RESUMO
Objective: To evaluate the mid-term efficacy of ABO incompatible living donor kidney transplantation (ABOi-KT) based on the results of routine renal biopsy for transplantation. Methods: Retrospective collection of clinical data from 23 pairs of ABOi-KT donors and recipients at the First Affiliated Hospital of Sun Yat-sen University from July 2015 to November 2021. ABOi-KT was performed on recipients after desensitization treatment, and the results of routine kidney transplant biopsy at 1 week, 1 month, 3 months, 6 months, and 12 months after surgery were analyzed. Combined with blood type antibody levels and renal function recovery, the mid-term efficacy of ABOi-KT was evaluated. Results: Among the 23 recipients, there were 19 males and 4 females; age range from 19 to 47 years old [(29.6±6.7) years old], all underwent ABOi-KT successfully after receiving desensitization treatment. The follow-up time was (44.6±22.4) months, of which 22 cases were followed up for more than 1 year. The incidence rates of rejection reactions at 1 week, 1 month, 3 months, 6 months, and 12 months after surgery were 15.0% (3/20), 11.1% (1/9), 7.7% (1/13), 25.0% (3/12), and 12.5% (1/8), respectively. For receptors with rejection reactions, targeted anti-rejection therapy was performed based on clinical symptoms and various indicators. Borderline T cell mediated rejection (TCMR) can be converted to mild tubular inflammation after anti-rejection treatment. The positive rate of complement C4d in peritubular capillaries was 95.0% (19/20) one week after surgery, and the positive rate of complement C4d was 100% at 3 and 12 months after surgery. The cumulative survival rates at 1, 3, 5, and 7 years after surgery were all 100%. The cumulative survival rates at 1, 3, 5, and 7 years after kidney transplantation were 100%, 93.3%, 84.0%, and 84.0%, respectively. Except for 2 recipients who underwent transplantation in 2017 and experienced kidney failure at 30 and 49 months after surgery, all other transplanted kidneys survived. Conclusions: The results of routine renal transplant biopsy show that ABOi-KT has a good mid-term therapeutic effect. The pathological changes of ABOi-KT can be dynamically observed through routine renal transplant biopsy and targeted treatment for rejection reactions can be provided accordingly.

Objective: To understand the genetic variation of soft tissue sarcomas, and to provide a scientific evidence for the individualized treatment. Methods: The somatic mutation and germline mutation of 45 adult soft tissue sarcomas had been detected by high-throughput sequencing technology, the clinical data were also analyzed. Results: A total of 88 gene mutations were detected in 45 samples, including 78 single nucleotide variation (SNV), 13 insertion/deletion (Indel) and 19 copy number variation (CNV). The most common mutant genes are TP53, CDKN2A, MDM2, CDK4, NF1 and PTEN. Among them, the mutation rates of TP53-MDM2/MDM4-CDKN2A pathway, CDKN2A/CDK4/RB1 pathway, and RAS/NF1/PTEN/PI3K pathway were more frequent (32/88, 36%). In terms of immunotherapy biomarkers among 10 samples, the median value of tumor mutation burden was 2.02 muts/Mb (0-4.24 muts/Mb), and all were microsatellite stable. Conclusions: This study analyzes the genetic variation of soft tissue sarcoma, and determines the high-frequency gene mutations and pathways, which may be the potential drug targets. This finding can provide scientific evidences for the personalized treatment of soft tissue sarcoma.

