Cardiovascular diseases （CVD），a group of common diseases in clinical practice，are witnessing a steady rise in both incidence and mortality rates，posing a challenge to public health. Gualou Xiebai Banxiatang，originating from Synopsis of the Golden Chamber （《金匮要略》），was initially used to treat severe cases of chest impediment. The formula consists of Trichosanthis Fructus，Allii Macrostemonis Bulbus，Pinelliae Rhizoma，and Baijiu. It has a wide range of clinical applications，with therapeutic effects including moving Qi to relieve depression，activating Yang to dissipate mass，and expelling phlegm to alleviate chest congestion. In recent years，clinical research has confirmed that Gualou Xiebai Banxiatang，with or without modification，used alone or in combination with Western medicine，has definite effects in the treatment of CVD such as hyperlipidemia，coronary atherosclerotic heart disease，hypertension，heart failure，and arrhythmia. It can alleviate disease symptoms and reduce the risk of re-hospitalization. Basic research indicates that the mechanisms of Gualou Xiebai Banxiatang include improving endothelial functions，exhibiting anti-inflammatory properties，countering oxidative stress，preventing apoptosis，inhibiting ventricular remodeling，regulating mitochondrial functions，improving hemorheology，and modulating autophagy and neurotransmitters. This article reviews relevant articles in recent years with focuses on the compatibility，clinical application，and mechanism of Gualou Xiebai Banxiatang. This review is expected to provide a theoretical basis for the mechanism research and clinical application of this formula in treating CVD and to offer ideas and reference for in-depth research.

ObjectiveTo investigate the effect of Naoqingtong decoction （NQT） on the kidney damage and the inflammatory factors NOD-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain （ASC）， cysteinyl aspartate-specific proteinase-1 （Caspase-1）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in spontaneously hypertensive rats （SHRs）. MethodsTwenty-four SHRs were randomized into a model group， a low-dose （12.9 g·kg^-1·d^-1） NQT （NQT-L） group， a high-dose （25.8 g·kg^-1·d^-1） NQT group （NQT-H）， and a captopril （CTP， 20 mg·kg^-1·d^-1） group， with 6 rats in each group. In addition， 6 homozygous male Wistar-Kyoto rats were used as the control group. The control and model groups were administrated with the same amount of normal saline by gavage for 8 weeks. General behaviors of rats were observed during the intervention period， and the blood pressure was measured periodically. At the end of intervention， the body mass was weighed， and both kidneys were collected and weighed for the calculation of the renal index. Hematoxylin-eosin staining was performed to observe the pathological changes in the kidney tissue. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue. ResultsDuring the experiment period， the control group had normal mental status， food intake， and activity， while the model group showed thinning of hair， loss of luster， reduced activity， loss of appetite， fecal adhesion， and irritability， and some of the skin had scratches or blood scabs. The above symptoms were alleviated to different degrees after 8 weeks of NQT administration. An intelligent non-invasive sphygmomanometer was used to measure the tail artery pressure of rats， which showed that the systolic and diastolic blood pressure of rats in the model group was higher than that in the control group （P<0.01）. Compared with the model group， drug interventions lowered the systolic and diastolic blood pressure （P<0.05， P<0.01）. Compared with the control group， the model group showed severe pathological damage in the kidney tissue， which was alleviated in each drug intervention group. Compared with the control group， the model group showed up-regulated expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue （P<0.05， P<0.01）. Compared with the model group， the drug intervention groups showed down-regulated expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue （P<0.05， P<0.01）. ConclusionNQT can lower the blood pressure in SHRs by inhibiting the activation of NLRP3 inflammasomes， suppressing renal inflammation， and ameliorating hypertensive kidney damage.

