Indocyanine green fluorescence imaging technique is a visualization imaging technique based on indocyanine green fluorescent dyes. According to different imaging principles, it can be classified into intravenous injection of indocyanine green fluorescence imaging technique and indocyanine green super-selective transarterial embolization fluorescence imaging technique. This article provides a detailed overview of current major studies based on these two techniques. Its application in laparoscopic partial nephrectomy can shorten the warm ischemia time and reduce postoperative renal function injury. It is especially applicable for special types of renal tumors in complex locations, such as complete endophytic tumors and tumors in the renal hilum area. However, there is still no standardized operation specifications and evaluation criteria for its application. Focuses on the aforementioned topics and bases on emerging clinical evidence, this article reviews the principles, injection methods, safety, and clinical research advances and application linitations of indocyanine green fluorescence imaging technique in laparoscopic partial nephrectomy.

Objective : To explore the advantages of static navigation in locating calcified root canal therapy, and to provide reference for clinical diagnosis and treatment of calcified teeth. Methods: A case of acute periapical periodontitis of anterior teeth with full-length calcification of root canal was reported. A lingual minimally invasive approach was used as a conservative method of controlling the infection of teeth and preserving the incisors through the digital guide plate. The diagnosis and treatment of this type of case were analyzed retrospectively with reference to the literature. Results: One patient complained that the pain of left anterior teeth was aggravated for 2 days. After examination, he was diagnosed with acute periapical periodontitis of 21 teeth with total root canal calcification. With the assistance of static navigation, the root canal was located after 10 minutes, the calcification was dredged for 15 minutes, and the acute pain symptoms of the patient were relieved that day. After one year of follow-up, there was no discomfort in the teeth, and the range of low-density shadow in the apical film was reduced. After 3 years of follow-up, there was no discomfort in the teeth, and the low-density shadow of the apical root was further reduced by apical film examination. As shown by the results of the literature review, static navigation technology is advantageous because the success rate of dredging calcified root canals is neither associated with the operator’s treatment experience nor the use of microscope and ultrasonic equipment. Regardless of the degree of calcification, this method can significantly reduce the iatrogenic risk, but it is closely related to the accuracy and stability of the guide plate. However, this method is not suitable for calcified teeth with calcification under root canal curvature and limited operating space. Cone-beam computed tomography (CBCT) is recommended to locate calcified root canals, and the imaging quality is an important factor that affects the correct preoperative planning. When performing static navigation endodontic treatment, thermal damage can be reduced by selecting a drill with a small diameter that matches the guide ring and cooling the drill with frozen irrigation solution. Conclusion Static navigation-assisted treatment of calcified root canals is accurate and minimally invasive, which reduces clinical treatment time, preserves the lingual approach at the incisal ridge to further ensure the integrity of teeth, and ensures the long-term preservation of affected teeth.

