RESUMO

ObjectiveTo observe the clinical efficacy and safety of Tengfu Jiangya tablets combined with valsartan/amlodipine in the treatment of grade 2 hypertension with liver Yang hyperactivity syndrome. MethodAccording to a randomized,double-blind,and placebo parallel control method,288 patients with grade 2 hypertension with liver Yang hyperactivity from 7 subcenters were included. They were randomly divided into an observation group (144 cases) and a control group (144 cases),and then treated with Tengfu Jiangya tablets combined with valsartan/amlodipine and placebo combined with valsartan/amlodipine,respectively. The efficacy was evaluated after four weeks of intervention. During the experiment,the safety indicators and adverse reaction events of the subjects were recorded for safety evaluation,and the efficacy indicators and TCM syndrome scores were recorded for effectiveness evaluation. Sensitivity analysis was also conducted on the statistical results of the main efficacy indicators such as blood pressure (BP) compliance rate to ensure the accuracy of the analysis results. 88 groups of blood samples from each of the treatment and control groups were included as test subjects. Fasting blood samples were collected from the patients in the clinical trial on the day before and after medication,and enzyme linked immunosorbent assay (ELISA) was performed on the treated serum. The levels of arachidonic acid (AA),thromboxane B2 (TXB2),and prostaglandin E2 (PGE2) in the serum of the patients before and after treatment were measured to explore the regulation of inflammatory factors in the body by Tengfu Jiangya tablets. ResultA total of 271 patients (133 in the observation group and 138 in the control group) completed the trial. There was no statistically significant difference before and after treatment in such safety indicators as the blood routine (white blood cells,red blood cells,and platelets),urine routine (urinary protein and urinary red blood cells),alanine aminotransferase,aspartate aminotransferase,creatinine,urea,and abnormal electrocardiogram,and no serious adverse reactions were observed. After four weeks,the systolic blood pressure (SBP) difference and diastolic blood pressure (DBP) difference of patients in the observation group were greater than those in the control group(P<0.01). According to the criteria for determining the antihypertensive effect,the overall response rate in the observation group[89.47%(119/133)] was higher than that in the control group[57.97%(80/138)] (Z=2.593,P<0.01). The SBP compliance rate was 61.65%(82/133) and 37.68%(52/138) in the observation group and control group, respectively. The DBP compliance rate in the observation group was 78.20%(104/133),while in the control group it was 55.07%(76/138). The overall BP compliance rate in the observation group was 48.12%(64/133),while in the control group it was 23.19%(32/138). The BP compliance rates in the observation group were all significantly higher than those in the control group(χ2=15.571,16.236,18.404,P<0.01). According to the criteria for evaluating the therapeutic effect of TCM syndrome integration,the overall response rate of the observation group[57.89%(77/133)] was higher than that of the control group[38.41%(53/133)] (Z=-3.172,P<0.01).Compared with those before treatment, the levels of serum AA and TXB2 in the two groups were significantly decreased after treatment (P<0.01), and the level of PGE2 in the observation group was significantly increased (P<0.01). Compared with those of the control group after treatment, the levels of AA and TXB2 in the observation group were significantly decreased, while the level of PGE2 was significantly increased (P<0.01). The results suggest that Tengfu Jiangya tablets can effectively reduce inflammatory factors,reduce the production of inflammatory mediators,and thus prevent the occurrence of inflammatory reactions in the treatment of patients with grade 2 hypertension. ConclusionTengfu Jiangya tablets can more effectively reduce patients' SBP and DBP,improve their BP compliance rates,and improve their TCM syndromes in the treatment of grade 2 hypertension with liver Yang hyperactivity. Its clinical application is safe. Tengfu Jiangya tablets has outstanding clinical efficacy and can be used as an effective intervention method for the treatment of grade 2 hypertension with liver Yang hyperactivity syndrome.

