Objective To analyze the correlation between cumulative fluid balance volume and increasing plasma volume and aggravated clinical congestion symptoms in patients with heart failure on admission for 1～7 d,and to explore the application value of cumulative fluid balance volume in predicting volume overload.Methods Using the convenience sampling method,235 heart failure patients hospitalized from October 2022 to February 2023 in a total of 3 tertiary hospitals in Nanjing,Lianyungang,Jiangsu Province,and Zhumadian,Henan Province,were selected and classified into an increasing/decreasing plasma volume group and an aggravated/alleviated clinical congestion symptoms group.General information,clinical characteristics,and 1～7 d cumulative fluid balance volume of the study subjects were collected to compare the differences in cumulative fluid balance volume between the 2 groups.Logistic regression was used to analyze the effect of cumulative fluid balance volume on plasma volume and clinical congestion symptoms.Receiver operating characteristic curves were used to analyze the optimal cutoff value of cumulative fluid balance volume for predicting increasing plasma volume and aggravated clinical congestion symptoms.Results Excluding 15 pat ients who were discharged early and 3 patients with inaccurate records of fluid intake and excretion,a total of 217 patients were included.The incidence of positive fluid balance was lowest on day 1,at 65.90%,with the smallest cumulative volume of(0.235±0.983)L;the highest incidence of positive balance occurred on day 6,at 75.58%,with the largest cumulative volume of(2.444±5.445)L.The cumulative fluid balance at 4～7 d in the increasing plasma volume group was higher than that in the decreasing plasma volume group,and the difference was statistically significant(P<0.05);the cumulative fluid balance at 4～7 d was an independent risk factor for plasma volume elevation,and a cumulative fluid balance of 2.308,3.361,3.518,and 3.702 L at 4～7 d was predictive of a plasma volume elevation,and areas under receiver operating characteristic curve were 0.686,0.721,0.647,and 0.766,respectively.The cumulative fluid balance for 4～7 d in the aggravated clinical congestion symptoms group was higher than that in the alleviated clinical congestion symptoms group,and the difference was statistically significant(P<0.05);the cumulative fluid balance for 4～7 d was an independent risk factor for the aggravated clinical congestion symptoms,and a cumulative fluid balance for 4～7 d of 2.574,3.383,4.995,and 4.235 L predicted aggravated clinical congestion symptoms,and area under receiver operating characteristic curve was 0.640,0.693,0.654,and 0.720,respectively.Conclusion The incidence of cumulative positive fluid balance in heart failure patients is high,and the amount of cumulative fluid balance can better predict the occurrence of volume overload,and the increase of plasma volume precedes the appearance of clinical congestion symptoms.It is suggested that heart failure patients with more than 3 d of cumulative positive balance should be closely monitored,and when the cumulative positive balance exceeds 2.308 L,measures should be taken in time to drain excessive fluid,so as to avoid the incidence of volume overload.

ObjectiveTo investigate the prevalence of overweight or obesity in community patients with schizophrenia in Shanghai and to explore the related factors. MethodsStratified cluster sampling method was used and the general condition， physical examination and laboratory examination data of patients with schizophrenia who voluntarily participated in 2020 free health examination of National Basic Public Health Service were analyzed. ResultsA total of 3 200 patients were included into the study ，and the prevalence of overweight and obesity was 36.75% and 17.19%， respectively. Multivariate logistic regression analysis indicated that age between 40 and 60 （OR=1.333， 95%CI： 1.030‒1.724）， intake of first-generation antipsychotics （OR=1.413， 95%CI： 1.112‒1.796）， intake of second-generation antipsychotics （OR=1.573， 95%CI： 1.288‒1.921）， high-normal blood pressure （OR=1.549， 95%CI： 1.245‒1.927）， high-abnormal blood pressure （OR=2.824， 95%CI： 2.204‒3.619）， elevated ALT （OR=1.874， 95%CI： 1.386‒2.535）， elevated FBG （OR=1.270， 95%CI： 1.066‒1.513）， and elevated TG （OR=1.652， 95%CI： 1.335‒2.044） were the related factors that associated overweight or obesity in patients with schizophrenia. ConclusionOverweight and obesity are highly prevalent among community patients with schizophrenia in Shanghai. Age between 40 and 60， taking first-generation and second-generation antipsychotics， blood pressure higher than 120/80 mmHg， elevated ALT， elevated FBG， and elevated TG are associated with overweight or obesity in patients with schizophrenia. To provide personalized health guidance， medical staff in primary health care institutions should pay more attention to high-risk groups of overweight and obesity in schizophrenia patients at annual physical examination.

