The study focuses on the concept of multifunctional traditional Chinese medicine (TCM) formulas and aims to evaluate the efficacy of the classical formula Xiaoyao San (逍遥散). Study employs the integrated evidence chain (Eff-iEC) method to organize, integrate, and evaluate its therapeutic efficacy in treating different diseases with the same therapy, and to investigate the feasibility of using Eff-iEC to evaluate the multifunctionality of TCM formulas. The evaluation covered Xiaoyao San's therapeutic effects on depression, premenstrual syndrome, chronic hepatitis, irritable bowel syndrome, dyspepsia, and menopausal syndrome. Concurrently, the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system was used for evaluation, and authoritative medical documents were incorporated to corroborate the recognition of Xiaoyao San within the medical community. Depression and menopausal syndrome received higher ratings than other conditions in the Eff-iEC, GRADE, and Medical Community Recognition assessments. The Eff-iEC evidence grade for Xiaoyao San was rated as "High" or above for chronic hepatitis, irritable bowel syndrome, dyspepsia, and menopausal syndrome. Premenstrual syndrome received a "Moderate ⁺" rating. The GRADE evidence level was "Low-〇〇⨁⨁" for depression, premenstrual syndrome, and chronic hepatitis; "Moderate-〇⨁⨁⨁" for dyspepsia and menopausal syndrome; and "Very Low-〇〇〇⨁" for irritable bowel syndrome. Depression and menopausal syndrome had the highest inclusion frequency, appearing in all 4 categories. Premenstrual syndrome, chronic hepatitis, and dyspepsia are not recommended in Western medical guidelines, but they are included in TCM guidelines, the China National Basic Medical Insurance Drug List, and the China National Essential Drug List. Irritable bowel syndrome appears only in the China National Basic Medical Insurance Drug List and China National Essential Drug List. The evaluation results obtained using the Eff-iEC method align with Medical Community Recognition, providing an objective and comprehensive assessment of Xiaoyao San's efficacy. The findings suggest that Xiaoyao San has strong evidence for treating depression and menopausal syndrome. However, further experimental and clinical trials are needed to assess its efficacy in treating premenstrual syndrome, chronic hepatitis, irritable bowel syndrome, and dyspepsia. These results support the clinical efficacy and rational use of Xiaoyao San, expand the application scope of the Eff-iEC method, and offer valuable insights and methodological references for the comparative evaluation of multifunctional TCM formulas.

BACKGROUND:Micro-robots have the characteristics of small size,flexibility,and strong targeting,and can complete complex tasks in a single or clustered manner in a narrow environment.With the continuous optimization of materials,preparation processes,and driving approaches,they have shown increasingly important application value in the field of biomedicine. OBJECTIVE:To analyze the application of field-driven micro-robots in medical field and to look forward to their application prospect. METHODS:Using"microrobots,nanorobots,drivers,biomedical,medical"as Chinese keywords and"microrobots,micro-robots,nanorobots,micromachine,microswimmer,medical"as English keywords,WanFang Data and PubMed databases were searched,respectively.The search time range was from January 2010 to January 2024,and a small number of long-term articles were included.Through reading the titles and preliminarily screening the abstracts,the repetitive studies,low-quality journals,and irrelevant literature were excluded.After reading the entire text,66 papers were finally included for review. RESULTS AND CONCLUSION:Field-driven medical micro-robots mainly include magnetic,optical,thermal,ultrasonic,and multi-mixed factor-driven robots.Field-driven robots have been used in intestinal diagnosis,drug targeting therapy,and stem cell therapy.Medical micro-robots are currently only used in a small number of clinical applications,but most of which are still in the theoretical and experimental stages.Medical micro-robots will face many challenges in future,such as large-scale preparation,precise control of micro-robots,recycling or degradation in vivo,whether the materials used will cause adverse reactions to the human body,and the related minimally invasive medical procedures.

