Changes of visual quality and influencing factors after primary angle-closure glaucoma complicated with cataract / 国际眼科杂志(Guoji Yanke Zazhi)

In recent years, the combined surgery of phacoemulsification, intraocular lens implantation, and goniosychialysis has gradually emerged as a primary and effective approach in treating primary angle-closure glaucoma with cataracts. However, with the continuous progress of medical technology, postoperative intraocular pressure control is no longer the sole pursuit. Patients increasingly aspire to achieve higher postoperative visual quality. In order to ensure that patients attain a better refractive status and higher visual quality postoperatively, it is essential to minimize the negative impact caused by primary angle-closure glaucoma. This involves personalized selection of different intraocular lenses or calculation formulas,etc. Evaluation metrics for visual quality encompass visual acuity, contrast sensitivity, higher-order aberrations, subjective perception, etc. Therefore, this paper provides a comprehensive review of postoperative refractive shift, higher-order aberrations, contrast sensitivity and their influencing factors, and the selection of intraocular lenses for patients undergoing combined surgery for primary angle-closure glaucoma with cataracts.

Remote sensing and GIS-based study of land use/cover dynamics, driving factors, and implications in southern Ethiopia, with special reference to the Legabora watershed.

This paper investigates the trends, drivers, and consequences of LULC changes in Legabora watershed, Ethiopia, by utilizing remote sensing and geographic systems. Landsat Maltispectiral scanner (MSS), Thematic Mapper (TM), Enhanced Thematic Mapper (ETM+), and Operational Land Imager (OLI) images of years 1976, 1991, 2001, and 2022, respectively, were used to study the dynamics of LULC. Essential image pre-processing steps were carefully carried out to correct distortions caused by sensor limitations. Eight main LULC categories were identified based on supervised image categorization methods and the maximum likelihood classification algorithm.The findings of change detection and cross-tabulation matrix demonstrate that there has been a significant increase in the area of cropland 345.1 ha/year, settlement 5.9 ha/year, forest 38.2 ha/year, and degraded lands 2.56 ha/year, respectively, over the period between 1976 and 2022. In contrast, considerable decreases were observed in grasslands (-248 ha/year) and shrublands (-144 ha/year), whereas other LULC categories augmented. The results revealed that the overall accuracy rates stood at 88.3 %, 88.4 %, and 85.6 % for 1976, 1991, and 2022, respectively. The overall kappa coefficient demonstrated values of 0.86 %, 0.86 %, and 0.83 % for the same period. Surveyed respondents perceived population growth, settlement, agricultural expansion, and infrastructure development as the most noticeable drivers of these LULC changes. In contrast, deforestation, land degradation, lack of livestock fodder, and biodiversity loss were identified as the main consequences of LULC changes. The factors and implications addressed in this study may be helpful tool for the formulation and implementation of evidence-based land use policies and strategies within in the study area and elsewhere.

Comprehensive evaluation and analysis of laboratory resource allocation in 14 blood stations based on entropy weight -TOPSIS method / 中国输血杂志

【Objective】 To investigate the resource allocation status of blood testing laboratories in 14 blood stations in Gansu Province, explore the impact of differences in basic conditions on the comprehensive testing ability of laboratories, so as to promote the homogenization and standardization of blood screening capacity in blood stations in Gansu and improve blood safety and effectivenes. 【Methods】 An evaluation index system of laboratory resource allocation was constructed and a question-naire was designed. The data of human resources, infrastructure and key equipment of 14 blood stations were collected. The entropy weight -TOPSIS method was used to evaluate and rank the resource allocation of 14 blood stations. 【Results】 In the comprehensive evaluation of blood testing laboratory resource allocation in 14 blood stations in Gansu, the top three were laboratories A, B and I, and the last three were laboratories G, M and J. On the whole, the main issue was unreasonable structure of human resources: most laboratories had unreasonable age structure; except for Laboratory A, there was no personnel with bachelor's degree or above in laboratories; most laboratories had not established a team with intermediate professional titles. In terms of infrastructure, the size of seven laboratories could not meet the needs of modern laboratory testing, and all eight blood stations had no spare nucleic acid laboratories nor a mutual spare laboratory with other blood stations As for the key equipment, 5 laboratories had no automatic blood grouping diagnostic instrument, 5 laboratories only had one set of enzyme immunoassay detection system, 3 laboratories had no spare equipment for the key equipment, which means if the equipment failure could not be repaired in time, the release of results would be affected. 【Conclusion】 There were significant differences in human resources, infrastructure and key equipment of blood testing laboratories in 14 blood stations in Gansu, which had a great impact on laboratory testing capacity and subsequent development. It is suggested that governments at all levels and health administrative departments optimize the input of laboratory resource allocation according to the blood collection volume of blood stations to gradually narrow the differences in resource distribution between different regions, improve the degree of laboratory automation and optimize the personnel structure, so as to build high-quality and efficient blood testing laboratories and ensure the safety of clinical blood use.

