BackgroundPatients with schizophrenia and depressive disorders exhibit abnormalities in perceptual processing. Previous perceptual studies are mainly based on asking participants to fill in a questionnaire， and little research has been undertaken on objective behavior in patients with schizophrenia and depressive disorders. ObjectiveTo explore the behavioral changes in vibrotactile sense among patients with schizophrenia and depressive disorders， so as to enrich relevant findings in objective behavioral research. MethodsFrom March 2021 to September 2023， 33 patients with schizophrenia and 31 patients with depressive disorders in the outpatient and inpatient departments of Beijing Huilongguan Hospital and met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） diagnostic criteria were enrolled. And another 34 healthy controls were concurrently recruited at Beihang University and Beijing Huilongguan Hospital. Patients with schizophrenia were assessed using Positive and Negative Symptom Scale （PANSS）， and patients with depressive disorders were assessed using Hamilton Depression Scale-17 item （HAMD-17）. The vibrotactile sensitivity of the left hand in all participants was tested in a delay match-to-sample procedure， and the correct rate of vibrotactile delayed discrimination task was compared among the three groups. ResultsCompared with healthy controls， a reduction was found in the correct rates at index finger， middle finger and ring finger in patients with schizophrenia （P<0.01）， the average correct rate at five fingers in patients with schizophrenia （P=0.001）， and the correct rate at thumb in patients with depressive disorders （P=0.026）. No statistical difference was reported in correct rate of vibrotactile delayed discrimination task between patients with depression disorders and schizophrenia （P>0.05）. The average correct rate of vibrotactile sense in schizophrenia group was not significantly correlated with the duration of disease， age of onset， chlorpromazine equivalent doses and PANSS score （r=0.058、0.045、0.114、-0.194， P>0.05）. The average correct rate in depressive group was negatively correlated with age of onset （r=-0.415， P=0.020）， but not significantly correlated with the duration of disease and HAMD-17 score （r=-0.044， 0.142， P>0.05）. ConclusionPatients with schizophrenia and depressive disorders have impaired vibrotactile sense. The vibrotactile sense is impaired in index， middle and ring fingers among patients with schizophrenia， and in thumbs of patients with depressive disorders. Moreover， the impairment in patients with depressive disorders may be related to the age of onset. ［Funded by 2023 Hebei Provincial Graduate Innovation Funding Project （number， CXZZSS2023140）］

Objective:To explore the evaluation value of serum levels of positive pentameric protein 3 (PTX3) and creatine kinase isoenzyme MB (CK-MB) on volume load in patients with chronic decompensated heart failure (CDHF).Methods:A total of 300 CDHF patients who visited the Xingtai Central Hospital from July 2019 to July 2022 were selected and divided into a capacity overload group ( n=182) and a non capacity overload group ( n=118) based on their capacity balance level. Two clinical data sets were compared and analyzed. The receiver operating characteristic (ROC) curve was used to analyze the evaluation value of serum PTX3 and CK-MB levels on the volume load of CDHF patients. The clinical disease characteristics of the two groups of patients were analyzed using univariate analysis, and the influencing factors of volume load of CDHF patients were analyzed using logistic regression. A column chart model was constructed and validated. Results:The body mass index (BMI), waist circumference, systolic blood pressure, diastolic blood pressure, fasting blood glucose (FBG), glycosylated hemoglobin (HbA 1c), C-reactive protein (CRP), uric acid (UA), homeostasis model assessment of insulin resistance (HOMA-IR) of patients in the capacity overload group were higher than those in the non-capacity overload group, and the differences were statistically significant (all P<0.05). The PTX3, CK-MB, pulmonary capillary wedge pressure (PCWP), and CVP levels of patients in the capacity overload group were higher than those in the non-capacity overload group, while albumin, hemoglobin, and hematocrit were lower than those in the non-capacity overload group, and the differences were statistically significant (all P<0.05). The ROC curve showed that the area under the curve (AUC) of PTX3 and CK-MB for predicting capacity overload in CDHF patients are 0.795 and 0.718, with sensitivity of 86.2% and 83.7%, specificity of 65.4% and 68.6%, respectively, indicating high predictive accuracy; The AUC of the two joint predictions is 0.817, the sensitivity was 92.5%, and the specificity was 70.6%. The prediction accuracy was higher than PTX3 ( Z=3.812, P<0.05) and CK-MB ( Z=3.365, P<0.05). PTX3, CK-MB, albumin, hemoglobin, hematocrit, PCWP, and central venous pressure (CVP) were all influencing factors of volume load status in CDHF patients (all P<0.05). The column chart risk prediction model established based on these factors had high accuracy and strong applicability in clinical treatment. Conclusions:Serum PTX3 and CK-MB levels are influencing factors for volume overload in CDHF patients. A column chart model constructed in combination with indicators such as albumin, hemoglobin, hematocrit, PCWP, and CVP has high predictive value for the volume overload status of CDHF.

