ABSTRACT
Objective:To evaluate the value of 18F-FDG uptake features in differential diagnosis of benign and malignant solitary pulmonary lesions. Methods:A total of 274 patients (181 males, 93 females, age: (61.0±10.2) years) with solitary pulmonary lesions who underwent 18F-FDG PET/CT between September 2010 and March 2017 were retrospectively analyzed. The 18F-FDG uptake features of lesions were divided into 5 types: full uptake (Group A), circular uptake (Group B), multi-focus uptake (Group C), mild uptake (Group D) and no-uptake (Group E). According to the pathology or follow-up results, the incidences of benign and malignant lesions in each group were analyzed. The diagnostic efficiencies of 18F-FDG uptake feature classification(A+ B=malignancy, C+ D+ E=benign) and SUV method (lesions with SUV max≥2.5 was taken as the malignancy) were calculated. χ2 test and ROC curve were used to analyze the data. Results:The malignant incidences of Groups A-E were 86.25%(138/160), 71.05%(27/38), 31.25%(10/32), 43.48%(10/23) and 14.29%(3/21), respectively ( χ2=79.49, P<0.001), and the rate of Group A was the highest ( χ2 values: 5.11-55.84, all P<0.05). There were significant differences in the malignancy incidence between A+ B group and C+ D+ E group (83.33%(165/198) vs 30.26%(23/76)), and between SUV max≥2.5 group and SUV max<2.5 group (76.09%(175/230) vs 29.55%(13/44); χ2 values: 71.83 and 37.15, both P<0.001). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the 18F-FDG uptake feature classification and the SUV method were 87.77%(165/188) vs 93.09%(175/188), 61.63%(53/86) vs 36.05%(31/86), 79.56%(218/274) vs 75.18%(206/274), 83.33%(165/198) vs 76.09%(175/230), 69.74%(53/76) vs 70.45%(31/44), respectively. ROC curve analysis showed that the diagnostic accuracy of the 18F-FDG uptake feature classification was higher than that of SUV method (AUCs: 0.747, 0.646; Z=4.05, P<0.001). Conclusions:18F-FDG uptake feature classification can improve the diagnostic specificity and accuracy of solitary pulmonary lesions. The multi-focus uptake feature maybe a sign of benign lesions, which still needs more researches to confirm.

ABSTRACT
Objective: To investigate the impact of different levels of systolic blood pressure on all-cause, cardiovascular and cerebrovascular mortality in patients with nonvalvular atrial fibrillation (AF). Methods: This is a prospective cohort study. Patients with AF or atrial flutter diagnosed by 12 lead electrocardiogram during physical examination of Kailuan Group employees from July 2006 to December 2017 or previously diagnosed with AF in an inpatient setting at a level 2A hospital or above were eligible for the study. Baseline clinical characteristics including age, gender, systolic blood pressure were collected. According to the level of systolic blood pressure, patients were divided into systolic blood pressure<120 mmHg (1 mmHg=0.133 kPa)group, 120 mmHg ≤ systolic blood pressure<140 mmHg group, and systolic blood pressure ≥140 mmHg group. The time of first diagnosis with AF was defined as the start of follow-up and the final follow-up ended at December 2018. Primary endpoint was all-cause death. Related information was obtained through the social security system or inpatient medical records. The cause of death was defined according to the International Classification of Diseases disease (ICD-10) codes by professional medical stuffs. Multifactorial Cox proportional risk model was used to analyze the relative risk ratios for the occurrence of death in different systolic blood pressure level groups. The relationship between systolic blood pressure levels and mortality in the patients with AF was analyzed by using natural spline function curves. Results: A total of 1 721 patients with AF were enrolled (average age=(67.0±9.0) years), patients were followed up for (6.3±3.8) years. 544 out of 1 721 patients with AF died during the follow-up period (31.61%). The cumulative incidence rate of all-cause mortality, cardiovascular and cerebrovascular death was 26.13%, 25.59%, 36.96% and 14.86%, 11.87%, 19.76% respectively in the systolic blood pressure<120 mmHg, 120 mmHg ≤ systolic blood pressure<140 mmHg and systolic blood pressure ≥140 mmHg groups. The cumulative incidence rate of all-cause, cardiovascular and cerebrovascular death was significantly higher in the group with systolic blood pressure ≥140 mmHg than in 120 mmHg ≤ systolic blood pressure<140 mmHg group (P<0.05). Compared with 120 mmHg ≤ systolic blood pressure<140 mmHg group, multivariable Cox proportional hazards regression models showed that the HRs (95%CI) for all-cause, cardiovascular and cerebrovascular death were 1.47 (1.20 to 1.79) and 1.69 (1.27 to 2.26) for the group with systolic blood pressure ≥ 140 mmHg (P<0.05). In contrast, the HRs (95%CI) for all-cause, cardiovascular and cerebrovascular death in the systolic blood pressure<120 mmHg group were 0.99 (0.73-1.35) and 1.24 (0.82-1.89), respectively, with no statistically significant differences between the two groups (P>0.05). The natural spline curve showed that there was a "U" relationship between systolic blood pressure levels and all cause death and cardiovascular and cerebrovascular death in this patient cohort. Systolic blood pressure greater than or less than 123 mmHg was associated with increased risk of death of AF patients in this cohort. Conclusion: Compared with systolic blood pressure<120 mmHg and systolic blood pressure≥140 mmHg group, the risk of all-cause and cardiovascular and cerebrovascular death is the lowest in AF patients with 120 mmHg ≤ systolic blood pressure<140 mmHg in this cohort.
