ABSTRACT

AIM: To investigate the characteristics of anterior segment structure in first-degree relatives of patients with primary angle-closure glaucoma(PACG).METHODS: A total of 48 first-degree relatives of PACG patients aged 40-60 who were treated in the Affiliated Eye Hospital of Nanchang University from September 2020 to October 2022 were selected as the observation group. Additionally, 40 cases(40 eyes)of healthy individuals without glaucoma and family history of glaucoma at the same age group were collected as the control group. They were divided into younger group(40-49 years old)and elder group(50-60 years old). All subjects were examined with ultrasound biomicroscopy(UBM)and were measured using camera measure software. The parameters mainly included anterior chamber depth(ACD), anterior chamber area(ACA), anterior chamber width(ACW), anterior segment depth(ASD), angle open distance(AOD500), trabecular iris angle(TIA), trabecular iris area(TISA500), lens vault(LV), iris curve(IC), iris thickness(IT500), scleral ciliary process angle(SCPA), and iris ciliary process distance(ICPD).RESULTS: ACD, ACA, AOD500, TISA500 and TIA in the observation group were lower than those of the control group, and LV and IC were higher than those of the control group(all P<0.05). ACD, ACA, AOD500, TISA500, and TIA of the elder group were lower than those in the age-matched control group, while LV and IC were larger than those of the age-matched control group(all P<0.05). ACD, AOD500, TISA500, and TIA of the younger observation group were smaller than those of the age-matched control group, but LV and IC were significantly larger than those of the age-matched control group(all P<0.05). ACD, ACA, AOD500, TISA500 and TIA of the elder observation group were significantly lower than those of the younger observation group, and LV and IC were significantly larger than those of the younger observation group(all P<0.05). There was a difference in the distribution of ACD between the observation group and the control group(P<0.05), and the proportion of moderate to severe shallow anterior chambers was 10 times that of the control group. Correlation analysis showed that TISA500 was positively correlated with ACD and ACA, and negatively correlated with LV and IC, and TISA500 was mainly influenced by LV. IC had a positive correlation with LV and a negative correlation with ACD and ACA.CONCLUSION: First-degree relatives of PACG with normal axial length have a high risk of angle closure. The anterior segment structures of first-degree relatives of PACG are more crowded than normal individuals, and the lens forward shift may be the initial influencing factor for narrow angle.

ABSTRACT

Objective:To evaluate the value of CEA, CYFRA21-1 and CA125 tests in opportunistic screening of non-small cell lung cancer (NSCLC) based on meta-analysis.Methods:The original research literatures on the diagnostic value of CEA, CYFRA21-1 and CA125 in Chinese NSCLC patients were searched from databases of PubMed, Embase, The Cochrane Library, CNKI, VIP, Database and Wanfang database from establishment to June 2023. The literature screening, data extraction and quality evaluation were carried out independently by two researchers. The quality evaluation tool of diagnostic accuracy studies was used to evaluate the quality of the literature. A summary receiver operating characteristic (SROC) curve was used to assess the overall effectiveness of the tests. The outcome stability and publication bias were detected by using sensitivity analysis and Deeks′ test.Results:A total of 23 studies met the inclusion and exclusion criteria were included. The results of meta-analysis showed that the overall sensitivity of CEA, CYFRA21-1 and CA125 alone in the diagnosis of NSCLC was relatively low, it was 0.49(95% CI: 0.43-0.55), 0.56(95% CI: 0.49-0.63) and 0.41(95% CI: 0.33-0.49), respectively. The overall sensitivity of the combined detection of the three markers for the diagnosis of NSCLC increased to 0.83(95% CI: 0.69-0.91), but the overall specificity decreased to 0.76(95% CI: 0.69-0.83). Conclusions:The single detection of CEA, CYFRA21-1 and CA125 is not recommended for screening NSCLC in population receiving physical examination. Although the sensitivity of the combined detection of CEA, CYFRA21-1 and CA125 for screening NSCLC is improved, but the specificity is decreased, the misdiagnosis rate is increased, so the screening effect is limited.

