ObjectiveChinese patent medicines for cardiovascular and cerebrovascular diseases are diverse and complex in their efficacy. The traditional classification method based on efficacy categories has certain limitations and cannot meet the clinical needs for individualized drug selection and variety comparison. This article， based on the formulation compatibility analysis technology of "Tangye Jingfa Tu"， clarifies the composition and efficacy characteristics of common Chinese patent medicines used for cardiovascular and cerebrovascular diseases， providing support for the precise selection of these medicines. MethodsFifty-six representative Chinese patent medicines， covering all the efficacy subcategories of "stasis-resolving agents" in the National Basic Medical Insurance， Work Injury Insurance， and Maternity Insurance Drug Catalogue （2023） （more than 50% of the total）， were selected for the study. Within the knowledge system of "Tangye Jingfa Tu"， the compatibility structure of herbal flavors and the proportion structure of herbal quantities for each Chinese patent medicine were determined. The correlation between these structures and the efficacy categories was analyzed to identify the similarities and differences among the selected Chinese patent medicines. Additionally， the efficacy was reclassified and compared according to the theoretical framework of tonifying and purging methods of five Zang organs in the "Tangye Jingfa Tu". ResultsThe representative Chinese patent medicines included in the analysis were Shexiang Baoxin pills， Danshen tablets， Qili Qiangxin capsules， Breviscapine tablets， etc.， covering all the efficacy subcategories of "stasis-resolving agents". Among the 56 representative Chinese patent medicines， salty flavor was the most common （48）， followed by pungent （33）， and sweet （26）. According to the dominant herbal flavor， salty flavor was the most common （37）， followed by pungent （9）， and sour （5）. According to the dominant herbal quantity， salty flavor was the most common （27）， followed by sour （7）， and pungent （5）. Furthermore， Chinese patent medicines with different efficacy subtypes showed different flavor characteristics. For example， most Qi-invigorating and blood-activating agents contained sweet drugs for tonifying the spleen （9/10）， most Qi-moving and blood-activating agents contained pungent drugs for tonifying the liver （7/8）， and all kidney-invigorating and blood-activating agents contained bitter drugs for tonifying the kidneys （6/6）. However， the efficacy classification of individual medicines did not always align with the compatibility characteristics of their formulas， as seen with Dengyin Naotong capsules. ConclusionThe formulations of Chinese patent medicines for cardiovascular and cerebrovascular diseases predominantly feature salty， sour， and pungent flavors， which largely conform to the therapeutic principles of "nourishing the heart with salt and soothing the heart with sour" and the liver-heart， heart-spleen mother-child treatment relationship shown in the "Tangye Jingfa Tu". Using the "Tangye Jingfa Tu" framework to conduct research on the structure and efficacy characteristics of Chinese patent medicines is objective and effective.

Objective To explore the effects of exosomes loaded with ginsenoside Rh2 on the biological functions of hepatocellular carcinoma cells. Methods Both Huh7 and PLC/PRF/5 cell were equally divided into control group, exosome group (Exos group), drug group (G-Rh2 group), and exosomes-loaded-with-ginsenoside Rh2 group (Exos@G-Rh2 group). The effects of each group on the viability, clonogenic ability, migration ability, invasion ability, and apoptotic level of hepatocellular carcinoma cells were detected through CCK-8 assay, colony formation assay, cell scratch assay, Transwell assay, and flow cytometry. Results Compared with the control group, the Exos@G-Rh2 group and G-Rh2 group showed significantly decreased cell viability, clonogenic ability, and migration and invasion capabilities, along with a markedly increased cell apoptosis rate (P<0.05). These changes were more pronounced in the Exos@G-Rh2 group than in the G-Rh2 group (P<0.05). Conclusion Exos@G-Rh2 can effectively inhibit the viability and clonogenic, migration, and invasion abilities of liver cancer cells and induce cell apoptosis. This effect is stronger than that of free G-Rh2 at the same concentration.

