RESUMO

Objective To analyze the characteristics of sniffing therapy in China and abroad,to provide data support and reference for the establishment of clinical application guidelines for sniffing therapy,and to promote the multidimensional development of sniffing therapy.Methods Using the literature on sniffing therapy to retrieve clinical research,which were retrieved from the databases of CNKI,Wanfang,VIP,PubMed,WOS core database,SD as the data sources,we summarized the type of treatment,treatment route,primary disease and Indications,drug composition,treatment mode,treatment dose,duration,frequency and periodicity.Results A total of 158 papers were screened,of which the treatment types were mainly plant essential oils;direct sniffing was the main treatment route in sniffing therapy;auxiliary tools were mostly cotton(balls)or diffusers,etc.;main treatment for neurological disorders,brain disorders and affective disorders were the most common;lavender was the most frequently used drug;drug forms were widely used in single prescriptions,often in combination with western drugs;the duration of drug use was commonly 30 min.The ambiguous dose of clinical trials is mostly 2 drops;its frequency of administration is mostly twice a day;the duration of treatment is more common in 15-30 day.Conclusion Sniffing therapy has been widely studied,with the particular advantages of being non-invasive,free of side effects,simple to operate and cost effective.But the strong volatility of aromatic substances and the subjective nature of odour recognition,coupled with the lack of scientific and unified objective treatment standards,make a slight difference in efficacy.Therefore,based on the clarification of the characteristics of sniffing therapy,standardization and innovation are of great significance to its efficient development.

RESUMO

To develop a novel glucose-lowering biomedicine with potential benefits in the treatment of type 2 diabetes, we used the 10rolGLP-1 gene previously constructed in our laboratory and the CRISPR/Cas9 genome editing technique to create an engineered Saccharomyces cerevisiae strain. The gRNA expression vector pYES2-gRNA, the donor vector pNK1-L-PGK-10rolGLP-1-R and the Cas9 expression vector pGADT7-Cas9 were constructed and co-transformed into S. cerevisiae INVSc1 strain, with the PGK-10rolGLP-1 expressing unit specifically knocked in through homologous recombination. Finally, an S. cerevisiae strain highly expressing the 10rolGLP-1 with glucose-lowering activity was obtained. SDS-PAGE and Western blotting results confirmed that two recombinant strains of S. cerevisiae stably expressed the 10rolGLP-1 and exhibited the desired glucose-lowering property when orally administered to mice. Hypoglycemic experiment results showed that the recombinant hypoglycemic S. cerevisiae strain offered a highly hypoglycemic effect on the diabetic mouse model, and the blood glucose decline was adagio, which can avoid the dangerous consequences caused by rapid decline in blood glucose. Moreover, the body weight and other symptoms such as polyuria also improved significantly, indicating that the orally hypoglycemic S. cerevisiae strain that we constructed may develop into an effective, safe, economic, practical and ideal functional food for type 2 diabetes mellitus treatment.

RESUMO

Objective:To investigate the protective effect of IL-22 on rat liver ischemia reperfusion injury (IRI) and the potential mechanisms.Methods:Eighteen male specific pathogen free SD rats (7-8 weeks, about 250g) were randomly divided into three groups: Sham group (Sham), hepatic ischemia reperfusion (IRI) and IL-22 preconditioning group (IL-22+ IRI), respectively. The liver IRI model of 70% rats was established. The IL-22+ IRI group was intraperitoneally injected with rcIL-22 (50 mg/kg) 1 hour before surgery, and the Sham group and IRI group were injected with the same dose of normal saline 1 hour before surgery. After 1 h ischemia and 6 h reperfusion, blood was collected from the abdominal aorta, then liver tissue, serum aspartate transaminase (AST) and alanine aminotransfease (ALT) levels were measured. The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in liver tissue were detected. The expression of signal transducer and activator of transcription 3 (STAT3), p-STAT3, nuclear factor erythorid-2 related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) were detected by Western blot. Results:Compared with Sham group, serum AST [(1 923.50±92.63) U/L, (1 004.25±65.05) U/L)] and ALT [(1 172.51±180.31) U/L, (583.50±164.75) U/L] levels were increased in IRI group and IL-22+ IRI group (AST: F=293.62; ALT: F=30.33, P<0.05). The levels of MDA in IRI group and IL-22+ IRI group [(1.72±0.12) μmol/mg, (0.98±0.05) μmol/mg] in liver tissue were higher than those in Sham group (0.58±0.14) μmol/mg protein ( F=186.73, P<0.05), and the expression of p-STAT3, Nrf2 and HO-1 was increased. SOD level in IRI group (28.51±3.85) U/mg was lower than that in Sham group (70.25±5.64) U/mg protein ( F=203.41, P<0.05). Compared with IRI group, serum AST and ALT levels in IL-22+ IRI group were decreased, SOD activity in liver tissue was increased, MDA level was decreased, and p-STAT3, Nrf2 and HO-1 expression was increased (all P<0.05). Conclusion:IL-22 could alleviate liver IRI in rats, and the mechanism may be related to the activation of STAT3 and Nrf2/HO-1 signaling pathway and anti-oxidative stress.

RESUMO

Objective To investigate the diagnosis, surgical treatment and surgical results of infantile left subclavian ar-tery combined with Kommerell diverticulum.Methods In our hospital from 2014 to 2017, there were 15 cases of left subclavi-an artery combined with Kommerell diverticulum, 10 males and 5 females, average age 11.8 months(2 to 48 months), average weight of 9.2kg(4 -24 kg), including 3 cases with ventricular septal defect ( VSD), and 1 cases of coarctation of aorta (COA).Children with postoperative respiratory difficulty, recurrent respiratory infection, chronic cough and other respiratory symptoms, preoperative detection of airway and or esophagus compression performance after cardiac computed tomography ex-amination confirmed, general anesthesia, thoracotomy or left chest lateral thoracotomy, cut off arterial ligaments and Kommerell diverticulum Resection and vagal left subclavian artery transplantation were performed in the left common carotid artery com-bined with cardiac malformation.Results All the children were cured and discharged from hospital.The follow-up and mid-term recovery were good.Conclusion Infants with airway and esophageal compression may have aberrant left subclavian artery combined with Kommerell diverticulum , cardiac CT is an effective means to diagnose this disease .Removal of the associated Kommerell diverticulum and transferring the left subclavian artery to the left common carotid artery , as the main operative meth-od has good early prognosis,and may eliminate residual symptoms and late complications .
