ABSTRACT

Osteosarcoma is a kind of primary malignant tumor of bone originated from mesenchymal tissue, which mainly occurs in children and adolescents, and presents the characteristics of high malignancy, rapid growth, early metastasis and poor prognosis. Currently, most of the studies at home and abroad mainly focused on therapeutic procedures. However, reliable predictors are essential for monitoring disease changes, guiding treatment and evaluating prognosis. In recent years, the research on prognosis related genes of osteosarcoma has become a new hotspot. Its abnormal expression affects the progress, invasion and metastasis of osteosarcoma cells, and plays an important role in drug resistance and chemotherapy of osteosarcoma. This paper briefly summarizes the abnormal expression of genes related to the prognosis of osteosarcoma: miRNAs, Incrna, CircRNA, ErbB gene family and the imbalance of oncogenes and immune related genes, and fully understands their characteristics, in order to provide a new direction and possible new drug treatment target for the early diagnosis and treatment of osteosarcoma patients, so as to improve the prognosis of osteosarcoma patients.

ABSTRACT

LIN28 is an RNA binding protein with important roles in early embryo development, stem cell differentiation/reprogramming, tumorigenesis and metabolism. Previous studies have focused mainly on its role in the cytosol where it interacts with Let-7 microRNA precursors or mRNAs, and few have addressed LIN28's role within the nucleus. Here, we show that LIN28 displays dynamic temporal and spatial expression during murine embryo development. Maternal LIN28 expression drops upon exit from the 2-cell stage, and zygotic LIN28 protein is induced at the forming nucleolus during 4-cell to blastocyst stage development, to become dominantly expressed in the cytosol after implantation. In cultured pluripotent stem cells (PSCs), loss of LIN28 led to nucleolar stress and activation of a 2-cell/4-cell-like transcriptional program characterized by the expression of endogenous retrovirus genes. Mechanistically, LIN28 binds to small nucleolar RNAs and rRNA to maintain nucleolar integrity, and its loss leads to nucleolar phase separation defects, ribosomal stress and activation of P53 which in turn binds to and activates 2C transcription factor Dux. LIN28 also resides in a complex containing the nucleolar factor Nucleolin (NCL) and the transcriptional repressor TRIM28, and LIN28 loss leads to reduced occupancy of the NCL/TRIM28 complex on the Dux and rDNA loci, and thus de-repressed Dux and reduced rRNA expression. Lin28 knockout cells with nucleolar stress are more likely to assume a slowly cycling, translationally inert and anabolically inactive state, which is a part of previously unappreciated 2C-like transcriptional program. These findings elucidate novel roles for nucleolar LIN28 in PSCs, and a new mechanism linking 2C program and nucleolar functions in PSCs and early embryo development.

ABSTRACT

Objective:To evaluate the feasibility, safety and efficacy of the magnetic resonance imaging guided focused ultrasound surgery (MRgFUS) in the treatment of localized prostate cancer (PCa).Methods:The data of 5 patients treated by MRgFUS from August 2020 to June 2021 in our institution were retrospectively analyzed. The median age was 73 (58-80) years, with the median PSA of 7.34 (5.19-8.40) ng/ml, and a median prostate volume of 27.96 (21.50-37.91) ml. The median pretreatment international prostate symptom score (IPSS) was 13(0-18). Of the 3 patients with intention of erectile function preservation, the pretreatment international index of erectile function-15 (IIEF-15) score was 12, 23 and 3, respectively. All patients had histopathology-proven PCa of grade group ≤ International Society of Urological Pathology (ISUP) 3, pre-operative PSA level <20 ng/ml, and a clinical stage ≤T 2b. A total of 6 lesions was confirmed by biopsy, with 3 of ISUP grade group 3 and 3 of ISUP grade group 1. All 5 patients underwent MRgFUS which was guided by a real-time magnetic resonance imaging (MRI). PSA, MRI and repeated biopsy were conducted to monitor recurrence. Questionnaires consisted of IPSS, IIEF-15, and the International Consultation on Incontinence-questionnaire-Short Form (ICI-Q-SF) were recorded before and after MRgFUS to evaluate the impact on functional preservation. Results:A total of 5 patients received MRgFUS. In total, 5 of the 6 lesions were treated. 1 lesion unvisible on MRI was not clinically significant and was left untreated. The median time in MRI scanner was 190 (140-355) min, and the median sonication time was 64 (35-148) min with the median sonications of 8 (5-13). The median catheter indwelling time was 1 (1-8) days. No other adverse effects were reported. The PSA level of all 5 patients decreased, with the nadir PSA of 1.196 ng/ml, 4.398 ng/ml, 4.135 ng/ml, 1.562ng/ml and 1.350ng/ml, respectively. 4 of the patients had a PSA decrease over 50%. No PCa lesion was seen on MRI at 3-month follow-up visit. As for functional preservation, the post-MRgFUS IPSS declined compared with the baseline score, and the IPSS of last follow-up was 5(0-14). Of the 3 patients with intention to preserve the erectile function, the erectile function score of IIEF-15 were 12, 30 and 9 three months after the treatment, respectively. No incontinence occurred postoperatively.Conclusions:MRgFUS is a feasible and safe way for the treatment of low- to intermediate-risk localized PCa, with satisfactory performance on functional preservation and low incidence of complications. The oncological outcomes still need to be establised with longer follow-up time and larger sample studies.

