Objective:To explore the classification and influencing factors of family resilience and post-traumatic growth in patients with spinal tumor.Methods:A cross-sectional investigation was conducted among 219 inpatients with spinal tumor admitted from July 2021 to July 2022. The General Demographic Information questionnaire, Chinese-Family Resilience Assessment Scale, Posttraumatic Growth Inventory, Family Crisis-Oriented Personal Evaluation Scales (F-COPES), and Social Support Rating Scale (SSRS) were used in the study. The ordinal and multivariate logistic regression analyses was applied to identify the factors associated with the classification of family resilience and post-traumatic growth.Results:Of the 219 patients, there were 62 cases of primary spinal tumors (28.3%). According to the results of latent profile analysis, the respondents were classified into three categories by family resilience and post-traumatic growth, namely family difficulty-resistant type ( n=38, 17.4%), general resilience-struggle type ( n=99, 45.2%) and family adaptation-growth type ( n=82, 37.4%). There were significant differences in occupational status, commitment to housework, family atmosphere( χ2=10.75, P=0.025; χ2=6.95, P=0.031; χ2=11.37, P=0.017), and total score of F-COPES and SSRS ( F=25.95, P<0.001; F=19.06, P<0.001)among three groups. Ordinal and multivariate logisitc regression analyses showed that retirement ( OR=2.928, 95% CI:1.098-7.808, P<0.05), family coping ( OR=1.113, 95% CI:1.063-1.165, P<0.05), and social support ( OR=1.226, 95% CI:1.103-1.362, P<0.05) were independently associated with family resilience and post-traumatic growth in patients with spinal tumor. Conclusion:Patients with spinal tumor have significant differences in characteristics by family resilience and post-traumatic growth. As a result, more targeted interventions should be provided for different categories of spinal tumor patients in the future.

Objective:To investigate the brain functional connectivity and network of patients with bipolar depression (BD) during emotion recognition, and to assess the correlation of brain functional indicators with clinical data.Methods:From August 2023 to September 2024, a total of 34 BD patients and 35 healthy controls were recruited for the study. The 17-item Hamilton depression scale(HAMD-17) and the Hamilton anxiety scale (HAMA) were used to assess the depression and anxiety symptoms of BD patients. While all the participants performed the emotion recognition task, a functional near-infrared spectroscopy (fNIRS) with 52 channels was utilized to collect their oxyhemoglobin concentrations in dorsolateral prefrontal cortex (DLPFC), medial prefrontal cortex (mPFC), and temporal lobe (TL). Brain functional indicators, including brain functional connectivity(BFC) and brain functional network (BFN) parameters, were extracted using fNIRS analysis algorithms. SPSS 26.0 software was used to perform t-test, Wilcoxon rank sum test, chi-square test, Pearson correlation and multiple linear regression analysis. Results:The emotion recognition accuracy of BD patients ((69.40±18.32) %) was lower than that of healthy controls ((76.94±6.09)%)( t=-2.13, P=0.036), and the average spending time ((4.00±1.78) s) of BD patients was longer than that of healthy controls ((2.69±1.27) s) ( t=-2.81, P=0.007). The BFC values of right DLPFC-right mPFC, right DLPFC-left TL, right DLPFC-left mPFC, right TL-right mPFC, right TL-left TL, right TL-left mPFC, right mPFC-left DLPFC, and right mPFC-left mPFC, the clustering coefficient, and small-world coefficient of BD patients were lower than those of healthy controls (all P<0.05).The characteristic path length of BD patients was higher than that of healthy controls ( t=1.27, P<0.05). For BD patients, the total score of HAMD-17 were significantly and negatively correlated with the clustering coefficient, small-world coefficients, and BFC values of right DLPFC-left mPFC and right mPFC-left DLPFC ( r=-0.45--0.27, all P<0.05).The total score of HAMA was significantly and positively correlated with the BFC value of right DLPFC-left mPFC ( r=0.30, P<0.05). The results of multiple linear regression analysis showed that the clustering coefficient ( β=-0.12, t=-0.69, P=0.009), small-world coefficients ( β=-0.22, t=-1.05, P=0.013), and BFC values of right DLPFC-left mPFC ( β=-0.47, t=-2.29, P=0.030) and right mPFC-left DLPFC( β=-0.20, t=-0.90, P=0.010) were influencing factors of depressive symptoms in BD patients. The BFC value of right DLPFC -left mPFC ( β=0.37, t=2.36, P=0.026) was influencing factor for anxiety symptoms in BD patients. Conclusions:There are abnormalities in some BFC values and BFN parameters in the DLPFC, mPFC, and TL brain regions during the emotional recognition task, which are related to the clinical symptoms. The abnormalities may be associated with the emotional recognition deficits in BD patients. These findings may provide theoretical guidance for the development of clinical intervention strategies for BD patients.

