Treatment of rheumatoid arthritis by injection of sinomenine solid lipid nanoparticles under a fluorescence endoscopic laser confocal microscope / 中国中药杂志

A fluorescence endoscopic laser confocal microscope(FELCM) was used to direct the injection of sinomenine solid lipid nanoparticles(Sin-SLN) into the joint, and the in vitro effectiveness of Sin-SLN in the treatment of rheumatoid arthritis(RA) was evaluated. Sin-SLN was prepared with the emulsion evaporation-low temperature curing method. The Sin-SLN prepared under the optimal conditions showed the encapsulation efficiency of 64.79%±3.12%, the drug loading of 3.84%±0.28%, the average particle size of(215.27±4.21) nm, and the Zeta potential of(-32.67±0.84) mV. Moreover, the Sin-SLN demonstrated good stability after sto-rage for 30 days. The rabbit model of RA was established by the subcutaneous injection of ovalbumin and complete Freund's adjuvant. Five groups were designed, including a control group, a model group, a Sin(1.5 mg·kg~(-1)) group, a Sin-SLN(1.5 mg·kg~(-1)) group, and a dexamethasone(positive drug, 1.0 mg·kg~(-1), ig) group. The control group and the model group only received puncture treatment without drug injection. After drug administration, the local skin temperature and knee joint diameter were monitored every day. The knee joint diameter and the local skin temperature were lower in the drug administration groups than in the model group(P<0.05, P<0.01). FELCM recorded the morphological alterations of the cartilage of knee joint. The Sin-SLN group showed compact tissue structure and smooth surface of the cartilage. Enzyme-linked immunosorbent assay(ELISA) was employed to determine the serum le-vels of interleukin-1(IL-1) and tumor necrosis factor-α(TNF-α). The findings revealed that the Sin-SLN group had lower IL-1 and TNF-α levels than the model group(P<0.05, P<0.01). Hematoxylin-eosin(HE) staining was employed to reveal the pathological changes of the synovial tissue, which were significantly mitigated in the Sin-SLN group. The prepared Sin-SLN had uniform particle size and high stability. Through joint injection administration, a drug reservoir was formed. Sin-SLN effectively alleviate joint swelling and cartilage damage of rabbit, down-regulated the expression of inflammatory cytokines, and inhibited the epithelial proliferation and inflammatory cell infiltration of the synovial tissue, demonstrating the efficacy in treating RA.

PK/PD model of Chuanxiong gel plaster in treatment of rheumatoid arthritis / 中国中药杂志

In this experiment, the PK/PD fitting model of Chuanxiong(Chuanxiong Rhizoma) in the treatment of rheumatoid arthritis was established in the form of acupoint combined with external application gel paste. Firstly, the rheumatoid arthritis model was induced by ovalbumin, and the articular fluid of rabbits was extracted by microdialysis. The pharmacokinetic process of Chuanxiong in rabbit articular fluid was analyzed by UPLC-MS/MS, and the pharmacokinetic model was established. The pharmacodynamic effects of Chuanxiong on inflammatory factors IL-1β, TNF-α, and IL-6 were analyzed by enzyme-linked immunosorbent assay(ELISA). The pharmacodynamic model was established, and the PK/PD model was obtained by fitting the data of pharmacokinetics and pharmacodynamics. The results of pharmacokinetics showed that the concentration of ligustrolide A in the articular cavity by drug administration on classical acupoint Zusanli(ST 36) was higher than that by Yanglingquan(GB 34), which reflected the advantage of typical acupoint, while ligustrazine concentration was higher after administration through Yanglingquan than through Zusanli, which was different from the traditional acupoint theory. The results of pharmacodynamics showed that the drug had lag effect. The PK/PD model was constructed by fitting the data. When IL-1β was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=115.28C_e/(3 316.72+C_e), E=108.73C_e/(2 993.47+C_e), and E=101.34C_e/(3 028.51+C_e). When TNF-α was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=68.31C_e/(3 285.16+C_e), E=59.27C_e/(2 919.86+C_e), and E=53.61C_e/(2 862.87+C_e). When IL-6 was taken as the efficacy index, the PK/PD models of Chuanxiong in typical acupoint Zusanli group, atypical acupoint Yanglingquan group, and non-acupoint group were E=59.92C_e/(3 461.17+C_e), E=58.34C_e/(2 723.51+C_e), and E=49.17C_e/(2 862.76+C_e). The parameters showed that there were significant differences in E_(max), EC_(e50) and k_(eo). The analysis of data found that the PK/PD fitting effect of Zusanli, a typical acupoint, was the best, which proved that it was still the best site for drug administration. To sum up, it shows that there may be bidirectional selectivity between drugs and acupoints.

