Objective:To summary the clinical and electrophysiological characteristics of temporal lobe epilepsy (TLE) originating from the temporal pole (TP), and to conduct brain network analysis based on stereo-electroencephalogram (SEEG) and head positron emission tomography- computed tomography (PET-CT).Methods:A retrospective analysis was conducted on patients with TLE who underwent SEEG implantation from January 1, 2019 to September 1, 2023 in Guangdong Sanjiu Brain Hospital. Based on anatomical-electrical-clinical analysis and SEEG findings, patients with seizures originating from the TP were selected. The clinical data, head magnetic resonance imaging (MRI), PET-CT, scalp electroencephalogram were reviewed, and the seizure-induced network was analyzed based on SEEG and head PET-CT.Results:A total of 108 cases of TLE were analyzed, of whom 13 cases had an epileptogenic zone located at the TP, accounting for 12% (13/108) of all TLE patients. Among them, 8 were males and 5 were females, and age of onset was (11.6±7.8) years. All of them were drug-resistant epilepsy patients, of whom 6 cases had normal cognitive function, 4 had mild cognitive abnormalities, and 3 had severe cognitive decline. A total of 59 seizures were recorded, and the occurrence rate of generalized tonic-clonic seizures (GTCS) was 42% (25/59). Seizure symptoms were classified into 3 types: the first type was hypermotor, seen in 9 patients; the second type was complex motor, seen in 2 patients; and the third type was automotor, seen in 2 patients. Head MRI showed that 9 cases had a blurring of the TP on one side, with or without hippocampal sclerosis; 2 cases had a mass at the TP without hippocampal sclerosis; 2 cases were negative on head MRI. Head PET-CT showed that 13 cases had TP hypometabolism on the lesion side, of whom 11 cases had hypometabolism involving the medial temporal lobe (mTL), posterior orbital gyrus (POG), anterior cingulate gyrus (ACG) and insular lobe at the same time, the other 2 cases combined with ipsilateral hypometabolism of the medial temporal lobe. Pathology showed that 7 cases had microcortical dysplasia of the TP; 3 had focal cortical dysplasia Ⅰ or focal cortical dysplasia Ⅱ; 2 had benign tumors. Scalp electroencephalogram showed that interictal phase was divided into 3 discharge patterns: bilateral temporal regions with prominent lesion side; bilateral anterior regions with prominent lesion side; lesion-side hemisphere with prominent temporal region. Ictal period showed 4 initial patterns: lesion-side hemispheric rhythmic spikes-slow waves or polyspikes-slow waves; lesion-side anterior region rhythmic slow waves; lesion-side anterior region low voltage fast (LVF) activities, and diffuse LVF with prominent lesion-side hemisphere. SEEG showed that 13 patients received electrode implantation with (9±2) electrodes per patient, divided into 3 seizure patterns: type 1: TP?adjacent temporal neocortex?POG, ACG and insula?mTL; type 2: TP?para hippocampal gyrus and the base of temporal lobe?ACG ,POG and insula?mTL; type 3: TP?mTL?insular lobe?POG.Conclusions:TLE originating from the TP is relatively rare, with hypermotor or complex motor as the main manifestations, and automotor being relatively less common, which is more likely to be followed by GTCS. The epileptogenic network analysis displays a tendency to spread from the TP to the frontal and insular lobes, as well as to the mTL, with the former pattern being more common. Common etiologies are cortical dysplasia and benign tumors of the TP without hippocampal sclerosis.

