Based on the long bud stage phenotype of a new Lonicera japonica Flos variety "Huajin 6", using "Huajin 6" and "Da Mao Hua" as materials, probing the mechanism of its phenotype formation. Detection of endogenous Jasmonic acid hormones (JAs) content; the genes related to jasmonic acid (JA) synthesis were identified by transcriptome analysis of Lonicera japonica; flower buds and flowers of "Huajin 6" and "Da Mao Hua" were collected at different periods, and the qRT-PCR (quantitative real-time PCR) technique was used to analyze the trend of the expression of synthesis-related enzyme genes in Lonicera japonica Flos during the bud stage. The study found that the content of JAs in "Huajin 6" Lonicera japonica Flos was significantly lower than that in "Da Mao Hua"; applying exogenous methyl-jasmonate (MeJA) to "Huajin 6" can restore its flowering phenotype, making it close to wild type Lonicera japonica Flos; there are significant differences in the expression of two allene oxide synthase genes (AOS), three lipoxygenase genes (LOX), and two allene oxide cyclase genes (AOC) in the flowers and buds of "Huajin 6" and "Da Mao Hua" at different periods. It is hypothesized that the low expression of JA synthesis-related enzyme genes in " Huajin 6" leads to the blockage of JA synthesis, which causes the formation of the long bud phenotype. This study laid a certain foundation for the genetic breeding of Lonicera japonica, provided a new idea for the improvement of Lonicera japonica varieties, and provided a reference for the study of JAs in plant flower organs.

Objective To evaluate the clinical efficacy of Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate plus traditional Chinese medicine(TCM)bone-setting manipulations for the treatment of moderate hallux valgus.Methods A retrospective study was conducted.A total of 49 patients(62 feet)with moderate hallux valgus were treated with Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate,and were given TCM bone-setting manipulations before the operation,during the operation,and after the operation.The efficacy was evaluated by using the Visual Analogue Scale(VAS)score and the American Orthopedic Foot and Ankle Society(AOFAS)forefoot score after the operation.Before the operation and 12 months after the operation,the hallux valgus angle(HVA),intermetatarsal angle(IMA)between the first and second metatarsal bone,and the distal metatarsal articular angle(DMAA)showed by X-ray imaging in the weight-bearing position of the foot were recorded.Results(1)All of the 49 patients were followed up for 12 to 24 months,with a mean of(20.6±3.1)months.(2)The X-ray imaging assessment showed that 12 months after the operation,the mean HVA,IMA and DMAA values of the 49 patients(62 feet)were significantly lower than those before the operation,and the differences were all statistically significant(P＜0.01).(3)Twelve months after the operation,the pain VAS score of 49 patients was(3.14±1.21)points,which was significantly lower than the preoperative score points(7.26±2.52),and the difference was statistically significant(P＜0.01).(4)The assessment of joint function showed that 12 months after the operation,the scores of various AOFAS items of pain,function and hallux alignment as well as the overall AOFAS scores of 49 patients were significantly higher than those before the operation,and the differences were statistically significant(P＜0.01).(5)For the 62 feet in 49 patients,the excellent efficacy was achieved in 53 feet,good efficacy was achieved in 7 feet,and fair efficacy was achieved in 2 feet,with the fine rate of 96.77%(60/62).Conclusion For the treatment of moderate hallux valgus,the application of Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate plus TCM bone-setting manipulations is effective on promoting the reset of hallux-metatarsophalangeal joint,restoring the balance of the joint,and maintaining the equilibrium state of the joint through postoperative rehabilitation guidance.The combined therapy exerts certain efficacy,reduces the recurrence rate,and eventually achieves the early rehabilitation after the operation.

