Xiaoji Yinzi is one of the classic prescriptions for treating urinary diseases， originated from the Yan's Prescriptions to Aid the Living （Yan Shi Ji Sheng Fang） written by YAN Yonghe in the Song dynasty. Xiaoji Yinzi is composed of Rehmanniae Radix， Cirsii Herba， Talcum， Akebiae Caulis， Typhae Pollen， Nelumbinis Rhizomatis Nodus， Lophatheri Herba， Angelicae Sinensis Radix， Gardeniae Fructus， and Glycyrrhizae Radix et Rhizoma and has the effects of cooling blood and stopping bleeding， draining water and relieving stranguria. The medical experts of later generations have inherited the original prescription recorded in the Yan's Prescriptions to Aid the Living， while dispute has emerged during the inheritance of this prescription. In this study， the method of bibliometrics was employed to review and analyze the ancient documents and modern clinical studies involving Xiaoji Yinzi. The results showed that Xiaoji Yinzi has two dosage forms： powder and decoction. According to the measurement system in the Song Dynasty， the modern doses of hers in Xiaoji Yinzi were transformed. In the prepration of Xiaoji Yinzi powder， 149.2 g of Rehmanniae Radix and 20.65 g each of Cirsii Herba， Talcum， Akebiae Caulis， stir-fried Typhae Pollen， Nelumbinis Rhizomatis Nodus， Lophatheri Herba， wine-processed Angelicae Sinensis Radix， stir-fried Gardeniae Fructus， and stir-fried Glycyrrhizae Radix et Rhizoma are grounded into fine powder with the particle size of 4-10 meshes and a decocted with 450 mL water to reach a volume of 240 mL. After removal of the residue， the decoction was taken warm before meals， 3 times a day （i.e.， 7.77 g Rehmanniae Radix and 0.97 g each of the other herbs each time）. In the preparation of Xiaoji Yinzi decoction， 20.65 g each of the above 10 herbs are used， with stir-fried Typhae Pollen， wine-processed Angelica Sinensis Radix， stir-fired Gardeniae Fructus， stir-fired Glycyrrhizae Radix et Rhizoma， and raw materials of other herbs. Xiaoji Yinzi is specialized in treating hematuresis and blood stranguria due to heat accumulation in lower energizer， which causes injury of the blood collaterals of gallbladder and dysfunction of Qi transformation. In modern clinical practice， Xiaoji Yinzi is specifically used for treating urinary diseases and can be expanded to treat diseases of the cardiovascular system and other systems according to pathogenesis. The comprehensive research on the key information could provide a scientific reference for the future development of Xiaoji Yinzi.

Objective:To evaluate the clinical outcomes of combined complete preservation of chordal structure mitral valve replacement (C-MVR) with total anatomical arterial myocardial revascularization (TACR) in coronary patients with moderate-to-severe or severe ischemic mitral regurgitation (IMR).Methods:This is a retrospective multi-center case series study. Data were retrospectively collected from 127 patients with coronary artery disease with moderate to severe or severe IMR who received TACR with C-MVR from July 2015 to April 2024 in 13 hospitals in China. There were 90 males and 37 females, aged (56.5±10.7) years (range: 33 to 74 years). Perioperative data and follow-up data including left ventricular ejection fraction, left ventricular end-diastolic diameter, and patency rate of arterial grafts of patients were collected. Comparisons were made using paired sample t-test or χ2 test. Results:In this cohort of 127 patients, 67 underwent concurrent tricuspid valve repair. During surgery, 113 grafts of the left internal mammary artery (LIMA), 127 grafts of the left radial artery, 80 grafts of the right radial artery, and 110 grafts of the right internal mammary artery (RIMA) were harvested. The number of the distal anastomosis was 4.2±0.4 (range: 3 to 5). The aortic cross-clamp time and cardiopulmonary bypass time were (97.5±23.4) minutes (range: 90 to 161 minutes) and (145.4±19.2) minutes (range: 101 to 210 minutes), respectively. There was one operative death. Intraoperative placement of an intra-aortic balloon pump was performed in 21 patients to improve the left ventricular ejection. No sternal ischemic occurred. All patients completed follow-up, with a mean follow-up period of (64.3±7.5) months (range: 4 to 110 months). No major cerebrovascular events occurred during the follow-up period, and all patients survived. Left ventricular ejection fraction improved postoperatively (55.0%±5.3% vs. 41.0%±15.3%, t=17.23, P<0.01). The proportion of patients with New York Heart Association functional class ≤2 increased postoperatively (23.6% (30/127) vs. 87.3% (110/126), χ2=103.77, P<0.01). The proportion of patients with Canadian Cardiovascular Society Angina Classification ≤3 decreased postoperatively (4.8% (6/126) vs. 78.7% (100/127), χ2=142.19, P<0.01). The left ventricular end-diastolic diameter decreased postoperatively ((5.70±4.50) cm vs. (6.10±0.23) cm, t=12.15, P<0.01). Coronary multi-detector computed tomography angiography (MDCTA) follow-up was conducted for (60.5±11.7) months (range: 6 to 109 months) postoperatively. MDCTA confirmed the patency rates of the grafts: 96.4% (108/112) for the LIMA grafts, 88.9% (112/126) for the left radial artery grafts, 93.7% (74/79) for the right radial artery grafts, and 90.9% (100/110) for the free RIMA grafts. No significant differences in graft patency rates were observed between the arterial grafts ( χ2=5.24, P=0.155). Conclusion:The results of this multi-centre study demonstrate satisfactory mid-term results of C-MVR with TACR for the treatment of coronary artery disease with moderate to severe or severe IMR.

