RESUMEN
Objective To prepare a nano drug(PFOB@Lip-MMC)with liposome as the carrier,liquid perfluorooc-tyl bromide(PFOB)as core and mitomycin C(MMC)loading on the liposome shell and study its inhibitory effect on the proliferation of human pterygium fibroblasts(HPFs).Methods The thin film dispersion-hydration ultrasonic method was used to prepare PFOB@Lip-MMC and detect its physical and chemical properties.Cell Counting Kit-8,Cam-PI cell viability staining and flow cytometry were employed to detect the impact of different concentrations of PFOB@Lip-MMC on the via-bility of HPFs.DiI fluorescence labeled PFOB@Lip-MMC was used to observe the permeability of the nano drug to HPFs under a laser confocal microscope.After establishing HPF inflammatory cell models,they were divided into the control group(with sterile phosphate-buffered saline solution added),PFOB@Lip group(with PFOB@Lip added),MMC group(with MMC added),PFOB@Lip-MMC group(with PFOB@Lip-MMC added)and normal group(with fresh culture medi-um added)according to the experimental requirements.After co-incubation for 24 h,flow cytometer was used to detect the apoptosis rate of inflammatory cells,and the gene expression levels of interleukin(IL)-1β,prostaglandin E2(PGE2),tumor necrosis factor(TNF)-α and vascular endothelial growth factor(VEGF)in cells were analyzed by PCR.Results The average particle size and Zeta potential of PFOB@Lip-MMC were(103.45±2.17)nm and(27.34±1.03)mV,respec-tively,and its entrapped efficiency and drug loading rate were(72.85±3.28)％and(34.27±2.04)％,respectively.The sustained-release MMC of drug-loaded nanospheres reached(78.34±2.92)％in vitro in a 24-hour ocular surface environ-ment.The biological safety of PFOB@Lip-MMC significantly improved compared to MMC.In terms of the DiI fluorescence labeled PFOB@Lip-MMC,after co-incubation with inflammatory HPFs for 2 h,DiI fluorescence labeling was diffusely dis-tributed in the cytoplasm of inflammatory HPFs.The apoptosis rate of inflammatory HPFs in the PFOB@Lip-MMC group[(77.23±4.93)％]was significantly higher than that in the MMC group[(51.62±3.28)％].The PCR examination results showed that the gene transcription levels of IL-1 β,PGE2,TNF-α and VEGF in other groups were significantly reduced com-pared to the control group and PFOB@Lip group,with the most significant decrease in the PFOB@Lip-MMC group(all P＜0.05).Conclusion In this study,a novel nano drug(PFOB@LIP-MMC)that inhibited the proliferation of HPFs was successfully synthesized,and its cytotoxicity was significantly reduced compared to the original drugs.It has good bio-compatibility and anti-inflammatory effects,providing a new treatment approach for reducing the recurrence rate after pte-rygium surgery.
RESUMEN
Objective To study the effect of acetylation modification regulated by histone deacetylase inhibitors(HDACi)and his-tone acetyltransferase(HAT)on β2-adrenergic receptor(ADRB2)gene.Methods ADRB2 promoter plasmid(pADRB2-1918)was transfected into BEAS-2B cells,and sodium butyrate(SoB)and trichostatin A(TSA)were added respectively.Adenovirus E1 A-relat-ed kDa protein(p300)plasmid and PADRB2-1918 plasmid were co-transfected into BEAS-2B cells to acetylate histone in BEAS-2B cells.The activity of ADRB2 promoter in BEAS-2B cells treated with SoB,TSA,and p300 was detected by dual-luciferase gene re-porter assay.SoB and TSA were added to BEAS-2B cells,or p300 plasmid was transfected into BEAS-2B cells to acetylate histone in BEAS-2B cells.The relative expression of ADRB2mRNA in BEAS-2B cells was detected by quantitative real-time PCR(qRT-PCR),and the expression of ADRB2 protein in BEAS-2B cells was detected by Western blot.Results SoB,TSA,and p300 plasmid were added into BEAS-2B cells,respectively,which participated in histone acetylation in BEAS-2B cells.We found that the activities of ADRB2 promoter,mRNA,and protein expressions in BEAS-2B cells were lower than those in the control group(P＜0.05),and the differences were statistically significant.Conclusion Histone acetylation can inhibit the expression of ADRB2 in asthma susceptible genes.
RESUMEN
Objectives:To explore the relationship between insomnia symptoms and neuroticism in patients with COVID-19,and to explore the role of anxiety and psychological capital in the relationship.Methods:Totally 687 patients with COVID-19 were recruited from Shanghai Fangcang Hospital.The Athens Insomnia Scale(AIS),Eysenck Personality Questionnaire-Revised Short Scale for Chinese Neuroticism Subscale(EPQ-RSC-N),Self-Rat-ing Anxiety Scale(SAS)and Psychological Capital Questionnaire(PCQ)were used to measure insomnia symp-toms,neuroticism personality trait,anxiety symptoms and psychological capital levels.The deviation-corrected per-centile Bootstrap method was used to test the mediating effect,and the PROCESS program was used to test the moderated effect.Results:The detection rate of insomnia symptoms was 49.93％.The AIS scores were lower in male patients than in female patients(P＜0.01).The SAS scores partly mediated the relationship between neuroti-cism scores and AIS scores,with an effect size of 0.03,accounting for 18.29％of the total effect.With the im-provement of PCQ scores,the predictive effect of SAS scores on AIS scores gradually decreased(β=-0.01,t=-4.41,P＜0.001).Conclusions:Anxiety symptoms in patients with COVID-19 play a partial mediating role in the positive relationship between insomnia symptoms and neuroticism.The psychological capital moderates the relation-ship between insomnia and anxiety symptoms.
