ABSTRACT

Objective@#To explore the social functioning characteristics of children with co ocurrence of attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) for intervention reference.@*Methods@#The Chinese Version of Swanson Nolan and Pelham, Version IV Scale-Parent Form(SNAP-IV), the Chinese Version of Weiss Functional Impairment Scale-Parent(WFIRS-P), and the Questionnaire-Children with Difficulties (QCD) were applied to 192 children with ADHD, 243 children with co occurrence of ADHD and ODD, who firstly visited the Department of Children Psychological Health of Zhuhai Maternal and Child Health Care Hospital, and 118 healthy control children from a school in Zhuhai.@*Results@#The scores of attention deficit factor in SNAP-Ⅳ scale of children in three groups were[1.9(1.7, 2.1), 1.8(1.6, 1.9), 1.0(0.6, 1.2)], the scores of hyperactive impulsivity were[1.8(1.4, 2.1), 1.6(1.1, 1.8), 0.7(0.2, 1.0)] the scores of oppositional defiant were[1.6(1.5, 1.9), 1.0(0.8,1.1), 0.8(0.5, 1.0)], the differences were statistically significant( H=268.44, 237.97, 418.66, P <0.01). The dimensions and total scores of the three groups of children s WFIRS-P scale were family[0.8(0.6, 1.1), 0.6(0.3, 0.8), 0.3(0.1, 0.6)]; learning and school[0.8(0.5, 1.1), 0.8(0.5, 1.0), 0.3(0.1, 0.5)]; life skills[1.0(0.7, 1.2), 0.8(0.6, 1.0), 0.6(0.4, 0.8)]; self management [1.0(0.3, 1.0), 0.7(0.3, 1.0), 0.3(0.0, 0.7)]; social activities [0.7(0.4, 1.0), 0.6(0.3, 0.9), 0.3(0.0, 0.4 )]; adventure activities[0.3(0.2, 0.5), 0.2(0.1, 0.4), 0.1(0.0, 0.2)]; the total score[0.8(0.6, 1.0), 0.6(0.5, 0.8), 0.4( 0.2 , 0.6)], the difference between the groups was statistically significant( H=108.82, 122.45, 60.17, 40.58, 96.17, 76.57, 138.30, P <0.01). The difference between the QCD scale scores of children in the three groups was statistically significant[30.0( 24.0 , 37.0), 32.0(27.0, 40.0), 47.0(37.0, 52.3), H=124.65, P <0.01). Multiple regression analysis showed that attention deficit, and oppositional defiant symptoms were associated with both the total WFIRS-P score and the QCD score of children( R 2= 0.40 , 0.25, P <0.05).@*Conclusion@#Children with co occurrence of ADHD and ODD have more severe deficits in all dimensions of social functioning than children with ADHD, which might be associated with attention deficit and oppositional defiant symptoms.

ABSTRACT

@#Eutrophils are the first innate immune cells to reach the site of inflammation. Neutrophils produce neutrophil extracellular traps (NETs) that can quickly capture and limit the spread of pathogens, facilitating the removal of pathogens and their debris. Neutrophils in the oral cavity are specifically transformed from circulating neutrophils in the blood, and the number of NETs released by oral neutrophils is much higher than that of circulating neutrophils, thus better maintaining the balance of the oral microenvironment. As a bimorphic fungus, only the mycelium phase of Candida albicans can induce NETs, which is related to the neutrophils' ability to sense the size of pathogenic microorganisms through neutrophil elastase. However, spherical Staphylococcus aureus are much smaller than Candida albicans, and they can still induce NETs. Porphyromonas gingivalis, as one of the microorganisms in the periodontitis complex, induces fewer NETs than Streptococcus oralis and Actinomycetes, which are two common oral microorganisms, and there may be a mechanism allowing them to escape neutrophilic immunity in the early stage of periodontitis. Although the two main pathways of NET production have been studied in detail, the mechanisms involved in the induction of NETs by different microorganisms, especially from oral neutrophils, are not well understood. This review describes the mechanism of the immune effects of pathogenic microorganisms on neutrophil NETs in the oral cavity, providing a reference for the search for therapeutic targets and the development of key drugs for treating oral infectious diseases.