ABSTRACT
Purpose@#Globally, there is a high incidence of gastric cancer (GC). Leucine zipper-EF-hand containing transmembrane protein 1 (LETM1) is reported to play a vital role in several human malignancies. However, there is limited understanding of the role of LETM1 in GC. This study aims to investigate the effects of LETM1 on proliferation, migration, and invasion of GC cells. @*Materials and Methods@#The expression levels of LETM1 in the normal gastric mucosal epithelial cells (GES-1) and GC cells were analyzed by quantitative real-time polymerase chain reaction and western blotting. CCK-8, wound healing, and Transwell invasion assays were performed to evaluate the effect of LETM1 knockdown or overexpression on the proliferation, migration, and invasion of the GC cells, respectively. Additionally, the effect of LETM1 knockdown or overexpression on GC cell apoptosis was determined by flow cytometry. Furthermore, the effect of LETM1 knockdown or overexpression on the expression levels of PI3K/Akt signaling pathway-related proteins was evaluated by western blotting. @*Results@#The GC cells exhibited markedly higher mRNA and protein expression levels of LETM1 than the GES-1 cells. Additionally, the knockdown of LETM1 remarkably suppressed the GC cell proliferation, migration, and invasion, and promoted the apoptosis of GC cells, which were reversed upon LETM1 overexpression. Furthermore, the western blotting analysis indicated that LETM1 facilitates GC progression via the PI3K/Akt signaling pathway. @*Conclusions@#LETM1 acts as an oncogenic gene to promote GC cell proliferation, migration, and invasion via the PI3K/Akt signaling pathway. Therefore, LETM1 may be a potential target for GC diagnosis and treatment.
ABSTRACT
Objective::To explore the feasibility of the rapid identification system(MALDI-Biotyper System) of microorganisms for rapid identification of Pseudomonas aeruginosa and clinical isolation of Staphylococcus aureus. Method::Identification quality control and clinical isolation were conducted for drug resistance of S. aureus by microbial rapid identification system and broth dilution method. The scores of microbial rapid identification system were compared with the MIC value of broth dilution method. The drug resistance of P. aeruginosa was simultaneously identified to determine the accuracy and applicability of the rapid identification system of microorganisms. Result::The scores of the microbial rapid identification system showed that the score of sensitive quality control strain S. aureus was higher than 2.000, and the that of resistant strain of methicillin-resistant S. aureus(methicillin-resistant S. aureus, MRSA)was between 1.700 and 2.000.The score of clinically isolated S. aureus was between 1.700 and 2.000, which suggested the drug resistance and was consistent with the MIC value of the broth dilution method. At the same time, the systemic identification value of the P. aeruginosa, which is independent of the quality control sensitive strain, was greater than 2.000, showing sensitivity and it was a sensitive strain itself, which was consistent with the results. Conclusion::The microbial rapid identification system scoring method can be used for the rapid identification of the drug resistance of S. aureus and P. aeruginosa.
