Effect of Modified Shoutaiwan on Recurrent Abortion Due to Prethrombotic Status and Effect on Coagulation Factors / 中国实验方剂学杂志

Objective::To observe the efficacy of modified Shoutaiwan on recurrent abortion due to prethrombotic status with kidney deficiency and blood stasis and investigate its effect on coagulation factors. Method::The 100 cases were randomly divided into control group and observation group, 50 cases in each group. Bushen Yangxue capsule + enoxaparin sodium were given in control group, while modified Shoutaiwan + enoxaparin sodium were given in observation group, with a treatment course of 60 d in both groups. The serum clotting factor activated protein S (PS), activated protein C (PC), platelet aggregation function (PAF), platelet aggregation rate (PagT), antithrombin (AT), lupus anticoagulant material positive positive predictive value (LA), anti cardiolipin antibody positive rate of positive predictive value (ACA), plasminogen activator inhibitor-1(PAI-1), tissue factor (TF), fibrinogen (Fig), fibrinogen (FIB), fibrinogen alpha granule membrane glycoprotein-140 (GMP-140), fibrinogen fragment (F1+ 2), tissue fibrinogen activation factor (t-PA), D-dimer (D-D), activated partial thromboplastin time (APTT), prothrombin time (PT), and thrombin time (TT) were observed. Clinical efficacy, pregnancy rate, traditional Chinese medicine(TCM) syndromes and adverse reactions were compared between the two groups. Result::4 cases withdrew from the study. The total effective rate in observation group was 97.9% (48/49), higher than 85.1% (40/47) in control group (χ2=5.713, P<0.05). The pregnancy rate in observation group was 89.8% (44/49), higher than 70.2% (33/47) in control group (χ2=6.351, P<0.05). The score of traditional Chinese medicine syndromes in observation group was lower than that in control group. The indexes of PS, PC, AT, TF, Fig, FPA, APTT and TT in observation group were significantly higher than those in control group (P<0.05), while PAF, PagT, LA, ACA, PAI-1, PAP, TAT, FIB, GMP-140, F1+ 2, t-PA, D-D and PT were lower than those in control group (P<0.05). The incidence of adverse reactions in observation group was 10.2% (5/49), lower than 35.4% (17/48) in control group (P<0.05). Conclusion::Modified Shoutaiwan can effectively improve the clinical symptoms of recurrent abortion due to prethrombotic status and improve the coagulation factors in patients with kidney deficiency and blood stasis.

Aspiration Screening Tools after Stroke: A Systematic Review / 中国康复理论与实践

Objective:To systematically review the relevant researches on aspiration screening tools for stroke patients. Methods:Literatures aboute stroke aspiration screening tools till December, 2018 were recalled from PubMed, Cochrane Library, Web of Science, EMbase, CNKI, Wanfang Database and China Biomedical Literature Database. Two researchers independently screened the literatures and extracted the basic information, such as the content, screening format, scoring standard and measurement characteristics. Results:A total of 25 studies were included, involving ten aspiration screening tools. The content, screening format, scoring standard and measurement characteristics of the aspiration screening tools were analysed. There was no evidence to support the tools. Conclusion:Tools would be selected according to the patient's condition, age and swallowing related characteristics.

Advance in Risk Assessment Tools for Pressure Injury of Patients with Spinal Cord Injury / 中国康复理论与实践

Spinal cord injury (SCI) is a common traumatic disease. Patients with limited mobility are prone to pressure injuries, which seriously affect the patient's rehabilitation process. The use of risk assessment scale can effectively predict the occurrence of pressure injuries. This article reviewed the pathogenesis, risk factors, and use of different risk assessment tools for patients with spinal cord injury, compared the content, assessment methods, applicable population, reliability and validity of each risk assessment scale, summarized the advantages and disadvantages of different assessment scales, and provided reference to choose the best risk assessment tool.

Comparison of two quantitation methods of circulating tumor cells in patients with small cell lung cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To establish a quantitative method to detect circulating tumor cells (CTC) in patients with small cell lung cancer, and analyze its sensitivity and stability.</p><p><b>METHODS</b>A specific primer and probe for prepro-gastrin-releasing peptide (preproGRP) was designed and a quantitative RT-PCR method was established to detect preproGRP mRNA. Cell incorporation method was used to evaluate the sensitivity. Magnetic cell sorting (MACS) was used to isolate and purify CTC from peripheral blood, and the MACS in combination with morphological diagnosis were used for cell counting.</p><p><b>RESULTS</b>The isolation rate of CTC by MACS was 30% and the lower detection limit was 5 cells per ml blood. The sensitivity of quantitative RT-PCR in detection of preproGRP mRNA in CTC was 0.64 cells per reaction, and the lower detection limit was 50 cells per ml blood, which was lower than that of MACS. However, the cell numbers calculated by Ct value was in greater accordance (about 80%) with actual cell numbers than that obtained by MACS.</p><p><b>CONCLUSIONS</b>PreproGRP quantitative RT-PCR and MACS have both advantages and disadvantages in detecting CTC of SCLC patients. MACS has a higher sensitivity, and is more favorable when CTC count is below 50 per ml blood. Meanwhile, preproGRP mRNA quantitative RT-PCR is more reliable in calculating actual cell numbers.</p>

Clinical value of CEA and CYFRA21-1 as an assessment indicator of therapeutic efficacy in advanced non-small cell lung cancer patients / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the value of carcinoembryonic antigen (CEA) or cytokeratin 19 fragment (CYFRA21-1) as an assessment indicator of therapeutic efficacy in advanced non-small cell lung cancer (NSCLC) patients.</p><p><b>METHODS</b>228 cases of advanced NSCLC with chemotherapy were enrolled into this retrospective study. The serum CEA or CYFRA21-1 levels of all patients were above the cut-off limit before treatment. The relationship between changes of tumor markers (TMs) and imaging therapeutic efficacy or progression-free survival (PFS) was analyzed, and the value of TMs in therapeutic efficacy assessment was evaluated.</p><p><b>RESULTS</b>According to RECIST criteria, partial response (PR) occurred in 40 cases, stable disease (SD) in 151 and PD (progressive disease) in 37. The cut-off values of the changes of TMs between pre- and post-treatment were determined according to the above mentioned criteria. The CEA down (D), stable (S), above (A) groups were 90, 49 and 66 cases, respectively. CYFRA21-1 down (D), stable (S), above (A) groups were 84, 26 and 37 cases, respectively. PR groups were 68.4% and 88.9% in CEA and cyfra21-1 down groups, respectively, 7.9% and 5.6% in the above groups, respectively. PD groups were 59.4% and 76.2% in CEA and CYFRA21-1 above groups, respectively. No PD cases were in the down groups. The changes of TMs in SD group were between them. Statistically significant correlations were observed between changes of TMs and imaging therapeutic efficacy (r(CEA) = 0.45, P = 0.00; r(CYFRA21-1) = 0.44, P = 0.00). PFS among different TMs groups were significantly different (all P < 0.05), which can be used to further distinguish the prognosis among SD subgroups.</p><p><b>CONCLUSION</b>Changes of TMs can be used to predict the imaging therapeutic effect and PFS of the patients, and if the SD group is divided into subgroups according to different therapeutic efficacy and prognosis, it may help the patients to receive individualized treatment.</p>
