Efficacy and safety of total glucosides of paeony in treating primary Sjögren's syndrome: a propensity-matched study.

OBJECTIVE: This study aimed to evaluate the efficacy and safety of total glucosides of paeony (TGP) in patients with primary Sjögren's syndrome (pSS). PATIENTS AND METHODS: This study included 236 patients with pSS, including 118 TGP users and 118 non-users. Propensity score matching and Binary logistic regression analyses were used to minimize confounding factors and determine the association between TGP treatment and clinical variables. RESULTS: The baseline indexes of TGP users and non-users were basically the same. The median time of follow-up in the two groups was also similar (p < 0.05). Compared with non-users, TGP users showed higher rates of improvement in dry mouth and eyes and musculoskeletal involvement, as well as more significant reductions in serum alanine aminotransferase (ALT) and direct bilirubin (DBIL) levels after treatment. Logistic regression confirmed that the use of TGP was negatively correlated with the increase of ALT and DBIL in pSS patients, and the reduction in these variables was more pronounced after 2 years of treatment. The incidence of adverse reactions in the TGP users was 11.9%, which was compatible with those in non-users. CONCLUSIONS: TGP is often a safe option for treating pSS patients with musculoskeletal features and abnormal ALT levels. Besides, it can help improve dry mouth and dry eyes and decrease DBIL levels.

[Epidemiological and spatial-temporal clustering characteristics of pertussis in Hebei Province from 2013 to 2022].

Objective: To analyze the spatial-temporal epidemiological characteristics of pertussis from 2013 to 2022 in Hebei Province and to provide a reference for improving prevention and control measures. Methods: Based on the data of pertussis reported in Hebei Province during 2013-2022 to analyze the popular characteristic, the ArcGIS 10.8 software was used to construct a ring map and to perform spatial autocorrelation analysis; the SaTScan 10.1 software was used for spatial-temporal scan statistics. Results: There were 6 715 cases of the cumulative report in Hebei Province from 2013 to 2022 without death. The annual report incidence was 0.90/100 000. The overall incidence rate showed an upward trend from 2013 to 2019, and during 2020-2021, it showed a sharp decline, but in 2022, it showed a sharp increase. Summer and autumn are the peak seasons of the epidemic. The incidence was highest in age group <1 year (48.67%), and the lowest age group in age group ≥15 years (0.45%) and mainly scattered children (78.03%); the incidence about men is higher than women. Spatial autocorrelation analysis showed that the onset of pertussis has spatial clustering, and high-high clusters were found in Langfang, Baoding, and Cangzhou, the top three countries with reported incidence. The area covered by a low-low cluster was consistent with the distribution of the corresponding low-incidence areas in this study. Space-time scan detects five statistically significant areas, and three zones were concentrated in 2022. Conclusions: The incidence of pertussis in Hebei had obvious season, population, and area-specific differences. There was obvious spatiotemporal and clustering, so the control of key areas should target the characteristics of time and space.

[Patient-reported outcomes of locally advanced gastric cancer undergoing robotic versus laparoscopic gastrectomy: a randomized controlled study].

Objective: To compare the patient-reported outcomes and short-term clinical outcomes between robotic-assisted and laparoscopic-assisted radical gastrectomy for locally advanced gastric cancer. Methods: This single-center prospective randomized controlled trial was conducted in the Department of Gastrointestinal Surgery,Affiliated Hospital of Qingdao University from October 2020 to August 2022. Patients with locally advanced gastric cancer who were to undergo radical gastrectomy were selected and randomly divided into two groups according to 1∶1, and received robotic surgery and laparoscopic surgery, respectively. Patient-reported outcomes and short-term clinical outcomes (including postoperative complications, surgical quality and postoperative short-term recovery) were compared between the two groups by t test, Mann-Whitney U test, repeated ANOVA, generalized estimating equation, χ2 test and Fisher's exact test. Results: A total of 237 patients were enrolled for modified intention-to-treat analysis (120 patients in the robotic group, 117 patients in the laparoscopic group). There were 180 males and 59 females, aged (63.0±10.2) years (range: 30 to 85 years). The incidence of postoperative complications was similar between the robotic group and laparoscopic group (16.7% (20/120) vs. 15.4% (18/117), χ2=0.072, P=0.788). The robotic group had higher patient-reported outcomes scores in general health status, emotional, and social domains compared to the laparoscopic group, differences in time effect, intervention effect, and interaction effect were statistically significant (general health status: χ2 value were 275.68, 3.91, 6.38, P value were <0.01, 0.048, 0.041; emotional: χ2 value were 77.79, 6.04, 6.15, P value were <0.01, 0.014, 0.046; social: χ2 value were 148.00, 7.57, 5.98, P value were <0.01, 0.006, 0.048). However, the financial burden of the robotic group was higher, the differences in time effect, intervention effect and interaction effect were statistically significant (χ2 value were 156.24, 4.08, 36.56, P value were<0.01, 0.043,<0.01). Conclusion: Compared to the laparoscopic group, the robotic group could more effectively relieve postoperative negative emotions and improve recovery of social function in patients.

