Objective To analyze the influence of drainage volume on prognosis of acute hydrocephalus(AHC)after aneurysmal subarachnoid hemorrhage(aSAH)by continuous lumbar drainage.Methods A retrospective trial was conducted on 82 AHC patients after aSAH admitted to the First Affiliated Hospital of Chongqing Medical University between January 2017 and January 2022.In 6 months after discharge,modified Rankin Scale(mRS)score was used to evaluate the prognostic outcomes.Univariate and multivariate logistic regression analyses were performed on demographic factors,severity of subarachnoid hemorrhage(SAH)at admission,medical history,cerebral vasospasm,and lumbar drainage data.Then a nomogram prediction model was constructed.Results Univariate analysis found that World Federation of Neurosurgical Societies(WFNS)score,Hunt-Hess grade,modified Fisher grade,time for continuous lumbar drainage,shunt dependence,cerebral vasospasm,and drainage volume were factors affecting the prognosis of the patients.Then logistic regression analysis revealed that high WFNS score(OR:3.25,95％CI:1.11～9.48),high modified Fisher grade(OR:3.66,95％CI:1.08～12.35),shunt dependence(OR:15.56,95％CI:1.22～198.57),and cerebral vasospasm(OR:22.24,95％CI:3.08～160.68)were independent predictors for mRS score,while volume of continuous lumbar drainage(OR:0.57,95％CI:0.40～0.82)was an independent protective factor.ROC curve analysis indicated a good predictive performance of the model(AUC=0.898,95％CI:0.935～0.861).Internal validation through Bootstrap method demonstrated excellent discriminatory ability of the model(C-index=0.950,95％CI:0.904～0.996;adjusted C-index:0.934).Conclusion Increased volume of lumbar drainage is an independent protective factor for poor prognosis following aSAH and can improve the prognosis of SAH patients.

OBJECTIVE To explore the mechanisms of the flavonoids from new "Zhe Eight Flavors" Quzhou Fructus Aurantii(PTFC) against hepatocellular carcinoma based on the prediction of network pharmacology and experimental verification. METHODS From TCMSP, TCMID, ETCM, BATMAN-TCM and SwissTargetPrediction databases, the potential target proteins of PTFC, including naringin, narirutin and neohesperidin were collected. Based on the GeneCards, CTD, Disgenet, and OMIM databases, a set of target proteins for hepatocellular carcinoma was constructed. Taking the intersection of potential target proteins of PTFC and target proteins of hepatocellular carcinoma, key target proteins were obtained and a protein-protein interaction network was established. Besides, GO function and KEGG pathway enrichment analysis on the core target proteins was performed and a Compounds-Targets-Pathways-Disease network was constructed. Through proliferation, cloning, wound healing, and migration experiments, the effects of PTFC on the viability of HepG2 liver cancer cells were analyzed. Using fluorescence probe staining the impacts of PTFC on the mitochondrial membrane potential and apoptosis of HepG2 were observed. Finally, the validation of the regulatory effect of PTFC on the key predicted target PRKCA were carried out through RT-qPCR. RESULTS Based on network pharmacology, a total of 217 potential target proteins for PTFC were screened, with 59 intersecting target proteins related to diseases, including ALB, ESR1, PRKCA, and others. GO functional and KEGG pathway enrichment analysis revealed that the PTFC target proteins were involved in 193 biological processes and 13 cancer-related signaling pathways. Experimental results demonstrated that PTFC could impact the proliferation, cloning, wound healing, and migration abilities of liver cancer cells, leading to a decrease in mitochondrial membrane potential and promoting cell apoptosis. The results of RT-qPCR confirmed a significant downregulation of PRKCA expression by PTFC, validating the predictions made by network pharmacology analysis. CONCLUSION This study has revealed the potential molecular mechanism of PTFC treating hepatocellular carcinoma via the PRKCA target, laying the foundation for clinical application of PTFC.

