RESUMO

Objective: To analyze the composition of diagnosis in young inpatients with angle-closure glaucoma and to compare the clinical characteristics between primary angle-closure glaucoma (PACG) and secondary angle-closure glaucoma (SACG). Methods: This was a retrospective case series study. Angle-closure glaucoma patients aged 40 years or younger and hospitalized in Zhongshan Ophthalmic Center from January 2012 to December 2019 were included. The clinical diagnosis, gender, onset age, and results of general ophthalmic examination, A-scan ultrasonography measurements, ultrasound biomicroscopy, optical coherence tomography and visual field were recorded. The proportions and composition of PACG and SACG, as well as the misdiagnosis ratio, were analyzed. The onset age, visual acuity, visual field, and ocular parameters were compared between patients with PACG and SACG. Non-normally distributed data were represented by M (Q1, Q3). The difference between groups were compared by Mann-Whitney U test, Chi square test, and independent sample t test. Results: A total of 243 patients (243 eyes) were included in this study. The mean onset age was (28±9) years, and the male-to-female ratio was 1∶1.79. There were 93 patients (38.3%) in PACG group and 150 (61.7%) in SACG group. The age of PACG [34(28, 38)] was older than that of SACG [28(19, 34)], and the proportion of males in the SACG group (44.0%, 66/150) was significantly higher than that in the PACG group (22.6%, 21/93) (Z=-5.34, χ2=11.46; both P<0.01). Nanophthalmos (22.7%, 34 cases), autosomal recessive bestrophinopathy (ARB) (19.3%, 29 cases), uveitis (18.7%, 28 cases) and retinitis pigmentosa (14.0%, 21 cases) were the most common causes of SACG. The best corrected visual acuity (logarithm of the minimum angle of resolution) was 0.10 (0.00, 0.48) and 0.40 (0.06, 1.00), mean deviation of visual field was -8.07 (-27.49, -2.09) and -15.04 (-28.75, -5.97) dB, and subfoveal choroidal thickness was (452.3±130.7) and (396.3±120.9) µm in the PACG and SACG groups, respectively. The differences were statistically significant (Z=-4.86, -2.14; t=2.37; all P<0.05). There was no statistical difference in intraocular pressure, cup-to-disc ratio, extent of peripheral anterior synechia, central anterior chamber depth, lens thickness, mean retinal nerve fiber layer thickness between these two groups (all P>0.05). The misdiagnosis ratio was 10.7% (26/243) in all patients, while the misdiagnosis ratio of the SACG group (16.7%, 25/150) was higher than that of the PACG group (1.1%, 1/93) (χ²=14.61, P<0.001). Conclusions: PACG, nanophthalmos and ARB are the most common etiologies in young inpatients with angle-closure glaucoma. Compared to PACG, patients with SACG are younger, with worse visual acuity and more severe visual field defects, and easier to be misdiagnosed.

RESUMO

BACKGROUND: Disruption of alveolar epithelial cell (AEC) differentiation is implicated in distal lung diseases such as chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, and lung adenocarcinoma that impact morbidity and mortality worldwide. Elucidating underlying disease pathogenesis requires a mechanistic molecular understanding of AEC differentiation. Previous studies have focused on changes of individual transcription factors, and to date no study has comprehensively characterized the dynamic, global epigenomic alterations that facilitate this critical differentiation process in humans. RESULTS: We comprehensively profiled the epigenomic states of human AECs during type 2 to type 1-like cell differentiation, including the methylome and chromatin functional domains, and integrated this with transcriptome-wide RNA expression data. Enhancer regions were drastically altered during AEC differentiation. Transcription factor binding analysis within enhancer regions revealed diverse interactive networks with enrichment for many transcription factors, including NKX2-1 and FOXA family members, as well as transcription factors with less well characterized roles in AEC differentiation, such as members of the MEF2, TEAD, and AP1 families. Additionally, associations among transcription factors changed during differentiation, implicating a complex network of heterotrimeric complex switching in driving differentiation. Integration of AEC enhancer states with the catalog of enhancer elements in the Roadmap Epigenomics Mapping Consortium and Encyclopedia of DNA Elements (ENCODE) revealed that AECs have similar epigenomic structures to other profiled epithelial cell types, including human mammary epithelial cells (HMECs), with NKX2-1 serving as a distinguishing feature of distal lung differentiation. CONCLUSIONS: Enhancer regions are hotspots of epigenomic alteration that regulate AEC differentiation. Furthermore, the differentiation process is regulated by dynamic networks of transcription factors acting in concert, rather than individually. These findings provide a roadmap for understanding the relationship between disruption of the epigenetic state during AEC differentiation and development of lung diseases that may be therapeutically amenable.