[摘 要] 目的：探讨健脾复胃颗粒（JPFWG）通过调控IL-6/JAK/STAT3信号通路对胃癌前病变（PLGC）大鼠胃黏膜损伤的干预效果及其作用机制。方法：采用MNNG联合复合因素造模法建立PLGC模型大鼠，随机分为6组（20只/组）：空白组（未处理）、模型组（给予生理盐水）、维酶素组（0.05 g/mL维酶素）、JPFWG低剂量组（JPFWG-L，0.088 g/mL）、JPFWG中剂量组（JPFWG-M，0.176 g/mL）、JPFWG高剂量组（JPFWG-H，0.351 g/mL）。各治疗组大鼠分别给予相应药物处理12周后，麻醉处死动物并取胃组织标本。采用H-E染色法观察胃黏膜的病理变化，通过免疫组化、qPCR和WB法检测胃黏膜组织中IL-6介导的JAK/STAT3信号通路相关因子（包括IL-6、JAK、STAT3）及其下游靶基因c-Myc、cyclin D1的 mRNA和蛋白的表达水平。结果：与模型组相比，维酶素组和JPFWG-L、JPFWG-M、JPFWG-H组大鼠胃黏膜炎性细胞浸润均减少，病理状态改善以JPFWG-H组最明显；IL-6、JAK1、STAT3蛋白表达显著降低（P < 0.05或P < 0.01）；维酶素组和JPFWG-H组大鼠胃黏膜组织中c-Myc、cyclin D1的 mRNA和蛋白表达均显著降低（P < 0.05或P < 0.01）。结论：JPFWG能够改善PLGC大鼠胃黏膜的组织病理变化，其机制可能是通过调控IL-6/JAK/STAT3信号通路，进而下调c-Myc、cyclin D1的表达，从而阻断炎-癌转化过程。

Purpose: This study aimed to evaluate the outcomes and current status of reduced-port laparoscopic distal gastrectomy (RLDG) compared with multiport laparoscopic distal gastrectomy (MLDG) based on a 2019 nationwide survey of surgical gastric cancer treatments by the Korean Gastric Cancer Association (KGCA). Materials and Methods: The study was conducted retrospectively from March to December 2020 using data from the 2019 KGCA nationwide survey database. To compare RLDG and MLDG based on age, sex, body mass index, American Society of Anesthesiologists score, histological type, tumor invasion, and lymph node metastasis, propensity score matching was performed. Results: Of the 14,076 registered patients with gastric cancer, the five-port approach was the most favored for multiport gastrectomy, accounting for 6,396 (70.9%) cases, followed by the four-port approach, with 1,462 (16.2%) cases. The single-port approach was used in 303 (3.4%) cases, the two-port approach in 95 (1.1%) cases, and the three-port approach in 731 (8.1%) cases. RLDG was performed in 805 patients (6.4%), MLDG was conducted in 4,831 patients (34.3%), and 804 patients were 1:1 matched in each group. The average operation time was shorter in the RLDG (168.2±49.1 min vs. 179.5±61.5 min, P<0.001). No significant difference was found in blood loss (84.8±115.9 cc vs. 75.5±119.6 cc, P=0.152), overall complication rates (11.3% vs. 13.1%, P=0.254), or complications ≥ to grade IIIa (3.2% vs. 4.4%, P=0.240). Conclusions This study revealed that RLDG is a safe and effective surgical option for gastric cancer with the potential to offer shorter operation times without increasing the risk of complications.

Objective To explore the mediating role of activities of daily living (ADL) in pain and depressive symptoms in the elderly in China. Methods Utilizing the data from 2020 China Health and Retirement Longitudinal Study, 4403 Chinese elderly individuals aged ≥ 60 years old were selected as the research subjects. Depression Scale (CES-D 10) of the Center for Epidemiological Survey and ADL scale were used in the study. The PROCESS4.1 macro was used to test the mediating effect of daily living activities between pain and depressive symptoms, and the Bootstrap method was applied for verification of the mediating variables. Results A total of 2368 cases of depressive symptoms were detected in the elderly in China, with a detection rate of 53.78%. Pain was positively correlated with depressive symptoms (r=0.27, P<0.01), and activities of daily living were negatively correlated with pain and depressive symptoms (r=-0.27, -0.337, P<0.01). The results showed that the total effect value of pain on depressive symptoms was 0.33, the direct effect value was 0.24, and the mediating effect value of daily living activities was 0.09, accounting for 27.27%. Conclusion Pain and activities of daily living are important factors influencing depressive symptoms in the elderly, and activities of daily living play a partial mediating role in the relationship between pain and depressive symptoms in the elderly.