ABSTRACT

Objective:To analyze the prognosis of patients with positive resection margin after radical prostatectomy, as well as the prostate-specific antigen (PSA)level and risk factors for PSA progression.Methods:A retrospective analysis was performed on the data of 141 patients with pathologically diagnosed prostate cancer who underwent RP from May 2012 to August 2020 in Beijing Hospital. The mean age was (67.4±6.7)years, the preoperative median PSA was 9.6 (1.4-152.8) ng/ ml and the median follow-up time was 56 months. Postoperative pathology was T 2 stage 74 (52.5%), T 3 stage 63 (44.7%), T 4 stage 4 (2.8%). Biochemical recurrence after radical resection was defined as PSA rose to more than 0.2 ng/ml and showed an upward trend after two consecutive follow-ups. In this study, serum PSA ≥ 0.1 ng/ml without biochemical recurrence after radical operation was defined as PSA progression. The PSA level, risk factors of PSA progression and prognosis of patients with positive resection margin were analyzed. Univariate and multivariate Cox regression analysis was used to analyze the correlation between age, preoperative PSA level, pathological stage (pT), ISUP classification, surgical approach, lymph node dissection, single/multiple positive margins and PSA progression. Results:The median follow-up of 141 patients was 52 months(1-104 months). There were 69 (48.9%) patients in the PSA progression group and 72 (51.1%) patients in the non PSA progression group. In the PSA progression group, 13 (18.8%) patients did not receive treatment and 8 (61.5%) patients had biochemical recurrence. 4 (5.8%) patients received radiotherapy alone, and 2 (50.0%) patients had biochemical recurrence. 52 (75.4%) patients received endocrine therapy or endocrine therapy combined with radiotherapy, and 5 (9.6%) patients developed castration resistance. Multivariate Cox regression analysis showed preoperative PSA ( HR=1.015, 95% CI 1.005-1.025, P =0.004), ISUP grade and group ( HR=1.351, 95% CI 1.091-1.673, P =0.006), surgical method ( HR=2.233, 95% CI 1.141-4.370, P =0.019) was correlated with PSA progression. Conclusions:The incidence of surgical positive margin is high after RP. Nearly half of the patients with surgical positive margin developed a PSA progression status. Preoperative PSA, ISUP grade group, and the surgical approach are risk factors for PSA progression in patients with positive surgical margins. Patients with these risk factors should be monitored more closely and treated more aggressively.

