RESUMEN
Objective:To analyze the clinical and genetic characteristics of congenital hypogonadotropic hypogonadism (CHH) in boys.Methods:Cross-sectional study.Clinical data, laboratory data and genetic results of boys who were genetically diagnosed with CHH at the Department of Endocrinology of Shenzhen Children′s Hospital from December 2019 to February 2023 were collected in this retrospective study.Their clinical manifestations, hormone levels and gene mutations were analyzed.The non-normal distribution was represented by the median.The rank sum test was used to compare the non-normal distribution data between the two groups.Results:A total of 27 boys were genetically diagnosed with CHH, with the age at first diagnosis ranging from 0.3 to 16.6 years old.All these children presented with micropenis (100%), of whom 16 were complicated with cryptorchidism (59.3%), 9 with microrchidia (33.3%), 7 with simple micropenis (25.9%), and no had simple cryptorchidism.Three children had cardiovascular dysplasia.The median of basal luteinizing hormone(LH) level was 0.09 IU/L, and 92.5%(25/27) of children had the basal LH level below 1.00 IU/L.The median of peak LH level after gonadotropin-releasing hormone(GnRH) stimulation was 1.42 IU/L, and 96.2%(26/27) of children had the peak LH level below 4.00 IU/L.The median of serum inhibin B was 41.15 μg/L, and the median of serum anti-Müllerian hormone(AMH) was 12.62 mg/L.The serum AMH level of children with cryptorchidism was significantly lower than that of children without cryptorchidism (10.02 mg/L vs.50.50 mg/L, P<0.05). A total of 12 gene mutations were detected in the 27 children, of which 1 was biallelic mutation.The most common gene mutations were in CHD7 and ANOS1 genes (7 children each, both accounting for 51.8%), followed by FGFR1 gene (3 children, 11.1%). After short-term treatment by GnRH pump or subcutaneous injection of recombinant human follicle stimulating hormone in 4 children, the levels of serum inhibin B and AMH increased significantly, and the testicular volume also increased. Conclusions:CHH is a congenital disease with different clinical manifestations at different ages.The main manifestations in childhood are micropenis and cryptorchidism, and some children have microrchidia.Its diagnosis in prepuberty is difficult, but genetic testing is of great significance for early diagnosis.
RESUMEN
OBJECTIVE@#To explore the coincidence rate of G-banding karyotype analysis and fluorescence in situ hybridization (FISH) for the diagnosis of children with sex chromosome mosaicisms.@*METHODS@#A retrospective analysis was carried out for 157 children with suspected sex chromosome abnormalities who had presented at Shenzhen Children's Hospital from April 2021 to May 2022. Interphase sex chromosome FISH and G-banding karyotyping results were collected. The coincidence rate of the two methods in children with sex chromosome mosaicisms was compared.@*RESULTS@#The detection rates of G-banding karyotype analysis and FISH were 26.1% (41/157) and 22.9% (36/157) , respectively (P > 0.05). The results of G-banding karyotype analysis showed that 141 cases (89.8%) were in the sex chromosome homogeneity group, of which only 5 cases (3.5%) were inconsistent with the results of FISH. There were 16 cases (10.2%) in the sex chromosome mosaicism group, of which 11 cases (68.8%) were inconsistent with the results of FISH. There was a statistical difference between the two groups in the coincidence rate of the results of the two methods (P < 0.05).@*CONCLUSION@#No significant difference was found between G-banding karyotype analysis and FISH in the detection rate of chromosome abnormalities. The coincidence rate in the mosaicism group was lower than that in the homogeneity group, and the difference was statistically significant. The two methods should be combined for clinical diagnosis.

