Objective To evaluate the relationship between endometriosis fertility index (EFI) and pregnancies after laparoscopic surgery in endometriosis-associated infertility.Methods From Jan.2005 to Jan.2010,medical documents of 350 infertile patients due to endometriosis undergoing laparoscopic surgery were studied retrospectively.Pregnancy outcomes were followed up by telephone.EFI was calculated by history factors,least function score and some aspects of the revised American Fertility Society (r-AFS) endometriosis stage.The cumulative pregnancy rate was calculated and compared by Kaplan-Meier survival analysis.Results Within 3 years after surgery,the cumulative pregnancy rates among patients with EFI score 8,9,10 were 62.5％,69.8％ and 81.1％,respectively.There was no significant difference in pregnancy rates among those three groups of patients ( P =0.24 ).The cumulative pregnancy rates among patients with EFI score 5,6,7 were 49.8％,43.9％ and 41.6％,respectively,which did not reach statistical difference ( P =0.83 ).The cumulative pregnancy rates of EFI score 8 - 10 was significantly higher than that of EFI score 5 -7 (71.8％ vs.44.4％,P =0.000).The patients with EFI score 0 -4 was quite small with only 33 cases,among which 15 cases were pregnant.Conclusions There is relationship between EFI and pregnancy in patients with endometriosis-associated infertility.EFI is meaningful to guide post surgical treatment.

Objective To investigate the genomic amplification of the human telomerase RNA component (hTERC) gene in cervical cytology and evaluate its role in screening of cervical lesions. Methods A total of 301 cases were recruited, with liquid-based cytology diaghoses as normal (n=203), atypical squamous cells (ASC, n=66), low-grade squamous intraepithelial lesions ( LSIL,n=18), and high-grade squamous intraepithelial lesions ( HSIL, n=14). Following cytological examination, the slides were analyzed using a two-color fluorescence in aitu hybridization ( FISH ) probe targeted to chromosome 3q26 containing hTERC. The hTERC findings were compared to the cytologic and histologie results, as well as high-risk human papilloma viruses (HPV) results. Results Genomie amplification of hTERC was found in 3.0% (6/203)of normal specimens, 21.2% (14/66) of ASC, 44.4% (8/18) of LSIL and 92.9% (13/14) of HSIL, with a significant difference in each pair wise (all P<0.05). Significantly more cells with 3q26 gain were found in cervical intraepithelial lesion (CIN) Ⅱ than in CIN Ⅰ(75.0% vs. 20.0% ), as well as in CIN Ⅲ (86.7% vs. 20.0% ) and squamous cervical cancer (SCC) than in CIN Ⅰ (100.0% vs. 20.0%) ( all P<0.01). The sensitivity of hTERC amplification was significantly higher than cytological screening (82.6% vs. 17.4%, P<0.01), and its specificity was higher than high-risk HPV test (67.8%-73.5% vs. 25.6%-27.7%, P<0.01) in the diagnosis of HSIL (CIN Ⅱ - Ⅲ). The abnormal hTERC signal type mostly was 2:3 in CIN Ⅰ (84.9% ) ; whereas in CIN Ⅱ-Ⅲ, 2: 3, 2:4 and 4:4 accounted for 44.6%, 24.8% and 17.8%, respectively. Conclusion Testing the gain of chromosome 3q26 in cytological specimens using specific probe for hTERC is powerful in screening of HSIL, and the amplification patterns of 2:4 and 4:4 may serve as potential prognosis markers.

Objective: To analyze the association between each regional fat mass and total body bone mineral density (BMD) in children and adolescents aged 7-17 years in Beijing, so as to provide theoretical basis and practical guidance for implementing interventions. Methods: From September to December 2020, a stratified cluster random sampling method was used to select 1 423 children and adolescents aged 7-17 years in Tongzhou District, Beijing. Dual energy X-ray absorptiometry (DXA) was employed to measure regional body composition and total body BMD. Multiple linear regression was used to analyze the association between regional fat mass and total body BMD. Results: The median (interquartile range) fat mass values for total body, upper limbs, abdomen, hips, and thighs were 13.51(8.84, 19.21), 1.59(1.08, 2.23), 0.73(0.39, 1.29), 2.32(1.46, 3.26), 5.29(3.59, 7.21)kg, respectively. After adjusting for covariates, the results of multiple linear regression analysis showed that total body fat mass (β=0.010), abdominal fat mass (β=-0.100), and hip fat mass (β=0.104) were significant associations with total body BMD (all P<0.01). Sexstratified analysis revealed that in boys, total body fat mass (β=0.008) and hip fat mass (β=0.058) were positively associated with BMD, while thigh fat mass (β=-0.038) showed a negative association with total body BMD (all P<0.05). In girls, total body fat mass (β=0.013), hip fat mass (β=0.163), and thigh fat mass (β=0.023) were positively associated with total body BMD, whereas abdominal fat mass (β=-0.196) showed a negative association with total body BMD (all P<0.05). Among children and adolescents with body fat percentage below the standard range, within the standard range and above the standard range, total body fat masses were positively associated with total body BMD (β=0.021, 0.016, 0.015); among children and adolescents with body fat percentage within the standard range while upper limb (β=-0.042), abdominal (β=-0.067), and thigh fat mass (β=-0.018) showed negative associations with total body BMD, and hip fat mass demonstrated a positive association with total body BMD (β=0.082) (all P<0.05). Conclusion Regional fat distribution is associated with total body BMD in children and adolescents, with the nature of these associations varying by sex and body fat percentage.