Objective:To explore the incidence and risk factors of severe bleeding after percutaneous renal biopsy (PRB) in patients with advanced chronic kidney disease (CKD).Methods:The study was a retrospective cohort analysis. The data were collected from patients with advanced CKD who were hospitalized in the Department of Nephrology, Nanfang Hospital, Southern Medical University and underwent PRB between January 2010 and December 2020. Severe bleeding after PRB was defined by any of the following criteria: a postoperative hemoglobin decrease of ≥20 g/L within 48 hours, a maximum diameter of perirenal hematoma ≥5 cm postoperatively, or the need for posterior pituitary hormone, blood transfusion, or renal vascular intervention post-surgery. The occurrence of severe bleeding following PRB served as the primary endpoint for this study. Logistic regression model was used to analyze the risk factors associated with severe bleeding in patients with advanced CKD undergoing PRB.Results:A total of 895 patients aged (46.1±14.1) years were encompassed in the study. Among them, 60.1%(538/895) were male, 15.9%(142/895) were afflicted with diabetes, and 57.9%(518/895) suffered from hypertension. The estimated glomerular filtration rate (eGFR) was (40.1±13.2) ml?min -1?(1.73 m 2) -1, and the 24-hour urine protein excretion was 2.5(1.1, 4.9) g. After PRB, 22.9%(205/895) of the patients encountered severe bleeding, including 30 patients (14.6%) who received postoperative somatostatin, 10 patients (4.9%) who underwent postoperative blood transfusion, 1 patient (0.5%) who underwent postoperative renal vascular intervention for hemostasis, and no fatalities occurred. Compared to the non-severe bleeding group, patients in the severe bleeding group after PRB exhibited a higher proportion of hypertension [64.4%(132/205) vs. 55.9%(386/690), χ2=4.627, P=0.031]. Additionally, preoperative serum creatinine levels and mean arterial pressure were significantly elevated [(193.9±106.6) μmol/L vs. (180.8±102.6) μmol/L, t=-2.559, P=0.011; (95.8±10.9) mmHg vs. (93.9±11.0) mmHg, t=-2.134, P=0.033]. Furthermore, platelet counts were lower in the severe bleeding group [(227.5±70.3) ×10 9/L vs. (247.5±74.8) ×10 9/L, t=-3.788, P<0.001]. No statistically significant differences were observed between the two groups regarding age, gender distribution, prevalence of diabetes mellitus, as well as preoperative serum albumin level, hemoglobin concentration, other coagulation function indicators and pathological histological type (all P>0.05). Multivariate logistic regression analysis indicated that body mass index ( OR=0.936, 95% CI 0.891–0.984, P=0.010), eGFR ( OR=0.985, 95% CI 0.971–0.999, P=0.034), serum albumin level ( OR=1.041, 95% CI 1.011–1.072, P=0.007), 24 hours urinary protein excretion ( OR=1.092, 95% CI 1.030–1.158, P=0.003), and platelet count ( OR=0.996, 95% CI 0.994–0.999, P=0.002) were independently associated with the severe bleeding following PRB in patients with advanced CKD. In the PRB cohort analyzed, the six most prevalent renal histological types were as follows: IgA nephropathy (46.3%, 414/895), membranous nephropathy (11.1%, 99/895), focal segmental glomerulosclerosis (8.5%, 76/895), diabetic nephropathy (7.6%, 68/895), sclerotic kidney disease (6.9%, 62/895), and vascular sclerosis of the kidneys (4.9%, 44/895). Conclusions:Patients with advanced CKD exhibit a heightened risk of severe bleeding following PRB, estimated at approximately 22.9%. Independent risk factors for the occurrence of severe bleeding complications in these patients include low body mass index, reduced eGFR, decreased platelet count, elevated serum albumin, and increased urinary protein level.

