ABSTRACT
Objective:To analyze the predictive value of six hormonal changes in pregnant women with scarred uterus for the occurrence of oligohydramnios in their second pregnancy.Methods:A retrospective study was conducted to select the clinical data of 54 pregnant women with hypohydramnios in scarred uterus who were admitted to the First People’s Hospital of Suzhou from May. 2021 to Mar. 2023. They were included in the oligohydramnios group, and another 54 patients with normal amniotic fluid in scar uterus re-pregnancy during the same period were selected and included in the normal amniotic fluid group. Both groups of postpartum women underwent six hormone tests, including follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E 2), progesterone (P), testosterone (T), and prolactin (PRL). Two sets of baseline data were collected and binary logistic analysis was used to investigate the relationship between six hormones and oligohydramnios in women with scarred uterus during re-pregnancy. Receiver operating characteristic curve (ROC) was adopted to evaluate the six hormonal factors in predicting oligohydramnios in pregnant women with scar uterus during re pregnancy. The restricted cubic spline method combining spline function and logistic regression were used to analyze the dose-response relationship between six hormones and oligohydramnios in scar pregnant women during re-pregnancy. Results:The proportion of multiple pregnant women in the oligoamnios group [20.37% (11/54) ] was higher than that in the normal amniotic fluid group [5.56% (3/54) ] ( P < 0.05). The levels of FSH, E 2, P and PRL in oligohydramnios group were lower than those in normal amniotic fluid group [ (8.11±1.83) IU/L, (125.61±61.43) p /L, (16.33±3.15) mmol /L, (315.15±87.63) mIU/L],[ (9.87±2.05) IU/L, (148.52±50.57) pg/L, (20.14±4.07) mmol/L, (366.18±99.36) mIU/L] ( P<0.05) ; The levels of LH and T in oligohydramnios group [ (18.65±7.16) IU/L, (1.75±0.19) mmol/L] were compared with those in normal amniotic fluid group [ (20.67±8.53) IU/L, (1.73±0.11) mmol/L] and there was no significant difference between the two groups ( P<0.05). The results of binary logistic regression analysis showed that multiple pregnancy ( OR=11.507, 95% CI: 2.174-60.902, P=0.004) was a risk factor for recurrent oligohydramnios in women with scarred uterus. The high expression of FSH ( OR=0. 620, 95% CI: 0.224-0.845, P=0.001), E 2 ( OR=0.988, 95% CI: 0.978-0.998, P=0.021), and P ( OR=0.750, 95% CI: 0.645-0.873, P<0.001) was a protective factor for oligohydramnios in pregnant women with scar uterus during re-pregnancy. The ROC curve was plotted, and the results showed that AUC of FSH, P, and combined detection for predicting oligohydramnios in pregnant women with scarred uterus during re-pregnancy were 0.754, 0.768, and 0.870, respectively. The correlation between serum levels of FSH, E 2, and P and the occurrence of oligohydramnios in pregnant women with scarred uterus during re-pregnancy showed a linear dose-response relationship ( P<0.05). The levels of serum FSH, E 2, and P were negatively correlated with the occurrence of oligohydramnios in pregnant women with scar uterus. Especially when FSH<9.255 IU/L, E 2<158.465 pg/L, P<19.000 mmol/L, the occurrence of oligohydramnios in pregnant women with scar uterus increased with the decrease of FSH, E 2, and P levels. Conclusion:The six hormonal changes in pregnant women with scar uterus are closely related to the occurrence of oligohydramnios during re-pregnancy, and can effectively predict the risk of oligohydramnios during re-pregnancy.

ObjectiveTo study the correlation between the content of active ingredients of Aurantii Fructus in different main production areas and soil factors, so as to provide a theoretical basis for implementing ecological regulation of soil, improving the quality of Aurantii Fructus, and revealing the origin of genuine medicinal materials. MethodThe content of naringin, neohesperidin, total flavonoids, volatile oil, total nitrogen, total phosphorus, total potassium, and 17 soil factor-related indicators in 25 batches of Aurantii Fructus from different production areas were determined. The main soil factors affecting the content of active ingredients of Aurantii Fructus were analyzed by Pearson correlation analysis, principal component analysis, and grey correlation analysis. ResultThe pH value of the soil is between 4.83 and 8.21, and the soil is weakly acidic and neutral in general. Soil fertility exceeds the average. Pearson correlation analysis shows that the soil factors most related to the four active ingredients of Aurantii Fructus are total phosphorus, available copper, available zinc, exchangeable magnesium, available sulfur, available phosphorus, and available molybdenum. Principal component analysis shows that total nitrogen, alkali-hydrolyzable nitrogen, organic matter, available phosphorus, and available zinc are the main characteristic factors in soil. Grey correlation analysis shows that the main soil factors affecting the active ingredients of Aurantii Fructus are total phosphorus, total nitrogen, available zinc, available copper, exchangeable magnesium, and pH. ConclusionIn the cultivation of Aurantii Fructus, the medicinal material quality of Aurantii Fructus could be improved by adjusting the level of beneficial factors in the soil and improving the soil texture.
