Objective: To explore the latent categories and general demographic characteristics of short form video addiction among college students, so as to provide empirical reference for prevention and intervention of short form video addiction among college students. Methods: Convenience sampling method was used to select 1 386 college students from a certain university in Anhui Province in June 2023. A questionnaire survey was conducted among college students by using the Short Video Addiction Scale. The latent profile analysis method of "individual center" was used to explore the categories of college students short form video addiction, and multiple Logistic regression was used to explore the influence of demographic variables on the latent classification of short form video addiction. Results: College students with short form video addiction were divided into three latent categories:non addiction group (22.15%, n =307), low addiction group (63.28%, n =877) and high addiction group (14.57%, n =202). The results of multiple Logistic regression analysis showed that gender, major type and family location were related with short form video addiction among college students:male students (low addiction group: OR =0.47; high addiction group: OR =0.41), cultural and historical majors (low addiction group: OR =0.66), and students from cities (high addiction group: OR =0.51) were less likely to be involved in short form video addiction ( P <0.05). Conclusions There is significant group heterogeneity in short form video addiction among college students. Families, schools and society should attach importance and pay attention to the phenomenon of short form video addiction among college students, actively take targeted intervention measures to prevent and reduce the occurrence of short form video addiction symptoms among college students.

Objective:To investigate the effect of sodium tanshinone ⅡA sulfonate (STS) on pyroptosis of human umbilical vein endothelial cells (HUVECs) induced by H 2O 2 and its possible mechanism. Methods:From November 2021 to September 2022, HUVECs were used as the research subjects at Wuxi Ninth People’s Hospital. The experiment was divided into four groups: the blank control group (normal condition), blank + STS group, H 2O 2 group and H 2O 2 + STS group. When the cells reached 80% fusion, 500.00 μmol/L of H 2O 2 was added to H 2O 2 group and H 2O 2 + STS group for 3 hours, and then the medium containing 500.00 μmol/L H 2O 2 was removed. After that, the blank+ STS group and the H 2O 2+ STS group were each supplemented with 5.00 μg/ml of STS and co-cultured with HUVECs for 24 hours. CCK-8 was used to assess the impact of STS at various concentrations (0.00, 0.05, 0.50, 5.00, 50.00, 500.00 μg/ml) on the proliferation of HUVECs. DNA damage-positive cells were detected with TUNEL staining. The expression of NOD-like receptor protein 3 (NLRP3) was detected using real-time PCR (RT-PCR) to investigate the optimal concentration of pyroptosis induced by H 2O 2. A detection kit was used to measure the expression of reactive oxygen species (ROS) induced by H 2O 2. The effect of STS on the migration and tube formation of HUVECs during pyroptosis was examined using a cell scratch test and a matrix gel tube formation test. The expressions of NLRP3, caspase-1, interleukin-18, and interleukin-1β were detected using RT-PCR and Western blotting. Repeated measures ANOVA was used to compare the concentrations at different time points, t-tests were used to compare data between two groups, and one-way ANOVA was used to compare data between multiple groups. P<0.05 was considered statistically significant. Results:STS below 50.00 μg/ml had no effect on the proliferation of HUVECs, while 500.00 μmol/L H 2O 2 had the most significant effect on inducing pyroptosis in HUVECs. TUNEL staining showed that compared with the control group, the number of TUNEL-positive cells in H 2O 2 group was significantly increased, and the difference was statistically significant ( P<0.01). However, there was no significant difference in the number of TUNEL-positive cells in the H 2O 2+ STS group ( P>0.05). The results of ROS detection showed that compared with the H 2O 2 group, intracellular ROS levels in the H 2O 2+ STS group was significantly decreased, and the difference was statistically significant ( P<0.01). Cell scratch and tube formation in vitro experiments showed that compared with the control group, cell mobility and tube formation ability were significantly decreased in the H 2O 2 group (all P<0.01), and there was no statistical significance in the H 2O 2+ STS group (all P>0.05). RT-PCR and Western blotting results showed that, compared with the H 2O 2 group, the expression of pyroptosis-related factors in the H 2O 2+ STS group was significantly decreased (all P<0.05). Conclusion:STS can inhibit the excessive production of ROS, promote the cell migration and tubular formation of HUVECs after pyroptosis induction, and alleviate H 2O 2-induced pyroptosis of HUVECs, thereby promoting angiogenesis.

