The research reviews the purpose, significance and indwelling method of indwelling nasal jejunum in critically ill patients with neurosurgery in recent years and It also studies the effects of indwelling on organ function. For example, improving pulmonary ventilation function can reduce the mechanical ventilation time of patients with mechanical ventilation; can effectively promote intestinal tissue and function, reducing electrolyte disturbance;and long-term catheter can affect the liver function, the occurrence of gastric retention, diarrhea, obstruction of the pipeline and the related complications. The authors hope to provide a reference for the clinical care. At present, the use of nasal jejunum is the trend of enteral nutrition in critically ill patients with neurosurgery, but the replacement time of nasal jejunum tube, oral care and other related complications are lack of corresponding research.

Objective To investigate the characteristic of autoantibodies of M-type phospholipase A2 receptor (PLA2R) in serum and the glomerular IgG subclass deposits in undetermined atypical membranous nephropathy (MN) patients.Methods From Feb 2004 to Nov 2011,53 cases diagnosed as MN by kidney puneture biopsy in our hospital were included into the study.There were 20 undetermined atypical membranous nephropathy (UAMN),20 idiopathic membranous nephropathy (IMN) and 13 secondary membranous nephropathy (SMN) which were composed of lupus membranous nephropathy (LMN) and HBV related membranous nephropathy (HBV-MN).Clinlical and pathological characteristics were analyzed.The autoantibodies of PLA2R in serum were detected and the glomerular IgG subclass deposits were observed.Results (1) The average age underwent renal biopsy was (37.9±3.8) years of UAMN,(50.1±3.0) years of IMN and (49.5±4.5) years of SMN.The difference in onset average age at disease was significant between UAMN and IMN (P =0.0178).The female/male ratio (F/M) in UAMN,IMN and SMN was 0.8∶ 1,0.7∶1 and 0.6∶ 1(P ＞ 0.05).(2) Compared with SMN,the level of 24-hours urinary protein excretion (3.47 g vs 7.89 g,P =0.023),the ratio of amount urinary protein patients (50.0％ vs 84.6％,P=0.043),the level of serum IgG [(8.40±3.58) g/L vs (10.09±4.69) g/L,P =0.025] and the positive rate of ANA in serum (10.0％ vs 53.8％,P =0.006) in UAMN were all much lower.There were no significant statistical differences in serum albumin,serum creatinine,eGFR,positive rate of HBsAg,HBeAg or HCV,as well as the ratio of hypo-albuminemia and nephrotic syndrome among the three groups.(3) IF positive rate of IgA,IgM and C1q in UAMN were all significantly higher than that in IMN (P ＜ 0.01).There were no significant differences in IF positive rate of IgA,IgM,C1q,IgG and C3 between UAMN and SMN.The IF strength of IgA,IgG,IgM,C3 and C1q in UAMN showed no significant differences between UAMN and SMN.(4) The serum autoantibodies of PLA2R were only detected in 10 cases of IMN group (50％) with all the other cases negative.This detection rate of serum autoantibodies of PLA2R showed significant statistical differences among the three groups (P ＜ 0.01),but no differences between UAMN and SMN (the detection rate in both groups were 0％).(5) IgG1 deposits was the dominant IgG on the glomeruli in UAMN group (40％),as well as in SMN group (76.9％).IgG4 deposits was the dominant IgG on the glomeruli in IMN group (60％).The positive rate of IgG1 and IgG3 in UAMN showed no significant statistical differences when compared with IMN or SMN.The positive rate of IgG2 in UAMN was significantly lower than in SMN (30.0％ vs 69.2％,P ＜ 0.05).The positive rate of IgG4 in UAMN was significantly lower than in IMN (20％ vs 60％,P ＜ 0.05).The positive rate of IgG1,IgG2 and IgG3 in SMN were all significantly higher than in IMN.Conclusions None of the UAMN group had autoantibodies of PLA2R in serum,and IgG1 deposits was the dominant IgG subclass on the glomeruli which indicated the similarity with the SMN group.At the same time,UAMN was significantly different from SMN in clinical manifestations.

Objective To investigate the expression of human leucocyte antigen-G (HLA-G) in the endometrium of patients with endometriosis (EM). Methods The expression of HLA-G protein was detected in ovarian endometriosis (OEM) and adenomyosis (AM) using immunohistochemistry method, and the expression of HLA-G mRNA was detected using in situ hybridization technique (ISH), to compare with that in the endometrium of hysteromyoma as the control group. Results The rate of positive HLA-G expression in EM (including AM and OEM) was significantly higher than that in control group (P0.05). The expression of HLA-G protein showed no relation with different clinical phase or different endometrial cycle. Conclusion HLA-G is overexpressed in EM, which may play certain role in the pathogenesis of the disease.

In order to investigate the comprehensive quality differences of the seeds harvested in different growing time, and offer theoretical guide for the optimization of seeds' production technology, we analyzed the apparent size, 1 000-grain weight, water absorbency, germination indexes, postharvest embryo rate change, relatively contents of coumarins and the yield of single plant of its seeds of different harvesting time, and compared their comprehensive quality by Topsis analysis. The results showed that there existed obvious differences in yield and quality between seeds of 3 harvesting times. While the harvesting time postponed, the yield of single plant raised, and the shrunken seeds rate decreased, the quality of seedlings increased, while the contents of coumarins showed a steady increase, and the germination rate decreased. The comprehensive quality of the seeds harvested in the black ripe time rank the first place, followed by the brown ripe time and the yellow ripe time. As the harvesting time delays, the seeds' comprehensive quality increases, therefore, we could put off the seeds' harvesting time properly for the high efficient seed production.