Land use and land cover change, and analysis of its drivers in Ojoje watershed, Southern Ethiopia.

There have been incredible changes that have taken place in the land use pattern globally over the last 50 years, which resulted from environmental degradation and climate change impacts. Quantitative analysis of the LULC dynamics helps in land-use management and ecosystem degradation at large. The study was conducted in the Doyogena district, southern Ethiopia to identify LULC change dynamics, and analyze the driving forces using combined approaches: remote sensing, field observations, in-depth household interviews, key informants, and Focus Group Discussions (FGDs). A supervised maximum likelihood image cataloging method was employed in conjunction with feature extraction of satellite images to categorize and map LULC classes of the study area. Satellite image handing out, classification technique, and remotely sensed data were processed using ArcGIS map 10.6, and ERDAS Imagine 2014. Common LULC categories were identified, and a change analysis was conducted. Accordingly, seven LULC categories were determined. The result showed a considerable decline in forestland from 1756.7 ha (38.8%) in 1973 to 71.6 ha (1.6%) in 2020. Similarly, wetlands have declined successively from 16.8 in 2000-2010 to 6.3 in 1986-2020 ha/year over the last three and half decades respectively. On the other hand, cropland has increased from 34.1% in 1986-2000 to 46.3% between 1986-2020, which is linked to population growth, settlement, and expansion of farmlands. The study watershed has experienced a considerable change in LULC change over the last >3 decades. Hence, local and national regimes should implement sustainable land planning, management strategies including integrated land- use planning, and policy reform into development projects and programs.

Efficacy, safety, and controversy of ultrasound-guided radiofrequency ablation in the treatment of T1N0M0 papillary thyroid carcinoma.

Objective: To evaluate the safety effect, and controversy on the treatment outcomes of radiofrequency ablation (RFA) for T1N0M0 papillary thyroid carcinoma (PTC). Materials and methods: This study is assessed the medical records of 142 patients with primary T1N0M0 PTC tumors after RFA between 2014 and 2022. 4 patients underwent delayed surgery (DS) after RFA and 411 T1N0M0 patients underwent DS were recorded. Outcomes were compared between RFA and DS groups after propensity score matching (PSM). Results: The maximal diameter (MD) and volume (V) increased in months 1 (P < 0.01) and reduced after the 6-month follow-up (all P < 0.01). The disappearance and disease progression rates were 53.5% and 2.1%, respectively. The complication and disease progression rates had no significant difference between RFA and DS (P>0.05). In some cases, the tumors were not fully inactivated after RFA, and the central compartment lymph node (CCLN) were metastasis. The CCLN metastasis rate was 13.4%. MD, V and clustered calcifications were independent risk factors for CCLN metastasis by univariate analysis. Conclusions: RFA is an effective and safe treatment option in selected patients with solitary T1N0M0 PTC. There are the risks of tumor incompletely ablated and CCLN metastasis.

Occurrence of macroprolactinemia in schizophrenia patients treated with risperidone or amisulpride.

OBJECTIVE: To investigate macroprolactinemia caused by antipsychotics and its clinical significance. METHODS: A total of 133 patients with schizophrenia were selected, all of whom were treated with either risperidone or amisulpride alone. The levels of total prolactin (T-PRL) and macroprolactin (MPRL) were measured before treatment as well as the second, fourth, and sixth weeks of treatment. RESULTS: After 2 weeks of treatment, 75.09% (100/133) of the patients met the diagnostic criteria for hyperprolactinemia, the incidence of macroprolactinemia was 43% (43/100), and MPRL levels were positively correlated T-PRL levels. CONCLUSION: Risperidone and amisulpride caused hyperprolactinemia and macroprolactinemia; thus, detection of MPRL in the clinical setting should be performed as this phenomenon appears early in treatment (the second week) and continues, that can avoid unnecessary examination and treatment for asymptomatic patients with macroprolactinemia.

