Objective:To investigate the effect of laparoscopic splenectomy and azygoportal disconnection (LSD) on liver synthesis and development of liver cirrhosis.Methods:This is a prospective case series study.The clinical data of liver cirrhotic patients with portal hypertension who received LSD at the Department of Hepatobiliary Surgery of Northern Jiangsu People′s Hospital Affiliated to Yangzhou University from September 2014 to January 2016 were included. This study analyzed the diameter of the portal vein, the velocity of portal blood flow, the routine blood parameters, the liver function, the synthetic proteins of liver (antithrombin Ⅲ (AT-Ⅲ), protein S, protein C), and the serum content of liver fibrotic markers(collagen type Ⅳ, procollagen type Ⅲ, laminin, hyaluronidase). Repeated measures ANOVA was used for comparison between multiple groups, and least significance difference was used for post-hoc multiple comparison.Results:A total of 106 patients were included in the study, including 70 males and 36 females, aged (51.8±9.8) years(range: 28 to 75 years).Compared with the preoperative results, the diameter of portal vein and the velocity of portal vein decreased after surgery ( F=14.03, 12.15, respectively, both P<0.01). Compared with the preoperative results, the total bilirubin, albumin, prothrombin time, international normalized ratio, Child-Pugh score and classification were improved ( F=17.96, 56.01, 66.63, 35.83, 33.49, and 27.50, respectively, all P<0.01), and the AT-Ⅲ, protein S, protein C,collagen type Ⅳ, procollagen type Ⅲ, laminin and hyaluronidase levels were also improved ( F=47.87, 36.26, 18.02, 2.79, 14.58, 44.35, and 14.38, respectively, all P<0.01). Compared with the preoperative period, the diameter of portal vein was reduced from the first week to the 24 th month after surgery ( t=5.45 to 9.39, all P<0.01). Compared with the preoperative period, the velocity of portal vein blood from the first week after surgery to the 24 th month after surgery was decreased ( t=4.02 to 8.43, all P<0.01). Compared with the preoperative period, routine blood parameters (white blood count, hemoglobin, platelet count), liver function (total bilirubin, albumin, prothrombin time, international normalized ratio, Child-Pugh score), liver synthetic protein (AT-Ⅲ, protein S, protein C) and liver fibrotic markers (collagen type Ⅳ, procollagen type Ⅲ, laminin, hyaluronidase) were improved to varying degrees at the 24th month after surgery ( t=-20.46 to 11.93, all P<0.01). Conclusion:Preliminary findings show that LSD can reduce portal vein pressure, restore blood cell number, and improve liver synthesis function and the degree of liver fibrosis in patients with portal hypertension in liver cirrhosis.

OBJECTIVE To evaluate the comprehensive value of novel oral anticoagulant drugs （NOACs） after major orthopedic surgery. METHODS The evaluation evidence was collected through literature research； evidence and value：impact on decision-making （EVIDEM） framework was introduced to integrate the evaluation process； the multi-criteria decision analysis （MCDA） method was used to construct a multi-dimensional evaluation system； the weights assigned to each evaluation criterion were determined by the combination of Delphi method and analytic hierarchy process， and the rivaroxaban， dabigatran and apixaban were comprehensively evaluated. RESULTS The clinical comprehensive evaluation system of NOACs after major orthopedic surgery was successfully established， and the final clinical comprehensive evaluation weights of NOACs （rivaroxaban， dabigatran， apixaban） after major orthopedic surgery were calculated， with scores of 0.399 7 for rivaroxaban， 0.244 4 for apixaban， and 0.355 9 for dabigatran， indicating that rivaroxaban demonstrated the highest overall clinical value. Among them， rivaroxaban had the highest weight score in the evaluation of pharmaceutical characteristics， cost-effectiveness and other attributes in a single dimension. In terms of efficacy and safety evaluation， apixaban had the highest weighting score. CONCLUSIONS Among NOACs， rivaroxaban is more suitable for routine anticoagulation management after major orthopedic surgery， especially in terms of pharmacological properties， cost-effectiveness and other attributes.

