ObjectiveTo elucidate the underlying mechanism through which Zhuluan decoction suppresses excessive autophagy in human ovarian granulosa cells (KGN) and ameliorates premature ovarian insufficiency (POI) via the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway. MethodsThe optimal concentration of cyclophosphamide for inducing a POI model in KGN cells was identified via the cell counting kit-8 (CCK-8) assay. Subsequently, the impacts of varying concentrations of Zhuluan decoction-containing serum on the viability of the KGN cell model were assessed. After the optimal drug concentration was determined, KGN cells were categorized into the following groups: blank control (20% blank serum), model (20% blank serum + 5 μmol·L-1 cyclophosphamide), Zhuluan decoction-containing serum (20% Zhuluan decoction-containing serum + 5 μmol·L-1 cyclophosphamide), autophagy inhibitor (20% blank serum + 5 μmol·L-1 cyclophosphamide + 20 μmol·L-1 chloroquine phosphate), autophagy inhibitor + Zhuluan decoction-containing serum (20% Zhuluan decoction-containing serum + 5 μmol·L-1 cyclophosphamide + 20 μmol·L-1 chloroquine phosphate), and estradiol valerate (20% estradiol valerate-containing serum + 5 μmol·L-1 cyclophosphamide). Following 48 hours of incubation, flow cytometry was utilized to measure the apoptosis rate of KGN cells in each group. Western blotting was employed to quantify the protein levels of PI3K, phosphorylated (p)-Akt, Akt, p-mTOR, and mTOR, along with the expression levels of autophagy-related proteins such as Beclin1, autophagy-related 5 homolog (ATG5), and microtubule-associated protein 1 light chain 3 (LC3), in each group. Additionally, monodansylcadaverine (MDC) staining was performed to evaluate the extent of autophagy in each group. ResultsIncubation of KGN cells with 5 μmol·L-1 cyclophosphamide for 48 h successfully established a POI model, marked by a significant inhibition of KGN cell proliferation. Notably, the inhibitory effect of cyclophosphamide on KGN cell proliferation exhibited a positive correlation with its concentration. Zhuluan decoction-containing serum at 20% and 30% promoted cell proliferation and mitigated the inhibitory effect of cyclophosphamide on KGN cell proliferation, with comparable therapeutic efficacy observed at both concentrations. Compared with the blank control group, the model group displayed an elevated apoptosis rate (P<0.01), reduced protein levels of PI3K, p-Akt, and p-mTOR (P<0.01), increased protein levels of Beclin1, LC3, and ATG5 (P<0.01), no significant alterations in the protein levels of Akt and mTOR, and an enhanced MDC autophagy fluorescence intensity (P<0.01). In comparison to that the model group, the apoptosis rates in the blank control group, model group, Zhuluan decoction-containing serum group, autophagy inhibitor group, autophagy inhibitor + Zhuluan decoction-containing serum group, and estradiol valerate group all reduced (P<0.05, P<0.01), with the most pronounced reduction observed in the autophagy inhibitor + Zhuluan decoction-containing serum group. The protein levels of PI3K, p-Akt, and p-mTOR were higher in other groups than in the model group (P<0.05, P<0.01), being the highest in the autophagy inhibitor + Zhuluan decoctio-containing serum group (P<0.01). The protein levels of Beclin1 and ATG5 were lower in other groups than in the model group (P<0.05, P<0.01). The expression level of LC3 declined in the Zhuluan decoction-containing serum group and the estradiol valerate group (P<0.05, P<0.01), while it decreased without statistical significance in the autophagy inhibitor group and the autophagy inhibitor + Zhuluan decoction-containing serum group. ConclusionZhuluan decoction may activate the PI3K/Akt/mTOR pathway to inhibit excessive autophagy and counteract the detrimental effects of cyclophosphamide on the KGN cell model, thus managing POI.

