ABSTRACT

School-age children are in a specific development stage corresponding to juvenility, when the white matter of the brain experiences ongoing maturation. Diffusion-weighted magnetic resonance imaging (DWI), especially diffusion tensor imaging (DTI), is extensively used to characterize the maturation by assessing white matter properties in vivo. In the analysis of DWI data, spatial normalization is crucial for conducting inter-subject analyses or linking the individual space with the reference space. Using tensor-based registration with an appropriate diffusion tensor template presents high accuracy regarding spatial normalization. However, there is a lack of a standardized diffusion tensor template dedicated to school-age children with ongoing brain development. Here, we established the school-age children diffusion tensor (SACT) template by optimizing tensor reorientation on high-quality DTI data from a large sample of cognitively normal participants aged 6-12 years. With an age-balanced design, the SACT template represented the entire age range well by showing high similarity to the age-specific templates. Compared with the tensor template of adults, the SACT template revealed significantly higher spatial normalization accuracy and inter-subject coherence upon evaluation of subjects in two different datasets of school-age children. A practical application regarding the age associations with the normalized DTI-derived data was conducted to further compare the SACT template and the adult template. Although similar spatial patterns were found, the SACT template showed significant effects on the distributions of the statistical results, which may be related to the performance of spatial normalization. Looking forward, the SACT template could contribute to future studies of white matter development in both healthy and clinical populations. The SACT template is publicly available now ( https://figshare.com/articles/dataset/SACT_template/14071283 ).

ABSTRACT

At present, endometriosis remains a worldwide health burden, with the main symptoms of dysmenorrhea, chronic pelvic pain, and infertility, markedly reducing the quality of life (de Ziegler et al., 2010). Although there is no proof that the disease is associated with high mortality, this disorder can significantly contribute to the deterioration of women's general well-being (McPeak et al., 2018). The main current treatment for endometriosis is surgery to remove endometriotic lesions; however, the recurrence rate following surgical treatment is as high as 21.5% at two years and 40.0%‍-‍50.0% at five years post-surgery (Koga et al., 2015). To prevent recurrence, adjuvant treatment with drugs after surgery is recommended to prolong relapse-free intervals. However, it is inconvenient for patients to continuously use such medications in terms of adverse effects and cost (Turk, 2002).

ABSTRACT

OBJECTIVE@#To observe clinical efficacy of chiropractic manipulation in the treatment of degenerative scoliosis (DS).@*METHODS@#From June 2017 to September 2019, 120 patients with degenerative scoliosis were randomly divided into treatment group (60 cases) and control group(60 cases). The patients in treatment group were treated with chiropractic manipulation once every other day for 4 weeks. The patients in control group were treated with eperisone hydrochloride tablets combined with thoracolumbar orthopedic(TSLO)brace, oral eperisone hydrochloride tablets 50 mg three times a day, wearing TSLO brace for not less than 8 hours a day. The course of treatment was 4 weeks. After the patients were selected into the group, visual analogue scale (VAS) and Oswestry Disability Index (ODI) were recorded before treatment, 1, 2, 3, 4 weeks after treatment and 1 month after treatment. The full length X-ray of the spine was taken before and 4 weeks after treatment, and the scoliosis Cobb angle, sagittal vertical axis (SVA) and lumbar lordosis (LL) were measured and compared. The adverse reactions during the treatment were recorded.@*RESULTS@#There were significant differences in VAS and ODI between two groups at each time point after treatment (P<0.001), VAS and ODI at 2 weeks after treatment (PVAS=0.025, PODI=0.032) and 3 weeks after treatment(PVAS=0.040, PODI=0.044) in treatment group were significantly different from those in control group, but there was no significant difference in VAS and ODI at other time points between treatment group and control group (P>0.05). There was significant difference in Cobb angle between treatment group(P=0.010) and control group(P=0.017) after treatment, but there was no significant difference in LL and SVA between treatment group and control group. There was no significant difference in Cobb angle, LL and SVA between two groups before and after treatment. During the treatment, there were 4 mild adverse reactions in the control group and no adverse reactions in the treatment group.@*CONCLUSION@#Chiropractic manipulation can effectively relieve pain and improve lumbar function in patients with degenerative scoliosis. The onset of action is faster than that oral eperisone hydrochloride tablets combined with TSLO brace, and it has better safety and can improve Cobb angle of patients with degenerative scoliosis.

