Objective To investigate gene expression of epidermal growth factor (EGF), its receptor (EGFR) and two protooncogenes (c-fos and c-myc), in fetal skin at different development stages and children skin and to delineate their potential biological significance. Methods Fetal skin biopsies of human embryo were obtained from spontaneous abortions at different gestational ages from 13 to 32 weeks and children skin specimens were collected from patients undergoing plastic surgery. After morphological characteristics of skin at different development stages were detected with histological methods, gene expressions of EGF, EGFR, c-fos and c-myc in skin at different development stages were examined with reverse transcription-polymerase chain reaction analysis (RT-PCR). Results Gene expression of EGF, EGFR, c-fos or c-myc could all be detected in fetal and childern skins. In fetal skin, the gene expression of these 4 genes was weak. Gene expression of these genes in skin was progressively enhanced with increasing gestational age. In children skin, the mRNA contents of these 4 genes were significantly increased in comparison with those in fetal skin (P

Objective To explore the change in gene expression of extracellular signal regulated protein kinase1 (erk1),erk2,p38MAPK and 3 c-Jun N- terminal kinases (jnk1,jnk2,jnk3) in fetal skin at different developmental stages and children skin. Methods After morphological characteristics of fetal skin at different developmental stages were examined histologically,gene expressions of erk1,erk2,p38MAPK,jnk1,jnk2 and jnk3 were determined with reverse transcription-polymerase chain reaction analysis (RT-PCR). Results Compared with early gestational fetal skin,the levels of gene expression of erk1 and erk2 showed no substantial change in late gestational fetal skin,while the contents of transcripts of p38MAPK and jnk1 were significantly decreased,the expressions of mRNA of jnk2 and jnk3 were obviously elevated. In children skin,gene expressions of erk2,p38MAPK and jnk1 were even more remarkably lowered. In contrary,gene expressions of jnk2 and jnk3 were marked enhanced. Conclusion The relative elevation of gene transcription of erk2 and p38MAPK and the inhibition of gene expression of jnk2 and jnk3 in fetal skin of earlier developmental stage might be related to fetal scarless healing.

Objective To study the differentially expressed genes between keloids and normal control skin using cDNA microarray. Methods The PCR products of 8400 human genes were spotted on a chemical-material-coated-glass plate in array. Total RNAs were isolated from the freshly excised human keloids and normal control skin,and then were purified to mRNAs,which were reversely transcribed to cDNAs with the incorporations of fluorescent dUTP,for preparing the hybridization probes. The mixed probes were hybridized to the cDNA microarray. According to the results of cDNA microarray,three genes (NGF,TGF-?_ 1 and c-myc) were chosen to study their differential expression in keloids and normal control skin by RT-PCR. Results Among the 8400 target genes,there were 402 genes with different expression (4.75%),and they were mainly associated with extracellular matrix genes,cellular signal molecule genes and cellular skeleton molecule genes. Analysis of collagen related molecule and growth factor gene expression confirmed that our molecular data obtained by cDNA microarray were consistent with published biochemical and clinical observations of keloids. RT-PCR showed that the levels of gene expression of NGF,TGF-?_ 1 and c-myc were all higher in keloids than those in normal control skin. Conclusion Many genes were found to be involved in the formation of keloids. Further analysis of the obtained genes might contribute to reveal the molecular mechanism of keloids formation,in which NGF,TGF-?_ 1 and c-myc might play important roles.

AIM: To investigate gene expression of bax, bcl-2 and p53 in fetal skin at different gestational ages and children skin in order to explore their potentially biological significance. METHODS: Apoptosis in skin specimens was determined by terminal deoxynucleotidy transferase mediated dUTP-biotin nick-end labeling technique (TUNEL). Gene expressions of bax, bcl-2 and p53 in skin at different developmental stages was examined with reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: Along with fetal growth and development, the incidence rate of apoptosis was increased progressively in skin. In skin from early gestational fetus, bcl-2 was strongly expressed. This gene expression was progressively decreased with increment in gestational age. In children skin, the mRNA content of this gene was significantly reduced compared with fetal skin (P

