Objective:To observe the clinical effect of Governor Vessel-regulating and brain-unblocking acupuncture on post-stroke depression.
Methods:A total of 70 eligible cases were randomly allocated into an observation group and a control group according to the random number table. Patients in the observation group were treated with Governor Vessel-regulating and brain-unblocking acupuncture, whereas patients in the control group were treated with oral Escitalopram Oxalate tablet. The treatment lasted for 8 weeks. The Hamilton depression scale (HAMD), Montgomery Asberg depression rating scale (MADRS), and Barthel Index (BI) were used to evaluate the patients’ condition before, 4 weeks and 8 weeks after treatment respectively. In addition, adverse reactions were also recorded.
Results:After 4 weeks of treatment, the HAMD and MADRS scores were significantly decreased in both groups (P<0.05); and the BI scores were significantly increased in both groups (P<0.05). There was no between-group statistical difference in HAMD score (P>0.05); the MADRS score in the observation group was significantly lower than that in the control group (P<0.05) and the BI score in the observation group was significantly higher than that in the control group (P<0.05). After 8 weeks of treatment, there were no between-group statistical differences in all aspects (P>0.05); however, the adverse reactions in the observation group were significantly less than those in the control group.
Conclusion:The Governor Vessel-regulating and brain-unblocking acupuncture is safe and effective for post-stroke depression and can obtain similar efficacy as Escitalopram Oxalate tablet. In addition, it can fast alleviate core symptoms of depression and improve the activities of daily living (ADL) and has fewer adverse reactions.

Based on the theory of the rise and fall of qi-blood in meridians, Professor GAO Yu-chun harmonizes the qi-blood and yin-yang for diagnosis and treatment of hypertersion from liver, spleen and kidney. With reference of the academic idea of“Preventive Acupuncture”, he investigated the qi and blood, treated diseases in the upper part by managing the lower part, pay attention to the syndrome differentiation of excess and deficiency, the different of acupoint property, and the treatment of acupuncture or moxibustion. Thus, through balancing yin and yang, the qi and blood are regulated to reach the therapeutic aim of“yin and yang in equilibrium”.

Objective:To study the role of 14-3-3εand Cdc25B in germinal vesicle (GV)-stage arrest of mouse oocytes,and to pay foundation for further study on the molecular mechanism of PKA/Cdc25B/14-3-3εpathway in GV-stage arrest of mouse oocytes.Methods:The eukaryotic expression vectors of pcDNA3.1-ZEO-HA-14-3-3ε, pcDNA3.1-MYC-Cdc25B-WT, pcDNA3.1-MYC-Cdc25B-S321A, and pcDNA3.1-MYC-Cdc25B-S321D were transcribed into mRNA invitro.The mouse GV-stage oocytes were collected after superovulation and divided into no injection group,TE buffer microinjection group,14-3-3εmRNA injection group,14-3-3εmRNAs + Cdc25B-WT mRNA injection group,and 14-3-3εmRNA + Cdc25B-S321A mRNA injection group,14-3-3εmRNA+Cdc25B-S321D mRNA injection group.The protein expression levels of HA-14-3-3εand MYC-Cdc25B and the phosphorylation status of Cdc2-pTyr15 were observed by Western blotting method.The morphological changes and germinal vesicle breakdown (GVDB)rates of mouse oocytes were observed under phase-contrast microscope. Results:None of the oocytes in no injection group, TE buffer microinjection group, 14-3-3εmRNA injection group,14-3-3εmRNA + Cdc25B-WT mRNAs injection group and 14-3-3εmRNA + Cdc25B-S321D mRNA were able to undergo GVBD until at least 20 h after injection (P>0.05 );the GVBD rates of oocytes in 14-3-3εmRNA+Cdc25B-S321A mRNA group at 1 h (5.00%±0.68%),2 h (62.00%±3.56%)and 3 h (100.00%± 0.00%)after injection were significantly higher than those in no injection group and TE buffer injection group (P<0.01);the oocytes in 14-3-3εmRNA+ Cdc25B-Ser321A mRNA group at 20 h (79.00%±2.80%)after injection progressed to MII (P<0.01).Conclusion:14-3-3εcan regulate the transition from GV to GVBD of mouse oocytes by means of phosphorylation and dephosphorylation of S321-Cdc25B.