Conclusion:The low expression of EGFL6 can inhibit the proliferation of human bladder cancer cell 5637 in vivo and in vitro through the P13K-AKT signaling pathway.

Study on the correlation between preoperative echocardiography indicators and postoperative prognosis in children with ventricular septal defect / 中华超声影像学杂志

Objective:To explore the correlation between preoperative echocardiography indicators and surgical prognosis of children with ventricular septal defect (VSD) and conduct verification based on significant indicators and indicator ratios.Methods:A total of 1 357 children with VSD who were admitted to the Children′s Hospital, Zhejiang University School of Medicine from June 2016 to June 2021 were selected. Various measurements including the size of the VSD, left ventricular ejection fraction (LVEF), left atrial (LA) diameter, the aortic (AO) flow rate, the tricuspid regurgitation velocity and pressure gradient were extracted from preoperative echocardiography reports. This paper explored the correlation between echocardiography reports indicators, indicator ratios and postoperative auxiliary ventilation time, respectively. The patients were divided into two groups according to whether there were complications, and the differences of echocardiography reports indicators between the two groups were compared. A linear regression model was established to predict the postoperative auxiliary ventilation time using these indicators, and the least absolute shrinkage and selection operator (LASSO) regression model was used for variable selection.Results:The VSD size and AO flow velocity were weakly correlated with the postoperative auxiliary ventilation time ( r=0.32, 0.25; all P<0.01). There was no significant correlation between VSD flow velocity and postoperative auxiliary ventilation time. The AO flow velocity/VSD flow velocity and LVEF/VSD flow velocity were strongly correlated with the postoperative auxiliary ventilation time ( r=0.67, 0.51; all P<0.01). In the significance test, there were no significant differences in tricuspid regurgitation flow velocity, tricuspid regurgitation pressure gradient, LA diameter, and LVEF between the complication group and the non-complication group(all P>0.01). However, the ratio of LVEF/tricuspid regurgitation velocity in the complication group was significantly lower than that in the non-complication group, and the ratio of tricuspid regurgitation pressure gradient/LA diameter was significantly higher than that in the non-complication group (all P<0.01). The postoperative auxiliary ventilation time of VSD patients was predicted on an independent test set, with an R2 of 0.51. Conclusions:Echocardiography report indicator ratios of AO flow velocity/VSD flow velocity and LVEF/VSD flow velocity have strong correlations with postoperative auxiliary ventilation time in children with VSD, and the ratios of LVEF/tricuspid regurgitation velocity and tricuspid regurgitation pressure gradient/LA diameter are significantly different between groups with and without postoperative complications. The ratios of indicators can significantly improve this correlation and difference, which can be used to predict the prognosis of VSD operation.

【Objective】 To study the annual financial expenditure in blood stations with different scales, and to establish the regression equation between blood collection units and total expenditure. 【Methods】 The annual total expenditure, the per capita cost of serving population, as well as the collection units of whole blood and apheresis platelet of 24 blood stations were collected. The financial expenditure required for collecting 10 000U blood was calculated.The statistical analysis was carried out with SPSS statistical software. 【Results】 From 2017 to 2020, the total annual financial expenditure of 24 blood stations showed an upward trend. The total expenditure among blood stations was different. The per capita cost of servicing population in the areas where the 24 blood stations were located had been increasing year by year. The 24 blood stations were divided into two grades according to the blood collection volume as 50 000 U, and the relationship equation between the blood collection volume and the annual total expenditure had been established. After testing, each equation was effective(P<0.05); There was no difference in the financial expenditure required for collecting 10 000U blood among blood stations with different scales. 【Conclusion】 From 2017 to 2020, the blood stations with an annual collection volume more than 50 000 U demonstrated a higher financial expenditure and the per capita cost of serving population than those <50 000 U. The blood collection volume of blood stations is significantly correlated with the annual total expenditure and the per capita cost of serving population.

