ABSTRACT

Parkinson's disease (PD) is a progressive neurodegenerative disease with a high clinical heterogeneity. According to its motor symptoms, PD patients are divided into predominant tremor-dominant, postural instability and gait difficulty-dominant/akinetic-rigid and mixed subtypes. Different subtypes show different prognostic characteristics and different sensitivities to drugs. Therefore, the early classification of PD is of great significance for the treatment and prognosis of the disease. This paper reviews the clinical classification methods of different subtypes of PD, summarizes the latest biochemical markers and imaging features, and analyzed the differences in incidence, prognosis and pathological mechanism. The current clinical treatment drugs and methods have been preliminarily targeted for treatment based on PD classification, and there are many animal models of PD subtypes have been studied, providing new methods and strategies for mechanism research and preclinical pharmacodynamics evaluation of PD subtypes.

ABSTRACT

Objective: To evaluate the therapeutic efficacy of acupuncture plus Dang Gui Bu Xue Qu Feng Tang for benign essential blepharospasm (BEB). Methods: A prospective randomized controlled trial was performed. A total of 105 participants were randomized 1:1:1 into an acupuncture group, a herbal medicine group and an acupuncture plus herbal medicine group. Participants in the acupuncture group received manual acupuncture treatment, twice a week. Participants in the herbal medicine group received Dang Gui Bu Xue Qu Feng Tang, oral administration, once a day. Participants in the acupuncture plus herbal medicine group received both treatments. The therapeutic effects of the three groups were evaluated after four weeks of treatment. The primary outcome was the Jankovic rating scale (JRS) score, and the secondary outcome was the blepharospasm disability index (BSDI) score. Results: After four weeks of treatment, the JRS total scores significantly decreased in all three groups versus baseline (P<0.05). A greater reduction in the JRS total score was reported in participants in the acupuncture plus herbal medicine group (P<0.05), but there was no significant difference between the acupuncture group and the herbal medicine group (P>0.05). The acupuncture plus herbal medicine group had a greater decrease in the JRS severity score than the herbal medicine group (P<0.05). The reduction in the JRS frequency score was not significantly different among the three groups (P>0.05). The BSDI scores significantly decreased in all three groups versus baseline (P<0.05), but the reduction in the BSDI score was insignificantly different among the three groups (P>0.05). Conclusion: It is effective in the treatment of BEB either to use acupuncture and Dang Gui Bu Xue Qu Feng Tang alone or in combination. The combination therapy shows a more significant effect than either of the treatment alone.

ABSTRACT

Objective:To investigate the correlation between insulin resistance and alterations in gut microbiota using the animal model of insulin resistance(eLtaS transgenic mice).Methods:Glucose tolerance was measured in eLtaS trans mice and wild-type (WT) mice. Faecal samples of mice were collected for metagenomics and 16S rDNA sequencing. Alterations of gut microbiota in eLtaS trans mice were further analyzed. Faeces from eLtaS trans mice were transplanted into WT mice by " dirty cage" sharing experiment, and glucose tolerance of mice was measured at different time points after transplantation. Results:Significant differences in composition and function of gut microbiota were observed between eLtaS trans mice and WT mice( P=0.028). Compared with WT mice, the diversity of gut microbiota in eLtaS trans mice increased evidently, moreover the relative abundance of Phylum Firmicutes in eLtaS trans mice significantly increased( P<0.001). However, the relative abundance of Phylum Bacteroides and Phylum Verrucomicrobia decreased visibly( P=0.042, P=0.033). The relative abundance of Akkermansia muciniphila and Parabacterides distasonis related to metabolic diseases decreased significantly in eLtaS trans mice( P=0.033, P=0.013). The gut microbiota of eLtaS trans mice was clearly different from that of WT mice in carbohydrate metabolism, lipid metabolism, biosynthesis of other secondary metabolites, metabolism of other amino acids, energy production and transformation. The glucose tolerance of WT mice was impaired at 7th, 8th and 9th week after faecal transplantation, and recovered at 1 week after cessation of faecal transplantation. Conclusion:Insulin resistance leads to obvious changes of gut microbiota in mice, meanwhile the gut microbiota of insulin resistance mice can further induce impaired glucose tolerance.