RESUMO

Objective: To analyze the temporal bone CT and inner ear magnetic resonance imaging characteristics of cochlear implant patients with no cochlear nerve display in the inner auditory canal under MRI. To retrospectively analyze the long-term hearing and speech rehabilitation effects of such patients after cochlear implant. And to analyze the correlation between the results of imaging examinations and the postoperative effects of cochlear implant patients with this type of cochlear nerve deficiency. Methods: A total of 88 children with cochlear nerve deficiency, who underwent cochlear implantation in Shandong Provincial ENT Hospital from May 2014 to October 2018, were enrolled. Patients with cochlear malformations were excluded,only the patients with cochlear nerve deficiency whose cochlear structure was normal and no cochlear nerve displayed in inner auditory canal under MRI were enrolled. There were 64 patients, including 4 bilaterally implanted, 68 ears in total, with an average age of (2.8±1.7) years (range 1-6 years) at the time of implantation. The implanted product was Cochlear, including 24RECA and 512 models. All patients underwent inner ear magnetic resonance imaging and temporal bone CT scan before operation. Auditory speech function assessments were performed at 12 months, 24 months, and 36 months after surgery, including categories of auditory performance (CAP), speech intelligibility rating (SIR) and hearing aid threshold test. The imaging evaluation content included the width of the cochlear nerve canal of temporal bone CT, the width of the internal auditory canal, the width of the auditory nerve at the cerebellopontine angle of the inner ear MRI, and the ratio of the facial nerve to the width of the auditory nerve at the cerebellopontine angle. The correlations between the results of postoperative hearing aid hearing threshold, CAP, SIR and imaging results were analyzed. Results: Among the 64 cases of cochlear nerve not shown under MRI, 56 ears with CT data showed that the width of the cochlear nerve canal in temporal bone CT was (0.72±0.30) mm (mean±standard deviation, the same below), and the width of the internal auditory canal was (4.07±1.10) mm; 66 ears with MRI data showed that the diameter of the auditory nerve at the cerebellopontine angle of the inner ear MRI was (1.58±0.27) mm, the diameter of the facial nerve was (1.57±0.27) mm, and the ratio of the diameter of the facial nerve to the auditory nerve was (1.02±0.23). The average hearing thresholds at 12, 24, and 36 months after surgery were (46.8±2.5) dB HL, (40.7±0.8) dB HL, and (36.8±1.5) dB HL, respectively. The preoperative and postoperative CAP scores at 12, 24 and 36 months were (1.0±1.0), (3.8±1.4), (4.5±1.4) and (5.1±0.7) points, respectively. The preoperative and postoperative SIR scores at 12, 24, and 36 months were (1.1±0.3), (1.9±0.9), (2.5±0.9), and (2.9±0.6) points, respectively. The hearing threshold at 24 months after surgery was negatively correlated with the width of the internal auditory canal of temporal bone CT (r=-0.349, P=0.037), and the hearing threshold at 36 months after surgery was positively correlated with the ratio of the diameter of the facial nerve to the auditory nerve at the cerebellopontine angle of the inner ear MRI (r=0.740, P=0.001). Conclusions: Children with cochlear implants whose cochlear nerves are not shown on MRI can benefit from cochlear implantation, and their speech and auditory functions can improve significantly after surgery. The width of the internal auditory canal in the temporal bone CT and the ratio of the diameter of the facial nerve to the auditory nerve at the cerebellopontine angle of the inner ear MRI may be related to the long-term hearing threshold after surgery.

