OBJECTIVE: To explore the role of prostate health index (PHI) and its derivatives for early screening in patients with PI-RADS score 3 and prostate-specific antigen (PSA) levels of 4－20 μg/L. METHODS: Clinical data of 203 patients with a score of 3 on the PI-RADS v2.1 scoring system who underwent ultrasound-guided transperineal prostate aspiration biopsy from April 2021 to April 2024 from Provincial Hospital of Shandong First Medical University, Qilu Hospital of Shandong University and Weifang People's Hospital were collected. Patients who met the inclusion criteria were divided into prostate cancer (PCa) group (62 cases) and benign prostatic hyperplasia (BPH) group (141 cases). Serum total prostate-specific antigen (tPSA), serum free prostate-specific antigen (fPSA), and PSA isoform 2 (p2PSA) were routinely detected after admission. And prostate-specific antigen density (PSAD), prostate health index (PHI) and prostate health index density (PHID) were calculated with the basic personal information being collected. The efficacy of each parameter in early screening of patients with PI-RADS score of 3 and PSA level of 4－20 μg/L was assessed using ROC curve approach. RESULTS: There was no statistical difference in tPSA, fPSA and fPSA/tPSA between the two groups (P>0.05). There was a statistical difference in p2PSA, PSAD, PHI, PHID and age between the two groups (P<0.05). PHI (AUC=0.783 7, 95% CI: 0.711 3－0.856 1) and PHID (AUC=0.782 3, 95% CI: 0.708 3－0.856 4) showed a good predictive ability in the early screening of prostate cancer. In the clinically significant prostate cancer (csPCa) group, the ROC curve areas of PHI and PHID were 0.823 0 and 0.788 5, respectively, which showed better predictive efficacy of prediction of csPCa. The ROC curves of the combined diagnostic indexes were plotted on the basis of the independent ROC curves, and the area under the curve of PHI combined with age, p2PSA and PHID (AUC=0.843 6) was the largest and had the best predictive ability among all the combined diagnostic indexes. CONCLUSION In patients with PI-RADS score 3 and PSA level between 4 and 20 μg/L, PHI and its derivatives (PHI and PHID) provide a new way for early screening of prostate cancer compared with the traditional index tPSA, which has a high value of application in reducing the over-penetration.

Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson tumor, is a rare vascular benign tumor of blood vessels. It may occur in any part of the body, especially the deep dermis and subcutaneous tissue of the head, neck, fingers and trunk. The imaging and histopathology of IPEH are similar to hemangiosarcoma, especially in the case of active vascular endothelial hyperplasia. IPEH is a reactive proliferative lesion of vascular intima. The etiology is still unclear. After some studies showed that IPEH was a benign lesion, few reports on the etiology of it were reported. IPEH is usually limited to the thrombotic vessels or lumens of vascular malformations, usually accompanied by a clear history of trauma. IPEH usually does not cause any symptoms. It looks like a slow-growing lump. Some cases have been reported with pain and swelling. Although IPEH is relatively rare, its accurate diagnosis is crucial because it may be similar to malignant angiogenic lesions in clinical practice. There were few reports of cases related to intravascular papillary endothelial hyperplasia located in the sternocleidomastoid muscle after reviewing the domestic and foreign literature in recent 10 years. This case reports that a young male, who was admitted to the hospital one month after finding a subcutaneous tumor in the left neck. After admittance, relevant preoperative examinations were completed. After multi-disciplinary discussion and elimination of surgical contraindications, a specific surgical plan was formulated. The tumor was removed under local anesthesia on the second day after admission. During the operation, it was found that the tumor was located between the sternocleidomastoid muscle bundles, and it was sent for pathologic examination. Paraffin section pathology was reported after operation. Histological examination showed that the morphology was consistent with vascular endothelial papillary hyperplasia. There were no related surgical complications and recurrence in the 3-month follow-up. The purpose of this paper is to provide clinicians with a certain understanding of this rare disease through the report of this case of IPEH, and to identify it in later clinical work, and at the same time, to avoid confusion with malignant diseases, such as hemangiosarcoma, leading to unnecessary treatment and increase the cost of treatment.

