In recent years, the spread of clubroot disease caused by Plasmodiophora brassicae infection has seriously affected the yield and quality of Brassica juncea (L.) Czern.. The cascade of mitogen-activated protein kinases (MAPKs), a highly conserved signaling pathway, plays an important role in plant responses to both biotic and abiotic stress conditions. To mine the MAPK genes related to clubroot disease resistance in B. juncea, we conducted a genome-wide analysis on this vegetable, and we analyzed the phylogenetic evolution and gene structure of the MAPK gene family in mustard. The 66 BjuMAPK genes identified by screening the whole genome sequence of B. juncea were unevenly distributed on 17 chromosomes. At the genomic scale, tandem repeats led to an increase in the number of MAPK genes in B. juncea. It was found that members of the same subfamily had similar gene structures, and there were great differences among different subfamilies. These predicted cis-acting elements were related to plant hormones, stress resistance, and plant growth and development. The expression of BjuMAPK02, BjuMAPK15, BjuMAPK17, and BjuMAPK19 were down-regulated or up-regulated in response to P. brassicae infection. The above results lay a theoretical foundation for further studying the functions of BjuMAPK genes in B. juncea in response to the biotic stress caused by clubroot disease.

Objective:We aimed to analyse the trend of incidence and mortality of stomach cancer in Shandong province from 2012 to 2022 and predict the development trend from 2023 to 2030.Methods:Data on incidence and mortality of stomach cancer in Shandong province from 2012 to 2022 were obtained from Shandong Cancer Registry. The incidence, age-specific incidence, mortality and age-specific mortality in different years, sexes and urban and rural areas were calculated, the rates were standardized based on the age composition of the Chinese standard population in 2000. The average annual percent change (AAPC) of incidence and mortality was calculated using Joinpoint software. The Bayesian age-period-cohort model was used to predict the trend of stomach cancer incidence and mortality from 2023 to 2030.Results:From 2012 to 2022, the stomach cancer age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) showed a decreasing trend. The ASIR decreased from 27.47/100 000 in 2012 to 16.06/100 000 in 2022 (AAPC=-5.10%, P＜0.001), and the ASMR decreased from 17.69/100 000 to 11.09/100 000 (AAPC=-5.52%, P＜0.001). The ASIR and ASMR of male, female, urban and rural population also showed downward trends. The incidence and mortality rates of men were always higher than those of women, and the difference between urban and rural areas is gradually narrowing. In 2022, the ASIR (16.09/100 000 in urban and 16.03/100 000 in rural) and the ASMR (11.10/100 000 in urban and 11.08/100 000 in rural) of stomach cancer between urban and rural areas were nearly identical. The Bayesian age-period-cohort model predicted that the ASIR of stomach cancer in Shandong would further decrease from 2023 to 2030 (AAPC=-0.51%, P=0.001), but the change tended to be smooth. The incidences in male (AAPC=-1.46%, P=0.010) and rural areas (AAPC=-1.21%, P＜0.001) were still expected to have a little room for decline. The trend of incidences in female and urban areas were not statistically significant. The trend of mortality was consistent with the incidence. Conclusions:The stomach cancer incidence and mortality in Shandong shows a decreasing trend and it is expected to decrease further by 2030. However, the trend tends to be smooth, and the disease burden should be reduced as early as possible for high-risk population and high-risk factors of stomach cancer.

