Curative effects of traditional Chinese medicine paste combined with Baduanjin in treatment of osteoporotic vertebral compression fracture after PVP / 药学实践杂志

Objective To study the curative effects of traditional Chinese medicine paste combined with Baduanjin in treatment of osteoporotic vertebral compression fracture (OVCF) after percutaneous vertebroplasty (PVP). Methods 120 OVCF patients treated with PVP in our hospital from January 2016 to September 2017 were divided into the observation group (60 cases) and the control group (60 cases) according to the random number table method. The control group was given calcium carbonate D3 chewable tablets orally with routine guidance. In addition to the same treatment as the control group, the observation group received the traditional Chinese medicine paste orally with Baduanjin exercise. Both groups were treated for 6 months and followed-up for 3 years. The curative effects in the two groups after 6 months treatment and the low back pain after 1, 3 and 6 months of treatment were recorded. The changes of bone mineral density (BMD), kyphosis angle (Cobb angle), anterior wall height of vertebral body (AVBH) and level of bone metabolism indexes in the two groups were compared before and after treatment for 6 months. The follow-up times and the incidences of push-back fracture after PVP during follow-up were recorded. Results After 6 months of treatment, the clinical cure rate of the observation group was 73.33%, which was higher than 53.33% of the control group(P<0.05). Compared with pretreatment, the scores of visual analogue scale (VAS) in the two groups gradually decreased after 3 and 6 months of treatment, and the observation group had a lower scores than the control group (P<0.05). After 6 months treatment, BMD and AVBH of lumbar vertebrae and femoral neck in both groups increased, and the observation group was higher than that in the control group. The Cobb angle and serum levels of Type I procollagen degradation products (β-Cross I), the n-terminal middle osteocalcin (N-MID Ost) and parathyroid hormone (PTH) decreased in both groups, and the observation group was lower than those in the control group (P<0.05). There was no significant difference in fracture incidence after PVP in the year 1, year 1 to 3 follow up between the two groups (P>0.05). During the 3 years follow-up, the incidence of push-body fracture after PVP in the observation group was 3.33%, which was lower than that in the control group 20.00%( P<0.05). Conclusion Traditional Chinese medicine paste combined with Baduanjin reduced the serum levels of β-Cross I, N-MID Ost and PTH, regulated bone metabolism, improved BMD and AVBH of lumbar vertebrae and femoral neck, reduced Cobb angle, promoted the recovery of lumbar function, alleviated patients' back pain, lowered the incidence of push-body fracture after PVP. The curative effects were remarkable.

Vasculink iPhone Application and Risk Prediction Model for Groin Complication in Vascular Surgery.

BACKGROUND: Postoperative groin complication is a common cause of morbidity in vascular surgery. Prophylactic wound adjuncts addressing this issue have been shown to reduce complications in high-risk patients, but their widespread implementation is limited by their high cost. This study introduces a risk prediction model for patients at a high risk for groin complication which can be accessed through the iPhone application, Vasculink. METHODS: A literature search identified risk prediction models for groin complication in vascular surgery. Odds ratios of risk factors that were present in at least 2 published models were calculated with a pooled effect size. The weighted risk for each factor was used to create our model and a cutoff point defining high risk patients was chosen. The initial model was assessed and validated using a split-sample methodology on a cohort identified via a retrospective chart review of all patients undergoing open vascular surgery at our institution between 2017 and 2020. Model performance was assessed using the C-statistic. RESULTS: Risk factors included in our model were female gender, body mass index ≥28 kg/m2, ever-smoker, reoperation, use of prosthetic, emergency, and end-stage renal disease. Of 216 patients, 131 were at a high risk. The overall groin complication rate was 43%, and specific complication rates were 27% infection, 14.8% seroma, and 6.9% hematoma. Our model's sensitivity and specificity were 92.47% and 60.98%, respectively. The C-statistic is 0.768. CONCLUSIONS: By using risk factors identified in the literature we have been able to establish a highly sensitive risk prediction model for groin complication following open vascular surgery. By incorporating our model into an iPhone application, Vasculink, we hope to facilitate preoperative decision making regarding the use of prophylactic wound adjuncts.

