OBJECTIVE: An intelligent moxibustion instrument based on electromyography was designed to evaluate the real-time therapeutic effect of moxibustion. METHODS: Taking Shenshu (BL23) as the subject, surface electromyography (sEMG) at the center and equidistant points of Shenshu (BL23) were collected. The characteristic parameters, integrated electromyography (iEMG) and root mean square (RMS) were calculated before and after moxibustion. After analyzing the effect of moxibustion, a function algorithm for the end-of-moxibustion was obtained. Using this algorithm and combined with STM32 technology, the control system of moxibustion instrument and the upper computer software were designed to achieve the precise control during moxibustion delivery. Finally, the function, stability and safety of the moxibustion instrument were verified through clinical trials to ensure its effectiveness in practical application. RESULTS: During one cycle of moxibustion at the center of Shenshu (BL23), the iEMG of sEMG decreased over time, meaning the decrease in muscle fatigue degree, and after one cycle of moxibustion, it elevated over time, showing the increase in muscle fatigue degree. RMS increased by 1.90% before and after moxibustion at the equidistant points of Shenshu (BL23), and the system indicated the end of moxibustion when RMS increased by 0.15%, and decreased by 0.13% at the center of Shenshu (BL23). The intelligent moxibustion instrument designed based on this algorithm can realize the function of mild moxibustion, and the effect of moxibustion can be evaluated by the real-time monitoring of RMS changes through the upper computer. During the operation of moxibustion instrument, moxa stick was fixed stably, remained a safe distance of 3 cm to 4 cm away from the skin surface. When the length of moxa stick was less than 5 cm left after ignited and the skin temperature exceeded the preset safety threshold of 48 ℃, the system was alarmed automatically. CONCLUSION The intelligent moxibustion instrument designed in the research can effectively evaluate the effect of moxibustion, and ensure the safety and stability during moxibustion delivery.

OBJECTIVE To summarize the current situation of pharmaceutical clinic service in our hospital over the past five years， and explore sustainable development strategies for service models of pharmaceutical clinics. METHODS A retrospective analysis was conducted on the consultation records of patients who registered and established files at the pharmaceutical clinic in our hospital from January 2019 to December 2023. Statistical analysis was performed on patients’ general information， medication- related problems， and types of pharmaceutical services provided by pharmacists. RESULTS A total of 963 consultation records were included， among which females aged 20-39 years accounted for the highest proportion （66.04%）； obstetrics and gynecology- related consultations accounted for the largest number of cases. Additionally， 80 patients attended follow-up visits at our hospital’s pharmaceutical clinic. A total of 1 029 medication-related issues were resolved， including 538 cases of drug consultations （52.28%）， 453 medication recommendations （44.02%）， 22 medication restructuring（2.14%）， and 16 medication education （1.55%）； the most common types of medication-related problems identified were adverse drug events（70.07%）. CONCLUSIONS Although the pharmaceutical clinic has achieved recognition from clinicians and patients， challenges such as low awareness among healthcare providers and the public persist. Future efforts should focus on strengthening information technology construction， enhancing pharmacist training， and establishing various forms of outpatient pharmaceutical service models.

Objective To explore the clinical characteristics and risk factors of upper urinary tract stones complicated with non-alcoholic fatty liver disease(NAFLD),so as to provide reference for the prevention of this disease.Methods The clinical data of 158 NAFLD patients undergoing surgical treatment in our hospital during Jan.2022 and Jul.2023 were retrospectively analyzed.According to whether the patients were complicated with NAFLD,they were divided into the NAFLD group(n=56)and non-NAFLD group(n=102).The general data,laboratory indexes and 24-h urinary metabolic indexes were compared between the two groups,and the risk factors were analyzed with univariate and multivariate logistic regression analyses.Results Compared with the non NAFLD group,the NAFLD group had higher BMI[(28.17±4.17)vs.(24.11±3.72),P＜0.001],blood uric acid[(354.13±111.01)μmol/L vs.(294.41±93.72)μmol/L,P＜0.001],and 24-h urinary oxalate level[(37.74±15.00)mmol vs.(27.73±15.27)mmol,P＜0.001].Multivariate logistic analysis showed that BMI(OR=1.311,P＜0.001),24-h urinary oxalate(OR=1.046,P=0.004),and 24-h urinary magnesium(OR=0.599,P=0.002)were the independent factors for NAFLD with upper urinary tract stones.Conclusion NAFLD complicated with upper urinary tract stones is significantly associated with high BMI,high 24-h urinary oxalate,and low 24-h urinary magnesium.

