This paper reported 3 cases of poisoning caused by chlorfenagyr. Chlorfenapyr poisoning has gradually increased in clinical practice. The early stage after poisoning is digestive tract symptoms, followed by sweating, high fever, changes in consciousness, changes in myocardial enzymology, etc. Its main mechanism of intoxication is uncoupling oxidative phosphorylation. Since there is no specific antidote after poisoning, the fatality rate of chlorfenapyr poisoning remains high. The therapeutic measures are early gastrointestinal decontamination, symptomatic and supportive treatments, and early blood purification may be an effective treatment.

Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.

Aim To investigate the anti-tumor effect of celastrol(CEL)on colorectal cancer and the possible targets/mechanisms. Methods The cytotoxic activities of CEL were evaluated against A549, HCT-116, HepG2 by CCK-8 method. Western blotting was used to detect the expression level of STAT3 and its upstream and downstream proteins(JAK2, Survivin, MCL-1)in HCT-116 cells before and after CEL treatment Flow cytometry was applied to assess CEL's apoptosis and cell-cycle arrest effect in HCT-116 cells. SPR detection and molecular docking analysis were performed to further assess the binding ability between CEL and STAT3 protein. Lastly, human colorectal cancer organoid culture was constructed to verify the anti-tumor effect of CEL. Results CEL showed significant cytotoxicity to A549(IC50 = 2.37±0.02 μmol·L-1), HCT-116(IC50 = 1.40±0.21 μmol·L-1)and HepG2(IC50 = 2.52±0.02 μmol·L-1). Additionally, CEL could effectively decrease the level of p-STAT3 and the downstream gene expression of STAT3(Survivin and MCL-1)in a concentration-dependent manner; however, CEL did not affect the total level of STAT3 and upstream kinases JAK2. Moreover, CEL could induce apoptosis of HCT-116 cells concentration-dependently and arrest the cell cycle. According to the SPR analysis, CEL showed a strong binding affinity with the KD value(the equilibrium dissociation constant)of 60.38 μmol·L-1. Molecular docking analysis also suggested that CEL bound to the SH2 domain of STAT3. Lastly, CEL showed much better activity than the positive drug oxaliplatin(L-OHP)on all the colorectal cancer organoids. Conclusions CEL shows a significant anti-colorectal cancer effect, potentially caused by a direct target inhibiting STAT3, inducing apoptosis, and blocking the cell cycle.

In order to evaluate the composition and distribution characteristics of inorganic elements in Laminaria japonica, this study employed inductively coupled plasma mass spectrometry(ICP-MS) to detect the inorganic elements and used high performance liquid chromatography tandem ICP-MS(HPLC-ICP-MS) to determine the content of different arsenic species in L. japonica from diffe-rent origins. Micro X-ray fluorescence(Micro-XRF) was used to determine micro-area distribution of inorganic elements in L. japonica. The results showed that the average content of Mn, Fe, Sr, and Al was high, and that of As and Cr exceeded the limits of the national food safety standard. According to the results of HPLC-ICP-MS, arsenobetaine(AsB) was the main species of As contained in L. japonica. The more toxic inorganic arsenic accounts for a small proportion, whereas its content was 1-4 times of the limit in the national food safety standard. The results of Micro-XRF showed that As, Pb, Fe, Cu, Mn, and Ni were mainly distributed on the surface of L. japonica. Among them, As and Pb had a clear tendency to diffuse from the surface to the inside. The results of the study can provide a basis for the processing as well as the medicinal and edible safety evaluation of L. japonica.

OBJECTIVE:
To observe the effect of electroacupuncture (EA) at back-shu points of five zang on fatigue status, quality of life and motor cortical excitability in patients with chronic fatigue syndrome (CFS), so as to explore the possible mechanism of EA for CFS.
METHODS:
A total of 72 patients with CFS were randomized into an EA group (36 cases, 4 cases dropped off) and a sham EA group (36 cases, 3 cases dropped off). In the EA group, EA at Ganshu (BL 18), Xinshu (BL 15), Pishu (BL 20), Feishu (BL 13) and Shenshu (BL 23) was adopted, with continuous wave, 2 Hz in frequency. In the sham EA group, sham EA at non-acupoints (1.5-2.0 cm lateral to back-shu points of five zang) was applied, with shallow needling, and no current was connected. The treatment in the both groups was 20 min each time, once every other day, 2 weeks as one course, 3 courses were required. Before and after treatment, the scores of fatigue scale-14 (FS-14) and the MOS 36-item short form health survey (SF-36) were observed, and cortical excitability (the resting motor threshold [RMT], amplitude of motor-evoked potential [MEP-A] and latency of motor-evoked potential [MEP-L]) was detected in the two groups.
RESULTS:
After treatment, the physical fatigue score, mental fatigue score and total score of FS-14, as well as RMT of motor cortex in the EA group were decreased compared with those before treatment (P<0.01), the physical fatigue score and total score of FS-14 in the sham EA group were decreased compared with those before treatment (P<0.05); each item score and total score of FS-14 and RMT of motor cortex in the EA group were lower than those in the sham EA group (P<0.01, P<0.05). After treatment, each item score and total score of SF-36 and MEP-A of motor cortex in the EA group were increased compared with those before treatment (P<0.01), which were higher than those in the sham EA group (P<0.01, P<0.05).
CONCLUSION
EA at back-shu points of five zang can effectively improve the fatigue status and quality of life in patients with CFS, its mechanism may be related to the up-regulating excitability of cerebral motor cortex.

