Objective:To analyze the effects of shift work on the renal function of oil workers and investigate whether there is a measured response relationship between shift work and renal dysfunction.Methods:In this study, oil workers who participated in physical examinations at the North China Oilfield Downhole Hospital were selected as the study subjects, and the physical examinations as well as questionnaires of the study subjects in 2017 and 2018 were collected as the baseline data, which included blood biochemical indexes, socio-demographic characteristics, history of life behaviors, occupational exposures, and occupational histories. Three follow-up surveys were subsequently conducted in April 2019, April 2020, and January 2021. The presence of renal dysfunction in the study population was determined based on the glomerular filtration rate tested at the medical examination hospital. The exposure of the study subjects to shift work was assessed using the weighted shift index (WSI), the relationship between different levels of shift work and renal dysfunction was analyzed using Cox regression, and the measure of WSI and renal dysfunction was explored by restricted cubic spline (RCS). response relationship.Results:A total of 2292 study participants were included in this study, and the prevalence density of renal dysfunction was 87.44 k/year, of which the prevalence of renal dysfunction in females (30.31%), those with per capita monthly income <2, 000 yuan (27.00%), those who consume alcohol (27.10%), those who are hypertensive (23.05%), those who are exposed to high temperatures (27.37%), those who are exposed to organic solvents (30.42%), and those who are engaged in shift work (25.87%) were to be found had a higher prevalence of renal dysfunction ( P<0.05). After correcting for age, sex, and other risk factors, there was a nonlinear association between intensity of shift work and renal dysfunction, with a hazard ratio ( HR) of 1.29 (95% CI: 0.98-1.59) for the development of renal dysfunction in petroleum workers for shift work performed at higher intensities, and moderate intensity of exposure to shift work reduced the risk of renal dysfunction in petroleum workers ( HR=0.54 with a 95% CI: 0.39-0.75, P<0.001) . Conclusion:Prolonged shift work increases the risk of renal dysfunction in oil workers, and the occurrence of renal dysfunction in oil workers is influenced by multiple factors.

Objective:To investigate the clinical effect of ultrasound bone knife bone window technique combined with viscous bone in mandibular cysts and its impact on postoperative bone defect repair.Methods:60 patients with mandibular cysts who visited our hospital from January 2024 to June 2024 were selected as the study subjects,they were randomly divided into control group(30 cases)and experimental group(30 cases).The control group underwent traditional scraping surgery(without the use of bone defect repair materials).The experimental group used ultrasound bone knife bone window technology combined with adhesive bone treatment.The surgical time,postoperative visual pain simulation(VAS)score,intraoperative blood loss,postoperative swelling degree,and incidence of postoperative complications between the two groups were observed and compared.Bone defect repair was evaluated by cone beam computed tomography(CBCT)at 3 and 6 months postoperatively.Results:There was no significant difference in surgical time,intraoperative blood loss,postoperative swelling degree,and incidence of postoperative complications between the two groups(P＞0.05).The VAS scores of both groups at 3 and 7 d postoperative were lower than those at 1 d postoperative(P＜0.05),and the VAS score at 7 d postoperative was lower than that 3 d postoperative(P＜0.05).The VAS scores in the experimental group were significantly lower than those in the control group at 1,3 and 7 d postoperative(P＜0.05).The HU values and bone repair area ratio in the experimental group at 3 and 6 months postoperative were significantly higher than those in the control group(P＜0.05),and the HU values and bone repair area ratio in the control group and experimental group at 6 months postoperative were significantly increased compared to those at 3 months postoperative(P＜0.05).Conclusion:The combination of ultrasound bone knife bone window technology and adhesive bone treatment for mandibular cysts can significantly reduce postoperative pain,accelerate bone defect repair,and improve bone density and repair quality.Compared with traditional scraping surgery,the use of sticky bone has significant advantages in postoperative bone regeneration and does not significantly increase the risk of complications,making it of high clinical application value.