BACKGROUND AND PURPOSE: Although non-alcoholic fatty liver disease (NAFLD) shares common cardiovascular risk factors with cerebral white matter hyperintensity (WMH), few studies have reported the association between NAFLD and WMH. The association between the presence of NAFLD with its severity and the volume of WMH was investigated. METHODS: This cross-sectional study was conducted for 2460 subjects who voluntarily participated in health screening check-ups including brain magnetic resonance imaging and liver ultrasonography at the Health Promotion Center at Seoul National University Hospital from 2009 to 2013. Ultrasonography was used to detect the presence and severity of NAFLD combined with the NAFLD fibrosis score and the FIB-4 index. The volume of WMH was measured using a semi-automated quantification method by a trained neurologist. RESULTS: The prevalence of NAFLD was 36.5%, and the median volume of WMH in all the subjects was 1.1 ml (interquartile range 0.2-2.7 ml). The presence of NAFLD was associated with a smaller volume of WMH [ß (standard error, SE) -0.051 (0.046); P = 0.012]. Moderate to severe NAFLD was associated with a smaller volume of WMH than was non-NAFLD [ß (SE) -0.067 (0.061); P = 0.002]. The negative correlation observed between NAFLD severity and WMH volume was persistent only in those with low FIB-4 index and low NAFLD fibrosis scores, whereas there was a positive association in those with high FIB-4 index and NAFLD fibrosis scores. CONCLUSIONS: Non-alcoholic fatty liver disease, and its severity, showed a favorable association with WMH volume. However, its causality and mechanism should be evaluated in further relevantly designed studies.

Objective: To evaluate the efficacy and prognostic factors of comprehensive treatment of undifferentiated high grade pleomorphic sarcoma (UHGPS) in extremities and trunk, including surgery, radiotherapy and chemotherapy. Methods: A retrospective analysis and follow-up of 131 UHGPS cases with clinical stage â ¡ or â ¢ in extremities and trunk soft tissue was performed to analyze the prognostic factors. Survival data were collected through follow-up. The survival rate was calculated with life table method and Kaplan-Meier survival curves were drawn. Survival rate between the two groups was compared using Log rank test. The multivariate analysis was performed using Cox regression model. Results: The median survival time of 131 patients was 41.6 months. The 1-year, 3-year and 5-year survival rates were 95.0%, 82.0%, and 77.0%, respectively. The 5-year recurrence-free survival rate was 81.0%, and the 5-year metastasis-free survival rate was 72.0%. Univariate analysis showed that the tumor size, initial or recurrence, surgical margin, AJCC stage, and with/without standard treatment were associated with overall survival (all P<0.05). Stratification analysis according to the American Joint Committee of Cancer (AJCC) stage showed that 5-year survival rate of stage â ¡ patients with radiotherapy was 100.0%, which was higher than that of patients without radiotherapy (79.6%) and the difference was statistically significant (P=0.010); but no statistical significance of radiotherapy for stage â ¢ and chemotherapy for stage â ¡ or â ¢ patients (all P>0.05). The multivariate analysis showed surgical margin (HR=4.220, P=0.002), with/without standard treatment (HR=4.040, P=0.030) were independent risk factors associated with prognosis of UHGPS patients. Conclusions: For UHGPS with stage â ¡ or stage â ¢ in extremities and trunk soft tissue, patients with complete resection and standard treatment have improved prognosis. Therefore, standard treatment, including extensive resection for the first surgery, should be performed according to expert consensus in order to increase the long-term survival rate. Adjuvant radiotherapy should be performed for stage â ¡ patients.

Objective: To analyze the data of kidney transplantation with allografts from intracerebral hemorrhage donors of China donation after citizen's death (CDCD) and provide evidence to guide the clinical practice. Methods: The clinical data of CDCD donors (age ≥10 years)and corresponding kidney allograft recipients, which were done by Second Xiangya Hospital of Central South University during January 1 2013 to December 31 2017, were analyzed retrospectively. Results: 327 CDCD cases were analyzed, the number and percentage of intracerebral hemorrhage donors were gradually increasing and the percentage reached to 39.5% in 2017. The discarding rateof kidney allografts donated by intracerebral hemorrhage donors was higher than those donated by non-intracerebral hemorrhage donors, but intracerebral hemorrhage donor may not be a risk factor for DGF after the rigorous evaluation of kidney allografts. For 145 primary recipients transplanted in 2016 and had a 22±4 month follow-up, the recipients accepted the kidney from intracerebral hemorrhage donors had a higher level of serum creatinine[(130±60)µmol/L vs (111±38) µmol/L,P<0.05]and a lower eGFR[(61±23) ml·min(-1)·(1.73m(2))(-1) vs (70±23) ml·min(-1)·(1.73m(2))(-1),P<0.05] compared to the recipients accepted the kidney from non-intracerebral hemorrhage donors. Conclusion: The number and percentage of organ donation from intracerebral hemorrhage donor is increasing, but the intracerebral hemorrhage donor may be a risk factor for long-term outcome of kidney transplantation.