RESUMO

Objective: To investigate the status of height and weight of 3-18-year-old children and adolescents in urban China, and to provide a basis for establishing puberty phase specific curves for age-specific height and age-specific weight. Methods: A cross-sectional survey of 218 185 children and adolescents aged 3-18 years in urban China was conducted by using the method of stratified random cluster sampling from January 2017 to December 2019. The sampling areas included 12 provinces municipalities in China and autonomous regions in total. Data were collected on weight, height, waist circumference, hip circumference and secondary sexual characteristics. The generalized additive model for location, scale, and shape (GAMLSS) was employed to establish percentile reference values and growth curves of height and weight for boys and girls aged 3-18 years. Wilcoxon rank sum test was applied to compare the P50 value of height and weight between children of each Tanner stage and children of the same age ignoring the different puberty phase. Results: The 3rd, 50th, and 97th percentile curves for height and weight for age were developed for boys and girls aged 3-18 years. The 3rd, 50th, and 97th percentile curves for age-specific height and age-specific weight for each puberty phase were developed for boys and girls. Compared with all children ignoring the different puberty phase, boys aged 9 and over and girls aged 7 and over who are at Tanner stage 1 showed shorter height and lighter weight than those of the same age group (all P<0.01), the difference ranges of height at P50 are -4.0 to -0.6 cm for boys, and -4.4 to 0.5 cm for girls; the difference ranges of weight are -4.8 to 0.4 kg for boys, and -4.0 to -0.3 kg for girls; children at Tanner stage 2 & 3 initially were taller and heavier than those of the same age group; and later grew shorter and lighter than those of the same age group, the two sets of curves cross over; boys aged 16 and under and girl aged under 14 who are at Tanner stage 4 were taller and heavier than those of the same age group (all P<0.01), the difference ranges of height at P50 are 0.2 to 10.0 cm for boys, and 0.2 to 9.4 cm for girls; the difference ranges of weight at P50 are 0.7 to 10.9 kg for boys, and 1.0 to 11.2 kg for girls, and the differences showed narrowing trend with age. Conclusion: The puberty phase specific growth curves of age-specific height and age-specific weight for boys and girls aged 3-18 years are established, it is useful for clinical work to evaluate physical development of children at different puberty phases.

RESUMO

Objective: To assess the longitudinal changes in oral health-related quality of life (OHRQoL) and the denture satisfaction of immediate rehabilitation by implant-supported full-arch prostheses in patients of the edentulous and potential edentulous jaws. Methods: Patients in the Department of Implantology, Peking University School and Hospital of Stomatology from April 2008 to November 2020 were enrolled in the study. The treatment group (TG) consisted of 73 patients who had been treated with immediate rehabilitation by using implant-supported full-arch prostheses while the control group (CG) consisted of 31 patients who would be treated with immediate rehabilitation of implant-supported full-arch prostheses. The mean age of the patients in the treatment group was (57.5±11.1) years (ranged 31-79) and the average follow-up duration was 5.5±2.9 years (ranged 1-12). The OHRQL ratings were collected using oral health impact profile-20 (OHIP-20) and the visual analogue scales (VAS) was used to assess the denture satisfaction including stability, aesthetics, mastication, ease of cleaning, speaking and general satisfaction. Independent t-test, Mann-Whitney U-test and locally weighted scatterplot smoothing were applied for data analysis. Results: The cumulative survival rate (CSR) of the implants was 97.6% (450/461). The CSR of the prostheses was 93.3% (98/105). The average peri-implant marginal bone loss (MBL) was (0.8±0.4) mm and (1.2±0.6) mm after 1 and 5 years, respectively. The mean OHIP-20 total scores of TG and CG were 5(7) and 32.9±12.6, respectively, which had statistical difference between the two groups (P<0.001). The general satisfaction in the TG was 95.0(10.0), while the higher scores were for chewing [100.0(7.5)] stability [100.0(10.0)] and esthetics [100.0(10.0)] and the lower scores were for ease of cleaning [85.0(25.0)] and speaking ability [100.0(12.5)]. With prolonged follow-up, the total OHIP-20 score decreased significantly at first and then remained stable with minor fluctuations. Conclusions: Based on the present study, immediate rehabilitation with implant-supported full-arch prostheses was a feasible treatment program that had a long-term positive impact on OHRQoL, provided strong psychological and sociological support to the patients and restored the chewing and speech functions effectively.