Objective: To compare the effects and safety of dydrogesterone (DG) and medroxyprogesterone acetate (MPA) on the treatment in patients with endometrial hyperplasia without atypia (EH). Methods: This was a single-center, open-label, prospective non-inferior randomized controlled phase Ⅲ trial. From February 2019 to November 2021, patients with EH admitted to the Obstetrics and Gynecology Hospital of Fudan University were recruited. Enrolled patients were stratified according to the pathological types of simple hyperplasia (SH) or complex hyperplasia (CH), and were randomised to receive MPA or DG. Untill May 14, 2022, the median follow-up time after complete response (CR) was 9.3 months (1.1-17.2 months). The primary endpoint was the 6-month CR rate (6m-CR rate). The secondary endpoints included the 3-month CR rate (3m-CR rate), adverse events rate, recurrence rate, and pregnancy rate in one year after CR. Results: (1) A total of 292 patients with EH were enrolled in the study with the median age of 39 years (31-45 years). A total of 135 SH patients were randomly assigned to MPA group (n=67) and DG group (n=68), and 157 CH patients were randomly assigned to MPA group (n=79) and DG group (n=78). (2) Among 292 patients, 205 patients enrolled into the primary endpoint analysis, including 92 SH patients and 113 CH patients, with 100 patients in MPA group and 105 in DG group, respectively. The 6m-CR rate of MPA group and DG group were 90.0% (90/100) and 88.6% (93/105) respectively, and there were no statistical significance (χ²=0.11, P=0.741), with the rate difference (RD) was -1.4% (95%CI:-9.9%-7.0%). Stratified by the pathology types, the 6m-CR rate of SH patients was 93.5% (86/92), and MPA group and DG group were respectively 91.1% (41/45) and 95.7% (45/47); and the 6m-CR rate of CH patients was 85.8% (97/113), and MPA group and DG group were 89.1% (49/55) and 82.8% (48/58) respectively. The 6m-CR rates of the two treatments had no statistical significance either (all P>0.05). A total of 194 EH patients enrolled into the secondary endpoint analysis, including 88 SH patients and 106 CH patients, and 96 patients in MPA group and 98 in DG group, respectively. The 3m-CR rate of SH patients were 87.5% (77/88), while the 3m-CR rates of MPA group and DG group were 90.7% (39/43) and 84.4% (38/45), respectively; the 3m-CR rate of CH patients was 66.0% (70/106), and MPA group and DG group had the same 3m-CR rate of 66.0% (35/53). No statistical significance was found between the two treatments both in SH and CH patients (all P>0.05). (3) The incidence of adverse events between MPA group and DG group had no statistical significance (P>0.05). (4) A total of 93 SH patients achieved CR, and the cumulative recurrence rate in one year after CR were 5.9% and 0 in MPA group and DG group, respectively. While 112 CH patients achieved CR, and the cumulative recurrence rate in one year after CR were 8.8% and 6.5% in MPA group and DG group, respectively. There were no statistical significance between two treatment groups (all P>0.05). Among the 93 SH patients, 10 patients had family planning but no pregnancy happened during the follow-up period. Among the 112 CH patients, 21 were actively preparing for pregnancy, and the pregnancy rate and live-birth rate in one year after CR in MPA group were 7/9 and 2/7, while in DG group were respectively 4/12 and 2/4, and there were no statistical significance in pregnancy rate and live-birth rate between the two treatment groups (all P>0.05). Conclusions: Compared with MPA, DG is of good efficacy and safety in treating EH. DG is a favorable alternative treatment for EH patients.

