ABSTRACT

Objective:To analyze the genetic etiology and prognosis in fetuses with increased nuchal translucency (NT) in order to assist in the clinical prenatal genetic counseling and diagnosis.Methods:This study retrospectively enrolled 1 658 cases of singleton pregnancy (<35 years old) receiving invasive prenatal diagnosis, including karyotype analysis and/or chromosome microarray analysis or copy number variation (CNV) sequencing, due to NT value ≥2.5 mm in the first trimester in Henan Provincial People's Hospital from August 2014 to December 2021. They were divided into different groups according to the thickness of NT (≥2.5-<3.0, ≥3.0-<3.5, ≥3.5-<4.5, ≥4.5-<5.5, ≥5.5-<6.5 and ≥6.5 mm groups) and abnormal ultrasound findings (isolated increased NT group, increased NT complicated by soft markers/non-severe structural abnormality group and increased NT complicated by severe structural abnormality group). The results of invasive prenatal diagnosis and pregnancy outcomes were compared between different groups using Chi-square test and trend Chi-square test. Results:The detection rates of numerical abnormalities of chromosomes were 15.8% (262/1 658) and 17.6% (252/1 431) when the NT thickness cut-off value were 2.5 mm or 3.0 mm, respectively. Overall, the detection rate of numerical abnormalities of chromosomes increased with thickness of NT ( χ2trend=180.75, P<0.001), ranging from 6.6% (44/671) in the NT≥2.5-<3.5 mm group to 45.6% (113/248) in the NT≥5.5 mm group. The incidence of pathogenic/likely pathogenic CNV(P/LP CNV) did not increased with NT thickness ( χ2trend=3.26, P=0.071), and the highest detection rate was observed in the NT≥4.5-<5.5 mm group (9.0%, 19/211). The detection rate of numerical abnormalities of chromosomes plus P/LP CNV in the isolated NT≥2.5-<3.0 mm group and NT≥3.0-<3.5 mm group were 5.3% (10/188) and 9.6% (36/375), respectively, however, the difference was not statistically significant ( χ2=3.06, P=0.080). The detection rates of numerical abnormalities of chromosomes plus P/LP CNV in the isolated NT≥3.5-<4.5 mm group and NT≥2.5-<3.0 mm complicated by soft markers/ non-severe structural abnormality group were 12.7% (52/410) and 24.1% (7/29), respectively, and the risk were 2.6 times (95% CI: 1.3-5.2) and 5.7 times (95% CI: 2.0-16.4) of the isolated NT≥2.5-<3.0 mm group, respectively. The pregnancy termination rate increased with the NT thickness ( χ2trend=304.42, P<0.001), ranging from 10.8% (23/212) in the NT≥2.5-<3.0 mm group to 90.7% (117/129) in the NT≥6.5 mm group. After exclusion of the pregnancies terminated due to numerical abnormalities of chromosomes and P/LP CNV, 87.6% (862/984) of the fetus with increased NT were born alive. Conclusions:The detection rate of numerical abnormalities of chromosomes increases with the thickness of NT. Invasive prenatal diagnosis is required for non-advance aged singleton pregnant women when fetuses present with isolated NT≥2.5 mm with or without soft markers/structural abnormalities.

ABSTRACT

Objective: To explore the outcome of different treatment strategies in patients with pancreatic cancer with synchronous liver metastasis (sLMPC). Methods: A retrospective analysis of the clinical data and treatment results of 37 patients with sLMPC treated in China-Japan Friendship Hospital was performed from April 2017 to December 2022. A total of 23 males and 14 females were included,with an age(M(IQR)) of 61 (10) years (range: 45 to 74 years). Systemic chemotherapy was carried out after pathological diagnosis. The initial chemotherapy strategy included modified-Folfirinox, albumin paclitaxel combined with Gemcitabine, and Docetaxel+Cisplatin+Fluorouracil or Gemcitabine with S1. The possibility of surgical resection (reaching the standards of surgical intervention) was determined after systemic treatment,and the chemotherapy strategy was changed in the cases of failed initial chemotherapy plans. The Kaplan-Meier method was used to estimate the overall survival time and rate,while Log-rank and Gehan-Breslow-Wilcoxon tests were used to compare the differences of survival curves. Results: The median follow-up time for the 37 sLMPC patients was 39 months,and the median overall survival time was 13 months (range:2 to 64 months) with overall survival rates of 1-,3-,and 5-year of 59.5%,14.7%,and 14.7%,respectively. Of the 37 patients,97.3%(36/37) initially received systemic chemotherapy, 29 completed more than four cycles,resulting in a disease control rate of 69.4% (partial response in 15 cases,stable disease in 10 cases,and progressive disease in 4 cases). In the 24 patients initially planned for conversion surgery,the successful conversion rate was 54.2% (13/24). Among the 13 successfully converted patients,9 underwent surgery and their treatment outcomes were significantly better than those (4 patients) of those who did not undergo surgery (median survival time not reached vs. 13 months,P<0.05). Regarding the 9 patients whose conversion was unsuccessful, no significant differences were observed in median survival time between the surgical group (4 cases) and the non-surgical group (5 cases) (P>0.05). In the allowed-surgery group(n=13),the decreased in pre-surgical CA19-9 levels and the regression of liver metastases were more significant in the successful conversion sub-group than in the ineffective conversion sub-group;however, no significant differences were observed in the changes in primary lesion between the two groups. Conclusion: For highly selective patients with sLMPC who achieve partial response after receiving effective systemic treatment,the adoption of an aggressive surgical treatment strategy can significantly improve survival time;however, surgery dose not provide such survival benefits in patients who do not achieve partial response after systemic chemotherapy.

