ObjectiveTo screen suitable packaging and storage conditions for small packaged Alismatis Rhizoma decoction pieces, laying the foundation for developing standardized storage, maintenance techniques and determining shelf life. MethodsUsing the accelerated stability test method, the small packaged decoction pieces of Alismatis Rhizoma were placed in polyethylene plastic bags, aluminum foil polyethylene composite bags, and cowhide coated paper bags under temperature of (40±2) ℃ and relative humidity of (75±5)% conditions, the quality testing was conducted at the end of the 0th, 1st, 2nd, 3rd, and 6th month, respectively. Using long-term stability test method, an orthogonal experiment was designed to investigate storage conditions, packaging materials, and packaging methods. At the end of the 0th, 1st, 3rd, 6th, 9th, 12th, 18th, and 24th month, the quality of small packaged Alismatis Rhizoma decoction pieces was tested under different packaging and storage conditions(including 2 packaging methods:vacuum packaging and sealed packaging, 3 storage conditions:room temperature, cool, and modified atmosphere, 3 packaging materials:cowhide coated paper bag, aluminum foil polyethylene composite bag, and polyethylene plastic bag). Then, the G1-entropy weight method combined with orthogonal experiment was used to analyze the quality changes of the decoction pieces under different packaging and storage conditions to identify optimal packaging and storage conditions. The quality testing indicators for Alismatis Rhizoma decoction pieces were expanded beyond those specified in the 2020 edition of the Pharmacopoeia of the People's Republic of China. In addition to the existing indicators(characteristics, moisture content, extractives, and the total content of 23-acetyl alisol B and 23-acetyl alisol C), new indicators including color value, water activity, total triterpenoid content, and alisol B content have been added. ResultsThe accelerated stability test results indicated that the quality of small packaged Alismatis Rhizoma decoction pieces was more stable when packaged in aluminum foil-polyethylene composite materials compared to cowhide-coated paper bags and polyethylene plastic bags. Analysis of the long-term stability test results using the G1-entropy weight method combined with orthogonal experiment revealed that storage conditions had the greatest impact on both raw and salt-processed products, followed by packaging materials, while the packaging method had the least influence. For both types of small packaged Alismatis Rhizoma decoction pieces, modified atmosphere storage demonstrated superior efficacy compared to cool storage or room temperature storage. Storage in aluminum foil-polyethylene composite bags was superior to polyethylene plastic bags or cowhide-coated paper bags. However, the stability of sealed raw products was better than vacuum-packed ones, whereas vacuum-packed salt-processed products exhibited greater stability than their sealed counterparts. ConclusionBased on the results of the quality changes of small packaged Alismatis Rhizoma decoction pieces under different storage conditions, it is recommended that the suitable storage packaging conditions for small packaged raw products are sealed packaging with aluminum foil polyethylene composite bags and controlled atmosphere storage, and the suitable storage and packaging conditions for small packaged salt-processed products are vacuum packaging with aluminum foil polyethylene composite bags and controlled atmosphere storage.

AIM:To investigate the effect of apoptosis stimulation protein 2(ASPP2)on the development of traumatic proliferative vitreoretinopathy(PVR)in a rabbit model.METHODS:A total of 30 New Zealand white rabbits were selected, and the right eyes of all rabbits were inflicted with a scleral penetrating wound of approximately 6 mm. Then rabbits were randomly and evenly divided into experimental and control group. The experimental group received an intravitreal injection of 0.1 mL of ARPE-19 cell suspension transfected with lentivirus-ASPP2, while the control group received an intravitreal injection of 0.1 mL of ARPE-19 cell suspension transfected with negative control lentivirus. At 1, 2, 3, and 4 wk after PVR modeling, a handheld tonometer was used to measure the intraocular pressure. Moreover, fundus photography and ocular ultrasound examination were performed to detect the retinal proliferation. At 4 wk after modeling, hematoxylin-eosin staining was used to observe the morphological retinal changes, and Western blot was used to determine the protein expressions of ASPP2 and the epithelial-mesenchymal transition(EMT)marker Vimentin in the rabbit retinas.RESULTS:At 1, 2, 3, and 4 wk after modeling, there were no significant changes in intraocular pressure within the experimental and control group of rabbit eyes, either before or after PVR modeling, the success rate of PVR modeling in the experimental group was lower than that in the control group(P<0.05), and the retinal proliferation and structural disorder was less severe in the experimental group. At 4 wk after modeling, the retinal protein expression level of ASPP2 in the experimental group was significantly higher than that in the control group(t=3.193, P=0.033), while the Vimentin protein expression level was significantly lower in the experimental group(t=-3.599, P=0.023).CONCLUSION:ASPP2 may be involved in regulating the process of EMT in retinal pigment epithelial cells, thereby delaying the development and progression of traumatic PVR in rabbit eyes.