ABSTRACT
Objective:To analyze the clinical characteristics, diagnosis and treatments of patients with POEMS syndrome initially diagnosed as pulmonary hypertension (PH).Methods:Clinical data of 7 patients who were initially diagnosed as PH and finally diagnosed as POEMS syndrome in Shanghai Pulmonary Hospital from May 2013 to November 2021 were retrospectively reviewed. Clinical manifestations, laboratory tests, echocardiography, hemodynamic findings, treatment and prognosis of patients were analyzed.Results:Seven patients, including 4 males and 3 female, aged (55±9) (44-62) years were presented with elevated pulmonary artery pressure by echocardiography at admission. Chest tightness and shortness of breath (7/7), fatigue (6/7) and lower limb edema (4/7) were the most common symptoms in the first-episode. Meanwhile, patients also presented symptoms associated with POEMS syndrome, including multiple peripheral neuropathy (7/7), multiserosal cavity effusion (6/7), organomegaly (5/7), skin changes (5/7), and endocrine lesions (4/7). Serum levels of vascular endothelial growth factor (VEGF) were significantly increased in all patients. The pulmonary arterial systolic blood pressure was (66±21)mmHg (1 mmHg=0.133 kPa) estimated by echocardiography. Six patients underwent right heart catheterization and significantly increased mean pulmonary artery pressure((35±9) mmHg) was confirmed; and their pulmonary vascular resistance was (4.00±2.10) Wood U. All patients received corresponding treatment for POEMS syndrome. The excise tolerance was improved in 5 patients after successful treatment with stable or reversed WHO functional class. One patient received hemodialysis treatment for uncontrolled POEMS. One patient died during follow-up. The echocardiography was followed up in 4 patients, and 2 of whom had a complete reversal of PH, 1 had a partial reversal, and 1 had not yet reversed.Conclusions:In patients with PH who have multisystem manifestations, such as multiple peripheral neuropathy, multiserosal cavity effusion, organomegaly and skin changes, POEMS syndrome should be considered, and proper and active treatment of POEMS may reverse PH and improve the prognosis of patients.
ABSTRACT
Objective:To design a lung function prediction method that combines transfer learning and multimodal feature fusion, aiming to improve the accuracy of lung function prediction in patients with idiopathic pulmonary fibrosis (IPF).Methods:CT images and clinical text data were reprocessed, and an adaptive module was designed to find the most suitable lung function attenuation function for IPF patients. The feature extraction module was utilized to comprehensively extract features. The feature extraction module comprises three sub-modules, including CT feature extraction, clinical text feature extraction, and lung function feature extraction. A multimodal feature prediction network was used to comprehensively evaluate the attenuation of lung function. The pre-trained model was fine-tuned to improve the predictive performance of the model.Results:Based on the OSIC pulmonary fibrosis progression competition dataset, it is found through the adaptive module that the linear attenuation hypothesis is more in line with the trend of pulmonary function decline in patients. Different modal data prediction experiments show that the model incorporating clinical text features has better predictive ability than the model using only CT images. The model combining CT images, clinical text features, and lung function features have optimal predictive results. The lung function prediction method combining transfer learning and multimodal feature fusion has modified version of the Laplace log likelihood (LLLm) of ?6.706 5, root mean squared error (RMSE) of 184.5, and mean absolute error (MAE) of 146.2, which outperforms other methods in terms of performance. The pre-trained model has higher prediction accuracy compared to the zero base training model.Conclusions:The lung function prediction method designed by combining transfer learning and multimodal feature fusion can effectively predict the lung function status of IPF patients at different weeks, providing important support for patient health management and disease diagnosis.
