OBJECTIVE: To evaluate the clinical efficacy and safety of Yangxue Qingnao Pills (YXQNP) combined with amlodipine in treating patients with grade 1 hypertension. METHODS: This is a multicenter, randomized, double-blind, and placebo-controlled study. Adult patients with grade 1 hypertension of blood deficiency and Gan (Liver)-yang hyperactivity syndrome were randomly divided into the treatment or the control groups at a 1:1 ratio. The treatment group received YXQNP and amlodipine besylate, while the control group received YXQNP's placebo and amlodipine besylate. The treatment duration lasted for 180 days. Outcomes assessed included changes in blood pressure, Chinese medicine (CM) syndrome scores, symptoms and target organ functions before and after treatment in both groups. Additionally, adverse events, such as nausea, vomiting, rash, itching, and diarrhea, were recorded in both groups. RESULTS: A total of 662 subjects were enrolled, of whom 608 (91.8%) completed the trial (306 in the treatment and 302 in the control groups). After 180 days of treatment, the standard deviations and coefficients of variation of systolic and diastolic blood pressure levels were lower in the treatment group compared with the control group. The improvement rates of dizziness, headache, insomnia, and waist soreness were significantly higher in the treatment group compared with the control group (P<0.05). After 30 days of treatment, the overall therapeutic effects on CM clinical syndromes were significantly increased in the treatment group as compared with the control group (P<0.05). After 180 days of treatment, brachial-ankle pulse wave velocity, ankle brachial index and albumin-to-creatinine ratio were improved in both groups, with no statistically significant differences (P>0.05). No serious treatment-related adverse events occurred during the study period. CONCLUSIONS Combination therapy of YXQNP with amlodipine significantly improved symptoms such as dizziness and headache, reduced blood pressure variability, and showed a trend toward lowering urinary microalbumin in hypertensive patients. These findings suggest that this regimen has good clinical efficacy and safety. (Registration No. ChiCTR1900022470).

Aim To investigate the mechanism by which formononetin (FN) inhibits mitochondrial dynamic-related protein 1 (DRP1) -NLRP3 axis via intervening the generation of ROS to reduce allergic airway inflammation. Methods In order to establish allergic asthma mouse model, 50 BALB/c mice aged 8 weeks were divided into the control group, model group, FN treatment group and dexamethasone group after ovalbumin (OVA) induction. Airway inflammation and collagen deposition were detected by HampE and Masson staining. Th2 cytokines and superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and IgE levels in bronchoalveolar lavage fluid (BALF) were measured by ELISA, ROS in BEAS-2B cells was assessed by DCFH-DA staining, DRP1 expression in lung tissue and BEAS-2B cells was detected by immunohistochemistry and immunofluorescence, and the DRP1-NLRP3 pathway was analyzed by immunoblotting. Results FN treatment could effectively ameliorate the symptoms of asthmatic mouse model, including reducing eosinophil accumulation, airway collagen deposition, decreasing Th2 cytokine and IgE levels, reducing ROS and MDA production, increasing SOD and CAT activities, and regulating DRP1-NLRP3 pathway-related protein expression, thereby relieving inflammation. Conclusion FN ameliorates airway inflammation in asthma by regulating DRP1-NLRP3 pathway.

Objective:To explore the clinical characteristics,molecular characteristics,treatment and prognosis of pediatric Philadelphia chromosome-like acute lymphoblastic leukemia(Ph-like ALL)with a therapeutic target.Methods:A total of 27 patients of Ph-like ALL with targeted drug target were initially diagnosed in Children's Hospital of Soochow University from December 2017 to June 2021.The data of age,gender,white blood cell(WBC)count at initial diagnosis,genetic characteristics,molecular biological changes,chemotherapy regimen,different targeted drugs were given,and minimal residual disease(MRD)on day 19,MRD on day 46,whether hematopoietic stem cell transplantation(HSCT)were retrospective analyed,and the clinical characteristics and treatment effect were summarized.Survival analysis was performed by Kaplan-Meier method.Results:The intensity of chemotherapy was adjusted according to the MRD level during induced remission therapy in 27 patients,10 patients were treated with targeted drugs during treatment,and 3 patients were bridged with HSCT,1 patient died and 2 patients survived.Among the 24 patients who did not receive HSCT,1 patient developed relapse,and achieved complete remission(CR)after treatment with chimeric antigen receptors T cells(CAR-T).The 3-year overall survival,3-year relapse-free survival and 3-year event-free survival rate of 27 patients were(95.5±4.4)％,(95.0±4.9)％and(90.7±6.3)％respectively.Conclusion:Risk stratification chemotherapy based on MRD monitoring can improve the prognosis of Ph-like ALL in children,combined with targeted drugs can achieve complete remission as soon as possible in children whose chemotherapy response is poor,and sequential CAR-T and HSCT can significantly improve the therapeutic effect of Ph-like ALL in children whose MRD is continuously positive during induced remission therapy.