Objective:The distribution characteristics of intrathecal drugs and the limitation of current catheterization techniques make traditional intrathecal analgesic treatment nearly useless for refractory craniofacial pain,such as trigemina neuralgia.This technical guideline aims to promote the widespread and standardize the application of intra-prepontine cisternal drug delivery via spinal puncture and catheterization. Methods:A modified Delphi approach was used to work for this guideline.On the issues related to the intra-prepontine cisternal targeted drug delivery technique,the working group consulted 10 experts from the field with 3 rounds of email feedback and 3 rounds of conference discussion. Results:For the efficacy and safety of the intra-prepontine cisternal targeted drug delivery technique,a consensus was formed on 7 topics(with an agreement rate of more than 80%),including the principles of the technique,indications and contraindications,patient preparation,surgical specifications for intra-prepontine cisternal catheter placement,analgesic dosage coordination,analgesic management,and prevention and treatment of complications. Conclusion:Utilizing the intra-prepontine cisternal drug infusion system to manage refractory craniofacial pain could provide advantages in terms of minimally invasive,secure,and effective treatment.This application can not only alleviate the suffering of individuals experiencing the prolonged pain but also support the maintenance of quality of life and dignity in their final moments,justifiing its widespread dissemination and standardized adoption in domestic and international professional fields.

Objective: To investigate the characteristics of public health emergencies in Zhejiang Province in 2023, so as to provide the reference for public health risk management. Methods: Data of public health emergencies and related information in Zhejiang Province from January 1 to December 31, 2023 was collected through Emergency Public Reporting System of Chinese Disease Prevention and Control Information System. Attack rates, disease types, distribution of time and places, and responses were descriptively analyzed. Results: A total of 718 public health emergencies were reported in 2023 in Zhejiang Province, and all were infectious disease events. There were 27 128 reported cases and 3 deaths, with an attack rate of 3.22%. The top five infectious diseases with the highest number of reported events were influenza, norovirus infection, monkeypox, varicella and hand, foot and mouth disease, accounting for 95.54% of total reported events. There were 355 public health emergencies with less than 30 cases each, accounting for 49.44%. The reported emergencies peaked from February to March (186 events, 25.91%) and from November to December (327 events, 45.54%), and mainly occurred in schools and preschool institutions (651 events, 90.67%). The median responding time, reporting time and duration of emergencies were 6.50 (interquartile range, 10.84) h, 0.53 (interquartile range, 0.63) h and 7.24 (interquartile range, 11.71) d, respectively. Conclusion Public health emergencies in Zhejiang Province in 2023 were mainly caused by influenza and norovirus infection, with February, March, November and December being the peak reporting periods, and schools and preschool institutions being the main places where these events occurred.

【Objective】 To investigate the relationship between serum reproductive hormones and sperm parameters and outcomes of micro-testicular sperm extraction (Micro-TESE). 【Methods】 Clinical data of 1 091 patients treated in our hospital during Jan. and Dec.2021 were retrospectively analyzed. According to the sperm concentration,the patients were divided into non-obstructive azoospermia (NOA) group (group A,n=418),normal sperm concentration group (group B,n=615),mild to moderate oligospermia group (group C,n=18),severe oligospermia group (group D,n=18),and obstructive azoospermia group (group E,n=22). In group A,244 cases treated with Micro-TESE were grouped into the sperm-acquired group (Micro-TESE positive group,n=82) and non-sperm-acquired group (Micro-TESE negative group,n=162),and according to the pathological types of testicular tissue,the patients were divided into normal testicular tissue with hypospermatogenesis group (HYPO group,n=129),maturation arrest group (MA group,n=10),and support-only cell syndrome group (SCO group,n=122). Differences in semen parameters and reproductive hormone levels were compared,and relationship between reproductive hormones and sperm parameters and Micro-TESE outcomes was determined with Pearson correlation analysis. 【Results】 In the sperm concentration subgroup,the testicular volume of group A was lower than that of group B and group E (P<0.05); the levels of follicle stimulating hormone (FSH) and luteinizing hormone (LH) in group A were the highest (P<0.05),but the level of testosterone (T) was the lowest (P<0.05); the levels of anti-mullerian hormone (AMH) and serum inhibin B (INHB) in group A were lower than those in group B and group E (P<0.05),the normal sperm morphology rate in group B was higher than that in group A and group E (P<0.05); the percentage of forward moving sperm in group B was the highest (P<0.05). Pearson correlation analysis revealed that sperm concentration,normal sperm morphology rate,and percentage of forward moving sperm were negatively correlated with age,FSH,LH (P<0.05),and positively correlated with testicular volume,T,AMH,and INHB (P<0.05). NOA patients were grouped according to testicular histology and pathology. The INHB in the SCO group was the smallest of the three groups (P<0.05); the FSH and LH levels in the SCO group were higher than those in the MA group (P<0.05),while the 17β-estradiol (E2) levels in the HYPO group were higher than those in the SCO group (P<0.05). NOA patients were grouped according to the results of Micro-TESE surgical treatment. There was a statistically significant difference in AMH and INHB levels between the Micro-TESE positive and negative groups (P<0.05). The binary logistic regression analysis of factors affecting the Micro-TESE outcomes of NOA patients showed AMH was negatively correlated with the Micro-TESE outcome (OR=0.904,95%CI:0.91-1.08,P<0.05). 【Conclusion】 Age,FSH,LH,AMH,and INHB are correlated with sperm concentration,normal sperm morphology rate,and percentage of forward moving sperm. The INHB level was the lowest in the SCO group. The results of Micro-TESE in patients with NOA can be predicted by serum AMH level.