Objective To investigate relative translations of the glenohumeral joint during abduction, scaption and forward flexion in normal Chinese, so as to provide references for diagnosis, treatment and follow-up of glenohumeral joint instability and subacromial impingement syndrome.Methods The biplanar fluoroscopy system combined with model-image registration technique were used to measure the humeral translation relative to the scapular in 13 healthy volunteers during abduction, scaption and forward flexion.Results The anterior-inferior glenohumeral translation during abduction, scaption and forward flexion was (4.0±1.3), (4.1±1.5),(4.8±1.9) mm, respectively. The superior-inferior glenohumeral translation was (3.0±1.0), (3.1±1.1), (3.3±1.5) mm, respectively. During the whole motion, there was a significant difference in superior-inferior translation at different arm elevation angles, while other significant differences were not found.Conclusions For normal Chinese, the humeral head was positioned posteriorly and superiorly on the glenoid. During forward flexion, the anterior-inferior and superior-inferior glenohumeral translation was the maxium. Therefore, in the process of clinical diagnosis, treatment and follow-up, patients performing the forward flexion may obtain a better evaluation effect.

Objective:To investigate the expression level of circular RNA circ_0020123 in ovarian cancer (OC) , and then to evaluate the diagnostic value of circ_0020123 level in ovarian cancer.Methods:Fifty-five ovarian cancer patients who were diagnosed and treated in Hangzhou Linping District Maternal and Child Health Hospital from Oct. 2016 to Mar. 2017 were selected, and serum was collected for high-throughput gene expression sequencing analysis. The circ_0020123 level in serum of ovarian cancer patients and healthy controls was determined by real-time quantitative PCR, and the diagnostic efficacy of circ_0020123 level on ovarian cancer was evaluated by drawing receiver operating characteristic curve (ROC) . The correlation between the expression of circ_0020123 and the clinical characteristics of ovarian cancer patients was investigated by t-test. The survival curve was drawn to analyze the relationship between the serum circ_0020123 level and the prognosis and survival of ovarian cancer patients. Western blot was used to detect the expression levels of autophagy-related proteins LC3-II/LC3-I and p62.Results:Compared with the serum of healthy people (1±0.25) , the expression of circ_0020123 was significantly up-regulated in the serum of ovarian cancer patients (1.24±0.23) ( t=5.23, P<0.001) . The ROC curve showed that circ_0020123 had high diagnostic performance for the detection of ovarian cancer specimens (AUC=0.7579, P<0.001) . Comprehensive analysis of t test and logistic analysis showed that the high expression of circ_0020123 was significantly correlated with FIGO stage ( t=5.46, P<0.001) and tumor size ( t=6.37, P<0.001) . The measurement of survival data showed that the 5-year overall survival of the circ_0020123 high expression group was significantly shorter than that of the circ_0020123 low expression group ( P=0.019) . Knockdown of circ_0020123 in cells down-regulated the expression of autophagy-related proteins LC3-II/LC3-I (0.45±0.05) ( t=9.31, P=0.001) , and up-regulated the expression of p62 (1.94±0.11) ( t=12.62, P<0.001) . Conclusion:The results of this study indicate that circ_0020123 is an important ovarian cancer-related circular RNA, which provides a potential diagnostic, prognostic biomarker and therapeutic target for ovarian cancer patients.

Objective To explore the influence of hook deflection angle and inclination angle on mechanical properties of the soft tissue suture passer hook. Methods Taking the end face far away from the tip of the needle (end face 1) as the study object, a mathematical model was established with the moment as dependent variable and the hook deflection angle and inclination angle as the independent variable. The moment was solved by the mathematical model with the deflection angle and inclination angle of 0°, 10°, 20° and 30°. Based on the finite element analysis method, 16 three-dimensional geometric hook models with deflection angle and inclination angle of 0°, 10°, 20° and 30° were established by SolidWorks. The stress analysis was carried out by ANSYS Workbench. Under the same puncture force, the maximum von Mises stress of each hook and the reaction moment of end face far away from the tip of the needle were calculated. Results The results from theoretical analysis and numerical simulation showed that the reaction moment of end face 1 increased with the increase of deflection angle, and increased with the decrease of inclination angle. The hook with deflection angle of 0° and inclination angle of 30° had the minimum reaction moment. The finite element analysis results showed that with the deflection angle of 0°, the maximum von Mises stress of the hook was the smallest and did not change with the inclination angle of the hook changing. Conclusions The established mathematical model can accurately explain the relationship between the moment at the end face of the hook and the deflection angle and inclination angle of the hook. This study provides the theoretical basis for designing hook geometry of the soft tissue suture passer, and improves the safety of the soft tissue suture passer in operation process.