ABSTRACT

Objective:To investigate the behavioral, electroencephalographic, and cognitive functional differences in drug-resistant epileptic rat models of cognitive impairment prepared by intraperitoneal injection of lithium chloride-pilocarpine followed by intracranial injection of pilocarpine or carbamylcholine.Methods:One hundred and sixty adult male SD rats were randomly divided into normal control group ( n=10), lithium chloride-pilocarpine group (establishing epileptic rat models by intraperitoneal injection of lithium chloride-pilocarpine, n=50), pilocarpine-pilocarpine group (intracranial injection of pilocarpine after intraperitoneal injection of lithium chloride-pilocarpine, n=50)and pilocarpine-carbamylcholine group (intracranial injection of carbamylcholine after intraperitoneal injection of lithium chloride-pilocarpine, n=50). Frequency and duration of spontaneously recurrent seizures (SRSs) were observed by video monitoring system, and 2 weeks after that, phenobarbital and phenytoin sodium were injected intraperitoneally to screen drug-resistant models. Frequency and amplitude of the epileptic waves in EEG were recorded by BL-420 Bio-signal Acquisition and Processing System. Novel object recognition experiment was used to detect the novel exploration, Y-maze free exploration experiment and new and different arm experiment were used to detect the spatial recognition and memory ability, and Morris water maze experiment was used to detect the spatial memory ability. Results:(1) Twenty-four rats (48.00%) survived in the lithium chloride-pilocarpine group, 25 (78.00%) in the pilocarpine-pilocarpine group, and 21 (65.62%) in the pilocarpine-carbamylcholine group; and ultimately 7, 9, and 8 drug-resistant epileptic rat models were identified, respectively; frequency and duration of SRSs in the pilocarpine-pilocarpine group and pilocarpine-carbamylcholine group were significantly higher/longer than those in the lithium chloride-pilocarpine group ( P<0.05). (2) The pilocarpine-pilocarpine group and pilocarpine-carbamylcholine group had significantly higher amplitude of the epileptic waves in EEG compared with the lithium chloride-pilocarpine group ( P<0.05); the frequency of the epileptic waves in EEG increased gradually in the lithium chloride-pilocarpine group, pilocarpine-pilocarpine group, and pilocarpine-carbamylcholine group ( P<0.05). (3) Discrimination index, accuracy, ratio of distance traveled in novel arm to total distance, and time of novel arm entries gradually decreased in the normal control group, lithium chloride-pilocarpine group, pilocarpine-pilocarpine group, and pilocarpine-carbamylcholine group, with significant differences ( P<0.05). (4) Compared with the normal control group, the pilocarpine-pilocarpine group and pilocarpine-carbamylcholine group had significantly decreased frequency in crossing the original platform ( P<0.05); compared with the normal control group, lithium-pilocarpine chloride group and pilocarpine-pilocarpine group, the pilocarpine-carbamylcholine group had statistically shorter distance of target quadrant activity ( P<0.05); number of entries in the target quadrant gradually decreased in the normal control group, lithium chloride-pilocarpine group, pilocarpine-pilocarpine group, and pilocarpine-carbamylcholine group, with significant differences ( P<0.05). Conclusion:Drug-resistant epileptic rat models established by intracranial injection of carbamylcholine after intraperitoneal injection of lithium chloride-pilocarpine have high survival rate, high SRSs rate, and severe cognitive impairment, which is suitable for studying drug-resistant epilepsy combined with cognitive impairment.