ABSTRACT

Objective:To observe the optimal time interval of multiple short-term hyperthermia in tongue squamous carcinoma Cal-27 cells, and investigate the role of Notch signaling pathway in hyperthermia-induced apoptosis of Cal-27 cells.Methods:Cal-27 cells were placed into a 42℃ incubator for 45 min, and the second hyperthermia was performed at 6 h,12 h, 24 h, 48 h and 72 h later, respectively. Cell proliferation capacity was detected by CCK-8 assay at 0 h, 12 h and 24 h after the end of hyperthermia. After determining the optimal time interval of hyperthermia, multiple cycles of hyperthermia were performed, and the effects of hyperthermia on the proliferation and apoptosis of Cal-27 cells were detected by CCK-8 assay and flow cytometry, respectively. The changes in the expression of Notch1, Jagged1 and hairy and enhancer of split homolog-1 (Hes1) mRNA and proteins were analyzed by real-time reverse transcription PCR (qRT-PCR) and Western blot. All data were expressed as mean±SD. Two-group comparison was performed by one-way ANOVA.Results:Hyperthermia at 42℃ for 45 min every 12 h consistently inhibited the proliferation of Cal-27 cells ( P<0.05). Compared with the control group, hyperthermia in the experiment group significantly inhibited the proliferation and induced the apoptosis of Cal-27 cells after 7 cycles of hyperthermia ( P<0.05), and the expression levels of Notch1, Jagged1 and Hes1 mRNA and proteins in the hyperthermia group were significantly down-regulated (all P<0.05). Conclusions:The optimal time interval of hyperthermia to inhibit the proliferation of tongue squamous cells carcinoma Cal-27 cells is 12 h. Hyperthermia might induce the apoptosis of Cal-27 cells by inhibiting the Notch signaling pathway.

ABSTRACT

Objective@#To construct an evaluation index system of public health emergency preparedness capacity in county-level centers for disease control and prevention (CDC), so as to provide the evidence for improving the public health emergency preparedness capacity in county-level CDC.@*Methods@#An index system framework was created based on review of health emergency policies, laws and regulations released in China from 2003 to 2023. The importance, sensitivity and accessibility of indicators were scored and screened through two rounds of Delphi expert consultations, and the weights of indicators were calculated using precedence charts. The efficiency of Delphi expert consultations was evaluated using the active coefficient, authority coefficient and coordination coefficient. @*Results@#Eighteen experts participated in consultations, including 9 men, 15 with educational levels of master degree and higher, 12 with preventive medicine or public health as the specialty, and 12 with deputy senior professional titles and higher. The active coefficients of two rounds of consultations were 100.00% and 94.44%, and the authority coefficients were 0.83 and 0.84, respectively. The coordination coefficients of secondary and tertiary indicators during the second round consultation were 0.341 and 0.241, which were both higher than those during the first round (both P<0.05). The final evaluation index system included 8 primary indicators, 21 secondary indicators and 58 tertiary indicators. Among primary indicators, health emergency organization and management (0.203 1), health emergency team building (0.203 1) and financial support for health emergency (0.203 1) had the highest weights, and of secondary indicators, completion degree of health emergency administration regulations (initial weight/global weight: 0.750 0/0.152 3), health emergency team building (0.750 0/0.152 3) and financial support for emergency (0.750 0/0.152 3) had the highest weights, while among tertiary indicators, defining the duty of health emergency administration sectors had the highest weight (0.750 0/0.114 2). @*Conclusion@#The created evaluation index system is feasible for evaluation of the public health emergency preparedness capacity in county-level CDC.