The treatment option in chronic hepatitis B (CHB) patients with persistent low-level viremia despite entecavir or tenofovir monotherapy is unclear. This study investigated the development of hepatocellular carcinoma (HCC) or cirrhosis in hepatitis B e antigen (HBeAg)-positive high viral load CHB patients, according to the time needed to achieve complete viral suppression. A total of 325 HBeAg-positive CHB patients with high viral load who were recently started on antiviral therapy with entecavir or tenofovir were included. The enrolled patients were divided into 2 groups with 4 separate criteria based on the time needed to achieve complete viral suppression: within 1, 2, 3 or 4 years of therapy initiation. The outcomes were development of HCC and cirrhosis. The cumulative incidence of HCC was significantly higher in patients failing complete viral suppression within 1 year (hazard ratio (HR), 4.54; 95% confidence interval (CI), 1.03-19.93; P = .045) or 2 years (HR, 3.38; 95% CI, 1.24-9.23; P = .018), than patients who achieved complete viral suppression within 1 or 2 years, respectively. Cumulative incidence of cirrhosis was also significantly higher in patients failing suppression within 1 year (HR, 1.95; 95% CI, 1.04-3.66; P = .037) or 2 years (HR, 2.44; 95% CI, 1.41-4.22; P = .001). When the time for achieving viral suppression exceeded 2 years, the cumulative incidence of HCC or cirrhosis was not different regardless of viral suppression. Complete hepatitis B virus suppression within 2 years of antiviral therapy initiation is associated with risk reduction in HCC or cirrhosis development.

Nucleot(s)ide analogues (NAs) reduce the risk of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients. However, the risk of HCC is reportedly higher for NA-treated patients than for patients in the inactive CHB phase. This study aimed to compare the long-term outcomes of CHB patients with NA-induced viral suppression and those of patients with inactive CHB. This retrospective study involved 1118 consecutive CHB patients whose HBV DNA level was continuously <2000 IU/mL during follow-up with/without antiviral agents. The patients were classified into inactive CHB (n = 373) or NA groups (n = 745). The primary endpoint was overall survival. Secondary endpoints included development of HCC and other liver-related events. The median duration of follow-up was 41.0 (interquartile range = 26.5-55.0) months. The difference in overall survival between the NA group vs. the inactive CHB group was not significant (hazard ratio [HR] = 0.78; 95% confidence interval [CI] = 0.33-1.85; P = .57). The NA group showed a significantly higher risk of HCC (HR = 3.44; 95% CI = 1.82-6.52; P < .01), but comparable risk for non-HCC liver-related events (HR = 1.02; 95% CI = 0.66-1.59; P = .93), compared with the inactive CHB group. Among patients with cirrhosis, the NA group showed a significantly lower risk of death (HR = 0.31; 95% CI = 0.097-0.998; P = .05) and non-HCC liver-related events (HR = 0.51; 95% CI = 0.31-0.83; P < .01), but a slightly higher risk of HCC (HR = 2.39; 95% CI = 0.85-6.75; P = .09), compared to the inactive CHB group. The overall survival of untreated patients with inactive CHB and of CHB patients achieving viral suppression with NA was comparable. However, NA treatment of cirrhotic patients was significantly associated with longer overall survival and lower risk of liver-related events.