ABSTRACT

OBJECTIVE@#To explore correlation between imaging classification of knee osteoarthritis (KOA) and axis angle of tibiofemoral and patellofemoral joints.@*METHODS@#A retrospective analysis of 739 middle-aged and elderly patients with KOA (1 026 knee joints) who underwent vertical X-ray examination of both lower limbs and lateral knee joints from September 2018 to December 2020. Among them, 63 patients with K-L 0 grade (95 knee joints), 100 patients with K-L 1 grade (130 knee joints), 161 patients with K-L 2 grade (226 knee joints), 187 patients with K-L 3 grade (256 knee joints), and 228 patients of K-L 4 grade (319 knee joints). According to relative position of knee joint center and line between hip joint center and ankle joint center, the affected knee was divided into varus group(844 knees joints) and valgus group (182 knees joints). According to Install-Salvati method, the affected knee was divided into three groups, such as high patella (patella height>1.2 mm, 347 knees joints), median patella (patella height ranged from 0.8 to 1.2 mm, 561 knees joints), and low patella (patella height<0.8 mm, 118 knees joints). Lower femur angle, upper tibia angle, femoral neck shaft angle, femoral tibial angle, joint gap angle, hip-knee-ankle angle, patella-femoral angle and patella height among different groups were observed and compared.@*RESULTS@#(1) In varus KOA group, there were statistical differnces in hip-knee-ankle angle, tibiofemoral angle, lower femoral angle, upper tibial angle, joint space angle, and femoral neck shaft angle of patients with different K-L grades (P<0.05). Hip-knee-ankle angle, tibiofemoral angle, lower femoral angle, upper tibial angle, joint space angle and K-L grade were significantly positively correlated at 0.01(P<0.05);femoral neck shaft angle and K-L grade showed negative correlation at 0.01(P<0.05). (2) In valgus KOA group, hip-knee-ankle angle, there were statistical differences in tibiofemoral angle, inferior femoral angle, superior tibial angle, joint space angle, and femoral neck shaft angle of patients with different K-L grades(P<0.05). Hip-knee-ankle angle, tibiofemoral angle, lower femoral angle, upper tibial angle, and femoral neck shaft angle showed negative correlation with K-L grades at level of 0.01 (P<0.05);joint gap angle and K-L grades showed significantly positive correlation at level of 0.01(P<0.05). (3) In high patella group, there were statistically differences in patellar height and patellar femoral angle of different K-L grades(P<0.05);there were no statistical difference in patella height and patellar femoral angle of different K-L grades in median patella group. There was no significant difference in patella heightin low patella group with different K-L grades(P>0.05), and there was statistical difference in patellofemoral angle(P<0.05). Patellar height and patella-femoral angle of high patella group were significantly positively correlated with K-L grades at the level of 0.01 (P<0.05);patella height and patella-femoral angle were not correlated with K-L grades in median patella group(P>0.05). There was no correlation between height of patella and K-L grade in low patella group (P>0.05). There was significant negative correlation between patella-femoral angle and K-L grade at level of 0.05 (P<0.05).@*CONCLUSION@#Inferior femoral angle, tibiofemoral angle, joint gap angle, hip-knee-ankle angle, femoral neck shaft angle and high patella are related to K-L classification of varus KOA, which could be used for early diagnosis and provide objective data for efficacy analysis of conservative treatment.