Objective:To analyze and compare the corneal higher order aberration (HOA) after femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) and small incision lenticule extraction (SMILE).Methods:A non-randomized controlled study was conducted.Sixty myopic patients (60 eyes) who underwent FS-LASIK or SMILE correction at Shandong Eye Hospital from April 2018 to January 2020 were enrolled and the data from the right eye were collected for analysis.Thirty cases (30 eyes) who received FS-LASIK in FS-LASIK group and 30 cases (30 eyes) who received SMILE in SMILE group had a preoperative equivalent spherical diopter of (-5.36±1.11)D and (-4.93±1.03)D, respectively.The HOA of the 6-mm anterior surface, posterior surface, and whole cornea were measured before surgery and at 1, 3, 6, and 12 months after surgery using Pentacam.The root mean square values (μm) of total corneal HOA, spherical aberration, coma and trefoil were obtained.Differences in the above root mean square values at different time points were compared between the two groups.The study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Shandong Eye Hospital (No.SDSYKYY20180306). Written informed consent was obtained from each subject.Results:The preoperative and 1-, 3-, 6-, 12-month postoperative total HOA of the anterior corneal surface were (0.428±0.126), (0.775±0.169), (0.811±0.194), (0.759±0.214), (0.704±0.199)μm in the FS-LASIK group and (0.409±0.094), (0.656±0.148), (0.681±0.161), (0.668±0.175), (0.648±0.160)μm in the SMILE group, with a significant overall difference ( Fgroup=5.652, P=0.024; Ftime=107.169, P<0.01). Compared with SMILE group, the postoperative total HOA of anterior corneal surface and spherical aberration at different time points were increased in FS-LASIK group, showing statistically significant differences (all at P<0.05). Compared with before surgery, the postoperative total HOA of the anterior corneal surface and spherical aberration at different time points were increased in both groups, showing statistically significant differences (all at P<0.05). In the two groups, the 6- and 12-month postoperative total HOA of the anterior corneal surface were reduced in comparison with the 3-month postoperative ones of the anterior corneal surface, and the 12-month postoperative spherical aberrations of the anterior corneal surface were significantly reduced in comparison with the 1- and 3-month postoperative ones of the anterior corneal surface, showing statistically significant differences (all at P<0.05). There were significant differences in the coma and trefoil of the anterior corneal surface between before and after the operation (coma: Ftime=47.848, P<0.01; trefoil: Ftime=2.497, P=0.046). Compared with before surgery, the postoperative coma was significantly increased in the two groups (all at P<0.05). There were significant differences in total corneal HOA and spherical aberration at different postoperative time points between the two groups (total HOA: Fgroup=8.093, P=0.008; Ftime=125.019, P<0.01.spherical aberration: Fgroup=4.771, P=0.037; Ftime=34.033, P<0.01). Compared with SMILE group, the total corneal HOA and spherical aberration were significantly increased in FS-LASIK group at different postoperative time points (all at P<0.05). Compared with before surgery, postoperative total HOA of the anterior corneal surface and spherical aberration at different postoperative time points were significantly increased in both groups (all at P<0.05). In both groups, the 12-month postoperative corneal spherical aberration was significantly reduced in comparison with the 1- and 3-month postoperative ones (all at P<0.05). There was a significant difference in coma between before and after surgery ( Ftime=30.829, P<0.01). Compared with before surgery, the postoperative coma was significantly increased at different time points in both groups (all at P<0.05). Conclusions:Both FS-LASIK and SMILE increase the HOA of the anterior corneal surface and the whole cornea.Compared with FS-LASIK, SMILE introduces less HOA of the anterior corneal surface and the whole cornea as well as spherical aberrations.

