ABSTRACT
Osteoporosis （OP）， a common systemic skeletal disease in the elderly， is characterised by bone loss and bone microstructural degeneration. Its clinical manifestations include increased bone fragility and bone pain. Furthermore， OP increases the risk of fracture due to the high bone fragility， which leads to lifelong disability or death， imposing a heavy economic and psychological burden on the patients and their families. The pathogenesis of OP is extremely complex and associated with a variety of factors such as proliferation and differentiation of osteoblasts， impairment of osteoclast activity and function， and abnormalities in autophagy activation. Recent studies have found that mammalian target of rapamycin （mTOR） signaing pathway is involved in the regulation of bone homeostasis， which can promote bone formation and improve bone metabolism and bone microstructure by regulating osteoblast proliferation and differentiation and osteoclast function and activating cellular autophagy， thus playing a crucial role in the prevention and treatment of OP. The prevention and treatment of OP with Chinese medicine has a long history， clear efficacy， multiple targets of action， low adverse effects， and wide medicine sources. Therefore， this paper briefly describes the role of mTOR signaling pathway in the development of OP by reviewing the latest research reports and summarizes in detail the latest research results on the treatment of OP with Chinese medicine extracts and prescriptions via the mTOR signaling pathway. This review aims to provide a basis for the in-depth research on the relationship between mTOR signaling pathway and OP and the clinical application of traditional Chinese medicine in the prevention and treatment of OP.
ABSTRACT
In order to explore the effect of extract (SNE) on skin wound healing in mice and its mechanism, hemostasis effect of SNE was measured, the mouse skin wound model was established by full-thickness excision. The morphological changes of the wound were observed after the treatment with SNE and the healing rate was measured. The changes of wound histology were observed by hematoxylin eosin (HE) staining, Masson staining and transmission electron microscope (TEM). The expression of cell factors and related proteins was detected by quantitative real-time polymerase chain reaction (qRT-PCR). Results showed that the SNE possessed hemostatic function. SNE could obviously improve the healing rate of wound in mouse and shorten time of scab removal compared with the none-treatment (NT) group ( 0.05). These results indicated that SNE possessed obvious activity of accelerating wound healing and inhibiting scar formation, and its mechanism was closely related to hemostatic function, regulation of inflammatory factors, collagen deposition, collagen fiber remodeling and intervening TGF-β/Smads signal pathway. Therefore, SNE may have promising clinical applications in skin wound repair and scar inhibition.
ABSTRACT
Objective To observe the effect of Yunnanbaiyao combined with gelatin sponge on wound healing in patients with post-extraction hemorrhage.Methods 72 patients received dental extraction were selected,and they were divided into observation group (Yunnanbaiyao + gelatin sponge) and control group (gelatin) according to the digital table,each group in 36cases.The hemostasis after treatment and the improvement of pain after 12h and 24h after treatment were observed.The wound healing was observed in the two groups after 7 days of treatment.Results After treatment,the total effective rate was 91.67％ in the observation group and 69.44％ in the control group.The effective rate of hemostasis in the observation group was significantly higher than that of the control group(x2 =7.32,P =0.007).The VAS scores of the observation group at 12 h (t =23.44,P =0.000) and 24h (t =22.86,P =0.000) after pack treatment obviously decreased;The VAS scores of the control group at 12h(t =19.87,P =0.000) and 24h (t =18.47,P =0.000) after pack treatment obviously decreased;The VAS scores of the observation group at 12h and 24h after pack treatment was lower than those of the control group,the differences were statistically significant(t =7.03,5.03,all P =0.000).The wound healing of the observation group was improved after 7d treatment(t =8.12,P =0.00);The wound healing of the control group was improved after 7d treatment(t =5.39,P =0.00);The wound healing of the observation group was better than that of the control group,the differences were statistically significant (t =2.88,P =0.005).Conclusion Yunnanbaiyao combined with gelatin sponge can relieve the bleeding symptoms after tooth extraction,promote wound healing,reduce the patients' pain.
ABSTRACT
Objective To analyze the clinical characteristics of epileptic children at early stage,and to explore the high risk factors for children′s refractory epilepsy(RE)in order to provide evidence for the early and timely treatment of RE.Methods A total of 147 epileptic patients with correct diagnosis and reasonable treatment were enrolled.Forty-nine patients were classified as drug non-responsive epilepsy(DNR-EP group).The remaining 98 patients were classified as drug-responsive epilepsy(DR-EP group).With multiple conditional Logistic regression,the clinical characte-ristics between the 2 groups were compared to identify the early predictors for RE.Results Single factor Logistic regression analysis showed that the initial age of onset <1 year,more than 20 seizures before treatment in a week,focal seizures,more than 2 kinds of epileptic seizures,changes in seizure type in the course of disease,neurological impairment,early intellectual disability,abnormal cranial magnetic resonance imaging(MRI),fixed focal abnormalities on video electroencephalogram(VEEG) after seizure-free interval,diffused anomaly of non-epileptic wave in VEEG before treatment,poor response to initial antiepileptic drugs(AEDs) therapy,compliance with the characteristics of epileptic encephalopathy at early stage significantly increased in DNR-EP group.Then multivariate conditional Logistic regression analysis demonstrated that more than 20 seizures before treatment in a week(OR=2.679,P=0.043),more than 2 kinds of epileptic seizures(OR=4.364,P=0.013),fixed focal abnormalities on VEEG after seizure-free interval(OR=3.898,P=0.008),poor response to initial AEDs therapy(OR=2.611,P=0.036),and compliance with the characteristics of epileptic encephalopathy at early stage(OR=6.022,P=0.002) were the risk factors for developing into RE.Conclusions Children are likely to develop into RE if they have more than 20 seizures before treatment in a week,with more than 2 kinds of epileptic seizures,fixed focal abnormalities on VEEG after seizure-free intervals,poor response to initial AEDs therapy,and compliance with the characteristics of epileptic encephalopathy at early stage.
ABSTRACT
OBJECTIVE:To investigate the effects of Kouyanqing granules on prevention and treatment of radiation-induced oral mucositis patients with head and neck cancer after radiotherapy.METHODS:A total of 122 head and neck cancer patients receiving radiotherapy were randomly divided into kouyanqing group (61 cases) and chlorhexidine group (61 cases).Based on radiotherapy,kouyanqing group was given Kouyanqing granules 20 g dissolved in 50 mL lukewarm boiled water,twice a day,2-3 d before radiotherapy.Chlorhexidine group was given Compound chlorhexidine gargle 10-20 mL,twice a day,2-3 d before radiotherapy.Treatment courses of 2 groups lasted for 7 weeks.The occurrence of oral mucositis,VAS scores and ADR were observed in 2 groups.RESULTS:3rd week radiotherapy later,the incidence of oral mucositis at level 2-3 and 4th-7th week radiotherapy later,the incidence of oral mucositis at level 2-4 in kouyanqing group was significantly lower than chlorhexidine group,with statistical significance (P＜0.01).2nd-7th week radiotherapy later,VAS score of kouyanqing group was significantly lower than that of chlorhexidine group,with statistical significance (P＜0.01).There was no statistical significance in the incidence of ADR between 2 groups (P＞0.05).CONCLUSIONS:Kouyanqing granules can relieve radiation-induced oral mucositis of head and neck cancer and the degree of pain,and improve the quality of life.Its safety is similar to that of chlorhexidine.