ABSTRACT

Objective:To explore the predictive value of preablative stimulated thyroglobulin (psTg) level before 131I treatment on the excellent response (ER) to 131I treatment in patients with functional residual lymph node metastasis without distant metastasis after papillary thyroid carcinoma (PTC) surgery. Methods:From March 2011 to June 2015, 72 patients (22 males, 50 females, age: 14-76 (46.5±14.4) years) who were diagnosed with functional lymph node metastasis without distant metastasis at the time of their first 131I treatment after total thyroid bilobectomy + lymph node dissection performed in the Affiliated Cancer Hospital of Zhengzhou University were retrospectively included, and their serum thyroglobulin antibody (TgAb) levels were normal. Patients were divided into ER group and non-ER group according to the treatment response assessment system. Independent sample t test, χ2 test, and Mann-Whitney U test were used to compare the basic clinical characteristics between the two groups, and then multivariate logistic regression was performed. The ROC curve was employed to evaluate the predictive value of psTg and lymph node size in 131I treatment response. Results:The treatment responses of 44 patients were ER, and those of 28 were non-ER. The differences in gender, age, clinical stage, number and location of postoperative metastatic lymph nodes between ER and non-ER groups were not statistically significant ( t=0.82, χ2 values: 0.16-2.60, all P>0.05), while there were significant differences in American Thyroid Association (ATA) initial risk stratification ( χ2=33.38), lymph node size ( U=296.50) and psTg ( U=111.00, all P<0.001). PsTg (odds ratio ( OR)=0.047, 95% CI: 0.004-0.500, P=0.011) and lymph node size ( OR=0.146, 95% CI: 0.032-0.666, P=0.013) were independent factors affecting ER, whereas ATA initial risk stratification was not an independent factor ( OR=0.266, 95% CI: 0.051-1.390, P=0.116). AUCs for psTg and lymph node size were 0.904 and 0.873, respectively. The cut-off value of psTg was 20.05 μg/L with the sensitivity and specificity of 96.4%(27/28) and 75.0%(33/44) respectively, and lymph node size was 0.75 cm with the sensitivity and specificity of 78.6% (22/28) and 81.8% (36/44) respectively. Conclusion:PsTg can be used to predict 131I outcomes in patients with functional lymph node metastases after PTC, and lymph node size also has effect on ER.

ABSTRACT

Objective:To investigate the clinical efficacy of TiRobot-assisted minimally invasive percutaneous screw fixation for pelvic fractures.Methods:The clinical data of 44 patients with pelvic fracture were retrospectively analyzed who had undergone TiRobot-assisted minimally invasive percutaneous screw fixation from May 2018 to April 2021 at Department of Orthopedic Traumatology, The First Hospital of Jilin University. There were 30 males and 14 females, aged from 11 to 78 years (average, 40.6 years). According to the Tile classification, there were 20 type C1 fractures, 23 type C2 fractures and one type C3 fracture. The time from injury to operation averaged 8.2 days (from 1 to 41 days). The minimally invasive percutaneous screw fixation was assisted by the orthopaedic TiRobot in all patients. Operation time, fluoroscopy time, reduction quality, complications and functional recovery at the final follow-up were recorded and analyzed.Results:A total of 96 screws were implanted in this cohort. The total fluoroscopy time ranged from 17 to 66 s, with an average of 17.8 s for each single screw. The operation time ranged from 50 to 355 min, averaging 179.7 min. According to the Matta criteria, the reduction quality was rated as excellent in 36 cases, as good in 5 and as fair in 3, yielding an excellent and good rate of 93.2%(41/44). All the 44 patients were followed up for 6 to 42 months (average, 20.4 months). The fracture healing time ranged from 2 to 6 months, averaging 3.3 months. The Majeed scores at the final follow-up ranged from 51 to 100 points (average, 83.7 points); there were 28 excellent, 8 good, 7 fair and one poor cases, giving an excellent to good rate of 81.8% (36/44). Follow-up found no such complications as iatrogenic neurovascular injury, incision infection, malunion, implant loosening or fracture re-displacement in all the 44 patients.Conclusion:TiRobot-assisted minimally invasive internal fixation can result in fine clinical efficacy for pelvic fractures, showing advantages of accuracy, minimal invasion and safety.

