Objective To investigate the therapeutic effect of gabapentin combined with hemoperfusion on skin pruritus in the patients on maintenance hemodialysis(MHD).Methods A total of 72 patients with MHD complicating moderate to severe skin itching treated in Lianyungang Municipal Oriental Hospital from January 2023 to March 2024 were selected as the study subjects and divided into the observation group and control group by the random number table method,36 cases in each group.On the basis of symptomatic treat-ment,the control group was given hemodialysis 3 times a week and hemoperfusion twice a month;on the basis of the control group,the observation group orally took 1 gabapentin capsule every night,and the patients in the two groups continued to be treated for 12 weeks.The visual analogue scale(VAS)score,Pittsburgh Sleep Quality Index(PSQI)score,molecular toxin level and calcium and phosphorus metabolism were evaluated be-fore treatment,in 4,12 weeks after treatment respectively,and the occurrence of adverse reactions during treatment in the two groups was observed.Results After 4 weeks and 12 weeks of treatment,the VAS and PSQI scores of the observation group were decreased compared with those before treatment,moreover the scores of the observation group were lower than those of the control group in the same period,and the differ-ences were statistically significant(P<0.05);the VAS and PSQI scores after 4 weeks of treatment in the control group were decreased compared with those before treatment,but the difference was not statistically significant(P>0.05);and the VAS and PSQI scores after 12 weeks of treatment in the control group were decreased compared with before treatment,and the difference was statistically significant(P<0.05).After 4 weeks of treatment,the levels of Scr,BUN and β2-MG in the two groups were decreased compared with those before treatment,but the differences were not statistically significant(P>0.05);after 12 weeks of treatment,the levels of Scr,BUN and β2-MG in the two groups were decreased compared with those before treatment and after 4 weeks of treatment,and the differences were statistically significant(P<0.05),but there was no sta-tistically significant difference between the two groups(P>0.05).After 4 weeks of treatment,there was no statistically significant difference in the levels of blood Ca,P and iPTH between the two groups compared with before treatment(P>0.05);after 12 weeks of treatment,except for blood Ca,the levels of blood P and iPTH in the two groups were decreased compared with those before treatment and in 4 weeks of treatment(P<0.05),and the differences were statistically significant(P<0.05),but there was no statistical difference be-tween the two groups(P>0.05).There were no adverse reactions in the control group,and there were 3 cases of drowsiness,1 case of fatigue and 1 case of dizziness at the beginning of treatment in the observation group.The symptoms were mild without treatment and spontaneously relieved in about 1 week.Conclusion Gabap-entin combined with hemoperfusion could quickly and effectively alleviate the itchy symptoms of skin,improve the sleep quality,reduce the uremic toxin levels,and improve the calcium and phosphorus metabolism in MHD patients,with few adverse reactions,and the patients are easy to tolerate.

