OBJECTIVE: To compare the therapeutic effect of thunder-fire moxibustion combined with vibration training and simple vibration training on low back pain of primary osteoporosis by 's modulus of ultrasonic wave, and seek an objective evaluating method. METHODS: A total of 60 patients were randomized into an observation group and a control group, 30 cases in each one. The patients in the two groups were treated with vibration training using whole body vibration treatment bed. In the observation group, thunder-fire moxibustion was applied at Yaoyangguan (GV 3), Mingmen (GV 4), Ganshu (BL 18), Shenshu (BL 23) and Dachangshu (BL 25). The treatment was given once every other day, 3 times a week for 4 weeks. The visual analogue score (VAS), real-time shear wave elastography (RTSWE) and medical outcomes study 36-item short-form hearth survey (SF-36) were used to evaluate pain intensity, multifidus muscle tone ('s modulus) and quality of life before treatment, after 4-week treatment and 1 month after treatment. RESULTS: Compared before treatment, the VAS scores, 's modulus of multifidus muscle and 5 dimensions of SF-36 (physical condition, body pain, general health, social function and mental health) after 4-week treatment and 1 month after treatment were significantly improved in the two groups (all <0.05), the physiological role in the observation group after 4-week treatment and 1 month after treatment were improved (both <0.05). In the observation group, the VAS scores, 's modulus of multifidus muscle and 3 dimensions of SF-36 (physiological role, body pain and general health) after 4-week treatment and 1 month after treatment were superior to the control group (all <0.05). CONCLUSION The therapeutic effect of thunder-fire moxibustion combined with vibration training is superior to simple vibration training in relieving low back pain intensity and multifidus muscle tone, and improving quality of life for primary osteoporosis. RTSWE technique can be an objective examination method to evaluate pain.

Objective: To investigate smoking cessation behaviors and factors influencing it among adult community smokers in Beijing. Methods: This was a cross-sectional epidemiological study. A questionnaire survey was administered among community smokers over 18 years old, in which information on basic demographics, tobacco use, attempts to quit smoking, tobacco-related awareness, and environmental assessment of smoking cessation support were collected. Descriptive analysis was conducted on the basic information, smoking situation, and demand for smoking cessation intervention of the respondents. Two tests were used to examine the quitting attempts of respondents. Tobacco attempts was found to be correlated with socio-demographic indicators, and factors such as tobacco use, awareness of tobacco-related issues, and the smoking cessation support environment. Dual logistic regression was used to further explore the dependence of identified factors and attempted smoking cessation behavior. Results: A total of 449 respondents were enrolled in this study, 410 of them were men (91.3%). Among the respondents, 272 people (60.6%) had tried to quit smoking and 177 people (39.4%) did not try to quit smoking. Monthly income level, tobacco-related awareness, degree of surrounding people supporting smoking cessation, whether medical treatment was sought in the previous year, number of visits, whether to persuade medical staff to quit smoking in the past year, and whether smoking was given up in the past year were the identified factors. These seven factors, such as whether they have been asked about smoking, are the influencing factors in trying to quit smoking（P<0.05）. Under the logistic regression model, monthly income level (OR=1.271, 95%CI:1.081-1.493), the support of people around them to quit smoking (OR=1.251, 95%CI:1.035-1.512), and the suggestion of medical personnel in the past year (OR=2.382, 95%CI: 1.054-5.381) were found to encourage attempts to quit smoking. Conclusion Factors such as health status, environmental support, hazard perception, and economic level influence attempts to quit smoking. Lack of self-determination and other people's influence are the main reasons for failing to quit smoking. Taking community places as the basic unit of intervention combined with professional guidance of smoking cessation clinic doctors and forming an online comprehensive linkage smoking cessation hospital community intervention model is an innovative way to optimize the management of tobacco dependence.

