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".

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.

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 investigate the safety and efficiency of large-dose alcohol sclerotherapy in treating simple hepatic cyst. Methods Patients with hepatic cyst were divided into two groups. One group with 49 patients was treated with small-dose (<80 ml) absolute alcohol instillation. The other one with 32 patients was treated with large-dose (≥80 ml) absolute alcohol instillation. Blood alcohol concentration (BAC) was recorded right after and 30 rain, 1 h,2 h,3 h after the treatment. Diameter of cyst as a parameter of efficiency was recorded and compared between two groups during 1 year follow-up visit. Results Large-dose group was significantly more efficient in treating hepatic cyst than small-dose group. All BAC records were within the safe range and below the legal limit after drinking. BAC reached its peak 30 minutes after the treatment began and then decreased gradually. A significant correlation was found between BAC and the alcohol dosage. Conclusions Ultrasound-guided sclerotherapy with repeated large-dose absolute alcohol instillation is a safe and efficient treatment for simple hepatic cyst from the perspective of BAC.

Objective To establish whether Wnt-signaling pathway plays a role in mice β-cell function and/or survival in vitro. Methods Mice NIT-1 beta cells were cultured in media with glucose concentration of 33.3 mmol/L and the cytokines interleukin-1β, interferon-γand tumor necrosis factor-α with or without the addition of purified Wnt3a protein in vitro. Subsequently, β-cell apoptosis by Tunnel and flow cytometry, and β-cell proliferation by BrdU were analyzed. Total RNA was extracted to measure gene expressions by real-time PCR.Results Incubations of NIT-1 cells with high glucose and cytokines resulted in an increase in β-cell apoptosis and decrease in β-cell proliferation (P<0.01). In contrast, treatment with Wnt3a protein protected β-cell from glucose and cytokines-induced apoptosis through up-regulating the expressions of above Pitx2、 TCF7L2. Conclusions Wnt-signaling regulates the proliferation of pancreatic β-cell, and protectes β-cell from glucotoxicity and cytokine toxicity with respect to proliferation and apoptosis.
