Objective The aim of this study was to evaluate the efficacy and side effects of sacubitril/valsartan in the treatment of patients with chronic kidney disease(CKD)at stage 5 with resistant hypertension,and to explore the cardiovascular benefits and security of medical in the patients.Methods Patients with CKD5 resistant hypertension diagnosed and treated in the First Affiliated Hospital of Guangxi Medical University from September 2020 to March 2022 were selected and divided into the observation group(treated with routine treatment of kidney disease at end-stage and sacubitril/valsartan)and control group(include droutine treatment of renal disease at end-stage and ACEI or ARB drugs)according to treatment strategy.The patients in both two groups were treated with adequate dialysis treatment and conventional drug treatment of renal disease at end-stage.The patients were followed up for at least 3 months,the clinical efficacy of three months after treated with sacubitril/valsartan was observed,and the efficacy indicators and security indicators and adverse cardiovascular events were observed,the occurrence of adverse effects during the period of drug use were compared with the control group.Results A total of 110 patients were included in this study and there were 55 cases in each group.There were no significant differences in gender,age,age of dialysis,etiology,dialysis mode and blood pressure between the two groups(P>0.05).The Systolic blood pressure(SBP),diastolic blood pressure(DBP),b-type urinary natriuretic peptide precursor(Pro-BNP)and cardiac function grade in the observation group after treatment was significantly decreased compared with before treatment.The left ventricular ejection fraction(LVEF)and the ratio of LVEF<50%in the observation group was significantly reduced after treatment(P<0.05).SBP,DBP and Pro-BNP decreased 3 months after treatment compared with the baseline before treatment,and improved significantly in the first month after treatment(P<0.05).The decrease of DBP and BNP before and after treatment was significantly different between the two groups,and the decrease of DBP and BNP was more significant in the observation group(P<0.05).The difference of LVEF and left ventricular end diastolic diameter(LVEDD)between the two groups before and after treatment was statistically significant,and the improvement was more obvious in the observation group(P<0.05).There were no significant differences in the safety indicators of serum potassium,estimated glomerular filtration rate(eGFR)and liver function between two groups before and after treatment(P>0.05).In terms of adverse reactions,only 1 case in the control group developed hyperkalemia within 3 months of follow-up,and no hypotension or other adverse reactions occurred in the two groups.Conclusions The treatment of patients with CKD stage 5 hypertension with sacubitril/valsartan has obvious cardiovascular benefits.Sacubitril/Valsartan has efficacy in lowering blood pressure,improving cardiac function and reducing volume load,with less adverse events and higher safety than control group.

OBJECTIVE To analyze the compositional differences between Fructus Tritici Levis and Triticum aestivum， and to provide reference for identification and quality control of both. METHODS Twenty batches of Fructus Tritici Levis and three batches of T. aestivum were collected， and their fingerprints were acquired by high-performance liquid chromatography and the similarities were evaluated by the Evaluation System of Similarity of Chromatographic Fingerprints of Traditional Chinese Medicine （2012 version）. Cluster analysis （CA）， principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） were performed to analyze the difference of Fructus Tritici Levis and T. aestivum from different regions， and the differential components were screened. The contents of the six identified components in Fructus Tritici Levis and T. aestivum were determined. RESULTS The similarities of the fingerprints of Fructus Tritici Levis ranged from 0.928 to 0.996， and the relative similarities of T. aestivum with Fructus Tritici Levis ranged from 0.761 to 0.773. A total of 19 common peaks were calibrated， and six components including linolenic acid， linoleic acid， 5-heptadecylresorcinol， 5-nonadodecylresorcinol， 5- heneicosylresorcinol， and 5-tricosylresorcinol were identified. The results of CA and PCA showed that Fructus Tritici Levis and T. aestivum could be clearly distinguished； the distribution of Fructus Tritici Levis from Anhui province was relatively concentrated. The results of OPLS-DA showed that linolenic acid， linoleic acid， and other six unknown compounds were the differential components between Fructus Tritici Levis and T. aestivum. The average contents of the six identified components in Fructus Tritici Levis were 0.100 9， 1.094 0， 0.005 1， 0.030 9， 0.098 2，and 0.024 8 mg/g， respectively； the contents of linolenic acid and linoleic acid in Fructus Tritici Levis were significantly higher than those in T. aestivum （P＜0.05）.CONCLUSIONS The established qualitative and quantitative methods are simple and reliable， and can be used for the identification and quality evaluation of Fructus Tritici Levis and T. aestivum. The identified differential components， such as linolenic acid and linoleic acid， can also provide clues for the differentiation and pharmacological study of Fructus Tritici Levis and T. aestivum.