ABSTRACT

Objective:To assess the efficacy and safety of 100 units of botulinum toxin A (BTX-A) intradetrusor injection in patients with overactive bladder.Methods:From April 2016 to December 2018, 17 tertiary hospitals were selected to participate in this prospective, multicenter, randomized, double-blind, placebo-controlled study. Two phases of study were conducted: the primary phase and the extended phase. This study enrolled patients aged 18 to 75 years who had been inadequately managed by anticholinergic therapy (insufficient efficacy or intolerable side effects) and had spontaneous voiding with overactive bladder. Exclusion criteria included patients with severe cardiac, renal and hepatic disorders, patients with previous botulinum toxin treatment for 6 months or allergic to BTX-A, patients with urinary tract infections, patients with urinary stones, urinary tract tumors, diabetes mellitus, and bleeding tendency. Eligible patients were randomly assigned to BTX-A group and placebo control group in a ratio of 2∶1. Two groups of patients received 20 intradetrusor injections of BTX-A 100U or placebo at the depth of the submucosal muscle layer respectively under cystoscope, including 5 injections at the base of the bladder, 3 injections to the bladder triangle, 5 injections each to the left and right walls and 2 injections to the top, sparing the bladder neck. As a placebo control group, patients received same volume of placebo containing no BTX-A and only adjuvant freeze-dried preparations for injection with the same method. A combination of gelatin, sucrose, and dextran served as adjuvants. Average micturition times per 24 hours, urinary incontinence (UI) episodes per day, average micturition volume per day, OAB symptom score(OABSS), and quality of life (QOL) score were recorded at baseline and the 2nd, 6th and 12th week after treatment. The primary efficacy endpoint was the change from baseline in the average micturition times per 24 hours at the 6th week after treatment. The secondary efficacy endpoints included the change from baseline in the average micturition times per 24 hours at 2nd and 12th week, as well as the change from baseline in the OABSS, QOL score, average frequency of urgency and UI episodes per day, urgency score, average micturition volume per day at 2nd, 6th and 12th week after treatment. Patients were followed for 12 weeks to assess adverse events (AEs). After assessed at week 12, if the micturition times has decreased less than 50% compared to baseline and the patient is willing to receive retreatment, then patients could enter the extended trial phase. In that phase, patients in both groups were injected with 100 units BTX-A from 12th week onwards and then followed up the same indicators for 12 weeks.Results:216 patients were enrolled in this trial (144 cases in the BTX-A group and 72 cases in the placebo control group). Baseline characteristics such as age (47.75±14.20 in the BTX-A group and 46.39±15.55 in the control group), sex (25 male/117 female in the BTX-A group and 10/61 in the control group), and disease duration (0.51 years in the BTX-A group and 0.60 years in the control group) were balanced between the two groups( P>0.05). A marked reduction from baseline in average micturition times per 24 hours was observed in all treatment groups at the 6th week and the reduction of the two groups was statistically different ( P<0.001 and P=0.008 respectively). Compared with the baseline, the average micturition times per 24 hours at the 6th week decreased from baseline by 2.40(0.70, 4.60)times for the BTX-A group and 0.70(-1.00, 3.30) times for the placebo control group respectively, and the difference between the two groups was considered to be statistically significant ( P=0.003). The change rates of average micturition times per 24 hours from baseline at the 6th week of the two groups were (16±22)% and (8±25)% respectively, and the difference between the two groups was statistically significant ( P=0.014). Compared with the baseline, the average micturition times per 24 hours at 2nd and 12th week decreased by 2.00(0.00, 4.00)and 3.30(0.60, 5.03)for the BTX-A group, 1.00(-1.00, 3.00)and 1.70(-1.45, 3.85)for the placebo control group respectively. The difference between two groups was considered to be statistically significant ( P=0.038 and P=0.012); the changes of average urgency times per day for the BTX-A group and the control group at the 2nd, 6th and 12th week were 2.00(0.00, 4.30)and 2.40(0.30, 5.00), 3.00(0.30, 5.70)and 0.70(-1.30, 2.70), 0.70(-1.30, 3.00) and 1.35(-1.15, 3.50), respectively. There were significant differences between two groups at the 2nd, 6th and 12th week, ( P=0.010, P=0.003 and P=0.025, respectively). The OABSS of the BTX-A group and the control group at the 6th week decreased by 1.00(0.00, 4.00)and 0.50(-1.00, 2.00) compared with the baseline, and the difference between the two groups was statistically significant ( P=0.003). 47 cases of BTX-A group and 34 cases of placebo control group entered the extended trial phase, and 40 and 28 cases completed the extended trial phase, respectively. The average micturition volume per 24 hours changed by -16.60(-41.60, -0.60)ml and -6.40(-22.40, 13.30)ml, (-35.67±54.41)ml and(-1.76±48.69)ml, (-36.14±41.51)ml and (-9.28±44.59)ml, (-35.85±43.35)ml and(-10.41±40.29)ml for two groups at the 12th, 14th, 18th and 24th week, and the difference between two groups was statistically significant at each follow-up time ( P=0.01, 0.006, 0.012 and 0.016, respectively). There was no significant difference in other parameters( P>0.05). However, adverse reactions after intradetrusor injection included increased residual urine volume (27 in the BTX-A group and 3 in the control group), dysuria (21 in the BTX-A group and 6 in the control group), urinary infection (19 in the BTX-A group and 6 in the control group), bladder neck obstruction (3 in the BTX-A group and 0 in the control group), hematuria (3 in the BTX-A group and 1 in the control group), elevated alanine aminotransferase (3 in the BTX-A group and 0 in the control group), etc. During the follow-up period, there was no significant difference in the other adverse events between two groups except the increase of residual urine volume( P<0.05). In the primary trial phase, among the 27 cases with increased residual urine volume in BTA group, only 1 case (3.70%) with PVR more than 300 ml; the PVR of 3 patients in the placebo group was less than 100 ml. The increase of residual urine volume caused by the injection could be improved or disappeared with the passage of time. Conclusions:Intradetrusor injection of Chinese BTX-A improved the average micturition times per 24 hours, the average daily urgent micturition times, OABSS, and average micturition volume per time, and reduced the adverse effects in patients with overactive bladder.Chinese BTX-A at dose of 100U demonstrated durable efficacy and safety in the management of overactive bladder.