Objective:To explore the improvement of diaphragm function after early off-bed mobility intervention in intensive care unit (ICU) patients undergoing mechanical ventilation.Methods:A randomized controlled trial was conducted. A total of 147 adult patients undergoing mechanical ventilation admitted to ICU of Affiliated Hospital of Zunyi Medical University from October 2019 to March 2022 were enrolled. The patients were divided into control group and observation group by convenient sampling. Except for the different intervention programs of early mobility, other treatment and nursing of the patients in the two groups were carried out according to ICU routine. Progressive early activities were performed in the control group, while early off-bed mobility was performed in the observation group. The changes of diaphragm thickness at the end of inspiratory (DTei), diaphragm thickness at the end of expiratory (DTee) and diaphragm thickening fraction (DTF) before and 24, 48, 72 and 96 hours of intervention, and the duration of mechanical ventilation, length of ICU stay and 24-hour re-intubation rate after intervention were compared between the two groups.Results:Among the 147 patients, there were 4 cases of detachment in the control group and 5 cases of detachment in the observation group. Finally, 138 patients were enrolled, 69 cases in the control group and 69 cases in the observation group. There was no significant difference in gender, age, diagnosis of ICU, sedatives, muscle strength, ventilator model, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and DTei, DTee, DTF before intervention between the two groups. The DTei, DTee and DTF in both groups were increased gradually with the extension of intervention time, especially in the observation group [DTei (cm) at 24, 48, 72 and 96 hours of intervention in the observation group were 0.247±0.014, 0.275±0.016, 0.300±0.013 and 0.329±0.013, while in the control group were 0.242±0.015, 0.258±0.013, 0.269±0.014, and 0.290±0.017, effect of time: F = 993.825, P = 0.000, effect of intervention: F = 82.304, P = 0.000, interaction effect between intervention and time: F = 84.457, P = 0.000; DTee (cm) of the observation group were 0.213±0.014, 0.227±0.013, 0.243±0.016, 0.264±0.010, while in the control group were 0.213±0.016, 0.218±0.013, 0.224±0.013, 0.234±0.014, effect of time: F = 385.552, P = 0.000, effect of intervention: F = 28.161, P = 0.000, interaction effect between intervention and time: F = 45.012, P = 0.000; DTF of the observation group were (15.98±4.23)%, (21.35±4.67)%, (24.09±4.44)% and (25.24±3.74)%, while in the control group were (14.17±4.66)%, (18.11±3.92)%, (20.22±4.19)% and (20.98±4.12)%, effect of time: F = 161.552, P = 0.000, effect of intervention: F = 49.224, P = 0.000, interaction effect between intervention and time: F = -4.507, P = 0.000]. The duration of mechanical ventilation and length of ICU stay in the observation group were significantly shorter than those in the control group [duration of mechanical ventilation (hours): 112.68±12.25 vs. 135.32±22.10, length of ICU stay (days): 7.84±1.78 vs. 10.23±2.43, both P < 0.01]. However, there was no significant difference in 24-hour re-intubation rate between the observation group and the control group (0% vs. 2.90%, P > 0.05). Conclusions:Both early off-bed mobility and progressive early activities can prevent diaphragm weakness in ICU patients undergoing mechanical ventilation, and the effect of early off-bed mobility is better. Early off-bed mobility can significantly shorten the duration of mechanical ventilation and length of ICU stay, and it is safe and feasible.