ABSTRACT

This paper was aimed to investigate the effect of voluntary wheel running exercise on depression-like behavior induced by chronic water immersion restraint stress (CWIRS) and the underlying mechanism. Sprague-Dawley (SD) rats received CWIRS to induce depression-like behavior and 4-week voluntary wheel running exercise. Meanwhile, the rats were treated with lipopolysaccharide (LPS) or STAT3 over-expression vector (pcDNA-STAT3) by intracerebroventricular injection. Behavioral tests were used to detect depression-like behavior. ELISA assay was used to detect levels of various inflammatory factors in the rat hippocampus. Western blot was used to detect protein expression levels of ionized calcium binding adaptor molecule 1 (Iba1), inducible nitric oxide synthase (iNOS), arginase 1 (Arg1), phosphorylated STAT3 (p-STAT3) and total STAT3 (t-STAT3). The results showed that, compared with stress group, stress + exercise group exhibited improved depression-like behavior, decreased interleukin-1β (IL-1β) and IL-6 levels, increased IL-4 and IL-10 levels, down-regulated Iba-1 and iNOS protein expression levels, up-regulated Arg1 protein expression level, and decreased p-STAT3/t-STAT3 ratio in hippocampal tissue. LPS reversed the improving effect of voluntary wheel running exercise on depression-like behavior in rats, and the over-expression of STAT3 reversed the promoting effects of voluntary wheel running on M2 polarization of microglial cells in rat hippocampus and depression-like behavior. These results suggest that voluntary wheel running ameliorates the depression-like behavior induced by CWIRS in rats, and the mechanism may be related to regulating hippocampal microglia polarization via STAT3 signaling pathway.

ABSTRACT

ObjectiveTo investigate the effect of the Yap1 gene and tanshinone ⅡA on the proliferation, migration, and invasion abilities of Huh-7 hepatoma cells. MethodsA total of 10 pairs of human hepatocellular carcinoma (HCC) samples and adjacent tissue samples were collected in Zhongnan Hospital of Wuhan University from June 1 to December 1, 2019. Quantitative real-time PCR and Western blotting were used to measure the expression of the Yap1 gene and phenotype-related molecules. MTT cell proliferation detection reagent was used to measure the inhibition rate of cell proliferation after the treatment with different concentrations of tanshinone ⅡA. Western blotting was used to measure the changes in the expression of apoptosis-and migration-related markers after different interventions. Flow cytometry and Transwell assay were used to measure apoptosis and cell migration and invasion abilities. The data of 375 cases of liver cancer and 50 cases of relatively normal liver tissue samples were downloaded from The Cancer Genome Atlas, including clinicopathological information. The t-test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. ResultsIn 8 of the 10 pairs of HCC samples and adjacent tissue samples, HCC samples had significantly higher expression of Yap1 than the adjacent tissue samples. Compared with the normal human liver epithelial cells L02, the Huh-7 and HCCL-M3 hepatoma cells had a significant increase in the expression of Yap1. The silencing efficiency of si-Yap1-3 transfection reached 87.004% at the protein level. MTT results showed that tanshinone ⅡA effectively inhibited the proliferation of Huh-7 cells, with a half inhibitory concentration of 8.683 μmol/L. After the cells were treated with si-Yap1-3 and tanshinone ⅡA, there was an increase in the expression of the downstream marker for proliferation and migration E-cadherin and a reduction in the expression of vimentin, and the results of Transwell assay showed that compared with the si-NC group, the tanshinone ⅡA+si-Yap1-3 group had significant reductions in the migration and invasion abilities of Huh-7 cells (migration: 43.19±2.88 vs 132.20±10.03, t=8.527, P=0.001; invasion: 53.95±4.20 vs 179.10±11.11, t=4.484, P=0.011). The group treated with si-Yap1-3 and tanshinone ⅡA had an increase in the expression of the apoptosis-related marker Bax and a reduction in the expression of Bcl-2, as well as a significantly higher early apoptosis rate than the si-NC group (2598% vs 9.21%, χ2=4.078, P<0.05). ConclusionOncogene Yap1 silencing combined with tanshinone ⅡA can promote the apoptosis of Huh-7 hepatoma cells and inhibit their migration and invasion, which can provide certain guiding significance for clinical medication.