Objective:To describe the trend of mortality and death spectrum in Shandong Province from 1970 to 2021 and provide basis for the targeted disease prevention and control.Methods:The data were collected from the death registration reports of Shandong and 3 national retrospective surveys of death causes in Shandong. The change in levels of overall and specific deaths in Shandong in different years were analyzed based on mortality rate, age-standardized mortality rate and constituent ratio of cause of death, differential decomposition was used to quantify the contribution of demographic and non-demographic factors to changes of mortality.Results:The crude mortality rate in residents in Shandong was basically stable from 1970 to 2021, and the mortality rate during 2020-2021 (732.73/100 000) was slightly higher than that during 1970-1974 (671.98/100 000). While the standardized mortality rate decreased significantly, and the mortality during 2020-2021 (183.39/100 000) decreased by 67.71% compared with that during 1970-1974 (568.00/100 000). The negative increase of population factors and the positive decrease of non-population factors reacted each other, so the mortality was relatively stable. Cardiac-cerebrovascular disease was always the leading cause of death, but the constituent ratio of death increased rapidly from 19.70% during 1970-1974 to 54.72% during 2020-2021. The rank in the causes of death changed from the fourth (11.46%) to the second (25.70%) for malignant tumor, from the seventh (5.85%) to the third (5.59%) for injury, from the second (12.87%) to the fourth (4.99%) for chronic respiratory diseases, from the third (12.27%) to the tenth (0.42%) for infectious diseases. The standardized mortality rates of the main causes of death decreased at different degrees, the standardized mortality rates of obstetrical disease, infectious disease, gastrointestinal disease and chronic respiratory disease decreased by more than 50.00%. The age distribution of deaths and the death spectrum in different age groups and in urban-rural populations changed significantly. During 2020-2021, the proportion of deaths in young people aged 0-14 years was 0.54%, which was 97.05% lower than that during 1970-1974, while the proportion of deaths in the elderly aged ≥75 years was 55.14%, which was 55.75% higher than that during 1970-1974. The rank of infectious diseases in the causes of death descended significantly in all age groups, but the ranks of injury, neuropsychiatric disease and malignant tumor rose significantly in adolescents, and the ranks of endocrine nutrition and metabolic disease rose in middle-aged and elderly people. The difference of death spectrum between urban area and rural area became less obvious and the main death causes in urban and rural residents were basically the same during 2020-2021.Conclusions:The death spectrum of residents in Shandong changed significantly. Chronic and non-communicable diseases, especially cardiac-cerebrovascular disease and malignant tumor, should be the focus in disease control and prevention. The prevention and control of diseases in Shandong made remarkable achievement during 1970-2021. However, in the context of population ageing, it is suggested to strengthen the treatment, prevention of diseases and injuries related to the health of the elderly and elderly health care in the future.

Objective:To conduct a phased summary and analysis of the operation and quality control (QC) of the first human milk bank (HMB) in East China over a ten-year period.Methods:Data on the operation of the HMB at Women's Hospital of Nanjing Medical University, characteristics of donors and recipients, clinical application of donated milk, and operational costs from August 1, 2013, to July 31, 2023, were collected, organized, analyzed, and described. Quality and safety management of the HMB began in 2016, with QC measures implemented. Chi-square tests were used to compare data related to the operation of the HMB, donors, and recipient infants before QC (2013-2015) and after QC (2016-2023). Results:Over the ten-year period since its establishment, the HMB received donor human milk (DHM) from 1 974 donors, totaling 9 390.41 liters. The qualification rate of donors was 86.47% (1 707/1 974), with a qualification rate of DHM of 98.01% (9 203.21/9 390.41) and 21 757 donation instances, with the highest individual donation count reaching 195 times. In the past 10 years, due to the epidemic of the new coronavirus in 2020, the number of milk donors, the amount of DHM and the total number of milk donations decreased significantly, but the amount of DHM per capita and the number of milk donations per capita showed a continuous upward trend. Compared to the period before QC, the qualification rate of donors [96.75% (1 253/1 295) vs. 66.86% (454/679), χ 2=340.33, P<0.001] and the qualification rate of DHM [98.19% (8 366.76/8 521.08) vs. 96.22% (836.45/869.33), χ 2=16.33, P<0.001] both improved after QC. A total of 11 197 recipients received 6 615.38 liters of DHM, with a utilization rate of 71.88% (6 615.38/9 203.21). The current operation mode of the HMB is "voluntary donation, free use". Over ten years, the costs for consumables, testing, labor, energy, and fixed assets amounted to 9.36 million CNY, with an operational cost of 996.32 CNY per liter (9.36 million/9 390.41 L) and approximately 1.00 CNY per milliliter of DHM. Conclusions:The hospital's HMB has been operating stably for ten years, and abundant DHM benefits many newborns. QC measures have effectively increased the qualification rates of both donors and DHM, providing better nutritional support for the treatment of critically ill infants. However, the operational costs of the HMB are relatively high, necessitating the exploration of an operational model suitable for China's national conditions.