ABSTRACT

Objective:To investigate the expression of hsa_circ_0000437 in the serum of patients with gastric cancer and its clinical value.Methods:The serum samples from 80 patients (57 males and 23 females) with pathologically confirmed gastric cancer (GC), 50 gastric benign disease (28 males and 22 females) and 80 healthy controls (46 males and 34 females) were collected from October 2018 to December 2020 in Affiliated Hospital of Nantong University.Serum samples from 35 of 80 gastric cancer patients after operation were collected. The expression of serum hsa_circ_0000437 was determined by real-time fluorescent quantitative PCR (RT-qPCR). Serum carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA 199) and carbohydrate antigen 724 (CA724) were determined by chemiluminescence method.Comparisons of serum hsa_circ_0000437 between groups were performed by Mann-Whitney U test.The correlation between serum expression of hsa_circ_0000437 in gastric cancer patients and its clinical pathological characteristics was performed by χ 2 test.Receiver operating characteristic (ROC) curve and the area under the curve of ROC (AUC) were used to evaluate their diagnosis efficiency. Kaplan-Meier survival curve analysis was used to analyze the relationship between the expression level of serum hsa_circ_0000437 and the prognosis of patients. Results:The relative expression of hsa_circ_0000437 in GC, gastric benign disease, healthy controls were 2.252 (1.235, 4.765), 1.598(1.139, 1.982) and 1.000 (0.818, 1.385) respectively.The relative expression of hsa_circ_0000437 in GC was significantly higher than that in gastric benign disease ( P<0.001) and healthy controls ( P<0.001). The difference between gastric benign disease and healthy controls was also statistically significant ( P<0.001).The differences of serum hsa_circ_0000437 expression in GC patients between T stage, N stage, and tumor differentiation were statistically significant. The AUC of hsa_circ_0000437, CEA, CA199 and CA724 in GC patients were 0.863, 0.619, 657 and 0.608 respectively compared with healthy controls. The AUC of above four-parameter panel was 0.892 and the sensitivity was up to 97.5% (78/80). Kaplan-Meier survival curve showed that the overall survival rate of patients with high serum hsa_circ_0000437 expression was significantly lower than that of patients with low expression ( P=0.008). Conclusion:Serum hsa_circ_0000437 could be a biomarker for the auxiliary diagnosis and prognosis of GC.

ABSTRACT

Objective@#For computer-aided Chinese medical diagnosis and aiming at the problem of insufficient segmentation, a novel multi-level method based on the multi-scale fusion residual neural network (MF2ResU-Net) model is proposed.@*Methods@#To obtain refined features of retinal blood vessels, three cascade connected U-Net networks are employed. To deal with the problem of difference between the parts of encoder and decoder, in MF2ResU-Net, shortcut connections are used to combine the encoder and decoder layers in the blocks. To refine the feature of segmentation, atrous spatial pyramid pooling (ASPP) is embedded to achieve multi-scale features for the final segmentation networks.@*Results@#The MF2ResU-Net was superior to the existing methods on the criteria of sensitivity (Sen), specificity (Spe), accuracy (ACC), and area under curve (AUC), the values of which are 0.8013 and 0.8102, 0.9842 and 0.9809, 0.9700 and 0.9776, and 0.9797 and 0.9837, respectively for DRIVE and CHASE DB1. The results of experiments demonstrated the effectiveness and robustness of the model in the segmentation of complex curvature and small blood vessels.@*Conclusion@#Based on residual connections and multi-feature fusion, the proposed method can obtain accurate segmentation of retinal blood vessels by refining the segmentation features, which can provide another diagnosis method for computer-aided Chinese medical diagnosis.

ABSTRACT

With the rapid aging of the population, elderly epilepsy probably becomes one of the most common forms of epilepsy. Lacosamide, brivaracetam, eslicarbazepine acetate, and perampanel have been approved by the United States Food and Drug Administration and the European Medicines Agency for monotherapy and (or) adjunctive treatment of seizures in the last few years. This review summarizes the efficacy and tolerability of third-generation anti-seizure medications in elderly epilepsy patients and introduces the effects of anti-seizure medications on cognitive function and mood, as well as drug-drug interactions, aiming to provide a reliable basis for clinicians to choose third-generation anti-seizure medications.

ABSTRACT

Most anti-seizure medications do not change the course of epilepsy and are basically "symptomatic treatment". Even if a variety of new anti-seizure medications continue to come out, there are still more than 30% of patients develop drug-resistant epilepsy. Therefore, investigating new therapeutic targets and developing effective drugs to prevent or reverse the onset and progression of epilepsy are important goals of clinical and preclinical researches. Based on the current studies, to realize the transformation from anti-seizure to anti-epileptogenesis and disease-modifying therapy, it not only needs standardized animal models and biomarkers that can predict the epileptogenesis or progression but also needs sufficient patients, rigorous design schemes, and cutting-edge analysis methods to successfully transform preclinical research into clinical practice. There is no doubt that in the future, targeting various nerve injury pathways to achieve anti-epileptogenesis and disease-modifying therapy probably becomes a truly effective means of treating and preventing epilepsy.

