ObjectiveTo understand the status of parasitic infection in the food sold on market in Qingpu District of Shanghai, and to provide an evidence for the development of prevention and control strategies for parasitic infection applicable to Qingpu District. MethodsAquatic products, meat products and other foodstuffs sold on online shops, at farm product markets, supermarkets/foodstores and restaurants were sampled in Qingpu District, Shanghai, during 2015‒2023, based on the administrative division of Qingpu District. The parasitic infection in the food samples were examined using pressing method and digestion for detecting metacercariae in freshwater products and pickled products, using dissection microscopy for Anisakis larvae in seawater products, Taenia cysticercus and Trichinella encysted larvae in meat products. ResultsA total of 1 079 samples of food products were examined during 2015‒2023, with a total parasite infection rate of 13.44%. The total parasite infection rate of freshwater fish products was 3.40% (16/471), and the difference of parasite infection rates between different freshwater fish species was statistically significant (χ²=229.609, P=0.001). The total infection rate of Clonorchis sinensis was 3.18% (15/471), which had been detected in Pseudorasbora parva, Cyprinidae rhodeus, and Carassius auratus, with a positive rate of 77.78% (7/9), 50.00% (5/10) and 3.90% (3/77), respectively. Metorchis orientalis was detected in in Pseudorasbora parva, with a positive rate of 33.33% (3/9). The positive rate of Gnathostoma spinigerum (third-stage larvae) was 0.81%. Paragonimus metacercariae were not detected in the freshwater shrimps and crabs. The infection rate of seawater fish products was 26.46%. The difference of parasite infection rate in seawater fishes was statistically significant (χ²=109.181, P=0.001). A total of 53 pork and beef samples were tested, none was detected with Trichinella larva cysts, Taenia solium metacercariae, and Taenia saginata metacercariae. The total infection rate of pickled yellow mud snail products was 58.11% (43/74). Paragonimus metacercariae was not detected in any of the pickled aquatic product samples. ConclusionThere are different degrees of parasitic infection in freshwater products, seawater products and pickled aquatic products in Qingpu District of Shanghai. The risk of parasite infection from raw or undercooked foods is high. Health education on healthy dietary practices such as throughly cooked food should be strengthened for local residents.

Objective:To investigate the status quo and influencing factors of the somatization of depressive emotions among college students, in order to provide a theoretical basis for the reform of mental health education and the formulation of operable mental health counseling for college students.Methods:Totally 297 college students from two institutions of higher education in Heilongjiang Province were selected by convenience sampling and investigated with the College Student Depressive Emotion Somatization Questionnaire, Attitudes Toward Seeking Professional Psychological Help Scale-Short Form (ATSPPH-SF), and the Type D Personality Scale (DS14) .Results:The total score for the College Student Depressive Emotion Somatization Questionnaire among the 297 students was (28.49±8.07), and the total score for the ATSPPH-SF was (21.98±2.73). Multiple linear regression analysis showed that the influencing factors for the somatization of depressive emotions in college students were professional psychological help-seeking attitudes and whether they had a Type D personality ( P < 0.05) . Conclusions:During university education, there should be a focus on students' personality traits and the positivity of their attitudes toward seeking professional psychological help in order to mitigate the occurrence of adverse psychological issues such as symptoms of depressive somatization.

Objective:To analyse the correlation between depression and hip fracture in the middle-aged and elderly population in the Chinese community.Methods:The study data were obtained from the China Health and Retirement Longitudinal Study (CHARLS) database. A total of 16,831 respondents from 12,400 households in the fourth national follow-up data in 2018 were selected as the research sample. The samples were divided into a training set and a test set at a ratio of 7∶3, and the test set data were used for internal validation. For external validation, 2,337 subjects recruited from the Institute of Orthopaedics, the First Affiliated Hospital of Zhejiang Chinese Medical University from 2018 to 2023 were selected as the survey subjects. The Center for Epidemiological Studies Depression Scale (CESD) was used to assess depression. CESD≥16 points were defined as depression, and CESD<16 points were defined as no depression. Binary logistic regression was used to gradually analyze the correlation between depression and hip fracture after adjusting for different covariates.Results:In the training set, statistically significant differences were observed between patients with and without hip fractures in terms of depression prevalence (χ 2=16.310, P<0.001), age (χ 2=9.417, P=0.009), education level ( P<0.001), marital status ( P=0.019), and place of residence ( P=0.035). In the testing set, statistically significant differences were found in depression prevalence (χ 2=10.130, P=0.001), gender (χ 2=4.368, P=0.037), education level ( P=0.013), and smoking history (χ 2=8.804, P=0.012). In the external validation set, significant differences were noted in depression prevalence (χ 2=337.885, P<0.001), age (χ 2=29.475, P<0.001), and smoking history ( P=0.020). After controlling for demographic characteristics, exercise, smoking and drinking history, binary logistic regression showed that the risk of hip fracture in depressed patients was 1.78 times higher in the training set ( OR=1.78, P<0.001), 2.73 times higher in the testing set ( OR=2.73, P=0.002), and 15.21 times higher in the external validation set ( OR=15.21, P<0.001) than that of non-depressed patients, indicating good internal and external validation results. Conclusion:Depression is an independent risk factor for hip fractures among middle-aged and elderly populations in Chinese communities. Early identification and active intervention for depression in this population can help reduce the risk of hip fractures.