RESUMO

Objective:To evaluate the performance of an artificial intelligent (AI)-based automated digital cell morphology analyzer (hereinafter referred as AI morphology analyzer) in detecting peripheral white blood cells (WBCs).Methods:A multi-center study. 1. A total of 3010 venous blood samples were collected from 11 tertiary hospitals nationwide, and 14 types of WBCs were analyzed with the AI morphology analyzers. The pre-classification results were compared with the post-classification results reviewed by senior morphological experts in evaluate the accuracy, sensitivity, specificity, and agreement of the AI morphology analyzers on the WBC pre-classification. 2. 400 blood samples (no less than 50% of the samples with abnormal WBCs after pre-classification and manual review) were selected from 3 010 samples, and the morphologists conducted manual microscopic examinations to differentiate different types of WBCs. The correlation between the post-classification and the manual microscopic examination results was analyzed. 3. Blood samples of patients diagnosed with lymphoma, acute lymphoblastic leukemia, acute myeloid leukemia, myelodysplastic syndrome, or myeloproliferative neoplasms were selected from the 3 010 blood samples. The performance of the AI morphology analyzers in these five hematological malignancies was evaluated by comparing the pre-classification and post-classification results. Cohen′s kappa test was used to analyze the consistency of WBC pre-classification and expert audit results, and Passing-Bablock regression analysis was used for comparison test, and accuracy, sensitivity, specificity, and agreement were calculated according to the formula.Results:1. AI morphology analyzers can pre-classify 14 types of WBCs and nucleated red blood cells. Compared with the post-classification results reviewed by senior morphological experts, the pre-classification accuracy of total WBCs reached 97.97%, of which the pre-classification accuracies of normal WBCs and abnormal WBCs were more than 96% and 87%, respectively. 2. The post-classification results reviewed by senior morphological experts correlated well with the manual differential results for all types of WBCs and nucleated red blood cells (neutrophils, lymphocytes, monocytes, eosinophils, basophils, immature granulocytes, blast cells, nucleated erythrocytes and malignant cells r>0.90 respectively, reactive lymphocytes r=0.85). With reference, the positive smear of abnormal cell types defined by The International Consensus Group for Hematology, the AI morphology analyzer has the similar screening ability for abnormal WBC samples as the manual microscopic examination. 3. For the blood samples with malignant hematologic diseases, the AI morphology analyzers showed accuracies higher than 84% on blast cells pre-classification, and the sensitivities were higher than 94%. In acute myeloid leukemia, the sensitivity of abnormal promyelocytes pre-classification exceeded 95%. Conclusion:The AI morphology analyzer showed high pre-classification accuracies and sensitivities on all types of leukocytes in peripheral blood when comparing with the post-classification results reviewed by experts. The post-classification results also showed a good correlation with the manual differential results. The AI morphology analyzer provides an efficient adjunctive white blood cell detection method for screening malignant hematological diseases.

RESUMO

Objective:To explore the diagnostic value of the toxicant and drug detection in clinical poisoning diseases and analyze the clinical characteristics of patients with positive poison test.Methods:This study was a multicenter retrospective cohort study. Sampling and clinical information data were collected between October 1, 2020 and September 30, 2022 from 41 tertiary hospitals in and around Jiangsu province. The clinical characteristics of patients with positive toxicology tests were analyzed, and the correlation between the drug sampling situation and the test results was analyzed..Results:A total of 895 patients with clinical diagnosis or suspected poisoning were enrolled in this study. Among them, 652 patients had positive results, accounting for 72.85%. Among all positive patients, 506 patients were exposed to a single poison and 147 patients were exposed to multiple poisons. The top three poisons were pesticide herbicides (202 cases, 30.98%), sedative and psychotropic drugs (151 cases, 23.16%), and pesticide insecticides (97 cases, 14.88%). Among 541 patients with clear exposure history, the positive rate was 78.19%, and among 354 patients with unclear exposure history, the positive rate was 64.69%. The top three poisons (drugs) of patients with unclear exposure history were sedative and psychotropic (82, 12.58%), herbicide (26, 3.99%), and rodenticide (22, 3.37%). Patients who admitted to hospital for unexplained consciousness disorder, abnormal blood coagulation function and multiple organ dysfunction were more likely to obtain positive poison test results.Conclusions:There is uncertainty in the exposure history of poisoning diseases, so it is necessary to improve the detection of toxic substances as soon as possible. Toxicant testing should be considered when patients have impaired consciousness, abnormal coagulation function and multiple organ dysfunction.

