Objective To investigate the effects of tegafur, gimeracil and oteracil potassium combined with oxaliplatin on gastric motility-related hormones, matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in elderly patients with gastric cancer. Methods A total of 128 elderly patients with gastric cancer were selected as the study subjects and randomly divided into control group (n=64) and observation group (n=64). The control group was treated with tegafur, gimeracil and oteracil potassium, while the observation group received tegafur, gimeracil and oteracil potassium combined with oxaliplatin. Gastric motility-related hormones [motilin (MTL) and vasoactive intestinal peptide (VIP)], MMP-2, MMP-9, tumor markers [carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125) and carbohydrate antigen 19-9 (CA19-9)], clinical efficacy and occurrence of adverse reactions were observed in both groups. The correlations of gastric motility-related hormones with the levels of MMP-2, MMP-9 and tumor markers were analyzed. Results After treatment, MTL levels in both groups were significantly lower, while VIP levels were significantly higher compared to before treatment. Additionally, the observation group had significantly lower MTL and higher VIP levels compared to the control group (P < 0.05). After treatment, the levels of MMP-2, MMP-9, CEA, CA125 and CA19-9 were significantly reduced in both groups compared to pretreatment levels, with the observation group showing significantly lower levels than the control group (P < 0.05). The total effective rate in the observation group was 70.31%, which was significantly higher than the 53.13% in the control group (P < 0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (P>0.05). A negative correlation was observed between MTL and MMP-2, MMP-9, CEA, CA125 as well as CA19-9 (P < 0.05), while VIP showed a positive correlation with MMP-2, MMP-9, CEA, CA125 and CA19-9 (P < 0.05). Conclusion The combination of tegafur, gimeracil and oteracil potassium and oxaliplatin is effective and safe for the treatment of elderly patients with gastric cancer. MTL, VIP, MMP-2, MMP-9, CEA, CA125 and CA19-9 are interrelated in the development of gastric cancer in elderly patients.

Objective To analyze the effect of nursing interventions based on the Information-Motivation-Behavioral Skills (IMB) model in patients with functional dyspepsia, in order to improve their psychological state and gastrointestinal motility, and provide reference for clinical nursing. Methods A total of 160 functional dyspepsia patients admitted to the First Affiliated Hospital of Xinxiang Medical College from December 2022 to June 2023 were chosen as the study subjects. They were randomly divided into control group and observation group, using a random number table method, with 80 cases in each group. Patients in control group were given routine nursing intervention, and patients in the observation group were treated nursing intervention based on IMB model. The psychological state, gastrointestinal motility andquality of life of the two groups were compared before and after intezrvention. Results After intervention, the scores of Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) in two groups were decreased, and the observation group was lower than that in the control group (P < 0.05). After intervention, the levels of gastrointestinal hormone nitric oxide (NO), serum motilin (MTL) andserum gastrin (GAS) in two groups were improved, and the levels of all indexes in the observation group were better than those in the control group (P < 0.05). After intervention, gastrointestinal quality of life index (GIQLI) of two groups was improved, and the observation group was higher than the control group, the difference was statistically significant (P < 0.05). Conclusion Nursing interventions based on the IMB model are beneficial for alleviating anxiety and depression in patients with functional dyspepsia, effectively enhancing gastrointestinal motility and vitality, and improving their quality of life.