Objective:To investigate the incidence characteristics and influencing factors of non-alcoholic fatty liver disease (NAFLD) in rural Uyghur ethnic group residents in Xinjiang Production and Construction Corps and to provide scientific evidence for early identification and prevention of NAFLD for residents.Methods:A total of 10 158 participants were included from the Xinjiang Uygur ethnic group population cohort. A prospective cohort study and Cox proportional hazards regression model analysis were used to explore the influencing factors and clustering of NAFLD, and the dose-response relationship between related biochemical indicators and the risk of NAFLD was studied using a restricted cubic spline.Results:The cumulative incidence rate of NAFLD was 6.9%, and the incidence density of NAFLD was 12.06/1 000 person-years. The incidence density of NAFLD in females was higher than in males (14.72/1 000 person-years vs. 9.17/1 000 person-years, P<0.001). The incidence density of NAFLD gradually increased with age in the total population, both men and women (all P<0.001). In the general population, an education level of junior high school or above was a protective factor for NAFLD, while older age, divorce, widowhood, overweight, obesity, hypertension, increased glomerular filtration rate, decreased HDL-C, increased LDL-C, and increased ALT were risk factors for NAFLD. Estimated glomerular filtration rate (eGFR), HDL-C, LDL-C, and ALT were non-linearly correlated with the incidence of NAFLD, and there was a significant dose-response relationship between them. Only 19.1% of residents had no NAFLD risk factors; over 80.9% had ≥1 NAFLD risk factors. The risk of NAFLD increased with the number of risk factors. Conclusions:The incidence of NAFLD in rural Uygur ethnic group residents in Xinjiang Production and Construction Corps was relatively low, but most residents had one or more risk factors for NAFLD. Prevention and control of NAFLD in this population cannot be ignored. In addition, people of older age, divorced or widowed, low education level, overweight or obese, hypertension, and abnormal eGFR, HDL-C, LDL-C, and ALT were the high-risk groups of NAFLD that need to be paid attention to in this population.

Background::There is a need for effective and safe therapies for psoriasis that provide sustained benefits. The aim of this study was to assess the efficacy and safety of tildrakizumab, an anti-interleukin-23p19 monoclonal antibody, for treating moderate-to-severe plaque psoriasis in Chinese patients.Methods::In this multi-center, double-blind, phase III trial, patients with moderate-to-severe plaque psoriasis were enrolled and randomly assigned (1:1) to receive subcutaneous tildrakizumab 100 mg or placebo at weeks 0 and 4. Patients initially assigned to placebo were switched to receive tildrakizumab at weeks 12, 16, and every 12 weeks thereafter. Patients in the tildrakizumab group continued with tildrakizumab at week 16, and every 12 weeks until week 52. The primary endpoint was the Psoriasis Area and Severity Index (PASI 75) response rate at week 12.Results::At week 12, tildrakizumab demonstrated significantly higher PASI 75 response rates (66.4% [73/110] vs. 12.7% [14/110]; difference, 51.4% [95% confidence interval (CI), 40.72, 62.13]; P <0.001) and Physician’s Global Assessment (60.9% [67/110] vs. 10.0% [11/110]; difference, 49.1% [95% CI, 38.64, 59.62]; P <0.001) compared to placebo. PASI 75 response continued to improve over time in both tildrakizumab and placebo-switching to tildrakizumab groups, reaching maximal efficacy after 28 weeks (86.8% [92/106] vs. 82.4% [89/108]) and maintained up to 52 weeks (91.3% [95/104] vs. 87.4% [90/103]). Most treatment-emergent adverse events were mild and not related to tildrakizumab. Conclusion::Tildrakizumab demonstrated durable efficacy through week 52 and was well tolerated in Chinese patients with moderate-to-severe plaque psoriasis.Trial registration::ClinicalTrials.gov, NCT05108766.

