RESUMEN
AIM: To understand the current status and differences in visual acuity of children of the same age from different regions of Xi'an, and to take an effective basis for the prevention of children's myopia.METHODS: Random stratified sampling was used to select the uncorrected distance visual acuity and computed dioptric data of 41 285 children aged 6-12 from 6 towns, 10 urban and rural areas and 112 country schools screened by Xi'an Central Hospital in December 2022.RESULTS: The myopia detection rate in different regions of Xi'an is 47.16% in towns, 38.59% in urban and rural areas, and 32.29% in the country, and the total myopia rate is 37.50%. The myopia rate of 6-12 years old in towns is higher than that in urban and rural areas, and that of urban and rural areas is higher than that of country; the myopia rate of girls is higher than that of boys; myopia rate increases with age; mild myopia: the myopia rate in towns is significantly higher than that of the urban and rural areas and the country; high myopia: the myopia rate in the country is significantly higher than that of the towns and the urban and rural areas. The total rate of deficient hyperopia reserves in different regions of Xi'an is 92.08% in towns, 93.67% in urban and rural areas, and 90.92% in the country, and the total rate of deficient hyperopia reserves is 92.09%. The rate of deficient hyperopia reserves at the age of 6-12 is higher in the urban and rural areas than in the towns, and higher in the towns than in the country; the total rate of deficient hyperopia reserve is higher in girls than in boys; it is the peak period of the development of hyperopia reserve rate before the age of 8.CONCLUSION: The total myopia rate and the total vision reserve deficiency rate of 6-12 years old in different regions of Xi'an are different, and 8-9 years old is the accelerated period of myopia development, and the peak of deficient hyperopia reserve is before the age of 8 years old. With the growth of age, the myopia rate shows a certain growth trend, and the rate of deficient hyperopia reserve shows a decreasing trend after reaching the peak. The total myopia rate and insufficient acuity reserve rate of girls are higher than those of boys.
RESUMEN
Objective To analyze the prevalence and co-prevalence of cardio-metabolic related risk factors in farmers aged ≥18 years in China,to explore the influence of population economic factors on them.Methods A total of 3 367 farmers,including fishermen or hunters,aged ≥ 18 years were selected as study subjects from the database of Nutritional Status and Health Transition of Chinese Residents Project in 2015.Basic information (age,gender),data on anthropometric (body height,weight and waist size),blood biochemical and socioeconomic (occupation,income,education level and living area) were included.According to the definition of the metabolic syndrome released by the International Diabetes Federation (IDF) in 2005,five cardio-metabolic risk factors appeared as central obesity,increased triglycerides,decreased HDL-C,increased blood pressure and increased plasma glucose.Co-prevalence of risk factors was defined as detecting 2 or more risk factors in a person at the same time.Multivariate logistic regression model was used to analyze the relationship between socioeconomic factors and metabolic risk factors.Results In 3 367 framers of 15 provinces (autonomous region and municipality),the prevalence rates of central obesity,increased blood pressure,increased plasma glucose,increased triglycerides and decreased HDL-C were 51.8％,59.0％,17.0％,25.5％ and 38.7％ respectively.Multivariate logistic regression analysis showed that the risks for central obesity (OR=3.69,95％CI:3.17-4.28) and decreased HDL-C (OR=3.28,95％CI:2.81-3.82) were higher in women than in men,and the risks for increased blood pressure (OR=0.73,95％ CI:0.63-0.84),increased blood glucose (OR=0.80,95％ CI:0.67-0.97) were lower in women than in men.Age was positively correlated with the prevalence or co-prevalence of metabolic risk factors (trend P＜0.05).Framers in western China had obviously lower risk for central obesity compared with farmers in central China.No significant correlation was found between farmers' income level,education level or the prevalence of metabolic risk factors.Conclusion In 15 provinces of China,the prevalence of at least 1 kind of cardio-metabolic risk factor was found in 85.5％ of the farmers,and the co-prevalence of cardio-metabolic risk factor was found in 60％ of farmers.The prevalence and co-prevalence of cardio-metabolic risk factors were significantly associated with age and gender.It is suggested to take targeted nutritional intervention and health education according to the distribution characteristics of prevalence and co-prevalence of cardio-metabolic factors and strengthen the early prevention and control programs of the diseases.

