Objective To study the relation between the TCM constitution and the lung function of asthmatic bronchitis children to lay a foundation to apply the TCM constitution theory in preventing and treating children asthmatic diseases.Methods Following the Zhu's method,120 asthmatic bronchitis children were divided into normal constitution,phlegm-damp constitution,qi deficiency constitution,internal heat constitution,and both qi and yin deficiency constitution.Based on the Su's method,the cases were classified into balance constitution,lung-spleen Ⅰ constitution,lung-spleen Ⅱ constitution,spleen-kidney Ⅰ constitution,and spleen-kidney Ⅱ constitution.Their lung function was tested and the TPTEF /Te and VPTEF/Ve of each constitution were analyzed.Results Of the 120 cases,37 ones (30.8%) were qi deficiency constitution;33 ones (27.5%) were phlegm-damp constitution;and 60 ones (50.0%) were lung-spleen Ⅱ constitution.Compared with those with normal constitution,the cases with the phlegm-damp constitution,qi deficiency constitution,internal heat constitution,and both qi and yin deficiency constitution had significantly lowered TPTEF/Te and VPTEF/Ve (P

Objective:To study the effect of bronchoscope lavage on the inflammatory mediators and pulmonary function of patients with refractory pneumonia.Methods:100 cases of patients with refractory pneumonia who were treated in our hospital from January 2010 to December 2015 were selected and randomly divided into two groups,the control group was treated with routine clinical treatment,and the observation group was treated with bronchoscope lavage.The curative effect and the changes of inflammatory mediators and pulmonary function of the two groups after treatment were compared.Results:After treatment,the effective rate of observation group was 90.00％(45/50),which was significantly higher than that of the control group (76.00％,38/50) (P＜0.05);the levels of endotoxin,IL-6,TNF-2 and LPO in the bronchoalveolar lavage fluid of both groups were significantly decreased (P＜0.05),which were decreased more significantly in the observation group (P＜0.05),the pulmonary function of both groups were significantly improved(P＜0.05),which improved more significantly in the observation group(P＜0.05).Conclusions:Bronchoscope lavage had good therapeutic effect on the patients with refractory pneumonia,it could effectively reduce the level of inflammatory mediators and improve the lung function.

BACKGROUND:There are more literature reports about the floating shoulder injury in recent years, but there stil have obvious controversies about the treatment of the floating shoulder injury. Whether choose the conservative treatment or operative treatment is an important issue in face of every clinician. OBJECTIVE:To review the clinical features and present treatment situation of the floating shoulder injury. METHODS: A computer-based online search was performed in the PubMed and the China National Knowledge Infrastructure database for the clinical research papers on the treatment methods of the floating shoulder injury from January 1975 to August 2015. The key words were floating shoulder injury, diagnose, treatment method. The articles published earlier and repetitive researches were excluded. Finaly, 33 articles were included for further analysis. RESULTS AND CONCLUSION:(1) Floating shoulder injury is a kind of severe shoulder injury which is caused by high energy and violence. It is often complicated with severe systemic injury, which should be paid more attention in clinic. (2) The treatment of floating shoulder injury has been controversial, and there is no standard treatment guideline. Conservative treatment and operative treatment can get good outcomes. There are less reports about conservative treatment of the floating shoulder injury in recent years. The outcome of operative treatment may better than conservative treatment. (3) Conservative or simple clavicle fixation can be used for fractures without displacement or with smal displacement. Obviously displaced fractures can be treated with simple clavicle fixation or double fixation of clavicle and scapula, which may have good repair effects.

Objective To compare curve-tip angiography guide wire (loach guide wire) and ultrasmooth hydrophilic guide wire (zebra guide wire) in selective common bile duct (CBD) cannulation of endoscopic retrograde cholangiopancreatography (ERCP). Methods A total of 196 patients were randomly assigned to loach guide wire group to receive cannulation guided by loach guide wire first ( n = 98 ) and zebra guide wire group to use zebra guide wire first ( n =98). If cannulation was not successful after 10 minutes, a further attempt was made for an additional 10 minutes using the alternative guide wire. If still not successful after 10 minutes, other cannulation accessories would be used. The primary and overall selective cannulation time, success rate, and post-procedure abdominal pain and serum amylase were assessed. Results The primary success rate of selective CBD cannulation was higher in the loach guide wire group (93.9%) than that in zebra guide wire group (86. 7%, P ＜0. 05), while there was no significant difference in cannulation time between 2 groups (P ＞ 0. 05 ). The cannulation success rate after crossover was higher in loach guide wire group (76. 9% ) than that in zebra guide wire group (0. 0%, P ＜0. 05). There was no significant difference in post-procedure serum amylase or occurrence rate of post ERCP pancreatitis between 2 groups (P ＞ 0. 05 ).Conclusion Loach guide wire is superior to zebra guide wire in ERCP selective CBD cannulation, which can replace zebra guide wire in difficult cannulation.