Objective : To study the guidance effects of fibroblast growth factor 3 ( FGF3) on the prethalamic γ⁃aminobutyric acid (GABA) inhibitory axons, and to explore the effect of FGF3 on the formation of thalamic axonal network. Methods : Expression and localization of FGF3 and prethalamic GABA marker gene in chicken embryonic diencephalon were detected by immunofluorescence. Early orientation of GABA axons was tracked by DiI. Three⁃dimensional gel co⁃culture experiment was carried out to investigate guidance effects of FGF3 on early prethalamic GABA inhibitory axons. Results : Prethalamic GABA cells were adjacent to the FGF3 + hypothalamas, located above the hypothalamus. DiI tracing experiments revealed that prethalamic GABA inhibitory axons had already extended into the thalamus at E6. Compared with the blank control group, FGF3 not only significantly promoted the growth of prethalamic GABA inhibitory nerve fibers in the prethalamus, but also repelled the newborn prethalamic axons to the dorsal thalamus. The number of prethalamic axons was significantly less in proximal section (towards FGF3 beads) than that in distal section (away from FGF3 beads) (P < 0. 01) . Moreover, the guidance effects of FGF3 on prethalamic axons could be blocked by the FGF pathway inhibitor SU5402. Conclusion FGF3, an axon guidance molecule expressed in hypothalamus, exerts guidance effects on the pathway selection of adjacent prethalamic GABA inhibitory nerve fibers.

ObjectiveTo apply ultrasonography to quantitatively evaluate the structure and biomechanical properties of gastrocnemius muscle in children with spastic cerebral palsy. MethodsFrom December, 2020 to December, 2021, 36 children with spastic diplegia or hemiplegia were selected as experimental group, and other 30 healthy children matched age and gender were as control group during the same period. All the subjects were measured muscle thickness (MT), muscle fiber length (FL), pinnate angle (PA) and shear wave velocity (SWV) with two-dimensional ultrasound imaging and shear wave elastography on the medial gastrocnemius of the affected side (hemiplegia), more serious side (diplegia) or random side (control group), while the gastrocnemius muscle tone and gross motor function of the experimental group were assessed with modified Ashworth Scale (MAS) and Gross Motor Function Measure (GMFM). ResultsMT and FL were less in the experimental group than in the control group (|t| > 3.937, P < 0.001), while PA and SWV were more (|t| > 6.105, P < 0.001). MT and FL positively correlated to GMFM score (r > 0.391, P < 0.05), while SWV positively correlated to MAS score (r = 0.734, P < 0.001). ConclusionUltrasonography can be used to quantitatively evaluate the structure and stiffness of gastrocnemius muscle for children with spastic cerebral palsy.

Objective:To develop a Risk Assessment Index System (RAIS) on HIV infection among young students based on Delphi method and to provide individual HIV infection risk assessment, targeted prevention and control measures.Methods:Delphi method was applied to determine the index system and weight of the assessment tool through three rounds of expert consultation and overall consideration of opinions and suggestions from 19 experts.Results:The positivity coefficients of three rounds of expert consultation were 100%. The authority coefficient of experts was between 0.887 and 0.945. The Kendall's W coefficients through first, second and third round specialist consultation was 0.379, 0.329 and 0.248, respectively (all P<0.001). The coefficients of variation in the third round were all less than 0.25, indicating that experts' opinion tend to be consistent and the results are highly reliable. The HIV infection risk assessment index system among young students consisted of 7 first grade indices and 54 second grade indices, of which weight was calculated. Conclusions:The RAIS on HIV infection for young students was initially established based on Delphi method, and could be used in the development of HIV infection risk assessment tools for personalized prevention and intervention among young students. However, the reliability, validity and effect of this assessment index system need to be further evaluated.