ABSTRACT

OBJECTIVE@#To analyze and compare the characteristics and causes of F wave changes in patients with Charcot-Marie-Tooth1A (CMT1A) and chronic inflammatory demyelinating polyneuropathy (CIDP).@*METHODS@#Thirty patients with CMT1A and 30 patients with CIDP were enrolled in Peking University Third Hospital from January 2012 to December 2018. Their clinical data, electrophysiological data(nerve conduction velocity, F wave and H reflex) and neurological function scores were recorded. Some patients underwent magnetic resonance imaging of brachial plexus and lumbar plexus, and the results were analyzed and compared.@*RESULTS@#The average motor conduction velocity (MCV) of median nerve was (21.10±10.60) m/s in CMT1A and (31.52±12.46) m/s in CIDP. There was a significant difference between the two groups (t=-6.75, P < 0.001). About 43.3% (13/30) of the patients with CMT1A did not elicit F wave in ulnar nerve, which was significantly higher than that of the patients with CIDP (4/30, 13.3%), χ2=6.65, P=0.010. Among the patients who could elicit F wave, the latency of F wave in CMT1A group was (52.40±17.56) ms and that in CIDP group was (42.20±12.73) ms. There was a significant difference between the two groups (t=2.96, P=0.006). The occurrence rate of F wave in CMT1A group was 34.6%±39%, and that in CIDP group was 70.7%±15.2%. There was a significant difference between the two groups (t=-5.13, P < 0.001). The MCV of median nerve in a patient with anti neurofascin 155 (NF155) was 23.22 m/s, the latency of F wave was 62.9-70.7 ms, and the occurrence rate was 85%-95%. The proportion of brachial plexus and lumbar plexus thickening in CMT1A was 83.3% (5/6) and 85.7% (6/7), respectively. The proportion of brachial plexus and lumbar plexus thickening in the CIDP patients was only 25.0% (1/4, 2/8). The nerve roots of brachial plexus and lumbar plexus were significantly thickened in a patient with anti NF155 antibody.@*CONCLUSION@#The prolonged latency of F wave in patients with CMT1A reflects the homogenous changes in both proximal and distal peripheral nerves, which can be used as a method to differentiate the CIDP patients characterized by focal demyelinating pathology. Moreover, attention should be paid to differentiate it from the peripheral neuropathy caused by anti NF155 CIDP. Although F wave is often used as an indicator of proximal nerve injury, motor neuron excitability, anterior horn cells, and motor nerve myelin sheath lesions can affect its latency and occurrence rate. F wave abnormalities need to be comprehensively analyzed in combination with the etiology, other electrophysiological results, and MRI imaging.

ABSTRACT

AIM: To investigate the efficacy and safety of dacryocystorhinostomy(DCR)through nasal endoscope with extended bone window and high ostomy in the treatment of chronic dacryocystitis.METHODS: Retrospective clinical study. A total of 50 patients(59 eyes)diagnosed with chronic dacryocystitis in our hospital from January 2018 to January 2020 were selected. They were divided into two groups according to the operation method, with 23 cases(29 eyes)in the simple stoma group and 27 cases(30 eyes)in the improved group. Patients in the simple stoma group were treated with transnasal endoscopic flat middle turbinate axillary DCR(simple stoma), and patients in the improved group were treated with transnasal endoscopic extended bone window with high-level stoma DCR. The total clinical efficiency, postoperative complication rate and satisfaction of the two groups were compared.RESULTS: The effective rate of the simple stoma group was 79% at 12mo after surgery, while that of the improved group was 97%(P=0.039). The total incidence of complications in the simple stoma group was 28%, while that in the improved group was 7%(P=0.042). The satisfaction rate of the simple stoma group was 65%, while that of the improved group was 93%(P=0.030).CONCLUSION: The treatment of chronic dacryocystitis with transnasal endoscopic extended bone window and high-level ostomy DCR further improved the efficiency of surgery and reduced the incidence of complications.

ABSTRACT

The purpose of this paper is to review the relationship between dietary inflammatory index and mental disorders, so as to provide references for nutritional interventions for patients with mental disorders. The high disability rate and intractability of mental illness bring huge economic burden and medical pressure to patients' families and society. Dietary nutrition is crucial to the rehabilitation of mental illness. As a new type of index to measure food pro-inflammatory index, dietary inflammatory index is closely related to the occurrence and development of mental illness. Therefore, this paper reviews the development, calculation and correlation with mental illness of dietary inflammatory index.