Insulin-like growth factor-1 receptor (IGF-1R) has been made an attractive anticancer target due to its overexpression in cancers. However, targeting it has often produced the disappointing results as the role played by cross talk with numerous downstream signalings. Here, we report a disobliging IGF-1R signaling which promotes growth of cancer through triggering the E3 ubiquitin ligase MEX3A-mediated degradation of RIG-I. The active β-arrestin-2 scaffolds this disobliging signaling to talk with MEX3A. In response to ligands, IGF-1Rβ activated the basal βarr2 into its active state by phosphorylating the interdomain domain on Tyr64 and Tyr250, opening the middle loop (Leu130‒Cys141) to the RING domain of MEX3A through the conformational changes of βarr2. The models of βarr2/IGF-1Rβ and βarr2/MEX3A could interpret the mechanism of the activated-IGF-1R in triggering degradation of RIG-I. The assay of the mutants βarr2^Y64A and βarr2^Y250A further confirmed the role of these two Tyr residues of the interlobe in mediating the talk between IGF-1Rβ and the RING domain of MEX3A. The truncated-βarr2 and the peptide ATQAIRIF, which mimicked the RING domain of MEX3A could prevent the formation of βarr2/IGF-1Rβ and βarr2/MEX3A complexes, thus blocking the IGF-1R-triggered RIG-I degradation. Degradation of RIG-I resulted in the suppression of the IFN-I-associated immune cells in the TME due to the blockade of the RIG-I-MAVS-IFN-I pathway. Poly(I:C) could reverse anti-PD-L1 insensitivity by recovery of RIG-I. In summary, we revealed a disobliging IGF-1R signaling by which IGF-1Rβ promoted cancer growth through triggering the MEX3A-mediated degradation of RIG-I.

Objective:To investigate the clinical efficacy of laparoscopic eversion fixation of cyst wall in the treatment of simple hepatic cyst.Methods:The clinical data of 27 patients with simple hepatic cyst who underwent laparoscopic cyst eversion fixation in Department of Hepatobiliary Surgery, the First Affiliated Hospital of Henan University of Science and Technology from January 2017 to December 2020 were retrospectively analyzed. There were 8 males and 19 females, aged (60.6±9.0) years. Methods of operation, operation time, pathological results, incisional pain, peritonitis, bleeding or infection in the sac were analyzed. Recurrence was followed up by outpatient or telephone review.Results:Laparoscopic eversion fixation of cyst wall was successfully performed in all patients. Twelve cases (44.4%) were fixed in the falciform ligament, and 15 cases (55.6%) were fixed on the liver surface. The operative time was (119.3±44.3) min. The histopathologic results of the capsular wall were all fibrous connective tissue coated with endothelial cells, and no tumor cells were found. After the operation, 25 cases (92.6%) of light clear cyst fluid were not cultured for bacteriology, and 2 cases (7.4%) of turbid cyst fluid bacteriology culture was negative. There were 11 cases (40.7%) with right upper abdominal incision pain on the first day after surgery, and the pain disappeared after proper treatment without bile leakage, peritonitis, bleeding or infection. All patients were followed up for 18 to 36 months, with a median follow-up time of 24 months, and no cyst recurrence was reported.Conclusion:Laparoscopic eversion fixation of cyst wall is a good method for the treatment of simple hepatic cyst.

