Abstract
Objective: To evaluate the diagnostic value of gene testing in familial hypercholesterolemia (FH) in patients with premature myocardial infarction(PMI). Methods: This study was a single center cross-sectional study. A retrospective analysis was made on PMI patients who visited the People's Hospital of Peking University from May 1, 2015 to March 31, 2017. Clinical data of patients was collected and gene testing of FH related genes low density lipoprotein receptor (LDLR), proprotein convertase subtilisin/kexin type 9 (PCSK9), apolipoprotein B(APOB) and low density lipoprotein receptor adaptor protein 1(LDLRAP1) was carried out. Clinical diagnosis of FH patients was performed using Simon Broome criteria, DLCN criteria, and FH Chinese expert consensus. Results: There were 188 males (83.6%) among 225 PMI patients, and the age of the first myocardial infarction was (46.6±7.2) years old. Ten patients carried FH pathogenic or possibly pathogenic mutations (4.4%). Compared with Simon Broome standard, DLCN standard and FH Chinese expert consensus, gene testing increased the diagnostic rate of FH by 53.3%, 33.3% and 42.1% respectively. Conclusion: Gene testing is helpful to improve the diagnosis of FH, and it is important to start the standard treatment of FH as early as possible in patients with premature myocardial infarction.

Abstract
Objective: To investigate whether rosuvastatin acts on lymphatic system and influences lymphatic system-mediated reverse cholesterol transport to play an anti-atherosclerosis role. Methods: Forty-eight apolipoprotein E-/- mice fed a high fat diet were used to construct the atherosclerosis model. They were randomly divided into 4 groups with 12 rats in each group. They were treated with rosuvastatin, vascular endothelial growth factor-C (VEGF-C) and rosuvastatin+VEGF-C inhibitors as experimental group, and no intervention measures were given in control group. After 8 weeks, aortic plaque area, high density lipoprotein cholesterol (HDL-C) content in lymph fluid, the function of popliteal lymphatic drainage of peripheral Evans blue, and the ability of lymphatic system to transport peripheral cell membrane red fluorescent probes to label high-density lipoprotein (HDL) were detected. Subsequently, the effects of rosuvastatin on proliferation, migration and tubular function of lymphoendothelial cells and the expression of scavenger receptor class B type 1 (SR-B1) on lymphoendothelial cells at different concentrations were detected. Results: Compared with the control group, Rosuvastatin and VEGF-C could reduce the area of aortic atherosclerotic plaque (P<0.05). In addition to rosuvastatin plus VEGF-C inhibitor, the intra-aortic plaque area increased (P<0.05). Compared with the control group, Rosuvastatin could increase the content of HDL-C in lymphatic fluid (P<0.05), enhance the drainage function of lymphatic vessels, and enhance the capacity of HDL in the transport tissue fluid of lymphatic system. Compared with the control group, VEGF-C increased the content of HDL-C in mouse lymph fluid (P<0.01), enhanced the drainage function of popliteal lymphatic canal, and enhanced the ability of lymphatic system to transport HDL. With the addition of VEGF-C inhibitor on the basis of rosuvastatin, the content of HDL-C in lymph fluid was reduced, the drainage of popliteal lymphatic canal was interrupted, and the ability of lymphatic system to transport HDL was reduced. Western blotting showed that rosuvastatin increased the protein expression of SR-B1. Conclusion: Rosuvastatin can promote the proliferation, migration and tube formation of lymphatic endothelial cells. At the same time, SR-B1 expression on lymphatic endothelial cells is promoted, thus enhancing the lymphatic system mediated cholesterol reversal transport and playing the role of anti-atherosclerosis.

Abstract
The measurement of the energy spectrum of cosmic ray helium nuclei from 70 GeV to 80 TeV using 4.5 years of data recorded by the Dark Matter Particle Explorer (DAMPE) is reported in this work. A hardening of the spectrum is observed at an energy of about 1.3 TeV, similar to previous observations. In addition, a spectral softening at about 34 TeV is revealed for the first time with large statistics and well controlled systematic uncertainties, with an overall significance of 4.3σ. The DAMPE spectral measurements of both cosmic protons and helium nuclei suggest a particle charge dependent softening energy, although with current uncertainties a dependence on the number of nucleons cannot be ruled out.