To summarize the clinical manifestations of a case with 46, XY sex development disorder caused by myelin regulatory factor(MYRF) gene mutation and review the literature to deepen the specialists′ understanding of the clinical disease spectrum resulting from MYRF gene variations. The child had a female phenotype with mild masculinity, chromosome 46, XY, sex-determining region of Y gene(SRY gene) positive, laboratory tests were consistent with primary hypogonadism, ultrasound did not detect the gonads, but the residual reproductive tract was visible, and echocardiography suggested coarctation of the aorta, MYRF gene c. 2518C>T(p.R840*) heterozygous variant. The father did not carry this variant. The mother was untraceable, and genetic testing had not been completed. It was analyzed as pathogenic variation according to American College of Medical Genetics and Genomics(ACMG) guidelines. Sixteen cases of disorders of sex development caused by MYRF gene variation reported from 2018 to 2021 were reviewed, MYRF gene variants, 46, XY, and 46, XX individuals can be pathogenic, can affect the gonad and reproductive tract at the same time, and can also affect multiple systems. In this case, the patient presents with 46, XY sex development disorder due to MYRF gene mutation, accompanied by rare cardiovascular complications. When encountering 46, XY primary hypogonadism without well-developed Müllerian duct structures, this condition should be considered. Following confirmation, a comprehensive assessment of multi-organ function is necessary.

RESUMEN
OBJECTIVE: To investigate the effectiveness and safety of tripterygium glycosides (TG) tablet for the treatment of Lupus nephritis (LN). METHODS: Several databases were systematically searched including PubMed, Embase, Cochrane, Wiley, China National Knowledge Infrastructure Database, SinoMed and Wanfang Library till June 20, 2020. Revman5.3 was utilized to analyze the data according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement. RESULTS: In total, 8 randomized controlled trials involving 583 participants were identified. Meta-analyses showed that, compared with glucocorticoids (GC) alone, the combination with TG tablet provided a statistically significant improvement in total remission (TR) ( = 1.27, 95% : 1.08-1.50, = 0.004), complete remission (CR) ( = 1.61, 95% : 1.05-2.47, = 0.03) and C3 levels ( = 0.27, 95% : 0.14-0.39, < 0.000 1), C4 levels ( = 0.12, 95% : 0.07-0.17, < 0.000 01). No significant differences were seen in TR, CR, proteinuria, serum creatinine, C3 and C4 (TR: = 1.00, 95% : 0.87-1.16, = 0.95; CR: = 1.10, 95% : 0.78-1.56, = 0.58; proteinuria levels: = -0.06, 95% : -0.13 to 0.01, = 0.10; serum creatinine levels: = -0.01, 95%: -7.36 to 7.35, = 1.00; C3 levels: = 0.01, 95%: -0.06 to 0.07, = 0.84; C4 levels: = -0.01, 95%: -0.03 to 0.01, = 0.49) between azathioprine (AZA) / leflomit (LEF) + GC and TG tablet + GC. Adverse events (hepatic dysfunction, nausea, vomitting) showed no statistical differences between the TG tablet + GC group and the GC group. There were more new onset of irregular menstruation in the TG tablet + GC group than those in the AZA + GC ( = 3.57, 95% : 1.40-9.11, = 0.008) /LEF+ GC ( = 6.69, 95% : 2.42-18.46, = 0.000 2) group, but leucopenia lower than those in AZA + GC group ( = 0.38, 95% : 0.17-0.85, = 0.02) and alopecia ( = 0.14, 95% : 0.03-0.77, = 0.02) and rash ( = 0.09, 95% : 0.01-0.69, = 0.02) lower than those in LEF + GC group. CONCLUSIONS: This review indicates that TG tablet maybe effective in LN treatment. Nevertheless, adverse events cannot be ignored. Large sample, multi-center, high-quality clinical studies are needed to verify the exact effects and safety of TG tablet in treatment of LN.

RESUMEN
To analyze the perceptions of cardiovascular specialists about Behcet′s disease and its cardiovascular lesions in Beijing Anzhen Hospital, Capital Medical University. A survey using questionnaires was conducted among cardiovascular specialists in the hospital, the differences among groups were analyzed with χ2 analyses. Less than half of the cardiovascular specialists were familiar with the diagnostic criteria of Behcet′s disease (32.6%), and its skin lesions, as acne-like rash (41.3%), erythema nodosum (42.0%), acupuncture response (47.8%). The knowledge of its cardiovascular lesions was too superficial, especially in the awareness of heart conduction block. Most of the specialists preferred to use low dose of glucocorticoids before operation in their practice. To improve the knowledge and awareness of Behcet′s disease and its cardiovascular lesions is of great significance for the early diagnosis, improvement of prognosis, and reduction of postoperative complications.