Objective To study the expression and regulation characteristics of aquaporin water channel(AQP) of cerebuller metastatic tumor and brain tissue surrounding tumor and to understand the role of abnormal expression of AQP in formation and elimination of brain edema.Methods The tumor tissue specimens from five lung adencarcinoma brain metastasis cases after surgical resection were accessed.The total RNA was extracted,and RT-PCR,immunohistochemical staining were progressed to study the expression and regulation characteristics of AQP.The average gray values of near and far regions from tumor tissue were measured with HPIAS-1000 cells measuring procedure to compare actual expression quantity of AQP.Results AQP4 had a high expression in the peritumoral brain tissue and no expression in the center of brain metastasis tumor organization.The AQP4 staining was junior in the more distant region from tumor and it added significantly in the region close to the tumor tissue.Stained AQP1 was not found in cerebullar metastatic tumor and peritumoral brain microvascular endothelial cells.Conclusion The expression of AQP4 is increased significantly in the region next to the cerebullar metastatic tumor tightly.It is probably related to the formation of peritumoral brain edema.The negative expression of AQP1 might not be conducive to the removal of edema in the interspace of nerve cells.

Post-stroke aphasia refers to acquired language disorder caused by cerebrovascular disease.As part of cognitive function,language is closely related with other non-linguistic cognitive function.In recent years,many scholars have begun to pay attention to the relationship between language disorder and non-verbal cognitive function in patients with post-stroke aphasia.This paper describes the epidemiology of cognitive impairment in patients with post-stroke aphasia,and summarizes the relationship between language obstruction and the non-language-based cognitive function in patients with aphasia after stroke (such as working memory,attention,execution,etc.) to provide a direction for further research.

Objective:To observe the effect of Governor Vessel-unblocking and mind-calming acupuncture on insomnia and further develop the academic idea on Gao’s lineage acupuncture. Methods:A total of 68 insomnia cases were randomly allocated into an acupuncture group (n=34) and a medication group (n=34) according to their sequences of consultation. Patients in the acupuncture group received acupuncture treatment once a day, 5 d a week, for 4 weeks. Patients in the medication group took 1 mg of Estazolam before sleep for each dose, one dose a day, for 4 weeks. Before and after treatment, the sleep quality was evaluated using the Pittsburgh sleep quality index (PSQI), and the efficacy was assessed using the PSQI reductive rate. Results:After treatment, the global PSQI score and scores of each component in the acupuncture group were significantly decreased (allP<0.01). The global PSQI score in the medication group was significantly decreased (P<0.01). Except for sleep disturbance, scores of the rest of components were significantly decreased (P<0.01 orP<0.05). The between-group difference was statistically significant in global PSQI score (P<0.01). Except for sleep latency and duration, scores of the sleep quality, efficiency, disturbance and daytime dysfunction in the acupuncture group were significantly lower than those in the medication group (allP<0.05). In addition, the recovery and marked effect rate in the acupuncture group was significantly higher than that in the medication group (P<0.05). Conclusion:The Governor Vessel-unblocking and mind-calming acupuncture is safe, reliable for insomnia and has better efficacy than Estazolam.

Objective:To evaluate the identification rate of separating gel or HB&L pretreatment methods of MALDI-TOF-MS, thereby to provide a new idea for the rapid and accurate identification of pathogens of bloodstream infections in daily clinic practice.Methods:A total of 149 alarmed positive blood culture samples of single bacterial infection by routine laboratory methods were collected between January to December 2020 from the Sixth Medical Center, Chinese PLA General Hospital. Samples were pretreated with the separation gel accelerating tube method or the HB&L microbial culture system, followed by direct MALDI-TOF MS bacterial identification, the identification rates of the two pretreatment methods were compared and results from the traditional method were used as the standard control.Results:Among the 149 positive blood culture samples, 47.0% (70/149) were gram-negative (G -) bacteria and 53.0% (79/149) were gram-positive (G +) bacteria. Identification rate of G -strain level was 78.6% (55/70) by serum separation gel coagulation tube method and 91.4% (64/70) by HB&L microbial culture system, the difference was statistically significant ( P=0.033). Identification rate of G +strain levels was 73.4% (58/79) by serum separation gel coagulation tube method and 87.3% (69/79) by HB&L microbial culture system, the difference was statistically significant ( P=0.028). For G -bacteria in the range of 3.000-2.300, the identification rate was 22.9% (16/70) by serum separation gel accelerating tube method and 38.6% (27/70) by the HB&L microbial culture system, the difference was statistically significant ( P=0.044). For G +bacteria in the range of 3.000-2.300, the identification rate was 19.0% (15/79) by serum separation gel accelerating tube method and 34.2% (27/79) by the HB&L microbial culture system, the difference was statistically significant ( P=0.031). Conclusion:The identification rate of HB&L microbial culture system is higher than that of serum separation gel coagulation tube method. Direct MALDI-TOF MS identification of pathogenic bacteria in positive blood culture samples after pretreatment is feasible in daily clinical practice.