ABSTRACT

Objective: To determine the efficacy of eltrombopag for primary immune thrombocytopenia (ITP) in adults and the predictive factors for treatment-free response (TFR) . Methods: Clinical data of adults with ITP who received eltrombopag from June 14, 2013 to May 31, 2021 in the Hematology Department of Ruijin Hospital affiliated with Shanghai Jiao Tong University Medical College were retrospectively analyzed. The initial dose of eltrombopag was 25 mg/d, and the maximum dose was 75 mg/d; the dose was adjusted to maintain the platelet count to within 50-150×10(9)/L. Treatment was discontinued according either to the protocol, on the patient's wishes or doctor's judgment (prescription medication), or based on clinical trials. The efficacy of eltrombopag and factors for TFR among patients who achieved complete response and those who discontinued treatment were analyzed. Results: Overall, 106 patients with ITP (33 men and 73 women) were included in the study. The median age of patients was 50 (18-89) years. There were 2, 10, and 94 cases of newly diagnosed, persistent, and chronic ITP, respectively. The complete response rate was 44.3% (47/106), the response rate was 34.0% (36/106), and the overall response rate was 78.3% (83/106). Meanwhile, 83 patients who responded to treatment discontinued eltrombopag; of these, 81 patients were evaluated. Additionally, 17 patients (21.0%) achieved TFR. The median follow-up duration of patients who achieved TFR was 126 (30-170) weeks. The recurrence rate was 17.6% (3/17), and the relapse-free survival rate was 76.5%. The results of univariate analysis revealed that non-recurrence after discontinuation of other treatments for ITP (P=0.001), and platelet count and eltrombopag dose of ≥100×10(9)/L (P=0.007) and ≤25 mg/d (P=0.031), respectively, upon discontinuation of eltrombopag were predictors of TFR; these effects were attributed to prolonged effective duration of eltrombopag. Multivariate analysis showed that there was a correlation between non-recurrence and prolonged effective duration after discontinuation of other treatments for ITP (P=0.002) . Conclusion: Eltrombopag is effective for patients with ITP as it can result in TFR. Predictors for TFR include non-recurrence after discontinuation of concomitant ITP treatment, and platelet count and eltrombopag dose of ≥100 × 10(9)/L and ≤25 mg/d upon discontinuation of treatment, respectively.

ABSTRACT

The purpose of this study was to explore transrectal ultrasound (TRUS) findings of prostate cancer (PCa) guided by multiparametric magnetic resonance imaging (mpMRI) and to improve the Prostate Imaging Reporting and Data System (PI-RADS) system for avoiding unnecessary mpMRI-guided targeted biopsy (TB). From January 2018 to October 2019, fusion mpMRI and TRUS-guided biopsies were performed in 162 consecutive patients. The study included 188 suspicious lesions on mpMRI in 156 patients, all of whom underwent mpMRI-TRUS fusion imaging-guided TB and 12-core transperineal systematic biopsy (SB). Univariate analyses were performed to investigate the relationship between TRUS features and PCa. Then, logistic regression analysis with generalized estimating equations was performed to determine the independent predictors of PCa and obtain the fitted probability of PCa. The detection rates of PCa based on TB alone, SB alone, and combined SB and TB were 55.9% (105 of 188), 52.6% (82 of 156), and 62.8% (98 of 156), respectively. The significant predictors of PCa on TRUS were hypoechogenicity (odds ratio [OR]: 9.595, P = 0.002), taller-than-wide shape (OR: 3.539, P = 0.022), asymmetric vascular structures (OR: 3.728, P = 0.031), close proximity to capsule (OR: 3.473, P = 0.040), and irregular margins (OR: 3.843, P = 0.041). We propose subgrouping PI-RADS score 3 into categories 3a, 3b, 3c, and 3d based on different numbers of TRUS predictors, as the creation of PI-RADS 3a (no suspicious ultrasound features) could avoid 16.7% of mpMRI-guided TBs. Risk stratification of PCa with mpMRI-TRUS fusion imaging-directed ultrasound features could avoid unnecessary mpMRI-TBs.

