Objective: To investigate the association between uric acid level and elevated blood pressure among children and adolescents in Guangzhou, so as to provide a scientific basis for prevention and control of hypertension in the pediatric population. Methods: From March to December 2019, using stratified cluster random sampling, 3 626 children and adolescents aged 6-17 years without elevated blood pressure at baseline were recruited from 6 primary and secondary schools in Guangzhou. Serum uric acid levels were measured at baseline, and divided into four groups ( Q1-Q 4) based on age and sex specific quartiles for analyses. Two waves of follow up were carried out from October 2020 to May 2021 and from October 2021 to May 2022, respectively. Multilevel robust Poisson regression was used to evaluate the association between uric acid level and elevated blood pressure among children and adolescents. The additive interaction between high uric acid level and sugar sweetened beverage (SSB) intake on elevated blood pressure was assessed by stratification analysis and calculation of the relative excess risk due to interaction (RERI). Results: A total of 1 131 new cases of elevated blood pressure were identified during the two follow ups, with an incidence density of 130.5 cases 1 000 person years. Multilevel robust Poisson regression analysis showed that after adjusting for confounders such as gender, age and annual family income, compared with those in the uric acid Q 1 level, the risk of elevated blood pressure in individuals in the Q 4 level increased by 25% ( RR=1.25, 95%CI =1.08-1.44), and the risk of elevated systolic blood pressure increased by 20% ( RR=1.20, 95%CI =1.05-1.36) (both P <0.05); no statistical association was observed between uric acid and elevated diastolic blood pressure (all P >0.05). In the stratified analysis, the statistical associations of uric acid Q 4 level with elevated blood pressure ( RR=1.34, 95%CI =1.13-1.58) and elevated systolic blood pressure ( RR=1.33, 95%CI =1.14-1.55) were only observed in the group with SSB intake ≥ 250 mL/week (both P <0.05). The RERI values for the effect of uric acid Q 4 and Q 3 levels with SSB intake ≥ 250 mL/week on elevated systolic and diastolic blood pressure were 0.29 and 0.44 (both P <0.05). Conclusions High uric acid level is a risk factor for elevated blood pressure among children and adolescents, with a predominant effect on systolic blood pressure. High uric acid level and SSB intake synergistically promote the increase of blood pressure of children and adolescents.

Objective:To investigate the clinical efficacy of repetitive transcranial magnetic stimulation (rTMS) versus functional electrical stimulation (FES) in the treatment of post-stroke complex regional pain syndrome. Methods:The randomized controlled study included 60 patients with post-stroke complex regional pain syndrome who received treatment at the Wenzhou TCM Hospital of Zhejiang Chinese Medical University from July 2021 to February 2023. These patients were divided into an rTMS group ( n = 30) and an FES group ( n = 30) using a random number table method. Patients in the rTMS group were treated with rTMS, while those in the FES group were treated with FES. All treatments were performed once daily for 8 consecutive weeks. The clinical efficacy, total active movement score of the fingers, Fugl-Meyer assessment scale score, Activity of Daily Living score, modified Barthel Index score, shoulder joint range of motion, and safety were compared between the two groups. Results:The total response rate in the FES group was 86.7% (26/30), which was significantly higher than 83.3% (25/30) in the rTMS group ( Z = 0.09, P = 0.93). After treatment, there were no significant differences between the two groups in terms of total active movement score of the fingers and Fugl-Meyer assessment scale score ( P = 0.244, 0.262). No significant differences were found between the two groups in MBI score and ADL score (both P > 0.05). There was also no significant difference in shoulder joint range of motion between the two groups ( P > 0.05). Conclusion:Both rTMS and FES are highly effective for post-stroke complex regional pain syndrome. They can improve upper limb function, enhance daily living abilities, and remodel neurological functions of the brain.

Kabuki syndrome (MIM 147920) is an autosomal dominant rare disease featured with multiple malformations and mental retardation. The main clinical manifestations of Kabuki syndrome are characteristic facial features, skeletal abnormalities, dermatoglyphic abnormalities, postpartum growth retardation, mild to moderate mental retardation, as well as other structural and functional abnormalities that may involve multiple systems. The establishment of diagnosis needs to be combined with clinical phenotype and the discovery of pathogenic mutation. Compared with the abundant descriptions and records of genotype-phenotype of postpartum patients, few prenatal diagnosis cases of Kabuki syndrome had been reported, which partially result from lacking the knowledge of its phenotype in fetuses that might suggest the diagnosis. This report performed comprehensive prenatal examinations to identify a fetus's etiology with multiple structural anomalies characterized by ascites, thickening of local skin, and cardiac abnormalities. We ruled out intrauterine infection, thalassemia, and chromosome abnormality by corresponding tests. Finally, trio whole-exome sequencing revealed a de novo heterozygous variation c.15641g > A (p.r5214h) in exon 48 of the KMT2D gene was the fetus's genetic pathogeny causing Kabuki syndrome. This result suggests that Kabuki syndrome should be in the suspected etiology list for prenatal hydrops/ascites. Our study confirmed that prenatal whole-exome sequencing is an efficient tool for diagnosing fetal abnormalities, and a multidisciplinary team is necessary for providing pregnancy guidance to patients.