Objective:To investigate the genetic causes of fetuses with abnormal nasal bone development in early pregnancy.Methods:A retrospective study was conducted which involved 422 cases of singleton pregnancies with nasal bone development abnormalities indicated by ultrasound screening at 11 to 13 weeks and 6 days of gestation, who underwent chorionic villus sampling for prenatal diagnosis at the Prenatal Diagnosis and Genetic Center, Maternity & Child Health Hospital of Guangxi Zhuang Autonomous Region from January 2015 to May 2023. All cases underwent chromosomal karyotype analysis and single nucleotide polymorphism array (SNP-array) analysis. Based on whether other abnormal ultrasound indicators were present, the cases were divided into isolated (175 cases) and non-isolated groups (247 cases). The results of invasive prenatal diagnosis, distribution of chromosomal abnormalities, detection of copy number variation (CNV) in fetuses with nasal bone development abnormalities, the relationship between maternal age, number of abnormal ultrasound indicators and chromosomal abnormalities, and pregnancy outcomes were analyzed. Statistical analysis was performed using the Chi-square test (continuity correction Chi-square test or Fisher's exact test). Results:(1) Among the 422 cases, 262 cases (62.1%) showed no abnormalities with both detection techniques; 160 cases had abnormalities, including 145 cases (34.4%) had consistent abnormal results and types of abnormalies with the two techniques; two cases (0.5%) had chromosomal translocations detected by karyotype analysis but not by SNP-array analysis; 13 cases (3.1%) had no abnormalities detected by karyotype analysis but had abnormal SNP-array results. This study's overall detection rate of chromosomal abnormalities was 37.9% (160/422), with an additional detection rate of 4.7% (13/275) using SNP-array technology. (2) Among the 160 cases of chromosomal abnormalities, there were 140 cases of aneuploidy, 18 cases of CNV, and two cases of chromosomal translocation. The overall detection rate of chromosomal abnormalities and the detection of aneuploidy, and pathogenic CNV in the non-isolated group was higher than that in the isolated group [74.3% (130/175) vs. 12.1% (30/247), χ2=168.02; 68.0% (119/175) vs. 8.5% (21/247), χ2=163.56; 5.7% (10/175) vs. 0.8% (2/247), χ2=4.74; all P<0.05]. Eighteen cases of CNV were detected using SNP-array technology, including eight cases in the isolated group and ten cases in the non-isolated group. (3) The age of the 422 pregnant women was (33.1±5.4) years. In both isolated and non-isolated groups, the detection rate of chromosomal abnormalities was higher in women of advanced age (expected delivery age ≥35 years) than those not [isolated group: 20.0% (17/85) vs. 8.6% (14/162), χ2=6.55; non-isolated group: 82.1% (69/84) vs. 65.9% (60/91), χ2=5.92; both P=0.010]; regardless of maternal age, the detection rate of chromosomal abnormalities in the non-isolated group was significantly higher than that in the isolated group ( χ2 were 65.28 and 92.42, respectively, both P<0.001). (4) In the non-isolated group, the detection rates of chromosomal abnormalities were 69.0% (78/113) and 83.9% (52/62) when nasal bone abnormalities were combined with one or more other abnormal ultrasound indicators, respectively. When combined with increased nuchal translucency, the detection rate of fetal chromosomal abnormalities was 73.2% (71/97), higher than the detection rate when combined with other single indicators (7/16) ( χ2=5.57, P=0.020). (5) Among the 262 cases with negative karyotype analysis and SNP-array results, 241 cases (92.0%) resulted in live births, with a gestational age at delivery of 39 weeks (32-41 weeks); 12 cases (4.6%) resulted in induced labor, five cases (1.9%) resulted in miscarriage, and four cases (1.5%) were lost to follow-up. The live birth rate in the isolated group was higher than that in the non-isolated group [86.9% (213/245) vs. 20.2% (35/173), χ2=187.00, P<0.001]. Conclusions:Fetuses with nasal bone developmental abnormalities in early pregnancy have a higher detection rate of chromosomal abnormalities and CNV. Invasive prenatal diagnosis is recommended for cases of nasal bone developmental abnormalities in early pregnancy, whether isolated or non-isolated. When combined with other abnormal indicators, the genetic etiology of the fetus is more complex, and detailed genetic counseling should be provided to the patient.

Objective:To investigate genetic findings and pregnancy outcomes in fetuses with omphalocele.Methods:This retrospective study analyzed data from 502 fetuses with prenatally diagnosed omphalocele who underwent genetic testing at Guangzhou Women and Children's Medical Center and Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region between January 2014 and March 2024. Testing methods included karyotyping, chromosomal microarray analysis (CMA), methylation-specific multiplex ligation-dependent probe amplification, and whole-exome sequencing (WES). Cases were categorized as non-isolated ( n=340) or isolated ( n=162) based on ultrasound findings. Differences in genetic abnormality detection rates and pregnancy outcomes were analyzed using Mann-Whitney U test, independent samples t-test, and Chi-square test (or Fisher's exact test). Results:Among 502 fetuses, karyotyping plus CMA detected chromosomal abnormalities in 223 cases (44.4%, 223/502), including trisomy 18 (57.0%, 127/223) and trisomy 13 (23.3%, 52/223). CMA additionally identified nine pathogenic copy number variations (1.8%, 9/502) and five uniparental disomies (1.0%, 5/502), increasing the total diagnostic yield from 44.4% to 47.2%. The genetic abnormality rate was significantly lower in isolated (14.8%, 24/162) versus non-isolated omphalocele (64.7%, 220/340) ( χ2=109.34, P<0.001). WES detected variants in nine of 16 karyotype/CMA-negative cases, including five pathogenic variants involving PIK3CA and CDKN1C. Eight imprinting disorders (1.6%, 8/502) were identified, including five Beckwith-Wiedemann syndrome cases. Among 499 cases with follow-up, 401 (80.4%, 401/499) underwent pregnancy termination. Live birth rate was higher in isolated versus non-isolated groups [42.5% (69/162) vs. 8.5% (29/340), χ2=77.67, P<0.001]. Three cases were lost to follow-up. The one-year survival rate was 93.9% (92/98) in live-born infants. Conclusion:Aneuploidy (particularly trisomy 18) is the primary genetic etiology of omphalocele. CMA and WES significantly improve diagnostic yield. Isolated omphalocele has a more favorable prognosis, while non-isolated cases show significantly higher genetic abnormality rates. A stratified testing strategy is recommended: karyotyping plus CMA for isolated cases and prioritization of WES for multiple anomalies.