Objective To explore the efficiency of prophylactic intravesical chemotherapy after nephroureterectomy for primary upper tract urothelial carcinoma.Methods Forty-seven patients with primary upper tract urothelial carcinoma who underwent nephroureterectomy were retrospectively analyzed.There were 25 male and 22 female patients with mean age of 68 years.Patients were divided into intravesical chemotherapy group (n =32) and non-intravesical chemotherapy group (n =15).In the intravesical chemotherapy group, there were 14 male and 18 female patients with mean age of 70.3 years;20 cases located at left side while 12 at the right side.In non-intravesical chemotherapy group, There were 11 male and 4 female patients with mean age of 65.0 years;10 cases located at left side while 5 at the right side.The age, gender, side of the two groups were not statistical different.The two groups were followed up, and the tumor stage, grade, recurrence rate, cancer-free survival time were compared.Results The pathology results of all cases were urothelial carcinoma.In the intravesical chemotherapy group, 23 cases were high grade tumors with 9 low grade tumors.There were 15 cases of Ta-T1 stage, 8 cases of T2 stage and 9 cases of T3 stage;the tumor of 19 cases located at pelvis, 12 located at ureter, 1 located at pelvis and ureter;the mean size of the tumors was (2.75 ± 1.49) cm;8 cases were multiple while 24 were single.In the non-intravesical chemotherapy group, 12 cases were high grade tumors with 3 low grade tumors, there were 6 cases of Ta-T1 stage, 4 cases of T2 stage and 5 cases of T3 stage;the tumor of 11 cases located at pelvis, 3 located at ureter, 1 located at pelvis and ureter;the mean size of the tumors was (3.11 ± 1.48) cm;6 cases were multiple while 9 were single.The items mentioned above did not reach statistical difference between the two groups(P ＞0.05).6 patients relapsed in intravesical chemotherapy group while 7 in non-intravesical chemotherapy group.The recurrence rate of bladder cancer of intravesical chemotherapy group was lower than that of non-intravesical chemotherapy group (18.75％ vs.46.67％, χ2 =3.978, P =0.046).Compared with non-intravesical chemotherapy group, intravesical chemotherapy group had longer cancer-free survival, but it did not reach statistical difference (36.5months vs.29.6months, t =1.079, P =0.286).The age and tumor grade were risk factors of bladder cancer recurrence, meanwhile the gender, tumor side, tumor stage, voided urine cytology, tumor size, and location were not.Conclusion Prophylactic intravesical chemotherapy after nephroureterectomy for primary upper tract urothelial carcinoma could reduce the recurrence rate of bladder cancer.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

【Objective】 To compare the perioperative blood loss between interlaminar and transforaminal approaches by percutaneous endoscopic discectomy in order to provide more reference for guiding the proper choice of surgical methods clinically. 【Methods】 We retrospectively analyzed the clinical data of 160 patients who underwent percutaneous endoscopic lumbar discectomy from June 2019 to November 2020， with 80 patients in interlaminar approach group and 80 in transforaminal approach group. The blood loss was calculated according to Gross formula. 【Results】 The perioperative total blood loss （mL）， hidden blood loss （mL） and hemoglobin loss （g/L） were significantly lower in interlaminar approach group than in transforaminal approach group （119.73±179.26 vs. 158.6±190.65， 109.73±179.53 vs. 148.78±190.19， 3.76±8.12 vs. 4.31±7.62） （P<0.05）. However， there was no significant difference in visible blood loss between the two groups. 【Conclusion】 The perioperative hidden blood loss accounts for a large proportion in percutaneous endoscopic lumbar discectomy. In addition， the interlaminar approach causes less blood loss than the transforaminal approach.

This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder (ASD) in Chinese children. We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling. The Modified Chinese Autism Spectrum Rating Scale was used for the screening process. Of the target population of 142,086 children, 88.5% (n = 125,806) participated in the study. A total of 363 children were confirmed as having ASD. The observed ASD prevalence rate was 0.29% (95% CI: 0.26%-0.32%) for the overall population. After adjustment for response rates, the estimated number of ASD cases was 867 in the target population sample, thereby achieving an estimated prevalence of 0.70% (95% CI: 0.64%-0.74%). The prevalence was significantly higher in boys than in girls (0.95%; 95% CI: 0.87%-1.02% versus 0.30%; 95% CI: 0.26%-0.34%; P < 0.001). Of the 363 confirmed ASD cases, 43.3% were newly diagnosed, and most of those (90.4%) were attending regular schools, and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity. Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children.