Protocol-optimizing study of combining Tuina and horse-riding squat exercise for knee osteoarthritis / 针灸推拿医学（英文版）

Objective: To evaluate the efficacy of Tuina (Chinese therapeutic massage) manipulation plus horse-riding squat exercise in treating knee osteoarthritis (KOA) and optimize the combining protocol. Methods: Based on a 2×2 factorial design, 120 eligible KOA patients were randomized into a manipulation group (group A1B2), a manipulation plus horse-riding squat group (group A1B1), a sitting knee-adjustment group (group A2B2 group), and a sitting knee-adjustment plus horse-riding squat group (group A2B1), with 30 cases in each group. The intervention was conducted three times a week, lasting for four weeks. The Western Ontario and McMaster Universities osteoarthritis index (WOMAC) was taken as the major measure for efficacy evaluation (including three component scores, pain, stiffness, and daily function, and total score). Results: The three component scores (pain, stiffness, and daily function) and the total score of WOMAC showed significant differences after the intervention in the four groups (P<0.05). There were significant inter-group differences in the WOMAC stiffness score amongst the four groups after the intervention (P<0.05). In group A1B1, the step length, stride, walking speed, and knee joint flexion angle changed significantly after treatment (P<0.05). After the intervention, the step length changed significantly in group A1B2 (P<0.05), and the walking speed changed significantly in group A2B1 (P<0.05). There were no significant differences in the step length, stride, walking speed, or knee joint flexion angle among the four groups (P>0.05). The extensor peak torque at 180 °/s changed significantly in group A1B2 after treatment (P<0.05). Neither the intra-group nor the inter-group comparisons of the four groups revealed significant differences in the other isokinetic muscle strength parameters (P>0.05). The main effect of manipulation showed significant in affecting the WOMAC pain and total scores (P<0.05). The main effect of horse-riding squat exercise showed significant in affecting the WOMAC pain and stiffness scores (P<0.05). Conclusion: The four treatment protocols all can improve the symptoms of KOA, for instance, relieving pain and stiffness, and enhancing daily function. Group A2B1 produces the most eminent effect in relieving joint stiffness. The main effects of both manipulation and horse-riding squat exercise are significant in reducing pain. Besides, the main effect of horse-riding squat exercise is significant in relieving joint stiffness.

Akinesia deformation sequence in a fetus suspected by prenatal ultrasound and confirmed after mid-term termination / 中华围产医学杂志

We report a case of fetal akinesia deformation sequence (FADS), which was prenatally suspected on ultrasound and confirmed by whole exome sequencing and Sanger sequencing after mid-term termination. Prenatal ultrasonography revealed multiple abnormalities in a fetus at 21 +4 weeks of gestation, consisting of fixed posture of limbs, narrow thorax, markedly shrunken gastric vacuole, and thickened nuchal fold. After genetic counseling, the pregnancy was terminated, and the appearance of the fetus was consistent with the ultrasound findings. Whole exome sequencing and Sanger sequencing of the fetal tissue verified a compound heterozygous variation of the RAPSN gene--c.149_153delins AGATGGGCCGCTACAAGGAGATGG (p.V50Efs*114) and c.227T>C (p.L76P), which were inherited from the father and mother, respectively, ultimately confirming the diagnosis of FADS.

Clinical study of pre-transplant immunotherapy effects on the prognosis of recipients with hepatocellular carcinoma after liver transplantation / 中华器官移植杂志

