OBJECTIVE: To investigate the therapeutic effect of the short-penis treatment apparatus and wide-band infrared therapy apparatus on penile dysplasia (PDP) in children and establish objective parameters for assessing the severity of PDP. METHODS: This study included 252 children received in the Department of pediatric urology of the First Affiliated Hospital of Xinjiang Medical University from January to December 2023, 102 with PDP (the PDP group) and the other 150 with normal penile development (the control group), those of the former group treated with the short-penis therapeutic apparatus and wide-band infrared therapy apparatus. Before and after 30 days of treatment, we measured the flaccid penile length (FPL), stretched penile length (SPL) and penile diameters (PD) of the children, and defined the penile dysplasia index as the FPL/SPL and FPL/PD ratios. RESULTS: The penile parameters exhibited statistically significant differences between the PDP and control groups, (FPL:［1.97±0.72］cm vs ［3.25±0.51］ cm, P<0.01; SPL:［3.80±0.81］cm vs ［5.21±0.79］cm,P<0.01).The FPL remarkably increased in the PDP group after treatment(［1.97±0.72］cm vs ［2.90±1.20］ cm, P<0.01). Both FPL and SPL were notably shorter in the PDP cases than in the controls, with the cutoff values of 0.57 and 2.09, sensitivities of 80.7% and 95.3%, and specificities of 69.6% and 82.4% for FPL/SPL and FPL/PD, respectively. CONCLUSION The short-penis therapeutic apparatus and wide-band infrared therapy apparatus can promote the growth and development of the penis in children. The ratio of FPL/PD can serve as an objective indicator to effectively describe the severity of penile developmental abnormalities.

OBJECTIVE: To investigate the clinical effect of physical intervention combined with medical nutritional weight loss (PI+MNWL) in the treatment of short penis in obese children. METHODS: One hundred and twenty obese children with a short penis were included and equally divided into three groups: PI+MNWL, MNWL, and self-guided diet, who underwent PI+MNWL, MNWL intervention under the supervision of professional nutritionists in the hospital, or self-guided diet intervention at home, respectively, all for 30 days. We measured the penile parameters, including stretched penile length (SPL), flaccid penile length (FPL) and penile diameter (PD), of the children before and after treatment, and compared them among the three groups. RESULTS: After intervention, the body weight of the children was significantly decreased in all the three groups (27.1－94.1［53.59±11.88］ kg vs 23.0－85.1［49.01±11.61］ kg， P < 0.05). The weight of children in 3 groups decreased to different degrees, and the difference was statistically significant (P < 0.05). MNWL was found remarkably more effective than self-guided weight loss in reducing the body weight of the children (P < 0.05). Based on weight loss achieved through medical nutrition combined with physical intervention, the FPL in the PI+MNWL group increased from (1.93 ± 0.76) cm before treatment to (3.41 ± 1.41) cm after one course of comprehensive treatment, with a statistically significant difference (P < 0.05). Similarly, SPL increased from (3.75 ± 0.76) cm before treatment to (4.98 ± 0.64) cm, and PD increased from (1.32 ± 0.21) cm before treatment to (1.61 ± 0.66) cm, both showing statistically significant differences (P < 0.05). In the MNWL group , FPL increased from (2.01 ± 0.81) cm to (2.77 ± 0.84) cm after one course of treatment, with a statistically significant difference (P < 0.05). Additionally, SPL increased from (4.03 ± 0.84) cm before treatment to (4.40 ± 0.76) cm, also demonstrating statistical significance (P < 0.05), while PD increased from (1.37 ± 0.21) cm before treatment to (1.42 ± 0.22) cm, with statistical significance (P < 0.05). FPL and SPL increased significantly in the PI+MNWL group compared to the MNWL group (P < 0.05, P < 0.01). However, there was no significant difference in PD between the two groups following the intervention (P > 0.05). CONCLUSION MNWL is more effective than self-guided diet in controlling the body weight of children, while the combination approach of PI+MNWL is even superior to the management of short penis in obese children, with the advantages of improving the appearance and increasing the exposed length of the penis.

