ABSTRACT

@#AIM:To assess the changes of posterior corneal elevation after small incision lenticule extraction(SMILE). <p>METHODS:A retrospective study was conducted on 120 patients(240 eyes)who underwent SMILE surgery with myopia. All patients were examined with the Pentacam of preoperation and 1d, 1wk, 1, 3, 6 and 12mo postoperatively, respectively. We analyze the change of the posterior corneal elevation of the apex, and the change of mean posterior corneal elevation in the circle of 2mm, and 6mm diameter.<p>RESULTS:Comparison among the three groups showed that the differences of apex and 2mm circle at a different time and between the groups were statistically significant(apex: <i>F</i><sub>time</sub>=30.09, <i>P</i><sub>time</sub><0.01; <i>F</i><sub>group</sub>=7.29, <i>P</i><sub>group</sub><0.01; 2mm circle: <i>F</i><sub>time</sub>=24.72, <i>P</i><sub>time</sub><0.01; <i>F</i><sub>group</sub>=7.44, <i>P</i><sub>group</sub>=0.01), and there was no statistically significant difference in interaction time and groups(apex: <i>F</i><sub>time×group</sub>=1.65, <i>P</i><sub>time×group</sub>=0.15; 2mm circle: <i>F</i><sub>time×group</sub>=1.81, <i>P</i><sub>time×group</sub>=0.25). The difference of 6mm circle at different time points after the operation was statistically significant(<i>F</i><sub>time</sub>=18.34, <i>P</i><sub>time</sub><0.01), while the difference in interaction time and groups was not statistically significant(<i>F</i><sub>group</sub>=2.21, <i>P</i><sub>group</sub>=0.12; <i>F</i><sub>time×group</sub>=1.34, <i>P</i><sub>time×group</sub>=0.25). In the low and moderate myopia groups, the changes of the apex, 2mm circle and 6mm circle in the posterior corneal elevation were statistically significant within 1mo after surgery(<i>P</i><0.05); In the high myopia group, there were statistically significant at the apex and 2mm circle within 3mo after surgery(<i>P</i><0.05); There was statistically significant after surgery at 6mm circle within 1mo(<i>P</i><0.05). In all cases, the difference of the posterior corneal elevation between 1wk and 1d was negative at the apex and 2mm circle, after that, the difference became positive and smaller. The reverse was true at the 6mm circle. <p>CONCLUSION:Among three groups after SMILE, the central posterior cornea was slightly backward, and the peripheral cornea was slightly forward, the changes were most obvious after 1wk and then returned gradually. It means the surgery was safe, stable, precise, and predictable.

ABSTRACT

Objective:To explore the influence of the value of the echocardiography in the detection of cancer therapeutics-related cardiotoxicity by World Alliance Societies of Echocardiography(WASE) study.Methods:Tirty-seven breast cancer patients underwent echocardiography at baseline before chemotherapy (T0) and after the second (T2), fourth (T4), sixth (T6) chemotheraphy cycles in Qilu Hospital of Shandong University from March 2017 to March 2018. According to different guidelines[ASE lower limit of normal left ventricular ejection fraction(LVEF-LLN) 53%, ESC LVEF-LLN 50% and the WASE study (Women LVEF-LLN 58%, Asian Women LVEF-LLN 59%)], the number of patients with myocardial injury during chemotherapy was evaluated, and compared with the global longitudinal strain(GLS) standard, the percentages of patients with myocardial injury in different standards were analyzed.Results:With the up-regulation of LVEF-LLN, more patients with early myocardial damage were found. During chemotherapy, 1 patient showed left ventricular ejection fraction (LVEF) fell by >10% from baseline to LVEF<50% (2016 ESC Guidelines), 3 patients showed LVEF fell by >10% from baseline to LVEF<53% (2014 ASE Guidelines), 7 patients for LVEF fell by >10% from baseline to LCVEF<58%, and 9 patients for LVEF fell by >10% from baseline to LVEF<59%, which was still less than the number of patients detected by GLS criteria (18 patients), but the sensitivity of LVEF fell of >10% from baseline to LVEF<59% was not statistically different from GLS standard ( P>0.05). Conclusions:With the up-regulation of LVEF-LLN, the sensitivity of LVEF in evaluating early myocardial damage was increased, but GLS was still the most sensitive index to monitor the cancer therapeutics-related myocardial damage.

