OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.

METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.

RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.

CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

The present study was to investigate the effect of glucagon like peptide-1 (GLP-1) on high glucose-induced oxidative stress of cardiomyocytes and the possible role of the PI3K-Akt signal path in this process in the neonatal SD rats. With enzymatic digestion and immunofluorescence identification, cardiomyocytes after 72-96 h of primary culture were used in experiment. The cells were divided into 5 groups: normal control group, high glucose group, high glucose + GLP-1 group, high glucose + GLP-1 + LY294002 group and high osmolarity control group. The content of MDA was detected by TBA colouration method. The content of SOD was detected by xanthine oxidase method. The change of NADPH P47phox subunit mRNA quantity was detected by PCR gel electrophoresis. The level of ROS was detected by flow cytometry, and was also observed by fluorescence microscope. The DNA ladder was examined by agarose gel electrophoresis, and the cell apoptosis was determined by Annexin-V-FITC/PI flow cytometry, and the phosphorylation of Akt was determined by Western blotting. Compared with those in the normal control group, in the high glucose group, the cells grew poorly, and the beating rate was significantly lower (P < 0.05); The apoptotic rate was significantly increased (P < 0.05); The MDA content was increased (P < 0.05); It showed the typical DNA ladder, which is the characteristic of apoptosis; The SOD activity was decreased (P < 0.05); The level of intracellular ROS increased (P < 0.05); And the expression of NADPH P47phox subunit mRNA was increased; However the phosphorylation level of Akt was decreased. Pretreatment with GLP-1 improved the above-mentioned parameters and decreased the expression of NADPH P47phox subunit mRNA (P < 0.05). However, compared with the high glucose + GLP-1 group, LY294002, an inhibitor of PI3K-Akt signal path, attenuated the protective effect of GLP-1 in the high glucose + GLP-1 + LY294002 group. It is suggested that GLP-1 plays a protective role in the high glucose-induced injury and apoptosis of cardiomyocytes, and the PI3K-Akt signal path is involved in this process.

Objective To survey avian influenza A viruses (AlVs) in the environment and explore the reasons for the surge in human H7N9 cases.Methods A total of 1,045 samples were collected from routine surveillance on poultry-related environments and 307 samples from human H7N9 cases-exposed environments in Henan from 2016 to 2017.The nucleic acids of influenza A (Flu A),H5,H7,and H9 subtypes were detected by real-time polymerase chain reaction.Results A total of 27 H7N9 cases were confirmed in Henan from 2016 to 2017,24 had a history of live poultry exposure,and 15 had H7N9 virus detected in the related live poultry markets (LPMs).About 96％ (264/275) Flu A positive-environmental samples were from LPMs.H9 was the main AIV subtype (10.05％) from routine surveillance sites with only 1 H7-positive sample,whereas 21.17％ samples were H7-positive in H7N9 cases-exposed environments.Samples from H7N9 cases-exposed LPMs (47.56％)had much higher AIVs positive rates than those from routine surveillance sites (12.34％).The H7+H9 combination of mixed infection was 78.18％ (43/55) of H7-positive samples and 41.34％ (43/104) of H9-positive samples.Conclusion The contamination status of AIVs in poultry-related environments is closely associated with the incidence of human infection caused by AlVs.Therefore,systematic surveillance of AlVs in LPMs in China is essential for the detection of novel reassortant viruses and their potential for interspecies transmission.

Objective To explore the psychological status and nursing strategy for craniocerebral trauma patients with hearing loss.Methods To induce and analyze the psychological status of 112 raniocerebral trauma patients with hearing loss from May 2008 to March 2013 so as to explore the well-targeted nursing measures.Results There existed five different kinds of psychological problems among 112 craniocerebral trauma patients with hearing loss.42(37.50％) patients worried that the hearing failed to recover,which would affect the quality of their lives,thus sunk into low spirits or even a state of depression; 31 (27.68％) patients worried that they were not treated in time by the doctors,which would adversely affecting the best time of treatment;26(23.21％) patients feared that they wouldn't get the compensation from the responsible party; 11 (9.82％)patients were pseudo-deaf or exaggerated deaf; 2 (1.79％) patients sought for excessive medical treatment.Conclusions The nursing staff should observe the patients' hearing conditions in time and guide patients to correctly deal with hearing loss,should treat patients equitably,in order to make patients get accurate diagnosis,appropriate and effective treatments,and should timely check and backup the test information related hearing so as to help them get rid of bad attitudes as soon as possible,correctly face what might happen,and improve the quality of life.