Objective:To observe the clinical phenotype of patients with CACNA1F gene variant. Methods:A retrospective clinical study. From January 1, 2022 to October 1, 2023, 36 patients with CACNA1F gene mutation-related eye diseases diagnosed by clinical examination and genetic testing in Changsha Aier Eye Hospital and Jinan Purui Eye Hospital were included in the study. All patients underwent best-corrected visual acuity (BCVA), medical optometry, fundus color photography, optical coherence tomography, full-field electroretinography (ERG), nystagmus examination, and genetic whole-exon sequencing. BCVA was performed using log visual acuity charts and converted to (logMAR). The nystagmus examination was performed using a helmet-mounted multifunctional video eye movement recording system. The clinical phenotypic characteristics were observed. Results:At total of 36 patients were male, aged was (6.69±5.26) years. There were 36 cases of myopia (38.89%, 14/36), and the spherical equivalent was (?3.01±4.84) D. There were 14 different genetic variants including 7 cases of pathogenic variants, 20 cases of suspected pathogenic variants and 9 cases of unknown pathogenic variants, respectively. logMAR BCVA was 0.67±0.27; 26 patients had optic nerve atrophy (72.22%, 26/36); 6 had optical nerve hypoplasia (16.67%, 6/36). Fundus pigment dysplasia with mild iris transillumination was found in 4 cases (11.11%, 4/36). There were 5 cases of foveal dysplasia (Thomas grade) 1 (13.89%, 5/36). In full-field ERG examination, the B-wave reduction of the maximum mixed reaction of dark adaptation showed a negative waveform, and the amplitude of the shock potential was seriously reduced. The main phenotypes were residual type (residual dark adaptation 0.01 reaction wave and bright adaptation 3.0 reaction wave, and the response decreased at 30 Hz to a double-peak wide wave), dominant type of bright adaptation decreased (all light adaptation extinguished, all dark adaptation extinguished), and total extinction type (all light adaptation extinguished). Among them, 10 cases presented with residual ERG (27.78%, 10/36), 8 cases with photopic reduced ERG (22.22%, 8/36) and 18 with extinguished ERG (50.00%, 18/36). Low amplitude and high frequency pendulum (PLAHF) nystagmus waverforms were found in 32 cases (88.89%, 32/36), head oscillation in 27 cases (75.00%, 27/36) and chin up abnormal head posture in 26 cases (72.22%, 26/36), respectively.Conclusions:CACNA1F Gene variant eye diseases had diverse clinical phenotype. Clinical phenotype of PLAHF nystagmus is closely related with CACNA1F gene variant eye disease.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Objective To investigate the clinical diagnostic value of anti-cyclic citrullinated peptide(CCP)antibody,anti-mutated citrullinated vimentin(MCV)antibody and 25-hydroxyvitamin D[25-(OH)D]in rheumatoid arthritis(RA)patients.Methods A total of 466 patients with RA who were admitted the Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from August 2016 to November 2021 were included in RA group,100 patients with other autoimmune diseases and metabolic diseases without RA were included in non-RA group,100 healthy subjects were included in control group.Serum anti-CCP antibody,anti-MCV antibody and 25(OH)D were detected in three groups.Receiver operating characteristic curve was drawn to analyze the diagnostic efficacy of anti-CCP antibody,anti-MCV antibody and 25(OH)D in RA.The correlation between anti-MCV antibody and clinical indexes in RA patients was analyzed.Results Serum anti-MCV antibody and anti-CCP antibody in RA group were significantly higher than those in non-RA group and control group(P<0.05).The serum 25(OH)D level in RA group was significantly lower than that in control group(P<0.05).The area under the curve(AUC)of anti-CCP antibody,anti-MCV antibody and 25(OH)D for the diagnosis of RA were 0.74,0.81 and 0.75,respectively.The AUC for the combined diagnosis of RA was 0.90,the sensitivity was 83.70%,and the specificity was 82.40%.Anti-MCV antibody was positively correlated with erythrocyte sedimentation rate and C-reactive proten(r=0.66,0.64,P<0.05),and negatively correlated with complement C3 and C4(r=-0.69,-0.62,P<0.05).Conclusion Anti-CCP antibody,anti-MCV antibody and 25(OH)D have good sensitivity and specificity for the diagnosis of RA,and anti-MCV antibody was helpful for the diagnosis of the disease activity.