Objective:To explore the effect of pre-transplant immunotherapy on the prognosis of transplant recipients with hepatocellular carcinoma(HCC).Methods:From June 2018 to September 2021, retrospective analysis was conducted for clinical data of 19 HCC-liver transplant recipients receiving pre-transplant immunotherapy in affiliated Huashan Hospital of Fudan University. Pre-transplant immunotherapy regimen, adverse reactions, post-transplant acute rejection, tumor recurrence and metastasis and other complications were recorded. According to the preoperative tumor imaging and the changes of alpha-fetoprotein level, tumor change during recipient waiting period was judged by the mRECIST standard. According to whether or not there was partial tumor remission, they were divided into two groups of non-remission( n=13)and remission( n=6). Postoperative conditions of two groups were compared. Kaplan-Meier method was used for calculating the survival rate of recipients after transplantation and survival curve and Log-rank test utilized for comparing the recurrence-free and overall survival rates of recipients at 1 and 2 years post-operation. Results:A total of 19 liver transplant recipients received immunotherapy plus targeted and transcatheter arterial chemoembolization(TACE) before transplant. In non-remission group, tumor was stable( n=9)and progressive( n=4); 6 cases in remission group had tumor partial remission. Two recipients in non-remission group were pathologically confirmed by liver biopsy to have acute rejection(2/19, 10.5%)and both recovered after glucocorticoid + rATG and glucocorticoid therapy. In non-remission group, 2 patients died from septic shock post-operation. Among 3 patients of tumor recurrence and metastasis post-operation, 2 cases survived with tumor and 1 died after tumor recurrence and metastasis. In remission group( n=6), none had postoperative tumor recurrence and metastasis. The recurrence-free survival rates of non-remission group recipients at 1 and 2 years post-operation were 76.9% and 76.9% and recurrence-free survival rates in remission group were 100% and 100% respectively and inter-group difference in RFS was not statistically significant( χ2=1.468, P=0.226). The overall survival rates of recipients in non-remission group at 1 and 2 years post-operation were 76.9% and 76.9% respectively. And recipients in remission group were 100% and 100% respectively and no statistically significant inter-group difference existed in OS( χ2=1.292, P=0.256). Conclusions:Without a significantly higher risk of acute rejection after transplant, immunotherapy may be an effective option for bridging treatment before liver transplantation for HCC. And it remains necessary to expand the sample size for verifications and supports.

Objective:To compare the prognoses of salvage liver transplantation fulfilling the Criteria of Milan, University of California San Francisco(UCSF)and Hangzhou.Methods:Clinical data were retrospectively reviewed for 256 patients with recurrent hepatocellular carcinoma(HCC)undergoing donation after citizen death(DCD)liver transplantation(LT)from January 2015 to October 2019.They were divided into two groups of primary(PLT, n=175)and salvage(SLT, n=81). General profiles, tumor pathological characteristics and postoperative complications of two groups were compared by T-test, rank-sum or χ2 test.Kaplan-Meier method and Log rank test were employed for comparing overall survival rate(OS)and recurrence-free survival rate(RFS)between two groups.In SLT group, 31 cases fulfilled Milan criteria, 45 cases UCSF criteria and 69 cases Hangzhou criteria.OS/RFS of three groups were compared.According to there was downstaging or bridging treatment pre-LT, SLT group was divided into downstaging group(n=32)and non-downstaging group(n=49). OS/RFS of two groups were compared.According to the Rescit1.1 criteria, downstaging group were divided into remission group(n=14)and non-remission group(n=18)and OS/RFS of two groups were compared. Results:The operative durations of PLT and SLT groups were(439.5±74.9)and(475.1±83.4)min respectively.There was significant inter-group difference( P<0.05); However, no significant inter-group difference existed in amount of intraoperative bleeding, blood transfusion, postoperative hospital stay or incidence of postoperative complications(all P>0.05). No significant difference existed in OS/RFS between PLT and SLT groups( P>0.05). No significant difference existed in OS at 1/3/5 years post-SLT among Milan, UCSF and Hangzhou criteria groups(all P>0.05); However, RFS in Milan criteria group at 1/3/5 years post-SLT were 93.5%, 81.7% and 81.7% respectively.They were significantly higher than 68.9%, 59.7% and 59.7% in UCSF criteria group and 78.3%, 58.8% and 55.5% in Hangzhou criteria group(all P<0.05). For patients on downstaging therapy, OS in the Remission group at 1, 3 and 5 years post-SLT were 100%, 73% and 73% respectively, which was significantly higher than 83.3%, 49.4% and 0 in non-Remission group( P=0.042). RFS in the Remission group at 1, 3 and 5 years post-SLT were 100%, 62.5% and 46.9% respectively, which was significantly higher than 52.9%, 0 and 0 in no-Remission group( P=0.001). Conclusions:The survival outcome of SLT recipients is similar to that of PLT recipients.The overall survival of SLT recipients shows no significant difference between Milan, UCSF and Hangzhou criteria.However, SLT recipients fulfilling Milan criteria have the longest recurrence-free time.The prognosis of patients with remission after preoperative descending treatment is superior to that of patients without remission.