Since 1968, surgical techniques for aortic dissection type A have rapidly advanced, significantly improving patients' outcomes. In recent years, various approaches to aortic root management have emerged. This article provides a comprehensive overview of these approaches.

Heart failure is a group of complex clinical syndromes in the middle and late stages of cardiovascular diseases.Mitochondrial homeostasis imbalance is one of the pathological mechanisms in the occurrence and development of heart failure.This article revolved around the"yin-yang theory"in TCM and explained the pathological mechanism of heart failure through mitochondrial homeostasis.Heart failure is the syndrome of deficiency in nature and excess in superficiality fundamental.Its basic pathogenesis is"yang deficiency and yin excess".Based on the deficiency of heart yang qi and the stagnation of yin pathogens,the combination of deficiency and excess runs through the entire disease.Mitochondrial homeostasis imbalance is a manifestation of yin-yang imbalance at the cellular micro level,mainly manifested as inhibition of mitochondrial biosynthesis,mitochondrial dynamics imbalance,mitophagy disorder,etc.,which affects mitochondrial structure and function and leads to abnormal myocardial energy metabolism.Therefore,based on the"yin-yang theory",the basic treatment method is to"tonify deficiency and damage excess"to regulate mitochondrial biosynthesis,mitochondrial dynamics,and mitophagy,thereby maintaining mitochondrial homeostasis and improving myocardial energy metabolism,which is of great significance for the prevention and treatment of heart failure.

ObjectiveTo study the effect and mechanism of Yixintai on mitochondrial fission proteins in the rat model of chronic heart failure. MethodTen of 60 SD rats were randomly selected as the sham operation group， and the remaining 50 rats were subjected to ligation of the left anterior descending coronary artery for the modeling of heart failure post myocardial infarction. The successfully modeled rats were randomized into model， low-， medium-， and high-dose （1.4， 2.8， and 5.6 g·kg^-1， respectively） Yixintai， and trimetazidine （10 mg·kg^-1） groups. The rats were administrated with corresponding doses of drugs by gavage， and the rats in the model group and sham operation group were given an equal volume of normal saline by gavage for 28 consecutive days. Enzyme-linked immunosorbent assay （ELISA） was then employed to measure the levels of amino-terminal pro-B-type natriuretic peptide （NT-pro BNP）， B-type natriuretic peptide （BNP）， and adenosine triphosphate （ATP） in the serum. Color Doppler ultrasound imaging was conducted to examine the cardiac function indicators. Hematoxylin-eosin staining and Masson staining were conducted to observe the pathological changes in the heart， and Image J was used to calculate collagen volume fraction （CVF）. Transmission electron microscopy was employed to observe the ultrastructural changes of myocardial cells. Terminal-deoxynucleoitidyl transferase-mediated nick-end labeling （TUNEL） was employed to measure the apoptosis rate of myocardial cells. Western blot was employed to determine the protein levels of mitochondrial fission protein 1 （Fis1） and mitochondrial fission factor （Mff） in the outer mitochondrial membrane of the myocardial tissue. ResultCompared with the sham operation group， the model group showed elevated levels of NT-pro BNP and BNP in the serum， decreased ATP content， left ventricular ejection fraction （LVEF）， and left ventricular fraction shortening （LVFS）， increased left ventricular end-diastolic diameter （LVIDd） and left ventricular end-systolic diameter （LVIDs）， disarrangement of myocardial cells， inflammatory cell infiltration， increased collagen fibers and CVF， damaged myocardium and mitochondria， and increased apoptosis rate of myocardial cells， and up-regulated expression of Fis1 and Mff in the cardiac tissue （P<0.01）. Compared with the model group， different doses of Yixintai and trimetazidine lowered the serum levels of NT-pro BNP and BNP （P<0.05）， increased the ATP content （P<0.05）， increased LVEF and LVFS （P<0.01）， decreased LVIDd and LVIDs （P<0.01）. Moreover， the drugs alleviated the myocardial inflammatory damage and fibrosis， reduced CVF （P<0.01）， repaired the myocardial mitochondrial structure， and decreased the apoptosis rate of myocardial cells （P<0.01）. Medium- and high-dose Yixintai and trimetazidine down-regulated the expression of Fis1 and Mff in the myocardial tissue （P<0.05）. ConclusionYixintai can improve mitochondrial structure， reduce myocardial cell apoptosis， and improve cardiac function by inhibiting the expression of Fis1 and Mff in the myocardial tissue.

