OBJECTIVE To optimize the prescription pre-review system in our hospital and evaluate its application effects. METHODS Aiming at the problems of imperfect rule base and high false positive rate in the early operation of the system， optimization measures were taken， including improving the content of the rule base， adjusting the interception level and prompt mode， refining the working model of prescription review pharmacists， and strengthening clinical communication. A retrospective cohort study was conducted， with prescription data from June to December 2023 （before optimization） as the control group and June to December 2024 （after optimization） as the observation group. Through inter group comparative analysis， the actual effect of optimizing the prescription pre-approval system was evaluated. RESULTS The prescription qualified rate increased from （82.51± 4.04）% before optimization to （90.98±1.55）% after optimization； the false positive rate decreased from （20.87±1.64）% before optimization to （7.41±2.04）% after optimization. The monthly range of prescription qualified rate narrowed from 10.24% to 4.11%， and the coefficient of variation decreased from 4.92% to 1.73%. The monthly range of false positive rate slightly increased from 4.40% to 5.34%， the coefficient of variation rose from 8.32% to 26.18%. CONCLUSIONS Through multi-dimensional optimizations of the prescription pre-review system in our hospital， its prescription review efficiency has been significantly enhanced， the quality of prescriptions has steadily improved， and the accuracy of reviews has notably improved.

ObjectiveTo analyze the prevalence and influencing factors of overweight and obesity among primary school students in a community of Fengxian District, Shanghai, and to provide references for formulating prevention and control strategies against overweight and obesity. MethodsData on height and weight of all primary school students in a community in Fengxian District, Shanghai, in 2023 were obtained by physical examination, and 1 759 primary school students were included according to the entry criteria. Overweight and obesity were determined using body mass index (BMI). Additionally, a questionnaire survey was performed to 1 045 students to collect their demographic characteristics, dietary behaviors, dietary habits, sleep and physical activity information. Chi-square test and logistic regression analysis were used to analyze the influencing factors of overweight and obesity. ResultsIn 2023, among the 1 759 primary school students in the community in Fengxian District, 923 (52.47%) were male and 836 (47.53%) were female, with an overweight/obesity detection rate of 28.08%. The detection rate of overweight and obesity was 33.37% in males and 22.25% in females, which was significantly higher in males than that in females (χ²=26.845, P<0.001). Students aged 10‒12 years had a higher overweight/obesity detection rate (32.55%) than those aged 6‒<10 years (26.53%), and the difference was statistically significant (χ²=10.925, P<0.001). Logistic regression analysis revealed that being female, with young age, parental education level of bachelor’s degree and above, a high global dietary recommendation healthy (GDR-healthy) score, preference for vegetables and sweeter home-cooked meals, and a slow eating speed were negatively correlated with overweight/obesity. Whereas, parental overweight and obesity, binge eating, and a faster eating pace than same-age, same-gender peers may be positively correlated with overweight/obesity. ConclusionThe detection rate of overweight and obesity among primary school students in the community in Fengxian District of Shanghai is higher than the national level. Gender, age, parental BMI, parental education level, dietary behaviors and habits are the main influencing factors of overweight/obesity among primary school students.

Brain-computer interface （BCI） has replaced the body as an important “channel” connecting the brain and the external world. First， “brain-computer interaction activities” differ from general human activities. They are activities jointly implemented by humans with a high-level agency and BCI with a low-level agency. Even if “brain-computer interaction activities” do not meet the requirements of the classical philosophy of action， they may still become “generalized artificial actions.” Second， BCI has altered the coherence of human activity based on “brain-body interaction，” which leads to human users holding different levels of sense of agency， and results in the situation of brain-computer interaction being divided into “online state” and “offline state.” Third， humans in an “online state” are aware of subsequent activities and moral harm， and they are the subject of accountability. Humans in an “offline state” may not necessarily be aware of subsequent activities and are not the main subject of accountability. Therefore， the definition of the attributes of brain-computer interaction activities and the analysis of the sense of agency provide a new entry point for solving the problem of “responsibility gaps” and ethical analysis of brain-computer interaction.

