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 investigate the effects of Qiangxin decoction on myocardial mitochondrial and energy metabolism in rats with chronic heart failure （CHF） based on mitophagy. METHODS Male SD rats were collected to establish CHF model by ligating the left anterior descending branch of coronary artery. The successful modeling rats were divided into model group， Qiangxin decoction group [12.25 g/（kg·d）， calculated by crude drug]， captopril group [10.38 mg/（kg·d）]， and Qiangxin decoction+captopril group （the same usage and dosage as single drug group） according to a random number table method， with 8 rats in each group. Another 8 normal rats were selected and received threading in the left anterior descending branch of the coronary artery without ligation as the sham operation group. Starting from the second day after successful modeling， the rats in administration groups were given relevant drug intragastrically， twice a day， for consecutive 28 days. After the last medication， the levels of adenosine triphosphate （ATP）， adenosine monophosphate （AMP） and free fatty acid （FFA） in infarcted myocardial tissues were detected， the pathological changes and mitochondrial morphology of the infarcted myocardial tissue were observed， as well as the protein expressions of B cell lymphoma-2 （Bcl-2）， Bcl-2 related X protein （Bax）， TANK-binding kinase 1 （TBK1）， p62 were detected in each group. RESULTS Compared with the sham operation group， the infarcted myocardial tissue fibrosis was changed evidently， with a large number of mitochondrial swelling and fusion， and internal cristae rupture； the levels of AMP and FFA， the protein expressions of Bax and p62 were all increased or up-regulated significantly in infarcted myocardial tissue， while the level of ATP， and the protein expressions of Bcl-2 and TBK1 were all decreased or down-regulated significantly （P＜0.05）. Compared with the model group， the pathological changes of infarcted myocardial tissue and mitochondrial swelling had been improved； the levels of AMP and FFA， and the protein expressions of Bax and p62 in infarcted myocardial tissue were significantly decreased or down-regulated in administration groups， while the level of ATP， and the protein expressions of Bcl-2 and TBK1 were increased or up-regulated significantly （P＜0.05）. And the effect of Qiangxin decoction+captopril group was better than that of single drug group. CONCLUSIONS Qiangxin decoction can alleviate myocardial fibrosis and mitochondrial swelling in CHF rats， and improve their myocardial energy metabolism， which may be related to regulating the expression of Bcl-2， Bax， TBK1 and p62 proteins and promoting myocardial mitophagy.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To investigate the clinical characteristics of survival in patients with high-risk myelodysplastic syndromes(HR-MDS)and provide a reference for the clinical prognosis of patients with HR-MDS.Methods General data,blood routine test,bone marrow smear with histopathology,cytogenetics,and other clinical data of 200 patients diagnosed with HR-MDS at Xiyuan Hospital of China Academy of Chinese Medical Sciences,during the period of January 2016-September 2022,were retrospectively analyzed.The included patients were categorized into the arsenic-containing herbal combination combined with demethylating agents(HMAs)treatment group and the arsenic-containing Chinese medicine compound combined with androgen treatment group.The influence of clinical indices on the survival characteristics of each group was analyzed.Results Comparison of the impact of clinical indicators on survival in 200 patients with HR-MDS who were treated with arsenic-containing herbal compounds in combination with HMAs or androgens showed that high-risk vs.very high-risk(P=0.018),hemoglobin(Hb)<80 g/L vs.Hb≥80 g/L(P=0.035),platelet(PLT)counts<50×109 L-1 vs.PLT counts≥50×109 L-1(P<0.001),and the difference in median progression-free survival(PFS)time between myelodysplastic syndromes converted to leukemia(MDS-AML)and non-MDS-AML(P=0.003)were statistically significant.Comparison of survival effects of clinical indicators in 68 patients with HR-MDS who were treated with arsenic-containing Chinese medicine compound combined with HMAs showed that the difference in median PFS between PLT count<50×109 L-1 and PLT count≥50×109 L-1(P<0.001)and the difference in median PFS between<5 and≥5 courses of chemotherapy(P=0.018)were statistically significant.Comparison of survival effects of clinical indicators in 132 patients with HR-MDS who were treated with arsenic-containing Chinese medicine compound combined with androgens showed that Hb<80 g/L and Hg≥80 g/L(P=0.028),PLT count<50×109 L-1 and PLT count≥50×109 L-1(P=0.002),and the mean differences in PFS between MDS-AML and non-MDS-AML(P=0.024)were statistically significant.Conclusion The clinical characteristics of long-surviving patients treated with arsenic-containing herbal combination in combination with HMAs included PLT counts≥50×109 L-1 and≥5 courses of chemotherapy.The clinical characteristics of long-surviving patients treated with arsenic-containing herbal combination in combination with androgens included Hg≥80 g/L,PLT count≥50×109 L-1,and non-MDS-AML.