Objective To investigate the pathophysiological distinction of the functional connectivity between right temporal parietal junction(rTPJ) and whole brain in children with attention-deficit/hyperactivity disorder(ADHD) on resting-state functional magnetic resonance imaging(fMRI) and explore the neurological mechanisms of ADHD at the point of functional connectivity.Methods Resting-state functional magnetic resonance imaging scans were obtained in 30 children with ADHD from The Third Affiliated Hospital of Soochow Univcrsity and another 33 with age and gender matched controls from a normal primary school over the same period, and then,blood oxygenation level dependent(BOLD) signal was acquired to calculate the functional connectivity of rTPJ with other brain regions.Significant differences of connectivity intra-class and between groups were analyzed.Also, the correlation between the connectivity strength and the ADHD rating scales were tested.Results The pattern of functional connectivity of the rTPJ for the ADHD group was similar to that of the normal control group.Compared with the normal controls, the left superior temporal gyrus (MNI coordinates-33,6,48) , the right anterior c ingulate coltex(MNI coordinates 6,39,-3) , the right inferior parietal lobule (MNI coordinates 42,-33,30) , the left medial frontal gyrus(MNI coordinates-3,63,-18) in children with ADHD sbowed an increased resting-state functional connectivity with the whole brain ,while the right middle temporal gyrus(MNI coordinates 57,-33,-12) , the right cingulate gyrus(MNI coordinates 18,-21,36) showed a decreased resting-state functional connectivity with the whole brain.The average connection strength between the rTPJ and the whole brain showed positive correlation with the ADHD scores,while in normal controls,it showed negative.The connection strength between the rTPJ and those 6 brain areas with significant statistical difference was relevant to the ADHD scores,but they had no statistical significance.Conclusion The functional connection abnormalities between tbc rTPJ and the whole brain in children with ADHD may be relevant to the clinical symptom of attention-deficit.

A novel, simple and highly sensitive method was developed for the rapid analysis of phenolic antioxidants at trace level in edible oils. It was based on dispersive liquid-liquid microextraction ( DLLME ) and gas chromatography-mass/mass spectrometry ( GC-MS/MS) . Related important factors that may influence enrichment efficiency, such as type and volume of extraction solvent, type and volume of dispersive solvent, and extraction time were investigated and optimized in detail. The optimum conditions were as follows:a quick injection of 500 μL mixed solution ( methanol:acetonitrile=1:1 , V/V ) into 1 . 0 g oil sample with 3 mL n-hexane for 10 s of extraction time. Under the optimal conditions, the linearity (10-2000 ng/g), limits of detection (1. 5-2. 4 ng/g) and relative standard deviations (4. 0%-8. 3%) was obtained. The proposed method was applied for the analysis of 4 edible oil samples. Some of phenolic antioxidants were detected in three of them, and the recoveries of spiked samples were in the range of 81. 9%-118%.

BACKGROUND: Orotracheal intubation with conventional Macintosh laryngoscope often makes strong alterations in hemodynamic responses. Compare with the Macintosh laryngoscope, the Airtraq~((R)) laryngoscope has weak effect on throat irritation. However, the contrast effect on hemodynamics remains still unknown. OBJECTIVE: To compare the hemodynamical responses to orotracheal intubation between Airtraq~((R)) laryngoscope and Macintosh laryngoscope. DESIGN, TIME AND SETTING: A randomized comparative observation was performed at Department of Anesthesiology, Dalian Second People's Hospital between October 2008 and April 2009. PARTICIPANTS: A total of 40 patents scheduled for surgery under general anesthesia requiring orotracheal intubation were randomly divided into Airtraq~((R)) laryngoscope group and Macintosh laryngoscope group, with 20 cases in each group. METHODS: After standard intravenous anesthetic induction, orotracheal intubation was performed with Airtraq~((R)) laryngoscope or Macintosh laryngoscope. Common Airtraq~((R)) laryngoscope was used in the Airtraq~((R)) laryngoscope group, and an endotracheal tube with internal diameter of 8.0 was inserted. No. 3 lens were used in the Macintosh laryngoscope group, and an endotracheal tube with internal diameter of 8.0 was inserted. MAIN OUTCOME MEASURES: Glottic exposure time, tracheal intubation time, noninvasive heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) before (T0) and after (T1) anesthetic induction as well as at 0 minute (T2), 1 minute (T3), 2 minutes (T4), and 3 minutes (T5) after intubation, as well as rate-pressure product (RPP). RESULTS: The glottic exposure time in Airtraq~((R)) laryngoscope group was significantly longer than that in Macintosh laryngoscope group (P < 0.01), while the tracheal intubation time in Airtraq~((R)) laryngoscope group was significantly shorter than that in Macintosh laryngoscope group (P < 0.01). Compared with pre-induction (T0), the SBP, DBP, and RPP of the two groups decreased significantly after anesthetic induction (T1) (P < 0.05), but the HR did not change remarkably (P > 0.05). Compared with T1, all hemodynamical values at T2, T3, T4 and T5 in Airtraq~((R)) laryngoscope group did not increased sign ificantly (P > 0.05). In Macintosh laryngoscope group, HR and RPP at T4, SBP, DBP, HR and RPP at T2 and T3 increased significantly compared with T1 (P < 0.05). In Macintosh laryngoscope group, HR and RPP at T2, T3 and T4 were significant higher than that in Airtraq~((R)) laryngoscope group (P< 0.05). CONCLUSION: In comparison to the Macintosh laryngoscope, tracheal intubation with the Airtraq~((R)) laryngoscope resulted in less alterations in hemodynamical responses.