We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia (GTN). In this trial (NCT01823315), 276 patients were analyzed. Patients were allocated to three initiated regimens: single-course methotrexate (MTX), single-course MTX + dactinomycin (ACTD), and multi-course MTX (control arm). The primary endpoint was the complete remission (CR) rate by initial drug(s). The primary CR rate was 64.4% with multi-course MTX in the control arm. For the single-course MTX arm, the CR rate was 35.8% by one course; it increased to 59.3% after subsequent multi-course MTX, with non-inferiority to the control (difference -5.1%,95% confidence interval (CI) -19.4% to 9.2%, P = 0.014). After further treatment with multi-course ACTD, the CR rate (93.3%) was similar to that of the control (95.2%, P = 0.577). For the single-course MTX + ACTD arm, the CR rate was 46.7% by one course, which increased to 89.1% after subsequent multi-course, with non-inferiority (difference 24.7%, 95% CI 12.8%-36.6%, P < 0.001) to the control. It was similar to the CR rate by MTX and further ACTD in the control arm (89.1% vs. 95.2%, P =0.135). Four patients experienced recurrence, with no death, during the 2-year follow-up. We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN.

Objective:To study the clinical, endoscopic and histological characteristics of heterotopic gastric mucosa in upper esophagus (HGMUE).Methods:A Total of 177 patients who underwent gastroscopy and were diagnosed as having HGMUE at the Endoscopy Center of Wuhan Union Hospital from January 2017 to December 2017 were included in the study. According to the gastroesophageal reflux disease symptom questionnaire (GERD-Q) scores, patients were divided into the HGMUE group (GERD-Q<8, n=101) and GERD+HGMUE group (GERD-Q≥8, n=76). The data of clinical, endoscopic and histological characteristics were analyzed. Results:Among the 177 HGMUE cases, there were 111 males (62.71%) and 66 females (37.29%), 76 (42.94%) with GERD, and 101 (57.06%) without GERD. The most common symptom was continuous clearing throat [54.24% (96/177)], followed by foreign body sensations of throat [48.59% (86/177)], and gastroesophageal reflux symptoms such as heartburn, chest pain, indigestion, acid reflux [48.59% (86/177)]. In the HGMUE group, the occurrence rate of clearing throat was the highest [42.57% (43/101)], then foreign body sensations of throat accounted for 33.66% (34/101), and gastroesophageal reflux symptoms was 27.72% (28/101). In the HGUME+GERD group, the most common symptom was gastroesophageal reflux symptoms [76.32% (58/76)], then clearing throat [69.74% (53/76)] and foreign body sensations of throat [68.42% (52/76)]. Under gastroscopy, 177 heterotopic gastric lesions were found under gastroscopy with orange-red round, oval or elongated island like ones, most of which were flat and a few slightly protruded from the peripheral plane. There were 132 (74.58%) single-lesion cases, 38 (21.47%) 2-lesion, and 7 (3.95%) 3- or more-lesion cases; there were 37 (20.90%) small lesions (maximum diameter <0.5 cm), and 74 (41.81%) median-size lesions (maximum diameter of 0.5-1.0 cm), and 66 (37.3%) larger lesions (maximum diameter >1.0 cm). Among the 30 [16.95% (30/177)] samples of mucosal tissue, 15 [50.00% (15/30)] were mainly cardia gland, 8 [26.67% (8/30)] were mainly pyloric gland, 6 [20.00% (6/30)] were mixed type, and 1 [3.33% (1/30)] was squamous epithelium. In the immunohistochemical test, 20 cases [66.67% (20/30)] showed positive of H +/K +-ATPase, and 10 cases [33.33% (10/30)] were negative. Conclusion:HGMUE is more common in male patients, and may be combined with GERD. Among them, patients with combined GERD are more likely to develop laryngopharyngeal reflux. The heterotopic gastric mucosas lesions are orange-red round, oval or elongated island-like under gastroscopy, and most of them are flat, single and median- or large-sized. Histological types are mostly fundic glands, and H +/K +-ATPase positive is more common. It is speculated that acid secretion may be an important factor leading to throat symptoms.

