Objective:To investigate the status quo and influencing factors of support perception of spouses of breast cancer patients, and to provide reference for clinical intervention.Methods:A cross-sectional study was conducted to facilitate the selection of 180 breast cancer patients who were treated at the Sun Yat-sen University Cancer Center from January 2022 to June 2023. The general information questionnaire, the Perceived Support Scale for Spouses of Breast Cancer Patients, the Hospital Anxiety and Depression Scale, the Locke-Wallace Marriage Adjustment Scale, and the Brief Illness Perception Questionnaire were used to investigate them. Multiple linear regression was used to analyze the influencing factors of perceived support level of spouses of breast cancer patients.Results:A total of 180 patients were admitted ultimately, all of them were females, aged (49.88 ± 8.95) years old. The total score of Perceived Support Scale for Spouses of Breast Cancer Patients was (62.38 ± 6.54) points. The average scores of each dimension from high to low were emotional support (2.70 ± 0.48) points, information support (2.65 ± 0.52) points and actual support (2.51 ± 0.62) points. There were significant differences in the scores of spouse support perception among breast cancer patients with different educational levels, surgical methods and self-care ability ( F=4.08, 17.63, t=2.41, all P<0.05). Pearson correlation analysis showed that the total score of Perceived Support Scale for Spouses of Breast Cancer Patients was negatively correlated with anxiety score, depression score and disease perception score ( r=-0.388, -0.410, -0.350, all P<0.01), and positively correlated with marital adjustment score ( r=0.692, P<0.01). The results of multiple linear regression showed that education level, surgical method, anxiety, depression, disease perception and marital adjustment were the influencing factors of spouse support perception level of breast cancer patients ( t values were 3.04-4.44, all P<0.05 ), which could explain 54.6 % of the total variation. Conclusions:The level of support perception of spouses of breast cancer patients needs to be improved. Education level, surgical method, anxiety, depression, disease perception and marital adjustment are the influencing factors of patients ′ perception of spouse support level.

Objective:To investigate the clinical and electrophysiological characteristics of facial onset sensory motor neuronopathy (FOSMN) syndrome.Methods:Ten patients diagnosed with FOSMN syndrome in Peking Union Medical College Hospital from January 2012 to December 2022 were included. The clinical and electrophysiological characteristics of patients were analyzed and summarized, and the genetic testing was also performed in these patients.Results:The age of onset was (56.6±6.5) years, and the longest survival duration of disease was 10 years. All patients had numbness around the face and mouth as the first symptom and abnormal blink reflex. A total of 52 sensory nerve conduction nerves were detected, among which 2 median nerves and 2 μlnar nerves showed decreased amplitude of sensory nerve action potential. Needle electromyography showed neurogenic lesions, with both progressive and chronic denervation. Whole exome sequencing identified the heterozygous variant c.272A>C in the exon 4 of the SOD1 gene resulting in the amino acid change p.Asp90Ala in 1 patient. In all patients, the disease progressed relentlessly and eventually led to involvement of respiratory muscle. Conclusion:FOSMN syndrome is characterized by abnormal blink reflex and sometimes abnormal sensory nerve conduction may be shown on electrophysiologic testing.

Objective:To summarize the clinical features, diagnosis, treatment, and outcomes of necrotizing pneumonia(NP)in children, so as to improve the understanding of NP.Methods:Children with NP admitted to the Children′s Medical Center of Hunan Provincial People′s Hospital from December 2012 to June 2020 were selected and divided into respiratory support group(nine cases) and non-respiratory support group(27 cases) according to whether they received respiratory support; and they were also divided into pleural effusion group(28 cases) and non-pleural effusion group(eight cases) according to whether combined with pleural effusion.The clinical data of all children were collected, and the differences between different groups were compared.Results:There were thirty-six children with NP, included 14 boys and 22 girls, with a median age of 30(12, 49) months, and the disease duration was 34(25, 42)days.All children had cough, 34 cases had fever, and the fever peak was 39.5(39.1, 40.0) ℃.Laboratory tests(all peaks) showed that blood white blood cell count was 20.77(15.65, 28.35)×10 9/L, neutrophil count was 15.11(8.52, 20.65)×10 9/L, C-reactive protein(CRP) was 104.00(23.45, 146.50)mg/L, D-dimer was 5.12(1.88, 8.04)mg/L, and lactate dehydrogenase(LDH) was 347.95(284.68, 447.81)U/L.The detection rate of pathogens was 58.33%(21/36), and the most common was Staphylococcus aureus(28.57%, 6/21). Eight cases underwent surgical treatment, including five cases of thoracoscopic surgery and three cases of thoracotomy.All patients improved and were discharged from hospital.The differences in hospital stay, white blood cell count, CRP, procalcitonin and LDH levels between respiratory support group and non-respiratory support group were statistically significant, and the median age, white blood cell count, CRP, D-dimer and LDH between pleural effusion group and non-pleural effusion group were statistically significant(all P<0.05). Further multivariate Logistic regression analysis showed that LDH was a risk factor for NP children receiving respiratory support( P<0.05), the area under the ROC curve of LDH was 0.802, whose the cut-off value was 471.21 U/L.There were no statistically significant differences in the indexes between effusion group and non-pleural effusion group. Conclusion:Children with NP are prone to repeated high fever, high inflammatory markers, and a long course of disease.Staphylococcus aureus is the most common pathogen.Serum LDH≥471.21 U/L is an early independent predictor of respiratory support for NP.