ABSTRACT

ObjectiveTo investigate the clinical efficacy of oral dydrogesterone alone for luteal phase support in natural cycle frozen-thawed embryo transfer (NC-FET). MethodsThe clinical data of 1 530 NC-FET cycles enrolled in our Reproductive Center from January 2019 to September 2021 were retrospectively analyzed. According to different luteal support protocols, the patients were divided into oral dydrogesterone alone (group A, n=524), vaginal progesterone soft capsules (group B, n=401) and vaginal progesterone soft capsules combined with dydrogesterone (group C, n=605). The clinical outcomes and cost-effectiveness ratio were compared among the three groups. The primary outcome was live birth rate. ResultsThe live birth rate was 43.13% (226/524) in group A, 39.15% (157/401) in group B, and 42.64% (258/605) in group C. There was no statistical difference among the three groups (P > 0.05). No statistical difference was observed in the HCG positive rate, implantation rate, biochemical pregnancy rate, clinical pregnancy rate, spontaneous miscarriage rate, ectopic pregnancy rate, twin delivery rate, premature delivery rate and newborn weight among the three groups (P>0.05). Logistic regression analysis revealed that the three luteal support regimens did not affect live birth rate. Pharmacoeconomic analysis showed that taking group B as a reference, the cost increased by 19 227.30 yuan for every 1% increase in live birth rate in group A. ConclusionsIn NC-FET cycle, oral dydrogesterone alone can achieve the same clinical outcomes as vaginal progesterone soft capsules and vaginal progesterone soft capsules combined with dydrogesterone. Compared with that of progesterone soft capsules, the cost of oral dydrogesterone alone is increased, a large sample and multicenter prospective study is needed to further confirm our results.

ABSTRACT

OBJECTIVE@#To explore the genetic etiology of a Chinese pedigree affected with pseudohypoparathyroidism.@*METHODS@#Peripheral blood samples of the proband and his parents were collected and subjected to trio-whole exome sequencing (trio-WES). Candidate variants were verified among the pedigree and 50 randomly selected healthy individuals through analysis of restriction fragment length polymorphism. Short tandem repeat (STR) linkage analysis was used to verify the parental origin of the pathogenic variants.@*RESULTS@#Trio-WES and Sanger sequencing showed that the proband and his mother had both harbored a c.121C>G (p.His41Asp) variant of the GNAS gene, which was not found in other family members and the 50 healthy controls. The variant was not found in international databases. Based on guidelines from the American College of Medical Genetics and Genomics, the variant was predicted to be likely pathogenic.@*CONCLUSION@#The novel c.121C>G variant of the GNAS gene probably underlay the disease in this pedigree. Above finding has enriched the spectrum of GNAS gene variants.

ABSTRACT

Objective:To analyze the pathogenic gene and prenatal diagnosis of a family with intellectual disability.Methods:Out of this family consisting of 17 members in three generations, four males had intellectual disability. The proband's elder sister (Ⅱ-7) visited Henan Provincial People's Hospital in Oct 2019 for genetic counseling at 8 weeks of gestation. After informed consent was obtained, peripheral blood samples of the family members were collected. The whole exome sequencing was performed on the genome DNA of the proband (Ⅱ-9, male) and his parents to screen the candidate variants for phenotype co-segregated analysis by Sanger sequencing. The expression vectors were constructed by homologous recombination and the splicing experiments were performed in vitro. Reverse transcription polymerase chain reaction, Sanger sequencing, and TA clone sequencing were used to analyze the effect of candidate variants on splicing. After the pathogenic variant was determined the proband's elder sister underwent prenatal diagnosis (Ⅲ-7) using goldeneyeTM20A genotyping system and Sanger sequencing. Results:A hemizygous synonymous variant of c.1302G>A (p. S434S) in DLG3 gene was found in the proband by whole exome sequencing, which was carried by his mother (Ⅰ-1) and co-segregated with the phenotype in other family patients. In vitro splicing experiment showed that c.1302G>A variant led to abnormal splicing of 88.24% transcripts, which further resulted in the reading frame shift and protein function impairment. The mutation was not detected in the fetus (Ⅲ-7), who was born alive later and showed no abnormal mental or behavioral development at the age of one and a half year and is still being followed up. Conclusions:The synonymous mutation c.1302G>A in DLG3 gene was the etiopathogenesis of X-linked intellectual disability in this family.