Objective To systematically evaluate the effect and safety of neoadjuvant PD-1/PD-L1 inhibitors combined with chemotherapy for resectable non-small cell lung cancer (NSCLC). Methods The PubMed, EMbase, The Cochrane Library, CNKI, and Wanfang data were searched by computer to identify relevant studies on anti PD-1 /PD-L1 combined with chemotherapy for resectable NSCLC from inception to March 2023. Two authors independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies. The single-arm study was evaluated for quality using the methodological index for non-randomized studies (MINORS). Meta-analysis was conducted by RevMan 5.4 software. Results Twenty-six studies with 965 patients were included in this meta-analysis. MINORS scores of single-arm studies were ≥12 points. The meta-analysis results showed that the pooled pathologic complete response, major pathologic response, and objective response rates as well as partial response, surgical rate and R0 surgical resection rate of neoadjuvant PD-1/PD-L1 inhibitors combined with chemotherapy were 39% [RD=0.39, 95%CI (0.31, 0.47) ], 59% [RD=0.59, 95%CI (0.53, 0.65) ], 72% [RD=0.72, 95%CI (0.65, 0.80) ], 62% [RD=0.62, 95%CI (0.56, 0.69) ], 86% [RD=0.86, 95%CI (0.81, 0.92) ], and 94% [RD=0.94, 95%CI (0.92, 0.97) ], respectively. In terms of safety, the rate of adverse events (AEs) was 65% [RD=0.65, 95%CI (0.52, 0.78) ], and the rate of grade 3 to 5 AEs was 16% [RD=0.16, 95%CI (0.10, 0.23) ]. Conclusion The combination of neoadjuvant PD-1/PD-L1 inhibitors with chemotherapy has good efficacy and safety in the treatment of patients with resectable NSCLC.

This paper applied gas chromatography-mass spectrometry (GC-MS), network pharmacology and nuclear magnetic resonance hydrogen spectroscopy (¹H NMR) metabolomics techniques to study the material basis and mechanism of action of Ning Shen Essential Oil in anti-insomnia. The main volatile components of Ning Shen Essential Oil were analyzed by gas chromatography-mass spectrometry (GC-MS), and the insomnia-related targets were predicted using the Traditional Chinese Medicine Systematic Pharmacology Database and Analytical Platform (TCMSP) and the databases of GeneCards, OMIM and Drugbank. The insomnia model of rats was replicated by intraperitoneal injection of 4-chloro-DL-phenylalanine (PCPA). Animal experiments were approved by the Animal Ethics Committee of Shandong University of Traditional Chinese Medicine (Ethics No.: SDUTCM20221025010). The modulating effect of Compound Ning Shen Essential Oil on anxiety behavior of rats was evaluated by behavioral related indexes. The serum levels of corticotropin-releasing hormone (CRH), adrenotropic corticotropic hormone (ACTH) and melatonin (MT) were measured by enzyme-linked immunoassay (ELISA). Rat serum and hippocampus were taken for nuclear magnetic resonance (¹H NMR) metabolomics to detect the changes of endogenous metabolites in rat serum hippocampus, to designate the differential metabolites and to construct metabolic pathways. The results showed that the exercise distance in the open field experiment and the number of times and time to enter the open arm in the elevated cross maze experiment of the rats in the model group were significantly reduced (P < 0.05, P < 0.01). The behavioral indexes of rats improved to different degrees after the administration of Ning Shen Essential Oil. The serum CRH and ACTH levels of rats in the model group increased significantly (P < 0.05, P < 0.01), and the MT level decreased significantly (P < 0.01); After the intervention, serum CRH and ACTH levels were reduced to different degrees, and MT levels could be regressed. ¹H NMR metabolomics screened 10 potential biomarkers related to insomnia, which involved in 6 potential metabolic pathways. A total of 35 components of Ning Shen Essential Oil were detected by GC-MS, the main component targets of Ning Shen Essential Oil and insomnia disease targets were intersected, a total of 172 intersecting genes were screened, and 26 core targets were identified. The study demonstrated that Ning Shen Essential Oil had protective effects against PCPA-induced insomnia in rats, which was probably correlated with regulation of the hypothalamic-pituitary-adrenal axis (HPA) related hormones and metabolism of amino acids, lipids and choline.