Cow′s milk protein allergy (CMPA) is one of the most common presentations of food allergy seen in early childhood.It is an abnormal immune response caused by cow′s milk protein.CMPA can be clinically subdivided into either immediate-onset IgE mediated or delayed onset non-IgE mediated, or both.At present, concerns regarding the early and timely diagnosis of CMPA have been high-lighted over the years and there are many expert consensus on CMPA in China, but these consensus did not distinguish IgE mediated or non-IgE mediated CMPA.In view of the obvious clinical differences between the two type of CMPA and non-IgE mediated CMPA is more common in infancy, experts focus on pediatric gastroenterology, allergy/immunology, dermatology, nutrition and child healthcare convened by the Allergy Prevention and Control Professional Committee of Chinese Preventive Medicine Association present this guideline to help practitioners in primary care settings to early recognize and make suitable management of non-IgE mediated CMPA in China.The guideline incorporates the cutting-edge international guidance and the actual situation of Chinese children describing in detail the types, clinical features, diagnosis and nutritional intervention of non-IgE mediated CMPA.There are 42 recommendations in 7 categories in total referring to the common questions related to non-IgE mediated CMPA.

Objective:To analyze the efficacy and safety of the biological agent infliximab (IFX) in the treatment of pediatric Crohn′s disease.Methods:A total of 86 children with Crohn′s disease who had received IFX in three hospitals (Ruijin Hospital, Ruijin Hospital North and Shanghai Children's Hospital) in Shanghai from January 2007 to December 2017 were included in this retrospective study. The efficacy of IFX was assessed by comparing clinical and laboratory data before and after IFX treatment. Student t test, Mann-Whitney U test or chi-square test were used to analyze the data of the two groups. Logistic reggression analysis were used to analyze the effects of variables such as age, clinical characteristics, disease behavior and combined medications on the efficacy and safety of IFX. Results:Among the 86 children with Crohn′s disease in the study, 50 were males and 36 females. The IFX treatment was initiated at 12.0 (7.1, 13.6) years of age, and the follow-up period was 94.1 (47.8, 185.5) weeks. Efficacy analysis showed that in the induction remission phase, the clinical response rate was 97% (79/81) and the remission rate was 74% (60/81). In the maintenance remission phase, the clinical response rate was 75% (51/68) and the remission rate was 68% (46/68). After 34 weeks of treatment with IFX, pediatric Crohn′s disease activity index (PCDAI) (5 (0, 10) vs. 36 (26, 45)), C-reactive protein (3 (1, 8) vs. 8 (3, 31) mg/L), erythrocyte sedimentation rate (10 (6, 10) vs. 35 (20, 50) mm/1 h), platelet ( (327±107)×10 9vs. (438±159) ×10 9/L), albumin ((37±6) vs. (30±6) g/L), hemoglobin ((116±16) vs. (103±18) g/L), change of body weight (-0.5±1.2 vs. -1.0±0.9), anemia (29% (20/68) vs. 75% (51/68)), and perianal disease (13/21 vs. 0) were significantly improved (all P<0.05). By the end of 34 weeks of IFX treatment, 25% (17/68) of children experienced secondary loss of response to IFX. Logistic reggression analysis showed that PCDAI>30 was positively correlated with secondary loss of response ( OR=3.823, 95% CI 1.015 -15.328, P=0.048), and combined with azathioprine was conducive to maintaining efficacy of IFX ( OR=0.440, 95% CI 0.106 -1.033, P=0.044). The IFX-related adverse events included infusion reactions in 17% (15/86) and infections in 42% (36/86) of children. Analysis showed that age<6 years was a risk factor for infusion reactions (χ 2=6.556, P=0.010), and combined use of steroids (χ 2=5.230, P=0.022) may increase the incidence of infection. Conclusions:IFX is effective in the treatment of pediatric Crohn′s disease with favorable safety. Reducing secondary loss of response to IFX is an urgent issue that need to be addressed. At the same time, it is necessary to pay close attention to the adverse events during IFX treatment.

