Objective To investigate the clinical effect of acupuncture therapy for ascending and descending Qi for the treatment of insomnia with the syndrome of liver stagnation. Methods Sixty quantified patients were randomized into 2 groups, 30 cases in each group. The patients in the treatment group were treated by acupuncture therapy for ascending and descending Qi, and the control group was given conventional acupuncture therapy. The polysomnography ( PSG) results and Pittsburgh sleep quality index ( PSQI) were compared before and after treatment, and the clinical efficacy was evaluated after treatment in the two groups. Results ( 1) The parameters of total sleep time, deep sleep time and rapid eye movement ( REM) time were prolonged, and the sleep latency and waking-up frequency in both groups were reduced after treatment (P<0.05 compared with those before treatment), and the improvement of total sleep time, deep sleep time and REM time in the treatment group was significantly superior to that in the control group (P<0.05). (2) PSQI scores in both groups were reduced after treatment ( P<0.01 compared with those before treatment) , and the reduction in the treatment group was more significant than that in the control group (P<0.01). (3) The total effective rate in the treatment group was 93.33%and was 76.67%in the control group. The efficacy in the treatment group was better than that in the control group (P<0.01). Conclusion Acupuncture therapy for ascending and descending Qi has better effect on insomnia with liver stagnation than conventional acupuncture therapy, being practical and innovative.

Objective To understand the effect of butylbenzyl phthalate(BBP) on the levels of DNA-protein crosslinks(DPC) in hepatic cells of mice.Methods Twenty-five male Kunming mice were randomly assigned into five groups(n=5).BBP was administered by intraperitoneal injection at doses of 0(control group),125,250,500,1 000 mg/kg respectively for 14 consecutive days.Then the levels of DNA-protein crosslinks were detected.Results DPC coefficient increased with concentration of BBP increasing.Treatments of 500 and 1 000 mg/kg BBP significantly increased the levels of DPC compared with the control group. Conclusion BBP can not cause DPC at low levels(125 mg/kg),but it can cause DPC significantly at high levels(500 and 1000 mg/kg),which may cause serious DNA damages.

The safflower floret is a traditional Chinese medicine used to promote blood circulation and remove obstruction in the channels. The spines on its bracts are considered a handicap when manual harvest is involved. In this study, cDNA-SRAP was used to systematically investigate which genes are associated with the spines. Sixty pairs of possible primer combinations were used on two cDNA pools representing spininess and spinelessness. Six transcript-derived fragments were identified, of which two with low recombination were sequenced successfully and named as GPY-1 and GPY-2. By using the RACE method, the full-length cDNA of GPY-2 is cloned and named as CTL-spn. The full-length cDNA of CTL-spn was 1 679 bp long with a 1 524 bp ORF encoding a 508 aminoacid protein. The deduced amino acid sequence of the CTL-spn gene shared a high homology (97%) with other known ATP synthase CF1 alpha subunits. Semiquantitative RT-PCR analysis revealed that the mRNA of GPY-1 and GPY-2 accumulated in only spiny lines. Considering the important role of ATP synthase CF1 alpha subunit in plants, it may directly take part in the formation process of spininess and enhancing resistance reaction of spiny safflower. Also, our results provide the important insights for breeding spineless cultivars of safflower.

Objective To evaluate the efficacy and safety of the conscious analgesia/sedation scheme with remifentanil and propofol on the elderly patients under gastroenterological endoscopic procedure. Methods Retrospective analysis was performed on 3 500 cases with remifentanil and small?dose propofol under gastroenterological endoscopic procedures, and the procedure achievement, effects of the narcotic, adverse reactions and satisfactory results were summarized. Results All procedures were completed successfully. The ratio of the patients whose intended sedation depth arrived at referential induction was up to 91?3%(3 196/3 500).Hemodynamic change was slight and almost all patients could open eyes in no time, with short hospital stay. No serious adverse effects were observed except several patients complaining about mild bucking, abdominal distension and stomachache. The degree of patients′ satisfaction was high. Conclusion The conscious analgesia/sedation scheme with remifentanil and propofol can be effectively and safely used on gastroenterological endoscopic procedure among the elderly, but precise monitor and timely treatment of complications are still needed.