This study aims to investigate the effects of Japanese encephalitis virus(JEV)on TLRs signaling pathway and its regulation of the secretion of inflammatory factors during the infection of testicular interstitial cells,In this study,the mRNA levels of TLR3,TLR7,TLR8,TRIF and MyD88 genes were detected by qPCR after 1 MOI dose of JEV was inoculated into testicular stro-mal cells at different time periods.Western blot assay was used to detect the expression levels of TLR3,TLR7,TRIF and MyD88 protein at 6 h after JEV infection,and ELISA was used to detect the expression levels of IL-1β,IL-6 and TNF-α at different time periods(6,12 and 24 h).The re-sults showed as follows:After 6 h of JEV infection,the mRNA levels of TLR3,TLR7,TRIF and MyD88 genes were significantly up-regulated(P＜0.05),and the mRNA levels of TLR8 genes were down-regulated(P＜0.05).Western blot results showed that the protein expressions of TLR3,TLR7,TRIF and MyD88 were significantly up-regulated when JEV infected testicular stromal cells for 6 h(P＜0.05),which was consistent with the corresponding mRNA transcription levels.There was no significant change in TLR8 protein expression.ELISA results showed that 6 h after JEV infection of testicular stromal cells,IL-6 was significantly increased(P＜0.01),and the expressions of IL-1β and TNF-α were not changed.TLR3,TLR7,TLR8,TRIF and MyD88 were si-lenced by siRNA,and the silenced cells were inoculated with JEV for 6 h,and IL-6 expression lev-els were detected by ELISA.The results showed that silenced TLR3,TLR7,TLR8,TRIF and MyD88 could significantly reduce the increase of IL-6 secretion induced by JEV infection(P＜0.05).These results indicated that JEV could induce the expression of inflammatory factor IL-6 by activating TLR3,TLR7 and TLR8 signaling pathway after infection of testicular stromal cells.This study provides a reference for further elucidating the mechanism of reproductive disorders caused by JEV infection.

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.

This study systematically analyzed the current status of outcomes in randomized controlled trial(RCT) of traditional Chinese medicine(TCM) treatment of diabetic kidney disease(DKD), aiming to provide a reference for constructing the core outcome set(COS) of TCM treatment of DKD. The clinical RCTs of TCM treatment of DKD that were published from January 2019 to March 2024 were retrieved from seven databases: CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, and Web of Science. The risk of bias was assessed and outcome indicators were qualitatively analyzed. A total of 323 RCTs were included, reporting 199 outcome indicators with the frequency of 3 744 in seven indicator domains: TCM syndromes(196 times, 5.24%), symptoms and signs(275 times, 7.35%), physical and chemical examinations(2 820 times, 75.32%), safety events(422 times, 11.27%), long-term prognosis(21 times, 0.56%), quality of life(9 times, 0.24%), and economic evaluation(1 time, 0.02%). The three most frequently applied outcome indicators were total clinical response rate(268 times, 82.97%), serum creatinine(251 times, 77.71%), and urea nitrogen(206 times, 63.78%). The outcomes in the studies of TCM treatment of DKD had the limitations of high risk of bias, lack of standardization of TCM syndromes and efficacy evaluation, neglect of endpoint indicators, large differences in endpoint indicators and time points of measurement, unclear primary and secondary outcomes, few application of long-term prognosis, quality of life, and economic indicators, and insufficient reporting of safety events. In the future, efforts should be made to actively promote the construction of COS in the studies about the TCM treatment of DKD and enhance the quality of the clinical studies.