Abstract
Alzheimer's disease (AD) is characterized by memory dysfunction, Aβ plaques together with phosphorylated tau-associated neurofibrillary tangles. Unfortunately, the present existing drugs for AD only offer mild symptomatic cure and have more side effects. As such, developments of effective, nontoxic drugs are immediately required for AD therapy. Present study demonstrates a novel role of Chinese medicine prescription Yuan-Hu Zhi Tong (YZT) in treating AD, and it has substantiated the in vivo effectiveness of YZT in two different transgenic mice models of AD, namely P301S tau and 3XTg-AD mice. Oral treatment of YZT significantly ameliorates motor dysfunction as well as promotes the clearance of aggregated tau in P301S tau mice. YZT improves the cognitive function and reduces the insoluble tau aggregates in 3XTg-AD mice model. Furthermore, YZT decreases the insoluble AT8 positive neuron load in both P301S tau and 3XTg-AD mice. Using microarray and the "Connectivity Map" analysis, we determined the YZT-induced changes in expression of signaling molecules and revealed the potential mechanism of action of YZT. YZT might regulate ubiquitin proteasomal system for the degradation of tau aggregates. The research results show that YZT is a potential drug candidate for the therapy of tau pathogenesis and memory decline in AD.

Abstract
Chronic critical illness (CCI) refers to a group of critically ill patients who survive the acute phase of intensive care, but with persistent organ dysfunction, thus entering a chronic period of continuous dependence on life support system, and still need to stay in intensive care unit (ICU) for a long time. Persistent inflammatory response-immunosuppression-catabolic syndrome (PICS) is the main pathophysiological feature of CCI. Three factors interact to form a vicious circle, leading to poor prognosis. Nutritional support therapy is a key link in the comprehensive treatment of CCI. Enteral nutrition (EN) should be started as soon as possible if conditions permit. If EN can not be implemented, temporary or transitional parenteral nutrition (PN) should be used, and EN should be added gradually in time. At the same time, the amount of PN should be gradually reduced. When EN meets more than 60% of patients' energy and protein requirements, PN can be considered to be discontinued. The main strategies and functions of CCI nutritional support therapy are as follows: strengthening high protein supply to correct negative nitrogen balance and inhibit catabolism, selecting branched chain amino acids (BCAA) to promote anabolism, using immunomodulators (arginine, ω3 polyunsaturated fatty acids) to improve immune suppression and inflammatory response, supplementing micronutrients (vitamins and trace elements) to counteract the decrease in intake and the increase in consumption, and adding probiotics to maintain the intestinal microecological balance, and so on. Reasonable nutritional support therapy not only improve malnutrition of CCI patients, but also help to reduce complications, thus speeding up rehabilitation, improving prognosis, shortening ICU hospitalization time, and even reducing mortality.

Abstract
The precise measurement of the spectrum of protons, the most abundant component of the cosmic radiation, is necessary to understand the source and acceleration of cosmic rays in the Milky Way. This work reports the measurement of the cosmic ray proton fluxes with kinetic energies from 40 GeV to 100 TeV, with 2 1/2 years of data recorded by the DArk Matter Particle Explorer (DAMPE). This is the first time that an experiment directly measures the cosmic ray protons up to ~100 TeV with high statistics. The measured spectrum confirms the spectral hardening at ~300 GeV found by previous experiments and reveals a softening at ~13.6 TeV, with the spectral index changing from ~2.60 to ~2.85. Our result suggests the existence of a new spectral feature of cosmic rays at energies lower than the so-called knee and sheds new light on the origin of Galactic cosmic rays.