Objective To study the relationship between the changes of sagittal spinopelvic parameters and facet joint-derived low back pain in patients with hip osteoarthritis after hip arthroplasty.Methods The clinical data of 30 patients with facet joint-derived low back pain induced by hip osteoarthritis who underwent unilateral hip arthroplasty(observation group)from June 2019 to November 2020 in our hospital were retrospectively analyzed,and 50 healthy subjects who underwent lumbar X-ray examination in the physical examination center of our hospital at the same time were randomly selected as the control group.The sagittal spinopelvic parameters were measured based on the X-ray,including pelvic incidence(PI),pelvic tilt(PT),sacral slope(SS),lumbar lordosis(LL),sacrum pubic incidence(SPI)and sacrum pubic posterior angle(SPPA).The correlation between the changes of sagittal spinopelvic parameters and facet joint-derived low back pain was analyzed by multiple linear regression,and its diagnostic efficacy to facet joint-derived low back pain was analyzed by receiver operating characteristic(ROC)curve.Results The PI,LL,SPI or SPA before and 1 year after surgery of the observation group had no significant difference combined with those of the control group(P>0.05).The PT before surgery of the observation group was smaller than that of the control group(P<0.05),and the SS before surgery was larger than that of the control group(P<0.05).Multiple linear regression analysis showed that PT and SS before surgery were correlated with facet joint-derived low back pain(P<0.05).The sensitivity of PT and SS before surgery in diagnosing facet joint-derived low back pain were 50.00%and 73.30%,with the specificity of 88.00%and 78.00%,respectively.ROC curve analysis showed that the area under the curve of PT and SS before surgery in diagnosing facet joint-derived low back pain were 0.708(95%CI:0.595 to 0.822)and 0.775(95%CI:0.673 to 0.877),respectively.Conclusion Patients with hip osteoarthritis pain have significantly larger SS and significantly smaller PT.Hip arthroplasty can alleviate the symptoms of low back pain without affecting the sagittal spinopelvic balance;the PT and SS before surgery are correlated with the facet joint-derived low back pain,and they are of high value in the diagnosing facet joint-derived low back pain.

Objective:To evaluate the efficacy of visualized precise lung expansion for determining the intersegmental plane in thoracoscopic segmentectomy.Methods:Sixty-four American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, regardless of gender, aged 33-77 yr, with body mass index of 16-34 kg/m 2, undergoing elective thoracoscopic segmentectomy under general anesthesia, were included. They were preoperatively reconstructed with 3D CT bronchovascularization to reconstruct the pulmonary vasculature, bronchus, and the virtual intersegmental planes of the lungs. The patients were divided into 2 groups ( n=32 each) using a random number table method: visualized precise lung expansion group (group V) and modified expansion and atrophy group (group E). Group V used visualized precision lung expansion to determine the intersegmental planes, and group E used the modified expansion and atrophy method to determine the intersegmental planes. The intraoperative intersegmental plane determination time, target segmental bronchus identification and treatment time, anesthesia time, operation time, postoperative air leakage, pulmonary atelectasis, fever, occurrence of lung infection, postoperative 24 h drainage volume, drain removal time and hospitalization time were recorded in the two groups. Results:Compared with group E, the intersegmental plane determination time, target segment bronchial identification and treatment time, anesthesia time and operation time were significantly shortened in group V( P<0.05).There were no significant differences between groups in the 24 h postoperative drainage volume, drain removal time, hospitalization time or incidence of postoperative pulmonary complications ( P>0.05). Conclusions:Compared with the modified expansion and atrophy method, visualized precise lung expansion can effectively shorten the intersegmental plane determination time in thoracoscopic segmentectomy.