Objective To investigate the expression of inositol polyphosphate 4-phosphatase type Ⅱ B(INPP4B)in colorectal cancer(CRC)and the relevant clinical significance,to determine the relationship between INPP4B and matrix metallopeptidase 7(MMP7)in CRC cells,and to make preliminary exploration of the effects of INPP4B on the proliferation and migration of CRC cells and mechanisms involved.Methods The TIMER2.0 and GEPIA2 databases were used to analyze the differences in INPP4B expression between cancer and para-cancerous tissues and the effects of such differences on the prognosis of CRC.The expression of INPP4B in 102 surgically resected CRC tumors was determined by immunohistochemistry(IHC),and the correlation between INPP4B and clinical pathological indicators was analyzed.In CRC cells with overexpressed/knocked-down INPP4B,the expression of INPP4B and MMP7 were examined by real time fluorogenic quantitative PCR,the protein expression of INPP4B was assessed by Western blot,cell proliferation was determined using the CellTiter 96? AQueous One assay,and cell migration and invasion were assessed using wound healing assay and real-time label-free dynamic cell analysis(RTCA).The LinkedOmics database was used to analyze signaling pathways related to INPP4B function,and the role of potential key molecules was validated at the cellular level.Results Analysis with the TIMER2.0 database and GEPIA2 database showed elevated INPP4B expression(colon adenocarcinoma[COAD]:2.30,rectal adenocarcinoma[READ]:2.33)in CRC compared to normal tissue(COAD:1.91,READ:1.89).IHC testing confirmed that INPP4B was upregulated in clinical CRC tissues and paracancerous tissues(P＜0.001).Cox regression model analysis showed that INPP4B(hazards ratio[HR]=1.457,95％confidence interval[CI]:1.003-2.115)affected the prognosis of CRC,and the Kaplan-Meier curve showed that patients with high INPP4B expression had shorter overall survival(P＜0.05).x2 test was performed to analyze the relationship between INPP4B expression and clinicopathological indexes,and it was found that high expression of INPP4B was correlated with lymph node metastasis(x2=3.997,P=0.046)and neural invasion(x2=8.511,P=0.004).In in vitro experiments,CRC cells overexpressing INPP4B showed a significantly increased cell proliferation and migration compared to the cells in the control group(P＜0.05).Analysis using the LinkedOmics database showed that INPP4B was correlated with extracellular matrix remodeling and cell migration.Pearson's correlation analysis showed that MMP7 was positively correlated with INPP4B(r=0.3782,P＜0.001).INPP4B overexpression or knockdown in vitro also led to the upregulation or the downregulation of MMP7 expression in CRC cells.Conclusion INPP4B is highly expressed in CRC tissues and significantly correlated with lymph node metastasis,neural invasion,and patient prognosis.MMP7 may mediate the role of INPP4B in promoting CRC cell migration and invasion.

COVID-19 is caused by a novel coronavirus-severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), which has being spreading around the world, posing a serious threat to human health and lives. Neutralizing antibodies and small molecule inhibitors for virus replication cycle are the main antiviral treatment for novel coronavirus recommended in China. To further promote the rational use of antiviral therapy in clinical practice, the National Center for Infectious Diseases (Beijing Ditan Hospital Capital Medical University and the First Affiliated Hospital, Zhejiang University School of Medicine) invited experts in fields of infectious diseases, respiratory and intensive care to develop an Expert Consensus on Antiviral Therapy of COVID-19 based on the Diagnosis and Treatment Guideline for COVID-19 ( trial version 10) and experiences in the diagnosis and treatment of COVID-19 in China. The consensus is concise, practical and highly operable, hopefully it would improve the understanding of antiviral therapy for clinicians and provide suggestions for standardized medication in treatment of COVID-19.

BACKGROUND: Weather conditions are a possible contributing factor to age-related macular degeneration (AMD), a leading cause of irreversible loss of vision. The present study evaluated the joint effects of meteorological factors and fine particulate matter (PM_2.5) on AMD. METHODS: Data was extracted from a national cross-sectional survey conducted across 10 provinces in rural China. A total of 36,081 participants aged 40 and older were recruited. AMD was diagnosed clinically by slit-lamp ophthalmoscopy, fundus photography, and spectral domain optical coherence tomography (OCT). Meteorological data were calculated by European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis and were matched to participants' home addresses by latitude and longitude. Participants' individual PM_2.5 exposure concentrations were calculated by a satellite-based model at a 1-km resolution level. Multivariable-adjusted logistic regression models paired with interaction analysis were performed to investigate the joint effects of meteorological factors and PM_2.5 on AMD. RESULTS: The prevalence of AMD in the study population was 2.6% (95% CI 2.42-2.76%). The average annual PM_2.5 level during the study period was 63.1 ± 15.3 µg/m³. A significant positive association was detected between AMD and PM_2.5 level, temperature (T), and relative humidity (RH), in both the independent and the combined effect models. For PM_2.5, compared with the lowest quartile, the odds ratios (ORs) with 95% confidence intervals (CIs) across increasing quartiles were 0.828 (0.674,1.018), 1.105 (0.799,1.528), and 2.602 (1.516,4.468). Positive associations were observed between AMD and temperature, with ORs (95% CI) of 1.625 (1.059,2.494), 1.619 (1.026,2.553), and 3.276 (1.841,5.830), across increasing quartiles. In the interaction analysis, the estimated relative excess risk due to interaction (RERI) and the attributable proportion (AP) for combined atmospheric pressure and PM_2.5 was 0.864 (0.586,1.141) and 1.180 (0.768,1.592), respectively, indicating a synergistic effect between PM_2.5 and atmospheric pressure. CONCLUSIONS This study is among the first to characterize the coordinated effects of meteorological factors and PM_2.5 on AMD. The findings warrant further investigation to elucidate the relationship between ambient environment and AMD.