Exploring acupuncture treatment strategies for snoring based on meridian theory / 中国针灸

Starting from the perspective of meridian theory, this article briefly analyzes the meridian pathophysiology of snoring and the relationship between snoring and meridian theory. It proposes that acupuncture treatment for snoring should focus on regulating qi from the shaoyang meridians, harmonizing the spirit by the governor vessel, resolving phlegm through the three yang meridians, and harmonizing qi and blood from the yangming meridians. Additionally, attention is placed on both the root cause and the symptoms, the theory of "four seas". The ultimate goal is to promote the flow of meridian and qi-blood, improve symptoms such as nighttime snoring, poor sleep quality, and daytime sleepiness, and achieve the desired outcome of stopping snoring and ensuring restful sleep.

Application of single-arm objective performance criteria/performance goal in acupuncture-moxibustion clinical trials / 中国针灸

Due to various constraints, such as clinical implementation conditions and unique characteristics of acupuncture-moxibustion, some randomized controlled trials (RCTs) of acupuncture-moxibustion still suffer from relatively low quality and limited applicability. The single-arm objective performance criteria/performance goal can be considered as an ideal supplementary and alternative research approach to RCTs. In this paper, the feasibility of applying the single-arm objective performance criteria/performance goal in acupuncture-moxibustion clinical research is explored from the limitations of conducting acupuncture-moxibustion RCTs, the principles, the essential design considerations and key statistical steps. In addition, illustrative examples are provided. The objective is to offer insights into resolving practical difficulties in acupuncture-moxibustion clinical research.

Clinical thinking of acupuncture for snoring based on "disharmony qi leads to restlessness" / 中国针灸

This study summarizes the clinical thinking of acupuncture for snoring based on "disharmony qi leads to restlessness". According to the pathological characteristics of qi stagnation and blood stasis, phlegm dampness and internal obstruction in snoring patients, combined with the etiology, pathogenesis and location of the disease, the innovative viewpoint of "disharmony qi leads to restlessness" is proposed. It is believed that the key to snoring treatment lies in "regulating qi ". In clinical practice, acupuncture can directly regulate the qi of the disease's location, regulate the qi of the organs and viscera, and regulate the qi of the meridians to achieve overall regulation of the body's internal and external qi, smooth circulation of qi and blood, and ultimately achieve the therapeutic goal of harmonizing qi, stopping snoring, and improving sleep quality.

The clinical randomized controlled trials(RCTs) of Chinese patent medicine in the treatment of chronic obstructive pulmonary disease(COPD) were reviewed and analyzed to provide references for clinical research, guideline development, policy formulation, and quality improvement of clinical evidence. On the basis of the collection in the Traditional Chinese Medicine(TCM) Clinical Evidence Database System(EVDS), CNKI, Wanfang, SinoMed, Cochrane Library, PubMed, EMbase were searched for RCTs of Chinese patent medicine for COPD as a source of clinical evidence from database inception to December 31, 2019. The publication time, sample size, intervention and control measures, course of treatment, outcome indicators, and methodological quality of the trials were analyzed and evaluated. A total of 733 RCTs of Chinese patent medicine for COPD were included, among which 228 RCTs had a sample size higher than 100, accounting for 31.1% of total RCTs. Eighty-eight Chinese patent medicines were involved, including 40 oral medicines and 48 injections. A total of 327 RCTs mentioned intervention and control measures(Chinese patent medicine + conventional treatment vs conventional treatment), accounting for 43.0%. In addition, 94.40% of the RCTs reported the course of treatment, and 53.20% of the RCTs determined 8-14 d as the intervention course. The evaluation indicators adopted were numerous, among which physicochemical indicators(70.57%) and symptoms/signs(24.35%) were the most frequently employed. The operation of allocation concealment and blinding was not standard. Registration and the procedure related to ethics were mostly missing. The results indicate that there are prominent methodological problems in the clinical trials of Chinese patent medicine in the treatment of COPD, affecting the reliability and practicability of the trials. It is necessary to further standardize the design, implementation, and quality control of clinical trials of Chinese patent medicine in the treatment of COPD, highlight the clinical value of Chinese patent medicine for COPD, and improve the quality of evidence.

Clinical trials and evaluation of Chinese patent medicine for pneumonia / 中国中药杂志

The present study reviewed the clinical randomized controlled trials(RCTs) of Chinese patent medicine for pneumonia to provide references for clinical research, guideline development, and policy formulation, and promote the quality improvement of clinical evidence. On the basis of the collection in the Traditional Chinese Medicine(TCM) Clinical Evidence Database System(EVDS), CNKI, Wanfang, SinoMed were searched for RCTs of Chinese patent medicine for pneumonia from database inception to December 31, 2019. A total of 1 245 RCTs were included, involving 84 Chinese patent medicines, including 45 oral medicines and 39 injections. Specifically, 85.9% of RCTs had treatment course not exceeding 14 d; 43.3% of RCTs had a sample size of more than 100 cases and 6.1% of RCTs more than 200 cases; 13 types of interventions/controls were included in the RCTs, with Chinese patent medicine + western medicine vs western medicine as the top one used(32.6%). In outcome indicators, symptoms/signs(3 285) and physicochemical detection(2 066) were the most frequently applied. In the methodological evaluation, "allocation concealment" was not clearly described or mentioned in 71.2% of RCTs, and "blinding" in 23.9% of RCTs met the normative standards. Registration and research ethics were not clearly reported. There are many methodological deficiencies in terms of design and implementation in included RCTs, which may impact the reliability and practicability of the results of RCTs. Additionally, key standards were unclear(such as disease classification methods and selection of core outcome indicators). In conclusion, RCTs should give priority to the preciseness and scientificity of the protocol, strengthening quality control of the processes and accelerating the standardized research of key links.