Objective:To compare the clinical results of different endovascular thrombus reduction techniques in the treatment of acute lower extremity arterial thrombosis.Methods:The clinical data of 96 consecutive patients with acute femoral popliteal arterial thrombosis who were treated with catheter directed thrombolysis (CDT) and mechanical thrombus aspiration system (PMT) between Jan 2016 and Dec 2018 at Cangzhou People's Hospital and Peking University People's Hospital were retrospectively analyzed.Results:Ninty-six patients underwent thrombolytic surgery,including 36 with CDT thrombolysis, 28 with AngioJet aspiration alone and 32 with Rotarex aspiration alone. Angiojet thrombus aspiration reduced thrombus rate by 89.3% (25/28) and clinical success rate by 92.8% (26/28).The thrombus reduction rate of Rotarex group was 87.5% (28/32), and the clinical success rate was 96.8% (31/32). In the CDT thrombolytic group, the thrombolytic reduction rate was 61.1% (22/36), including 8 patients who underwent thrombectomy and 6 patients with PMT, with a clinical success rate of 86.1% (31/36). The rate of distal arterial embolization, puncture point and local subcutaneous hematoma and vascular rupture was 21.4%, 10.7% and 2.1%, respectively. There were no amputation cases reported during a mean 13 months follow-up.The survival rate was 97.9%. The first-stage patency rate of 67.8%, while the second-stage artery patency rate of 85.7% during the follow-up.Conclusion:Compared with CDT, PMT has higher efficiency and lower complication rate in the treatment of acute lower extremity arterial thrombosis.

Clinical application of the 25 electrodes electroencephalogram system in detecting temporal epileptiform discharges in patients with epilepsy / 中华神经科杂志

Objective:To compare the difference of epileptiform discharges detection in patients with epilepsy between the 25 electrodes electroencephalogram (EEG) system proposed by the International Federation of Clinical Neurophysiology in 2017 and the previous 19 electrodes EEG system.Methods:Patients suspected of epilepsy or with confirmed epilepsy who need a follow-up EEG were collected in Zhongshan Hospital, Fudan University from March 2018 to November 2019, and conventional video-EEG recording was performed on all patients for two hours with the standard 25 electrodes EEG system. Two neurophysiologists reviewed the recordings blindly using the 19 electrodes system and the 25 electrodes system, marking the epileptiform discharges and their amplitudes. Finally, the data were statistically analyzed.Results:A total of 403 patients were included in the study, in which 263 cases were diagnosed as epilepsy, including 129 cases of generalized epilepsy, 115 cases of temporal lobe epilepsy, 13 cases of frontal lobe epilepsy, two cases of parietal lobe epilepsy and four cases of occipital lobe epilepsy. In 115 temporal lobe epilepsy patients, 76 (66.09%) and 100 (86.96%) records were detected epileptiform discharges by the 19 or 25 electrodes EEG system respectively, and the difference was statistically significant (χ2=13.939, P<0.001). While in patients with non-temporal lobe epilepsy, there was not statistically significant difference between the two systems. In 76 patients whose temporal epileptiform discharges were detected by the two systems, the amplitudes of epileptiform discharges in the newly-added inferior temporal electrodes (F9/F10, T9/T10, P9/P10) and the original temporal electrodes (F7/F8, T7/T8, P7/P8) were (61.53±22.64) μV and (48.25±20.90) μV, respectively, with statistically significant difference between the two groups ( t=5.486, P<0.001). In patients with abnormal [79.59% (39/49) vs 61.22% (30/49), χ2=3.967, P=0.046] and normal [95.45% (42/44) vs 70.45% (31/44), χ2=9.724, P=0.003] imaging, the ability of the 25 electrodes EEG system to detect epileptiform discharges was higher than that of the 19 electrodes EEG system. Conclusion:The 25 electrodes EEG system can significantly improve the detection ability of temporal epileptiform discharges in patients with epilepsy, which is recommended for regular use to increase the detection ability of temporal area abnormal wave and assist the diagnosis and treatment of epilepsy.