ABSTRACT

Objective:To evaluate the effect of oral iodized oil pills on iodine nutrition and thyroid function of pregnant women in Xinjiang Uygur Autonomous Region (Xinjiang).Methods:From May to July 2017, one county was selected from Ili Prefecture without taking iodized oil pills, Aksu Prefecture taking iodized oil pills once a year, and Kashgar Prefecture taking iodized oil pills twice a year in Xinjiang as survey sites, respectively; 100 pregnant women (evenly distributed in early, middle and late pregnancy) were selected from each survey county, the general data, urine and blood samples were collected, and urinary iodine and thyroid function indicators [free triiodothyronine (FT 3), free thyroxine (FT 4), thyrotropin (TSH), anti thyroglobulin antibody (TgAb), and anti thyroid peroxidase antibody (TPOAb)] were tested. Results:A total of 308 pregnant women were investigated, and 289 were finally included in the analysis, with an average age of 25 years; the body mass index (BMI) was (22.69 ± 3.07) kg/m 2. The occupation distribution was mainly farmer, accounting for 93.77% (271/289); most of them had junior high school education or below, accounting for 71.97% (208/289). The median urinary iodine of early, middle and late pregnant women in Kashgar Prefecture was 712.87, 604.50 and 656.23 μg/L, respectively, which were in iodine excess state. The iodine nutrition level of early pregnant women in Ili Prefecture and Aksu Prefecture was in iodine super suitability state, and the iodine nutrition level of middle and late pregnant women was in the iodine suitability state. The difference of median urinary iodine in early, middle and late pregnancy women between different regions was statistically significant ( Z = 53.02, 49.60, 44.66, P < 0.001). In addition, the urinary iodine of women in Kashgar Prefecture during each pregnancy period was significantly higher than that in Ili Prefecture and Aksu Prefecture ( P < 0.05). There were statistically significant differences in the levels of FT 3 among women in early pregnancy, FT 4 and TSH among women in middle pregnancy between different regions ( F = 4.59, 10.92, Z = 8.61, P < 0.05 or < 0.001). Among them, the level of FT 3 in early pregnancy in Kashgar Prefecture was lower than that in Ili Prefecture ( P < 0.05); the level of FT 4 in Kashgar Prefecture during middle pregnancy was higher than that in Ili Prefecture, and the level of TSH was lower than that in Ili Prefecture ( P < 0.05). There was no significant difference in TgAb positive rate, TPOAb positive rate and double antibody positive rate of early, middle and late pregnant women between different regions ( P > 0.05). The detection rates of hypothyroxinemia in early pregnant women in Ili Prefecture, Aksu Prefecture and Kashgar Prefecture were 13.9% (5/36), 3.2% (1/31) and 0 (0/33), respectively, and there was a statistically significant difference between different regions ( P = 0.036). The detection rates of subclinical hyperthyroidism in middle pregnant women were 0 (0/35), 0 (0/40), 17.6% (6/34), respectively, and there was a statistically significant difference between different regions ( P = 0.001). Conclusions:The results of urinary iodine in the three regions are in line with the iodine nutrition distribution under their respective iodine supplement strategies. Pregnant women in Kashgar Prefecture present iodine excess status after taking iodized oil pills; at the same time, the serum FT 3, FT 4 and TSH levels of pregnant women in Kashgar Prefecture are affected by iodine nutrition levels. Although it is scientific and effective to implement the intensified iodine supplement measures for pregnant women, it is still necessary to further study the suitability of oral iodine oil pills to ensure that pregnant women are at an suitability iodine nutrition level.

ABSTRACT

Objective:To explore the effect of methamphetamine (MA) dependence on the attention of female youth, and to analyze the intervention effect of computer-based cognitive training on the attention of MA-dependent female youth.Method:From May to August 2021, a total of 64 MA-dependent female youths in abstinence period from a women's compulsory isolated drug rehabilitation center in Sichuan Province were selected as the MA group, and 53 ordinary female youths matched with their age and education level were selected as the normal control group.According to the matching principle of age, education level, and attention pre-test scores, the subjects in MA-dependent group were divided into MA-dependent intervention group( n=30)and MA-dependent waiting group( n=34). CogniPlus cognitive training system was used to train the attention of subjects in MA-dependent intervention group( n=30), while the subjects in MA-dependent waiting group( n=34) and normal control group did not receive training.The Vienna Test System was used to collect the attention scores of all subjects.SPSS 20.0 analysis software was used for data processing.Statistical analysis was performed using independent samples t test and paired samples t test. Results:The MA-dependent group had significantly longer endogenous alertness, temporary alertness, and concentration response time ((275.61±47.79)ms, (268.63±51.41)ms, (444.08±134.40)ms) compared with the normal control group ((247.02±34.09)ms, (237.60±46.04)ms, (355.15±44.37)ms) ( t=3.767, 3.405, 4.976; all P<0.05). After attention training, the post-test reaction time of endogenous alertness, temporary alertness, and concentration ((264.10±38.98)ms, (251.67±38.06)ms, (352.03±65.70)ms) in the MA-dependent intervention group were significantly shorter than those in the MA-dependent waiting group ((323.18±83.28)ms, (302.74±82.75)ms, (402.76±74.34)ms) ( t=-3.702, -3.232, -2.876; all P<0.05). The post-test reaction time of temporary alertness and concentration in the MA-dependent intervention group ((251.67±38.06)ms, (352.03±65.70)ms)were shorter than those of the pre-test ((265.70±37.84)ms, (428.67±120.11)ms) ( t=2.179, 3.588; both P<0.05). The MA-dependent waiting group had a longer post-test reaction time of endogenous alertness and temporary alertness(323.18±83.28)ms, (302.74±82.75)ms) compared with the pre-test ((285.35±51.43)ms, (271.21±61.42)ms) ( t=-2.752, -2.664; both P<0.05) and the post-test reaction time of concentration ((402.76±74.34)ms) was shorter than that of the pre-test ((457.68±146.29)ms)( t=2.431, P<0.05). The MA-dependent intervention group had longer endogenous alertness, temporary alertness, and pre-test reaction time of concentration ((264.57±41.41)ms, (265.70±37.84)ms, (428.67±120.11)ms)compared with the normal control group( t=2.083, 2.841, 3.230; all P<0.05). The post-test of endogenous alertness ((264.10±38.98)ms) was longer than that of the normal control group ( t=2.082, P<0.05). Conclusion:The cognitive training based on the CogniPlus system has a certain effect on the attention maintenance or recovery of MA-dependent female youth.It can be used as an intervention measure for cognitive impairment of drug addicts and help them healthy return to society.