RESUMEN
Objective:To explore the effects of activating α7 nicotinic acetylcholine receptor(α7nAChR)on cognitive function and polarization of hippocampal microglia in traumatic brain injury (TBI) rats.Methods:Totally 36 male SD rats with 6-8 weeks old were randomly divided into Sham group ( n=12), TBI group ( n=12), TBI+ α7nAChR agonist group ( n=6) and TBI+ α7nAChR antagonist group( n=6). The TBI model was established by the " free fall impact" method. From the 4th to 6th day after modeling, mice in the TBI+ α7nAChR agonist group were intraperitoneally injected with α7nAChR agonist PNU-282987 (3 mg/kg). Rats in TBI+ α7nAChR antagonist group were intraperitoneally injected with α7nAChR antagonist methyllycaconitine citrate (5 mg/kg) first, then 45 minutes later they were injected with α7nAChR agonist PNU-282987 (3 mg/kg). Rats in the TBI group and Sham group were intraperitoneally injected with an equal volume of 0.9% sodium chloride solution. Morris water maze test was used to evaluate the learning and memory function of rats. Immunofluorescence staining was used to observe the ionized calcium binding adapter molecule 1 (Iba-1)(a marker for microglia) and arginase 1 (Arg-1)(a marker for M2 microglia). Western blot was used to detect the protein level of Arg-1 in hippocampal tissue. Statistical analysis was performed using GraphPad Prism 9 software. Independent sample t test was used for comparison between two groups, one-way ANOVA was used for comparison among multiple groups, and Tukey test was used for multiple comparison. Results:The results of the water maze test showed that after 7 days of modeling, there was a statistical difference in the escape latency among the 4 groups of rats ( F=6.134, P<0.05). There was no statistical difference in the escape latency between the TBI group and the TBI+ α7nAChR antagonist group( P>0.05), but the both were higher than that of the Sham group (both P<0.05). The escape latency of the TBI+ α7nAChR agonist group((31.87±9.01)s) was shorter than that of the TBI group((56.75±2.62)s) and the TBI+ α7nAChR antagonist group((60.00±0.00)s) (both P<0.05). The results of immunofluorescence staining showed that there were statistical differences in the fluorescence intensity and cell numbers of Arg-1 + /Iba-1 + among the four groups ( F=17.37, 9.33, both P<0.05). The immune fluorescence intensity (0.27±0.03) and cell numbers (21.67±4.41) of Arg-1 + /Iba-1 + in the TBI+ α7nAChR agonist group were higher than those in the TBI group((0.14±0.03), (11.33±2.60)) and TBI+ α7nAChR antagonist group((0.10±0.03), (7.67±1.20)) (all P<0.05). The results of Western blot showed that there was a statistical difference in the level of Arg-1 protein in hippocampus among the 4 groups ( F=8.323, P=0.001). There was no significant difference in the level of Arg-1 protein between the TBI group and the TBI+ α7nAChR antagonist group( P>0.05), and the level of Arg-1 protein in the TBI+ α7nAChR agonist group(1.06±0.22) was higher than that in the TBI group(0.60±0.13) and TBI+ α7nAChR antagonist group(0.35±0.10) (both P<0.05). Conclusion:Activating α7nAChR can promote the polarization of M2 type microglia in rat hippocampal tissue and improve the learning and memory function of TBI rats.
RESUMEN
AIM: To assess the efficacy of Quyin Koufuye in different types of psoriasis vulgaris and analyzes the relationship between efficacy and various disease-related factors, as well as its complementary role in biologic therapy. METHODS: This study included a total of 396 patients with psoriasis. Based on the patient history, participants were categorized into the biologics group (n=98), Quyin Koufuye-assisted biologics group (n=62), and Quyin Koufuye monotherapy group (n=236). Patient history data were collected, including gender, duration of illness, disease type, initial site of onset, degree of itching, recurrence status and time, smoking habits, joint pain, family history of psoriasis, nail damage, treatment plan, and PASI/BSA scores. A retrospective analysis was conducted to identify factors influencing the efficacy of Quyin Koufuye and to analyze its combined effects with biologics. RESULTS: Combining Quyin Koufuye with biologics significantly boosted the PASI90 response rate to 72.6% (P=0.014). Responders to PASI50 with Quyin Koufuye experienced longer recurrence intervals (> 6 months) than non-responders (50% vs. 33.6%, P= 0.045). Influencing factors included psoriasis-affected body surface area (OR=0.960, P=0.000), prolonged smoking history (OR=2.10, P=0.046), and psoriasis type (OR=2.47, P=0.015). CONCLUSION: This study underscores the synergy of Quyin Koufuye and biologics in treating psoriasis, particularly for longer recurrence intervals-factors like smoking history, psoriasis type, and affected body surface area impact Quyin Koufuye's efficacy.