Methods Eighty-four cases conformed to the criteria for the diagnosis of septic shock admitted to Department of Critical Care Medicine of Xuzhou Central Hospital were randomly divided into conventional treatment group (42 cases), and SFI treatment group (42 cases). Conventional treatment was given in the two groups;in SFI treatment group, SFI 100 mL was additionally given by trace continuous intravenous pump 20 mL/h, twice daily for 7 days. Before and after treatment for 1, 6, 12, 24, 48, 72 hours, the levels of hemodynamic status, lactic acid and dosage of vasoactive drugs used, organ function, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score, the time of weaning from ventilator, the length of stay in intensive care unit (ICU), time without organ failure and 28-day mortality rate were observed. Results Compared with those before treatment, after treatment in the two groups, the mean arterial pressure (MAP), cardiac index (CI) and systemic vascular resistance index (SVRI) were increased, while the levels of heart rate (HR) and lactate were decreased (all P<0.05). Compared with conventional treatment group, in SFI treatment group, after treatment for 24 hours, the MAP level was increased significantly [mmHg (1 mmHg=0.133 kPa):75.40±9.75 vs. 71.80±11.08, P < 0.05], that continued to 48 hours; after treatment for 6 hours, the CI level was increased obviously (mL·s-1·m-2: 75.18±34.84 vs. 67.35±39.34, P < 0.05) , that continued to 48 hours; after treatment for 6 hours, the lactic acid level was decreased markedly (mmol/L: 2.03±0.82 vs. 2.24±0.97, P < 0.05);in the comparison of dosage of vasoactive drugs used between two groups, the difference was not significant (all P >0.05). Compared with that before treatment, in the conventional treatment group after treatment for 1 and 3 days, gamma glutamyl transpeptidase (GGT) was increased, on the 5th day it began to decrease, reaching its minimum on the 7th day (U/L:26.75±16.74 vs. 46.96±25.85);while in SFI treatment group, GGT was increased after treatment for 1 day, on 3rd day it began to decrease, reaching its lowest level on the 7th day (U/L:22.41±17.87 vs. 51.23±27.74);aspartate aminotransferase (AST), total bilirubin (TBil), oxygenation index (PaO2/FiO2) were increased after the treatment for 1, 3, 5, 7 days, and blood urea nitrogen (BUN), creatinine (Cr) were decreased at different time points after treatment. In the conventional treatment group, the precursor protein (PA) was decreased after treatment for 1, 3, 5 days, on the 7th day it was increased (mg/L:134.20±63.44 vs. 115.70±45.96);while in SFI treatment group, after the treatment for 1 days and 3 days, it was decreased, on the 5th day it was increased, reaching its highest level on the 7th day (mg/L:145.40±59.75 vs. 108.20±54.34). Compared with those before treatment, after treatment for 1, 3, 5, 7 days, APACHEⅡscore and SOFA score were decreased in the two groups, but there was no statistically significant difference in APACHEⅡscore between the two groups, in SFI treatment group after treatment for 3 days, SOFA score was significantly lower than that of the conventional treatment group (6.31±3.86 vs. 7.14±4.03, P<0.05), that continued to the 7th day after treatment. In SFI treatment group, the time for weaning from ventilator (days:7.5±3.5 vs. 9.1±3.2) and the length of stay in ICU (days: 16.1±9.2 vs. 18.7±8.3) were significantly shorter than those in conventional treatment group (both P<0.05). There were no significant differences in time without organ failure (days:14.5±4.2 vs. 15.3±3.1) and 28-day mortality rate [28.6%(12/42) vs. 31.0%(13/42)] between SFI group and conventional group (both P>0.05). Conclusion The combined use of SFI and EGDT can improve hemodynamics, reduce damage to vital organs, and shorten the times for ventilation and stay in ICU in septic shock patients.
