A novel method for DNA detection was developed based on the excellent fluorescence properties of cationic conjugated polymer ( CCP)and the target DNA enrichment,separation function of nanoparticles. First,the quencher-labeled DNA capture probes were modified on the surface of Au nanoparticles,and complementary DNA strands were captured. Second,S1 nuclease was added,and the capture probes that had not captured the complementary DNA were removed from the nanoparticles.Finally,the complementary double-stranded DNA was cut by Dnase I,the quenchers were dissociated from nanoparticle and the fluorescence of CCP was quenched by means of combination of quenchers and CCP.The results showed that this method is specific.In the range of 5. 0 -40 nmol/L,the concentration of target DNA was proportional to the fluorescence quenching and the detection limit was 3.7 nmol/L(S/N = 3).

Objective To explore the risk of developing metabolic syndrome (MS) by using the data from cohorts involving people having received screening programs for physical check-up,in three areas of China (Beijing,Hongkong and Taiwan).Methods A total number of 6 828 non-metabolic syndromic adults,who received physical examination for the first time and with records kept for longer than 5 years (between 2004 and 2010) at the MJ centers,were recruited.Criteria developed by the Joint Committee for Developing Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Chinese Adults in 2007 (JCDCG-2007) was used for defining the metabolic syndrome.Cox proportional hazards regression model was used to examine the difference of the risk of developing MS among the three cohorts that received the health screening programs.Results The standardized incidence densities of MS were 3.14 per 100 person-years,2.19 per 100 person-years and 2.03 per 100 person-years in the cohorts of Beijing,Hongkong and Taiwan,respectively.After adjusting for gender,age,cigarette smoking,dietary patterns at the baseline,the HRs for people in Beijing and Hongkong were 1.60 (95％CI:1.34-1.91) and 1.08 (95％CI:0.83-1.41) respectively,in developing MS,when compared with people from Taiwan.Factors as being male,elderly,cigarette smoking,meat/food intake dietary pattern and MS components at the baseline all showed significantly positive effects on the risk of developing MS.Conclusions There were significant differences regarding the risk of developing MS among health screening people from the Beijing,Hongkong and Taiwan.Factors as being male,elderly,cigarette smoking,meat/food intake,dietary pattern and MS components at the baseline appear to be the risk factors for developing the MS.

Acute pancreatitis ( AP ) is one of the common disorders of gastrointestinal system in clinical practice characterized by sudden onset, long course of disease, complex complications, severe conditions, heavy social and economic burden and the like. Recent years has seen a decreasing mortality due to the update and promotion of a series of therapeutic concepts. However, as the imbalance of comprehensive healthcare levels among different regions in China, substandard diagnosis and treatment of AP still exist, lowering the overall success rate of AP treatment. Moreover, the waste and miss of AP patients' data during the treatment period affect our original innovation in the field of AP research. Thus, after the accumulation of long-term exploration and practice, we integrated diverse data resources and established a single-disease database of AP by cooperating with computer and artificial intelligence ( AI) professionals, finished the deployment of hardware and network arrangement, generated a logical system of "business database→scientific database→sharing database", and built AP data sharing platform (www. ap-database. com), providing the fundamental functions including browse, search, upload and download ( with permissions) . We hope to share the abundant and free medical date with clinicians, computer or AI practitioners and attract communications and cooperation from different fields, which may deepen new values from current data mining and advance the research on AP.