ABSTRACT
@#Objective To analyze the echocardiographic characteristics of above grade 3+ mitral regurgitation (MR) patients by 3D transesophageal echocardiography (3D-TEE) in transcatheter edge-to-edge repair (TEER) and compare the intervention rate of TEER treatment in patients with different risk stratification. Methods We retrospectively analyzed the clinical data of 91 patients with above grade 3+ MR in Anzhen Hospital between June 2021 and April 2022. There were 45 males and 46 females aged 66.5±15.9 years. According to pathogenesis, the patients were divided into different anatomical groups and risk stratification groups. There were 34 patients in a simple degenerative group (simple DMR group), 28 patietns in a complex disease group (Complex group), 14 patients in a simple ventricular functional reflux group (simple VFMR group), 9 patients in a simple atrial functional reflux group (simple AFMR group), and 6 patients in a mixed functional reflux group (mixed FMR group). All patients were examined with a unified standard of transthoracic echocardiography (TTE) and 3D-TEE to compare the characteristic three-dimensional structural changes of the mitral valve in each group. According to the three partition strategy of preoperative anatomical evaluation of TEER, the risk stratification was conducted for the enrolled patients, which was divided into three regions from light to heavy: green area, yellow area, and red area. TEER treatment intervention rate of patients with different risk stratification was calculated. Results Ant leaf angle and post leaf angle were negative in the simple DMR and Complex groups, and non-planar angle, prolapse height and prolapse volume were higher than those of the other groups (P=0.000). Ant leaf angle and post leaf angle were positive in the VFMR group and the mixed FMR group. Anterior and posterior (AP) diameter of valve ring (P=0.036), tenting height and tenting volume were higher than those of other groups (P=0.000). AP diameter, tenting height and tenting volume were changed mildly in patients with simple AFMR. MR patients in red and yellow zone achieved a 28.1% TEER intervention rate. Conclusion Standardized TTE and TEE examinations are crucial for the qualitative and quantitative diagnosis of MR in the echo core-lab. 3D-TEE mitral valve parameter can help determine the exact pathogenesis of MR and to improve the interventional rate of challenging MR patients.
ABSTRACT
Acute kidney injury (AKI) is an important factor for the occurrence and development of CKD. The protective effect of dihydroartemisinin on AKI and and reported mechanism have not been reported. In this study, we used two animal models including ischemia-reperfusion and UUO, as well as a high-glucose-stimulated HK-2 cell model, to evaluate the protective effect of dihydroartemisinin on premature senescence of renal tubular epithelial cells in vitro and in vivo. We demonstrated that dihydroartemisinin improved renal aging and renal injury by activating autophagy. In addition, we found that co-treatment with chloroquine, an autophagy inhibitor, abolished the anti-renal aging effect of dihydroartemisinin in vitro. These findings suggested that activation of autophagy/elimination of senescent cell might be a useful strategy to prevent AKI/UUO induced renal tubular senescence and fibrosis.

@#Aortic stenosis (AS) is the most common primary valve lesion requiring surgery or transcatheter intervention in modern era. Its prevalence is rising rapidly as a consequence of the aging population. Transcatheter aortic valve replacement (TAVR) as a therapy option for older high-risk symptomatic severe AS patients has emerged and is currently extending its indications towards surgery intermediate- and low-risk subjects. Considering the common characteristics of frailty and high comorbidity among AS patients, cardiac rehabilitation (CR) has been proven to improve not only survival but also quality of life in previous reports. CR as a classⅠ recommendation in guidelines for the prevention and treatment of cardiovascular disease has been widely used in clinical practice. The purpose of this article is to sort out the current CR programs for TAVR patients in global medical management, and explore the CR optimization program fit for China medical model in post COVID-19 pandemic era.