ABSTRACT

Objective:To explore the feasibility of emergency video call system in remote guidance of non-medical volunteers to implement single person cardiopulmonary resuscitation (CPR).Methods:A scenario of sudden cardiac arrest with a bystander in a public place was created at Clinical Skill Training Center. 60 non-medical volunteers were randomly (ramdom number) divided into video group ( n = 40) and audio group ( n = 20). Volunteers in video group were remote instructed with the smart phone application software (APP) of Emergency Video Call System to implement CPR; the audio group receives remote voice guidance for CPR with a smart phone. The pressing depth, pressing frequency, volume of ventilation and the time of the first compression were compared between the two groups. The video group was divided into 5 subgroups to compare the cardiopulmonary resuscitation effect of 5 different models of smart phones. Ten CPR cycles were observed in each group. Results:the accuracy rate of pressing position in the video group was significantly higher than that in the audio group (91.5% vs 71.35%, P < 0.05); the proportion of pressing depth in the range of 5-6 cm was significantly higher than that in the audio group (62.79% vs. 44.73%, P < 0.05); the average pressing frequency was 100-120 times / min (70% vs. 52%, P < 0.05); the ventilation volume was 500-600 mL / time (18.25% vs. 10.75%, P < 0.05); The proportion of ventilation volume greater than 500ml / min was higher than that of audio group (64.88% vs. 43%, P < 0.05). The first pressing time was longer in the video group than in the audio group (131 s vs. 106 s, P < 0.05). There was no significant difference in the first ventilation time between the two groups (148 s vs. 144 s, P > 0.05). The total pressing pause time in video group was less than that in audio group (122.4 s vs. 164.2 s, P < 0.05). There was no significant difference in the above indicators among the five different models of smart phones in the video group ( P > 0.05). Conclusions:compared with audio remote guidance, video emergency system has obvious advantages in the accuracy of pressing position, pressing depth, pressing frequency, ventilation volume and pressing pause time, but the first pressing time is slightly longer than that of audio group. The popularization and application of the video system is supposed to improve the CPR quality and recovery success rate of non-medical personnel, and facilitated to encourage the first witness to implement CPR.

ABSTRACT

Craniopharyngioma mainly occurs in children aged 5 to 14 years.It′s one of the most common intracranial tumors for children.Although the overall survival rate of pediatric patients with craniopharyngioma has been significantly improved, the long-term quality of life still couldn′t be missed due to the fact that it could invade the important structures around the sellar area, such as the hypothalamus, pituitary gland, and so on.The downward trend is observed among the 5-, 10- and 20-year overall survival rates.Compared with adult-onset patients, childhood-onset patients are at higher risk of hypothalamic involvement, endocrine dysfunction, obesity, have a lower long-term quality of life.In addition to a variety of physical diseases, pediatric patients with craniopharyngioma after surgery may also develop the psychological diseases.Craniopharyngioma should be recognized as a frequently chronic disease which requires constant monitoring of the consequences and medical resources for treatment in order to provide optimal quality of life for pediatric patients.This article reviews the craniopharyngioma-related researches in recent years on the long-term prognosis of childhood-onset patients.

