Objective To observe the effect of oral motor exercise on the feeding behaviour of autistic children. Methods 59 children with autism were assigned to control group (n=29) and exercise group (n=30). The control group received diet intervention, while the exercise group received oral motor exercises in addition. Both groups were assessed with questionnaire related to children's diet before and after treatment. Results Bad feeding behaviors such as little eating, overlength eating, picky eating, partial eating, refuse to eat significantly improved after treatment in the exercise group (P<0.05), and improved more than in the control group (P<0.05). Stereotyped feeding behavior improved after treatment in both groups (P<0.05) and there was no difference between 2 groups (P>0.05). Conclusion Oral motor exercises may improve the feeding behaviour of autistic children.

Objective To observe the effect of low tidal volume lung protective ventilation management strategy on postoperative outcome of elderly patients with poor pulmonary function after abdominal surgery.Methods Eighty patients of poor pulmonary function undergoing open gastrointestinal surgery,male 64 cases,female 16 cases,aged over 65 years old,ASA physical status Ⅱ or Ⅲ,NYHA cardiac function Ⅱ or Ⅲ grade,expected operation time 2-4 h were screened.The patients were randomly divided into 2 groups: protective ventilation management group (group P) and conventional mechanical ventilation group (group C),40 cases in each group.Multi-mode anesthetic management was performed in both groups.The respiratory parameters were adjusted according to the group after tracheal intubation,and the respiratory rate was adjusted to maintain PETCO2 35-45 mm Hg.The blood gas evaluated postoperative oxygen and postoperative spontaneous breathing recovery time,recovery time,extubation time,PACU time,gastrointestinal function recovery time,ambulation time,hospital stay and cost of hospitalization were recorded.The occurrence of major complications were observed at 30 days after surgery.Results PaO2 of group C was significantly decreased at 1 and 3 days after surgery than that before operation (P<0.05),PaCO2 of group C was significantly higher at 1 and 3 days after surgery than that of group P (P<0.05);PACU residence time of group P was (76.63±29.72) min,significantly shorter than that of group C [(93.80±42.90) min] (P<0.05);The difference spontaneous breathing recovery time,awake time,extubation time,exhaust time,ambulation time,postoperative hospitalization time and hospitalization expenses of two group was not statistically significant.Within 30 d after operation,2 cases (5%) of respiratory failure patients,3 cases (7.5%) of pneumonia in group P;5 cases (12.5%)of respiratory failure patients,3 cases (7.5%) of pneumonia,postoperative hemorrhage in 1 cases (2.5%) and 1 cases (2.5%) delirium in group C,there was no significant difference of the main complications in 30 d after operation between two groups.Conclusion Under the condition of this research,low tidal volume lung protective ventilation management strategy can improve elderly patients with poor pulmonary function after abdominal surgery postoperative oxygen and help to reduce the occurrence of postoperative adverse reactions.

Objective To investigate the effects of surface anesthesia on assisted balloon dilatation when treating dysphagia caused by radiotherapy for nasopharyngeal carcinoma.Methods Fifty-four patients with dysphagia after radiotherapy were divided randomly into an anesthesia group and a non-anesthesia group.The anesthesia group received anesthetics before treatment while the non-anesthesia group did not.All of the patients were treated with low-frequency electrical stimulation and assisted balloon dilatation for 3 weeks.They were then assessed using videofluoroscopy and self-reports of difficulty in swallowing before and after the treatment.Results After the treatment, significant improvement was observed in pharyngeal delay time, in cricopharyngeal opening, and in laryngeal elevation and forwardness.There was also a significant decrease in self-reported swallowing difficulty and failed swallows in both groups compared with before the treatment.The improvements in the non-anesthesia group were significantly greater than in the anesthesia group.After the treatment, the average aspiration rate of the anesthesia group was significantly higher than before treatment and higher than that of the non-anesthesia group.The improvement in oral intake of the non-anesthesia group was significantly better than that of the anesthesia group.Conclusion Balloon dilatation and low-frequency electrical stimulation have a synergistic effect and can improve patients' swallowing after radiation-induced cranial nerve damage, thus promoting survival.Assisted balloon dilatation without anesthesia has a better effect than when surface anesthesia is used.

