ABSTRACT
Objective:To compare the characteristics of corneal stromal demarcation line after different surgical methods of riboflavin/ultraviolet A corneal collagen cross-linking (CXL) in early keratoconus, and analyze the influence of the demarcation line on the cross-linking effect.Methods:A non-randomized controlled clinical study was conducted.Sixty-nine eyes of 69 patients treated with riboflavin/ultraviolet A CXL in the Eye Hospital of Shandong First Medical University from May 2019 to February 2021 were included.According to the cross-linking methods, the patients were divided into epithelium-on treatment group (21 eyes) and epithelium-off treatment group (48 eyes). There were 25 eyes in 5.4 J energy group and 44 eyes in 7.2 J energy group.The morphology and changes of corneal stromal cross-linking reaction (corneal stromal demarcation line) were observed at 2 weeks, 1, 3 and 4 months after operation.Changes in the thinnest corneal thickness (TCT), uncorrected visual acuity (UCVA, LogMAR), best corrected visual acuity (BCVA, LogMAR) and corneal maximum curvature (Kmax) were recorded.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Eye Hospital of Shandong First Medical University (No.2019.05). Written informed consent was obtained from each subject.Results:Of the 69 eyes after operation, 44 eyes (63.77%) had demarcation lines, and 25 eyes (36.23%) had no demarcation lines.The occurrence rate of demarcation lines in the epithelium-on treatment group was 79.17%(38/48), which was significantly higher than 28.57%(6/21) in the epithelium-off treatment group ( χ2=16.186, P<0.01). The occurrence rate of demarcation line in 5.4 J energy group was 72.00%(18/25), and the 7.2 J energy group was 56.80%(25/44), with no significant difference ( χ2=1.565, P=0.302). Slit lamp microscopy and anterior segment-optical coherence tomography showed that the demarcation line appeared at 1-2 weeks after operation, gradually converged and strengthened after 1 month, turned diffuse, blurred and faded by degrees after 2-3 months, and basically disappeared after 4 months.The depth of the demarcation line reached 141-423 μm, with an average depth of (263.44±84.22)μm.Scanning laser confocal microscopy showed that corneal stromal cells were activated and light reflection was enhanced after CXL.Collagen fibers extended vertically and horizontally, crisscrossed, and were in a reticular arrangement.The TCT decreased from preoperative (458.69±38.28)μm to (443.86±36.54)μm at 4 months after operation, showing a statistically significant difference ( t=6.705, P<0.001). There was no significant difference in the TCT reduction between groups with and without demarcation lines ( t=1.684, P=0.100). At 4 months postoperatively, the UCVA of all eyes increased from preoperative 0.74±0.37 to 0.69±0.38, and the difference was statistically significant ( t=2.109, P=0.039). There was no significant difference in BCVA between before and after operation ( t=1.006, P=0.319). There was no significant difference in change of UCVA and BCVA between groups with and without demarcation lines ( t=0.065, P=0.949; t=0.346, P=0.730). There was no significant difference in Kmax in all patients between before and after operation ( t=0.050, P=0.950). There was no significant difference in the Kmax change between groups with and without demarcation lines ( t=-0.739, P=0.464). The change in TCT in the epithelium-off treatment group was significantly greater than that in the epithelium-on treatment group ( t=2.815, P=0.008). There was no significant difference in UCVA, BCVA and Kmax changes between epithelium-on and epithelium-off treatment groups (all at P>0.05). There was no obvious corneal scarring, infectious keratitis, corneal endothelial decompensation or other complications. Conclusions:The demarcation line after CXL may be a sign of the depth of cross-linking reaction, which is more prone to occur after the epithelium-off operation method.Both the epithelium-on and epithelium-off operation methods have similar therapeutic effects.Demarcation line after different cross-linking methods has no significant influence on the cross-linking effect in keratoconus.