Objective To compare the effectiveness of Defocus Incorporated Multiple Segments (DIMS) and High Aspheric Lenslet (HAL) defocus lenses in controlling myopia. Methods A total of 214 children and adolescents who were fitted with defocus lenses (DIMS or HAL) in our hospital from January to June 2023 were selected, including 100 cases in DIMS group and 114 cases in the HAL group. Changes in parameters such as spherical lens power, cylindrical lens power, spherical equivalent (SE), corneal curvature (K), axial length (AL), binocular accommodative response (BCC), positive/negative relative accommodation (PRA/NRA), distance/near latent phoria (DLP/NLP), and accommodative convergence to accommodation ratio (AC/A) were compared between the two groups before wearing and after wearing the lenses for 6 months, and the effectiveness of myopia control between DIMS and HAL was further compared. Results After wearing the lenses (DIMS or HAL) for 6 months, the average increase in axial length was (0.09±0.14) mm, the average increase in spherical lens power was (-0.11±0.23) D, the average increase in astigmatism was (-0.07±0.16) DC, and the average increase in spherical equivalent was (-0.15±0.24) D, with statistically significant differences observed for all these changes (t=9.24, -7.27, -6.60, -9.03, respectively, P < 0.001). Compared with parameters before wearing the lenses, statistically significant differences were noted after wearing for 6 months in spherical lens power, cylindrical lens power, SE, BCC, PRA, DLP, average K, and AL (P≤0.001), except for NRA (t=-0.12, P>0.05), NLP (t=-0.28, P>0.05), and AC/A (t=0.33, P>0.05). The differences in parameters between the two groups after wearing the lenses for 6 months showed a statistically significant difference only in the AL difference (t=4.38, P≤0.001), with no statistically significant differences observed for other parameter differences (P>0.05). Conclusion Wearing defocus lenses has a positive effect on controlling myopia, delaying axial length elongation, and maintaining binocular visual function balance.

Objective To observe the dynamic changes of cardiac lymphangiogenesis in Doxorubicin(DOX)-induced dilated cardiomyopathy(DCM)model mice,and to study the the protective mechanism of Kuoxin Decoction.Methods The DCM mouse model was established by intraperitoneal injection of DOX,and the dynamic observation was performed every week.On this basis,60 C57BL/6 mice were randomly divided into 6 groups(n=10):control group,Model group,L-KXD,M-KXD and H-KXD groups and Captopril group.After successful modeling,the KXD and the positive control drug Captopril were administered continuously for 28 days.Echocardiography was used to detect cardiac function in mice,HE staining and Masson staining were used to observe pathological and morphological changes of the heart,Whole-mount immunofluorescent staining was used to detect the expression of LYVE-1 and Podoplanin in epicardial lymphatic vessels,Western blot was used to detect the expression of VEGFR-3 protein,and qPCR was used to detect the expression of VEGFR-3 mRNA.Results DCM mice induced by DOX showed significant cardiac function decline from the third week(DOX:15 mg·kg-1,P<0.05),and significant ventricular remodeling at the fifth week(DOX:15 mg·kg-1,P<0.01);The lymphatic vessel area of the mouse heart decreased significantly from the fourth week(DOX:20 mg·kg-1,P<0.0001),and the expression of VEGFR-3 decreased significantly from the third week(DOX:15 mg·kg-1,P<0.01).Conclusion KXD can improve ventricular remodeling and cardiac function in DOX-induced DCM mice,promote cardiac lymphangiogenesis,and upregulate the expression of VEGFR-3 at protein and mRNA levels,with a better effect than captopril.DOX-induced cardiac lymphangiogenesis in DCM mice leads to severe myocardial fibrosis and weakened cardiac function,which gradually worsens with the accumulation of modeling time and dose.KXD can promote cardiac lymphangiogenesis and improve cardiac function in DOX-induced DCM mice.The mechanism may be related to the up-regulation of VEGFR-3 expression.

