Objective To investigate the reproductive and developmental effects of Clothianidin in rats. Methods Clothianidin was administrated by diet to both parental and first filial (F 1) generations of rats at the dosages of 0, 30.51, 110.84 and 304.26 mg/(kg·d) in females, and 0, 26.45, 92.69 and 279.42 mg/(kg·d) in males. Clothianidin was administered through diet to male and female rats for 8 weeks before mating. Clothianidin was administered to female rats in the parental and F1 generations during mating, gestation and lactation periods. During the test, toxicity performance was observed, reproduction index was calculated, and pathological examination was carried out. Results The body weights of rats in the parent and F1 generations in the high-dose group were lower than those in the control group during pre-mating exposure and at various time points during pregnancy and lactation (P<0.05). The pregnancy rates of parental and F1 generations in the high-dose group were lower than those of the control group (48.57% vs 71.43%, 45.71% vs 80.00%, P＜0. 05). Sperm concentration and sperm motility of the parental generation were lower than those of the control group [(42.55±12.87) vs (53.84±7.65) ×106/ml, (58.94±10.59) vs (65.59±6.03), （P＜0.05）]. Sperm concentration and sperm motility of the F1 generation were lower than those of the control group [(41.64±12.42) vs (53.09±9.48), (55.13±9.19) vs (64.53±6.31), (P＜0.05). Conclusion Exposure to clothianidin has reproductive toxicity to Wistar rats, and the no-observed adverse effect level (NOAEL) in the two-generation reproductive toxicity test is 92.69 mg/kg·BW for males and 110.84 mg/kg·BW for females in Wistar rats.

To analyze the treatment strategy for a 78-year-old female patient with mismatch repair deficient (dMMR) gastric cancer who achieved long-term survival. After third-line chemotherapy failed, gene testing showed ARID1A p.Gln748fs, c.2733-1G＞T variation, with PD-L1 TPS 30%, CPS 60%. The nivolumab was employed, and two weeks later, the best response was partial response (PR). During the fourth-line immunotherapy maintenance treatment, progression of left adrenal metastasis was observed. The expression of human epidermal growth factor receptor-2 (HER-2) was positive, and the antibody drug conjugate disitamab vedotin (RC48) was chosen for treatment. After 10 months of treatment with nivolumab combined with RC48, the best efficacy was assessed as stable disease (SD), with a progression free survival (PFS) of up to 12 months. Radiotherapy was employed, and immunotherapy was maintained, allowing the patient to achieve a PFS of 18 months again. During immunotherapy, a clinical pharmacist developed a personalized pharmaceutical care plan for this patient. At the last follow-up, this patient achieved 78 months of long-term survival.

BACKGROUND: Durvalumab after chemoradiotherapy (CRT) failed to bring survival benefits to patients with epidermal growth factor receptor ( EGFR ) mutations in PACIFIC study (evaluating durvalumab in patients with stage III, unresectable NSCLC who did not have disease progression after concurrent chemoradiotherapy). We aimed to explore whether locally advanced inoperable patients with EGFR mutations benefit from tyrosine kinase inhibitors (TKIs) and the optimal treatment regimen. METHODS: We searched the PubMed, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases from inception to December 31, 2022 and performed a meta-analysis based on a Bayesian framework, with progression-free survival (PFS) and overall survival (OS) as the primary endpoints. RESULTS: A total of 1156 patients were identified in 16 studies that included 6 treatment measures, including CRT, CRT followed by durvalumab (CRT-Durva), TKI monotherapy, radiotherapy combined with TKI (RT-TKI), CRT combined with TKI (CRT-TKI), and TKI combined with durvalumab (TKI-Durva). The PFS of patients treated with TKI-containing regimens was significantly longer than that of patients treated with TKI-free regimens (hazard ratio [HR] = 0.37, 95% confidence interval [CI], 0.20-0.66). The PFS of TKI monotherapy was significantly longer than that of CRT (HR = 0.66, 95% CI, 0.50-0.87) but shorter than RT-TKI (HR = 1.78, 95% CI, 1.17-2.67). Furthermore, the PFS of RT-TKI or CRT-TKI were both significantly longer than that of CRT or CRT-Durva. RT-TKI ranked first in the Bayesian ranking, with the longest OS (60.8 months, 95% CI = 37.2-84.3 months) and the longest PFS (21.5 months, 95% CI, 15.4-27.5 months) in integrated analysis. CONCLUSIONS: For unresectable stage III EGFR mutant NSCLC, RT and TKI are both essential. Based on the current evidence, RT-TKI brings a superior survival advantage, while CRT-TKI needs further estimation. Large randomized clinical trials are urgently needed to explore the appropriate application sequences of TKI, radiotherapy, and chemotherapy.