ABSTRACT
Objective:To explore the clinical application value of sentinel lymph node biopsy (SLNB) in patients with early breast cancer after local excision surgery.Methods:A total of 93 breast cancer patients with clinical stage T is/T 1-2N 0M 0 who underwent SLNB and were confirmed by using tumor mass excision biopsy from March 2012 to November 2018 in Shanxi Bethune Hospital were retrospectively analyzed. According to the postoperative paraffin pathology, the patients who were successfully detected sentinel lymph node (SLN) were divided into SLN-positive group with metastasis or SLN-negative group without metastasis. The clinicopathological data were used to analyze influencing factors of SLN metastasis and SLN detection number after excision biopsy of breast masses in the two groups. Results:A total of 87 out of 93 patients were successfully detected SLN and the detection rate was 93.5% (87/93). A total of 255 SLN were detected, and the average number was 2.93 in per patient. All were subjected to rapid intraoperative freezing pathological, and 11 cases with positive SLN were detected. There were 17 patients who underwent axillary lymph node dissection (ALND), including 11 cases with positive SLN and 6 cases with SLN undetected. The paraffin pathology showed that 14 patients were confirmed as positive SLN, including 13 macrometastasis and 1 micrometastasis. The SLN false negative rate was 2.1% (3/14) of intraoperative frozen diagnosis. Univariate analysis showed that histological grade and intravascular thrombus of carcinoma were associated with SLN metastasis after breast cancer local excision; the number of SLN detection was effected by body mass index and staining method; the methylene staining method combined with radionuclide method could improve the detection rate of SLN (all P < 0.05). Multivariate analysis showed that the SLN non-detection of obesity patients was 2.651 times as much as that of normal patients (95% CI 1.592-8.194, P=0.010). Conclusion:The SLNB and appropriate tracer method will have a high SLN detection rate and better clinical application value for early breast cancer patients after breast mass resection.
ABSTRACT
Objective:To observe the effect of comprehensive rehabilitation training in a group on the speech and life quality of stroke survivors with dysarthria.Methods:Stroke survivors with dysarthria were randomly divided into an observation group (of 43) and a control group (of 41). In addition to routine medication, the control group was given 30 minutes of one-to-one rehabilitation training twice a day, 6 days a week for 4 weeks while the observation group was provided with 30 minutes of group training. Before and after the intervention, both groups were evaluated using the comprehensive dysarthria assessment scale and the WHOQOL-100 life quality assessment.Results:After the treatment, both groups′ average scores on the comprehensive assessment scale had improved significantly. Except for jaw positioning, all of the observation group′s other scores were significantly better than those of the control group, on average. The observation group also performed significantly better on the WHOQOL-100 assessment, on average.Conclusions:Group rehabilitation training can improve the speech function and life quality of stroke survivors with dysarthria significantly better than one-to-one training.
ABSTRACT
Objective:To investigate the value of 18F-prostate specific membrane antigen (PSMA)-1007 PET/CT in the detection of prostate cancer recurrence at low serum prostate specific antigen (PSA) level. Methods:From July 2018 to June 2019, 45 patients (age: 59-74 years) with suspected biochemical recurrence of prostate cancer with low PSA level (<2.0 μg/L) who underwent 18F-PSMA-1007 PET/CT examinations in Shanxi Tumor Hospital were retrospectively analyzed. Four patients with PSA<0.2 μg/L were not included in the statistical analysis due to the small sample. Among the remaining 41 patients with 0.2 μg/L≤PSA<2.0 μg/L, 10 were with 0.2 μg/L≤PSA<0.5 μg/L, 14 were with 0.5 μg/L≤PSA<1.0 μg/L, 17 were with 1.0 μg/L≤PSA<2.0 μg/L. PET/CT imaging were performed within 2 weeks after the examination of serum PSA. All patients were divided into low-moderate-risk group ( n=12) and high-risk group ( n=29) according to the National Comprehensive Cancer Network (NCCN) guidelines. χ2 test, Fisher′s exact test and Spearman rank correlation were used to analyze the data. Results:Patients were followed up for 7 (4-15) months, and all 45 patients were confirmed by pathology or follow-up. There were 31 patients with recurrence and 14 patients without recurrence. The sensitivity, specificity and accuracy were 100%(31/31), 13/14, 97.78%(44/45)respectively. One patient with PSA<0.2 μg/L presented retroperitoneal lymph node metastasis. Among 41 patients with 0.2 μg/L≤PSA<2.0 μg/L, 31(75.61%) were with at least one recurrent lesion by 18F-PSMA-1007 PET/CT. There were 20 cases of local recurrence, 13 cases of lymph node metastasis, 14 cases of bone metastasis. The detection efficacies of 18F-PSMA-1007 PET/CT were 5/10 for patients with 0.2 μg/L≤PSA<0.5 μg/L, 11/14 for those with 0.5 μg/L≤PSA<1.0 μg/L, and 15/17 for those with 1.0 μg/L≤PSA<2.0 μg/L ( χ2=4.641, P>0.05). The positive results of 18F-PSMA-1007 PET/CT were positively correlated with serum PSA value and risk group ( r values: 0.394, 0.384, both P<0.05). Conclusion:18F-PSMA-1007 PET/CT is a valuable tool for detecting biochemical recurrence of prostate cancer with low PSA level.