Nucleos(t)ide analogues (NAs) have been shown to decrease the risk of hepatocellular carcinoma (HCC) recurrence. This study evaluated whether high-potency NAs (entecavir and tenofovir disoproxil fumarate [TDF]) reduce the risk of tumour recurrence more potently than low-potency NAs after curative treatment of hepatitis B virus (HBV)-related HCC. This study included 607 consecutive HBV-related HCC patients treated with surgical resection or radiofrequency ablation. The patients were categorized into three groups according to antiviral treatment: group A (no antiviral; n = 261), group B (low-potency NA; n = 90) and group C (high-potency NA; n = 256). The primary end-point was recurrence-free survival (RFS). During the duration of follow-up, the median RFS was 29.4, 25.1, and 88.2 months in groups A, B and C, respectively (P < .001, log-rank test). The multivariate Cox analysis indicated that group C had a significantly longer RFS than both group A (adjusted hazard ratio [HR] = 0.39, P < .001) and group B (adjusted HR = 0.47, P < .001). When baseline characteristics were balanced using inverse probability weighting, group C still had a significantly longer RFS than group A (adjusted HR = 0.46, P < .001) and group B (adjusted HR = 0.59, P = .007). Group C had significantly lower risk of viral breakthrough than group B (HR = 0.19, P < .001). Viral breakthrough was an independent risk factor for shorter RFS among groups B and C (adjusted HR = 2.03, P = .007, time-dependent Cox analysis). Antiviral agents with high genetic barrier to resistance (entecavir and TDF) reduced the risk of HCC recurrence compared with other antivirals and no antiviral treatment, especially in patients with high baseline viral load.

OBJECTIVES: Adherence to treatment among most type 2 diabetes mellitus (T2DM) patients is relatively poor in rural China. The present study aimed to explore the perspectives of rural T2DM patients and health workers on a text message-based intervention (TMI) for increasing patients' adherence in rural China. STUDY DESIGN: Qualitative study. METHODS: Six focus group discussions with T2DM patients, six with village doctors, and three with public health physicians were conducted in Xianning city during 2015. Semistructured interview guides were employed to facilitate qualitative data collection. Audio recordings of the sessions were transcribed verbatim, and theme analysis was performed. RESULTS: Based on the participants' reports, T2DM patients had insufficient knowledge about diabetes and suboptimal adherence to treatment in rural China. Most of the participants had a positive attitude toward this novel TMI approach to improving patients' treatment adherence and knowledge. The perceived potential barriers to the utilization of TMI included poor eyesight and educational background and gradually losing interest during a long-term intervention. The suggestions for successfully implementing this strategy included family or social support, applicability of the text message content, adequate frequency and timing of sending the messages, and combining of messages with other educational formats. CONCLUSION: A TMI is a promising option for improving T2DM patients' adherence to treatment in rural China. The findings of the present study can contribute knowledge to the application of TMI in similar settings.

