Da Chengqitang in Treatment of Sepsis： A Review / 中国实验方剂学杂志

Sepsis is a systemic inflammatory syndrome induced by infection and other factors， with the number of patients worldwide exceeding 10 million each year. The pathophysiological mechanism is of this disease complex. Sepsis is often accompanied by endotoxin translocation， gastrointestinal dysfunction， inflammatory cytokine activation， immune dysregulation， coagulation disorder， multiple organ function impairment and many other body imbalances， as well as systemic inflammation， apoptosis， oxidative stress injury and other cell damage mechanisms. This disease causes a heavy medical burden due to the difficult diagnosis and treatment and the poor prognosis. Great progress has been achieved in the diagnosis and treatment of sepsis with traditional Chinese medicine （TCM） and western medicine. The value of western medicine in the diagnosis and treatment of sepsis is limited due to antibiotic resistance， hormone abuse， and high medical costs. Sepsis is classified as a warm disease or typhoid fever in TCM. Da Chengqitang is a classical formula in the Treatise on Typhoid Fever to deal with the excess syndrome of Yang brightness Fu-organ. Modern medicine has proved that Da Chengqitang has the effect of inhibiting oxidative stress， reducing inflammation， and delaying apoptosis by improving gastrointestinal dynamics and regulating intestinal microecology. On the basis of the previous theoretical basis and the rich experience in the medication， medical practitioners have proposed a new therapeutic concept of using Da Chengqitang in combination with western drugs from a holistic view involving both bacteria and toxicity for treating both the symptoms and the root cause， which has a wide range of application. The article reviews the classical research and latest findings of Da Chengqitang in the treatment of sepsis， with a view to clarifying the mechanism and advantages of this formula in the adjuvant treatment of sepsis， exploring its potential efficacy， and providing timely， adequate， and scientific theoretical support for the promotion of this formula in the clinical practice.

Methodology and application of process analytical technology (PAT) for traditional Chinese medicine manufacturing:a review / 中国中药杂志

Owing to the advancement in pharmaceutical technology, traditional Chinese medicine industry has seen rapid development. Preferring conventional manufacturing mode, pharmaceutical enterprises of traditional Chinese medicine have no effective process detection tools and process control methods. As a result, the quality of the final products mainly depends on testing and the quality is inconsistent in the same batch. Process analytical technology(PAT) for traditional Chinese medicine manufacturing, as one of the key advanced manufacturing techniques, can break through the bottleneck in quality control of medicine manufacturing, thus improving the production efficiency and product quality and reducing the material and energy consumption. It is applicable to the process control and real-time release of advanced manufacturing modes such as intelligent manufacturing and continuous manufacturing. This paper summarized the general idea of PAT for traditional Chinese medicine manufacturing. Through the analysis of the characteristics and status quo of the technology, we summed up the methodology for the continuous application and improvement of PAT during the whole life-cycle of traditional Chinese medicine. The five key procedures(process understanding, process detection, process modeling, process control, and continuous improvement) were summarized, and the application was reviewed. Finally, we proposed suggestions for the technical and regulatory challenges in implementing PAT in traditional Chinese medicine industry. This paper aims to provide a reference for development and application of PAT in advanced manufacturing, intelligent manufacturing, and continuous manufacturing of traditional Chinese medicine industry.

Inhalation of Cananga odorata essential oil relieves anxiety behaviors in autism-like rats via regulation of serotonin and dopamine metabolism / 中西医结合学报

