Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine （Part 8）： Quality Evaluation with AGREE Ⅱ and RIGHT / 中医杂志

ObjectiveTo evaluate the methodological and reporting quality of clinical practice guidelines for Chinese patent medicine （CPM） with internationally recognized tools the appraisal of guidelines for research and evaluation （AGEREE） Ⅱ and reporting items for practice guidelines in healthcare （RIGHT）， thereby providing refe-rence for the clinical application and future development of CPM guidelines. MethodsDatabases including CNKI， VIP， Wanfang and Sinomed were searched for CPM guidelines， as well as medlive.cn， websites of China Association of Chinese Medicine and Chinese Medical Association， and reference lists of the included papers. The quality of the guidelines was evaluated using the AGREE Ⅱand RIGHT tools， and consistency tests were performed using Interclass Correlation Coefficient， and descriptive analysis and chi-square test were used to analyze the reporting rate for each domain and the average score for each item. ResultsFinally， 140 CPM guidelines were included， of which 51 were disease-oriented and 89 were drug-oriented， all of which were issued by China. For 51 disease-oriented CPM guidelines， the highest average score of all six AGREE Ⅱ domains was 73.32% for clarity， and the lowest was 26.80% for application； for 89 drug-oriented CPM guidelines， the highest average score was 55.62% for scope and purpose， and the lowest was 31.32% for rigour of development. In terms of the seven domains of the RIGHT checklist， the highest reporting rate was 68.26% for background， and lowest was 27.45% for other areas regarding the disease-oriented CPM guidelines； the highest reporting rate was 61.31% for background， and the lowest was 4.49% for other areas regarding drug-oriented CPM guidelines. The average reporting rate was higher for disease-oriented than drug-oriented CPM guidelines in three domains of AGREE Ⅱ （rigour of development， clarity of presentation， editorial independence）， as well as four domains of RIGHT checklist （basic information， evidence， funding and declaration and management of interests， and other areas）. ConclusionThe overall methodology and reporting quality of the current CPM guidelines still need to be improved. It is recommended that future guideline development teams should strictly refer to the AGREE Ⅱ and RIGHT checklist， and take into account of the characteristics of CPM guidelines and relevant methodo-logical suggestions in the development and reporting of CPM guidelines， thereby guiding the clinical use of CPM in a better way.

Then the searched information should be summarized and prioritized with the principle that taking drug instructions as the basis and other-sources information for check and supplementation. Finally， methodological recommendations for the retrieval and synthesis of key information on rational drug use in guideline recommendations has been formed.

Population pharmacokinetics of mycophenolic acid in pediatric patients with primary IgA nephropathy / 中国药房

OBJECTIVE To develop a population pharmacokinetic （PPK） model for mycophenolate mofetil active metabolite mycophenolic acid （MPA） in children with primary IgA nephropathy， explore the factors affecting the pharmacokinetic parameters of MPA， and provide a basis for clinical individualized therapy. METHODS Retrospective collection was conducted on 636 concentrations and clinical data from 47 pediatric patients with primary IgA nephropathy. PPK analysis was carried out by using the nonlinear mixed-effects model； the covariates were tested with a stepwise method. Goodness-of-fit plots， Bootstrap and visual predictive check were employed to evaluate the final model. RESULTS The pharmacokinetics of MPA in children with IgA nephropathy in vivo conformed to the first-order absorption and elimination two-compartment model （objective function value of 3 276.31）. Covariate analysis suggested that body weight and albumin （ALB） levels were significant influencing factors on apparent clearance rate and apparent distribution volume. The typical values of PPK parameters of MPA in the final model were as follows： the central room had a distributed volume of 5.79 L， the clearance rate was 4.06 L/h， the volume of peripheral ventricular distribution was 430.93 L， the clearance rate between compartments was 15.40 L/h， the oral absorption rate constant was 1.29 h－1. After verification， most of the predicted corrected observed concentration points were within the 90% confidence interval of the predicted corrected simulated concentration， indicating that the MPA final model had good predictive performance. CONCLUSIONS The PPK model of MPA in children with primary IgA nephropathy is established in this study， identifying body weight and ALB levels are significant factors affecting MPA metabolism.

Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine（Part 4）： Evidence Retrieval and Evaluation / 中医杂志

The retrieval and evaluation of evidence is the basis for the development of clinical practice guidelines for Chinese patent medicine. As traditional Chinese medicine has a different development trajectory and utilization characteristics from modern medicine， there is certain differences in terms of evidence composition， retrieval and integration.This paper discussed multi-source body of evidence on Chinese patent medicine based on modern evidence-based medicine and ancient medical literature， and summarized the retrieval strategy as well as the possible problems and solving methods. For different types of evidence on Chinese patent medicine， the corresponding evaluation tools have been recommended， and the order to integrate the evidence based on the quality of the evidence from high to low is suggested. Finally， a multi-source based evidence retrieval-evaluation-integration scheme for Chinese patent medicine has been formed， which will provide a methodological reference for practitioners in the development of clinical practice guidelines for Chinese patent medicine.

Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine（Part 3）： Identification of Clinical Questions / 中医杂志

The identification of clinical questions for clinical practice guidelines of Chinese patent medicine （CPM） is important for subsequent evidence retrieval， evaluation of evidence quality， formation of recommendations. This paper described a methodological proposal for the identification of clinical questions for CPM guidelines to highlight the characteristics of Chinese patent medicine and reflect its effect in specific stage of the disease. Considering four aspects， namely， the drug of Chinese patent medicine （D）， the specific disease stage （S）， comparison （C）， and specific outcome （O）， DSCO framework has been proposed to formulate the clinical questions. Multi-source information through scientific research， policy or standard documents， and clinical data are suggested for collecting clinical questions， and clear selection criteria should be set to finalize the clinical questions to be addressed by the guideline. In addition， the above process needs to be transparently and publicly reported in order to ensure the clarity and completeness of the guidelines.

Latent period and incubation period with associated factors of COVID-19 caused by Omicron variant / 中华预防医学杂志

Objective: To estimate the latent period and incubation period of Omicron variant infections and analyze associated factors. Methods: From January 1 to June 30, 2022, 467 infections and 335 symptomatic infections in five local Omicron variant outbreaks in China were selected as the study subjects. The latent period and incubation period were estimated by using log-normal distribution and gamma distribution models, and the associated factors were analyzed by using the accelerated failure time model (AFT). Results: The median (Q1, Q3) age of 467 Omicron infections including 253 males (54.18%) was 26 (20, 39) years old. There were 132 asymptomatic infections (28.27%) and 335 (71.73%) symptomatic infections. The mean latent period of 467 Omicron infections was 2.65 (95%CI: 2.53-2.78) days, and 98% of infections were positive for nucleic acid test within 6.37 (95%CI: 5.86-6.82) days after infection. The mean incubation period of 335 symptomatic infections was 3.40 (95%CI: 3.25-3.57) days, and 97% of them developed clinical symptoms within 6.80 (95%CI: 6.34-7.22) days after infection. The results of the AFT model analysis showed that compared with the group aged 18-49 years old, the latent period [exp(β)=1.36 (95%CI: 1.16-1.60), P<0.001] and incubation period [exp(β)=1.24 (95%CI: 1.07-1.45), P=0.006] of infections aged 0-17 years old were prolonged. The latent period [exp(β)=1.38 (95%CI: 1.17-1.63), P<0.001] and the incubation period [exp(β)=1.26 (95%CI: 1.06-1.48), P=0.007] of infections aged 50 years old and above were also prolonged. Conclusion: The latent period and incubation period of most Omicron infections are within 7 days, and age may be a influencing factor of the latent period and incubation period.

