Objective:To investigate the clinical efficacy of psychotherapy combined with auricular plaster therapy in the auxiliary treatment of insomnia caused by liver fire disturbance in a sub-healthy population.Methods:Eighty sub-healthy patients with insomnia caused by liver fire disturbance who received treatment in Wenzhou Hospital of Traditional Chinese Medicine from June 1, 2017 to December 31, 2018 were included in this study. These patients were randomly assigned to receive cognitive behavioral therapy (control group, n = 40) or cognitive behavioral therapy combined with auricular plaster therapy (observation group, n = 40) for 4 weeks. Polysomnography was used to evaluate the sleep condition before and after treatment. The Pittsburgh Sleep Quality Index was used to evaluate the severity of insomnia. The World Health Organization Quality of Life Scale Brief Version (WHOQOL-BREF) was used to evaluate the quality of life of patients. The therapeutic effect was compared between the two groups. Results:After treatment, total sleep time [(421.25 ± 11.58) min vs. (456.25 ± 11.23) min], sleep efficiency [(70.32 ± 4.44)% vs. (76.58 ± 5.89)%], non-rapid eye movement stage 2 (N2) sleep [(43.25 ± 4.44)% vs.(45.62 ± 4.36)%], N3 sleep [(14.25 ± 4.52)% vs. (18.52 ± 5.55)%], rapid eye movement (R) sleep [(21.98 ± 5.21)% vs. (24.66 ± 4.87)%] in the control group were significantly shorter or lower than those in the observation group ( t = 13.723, 5.367, 9.035, 2.408, 3.772, 2.376, all P < 0.05). After treatment, sleep quality [(1.85 ± 0.54) points vs. (1.10 ± 0.42) points], sleep-onset latency [(1.52 ± 0.51) min vs. (1.08 ± 0.35) min], sleep duration [(1.30 ± 0.41) min vs. (0.75 ± 0.41) min], sleep efficiency [(1.53 ± 0.44) points vs. (1.02 ± 0.33) points], sleep disturbance [(1.20 ± 0.41) points vs. (0.78 ± 0.31) points], hypnotics [ (0.11 ± 0.02) points vs. (0.04 ± 0.01) points], daytime dysfunction [(1.65 ± 0.47) points vs. (1.03 ± 0.28) points] and total scores [(9.11 ± 1.33) points vs. (5.80 ± 1.01) points] in the control group were significantly higher than those in the observation group ( t = 6.933, 4.499, 5.999, 5.864, 5.167, 19.789, 7.167, 12 535, P < 0.05). After treatment, the scores in physical health [(13.85 ± 2.22) points vs. (17.86 ± 2.01) points], psychological domain [(15.52 ± 1.89) points vs. (16.35 ± 1.33) points], social relationships [(16.01 ± 1.58) points vs. (19.52 ± 1.85) points] and environment domain [(17.52 ± 1.90) points vs. (20.89 ± 2.22) points] in the control group were significantly lower than those in the observation group ( t = 8.468, 4.499, 9.124 and 7.294, all P < 0.05). After treatment, total effective rate in the observation group was significantly higher than that in the control group [95.0% (38/40) vs. 72.5% (29/40), χ 2 = 7.440, P < 0.05]. Conclusion:Psychotherapy combined with auricular plaster therapy can significantly increase the sleep duration and sleep efficiency and improve the quality of life of sub-healthy patients with insomnia caused by liver fire disturbance, which is worthy of clinical promotion.

The hemodynamic effects of deliberated hypotension induced by PGE1 or SNP on 14 dogs anesthetized by ketamine were studied separately.MAP was decreased by 30%~40% after infusing PGE,or SNP Hemodynamic variables were measured before and 15 min 30 min after hypotension and 15 min after the discontinuation of infusion.The results indicated that SVRI, PVRI, MPAP, LVSWI and RVSWI all decreased significantly during PGE1-or SNP-induced hypotension. CVP decreased and HR increased significantly during SNP-induced hypotension, but with no significant change during PGE1-induced hypotension and with SVI. CI. PCWP remained unchanged in these two groups throughout the experiments.