Abstract
OBJECTIVE To investigate the role of microRNAs (miRNAs) in mediating intercellular signaling. METHODS Microparticles (MP) from HUVEC and 293T were isolated by sequential centrifugation. THP-1 was co-cultured with microparticles. And then the migration of THP-1 was measured by transwell. real-time PCR and Western blotting were used to study the related mechanisms. RESULTS Compared with the microparticles from 293T, MP from HUVEC could promote the migration of monocytes (P<0.05) and upregulate the expression of CXCR4 mRNA and protein (P<0.05). MiRNA-126 deficient MP could downregulate the migration of monocytes (P<0.05) and the expression of CXCR4 mRNA and protein (P<0.05) compared with miRNA-126 abundant MP. CONCLUSION Microparticles from HUVEC could promote the migration of monocytes. As carriers, microparticles could mediate intercellular signaling.

Abstract
Mercury concentrations of flue gas at inlet/outlet of the flue gas cleaning, electrostatic demister, reclaiming tower, acid plant, and mercury contents in zinc concentrate and by-products were measured in a hydrometallurgical zinc smelter. The removal efficiency of flue gas cleaning, electrostatic demister, mercury reclaiming and acid plant was about 17.4%, 30.3%, 87.9% and 97.4% respectively. Flue gas cleaning and electrostatic demister captured 11.7% and 25.3% of the mercury in the zinc concentrate, respectively. The mercury reclaiming tower captured 58.3% of the mercury in the zinc concentrate. About 4.2% of the mercury in the zinc concentrate was captured by the acid plant. Consequently, only 0.8% of the mercury in the zinc concentrate was emitted to the atmosphere. The atmospheric mercury emission factor was 0.5 g t(-1) of zinc produced for the tested smelter, indicating that this process offers the potential to effectively reduce mercury emissions from zinc smelting.

Abstract
Effectiveness and mechanism of action of andrographolide on the recovery of Pseudomonas aeruginosa susceptibility to antibiotics was investigated. In the presence of andrographolide, the Mueller-Hinton broth dilution method measured minimal inhibitory concentrations (MIC) of ceftazidine, cefpirome, chloramphenicol, L-ofloxacin, kanamycin, imipenem and meropenem. Real-time fluorescence quantitative polymerase chain reaction was used to determine mexB mRNA expressions in P. aeruginosa PAO1 strain and MexAB-OprM overexpressing strain. Relative mexB mRNA expression was detected in both strains incubated for 3 and 9 h. When andrographolide-treated groups were compared with controls, the MIC of ceftazidine, cefpirome, L-ofloxacin and meropenem for both strains decreased, and the relative mexB mRNA expression was significantly lower, although between andrographolide groups there were no significant differences. Compared with the inactivated quorum-sensing system, relative amounts of mexB mRNA in the PAO1 strain and MexAB-OprM overexpressing strain in the activated quorum-sensing system increased 10- and 30-fold, respectively. Andrographolide recovered P. aeruginosa susceptibility to antibiotics and reduced the MexAB-OprM efflux pump expression level.

Abstract
To investigate the frequency and risk factors of major depressive disorder (MDD) after mild to moderate traumatic brain injury (TBI), 69 TBI and 52 general trauma (GT) patients were prospectively recruited and studied at 3-months postinjury. There was a nonsignificant difference in the proportion of MDD patients in the TBI and GT groups. Therefore, a composite MDD group (TBI and GT patients) was compared to patients who were nondepressed. Female gender was related to MDD, but no other risk factors were identified. MDD was associated with disability (Glasgow Outcome Scale, Community Integration Questionnaire) and cognitive impairment. MDD was comorbid with posttraumatic stress disorder. Implications for postacute management of mild to moderate TBI are discussed.

Abstract
Previous studies of postconcussional disorder (PCD) have utilized a dimensional approach (i.e., number and/or severity ratings of symptoms) to study postconcussional symptoms. This study used a syndromal approach (modified form of the DSM-IV criteria) for investigating risk factors for developing PCD, 3-months postinjury. The head trauma requirement was waived in order to determine specificity of symptoms to traumatic brain injury. Preliminary results from this ongoing study indicated significant risk factors including female gender, poor social support, and elevated self-reported depressive symptoms at 1-month postinjury. Comorbidities included concurrent diagnosis of major depressive disorder and/or posttraumatic stress disorder. Hispanics were significantly less likely to develop PCD than other racial/ethnic groups. PCD resulted more frequently from motor vehicle accidents and assaults. Screening tests for PCD risk factors/comorbidities performed shortly after injury (i.e., during routine follow-up clinic appointments) coupled with appropriate referrals for psychoeducational interventions and support groups may avoid prolonged loss of productivity and poor perceived quality of life in these patients.

