OBJECTIVE To innovatively apply the pre-intelligent precision dosing and verification system （hereinafter referred to as “the system”）， and to provide a reference for the high-level “intelligent” transformation of inpatient pharmacy. METHODS The limitations of the triple-serial dispensing mode， which comprised the automatic medicine packaging machine （ATC）， intelligent tablet dispensing table （ITDT） and medication detection machine （MDM）， were analyzed. The application of the system and the adoption of the barcode scanning verification method optimized the pre-dosing management， whole-tablet drug dispensing process and ATC temporary dosing management. The comparative analysis was conducted to assess dosing time， labor cost and packaging error of the eight-month period， before and after the system application. RESULTS The triple-serial dispensing mode had a weak ability to avoid error risks in the manual dosing stage， and also had errors in the verification stage. Through the innovative application system， the pre-dosing management had been upgraded， the whole-tablet drug dispensing process had been optimized， and the ATC temporary dosing management had been improved. The average time required for each drug for pre-dosing， whole-tablet drug dispensing and ATC temporary dosing was significantly shortened after the application of the system， compared with before the application of the system （P＜0.001）. The number of pharmacists was reduced from two to one. The error rate of ATC decreased significantly from 0.220‰ to 0.029‰ （P＜0.001）. Specifically， the rate of pharmacist-related errors （pre-dosing error， ITDT dosing error， and ATC temporary dosing error） decreased from 0.116‰ to 0.001‰ （P＜0.001）， and machine-related errors decreased from 0.096‰ to 0.023‰ （P＜0.001）. CONCLUSIONS This innovative integration mode greatly improves the working efficiency and quality of inpatient pharmacy. It enhances refined management of drug expiration and inventory， saves time and labor costs， improves the accuracy of drug dispensing， and ensures patient medication safety.

OBJECTIVE: To compare the therapeutic efficacy and safety of local anesthesia and spinal anesthesia for the patients with varicocele (VC) who underwent microsurgical varicocelectomy (MV). METHODS: We retrospectively analyzed the data of VC patients who underwent MV treatment at the Andrology Department of the Affiliated Ruikang Hospital of Guangxi University of Chinese Medicine from May 2020 to March 2023. Cases with complete clinical data and follow-up evaluation were selected and divided into a control group (spinal anesthesia) and an observation group (local anesthesia) according to different anesthesia methods. The surgical time (including anesthesia time), visual analogue scale (VAS) score for pain, hospital stay, treatment cost, sperm concentration, forward motile sperm rate, and normal sperm morphology rate after three months of surgery, as well as postoperative complications and recurrence rate were compared between the two groups. RESULTS: A total of 107 eligible cases were included, with 56 cases in the control group and 51 cases in the observation group. There was no significant difference in the VAS score for pain during and after four hours of surgery, as well as postoperative complications, and recurrence rate between the two groups (P> 0.05). There was an significant increase in sperm concentration, forward motile sperm rate, and normal sperm morphology rate in both of two groups after three months of surgery (P<0.05). However, there was no significant difference between the two groups three months after surgery (P>0.05). The surgical time and hospital stay were shorter than those of the control group (P<0.05). And the treatment cost in observation group was lower than that of the control group (P<0.05). CONCLUSION Both local anesthesia and lumbar anesthesia for MV treatment of VC have good efficacy and safety. However, patients treated with MV under local anesthesia for VC have obvious advantages in terms of operation time (including anesthesia time), hospital stay, and treatment cost, which is worthy of clinical promotion and application.