RESUMO

Objective: To explore whether the cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS+HIPEC) can improve the survival rate of colorectal cancer patients with peritoneal metastasis. Methods: The relevant studies were systematically retrieved from PubMed, Embase, Cochrane Library, CNKI, Wanfang, VIP database, and the study of French Elias' team on peritoneal metastasis was retrieved manually. Inclusion criteria: (1) The patients were colorectal cancer peritoneal metastasis. (2) There were CRS+HIPEC treatments (treatment group) and other treatments (control group). (3) Survival analysis data of treatment group and control group were available. (4) Types of studies were randomized controlled trials, cohort studies, or case-control studies. (5) The literature was in Chinese or English. Exclusion criteria: (1) studies without full-text; (2) studies without complete data. The literature screening and data extraction were carried out by two people independently, and the third person decided on the literature with differences. The extracted data included authors, year of publication, number of patients, time of enrollment, time of follow-up, studies design, treatment regimen, hazard ratio (HR) and 95% CI of treatment group and control groups. If the HR and 95% CI of the treatment group and control group were not provided in the literature, Engauge Digitizer 11.1 software was used to extract the time of follow-up and the survival rate at the corresponding time point from the survival curves of both groups, and the HR and 95% CI of both groups were calculated by combining the number of both groups. The quality of study was evaluated by Newcastle-Ottawa scale (NOS) or Cochrane collaboration's tool for assessing risk bias. STATA 15.1 software was used for statistical analysis. HR and 95% CI of both groups were pooled and analyzed. Inter-trial heterogeneity was assessed by Q test and I(2) statistics. When there was no significant heterogeneity (Q test: P≥0.10), fixed-effect model was used for pooled analysis. When significant heterogeneity existed (Q test: P<0.10), random effect model was used for pooled analysis, and subgroup analysis was used to find out the source of heterogeneity. Sensitivity analysis was used to evaluate the stability of the pooled results. Publication bias was assessed by Egger's test and Begg's test (P<0.05 indicated publication bias) and it is reflected by the visual symmetry of Begg's funnel plot on the natural logarithm of HR. Results: A total of 10 studies were enrolled in the meta-analysis, including 1 randomized controlled trial and 9 cohort studies. The risk of bias in 1 randomized controlled trial was uncertain, and 9 cohort studies were all higher than 7 points, indicating high quality literatures. There were 781 patients in treatment group receiving CRS+HIPEC and 2452 patients in control group receiving other treatment, including tumor cytoreductive surgery (CRS), palliative chemotherapy (PC) and intraperitoneal chemotherapy (IPC). The results of pooled analysis by random effect model showed that the OS rate in treatment group was significantly higher than that in control group (HR=0.43, 95% CI: 0.34-0.54), but the heterogeneity of the study was high (P=0.024, I(2)=52.9%). The subgroup analysis of different control treatments showed that the OS rate in treatment group was significantly higher than that in CRS control group (HR=0.63, 95% CI: 0.44-0.90), in PC control group (HR=0.37, 95% CI: 0.32-0.43), in CRS+ IPC control group (HR=0.60, 95% CI: 0.37-0.96), and the heterogeneity of each subgroup was low (CRS control group: P=0.255, I(2)=22.9%; PC control group: P=0.222, I(2)=29.9%; CRS+IPC control group: P=0.947, I(2)=0). Due to the low heterogeneity of subgroups, fixed-effect models were used to pool and analysis. The results of sensitivity analysis revealed that there was little difference between the pooled analysis results after each study was deleted, suggesting that the pooled analysis results were more reliable. Publication bias detection of each study showed Begg's test (P=0.088) >0.05 and Egger's test (P=0.138)>0.05. According to the Begg's funnel plot, the scatter point distribution was basically symmetric, indicating that there was no publication bias in the included study. Conclusion: CRS+HIPEC can improve the OS of patients with colorectal cancer peritoneal metastasis.

