Analysis of solute carrier organic anion transporter family member 1b1 and apolipoprotein E genes in a population from southern Yunnan / 中国基层医药

Objective:To analyze the distribution of solute carrier organic anion transporter family member 1b1 ( SLCO1B1) and apolipoprotein E ( ApoE) genes in a population from southern Yunnan. Methods:The data of 104 patients who received treatment in Southern Central Hospital of Yunnan Province (The First People's Hospital of Honghe State) between May 2019 and June 2020 were collected. The distribution of SLCO1B1 and ApoE genes and their relationship with nationality, sex, and age were analyzed and compared between different regions. Results:The percentage of patients carrying *1a/*1a, *1a/*1b, *1b/*1b, *1a/*15, *1b/*15, five phenotypes of SLCO1B1 gene, in the population from southern Yunnan was 4.81%, 32.69%, 42.31%, 12.50% and 7.69% respectively. Phenotypes *1a/*5, *5/*5, *5/*15 and *15/*15 were not detected. Normal metabolic phenotype of SLCO1B1 accounted for 79.81%, and intermediate metabolic phenotype of SLCO1B1 accounted for 20.19%. Weak metabolic phenotype was not detected. The percentage of patients carrying E2/E2, E2/E3, E3/E3, E3/E4, E4/E4, five phenotypes of ApoE gene in the population from southern Yunnan was 0.96%, 16.35%, 70.19%, 11.54% and 0.96% respectively. E2/E4 phenotype was not detected. The percentage of patients with ApoE protective phenotype, ApoE normal phenotype, and ApoE risk phenotype was 17.31%, 70.19% and 12.50% respectively. The observed polymorphism mutation frequency of SLCO1B1 and ApoE genes was consistent with the Hardy-Weinberg equilibrium ( P > 0.05), suggesting constancy and a population representation. The Fisher test showed that SLCO1B1 gene distribution differed significantly between ethnic minorities and Han nationality in southern Yunnan ( P = 0.013). There was no significant difference in SLCO1B1 gene distribution between different sexes and between different ages (all P > 0.05). There was no significant difference in ApoE gene distribution between ethnic minorities and Han nationality, between different sexes, and between different ages in the population from southern Yunnan (all P > 0.05). Conclusion:SLCO1B1 gene distribution is related to nationality in the population from southern Yunnan, but it is unrelated to sex and age. ApoE gene distribution is unrelated to nationality, sex and age.

Analysis and clinical significance of cytochrome P 450 2C19 gene in patients with cardiovascular and cerebrovascular diseases in southern Yunnan / 中国基层医药

Objective:To analyze the distribution and clinical significance of cytochrome P 450 2C19 (CYP2C19) gene in patients with cardiovascular and cerebrovascular diseases in southern Yunnan. Methods:The data of 245 patients with cardiovascular and cerebrovascular diseases who received treatment in Southern Central Hospital of Yunnan Province between May 2019 and June 2020 were retrospectively analyzed. The distribution of CYP2C19 gene and its relationship with nationality, age, sex, blood lipids, hypertension, and diabetes were analyzed and compared between southern Yunnan and other regions.Results:The proportions of seven phenotypes of CYP2C19 gene *1/*17, *1/*1, *1/*2, *1/*3, *2/*2, *2/*3, *3/*3 in 245 patients were 2.86%, 38.37%, 39.18%, 5.31%, 9.39%, 4.08% and 0.82%, respectively. The proportions of individuals with superfast/ultrafast metabolism, fast metabolism, intermediate metabolism, and slow metabolism in 245 patients were 2.86%, 38.37%, 44.49%, and 14.29%, respectively. The frequency of polymorphisms in the CYP2C19 gene was consistent with the Hardy-Weinberg equilibrium ( P > 0.05), which was constant and representative. The Fisher test showed that the CYP2C19 gene distribution of patients with cardiovascular and cerebrovascular diseases in southern Yunnan was not greatly correlated with nationality, age, sex, underlying disease, blood lipids, and the types of cardiovascular and cerebrovascular diseases (all P > 0.05). There was a significant difference in CYP2C19 gene distribution in patients from southern Yunnan versus Dongguan, Jiangxi, Fujian, northern Sichuan, Chifeng, Xiamen, Shaanxi, and Kunming ( P < 0.001, < 0.001, 0.045, 0.008, 0.001, 0.005, < 0.001, 0.016). Conclusion:The distribution of CYP2C19 gene in patients with cardiovascular and cerebrovascular diseases in southern Yunnan is not obviously correlated with nationality, age, sex, underlying diseases, blood lipids, and the types of cardiovascular and cerebrovascular diseases. CYP2C19 gene distribution is related to regional distribution, which can guide personalized medication in different regions.

