In order to promote the innovative application of Sanjiao theory and Yingwei theory, this paper tries to apply the ''Sanjiao-Yingwei'' Qi transformation theory to the treatment of tumor diseases, integrating it with T cell exhaustion mechanism to elaborate on its scientific connotation and using network pharmacology and bioinformatics to elucidate the correlation between the anti-tumor mechanism of ''Sanjiao-Yingwei'' Qi transformation and T cell exhaustion. The ''Sanjiao-Yingwei'' Qi transformation function is closely related to the immunometabolic ability of the human body, and the ''Sanjiao-Yingwei'' Qi transformation system constitutes the immunometabolic exchange system within and outside the cellular environment. Cancer toxicity is generated by the fuzzy Sanjiao Qi, and the long-term fuzzy Sanjiao Qi is the primary factor leading to T cell exhaustion, which is related to the long-term activation of T cell receptors by the high tumor antigen load in the tumor microenvironment. Qi transformation malfunction of the Sanjiao produces phlegm and collects stasis, which contributes to T cell exhaustion and is correlated with nutrient deprivation, lipid accumulation, and high lactate levels in the immunosuppressed tumor microenvironment, as well as with the release of transforming growth factor-β and upregulated expression of programmed death receptor-1 by tumor-associated fibroblasts and platelets in the tumor microenvironment. Ying and Wei damage due to Sanjiao Qi transformation malfunction is similar to the abnormal manifestations such as progressive loss of exhausted T cell effector function and disturbance of cellular energy metabolism. Guizhi decoction, Shengming decoction, and Wendan decoction can correct T cell exhaustion and exert anti-tumor effects through multi-target and multi-pathways by regulating ''Sanjiao-Yingwei'' Qi transformation, and hypoxia inducible factor-1α (HIF-1α) may be one of the main pathways to correct T cell exhaustion. It was found that HIF-1α may be one of the important prognostic indicators in common tumors by bioinformatics. The use of the ''Sanjiao-Yingwei'' Qi transformation method may play an important part in improving the prognosis of tumor patients in clinical practice.

OBJECTIVE:At present,there are many reports on the related factors associated with the incidence of cervical spine instability in patients with rheumatoid arthritis,but there are problems such as small sample size and many confounding factors,and the research results of various studies on the same related factors are also different.This article analyzed the factors related to cervical spine instability in patients with rheumatoid arthritis by means of a systematic review. METHODS:Articles related to cervical spine instability in patients with rheumatoid arthritis were collected by searching both Chinese and English databases until March 2023.The outcome of cervical spine instability in patients with rheumatoid arthritis was used as the grouping criterion to abstract basic information,baseline patient characteristics,laboratory-related tests,medication use,and other relevant risk factors.Meta-analysis was done using Stata 14.0 software. RESULTS:(1)Sixteen relevant studies,all of moderate or above quality,were included,including seven studies with case-control studies and nine with cross-sectional studies.The overall incidence of cervical spine instability in patients with rheumatoid arthritis was 43.08%.(2)Meta-analysis showed:Related risk factors included female(OR=0.60,95%CI:0.44-0.82,P=0.002);age at disease onset(SMD=-0.52,95%CI:-0.86 to-0.18,P=0.003);duration of disease(SMD=0.58,95%CI:0.14-1.02,P=0.01);body mass index(OR=0.74,95%CI:0.63-0.88,P=0.001);rheumatoid factors positive univariate analysis subgroup(OR=1.33,95%CI:1.02 to 1.72,P=0.04),C-reactive protein(SMD=0.26,95%CI:0.16-0.35,P=0.00),erythrocyte sedimentation rate(SMD=0.15,95%CI:0.002-0.29,P=0.047),anti-cyclic-citrullinated peptide antibodies(OR=1.73,95%CI:1.19-2.51,P=0.004),28-joint Disease Activity Score(SMD=0.20,95%CI:0.04-0.37,P=0.02),destruction of peripheral joints(OR=2.48,95%CI:1.60-3.85,P=0.00),and corticosteroids(OR=1.91,95%CI:1.54-2.37,P=0.00)were strongly associated with the development of rheumatoid arthritis-cervical spine instability.Female and corticosteroid use were independently associated with the occurrence of rheumatoid arthritis-cervical spine instability. CONCLUSION:Based on clinical evidence from 16 observational studies,the overall incidence of rheumatoid arthritis-cervical spine instability was 43.08%.However,the incidence of cervical spine instability in rheumatoid arthritis patients varied greatly among different studies.Gender(female)and the use of corticosteroids were confirmed as independent correlation factors for the onset of cervical spine instability in patients with rheumatoid arthritis.The results of this study still provide some guidance for early clinical recognition,diagnosis,and prevention of rheumatoid arthritis-cervical spine instability.