Objective: To evaluate the prognostic factors of T1-2N0M0 esophageal squamous cell carcinoma (ESCC) treated with definitive radiotherapy. Methods: The clinical data of 196 patients with T1-2N0M0 ESCC who were treated with definitive radiotherapy in 10 hospitals were retrospectively analyzed. All sites were members of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG). Radiochemotherapy were applied to 78 patients, while the other 118 patients received radiotherapy only. 96 patients were treated with three-dimensional conformal radiotherapy (3DCRT) and 100 treated with intensity-modulated radiotherapy (IMRT). The median dose of plan target volume(PTV) and gross target volume(GTV) were both 60 Gy. The median follow-up time was 59.2 months. Log rank test and Cox regression analysis were used for univariat and multivariate analysis, respectively. Results: The percentage of normal lung receiving at least 20 Gy (V₂₀) was (18.65±7.20)%, with average dose of (10.81±42.05) Gy. The percentage of normal heart receiving at least 30 Gy (V₃₀) was (14.21±12.28)%. The maximum dose of exposure in spinal cord was (39.65±8.13) Gy. The incidence of radiation pneumonia and radiation esophagitis were 14.80%(29/196) and 65.82%(129/196), respectively. The adverse events were mostly grade 1-2, without grade 4 toxicity. Median overall survival (OS) and progression-free survival (PFS) were 70.1 months and 62.3 months, respectively. The 1-, 3- and 5-year OS rates of all patients were 75.1%、57.4% and 53.2%, respectively. The 1-, 3- and 5-year PFS rates were 75.1%、57.4% and 53.2%, respectively. Multivariate analysis demonstrated that patients′age (HR=1.023, P=0.038) and tumor diameter (HR=1.243, P=0.028)were the independent prognostic factors for OS, while tumor volume were the independent prognostic factor for PFS. Conclusions Definitive radiotherapy is a promising therapeutic method in patients with T1-2N0M0 ESCC. Patients′ age, tumor diameter and tumor volume may impact patients′ prognosis.

Objective To investigate the incidence of central line-associated bloodstream infection (CLABSI) in patients with hematopoietic stem cell transplantation (HSCT), explore risk factors for the occurrence of CLABSI.Methods Basic information of patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) who underwent HSCT in a hematology department from November 1, 2016 to October 31, 2017 was collected, incidences of original CLABSI (OCLABSI) and modified CLABSI (MCLABSI) were calculated, related risk factors were analyzed by multivariate Cox regression.Results A total of 218 patients with AML and MDS who underwent HSCT were enrolled, 19 of whom had OCLABSI and 10 had MCLABSI.Twenty-one strains of pathogens were isolated from 19 patients with OCLABSI, including 9 gram-positive bacteria, 11 gram-negative bacteria, 1 fungus;9 strains were multidrug-resistant organisms.The main risk factors for OCLABSI included the female (HR=0.088;95％CI:0.017-0.440;P=0.003), age (HR=1.560;95％CI:1.066-2.530;P=0.034), bone marrow cell transplantation only (HR=4.408;95％CI:1.860-22.593;P=0.043), ATG/CSA/MMF/MTXG for preventing graft-versus-host disease (GVHD) (HR=0.101;95％CI:0.015-0.686;P=0.019), and MTX for preventing GVHD (HR=0.097;95％CI:0.011-0.816;P=0.032).Conclusion Definition of MCLABSI can provide more accurate monitoring on deep central venous catheter-related bloodstream infection.Incidence of CLABSI in HSCT patients can be reduced by early detection of high-risk population according to high-risk factors, strict adherence to the prevention and control measures of bloodstream infection, and implementation of immune recombination after enhanced transplantation.

Objective To analyze the clinical features and genotypes of adult patients with simple virilizing form of 21-hydroxylase deficiency (SV 21-OHD).Methods This is a retrospective study including 33 patients with SV 21-OHD from January 2015 to March 2018 in the Ninth People's Hospital of Shanghai Jiao Tong University School of Medicine.Results The diagnostic age of the patients was (26.3± 6.5) years old.All patients presented with signs of masculinization,such as short stature (100％),clitoromegaly/microphallus (89.65％,26/29),undeveloped breasts (82.76％,24/29),deep voice (55.17％,16/29) and primary amenorrhea (89.65％,26/29).The serum levels of 17-hydroxyprogesterone (17-OHP),androstenedione (AD) and testosterone were significantly elevated in 90.9％,93.9％ and 91.2％ of the patients,respectively.Thirteen types of mutations were identified in CYP21A2 from these patients.Among them,I173N accounted for 40％ and I2 G accounted for 18.33％.Four patients were found with multiple mutations in CYP21A2.Conclusions Short stature,clitoromegaly/microphallus and primary amenorrhea are the most common clinical features in adult patients with SV 21-OHD.Serum levels of 17-OHP and AD are important indices for the diagnosis and monitoring of the patients.I173N and I2 G are the two most prevalent mutations in patients of the present study.Limitation of clinical recognition and delay in treatment contribute to the short stature of the SV 21-OHD patients.