Network pharmacological analysis and experimental verification of anti-inflammatory and analgesic effect of Zanthoxyli Pericarpium / 中国中药杂志

To explore the mechanism of anti-inflammatory and analgesic effect of Zanthoxyli Pericarpium based on network pharmacology and inflammatory or pain mouse models. The effective components of Zanthoxyli Pericarpium were screened out by TCMSP database. And their potential corresponding targets were predicted by PharmMapper software. The possible targets relating to inflammation and pain were mainly collected through DrugBank, TTD and DisGeNET databases. The "active ingredient-gene-disease" network diagram was constructed by Cytoscape 3.7.0 software. The network pharmacology results showed 5 potential effective compounds, which were related to 29 targets; 132 targets relating to inflammation and pain were screened out in the DrugBank, TTD and DisGeNET databases. The network analysis results indicated that the phosphatidylinositol 3-kinase catalytic subunit gamma isoform(PIK3 CG) gene may be the key to the anti-inflammatory and analgesic effect of Zanthoxyli Pericarpium. The anti-inflammatory and analgesic effects of essential oil extract and dichloromethane extract of Zanthoxyli Pericarpium were explored through the mouse model of inflammation induced by xylene or carrageenan and the mouse model of pain induced by acetic acid or formalin. The experimental results showed that essential oil extract and dichloromethane extract of Zanthoxyli Pericarpium could reduce xylene-induced ear swelling and carrageenan-induced paw swelling and decrease the number of writhing responses in mice induced by acetic acid and the licking foot time of mice in phase Ⅱ induced by formalin. Western blot results showed that Zanthoxyli Pericarpium extract could inhibit the expressions of PIK3 CG, phosphonated nuclear factor kappaB(p-NF-κB) and phosphonated p38(p-p38 MAPK) protein. The present study showed the anti-inflammatory and analgesic effect of Zanthoxyli Pericarpium through multiple components and targets, so as to provide a pharmacodynamic basis for the study of Zanthoxyli Pericarpium and its mechanism.

Interarch distance is a target restorative space value: clinical decisionmaking of implant restoration guided by measured value / 华西口腔医学杂志

When design an implant restoration for edentulous patients, many doctors ignore the sufficiency of the interarch distance (vertical distance) or horizontal distance of the patient to accommodate the superstructure and restoration before designing the implant plan. However, the connotation of measuring the interarch distance or horizontal distance has not been clarified in clinical practice. It is often based on visual estimation after operation, and the decision-making path of implant restoration is inverted, resulting in many mistakes regarding the restoration after implantation. The main reason is the lack of standardized paths and practical methods to use before surgery. This article recommended initially establishing a maxillo-mandibular relationship based on natural teeth, old dentures, or new ones and then using the height and horizontal distance or angle of the target restorative space, which was easier to grasp as the measured index. The minimum vertical distance (including the height of the gingival surface and the bone surface) and the horizontal distance (or the angle from the bone or gingival surface to the proposed occlusal plane) should be measured before operation. A decision tree of edentulous jaw restoration guided by the values of the repair space was established based on the measured values. This article clarified the measuring points and planes and thus provided a quantitative relationship basis for the design of implant restoration.

A novel stem cell therapy for hepatitis B virus-related acute-on-chronic liver failure

The aim of this study was to propose a stem cell therapy for hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) based on plasma exchange (PE) for peripheral blood stem cell (PBSC) collection and examine its safety and efficacy. Sixty patients (n=20 in each group) were randomized to PE (PE alone), granulocyte colony-stimulating factor (G-CSF) (PE after G-CSF treatment), and PBSC transplantation (PBSCT) (G-CSF, PE, PBSC collection and hepatic artery injection) groups. Patients were followed-up for 24 weeks. Liver function and adverse events were recorded. Survival analysis was performed. PBSCT improved blood ammonia levels at 1 week (P<0.05). The level of total bilirubin, international normalized ratio, and creatinine showed significant differences in the 4th week of treatment (P<0.05). The survival rates of the PE, G-CSF, and PBSCT groups were 50, 65, and 85% at 90 days (P=0.034). There was a significant difference in 90-day survival between the PE and PBSCT groups (P=0.021). The preliminary results suggested that PBSCT was safe, with a possibility of improved 90-day survival in patients with HBV-ACLF.
