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 0^th， 1^st， 2^nd， 3^rd， and 6^th 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 0^th， 1^st， 3^rd， 6^th， 9^th， 12^th， 18^th， and 24^th 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.

ObjectiveTo establish an adjusted Serfling regression model to estimate the excess cases and the excess epidemic period of hand-foot-mouth disease (HFMD) in Beijing from 2011 to 2019, so as to provide data support and decision-making basis for HFMD prevention and control. MethodsThe weekly number of HFMD cases in Beijing from 2011 to 2019 was utilized for adjusted the Serfling regression model. Then the adjusted model was used to fit the baseline and epidemic threshold of HFMD in Beijing from 2011 to 2019, calculating the excess cases and determining the excess epidemic period. ResultsA total of 279 306 cases of HFMD were reported in Beijing from 2011 to 2019, with the climax of the disease occurring in summer and autumn. After adjusting the fitting R² of the Serfling regression model to 0.773, a total of 10 excess epidemic periods totaling 92 weeks were estimated, mainly occurring in summer. The highest number of excess cases during an excess epidemic period was found in 2014 (1 272 cases, 95%CI: 990‒1 554), accounting for 65.04% of the actual cases (95%CI: 50.62%‒79.46%). ConclusionThe adjusted Serfling regression model fits well and can be utilized for early warning of HFMD and estimating the disease burden caused by HFMD.

ObjectiveTo identify the characteristic exhaled volatile organic compounds （VOCs） associated with postoperative pulmonary complications （PPCs） in patients after abdominal surgery. MethodsThis study prospectively enrolled 76 patients with tracheal intubation who were transferred to intensive care unit （ICU） after abdominal surgery at Peking University People's Hospital between December 10， 2022 and June 30， 2023. The patients' basic information was collected during their perioperative period， and their exhaled VOCs were collected within 24 hours after their admission to the ICU， and then analyzed by gas chromatography and mass spectrometry （GC-MS）. According to whether PPCs occurred 24 hours after surgery， the patients were divided into PPCs group （n=44） and non-PPCs group （n=32）， and the differences of VOCs were compared between the two groups. Lasso regression analysis was used to screen the valuable variables of VOCs， and Logistics regression analysis to determine the characteristic VOCs associated with the occurrence of PPCs. ResultsAmong the 76 patients， 44 had PPCs and 32 had no PPCs. Lasso regression analysis screened 4 PPCs-related compounds from exhaled VOCs of two groups for further analysis and Logistics regression analysis showed that the increase of 1-Hexadecanol content in exhaled breath was significantly correlated with the occurrence of PPCs （OR： 1.000， P=0.002）. ConclusionThis study indicated that the increased content of 1-Hexadecanol in patients' exhaled breath after abdominal surgery may be associated with the occurrence of PPCs.

Objective: To understand classroom environmental conditions and their association with spinal curvature abnormalities among students of primary and secondary schools in Guizhou Province, so as to provide a basis for formulating school health policies and scientific prevention and control measures for abnormal spinal curvature in students. Methods: Using a stratified random sampling method, 471 schools (2 811 classrooms) were selected annually across the province from 2022 to 2024 in order to monitor and evaluate classroom environment according to national standards. Spinal examinations were conducted for 196 606 (2022), 194 876 (2023), and 195 048 (2024) students, and χ 2 test was used to analyze the correlation of desk and chair compliance with student spinal curvature abnormalities. Results: The qualified rates of classroom blackboard illuminance uniformity ( 85.41 %) and the blackboard size (82.24%) were the highest in primary and secondary schools in Guizhou Province, while the average blackboard surface illumination qualified rate (20.10%) was the lowest. The average desk illumination (50.11%-58.63%), desk illumination uniformity (61.92%-72.27%) and qualified noise rate (50.04%-51.94%) increased significantly in 3 years; in addition, the compliance rate of desks and chairs decreased from 25.00% to 13.52%, and the differences were all statistically significant ( χ 2=42.48, 80.93, 46.09, 129.72, all P <0.05). Middle school classrooms outperformed primary schools in terms of per capita area, average blackboard illuminance, blackboard illuminance uniformity, average desktop illuminance, desktop illuminance uniformity, and noise compliance ( χ 2=311.55, 12.41, 20.64, 40.76, 10.25, 52.47), but had lower compliance for blackboard size and reflectance ( χ 2=537.29, 7.59) (all P <0.01). Urban schools had higher compliance than suburban schools for per capita area, average blackboard illuminance, average desktop illuminance, and desktop illuminance uniformity ( χ 2=73.71, 17.68, 29.30 , 36.03), but lower compliance for desk-chair suitability, blackboard size, and blackboard reflectance ( χ 2=4.72, 26.02, 5.43 ) (all P <0.05). The spinal curvature abnormality detection rate was 0.83%. A significant association was found between abnormality detection and desk-chair non compliance ( χ 2=223.85, P <0.01). Conclusions Classroom environment hygiene in Guizhou schools is suboptimal. Strengthening school environmental hygiene infrastructure and greater attention to its impact on student s health are essential.