Stroke is one of the main diseases that threaten human health,including ischemic stroke and hemorrhagic stroke,with the former being the main cause.The important pathogenesis of ischemic stroke includes neuroinflammation,oxidative stress,and excitatory toxic damage,and neuroinflammation plays an impor-tant role in the pathogenesis and rehabilitation process of ische-mic stroke.Microglia are inherent immune cells in the central nervous system,which monitor the site of injury and respond to the immune response as soon as a stroke occurs.The activated microglia are mainly polarized into pro-inflammatory M1 type and anti-inflammatory M2 type.The latter improves neurological dys-function by inhibiting neuroinflammation,promoting neuronal re-generation and myelin repair,and maintaining the integrity of the blood-brain barrier.It suggests that it may be a potential target for treating ischemic stroke by combating acute phase injury and promoting chronic phase rehabilitation.Precise regulation of M1/M2 activation has important therapeutic value in cerebral protection in ischemic stroke.This article focuses on the role of M2 microglia in ischemic stroke and the mechanism of various drugs or acupuncture and moxibustion therapy regulating the transformation of microglia into M2 type,in order to provide theo-retical basis for clinical treatment of stroke and new drug devel-opment.

Objective To investigate the characteristics of Chinese medicine syndromes and the possible metabolic substance basis of spontaneously hypertensive rat(SHR).Methods 10-week-old SPF SHR and WKY of the same strain were divided into SHR group and WKY group with 8 rats in each group.The general state,temperament,peripheral vascular filling,tongue characteristics,diet,water intake,urine and feces volume and characteristics,blood pressure,heart rate,respiratory rate,pain threshold,and open field behavior of SHR rats were observed and tested comprehensively to identify the possible syndrome types of Chinese medicine.At the same time,liquid chromatography tandem mass spectrometry was used to analyze non-targeted serum metabolites to preliminarily reveal the material basis of blood pressure elevation and Chinese medicine syndrome manifestations.Results Compared with WKY group,the scores of dark yellow hair color,irritable degree and peripheral capillary filling were higher in SHR group(P＜0.0001).Red tongue color,dry tongue,little body fluid;24 h diet and water intake,urine volume and fecal volume were less(P＜0.05),fecal water content was lower(P＜0.001);systolic blood pressure(SBP),diastolic blood pressure(DBP),mean arterial pressure(MAP),heart rate(HR)and respiratory rate(RR)were significantly higher(P＜0.05);Lower pain threshold(P＜0.0001);The open field experiment shows that the moving distance and residence time of the edge are longer(P＜0.001).Serum non-targeted metabolomics result showed that,compared with WKY group,the SHR group had 114 metabolites with significant differences(P＜0.05).These differential metabolites were mainly lipids and lipid-like molecules(40.35％),organic acids and derivatives(22.8％),and organoheterocyclic compounds(15.79％).A total of 25 metabolic pathways were identified by KEGG enrichment analysis.Further differential abundance analysis showed that 16 pathways were activated,only 4 pathways were inhibited,and 5 pathways were not significantly changed.The glutamatergic synapse and GABAergic synapse were activated,while the serotonergic synapse was inhibited.Conclusions The symptoms of SHR include impatience and irritability,peripheral vascular dilation and collateral circulation formation,bulbar conjunctival congestive swelling,red tongue coloration,a dry tongue,constipation,red-yellow urine of low volume,and a rapid heart rate and high respiratory rate.All these suggest that SHR is a syndrome of hypertension with hyperactivity of liver-yang.The material basis of SHR is not only related to lipid,amino acid,and carbohydrate metabolism disorders,but also may be related to metabolic disorders of glutaminergic,GABAergic,and serotonergic neural pathways.