ABSTRACT
BACKGROUND: Vernix caseosa (VC), which is known as a unique human substance, is a biofilm that covers the skin of most human newborns. VC has many biological functions including anti-infective, skin cleansing and skin barrier repair. OBJECTIVE: In the study, we purpose to investigate the novel effect of lipids extracted from VC on the regulation of filaggrin (FLG) expression and anti-inflammation in normal human epidermal keratinocyte (NHEK) cells. METHODS: The lipids were extracted by chloroform/methanol (Folch method) and the major properties of fatty acid methyl esters were determined with gas chromatography-mass spectrometer. The relative viability of NHEK cells was evaluated by Cell Counting Kit 8 assay. The related expression of skin barrier protein was accessed with real-time quantitative polymerase chain reaction, Western blot and Immunofluorescence in NHEK cells with or without poly (I:C). Meanwhile, the changes of thymic stromal lymphopoietin (TSLP) and tumor necrosis factor alpha (TNF-α) are analyzed by enzyme-linked immunosorbent assay. RESULTS: VC lipids mostly contained saturated and branched chains fatty acids. The expression of mRNA and protein of FLG were significantly increased after the supplement with lipid in NHEK cells. Meanwhile, lipids reversed the inhibition of poly (I:C) on FLG. Moreover, lipids suppressed the over secretion of TSLP and TNF-α induced by poly (I:C). CONCLUSION: These results indicate that lipids extracted from VC has positive effects on the expression of FLG and anti-inflammation, suggesting that lipids of VC may be used for a reference for novel therapeutic method in reducing and remedying skin disease like atopic disease.

Zinc levels are high in pancreatic β-cells, and zinc is involved in the synthesis, processing and secretion of insulin in these cells. However, precisely how cellular zinc homeostasis is regulated in pancreatic β-cells is poorly understood. By screening the expression of 14 Slc39a metal importer family member genes, we found that the zinc transporter Slc39a5 is significantly down-regulated in pancreatic β-cells in diabetic db/db mice, obese ob/ob mice and high-fat diet-fed mice. Moreover, β-cell-specific Slc39a5 knockout mice have impaired insulin secretion. In addition, Slc39a5-deficient pancreatic islets have reduced glucose tolerance accompanied by reduced expression of Pgc-1α and its downstream target gene Glut2. The down-regulation of Glut2 in Slc39a5-deficient islets was rescued using agonists of Sirt1, Pgc-1α and Ppar-γ. At the mechanistic level, we found that Slc39a5-mediated zinc influx induces Glut2 expression via Sirt1-mediated Pgc-1α activation. These findings suggest that Slc39a5 may serve as a possible therapeutic target for diabetes-related conditions.

Post procedure, there was no displacement of the occluder and heart valve movement was not affected,and there was no new hemolysis or hemolysis worsening.@*Conclusion@#Percutaneous closure of PVL in patients after heart valve replacement surgery with AVP Ⅲ is feasible, and associated with favorable short-and mid-term clinical outcomes.
ABSTRACT
Objective To investigate the clinical features, diagnosis, treatment and outcome of patients with Takayasu arteritis associated pulmonary hypertension (TA-PH). Methods Patients diagnosed as TA-PH in Shanghai Pulmonary hospital from 2008 to 2017 were retrospectively reviewed and followed up. Baseline characteristics including hemodynamics were collected. Data were summarized as mean ± standard deviation or frequency (%). Survival analyses were performed using the Kaplan-Meier method. Results Thirteen TA-PH patients (10 female, aged 39±11 years old) were included. The duration from symptoms onset to diagnosis was 2 months to 50 years, and ten patients were diagnosed TA and PH at the same time. Shortness of breath was the most common clinical manifestation (12 cases), followed by chest pain and tightness (8 cases) and palpitation (6 cases). All patients had a moderated WHO functional class and 8 patients were in active phase. Vessel wall thickening, lumen narrowing, occlusion and/or dilation were found in CT pulmonary angiography and angiography. Mean pulmonary arterial pressure (48.0±14.0) mmHg and pulmonary vascular resistant (7.59±4.21) Wood U were increased. All patients received PH-specific therapies, and patients at active status took glucocorticoid. Stentimplantation in pulmonary artery was performed in 4 patients. Three patients died during the follow-up. Conclusions Patients with TA are at risk of PH, and PH can be the first manifestation of TA, which suggest that PH should be screened regularly in patients with TA and shortness of breath. The prognosis of TA-PH is poor. PH-specific therapies and vascular reconstruction therapy may be effective, but need further investigation.
ABSTRACT
Objective@#To investigate the feasibility and efficacy of transcatheter closure of anastomotic leakage after aortic surgery using Amplatzer Vascular Plug Ⅲ (AVP Ⅲ).@*Methods@#A retrospective analysis was performed in 5 patients with anastomotic leakage after aortic surgery, who underwent transcatheter closure in our hospital from January to June 2017 using AVP Ⅲ. Surgeries were performed in 3 cases of Standford type A dissection, 1 case of ascending aortic aneurysm and 1 case of persistent truncus.There were 3 males,and age was (43.8±13.1) years old. Anastomotic leakages located at the ascending aorta in 4 patients, and the other one located between the aortic arch and the stent-graft.Three of them had aorta-right atrium fistula and patients suffered from progressive heart failure.