ObjectiveTo observe the clinical efficacy of modified Zuojinwan granules in treating reflux esophagitis （RE） and functional dyspepsia （FD） with the same syndrome with disharmony between liver and stomach）. MethodA randomized double-blind placebo-controlled clinical trial was conducted to enroll 144 patients with disharmony between liver and stomach， including 72 patients with RE and 72 patients with FD. These patients were then randomly divided into observation and control groups， with 36 patients in each group. The observation group was given modified Zuojinwan granules orally， and the control group was given placebo granules orally. They both were treated with two packs each time， twice a day， for four weeks. The traditional Chinese medicine （TCM） syndrome scores， cerebrointestinal peptides ［calcitonin gene-associated titanium （CGRP）， vasoactive intestinal peptide （VIP）， 5-hydroxytryptamine （5-HT）， and substance P （SP）］， inflammatory factors ［tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6）］， common gastrointestinal related hormones ［gastrin （GAS） and motilin （MTL）］， and other indicators in the two groups were compared before and after treatment， and the curative effect of TCM syndromes and the occurrence of adverse reactions were determined. At the same time， the changes in the above indicators and the curative effect of TCM syndromes in the two groups of patients with the same disease were analyzed. ResultAfter treatment， CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in the observation group and control group were significantly improved （P<0.05）. After treatment， the improvement of CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in the observation group was better than that in the control group （P<0.05）. After treatment， CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in both groups of RE patients and FD patients were significantly improved （P<0.05）. After treatment， the improvement of CGRP， VIP， 5-HT， SP， TNF-α， IL-6， GAS， MTL， and TCM syndrome scores in RE patients and FD patients in the observation group were better than that in the control group （P<0.05）. In the observation group and the control group， the incidence of nausea， vomiting， fatigue， dry mouth， and other adverse reactions was lower， and there was no statistical significance. ConclusionModified Zuojinwan granules can effectively improve the TCM syndromes of disharmony between liver and stomach of RE and FD， brain and intestinal peptide， gastrointestinal hormone， and inflammatory factors and provide evidence for the clinical application of TCM theory of "treating different diseases with the same method".

AIM: To investigate the relationship between vascular smooth muscle cell (VSMC) injury, organelle stress response and autophagic cell death (autophagy) and ferroptosis induced by the chemical hypoxia inducer cobalt chloride (CoCl2) through the bioinformatics analysis and in vitro cell experimentation. METHODS: The dataset GSE119226 of VSMC treated with cobalt chloride was acquired from the gene expression database (GEO). The R language was used to investigate the relationship between CoCl2 treatment and organelle stress response (Golgi stress, endoplasmic reticulum stress) and two forms of cell death (ferroptosis and autophagic cell death). With primary cultured rat VSMC (rVSMC) and CoCl2-induced anoxia model, the changes in cell viability were detected by CCK-8 method, and reactive oxygen species (ROS) levels were measured using DCFH-DA method. The expression levels of HIF-1α (a key molecule in hypoxia), Golgi stress markers GM130 and p115, endoplasmic reticulum stress markers GRP78 and CHOP, autophagy markers LC3-II / LC3-I and Beclin1, and ferroptosis markers GPx4 and xCT were detected by Western blot. The effect of inducing or inhibiting organelle stress and cell death on the CoCl2-induced cell damage was also observed. RESULTS: Differentially expressed genes analysis of GSE119226 dataset showed that CoCl2 treatment of VSMCs had significant effects on organelle function and stress response, autophagy and ferroptosis-related genes, in which endoplasmic reticulum stress, protein processing in endoplasmic reticulum, regulation of Golgi to plasma membrane protein transport, autophagy / autophagic cell death, and ferroptosis pathways were remarkably enriched. The results of in vitro experiment showed that compared with normal rVSMC, cell viability was significantly decreased after CoCl2 treatment, as well as HIF-1α protein expression and ROS levels in rVSMCs were increased. In rVSMC treated with Co-Cl2, the expression levels of Golgi structural proteins GM130 and p115 (reflecting the occurrence of Golgi stress) were decreased, while the markers GRP78 and CHOP (reflecting the occurrence of endoplasmic reticulum stress) were increased. At the same time, CoCl2 treatment also reduced the expression of autophagy markers LC3-II/LC3-I and Beclin1 (indicating the decrease levels of autophagy), while the expression of ferroptosis markers GPx4 and xCT were decreased (indicating the occurrence of ferroptosis). Compared with CoCl2 treatment group, induced Golgi stress, endoplasmic reticulum stress, or ferroptosis could further reduce cell viability, while inhibition of these processes could improve cell viability. On the other hand, increasing the level of autophagy can improve the cell viability. CONCLUSION: Hypoxia induced by cobalt chloride can lead to VSMC injury. Golgi stress, endoplasmic reticulum stress, ferroptosis, and the reduction of autophagy level play an important role in it. Inhibition of organelle stress response and ferroptosis, or increase of autophagy level can improve VSMC injury caused by cobalt chloride.