OBJECTIVE@#Anxiety is one of the most common symptoms associated with autistic spectrum disorder. The essential oil of Cananga odorata (Lam.) Hook. f. & Thomson, usually known as ylang-ylang oil (YYO), is often used in aromatherapy as a mood-regulating agent, sedative, or hypotensive agent. In the present study, the effects and mechanisms of YYO in alleviating anxiety, social and cognitive behaviors in autism-like rats were investigated.@*METHODS@#The prenatal valproic acid (VPA) model was used to induce autism-like behaviors in offspring rats. The effectiveness of prenatal sodium valproate treatment (600 mg/kg) on offspring was shown by postnatal growth observation, and negative geotaxis, olfactory discrimination and Morris water maze (MWM) tests. Then three treatment groups were formed with varying exposure to atomized YYO to explore the effects of YYO on the anxiety, social and cognitive behaviors of the autistic-like offspring through the elevated plus-maze test, three-chamber social test, and MWM test. Finally, the monoamine neurotransmitters, including serotonin, dopamine and their metabolites, in the hippocampus and prefrontal cortex (PFC) of the rats were measured using a high-performance liquid chromatography.@*RESULTS@#Offspring of VPA exposure rats showed autism-like behaviors. In the VPA offspring, medium-dose YYO exposure significantly elevated the time and entries into the open arms in the elevated plus-maze test, while low-dose YYO exposure significantly enhanced the social interaction time with the stranger rat in session 1 of the three-chamber social test. VPA offspring treated with YYO exposure used less time to reach the platform in the navigation test of the MWM test. YYO exposure significantly elevated the metabolism of serotonin and dopamine in the PFC of VPA offspring.@*CONCLUSION@#YYO exposure showed the effects in alleviating anxiety and improving cognitive and social abilities in the offspring of VPA exposure rats. The role of YYO was related to the regulation of the metabolism of serotonin and dopamine. Please cite this article as: Zhang N, Wang ST, Yao L. Inhalation of Cananga odorata essential oil relieves anxiety behaviors in autism-like rats via regulation of serotonin and dopamine metabolism. J Integr Med. 2023; 21(2): 205-214.

The Cochrane Handbook was used to evaluate the risk of bias in the included studies. Data analysis was conducted using RevMan 5.3 software.@*RESULTS@#Totally 19 RCTs with 2,331 participants were included in this review. Results showed that in improving arrhythmia (13 RCTs, n=1,877, RR=0.37, 95%CI 0.25 to 0.52, P<0.00001), the treatment group was superior to the control group. In terms of reducing left ventricular end-diastolic diameter (LVEDD, 2 RCTs, n=128, MD=-0.79, 95%CI -0.93 to -0.65, P<0.00001) and left ventricular end systolic diameter (LVESD, 2 RCTs, n=128, MD=-0.58, 95%CI -0.82 to -0.35, P<0.00001), the treatment group was also better than the control group. In reducing myocardial enzymes such as creatine kinase (CK) [(3 RCTs, n=256, SMD=-0.80, 95%CI -1.16 to -0.44, P<0.0001), (2 RCTs, n=126, SMD=-0.62, 95%CI -0.98 to -0.26, P=0.0007)], the treatment group was superior to the control group.@*CONCLUSION@#Shengmai San has a positive effect on the treatment of cardiotoxicity from anthracyclines. However, in the future, it is still necessary to conduct high-quality RCTs to verify its efficacy.

Protective Mechanism of Electroacupuncture on Peripheral Neurotoxicity Induced by Oxaliplatin in Rats / 中国结合医学杂志

OBJECTIVE@#To study the effect of electroacupuncture (EA) on oxaliplatin-induced peripheral neuropathy (OIPN) in rats.@*METHODS@#Male Sprague-Dawley rats were equally divided into 3 groups using a random number table: the control group, the OIPN group, and the EA (OIPN + EA) group, with 10 rats in each. The time courses of mechanical, cold sensitivity, and microcirculation blood flow intensity were determined. The morphology of the dorsal root ganglion (DRG) was observed by electron microscopic examination. The protein levels of nuclear factor E2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and the transient receptor potential (TRP) protein family in DRGs were assayed by Western blot.@*RESULTS@#EA treatment significantly reduced mechanical allodynia and cold allodynia in OIPN rats (P<0.01). Notably, oxaliplatin treatment resulted in impaired microcirculatory blood flow and pathomorphological defects in DRGs (P<0.01). EA treatment increased the microcirculation blood flow and attenuated the pathological changes induced by oxaliplatin (P<0.01). In addition, the expression levels of Nrf2 and HO-1 were down-regulated, and the TRP protein family was over-expressed in the DRGs of OIPN rats (P<0.01). EA increased the expression levels of Nrf2 and HO-1 and decreased the level of TRP protein family in DRG (P<0.05 or P<0.01).@*CONCLUSION@#EA may be a potential alternative therapy for OIPN, and its mechanism may be mainly mediated by restoring the Nrf2/HO-1 signaling pathway.