Objective To investigate the therapeutic effect of different combinations of acupuncture and robot training on balance function in patients with Parkinson's disease.Methods A total of 60 patients with Parkinson's disease admitted to Wenzhou Traditional Medicine Hospital from October 2020 to October 2022 were randomly divided into two groups.Group A was given robot training after receiving acupuncture of Baihui and Dazhui points.Group B received those treatments simultaneously.And the balance function of patients was evaluated by Berg balance scale(BBS),Morse fall assessment scale(MFS)and timed up and go test(TUGT).Results In the intra-group comparison,TUGT in group A was significantly improved after 4 weeks of treatment(P<0.01);MFS and TUGT in group B were significantly improved compared with those before treatment(P<0.01).After 8 weeks of treatment,BBS and TUGT in group A were significantly improved compared with those before treatment(P<0.01);BBS,MFS and TUGT in group B were significantly improved compared with those before treatment(P<0.01).At the 12th week,BBS,MFS and TUGT in both groups were significantly improved compared with those before treatment(P<0.01).Comparison between groups:BBS,MFS and TUGT in group B were not significantly different from those in group A at 4 weeks of treatment(P>0.05);After 8 weeks of treatment,MFS in group B was significantly improved compared with that in group A(P<0.05),BBS and TUGT were better than that in group A without significant difference(P>0.05).After 12 weeks of treatment,BBS(P<0.01),MFS(P<0.01)and TUGT(P<0.05)in group B were significantly improved compared with group A.Conclusion Acupuncture at Baihui and Dazhui points combined with robot training simultaneously can improve the balance function and anti-falling ability of Parkinson's disease.

Objective: In view of the difficulty of the shortage of new coronavirus nucleal acid test in the early COVID-19 outbreak, to explore the application value of chest CT in screening COVID-19 patients. Methods: Retrospective analysis was performed on the data of patients with fever who received chest CT and new coronavirus nucleal acid test during January 25, 2020 to February 2, 2020 in Zhongnan Hospital of Wuhan University. A total of 587 patients were enrolled, including 290 males and 297 females, aged from 11.0 to 96.0 (51.3±17.1) years old. Take the nucleic acid test results as the gold standard, the sensitivity, specificity and rate of missed diagnosis of CT screening COVID-19 were calculated. Results: Among the 587 patients, there were 433 positive cases (73.8%, 433/587) and 154 negative cases (26.2%, 154/587) of novel coronavirus nucleic acid test. Using CT screening, 494 cases (84.2%, 494/587) were positive and 93 cases (15.8%, 93/587) were negative. The sensitivity of CT screening COVID-19 was 97.7% (423/433), specificity was 53.9% (83/154) and rate of missed diagnosis was 2.3% (10/433). Conclusions In the early COVID-19 outbreak, CT screening has the advantages of high sensitivity and low rate of missed diagnosis of COVID-19, which can compensate for the shortage of new coronavirus nucleal acid test and can be used as the basis for rapid screening for early prevention and control of COVID-19 outbreak.

Objective To discuss the safety and the application of the self-designed multifunctional inflatable pelvis and hip-joint fixator (MIPHF) in damage control in pelvic fracture patients.Methods The MIPHF was subjected to pressure test and quality inspection.From September 2016 to June 2017,61 pelvic-fracture patients were treated with our self-designed MIPHF as pre-hospital first-aid care according to the concept of damage control orthopedics (DCO) (MIPHF group).The control group consisted of 69 pelvic-fracture patients who had not received pre-hospital first-aid care with the self-designed MIPHF from December 2015 to August 2016.There were no statistically significant differences between the two groups in gender,age,types of pelvic fracture,and preoperative injure severity score (ISS).The study compared the two groups for the case fatality rate,volume of blood transfused during surgeries,early complication rates,fracture reduction (Matta standards),and long-term efficacy (Cole scores).Results The pressure test showed that the MIPHF had a good fixation effect on the pelvis.And the quality inspection showed that the material used for the MIPHF was in line with national standards and the safety was guaranteed.The MIPHF group had 1 death (1.6％) and the control group had 8 deaths (11.6％),which was a significant difference (x2=4.979,P=0.026).All survival patients in both groups were followed up.The MIPHF group (61 cases) received 3.0 to 18.0 months follow-up,with an average of 9.0 months.And the control group (69 cases) had 18.0 to 30.0 months follow-up,with an average of 21.9 months.In the MIPHF group,23 cases were treated conservatively,and 37 cases were treated with surgery.Among them,3 cases were fixed with external fixator,20 cases with anterior open reduction and internal fixation,9 cases with posterior open reduction and internal fixation,and 5 cases with combined anterior and posterior fixation.The timing of surgery was 1 to 20 days after injury,with an average of 4.1 days.The volume of blood transfused in the MIPHF group during surgery was 200 to 1500 ml,with an average of 628.6 ml.In the control group,27 patients were treated conservatively,and 42 patients were treated with surgery.Among them,2 cases were fixed with external fixator,24 cases with anterior open reduction and internal fixation,10 cases with posterior open reduction and internal fixation,and 6 cases with combined anterior and posterior fixation.The timing of surgery was 1 to 15 days after injury,with an average of 3.l days.The volume of blood transfused in the control group during surgery was 200 to 4000 ml,with an average of 1 707.1 ml.There was a significant difference between the two groups in intraoperative blood transfusion(Z=-2.330,P=0.020).The MIPHF group had 10 (16.4％) cases of early serious complications and the control group had 22 (31.9％) cases,which had a significant difference (x2=4.187,P=0.041).According to the criteria proposed by Matta et al.,the good rate of results for treating fractures was 82.0％ in the MIPHF group and 60.9％ in the control group,which got a significant difference (x2=6.967,P=0.008).The MIPHF group and the control group also differed significantly in their mean long-term Cole scores (27.2±4.0 versus 25.1 ±5.6,t=2.457,P=0.015).Conclusion MIPHF,which reflects the DCO concept,may be recommended as pre-hospital first-aid care for patients with pelvic fracture because it can lessen bleeding and prevent secondary pelvic injury,thus reduce case fatality rate and the incidence of complications.It can also improve the success rate of treating pelvic fracture,which will positively affect long-term outcomes.