Methods The data of death surveillance and demography were collected. The causes of death were classified and coded according to ICD-10. The crude mortality, standardized mortality and potential years of life lost were calculated. Results From 2019 to 2020, 910 people died in Pingshan district.The average age of death was 64.94(47.06 - 82.34) years, the crude mortality was 102.04/100 000, the standardized mortality was 263.97/100 000, and the average life expectancy was 86.00 years. 558 men died and 352 women died , the crude mortality were 113.72/100 000 and 87.76 /100 000 , the standardized mortality rate 313.05/100 000 and 211.97/100 000 ; the average life expectancy were 84.66 years and 87.55 years . The crude mortality of male was higher than that of female (χ²=14.594, P<0.001). The standardized mortality of men was also higher than that of women. The top three causes of death in the whole population, men and women were circulatory system diseases, malignant tumors, diseases and injury from high to low. And the top three diseases with standardized potential life lost years and standardized potential life lost rate from high to low were injury, circulatory system diseases and malignant tumors. Conclusion Circulatory system diseases, malignant tumors, injury are the main causes of death and the three kinds of diseases with the heaviest disease burden in Pingshan District of Shenzhen city. Men are the key population for prevention and control. The prevention and control of the above three kinds of diseases should be done to reduce the mortality of local population.

OBJECTIVES: To investigate the differences in non-suicidal self-injury (NSSI) behaviors between only-child and non-only-child adolescents with mood disorders. METHODS: A three-stage sampling method was used to perform a cross-sectional survey of 529 adolescents, aged 12-18 years, who had mood disorders and NSSI behaviors. These adolescents were sampled from the outpatient service of 20 mental hospitals in 9 provinces of China from August to November 2020. A self-made questionnaire was used to collect general demographic data. The Functional Assessment of Self-Mutilation, Beck Scale for Suicide Ideation, Kessler Psychological Distress Scale, Stress Mindset Measure-General, Multidimensional Scale of Perceived Social Support, Multidimensional Students' Life Satisfaction Scales, and Rosenberg Self-Esteem Scale were used to collect the information on self-injury behaviors and psychological factors in these adolescents. RESULTS: A total of 529 adolescents with mood disorders and NSSI behaviors were surveyed, among whom 375 were only-child adolescents and 154 were non-only-child adolescents. Compared with the non-only-child group, the only-child group had a significantly higher total score of Functional Assessment of Self-Mutilation (P<0.05) .The type and frequency of self-injury in the only-child group were significantly higher than those in the non-only-child group (P<0.05). Psychological analysis showed that compared with the non-only-child group, the only-child group had a significantly lower score of self-esteem (P<0.05) and significantly higher scores of psychological distress and depressive symptoms (P<0.05). The multiple linear regression analysis showed that the score of suicidal ideation was positively correlated with the frequency of NSSI behaviors in both only-child and non-only-child adolescents with mood disorders (P<0.05); in the only-child adolescents, the level of self-esteem was negatively correlated with the frequency of NSSI behaviors (P<0.05), and the score of stress perception was positively correlated with the frequency of NSSI behaviors (P<0.05); in the non-only-child adolescents, the score of anxious emotion was positively correlated with the frequency of NSSI behaviors (P<0.05). CONCLUSIONS Among the adolescents with mood disorders and NSSI behaviors, the only-child adolescents tend to have a higher frequency of self-injury and poorer mental health, and therefore, the only-child adolescents with mood disorders and NSSI behaviors need more attention.

OBJECTIVETo understand the relationships between CDH13 (T-cadherin) genetic polymorphisms, adiponectin levels and ischemic stroke, and possible interactions between CDH13 polymorphisms and other risk factors.

METHODSWe recruited 342 Chinese ischemic stroke sib pairs. We genotyped rs4783244 and rs7193788 on CDH13 using time-of-flight mass spectrometry genotyping technology and measured total and high-molecular weight (HMW) adiponectin levels. We investigated associations between SNPs and ischemic stroke, and interactions between SNPs and other risk factors using multi-level mixed-effects regression model.

RESULTSIn individuals without ischemic stroke, CDH13 rs4783244 was associated with total adiponectin levels (per T: Coef = -0.257, P = 0.001). CDH13 rs7193788 was associated with total adiponectin levels (per A: Coef = -0.221, P = 0.001) and HMW adiponectin levels (per A: Coef = -0.163, P = 0.003). rs7193788 was significantly associated with ischemic stroke (GA/AA vs. GG: OR = 1.55, 95% CI: 1.07 to 2.24, P = 0.020) after Bonferroni correction (α = 0.025). There was an interaction between rs7193788 and diabetes (P = 0.036). Compared to diabetes-free individuals with rs7193788 GG genotype, diabetes patients with rs7193788 GA/AA genotypes had higher risks for ischemic stroke (OR = 2.64, 95% CI: 1.58-4.40, P < 0.001).

CONCLUSIONCDH13 genetic polymorphisms are associated with adiponectin levels and ischemic stroke. An interaction is found between CDH13 SNP and diabetes for ischemic stroke.
