Objective:To observe any effect of family rehabilitation interventions based on digital health management on elderly type 2 diabetes mellitus (T2DM) patients with sarcopenia.Methods:One hundred elderly T2DM patients with sarcopenia who had been discharged from hospital after treatment were divided into an observation group and a control group, each of 50. Both groups continued the diet control and training begun during their hospitalization, but the observation group was additionally provided with family rehabilitation based on digital health management. Before and after 3 months, the glucose and lipid metabolism and sarcopenia of both groups were evaluated with related symptom indexes, and their levels of diabetes self-management were compared.Results:Significant improvement was observed in both groups, but the average glucose and lipid metabolism indexes and sarcopenia-related symptom indexes of the observation group were significantly better than the control group′s averages. Their diabetes self-management was also significantly superior.Conclusion:Family rehabilitation based on digital health management can significantly improve glucose and lipid metabolism and muscle mass in elderly T2DM patients with sarcopenia. Such intervention is worthy of promotion and application in clinical practice.

Objective To investigate the effect and mechanism of Zhike Pingchuan Formula on reducing airway inflammation in mice with bronchial asthma(BA).Methods A total of 84 BALB/c mice were randomly separated into the control group,the BA group,the low-dose Zhike Pingchuan Formula group,the high-dose Zhike Pingchuan Formula group,the dexamethasone group,the lipopolysaccharide(LPS)group and the high-dose Zhike Pingchuan Formula+LPS group,with 12 mice in each group.The BA model was constructed in all groups of mice except the control group.After successful modeling,mice were treated with drug administration once a day for 3 weeks.Serum immunoglobulin E(IgE)concentration and levels of interleukin-17(IL-17)and tumor necrosis factor-α(TNF-α)in alveolar lavage fluid were detected by enzyme linked immunosorbent assay(ELISA).Pathological changes in lung tissue was detected by HE staining.The bronchial epithelium goblet cell proliferation and mucus secretion were determined by PAS staining.Flow cytometry was used to detect levels of T helper cell 17(Th17)and regulatory T(Treg)cell in mouse spleen tissue.Western blot assay was used to detect toll-like receptor 4(TLR4)/tumor necrosis factor receptor-associated factor 6(TRAF6)/nuclear factor kappa-B(NF-κB)pathway-related protein expression in lung tissue.Results Compared with the control group,damage of lung tissue was serious,the proliferation of bronchial epithelial goblet cells and the secretion of mucus increased,IgE concentration,TNF-α,IL-17 levels,Th17 cell proportion,Th17/Treg ratio,and TLR4,TRAF6,p-NF-κB p65 protein expression increased,while Treg cell proportion decreased in the BA group(P＜0.05).Compared with the BA group,the bronchial epithelial cupular cell proliferation and mucus secretion were reduced in the low-dose Zhike Pingchuan Formula group,the high-dose Zhike Pingchuan Formula group and the dexamethasone group,the lung tissue damage was improved,the concentration of IgE,levels of TNF-α,IL-17,the proportion of Th17 cells,the ratio of Th17/Treg and expression of protein levels of TLR4,TRAF6 and p-NF-κB p65 were reduced,and the proportion of Treg cell was elevated(P＜0.05).The trend of corresponding indexes in the LPS group was opposite to the above(P＜0.05).Compared with the high-dose Zhike Pingchuan Formula group,the pathological damage of lung tissue increased in the high-dose Zhike Pingchuan Formula+LPS group.The proliferation of bronchial epithelial goblet cells and the secretion of mucus increased,the IgE concentration,TNF-α,IL-17 levels,Th17 cell proportion,Th17/Treg ratio and TLR4,TRAF6,p-NF-κB p65 protein expression increased,while the Treg cell proportion decreased(P＜0.05).Conclusion Zhike Pingchuan Formula may reduce airway inflammation in BA mice by inhibiting TLR4/TRAF6/NF-κB pathway.