RESUMO

ObjectiveThrough a randomized, double-blind, double-simulation, positive-control, multicenter design, this study aimed to analyze the relationship between the dosage, efficacy, and safety of Pudilan anti-inflammatory oral liquid in treating acute pharyngitis/tonsillitis in adults caused by bacterial infection and validate the regulatory effect of Pudilan anti-inflammatory oral liquid on inflammatory markers such as serum amyloid A (SAA), C-reactive protein (CRP), white blood cells (WBC), neutrophil percentage (NE%), and erythrocyte sedimentation rate (ESR), thereby exploring the feasibility of using Pudilan anti-inflammatory oral liquid as a substitute for antibiotics in the treatment of infectious diseases and providing a basis for rational clinical medication. MethodUsing a stratified randomized, double-blind, double-simulation, positive-control, multicenter design, 220 participants were enrolled from nine centers. The participants were randomly divided into three groups at 1∶1∶1 — a Pudilan anti-inflammatory oral liquid 20 mL group (73 cases), a Pudilan anti-inflammatory oral liquid 10 mL group (73 cases), and a control group (amoxicillin group, 74 cases). The treatment course was 7 days. The study observed parameters including the total effective rate of sore throat, onset and disappearance time of sore throat, health status score, treatment time, and inflammation markers. Result①Dataset division: The 211 cases were included in the full analysis dataset (FAS), 208 cases were included in the per-protocol dataset (PPS), and 218 cases were included in the safety dataset (SS). ② Efficacy evaluation: There were statistically significant differences (P<0.05) in the comparison of the three groups regarding the total effective rate of sore throat, disappearance time of sore throat, and health status. Both the 20 mL and 10 mL groups were non-inferior to the control group, and there was a statistically significant difference between the 20 mL and 10 mL dosage groups (P<0.05). There was no statistically significant difference in the comparison of onset time of sore throat among the groups. CRP, WBC, and NE% of patients in all three groups significantly decreased on the 7th day of treatment compared with those before treatment (P<0.01). ③Safety evaluation: Adverse events mainly occurred in various examination indicators. There were no statistically significant differences in the comparison between groups, and no adverse reactions or serious adverse events occurred. ④Economic evaluation: The increased cost of the 10 mL and 20 mL dosage groups was entirely justified as compared with that in the control group. When comparing the 10 mL and 20 mL dosage groups, the 10 mL dosage group was deemed less advantageous. ConclusionPudilan anti-inflammatory oral liquid can be used alone as an alternative to antibiotics in the treatment of acute pharyngitis/tonsillitis caused by bacterial infection. It demonstrates good safety and can lower inflammation markers such as CRP, WBC, and NE%, suggesting its potential to reduce the body's inflammatory response. Its mechanism of action may be related to its multi-target regulatory mechanism.

