Objective To investigate the relationship between the ratio of soluble hemoglobin scavenger receptor 163 protein(sCD163)/soluble tumor necrosis factor-like weak inducer of apoptosis(sTWEAK)in plasma and prognosis in patients with spontaneous acute cerebral hemorrhage(ACH).Methods From August 2020 to August 2022,90 patients with ACH admitted to the Department of Neurosurgery,Harison International Peace Hospital,Hengshui City were regarded as the research group.According to the Glasgow outcome scale,patients with ACH were separated into the poor prognosis group(n=38)and the good prognosis group(n=52).Another 45 healthy examinee who underwent physical examination were used as the control group.Enzyme linked immunosorbent assay(ELISA)was applied to detect plasma sCD163 and sTWEAK levels,and the sCD163/sTWEAK ratio was calculated.Pearson method was applied to analyze the correlation between plasma sCD163,sTWEAK levels,sCD163/sTWEAK ratio and clinical data.Logistic regression was applied to analyze influencing factors of poor prognosis in patients with ACH.Receiver operating characteristic(ROC)was applied to analyze the predictive value of sCD163/sTWEAK ratio for poor prognosis of patients with ACH.Results The plasma levels of sCD163,sTWEAK and sCD163/sTWEAK ratio were obviously higher in the research group than those in the control group(P＜0.05).The plasma levels of sCD163,sTWEAK and sCD163/sTWEAK ratio were obviously lower in the good prognosis group than those in the poor prognosis group(P＜0.05).Hematoma volume,National Institutes of Health Stroke Scale(NIHSS)scores,hypertension and subtentorial hemorrhage were lower in the good prognosis group than those in the poor prognosis group,and low density lipoprotein cholesterol(LDL-C)was higher in the good prognosis group than that in the poor prognosis group(P＜0.05).Correlation analysis showed that plasma sCD163,and sTWEAK levels and the sCD163/sTWEAK ratio were positively correlated with bleeding site,hematoma volume,NIHSS score,white blood cell count,platelet count and neutrophil/lymphocyte ratio(NLR)(P＜0.05).Results of Logistic regression analysis showed that sCD163,sTWEAK,sCD163/sTWEAK ratio,hematoma volume,bleeding site and NIHSS score were influencing factors for poor prognosis in patients with ACH(P＜0.05).Results of receiver operating characteristic showed that the AUC of sCD163/sTWEAK ratio in evaluating poor prognosis of patients with ACH was 0.850,and the sensitivity and specificity were 86.84%and 69.23%.Conclusion The sCD163/sTWEAK ratio has a high level in the plasma of patients with ACH,which is associated with poor prognosis and has important value in predicting the prognosis of patients with ACH.

Oral diseases concern almost every individual and are a serious health risk to the popula-tion.The restorative treatment of tooth and jaw defects is an important means to achieve oral function and support the appearance of the contour.Based on the principle of"learning from the nature",Deng Xu-liang's group of Peking University School and Hospital of Stomatology has proposed a new concept of"microstructural biomimetic design and tissue adaptation of tooth/jaw materials"to address the worldwide problems of difficulty in treating dentine hypersensitivity,poor prognosis of restoration of tooth defects,and vertical bone augmentation of alveolar bone after tooth loss.The group has broken through the bottle-neck of multi-stage biomimetic technology from the design of microscopic features to the enhancement of macroscopic effects,and invented key technologies such as crystalline/amorphous multi-level assembly,ion-transportation blocking,and multi-physical properties of the micro-environment reconstruction,etc.The group also pioneered the cationic-hydrogel desensitizer,digital stump and core integrated restora-tions,and developed new crown and bridge restorative materials,gradient functionalisation guided tissue regeneration membrane,and electrically responsive alveolar bone augmentation restorative membranes,etc.These products have established new clinical strategies for tooth/jaw defect repair and achieved inno-vative results.In conclusion,the research results of our group have strongly supported the theoretical im-provement of stomatology,developed the technical system of oral hard tissue restoration,innovated the clinical treatment strategy,and led the progress of the stomatology industry.

