Magnetic particle testing, as an efficient non-destructive testing method, has been widely applied in the field of defect detection for precision components. This study reports a case of occupational ultraviolet cataract caused by prolonged exposure of a magnetic particle testing worker to ultraviolet radiation exceeding standard intensity levels. Insufficient awareness of the potential ocular damage caused by long-wave ultraviolet radiation, inadequate provision of protective goggles, and non-compliant occupational hygiene monitoring and health examinations were identified as the primary contributing factors to this case.

ObjectiveTo investigate the epidemiological characteristics of hand, foot, and mouth disease (HFMD) in Baoshan District of Shanghai from 2008 to 2023, and to provide scientific evidence for surveillance and standardized management of HFMD. MethodsCase data for HFMD reported in the China Disease Control and Prevention Information System from 2008 to 2023 were collected. Descriptive epidemiological methods were used to analyze the population characteristics, and the Joinpoint regression models were applied to assess the temporal trends of HFMD in Baoshan District. ResultsA total of 43 853 HFMD cases were reported from 2008 to 2023 in Baoshan District, with a male-to-female ratio of 1.50∶1. The majority of cases were children, among which scattered children and preschool children accounted for 54.67% and 36.58%, respectively, with 88.00% occurring in children under 5 years old. The average annual incidence rate was147.22/100 000 individuals. The pathogen detection rate in 2018 was 58.60% (109/186). Prior to 2020, CoxA16 was the predominant strain, while EV71 was not detected after 2019. ConclusionThe incidence of HFMD in Baoshan District of Shanghai was influenced by multiple factors including the inclusion in the notifiable infectious disease surveillance system, the introduction of EV71 vaccination, and the COVID-19 pandemic timeline. Populations characterized by highly mobility and frequent external contacts were at high risk for HFMD in Baoshan District. The predominant circulating strains had shifted sequentially from EV71 and CoxA16 to CoxA6.

Methods: The cluster of vomiting and diarrhea outbreaks in Baoshan District from 2017 to 2019 were collected, and the basic information and scene of each cluster were summarized. Sample results were collected and descriptive epidemiological methods were used to analyze the epidemiological characteristics of the outbreak. Results: From 2017 to 2019, a total of 100 cluster vomiting and diarrhea events were reported in Baoshan District, including 9 cases caused by Sapovirus, 120 cases of cluster vomiting diarrhea caused by Sapovirus, with an average incidence rate of 2.37%, including 39 laboratory confirmed cases, the epidemic epidemic time was mainly concentrated in September to November, the places were distributed in 4 primary schools and 5 kindergartens, the main clinical manifestations were vomiting (112/120, 93.33%), abdominal pain (27/120, 22.50%), diarrhea (26/120, 21.67%), compared with Norovirus events, the positive rate, vomiting and fever ratios of Zarovirus were lower than those of Norovirus( χ 2=8.32, 4.52, 14.20, P <0.05). Conclusion In school cluster vomiting and diarrhea events, the positive detection rate of Sapovirus is second enteric vinus behind Norovirus, and it s recommended to formulate a prevention and control plan for Sapovirus infection diarrhea to provide a basis for the on site treatment of school cluster vomiting diarrhea events.

Objective: To investigate the effect of single antiepileptic drugs(AEDs) and combination therapy on the effect of seizure after stroke, prognosis and recurrent seizures. Methods: From November 2013 to December 2017, 280 patients with epilepsy and epilepsy that had been included in the epilepsy course and AEDs course for>6 months in Shaoxing Central Hospital were divided into early-onset epilepsy group and late-onset epilepsy group according to the patients' condition, with 140 cases in each group.According to different AEDs treatment regimens, they were further divided into monotherapy group(valproate) and combination therapy group(valproate, oxcarbazepine combined with levetiracetam). Results: The proportion of monotherapy in the early-onset epilepsy group was significantly higher than that of the late-onset epilepsy group, and the proportion of the late-onset epilepsy group was significantly higher than that of the early-onset epilepsy group(χ²=22.857, P<0.0001). The incidence and effectiveness of epilepsy patients after single-agent and combination therapy in the early-onset epilepsy group had statistically significant differences[onset rate: 40.0%(36/90) vs.16.0%(8/50), χ²=8.591, P=0.003; effective rate: 88.9%(80/90) vs.100.0%(50/50), χ²=5.983, P=0.014]. The incidence and effectiveness of single-agent and combination therapy in the late-onset epilepsy group had statistically significant differences [seizure rate: 40.0%(20/50) vs.82.2%(74/90), χ²=25.974, P=0.000; effective rate: 64.0%(32/50) vs.87.8%(79/90), χ²=11.065, P=0.000]. Conclusion The time of post-stroke epilepsy is not related with the site, type and risk factors of stroke; early epilepsy usually manifested partial seizures and had better curative effect of AEDs, and late epilepsy usually manifested overall tonic clonic seizure; there were no obvious difference in curative effect and recurrence rate of early and late epilepsy on single and combined AEDs treatment.