ABSTRACT

AIM: To compare the clinical efficacy of conbercept and aflibercept in the treatment of wet age-related macular degeneration(wARMD)based on 4 consecutive intravitreal injections.METHODS: The clinical data of 108 patients(108 eyes)who were diagnosed as wARMD and treated with intravitreal injection at our hospital from January 2019 to January 2021 were retrospectively analyzed. They were divided into conbercept group(54 cases, 54 eyes)and aflibercept group(54 cases, 54 eyes)according to the different injectable drugs. All patients received intravitreal injection once a month, with four consecutive injections. Follow up for 12mo to observe best corrected visual acuity(BCVA), central macular thickness(CMT), complications and recurrence before and after injection.RESULTS: BCVA and CMT of patients in the two groups at 1, 2, 5 and 8mo after injection had no between-group differences(P&#x0026;#x003E;0.05), but both were significantly improved compared with those before injection(P&#x0026;#x003C;0.05). By the end of follow-up, conjunctival hemorrhage occurred in 2 eyes of the conbercept group at the early stage, and increased intraocular pressure and conjunctival hemorrhage occurred respectively in 2 eyes of the aflibercept group. There were no serious complications related to drug injection such as retinal detachment, complicated cataract, endophthalmitis and retinal pigment epithelial tear in the two groups, and there was no difference in the recurrence rate between the two groups(7% vs. 6%, P=1.000).CONCLUSION: On the basis of continuous 4 times of intravitreal injection, both conbercept and aflibercept are safe and effective in the treatment of wARMD, and the efficacy is even.

ABSTRACT

The purpose of this study was to evaluate the diagnostic performance of multiparametric ultrasound (mpUS; grayscale US, color Doppler US, strain elastography, and contrast-enhanced US) in the assessment of testicular lesions with negative tumoral markers. MpUS imaging data, patient age, serum tumor markers, scrotal pain, cryptorchidism, and related clinical information were retrospectively collected for patients who underwent mpUS examination between January 2013 and December 2019. Histologic results or follow-up examinations were used as the reference standard. In total, 83 lesions from 79 patients were included in the analysis. Fifty-six patients were finally diagnosed with benign tumors, and 23 patients were ultimately diagnosed with malignant tumors. Chi-square tests or Fisher's exact tests were used to assess the difference between the two groups. Stepwise multivariate logistic regression analysis showed that lesion diameter (odds ratio [OR] = 1.072, P = 0.005), vascularization on color Doppler US (OR = 4.066, P = 0.001), and hyperenhancement during the early phase (OR = 6.465, P = 0.047) were significant independent risk factors for malignancy; however, when compared with neoplastic lesions, pain (OR = 0.136, P < 0.001), absence of vascularization on color Doppler US (OR = 1.680, P = 0.042), and nonenhancement during the late phase (OR = 3.461, P = 0.031) were strongly associated with nonneoplastic lesions. MpUS features are useful for differentiating testicular lesions with negative tumoral markers and improving the preoperative diagnosis, which may avoid inappropriate radical orchiectomy.

ABSTRACT

Objective: To investigate the clinicopathological features, immunophenotype, molecular features and differential diagnosis of primary synovial sarcoma of the lung (PSSL). Methods: Twelve cases of PSSL were collected at Henan Provincial People's Hospital, during May 2010 and April 2021, and their clinicopathological parameters were summarized. SS18-SSX, H3K27Me3, and SOX2 were added to the original immunomarkers to evaluate their diagnostic value for PSSL. Results: The age of 12 patients when diagnosed ranged from 32 to 75 years (mean of 50 years). There were 7 males and 5 females, 2 left lung cases and 10 right lung cases. Of the 6 patients who underwent surgical resection, five cases were confined to lung tissue (T1), one case had mediastinal invasion (T3), two cases had regional lymph node metastasis (N1), and none had distal metastasis. Microscopically, 11 cases showed monophasic spindle cell type and one case showed biphasic type composed of mainly epithelial cells consisting of cuboidal to columnar cells with glandular and cribriform structures. It was difficult to make the diagnosis by using the biopsy specimens. Immunohistochemistry (IHC) showed CKpan expression in 8 of 12 cases; EMA expression in 11 of 12 case; TLE1 expression in 8 of 12 cases; S-100 protein expression in two of 12 cases; various expression of bcl-2 and vimentin in 12 cases, but no expression of SOX10 and CD34 in all the cases. The Ki-67 index was 15%-30%. The expression of SS18-SSX fusion antibody was diffusely and strongly positive in all 12 cases. SOX2 was partially or diffusely expressed in 8 of 12 cases, with strong expression in the epithelial component. H3K27Me3 was absent in 3 of 12 cases. SS18 gene translocation was confirmed by fluorescence in situ hybridization (FISH) test in all 12 samples. Six cases underwent surgery and postoperative chemotherapy, while the other six cases had chemotherapy alone. Ten patients were followed up after 9-114 months, with an average of 41 months and a median of 26 months. Five patients survived and five died of the disease within two years. Conclusions: PSSL is rare and has a broad morphological spectrum. IHC and molecular tests are needed for definitive diagnosis. Compared with current commonly used IHC markers, SS18-SSX fusion antibody has better sensitivity to PSSL, which could be used as an alternative for FISH, reverse transcription-polymerase chain reaction or next generation sequencing in the diagnosis of PSSL.