RESUMO

ObjectiveTo confirm the clinical efficacy and safety of Yishen Yangxin Anshen tablets in the treatment of insomnia (heart-blood deficiency and kidney-essence insufficiency syndrome). MethodA randomized block, double-blind, placebo-controlled, multi-center clinical trial design method was adopted, and a total of 480 patients with insomnia due to deficiency of heart blood and insufficiency of kidney essence (treatment group-control group 3∶1) from seven hospitals (Guang'anmen Hospital, China Academy of Chinese Medical Sciences, The First Clinical Hospital, Jilin Province Academy of Traditional Chinese Medicine(TCM), The Second Affiliated Hospital of Liaoning University of TCM, The First Affiliated Hospital of Henan University of Chinese Medicine, Henan Province Hospital of TCM, Hebei General Hospital, The First Hospital of Hunan University of Chinese Medicine) were enrolled. The treatment group was given Yishen Yangxin Anshen tablets and the control group received placebo tablets (4 tablets/time, 3 times/day, 4 weeks of administration, 4 weeks of follow-up after drug withdrawal). The sleep dysfunction rating scale (SDRS) score, pittsburgh sleep quality index (PSQI) score, TCM, polysomnography (PSG) indicators from four hospital (Guang'anmen Hospital, China Academy of Chinese Medical Sciences, Henan Province Hospital of TCM, Hebei General Hospital, The First Hospital of Hunan University of Chinese Medicine), and other efficacy indicators were compared between the two groups before and after treatment. Through general physical examination, laboratory examination, and observation of adverse events, the safety of the drugs was evaluated. ResultThe baseline indexes of the two groups showed no significant difference and thus the two groups were comparable. After treatment, the total score of SDRS in the treatment group was lower than that in the control group (P<0.01). After drug withdrawal for 4 weeks, the total score of SDRS demonstrated no significant change in the treatment group as compared with that at the end of treatment, indicating that the rebound change of curative effect was not obvious. After treatment, the total score of PSQI in the treatment group decreased as compared with that in the control group (P<0.01), and the change of total score of PSQI in the treatment group was statistically significant (P<0.05) after drug withdrawal for 4 weeks but small, indicating that the rebound change of curative effect was not obvious. After treatment, the total effective rate about the TCM symptoms in the treatment group was higher than that in the control group (χ2=137.521,P<0.01). After treatment, the disappearance rates of single indexes in the treatment group, such as difficulty in falling asleep, easily waking up after sleeping, early awakening, short sleep time, dreamfulness, palpitation, forgetfulness, dizziness, mental fatigue, and weakness of waist and knee, increased compared with those in the control group (P<0.01). After treatment, the treatment group demonstrated fewer awaking times (AT), longer total sleep time (TST), lower ATA/TST ratio, and higher sleep efficiency (%) than the control group (P<0.05). No abnormal value or aggravation related to drugs was observed in either group. The incidence of adverse events in the treatment group and the control group was 5.57% and 8.40% respectively. No serious adverse events or adverse events leading to withdrawal happened in either group. ConclusionYishen Yangxin Anshen tablets is effective and safe for patients with insomnia of deficiency of heart-blood and insufficiency of kidney-essence.

RESUMO

@#Objective     To investigate the influence of prior percutaneous coronary intervention (PCI) on the outcome of coronary artery bypass grafting (CABG). Methods     Clinical data of 5 216 patients from Jiangsu Province CABG registry who underwent primary isolated CABG from 2016 to 2019 were retrospectively analyzed. Patients were divided into a PCI group (n=673) and a non-PCI group (n=4 543) according to whether they had received PCI treatment. The PCI group included 491 males and 182 females, aged 62.6±8.2 years, and the non-PCI group included 3 335 males and 1 208 females, aged 63.7±8.7 years. Multivariable logistic regression and propensity score matching (PSM) were used to compare 30-day mortality, incidence of major complications and 1-year follow-up outcomes between the two groups. Results     Both in original cohort and matched cohort, there was no statistical difference in the 30-day mortality [14 (2.1%) vs. 77 (1.7%), P=0.579; 14 (2.1%) vs. 11 (1.6%), P=0.686], or the incidence of major complications (myocardial infarction, stroke, mechanical ventilation≥24 h, dialysis for new-onset renal failure, deep sternal wound infection and atrial fibrillation) (all P>0.05). The rate of reoperation for bleeding in the PCI group was higher than that in the non-PCI group [19 (2.8%) vs. 67 (1.5%), P=0.016; 19 (2.8%) vs. 7 (1.0%), P=0.029]. Both in original cohort and matched cohort, there was no statistical difference in 1-year survival rate between the two groups [613 (93.1%) vs. 4 225 (94.6%), P=0.119; 613 (93.1%) vs. 630 (95.2%), P=0.124], while the re-admission rate in the PCI group was significantly higher than that in the non-PCI group [32 (4.9%) vs. 113 (2.5%), P=0.001; 32 (4.9%) vs. 17 (2.6%), P=0.040]. Conclusion     This study shows that a history of PCI treatment does not significantly increase the perioperative mortality and major complications of CABG, but increases the rate of cardiogenic re-admission 1 year postoperatively.