RESUMEN
Objective:To summarize the clinical manifestations of four patients with 46, XY disorders of sex development(46, XY DSD)due to doublesex and mab-3 related transcription factor 1(DMRT1)gene variant/haploinsufficiency, and to improve the understanding of clinicians for this disease.Methods:The medical history, physical examination, endocrine function assessment, gonadal pathology, and genetic data of 4 patients with 46, XY DSD were retrospectively collected.Results:A heterozygous new missense mutation in DMRT1 was found in one child. The chief complain was primary amenorrhoea at the age of 15 years, with the external masculinisation score(EMS)0. The DMRT1 haploinsufficiency was found in 3 cases, 1.2 Mb, 5.1 Mb, and 6.0 Mb fragments were deleted at the 9p, and one of 3 cases had 33.3 Mb repeats in the 5p. All patients visited doctor under 1 year. Two patients were raised as females, and one was raised as male. All chief complains were external genital abnormalities, EMS of them were 1, 0, and 5 respectively. Endocrine evaluation of 2 out of 4 children showed varying degrees of primary hypogonadism, and presented with complete gonadal dysgenesis. One patient showed a well function of Leydig cells and poorly function of Sertoil cells, and presented with mixed gonadal dysgenesis. One of 3 cases was diagnosed with gonadoblastoma at the age of 18 months. Patient No.4 didn′t agree with the gonadal biopsy. The chromosome karyotypes of 4 children were 46, XY.Conclusions:The visiting ages of 46, XY DSD patients caused by DMRT1 variation were older than those of patients caused by DMRT1 haploinsufficiency. The clinical manifestations are complex, and gonadal function can vary from normal to complete gonadal dysgenesis. Such patients are at high risk of gonadoblastoma and young onset. Gonadal biopsy should be performed as early as possible.

Objective To observe the expressing changes of apolipoprotein M (ApoM),tumor necrosis factor-α(TNF-α) and monocyte chemoattractant protein-1 (MCP-1) in human retinal vascular endothelial cells (HRECs) under the high glucose culture condition and investigate the inhibitory effects of ApoM overepression on the expressions of TNF-α and MCP-1.Methods HRECs were cultured in DMEM containing 10% fetal bovine serum and 5.5 mmol/L D-glucose and assigned to 6 groups.The cells in the normal control group were cultured in above culture medium;the cells in the high glucose group were treated using the DMEM with 30 mmol/L D-glucose;ApoM was transfected into the cells using lentiviral vector in the ApoM transfected group;lentiviral vector without ApoM sequence was transfected in the empty vector group;the cells transfected by empty vector were cultured in high glucose culture medium in the empty vector+high glucose group;the cells in the ApoM transfection+high glucose group were treated by ApoM sequence transfection and high glucose incubation.The relative expression of ApoM,TNF-α and MCP-1 mRNA was detected using real-time quantitative PCR,and the relative expression of ApoM protein was evaluated using Western blot assay.Results Compared with the normal control group,the mRNA expression levels of ApoM,TNF-α and MCP-1 in the high glucose group were significantly increased (t=5.517,3.295,2.555;all P<0.05).HRECs grew well after infected with lentivirus.The relative expression level of ApoM mRNA in the ApoM transfected group was 236.400±39.270,which was significantly higher than 1.000±0.153 in the empty vector group (t=5.995,P<0.01).An enhanced protein band of ApoM was seen in the ApoM transfected group,and the protein band was absent in the empty vector group.The relative expression band in the ApoM transfected group was 1.000± 0.249 and 2.978 ± 0.285 in the cells cultured with normal culture medium or high glucose culture medium,respectively,with a significant difference between them (t =5.056,P<0.01).The relative expressions of TNF-α and MCP-1 in the mRNA levels were significantly different among the empty vector group,empty vector+high glucose group,ApoM transfected group and ApoM transfection + high glucose group (F =5.966,P =0.026;F =14.410,P =0.002).Compared with the empty vector+high glucose group,the relative expressions of TNF-α and MCP-1 mRNA were considerably reduced in the ApoM transfection+high glucose group (P=0.017,0.004).Conclusions High glucose environment up-regulates the expression of ApoM,MCP-1 and TNF-α in HRECs.Overexpression of ApoM inhibits the up-regulation of MCP-1 and TNF-α expression induced by high glucose.