ABSTRACT

Objective:To study the clinical effects of Yishen-Shengxue Decoction on the prevention and treatment of bone marrow suppression in acute myeloid leukemia after chemotherapy. Methods:A total of 60 patients in Beijing Longfu Hospital from June 2018 to March 2020 were randomly divided into control group and observation group, 30 cases in each group. The control group was treated with western medicine and blood transfusion, while the observation group was treated with Yishen-Shengxue Decoction on the basis of the control group. Both groups were treated for 2 weeks. We recorded the occurrence time and duration of Ⅳ degree myelosuppression of the two groups, compared the score of symptoms and signs, injection volume of recombinant human granulocyte colony stimulating factor (G-CSF) and blood transfusion volume, and recorded the incidence of adverse reactions after chemotherapy. Results:The occurrence of myelosuppression in the observation group was significantly later than that of the control group (5.07 ± 0.87 d vs. 3.83 ± 1.15 d; t=4.695, P<0.01), and the duration of grade Ⅳ myelosuppression was significantly shorter than that of the control group (7.20 ± 0.76 d vs. 10.03 ± 1.30 d; t=10.305, P<0.01); The quantity of granulocyte colony stimulating factor injection in the observation group was significantly less than that of the control group (7.2 ± 0.8 vs. 10.0 ± 1.3, t=10.305), and the quantity of red blood cell suspension (2.5 ± 1.5 U vs. 4.7 ± 1.5 U, t=7.749) and platelet transfusion (1.7 ± 0.5 U vs. 3.1 ± 0.9 U, t=5.879) were significantly less than that of the control group ( P<0.01); the quantitative score of symptoms and signs in the observation group were significantly lower than thoseof the control group ( t values were 18.208, 15.129, respectively, all Ps<0.01). The adverse reactions of the patients in the observation group after chemotherapy were significantly less than those of the control group, and the incidence of infection, bleeding and ECG abnormalities were statistically significant ( χ2 values were 7.500, 10.000, 4.286, respectively, all Ps<0.01). Conclusion:Yishen-Shengxue Decoction is helpful to delay the occurrence of myelosuppression, and promote its recovery, reduce various adverse reactions during myelosuppression, and improve the quality of life.

ABSTRACT

In order to discuss the "entropy weight method" for weighting various indicators in the comprehensive evaluation of Angelicae Sinensis Radix slices(ASR), the quality of ASR was comprehensively evaluated by entropy weight-based gray systematic theory and cluster analysis. In this study, the contents of ferulic acid, volatile oil, polysaccharide, alcohol extract, water extract, moisture, total ash and acid-insoluble ash in 44 batches of ASR from different sources were determined. The entropy weight method was used for objective weighting. With relative correlation(r_i) as a measure, a multi-index comprehensive evaluation model was constructed for the quality of ASR. The results showed that the relative correlation value of 44 batches of ASR ranged from 0.301 9 to 0.662 9. There were certain differences in the quality of ASR from different sources. The ASR S1-S8, traceable and standardized in processing techno-logy, showed a high relative correlation degree and high quality ranking, indicating that the implementation of systemic management of the production chain of Chinese herbal pieces was beneficial to the quality control of ASR. The quality evaluation results of 44 batches of ASR were consistent with those of traditional geo-authentic habitats for ASR and the mainstream varieties of ASR on market, and basically consistent with the results of cluster analysis. This study suggests that the gray systematic theory based on the entropy weighting method can be used for the quality evaluation of ASR. The objective weighting of the entropy weight method improves the reliability of the gray correlation method and the scientificity of ASR quality evaluation.