AIM: To investigate the effect of scleral-fixated capsular tension ring(SFCTR)combined with phacoemulsification and intraocular lens(IOL)implantation in the treatment of traumatic lens subluxation.METHODS: A total of 14 patients(14 eyes)who underwent SFCTR combined with phacoemulsification and IOL implantation for traumatic lens subluxation from December 2018 to February 2023 were selected. Visual acuity, intraocular pressure, anterior segment photography, and ultrasound biomicroscopy(UBM)were examined during postoperative follow-up. The location of IOL and postoperative complications were recorded.RESULTS: SFCTRs and IOLs were successfully implanted in all patients. The mean postoperative follow-up was 1.92±1.36 a. At the last follow-up, the uncorrected distance visual acuity(UDVA; 0.20±0.18 LogMAR)and corrected distance visual acuity(CDVA; 0.16±0.17 LogMAR)were significantly improved compared with the UDVA(1.13±0.56 LogMAR)preoperatively(P<0.01). The intraocular pressure(17.64±3.67 mmHg)was lower than that before the operation(22.00±9.92 mmHg; P<0.05). During the follow-up, the slit-lamp examination showed that the IOL was in the middle of the pouch. UBM examination showed that the CTR and IOL were located in the pouch, and the distance between the equatorial part of the pouch and the ciliary process was equal in all directions.CONCLUSION: The SFCTR combined with phacoemulsification and IOL implantation is an efficient and minimally invasive method in the treatment of traumatic lens subluxation.

Objective:To analyze the iodine nutrition status of children aged 8 to 10 years in Zhejiang Province from 2016 to 2021.Methods:A multi-stage stratified sampling method was used to select non-residential children aged 8 to 10 years from 90 counties in Zhejiang Province. A total of 114 103 children were included in the study from 2016 to 2021. Direct titration method and arsenic-cerium catalytic spectrophotometry were used to detect salt iodine content and urinary iodine level, respectively, to evaluate the iodine nutritional status of children. Ultrasound was used to detect thyroid volume and analyze the current prevalence of goiter in school-age children.Results:The age of 114 103 children was (9.04 ± 0.81) years old, with 50.0% of (57 083) boys. The median of iodine content M ( Q1, Q3) in children's household salt was 23.00 (19.80, 25.20) mg/kg, including 17 242 non-iodized salt, 6 173 unqualified iodized salt, and 90 688 qualified iodized salt. The coverage rate of iodized salt was 84.89%, and the coverage rate of qualified iodized salt was 79.48%. The proportion of non-iodized salt increased from 11.85% in 2016 to 16.04% in 2021 ( χ 2trend=111.427, P<0.001). The median of urinary iodine concentration M ( Q1, Q3) in children was 182.50 (121.00, 261.00) μg/L, among which the proportions of iodine deficiency, iodine suitability, iodine over suitability, and iodine excess were 17.25% (19 686 cases), 39.21% (44 745 cases), 26.85% (30 638 cases), and 16.68% (19 034 cases), respectively. The median of urinary iodine concentration in children in inland areas [ M ( Q1, Q3): 190.90 (128.80, 269.00) μg/L] was significantly higher than that in children in coastal areas [ M ( Q1, Q3): 173.00 (113.00, 250.30) μg/L] ( P<0.001). From 2016 to 2021, a total of 39 134 ultrasound examinations were conducted, and 1 229 cases of thyroid enlargement were detected. The goiter rate was 3.14% (95% CI: 2.97%-3.32%). The incidence of goiter in children in coastal areas [3.45% (95% CI: 3.19%-3.72%), 641/18 604] was higher than that in children in inland areas [2.86% (95% CI: 2.64%-3.10%), 588/20 530] ( P=0.001). Conclusion:From 2016 to 2021, the iodine nutrition level of children aged 8-10 years in Zhejiang Province is generally suitable, and the rate of goiter in children meets the limit of iodine deficiency disease elimination standards.