Objective: To evaluate the clinicopathological characteristics of foot and ankle soft tissue and bone tumor, and to analyze the prognosis and the related factors of malignant tumors in this site. Methods: 74 patients with soft tissue and bone tumors of foot and ankle from January 2006 to February 2017 were retrospectively analyzed. The clinicopathological characteristics, the treatment and survival status of malignant tumors were followed up, and the clinical and therapeutic factors related to prognosis were analyzed. Results: Of the 74 patients, 34 were males and 40 were females. The male to female ratio was 1â¶1.18; the age ranged from 12 to 64 years and the median age was 42 years. Tumors located in forefoot of 22 cases, 22 in midfoot, 10 in hind foot, 14 in ankle joint and 6 in multiple sites. 14 cases were bone tumors, including 7 benign and 7 malignant, and 60 cases were soft tissue tumors, including 14 benign and 46 malignant. The most common malignant soft tissue tumors were synovial sarcomas (13 cases), and the most common benign soft tissue tumors were hemangiomas (4 cases). 44 cases of malignant tumors underwent surgery were followed up, of which were 7 bone and 37 soft tissue malignant tumors. Limb salvage surgeries were performed in 33 cases and amputation in 11 cases. The median follow-up time was 69.8 months, and the median survival time was 40.7 months. The 1-year, 3-year and 5-year survival rate of soft tissue malignant tumors was 88.0%, 73.0%, and 63.0%, respectively. The 1-year, 3-year and 5-year survival rate of bone malignant tumors was 86.0%, 57.0% and 57.0%, respectively. Univariate analysis showed that the prognostic factors affecting 5-year survival rate were tumor size and adjuvant therapy (P<0.05). Patient's gender, age, tumor location, histological type and surgical procedure had no effect on overall survival(P>0.05). Multivariate analysis showed that tumor size was an independent prognostic factor (RR=7.262, P=0.005). Conclusions: Forefoot and midfoot are more common in foot and ankle soft tissue and bone tumors. Synovial sarcoma is the most common diagnosis in malignant soft tissue tumors, and hemangioma is the most common diagnosis in benign soft tissue tumors. The prognostic factor of malignant soft tissue and bone tumors in foot and ankle is tumor size. Patients with the tumor size of 5 cm or more have a worse prognosis.

Objective: To evaluate the clinical value of preoperative (18)F-Fludeoxyglucose ((18)F-FDG PET-CT) in lymphatic metastasis diagnosis of cutaneous melanoma on extremities and trunk. Methods: 112 patients with cutaneous melanoma pathologically of extremities and trunk from January 2006 to December 2016, who received (18)F-FDG PET-CT examination preoperatively, were retrospectively reviewed. The correlations between the maximal diameters of lymph nodes, the maximal standard uptake value (SUV) and the diagnostic impression grades of PET-CT examination, and the final pathological diagnosis were analyzed. The correlations between Breslow thickness of primary lesions and the diagnostic impression of PET-CT examination were also analyzed. All the above were analyzed with Receiver Operating Characteristic (ROC) curve to get the cut-off value. Based on the final results of pathological diagnosis of lymph nodes as the golden standard, the statistically significant indicators of ROC curve analysis were used to evaluate the diagnostic effect, as well as to calculate the sensitivity, specificity and accuracy. With gender, age, maximal diameter of lymph nodes, maximal SUV, diagnosis impressions, and Breslow thickness as the independent variables and pathological diagnosis results of lymph nodes as the dependent variable, two-class stepwise Logistic regression analysis was used to determine the independence of diagnostic indicators. ROC curve analysis and log rank test were used to analyze the relationship between Breslow thickness and patient survival. Results: To evaluate melanoma patients' lymph node status, the results of ROC curve analysis showed that the area under the curve of lymph node maximal diameter, maximal SUV, diagnosis impression of PET-CT examinations were 0.789, 0.786 and 0.816, respectively (all P<0.05). The cut-off values were 0.85 cm, 1.45 and 2.5, respectively. The sensitivity of the cut-off values to determine the status of lymph nodes in melanoma patients were 71.4%, 64.9% and 72.1% respectively, and the specificities were 85.2%, 88.7% and 87.0% respectively. Multivariate Logistic regression analysis showed that PET-CT diagnosis impressions had independent diagnostic significance for the lymph node status of melanoma patients (OR=11.296, 95%CI: 2.550~50.033). The area under the curve of Breslow thickness evaluating PET-CT diagnostic impression is 0.664 (P=0.042) and the cut-off value was 4.25 mm. The survival rate of the patients with Breslow thickness ≥ 4.25 mm was lower than that in the group <4.25 mm (P=0.006). Conclusions: (18)F-FDG PET-CT can help to evaluate metastases and make treatment decisions for cutaneous melanoma of extremities and trunk, especially for patients whose primary lesion's Breslow thickness has reached more than 4.25 mm. For the patients whose maximal SUV of regional lymph node is higher than 1.45 and short diameter of the largest lymph node is larger than 0.85cm, the possibility of metastases should be considered.