Objective:To explore the mechanism of resveratrol in treatment of sleep disorders in mice based on network pharmacology and experimental verification.Methods:Resveratrol targets were obtained through traditional Chinese medicine systems pharmacology database and analysis platform, Swiss Target Prediction and SuperPred databases. Targets related to sleep disorders were collected from the gene expression omnibus, GeneCards, DrugBank, OMIM, CTD and MalaCards databases. Cytoscape 3.8.0 software was used to identify the core targets of resveratrol in treatment of sleep disorders via protein-protein interaction analysis. Gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analyses were performed, and AutoDockvina software was used to conduct molecular docking between the top five core targets and resveratrol. Thirty ICR female mice were selected and divided into a control group, a model group, and low-, medium- and high-dose (10, 20, and 30 mg/kg) resveratrol groups according to the random number table method, with 6 mice in each group. Resveratrol was dissolved in 0.9% sodium chloride aqueous solution and 3% dimethyl sulfoxide. For mice in the low-, medium-, and high-dose resveratrol groups, 10, 20, and 30 mg/kg of resveratrol solution were intraperitoneally injected, respectively. The mice in the control group and the model group were intraperitoneally injected with 10 ml/kg of 0.9 % sodium chloride aqueous solution and 3 % dimethyl sulfoxide. Each group was injected once a day for 7 consecutive days. After 7 days of administration, a mouse sleep deprivation model was constructed using an improved multi platform water environment method. The spatial recognition and memory abilities of mice were tested using the Y-maze experiment, and the mRNA and protein relative expression levels of estrogen receptor 1 (ESR1) and B-cell lymphoma-2 (Bcl-2) were detected using real-time reverse transcription-PCR and Western blotting, respectively. Comparisons were made using t-test. Results:There were 47 common targets between resveratrol and sleep disorders, and the top five core targets were ESR1, Bcl-2, cytochrome P450, family 1, subfamily A, polypeptide 1 (CYP1A1), cytochrome P450, family 2, subfamily A, polypeptide 4 (CYP3A4) and cytochrome P450, family 1, subfamily B, polypeptide 1 (CYP1B1). GO enrichment analysis revealed that resveratrol in treatment of sleep disorders was mainly related to the regulation of unsaturated fatty acid metabolic processes, secondary metabolic processes, and responses to exogenous stimuli. KEGG pathway analysis showed that resveratrol acted mainly through pathways involving chemical carcinogenic-DNA adducts, cytochrome P450 metabolism of exogenous substances and estrogen signaling pathways. Molecular docking results indicated that resveratrol had strong binding affinity with ESR1, Bcl-2, CYP1A1, CYP3A4 and CYP1B1, with binding energies of ?31.92, ?27.72, ?34.44, ?34.02 and ?31.92 kJ/mol, respectively. In vivo experiments results demonstrated that the novel arm residence time in the low-, medium- and high-dose resveratrol groups [(52±5, 55±7, and 61±9) s] was higher than that in the model group [(45±4) s] ( P<0.05 or 0.01), and the percentage of spontaneous alternation [(53±4)%, (57±5)%, and (65±7)%] was higher than that in the model group [(47±3)%] ( P<0.05 or 0.01). The relative expression levels of ESR1 mRNA (0.42±0.10, 0.49±0.11, and 0.58±0.10) were higher than those in the model group (0.29±0.06) ( P<0.05 or 0.01). The relative expression levels of Bcl-2 mRNA (0.56±0.07, 0.65±0.10, and 0.77±0.11) were higher than those in the model group (0.44±0.08) ( P<0.05 or 0.01). Similarly, the relative expression levels of ESR1 protein (0.32±0.02, 0.50±0.02, and 0.62±0.02) were higher than those in the model group (0.24±0.01) ( P<0.05 or 0.01). The relative expression levels of Bcl-2 protein (0.45±0.08, 0.69±0.06, and 0.72±0.06) were higher than those in the model group (0.17±0.04) ( P<0.05 or 0.01). Conclusions:Resveratrol exerts therapeutic effects on sleep disorders by acting on ESR1 and Bcl-2.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

ObjectiveTo genotype Oncomelania hupensis， based on microsatellites， in different snail-bearing environments in Jiaxing City， Zhejiang Province， for population genetics analysis in order to explore the reasons and influencing factors for the existence or proliferation of snails and to provide scientific basis for effective monitoring and control of snails. MethodsA total of 90 snail samples from three populations were collected in Yaobang Village （YB） and Sanxing Village （SX） in Pinghu City， and Yunhe Farm （YH） in Xiuzhou District， all were selected for snail checking in key snail habitats of Jiaxing City in 2022. DNA of the snails was genotyped and analyzed for population genetics using nine microsatellite loci. ResultsA total of 84 alleles were observed， and the mean number of alleles （Na） was 7.889， 5.667， and 3.778 for YB， SX， and YH respectively； the number of effective alleles （NeA） was 4.807， 3.329， and 2.294， respectively； and the coefficients of inbreeding （F_IS） were 0.400， 0.377， and 0.493， respectively. Under the Infinite Allele Model （IAM）， the SX and YH might have a recent bottleneck. The NEstimator and LDNe software calculated effective population sizes （Ne） were above 31.9. AMOVA analysis showed that the variation of snails in the three populations mainly existed among individuals， accounting for 41.4% of the total variation. The value of the index of genetic differentiation between populations （F_ST） was 0.286， indicating a high degree of genetic differentiation. The results of the principal component analysis and phylogenetic tree were consistent， and the three populations were divided into two lineages， YB and SX were one lineage， and YH belonged to another independent lineage. Population history and dynamics analysis showed that the gene flow of the three populations was insufficient， population divergence history indicated that YH might have diverged from SX first， and YB was produced by the contact fusion of SX and YH. ConclusionThe genetic diversity of snail populations in Jiaxing City is generally low， and the snail populations are unstable， with a great degree of genetic differentiation and insufficient gene flow among populations. This study can provide a basis for evaluating the effectiveness of the control of the snail as well as monitoring the trend of the spread of the snail.