[Objective] To explore the strategy of blood management in patients with massive transfusion in the frigid plateau region. [Methods] The treatment process of a patient with liver rupture in the frigid plateau region was analyzed, and the blood management strategy of the frigid plateau region was discussed in combination with the difficulties of blood transfusion and literature review. [Results] The preoperative complete blood count (CBC) test results of the patient were as follows: RBC 3.14×1012/L, Hb 106 g/L, HCT 30.40%, PLT 115.00×109/L; coagulation function: PT 18.9 s, FiB 1.31 g/L, DD > 6 μg/mL, FDP 25.86 μg/mL; ultrasound examination and imaging manifestations suggested liver contusion and laceration / intraparenchymal hematoma, splenic contusion and laceration, and massive blood accumulation in the abdominal cavity; it was estimated that the patient's blood loss was ≥ 2 000 mL, and massive blood transfusion was required during the operation; red blood cell components were timely transfused during the operation, and the blood component transfusion was guided according to the patient's CBC and coagulation function test results, providing strong support and guarantee for the successful treatment of the patient. The patient recovered well after the operation, and the CBC test results were as follows: RBC 4.32×1012/L, Hb 144 g/L, HCT 39.50%, PLT 329.00×109/L; coagulation function: APTT 29.3 s, PT 12.1 s, FiB 2.728 g/L, DD>6 μg/mL, FDP 25.86 μg/mL. The patient was discharged after 20 days, and regular follow-up reexamination showed no abnormal results. [Conclusion] Individualized blood management strategy should comprehensively consider the patient’s clinical symptoms, the degree of hemoglobin decline, dynamic coagulation test results and existing treatment conditions. Efficient and reasonable patient blood management strategies can effectively improve the clinical outcomes of massive transfusion patients in the frigid plateau region.

Objective:
To analyze the trends in incidence and mortality of prostate cancer in Ningbo City, Zhejiang Province, so as to provide insights into the prevention and control of prostate cancer.
Methods:
Data of the incidence and mortality of prostate cancer in Ningbo City from 2011 to 2023 were collected through Ningbo Chronic Disease Collaborative Management System. The incidence and mortality of prostate cancer were calculated and standardized by the data from the sixth national population census in 2010 and the Segi's world standard population in 1960. The trends in incidence and mortality of prostate cancer were evaluated using average annual percent change (AAPC).
Results:
A total of 15 411 cases of prostate cancer were reported in Ningbo City from 2011 to 2023, and the crude incidence, Chinese-standardized incidence and world-standardized incidence were 39.62/105, 22.18/105 and 16.49/105, respectively, showing upward trends (AAPC=14.782%, 10.390% and 10.608%, all P<0.05). The Chinese-standardized incidence of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (25.14/105 vs. 19.44/105; AAPC=9.057% and 14.272%, both P<0.05). The crude incidence of prostate cancer in the groups aged 50-<60 years, 60-<70 years, 70-<80 years and ≥80 years showed upward trends (AAPC=11.657%, 14.031%, 10.734% and 5.300%, all P<0.05). A total of 3 739 deaths were reported, and the crude mortality, Chinese-standardized mortality and world-standardized mortality were 9.66/105, 5.23/105 and 3.71/105, respectively, showing upward trends (AAPC=8.458%, 3.620% and 3.602%, all P<0.05). The Chinese-standardized mortality of prostate cancer was higher in urban areas than in rural areas, and both showed upward trends (5.35/105 vs. 5.13/105; AAPC=3.183% and 3.962%, both P<0.05). The crude mortality of prostate cancer the groups ageds ≥80 years showed an upward trend (AAPC=7.482%, P<0.05).