ABSTRACT
Objective:To explore the effects of goals-activity-motor enrichment(GAME) therapy on the function of gross and fine motion in infants at high risk of cerebral palsy.Methods:Prospective study.A total of 116 children at high risk of cerebral palsy who met the inclusion criteria and were admitted to the Rehabilitation Department of Qingdao Women and Children′s Hospital from November 2017 to November 2019 were selected in a randomized, single-blind, controlled trial, and randomly divided into control group (58 cases) and observation group (58 cases) according to the random number table method.The two groups were then divided into mild group, moderate group and severe group according to the gross motor quotient(GMQ) of Peabody Motor Development Scale-2 (PDMS-2). During treatment, 4 cases of shedding occurred in the control group and 8 cases in the observation group, respectively.Finally, 54 cases were included in the control group and 50 cases in the observation group.The control group was given regular early intervention rehabilitation, whereas the observation group was given GAME treatment.The Gross Motor Function Measure-88 (GMFM-88), the GMQ of PDMS-2 and the fine motor quotient (FMQ) of PDMS-2 were used to assess the motor function of children before intervention and after 12 weeks of treatment.The Chi- square test or Fisher′ s exact test was used to compare gender-specific data, while the t-test was used to compare age-specific data and rehabilitation evaluation indices. Results:The GMFM-88 scores, GMQ, and FMQ of children in both groups improved significantly after treatment, and the difference was statistically significant [control group GMFM-88: (63.52±10.06) scores vs.(47.02±8.19) scores, t=-19.770, GMQ: 83.02±15.52 vs.73.56±14.72, t=-18.180, FMQ: 81.19±14.88 vs.71.22±13.92, t=-18.413, all P<0.05; observation group GMFM-88: (68.06±10.82) scores vs.(46.16±8.73) scores, t=-32.856, GMQ: 89.98±18.10 vs.72.94±13.84, t=-17.089, FMQ: 88.34±18.08 vs.72.26±13.74, t=-15.370, all P<0.05], and the GMFM-88, GMQ, and FMQ scores of the observation group were significantly higher than those of the control group after treatment, with statistically significant differences(GMFM-88: t=-2.176, GMQ: t=-2.111, FMQ: t=-2.210, all P<0.05). In the observation group, the added value score and quotient of mild group and moderate group were significantly increased compared with that of severe group, and the differences were statistically significant [GMFM-88 added value: the mild group (24.11±3.36) scores and moderate group (22.91±3.46) scores were compared with the severe group (15.70±4.08) scores, t=5.881, 5.164, all P<0.05, GMQ added value: the mild group (19.61±6.83) and moderate group (18.27±6.61) were compared with the severe group (9.80±4.29), t=4.098, 3.915, all P<0.05, the added value of FMQ: mild group (18.72±7.11) and moderate group (17.36±6.10) were compared with severe group (8.50±5.82), t=3.873, 3.863, all P<0.05]. Conclusions:GAME treatment is more effective than early rehabilitation training at improving gross and fine motor function in infants at high risk of cerebral palsy.Its benefits on mild and moderate infants at high risk of cerebral palsy are superior.
ABSTRACT
Objective:To explore any effect of the single- and dual-task treadmill training on the functioning of children with bilateral spastic cerebral palsy.Methods:Fifty children with bilateral spastic cerebral palsy were randomly divided into a single-task treadmill training group (the control group, n=25) and a dual-task treadmill training group (the observation group, n=25). All of the children also received routine rehabilitation training, and the control and observation groups also conducted single- and dual-task treadmill training in addition to the routine rehabilitation training, respectively. Before and after 2 months of treatment, each child′s gross motor functioning was quantified using sections D (standing) and E (walking, running and jumping) of the Gross Motor Function Measurement-88 (GMFM-88) instrument. Balance was quantified using the Pediatric Balance Scale (PBS) and walking mobility was quantified using a 1 minute walking test (1MWT). Modified and dual task Timed Up and Go (mTUG) tests and dual-task effects (DTE) tests were also administered. Results:There were no significant differences in average test scores between the two groups before the treatment. After the treatment significant improvement was observed in both groups. There was no significant difference between the two groups in terms of average GMFM-88, PBS and 1MWT scores, but significantly greater improvement was observed in the average dual-task mTUG and DTE results of the observation group.Conclusion:Both single- and dual-task treadmill training are effective supplements to routine rehabilitation training for children with bilateral spastic cerebral palsy. Dual-task treadmill training is more effective than the single-task version.