ABSTRACT

OBJECTIVES@#To explore the effect of polydatin on the proliferation and apoptosis of acute monocytic leukemia cell line THP-1 and the possible mechanism.@*METHODS@#After THP-1 cells were treated with polydatin at gradient concentrations for 24 hours and 48 hours, their proliferation was determined by CCK-8 assay, and half maximal inhibitory concentration (IC50) was calculated. Logarithmically growing THP-1 cells were divided into two groups, a polydatin treatment group (treated with IC50 of polydatin) and a blank control group (treated without polydatin solution), and incubated for 48 hours. Cell apoptosis and cell cycle were measured by flow cytometry. The expression levels of PI3K, AKT, p-AKT, mTOR, p-mTOR, p70 S6K, and p-p70 S6K proteins were measured by Western blotting.@*RESULTS@#After treatment with polydatin, the proliferation of THP-1 cells was strongly inhibited, and the IC50 at 48 hours was 1 800 μmol/L. After treatment with 1 800 μmol/L polydatin solution for 48 hours, the apoptosis rate of THP-1 cells increased significantly compared with the blank control group (P<0.05). The cell cycle was arrested in the G0/G1 and S phases, with a significantly increased proportion of cells in the G0/G1 phase and a significantly decreased proportion of cells in the S phase, as compared with the blank control group (P<0.05). The expression levels of PI3K, AKT, p-AKT, mTOR, p-mTOR, p70 S6K, and p-p70 S6K proteins decreased significantly compared with the blank control group (P<0.05).@*CONCLUSIONS@#Polydatin can effectively inhibit the proliferation, block the cell cycle, and induce the apoptosis of THP-1 cells, which may be related to inhibition of the PI3K/AKT/mTOR signaling pathway.

ABSTRACT

The paper introduces professor ZHUANG Li-xing's clinical experience in treatment of intra-uterine residue and lochia after drug abortion. Professor ZHUANG believes that this disorder is related to "dysfunction of the thoroughfare vessel and the conception vessel, qi deficiency and blood stagnation, and retention of turbid qi in the uterus" in pathogenesis. The treating principle should focus on "regulating the functions of the thoroughfare vessel and the conception vessel, tonifying qi and eliminating stasis, as well as promoting qi movement". Besides Hegu (LI 4) and Sanyinjiao (SP 6), the acupoints are added from the conception vessel. The Daoqi Tongjing needling technique (the specific technique for directing qi and preserving essence) is exerted flexibly instead of traditional reinforcing and reducing technique of acupuncture to tonify qi and remove stasis.

ABSTRACT

Persistent pulmonary hypertension of the newborn(PPHN)is a disease that seriously endangers the life of the newborn caused by one or more factors.The causes mainly include respiratory distress syndrome, meconium aspiration syndrome, infection, congenital diaphragmatic hernia, etc.The pathogenesis of PPHN is still not completely clear, and neurobiochemical, internal environment, genetics and other factors are currently recognized as influencing factors.In recent years, with the rapid development and wide application of genetic testing technology, more and more studies have shown that the occurrence of PPHN may be related to the polymorphism and/or mutation of some genes.This article reviews the research progress of six gene loci that may be related to PPHN in order to provide reference for clinical research.