RESUMEN
Objective To investigate the clinical characteristics and prognostic factors for patients with primary intestinal B-cell lymphoma. Methods The clinical data of 50 patients with primary intestinal B-cell lymphoma in Fujian Medical University Union Hospital from January 2004 to December 2013 were retrospectively analyzed. An analysis was also conducted in their clinical characteristics and related prognostic factors. Results A total of 50 patients included 35 males and 15 females with the median age of 58 years old (16-79 years old). The clinical symptoms were abdominal pain or abdominal distension [70 % (35/50)]. The common origins were small intestine and ileocecus, and the most common pathological type was diffuse large B-cell lymphoma (DLBCL) [54 % (27/50)]. The median survival time of 43 cases was 49.4 months. The 1-year, 3-year and 5-year overall survival (OS) rates were 79.1 %, 72.1 %, 58.1 %, respectively. Univariate analysis indicated that hemoglobin levels, albumin levels, lactic dehydrogenase (LDH), the maximum diameter of mass, international prognostic index (IPI) score, Lugano stage, and Eastern Cooperative Oncology Group (ECOG) score were the affecting factors of OS. Multivariate analysis showed that IPI score ≥ 2 was an independent risk factor for the prognosis of intestinal B-cell lymphoma ( OR= 6.766, 95 % CI 1.853-24.702, P= 0.004). The efficacy analysis showed that 5-year cumulative OS rate of R-CHOP like treatment group was better than that of CHOP like treatment group (91.7 % vs. 44.7 %, P =0.048). Conclusion IPI score can be used as an important indicator for clinical treatment and prognosis evaluation of primary intestinal B-cell lymphoma. Some patients with primary intestinal B-cell lymphoma can benefit from rituximab.

RESUMEN
<p><b>OBJECTIVE</b>To investigate the status of exclusive breastfeeding(EBF) and possible influencing factors during 0-7 days postpartum in China.</p><p><b>METHODS</b>During 2011 to 2013, healthy mothers and neonates who were in the period of 0- 7 days postpartum from 8 provinces across different regions of China were recruited to take the questionnaire investigations and physical examinations. Information about socio-economic, pregnant, and delivery status, infant healthy situation and feeding indicators was collected to calculate the rate of exclusive breastfeeding during 0- 7 days postpartum and analyze the influencing factors.</p><p><b>RESULTS</b>A total of 1 882 pairs of mothers and neonates were covered by this study. The rate of EBF was 13.3% (250 cases) during 0- 7 days postpartum. Bottle feeding (OR=0.08, 95% CI: 0.05- 0.12), the mothers themselves mixed fed at their 0-4 months old (OR=0.22, 95%CI: 0.08-0.58), the mothers who had used methods to stimulate milk secretion (OR=0.58, 95% CI: 0.35- 0.94) might decrease the EBF rate. Compared with the mothers who believed that their breast milk was not enough for their infants, the mothers who believed breastmilk was enough may increase the EBF rate (OR=6.04, 95%CI: 3.34-10.94). Comparing to the EBF rate of Beijing, Yunnan (OR=0.10, 95%CI: 0.04-0.24), and Gansu(OR=0.03,95%CI: 0.01-0.08) had lower EBF rate during 0-7 days postpartum. What's more, the EBF rate increased with the increasing neonates' age (OR=1.33, 95% CI: 1.16- 1.53).</p><p><b>CONCLUSION</b>The EBF rate during 0- 7 days postpartum is still low in China and had significant differences in different regions. Suboptimal feeding knowledge and practices affected the EBF rate significantly.</p>