This study predicts the quality markers(Q-markers) for the cough-relieving and phlegm-expelling effects of Kening Granules based on pharmacodynamics, plasma drug chemistry, network pharmacology, and pharmacokinetics. Strong ammonia solution spray and phenol red secretion assays were employed to evaluate the cough-relieving and phlegm-expelling effects of Kening Granules. Twentysix absorbed prototype components of Kening Granules were identified by ultra high performance liquid chromatography coupled with QExactive Plus quadrupole/Orbitrap high resolution mass spectrometry(UHPLC-Q-Exactive Plus Orbitrap HRMS). Through network pharmacology, 11 potential active components were screened out for the cough-relieving and phlegm-expelling effects of Kening Granules. The 11 components acted on 40 common targets such as IL6, TLR4, and STAT3, which mainly participated in PI3K/Akt, HIF-1, and EGFR signaling pathways. Pharmacokinetic quantitative analysis was performed for 7 prototype components. Three compounds including azelaic acid, caffeic acid, and vanillin were identified as Q-markers for the cough-relieving and phlegm-expelling effects of Kening Granules based on their effectiveness, transmissibility, and measurability. The results of this study are of great significance for clarifying the pharmacological substance basis, optimizing the quality standards, and promoting the clinical application of Kening Granules.

OBJECTIVES: To explore the impact of different treatment attitudes on the survival status of extremely preterm infants (EPIs) and evaluate the mortality and occurrence of severe complications in actively treated infants, as well as their risk factors. METHODS: A retrospective analysis was conducted on perinatal data of EPIs born between January 1, 2016, and December 31, 2023, who were admitted to the neonatal intensive care unit of Nanjing Women and Children's Healthcare Hospital within 24 hours after birth. The analysis focused on the attributable risk of mortality associated with different treatment attitudes in EPIs of varying gestational ages and birth weights. A multivariate logistic regression model was used to analyze the risk factors for mortality and severe complications in the actively treated group. RESULTS: A total of 485 EPIs were included. As gestational age or birth weight increased, the attributable risk of mortality with care withdrawal increased. Active treatment significantly improved the survival status of EPIs born at a gestational age of ≥24 weeks. Multivariate logistic regression analysis indicated that lower gestational age and the need for mechanical ventilation within 72 hours after birth were independent risk factors for mortality or severe complications in EPIs (P<0.05). CONCLUSIONS Active treatment can significantly extend the survival time of EPIs born at a gestational age of ≥24 weeks. Lower gestational age and the need for mechanical ventilation within 72 hours after birth are closely associated with poor survival outcomes in EPIs.

