Objective To investigate the effects of Fuzheng Quxie Prescription(mainly with the actions of supporting healthy qi and dispelling pathogens)combined with neoadjuvant chemotherapy on tumor recurrence,serum thymidine kinase 1(TK1)level and immune function in patients with triple-negative breast cancer(TNBC).Methods Eighty patients with TNBC of qi and yin deficiency type were randomly divided into a combination group and a control group,with 40 patients in each group.The control group was treated with AC-T sequential chemotherapy(Doxorubicin combined with Cyclophosphamide plus sequential Docetaxel),and the combination group was treated with Fuzheng Quxie Prescription on the basis of treatment for the control group.One course of treatment covered 21 days,and the two groups were treated for 4 consecutive courses.The changes of traditional Chinese medicine(TCM)syndrome scores,Karnofsky Performance Status(KPS)score,levels of tumor markers of carbohydrate antigen 125(CA125),carbohydrate antigen 153(CA153)and TK1,and T lymphocyte subset levels in the two groups were observed before and after the treatment.Moreover,the clinical efficacy and tumor metastasis and recurrence in the two groups were compared.Results(1)After 4 courses of treatment,the total effective rate of the combination group was 87.50%(35/40),and that of the control group was 67.50%(27/40),and the intergroup comparison(tested by chi-square test)showed that the efficacy of the combination group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the TCM syndrome scores in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the KPS scores were significantly increased compared with those before treatment(P＜0.05),and the decrease of TCM syndrome scores and the increase of KPS scores in the combination group were significantly superior to that in the control group(P＜0.05 or P＜0.01).(3)After treatment,the serum CA125,CA153 and TK1 levels of patients in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease of serum CA125,CA153 and TK1 levels in the combination group was significantly superior to that in the control group(P＜0.01).(4)After treatment,the T lymphocyte subset CD3+,CD4+ levels and CD4+/CD8+ ratio in the two groups were significantly increased compared with those before treatment(P＜0.05),and the CD8+ level was significantly decreased compared with that before treatment(P＜0.05).The post-treatment intergroup comparison showed that the increase of the T lymphocyte subset CD3+,CD4+ levels and CD4+/CD8+ ratio as well as the decrease of the CD8+ level in the combination group was all significantly superior to that in the control group(P＜0.05 or P＜0.01).(5)The one-year follow-up showed that the tumor recurrence rate and tumor metastasis rate in the combination group were 7.50%(3/40)and 12.50%(5/40)respectively,significantly lower than 25.00%(10/40)and 35.00%(14/40)in the control group,and the differences were statistically significant when comparing between the two groups(P＜0.05).Conclusion The combination of neoadjuvant chemotherapy with Fuzheng Quxie Prescription has a better therapeutic effect on TNBC patients with qi and yin deficiency syndrome,which can effectively improve the immune function of the patients,decrease the level of serum tumor markers,improve the quality of life of the patients,and reduce the incidence of tumor recurrence and metastasis.

BACKGROUND:The impact of anterior cervical surgery on the sagittal balance parameters of the cervical spine is gradually being paid attention to.Currently,there is a lack of clear and feasible clinical guidelines for the selection of surgical methods for two-level cervical spondylosis,aiming to find the most suitable fixation method that is more beneficial for this type of patient. OBJECTIVE:To compare the effects of different fusion devices for anterior cervical decompression on the changes of cervical sagittal parameters after surgery for adjacent two-level cervical spondylotic myelopathy. METHODS:A total of 44 patients with adjacent two-level cervical spondylotic myelopathy underwent anterior cervical discectomy and fusion from March 2018 to September 2020 in Liaocheng People's Hospital were retrospectively analyzed in the study,and they were divided into zero-p group(23 cases)and cage group(21 cases).All patients underwent anteroposterior X-ray,three-dimensional CT reconstruction and MRI examination before operation.At the last follow-up,the anteroposterior X-ray films of cervical spine were taken.The sagittal balance parameters of the cervical spine were measured before and after surgery,including cervical lordotic angle(C2-7 Cobb),C2-C7 sagittal vertical axis,segmented lordotic angle and T1 slope.The surgical time,intraoperative bleeding,last follow-up intervertebral fusion,and postoperative swallowing disorders were recorded,and Japanese Orthopaedic Association score on the patient was evaluated before and after surgery.The changes in cervical sagittal parameters before and after surgery were calculated and their differences were compared between the two groups. RESULTS AND CONCLUSION:(1)Both groups of patients successfully completed the surgery and received follow-up.The zero-p group had shorter surgical time and less intraoperative bleeding compared to the cage group,but the difference was not statistically significant(P>0.05).(2)The incidence rate of postoperative swallowing disorders in the cage group(7/21,33%)was higher than that in the zero-p group(3/23,13%),and the difference was statistically significant(P<0.05).(3)At the last follow-up,the clinical efficacy of the two groups was the same;all patients had bone fusion.Comparison within the group showed that the sagittal parameters of the cervical spine in both groups improved compared to before surgery(P<0.05).There was no statistically significant difference in sagittal parameters between groups(P>0.05),and there was no statistically significant difference in changes in C2-C7 sagittal vertical axis,C2-7 Cobb angle,and T1 slope between the two groups(P>0.05).However,the segmented lordotic angle changes in the zero-p group were smaller than those in the cage group,and the difference was statistically significant(P<0.05).(4)It is indicated that the use of zero-p and titanium plate combined with cage during anterior cervical discectomy and fusion surgery can effectively improve cervical sagittal balance.Titanium plate combined with cage intervertebral fusion can better reconstruct the patient's cervical lordosis and curvature.The selection of fusion devices should also comprehensively consider the occurrence of surgical complications.