RESUMEN
Objective:To verify the predictive value of the Second Revision of the International Staging System (R2-ISS) in newly diagnosed patients with multiple myeloma (MM) who underwent first-line autologous hematopoietic stem cell transplantation (ASCT) in a new drug era in China.Methods:This multicenter retrospective cohort study enrolled patients with newly diagnosed MM from three centers in China (Beijing Chao-Yang Hospital, Capital Medical University; the First Affiliated Hospital, Sun Yat-Sen University, and the Second Affiliated Hospital of Naval Medical University) from June 2008 to June 2018. A total of 401 newly diagnosed patients with MM who were candidates for ASCT were enrolled in this cohort, all received proteasome inhibitor and/or immunomodulator-based induction chemotherapy followed by ASCT. Baseline and follow-up data were collected. The patients were regrouped using R2-ISS. Progression-free survival (PFS) and overall survival (OS) were analyzed. The Kaplan-Meier method was used to analyze the survival curve and two survival curves were compared using the log-rank test. Cox regression analysis were performed to analyze the relationship between risk factors and survival.Results:The median age of the patients was 53 years (range 25-69 years) and 59.5% (240 cases) were men. Newly diagnosed patients with renal impairment accounted for 11.5% (46 cases). According to Revised-International Staging System (R-ISS), 74 patients (18.5 %) were diagnosed with stage Ⅰ, 259 patients (64.6%) with stage Ⅱ, and 68 patients (17.0%) with stage Ⅲ. According to the R2-ISS, the distribution of patients in each group was as follows: 50 patients (12.5%) in stage Ⅰ, 95 patients (23.7%) in stage Ⅱ, 206 patients (51.4%) in stage Ⅲ, and 50 patients (12.5%) in stage Ⅳ. The median follow-up time was 35.9 months (range, 6-119 months). According to the R2-ISS stage, the median PFS in each group was: 75.3 months for stage Ⅰ; 62.0 months for stage Ⅱ, 39.2 months for stage Ⅲ, and 30.3 months for stage Ⅳ; and the median OS was not reached, 86.6 months, 71.6 months, and 38.5 months, respectively. There were statistically significant differences in PFS and OS between different groups (both P<0.001). Multivariate Cox regression analysis showed that stages Ⅲ and Ⅳ of the R2-ISS were independent prognostic factors for PFS ( HR=2.37, 95% CI 1.30-4.30; HR=4.50, 95% CI 2.35-9.01) and OS ( HR=4.20, 95% CI 1.50-11.80; HR=9.53, 95% CI 3.21-28.29). Conclusions:The R2-ISS has significant predictive value for PFS and OS for transplant-eligible patients with MM in the new drug era. However, the universality of the R2-ISS still needs to be further verified in different populations.
RESUMEN
Objective:To investigate the efficacy and safety of acute stent implantation during endovascular treatment for patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis.Methods:A retrospective analysis was carried out on 46 patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis who received endovascular treatment at the Strategic Support Force Medical Center from January 2015 to August 2022. Twenty-seven patients underwent balloon angioplasty alone and 19 patients underwent acute stent implantation. The baseline characteristics, modified thrombolysis in cerebral infarction (mTICI) score of the responsible vessels, modified Rankin scale (mRS) score 90 days after operation, incidence of symptomatic intracranial hemorrhage and mortality of the two groups were evaluated.Results:The proportion of effective recanalization of the offending vessels (mTICI≥2b) in the acute stenting group was slightly higher than that in the balloon angioplasty group (16/19 vs. 81.5%), but the difference was not statistically significant ( P>0.05). Besides, there was no significant difference in the median of mRS between the acute stenting group [3.0(0, 4.0)] and the balloon angioplasty group [4.0(1.0, 5.0)] 90 days after operation ( P>0.05). In terms of safety, the incidence of symptomatic intracranial hemorrhage and mortality were comparable between the two groups ( P>0.05). Conclusions:The effect of acute stent implantation during endovascular treatment for patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis is not inferior to that of balloon angioplasty, and it does not increase the risk of intracranial bleeding complications.
RESUMEN
Objective:To survey the continuing medical education training needs for village doctors in Beijing suburbs.Methods:A qualitative study on the continuing medical education training needs for village doctors was conducted in Beijing Huairou district from March to July 2021. Six township hospital managers, 19 village doctors, 15 village cadres and 30 villagers from 15 villages of 3 townships in the district selected by purposive sampling method attended the face-to-face, individual, in-depth interviews. A semi-structured interview outline was developed based on literature review and expert consultation. The content of the interviews was analyzed by the thematic framework method.Results:Among 19 rural doctors, 11 preferred the full-time training, while 8 were unable to participate in the full-time training. Most of township hospital managers and village doctors thought the ideal form of training was "classroom knowledge teaching teaching" (5/6, 16/19)and "outpatient clerkship"(6/6, 13/19). The training contents for village doctors were basic medical knowledge and skills, including diagnosis and treatment of common diseases, identification of common symptoms and management of chronic diseases; the appropriate techniques of traditional Chinese medicine including acupuncture, moxibustion, cupping and scraping; and public health including epidemic prevention and control, infectious disease detection and reporting.Conclusion:For improving the applicability and practicality of training for village doctors, it is necessary to apply rational training methods and forms, and develop targeted training program and contents based on training needs.