The effect of hematoma puncture drainage before decompressive craniectomy on the prognosis of hypertensive intracerebral hemorrhage with cerebral hernia at a high altitude / 中华创伤杂志(英文版)

PURPOSE@#Rapid decompressive craniectomy (DC) was the most effective method for the treatment of hypertensive intracerebral hemorrhage (HICH) with cerebral hernia, but the mortality and disability rate is still high. We suspected that hematoma puncture drainage (PD) + DC may improve the therapeutic effect and thus compared the combined surgery with DC alone.@*METHODS@#From December 2013 to July 2019, patients with HICH from Linzhi, Tibet and Honghe, Yunnan Province were retrospectively analyzed. The selection criteria were as follows: (1) altitude ≥1500 m; (2) HICH patients with cerebral hernia; (3) Glascow coma scale score of 4-8 and time from onset to admission ≤3 h; (4) good liver and kidney function; and (5) complete case data. The included patients were divided into DC group and PD + DC group. The patients were followed up for 6 months. The outcome was assessed by Glasgow outcome scale (GOS) score, Kaplan-Meier survival curve and correlation between time from admission to operation and prognosis. A good outcome was defined as independent (GOS score, 4-5) and poor outcome defined as dependent (GOS score, 3-1). All data analyses were performed using SPSS 19, and comparison between two groups was conducted using separate t-tests or Chi-square tests.@*RESULTS@#A total of 65 patients was included. The age ranged 34-90 years (mean, 63.00 ± 14.04 years). Among them, 31 patients had the operation of PD + DC, whereas 34 patients underwent DC. The two groups had no significant difference in the basic characteristics. After 6 months of follow-up, in the PD + DC group there were 8 death, 4 vegetative state, 4 severe disability (GOS score 1-3, poor outcome 51.6 %); 8 moderate disability, and 7 good recovery (GOS score 4-5, good outcome 48.4 %); while in the DC group the result was 15 death, 6 vegetative state, 5 severe disability (poor outcome 76.5 %), 4 moderate disability and 4 good recovery (good outcome 23.5 %). The GOS score and good outcome were significantly less in DC group than in PD + DC group (Z = -1.993, p = 0.046; χ@*CONCLUSION@#PD + DC treatment can improve the good outcomes better than DC treatment for HICH with cerebral hernia at a high altitude.

Heart Rate Variability Biofeedback Increased Autonomic Activation and Improved Symptoms of Depression and Insomnia among Patients with Major Depression Disorder

OBJECTIVE: Autonomic imbalance is considered a psychopathological mechanism underlying major depressive disorder (MDD). Heart rate variability (HRV) is an index for autonomic activation. Poor sleep quality is common among patients with MDD. HRV biofeedback (BF) has been used for regulating autonomic balance among patients with physical illness and mental disorders. The purpose of present study was to examine the effects of HRV-BF on depressive symptoms, sleep quality, pre-sleep arousal, and HRV indices, in patients with MDD and insomnia. METHODS: In this case-controlled study, patients with MDD and Pittsburgh Sleep Quality Index (PSQI) score higher than 6 were recruited. The HRV-BF group received weekly 60-minute protocol for 6 weeks, and the control group who have matched the age and sex received medical care only. All participants were assessed on Beck Depression Inventory-II, Back Anxiety Inventory, PSQI, and Pre-Sleep Arousal Scale. Breathing rates and electrocardiography were also performed under resting state at pre-testing, and post-testing conditions and for the HRV-BF group, also at 1-month follow-up. RESULTS: In the HRV-BF group, symptoms of depression and anxiety, sleep quality, and pre-sleep arousal were significantly improved, and increased HRV indices, compared with the control group. Moreover, in the HRV-BF group, significantly improved symptoms of depression and anxiety, decreased breathing rates, and increased HRV indices were detected at post-testing and at 1-month follow-up, compared with pre-testing values. CONCLUSION: This study confirmed that HRV-BF is a useful psychosocial intervention for improving autonomic balance, baroreflex, and symptoms of depression and insomnia in MDD patients.