ABSTRACT

@#Objective    To investigate the diagnostic value and the best criteria of multiplanar reconstruction (MPR) of spiral CT in recurrent laryngeal nerve lymph node metastasis. Methods    We performed multiplanar reconstruction of the spiral CT data of 138 esophageal carcinoma patients admitted to our hospital between December 2016 and June 2019, including 113 males and 25 females with an average age of 47-85 (63.03±15.58) years. The short and long diameters of recurrent laryngeal nerve lymph nodes were measured respectively, and then ratio of short to long diameter was calculated. The three parameters were contrasted with the pathological results and the receiver operating characteristic (ROC) curves for the parameters were drawn. Results    Of the 138 patients, 291 left recurrent laryngeal nerve lymph nodes were dissected with an average number of 0-14 (2.11±0.41) per patient and the metastasis rate was 16.70%; while 436 right ones were dissected with the average number of 0-17 (3.16±0.45) per patient and the metastasis rate was 21.00%. The total metastasis rate was 29.70%. In the diagnosis of lymph node metastasis, the areas under ROC curve for short and long diameters as well as the ratio of short to long diameter of left recurrent laryngeal nerve lymph nodes were 0.808, 0.779, 0.621, respectively, while those for the right ones were 0.865, 0.807, 0.637, respectively. Conclusion    The metastasis rate of recurrent laryngeal nerve lymph nodes is high and the short diameter has a higher diagnostic value for recurrent laryngeal nerve lymph node metastasis.

ABSTRACT

ObjectiveTo investigate the association of peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PPARGC1A) rs8192678 single nucleotide polymorphism (SNP) with the risk of nonalcoholic fatty liver disease (NAFLD) and the influence of PPARGC1A rs8192678 SNP on NAFLD-related biochemical parameters. MethodsA total of 119 NAFLD patients who attended Qingdao Municipal Hospital Affiliated to Qingdao University from December 2017 to December 2018 were enrolled as NAFLD group, and 213 individuals who underwent physical examination during the same period of time were enrolled as control group. Clinical data and blood samples were collected from all subjects to measure related biochemical parameters and detect PPARGC1A rs8192678 SNP. The chi-square test was used to determine whether the genotype distribution of samples was in accordance with the Hardy-Weinberg equilibrium. The t-test or the Wilcoxon rank-sum 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. A binary logistic regression analysis was used to investigate the risk factors for NAFLD. ResultsThere were no significant differences in the genotype and allele frequencies of PPARGC1A rs8192678 between the NAFLD group and the control group (χ2=0.011 and 0.015, P=0.918 and 0.904). The binary logistic regression analysis showed that CT genotype of PPARGC1A rs8192678 was not a risk factor for NAFLD (odds ratio=0.951, 95% confidence interval: 0.368-2.457, P=0.918). In the NAFLD group, the patients carrying CT genotype had a significantly higher level of gamma-glutamyl transpeptidase (GGT) than those carrying CC genotype (Z=-2.331, P=0.020). ConclusionPPARGC1A rs8192678 SNP does not increase the risk of NAFLD, while NAFLD patients carrying CT genotype tend to have a higher serum level of GGT.

ABSTRACT

OBJECTIVE@#To investigate the gene mutation occurved in AML patients with 29 kinds of fusion genes and 51 kinds of tumor gene.@*METHODS@#Next-generation sequencing (NGS) was used to detected the 49 kinds of targeted gene. FLT3 internal tandem duplication (FLT3-ITD), CALR, NPM1 and CEBPA mutation were detected by DNA-based PCR and Sanger sequencing. Twenty-nine kinds of fusion genes were dected by multiplex nested RT-PCR.@*RESULTS@#The total gene mutation rate was 91% (109/121) in all the 121 patients. On average, 2.1 mutated genes per patient were identified, among these 121 patients, coexistence of ≥ 3 mutations was frequent (34.7%). The most commonly mutated genes were NRAS (23.96%, n=29), followed by NPM1 (14.04%, n=17), CEBPA double mutations (14.04%, n=17), KRAS (11.57%, n=14),FLT3-ITD (10.74%, n=13), CSF3R (10.74%, n=13), TET2 (9.92%, n=12) and IDH1 (9.1%, n=11). Overall, fusion genes were detected in 47 (37.3%) patients, including AML/ETO (n=12), CBFβ/MYH11 (n=11), PML/RARa (n=12), MLL rearranagement realated mutation MLL-X (n=10). TLS/ERG (n=1) and DEK/CAN (n=1) in an order of decreasing frequency. Patients with normal karyotype (NK)- AML exhibited more mutations in CEBPA, NPM1, TET2, RUNX1 and IDH1, comparing with abnormal karyotype patients. KRAS mutation in abnormal kayotype patients was significantly higher than that in normal kayotype patients (P=0.014). TP53 mutations were predominantly associated with complex cytogenetics (P=0.199). KRAS mutations were more frequent in core binding factor (CBF) acute myeloid leukemia (AML) and 11q23/MLL rearrangement leukemia, compared with NK-AML (P=0.006 and 0.003, respectively). KIT mutations predominated in CBF-AML (P=0.006). JAK2V617F mutations were detected in two patients and co-occurred with AML-ETO fusions.@*CONCLUSION@#At least one mutation is observed in more than 90% patients. On average, more than 2 mutated genes per patient are identified. Some gene mutations are associated with gene rearrangement.