ObjectiveThis paper aims to investigate the protective effects of the Tanyu Tongzhi Youhua prescription(TYTZP) against myocardial ischemia/reperfusion injury in rats via regulation of the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) signaling pathway. MethodsFifty-six 8-week-old male Sprague-Dawley (SD) rats were randomly divided into sham group, model group, ticagrelor group (32.4 mg·kg-1), RU320521 (RU.521cGAS inhibitors) group (5 mL·kg-1), groups of TYTZP with low dose (3.6 g·kg-1), medium dose (7.2 g·kg-1), and high dose (14.4 g·kg-1), with eight rats per group. The ticagrelor group and groups of TYTZP with different doses received pre-treatment for seven days according to their respective protocols. The RU.521 group received an intraperitoneal injection one hour before modeling. A rat model of the no-reflow phenomenon in myocardial ischemia/reperfusion injury was established by ligating the left anterior descending coronary artery in situ. Myocardial no-reflow area was determined by thioflavin staining. Histopathological morphology of myocardial tissue was observed via hematoxylin and eosin (HE) staining. Cardiac function was detected by echocardiography. Myocardial microcirculation function change was observed by using real-time myocardial contrast echocardiography. The myocardial enzyme levels in the serum were measured by serum biochemical analysis. The double-stranded DNA (dsDNA) levels were detected by using PicoGreen. The protein expression of cGAS, STING, and nuclear factor-κB (NF-κB) p65 in myocardial tissue was detected by Western blot. The levels of cardiac troponin Ⅰ (cTNⅠ), cardiac troponin T (cTNT), interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) in the peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA). ResultsCompared with the sham group, the model group showed a significantly increased myocardial no-reflow area (P<0.01). Myocardial fiber rupture and disarray and inflammatory cell infiltration were observed by HE staining. The ultrasound results indicated that left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) (P<0.01) were significantly decreased. Real-time myocardial contrast echocardiography showed that the peak time of myocardial blood perfusion was significantly prolonged (P<0.01), and the levels of creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH), cTNⅠ, cTNT, and dsDNA were significantly elevated (P<0.01). Western blot results showed that the myocardial protein expressions of cGAS, STING, and NF-κB p65 were upregulated (P<0.01). ELISA results showed that the inflammatory factors in the serum such as IL-6, IL-1β, and TNF-α were increased (P<0.01). Compared with the model group, the group of the TYTZP significantly reduced the levels of myocardial enzyme, troponins, and dsDNA (P<0.01, P<0.05), improved cardiac function and myocardial microcirculation, alleviated histopathological morphology and inflammatory infiltration, inhibited activation of the cGAS/STING pathway, reduced the expression of NF-κB p65 (P<0.01, P<0.05), and inhibited inflammatory response. ConclusionThe TYTZP mitigates the no-reflow phenomenon in myocardial ischemia/reperfusion injury, and its mechanism is associated with inhibiting the activation of the cGAS/STING pathway and attenuating inflammatory responses.

ObjectiveThis paper aims to investigate the effects of icariin on spermatogenesis in mice with exercise-induced fatigue and explore the underlying mechanisms. MethodsICR male mice were screened by swimming and randomly divided into normal group, model group, vitamin C group, icariin groups with low, medium, and high doses, and medium-dose icariin+N-nitro-L-arginine methyl ester (L-NAME) group, with 10 mice per group. Except for the normal group, all the other groups underwent weighted swimming training to establish an exercise-induced fatigue model. No gavage was administered during the first two weeks of the weighted training. From week three to four, the icariin groups with low, medium, and high doses received 0.03, 0.06, and 0.12 g·kg-1 icariin via gavage, respectively. The vitamin C group received 0.2 g·kg-1 vitamin C. The L-NAME group received 0.06 g·kg-1 icariin and 0.01 g·kg-1 L-NAME via intraperitoneal injection. The normal and model groups received equivalent physiological saline. After the experiment, body weight and the last exhaustive swimming time were recorded. Blood urea nitrogen (BUN), lactate (LA), lactate dehydrogenase (LDH), malondialdehyde (MDA), testicular testosterone (T), testicular Ca2+/Mg2+-adenosine triphosphatase (ATPase) (micro-assay), and the levels of testicular cyclic guanosine monophosphate (cGMP) were measured by using kits. Sperm CD46 levels were detected by flow cytometry. Testicular seminiferous tubules were observed via hematoxylin-eosin (HE) staining, and the testicular morphometric score (TMS) was used to evaluate the spermatogenic function. Protein expression of regucalcin (RGN, SMP30), cGMP-dependent protein kinase 1 (PKG), and cGMP-dependent protein kinase anchoring protein (GKAP1) was detected by Western blot. Testicular regucalcin expression was examined by immunofluorescence (IF). The epididymal sperm quality of mice was observed under a microscope. Fluorescence-stained sections of stimulated by retinoic acid gene 8 (STRA8), synaptonemal complex protein 3 (SCP3), and transition protein 1(TNP1) in testicular seminiferous tubules were assessed by immunohistochemistry (IHC). ResultsCompared with the normal group, the model group showed decreased body weight and exhaustive swimming time (P<0.01), significantly increased fatigue markers (LA, LDH, and BUN) and lipid peroxidation product MDA (P<0.01), reduced testicular RGN, PKG, GKAP1, testosterone, Ca2+/Mg2+-ATPase, and cGMP levels (P<0.01), decreased sperm motility, sperm count, and TMS scores, and downregulated the expression of STRA8, SCP3, and TNP1. Compared with the model group, the icariin group with high dose exhibited increased exhaustive swimming time (P<0.01), reduced LA, LDH, BUN, and MDA levels (P<0.01), elevated superoxide dismutase (SOD) (P<0.01), upregulated testicular RGN, PKG, GKAP1, testosterone, Ca2+/Mg2+-ATPase, and cGMP levels (P<0.01), improved sperm motility, sperm count, and TMS scores, and enhanced STRA8, SCP3, and TNP1 expression. Compared with the L-NAME group, the icariin group with medium dose showed increased expression of STRA8, SCP3, and TNP1 in the testicular tissue (P<0.01) and elevated cGMP and GKAP1 levels (P<0.01). ConclusionExercise-induced fatigue reduces the expression of RGN and cGMP/PKG/GKAP1 in mice, thereby causing abnormal spermatogenesis and impairing reproductive function in mice. Icariin ameliorates spermatogenic dysfunction in exercise-induced fatigue mice by promoting the expression of RGN and cGMP/PKG/GKAP1, thereby mitigating the damage of exercise-induced fatigue to the reproductive system.

