Objective To analyze the expression of synaptophysin (SY) in hippocampal dentate gyrus of rats with hypoxic-ischemic brain damage(HIBD) after the injection of bone marrow stromal cells(BMSCs) and its supernatant into the lateral ventricle and to explore the mechanism of potential effects. Methods Eighty 7-day-old sprague-dawley(SD) rats were randomly divided into sham group, control group, cell group and supernatant group, with 20 rats in each group. The HIBD model was established via the ligation of left carotid arteries followed by 2-hour hypoxia. One week later, control group was injected with 0.01 mol/L PBS via the left ventricle. Meanwhile, cell and supernatant group were injected with BMSCs and supernatant harvested from BMSC culture, respectively, via the same route. For spam group, the left carotid arteries were separated but not ligated, and no hypoxia treatment was imposed on this group. They also received 0.01mol/L PBS injection one week post surgery. After 8 weeks, the expression of SY in the dentate gyrus of rats was measured. Results Compared with sham group, model group showed significantly lower IOD (integral optical density) of SY positive material in the dentate gyrus(P < 0.05). Compared with model group, supernatant group and cell group exhibited significantly increased IOD values (P < 0.05), but there was no significant difference between cell group and supernatant group (P > 0.05). Conclusions BMSCs and supernatant injected via the lateral cerebral ventricle can increase SY expression in the hippocampal dentate gyrus of HIBD rats and promote synapse formation. The mechanism of this effect may be related to cytokine secretion by BMSCs which promotes synapse formation.

Objective : To discuss the changes of serum lipoprotein phospholipase A2 (Lp - PLA2) and c-reactive protein (CRP) levels in atorvastat in treatment for the patients with periodontitis and hyperlipidemia. Methods : 148 patients with periodontitis and hyperlipidemia were involved, and divided into basic group (foundation treatment, 82 cases) and statin group (foundation treatment plus 20 mg atorvastatin treatment, 66 cases). 40 healthy cases from the medical center health personnel were selected as the healthy group. Attachment levels (AL), bleeding index (BI), serum total cholesterol (TC), triacylglycerol (TG), Lp - PLA2, and CRP levels were checked and compared before and after 6 months of treatment. Lp - PLA2 and CRP were checked by enzyme linked immunosorbent assay (ELISA), and their relationship were analyzed by the method of Pearson. Results: When the disease group were compared with the healthy group, the statistics were as follows: AL（3.92 ± 0.51 mm vs 0.42 ± 0.06 mm）, BI（2.81 ± 0.48 vs 0.34 ± 0.05）, TC（5.27 ± 0.83 mmol/L vs 4.02 ± 0.62 mmol/L）, TG（2.67 ± 0.41 mmol/L vs 0.93 ± 0.17 mmol/L）, Lp-PLA2（243.57 ± 58.71 μg/L vs 132.24 ± 34.27 μg/L）, CRP（9.72 ± 3.27 μg/L vs 3.21 ± 0.87 μg/L）, and the statistics of disease group were significantly higher than the healthy group with a significant difference (P< 0.05). When Statin group was compared with basis group, the statistics were as follows: AL（3.70 ± 0.10 mmvs 3.78 ± 0.11 mm）, BI（1.05 ± 0.28 vs 1.43 ± 0.32）, TC（3.82 ± 0.67 mmol/L vs 4.51 ± 0.71 mmol/L）, TG（1.30 ± 0.29 mmol/L vs 1.83 ± 0.34 mmol/L）, Lp-PLA2（157.43 ± 40.18 μg/L vs 199.43 ± 47.24 μg/L）, CRP（4.21 ± 3.02 μg/L vs 6.37 ± 3.28 μg/L）, and the statistics of statin group were lower than that in basis group with a significant difference (P< 0.05). Pearson analysis showed Lp-PLA2 and CRP levels were positively correlated (r = 0.672, P< 0.05). Conclusion It shows the changes of Lp- PLA2 and CRP level were related with the clinical conditions of periodontitis combined with hyperlipidemia, and atorvastatin therapy can effectively reduce the body's blood lipid levels, and improve the treatment effects of periodontitis combined with hyperlipidemia.