Conclusions
From 2011 to 2023, the incidence and mortality of prostate cancer in Ningbo City showed upward trends. Special attention should be paid to urban residents, and prostate cancer screening should be strengthened among males aged 50 years and older.

Objective:
To evaluate the intervention efficacy of integrated group social skills training on social ability in school age patients with high functioning ASD, so as to provide a reference for improving social skills in children with high functioning ASD.
Methods:
From January 2021 to December 2023, 62 children aged 7-12 with high functioning ASD who visited the Children s Psychiatry Outpatient Department of the Affiliated Kangning Hospital of Ningbo University were recruited, and were randomly divided into a training ( n =31) and a control group ( n =31) by a random number table method. The training group received a 20 week structured group social training program (mental interpretation courses and social courses), while the control group received only conventional treatment. Chinese version of Griffith Empathy Measure Parent Ratings (GEM-PR) and Social Response Scale (SRS) were used to assess the symptoms of social deficits before and after treatment. Emotional face recognition tasks and eye movement trajectories were used to test the characteristics of social visual attention in children with ASD. Group comparison was conducted using t-test and Mann-Whitney U test.
Results:
At baseline, there were no significant differences in GEM-PR score ( t = -1.20 to -0.81), SRS score ( t =-0.36-1.75), emotional face recognition accuracy and reaction time ( t =-0.58-1.85), and eye movement trajectory ( U/t =-1.63-0.29) between the two group ( P >0.05). After intervention, the total GEM-PR score and empathic cognitive factor score of training group [18.00(10.00,24.00),9.00(8.00,13.00)] were significantly higher than those of the control group [12.00(-1.00,18.00),2.00(-2.00,7.00)], and the total SRS score and social cognition, social perception, social communication, social motivation (73.23±14.20, 16.16±2.72, 6.58±2.50, 24.29±5.61, 9.52±3.73) were significantly lower than those of the control group (95.26±15.29, 19.90±2.84, 12.58±2.49,31.94±6.38, 13.74±4.81) ( U/t =-2.38, -4.59; -5.88, -5.29, -9.47, -5.01, -3.87, P <0.05). The overall correct rate of emotional face recognition and the correct rate of angry, fearful and neutral faces recognition in the training group [(81.55±6.62)%,(76.86±12.06)%,(79.61±12.42)%,(94.27±6.26)%] were significantly higher than the control group [(70.55±13.82)%,(62.82±18.77)%,(67.18±18.85)%,(79.60±20.05)%], and the average reaction time [(2 226.70±274.43)ms] was lower than the control group [(2 417.27±324.10)ms] (t=4.00, 3.50, 3.07, 3.89, -2.42, P<0.05). The time to first eye gaze [764.74 (748.64, 793.73) ms] in the training group was significantly lower than that in the control group [810.92 (782.86, 877.42) ms], and the proportion of moderatetohigh intensity attention area in the face [(37.37±1.27)%] was significantly higher than that in the control group [(30.34±1.23)%] (U/t=3.44, 8.89, P<0.05).
Conclusion
Integrated group social training can significantly improve the social communication and empathy ability of high functioning ASD children, increase active attention and recognition ability of faces, and improve mental development of children with ASD.

Data on basic information, disease history, and self-monitoring blood pressure behavior were collected, height and weight were measured to calculate the body mass index (BMI); and blood glucose and lipid levels were measured. Self-monitoring blood pressure behavior was defined as having measured blood pressure at least once in the past three months. Factors affecting self-monitoring blood pressure behavior were identified using a multivariable logistic regression model.