OBJECTIVE To discuss the relationship between the main concentration of air-borne pollen and the number of visits for allergic diseases in Chengde City. METHODS The daily airborne pollen concentration and species in Chengde City,Hebei Province were monitored by gravity sedimentation method from March 1 to October 15,in 2020-2022. The number of visits of patients with allergic rhinitis,asthma and conjunctivitis in department of otorhinolaryngology,respiratory and ophthalmology were counted by HIS system in the hospital computer center,furthermore,the correlation between pollen concentration and the number of visits of the above diagnosed patients was analyzed. RESULTS The pollen concentration in Chengde showed two peaks each year,which were in May in spring and August in autumn. The main pollen sources in spring were Pinaceae,ash,birch,ulmaceae,Cupressaceae,Moraceae and Rosaceaceae,accounting for 82.6％ of the total annual pollen(78.2％,83.5％,and 86.1％ in 2020-2022,respectively). In autumn,artemisia and humulus were the main sources of pollen,accounting for 9.94％ of the total annual pollen(11.4％,6.3％,12.11％,in 2020-2022,respectively). The number of outpatient visits patients with allergic rhinitis,asthma and conjunctivitis were higher in May and August than in other months,and the number of patients with allergic rhinitis in August was significantly increased compared with other months(P<0.05). The total monthly visits of the three departments and the visits of the three allergic diseases were positively correlated with pollen concentration. CONCLUSION The pollen concentration in the spring and autumn seasons of Chengde City has a direct impact on allergic diseases. Monitoring and broadcasting pollen concentration can provide early warning for doctors and patients,and provide effective information for early intervention,protection,and reasonable treatment of diseases.

Objective To explore the MRI characteristics of neonatal subpial hemorrhage and its relationship with prognosis.Methods A total of 43 newborns with subpial hemorrhage were selected.The original images were observed and analyzed by two radiologists for their radiological characteristics.The prognosis was evaluated using standardized scales such as the Gesell Intelligence Scale,Wechsler Intelligence Scale,and Bayley Intelligence Scale according to age.Results Neonatal subpial hemorrhage could be divided into type Ⅰ,type Ⅱ,and type Ⅲ.Type Ⅰ and type Ⅱ subpial hemorrhage could be completely absorbed without any abnormalities in the brain parenchyma.Type Ⅲ subpial hemorrhage could be completely absorbed and accompanied by varying degrees of cerebral softening and gliosis changes,and some cases may form local subarachnoid cavities.The clinical prognosis of type Ⅰ and type Ⅱ was better than that of type Ⅲ,and the difference was statistically significant(P=0.013).Based on the different signal between subpial hemorrhage and adjacent cortex,subcortical white matter,and deep brain white matter,two MRI features,"yin-yang sign"and"sandwich sign",were proposed.Conclusion The"yin-yang sign"and"sandwich sign"can enhance the understanding and diagnosis of neonatal subpial hemorrhage by radiologists and clinicians.MRI classification can be used as an imaging indicator to predict the prognosis of such hemorrhage.

