Objective: To explore the influence of group psychological counseling on the mental health of children with mother s authoritarian parenting. Methods: From November 2022 to February 2023, 76 students from grades 4 to 6 whose mother showed authoritarian parenting style, while fathers adopted no authoritative, authoritarian or democratic parenting style and who scored ≥65 on the total MHT were selected using the Parenting Style Questionnaire (PBI) and the Mental Health Diagnostic Test (MHT). All the participants and their mothers were randomly assigned to the intervention and control groups. Before and after the intervention, participants filled out questionnaires on parental bonding instrument and mental health test. Control group: regular delivery of mental health education information, 2 times per week, for 8 weeks, without any other intervention. Intervention group: group counseling activities were conducted once a week. Each intervention lasted 1.5-2 hours and lasts for 8 weeks. Before and after the intervention, participants filled in the family parenting style and mental health screening questionnaires. Results: After the intervention, compared with the control group, students in the intervention group showed a significant decrease in the total scale score of the MHT, learning anxiety, social anxiety, allergic tendency, physical symptoms, fear tendency, and impulsive tendency ( t=-0.43, -1.04 , -0.81, P >0.05). After intervention, the intervention group students showed a significant decrease in psychological diagnosis test scores, learning anxiety, anxiety towards others, allergic tendencies, physical symptoms, phobic tendencies, and impulsive tendencies compared to the control group students ( t=-20.00, -5.06, -2.09, -3.36, -6.15, -4.76, -5.15, P <0.05). Conclusion Rregular group psychological counseling can effectively improve the academic anxiety, social anxiety, allergic tendencies, physical symptoms, fearful and impulsive tendencies of students whose mothers with authoritarian parenting style, and greatly improve their mental health.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Objective To investigate the diagnostic value of skeletal muscle and diaphragm muscle in the extremities,as assessed by bedside ultrasound,for ICU-acquired weakness in elderly patients.Methods A total of 47 elderly patients with severe illness,admitted to the intensive care unit(ICU)of the Second People's Hospital of Yuhang District from March 2023 to April 2024,were included in this study.The average age of the patients was 74.51 years.Medical Research Council(MRC)scores were assessed twice within a 24-hour interval.Among them,when MRC score＜48,20 cases were classified into the ICU-AW group,while the remaining 27 cases formed the non-ICU-AW group with MRC score≥48.Ultrasound measurements for lower extremity skeletal muscle thickness and diaphragm parameters were conducted on the first day,third day,and seventh day after ICU admission.The rate of shrinkage in upper and lower extremity skeletal muscle thickness at different time points was calculated.Differ-ences in ultrasound parameters between the two groups were compared,and ROC curve analysis was performed to evaluate the diagnostic value of upper and lower extremity skeletal muscle as well as diaphragm parameters for ICU-AW.Results Significant differences were observed in gender,age,BMI,APACHEⅡ score,SOFA score,number of mechanical ventilation cases,and number of sepsis cases between the two groups(P＜0.05).Compared to the non-ICU-AW group,the ICU-AW group exhibited higher rates of atrophy in quadriceps femoris(RF)and total quad-riceps femoris(QF)on day 3 and a lower degree of diaphragm displacement(DE)(P＜0.05).On day 7,the ICU-AW group showed higher rates of atrophy in quadriceps femoris[rectus femoris(RF),intermedius femoris(VI),and total quadriceps femoris(QF)]along with lower diaphragm parameters[diaphragm displacement degree(DE)and diaphragm thickness fraction(DTF)](P＜0.05).According to ROC curve analysis,the critical value of ICU-AW predicted by ΔRF-MLT atrophy rate on day 7 was 9.9%,AUC was 0.743,sensitivity was 75.0%and specificity was 77.8%.On day 7,the critical value of ICU-AW was 5.69%,AUC was 0.828,sensitivity was 80.0%,and speci-ficity was 77.8%.On day 7,the critical value of ICU-AW was 16.96%,AUC was 0.835,sensitivity was 60.0%,and specificity was 88.9%.On day 7,DE predicted that the critical value of ICU-AW was 1.67 cm,AUC was 0.818,sensitivity was 75.0%,and specificity was 85.2%.On day 7,DTF predicted that the critical value of ICU-AW was 33.96%,AUC was 0.889,sensitivity was 80.0%,and specificity was 85.2%.On day 7,the AUC of ICU-AW was 0.976,the sensitivity was 80.0%,and the specificity was 100%.Conclusion The quadriceps atrophy rate and diaphragm parameters measured by bedside ultrasound can identify and diagnose ICU-AW as early as possible.