Results:
A total of 12 475 residents were surveyed, including 5 748 males and 6 727 females, with a male-to-female ratio of 1∶1.17. There were 3 855 residents aged 45-<55 years (30.90%) and 5 511 residents who had self-monitoring blood pressure behaviors (44.18%). Multivariable logistic regression analysis showed that the residents who were males (OR=1.167, 95%CI: 1.081-1.261), lived in rural areas (OR=1.430, 95%CI: 1.321-1.547), aged 45-75 years (45-<55 years, OR=1.384, 95%CI: 1.241-1.543; 55-<65 years, OR=1.397, 95%CI: 1.243-1.570; 65-75 years, OR=1.196, 95%CI: 1.049-1.363), had an annual household income ≥30 000 yuan (30 000-<60 000 yuan, OR=1.190, 95%CI: 1.072-1.321; 60 000-<110 000 yuan, OR=1.330, 95%CI: 1.191-1.485; ≥110 000 yuan, OR=1.746, 95%CI: 1.536-1.984), were overweight (OR=1.170, 95%CI: 1.070-1.280) or obese (OR=1.248, 95%CI: 1.120-1.391), were unaware (OR=1.221, 95%CI: 1.103-1.353) or aware (OR=3.937, 95%CI: 3.575-4.335) of having hypertension, were aware of having diabetes (OR=1.538, 95%CI: 1.354-1.749), and aware of having dyslipidemia (OR=1.265, 95%CI: 1.106-1.447) were more likely to have self-monitoring blood pressure behaviors.
Conclusions
Among the residents aged 35-75 years in Jiangsu Province, 44.18% had self-monitoring blood pressure behavior. Gender, place of residence, age, annual household income, BMI, hypertension, diabetes, and dyslipidemia were identified as influencing factors for self-monitoring blood pressure behavior.

8.Trends in disease burden due to childhood asthma from 1990 to 2021 and future projections in China
Chinese Journal of School Health 2025;46(4):573-578
Objective:
To investigate the trends in disease burden due to childhood asthma in China from 1990 to 2021 and to project the disease burden from 2022 to 2035, so as to provide insights into formulation of the control interventions for childhood asthma in China.
Methods:
The prevalent case, agestandard prevalence, disability-adjusted life years (DALYs) and agestandard DALYs rate of children with asthma at ages of 0 to 14 years and their 95% uncertainty interval (UI) in China from 1990 to 2021 were extracted from the Global Burden of Disease (GBD) database. The temporal trends in the disease burden of childhood asthma were evaluated with estimated annual percentage change (EAPC) and its 95% confidence interval (CI), and the disease burden due to asthma was projected among children at ages of 0 to 14 years in China using a Bayesian age-period-cohort (BAPC) model from 2022 to 2035.
Results:
There were 9.368 3 million (95%UI=6.410 7 million to 14.026 1 million) prevalent cases of asthma among children at ages of 0 to 14 years in China in 2021, contributing to 0.387 9 million (95%UI=0.216 1 million to 0.668 8 million) DALYs loss. The prevalent cases and DALYs of asthma decreased by 37.28% and 52.55% among children at ages of 0 to 14 years in China in 2021 compared with 1990, and the agestandardized prevalence [EAPC=-0.70%, 95%CI=-1.26% to -0.13%)] and DALY rates [EAPC=-1.71%, 95%CI=-2.32% to -1.10%)] also appeared a tendency towards a decline. From 1990 to 2021, the prevalent cases, prevalence, DALYs and DALYs rate of asthma were all higher among male children than among female children, and the disease burden of asthma was higher among children at ages of 5 to 9 years than at other age groups. BAPC model predicted a decline in both prevalent cases and DALYs of asthma among children at ages of 0 to 14 years in China from 2022 to 2035, with 6.759 6 million prevalent cases and DALYs of 0.228 4 million personyears in 2035, while the prevalence and DALYs rates were projected to rise to 5 143.35/105 and 173.75/105 in 2035.
