RESUMO
Marine microorganisms, especially marine fungi, have historically proven their value as a prolific source for structurally novel and pharmacologically active secondary metabolites (Deshmukh et al., 2018; Carroll et al., 2022). The corals constitute a dominant part of reefs with the highest biodiversity, and harbor highly diverse and abundant microbial symbionts in their tissue, skeleton, and mucus layer, with species-specific core members that are spatially partitioned across coral microhabitats (Wang WQ et al., 2022). The coral-associated fungi were very recently found to be vital producers of structurally diverse compounds, terpenes, alkaloids, peptides, aromatics, lactones, and steroids. They demonstrate a wide range of bioactivity such as anticancer, antimicrobial, and antifouling activity (Chen et al., 2022). The genetically powerful genus Emericella (Ascomycota), which has marine and terrestrial sources, includes over 30 species and is distributed worldwide. It is considered a rich source of diverse secondary metabolites with antimicrobial activity or cytotoxicity (Alburae et al., 2020). Notably, Emericella nidulans, the sexual state of a classic biosynthetic strain Aspergillus nidulans, was recently reported as an important source of highly methylated polyketides (Li et al., 2019) and isoindolone-containing meroterpenoids (Zhou et al., 2016) with unusual skeletons.

Objective: To explore the effects of sensory integration training on the behaviors and cognition in children with attention deficit hyperactivity sorder (ADHD) . Methods: Fifty-two children with ADHD (experimental group) were undergone sensory integration training for 60 times and their behaviors were evaluated with the Corners Parents Symptom Questionnaire (PSQ), and the cognition function was determined with the Combined Raven's Test (CRT) and Wisconsin Card Sorting Test (WCST) before and after the training. Another 52 healthy volunteers were recruited as controls and given the corresponding tests described above for comparison of the results. Results: The scores of conduct disorder, compulsion, hyperactivity and hyperactivity index in children with ADHD were decreased significantly than those of controls after training [(0.60 ± 0. 34) vs. (0.68 ± 0.35), (0.92±0.57) vs. (1.25±0.70), (0.82±0.29) vs. (1.08±0.44); P<0.05] .Inaddition, the improvement was found in IQ, categories control, and conceptive level as compared with that before the training [such as IQ, (105. 37 ±22.76) vs. (97. 37 ±24.15); P<0.001], whereas the scores of response error, response error percentage, first category and persistent errors were decreased after the training [such as response error, (39.40 ± 22.22) vs. (46.60 ±23.44), P<0.001] . For the experimental subjects, the scores in the first response number and the persistent errors percentage right after the training were higher compared with the controls [(12.03 ±5.08) vs. (10.65±0.84), (50.75 ±18.35) vs. (39.95 ± 15. 34); Ps<0.05] .Conclusion: The sensory integration training can improve the behaviors and cognition in children with ADHD, but it produces fewer effects on some of the executive functions despite clinical symptom relief to a certain extent.
RESUMO
OBJECTIVE To analyze the quality of the disposable sterile medical appliances befoure used and give suggestions for managements.METHODS The acceptance process of the disosable sterile medical appliances during the past five years wes restropectively analyzed and the unqualified products were found out.RESULTS After examination of the sterile medical devices,the main problems were more ethylene oxide residues,packaging damaged,expiry date not clear,both within and outside the Model not matching the registration of medical device product number.Categories not matching the product and so on.CONCLUSIONS The above problems are not meet the national laws and regulations,and should be timely and effective monitored to achieve safety use of medical device.
RESUMO
In order to investigate the effects and mechanisms of calcium dobesilate on renal lesions in experimental type 2 diabetic rats, dibetic rats were randomly divided into control group (group C) and experimental group (group D) treated with calcium dobesitate. The serum creatinine (Scr),protein kinase C (PKC), creatinine clearance (Ccr), transforming growth factor-beta1 (TGF-βi),type Ⅳ collagen were compared among the groups after 24 weeks. The renal tissues were observed under light microscopy and electron microscopy. The results showed that after 24 weeks, Scr,PKC, TGF-β1 in group D were significantly lower than in group C, meanwhile, renal pathologic changes in group D were improved. Ccr had no difference between group C and group D. It was concluded that calcium dobesilate could ameliorate renal lesions in diabetic rats through inhibiting PKC and TGF-β1.
RESUMO
Objective To evaluate the veracity and consistency of the results obtained from three automated hematology an-alyzers. Methods The reproducibility tests were used to assess the precision,the verification tests were exerted to evaluate the accuracy and consistency of test parameters(WBC,RBC,Hb,Hct and Plt) of the three hematology analyzers. According to the 1/2 standard of American Clinical Laboratory Improvement Amendment (CLIA,88),the relative bias of the reference analyzer and other assessed analyzers were determined. Results The results obtained from the three analyzers showed ex-cellent precision and stability,the coefficients of variation (CV) were all less than 5%; compared with the results of LH750,the results of Gens 5diff and ACT-5diff showed excellent correlation,all coefficients of correlation(?) exceeded 0.975. The results of both RBC and Hct obtained from Gens 5diff and ACT-5diff exceeded allowable error; the results of WBC,Hb and Plt were in the allowable error range. Conclusion In the condition of the excellent precision and stability,system errors existed in the analyzer can be found by verification on time. Through being adjusted and calibrated,the hematology ana-lyzers can meet the requirements and these results are consistent.
RESUMO
Hyperprotein chow can increase perfusion and filtration of glomerulus,and so result in kidney hypertrophy and damage.Monocytes and macrophages are considered to be a characteristic of diabetic nephropathy(DN),and play a key role in the glomerular sclerotic lesions.At present,hyperprotein chow,infiltration of monocytes and macrophages and overproduction of intercellular adhension molecule-1(ICAM-1) are thought to be involved in the progression of DN.Hyperprotein chow resulting in hyperfiltration may be one of potential mechanisms of ICAM-1 upregulation.
RESUMO
High-efficiency exhalation disinfection device for the patient infected with SARS can also meet the disinfection requirements of the patients with severe respiratory communicable diseases. Connected with the exhaust vent of the breathing mask or the respirator by corrugated tubes, this device gathers exhalation containing a large amount of causative agents through the completely leakproof ductwork and then expels purified air after multiplicate disinfection by high temperature, high pressure and chemical disinfectant. The device can prevent the patient with severe respiratory communicable disease from polluting their surrounding air and thus cut off the route of transmission, reduce the infection rate and the death rate of the person and medical personnel who has made intimmate contact with the patient.
