Objective: To investigate the changes of oxygen metabolic parameters and blood glucose concentrations during perioperative period of orthotopic liver transplantation. Methods: The blood gas, cardiac index (CI), mixed venous oxygen saturation (SvO2), oxygen delivery (DO2), oxygen consumption (VO2), oxygen extraction rate (O2ER), and arterial blood glucose were measured at defined time points (before anesthesia induction, 30 min before anhepatic period, 5 min after anhepatic period, 30 min after anhepatic period, 5 min of neohepatic period, 30 min of neohepatic period, and postoperation) in 50 patients receiving liver transplantation. Results: Compared with those before anesthesia induction, no significant changes in CI, SvO2, DO2, VO2, and O2ER were found in pre-anhepatic period. CI, VO2, and DO2 decreased significantly at the early 5 min of the anhepatic period (P<0.05); VO2, DO2, and O2ER decreased significantly at the 30 min of the anhepatic stage (P<0.05). SvO2, DO2, and VO2 increased, but O2ER decreased significantly at the early 5 min of the neohepatic stage (P<0.05). DO2, VO2, and O2ER increased significantly at the 30 min of the neohepatic stage (P<0.05). During preanhepatic stage the blood glucose levels increased progressively but were lower than those during anhepatic stage. During neohepatic stage, blood glucose decreased abruptly but was still higher than the normal level (P<0.05). Conclusion: It suggests that serious imbalance of oxygen metabolism exists during liver transplantation, especially in anhepatic and early neohepatic stages. Blood glucose increases during the preanhepatic stage, reaches the peak during the anhepatic stage, and then decreases gradually.

Objective To study the methods of clinic diagnosis and treatment for chronic lumbar pain induced by lumbo-sacral compartment syndrome. Methods Thirty-three patients with chronic lumbar pain induced by lumbo-sacral compartment syndrome were diagnosed by physical, radiological examination and intra lumbo-sacral muscle compartmental pressure measurement. 33 patients consisted of 15 men and 18 women, with the mean age 42.3 years, and mean duration of chronic lumbar pain was 27 years. Lumbar erector spinae osteo-facial compartment was decompressed using mini-invasive surgery. Lumbar and abdomen muscles were rehabilitated extensively after operation. Results After operation, symptoms of low back pain were alleviated significantly, and walking distance were promoted as well. Post operative flexion and extension of lumbar spine were increased to (15??0.5?) and (7??0.7?) respectively. Intramuscular pressure in rest state, during movement and no more than 6 min after movement was (6.8?0.8), (162.3?12.35) and (7.1?0.6) mm Hg respectively [before operation was(10.4?0.9), (187.1?11.16) and (13.2?1.3) mm Hg respectively, P

Objective To compare the efficacy of postoperative noninvasive positive pressure ventilation ( NPPV ) plus standard medical therapy ( SMT) with SMT alone in patients with moderate to severe chronic obstructive pulmonary disease ( COPD )Methods Twenty-four patients, after upper abdominal or thoracic surgery, who suffered from COPD and moderate to severe respiratory insufficiency, were randomly allocated to receiving SMT alone (oxygen, aminophylline infusion, nebulized beta-2 agonists and anticholinergics, antibiotics administration and chest physiotherapy; control group ,n=12) or NPPV in addition to SMT(NPPV group ,n=12) NPPV was intermittently given with an air-cushioned face mask under the continuous positive airway pressure of 3 cmH 2O and FiO2 of 35%Results There were not significant differences in baselines between both groups 8 patients in control group ( 667%) and all patients in NPPV group recovered with initial therapy with statistically significant difference (P

Objective To explore the effect of endoscopic sinus surgery on inverted papilloma of nasal cavity and paranasal sinuses in 30 cases.Methods 30 patients with inverted papilloma of nasal cavity and paranasal sinuses were operated on by endoscopic sinus surgery.Results During a follow-up of 2～3 years,only four cases recurred, Conclusion Endoscopic sinus surgery had advantsges of clear field and little injury,and therefore it was effective for inverted papilloma of nasal cavity and paranasal sinuses.

