Objective To study the exocrine pancreatic function in critically ill children with septic shock,sepsis and hyperlactacidemia.Methods A total of 64 critical pediatric patients were admitted from Jan 2009 to Oct 2012,and clinical and laboratory findings including pancreatic function,and histopathological features and score after autopsy were reviewed.Results (1) Compared with non-septic shock children,the pancreatic pathology score and serum lipase in septic shock group were significantly higher and serum calcium was significantly reduced (P ＜0.05) ; (2) The pancreatic histopathology score was significantly increased in patients with elevated plasma lactate ≥2 times (P ＜0.05),but there were no significant differences in serum calcium and blood amylase and lipase between patients with elevated plasma lactate level and patients with normal plasma lactate level; (3) The concentrations of serum amylase,lipase and urinary amylase were significantly increased in patients with pancreatic histopathology score ＞4 points compared with score ≤4 points patients,but there were no significant differences in above three biomarkers between patients with score ≤3 points and patients with score ＞3 points.Conclusions The pancreas is vulnerable to damage easily occurred in septic shock children especially complicated with hyperlactacidemia.The pancreatic histopathology score ＞ 4 points can be as a sensitive and reliable indicator of pancreas damage.

OBJECTIVETo screen the regulatory proteins involved in Nox1 promoter activation in a cell model of inflammation and oxidative stress.

METHODSA cell model of inflammation and oxidative stress was established by stimulating A549 cells with tumor necrosis factor-α (TNF-α). The differential proteins binding to Nox1 promoter were screened by DNA pull-down and the binding proteins were separated by 2D electrophoresis and selected according to the their differential expression levels (with over 1.5-fold changes relative to the control level). The screened proteins were finally identified by MALDI-TOF/TOF-MS.

RESULTSSeven differentially expressed protein spots (all upregulated in the cell model) were obtained, among which GLE1, DDX19A, KRT1 and KRT10 were identified by mass spectrometry.

CONCLUSIONGLE1, DDX19A, KRT1 and KRT10 participate in the activation of Nox1 promoter in TNF-α-induced A549 cells, and this result provides new insights into the biological roles of the regulatory proteins of Nox1 promoter in inflammation and oxidative stress.

An old male patient visited the hospital due to shortness of breath and palpitation for 6 h, with fever 3 days before and pump failure at admission. Having no risk factor of coronary diseases such as hypertension, diabetes mellitus and obesity, with ST-T changes and abnormal Q wave on ECC, the signs were compatible with those of acute anterior wall myocardial infarction, while the characteristics of cardiac biomarkers ( significant increase in Troponin I and creatine kinase's isoform, and normal creatine kinase) were not in accordance with those of acute myocardial infarction. Emergency angiography was performed, which indicated normal coronary artery, normal pulmonary artery and global systolic dysfunction of left ventricle. The diagnosis of acute severe myocarditis was established, and intra-aortic balloon pump (IABP) was employed to provide hemodynamic support. Severe myocarditis mimicking acute myocardial infarction may be fatal, and can be easily misdiagnosed. Careful analysis of clinical manifestations, early diagnostic angiography and possible IABP placement are important for the successful treatment.

Identification of genetic risk factors is the hotspot of adolescent idiopathic scoliosis (AIS). Through candidate gene approach and genome-wide association studies (GWAS), some genes were preliminary identified. To review AIS related genes,and construct the gene network map of AIS gene. We searched on NCBI PubMed and Web of Science database using search terms "adolescent idiopathic scoliosis" and "gene", to classify induction genes. We then constructed gene diagram using string-db. We found 35 AIS genes relating to connective tissue, nervous system active substances, melatonin synthesis and metabolism, puberty and growth, and genes whose function is unknown. Gene diagram shows that a network relationship between gene and other genes,in which IL6, ESR1, ESR2, VDR, TGFB1, IGF1 gene may as the key gene about AIS' genetic mechanism. Two sites of 3 GWAS results outside the network, it is suggesting new pathway that need to be explored. The study about AIS susceptibility gene is still preliminary, requiring in-depth research to identify the new networks.

Objective To evaluate the relationship between preoperative MRI characteristics and the perioperative outcomes of microvascular decompression in primary trigeminal neuralgia. Methods To analyze the relationship between preoperative MRI characteristics and the perioperative outcomes in 103 primary trigeminal neuralgia patients with micro-vascular decompression in Nanfang Hospital. The MRI features such as the ratio of CPA area, TGN cross-sectional area and TGN length was evaluated together with the TGN oppression distance, the position of TGN, the position of basilar ar-tery and the type of offending vessel as well as the outocmes including complete disappearance, temporary remission and ineffectiveness. Results Univariate analysis showed that the oppression orientation (P=0.017), oppression distance (P<0.001), offending vascular type (P=0.016), TGN cross-sectional area ratio (P<0.001) were the influencing factors of periop-erative outcomes. Logistic regression analysis showed that the offending vascular type (P=0.002)and TGN cross-sectional area ratio (P=0.020) were the main predictive factors of perioperative outcomes of microvascular decompression. Conclu-sions Preoperative thin slice MRI scanning showed that the offending artery, non-atrophy nerve roots, far distance from op-pression point to brainstem may be the favorable factors of perioperative outcomes of microvascular decompression.

Nerve injury produces a long lasting neuropathic pain, manifested as allodynia, a decrease in pain threshold and hyperalgesia, an increase in response to noxious stimuli. The mechanism underlying the lasting abnormal pain is not well understood. Our previous works have shown that electrical tetanic stimulation of the sciatic nerve induces long-term potentiation (LTP) of C-fiber evoked field potentials in the spinal dorsal horn, which is considered as a synaptic model of pathological pain. In the present study we tested if nerve injury, which is proved to produce neuropathic pain, induced the spinal LTP in intact rats. C-fiber evoked field potentials in spinal dorsal horn produced by electrical stimulation (10-20 V, 0.5 ms, 1/min) of the sciatic nerve were recorded. For induction of LTP of C-fiber evoked field potentials, three types of noxious stimuli were applied. (1) Electrical tetanic stimulation (40 V, 0.5 ms pulses at 100 Hz for 1 s repeated four times at 10 s intervals). (2) Transection of the sciatic nerve at 4-5 mm distal to the stimulation electrode. (3) Crushing the sciatic nerve with a forceps four times at 4-5 mm distal to stimulation electrode (from distal to proximal with 1 mm spacing at 10 s intervals), which simulated electrical tetanic stimulation. Acute nerve injury was made by either transection of the sciatic nerve at the distal to the stimulating electrode or crushing the sciatic nerve. We found that nerve injury by cutting or crushing the sciatic nerve produced LTP of C-fiber evoked field potentials lasting until the end of the experiments (3-9 h), and that pretreatment of the sciatic nerve with lidocaine 10 min prior to the nerve transectoin completely blocked LTP induced by nerve transection. The nerve transection-induced LTP was blocked by NMDA receptor antagonist AP5. LTP produced by nerve transection could not be further potentiated by electrical tetanic stimulation, while LTP induced by single electrical tetanic stimulation could be further potentiated by transection of the sciatic nerve. However, when LTP was saturated by several times of electrical tetanic stimulation, nerve transection did not affect the spinal LTP. We conclude that acute nerve injury induces LTP of C-fiber evoked field potentials in intact animals and that nerve transection is more powerful than electrical tetanic stimulation for induction of the spinal LTP. The results further support the notion that LTP of C-fiber evoked field potentials may underlie neuropathic pain.
