Objective:To explore the differences in sociodemographic and clinical characteristics between pa-tients with unipolar depression bipolar depression and to establish a nomogram for identifying bipolar depression.Methods:Using data from the China Mental Disorders Cohort Study,the sociodemographic and clinical characteristics of 2 643 patients with unipolar depression and 250 patients with bipolar depression diagnosed accord-ing to the criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)were includ-ed to compare their sociodemographic and clinical characteristics.These characteristics included general demograph-ic information,disease-related information,clinical examination results,and the severity of the disease assessed with the Global Assessment of Functioning(GAF)and Hamilton Depression Rating Scale.Logistic regression analysis was employed to identify factors influencing bipolar depression,and a nomogram was constructed for its identifica-tion.Results:The risk factors for bipolar depression included being male(OR=1.48),being employed(OR=1.38),having non-melancholic features during episodes(OR=2.33),a Body Mass Index ranging from normal to obese(OR=2.48,2.49,4.65),psychotic features(OR=2.14),mixed episode(OR=9.36),comorbid physical diseases(OR=2.47),four or more depressive episodes(OR=1.67),earlier age of onset(OR=0.95),longer ill-ness duration(OR=1.03),and higher GAF scores(OR=1.02).The nomogram model achieved an AUC of 0.81(95％CI:0.78-0.84).The Hosmer-Lemeshow test result was x2=6.96(P＞0.05),indicating good model fit.The calibration curve showed good performance.The decision curve analysis revealed that the nomogram pro-vides significant clinical benefit when the risk of bipolar depression was within the range of 0 to 0.9.Conclusion:The nomogram established based on the identified sociodemographic and clinical factors can accurately assess the risk of bipolar depression,providing a useful tool for early identification and intervention.

Objective:To observe any effect of combining interactive scalp acupuncture with constraint-induced movement therapy (CIMT) in treating the upper extremity motor function of children with spastic hemiplegic cerebral palsy.Methods:Fifty-seven children with spastic hemiplegic cerebral palsy were randomly divided into a control group of 28 and an observation group of 29. The control group was given conventional rehabilitation and routine CIMT, while the observation group was additionally provided with interactive scalp acupuncture. In the observation group the CIMT lasted for 30 minutes while the needles were retained. Then, after the needles were removed, the family administered simple rehabilitation training for 2.5 hours guided by a rehabilitation therapist. The treatments were administered 5 days per week for 3 weeks as a session, and the whole treatment consisted of 3 sessions. Before, as well as 1 month and 3 months after the treatment, upper extremity motor function in both groups was evaluated using the Melbourne assessment scale 2 (MA2) and the fine motor Peabody developmental motor scales. Muscle tone in the children′s elbow flexors was assessed using the modified Ashworth scale (MAS).Results:After both 1 and 3 months of treatment, the average MA2 scores of both groups were significantly better than those before treatment, with those of the observation group significantly superior to the control group′s averages. After both 1 and 3 months, both groups′ visual-motor integration scores, grasping ability scores and total scores had improved significantly, with those of the observation group significantly better than in the control group, on average. The MAS scores of both groups were also significantly better than before the treatment, but with no significant differences between the two groups at either time point.Conclusions:Interactive scalp acupuncture combined with constraint-induced movement therapy can significantly improve the upper extremity motor functioning and fine motor ability of children with spastic hemiplegic cerebral palsy.