ABSTRACT

Objective:To analyze the characteristic of prenatal serological screening in fetus with X-linked ichthyosis (XLI), and to explore the relationship between unconjugated estriol (uE 3) levels and XLI. Methods:A total of 56 fetuses with Xp22.31 microdeletion indicated by prenatal diagnosis and 70 fetuses diagnosed with trisomy 21 and 26 fetuses with trisomy 18 in Henan Provincial People's Hospital and Affiliated Hospital of Weifang Medical College from September 2016 to June 2021 were collected. The multiples of median (MoM) values of uE 3, alpha-fetoprotein (AFP), and human chorionic gonadotropin (hCG) during the second trimester of pregnancy were retrospectively analyzed. Prenatal diagnosis was made by amniotic fluid karyotype analysis and genome copy number variant analysis, parent genetic verification and pathogenicity analysis were performed, and maternal and infant outcomes were followed up. Results:Of 56 pregnant women with fetal Xp22.31 microdeletion, 43 underwent serological screening during the second trimester of pregnancy, of which 42 were abnormal (39 male fetuses and 3 female fetuses). The median uE 3 MoM value of 39 male fetuses [0.06 (0.00-0.21)] was lower than the normal value and significantly lower than that of fetuses with trisomy 21 [0.71 (0.26-1.27)] and fetuses with trisomy 18 [0.36 (0.15-0.84)], the difference was statistically significant ( Z=99.96, P<0.001). While the MoM values of AFP and hCG were all within the normal range. Among the 56 fetuses carrying Xp22.31 microdeletion, 45 were male fetuses and 11 were female fetuses, and the deletion fragments all involved STS gene. Eighty-nine percent (50/56) were inherited from mother (49 cases) or father (1 case), and 11% (6/56) were de novo mutations. Follow-up showed 48 live births (38 males and 10 females) and 8 chose to terminate pregnancy (7 males and 1 female). Among the 38 male newborns, 37 presented with scaly skin changes from 1 to 3 months of age, and one had no clinical manifestations until 4 months after birth. Ten female newborns had no obvious clinical manifestations. Conclusions:The decrease levels of uE 3 MoM on maternal serological screening is closely related to the higher risk of XLI in male fetuses. For pregnant women with low uE 3 in serological screening or with family history of ichthyosis, in addition to chromosomal karyotype analysis, joint detection of genomic copy number variant analysis should be recommended.

