Objectives To investigate the risk factors of cardiorenal syndrome type 1 (CRS1) in patients with acute myocardial infarction (AMI).Methods The medical date of hospitalized patients with AMI from January,2013 to February,2014 in Hunan Provincial People~ Hospital were reviewed.A total of 265 patients with AMI was divided into CRS1 and non-CRS1 groups.The univariate comparison and multivariate Logistic regression analysis were performed to obtain the CRS1 risk factors.Results In the 265 AMI patients,CRS1 was found in 59 patients (22.3％).Age,history of diabetes,Killip classification,left ventricular ejection fraction (LVFF),baseline serum creatinine,blood urea nitrogen,uric acid,baseline evaluated glomerular filtration rate (eGFR),serum sodium,the left anterior descending artery lesion,emergency percutaneous coronary intervention (PCI),β-blocker,and angiotensin converting enzyme inhibitor/angiotensin receptor antagonist (ACEI/ARB) were statistically different between CRS1 and non-CRS1 groups (all P ＜ 0.05).Multivariate logistic regression showed that age,history of diabetes,Killip classification,reduced LVEF,reduced eGFR,hyponatremia,the left anterior descending artery lesionn,emergency PCI non-undergo,and β-blocker non-use were independent risk factors for CRS1 after AMI.Conclusions CRS1 is a common complication in AMI patients,which is associated with many factors.Our data suggest that patients with AMI should be more comprehensively assessed and monitored,thereby preventing the occurrence of CRS1.

24. Of 6 patients positive in SDS, 4 cases scored 56 as moderate depression. Mean score was 47.62 for SDS, and 20.31 for HAM before treatment, and 32.23 for SDS, and 8.97 for HAM after 5 weeks of treatment. The differences were statistically significant (P

Extracellular recordings were made in nucleus paragigantocellularis lateralis (PGL) of the rat in response to stimulation of the dorsal periaqueductoral gray matter (dPAG), ventrolateral periaqueductuctoral gray matter (vPAG), deep peroneal nerve (DPN), median nerve (MN) and great splanchnic nerve (GSPL). Stimulation of dPAG or MN evoked mainly excitatory responses while the responses to stimulation of vPAG were inhibitory. However, stimulation of GSPL or DPN produced both inhibitory and excitatory responses. These neurons were not only responsive to one stimulation site, but were likely responsive to any other stimulation sites. Eighty-nine percent of cells tested (73/82) received convergent inputs from two or more sites. Sixty percent (21/35) of the neurons were identified as cardiovascular units based on their barosensitivity and slow conduction velocities of the descending axons projecting into the spinal cord. This result provided new evidence for the integrative function of neurons in PGL under some circumstances.

Abstract: Objective To investigate the differences in epidemiological and clinical characteristics of patients with spotted fever (SF) and severe fever with thrombocytopenia syndrome (SFTS). Methods A total of 86 patients with SF and 113 patients with SFTS who were laboratory-confirmed in the second-level and above hospitals in Lu'an City from January 2017 to January 2022 were selected. The basic data, epidemiological history, clinical data and laboratory test results of the two diseases were retrospectively analyzed for comparison. Results The proportion of male in SF group was 32.56% (28/86), and the proportion of male in SFTS group was 53.98% (61/113), the difference was statistically significant (χ2=9.067, P<0.01). The proportions of abdominal pain and diarrhea in the SF group were (3.49%, 3/83) and (21.24%, 24/113), which were significantly lower than corresponding (6.98%, 6/86) and (46.90%, 53/113) in the SFTS group (χ2=13.121, 37.322, P<0.01). The incidences of rash and eschar in SF group were 95.35% (82/86) and 20.93% (18/86), which were significantly higher than corresponding 1.77% (2/113) and 0.88% (1/113) in SFTS group (χ2=175.311, 22.721, P<0.01). The levels of leukocytes, platelets and C-reactive protein in the SF group were significantly higher than those in the SFTS group, and the levels of transaminase, lactate dehydrogenase and D-dimer were significantly lower than those in the SFTS group, and the differences were statistically significant (all P<0.05). Conclusions The rash and inflammatory reaction are more obvious in SF patients, while the liver function, myocardial function and coagulation function are significantly impaired in SFTS patients.

