Objective To investigate the effects of comprehensive nutrition management on glycolipid metabolism and pregnancy outcomes in patients with gestational diabetes mellitus(GDM).Methods A total of 121 pregnant women with GDM at 24-28 weeks gestation who were registered in the obstetrics department of 6 sub-central hospi-tals in China from May 2021 to July 2021 were included in this study and were randomly divided into intervention group(n=74)and control group(n=47).The intervention group received intensive comprehensive nutrition man-agement,including at least 6 outpatient interventions,individualized nutrition management and a half-day standard-ized outpatient education on gestational diabetes mellitus,continuous dynamic blood glucose monitoring and micro-blood glucose monitoring,and routine check of glycated albumin and urine every 4 weeks.Body weight,body com-position and diet and exercise implementation procedures and fetal development as well as complications were recor-ded.The control group received conventional nutritional guidance.The two groups were compared for difference in blood glucose related indicators at 37 weeks of gestation,weight gain before delivery,some lipid metabolism indica-tors,pregnancy outcomes,and oral glucose tolerance test(OGTT)at 42 days postpartum.Results Compared with the control group,the level of prenatal fasting blood glucose(P=0.006),intravenous plasma glucose(P=0.009)and blood ketone(P = 0.044)in the intervention group was significantly reduced.There was no significant difference in weight gain and weight attainment rate between the two groups.The 2-hour postpartum OGTTs of preg-nant women in the intervention group(P=0.006)were significantly lower than those in the control group,and the incidence of preeclampsia and postpartum blood loss were lower than those in the control group but no statistical difference was found.For newborns,the incidence of macrosomia(P=0.042)and planation(P=0.048)in the in-tervention group was slightly lower than that in the control group,and the results were statistically different.Other adverse pregnancy outcomes were not statistically different between the two groups.Conclusions Intensive compre-hensive nutrition management has a positive impact on the control of the blood glucose in pregnant women and im-proves the maternal and neonatal outcomes of women with GDM.

Stomach exuberance and spleen deficiency are common pathogenesis of many metabolic diseases. Through analyzing the pathogenesis of stomach exuberance and spleen deficiency， it is believed that its essence is stomach heat and spleen deficiency. Stomach heat includes gastrointestinal heat， spleen and stomach damp-heat， and spleen deficiency is divided into deficiency of spleen yin， deficiency of spleen qi ， and deficiency of spleen yang. It is suggested that the metabolic diseases of stomach-exuberance and spleen-deficiency syndrome can be divided into three categories，i.e. stomach-heat and spleen yin-deficiency， stomach-heat and spleen qi-deficiency， and stomach-heat and spleen yang-deficiency， and the main treatment methods are clearing and draining heat， nourishing yin and moistening intestine， clearing dampness and heat， strengthening spleen and qi， clearing dampness and heat， strengthening spleen and warming yang， respectively， with prescriptions as Maziren Pills （麻子仁丸）， Qinlian Pingwei Powder （芩连平胃散）， and Jiawei Lianli Decoction （加味连理汤） accordingly.

Objective:To observe the multi-modal fundus imaging features of subretinal drusenoid deposit (SDD) in age-related macular degeneration (AMD), and observe image features.Methods:A prospective clinical study. From December 2019 to December 2023, 65 patients (104 eyes) with a diagnosis of AMD-SDD by spectral domain optical coherence tomography (SD-OCT) examination in Shandong Eye Hospital were included. All eyes were examined by best corrected visual acuity (BCVA), traditional color fundus photography (CFP), ultra-wide-angle scanning laser fundus imaging (UWF), multicolor scanning laser fundus imaging (MC) and SD-OCT. The standard MC images were obtained by using Spectralis HRA+OCT for MC examination. The multi-mode image characteristics of SDD were analyzed retrospectively. Area under curve (AUC) was used to evaluate the sensitivity and specificity of CFP, MC and UWF in detecting SDD.Results:Among 65 patients with SDD, 29 cases of males (52 eyes) and 36 cases of females (52 eyes) was included. There were 26 patients with unilateral SDD and 39 patients with bilateral SDD. The average age was (71.74±10.97) years. The early, middle and late stages of AMD were 31 (29.8%, 31/104), 24 (23.1%, 24/104), 49 (47.1%, 49/104) eyes, respectively. The SDD detected by CFP, MC and UWF was 76 (73.1%, 76/104), 94 (90.4%, 94/104), 96 (92.3%, 96/104) eyes. CFP showed that the edge of SDD in the macular area was blurred. UWF showed that the dot and the ribbon SDD were light yellow pale discrete deposits and light yellow interlaced network deposits respectively. MC showed the dot SDD had a strong yellow-green circular reflection, while the edge of the ribbon SDD was surrounded by a weak reflection, and the boundary was clear. SD-OCT showed that SDD had strong reflection signal, which was located between the retinal pigment epithelium layer and the photoreceptor cell layer. The dot SDD could break through the ellipsoid zone and caused slight uplift or interruption of the external membrane, showing a cone-like strong reflection signal. While the ribbon SDD showed a continuous "hill-like" protrusion, which hardly broke through ellipsoid zone. The sensitivity and specificity of CFP, MC and UWF for SDD were 73.1%, 90.4%, 92.3% and 61.1%, 94.4% and 83.3%, respectively.Conclusions:MC and UWF show high sensitivity and specificity in diagnosing AMD-SDD, which is superior to CFP. SD-OCT can effectively reveal the location and morphoLogical characteristics of SDD under retina.

