Objective To search and evaluate the relevant evidence of blood purification and anticoagulant management of perioperative liver transplantation patients,and to summarize the best evidence,so as to provide evidence-based evidence for clinical blood purification and anticoagulant management practice.Methods Evidence-based questions were determined.Systematic search was conducted on relevant domestic and foreign databases and websites for clinical decisions,guidelines,evidence summaries,system evaluations,and expert consensuses related to blood purification anticoagulation management.The retrieval period is from the establishment to May 2,2023.Literature screening,quality evaluation and evidence summary were conducted by 2 researchers.Results A total of 17 articles were included,including 2 clinical decisions,3 guidelines,2 evidence summaries,4 systematic evaluations and 6 expert consensuses.24 pieces of best evidence were summarized from 6 dimensions,including coagulation function evaluation,anticoagulant strategy,mode selection,vascular access,standardized operation implementation points and personnel organization management.Conclusion The best evidence was summarized in the study on perioperative blood purification and anticoagulant management of liver transplantation,which can provide evidence-based basis for clinical medical staff to implement anticoagulant management.However,it is necessary to further carry out evidence-based practice of perioperative blood purification and anticoagulant management of liver transplantation to verify its anticoagulation effect and nursing safety in clinical practice.

Objective To analyze the TCM syndrome distribution and prescription law of inpatients with Sj?gren syndrome(SS)complicated by lung interstitial disease(ILD)using data mining methods.Methods The clinical data of SS-ILD inpatients who met the screening criteria from January 2010 to December 2021 at Guang'anmen Hospital,China Academy of Chinese Medical Sciences were collected.A statistical analysis of TCM syndrome type and basic information,clinical manifestation,tongue and pulse,laboratory examination,TCM prescription and so on was conducted.Results Totally 87 patients were included.There was no significant difference in gender,age,age of onset,disease course or smoking history across patients with distinct syndrome types.Patients with syndrome of combination of dryness and dampness had the highest probability of drinking history(P<0.05).There were substantial differences between syndrome types in the major complaints of xerostomia,joint swelling and pain,chest tightness,cough and joint swelling(P<0.05),but no significant differences in ILD special symptoms,tongue or pulse.The level of urea nitrogen was highest in patients with yin deficiency internal heat syndrome(P<0.05),with no significant difference in other laboratory data.There were 79 prescriptions and 217 kinds of Chinese materia medica in total.High-frequency medications were primarily used to strengthen the spleen and replenish qi,nourish yin and clear heat,nourish blood and promote blood circulation,mainly with neutral property,sweet taste,the main meridians were lung meridians,liver meridians and spleen meridians.The commonly used medicine matched the pathogenesis of deficiency and excess,and the core prescription was a modified combination of Bazhen Decoction and Yangyin Qingfei Decoction.Conclusion The TCM syndrome of SS-ILD is a mixture of deficiency and excess,with qi and yin deficiency as the foundation,turbid phlegm and blood stasis as the superficiality,lung,liver and spleen as the disease's locations.Clinical treatment of replenishing qi and nourishing yin,resolving phlegm,removing blood stasis,and dredging collaterals should be the general guidance.

AIM:To evaluate the effect of optical amplification on macular retinal thickness measurements in myopic eyes of children and adolescents using optical coherence tomography(OCT).METHODS:A total of 68 cases(126 eyes)of children and adolescents aged 6 to 18 years old attending our optometric center from April 2023 to January 2024 were selected. They were divided into 44 cases(83 eyes)in the mild myopia group(-0.50 D0.05). In the moderate myopia group, the differences between the retinal thickness in each quadrant of the macula and the mean retinal thickness before and after correction were statistically significant(all P<0.001). Before correction, there was a significant difference in retinal thickness on the temporal side of the outer ring and above the outer ring of the macula in both groups(P=0.019, 0.035). However, retinal thickness in the other quadrants was not statistically different between the two groups(all P>0.05). There were significant differences between the two groups in the macular fovea, the nasal side of the inner ring, the temporal side of the inner ring, the upper inner ring, the lower inner ring, the nasal side of the outer ring, and the mean retinal thickness after correction(all P<0.05). Before correction for optical amplification, retinal thickness of the outer ring of the macula was positively correlated with SE(all P<0.05)and negatively correlated with AL(all P<0.05). By correction, a significant negative correlation was found between the macular fovea, the inner ring, and the mean retinal thickness with SE(all P<0.05). In addition, retinal thickness in all quadrants of the macula was positively correlated with AL(all P<0.001).CONCLUSION:The optical amplification affects the accuracy of retinal thickness measurements in the macular region of myopic eyes of children and adolescents, and the effect becomes more significant as the AL increases.