Objective To compare and analyze the changes in the use of lung cancer therapeutic drugs before and after the national initiation of health insurance negotiations, and to study the impact of a series of policies on the use of lung cancer drugs. Methods Descriptive statistical methods were used analyze the basic situation of lung cancer patients and the changes of corresponding therapeutic drugs in Peking University People's Hospital from 2014 to 2020, as well as to the hospital procurement data of lung cancer therapeutic drugs in the database of the Chinese Medicine Economic Information. Results From 2014 to 2020, the total cost per capita of lung cancer patients showed a trend of first increasing and then decreasing, increasing before the national drug negotiation and gradually decreasing after the negotiation. After 2017, the use of small ATC categories such as VEGF/VEGFR inhibitors and EGFR tyrosine kinase inhibitors increased significantly, along with a rise in the number of monoclonal antibody varieties. The DDDs of osimertinib, anlotinib, alectinib, crizotinib and other drugs in the medical insurance list increased significantly, and the average daily cost decreased significantly. Conclusion The number of hospitalization days for lung cancer patients had continued to shorten in recent years, and the structure of drug use had changed significantly. The adjustment of the medical insurance catalog had led to more innovative lung cancer drugs showing the trend of volume up and price down.

Objective To investigate the regulatory mechanism of transforming growth factor-β1 (TGF-β1) in different types of mitral valvular disease (MVD) with atrial fibrillation (AF). Methods From August 2011 to August 2012, patients with moderate to severe MVD accompanied by AF who required mitral valve replacement at the Department of Cardiovascular Surgery, West China Hospital, Sichuan University, were included. Based on echocardiographic results, patients were divided into two groups: a mitral regurgitation (MR) with AF (MR-AF) group and a mitral stenosis (MS) with AF (MS-AF) group. Left atrial tissue samples were collected during surgery. Techniques such as enzyme-linked immunosorbent assay, real-time fluorescence quantitative polymerase chain reaction, immunohistochemistry, and Western blotting were used to detect key molecules in the TGF-β1/JNK pathway. Results Sixteen patients were enrolled. There were 8 patients in the MR-AF group, including 5 males and 3 females, with an average age of (41.38±11.19) years; and 8 patients in the MS-AF group, including 6 males and 2 females, with an average age of (43.12±5.30) years. The left atrial volume load was higher in MR-AF patients, while the left atrial pressure load was higher in MS-AF patients. In MS-AF patients, the relative expression levels of MAPK9, JUN, CASP3, BAX, and BCL2 mRNA in left atrial tissues were significantly upregulated. The serum TGF-β1 protein level and the relative expression levels of p-JNK, p-c-Jun, and Caspase-3 proteins in the left atrial tissues of the MR-AF group were higher. Myocardial cell damage was more severe in the MS-AF group, and the protein expression level of Bcl-2 was higher. Conclusion Different MVD have distinct hemodynamic characteristics. The myocardium of the left atrium in MR-AF patients is more prone to apoptosis, possibly through the activation of the TGF-β1/JNK signaling pathway.

