Objective: To investigate the effects of C1q tumor necrosis factor⁃related protein 3 (CTRP3) ⁃enhanced Sendai virus (SeV) vector⁃overexpressing Gata4 , Mef2c , and Tbx5 (SeVGMT) in the treatment of myocardial in⁃farction (MI) mice and to analyze whether ubiquitin carboxyl⁃terminal hydrolase L1 (UCHL1) mediates this thera⁃peutic pathway. Methods: The mice were divided into 7 groups ( n = 12) : Sham group , MI group , SeVGMT group , CTRP3⁃Lv group , UCHL1 ⁃sh group , SeVGMT + CTRP3⁃Lv group , and SeVGMT + CTRP3⁃Lv + UCHL1 ⁃sh group. In the Sham group , only the skin was incised without ligation , while the coronary artery was ligated 2 - 3 mm below the left atrial appendage in mice in other groups. PBS was injected at three points in the myocardial infarction boundary in the Sham and MI groups 30 minutes after ligation. Mice in other groups were injected with SeVGMT , CTRP3-Lv , or UCHL1-sh according to their grouping. Four weeks after treatment , fractional shortening (FS) , ejection fraction (EF) , left ventricular end-diastolic diameter (LVIDd) , left ventricular end-systolic diameter (LVIDs) , heart rate (HR) , mean arterial pressure (MAP) , serum creatine kinase isoenzyme MB (CK-MB) , myocardial troponin I ( cTnI) and lactate dehydrogenase ( LDH) levels , and myocardial tumor necrosis factor-α (TNF-α ) , interleukin-1β (IL-1β) and interleukin-6 (IL-6) levels in mice were detected. The pathological changes of myocardial tissue were detected by 2 , 3 , 5-triphenyltetrazolium chloride ( TTC) , hematoxylin-eosin ( HE) , Masson trichrome and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. The mRNA expressions of CTRP3 and UCHL1 were detected by qRT-PCR. The protein expressions of CTRP3 , UCHL1 , collagen Ⅰ , collagen Ⅲ , Bcl-2-associated X (Bax) and B-cell lymphoma/leukemia-2 (Bcl-2) in myocardial tissue were detected by Western blot or immunohistochemical staining. Results: Compared with SeVGMT group and CTRP3-Lv group , the levels of EF , FS , HR and MAP in SeVGMT + CTRP3-Lv group increased (P < 0. 05) . The levels of LVIDd , LVIDs , CK-MB , cTnI , LDH , TNF-α , IL-1β and IL-6 decreased (P < 0. 05) . MI area , fibrosis area and TUNEL positive rate decreased (P < 0. 05) , the protein levels collagen Ⅰ , collagen Ⅲ and Bax decreased (P < 0. 05) , and Bcl-2 protein levels increased (P < 0. 05) . The mRNA and protein levels and relative staining intensity of CTRP3 and UCHL1 increased (P < 0. 05) . Compared with SeVGMT + CTRP3-Lv group , the addition of UCHL1-sh treatment ( SeVGMT + CTRP3-Lv + UCHL1-sh group) significantly weakened the influence of SeVGMT + CTRP3-Lv on the above indexes (P < 0. 05) . Conclusion CTRP3 mediated UCHL1 enhances the therapeutic effect of SeVGMT reprogrammed CFs on MI in mice.

Objective:To explore the effect of core muscle group training combined with balance cup therapy in patients with chronic nonspecific low back pain.Methods:From January 2017 to December 2019, convenience sampling method was used to select 130 patients with chronic nonspecific low back pain in Guangdong Province Foshan Hospital of Traditional Chinese Medicine. According to the random number table, patients were divided into core muscle group and combined treatment group, with 65 cases in each group. The core muscle group was given the Swiss ball to perform core muscle training in the order of sitting, double bridge, knee flexion double bridge, reverse bridge and push-ups. The combined treatment group was given a balance tank based on core muscle training, followed by flash tank, walking tank, and sitting tank treatment. After 4 weeks of intervention, we compared the scores of the Visual Analogue Scale (VAS) , Roland-Morris Disability Questionnaire (RMDQ) , Finger-Floor Distance (FFD) , and static and dynamic muscle endurance time, and the total effective rate of treatment between the two groups of patients.Results:After intervention, the scores of VAS, RMDQ and FFD of combined treatment group were lower than those of core muscle group, and the differences were statistically significant ( P<0.01) . The static and dynamic muscle endurance time of combined treatment group were higher than those of core muscle group, and the differences were statistically significant ( P<0.01) . The total effective rate of combined treatment group was 90.77% (59/65) , which was higher than 76.92% (50/65) of core muscle group, and the difference was also statistically significant ( P<0.05) . Conclusions:Core muscle training combined with balance cup therapy can reduce the degree of pain in patients with chronic nonspecific low back pain, improve waist dysfunction, waist flexibility and muscle endurance, and have good clinical effects.

In order to probe into the relationship between the TCM syndrome types and the five indices of fibrotic markers of liver in serum, the HA, hPC I , IV - C in 160 of liver cirrhosis patients induced by chronic hepatitis were examined. Results showed that the 5 indices in all TCM syndrome types were all higher than the control group, each with its specificity. The increased amplitude in the group of liver - stagnant, spleen - deficiency was the least one. It was also found that the 3 indices of liver fibrosis in the group of internal blockade of damp - heat were markedly increased; it was mainly the increase of HA, hPC I in the group of yin-deficiency of both liver - kidney and obstruction of collaterals by static blood; but it was mainly the increase of HA, W - C in the group of Yang - deficiency of spleen and kidney. This demonstrated that the above indices were of significance in TCM syndrome typing for chronic hepatic victims. Lingering of damp -heat may be the trigger factor for liver fibrosis in which blood stasis was present during the whole course of liver fibrosis.
