Objective To analyze copy number variance (CNV) in whole genome by using gene chip technology, and to screen the radiosensitivity associated genes on esophageal squamous cell carcinoma (ESCC). Methods The patients with ESCC who received radiotherapy alone in Anyang Tumor Hospital from December 2013 to August 2016 were selected, and biopsy paraffin samples were preserved in the center of pathology. The patients were divided into radiosensitivity group (group S) and radio-resistance group (group R). DNA was extracted from these paraffin samples in both groups. Whole human genome CNV was detected by using genechip from OncoScan Array platform designed by Affymetrix company, and the differences of gene segments were screened in the two groups. Results Nineteen samples of ESCC patients were collected to extract DNA in this study. To balance pair analysis in the two groups, 10 samples were selected from the qualified patients, including 5 cases in group S and 5 cases in group R respectively. There were no statistical differences in gender, age, lesion site, lesion length, radiation dose of the two groups (all P> 0.05). Loss of heterozygosity (LOH) was the main type of CNV. The analysis results showed that LOH in q24.32-q24.33 of chromosome 10 and LOH in q21.2-q21.31 of chromosome 18 had high frequencies (100 %) in group R, however, none were detected in group S. LOH in q27-q28.1 of chromosome 4 had a high frequency (80%) in group S , however, none were detected in group R. Conclusion LOH in 10q/18q is related to radio-resistance in ESCC, and LOH in 4p is associated with radiosensitivity in ESCC.

BACKGROUND:Hemiarthroplasty is a proven method for reconstruction of the hip joint function, especialy for the elderly patients who cannot tolerate the total hip arthroplasty. However, for the patients with osteoporosis, there are stil more controversial in clinical practice about using cemented or cementless femoral prosthesis for hemiarthroplasty. OBJECTIVE: To observe the repair effect of cemented or cementless femoral prosthesis when were used for hemiarthroplasty in patients with osteoporosis. METHODS:The clinical data from 105 patients treated with hemiarthroplasty were retrospectively analyzed. Osteoporosis was diagnosed in these patients using the dual energy X-ray absorptiometry before surgery.Patients were divided into bone cement group (n=56) and cementless group (n=49) depending on different types of femoral stem prosthesis. The difference of efficacy between cemented or cementless femoral prosthesis when were used for hemiarthroplasty in patients with osteoporosis was analyzed by comparing the operative time, volume of drainage, post-operative Harris scores of hip joint function and radiographic assessment (prosthesis subsidence, osteolysis, severe stress shielding, heterotopic ossification) during the folow-up after the replacement. RESULTS AND CONCLUSION:In the process of hemiarthroplasty in patients with osteoporosis, the operative time in the cement group was significantly longer than that in the cementless group (P < 0.05). However, there was no significant difference in the postoperative volume of drainage between these two groups (P > 0.05). At the 1, 3, 6 and 12 of folow-up after replacement, there were no significant differences in the Harris score of hip joint function, total effective rate and radiographic assessment between these two groups (P> 0.05). These results suggest that in the process of hemiarthroplasty in patients with osteoporosis, the clinical efficacy of cementless femoral prosthesis is similar to the cement femoral prosthesis, therefore two prostheses can al be selected; however, the operative time of the cement femoral prosthesis is longer than the cementless femoral prosthesis, so we can give priority to the cementless femoral prosthesis for patients with osteoporosis who can’t tolerate a long operative time because of the poor basic condition.