Objective:To investigate the protective effect of hypothermic antegrade machine perfusion against canine ischemic brain injury.Methods:Thirteen beagle dogs were divided into the mild hypothermia with perfusion group ( n=6) and normothermia with perfusion group ( n=7) according to the random number table. The model of ischemic brain injury was established by neck transection. After 1 hour of ischemic circulatory arrest, the perfusion fluid based on autologous blood was continuously perfused through bilateral common carotid artery for 6 hours. The temperature of the perfusion fluid was set at 33 ℃ in the mild hypothermia with perfusion group and 37℃ in the normothermia with perfusion group, respectively. Blood oxygen saturation was recorded at 0, 1, 2, 3, 4, 5 and 6 hours after the beginning of perfusion to evaluate the perfusate oxygen level. The perfusate was collected, and the levels of Na +, K +, Ca 2+ and glucose as well as the pH value of the perfusate were detected in the two groups. At the end of perfusion, the parietal brain tissues of 1 dog from each group were collected to evaluate the water contents of brain tissues. Nissl staining was used to evaluate the morphological integrity of the pyramidal neurons in the frontal cortex and hippocampus. Neuronal nuclei antigen (NeuN) was used to evaluate the structural and morphological integrity of pyramidal neurons. Immunofluorescence glial fibrillary acidic protein (GFAP) and ionic calcium binding adaptor molecule 1 (Iba1) were used to evaluate the integrity and activity of astrocytes and microglia fragments. Results:At 0, 1, 2, 3, 4, 5 and 6 hours of perfusion, there was no significant difference in the blood oxygen saturation or Na + concentrations between the two groups (all P>0.05); the K + concentrations in the mild hypothermia with perfusion group were (4.57±0.12)mmol/L, (4.67±0.14)mmol/L, (4.27±0.12)mmol/L, (4.45±0.10)mmol/L, (6.60±0.15)mmol/L, (7.37±0.18)mmol/L and (9.03±0.16)mmol/L, respectively, which were significantly lower than those in the normothermia with perfusion group [(4.84±0.10)mmol/L, (5.31±0.13)mmol/L, (5.44±0.24)mmol/L, (5.70±0.18)mmol/L, (7.79±0.18)mmol/L, (10.44±0.40)mmol/L, (10.40±0.41)mmol/L] (all P<0.01). At 0, 1, 2 and 3 hours of perfusion, the Ca 2+ concentrations in the mild hypothermia with perfusion group were (0.72±0.15)mmol/L, (1.55±0.16)mmol/L, (1.62±0.15)mmol/L and (1.88±0.15)mmol/L, respectively, being significantly higher than those in the normothermia with perfusion group [(0.41±0.13)mmol/L, (0.99±0.12)mmol/L, (1.29±0.13)mmol/L, (1.57±0.11)mmol/L] (all P<0.01), and no significant differences were found at other time points (all P>0.05). At 0, 1 and 2 hours of perfusion, the glucose concentrations in the mild hypothermia with perfusion group were (5.75±0.19)mmol/L, (5.17±0.15)mmol/L and (4.72±0.15)mmol/L, respectively, being significantly higher than those in the normothermia with perfusion group [(5.30±0.22)mmol/L, (4.89±0.20)mmol/L, (4.30±0.17)mmol/L] (all P<0.01), with no significant differences found at other time points (all P>0.05). At 2, 3, 4, 5 and 6 hours of perfusion, the pH values of the mild hypothermia with perfusion group were 7.32±0.06, 7.25±0.02, 7.23±0.02, 7.24±0.02 and 7.24±0.02, respectively, being significantly higher than those in the normothermia with perfusion group (7.26±0.01, 7.21±0.01, 7.17±0.02, 7.15±0.02, 7.08±0.02) ( P<0.05 or 0.01), with no significant differences at other time points (all P>0.05). The water content of brain tissues in the mild hypothermia with perfusion group was (74.9±0.4)%, which was significantly lower than (79.9±0.9)% in the normothermia with perfusion group ( P<0.01). Nissl staining showed that the pyramidal neurons in prefrontal cortex and dentate gyrus had good integrity in the mild hypothermia with perfusion group. NeuN immunofluorescence staining showed that the morphology and structure of pyramidal neuron cells in the mild hypothermia with perfusion group were better with clearly visible axons than those in the normothermia with perfusion group, whereas the cytosol was full and swollen with scarce axons in the normothermia with perfusion group. GFAP and Iba1 immunofluorescence staining showed that more structurally intact glial cells, more abnormally active cells, thickener axons and better axon integrity in all directions were found in the mild hypothermia with perfusion group than those in the normothermia with perfusion group. Conclusion:Compared with normal temperature antegrade mechanical perfusion, the mild hypothermia antegrade mechanical perfusion can protect canine brain tissue and alleviate ischemic brain injury by maintaining stable energy and oxygen supply, balancing ion homeostasis and perfusion fluid pH value, reducing tissue edema, and maintaining low metabolism of pyramidal neurons, astrocytes and microglia.

