Objective To investigate the role and potential mechanisms of tumor necrosis factor alpha-inducible protein 8-like molecule 1(TNFAIP8L1)in acute liver injury in mice.Methods The second generation of C57BL/6J male wild-type(WT)mice and the C57BL/6J female TNFAIP8L1+/-mice and WT mice were selected to further self-breed the third generation of male TNFAIP8L1-/-mice and the third generation of WT male mice.Five normal third-generation male WT mice and five normal third-generation male TNFAIP8L1-/-mice were selected.The serum alanine aminotransferase(ALT)levels of the two types of normal mice were measured and compared.The infiltration of inflammatory cells and cell necrosis in the liver tissues of the two types of normal mice were observed after hematoxylin & eosin(HE)staining.Flow cytometry was used to detect the percentages of neutrophils(Neu),eosinophils(EOS),dendritic cells(DC),bone marrow-derived macrophages(BMDMs),and bone marrow-derived mononuclear cell(BMNCs)in the liver myeloid cell subsets of the two types of normal mice.Another 5 third-generation male WT mice and 4 third-generation male TNFAIP8L1-/-mice were selected to induce acute liver injury mouse models using lipopolysaccharide(LPS)/D-galactosamine(D-Gal).After 24 hours,the serum ALT levels of the two types of acute liver injury mice were detected and compared,the infiltration of inflammatory cells and cell necrosis in the liver tissues of the two types of acute liver injury mice were observed,and the percentages of Neu,EOS,DC,BMDMs and BMNCs in the liver myeloid cell subsets of the two types of acute liver injury mice were measured by using the above methods.Results There was no significant difference in the percentages of Neu,EOS,DC,BMDMs and BMNCs,and serum ALT levels in the livermyeloid cell subsets of normal WT mice and TNFAIP8L1-/-mice(P＞0.05).HE staining results of liver tissues in normal WT mice and TNFAIP8L1/mice showed that hepatic lobules were structurally complete and clear,hepatocytes were morphologically normal and arranged neatly,and there was no obvious inflammatory cell infiltration or cell necrosis.Twenty-four hours after acute liver injury,the percentages of Neu and BMNCs in the liver myeloid cell subsets and the serum ALT levels in the liver tissues of TNFAIP8L1-/-mice were significantly higher than those of WT mice(P＜0.05);there was no significant difference in the percentages of EOS,DC and BMDMs in the liver myeloid cell subsets of mice between the two groups(P＞0.05).In the liver tissues of WT mice with acute liver injury,hepatic lobules were structurally blurred,hepatocytes were swollen with scattered vacuolated steatosis,and a small amount of inflammatory cells were infiltrated.In the liver tissues of TNFAIP8L1/mice with acute liver injury,hepatic lobules were structurally non-existent,and hepatocytes were severely damaged and extensively necrotic,with a large amount of inflammatory cell infiltration.Conclusion The deficiency of the TNFAIP8L1 gene in mice does not affect the development of liver myeloid cells and the homeostasis of the liver.TNFAIP8L1 plays an inhibitory role in the occurrence and development of acute liver injury.TNFAIP8L1 gene deficiency aggravates LPS/D-Gal-induced acute liver injury,possibly by increasing Neu and BMNCs infiltration and recruiting other types of immune cells to infiltrate liver tissues,thereby exacerbating liver cell necrosis.

Objective To analyze the effect of nursing interventions based on the Information-Motivation-Behavioral Skills (IMB) model in patients with functional dyspepsia, in order to improve their psychological state and gastrointestinal motility, and provide reference for clinical nursing. Methods A total of 160 functional dyspepsia patients admitted to the First Affiliated Hospital of Xinxiang Medical College from December 2022 to June 2023 were chosen as the study subjects. They were randomly divided into control group and observation group, using a random number table method, with 80 cases in each group. Patients in control group were given routine nursing intervention, and patients in the observation group were treated nursing intervention based on IMB model. The psychological state, gastrointestinal motility andquality of life of the two groups were compared before and after intezrvention. Results After intervention, the scores of Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) in two groups were decreased, and the observation group was lower than that in the control group (P < 0.05). After intervention, the levels of gastrointestinal hormone nitric oxide (NO), serum motilin (MTL) andserum gastrin (GAS) in two groups were improved, and the levels of all indexes in the observation group were better than those in the control group (P < 0.05). After intervention, gastrointestinal quality of life index (GIQLI) of two groups was improved, and the observation group was higher than the control group, the difference was statistically significant (P < 0.05). Conclusion Nursing interventions based on the IMB model are beneficial for alleviating anxiety and depression in patients with functional dyspepsia, effectively enhancing gastrointestinal motility and vitality, and improving their quality of life.