RESUMO

Objective: To explore the relationship between the daily incidence of human respiratory syncytial virus (HRSV) and meteorological parameters in the main urban area of Chongqing. Methods: This study took 3 107 children hospitalized with acute lower respiratory tract infections from June 2009 to June 2019 in department of Respiratory medicine, Children's Hospital of Chongqing Medical University (CHCMU). Nasopharyngeal aspirate (NPA) was collected on the day of admission to detect HRSV and common respiratory virus; combined with the meteorological data of the main urban area of ​​Chongqing during the same period, the correlation and distribution lag nonlinear model analysis of the daily incidence of HRSV and meteorological parameters were carried out. Results: Among 3 107 children, HRSV positive accounted for 34.53% (1 073 cases), the age was 6 (3, 13) months, and males accounted for 64.31% (690 cases). The daily incidence of HRSV was negatively correlated with minimum temperature (r=-0.220, P<0.001), maximum temperature (r=-0.221, P<0.001), average temperature (r=-0.221, P<0.001) and precipitation (r=-0.052, P<0.001), and positively correlated with sunshine time (r=0.011, P<0.001) and average relative humidity (r=0.095, P<0.001). Compared with the reference temperature (20 ℃), when the lowest temperature of 6-10 ℃ lags for 4-8 d, the RR value of HRSV was 1.11-1.14, and when the lowest temperature of 5-19 ℃ lags for 5 d and 2-19 ℃ lags for 10 d, the RR values were 1.02-1.14 and 1.00-1.03. When the cumulative lag is 5, 10, 15 and 21 d, compared with the reference temperature (20 ℃), the RR (95%CI) values at the lowest temperature of 10.4 ℃ were 1.93 (1.08-3.46), 3.49 (1.64-7.45), 5.00 (2.01-12.46) and 6.69 (2.18-20.48); the RR (95%CI) values of the lowest temperature of 22.1 ℃ were 0.87 (0.77-0.98), 0.77 (0.66-0.90), 0.74 (0.62-0.89) and 0.68 (0.55-0.85). In the cumulative effect, compared with the reference temperature (20 ℃), the gender stratification showed that the maximum RR (95%CI) values of the lowest temperature for boys and girls under different lag days were 7.24 (1.84-28.51) and 2.19 (1.07-4.46), the age stratification showed that the maximum RR (95%CI) values of the lowest temperature for children<6 months old and children ≥6 months old under different lag days were 4.72 (1.05-21.23) and 11.98 (1.70-84.35). Conclusions: In the main urban area of Chongqing, the daily incidence of HRSV in children is correlated with climatic parameters. Among them, the lowest temperature has a delayed and cumulative effect on HRSV infection. 6-10 ℃ has a greater impact on the incidence of HRSV when the lag is 4-8 days. The effect has a more obvious impact on the incidence of HRSV in boys and children ≥ 6 months.

RESUMO

Objective: To evaluate the efficacy and safety profile of ixazomib/lenalidomide/dexamethasone (IRd) in Chinese patients with relapsed/refractory multiple myeloma (MM) . Methods: This study comprising 14 medical centers in China included patients with relapsed/refractory MM who received at least. Ixazomib at an initial oral dose of 4 mg was administered. Seven patients had dose adjustment to 3 mg at the time of first dose. The lenalidomide doses were adjusted according to creatinine clearance rate. The efficacy and safety were evaluated every cycle. Results: In the study cohort of 74 patients, the median age was 65 years and 11 (14.9% ) patients received over three lines of therapy. Overall response rate (ORR) was 54.1% (40/74) , and 7 (9.5% ) , 14 (18.9% ) , and 19 (25.7% ) patients achieved stringent complete response or complete response, very good partial response, and partial response, respectively. The median progression-free survival and overall survival were 9.9 and 20 months, respectively. The median time to response was 1 month. The efficacy and survival outcome were similar to those reported in the Tourmaline-MM1 China Continuous Study. The ORR of patients refractory to bortezomib, lenalidomide, and bortezomib plus lenalidomide were 52.0% (13/25) , 57.1% (4/7) , and 33.3% (6/18) , respectively. The rate of grade 3-4 adverse events was 36.5% (27/74) . Common hematological toxicities were anemia, thrombocytopenia, lymphopenia, and neutropenia. Common non-hematological toxicities were fatigue, gastrointestinal symptoms, and infections. Two cases of grade 3 peripheral neuropathy were reported. The patients eligible for the Tourmaline-MM1 China Continuous Study had a higher ORR than the ineligible patients [77.8% (14/18) vs 46.4% (26/56) , P=0.020]. There was no difference in the rate of grade 3-4 adverse events [33.3% (6/18) vs 37.5% (21/56) , P=0.749]. Conclusion: The IRd regimen had good efficacy and acceptable toxicity in Chinese patients with relapsed/refractory MM.