Effects of nedaplatin combined with docetaxel on serum tumor markers and T lymphocyte subsets in patients with ovarian epithelial carcinoma / 中国基层医药

Objective:To investigate the effects of nedaplatin combined with docetaxel on serum tumor markers and T lymphocyte subsets in patients with epithelial ovarian cancer.Methods:Ninety-two patients with epithelial ovarian cancer who received treatment from March 2016 to December 2017 were included in this study. They were randomly assigned to undergo nedaplatin combined with docetaxel (observation group, n = 46) or cisplatin combined with paclitaxel (control group, n = 46). Both groups received two 21-day courses of treatment. Serum tumor marker level, T lymphocyte subset level, clinical efficacy, incidence of adverse reactions, and 2-year survival rate were compared between the two groups. Results:After treatment, serum cancer antigen 125 (CA125), cancer antigen 199 (CA199), and carcinoembryonic antigen (CEA) levels were (45.84 ± 22.46) U/mL, (35.13 ± 15.03) U/mL, (16.21 ± 3.20) U/mL, respectively in the control group and they were (28.33 ± 20.11) U/mL, (14.82 ± 10.11) U/mL, (5.16 ± 1.33) U/mL, respectively in the observation group. After treatment, CA125, CA199, and CEA levels in each group were significantly decreased compared with before treatment. After treatment, CA125, CA199, and CEA levels were significantly lower in the observation group than in the control group ( t = 3.94, 7.61, 21.63, all P < 0.05). After treatment, the numbers of CD3 +, CD4 +, CD8 + cells in the control group were (16.22 ± 3.12)%, (15.20 ± 1.46)%, (29.21 ± 5.17)%, respectively, and they were (31.22 ± 4.11)%, (24.99 ± 1.71)%, (24.25 ± 4.45)% respectively in the observation group. After treatment, the numbers of CD3 + and CD4 + cells in the observation group were significantly higher than those in the control group ( t = 19.72, 29.53, both P < 0.05). After treatment, the number of CD8 + cells in the observation group was significantly lower than that in the control group ( t = 4.93, P < 0.05). Total response rate was significantly higher in the observation group than in the control group [78.26% (36/46) vs. 58.70% (27/46), χ2 = 4.08, P < 0.05]. The incidence of adverse reactions was significantly lower in the observation group than in the control group [23.91% (11/46) vs. 45.65% (21/46), χ2 = 4.79, P < 0.05]. The 2-year survival rate was significantly higher in the observation group than in the control group [43.48% (20/46) vs. 23.91% (11/46), χ2 = 3.94, P < 0.05]. Conclusion:Nedaplatin combined with docetaxel is highly effective on epithelial ovarian cancer. The combined therapy can greatly reduce serum CA125, CA199, and CEA levels but has no great effects on T lymphocyte subsets. It can increase the survival rate but has no serious adverse reactions.

Expression and clinical significance of CD24 in preoperative peripheral blood and cancerous tissues of hepatocellular carcinoma patients undergoing liver transplantation / 中华器官移植杂志

