Background Age-related cataract is the leading cause of visual impairment worldwide.To seek the effective prevention and drugs for management of cataract is important.Naphthalene-induced cataract of rat is an ideal animal model for the research of human age-related cataract,and aspirin has been proven to inhibit the development of human age-related cataract.ObjectiveThe present study is to investigate the role of aspirin on naphthalene-induced cataract.Methods Forty-five 150-160 g female SD rats were divided into three groups randomly.Naphthalene was orally taken with 0.5mg/kg per day for 3 days and then 1mg/kg per day for 70 days,and then 100mg/kg of aspirin was given per day for 70 days following four-day washout period in group A.In group B,the animals was given orally only naphthalene at the same way.No any intervention was used in group C.Naphthalene-induced cataract was examined under the slim lamp every week.The experimental animals were sacrificed and lenses were obtained in 70 days.α-Crystalline was extracted from lens homogenate and purified and identified using High Performance Liquid Chromatography(HPLC),2-dimentional electrophoresis gel and Western blot.Different abilities of α-crystalline to protect β low crystalline from aggregation were observed using ultraviolet spectrophotometer.Results Naphthalene-induced cataract formed at the third week in only naphthalene group but at the sixth week in naphthalene+aspirin group under the slim lamp.No significant difference was found in the degree of lenses opacity in the second week among these three groups(F=0.032,P=0.969).However,a statistically significant difference was seen in the degree of lenses opacity in the fourth,sixth,eighth and tenth week among these three groups(F= 5031.130,P=0.000;F=115964.000,P=0.000;F=169846.500,P=0.000;F= 195431.200,P=0.000).Themolecular chaperone-like activity was significantly higher than that of the naphthalene-induced group.Conclusion Aspirin delays the progression of lens opacification through protecting α-crystalline molecular chaperone-like activity.

Background Previous study on critical period plasticity in local cortical circuits primarily was only to test the role of some proteins in visual cortex on visual development based on the existed neural signals expression system,but whole containing proteins analysis in cortical circuits is lack.To perform a whole containing proteins analysis has an important significance for critical period plasticity study.Objective This study was to investigate the influence of dark rearing on visual sense and proteomics in visual cortex for growing rat.Methods Two SD female rats were fed in two cages together with 12 newborn rats on the same day respectively,and half number of newborn rats were exchanged each other from first day after delivering and marked by eartipping.The newborn rats in a cage were bred in the dark environment for 40 days,and newborn rats in other cage were bred in the nature environment as controls.The blink response of rats to nearby object was examined and compared between the two groups of rats.Then three rats from two cages were sacrificed respectively and bilateral primary visual cortex tissue was isolated.Proteomics in rat primary visual cortex was detected by two-dimensional electrophoresis and mass spectrometry and the result was checked from database.Then the survival rats in the dark environment returned to the nature environment for 10 days,and the blink response of rats to nearby object were compared with that of agematched rats in the natural environment.The use and care of experimental rats followed the instruction of Ethic Committee of Nankai University.Results The blink response of rats was (0.33 ± 0.35) times in the dark environment for 40-day group,and that in the natural environment for 40-day group was (6.42±0.68) times,with a significant difference between them (t =24.38,P＜0.01).After returned to natural environment for 10 days,the blink response times of rats were less than those of the natural environment group ([5.00±1.22] times vs.[6.11±0.59]times),but this change was not statistically significant (t =2.09,P＞0.05).Two-dimensional electrophoresis and mass spectrometry assay revealed that 36 different proteins in visual cortex were found in the dark-feed rats compared with the natural environment rats,including 26 loss proteins and 10 extra proteins.Among the different proteins,Eps 15 homology domain-containing protein-3 (EHD3),tubulin alpha-1A chain and 2 ',3 '-cyclic-nucleotide 3 ' phosphordiesterase were the known proteins.Conclusions Dark rearing cause reversible visual loss in critical period plasticity newborn rat,and the change of proteomics in visual cortex is probably an affecting factor.