ABSTRACT

Objective@#This study aimed to assess the association of waist circumference (WC) with all-cause mortality among Chinese adults.@*Methods@#The baseline data were from Shanxi Province of 2002 China Nutrition and Health Survey. The death investigation and follow-up visit were conducted from December 2015 to March 2016. The visits covered up to 5,360 of 7,007 participants, representing a response rate of 76.5%. The Cox regression model and floating absolute risk were used to estimate hazard ratio and 95% floating of death by gender and age groups (≥ 60 and < 60 years old). Sensitivity analysis was performed by excluding current smokers; participants with stroke, hypertension, and diabetes; participants who accidentally died; and participants who died during the first 2 years of follow-up.@*Results@#This study followed 67,129 person-years for 12.5 years on average, including 615 deaths. The mortality density was 916 per 100,000 person-years. Low WC was associated with all-cause mortality among men. Multifactor-adjusted hazard ratios ( ) were 1.60 (1.35-1.90) for WC < 75.0 cm and 1.40 (1.11-1.76) for WC ranging from 75.0 cm to 79.9 cm. Low WC (< 70.0 cm and 70.0-74.9 cm) and high WC (≥ 95.0 cm) groups had a high risk of mortality among women. The adjusted s of death were 1.43 (1.11-1.83), 1.39 (1.05-1.84), and 1.91 (1.13-3.22).@*Conclusion@#WC was an important predictor of death independent of body mass index (BMI). WC should be used as a simple rapid screening and predictive indicator of the risk of death.

ABSTRACT

OBJECTIVE@#To evaluate the effect of femoral and sciatic nerve block in total knee replacement of elderly patients under general anesthesia.@*METHODS@#From July 2017 to July 2019, 60 patients with unilateral total knee replacement were selected, including 35 males and 25 females; aged 66 to 74(70.2±10.3) years;BMI 18 to 25 (21.3 ± 3.5) kg /m;course 2 to 3 (1.2±0.3) days. The patients were divided into general anesthesia group (G group) 30 cases and general anesthesia plus nerve block group(GNB group) 30 cases. In GNB group, the femoral nerve sciatic nerve block was guided by ultrasound before anesthesia induction, 20 to 25 ml was injected into the femoral nerve puncture point with 0.5% ropivacaine, 15 to 20 ml was injected into the sciaticnerve puncture point, and the total volume was no more than 40 ml. Postoperative intravenous analgesia (PCIA) was performed in two groups. The dosage of propofol and remifentanil was recorded. Forty-eight hours after operation, the incidence of postoperative nausea and vomiting (PONV) and postoperative farsightedness were recorded. When VAS>3, tramadol 2 mg / kg was injected intravenously, and the additional times of tramadol were recorded. Forty-eight hours after operation, patients' satisfaction score was used to record the length of stay.@*RESULTS@#Compared with group G, the dosage of propofol and remifentanil decreased, the incidence of PONV and the number of additional tramadol decreased, and the patients' satisfaction increased (0.05). The ROM and HSS scores of two groups after treatment were higher than those before treatment (0.05). The ROM and HSS scores of the GNB group after treatment were higher than those of the G group (<0.05), and the VAS scores were lower than those of the G group (<0.05).@*CONCLUSION@#The application of femoral sciatic nerve block in total knee replacement under general anesthesia in elderly patients has good postoperative analgesic effect, and can reduce the dosage of general anesthesia, reduce PONV, and increase patient satisfaction.