[Effects of microRNA-106b on migration and invasion of human malignant pleural mesothelioma cell NCI-H2452].

Objective: To investigate the inhibitory effect of microRNA-106b in the process of migration and invasion of human malignant pleural mesothelioma cell NCI-H2452. Methods: In April 2017, the expression level of miRNA-106b in malignant pleural mesothelioma cells (NCI-H2452, MSTO-211H, NCI-H2052) and normal mesothelial cells MeT-5A was detected and analyzed. Using NCI-H2452 cells as a model, the NCI-H2452 cell model with miRNA-106b overexpression was established by transfecting miRNA-106b mimics. The expression level of miRNA-106b in the cells was detected by real-time fluorescent quantitative PCR. The effect of miRNA-106b on the migration and invasion ability of NCI-H2452 cells was analyzed. The gene expression data of malignant mesothelioma and the downstream target gene data of miRNA-106b in public databases were analyzed to screen the downstream target genes of miRNA-106b in mesothelioma cells that affect cell migration and invasion ability, and to verify the expression of this gene in NCI-H2452 cells with miRNA-106b overexpression. Results: The expression of miRNA-106b in three MPM cells was decreased compared with MeT-5A cells (P<0.001) . The expression level of miRNA-106b was significantly increased after transfection of miRNA-106b mimics (P<0.001) . The scratch migration levels of the experimental group were 28.45%±4.37%, 38.12%±4.82% and 50.06%±8.92% at 24h, 31h and 48h, respectively. Compared with the control group, the migration level decreased by 37.48%±2.65%, 49.21%±3.45% and 68.14%±3.81% (P<0.01) . The number of cell migration and invasion decreased in the experimental group compared with the control group (P<0.001) . Public databases were used to screen and analyze the possibility that TCF21 gene, as a downstream target gene, could affect the migration and invasion ability of MPM cells. The expression level of TCF21 gene was increased after transfection of miRNA-106b mimics in NCI-H2452 cells (P=0.009) . Conclusion: MiRNA-106b can inhibit the migration and invasion of NCI-H2452 cells and increase the expression of TCF21 gene.

Endovascular treatment for acute ischaemic stroke caused by isolated internal carotid artery occlusion: treatment strategies, outcomes, and prognostic factors.

AIM: To describe the experience of endovascular treatment (EVT) of acute ischaemic stroke caused by isolated internal carotid artery (ICA) occlusion, with emphasis on treatment strategies, outcomes, and prognostic factors. MATERIALS AND METHODS: A retrospective examination was performed of 66 consecutive patients with acute moderate-to-severe stroke who underwent EVT for isolated ICA occlusion from July 2016 to June 2021. The modified thrombolysis in cerebral ischaemia (mTICI) score was used to evaluate reperfusion outcomes. A multivariate analysis was performed to identify risk factors associated with poor 90-day outcome (modified Rankin Scale [mRS] 3-6). RESULTS: The National Institutes of Health Stroke Scale (NIHSS) median score of the 66 patients at admission was 15. Twelve patients (18.2%) showed thrombus migration to the M1 segment or proximal M2 during EVT and underwent additional intracranial thrombectomy. Successful reperfusion (mTICI 2b-3) was achieved in 60 patients (90.9%) and complete reperfusion (mTICI 3) in 42 (63.6%). A poor functional outcome was seen in 27 patients (40.9%). The rate of 90-day mortality was 9.1% (6/66). Higher NIHSS scores and a lower Alberta Stroke Program Early CT Score (ASPECTS) were independently associated with poor outcomes. Complete reperfusion was the only treatment factor with a significant predictive value (adjusted odds ratio [OR] 0.03; 95% CI = 0.01 to 0.25; p=0.001). CONCLUSION: Endovascular therapy is safe and effective in patients with acute ischaemic stroke due to isolated ICA occlusion. Prevention of thrombus migration and complete reperfusion should be the aim of EVT.