Objectives:To evaluate the clinical value of the Paris system for reporting urinary cytology (TPS) in the diagnosis of urothelial carcinoma (UC).Methods:A total of 1 744 cytological diagnostic records (from 751 cases) were collected retrospectively. All specimens were voided urines and histopathology as the gold standard. The sensitivity and specificity of urinary cytological diagnosis of UC and risk of high grade malignant (ROHM) in each diagnostic category were compared.Results:There were 360 cases with histopathology. The percentage of negative for high-grade urothelial carcinoma (NHGUC) was 30.1% (226/751), atypical urothelial cells (AUC) was 29.8% (224/751), suspicious for high-grade urothelial carcinoma (SHGUC) was 16.8% (126/751), high grade urothelial carcinoma (HGUC) was 21.2% (159/751), and non-urothelial malignancy (NUM) was 2.1% (16/751). The histpathologic ROHM corresponding to each cytological diagnosis category were 27.3% for NHGUC, 32.7% for AUC, 74.7% for SHGUC, 96.6% for HGUC and 100.0% for NUM, respectively. ROHM of SHGUC was significantly higher than that of AUC group, and the difference between the two groups was statistically significant ( P＜0.001). ROHM of HGUC group was significantly higher than that of SHGUC group, and the difference was statistically significant ( P＜0.001). With SHGUC as the cut-off value, the sensitivity and specificity of cytological diagnosis of HGUC were 76.7% (165/215) and 85.7% (18/21), and with HGUC as the cut-off value, the sensitivity and specificity of cytological diagnosis of HGUC were 53.0% (114/215) and 100.0% (21/21), respectively. Conclusions:Urine cytology has high sensitivity and specificity in the diagnosis of HGUC. The malignant risk of TPS varies with different diagnosis category. The high malignant risk population in cancer hospital leads to the relatively high malignant proportion and ROHM in each diagnosis category. Urinary cytology TPS reporting system is helpful to clinical management and has good clinical application value.

Objective: To explore the clinical and genetic characteristics of children with dopa-responsive dystonia (DRD) caused by tyrosine hydroxylase (TH) gene variations. Methods: Clinical data of 9 children with DRD caused by TH gene variations diagnosed in the Department of Children Rehabilitation, the Third Affiliated Hospital of Zhengzhou University from January 2017 to August 2022 were retrospectively collected and analyzed, including the general conditions, clinical manifestations, laboratory tests, gene variations and follow-up data. Results: Of the 9 children with DRD caused by TH gene variations, 3 were males and 6 were females. The age at diagnosis was 12.0 (8.0, 15.0) months. The initial symptoms of the 8 severe patients were motor delay or degression. Clinical symptoms of the severe patients included motor delay (8 cases), truncal hypotonia (8 cases), limb muscle hypotonia (7 cases), hypokinesia (6 cases), decreased facial expression (4 cases), tremor (3 cases), limb dystonia (3 cases), diurnal fluctuation (2 cases), ptosis (2 cases), limb muscle hypertonia (1 case) and drooling (1 case). The initial symptom of the very severe patient was motor delay. Clinical symptoms of the very severe patient included motor delay, truncal hypotonia, oculogyric crises, status dystonicus, hypokinesia, decreased facial expression, and decreased sleep. Eleven TH gene variants were found, including 5 missense variants, 3 splice site variants, 2 nonsense variants, and 1 insertion variant, as well as 2 novel variants (c.941C>A (p.T314K), c.316_317insCGT (p.F106delinsSF)). Nine patients were followed up for 40 (29, 43) months, and no one was lost to follow-up. Seven of the 8 severe patients were treated by levodopa and benserazide hydrochloride tablets and 1 severe patient was treated by levodopa tablets. All the severe patients responded well to levodopa and benserazide hydrochloride tablets or levodopa tablets. Although the weight of the patients increased and the drug dosage was not increased, the curative effect remained stable and there was no obvious adverse reaction. One severe patient developed dyskinesia in the early stage of treatment with levodopa and benserazide hydrochloride tablets and it disappeared after oral administration of benzhexol hydrochloride tablets. Until the last follow-up, motor development of 7 severe patients returned to normal and 1 severe patient still had motor delay due to receiving levodopa and benserazide hydrochloride tablets for only 2 months. The very severe patient was extremely sensitive to levodopa and benserazide hydrochloride tablets and no improvement was observed in this patient. Conclusions: Most of the DRD caused by TH gene variations are severe form. The clinical manifestations are varied and easily misdiagnosed. Patients of the severe patients responded well to levodopa and benserazide hydrochloride tablets or levodopa tablets, and it takes a long time before full effects of treatment become established. Long-term effect is stable without increasing the drug dosage, and no obvious side effect is observed.