ABSTRACT
Objective:To evaluate the effect of individualized blood pressure management on postoperative delirium in elderly hypertensive patients undergoing radical resection for gastrointestinal tumor.Methods:One hundred and sixty elderly hypertensive patients of both sexes, aged 60-80 yr, with body mass index of 19-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective radical resection for gastrointestinal tumor under general anesthesia, were divided into 2 groups ( n=80 each) using a random number table method: standardized blood pressure management group (group S) and individualized blood pressure management group (group I). Combined intravenous-inhalational anesthesia was performed, and BIS values were maintained at 40-60 and heart rate at 50-100 times/min during surgery in both groups. In group S, intraoperative systolic blood pressure was maintained above 90 mmHg with a decrease of less than 30% of the baseline value, while intraoperative fluctuation of systolic blood pressure was maintained less than 10% of the baseline value in group I. The use of vasoactive agents, numerical rating scale scores within 3 days after operation, and length of hospital stay were recorded. Postoperative delirium was evaluated by Confusion Assessment Method within 5 days after surgery. Results:Compared with group S, the intraoperative usage rate of norepinephrine was significantly increased, the incidence of postoperative delirium was reduced( P<0.05), and no significant change was found in the numerical rating scale scores and length of hospital stay in group I ( P>0.05). Conclusions:Individualized blood pressure management can reduce the development of postoperative delirium in elderly hypertensive patients undergoing radical resection for gastrointestinal tumor.
ABSTRACT
Objective:To investigate the gross motor function, manual ability and language communication of children with cerebral palsy (CP) and their correlation.Methods:A total of 318 children with CP (132 with spastic diplegia, 27 with spastic quadriplegia, 32 with spastic hemiplegia, 54 with dyskinesia, 41 with ataxia and 32 children with multiple difficulties) aged 4 to 12 years were classified according to the Gross Motor Function Classification System (GMFCS), the Manual Ability Classification System (MACS), and the Communication Function Classification System (CFCS). Spearman correlation coefficients were used to analyze the correlation among the three ratings.Results:Only 125 of the 318 children (39%) had the same classification level according to all three scales, showing moderate correlation and different levels for patients with different types of disability. The GMFCS and MACS levels of the subjects with spastic quadriplegia and those with dyskinesia were highly correlated. The GMFCS and CFCS levels of the hemiplegic children and those with spastic quadriplegia were also highly correlated. The MACS and CFCS levels were strongly correlated for children with spastic quadriplegia and multiple disabilities.Conclusions:The functioning of children with CP differs with their CP subtype. Correlations among the three functional assessments also differ for children with different subtypes. Combining the three classification systems provides a more comprehensive picture of the children′s ability to function in daily life.
ABSTRACT
Dihydroflavanol-4-reductase (Dfr) is a key enzyme that regulates the synthesis of anthocyanin and proanthocyanidin in the flavonoid biosynthesis pathway. To investigate the difference of dfr gene in Scutellaria baicalensis Georgi with different colors in the same ecological environment, three complete full-length sequences of dfr gene were cloned from the cDNA of S. baicalensis with white, purple-red and purple colors using homologous cloning and RACE techniques. The three genes were named Sbdfr1, Sbdfr2 and Sbdfr3, respectively, and their corresponding structures were analyzed. The results showed that all three Dfr proteins have highly conserved NADPH binding sites and substrate-specific binding sites. Phylogenetic analysis showed that they are closely related to that of the known S. viscidula (ACV49882.1). Analysis of key structural domains and 3D models revealed differences in the catalytically active regions on the surface of all three Dfr proteins, and their unique structural characteristics may provide favorable conditions for studying the substrate specificity of different Dfr proteins. qRT-PCR analysis shows that dfr was expressed at different level in all tissues except the roots of S. baicalensis in full-bloom. During floral development, the expression level of dfr in white and purple-flowered Scutellaria showed an overall upward trend. In purple-red-flowered Scutellaria, the expression first slowly increased, followed by a decrease, and then rapidly increased to the maximum. This research provides a theoretical basis for further exploring the mechanism and function of Dfr substrate selectivity, and are of great scientific value for elucidating the molecular mechanism of floral color variation in S. baicalensis.

ABSTRACT
With the deeper understanding of the pathophysiology and pathogenesis of non-small cell lung cancer (NSCLC) which threatens human health, NSCLC treatment has entered a new era. Transition from traditional treatment based on surgery, radiotherapy and chemotherapy to individualized and precise targeted therapy and safer and more effective immunotherapy. Immune checkpoint inhibitor therapy has been approved as a first-line or second-line treatment for advanced NSCLC, and has achieved extraordinary clinical results. Meanwhile, other types of immunotherapy are rarely explored in NSCLC. Chimeric antigen receptor modified T cells (CAR-T cells) perform well in treating several hematological malignancies. However, it is not ideal for treating patients with solid tumors including NSCLC. This review aims to systematically explain the latest progress of CAR-T in the treatment of NSCLC, mainly including: CAR molecular target selection, CAR-T function enhancement and related toxicity management, as well as the difficulties and prospects of CAR-T treatment of NSCLC. It aims to open up new perspectives and unique ideas for the immunotherapy of NSCLC, and contribute to the building of tumor immunotherapy. .