Visit-to-Visit Variability of Lipids Measurements and the Risk of Stroke and Stroke Types: A Prospective Cohort Study / 대한뇌졸중학회지

Background@#and Purpose Previous studies suggested increased visit-to-visit variability of total cholesterol (TC) is associated with stroke. This study aimed to investigate the associations of various lipids measurements variability and the risk of stroke and stroke type (ischemic and hemorrhagic stroke). @*Methods@#Fifty-one thousand six hundred twenty participants in the Kailuan Study without history of myocardial infarction, stroke, and cancer who underwent three health examinations during 2006 to 2010 were followed for incident stroke. Variability in TC, triglycerides, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) measurements were measured using the coefficient of variation (CV), standard deviation (SD), variability independent of the mean (VIM), and average real variability (ARV). @*Results@#During a median of 6.04 years of follow-up, 1,189 incident stroke (1,036 ischemic and 160 hemorrhagic stroke) occurred. In the multivariable-adjusted model, the hazard ratio (HR) comparing participants in the highest versus lowest quartile of CV of HDL-C were 1.21 (95% confidence interval [CI], 1.02 to 1.45; P for trend=0.013) for ischemic stroke. The highest quartile of CV of LDL-C was associated with 2.17-fold risk of hemorrhagic stroke (HR, 2.17; 95% CI, 1.25 to 3.75; P for trend=0.002) compared with the lowest quartile. We did not observe any significant association between TC and triglycerides variability with any of stroke. Consistent results were obtained when calculating variability index using SD, VIM, or ARV. @*Conclusions@#These findings suggest the high visit-to-visit HDL-C and LDL-C variability were associated with an increased incidence of ischemic and hemorrhagic stroke, respectively.

Objective@#To evaluate the efficacy and safety of Oryz-Aspergillus enzyme and pancreatin tablets (Combizym®) in the treatment of postprandial distress syndrome (PDS) in the elderly, compared with gastrointestinal motility drugs.@*Methods@#A prospective randomized controlled trial was designed and registered in the China Clinical Trials Registry (ChiCTR-IPR-16008185). The elderly patients with PDS were randomly divided into three groups, including Mosapride group with Mosapride citrate tablets 5 mg 3 times per day for 2 weeks; Combizym® group with Combizym tablets 244 mg 3 times per day for 2 weeks; combined treatment group with both drugs and same doses for 2 weeks. The modified Nepean dyspepsia index (NDSI) score, discomfort intensity score and PDS score were calculated on patients before treatment, at the end of first and second week of treatment, as well as 4 weeks after treatment finished, respectively. Adverse effects were evaluated.@*Results@#A total of 323 patients from 16 tertiary hospitals in China were enrolled in this study. Among them, 105 patients were in Mosapride group, 109 in Combizym® group and 109 in combined treatment group. There were 148 males (45.8%) and 175 females (54.2%) with median age 71.4±9.0 years (60-100 years). Baseline characteristics of three groups were comparable. After treatment, the NDSI scores in three groups all decreased significantly (P<0.001), while they were similar between groups (P>0.05). The discomfort intensity score and PDS score in three groups showed a significant reduction after treatment (P<0.001), especially in the combined treatment group. Compared with Mosapride group, the scores in Combizym® group decreased significantly after one or two weeks [discomfort intensity score: after one week, 4.0(2.5, 8.0) vs. 6.0(3.0, 10.0); after two weeks, 3.0(0.0, 5.0) vs. 4.0(2.0, 6.0); all P<0.05. PDS score: after one week, 6.0(3.0, 9.0) vs. 7.0(3.5, 10.5); after two weeks, 3.0(0.0, 5.0) vs. 4.0(2.0, 7.0); all P<0.05]. The efficacy rate in all patients after first week of treatment was over 15.0%. The efficacy rates after two weeks were 55.2%, 68.8% and 73.4% in Mosapride group, Combizym® group and combined treatment group, respectively. After two week treatment, the efficacy rates in Combizym® group (P=0.041) and combined group (P=0.006) were higher than that of Mosapride group. The recurrence rate of Mosapride group was 9.5%, which was significantly higher than that of Combizym® group (1.8%, P<0.05) and combined treatment group (1.8%, P<0.05). There were no serious adverse effects in the three groups.@*Conclusions@#The efficacy of Oryz-Aspergillus enzyme and pancreatin tablets is comparable with that of Mosapride in elderly PDS patients, with fewer adverse effects and low recurrence rate.

