ABSTRACT
Sensory processing is strongly modulated by different brain and behavioral states, and this is based on the top-down modulation. In the olfactory system, local neural circuits in the olfactory bulb (OB) are innervated by centrifugal afferents in order to regulate the processing of olfactory information in the OB under different behavioral states. The purpose of the present study was to explore the organization of neural networks in olfactory-related cortices and modulatory nuclei that give rise to direct and indirect innervations to the glomerular layer (GL) of the OB at the whole-brain scale. Injection of different recombinant attenuated neurotropic viruses into the GL showed that it received direct inputs from each layer in the OB, centrifugal inputs from the ipsilateralanterior olfactory nucleus (AON), anterior piriform cortex (Pir), and horizontal limb of diagonal band of Broca (HDB), and various indirect inputs from bilateral cortical neurons in the AON, Pir, amygdala, entorhinal cortex, hippocampus, HDB, dorsal raphe, median raphe and locus coeruleus. These results provide a circuitry basis that will help further understand the mechanism by which olfactory information-processing in the OB is regulated.
ABSTRACT
Objective To investigate the clinical features of drug -induced liver injury (DILI) and related risk factors.Methods A retrospective analysis was performed for the clinical data of 208 patients who were diagnosed with DILI in The Affiliated Hospital of Southwest Medical University from January 2013 to November 2017, including the type of drugs, clinical data, and laboratory examination results, and among these patients, 80 with DILI caused by antitubercular agents, antitumor drugs, and immune agents were enrolled as observation group.A total of 80 patients who used these three types of drugs and did not develop DILI were enrolled as control group .Related risk factors were analyzed.An analysis of variance was used for comparison of normally distributed continuous data between multiple groups , and the Kruskal -Wallis H test was used for comparison of non -normally distributed continuous data between multiple groups .The chi -square test was used for unordered variables of categorical data , the Mann -Whitney U test was used for ranked data, and a logistic regression analysis was used to identify risk factors.Results Of all patients with DILI, 30.8% had DILI caused by traditional Chinese medicine .There were significant differences in sex, alanine aminotransferase, aspartate aminotransferase (AST), total bilirubin (TBil), gamma -glutamyl transpeptidase (GGT), and total bile acid (TBA) between patients with different types of DILI (χ2 =6.081, H =54.349, 45.993,78.902, 49.940, and 21.934, all P <0.05).There were significant differences in AST, TBil, GGT, and TBA between the patients with different prognoses (H =1.728, 6.322, 6.440, and 2.353, all P <0.05).Smoking (odds ratio [OR] =2.856, P =0.026), diabetes (OR =2.726, P =0.042), hyperlipidemia (OR =3.390, P =0.003), and body mass index (BMI) ≥28 kg/m2 (OR =3.142, P = 0.009) were risk factors for DILI.Conclusion Most DILI cases are caused by traditional Chinese medicine , and hepatocellular type is the most common type of liver injury.Smoking, diabetes, hyperlipidemia, and BMI ≥28 kg/m2 are risk factors for DILI.
ABSTRACT
Astract: Objective To explore the efifcacy and safety of endoscopic tissue adhesive injection in treatment of gastric variceal bleeding from liver cirrhosis.Methods Object of study are 92 cirrhotic patients (72 male/20 female) in hospital, who had been diagnosed with gastric varices bleeding from June 2014 to May 2016. Child-Pugh score at presentation for cirrhotic patients was A-28; B-36; C-28. According to endoscopic classiifcation of gastric varices, GEV1 were detected in 80 patients, GEV2 in 12. All patients were treated with endoscopic hypertonic glucose tissue adhesive ‘sandwich’ injection.Result Successful injection rate was 100.0% in 92 patients, among which 40 patients had accepted emergency endoscopic treatment and the immediate hemostasis rate was 100.0%. 65 patients were Having gastroscope review after the injection six months, 22 patients were significantly effective, accounting for 33.8%; 38 patients were effective, accounting for 58.4%; 5 patients were invalid, accounting for 7.7%. All the patients were followed up in 1 to 24 months. The late-rebleeding rate was 2.2%. None of them were having early-rebleeding or dead; Complications the incidence of rebleeding rate which caused by removing the needles which trapped in the varices was 2.2%. The incidence of chest pain rate was 4.3%, the bloating rate was 6.5% and the ulceration rate was 15.2%. There was no complications like fever, infection, stomachache, embolism and so on.Conclusion With low rebleeding rate and light side-effect, endoscopic tissue adhesive injection in the treatment of gastric variceal bleeding caused by cirrhosis portal hypertension has really good effect.
ABSTRACT
OBJECTIVE:To evaluate the effectiveness,safety and economics of antibiotics for inpatients with acute exacerba-tion of chronic obstructive pulmonary diseases (AECOPD),in order to promote rational use of antibiotics. METHODS:In retro-spective study,AECOPD inpatients were selected as research objects during 2013-2015 to evaluate the use of antibiotics. RE-SULTS:Three thousand one hundred and eighty-six AECOPD patients were enrolled in the study,and utilization ratio of antibiot-ics was above 90%. DDDs of Cefordizime sodium for injection ranked the first place in 3 years and was decreased in 2015,while those of β-lactam and carbapenems were increased. DDC of Meropenem for injection and Imipenem/cilastatin sodium for injection were the highest. Drug utilization index(DUI)of Cefodizime for injection was far more than 1.0,while DUI of Piperacillin sodi-um and sulbactam sodium for injection was much less than 1.0. Sort ratio(B/A)of Cefodizime sodium for injection ranged 1-2 in 3 years. B/A of Piperacillin sodium and sulbactam sodium for injection,Imipenem and cilastatin sodium for injection,Meropenem for injection were lower than 1.0. CONCLUSIONS:The indication of anti-infective treatment in AECOPD patients have been mas-tered strictly in our hospital;the utilization ratio of antibiotics is decreased year by year;the types of antibiotics are rational rela-tively,and the number of antibiotics which is rationally used is increased year by year. But the rationality of Cefodizime sodium for injection and Piperacillin sodium/sulbactam sodium for injection need to be improved.
ABSTRACT
OBJECTIVE:To investigate the relationship of drug utilization index(DUI)of antibiotics with therapeutic efficacy of patients with acute exacorbation of chronic obstructive pulmonary disease(AECOPD). METHODS:By the method of drug utili-zation evaluation,inpatients with AECOPD in our hospital during 2013-2015 were selected as the research object. Diagnosis and treatment information prescribing information of patients were collected,and inpatients only receiving one kinds of antibiotics dur-ing hospitalization stay were selected to evaluate the relationship of therapeutic efficacy with rehospitalization indexes. RESULTS:A total of 2155 AECOPD patients were enrolled in the study. Among antibiotics with DDDs>500,antibiotics with DUI close to 1.0 was cefotiam hydrochloride for injection,and that with DUI far higher than 1.0 was Cefodizime sodium for injection,while that with DUI much less than 1.0 was Piperacillin sodium and sulbactam sodium for injection. There was statistical significance in therapeutic efficacy between Cefotian hydrochloride for injection and Piperacillin sodium and sulbaactam for injection (P0.05). There was no statistical significance in therapentic efficacy or rehospital-ization between cefotiam hydrochloride for injection and cefodizimes sodium for injection(P>0.05). CONCLUSIONS:DUI is as-sociated with therapeutic efficacy,but the rationality of antibiotics can not be simple judged according to the distance between DUI and 1.0. A variety of confounding and bias factors should be integrated to avoid misreading and misjudgment.