Previous studies have identified two group-level processes, neural representations of interracial between-group difference and intraracial within-group similarity, that contribute to the racial categorization of faces. What remains unclear is how the brain tracks race-related information that varies across different faces as an individual-level neural process involved in race perception. In three studies, we recorded functional MRI signals when Chinese adults performed different tasks on morphed faces in which proportions of pixels contributing to perceived racial identity (Asian vs White) and expression (pain vs neutral) varied independently. We found that, during a pain expression judgment task, tracking other-race and same-race-related information in perceived faces recruited the ventral occipitotemporal cortices and medial prefrontal/anterior temporal cortices, respectively. However, neural tracking of race-related information tended to be weakened during explicit race judgments on perceived faces. During a donation task, the medial prefrontal activity also tracked race-related information that distinguished between two perceived faces for altruistic decision-making and encoded the Euclidean distance between the two faces that predicted decision-making speeds. Our findings revealed task-dependent neural mechanisms underlying the tracking of race-related information during face perception and altruistic decision-making.

Objective To explore the correlation between hospitalization for severe asthma and climate change among adult residents in Dalian. Methods Clinical data of asthma inpatients in Dalian First Affiliated Hospital from January to December 2022 were collected, and assigned into severe asthma group and non-severe asthma group according to the diagnostic criteria of severe asthma. Spirometer was used for the measurement of (forced expiratory volume in the first second , FEV1) and (forced vital capacity , FVC), and the serum white blood cell count and C-reactive protein level were measured by biochemical analyzer. Meantime, meteorological parameters including monthly average temperature, relative humidity, wind speed and duration of sunshine hours were also collected. Then Spearman correlation analysis was conducted to discuss the correlation between the number of hospitalizations for severe asthma and meteorological parameters. Of the 260 asthma patients, 153 had severe asthma and 107 had non-severe asthma. There were 85 male and 68 female patients with severe asthma. The onset age distribution of severe asthma was concentrated at 60-79 years old, with 94 cases, followed by 50-59 years old (n=26). The peak time of onset in each year was from March to May, with 14, 19 and 16 cases, respectively. The secondary peak was from November to January, with 15, 18 and 13 cases, and there were fewer hospital admissions from June to October. FEV1 and FEV1/FVC values were smaller in severe asthma group than in non-severe asthma group, while the white blood cell count and C-reactive protein levels were higher than those in non severe asthma group (P<0.05). The average monthly temperature in Dalian began to rise in January, reached a peak in August, and then gradually dropped, with the lowest temperature in December. The monthly average humidity reached the peak from July to September. The monthly mean wind speed reached its peak from November to December. The monthly average sunshine reached its peak from June to September. Spearman correlation analysis denoted that the number of hospitalization for severe asthma was not correlated with average sunshine hours and wind speed (P>0.05), but was negatively correlated with average temperature and humidity (P<0.05). Conclusion The number of hospital admissions for severe asthma in Dalian varies with the seasons, therefore, early and active interventions are of great value in preventing severe asthma in months with high variations in temperature and humidity.

italic>Polygonum capitatum is a characteristic Miao medicine in Guizhou, commonly used in clinical practice to treat gastrointestinal and urinary tract infections. Research has found that it has good antibacterial and anti-inflammatory effects, and its main active ingredient is flavonoids. Lavonoid O-methyltransferase (FOMT) is a key enzyme for oxymethylation modification of flavonoid compounds. In order to understand the function and properties of FOMT protein in Polygonum capitatum, the transcriptome was sequenced by Illumina HiSeq 4000 high throughput sequencing technology. Then, the obtained transcripts were annotated and analyzed, and the whole genome of the FOMT gene family in Polygon capitalis was mined and identified. A total of 99 298 Unigenes were obtained, of which 71 514 were successfully annotated by the public database. In the genome of Polygonum capitatum, a total of 50 FOMT genes were identified. The phylogenetic tree showed that FOMT genes were divided into two subfamilies: caffeoyl CoA O-methyltransferase (CCoAOMT) and caffeic acid O-methyltransferase (COMT). Gene sequence analysis showed that the number of FOMT encoded amino acids ranged from 99 to 1 053 aa, the molecular weight ranged from 11 224.91 to 86 687.42 Da, and the isoelectric point ranged from 4.79 to 9.45. The 50 FOMT family members were hydrophobic proteins. Subcellular localization results showed that 54% of FOMT subfamily CCoAOMT and COMT members were located in cytoplasm and 28% were located in chloroplasts. The FOMT gene was tissue specific and highly expressed in the flowers of Polygonum capitatum, followed by the stems, and the least expressed in the roots. In this study, the FOMT gene family of Polygonum capitatum was identified and analyzed to provide theoretical basis for further study of FOMT function and biosynthesis of methylated flavonoids.