Response characteristics of tislelizumab combined with chemotherapy in first-line treatment of locally advanced or metastatic non-squamous non-small cell lung cancer / 中华肿瘤杂志

Objective: To investigate the response characteristics of patients with locally advanced/metastatic non-squamous non-small cell lung cancer (nsq-NSCLC) treated with tislelizumab in combination with chemotherapy in the first line. Methods: Patients with nsq-NSCLC who achieved complete or partial remission after treatment with tislelizumab in combination with chemotherapy or chemotherapy alone in the RATIONALE 304 study, as assessed by an independent review board, were selected to analyze the response characteristics and safety profile of the responders. Time to response (TTR) was defined as the time from randomization to the achievement of first objective response. Depth of response (DpR) was defined as the maximum percentage of tumor shrinkage compared with the sum of the baseline target lesion length diameters. Results: As of January 23, 2020, 128 patients treated with tislelizumab in combination with chemotherapy achieved objective tumor response (responders), representing 57.4%(128/223) of the intention-to-treat population, with a TTR of 5.1 to 33.3 weeks and a median TTR of 7.9 weeks. Of the responders (128), 50.8%(65) achieved first remission at the first efficacy assessment (week 6), 31.3%(40) at the second efficacy assessment (week 12), and 18.0%(23) at the third and subsequent tumor assessments. The percentages of responders who achieved a depth of tumor response of 30% to <50%, 50% to <70% and 70% to 100% were 45.3%(58/128), 28.1%(36/128) and 26.6%(34/128), respectively, with median progression-free survival (PFS) of 9.0 months (95% CI: 7.7 to 9.9 months), 11.5 months (95% CI: 7.7 months to not reached) and not reached (95% CI: 11.8 months to not estimable), respectively. Tislelizumab plus chemotherapy were generally well tolerated in responders with similar safety profile to the overall safety population. Conclusion: Among responders to tislelizumab in combination with chemotherapy for nsq-NSCLC, 82.0%(105/128) achieves response within the first two tumor assessments (12 weeks) and 18.0%(23/128) achieves response at later (18 to 33 weeks) assessments, and there is a trend toward prolonged PFS in responders with deeper tumor response.

Effect of Electroacupuncture at Proximal and Distal Acupoints on Pain-inducing Substances， Macrophages and Related Inflammatory Factors in Myofascial Pain Syndrome Model Rats / 中医杂志

ObjectiveTo explore the possible peripheral analgesic mechanism of electroacupuncture （EA） at promimal and distal acupoints in treatment of myofascial pain syndrome （MPS）. MethodsTwenty-four SD rats were randomly divided into blank group， model group， proximal group， and distal group， with six rats in each group. MPS model was prepared by “strike combined with centrifugal exercise” in all groups except for the blank group. After modeling， the rats in the proximal group received EA at the local myofascial trigger points （MTrPs）， namely the Ashi points， with dilatational waves of frequency of 2/100 HZ and voltage of 2-4 V， current intensity depending on a slight trembling of the left lower limbs， once a day， 15min each time，for 14 days. The rats in the distal group received EA at “Yanglingquan” （GB 34） and “Yinlingquan” （SP 9）， with the same operations as the proximal group. The rats in the blank group and the model group were only grasped and hedged， without other interventions. After intervention， the paw withdrawl mechanical threshold （PWMT） was measured， and variability between the left and right hind paws was calculated. Musculoskeletal ultrasound imaging and electromyography monitoring were performed on the left lower extremity vastus medialis. The morphological changes of vastus medialis muscle of the left lower extremity were observed by HE staining. The positive expression of substance P （SP）， calcitonin gene-related peptide （CGRP）， CD68 and CD206 in muscle tissue was detected by immunohistochemistry. Abdominal aortic serum interleukin-1β （IL-1β）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， interleukin-10 （IL-10）， and interleukin-8 （interleukin-8） were detected by ELISA. ResultsCompared to those in the blank group， the fibers of the vastus medial muscle of the rats in the model group were broken and distorted with thickness in variation， and the myofascia was broken， with fibrillation potential， enlarged muscle cells， inward moved nucleus， and widened muscle space； the variability of PWMT between the left and right hind paws significantly increased， as well as the levels of SP， CGRP， CD68， and CD206 in the vastus medialis muscle （P＜0.01）， and the serum IL-8 and TNF-αlevels were significantly elevated （P＜0.05 or P＜0.01）. Compared to those in the model group， the muscle fibers in the proximal and distal group were complete in shape and arranged in an orderly manner， with continued non-broken myofascia， regular shape of muscle cells， and significantly reduced level of IL-8 （P＜0.01）； the amplitude and frequency of spontaneous discharge in the proximal group significantly decreased， as well as the variability of PWMT between the left and right hind paws， and the levels of SP， CGRP， and CD68 in the vastus medialis muscle， while the CD206 level increased significantly （P＜0.05 or P＜0.01 ）； there was complex discharges in the distal group， with significantly decreased level of CD68 in the vastus medialis muscle and increased level of CD206 （P＜0.01）. Compared to the proximal group， the level of IL-8 in the distal group was significantly higher （P＜0.05）. ConclusionsEA at proximal acupoints can significantly improve the pain threshold and local muscle tissue morpho-logy in rats， and its mechanism may be related to reducing the levels of pain-causing substances and related inflammatory factors and promoting the polarization of macrophages. The analgesic effect of EA at distal acupoints is not obvious， and the mechanism is still unclear.