Objective To investigate the diagnostic value of intraductal ultrasonography for the quality of biliary stricture.Methods Data of the patients who had received operation because of biliary stricture after IDUS examination from 2006 to 2010 were collected.IDUS results were compared with those of operation.Results There were 43 cases of malignant strictures and 6 benign strictures in total.The sensitivity,specificity,positive predictive value,negative predictive value and diagnostic accuracy of intraductal uhrasonography for the quality of biliary stricture were 97.7％ ( 42/43 ),83.3％ ( 5/6 ),97.7％ ( 42/43 ),83.3％ (5/6) and 95.9％ (47/49),respectively,which were significantly higher than conventional imaging like ultrasound B,CT and MRCP.Twenty one cases in 32 were diagnosed as malignant biliary stricture with cytological brushing,with the diagnostic accuracy of 65.6％.All cases had been diagnosed by IDUS.Conclusion Intraductal ultrasonography is of high diagnostic value for biliary stricture.However,cytological brushing based on IDUS is of limited diagnostic value for malignant biliary stricture.

Objective To research the changes in hippocampal voltage-gated sodium channel of Lithium chloride-Pilocarpine epileptic rat models,including Ⅰ sodium channel α subunit protein (Nav1.1),mRNA of Ⅰ sodium channel alpha subunit protein gene and function of sodium channel.Methods Epileptic rat models of Lithium chloride-Pilocarpine were established.Nav1.1 expression in the hippocampus of experimental rats was detected by immunohistochemical staining method,and the changes in voltage-gated sodium channel function (the current-voltage curves,activation and inactivation curves and the recovery curve) of hippocampus nerve cells were detected by whole cell patch-clamp technique.Results (1) The Lithium chloride-Pilocarpine rat models were successfully reproduced.Three stages of behavior (acute,latent and chronic) of rat models were observed.The blank control group was free of seizure.(2) Immunohistochemistry results:neurons in CA1 and DG regions of hippocampal of epileptic rats were normal,and there was no obvious change in the expression of Nav1.1.In CA3 area,the degeneration and necrosis of neurons were obvious.Staining of Nav1.1 became superficial and even disappeared in these areas,but the normal tissues were enhanced around degenerative and necrotic neurons.Compared with the blank control group,the expression of Nav1.1 in the model group was higher(0.235 ±0.008 vs.O.210 ±0.002),and there was statistically significant difference (t'=-7.426,P ＜ 0.05).(3) The whole-cell patch-clamp technique showed that the sodium current density of the model group increased significantly compared with that of the blank group [(-319.70 ± 28.24) pA/pF vs.(-229.06 ± 26.01) pA/pF,t =8.178,P ＜ 0.05],the threshold value of activation curve decreased (4.15 ± 0.80 vs.4.50 ±0.85,t =11.020,P ＜ 0.05),the threshold value of inactivation curve increased (7.47 ± 0.53 vs.6.24 ±0.31,t =6.940,P ＜ 0.05),and the recovery time after inactivation shortened [(1.36 ± 0.15) ms vs.(1.86 ± 0.21)ms,t =6.712,P ＜ 0.05],and there were all statistically significant differences.Conclusion Repeated seizures can lead to increase Nav1.1 compensatory expression of,and significantly increase sodium channel current density,while the threshold value of activation curve decreases,the threshold value of inactivation curve rises,and the recovery time after inactivation is shortened,which eventually leads to increased neuron excitability and is more likely to cause seizures.

Objective To explore the effect of ultrasound therapy on dysphagia caused by radiotherapy for nasopharyngeal carcinoma. Methods From February to December, 2017, 60 patients with radiation-induced dysphagia for nasopharyngeal carcinoma were randomly divided into control group (n = 30) and treatment group (n = 30). All the patients accepted routine rehabilitation and balloon dilatation. The treatment group received ultrasound therapy, and the control group received placebo ultrasound. They were evaluated with Kubota Drinking Water Test (KDWT) and Videofluoroscopic Swallowing Study (VFSS), and the interincisor distance were measured to determine the clinical effect, before and six weeks after treatment. Results The score of KDWT (Z = -2.253, P < 0.05) and the pass time in VFSS (t > 2.4265, P < 0.05) improved more in the treatment group than in the control group after treatment, as well as the incidence of effect (Z = -4.113, P < 0.001). Conclusion Ultrasound therapy can further improve the function of swallowing based on the balloon dilatation.