RESUMO

BACKGROUND: Dupilumab is an antibody against interleukin-4 receptor α, used in the treatment of atopic dermatitis (AD). OBJECTIVES: To evaluate the efficacy and safety of dupilumab in adult Chinese patients with moderate-to-severe AD. METHODS: In this randomized, double-blind, placebo-controlled, parallel-group, phase III study, conducted between December 2018 and February 2020, patients with AD received dupilumab (300 mg) or placebo once every 2 weeks for 16 weeks, and were followed up for 12 weeks. The primary efficacy endpoint was the proportion of patients with both an Investigator's Global Assessment score of 0-1 and a reduction from baseline of ≥ 2 points at week 16. RESULTS: Overall, 165 patients (mean age 30·6 years; 71·5% male patients) were randomized; 82 patients were randomized to dupilumab and 83 patients were randomized to placebo. At week 16, 26·8% of patients in the dupilumab group and 4·8% of patients in the placebo group achieved the primary endpoint [difference 22·0%, 95% confidence interval (CI) 11·37-32·65; P < 0·001]. Compared with placebo, higher proportions of patients in the dupilumab group achieved ≥ 75% reduction in the Eczema Area and Severity Index score (57·3% vs. 14·5%; difference 42·9%, 95% CI 29·75-55·97; P < 0·001) and had ≥ 3-point (52·4% vs. 9·6%; difference 42·8%, 95% CI 30·26-55·34; P < 0·001) and ≥ 4-point (39·0% vs. 4·8%; difference 34·2%, 95% CI 22·69-45·72; P < 0·001) reductions in weekly average daily peak daily pruritus numerical rating scale scores. The incidence of treatment-emergent adverse events during the treatment period was similar in the two groups. The incidence of conjunctivitis, allergic conjunctivitis and injection site reaction was higher in the dupilumab group than in the placebo group. CONCLUSIONS: In adult Chinese patients, dupilumab was effective in improving the signs and symptoms of AD and demonstrated a favourable safety profile.

RESUMO

Objective: To present the surgical technique of endoscope assisted arthroplasty for total hip replacement via minimum invasive direct anterior approach and analyze its early clinical outcome. Methods: From November 2019 to May 2020, endoscopic total hip arthroplasty via direct anterior approach was performed on 30 patients (32 hips), including 12 males (13 hips) and 18 females (19hips), in the Department of Orthopedics of Fujian Provincial Hospital. The average age of patients was (63±14) years (ranged 32-87 years). The average body mass index (BMI) of the patients was (26.9±4.5) kg/m2. There were 12 cases whose BMI was higher than 28.0 kg/m2 and the maximum BMI was 35.2 kg/m2. The surgery was performed on supine position using a 5-6 cm proximal transverse incision and a distal selective percutaneous puncture incision to perform the acetabulum preparation and the prosthesis implantation with the novel designed split tool under the monitoring of endoscope; the lift-top tractor system was used to raise the femur in the transverse incision for femoral side preparation and prosthesis implantation. Relevant data such as the perioperative status, operation time, postoperative pain score assessed with visual analogue score (VAS), prosthesis position, joint function, lateral femoral cutaneous nerve function and patient satisfaction were recorded to analyze the short-term efficacy. Results: The average length of incision of the 30 cases(32 hips)was (5.9±0.4) cm. All patients in this study had I/A wound healing with no perioperative complications such as infection, poor wound healing and fractures of the proximal femur. The average operation time was (65±14) min, and the average amount of blood loss was (136±56) ml. The average acetabular abduction angle and acetabular antegrade inclinations was 41.4°±3.6° and 16.0°±5.3°, respectively. The resting-state VAS of pain at 6 h and 24 h after operation were all ≤2, and there was no significant difference between the VAS scores after exercise and the VAS scores at the resting state (both P>0.05). There was no statistically significant difference between the VAS scores at the same state at different times (both>0.05). The weight-bearing exercise was applied in all patients within 12 h after surgery. The length of postoperative hospital stays varied from 1 to 3 days((2.0±0.9) days). At the 6th-month follow-up, the Harris score of the hip was 94.7±3.0, which significantly improved when compared with that before the operation (35.5±8.1)(P<0.01). No sensory abnormalities were observed. The satisfaction score of the patients was 9.3±0.5 (full score set to 10). Conclusions: The efficacy and safety of the endoscope assisted total hip arthroplasty for total hip replacement is acceptable. This procedure can help to reduce the compression of the muscles by the retractor in the conventional operation. It can be applied to obese and muscular patients.

