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 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.

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.

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.