ABSTRACT

Objective:To explore the safety and effectiveness of modified lower costa surgical approach (mLS) for transversus abdominis plane block (TAPB) combined with rectus sheath block (RSB) in surgical incision peritoneal dialysis catheterization (PDC).Methods:Forty chronic kidney disease of stage 5 patients scheduled for PDC from January to December 2018 in Huadu District People′s Hospital of Guangzhou City were selected. The patients were divided into 3 groups by random digits table method, among whom 13 cases used mLS for TAPB combined with RSB (TAPB combined with RSB group), 13 cases used lateral approach combined with hip approach for TAPB (TAPB group), and 14 cases used local anesthesia (LA group). The mean arterial pressure, heart rate and pain visual analogue score (VAS) at skin incision (T 0), separation of rectus abdominis (T 1), peritoneal dialysis catheter placement (T 2) and suture of skin and subcutaneous tunnel (T 3) were recorded; and the total operation and anesthesia time, cases of rescue anesthesia, surgeon′s satisfaction with anesthesia, surgical and anesthesia related complication were recorded. Results:The VAS from T 0 to T 3 in TAPB combined with RSB group and TAPB group was significantly lower than that in LA group: (1.92 ± 0.95) and (3.00 ± 1.08) scores vs. (5.07 ± 0.62) scores, (1.31 ± 0.63) and (2.54 ± 0.66) scores vs. (3.86 ± 0.77) scores, (0.85 ± 0.69) and (1.77 ± 0.93) scores vs. (3.71 ± 0.61) scores, (1.38 ± 0.77) and (1.38 ± 0.87) scores vs. (3.64 ± 0.17) scores, the VAS of T 1 in TAPB combined with RSB group was significantly lower than that in TAPB group, and there were statistical differences ( P<0.05). There were no statistical differences in mean arterial pressure and heart rate among 3 groups ( P>0.05). The surgeon′s satisfaction with anesthesia from T 0 to T 3 in TAPB combined with RSB group and TAPB group were significantly higher than that in LA group: (3.12 ± 0.76) and (3.11 ± 0.65) scores vs. (2.09 ± 0.61) scores, (3.09 ± 0.82) and (2.68 ± 0.75) scores vs. (1.99 ± 0.66) scores, (3.35 ± 0.82) and (3.31 ± 0.75) scores vs. (2.37 ± 0.73) scores, (3.02 ± 0.82) and (3.01 ± 0.75) scores vs. (2.35 ± 0.63) scores, surgeon′s satisfaction with anesthesia of T 1 in TAPB combined with RSB group was significantly higher than that in TAPB group, and there were statistical differences ( P<0.05). The rescue anesthesia in LA group was in 2 cases. The total operation and anesthesia time in TAPB combined with RSB group was significantly shorter than that in TAPB group and LA group: (45.08 ± 9.62) min vs. (74.46 ± 7.29) and (69.71 ± 13.25) min, that in LA group was significantly shorter than that in TAPB group, and there were statistical differences ( P<0.05).

ABSTRACT

Sterol-regulatory element binding proteins (SREBPs) are the key transcriptional regulators of lipid metabolism. The activation of SREBP requires translocation of the SREBP precursor from the endoplasmic reticulum to the Golgi, where it is sequentially cleaved by site-1 protease (S1P) and site-2 protease and releases a nuclear form to modulate gene expression. To search for new genes regulating cholesterol metabolism, we perform a genome-wide CRISPR/Cas9 knockout screen and find that partner of site-1 protease (POST1), encoded by C12ORF49, is critically involved in the SREBP signaling. Ablation of POST1 decreases the generation of nuclear SREBP and reduces the expression of SREBP target genes. POST1 binds S1P, which is synthesized as an inactive protease (form A) and becomes fully mature via a two-step autocatalytic process involving forms B'/B and C'/C. POST1 promotes the generation of the functional S1P-C'/C from S1P-B'/B (canonical cleavage) and, notably, from S1P-A directly (non-canonical cleavage) as well. This POST1-mediated S1P activation is also essential for the cleavages of other S1P substrates including ATF6, CREB3 family members and the α/β-subunit precursor of N-acetylglucosamine-1-phosphotransferase. Together, we demonstrate that POST1 is a cofactor controlling S1P maturation and plays important roles in lipid homeostasis, unfolded protein response, lipoprotein metabolism and lysosome biogenesis.