Objective: To investigate the clinicopathological features and possible mechanisms of burned-out testicular germ cell tumors. Methods: The clinical and imaging data, histology and immunophenotypic characteristics of three cases of burned-out testicular germ cell tumors diagnosed at the Ruijin Hospital, Medical College of the Shanghai Jiaotong University, from 2016 to 2020 were retrospectively analyzed. The relevant literature was reviewed. Results: The mean age of the three patients was 32 years. Case 1 had an elevated preoperative alpha-fetoprotein level (810.18 μg/L) and underwent "radical pancreaticoduodenectomy and retroperitoneal lesion resection" for a retroperitoneal mass. Postoperative pathology showed embryonal carcinoma, which needed to exclude gonadal metastasis. Color Doppler ultrasound showed a solid mass of the right testis, with hypoechoic lesion and scattered calcification in some areas. Case 2 was a "right supraclavicular lymph node biopsy specimen." Chest X-ray showed multiple metastases in both lungs. The biopsy showed metastatic embryonic carcinoma and bilateral testicular color Doppler ultrasound revealed abnormal calcifications in the right testicle. Case 3 showed a cystic mass of the right testis with calcification and solid areas. All 3 patients underwent radical right orchiectomy. Grossly, borders of the testicular scar areas were well defined. Cross sectioning of the tumors showed a gray-brown cut surface and single focus or multiple foci of the tumor. The tumor maximum diameter was 0.6-1.5 cm. Microscopically, lymphocytes, plasma cells infiltration, tubular hyalinization, clustered vascular hyperplasia and hemosiderin laden macrophages were found in the scar. Atrophic and sclerotic seminiferous tubules, proliferation of clustered Leydig cells and small or coarse granular calcifications in seminiferous tubules were present around the scar. Seminoma and germ cell neoplasia in situ were seen in case 1, germ cell neoplasia in situ was seen in case 2 and germ cells with atypical hyperplasia were seen in case 3. Immunohistochemistry showed that embryonic carcinoma expressed SALL4, CKpan(AE1/AE3) and CD30, seminoma and germ cell tumor in situ expressed OCT3/4, SALL4 and CD117, and spermatogenic cells with atypical hyperplasia expressed CD99 and SALL4. The Ki-67 positive index was about 20%, while OCT3/4 and CD117 were both negative. Conclusions: Burned-out testicular germ cell tumors are rare. The possibility of gonad testicular metastasis should be considered first for extragonadal germ cell tumor. If fibrous scar is found in testis, it must be determined whether it is a burned-out testicular germ cell tumor. The burned-out mechanisms may be related to the microenvironment of tumor immune-mediated and local ischemic injury.

Dentofacial deformities secondary to condylar hyperplasiais a kind of disease presenting facial asymmetry, malocclusion, temporomandibular joint dysfunction, and other symptoms caused by non-neoplastic hyperplasia of the condyle. The etiology is still unknown, and currently, pre- and post-operative orthodontics accompanied by orthognathic surgery, temporomandibular joint surgery and jawbone contouring surgery are the main treatment methods. A personalized treatment plan was developed, considering the active degree of condyle hyperplasia, the severity of the jaw deformity, and the patient's will, to correct deformity, obtain ideal occlusal relationship, and regain good temporomandibular joint function. Combined with the author's clinical experience, the etiology, clinical and imageological features, treatment aims, and surgical methods of condylar hyperplasia and secondary dentofacial deformities were discussed in this paper.

Stevens-Johnson syndrome (SJS), also known as the multifactorial erythematous drug eruption, is a class of adverse reactions of the skin and mucous membranes primarily caused by drug allergy often involving the oral cavity, eyes, and external genital mucosa, generally accompanied by fever, and can be life-threatening in severe cases. In February 2022, the Department of Stomatology, the First Affiliated Hospital of Zhengzhou University admitted a patient with huge inflammatory hyperplasia of bilateral lingual margins secondary to SJS. Upon admission, no other obvious symptoms were observed except for tongue hyperplasia. The patient suffered from a severe adverse drug reaction caused by acetaminophen 2 months ago and was complicated by liver dysfunction and pulmonary infection. After 1 month of treatment and rehabilitation, he developed a secondary tongue mass and was subsequently admitted to Dept. of Oral and Maxillofacial Surgery Ward 2, the First Affiliated Hospital of Zhengzhou University. After completing the examination, the tongue mass was surgically removed. After a follow-up of 11 months, the patient's condition was satisfactory and no temporary discomfort was observed. The case of tongue mass secondary to SJS is extremely rare. If a stomatologist encounters a similar case, we should carefully inquire about the drug allergy history and recent medication history, and be alert to whether or not they had adverse drug reactions recently.

OBJECTIVES: To investigate the therapeutic effect of recombinant human growth hormone (rhGH) on children with growth hormone deficiency (GHD) and different pituitary developmental conditions. METHODS: A prospective study was performed on 90 children with GHD who were admitted to Xuchang Maternity and Child Health Hospital from June 2020 to December 2021. According to pituitary height on the median sagittal plane, they were divided into three groups: pituitary dysplasia group (n=45), normal pituitary group (n=31), and enlarged pituitary growth group (n=14). The changes in body height, growth velocity, height standard deviation score and serum levels of insulin-like growth factor binding protein-3 (IGFBP-3) and insulin-like growth factor-1 (IGF-1) were examined after treatment in the above three groups, and the differences of the above indices before and after treatment were compared among the three groups. RESULTS: After treatment, all three groups had significant increases in body height, growth velocity, height standard deviation score, and the serum levels of IGFBP-3 and IGF-1 (P<0.05). Compared with the normal pituitary group, the pituitary dysplasia group and the enlarged pituitary growth group had significantly higher values in terms of the differences in body height, growth velocity, height standard deviation score, IGF-1, and IGFBP-3 before and after treatment (P<0.05). There was no significant difference in the incidence rate of adverse reactions among the three groups (P>0.05). CONCLUSIONS In GHD children with different pituitary developmental conditions, rhGH can promote bone growth and increase body height, especially in children with pituitary dysplasia and pituitary hyperplasia, with good safety.