Objective To investigate the application effects of different myocardial protective solutions in total thoracoscopic minimally invasive aortic valve replacement surgery.Methods The clinical data of 72 patients with total thoracoscopic minimally invasive aortic valve replacement surgery in this hospital from May 2020 to January 2024 were analyzed retrospectively.The patients were divided into the St Thomas cardioplegia group(STH group,n=13),del Nido cardioplegia group(DN group,n=24),histidine tryptophan ketoglutar-ate solution group(HTK group,n=35)according to the different myocardial protective solutions.The levels of lactate(Lac)before and during surgery,the highest levels of myocardial creatine kinase isoenzyme(CK-MB),high-sensitivity troponin T(TnT)and creatinine(Cr)before operation,on the operative day and after surgery as well as the duration of extracorporeal circulation,aortic cross-clamping time,maximum flow rate,minimum bladder temperature,cardioplegia perfusion times,number of defibrillation after aortic de-clamping,postoperative ventilator assisted time,ICU stay duration and postoperative hospitalization duration were com-pared among the three groups.Results Except for 1 case of HTK was discharged automatically after surgery,the other 71 cases recovered and discharged according to the doctor's advice.There were no statistically signif-icant differences in the age,body weight,extracorporeal circulation time,aortic blocking time,maximum flow volume of extracorporeal circulation,minimum bladder temperature of extracorporeal circulation,Lac before extracorporeal circulation,highest Lac during extracorporeal circulation,assistant time of postoperative venti-lator,ICU stay duration,postoperative hospitalization duration,serum Cr before operation,Cr on operative day,preoperative TnT,postoperative TnT on operative day,postoperative highest TnT,preoperative CK-MB,postoperative CK-MB on operative day and postoperative highest CK-MB among the three groups(P＞0.05).There were statistically significant differences in the defibrillation ratio after aortic de-clamping and perfusion frequency of myocardial protective solution(P＜0.05).There was statistically significant difference in the perfusion frequency of myocardial protective solution in pairwise comparison among groups(P＜0.05),and the defibrillation ratio after aortic de-clamping had statistical difference between the DN group and HTK group(P＜0.05).Conclusion DN,STH and HTK all have good myocardial protective effect in total thoraco-scopic minimally invasive aortic valve surgery.HTK has the advantages of less perfusion times and decreasing the operative procedures compared with DN and STH;DN has the advantage of lower use for electrical defib-rillation correcting arrhythmias after aortic opening over HTK.

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.

Objective To gain insights into the supportive care needs of liver transplant recipients,in order to provide references for the formulation of effective and targeted intervention strategies.Methods Phenomenological research method was employed to conduct semi-structural in-depth interviews with 16 liver transplant recipients in the liver transplant center of a tertiary hospital in Shanghai from November 2021 to April 2022.Colaizzi 7-step analysis method and Nvivo software were used to analyze and extract the themes.Results 5 themes were extracted,including symptom management needs,longing for the perception and avoidance of recurrence risk,disease information management needs,emotional and psychological support and the return to social roles.Conclusion The physical distress and burden of liver transplantation recipients coexist.Although the initiative to seek medical treatment is high,the perception level of disease recurrence risk is not high.In order to meet the needs of liver transplant recipients and improve their quality of life,it is necessary to strengthen the health education of disease symptom management and related risk factors,pay attention to psychological counseling and strengthen social support,and provide targeted treatment care.

Objective： ：To investigate the expression of miR-137 in cervical cancer tissues and cells, and to explore its effect on proliferation, migration and invasion of cervical cancer cells as well as the mechanisms. Methods： ：Thirty-two pairs of cervical cancer tissues and corresponding para-cancerous tissues that surgically resected at the Department of Gynecology and Obstetrics of Dongguan People's Hospital from January 2017 to March 2018 were collected for this study. In addition, cervical cancer cell lines C33A, HeLa, SiHa and cervical epithelial immortalized cell line H8 were also collected. The expression of miR-137 in cervical cancer tissues and cell lines was detected by RT-PCR. miR-137 mimics and miR-137 NC were respectively transfected into C33Aand HeLa cells, and the effects of miR-137 over-expression on proliferation, migration and invasion of cervical cancer cell lines were observed by CCK-8 and Transwell assay. Luciferase reporter gene assay and WB were used to determine the relationship between miR-137 and Wnt5a in cervical cancer. Wnt5a over-expression vector was constructed, and the effects of simultaneous over-expression of Wnt5a and miR-137 on proliferation, migration and invasion of C33Aand HeLa cells were observed. Results： ：The expression level of miR-137 was significantly down-regulated in cervical cancer tissues and cell lines, as compared to para-cancerous tissues and H8 cells (all P<0.05). The over-expression of miR-137 significantly inhibited cell proliferation, migration and invasion of C33A and HeLa cells (all P<0.05). Moreover, Wnt5a was identified as a target of miR-137 by luciferase reporter gene assay. Furthermore, Wnt5a over-expression, to a certain degree, attenuated the suppressive effects of miR-137 on the proliferation, migration and invasion of C33A and HeLa cells. Conclusion： ：miR-137 can inhibit the proliferation, migration and invasion of cervical cancer cells via targeting Wnt5a, which may be an effective target for the treatment of cervical cancer.

