Renal tumor scoring systems can describe the anatomical characteristics of renal tumors. It is an important standard to evaluate the surgical complexity and to evaluate the surgical complexity and feasibility of partial nephrectomy. Scholars at home and abroad have established various scoring systems based on different anatomical parameters，such as R.E.N.A.L.，PADUA，C-Index，which are used to guide the clinical selection of surgical modalities，and predict perioperative complications and prognosis. In this paper，various scoring systems are grouped into three major categories according to their functions：prediction of surgical complexity，prediction of complications，and prediction of prognosis. The contents，characteristics and clinical application value of various renal tumor scoring systems are introduced in detail to guide urologists，enhance their surgical decision-making ability，and improve the clinical outcomes.

ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Objective To evaluate the efficacy and safety of modified pelvic floor reconstruction in non-nerve-sparing robot-assisted radical prostatectomy (NNS RARP) for improving postoperative urinary control. Methods A retrospective analysis was conducted on the clinical data of 79 prostate cancer patients who underwent NNS RARP at Tangdu Hospital during Jan.2020 and Dec.2023, including 29 in the reconstruction group, and 50 in the non-reconstruction group. The baseline characteristics including age, body mass index, prostate-specific antigen (PSA) level, clinical stage, prostate volume, and biopsy Gleason score, and perioperative indexes including operation time, intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins were compared between the two groups. Additionally, urinary continence function was assessed before operation and 1,3,6, and 12 months after operation using the international consultation on incontinence questionnaire-short form (ICIQ-SF) and the incontinence quality of life questionnaire score (I-QoL). Results No statistically significant differences were observed in the baseline characteristics between the two groups (P>0.05). The operation time was significantly longer in the reconstruction group than in the non-reconstruction group [ (110.24±15.08) min vs. (101.80±9.89) min, P=0.010]. There were no significant differences in intraoperative blood loss, catheter indwelling time, complication rate, and positive rate of surgical margins between the two groups (P>0.05). The reconstruction group demonstrated significantly lower ICIQ-SF scores at 1 month [ (10.17±2.16) vs. (11.56±1.66), P=0.002],3 months [ (7.62±1.29) vs. (9.52±1.80), P<0.001], and 6 months postoperatively [ (4.93±1.22) vs. (6.18± 1.67), P=0.001]compared to the non-reconstruction group (adjusted P<0.0125). Conversely, the I-QoL scores were significantly higher in the reconstruction group at 1 month [ (73.32±10.30) vs. (63.88±9.55), P<0.001]and 3 months postoperatively [ (78.91±4.82) vs. (75.66±5.17), P=0.007] (adjusted P<0.0125). However, no significant differences were found in ICIQ-SF or I-QoL scores between the two groups preoperatively and 12 months postoperatively (adjusted P>0.0125). Conclusion The application of modified pelvic floor reconstruction technique in NNS RARP is safe and feasible. Although it slightly prolongs the operation time, it does not increase surgical risks; instead, it effectively promotes early recovery of postoperative urinary continence, thereby significantly enhancing patients'quality of life.

【Objective】 To explore the factors influencing erectile dysfunction (ED) in male patients after renal transplantation, so as to provide basis for the prevention and treatment of this disease. 【Methods】 Kidney transplant recipients followed up in the Kidney Transplant Clinic of Xijing Hospital during Sep.1, 2022 and May 1, 2023 were selected as the study objects.Questionnaires were distributed, and the erectile function was measured with Sexual Health Inventory for Men (SHIM).Factors associated with ED were analyzed with multivariate logistic regression. 【Results】 A total of 300 questionnaires were distributed, and 276 valid ones were collected, including 182 cases (65.9%) suffering from ED of varying degrees.Multivariate logistic regression analysis showed that age [(<30 years/>50 years, OR: 0.120, 95%CI: 0.033-0.405, P<0.001), (30-40 years/>50 years, OR: 0.223, 95%CI: 0.102-0.463, P<0.001), (>40-50 years/>50 years, OR: 0.320, 95%CI: 0.139-0.719, P<0.01)], level of International Prostate Symptom Score (IPSS) (OR: 1.95, 95%CI: 1.211-3.248, P<0.01), International Prostate Symptom Score-Quality of Life item (IPSS-QoL) (OR: 1.482, 95%CI: 1.201-1.854, P<0.01), and income [(≥10 000 Yuan/<3 000 Yuan, OR: 0.156, 95%CI: 0.053-0.429, P<0.001), (5 000-<10 000 Yuan/<3 000 Yuan, OR: 0.418, 95%CI: 0.199-0.864, P<0.05), (≥10 000 Yuan/3 000-<5 000 Yuan, OR: 0.205, 95%CI: 0.069-0.573, P<0.01)] were independent and significant factors of ED. 【Conclusion】 The prevalence of ED in renal transplantation recipients is high.Age, income, IPSS and IPSS-QoL are the influencing factors.ED after renal transplantation is not only determined by physical and functional factors, but also closely related to social and psychological factors.