Objective:To explore the relationship between CD24 expression in preoperative peripheral blood as well as cancer tissue and clinical parameters and prognosis in patients with hepatocellular carcinoma (HCC) after liver transplantation (LT).Methods:From November 2018 to November 2019, clinical data were collected for 65 HCC patients and 41 patients with benign liver disease.The preoperative peripheral blood level of CD24 was detected by enzyme-linked immunosorbent assay (ELISA) and the expression of CD24 in cancerous foci and adjacent tissues examined by immunohistochemistry.Kaplan-Meier survival curves of differential CD24 expression were plotted and survival differences compared by Log-rank method.One-way ANOVA was utilized for examining the relationship between the expression level of CD24 and various clinicopathological parameters and multivariate Cox analysis for screening independent risk factors affecting patient prognosis.Results:The concentration of CD24 in preoperative peripheral blood (p-CD24) of HCC patients (6.51±2.33 μg/L) was significantly higher than that of patients with benign liver disease (4.10±0.91) μg/L, P<0.05.The positive rate of CD24 was obviously higher in cancerous tissues than that in adjacent tissues (87.7% vs. 4.6%, P<0.05). The peripheral blood level of CD24 was positively correlated with the expression intensity of CD24 in tumor tissues (t-CD24, r=0.570, P<0.001). The expression of CD24 (both in blood and cancer foci) was significantly correlated with preoperative level of gamma-glutamyl transferase (GGT), maximal tumor diameter, microvascular invasion, portal vein tumor thrombus, vessel carcinoma embolus and satellite focus ( P<0.05). The expression of CD24 in patients exceeding the Milan/UCSF criteria was higher than those fulfilling the criteria ( P<0.005). Patients with a higher expression of CD24 had worse overall survival and recurrence-free survival rates as compared to those a lower expression of CD24 ( P<0.05). Multivariate Cox analysis indicated that t-CD24 [OS: HR=3.661(1.005-13.333)], P=0.049; recurrence-free survival (RFS): [HR=4.331(1.887-9.942), P=0.001] and preoperative level of alpha fetoprotein (AFP) [OS: HR=4.900(1.590-15.097), P=0.006]; RFS: [HR=3.414(1.614-7.221), P=0.001] were independent risk factors for overall survival and recurrence-free survival in HCC patients undergoing LT. Conclusions:The preoperative peripheral blood level of CD24 in HCC patients undergoing LT indirectly reflects the expression of CD24 in cancerous tissues to a certain extent.And the expression of CD24 in cancerous tissue is one of the independent risk factors affecting OS and RFS of LT patients.

Expression of LncRNA-POU3F3 in thyroid cancer tissues and its predictive value for prognosis / 中华地方病学杂志

Objective:To investigate the expression of long non-coding RNA-POU3F3 (LncRNA-POU3F3) in thyroid cancer tissues and its predictive value for prognosis.Methods:Using case-control study, the thyroid cancer tissue samples and paracancerous tissue samples of 118 thyroid cancer patients who underwent surgery in Zhengzhou People's Hospital from May 2013 to August 2015 were collected, and 100 benign thyroid tumor tissue samples in the same period were selected as controls. Quantitative real-time PCR (qRT-PCR) was used to detect the expression of LncRNA-POU3F3 in thyroid tissues, receiver operating characteristic curve (ROC curve) was used to evaluate the diagnostic value of LncRNA-POU3F3 for thyroid cancer, and the correlation between LncRNA-POU3F3 level and clinicopathological characteristics and prognosis of patients was analyzed.Results:The qRT-PCR results showed that the expression level of LncRNA-POU3F3 in thyroid cancer tissues (4.02 ± 0.76) was higher than that in paracancerous tissues (3.18 ± 0.69) and benign thyroid tumor tissues (3.05 ± 0.66, P < 0.05). The area under the ROC curve of LncRNA-POU3F3 expression in the diagnosis of thyroid cancer was 0.886 [95% confidence interval (95% CI): 0.821 - 0.943, P < 0.05], the sensitivity was 83.7%, the specificity was 85.2%, and the diagnostic threshold was 3.45. High expression of LncRNA-POU3F3 (≥3.45) was found in thyroid cancer tissues with clinical stages Ⅲ - Ⅳ, tumor diameter ≥1 cm, multiple tumor foci and lymph node metastasis ( P < 0.05). Kaplan-Meier analysis showed that after 5 years of follow-up, 53 of the 118 patients with thyroid cancer survived. The 5-year survival rate of patients with low expression of LncRNA-POU3F3 ( < 3.45) was 77.42% (24/31), and that of patients with high expression of LncRNA-POU3F3 (≥3.45) was 33.33% (29/87), and there was a statistically significant difference in the 5-year survival rate between the two groups (χ 2 = 17.955, P < 0.05). Multivariate logistic regression analysis showed that clinical stage, tumor diameter, number of tumor foci, lymph node metastasis and LncRNA-POU3F3 expression were correlated with the survival time of patients with thyroid cancer ( P < 0.05). Conclusion:LncRNA-POU3F3 is highly expressed in thyroid cancer tissues, and its expression level is closely related to the clinicopathological characteristics and prognosis of thyroid cancer patients, which can be used as an important indicator for predicting the prognosis of thyroid cancer patients.

