Acupuncture clinical trials are designed to provide reliable evidence of clinical efficacy, and SCI papers is one of the high-quality clinical efficacy of acupuncture research. To analyze these papers published in high impact factor journals on acupuncture clinical trials, we can study clinical trials from design to implementation, the efficacy of prevention and cure, combined with international standard practices to evaluate the effectiveness and safety of acupuncture. That is the core of acupuncture clinical trials, as well as a prerequisite for outstanding academic output. A scientific and complete acupuncture clinical trial should be topically novel, designed innovative, logically clear, linguistically refining, and the most important point lies in a great discovery and solving the pragmatic problem. All of these are critical points of papers to be published in high impact factor journal, and directly affect international evaluation and promotion of acupuncture.

Objective:To investigate the clinical characteristics and related factors of patients with chronic obstructive pulmonary disease (COPD) complicated by obstructive sleep apnea (OSA).Methods:The clinical data of 153 patients with COPD who received treatment in Xiangyang First People's Hospital from July 2018 to December 2019 were retrospectively analyzed. A total of 101 patients with complete data regarding pulmonary function and polysomnography who met inclusion criteria were selected. They were divided into simple COPD (COPD group, n = 33) and COPD + OSA (OS group, n = 68) groups according to whether they developed OSA. General clinical data, pulmonary function indexes and polysomnography indexes were compared between the COPD and OS groups. Logistic regression analysis was performed to analyze the degree of airflow limitation and the related factors of COPD combined with OSA. Results:There were more males than females in each group. In the OS group, the proportion of males, body mass index, forced expiratory volume in one second (FEV 1), forced expiratory volume in 1 second percent predicted (FEV 1%pred), the ratio of FEV 1 to forced vital capacity (FVC), apnea-hypopnea index and oxygen desaturation index in the OS group were 92.6%, 24.0 (23.4, 24.8) kg/m 2, 1.2 (1.2, 1.5) L, 50.0 (49.6, 59.4)%, 49.1 (46.9, 53.0)%, 15.4 (16.4, 25.3) times/h, 14.8 (17.3, 25.6) times/h, respectively, which were significantly higher than those in the COPD group [75.8%, 23.0 (21.6, 23.7) kg/m 2, 0.9 (0.9, 1.1) L, 41.0 (38.3, 49.1) %, 41.9 (39.5, 49.24)%, 1.9 (1.6, 2.4) times/h, 4.0 (3.7, 9.7) times/h, t or U = 4.246, 1 399.000, 1 544.500, 1 483.000, 1 407.000, 2 244.000, 1 915.000, all P < 0.05]. The lowest oxygen saturation at night in the OS group was significantly lower than that in the COPD group [81.5 (79.4, 82.6) % vs. 87.0 (80.2, 86.6) %, U = 758.500, P < 0.05]. There were no significant differences in age, smoking index and forced vital capacity between COPD and OS groups ( t = - 0.963, 1 150.000, - 1.954, all P > 0.05). Correlation and Logistic regression analysis revealed that the risk of severe or very severe airflow limitation was lower in the OS group than in the COPD group ( OR = 0.392, P < 0.05). BMI, FEV 1, FEV 1%pred were the risk factors of COPD combined with OSA ( OR = 1.185, 5.554, 1.034, all P < 0.05). BMI and FEV 1 were the independent risk factors of COPD combined with OSA ( OR = 1.168, 5.248, both P < 0.05). Conclusion:COPD and OSA are more common in males and in patients with higher BMI. OSA patients tend to develop lower degree of airflow limitation and more severe hypoxemia and apnea-hypopnea at night than COPD patients. Apnea-hypopnea index is the protective factor against airflow limitation in COPD. BMI, FEV 1 and FEV 1%pred are the risk factors of COPD combined with OSA. BMI and FEV 1 are the independent risk factors of COPD combined with OSA.