Objective: To explore latent classes of college students aggressive behavior and its correlations with family care and the meaning of life among college students. Methods: A cross sectional questionnaire survey was conducted among 5 094 students from three universities in Xinxiang City in December 2021, using Aggression Questionnaire (AQ), Family APGAR Index (APGAR), and the Meaning in Life Questionnaire (MLQ). Results: Aggressive behavior of college students was classifed into three potential categories:low aggressive behavior group (26.4%), moderate aggressive behavior group (48.5%), and high aggressive behavior group(25.1%). There were significant differences in latent classes of aggressive behavior among college students by gender, physical flexibility, exercise frequency, and sleep status ( χ 2=63.95, 169.86, 125.76, 325.24, P <0.01). There were significant differences in the sense of life meaning and the degree of family care among the 3 potential categories of aggressive behavior ( F=113.47, 231.82, P <0.01). The multivariate Logistic regression analysis showed that the sense of meaning of life ( OR =0.96, 95% CI =0.96-0.97) and family care ( OR =0.83, 95% CI =0.81-0.84) were significantly associated with three classes of aggressive behavior ( P <0.01). Conclusion Aggressive behavior among college students is associated with gender, exercise frequency, sleep status, meaning of life, family care, and physical flexibility. School, family and society should actively pay attention to students psychological characteristics and to provide corresponding support for aggressive behavior prevention and intervention.

Objective To investigate the effect of fibroblast growth factor (FGF) on the proliferation and transdifferentiation of cardiac fibroblasts ( CFs ) into myofibroblasts ( MFs ). Methods Rat CFs were isolated and cultured, and then induced by FGF. CCK-8 was used to detect the cell activity and proliferation. Immunofluorescence and Western blotting were used to detect the expression of a smooth muscle actin ( α-SMA ) and collagen I ( Col I ). Results The expression and activation of α-SMA and Col I increased with the increase of CFs culture generation. The number of CFs induced by FGF did not increased significantly; the expression of α-SMA in CFs induced by FGF1 and FGF2 decreased, and the number of activated MFs decreased. Conclusion FGF family has no effect on the proliferation of CFs, but FGF1 and FGF2 can inhibit the activation of CFs and reduce the differentiation into MFs.

Objective: To investigats the specific changes of brain neuron oscillation in non-clinical high-trait anxiety college students by recording the resting state EEG of high and low trait anxiety subjects. Methods: College students in a university were administered by using the S-TA Inventory, 27% of the number of people before and after the selection were divided into low-specific focus group (15) and high-trait anxiety group(15), based on the STAT score. After pre-processing, the data was divided into five frequency bands of δ(1-<4), θ(4-<8), α(8-<13), β(13-<30), γ(30-100)Hz and every electrode power value of those was calculated respectively. Correlation between power spectrum and trait anxiety scores was investigated. Results: The high-trait anxiety group were in the frontal and central regions (t=3.47, 2.62) of the δ band, the frontal region (t=2.22) of the θ band, the frontal, central, right temporal, and posterior regions (t=2.77, 2.23, 3.65, 2.35) of the β band, the frontal, left temporal, central, right temporal, and posterior regions (t=2.83, 2.22, 2.64, 2.43, 2.09) of the γ band, than that in the low trait anxiety group. Furthermore, in central regions of the δ band; the frontal region of the θ band; the frontal, the central, and posterior regions of the β band; the frontal, left temporal, central, and posterior regions(r=-0.63, -0.51, -0.62, -0.53, -0.54, -0.59, -0.56, -0.55, -0.49) of the γ band, the correlation between trait anxiety scores and the power value were obvious negatively. Conclusion High trait anxiety college students have lower power spectrum than low trait anxiety college students. The degree of trait anxiety is related to the power spectrum. The changes of brain resting-state electrical signals in high-trait anxiety individuals may be related to the influence of trait anxiety on college students’ attention and working memory.