ABSTRACT

Objective:To report a case of germinated teeth of the left mandibular second molar diagnosed by cone-beam CT (CBCT), and to investigate its differential diagnosis, pathogenesis, and the application value of CBCT in the diagnosis of oral and maxillofacial diseases.Methods:One case of germinated teeth of the left mandibular second molar diagnosed according to oral general examination ad CBCT findings in Zhenjiang Stomatological Hospital, China in March, 2019 was included in this study. The characteristics and differential points of supernumerary cusp, fused teeth, geminated teeth and concresence of teeth were analyzed based on literatures.Results:CBCT examination showed that the number of mandibular dentition teeth was normal, there was a large area of low-density transmission area around the root of the left mandibular second molar. Three-dimensional reconstruction results revealed that the suspected supernumerary teeth were fused with the root of the left mandibular second molar. Sagittal projections showed that the suspected supernumerary teeth were located in the buccal side of the left mandibular second molar. Axial projections showed three separate root canal orifices at the level of pulp chamber floor, and the dentin of the two was connected. The suspected supernumerary teeth had an independent pulp cavity and a clear root canal, and fused with the distal root canal of the left mandibular second molar in the middle of the root to form a root canal. A "Y"-shaped structure was displayed on the sagittal projections. CBCT showed that the left mandibular second molar was a fused root. Based on oral clinical examination, the left mandibular second molar was confirmed to be a germinated tooth.Conclusion:CBCT is one of the most important means of oral auxiliary examination. It has significant advantages in the diagnosis of tooth abnormalities. It can help clinicians to make correct diagnosis and choose the appropriate treatment scheme. It has certain clinical significance and innovation.

ABSTRACT

Objective:To investigate the predictive value of estimated renal perfusion pressure (eRPP) for acute kidney injury (AKI) in severe multiple trauma patients.Methods:Severe multiple trauma patients were collected based on the inclusion criteria and exclusion criteria from the Trauma Center, the Third Xiangya Hospital, Central South University. Subsequently, patients were divided into the AKI group and non-AKI group according to the occurrence of AKI during 72 h admission to hospital. Further clinical information, ISS score, SOFA score, APACHE Ⅱ score, mean arterial pressure (MAP), central venous pressure (CVP) and intra-abdominal pressure (IAP) were collected, and eRPP were calculated. Additionally, the differences of parameters in the AKI group and non-AKI group were analyzed and logistic regression analysis was performed to identify the independent predicted risk factors for AKI. Finally, ROC curve was conducted to identify specificity, sensibility and best cut-off point.Results:A total of 173 severe multiple trauma patients were finally analyzed. Compared with the non-AKI group, the serum albumin [(32.21±5.20)g/L vs. (34.83±4.20)g/L, P =0.001] and 24 h urine output [(711.90±241.38)mL vs. (1 101.21±509.86)mL, P =0.001] were significantly lower and serum lactate [(2.80±0.96)mmol/L vs. (1.89±0.63)mmol/L, P<0.001], ISS score [(29.05±5.91) vs. (22.17±4.02), P <0.001], APACHEⅡ score [(38.84±21.47) vs. (31.45±18.24), P <0.001] and SOFA score [(5.26±2.08) vs. (3.14±1.34), P <0.001], in-hospital mortality (9.52% vs. 2.29%, P=0.038), and ICU stay [(8.43±6.46)d vs. (6.42±3.78) d, P =0.01) were significantly higher in the AKI group. Moreover, 6, 12 and 24 h of CVP and eRPP after admission were associated with the incidence of AKI. Logistic regression analysis showed that 24 h urine output, CVP and eRPP were the independent predictive factors (P <0.05) and 24 h of eRPP after admission applied a better predictive value of the incidence in AKI. Conclusions:24 h of eRPP might be the most suitable independent predictive factor for AKI in severe multiple trauma patients.

ABSTRACT

Diabetes is a worldwide public health problem that seriously threats human health. Long-term metabolic disorders, as the main cause of multi-system complications and death in the later stage of diabetes, can cause multi-system damage, leading to chronic progressive lesions in the eyes, kidneys, nerves, heart, blood vessels and other tissues and organs, as well as functional decline and failure. The low risk of side effects and new treatment strategies remain an area to be explored in clinical treatment of diabetes. Salviae Miltiorrhizae Radix et Rhizoma (SM) is one of the commonly used herbs in traditional Chinese medicine (TCM), with the main effect of activating blood circulation and removing blood stasis. In recent years, it has been found that SM shows good performance in lowering blood sugar and treating diabetes complications. Data mining information has also shown that the drugs of activating blood circulation and removing blood stasis are now common drugs in clinical treatment of diabetes, and SM has the highest use frequency, with significant curative effect. In addition, TCM is a kind of treatment with composite components and multiple targets, and so people are increasingly interested in its effective components and carry out extensive researches. This article summarized the experimental verification of SM extract and its components (tanshinone A, tanshinone B, tanshinone ⅡA, tanshinone I, protocatechuic aldehyde, polysaccharide, and total polyphenol acid) in various diabetes models in improving glucolipid metabolism, improving heart function in patients with diabetes, alleviating the motor and sensory deficits caused by diabetes, preventing the occurence of the diabetic retinopathy, recovery of liver and kidney structure and function damage in diabetic patients, and helping to resist high sugar-induced atrophic cavitation potential. It may inhibit hyperglycemia-induced vascular injury with polyol pathway activation, reduce the formation of advanced glycation end products, inhibit protein kinase C pathway activation and hexosamine pathway activation, and alleviate oxidative stress caused by excessive production of peroxides in mitochondrial electron transport chain during hyperglycemia to play a role of treatment, and provide reference for clinical application.