Objective To explore the influence of negative lymph node count (NLNC) on the prognosis of patients with gastric signet ring cell carcinoma (GSRC) and develop a prognostic nomogram based on NLNC. Methods On the basis of the SEER database, 2 101 patients diagnosed with GSRC were collected and randomly divided into the modeling group and validation group to test the relationship between clinicopathological characteristics and the prognosis of GSRC. The multivariate Cox proportional hazard regression model was used to analyze the independent risk factors affecting overall survival and establish a prognostic prediction model. The consistency index (C-index), calibration curve, net reclassification index (NRI), integrated discrimination improvement (IDI), and decision curve analysis (DCA) were used to evaluate the accuracy and clinical applicability of the nomogram. Results All patients were divided according to the ratio of 7:3, with 1 473 in the modeling group and 628 in the validation group. NLNC > 10 (HR=0.578, 95%CI: 0.504-0.662, P < 0.001) was a protective factor for the prognosis of patients with GSRC, and the nomogram model was established based on multivariate Cox proportional hazards model. The C-index values of the nomogram were 0.737 (95%CI: 0.720-0.753) and 0.724 (95%CI: 0.699-0.749) in the modeling and validation groups, respectively, showing good discrimination. The calibration curves showed high consistency of the model. NRI=17.77%, continuous NRI=36.34%, and IDI=4.2% indicated that the model had positive returns compared with the traditional model. The DCA was far from the baseline, indicating that the model had good clinical applicability. Conclusion The increase in NLNC is a favorable factor for the prognosis of patients with GSRC, and a relatively accurate nomogram was established to predict the prognosis of patients with GSRC and help clinicians conduct individualized prognostic evaluations.

Conclusions:The new type of tracheal tube fixation device "dual fixation" for critically ill patients with mechanical ventilation through oral endotracheal intubation is visually beautiful, and has good firmness and comfort. It can effectively reduce the occurrence of adverse events and has good application value.

Objective: To explore the effect of obesity on the treatment for femoral neck fracture in patients with SuperPATH hip replacement. Methods: Seventy patients who were treated with SuperPATH hip replacement in the Second People's Hospital of Wuxi from January 2014 to January 2017 were selected in the study.Based on their body mass index(BMI), the patients were divided into obesity group(BMI≥30kg/m²) (23 cases), overweight group(BMI: 25-30kg/m²) (22 cases), and normal group(BMI: 18.5-25kg/m²)(25 cases). The incision length, operation time, blood loss, blood transfusion rate, pain score, hip joint function score, imaging measurement results and postoperative complications were compared among the three groups. Results: All 70 patients received the operation successfully.The incision length of the obesity group was (7.4±0.2)cm, which of the overweight group was (7.2±0.1)cm, which of the normal group was (7.1±0.8)cm, the difference among the three groups was statistically significant (F=24.671, P<0.001). The patients were followed up for 9-13 months.The acetabular anteversion angle, acetabular abduction angle, pain score, mobility of hip joint, walking ability score in the obesity group were (17.8±1.2)°, (40.9±3.4)°, (1.26±0.61)points, (95.43±7.89)°, (8.10±0.27)points, respectively, which in the overweight group were (16.7±3.3)°, (42.9±2.9)°, (1.23±0.58)points, (96.78±3.22)°, (8.20±0.92) points, respectively, which in the normal group were (15.8±2.7)°, (43.9±5.1)°, (1.24±0.78)points, (97.12±6.44)°, (8.20±0.48)points, respectively.The difference of acetabular abduction angle among the three groups was statistically significant (F=9.803, P=0.002). In the obesity group, there were two cases of incision infection, two cases of deep venous thrombosis and one case of pulmonary complication, the incidence rate of complications was 5%.In the overweight group, there was one case of superficial incision infection, and one case of deep vein thrombosis, the incidence rate of complications was 2%.In the normal group, there was one case of deep venous thrombosis, the incidence rate of complications was 1%.The difference of incidence rate of complications among the three groups was statistically significant(χ²=15.31, P<0.01). Conclusion Obesity increases the surgical risk of SuperPATH total hip replacement, and more attention should be attached to perioperative and post-operative treatment for such patients.