Objective To investigate changes in the pro-inflammatory mediator S100A8/9 and NLRP3/Caspase-1/IL-1β pathway in a rat kidney-aging model induced by D-galactose.Methods Twelve SD rats were divided into control and D-galactose groups,and injected subcutaneously in the back of the neck with D-galactose(150 mg/kg)to establish a rat model of kidney aging.Kidney samples were collected under anesthesia after 8 weeks.Kidneys were stained for senescence-associated beta-galactosidase(SA-β-Gal),mRNA expression levels of the aging-related genes p21,p16,and p53 were detected by quantitative reverse transcription-polymerase chain reaction(qRT-PCR),and histopathological changes were observed by hematoxylin-eosin(HE)and Masson staining.Serum urea nitrogen and creatinine,and catalase(CAT),glutathione peroxidase(GSH-PX),superoxide dismutase(SOD),and malondialdehyde(MDA)levels in the kidney tissues were detected.Reactive oxygen species(ROS)were detected by dihydroethdium staining and protein expression levels of collagen Ⅲ,α-smooth muscle actin(α-SMA),Protein expression of S100A8/9 was detected by immunofluorescence,and transforming growth factor(TGF)-β1 levels in kidney tissues and key factors in the NLRP3/Caspase-1/IL-1β inflammatory pathway were detected by Western Blot.A renal senescence model using HK-2 cells was constructed using H2O2 in vitro,and expression levels of the senescence proteins p21 and p16 and mRNA expression levels of the inflammatory factors IL-18 and tumor necrosis factor-α(TNF-α)were detected.Cell senescence was observed by SA-β-Gal staining.The effects of the S100A8/9 inhibitor paquinimod on expression levels of S100A8/9 and NLRP3/Caspase-1/IL-1β pathway-related proteins in the aging model were also detected.Results mRNA levels of the aging genes p21,p16,and p53 in kidney tissues were significantly increased in rats in the D-galactose group compared with the control group(P＜0.01),and SA-β-Gal staining showed a significant increase in senescent cells(P＜0.01).Serum blood urea nitrogen and creatinine levels increased(P＜0.05),CAT,GSH-PX,and SOD activities decreased(P＜0.01),while MDA activity increased in the D-galactose group(P＜0.01).Collagen Ⅲ,α-SMA,and TGFβ1 expression and the ROS content in tissues increased(P＜0.05).Glomeruli were atrophied or absent in the D-galactose group,the lumens of the renal sacs and renal tubules were enlarged,the nuclei were deeply stained and constricted,and numerous collagen fibers were deposited.Levels of S100A8 and S100A9 protein(P＜0.01),as well as NLRP3,Caspase-1,and IL-1β increased(P＜0.05).Paquinimod alleviated HK-2 cell senescence and decreased expression levels of the senescence proteins p21 and p16,and mRNA levels of the inflammatory factors IL-18 and TNF-α(P＜0.05,P＜0.01).The number of senile cells was also decreased,shown by SA-β-Gal staining(P＜0.01).Paquinimod also inhibited the protein expression of S100A8 and S100A9(P＜0.01)and NLRP3,Caspase-1,and IL-1β(P＜0.05 or P＜0.01).Conclusions S100A8/9 participates in the chronic inflammatory response by activating the NLRP3/Caspase-1/IL-1β pathway,thereby promoting D-galactose-induced renal aging.

Background:Gastric adenocarcinoma of the fundic gland type(GA-FG)and oxyntic gland adenoma(OGA)are rare variants of the gastric neoplasms exhibiting fundic differentiation.However,their endoscopic recognition and diagnosis is difficult in clinical practice.Aims:To explore the endoscopic and clinicopathological features of GA-FG and OGA,and to discuss the surgical methods and clinical outcomes.Methods:A retrospective analysis was conducted on 19 cases with a total of 22 lesions diagnosed as GA-FG or OGA through histopathology at the Shanghai Sixth People′s Hospital,Shanghai Jiao Tong University School of Medicine from January 2020 to May 2023.Data on the diagnosis,treatment and follow-up among these patients were collected and analyzed.Results:Females were slightly more than males(12:7),with an average age of 54 years.Eighteen patients had single lesions,while one had 4 synchronous multifocal lesions.All the lesions located in the non-atrophic gastric fundic area of the upper and middle third of the stomach.Nine lesions were misdiagnosed as gastric fundic gland polyps initially.The tumors were small,with the average diameter of 7.4 mm.Most of the lesions(77.3%)showed fading or whitening changes under white light endoscopy.While under magnifying endoscopy with narrow-band imaging,obscure demarcation line,and dilated intervening part and crypt-opening could be observed in over half of the lesions,but irregular microvascular pattern was absent.Six lesions exhibited submucosal infiltration(GA-FG)without lymphovascular invasions.Eighteen lesions were diagnosed as chief cell predominant type,one was parietal cell predominant type,and three were mixed type.Endoscopic submucosal dissection and endoscopic mucosal resection were performed in 17 cases.No severe perioperative complications occurred,and no local recurrence and metastasis were detected during follow-up period.Conclusions:GA-FG and OGA mainly occur in the non-atrophic gastric fundic area,with small lesions exhibiting fading changes under endoscopy.The pathological type is primarily chief cell predominant type.This kind of lesion can be easily misdiagnosed as gastric fundic gland polyps.Endoscopic therapy appears to be effective and safe for them with a favorable prognosis.

