Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Objective:To compare the clinical efficacy between microscopic varicocelectomy and laparoscopic varicocelectomy in the treatment of varicocele(VC)with male infertility.Methods:A total of 307 patients who were diagnosed with VC complicated with male infertility and admitted to the Affiliated Hospital of Qingdao University from October 2018 to October 2022 were recruited for retrospective analysis.The patients were divided into the microscopic group(180 cases)and laparoscopic group(127 cases)according to the surgery method.The pre-and postoperative clinical data of these two groups were analyzed,including the degree of dilatation and reflux time of internal spermatic vein,hemodynamic parameters of testicular capsular artery,proportion of progressive motility spermato-zoa(PR),concentration of spermatozoa,proportion of normal morphology sperm,the pregnancy outcome of spouses and the incidence of complications related with surgery within 2 years postoperatively.Results:All the surgeries for the 307 patients in this study were successful.There was no significant difference in operation time,hospitalization time and management expenses between the microscop-ic group and the laparoscopic group(P＞0.05).Compared to the patients in laparoscopic group,the patients in the microscopic group received a better improvement in venous diameter,reflux time of spermatic veins and hemodynamic parameters of testicular capsular ar-tery(P＜0.05).Moreover,the semen analysis showed that the PR,spermatozoa concentration and proportion of normal morphology sperm in the microscopic group were also obviously increased than those in the laparoscopic group(P＜0.05).During the 2-year fol-low-up period,the conception rate of spouses in the microscopic group was 67.2％,while only 47.2％in the laparoscopic group,in which the difference was statistically significant(P＜0.05).Besides,the time-to-pregnancy(TTP)within 2 years postoperatively in the microscopic group was significantly shorter than that in the laparoscopic group(P＜0.05).Meanwhile,the incidence of adverse pregnancy outcomes in the microscopic group was also significantly lower than that in the laparoscopic group(P＜0.05).It is worth mentioned that the spontaneous conception rate of spouses with successful pregnancy in the microscopic group was also significantly higher than that in the laparoscopic group(P＜0.05).Severe complication such as testicular atrophy,bleeding and infection did not appear in both of two groups.However,the incidences of testicular hydrocele and recurrence of VC postoperatively in the laparoscopic group were significantly higher than those in the microscopic group(P＜0.05).Conclusion:Both microscopic varicocelectomy and laparoscopic varicocelectomy can be applied to the management of VC combined with male infertility.But microscopic varicocelectomy showed better clinical efficacy in improving the testicular hemodynamic parameters,semen quality,pregnancy outcome and postopera-tive complications,which is worthy of further clinical applications.

Objective:To investigate the safety and clinical effect of testis-sparing microsurgery(TSMS)in the treatment of benign testis tumor(BTT).Methods:We retrospectively analyzed the clinical data on 16 cases of BTT treated in the Department of Andrology of the Affiliated Hospital of Qingdao University from October 2020 to February 2023.The median age of the patients was 23 years.All the tumors were unilateral,7 in the left and 9 in the right side,with a median diameter of 1.85 cm(1.0-3.5 cm).The patients all underwent color Doppler flow imaging(CDFI),MRI,semen analysis and examination of serum T,alpha-fetoprotein(AFP),human chorionic gonadotropin(HCG)and lactate dehydrogenase(LDH),followed by TSMS.The boundaries between the tumors and normal testis tissue were accurately identified under the microscope,and the tumors and the adjacent normal testis tissue 2 mm from their margins were excised completely.Bipolar coagulation forceps were used for wound hemostasis to maximally preserve the normal testis tissue.The resected specimens were subjected to fast frozen pathology intraoperatively,and the patients were followed up for 14-40 months by regular scrotal CDFI,MRI and examinations of serum T and semen parameters.Results:The levels of serum T,AFP,HCG and LDH and semen parameters were all within the normal range preoperatively.TSMS were successfully completed in all the cases,and all were pathologically confirmed as BTT according to the latest edition of WHO Classification of Tumors:Urinary and Male Genital Tumors.CDFI showed normal blood supply within the testis tissue at 1 month after surgery.No signs of intra-testicu-lar tumor residue,recurrence or metastasis,nor significant changes in the levels of serum T,AFP,HCG or LDH or semen parameters were observed during the follow-up as compared with the baseline.Natural conception was achieved in 2 cases at 16 and 18 months re-spectively after surgery.Conclusion:BTT can be differentially diagnosed by CDFI and MRI before surgery and confirmed by histo-pathology.TSMS can achieve complete excision of the tumor,maximal sparing of the normal testis tissue and thereby effective preserva-tion of male fertility.