ObjectiveTo investigate the effect of Bufeitang on intestinal flora of rats with lung Qi-deficiency syndrome of chronic obstructive pulmonary disease（COPD）， and to explore the mechanism of traditional Chinese medicine in regulating intestinal flora and thus restoring the balance of lung-gut axis. MethodA total of 84 rats were randomly divided into 7 groups， including blank group， model group， fecal bacterial transplantation（FMT） group， dexamethasone group and low， medium and high dose groups of Bufeitang， 12 rats in each group. Except for the blank group， cigarette and sawdust fumigation combined with intratracheal instillation of lipopolysaccharide（LPS） were used to establish the COPD rat model with lung Qi-deficiency syndrome in all other groups. The low， medium and high dose groups of Bufeitang were intragastric administrated with Bufeitang（3.645， 7.29， 14.58 g·kg^-1）， the FMT group was given fecal bacteria liquid enema（10 mL·kg^-1）， dexamethasone group was given dexamethasone acetate tablet suspension by gavage（0.135 mg·kg^-1）， the blank group and model group were given equal amount of distilled water. Fresh feces were collected after 28 d of continuous intervention for 16S rRNA gene sequencing. Lung and colon tissues were stained with hematoxylin-eosin（HE） for pathomorphological observation， and enzyme-linked immunosorbent assay （ELISA） was performed to detect the contents of tumor necrosis factor-α（TNF-α） and interleukin-8（IL-8） in lung tissues. ResultCompared with the blank group， the model group showed severe abnormal lung tissue structure with alveolar atrophy and collapse accompanied by severe inflammatory cell infiltration. Compared with the model group， the extent of injury was significantly improved， and inflammatory cell infiltration was reduced with basically normal alveolar structure in the high dose group of Bufeitang. Compared with the blank group， the model group had severely abnormal colonic tissue structure， the epithelial cells in the mucosal layer were eroded and shed， the number of inflammatory cells increased， the submucosal layer was edematous and the gap was enlarged. Compared with the model group， the extent of damage was significantly improved in the medium and high dose groups of Bufeitang， the epithelial cells in the mucosal layer were neatly and closely arranged， with only a small amount of inflammatory cell infiltration and no significant degeneration. Compared with the blank group， the TNF-α and IL-8 levels of lung tissue in the model group were significantly increased（P<0.01）. Compared with the model group， the TNF-α and IL-8 levels of lung tissues in the low， medium and high dose groups of Bufeitang were significantly decreased（P<0.01）. Bufeitang significantly modulated the number of bacteria species as well as alpha and beta diversity of model rats， corrected the return of intestinal flora to normal abundance and diversity， and positively regulated 4 differential phyla（such as Firmicutes， Proteobacteria） and 13 differential genera（such as Turicibacter， Lactobacillus， Anaerobiospirillum， Intestinimonas） in COPD model rats with lung Qi-deficiency syndrome， and down-regulated 2 carbohydrate metabolic pathway functions， including the pentose phosphate pathway（non-oxidative branch） Ⅰ and the Calvin-Benson-Bassham cycle. ConclusionBufeitang can modulate the abundance and diversity of intestinal flora species， affect the function of metabolic pathways， repair the structure of lung and colon tissues， regulate the level of inflammatory factors， and thus improve COPD with lung Qi-deficiency syndrome. The mechanism may be related to its regulation of inflammation-related intestinal flora to restore the balance of lung-gut axis in COPD with lung Qi-deficiency syndrome.

Objective:To retrieve and summarize evidence on non-pharmacological sleep management in adult critically ill patients, providing reference for sleep intervention by ICU medical and nursing staff.Methods:The literature on non-pharmacological sleep management in adult critically ill patients was systematically searched in domestic and foreign databases and guideline websites. The search period was from the establishment of the database to February 2023. After screening the literature based on inclusion and exclusion criteria, two evidence-based trained researchers independently evaluated the quality of the included literature, extracted and summarized evidence.Results:A total of 13 articles were included, including 3 clinical guidelines, 9 systematic reviews, and 1 randomized controlled trial. A total of 21 best pieces of evidence were summarized, covering 5 aspects, including strengthening nurse education and training, improving ward environment, reducing sleep interruption, selecting mechanical ventilation modes reasonably, and promoting physical and mental relaxation.Conclusions:The evidence summarized can provide reference for the development of non-pharmacological sleep management plans for adult critically ill patients. ICU medical and nursing staff should carefully apply evidence in clinical practice based on evidence, fully consider the human resources and actual situation of the department, and combine it with the needs of patients.

