Hypertrophic obstructive cardiomyopathy(HOCM)is a hereditary cardiac disorder characterized primarily by septal hypertrophy and left ventricular outflow tract obstruction.Traditional therapeutic modalities,such as medications and surgeries,do not yield satisfactory outcomes in a subset of patients.The advancements have been made in novel treatments,including new drugs and percutaneous intramyocardial septal radiofrequency ablation(PIMSRA),still need further observation to obtain long-term efficacy and safety.In recent years,stereotactic body radiation therapy(SBRT)has emerged as an innovative non-invasive approach for treating HOCM.Studies indicate that SBRT allows for precise targeting of the hypertrophied septal region,causing both direct and indirect damage to targeted myocardial cells.This can alleviate left ventricular outflow tract obstruction and myocardial ischemia,fulfilling the therapeutic objective.For those with HOCM who neither respond well to medications nor are surgical candidates,SBRT offers a potential new therapeutic alternative.However,the latent risks of radiation therapy persist,such as the onset of radiation-induced heart disease(RIHD).The preliminary investigations guarantee the safety and feasibility of SBRT in HOCM management,an increased volume of clinical studies and prolonged follow-up data are essential to evaluate its real efficacy and potential hazards.In addition,research regarding the therapeutic mechanisms of SBRT for HOCM,optimal dosages and treatment durations,indications and contraindications,prevention of complications,and enhancing the precision of radiation therapy,still needs to be further exploration,to determine the best therapeutic strategies.

ObjectiveTo study the effect of total flavone of Litchi Semen （TFL） on proliferation， apoptosis， migration， and invasion of hepatoma cells HepG2. MethodMethyl thiazolyl tetrazolium colorimetric （MTT） assay was used to detect the effect of different-dose TFL and cisplatin on the proliferation of HepG2 cells. TdT-mediated dUTP nick-end labeling （TUNEL） assay was used to detect the effects of low， medium， and high-dose （70， 140， 210 mg·L^-1） of TFL and cisplatin （60 mg·L^-1） on the apoptosis of HepG2 cells， thus selecting the optimal dose of TFL for the follow-up experiment. HepG2 cells were divided into a blank group， a TFL group （140 mg·L^-1）， a TFL+XL019 group （140 mg·L^-1 TFL+0.5 μmol·L^-1 XL019）， and a TFL+TPI-1 group （140 mg·L^-1 TFL+1 μmol·L^-1 TPI-1）. The effect of TFL on migration and invasion of HepG2 cells were examined by wound healing test and Transwell invasion assay， and the effect of TFL on the expression of epithelial-mesenchymal transition （EMT） marker in HepG2 cells were examined by cell immunofluorescence assay. Western blot was used to detect the expression of key proteins in Janus kinase 2（JAK2）/signal transducer and activator of transcription 3 （STAT3） signaling pathway after the intervention by TFL. ResultMTT assay showed that the proliferation of HepG2 cells was significantly inhibited by TFL and cisplatin at 24 and 48 h as compared with blank group （P<0.01）， and the half maximal inhibitory concentration （IC₅₀） of TFL on HepG2 cells was （136.7±2.40） mg·L^-1 at 24 h and （106.8±1.11） mg·L^-1 at 48 h. The IC₅₀ of cisplatin on HepG2 cells was （58.48±2.04） mg·L^-1 at 24 h and （5.15±0.56） mg·L^-1 at 48 h. The results of TUNEL assay showed that TFL induced apoptosis of HepG2 cells. The optimal dose of TFL was 140 mg·L^-1. The results of wound healing test showed that compared with the blank group， the TFL group， TFL+XL019 group， and the TFL+TPI-1 group significantly inhibited the migration of HepG2 cells （P<0.05， P<0.01）. As compared with the TFL group， the inhibitory effect of the TFL+XL019 Group was significantly increased （P<0.05）， while that of the TFL+TPI-1 group was significantly decreased （P<0.01）. The Transwell invasion assay showed that compared with the blank group， the TFL group， TFL+XL019 group， and the TFL+TPI-1 group significantly inhibited the invasion of HepG2 cells （P<0.01）. As compared with the TFL group， the inhibitory effect of the TFL+XL019 group was significantly increased （P<0.05）， while that of the TFL+TPI-1 group was significantly decreased （P<0.01）. The results of immunofluorescence showed the