ABSTRACT

Objective:To learn about the status of thyroid function and intelligence quotient (IQ) of children in areas with different iodine nutrition levels in Xinjiang Uygur Autonomous Region, and to explore the health risk of children with median urinary iodine of 200 - 299 μg/L, and to provide a basis for scientific iodine supplementation.Methods:In May 2019, in Xinjiang Uygur Autonomous Region, Altay Prefecture and Kashgar Prefecture were selected, where the median urinary iodine of children aged 8 to 10 years were 100 - 199 and 200 - 299 μg/L for three consecutive years (2017 - 2019). A stratified random sampling method was used to select 400 children aged 8 to 10 years in each of the two regions, urine and blood samples were collected to detect urinary iodine and thyroid function [thyrotropin stimulating hormone (TSH), free thyroxine (FT 4), free triiodothyronine (FT 3), anti-thyroglobulin antibody (TgAb), and anti-thyroperoxidase antibody (TPOAb)]. At the same time, children's IQ was measured and determined by Second Revision of Combined Raven's Test (CRT-C2) in China and Second Revision of Combined Raven's Test for Children-the Rural, in China (CRT-RC2). Results:The median urinary iodine of children aged 8 to 10 years in Altay Prefecture and Kashgar Prefecture was 188.6 and 250.1 μg/L, respectively. There was no statistically significant difference in thyroid function indexes TSH and FT 3 levels between the two regions ( Z = - 0.58, t = 0.49, P > 0.05), while there was statistically significant difference in FT 4 level ( t = 60.08, P < 0.001). There was no statistically significant difference in TgAb positive rate [3.6% (14/394), 4.0% (16/399)] between the two regions (χ 2 = 0.11, P = 0.736), but the difference of TPOAb positive rate [9.6% (38/394), 30.6% (122/399)] was statistically significant (χ 2 = 53.93, P < 0.001), while the difference of dual antibody positive rate [0.8% (3/394), 2.0% (8/399)] was not statistically significant ( P = 0.134). There was no statistically significant difference in the detection rates of subclinical hypothyroidism [8.9% (35/394), 11.0% (44/399)], subclinical hyperthyroidism [1.0% (4/394), 1.3% (5/399)] and hyperthyroidism [0.3% (1/394), 0.8% (3/399)] in children between the two regions ( P > 0.05). The IQ results of children in the two regions were 96.55 ± 11.36 and 89.57 ± 12.35, respectively, and there was no significant difference between them ( t = 2.79, P = 0.095). Conclusions:The thyroid function status of children is similar in the two regions with median urinary iodine of 100 - 199 μg/L and 200 - 299 μg/L in children aged 8 to 10 years, but the TPOAb positive rate is significantly different. Children whose iodine nutritional level is at or above the appropriate level have no obvious changes in intelligence. It is suggested that median urinary iodine at 200 - 299 μg/L is a relatively safe iodine nutrition state.

ABSTRACT

Objective: To investigate the effect of visceral fat area (VFA) on the surgical efficacy and early postoperative complications of radical gastrectomy for gastric cancer. Methods: A retrospective cohort study method was used. Clinicopathological data and preoperative imaging data of 195 patients who underwent D2 radical gastric cancer surgery at the First Affiliated Hospital of Xi'an Jiaotong University from January 2014 to December 2017 were analyzed retrospectively. Inclusion criteria: (1) complete clinicopathological and imaging data; (2) malignant gastric tumor diagnosed by preoperative pathology, and gastric cancer confirmed by postoperative pathology; (3) no preoperative complications such as bleeding, obstruction or perforation, and no distant metastasis. Those who had a history of abdominal surgery, concurrent malignant tumors, poor basic conditions, emergency surgery, palliative resection, and preoperative neoadjuvant therapy were excluded. The VFA was calculated by software and VFA ≥ 100 cm2 was defined as visceral obesity according to the Japan Obesity Association criteria . The patients were divided into high VFA (VFA-H, VFA≥100 cm2, n=96) group and low VFA (VFA-L, VFA<100 cm2, n=99) group . The clinicopathological characteristics, surgical outcomes and early postoperative complications were compared between the two groups. Univariate and multivariate Logistic regression models were used to analyze the risk factors of early complications. Receiver operating characteristic (ROC) curve was used to analyze predictive values of VFA for early complications. Pearson's χ2 test was used to analyze the correlation between BMI and VFA. Results: There were no significant differences in terms of gender, age, American Society of Anesthesiologists physical status classification, preoperative comorbidities, preoperative anemia, tumor TNM staging, N staging, T staging and tumor differentiation, surgical method, extent of resection, and tumor location between the VFA-L group and the VFA-H group (all P>0.05). However, patients in the VFA-H group had higher BMI, larger tumor, lower rate of hypoalbuminemia and greater subcutaneous fat area (SFA) (all P<0.05). The VFA-H group presented significantly longer operation time and significantly less number of harvested lymph nodes as compared to the VFA-L group (both P<0.05). However, there were no significant differences in intraoperative blood loss, conversion to laparotomy and postoperative hospital stay (all P>0.05). Complications of Clavien-Dindo grade II and above within 30 days after operation were mainly anastomosis-related complications (leakage, bleeding, infection and stricture), intestinal obstruction and incision infection. The VFA-H group had a higher morbidity of early complications compared to the VFA-L group [24.0% (23/96) vs 10.1% (10/99), χ2=6.657, P=0.010], and the rates of anastomotic complications and incision infection were also higher in the VFA group [10.4% (10/96) vs. 3.0% (3/99), χ2=4.274, P=0.039; 7.3% (7/96) vs. 1.0% (1/99), P=0.033]. Multivariate logistic analysis showed that high BMI (OR=3.688, 95%CI: 1.685-8.072, P=0.001) and high VFA (OR=2.526, 95%CI: 1.148-5.559,P=0.021) were independent risk factors for early complications. The area under the ROC curve (AUC) of VFA for predicting early complications was 0.645, which was higher than that of body weight (0.591), BMI (0.624) and SFA (0.626). Correlation analysis indicated that there was a significantly positive correlation between BMI and VFA (r=0.640, P<0.001). Conclusion: VFA ≥ 100 cm2 is an independent risk factor for early complications after radical gastrectomy for gastric cancer.It can better predict the occurrence of above early postoperative complications.