ABSTRACT

Hypoxia is a prominent feature of tumors. Hypoxia-inducible factor-1α (HIF-1α), a major subunit of HIF-1, is overexpressed in hypoxic tumor tissues and activates the transcription of many oncogenes. Accumulating evidence has demonstrated that HIF-1α promotes tumor angiogenesis, metastasis, metabolism, and immune evasion. Natural products are an important source of antitumor drugs and numerous studies have highlighted the crucial role of these agents in modulating HIF-1α. The present review describes the role of HIF-1α in tumor progression, summarizes natural products used as HIF-1α inhibitors, and discusses the potential of developing natural products as HIF-1α inhibitors for the treatment of cancer.

ABSTRACT

Autoimmune diseases are primary immune diseases in which autoreactive antibodies or sensitized lymphocytes destroy and damage tissue and cellular components, resulting in tissue damage and organ dysfunction. Helper T cells may be involved in the pathogenesis of autoimmune diseases under certain conditions. This review summarizes recent research on the role of helper T cells in autoimmune diseases from two aspects, helper T cell-mediated production of autoantibodies by B cells and helper T cell-induced activation of abnormal lymphocytes, and provides ideas for the treatment of autoimmune diseases. The abnormal expression of helper T cells promotes the differentiation of B cells that produce autoantibodies, which leads to the development of different diseases. Among them, abnormal expression of Th2 cells and T follicular helper cells is more likely to cause antibody-mediated autoimmune diseases. In addition, abnormal activation of helper T cells also mediates autoimmune diseases through the production of abnormal cytokines and chemokines. Helper T cells play an essential role in the pathogenesis of autoimmune diseases, and a full understanding of their role in autoimmune diseases is helpful for providing ideas for the treatment of autoimmune diseases.

ABSTRACT

OBJECTIVE@#To observe the application of modified traction therapy in traumatic atlantoaxial subluxation in adults.@*METHODS@#The clinical data of 31 patients with atlantoaxial subluxation treated from March 2018 to June 2019 were restropectively analyzed. There were 15 males and 16 females, aged from 18 to 68 years old with an average of 39 years old, including 10 cases of 18-40 years, 15 cases of 41-60 years, 6 cases of 51-68 years. The main manifestations of the patients were limited neck movement, pain, and atlantoaxial CT scan showed different degrees of atlantoaxial subluxation. Three dimensional multifunctional traction bed was used for traction for 2 min, relaxation for 10 s. The traction angle starts from the rearward extension of 5°-10° and weight from 3-6 kg. The weight increased by 1 kg every two days until the symptoms were improved. Traction time was 30 min twice a day and 10 days for a course of treatment. One course of treatment was performed in patients with 1-2 mm left and right equal width of atlantoaxial space, and two courses of treatment were performed in patients with 3-4 mm left and right equal width of atlantoaxial space, and the course of treatment could be increased to 3 months in especially patients with serious problems, such as 4 mm left and right equal width of atlantoaxial space and no improvement after conventional treatment. The criteria to evaluate the clinical effect was cure:no pain in the neck, normal range of neck movement, CT showed normal atlantoaxial space and odontoid process was in the middle, patients with normal neck movement were followed up 1 month after the end of treatment;improvement:neck pain was significantly improved and CT showed that the left and right atlantoaxial space was less than 1 mm in equal width.@*RESULTS@#Among the 31 patients, 17 cases were cured by one course of treatment, 11 cases were cured by 2 courses of treatment, and 2 caseswere improved.@*CONCLUSION@#The modified traction therapy has obvious effect on adult traumatic atlantoaxial subluxation, especially the subluxation of 3-4 mm equal width in left and right atlantoaxial space, and this method is safe and reliable with good efficacy and the patients without discomfort.