Objective To explore the curative effect of deep-brain magnetic stimulation (DMS) on learned helplessness behavior in the chronic restrained stress (CRS) rat model. Methods Twenty-nine Sprague-Dawley rats were randomly divided into control group (n=8) and CRS group (n=21). CRS group was exerted chronic restrained stress, while the control group did not receive any stress, for three weeks. Then learned helplessness behavior was tested using Forced Swimming Test (FST) and the hopeless rats of the CRS group were divided ran-domly into sham group (n=6), DMS group (n=8) and citalopram group (n=7), that received corresponding treatment respectively. They were evaluated with FST again after one-week treatment. Results The immobile time in FST was longer in CRS group than in the control group after three-week stress (F=11.260, P=0.002). After one-week treatment, no significant improvement was found in the citalopram group (F=1.565, P=0.235), however, the immobile time in DMS group decreased (F=6.277, P=0.025), and was shorter than that in the sham group (F=5.560, P=0.036). Conclusion CRS could result in learned helplessness behavior, which could be alleviated with one-week DMS.

OBJECTIVETo understood the accuracy of oral fluid-based rapid HIV self-testing among men who have sex with men (MSM) and related factors.

METHODSSurvey was conducted among MSM selected through non-probability sampling to evaluate the quality of their rapid HIV self-testing, and related information was analyzed.

RESULTSThe most MSM were aged 21-30 years (57.0%). Among them, 45.7% had educational level of college or above, 78.5% were unmarried, 59.3% were casual laborers. The overall accuracy rate of oral fluid based self-testing was 95.0%, the handling of"inserting test paper into tube as indicated by arrow on it"had the highest accuracy rate (98.0%), and the handling of"gently upsetting tube for 3 times"had lowest accuracy rate (65.0%); Chi-square analysis showed that educational level, no touch with middle part of test paper, whether reading the instruction carefully, whether understanding the instruction and inserting test paper into tube as indicated by the arrow on it were associated with the accuracy of oral fluid-based rapid HIV self-testing, (P<0.05). Multivariate logistic regression analysis indicated that educational level, no touch with middle part of test paper and understanding instructions were associated with the accuracy of oral fluid-based rapid HIV self-testing.

CONCLUSIONSThe accuracy of oral fluid-based rapid HIV self-testing was high among MSM, the accuracy varied with the educational level of the MSM. Touch with the middle part of test paper or not and understanding the instructions or not might influence the accuracy of the self-testing.

Objective To explore the effect of intracerebroventricular injection of AR-M1896, a galanin receptor 2 agonist, on depres-sion-like behavior in rat chronic mild stress (CMS) model. Methods 48 Sprague-Dawley rats were randomly assigned into control group, CMS group, CMS artificial cerebrospinal fluid (aCSF) group and CMS AR-M1896 group equally. The control group received no interven-tion, and the other groups were established chronic mild stress model. After six-week of stress, forced swim test and sucrose preference test were conducted to identify the CMS rats. AR-M1896 or aCSF was injected into the lateral ventricle of CMS AR-M1896 group and CMS aC-SF group, respectively. The immobility time and climbing time in the forced swim test were analysed, and the sucrose consumption percent-age in the sucrose preference test was measured. Results The immobility time decreased (F=11.998, P<0.01), climbing time increased (F=8.268, P<0.05), and the sucrose consumption percentage increased (F=10.352, P<0.01) in CMS AR-M1896 group, compared with CMS aC-SF group. Conclusion Intracerebroventricular administration of galanin receptor 2 agonist AR-M1896 is effective on depression in CMS model rats.