Abstract
OBJECTIVE To explore an ideal way of small vessel anastomosis for microsurgery. METHODS Anastomosis of both carotid arteries were performed in 20 rabbits. One side of the arteries were anastomosed with anastomotic clips, the other side of the arteries, as comparison, were anastomosed with suture. The vessels were harvested at first and 14th day after operation and were evaluated using operating microscope, light microscope and electronic microscope. RESULTS The average anastomotic time for suture was about 15 minutes, while for the clips was 2 to 5 minutes. There were no difference in patency between the two techniques. Endothelialization at the anastomotic sites were both completed 14 days postoperatively. However, for the anastomotic clips, there were no endothelia damage and foreign bodies formation inside the vessels. CONCLUSION This experiment has confirmed that the anastomotic clip's procedure provides a very safe and easy way to perform anastomosis and reduce the incidence of thromboses.

Abstract
OBJECTIVE To investigate the clinical application of subdermal vascular network skin flap pre-fabricated by ultrasonic liposuction in reconstruction of digital avulsion. METHODS Forty-seven injured fingers of 23 cases were treated from June 1997 to February 2000. Conventional abdominal skin flap was elevated, according to the size of digital avulsion, and subcutaneous fat was removed with scissors. Ultrasonic liposuction technology was adopted, in order to minimize the injury of subdermal vascular vessels, to remove the fat particles close to the vascular network. Finally, the pre-fabricated skin flap was used to repair the digital avulsion. The vascular pedicle was severed in 5 to 7 days after operation. The range of skin flap was 4 cm x 3 cm to 8 cm x 7 cm, and the ratio of length and width was (2 to 3) to 1. RESULTS All the skin flaps were survived. Twenty-one patients were available for postoperative follow-up for 6 to 24 months. The motion of interphalangeal joint achieved functional recovery, and the sensation of pain, temperature and taction recovered well. CONCLUSION Ultrasonic liposuction does not obviously injure the subdermal vascular network skin flap, it is a simple and safe method for treatment of digital avulsion.

Abstract
OBJECTIVES (1) A study of verbal learning and memory in children who had sustained a closed head injury (CHI) at least 3 months earlier. (2) To relate memory function to focal brain lesion and hippocampal formation volumes using morphometric analysis of MRI. METHODS A group of 245 children who had been admitted to hospital for CHI graded by the Glasgow coma scale (GCS), including 161 patients with severe and 84 with mild CHI completed the California verbal learning test (CVLT) and underwent MRI which was analysed for focal brain lesion volume independently of memory test data. Brain MRI with 1.5 mm coronal slices obtained in subsets of 25 patients with severe and 25 patients with mild CHI were analysed for hippocampal formation volume. Interoperator reliability in morphometry was satisfactory. RESULTS Severity of CHI and age at study significantly affected memory performance. Regression analysis showed that bifrontal, left frontal, and right frontal lesion volumes incremented prediction of various learning and memory indices after entering the GCS score and age into the model. Extrafrontal lesion volume did not contribute to predicting memory performance. CONCLUSIONS Prefrontal lesions contribute to residual impairment of learning and memory after severe CHI in children. Although effects of CHI on hippocampal formation volume might be difficult to demonstrate in non-fatal paediatric CHI, further investigation using functional brain imaging could potentially demonstrate hippocampal dysfunction.