Conclusions
Despite a reduction in the disease burden of asthma among children at ages of 0 to 14 years in China from 1990 to 2021, the prevalence remained high. The disease burden due to asthma is projected to appear a decline among children at ages of 0 to 14 years in China from 2022 to 2035; however, the prevalence and DALYs rates still rise. Intensified control measures and targeted interventions are required to reduce the disease burden of childhood asthma.

Chinese Journal of School Health 2025;46(9):1307-1311
Objective:
To compare the effects of high intensity interval training (HIIT) exercise prescription based on machine vision and routine on HIIT the physical and mental health of female college students with simple obesity, so as to provide a basis for the development of weight loss intervention plans for this population.
Methods:
From August 2023 to February 2024, 115 female college students with simple obesity, selected from Lianyungang Vocational and Technical College and East China Normal University, were randomly divided into a control group ( n =57) and an observation group ( n =58) according to a random number table. The control group received routine HIIT, while the observation group received machine vision based on HIIT exercise prescription (including image acquisition module, image processing module, database management module, backend computer processing and feedback, intelligent evaluation module, which could be customized according to the subjects preferences, providing exercise prescription based on the selected training program and supervised its standardized completion of the training plan). Both were intervened for 12 weeks, 30 minutes each time, once every 2 days, and rest every Sunday. The t-test was used to compare body shape, glucose and lipid metabolism, cardiopulmonary function indicators, anxiety and depression states between two groups before and after intervention.
Results:
Before intervention, there were no statistically significant differences in physical and mental health status indicators between two groups of female college students ( t =0.13-0.86, all P >0.05). After intervention, body mass indexes, waist hip ratios, body fat percentage, fasting plasma glucose, 2hour postprandial plasma glucose, hemoglobin A1c, triglycerides, total cholesterol, lowdensity lipoprotein cholesterol (LDL-C), anxiety and depression scores were all reduced in both groups ( t-observation =-6.94 to -12.92, t-control =-2.71 to -10.95 ), of which the observation group [(23.46±2.18)kg/m 2, 0.70±0.06, (28.03±3.16)%, (4.55±0.67)mmol/L, (6.03±0.74)mmol/L, (5.10±0.70)%, (1.63±0.31)mmol/L, (4.24±0.58)mmol/L, (2.45±0.43)mmol/L, 35.28±4.76, and 33.03±4.03] were lower compared with the control group [(26.54±2.32)kg/m 2, 0.77±0.06, (30.74±4.38)%, (5.03±0.76)mmol/L, (6.62±0.82)mmol/L, (5.82±0.73)%, (1.98±0.35)mmol/L, (4.95±0.61)mmol/L, (2.88±0.47)mmol/L, 39.18±5.04, and 37.25±4.16] ( t =-7.34, -6.26 , -3.81, -3.59, -4.05, -5.40, -5.68, -6.40, -5.12, -4.27, -5.53)(all P <0.05). After intervention, high density lipoprotein cholesterol, stroke volume, left ventricular ejection fraction, maximum oxygen consumption, volume of tidal, and vital capacity increased in both groups ( t-observation =7.43-18.23, t-control =3.89-10.13), of which the observation group [(1.49±0.22)mmol/L, ( 72.35± 4.69)mL, (68.95±5.10)%, (36.97±3.22)mL/(kg ·( min), (25.29±4.11)mL/(kg · ( min), and (3 374.26±169.54)mL] were higher compared with the control group [(1.23±0.20)mmol/L, (67.32±4.06)mL, (64.83±5.05)%, (33.24±3.14)mL/(kg · ( min), (23.01± 3.58 )mL/(kg · ( min), and (3 197.50±125.81)mL] ( t =6.63, 6.15, 4.35, 6.29, 3.17, 6.34)(all P <0.05).
Conclusion
HIIT exercise prescription based on machine vision has better effects than routine HIIT on impoving the body shape, glucose and lipid metabolism, cardiopulmonary function of female college students with simple obesity, and also their mental health.