RESUMEN
Background Affected by concentration, composition, and population tolerance of air pollutants, the relationship between air pollutants and population health has regional differences. There is still a research gap in Guiyang. Objective To explore the short-term effects of air pollutant concentrations in low-pollution areas on the outpatient volume of respiratory diseases. Methods Spearman correlation analysis was used to evaluate the correlation between air pollutants, meteorological factors, and respiratory outpatient volume from January 1, 2013 to December 31, 2020 in Guiyang City. A single pollutant distribution lag nonlinear model and a multi-pollutant interaction model were established based on Poisson distribution. A three-dimensional diagram was drawn to display the relationship between air pollutants and respiratory outpatient volume. Quantitative analysis was conducted on the attribution risk and lag effect of air pollutant concentration on outpatient volume of respiratory diseases in Guiyang City. Results The results of the single pollutant model showed that fine particulate matter (PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), and sulfur dioxide (SO2) elevated the outpatient volume of respiratory diseases. The maximum relative risk (RR) and 95%CI values of PM2.5, NO2,CO, and SO2 appeared on Day 2, 0, 5, and 6, respectively, which were 1.019 (1.015, 1.023), 1.146 (1.122, 1.171), 1.129 (1.116, 1.143), and 1.046(1.040, 1.052), respectively. For every quartile concentration increment of PM2.5, NO2, CO, or SO2, the outpatient volume of respiratory diseases increased by 0.943% (0.111%, 1.782%), 4.050% (3.573%, 4.529%), 0.595% (0.317%, 0.874%), or 0.667% (0.235%, 1.100%), respectively. The maximum RR (95%CI) of O3 was 1.015 (1.007, 1.023) and appeared on Day 0. The results of multi-pollutant model showed that PM2.5, NO2, CO, SO2, and O3 all elevated the outpatient volume of respiratory diseases. The maximum RR values of PM2.5, NO2, CO, SO2 and O3 appeared on Day 14, 0, 5, 7 and 0, respectively, which were 1.027 (1.021, 1.034), 1.213 (1.179, 1.248), 1.059 (1.043, 1.074), 1.016 (1.005, 1.026), and 1.024 (1.015, 1.033), respectively. Compared with the single pollutant model, the RR values of PM2.5, NO2, and O3 on the outpatient volume of respiratory diseases in the multi-pollutant model showed an upward trend, while the RR values of CO and SO2 in the multi-pollutant model showed a downward trend. Conclusion The impact of low concentrations of PM2.5, NO2, CO, and SO2 on human health cannot be ignored.
RESUMEN
Objective:To explore the effect of patient engagement on medication safety for patients with chronic disease through a systematic review.Methods:Relevant randomized controlled trials of patient engagement on medication safety were searched from PubMed, EMBASE, The Cochrane Library, CNKI, Wanfang and VIP database. The literature was screened according to inclusion and exclusion criteria, and data extraction and literature quality evaluation was conducted on the selected literature.Results:A total of 15 eligible studies was included. Most of the studies occurred in outpatient and home settings, and the subjects were patients with chronic diseases. Patient engagement strategies can be divided into three categories: (1) patient engagement in medical decision-making; (2) patient engagement in medication adjustment; (3) patient engagement in medication management. The outcomes of medication safety included medication adherence, medication knowledge, medication beliefs, adverse events and medication errors. Intervention strategies for patients to actively engage in medication safety significantly improved patients′ medication knowledge and beliefs, but did not improve medication adherence of patients.Conclusion:Promoting patient active engagement is an effective intervention measure to improve patients ′ perception of medication safety. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.
RESUMEN
Objective:To explore the prognostic prediction value of quantitative digital subtraction angiography (DSA) parameters in patients with acute anterior circulation ischemic stroke undergoing mechanical thrombectomy, and whether the clinical values vary by stroke etiology.Methods:This study was a post hoc analysis of the Multicenter Prospective Captor Trial. Patients with acute anterior circulation large-vessel occlusion and successful recanalization from April 2018 to July 2019 were screened. Post-processing analysis was performed on the DSA imaging sequence after recanalization, and 4 regions of interest (ROI) were selected in the target vessel: ROI1 (the proximal of the internal carotid artery-C2 segment), ROI2 (the starting point of the internal carotid artery-C7 segment), ROI3 (the end of the middle cerebral artery-M1 segment), and ROI4 (the end of the middle cerebral artery-M2 segment). Time to peak (TTP) was defined as the time at contrast concentration of selected ROI reached its maximum. Relative TTP (rTTP) was calculated by subtracting the TTP of ROI1 from the TTP of distalis ROIs. Successful recanalization was defined as modified Thrombolysis In Cerebral Infarction (mTICI) grade≥2b. Favorable outcomes at 3 months were defined as the modified Rankin Scale score≤2. According to the modified Rankin Scale score, the patients were divided into good prognosis group and poor prognosis group. The differences in clinical characteristics, postoperative hemodynamic parameters, and other data were compared between patients with good and poor prognoses. Univariate and multivariate Logistic regression was used to analyze factors related to a good prognosis. Finally, the prognostic prediction value of hemodynamic parameters was analyzed in patients with different Trial of Org10172 in Acute Stroke Treatment etiological classifications.Results:A total of 245 patients were collected, of which 161 patients [age 69 (60, 76) years, 92 (57.1%) male] were finally included in the analysis, including 36 cases of large artery atherosclerosis (LAA) stroke, 76 cases of cardiogenic embolism (CE), and 49 cases of other causes of stroke. Seventy-one (44.1%) patients had favorable outcomes at 3 months. The post-operative hemodynamic analysis indicated that patients with favorable outcomes ( n=71) had a higher proportion of mTICI grade 3 [54/71 (76.1%) vs 41/90 (45.6%),χ 2=15.26, P<0.001] and lower rTTP 31 [means TTP ROI3-TTP ROI1;0.33 (0.23, 0.54) s vs 0.47 (0.31, 0.65) s, Z=-2.71, P=0.007] than patients with unfavorable outcomes ( n=90). The mTICI score and rTTP 31 were respectively included in multivariate Logistic regression models. It was shown that mTICI grade 3 (adjusted OR=5.97, 95% CI 2.49-14.27, P<0.001) and rTTP 31 (adjusted OR=0.24, 95% CI 0.06-0.99, P=0.048) were significantly associated with favorable outcomes, and the area under the receiver operating characteristic curve of the models had no statistically significant difference ( P=0.170). Subgroup analysis showed that rTTP 31 was significantly associated with the prognosis of patients with LAA stroke ( OR=0, 95% CI 0-0.25, P=0.014), while mTICI grade was associated with the prognosis of patients with CE ( OR=3.91, 95% CI 1.40-10.91, P=0.009) and other etiologies ( OR=7.35, 95% CI 1.92-28.14, P=0.004). Conclusions:In patients with acute anterior circulation ischemic stroke and successful recanalization, both mTICI score and rTTP 31 had significant predictive value for favorable outcomes at 3 months. Moreover, rTTP 31 was significantly associated with the prognosis of patients with LAA stroke, while mTICI score was significantly related to the prognosis of patients with CE and other causes of stroke.