ABSTRACT

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

ABSTRACT

Objective:To investigate the plasma expression of D-dimer in patients with colorectal cancer and its correlation with clinicopathological characteristics of patients.Methods:The clinical data of 167 patients with colorectal cancer who were admitted to the First Hospital of Shanxi Medical University from January 2014 to March 2019 was retrospectively analyzed, and 54 patients without malignant tumors in the same period were selected as the control group. The expressions of plasma D-dimer and carcinoembryonic antigen (CEA) were detected by using immunoturbidimetry and electrochemiluminescence. Mann-Whitney U test was used to analyze the relationship between D-dimer expression and clinicopathological characteristics of patients. The relationship between D-dimer and CEA expressions was analyzed by Spearman correlation analysis. Results:The level of D-dimer [median ( P25, P75)] in the colorectal cancer group [323.0 ng/ml (150.0 ng/ml, 631.0 ng/ml)] was higher than that in the control group [142.0 ng/ml (89.3 ng/ml, 232.0 ng/ml)], and the difference was statistically significant ( Z=-4.374, P < 0.05). The level of D-dimer in patients with advanced colorectal cancer [401.0 ng/ml (167.5 ng/ml, 735.5 ng/ml)] was higher than that in patients with early stage [169.5 ng/ml (25.0 ng/ml, 325.3 ng/ml)], the difference was statistically significant ( Z = -4.569, P < 0.05); the level of D-dimer in the deterioration stage after treatment [382.0 ng/ml (175.0 ng/ml, 735.3 ng/ml)] was higher than that in the improvement stage after treatment [250.0 ng/ml (163.0 ng/ml, 391.0 ng/ml)], the difference was statistically significant ( Z = -2.731, P < 0.05); the level of D-dimer before operation [220.0 ng/ml (118.0 ng/ml, 446.5 ng/ml)] was lower than that after operation [320.0 ng/ml (184.5, 489.0 ng/ml)], the difference was statistically significant ( Z = -2.182, P < 0.05). There was a positive correlation between CEA and D-dimer expressions in colorectal cancer patients ( r = 0.509, P < 0.01). Conclusions:Elevated plasma D-dimer level may indicate advanced disease and poor prognosis. The plasma D-dimer level can be used as a predictor of therapeutic effect in patients with colorectal cancer.

ABSTRACT

Objective:To reveal the significance of microRNA 155 (miR-155) level or the suppressor of cytokine signaling 6 (SOCS6) level in distinguishing the differentiating tuberculosis (TB) infection.Methods:A case-control study was conducted. A total of 60 patients were enrolled in the study retrospectively, including 20 patients with active pulmonary tuberculosis, 20 patients with latent tuberculosis and 20 patients with other pulmonary infectious diseases (non-TB infection), who visited The Third Affiliated Hospital of Third Military Medical University from January to June of 2017. The expression level of miR-155 and SOCS6 in peripheral blood mononuclear cells (PBMC) of from these patients were examined by using the quantitative real-time polymerase chain reaction (qPCR) methods. The associated statistics and graphs was utilized to obtain the relationship, which were reflected by the Co-index receiver operating characteristic(ROC) curve or calculating the area under ROC curve (AUC), between the miR-155 and SOCS6 in differentiating tuberculosis infection by using the Logistic Regressive analysis methods, MedCalc and GraphPad Prism 8.0 software.Results:Neither of the three index miR-155 (AUC=0.663, P=0.031), SOCS6 (AUC=0.708, P=0.002) and Co-index (AUC=0.718, P=0.001) was outstanding to distinguish the tuberculosis infection and non-TB infection. Moreover, the miR-155 (AUC=0.867, P<0.001) and Co-index (AUC=0.875, P<0.001) were similar sufficient ( Z=0.142, P=0.887) to distinguish the active and latent infections. The Co-index (AUC=0.923, P<0.001) was better ( Z=2.586, P=0.010) than SOCS6 (AUC=0.723, P=0.007), and similar ( Z=1.585, P=0.113) to miR-155 (AUC=0.835, P<0.001) on the distinguishing active and non-TB infection. Conclusions:By performing the qPCR and the correlation-analysis, miR-155 has been considered as a potential biomarker for differentiating latent tuberculosis infection from active tuberculosis infection. Conjoint analysis of miR-155 and SOCS6 benefits the distinguishing active TB infection from other pulmonary infectious diseases.