Mechanism of Traditional Chinese Medicine in Treating Depressive-related Syndromes Based on Intestinal Flora： A Review / 中国实验方剂学杂志

The depressive state， as an emotional disorder， has common symptoms of lack of interest， self-denial， unresponsiveness， unwillingness to communicate， and even extreme misanthropy or suicidal tendency. The depressive state involves a variety of diseases， such as depression， post-stroke depression， postpartum depression， irritable bowel syndrome， major depression， and schizophrenia， which affects the treatment effect and prognosis of the disease， seriously reduces the quality of life and increases the economic burden of patients. At present， the mechanism of depressive state is complex， and the pathophysiological mechanism is unclear. The mechanism of depressive state may be related to abnormal expression of monoamine neurotransmitters， neuronal damage， changes in transduction pathways， hyperactivity of the hypothalamic-pituitary-adrenal （HPA） axis， release of inflammatory cytokines， etc. An increasing number of studies in recent years have confirmed that the occurrence of depression is closely related to intestinal flora disorder， and they interact with each other. Traditional Chinese medicine （TCM） is effective in preventing and treating depressive state with few adverse reactions and a low recurrence rate. TCM also has the effect of regulating the homeostasis of intestinal flora. At the same time， intestinal flora affects the absorption and efficacy of active components of Chinese medicine through metabolic transformation. With the development of microecology， in-depth studies are conducted on the effect of intestinal flora on the occurrence and development of depressive state and brain-gut axis. Intestinal flora has become another potential target for the study of TCM treating depressive state. Starting from the theory and clinical practice of TCM， this paper summarized the mechanism of TCM in treating depressive state by Chinese medicine monomers， compound prescriptions， and acupuncture based on the theory of intestinal flora in recent years. This paper provided information for the profound study of the pathogenesis of depressive state and the scientific connotation of TCM in treating depressive state and ideas for the systematic exploration of the microbiological basis of symptom changes.

Danggui Buxuetang in Malignant Tumor： A Review / 中国实验方剂学杂志

The occurrence and development of malignant tumors seriously affect the survival time and quality of life of people all over the world， and finding proper treatment methods has been a focus for doctors. Especially in recent years， traditional Chinese medicine （TCM） has developed and attracted the attention of doctors and patients. From the perspective of TCM syndrome differentiation and treatment， deficiency and stasis are the most fundamental causes of malignant tumors， and supplementing deficiency and removing stasis can be regarded as the basic criteria of TCM treatment of malignant tumors. TCM prescriptions can treat diseases by means of multiple components and multiple targets， with the characteristics of slight side effect and high efficacy， safety and cost performance， as well as easiness to be accepted and taken. As a classic recipe for invigorating Qi and generating blood， Danggui Buxuetang consists of Astragali Radix -Angelicae Sinensis Radix 5∶1. It has excellent effects in anti-tumor， bone marrow suppression after chemotherapy， immune function decline， anemia， heart and cerebral vessels protection， blood deficiency-led fever， diabetes， anti-atherosclerosis， anti-fatigue， anti-radiation， myocardial ischemia alleviation， inhibition of platelet aggregation， liver damage， etc. In addition， with many active anti-tumor ingredients， Danggui Buxuetang can exert anti-tumor effects via acting on multiple targets in different binding sites. However， there has been a lack of reviews on the role of Danggui Buxuetang in malignant tumors so far. Therefore， in this paper， the functions of Danggui Buxuetang in malignant tumors were reviewed. Besides， molecular docking technology was used to analyze the main active anti-tumor ingredients and action targets of Danggui Buxuetang.

Material Attribute Research in Quality Control of Traditional Chinese Medicine Pills： A Review / 中国实验方剂学杂志

As intelligent production of traditional Chinese medicine （TCM） has been inevitable， informatization and automation of the production process have become the precondition for realizing intelligent manufacturing of TCM， of which the accumulation of critical material attribute and the critical quality attribute are the basis. The study of material properties is of great significance to achieve the quality control of the final product in the process， but there is a lack of systematic induction and summary of the research on the attribute of TCM pills. Therefore， the authors analyzed and summarized the attributes of raw materials， excipients and intermediates in the pill unit process according to the classification of powder properties， rheological properties and texture properties. What’s more， the impact of material attributes on the quality of the final product was summarized. Besides， this review summarized the attribute characterization techniques involved in the pill process and provided some suggestions for the characterization of product quality attributes. Finally， based on the concept of quality by design （QbD）， the authors proposed that the study of material attribute should be combined with process analytical technology （PAT）， and the focus of drug quality control should be moved forward to guide equipment upgrading， so as to realize intelligent continuous manufacturing of TCM pills.