RESUMO

OBJECTIVE: Our retrospective study aimed to assess the prenatal clinical utility of chromosome microarray (CMA) and the correlations of pathogenic copy number variants (CNVs) with different types of renal abnormalities detected by prenatal ultrasound screening and help to guide the optimal management for the relative late invasive diagnostic approach for renal abnormalities. METHODS: Fetus at 14-36 weeks of gestation were routinely screened for renal and other structural abnormalities at the Maternal and Child Health Hospital of Guangxi Autonomous Region. 877 fetuses with abnormal renal sonographic findings identified over a period of more than five years were subjected for CMA analysis using materials obtained from chorionic villi sampling, amniocentesis or cordocentesis. RESULTS: Renal abnormal cases that were subjected for CMA test constituted 2.44% (877/35,884) of all ultrasound abnormal fetus that were tested by CMA in this single center. The anomalies were diagnosed rather late in this series as 64% of isolated renal anomalies performed cordocentesis rather than CVSs. Ten types of overlapping renal anomalies were reported by prenatal ultrasound screening. Fetal pyelectasis was the most common renal ultrasound finding, it accounted for a third (34.32%, 301/877) of all fetuses with renal anomalies but only 3.65% (isolated case: 2.36% (4/169) and non-isolated case: 5.30% (7/132)) of them harbored pathogenic CNV. Hyperechogenic kidneys accounted for 5.47% of fetuses with renal anomalies, 39.58% (isolated case: 44.44% (16/36) and non-isolated case: 25.00% (3/12)) had pathogenic CNV findings, the highest diagnostic yield among all groups. Renal agenesis which accounted for 9.92% of all abnormal renal cases had a CMA diagnostic yield of 12.64% (isolated case: 11.53% (9/78) and non-isolated case: 22.22% (2/9), unilateral case:11.39% (9/79) and bilateral case: 25.0% (2/8)), whereas multicystic dysplastic kidney (n=110), renal cyst (n=34), renal dysplasia (n=27), crossed fused renal ectopia (n=31), hydronephrosis (n=98), renal duplication (n=42) and ectopic kidney (n=99) had an overall diagnostic rate of 11.81%, 11.76%, 7.40%, 6.45%, 6.12% , 4.76% and 3.03% respectively. The live-and-well infant rate was significantly higher in CMA negative fetuses with isolated fetal pyelectasis and ectopic kidney whereas the rate was significantly lower in fetuses with isolated renal agenesis, multicystic dysplastic kidney and sever hydronephrosis. The most common pathogenic CNV was 17q12 deletion (n=22), which accounted for 30.13% (22/73) of all positive CMA findings with a rate of 2.50% (22/877) among fetus with all abnormal renal findings. Fetuses with 17q12 deletion exhibited a wide range of renal phenotypes. Other recurrent CNVs associated with prenatal renal ultrasound abnormalities were 22q11.2, Xp21.1, Xp22.31, 2q13, 16p11.2, 1q21 which collectively accounted for 2.16% (19/877) of the fetuses with prenatal renal anomalies. CONCLUSION: We retrospectively reviewed the CMA findings for a large cohort of fetus with different types of renal ultrasound abnormalities. The CNV detection rate varied significantly (3.03%-39.58%) among groups. The most consistent ultrasound indication for CMA test would be hyperechogenic kidney. Our data provided specific guidance for ordering prenatal genetic testing for fetus with renal ultrasound findings. Specifically it is more appropriate to perform CMA test for isolated fetal pyelectasis postnatally rather than prenatally via cordocentesis at the third trimester.