ObjectiveTo review the drug information and research progress on oral Chinese patent medicines in the treatment of cardiac arrhythmia to identify existing problems and provide references for follow-up research. MethodChinese patent medicines against cardiac arrhythmia were retrieved from the three major drug catalogues，Yaozh.com，and relevant guidelines with arrhythmia as the retrieval term. The instructions for included Chinese patent medicines were retrieved through Yaozh.com and specific information was extracted. The research articles on Chinese patent medicines included were retrieved from the five databases，and the information meeting the inclusion and exclusion criteria was extracted and displayed in the form of text description and graphs after statistical analysis. ResultSixty-five oral Chinese patent medicines were included in this study，with the main functions of activating the blood and resolving stasis. The average daily cost of medicines was 8.17 yuan，and there were 42 medicines with an average daily cost of less than 10 yuan，showing a moderate medicine cost. A total of 351 research articles on Chinese patent medicines were screened out，including 259 randomized controlled trials （RCTs），16 non-RCTs，eight non-controlled trials，62 systematic reviews，two guidelines，and two expert consensuses. Eighteen types of Chinese patent medicines were involved，whose clinical trials had been conducted in 28 provinces，cities，autonomous regions，and municipalities in China. Wenxin granules and Shensong Yangxin capsules were the top medicines under investigation，accounting for 75.21% of all research articles. Among the included studies，the most common comparison design was Chinese patent medicine combined with western medicine vs western medicine （64.25%）. The outcome evaluation was mainly based on clinical efficacy，symptom efficacy，arrhythmia efficacy，adverse reactions，and heart rate changes. ConclusionThe number of clinical studies of oral Chinese patent medicines against cardiac arrhythmia varies greatly，but traditional Chinese medicine （TCM） syndrome differentiation thinking is less considered in practical application. Due to unstandardized clinical research and low-quality literature，further advancement is required in the future.

For wild natural medicine, unanticipated biodiversity as species or varieties with similar morphological characteristics and sympatric distribution may co-exist in a single batch of medical materials, which affects the efficacy and safety of clinical medication. DNA barcoding as an effective species identification tool is limited by its low sample throughput nature. In this study, combining DNA mini-barcode, DNA metabarcoding and species delimitation method, a novel biological sources consistency evaluation strategy was proposed, and high level of interspecific and intraspecific variations were observed and validated among 5376 Amynthas samples from 19 sampling points regarded as "Guang Dilong" and 25 batches of proprietary Chinese medicines. Besides Amynthas aspergillum as the authentic source, 8 other Molecular Operational Taxonomic Units (MOTUs) were elucidated. Significantly, even the subgroups within A. aspergillum revealed here differ significantly on chemical compositions and biological activity. Fortunately, this biodiversity could be controlled when the collection was limited to designated areas, as proved by 2796 "decoction pieces" samples. This batch biological identification method should be introduced as a novel concept regarding natural medicine quality control, and to offer guidelines for in-situ conservation and breeding bases construction of wild natural medicine.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.

Objective:To investigate the correlation between three-dimensional histogram analysis of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)and Gleason score(GS)in prostate cancer(Pca)from two hospital, and its diagnostic efficacy for discriminating low-grade from high-grade Pca.Methods:A total of 102 pathologically confirmed Pca patients in the First Affiliated Hospital of Zhejiang Chinese Medical University and Hangzhou Traditional Chinese Medical Hospital(TCM Hospital)Affiliated to Zhejiang Chinese Medical University from January 2017 to October 2020 were retrospectively analyzed.The quantitative parameters of Pca, including transport constant(K trans), rate constant(K ep), percent volume of the extravascular extracellular space(V e)and fraction of the Intraplasmic contrast volume(V p), were obtained by manually layer by layer delineating of interested regions of all lesions on the original DCE-MRI imaging.Then the three-dimensional histogram analysis of the above parameters were performed to obtain the minimum, maximum, median, mean, area, 10 thpercentile, 25 thpercentile, 75 thpercentile and 90 thpercentile.The correlations between quantitative parameters and GS, and diagnostic efficiencies were analyzed. Results:102 Pca patients were divided into low-grade prostate cancer group(GS≤3+ 4)(n=44)and high-grade Pca group(GS≥4+ 3)(n=58). There were no statistically significant differences in age and location of lesions between the two groups( P>0.05), but there were statistically significant differences in Gleason score, PSA level and lesion diameter between the two groups( U=0.000, 730.000, 711.000, all P<0.05). The median, mean, 10 thpercentile, 25 thpercentile, 75 thpercentile, 90 thpercentile derived from K trans, and K ep(median, mean, 10%, 25%, 75%, 90%)together with maximum of K transand mean for V e were positively correlated with GS( r=0.405 to 0.583, P<0.05), in which mean of K transhad the highest positive correlation( r=0.583, P=0.000). The histogram parameters derived from V pwere negatively correlated with GS( r=-0.301 to 0.341, P<0.05). The area under ROC of 75th percentile derived from K transwas the highest(0.832). When the cut-off value of 75 thpercentile derived from K transwas ≥0.680/min, its Youden index, sensitivity, and specificity were 0.594, 0.776, 0.818, respectively. Conclusions:The three-dimensional histogram of DCE-MRI quantitative parameters has correlation with GS in Pca patients, can be used to discriminate low-grade from high-grade Pca.