ABSTRACT
Objective:To explore the effect of goals-activity-motor enrichment (GAME) intervention on the motor function of infants with a mild or moderate developmental disorder.Methods:Randomized, single-blind, controlled trials were applied. Totally 108 infants with mild-to-moderate developmental delay, aged 0 to 12 months, were randomly divided into an observation group and a control group, each of 54. Both groups were further divided into two subgroups, a less-than-6-month-old subgroup and a not-less-than-6-month-old subgroup. All of the children received 30 minutes of routine rehabilitation training five days a week and a 60-minute family intervention every day. In addition, the control group was given traditional neuro-developmental treatment (NDT) while the observation group was provided with an intervention based on the GAME program. Before and after 8 weeks of treatment, both groups were evaluated using the Alberta infant motor scale (AMIS).Results:After the intervention, both groups′ average total scores and average scores in the different positions were significantly better than before the intervention. The average AIMS scores of the observation group supine, prone and seated, as well as their average total score were significantly higher than those of the control group after the intervention. There were no significant differences in the AIMS score increases in the different positions between the two subgroups. However, the increase in average total AIMS score of the less-than-6-month-old subgroup was significantly greater than that of the older subgroup.Conclusion:The GAME protocol can improve the motor function of infants with mild to moderate developmental disorders more effectively than a traditional NDT program. The effect is greater with younger infants.
ABSTRACT
Objective @#To assess the health risks of polycyclic aromatic hydrocarbons（PAHs）exposed through cereal,fried and grilled foods in Hangzhou.@*Methods @#A cross-sectional study was conducted to collect food consumption data of three inconsecutive days among 1 769 subjects selected by probability proportional to size sampling method from two districts in Hangzhou.Fifty samples of fried and grilled food and twenty samples of cereal were collected from five districts in Hangzhou. They were tested for B（a）P,PAH2,PAH4 and PAH8 by high performance liquid chromatography coupled with triple quadrupole gas chromatography-tandem mass spectrometry. The probabilistic models were established for the evaluation of PAHs exposure by @risk software and then margin of exposure（MOE）was calculated.@*Results @#The contents of B（a）P in one sample of fried and grilled food exceeded the limit. The median contents of PAHs ranged from 0.20 to 3.64 μg/kg. The median exposures of B（a）P,PAH2 and PAH4 from both two kinds of foods were 1.54,3.54 and 8.13 ng/（kgbw·d）in the mixed model,1.61,3.76 and 8.09 ng/（kgbw·d）in the non-parameter model. The MOEs of≤95% PAHs exposure level in one kind of food or ≤90% PAHs exposure level in both kinds of foods were more than 10 000. The MOEs of ≥97.5% exposure level of B（a）P,≥95% exposure levels of PAH2 and PAH4 in both kinds of foods in the mixed model,and ≥95% exposure levels of B（a）P,PAH2,PAH4 in both kinds of foods in the non-parameter model were less than 10 000.@*Conclusion @#The health risk of PAHs exposure was very low in more than 90% of the population in Hangzhou. However,for high-end consumers,97.5% or 99% exposure level in one kind of food and 95% exposure level in both kinds of foods had a potential health risk.
ABSTRACT
Objective:To investigate the effect of fluorofenidone on renal interstitial fibrosis in rats with unilateral ureteral obstruction (UUO) and to observe the effect of fluorofenidone on the expressions of collagen type Ⅰ (Col Ⅰ),collagen type Ⅲ (Col Ⅲ),α-smooth muscle actin (α-SMA),connective tissue growth factor (CTGF),platelet derived growth factor (PDGF) in the renal tissues of UUO rats.Methods:Male Sprague-Dawley (SD) rats were randomly divided into a sham-operated group,a UUO group,and a flurofenidone group (n=5).UUO model was induced by ligating the left ureter in rats.The rats were treated with 125 mg/(kg.d) fluorofenidone by gastric gavage in the fluorofenidone group at 24 h before the operation,and the rats were treated with the identical dose of 0.5％ sodium carboxyl methyl cellulose (CMC-Na) in the other 2 groups.The rats were sacrificed at 14 days after UUO.Pathological changes of the renal tissue were observed by HE and Masson staining,the mRNA expressions of Col Ⅰ,Col Ⅲ,α-SMA,PDGF and CTGF were detected by real-time PCR,and the protein expressions of Col Ⅰ,Col Ⅲ,PDGF and CTGF were detected by immunohistochemical staining.Results:The renal interstitial damage index,relative collagen area and mRNA and protein expressions of Col Ⅰ and Col Ⅲ in the renal tissues of the rats in the UUO group significantly increased (P＜0.05),and fluorofenidone could reduce these indexes (P＜0.05).Compared with the sham-operated group,the protein expressions ofα-SMA,PDGF,CTGF and the mRNA expressions of PDGF and CTGF in the renal tissues of the rats in the UUO group were increased,but fluorofenidone could decrease the protein expressions of α-SMA,PDGF,CTGF and the mRNA expressions of PDGF and CTGF (P＜0.05).Conclusion:Fluorofenidone (125 mg/kg·d) could attenuate renal interstitial fibrosis through inhibition offibroblast proliferation,myofibroblastic activation,PDGF and CTGF expression.