Objective:To investigate the relationship between serum soluble CD155 (sCD155), soluble CD163 (sCD163) and chemotherapy efficacy and prognosis in patients with diffuse large B-cell lymphoma (DLBCL).Methods:A total of 126 patients with DLBCL admitted to Handan Central Hospital from May 2018 to May 2020 (DLBCL group) and 126 healthy subjects (control group) were prospectively selected to compare serum sCD155 and sCD163 levels. According to the chemotherapy effect of DLBCL patients, they were divided into effective group and ineffective group, and the serum sCD155 and sCD163 levels were compared before and after treatment. The effective rate of chemotherapy in patients with different serum sCD155 and sCD163 levels was compared. Kaplan-Meier method was used to analyze the relationship between serum sCD155 and sCD163 levels and 3-year overall survival (OS) and progression-free survival (PFS) of DLBCL patients. Cox proportional risk regression model was used to analyze the prognostic factors of DLBCL patients.Results:The serum levels of sCD155 and sCD163 in DLBCL group were higher than those in control group before treatment (all P<0.05). The effective rate of chemotherapy in 126 DLBCL patients in this group was 69.8%(88/126). Compared with the effective group, the serum levels of sCD155 and sCD163 were higher in the ineffective group before and after treatment (all P<0.05). Compared with before treatment, serum sCD155 and sCD163 levels in the effective group were decreased after treatment (all P<0.05). The effective rate of DLBCL patients in sCD155 and sCD163 high level groups was lower than that in sCD155 and sCD163 low level groups (all P<0.05). Kaplan-Meier analysis showed that the 3-year OS and PFS of DLBCL patients in the low level group of sCD155 and sCD163 were higher than those in the high level group (all P<0.05). The high level of sCD155 and sCD163 were independent risk factors for 3-year PFS and OS in DLBCL patients (all P<0.05). Conclusions:Abnormal levels of serum sCD155 and sCD163 in DLBCL patients may reduce the efficacy of chemotherapy and lead to poor prognosis.

Conclusions:The anticipatory grief intervention scheme for family caregivers of advanced cancer patients is scientific, practical and feasible, and can be used for psychological nursing of family caregivers.

Objective:To investigate the clinical efficacy of different administration methods for labor analgesia.Methods:This randomized controlled study was conducted on 152 parturient women who underwent vaginal delivery at the Xinxiang Central Hospital from February to June 2023. These women were divided into a control group and an observation group, with 76 women per group. Women in the control group received 3 mL of 0.1% ropivacaine hydrochloride after routine epidural catheterization, followed by 3 mL of analgesic drugs after 3 minutes. For those without any special reactions, an analgesic pump containing 9 mL of medication was used after 3 minutes until the end of labor. In the observation group, 3 mL of 0.1% ropivacaine hydrochloride was administered as a trial dose before the epidural catheter was inserted into the epidural space. After 3 minutes, the postpartum woman lay flat and was given another 3 mL of analgesic pump medication. After 3 additional minutes, an additional 9 mL of the medication was administered. The analgesic pump was connected and turned on until the catheter was removed after delivery. The epidural catheter failure rate was assessed in each group. Before epidural puncture (T 1), within 30 minutes after the onset of anesthesia (T 2), and at the time of full dilation of the cervix (T 3), Visual Analogue Scale scores, the number of patient attempts to additionally use an analgesia pump, maternal satisfaction, the number of cases requiring cesarean section conversion, the incidence of adverse reactions (such as nausea, vomiting, and fever), and Apgar scores for newborns were recorded in each group. Results:The epidural catheter failure rate in the observation group was 1.3% (1/76), which was significantly lower than 10.5% (8/76) in the control group ( χ2 = 5.79, P < 0.05). At T 2 and T 3, the Visual Analogue Scale score in the observation group was (0.89 ± 0.08) points and (2.1 ± 0.07) points, respectively, which were significantly lower than (2.55 ± 0.07) points and (3.35 ± 0.07) points in the control group ( t = 238.54, 133.17, both P < 0.001). The number of patient attempts to additionally use an analgesia pump in the observation group was (1.00 ± 0.84) counts, which was significantly less than (4.00 ± 0.65) counts in the control group ( t = 29.47, P < 0.001). Maternal satisfaction in the observation group was 100% (76/76), which was significantly higher than 92.1% (70/76) in the control group ( χ2 = 6.25, P < 0.05). The number of cases requiring cesarean section conversion in the observation group was 0 (0/76), which was significantly lower than 52.6% (4/76) in the control group ( χ2 = 4.10, P < 0.05). Conclusion:Administering a trial dose (3 mL) of 0.1% ropivacaine hydrochloride before placing the epidural catheter during labor analgesia can greatly increase the placement success rate of the catheter and enhance pain relief effectiveness. This has a certain clinical application value.