The theory of "Yang transforming Qi while Yin constituting form" in the Huangdi's Internal Classic is derived from the application， transformation， movement， and balance of Tao. It is highly condensed， revealing the true meaning of Tao and guiding the changes and progress of all natural things， including diseases. Therefore， the appearance of various physical diseases is the manifestation of Yin-Yang Qi transformation. Sweat pore， formed by the Qi transformation of Yin and Yang， is the nourishing and regulating system. It serves as the hub and channel， assisting in the flow and transformation of Qi， facilitating the exchange of material， energy， and information with the outside world. With sweat pore as the hub and based on the macro-control and holistic thinking of "Yang transforming Qi while Yin constituting form"， this paper explores the microscopic mechanisms underlying chronic liver disease. In combination with the roles of mitochondria， exosomes， and the ultraliver sieve structure in the formation and progression of chronic liver disease， this paper elucidates the close internal relationship between the disease's initial quality， symptom signs， and its physiological and pathological functions under the guidance of this theory. Modern studies have shown that autophagy， intestinal flora disorders， glucose and lipid metabolism disturbances， activation of inflammatory factors， ferroptosis， and other microscopic pathological mechanisms are involved in the occurrence and development of chronic liver disease. The common connotation of the Yin-Yang concept in traditional Chinese medicine （TCM） and the pathological mechanisms in modern medicine is deeply analyzed. The corresponding relevant microscopic mechanisms and the guiding role of the theory of "Yang transforming Qi while Yin constituting form-sweat pore" in the management of chronic liver disease are summarized. Wind medicine promotes growth and transformation through sweat pore. The combination of pungent and sweet medicines facilitates Yang and disperse Yin. The formulas， combining the characteristics of wind medicine and pungent and sweet medicines， fit the principle of "Yang transforming Qi while Yin constituting form-sweat pore". This paper combines both macro and micro perspectives to explain the scientific connotation and microscopic mechanisms of chronic liver disease based on the theory of "Yang transforming Qi while Yin constituting form-sweat pore"， and explore the prevention and treatment of chronic liver disease through the principles， methods， prescriptions， and medicines featured by combination of pungent and sweet medicines， facilitating Yang， activating sweat pore， and dispersing Yin， providing new ideas and reference for the clinical treatment of chronic liver disease.

Hepatic fibrosis is a common complication of chronic liver disease， seriously affecting patients' quality of life and leading to severe consequences such as cirrhosis and liver cancer. Modern medicine has made progress in the treatment of hepatic fibrosis， while it still faces certain challenges and limitations. Therefore， seeking new therapeutic strategies is of great clinical significance. The nuclear factor-κB （NF-κB） signaling pathway plays a role in regulating inflammation and immune responses. Recent studies have shown that the NF-κB signaling pathway plays a key role in the occurrence and development of hepatic fibrosis. The abnormal activation of the NF-κB signaling pathway leads to the overexpression of genes related to liver inflammation and fibrosis， thereby promoting the development of hepatic fibrosis. Traditional Chinese medicine （TCM） is a traditional treatment method with unique advantages and potential. In recent years， increasing studies have proved that TCM can treat hepatic fibrosis by regulating the NF-κB signaling pathway. The active ingredients in Chinese herbal medicines can intervene in the activation of the NF-κB signaling pathway to inhibit inflammatory responses， thereby reducing the severity of hepatic fibrosis. This article reviews the mechanisms of TCM in treating hepatic fibrosis via the NF-κB signaling pathway and evaluates the efficacy and discusses the clinical application prospects of relevant Chinese herbs and formulae， aiming to provide references for further research and clinical practice.