RESUMEN
Objective In view of the controversy over radiotherapy target volume for patients with limited-stage small cell lung cancer ( SCLC), a prospective randomized controlled trial was conducted to compare the impact of different radiotherapy target volumes on prognosis. Methods After 2 cycles of EP chemotherapy,patients without progressive disease were randomly assigned to receive thoracic radiotherapy (TRT) to either the post-or pre-chemotherapy primary tumour extent as study arm or control. Involved field radiotherapy (IFRT) to the entire metastatic lymph node regions was applied for both arms. TRT consisted of 45 Gy/30Fx/19 d administered concurrently with cycle 3 chemotherapy. Prophylactic cranial irradiation was administered to patients achieved complete or partial remission. Kaplan-Meier method was used for survival analysis. Results Between June 2002 and December 2017,159 and 150 patients were randomly assigned to study arm and control respectively. The 1-,2-,and 5-year local/regional control rates were 79. 4%,61. 5% and 60. 1% respectively in the study arm versus 79. 8%,66. 5%,and 57. 3% in the control arm (P=0. 73). The median OS time was 22. 1 months in the study arm (95%CI,18. 2-26. 0 months) and 26. 9 months (95%CI,23. 5-30. 3 months) in the control arm,the 1-,3-,5-,and 7-year OS rates were 81. 1%,31. 6%, 23. 9% and 22. 2% respectively in the study arm versus 85. 3%,36. 6%,26. 1% and 20. 0% in the control arm (P=0. 51).Grade 2-3 acute esophagitis was developed in 32. 9% and 43. 2% of patients respectively in study arm and control arm (P=0. 01),while grade 2-3 pulmonary fibrosis was observed in 2. 0% and 10. 9% of patients ( P= 0. 01 ) respectively. Conclusions For patients with limited-stage SCLC who received induction chemotherapy,thoracic radiotherapy can be limited to post-chemotherapy tumour extent and IFRT can be routinely applied.
RESUMEN
Aim To investigate the protective effect of Glucogon like pep tide-1 (GLP-1 )on H9C2 cardio-myocytes against AGEs-induced apoptosis and the po-tential molecular mechanisms.Methods H9 C2 car-diomyocytes cells cultured in vitro were divided into the following groups:normal control group ,1 0 0 mg · L-1 AGEs group,100 mg·L-1 AGEs+10 nmol·L-1 GLP-1 group,100 mg·L-1 AGEs+5 mmol·L-1 N-acetyl-cysteine (NAC)group.Cell viabillity rate was meas-ured by CCK-8 assay,ROS production was measured by DCFH-DA fluorescent probe;Cells in different groups were stained with Annexin V-FITC/PI and then apoptotic rate was detected by flow cytometry;Nucleus morphology was observed under fluorescence micro-scope after being incubated with Honchest 33258;Bax, Bcl-2 mRNA gene expression was measured using RT-PCR;Western blot was applied to assess the apoptotic components expression including Bax and Bcl-2.Re-sult Compared with control group,cell viability rate in AGEs group was decreased in a dose-dependent manner;cell apoptosis and ROS production in H9 C2 cells were remarkably increased in AGEs group.How-ever,compared with AGEs group,GLP-1 reduced ROS production and ameliorated cell apoptosis caused by AGEs;the expression of pro-apototic proteins Bax was decreased,the expression of anti-apoptotic proteins like Bcl-2 was increased. Conclusion GLP-1 protects H9 C2 cardiomyocytes against AGEs-induced apoptosis, which may be related to the reduction of the active oxy-gen (ROS).
RESUMEN
Objective: To investigate the efficacy and safety of using pegylated recombinant human granulocyte-colonystimulating factor (PEG-rhG-CSF) in preventing neutropenia in multiple chemotherapy cycles. Methods: A multicenter, prospective, open-label, singlearmstudy was designed. Patients with malignant tumors, such as lung, ovarian, and colorectal cancers, who received multiple cycles of chemotherapy with the prophylactic use of PEG-rhG-CSF for 2-4 consecutive cycles participated in the study. Results: After the prophylactic use of PEG-rhG-CSF, the incidence of grade IV neutropenia decreased from 4.76% (13/273) in the first cycle to 1.83% (5/273), 1.15% (2/174), and 2.08% (2/96) in subsequent cycles. Meanwhile, the incidence of grade III neutropenia decreased from 11.36% (31/ 273) in the first cycle to 6.23% (17/273), 2.87% (5/174), and 3.13% (3/96) in subsequent cycles. The incidence of febrile neutropenia (FN) during the first cycle was 0.73% (2/273). The duration of FN was 2 days in one case and 5 days in another case. FN was not observed during the second, third, or fourth cycle. After the secondary prophylactic use of PEG-rhG-CSF, the incidence of grade IV neutropenia decreased from 25% (7/28) to 3.57% (1/28), 0% (0/28), and 6.67% (1/15) in subsequent cycles. Meanwhile, the incidence of grade III neutropenia decreased from 71.43% (20/28) to 10.71% (3/28), 14.29% (4/28), and 0% (0/15) in subsequent cycles. The proportion of patients who received antibiotic therapy during the entire chemotherapy period was 10.48% (44/420). Conclusion: The application of PEG-rhG-CSF once per chemotherapy cycle can effectively reduce the occurrence of neutropenia in patients under multiple cycles of chemotherapy treatment with good safety.

