3.A perspective from transport protein particle: vesicle tether and human diseases.
Acta Physiologica Sinica 2014;66(1):1-6
Vesicle-mediated transport of proteins is a highly regulated, multi-step process. When the vesicle is approaching its target membrane compartment, many factors are required to provide specificity and tethering between the incoming vesicle and the target membrane, before vesicle fusion can occur. Tethering factors, which include multisubunit complexes, coiled-coil proteins, with the help of small GTPases, provide the initial interaction between the vesicle and its target membrane. Of the multisubunit tethering factors, the transport protein particle (TRAPP) complexes function in a number of trafficking steps, including endoplasmic reticulum (ER)-to-Golgi transport, intra- and post-Golgi traffic and autophagosome formation. In this review, we summarize the updated progress in structure and function of TRAPP complexes as well as human diseases caused by genetic mutations in TRAPP.

Objective:To observe any curative effect of combining hydraulic dilatation with radial extracorporeal shock waves on scapulohumeral periarthritis.Methods:A total of 132 patients with scapulohumeral periarthritis were randomly divided into a hydraulic dilatation group, a shock wave group and a combination group. The three treatments were applied for 3 weeks, before and after which shoulder range of motion was evaluated. Shoulder function was quantified using the Japanese Orthopaedic Association′s (JOA′s) shoulder function scoring, pain was reported using a visual analogue scale (VAS), and ability in the activities of daily living (ADL) was also quantified. Serum prostaglandin E2 (PGE2), β-endorphin (β-EP), interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were assayed.Results:The treatment response rate of the combination group (95%) was significantly higher than those of the hydraulic dilatation group (70%) and the shock wave group (82%). After the treatment, the average shoulder range of motion, JOA and ADL scores, and β-EP level in all 3 groups had improved significantly, while the average VAS score, and the PGE2, IL-6 and TNF-α levels had decreased significantly, but in each case the improvement in the combination group′s average was significantly greater than those of the other 2 groups. During the treatment there were no such adverse events as intra-articular infection, skin redness, numbness or palpitations.Conclusions:Combining hydraulic dilatation with radial extracorporeal shock waves significantly improves the treatment of scapulohumeral periarthritis. It can effectively promote the recovery of shoulder function and improve quality of life. Its greater effectiveness may be related to improving levels of PGE2, β-EP, IL-6 and TNF-α, and relieving pain and inflammation.

Objective To investigate the prevalence of nutritional risk (NRS2002) and malnutrition inhospitalized stroke patient and their nutritional intervention. Methods The stroke patients admitted to three de-partments of vascular neurology ward including cerebral hemorrhage, cerebral infarction and subarachnoid hemor-rhage in Beijing Tiantan Hospital from January 2018 to January 2019 were recruited using cluster sampling. Nutri-tional risk screening 2002 ( NRS 2002) was used to screen the nutritional risk of inpatients Malnutrition was as-sessed by criteria:(1) body mass index (BMI) <18. 5 kg/m2 with poorer general condition from January 2018 to January 2019;(2) Global leadership initiative on malnutrition ( GLIM) criteria were used except whole body muscle mass measurement from October 2018 to January 2019. The nutritional intervention for patients were closely observed during hospitalization. Results A total of 1532 patients were registered and1036 patients were included in the final analysis considering the inclusion and exclusion criteria. The prevalence of nutritional risk was 33. 0% ( 342/1036) . The prevalence of malnutrition based on BMI and GLIM criteria was 0. 9%( 9/1036) and 2. 5% (10/393) respectively. Among the 342 patients with nutritional risk, 112 patients received nutritional support therapy by tube feeding, but only 29 patients received nutritional support that met guideline standards. 81 patients received not standard nutritional support, and 2 patients received highly unregulated nutritional sup-port. No patients received sugar and electrolyte infusion, oral nutritional supplements ( ONS) , oral nutritional a-gents and compound nutrition intervention. The other 230 patients took hospital diet. Conclusion The prevalence of nutritional risk in hospitalized patients with cerebral hemorrhage, cerebral infarction or subarachnoid hemorrhage was high, and the prevalence of malnutrition was extremely low. There was a low proportion of nutri-tional support. High quality of large sample cohort studies will be conducted to show whether reasonable applica-tion of nutritional support therapy in patients with nutritional risk can improve patient outcome.