Non-exosomal non-coding RNAs (non-exo-ncRNAs) and exosomal ncRNAs (exo-ncRNAs) have been associated with the pathological development of myocardial infarction (MI). Accordingly, this analytical review provides an overview of current MI studies on the role of plasma non-exo/exo-ncRNAs. We summarize the features and crucial roles of ncRNAs and reveal their novel biological correlations via bioinformatics analysis. The following contributions are made: (1) we comprehensively describe the expression profile, competing endogenous RNA (ceRNA) network, and "pre-necrotic" biomarkers of non-exo/exo-ncRNAs for MI; (2) functional enrichment analysis indicates that the target genes of ncRNAs are enriched in the regulation of apoptotic signaling pathway and cellular response to chemical stress, etc.; (3) we propose an updated and comprehensive view on the mechanisms, pathophysiology, and biomarker roles of non-exo/exo-ncRNAs in MI, thereby providing a theoretical basis for the clinical management of MI.

Objective:To evaluate the therapeutic effect of micro-dissection testicular extraction (micro-TESE) combined with intracytoplasmic sperm injection (ICSI) technology, and guide the clinical treatment of non-obstructive azoospermia (NOA) with azoospermia factor (AZF) c-region deletion.Methods:Through retrospective study, the clinical data of NOA patients with AZFc deletion were analyzed who underwent asynchronous micro-TESE in Reproductive Medicine Centre of Peking University Third Hospital from January 2015 to December 2019. The clinical outcomes of ICSI in patients who successfully obtained sperm were followed up, including fertilization rate, good-quality embryo rate, clinical pregnancy rate, abortion rate and live birth rate.Results:A total of 47 patients with NOA caused by AZFc deletion underwent asynchronous micro-TESE and 28 cases successfully found spermatozoa during the operation. The sperm retrieval rate (SRR) was 59.6% (28/47). Totally 25 cases cryopreserved testicular spermatozoa and 15 cases underwent thawed-sperm ICSI and 14 of them found enough spermatozoa for ICSI. Among the 28 patients who successfully found sperm during the first micro-TESE operation, 14 gave up the use of sperm and another 14 later used the thawed sperm for ICSI. A total of 14 cryopreserved sperm ICSI cycles were carried out, followed by 11 embryo transfer cycles. Only one patient successfully gave birth to one health boy. After that 11 patients underwent the second synchronous micro-TESE and spermatozoa were all successfully found during the operation. Eleven cycles used fresh sperm for ICSI followed by 11 embryo transfer cycles. Finally, 3 patients successfully gave birth to 1 boy and 2 girls.Conclusion:Patients of NOA caused by AZFc deletion have a high probability of successfully obtaining spermatozoa in testis through micro-TESE for ICSI to breed offspring with their own biological characteristics. For patients failed in the first asynchronous procedure, the second synchronous micro-TESE with fresh spermatozoa for ICSI can be considered to improve the utilization rate of sperm and the final live birth rate.