Targeted agents for small cell lung cancer (SCLC)include inhibitors of angiogenesis,tyro-sine kinase inhibitors and signal transduction pathway inhibitors.Bevacizumab,a class of antiangiogenic agent, tends to have no effects on patients.The tyrosine kinase inhibitor,for example sunitinib,may be used as a monotherapy.Signaling inhibitors including Amuvatinib and LDE225 are undergoing phaseⅠand Ⅱ trials.Pri-mary data show that SCLC is not sensitive to targeted therapy,needing more selection,so further studies are requested.
RESUMEN
Background and purpose:Methylene tetrahydrofolate reductase (MTHFR) plays an important role in metabolism of folate and DNA methylation. This study aimed to investigate the relationship between methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism and chemotherapy side effects in advanced non-small cell lung cancer (NSCLC) patients. Methods:A total of 100 patients with advanced NSCLC conifrmed by pathology were included into this study in Zhejiang Cancer Hospital from Jun. 2007 to May. 2009. All patients received the combined chemotherapy of platinum drug and gemcitabine. MTHFR genotypes were determined by allele-specific-PCR technology. Results:In the 100 cases, genotype frequency of MTHFR C677T T/T, T/C and C/C were 20%, 44%and 36%, respectively. Compared with patients of T/T and T/C genotype, patients of C/C genotype were correlated with decreased rate of thrombocytopenia to chemotherapy (P=0.039). No signiifcant differences were observed concerning gastrointestinal toxicity. Conclusion:MTHFR C677T gene polymorphism can be used to predict the adverse reactions to platinum-based chemotherapy in patients with advanced NSCLC.
RESUMEN
<p><b>BACKGROUND</b>The preclinical experiments and several clinical studies showed icotinib, an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, in Chinese patients with advanced non-small cell lung cancer (NSCLC) who failed previous chemotherapy. We performed a retrospective study of the efficacy and safety of icotinib monotherapy in a different and more recent sample of Chinese patients.</p><p><b>METHODS</b>The clinical data of 149 patients with advanced NSCLC who were admitted to Zhejiang Cancer Hospital from August 1, 2011 to July 31, 2012 were retrospectively analyzed. All patients were given icotinib treatment after the failure of previous chemotherapy. Univariate and multivariate analyses were conducted based on the Kaplan Meier method and Cox proportional hazards model.</p><p><b>RESULTS</b>The objective response rate was 33/149 and disease control rate was 105/149. No complete response occurred. Median progression free survival (PFS) with icotinib treatment was 5.03 months (95% CI: 3.51 to 6.55). Median overall survival was 12.3 months (95% CI: 10.68 to 13.92). Multivariate analysis showed that the mutation of EGFR and one regimen of prior chemotherapy were significantly associated with longer PFS. At least one drug related adverse event was observed in 65.8% (98/149) of patients, but mostly grade 1 or 2 and reversible and none grade 4 toxicity.</p><p><b>CONCLUSIONS</b>Icotinib monotherapy is an effective and well tolerated regimen for Chinese patients with NSCLC after the failure of chemotherapy. It is a promising agent and further study with icotinib in properly conducted trials with larger patient samples and other ethnic groups is warranted.</p>

Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) show good efficacy for the lung cancer patients with EGFR mutations.Chemotherapy drugs are the first choices for the lung cancer patients with EGFR wild-type.In basic research,EGFR-TKIs combination with chemotherapy drugs show good synergy.But in clinical research,the timing of EGFR-TKIs combination with chemotherapy drugs is related to the efficacy.
RESUMEN
Anemia is commonly observed in lung cancer patients,and it is mainly caused by chemotherapy.Anemia can cause several debilitating symptoms such as fatigue and tachycardia which will not only influence the patients' quality of life and therapy effect,but also short the survival time.So anemia has been regarded as a poor independent prognostic indicator of the disease.Transfusion the erythrocytes and using the erythropoiesis stimulating agents is the main treatments of the disease.Using the erythropoiesis stimulating agents is the main treatment before the hemoglobin decreasing significantly in order to reduce the times of transfusion.Keeping the hemoglobin between 10.0-12.0 g/dl can improve the patients' quality of life and avoid the adverse events such as thrombus formation at the same time.