RESUMEN
Objective:To explore the clinical characteristics, treatment regimens and prognostic influencing factors of patients with multiple myeloma (MM) involving central nervous system (CNS).Methods:The clinical data of 18 MM patients involving CNS in Second Affiliated Hospital of Naval Medical University from January 2014 to June 2020 were retrospectively analyzed. Their clinical characteristics, treatment and prognosis were also analyzed. Kaplan-Meier method was used to make survival analysis and log-rank was performed; Cox proportional risk model was used to make univariate and multivariate analysis.Results:The cohort of 18 patients included 12 males and 6 females; the median age of patients involving CNS was 54 years (38-71 years). The median time from diagnosis to the involvement of CNS was 22 months (0-126 months).Among 18 patients, 1 case was primary MM involving CNS, and 17 cases were secondary MM involving CNS. All patients had Durie-Salmon (DS) stage Ⅲ; 10 cases had international staging system (ISS) stage Ⅲ, 6 cases had ISS stage Ⅱ, and 2 cases had ISS stage Ⅰ. Involvement sites of CNS included 7 cases of involving the dura mater alone and 4 cases of involving the pia mater alone, 2 cases of involving brain parenchyma and 5 cases of involving both meninges and brain parenchyma. The most common neurological symptoms were headache and cranial nerve palsy, and 9 patients had multiple neurological symptoms. All patients received systemic therapy, 16 patients received an intrathecal injection and/or radiotherapy; and the overall effective rate was 66.7%, including 3 achieving strict complete remission (sCR), 1 achieving complete remission (CR), 3 achieving very good partial remission (VGPR), 5 achieving partial remission (PR). The median overall survival (OS) was 32.7 months. Counting from the point of CNS involvement, the median progression-free survival (PFS) and OS time was 7.5 months, 12.2 months, respectively. The median PFS of MM patients in the dura-involved alone group was longer than that in the non-dura-involved alone group (15.1 months vs. 5.9 months, P = 0.009); the median OS of MM patients in the dura-involved alone group was longer than that in the non-dura-involved alone group (16.9 months vs. 10.7 months, P = 0.175). Multivariate Cox analysis showed that dura mater involvement alone was an independent factor affecting PFS in MM patients with CNS involvement ( HR = 0.191,95% CI 0.038-0.952, P = 0.043). Conclusions:MM involving CNS is rarely found and has a very poor prognosis. Different sites of CNS involvement could affect the prognosis of patients. There is a lack of effective treatment regimens.

Objective:To evaluate the curative effect of self-made Xingqi Jiedu Decoction combined with goserelin for endometriosis (EMT).Methods:Randomized controlled trial. A total of 84 patients with EMT in the hospital were enrolled as observation objects between July 2019 and July 2021. According to random number table method, they were divided into the control group (subcutaneous injection of goserelin) and the observation group (self-made Xingqi Jiedu Decoction on basis of control group), 42 in each group. All were treated for 6 months. TCM syndromes were scored before and after treatment. The severity of pelvic pain was evaluated by VAS. The levels of FSH, LH and estradiol (E 2) were detected by full-automatic chemiluminescence immunoassay and corresponding reagents, and levels of serum IL-1β, IL-8 and TNF-α were detected by ELISA. The adverse events were recorded, and clinical curative effect was evaluated. Results:The differences in total response rate between observation group and control group was statistically significant [95.24% (40/42) vs. 80.95% (34/42); χ2=4.09, P=0.043]. After treatment, scores of TCM syndromes and VAS in observation group were significantly lower than those in the control group ( t=14.30, 7.32, P<0.01). After treatment, FSH [(5.36±1.03) U/L vs. (6.20±1.35) U/L, t=3.21], E 2[(230.57±36.84) pmol/L vs. (265.28±37.53) pmol/L, t=4.28] and LH [(8.15±1.18) U/L vs. (9.24±2.01) U/L, t=3.03] in the observation group were significantly lower than those in the control group ( P<0.01). The levels of IL-1β, IL-8 and TNF-α in the observation group were significantly lower than those in the control group ( t=5.05, 5.07, 3.82, P<0.01). During treatment, differences in incidence of adverse reactions between observation group and control group was statistically significant [19.05% (8/42) vs. 4.76% (2/42); χ2=4.09, P=0.043]. Conclusion:The self-made Xingqi Jiedu Decoction combined with goserelin can improve hormone level, inhibit inflammatory response and improve clinical curative effect in EMT patients.