Objective:To investigate the clinical effects of intermittent oro-esophageal tube feeding (IOE) combined with Xuanqiaoliyan decotion in stroke patients with dysphagia.Methods:A prospective study was conducted. Stroke patients with dysphagia admitted to Yidu Central Hospital Affiliated Hospital of Weifang Medical University from January 2018 to December 2019 were enrolled. According to the simple random sampling method, the patients were divided into control group and observation group, with 50 cases in each group. The control group was given routine swallowing function training, including low-frequency pulse electrical stimulation, swallowing function training and acupuncture treatment. The observation group was given IOE and Xuanqiaoliyan decoction (prescription composition: Rhizoma acori tatarinowii 15 g, Radix polygalae 10 g, Rhizoma gastrodiae 15 g, Arisaema cum bile 6 g, Rhizoma typhonii 6 g, Scorpio 6 g, Bombyx batryticatus 6 g, Perilla frutescens 10 g, Rhizoma pinelliae 10 g, Pericarpium citri reticulatae 10 g, Rhizoma zingiberis recens 3 tablets, decoction 200 mL, twice in the morning and evening by oral or nasal feeding) on the basis of the control group. Both groups were treated for 14 days. The standard swallowing function assessment (SSA) and water swallow test were used to evaluate the swallowing function before and after treatment. The time required for the improvement of swallowing function, total hospitalization time and the therapeutic effects were observed and the safety assessment was conducted. Results:There were no significant differences in the gender, age, course of disease, and location and frequency of stroke between the two groups. After treatment, both the SSA scores in the two groups were decreased, and the grading of water swallow test was improved. The SSA scores in the observation group were significantly lower than that in the control group (19.8±1.8 vs. 23.2±3.2, P < 0.05), the recovery degree of water swallow test was higher than that in the control group [complete recovery (cases): 18 vs. 13, basic recovery (cases): 23 vs. 18, effective (cases): 9 vs. 19, χ 2 = -2.107, P = 0.008]. The total effective rate of swallowing function in the observation group was higher than that in the control group (94.0% vs. 80.0%, Z = 4.684, P = 0.012), the time for improvement (days: 12.8±2.6 vs. 16.9±4.3, t = 11.628, P = 0.008) and total hospitalization time (days: 20.8±4.2 vs. 33.5±5.6, t = 10.924, P = 0.015) were shorter than those in the control group. In the observation group, there was 1 case of throat discomfort during the operation of IOE, and the symptoms disappeared after the operation; there was 1 case of mild elevation of alanine aminotransferase (ALT) and blood urea nitrogen (BUN) respectively, which returned to normal after the treatment. No adverse symptoms and damage to the liver and kidney were observed in the control group. Conclusion:IOE combined with Xuanqiaoliyan decotion could significantly improve the swallowing function of stroke patients with dysphagia, shorten the hospitalization time, and improve the curative effects and lifequality.