Objective:To explore the mechanism of action of Coptis chinensis in the treatment of dental caries using a network pharmacology approach and animal experiments. Methods:The active ingredients of C. chinensis and their targets were screened by the traditional Chinese medicine systems pharmacology (TCMSP) database and analysis platform, and the targets were searched online through the GeneCards database. The intersecting targets of C. chinensis and dental caries were screened at Venny 2.1, and the intersection targets were analyzed online for protein-protein interaction analysis and gene ontology (GO) and kyoto encyclopedia of genes and genomics (KEGG) enrichment. Then, Cytoscape was used to create a "component-target-pathway" network diagram. Rats were randomly divided into the model group and the C. chinensis group to establish a rat model of dental caries. Rats in the model group were repeatedly rubbed with a cotton ball soaked in 150 μl of 0.9% NaCl solution for 5 min, and rats in the C. chinensis group were repeatedly rubbed with a cotton ball soaked in C. chinensis (5.8 mg of C. chinensis in 150 μl of 0.9% NaCl solution) for 5 min. The two groups of rats were treated once a week for four consecutive weeks. The number of Streptococcus mutans colonies was counted, and serum serine/threonine protein kinase 1 (AKT1), JUN, interleukin-6 (IL-6), tumor necrosis factor (TNF), and B-cell lymphoma-2 (Bcl-2) were detected by enzyme immunoassay. Results:A total of 11 active ingredients in C. chinensis were found, which regulate multiple molecular pathways by intervening in 54 targets, thereby treating dental caries. Quercetin, berberine, flavodoxin, berberine infusion, and tetrahydroberberine were the core components, and AKT1, JUN, IL-6, TNF, and Bcl-2 were the core targets. GO analysis showed that BP mainly included cytokine activity, signaling receptor activator activity, signaling receptor modulator activity, cytokine receptor binding, and receptor ligand activity, etc.; and CC mainly included the response to lipopolysaccharides, the response to bacterial molecules, cellular responses to lipids, inflammatory responses, and negative regulation of cell population proliferation; MF mainly includes membrane rafts, membrane microregions, extracellular matrix, external encapsulated structures, and plasma membrane protein complexes, etc. KEGG analysis showed that advanced glycosylation end product-receptor for advanced glycosylation end products (AGE-RAGE), TNF, IL-17, Toll-like receptor, hypoxia-inducible factor-1 (HIF-1), mitogen-activated protein kinase (MAPK), nuclear factor-κB (NF-κB), epidermal growth factor receptor (EGFR), Janus kinase-signal transducer and activator of transcription (JAK-STAT), and phosphatidylinositol 3-kinase-protein kinase B (PI3K-Akt) signaling pathways have been associated with C. chinensis treatment. The results of animal experiments showed that serum Bcl-2 protein expression increased and serum AKT1, JUN, IL-6, TNF, and other proteins decreased after the C. chinensis treatment. Conclusions:C. chinensis can be involved in regulating the targets of dental caries through multiple pathways, with good therapeutic effects and a wide range of mechanisms of action, and is expected to be an important component in the development of proprietary Chinese medicines for the treatment of dental caries.

Objective:To explore the mediating role of interdisciplinary cooperation ability between the level of hospice care practice and difficulty degree of hospice care for medical staff, in order to improve the quality of hospice care services for medical staff, and to provide evidence for relevant managers to formulate effective measures to reduce the implementation of hospice care difficulties.Methods:This study was a cross-sectional survey. Using convenience sampling method, the general data questionnaire, Palliative Care Difficulties Scale (PCDS), Palliative Care Self-Report Practice Scale (PCPS) and Modified Index of Interdisciplinary Collaboration (MIIC) were used to investigate 362 medical staff in all hospice care institutions of Shiyan City from July to August 2022.Results:The total score of PCDS in 362 medical staff was (40.58±13.44) points, (67.47 ± 12.50) points for PCPS and (108.36 ± 21.46) points for MIIC. There was a positive correlation between the total score of MIIC and PCDS ( r=0.500, P<0.01). The total score of PCPS was negatively correlated with the total score of MIIC ( r=-0.337, P<0.01) and the total score of PCDS ( r=-0.189, P<0.01). The interdisciplinary cooperation ability of medical staff in hospice care had a complete mediating effect between the level of practice and the degree of difficulty (Effect value=-0.190, 95% CI-0.274 to -0.126), and the mediating effect accounted for 98.5% of the total effect value. Conclusions:The practice level of hospice care can not directly affect the implementation of the difficulty degree, but by taking active measures to improve the interdisciplinary cooperation ability, so as to enhance the practice level, and then reduce the implementation of hospice care difficulty degree.

Conclusion:Procyanidin can inhibit proliferation and promote apoptosis of gastric cancer SNU-1 cells in vitro, which may be achieved by increasing intracellular ROS levels and reducing Bcl-2 protein expression.