Background The deficiency of limbus stem cells will cause various kinds of the disorder of eye surface,in serious condition,it will lead to corneal conjunctivalization,chronic inflammation,lasting deficiency of corneal epithelium and corneal opacity accompanying long-term visual loss.Objective The aim of this study was to investigate how to establish and evaluate the successful model of total limbal stem cell deficiency (LSCD).Methods Twenty Japanese white rabbits aged 3-5 months were selected.The limbus corneal epithelium was removed from 1 mm inner to 2 mm outer of the limbus 100-150 μm in deep,and the total central epithelium and shallow stroma were simultaneously removed in the left eyes using scalpel.The experimental eyes were examined by slitlamp 2,3,4,5 weeks after operation,and the inflammatory score was performed according to corneal opacity,corneal neovascularization and corneal flurescein dye using international universal rating criteria of LSCD model.Cornea tissue was obtained in various time points mentioned above to examine the structural change and goblet cells.The expression of cytokeratin 3(CK3) in the cornea was detected using indirect immuno-fluorescence staining.Fisher Exact Probability method was used to compare the successful rate of models in different time points.Results The successful rate of models rate was 12.5％,62.5％,81.3％ and 87.5％,respectively 2,3,4,5 weeks after operation,showing a significant difference between the 3-week group and 2-week group (P =0.009).However,no significant differences were found in the model successful rate between the 3-week group and the 4-week group,the 4-week group and the 5-week group (P =0.465,0.200).There was a little difference between the 3-week group and the 5-week group(P=0.049).The mean time of achieving successful model was(3.21 ±0.80) weeks.The result of hematoxylin & eosin staining showed the edema of cornea stroma,a mass of inflammatory cells infiltration and new vessels.Goblet cells could be found by Periodic acid-Schiff staining 5 weeks after operation.Expression of CK3 was absent in the corneas of successful model eyes.Conclusions The LSCD model can be successfully established by cutting off the epithelium of limbus and central cornea,and the average time of model formation is about 3.2 weeks.

Objectives To explore the differences in therapeutic efficacy between decitabine combined with low dose HAG(D+ HAG)and CAG in elderly patients with acute myeloid leukemia (AML).Methods Totally 32 elderly patients with AML in our department from July 2012 to July 2015 were retrospectively analyzed.15 patients were on a therapy of decitabine combined with low dose HAG,and 17 patients with CAG.Efficacy and side effects were compared between the two groups.Results In(D+HAG)versus CAG groups,the complete remission(CR)was 10 cases(66.7％)vs.6 cases (35.3 ％),partial remission(PR) was 2 cases (13.3％) vs.1 case(5.9 ％),non-remission(NR) was 3 cases(20％)vs.10 cases(58.8％),and the total efficacy rate(CR+PR)was 80％vs.41.2％ (P＜0.05).The side effects in two groups mainly included bone marrow depression,respiratory tract infection,gastrointestinal reaction,which were all alleviated after symptomatic treatments.The incidence rate of side effects had no statistical difference (P ＞ 0.05).Conclusions The treatment of decitabine combined with low dose of HAG is prior to CAG,and the side effects are all tolerated.So decitabine combined with low dose of HAG can be served as the first-line therapy for elderly AML patients.

OBJECTIVETo investigate the prognostic factors for non-small cell lung cancer(NSCLC)in patients under 40 years of age.

METHODSThe clinicopathological data of 148 young patients with NSCLC were retrospectively analyzed. Kaplan-Meier and Cox regression analyses were used to analyze the relationship between prognostic factors and survival time.

RESULTSThe patients were followed-up for 6 - 148 months, and the follow-up rate was 100%. In the whole group, 122 patients died and 26 cases were surviving. The 1-, 3- and 5-year survival rates were 54.7%, 10.4% and 5.6%, respectively. The median survival time (MST) was 14.7 months. Kaplan-Meier analysis showed that Karnofsky performance status (KPS), clinical stage, treatment modality and serum CEA were related with prognosis (P < 0.05). Multivariate analysis indicated that KPS, clinical stage, treatment modality and serum CEA were independent prognostic factors (P < 0.05).

CONCLUSIONSKPS, CEA, clinical stage and treatment modalities are independent prognostic factors in young NSCLC patients.