Malonylation is an important post-translational modification of proteins.In this work,a comprehensive malonylation proteomics study on hepatocellular carcinoma(HCC)tumorous and non-tumorous tissues using antibody enrichment combined with high performance liquid chromatography-mass spectrometry for discovery of early diagnostic biomarkers or potential new drug targets of HCC was performed.A total of 1299 malonylated peptides containing 1064 malonylated sites were identified from HCC tissues,corresponding to 511 malonylated proteins.Quantitative results showed that 56 and 80 malonylated proteins were up-regulated and down-regulated in HCC tissues,including 60 and 101 malonylated sites,respectively.Kyoto encyclopedia of genes and genomes(KEGG)pathway analysis showed that these differentially modified proteins were involved in various important pathways such as metabolic pathways,fatty acid degradation,and glycolysis/gluconeogenesis.As a key enzyme in glycolysis/gluconeogenesis,phosphoenolpyruvate carboxykinase 1(PCK1)was malonylated at lysine 244(K244)and the malonylation was only detected in HCC tumorous tissues.More importantly,the K244 site served as a binding site for Mn2+and highly conserved across different species.Therefore,it could speculate that the malonylation of K244 would affect its activity and played a role in liver cancer by affecting its binding with Mn2+,which requied further verification through site mutation experiments.Western blot analysis by malonylation pan antibody showed that the malonylation level reduced markedly in HCC tumorous tissues compared with adjacent non-tumorous tissues,which was consistent with mass spectrometry data.In addition,the proliferation and invasion of PLC/PRF/5 cell was significantly inhibited and protein malonylation level was increased obviously when treated with sodium malonate.All the evidence indicated that protein malonylation played an important role in HCC pathogenesis,and its molecular mechanism deserved further investigation.Furthermore,the 136 differentially malonylated proteins provided rich source of candidate targets for further research on HCC pathogenesis.

Objective:To investigate the longitudinal patterns and influencing factors of platelet counts among healthy adults in Sichuan Province from 2010 to 2021, and to inform the establishment of region-specific reference intervals for platelet counts.Methods:This study is a retrospective study. A total of 7 808 healthy adults who underwent annual physical examinations at West China Hospital, Sichuan University, between January 2010 and December 2021 were included. All participants were permanent Chengdu residents and completed consecutive complete blood count tests. Group-based trajectory modeling (GBTM) was used to identify distinct trajectories of platelet count over the ten-year period. One-way analyses were then conducted to compare baseline demographic characteristics (sex and age) among the different trajectory groups.Results:Among 7 808 participants, 4 589 (58.8%) were male and 3 219 (41.2%) were female. Four platelet count trajectories were identified by GBTM: steadily increasing group [27.4% (2 139/7 808)], early increase-plateau group [44.1% (3 445/7 808)], early decrease-subsequent increase group [5.4% (422/7 808)], and steadily decreasing group [23.1% (1 802/7 808)], with an average growth rate of 3.3%, 1.6%, 0.7%, and -0.6%, respectively. There were statistically significant differences in both sex and age distributions among the four trajectory groups. Sex-distribution differed significantly across the four trajectory groups ( χ2=73.3, P<0.001). The male proportions in the four trajectory groups were 59.6% (1 275/2 139), 62.8% (2 165/3 445), 48.1% (203/422), and 52.5% (946/1 802), respectively. The baseline ages were 45 (36, 55), 43 (35, 53), 50 (40, 60), and 47 (39, 58) years, respectively (H=121.0, P<0.001). Conclusions:Healthy adults in Sichuan Province exhibit four longitudinal trajectories of platelet counts: steadily increasing, early increase-plateau, early decrease-subsequent increase, and steadily decreasing. The two trajectories characterized by rising platelet counts (steadily increasing group and early increase-plateau group) exhibited higher male predominance and lower median ages, whereas the early decrease-subsequent increase group and the steadily decreasing group exhibited lower male proportions and higher median ages. Therefore, while establishing reference intervals and developing health management strategies for platelet counts, it is essential to account for the sex, age characteristics and the population′s dynamic changes.