Objective:To explore the pathogenic genes, clinical characteristics and treatment follow-up of children with congenital long QT syndrome (LQTS).Methods:Clinical data of 20 cases diagnosed with congenital LQTS and underwent gene testing from April 15, 2011 to April 15, 2021 in Department of Pediatric Cardiology, Shandong Provincial Hospital Affiliated to Shandong University were retrospectively collected and analyzed using independent sample t-test and Fisher′ s exact probability method. Results:LQTS-related gene mutations were detected in all the 20 cases, and pathogenic or suspected pathogenic mutations were identified in 18 cases (90.0%). Five LQTS mutation genes were discovered, including KCNQ1, KCNH2, SCN5A, CACNA1C and AKAP9.Eighteen cases (90.0%) had positive symptoms, and 13 cases (65.0%) had definite inducements.The inducement of symptoms in children with LQTS type 1(LQT1) was related to exercise, the causes of syncope in LQT1 and Jervell-Lange-Nielsen syndrome type 1 (JLNS1) with complex heterozygous mutations were exercise or emotional agitation; the causes of syncope in LQTS type 2 (LQT2) were unrelated to exercise; severe exercise in LQTS type 3 (LQT3) resulted in symptoms; and seizure in LQTS type 8 (LQT8) was non-induced.The corrected QT(QTc) interval of 20 cases was (553.1±66.6) ms, with a range of 460-707 ms, among which 17 cases showed QTc≥480 ms.The electrocardiogram(ECG) manifestations of children with various types of LQTS were different.There was no significant difference in QTc between different genders, or between children with syncope and those without syncope (all P>0.05). The follow-up time was (3.4±2.3) years, ranging from 0 to 8.3 years.Seventeen children received treatment[beta blockers and implantable cardiovertor-defibrillator(ICD)] and 3 cases did not.By the end of the follow-up, 1 child died, 19 cases survived, and 2 cases of the surviving children lost consciousness. Conclusions:There is a high consistency between genetic diagnosis and clinical diagnosis of congenital LQTS.The positive rate of gene detection is 90.0%.The clinical manifestations and ECG characteristics vary with genotypes.Beta blockers are protective.ICD therapy can prevent sudden cardiac death when oral medication does not respond.

Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.

Background Current evidence on whether occupational sulfur dioxide (SO₂) exposure affects the risk of hypertension is still limited, and the research results of the effect of environmental SO₂ exposure on risk of hypertension remain inconsistent. Objective To analyze the association between self-reported occupational exposure to SO₂ and the risk of hypertension, and the potential dose-response relationship between the years of exposure to SO₂ and the risk of hypertension. Methods Based on the Jinchang cohort, a nested case-control study design was adopted. A total of 841 newly diagnosed hypertension patients were followed up as the case group, and the control group was selected with 1∶1 individual matching based on non-occupational factors and occupational factors, respectively. The former matching conditions included age ±2 years old, same gender, working age ±2 years, and home address in the same sub-district. The latter was limited to working in the same workshop on the basis of the former conditions. Finally, the former included 717 controls and the latter included 488 controls. A unified questionnaire was used to collect general demographic characteristics, lifestyle habits, history of diabetes, family history of hypertension, and information on occupational exposure to SO₂ (self-reported history of occupational exposure to SO₂ and years of exposure to SO₂). Conditional logistic regression model was used to analyze the association between occupational exposure to SO₂ and hypertension, and the dose-response relationship between the years of SO₂ exposure and the risk of hypertension. Results In the nested case-control study matching with the non-occupational factors, the OR of hypertension in workers with self-reported occupational exposure to SO₂ was 2.39 (95%CI: 1.68-3.39); while when matching with the occupational factors, the OR of hypertension in workers with self-reported occupational exposure to SO₂ was 1.48 (95%CI: 1.04-2.12). The results of the dose-response relationship showed that as the SO₂ exposure years increased from 1-9 years, 10-19 years, 20-29 years, and 30 years and above, in the nested case-control study matching with non-occupational factors, the ORs of hypertension were 1.85 (95%CI: 0.68-5.08), 1.46 (95%CI: 0.58-3.67), 1.64 (95%CI: 1.00-2.67), and 4.95 (95%CI: 2.63-9.31), respectively; in the nested case-control study matching with occupational factors, the ORs of hypertension were 0.98 (95%CI: 0.40-2.41), 1.84 (95%CI: 0.72-4.70), 1.37 (95%CI: 0.82-2.29), and 2.44 (95%CI: 1.37-4.35), respectively. The two dose-response relationships were positive by χ² trend test (P_trend<0.05). Conclusion Self-reported occupational exposure to SO₂ is associated with the risk of hypertension in the study population, and the hypertension risk increases with the increase of SO₂ exposure years.