Objective:To analyze the relevant factors affecting postnatal glucose metabolism in pregnant women with gestational diabetes and construct a nomogram prediction model.Methods:Using a retrospective study method, 210 cases of gestational diabetes patients admitted to Danyang People′s Hospital from March 2019 to November 2021 were selected as the study subjects, and they were divided into 125 cases of normal group and 85 cases of abnormal group according to the postnatal glucose metabolism. The predictive value was analyzed using the subject work characteristics (ROC) curve experiment; the risk factors affecting abnormal postpartum glucose metabolism in pregnant women with gestational diabetes mellitus were analyzed using Logistic regression experiment; and the clinical efficacy of the column-line diagram model was verified using internal data.Results:There was no statistically significant difference between the two groups when comparing the general information such as age ( P>0.05); compared with the normal group, the abnormal group had higher values of total cholesterol (TG), postprandial 2 h blood glucose (OGTT 2 h), glycosylated hemoglobin, and pre-pregnancy body mass index (BMI): (4.23 ± 1.35) mmol/L vs. (3.65 ± 1.50) mmol/L, (9.36 ± 1.25) mmol/L vs. (8.20 ± 1.51) mmol/L, (8.31 ± 2.96)% vs. (6.73 ± 2.23)%, (24.96 ± 4.21) kg/m 2 vs. (23.20 ± 3.25) kg/m 2, and those with a family history of diabetes mellitus were higher: 47.06%(40/85) vs. 20.80%(26/125), there were statistical differences ( P<0.05); the area under the curve (AUC) of TG, OGTT 2 h, glycated hemoglobin, and pre-pregnancy BMI were 0.605, 0.720, 0.670, and 0.616, with optimal cut off values of 4.65 mmol/L, 8.33 mmol/L, 8.06%, and 25.27 kg/m 2; TG (>4.65 mmol/L), OGTT 2 h (>8.33 mmol/L), glycated hemoglobin (>8.06%), and preconception BMI (>25.27 kg/m 2), and family history of diabetes mellitus (yes) were risk factors for abnormal glucose metabolism in pregnant women ( P<0.05); the C-index of the risk of postpartum glucose metabolism in pregnant women with gestational diabetes mellitus predicted by the column chart model was 0.750 (95% CI 0.672 - 0.864). The model predicted that the threshold of the risk of postnatal glucose metabolism in pregnant women with gestational diabetes mellitus was >0.07. Conclusions:TG (>4.65 mmol/L ), OGTT 2 h (>8.33 mmol/L ), glycated haemoglobin (>8.06%), pre-pregnancy BMI (>25.27 kg/m 2), and family history of diabetes (yes) are risk factors for abnormal glucose metabolism in pregnant women, and the model constructed based on the variables have good predictive power.

Celastrol is extracted from the traditional Chinese medicine Tripterygium wilfordii Hook.f..It is a kind of traditional Chinese medicine monomer with extensive pharmacological activity and has anti-tumor,anti-inflammation,anti-oxidation and neuroprotective effects.Studies have found that celastrol is not only closely related to obesity,tumor and cardiovascular diseases,but also plays a neuroprotective role in the cerebrovascular system by regulating various signaling pathways.At present,effective drugs for stroke are still limited,but with the deepening of the research on celastrol,its therapeutic potential in stroke has received more and more attention,especially in ischemic and hemorrhagic stroke,which has shown good therapeutic effects.Therefore,this is the first time to systematically summarize the therapeutic effects of celastrol on stroke and the underlying mechanisms involved,in order to provide further directions and references for the neuroprotective effects of celastrol.

Objective:To monitor the changes in donor gene chimerism ratio after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with severe beta-thalassemia using third-generation sequencing, and to explore the value of this technology in monitoring the proportion of donor genes chimerism in the early stage of postoperative allo-HSCT.Methods:Case analysis. Three beta-thalassemia patients at the First Affiliated Hospital of Guangxi Medical University during June-July 2022 who had undergone allo-HSCT with genotypes IVS-Ⅱ-654/CD41-42, IVS-Ⅱ-654/IVS-Ⅱ-654 and CD41-42/CD41-42 were included in this study. "Visual" analysis of the readouts of recipient DNA using third generation sequencing was used to monitor the genetic chimerism of the donor DNA and to compare with Sanger sequencing results. Post-transplantation follow-up was performed in the three patients to monitor the blood statistics and assess their implantation status and hematopoietic reconstitution.Results:The results of donor DNA chimerism status after allo-HSCT in the three patients detected by third generation sequencing were consistent with the Sanger sequencing results. The chimeric state of donor DNA gradually shifted to complete donor gene chimerism as the number of days after transplantation increased. Recipient 1 had 95.5% and 100% donor DNA chimerism at 10 and 20 d post-transplantation, respectively; recipient 2 had 100% donor DNA chimerism at 30 and 40 d post-transplantation; recipient 3 had 69.5% donor DNA chimerism at 1 d post-transplantation, and 100% donor DNA chimerism at 10 and 20 d post-transplantation. All patients achieved full donor gene chimerism within 30 d post-transplantation. Stable implantation of granulopoiesis, platelets, and erythropoiesis with hematopoietic reconstitution were obtained in all 3 patients within 1 month after transplantation.Conclusions:In this study, we developed a new method to detect the chimerism ratio of donor DNA using third-generation sequencing technology, enabling us to monitor the gene chimerism status of donor DNA at an early stage.