ABSTRACT

Objective:To study the clinical characteristics of congenital tuberculosis (CTB).Methods:From June 2016 to February 2021, the clinical data of infants with CTB admitted to the neonatal department of our hospital were retrospectively analyzed, including their clinical characteristics, diagnosis, treatment and prognosis.Results:A total of 7 infants with CTB were enrolled into the study. 4 mothers had in vitro fertilization embryo transfer (IVF-ET) due to tubal obstruction and 2 mothers who were diagnosed of tubal tuberculosis. The 7 infants included 1 male and 6 female, 6 preterm and 1 full-term. The median age of onset was 18 d (7~30 d).All of the 7 infants had fever, 6 had shortness of breath and poor response, 5 had apnea, 3 were coughing, 1 showed pale skin colour, 1 had bilateral rales in the lung, 6 had hepatomegaly, 3 splenomegaly and 1 lymphadenopathy. Chest X-ray showed patchy exudation in 3 infants, miliary pattern of opacification in 2 infants, patchy opacification in 1 infant, bilateral increased lung markings in 1 infant. The positive rate of acid-fast bacilli (AFB) was 50% in all sputum samples. Specimens from glottic and subglottic area showed higher positive rate than oropharyngeal specimen. PCR MTB-DNA tests of sputum samples were positive in all 7 cases. 1 infant received invasive respiratory support for 1 d and died after discharge. 2 infants improved significantly after initial treatment, received 1~2 months of anti-TB therapy outside the hospital and died of severe respiratory failure. Of the 4 infants survived, 1 was cured and 3 significantly improved.Conclusions:Mothers with tubal tuberculosis receiving IVF-ET may cause high risk of CTB. Sputum AFB test and sputum PCR MTB-DNA test are preferred diagnostic tests. Genetic test of drug-resistant TB may guide clinical drug use. Glottic or deeper throat specimens can increase the positive rate.

ABSTRACT

Objective:To explore new methods to assist the diagnosis of glucose transporter type 1 deficiency syndrome (GLUT1-DS).Methods:Sixteen children with epilepsy and/or movement disorder carrying the SLC2A1 mutation who admitted to Department of Pediatrics, the First Medical Center, Chinese People′s Liberation Army General Hospital and Department of Nutrition, Shanghai Deji Hospital from October 2019 to October 2020 were retrospectively analyzed.GLUT1-DS was diagnosed based on clinical phenotype, glucose level in CSF and/or genetic testing results.Forty-four healthy children who underwent physical examination in the First Medical Center, Chinese People′s Liberation Army General Hospital during the same period were selected as healthy control group.Glucose transporter 1 (GLUT1) level on the membrane surface of peripheral red blood cells and erythrocyte glucose uptake rate were measured by flow cytometry and glucose oxidase method, respectively.Their differences between groups were compared by the rank sum test.The receiver operating cha-racteristic (ROC) curve was plotted to assess their diagnostic value. Results:Sixteen children were diagnosed as GLUT1-DS.GLUT1 levels of 16 children with GLUT1-DS were significantly lower than those of healthy control group [17.96% (13.43%, 22.12%) vs.27.93% (24.76%, 34.30%), Z=5.249, P<0.001]. Area under curve (AUC) was 0.946, and weighted Kappa was 0.791 ( P<0.001). The erythrocyte glucose uptake was measured in 12 children with GLUT1-DS, which was significantly lower than that of healthy control group [23.14% (14.80%, 26.45%) vs.27.40% (24.61%, 32.82%), Z=2.366, P=0.018]. AUC and weighted Kappa were 0.724 and 0.344, respectively ( P<0.001), showing a poor consistency. Conclusions:GLUT1 level on the surface of human erythrocyte membrane measured by flow cytometry may be a new method to assist the diagnosis of GLUT1-DS.The erythrocyte glucose uptake rate test requires stricter experimental conditions and needs further investigation.