ABSTRACT

Objective@#To examine the effect of chronic exposure to sodium arsenite on liver damages in rats. @*Methods@#Fifty-six healthy adult SD rats (28 males and 28 females) were randomly divided into 4 groups. Rats in the low-, medium- and high-dose groups were given sodium arsenite solutions at doses of 2, 10 and 50 mg/L for successive 24 weeks, while animals in the control group were given deionized water. The rat body and liver weights were measured and the liver coefficient was estimated. The urine arsenic level was detected using atomic fluorescence spectrometry, and hepatic tissue sections were stained with uranium acetate and lead citrate for morphological observations under an electron microscope. @*Results@#The body weights of both male and female rats appeared a tendency towards a rise with the duration of exposure to sodium arsenite (male rat: Wald χ2=3 610.621, P<0.001; female rat: Wald χ2=2 186.217, P<0.001, and there were no significant differences in the rat body weight 24 weeks post-exposure to sodium arsenite in each group, while there was an interaction between time and group (male rat: Wald χ2=15.874, P=0.001; Wald χ2=9.460, P=0.024). There were significant differences in the rat liver weight and liver coefficient in each group (male rat: F=18.964 and 29.968, both P<0.001; female rat: F=11.919 and 15.070, both P<0.001), with the lowest liver weight (10.17±1.15) g and liver coefficient (1.99±0.21)% measured in male rats in the high-dose group, and the highest liver weight (12.91±1.29) g and liver coefficient (4.10±0.56)% in female rats in the high-dose group. The median urine arsenic levels (interquartile range) were 25.60 (30.27), 146.56 (101.06), 1 034.68 (600.06) and 3 796.98 (19 966.89) μg/L in rats in the control, low-dose, medium-dose and high-dose groups, respectively (χ2=50.211, P<0.001), and the urine arsenic level was significantly higher in the medium- and high-dose groups than in the control group (both P<0.001). Hepatic edema was seen in rats in the low- and medium-dose groups, and hepatic edema, focal hepatic cell necrosis, hyperplasia of bile capillaries and peri-bile capillary endolysis were observed in rats in the high-dose group.@*Conclusions@#Chronic exposure to arsenic may cause morphological alterations of rat hepatic tissues, and the rat hepatic damage aggravates with the dose of exposure to arsenic.

ABSTRACT

ObjectiveTo investigate the characteristics of pelvic floor structure and electrophysiology in female patients with stroke. MethodsFrom June to December, 2020, 21 female inpatients with stroke in Zhongda Hospital, Southeast University (stroke group) were divided into urinary incontinence (UI) group (n = 6) and non-urinary incontinence (NUI) group (n = 15), and other 20 healthy subjects were as control group. They were observed with pelvic floor ultrasonography and pelvic floor surface electromyogram. ResultsAverage electromyography, integral electromyography, root mean square, mean power frequency and median frequency decreased in UI and NUI groups compared with those of the control group (P < 0.05), but there was no significant difference between UI group and NUI group (P > 0.05). Bladder neck position, bladder neck angle, bladder neck mobility, urethral rotation angle; and anteroposterior diameter, left-right diameter and area of levator ani muscle hiatus after Valsalva's action were all not different among three groups (F < 2.484, P > 0.05). ConclusionThe activities of pelvic floor muscles decrease in female patients with stroke, without obvious changes of pelvic floor supporting structures, whatever UI.