Objective To investigate the clinical application value of endotoxin and (1-3)-β-D glucan detection in the patients with acute pancreatitis(AP).Methods The MB-80 microbiology rapid dynamic detection system was applied to detect the concentration of plasma LPS and (1-3)-β-D glucan in the patients with AP.Then the results were analyzed.Results Among 184 cases of AP complicating peripancreatic abscess and bilateral lung infection,endotoxin G-lipopolysaccharides positive was in 23 cases,the average value was 394.07 pg/mL,the positive rate was 10.87%,and 15 cases of Gram-negative bacterial infection were verified by the microorganism culture.Among 175 cases of AP complicating peripancreatic abscess and bilateral lung infection,67 cases were(1-3)-β-D glucan positive,the average value was 93.22 pg/mL,the positive rate was 38.29%,which were with the positive rate of serum(1-3)-β-D glucan in the non-AP group,the difference was statistically significant(P<0.05),the microorganism culture or smear verified that 22 cases were fungal infection.Conclusion Plasma endotoxin and (1-3)-β-D glucan detection provides the laboratory biological indicator and is conducive to the assessment of AP infection severity and clinical medication.

Objective To study the application value of G-lipopolysaccharides(G-LPS) detection in patients with traumatic brain injury(TBI).Methods From Jan.2013 to Jun.2014,plasma G-LPS of TBI-patients and non-patients in this hospital were detected by using MB-80 microbiology analyzer and compared.Results of pathogenic microbiological detection of G-LPS positive TBI patients were analyzed,and G-LPS levels,detected before and after treatment,were also analyzed.Results G-LPS positive rate of TBI patients(33.33%) was higher than the 13.34% of non-TBI patients(P<0.05).After treatment,G-LPS level in G-LPS positive TBI patients significantly decreased(P<0.05).The common pathogenic bacteria,causing infection in TBI patients,included Acinetobacter bauman,Klebsiella pneumoniae and Escherichia coli,and the most common infection diseases included respiratory tract infections and urinary tract infections.Conclusion G-LPS detection could be used for the early detection of secondary infection in TIB patients,with significance for guiding clinical treatment.

OBJECTIVETo observe the clinical effects of needle-pricking therapy, a newly medical and minimally invasive technique, for functional retrograde ejaculation and to explore its mechanism. Methods Thirty-six patients with functional retrograde ejaculation were randomly divided into an observation group(19 cases) and a control group(17 cases) In the observation group,needle-pricking therapy was used at Guanyuan(CV 4) and bilateral sacral plexus nerve,lumbar 1 nerve and greater occipital nerve stimulating points,once a week. In the control group, midodrine tablets were prescribed orally,three times a day. All the treatment was given for 9 weeks. The clinical effects of the two groups were observed, and the levels of luteinizing hormone(LH), testosterone(Tes) and estra4 diol(E2) were compared between the two groups.

RESULTSThe total effective rate of the observation group was, 89. 47%(17/19), which was better than 47.06% (8/17) of the control group(P<0. 05). The LH and Tes were obviously increased and E2 was decreased compared with those before treatment in the observation group(all P< 0. 01). Tes was raised(P<0. 05) and E2 was apparently declined in the control group(P<0. 01). After treatment, the differences of serum LH and Tes were statistically significant between the two groups(both P<0. 01).

CONCLUSIONNeedle-pricking therapy has advantages for functional retrograde ejaculation probably in that stimulating lumbosacral nerves can strengthen the function of pelvic floor muscles and urethral expansion muscle and regulate sexual gland axis.