Objective    To explore the application value of machine learning models in predicting postoperative survival of patients with thoracic squamous esophageal cancer. Methods    The clinical data of 369 patients with thoracic esophageal squamous carcinoma who underwent radical esophageal cancer surgery at the Department of Thoracic Surgery of Northern Jiangsu People's Hospital from January 2014 to September 2015 were retrospectively analyzed. There were 279 (75.6%) males and 90 (24.4%) females aged 41-78 years. The patients were randomly divided into a training set (259 patients) and a test set (110 patients) with a ratio of 7 : 3. Variable screening was performed by selecting the best subset of features. Six machine learning models were constructed on this basis and validated in an independent test set. The  performance of the models' predictions was evaluated by area under the curve (AUC), accuracy and logarithmic loss, and the fit of the models was reflected by calibration curves. The best model was selected as the final model. Risk stratification was performed using X-tile, and survival analysis was performed using the Kaplan-Meier method with log-rank test. Results    The 5-year postoperative survival rate of the patients was 67.5%. All clinicopathological characteristics of patients between the two groups in the training and test sets were not statistically different (P>0.05). A total of seven variables, including hypertension, history of smoking, history of alcohol consumption, degree of tissue differentiation, pN stage, vascular invasion and nerve invasion, were included for modelling. The AUC values for each model in the independent test set were: decision tree (AUC=0.796), support vector machine (AUC=0.829), random forest (AUC=0.831), logistic regression (AUC=0.838), gradient boosting machine (AUC=0.846), and XGBoost (AUC=0.853). The XGBoost model was finally selected as the best model, and risk stratification was performed on the training and test sets. Patients in the training and test sets were divided into a low risk group, an intermediate risk group and a high risk group, respectively. In both data sets, the differences in surgical prognosis among three groups were statistically significant (P<0.001). Conclusion    Machine learning models have high value in predicting postoperative prognosis of thoracic squamous esophageal cancer. The XGBoost model outperforms common machine learning methods in predicting 5-year survival of patients with thoracic squamous esophageal cancer, and it has high utility and reliability.

Objective: In this study, black tea and Citrus maxima (BT-CM), yellow tea and C. maxima (YT-CM), green tea and C. maxima (GT-CM) as subjects, the active ingredient content and antioxidant activity of three tea and C. maxima (T-CM) were analyzed. The effects of three T-CMs on apoptosis of liver cells in vitro and its mechanism were further explored. Methods: National standard method and HPLC were used for active ingredient analysis. MTT, cell flow cytometry and Western blot were used to analyze the effects of three T-CMs on cell proliferation, apoptosis, and its underlying molecular mechanism. Results: The content of tea polyphenols, free amino acids, ratio of polyphenols and amino acids, ester catechins, non-ester catechins and caffeine in YT-CM and GT-CM was significantly higher than that of BT-CM. The in vitro antioxidant capacity of YT-CM and GT-CM was also significantly stronger than that of BT-CM. Three T-CMs had the effects of inhibiting proliferation, arresting cell cycle and inducing apoptosis in HepG2 and Bel7402 cells, especially YT-CM and GT-CM. Western blot analysis showed three T-CMs activated PI3K/AKT/mTOR signaling pathway and regulated the expression levels of apoptosis-related proteins Bax, Bcl-2 and Caspase-3/9. YT-CM and GT-CM had better ability to change the signal pathway than BT-CM. Conclusion: In short, T-CMs, which combined different degrees of fermentation tea with C. maxima, were rich in nutrients and biologically active substances. T-CMs, especially YT-CM and GT-CM, are healthy drinks that help to prevent and treat liver cancer.

Objective:To investigate the clinical features and influencing factors of early-onset gout.Methods:Male patients with gout admitted to Department of Endocrinology and Metabolism were recruited from 2015 to 2018. Patients with gout onset before age 30 were defined as the " early-onset" group, and those with onset at 30~60 years were defined as the "late-onset" group. Clinical characteristics were compared between two groups. Factors associated with early-onset gout were analyzed.Results:A total of 1 243 male patients were enrolled in this study; 480 individuals were in the early-onset, and 763 in the late-onset groups. Compared with the late-onset group, patients with early-onset gout had higher consumption rates of sugar-sweetened beverage(28.0% vs 15.0%, P=0.001), a higher homeostasis model assessment for insulin resistance level(3.78±2.93 vs 3.10±2.39, P<0.01), and larger proportions of family histories of diabetes(30.8% vs 20.4%, P<0.01)and hypertension(51.2% vs 42.6%, P=0.003). Logistic regression analysis showed that factors associated with early-onset gout were drinking sugar-sweetened beverage( P=0.012), family history of diabetes( P=0.037). Conclusion:Early-onset gout was associated with a family history of diabetes. Patients with family histories of diabetes are more likely to have early-onset gout, which may be associated with a common genetic basis.