ABSTRACT
Objective To compare the clinical features and treatment between elderly onset rheumatoid arthritis(EORA)and young onset rheumatoid arthritis(YORA).Methods The EORA patients (n=60)and the YORA patients (n =90)were compared regarding sex ratio,activity of pathogenetic condition,disease severity,extra-articular manifestations,complications,laboratory indexes,and therapeutic schedules.Results The female/male ratio was 36/24(1.50 ∶ 1.0)in group EORA,and 69/21(3.3 ∶ 1.0)in group YORA,with higher female/male ratio in in group YORA.The frequency of morning stiffness,proximal interphalangeal joint involvement and metacarpophalangeal joint involvement were lower in group EORA(53.3 ％,46.676％ and 61.67 ％) than in group YORA (72.2 ％,77.8 ％,81.11％) (x2 =5.521,15.385,6.960,P =0.018,0.000,0.008 respectively).Large joints involvement at onset of rheumatoid arthritis was higher in group EORA(38.33 ％)than in group YORA(18.89 ％)(x2=6.960,P=0.008).The joint swollen and tender counts were comparatively less (16.51 ± 7.34) and (15.92 ± 8.44) in group EORA than in group YORA(22.46 ± 7.58) and (23.8 ± 8.93) (t =5.080、5.740,all P =0.000) respectively.The accumulated disease activity score(DAS28)was higher in group EORA(5.86± 1.57)than in YORA(4.92± 1.64) (t=3.360,P =0.001).HAQ score was lower in group EORA(0.83 ± 0.85)than in group YORA (1.16±0.91) (t=2.43,P =0.02).Comorbid conditions such as osteoarthritis,osteoporosis,cardiovascular disease and chronic renal insufficiency were more frequent in group EORA (51.7 ％,31.7 ％,18.3 ％ and 15.00％)than in group YORA(27.8％,15.6％,5.6％ and 4.4％)(x2 =11.722,5.445,6.168,5.067,P=0.001,0.020,0.013,0.024).The positive rate of RF were more higher in YORA(70.00％)than in group EORA (48.33％)(x2 =7.126 P=0.008).The synthetic or biologic traditional DMARDs (disease modifying antirheumatic drugs)were widely used in group YORA(78.9％ and 31.1％)than in group EORA(40.0％ and 10.0％)(x2 =14.940,9.153,P =0.000,0.002).The more frequently used program with glucocorticoids hormonal therapy was received in group EORA(38.3 ％)than in group YORA(20.00 ％)(x2 =6.092 P=0.014) Conclusions EORA patients differs from YORA patients in many of ways,including a more balanced gender distribution,atypical presentation at onset of disease,more frequent involvement of large joints,seronegativity in a higher percentage,and less frequent positivity of anti CCP-antibody,which makes diagnosis more difficult in the earlier period.Therapy of EORA with DMARDs should be instituted based on disease activity,if there is no contraindication.
ABSTRACT
Polymeric micelles have exhibited attractive properties as drug carriers, such as high stability in vivo and good biocompatibility, and been successfully used to dissolve various drugs of poor aqueous solubilities. In this study, we developed a new type of polymeric micelles with mannose-mediated targeting and pH-responsive drug release properties for anticancer drug delivery. The polymeric micelles were prepared from an amphiphilic polymer, poly (glycidyl methacrylate)-g-mannose (PGMA-Mannose). An anticancer drug, doxorubicin (DOX), was encapsulated into the micelles during the micellization, and could be released rapidly under acidic condition. The specificity of cellular uptake of the micelles by two different cell lines was studied using confocal laser scanning microscopy and the MTT assay. DOX-loaded micelles were efficiently trapped by mannose-receptor-overexpressing cancer cells MDA-MB-231, whereas mannose- receptor-poor cells HEK293 showed much lower endocytosis towards the micelles under the same conditions. Thus, DOX-loaded micelles displayed higher cytotoxicity to MDA-MB-231 cancer cells as compared with free DOX. The present study demonstrates that PGMA-Mannose micelles are a promising targeted drug delivery system for cancer therapy.