Objective To identify and validate co-expressed genes associated with myocardial ischemia/reperfusion injury(MI/RI)and necrotic apoptosis by bioinformatics analysis.Methods Gene expression profile data for MI/RI were obtained by GSE67308 and GSE19875 datasets from the Gene Expression Omnibus(GEO)database.Differential expression analysis was conducted on the GSE67308 dataset to identify differentially expressed genes(DEGs),followed by gene set enrichment analysis and biological pathway analysis.More-over,immune cell infiltration analysis was performed on the GSE67308 dataset.Necrotic apoptosis-related genes were retrieved from the Molecular Signatures Database and the Kyoto Encyclopedia of Genes and Genomes(KEGG).A protein-protein interaction(PPI)network was constructed by overlapping DEGs with these necrotic apoptosis-related genes to identify key genes.Furthermore,the expression pat-terns of these key genes across various cardiac cell types were analyzed using a single-cell sequencing analysis platform,and validation of key gene expression was performed using the GSE19875 dataset.Results A total of 1054 DEGs were identified,comprising 363 upregu-lated and 691 downregulated genes.Gene enrichment analysis revealed that DEGs were primarily associated with processes related to apoptosis,immune responses,and intracellular signaling regulation.Moreover,biological pathway analysis demonstrated that DEGs were predominantly involved in the regulation of signaling pathways such as tumor necrosis factor(TNF)and NF-κB.Immune infiltration anal-ysis indicated a high degree of immune infiltration,particularly with natural killer cells and monocytes,in MI/RI myocardial tissue.PPI network analysis identified Il1b,TNF,Birc3,and Ripk1as crucial genes in the context of necrotic apoptosis.Single-cell sequencing anal-ysis showed the elevated expression of key genes within white blood cells.In comparison to the control group,the MI/RI model group in the GSE19875 dataset exhibited significantly increased expression of Il1b,TNF,Birc3,and Ripk1(P<0.01).Conclusion MI/RI is strongly correlated with the TNF signaling pathway and the NF-κB signaling pathway,both of which play pivotal roles in regulating necrotic apop-tosis.Il1b,TNF,Birc3,and Ripk1emerge as key genes that concurrently regulate both MI/RI and necrotic apoptosis.It is plausible that IL-1b,TNF,Birc3,and Ripk1 may serve as critical regulatory factors in the context of necrotic apoptosis during MI/RI.

Objective:To assess the association between the different prehospital transfer pathways to the hospital and reperfusion delay in patients with ST segment elevation myocardial infarction (STEMI).Methods:We retrospective collected 320 STEMI patients aged 18 years or older who underwent primary percutaneous coronary intervention (PPCI) from June 1, 2016 to July 31, 2018. They were divided into three groups according to different prehospital transfer pathways: patients directly transferred from the field by ambulance to PCI-capable center hospital (field transfer group, n=29); patients transferred by ambulance from PCI-incapable hospitals to PCI-capable center hospital (inerhospital transfer group, n=111); patients transferred by friends or relatives to PCI-capable center hospital (self-transfer group, n=180). The basic characteristic attributes, reperfusion time and fatal complications such as acute left heart failure cases (ALHF) cases, ventricular fibrillation (VF) cases, and in hospital death were collected and compared. In addition, logistic regression analysis was used to analyze uni- and multivariate of door-to-balloon (D2B) time less than 90 min. Results:The S2FMC interval were 118 min (50, 377) min , FMC-to-balloon interval were 87 min (66, 120.5) min and the onset-to-balloon time were 221 min (135, 482.5) min. The above three interval in the interhospital transfer group were longer than those in the field transfer and self-transfer groups ( P<0.05). S2FMC accounted for 51.14% of onset-to-balloon time in the field transfer group, 63.29% in the interhospital transfer group and 55.26% in the self transfer group. The door-to-catheter room interval were 33 min (9, 53.5) min. The interval in the interhospital transfer group were shorter than those in the field transfer and self-transfer groups ( P<0.05). The interval in the self-transfer group were longer than those in the interhospital transfer and field transfer groups ( P<0.05). Multiple regression analysis showed that the interhospital transfer group ( OR=15.251, 95% CI: 5.328-43.657, P<0.01), field transfer group ( OR=8.219, 95% CI: 1.861-36.307, P=0.005), FMC2ECG time ( OR=0.975, 95% CI: 0.962-0.989, P<0.01), and smoking ( OR=2.099, 95% CI: 1.015-4.341, P=0.045) were independent predictor of goal time less than 90 min ( P<0.05 for all variables). Adverse events in STEMI patients mainly occurred within 6 h of the initial symptoms. The incidence of VF was 3.75% (95% CI: 3.73%-3.77%), ALHF was 10.94% (95% CI: 7.52%-14.36%) and in-hospital mortality was 2.5% (95% CI: 0.79%-4.21%). There was no significant difference in the incidence of adverse events among the three groups ( P>0.05). Conclusions:The symptoms of STEMI patients are at risk in the early stage. Ambulances can shorten the reperfusion time, but the ambulance system is less used by patients. It is necessary to further optimize the treatment process of non-PCI hospitals and strengthen the popularity of emergency knowledge related to chest pain among residents, so as to shorten the reperfusion time.