RESUMEN
Objective:To analyze the status of the dyadic coping in spouses of young and middle-age cervical cancer patients undergoing synchronous radiotherapy and chemotherapy, and to explore the influencing factors in bi-directional of patients and their spouses.Methods:With the convenience sampling method, a total of 150 cervical cancer patients undergoing synchronous radiotherapy and chemotherapy who were hospitalized in the Radiotherapy Department of Tianjin Medical University Cancer Institute and Hospital from March 2021 to February 2022 and their spouses were selected. A cross-sectional study was conducted by the Dyadic Coping Inventory, the Lock-Wallace Marital Adjustment Test, the General Self-Efficacy Scale, the Hospital Anxiety and Depression Scale, etc. Besides, multiple linear regression was used to identify predictors of the dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy.Results:The total score of dyadic coping, marital quality, general self-efficacy, anxiety and depression in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy were (121.69 ± 19.67), (97.23 ± 25.05), (25.13 ± 5.19), (9.98 ± 3.46), (8.19 ± 4.06) points. The scores of anxiety and depression of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy were (10.57 ± 3.60), (9.10 ± 4.12) points. Multiple linear regression analysis showed that factors of the patients′ anxiety and depression, spouse′s perception of marital quality, spouse′s general self-efficacy, changes in family relationship, family income, and period of radiotherapy were the main influencing factors ( P<0.01), which accounted for 55.7% of total variation. Conclusions:The level of dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy was medium, the marriage quality remains to be further improved,and its influence factors involved in the bi-directional of patient and spouse, including patients′ anxiety and depression, the changes of the family relationship, period of radiotherapy, spouses perception of marital quality and self-efficacy and family income. Clinical medical staff can improve the level of dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy by improving their cognition of disease, reducing the incongruence of dyadic illness appraisals, and taking multiple measures to reduce the economic burden felt of the spouses.
RESUMEN
Objective:To investigate the clinical efficacy of radical resection of pancreatic cancer after neoadjuvant conversion therapy.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 23 patients who underwent radical resection of pancreatic cancer after neoadjuvant conversion therapy in Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School from January 2019 to May 2022 were collected. There were 17 males and 6 females, aged 58(range, 33-73)years. After neoadjuvant conversion therapy, the three-dimensional (3D) visualization was used to evaluate and classify tumor vascular invasion, and surgical plan was planned and implemented. Observation indicators: (1) situations of neoadjuvant conversion therapy; (2) surgical situations; (3) postoperative histopathological examination; (4) postoperative recovery; (5) follow-up. Measurement data with normal distribution were represen-ted as Mean± SD, and measurement data with skewed distribution were represented as M(range) or M( Q1, Q3). Count data were described as absolute numbers. Results:(1) Situations of neoadjuvant conversion therapy. All 23 patients received the AG combination chemotherapy (albumin-paclitaxel+gemcitabine), including 14 patients combined with stereotactic body radiation therapy. Of the 23 patients, 22 cases achieved partial response, and 1 case showed stable disease. The CA19-9 of the 23 patients was 85.06(29.74,634.5)U/mL and 13.96(9.74,25.02)U/mL before and after neoadjuvant conversion therapy, respectively. (2) Surgical situations. According to the results of preoperative 3D visualization of tumor vascular invasion, 7 of the 23 patients were evaluated as arterial invasion, 8 cases were evaluated as venous invasion, 5 cases were evaluated as arterial and venous invasion, and there were 3 cases showing negative of vascular invasion. Of the 23 patients, 12 cases underwent pancreaticoduodenectomy, 4 cases underwent radical antegrade modular pancreatosplenectomy, 7 cases underwent total pancreaticoduodenectomy. For vascular reconstruction, there were 10 patients without vascular reconstruction, and there were 13 patients undergoing artificial vascular vein reconstruction. The operation time and volume of intraoperative blood loss of the 23 patients was (524±171)minutes and 1 000(400,1 600)mL, respectively. (3) Postoperative histopathological exami-nation. Results of postoperative histopathological examination in 23 patients showed that there were 2 cases with moderate-well differentiated tumor, 10 cases with moderate differentiated tumor, 7 cases with moderate-poorly differentiated tumor, 2 cases with poorly differentiated tumor, and 2 cases negative of tumor. The number of lymph node dissected in 23 patients was 16±7. There were 5 cases with lymph node metastasis and 18 cases without lymph node metastasis. There were 17 cases with nerve invasion and 6 cases without nerve invasion. All 23 patients were negative of vascular invasion. Of the 23 patients, there were 21 cases with R 0 resection and 2 cases with R 1 resection. For pathological TNM staging, there were 2 cases with 0 stage, 13 cases with Ⅰ stage, 7 cases with Ⅱ stage, and 1 case with Ⅳ stage. For postoperative pathological scoring, there were 2 cases achieved 0 point (complete pathological remission), 16 cases achieved 2 points (partial remission), and 5 cases achieved 3 points (no significant effect). (4) Postoperative recovery. The postoperative duration of hospital stay of 23 patients was 19(14,31)days. There were 17 of 23 patients underwent postoperative complications, including 11 cases with Clavien-Dindo Ⅱ stage complications, 3 cases with Clavien-Dindo Ⅲa stage complications, 1 case with Clavien-Dindo Ⅲb stage complication, 1 case with Clavien-Dindo Ⅳ stage complication, and 1 case with Clavien-Dindo Ⅴ stage complica-tion. (5) Follow-up. There were 22 patients underwent follow-up, with follow-up time as 12(9,23)months. There were 9 patients underwent postoperative recurrence and metastasis, with recurrence and metastasis time as 7.8(range, 6.0-12.0)months. During the follow-up, 15 of the 22 patients survived. Conclusion:Radical resection of pancreatic cancer after neoadjuvant conversion therapy is feasible.