Objective: To analyze the associations among body mass index (BMI), learning screen/gaming screen exposure and executive function in preschool children in Anhui Province, so as to provide a basis for promoting the development of executive function in preschool children. Methods: In June 2022, a stratified cluster sampling and convenience sampling methods were used to survey 3 534 mothers of preschool children in Wuhu City, Luan City, and Fuyang City, Anhui Province. The Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P) was used to assess the preschool childrens executive function abnormalities. Binary Logistic regression was conducted to examine the relationships among BMI, learning screen/gaming screen exposure, and their combined effects on executive function abnormalities. Results: The detection rate of abnormal executive function in preschool children was 9.65%. Logistic regression analysis showed that after adjusting for the confounding factors such as pregnancyinduced hypertension, primary caregivers, family per capita monthly income and family structure, the risk of abnormal executive function of children in overweight/obesity group and high learning screen/gaming screen exposure group increased significantly (overweight/obesity:OR=1.78, 95%CI=1.31-2.42, learning screen exposure:OR=1.48, 95%CI=1.18-1.86, gaming screen exposure:OR=1.50, 95%CI=1.18-1.91,P<0.05). Compared with children with normal BMI and low learning screen/gaming screen screen exposure, those with both overweight/obesity and high learning screen/gaming screen exposure had a significantly greater risk of executive function abnormalities (OR=2.07, 95%CI=1.29-3.31; OR=2.42, 95%CI=1.59-3.68,P<0.05). Conclusions Overweight/obesity and high learning screen/gaming screen exposure are important risk factors for executive function abnormalities in preschool children. Therefore, actively guiding preschool children to develop healthy life habits to promote the normal development of their executive functions is essential.

AIM: To explore the effect of lncRNA SNHG6 on injury of human retinal microvascular endothelial cells(hRMECs)induced by high glucose and its possible mechanism.METHODS: The D-glucose-induced hRMECs were used to establish normal glucose(NG)and high glucose(HG)cell injured model. In the HG group, the hRMECs were cultured in DMEM medium at a concentration of 25 mmol/L D-glucose for 24 h, while in the NC group, they were cultured in DMEM medium at a concentration of 5.5 mmol/L D-glucose; according to experimental design, si-NC, si-SNHG6, si-SNHG6 and anti-miR-NC and si-SNHG6 and anti-miR-186-5p were transfected into hRMECs, and then incubated at a concentration of 25 mmol/L D-glucose for 24 h, with HG+si-NC group, HG+si-SNHG6 group, HG+si-SNHG6+anti-miR-NC group and HG+si-SNHG6+anti-miR-186-5p group marked, respectively. The quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the expression of lncRNA SNHG6 and miR-186-5p; dual-luciferase reporter assay was used to detect the targeting relationship; MTT assay and flow cytometry were used to detect the cell proliferation and apoptosis, respectively; enzyme linked immunosorbent assay(ELISA)was used to detect the levels of IL-1β, TNF-α, IL-8, IL-10; testing kits were used to detect activity of SOD and level of MDA; the Western blot was used to detect the protein expression of cleaved-caspase3, Bax and Bcl-2.RESULTS: The lncRNA SNHG6 expression increased in the HG group, while miR-186-5p expression decreased(both P<0.05). There was target binding of lncRNA SNHG6 with miR-186-5p. After the transfection of si-SNHG6, cell inhibition rate, apoptosis rate, cleaved-caspase3, Bax protein levels, IL-1β, TNF-α, IL-8 contents, and MDA activity were decreased(P<0.05), while Bcl-2 protein, IL-10 contents, and SOD activity were increased(P<0.05). Co-transfection of si-SNHG6 and anti-miR-186-5p increased cell proliferation inhibition rate, apoptosis rate, cleaved-caspase3, Bax, IL-1β, TNF-α, IL-8, and MDA(P<0.05), but decreased Bcl-2, IL-10 and SOD(P<0.05).CONCLUSION: Interfering with lncRNA SNHG6 could inhibit cell apoptosis, inflammation and oxidative stress of high-glucose- induced hRMECs by elevating the expression of miR-186-5p.

Objective:To investigate the role of speckle-type POZ(pox virus and zinc finger protein) protein (SPOP) in enterovirus 71 (EV71) infection.Methods:Immunoprecipitation analysis was employed to examine the impact of SPOP on the ubiquitin level of EV71 non-structural protein 2A protease (2A pro), while the phosphorylation level of IFR3 protein was assessed through Western blot. Cells were either overexpressed or knockdown of SPOP, followed by infection with EV71. RT-qPCR was utilized to analyze the transcription level of IFN-β, and the transcription level and protein level of EV71 structural protein VP1 were determined using RT-qPCR and Western blot, respectively. Results:The inhibition of EV71 infection in RD cells was observed following transfection with HA-SPOP. Additionally, it was found that the ubiquitin level of EV71-2A pro increased in a gradient-dependent manner. Subsequent transfection with shSPOP plasmid for endogenous SPOP knockdown resulted in a dose-dependent decrease in the levels of melanoma differentiation-associated gene 5 (MDA5), mitochondrial antiviral signaling (MAVS), and p-IRF3. Conversely, transfection with HA-SPOP plasmid led to a dose-dependent increase in the levels of MDA5, MAVS, and p-IRF3. The expression of SPOP, whether high or low, had an impact on the expression of IFN-β in cells. Additionally, the levels of VP1 mRNA or protein were found to be inhibited or increased. Conclusions:SPOP plays a role in increasing the ubiquitination level of EV71-2A pro, which in turn promotes the phosphorylation level of IRF3 and secretion of IFN-β. This effect is achieved by inhibiting the cleavage of 2A pro against key molecules MAVS and MDA5 in the RLR signaling pathway, ultimately leading to the inhibition of EV71 replication.