Objective:To explore the correlation between serum hepcidin antimicrobial peptide (HAMP), secreted phosphoprotein 1 (SPP1), and regulator of G protein signaling 2 (RGS2) levels and the clinical pathological characteristics of gastric cancer patients, and their predictive value for postoperative recurrence or metastasis.Methods:A total of 92 gastric cancer patients treated at Handan First Hospital from March 2021 to March 2023 were selected as the gastric cancer group, and 92 healthy individuals who underwent physical examinations during the same period were selected as the control group. The serum levels of HAMP, SPP1 and RGS2 were compared between the two groups. According to the mean levels of HAMP, SPP1, and RGS2 in the serum of gastric cancer patients, they were divided into HAMP high level group and HAMP low level group, SPP1 high level group and SPP1 low level group, RGS2 high level group and RGS2 low level group. The clinicopathological characteristics of gastric cancer patients with different levels of HAMP, SPP1 and RGS2 were compared respectively. After a median follow-up of 18 months, gastric cancer patients were divided into a non-recurrence or metastasis group ( n=59) and a recurrence and metastasis group ( n=33) based on whether the tumor recurred or metastasized. The serum levels of HAMP, SPP1, and RGS2 were compared between the two groups of patients. The predictive value of HAMP, SPP1 and RGS2 for postoperative recurrence or metastasis in patients with gastric cancer was analyzed by using the receiver operator characteristic (ROC) curve. Results:Compared with the control group, the gastric cancer group had higher levels of serum HAMP [ (52.28±5.44) ng/ml vs. (31.22±4.18) ng/ml] and SPP1 [ (55.96±6.43) ng/ml vs. (36.99±5.25) ng/ml] ( t=29.44, P<0.001; t=21.92, P<0.001), and lower level of RGS2 [ (3.72±0.66) mg/L vs. (5.11±0.87) mg/L) ] ( t=12.21, P<0.001). There were statistically significant differences in maximum tumor diameter ( χ2=13.07, P<0.001; χ2=6.71, P=0.010; χ2=10.56, P=0.001), TNM staging ( χ2=7.42, P=0.006; χ2=6.36, P=0.012; χ2=5.39, P=0.020), lymph node metastasis ( χ2=23.41, P<0.001; χ2=6.52, P=0.011; χ2=13.11, P<0.001), and differentiation degree ( χ2=9.01, P=0.003; χ2=7.97, P=0.005; χ2=15.29, P<0.001) between the gastric cancer patients in the HAMP high level group ( n=44) and the HAMP low level group ( n=48), the SPP1 high level group ( n=43) and the SPP1 low level group ( n=49), and the RGS2 high level group ( n=50) and the RGS2 low level group ( n=42). Compared with the non-recurrence or metastatic group, the recurrence and metastatic group had higher levels of serum HAMP [ (59.26±5.66) ng/ml vs. (48.37±4.28) ng/ml] and SPP1 [ (62.85±6.36) ng/ml vs. (52.11±5.38) ng/ml] level ( t=10.40, P<0.001; t=8.60, P<0.001), and lower level of RGS2 [ (3.01±0.48) mg/L vs. (4.12±0.69) mg/L] ( t=8.19, P<0.001). ROC curve analysis showed that the area under the curve (AUC) values of serum HAMP, SPP1, and RGS2 levels alone for predicting postoperative recurrence or metastasis in gastric cancer patients were 0.777, 0.813, and 0.778, respectively. The AUC value of the combination of the three indicators for predicting postoperative recurrence or metastasis in gastric cancer patients was 0.871. The predictive efficacy of the combination of the three indicators for predicting postoperative recurrence or metastasis in gastric cancer patients was better than that alone ( Z=2.51, P=0.035; Z=2.61, P=0.032; Z=2.71, P=0.029) . Conclusions:The levels of HAMP and SPP1 in the serum of gastric cancer patients increase, while the level of RGS2 decreases, and the levels of the three are related to the maximum tumor diameter, TNM staging, lymph node metastasis and differentiation degree, and their combined detection has higher predictive value for postoperative recurrence or metastasis in gastric cancer patients.

Objective To investigate the relationship between kinase insert domain receptor(KDR)rs2305948 polymorphism and clopidogrel resistance(CR)in patients with acute coronary syndrome after receiving percutaneous coronary intervention(PCI).Methods A total of 468 patients with acute coronary syndrome,who were admitted to the Zhangjiakou Municipal First Hospital of China from September 2022 to September 2023,were selected as the subjects of study.All patients received PCI treatment and took medication of clopidogrel after the treatment.The occurrence of CR was recorded.The factors influencing the occurrence of CR were analyzed.The clinical significance of KDR rs2305948 polymorphism in predicting CR in patients with acute coronary syndrome after receiving PCI was evaluated.Results Of 468 patients with acute coronary syndrome,116(24.79％)developed CR.Logistic multivariate regression analysis indicated that low-density lipoprotein cholesterol(LDL-C,95％CI=1.420-8.390,OR=3.452),type 2 vascular endothelial growth factor receptor(VEGFR-2,95％CI=1.374-8.118,OR=3.340),KDR rs2305948 T/T genotype(95％CI=1.677-9.905,OR=4.076),and T allele(95％CI=1.390-8.207,OR=3.377)were the independent factors influencing the occurrence of CR inpatients with acute coronary syndrome after receiving PCI(all P＜0.05).Receiver operating characteristic(ROC)curve analysis showed that the sensitivity,specificity,and area under ROC curve(AUC)of the T/T genotype of KDR rs2305948 in predicting CR in patients with acute coronary syndrome after receiving PCI were 75.86％,70.45％,and 0.773(95％CI=0.666-0.880)respectively.Conclusion In patients with acute coronary syndrome after receiving PCI,the risk of developing CR is higher.The KDR rs2305948 polymorphism is correlated with CR in patients with acute coronary syndrome after receiving PCI,and it has a certain predictive value for CR.

