A digital intervention using virtual reality helmets to reduce dental anxiety of children under local anesthesia and primary teeth extraction: A randomized clinical trial.

INTRODUCTION: Behavior management of children during dental treatment is an important but challenging issue. As a new technique, VR has been applied in pediatric dental anxiety. But there is no final conclusion whether VR reduces children's dental anxiety. METHODS: The aim of the study is to assess the effectiveness of a digital intervention using virtual reality (VR) helmets on dental anxiety, pain perception, and behavior triggered for children, as well as occurrence of simulator sickness in local anesthesia and primary teeth extraction. A total of 128 children, who needed primary teeth extraction under local anesthesia, were randomly allocated into two groups: use VR helmets and traditional behavior guidance procedures (control). Modified Child Fear Survey Schedule Dental Subscale (CFSS-DS), Wong-Baker FACES Pain Scale, Houpt Scale, and Simulator sickness questionnaire (SSQ) were used to assess children's dental anxiety, pain perception, and behavior triggered and occurrence of simulator sickness. RESULTS: CFSS-DS score in the VR group was significantly decreased after dental treatment (34.58±6.90 before operation and 32.32±15.58 after operation, p = .02). The score of Wong Baker Scale in the VR group (3.47±0.76) was significantly lower than that in the control group (5.56±1.13, p = .015). There was no significant difference in the Houpt Behavior Scale score and the SSQ score between the VR group and the control group (p = .35, p = .305). CONCLUSION: The use of VR helmets in primary teeth extraction can significantly reduce dental anxiety and pain perception in children without occurrence of simulator sickness.

Anti-tumor Effect and Mechanisms of Triterpenoids and Polysaccharides in Ganoderma lucidum： A Review / 中国实验方剂学杂志

With the population aging， the morbidity and mortality of cancer patients continue to rise. At present， the treatment methods for tumors include surgery， chemotherapy， radiotherapy， targeted therapy， and immunotherapy. However， most chemotherapeutic drugs can cause severe side effects and drug resistance. Therefore， as an alternative therapy， traditional Chinese medicine （TCM） treatment can effectively relieve the clinical symptoms of tumor patients， improve the quality of life， inhibit or stabilize the development of tumors， and prolong the survival period of patients. Due to the good safety of Chinese medicine， its potential anti-cancer activity has attracted increasing attention. Ganoderma lucidum， a treasure of Chinese medicinal material， is a medicinal fungus with a history of more than 2 000 years in China. So far， many studies have proposed the anti-cancer properties of G. lucidum. G. lucidum has extensive pharmacological activities， such as anti-tumor， anti-atherosclerosis， and anti-aging. It can also regulate immunity， protect the liver and the heart， and reduce blood glucose and lipid. The chemical composition of G. lucidum is complex. At present， it is proved to contain polysaccharides， triterpenoids， alkaloids， nucleosides， amino acids， and various trace elements. The anti-tumor mechanisms of polysaccharides and triterpenoids in G. lucidum are mainly achieved by apoptosis induction， immune regulation， anti-angiogenesis， and induction of cell cycle arrest. Currently， it has been widely used in the adjuvant treatment of complex tumors such as lung cancer， liver cancer， cervical cancer， prostate cancer， breast cancer， and colon cancer. The present study reviewed the bioactivities and mechanisms of triterpenoids and polysaccharides in G. lucidum in recent years and highlighted the anti-tumor effects and mechanisms to provide references for the further development and utilization of G. lucidum.

Co-Delivery of Curcumin and Paclitaxel by "Core-Shell" Targeting Amphiphilic Copolymer to Reverse Resistance in the Treatment of Ovarian Cancer.