ABSTRACT

Objective:To explore the efficacy of neurolysis or nerve grafting in the treatment of the conducting neuroma of Narakas II obstetric brachial plexus palsy (OBPP), and provide the reference basis for choosing an optimal method.Methods:From January, 2009 to December, 2014, 32 patients undergoing surgical treatment due to Narakas II OBPP were included in this study. Neurolysis was performed in 15 patients, and the procedure of nerve grafting was performed in 17 patients. The general information included gender, age, birth weight, injury cause, etc. were recorded and compared to each other between 2 groups. A followed-up study had been conducting after surgery, the functional rating systems of Gilbert and Raimondi were used for quantitative comparison between preoperative function and postoperative function of shoulder joint, elbow joint and hand. In addition, the differences of the measurement data were compared with the single factor analysis of variance and paired t-test by using SPSS 22.0 statistical software. When P<0.05, it was considered statistically significant. Results:There was no statistically significant difference in the baseline information between 2 groups ( P>0.05). The average time of follow-up was 58.44 (48-96) months. And the fourth year' average score of shoulder joint, elbow joint, hand of the neurolysis group improved from preoperative (1.07±0.85) , (2.07±0.77) and (3.47±0.62) score to (3.00±0.73), (4.13±0.62) and (4.53±0.72) score ( P<0.05), and the nerve grafting group rose from an average of (0.76±0.73), (1.71±0.46) and (3.71±0.67) score to (3.24±0.55), (4.29±0.46) and (4.65±0.48) score ( P<0.05). But the different score between 2 groups was no statistically significant ( P>0.05), respectively. In addition, the proportion of the patients who needed the secondary operation about functional reconstruction in the neurolysis group and the nerve grafting group was 73.33% and 35.29% respectively, besides the proportion of the shoulder joint and elbow joint in the surgical sites accounted for 82.35%, 17.65% respectively. Conclusion:Nerve grafting is a better choice for the treatment of conducting neuroma of Narakas II OBPP at present.

ABSTRACT

Objective:To have a better understanding of congenital leukemia by summarizing its clinical features and prognosis.Methods:This study retrospectively recruited 10 neonates with congenital leukemia treated in Beijing Children's Hospital, Capital Medical University from January 2006 to December 2018. Clinical data including clinical manifestations, laboratory examinations, treatment and follow-up were described.Results:The 10 patients consisted of six boys and four girls. In all cases, symptoms presented within 11 d after birth. The admission complaints were jaundice ( n=4), polypnea ( n=3), fever ( n=2) and rash ( n=2). Physical examinations of the 10 patients showed eight with splenomegaly, seven with hepatomegaly and seven with petechia/skin rash. All patients had significantly increased white blood cell count (from 45.8×10 9/L to 553.0×10 9/L), complicated by different degrees of anemia and thrombocytopenia. By bone marrow biopsy, two cases were diagnosed as acute lymphoblastic leukemia and the other eight cases as acute myeloid leukemia. All cases refused chemotherapy on the preliminary diagnosis. Three cases lost follow-up and six died within two months after discharge requested by their parents. One baby had spontaneous remission, but relapsed two years later. Complete remission was achieved after strict management and no relapse was reported until ten years old. Conclusions:Congenital leukemia is a severe condition with high mortality. Some cases may achieve spontaneous remission, but long-term follow-up is needed.

ABSTRACT

Objective:To compare and analyze the clinicopathological data of elderly patients with versus without hepatitis B virus(HBV)antigen deposition in renal tissue, and to investigate the clinicopathological features in elderly patients with HBV associated nephritis(HBV-GN).Methods:The clinicopathological data of 33 patients with HBV-GN and 27 patients with hepatitis B and nephritis(HBV-CG)aged ≥60 years in the 90 th Hospital of the United Nations Support Force were retrospectively analyzed and statistically analyzed. Results:(1)Both the HBV-GN and HBV-CG groups were often men[26(78.8%) vs. 21(77.8%)]and had high rate of nephritic syndrome[18(54.5%) vs.15(55.6%)]. And patients in the HBV-GN group had higher incidence of hypertension than that in the HBV-CG group; (2)Membranous nephropathy(MN)was the main pathological type in both groups, and the rate of membrane proliferative glomerulonephritis(MPGN)was more found in the HBV-GN group than the HBV-CG group; (3)The proportion positive HBsAg, HBeAg and HBcAb test resultsand high viral load was significantly higher in the HBV-GN group than that in the HBV-CG group; (4)Multiple immune complex deposits were observed in the renal tissues of HBV-GN group, which was called the phenomenon of "all bright" ; (5)The pathological features in the HBV-GN group showed untypical manifestation of MN, the occasionally observed crescent formation, and the thickening of basement membrane in focal segmental glomerulosclerosis; (6)The incidence and the severity of renal tubule and interstitial lesions in HBV-GN group were significantly higher than those in HBV-CG group. Conclusions:Although there are many similarities in clinical manifestations and testing indicators between the elderly HBV-GN and HBV-CG patients, HBV-GN patients are still significantly different from HBV-CG patients in terms of serum virology and pathological changes.Therefore, we should pay attention to the serum HBV replication and renal pathological changes to provide a clinical basis for treating this kind of elderly patients.