Objective To evaluate the safety and feasibility of remote robot-assisted thoracoscopic surgery utilizing 5G technology. Methods Clinical data from five patients who underwent 5G remote robot-assisted thoracoscopic surgery at the Thoracic Surgery Center of Gansu Provincial People's Hospital from May to October 2024 were retrospectively analyzed. Results Finally, five patients were included. There were 2 males and 3 females at median age of 50 (42-63) years. All five surgeries (including 1 patient of lobectomy, 3 patients of partial lung resection and 1 patient of mediastinal lesion resection) were successfully completed without conversion to thoracotomy, complications, or mortality. The median intraoperative signal delay across the patients was 39 (37-42) ms. The median psychological load score for the surgeons was 9 (3-13). The median operation time was 100 (80-122) minutes with a median intraoperative blood loss of 100 (30-200) mL. Catheter drainage lasted a median of 4 (3-5) days, and the median drainage volumes on the first, second, and third postoperative day were 200 (100-300) mL, 150 (60-220) mL, and 80 (30-180) mL, respectively. The median postoperative hospital stay was 4 (3-7) days, and the median pain scores on the third postoperative day were 3 (1-4), 3 (0-3), and 1 (0-3), respectively. Conclusion 5G remote robot-assisted thoracoscopic surgery is safe and effective, with good surgical experience, smooth operation and small intraoperative delay.

AIM:To explore the effect of high aspherical lenticule on controlling low myopia.METHODS: Prospective study. A total of 100 patients aged 7 to 12 years old with low myopia who visited our hospital from May 1 to 31, 2022 were collected. They were divided into two groups with 50 cases in each group according to the wishes of patients. The control group was given single vision glasses after optometry, while the study group was given high aspherical lenticule. The myopia progression(absolute value), axial length(AL)growth, transition rate to moderate myopia, and AL negative growth rate over 6 mo and 1 a were compared between the two groups.RESULTS: The myopia progression and the AL growth of study group was lower than that of the control group after 6 mo and 1 a(all P<0.001).The negative growth rate of AL after 6 mo of treatment was significantly higher than that of the control group(P<0.001). The transition rate to moderate myopia between the two groups was not statistically significant(P=0.62); while the transition rate to moderate myopia in the study group was significantly lower than that in the control group after wearing lens for 1 a(P<0.001), and there was no statistically significant difference in AL negative growth rate between the two groups(P=0.12). Compare with single vision glasses, high aspherical lenticule achieved an 88.2% control rate for low myopia progression over 6mo and a 90.0% control rate of AL growth. The control rate for low myopia to moderate myopia was 66.7%; while the control rate of myopia progression growth was 75.6% after wearing lens for 1a, the control rate of AL growth was 69.2%, and the control rate of the transition rate to moderate myopia was 88.9%.CONCLUSION: For children and adolescents aged 7 to 12 with low myopia, high aspherical lenticule was more effective than single vision glasses in controlling myopia, making it one of the optimal choices for myopia control.

Objective To investigate the retrospective study of the treatment of primary immune thrombocytopenia(ITP)with Aitracopol.Methods Medical records of 90 patients with ITP who received treatment in our hospital from October 2018 to February 2022 were retrospectively analyzed and grouped according to different treatment methods,with an average n=45.Dexamethasone group was treated with dexamethasone group,and itrepopopa group was treated with dexamethasone group and itrepopopa group combined with dexamethasone group,all n=45.The immune function,therapeutic effect and adverse reactions were compared.Results At 4 weeks after treatment,the levels of interleukin(IL)-2 and interferon(INF)-γ in the Altropopar group and dexamethasone group were lower than before treatment,and the levels of IL-4 in the Altropopar group and dexamethasone group were higher than before treatment.Aitripopal group was higher than dexamethasone group(P<0.05);At 4 weeks after treatment,the proportions of platelet(PLT)≥30×109/L were 68.89%and 40.00%in the Altropopar group and dexamethasone group,and the proportions of PLT≥50×109/L were 55.55%and 20.00%,respectively.The proportions in the Altropopar group were higher than those in the dexamethasone group(P<0.05).The proportions of PLT≥50×109/L in the half time and dexamethasone groups were 66.67%and 33.33%,respectively,and the proportions of PLT≥50×109/L for at least one time were 93.33%and 44.44%,respectively.The proportions of PLT≥50×109/L at least once after 9 months of treatment were 60.00%and 26.67%,respectively,and the attripopal group was higher than dexamethasone group(P<0.05).A comparison of the adverse reaction rate between aitopopal group and dexamethasone group(P>0.05).Conclusion Aitracopal can significantly reduce the risk of bleeding in patients with ITP,improve immune function,improve therapeutic effect,and high safety.