Objective To study the correlation between the changes of matrix metalloproteinase-9(MMP-9)and neutrophil/lymphocyte ratio(NLR)before and after the revascularization of acute ischemic stroke(AIS),so as to find biomarkers to predict the bleeding transformation risk of AIS patients.Methods From February 2022 to December 2022,161 patients admitted to the Stroke Center of Qujing Hospital Affiliated to Kunming Medical University with AIS werre divided in to the hemorrhagic transformation group and the non-hemorrhagic transfor-mation groupand treated with revascularization(intravenous thrombolysis,endovascular treatment,combined the intravenous thrombolysis with endovascular treatment).Among them,there were 46 cases in the hemorrhagic transformation group and 115 cases in the non hemorrhagic transformation group.And the general data,NLR value and MMP-9 before and after the revascularization were compared between the two groups.Results There was no statistical difference in general data between the two groups(all P>0.05)except for C-reactive protein in hemorrhagic transformation group and in non-hemorrhagic transformation group(P<0.001).The white blood cells,neutrophils,neutrophil percentage,neutrophil absolute value,lymphocyte absolute value,NLR and MMP-9 value in hemorrhagic transformation group were significantly higher than those in non-hemorrhagic transformation group before the treatment and there was a statistical significance(P<0.05).After revascularization,the indexes of blood routine and MMP-9 were significantly higher than those before the revascularization,and the increase in hemorrhagic transformation group was more obvious than that in non-hemorrhagic transformation group and there was a statistical significance(P<0.001),The ROC curve showed that the area under the curve(AUC)of NLR and MMP-9 predicting bleeding transformation after AIS revascularization were 0.74 and 0.90.Conclusion NLR,MMP-9 are associated with the risk of bleeding transformation in AIS patients after the revascularization and can they can be used as the predictive factors for bleeding transformation risk.

Corneal transplantation is an effective treatment for corneal blindness, and it is the only hope for patients with corneal blindness. Cornea has no blood vessels and no lymphatic vessels, which is called immune privilege organ, so the success rate of corneal transplantation is significantly higher than that of other organ transplantation, but the rejection reaction after corneal transplantation is still the main reason for the failure of corneal transplantation. The directional movement of immune cells to lymphoid tissue and inflammatory sites is the mainly immune response after organ transplantation. And the regulatory T cells(Treg)play a key role in immune regulation, which can induce immune tolerance by regulating and inhibiting the activation of effector T cells and reduce the rejection reaction after corneal transplantation. In addition, this review also discussed the effectiveness of applying cordyceps sinensis extract FTY720 to enhance the function of Treg. Based on this, we briefly reviewed the sources, mechanism of action and treatment of Treg after corneal transplantation, so as to provide some reference for the subsequent clinical application transformation and basic research.

Objective To study the effect and mechanism of paeonol(PAE)on renal interstitial fibrosis in rats.Methods The rats were randomly divided into sham operation(Sham)group,unilateral ureteral obstruction(UUO)group,PAE low dose(PAE-L)group,PAE medium dose(PAE-M)group,PAE high dose(PAE-H)group and irbesartan(IRB)group.Except for the Sham group,the UUO model was established in other groups.Each group was given a corresponding intervention for two weeks.Serum creatinine(Scr),blood urea nitrogen(BUN),serum 8-hydroxydeoxyguanosine(8-OHdG)levels,renal tissue superoxide dismutase(SOD),glutathione peroxidase(GPX)activities,α-smooth muscle actin(α-SMA),type Ⅰ collagen(Col-Ⅰ),fibronectin(FN),silent information regulator 1(SIRT1),nuclear factor E2-related factor 2(Nrf2)protein expression were detected;observe pathological changes of kidney tissue and calculate collagen volume fraction(CVF).Results Compared with the UUO group,the serum levels of Scr,BUN,and 8-OHdG in each dose group of PAE were decreased,the activities of SOD and GPX in kidney tissue were increased,the positive expressions of α-SMA,Col-Ⅰ and FN in kidney tissue were decreased,and the protein expressions of SIRT1 and Nrf2 were increased.Masson staining showed a decrease of CVF in renal tissue(all P<0.05),and HE staining showed a different degree of improvement in pathological changes such as inflammatory cell infiltration and tubular dilatation in renal tissue;PAE improves renal interstitial fibrosis in rats in a dose-dependent manner(P<0.05),and the effect of large dose PAE on renal interstitial fibrosis in rats was similar to that of IRB.Conclusion PAE can alleviate UUO-induced rat renal interstitial fibrosis and oxidative stress,and improve rat renal function.And this mechanism may be related to the activation of the SIRT1/Nrf2 signaling pathway.