Objective To investigate the genetic causal relationship between rheumatoid arthritis (RA) and its serological antibody levels with pre-eclampsia (PE) based on Mendelian randomization (MR). Methods Single nucleotide polymorphism (SNP) with significant differences were screened as instrumental variables,and the five MR analytic method with the inverse variance weighting (IVW) as the main analytical method were applied to comprehensively assess the causal cc relationship between OA,serum antibody levels PE.The MR-Egger intercept method,MR pleiotropy residual and outlier (MR-PRESSO) method,Cochrane's Q-test were applied to explore the horizontal pleiotropy and heterogeneity of SNP,and the leave-one-out meth-od was used to explore the effect of individual SNPs on MR results.Results The IVW result indicated that RA (OR=1.098,95％CI:1.036-1.164,P=0.002) and seropositive RA (OR=1.088,95％CI:1.026-1.153,P=0.005) were the PE risk factors,whereas seronegative RA (OR=1.036,95％CI:0.971-1.104, P=0.282) did not have a significant causal relationship with PE.No significant level pleiotropy or heteroge-neity was found in the SNPs used in MR analyses of the 3 exposure factors.rs34434863 played a decisive role in the causal relationship of RA and seropositive RA with PE.Conclusion Based on MR analysis,there is a significant positive causal relationship between RA and seropositive RA with PE,whereas there was no signifi-cant causal relationship between seronegative RA and PE.

"Symptoms such as syncope, constipation or incontinence all belong to the lower part" comes from Bing Ji Shi Jiu Tiao ( Su Wen Zhi Zhen Yao Da Lun). Doctors mostly recognize the meaning of this pathogenesis from macroscopic symptoms. From a microscopic point of view, proteinuria and increased SCr are the most common clinical manifestations of most kidney diseases, which can be classified into the categories of "incontinence" and "constipation" respectively. The meaning of "lower" is mostly thought to refer to or include kidney. Therefore, microscopic detection methods can be used in clinical practice. The pathogenesis of many kinds of kidney diseases can be explored based on the changes of kidney microstructure combined with the theory of TCM to establish a diagnosis and treatment system of microscopic TCM syndrome differentiation and differentiate and treat nephropathy by combining micro and macro evidence.

Objective To observe the therapeutic effect and mechanism of Shentong Zhuyu Granules on rheumatoid arthritis(RA)rats.Methods There were 12 rats randomly selected from 60 rats as the normal group,and the remaining 48 rats were gaven two immunization in the simulated environment of'wind,cold and dampness'to construct the RA model.All 48 successfully modeled rats were randomly divided into model group,Shentong Zhuyu Granules high-,medium-and low-dose groups,with 12 rats in each group.All the groups were given corresponding administration for 21 days.Hematoxylin-eosin(HE)staining was used to observe and score the histopathology of synovial membrane of ankle joint in rats after administration.The swelling degree of bilateral ankle joints and feet of rats was compared before and after administration.Enzyme-linked immunosorbent assay(ELISA)was used to detect the contents of inflammatory factors tumor necrosis factor(TNF)-α,interleukin(IL)-1β,IL-6 and interferon(IFN)-γ in ankle joint synovial tissue of rats after administration.The protein expressions of Janus kinase(JAK)/signal transducer and activator of transcription(STAT)pathway in synovial tissues of rats were detected by Western Blot.Results Compared with the normal group,the synovial membrane of the rats in the model group proliferated,the structure of chondrocytes was disordered,and a large number of inflammatory cells infiltrated in the cartilage cavity,the scores of inflammatory cell infiltration and bone destruction were significantly increased(P＜0.05),the swelling degree of bilateral ankle joints and feet was increased(P＜0.05),the contents of TNF-α,IL-1β,IL-6 and IFN-γ in the synovial tissue,and the protein expression levels of JAK1,STAT3,phosphorylated STAT3(p-STAT3),STAT5 and phosphorylated STAT5(p-STAT5)were significantly increased(P＜0.05).Compared with the model group,the above indexes in the high-,medium-and low-dose groups of Shentong Zhuyu Granules were significantly improved(P＜0.05).Conclusion Shentong Zhuyu Granules can effectively improve RA in rats,and its mechanism is related to the inhibition of inflammatory factors and the activation of JAK/STAT signaling pathway.