OBJECTIVES: Depressive and anxiety disorders are among the most common mental disorders worldwide and are associated with unhealthy lifestyle behaviors. The Life's Simple 7 (LS7) guideline proposed by the American Heart Association aims to reduce cardiovascular risk by improving behaviors such as diet and physical activity, but its impact on mental health is not yet fully clear. This study examined the association between LS7 scores and symptoms of anxiety and depression in adults undergoing routine health examinations. METHODS: Data were collected from individuals who underwent health examinations from May 2015 to December 2024 at the Health Management Center of the Third Xiangya Hospital. All participants completed the LS7 assessments, the Self-Rating Depression Scale (SDS), and the Self-Rating Anxiety Scale (SAS). Participants were categorized into 4 LS7 score groups: Low (≤7), average (8-9), good (10), and excellent (11-14). Those with SDS or SAS≥50 were classified as having mental disorder symptoms; with this group, SAS≥50 indicated anxiety, SDS≥50 indicated depression, and SDS and SAS≥50 indicated comorbid anxiety-depression. Binary logistic regression was used to assess associations between LS7 score and mental symptoms, calculating odds ratio (OR) and 95% confidence interval (CI). A restricted cubic spline (RCS) regression model was used to analyze the dose-response relationship between LS7 score (continuous variable) and the risk of mental symptoms. Nodes were set at the 5th, 35th, 65th, and 95th percentiles of the LS7 score, with the 5th percentile as the reference point. All models were adjusted for covariates such as gender, age, living alone, drinking status, education level, and sleep quality. Logistic regression framework was used to fit and calculate the adjusted OR (aOR) and 95% CI. Nonlinear relationship tests were also conducted. Subgroup analysis was performed to explore the interaction between gender, age, drinking habits, education level, and other factors and the LS7 score in influencing the risk of mental symptoms. RESULTS: A total of 5 449 participants were included; 1 363 (25.01%) had depressive symptoms, 398 (7.30%) had anxiety symptoms, and 259 (4.75%) had comorbid anxiety-depression. The prevalence of mental symptoms decreased significantly as LS7 scores increased. Univariate and multivariate Logistic regression indicated that LS7 score≥8 was protective against mental symptoms. Multivariate Logistic regression demonstrated moderate discriminative ability (AUC=0.672). Among individuals with anxiety, depression, or comorbid symptoms, LS7 score distributions showed a graded decrease from poor to excellent groups. After adjustment, an excellent LS7 score was associated with a 39% lower risk of depression (aOR=0.61, 95% CI 0.47 to 0.78, P<0.001), a 63% lower risk of anxiety (aOR=0.37, 95% CI 0.22 to 0.59, P<0.001), and a 66% lower risk of comorbid anxiety-depression (aOR=0.34, 95% CI 0.17 to 0.62, P=0.001). The AUC values of the anxiety model, depression model, and comorbid anxiety and depression model were 0.632, 0.672, and 0.619, respectively. All models demonstrated moderate discriminatory ability, which was statistically significant, but their capacity to distinguish cases from non-cases was limited. RCS analysis confirmed a linear inverse relationship between LS7 score and mental symptom risk. Not smoking and regular physical activity were the strongest protective behaviors. Subgroup analysis suggested stronger protective effects in men, younger adults (≤60), non-drinkers, and those with higher education levels, and revealed a significant interaction between alcohol use and LS7 score (P for interaction=0.021), indicating that alcohol consumption may weaken the protective effect of LS7. CONCLUSIONS Ideal healthy lifestyle behaviors, as reflected by higher LS7 scores, are associated with lower risks of anxiety and depression in adults. Promoting LS7-based lifestyle practices may serve as a practical and effective strategy for the prevention and management of anxiety and depression in both clinical and daily life settings.

BACKGROUND:Alzheimer's disease is a degenerative neurological disorder characterized primarily by cognitive impairment.Acupuncture is a kind of traditional Chinese medicine therapy for treating Alzheimer's disease,but its mechanism is not yet clear. OBJECTIVE:To observe the effects of electroacupuncture with"Zhi San Zhen"on the Notch signaling pathway,β-amyloid protein(Aβ)and synaptic plasticity in 5xFAD mice. METHODS:Sixteen male,6-month-old 5xFAD mice,SPF-grade,were randomly divided into the electroacupuncture with"Zhi San Zhen"group(electroacupuncture group)and the model group,with eight mice in each group.Eight SPF-grade,male,6-month-old C57BL/6 mice were used as the wild control(wild)group.The electroacupuncture group received electroacupuncture with"Zhi San Zhen"intervention,5 times a week for 4 consecutive weeks.The model group and the wild group did not receive electroacupuncture intervention.The Morris water maze was used to preliminarily assess their learning and memory abilities.Thioflavin S staining was performed to detect Aβ plaque deposition.Western blot and real-time quantitative polymerase chain reaction(RT-qPCR)were used to measure the expression levels of transmembrane receptor protein Notch-1,Notch 1 intracellular domain(NICD),hairy and enhancer of split 1(Hes 1),hairy and enhancer of split 5(Hes 5),synaptophysin(SYN),postsynaptic density protein-95(PSD-95),and Aβ. RESULTS AND CONCLUSION:Compared with the model group,the wild group and the electroacupuncture group showed shortened escape latency,increased platform crossing times,and longer target quadrant dwell time(P<0.05).Compared with the wild group,the model group had significantly increased deposition of Aβ plaques,while electroacupuncture with"Zhi San Zhen"inhibited the deposition of Aβ plaques in the hippocampus of 5xFAD mice(P<0.05).Compared with the wild group,the model group had decreased mRNA levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue of mice,and increased mRNA levels of Aβ(P<0.05).Electroacupuncture with"Zhi San Zhen"increased the mRNA levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue,and decreased the mRNA level of Aβ(P<0.05).Compared with the Wild group,the model group had decreased protein expression levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue of mice,and increased protein expression levels of Aβ(P<0.05).Electroacupuncture with"Zhi San Zhen"upregulated the protein expression levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5,and inhibited the protein expression of Aβ(P<0.05).To conclude,electroacupuncture with"Zhi San Zhen"can improve the learning and memory abilities of 5xFAD mice,possibly by inhibiting the deposition of Aβ protein and activating the Notch signaling pathway in the hippocampus to enhance synaptic plasticity.