Noninvasive treatment of recurrent and acquired pectus excavatum with vacuum disk / 中华胸心血管外科杂志

Objective:To evaluate the effect of vacuum disk(VD) for non-invasive treatment of recurrent and acquired pectus excavatum(PE).Methods:From June 2017 to June 2019, 29 patients recruited from our outpatient clinic were included in this retrospective study and followed-up every 3 month according to the schedule. The patients were distributed into three groups(group 1 treated ≤6 months; group 2 treated from 6 months to 12 months; group 3 treated >12 months). The device should be applied regularly for more than 2 hours daily. The deformity chest wall was scanned by three-dimensional(3D)scanner at clinic, and the 3D-depth(3D-DE) and 3D-Haller index(3D-HI) of PE were calculated through Geomagic software.Results:In this cohort, 29 patients were eligible, 18 symmetrical PE and 11 asymmetric PE. The application time ranged from 3 months to 15 months(average 7.6 months). 4 paitents was lifted to a normal level, 23 patients were differently improved. However, 2 paitents had no improvement. The average of the depth and 3D-HI of all patients were improved from 17.7 mm to 11.6 mm and 1.739 to 1.598, respectively. It’s no statistically significant difference for the elevation of 3D-DE and 3D-HI between symmetrical and asymmetric PE( t=-2.821, P=0.558; t=0.074, P=0.068). When comparing the improvement of 3D-DE or 3D-HI of PE to the patient's treatment time, a statistically significant difference was proved between the group 2 and group 1( t=-2.261, P=0.014; t=-0.436, P=0.043), but not between the group 3 and group 2( t=-1.240, P=0.139; t=0.622, P=0.568). The main side effects include moderate subcutaneous hematoma(84%), petechial bleeding(27%), thoracalgia(32%) and chest tightness(17%), no other side effect appear till now. Conclusion:VD for treatment of recurrent and acquired PE is convenient, safe and noninvasive, which can be an alternative treatment for recurrent and acquired PE, However, long term of efficacy evaluation is still needed.

The risk analysis of long-term cognitive impairment after androgen deprivation therapy in elderly prostate cancer patients aged 75 years and over / 中华老年医学杂志

Objective:To examine the risk of long-term cognitive impairment in elderly prostate cancer patients aged 75 years and older undergoing androgen deprivation therapy(DAT), and to analyze the correlation between DAT and cognitive impairment.Methods:This was a retrospective cohort study.Elderly prostate cancer patients aged 75 years and older in the National Cancer Database(SEER)from 1996-2003 were included.According to whether ADT was received, patients were divided into the ADT group(n=82 514)and the control group(n=121 856). Baseline clinical data were compared between the two groups. Kaplan- Meier survival analysis and the Log- rank test were used to compare the incidence of cognitive impairment(dementia and Alzheimer's disease)between the two groups. Cox risk ratio regression analysis was used to assess the relationship between ADT and cognitive impairment. Results:A total of 204 370 patients were enrolled in this study.The mean age of patients was(79.2±4.6)years.Compared with the control group, the ADT group was older and had higher prostate specific antigen levels, higher proportions of poorly differentiated tumors, more complications and a higher proportion of patients receiving radiotherapy( P<0.05). During the follow-up of(12.1±3.3)years, a total of 41 661 cases of dementia were diagnosed, including 13 634 in the ADT group and 28 027 in the control group, and 28 945 cases of Alzheimer's disease were diagnosed, including 9 372 in the ADT group and 19 573 in the control group.Kaplan-Meier survival analysis and the log-rank test showed that the incidence of dementia in the ADT group was higher than that in the control group( χ2=8.10, P=0.004), and the incidence of Alzheimer's disease was also higher in the ADT group than in the control group( χ2=5.06, P=0.024). Cox regression analysis results showed that ADT significantly increased the risk of dementia( HR=1.71, 95% CI: 1.14-2.57, P=0.01)and Alzheimer's disease( HR=1.63, 95% CI: 1.08-2.46, P=0.02), compared with treatment that did not include ADT. Conclusions:The risk of dementia and Alzheimer's disease is increased in elderly prostate cancer patients aged 75 years and older after ADT.