Objective To explore the imaging characteristics of lung cancers associated with cystic airspaces (LCCA) and the effects of different treatment regimens. Methods A retrospective analysis was conducted on the clinical and radiological data of LCCA patients who underwent surgical resection and pathological confirmation at the Department of Thoracic Surgery, the First Affiliated Hospital of Soochow University from 2016 to 2023. The relationship between various radiological classifications and clinical pathology was studied. Based on the postoperative adjuvant treatment follow-up results, the effects of different treatment regimens were analyzed. Results A total of 147 patients were included, including 90 males and 57 females, with a median age of 63 (55, 70) years. There were 21 patients of imaging typeⅠ, 50 patients of typeⅡ, 57 patients of type Ⅲ, and 19 patients of type Ⅳ. The lobulation sign or burr sign of typeⅠcyst walls (P=0.004), and intracystic septa (P=0.030) were more commonly seen in the high-aggressiveness group. The components of the cyst walls or nodules of types Ⅰ-Ⅳ in the high-aggressiveness group were mostly solid or sub-solid (P<0.05). Multivariate logistic regression analysis indicated that subsolid cyst wall (OR=4.734, P=0.023), solid cyst wall (OR=97.972, P<0.001), and the lobulation sign or burr sign of the cyst wall (OR=13.215, P=0.024) were independent risk factors for aggressiveness. Fifty-eight patients received adjuvant therapy after surgery, including 22 in the chemotherapy group, 15 in the targeted therapy group, and 21 in the combined therapy group. The progression-free survival of the combined therapy group was better than the other two groups (P=0.045). Conclusion There is a correlation between the imaging features of LCCA and pathological aggressiveness. Compared to postoperative targeted therapy or chemotherapy alone, postoperative chemotherapy combined with targeted therapy can improve the progression-free survival of LCCA patients.
7.Predictive accuracy of four scoring systems for cardiovascular complications during pregnancy in women with congenital heart disease: A systematic review and meta-analysis
Chinese Journal of Clinical Thoracic and Cardiovascular Surgery 2026;33(03):454-460
Objective To explore the predictive value of four risk scoring systems for cardiovascular complications during pregnancy in patients with congenital heart disease (CHD). Methods Computer searches were conducted in PubMed, EMbase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, and China Biology Medicine disc (CBM). Relevant studies on risk scoring systems for cardiovascular complications during pregnancy in CHD patients at home and abroad were comprehensively collected. The retrieval period was from the establishment of the databases to January 1, 2025, and the retrieval was updated on March 26, 2025. After two reviewers independently screened the literature and extracted the data, the quality assessment was carried out, and meta-analysis was performed using MedCalc software. Results A total of 11 studies were included, with a total of 4 987 patients. The incidence of cardiovascular complications during pregnancy in CHD patients ranged from 6.72% to 28.84%. The QUADAS-2 scoring tool results showed that 2 studies had unclear risk of bias, and 9 studies were determined to have a high risk of bias. The results of the meta-analysis showed that the CARPREGⅠ score [AUC=0.709, 95%CI (0.672, 0.745), P<0.001], CARPREGⅡ score [AUC=0.757, 95%CI (0.720, 0.794), P<0.001], ZAHARA score [AUC=0.732, 95%CI (0.674, 0.790), P<0.001], and mWHO classification system [AUC=0.681, 95%CI (0.617, 0.745), P<0.001] could independently predict cardiovascular complications during pregnancy in CHD patients. Conclusion The existing evidence indicates that all four scoring systems can be used to predict cardiovascular complications during pregnancy in CHD patients. Although the CARPREGⅡ score has the highest accuracy, the number of included studies is small. It is recommended to give priority to using the ZAHARA score for risk stratification and pregnancy management of women with CHD before pregnancy. In view of the limitations of the quality of the included studies, this study needs to be further confirmed by high-quality studies.

Objective:
To investigate whether Tuina alleviates fibrotic symptoms in myofascial trigger points (MTrPs) by regulating transforming growth factor (TGF)-β1/Smad3 signaling pathway, thereby deactivating these points.
Methods:
This study comprised two experimental phases. In phase 1, 27 specific pathogen-free (SPF) grade female Sprague-Dawley (SD) rats were randomized into three groups: control 1, model 1, and Tuina 1 groups. Model 1 and Tuina 1 groups underwent an 8-week MTrPs modeling protocol involving blunt impact and eccentric exercise. After successful modeling, rats in Tuina 1 group received manual pressing on nodules or cord-like taut bands on the medial aspect of the left hindlimb. Pain sensitivity and tissue stiffness were evaluated via pressure pain threshold (PPT) and soft tissue tension (STT). Muscle histopathology and fibrosis were observed using hematoxylin and eosin (HE) and Masson staining. Inflammatory factors in muscle were measured by enzyme-linked immunosorbent assay (ELISA), while immunofluorescence (IF) and Western blot (WB) were used to detect the expression levels of α-smooth muscle actin (α-SMA), collagen Ⅲ, and TGF-β1. In phase 2, 45 SPF female SD rats were randomized into five groups: control 2, model 2, Tuina 2, TGF-β1 inhibitor (TI), and Tuina + TGF-β1 agonist (Tuina + TA) groups. All groups except control 2 underwent standardized MTrPs modeling. Rats in Tuina 2 group received consistent pressing manipulation. TI group received intraperitoneal injections of oxymatrine, while Tuina + TA group received intraperitoneal injections of SRI-011381 hydrochloride followed by the same pressing protocol as Tuina 2 group. WB was used to detect the expression of collagen I, collagen III, TGF-β1, and phosphorylated-Smad3 (p-Smad3)/Smad3.