Objective To discuss the mechanism and characteristics of clinic presentation and neuropathology in idiopathic hypereosinophilic syndrome (IHES) encephalopathy. Methods IHES encephalopathy was diagnosed by clinical presentations,lab examinations,neurologic images,marrow and brain biopsy,then treated with corticosteroids and continuous follow-up. Results The IHES patient presented progressive limbs weakness and cognitive deficit with elevated eosinophil count. Results of lab examinations and bone marrow biopsy ruled out secondary eosinophilia and clonal eosinophilia such as eosinophilic leukemia.Brain magnetic resonance imaging (MRI) study showed multiple lesions in right frontal lobe, bilateral parietal and occipital lobe, presenting hypointensity in T1 weighted images,hyperintensity in T2 and fluid-attenuated inversion recovery weighed images. Brain biopsy showed proliferation of vascular membrane,small vessels stenosis,ischemia-induced morphological change and necrosis of neurons in the lesions.The patient was continuously treated with corticosteroids,and the situation was stabilized with follow-up.Conclusions IHES encephalopathy should be paid more attention in clinical practice of neurologists for its rarity. Brain vascular damages caused by elevated eosinophil may be an important pathophysiological mechanism of IHES encephalopathy,and corticosteroids or hydroxycarbamide should be used for the treatment.

Objective:To construct the plant expression vector of Der f1 allergen of Dermatophagoides pteronyssinu and expression in tobacco lamina.Methods:The Der f1 gene was amplified from the glycerin bacterium which contained pET28a(+)-Der f1 plasmid,cloned into the pMD 19-T plasmid,and then sequenced.The Der f1 gene was digested by ClaⅠand SalⅠ,and cloned into potato virus X (PVX) to construct plant expression vector PVX-Der f1,and then was transformed agrobacterium tumefaciens.The positive one was selected to infect tobacco lamina for expressing target protein.The protein was identified and analysed by SDS-PAGEand Western blot.Results:Digestion and sequence analysis confirmed that the plant expression vector was correct,and the SDS-PAGE and Western blot results showed that the molecular weight of the protein was about 34M_r and it could specific binding with positive serum.Conclusion:The plant expression vector of Der f1 is successfully constructed and the recombinant protein is also produced.

Objective To identify the risk factors of delirium in ICU by Meta-analysis. Methods Quality of the studies was assessed in terms of study design, definitions of main variables, statistics, and bias control. Analysis of sensitivity and heterogeneity were performed and cumulative effects were calculated using either fixed or random effects models by RevMan 4.2.Results Ten studies met all inclusive and exclusive criteria. Simple sizes range from 100 to 3308. Twenty-one risk factors of delirium in ICU were involved, but only alcohol abuse, respiratory disease, infection, APACHE Ⅱ,elevated level of serum urea nitrogen, hyponatremia, hyperbilirubinemia and using sedatives were identified as having a cumulative effect on delirium in ICU. Conclusions Infection, abnormality or disturbance of metabolism and intoxication or acute withdrawal from drug or alcohol are independent predictors of delirium in ICU, while advanced age and hypoxemia, which are commonly considered as independent risk factors of delirium in ICU, are still inconclusive.

In order to investigate the characteristics of transdermal delivery of ferulic acid under the treated of microneedle arrays and the influence on permeability of rat skin capillaries, improved Franz-cells were used in the transdermal delivery experiment with the rat skin of abdominal wall and the length of microneedle arrays, different insertion forces, retention time were studied in the influence of characteristics of transdermal delivery of FA. The amount of FA was determined by HPLC system. Intravenous injection Evans blue and FA was added after microneedle arrays treated. Established inflammation model was built by daubing dimethylbenzene. The amount of Evans blue in the rat skin was read at 590 nm wavelength with a Multiskan Go microplate reader. Compared with passive diffusion group the skin pretreated with microneedle arrays had a remarkable enhancement of FA transport (P <0.01). The accumulation of FA increased with the enhancement of insertion force as to as the increase of retention time. Microneedle arrays with different length had a remarkable enhancement of FA transport, but was not related to the increase of the length. The research of FA on the reduce of permeability of rat skin capillaries indicated that the skin pretreated with microneedle arrays could reduce the content of Evans blue in the skins of rat significantly compared with the untreated group. The permeation rate of ferulic acid transdermal delivery had remarkable increase under the treated of microneedle arrays and the length of microneedle arrays ,the retention time so as to the insertion force were important to the transdermal delivery of ferulic acid.

A complex disease is rarely a consequence of abnormality in a single gene. It is known that many drugs exhibit a therapeutic effect by acting on multiple targets, produce synergies to intervene the occurrence and development of diseases. Unlike the traditional methods which act on single molecule or pathway, this disease-drug target network constructed with high throughput data vividly showed the complex relationship between drugs, their targets and diseases. However, the networks are usually extremely complex. In order to reduce the complexity, it is necessary to deconstruct the network and identify module structures. In this study, framework of module analysis was summarized from four aspects: module concept, structure and identification methods, importance of disease-drug module identification, and its application. Module-based analysis provides a new perspective for deciphering the drug intervention mechanisms for complex diseases, and provides new ideas and pathways to reveal the mechanisms of multi-target and multi-component drugs.