Objective To investigate the risk factors predicting pathology grade upgrading after radical prostatectomy using the 2014 International Society of Urologic Pathology (ISUP) grading system.Methods A total of 205 patients who underwent biopsy and radical prostatectomy from January 2017 to December 2018 were reviewed retrospectively.The median and range of the patients' age,PSA level,prostate volume,number of biopsy core examined,Gleason score and ISUP grade were 66 (45-81) years old,17.16(0.89-1254.00)ng/ml,36.4(4.1-152.1) rnl,10(1-15),7(6-10),and 3(1-5) respectively.The patients were divided into group of upgrading ISUP grade and group without upgrading ISUP grade.Multivariate Logistic regression analysis and receiving operating characteristic curve analysis were performed to identify predictors of ISUP upgrading and determine the optimal cut off value respectively.Result The median and range of Gleason score and ISUP grade after radical prostatectomy were 7 (6-10),and 3 (1-5) respectively.The radical prostatectomy ISUP grade upgraded in 73 (35.6％) out of 205 cases when compared with biopsy ISUP grade.Radical prostatectomy ISUP grades were concordant in 91 cases (44.4％) and downgraded in 41 cases(20.0％).Of 101 with biopsy ISUP grades less than or equal to 2,the ISUP grade of radical prostatectomy upgraded in 58 cases (57.4％),while radical prostatectomy ISUP grade upgraded in only 18 (26.9％) of 67 patients with biopsy ISUP grades of 3 or 4.Biopsy ISUP grades represent an independent predictor for ISUP grade upgrading after radical prostatectomy (OR =0.496,P ＜ 0.001).Conclusion Patients with biopsy ISUP grades less than or equal to 2 are at great risk of ISUP grade upgrading after radical prostatectomy.

Intravoxel Incoherent Motion Diffusion-weighted MR Imaging for Early Evaluation of the Effect of Radiofrequency Ablation in Rabbit Liver VX2 Tumors.

RATIONALE AND OBJECTIVES: This study aims to investigate the value of intravoxel incoherent motion (IVIM)-derived parameters for early evaluation of the efficiency of radiofrequency ablation (RFA) treatment for rabbit liver VX2 tumor. MATERIALS AND METHODS: Eighteen rabbit liver VX2 tumor models were constructed, and computed tomography-guided RFA was performed. One day before and 7 days after RFA, 18 models underwent magnetic resonance imaging, including contrast-enhanced imaging and IVIM diffusion-weighted imaging with 16 b-factors (0-1000 s/mm2). Post-RFA liver tumors were segmented into viable tumor, inflammatory reaction, and ablation necrotic regions according to gross and histopathologic examinations. Parameters derived from IVIM were calculated. One-way analysis of variance and least significant difference test were used for comparisons among the three regions. The diagnostic performance of parameters was evaluated using receiver operating characteristic (ROC) analysis. RESULTS: ADCtotal, D, and f values were significantly lower in viable tumor than in inflammatory reaction regions (all P < .05), but D* showed no significant difference between the two regions. ADCtotal values of viable tumor regions were significantly lower than that of ablation necrotic regions (P = .007), but D* values of necrotic regions were significantly lower than that of viable tumor regions (P = .045). In ROC analysis, ADC showed the highest area under the ROC curve for differentiating inflammatory reaction from viable tumor region. CONCLUSIONS: ADCtotal, D, and f were valuable discriminating markers for differentiation between regions of viable tumor and inflammatory reaction in post-RFA tumor, especially ADCtotal outperformed the other two parameters with higher diagnostic performance.