Objective: To analyze the longitudinal association between mobile phone dependence and depressive symptoms in college students, so as to provide a theoretical basis for psychological health education among college students. Methods: From November 2021 to June 2023, 2 515 first year students from 2 universities in Yunnan Province were surveyed with a questionnaire by a cluster random sampling method, including baseline survey (November 2021, T1) and three follow up visits (June 2022, T2; November 2022, T3; June 2023, T4). The Self rating Questionnaire for Adolescent Problematic Mobile Phone Use and the Depression Anxiety Stress Scales-21 (DASS-21) were used to evaluate mobile phone dependence and depressive symptoms of college students. The χ 2 test was used to analyze the difference in depressive symptoms among different demographic groups, and a generalized estimation equation model was established to analyze the association between mobile phone dependence symptoms and depressive symptoms. Results: The detection rates of depressive symptoms among university students in Yunnan Province at time points T1, T2, T3, and T4 were 23.02%, 33.36%, 34.79% and 35.51%, respectively. There were statistically significant differences in the detection rates of depressive symptoms among college students with different sacademic burden (T1, T2, T3, T4), different number of close friends (T1, T2, T3), as well as their father s educational level (T1), mothers educational level (T2, T4), gender (T4), major (T3, T4), education (T2, T3, T4), family residency (T1, T2), and family economic conditions (T1, T2, T4) ( χ 2= 59.68 , 49.38, 16.70, 39.31; 55.35, 26.01, 16.69; 10.22; 14.87, 11.51; 14.90; 27.81, 50.28; 9.75, 7.42, 24.76; 6.06, 4.47 ; 15.88, 14.58, 15.85, P < 0.05 ). After controlling for demographic variables and confounding factors in the generalized estimation equation model, mobile phone dependence ( β =0.11), withdrawal symptoms of mobile phone dependence ( β =0.14), and the physical and mental effects of mobile phone dependence ( β =0.14) were all positively correlated with depressive symptoms ( P <0.01). Further gender analysis showed that depressive symptoms in both boys ( β =0.13, 0.13, 0.18) and girls ( β =0.10, 0.13, 0.13 ) were associated with mobile phone dependence, withdrawal symptoms of mobile phone dependence and the physical and mental effects of mobile phone dependence ( P <0.01). Conclusions Depressive symptoms of college students are positively correlated with mobile phone dependence, and family economic conditions, academic burden and number of close friends are factors that continued to affect depressive symptoms. College students should be guided to pay attention to the impact of excessive use of mobile phones on their physical and mental health, use mobile phones reasonably to reduce the incidence of depressive symptoms among college students.

OBJECTIVE To mine adverse drug event （ADE） signals of lacosamide， and to provide references for clinically safe drug use. METHODS ADE data for lacosamide reported to the United States FDA adverse event reporting system from January 1， 2009， to December 31， 2022， were collected. Data mining was conducted using the reporting odds ratio method and Bayesian confidence propagation neural network method. Classification statistics were performed using the system organ class （SOC） and preferred terms （PT） from ADE terminology set of Medical Dictionary for Regulatory Activities （Version 25.0）. RESULTS A total of 21 360 lacosamide ADE reports were received， identifying 203 ADE signals across 24 SOCs， with 19 signals not included in the drug’s instruction. The top five PTs ranked by occurrence frequency were medication overdose， technical errors during device use， product use issues， intentional product misuse， and therapy discontinuation. The top five PTs ranked by signal strength were changes in seizure presentation type， congenital hypoplasia of depressor anguli oris muscle， multidrug resistance， brain surgery， and vagus nerve stimulator implantation. ADEs not recorded in the drug instruction included congenital hypoplasia of depressor anguli oris muscle， multidrug resistance， mitochondrial DNA mutation， dissociative identity disorder， and congenital auricular anomaly. CONCLUSIONS For lacosamide-induced ADEs that occur frequently and are already listed in the drug’s instructions， such as bradycardia and atrioventricular block， the clinical application should be careful and attentive， adjusting the dosage timely according to the patient’s condition to avoid severe ADEs. Newly discovered suspect ADEs， such as congenital hypoplasia of depressor anguli oris muscle， mitochondrial DNA mutation， overmature infant， dissociative identity disorder， pigmenturia， behavioral disorders， and dissociative disorders， should be vigilantly recognized to ensure the safety of drug use.

Objective:To describe and analyze suicide risk of patients with schizophrenia,major depressive disorder,and bipolar disorder.Methods:A total of 2 016 patients with schizophrenia,903 patients with major de-pressive disorder,and 381 patients with bipolar disorder from inpatients,clinics,or communities who met the diag-nostic criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition were recruited.All patients were interviewed by psychiatrists using the Mini International Neuropsychiatric Interview to diagnose mental disor-ders and assess suicide risk,as well as Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)to as-sess symptoms.Differences and risk factors of suicide risk among three types of mental disorders were explored u-sing multivariate logistic regression analysis.Results:In the past one month,37 patients with schizophrenia(1.8％),516 patients with major depressive disorder(57.1％),and 102 patients with bipolar disorder(26.8％)had suicide risk.Compared with patients with schizophrenia,suicide risk in patients with major depressive disorder(OR=36.50)and bipolar disorder(OR=20.10)increased.Female(OR=1.87),smoking(OR=1.76),family history of suicide(OR=5.09),higher score of CRDPSS hallucination(OR=1.80),and higher score of CRDPSS depression(OR=1.54)were risk factors of suicide risk of patients.Conclusions:Suicide risk of patients with ma-jor depressive disorder and bipolar disorder is higher than that of patients with schizophrenia.In clinical practice,it is important to regularly assess suicide risk of patients.Patients who experience symptoms of hallucination and de-pression should be paid more attention to.