RESUMEN
Objective:To study the genetic profiles and clinical characteristics of neonatal-onset genetic epilepsy.Methods:From July 2016 to May 2021, patients with neonatal-onset genetic epilepsy admitted to our hospital and received second-generation genetic sequencing were enrolled in this study. According to the types of genetic variations, the patients were assigned into ion channel group and non-ion channel group. Clinical characteristics, treatments and prognosis of the two groups were compared.Results:A total of 36 patients with identified genetic variations were enrolled, involving 15 epilepsy-related genes. KCNQ2, SCN2A and STXBP1 were the most common pathogenic genes. 20 cases (55.6%) were in the ion channel group and 16 cases (44.4%) in the non-ion channel group. No significant differences existed in their general status, seizure types, EEG characteristics, treatments and outcomes between the two groups ( P>0.05). Among all 36 cases, the age of onset ranged from 10 min to 24 d after birth and 28 cases (78.8%) developed epilepsy within 1 week after birth. Developmental and epileptic encephalopathies were diagnosed in 20 patients. 7 patients were diagnosed with self-limited neonatal epilepsy, 2 were pyridoxine dependence, 2 were Zellweger syndrome and 1 case of self-limited familial neonatal-infantile epilepsy, Turner type mental retardation with epilepsy, PURA syndrome, Rett syndrome and 22q11.2 deletion syndrome, each. The patients received antiepileptic drugs including phenobarbital, levetiracetam, oxcarbazepine, topiramate, valproic acid, benzodiazepines (nizepam/clonazepam /clobazam/midazolam), lacosamide and lamotrigine. 5 patients died after giving up treatment. 31 patients were followed up for 6 to 50 months. 22 cases (71.0%) were controlled at 1- to 35-month-old including 21 cases (56.7%) with developmental delay. 6 cases (19.4%) had ineffective seizure control and 3 cases (9.7%) showed reduced seizures, all with varying degrees of developmental delay. Conclusions:Neonatal-onset epilepsy is correlated with multiple genes. KCNQ2, SCN2A, STXBP1 are the common pathogenic genes with multiple variants of KCNQ2 gene. Most patients have seizures within 1 week after birth. More than half of patients have ion channel related gene variations. Sodium channel blockers have certain effects as treatment.
RESUMEN
Objective:To systematically evaluate the safety of family integrated care (FICare) model in neonatal intensive care unit (NICU).Methods:Multiple medical databases were searched for clinical studies on FICare in NICU published from January 1, 2010 to May 28, 2022. The quality of the literature was evaluated using Risk?of?Bias?2 tool?and cohort evaluation criteria from the Cochrane Systematic Evaluation Manual depending on the types of studies included. Meta-analysis was performed using Review Manager 5.3 software.Results:Six randomized controlled trials and four cohort studies were included for meta-analysis. The results of meta-analysis showed that compared with the traditional care model, FICare model did not increase the risk of nosocomial infection ( RR=0.75, 95% CI 0.46-1.24, P=0.27) and unstable medical conditions ( RR=0.86, 95% CI 0.61-1.22, P=0.40). No significant difference existed in the all-cause mortality between FICare and traditional care ( RR=2.74, 95% CI 0.88-8.57, P=0.08). Conclusions:FICare does not increase the risk of nosocomial infection, unstable medical conditions and adverse events compared with traditional care. It is safe and feasible to implement FICare in NICU.

Objective:To investigate the effects of ceftriaxone(CTX) on nuclear factor erythroid 2-related factor 2(Nrf2)/glutathione peroxidase 4(GPX4) pathway and ferroptosis in early brain injury in rats with subarachnoid hemorrhage(SAH).Methods:Forty-eight clean grade male SD rats were randomly divided into sham operation group (Sham group), SAH group, SAH+ CTX group and SAH+ CTX+ Nrf2 inhibitor group (SAH+ CTX+ ML385 group) according to the random number table with 12 rats in each group.Seven days before modeling, rats in SAH+ CTX+ ML385 group were injected intraperitoneally with ML385 (30 mg · kg -1) once a day for consecutive 7 days.And 5 days before modeling, rats in SAH+ CTX group and SAH+ CTX+ ML385 group were treated with CTX(200 mg · kg -1) by intraperitoneal injection once a day for five consecutive days.Rats in Sham group and SAH group were intraperitoneally injected with the same amount of 0.9% sodium chloride solution.After 24 hours of modeling, the neurological function score and brain tissue water content of rats in each group were measured.HE staining was used to observe the morphology of neurons in CA1 and CA3 regions of hippocampus.Prussian blue staining was used to observe the iron deposition in cerebral cortex.Spectrophotometer was used to determine the iron content, malonic dialdehyde(MDA) content, glutathione(GSH) content and GPX4 activity in cerebral cortex.Western blot was used to detect the expression levels of Nrf2 and GPX4 proteins in cerebral cortex.SPSS 23.0 was used for statistical analysis.One-way ANOVA was used to compare the mean of multiple groups of samples, and Dunnett- t test was used for further pairwise comparison between groups. Results:There was a statistically significant difference in the neurological function scores of rats in the four groups 24 hours after SAH ( F=48.40, P<0.001). The neurological function score of rats in the SAH group 24 hours after SAH was significantly lower than those in Sham group and SAH+ CTX group (both P<0.05). The brain