ABSTRACT
Objective:To observe the effect of combination of Tanreqing injection(Tanreqing) and imipenem-cilastatin on extensively-drug resistant Pseudomonas aeruginosa (XDPA), and study the mechanism of the combination. Method:The minimum inhibitory concentrations (MICs) of Tanreqing and imipenem-cilastatin against planktonic XDPA strain isolated in clinic were determined by the broth microdilution method. The checkerboard method was used to evaluate the combination effect. The bacterial metabolic activity in mature biofilm was studied by microtiter-plate test. The destructive effect of combination drugs on dynamic biofilm was observed by using BioFlux system, and viable cells were examined by confocal laser scanning microscope (CLSM) after treatment. The scanning electron microscopy (SEM) was used for observing Pseudomonas aeruginosa and length measurement. Result:The MIC values of imipenem-cilastatin and Tanreqing were 512 mg·L-1 and more than 16 500 mg·L-1. The checkerboard analysis showed that Tanreqing could enhance the sensitivity of imipenem-cilastatin, while the combination drugs synergistically inhibited the growth of bacteria. Compared with the control group or the imipenem-cilastatin individual group, the combined drugs significantly reduced the amount of living bacteria in the biofilm (PPPConclusion:Tanreqing and imipenem-cilastatin synergistically inhibit the bacterial growth in planktonic and biofilm states, and destruct biofilms.

Objective To observe the clinical effects of electro-acupuncture in surface projection zone of the pyramid decussation in treatment of migraine. Methods Totally 120 patients with migraine who met the inclusion criteria were randomly divided into four groups as projection zone group, ordinary acupuncture group, western medicine group and non-acupoint group, with 30 cases in each group. Projection zone group was treated with electro-acupuncture in pyramidal cross area (from Yuzhen to Tianzhu); Ordinary acupuncture group was treated with routine point locating according to acupuncture therapeutics; Non-acupoint group was treated with 2 inch acupoints opened beside projection zone, and 3 groups were treated with electro-acupuncture (8–20 mA, 2/100 Hz) for 30 min. Western medicine group was treated with diclofenac sodium enteric-coated table. The treatment course was 10 day. Visual Analogue Scale (VAS) score, TCM syndrome score, self-rating anxiety scale score (SAS) and self-rating depression scale score (SDS) were evaluated before and after treatment. The therapeutic effects of the four groups were compared and analyzed. Results The total effective rate of projection zone group was 93.33%, which was obviously better than the ordinary acupuncture group (86.67%), western medicine group (70.00%) and non-acupoint group (63.33%), with statistical significance (χ2=24.440, P=0.004). Compared with before treatment, the VAS score and TCM syndrome scores in the four groups after treatment decreased significantly (P<0.05). The VAS score in the projection zone group after treatment was significantly lower than the other three groups, and the TCM syndrome scores were significantly lower than the western medicine group and non-acupoint group (P<0.05). Compared with before treatment, the SDS score in the non-acupoint group and SAS and SDS scores in the other three groups decreased significantly, with statistical significance (P<0.05). SAS and SDS scores in projection zone group after treatment was significantly lower than the other three groups (P<0.05).