ABSTRACT

Objective Liver transplantation for colorectal cancer patient with liver metastasis has acquired satisfying result,increasing overall survival in selected patients.The scarcity of grafts is a major obstacle in the field of transplant oncology.The use of small segmental auxiliary grafts from deceased or living donors might be a way to expand the donor pool with minimal negative impact for patient on the waiting list for deceased donor transplantation and minimal risk for living donor.RAPID(re-section and partial liver segment 2/3 transplantation with delayed total hepatectomy)procedure combines the advantages of both ALPPS(associating liver partition and portal ligation for staged hepatectomy)and auxiliary liver transplantation and further ex-panded the field of transplant oncology,bringing hope to long term survival for more patients.This review provides an insight into the physiological background for this technique and summarizes technical and surgical considerations,experiences from the past,patient outcomes,existing disputes and the future prospects.Overall,the procedure is complex and risky,with a small number of cases worldwide.Although many patients have achieved good outcomes,it is still insufficient to assess long-term on-cology outcomes.This method is still in the exploratory stage and limited to prospective clinical studies.

ABSTRACT

The detection rate of gallbladder adenomyomatosis has gradually increased, but the accuracy of preoperative diagnosis is low. Most doctors tend to expand the operation indications because they are worried about the carcinogenesis. But there are still great controversies on the key issues such as whether it is cancerous, operation indications and how to follow up for non-surgical patients. This article will review these key issues.

ABSTRACT

Objective:To investigate the clinical and imaging features of population receiving opportunistic screening for lung cancer and in convalescent stage of COVID-19.Methods:Cross-sectional study and analysis was performed on the patients who underwent chest low-dose CT examination for cancer prevention in Cancer Hospital of Chinese Academy of Medical Sciences from December 28, 2022 to January 19, 2023. All the patients completed the COVID-19 questionnaire. A total of 334 questionnaires were sent out, all of which were recovered, and 321 valid questionnaires were collected, among them, 293 questionnaires were included in the analysis. Statistical analysis was conducted according to the questionnaire information, clinical symptoms and chest CT imaging results. The potential influencing factors of COVID-19 infection were explored, and the imaging characteristics of COVID-19 infection and early stage of lung cancer were compared.Results:A total of 293 patients underwent lung cancer screening during the convalescent stage of COVID-19 infection. A total of 231 (78.8%) cases had cough and 228 (77.8%) cases had fever. 214 (73.0%) cases still had clinical symptoms within 2 weeks after nucleic acid or antigen test showing negative, especially for cough in 171 (58.4%) cases, fatigue in 79 (25.3%) cases and sputum in 73 (24.9%) cases. There were 54 (18.4%) cases with positive chest CT changes. The main imaging findings showed that there were 46 cases with new patchy shadows, 25 cases with linear opacities, 10 cases with ground-glass opacities, 10 cases with nodular like shadows and 2 cases with consolidation, and most lesions were in the subpleural area of both lungs. Univariate analysis showed that positive CT findings were correlated with the time from positive detection of COVID-19 to screening ( P=0.026), age ( P<0.001) and underlying diseases ( P=0.006). Multivariate analysis showed that age≥65 years old ( OR=6.425, 95% CI: 2.688-15.358; P<0.001) and underlying diseases ( OR=2.292, 95% CI: 1.120-4.691; P=0.023) were risk factors for pulmonary imaging changes of COVID-19 infection. For lung cancer opportunistic screening, 36 (12.3%) cases showed ground-glass opacities in bilateral or unilateral lung lobes, among which 4 cases were suspected to be atypical adenomatous hyperplasia and 2 cases s were suspected to be early stage of lung cancer. Conclusions:Abnormal clinical symptoms and chest CT findings are still observed in the patients during the convalescent stage of COVID-19 infection. Age≥65 years, underlying diseases were the high-risk factors for the changes in chest CT imaging after COVID-19 infection. Attention should be paid to the differential diagnosis of chest CT findings between changes in the convalescent stage of COVID-19 and early stage of lung cancer.