Objective:To observe the therapeutic effect of quercetin (QUE) on triggering receptor expressed on myeloid cells (TREM-1) activated macrophage inflammation and lipopolysaccharide (LPS) induced acute lung injury (ALI) in mice, and explore its possible mechanism.Methods:In vitro cell experiment: The primary peritoneal macrophages of mice were collected by intraperitoneal injection of 3% calcium mercaptan acetate. The collected cells were divided into blank control group, dimethylsulfoxide (DMSO) vehicle group, TREM-1 agonist group (10 μg/ml), QUE group (10 μmol/L) and TREM-1 agonist + QUE group (cells were pretreated with 10 μmol/L QUE for 30 min before adding agonist). Enzyme linked immunosorbent assay (ELISA) was used to detect the secretion of interleukin (IL)-1β, tumor necrosis factor (TNF)-α and IL-6 in the culture supernatant of primary macrophages; To observe the effect of QUE on LPS-induced TREM-1 protein levels, macrophages were divided into: normal control group, LPS group (100 ng/ml) and LPS+ QUE treatment group [macrophages were pretreated with 10 μmol/L QUE for 2 hours, and then incubated with LPS (100 ng/ml) for 16 hours]. Western blot was used to detect the expression of TREM-1 protein. In animal experiments: 80 male C57BL/6 mice were randomly divided into 4 groups (20 in each group): normal control group, ALI model group, QUE group and QUE treatment group (LPS+ QUE). In the ALI model group, the ALI model was established by intratracheal injection of 5 mg/kg LPS; The mouse ALI model was established by intratracheal injection of LPS 5 mg/kg in the QUE treatment group, and then intraperitoneal injection of 15 mg/kg QUE. The control group was given the same amount of normal saline intratracheal followed by intraperitoneal injection of DMSO, and the QUE group was given the same amount of normal saline intratracheal followed by intraperitoneal injection of 15 mg/kg QUE. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of lung tissue in each group; Inflammatory cells including IL-1β, TNF- α and IL-6 in bronchoalveolar lavage fluid (BLAF) of mice in each group were counted ; The expression of TREM-1 mRNA and protein in lung tissue of mice in each group was detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) and Western blot. Results:In vitro cell experiment: the secretion of IL-1β, TNF-α and IL-6 in the supernatant of primary macrophages in TREM-1 agonist group was higher than those in DMSO vehicle group, while the secretion of IL-1β, TNF-αand IL-6 in the supernatant of primary macrophages in TREM-1 agonist + QUE group were lower than that of TREM-1 agonist group (all P<0.001). The expression of TREM-1 protein in LPS group was higher than that in control group ( P<0.05), while the expression of TREM-1 protein in LPS + QUE group was lower than that in LPS group ( P<0.05). Animal experiments showed that compared with the control group, the ALI model group had higher lung pathological injury score, more total cells, macrophages and neutrophils in BALF and increased TNF-α, IL-6, IL-1β content (all P<0.001). The above indexes in QUE group were lower than those in ALI model group (all P<0.001). The results of qRT-PCR and Western blot showed that compared with the control group, the expression of TREM-1 mRNA and protein in the lung tissue of ALI model group was increased, while the expression of TREM-1 mRNA and protein in the lung tissue of QUE group was lower than that of ALI model group (all P<0.05). Conclusions:Quercetin can inhibit TREM-1 activation, reduce macrophage inflammatory response and LPS induced acute lung injury in mice.

Traumatic rib fractures are the most common injury in thoracic trauma. Previously，the patients with traumatic rib fractures were mostly treated non-surgically，of which 50%，especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities，being unable to retain a full-time job. In the past two decades，thanks to the development of internal fixation material technology，the surgical treatment of rib fractures has achieved good outcomes. However，there are still some problems in clinical treatment，including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans，and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore，the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association，in conjunction with national multidisciplinary experts，formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures（2021）following the principle of evidence-based medicine，scientific nature and practicality. This expert consensus puts forward some clear，applicable，and graded recommendations from aspects of preoperative imaging evaluation，surgical indications，timing of surgery，surgical methods，rib fracture sites for surgical fixation，internal fixation methods and material selections，treatment of combined injuries in rib fractures，in order to provide references for surgical treatment of traumatic rib fractures.