Objective A porcine vocal cord injury model was established to analyze and compare the damage range of porcine vocal cords and the repair process after vocal cord injury caused by CO2 laser surgery and radiofre-quency ablation with plasma spot excitation technology.Methods Fifteen pigs,30 sides of vocal cords,were used in this study.The bilateral vocal cords of the same pig were divided into CO2 laser and radiofrequency coblation(RFC)groups respectively.CO2 laser and radiofrequency ablation with plasma spot excitation technology were used to perform ubligamental cordectomy.Three pigs were sacrificed after anesthesia on postoperative day 1 and postop-erative 3,6,9,and 15 weeks.The vocal cords were harvested for HE staining.The depth of edema degeneration zone and the fibrous tissue thickness were measured vertically in the two groups,and the postoperative vocal cord damage range and vocal cord repair process were compared between the two groups.Results The depth of edema degeneration zone in the CO2 laser group was deeper than that in the RFC group at 1 day postoperatively(P＜0.01).There was no significant difference in the depth of the edema degeneration zone between the two groups at the 3rd,6th,and 9th weeks after operation(P＞0.05).The depth of the edema degeneration zone at 3rd weeks postoperatively was less than that at 1 day postoperatively,and at 6th weeks postoperatively was less than that at 3rd weeks postoperatively for both operation modes(P＜0.05).There was no statistically significant difference be-tween 9th weeks postoperatively and 6th weeks postoperatively(P＞0.05).At the 15th week after operation,the fibrous tissue thickness of the vocal fold lamina propria in the RFC group was thinner than that in the CO2 laser group(P＜0.01).Conclusion Radiofrequency ablation with plasma spot excitation technology causes less damage to porcine vocal fold than CO2 laser.There is no significant difference between the two operation modes in terms of postoperative repair process,while the fibrous tissue in the lamina propria of the vocal fold is thinner in the RFC group when a vocal fold scar is formed.

Objective:To investigate the clinical manifestations, serological and cerebrospinal fluid test results for syphilis, imaging features, and prognoses of cerebral syphilitic gumma.Methods:The clinical data of 1 patient with cerebral syphilitic gumma admitted to Department of Neurology, Second Affiliated Hospital of Soochow University in March 2023 were retrospectively analyzed. Papers about cerebral syphilitic gumma were searched from journals in Journal Citation Reports Q1 from 2000 to 2019, journals from 2020 to 2024 in PubMed, WOS, Embase, and Scopus databases, and journals from 2000 to 2024 in Wanfang Database, CNKI, and VIP database; the clinical data of 54 patients with cerebral syphilitic gumma reported in above databases and 1 patient in our hospital were collected for pooled analysis.Results:The main clinical manifestations of 55 cerebral syphilitic gumma patients included headache (32, 58.2%), lateral limb/facial weakness (25, 45.5%), nausea and vomiting (14, 25.5%), dizziness (11, 20.0%), sensory disturbances (10, 18.2%), blurred vision (7, 12.7%), seizure (5, 9.1%)), hearing loss (5, 9.1%), tinnitus (5, 9.1%), memory loss (3, 5.5%), aphasia (3, 5.5%), dysarthria (2, 3.6%), drop attack (2, 3.6%), weakness in opening eyes (2, 3.6%), unresponsiveness (1, 1.8%), Argyll-Robertson pupil (1, 1.8%), tabes dorsalis gait (1, 1.8%), and fever (1, 1.8%). In 51 patients who reported complete serologic test results, 45 patients (88.2%) were positive for non-specific antibodies to syphilis, and all patients were positive for specific antibodies to syphilis. In 34 patients underwent cerebrospinal fluid examination, 25 (73.5%) were positive for non-specific antibodies to syphilis, and 32 (94.1%) were positive for specific antibodies to syphilis. Isolated intracranial lesion (43, 78.2%) was mostly common in imaging test, and the frequently involved cranial sites were, orderly, the frontal lobe (14, 25.5%), parietal lobe (14, 25.5%), temporal lobe (5, 9.1%), frontotemporal lobe (3, 5.5%), frontoparietal lobe (2, 3.6%), parieto-occipital lobe (2, 3.6%), nucleus pulposus (1, 1.8%), clivus (1/55, 1.8%), and cerebral peduncle of the midbrain (1, 1.8%). Thirty patients (54.5%) were misdiagnosed as having other intracranial space-occupied diseases, orderly, glioma (11, 36.7%), metastatic tumors (5, 16.7%), meningiomas (4, 13.3%), other unexplained intracranial space-occupying (4, 13.3%), brain abscess (3, 10.0%), cavernous hemangioma (1, 3.3%), intracranial lymphoma (1, 3.3%), auditory nerve and pituitary tumors (1, 3.3%). Of the 42 patients who reported prognosis after anti-syphilitic treatments, 41 had varying degrees of improvement, and one died of brain herniation.Conclusion:Because of atypical clinical manifestations and lack of clear diagnostic criteria, cerebral syphilitic gumma is often misdiagnosed as intracranial tumors; cerebral syphilitic gumma should be considered in patients with positive non-specific antibodies to syphilis/specific antibodies to syphilis in serum and cerebrospinal fluid having neurological symptoms and intracranial space-occupied foci; timely diagnosed and treated patients can prognosed well.