BACKGROUND:Ghrelin is a newly discovered brain-gut peptide from the stomach of human and rats. As an endogenous ligand for growth hormone secretagogue receptor (GHSR), ghrelin can notably stimulate the release of growth hormone. Although GHSR is expressed in many peripheral tissues, little is known about the influence of ghrelin on bone metabolism and GHSR expression in bone tissue. OBJECTIVE:To review the research progress of ghrelin in bone metabolism.METHODS:The first author retrieved CNKI, WanFang, PubMed, and Springerlink databases with the keywords ofGhrelin, bone metabolismin Chinese and English, respectively. The studies regarding ghrelin and its involvement in bone metabolism were included, and repetitive ones were excluded. A total of 53 eligible literatures were selected through skimming abstracts. RESULTS AND CONCLUSION:Ghrelin is a peptide composed of 28 amino acids discovered in gastric endocrine cells and hypothalamic arcuate nucleus in mice and human, which makes a great effect on digestive, nervous, immune and endocrine systems, and also plays a role in hormone secretion, glucose metabolism, immunity, cell proliferation, and inflammation. Serum ghrelin makes a certain influence on bone growth and development, and promotes the differentiation and proliferation of osteoblasts, and inhibits its apoptosis. Additionally, ghrelin suppresses the early osteogenic differentiation of C3H10T1/2 cells by upregulating the expression of Runx2 protein, and attenuates adipogenic differentiation by downregulating PPARγ2 expression, thus inducing osteogenic differentiation. However, few studies have addressed the expression of GHSR in bone tissue.

Objective To construct an RNA interference vector to down-regulate X-linked inhibitor of apoptosis(XIAP)gene and study the RNA interference effect on the cell cycle and growth of ovarian cancer.Methods Oligonucleotides of 64 base pairs for hairpin RNA targeting XIAP were designed, chemically synthesized,annealed,and cloned into the pSUPER vector.After identification by restriction digestion,the correct vectors were transiently transfected into SKOV3 cells,a human ovarian cancer cell line.The XIAP mRNA was detected by RT-PCR.The proteins were detected by western blot and indirect immunofluorescence staining.Flow cytometry(FCM)analysis and methyl thiazolyl tetrazolium(MTT)assay method were applied to measure cell cycle,cell growth and sensitiveness to cisplatin.Results SKOV3 cells had a high level expression of XIAP.The vector of RNA interference,which can interfere with XIAP gene was successfully constructed.After transient transfection,the expression of XIAP protein was significantly decreased in SKOV3 cells and the value of relative density was 3584?124,2138?65,1973?80 and 110 ?12,respectively(P=0.0334).At the same time,the expression of XIAP mRNA was decreased accordingly and the value of relative density was 6674?274,4532?107,2322?57 and 1864?78, respectively(P=0.0127).The FCM results showed that,the vector could increase the number of cells in G_1 phase compared with parent cells and compared with the cells transfected with pSUPER(P

Objective:To explore the distribution characteristics of respiratory pathogens in patients with community-acquired pneumonia in Lianyungang.Methods:A total of 612 patients admitted to the second people′s Hospital of Lianyungang City because of community-acquired pneumonia (CAP) in 2019 were selected as subjects. Sputum or pharyngeal swabs were collected to extract nucleic acids, and 13-fold nucleic acids of respiratory pathogens were detected by PCR capillary electrophoresis fragment analysis. SPSS statistical software and GraphPad5.0 statistical mapping software were used for statistical analysis.Results:The physical examination rate of respiratory pathogens in the adult group was 82.0% in winter, 48.4% in spring, 28.0% in autumn, 20.0% in summer, χ 2=38.473, P=0.000. The positive rate of nucleic acid detection was significantly different in different seasons, among which the physical examination rate of respiratory pathogens in winter was the highest. The physical examination rate of respiratory pathogens in the juvenile group was 86.0% in spring, 76.2% in winter, 71.3% in summer and 66.7% in autumn, χ 2=7.946, P=0.047 . The positive rate of nucleic acid detection was calculated according to gender grouping. The comparison of nucleic acid positive rate between adult group and juvenile group in different seasons: 86.0% vs 48.4% in spring, χ 2=19.436, P=0.000; 71.3% vs 20.0% in summer, χ 2=22.180, P=0.000; 66.7% vs 28.0% in autumn, χ 2=13.485, P=0.000; 76.2% vs 82.0% in winter, χ 2=0.758, P=0.384. Except in winter, the detection rate of nucleic acid of pathogens in the juvenile group was significantly higher than that in the adult group. Conclusions:The nucleic acid detection rate and etiological distribution characteristics of respiratory pathogens are different in patients with community-acquired pneumonia in different seasons and different age groups. 13 kinds of multiple detection methods of respiratory pathogens can provide favorable laboratory data support for the diagnosis and treatment of clinical CAP patients.

