1. New progress in pharmacological action of paeoniflorin
Chinese Traditional and Herbal Drugs 2019;50(15):3735-3740
Paeoniflorin is the main effective component of Paeoniae lactiflora and Paeonia suffruticosa. A large number of studies have proven that paeoniflorin has many pharmacological effects, such as anti-depression, anti-inflammation, analgesia, anti-tumor, liver protection, nerve protection, sedation and hypnosis, immunomodulation and so on. It has little toxic and side effects and has been highly concerned by people. At present, paeoniflorin is rarely used in clinical practice in the form of monomers. This article mainly refers to the related research literatures on paeoniflorin pharmacological action in recent three years, combs and summarizes the new progress of its pharmacological action research. The relationship between the drug effect and the prescription of traditional Chinese medicine was discussed, in order to provide a reference for further development and clinical application of paeoniflorin.
2. Research progress on sedative and hypnotic effect of Sini Powder and strategic analysis of its new drug development
Chinese Traditional and Herbal Drugs 2020;51(13):3575-3584
Sini Powder is the traditional Chinese medicine compound, which comes from Treatise on Febrile Diseases. It is used to treat the syndrome of yang depression and reversal cold of limbs. Sini Powder has a certain effect on treating insomnia caused by liver depression and spleen deficiency. Lots of researches have shown that Sini Powder has a sedative and hypnotic effect similar to diazepam and plays an important role in improving sleep disorders caused by post-traumatic stress disorder (PTSD). Sini Powder is not included in Chinese Pharmacopoeia (2015 edition). It is probably to develop Sini Powder into a new drug for the clinic. We collated and summarized the literature about the sedative and hypnotic effect and the improvement of sleep disorders caused by PTSD of Sini Powder. Based on the modern research on the sedative and hypnotic effect of Sini Powder, we think the effect of "relieve uneasiness of mind and body tranquilization" adapts the theory of traditional Chinese medicine, so that it can improve the applied range of Sini Powder. Meanwhile, we analyzed the possibility of Sini Powder being selected into the ancient classical prescription and key problem in research and development on drug preparation of Sini Powder according to regulations of traditional Chinese medicine. Then we put forward some suggestions for further research from two aspects which are the development of Sini Powder and new drugs of traditional Chinese medicine, to provide a reference for the development of new Chinese medicine preparation of Sini Powder focus on "expelling pathogen and relieving depression, soothing liver and regulating spleen, tranquilizing mind".

OBJECTIVETo observe the effects of electroacupuncture (EA) at "Dazhui" (GV 14) on Wnt-β-catenin signal pathway in annulus fibrosus cells in intervertebral disc in rats with cervical spondylosis.
METHODSForty SD rats were randomized into a control group, a model group, an EA group and a medication group, 10 rats in each one. Rats in the control group were treated with sham operation, only incision on local skin; rats in the remaining groups were made into cervical spondylosis models. After model establishment, rats in the control group and model group received fixed treatment under identical condition; rats in the EA group were treated with EA at "Dazhui" (GV 14), 30 min per treatment; rats in the medication group were treated with intragastric administration of meloxicam tablets. Treatments were both given once a day, and 14 days were taken as one session; there was an interval of 2 days between two sessions, and totally two sessions were given. After the treatments, immunohistochemistry was applied to measure the expression of Wnt, glycogen synthase kinase-3β (GSK-3β) and Axin in annulus fibrosus cells; western blot was used to test the expression of P-β-catenin.
RESULTSIn the control group, there were more positive cells of Wnt, GSK-3β and Axin, which were intensively distributed, deeply colored, and strongly positive; In the model group, there were less positive cells of Wnt, GSK-3β and Axin, which were sparsely distributed and weakly positive. The expression of Wnt, GSK-3β, Axin and P-β-catenin in the model group was less than that in the control group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin in the EA group and medication group was higher than that in the model group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin was not significantly different between EA group and medication group (all P > 0.05).
CONCLUSIONEA could delay the degeneration of intervertebral disc, which may be related to EA inhibiting signal pathway of Wnt-β-catenin.

Objective To evaluate the long-term clinical efficacy and security of levetiracetam (Lev) as add-on therapy in patients with different types of epilepsies from an observational study.Methods Fifty-one patients were evaluated (14 female,37male,age range from 7months to 16 years,mean age 8.7 years) with different types of epilepsies ( 20 complex partial seizure,10 tonic-clonic seizure,1 tonic seizure,6 myoclonic epilepsy,2 Lennox-Gastaut syndrome,4 infantile spasms and 2 unspecified epileptic syndromes).The basis for comparison was defined as the seizure frequency in the 3 months prior to the commencement of treatment.Patients received Lev as add-on therapy.The initial dosage was 20 mg/(kg?d),and it was increased 10 mg/(kg?d) every 2 weeks.The maintenance dosage was 30-40 mg/(kg?d).Seizure frequency changes and adverse events were observed.Follow-up was conducted for a period of 6.8 months after treatment.SPSS 14.0 software was used to compare the difference between the seizure frequency before the Lev treatment and that after the Lev treatment.Results Thirteen (25.5%) out of the 51 patients reduced seizure frequency,16 (31.4%) patients had no reoccurrence;While another 9 (17.6%) patients seizure frequencied were reduced,8 patients' remained the same,and 5 patients' condition was got wor-sened.Six cases ceased treatment because of the worsening of the disease and the intolerance of Lev.The difference and after seizure frequency before in Lev treatment is statistically significant(P