Objective To observe the effect of Ziyin-Jianghuo formula in treatment of Yin deficiency generating intrinsic heat type of the levels of monoamine neurotransmitters and estrogens in rats, and investigate its intervention in the neuroendocrine system. Methods There were 7 groups, which were sham operation group, model control group, estrogen tablet group, Gengnian capsule group, Ziyin-Jianghuo formula low, medium and high dose groups. Castration was performed by castration (extraction of ovaries) plus hot traditional Chinese medicine. The rats in the treatment group were given the above drugs 24 hours after the last administration of the hot Chinese medicine, once a day for 30 consecutive days. The sham operation group and the model control group were given an equal volume of purified water by simultaneous intragastric administration. The serum estradiol (E2), luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin (PRL) levels,uterine coefficient and monoamine neurotransmitters dopamine (DA), norepinephrine (NE), serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA) content in the hypothalamus were detected after 12 hours of the last treatment. Results Compared with the model group, the levels of serum FSH (4.39 ± 0.22 IU/L, 2.89 ± 0.91 IU/L, 2.84 ± 0.98 IU/L vs. 5.51 ± 0.24 IU/L), LH (14.48 ± 0.24 IU/L, 11.46 ± 0.33 IU/L, 5.28 ± 1.31 IU/L vs. 15.02 ± 0.37 IU/L) in the low, middle and high doses of Ziyin-Jianghuo formula significantly decreased (P<0.05), the levels of serum E2 (39.84 ± 6.08 pmol/L, 48.65 ± 6.77 pmol/L, 64.96 ± 7.97 pmol/L vs. 33.16 ± 4.62 pmol/L) significantly increased (P<0.05). The content of DA, 5-HT, 5-HIAA in the hypothalamus and the 5-HT/NE (0.48 ± 0.02, 0.43 ± 0.03, 0.27 ± 0.02 vs. 0.67 ± 0.02), 5-HIAA/5-HT (1.74 ± 0.09, 1.71 ± 0.10, 1.80 ± 0.17 vs. 2.00 ± 0.10) in the low, middle and high doses of Ziyin-Jianghuo formula significantly decreased ( P<0.05), the content of NE (663.34 ± 9.81 ng/kg, 695.94 ± 10.54 ng/kg, 790.76 ± 16.35 ng/kg vs. 602.95 ± 13.24 ng/kg) in the hypothalamus in the low, middle and high doses of Ziyin-Jianghuo formula significantly increased (P<0.05). The levels of serum PRL (10.16 ± 1.26 μg/L, 7.22 ± 1.26 μg/L vs. 14.80 ± 1.64 μg/L) in the middle and high doses of Ziyin-Jianghuo formula significantly decreased (P<0.05). Conclusions The Ziyin-Jianghuo formula has a significant positive regulation effect on the neuroendocrine system of menopausal Yin deficiency generating intrinsic heat type of rats, and this process is dose-dependent and can improve a series of symptoms caused by autonomic dysfunction.