ABSTRACT

@#Objective    To assess the efficacy of lymphadenectomy in different regions for esophageal squamous cell carcinomas located differently according to the lymph node grouping by Chinese expert consensus. Methods    The medical records of 1 061 patients (886 males and 175 females with a median age of 60 (54, 65) years with esophageal cancer from March 2011 to December 2017 in our hospital were retrospectively analyzed. According to the pathological report, the lymph nodes were regrouped according to the Chinese lymph nodes grouping standard of esophageal cancer. The metastasis rate of each group of lymph nodes, the 5-year survival rate of metastatic patients and efficacy index (EI) were calculated. Results    The upper thoracic esophageal cancer mainly metastasized to the lymph nodes of C201-203 groups. The middle and lower thoracic tumors mainly metastasized to the lymph nodes of C205-207 groups. The lower thoracic tumor had a higher rate of metastasis to the abdominal lymph nodes. According to the metastasis rate, the mediastinal lymph nodes were divided into three regions: an upper mediastinum (C201-204), a middle mediastinum (C205-206), and a lower mediastinum (C207-209). The EIs of lymph nodes of C201-203 and C205-207 groups were higher. For patients with C201-207 groups metastasis, the 5-year survival rates ranged from 13.39% to 21.60%. For patients with positive lymph nodes in each region, tumors at different primary locations had no statistical difference in long-term survival (P>0.05). Patients with lymph nodes of C205 group in the upper thoracic tumors had lower EI and those in the middle and lower thoracic tumors had higher EIs. Conclusion    The effect of lymph node dissection in each area varies with the location of the tumor. No matter where the tumor is, it is necessary to dissect the upper mediastinal lymph nodes, especially the lymph nodes adjacent to the left and right recurrent laryngeal nerves. Group C205 should be classified into the lower mediastinal lymph nodes.

ABSTRACT

Cannabis sativa,with a long history of cultivation, is a traditional industrial crop widely used for food, textiles, and me-dicine. This study discussed industrial C. sativa and medicinal C. sativa. According to the characteristics of management policies of C. sativa in different periods, we divided the development stages of C. sativa into three stages and analyzed the changes in breeding and cultivation goals under the influence of policies. Meanwhile, a comprehensive analysis was carried out based on the breeding conditions of industrial C. sativa in China. Because of the vast territory of China, the differences in agricultural planting environment, economic development, and social development in the southern and northern areas result in different used parts of C. sativa. To be speci-fic, flowers and leaves are used in Yunnan, fiber in Heilongjiang, and seeds in Shanxi. The breeding of C. sativa varieties highlights fiber, seeds, or both of them. As the value of cannabidiol is explored, medicinal C. sativa has been approved in recent years. Based on the cultivation characteristics and value of industrial C. sativa, it is proposed that industrial C. sativa has a broad application prospect as an important industrial crop, and the existing products contain almost no tetrahydrocannabinol. The cultivation of C. sativa should be rationally guided to promote the development of the C. sativa industry. Moreover, it is recommended to actively apply advanced breeding techniques such as molecular breeding to overcome the problems of the uncertainty of the existing induced breeding and the excessively long hybrid breeding cycle, and develop high value-added applications such as medicinal products of C. sativa to enhance the exploitation of the economic value of C. sativa.

ABSTRACT

As revealed by the investigation on the name change, biological characteristics, artificial cultivation, and edible history of Polygonatum kingianum var. grandifolium, it was described as a variation pattern of P. kingianum in the Chinese version of Flora of China(1978) and as a variant of P. kingianum in the revised English version of the Flora of China(2000). P. kingianum var. grandifolium, long been consumed as food by local folks, has been widely cultivated in its natural distribution area and circulated as Polygonati Rhizoma in the market. The important biological properties of P. kingianum var. grandifolium make it possess a great potential of being consumed as both medicine and food. The shoots of P. kingianum var. grandifolium sprout immediately out of the ground after seed germination and a new seedling will be formed at the same year, implying that its seedling cultivation period is at least two years shorter than that of P. cyrtonema. It can sprout more than twice a year, and the adult plants always remain evergreen, thereby obtaining higher biomass. Its rhizome biomass can be more than one time higher than that of P. cyrtonema. With reference to the diploid P. cyrtonema, flow cytometry revealed the polyploid and aneuploid forms in natural populations, which were tall and light-adapted with large underground rhizome. It can grow normally under the forest canopy and in the open field. Furthermore, P. kingianum var. grandifolium has important theoretical values for the study of ploidy variation, bud dormancy mechanism, etc.