Objective: To describe the prevalence of permanent tooth caries and associated factors among junior high school students in Haikou, and to provide reliable evidence for prevention and control of caries. Methods: A total of 3 573 students from 8 junior high school in Haikou City and towns were selected by the methods of clustered sampling survey. Questionnaire survey and oral health examinations were conducted to analyze the caries rate, mean decayed missing filled tooth (DMFT), filling rate, pit and fissure sealant rate. Logistic regression was used to analyze the influencing factors of caries in permanent tooth. Results: Among the surveyed junior high school students, the caries rate was 47.32%( n =1 691), the mean DMFT was 1.51. The caries rate and mean DMFT were higher in female students (49.59%) than in male students (44.95%), and higher in towns (50.77%) than in urban areas (44.04%), the difference were statistically significant ( χ 2=16.25, 7.72, P <0.05). The filling rate and pit and fissure sealant rate among junior high school students in Haikou were 17.13%, 6.27% respectively. The filling rate and pit and fissure sealant rate were higher in urban areas (18.97%, 7.17%) than towns (15.76%, 5.33%), the difference were statistically significant ( χ 2= 9.57, 5.13, P <0.05). The multivariate Logistic analysis showed that female student, town residence, daily consumption of sweets or sugary drinks (≥1 time), bedtime snack were risk factors for junior high school students suffering from permanent dental caries( OR =1.41, 1.45, 2.63, 2.09, 1.53), while using fluoride toothpaste daily, oral education in school were protective factors( OR =0.44, 0.34)( P <0.05). Conclusion The caries rate of permanent teeth among junior high school students in Haikou is at high level, but the filling rate of caries and pit and fissure sealant rate are lower. The prevention and treatment of dental caries should be carried out in high risk students, and oral health education in school is also needed to improve the oral health level of junior high school students.

BACKGROUND: Tri-ponderal mass index (TMI) has been reported to be a more accurate estimate of body fat than body mass index (BMI). This study aims to compare the effectiveness of TMI and BMI in identifying hypertension, dyslipidemia, impaired fasting glucose (IFG), abdominal obesity, and clustered cardio-metabolic risk factors (CMRFs) in 3- to 17-year-old children. METHODS: A total of 1587 children aged 3 to 17 years were included. Logistic regression was used to evaluate correlations between BMI and TMI. Area under the curves (AUCs) were used to compare discriminative capability among indicators. BMI was converted to BMI- z scores, and accuracy was compared by false-positive rate, false-negative rate, and total misclassification rate. RESULTS: Among children aged 3 to 17 years, the mean TMI was 13.57 ± 2.50 kg/m 3 for boys and 13.3 ± 2.33 kg/m 3 for girls. Odds ratios (ORs) of TMI for hypertension, dyslipidemia, abdominal obesity, and clustered CMRFs ranged from 1.13 to 3.15, higher than BMI, whose ORs ranged from 1.08 to 2.98. AUCs showed similar ability of TMI (AUC: 0.83) and BMI (AUC: 0.85) in identifying clustered CMRFs. For abdominal obesity and hypertension, the AUC of TMI was 0.92 and 0.64, respectively, which was significantly better than that of BMI, 0.85 and 0.61. AUCs of TMI for dyslipidemia and IFG were 0.58 and 0.49. When 85th and 95th of TMI were set as thresholds, total misclassification rates of TMI for clustered CMRFs ranged from 6.5% to 16.4%, which was not significantly different from that of BMI- z scores standardized according to World Health Organization criteria. CONCLUSIONS TMI was found to have equal or even better effectiveness in comparison with BMI in identifying hypertension, abdominal obesity, and clustered CMRFs TMI was more stable than BMI in 3- to 17-year-old children, while it failed to identify dyslipidemia and IFG. It is worth considering the use of TMI for screening CMRFs in children and adolescents.