Objective@#To evaluate the feasibility, efficacy and safety of epidermal growth factor receptor-tyrosine kinase inhibitors(EGFR-TKIs) for neoadjuvant therapy.@*Methods@#Eighty-six patients with stage ⅢA EGFR-mutant lung adenocarcinoma were assigned to 2 groups (n=43 in each group) according to the random number table method: neoadjuvant targeted therapy group (single oral dose of erlotinib 150 mg per day, for 9 weeks) and neoadjuvant chemotherapy group (2 cycles of pemetrexed combined with cisplatin chemotherapy followed by 3- week discontinuation). Surgical treatment was underwent after imaging efficacy evaluation.@*Results@#In neoadjuvant targeted therapy group, 4 achieved complete response (CR), 25 achieved partial response (PR), giving an objective response rate (ORR) of 67.4%. In pathological response, 8 patients had grade Ⅰ, 20 patients had grade Ⅱ, giving a pathological response rate of 65.1%. The most frequent adverse events (AEs) were rash and diarrhea. In neoadjuvant chemotherapy group, 2 had CR and 17 had PR, giving an ORR of 44.2%. In pathological response, 3 patients had grade Ⅰ, 15 patients had grade Ⅱ, giving a pathological response rate of 41.9%. The main AEs were hematologic toxic effects. The ORR, histological efficacy and hematologic toxicity showed statistical significance between the two groups (P<0.05). The neoadjuvant targeted therapy group had 90.7% resection rate, (299.8±23.4) ml of hemorrhage volume during operation, (5.2±0.4) days of extubation time and 9.3% postoperative complication rate. Corresponding results were 83.7%, (308.9±22.7) ml, (5.4±0.6) days and 11.6% in neoadjuvant chemotherapy group, which showed no statistical significance (P>0.05).@*Conclusions@#Neoadjuvant targeted treatment for stage ⅢA lung adenocarcinoma harboring EGFR mutations. The regimen could be considered as a choice of neoadjuvant treatment for patients with stage ⅢA EGFR-mutant lung adenocarcinoma.

Effects of proton pump inhibitors on intestinal barrier function in the elderly / 中华老年医学杂志

Objective To explore the effects of regular doses of proton pump inhibitors (PPIs) on intestinal barrier function in the elderly.Methods The elderly hospitalized patients with acidrelated disorders were retrospectively analyzed from April to December 2016 in Department of Geriatrics,the General Hospital of Guangzhou Military Command.Based on the criteria of inclusion and exclusion,all patients received the stomachoscopy examination,and received PPI orally for more than 1 month.The treatment continued for 1-6 months.The blood status was routinely examined at pre-and post-treatment,including the level of liver function,C reactive protein (CPR),procalcitonin (PCT),diamine oxidase (DAO),D-lactate acid and serum endotoxin.Results A total of 88 elderly patients aged 80-96 years were involved.Most patients took PPI for 1 month.The levels of alanine aminotransferase,aspartate amino transferase,CPR and PCT were mostly normal after 1 month of treatment.Meanwhile,there were the comparabilities between the post-and pre-treatment groups in levels of DAO[(6.53±3.00) vs.(6.23±2.42) U/L;t=-0.91,P=0.37],of D-lactate acid[(7.31 ±3.67) vs.(7.62±3.35) mg/L;t=0.73,P=0.47]andof serum endotoxin[(11.69±5.98) vs.(10.97±5.76) U/L;t=-1.66,P=0.10]without statistical significance.Additionally,after 23 patients took PPI for 6 months,there were no statistical significances between the pre-and post-treatment groups in the levels of DAO[(5.35±2.49) vs.(6.59±2.69)U/L,t=1.89,P=0.07],of D-lactate acid[(8.12±3.84) vs.(7.71±3.65) mg/L,t=-0.73,P=0.47]and of serum endotoxin[(10.23 ± 5.51) vs.(10.41±6.45) U/L,t=0.18,P=0.86].Conclusions There is no significant effect on intestinal permeability and intestinal mucosa barrier function in the elderly taking PPI for 6 months.New studies are needed to understand the role of PPI in the intestinal microflora in the elderly.