Endovascular Recanalization of Symptomatic Chronic ICA Occlusion: Procedural Outcomes and Radiologic Predictors.

BACKGROUND AND PURPOSE: Endovascular recanalization has been attempted in patients with symptomatic chronic ICA occlusion, however, the heterogeneity of recanalization outcomes and the perioperative complications present challenges for the clinical application. Our aim was to evaluate the safety and efficacy of endovascular recanalization for symptomatic chronic ICA occlusion and identify potential predictors for successful recanalization. MATERIALS AND METHODS: This study included 47 consecutive patients with symptomatic chronic ICA occlusion who underwent endovascular recanalization at our institution. Patients' clinical information, radiologic characteristics, procedural results, and outcomes were recorded. Factors related to technical success were analyzed by univariate and multivariate analyses. RESULTS: The technical success rate was 74.5% (35/47); 12.8% of patients (6/47) experienced intraoperative complications, but none had permanent neurologic deficits. Three months after recanalization, 21 of the 29 recanalized patients (72.4%) and 3 of the 10 failed patients (30.0%) demonstrated improved mRS scores. Restenosis or re-occlusion occurred in 12.9% of patients (4/31) with successful recanalization. Multivariate analysis showed that tapered or blunt stump (P = .016), distal ICA occlusion segment (below the cavernous segment versus at or above the ophthalmic segment, P = .003; at the cavernous or clinoid segment versus at or above the ophthalmic segment, P = .027), and radiologic occlusion to recanalization of ≤3 months (P = .044) were significantly associated with successful recanalization. Patients were assigned points according to the coefficients of the prediction model, and the technical success rates were 0%, 46.2%, 90.5%, and 100% in patients with 1, 2, 3, and 4 points, respectively. CONCLUSIONS: Endovascular recanalization is a safe and effective treatment for symptomatic chronic ICA occlusion in selected patients. A residual stump, low levels of the distal ICA occlusion segment, and a short radiologic occlusion time were identified as positive predictors of technical success.

Automated Estimation of Quantitative Lesion Water Uptake as a Prognostic Biomarker for Patients with Ischemic Stroke and Large-Vessel Occlusion.

BACKGROUND AND PURPOSE: Net water uptake is qualified as an imaging marker of brain edema. We aimed to investigate the ability of net water uptake to predict 90-day functional outcome in patients with acute ischemic stroke and large-vessel occlusion. MATERIALS AND METHODS: A total of 295 consecutive patients were retrospectively enrolled. Automated ASPECTS-net water uptake was calculated on the admission CT. The relationship between ASPECTS-net water uptake and 90-day neurologic outcome was assessed. The independent predictors of favorable outcome (mRS score ≤2) were assessed using multivariate logistic regression analysis and receiver operating characteristic curves and stratified by the ASPECTS. RESULTS: Favorable 90-day outcomes were observed in 156 (52.9%) patients. ASPECTS-net water uptake (OR, 0.79; 95% CI, 0.70-0.90), NIHSS scores (OR, 0.91; 95% CI, 0.87-0.96), age (OR, 0.96; 95% CI, 0.94-0.99), and vessel recanalization (OR, 7.78; 95% CI, 3.96-15.29) were independently associated with favorable outcomes at 90 days (all, P < .01). A lower ASPECTS-net water uptake independently predicted a good prognosis, even in the subgroup of patients with low ASPECTS (≤5) (P < .05). An outcome-prediction model based on these variables yielded an area under the receiver operating characteristic curve of 0.856 (95% CI, 0.814-0.899; sensitivity, 76.3%; specificity, 81.3%). CONCLUSIONS: ASPECTS-net water uptake could independently predict 90-day neurologic outcomes in patients with acute ischemic stroke and large-vessel occlusion. Integrating ASPECTS-net water uptake with clinical models could improve the efficiency of outcome stratification.

Association between Infarct Location and Hemorrhagic Transformation of Acute Ischemic Stroke following Successful Recanalization after Mechanical Thrombectomy.

