OBJECTIVE:To investigate the characteristics and regularity of lornoxicam related ADR,and to provide reference for rational and safe use of lornoxicam. METHODS:From Jan. 1,2006 to Dec. 31,2013,lornoxicam related ADR reports collect-ed by National ADR Monitoring System in Beijing were analyzed retrospectively about their characteristics and related factors. RE-SULTS:In the statistical period,there were 48 ADR reports related to lornoxicam. The people over 40 years age accounted for 62.5%. 38 patients used lornoxicam by intravenous infusion or intramuscular injection ,accounting for 79.17%. The clinical mani-festations were diverse and complex,in which skin(32.96%)and gastrointestinal damage(25.00%)were more common ADR oc-curred within 30 min,accounting for 35.42%,and it would be better after stopping drug or 1-3 days symptomatic treatment. CON-CLUSIONS:The rational use of lornoxicam can reduce the occurrence of ADR. Suggestion on the use of the drug,is that the pa-tient should be monitored for security,in order to reduce the risk of ADR.

Non-coding RNAs ( ncRNA ), including ribosomal RNA( rRNA), transfer RNA( tRNA), MicroRNA ( miRNA), long noncoding RNA(lncRNA) and small nucleolar RNA(snoR-NA), are a class of RNA that have multiple functions and are not translated to proteins. MicroRNA and lncRNA are involved in the injury, remodeling and aging of blood vessels, and it is necessary to understand the regulatory roles of MicroRNA and lncRNA in these processes. It is reported that MicroRNA and lncRNA are not only participated in the regulation of oxidative response, inflammation, cell proliferation and migration, and phenotype transition, they are also involved in the regulation of gene expression by conducting different mechanisms, including transcriptional regulation, post-transcriptional modification and chromatin remodeling. These aspects of regulation by MicroRNA and lncRNA are related to cardiovascular diseases, such as ath-erosclerosis, hypertension, myocardial infarction, stroke, pul-monary hypertension and diabetes, and thus provide a new way for genetic diagnosis and therapy of cardiovascular diseases.

Objective To investigate the status of nutritional risk and nutritional support in general surgery patients, and to explore their association with postoperative complications and length of hospital stay.Methods From January 2014 to February 2015, 853 inpatients in general surgical wards in the Second Hospital of Hebei Medical University were enrolled.Nutritional Risk Screening 2002 (NRS 2002) was used to estimate nutritional status of patients.The patients were divided into 2 groups based on whether they received nutritional support.The length of hospital stay in days and postoperative complications were recorded.The association of nutritional risk and nutritional support with complications and length of hospital stay were analyzed.Results In the 853 surgery patients, the prevalence of nutritional risk was 31.1％ (265/853) and that of malnutrition was 5.4％ (46/853).The incidence of postoperative complications was 14.2％ (121/853).The patients with nutritional risk had a significantly higher incidence of postoperative complications compared to those without nutritional risk [29.8％ (79/265) vs.7.1％ (42/588) , P ＜ 0.000] , and a longer hospital stay [(12.5 ±6.4) days vs.(4.2 ±3.9) days, P ＜0.001].In the 853 patients, 27.3％ (233/853) received nutrition support.In the patients with nutritional risk, those on nutritional support had a significantly lower incidence of complications compared with those not on nutritional support [16.7％ (32/192) vs.64.4％ (47/73), P＜0.05] and shorter hospital stay [(7.5±4.6) days vs.(16.3±8.5)days, P ＜ 0.05].Conclusions According to NRS 2002 result, a fairly high percentage of general surgery patients may have nutritional risk.Patients with decreased body mass, less dietary intake, and at higher age may be more likely to have nutritional risk.Nutritional risk may be associated with a higher incidence of postoperative complications and longer hospital stay.Patients at nutritional risk appear to be more likely to benefit from nutritional support.