ABSTRACT

The paper was aimed to explore the role of serum exosomes induced by hepatic ischemia/reperfusion (I/R) injury in the damage of hippocampus and cerebral cortex of rats. The male Sprague-Dawley (SD) rats were randomly divided into 4 groups: sham operation group (S), hepatic I/R injury group (I/R), serum exosomes from S group treatment group (ES) and serum exosomes from I/R group treatment group (EI). In ES group and EI group, 100 μL serum exosomes from S group and I/R group were injected into the normal rats through tail vein respectively. Another three normal rats were injected intravenously with serum exosomes labeled with PKH26 red fluorescence, and then the expression of fluorescence in the brain tissues was observed by immunofluorescence microscope. The morphology and size of exosomes were observed by transmission electron microscope, the expression of exosomes markers CD63 and CD9 was detected by Western blot, and the damage of liver and brain, levels of apoptosis and oxidative stress response in hippocampus and cerebral cortex were observed by serological and histological indexes. The results showed that the exosomes were a group of round or ovoid membranous vesicles, sized in 30-100 nm. Compared with that in S group, the content of serum exosomes in I/R group was increased (P < 0.05). Moreover, serum exosomes could go through the blood-brain barrier and enter the brain tissue freely through blood circulation. The index of liver function in I/R group was significantly higher than that in S group (P < 0.05). There was no significance in the degree of brain damage, apoptosis and oxidative stress in hippocampus and cerebral cortex between S group and ES group. Compared with those in S group and ES group, the serum levels of brain injury markers, apoptosis index (AI) and oxidative stress in hippocampus and cerebral cortex increased in I/R group and EI group (P < 0.05). Whereas, compared with those in I/R group, the above indicators in EI group decreased (P < 0.05). Therefore, hepatic I/R injury can lead to the damage of hippocampus and cerebral cortex, and the increased serum exosomes induced by hepatic I/R plays an important role.

ABSTRACT

The transforming growth factor-β-activated kinase 1 (TAK1) is a member of the mitogen-activated protein kinase kinase kinase (MAPKKK) family. TAK1 plays important roles in many biological functions. Cardiac hypertrophy can be identified as physiological or pathological myocardial hypertrophy. TAK1 not only participates in the development of normal myocardium, but also plays an important role in regulating the occurrence and development of pathological myocardial hypertrophy. Angiotensin II (Ang II) or pressure overload induces pathological cardiac hypertrophy through different ways, such as hypoxia-inducible factor-1α (HIF-1α)-mediated transcriptional expression of TAK1, or transforming growth factor-β1 (TGF-β1)-, thyroid hormone-, ubiquitin protease-mediated TAK1 phosphorylation or ubiquitination. This article reviews the role of TAK1 in the occurrence and development of pathological myocardial hypertrophy and discusses the potential of TAK1 as an important target for the prevention and treatment of clinical myocardial hypertrophy.

ABSTRACT

This article reported a case of malignant insulinoma which recurred as liver metastasis 12 years after the initial pancreatic insulinoma resection. The patient was a 48-year-old woman who was firstly diagnosed as pancreatic insulinoma in 2006 and underwent the surgery involved complete resection of a 1.9 cm×1.3 cm tumor located in pancreas. No signs of either invasion or metastasis was detected according to preoperative imaging examination and intraoperative exploration. The tumor was diagnosed as a benign insulinoma according to histopathological results. The patient had no hypoglycemia and the fasting blood glucose was normal during the subsequent 12 years. The patient underwent a fasting blood glucose of 2.8 mmol/L in 2018, and gradually experienced palpitation and cold sweats, which was relieved by eating. She was hospitalized in May 2018 with blood glucose of 1.73 mmol/L and insulin of 1 128 pmol/L. CT and MRI revealed morphologic changes of postoperative pancreas and abnormal liver signal, the liver tumor was finally identified as insulinoma by modified selective intra-arterial calcium stimulated venous sampling (ASVS). Partial liver resection was performed and the histopathological result was neuroendocrine tumor. Therefore, the disease was diagnosed as liver metastatic malignant insulinoma.