Clinical application of non-invasive myocardial work imaging in ST-segment elevation myocardial infarction patients with left ventricular remodeling after percutaneous coronary intervention / 中华超声影像学杂志

Objective:To explore the application value of non-invasive myocardial work imaging in evaluating the cardiac function of ST-segment elevation myocardial infarction (STEMI) patients with left ventricular remodeling (LVR) after percutaneous coronary intervention (PCI).Methods:One hundred and twenty-six patients with STEMI undergoing PCI in General Hospital of Ningxia Medical University from December 2021 to September 2022 were prospectively collected and divided into left ventricular remodeling group (LVR group, 34 cases) and non left ventricular remodeling group (NLVR group, 92 cases) according to whether there was left ventricular remodeling 3 months after surgery. General data were collected. Routine echocardiography and noninvasive myocardial work imaging were performed before, 1 week, 1 month, and 3 months after surgery, the differences in the above parameters between the two groups were compared. Pearson correlation analysis was used to analyze the correlation between the indicators.Logistic regression analysis was used to determine the independent risk factors of left ventricular remodeling after STEMI, and a predictive model was obtained. The diagnostic value of the model was judged by ROC curve.Results:①General information comparison: There were statistically significant differences between the two groups in BMI, systolic blood pressure, diastolic blood pressure, average number of stents implanted, and history of hyperlipidemia (all P<0.05), but there was no significant difference in other data (all P>0.05). There was no statistically significant difference in two-dimensional transthoracic echocardiography (2D-TTE) parameters and non-invasive myocardial work (MW) parameters between the two groups before and 1 week after operation (both P>0.05). ②2D-TTE parameter comparison: LVESV and LVEDV at 3 months after PCI in the LVR group were significantly higher than those in the NLVR group, and LVEF and E/A were significantly lower than those in the NLVR group (all P<0.05); There were no significant differences in other indexes between the two groups by conventional echocardiography at 3 months after PCI(all P>0.05). ③Comparisons of noninvasive myocardial work parameters: GLS, GWE, GWI, GCW at 1 month and 3 months after PCI in the LVR group were significantly lower than those in the NLVR group, and GWW were significantly higher than those in the NLVR group ( P<0.001). ④Correlation analysis: GLS, GWE, GCW, GWI and LVEDV were negatively correlated at 1 month after operation ( r=-0.42, -0.38, -0.50, -0.53, all P<0.001), GWW was positively correlated with LVEDV ( r=0.45, P<0.001). ⑤Logistic regression analysis: GLS<17%, GCW<1 900 mmHg%, GWW>105 mmHg%, and GWE<90 mmHg% at 1 month after PCI were independent predictors for LVR in STEMI patients after PCI (all P<0.05). The predictive model was Logit (P)=0.692GLS+ 0.804GCW+ 0.972GWW+ 0.880GWE. The AUC of this model was 0.886, 95% CI=0.845-0.926, which was significantly higher than single index, the sensitivity was 0.86, and the specificity was 0.79. Conclusions:GLS, GWE, GWI, GCW are positively correlated with LVR, while GWW is negatively correlated with left ventricular remodeling. Noninvasive myocardial work parameters are independent risk factors for left ventricular remodeling in patients with STEMI after PCI surgery. This technique can be used to evaluate LVR and has great clinical application value.