Objective To investigate the prevalence of mutation in the locus 306 of embB gene in multi-drug resistant (MDR) Mycobacterium tuberculosis (TB) and evaluate the prospects for using it as a molecular marker to detect MDR-TB.Methods The 291 strains enrolled in this study were from the reference laboratory of Shanghai municipal centers for disease control and prevention, all of which had been tested for drug susceptibility.Mutation in embB 306 was screened both by amplification refractory mutation system (ARMS) and DNA sequencing.The mutation frequencies of embB 306 in the sample groups varied in drug resistance were statistically analyzed.Results 38(51.4% ) of the 74 MDR-TB were embB 306-mutant (X2 =93.8,P＜0.01).Of the 24 TB resistant to at least two drugs but not MDR, 9(37.5% ) were embB 306 mutant (X2 =60.1 ,P＜0.01 ).But only two(4.9% ) embB 306-mutant strains were found in 41 strains resistant to only one drug (X2 =6.8,P=0.0093).None embB 306-mutant strains were found in 152 pansensitive strains.The specificity of using embB 306 as a molecular marker for detecting multi-drug resistant TB was 94.9% (206/217).Conclusions As a molecular marker for screening drug resistant TB,especially MDR-TB, the gene locus embB 306 shows a relatively high sensitivity and specificity, promising a sound future for its application in clinics to realize fast screening of patients infected with MDR-TB and to provide evidence for appropriate medication.

Objective:The present study was aimed to evaluate the nutritional risk using nutritional risk screening 2002 (NRS2002) score and to investigate the impact of nutrition support on clinical outcome in hospitalized patients.Methods:Six hundred and ninety four hospitalized patients were recruited.NRS 2002 was applied to evaluate the nutritional risk of patients.Meanwhile,the effect of nutrition support on complication rate was evaluated between different types of patients.Results:14.0％ of patients had malnutrition and the incidence of nutritional risk was 27.5％.Patients with nutritional risk had a higher complication rate (P ＜0.01).Totally,22.0％ (153/694) patients received nutrition support,including 81.7％ patients with nutritional risk and 18.3％ patients without nutritional risk.Patients with nutritional risk benefited from nutrition support,as shown by lower complication rate and shorter length of hospital stay.In patients with nutritional risk,complication rate was lower in enteral fed patients compared to parenteral fed patients.Conclusion:With nutritional risk screening,patients' nutritional status can be evaluated and appropriate nutrition support can be performed.Compared to those without nutritional risk,patients with nutritional risk will benefit more from nutrition support,as indicated by lower complication rate and reduced length of hospital stay.

GLKs (GOLDEN 2-LIKEs) are a group of plant-specific transcription factors regulating the chloroplast biogenesis, differentiation and function maintains by triggering the expression of the photosynthesis-associated nuclear genes (PhANGs). The GLKs also play important roles in nutrient's accumulation in fruits, leaf senescence, immunity and abiotic stress response. The expression of GLK genes were affected by multiple hormones or environmental factors. Therefore, GLKs were considered as the key nodes of regulatory network in plant cells, and potential candidates to improve the photosynthetic capacity of crops. Since numerous researches of GLKs have been reported in plants, the biological function, molecular mechanism of GLKs genes and its applications in breeding were summarized and a GLK-mediated signaling network model was developed. This review may facilitate future research and application of GLKs.

OBJECTIVE To evaluate the post-marketing safety of Compound porcine cerebroside and ganglioside injection in patients with ischemic stroke. METHODS A drug-induced， prospective， non-controlled clinical study design was conducted. Using the patients with ischemic stroke who received Compound porcine cerebroside and ganglioside injection at least once in 46 secondary class A and above medical institutions across the country from April 2020 to May 2021 as the monitoring objects， and their basic data， medication information and the occurrence of adverse drug reactions were analyzed. RESULTS Among 13 514 patients with ischemic stroke， the incidence of adverse events was 10.01%， and the incidence of adverse reactions related to Compound porcine cerebroside and ganglioside injection was 0.33%. Drug-related adverse drug reactions were mild or moderate， concentrated in the gastrointestinal system （18 cases）， skin and subcutaneous tissue （10 cases）， nervous system （7 cases） and other systems/organs， mainly including constipation， abdominal pain， diarrhea， rash， pruritus， dizziness and other symptoms. Most of the patients （91.03%） recovered or improved after treatment， and 2 patients died. Among the 45 patients with adverse drug reactions， 84.44% were cured or improved after drug withdrawal or symptomatic treatment， and 15.56% had no significant change. The incidence of adverse drug reactions in tertiary hospitals was significantly higher than that in secondary hospitals， and the incidence of adverse drug reactions in patients with allergic history was significantly higher than that in patients without allergic history （P＜0.05）. Irrational drug use was found in 2.76% of patients， and the incidence of adverse drug reactions（2.95%） was significantly higher than that in patients without irrational drug use（0.26%，P＜0.05）. CONCLUSIONS The adverse drug reaction symptoms of ischemic stroke patients treated with Compound porcine cerebroside and ganglioside injection are relatively common， the incidence rate is generally low， and it is related to the patients’ physique and whether the drug use is standardized.