ABSTRACT

Objective:To investigate the effect of epidermal growth factor receptor tyrosine kinase inhibitor on the radiosensitivity of human non-small cell lung cancer cells and its possible mechanism.Methods:Human non-small cell lung cancer cells H1299 were cultured in vitro. CCK-8 was used to detect the toxic effects of erlotinib on H1299 cells, IC 50 and IC 20 were calculated, and IC 20 was utilized as the drug concentration for subsequent experiments. The colony formation assay was performed to identifiy the effect of X-ray combined with erlotinib on H1299 cells, the radiosensitivity parameters were calculated, and the cell survival curves were delineated. Flow cytometry was conducted to detect the cell cycle distribution and apoptosis. Western blot analysis was used to detect the expression of EGFR/PI3K/AKT pathway and apoptosis-related proteins. Results:Erlotinib exerted inhibitory effect upon the proliferation of H1299 cells, IC 50 was calculated as 27.3 μmol/L, and 3.3 μmol/L for IC 20. X-ray combined with IC 20 concentration of erlotinib could reduce the cloning ability of H1299, increased the proportion of G 0/G 1 phase and G 2/M phase, decreased the proportion of S phase, aggravated cell apoptosis, down-regulated the expression of pEGFR and pAKT proteins, and up-regulated the expression of apoptosis-related proteins including Active Caspase 3 and Cleaved PARP. Conclusions:Erlotinib exerts a radiosensitizing effect on H1299. The possible mechanism is that erlotinib combined with radiation can suppress the EGFR/PI3K/AKT pathway, reduce the ability of repairing cell damage, change cell growth cycle and induce cell apoptosis.

ABSTRACT

Objective:To analyze the clinical characteristics of patients with different types of coronavirus disease 2019 (COVID-19).Methods:A total of 272 eligible COVID-19 patients who were admitted to Guangzhou Eighth People′s Hospital, Guangzhou Medical University from January 22 to February 15, 2020 were retrospectively enrolled. General characteristics, the first laboratory examination and imaging data of these patients were collected. According to the clinical classification, there were 236 cases in non-severe group (mild+ common type) and 36 cases in severe group (severe+ critical type). Comparisons between groups were performed by t test, chi-square test or rank-sum test when appropriate. Results:There were 23 males and 13 females in the severe group, 103 males and 133 females in the non-severe group, and the difference was statistically significant ( χ2=5.149, P=0.023). The age of severe group was (60.5±11.2) years, which was higher than that of non-severe group (46.8±15.7) years. The difference was statistically significant ( t=6.43, P<0.01). The lymphocyte (LYM) count, platelet (PLT) count and arterial partial pressure of oxygen (PaO 2) in the severe group were 0.90(0.55, 1.10)×10 9/L, 170.00(143.50, 198.00)×10 9/L and 73.50(69.70, 83.00) mmHg(1 mmHg=0.133 kPa), respectively, which were all lower than those in the non-severe group (1.42(1.09, 1.95)×10 9/L, 187.00(148.00, 230.00)×10 9/L and 96.00(83.20, 108.00) mmHg, respectively). The differences were all statistically significant ( Z=5.59, 2.00 and 5.00, respectively, all P<0.05). The levels of creatine kinase (CK), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), C reaction protein (CRP) and procalcitonin (PCT) in the severe group were 123.00(79.00, 212.00) U/L, 32.10(27.00, 47.40) U/L, 305.50(216.00, 396.00) U/L, 37.02(23.92, 63.66) mg/L and 0.09(0.05, 0.19) μg/L, respectively, which were all higher than those in the non-severe group (68.00(48.00, 103.00) U/L, 20.10(16.70, 26.20) U/L, 179.00(150.00, 222.00) U/L, 26.55(18.11, 36.96) mg/L and 0.04(0.03, 0.06) μg/L respectively), and the differences were all statistically significant ( Z=3.89, 5.60, 5.12, 2.85 and 5.43, respectively, all P<0.01). No significant differences were observed in white blood cell count, creatine kinase isoenzyme and blood lactate between the two groups ( Z=1.53, 0.41 and 1.00, respectively, all P>0.05). Conclusion:Gender, age, LYM count, PLT count, PaO 2, CK, AST, LDH, CRP and PCT could be used to provide reference for clinical classification of COVID-19 patients.