The use of nitrification inhibitors has been suggested as a strategy to decrease cadmium(Cd)accumulation in crops.However,the most efficient nitrification inhibitor for mitigating crop Cd accumulation remains to be elucidated,and whether and how changes in soil microbial structure are involved in this process also remains unclear.To address these questions,this study applied three commercial nitrification inhibitors,namely,dicyandiamide(DCD),3,4-dimethylpyrazole phosphate(DMPP),and nitrapyrin(NP),to pakchoi.The results showed that both DCD and DMPP(but not NP)could efficiently decrease Cd concentrations in pakchoi in urea-and ammonium-fertilized soils.In addition,among the three tested nitrification inhibitors,DMPP was the most efficient in decreasing the Cd concentration in pakchoi.The nitrification inhibitors decreased pakchoi Cd concentrations by suppressing acidification-induced Cd availability and reshaping the soil microbial structure;the most effective nitrification inhibitor was DMPP.Ammonia oxidation generates the most protons during nitrification and is inhibited by nitrification inhibitors.Changes in environmental factors and predatory bacterial abundance caused by the nitrification inhibitors changed the soil microbial structure and increased the potential participants in plant Cd accumulation.In summary,our study identified DMPP as the most efficient nitrification inhibitor for mitigating crop Cd contamination and observed that the soil microbial structural changes caused by the nitrification inhibitors contributed to decreasing Cd concentration in pakchoi.

Objective To explore the clinical characteristics and treatment scheme of periprosthetic joint infection(PJI)caused by Cutibacterium avidum(C.avidum).Methods The diagnosis and treatment process of a patient with PJI caused by C.avidum was summarized,and relevant literatures in the database were retrieved for review.Results A 65-year-old female patient with body mass index(BMI)of 31.1 kg/m2 underwent left humeral head prosthesis replacement surgery following a left proximal humerus fracture.Ten months after the surgery,the pa-tient exhibited poor wound healing and oozing,along with limited movement of the left shoulder joint,and was diag-nosed infection following shoulder arthroplasty.Patient underwent debridement of the infected lesion and removal of the prosthesis.The tissue,bone cement and prosthesis were cultured for C.avidum.Four literatures were re-trieved and screened,a total of 30 patients with PJI(28 cases hip joint infection and 2 cases shoulder joint infection)caused by C.avidum were reported through literature retrieval,and 78.6％(n=22)total hip arthroplasty(THA)surgeries were performed using direct anterior approach(DAA).The positive rate of preoperative joint fluid culture was 71.4％,29 cases underwent surgical combined with sensitive antimicrobials treatment.Except for one patient who had repeated infection and underwent three surgeries,other patients had a good prognosis.Conclusion PJI caused by C.avidum is mostly seen in THA patients who are obese and undergo DAA,with a few cases reported after shoulder arthroplasty.The high sensitivity of preoperative joint fluid culture provides an important basis for the development of surgical strategies and anti-infection protocols.