Objective:To explore the difference of sexual health characteristics and demands in students in different groups, and provide the basis for targeted sexual health eduction for AIDS prevention in young students.Methods:A survey was conducted based on the requirement of health education about sexual health and AIDS prevention in young students by the education department of Guangdong province. A two-step cluster analysis was performed on the survey data obtained by convenient sampling, the variables and number of clusters included were determined by combination of analysis results and professional knowledge. The demographic characteristics, the content and form of sexual health education needed were compared among different groups.Results:Survey data of 3 884 students were collected, and six variables were used for classification: cognition or occurrence masturbation, sexual behavior, frequency of sexual information acquisition, number of acceptable sex partners and AIDS knowledge awareness rate. By these variables, the students were classified into three levels of risk groups: high risk group (46.6%), medium risk group (39.9%) and low risk group (13.5%). As for demographic characteristics, high risk group, with a median age of 19 years, had the highest proportions of boys (65.9%), students with non-heterosexuality orientation (15.2%), urban residents (58.2%), only children (30.8%) and undergraduates (54.7%). Medium risk group, with a median age of 19 years, had the highest proportions of girls (82.7%) and vocational college students (34.0%). Low risk group, with a median age of 18 years, had the highest proportions of rural residents (52.4%), non-only child (80.6%), senior high school students (41.3%), non-boarding students (17.5%) and students without internship and part-time job experience (43.2%). In terms of health education demands, high risk group had a higher demand of information about self-identity, sexual safety, sexual decision making, contraception, abortion, and sexually transmitted disease or AIDS prevention. Medium risk group paid more attention to value on love and marriage, sexual assault. Low risk group showed a higher demand of adolescent physiology knowledge. Compared with low risk group, high risk group had a higher demand of peer education, Internet/multimedia, anonymous counseling and other forms of sexual health education. The differences were significant.Conclusion:The characteristics, sexual knowledge awareness, attitude and behavior, and health education demands of young students in different groups are different, so health education materials and methods should be developed according to the characteristics of different groups to enhance the acceptance and enthusiasm of students and improve the quality of sexual health education.

Objective:To evaluate the effect of "self-categorization" on decision of health preference and the influence of self-categorized deviation in knowledge, attitude and practice (KAP) on the willingness of seeking help for sexual health among young students.Methods:From March to April 2019, young students who used a WeChat applet for sexual health and HIV infection risk assessment, which is called "Detective Bear" were recruited and investigated. According to the consistency between the self-categorization of KAP for sexual health and the systematic categorization from their honest answers, the participants were allocated into three groups: consistent, low or high status, according to their judgment on sexual information acquisition, sexual attitude, and the actual number of sexual experiences. Logistic regression was used to analyze the differences in the willingness to seek help for sexual health problems between the three groups.Results:2 009 students with an average age of (19.2±1.1) were included. 54.7% (1 099/2 009) were female, and 98.4% (1 976/2 009) were college, undergraduate or postgraduate students. 49.0% (984/2 009) were in the consistent group, 10.9% (219/2 009) had a lower self-categorization, 40.1% (806/2 009) had a higher self-categorization. Compared with the consistent group, students with lower self-categorization of KAP for sexual health were less likely to assess HIV voluntary counseling and testing (a OR=0.65, 95% CI: 0.43-0.99). However, students with higher self-categorization seemed to dislike seeking help for sexually transmitted diseases (a OR=0.76, 95% CI: 0.59-0.98). Conclusions:Deviation in self-categorization of KAP for sexual health will reduce the young students' willingness to seek help for related problems. Especially those with lower self-categorization, lack of risk consciousness, and refuse to assess counseling and testing may increase the HIV/AIDS epidemic among this population. It is necessary to strengthen the capacity of self-assessment for young students while promoting sex education.
