This study focuses on the core pathology of sinew wei （痿）， which is mainly characterized by the fai-lure of qi and blood to nourish the sinews. A mechanical-biological response framework is constructed with mitochondria as a key component， explaining the modern interpretation of the disease location of sinew transmitting to qi and blood pathology. Mechanical loading， as a physical stress stimulus applied to the body， manifests primarily as passive loading formed by external forces such as massage， and active loading resulting from voluntary muscle contractions， such as dao yin （导引）. Mechanical loading can regulate mitochondrial function through two pathways， mechanical signal transduction and metabolic demand-driven regulation. Skeletal muscle mitochondrial dysfunction is regarded as the core microscopic basis of qi imbalance in sinew wei， highlighting the intrinsic connection between qi and mitochondrial energy metabolism， as well as between blood and microcirculatory efficiency. Accordingly， distinct regulatory patterns of mechanical loading are identified. Wei associated with qi stagnation may correspond to mitochondrial network fragmentation and can be treated by regulating qi through passive loading， such as tuina， to restore mitochondrial dynamics. In contrast， wei caused by qi deficiency is attributed to insufficient mitochondrial biogenesis and may be treated by tonifying qi through active loading， such as dao yin， to promote mitochondrial biogenesis. This framework reveals the biological differences in mitochondrial regulation induced by distinct mechanical loading modalities and provides a microscopic mechanism-based explanation for the principle of "treating the same disease with different methods" in sinew wei.

Meningioma is the most common primary intracranial tumor,of which about 20％are high-grade tumors,with a high recurrence rate after surgery and poorly controlled by radiotherapy,requiring adjuvant pharmacological treatment.Cytotoxic drugs were applied at the beginning,but the efficacy was poor with significant side effects.Subsequently,targeted drugs such as tyrosine kinase inhibitors and somatostatin analogs were used for treatment,and the prognosis of meningioma patients was improved.With the development of new technologies such as high-throughput sequencing,more potential targets have been revealed.There exists a suppressive immune microenvironment within meningiomas,and modulation of lymphocytes and myeloid cells can rescue the intrinsic immune function of the tumor,and relevant clinical trials are in progress.This article reviewed the research progress of pharmacological treatment of meningiomas,and the current situation and prospects of drug therapy ware discussed and prospected.

Objective:To investigate the current situation of cytomegalovirus (CMV) infection in infants in Lishui, and summarize the related factors of CMV infection, evaluate its influence on the growth and development of infants, and provide evidence for the prevention and control of CMV infection.Methods:In this study, 2 254 cases of infants admitted in pediatric ward in Lishui Maternal and Child Health Hospital, Qingtian County People′s Hospital, Suichang County People′s Hospital, Qingyuan County People′s Hospital from January 1, 2015 to December 31, 2017 with integral clinical data were selected. All the babies were followed up from the time when they were born to 1 year old. The serum CMV antibody and the urine CMV-DNA were screened, the general situation and clinical features of CMV infection were summarized, and the relevant factors of infants CMV infection were analyzed and screened by the single factor and multiple factors analysis. They were followed up to 1 year old to clarify the influence of CMV infection on the growth and development of infants.Results:From 2015 to 2017, the total positive infection rate of CMV-IgM in infants under 1 year old in Lishui was 10.43%(235/2 254), and CMV-IgM positive infection decreased year by year. The positive rate of CMV-IgG did not change significantly with time. The positive rate of CMV-IgM was the highest at 1—3 months, and up to 15.29% (61/399). The positive rate of CMV-IgM decreased with the age of the babies. The positive rate of CMV-IgG increased with the age of the babies. The positive rate of CMV-IgM in infants showed no significant difference in gender ( P>0.05). The positive rate of CMV-IgM was higher in men than that in women [65.43% (810/1 238) vs. 55.51% (564/1 016)], and there was significant difference ( P<0.05). The gestational age of the infected group was lower than that of the non-infected group [(37.41 ± 1.63) weeks vs. (38.97 ± 0.97) weeks], and the breast-feeding rate of the infected group was higher than that of the non-infected group [57.87%(136/235) vs. 40.00%(40/100)], and there were significant differences ( P<0.05). Thrombocytopenia, the increase of transaminase, necrotizing enterocolitis of newborn, and hepatosplenomegaly of infected group is higher that of the non-infected group [18.72%(44/235) vs. 1.00% (1/100), 29.36% (69/235) vs. 13.00% (13/100), 26.81% (63/235) vs. 10.00% (10/100), 9.79% (23/235) vs. 0], and there were significant differences ( P<0.05). Gestational age and breast-feeding were possible risk factors for CMV infection in infants under 1 year old ( P<0.05). There was no significant difference in height, weight, head circumference and intelligence score between the infected group and the non-infected group at the age of 1 year ( P>0.05). The total abnormal rate of hearing development and the abnormal detection rate of B-ultrasound in the infected group were higher than those in the non-infected group [13.62%(64/470) vs. 1.00%(2/200), 6.38%(15/235) vs. 0], and there were significant differences ( P<0.05). Conclusions:The CMV active infection rate of infants under 1 year old in Lishui is relatively high and decreases year by year. It decreases with the prolongation of birth time, and there is no gender difference. Gestational age and breast-feeding are the risk factors for active CMV infection in infants. CMV infection affects the hearing development and the brain development of infants under 1 year old, which is the main cause of hepatitis. It is necessary to pay attention to the prevention of CMV infection, strengthen maternal perinatal health care, and strengthen the screening of CMV infection in high-risk groups.
