Background: s/Aims: Distal pancreatectomy with splenectomy (DPS) is a common surgical procedure for pancreatic body cancer.However, spleen-preserving distal pancreatectomy (SPDP) utilizing the Warshaw technique (WT) in malignancies is generally not favored due to concerns about inadequate resection. This study aims to assess the feasibility and oncologic outcomes of employing SPDP with WT in pancreatic body cancer. Methods: We conducted a retrospective analysis comparing 21 SPDP patients with 63 DPS patients matched by propensity score from January 2018 to November 2022. Clinical outcomes and follow-up data were analyzed using R. Results: Both groups exhibited similar demographic, intraoperative, and pathological characteristics, with the exception of a reduced number of total lymph nodes (p = 0.006) in the SPDP group. There were no significant differences in the rates of postoperative complications, recurrence, or metastasis. Local recurrence predominantly occurred in the central region as opposed to the spleen region.There were no cases of isolated recurrences in the splenic region. Median overall survival and recurrence-free survival times were 51.5 months for SPDP vs 30.5 months for DPS and 18.7 months vs 16.8 months, respectively (p > 0.05). The incidence of partial splenic infarction and left-side portal hypertension in the SPDP group was 28.6% (6/21) and 9.5% (2/21), respectively, without necessitating splenic abscess puncture, splenectomy, or causing bleeding from perigastric varices. Conclusions SPDP did not negatively impact local recurrence or survival rates in selected pancreatic body cancer patients. Further studies are necessary for validation.

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:To explore the effect of timely induction intervention on postpartum urination in primipara during vaginal delivery, so as to provide the evidence for preventing the occurrence of postpartum urinary retention and relieving the pain of primipara.Methods:This study adopted a randomized controlled trial design, and selected 400 cases of primipara who were hospitalized for vaginal delivery in the Obstetric Department of Dalian Women and Children's Medical Group Sports New Town Hospital from June 2021 to September 2022 as the study objects by convenience sampling method. They were divided into the intervention group and the control group with 200 cases each by random number table method, and the control group received routine postpartum care. Instruct active urination within 6 hours after delivery. The intervention received timely induction urination intervention. The general condition and bladder urine volume of the women in the intervention group were evaluated at 2, 4, 6 h after delivery, respectively, and personalized guidance was implemented, including the frequency of massage of the bottom of the uterus, the control of water intake, the selection of methods and timing of inducing urination, etc., and routine postpartum care was given when the women completed their first urination and had no complaints of discomfort. The first urination time, first urination volume, first bladder irritation during the first urination and the incidence of postpartum urinary retention in different periods were compared between the two groups.Results:The patients in the control group were (29.60 ± 3.20) years old, while the patients in the intervention group were (28.81 ± 3.42) years old. The first urination time in the intervention group was (6.89 ± 2.18) h, which was shorter than that in the control group (9.11 ± 3.86) h, and the difference was statistically significant ( t=-2.49, P<0.01). The first urination volume in the intervention group was (322.36 ± 120.15) ml, which was higher than that in the control group (262.93 ± 105.68) ml, and the difference was statistically significant ( t=3.39, P<0.05). The incidence of the first bladder irritation in the intervention group was 22.0%(44/200), which was lower than that in the control group 33.5%(67/200), and the difference was statistically significant ( χ2=6.60, P<0.05). The incidence of postpartum urinary retention within 24 h in the intervention group was 5.5%(11/200), which was lower than that in the control group 11.5%(23/200), and the difference was statistically significant ( χ2=4.63, P<0.05). The incidence of postpartum urinary retention within 1 week in the intervention group was 9.5%(19/200), which was lower than that in the control group 16.5%(33/200), and the difference was statistically significant ( χ2=4.33, P<0.05). There was no significant difference in the incidence of postpartum urinary retention within 24 to 72 h between the two groups ( P>0.05). Conclusions:Timely induction intervention can reduce the incidence of postpartum urinary retention, shorten the time of first urination, increase the volume of first urination and improve the comfort of first urination, which is worthy of clinical application.