ABSTRACT

Objective:To detect the levels of γ-glutamyl transferase (GGT) in the amniotic fluid of normal pregnancies at 19-23 +6 gestational weeks and to analyze the changes in GGT level with gestational age. Methods:This study retrospectively collected the amniotic fluid supernatant from 383 singleton pregnant women (102, 103, 82, 68 and 28 cases at 19-19 +6, 20-20 +6, 21-21 +6, 22-22 +6, 23-23 +6 weeks of gestation, respectively) who underwent amniocentesis for prenatal diagnosis but had normal genetic diagnosis results in Cheeloo Hospital of Shandong University from January 2021 to September 2022. The levels of GGT in the amniotic fluid supernatant were tested and the statistical parameters including xˉ± s, min-max, median ( M), P1, P2.5, P5, P95, P97.5 and P99 values of GGT levels at each gestational week were calculated. GGT were non-normal data and converted into natural logarithms (lnGGT), and a least square linear regression equation was established to analyze the relationship between lnGGT and gestational week. Results:At 19-19 +6, 20-20 +6, 21-21 +6, 22-22 +6, and 23-23 +6 gestational weeks, the xˉ± s of amniotic fluid GGT were (385.8±235.7), (331.8±219.4), (253.7±197.9), (226.7±166.4), and (155.3±96.8) U/L, and the weekly declines were 14.0%, 23.5%, 10.6%, and 31.5%, respectively; the M values were 311.0, 288.0, 199.0, 160.5, and 105.5 U/L, and the weekly declines were 7.4%, 30.9%, 19.3%, and 34.3%, respectively; the P1- P99 were 67.1-1 404.5, 63.2-1 189.1, 36.0-849.8, 44.0-787.3, and 32.0-375.6 U/L, respectively. lnGGT was negatively correlated with gestational age ( R 2=0.148, P<0.001). Conclusions:In normal pregnancies at 19-23 +6 gestational weeks, GGT levels in amniotic fluid decrease with gestational age. Therefore, gestational age should be considered when establishing the reference value for amniotic fluid GGT in normal pregnancies.

ABSTRACT

Objective:To discuss the application effect of digital classroom based on identifying sectional structure in the experimental teaching of sectional anatomy.Methods:A total of 180 students majoring in imaging diagnosis from six classes of Batch 2018 in Mudanjiang Medical University were randomly selected as the research objects and divided into the experimental group and the control group. Three classes (90 people) in the experimental group implemented the digital classroom teaching of learning platform + virtual digital person, while another three classes (90 people) in the control group adopted traditional teaching. After the course, the effect was evaluated according to the results of the questionnaire and the final exam results. SPSS 18.0 software was used for t-test and Chi-square test. Results:The questionnaire showed that the students in the experimental groups were superior to those in the control group in self-study ability, independent thinking ability, analytical and problem-solving ability, learning efficiency, learning interest and sectional thinking cultivation, and the difference was statistically significant ( P<0.05). The test scores showed that the theoretical scores [(56.08±1.65) vs. (45.19±1.74)], experimental scores [(37.13±3.24) vs. (30.16±2.04)] and total scores [(93.21±3.18) vs. (75.35±1.79)] in the experimental group were higher than those in control group, and the differences were statistically significant ( P<0.05). Conclusion:The digital classroom based on identifying sectional structure is a feasible teaching mode, which improves the students' ability to analyze and solve problems, increases their interest in sectional anatomy, and improves the teaching effect.