ObjectiveTo investigate the antidepressant effects and mechanisms of total flavonoids from Cuscutae Semen (TFCC) in the mouse model of chronic unpredictable mild stress (CUMS). MethodsFifty male 4-week-old ICR mice were randomized into five groups (n=10 per group): blank control, model, Cuscutae Semen decoction (10.2 g·kg-1·d-1), paroxetine (2.6 mg·kg-1·d-1), and TFCC (173.2 mg·kg-1·d-1). The other groups except the blank control group underwent chronic unpredictable mild stress (CUMS) for 4 weeks. Behavioral assessments were conducted post-modeling. Then, the model group received distilled water (10 mL·kg-1·d-1), while treatment groups were administrated with respective agents via oral gavage (10 mL·kg-1) for 4 weeks. Depression-like behaviors were evaluated by the sucrose preference test (SPT), forced swimming test (FST), and tail suspension test (TST). Hippocampal neuronal morphology was observed via hematoxylin-eosin staining, and apoptosis in the brain tissue was assessed via terminal- deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL). Enzyme-linked immunosorbent assay (ELISA) was employed to measure the hippocampal levels of inflammatory cytokines [interleukin (IL)-1β, IL-6, and TNF-α)] and neurotransmitters [5-hydroxytryptamine (5-HT), dopamine (DA), and brain-derived neurotrophic factor (BDNF)], while the reactive oxygen species (ROS) levels were quantified via the DCFH-DA probe. Real-time PCR was performed to measure the mRNA levels of NOD-like receptor protein 3 (NLRP3), apoptosis-associated Speck-like protein containing a CARD (ASC), cysteinyl aspartate-specific proteinase-1 (Caspase-1), IL-1β, and inducible nitric oxide synthase (iNOS). Western blot was employed to evaluate the protein levels of NLRP3, ASC, Caspase-1, uncoupling protein 2 (UCP2), and thioredoxin-interacting protein (TXNIP). ResultsCompared with the blank control group, the model group exhibited weight loss (P<0.01), reduced sucrose preference (P<0.01), prolonged immobility time in FST and TST (P<0.01), neuron disarrangement with nuclear pyknosis in hippocampal CA3 region, increased apoptosis in the brain tissue, elevated levels of IL-1β, IL-6, and TNF-α (P<0.01), declined levels of 5-HT, DA, and BDNF (P<0.01), increased ROS accumulation (P<0.01), upregulated mRNA levels of NLRP3, ASC, Caspase-1, IL-1β, and iNOS (P<0.01), down-regulated protein level of UCP2 (P<0.01), and up-regulated protein levels of NLRP3, ASC, Caspase-1, and TXNIP (P<0.01). Compared with the model group, the interventions restored sucrose preference (P<0.01), shortened immobility time (P<0.01), repaired hippocampal neuronal structure, reduced apoptosis, lowered the levels of inflammatory cytokines (P<0.01), restored the levels of neurotransmitters (P<0.01), alleviated ROS accumulation (P<0.01), downregulated the mRNA levels of NLRP3, ASC, Caspase-1, IL-1β, and iNOS (P<0.01), upregulated the protein level of UCP2 (P<0.01), and reduced the protein levels of NLRP3, ASC, Caspase-1, and TXNIP (P<0.01). Moreover, TFCC outperformed Cuscutae Semen decoction in ameliorating depressive behaviors. TFCC excelled in neuronal repair, neurotransmitter regulation, anti-inflammatory effects, and modulation of the UCP2/TXNIP/NLRP3 pathway (P<0.05). ConclusionTFCC modulates the hippocampal UCP2/TXNIP/NLRP3 pathway to inhibit inflammasome activation, reduce oxidative stress, restore neurotransmitters, thus suppressing neuronal apoptosis and promoting the rearrangement and morphology recovery of hippocampal cells. It outperforms Cuscutae Semen decoction in the antidepressant efficacy.