RESUMO

Objective: To evaluate the safety and effectiveness of a new Chinese-made surgical biopatch for atrial septum under the establishment of atrial septal defect animal model in miniature pigs. Methods: From June 2018 to April 2019, 26 pigs were divided into experimental group (15 pigs) and the control group (11 pigs). Animal models of atrial septal defect were established by traditional surgical methods. The to-be-evaluated and listed surgical biological patches (with a diameter of 10 mm) were implanted in the experimental group and the control group to repair the atrial septal defect. Cardiac ultrasound and blood examination of all animals were performed before and at 7, 30, 90, 180 days after operation, the results were analyzed with repetitive measurement and analysis of variance. At 90 days and 180 days after the operation, tissue samples were taken from animals after euthanasia. Pathological examination of heart and major organs were conducted. The independent sample t test and rank sum test were used to compare the data between the two groups, and the nonparametric was used to compare the patch calcification score between the two groups. Results: In total of 26 animals, 14 animals in the experimental group(6 at 90 days, 8 at 180 days) and 9 animals in the control group(4 at 90 days, 5 at 180 days) reached the end of the experiment. The other 3 animals (1 in the experimental group and 2 in the control group) died of arrhythmia, whole heart failure and right heart failure, the results of pathological examination showed that the causes of death were unrelated to the experimental materials. Cardiac ultrasound showed no patch leakage in all animals. There was no statistically significant difference in cardiac ultrasound and blood examination between the two groups at different time points after operation (all P>0.05). The pathological results showed that all the implants were intact and had good biocompatibility. There was no significant difference in the mean endothelialization rate between the experimental group and the control group at 90 and 180 days after operation ((80.8±29.1)% vs. (82.5±23.6)%, t=0.095, P=0.927; (78.8±36.4)% vs. (82.0±19.2)%, t=0.182, P=0.859) on 90 and 180 days, there was no significant difference in the patch calcification score between the two groups (1.00(1.25) vs. 2.00(0.75), Z=6.500, P=0.214; 0(0.75) vs. 1.00(2.00), Z=12.000, P=0.139). Conclusion: The new Chinese-made surgical biopatch for atrial septum has comparable safety and efficacy to that of the marketable patch in miniature pig atrial septal defect animal model.

RESUMO

Objective: To comparatively study the similarities and differences between the clinical, pathological, and risk factors of advanced fibrosis in men and women with non-alcoholic fatty liver disease (NAFLD). Methods: 267 patients with NAFLD diagnosed by liver biopsy were retrospectively included, and were divided into male and female groups. The difference of clinical and pathological indexes were compared between the two groups. The measurement data were in accordance with normal distribution. The comparison between the two groups was performed by independent sample t-test. The non-parametric test was used for non-normal distribution. The classification data were expressed as a percentage, and the chi-square test was used for comparison between groups. Logistic regression analysis was used to analyze the risk factors. Results: The age of onset of NAFLD was significantly lower in male than female patients (P < 0.01). There was no statistically significant difference between the male and female groups in terms of body mass index and the prevalence of type 2 diabetes (P > 0.05). Biochemical index: The levels of alanine aminotransferase, albumin, total bilirubin and uric acid were significantly higher in male than female patients (P < 0.01). Liver pathology: The proportion of ballooning degeneration was significantly lower in male than female patients (P < 0.01). There was not statistically significant difference between the two groups in the proportion of steatohepatitis score, non-alcoholic steatohepatitis (52.0% vs. 61.5%, P = 0.283) and advanced liver fibrosis (14.3% vs. 17.8%, P = 0.162). Thrombocytopenia was a common independent risk factor for advanced stage liver fibrosis (OR = 0.984, 0.978~0.989, P < 0.01). Type 2 diabetes was only an independent risk factor for advanced stage liver fibrosis in men (OR = 6.557, 1.667~25.782), P < 0.01). Elevated AST was only an independent risk factor for advanced stage liver fibrosis in women (OR = 1.016, 1.003~1.028, P = 0.012). Conclusion: In NAFLD patients, there are some clinical and pathological differences between genders. Platelets are a common predictor of advanced liver fibrosis in men and women. Type 2 diabetes in men and elevated aspartate aminotransferase in women can be regarded as independent risk factors for advanced liver fibrosis.
