Objective:To investigate brain damage and treatment efficacy in patients with first-episode schizophrenia with comorbid auditory and visual hallucinations and cognitive decline based on brain magnetic resonance imaging (MRI).Methods:This study adopted a retrospective cohort design. Eighty patients with first-episode schizophrenia who received treatment at Wenzhou Seventh People's Hospital from January to June 2024 were included in this study. The patients were divided into an observation group (40 cases of first-episode schizophrenia with comorbid auditory and visual hallucinations) and a control group (40 cases of first-episode schizophrenia without comorbid auditory and visual hallucinations) based on whether they had symptoms of comorbid auditory and visual hallucinations. Forty healthy individuals who concurrently underwent physical examinations were included in the normal group. All patients received standardized treatment. Cranial MRI data were collected from all subjects. Cranial MRI data, Positive and Negative Syndrome Scale (PANSS) score, Global Assessment of Functioning (GAF) score, and changes in cognitive function were compared among the three groups. Additionally, the changes in cranial MRI data, PANSS score, GAF score, and the score of MATRICS Consensus Cognitive Battery (MCCB) in the observation group were compared between before and after treatment.Results:The horizontal distance between the corpus callosum and the underside of the cingulate gyrus, the vertical distance between the corpus callosum and the underside of the cingulate gyrus, and PANSS and GAF scores in the observation group were all significantly higher than those in the normal and control groups (all P < 0.05). The scores on all MCCB scales in the observation group were significantly lower than those in the normal and control groups (all P < 0.05). After treatment, the left horizontal distance between the corpus callosum and the underside of the cingulate gyrus [(5.72 ± 0.71) mm] and the right horizontal distance [(5.13 ± 0.55) mm], as well as the left vertical distance [(6.37 ± 0.69) mm] and the right vertical distance [(5.61 ± 0.67) mm], were all significantly lower than the pre-treatment values [(6.98 ± 0.83) mm, (6.07 ± 0.49) mm, (7.54 ± 0.58) mm, and (6.52 ± 0.51) mm, t = 7.30, 8.07, 8.21, 6.84, all P < 0.05]. Post-treatment PANSS scores [(39.95 ± 6.65)] were significantly lower than pre-treatment scores [(97.47 ± 18.47)], while post-treatment GAF scores [(71.26 ± 8.87)] were significantly higher than pre-treatment scores [(34.68 ± 7.71), t = 18.53, 19.69, both P < 0.05]. Post-treatment scores for the MCCB [(8.57 ± 2.45), (2.25 ± 0.47), (25.16 ± 2.43), (24.10 ± 2.64), (17.08 ± 2.25), (20.43 ± 3.76), (2.07 ± 0.36), (22.16 ± 3.24), (57.81 ± 7.69), (0.28 ± 0.05)] were significantly higher than pre-treatment scores [(5.65 ± 1.37), (1.62 ± 0.34), (21.21 ± 2.27), (20.27 ± 1.78), (12.16 ± 2.08), (14.56 ± 2.34), (1.71 ± 0.25), (17.92 ± 1.64), (40.29 ± 6.56), (0.21 ± 0.03), t = 6.58, 6.87, 7.51, 7.61, 10.15, 8.38, 5.19, 7.38, 10.96, 7.59, all P < 0.05]. Conclusions:The comorbid auditory and visual hallucinations in patients with first-episode schizophrenia, based on brain MRI findings, are closely related to cognitive decline and brain damage. After treatment, both cognitive function and cranial damage in these patients have considerably improved, which is worthy of clinical consideration.

Objective:To investigate the clinical outcome of transposition of the medial gastrocnemius muscle flap in repairing the middle and upper tibial soft tissue defects.Methods:The clinical data of patients with mid-upper tibial tissue defects admitted to the Affiliated Hospital of Shaanxi University of Traditional Chinese Medicine from September 2016 to June 2020 were retrospectively analyzed. Doppler ultrasound was used to detect and mark the blood vessels and branches of the lower limbs before surgery, the medial gastrocnemius muscle flap was designed according to the wound condition of the patient, the soft tissue defects in the middle and upper part of the tibia were repaired by transposition, and the appearance, color, feel, texture, gait and plantar flexion strength of the affected foot, as well as the recovery of the donor site were followed up after surgery. For patients with chronic osteomyelitis, the efficacy is evaluated with reference to McKee and other osteomyelitis treatment standards, including three levels: cure, improvement and recurrence.Results:A total of 11 patients were enrolled, including 9 males and 2 females, aged 48 to 69 years. The area of soft tissue defect ranged 3.8 cm×5.7 cm-14.2 cm×7.6 cm, and the flap size ranged 13.0 cm×6.0 cm-21.0 cm×13.0 cm. After surgery, one case had blisters at the distal end, which were cured after conservative measures. Other flaps and donor wounds presented good blood circulation, the shape and function recovered satisfactorily, and the incision healed uneventfully. 11 cases were followed up for 7-18 months after surgery, with an average of 13.2 months, and the appearance, color and texture of the flap were basically satisfactory. The two-point distance perception of the flap was 13-20 mm 9 months after surgery, with an average of 15 mm. At the last follow-up visit, the plantar flexion strength of the affected side was weaker than that of the healthy side, but the gait was basically normal. All 4 patients with chronic osteomyelitis met the clinical cure criteria, and there was no rash, swelling, overheat and pain, rupture, exudation and sinus tract formation at the primary lesion during the follow-up period (average 14 months), and no osteosclerosis and dead bone formation were found on X-ray examination. There was no deformity and dysfunction at the donor site. There was one case presented pigmentation at the donor site of the thigh. Some cases presented superficial scarring.Conclusions:The transposition of the medial gastrocnemius muscle flap repairs the middle and upper tibial tissue defects without sacrificing the major blood vessels, and the flap survival rate is high, the complications are minimal, and the function and morphological recovery of the receiving area are good.

Purpose: The aim of the study was to evaluate the status of psychological resilience among women in their second pregnancy and to investigate the possible influencing factors. Methods: A total of 275 women in their second pregnancy and who met the criteria were surveyed from two public hospitals in China from July 2018 to January 2019. The instruments included the General Self-designed Questionnaire, Connor–Davidson Resilience Scale, Social Support Rate Scale, and 36-item Pregnancy Stress Rating Scale. Results: The total psychological resilience score of second-pregnancy women was relatively low. Multivariate regression analysis identified five factors associated with psychological resilience: intimacy with husbands, social support utilization, gender of the first child, high-risk pregnancy of the first child, and the stress caused by worrying about the health and safety of the mother and fetus. Conclusion Women in their second pregnancy represent a unique population, and their low psychological resilience score deserves attention. Identification of factors contributing to decreased psychological resilience may enable us to design prevention and intervention strategies and to deliver specific psychological supports to pregnant women at high risk of developing negative psychology.