Intraductal cooling protection technique via PTCD tube versus via ENBD tube in percutaneous microwave ablation for HCC: a comparative study of the protective effect on bile duct thermal damage / 介入放射学杂志

Objective To compare the preventive effect on bile duct thermal damage of percutaneous transhepatic cholangial drainage (PTCD) intubation with that of endoscopic nasobiliary drainage (ENBD)intubation,through which cooling liquid is continuously infused,in treating hepatocellular carcinoma (HCC)located close to the hepatic hilum by using percutaneous microwave ablation (PMWA) therapy.Methods The clinical data of 23 patients with HCC that was located close to the hepatic hilum,who were admitted to authors' hospital during the period from September 2013 to September 2016 to receive PMWA,were retrospectively analyzed.Among the 23 patients,PTCD intubation was employed in 12 and ENBD intubation was adopted in 11,and the cooling tube was placed in the bile duct near the tumor.Through the tube 4℃ cooling saline was rapidly and continuously infused,meanwhile PMWA was carried out under the guidance of B-ultrasound.The occurrence of thermal damage of the bile duct,the cooling technique-related complications,and the recurrence of HCC were compared between PTCD ~oup and ENBD group.Results The mean follow-up time was 20 months (3.0-36.0 months),and no operation-related death occurred in all 23 patients.In each group,postoperative biloma occurred in one patient.No obvious cooling techniquerelated complications were observed in PTCD group,but in ENBD group 4 patients (36.36％) developed cooling technique-related complications,including hemorrhage after incision of duodenal papilla (n=1,9.09％) and acute pancreatitis (n=3,27.27％);the difference in the incidence of cooling technique-related complications between the two groups was statistically significant (P=0.037).No statistically significant differences in local recurrence rate,intrahepatic recurrence rate and mortality existed between the two gro ups(P=1.00,P=0.77 and P=0.61,respectively).Conclusion For the treatment of HCC located close to the hepatic hilum with radical PMWA therapy,continuous infusion of cooling liquid through PTCD intubation or ENBD intubation to prevent the thermal damage of the bile duct is clinically feasible and effective,and PTCD intubation method has less technique-related complications than ENBD intubation method.

Objective To investigate the characteristics of hepatitis virus B ( HBV) reactivation af-ter combined percutaneous microwave ablation ( PMWA ) and transcatheter arterial chemoembolization ( TACE) in patients with hepatocellular carcinoma ( HCC) and to study the therapeutic role of preoperative antiviral therapy .Methods The data on 180 HCC patients who were treated with the combined therapy were analyzed .The antivirus group ( n=90 ) received antiviral therapy , while the control group ( n=90 ) did not.HBV-DNA was used to study the reactivation status of HBV after the combined therapy and the role of antiviral therapy .Results The incidence of HBV reactivation was significantly lower in the antivirus group (8.2%, 7/90) than the control group (20.0%, 18/90, P<0.05).A preoperative HBV-DNA level above 104 copies/ml was the only independent risk factor of HBV reactivation (P<0.05).Conclusions The HBV reactivation rate was relatively high in patients with HBV-related HCC after combined PMWA and TACE.Preoperative antiviral therapy significantly reduced HBV reactivation and thus it should be adminis -trated especially to HCC patients with a preoperative HBV-DNA level above 104 copies/ml.

The clinical features and treatment ofBrucellosis disease in 24 children / 临床儿科杂志