Objective To evaluate the molluscicidal effect of spraying 5% niclosamide ethanolamine salt granules with drones against of Oncomelania hupensis snails in snail habitats in marshland areas. Methods From September to October, 2022, marshlands were sampled from Dantu District, Zhenjiang City, Jiangsu Province as study areas, and assigned into four groups, of approximately 3 000 m² per group. In Group A, environmental cleaning was performed, followed by spraying 5% niclosamide ethanolamine salt granules with knapsack sprayers at a dose of 40 g/m², and in Group B, 5% niclosamide ethanolamine salt granules were sprayed with knapsack sprayers at a dose of 40 g/m² without environmental cleaning, while in Group C, environmental cleaning was conducted, followed by spraying 5% niclosamide ethanolamine salt granules with drones at a dose of 40 g/m², and in Group D, 5% niclosamide ethanolamine salt granules were sprayed with drones at a dose of 40 g/m² without environmental cleaning. Then, the study areas in each group were equally divided into six blocks, with Block 1 for baseline surveys and blocks 2 to 6 for snail surveys 1, 3, 5, 7, 14 days following chemical treatment. The mortality of snails and the reduction of the density of living snails were calculated. Results A total of 132 frames were surveyed during the period from September to October 2022, and the occurrence of frames with living snails and means density of living snails were 61.36% (81/132) and 1.58 snails/0.1 m², respectively. The overall mortality rates of snails were 43.02% (77/179), 38.69% (77/199), 47.78% (86/180) and 31.02% (58/187) 14 days following chemical treatment in groups A, B, C and D, respectively (χ² = 11.646, P < 0.05), and there were differences detected in the snail mortality between group A and D, and between groups C and D (both P_adjusted values < 0.05). The adjusted mortality rates of snails were 37.42%, 36.07%, 38.85% and 40.40% in groups A, B, C and D 14 days post-treatment, and the density of living snails decreased by 48.10%, 63.29%, 67.09% and 69.62% 14 days post-treatment relative to pre-treatment, respectively. Conclusions Chemical treatment with drones is feasible for O. hupensis snail control in marshland areas; however, the molluscicidal effect of spraying 5% niclosamide ethanolamine salt granules with drones is comparable to spraying chemicals manually in marshland areas regardless of environmental cleaning.

Objective To investigate the effects of pterostilbene on human colon cancer LoVo cells and study the regulatory mechanism of nuclear factor E2-related factor 2(Nrf2)in the process of pterostilbene acting on LoVo cells.Methods LoVo cells were treated with different concentrations(5,10,20,40,60,80,100 panol/L)of pterostilbene.Cell viability,migration,invasion,and apoptosis were examined by CCK-8,scratch,Tran-swell,and TUNEL assays,respectively.The mitochondrial membrane potential was measured by the mitochon-drial membrane potential assay kit with JC-1.The reactive oxygen species level was measured by 2',7'-dichlo-rofluorescein diacetate.The protein levels of Nrf2,phosphorylated Nrf2,heme oxygenase 1,and apoptotic pro-teins(Bcl2 and Bax)were determined by Western blotting.In addition,cell viability,Nrf2 expression,and ap-optosis rate were determined after co-application of the Nrf2-specific agonist sulforaphane.Results Compared with the control group,40,60,80,100 μmol/L pterostilbene reduced the viability of LoVo cells(P=0.014,P＜0.001,P＜0.001,P＜0.001).Pterostilbene at 5,10,20 μmol/L did not show effects on cell viability but inhibited cell migration(P=0.008,P＜0.001,P＜0.001)and invasion(all P＜0.001).Pterostilbene at 40,60,80 μmol/L increased apoptosis(P=0.014,P＜0.001,P＜0.001),promoted mitochondrial membrane potential depolarization(P=0.026,P＜0.001,P＜0.001)and reactive oxygen species accumula-tion(all P＜0.001),and down-regulated the expression of phosphorylated Nrf2(P=0.030,P＜0.001,P＜0.001),heme oxygenase 1(P=0.015,P＜0.001,P＜0.001),and Bc12(P=0.039,P＜0.001,P＜0.001)in LoVo cells.Pterostilbene at 60,80 μmol/L down-regulated Nrf2 expression(P=0.001,P＜0.001)and up-regulated Bax expression(both P＜0.001).The application of sulforaphane reversed the effects of pterostilbene on cell viability(P＜0.001),apoptosis(P＜0.001),and Nrf2 expression(P=0.022).Conclusion Pterostilbene is a compound that can effectively inhibit colon cancer cells by inhibiting the Nrf2 pathway.