Patrinia villosa, regarding its functions in clearing heat and detoxification and eliminating carbuncles and pus, is widely used as a traditional medicinal herb that contains rich nutrition and substances such as various amino acids, vitamins, and soluble su-gar, and it is also an edible wild herb in Chinese folk tradition for 2 000 years. In 1973, Japanese scholars firstly separated three iridoids from Japanese P. villosa, and by 2021, chemical components such as flavonoids, iridoids, organic acids, triterpenoids, phenylpropanoids, and steroids have been found, which have multiple pharmacological effects, including antioxidant, antitumor, anti-diarrhea, antibacterial, sedative, and liver protection capabilities. Studies indicate that flavonoids, saponins, phenylpropanoids, and triterpenoids in P. villosa are vital substances for its pharmacological activities. However, the quality of this medicinal material cannot be controlled due to the unclear records in ancient books in the past dynasties and different drug use habits in different places, and thus its circulation is chaotic. At present, researchers have used flavonoids, organic acids, phenylpropanoids, triterpenoid saponins, and other compounds to conduct studies in this regard. Therefore, on the basis of the existing literature resources, we comprehensively summarize the chemical constituents, pharmacological activities, and quality control of P. villosa to further provide a reference for the safety and effectiveness of clinical drug use and lay a foundation for the follow-up experimental research.

Imported medicinal materials are an important part of Chinese medicinal resources. To be specific, about 10% of the around 600 commonly used Chinese medicinal materials are from abroad, and the introduction of foreign medicinal materials has promoted the development of Chinese medicine. Amid the advancement of reform and opening up and the "Belt and Road" Initiative, major headway has been made in the cross-border trade in China, bringing opportunities for the import of medicinal materials from border ports. However, for a long time, there is a lack of systematic investigation on the types of exotic medicinal materials at border ports. In the fourth national census of traditional Chinese medicine resources, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences, together with several organizations, investigated the nearly 40 border ports, Chinese medicinal material markets, and border trade markets in 6 provinces/autonomous regions in China for the first time and recorded the types, sources, circulation, and the transaction characteristics of imported medicinal materials. Moreover, they invited experts to identify the origins of the collected 237 medicinal materials. In addition, the status quo and the problems of the medicinal materials were summarized. This study is expected to lay a basis for clarifying the market and origins of imported medicinal materials as well as the scientific research on and supervision of them.

OBJECTIVES:
To investigate the effect of sequential sedative and analgesic drugs in preventing delirium and withdrawal symptoms in children after ventilator weaning.
METHODS:
A retrospective analysis was performed on 61 children who were admitted and received mechanical ventilation support for ≥5 days in the Pediatric Intensive Care Unit of Dongguan Children's Hospital Affiliated to Guangdong Medical University from December 2019 to September 2021. The children were divided into a control group (30 children with no maintenance of analgesic and sedative drugs after ventilator weaning) and an observation group (31 children with sequential sedative and analgesic drugs maintained for 48 hours after ventilator weaning). The two groups were compared in terms of the Sophia Observation Withdrawal Symptoms Scale (SOS) score, the Pediatric Delirium Scale (PD) score, the Richmond Agitation-Sedation Scale (RASS) score, and the incidence rates of delirium or withdrawal symptoms at 24 and 72 hours after ventilator weaning.
RESULTS:
There was no significant difference in the incidence rate of delirium at 24 hours and 72 hours after ventilator weaning between the two groups (P>0.05). Compared with the control group, the observation group had significantly lower incidence rate of withdrawal symptoms and scores of SOS, PD, and RASS scales at 24 hours and 72 hours after ventilator weaning (P<0.01).
CONCLUSIONS
Sequential sedation and analgesia after ventilator weaning can reduce the incidence of withdrawal symptoms within 72 hours after ventilator weaning, but it cannot reduce the incidence rate of delirium.

In order to provide the basis for the development of famous classical formulas containing Myrrha, the name, origin, quality evaluation, harvest and processing of Myrrha were systematically researched by consulting the ancient herbal and medical books, combining with the modern related literature. According to textual research, the results showed that Commiphora myrrha was the main base in ancient times, which was produced in Somalia, Ethiopia and northern Kenya. In addition, raw and fried products of Myrrha were the commonly used specifications in ancient herbal medicine, which are still used today. Nowadays, Myrrha, fried Myrrha and vinegar-processed Myrrha were the commonly used specifications. Among the three specifications, Myrrha is the raw products after cleaning, fried Myrrha is a kind of processed products, which has relevant records in ancient materia medica and is still used today. Vinegar-processed Myrrha is a new processing specification in modern times. Based on the research results, it is suggested that Myrrha in Shentong Zhuyutang should be the purified raw Myrrha in accordance with the 2020 edition of Chinese Pharmacopoeia.