ABSTRACT

Objective: To compare clinical efficacy between laparoscopic radical proximal gastrectomy with double-tract reconstruction (LPG-DTR) and laparoscopic radical total gastrectomy with Roux-en-Y reconstruction (LTG-RY) in patients with early upper gastric cancer, and to provide a reference for the selection of surgical methods in early upper gastric cancer. Methods: A retrospective cohort study method was carried out. Clinical data of 80 patients with early upper gastric cancer who underwent LPG-DTR or LTG-RY by the same surgical team at the Department of General Surgery, the First Affiliated Hospital of Xi'an Jiaotong University from January 2018 to January 2021 were retrospectively analyzed. Patients were divided into the DTR group (32 cases) and R-Y group (48 cases) according to surgical procedures and digestive tract reconstruction methods. Surgical and pathological characteristics, postoperative complications (short-term complications within 30 days after surgery and long-term complications after postoperative 30 days), survival time and nutritinal status were compared between the two groups. For nutritional status, reduction rate was used to represent the changes in total protein, albumin, total cholesterol, body mass, hemoglobin and vitamin B12 levels at postoperative 1-year and 2-year. Non-normally distributed continuous data were presented as median (interquartile range), and the Mann-Whitney U test was used for comparison between groups. The χ(2) test or Fisher's exact test was used for comparison of data between groups. The Mann-Whitney U test was used to compare the ranked data between groups. The survival rate was calculated by Kaplan-Meier method categorical, and compared by using the log-rank test. Results: There were no statistically significant differences in baseline data betweeen the two groups, except that patients in the R-Y group were oldere and had larger tumor. Patients of both groups successfully completed the operation without conversion to laparotomy, combined organ resection, or perioperative death. There were no significant differences in the distance from proximal resection margin to superior margin of tumor, postoperative hospital stay, time to flatus and food-taking, hospitalization cost, short- and long-term complications between the two groups (all P>0.05). Compared with the R-Y group, the DTR group had shorter distal margins [(3.2±0.5) cm vs. (11.7±2.0) cm, t=-23.033, P<0.001], longer surgery time [232.5 (63.7) minutes vs. 185.0 (63.0) minutes, Z=-3.238, P=0.001], longer anastomosis time [62.5 (17.5) minutes vs. 40.0 (10.0) minutes, Z=-6.321, P<0.001], less intraoperative blood loss [(138.1±51.6) ml vs. (184.3±62.1) ml, t=-3.477, P=0.001], with significant differences (all P<0.05). The median follow-up of the whole group was 18 months, and the 2-year cancer-specific survival rate was 97.5%, with 100% in the DTR group and 95.8% in the R-Y group (P=0.373). Compared with R-Y group at postoperative 1 year, the reduction rate of weight, hemoglobin and vitamin B12 were lower in DTR group with significant differences (all P<0.05); at postoperative 2-year, the reduction rate of vitamin B12 was still lower with significant differences (P<0.001), but the reduction rates of total protein, albumin, total cholesterol, body weight and hemoglobin were similar between the two groups (all P>0.05). Conclusions: LPG-DTR is safe and feasible in the treatment of early upper gastric cancer. The short-term postoperative nutritional status and long-term vitamin B12 levels of patients undergoing LPG-DTR are superior to those undergoing LTG-RY.

ABSTRACT

OBJECTIVE@#To analyze the genomic variation characteristics of fetal with abnormal serological screening, and to further explore the value of copy number variation (CNV) detection technology in prenatal diagnosis of fetal with abnormal serological screening.@*METHODS@#7617 singleton pregnant women who underwent amniocentesis for prenatal diagnosis solely due to abnormal Down's serological screening were selected. According to the results of serological screening, the patients were divided into high risk group, borderline risk group and single abnormal multiple of median (MOM) group. CMA and CNV-Seq were used to detect the copy number variation of amniotic fluid cell genomic DNA and combined with amniotic fluid cell karyotype analysis for prenatal diagnosis. Outpatient revisit combined with telephone inquiry was used for postnatal follow-up.@*RESULTS@#Among 7617 amniotic fluid samples, aneuploidy was detected in 138cases (1.81%) by CMA and CNV-Seq, 9 cases of aneuploid chimerism were detected by amniotic fluid cell karyotype analysis, and 203 cases of fetus carrying pathogenic and likely pathogenic CNV (P/LP CNV) were detected, the variant of uncertain significance (VUS) was detected in 437 cases (5.7%), the overall abnormal detection rate was 10.33%. The detection rate of aneuploidy by CMA and CNV-Seq in three group were 123 cases (2.9%), 13 cases (1.3%) and 2 cases (0.4%), respectively,and showing no significant difference (χ 2=7.469, P=0.024). The detection rate of pathogenic and likely pathogenic CNV in three group were 163cases (2.6%); 24 cases (2.6%) and 16 cases (3.3%), respectively, and showing no significant difference (χ 2=0.764, P=0.682). The CMA reported 2.9% (108/3729)P/LP CNV, and CNV-seq reported 2.4% (95/3888)P/LP CNV, both tests showed similar detective capabilities (χ 2=1.504, P=0.22).The most popular P/LP CNV in this cohort were Xp22.31 microdeletion, 16p13.11 microduplication /microdeletion, 22q11.21 microduplication /microdeletion. In fetuses with P/LP CNV CNV, 59 fetuses were terminated pregnancy, and 32 of 112 fetuses born had abnormal clinical manifestations. Non-medically necessary termination of pregnancy occurred in 11 fetuses carrying VUS CNV, 322 fetuses carrying VUS CNV were born, 4 of them presented abnormal clinical manifestations.@*CONCLUSION@#Compared with the traditional chromosome karyotype, CMA and CNV-Seq can improve the detection rate of pathogenic and likely pathogenic CNV. CMA and CNV-seq can be used for first tier diagnosis of pregnant women in the general population with abnormal Down's serological screening.