Objective To understand the current situation and influencing factors of kindergarten teach-ers'participation in training for preschool sex education in Luzhou city,and provide a basis for improving the sex education literacy of kindergarten teachers in the future.Methods A multi-stage stratified cluster sampling meth-od was adopted,and a questionnaire survey was conducted from December 2021 to January 2022 on the knowl-edge,attitude,and practice of preschool sex education among all the teachers in 24 kindergartens in Luzhou city.Results Among the 461 teachers,43.0％had participated in lectures/courses/training activities related to pre-school sex education;99.1％hoped to participate in lectures/courses/training activities related to preschool sex education;82.6％learned about child sexual knowledge through school education;75.5％expressed the hope to learn about child sexual knowledge through expert training.The results of multivariate Logistic regression showed that except private kindergartens as an inhibiting factor(OR=0.57,95％CI=0.37-0.87,P=0.008),high monthly income(OR=3.52,95％CI=1.13-9.30,P=0.011),more ways to know about sex education knowledge(OR=2.87,95％CI=1.76-4.70,P＜0.001),and social support(OR=1.58,95％CI=1.04-2.38,P=0.030)were promoting factors for teachers to participate in the training for preschool sex educa-tion.Conclusions The kindergarten teachers presented a participation rate but a high demand for the training for preschool sex education.They mainly obtain the sex education knowledge from school education.The nature of kindergarten,monthly income of teachers,social support situation,and ways of understanding sex education knowledge are the key factors influencing the teachers'participation in the training for preschool sex education.

Objective:To explore the feasibility of adjusting the thyroid stimulating hormone (TSH) cut-off values for screening congenital hypothyroidism (CH) in newborns according to the seasons, and to establish a TSH screening cut-off value that is suitable for the actual situation in Quanzhou City.Methods:A total of 355 868 newborns who underwent CH screening at the Neonatal Disease Screening Center in Quanzhou in Fujian Province from January 1, 2018 to December 31, 2021 were included in the study. Heel blood samples were collected and made dried blood spots. TSH levels in the heel blood of newborns were measured using genetic screening processor (GSP). The TSH cut-off values for CH screening were established using the percentile method and the receiver operating characteristic (ROC) curve method, and were adjusted based on seasonal factors. The screening efficiency was then compared with the current TSH cut-off value (9.00 mU/L).Results:According to the percentile method, the 99th percentile TSH levels in newborn heel blood in spring, summer, autumn, and winter were 9.47, 9.01, 9.41, and 10.43 mU/L, respectively. Using these values as cut-off values, the initial screening positive rates in spring, summer, autumn, and winter were 1.00% (848/84 652), 1.04% (913/87 524), 1.00% (951/94 875), 1.00% (889/88 817) [1.27% (1 077/84 652), 1.05% (916/87 524), 1.23% (1 171/94 875), 2.01% (1 787/88 817) according to the current TSH cut-off value]. However, except for summer, there were 7, 6, and 17 cases of missed screening in spring, autumn, and winter, respectively. The cut-off values of TSH for the four seasons obtained by the ROC curve method were 9.01, 9.02, 9.01, and 9.01 mU/L, respectively. The initial screening positive rates in spring, autumn, and winter were consistent with the current cut-off values, at 1.27% (1 074/84 652), 1.23% (1 167/94 875), 2.01% (1 781/88 817), respectively, while in summer, it was 0.99% (866/87 524) [1.05% (916/87 524) according to the current TSH cut-off value], and the positive detection rates in all four seasons were 100.00%.Conclusions:It is not advisable to adjust the TSH cut-off value for CH screening according to seasons in Quanzhou City. Using the current TSH cut-off value of 9.00 mU/L for CH screening in Quanzhou City can effectively ensure the quality of screening.