Objective: To explore the diagnosis, surgical management and outcome of jugular foramen chondrosarcoma (CSA). Methods: Fifteen patients with jugular foramen CSA hospitalized in the Department of Otorhinolaryngology Head and Neck Surgery of Chinese PLA General Hospital from December 2002 to February 2020 were retrospectively collected,of whom 2 were male and 13 were female, aging from 22 to 61 years old. The clinical symptoms and signs, imaging features, differential diagnosis, surgical approaches, function of facial nerve and cranial nerves IX to XII, and surgical outcomes were analyzed. Results: Patients with jugular foramen CSA mainly presented with facial paralysis, hearing loss, hoarseness, cough, tinnitus and local mass. Computed tomography (CT) and magnetic resonance (MR) could provide important information for diagnosis. CT showed irregular destruction on bone margin of the jugular foramen. MR demonstrated iso or hypointense on T1WI, hyperintense on T2WI and heterogeneous contrast-enhancement. Surgical approaches were chosen upon the sizes and scopes of the tumors. Inferior temporal fossa A approach was adopted in 12 cases, inferior temporal fossa B approach in 2 cases and mastoid combined parotid approach in 1 case. Five patients with facial nerve involved received great auricular nerve graft. The House Brackmann (H-B) grading scale was used to evaluate the facial nerve function. Preoperative facial nerve function ranked grade Ⅴ in 4 cases and grade Ⅵ in 1 case. Postoperative facial nerve function improved to grade Ⅲ in 2 cases and grade Ⅵ in 3 cases. Five patients presented with cranial nerves Ⅸ and Ⅹ palsies. Hoarseness and cough of 2 cases improved after operation, while the other 3 cases did not. All the patients were diagnosed CSA by histopathology and immunohistochemistry, with immunohistochemical staining showing vimentin and S-100 positive, but cytokeratin negative in tumor cells. All patients survived during 28 to 234 months' follow-up. Two patients suffered from tumor recurrence 7 years after surgery and received revision surgery. No complications such as cerebrospinal fluid leakage and intracranial infection occurred after operation. Conclusions: Jugular foramen CSA lacks characteristic symptoms or signs. Imaging is helpful to differential diagnosis. Surgery is the primary treatment of jugular foramen CSA. Patients with facial paralysis should receive surgery in time as to restore the facial nerve. Long-term follow-up is necessary after surgery in case of recurrence.

Objective To compare the efficacy, safety, and survivability of TCbHP versus AC-THP in the neoadjuvant therapy of HER2-positive breast cancer in real-world. Methods Clinical data of patients with HER2 positive breast cancer, who have received TCbHP or AC-THP as neoadjuvant therapy and completed surgery in 11 third-class hospitals in various cities of Hebei Province, were retrospectively collected.The total pathological complete remission (tpCR) rate, the incidence of grade 3 or higher adverse reactions and the completion rate of the given approaches were compared. Results A total of 110 cases were collected, including 78 cases in the TCbHP group and 32 cases in the AC-THP group.The tpCR rate of the TCbHP group was higher than that of the AC-THP group, but the difference was not statistically significant (64.10% vs. 56.25%, P=0.441).No significant difference was found in the breast pathologic complete response (bpCR) and axillary pathologic complete response (apCR) rates between the TCbHP group and the AC-THP group (70.51% vs. 56.25%, P=0.150;78.21% vs. 84.38%, P=0.462).Exploratory analysis revealed that the tpCR rate of the TCbHP group was significantly higher than that of the AC-THP group in patients with HR-positive breast cancer (51.11% vs. 22.22%, P=0.036).As for the patients with HR-negative breast cancer, the tpCR rate of the AC-THP group tended to be higher than that of the TCbHP group (100% vs. 81.82%, P=0.088).The incidence of grade 3 or higher adverse reactions in the TCbHP group was slightly higher than that in the AC-THP group (12.82% vs. 9.38%, P=0.753).No deaths occurred in the whole group.Moreover, no significant difference was observed in the completion rate of the given approaches between the TCbHP group and the AC-THP group (92.31% vs. 90.63%, P=0.718). Conclusion In real-world clinical practice, the neoadjuvant therapy of TCbHP and AC-THP are effective, safe, and well tolerated among patients with HER2-positive breast cancer.The tpCR rate between the two approaches was not significantly different.The AC-THP regimen could also be considered as one of the optimal regimens for HER2-positive breast cancer in neoadjuvant therapy.