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.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Heart failure is one of the main cardiovascular system diseases at present， and it is a clinical syndrome caused by changes in cardiac structure and function， resulting in impaired ejection function or ventricular filling. Therefore， heart failure has become the most important cardiovascular disease in the 21^st century. In recent years， the incidence of heart failure is increasing， and the survival rate of patients with heart failure is very low. Traditional Chinese medicine has rich experience in preventing and treating heart failure. With the modernization of traditional Chinese medicine， more and more attention has been paid to the research， development， and application of active ingredients in traditional Chinese medicine. Traditional Chinese medicine has unique advantages in improving the heart function of patients with heart failure by treating multiple targets and multiple pathways through syndrome differentiation. Astragalus membranacus， a traditional Chinese medicine， is a kind of medicine that benefits Qi and blood circulation and removes evil spirits. It has the functions of improving myocardial energy metabolism and hemodynamics， protecting myocardial muscle， and promoting angiogenesis. Astragalus membranaceus is often used to treat patients with heart failure， yielding remarkable results. In recent years， it has been found that astragaloside， Astragalus polysaccharide， quercetin， calyx isoflavones， and other main active ingredients of Astragalus membranacus can improve cardiac function and treat heart failure by inhibiting inflammatory response， myocardial apoptosis， and myocardial fibrosis. This paper reviewed the research progress of the action and mechanism of the active ingredients of Astragalus membranacus in the treatment of heart failure by studying relevant literature， with a view to providing a reference for its further research， development， and application in the prevention and treatment of heart failure.

Objective To investigate the effect of oral fish oil on wound healing and related indexes in patients with diabetic foot ulcer(DFU).Methods A randomized,double-blind,placebo-controlled design was used to recruit 68 patients with DFU aged 18-80 years old in the hospital,and the baseline clinical data of the patients were collected.The patients were randomly divided into experimental group(32 cases,fish oil soft capsule,3 g/d)and control group(33 cases,corn oil soft capsule,3 g/d)by random number generated by Ex-cel,and the intervention lasted for 12 weeks.The primary endpoints included the proportion of complete wound healing and healing area≥50%.The secondary endpoints included wound area,healing time,inflamma-tion index,glucose metabolism index,nutrition related index and wound reinfection.Additionally,the influen-cing factors of wound healing were analyzed.Results After intervention,the proportion of complete wound healing and healing area≥50%in the experimental group was significantly higher than that in the control group(P=0.007,0.039).In the subjects with complete wound healing,the mean healing time in the experi-mental group was shorter than that in the control group,but the difference was not statistically significant(P=0.132).The reduction area of wound area in the experimental group was significantly larger than that in the control group(P=0.045).The decrease of interleukin(IL)-6 and IL-8 in the experimental group was significantly higher than that in the control group(P<0.05).There was no significant difference in the reduc-tion of C-reactive protein(CRP),tumor necrosis factor-α(TNF-α),neutrophil-to-lymphocyte ratio(NLR),glycated hemoglobin A1c(HbA1c)and platelet-to-lymphocyte ratio(PLR)between the two groups(P>0.05).The improvement of prealbumin(PA)in the experimental group was higher than that in the control group,but the difference was not statistically significant(P>0.05).Multivariate logistic regression analysis showed that oral fish oil intervention(OR=6.771,95%CI:1.787-25.652),HbA1c(OR=4.149,95%CI:1.026-16.770)and ulcer type(OR=4.319,95%CI:1.026-18.173)were the influencing factors of wound healing(P<0.05).Conclusion Oral fish oil promotes wound healing in patients with DFU,which may be re-lated to improving the level of chronic inflammation in the body.

Pharmaceutical cocrystals are one of the effective strategies to improve the solubility and bioavailability of poorly water-soluble drugs. However, the phase transformation of cocrystals during dissolution can lead to the recrystallization of the parent drugs, and thus negating the solubility advantage of cocrystals. The introduction of suitable excipients into the cocrystal formulation may inhibit the phase transformation during dissolution, resulting in the enhanced dissolution and bioavailability of poorly soluble drugs. In addition, the complex gastrointestinal environment and absorption behavior of drugs can have significant impacts on the oral bioavailability of cocrystals. This review summarizes the recent studies of the dissolution and absorption of pharmaceutical cocrystals, and aims to provide guidance for the rational design of pharmaceutical cocrystal formulations.