A case with the diagnosis of the onset of inflammatory bowel disease (IBD) with chronic granulo-matous disease (CGD) in Children′s Hospital Affiliated to Zhengzhou University in June 2016 was chosen, and the patient′s clinical data and whole treatment process were analyzed.According to the relevant literature from Chinese and foreign databases, the clinical characteristics were analyzed and summarized, principles of diagnosis and treatment for children who had the onset of IBD with CGD.This patient was a child of 1 year and 9 months old, and the initial symptoms included repeated diarrhea and bloody stools.He was diagnosed as " ulcerative colitis" in the local hospital.After admission, the neutrophil respiratory burst test was positive.The genetic analysis result suggested that the CYBB gene was mutated, thus obtaining the diagnosis of CGD.Then, he was given prophylactic antibiotic therapy and symptomatic treatment.After the 3 months of follow-up after discharge, the patient still had intermittent diarrhea and bloody stools.CGD is a rare primary immunodeficiency disease, and current treatment methods of CGD include hematopoietic stem cell transplantation and anti-infection treatment.When IBD patients have complications other than gastrointestinal symptoms, the IBD treatment is not effective, or there are suspected parents who are married to close relatives, or with the family history of IBD, CGD should be considered.

Objective:To evaluate the effects of neuregulin-1 (NRG-1) pretreatment on diaphragmatic function in septic rats.Methods:Twenty-six clean-grade healthy adult male Sprague-Dawley rats, weighing 220-260 g, were divided into 3 groups using a random number table method: sham operation group (group S, n=6), sepsis group (group Sep, n=10) and NRG-1 group (group N, n=10). Sepsis was induced by cecal ligation and puncture in anesthetized rats.Group S underwent simple laparotomy.At 30 min before operation, recombinant human NRG-1β 10 μg/kg was injected through tail vein in group N, while the equal volume of normal saline was given in S and Sep groups.At 24 h after operation, the survived rats were sacrificed, and the diaphragm was removed for determination of the contractile function and contents of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) (by enzyme-linked immunosorbent assay) and for examination of the pathological changes (by hematoxylin and eosin staining). Results:Compared with group S, the force-frequency curve was shifted downward, and the levels of TNF-α and IL-6 were increased ( P<0.01), inflammatory cell infiltration was observed in Sep and N groups.Compared with group Sep, the force-frequency curve was shifted upward , and the levels of TNF-α and IL-6 were decreased ( P<0.01), inflammatory cell infiltration was alleviated in group N. Conclusion:NRG-1 pretreatment can improve diaphragmatic contractile function in septic rats, and the mechanism is related to reducing diaphragmatic inflammatory responses.

Objective To investigate the value of automatic spectral imaging mode selection and adaptive statistical iterative reconstruction(ASIR) in upper abdominal enhanced CT with low contrast agent dose, and to optimize the combination of monochromatic energy level and ASIR percentage.Methods 100 patients underwent upper abdominal enhancement CT were randomly assigned into control group (n=50) and study group (n=50).In the control group, tube voltage of 120 kVp and contrast medium of 450 mg I/kg were used with the images reconstructed using 40% ASIR.In the study group, CT spectral imaging with automatic spectral imaging mode selection and contrast medium of 300 mg I/kg were used,and monochromatic images (40-65 keV,intervals of 5 keV) were reconstructed using 40%-60% ASIR (intervals of 10%), respectively.CT value, image noise and contrast-to-noise ratio of the liver, pancreas, aorta and portal vein and radiation dose were compared using two independent samples t test.Overall image quality was assessed by Mann-Whitney U test.Results All image quality indexes in 60 keV with 40% ASIR, 55-60 keV with 50% ASIR in the study group were equal to or better than the control group.There was no significant difference in radiation dose between control group and study group.Conclusion Combined automatic spectral imaging mode selection with ASIR, upper abdominal enhanced CT with low contrast agent dose could improve image quality compared to 120 kVp with 40% ASIR, without increasing radiation dose.