Aim To investigate the effect of Celastrol on the expression of Ezrin in tissues and HaCaT cells of DNCB sensitisation-induced atopic dermatitis(AD)mice.Methods BALB/c mice were taken and ran-domly divided into the control,DNCB group,Celastrol 25 μg,50 μg,75 μg treatment group,and Dex group,with 8 mice in each group;HaCaT cells were induced with TNF-α and treated with 1 μmol·L-1 Celastrol and Ezrin siRNA.The thickness of the skin on the ear and back of mice was measured by a thickness gauge,and the spleen and lymph nodes of mice were taken to observe the changes.HE and toluidine blue staining were used to observe the inflammatory cells and mast cell infiltration in mice.Flow cytometry was used to detect the levels of IL-4 and TNF-α in the lymph nodes of mice,and enzyme-linked immunosorbent was used to determine the levels of IL-4,TNF-α and IgE in serum of mice,and the expression of IL-4,IL-5 and IL-13 in the supernatant of HaCaT cells.Western blot was used to detect the expression of P-Ezrin and Ezrin in skin tissues.Results Celastrol significantly inhibited the swelling of ear and back skin tissues,reduced the de-granulation of inflammatory cells and mast cells,low-ered serum IgE and serum and lymph node levels of IL-4 and TNF-α,and reduced the activation of Ezrin in mice,and the expression of IL-4,IL-5 and IL-13 in the supernatant of HaCaT cells was restored by the treat-ment with Ezrin siRNA.Conclusion Celastrol amel-iorates AD,which may be achieved by modulating Ezrin activation.

Objective To explore the regulatory mechanism of Macelignan on oxidative stress-mediated neuronal injury in autophagy and apoptosis.Methods Murine hippocampal neuronal HT22 cells were treated with 2.5 mmol·L-1 glutamic acid(Glu)to establish an oxidative stress cell model.The cells were divided into normal group(normal cultured cells),model group(2.5 mmol·L-1 Glu)and experimental-L,-M,-H groups(2.5,5,10 μmol·L-1Macelignan treatment),inhibitor group(2.5 mmol·L-1 Glu+10 μmol·L-1 Macelignan+10 μmol·L-1 LY294002).Aoptosis rate was detected by flow cytometry;the protein expression level of autophagy-related protein LC3B(LC3B),anti-SQSTM1/p62(p62),p21,B-cell lymphoma-2(Bcl-2)and Bcl-2 associated X protein(Bax)was detected by Western blot.Results The apoptosis rates in the normal group,model group and experimental-L,-M,-H groups were(4.58±1.25)％,(8.75±0.55)％,(6.30±1.71)％,(5.97±2.27)％and(5.49±1.71)％.The difference between model group and normal group was statistically significant(P＜0.01).The difference between experimental-L,-M,-H groups and model group was statistically significant(all P＜0.01).The levels of LC3B in normal group,model group,experimental-L,experimental-M,experimental-H groups and inhibitor group were 0.28±0.02,0.74±0.02,1.02±0.04,0.70±0.03,0.26±0.02 and 0.21±0.01;p62 levels were 0.49±0.08,0.33±0.03,0.50±0.07,0.59±0.01,0.64±0.13 and 0.65±0.06;p21 levels were 0.87±0.02,1.18±0.03,0.98±0.03,0.88±0.03,0.72±0.06 and 0.81±0.02;Bcl-2/Bax levels were 1.74±0.23,1.11±0.10,1.38±0.05,1.66±0.26,1.58±0.29 and 1.53±0.09,respectively.The differences between model group and normal group,between model group and experimental-H group,between model group and inhibitor group,were also statistically significant(all P＜0.01).Conclusion Macelignan can reduce the damage of hippocampal neurons induced by glutamate acid by regulating the process of autophagy and apoptosis,and has obvious neuroprotective effect.