In tumor immunotherapy, the study of programmed death 1 (PD-1) and programmed death ligand 1 (PD-L1) provides a new approach for the comprehensive treatment of advanced lung cancer. About 20％ of patients with non-small cell lung cancer could benefit from lung cancer immunotherapy, while those with high PD-L1 expression will benefit more. At present, there are few related studies on PD-1 expression at home and abroad, and the detection of PD-1/PD-L1 expressions is mostly concentrated in tumor tissues. With the research progress of liquid biopsy technology, the convenience and accuracy of peripheral blood testing are also receiving more and more attention. However, there are still few biological indicators for predicting the efficacy of tumor immunotherapy, and the uniform standard and accuracy of testing still need more clinical practice and exploration. This article reviews the research on the expressions of PD-1 and PD-L1 in tissues and peripheral blood of patients with lung cancer, aiming to provide reference for the treatment of lung cancer with immune checkpoint blockers.

Objective To evaluate the changes of hypoxic conditions in non-small cell lung cancer (NSCLC) patients before and after radiotherapy and assess the value of 18F-fluoromisonidzaole (FMISO)PET/CT for radiotherapy efficacy evaluation.Methods A total of 21 NSCLC patients (15 males,6 females,age 30-74 years) from January 2014 to October 2016 were prospectively enrolled.18F-FMISO PET/CT was performed before and after radiotherapy,and all patients underwent 18F-fluorodeoxyglucose (FDG)PET/CT before radiotherapy.Routine chest CT was performed at the 3rd and 6th month after radiotherapy.The maximum standardized uptake value (SUVmax) of tumor and muscle,tumor volume and hypoxic volume (HV) were measured.Tumor-to-muscle (T/M) value of 18F-FMISO was calculated,and T/M ≥ 1.3 was considered as the hypoxia cut-off value.Data were analyzed using Pearson correlation,paired t test,signed rank sum test and Wilcoxon rank sum test.Results Totally 81.0％(17/21) of NSCLC patients had hypoxia.There were significant positive correlations between 18F-FMISO T/M value and tumor volume or 18F-FDG SUVmax(r:0.72,0.60,both P＜0.05).The T/M value after radiotherapy was significantly lower than that before radiotherapy (1.42± 1.12 vs 2.08±0.71;t =3.62,P＜0.05),and median HV was also significantly lower than that before radiotherapy (6.53 vs 12.41 cm3;z =-3.83,P＜0.05).The median T/M values of effective group (n =14) and ineffective group (n =7) before radiotherapy were significantly different (2.14 vs 2.87;z=-2.27,P＜0.05),and the median HV of 2 groups before radiotherapy was also significantly different (6.43 vs 10.20 cm3;z=-2.14,P＜0.05).Conclusions Most NSCLC patients have hypoxia before radiotherapy.The larger tumor volume,the higher degree of hypoxia.Radiotherapy can alleviate the hypoxia of tumors.18F-FMISO PET/CT imaging before radiotherapy can be used to predict the efficacy of patients with NSCLC.