water content of rats in the four groups 24 h after SAH was statistically significant ( F=49.61, P<0.001). The brain water content of rats in the SAH group 24 h after SAH was significantly higher than that in Sham group and SAH+ CTX group(both P<0.05). There was statistically significant differences in the number of neuronal necrosis in CA1 and CA3 regions of hippocampus in the four groups 24 hours after SAH ( F=17.44, 246.50, both P<0.001). The numbers of neuronal necrosis in CA1 and CA3 regions of hippocampus in SAH group were significantly higher than those in Sham group and SAH+ CTX group, and the numbers of neuronal necrosis in CA1 and CA3 regions of hippocampus in SAH+ CTX+ ML385 group were significantly higher than those in SAH+ CTX group (all P<0.05). Twenty-four hours after SAH, the amount of iron deposited in the cerebral cortex of rats in the four groups was statistically significant ( F=2 363.0, P<0.001). The iron deposition in the cerebral cortex of rats in the SAH group was significantly higher than those in Sham group and SAH+ CTX group (both P<0.05). There were significant differences in iron content, MDA content, GSH content and GPX4 activity in the cerebral cortex of the four groups 24 h after SAH( F=2 380.0, 1 322.0, 789.1, 815.5, all P<0.001). The content of iron and MDA in the cerebral cortex of rats in SAH group were significantly higher than those in Sham group, while the content of GSH and the activity of GPX4 were significantly lower than those in Sham group (all P<0.05). The content of iron and MDA in the cerebral cortex of rats in SAH+ CTX group were lower than those in SAH group, and the content of GSH and the activity of GPX4 were higher than those in SAH group (all P<0.05). At 24 h after SAH, the expression levels of Nrf2 and GPX4 protein in the cerebral cortex of the four groups were statistically significant ( F=888.7, 1 556.0, both P<0.001). The protein expression levels of Nrf2 (0.382±0.014) and GPX4 (0.329±0.019) in the cerebral cortex in SAH group were lower than those in Sham group ((0.746±0.009), (0.953±0.009)) (both P<0.05). The expression levels of Nrf2 (0.631±0.006) and GPX4 (0.833±0.008) protein in the cerebral cortex in the SAH+ CTX group were significantly higher than those in the SAH group (both P<0.05). The expression levels of Nrf2 (0.427±0.009) and GPX4 (0.525±0.011) protein in the cerebral cortex in SAH+ CTX+ ML385 group were significantly lower than those in SAH+ CTX group (both P<0.05). Conclusion:Ceftriaxone may inhibit ferroptosis during EBI in SAH rats by regulating Nrf2/GPX4 signal axis.
RESUMEN
Objective: To evaluate the long-term efficacy and safety of the implantable ventricular assist system EVAHEART I in clinical use. Methods: Fifteen consecutive patients with end-stage heart failure who received left ventricular assist device therapy in Fuwai Hospital from January 2018 to December 2021 were enrolled in this study, their clinical data were retrospectively analyzed. Cardiac function, liver and kidney function, New York Heart Association (NYHA) classification, 6-minute walk distance and quality of life were evaluated before implantation and at 1, 6, 12, 24 and 36 months after device implantation. Drive cable infection, hemolysis, cerebrovascular events, mechanical failure, abnormally high-power consumption and abnormal pump flow were recorded during follow up. Results: All 15 patients were male, mean average age was (43.0±7.5) years, including 11 cases of dilated cardiomyopathy, 2 cases of ischemic cardiomyopathy, and 2 cases of valvular heart disease. All patients were hemodynamically stable on more than one intravenous vasoactive drugs, and 3 patients were supported by preoperative intra aortic balloon pump (IABP). Compared with before device implantation, left ventricular end-diastolic dimension (LVEDD) was significantly decreased ((80.93±6.69) mm vs. (63.73±6.31) mm, P<0.05), brain natriuretic peptide (BNP), total bilirubin and creatinine were also significantly decreased ((3 544.85±1 723.77) ng/L vs. (770.80±406.39) ng/L; (21.28±10.51) μmol/L vs. (17.39±7.68) μmol/L; (95.82±34.88) μmol/L vs. (77.32±43.81) μmol/L; P<0.05) at 1 week after device implantation. All patients in this group were in NYHA class Ⅳ before implantation, and 9 patients could recover to NYHA class Ⅲ, 3 to class Ⅱ, and 3 to class Ⅰ at 1 month after operation. All patients recovered to class Ⅰ-Ⅱ at 6 months after operation. The 6-minute walk distance, total quality of life and visual analogue scale were significantly increased and improved at 1 month after implantation compared with those before operation (P<0.05). All patients were implanted with EVAHEART I at speeds between 1 700-1 950 rpm, flow rates between 3.2-4.5 L/min, power consumption of 3-9 W. The 1-year, 2-year, and 3-year survival rates were 100%, 87%, and 80%, respectively. Three patients died of multiple organ failure at 412, 610, and 872 d after surgery, respectively. During long-term device carrying, 3 patients developed drive cable infection on 170, 220, and 475 d after surgery, respectively, and were cured by dressing change. One patient underwent heart transplantation at 155 d after surgery due to bacteremia. Three patients developed transient ischemic attack and 1 patient developed hemorrhagic stroke events, all cured without sequelae. Conclusion: EVAHEART I implantable left heart assist system can effectively treat critically ill patients with end-stage heart failure, can be carried for long-term life and significantly improve the survival rate, with clear clinical efficacy.