Objective:To explore the influencing factors of psychological distress in middle-aged and young stroke patients to provide evidence for improving the mental health of the patients and guiding clinical psychological nursing interventions.Methods:A cross-sectional survey was conducted on 447 middle-aged and young patients with stroke hospitalized in four hospitals in Tianjin from March 2022 to January 2023.Various assessment scales were employed, including a general data questionnaire, distress thermometer, numerical rating scale, family APGAR index, perceived social support scale, general self-efficacy scale, Herth hope index, self-rating anxiety scale and self-rating depression scale.Statistical analyses were performed using encompassing descriptive statistics, Wilcoxon Mann-Whitney test, Kruskal Wallis test, Spearman correlation analysis, and structural equation modeling of SPSS 25.0 and AMOS 24.0.Results:The psychological distress score of middle-aged and young stroke patients was 1(1, 2). Age( Z=-5.497), marital status( Z=-2.755), number of children( H=25.448), co-residents( H=14.389), occupation( H=34.889), per capita monthly family income( H=19.105), hospitalized caregivers( H=23.794), stroke type( H=23.308), course of disease( H=10.649), number of chronic diseases( H=8.021), daily self-care ability( H=128.439), eating status( H=41.904), physical status( H=49.786), excretion status( H=112.736), dressing ability( H=63.036), nutritional status( H=15.514), organ injury status ( H=23.797)and edema status( Z=-4.307)affected the psychological distress of middle-aged and young stroke patients, and the differences were statistically significant (all P<0.05). Correlation analysis showed that psychological distress were positively correlated with pain(1(1, 1)), anxiety(36(27, 53)) and depression(31(27, 58)) ( r=0.390, 0.525, 0.591, all P<0.001), while were negatively with family caring degree(10(10, 10)), perceptive social support(72(67, 74)), general self-efficacy(35(29, 38)) and hope level(41(36, 45)) ( r=-0.200, -0.464, -0.647, -0.675, all P<0.01). Results of the structural equation model of the influencing factors of psychological distress in middle-aged and young stroke patients showed that a total of 5 common factors were extracted, which were named support system, daily activities, disease condition, general condition and physical burden.Disease condition and physical burden had direct positive effects on psychological distress ( β=0.385, 0.204, both P<0.05). Support system, daily activities and general situation had direct negative effects on psychological distress ( β=-0.332, -0.262, -0.258, all P<0.05). Conclusions:The influencing factors of psychological distress in middle-aged and young stroke patients are disease status, support system, daily activities, general conditions and physical burden, which can provide theoretical basis for nurses to carry out active and effective prevention and nursing intervention on psychological distress in middle-aged and young stroke patients.

Purpose To construct a benign and malignant prediction model of thyroid nodules based on ultrasound image features and clinical features,and to evaluate its diagnostic efficacy.Materials and Methods The data of 121 patients diagnosed with thyroid nodules admitted to the General Hospital of Northern Theater Command from September 2020 to March 2022 were retrospectively analyzed.Taken surgical pathology as the gold standard,there were 70 benign nodules and 51 malignant nodules.Logistic regression was used to analyze the ultrasound image characteristics and clinical data of thyroid nodules,and the characteristic indexes with statistical differences were obtained and a comprehensive prediction model was established.Results There were significant differences in the maximum diameter,morphology,calcification,capsule continuity,blood flow grade,elastography score and contrast-enhanced ultrasound characteristics between benign and malignant thyroid nodules(χ2=11.709,17.707,6.901,12.785,16.984,57.095,98.854,all P<0.05).There were significant differences in age,free thyroxine/free thyroxine ratio,and free thyroxine between the two groups(χ2/t=5.944,2.519,-2.468,all P<0.05).The sensitivity,specificity and accuracy of the clinical model,ultrasonic characteristic model and ultrasonic-clinical combined model were 55.7%,98.6%and 97.0%;72.5%,94.1%and 96.1%;and 61.9%,95.1%and 95.9%,respectively.The area under the curve of the three models were 0.619,0.991 and 0.994,respectively.The diagnostic efficiency of the ultrasonic characteristic model and the combined model was superior to the clinical model,and the difference was statistically significant(Z=-1.75,-2.25,P=0.039,0.012).The area under the curve of the combined model was greater than that of the multi-modal ultrasound model,however,the difference was not statistically significant(Z=-1.60,P=0.054).Conclusion Both the multimodal ultrasound model and the clinical model have certain diagnostic value in predicting benign and malignant thyroid nodules.The diagnostic efficiency of the multimodal ultrasound model is higher than that of the clinical model,and the combined prediction model of the two can improve the diagnostic value.