ABSTRACT

Objective:To explore the effects of Xintongtai (XTT) on traditional Chinese medicine (TCM) syndrome score and collagen fibers in vascular smooth muscle cells(VSMCs) of rabbits with atherosclerosis in the regulation of p38 mitogen-activated protein kinase (p38 MAPK)/activator protien-1 (AP-1)signaling pathway. Method:A total of 120 rabbits of SPF grade were randomly divided into the sham operation group, combined phlegm and blood stasis model group, rosuvastatin group, and low-, middle-, and high-dose XTT groups. The rabbit model of atherosclerosis due to combined phlegm and blood stasis was established by exposing them to high-fat diet and balloon injury. Following modeling, the corresponding drugs were administered by gavage for eight weeks (2.3, 4.6, 9.2 g·kg<sup>-1</sup> for low-, middle-, and high-dose XTT groups and 0.55 mg·kg<sup>-1 </sup>for rosuvastatin group). At the end of medication, the abdominal aorta was isolated and stained with htoxylin-eosin (HE) for observing the vulnerable plaque. Matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) were detected by immunohistochemistry (IHC). The collagen fiber decomposition in VSMCs was observed after Masson staining. The protein expression levels of p38 MAPK and AP-1 in aorta was assayed by Western blotting. The combined phlegm and blood stasis syndrome was scored based on TCM syndrome scoring scale. Result:Compared with the model group, XTT at each dose and rosuvastatin significantly decreased MMP-9 content, increased TIMP-1, down-regulated p38 MAPK protein expression, and weakened the nuclear translocation of AP-1 (<italic>P</italic><0.01). Compared with the low-dose XTT group, the middle- and high-dose XTT groups and rosuvastatin group exhibited obviously lowered MMP-9,elevated TIMP-1, down-regulated p38 MAPK protein expression, and diminished AP-1 nuclear translocation (<italic>P</italic><0.05,<italic>P</italic><0.01). The TCM syndrome scores of the middle- and high-dose XTT groups and rosuvastatin group were significantly improved as compared with that in the model group (<italic>P</italic><0.05,<italic>P</italic><0.01). The comparison with the low-dose XTT group revealed a remarkable improvement in TCM syndrome score of the middle- and high-dose XTT groups and rosuvastatin group (<italic>P</italic><0.01). As demonstrated by Masson staining, the smooth muscle fibers in the model group were arranged in disorder, accompanied by enhanced collagen decomposition, thinned fibrous cap, and increased plaque vulnerability. Compared with the model group, the VSMCs in each XTT group and rosuvastatin group were orderly arranged, manifested as decreased collagen fiber decomposition and increased plaque stability. Conclusion:XTT down-regulates the expression of p38 MAPK and MMP-9, increases the level of TIMP-1, reduces the nuclear translocation of AP-1, diminishes the decomposition of collagen fibers in VSMCs, and improves the score of combined phlegm and blood stasis syndrome. XTT alleviates arteriosclerosis due to combined phlegm and blood stasis by regulating p38 MAPK/AP-1 signaling pathway and downstream cytokines and stabilizing vulnerable plaques.