Objective To investigate the effect of insulin and gliclazide therapy on endoplasmic reticulum (ER) stress and insulin sensitivity in the liver of type 2 diabetic rats.Methods A high fat diet plus a low-dose of streptozotocin was implemented to create a type 2 diabetic rats which were randomly divided into diabetes mellitus (DM) group,insulin treatment (INS) group and gliclazide treatment (GT)group; and healthy rats were as normal control group.Diabetic rats in INS and GT groups were given neutral protamine hagedorn (NPH) insulin and gliclazide respectively for 3 weeks.Protein expression levels of immunoglobulin binding protein (Bip),spliced X-box binding protein 1 (XBP-ls),phosphorylated c-Jun on serine 73 (p-c-Jun),phosphorylated insulin receptor substrate 1 on serine 307 (p-IRS-1),and glucose-6-phosphatase (G6Pase) in liver homogenate were detected by Western blotting.Results Compared with the normal rats,Bip and XBP-Is in the DM group were up-regulated (0.28 ±0.07 vs 0.90 ±0.10 for Bip;0.41 ± 0.07 vs 0.95 ±0.07 for XBP-1 s; both P ＜ 0.01 ) ; p-c-Jun (0.59 ± 0.18 vs 1.94 ± 0.03 ),p-IRS-1( 1.73 ± 0.18 vs 5.32 ± 0.22) and G6Pase (0.11 ± 0.01 vs 0.45 ± 0.01 ) were increased ( all P values ＜0.01 ).In the INS group,all of aforementioned changes were reversed (0.90 ± 0.10 vs 0.25 ± 0.04 for Bip; 0.95 ±0.07 vs 0.47 ±0.01 for XBP-1s; 1.94 ± 0.03 vs 0.50 ±0.10 for p-c-Jun; 5.32 ± 0.22 vs 1.59 ±0.32 for p-IRS-1 ; 0.45 ±0.01 vs 0.15 ±0.02 for G6Pase,all P values ＜0.01 ).In the GT group,all of aforementioned changes were also attenuated ( 0.90 ± 0.10 vs 0.53 ± 00.02 for Bip ; 0.95 ± 0.07 vs 0.78±0.02 for XBP-1s; 1.94 ±0.03 vs 1.33 ±0.11 for p-c-Jun; 5.32 ±0.22 vs 3.13 ±0.02 for p-IRS-1; 0.45 ± 0.01 vs 0.25 ± 0.01 for G6Pase,all P values ＜ 0.05).Furthermore,all of aforementioned protein levels were down-regulated more obviously in the INS group comparing to the GT group ( all P values ＜ 0.01 ).Conclusions Both insulin and gliclazide therapy could relieve ER stress and e-Jun N-terminal kinase activity and improved insulin sensitivity.The effect of insulin on Bip,XBP-1s,p-c-Jun,p-IRS-1 and G6Pase protein expressions is more obvious than that of glilcazide,which indicates besides lowering glucose,insulin might have protective effects of anti-inflammation,anti-oxidative stress or stimulation of lipid redistribution.

OBJECTIVETo explore the changes of peripheral blood lymphocyte subsets in patients with acute hydrogen chloride gas poisoning.

METHODSWhen the patients were admitted or on the secondary day, the percentages of total T-cell lymphocyte subsets (CD(3)(+)CD(19)(-)), CD(4)(+)T cells (CD(3)(+)CD(4)(+)), CD(8)(+)T cells (CD(3)(+)CD(8)(+)), B cells (CD(3)(-)CD(19)(+)) and NK cells (CD(3)(-)CD(16)(+)CD(56)(+)), and the ration of CD(4)(+)/CD(8)(+) in 37 cases with acute hydrogen chloride gas poisoning and 49 healthy controls were detected with flow cytometer.

Initial y, 102 relevant articles were retrieved, but only 48 articles were included in result analysis fol owing elimination of duplicate studies.RESULTS AND CONCLUSION:By summarizing a large number of studies on the treatment of intervertebral disc degeneration worldwide, we found that simvastatin may modulate the biological characteristics and function of nucleus pulposus mesenchymal stem cel s via promoting the expression of hypoxia-inducible factor 1αfor the endogenous stem cel-based therapy of intervertebral disc degeneration.

Larotaxel, a new taxane compound prepared by partial synthesis from 10-deacetyl baccatin Ⅲ, is active against tumors. In this research, a selective LC–MS method was developed and validated for the study of degradation kinetics of larotaxel, which was carried out in aqueous solutions with different pH (1.5, 3.0, 5.0, 6.5, 7.4, 9.0, 10 and 11.0) and temperature (0, 25, 37 and 45 °C). The linear range was 0.5–25μg/mL, the intra-and inter-day precisions were less than 7.0%, and accuracy ranged from 97.4–104.5% for each analyte. The observed rate obtained by measuring the remaining intact larotaxel was shown to follow first-order kinetics. The activation energies for degradation were 126.7 and 87.01 kJ/mol at pH 1.5 and 11, respectively. Although larotaxel was stable in pH 5, 6.5 and 7.4 buffers at 37 °C for 24 h during our study, increasing or decreasing the pH of the solutions would decrease its stabilities. Moreover, three main degradation products in alkaline condition were separated by HPLC and identified by Q–TOF–MS. The three degradation products were confirmed as 10-deacetyl larotaxel, 7, 8-cyclopropyl baccatin Ⅲ and 10-deacetyl-7, 8-cyclopropyl baccatin Ⅲ.