ABSTRACT

Objective: To observe the intervention effect of auricular point sticking on dry eye in myopia patients after small-incision lenticule extraction (SMILE) surgery.Methods: This was a prospective randomized controlled study conducted among the myopia patients who received SMILE surgery at Eye and ENT Hospital of Fudan University. The post-SMILE operation patients who screened by the inclusion and exclusion criteria were randomized into a control group and a treatment group. Patients in the control group were given 0.1% fluorometholone and 0.5% carboxymethylcellulose sodium eye drops, while the treatment group was given additional unilateral auricular point sticking for 1 month. The patients were estimated using ocular surface disease index (OSDI), Schirmer tear test-1 (STT-1), tear film break-up time (TF-BUT), corneal fluorescein staining (CFS) score, corneal sensitivity (CS) and visual quality (VQ) at 1 d, 1 week and 1 month after surgery; the changes in anxiety and depression were also observed in the patients. Results: Compared with the first day after operation, CS in the nasal region was improved in the treatment group, and the VQ score increased in the control group patients at 1 week after operation (both P<0.05); at 1 month after operation, the TF-BUT increased, CFS score decreased, CS in the central and nasal regions increased (all P<0.05), and VQ score increased (P<0.01) in the treatment group, and the CS in the central, upper, lower and nasal regions were improved (all P<0.05), and VQ score increased (P<0.01) in the control group. The between-group comparison showed that the differences in the change of TF-BUT were statistically significant at 1 week and 1 month after surgery, respectively (both P<0.05). Conclusion: Auricular point sticking therapy can increase the TF-BUT and accelerate the repair of ocular surface function in post-SMILE patients.

ABSTRACT

Objective:To observe heart rate circadian rhythm in patients with chronic kidney disease (CKD) stage 5 and to analyze the effects of parathyroidectomy (PTX) on heart rate circadian rhythm in severe secondary hyperparathyroidism (SHPT) patients.Methods:A cross-sectional observation was performed in 213 patients with CKD stage 5 and 96 controls, and the patients were divided into those with severe SHPT (PTX group, n=70) and without severe SHPT (non-PTX group, n=143). Forty-six PTX patients were followed up prospectively. The baseline data were compared among these groups. Holter electrocardiogram was performed for each participant. Non-dipping heart rate was defined as night/day heart rate ratio greater than 0.9. Multiple linear regression analysis was used to analyze the related factors of heart rate circadian rhythm in patients with CKD stage 5. Results:The 24-hour, daytime and nighttime mean heart rate in patients with CKD stage 5 were all higher than those in controls, especially in PTX group (all P<0.05). The night/day heart rate ratios of controls and CKD stage 5 patients were (0.81±0.08) and (0.91±0.08) respectively ( P<0.01). Correlation analysis showed 24-hour and daytime or nighttime mean heart rate in patients with CKD stage 5 were positively correlated with serum levels of phosphorus and ln(alkaline phosphatase), while nighttime mean heart rate and night/day heart rate ratio were positively related with serum intact parathyroid hormone level. After adjusting with postoperative follow-up period (median time: 10.9 months), 24-hour and nighttime mean heart rate, and night/day heart rate ratio in PTX patients all decreased significantly (all P<0.01). Conclusions:Heart rate is increased and circadian rhythm is abnormal in patients with CKD stage 5, which are related with mineral and bone disorder. PTX significantly decreases 24-hour and nighttime mean heart rate in severe SHPT patients, and improves the heart rate circadian rhythm.