ObjectiveTo explore the effect and possible molecular mechanism of Qinghua Yichang Formula (清化益肠方, QYF) in treating acute radiation-induced intestinal injury mice via NOD-like receptor thermal protein domain associated protein 3 (NLRP3). MethodsSixty C57BL/6J mice were randomly divided into control group, model group, pre-modeling medication group, post-modeling medication group, inhibitor group, and QYF plus inhibitor group, with 10 mice in each group.Except for the control group, the other five groups were irradiated with a single full dose to establish the acute radiation-induced intestinal injury mice model. The pre-modeling medication group and the QYF plus inhibitor group were continuously given 4 g/ml of QYF decoction by gavage before modeling, 0.2 ml each time, once a day for 7 days. The post-modeling medication group, pre-modeling medication group and QYF plus inhibitor group were given 4 g/ml of QYF decoction for 14 days after modeling. The control group, model group and inhibitor group were given 0.2 ml of normal saline once a day for 14 consecutive days. Two hours after irradiation, the inhibitor group and the QYF plus inhibitor group were given an intraperitoneal injection of 0.2 ml of the NLRP3 inhibitor MCC950 (concentration: 10 mg/kg), once every two days. To observe the pathological changes in intestinal tissues, hematoxylin-eosin (HE) staining was used. Western blotting and RT-qPCR were used to detect the protein and mRNA expression levels of NLRP3 in intestinal tissues. Immunohistochemistry was used to detect the expression level of NLRP3, Caspase-1 and GSDMD in intestinal tissues. The proportion of CD4+ and CD8+ T cells in the spleens of mice were detected by flow cytometry. ELISA was used to determine the levels of IFN-γ, IL-18, and IL-1β in mice serum. ResultsHE staining showed no lesions in the intestinal tissue of mice in the control group. The mice in the model group had shortened intestinal villi, thinned mucosal layers, multifocal mucosal necrosis in the lamina propria, and local neutrophil infiltration. The pathological damage of intestinal tissue of mice in each medication group was improved to varied degrees, among which the QYF plus inhibitor group showed most obvious improvement. Compared to those in the control group, the protein and mRNA expression levels of NLRP3 in the intestinal tissue of mice in the model group significantly increased, with higher NLRP3, Caspase-1, and GSDMD protein expression in the intestinal tissue, increased proportion of CD4+ T cells in spleen, decreased proportion of CD8+ T cells, and increased levels of IFN-γ, IL-18 and IL-1β in serum (P<0.05). Compared to those in the model group, the above indicators in the other medication groups were all improved (P<0.05).The NLRP3, Caspase-1, and GSDMD proteins in the pre-modeling medication group were lower than those in the post-modeling medication group (P<0.05); and the NLRP3 mRNA level in the QYF plus inhibitor group was lower than that in the inhibitor group (P<0.05). ConclusionQYF may play a role in preventing and treating acute radiation-induced intestinal injury by inhibiting the expression of NLRP3.