BACKGROUND AND PURPOSE: The association between infarct location and hemorrhagic transformation of acute ischemic stroke after mechanical thrombectomy is not understood. We aimed to evaluate the association between CTP-based ischemic core variables at admission and hemorrhagic transformation after a successful thrombectomy. MATERIALS AND METHODS: We retrospectively analyzed patients who underwent endovascular thrombectomy for acute anterior circulation large-vessel occlusion between October 2019 and June 2021. We enrolled 146 patients with visible ischemic core on pretreatment CTP who had successful reperfusion. The ischemic core infarct territories were classified into the cortical and subcortical areas and then qualitatively and quantitatively analyzed by CTP. Logistic regression and receiver operating characteristic curve analyses were performed to determine the association between ischemic core variables and hemorrhagic transformation. RESULTS: Of the 146 patients analyzed, 72 (49.3%) had hemorrhagic transformation and 23 (15.8%) had symptomatic intracerebral hemorrhage. Multivariate analysis showed that subcortical infarcts were independently associated with hemorrhagic transformation (OR, 8.06; 95% CI, 2.31-28.10; P = .001) and subcortical infarct volume was independently linked to symptomatic intracerebral hemorrhage (OR, 1.05; 95% CI, 1.01-1.09; P = .039). The receiver operating characteristic curve indicated that subcortical infarcts can predict hemorrhagic transformation accurately (area under the curve = 0.755; 95% CI, 0.68-0.82; P < .001) and subcortical infarct volume can predict symptomatic intracerebral hemorrhage (area under the curve = 0.694; 95% CI, 0.61-0.77; P = .002). CONCLUSIONS: Subcortical infarcts seen on CTP at admission are associated with hemorrhagic transformation in patients after successful thrombectomy, and subcortical infarct volume may influence the risk of symptomatic intracerebral hemorrhage.

Hypoperfusion intensity ratio correlates with clinical outcome of endovascular thrombectomy in acute ischaemic stroke patients with late therapeutic window.

AIM: To evaluate the prognostic value of the hypoperfusion intensity ratio (HIR) on 90-day clinical outcome in acute ischaemic stroke (AIS) patients with late therapeutic window. MATERIALS AND METHODS: One hundred and sixty-eight consecutive AIS patients with anterior-circulation large-vessel occlusion who underwent endovascular thrombectomy during the late window were enrolled retrospectively. Clinical data, Alberta Stroke Program Early Computed Tomography Score (ASPECTS) based on unenhanced computed tomography (CT), and perfusion parameters included ischaemic core, hypoperfusion volume, mismatch volume between core and penumbra, and the HIR were assessed and compared between patients with or without favourable outcomes (defined as modified Rankin Scale score of 0-2). Statistical analysis included binary logistic regression and receiver operating characteristic (ROC) analyses. RESULTS: A favourable outcome was achieved in 76 (45.2%) patients. In univariable analysis, age, National Institutes of Health Stroke Scale (NIHSS) score at admission, ASPECTS score, HIR, ischaemic core, and hypoperfusion volume were significantly associated with functional outcome (p<0.05). In multivariate analyses, age (OR 0.95; 95% CI 0.92-0.99), NIHSS score at admission (OR 0.89, 95% CI 0.84-0.96) and HIR (OR 0.018, 95% CI 0.003-0.113) remained as independent outcome predictors (p<0.01). The optimal threshold of HIR was 0.36 (sensitivity 70.7%, specificity 61.8%). The combination of age, NIHSS score at admission, and HIR yield good performance for outcome prediction with an area under the ROC curve of 0.815 (sensitivity 88.2%, specificity 64.1%), significantly higher than individual variable (p<0.05). CONCLUSION: Low HIR was a predictor for favourable outcome in AIS patients with late therapeutic window. Integrating HIR with clinical variables improved the ability for outcome classification.

[Chronic toxicity of Multi-walled carbon nanotubes in human pleural mesothelial cells].