ABSTRACT

Objective To analyze the biomechanical characteristics of lumbar fusion by 3 internal fixation methods using three-dimensional (3D) finite element (FE) method. Methods The FE fixation models of physiological L4-5, unfixed fusion L4-5, translaminar facet screw (TLFS), lumbar pedical screw+translaminar facet screw (LPS+TLFS), bilateral pedical screw (BPS) with complete osteotomy or partial osteotomy of facet joint were established, respectively. The biomechanical characteristics of L4 centrum and implants under six motion states (spinal flexion, extension, lateral bending and axial rotation) in L4-5 fusion model and three fixation models were compared by FE analysis. Results The average maximal displacements of L4 centrum in L4-5 unfixed fusion model, TLFS model, TLFS+LPS model, BPS model were 1.410 8, 0.629 8, 0.336 9, 0.252 8 mm (complete osteotomy of facet joint) and 1.296 7, 0.844 9, 0.340 9, 0.273 8 mm (partial osteotomy of facet joint); the average maximal displacements of cage were 0.479 9, 0.319 5, 0.167 6, 0.126 4 mm (complete osteotomy of facet joint) and 0.378 7, 0.348 4, 0.183 5, 0.137 2 mm (partial osteotomy of facet joint);the average maximum stresses of screws and rods during 6 motions in TLFS model, TLFS+LPS model, BPS model were 178.34, 79.55, 56.33 MPa (complete osteotomy of facet joint) and 142.29, 103.02, 59.69 MPa (partial osteotomy of facet joint). Conclusions In percutaneous transforaminal lumbar interbody fusion, the fixation effect of BPS model was similar to that of LPS+TLFS model. BPS model could achieve the best spinal stability, and LPS+TLFS model was also a good fixation method. The stability of TLFS model alone was relatively poor, but it was still better than that of cage bone graft without internal fixation. In the absence of internal fixation, preservation of the articular process significantly increased stability of the spine.

ABSTRACT

Objective:By comparing the clinical data and follow-up data of patients with coronary heart disease combined with chronic kidney disease who choose different ways of revascularization for the first time when do PCI revascularization therapy again. To investigate the effect of coronary artery bypass grafting on revascularization for the first time in patients.Methods:A retrospective analysis of clinical data of 358 patients with coronary heart disease combined with chronic kidney disease who received revascularization PCI from January 2008 to December 2017 was made. All the patients were divided into CABG group(75 cases) and PCI group(283 cases) for clinical characteristics and prognosis comparison. According to the occurrence of major adverse cardiovascular events, Cox regression was carried out to establish a risk prediction model. Results:Compared with the patients in the two groups, the ratio of current smoking(17.33% vs. 33.57%, P=0.006) and hospitalized patients with recurrent acute myocardial infarction(28.00% vs. 40.64%, P=0.045) were decreased in CABG group, the ratio of triple-vessel disease(82.67% vs. 55.12%, P<0.001) and road via femoral artery(49.33% vs. 24.03%, P<0.001) were significantly increased in the CABG group, the Gensini score[136.00(100.75, 164.00) vs. 53.00(39.00, 74.00), P<0.001] and contrast agent dosage [300(200, 400)ml vs. 200(200, 300)ml, P<0.001] were significantly higher in CABG group, but the incidence of MACCE was significantly lower in CABG group than in PCI group (40.00% vs. 57.60%, χ2=7.571, P=0.0059). According to the Cox regression of MACCE events, it was found that CABG ( RR=0.586, 95% CI: 0.396-0.867, P=0.007) and higher glomerular filtration rate( RR=0.988, 95% CI: 0.980-0.997, P=0.007) were the protective factors, white blood cell elevation( RR=1.100, 95% CI: 1.020-1.187, P=0.013) and the application of renin-angiotensin-aldosterone system inhibitor( RR=1.380, 95% CI: 1.016-1.875, P=0.039) were independent risk factors. Conclusion:Patients with coronary heart disease combined with chronic kidney disease can benefit from CABG for the first time in revascularization, when they were confronted with PCI revascularization again.