ABSTRACT
Objective To investigate the influence of the hematoma involving the aortic arch in endovascular aortic repair of complicated type B intramural aortic hematoma. Methods A total of 69 patients[58men; mean age(58.1±8.9)years; range 38-77]underwent endovascular repair between February 2011 and June 2015 were retrospectively reviewed. Patients with hematoma involving about the left subclavian artery level were categorized as group A(n=28) and patients without hematoma involvement to the aortic arch were categorized as group B (n=41). Results All the patients were treated with coverd aortic stents. The success rate was 97.1% with complete isolation of lesion in 67 patients. The average follow-up period was(19.6±14.1)months. During perioperative period, no procedure related deaths was recorded. Perioperative complications include paraplegia in 1case(1.4%) in group B and stent graft-induced new entry in 2 cases(2.9%) in group A. During the follow-up period 1 case in group A within 1 month and another 1 case in group B within 1 year developed new entries at proximal end of stents. 1 case (1.4%) in group B had asymptomatic type Ⅰ endoleak 2 years after TEVAR. Conclusions Type B aortic intramural hematoma with arch involvement is not a risk factor of stent-induced new entry in perioperative period after endovascular treatment and further studies are needed. Strict control of blood pressure is essential for the prevention of stent-related complications.

The average operative time was significantly longer in transverse group as compared to ascending group and sigmoid group [(192.1±58.7) min vs. (172.2±54.7) min and (169.1±53.6) min]( P<0.05), while the blood loss [(89.7±63.6) ml, (86.3±66.3) ml, (82.6±61.5) ml], conversion rate [3.3%(2/61), 2.6%(4/155), 2.2%(5/230)], number of harvested lymph node (13.0±4.7, 14.4±6.5, 13.4±5.6), time to flatus [(2.7±1.1) d, (2.6±1.1) d, (2.5±1.0) d], time to liquid diet [(3.0±1.7) d, (2.8±1.5) d, (2.7±1.4) d], incidence of postoperative complication(6.6%, 9.0%, 11.7%), and hospital stay [(11.6±5.8) d, (10.7±5.8) d, (10.6±5.7) d] among 3 groups were not significantly different (all P>0.05). A total of 436 patients received postoperative follow-up of median 36 (5 to 67) months. The overall 5-year survival rate was 73.1%, 73.7% and 74.8%, and the 5-year disease-free survival rate was 71.5%, 71.1% and 72.7% in transverse, ascending and sigmoid colon cancer groups respectively, whose differences were not significant among 3 groups (all P>0.05).</p><p><b>CONCLUSION</b>Laparoscopic complete mesocolic excision for transverse colon cancer is safe and feasible with slightly longer operation time, and has quite good long-term oncologic efficacy.</p>

Objective:To explore the time interval of using electric toothbrush after the adhesion of zinc polycarboxylate cement (ZPC) and PanaviaTM F(PF) respectively.Methods:The facial surfaces of 60 premolars were exposed and embedded in self-curing resin with custom made cylinder-shaped molds.Then the facial surfaces were cut with a diamond saw and polished with waterproof polishing papers to create standardized dentin surfaces.30 co-cr ally test-pieces and 30 zirconia ceramic test-pieces (4.0 mm in diameter and 2.0 mm in height) were adhered on 30 dentin surfaces respectively with ZPC and PF.The samples of each kind were divided into 5 groups (n =6) and brushed with an electronic toothbrush for 30 seconds immedietly (group 1),12 h (group 2),24 h (group 3)and 48 h(group 4) after adhesion,respectively.The samples in group 5 without brush were the controls.Shear bond strength of the samples was measured and the fracture patterns were observed under steriomicroscope.Results:In the ZPC adhered samples the bond strength of group 1,2,3 was lower than that of group 4 and 5 (P < 0.05),group 4 vs group 5,P > 0.05.In the PF adhered simples the bond strenth of group 1 and 2 was lower than that of group 3,4 and 5 (P < 0.05),group 3 or 4 vs group 5,P > 0.05.The fracture patterns were mostly cement cohesive failure.Conclusion:The time intervals of using electric toothbrush after the adhesion of ZPC and PF are 48 h and 24 h respectively