Clinical Research on Treatment of Benign Prostatic Hyperplasia with Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

Benign prostatic hyperplasia （BPH）， a common disease in urology and andrology， is mainly manifested as enlarged prostate glands， bladder outlet obstruction， and lower urinary tract symptoms（LUTS）， which seriously affects the quality of life of middle-aged and elderly men. This disease falls into the categories of "retention of urine" and "prostatic hypertrophy" in traditional Chinese medicine （TCM）. In recent years，many doctors have put forward their understandings of BPH based on academic classics and their clinical experience. Clinical research on the treatment of BPH with TCM has become increasingly abundant. The basic pathogenesis of BPH lies in the disturbance of Qi transformation in the bladder and poor blood circulation due to kidney Qi deficiency in the aged. The disease is located in the kidney and the bladder and is related to the dysfunction of the lung and the kidney. It is basically characterized by deficiency in origin and excess in superficiality. A large number of clinical research reports have proved that TCM is efficient in alleviating the clinical symptoms of BPH patients， improving their quality of life， reducing the volume of the prostate， and decreasing postoperative complications. In addition， the external treatment methods of TCM， such as acupuncture therapy， moxibustion， hot water bathing， acupoint application， anal suppository， and enema therapy， are also widely used in clinical practice， demonstrating the diverse ways of TCM in treating BPH. TCM and western medicine complement each other's advantages in the treatment of BPH， thus enhancing the clinical efficacy and reducing the occurrence of long-term complications. This study reviewed the etiology， pathogenesis， and treatment progress of BPH with TCM in recent years， and summarized the current research status. From three aspects of producing high-quality clinical research， standardizing the clinical diagnosis and treatment of TCM， and combining cutting-edge research to explore the mechanism of TCM， it provided suggestions for clinical research on the treatment of BPH with TCM to promote the development and application of TCM in the treatment of this disease.

Antitumor Effect and Mechanism of Rutin： A Review / 中国实验方剂学杂志

The morbidity and mortality of cancer have been on the rise， making it atop the list of human health threats. It has been a conundrum of global magnitude. As the side effects of chemotherapeutics seriously affect the life quality of cancer patients， it is urgent to find effective anti-cancer drugs with small toxic and side effects. In recent years， the anti-cancer effects of traditional Chinese medicine have attracted the interest of scholars. Owing to the improvement of medical research， an increasing number of anti-cancer components with small toxic and side effects have been extracted from traditional Chinese medicine. Rutin， a unique flavonoid in Chinese medicinals and many plants， proves to inhibit the proliferation of breast cancer， colon cancer， lung cancer， and prostate cancer cells. In addition， rutin alone or in combination with other therapeutic drugs can regulate a variety of signaling pathways and signal mediators of inflammation， apoptosis， autophagy， and angiogenesis， thereby suppressing tumor progression. Moreover， it can also alleviate the drug resistance of tumors and the side effect of chemotherapeutics. Nevertheless， it is limited by the low bioavailability and low solubility， to which nano delivery system turns to be a solution. At the moment， the anti-cancer potential of rutin and the molecular targets of it against various cancers have not been summarized and comprehensively analyzed. Therefore， the authors retrieved articles on the anti-cancer effects of rutin in recent years， summed up the mechanisms and molecular targets， and discussed relevant drug delivery systems and the safety， aiming at laying a theoretical foundation for further development and application of the flavonoid.