Objective: To summarize the clinical data of pre-implantation biopsy donors in our hospital and explore the clinical characteristics of those donors in pathological high-risk, and to provide references for the selective histological evaluation of extended criteria donor kidneys. Methods: We retrospectively reviewed the clinical data and pre-implantation renal pathologic score of donors from January 1, 2015 to May 1, 2017.During this period, 247 cases of donation after citizen's death (DCD) occurred.After clinical evaluation and selective machine perfusion( Lifeport) evaluation, 30 cases of pre-implantation pathological evaluation were performed.According to Remuzzi scores, donors were divided into low-risk and high-risk group.Nine cases of low-risk group (bilateral kidney's Remuzzi score ≤3) and 16 cases of high-risk group (bilateral or unilateral kidney's Remuzzi score ≥4, severe glomerular micro-thrombi or severe tubular necrosis) were included.Five cases of donors were excluded due to only unilateral renal pathological result available.Both high-risk and low-risk groups' clinical data, including sex, age, height, body weight, body mass index, proteinuria, hematuria, urinary glucose, baseline or admission serum creatinine, serum creatinine before procurement, history of hypertension and/or diabetes mellitus, cardiopulmonary resuscitation or not, with or without the history of shock, urine output prior to acquisition, macroscopical manifestations of donor kidney, cause of death were statistically analyzed. Results: The donors' baseline serum creatinine/upper limit of normal serum creatinine range in high-risk group were significantly higher than that in low-risk group [(129.8±42.2)% vs(92.4±30.5)%, P=0.029]. The poor macroscopical manifestations of donor kidneys were significantly more frequent in high-risk group than that in low-risk group (12/16 vs 0/9, P= 0). No significant differences between two groups were found regarding their age, height, weight, BMI, proteinuria, hematuria, urine glucose, pre-procure creatinine level, history of hypertension and/or diabetes mellitus, cause of death and so on (P>0.05). Conclusions: After clinical evaluation and selective Lifeport evaluation, donor grafts of whose baseline serum creatinine levels increased beyond normal range and of whose grafts' macroscopical manifestations were poor, should undergo pre-implantation pathological evaluation further.Also, it is reasonable to perform pre-implantation biopsy in cases of equivocal results after Lifeport evaluation.This will be beneficial to identify histological high-risk donors and also be predictive to allocate the grafts.

Methods: The model of steatosis was established with induction of oleic acid and palmitic acid and was intervened by rapamycin. The changes in lipid droplets were observed after staining the cells with oil Red O. Intracellular triglyceride (TG) contents in cells were measured by TG kit. mTOR, S6K1, and SREBP-1c mRNA expression levels were detected using QRT-PCR. Western blot was used to determine protein expression levels of mTOR, S6K1 and SREBP-1c. Results: Both fatty acids increased lipid droplets in HepG2 cells. Fatty degeneration with elevated TG occurred with significant changes in oleic acid group lipids. Rapamycin alleviated lipid deposition caused by oleic acid and palmitic acid and inhibited their induction of increased expression of mTOR, S6K1, and SREBP-1c. QRT-PCR and Western blot results showed that mRNA and protein expressions of mTOR, S6K1, and SREBP-1c in oleic acid and palmitic acid group were significantly higher than the control group (P < 0.05). The increase was more pronounced in the palmitic acid group (P < 0.05); however, after rapamycin intervention, the expression of mRNA and protein in the three groups were significantly lower (P < 0.05), and the change in palmitic acid group was more pronounced (P < 0.05). Conclusion: Oleic acid and palmitic acid can induce lipid deposition in HepG2 cells and increase expression of every component of mTOR/S6K1/SREBP-1c pathway; however, Oleic acid-induced lipid deposition is more pronounced, and the mTOR, S6K1, and SREBP-1c pathway change is more obvious in palmitic acid. Rapamycin has high potent inhibitory effect on palmitic acid-induced lipid deposition. These results specify that lipid synthesis involved in the mTOR/S6K1/SREBP-1c pathways are mainly associated to palmitic acid in HepG2 cells, whereas other signaling pathway may mediate oleic acid-induced lipid synthesis.