ObjectiveTo investigate the mechanism of Huazhuo Jiedu Huoxue Tongluo prescription in alleviating cerebral ischemia-reperfusion injury via regulating nerve cell autophagy based on c-Jun N-terminal kinase（JNK）signaling pathway . MethodSixty SD rats were randomly divided into 6 groups： sham group， middle cerebral artery occlusion/reperfusion （MCAO/R） group （model group）， Huazhuo Jiedu Huoxue Tongluo prescription group ［traditional Chinese medicine （TCM） group（25.0 g·kg^-1）］， JNK inhibitor SP600125 （SP） group（5 mg·kg^-1）， TCM+SP group and JNK agonist Anisomycin （Ani） group（15 mg·kg^-1）. After 24 h of modeling， TCM group and TCM+SP group were given TCM decoction （ig） for 3 consecutive days， and the other groups were given equal volume of normal saline （ig）. Neurological deficit was evaluated by neurological function score and cerebral infarct volume was determined by 2，3，5-triphenyltetrazole chloride （TTC） staining. Hematoxylin-eosin （HE） staining and Nissl staining were used to observe the structural changes of brain tissue and the damage of neurons， respectively. Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay （TUNEL） was performed to detect cell apoptosis. The ultrastructure of autophagosomes was observed by transmission electron microscope. Western blot was employed to detect the protein expressions of microtubule-associated protein 1 light chain 3A/B （LC3A/B）， autophagy related 5 （Atg5）， the ortholog of yeast Atg6 （Beclin1）， p62， B-cell lymphoma 2 （Bcl-2）， JNK， phosphorylated （p）-JNK and c-Jun in brain tissue. The mRNA expressions of LC3A/B， Beclin1， p62， Atg5， Bcl-2， JNK and c-Jun were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the sham group， the model group had elevated neurological deficit score （P<0.05）， enlarged cerebral infarct volume （P<0.05）and typical infarction manifestations formed in hippocampal region and its surrounding brain tissue. In addition， there were a large number of neuronal cell degeneration， necrosis， liquefaction， nucleus pyknosis and deep staining， and inflammatory cell infiltration in the cortex in the model group， and severe swelling of mitochondria， lysosomes， autophagosomes and autophagolysosomes were clearly seen under electron microscope. TUNEL positive cells were increased （P<0.05）， and cell apoptosis was severe. The nuclear membrane and nucleolus of neurons in brain tissue were blurred with discontinuous processes， and Nissl bodies in cytoplasm were stained light with reduced number. Western blot revealed that the model group had up-regulated protein expressions of LC3A/B， Beclin1， Atg5， JNK， p-JNK and c-Jun in brain tissue （P<0.05）， while down-regulated protein expressions of p62 and Bcl-2 （P<0.05）as compared with the sham group. Real-time PCR indicated that the mRNA expressions of LC3A/B， Beclin1， Atg5， JNK and c-Jun in the model group were higher （P<0.05） while the mRNA expressions of p62 and Bcl-2 were lower （P<0.05） than those in the sham group. Compared with the conditions in model group， the neurological deficit scores of TCM， SP and TCM+SP groups were lowered （P<0.05）， and the cerebral infarct volume was reduced （P<0.05）， with improved pathological status of brain tissue， especially in the TCM group. Furthermore， there were abundant and basically normal mitochondrial cristae， slightly dilated endoplasmic reticulum， slightly swollen golgi apparatus， slightly fused nuclear membrane， and few visible lysosomes， autophagosomes and autophagolysosomes. TUNEL positive cells were decreased （P<0.05）， displaying reduced apoptosis， especially in the TCM group. The nucleolus and nuclear membrane of neurons in brain tissue were discernible， and Nissl bodies in cytoplasm was reduced to a certain degree as compared with those in the model group. Western blot showed a decrease in the protein expressions of LC3A/B， Beclin1， Atg5， JNK， p-JNK and c-Jun in the TCM group ，the SP group，and the TCM+SP group（P<0.05），while an increase