OBJECTIVE To systematically review the efficacy and safety of ticagrelor versus clopidogrel in CYP2C19 loss-of-function carriers with mild ischemic stroke or transient ischemic attack(TIA). METHODS Databases such as PubMed, Embase, the Cochrane Library, CNKI, and Wanfang were systematically searched, and the search period was from database establishment to June 2022. Two reviewers independently screened literature, extracted data, and evaluated the methodological quality of the included studies. Meta-analysis was performed using RevMan 5.3 software. RESULTS A total of 2 studies with 7 087 patients were included. Compared with clopidogrel, ticagrelor reduced the incidence of stroke[RR=0.78, 95%CI(0.66−0.93), I2=0%, P=0.007] and vascular event[RR=0.78, 95%CI(0.66−0.91), I2=0%, P=0.002] in patients with mild ischemic stroke or TIA carrying the CYP2C19 loss-of-function allele. The incidence of any bleeding[HR=2.18, 95%CI(1.66−2.85)] and minor bleeding[HR=2.41, 95%CI (1.81−3.20)] in the ticagrelor-aspirin group was higher than that in the clopidogrel-aspirin group, and dyspnea (1.2% vs 0.2%, P<0.001) and arrhythmias(1.7% vs 0.8%, P=0.001) were more common in the ticagrelor-aspirin group than in the clopidogrel-aspirin group. There was no significant difference in the incidence of severe bleeding between the two groups. CONCLUSION Compared with clopidogrel, ticagrelor reduces the incidence of stroke and vascular events in patients with mild ischemic stroke or TIA carrying the CYP2C19 loss-of-function allele, and did not increase the risk of severe bleeding. However, the ticagrelor group had a higher incidence of minor bleeding, dyspnea and arrhythmias.

OBJECTIVE To investigate the mechanisms by which Pinggan Yishen Decoction(PGYSD)contributes to alleviating target organ damage in spontaneously hypertensive rats.METHODS The chemical components of PGYSD were determined by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS)and were analyzed by target a-nalysis and functional enrichment combined with network pharmacology methods to predict the potential mechanism of PGYSD in trea-ting hypertension and its target organ damage.Spontaneously hypertensive rats were randomly divided into the model group,low-dose PGYSD group(2 g·kg-1),high-dose PGYSD group(5 g·kg-1),and valsartan group(7.2 mg·kg-1),with 6 rats in each group.Wistar-Kyoto rats were used as the control group,and the control group and the model group were gavaged with normal saline for 8 consecutive weeks.HE and Masson staining were used to observe the pathological damage and fibrosis degree of rat heart and tho-racic aorta.Immunohistochemical staining and Western blot were used to detect the expression level of EGFR in the heart,liver and kidney of rats.Immunofluorescence staining was used to detect the co-localization of EGFR and EEA1 in the heart,liver and kidney of rats.RESULTS Twenty-six components of PGYSD were detected by UPLC-Q-TOF/MS.Network pharmacology revealed that EG-FR,PIK3R1 and EP300 may be key therapeutic targets of action of PGYSD for the treatment of hypertension and its target organ dam-age,and that the treatment of hypertension and its target organ damage by PGYSD may be closely related to EGFR tyrosine kinase in-hibitor resistance,lipids and atherosclerosis and HIF-1 signaling pathway.The high-dose group of PGYSD significantly reduced sys-tolic blood pressure and mean blood pressure in rats(P<0.05,P<0.01),attenuated pathological damage and fibrosis in the heart and thoracic aorta(P<0.01,P<0.001),significantly reduced the expression level of EGFR in the liver and kidney of rats(P<0.01),and treated fibrosis in liver and kidney,reduced the co-localization of EGFR and EEA1 in the kidney of rats(P<0.001),attenuated fibro-sis in kidney.CONCLUSION The paper integrates UPLC-Q-TOF/MS,network pharmacology and spontaneously hypertensive rat model and preliminarily explores the effect mechanism of PGYSD in the treatment of hypertension and its target organ damage,provi-ding a scientific basis for further mechanism research and clinical application of PGYSD in the treatment of hypertension.