Objective To investigate the efficacy and safety of stereotactic body radiotherapy(SBRT)combined with camrelizumab and apatinib in treatment of advanced hepatocellular carcinoma(HCC).Methods The clinical data were retrospectively analyzed of 85 patients with advanced HCC treated in the Fifth Affiliated Hospital of Zhengzhou University and People's Hospital of Zhengzhou from January 2019 to September 2021.They were divided into observation group(n=31,SBRT combined with camrelizumab and apatinib)and control group(n=54,treated with camrelizumab and apatinib)according to whether they received SBRT.The propensity score matching(PSM)was used to balance the influence of confounding factors.The objective remission rate(ORR)and disease control rate(DCR)were compared between the two groups.The 6-month overall survival rate,1-year overall survival rate and progression-free survival(PFS)were compared between the two groups by Kaplan-Meier method.The safety of the two groups was evaluated by Common Terminology Criteria for Adverse Events(CTCAE)version 5.0.Results Before PSM,there were significant differences in age(P=0.043),number of extrahepatic metastasis(P=0.028),and previous surgical treatment(P=0.038)between the two groups.After PSM,there was no significant difference in baseline characteristics between the two groups(P>0.05).After PSM,27 cases were included in each groups,and three months after treatment,the ORR in observation group and control group were 66.7%and 29.6%,respectively,showed difference with statistically significant(P=0.006);and the DCR in the both groups were 96.3%and 85.2%respectively,showed no statistically significant difference(P=0.175).There were statistical differences in 6-month overall survival rate(96.3%vs.80.9%,P=0.001),1-year overall survival rate(75.0%vs.61.4%,P=0.034)and median PFS(8 months vs.5 months,P=0.003)between the observation group and control group.Multi-factor Cox regression analysis showed that baseline alpha-fetoprotein(AFP)≥400 ng/ml was an independent risk factor for affecting the survival of patients with advanced HCC(HR>1,P<0.05),while the triple therapy and previous targeted drugs therapy were the protective factors for the survival of patients with advanced HCC(HR<1,P<0.05).In the observation group,4 patients had grade 3 adverse reactions,and the common adverse reactions were dyspepsia(14.8%).One case of grade 3 adverse reactions occurred in control group,and there was no statistically significant difference in the incidence of adverse reactions between the two groups(P=0.639).Conclusion SBRT combined with camrelizumab and apatinib is a safe and effective treatment for advanced HCC with significant clinical effect and controllable adverse reactions.

Objective: To investigate the association between gestational diabetes mellitus (GDM) and preterm birth subtypes. Methods: Based on the cohort of pregnant women in Anqing Prefectural Hospital, the pregnant women who received prenatal screening in the first or second trimesters were recruited into baseline cohorts; and followed up for them was conducted until delivery, and the information about their pregnancy status and outcomes were obtained through electronic medical record system and questionnaire surveys. The log-binomial regression model was used to explore the association between GDM and preterm birth [iatrogenic preterm birth, spontaneous preterm birth (preterm premature rupture of membranes and preterm labor)]. For multiple confounding factors, the propensity score correction model was used to compute the adjusted association. Results: Among the 2 031 pregnant women with a singleton delivery, the incidence of GDM and preterm birth were 10.0% (204 cases) and 4.4% (90 cases) respectively. The proportions of iatrogenic preterm birth and spontaneous preterm birth in the GDM group (n=204) were 1.5% and 5.9% respectively, while the proportions in non-GDM group (n=1 827) were 0.9% and 3.2% respectively, and the difference in the proportion of spontaneous preterm birth between the two groups was significant (P=0.048). Subtypes of spontaneous preterm were further analyzed, and the results showed that the proportions of preterm premature rupture of membranes and preterm labor in the GDM group were 4.9% and 1.0% respectively, while the proportions in the non-GDM group were 2.1% and 1.1% respectively. It showed that the risk of preterm premature rupture of membranes in GDM pregnant women was 2.34 times (aRR=2.34, 95%CI: 1.16-4.69) higher than that in non-GDM pregnant women. Conclusions: Our results showed that GDM might increase the risk of preterm premature rupture of membranes. No significant increase in the proportion of preterm labor in pregnant women with GDM was found.

Objective: To investigate the influence of sleep fragmentation in infancy and toddler period on emotional and behavioral problems at the age of 6 years. Methods: Using a prospective cohort design, 262 children were extracted from mother-child birth cohort recruited from May 2012 to July 2013 in Renji Hospital, School of Medicine, Shanghai Jiao Tong University. Children's sleep and physical activities were assessed using actigraphy at 6, 12, 18, 24, and 36 months of age, from which the sleep fragmentation index (FI) at each follow-up point was calculated. Children's emotional and behavioral problems at 6 years of age were assessed using the strengths and difficulties questionnaire. Group-based trajectory model was applied to determine sleep FI in infancy and toddler period trajectory groups with Bayesian information criteria being used to determine the best fitting model. Children's emotional and behavioral problems between groups were examined with independent t test and linear regression models, etc. Results: A total of 177 children, with 91 boys and 86 girls, were included in the final analysis and were divided into 2 groups: high FI group (n=30) and low FI group (n=147). Compared with children in the low FI group, those in the high FI group presents with higher total difficulties score and higher hyperactivity or inattention score ((11.0±4.9) vs. (8.9±4.1), (4.9±2.7) vs. (3.7±2.3) scores, t=2.17, 2.23, both P<0.05, respectively), with the differences remaining significant after adjusting for covariates (t=2.08, 2.09, both P<0.05 respectively). Conclusion: High sleep fragmentation in infancy and toddler period is associated with more emotional and behavioral problems, especially hyperactivity or inattention problems, at 6 years of age.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.