intervention of TFL up-regulated the expression of E-cadherin， and down-regulated the expression of Vimentin in HepG2 cells， which was stronger in the TFL+XL019 group and weaker in the TFL+TPI-1 group. The results of Western blot showed that compared with the blank group， the TFL group， TFL+XL019 group， and the TFL+TPI-1 group did not affect the expression of JAK2 or STAT3 protein， but significantly decreased the expression levels of phosphorylatied （p）-JAK2 and p-STAT3 （P<0.05， P<0.01）. As compared with the TFL group， the expression levels of p-JAK2 and p-STAT3 in the TFL+XL019 group were significantly decreased （P<0.01）， while those in the TFL+TPI-1 group were significantly increased （P<0.01）. Compared with the blank group， the TFL group significantly increased the expression level of Src-homology domain 2 containing protein tyrosine phosphatase-1（SHP-1） with sh2 domain （P<0.01）. ConclusionTFL has the effects of inhibiting the proliferation， promoting apoptosis of HepG2 cells， and reversing the EMT process of HepG2 cells to reduce the migration and invasion， which are presumably related to the activation of SHP-1 by TFL to block JAK/STAT3 signaling pathway.

Objective: To explore the curative effect and safety of botulintum toxin A (BTX-A) on depressive disorder in patients with Parkinson′s disease (PD). Methods: Forty-two cases of PD with depression prospectively recruited in the Second Hospital Affiliated to Soochow University from August 2016 to November 2018 were divided into two groups: 28 patients in BTX-A group (administered with 100 U BTX-A injection on patients′ eyebrow, forehead, bilateral lateral canthus and temporal region at 20 loci), 14 patients in sertraline (control) group (administered with 50-100 (55.36±14.47) mg/d sertraline). The scores of Hamilton Depression Rating Scale (HAMD), Self-rating Depression Scale (SDS), Hamilton Rating Scale for Anxiety (HAMA), Self-rating Anxiety Scale (SAS) after treatment for 2 weeks, 4 weeks, 8 weeks and 12 weeks were compared with the scores of each emotional rating scale for baseline respectively. Meanwhile, the differences in the scores of each emotional scale between the two treatment groups were compared. In addition, the remission rates of depression and anxiety (defined as HAMD, HAMA scores<7) at each follow-up time point between the two groups were compared to evaluate the efficacy and safety of BTX-A in the treatment of PD patients with depression. Results: The scores of HAMD, HAMA, SDS, SAS in the BTX-A group and the sertraline group reduced compared to baseline after treatment (at the 2nd, 4th, 8th, 12th weeks). The scores of HAMD and SDS in the BTX-A group (HAMD scores: F=12.930, P<0.01; SDS scores: F=5.022, P=0.001) and those in the sertraline group (HAMD scores: F=2.883, P=0.030; SDS scores: F=3.427, P=0.013) were significantly lower compared to baseline, but there was no statistically significant difference in the scores of HAMD and SDS between the two groups (P>0.05). HAMD score showed that the remission rate of depression in the BTX-A group (17.9% (5/28), 35.7% (10/28)) was higher than that of the sertraline group (2/14, 4/14) at the 2nd and 4th weeks. At the 8th and 12th weeks, the remission rate of depression in the sertraline group (7/14, 9/14) was higher than that of the BTX-A group (46.4% (13/28), 53.6% (15/28)). There was no statistically significant difference in remission rate of depression between the two groups at each follow-up time point (P>0.05). There was no statistically significant difference in HAMD scores between males and females in the BTX-A group (P>0.05). Two of the 28 patients in the BTX-A group had frown muscle stiffness, which lasted for two weeks and improved in one month. Two patients in the sertraline group had headache and dizziness, and two patients had dry mouth and nausea, which improved after two weeks. There was no statistically significant difference in the incidence of adverse reactions between the two groups (P=0.197). Conclusion BTX-A intraocular facial muscle injection can significantly improve the depressive symptoms of PD patients, and the effect lasts for a long time, with low incidence of side effects and high safety, which can be considered as a safe and effective new method for PD patients with depressive symptoms.