Results:
In phase 1, Tuina significantly improved PPT and STT in MTrPs of rats (P < 0.01), reversed pathological damages including disorganized muscle fiber arrangement, abnormal myocyte morphology, and exacerbated fibrosis. In addition, in MTrPs of rats in model 1 group, expression levels of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and fibrosis markers (α-SMA, collagen I, and collagen III) were upregulated, and all exhibited a significant downward trend after Tuina intervention (P < 0.05 or P < 0.01). This indicates that the therapeutic effects of Tuina are directly associated with reduced local inflammation and fibrosis in MTrPs. In phase 2, compared with model 2 group, rats in TI and Tuina 2 groups had decreased expression levels of TGF-β1 and p-Smad3/Smad3 in MTrPs, alongside reduced levels of inflammatory factors (IL-1β, IL-6, NF-κB, and TNF-α) and fibrosis markers (α-SMA, collagen I, and collagen III) (P < 0.05 or P < 0.01). When co-administered with TGF-β1 agonist, the therapeutic effects of Tuina were significantly attenuated, with rebounded TGF-β1 expression and p-Smad3/Smad3 in local MTrPs, and fibrosis and inflammatory responses were re-exacerbated (P < 0.05 or P < 0.01).
Conclusion
Tuina can effectively reduce inflammatory responses and fibrosis in MTrPs tissue, and its mechanism is closely related to the inhibition of the TGF-β1/Smad3 signaling pathway, which plays a critical role in Tuina-mediated regulation of MTrPs fibrosis.

Objective:
To explore the correlation of balance ability with short term memory and executive function among college students, so as to provide a theoretical basis for balance training and cognitive enhancement in college students.
Methods:
In November 2024, 80 college students were recruited from Chongqing Normal University. The dynamic and static balance abilities were measured using the Y-balance test(YBT) and PhysioSensing equipment. Short term memory and executive function were assessed through the digital span test, trail making test(TMT) and Stroop colour-word task. Pearson or Spearman analysis was used to explore the correlation between balance ability and cognitive function among college students.
Results:
The comprehensive scores of the balance YBT for college students were as follows: left side (95.14±5.93)% and right side (95.17±5.24)%.The average sway velocity of static balance under the conditions of stable surface with eyes open, stable surface with eyes closed, unstable surface with eyes open and unstable surface with eyes closed were 27.58(20.45, 37.64), 23.56(17.57, 34.77), 61.15(40.73, 78.05), 55.88 (40.84, 66.65)mm/s. The comprehensive scores of the YBT for both lower limbs in college students were negatively correlated with the time taken for TMT Part A (TMT-A), TMT Part B (TMT-B), and the difference in time spent between TMT-A and TMT-B (TMT-D) ( r =-0.55 to -0.24,all P <0.05). The average sway velocity under the four conditions was positively correlated with TMT-A, TMT-B, TMT-D, consistent reaction time, conflict reaction time and reaction time difference ( r =0.26-0.69,all P < 0.05). Under conditions of normal vestibular sensation with proprioception interference, the visual contribution in college students was negatively correlated with TMT-A, TMT-B, conflict reaction time and reaction time difference ( r =-0.28 to -0.22,all P < 0.05 ). Under conditions of normal vision and vestibular sensation, the proprioception contribution in college students was positively correlated with TMT-A, TMT-B, consistent reaction time, conflict reaction time and reaction time difference( r =0.26-0.39,all P < 0.05). Under conditions of normal vestibular sensation with visual interference, the proprioception contribution in college students was positively correlated with consistent reaction time and conflict reaction time ( r =0.24, 0.25,both P <0.05).
Conclusions
There is a correlation between balance ability and executive function in college students. When maintaining static balance, if the visual or proprioceptive system is interfered with, college students with poorer executive function rely more on other systems for compensation.