Objective:To compare the prognosis of fluoroucil combined with cisplatin and paclitaxel combined with cisplatin regimens with concurrent radiotherapy in treatment of esophageal squamous cell carcinoma.Methods:A total of 120 patients with esophageal squamous cell carcinoma who were admitted to Anyang Tumor Hospital of Henan Province from December 2012 to November 2018 were randomly divided into group A and group B by using a random number generator. Group A was given cisplatin combined with 5-fluorouracil, and group B was given cisplatin combined with paclitaxel. Both groups had the same radiotherapy regimen, and both used intensity-modulated radiation therapy (IMRT). Completions of 50 Gy radiotherapy and at least one cycle of chemotherapy were considered to be in line with the plan. Survival data was analyzed in the term of intention-to-treat (ITT) and per-protocol (PP) set.Results:Of the 120 patients, 114 patients were treated and the adverse reactions could be evaluated, including 55 cases in group A and 59 cases in group B. The incidence of grade Ⅲ-Ⅳ leukopenia in group B was higher than that in group A [49.2% (29/59) vs. 25.5% (14/55)], and the difference was statistically significant ( χ2 = 6.805, P = 0.012), and there were no statistical differences in the other adverse reactions between the two groups (All P > 0.05). A total of 113 cases can be analyzed for survival. According to ITT analysis, the median progression-free survival (PFS) time in group A and group B was 28.0 months (95% CI 15.5-34.5 months) and 27.0 months (95% CI 17.0-41.0 months), the median overall survival (OS) time was 28.0 months (95% CI 15.8-34.2 months) and not reached, the differences were not statistically significant (both P > 0.05). According to PP analysis, the median PFS time in group A and group B was 28.0 months (95% CI 15.8-34.2 months) and 29.0 months (95% CI 14.9-45.1 months), the median OS time in group A and group B was 28.0 months (95% CI 3.7-52.3 months) and not reached, the differences were not statistically significant (both P > 0.05). Conclusions:The fluorouracil combined with cisplatin regimen and paclitaxel combined with cisplatin regimen with concurrent radiotherapy have similar PFS and OS time in treatment of esophageal squamous cell carcinoma, the adverse reactions are different, but they are all tolerable. In individualized clinical practice, the toxicities and costs of the two regimens can be comprehensively considered.

Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease with complex and diverse pathogenesis, and there is no effective treatment or specific drugs for its clinical treatment. In recent years, its incidence has been on the rise, and it has become the earnest expectation of medical researchers in China and abroad that related patients could be treated. AMP-activated protein kinase (AMPK) functions to regulate cellular energy homeostasis and mitochondrial homeostasis. When activated, it has a good intervention effect on NAFLD progression with lipid metabolism disorders and mitochondrial homeostasis disorders. For NAFLD, the activation of AMPK can inhibit the production of new lipogenesis in the liver, promote the oxidation of fatty acids in the liver, and enhance the mitochondrial function of adipose tissues. As a key target of metabolic diseases, AMPK can also improve apoptosis, liver fibrosis, autophagy, and inflammation. Traditional Chinese medicine (TCM) is good at treating diseases from multiple targets and multiple pathways and is also commonly used in the treatment of chronic liver disease in clinical practice. A large number of in vitro and in vivo experimental studies on NAFLD have shown that TCM monomers have good prospects for the treatment of NAFLD through the AMPK signaling pathway, including glycosides, phenols, alkaloids, flavonoids, quinones, terpenoids, and lignans, which are natural activators of AMPK. This study reviewed the research progress on TCM monomers in regulating the AMPK pathway to prevent and treat NAFLD, providing a broader perspective for TCM treatment of NAFLD.

OsRhoGDI2 was isolated as a putative partner of Rho protein family member OsRacD from rice panicles by yeast two-hybrid, but its function remains unknown. In order to identify the function of OsRhoGDI2, OsRhoGDI2 knockout mutants were created by CRISPR/Cas9 technology. The results showed that two different homozygous mutants were obtained in T0 generation, and eight kinds homozygous mutants were identified in T1 generation. Sequence analysis revealed that the base substitution or base deletion occurred near the editing targets of the gene in knockout rice, and it could be expected that the truncated OsRhoGDI2 proteins lacking the RhoGDI conserved domain would be generated. Phenotype analysis showed that the OsRhoGDI2 knockout rice plants were significantly lower than the control plants. Statistical analysis confirmed that the significant decrease of plant height was due to the shortening of the second and third internodes, suggesting that OsRhoGDI2 gene may be related with rice height control.