Objective:To compare the outcomes of robot-assisted laparoscopic partial nephrectomy (RAPN) and laparoscopic partial nephrectomy (LPN) in the treatment of tumors in isolated kidney, and analyze the factors influencing postoperative renal function and long-term survival in patients.Methods:A retrospective analysis was conducted on clinical data of 67 patients with tumors in isolated kidney who underwent surgery at the Chinese PLA General Hospital from November 2010 to January 2022. There were 48 males and 19 females, with an average age of (58.6±10.1) years old. The patients were divided into RAPN group (43 cases) and LPN group (24 cases) based on the surgical approach. The RAPN group had a higher R.E.N.A.L. score than the LPN group [(8.7±1.5) vs. (7.9±1.7), P=0.042]. There were no statistically significant differences between the two groups in terms of age [(57.4±10.2) years old vs. (60.9±9.8) years old, P=0.185], body mass index (BMI) [(25.7±3.5) kg/m 2 vs. (25.1±3.6) kg/m 2, P=0.518], and preoperative serum creatinine [(102.9±31.6) μmol/L vs. (102.3±22.4) μmol/L, P=0.930]. Twelve cases underwent hypothermic treatment during surgery, with 9 cases(20.9%) in the RAPN group and 3 cases(12.5%) in the LPN group( P=0.596). Surgical time, intraoperative warm ischemia time, intraoperative blood loss, postoperative fasting time, perioperative complication rate, postoperative serum creatinine, and other indicators were compared between the two groups. Multiple linear regression analysis was used to identify factors affecting postoperative serum creatinine. Kaplan-Meier curves were employed to analyze patient prognosis, and log-rank tests were performed to compare the differences between the two groups. Multiple Cox regression analysis was used to identify factors influencing patient prognosis. Results:All surgeries were completed successfully with negative pathological margins. There were no statistically significant differences between the RAPN and LPN groups in terms of surgical time [(136.6±47.6) min vs. (125.3±34.4) min, P=0.311], intraoperative ischemia time [23.0 (16.0, 30.0) min vs. 19.0 (13.5, 27.5) min, P =0.260], intraoperative blood loss [50.0 (50.0, 100.0) ml vs. 50.0 (22.5, 100.0) ml, P=0.247], postoperative hospital stay [(6.6±3.5) days vs. (7.7±4.2) days, P=0.244], time to drain removal [4(3, 5) days vs. 5(3, 6) days, P =0.175], postoperative fasting time [(2.1±0.7) days vs. (2.2±1.0) days, P=0.729], perioperative complication rate [18.6% (8/43) vs. 16.7% (4/24), P=1.000], postoperative serum creatinine [145.2 (128.3, 191.3) μmol/L vs. 157.8 (136.2, 196.3) μmol/L, P =0.229], and pathological staging [T 1a/T 1b/T 2a/T 3a/T 4 stage: 32/7/1/3/0 case vs. 17/5/0/1/1 case, P=0.804]. Kaplan-Meier survival curves showed that the total survival rates at 1, 3, and 5 years after surgery were 94.7%, 84.9%, and 84.9% for the RAPN group, and 100.0%, 95.5%, and 95.5% for the LPN group, with no statistically significant difference in the log-rank test ( P=0.116). Excluding 10 patients with preoperative tumor metastasis (7 in the RAPN group and 3 in the LPN group), the progression-free survival rates at 1, 3, and 5 years after surgery were 84.8%, 81.1%, and 81.1% for the RAPN group, and 100.0%, 95.0%, and 90.0% for the LPN group, with no statistically significant difference in the log-rank test ( P =0.142). Multiple linear regression analysis showed that the use of hypothermic treatment during surgery significantly reduced postoperative serum creatinine ( B=-72.191, P=0.048). Multiple Cox regression analysis revealed that BMI ( HR=0.743, P=0.044), pathological T stage ( HR=4.235, P=0.018), and preoperative metastasis ( HR=18.829, P=0.035) were independent factors affecting patient overall survival time. A smaller BMI, higher pathological stage, and preoperative metastasis were associated with poorer prognosis. Conclusions:Despite the higher R. E.N.A.L. score and greater surgical difficulty in the RAPN group, RAPN achieved similar perioperative and prognostic results as the LPN, indicating RAPN advantages in treating tumors in isolated kidney. Appropriate intraoperative hypothermic treatment can better protect postoperative renal function. BMI, pathological T stage, and preoperative metastasis are independent factors affecting overall survival time.