ABSTRACT

Objective:To investigate the risk factors of rotator cuff tears combined with long head of bicep tendon (LHBT) lesion and its effects on preoperative function.Methods:From January 2016 to January 2020, there were 680 patients with rotator cuff tears, including 260 males and 420 females, were included. The average age was 56.1±8.7 (range 27-74 years). There were 250 cases on the left side and 430 cases on the right side. There were 436 cases on the main side, while 274 cases had definite trauma before operation. The following were the Post rotator cuff tears classification, 133 cases in partial injury, 473 cases in small and medium size of rotator cuff tears, 74 cases in large and massive size of rotator cuff tears. The Habermayer-Walch classification of LHBT lesions was as following, 302 cases in type 0 (normal), 216 cases in type 1 (tendonitis), 29 cases in type 2 (dislocation and subluxation), 104 cases in type 3 (partial tear), 20 cases in type 4 (complete tear) and 9 cases in type 5 (SLAP injury above type II). The patient with rotator cuff tears were divided into partial tears group, medium and small tears group, large and massive tears group according to the classification of Post. The visual analogue scale (VAS), simple shoulder test (SST), Constant-Murley function score and the score of the University of California Los Angeles (UCLA) were recorded. The differences in age, sex, main side, trauma and LHBT lesion in patients with three types of rotator cuff tears were analyzed. The preoperative pain and function scores of patients with or without LHBT lesions in various rotator cuff tears were compared among the groups by t-test. The age, sex, main side, with trauma or not, and the classification of rotator cuff tears were analyzed by Logistic regression to investigate the risk factors of patients with rotator cuff tears with LHBT lesions. Results:There were 378 cases (55.6%) with LHBT lesions in 680 patients with rotator cuff tears, including 216 cases of tendinitis (57.1%), 104 cases of partial tear (27.5%), 29 cases of dislocation and subluxation (7.7%), 20 cases of complete tear (5.3%) and 9 cases of SLAP injury (2.4%). The incidence of partial injury, small and medium injury, large and massive rotator cuff injury combined with LHBT lesions were 35.3% (47/133), 57.5% (272/473) and 79.7% (59/74) respectively. The preoperative VAS score, UCLA score, Constant-Murley score and SST score were 5.20±1.52, 14.81±4.12, 41.45±4.93 and 4.56±1.96 respectively in rotator cuff tears group and 5.29±1.65, 14.34±4.01, 41.60±5.88, 4.47±1.97 in LHBT group ( P>0.05). In the partial rotator cuff tears group, the VAS score was 5.16±1.41 in patients with simple rotator cuff tears and 5.68±1.46 in patients with LHBT lesion ( t=2.004, P=0.047). Regression analysis showed that age ≥60 years and rotator cuff tears degree were the risk factors for rotator cuff tears with LHBT ( P<0.001). Conclusion:It is common for patients to have rotator cuff tears with LHBT lesions. The more severe the rotator cuff tears are, the higher the incidence of LHBT lesions will be. Patients with rotator cuff tears aged 60 and above are more likely to have LHBT lesions. However, the complications of LHBT could not affect the preoperative pain and functional scores of patients with rotator cuff tears.

ABSTRACT

Objective:To evaluate the efficacy of posterior subtotal vertebrectomy in the treatment of thoracolumbar vertebral refractures after vertebroplasty.Methods:A retrospective analysis was conducted in the 28 patients with refracture after percutaneous vertebroplasty(PVP) or percutaneous kyphoplasty(PKP) who had been treated at Department of Spinal Surgery, Henan Provincial People's Hospital from June 2017 to October 2019. They were 7 males and 21 females, with an average age of 62.4 years(from 61 to 76 years). A total of 28 vertebrae were involved, including 5 T11s, 9 T12s, 11 L1s and 3 L2s. Their previous operations were PKP in 17 cases and PVP in 11. After the spinous process, vertebral plate, articular process and transverse process were resected by posterior approach, the vertebral body, bone cement and upper and lower intervertebral discs were partially resected by trans-vertebral lateral approach. At the same time, nerve decompression was performed. Finally, the inter-vertebral support was fixated followed by the posterior screw-rod orthopedic fixation. The operation time and intraoperative bleeding volume were recorded. The cobb angles of kyphosis were compared on the X-ray films of the whole spine between preoperation and the last follow-up to evaluate correction. Functional improvement of the spine was evaluated by comparison of the visual analogue scale (VAS) and JOA(Japanese Orthopedics Association) scores between preoperation and the last follow-up.Results:The operation time averaged 182.1 min and intraoperative bleeding volume 996.2 mL. All the 28 patients were followed up for 8 to 29 months (mean, 19.8 months). No obvious neurological lesions or other serious complications were observed. The cobb angle was improved from preoperative 41.3°±10.3° to 6.4°±2.5° at the last follow-up, the VAS score from preoperative 7.3±1.8 to 2.5±1.0 at the last follow-up, and the JOA score from preoperative 8.4±2.3 to 21.3±2.5 at the last follow-up, showing a significant difference in all the comparisons ( P<0.05). Conclusion:The posterior subtotal vertebrectomy is effective for thoracolumbar vertebral refractures after vertebroplasty because it can remove bone cement, decompress the spinal canal, fuse the inter-vertebral graft and reconstruct the spinal stability in one stage.