Abstract
The hypothesis for this study was that catecholamine levels increase during urinary catheterization in human patients with spinal cord injury. Catecholamine levels, blood pressure, and pulse were measured prospectively in 40 subjects at baseline and during urinary catheterization. Results showed a significant increase in norepinephrine levels from baseline 245 +/- 240 pg (standard deviation (SD)) to 314 +/- 311 pg (SD) during catheterization (P = 0.018, Wilcoxon's). Results also showed a nonsignificant increase in epinephrine levels from baseline (56 +/- 70 pg, SD) to catheterization (84 +/- 125 pg, SD; P = 0.35, Wilcoxon's). Systolic blood pressure increased from 114 to 124 mm Hg (P = 0.004, paired t test). Diastolic blood pressure increased from 75 to 78 mm Hg (P = 0.11, paired t test). There was no significant change in diastolic blood pressure or pulse (P = 0.11 and P = 0.29, respectively, paired t test). In conclusion, norepinephrine levels increased during catheterization in patients with spinal cord injury. Knowledge of catecholamine levels in this process may assist in determining both pathophysiology and potential pharmacologic treatment options in future studies.

Abstract
Esophagogastrostomy covered by tongue-like sero-muscular flap of gastric wall has already been performed in 1515 cases with esophageal cancer of middle or lower third segment over the last three years. All cases were of squamous cell carcinoma. The same anastomotic procedure was done in all cases by authors in different hospitals. In this series the operative mortality was 0.07%, there were 5 anastomotic leaks (0.33%), and no anastomotic stricture and reflux esophagitis happened within 6 months to 3 years after surgery. The operative procedure is described again in detail. The authors believe that this new anastomotic procedure is satisfactory and prospectively beneficial for improving the therapeutic effect and patients' living quality after operation.

Abstract
The effect of mangiferin, a tetrahydroxy pyrrolidone saponin extracted from the leaves of mango (Mangifera indica), against herpes simplex virus type 2 (HSV-2) in vitro was studied. The 50% effective concentration (EC50) of it against HSV-2 plaque formation in HeLa cells was 111.7 micrograms.ml-1, and the concentrations of 33 and 80 micrograms.ml-1 reduced the virus replicative yields by 90% (EC90) and 99% (EC99), respectively. The therapeutic index (IC50/EC50) was 8.1. Mangiferin did not directly inactivate HSV-2. The results of the drug addition and removal tests suggest that mangiferin inhibits the late event in HSV-2 replication.

Abstract
Microcirculation and blood perfusion in unphysiological flaps were observed with rabbit ear microcirculation chamber. The microcirculation of the venous flap in two days after operation was reestablished mainly by diversion of blood flow through the "to and fro" movement of venous blood. Arteriovenous anastomoses were gradually opened, resulting in the microcirculation to restore normal perfusion, venous blood through the anastomoses into arteriole then to capillaries. The microcirculation of arterialized venous flaps was almost the same as that of the venous flaps. In two days after operation, the diversion of blood flow perfused the capillaries under high pressure, so that the flow velocity and rate were much faster and larger than those of the venous flaps. The microcirculation of venouslized arterial flap, nourished by venous blood through the arterial system, was the same as that of the physiological flap. But the capillaries were perfused venous blood flow, and the blood flow velocity and rate were much slower and smaller than those of the physiological flap.

Abstract
Cholecystokinin-octapeptide (CCK-8) of 10 ng were injected into lateral hypothalamus (LH) and ventromedial hypothalamus (VMH) in conscious rats, both of which brought about inhibition of antral motility recorded by a strain gauge, the actions were partly antagonised by bilateral vagotomy, but blocked by intravenous infusion of atropine or regitine. It is suggested that both vagus and sympathetic nerves be involved in mediation of function of central CCK-8. In addition, the unit spontaneous discharges of neurons in vagal nuclei were attenuated while CCK-8 injected into LH. On the contrary, the antral motility was stimulated markedly by injection CCK-8-antiserum into LH, indicating that the endogenous CCK-8 in this area exercises a continuous restraint on antral motility in the basal state. CCK-8 cells both in LH and VMH were visualized by PAP method. It may be reasonable to refer this as the histological basis of the identical function on antral motility exercised by CCK-8 both in LH and VMH.