Application of union physio-psycho-social assessment questionnaire in screening anxiety and depression in outpatients from general hospital / 中华行为医学与脑科学杂志

Objective:To explore the application of union physio-psycho-social assessment questionnaire (UPPSAQ-70) in screening anxiety and depression in outpatients from general hospital.Methods:A total of 510 outpatients from Peking Union Medical College Hospital from June 2020 to November 2021 were recruited.They were assessed with UPPSAQ-70, self-rating anxiety scale (SAS) and self-rating depression scale (SDS). The internal consistency of the UPPSAQ-70 was tested by Cronbach′s α coefficient.The convergent validity of the UPPSAQ-70 was evaluated by examining correlations with the SAS and SDS.Clinical diagnosis, being considering as the " gold standard" , was used to test criterion validity.Result:The UPPSAQ-70 showed good item characteristics and reliability (Cronbach α=0.947). The UPPSAQ-70 total score showed significant correlations with SAS( r=0.843, P<0.01) and SDS ( r=0.852, P<0.01). The area under the curve (AUC) of the UPPSAQ-70 was 0.875 ( P<0.01), the cut-off value was 65 points with the sensitivity 83.2% and the specificity 75.5%.The AUC of the SAS and SDS was 0.848 and 0.808 respectively(both P<0.001). For the SAS(standard score of 50 as the cut-off value), the sensitivity was 47.3%, and specificity was 92.5%.For the SDS(standard score of 53 as the cut-off value), the sensitivity was 62.9%, and specificity was 86.8%. Conclusion:UPPSAQ-70 has high sensitivity and is more suitable for screening of anxiety and depression in general hospital outpatients.

Association of the appendicular skeletal muscle mass to fat mass ratio in early pregnancy with the risk of development of gestational diabetes mellitus / 中华临床营养杂志

Objective:To assess the association of appendicular skeletal muscle mass(ASM) to fat mass(FM) ratio in early pregnancy with the risk of gestational diabetes mellitus (GDM).Methods:A total of 468 pregnant women who visited the Nutritional Department of Peking Union Medical College Hospital or Shunyi Maternal and Child Care Service Center in 2018 and 2019 were recruited. Detailed information and clinical data were collected. The body components were measured using the bioelectrical impedance analysis (BIA) method during early pregnancy (< 14 weeks) and the ASM to FM ratio was calculated. The patients were divided into the GDM group and normal glucose tolerance (NGT) group according to the results of the oral glucose tolerance test (OGTT) performed during 24-28 weeks. Binary logistics regression was used to explore the correlation between the ASM/FM ratio and the risk of GDM. The receiver operator characteristic (ROC) curve of subjects was used to evaluate the predictive value of ASM/FM ratio for GDM and the cut-off value was reported.Results:Compared to the NGT group, the ASM and FM in early pregnancy in the GDM group were significantly higher, while the ASM/FM ratio was significantly lower. A lower ASM/FM ratio in early pregnancy was one of the risk factors of developing GDM. The cut-off value of the ASM/FM ratio was 0.809. The area under the ROC curve for predicting GDM increased from 68.1% to 72.3% when ASM/FM ratio was incorporated, with a significant difference by Delong test ( P = 0.006). Conclusion:Inadequate muscle mass would increase the risk of GDM and the ASM/FM ratio could serve as a predictor of GDM.