Objective:To carry out the Meta-integration of Intensive Care Unit (ICU) nurses' real experience of palliative care.Methods:The qualitative study that met the criteria in the Cochrane Library, PubMed, EMbase, Web of Science, China Biology Medicine Literature Service System, China National Knowledge Infrastructure (CNKI) , VIP and Wanfang Data were searched by computer from the establishment of the database to June 30, 2020. The quality of the included literature was evaluated using the critical appraisal checklist for qualitative researches of the Australia Joanna Briggs Institute (JBI) Evidence-based Health Center (2017 edition) . The collective integration method was used to integrate the results.Results:A total of 17 articles were included, involving 16 in English and 1 in Chinese. Finally, it was summarized into 11 categories, and 4 integrated results were collected, which were the complex palliative care (multiple roles of ICU nurses in palliative care, patient care, and family care) ; insufficient preparation for palliative care (lack of professional skills, communication skills and psychological preparation) ; insufficient support from palliative care organizations (inadequate psychological support, multidisciplinary team cooperation, and lack of professional palliative care service systems) ; insufficient legal support for palliative care (lack of decision-making power for palliative care, ethics and legal issues in palliative care) .Conclusions:ICU nurses lack the ability to palliative care and lack a reliable support system. Managers should pay attention to the negative experience and needs of ICU nurses for palliative care, and gradually carry out education and training to improve the level of care and the quality of life of dying patients.

Objective To investigate the value of serum lactate dehydrogenase (LDH) in advanced non-small cell lung cancer (NSCLC) treated with epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI).Methods Pretreatment LDH level,pathological characteristic,tumor staging and treatment situation of 190 advanced NSCLC patients with EGFR sensitive mutation confirmed by pathology were retrospectively collected in Zhuhai People's Hospital of Guangdong Provice from July 2011 to July 2015.All the patients were divided into LDH normal group (LDH ≤252 U/L,n =78) and elevated group (LDH ＞ 252 U/L,n =112) according to pretreatment LDH level.Inaging evaluations of the patients were performed regularly,and the progression-free survival (PFS) and overall survival (OS) were recorded.The survival curves were plotted by Kaplan-Meier method and survival difference between patients with different LDH level was compared by logrank test.Cox regression analysis was used to analyze prognostic factors for mortality.Results The objective response rate of the LDH normal group was 76.9％ (60/78),and the elevated group was 71.4％ (80/112),with no statistically significant difference (x2 =0.716,P =0.398).The disease control rate of the LDH normal group was 89.7％ (70/78),and the elevated group was 85.7％ (96/112),with no statistically significant difference (x2 =0.676,P =0.411).The median PFS of the LDH normal group was 11.5 months,and the elevated group was 9.7 months (x2 =5.92,P =0.015).The median OS was 31.0 months in the LDH normal group,and 26.1 months in the elevated LDH group (x2 =4.79,P =0.029).Both PFS and OS of patients with elevated LDH were shorter than those of patients with normal LDH.Cox multivariate regression analysis showed that tumor staging (HR =1.652,95％ CI:1.386-2.259,P =0.018),PS score (HR =2.248,95％ CI:1.507-3.846,P ＜ 0.001),carcino-embryonic antigen (CEA) level (HR =1.250,95％ CI:1.066-1.703,P =0.037) and LDH level (HR =1.771,95 ％ CI:1.324-1.947,P =0.015) were independent prognostic factors in patients with advanced NSCLC.Conclusion Pretreatment serum LDH can not affect the objective response rate and disease control rate of EGFR-TKI in the treatment of advanced NSCLC,but can affect the PFS and OS of patients.Pretreatment serum LDH is an independent prognostic factor.