Objective: To explore the chronic toxicity and its potential mechanism of multi-walled carbon nanotube (MWCNT) in human pleural mesothelial cells. Methods: A sustainable exposure of MeT-5A cells to MWCNT at 10 µg/cm(2) for one year was conducted in 2016. During the exposure, the cell images and cell proliferation was recorded every 4 weeks. The cell apoptosis, cell cycle, cell migration and cell invasion were compared between the control cells and the cells after MWCNT exposure. Finally, the gene expression was screened with Affymetrix clariom D assay, and some of the significantly differential expressed genes was verified by RT-PCR. Results: Compared with the control group, the proliferation ability of the cells in the 1-year exposed group was significantly increased, and the rate of proliferation was about 2-3 times as that in the Control Group (F=481.32, P<0.05) . MeT-5A cells all showed cell cycle arrest effect, which showed the increase of G1 phase and the decrease of s phase and G2 phase (F=14.94, P<0.05) . The apoptosis rate of cells in the treated group was significantly higher than that in the control group after 6 months (F=15.12, P<0.05) , but the early apoptosis rate and the total apoptosis rate of cells in the treated group were not significantly different from those in the control group after 1 year (F=3.97, P<0.05) . The cell migration and invasion were both promoted by MWCNT. Furthermore, the differentially expressed genes was screened, to find 2, 878 genes with more than 2 folds changes. To further verified, RT-PCR was conducted with PIK3R3、WNT2B、VANGL2、ANXA1, and their expression changes were consistent with above. Conclusion: MWCNT might have a carcinogenic potential to MeT-5A cells after the long term exposure.

[microRNA-30d can inhibit the proliferation, migration and invasion of human mesothelial cell MSTO-211H].

Objective: To investigate the inhibitory effect and molecular mechanism of microRNA-30d (miR-30d) in the process of proliferation, migration and invasion of malignant mesothelioma cell line MSTO-211H. Methods: In April 2017, the human MSTO-211H cells was used to establish miR-30d overexpressed MSTO-211H cell model by transfection of miR-30d mimics. The qRT-PCR was performed to detect the expression level of miR-30d in the cells transfected miR-30d mimics. The effects of miR-30d on the proliferation, apoptosis, migration and invasion of MSTO-211H cells were analyzed by CCK-8 experiment, flow cytometry, cell scratch experiment and Transwell method. Results: After transfection of miR-30d, the expression level of miR-30d in the MSTO-211H+miR-30d cells group was significantly higher than MSTO-211H+miR NC cells group (P<0.01) . The cell activity of MSTO-211H+miR-30d group (105.13%±2.35%) was significantly lower than MSTO-211H+miR NC cells group (115.40%±1.35%) , and the level of apoptosis (3.97%±0.36%) was significantly higher than MSTO-211H+miR NC cells group (1.47%±0.10%) (P<0.01) . The relative migration areas at 12 and 24 h of MSTO-211H+miR-30d cells group (9.35±3.16 µm(2) and 58.19±1.82 µm(2)) were significantly lower than MSTO-211H+miR NC cells group (54.42±5.26 µm(2) and 88.32±1.96 µm(2)) (P<0.01) . Compared with the MSTO-211H+miR NC cells group, the numbers of cell migration and cell invasion were reduced in the MSTO-211H+miR-30d cells group (P<0.01) . Conclusion: miR-30d can regulate the progression of malignant pleural mesothelioma by inhibiting the proliferation, apoptosis, migration and invasion of MSTO-211H cells.

[Partial superficial parotidectomy versus superficial parotidectomy for treatment of parotid benign tumors: evidence-based medicine analysis].

Objective:The aim of this study is to systematically assess the postoperative outcomes of partial superficial parotidectomy（PSP） and superficial parotidectomy（SP） by systematic literature review and Meta-analysis, and to provide a theoretical basis for the selection of the appropriate surgical approach in clinical process. Method:Relevant studies that compared the outcomes of PSP and SP for the parotid benign tumors were searched in Pubmed, CNKI and Wanfangdata databases, and Meta-analysis was performed using software RevMan 5.0. Result:24 studies were selected for the Meta-analysis. A total of 2 795 participants were included in those studies, of whom 1 301 underwent PSP and 1 494 underwent SP. The recurrence rates for PSP and SP were 1.14%（10 of 874） and 0.6%（6 of 993）, respectively. There were no statistically significant difference in recurrence rate between PSP and SP. The rates of transient facial nerve paresis for PSP and SP were 11.60%（122 of 1 052） and 27.37%（350 of 1 279）, respectively. The rates of permanent facial nerve paralysis for PSP and SP were 1.04%（6 of 579） and 4.46%（31 of 695）, respectively. The incidences of Frey's syndrome in PSP group and SP group were 9.20%（95 of 1 033） and 30.32%（409 of 1 349）, respectively. The rate of salivary fistulafor PSP and SP were 5.38%（37 of 688） and 11.25%（65 of 578）. PSP could reduce the risk for complications compared with SP. Conclusion:This systematic review with meta-analysis suggests that PSP has a similar recurrence rate as SP, but PSP can significantly reduce the postoperativecomplications.