Objective: To investigate the effect of square dance on bone mineral density and osphyarthrosis and gonitis in postmenopausal women. Methods: The postmenopausal women who danced on a square in the Second Hospital of Wuxi Affiliated to Nanjing Medical University from January 2014 to January 2015 were selected and divided into different groups by age.Each group of subjects received the bone mineral density test of their lumbar vertebral body 1-3, so as to analyze the difference between the bone mineral density of each vertebral body and the corresponding age, as well as the relationship between the age and the bone mineral density.The bone mineral density of their lumbar vertebrae was measured one year later, and the incidence rates of osphyarthrosis and gonitis were observed, thus the influence of square dancing on bone mineral density and the incidence of osphyarthrosis and gonitis of postmenopausal women was studied. Results: There was statistically significant difference in the bone mineral density for lumbar vertebrae of different age groups(F=74.213, P<0.01), among which the bone mineral density of lumbar vertebrae 1~3 in the age group of 45-60 showed a decreasing trend, with a medium negative correlation with age(r=0.978). After dancing on a square for 1 year, the bone mineral density of lumbar vertebral body 1-3 of subjects in the age group of 45-50, the age group of >50-55, the age group of >55~60, the age group of >60-65, the age group of >65-70 and the age group of over 70 were (149.51±31.65)mg/cm³, (118.98±34.55)mg/cm³, (103.56±23.44)mg/cm³, (86.88±34.21)mg/cm³, (69.89±29.72)mg/cm³, (61.22±34.21)mg/cm³, respectively, which increased slightly; the bone mineral density of the age group of 45-50, the age group of >50-55 and the age group of >55-60 increased significantly(F=8.012, 3.567, 4.774, all P<0.05). Square dancing had no significant effect on the incidence of osphyarthrosis and gonitis of postmenopausal women. Conclusion The age group of 45-60 is the most obvious period of bone mineral density decline for women.Square dancing can effectively improve the bone mineral density of postmenopausal women in this age group, but has no obvious effect on the improvement of the bone mineral density of women in other age groups.Square dancing has no effect on the incidence of osphyarthrosis and gonitis of postmenopausal women.

Objective: To summarize the clinical characteristics and nerve conduction damage in patients with early POEMS syndrome, and to explore the value of segment nerve conduction velocity in the diagnosis of POEMS syndrome. Methods: A total of 73 patients with POEMS syndrome and 27 healthy controls in Peking Union Medical College Hospital from September 2009 to June 2019 were recruited in this study. The motor and sensory nerve conduction characteristics of median, ulnar, tibial, and peroneal nerves and the clinical features of the participants were analyzed. The analysis parameters included: (1) distal motor latency (DML), compound muscle action potential (CMAP); (2) the median velocity from elbow to wrist, the median velocity from axillary to elbow, the ulnar velocity from the site below elbow to wrist, the ulnar velocity from the site above elbow to below elbow, the ulnar velocity from axillary to the site above elbow, the tibial velocity from ankle to knee, the peroneal velocity from ankle to fibulae capitulum; (3) sensory nerve conduction velocity and amplitude of these nerves; (4) terminal latency indices (TLI) of median; (5) motor nerve conduction blocks. Results: Peripheral nerve damages were the initial symptoms in thirty-two patients in this group, accounting for 43.8% (32/73), and 81.3% (26/32) of these patients only showed numbness in lower extremities. All POEMS syndrome patients with numbness had abnormal sensory nerve conduction, and 9.5% (7/73) of patients without sensory symptoms also had abnormal sensory nerve conduction. On the other hand, the decrease of CMAP amplitude corresponded to clinical muscle strength decline and motor dysfunction. In the patients with POEMS syndrome, motor nerve conduction in the lower limbs were more likely to be affected and the damages were more severe than in the upper limbs: the proportion of CMAP disappearance in the lower limbs and upper limbs was 47.6% (112/235) vs 2.8% (7/252; χ²=133.698, P<0.01). Sensory nerve conduction damage was more severe than motor nerve conduction: the proportion of amplitude disappearance in sensory and motor conduction was 43.0% (141/328) vs 24.4% (119/487; χ²=133.698, P<0.01). The slowing of motor nerve conduction velocity was more common than the decrease of CMAP amplitude: the rate of slowing down of motor nerve conduction was 88.7% (432/487), and the rate of decrease of amplitude was 52.8% (257/487; χ²=151.905, P<0.01). The DML of median and ulnar nerve in the POEMS syndrome group was longer than that in the control group (median nerve: 4.4 (3.7, 5.0) ms vs 3.2 (3.0, 3.5) ms, U=854.000, P<0.01; ulnar nerve: 3.1 (2.7, 3.8) ms vs 2.5 (2.2, 2.7) ms, U=1 077.500, P<0.01). The TLI of median nerve in patients with POEMS syndrome was significantly higher than that of healthy controls (0.40±0.11 vs 0.35±0.06, t=3.466, P=0.001). There was no statistically significant difference in nerve conduction velocity between the forearm segment and the upper arm segment in the POEMS group. Conclusions Neurological damages were common in patients with POEMS syndrome with sensory nerve damage often being the initial clinical manifestation. In patients with POEMS syndrome, the nerve damage in the lower limbs was more severe than in the upper limbs, and sensory nerve damage was more severe than motor nerve damage. Segmental motor nerve conduction results suggested that demyelination damage occurred earlier than axonal damage, and proximal lesions were slightly heavier than distal lesions. No conduction block was detected in these patients. These characteristics of segmental nerve conduction can provide more evidence for clinical diagnosis of POEMS syndrome.