OBJECTIVES: To investigate the clinical phenotypes, genetic characteristics, and pathological features of children with disorders of sex development (DSD). METHODS: A retrospective analysis was conducted on epidemiological, clinical phenotype, chromosomal karyotype, gonadal pathology, and genotype data of 165 hospitalized children with DSD at Children's Hospital of Hebei Province and Tangshan Maternal and Child Health Hospital from August 2008 to December 2022. RESULTS: Among the 165 children with DSD, common presenting symptoms were short stature (62/165, 37.6%), clitoromegaly (33/165, 20.0%), cryptorchidism (28/165, 17.0%), hypospadias (24/165, 14.5%), and skin pigmentation abnormalities/exteriorized pigmented labia majora (19/165, 11.5%). Chromosomal karyotype analysis was performed on 127 cases, revealing 36 cases (28.3%) of 46,XX DSD, 34 cases (26.8%) of 46,XY DSD, and 57 cases (44.9%) of sex chromosome abnormalities. Among the sex chromosome abnormal karyotypes, the 45,X karyotype (11/57, 19%) and 45,X/other karyotype mosaicism (36/57, 63%) were more common. Sixteen children underwent histopathological biopsy of gonadal tissues, resulting in retrieval of 25 gonadal tissues. The gonadal tissue biopsies revealed 3 cases of testes, 3 cases of dysplastic testes, 6 cases of ovaries, 11 cases of ovotestes, and 1 case each of streak gonad and agenesis of gonads. Genetic testing identified pathogenic/likely pathogenic variants in 23 cases (23/36, 64%), including 12 cases of 21-hydroxylase deficiency congenital adrenal hyperplasia caused by CYP21A2 pathogenic variants. CONCLUSIONS Short stature, clitoromegaly, cryptorchidism, hypospadias, and skin pigmentation abnormalities are common phenotypes in children with DSD. 45,X/other karyotype mosaicism and CYP21A2 compound heterozygous variants are major etiological factors in children with DSD. The most commonly observed gonadal histopathology in children with DSD includes ovotestes, ovaries, and testes/dysgenetic testes.

OBJECTIVE: To understand the biological characteristics of polycythemia vera (PV) patients with myeloid fibroplasia, and further analyze the risk factors affecting myeloid fibroplasia in PV patients, so as to provide ideas for predicting the occurrence of myeloid fibroplasia in PV patients. METHODS: Forty patients with PV in the Department of Hematology, Xiyuan Hospital of China Academy of Chinese Medical Sciences were collected and divided into two groups, with (hyperplasia group) and without (Non-proliferative group) hyperplasia of bone marrow fibers. The differences of basic clinical characteristics, blood routine, biochemistry, bone marrow cells, coagulation function and other indicators between the two groups were compared, and the independent risk factors affecting the proliferation of bone marrow fibrous tissue in PV patients were further analyzed by multivariate regression. RESULTS: Compared with Non-proliferative group, the JAK2 mutation rate (95% vs 70%，P=0.037), eosinophilic cell count (0.19 vs 0.11, P=0.047) and eosinophilic percentage (1.84 vs 1.27, P=0.001) in PV patients with hyperplasia were significantly increased, triglycerides (1.55 vs 1.91, P=0.038) and low-density lipoprotein (1.50 vs 3.08, P=0.000) were significantly reduced, bone marrow hematopoietic volume (0.85 vs 0.6, P=0.001), granulocyte/erythrocyte ratio (3.40 vs 1.89, P=0.033), lymphocyte/erythrocyte ratio (0.60 vs 0.42, P=0.033), and granulocyte+lymphocyte/erythrocyte ratio (3.72 vs 2.37, P=0.026) were significantly increased, thrombin time (18.84 vs 18.12, P=0.043) was significantly prolonged. Multivariate regression analysis results showed that peripheral blood eosinophil ≥2% and low-density lipoprotein ≤2 mmol/L were independent risk factors for bone marrow fibrous tissue hyperplasia in PV patients (P<0.05). CONCLUSION Increased proportion of peripheral blood eosinophils and decreased low density lipoprotein are risk factors for bone marrow fibrous tissue hyperplasia in PV patients.
