Lung cancer is the malignant tumor with the highest incidence and mortality rates globally. Current treatment methods for lung cancer primarily include surgery, chemotherapy, targeted therapy, and immunotherapy. However, the main limitations of these treatments are their side effects, the drug resistance, and the economic burden they impose. As a critical cancer pathway, the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathway regulates tumor occurrence and development through multiple mechanisms by influencing various downstream targets. Consequently, the JAK/STAT signaling pathway offers a promising avenue for lung cancer treatment research. Numerous studies have demonstrated that the JAK/STAT signaling pathway plays a key role in the proliferation and growth of lung cancer cells, angiogenesis, epithelial-mesenchymal transition (EMT), metabolic alterations, remodeling of the immune microenvironment, and the development of treatment resistance. Traditional Chinese medicine (TCM) has garnered increasing attention due to its minimal side effects, low economic burden, and its potential to enhance efficacy and reduce toxicity when used in conjunction with Western medicine. In addition to traditional Chinese medicine compounds, a growing number of Chinese medicine monomers have come into the spotlight because of their more targeted effects. Numerous studies investigating the regulation of the JAK/STAT signaling pathway by TCM in the treatment of lung cancer have demonstrated that TCM can inhibit the proliferation and invasion of lung cancer cells, tumor angiogenesis, and EMT, improve the inflammatory and immunosuppressive microenvironments, and enhance treatment sensitivity by intervening in the JAK/STAT signaling pathway, thereby impeding the progression of lung cancer. In recent years, the research on the regulation of this pathway by TCM in the treatment of lung cancer has been updated rapidly. However, the summary of these studies has not been updated in time. This review summarizes and reflects on the recent research findings regarding the regulation of the JAK/STAT signaling pathway by TCM to intervene in lung cancer from three aspects, introducing the JAK/STAT pathway, elaborating the mechanism of this pathway in lung cancer, and exploring the intervention of TCM in the treatment of lung cancer through this pathway, to provide more reference for the treatment of lung cancer in the future.

OBJECTIVE To explore the effect and mechanism of Prunus mume against hepatic fibrosis (HF). METHODS Male SD rats were randomly divided into normal control group (n=10) and modeling group (n=50). The modeling group established HF model using carbon tetrachloride. The modeled rats were randomly divided into model group (normal saline), positive control group [colchicine, 0.09 mg/(kg·d)], and P. mume low-dose, medium-dose and high-dose groups [1.35, 2.70, 5.40 g/(kg·d)], with 9 rats in each group. They were given the corresponding drug/normal saline intragastrically, once a day, for 8 consecutive weeks. After the last medication, the liver index was calculated, while liver function indexes, liver fiber indexes, oxidative stress indicators and inflammatory factors of rats were measured. HE staining was used to observe the pathological changes in liver tissue of rats; Masson staining was used to observe the degree of HF in liver tissue of rats; transmission electron microscopy was used to observe the ultrastructure of liver tissue in rats; TUNEL staining was used to detect liver cell apoptosis in each group of rats. Western blot method was used to detect the protein expressions of transforming growth factor-β1 (TGF-β1) and platelet-derived growth factor (PDGF) in liver tissue of rats. RESULTS Compared with normal control group, the levels of alanine transaminase, alkaline phosphatase, aspartate transaminase, total bilirubin, malondialdehyde, procollagen type Ⅲ protein, Ⅳ-type pre collagenase, laminin, hyaluronic acid, interleukin-6, tumor necrosis factor-α, as well as the protein expressions of TGF-β1 and PDGF in model group were increased significantly, while the levels of superoxide dismutase and glutathione peroxidase were significantly reduced (P<0.01); the HE, Masson staining and transmission electron microscopy observation results showed obvious HF characteristics in rats of model group. Compared with model group, varying degrees of improvement in above indexes were observed in P. mume groups, and the above 2021BSZR011) indicators of rats in P. mume medium-dose and high-dose groups were reversed significantly (P<0.05 or P<0.01). CONCLUSIONS P. mume has an anti-HF effect, which may be achieved through mechanisms such as antioxidation, anti-inflammation, reduction of collagen production, inhibition of PDGF protein expression, and regulation of TGF- β1 signaling pathway.