Objective:To explore the function of MDM2 and its relationship with p53 at the cellular level during H 2O 2 induced oxidative damage. Methods:MLE-12 HALI cell models were established using 0.5 mmol/L H 2O 2, and were divided into three groups: normal control group, H 2O 2 injury group, H 2O 2+MDM2 overexpressed group, and H 2O 2+MDM2 shRNA group. Infection of MLE-12 cells with adenovirus vector overexpressing and silencing MDM2; Using immunoprecipitation (Co-IP) to analyze the interaction between MDM2 and p53; Western blotting was used to detect the protein expression levels of MDM2, p53, Bcl-2, Bax, and cleared caspase-3 after HALI modeling; Measure the apoptosis rate of cells in each group. Results:After transcriptome sequencing,the p53 signaling pathway closely related to HALI. Compared with the normal group, the expression of MDM2 in the H 2O 2 injury group was lower ( P<0.05); Compared with the H 2O 2 injury group, overexpression of MDM2 resulted in a decrease in the apoptosis rate of MLE-12 cells ( P<0.05), a decrease in the expression levels of p53, Bax, and cleared caspase-3 proteins, and an upregulation of MDM2 and Bcl-2 protein expression ( P<0.05). Compared with the H 2O 2 injury group, when MDM2 was silenced, the cell apoptosis rate increased ( P<0.05), and the expression levels of p53, Bax, and cleared caspase-3 proteins were upregulated, while the expression levels of MDM2 and Bcl-2 proteins decreased ( P<0.05). Co-IP experiments showed that MDM2 binds to p53 protein. Conclusions:MDM2 can exert a protective effect on HALI by inhibiting MLE-12 cell apoptosis through the p53/Bcl-2/Bax axis.

Oral squamous cell carcinoma (OSCC) develops on the mucosal epithelium of the oral cavity. It accounts for approximately 90% of oral malignancies and impairs appearance, pronunciation, swallowing, and flavor perception. In 2020, 377,713 OSCC cases were reported globally. According to the Global Cancer Observatory (GCO), the incidence of OSCC will rise by approximately 40% by 2040, accompanied by a growth in mortality. Persistent exposure to various risk factors, including tobacco, alcohol, betel quid (BQ), and human papillomavirus (HPV), will lead to the development of oral potentially malignant disorders (OPMDs), which are oral mucosal lesions with an increased risk of developing into OSCC. Complex and multifactorial, the oncogenesis process involves genetic alteration, epigenetic modification, and a dysregulated tumor microenvironment. Although various therapeutic interventions, such as chemotherapy, radiation, immunotherapy, and nanomedicine, have been proposed to prevent or treat OSCC and OPMDs, understanding the mechanism of malignancies will facilitate the identification of therapeutic and prognostic factors, thereby improving the efficacy of treatment for OSCC patients. This review summarizes the mechanisms involved in OSCC. Moreover, the current therapeutic interventions and prognostic methods for OSCC and OPMDs are discussed to facilitate comprehension and provide several prospective outlooks for the fields.

Objective:To explore the effect of exercise prescription based on a progressive mode in treating elderly patients with lower limb dysfunction after deep burns.Methods:A randomized controlled trial was conducted. From January 2021 to January 2023, 60 elderly patients with lower limb dysfunction after deep burns who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University. The patients were divided into conventional rehabilitation group (30 cases, 17 males and 13 females, aged (65±3) years) and combined rehabilitation group (30 cases, 16 males and 14 females, aged (64±3) years) according to the random number table. For patients in both groups, the red-light treatment was started after the lower limb wounds healed or when the total area of scattered residual wounds was less than 1% of the total body surface area. After 2 weeks of red-light treatment, the patients in conventional rehabilitation group were given conventional rehabilitation treatments, including joint stretching, resistance, and balance training; in addition to conventional rehabilitation treatments, the patients in combined rehabilitation group were given exercise prescription training based on a progressive mode three times a week, mainly including dumbbell press, Bobath ball horizontal support, and high-level pulldown trainings. The training time for patients in both groups was 12 weeks. Before training (after 2 weeks of red-light treatment) and after 12 weeks of training, the upper limb and lower limb motor functions of the patients were evaluated using the simple Fugl-Meyer scale, the physical fitness of patients was evaluated using the simple physical fitness scale, and the patient's risk of falling was evaluated by the time consumed for the timed up and go test. The adverse events of patients that occurred during training were recorded. After 12 weeks of training, a self-designed satisfaction survey was conducted to investigate patients' satisfaction with the training effect. Data were statistically analyzed with independent sample t test, paired sample t test, Mann-Whitney U test, Wilcoxon signed rank test, and chi-square test. Results:Before training, the scores of upper limb and lower limb motor functions of patients between the two groups were similar ( P>0.05). After 12 weeks of training, the scores of upper limb motor function of patients in conventional rehabilitation group and combined rehabilitation group were significantly higher than those before training (with t values of -11.42 and -13.67, respectively, P<0.05), but there was no statistically significant difference between the two groups ( P>0.05). The score of lower limb motor function of patients in combined rehabilitation group was 28.9±2.6, which was significantly higher than 26.3±2.6 in conventional rehabilitation group ( t=-3.90, P<0.05), and the scores of lower limb motor function of patients in conventional rehabilitation group and combined rehabilitation group were significantly higher than those before training (with t values of -4.14 and -6.94, respectively, P<0.05). Before training, the individual and total scores of physical fitness of patients between the two groups were similar ( P>0.05). After 12 weeks of training, the balance ability score, walking speed score, chair sitting score, and total score of physical fitness of patients in conventional rehabilitation group and combined rehabilitation group were significantly increased compared with those before training (with Z values of -4.38, -3.55, -3.88, -4.65, -4.58, -4.68, -4.42, and -4.48, respectively, P<0.05), and the balance ability score, walking speed score, chair sitting score, and total score of physical fitness of patients in combined rehabilitation group were significantly increased compared with those in conventional rehabilitation group (with Z values of -3.93, -3.41, -3.19, and -5.33, P<0.05). Before training, the time consumed for the timed up and go test for patient's risk of falling in the two groups was close ( P>0.05). After 12 weeks of training, the time consumed for the timed up and go test for patient's risk of falling in combined rehabilitation group was (28.0±2.1) s, which was significantly shorter than (30.5±1.8) s in conventional rehabilitation group ( t=4.94, P<0.05). Moreover, the time consumed for the timed up and go test for patient's risk of falling in both conventional rehabilitation group and combined rehabilitation group was significantly shorter than that before training (with t values of 14.80 and 15.86, respectively, P<0.05). During the training period, no adverse events such as muscle tissue strain, edema, or falling occurred in any patient. After 12 weeks of training, the satisfaction score of patients with the training effect in combined rehabilitation group was 13.5±1.2, which was significantly higher than 8.5±1.4 in conventional rehabilitation group ( t=21.78, P<0.05). Conclusions:The exercise prescription training based on a progressive mode can significantly promote the recovery of lower limb motor function and physical fitness of elderly patients with lower limb dysfunction after deep burns, and effectively reduce the patient's risk of falling without causing adverse events during the training period, resulting in patient's high satisfaction with the training effect.

Objective:To observe the effect of progressive core muscle group training combined with lower limb intelligent rehabilitation training on burn patients with lower limb dysfunction.Methods:A prospective randomized controlled study was conducted. From March 2017 to May 2020, 60 patients with motor and balance dysfunction after deep partial-thickness burns or full-thickness burns of both lower extremities who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Military Medical University. They were divided into simple intelligent rehabilitation group (30 cases, 20 males and 10 females, aged (40±3) years) and combined rehabilitation group (30 cases, 16 males and 14 females, aged (39±3) years) according to the random number table method. The patients in both groups started red light treatment after the wound healing or when the scattered residual wound area was less than 5% total body surface area. After 2 weeks of red light treatment, patients in the combined rehabilitation group started progressive core muscle group training on the basis of lower limb intelligent rehabilitation training in simple intelligent rehabilitation group, and the training time was 6 weeks. Before and after 6 weeks of training, the lower limb motor function was evaluated with the simple Fugl-Meyer scale, the balance capacity was evaluated with the Berg balance scale, and the walking capacity was evaluated with the Holden walking ability rating scale. After 6 weeks of training, a self-designed questionnaire was used to investigate patients' satisfaction for the treatment effect. The patients were followed up for 6 months after the treatment to observe the balance stability of standing on one foot in the flexion position and their participation in activities of daily life. Data were statistically analyzed with independent sample t test, paired sample t test, and chi-square test. Results:Before training, the lower limb motor function score of patients in simple intelligent rehabilitation group was 24.9±2.7, which was close to 23.9±2.3 in combined rehabilitation group ( P>0.05). After 6 weeks of training, the lower limb motor function score of patients in combined rehabilitation group was 29.6±3.9, which was significantly higher than 27.3±3.8 in simple rehabilitation group ( t=-2.28, P<0.05). The