At present, the issues regarding multi-center clinical trials of new drugs of traditional Chinese medicine(TCM) remain: the lack of agreement on the content and scope of the ethical review among the ethics committee members of the center and the participating units results in repeated review, which leads to a time-consuming ethical review process. Moreover, the review capabilities of the ethics committees of various research centers are uneven, which is not necessarily beneficial to the protection of subjects' rights and safety. In view of the existing problems, to improve the efficiency of ethical review of multi-center clinical trials of new drugs of TCM and avoid repeated reviews, the TCM Clinical Evaluation Professional Committee of Chinese Pharmaceutical Association organized experts to formulate the "Consensus on collaborative ethical review of multi-center clinical trials of new drugs of TCM(version 1.0)"(hereinafter referred to as "Consensus"). The "Consensus" is formulated in accordance with the requirements of relevant documents such as but not limited to "the opinions on deepening the reform of the evaluation and approval system to encourage the innovation of pharmaceutical medical devices", "the regulations of ethical review of biomedical research involving human subjects". The "Consensus" covers the scope of application, formulation principles, conditions for the ethics committee of the center, sharing of ethical review resources, scope and procedure of collaborative review, rights and obligations, etc. The aims of the "Consensus" is to preliminarily explore and establish a scientific and operable ethical review procedure. Additionally, on the basis of fully protecting the rights and interests of the subjects, a collaborative ethical review agreement needs to be signed to clarify the ethical review responsibilities of all parties, to avoid repeated review, and to improve the efficiency and quality of ethical review in multi-center clinical trials of new drugs of TCM.

RESUMO

Objective:To explore the performance of the commonly used whole blood C-reactive protein (CRP) detection systems and give related recommendation on the performance requirements of detection systems.Methods:A total of 7 540 venous blood samples from 26 maternal, child and children′s hospitals were collected to conduct this multi-center study on the analytical performance of 5 commonly used whole blood CRP detection systems from March to April in 2019. The blank check, carryover, repeatability, intermediate precision, linearity, sample stability, influence of hematocrit/triglyceride/bilirubin, comparison with SIEMENS specific protein analyzer and trueness were evaluated. The 5 systems included BC-5390CRP autohematology analyzer, AstepPLUS specific protein analyzer, Ottoman-1000 Automated Specific Protein POCT Workstation, i-CHROMA Immunofluorometer equipment Reader and Orion QuikRead go detecting instrument. The 5 systems were labeled as a, b, c, d and e randomly.Results:Within the 5 systems, all values of blank check were less than 1.00 mg/L, the carryovers were lower than 1.00%. The repeatability of different ranges of CRP concentrations including 3.00-10.00, 10.00-30.00 and>30.00 mg/L were less than 10.00%, 6.00% and 5.00%, respectively, and the intermediate precision was less than 10.00%. The linearity correlation coefficients of the 5 systems were all above 0.975, while the slope was within 0.950-1.050. Whole blood samples were stable within 72 hours both at room temperature (18-25 ℃) and refrigerated temperature (2-8 ℃). The CRP results were rarely influenced by high triglyceride or bilirubin, except for the immmunoturbidimetric test based on microparticles coated with anti-human CRP F(ab) 2 fragments. When triglyceride was less than 15.46 mmol/L, the deviation of CRP was less than 10.00%. When bilirubin was less than 345.47 μmol/L, the deviation of CRP was less than 10.00%. CRP was more susceptible to Hct on the systems without Hct correction. The deviation of CRP between different Hct dilution concentration and 40% dilution concentration can reach as high as 67.48%. The correlation coefficients ( r) of 5 systems were all more than 0.975 in the range of 0-300.00 mg/L compared with Siemens specific protein analyzer. All systems passed the trueness verification using the samples with specified values of 12.89 and 30.60 mg/L. Conclusion:The performance of 5 systems can basically meet the clinical needs, but it is suggested that the whole blood CRP detection system without automatic Hct correction should be modified manually.