Objective To investigate the influence of epidural analgesia on labor duration under the new partogram recommendations using quantile regression.Methods In this study,we recruited 300 nulliparous women at full term who were hospitalized in Department of Obstetrics and Gynecology,Tongji Medical College,Huazhong University of Science and Technology from May to September,2018.The participants who were willing to receive epidural analgesia during labor were assigned to the epidural group (n=150),and those who were not to the control group (n=150).Labor duration and delivery outcomes were analyzed by Student's t test,Mann-Whitney U test,Chi-square test and Fisher's exact test.Quantile regression models were also used to investigate the effect of epidural analgesia on labor duration.Results The median durations of first-and second-stage labor in the epidural group were 600(400-840) and 66(45-98) min,respectively,which were significantly longer than those of the control group [420(320-610) and 52(33-87) min] (Z=-4.273,P＜0.001;Z=-3.210,P=0.001).Quantile regression analysis showed that,for the first stage of labor,epidural analgesia was associated with labor prolongation,and had significant effects on all the percentiles (all P＜0.05).The regression coefficients increased (95.630-285.000) correspondingly as the percentiles of the labor duration (from 10th to 90th percentiles) increased.For the second stage of labor,epidural analgesia showed a significant impact on prolongation only between the 25th and 75th percentiles (coefficients:10.000～18.143;all P＜0.05).Although the epidural group had a significant higher episiotomy rate [46.8％(65/139) vs 33.3％(48/144),x2=5.318,P=0.021],more times of urine catheterization during labor [1(0-1) vs 0(0-1),Z=-0.974,P=0.001]and higher rate of oxytocin administration during labor [48.7％(73/150) vs 30.0％(45/150),x2=10.952,P=0.001],when compared with the control group,there was no significant difference in cesarean section rate,assisted vaginal delivery rate and neonatal outcomes between the two groups (all P＞0.05).Conclusions Epidural analgesia may associated with the prolongation of the first and second stage of labor,especially with the first stage of labor,but has no adverse effects on maternal and neonatal outcomes.

Objective In this study, we aimed to detect the level of total circulating microparticles (MPs) in pregnant women with preeclampsia (PE) and analyze the proteome of MPs to explore their roles in the pathogenesis and progression of PE. Methods 98 pregnant women with PE, 54 healthy pregnant women, and 51 healthy non-pregnant women were enrolled from December 2016 to June 2018, whose MP levels were detected by flow cytometry and compared. Proteins extracted from the MPs were analyzed by high performance liquid chromatography mass spectrometry.Results The total MP level of the healthy pregnant group was significantly higher than thatof the non-pregnant group [159.87 (113.25, 218.18)/μl vs 94.10 (53.35, 140.23)/μl, P=0.004], but was not significantly different from that of the PE group. By proteomic profiling, 30 differential proteins were obtained between healthy pregnant women and healthy non-pregnant women, which were closely related to biological processes such as complements, coagulation cascades, angiogenesis and so on; 14 differential proteins were found between PE patients and healthy pregnant women, which were closely related to biological processes such as coagulation cascades, complements and inflammatory reactions, angiogenesis and so forth. Conclusions The level of circulating MPs may reflect the hypercoagulability of preeclampsia. In addition, circulating MPs may be involved in the pathogenesis of PE through various pathways by carrying different proteins, which indicates their potential value in the intervention of PE.

Objective Observing changes in thehaemostatic system to determinetheseverity and prognosis of HELLP syndrome. Methods 127 cases of HELLP syndrome diagnosed in Peking University Third Hospital were enrolled from August 2010 to August 2018. Maternal and fetaldemographic characters, postpartum complications,length of hospital stay,prothrombin time(PT),activated partial thromboplastin time (APTT), Fibrinogen(Fg) and D-Dimer(D-D) were collected. Results There was no statistical difference inparturient PT, APTT, D-D levels between maternals of HELLP syndrome with and without postpartum hemorrhage,which were [9.6 (9.0, 11.5)s vs 9.4 (8.9, 9.7)s, P=0.243], [30.2 (29.1, 38.3)s vs 29.8 (27.7, 31.8)s, P=0.151], and [0.80 (0.52, 4.52)μg/ml vs 0.91 (0.55, 2.48)μg/ml, P=0.923] respectively. There was a statistically significant difference obvious difference in parturient Fglevels between two groups [(2.94±1.48) g/L vs (3.61±1.00)g/L, P=0.022). The receiver operating characteristic curve(ROC) analysis showed that the AUC of fibrinogen level when estimating postpartum hemorrhage was 0.688(95％CI:0.600-0.767), cut-off value was 3.04 g/L, negative predictive value was 74.3％. There was a negative correlation between parturient Fg and days of hospital stay of HELLP syndrome maternal(r=-0.182, P=0.040). There was no statistical difference in parturient PT, APTT, Fg and D-D levels between the fetal survival group(n=93) and non-survival group (n=34), and between the distressed group (n=23) and he undistressed group(n=70) (P>0.05). Conclusions The low parturient Fg level may be a risk factor of maternal adverse clinical outcomes in HELLP syndrome. Maintaining the Fg at a stable level may reduce the incidence of HELLP syndrome adverse outcomes.