The frozen section (FS) technology has been widely used in the process of surgical pathology since its time-saving nature exhibited superiority over traditional paraffin method. Therefore FS, of great value in providing preliminary pathological diagnosis, offers guidance in the extension of surgical resection. However, it remains controversial whether the early-stage lung adenocarcinoma could be accurately identified in FS. This review aims to generalize the studies concerning the accuracy of FS in identifying early-stage lung adenocarcinoma, analyzing the interference factors, comparing the similarities and differences between frozen sections and traditional paraffin sections. It also gives insight into whether FS can provide significant guidance for surgeons to perform resection on early-stage lung adenocarcinoma.

Objective:To explore the clinical characteristics and follow-up outcomes of a pedigree of maturity onset diabetes of the young (MODY) induced by a novel mutation of glucokinase (GCK).Methods:The clinical features and laboratory data of a pedigree diagnosed with GCK-MODY in Peking Union Medical College Hospital was analyzed. Genomic DNA was extracted, and Sanger sequencing was performed to detect the gene mutation of the family members. The proband and her father were followed up for 3 years. Wanfang and PubMed were used to search literatures on follow-up studies for treatment of GCK-MOYD.Results:Both the proband and her father were found to have a novel mutation on the GCK gene located in exo10 c.1348G.T (p. Ala450Thr). The proband was treated with diet and exercise control only. At the end of the follow-up, her fasting plasma glucose (FPG, 6.8 mmol/L), 2 h postprandial plasma glucose (2hPG, 7.4 mmol/L), and glycated hemoglobin (HbA1c, 6.3%) were all within the control targets. Additionally, the levels homeostasis model assessment of insulin resistance (HOMA-IR) tended to improved comparing to that at baseline (4.09 to 2.32), and glucose disposition index (DI) was improved compared with baseline (16.22 to 20.05). As to the proband′s father, the treatment with insulin plus acarbose was converted to sulfonylureas monotherapy. His FPG and 2hPG mostly were within the target range, and the levels of HbA1c were significantly reduced by 0.5%-0.7% when compared to that at baseline. The HOMA-IR or islet beta cell function was comparable to those at baseline.Conclusions:Screening patients whose clinical performance meets GCK-MODY and their family members with proper genetic testing is of great importance to reduce misdiagnosis of GCK-MODY, so as to obtain a better glucose control without unnecessary over-treatment and protect islet beta cell function.

Objective:To evaluate the clinical characteristics and prognosis of gallbladder cancer (GBC) patients in China.Methods:This retrospective multicenter cohort study enrolled 3 528 consecutive GBC patients diagnosed between January 2010 to December 2017 in 15 hospitals from 10 provinces. There were 1 345 (38.12%) males and 2 183 (61.88%) females.The age of diagnosis was (63.7±10.8) years old (range: 26 to 99 years old) .There were 213 patients (6.04%) in stage 0 to Ⅰ, whereas 1 059 (30.02%) in stage Ⅱ to Ⅲ, 1 874 (53.12%) in stage Ⅳ, and 382 (10.83%) unavailable. Surgery was performed on 2 255 patients (63.92%) . Three hundred and thirty-six patients received chemotherapy or radiotherapy (9.52%; of which 172 were palliative); 1 101 (31.21%) received only supportive treatment.The patient source, treatment and surgery, pathology, concomitant gallstone, and prognosis were analyzed.Results:Among the 3 528 GBC patients, 959 (27.18%) were from East China, 603 (17.09%) from East-North China, 1 533 (43.45%) from Central China, and 433(12.27%) from West China. Among the 1 578 resectable tumor, 665 (42.14%) underwent radical surgery, 913 (57.86%) underwent surgery that failed to follow the guidelines.Eight hundred and ninety-one (56.46%) patients were diagnosed before surgery, 254 (16.10%) during surgery, and 381 (24.14%) after surgery (time point of diagnosis couldn′t be determined in 52 patients) .Among the 1 578 patients with resectable tumor, 759 (48.10%) had concomitant gallstone.Among the 665 patients underwent radical surgery, 69 (10.4%) showed positive resection margin, 510 (76.7%) showed negative resection margin, and 86 (12.9%) unreported margin status.The 5-year overall survival rate (5yOS) for the 3 528-patient cohort was 23.0%.The 5yOS for patients with resectable tumor was 39.6%, for patients with stage ⅣB tumor without surgery was 5.4%, and for patients with stage ⅣB tumor underwent palliative surgery was 4.7%.Conclusions:More than half GBC patients in China are diagnosed in stage Ⅳ.Curative intent surgery is valuable in improving prognosis of resectable GBC.The treatment of GBC needs further standardization.Effective comprehensive treatment for GBC is in urgent need.