BACKGROUND: Ovarian cancer is a common malignancy in the female reproductive system with a high mortality rate. The most important reason is multidrug resistance (MDR) of cancer chemotherapy. To reduce side effects, reverse resistance and improve efficacy for the treatment of ovarian cancer, a "core-shell" polymeric nanoparticle-mediated curcumin and paclitaxel co-delivery platform was designed. METHODS: Nuclear magnetic resonance confirmed the successful grafting of polyethylenimine (PEI) and stearic acid (SA) (PEI-SA), which is designed as a mother core for transport carrier. Then, PEI-SA was modified with hyaluronic acid (HA) and physicochemical properties were examined. To understand the regulatory mechanism of resistance and measure the anti-tumor efficacy of the treatments, cytotoxicity assay, cellular uptake, P-glycoprotein (P-gp) expression and migration experiment of ovarian cancer cells were performed. In addition, adverse reactions of nanoformulation to the reproductive system were examined. RESULTS: HA-modified drug-loaded PEI-SA had a narrow size of about 189 nm in diameters, and the particle size was suitable for endocytosis. The nanocarrier could target specifically to CD44 receptor on the ovarian cancer cell membrane. Co-delivery of curcumin and paclitaxel by the nanocarriers exerts synergistic anti-ovarian cancer effects on chemosensitive human ovarian cancer cells (SKOV3) and multi-drug resistant variant (SKOV3-TR30) in vitro, and it also shows a good anti-tumor effect in ovarian tumor-bearing nude mice. The mechanism of reversing drug resistance may be that the nanoparticles inhibit the efflux of P-gp, inhibit the migration of tumor cells, and curcumin synergistically reverses the resistance of PTX to increase antitumor activity. It is worth noting that the treatment did not cause significant toxicity to the uterus and ovaries with the observation of macroscopic and microscopic. CONCLUSION: This special structure of targeting nanoparticles co-delivery with the curcumin and paclitaxel can increase the anti-tumor efficacy without increasing the adverse reactions as a promising strategy for therapy ovarian cancer.

RAM study on general standard of maximum residue limits for pollution-free traditional Chinese medicine based on Chinese Pharmacopoeia formula / 中国中药杂志

The excessive pesticide residues and heavy metals in traditional Chinese medicine seriously endanger human health and the sustainable development of Chinese medicine industry. In order to improve the quality of traditional Chinese medicine and establish a general standard for maximum residue limits(MRL) of pesticides in pollution-free traditional Chinese medicine and decoction pieces, and to ensure the safety of clinical medication from its origin, MRLs were calculated based on the formula(MRL=A×W/100M) from Chinese Pharmacopeia, comparing it with the current Chinese and international standards as well as literature review, the RAND/UCLA appropriateness method(RAM) was applied to determine the categories and MRLs of pesticides in pollution-free traditional Chinese medicine and decoction pieces. Two questionnaires were drafted for expert panel and appropriateness analysis was carried out with the 9-point Likert scale to determine the general standard for MRLs of pollution-free traditional Chinese medicine and decoction pieces. The results showed that a total of nine experts from different fields scored the necessity of standard-setting and 206 pesticide residue limits respectively. The appropriateness scores of 206 pesticides were greater than 7, and appropriateness rate was 100%, which signifies that the expert panel has reached consensus. In summary, based on the RAM, the general standard for maximum residue limits of pesticides in pollution-free Chinese medicines and decoction pieces has reached an expert consensus. Comparing with the MRLs of medicinal plants and plant-sourced food from CAC, Europe Union, the United States, South Korea, Japan, Australia, New Zealand and Canada, 206 MRLs from this general standard share 88.8% in common, 4.4% of which is higher and 6.8% lower than those international standards. This has provided a basis for standardizing the use of pesticides in pollution-free traditional Chinese medicine.

OBJECTIVE: To study the effects of musk ketone at different concentrations on in vivo migration of exogenous rat bone marrow mesenchymal stem cells (rBMSCs), thus screening out the optimal therapeutic dose. METHODS: Forty SD rats were randomly divided into 4 groups, 10 in each group. The rat model of skull defect was established using dental surgery. The primary rBMSCs were cultured by adherence screening method. The third passage cells were labeled by 10 micromol/L BrdU, and the labeled cells were injected into skull defect rats from the tail vein. Rats were administered with musk ketone at high, moderate and low concentration, respectively by gastrogavage, while equal volume of normal saline was administered to those in the blank control group by gastrogavage. Their skulls were taken out 14 days later, fixed, and decalcified. BrdU positive cells were counted under fluorescence microscope. RESULTS: After immunohistochemical processing, the gray scale analysis was preformed. There was statistical difference in the BrdU positive cell number between the blank control group and the low and moderate concentration musk ketone groups (P < 0.01). There was no statistical difference in the BrdU positive cell number between the blank control group and the high concentration musk ketone group (P > 0.05). CONCLUSION: Musk ketone could accelerate the in vivo migration of exogenous stem cells, with the optimal effects obtained at moderate and low concentrations.