in the protein expressions of p62 in the TCM group and SP group（P<0.05），and an increase in the protein expressions of Bcl-2 in the TCM group and TCM+SP group. By Real-time PCR， the mRNA expressions of LC3A， LC3B， Beclin1， Atg5， JNK and c-Jun had a down-regulation（P<0.05） while the mRNA expression of p62 a up-regulation in the TCM group ，the SP group，and the TCM+SP group（P<0.05），and the mRNA expression of Bcl-2 a up-regulation in the TCM group and the TCM+SP group（P<0.05）.Scores of the Ani group were raised （P<0.05）， and infarct volume was increased significantly， with aggravated neuronal cell necrosis and obvious inflammatory infiltration. Moreover， there were neuronal nuclear membrane fusion with abnormal protrusion， increased heterochromatin aggregation in edge， severe mitochondrial swelling， endoplasmic reticulum expansion， increased lysosomes， increased intracytoplasmic vesicles， and visible autophagosomes and autophagolysosomes. TUNEL positive cells were increased （P<0.05）， representing severe apoptosis. The number of Nissl bodies dropped with light staining， and the nucleolus and nuclear membrane were blurred. Real-time PCR found that the mNRA expressions of Atg5， c-Jun， JNK were up-regulated （P<0.05），while Beclin1， p62， Bcl-2 were were down-regulated in the Ani group （P<0.05）. Compared with the TCM group and SP group，the protein expressions of LC3A/B， Beclin1， Atg5， JNK， p-JNK， c-Jun were decreased，and p62， Bcl-2 were increased in the Ani group（P<0.05）. Compared with the TCM group，the mRNA expressions of JNK mRNA had a down-regulation in the SP group and TCM+SP group，while LC3A， LC3B， Atg5， c-Jun， JNK had an up-regulation（P<0.05） and Bcl-2 had a down-regulation in the Ani group（P<0.05）. Compared with the SP group，the mRNA expressions of Atg5， c-Jun， JNK had an up-regulation（P<0.05）， and Beclin1， p62， Bcl-2 had a down-regulation in the Ani group（P<0.05）. ConclusionHuazhuo Jiedu Huoxue Tongluo prescription significantly up-regulates the protein and mRNA expressions of LC3A/B， Beclin1， Atg5， JNK， p-JNK and c-Jun， and down-regulates the protein and mRNA expressions of p62 and Bcl-2， suggesting that the prescription can inhibit autophagy through JNK signaling pathway to reduce ischemia/reperfusion injury in rats.

The WUSCHEL related-homeobox (WOX) family is one of the plant-specific transcription factor families, playing important roles in plant growth and development. In this study, 51 WOX gene family members were identified from the genome data of Brassica juncea by searching and screening with HUMMER, Smart and other software. Their protein molecular weight, amino acids numbers, and isoelectric point were analyzed by using Expasy online software. Furthermore, bioinformatics software was used to systematically analyze the evolutionary relationship, conservative region, and gene structure of the WOX gene family. The mustard WOX gene family was divided into three subfamilies: ancient clade, intermediate clade, and WUS clade/modern clade. Structural analysis showed that the type, organization form and gene structure of the conservative domain of WOX transcription factor family members in the same subfamily were highly consistent, while there was a certain diversity among different subfamilies. 51 WOX genes are distributed unevenly on 18 chromosomes of mustard. Most of the promoters of these genes contain cis acting elements related to light, hormone and abiotic stress. Using transcriptome data and real-time fluorescence quantitative PCR (qRT-PCR) analysis, it was found that the expression of mustard WOX gene was spatio-temporal specific, among which BjuWOX25, BjuWOX33, and BjuWOX49 might play an important role in the development of silique, and BjuWOX10, BjuWOX32, and BjuWOX11, BjuWOX23 respectively might play an important role in the response to drought and high temperature stresses. The above results may facilitate the functional study of mustard WOX gene family.