Objective:To investigate the effect of using " Four-Quadrant Pre-Positioning Method" combined with synchronous CT imaging to assist color doppler ultrasound in establishing an ideal puncture access for percutaneous nephrolithotomy (PCNL).Methods:A retrospective analysis was conducted on 113 patients with renal stones treated at the First Affiliated Hospital of Zhengzhou University from May 2021 to July 2023. Patients were divided into two groups based on the surgical method: the study group and the control group. The study group consisted of 64 patients who, from June 2022 to July 2023, underwent PCNL with the assistance of the four-quadrant pre-positioning method and color doppler ultrasound for puncture point localization. The control group consisted of 49 patients who underwent PCNL from May 2021 to May 2022. Based on the distribution of stones, both groups were further divided into three subgroups: subgroup 1: single renal pelvis or single renal calyx stones (study group: 27 patients, control group: 20 patients). Stone length was (34.27±7.69) mm vs. (39.77±11.34) mm, respectively. Subgroup 2: renal pelvis combined with a single renal calyx stone, or multiple stones in more than two renal calyces (study group: 19 patients, control group: 15 patients). Stone length was (45.77±9.50) mm vs.(40.94±11.34) mm, respectively. Subgroup 3: staghorn or cast stones (study group: 20 patients, control group: 17 patients). Stone length was (60.03±11.59) mm vs. (58.41±15.01) mm, respectively. There were no significant differences in gender, age, height, weight, side of the stone, stone length, or stone CT values between the subgroups ( P>0.05).The use of four-quadrant pre-positioning method results from multi-slice spiral CT imaging and the patient's anatomical characteristics. The 12th rib apex is taken as the origin, and the body's transverse and longitudinal axes are defined as the X and Y axes, respectively, to create the " Four Quadrants." The ideal puncture point is located within these quadrants. During the procedure, based on surface markings of the 12th rib apex, the " Four Quadrants" and ideal puncture point are identified on the patient's body surface, assisting the color doppler ultrasound in guiding the establishment of the puncture access. The puncture access establishment time, puncture first calyx success rate (criteria: for single renal pelvis or calyx stones, the first puncture access should achieve a stone-free rate >90%; for multiple renal calyx stones or staghorn stones, the first puncture access should achieve a stone-free rate >50%), surgical time, intraoperative blood loss, stone-free rate, and postoperative complications were compared between the study and control groups in each subgroup. Results:In subgroup 1, the puncture access establishment time was (4.74±2.25) minutes in the study group vs. (7.00±3.13) minutes in the control group ( P=0.006). In subgroup 2, the puncture access establishment time was (6.94±2.12) minutes in the study group vs. (9.80±2.83) minutes in the control group ( P=0.002), with the first calyx success rate being 94.7% (18/19) in the study group vs. 60.0% (9/15) in the control group ( P=0.028). The surgical time was (97.68±26.22) minutes vs. (136.29±33.00) minutes ( P=0.001).In subgroup 3, the puncture access establishment time was (8.00±2.69) minutes in the study group vs. (12.59±3.54) minutes in the control group ( P=0.001), with the first calyx success rate being 100.0% (20/20) in the study group vs. 76.5% (13/17) in the control group ( P=0.036). Intraoperative blood loss was (238.00±176.74) ml vs. (388.57±219.89) ml ( P=0.043). No significant differences were found between the two groups in terms of immediate postoperative stone-free rate (subgroup 1: 92.6% (25/27) vs. 95.0% (19/20), P=0.739; subgroup 2: 78.9% (15/19) vs. 73.3% (11/15), P=1.000; subgroup 3: 75.0% (15/20) vs. 70.5% (12/17), P=0.703) or complication rates (subgroup 1: 25.9% (7/27) vs. 25.0% (5/20), P=0.943; subgroup 2: 26.3% (5/19) vs. 40.0% (6/15), P=0.475; subgroup 3: 40.0% (8/20) vs. 41.2% (7/17), P=1.000). Conclusions:The four-quadrant pre-positioning method effectively assists in the use of color doppler ultrasound to establish an ideal puncture access during PCNL, reducing puncture access establishment time and improving the rationality of the puncture path. It also significantly reduces intraoperative blood loss, particularly for complex renal stones such as those in multiple renal calyces or staghorn stones, thereby enhancing the safety of the procedure.