RESUMEN
Thrombosis disease is a common complication of cancer. Researches show that venous thromboembelism ( VTE ) can increase the mortality rate of patients with cancer.Tissue factor (TF) and cancer procoagulant (CP) and other pathological factors are related to VTE.VTE risk factors in cancer patients can be grouped into 3 general categories:patient-related factors,cancer-related factors and treatment-related factors.Assessment of risk factors and early prevention can reduce the incidence of VTE.Immediate treatment and chronic therapy should be performed immediately after the diagnosis of VTE.
RESUMEN
Small-cell lung cancer (SCLG) relapses in the majority of patients,even though most patients respond to first-line therapy.Subsequent therapy can provide significant palliation and prolongation of survival for many patients. At present,topotecan is considered the standard second-line chemotherapy.Recently,amrubicin has also shown more favorable antitumor activity,and is the most promising at present.Unfortunately,targeted agents have failed to demonstrate effectiveness for SCLC.
RESUMEN
Aberrant promoter methylation in special genes such as tumor suppressor genes is early eventin carcinogenesis of lung cancer. Aberrant methylation, resulting in corresponding mRNA silence or overexpression , closely relates to carcinogenesis, development, treatment response and prognosis of lung cancer and it may become a potential biomarker. Methylation of special genes may provide evidences for individual treatment of lung cancers.
RESUMEN
Objective To study the antitumor effects of exosomes derived from heat-shocked E.G7-OVA tumor cells in vivo. Methods Exosomes derived from E.G7-OVA tumor cells were isolated and purified by serial centrifugation and sucrose gradients ultracentrifugation. Exosomes from heat-shocked or non-heat-shocked E.G7-OVA tumor cells were named as Exo/HS and Exo correspondingly. Exosomes were viewed by electron microscopy. Protein components of exosomes were detected by Western blot. Exo, Exo/ HS or PBS were injected into mice before injection of E.G7-OVA tumor cells, and antitumor effects were ob-served in each group. Mouse model bearing E.G7-OVA tumor cells were established to examine immunother-apy effects of Exo or Exo/HS. Cytotoxity of spleen CTL were measured by LDH. Results Exosomes con-tained bi-layer membrane and their diameters are between 40 nm and 100 nm under electron microscopy. The Western blot results showed that HSC70, HSP70, HSP60, HSP90, MHC Ⅰ and OVA were present in both Exo and Exo/HS. However, Exo/HS contained more HSP70 and MHC Ⅰ than Exo. Protective antitu-mor immunity suggested that tumor-free survival (90 days) rate in Exo/HS vaccinated mice was significantly higher than those in Exo or PBS vaccinated mice (50%, 20%, 0%, P<0.01). Therapeutic antitumor effects showed that immunization by Exo/HS resulted in dramatically enhanced antitumor effects when com-pared to the Exo- or PBS-treated groups (P<0.01). CTL results showed that immunization with Exo/HS in-duced higher level of OVA-specific CTL responses as compared with those from Exo or PBS (P<0.01). Conclusion Exosomes derived heat-shocked E.G7-OVA tumor cells may be used as potent cancer vaccine.

Objective To evaluate the efficacy and safety of sorafenib in the treatment of Chi-nese patients with metastatic renal cell carcinoma. Methods This muhicenter phase Ⅱ clinical trial was performed from May 2006 to December 2006. Sixty-two patients with metastatic renal cell carci-noma not suitable for curative treatment were enrolled. All patients received oral sorafenib as single a-gent at the dose of 400 mg twice a day until disease progression or intolerable toxicities occurred. Re-salts Partial responses were recorded as best response in 11 patients, while complete remission was found in 1 patient and stable diseases were found in another 35 patients. According to the intents-to-treatment population, the overall response rate was 19.4% (12/62), and the disease control rate was 77.4%(48/62). The median progression free survival time was 9.6 months with 1-year progression-free survival rate of 41.9%. However, the median survival time had not reached due to the short fol-low-up. The most frequent adverse events included alopecia (66.1%), diarrhea (62.9%), hand-foot syndrome (58.1%), anorexia (40.3%), rash(37.1%), fatigue (37.1%), hypertension (35.5%), hoarseness(32.3%), joint pain (25.8%), hypophosphatemia (21.0%), fever (19.4%), nausea (19.4%), abnormal transeaminase( 11.3% ), elevated total bilirubicin( 16.1% ), leucopenia( 12.9% ), bleeding under nail(16.1%), and gum bleeding(11.3%). Grade 3 adverse events included hand-foot syndrome (16.1%), hypertension (12.9%), diarrhea(6.5%), hypophosphatemia (4.8%), joint pain (3.2%), and leucopenia(3.2%). Conclusions Sorafenib has prominent anti-tumor activity in Chi-nese metastatic renal cell cancer patients with most adverse events being grade 1 or 2. More attention should be paid to hypertension and cardio-cerebral vascular events during the application of sorafenib.
