Objective To discuss whether acupuncture at Neiguan (PC 6) inhibits myocardial hypertrophy via monoamine neurotransmitters.Method Sixty female Sprague-Dawley rats were randomized into a control group, a model group, a sham electroacupuncture (EA) group, and an EA group, 15 cases in each group. The rat models of myocardial hypertrophy were developed by subcutaneous injection of Isoprenaline hydrochloride (ISO) for 14 d. The EA group was intervened by EA at Neiguan (PC 6), and the sham EA group was by EA at a sham acupoint [5 mm away lateral to Neiguan (PC 6). The Electrocardiogram (ECG) of each group was recorded, electron microscope was used to observe the microstructure of the rats’ myocardial tissues, and high performance liquid chromatography (HPLC) was adopted to detect the contents of catecholamines in myocardial tissues.Result The heart rate, R-R interval, ST-elevation, and the contents of catecholamines in rats’ myocardial tissues (adrenaline, noradrenaline, and dopamine) in the model group and sham EA group were significantly different from that in the control group (P<0.05). The heart rate, R-R interval, ST-elevation, and the contents of catecholamines in rats’ myocardial tissues (adrenaline, noradrenaline, and dopamine) of the EA group were significantly different from that of the model group (P<0.05).Conclusion EA at Neiguan (PC 6) can improve myocardial hypertrophy, which is related to the regulation of the topical neurotransmitters; it has provided laboratory evidences for the relationship between Neiguan (PC 6) and heart, i.e. the relationship between acupoints and internal organs.

Objective:To investigate the expression and clinical significance of effector T cell (Teff), regulatory T cell (Treg) and their cytokines in patients with vitiligo.Methods:84 patients with vitiligo (38 cases in stable stage, 46 cases in advanced stage) who were admitted to the Dermatology Department of the Dezhou People's Hospital between June 2018 and June 2019 and 30 healthy people (control group) were enrolled in the study. The levels of Teff subsets and Treg cells in peripheral blood were detected by flow cytometry. The levels of Teff subsets and Treg cells-associated cytokines were detected by enzyme-linked immunosorbent assay (ELISA). The relationship between Teff subsets and Treg cells levels in peripheral blood, relationship between Teff subgroups, Treg cells-associated cytokines and course of vitiligo, skin lesion area were analyzed.Results:The levels of T helper cell (Th)17 and Th22 in peripheral blood of vitiligo group were significantly higher than those of control group, while levels of Treg cells were significantly lower than control group ( P<0.05). Compared with the stable vitiligo group, the levels of Th17 and Th22 in peripheral blood were higher and levels of Treg cells were lower in the advanced vitiligo group ( P<0.05). Treg cell level was negatively correlated with Th17 cell level ( r=-0.303, P=0.001), and negatively correlated with Th22 cell level ( r=-0.200, P=0.033). The levels of serum interleukin (IL)-17 and IL-22 in vitiligo group were significantly higher than those in control group, while the level of transforming growth factor-β (TGF-β) was significantly lower than that in control group ( P<0.05). Compared with the stable vitiligo group, levels of serum IL-17 and IL-22 were higher and level of TGF-β was lower in the advanced vitiligo group ( P<0.05). Correlation analysis showed that levels of IL-17 and IL-22 were positively correlated with skin lesion area ( r=0.361, 0.288, P<0.05), and level of TGF-β was negatively correlated with skin lesion area ( r=-0.312, P<0.05). Conclusions:Teff/Treg cells are unbalanced in patients with vitiligo, showing obvious shift to Teff subsets. The progression of vitiligo may be related to Teff subsets and Treg cells-associated cytokines.

This study was aimed to evaluate impacts on immune regulation with spleen-strengthening and kidney-tonifying method among advanced malignant tumor patients. The enrolled advanced malignant tumor patients were randomly divided into the control group and the treatment group. The control group was treated with conventional treatment plan. The treatment group was treated with spleen-strengthening and kidney-tonifying Chinese herbs on the basis of conventional treatment plan for three months. Clinical effect, integral of clinical symptom (ICS), T-lym-phocyte subsets, and drug safety index were observed and detected before and after treatment. The results showed that the effective rate and response rate in the control group were 31.1% and 71.1%, respectively. And the effective rate and response rate in the treatment group were 54.2% and 85.4%, respectively. The treatment group was better than the control group (P< 0.05). Compared to the control group, the treatment group had obvious regulation on T-lymphocyte subsets. The improvement on ICS in the treatment group was better than the control group (P < 0.05). There was no obvious adverse reaction with the application of Chinese herbs. It was concluded that the spleen-strengthening and kidney-tonifying method can improve clinical effect, life of quality, and reduce adverse reaction a-mong advanced malignant tumor patients. Its mechanism may be through the regulation of immune function.

Aim To make a research of rats with focal cerebral ischemia/reperfusion injury on pathological changes in brain and the changes of AQP4 and related proteins, in order to explore the relationship between AQP4 and brain edema. Methods Adult male SD rats, weighting 250~300 g, were randomly divided in-to Sham group and cerebral ischemia/reperfusion ( I/R) injury model group. The I/R model group was di-vided into the I/R-6 h, 12 h, 24 h, 48 h-four time point groups. The animal model of the right MCA is-chemia/reperfusion was established by suture method in mature SD rats. The nerve symptom score was con-ducted in the corresponding time points. Then, the permeability of brain tissue was detected by EB stai-ning;TTC staining was conducted to observe the cere-bral infarction volume;the dry wet weight method was used to detect the changes of brain water content; im-munohistochemical( IHC) , WB and RT-PCR were ap-plied to detect the expression of AQP4 , and the related factors at different time points of the model rats after is-chemia-reperfusion around infarcts. Results Com-pared with the Sham group, then ever function score of the rats in I/R model groups were much higher. With the increase of the reperfusion time, the cerebral in-farction volume, brain tissue permeability and the brain water content were also increased. IHC results showed that AQP4 expression gradually rose with widen distribution. WB and RT-PCR results verified the in-creasing level of AQP4 expression. The detection of the related proteins expression showed apparent changes. The expression of MMP-9 was increased, while the Oc-cludin and JAM-1 expression showed a decreasing trend. The I/R-48 h model group showed the most ob-vious differences in the expression of the related pro-teins and mRNA ( P <0. 01 vs Sham, respectively ) . Conclusion Accompanied with the aggravating cere-bral injury after cerebral ischemia/reperfusion, the ex-pression of AQP4 and MMP-9 level were activated, while the degradation of TJPs, Occludin and JAM-1, was increased. These factors are combined to make the formation of brain edema. This study makes a further research on the formation mechanism of the early stage for cerebral edema on I/R model and offers a potential for intervention in the filed of looking for a reliable drug therapy on cerebral edema.