Background Chemical modification of RNA is a recent hotspot in the field of epigenetics, but the specific mechanism of chemical modification of RNA in aluminum neurotoxicity has not been fully reported. Objective To investigate the alterations of fat mass and obesity-associated protein (FTO), that demethylates N6-methyladenosine (m6A), and brain-derived neurotrophic factor (BDNF) in different brain regions of rats and rat adrenal pheochromocytoma differentiated cells (PC12 cells) following aluminum exposure. Methods Animal experiment: Twenty-four healthy male SD rats were randomly divided into a control group (normal saline) and 10, 20, and 40 μmol·kg−1 exposure groups according to body weight, with 6 rats in each group. Maltol aluminum [Al(mal)3] was injected intraperitoneally every other day for 3 months. Cell experiment: PC12 cells were divided into a control group and 100, 200, and 400 μmol·L−1 exposure groups exposed to Al(mal)3 for 24 h. After exposure, the learning and memory ability of rats was measured by water maze experiment, and the protein expression levels of FTO and BDNF in rat cortex (n=6) and hippocampus (n=6) samples as well as in PC12 cells (n=5) were determined by Western blotting. Results The results of water maze test showed that the escape latency of the 40 μmol·kg−1Al(mal)3 group was higher than those of the control group, the 10 μmol·kg−1Al(mal)3 group, and the 20 μmol·kg−1Al(mal)3 group on day 3, 4, and 5 of training (P<0.05). The retention time of the target quadrant of the 40 μmol·kg−1Al(mal)3 group was also reduced compared with that of the control group (P<0.05), indicating that aluminum exposure damaged the learning and memory ability of the rats. The Western blotting results showed that in the cortex, compared with the control group, the protein expression levels of FTO and BDNF in the aluminum treated groups were decreased (P<0.05). In the hippocampus, compared with the control group, the protein expression levels of FTO and BDNF in the 20 μmol·kg−1 and the 40 μmol·kg−1Al(mal)3 groups were decreased (P<0.05). In PC12 cells, compared with the control group, the protein expression levels of FTO and BDNF in the aluminum treated groups were decreased (P<0.05). Conclusion Aluminum-induced learning and memory impairment is related to a simultaneous reduction of FTO and BDNF protein expressions, suggesting that m6A methylation may be involved.

OBJECTIVE: To explore the relationship between occupational aluminum exposure and fasting blood glucose level in workers. METHODS: A cluster sampling method was used to select 178 occupational aluminum-exposed workers as the exposure group, and 178 workers without occupational aluminum exposure as the control group in a large aluminum factory in Shanxi Province. Glucose oxidase method was used to measure the fasting blood glucose level, and inductively coupled plasma mass spectrometry was used to measure the plasma aluminum level in these workers. A generalized linear model was used to analyze the correlation between plasma aluminum exposure level and fasting blood glucose in these workers. RESULTS: The blood aluminum level of workers in the exposure group was higher than that of the control group [median: 39.58 vs 16.67 μg/L, P<0.01]. The fasting blood glucose level of workers in the exposure group was higher than that of the control group [(5.33±0.79) vs(5.15±0.41) mmol/L, P<0.01]. The results of the generalized linear model analysis showed that the blood aluminum level of workers was positively correlated with their fasting blood glucose level after adjusting for age, body mass index, smoking, drinking, exercise, family history of diabetes, and incidence of diabetes(P<0.05). There was a dose-response relationship between the blood aluminum level and fasting blood glucose level of workers in the groups of junior high school and below and high school(all P_(trend)<0.01). There was no correlation found between blood aluminum level and fasting blood glucose level in the group of college and above(P_(trend)>0.05). There was a dose-response relationship between the blood aluminum level and the fasting blood glucose level in the workers in the non-exercise group(P_(trend)<0.01). There was no correlation found between the blood aluminum level and the fasting blood glucose level in the exercise group(P_(trend)>0.05). CONCLUSION: The blood aluminum level of workers exposed to occupational aluminum is positively correlated with their fasting blood glucose level. Higher education level or exercise can moderately reduce the effect of blood aluminum level on fasting blood glucose.