Risk of Acute Kidney Injury with Consecutive, Multidose Use of Iodinated Contrast in Patients with Acute Ischemic Stroke.

Currently, CTA is the imaging technique most frequently used to evaluate acute ischemic stroke, and patients with intracranial large-vessel occlusion usually undergo endovascular treatment. This single-center, prospective, cohort study showed that consecutive, multidose use of contrast during CTA and DSA does not increase the incidence of acute kidney injury in patients with acute ischemic stroke, though acute kidney injury tended to have a higher incidence in the contrast multiexposure group (P = .172).

Cannulation of Occluded Inferior Petrosal Sinuses for the Transvenous Embolization of Cavernous Sinus Dural Arteriovenous Fistulas: Usefulness of a Frontier-Wire Probing Technique.

BACKGROUND AND PURPOSE: Pursuing an alternative access route for transvenous embolization of cavernous sinus dural arteriovenous fistulas can be challenging in patients with an occluded inferior petrosal sinus. We found that cannulation of even a completely occluded inferior petrosal sinus is feasible, especially when using a standard hydrophilic-polymer-jacketed 0.035-inch guidewire as a frontier-wire for probing. MATERIALS AND METHODS: From 2002 to 2017, the frontier-wire technique was tried in 52 patients with occluded inferior petrosal sinuses for transvenous embolization of cavernous sinus dural arteriovenous fistulas at our center. Technical success was defined as access into the affected cavernous sinus compartment with a microcatheter through the occluded inferior petrosal sinus and deployment of at least 1 coil. The complications and treatment outcomes were analyzed. RESULTS: The frontier-wire technique was applied in 52 patients with 57 occluded inferior petrosal sinuses (52 ipsilateral and 5 contralateral inferior petrosal sinuses). Technical success rates were 80.8% (42/52) of patients and 73.7% (42/57) of inferior petrosal sinuses. Alternative transvenous routes were used in 3 patients, and transarterial access was used in 7 patients. Complete embolization of fistulas was achieved in 82.2% (37/45) of patients in the transvenous embolization group and in 14.3% (1/7) of patients in the transarterial group. No procedure-related morbidity or mortality was observed. CONCLUSIONS: Transvenous embolization of cavernous sinus dural arteriovenous fistulas, even through a completely occluded inferior petrosal sinus, is feasible. The difficulty of passing the microcatheter can be minimized by prior probing of the occluded inferior petrosal sinus using a standard 0.035-inch guidewire; the trace of the guidewire on the roadmap image serves as a guide for microcatheter navigation through the inferior petrosal sinus on fluoroscopy.

[Dynamic investigation of nutritional risk in patients with malignant tumor during hospitalization].