Objective:To investigate the changes in serum miRNA-21 and miRNA-4534 levels in patients with lung adenocarcinoma and their relationships with pathological characteristics and prognosis.Methods:A total of 148 patients with lung adenocarcinoma who received treatment in the First People's Hospital of Huzhou from January 2018 to January 2019 were included in the observation group. An additional 100 healthy controls who concurrently received physical examinations were included in the control group. The relative expression of serum miRNA-21 and miRNA-4534 was measured using real-time fluorescence quantitative PCR. The relative expression of serum miRNA-21 and miRNA-4534 was compared between the two groups. The relative expression of serum miRNA-21 and miRNA-4534 was compared between patients with different pathological characteristics. Total survival time was compared between patients with high and low miRAN-21 expression and between patients with high and low miRNA-4534 expression.Results:The relative expression of miRNA-21 and miRNA-4534 in the observation group was 3.27 ± 0.87 and 6.74 ± 1.56, respectively, which was significantly higher than 1.00 ± 0.01 and 1.02 ± 0.02 in the control group ( t = 20.07, 36.64, both P < 0.05). There was no significant difference in the relative expression of miRNA-21 and miRNA-4534 between different genders, ages, body mass index values, tumor regions, and tumor diameters (all P > 0.05). The relative expression of serum miRNA-21 in patients with stage Ⅲ-Ⅳ lung adenocarcinoma was 4.45 ± 1.05, which was significantly higher than 1.92 ± 0.53 in patients with stage Ⅰ-Ⅱ lung adenocarcinoma. The relative expression of serum miRNA-21 in patients with lymph node metastasis was higher than that in patients without lymph node metastasis (4.97 ± 1.28 vs. 1.34 ± 0.60, t = 17.53, 23.48, both P < 0.05). The relative expression of miRNA-4534 in patients with stage Ⅲ-Ⅳ lung adenocarcinoma was higher than that in patients with stage Ⅰ-Ⅱ lung adenocarcinoma (8.97 ± 1.85 vs. 4.48 ± 1.09, t = 17.17, P < 0.05). The relative expression of miRNA-4534 in patients with lymph node metastasis was higher than that in patients without lymph node metastasis (9.65 ± 1.35 vs. 3.78 ± 0.91, t = 30.59, P < 0.05). The total survival time in patients with high miRNA-21 expression was shorter than that in patients with low miRNA-21 expression [(18.37 ± 4.35) months vs. (29.93 ± 3.24) months, t = 18.45, P < 0.05]. The total survival time in patients with high miRNA-4534 expression was shorter than that in patients with low miRNA-4534 expression [(17.56 ± 4.21) months vs. (30.43 ± 3.63) months, t = 19.97, P < 0.05)]. Conclusion:Patients with lung adenocarcinoma have high expression of miRNA-21 and miRNA-4534 in the serum, which is closely related to the tumor-node-metastasis stage, lymph node metastasis, and prognosis.

Objective:To establish the best evidence-based approach for early fluid resuscitation management in patients with severe acute pancreatitis (SAP).Methods:A literature search was conducted utilizing evidence-based nursing methods to identify relevant evidence on the management of early fluid resuscitation in patients with SAP. The search followed the hierarchical order of the " 6S" evidence pyramid, including databases such as China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (SinoMed), Wanfang Database, UpToDate, NICE, RNAO Guidelines Network, Pancreatology International, WHO Association Website, JBI, Cochrane, PubMed, EMBASE, and CINAHL. The search was limited to articles published from the establishment of each database to March 2022. The literature quality evaluation tools and an evidence pre-grading system from the JBI Evidence-Based Health Care Center were employed to assess the quality of the literature included in the study. Additionally, the FAME structure was utilized to evaluate the feasibility, appropriateness, clinical significance, and validity of the evidence.Results:Nine articles were finally incorporated into the analysis, including four guidelines, one evidence summary, two systematic reviews, and two expert consensus articles. 21 pieces of evidence pertaining to early fluid resuscitation management in patients with SAP was summarized, encompassing five key aspects: resuscitation timing, type of fluid infusion, total volume and speed of fluid infusion, dynamic monitoring, and fluid resuscitation goals. It was advisable for patients diagnosed with SAP to promptly receive fluid resuscitation, ideally within 72 hours of diagnosis. The initial choice for fluid resuscitation was lactated Ringer′s solution, with the addition of human albumin as a supplementary colloid solution. The quantity of fluid administered within the first 24 hours of rehydration should constitute approximately 33.3% of the total rehydration volume within the 72 hours time-frame. In the case of patients experiencing early shock or dehydration, it was advised that the fluid rate administered should be 5-10 ml·kg -1·h -1 within the first 24 hours of admission. Additionally, an infusion of 20 ml/kg of fluid can be administered within the initial 30-45 minutes. It was recommended to assess the adequacy of early fluid resuscitation every 4-6 hours, ensuring that the resuscitation objective could meet at least two of the following criteria: urine output of 0.5-1 ml·kg -1·h -1, mean arterial pressure of 65-85 mmHg, central venous pressure of 8-12 mmHg, heart rate below 120 beats/min, central venous oxygen saturation of at least 70%, and a decrease in hematocrit levels to 30%-35%. Conclusions:The most compelling evidence supporting the implementation of early fluid resuscitation management in patients with SAP is derived from an evidence-based nursing approach, which could effectively improve patient care outcomes.