Objective To evaluate the prognostic value of the maximum standardized uptake value decrease proportion (△SUVmax％) on 18F-fluorodeoxyglucose (FDG) PET/CT imaging and C-MYC gene in diffuse large B cell lymphoma (DLBCL),and to find the optimal time of PET/CT imaging.Methods From September 2010 to February 2016,171 patients (87 males,84 females,average age:(50.66±2.56) years)with pathologically confirmed DLBCL were analyzed.18F-FDG PET/CT were performed before and after different courses of chemotherapy (60 patients in early phase which means 1 and 2 courses;55 patients in medium phase,3 and 4 courses;56 patients in late phase,5 and 6 courses).The region of interest (ROI) was drawn and the △SUVmax％ was calculated.Patients were evaluated with Deauville 5-point scale.Fluorescence in situ hybridization (FISH) was employed to detect C-MYC gene.Patients were followed up for 6-71 months,and progression-free survival (PFS) was calculated.x2 test,one-way analysis of variance,Kaplan-Meier analysis and Spearman correlation analysis were used to analyze the data.Results There were 42 C-MYC gene rearrangement of 171 DLBCL patients.Age,Ann Arbor stage,international prognostic index (IPI) score,serum lactate dehydrogenase (LDH) level and therapeutic response were different between patients with C-MYC gene rearrangement and those without rearrangement (x2:6.139-98.339,all P＜0.05).The optimum cutoff values of the △SUVmax％ were 62.5％,87.0％ and 92.0％ respectively in the early,medium and late phases of chemotherapy.Patients with △SUVmax％ ≥≥ 62.5％,≥ 87.0％ or ≥ 92.0％ and normal C-MYC gene showed longer PFS (x2 values:21.983-61.899,all P＜0.001).The △SUVmax％ was negatively correlated with C-MYC gene rearrangement (rs =-0.801,P ＜ 0.001).Significant differences were found in △SUVmax％ (F=6.509,P＜0.01) and Deauville 5-point scale (F=19.897,P＜0.001) among patients in early,medium and late phases.No Significant differences were shown between medium and late phases (P＞0.05).Conclusion △SUVmax％ in the different phases of chemotherapy and C-MYC gene rearrangemeut have better values for predicting the prognosis of DLBCL,and 18F-FDG PET/CT imaging should be performed between 1 course and 4 courses of chemotherapy.
ABSTRACT
AIM To determine the contents of Pb,Cd,Hg,Cu and As in vinegar-processed,wine-processed,honey-processed and steamed products of Schisandrae chinensis Fructus and to investigate their speciations.METHODS After various elements were extracted by Tessier method,the contents of Pb and Cd were determined by graphite furnace atomic absorption spectrometry,and those of Cu,As and Hg were determined by flame atomic absorption spectrometry,hydride generation-atomic fluorescence spectrometry and cold vapour atomic absorption spectrometry,respectively.RESULTS Pb content was decreased in four kinds of processed products,while Hg content was increased in them.Cd content was only increased in wine-processed product.As was only detected in wine-processed product.Cu content showed no obvious change within standard limit.Pb speciations mainly existed in ion exchange and organic binding states in vinegar-processed and wine-processed products,Fe-Mn oxidative binding and organic binding states in honey-processed product,and carbonate binding and Fe-Mn oxidative binding state in steamed product.Hg,Cu and Cd speciations mainly existed in ion exchange and carbonate binding,ion exchange and organic binding,and carbonate binding states in four kinds of processed products,respectively.CONCLUSION Different processing methods show obvious effects on the contents and speciations of five elements in Schisandra chinensis Fructus.

ABSTRACT
Objective To investigate the immediate therapeutic effect of medicated thread moxibustion on cervical spondylosis.Methods Seventy patients with cervical spondylosis meeting the inclusion criteria were randomly allocated to treatment and control groups by using random number table method, 35 cases each. The treatment group received medicated thread moxibustion and the control group, percutaneous superficial needling. The Visual Analogue Scale (VAS) score and the Clinical Assessment Scale for Cervical Spondylosis (CASCS) score were recorded in the two groups before treatment and at 30 min and 24 hrs after treatment. The clinical therapeutic effects were compared between the two groups. Results The VAS and the CASCS scores decreased significantly in the two groups at 30 min and 24 hrs after treatment compared with before treatment (P<0.05,P<0.01). There was no significantly statistical difference in comparing the VAS score between the two groups after the treatment (P>0.05). The CASCS score was lower in the treatment group than in the control group at 30 min after treatment (P<0.01) and lower in the control group than in the treatment group at 24 hrs after treatment (P<0.05). At 30 min after treatment, the clinical therapeutic effect in the treatment group was superior to that in the control group (P<0.01); at 24 hrs after the treatment, the clinical therapeutic effect in the control group was superior to that in the treatment group (P<0.05).Conclusions Medicated thread moxibustion has a definite immediate therapeutic effect on cervical spondylosis.