Objective To investigate the clinical features and treatment ofBrucellosis disease in children in recent years.Methods The clinical data of 24 children withBrucellosis disease admitted during January 2011 to December 2015 were retrospectively analyzed.Results In 24 children, 18 was male and 6 was female and average age was 9.8±3.13 years (4-14 years). Twenty-four children were diagnosed withBrucellosis disease by positive tiger red plate agglutination tests and their antibody titer was 1:800-1:100. The children lived mainly in the pastoral areas; four cases (16.67%) had sick family members and cattle and sheep; three cases (12.5%) had histoty of contact only with sick family members; 12 cases (50.00%) had cattle and sheep exposure history; 3 cases (12.5%) had raised cattle or sheep at home in the past 2 years; 2 cases (8.33%) had not have clear transmission route. The onset of the disease occurred year round, with the highest incidence in June and July. The common clinical symptoms were fever, arthralgia, weak, sweat, and anorexia, combined with hepatomegaly and splenomegaly. Patients younger than 8 years old were treated with rifampin and sulfamethoxazole. Patients equal to or older than 8 years old were treated with doxycycline and rifampin. Twenty-three children had been cured after treatment. Only one child stopped taking the drugs 3 weeks after discharge, which resulted in recurrence.Conclusion For children living in pasturing area suffered with unexplained recurrent fever, brucellosis disease should be considered and ruled out.

Objective To investigate the effects of transarterial chemoembolization (TACE)treatment interval on the prognosis of patients with advanced hepatocellular caisinoma(HCC).Methods We retrospectively collected clinical data of 123 advanced HCC patients treated with repeated TACE.The patients were divided into two groups (group A with fixed repeated treatment interval and group B with that according to the clinical needs).Cox regression,survival curve and log-rank test were used to assess the effects of the treat-ment intervals on prognosis.Results The treatment intervals of the group A and group B were (1.1±0.3)months and (3.0±1.5) months,respectively (P <0.001).Multivariate Cox analysis showed the efficacy (P =0.024)and repetition periods (P <0.001 ) were independent prognostic factors.Conclusion TACE interval is independent risk factor for the prognosis of patients with ad-vanced HCC.Repeated TACE treatment according to clinical needs may be more favorable for prognosis of the patients.

A reappraisal of the relationship between metatarsus adductus and hallux valgus / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>A causal link between the metatarsus adductus and hallux valgus is not clear. The aim of this study was to investigate the configurations of the metatarsus adductus deformity by radiological measurements and reappraise the relationship between hallux valgus and metatarsus adductus.</p><p><b>METHODS</b>The first step was evaluation of the relationship between metatarsus adductus and hallux valgus on 143 dorsoplantar weight-bearing radiographs diagnosed as hallux valgus which was also known as bunions. Measurements including the hallux valgus angle (HVA), the intermetatarsal angle (IMA), the Kilmartin angle (KA), the tibial sesamoid position (TSP), and metatarsus adductus angle were taken. The metatarsus adductus angle is defined by Sgarlato's angle (SMA) and Engel's angle (EMA) respectively.</p><p><b>RESULTS</b>The metatarsus adductus angle positively correlates with the HVA (r = 0.590, P = 0.000) and KA (r = 0.601, P = 0.000), yet negatively correlates with the grade of TSP, (r = -0.348, P = 0.000). Contradiction of diagnosis existed in 22 (22/100) subjects diagnosed as metatarsus adductus by SMA yet normal by EMA. In this group, the correlation between HVA and metatarsus adductus angle was negative (r = -0.472, P = 0.027).</p><p><b>CONCLUSIONS</b>EMA and SMA defined metatarsus adductus by different deformity apexes. Metatarsus adductus configurations in that the apex of the deformity lay in either the base of metatarsals or tarsus. They respectively correlate positively or negatively to the HVA.</p>

Percutaneous radiofrequency ablation for the treatment of portal vein tumor thrombus：experience of 15 cases / 介入放射学杂志