Objective To summarize the experience and practical value of living donor kidney harvesting in Bama miniature pigs with six gene modified. Methods The left kidney of Bama miniature pigs with six gene modified was obtained by living donor kidney harvesting technique. First, the ureter was occluded, and then the inferior vena cava and abdominal aorta were freed. During the harvesting process, the ureter, renal vein and renal artery were exposed and freed in sequence. The vascular forceps were used at the abdominal aorta and inferior vena cava, and the renal artery and vein were immediately perfused with 4℃ renal preservation solution, and stored in ice normal saline for subsequent transplantation. Simultaneously, the donor abdominal aorta and inferior vena cava gap were sutured. The operation time, blood loss, warm and cold ischemia time, postoperative complications and the survival of donors and recipients were recorded. Results The left kidney of the genetically modified pig was successfully harvested. Intraoperative bleeding was 5 mL, warm ischemia time was 45 s, and cold ischemia time was 2.5 h. Neither donor nor recipient pig received blood transfusion, and urinary function of the kidney transplanted into the recipient was recovered. The donor survived for more than 8 months after the left kidney was resected. Conclusions Living donor kidney harvesting is safe and reliable in genetically modified pigs. Branch blood vessels could be processed during kidney harvesting, which shortens the process of kidney repair and the time of cold ischemia. Living donor kidney harvesting contributes to subsequent survival of donors and other scientific researches.

OBJECTIVE：To investigate the pharmaceutical ca re for a child with refractory Stenotrophomonas maltophilia sepsis by clinical pharmacists ，and to provide reference for the treatment of children with this disease. METHODS ：Clinical pharmacist participated in drug therapy for a child with refractory S. maltophilia sepsis. Based on the pathophysiological characteristics of the child and the PK/PD characteristics of the antimicrobials ，clinical pharmacists suggested that the anti-infection regimen should be adjusted as cefoperazone sodium and sulbactam sodium 160 mg/（kg·d），every 8 hours combined with levofloxacin 10 mg/kg， every 12 hours. For clinical manifestations of severe inflammatory reaction ， the clinical pharmacist suggested receiving methylprednisolone sodium succinate 1 mg/kg additionally ，every 12 hours，for anti-inflammatory adjuvant therapy. At the same time， clinical pharmacist provided individualized pharmaceutical care （including the detection of blood concentration of cefoperazone sodium and sulbactam sodium ，the detection of ADR and medication education of oxygen atomization ）during the treatment，and followed up the child for one year. RESULTS ：The doctors adopted the suggestions of clinical pharmacists. The sepsis was controlled ，the child ’s condition were improved and then discharged. During the follow-up ，the child did not suffered from ADR ，such as cartilage and joint injury. CONCLUSIONS ：Hypoimmunity，long stay in intensive care unit ，endotracheal intubation and malignant tumor are the high risk factors of S. maltophilia infection. The monitoring of therapeutic drugs of cefoperazone sodium and sulbactam sodium is very necessary in the treatment of severe infection in children. After weighing the advantages and disadvantages and meeting certain conditions ，children can use quinolones for anti-infection ；based on the effective anti-infection treatment ，low-dose glucocorticoid can reduce the systemic inflammatory respense in patients with sepsis.
