Through collecting the relevant records of "brain" in ancient traditional Chinese medicine literature, the potential structure and function of the "motor system of brain-meridian-muscle region" and "perception system of brain-meridian-cutaneous region" of the human body are analyzed preliminarily. In view of the characteristics of the symptoms of stroke sequela, focusing on the differentiation of disease location and associated with the identification of disease property, the pathogenesis of stroke is determined, "malnutrition of the sea of marrow, dysfunction of meridian muscle region and disharmony of the nutrient and the defensive in the meridian cutaneous region", while, the basic principle of treatment is formulated, "filling up the marrow, replenishing the brain, regulating meridian muscle regions, tonifying qi and facilitating blood circulation in meridians and collaterals". Based on the above, the acupoints selected in treatment and the techniques of acupuncture and moxibustion are clarified. This article presents the references for the clinical practice of acupuncture and moxibustion and provides the individual therapeutic regimen for stroke patients.

ObjectiveTo investigate the clinical features and prognosis of culture-negative liver abscess (CNLA) versus culture-positive liver abscess (CPLA), and to provide a reference for early diagnosis and effective treatment. MethodsA retrospective analysis was performed for the clinical data of 371 patients with liver abscess who were admitted to The Second Affiliated Hospital of Air Force Medical University from 2005 to 2018, among whom 145 (39.1%) had positive results of pathogen test (CPLA group) and 226 (60.9%) had negative results (CNLA group). The two groups were compared in terms of clinical features, laboratory examination, imaging data, and prognosis. The t-test was used for comparison of normally distributed or approximately normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsCompared with the CNLA group, the CPLA group had a significantly older age (t=-3.464, P=0.001) and a significantly higher proportion of patients with diabetes (χ2=17.362, P＜0.001) or cardiovascular disease (χ2=10.827, P=0.001), and compared with the CPLA group, the CNLA group had a significantly higher proportion of patients with AIDS (χ2=4.354, P=0.037). Compared with the CNLA group, the CPLA group had significantly greater increases in leukocyte count, percentage of neutrophils, alkaline phosphatase, gamma-glutamyl transpeptidase, and total bilirubin (U=20393, 19711, 18586, 19349, and 18496, all P＜0.05), a significantly greater reduction in albumin (t=3.348, P=0.001), and a significantly higher proportion of patients with a baseline APACHE Ⅱ score of ≥16 (χ2=9.550, P=0.002). Compared with the CNLA group, the CPLA group had a significantly higher proportion of tumors with a diameter of ＞5 cm (χ2=53.61, P＜0.001). In the CNLA group, 19.9% of the patients were treated with anti-infective therapy alone, while for both groups, anti-infective therapy combined with ultrasound- or CT-guided percutaneous drainage was the main treatment method. There were no significant differences in the length of hospital stay, recurrence rate, and mortality rate between the two groups (all P＞0.05). ConclusionCompared with CPLA patients, CNLA patients tend to have a younger age and are less likely to develop severe inflammatory response and liver insufficiency, with a smaller diameter of abscess which is less likely to be treated by percutaneous drainage, while there is no significant difference in prognosis between CPLA patients and CNLA patients.

Objective To investigate the role of combined analysis of E2F3a and CASP8AP2 expression in prognosis evaluation in pediatric acute lymphoblastic leukemia (ALL). Methods The study included 141 newly diag-nosed pediatric ALL patients enrolled at the Hematology Center,Beijing Children′s Hospital,Capital Medical Universi-ty between March 2008 and July 2010,including 97 boys and 44 girls(aged 1. 2 - 15. 5 years,median 5. 2 years). E2F3a and CASP8AP2 expressions were quantified in 141 children with ALL by adopting real - time quantitative poly-merase chain reaction (qPCR). Receiver operating characteristic (ROC)curve was used to find the best cut - off point to divide the patients into E2F3a or CASP8AP2 low - and high - expression groups,and the treatment outcome between the groups was compared. Cox regression was used to analyze the prognostic significance of the combined expression of E2F3a and CASP8AP2. Results The estimated 5 - year relapse free survival(RFS)rate,event free survival(EFS) rate and overall survival (OS)rate of patients with low - E2F3a and low - CASP8AP2 expression were (58. 9 ± 10. 0)％,(56. 0 ± 9. 9)％ and (72. 0 ± 9. 0)％,respectively. They were significantly lower than those of patients with high - E2F3a and high - CASP8AP2 expression,whose RFS,EFS and OS were (94. 9 ± 2. 5)％,(93. 7 ± 2. 7)％ and (96. 2 ± 2. 2)％,and the differences were all statistically significant(all P < 0. 05),respectively. Compared with other patients,the one with low expression of both E2F3a and CASP8AP2 had a poorer prognosis. In addition to MLL rear-rangements and minimal residual disease level at the end of remission induction,low expression of both E2F3a and CASP8AP2 remained as independent prognostic factors. Conclusion Low expressions of E2F3a and CASP8AP2 pre-dict poor prognosis in pediatric ALL. Combined assessment of E2F3a and CASP8AP2 expression could predict poor prognosis and relapse more accurately.