Objective:Exploring the clinical effects of silicone silver ion foam dressing in managing scalp donor site wounds in burn patients.Methods:A retrospective analysis was conducted on the clinical data of burn patients admitted to the 940th Hospital of Joint Logistics Support Force of PLA from January 2020 to January 2023. Patients underwent intraoperative harvesting of split-thickness skin grafting to repair deep burn wounds, with the denuded scalp area covered by either silicone silver ion foam dressing (Group A) or petrolatum gauze (Group B). Comparison of the following 5 parameters between the two groups: (1) Postoperative wound healing time. (2) Initial dressing change pain score was assessed using the numeric rating scale (NRS). 0 points indicated no pain, 1-3 points indicated mild pain, 4-6 points indicated moderate pain, and 7-10 points indicated severe pain. (3) Number of dressing changes. (4) Secondary trauma score, with a total score ranging from 1 to 3, where a higher score indicates more severe trauma. (5) Proportion of wounds healed to grade A (number of grade A healed cases/total number of cases in each group×100%). Depending on the data type, between-group comparisons were performed using t-test, Wilcoxon rank-sum test, or chi-square test. P<0.05 was considered a statistically significant difference. Results:A total of 60 patients, with 30 in each Group A and Group B, were included in the study. Group A was comprised of 18 males and 12 females, with an average age of (29.4±16.6) years. The burn area was (21.43±5.66)% of the total body surface area (TBSA), and the area of skin taken from the scalp was (1.80±0.61)% of TBSA. Group B was comprised of 20 males and 10 females, with an average age of (30.2±16.2) years. The burn area was (21.37±5.67)% of TBSA, and the area of skin taken from the scalp was (1.78±0.63)% of TBSA. No statistically significant differences were observed in gender distribution, age, burn area, and scalp area between the two groups( P>0.05). The wound healing time in the denuded scalp area was shorter in Group A than in Group B [(5.97±0.41) days vs. (6.93±0.58) days, t=-7.40, P<0.001]. The initial NRS pain score during dressing change was lower in Group A than in Group B [3.0 (2.0, 4.0) points vs. 5.5 (4.0, 6.0) points, Z=-4.82, P<0.001]. Group A had fewer frequency of dressing changes compared to Group B [2 (2, 2) vs. 4 (3, 5), Z=-6.64, P<0.001]. The secondary injury score was lower in Group A than in Group B [1 (1, 1) points vs. 3 (3, 3) points, Z=-7.08, P<0.001]. The proportion of grade A healing was 96.7% (29/30) in Group A and 90.0% (27/30) in Group B, with no statistically significant difference between the two groups ( χ2=0.27, P=0.605). Conclusion:The application of silicone silver ion foam dressing to cover the denuded scalp area of burn patients significantly improves therapeutic efficacy compared to petrolatum gauze. It can shorten wound healing time, reduce the frequency of dressing changes, alleviate pain, minimize the occurrence of secondary injuries, and enhance patient comfort.