Objective To investigate the safety and clinical effect of endovascular radiofrequency ablation (RFA) catheter, the HabibTM VesOpen, in treating portal vein tumor thrombus. Methods Fifteen patients of hepatocellular carcinoma associated with portal vein thrombus causing obstruction of blood flow were enrolled in this study. Guided by ultrasound percutaneous portal catheter implantation was performed, then, under DSA guidance RFA catheter was placed at portal vein tumor thrombus. RF generator (RITA) was connected to the electrodes, the power was set at 10 W for 2 - 10 minutes. The technical success rate, the postoperative complications, the hepatic and renal functions as well as routine blood tests, portal vein blood flow and the ablation extent of portal vein tumor thrombus were evaluated, and the results were analyzed. Results The procedure was successfully accomplished in all patients. No technique-related complications, such as hemorrhage, vessel perforation, bile leak complicated by infection, liver abscess, abdominal bleeding occurred. Direct portography performed immediately after RFA showed that the portal vein was re-opened. Laboratory examinations performed 4 weeks after RFA showed that no obvious changes in hepatic functions and routine blood tests were observed. Doppler ultrasound examinations revealed that flowing blood was obviously displayed within previously obstructed portal vein. CT scanning was carried out in some patients with portal vein thrombus, and it indicated that the portal vein tumor thrombus was reduced in size or even disappeared. Conclusion For the treatment of portal vein tumor thrombus in patients with hepatocellular carcinoma, endovascular radiofrequency ablation is technically feasible, and the initial results indicate that this technique is an effective treatment.

The effect of lateral malleolar malrotational deformity on ankle stability-a study of 3D CT reconstruction / 中华骨科杂志

Objective To evaluate the ankle stability on lateral malleolar rotational models based on three-dimensonal CT reconstruction and volume rendering technique.Methods Eighteen cadaveric specimens were utilized in the study (male 11;female 7; 68.2 years in average) and were divided into 2 groups in which the first group only cut the anterior tibiofibular ligament and defined as intact deltoid ligament group.Another group additionally cut the deltoid ligament and defined as deltoid ligament injured group.Fibular transverse osteotomy was performed at 3 cm proximal to the ankle joint and lateral malleolar rotational malunion model of 5°,10°,15° and 30° were built in every specimen.CT scanning was performed for each model then and all CT data were imported into Mimics 10.01 software.The structures of distal syndesmosis,ankle mortise as well as talus in the mortise were outlined by automatic dense identifying and manually modified later.Three-Dimensional models of these structures and their volume were outputted in the software.The volume of ankle clear space was calculated as the difference value of ankle mortise and talus in the mortise.Ankle stability was reflected by comparison of these volumes to the normal condition.Results With the rising of malrotational degree,the volume of inferior syndesmosis and mortise were increased and the volume of talus in the mortise was reduced.In the deltoid ligament intact group,10° of malrotation would significantly enlarged the volume of distal syndesmosis and ankle clear space when compared to normal condition.However,in the deltoid ligament injured group,5° of rotational deformity would significantly enlarge the volume of ankle clear space and distal syndesmosis.Conclusion The condition of deltoid ligament has significant impact on ankle stability in cases of lateral malrotional deformity.Distal syndesmosis and ankle clear space were significantly enlarged at 10° malrotation deformity.However,additional deltoid ligament injury can significantly reduce ankle stability at just 5° of distal fibular rotational deformity.

Changes of activity of PKC-AchE and HSP70 in tissues of rabbits dying from suspension of anterior limbs / 中国法医学杂志

Objective Investigating activity variance of PKC.AchE and HSP70 in different tissues of rabbits caused by dying from suspension of anterior limbs.in order to study how factors above contribute in the mechanism of death.Methods Suspend rabbit by its anterior limbs until it dies.and coilect tissue from its diaphragmatic muscle,intercostal muscle,myocardium,gastrocnemius,cerebrum,brain stem,liver,kidney and lung.In the control groups,collect same tissues of rabbits dying from strangulation,craniocerebral injury and diseases as contrast.Detect activity of PKC,AchE and HSP70 in tissues of those groups mentioned above by SP stain of immunohistochemistry.and statistically analyze result of detection by rank SUm test of independent samples of multi-groups.Results Compared with data from other control groups,there are more obvious expressions in following tissues of group of suspension:PKC in disphragmatic muscle,intercostal muscles and cerebrum(P＜0.05);AchE in disphragmatic muscles,intercostal muscles,myocardium,cerebrum,liver and nerve tract ofmuscles(P＜0.05);HSP70 in cerebrum,myocardium and lung(P＜0.05).Conclusion Through different mechanisms,PKC,AchE and HSP70 could take some certain contributions in death pmcess of suspension by anterior limbs,and the results above could offer some experimental evidences for related studies and medicolegal investigations.