Anti-tumor Mechanism of Active Ingredients of Glycyrrhizae Radix et Rhizoma and Its Combined Use in Anti-tumor Treatment： A Review / 中国实验方剂学杂志

As a traditional Chinese medicinal material， Glycyrrhizae Radix et Rhizoma has been extensively used in various formulae. According to modern pharmacological research， it has anti-tumor， anti-inflammatory， anti-viral， liver-protecting， anti-heart failure， immunoregulatory， and anti-fibrosis effects. Caused by the interaction of various factors， cancer features complex pathogenesis. It is a global challenge and one of the main causes of death in China. Statistics show that the morbidity and mortality of malignant tumors have been on the rise， particularly for the young， which threaten the health of human beings. At the moment， radiotherapy and chemotherapy are the main countermeasures. Most clinical anti-tumor drugs demonstrate non-selective toxicity. To be specific， they damage normal cells while killing tumor cells， thus injuring vital organs. In addition， long-term medication will reduce the sensitivity of tumor cells. However， traditional Chinese medicine， which is characterized by treatment based on syndrome differentiation， multiple components， and multiple targets， is superior in the treatment of tumor. Studies have shown that the combination of anti-tumor drugs with Chinese medicine can not only enhance the anti-tumor effect but also alleviate toxicity. Therefore， it has been a research hotspot to develop anti-tumor drugs based on traditional Chinese medicine. In recent years， major headway has been made in the research on active ingreddients of Glycyrrhizae Radix et Rhizoma in anti-liver cancer， anti-breast cancer， anti-lung cancer， and anti-colon cancer and the combination with other drugs for anti-tumor. On this basis， we summarized the mechanisms of active ingredients of Glycyrrhizae Radix et Rhizoma in inducing apoptosis， interfering with cell cycle， inducing autophagy， inhibiting glycolysis， regulating immunity， and modulating miRNA and signaling pathways， as well as the combination with other drugs in anti-tumor efficiency， toxicity reduction， and sensitivity enhancement， hoping to lay a theoretical basis for the further development and clinical application of active ingredients of Glycyrrhizae Radix et Rhizoma.

Analysis of Pulmonary Fibrosis Animal Models Based on Clinical Characteristics in Traditional Chinese Medicine and Western Medicine / 中国实验方剂学杂志

This paper collated the western medicine and traditional Chinese medicine （TCM） diagnostic criteria of pulmonary fibrosis （PF） based on its clinical characteristics and relevant literature reports and summarized the inductive agents， methods， objects， and mechanisms for replicating the PF animal models as well as their respective advantages and disadvantages. By analyzing the consistency of symptoms among successfully modeled animal models with the clinical characteristics in TCM and western medicine， we found that the intratracheal injection of bleomycin was the most frequently employed method for modeling， and the resulting outcomes were very similar to clinical characteristics in TCM and Western Medicine. Besides， considering the time-saving process， high stability， good repeatability， and low cost， such method was suitable for the rapid screening of drugs. The second preferred method was intraperitoneal injection of paraquat， which exhibited the advantages of high degree of consistency with clinical characteristics of PF caused by paraquat poisoning， low cost， high success rate， and easy operation， which allowed it to be suitable for exploring the mechanism of paraquat poisoning and developing the antidotes. The existing PF animal models shared a fairly high degree of consistency in symptoms with patients diagnosed as having PF in western medicine. However， the criteria for TCM syndrome differentiation remained unclear， and the animal models failed to reflect TCM pathogenesis. It is necessary to establish more accurate TCM diagnostic criteria that focus on syndrome differentiation and reveal TCM etiology and pathogenesis and carry out more experiments concerning TCM syndromes of PF in the future， so as to better treat PF with integrated TCM and Western Medicine.

Exploring the incidence characteristics of KOA based on the theory of "bone-restoration and tendon-softening" / 国际生物医学工程杂志

Knee osteoarthritis (KOA) is a kind of degenerative osteoarthrosis, which usually involves articular cartilage, subchondral bone, meniscus and quadriceps femoris, which is equivalent to the change of "tendon" in traditional Chinese medicine. The occurrence and development of the change of "tendon" can be explained by the theory of "bone-restoration and tendon-softening" in traditional Chinese medicine. If the force line of the lower limb of the knee joint is normal, it can be indicated by "bone-restoration" in traditional Chinese medicine, that is, the blood around the knee joint runs smoothly, and the "tenons" such as meniscus, ligaments, cartilage, etc. are softened by the blood. This condition of the knee joint can be manifested by the balance of the surrounding soft tissue state. If the force line of the lower limb of the knee joint changes, showing a medial offset and misalignment of the knee joint, it can be indicated by "bone is out of alignment" in traditional Chinese medicine, that is, the structure of the soft tissue around the knee joint and its mechanical characteristics have changed. This condition of the knee joint can be manifested by "the tendons lose their flexibility". In this paper, the theories of modern biomechanics and "bone-restoration and tendon-softening" in traditional Chinese medicine were comprehensively analyzed, the characteristics of the "tenons" when knee osteoarthritis occurs were analyzed, and the characteristics of the occurrence and development of knee osteoarthritis from the perspective of Chinese and Western medicine were discussed.