ABSTRACT

Objective To investigate the relationship between preoperative urodynamic parameters and the improvement of overactive bladder (OAB)symptoms after GreenLight laser vaporization,and to explore prognostic factors for improvement of OAB symptoms in the elderly.Methods A retrospective study was conducted in 100 benign prostatic hyperplasia (BPH)patients undergoing GreenLight laser vaporization at the Department of Urology of Beijing Hospital from July 2015 to March 2017.All patients completed a preoperative urodynamic examination and received GreenLight laser vaporization.Clinical data including age,prostate-specific antigen (PSA),prostate volume,international prognostic scoring system(IPSS),overactive bladder symptom score (OABSS),quality of life(QOL)and urodynamic parameters were collected.The related factors for improvement of OAB symptoms after GreenLight laser vaporization were analyzed by a binary Logistic regression analysis.Results All patients underwent surgery successfully and completed a 12-month follow-up.Both urinary storage and voiding symptoms improved at 3 and 12 months after GreenLight laser vaporization(P<0.05).The scores of IPSS,IPSS storage (IPSS-S),IPSS voiding (IPSS-V),OABSS and QOL and nighttime voiding frequency decreased and urinary storage and voiding symptoms improved at 3 and 12 months after GreenLight laser vaporization,compared with pre-surgery data(P<0.05).The success rates of storage symptom improvement at 3 and 12 months after GreenLight laser vaporization were 62.0 % (62/100) and 68.0 % (68/100) evaluated by IPSS-S and 68.0 % (68/100) and 75.0% (75/100)by OABSS,respectively.Multiple Logistic regression analysis showed that age,detrusor contractility,residual urine volume and nighttime voiding frequency were independent influencing factors for prognosis(OR =35.714,0.352,0.110 and 0.040,P =0.000,0.027,0.018 and 0.002).Conclusions GreenLight laser vaporization is an effective method in treating BPH with OAB.Age is an independent unfavorable factor and the residual urine volume,nighttime voiding frequency and detrusor contraction are independent influencing factors for prognosis.Enough attention should be paid to these related parameters before surgery.

ABSTRACT

Objective To analyze the biomechanical characteristics of 3 different posterior internal fixation methods for treating thoracolumbar burst fracture by three-dimensional finite element (FE) method. Methods The FE fixation models of normal thoracolumbar, short-segment posterior fixation (SSPF), short-segment posterior fixation with intermediate screws at fractured level (SSPFI) and long-segment posterior fixation (LSPF) were established, respectively. The biomechanical characteristics of L1 centrum and the adjacent intervertebral disc under 6 kinds of motion states (spinal flexion, extension, lateral bending and axial rotation), in normal thoracolumbar model and 3 fixation models were compared by FE analysis. Results L1 centrum equivalent stress distributions in normal thoracolumbar model, SSPF model, SSPFI model, LSPF model were 31.63, 13.41, 110.35, 13.17 MPa, respectively. The maximum equivalent stress of adjacent intervertebral disc in normal thoracolumbar model was 3.84 MPa, which was located in L1-2 intervertebral disc; the maximum equivalent stress of adjacent intervertebral disc in 3 fixation models was 0.41, 0.36, 0.40 MPa, respectively, which was all located in T12-L1 intervertebral disc. Conclusions Fixation in short segment of the fractured vertebrae could lead to an increase of stress in the centrum. The stress of the adjacent intervertebral disc in 3 fixation models was smaller than that in normal spinal model.