Objective:To study the effects of plan-do-check-action (PDCA) cycle in quality improvement of neonatal resuscitation.Methods:From 2016 to 2020, the clinical data of neonates born in our hospital were analyzed. Neonates born during 2016 to 2017 were pre-PDCA group and neonates born during 2018 to 2020 were post-PDCA group. PDCA quality improvement included step-by-step, high-frequency and low-dose training, strengthening teamwork and adding equipment.Results:A total of 7 728 live-birth neonates were delivered before PDCA with 319 cases (4.1%) of asphyxia. 10 174 live-birth neonates were delivered after PDCA with 422 cases (4.1%) of asphyxia. The asphyxia rates showed no significant difference between the two groups ( P>0.05). The incidences of severe asphyxia before and after PDCA were both 0.8% without significant difference ( P>0.05). The success rates of resuscitation for severe asphyxia before and after PDCA was 27.9% and 44.9%, respectively, and the differences were statistically significant ( P<0.05). The mortality rates within 7 d before and after PDCA were 0.5‰ and 0.1‰ respectively, without significant differences ( P>0.05). Conclusions:The implementation of PDCA cycle and step-by-step, high-frequency, low-dose neonatal resuscitation training can effectively improve the success rate of resuscitation in newborns with severe asphyxia.

The era of tumor treatment has been revolutionized by the advent of immune checkpoint inhibitors. However, while immunotherapy benefits patients, it can also lead to immune-related adverse events that may affect multiple organs and systems throughout the body, potentially even posing a life-threatening risk. The diverse clinical manifestations and onset times of these adverse events further complicate their prediction and diagnosis. The purpose of this paper is to review the clinical characteristics and predicted biomarkers of adverse events related to inhibitors at immune checkpoints, in order to help clinicians evaluate drug risks and early warn adverse events.

Na⁺/H⁺ antiporter (NHX) gene subfamily plays an important role in plant response to salt stress. In this study, we identified the NHX gene family members of Chinese cabbage and analyzed the expression patterns of BrNHXs gene in response to abiotic stresses such as high temperature, low temperature, drought and salt stress. The results showed that there were 9 members of the NHX gene family in Chinese cabbage, which were distributed on 6 chromosomes respectively. The number of amino acids was 513-1 154 aa, the relative molecular weight was 56 804.22-127 856.66 kDa, the isoelectric point was 5.35-7.68. Members of BrNHX gene family mainly existed in vacuoles, the gene structure is complete, and the number of exons is 11-22. The secondary structures of the proteins encoded by the NHX gene family in Chinese cabbage had alpha helix, beta turn and random coil, and the alpha helix occurred more frequently. Quantitative real-time PCR (qRT-PCR) analysis showed that the gene family members had different responses to high temperature, low temperature, drought and salt stress, and their expression levels differed significantly in different time periods. BrNHX02 and BrNHX09 had the most significant responses to these four stresses, and their expression levels were significantly up-regulated at 72 h after treatments, which could be used as candidate genes to further verify their functions.

OBJECTIVE To establish a method for simultaneous determination of zeaxanthin ，β-carotene，β-cryptoxanthin palmitate and zeaxanthin dipalmitate in Lycium barbarum . METHODS L. barbarum was extracted with n-hexane-anhydrous ethanol-acetone-toluene（10∶6∶7∶7，V/V/V/V）by ultrasonic method. High performance liquid chromatography （HPLC）method was adopted. The determination was performed on YMC C 30 column with mobile phase A consisted of methanol-acetonitrile-water （81∶ 14 ∶ 5，V/V/V）and mobile phase B consisted of dichloromethane （gradient elution ）at the flow rate of 1.0 mL/min. The column temperature was set at 20 ℃. The detection wavelength was set at 450 nm，and sample size was 20 μL. Using zeaxanthin as control，the relative correction factors （RCFs）of β-carotene，β-cryptoxanthin palmitate and zeaxanthin dipalmitate were calculated ， and then the content of each component was calculated according to RCFs and compared with the results of external standard method（ESM）. RESULTS The linear range of zeaxanthin ，β-carotene，β-cryptoxanthin palmitate and zeaxanthin dipalmitate were 0.119 4-2.983 8，0.121 7-1.521 6，0.285 9-5.718 8，8.460 5-211.513 3 μg/mL（all R2＞0.999）. RSDs of precision ，repeatability and stability（16 h）tests were all less than 4％. The average recoveries were 103.34％，107.37％，105.64％，96.16％（RSD＜5％，n＝ 9）. The average RCFs of β-carotene，β-cryptoxanthin palmitate and zeaxanthin dipalmitate were 1.109，1.390，1.158. The relative errors of the content determination results by quantitative analysis of multi-components by singer marker （QAMS）and ESM were within ±1％. CONCLUSIONS The established HPLC-QAMS method is accurate and stable ，which can be used for the content determination and quality control of 4 carotenoids in L. barbarum .