ABSTRACT

Objective:Bioinformatics was used to analyze the gene expression profile of renal chromophobe cell carcinoma (RCCC) to find out the key genes of RCCC.Methods:Chromophobe renal cell carcinoma gene chip data GSE15641 and GSE11151 were downloaded from the GEO database. Using R software packages such as " Affy" and " limma" in R software to screen differentially expressed genes, combining with David and STRING online bioinformatics tools to analyze the regulatory network of differentially expressed genes and construct protein-protein interaction (PPI) network, the Hub gene was screened through the Cytohubba plug-in of Cytoscape software.Results:A total of 261 differentially expressed genes were screened, including 194 down-regulated genes and 67 up-regulated genes. Gene enrichment (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed to explore their biological functions. In GO enrichment analysis, biological processes were mainly enriched in cell secretion, gluconeogenesis and cell proliferation regulation; in cell composition, they were mainly enriched in exosomes, plasma membranes and their components; in molecular function, they were mainly enriched in heparin binding; in KEGG pathway analysis, they were mainly enriched in metabolic pathway, antibody biosynthesis pathway and renin angiotensin system pathway. PPI network was constructed by using online bioinformatics tools. The top 10 Hub genes were screened by using cytohubba plug-in in Cytoscape software, which were pipecolic acid and sarcosine oxidase (PIPOX), hydroxyacid oxidase 2 (HAO2), kynurenine 3-monooxygenase (KMO), solute carrier family 2 member 2 (SLC2A2), formimidoyltransferase cyclodeaminase (FTCD), angiogenin (ANG), APOBEC1 complementation factor (A1CF), aldehyde dehydrogenase 8 family member A1 (ALDH8A1), vitamin D binding protein (GC), histidine rich glycoprotein (HRG).Conclusions:Bioinformatics analysis of differentially expressed genes in renal chromophobe cell carcinoma can effectively explore the interaction information of these differentially expressed genes, and provide new ideas for the treatment of renal chromophobe cell carcinoma.

ABSTRACT

Objective:To determine the prognostic values of clinical and laboratory features at the time of presentation on renal survival of patients with myeloperoxidase (MPO)-antineutrophil cytoplasmic antibody(ANCA)-associated glomerulonephritis (MPO-ANCA-GN).Methods:A total of 172 patients with MPO-ANCA-GN and hospitalized at the First Affiliated Hospital of Nanjing Medical University from January 2005 to December 2018 were enrolled. The baseline clinical characteristics and renal biopsy pathological data were analyzed, and the renal prognosis was followed up. The clinical and pathological characteristics of different renal prognosis in all patients and 112 patients who underwent renal biopsy were analyzed, and the related factors affecting renal survival were further discussed.Results:Among these 172 patients, 81 were males and 91 were females. The median serum creatinine at diagnosis was 343.7(174.2, 606.6) μmol/L and the median estimated glomerular filtration rate (eGFR) was 15.81(7.61, 38.04) ml·min -1·(1.73 m 2) -1. In total, 76 patients (44.2%) received initial renal replacement therapy (RRT). During a median follow-up duration of 20(3, 60) months, 73 patients (42.4%) progressed to end-stage renal disease (ESRD) and required dialysis, including 6 (8.2%) patients who entered RRT during follow-up and 67 (91.8%) patients who received RRT at the beginning. Among the 112 patients who underwent renal biopsy, the proportion of patients who progressed to ESRD in the sclerotic group was the highest (15/25, 60.0%). The baseline serum creatinine level ( P<0.001), urine red blood cell count ( P=0.012) and the proportion of glomerular sclerosis ( P=0.002) in the non-dialysis dependent group were significantly lower than those in the dialysis dependent group, while the levels of eGFR ( P<0.001), serum albumin ( P=0.002) and hemoglobin ( P<0.001) were higher than those of the dialysis-dependent group. Kaplan-Meier survival analysis showed that the renal survival rate of the focal group was the highest ( χ2=19.488, P<0.001, log-rank test), while the renal survival rate of the sclerotic group was significantly lower than that of the crescentic group ( χ2=5.655, P=0.017); higher levels of serum creatinine (>320 μmol/L, χ2=77.229, P<0.001) and urine red blood cell count (>300 cells/μl, χ2=8.511, P=0.004), lower levels of rheumatoid factor (<20 IU/ml, χ2=8.610, P=0.003), serum albumin (<30 g/L, χ2=11.060, P=0.001) and hemoglobin (<90 g/L, χ2=21.921, P<0.001) were associated with lower renal survival rate; in terms of treatment, the renal survival rate of the glucocorticoids plus mycophenolate mofetil group was significantly higher than that of the glucocorticoids plus cyclophosphamide ( χ2=5.056, P=0.025) or the glucocorticoids alone group ( χ2=16.459, P<0.001). Multivariate Cox regression showed that baseline serum creatinine >320 μmol/L ( HR=8.803, 95% CI 3.087-25.106, P<0.001) and serum albumin <30 g/L ( HR=2.566, 95% CI 1.246-5.281, P=0.011) were the related factors affecting renal survival. Conclusion:Serum creatinine and albumin levels of MPO-ANCA-GN patients at diagnosis may be the related factors that affect the patient's renal prognosis.