Objective:To analyze the status of respiratory pathogen detection and the clinical features in children with Mycoplasma pneumoniae pneumonia (MPP). Methods:A prospective, multicenter study was conducted to collect clinical data, including medical history, laboratory examinations and multiplex PCR tests of children diagnosed with MPP from 4 hospitals in China between November 15 th and December 20 th, 2023. The multiplex PCR results and clinical characteristics of MPP children in different regions were analyzed. The children were divided into severe and mild groups according to the severity of the disease. Patients in the severe group were further divided into Mycoplasma pneumoniae (MP) alone and Multi-pathogen co-detection groups based on whether other pathogens were detected besides MP, to analyze the influence of respiratory pathogen co-detection rate on the severity of the disease. Mann-Whitney rank sum test and Chi-square test were used to compare data between independent groups. Results:A total of 298 children, 136 males and 162 females, were enrolled in this study, including 204 children in the severe group with an onset age of 7.0 (6.0, 8.0) years, and 94 children in the mild group with an onset age of 6.5 (4.0, 7.8) years. The level of C-reactive protein, D-dimer, lactic dehydrogenase (LDH) were significantly higher (10.0 (5.0, 18.0) vs. 5.0 (5.0, 7.5) mg/L, 0.6 (0.4, 1.1) vs. 0.5 (0.3, 0.6) mg/L, 337 (286, 431) vs. 314 (271, 393) U/L, Z=2.02, 2.50, 3.05, all P<0.05), and the length of hospitalization was significantly longer in the severe group compared with those in mild group (6.0 (6.0, 7.0) vs. 5.0 (4.0, 6.0) d, Z=4.37, P<0.05). The time from onset to admission in severe MPP children was significantly shorter than that in mild MPP children (6.0 (5.0, 9.5) vs. 9.0 (7.0, 13.0) d, Z=2.23, P=0.026). All patients completed the multiplex PCR test, with 142 cases (47.7%) MPP children detected with 21 pathogens including adenovirus 25 cases (8.4%), human coronavirus 23 cases (7.7%), rhinovirus 21 cases (7.0%), Streptococcus pneumoniae 21 cases (7.0%), influenza A virus 18 cases (6.0%). The pathogens with the highest detection rates in Tianjin, Shanghai, Wenzhou and Chengdu were Staphylococcus aureus at 10.7% (8/75), adenovirus at 13.0% (10/77), adenovirus at 15.3% (9/59), and both rhinovirus and Haemophilus influenzae at 11.5% (10/87) each. The multi-pathogen co-detection rate in severe MPP children was significantly higher than that in mild MPP group (52.9% (108/204) vs. 36.2% (34/94), χ2=10.62, P=0.005). Among severe MPP children, there are 89 cases in the multi-pathogen co-detection group and 73 cases in the simple MPP group. The levels of LDH, D-dimer and neutrophil counts in the multi-pathogen co-detection group were significantly higher than those in the simple MPP group (348 (284, 422) vs. 307 (270, 358) U/L, 0.8 (0.5, 1.5) vs. 0.6 (0.4, 1.0) mg/L, 4.99 (3.66, 6.89)×10 9vs. 4.06 (2.91, 5.65)×10 9/L, Z=5.17, 4.99, 6.11, all P<0.05). Conclusions:The co-detection rate of respiratory pathogens, LDH and D-dimer in children with severe MPP were higher than those with mild MPP. Among severe MPP children the stress response of children in co-detection group was more serious than that of children with simple MPP.

