Autism spectrum disorder(ASD)is a severe neurodevelopmental disorder with onset in child-hood,characterized by persistent social communication deficits and restricted,repetitive patterns of behavior.In recent years,its global prevalence has shown a continuous upward trend.However,there remains a lack of effective treatments capable of improving brain function in ASD.This article systematically reviews the mechanisms,clinical efficacy,and safety of HBOT in ASD,while exploring its potential therapeutic value.Research indicates that HBOT exerts its effects through the following mechanisms:enhancing plasma oxygen saturation,thereby improving oxygen supply to ischemic brain regions;inhibiting microglial activation,reducing pro-inflammatory cytokine levels;modulating gut microbiota homeostasis,restoring brain-gut axis dysfunction.Clinical studies demonstrate that when HBOT is combined with Applied Behavior Analysis(ABA),it significantly reduces behavioral scale scores in children with ASD while improving their social interaction,self-care abilities,and verbal communication.Additionally,HBOT positively regulates oxidative stress markers and enhances perfusion in specific brain regions.Regarding safety,strict adherence to operational protocols minimizes the risk of adverse effects(e.g.,baro-trauma).This review provides evidence-based support for the standardized application of HBOT in ASD.Future re-search should focus on optimizing treatment protocols(e.g.,pressure and oxygen concentration parameters)and evaluating long-term efficacy.

This paper briefly described the present state of the use of major medical equipment in an island hospital. The intermittent idleness of the equipment increased the difficulty of maintenance. The gap between the current medical and equipment preparation, such as reagents, instruments, and equipment, and the demand for medical support was a major obstacle for diagnosis and treatment. Harsh climate, incomplete hospital information system, and poor handover process of medical staffs during rotation were the main challenges for medical equipment management in remote island hospitals. It is suggested that the island hospital improve its management regulation of medical instruments and equipment, ensure sufficient stock of key equipment and reagents, establish a regional medical consortium model to make full use of remote consultation and artificial intelligence in medical imaging, and make reasonable use of hospital ships to balance and coordinate medical resources for island hospitals, so as to effectively improve the medical support capacity on islands.

Objective To investigate the clinical value of the combined detection of Golgi protein 73 (GP73),alpha-fetoprotein variant-L3 (AFP-L3)and transforming growth factorβ1(TGFβ1)in the early diagnosis of hepatocellular carcinoma (HCC).Meth-ods 48 cases of healthy control,42 cases of hepatitis B,50 cases of posthepatitic cirrhosis and 58 cases of HCC were selected and detected GP73,AFP-L3 and TGFβ1.The detection results were compared among 4 groups.Results (1)The levels of GP73,AFP-L3 and TGFβ1 had statistical differences among 4 groups(P <0.05 );(2 )The positive rate of the 3-marker combined detection reached 96.55%,which was higher than that of the 2-marker combined detection and the single marker detection.Conclusion (1) GP73,AFP-L3 and TGFβ1 may be used as the serum indicators for the early diagnosis of HCC;(2)Compared with the traditional HCC marker AFP,AFP-L3 has relatively high sensitivity and specificity and has the important role in the differential diagnosis of benign and malignant diseases of the liver,which is considered as a better serum marker in the HCC diagnosis;(3)The 3-indicator combined detection can significantly improve the positive detection rate of HCC and has better application value.

OBJECTIVE To study the distribution and drug resistance of pathogens in urinary system,provide the credible evidence with the clinic diagnosis and the treatment of urinary diseases,and give doctors reasonable advice for medicine usage. METHODS The pathogens from the urine specimens were isolated and cultured from the patients in hospital from Jan 2003 to Dec 2004.The total 536 strains of pathogens were identified and the drug resistance was analyzed. RESULTS Escherichia coli among the pathogens infected the urinary system rated the top(57.0%),secondly were Enterococcus,Klebsiella,Staphylococcus,Pseudomonas aeruginosa and fungi.The drug resistance of E.coli to imipenem was the lowest,about 2.6%,however,it was above 30.0% towards the most beta-lactam antibiotics;the drug resistance of Enterococcus was generally higher,about 40.0-70.0%,but vancomycin was lower,about 10.3%. CONCLUSIONS The main pathogens are Enterobacteriaceae which infect the urinary system,the drug resistance is obviously higher to the quinolones,the clinic should reasonably choose the antibiotics according to the test results of the pathogens sensitivity to drugs.