Objective: To explore the night sleep quality of shift nurses and the current situation of their daytime tiredness, sleepiness, and to provide evidence for nursing administrators and managers to allocate human resources reasonably and prevent adverse events. Methods: The cross-sectional method was utilized to conduct a questionnaire survey among shift nurses in a tertiary teaching hospital in Shandong Province from March to May inclusive, 2017. Results: There was a total of 233 valid questionnaires returned. The prevalence of sleep disorder, daytime tiredness and sleepiness was 45.92%, 16.31% and 13.30%, respectively. The differences of the nurses' sleep quality at night between different ages, marriages, educational backgrounds and professional titles were statistically significant (P<0.05) , while the differences of daytime burnout and sleep state between different shift systems were statistically significant (P<0.01) . Night sleep quality was positively correlated with daytime tiredness and sleepiness (P<0.05) . The results of multiple linear regression analysis showed that age, marriage, educational background and professional title had an impact on nurses' sleep quality at night (P<0.05) . Shift system had an impact on nurses' daytime burnout and sleep apnea (P<0.01) . Conclusion: There was a high prevalence of night sleep disorder, daytime tiredness and sleepiness among the shift nurses. Nursing administrators and managers should pay more attention to the night sleep quality of nurses who aged over 30 years old, married, without a bachelor degree and those with a lower professional rank. Furthermore, the current situation of daytime tiredness and sleepiness among two-shift only nurses was worrisome.

We investigated whether serum deprivation induces islet amyloid polypeptide (IAPP) oligomer accumulation and/or a proinflammatory response and, if so, whether the addition of interleukin (IL)-1 receptor antagonist to the culture medium can relieve the proinflammatory response during serum-deprived culture of nonhuman primate (NHP) islets. After culture in medium with and without Ana under serum-deprived culture conditions, IAPP oligomer/amyloid accumulation, in vitro viability, islet function, cytokine secretion, and posttransplantation outcome in streptozotocin-induced diabetic nude mice were determined in islets isolated from heterozygote human IAPP transgenic (hIAPP+/- ) mice and/or NHP islets. Serum deprivation induced accumulation of IAPP oligomer, but not amyloid, in NHP islets. Anakinra (Ana) protected islets from the serum deprivation-induced impairment of in vitro viability and glucose-stimulated insulin secretion and attenuated serum deprivation-induced caspase-1 activation, transcription, and secretion of IL-1ß, IL-6, and tumor necrosis factor-α in hIAPP+/- mice and NHP islets. Supplementation of medium with Ana during serum-deprived culture also improved posttransplantation in vivo outcomes of NHP islets. In conclusion, serum deprivation induced accumulation of IAPP oligomers and proinflammatory responses in cultured isolated islets. Supplementation of the culture medium with Ana attenuated the functional impairment and proinflammatory responses induced by serum deprivation in ex vivo culture of NHP islets.