Objective To investigate the application effect of external treatment method of Xingqi Huoxue Zhitong Paste in the treatment of phlebitis. Methods Using mannitol as an inflammatory agent, a phlebitis model was established by infusion into the ear marginal vein of rabbits. Successfully modeled rabbits were randomly divided into four subgroups for intervention, while the blank control group was routinely raised without any intervention. After the intervention, the improvement effect of Xingqi Huoxue Zhitong Paste on mannitol-induced transfusion-induced phlebitis in rabbits was explored by observing the manifestations of phlebitis, serum interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and vascular endothelial growth factor A (VEGF-A) levels. Results The success rate was up to 90.0%. On the first day of treatment, there were 8 ineffective cases and 1 effective case in the saline group; 6 ineffective cases and 3 effective cases in the hirudoid group; 7 ineffective cases and 2 effective cases in the magnesium sulfate group; 7 ineffective cases and 2 effective cases in the Xingqi Huoxue Zhitong Paste group. There was no significant difference in the curative effect among the four groups (P=0.431). On the fourth day of treatment, there were 5 ineffective cases, 2 effective cases, and 2 markedly effective cases in the saline group; 1 effective case, 5 markedly effective cases, and 3 cured cases in the hirudoid group; 2 effective cases, 5 markedly effective cases, and 2 cured cases in the magnesium sulfate group; 2 effective cases, 4 markedly effective cases, and 3 cured cases in the Xingqi Huoxue Zhitong Paste group. On the fourth day of treatment, compared with the saline group, the curative effects of the hirudoid group (P=0.001), the magnesium sulfate group (P=0.020), and the Xingqi Huoxue Zhitong Paste group (P=0.003) were statistically significant. There was no significant difference in curative effect in the magnesium sulfate group and the Xingqi Huoxue Zhitong Paste group when compared with the hirudoid group (P>0.05); there was no significant difference in curative effect in the Hirudoid group and the Xingqi Huoxue Zhitong Paste group when compared with the magnesium sulfate group (P>0.05); there was no significant difference in curative effect in the hirudoid group and the magnesium sulfate group when compared with the Xingqi Huoxue Zhitong Paste group (P>0.05). The effective rate of the saline group was 11.1%, and the cure rate was 0%. The effective rate of the hirudoid group was 100.0%, and the cure rate was 33.3%. The effective rate of the magnesium sulfate group was 77.7%, and the cure rate was 44.4%. The effective rate of the Xingqi Huoxue Zhitong Paste group was 66.7%, and the cure rate was 22.2%. The drug effectiveness of the Xingqi Huoxue Zhitong Paste group, the hirudoid group, and the magnesium sulfate group was higher than that of the saline group (P < 0.05). After the intervention, the levels of serum inflammatory factors IL-6, TNF-α, and VEGF-A in the four model subgroups were statistically significant compared with the blank control group (P < 0.05). The levels of serum inflammatory factors IL-6, TNF-α, and VEGF-A in the saline group showed significant difference from those in the hirudoid group, the magnesium sulfate group, and the Xingqi Huoxue Zhitong Paste group (P < 0.05). Compared with the hirudoid group, the differences in serum inflammatory factors IL-6, TNF-α, and VEGF-A contents in the magnesium sulfate group and the Xingqi Huoxue Zhitong Paste group were statistically significant (P < 0.05). The inflammatory factor levels in the blank control group were the lowest, while those in the normal saline group were the highest. Conclusion Xingqi Huoxue Zhitong Paste group has an improving effect on mannitol-induced infusion phlebitis in rabbits, but its efficacy is inferior to that of the commonly used hirudoid ointment. Therefore, appropriate adjustments and improvements can be made to the drug formula to enhance its effectiveness.

Objective To identify the retention time of semen(stains)inside and outside the cadaver using Fourier Transform Infrared(FTIR)spectroscopy and chemometrics.Methods A simulated environment inside the porcine vagina was used to retain fresh semen for 0～168 hours inside and outside the body.Infrared spectroscopy data were collected,and chemometric methods including Principal Components Analysis(PCA)and Partial Least Squares(PLS)regression models were established.Results The infrared spectrum peak positions of semen(stains)inside and outside the body did not show significant changes over time.The PCA results showed good clustering relationships,and the predicted deviation value in the PLS regression model was 15.786 3 hours,with an R2 value of 0.922 4.The characteristic wavenumbers selected by the CARS algorithm were in the wavelength ranges of 1 000～1 180 cm-1,1 430～1 480 cm-1,and 1 700～1 760 cm-1.Conclusion Fourier Transform Infrared spectroscopy has the potential to identify the retention time of semen(stains)inside and outside the body,and there are differences in the degradation trends of semen(stains)inside and outside the body.