Objective: To prospectively investigate the changes in nutritional status of patients with malignant tumors during hospitalization by using nutritional risk screening (NRS2002), and to analyze the correlation between the nutritional status and clinical outcomes . Methods: This was a prospective and parallel research done by multi-center collaboration from 34 hospitals in China from June to September 2014.Hospitalized patients with malignant tumors inthese departments (Department of Gastroenterology, respiratory medicine, oncology, general surgery, thoracic surgery and geriatrics)were investigated. Only the patients with age≥ 18 years and hospitalization time between 7-30 days were included. During hospitalization, the physical indexes of human bodywere measured, and the NRS 2002 scores, and monitored the nutritional support at the time points of admission and 24 hours before discharge were recorded.And whether there was a nutritional risk in hospitalized patients and its association with clinical outcomes were investigated. Results: A total of 2 402 patients with malignancies were enrolled in this study. Seventy fourpatients who did not complete NRS2002 were eliminated, and 2 328 patients were included. The number of the main diseases was the top five, including 587 cases of colorectal cancer, 567 cases of lung cancer, 564 cases of gastric cancer, 146 cases of esophageal cancer, and 119 cases of liver tumor. At the time of discharge, compared with admission, the BMI, body weight, grip and calf circumferences of patients with malignant tumor were significantly decreased (P<0.05). The total protein, albumin, prealbumin and hemoglobin were significantly lower than those at admission (P<0.05). In 2 328 patients who were completed nutritional risk screening, the rate of malnutrition at admission was 11.1% (BMI =18.5, 258/2 328) and the rate of malnutrition at discharge was 10.9% (BMI =18.5, 254/2 328), there were no significant differences (χ(2)=0.019 7, P=0.888). There were 1 204 patients with nutritional risk at admission (51.7%, NRS2002 score≥3)and 1 352 patients with nutritional risk at discharge (58.1%, NRS2002 score≥3), with significant differences (χ(2)=49.9, P<0.001). The incidence of nutritional risk in patients with colorectal, stomach, and lung tumors at discharge was significantly higher than that at admission (P<0.05). The infective complications and other complications of patients with nutritional risk were significantly greater than those without nutritional risk at admission and at discharge.ICU hospitalization stay of patients with nutritional risk was increased significantly than those without nutritional risk at admission(P=0.042). Hospitalization expenses of patients with nutritional risk was increased significantly than those of patients without nutritional risk at discharge(P<0.01). Conclusion: The patients with malignant tumor have a higher incidence rate of malnutrition at both admission and discharge and malnutritionhas correlation with adverse clinical outcomes.The aboveindicators did not improve significantly at discharge.Doctors should pay more attention to the nutritional status (screening and evaluation)of patients before discharge and use appropriate and adequate nutrition support in order to prevent the weight loss and improve the life quality of patients.

Localized Marked Elongation of the Distal Internal Carotid Artery with or without PHACE Syndrome: Segmental Dolichoectasia of the Distal Internal Carotid Artery.

BACKGROUND AND PURPOSE: Segmental intracranial dolichoectasia of the distal ICA is a feature of PHACE syndrome or a sporadic phenomenon. We evaluated the relationship between intracranial dolichoectasia of the distal ICA and PHACE syndrome and illustrated the characteristic radiologic findings of the lesions. MATERIALS AND METHODS: Intracranial dolichoectasia of the distal ICA was identified in 20 patients at our institution from 2005 to 2016 through a review of diagnostic cerebral angiography results. All radiologic images were reviewed to determine the vascular morphologic dispositions around the distal ICA, including dysplasia, mural calcification, vessel wall enhancement, lumen narrowing, and aneurysm formation. Medical records were reviewed to determine the symptoms of PHACE syndrome. Subsequently, the correlation between radiologic findings and PHACE syndrome was assessed. RESULTS: In this cohort, which had a strong female predominance (male/female ratio= 2:18), intracranial dolichoectasia had a more ipsilateral vascular morphologic disposition. Mural calcification was detected more frequently in elderly patients, whereas vessel wall enhancement was detected more frequently in younger patients. Follow-up images showed a slow progression of the lesions. However, no significant differences in the vascular morphologic disposition and brain structural changes were observed between patients with (n = 11) and without (n = 9) PHACE syndrome. CONCLUSIONS: The striking elongation and tortuosity of the distal ICA generally appeared to be a type of congenital lesion occurring early in embryogenesis as either a sporadic phenomenon or an arterial change associated with PHACE syndrome. Imaging findings revealed various mural abnormalities with a benign clinical course.

[Extracapsular dissection versus superficial parotidectomy for treatment of parotid benign tumors: evidence based medicine analysis].

Objective:The aim of this study is to systematically assess the clinical outcomes of extracapsular dissection (ECD) and superficial parotidectomy (SP), and to provide evidences for the clinical decision for treatment of parotid gland benign tumors. Method:Relevant studies that compared the outcomes of extracapsular dissection and superficial parotidectomy for the parotid benign tumors were searched in Pubmed, CNKI and Wangfang data databases, and Meta-analysis was performed using software RevMan 5.0. Result:Fifteen studies were selected for the Meta-analysis. A total of 2 929 participants were included in those studies, of which 1 796 underwent ECD and 1 133 underwent SP. The recurrence rates for ECD and SP were 1.29% (23 of 1 776 cases) and 1.48% (16 of 1 081 cases), respectively. There were no statistically significant in recurrence rate between ECD and SP. The rates of transient facial nerve paresis for ECD and SP were 5.48% (74 of 1 350) and 22.94% (139 of 606), that of permanent facial nerve paralysis were 0.66% (8 of 1 221) and 2.71% (15 of 554). The incidences of Frey's syndrome in ECD group and SP group were 1.91% (26 of 1 360) and 16.71% (111 of 664), that of fistula in were 0.53% (5 of 946) and 2.96% (10 of 338). ECD could reduce the risk for complications compared with SP. Conclusion:This systematic review with Meta-analysis suggests that ECD has a similar recurrence rate as SP with fewer postoperative complications. ECD may be considered as an alternative surgical modality for select benign parotid tumor.