Objective To summarize and analyze the perioperative complications of irreversible electroporation (IRE) ablation in treating tumors at different locations and to discuss their managements. Methods A total of 200 patients with tumors, including pancreatic tumor (n=71), liver tumor (n=64) and other tumors (n =65), were enrolled in this study. All patients received IRE ablation treatment. The perioperative complications were recorded and the data were statistically analyzed. The causes of severe complications and the treatment of complications were discussed. Results None of the patients died during the course of IRE ablation procedure. Severe postoperative complications occurred in the patients with pancreatic tumor or liver tumor, including duodenal artery bleeding in 3 patients with pancreatic tumor, which occurred at 10 days, 11 days and 15 days after IRE ablation respectively, and gastrointestinal bleeding (n =1) and biliary septic shock (n=1) in 2 patients with liver tumor, which occurred at 9 days after IRE ablation, the clinical symptoms were controlled after interventional embolization and/or vascular ligation together with anti-infective therapy. All minor complications were relieved after symptomatic treatment within 14 days. Conclusion IRE ablation has less systemic inflammatory response, and both the intraoperative and postoperative adverse reactions can be easily controlled, besides, IRE ablation has higher clinical safety. Although IRE ablation procedure may damage the internal or peripheral vessels of the pancreatic tumor, this severe complications can be effectively avoided if proper measures are adopted based on the causes of complications.

Objective To investigate the effects of dexmedetomidine on acute lung injury induced by hind limb ischemia-reperfusion in rats. Methods Sixty healthy male Wistar rats were randomly allocated into 4 groups: group C(control), group I-R(ischemia-reperfusion), group Pre-Dex(dexmedetomidine)and group Post-Dex. The morphological changes of the lung tissues were observed under light microscope , and polymorphonuclear neutrophils (PMN) in alveolar septum were counted. Meanwhile, lung coefficient, arterial partial PaO2, lung levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, interleukin (IL)-10, and malondialdehyde (MDA) were measured. Results Rats in the I-R group were resulted in the damage of the lung tissues. The rats in group Pre-Dex and group Post-Dex were featured with obvious mild lung injury. TNF-α、IL-6、IL-10 and MDA in lung levels were significantly increased in group I-R , Pre-Dex and Post-Dex. TNF-α, IL-6 and MDA in the lung were significantly decreased in group Pre-Pex and group Post-Dex. IL-10 was increased in group Pre-Dex and group Post-Dex. Conclusions Inflammatory response and oxidative stress are involved in the pathogenesis of acute lung injury induced by hind limb ischemia-reperfusion in rats. Dexmedetomidine attenuated the lung injury through anti-inflammation and anti-oxidation.

Objective To analyze the characteristics of clinical manifestations, risk factors, therapies and acute outcomes in patients with cerebral venous sinus thrombosis complicated by cerebral hemorrhage. Methods Seventy-five patients with cerebral venous sinus thrombosis were included in the study. According to the radiological findings on the brain image, patients were divided into two subgroups:cerebral hemorrhage group and non-hemorrhage group. The demo?graphic data, potential risk factors, clinical manifestations, radiological features, therapeutic strategies and acute out?comes were compared between two subgroups, and high risk factors were also analyzed. Results There were seventy-five patients with cerebral venous sinus thrombosis in the present study. Twenty-eight patients of them (37.2%) had cerebral hemorrhage whereas the remaining forty-seven patients (62.7%) did not have cerebral hemorrhage. Pregnancy/puerperi?um were significantly higher in patients with cerebral hemorrhage (with vs without;28.6%vs. 6.4%, P=0.015), while in?fection was markedly higher in patients without cerebral hemorrhage (with vs without;7.1% vs. 29.8%, P=0.021). Head?ache (92.9% vs. 70.2%, P=0.021), unconsciousness (25.0% vs. 6.4%,P=0.034), seizures (53.6% vs. 19.1%, P=0.002) and motor deficits (35.7% vs. 12.8%, P=0.019) were more common in patients with cerebral hemorrhage. Moreover, mul?tiple sinus involvement (1.4% vs. 44.7%, P=0.024) was significantly higher and the acute outcomes(mRS≥3: 46.4%vs.17.0%, P=0.006)were poorer in patients with cerebral hemorrhage. Binary Logistic analysis showed that pregnancy/pu?erperium (P=0.004) and multiple sinus involvement were positively, whereas infection was negatively correlated with cere?bral venous sinus thrombosis and hemorrhage ( P=0.007;P=0.03). Conclusions Pregnancy/puerperium, headache, uncon?sciousness, seizures, motor deficits and multiple sinus involvement are more frequently in patients with cerebral venous sinus thrombosis and hemorrhage, and the acute outcomes are poorer in patients with cerebral venous sinus thrombosis complicated by cerebral hemorrhage.