NK/T cell leukemia/lymphoma is a type of malignancy originating from T cells or natural killer cells with low incidence and poor clinical prognosis. There is still no effective treatment strategy. In recent years, targeted therapy has made great progress in the treatment of hematological malignancies, including monoclonal antibody and chimeric antigen receptor T cells (CAR-T), among which CD30, CD7, CD5, CD52, CCR4 and other target antigens are effective in the treatment of NK/T cell leukemia/lymphoma, but its widespread application still faces a great challenge. This article reviews the progress of immunotherapy for NK/T cell leukemia/lymphoma.

Objective:To compare the efficacy and safety of venetoclax (VEN) combined with azacitidine (AZA) versus CAG regimen combined with decitabine (DAC) in elderly patients with relapsed acute myeloid leukemia (AML).Methods:From January 2018 to August 2020, the clinical data of forty-five elderly patients with relapse AML at the First Affiliated Hospital of Soochow University were retrospectively analyzed, including 31 males and 14 females. The median age was 66 (60-80) years old. Eighteen patients were administrated with VEN and AZA, while the other 27 were in CAG with DAC. The complete remission (CR) rate, partial remission (PR) rate, total remission rate (ORR), adverse events and overall survival (OS) were compared between the two groups.Results:At the end of the treatment, the ORR in VEN with AZA group was 77.8% (14/18); including 11 CR and 3 PR. In CAG with DAC group, the ORR was 37.0% (10/27); including 8 CR and 2 PR ( P=0.007). Subgroup analysis suggested that VEN with AZA had a higher ORR in patients stratified as intermediate and poor-risk ( P=0.013) or with DNA methylation mutations ( P=0.007). Main adverse events in both groups were bone marrow suppression, infections, nausea and vomiting, anorexia and fatigue. Grade Ⅲ-Ⅳ cytopenia developed in lower incidence of VEN with AZA group, such as leukopenia (66.7% vs. 100%, P=0.002), anemia (50.0% vs. 92.6%, P=0.002), thrombocytopenia (72.2% vs. 96.3%, P=0.031) and neutropenia (61.1% vs. 92.6%, P=0.014). In addition, less grade Ⅲ-Ⅳ infections occurred in VEN with AZA group (66.7% vs. 33.3%, P=0.028), as well as grade Ⅲ-Ⅳ gastrointestinal events (40.7% vs. 11.1%, P=0.032), grade Ⅲ-Ⅳ fatigue (55.6% vs.11.1%, P=0.003) compared with CAG with DAC group. The 1-year OS in VEN with AZA group versus CAG with DAC group was 42.9% and 31.6% respectively ( P=0.150). Conclusion:VEN combined with AZA proves favorable efficacy and tolerablity in elderly patients with relapsed AML.

Objective:To observe the characteristics of macular telangiectasia (MacTel) in multi-color and multi-mode fundus images.Methods:An abservational case series study was conducted.Sixteen eyes of 12 patients diagnosed with MacTel by fluorescein fundus angiography (FFA) from January to November 2019 in Shandong Eye Hospital were analyzed.There were 8 cases (8 eyes) with MacTel type Ⅰ, among which 4 cases were male and 4 cases were female, with an average age of (62.3±12.5) years.The other 4 cases (8 eyes) had MacTel type Ⅱ, all of which were female, with an average age of (58.7±10.5) years.Best corrected visual acuity, slit lamp microscopy, color fundus photography, multicolor scanning laser imaging, FFA, optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) were carried out in all the patients.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Shandong Eye Institute (No.2019S003).Results:In color fundus images of MacTel type Ⅰ eyes, annular macular exudation with macular edema occurred in 6 eyes, macular edema without hard exudates in 1 eye, and hard macular exudates without macular edema in 1 eye.However, the transparency of retina in temporal fovea in MacTel type Ⅱ eyes decreased, showing a gray color.In multi-color fundus images of MacTel type Ⅰ eyes, punctate granular yellow macular exudation and yellow-green macular edema were observed, which were clearer than those in color fundus images.Punctate exudation was seen in both the blue and green reflectance images, which was clearest in green reflectance image, followed by blue reflectance image and then the infrared reflectance image.In OCT images of MacTel type Ⅰ eyes, cystoid edema of inner retina or uneven reflection signal of outer plexiform retina were observed.Loss of inner and outer retinal structures and cavities were observable in MacTel type Ⅱ eyes, and outer retinal atrophy appeared in 2 eyes.In OCTA images, the destruction of superficial and deep capillary plexus in macular area were observed in both MacTel typeⅠand type Ⅱ eyes, and the destruction of deep capillary plexus was more obvious.In addition, more obviously increased vascular space, decreased vessel density, and increased foveal avascular zone were found in MacTel type Ⅱ eyes.In early stage of FFA, delayed capillary filling near fovea was seen in MacTel typeⅠeyes, and dilated temporal vessels in fovea, some of which showed tumor-like dilation, and the limited tumor-like dilation was enhanced in the later stage.Different degrees of dilated parafoveal blood vessels in the early stage, and the capillary in the temporal side of the macula showing diffuse strong fluorescence in the late stage of FFA was observed in MacTel type Ⅱ eyes.Conclusions:Multi-color scanning laser imaging can be used to observe the morphological characteristics of MacTel, and the imaging features of different types of MacTel are significantly different.