RESUMO

Objective@#This study collected and analyzed data from patients with microtia in multiple clinical centers to obtain the incidence characteristics of microtia in Chinese.@*Methods@#Data from 746 patients with microtia were collected from six hospitals, including theThird Hospital of Hebei Medical University, Hunan Provincial People′s Hospital, the Second Hospital of Hebei Medical University, Weihai Municipal Hospital, West China Hospital Sichuan University, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from January 2016 to December 2017. These data included the results of physical examination and the results of auxiliary examination such as electrocardiogram, chest CT, and abdominal ultrasound. Then, the accompanying malformations of the microtia were statistically analyzed and discussed. Data were entered and processed using SPSS 19.0 statistical software. The relationship between microtia deformities and associated malformations was analyzed by Pearson χ2 test. P<0.05 was considered statistically significant.@*Results@#A total of 746 patients with microtia were included, including 513 males and 233 females, aged 5-27 years old. There were 678 cases of unilateral microtia, 68 cases of bilateral microtia; 128 cases of Ⅰ degree, 564 cases of Ⅱ degree, and 54 cases of Ⅲ degree. In addition, 336 cases (45%) were associated with dysplasia of other systems. Detected anomalies were 321 cases of the ear, face, and neck, 261 cases of musculoskeletal system and 76 cases of cardiovascular system, 30 cases of anomalies of the urogenital system, eye, 27 cases of respiratory system, 7 cases of central nervous system, 5 case of digestive system and 1case of diaphragmatic hernia. The proportion of male and female with microtia was 47.0% (241/513) and 40.8% (95/233), respectively, and there was no significant difference in between (χ2=2.493, P=0.114); The composition ratios of unilateral and bilateral associated malformations were 45.7% (310/678) and 38.2% (26/68 ), and there was no significant difference in between (χ2=1.400, P=0.237); The composition ratios of Ⅰ, Ⅱ, Ⅲ degree-associated malformations were 39.8% (51/128), 42.6% (240/564), and 83.3% (45/54), and the difference was statistically significant (χ2= 34.794, P<0.001).@*Conclusions@#Microtia has significant clinical heterogeneity with a higher proportion of associated malformations. A higher incidence of associated deformities in patients with severe microtia was observed. Systematic examination is required, which will be helpful to clinical therapy and etiology analysis.

RESUMO

OBJECTIVE@#To explore the clinical therapeutic effect of light and heat of moxibustion for knee osteoarthritis (KOA).@*METHODS@#A total of 216 patients with KOA were randomized into a traditional moxibustion group (72 cases, 8 cases dropped off), a moxibustion light group (72 cases, 9 cases dropped off) and a moxibustion heat group (72 cases, 10 cases dropped off).The special light-heat separation moxibustion cup was applied, the patients in the traditional moxibustion group received the treatment of moxibustion, the patients in the moxibustion light group received the treatment of moxibustion light and the patients in the moxibustion heat group received the treatment of moxibustion heat. The acupoint selection of the three groups was Neixiyan (EX-LE 4), Dubi (ST 35) and Zusanli (ST 36), the treatment was given 20 min each time, 3 times a week, 4 weeks were required totally, and the follow-up surveys were made 4 and 8 weeks after treatment. The scores of Western Ontario and McMaster University osteoarthritis index (WOMAC) and visual analogue scale (VAS) were observed before treatment, after 2 and 4 weeks of treatment, 4 and 8 weeks after treatment. The therapeutic effects were evaluated according to the criterion of patient global assessment (PGA) after 4 weeks of treatment and 8 weeks after treatment.@*RESULTS@#Compared with before treatment, the pain scores, stiffness scores, physical function scores and total scores of WOMAC were reduced after 2, 4 weeks of treatment and 4 weeks after treatment in the three groups (<0.05). The pain scores, stiffness scores, physical function scores and total scores of WOMAC were reduced 8 weeks after treatment in the traditional moxibustion group and the moxibustion heat group (<0.05). The stiffness score, physical function score and total score of WOMAC were reduced 8 weeks after treatment in the moxibustion light group (<0.05). The pain score, physical function score and total score of WOMAC in the traditional moxibustion group after 4 weeks of treatment were lower than the moxibustion light group (<0.05). Compared with before treatment, the VAS scores were reduced after 2, 4 weeks of treatment and 4 , 8 weeks after treatment in the three groups (<0.05). The improvement rates in the traditional moxibustion group and the moxibustion heat group after 4 weeks of treatment and 8 weeks after treatment were superior to the moxibustion light group (<0.05).@*CONCLUSION@#The light and heat of moxibustion have therapeutic effect for KOA, and the therapeutic effect of moxibustion heat is superior to moxibustion light.