ObjectiveTo explore the incremental cost of central line-associated bloodstream infections (CLABSI) after central venous catheterization (CVC) in critically ill patients in the intensive care unit (ICU), as well as the main cost of nosocomial infection prevention and control. By comparing these two costs, the medical personnel to pay more attention should CLABSI prevention and control from the perspectives of medical quality and economic benefits, and promote the implementation of prevention and control measures. MethodsCluster sampling was used to select 126 critically ill patients who underwent CVC in the ICU of a tertiary traditional Chinese medicine hospital from January 2021 to December 2023, including 65 cases in the CLABSI group and 61 in the non-CLABSI group. Patients’ data were retrospectively collected from the hospital medical records, including the disease type, gender, age, length of hospital stay, outcome, and hospitalization expenses. The costs of different hand hygiene methods and differing approaches to environmental cleaning and disinfection were analyzed and compared. ResultsThere were significant differences in the length of hospital stay (Z=-5.35, P<0.05) and total hospitalization expenses (Z=-6.79, P<0.05) between the CLABSI and non-CLABSI group. Total hospitalization expenses showed significant differences among patients with different lengths of hospital stay (H=43.01, P<0.05), with much higher median one in those with 60 or more days of hospital stay than other patients. Greater differences of median total hospitalization expenses were found in males than in females (Z=-3.98, P<0.05), as well as in patients aged 60-80 years than in patients of other ages (Z=-5.79, P<0.05). ConclusionsThe occurrence of CLABSI significantly increases the ICU patients’ length of hospital stay and hospitalization expenses. There are differences in the costs of different hand hygiene methods and differing approaches to environmental cleaning and disinfection, but these costs are acceptable compared to the incremental costs directly attributable to CLABSI. Therefore, medical institutions should attach importance to the investment in prevention and control of nosocomial infections such as hand hygiene and environmental cleaning and disinfection, formulate practical, reasonable and feasible plans, and ensure their implementation, in order to avoid nosocomial infections, improve the medical quality, effectively control patients’ length of hospital stay and hospitalization costs, and strive to maintain patient safety.

The liver, skeletal muscle, and adipose tissue are central energy-metabolizing organs and insulin-sensitive tissues, playing a crucial role in maintaining glucose homeostasis. As the powerhouse of the cell, mitochondria not only regulate insulin secretion but also oversee the oxidative phosphorylation and β-oxidation of fatty acids, processes vital for the metabolism of carbohydrates and fats, as well as the synthesis of ATP. The mitochondrial quality control system is of paramount importance for sustaining mitochondrial homeostasis, achieved through mechanisms such as protein homeostasis, mitochondrial dynamics, mitophagy, and biogenesis. Evidence suggests that dysfunctional mitochondria may significantly contribute to insulin resistance and ectopic fat storage in the liver, offering new insights into the strong correlation between mitochondrial dysfunction and the development of obesity, diabetes mellitus type 2 (T2DM), and non-alcoholic fatty liver disease (NAFLD). This manuscript aims to delve into the precise mechanisms by which imbalances in mitochondrial quality control lead to metabolic disorders in the liver, skeletal muscle, and adipose tissue, the 3 major insulin-sensitive organs. In the liver, mitochondrial dysfunction can lead to disturbances in glucose and lipid metabolism, resulting in insulin resistance and fat accumulation—a key factor in the development of NAFLD. In skeletal muscle, reduced mitochondrial function can decrease ATP production, weakening the muscle’s ability to uptake glucose, thereby exacerbating insulin resistance. In adipose tissue, mitochondrial dysfunction can impair adipocyte function, leading to lipotoxicity and inflammatory responses,which further contribute to insulin resistance and the onset of metabolic syndrome. Moreover, the interorgan crosstalk among these 3 tissues is essential for overall metabolic homeostasis. For instance, hepatic gluconeogenesis and glucose utilization in skeletal muscle are both influenced by the health status of their respective mitochondrial populations. The conversion between different types of adipose tissue and the ability to store lipids depend on normal mitochondrial function to avert ectopic fat accumulation in other organs. In summary, this manuscript emphasizes the critical role of mitochondrial quality control in maintaining the metabolic stability of the liver, skeletal muscle, and adipose tissue. It elucidates the specific mechanisms by which mitochondrial dysfunction in these organs contributes to the development of metabolic diseases, providing a foundation for future research and the development of therapeutic strategies targeting mitochondrial dysfunction.

Objective To investigate the long-term safety and effectiveness of withdrawal of hepatitis B immuneglobulin (HBIG) and/or nucleos(t)ide analogues (NAs) to prevent hepatitis B virus (HBV) reinfection in liver transplant recipients with hepatitis B-related diseases after successful vaccination. Methods Baseline data of 76 liver transplant recipients undergoing hepatitis B immune reconstitution after receiving hepatitis B vaccines were retrospectively analyzed. The vaccination and response, the follow-up results of respondents with HBIG and/or NAs withdrawal, and the reinfection of HBV after withdrawal of HBIG and/or NAs were analyzed. Results The time interval from liver transplantation to hepatitis B vaccination was 26 (20, 40) months. The time interval from vaccination to response was 15 (8,27) months. Initially, 76 recipients withdrew HBIG, and 36 recipients withdrew HBIG and NAs. During the follow-up, 12 of 76 recipients who withdrew HBIG resumed use of HBIG, and 16 of 36 recipients who withdrew HBIG and NAs resumed use of NAs. The withdrawal time of HBIG and NAs was 135 (98,150) and 133 (34,149) months, respectively. Sixteen respondents did not receive booster, and 36 respondents received boosters on a regular basis. The time interval between the first booster and HBIG withdrawal was 44 (11,87) months. No significant differences were observed in baseline data between the respondents with and without boosters (all P>0.05). During the follow-up, 9 recipients were lost to follow-up, 5 were re-infected with HBV, 3 died, and 1 recipient developed graft loss and underwent secondary liver transplantation. Among 5 recipients re-infected with HBV, 4 cases had virus mutation. Significant differences were found between re-infected and uninfected patients regarding withdrawal of NAs and hepatitis B e antigen (HBeAg) positive before transplantation (both P<0.05). Conclusions Long-term withdrawal of HBIG is feasible and safe for recipients with successful hepatitis B immune reconstitution after liver transplantation for hepatitis B-related diseases. Nevertheless, whether antiviral drugs can be simultaneously withdrawn remains to be validated.

