Objective:To observe the clinical effect of acupuncture treatment based on Tiaoshen theory for the patients with functional dyspepsia (FD) and depression with liver-stomach disharmony syndrome. Methods:A total of 76 FD patients from May 2018 to August 2019 were randomly divided into 2 groups with 38 patients in each group. In the routine group, acupoints were selected routinely, and in Tiaoshen group, acupoints were selected by Tiaoshen theory. Both groups were treated for 28 days. The results were evaluated by Nepean Dyspepsia Index (NDI), TCM Syndrome Score and Hamilton Depression Scale-24 (HAMD-24). Results:The total effective rate of both groups was 94.6% (35/37) in Tiaoshen group and 75.0% (27/36) in routine group. There was significant difference between the two groups ( χ2=6.125, P=0.011). The NDI in Tiaoshen group was significantly lower than that of routine group ( t=3.038, P=0.003). The scores of interference domain, control domain, food and beverage domain and sleep disturbance domain in Tiaoshen group were significantly higher than those in routine group ( t=3.096, 2.460, 2.225, 2.732, P<0.05); the TCM Syndrome Score in Tiaoshen group was significantly lower than that of routine group ( t=3.241, P=0.002), and that of HAMD-24 was significantly lower than that of routine group ( t=2.767, P=0.007). Conclusion:Treatment based on Tiaoshen theory can improve the quality of life of FD patients in the fields of interference, control, food and beverage and sleep disturbance, and reduce the patients’depression.

ObjectiveTo explore the possible mechanism of Yudian Decoction （愈癫汤） in the treatment of schizophrenia. MethodTwenty male offspring from 5 normal female 17-day-pregnant SD rats were selected as blank group. Fifteen female 17-day-pregnant SD rats were injected intraperitoneally with methyl azomethine acetate （MAM） 25 mg/kg， and the male offspring simulated the neurodevelopmental abnormality to establish a rat model of schizophrenia. Sixty successfully-modeled rats were randomly divided into 20 rats in the model group， 20 rats in the Yudian Decoction group and 20 risperidone group. After 3 days of adaptive cage feeding， the rats in the Yudian Decoction group were gavaged with 1.54 g/（kg·d） of Yudian Decoction， the risperidone group was gavaged with 0.24 mg/（kg·d） of risperidone capsule， while the blank group and the model group were gavaged with 6.7 ml/（kg·d） of distilled water， once a day， for 14 consecutive days. Sample was collected on the day after the last gavage. The expression of glutamate receptor （GluR） and γ-aminobutyric acid receptor subunit α1 （GABAARα1）-positive neurons in the hippocampus and prefrontal cortex were detected by immunofluorescence， and the positive rate was calculated； the expression of small clear proteins （PVs） in the hippocampal CA1 region and the medial prefrontal cortex was detected by immunohistochemistry； The expression of glutamic acid decarboxylase 65 （GAD65） and glutamic acid decarboxylase 67 （GAD67） proteins and mRNAs in the hippocampus and prefrontal cortex were detected by immunoblotting and reverse transcription PCR. ResultCompared with the blank group， the positive rate of GluR in hippocampal area and prefrontal cortex of rats in the model group increased， the positive rate of GABAARα1 in hippocampal area decreased， the PV optical density value in hippocampal CA1 area and medial prefrontal cortex decreased， and the expression of GAD65， GAD67 proteins and mRNA in hippocampal area and prefrontal cortex decreased （P＜0.05 or P＜0.01）. Compared with the model group， GluR positivity rate in hippocampus and prefrontal cortex of risperidone group and Yudian Decoction decreased， GABAARα1 positivity rate in hippocampus increased， PV optical density value in hippocampus CA1 area and medial prefrontal cortex increased， and GAD65， GAD67 proteins and mRNA expression in hippocampus and prefrontal cortex increased （P＜0.05 or P＜0.01）. Compared with the risperidone group， the positive rate of GluR in hippocampus and prefrontal cortex and GABAARα1 in hippocampus in the Yudian Decoction group was reduced， the PV optical density value of hippocampal CA1 area was increased， the protein and mRNA expression of GAD67 in hippocampus area was elevated， and the protein expression of GAD65 in prefrontal cortex was reduced （P＜0.05）. ConclusionYudian Decoction may improve the pathological process of schizophrenia by regulating key regulators of glutamate/γ-aminobutyric acid （Glu/GABA） metabolic balance in the hippocampus and prefrontal cortex and maintaining the balance between neuronal excitation and inhibition.

As one of the most difficult-to-cure neuropsychiatric disorders in clinical practice， schizophrenia is mainly manifested by behavioral abnormalities and multidimensional cognitive dysfunction， and the recurrence rate and disability rate of the disease are increasing year by year， which seriously affects patients' social functioning and quality of life， and even threatens the physical and mental health of the surrounding population. At present， the treatment of schizophrenia is mainly based on antipsychotic drugs combined with psychotherapeutic techniques， which have limited long-term therapeutic effects and a high relapse rate. Traditional Chinese medicine （TCM） boasts the advantages of multi-targets， multi-pathways， multi-links， and multi-levels， and plays a crucial role in the prevention and treatment of schizophrenia and its prognosis. Phosphatidylinositol 3-kinase （PI3K） is widely present in cells and is involved in the regulation of protein synthesis and apoptosis， and the different isoforms of protein kinase B （Akt） are of great significance in cell growth， oxidative stress， neuronal development and other processes. In recent years， a large number of studies have found that the PI3K/Akt signaling pathway is closely related to schizophrenia. Through regulating the PI3K/Akt signaling pathway， TCM monomers and TCM compounds mainly affect key signaling molecules such as mammalian target of rapamycin （mTOR）， glycogen synthase kinase （GSK）， glucose transporter （GLUT） for glucose uptake and transport， and nuclear factor E₂-associated factor 2 （Nrf2）， which organize the intracellular network of centers and regulate the formation and plasticity of neuronal synapse， and they play an important role in mitigating schizophrenia by regulating the processes of cell proliferation， migration and apoptosis of neurons， and has the advantages of multi-targets， all-encompassing and low toxicity. This article analyzes and explains the mechanism of TCM intervention in the PI3K/Akt signaling pathway against schizophrenia， in order to provide a theoretical basis and reference for the prevention and treatment of schizophrenia by TCM.

Schizophrenia has various obstacles in cognition， thinking， emotion， behavior and other aspects； it belongs to the category of “madness” in traditional Chinese medicine （TCM）. Once schizophrenia occurs， multiple factors are often intertwined， and a single therapy is difficult to be effective. At present， TCM compounds and active ingredients have significant effects in the clinical treatment of schizophrenia， which is an important direction for the development of new drugs for schizophrenia. This article summarizes the molecular mechanism of TCM compounds and active ingredients in the treatment of schizophrenia. It is found that Wendan decoction and Yudian decoction can inhibit the apoptosis of hippocampal cells by activating BDNF/TrKB/CREB signaling pathway； quercetin and icariin can promote neural development and regeneration by activating NMDA/ERK signaling pathway； Wendan decoction and icariin can maintain neural cell homeostasis by activating PI3K/AKT signaling pathway； Bushen zhuangyang capsule can enhance learning and memory abilities by activating CaMKⅡ signaling pathway； formulas such as Huatan huoxue tongzhi formula can enhance intercellular information transmission by inhibiting PKC signaling pathway； α-humulene and others can restore nerve cell function by inhibiting NRG1/ErbB4 signaling pathway. TCM compounds and active ingredients can improve schizophrenia by intervening in the above-mentioned signaling pathways.