The effect of Dachengqi Decoction and enteral nutrition on the recovery of gastrointestinal function in patients with gastric cancer / 中国实用护理杂志

Objective:To explore the effect of Dachengqi Decoction and enteral nutrition on the recovery of gastrointestinal function in patients with gastric cancer.Methods:From September 2018 to September 2019, 100 patients with gastric cancer undergoing radical gastrectomy in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine were selected as the research objects, and were divided into observation group and control group according to the random number table method, each group contained 50 cases. Among them, the control group was given routine diet before operation to provide pre adaptation of enteral nutrient solution; the observation group was added with Dachengqi Decoction on the basis of routine diet. The recovery of gastrointestinal function, plasma motilin (MTL), serum gastrin (GAS) and gastrointestinal complications were observed and compared between the two groups.Results:There were 3 cases of abdominal distention and diarrhea in the control group, 1 case of diarrhea and 1 case of nausea and vomiting in the control group. The total incidence of gastrointestinal complications was 16% (8/50). There was 1 case of abdominal distention and 1 case of diarrhea in the observation group, and the total incidence of gastrointestinal complications was 4%(2/50). The difference between the two groups was statistically significant ( χ2 value was 4.000, P<0.05). In the observation group, the time of first bowel sounds, exhaust time and defecation time were (26.12 ± 5.32) h, (25.49 ± 4.49) h, (32.63 ± 4.31) h, respectively, which were significantly shorter than those in the control group (32.24 ± 6.41) h, (46.74 ± 6.14) h, (49.51 ± 6.28) h, and the difference was statistically significant ( t value was 5.195, 19.754, 15.671, P<0.05). The plasma MTL and serum gas in the observation group were (346.54 ± 18.58) ng/L, (123.44 ± 6.19) ng/L. After operation, the results were (247.24 ± 11.40) ng/L, (85.46 ± 5.12) ng/L. The difference was statistically significant ( t value was 97.793, 250.990, P<0.05). The plasma MTL and serum gas of the control group before operation were (344.63±16.65) ng/L and (122.53 ± 6.35) ng/L respectively. After operation, the results were (205.84±10.21)ng/L, (64.79±5.24) ng/L. The difference was statistically significant ( t value was 152.390, 367.823, P<0.05). The levels of plasma MTL and serum gas in the observation group were significantly higher than those in the control group ( t value was 19.129, 19.95, P<0.05). Conclusions:The modified Dachengqi Decoction and the pre adaptation of enteral nutrition solution are helpful to reduce the occurrence of various gastrointestinal complications after gastric cancer operation and promote the rapid recovery of gastrointestinal function, which may be related to the promotion of the secretion of MTL and gas.

Animal model analysis of secretory otitis media based on characteristics of clinical symptoms of traditional Chinese and Western medicine / 中国中药杂志

Based on the characteristics of clinical symptoms of secretory otitis media in traditional Chinese and Western medicine,by reference to clinical diagnostic criteria,efforts were made to analyze and establish the Western medical diagnostic criteria and traditional Chinese medicine( TCM) syndrome differentiation criteria for secretory otitis media,and summarize the modeling methods and model characteristics of secretory otitis media animal models. According to the clinical diagnostic criteria and symptom characteristics,the coincidence degree between the existing animal models and clinical symptoms was evaluated,and its advantages and disadvantages were defined. On the basis of the statistical results,there were fewer methods for modeling secretory otitis media animal models,and only a specific relevant pathogenic mechanism could be revealed. Among them,the model with a higher coincidence degree was genetic engineering technology modeling and injection into the middle ear vesicles. The two modeling methods of bacterial factors highly coincided with the clinical symptoms of Western medicine,but both failed to reflect the TCM syndrome type. Therefore,establishing an animal model that simultaneously reflects the characteristics of clinical symptoms of secretory otitis media in traditional Chinese and Western medicine,and improving the evaluation criteria of secretory otitis media based on animal models are the main tasks of future studies on secretory otitis media.