Transcultural adaptation and validation of the Chinese version of the intermittent and constant osteoarthritis pain (ICOAP) measure in patients with knee osteoarthritis.

OBJECTIVE: This study aimed to translate and adapt the intermittent and constant osteoarthritis pain (ICOAP) measure into the Chinese language (ICOAP-C), and to study its psychometric properties in patients with knee osteoarthritis (OA). DESIGN: The ICOAP was translated and cognitively pretested following internationally recommended guidelines. The reliability, including the internal consistency and the test-retest reliability, was then evaluated in 108 outpatients with knee OA. The validity was assessed by comparing the ICOAP-C with the Western Ontario and McMaster Universities Osteoarthritis Index Pain Subscale (WOMAC-PS), the Knee Injury and Osteoarthritis Outcome Score Pain Short-Form (KOOS-PS), and pain on a visual analogue scale (VAS). Seventy-four patients undergoing total knee arthroplasty (TKA) participated in the evaluation of the responsiveness of the ICOAP-C over a 6-month period. RESULTS: All participants completed the questionnaires, and no floor or ceiling effects were found. All ICOAP-C scales exhibited satisfactory internal consistency. The intraclass correlation coefficients (ICCs) were excellent, i.e., 0.932 for "total pain", 0.908 for "intermittent pain" and 0.892 for "constant pain". Regarding the convergent validity, the ICOAP-C scores exhibited strong correlations with the WOMAC-PS and moderate correlations with the KOOS-PS and the VAS. The responsiveness of the ICOAP-C at 6 months after TKA was good [standardized response mean (SRM) range: 0.94-1.20; effect size (ES) range: 1.41-1.71]. CONCLUSIONS: The ICOAP-C exhibited good reliability, validity, and responsiveness. This scale is a reliable instrument for evaluating the pain experiences of patients with knee OA and is useful for outcome measurement in clinical research.

Cross-cultural translation of the Lysholm knee score in Chinese and its validation in patients with anterior cruciate ligament injury.

BACKGROUND: The Lysholm Knee Score (LKS) is widely used and is one of the most effective questionnaires employed to assess knee injuries. Although LKS has been translated into multiple languages, there is no Chinese version even though China has the largest population of patients with knee-joint injuries. The objective of our study was to develop the Chinese version of LKS (C-LKS) and assess its reliability, validity and responsiveness in Chinese patients with anterior cruciate ligament (ACL) injuries. METHODS: Study participants were mainly recruited among patients with ACL injuries scheduled for arthroscopic ACL reconstruction at our hospital. First, we developed the C-LKS in a five-step translation and cross-cultural adaptation procedure. Next, we calculated the Cronbach's alpha, intraclass correlation coefficient (ICC), Pearson's correlation coefficient (r), effect size (ES), and standardized response mean (SRM) to evaluate the reliability, validity, and responsiveness of C-LKS respectively. RESULTS: Overall, 126 patients with ACL injuries successfully completed the questionnaires. Acceptable internal consistency (Cronbach's alpha = 0.726) as well as excellent test-retest reliability (ICC = 0.935) was found for C-LKS. Good or moderate correlation (r = 0.514-0.837) was determined among C-LKS and International Knee Documentation Committee Subjective Knee Form (IKDC), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), physical subscales of SF-36; C-LKS also had fair or moderate correlation (r = 0.207-0.462) with the other subscales of SF-36, which adequately illustrated that good validity was included in C-LKS. In addition, good responsiveness was also observed in C-LKS (ES = 1.36,SRM = 1.26). CONCLUSIONS: We have shown that our developed C-LKS questionnaire is reliable, valid and responsible for the evaluation of Chinese-speaking patients with ACL injuries and it would be an effective instrument.