Study on LASSO regression prediction of lymph nodes around hepatic artery metastasis based on blood routine index in patients with distant gastric cancer / 中国医师进修杂志

Objective:To investigate the value of LASSO regression prediction of lymph nodes around hepatic artery metastasis based on blood routine index in patients with distant gastric cancer.Methods:The clinical data of 110 patients with distant gastric cancer from June 2018 to February 2022 in Jieshou People′s Hospital were retrospective analyzed. Among them, 43 patients had lymph nodes around hepatic artery metastases (metastasis group), and 67 patients have not lymph nodes around hepatic artery metastases (non-metastasis group). The basic clinical data were recorded; the routine blood test was detected, the indexes including white blood cell count, neutrophil percentage, lymphocyte count, platelet count, lymphocyte percentage, acidophil count, basophils count, hemoglobin, red blood cell distribution width (RDW), platelet distribution width (PDW) and neutrophil to lymphocyte ratio (NLR). The R language 4.1.0 software "grpreg" package was used to establish a Group LASSO Logistic regression analysis model to finally select the factors predicting lymph node around hepatic arterial metastasis in patients with distal gastric cancer. Nomogram were made using R language 3.5.3 software package and rms program package, calculated the consistency index (C-index), and the accuracy of the model was evaluated by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve.Results:The white blood cell count, neutrophil percentage, NLR and lymphocyte percentage in metastasis group were significantly higher than those in non-metastasis group: (12.16 ± 1.62) × 10 9/L vs. (9.38 ± 2.64) × 10 9/L, (73.36 ± 6.94)% vs. (52.21 ± 6.23)%, 3.23 ± 0.63 vs. 2.35 ± 0.13 and (48.62 ± 3.64)% vs. (31.02 ± 2.94)%, the acidophil count and basophils count were significantly lower than those in non-metastasis group: (0.31 ± 0.03) × 10 9/L vs. (0.36 ± 0.04) × 10 9/L and (0.08 ± 0.01) × 10 9/L vs. (0.09 ± 0.02) × 10 9/L, the degree of differentiation and TNM stage were also worse than those in non-metastasis group, and there were statistical differences ( P<0.01). The nomogram was constructed to predict lymph nodes around hepatic artery metastasis based on the degree of differentiation, TNM stage, white blood cell count, neutrophil percentage, NLR, lymphocyte percentage, acidophil count and basophils count in patients with distant gastric cancer, the scores of each indexes were 20.64, 26.42, 32.83, 25.78, 38.46, 35.65, 29.06 and 18.26 scores, the total score (227.10 scores) was the incidence of the nomogram model (29.82%). The validation result showed C-index of 0.819 and 0.806 (95% CI 0.785 to 0.864 and 0.779 to 0.816), and the correction curves for both sets were fitted well to the ideal curve with AUC of 0.801 and 0.810 (95% CI 0.784 to 0.826 and 0.795 to 0.852), and the decision curve showed high net benefit value with threshold probability from 1% to 9%. Conclusions:LASSO regression model combined with white blood cell count, neutrophil percentage, NLR, lymphocyte percentage, acidophil count and basophils count is ideal to predict lymph nodes around hepatic artery metastasis in patients with distant gastric cancer.