Objective:To observe the clinical outcomes of continued pregnancy in pregnant women with cesarean scar pregnancy (CSP).Methods:A retrospective analysis was performed on the pregnancy outcomes of 55 pregnant women who were diagnosed with CSP at the Second Affiliated Hospital of Army Medical University during the first trimester of pregnancy from August 1st, 2018 to October 31st, 2021 and strongly requested to continue the pregnancy.Results:Of the 55 pregnant women, 15 terminated the pregnancy in the first trimester, 1 underwent hysterotomy at 23 weeks of gestation due to cervical dilation, and 39 (71%, 39/55) continued pregnancy to the third trimester achieving live births via cesarean section. The gestational age of the 39 pregnant women delivered by cesarean section was 35 +6 weeks (range: 28 +5-39 +2 weeks), of whom 7 cases at 28 +5-33 +6 weeks, 20 cases at 34-36 +6 weeks, and 12 cases at 37-39 +2 weeks. The results of pathological examination were normal placenta in 3 cases (8%, 3/39), placenta creta in 4 cases (10%, 4/39), placenta increta in 9 cases (23%, 9/39) and placenta percreta in 23 cases (59%, 23/39). Among the 36 pregnant women who were pathologically confirmed as placenta accreta spectrum disorders (PAS) after surgery, the last prenatal ultrasonography showed placenta previa in 27 cases (75%, 27/36) and not observed placenta previa in 9 cases. The median intraoperative blood loss, autologous blood transfusion, and allogeneic suspended red blood cell infusion of 39 pregnant women during cesarean section were 1 000 ml (300-3 500 ml), 300 ml (0-2 000 ml) and 400 ml (0-2 400 ml), respectively. The uterine preservation rate was 100% (39/39), and only 1 case received cystostomy due to intracystic hemorrhage. The birth weight of the newborn was 2 580 g (1 350-3 800 g), and 1 case of mild asphyxia. Conclusions:Pregnant women with CSP who continue pregnancy under close monitoring after adequate ultrasound evaluation and doctor-patient communication could achieve better maternal and infant outcomes, but pregnant women with CSP are highly likely to continue pregnancy and develop into PAS. Effective hemostasis means and multidisciplinary team cooperation are needed in perinatal period for ensuring maternal and fetal safety.

Objective:To analyze the early identification, clinical characteristics, diagnosis and treatment of gestational hypertension crisis combined with adrenal disease.Methods:The clinical data of 23 patients of HCP complicated with adrenal disease admitted from Jul. 2009 to Jul. 2019 were retrospectively studied. The clinical characteristics, imaging characteristics, treatment and clinical transfer were studied.Results:The occurrence of all the 23 cases were acute. Among them, 16 cases had eclampsia combined with Cushing’s syndrome, 4 cases were pregnancy combined with primary aldosteronism (PA) and extreme hypokalemia, and 3 cases had eclampsia combined with pheochromocytoma (PHEO) . After admission, the patients were given symptomatic support treatment for sedation, analgesia, blood pressure control, dehydration, cranial pressure reduction, electrolyte balance and spasmolysis, and patients with severe preeclampsia and preeclampsia terminated their pregnancy in time. After treatment, 3 patients gave live birth, 12 received postpartum surgical treatment and 10 received drug treatment. The clinical symptoms improved and imaging examination suggested the lesions in the brain narrowed and disappeared, except one patient had major cerebral hemorrhage and died of multiple organ failure.Conclusions:In case of HCP and severe hypokalemia, relevant examinations should be improved in combination with symptoms to comprehensively diagnose whether it is complicated with adrenal diseases. The treatment methods and process of HCP with adrenal diseases need to be optimized, so as to judge the timing of termination of pregnancy, and minimize the impact on mother and fetus.

Hepatocellular carcinoma （HCC） most often develops in patients with liver disease characterized by chronic non-resolving inflammation. The inflammatory response is mainly derived from innate immune cells， and tumor-associated macrophages （TAMs） play an important role in the development of tumors．It is usually chemotactic from mononuclear progenitor cells in the blood to tumor tissue， then is induced by the tumor microenvironment and further develops into TAMs. They play an important role in promoting tumor growth，angiogenesis and tumor invasion and inducing tumor tissues to form an environment without inhibition mechanisms. As the relationship between TAMs and malignant tumors becomes clearer， TAMs are beginning to be seen as therapeutic targets. The heterogeneity of TAM subtypes and their origin and dynamic phenotype during the initiation and progression of HCC has been partially unraveled. It further forms the base for developing therapeutic agents by decreasing the population of TAMs via blocking recruitment of bone marrow-derived monocytes and functionally reprograms TAMs to anti-tumoral behavior. This review focuses on the preclinical evolution and hitherto clinical trials for TAM-targeted therapy in HCC.