lower limb motor function scores of patients in combined rehabilitation group and simple intelligent rehabilitation group after 6 weeks of training were significantly higher than those before training (with t values of -6.50 and -3.21, respectively, P<0.01). After 6 weeks of training, the balance capacity score of patients in combined rehabilitation group was 41±7, which was significantly higher than 36±5 in simple intelligent rehabilitation group ( t=-2.68, P<0.05); the balance capacity scores of patients in combined rehabilitation group and simple intelligent rehabilitation group after 6 weeks of training were significantly higher than those before training (with t values of -8.72 and -8.09, respectively, P<0.01). After 6 weeks of training, the walking capacity grading of patients in combined rehabilitation group was significantly improved compared with that in simple intelligent rehabilitation group ( χ2=-2.14, P<0.05), and the walking capacity grading of patients in simple intelligent rehabilitation group and combined rehabilitation group after 6 weeks of training was significantly improved compared with that before treatment (with χ2 values of -4.94 and -5.26, respectively, P<0.01). After 6 weeks of training, the satisfaction score for the treatment effect of patients in combined rehabilitation group was 13.7±1.2, which was significantly higher than 7.8±1.4 in simple intelligent rehabilitation group ( t=22.84, P<0.01). The patients in both groups could stand on one foot to maintain balance in the flexion position of lower limb, and their activities of daily life were not affected 6 months after treatment. Conclusions:On the basis of conventional rehabilitation therapy, the combination of progressive core muscle group training and lower limb intelligent rehabilitation training can significantly promote the recovery of lower limb motor and balance function of burn patients.

Objective:To construct and evaluate a parotid mass malignancy risk model based on ultrasound image characteristics and clinical features of parotid masses.Methods:Ultrasound images and clinical features of 214 patients with parotid masses in the First People′s Hospital of Foshan were retrospectively collected from June 2018 to August 2020. The pathology results were taken as the golden standard. All the clinical features and ultrasound image features were first screened using regression analysis, and then the screened features were used to build a prediction model.Results:Malignant tumors of the parotid gland appeared on ultrasound as hypoechoic solid masses with or without abnormal cervicofacial lymph nodes with poorly defined borders and irregular morphology. Multifactorial analysis showed that facial nerve function, cervicofacial lymph node abnormalities, maximum diameter, morphology and borders of the mass were independent predictors of the risk of malignant parotid masses. A Nomogram prediction model was established using the above 5 indicators, and the results showed a concordance index(C-index) of 0.896 (95% CI=0.834-0.958) for Nomogram. The standard curve showed good agreement between the predictive effect of Nomogram and the actual situation of benign and malignant parotid swellings, with an internally validated C-index of 0.878. Conclusions:Ultrasound is of great value in identifying benign and malignant parotid tumors. The Nomogram model using ultrasound image features and clinical characteristics can assess the biocharacteristics of parotid masses, and the model shows high accuracy in predicting the risk of malignancy of parotid masses.

Objective:
To observe the joint effect of school and family tobacco control on middle school students, and to explore its effectiveness in reducing second-hand smoke exposure in middle school students’ families, as so asto provide a new way of thinking for controlling smoking among middle school sudents.
Methods:
A questionnaire survey was conducted on the study of 2 125 primary and high school students in four middle schools in the Dongcheng District of Beijing by means of a stratified group sampling method. Personal information of students, tobacco control environment around the family, school and surrounding ares, as well as the knowledge, attitude and behavior of students related to tobacco control was collected.
Results:
The exposure rate of second-hand smoke in the families of middle and high school students in Dongcheng District of Beijing was 33.41%. Smoking by at least one parent was positively correlated with second-hand smoke exposure in the student’s home (OR=22.88, P<0.05). Among the students who saw the "clear no-smoking label" on campus, the exposure rate (4.92%) when the smoking restriction was set on the home was lower than that of those who did not have a regulation in the home (58.94%) (χ2=452.57, P<0.01). The results of Logistic regression showed that there was a combination of family smoking restrictions and second-hand smoke exposure in middle and high school students who had seen the smoking ban on campus (OR=0.08) and had the school’s tobacco control education (OR=0.08).
Conclusion
The joint tobacco control measures between school and family can effectively reduce the exposure rate of second-hand smoke in middle school students’ families, which is better than the effect of tobacco control alone.