Hypertrophic obstructive cardiomyopathy(HOCM)is a hereditary cardiac disorder characterized primarily by septal hypertrophy and left ventricular outflow tract obstruction.Traditional therapeutic modalities,such as medications and surgeries,do not yield satisfactory outcomes in a subset of patients.The advancements have been made in novel treatments,including new drugs and percutaneous intramyocardial septal radiofrequency ablation(PIMSRA),still need further observation to obtain long-term efficacy and safety.In recent years,stereotactic body radiation therapy(SBRT)has emerged as an innovative non-invasive approach for treating HOCM.Studies indicate that SBRT allows for precise targeting of the hypertrophied septal region,causing both direct and indirect damage to targeted myocardial cells.This can alleviate left ventricular outflow tract obstruction and myocardial ischemia,fulfilling the therapeutic objective.For those with HOCM who neither respond well to medications nor are surgical candidates,SBRT offers a potential new therapeutic alternative.However,the latent risks of radiation therapy persist,such as the onset of radiation-induced heart disease(RIHD).The preliminary investigations guarantee the safety and feasibility of SBRT in HOCM management,an increased volume of clinical studies and prolonged follow-up data are essential to evaluate its real efficacy and potential hazards.In addition,research regarding the therapeutic mechanisms of SBRT for HOCM,optimal dosages and treatment durations,indications and contraindications,prevention of complications,and enhancing the precision of radiation therapy,still needs to be further exploration,to determine the best therapeutic strategies.

Objective:To explore the short-term efficacy of small dose omalizumab in refractory sinusitis with eosinophilia after extended sinus surgery.Methods:A total of 24 patients who met the diagnostic criteria for eosinophilic chronic rhinosinusitis and remained poorly controlled after multiple surgical treatments were included in this study. These patients were admitted to Hunan People′s Hospital between January 2020 and June 2022, and comprised 13 males and 11 females with an average age of (46.43±13.74) years. The patients were randomly divided into experimental group (12 cases) and control group (12 cases), both of which underwent extended sinus opening surgery. The experimental group received a small dose of omalizumab (150 mg/month) for 4 months, while no omalizumab was applied in the control group. All patients were followed up monthly, subjective and objective symptom scores were collected and compared between groups, which included visual analogue scale (VAS) score, sino-nasal outcome test (SNOT)-22 score, Lund-Mackay score, and Lund-Kennedy score. Statistical analysis was performed using SPSS 24.0 software.Results:The baseline was set at 1 month after surgery. There was no significant difference in baseline clinical characteristics between the two groups. After 4 months of treatment with omalizumab, the experimental group showed significant improvements in VAS scores for nasal obstruction, rhinorrhea, hyposmia, SNOT‐22 score, and Lund-Kennedy score (3.11±1.05 vs 6.44±1.13, 2.00±0.87 vs 6.55±1.33, 2.22±0.67 vs 7.00±1.22, 4.44±0.88 vs 15.22±1.20, 1.67±1.00 vs 7.44±0.88, respectively, all P<0.001). Compared to the control group at 4 months after baseline, the experimental group had significantly lower scores for nasal obstruction, rhinorrhea, hyposmia, SNOT-22, and Lund-Kennedy (3.11±1.05 vs 7.11±1.17, 2.00±0.87 vs 7.67±1.41, 2.22±0.67 vs 7.56±0.88, 4.44±0.88 vs 15.33±2.34, 1.67±1.00 vs 9.00±1.41, respectively, all P<0.001). During a 2-month follow-up period after drug withdrawal, the VAS, SNOT-22, and Lund-Kennedy scores of the experimental group were slightly higher than those before drug withdrawal but showed no significant difference (3.44±1.33 vs 3.11±1.05, 2.22±1.09 vs 2.00±0.86, 2.55±0.88 vs 2.22±0.66, 4.77±0.97 vs 4.44±0.88, 2.11±1.05 vs 1.67±1.00, respectively, all P>0.05). Conclusion:For patients of refractory sinusitis with eosinophilia, a combination of extended sinus surgery and postoperative small dosage of omalizumab can effectively control mucous inflammation, promote mucosal epithelization, and play an important role in the critical early stage of disease recovery.