Objective:To analyze the clinical characteristics,diagnosis,and treatment of renal cell carcinoma in kidney transplant recipients.Methods:The clinical data of 27 kidney transplant recipients(2 female and 25 male patients)with renal cell carcinoma admitted to Tianjin First Center Hospital between March 2011 and March 2023 were retrospectively analyzed.Twenty-four of the 27 patients underwent radic-al nephrectomy,including one who underwent bilateral surgery and one who underwent nephroureterectomy.Three patients were conser-vatively treated.The surgical approaches included open,laparoscopic,and robot-assisted laparoscopic procedures,and analyses were per-formed on the diagnosis and treatment process,pathological features,and surgical prognoses of patients.Results:The surgical duration was 148 min(range,100-210 min),and the postoperative hospital stay was 7 d(range,4-10 d).Twenty-four cases of renal cell carcinoma were detected in native kidneys,with an average diameter of(4.03±2.49)cm,including 6 cases of papillary renal cell carcinomas,1 case of chro-mophobe cell carcinoma,and 17 cases of clear cell carcinomas.One of the conservatively treated patients with graft clear renal cell car-cinoma was pathologically confirmed via biopsy puncture.The clinical stages of the 27 patients were divided based on the extent of the tu-mor(T),extent of spread to the lymph nodes(N),and presence of metastasis(M),referred to as the TNM staging criteria as follows:T1aN0M0 in 18 cases,T1bN0M0 in 4 cases,T2aN0M0 in 2 cases,and T4N1M1 in 3 cases.The average age at the first tumor diagnosis after transplantation was(51.21±7.60)years.Median dialysis time before transplantation was 19 months(range,1.2-72 months).The median time from tumor diagnosis to transplantation surgery was 95 months(range,12-180 months).The median follow-up time of the 27 patients was 47 months(range,3-147 months),and two patients died after 129 and 95 months of follow-up because of pneumonia and sepsis,re-spectively.Conclusions:Early diagnosis of renal cancer after renal transplantation is difficult because of multiple cystic changes and necrotic tendencies.In addition,it is especially important to have a standardized follow-up plan and determine the timing of prophylactic surgery.

Objective:To assess the application value of low-dose contrast agent combined with bolus tracking technique in radiotherapy localization for nasopharyngeal carcinoma (NPC).Methods:One hundred patients with NPC for radiotherapy localization were enrolled prospectively and randomly divided into observation ( n = 50) and control ( n = 50) group using random number table. All patients in the control group underwent routine computerized tomography (CT) for radiotherapy localization with an intravenous bolus of 80 ml iodinated contrast media. Images were obtained at a fixed delay of 50 s from the beginning of contrast injection. Patients in the observation group underwent CT scan using a bolus tracking technique with an intravenous bolus of 50-60 ml iodinated contrast media. By observing the time-CT value monitoring curve, the scanning was manually triggered when the peak fell. The score of image quality, enhanced CT value, iodine contrast dose, and dose calculation variance of planning target volume were compared between the two different dose groups. The differences of dose were compared using independent sample t-tests and the differences in graph scores were compared using Wilcoxon rank sum tests. Results:The dosage of iodine contrast agent in the observation group was 28.75% less than that in the control group, and the difference achieved statistical significance ( t=-42.11, P<0.001). The enhanced CT value of carotid artery and jugular vein in the control group increased 32.58% and 21.02% compared with patients in the observation group, respectively ( t=-8.11 and -4.82, P<0.001 for both). No statistically significant differences in the enhanced CT value were found for the gross tumor volume (GTV) of nasopharynx or sternocleidomastoid between the two groups ( P>0.05). The images in both groups can met the requirements of target volume delineation, and the difference of subjective score was not statistically significant ( Z=-1.36, P=0.175). There were no significant differences in the signal-to-noise ratio (SNR) or contrast-to-noise ratio (CNR) of nasopharynx between the two groups ( P>0.05). The results of subjective score and GTV target area showed high consistency between the two doctors with a κ value of 0.77. The differences in dose calculation variance of planning target volume between the two different dose groups was also not statistically significant ( P>0.05). Conclusions:In the radiotherapy localization for nasopharyngeal carcinoma, the application of low-dose contrast agent combined with bolus tracking technique could obtain good images for target delineation and effectively reduce the intake of iodine contrast agent and the risk of adverse reactions. Based on these results, low-dose contrast agent combined with bolus tracking technique has wide range of application.

This paper presents two cases of renal allograft parapelvic cysts treated with ureteroscopy involving internal incision and drainage using a holmium laser. The procedure also involved cyst puncture and injection of methylthioninium chloride, with ultrasound monitoring to determine the incision location based on the 'flame sign.' The surgeries were uneventful, and follow-up ultrasounds conducted 2 to 3 months later revealed a reduction in cyst size. This technique introduces a novel approach for treating parapelvic cysts in renal allografts.