Objective:To investigate the effect of on-demand glucocorticoid strategy on the occurrence and outcome of porcine anti-lymphocyte globulin (p-ALG) -associated serum sickness in aplastic anemia (AA) .Methods:The data of AA patients who received in the Anemia Diagnosis and Treatment Center of Haematology Hospital, CAMS & PUMC from January 2019 to January 2022 were collected. Among them, 35 patients were enrolled in the on-demand group, with the glucocorticoid strategy adjusted based on the occurrence and severity of serum sickness; 105 patients were recruited in the usual group by matching the age and disease diagnosis according to 1∶3 ratio in patients who received a conventional glucocorticoid strategy in the same period. The incidences, clinical manifestations, treatment outcomes of serum sickness, and glucocorticoid dosage between the two groups were analyzed.Results:The incidences of serum sickness in the on-demand group and the usual group were 65.7% and 54.3% ( P=0.237) , respectively. The median onset of serum sickness was the same [12 (9, 13) d vs the 12 (10, 13) d, P=0.552], and clinical symptoms and signs, primarily joint, and/or muscle pain, fever, and rash were similar. Severity grades were both dominated by Grades 1-2 (62.8% vs 51.4%) , with only a few Grade 3 (2.9% vs 2.9%) , and no Grades 4-5. No significant difference in the serum sickness distribution ( P=0.530) . The median duration of serum sickness was the same [5 (3, 7) d vs 5 (3, 6) d, P=0.529], and all patients were completely cured after glucocorticoid therapy. In patients without serum sickness, the average dosage of prophylactic glucocorticoid per patient in the usual group was (469.48 ±193.57) mg (0 in the on-demand group) . When compared to the usual group, the average therapeutic glucocorticoid dosage per patient in the on-demand group was significantly lower [ (125.91±77.70) mg vs (653.90±285.56) mg, P<0.001]. Conclusions:In comparison to the usual glucocorticoid strategy, the on-demand treatment strategy could significantly reduce glucocorticoid dosage without increasing the incidence of serum sickness; in addition, the duration of serum sickness and the incidence of above Grade 2-serum sickness were similar.

Objective:To analyze the diagnostic value of cell-free plasma metagenomic next-generation sequencing (mNGS) pathogen identification for severe aplastic anemia (SAA) bloodstream infection.Methods:From February 2021 to February 2022, mNGS and conventional detection methods (blood culture, etc.) were used to detect 33 samples from 29 consecutive AA patients admitted to the Anemia Diagnosis and Treatment Center of the Hematology Hospital of the Chinese Academy of Medical Sciences to assess the diagnostic consistency of mNGS and conventional detection, as well as the impact on clinical treatment benefits and clinical accuracy.Results:①Among the 33 samples evaluated by mNGS and conventional detection methods, 25 cases (75.76%) carried potential pathogenic microorganisms. A total of 72 pathogenic microorganisms were identified from all cases, of which 65 (90.28%) were detected only by mNGS. ②All 33 cases were evaluated for diagnostic consistency, of which 2 cases (6.06%) were Composite, 18 cases (54.55%) were mNGS only, 2 cases (6.06%) were Conventional method only, 1 case (3.03%) was both common compliances (mNGS/Conventional testing) , and 10 cases (30.3%) were completely non-conforming (None) . ③All 33 cases were evaluated for clinical treatment benefit. Among them, 8 cases (24.24%) received Initiation of targeted treatment, 1 case (3.03%) received Treatment de-escalation, 13 cases (39.39%) received Confirmation, and the remaining 11 cases (33.33%) received No clinical benefit. ④ The sensitivity of 80.77%, specificity of 70.00%, positive predictive value of 63.64%, negative predictive value of 84.85%, positive likelihood ratio of 2.692, and negative likelihood ratio of 0.275 distinguished mNGS from conventional detection methods (21/12 vs 5/28, P<0.001) . Conclusion:mNGS can not only contribute to accurately diagnosing bloodstream infection in patients with aplastic anemia, but can also help to guide accurate anti-infection treatment, and the clinical accuracy is high.
