 days. On the 3rd, 7th, and 14th days, samples were selected from skin graft and stained. The morphology was observed under light microscope and transmission electron microscope. The time to remove the drain vessel was that when the fluid was not increased or the fluid was clear.RESULTS AND CONCLUSION: The survival rate of vacuum sealing drainage group was significantly higher than that in other two group (P < 0.05), while the survival rate of traditional pressurized suture group was significantly higher than that in the common wrapping group (P< 0.05). Morphology examination demonstrated that regional cuticular layer was necrotic in the vacuum sealing drainage group after early skin transplantation, while inflammatory cell infiltration, fibroblast degeneration, and mitochondrial swelling were also observed. At later skin transplantation, fibroblast and basal cell were proliferated, and function of mitochondria and plasmid was active. This suggested that vacuum sealing drainage promoted survival rate of skin graft.