Objective To investigate the significance of genomic amplification of the telomerase RNA component (TERC) gene to serve as a genetic biomarker in the screening of cervicallesions.Methods A total of 715 cases were recruited,with liquid-based cytology diagnosis as normal (n=347),atypical squamous cells of undetermined significance (ASCUS,n=180),atypical squamous cells cannot exclude a high-grade lesion (ASC-H,n=13),low-grade squamous intraepithelial lesions (LSIL,n=115),high-grade squamous intraepithelial lesions(HSIL,n=59)and atypical glandular cells(AGC,n=1).The remaining cervical cells in the cytological preserving fluid were analyzed using a two-color fluorescence in situ hybridization (FISH) probe targeted to chromosome 3q26 containing TERC gene.The TERC gene findings were compared to the cytological and histological detected results,as well as high-risk human papillomavirus (HPV) detected results.Results Genomic amplification of TERC gene was found in 5.8% of normal specimens,22.2% of ASCUS.30.8% of ASC-H,27.8% of LSIL,86.4% of HSIL and 1/1 of AGC.The positive rate was significantly lower in normal,ASCUS,ASC-H and ISIL.compared with HSIL(all P<0.01).Significantly more cells with genomic amplification of TERC gene were found in cervical intraepithelial lesion(CIN) Ⅱ-Ⅲ than CIN Ⅰ (77.8% vs.9.3%),as well as invasive cervical cancer (96.7% vs.9.3%).both P < 0.01.The rate of TERC gene amplification was higher in HPV positive patients (33.5%) than in HPV negative patients(5.2%,P<0.01).The sensitivity of TERC gene amplification was significantly higher than that of cytological screening (81.88% vs.36.96%,P<0.01) in the differentiation of CIN Ⅱ or higher and CIN Ⅰ or lower diseases,its specificity Was hisher than high-risk HPV test (93.32% vs.33.93%,P<0.01) and positive prediction value (81.29%) was similar with cytological method (86.44%,P>0.05);but its negative prediction value (93.56%) was lower than HPV test (97.06%,P<0.05).Conclusions The positive rates of TERC gene amplification increased as cervical diseases worsened.TERC gene amplification is related to HPV infection.The gain of chromosome 3q26 in cytological specimens is an effective molecular genetic biomarker in screening of CIN Ⅱ or higher and invasive cervical cancer.

Objective:To investigate the relationship between double-triggering and abnormal movement of air in the lungs (pendelluft phenomenon) under pressure support ventilation (PSV).Methods:A prospective observational study was conducted, postoperative patients admitted to department of critical care medicine of Beijing Tiantan Hospital, Capital Medical University from April 1, 2019 to August 31, 2020 and received invasive mechanical ventilation with PSV mode were enrolled. Electrical impedance tomography (EIT) monitoring was performed. Airway pressure-time, flow-time, global and regional impedance-time curves were synchronously collected and analyzed offline. The volume of abnormal movement of air in the lungs at the beginning of inspiration was measured and defined as pendelluft volume. Double-triggered breaths were identified by trained researchers. Pendelluft volume during double-triggering was measured including the first triggered breath, the double-triggered breath, and the breath immediately following the double-triggered breath. Pendelluft volume was also measured for normal breath during the study. According to the frequency of double-triggering, patients were divided into severe (≥1 time/min) and non-severe double-triggering group. Pendelluft volume, parameters of respiratory mechanics, and clinical outcomes between the two groups were compared.Results:In 40 enrolled patients, a total of 9 711 breaths [(243±63) breaths/patient] were collected and analyzed, among which 222 breaths (2.3%) were identified as double-triggering. The Kappa of interobserver reliability to detect double-triggering was 0.964 [95% confidence interval (95% CI) was 0.946-0.982]. In 222 double-triggered breaths, pendelluft volume could not be measured in 7 breaths (3.2%), but the pendelluft phenomenon did exist as shown by opposite regional impedance change at the beginning of double-triggered inspiration. Finally, pendelluft volume was measured in 215 double-triggered breaths. Meanwhile, 400 normal breaths (10 normal breaths randomly selected for each patient) were identified as control. Compared with normal breath, pendelluft volume significantly increased in the first breath, the double-triggered breath, and the following normal breath [mL: 3.0 (1.4, 6.4), 8.3 (3.6, 13.2), 4.3 (1.9, 9.1) vs. 1.4 (0.7, 2.8), all P < 0.05]. Patients in severe double-triggering, pendelluft volume of normal breath and double-triggered breath were significantly higher than those in non-severe double-triggering group [mL: 1.8 (0.9, 3.2) vs. 1.1 (0.5, 2.1), P < 0.001; 8.5 (3.9, 13.4) vs. 2.0 (0.6, 9.1), P = 0.008]. Patients in severe double-triggering group had significantly higher respiratory rate than that in the non-severe double-triggering group (breaths/min: 20.9±3.5 vs. 15.2±3.7, P < 0.001). There were no significant differences in other respiratory mechanics parameters and main clinical outcomes between the two groups. Conclusions:During PSV, the abnormal movement of air in the lungs (pendelluft phenomenon) was more likely to occur in double-triggering especially in double-triggered breath. The more frequent the double-triggering occurred, the more serious the pendelluft phenomenon was. A higher pendelluft volume of normal breath and a higher respiratory rate were related to severity of double-triggering.