Objective: To investigate the correlation between skin elasticity and setup error in optical surface image-guided radiotherapy. Methods: The skin elasticity (R7) data of the head, chest and abdomen were extracted and analyzed its correlation with age by systematic literature review. Fifty-four patients diagnosed with nasopharyngeal carcinoma, breast cancer and cervical cancer were recruited in this study. Firstly, the patients were positioned based on the room laser and markers. Subsequently, the patient position was verified by the Varian On-Board Imager, and then C-Rad Catalyst was adopted to obtain surface images in two states (mask or non-mask) as reference images. In the subsequent fraction treatment, after initial positioning, the local calibration was performed by Catalyst, and setup errors in three directions were recorded. Meanwhile, the patient setup was verified by CBCT twice a week. The Pearson correlation analysis was performed to analyze the correlation between setup error and age. Results: The skin elasticity was negatively correlated with aging (P<0.01). The correlation coefficient between random error and age in head-and-neck cancer were 0.645, 0.624 and 0.866 in the AP, SI and LR directions (all P<0.05) for male patients without mask, respectively. The system error was significantly correlated with age in the LR direction (P<0.05) for male patients, and in the AP direction (P<0.05) for female patients with head-and-neck cancer without mask. The setup error had a significant correlation with skin elasticity in male patients with head-and-neck cancer, and the sequence of absolute value of correlation coefficient was LR>SI>AP. Conclusion In optical surface-guided radiotherapy of head and neck cancer, skin elasticity may be a significant index for assessing the setup errors in male patients.

Objective To investigate the expression of plasma microRNA-214 in patients with acute myocardial infarction (AMI) and its correlation with left ventricular remodeling (LVR). Methods A total of 158 AMI patients and 85 controls were selected from Hebei province Zhuozhou City Hospital. According to the left ventricular remodeling after PCI operation, AMI patients were divided into LVR group (n=41) and non LVR group (n=105). Real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the plasma microRNA-214 levels, and the brain natriuretic peptide (BNP) and C-reactive protein (CRP) levels were detected by immunoassay. Pearson correlation analysis of plasma microRNA-214 levels and the correlation between CRP and BNP were analyzed in patients with LVR. The receiver operating characteristic (ROC) curve analysis of plasma microRNA-214, BNP and CRP were used to predict the efficacy of LVR in patients with AMI after PCI. Logistic regression model was used to analyze the relationship between the above indexes and LVR. Results Compared with the control group, left ventricular ejection fraction (LVEF) and left ventricular short axis shortening (FS) were significantly decreased in LVR group and non LVR group, and which were decreased more significantly in LVR group compared with those of non LVR group (P<0.05). The left ventricular end diastolic diameter (LVDD), left ventricular end diastolic volume (LVEDV) and left ventricular end systolic volume (LVESV) were significantly increased in LVR group and non LVR group, and which were increased more significantly in LVR group than those in non LVR group (P<0.05). The levels of plasma microRNA-214, BNP and CRP were significantly higher in LVR group than those in non LVR group and control group (P<0.05). Correlation analysis showed that microRNA-214, BNP and CRP were positively correlated in patients with LVR (r=0.684 and r=0.405, P<0.01). The area under ROC curve (AUC) and 95%CI predicted by plasma microRNA-214 and BNP were 0.824 (0.757-1.015) and 0.785 (0.721-0.864) in patients with AMI and LVR, which were higher than CRP [0.716 (0.645-0.837), P=0.0167]. The sensitivity and specificity of plasma microRNA-214 in predicting the occurrence of LVR were 72.6% and 86.2% in patients with AMI, respectively. Logistic regression model analysis showed that plasma microRNA-214 and BNP were risk factors of LVR. Conclusion High expression of plasma microRNA-214 is found in LVR patients, which is expected to be the biological indicator for predicting the occurrence of LVR after PCI in patients with AMI.