Objective To evaluate the mid-term and long-term effects of early endovascular emboli-zation in treating ruptured posterior communicating artery aneurysm. Methods Early endovascular embolization therapy was carried out in 36 patients with ruptured posterior communicating artery aneurysm (36 aneurysms in total), and the effects of embolization therapy were evaluated by using Raymond grading method. The unified imaging review program was formulated, and the mid-term and long-term effects were evaluated at half, 1, 2, 3 and 5 years after the treatment. Results The technical success rate was 100% in 36 patients (36 aneurysms in total). Raymond grading evaluation showed that gradeⅠwas seen in 32 patients, gradeⅡ in 2 patients, and grade Ⅲ in 2 patients. Recurrence of aneurysm was found in 5 patients (13.89%) at half (n=1), 2 (n=1), 3 (n=1) and 5 years (n=2) after the treatment. Re-rupture of the recurrent aneurysm was seen in one patient (2.78%). No death occurred during the following-up period. Conclusion Early endovascular embolization for ruptured posterior communicating artery aneurysm can effectively improve the prognosis of subarachnoid hemorrhage, and regular imaging examination can promptly detect the recurrence of aneurysm. Effective interventions are helpful for preventing deterioration and rupture of aneurysm.
ABSTRACT
Objective To evaluate the clinical efficacy and safety of transcatheter arterial chemoembolization (TACE) with oxaliplatin (OXA), fluorouracil (5-Fu) and pirarubicin (THP) scheme in treating primary liver cancer. Methods A total of 65 patients with primary liver cancer were treated with TACE using infusion of OXA/5-Fu/THP scheme (TACE group). Other 21 patients with primary liver cancer, who were encountered at the Department of Interventional Radiology of authors’ hospital during the same period as the patients of TACE group, received simple transarterial embolization (TAE group). The therapeutic effect, the occurrence of adverse reactions, the progression-free survival time (PFS) and overall survival time (OS) of the two groups were comprehensively evaluated. The results were compared between the two groups. Results In the TACE group, the objective response rate (ORR) and disease control rate (DCR) were 55.4%and 81.5%respectively, and the median PFS and median OS were 11.5 months and 18.5 months respectively. Single factor analysis indicated that patients, who had liver function of Child-Pugh A and received more times or treatment, and who had small-sized tumor and no portal vein tumor thrombus or metastasis, usually had a better prognosis, and the differences were statistically significant (P<0.05). The prognosis of the patients with Barcelona staging (BCLC) B was better than that of the patients with Barcelona staging C, and the difference was statistically significant (P=0.000). Cox multivariate analysis revealed that the portal vein tumor thrombus and tumor metastasis were independent risk factors for the prognosis of the patients. Compared with the TAE group, TACE with OXA/5-Fu/THP scheme could effectively improve the mean progression-free survival time. Conclusion For the treatment of primary liver cancer, TACE with infusion of OXA/5-Fu/THP is clinically effective with fewer adverse reactions.
ABSTRACT
To investigate the assessed value of serum lactate dehydrogenase (LDH) and vascular endothelial growth factor (VEGF) for short-term efficacy of transcatheter arterial chemoembolization (TACE). Methods: Serum concentrations of LDH and VEGF from 70 patients with primary liver cancer on the 1st day before therapy and the 3rd, 7th, 14th, and 21st day after TACE ther-apy was determined. The benefit group includes complete remission, partial remission, and stable disease, while the invalid group in-cludes only disease progression. Results:The serum levels of LDH and VEGF in the invalid group were significantly higher than those in the benefit group on the 14th and 21st days after TACE (P<0.05). The percentage changes of the serum concentrations of LDH and VEGF in the invalid group were higher than those in the benefit group on the 21st day after TACE. Percentage changes on the 21st day after TACE were drawn into the ROC curve;the areas under the curve were 65.9%and 85.5%. The optimal cutoff points of LDH and VEGF, which correspond to the Youden index, were 0.272 and 0.745, respectively. Conclusion:The expression levels of VEGF and LDH can be used to assess the short-term efficacy of TACE. A lower expression level corresponds to short-term efficacy.