ABSTRACT

Objective:To investigate the predictive value of abnormal heart rate circadian rhythm for all-cause mortality in stage 5 chronic kidney disease (CKD 5) patients.Methods:The retrospective study was performed in CKD 5 patients enrolled from the First Affiliated Hospital of Nanjing Medical University (Jiangsu Province Hospital) and the Affiliated BenQ Hospital of Nanjing Medical University from February, 2011 to December, 2019. A total of 159 healthy volunteers were enrolled as the healthy control group during the same period. The circadian rhythm of heart rate was monitored by 24-hour Holter. Related indices (including 24-hour, daytime and nighttime mean heart rate, night/day heart rate ratio, 24-hour maximum heart rate, 24-hour minimum heart rate and difference between maximum and minimum of 24-hour heart rate) were calculated. Non-dipping heart rate was defined as night/day heart rate ratio greater than 0.9. Cox regression model was used to analyze the risk factors of all-cause mortality in CKD 5 patients. Kaplan-Meier survival curve and Log-rank test were used to compare the differences of cumulative mortality between high ratio group (night/day heart rate ratio>0.91) and low ratio group (night/day heart rate ratio≤0.91). The nonlinear relationship between night/day heart rate ratio and all-cause mortality was analyzed by restricted cubic spline plot. Time-dependent receiver operating characteristic (ROC) curve was used to analyze the predictive value of night/day heart rate ratio for all-cause mortality in CKD 5 patients.Results:A total of 159 healthy volunteers and 221 CKD 5 patients were included in this study. There were 123 males (55.66%) and the age was (52.72±13.13) years old in CKD 5 patients. The total median follow-up time was 50.0 months. Compared with controls, 24-hour, nighttime mean heart rate, 24-hour minimum heart rate in CKD 5 patients were increased (all P<0.05), furthermore, the night/day heart rate ratio was higher [(0.91±0.09) vs (0.81±0.08), P<0.001], showing "non-dipping heart rate". However, the 24-hour maximum heart rate and the difference between maximum and minimum of 24-hour heart rate in CKD 5 patients were lower than controls (both P<0.05). Multivariate Cox regression analysis showed that the increased night/day heart rate ratio (per 0.1 increase, HR=1.557, 95% CI 1.073-2.258, P=0.020) was an independent influencing factor for all-cause mortality in CKD 5 patients. Kaplan-Meier survival curve analysis showed that the cumulative mortality of the high ratio group was significantly increased than that of the low ratio group (Log-rank test χ 2=7.232, P=0.007). From the restricted cubic spline plot, there was a linear effect between night/day heart rate ratio and all-cause mortality ( P=0.141), and when night/day heart rate ratio was above 0.91, the risk of all-cause mortality was significantly increased in CKD 5 patients. According to time-dependent ROC curve, the accuracy of night/day heart rate ratio in predicting all-cause mortality was 70.90% even when the survival time was up to 70.0 months. Conclusions:The circadian rhythm of heart rate in CKD 5 patients displays "non-dipping" state. High night/day heart rate ratio is an independent influencing factor for all-cause mortality in CKD 5 patients.