Objective To evaluate the clinical efficacy of acupuncture on sphenopalatine ganglion in the treatment of severe perennial allergic rhinitis (PAR) in a randomized controlled clinical trials. Methods A total of 81 patients with severe perennial allergic rhinitis were randomly divided into three groups: 27 in the observation group, 27 in the drug control group and 27 in the acupuncture control group. The patients in the observation group were treated with acupuncture on sphenopalatine ganglion; and the patients in the drug control group took Desloratadine; and the patient in the acupuncture control group were treated with acupuncture on Yintang (GV 29) and Yingxiang (LI 20). All the groups were treated for 4 weeks. The TNNS and VAS score system were tested before and after the treatment, and the nasal exhalation of nitric oxide (eNO) concentration level wa detected at baseline and each week's during treatments. Results After the treatment,the effective rate [80.8%(21/26)vs.64.0%(16/25),65.4%(17/26),x2=13.811]of the observation group was significantly higher than either the drug control group or the acupuncture control group (P<0.01). Compared to the score of the three group before treatment, the TNNS score was significantly lower (P<0.01) after the treatment. Compared with the drug control group, the level of eNO in nasal exhalation air (265.377 ± 36.475 ppb vs. 281.769 ±45.823 ppb vs. 295.231 ± 24.595 ppb, F=4.247) of the observation group and the acupuncture control group were significantly higher (P<0.05). Conclusions Acupuncture on the sphenopalatine ganglion can not reduce the eNO concentration level of nasal exhaled air in patients with perennial allergic rhinitis, but it can improve the symptoms of rhinitis. The clinical effect of acupuncture on the sphenopalatine ganglion was better than the desloratadine and acupuncture on GV 29 and LI 20.

A simple and effective high-performance liquid chromatography with diode-array detection method coupled with a liquid-liquid extraction pretreatment has been developed for determining the pharmacokinetics and tissue distribution of a novel structurally modified derivative (8-acetamino-isocorydine) of isocorydine. According to the in vivo experiments data calculations by DAS 2.0 software, a two-compartment metabolic model was suitable for describing the pharmacokinetic of 8-acetamino-isocorydine in rats. 8-Acetamino-isocorydine was absorbed well after oral administration, and the absolute bioavailability was 76.5%. The half-life of 8-acetamino-isocorydine after intravenous and oral administration was 2.2 h and 2.0 h, respectively. In vivo, 8-acetamino-isocorydine was highly distributed in the lungs, kidney and liver; however, relatively little entered the brain, suggesting that 8-acetamino-isocorydine could not easily pass through the blood brain barrier. Our work describes the first characterization of the pharmacokinetic parameters and tissue distribution of 8-acetamino-isocorydine. The acquired data will provide useful information for the in vivo pharmacology of 8-acetamino-isocorydine, and can be applied to new drug research.

Objective To investigate the expression and correlation of cell cycle protein-D1 and Ki-67 in laryngeal cancer tis-sues.Methods Immunohistochemical streptavidin-perosidase ( SP) staining method was used to detect the expression of Cyclin D 1 and Ki-67 proteins in laryngeal squamous cell carcinoma tissues and their correlation between Cyclin D 1 and Ki-67 was analyzed .Re-sults Among 56 cases of Cyclin D1 positive over-expressed laryngeal squamous cell carcinoma tissues , 41 cases of Ki-67 had positive over-expression.Among 51 cases of Ki-67 low-expressed tissues, 35 cases of Cyclin D1 had low-expression.Spearman rank correlation test showed that expressions of Cyclin D 1 and Ki-67 in laryngeal squamous cell carcinoma tissues had a significant positive correlation ( rs =0.620, P <0.01).Conclusions Cyclin D1 and Ki-67 expressions in laryngeal squamous cell carcinoma have a significantly positive correlation .