Purpose To investigate the difference of resting-state functional connectivity density(FCD)between chronic primary insomnia patients and healthy controls via resting state functional magnetic resonance imaging(rs-fMRI).Materials and Methods All rs-fMRI data of 35 patients with chronic primary insomnia from Xidian Group Hospital and Xi'an Encephalopathy Hospital of Traditional Chinese Medicine,and 35 healthy controls were prospectively collected from August 2020 to December 2021.The voxel-wise FCD approach was applied to explore the differences of whole-brain functional networks between chronic primary insomnia patients and healthy controls.The relationships between FCD value and Pittsburgh sleep quality index,self-rating scale of sleep,insomnia severity index,self-rating anxiety scale and self-rating depression scale in primary insomnia patients were investigated,respectively.Results Compared with healthy controls,the decreased FCD values were showed in the right insula,bilateral anterior cingulate gyrus,left orbitofrontal middle gyrus,left dorsolateral superior frontal gyrus,right medial superior frontal gyrus and bilateral thalamus(t<-5.271,Padjust<0.05),while the increased FCD values showed in the right superior temporal gyrus,bilateral middle temporal gyrus,bilateral precuneus and left posterior cingulate gyrus(t>4.379,Padjust<0.05)in the chronic primary insomnia patients group.The FCD values of bilateral thalamus(r=-0.620,P<0.001;r=-0.562,P<0.005)and right insula(r=-0.651,P<0.001)were negatively correlated with insomnia severity index in the chronic primary insomnia patients group,respectively.Conclusion The extensive functional connectivity abnormalities are observed in primary insomnia patients via FCD analysis.These findings explain the neural mechanisms of underlying emotional regulation and cognitive impairment in chronic insomnia from the perspective of functional integration and functional separation.

Bronchopulmonary dysplasia is a common respiratory complication in premature infants.With the improvement of neonatal treatment, premature infants are surviving more than ever.However, the incidence of bronchopulmonary dysplasia remains high, which seriously affects the outcomes of premature infants.The immature lung of preterm infants are susceptible to damage from a variety of factors, which are modifiable by the early use of lung-protective strategies of respiratory support.This review focused on summarizing the research progress of early lung-protective ventilation techniques for preventing bronchopulmonary dysplasia in premature infants.

Objective:To study the risk factors of hypotension after ligation of patent ductus arteriosus (PDA) in very/extremely low birth weight infants (VLBWI/ELBWI).Method:From March 2016 to January 2021, preterm infants with birth weight <1 500 g receiving bedside PDA ligation in the neonatal intensive care unit (NICU) of our hospital were enrolled in the study. According to the occurrence of hypotension within 72 hours after ligation, the infants were assigned into non-hypotension group and hypotension group. The general status and perioperative conditions of the two groups were analyzed. Multivariate Logistic regression was used to analyze the risk factors of hypotension.Result:A total of 44 cases were enrolled, including 33 in non-hypotension group and 11 in hypotension group. Univariate analysis showed that hypotension group had significantly more cases with body weight <1 100 g during surgery and receiving preoperative high frequency oscillatory ventilation (HFOV) than non-hypotension group ( P<0.05). Multivariate Logistic regression analysis showed that weight <1 100 g during surgery ( OR=12.045, 95% CI 1.351~107.394, P=0.026) and receiving preoperative HFOV ( OR=27.832, 95% CI 1.363~568.292, P=0.031)were independent risk factors of hypotension. Conclusion:Hypotension is one of the common complications of PDA ligation in VLBWI/ELBWI. The infant's body weight during ligation and receiving preoperative HFOV are independent risk factors of hypotension.

Determining whether patients have volume-responsiveness is one of the frequently asked questions in the intensive care unit, especially in shock patients. Evaluating the volume status and volume responsiveness can help clinical medical staff accurately grasp the patient's cardiac preload, guide reasonable volume management, and help improve patient prognosis. Therefore, many non-invasive and invasive methods have been proposed to evaluate volume responsiveness. Inferior vena cava ultrasound has been widely used to guide the fluid management of critically ill patients due to its simplicity, non-invasiveness, and good repeatability. This article reviews the clinical applications of inferior vena cava ultrasound in fluid management of critically ill patients, so as to provide a reference for circulatory management of critically ill patients.