UDP glucosyltransferase (UDPGT) catalyzes the synthesis of secondary metabolites and plant hormones to regulate plant growth and development, pathogen defense and environmental adaptability. In this study 18 members of the RcUDPGT gene family were cloned from Tibetan Rhodiola crenulata and analyzed using bioinformatics. The tissue-specific expression, abiotic stresses and plant hormones (abscisic acid, auxin, methyl jasmonate) induced expression patterns were identified by real-time quantitative PCR. The bait vector of RcUDPGT (JX228125.1) was constructed to select interacting proteins from an Arabidopsis yeast library. The results of the bioinformatics analysis revealed that RcUDPGT nucleotide sequences were about 1 400 bp and encoded 452-498 amino acids. In the primary protein sequences, C-terminal sequences were more conserved compared with N-terminal regions, which held a PSPG (plant secondary product glycosyltransferase) domain. In the tertiary structures, RcUDPGTs contained a UDP sugar donor recognition binding site. In addition, all genes had multiple phosphorylation sites. The results of qRT-PCR showed that RcUDPGTs genes were expressed in root, stem and leaf. The expression levels were regulated by low temperature/ultraviolet light and various plant hormones (ABA, IAA, MeJA), but the expression patterns were quite different among them. For example, RcUDPGT6, RcUDPGT11, and RcUDPGT17 had the highest expression in leaves and were induced by all three hormones, suggesting that the functions of these genes might be to respond to environmental changes. RcUDPGT9, RcUDPGT10, RcUDPGT14 were most abundantly expressed in roots and were significantly induced by ABA and MeJA hormones, indicating that these genes may be involved in the synthesis and accumulation of salidroside. Yeast two-hybrid results showed that RcUDPGT did not exhibit autoactivation and cell toxicity, and two significant interactional genes were identified, AtKCR1 (AT1G67730.1) and AtSNL4 (AT1G70060). The AtKCR1 gene encodes a β-ketoacyl reductase (KCR) involved in synthesis of very long chain fatty acids. The AtSNL4 gene encodes a homolog of the transcriptional repressor SIN3, which could participate in the ABA hormone signaling pathway and enhance the transcriptional repression of AP2/EREBP class factors in Arabidopsis. These results suggest that the accumulation of the secondary metabolite salidroside in Rhodiola crenulata might be affected by several regulatory mechanisms. The above results may lay the foundation for understanding the adaptive mechanism of Rhodiola crenulata in a high altitude environment and stimulate an in-depth study of the synthesis and accumulation of secondary metabolites in this species.

Abstract: Objective　To investigate the clinical and laboratory characteristics of pulmonary infection caused by Nocardia otitidiscaviarum. Methods　The clinical data of a patient with pulmonary infection caused by Nocardia otitidiscaviarum were reported, and the clinical characteristics, laboratory characteristics and drug sensitivity of pulmonary infection caused by Nocardia otitidiscaviarum were summarized in combination with the relevant literature at home and abroad from January 2010 to December 2022. Results　A 67-year-old female patient was admitted to the hospital on June 30, 2020 because of "repeated chest tightness and shortness of breath for 3 years, aggravated cough, expectoration and fever". The sputum, alveolar lavage fluid and blood of the patient were collected for culture, and the detected pathogenic bacteria were identified. There are pathogenic bacteria growing in sputum and alveolar lavage fluid, which are identified as Nocardia otitidiscaviarum by Autof ms mass spectrometer. According to the results of pathogenic bacteria and the patient's condition, meropenem combined with compound sulfamethoxazole tablets were given anti-infection treatment, and the patient's condition improved and discharged. Conclusion　The clinical manifestations and imaging features of nocardiosis are lack of specificity, and are prone to misdiagnosis and missed diagnosis. Etiology is the key to disease diagnosis, and clinical examination and culture should be conducted in time.

Objective To evaluate the therapeutic efficacy of a combination of proton pump inhibitor(PPI) and hydrotalcite for endoscopic submucosal dissection (ESD) induced ulcer.Methods Eightyone consecutive patients who underwent ESD were randomly assigned to either the group of PPI and hydrotalcite therapy ( drug combination group,n =41 ) or the PPI group ( n =40).Delayed bleeding rates were monitored and compared.The main upper abdomen symptoms 1-wk later and ulcer healing rates and ulcer diameter 4-wk later were compared between the two groups.Results There was no significant difference in delayed bleeding rate (P ＞ 0.05 ).At the end of first week after ESD,the combination therapy was significantly more effective than the PPI alone in reducing frequencies and severity of upper abdominal pain and upper abdominal distention,while there was no significant difference between the two groups in relieving belch and nausea.A better ulcer healing rates and a smaller ulcer diameter were observed in the combination group at the end of 4 weeks ( P ＜ 0.05 ).Conclusion The combination therapy of hydrotalcite and PPI can relieve upper abdominal symptoms and improve the healing rate of ESD induced ulcer.