COVID-19 is caused by a novel coronavirus-severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), which has being spreading around the world, posing a serious threat to human health and lives. Neutralizing antibodies and small molecule inhibitors for virus replication cycle are the main antiviral treatment for novel coronavirus recommended in China. To further promote the rational use of antiviral therapy in clinical practice, the National Center for Infectious Diseases (Beijing Ditan Hospital Capital Medical University and the First Affiliated Hospital, Zhejiang University School of Medicine) invited experts in fields of infectious diseases, respiratory and intensive care to develop an Expert Consensus on Antiviral Therapy of COVID-19 based on the Diagnosis and Treatment Guideline for COVID-19 ( trial version 10) and experiences in the diagnosis and treatment of COVID-19 in China. The consensus is concise, practical and highly operable, hopefully it would improve the understanding of antiviral therapy for clinicians and provide suggestions for standardized medication in treatment of COVID-19.

Objective:To investigate the safety and dose of 4D template (real-time adjustable angle template) in the treatment of advanced malignant tumors with 125I seeds. Methods:98 patients with advanced malignant tumors admitted to Department of Thoracic Surgery of Shaanxi Provincial Tumor Hospital were treated with 4D template-navigated radioactive 125I seed implantation from June 2018 to December 2019. Preoperative TPS plan, intraoperative optimization, postoperative verification of immediate dose and postoperative evaluation of implantation dose were performed. The treatment results were observed. Results:All 98 patients completed the seed implantation. The implantation dose of GTV of implantation site receiving external irradiation was (12 489±414) cGy and the dose of no external irradiation was (15 036±514) cGy. V 100% was 84.7%-94.1%, and 88.2%-93.7%. The implantation dose of CTV was (7 450±621) cGy, and (9 080±761) cGy. The quality of dose implantation was evaluated as: excellent in 89 cases (91%, 89/98), good in 7 cases (7%, 7/98), fair in 2 cases (2%, 2/98), and poor in 0 case, respectively. The symptom relief rate of patients with pain was 92%(36/39). The 1-and 2-year local control rates were 61%, 36% and 82%, 54% in patients treated with and without external irradiation, respectively. The difference was statistically significant ( P=0.02). The incidence rates of pneumothorax and hemoptysis were 19%(9/48) and 10%(5/48). No corresponding complications were observed in other parts of the patients. Conclusion:4D template-assisted 125I seed therapy is safe and effective for malignant tumors, and intraoperative adjustment of needle angle and dose optimization can realize the precise control of implantation dose.

OBJECTIVETo study iodine nutrition of pregnant women in different occasions and thyroid function of their neonates.

METHODSUrinary iodine of pregnant women and their serum T(3), T(4), FT(3), FT(4) were determined by chloric acid-digestion thermostatic assay and RIA, TSH determination by IRMA; neonatal umbilical cord blood TSH was determined by ELISA.

RESULTSMedian urinary iodine of pregnant women were 206.3 microg/L, 161.4 microg/L, 203.3 microg/L at 10 - 14 (first occasion), 23 - 27 (second occasion) and 39 - 40 (third occasion) week but the percentage that lower than 100 microg/L were 14.6%, 17.1%, 11.1% respectively. Serum T(3), T(4) of pregnant women was significantly higher than those women of premarital health inspection (PHIW, P < 0.001). The difference of serum T(3), T(4) of pregnant women at 10 - 14 and 39 - 40 week was not significant. Serum FT(3), FT(4) of pregnant women at 39 - 40 week were 2.61 +/- 0.47 pmol/L and 5.50 +/- 1.57 pmol/L respectively. The difference of serum TSH concentration at third occasion and first occasion of pre-pregnancy was significant but the difference of TSH frequency distribution in three groups was not significant (chi(2) = 1.138, P > 0.5). Blood TSH median neonatal umbilical cord was 1.99 mU/L but the percentage that higher than 5 mU/L was 9.4%.

CONCLUSIONFor those areas with high iodized salt coverage, pregnant women had had sufficient iodine supplement and good thyroid function. The percentage of neonates from iodine sufficient pregnant women with TSH > 5 mU/L was lower than 10%. Using the normal range of nonpregnant FT(3) and FT(4) to estimate the thyroid function of pregnant women could cause mis diagnosis.