Research on feedforward control method of mixing process for compound Danshen Dripping Pills based on quality by design(QbD) / 中国中药杂志

The mixing process is one of the key operation units for solid preparation of traditional Chinese medicine. The physical properties such as particle size, density and viscosity of the mixture are key factors that need to be controlled, which will directly affect the performance of the preparation molding process and product quality. Subsequent dripping process performance and appearance qua-lity of dripping pills will be affected by dynamic viscosity of materials in the mixing process. Based on this, with mixing process of compound Danshen dripping pills as the object, a feedforward control method for the dripping pill mixing process was established based on the concept of quality by design(QbD). Firstly, critical quality attribute(CQA)-dynamic viscosity, critical material attributes(CMAs)-the moisture content of compound Danshen extract, average molecular weight of polyethylene glycol 6000 and critical process parameter(CPP)-mixing temperature were identified through the analysis of properties for multiple batches of the raw materials and excipients as well as technological mechanism. Then the Box-Behnken experimental design was used to establish the regression model among CMA, CPP and CMA(R■=0.972 0, RMSE =16.24) to obtain the design space. Finally, through the verification of three batches within the design space, the mixing process temperature was adjusted according to the properties of the raw materials and exci-pients to achieve accurate control of the dynamic viscosity attribute. The relative deviation between the actual dynamic viscosity value and the target value was less than 3.0 %. The feedforward control of the mixing process of compound Danshen dripping pills was rea-lized in this study, which can contribute to improving quality consistency of the mixing process intermediates, simultaneously provide a reference for the research on the process quality control of other Chinese medicine dripping pills.

Effect of Siwu decoction on the radiation injury of Zebrafish blood system / 中华放射医学与防护杂志

Objective:To observe the effect of Chinese herbal compound Siwu decoction (SW) on radiation injury of zebra fish blood system, and to clarify whether zebra fish is a suitable model for this study. Methods:Totally 72 of 4-month-old adult male zebra fish ( Danio Rerio) with body weight ranging from 0.14 to 0.20 g were used in all the experiments, where 36 zebra fish were taken to observe the hemodynamic changes after radiation, and the other 36 zebra fish were used to study the intervention effect of Siwu decoction on the blood injury after radiation. Zebra fish was irradiated with 20 Gy of 60Co gamma-rays at a dose rate of 97.33 cGy/min. For the hemodynamic study, the peripheral blood and whole kidney marrow cells (WKMCs)of irradiated zebra fish and non irradiated control were collected on days 7, 14 and 30 after irradiation, respectively, and the cell number was detected by flow cytometry. For the Siwu decoction treatment, 36 zebra fish were randomly divided into non-irradiation group, irradiation group, SW2 000 group ( Siwu decoction was diluted by 2 000-fold) and SW5 000 group ( Siwu decoction was diluted by 5 000-fold). Siwu decoction was given on the second day after irradiation. Then the peripheral blood and WKM cells of zebra fish were collected at 7 d after irradiation for further analysis. Results:After irradiation, the dynamic of blood development of zebra fish were obviously changed with the most blood cell ablation at 7 d post-irradiation. The total number of peripheral blood cells and WKM cells decreased by 26% and 52%( t=4.535, 28.987, P<0.05), the number of myeloid monocytes, lymphocytes, and red blood cells in the WKM decreased by 46%, 79% and 33%( t=18.457, 66.900, 9.872, P<0.05), and the number of precursor cells decreased by 49% ( P>0.05). The numbers of these blood cells were partly recovered at 14 d after irradiation and returned to the normal level at 30 d after irradiation. In comparison with irradiation alone group, the numbers of WKM cells, myeloid monocytes, progenitor cells, lymphocytes and red blood cells increased by 57%, 125%, 81% and 35%, respectively ( t=12.128, 21.594, 15.473, 4.594, P<0.05), and peripheral red cells did not increase significantly in the SW5 000 group after irradiation. However, SW2 000 had no significant influence on radiation injury of zebra fish blood cells ( P>0.05). Conclusions:Radiation injury of the blood system of zebra fish could be recovered at a month after irradiation, and this radiation damage could be partly intervened by Siwu decoction at a suitable concentration, which provides a reference for the study of blood system regulation of traditional Chinese medicine.