【Objective】 To compare the effects of 3 rehydration methods before blood donation on the prevention of on-site and delayed blood donation-related vasovagal response (VVR) . 【Methods】 From January to June 2021, 6 250 whole blood donors in 6 fixed blood donation sites signed informed consent and were divided into 198 clusters according to donor sites and dates, then they were randomly assigned to receive either oral rehydration salts (ORS), sugar water, or water group, and each drank 500 mL of ORS, sugar water or water within 20 minutes before blood donation. The researchers recorded the actual intervention accepted on site, and recorded the immediate VVR and related information. At rest after blood donation, donors submitted an electronic questionnaire containing socio-demographic information. At 48 hours after blood donation, the researchers called back every donor to record delayed VVR and related information. Logistic regression based on intention to treat (ITT) was used to analyze the difference of the incidence of VVR among the three groups, and the average treatment effect on treated (ATT) was calculated. PASS 2021was used to estimate the sample size and R (4.2.0) for statistical analysis. 【Results】 The cumulative incidence of blood donation-related VVR was 2.67% (2.29%-3.11%) among street whole blood donors under the 3 rehydration methods, in which, the incidence of immediate and delayed VVR was 1.02% (0.79%-1.31%) and 1.65% (1.36%-2.01%) respectively. ITT analysis found that ORS were more effective than water in reducing the incidence of delayed VVR【OR=0.59,95% CI[0.37,0.94]】.There was no significant difference in the incidence of immediate VVR between any two groups (P > 0.05), and there was no significant difference in the incidence of delayed VVR in the sugar water group compared with the water group (P > 0.05). There was a difference of -0.013 (【95% CI[-0.022, -0.004]】or -0.008【95% CI[-0.017, -0.000]】in the incidence of delayed VVR in the ORS group compared with water group or sugar water group, the difference was significant (P<0.05). The cumulative VVR of the three groups showed similar results to the delayed VVR. 【Conclusion】 Drinking ORS before blood donation is the most effective rehydration method to prevent delayed VVR. The next step is to establish the predictive model of delayed VVR to screen the susceptible population and provide them with ORS before blood donation, while other population can choose any liquid they like, thus achieving personalized blood donation-related VVR prevention and control.

Objective To investigate the dosimetric difference between manual and inverse optimization in 3-dimensional (3D) brachytherapy for gynecologic tumors. Methods This retrospective study was conducted among a total of 110 patients with gynecologic tumors undergoing intracavitary combined with interstitial brachytherapy or interstitial brachytherapy. Based on the original images, the brachytherapy plans were optimized for each patient using Gro, IPSA1, IPSA2 (with increased volumetric dose limits on the basis of IPSA1) and HIPO algorithms. The dose-volume histogram (DVH) parameters of the clinical target volume (CTV) including V200, V150, V100, D90, D98 and CI, and the dosimetric parameters D2cc, D1cc, and D0.1cc for the bladder, rectum, and sigmoid colon were compared among the 4 plans. Results Among the 4 plans, Gro optimization took the longest time, followed by HIPO, IPSA2 and IPSA1 optimization. The mean D90, D98, and V100 of HIPO plans were significantly higher than those of Gro and IPSA plans, and D90 and V100 of IPSA1, IPSA2 and HIPO plans were higher than those of Gro plans (P<0.05), but the CI of the 4 plans were similar (P>0.05). For the organs at risk (OARs), the HIPO plan had the lowest D2cc of the bladder and rectum;the bladder absorbed dose of Gro plans were significantly greater than those of IPSA1 and HIPO (P<0.05). The D2cc and D1cc of the rectum in IPSA1, IPSA2 and HIPO plans were better than Gro (P<0.05). The D2cc and D1cc of the sigmoid colon did not differ significantly among the 4 plans. Conclusion Among the 4 algorithms, the HIPO algorithm can better improve dose coverage of the target and lower the radiation dose of the OARs, and is thus recommended for the initial plan optimization. Clinically, the combination of manual optimization can achieve more individualized dose distribution of the plan.