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To investigate the protective effect and possible mechanism of sulforaphane (SFN) on acute liver injury in mice induced by diquat (DQ) poisoning.Methods:Forty-eight male C57BL/6 mice were divided into Control group, DQ model group (DQ group), SFN intervention group (DQ+SFN group), and SFN control group (SFN group) using a random number table method, with 12 mice in each group. Acute liver injury mice model was established by one-time intraperitoneal injection of 1 mL of 40 mg/kg DQ solution at once. SFN group was injected with 1 mL of ddH 2O. After 4 hours of molding, 0.5 mL of 5 mg/kg SFN solution was injected into the peritoneal cavity of the DQ+SFN group and SFN group, once daily for 7 consecutive days. DQ group and Control group were injected with an equal amount of ddH 2O. Then, the mice were euthanized to collect liver tissue and blood samples, and the levels of plasma biomarkers alanine aminotransferase (ALT) and aspartate aminotransferase (AST), as well as oxidative stress indicators such as superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA) in liver tissue were measured. The changes of liver structure were observed under transmission electron microscopy. The apoptosis and reactive oxygen species (ROS) level in liver tissue were observed under fluorescence microscope. Western blotting was used to detect the protein expressions of nuclear factor E2-related factor 2 (Nrf2), hemeoxygenase-1 (HO-1), Kelch-like ECH-associated protein 1 (Keap1), and cleaved caspase-9 in liver tissue. Results:Compared with the Control group, the liver mitochondria in the DQ group showed severe swelling, partial dissolution of the matrix, and cristae rupture and loss; the levels of plasma AST and ALT significantly increased, the MDA content in the liver increased, the activities of SOD and GSH decreased, the level of ROS significantly increased, the number of apoptotic cells in the liver significantly increased, the protein expressions of Nrf2 and HO-1 significantly decreased, and the protein expressions of Keap1 and cleaved caspase-9 significantly increased. Compared with the DQ group, the mitochondrial damage in the DQ+SFN group was reduced, the levels of plasma AST and ALT were significantly reduced [ALT (U/L): 58.22±4.39 vs. 79.94±3.32, AST (U/L): 177.64±8.40 vs. 219.62±11.60, both P < 0.01], the liver MDA content decreased, and the activities of SOD and GSH increased [MDA (μmol/g: 5.63±0.18 vs. 5.96±0.29, SOD (kU/g): 102.05±4.01 vs. 84.34±5.34, GSH (mmol/g): 16.32±1.40 vs. 13.12±1.84, all P < 0.05], the production of ROS in liver tissue was significantly reduced [ROS (fluorescence intensity): 115.90±10.89 vs. 190.70±10.16, P < 0.05], and apoptotic cells were significantly reduced (cell apoptosis index: 4.39±1.00 vs. 10.71±0.56, P < 0.01), the protein expressions of Nrf2 and HO-1 were significantly increased, while the protein expressions of Keap1 and cleaved caspase-9 were significantly decreased (Nrf2/β-actin: 1.15±0.04 vs. 0.93±0.05, HO-1/β-actin: 1.75±0.12 vs. 0.78±0.04, Keap1/β-actin: 1.00±0.14 vs. 1.28±0.13, cleaved caspase-9/β-actin: 1.31±0.12 vs. 1.81±0.09, all P < 0.05). However, there was no statistically significant difference in various indicators between the SFN group and the Control group. Conclusion:SFN can activate the Keap1/Nrf2 signaling pathway to alleviate DQ induced acute liver injury in mice.

OBJECTIVE: To compare the expected population impact of benefit and risk of aspirin treatment strategies for the primary prevention of cardiovascular diseases recommended by different guidelines in the Chinese Electronic Health Records Research in Yinzhou (CHERRY) study. METHODS: A decision-analytic Markov model was used to simulate and compare different strategies of aspirin treatment, including: Strategy ①: Aspirin treatment for Chinese adults aged 40-69 years with a high 10-year cardiovascular risk, recommended by the 2020 Chinese Guideline on the Primary Prevention of Cardiovascular Diseases; Strategy ②: Aspirin treatment for Chinese adults aged 40-59 years with a high 10-year cardiovascular risk, recommended by the 2022 United States Preventive Services Task Force Recommendation Statement on Aspirin Use to Prevent Cardiovascular Disease; Strategy ③: Aspirin treatment for Chinese adults aged 40-69 years with a high 10-year cardiovascular risk and blood pressure well-controlled (< 150/90 mmHg), recommended by the 2019 Guideline on the Assessment and Management of Cardio-vascular Risk in China. The high 10-year cardiovascular risk was defined as the 10-year predicted risk over 10% based on the 2019 World Health Organization non-laboratory model. The Markov model simulated different strategies for ten years (cycles) with parameters mainly from the CHERRY study or published literature. Quality-adjusted life year (QALY) and the number needed to treat (NNT) for each ischemic event (including myocardial infarction and ischemic stroke) were calculated to assess the effectiveness of the different strategies. The number needed to harm (NNH) for each bleeding event (including hemorrhagic stroke and gastrointestinal bleeding) was calculated to assess the safety. The NNT for each net benefit (i.e., the difference of the number of ischemic events could be prevented and the number of bleeding events would be added) was also calculated. One-way sensitivity analysis on the uncertainty of the incidence rate of cardiovascular diseases and probabilistic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted. RESULTS: A total of 212 153 Chinese adults, were included in this study. The number of people who were recommended for aspirin treatment Strategies ①-③ was 34 235, 2 813, and 25 111, respectively. The Strategy ③ could gain the most QALY of 403 [95% uncertainty interval (UI): 222-511] years. Compared with Strategy ①, Strategy ③ had similar efficiency but better safety, with the extra NNT of 4 (95%UI: 3-4) and NNH of 39 (95%UI: 19-132). The NNT per net benefit was 131 (95%UI: 102-239) for Strategy ①, 256 (95%UI: 181-737) for Strategy ②, and 132 (95%UI: 104-232) for Strategy ③, making Strategy ③ the most favorable option with a better QALY and safety, along with similar efficiency in terms of net benefit. The results were consistent in the sensitivity analyses. CONCLUSION The aspirin treatment strategies recommended by the updated guidelines on the primary prevention of cardiovascular diseases showed a net benefit for high-risk Chinese adults from developed areas. However, to balance effectiveness and safety, aspirin is suggested to be used for primary prevention of cardiovascular diseases with consideration for blood pressure control, resulting in better intervention efficiency.