Objective: To evaluate the relationship between bolus volume and hyoid displacement in dysphagia patients with nasopharyngeal carcinoma after radiation therapy. Methods: Twenty-three nasopharyngeal carcinoma patients with dysphagia were recruited and their swallowing of 3, 5, 10 and 20ml of liquid food was studied fluoroscopically. The vertical and horizontal displacement of the hyoid as well as its time in motion were measured, and the relationship between the bolus volume, hyoid displacement and time in motion time was evaluated. Results: The largest vertical displacement of the hyoid (1.01±0.65cm) was observed when swallowing a 10ml bolus. The hyoid showed the smallest average horizontal displacement (0.39±0.34cm), when swallowing a 3ml bolus. The average motion time of the hyoid was (2.11±0.65) seconds. It was shorter when swallowing a 10 or 20ml bolus than when dealing with a smaller one. Hyoid motion time was negatively correlated with the horizontal displacement of the hyoid bone, and the volume of a swallow was negatively correlated with the hyoid motion time but positively correlated with the penetration-aspiration scale score. Conclusion Bolus volume affects hyoid displacement and hyoid motion time in nasopharyngeal carcinoma patients with dysphagia after radiation therapy. For patients with a penetration-aspiration scale score of 5 or less, the optimum bolus volume is 5 to 10ml.

Non-small cell lung cancer(NSCLC)is one of the most prevalent and deadliest cancers worldwide.While the use of targeted therapies and immunotherapies in precision medicine has improved outcomes for some patients,a significant portion of individuals still fail to benefit,emphasizing the need to investigate the underlying mechanisms of resis-tance.Survival analyses have shown that NSCLC patients with SMARCA4 mutations often have poor prognoses.SMARCA4,the core ATPase subunit of the SWI/SNF chromatin remodeling complex,plays a critical role in regulating gene transcription by modifying chromatin accessibility.This influences essential cellular processes such as differentiation and cell cycle regula-tion,and SMARCA4 is widely regarded as a tumor suppressor.This review will explore the role of SMARCA4 mutations in tumor progression,its clinicopathological features in NSCLC,its impact on treatment outcomes,and potential therapeutic strategies.

Liver cancer is a malignant tumor with a high mortality rate.With the continuous development of targeted drugs,immunotherapy and other technological means,translational therapy has become a consensus in the treatment of advanced liver cancer.The liver's inherent immune tolerance,tumor tissue,and various immune components constitute a dynamically changing liver cancer microenvironment.The immune escape in the microenvironment of liver cancer is the main obstacle to current immunotherapy.Cellular immunity is an important component of anti-tumor immunity,and the status and function of immune cells are closely related to cancer prognosis.This article reviews the progress of tumor infiltrating lymphocytes in the tumor microenvironment of hepatocellular carcinoma,in order to benefit the exploring of targeted antitumor therapy.

ObjectiveThe antitumor activity of sesquiterpenoid M36 isolated from Myrrha against human hepatoma HepG2 cells was investigated in this study. MethodHepG2 cells were treated with M36 at different concentrations （0， 2， 4， 6， 8， 10 μmol·L^-1）. Firstly， the effects of M36 on the proliferation of human hepatoma HepG2 cells were detected by methyl thiazolyl tetrazolium （MTT）， colony formation assay， and EdU proliferation assay. Hoechst staining， flow cytometry analysis， and Western blot were used to explore the effect of M36 on the apoptosis of human hepatoma HepG2 cells. Acridine orange staining and western blotting were used to examine the effect of M36 on autophagy in HepG2 cells. Finally， Western blot was used to detect protein expression of cancer-related signaling pathways. ResultCompared with the blank group， M36 treatment significantly inhibited the proliferation of human hepatoma HepG2 cells （P<0.01）， and the half inhibitory concentration （IC₅₀） value of M36 for 48 h was 5.03 μmol·L^-1， in a dose- and time-dependent manner. M36 was also able to induce apoptosis and autophagy in human hepatoma HepG2 cells. After treatment with 8 μmol·L^-1 M36 for 48 hours， the apoptosis rate of HepG2 cells was （42.03±9.65）% （P<0.01）. Compared with the blank group， HepG2 cells treated with 4 and 8 μmol·L^-1 M36 for 48 h had a significant increase in cleaved poly ADP-ribose polymerase （cleaved-PARP） protein levels （P<0.01）. Acridine orange staining showed that autophagy was significantly activated in HepG2 cells treated with 4 and 8 μmol·L^-1 M36 for 48 h compared with the blank group （P<0.01）， which was further verified by the up-regulation of microtubule-associated protein 1 light chain 3 Ⅱ （LC3 Ⅱ）. Western blot results showed that compared with the blank group， the levels of phosphorylated extracellular regulated protein kinase （p-ERK）， phosphorylated p38 mitogen-activated protein kinase （p-p38 MAPK）， phosphorylated c-Jun N-terminal kinase （p-JNK）， and its downstream nuclear transcription factors c-Jun and p-c-Jun protein were significantly increased in M36 group （P<0.05， P<0.01）. The mechanism may be related to the up-regulation of MAPK signaling pathway. ConclusionThe sesquiterpenoid M36 isolated from Myrrha inhibits the proliferation of human hepatoma HepG2 cells and promotes apoptosis and autophagy， which may be related to the activation of the MAPK signaling pathway.