Objective: To investigate the incidence and risk factors of extraintestinal manifestations (EIMs) in children with inflammatory bowel disease (IBD). Methods: The clinical data of 161 children with IBD was collected from the electronic medical records in the Department of Pediatrics, Ruijin Hospital, Shanghai Jiao Tong University, School of Medicine from January 2012 to December 2017. These patients were divided into Crohn′s disease (CD) group and ulcerative colitis (UC) group, accounting for 82.0% (132 cases) and 18.0%(29 cases), respectively. The incidence of EIMs in each group was analyzed. The potential risk factors of EIMs including the IBD phenotype, gender, age, location of the CD lesion, disease activity of CD, and the presence of perianal lesion were analyzed with logistic regression model. Results: Eighty-eight patients (54.7%) had EIMs. The main EIMs were immune-mediated EIMs and growth retardation, accounting for 41.0% (66/161) and 24.2% (39/161), respectively. Aphthous ulcer (39/161, 23.0%) was the most common symptom among immune-mediated EIMs, followed by arthropathy (20/161, 12.4%) and skin lesions (19/161, 11.8%). Forty-three patients (26.7%) had EIMs before being diagnosed as IBD. Fifty-eight (65.9%) patients had only one EIM during the whole course of IBD. By logistic regression analysis, CD (OR=5.536, 95%CI:1.825-16.788) and perianal disease (OR=1.969, 95%CI:1.035-3.746) were the risk factors of immune-mediated EIMs. Meanwhile, CD (OR=11.319, 95%CI: 1.487-86.179), younger than six-year-old at diagnosis (OR=8.556, 95%CI: 3.109-23.545), moderate to severe activity of CD (OR=3.447, 95%CI: 1.196-9.934) and perianal disease (OR=3.361, 95%CI: 1.720-7.793) increased the risk of growth retardation. Conclusions The children with IBD have a high incidence of EIMs, which were more common in CD than in UC. The risk factors of developing EIMs include CD, perianal diseases, younger than six-year-old at diagnosis and moderate to severe activity of CD.

Objective: To analyze the clinical characteristics of chronic pancreatitis (CP) and evaluate its impact on growth of children. Methods: A retrospective study was conducted in 94 children (male 49 cases, female 45 cases) who were diagnosed with CP in the Department of Pediatrics, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from August 2008 to July 2015. Clinical characteristics, such as features of abdominal pain, etiologies, image data, levels of serum amylase and lipase, and physical development data were extracted from electronic medical records. The comparison between groups based on etiology or with normal control was performed with student′s t test. Results: The age of first episode was (8.2±3.7) years. There were 61 (65%) children diagnosed with idiopathic CP, and 25 (27%) with anatomic abnormalities. The age of onset in the group with anatomic abnormalities was lower than that in the idiopathic CP group ((6.3±3.5) vs. (8.9±3.4) years, t=3.211, P=0.002). There were 51 (54%) patients with serum amylase elevation, 41(44%) patients with lipase elevation, and 35 (37%) with elevation in both. The questionnaire showed that 28 out of 30 children had moderate to severe abdominal pain. The patients′ weight standard score (SDS) was significantly lower than the overall average in normal control (-0.4±1.1 vs. 0, t=-3.308, P=0.001). Meanwhile, the mean level of insulin like growth factor-1 (IGF-1) SDS of 35 children was significantly decreased (-1.8±1.8 vs. 0, t=-6.136, P<0.01). There were 69% (37/54) patients diagnosed by magnetic resonance cholangiopancreatography (MRCP) combined with magnetic resonance imaging (MRI), higher than that diagnosed by abdominal ultrasound (29%, 27/94). Conclusions Idiopathic CP and anatomic abnormalities were the two main etiologies. Normal level of serum amylase and lipase or negative finding of ultrasound cannot exclude CP, while MRCP and MRI should be considered to improve CP diagnostic rate. It is noteworthy that growth delay would happen in children with CP history.