ABSTRACT

Assessment of the status property(boiling time) is a challenge for the quality control of extraction process in pharmaceutical enterprises. In this study, the pilot extraction process of Phellodendron chinense was used as the research carrier to develop an online near-infrared(NIR) quality control method based on the status property(boiling time). First, the NIR spectra of P. chinense were collected during the two pilot-scale extraction processes, and the status property(boiling time) was assessed by observing the state of bubbles in the extraction tank using a transparent window during the extraction process, which was then used as a reference standard. Based on the moving block standard deviation(MBSD) algorithm, the assessment model using online NIR spectra for boiling time during extraction process was established. In addition, the model was optimized as follows: standard normal variable(SNV) for spectral pretreatment, modeling band of 800-2 200 nm, and window size of 4. The results showed that, with 0.002 0 as the MBSD model threshold, the boiling time can be accurately assessed using online NIR spectra during extraction process. Furthermore, the principal component analysis-moving block standard deviation(PCA-MBSD) model was developed by our group to reduce the influence of online NIR spectral noise and background signal on the model, and the number of principal components was optimized into 2 in the PCA-MBSD model. The results showed that, with 0.000 075 as the PCA-MBSD model threshold, the boiling time can be accurately assessed using online NIR spectra during extraction process, with improved reliability. This study can provide a assessment method for boiling time during extraction process using online NIR spectra, which can replace the empirical judgment in manual observation, and realize the digitalization of the extraction process for big brand traditional Chinese medicine.

ABSTRACT

The physical properties of powder and granules are the critical quality attributes for the process control of Suhuang Zhike Capsules, a big brand traditional Chinese medicine. This paper took the production of 25 batches of real-world Suhuang Zhike Capsules dry extract powder and granules intermediates as the research object. Firstly, a method for testing the physical properties of Suhuang Zhike Capsules powder and granules with 19 physical indicators was established. The results showed that the granules of dry extract powder after granulation had a smaller particle size, wider particle size distribution range and poor fluidity, which easily caused the problem of over-limit capsule loading. Secondly, correlation analysis, principal component analysis and cluster analysis were used for mathematical statistics. The correlation analysis showed that the density of dry extract powder could affect the chroma and fluidity. At the same time, the particle size in the granules had a stronger effect on the chroma and fluidity than the density. The study also found that the particle size and hygroscopicity of dry extract powder were potentially key physical properties that affected the physical properties of granules. Furthermore, the results of principal component analysis and cluster analysis showed that the consistency of the physical properties between the dry extract powder and intermediate granules was relatively poor. To this end, similarity analysis was carried out, and the quality control method of powder and granules based on physical fingerprint was established. The results showed that the physical fingerprint similarity of 25 batches of dry extract powder was 0.639-0.976, and the physical fingerprint similarity of the gra-nules was 0.716-0.983. With the similarity of 0.85 as the threshold, the batches with abnormal physical properties could be identified. In this study, the process quality control method of Suhuang Zhike Capsules based on the physical properties of powder and granules was established finally, which realized the identification of abnormal batches, and provided a reference for the process quality control of Suhuang Zhike Capsules.

ABSTRACT

The chemical properties of characteristic components are significant to the manufacturing quality control of big brand traditional Chinese medicine. In this study, the Huangjing Zanyu Capsules were used as the research carrier to determine the content of five characteristic components including icraiin, emodin, schisandrin A, 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside, and osthole simultaneously by high-performance liquid chromatography(HPLC). The results showed that the chemical properties of five cha-racteristic components had a good linear relationship(r>0.999 9) within the quantitative range; the relative standard deviations(RSD) was 0.11%-2.0% and 0.25%-2.8% respectively for intra-day and inter-day precision; the RSD of repeatability was 1.8%-2.6%; the RSD of stability within 48 hours was 0.19%-2.8%, and the average recovery rate was 95.52%-100.1%, all meeting the requirements of pharmaceutical quantitative analysis. Additionally, the interval estimation method was used to directly reflect the distribution of samples with abnormal chemical properties of characteristic components, and the results showed ten samples were detected beyound the 95% control line of confidence level. Multivariate statistical process control(MSPC) method was used to monitor the abnormal samples of Huangjing Zanyu Capsules collectively, and the results showed that two samples were beyond the 95% control line of Hotelling's T~2 and three samples beyond the 95% control line of squared prediction error(SPE), indicating consistent quality control of Huangjing Zanyu Capsules. In conclusion, the proposed method is not only accurate and efficient but also a compensation for the traditional single-component quality control method, providing a scientific basis for the quality control in manufacturing process of Huangjing Zanyu Capsules. Furthermore, it could also serve as a reference method for the quality control in manufacturing big brand traditional Chinese medicine.