Objective: To investigate the clinicopathological features and prognosis of malignant peripheral nerve sheath tumors (MPNST). Methods: We retrospectively reviewed the clinical data of MPNST patients who were treated at Cancer Institute & Hospital, Chinese Academy of Medical Science from January 1999 to January 2016. A total of 140 patients with 66 male and 74 female with MPNST were enrolled in the study. The median age was 40 at the time of diagnosis. Survival analysis were estimated by Kaplan-Meier method and Log rank test. Multivariate analysis were estimated by Cox proportional hazards regression model. Results: The median follow-up time was 43.0 months. The 3- and 5-year overall survival (OS) rates were 56.4% and 48.6%, respectively. The 3-year local recurrence (LR) rate and distant metastasis (DM) rates were 42.9% and 49.3%, respectively. Univariate analysis showed that the tumor location, AJCC stage, S-100, radiotherapy and margin status affected 5-year OS rate (all P<0.05). The tumor location, AJCC stage, S-100, Ki-67 staining, margin status, radiotherapy and chemotherapy affected 3-year LR rate (all P<0.05). The tumor location, AJCC stage, S-100, Ki-67 staining and margin status affected 3-year DM rate (all P<0.05). Multivariate analysis showed that the tumor location, AJCC stage, S-100 were independent factors for 5-year OS rate (all P<0.05). The tumor location, Ki-67 staining and chemotherapy were independent factors for LR (all P<0.05) while the AJCC stage, margin status and Ki-67 staining were independent factors for DM (all P<0.05). Conclusions: MPSNT is an aggressive tumor with poor prognosis. Multiple factors were identified in this study. Patients with the tumor located at head and neck, advanced AJCC stage and negative S-100 usually have a low 5-year overall survival rate. Patients with the tumor located at head and neck, Ki-67 staining ≥ 20% and without chemotherapy had a higher tendency of local recurrence. Poor prognosis factors for DM were advanced AJCC stage, positive margin and Ki-67 staining ≥ 20%.

BACKGROUND AND OBJECTIVE: The predictability of conventional periodontal treatments for damaged periodontal tissue is limited, particularly on the regeneration of new cementum. As signaling molecules, a range of growth factors has been used to promote periodontal regeneration on periodontal ligament (PDL) and cementum defects. A preameloblast-conditioned medium (PA-CM) was prepared from cultured murine apical bud cells, which can differentiate into ameloblasts. We examined the effect of PA-CM on PDL cells and cementoblasts in vitro and evaluated histologically the effects of PA-CM on the regeneration of experimentally induced periodontal defects in vivo. MATERIAL AND METHODS: In vitro, the effects of PA-CM on the migration of human PDL cells were examined using a scratch wound healing assay and a transwell assay. The differentiation and mineralization potential of PA-CM-treated human PDL cells and murine cementoblastic OCCM-30 cells was examined by real-time polymerase chain reaction and Alizarin red-S staining. In vivo, six mongrel dogs (12-16 kg; 6-8 mo old) were used. Twenty-four roots were replanted with either, (i) only periodontal defects (n = 12; control group), or (ii) periodontal defects and PA-CM treatment (n = 12; experimental group). In the experimental group, the PDL and cementum between notches was removed using a Gracey curette and soaked in 0.08 mL water containing 80 µg of a PA-CM for 2 min. The dogs were killed at 4 and 8 wk post-surgery. RESULTS: The in vitro results showed that PA-CM stimulated the migration of PDL cells and promoted the differentiation and mineralization of PDL cells and cementoblasts. Real-time polymerase chain reaction analysis revealed stronger expression of Runx2, Osx, OC, Bsp and Cap mRNAs in the PA-CM-treated PDL cells and cementoblasts than those in the control cells. In vivo, newly formed PDL-like tissue and cementum-like tissue were observed partially between the root surfaces and newly formed bone in the experimental group. The regenerated PDL-like tissue in the experimental group was significantly higher than that in the control group at 8 wk (p < 0.05). The replacement resorption on the experimental group was significantly lower than that in the control group at 8 wk (p < 0.05). In addition, the amount of newly formed cementum-like tissue in the experimental group was significantly higher than that in the control group at 4 and 8 wk (p < 0.05). CONCLUSION: These results suggest that PA-CM has the potential to regenerate periodontal tissues in PDL and cementum defects.
