Objective To investigate the characteristics of TCM syndromes of Tourette syndrome (TS) to find out the basis for its TCM treatment. Methods Based on the preliminary studies,the TCM syndrome scale of TS is designed to investigate the general data,main symptoms and syndromes of 126 cases of TS children to find out the frequency of each syndrome. Results Of the 126 TS cases,97 were males,accounting for 77%; the average age was 8.31 years; and 32 had a positive family history,accountting for 25.4%. In the tic behavior,the facial twitching and limb twitching occupied 91.6% of the muscular stereotyped tic. In the vocal behavior,the throat and nasal sound occupied 42.1%. In the accompanied symptoms,the inattention occupied 69.8%. In the personality offset,the willfulness occupied 49.2%,irritable hyperactivity occupied 78.6%,and silence occupied 7.1%. More than 50% of the patients had red or dark red tongue with thick or sticky coating. Nearly 70% of them had string-taut or rolling pulse. As for the syndromes,heart-liver deficiency with deficiency wind stirred up,and liver-kidney yin deficiency with yang hyperactivity stirring up wind were common,being 41.3% and 34.1% respectively. Conclusion TS takes the heart-liver deficiency with deficiency wind stirred up and liver-kidney yin deficiency with yang hyperactivity stirring up wind as the common syndromes. The basic treating principle is enriching yin and reducing yang,and smoothing the liver to stop wind. At the same time,reinforcing the spleen and nourishing the heart,and dissolving phlegm and enlightening the brain should be applied for treatment.

To investigate the apoptosis-inducing effect of cinobufacini (Huachansu) on human hepatoma cell line HepG2 and its possible mechanism of action, HepG2 cells were treated with different concentrations of cinobufacini. Cell proliferation was measured by methylthiazolyl tetrazolium (MTT) assay. The morphological changes of apoptosis were observed by Hoechst 33258 staining. Cell cycle distribution and apoptotic rate were evaluated by flow cytometry (FCM). Quantitative real-time RT-PCR and Western blotting analysis were used to detect the mRNA and protein expressions of apoptosis related factors Bcl-2, Bax and p53. The results indicated that cinobufacini could inhibit the proliferation of HepG2 cells in a dose and time dependent manner. Remarkable morphological changes of apoptosis including cytoplasmic and nuclear condensation and partition of cytoplasm were observed by Hoechst 33258 staining. According to FCM analysis, HepG2 cells were arrested in G2/M phase and the apoptotic rate increased with the increase of the concentration of cinobufacini. Both the mRNA and protein expressions of Bax and p53 were up-regulated while Bcl-2 expression down-regulated. Thus, cinobufacini could inhibit the proliferation and induce apoptosis of human hepatoma cell line HepG2. Furthermore, up regulation of Bax and p53 as well as down regulation of Bcl-2 expressions may be one of the important apoptotic inducing mechanisms.

Objective To investigate the effect of Ningdong granule on 5-hydroxytryptamine metabolism and 5-HT2AR of Tourette’s Syndrome(TS) rat models. Methods 32 SD rats were divided into 4 groups randomly, the control group, the model (Apo) group, the low dosage NDG (NGL) group, and the high dosage (NGH) group. TS rat models were induced by intraperitoneal injection (i.p.) with Apo (2 mg/kg) in the experimental groups last 4 weeks. Rats in the control group were injected with normal saline (0.9%) (3 ml/kg, i.p.). Then, the rats were treated by intragastric administration (i.g.) with ND granular at 1.8g/(kg?d)in NGL group, with ND granular at 3.6 g/(kg?d)in NGH group, with distilled water at equal Volume in Control group and Apo group respectively for 12 successive weeks. Analysis the striatum 5-HT2AR protein expression by Immunohistochemical method;Determination of the content of 5-HT and 5-HIAA in striatum by Enzyme linked immunosorbent assay (ELISA). Results The level of 5-HT and 5-HT2AR protein expression in the model group [(1.98±0.14)ng/ml and(143.10±8.01)], compared with the control group[(1.78±0.10)ng/ml and(127.43±6.72)], was up-regulated (P<0.01 or 0.05). The levels of 5-HT and 5-HT2AR protein expression in NGH group[(2.20±0.14)ng/ml and(166.33±9.21)ng/ml] were further up-regulated, and the levels of 5-HIAA in NDH group [(0.58±0.08) ng/ml] became lower, compared with the control group(P<0.01 or 0.05). Conclusion Activity of 5-HT system enhanced in Apo-induced TS rat model. However, the enhanced activity may still be relatively insufficient. The mechanism of ND granulear treating TS was associated with depression of the 5-HT metabolism, up-regulation expression of 5-HT2AR, and improving the activity insufficient of 5-HT system.

In the past decade, the role of the mevalonic acid pathway and its inhibitor statins in preventing tumorigenesis and improving tumor prognosis has attracted wide attention; however, so far, there are still controversies over the role of statins in liver cancer. Previous studies have shown that statins play an important role in cholesterol metabolism, antioxidation, and anti-inflammation, and cholesterol metabolism, oxidative stress, and inflammatory response are important factors to promote the development and progression of liver cancer. However, some recent studies have found that statins have an adverse effect on the treatment of some liver cancer patients. This article elaborates on the role of statins as a “double-edged sword” in the treatment of liver cancer and related molecular mechanisms.

Contracture and spasticity of ankle joints were major sources of disability in neurological impairment including stroke and cerebral palsy, etc. The manual stretching used in physical therapy might be laborious and time-consuming to the therapists and the outcome was dependent on the experience and the subjectiveend feelingof the therapists. A device was developed that could safely stretch the an-kle joint to its extreme positions with quantitative control of the resistance torque and stretching velocity. Furthermore, it could satisfy a strong need for quantitative and objective measures of the impairment and rehabilitation outcome. This was just the meaning intelligent stretching referred to. This article described the origin of the concept of intelligent stretching and its definition, operational principle, and su-periority and weakness, as well as its application in ankle joint spasticity and contracture in patients with stroke and cerebral palsy.

Objective:To analyze the hotspots of international acupuncture research; To evaluate the influence of each hotspot; To explore its development trend.Methods:Acupuncture research related literature was retrieved from the Web of Science core database from January 1, 2019 to January 1, 2022. 42 highly cited literature was extracted using BICOMB 2.01 software, and a 42×42 co-occurrence matrix was constructed. A co-citation cluster analysis figure was drawn with SPSS 26.0 software. The CPT values of each hotspot identified in the cluster figure were computed using the formula CPT=(C/P)/T=C/(P·T). Bubble charts were drawn to show each hotspot's annual publication of articles.Results:Totally 23 research hotspots were identified, including consensus on the quality of evidence and recommendation intensity, assessment of the efficacy of acupuncture for chronic pain and analgesic mechanisms of acupuncture. The bubble chart showed that the annual attention of 23 hotspots varied, with 14 hotspots increasing year by year, 5 hotspots remaining stable, and only 4 hotspots decreasing year by year.Conclusions:The study has found that the direction of acupuncture research in the past three years focuses on acupuncture indication research, acupuncture mechanism research and evidence-based methodology research. China is the main contributor to the expansion of acupuncture indication research. The international trend of acupuncture development is obvious. Chinese acupuncture research faces greater competitive pressure, and the influence of core papers is insufficient.