Background Research on the relationship between ambient temperature and preterm birth has received increasing attention, but the conclusions of the previous literature are inconsistent. Objective To explore the impact of environmental temperature exposure in Ningbo on premature delivery of pregnant women. Methods The birth information, preterm birth data, and age of pregnant women from January 2016 to September 2020 were collected by the electronic medical record system of Ningbo Women’s and Children’s Hospital. Meteorological data for the same period were obtained through Ningbo Meteorological Bureau, including daily average temperature, daily average relative humidity, and daily average air pressure. Daily concentrations of SO₂, NO₂, and PM₁₀ were derived through the air quality real-time release system on the website of Ningbo Environmental Protection Bureau. A distributed lag nonlinear model was used to analyze the impact of environmental temperature on preterm birth by stratifying pregnant women’s age and birth delivery mode. Results The incidence rate of preterm birth in Ningbo from 2016 to 2020 was 5.91%. The exposure-response curve between environmental temperature and preterm birth presented a “U” shape. Taking 22.5 ℃ as a reference, the cumulative effect of 31 ℃ (the 95th percentile) and 32 ℃ (the 99th percentile) over a 21-day lag on preterm delivery was statistically significant, and the related RR (95%CI) values were 1.67 (1.05-2.65) and 1.85 (1.09-3.14) respectively. The results of stratified analysis showed that among pregnant women ≥30 years old, the 21-day cumulative effects of 31 ℃ and 32 ℃ on preterm delivery were statistically significant, and the related RR (95%CI) values were 2.09 (1.08-4.05) and 2.36 (1.11-5.03) respectively; among pregnant women with natural delivery, the 21-day cumulative effect of 32 ℃ on preterm delivery was statistically significant, and the RR (95%CI) was 1.95 (1.02-3.74). Conclusion Exposure of pregnant women to high temperature during pregnancy could increase the risk of preterm birth, and there is a delayed cumulative effect.

Background and Objectives: Psoriasis is a chronic inflammatory skin disease, which the mechanisms behind its initiation and development are related to many factors. DMSCs (dermal mesenchymal stem cells) represent an important member of the skin microenvironment and play an important role in the surrounding environment and in neighbouring cells, but they are also affected by the microenvironment. We studied the glucose metabolism of DMSCs in psoriasis patients and a control group to reveal the relationship among glucose metabolism, cell proliferation activity，and VEC (vascular endothelial cell) differentiation in vitro, we demonstrated the biological activity and molecular mechanisms of DMSCs in psoriasis. Methods: and Results: We found that the OCR of DMSCs in psoriatic lesions was higher than that in the control group, and mRNA of GLUT1 and HK2 were up-regulated compared with the control group. The proliferative activity of DMSCs in psoriasis was reduced at an early stage, and mRNA involved in proliferation, JUNB and FOS were expressed at lower levels than those in the control group. The number of blood vessels in psoriatic lesions was significantly higher than that in the control group (p＜0.05), which the mRNA of VEC differentiation, CXCL12, CXCR7, HEYL and RGS5 tended to be increased in psoriatic lesions compared to the control group, in addition to Notch3. Conclusions We speculated that DMSCs affected local psoriatic blood vessels through glucose metabolism, and the differentiation of VECs, which resulted in the pathophysiological process of psoriasis.