Objective: To inhibit the stemness maintenance potential of endometrial cancer and increase the sensitivity of endometrial cancer side population cells to chemotherapy drugs by inducing extensive deSUMOylation modification of proteins. Methods: Flow cytometry was used to sort and culture CD133(+) CD44(+) KLE endometrial cancer cell clone spheres. Protein expression level of small ubiquitin-related modifier 1 (SUMO1) and two stemness maintenance genes of tumor side population cells, octamer binding transcription factor-4 (Oct4) and sex determining region Y-box2 (Sox2), were detected by western blotting method. Lentivirus-mediated Sentrin/SUMO-specific proteases 1 (SENP1) gene was stably transfected into KLE side population cells. Western blotting was used to detect the protein expressions of SENP1, SUMO1, Oct4 and Sox2. The clone formation rate was compared between KLE side population cells with or without SENP1 overexpression. Flow cytometry was applied to detect cell cycle changes. 3-(4, 5-Dimethylthiazole-2)-2, 5-diphenyl-tetrazolium bromide (MTT) experiment and flow cytometry apoptosis method were used to detect the chemosensitivity of the side population of endometrial cancer cells to cisplatin. Tumor-bearing mouse models of endometrial cancer were established to detect the effect of SENP1 overexpression on the chemotherapy sensitivity of cisplatin. Results: Compared with CD133(-)CD44(-) KLE cells, CD133(+) CD44(+) KLE side population cells could form clonal spheres and express higher levels of SUMO1, Oct4 and Sox2 proteins (P<0.05). Compared with KLE side population cells that were not transfected with SENP1 gene, the expression level of SENP1 protein in KLE side population cells overexpressing SUMO1、Oct4 and Sox2 were lower. The clonal sphere formation rate was reduced from (25.67±5.44)% to (7.46±1.42)%, and cell cycle shifted from G(0)/G(1) phase to G(2) phase. IC(50) of cisplatin decreased from (55.46±6.14) μg/ml to (11.55±3.12) μg/ml, and cell apoptosis rate increased from (9.76±2.09)% to (16.79±3.44)%. Overexpression of SENP1 could reduce the tumorigenesis rate of KLE side population cells in vivo and increase their chemotherapy sensitivity to cisplatin (P<0.05). Conclusion: Overexpression of SENP1 can induce protein deSUMOylation modification, inhibit the stemness maintenance potential of endometrial cancer side population cells, and enhance their chemotherapy sensitivity, which provides a new reference for gene therapy of endometrial cancer.

Nuclear magnetic resonance spectroscopy is one of the main analytical techniques for detecting metabolomics, which has the advantages of simple operation, rapid detection and non-invasive feature. By monitoring the changes of metabolites in the body, it is helpful to deeply understand the mechanism of disease and play a role in the diagnosis and treatment of diseases, but its clinical application has not yet been popularized. In recent years, the application of metabolomics in tumors has increasingly become a research hotspot. Therefore, in order to provide a reference for the research and clinical application of tumor metabolomics, the nuclear magnetic resonance spectroscopy and tumor metabolomics were introduced in this paper, and the application progress of metabolomics analysis based on this technique in early tumor screening, clinical diagnosis and prognosis evaluation were reviewed in this paper.