Objective: To understand the epidemiological characteristics of abnormalities spinal curvature among children and adolescents in Karst landform in Guizhou Province, so as to provide a scientific basis for targeted comprehensive intervention. Methods: From September to December 2023, 194 875 children and adolescents aged 6-18 were selected from all countieldistricts of 9 cities (prefectures) in Guizhou Province by stratified random cluster sampling method according to the proportion of Karst landform area in Guizhou Province for carrying out spinal curvature abnormality screening, and a questionnaire survey was conducted on 139 449 students in the fourth grade and above of primary school. Binary Logistic regression was used for multivariate analysis. Results: The detection rate of abnormal spinal curvature among children and adolescents aged 6-18 in Guizhou Province was 1.13%. The detection rates of abnormal spinal curvature in areas with a high proportion of Karst landform, areas with a low proportion of Karst landform, intercalation areas, and nonKarst landform areas were 1.10%, 2.00%, 0.90%, and 0.60%, respectively. Among them, the detection rates of abnormal spinal curvature in female students (2.40%, 1.60%, 0.90%) in areas with a low proportion of Karst landform, intercalation areas and nonKarst landform were higher than those in male students (1.60%, 0.10%, 0.30) (χ2=12.66, 112.69, 30.22, all P<0.05). The detection rates of abnormal spinal curvature among senior high school students (2.00%, 4.30%, 1.40%, 1.30%) in different Karst landform distributions were successively higher than those among junior high school students (1.40%, 3.20%, 1.00%, 0.60%) and primary school students (0.70%, 0.80%, 0.60%, 0.30%) (χ2=306.11, 175.80, 14.24, 39.57, all P<0.05). The results of multivariate Logistic regression analysis showed that the detection rates of abnormal spinal curvature in both highproportion and lowproportion Karst landform areas were higher than those in nonKarst landform areas [OR(95%CI)=1.84(1.05-2.25), 1.60(1.23-2.09), both P<0.05]. Conclusion The detection rate of abnormal spinal curvature in children and adolescents aged 6-18 in Guizhou Province is related to the distribution of Karst landform, so it is necessary to strengthen screening and appropriate comprehensive interventions.

AIM: To explore the efficacy of bilateral lateral rectus recession in the treatment of basic intermittent exotropia. METHODS: A prospective study was conducted on 104 patients with basic intermittent strabismus admitted to our hospital from October 2022 to October 2023, patients were randomly divided into a study group of 52 cases and a control group of 52 cases using a random number ranking method. The control group received unilateral recess-resect, while the study group received bilateral lateral rectus recession, the differences in surgical success rate, postoperative strabismus, and postoperative exotropia drift were compared between two groups.RESULTS: There was no statistically significant difference between the two groups at 1 d, 1, 3, and 6 mo after surgery(all P>0.05). The strabismus in the 6 m and 33 cm eye positions at 1, 3, and 6 mo after surgery were lower than those at 1 d after surgery(all P<0.05). However, there was no statistically significant difference in the strabismus in the 6 m and 33 cm eye positions between the two groups at 1 d, 1, 3, and 6 mo after surgery(all P>0.05), and there was statistical significant difference between the two groups in exotropia drift at different postoperative time points(all P<0.05). The exotropia drift of both groups increased at 3 and 6 mo after surgery compared to 1 mo after surgery, and the exotropia drift at 6 mo after surgery was greater than that at 3 mo after surgery(all P<0.05). However, the exotropia drift of the study group at 3 and 6 mo after surgery was lower than that of the control group(all P<0.001). CONCLUSION: Bilateral lateral rectus recession for the treatment of basic-type intermittent exotropia effectively reduces the amount of postoperative exotropia drift, and it has better long-term stability.

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, 2hour 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.