ABSTRACT

Objective To study the correlation between the risk factors of coronary slow flow phenomenon ( CSF) and the level of plasma D-dimer in patients with ACS ( acute coronary syndrome) after emergency percutaneous coronary intervention ( PCI) .Methods A total of 297 patients with ACS after PCI were enrolled for retrospective analysis.All patients were divided into CSF group and control group in the light of corrected thrombolysis in myocardial infarction (TIMI) frame count method (cTFC).Multivariate analysis for evaluating clinical predictors of CSF was carried out using Logistic regression test and Pearson analysis to find the correlation between plasma D-dimer and cTFC.The predictive value of D-dimer level in the occurrence of coronary slow flow was determined by using receiver operating characteristic ( POC) curve analysis.Results CSF was observed in 59 cases (19.8%).The plasma D-dimer was significantly higher in the coronary slow flow group compared with the control group ( P <0.05 ) .Multivariate regression analysis and Logistic regression test showed that the level of plasma D-dimer ( OR =1.276, 95%CI:1.132-3.224, P=0.012), thrombus score (OR =1.108, 95%CI: 1.085-2.103, P =0.018) and target lesion length of culprit vessel ( OR =1.436, 95%CI: 0.635-1.382, P =0.037 ) were the risk factors of CSF.Correlation analysis showed that plasma D-dimer were positively associated with CSF. Receiver operating characteristic ( ROC ) curve analysis showed that D-dimer cutoff point at 515.3 ng/ml had a good judgment significance ( AUC 0.783, OR =1.502, 95%CI: 1.324-2.531, P =0.005). Conclusions The increased D-dimer level is a risk factor and plays an important role in the ACS patients with the CSF phenomenon, thereby predicting no-reflow phenomenon after primary PCI in these patients.

ABSTRACT

Volume concentration determination for atmospheric krypton and xenon is very important for krypton-85 and radioactive xenon isotopes monitoring. An injection setup integrated adjustable quantity sample injection and quantitative dilution function was designed. The effects of EI source parameters on the sensitivity of MS detector were studied. The optimized values were as following: ionization energy of 70 eV, emission current of 40 mA, cathode voltage of 27 mV, focus voltage of 85 mV and lens compensation of 20 V, respectively. A GC-MS method for the determination of krypton and xenon in atmosphere without of sample pretreatment was developed. The minimal detected concentrations for krypton and xenon were 3. 3×10-8(V/V) and 2. 6×10-9(V/V). Moreover, the krypton and xenon concentrations in the ground level air around our laboratory were measured with the results of 1 . 1 × 10-6 ( V/V ) and 9 . 3 × 10-8 ( V/V ) . The related combined standard uncertainties for krypton and xenon results were 2. 38% and 3. 15%, respectively.

ABSTRACT

BACKGROUND:A variety of factors contribute to biliary injury that is difficult to be repaired. Stent implantation is extensively used for bile duct injury, but either scaffolds made by metal or plastics can lead to certain adverse reactions. OBJECTIVE:To explore the biological characteristics of a novel biodegradable scaffold and its repair effects on bile duct injury. METHODS:The biological characteristics of the novel biodegradable scaffold were detected by fresh bile, and its degradation was observed at different time points. Thirty Bama mini pigs were included and were randomly divided into observation group (n=15) and control group (n=15). After bile duct injury models were prepared, the control group was subjected to the bile duct interrupted suture, while the observation group was subjected to the novel biodegradable scaffold combined with omentum majus. The biological properties of the scaffolds were observed. Hepatic enzymes and serum total bilirubin levels were detected, as wel as hematoxylin-eosin staining, Masson staining and immunohistochemistry detection ofα-smooth muscle actin were performed. RESULTS AND CONCLUSION:Before and 1, 3 and 6 months after surgery, hepatic enzymes and total bilirubin of two groups were detected, and neither intra-group nor intergroup comparisons had significant differences (P>0.05). Hematoxylin-eosin staining and Masson staining revealed that inflammatory reactions and fiber hyperplasia at the anastomotic site in the observation group were lighter than those in the control group at different time points after surgery. Theα-smooth muscle actin-positive scores in both two groups were in a rise at 1 and 3 months after surgery, and peaked at the 3rd month, and then began to decline. Moreover, theα-smooth muscle actin-positive scores in the observation group were significantly lower than those in the control group at 3 and 6 months after surgery (P<0.05). These results show that the novel biodegradable scaffold has good biological characteristics and can obtain ideal repair effects in the bile duct injury.