The gut microbiota plays an important role in regulating the pharmacokinetics and pharmacodynamics of many drugs. FLZ, a novel squamosamide derivative, has been shown to have neuroprotective effects on experimental Parkinson's disease (PD) models. FLZ is under phase Ⅰ clinical trial now, while the underlying mechanisms contributing to the absorption of FLZ are still not fully elucidated. Due to the main metabolite of FLZ was abundant in feces but rare in urine and bile of mice, we focused on the gut microbiota to address how FLZ was metabolized and absorbed.

YABBY proteins are important transcription factors that regulate morphogenesis and organ development in plants. In order to study the YABBY of strawberry, bioinformatic technique were used to identify the YABBY gene families in Fragaria vesca (diploid) and Fragaria×ananassa (octoploid), and then analyze the sequence characters, phylogeny and collinearity of the family members. The RNA-seq data and the quantitative reverse transcription-polymerase chain reaction (qRT-PCR) technique were used to assay the expression patterns of the family members. A green fluorescent protein (GFP) was fused with FvYABBYs and transiently expressed in tobacco leaf cells for the subcellular localization. As the results, six FvYABBY genes and 26 FxaYABBY genes were identified from F. vesca and F.×ananassa, respectively. The FvYABBY genes were grouped into five clades, and five family members were orthologous with AtYABBY genes of Arabidopsis. In F. vesca, all of the FvYABBYs were basically not expressed not expressed in root and receptacle, while FvYABBY1, FvYABBY2, FvYABBY5 and FvYABBY6 were highly expressed in leaf, shoot, flower and achene. In F.×ananassa, FxaYABBY1, FxaYABBY2, FxaYABBY5 and FxaYABBY6 were expressed in achene, and all FxaYABBY were poorly or not expressed in receptacle. Additionally, under the abiotic stresses of low temperature, high salt and drought, the expression of FvYABBY1, FvYABBY3, FvYABBY4 and FvYABBY6 were down-regulated, FvYABBY5 was up-regulated, and FvYABBY2 was up-regulated and then down-regulated. In tobacco leaf cells, the subcellular localization of FvYABBY proteins were in the nucleus. These results provides a foundation for the functional researches of YABBY gene in strawberry.

The progression of hyperuricemia disease is often accompanied by damage to renal function. However, there are few studies on hyperuricemia nephropathy, especially its association with intestinal flora. This study combines metabolomics and gut microbiota diversity analysis to explore metabolic changes using a rat model as well as the changes in intestinal flora composition. The results showed that amino acid metabolism was disturbed with serine, glutamate and glutamine being downregulated whilst glycine, hydroxyproline and alanine being upregulated. The combined glycine, serine and glutamate could predict hyperuricemia nephropathy with an area under the curve of 1.00. Imbalanced intestinal flora was also observed. , , , , and other conditional pathogens increased significantly in the model group, while and , the short-chain fatty acid producing bacteria, declined greatly. At phylum, family and genus levels, disordered nitrogen circulation in gut microbiota was detected. In the model group, the uric acid decomposition pathway was enhanced with reinforced urea liver-intestine circulation. The results implied that the intestinal flora play a vital role in the pathogenesis of hyperuricemia nephropathy. Hence, modulation of gut microbiota or targeting at metabolic enzymes, , urease, could assist the treatment and prevention of this disease.