Objective:To explore the characteristics of abnormal chromosome karyotype of common external genital malformations in male children.Methods:A retrospective analysis of the clinical data of 2 408 children was made in outpatient or inpatient from January 2012 to December 2017. The mean age was (38±7) months. There were 1115 cases of hypospadias, 189 cases of cryptorchidism, 304 cases of micropenis, 681 cases of concealed penis and 119 cases of disorders of sex development. All children were tested for chromosome 550 band in peripheral blood, and the results of chromosome karyotype were analyzed.Results:A total of 131 cases of abnormal chromosome karyotypes were detected, with a detection rate of 5.4%, including 46 cases of chromosome number abnormalities, 85 cases of structural abnormalities, 64 cases of sex chromosome abnormalities and 67 cases of autosomal abnormalities. The karyotype of chromosome was 46, XY, inv (9) (p12q13) in 28 cases accounting for 21.4%. It was followed by 47, XXY, with 16 cases, accounting for 12.2%. The detection rate of chromosomal abnormalities in children with disorders of sex development was 12.6%(15 cases), hypospadias was 5.5%(61 cases), cryptorchidism was 5.3%(10 cases), micropenis was 4.9%(15 cases), and concealed penis was 4.4%(30 cases).Conclusions:Chromosomal abnormalities are not uncommon in male children with external genital malformations. Chromosome structural abnormalities are more common than quantitative abnormalities, and sex chromosome abnormalities account for a comparable proportion to autosomal abnormalities.

To investigate the intestinal amino acids pathway in depression-like offspring rats induced by maternal separation. Sprague-Dawley (SD) female rats were randomly divided into a control group (=8) and a maternal separation group (=8). After normal delivery, the maternal rats were separated from offsprings for 14 consecutive days and 3 h per day in maternal separation group; while rats in the control group was received no interventions in postpartum. Depression-like behaviors of offspring rats were evaluated using the sucrose preference test, novelty suppressed feeding test, and forced swimming test. Amino acid analyzer was used to detect the changes of amino acid contents in the small intestine, and the expressions of alanine-serine-cysteine transporter 2 (ASCT2), solute carrier superfamily 6 member 19 (BAT1) and L-type amino acid transporter 1(LAT1) were detected by Western blot. The weight of the offspring rats in the maternal separation group was significantly lower than that of the control group at 21 and 28 d (=4.925 and 5.766, all <0.01). Compared with the control group, the percentage of sucrose preference of the offspring rats in the maternal separation group was significantly reduced (=2.709, <0.05), and the feeding latency was significantly prolonged (=-13.431, <0.01). The immobility time in FST of maternal separation group was significantly longer (=-3.616, <0.01).Increased concentration of aspartic acid (=-6.672, <0.01) and down-regulation of glutamine (=3.107, <0.01) and glycine (=9.781, <0.01) were observed in maternal separation group. Western blot analysis revealed that the protein expressions of ASCT2 (=6.734, <0.01) and BAT1 (=9.015, <0.01) in maternal separation group were reduced, while the expression of LAT1 was increased (=-8.942, <0.01). Maternal separation can induce the depression-like behavior in offspring rats; the amino acid contents and the amino acid transporter expression in the small intestine are reduced, which may be related to depression-like behavior induced by maternal separation.

Objective:To investigate the therapeutic effect of dorsal skin-tightening technique on the correction of mild penile curvature in children with hypospadias.Methods:The clinical characteristics of hypospadias patients (95 cases) with mild penile curvature (<30°) after degloving penis during operation in our hospital from Jan 2017 to Sep 2020 were analyzed retrospectively. Group A: A new technique, reconstructing penile pubic angle at 12 o'clock position of penile dorsal side after degloving and suturing forskin outer and inner plate with tension at 12 o'clock position, was performed in dorsal skin-tightening group (43 cases). Gtoup B: while in dorsal midline tunica albuginea plication group (52 cases), Buck fascia was incised on dorsal midline area, following by tunica albuginea plication with one or two stitches. The patients in Group A were 0.4 to 1.5 years old, and the median age was 1.1 years, urethral orifice were located on distal shaft in 36 cases, proximal in 7 cases.The patients in Group B were 0.5 to 2.6 years old, and the median age was 1.5 years, urethral orifice were located on distal shaft in 41 cases, proximal in 11 cases. The penile ventral curvature degree was recorded during regular follow-up (postoperative 6 and 12 months), as well as postoperative complications.Results:Artificial erection test showed penile curvature was corrected during surgery by measuring with protractor. There was no chordee by measuring with the side photos in all patients during an average of 1.6 years follow-ups. There were 4 case of urethral fistula in Group B and 3 cases in Group A. No cases of urethrostenosis, diverticulum or concealed penis was recorded. The difference of postoperative complications had no statistical significance.Conclusion:Hypospadias with mild penile curvature could be effectively corrected by dorsal skin-tightening technique, which showed a good result of early follow-up.