Objective Recombinase-aided polymerase chain reaction(RAP)is a sensitive,single-tube,two-stage nucleic acid amplification method.This study aimed to develop an assay that can be used for the early diagnosis of three types of bacteremia caused by Staphylococcus aureus(SA),Pseudomonas aeruginosa(PA),and Acinetobacter baumannii(AB)in the bloodstream based on recombinant human mannan-binding lectin protein(M1 protein)-conjugated magnetic bead(M1 bead)enrichment of pathogens combined with RAP. Methods Recombinant plasmids were used to evaluate the assay sensitivity.Common blood influenza bacteria were used for the specific detection.Simulated and clinical plasma samples were enriched with M1 beads and then subjected to multiple recombinase-aided PCR(M-RAP)and quantitative PCR(qPCR)assays.Kappa analysis was used to evaluate the consistency between the two assays. Results The M-RAP method had sensitivity rates of 1,10,and 1 copies/μL for the detection of SA,PA,and AB plasmids,respectively,without cross-reaction to other bacterial species.The M-RAP assay obtained results for<10 CFU/mL pathogens in the blood within 4 h,with higher sensitivity than qPCR.M-RAP and qPCR for SA,PA,and AB yielded Kappa values of 0.839,0.815,and 0.856,respectively(P<0.05). Conclusion An M-RAP assay for SA,PA,and AB in blood samples utilizing M1 bead enrichment has been developed and can be potentially used for the early detection of bacteremia.

Objective To optimize the oxygen therapy regimens for infants with pulmonary diseases during bronchoscopy.Methods A prospective randomized,controlled,and single-center clinical trial was conducted on 42 infants who underwent electronic bronchoscopy from July 2019 to July 2021.These infants were divided into a nasal cannula(NC)group and a modified T-piece resuscitator(TPR)group using a random number table.The lowest intraoperative blood oxygen saturation was recorded as the primary outcome,and intraoperative heart rate and respiratory results were recorded as the secondary outcomes.Results Compared with the NC group,the modified TPR group had a significantly higher level of minimum oxygen saturation during surgery and a significantly lower incidence rate of hypoxemia(P<0.05).In the modified TPR group,there were 6 infants with mild hypoxemia,2 with moderate hypoxemia,and 1 with severe hypoxemia,while in the NC group,there were 3 infants with mild hypoxemia,5 with moderate hypoxemia,and 9 with severe hypoxemia(P<0.05).The modified TPR group had a significantly lower incidence rate of intraoperative respiratory rhythm abnormalities than the NC group(P<0.05),but there was no significant difference in the incidence rate of arrhythmias between the two groups(P>0.05).Conclusions Modified TPR can significantly reduce the risk of hypoxemia in infants with pulmonary diseases during electronic bronchoscopy,and TPR significantly decreases the severity of hypoxemia and the incidence of respiratory rhythm abnormalities compared with traditional NC.

Objective:To compare the predictive value of different cardiac ultrasound indexes in mechanical ventilation withdrawal / weaning outcome of intensive care unit (ICU) respiratory failure.Methods:Patients who received mechanical ventilation for >48 hours and were to be withdrawn due to respiratory failure in the Department of Critical Care Medicine, 921st Hospital of the People′s Liberation Army from October 2020 to March 2023 were continuously selected, and their general information, mechanical ventilation conditions, and relevant weaning inspection indicators were recorded. Left ventricular ejection fraction (LVEF), left ventricular outflow tract velocity time integral (LVOT-VTI), left heart Tei index (TI), ratio of early mitral valve diastolic peak blood flow velocity to early mitral ring diastolic peak motion velocity (E/e′) were measured by ultrasound. According to the weaning outcome, the receiver operating characteristic (ROC) curves of different cardiac ultrasound indexes were plotted to evaluate the predictive value of the withdrawal outcome.Results:A total of 83 patients were included, of which 62 were successfully withdrawn and 21 were unsuccessful. There were significant differences in mechanical ventilation time, rapid shallow breathing index (RSBI), LVEF, VTI, left cardiac TI and E/e′ between the successful group and the failed group (all P<0.05). Multivariate regression analysis suggested that mechanical ventilation time and E/e′ were independent factors affecting the outcome of patients with respiratory failure ( OR=0.603, 0.282, all P<0.05). The area under ROC curve of E/e′ predicting mechanical ventilation withdrawal/ weaning failure was 0.844(95% CI: 0.729-0.959), which was superior to the RSBI and other cardiac ultrasound indexes. Conclusions:Echocardiography has predictive value for the outcome of mechanical ventilation of respiratory failure, and E/e′, which reflects the diastolic function of the heart, is the most effective predictor, but it is not suitable for single index prediction.