Objective To analyze the risk factors of respiratory depression occurring during recovery period in patients after having undergone general anesthesia and laparoscopic operation.Methods A total of 374 patients after general anesthesia and laparoscopic surgery admitted to the First Affiliated Hospital of Wenzhou Medical University from June 2015 to June 2016 were enrolled, they were divided into with or without the incidence of respiratory depression two groups by whether or not respiratorydepression, with the incidence of respiratory depression group 52 cases, without the incidence of respiratory depression group 322 cases. The patients' gender, age, body mass index (BMI), operation time, anesthesia maintenance mode, artificial airway mode, operative type and medication used in operation, intra-operative hypotension presence or absence, and type of operation were recorded. Univariate and multivariate logistic regression analyses were used to evaluate the risk factors of respiratory depression occurring in the recovery period after general anesthesia; receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of age, intraoperative medication, and age combine with intraoperative medication respectively in the occurrence of respiratory depression during recovery period after general anesthesia and lapatoscopic operation.Results Univariate analyses showed that there were no statistical significant differences in gender, BMI, operation time, anesthesia maintenance mode, artificial airway mode, intra-operative hypotension presence or absence, type of operation, etc. compared between patients with and without the incidence of respiratory depression groups (allP > 0.05); while the differences were statistically significant in age and drug used in the operation (dezocine, flurbiprofen, dexmedetomidine or dezocine combined with dexmedetomidine, allP < 0.05). Multivariate analyses showed that age and medication used in operation were the independent risk factors for the occurrence of respiratory depression during the anesthesia recovery stage (P values being 0.000, 0.002 respectively). ROC curve showed that age, intra-operative medication and age combine with intraoperative medication respectively had certain predictive value for the occurrence of respiratory depression during the recovery period after general anesthesia and laparoscopic surgery, the area under the ROC curve (AUC) of age combine with intraoperative medicationfor prediction of occurrence of respiratory depression during recovery period after anesthesia and laparoscopic surgery was significantly larger than that of single age or single intraoperative medication (0.826 vs. 0.668, 0.750,P < 0.01), 95% confidence interval (95%CI) of age, intraoperative medication and age combined with intraoperative medication were 0.598-0.738, 0.670-0.830, 0.764-0.888, the sensitivity, specificity and accuracy rate of age combine with intraoperative medication were 53.8%, 94.4% and 88.8%, respectively.Conclusion Elderly patients undergoing general anesthesia and laparoscopic operation and dezocine, dexmedetomidine or dezocine combined with dexmedetomidine being applied in the laparoscopic operation are more easily associated with incidence of respiratory depression during recovery period of anesthesia.

OBJECTIVE: To screen aptamers binding CD33+/CD34- cells from patients with acute myeloblastic leukemia M2 subtype (AML-M2). METHODS: CD33+/CD34- cells from patients with AML-M2 were taken as targeted cells, CD33+/ CD34- cells from normal people were taken as anti-selecting cells, and aptamers in the single strand deoxyribonucleic acid (ssDNA) library were then selected repeatedly by cell-systematic evolution of ligands by exponential enrichment (C-SELEX) technology, and amplified by polymerase chain reaction (PCR) to generate sub-ssDNA library. During the experiment, PCR amplification with fluorescently labeled primer and flow cytometry were performed to analyze the aptamers'enrichment of sub-library, and the final round product of the sub-ssDNA library was cloned. After the sequencing, the primary and secondary structures of the aptamers were analyzed. RESULTS: Electrophoresis indicated that the product of PCR amplification for each round subssDNA library was able to see a clear DNA band in the agarose gel. After 13 rounds of screening, the fluorescence intensity of the sub-ssDNA library binding the cells ranged from 2.14% to 51.12%, reaching a steady state at the 13th round. A total of 30 clones were selected and sequenced, 22 of which contained 1 of the 4 conserved sequences of AAGTA, TATCT, AGATG and AAATT in their primary structure, but the remained eight aptamers contained none of the conserved sequence. Secondary structure analysis indicated that four stem-loops and loop simulation convex structures existed in the aptamers. CONCLUSION C-SELEX technology can be used to screen the aptamers binding primary cells from patients with leukemia. The aptamers selected from the CD33+/CD34- cells from the patients of AML-M2 subtype might be used for the diagnosis and treatment for leukemia.