Objective To explore the effect of apolipoprotein E (ApoE) gene polymorphism on brain volume in healthy young adults.Methods One hundred and ninety-three healthy young volunteers (age:20-40 years) were recruited in Shengjing Hospital of China Medical University between August 2013 and May 2014.Two milliliters of peripheral blood were collected for the determination of ApoE genotype using direct sequencing of polymerase chain reaction (PCR) products.Brain MRI scans were performed using three-dimensional T1-weighted turbo field echo imaging sequence.The diffcrences of brain morphometry between the ε4 carriers group (ε3/ε4 and ε4/ε4 genotype) and the ε4 non-carriers group (ε3/ε3 genotype) were analyzed using voxel based morphometry (VBM).Results The ε4 carriers accounted for 14.51％ (28/193) of the total population.Twenty of ε4 carriers and 45 of ε4 non-carriers were included in the final images analysis.VBM analysis showed that the ApoE ε4 carriers had 10 atrophic brain areas compared with the ε4 non-carriers (P ＜ 0.005,uncorrected,10 continuous voxels),which mainly located in the right anterior cingulate,the bilateral caudates,parietal lobes and lateral temporal lobes.Conclusions The influence of ApoE gene polymorphisms on brain volume has appeared in the youth.The ε4 gene is related to the reductions of the gray matter volume in multiple brain areas.

[ ABSTRACT] AIM:To evaluate the clinical application of single nucleotide polymorphism array ( SNP array) in prenatal diagnosis for screening the abnormality of women with Down’ s syndrome ( DS) .METHODS:The amniotic fluid samples ( n=312) collected by amniocentesis for the DS screening abnormality women were tested by karyotyping and SNP array analysis, respectively.The findings of karyotyping and SNP array analysis were compared.RESULTS:Two cases of trisomy 21 were identified by karyotyping and SNP array analysis, but SNP array analysis failed to identify 6 cases of chro-mosome balanced structural rearrangement.SNP detected 176 cases copy number variants ( CNVs) in 303 cases normal karyotype were detected by SNP, including 106 benign CNVs, 61 variants of unknown significance (VOUS), 9 de novo CNVs, and none of them was pathogenic.The distribution difference of CNVs in DS screening positive group and DS screening positive plus advanced maternal age group was not statistically significant ( P>0.05) .Furthermore, we reported 14 kinds of CNVs for the first time in population.CONCLUSION:SNP array can further assure chromosome microdupli-cation/microdeletion.In normal karyotype fetus of prenatal diagnosis, SNP can detect some clinical significant CNVs.

Objective To find out the influencing behavioral factors of antibiotics usage in population in Lanzhou. Methods Status of antibiotics usage was investigated in four hospitals in Lanzhou. Results The self-medicine pro portion among patients with respiratory system infection, infectious di arrhea, urinary system infection and choleic system infection were 44.22%, 31. 76%, 22.07% and 6.61% respectively. Patients having higher income used some antibiotics at a middle price, while patients having lower income used antibiot ics at a lower price. The educate d person applied some antibiotics at a lower price, but the illiterate person us ed some antibiotics at a higher price. The combined usage of antibio tics was affected by the disease program and distance of seeing doctor. The fart her distance away from hospital, the more proportion of antibiotics(two or thre e) used combinedly. Conclusions The antibiotics usage was affe cted by the disease variety, disease program, distance to hospital, average inco me and educ ated level.

Type 2 innate lymphoid cells ( ILC2s) are recently identified members of the innate lymphoid cell ( ILC) family. These cells are capable of producing Th2-type cytokines such as IL-5 and IL-13 in response to epithelial cell-derived cytokines IL-25 and IL-33 and play critical roles in allergic diseases such as bronchial asthma. Further investigations on ILC2s will enhance the better understanding of type 2 immune responses and may provide new strategies for the treatment of allergic asthma. In this review, we fo-cus on the origin, location and biological function of ILC2s as well as their possible roles in the pathogenesis of bronchial asthma.