TAK-264 (MLN0264) in Previously Treated Asian Patients with Advanced Gastrointestinal Carcinoma Expressing Guanylyl Cyclase C: Results from an Open-Label, Non-randomized Phase 1 Study / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: This phase 1 dose-escalation portion of the study evaluated the safety, pharmacokinetics (PK), and antitumor activity of TAK-264 in Asian patients with advanced gastrointestinal (GI) carcinoma or metastatic or recurrent gastric or gastroesophageal junction adenocarcinoma expressing guanylyl cyclase C (GCC). MATERIALS AND METHODS: Adult patients with advanced GI malignancies expressing GCC (H-score ≥ 10) received TAK-264 on day 1 of 3-week cycles as 30-minute intravenous infusions for up to 1 year or until disease progression or unacceptable toxicity. The primary objectives were to evaluate the safety profile including dose-limiting toxicities (DLTs) during cycle 1, determine the maximum tolerated dose (MTD), and characterize the PK profile of TAK-264. RESULTS: Twelve patients were enrolled and treated with 1.2 mg/kg (n=3), 1.5 mg/kg (n=3), or 1.8 mg/kg TAK-264 (n=6). Median number of treatment cycles received was two (range, 1 to 10). None of the patients experienced a DLT and the MTD was not determined. Ten patients (83%) experienced adverse events (AEs). The most common were neutropenia, anorexia, and nausea (each reported by four patients). Five patients (42%) experienced grade ≥ 3 AEs consisting of tumor hemorrhage and hypertension, ascites, adrenal insufficiency, neutropenia and asthenia. Serum exposure to TAK-264 increased proportionally with the dose and the median half-life was approximately 5.5-6.6 days. No patients experienced an objective response. CONCLUSION: TAK-264 demonstrated a manageable safety profile with limited antitumor activity consistent with studies conducted in Western patients with advanced GI malignancies. TAK-264 exposure increased proportionally with the dose.

Management of ulcerative colitis in Taiwan: consensus guideline of the Taiwan Society of Inflammatory Bowel Disease

Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic mucosal inflammation of the colon, and the prevalence and incidence of UC have been steadily increasing in Taiwan. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of UC taking into account currently available evidence and the expert opinion of the committee. Accurate diagnosis of UC requires thorough clinical, endoscopic, and histological assessment and careful exclusion of differential diagnoses, particularly infectious colitis. The goals of UC therapy are to induce and maintain remission, reduce the risk of complications, and improve quality of life. As outlined in the recommended treatment algorithm, choice of treatment is dictated by severity, extent, and course of disease. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to immunosuppressive treatment, especially with steroids and biologic agents, and should be regularly monitored for reactivation of latent infection. These consensus statements are also based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of UC in Taiwan.

Management of Crohn's disease in Taiwan: consensus guideline of the Taiwan Society of Inflammatory Bowel Disease

Crohn's disease (CD) is a chronic relapsing and remitting inflammatory disease of the gastrointestinal tract. CD is rare in Taiwan and other Asian countries, but its prevalence and incidence have been steadily increasing. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of CD taking into account currently available evidence and the expert opinion of the committee. Thorough clinical, endoscopic, and histological assessments are required for accurate diagnosis of CD. Computed tomography and magnetic resonance imaging are complementary to endoscopic evaluation for disease staging and detecting complications. The goals of CD management are to induce and maintain remission, reduce the risk of complications, and improve quality of life. Corticosteroids are the mainstay for inducing re-mission. Immunomodulating and biologic therapies should be used to maintain remission. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to treatment and receive regular surveillance for cancer. These consensus statements are based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of patients with CD in Taiwan.

How to determine the qi arrival and its strength in clinical research / 中国针灸

Qi arrival is the meridian qi response to acupuncture stimulation. Through analyzing the relevant concepts of qi arrival and summarizing the general understanding of it in clinic and on the basis of the collection of the relevant literature at home and abroad on the determination of qi arrival and its strength, the characteristics are analyzed on the present method and the method for the determination of qi arrival and its strength is discussed in terms of the results in the needling sensation scale. It is believed that the needling sensation and its strength can be used to determine whether the qi is arrived or not and its strength. The components of different types of needling sensation are much better applicable for the analysis on the characteristics and rules on the influence on qi arrival. This method is in compliance not only with the theoretic connotation of qi arrival, but also with the clinical general understanding, which lays the foundation for the analysis on the scale results.

Effect of Acupuncture at Sanyinjiao (SP6) on the Infrared Temperature of Guanyuan (CV4) and Sanyinjiao in Dysmenorrhea Patients / 上海针灸杂志

Objective By using infrared thermal imager (Flir-SC620), to observe the effect of needling Sanyinjiao (SP6) on the skin temperature at Guanyuan (CV4) and Sanyinjiao in patients with primary dysmenorrhea (PD) of cold and dampness stagnation pattern, and to explore the probability of using infrared thermal imaging for diagnosis and as an objective index for evaluating the action and needling qi of acupuncture. Method Thirty-six subjects were recruited and divided into four group, a health control group (group A), a control group of PD of cold and dampness stagnation pattern (group B), a needling-qi-expected group (group C) and a needling-qi-unexpected group (group D). Group A and B were not given acupuncture treatment, while group C and D were treated with acupuncture at bilateral Sanyinjiao with needles retained for 30 min, and the needling sensations were recorded. The infrared thermal imager was used to detect the skin temperature at Guanyuan and bilateral Sanyinjiao for 40 min for each group, and the temperature was recorded every 10 min. The temperature during different periods of time, 0-10 min, 20-20 min, 20-30 min, 30-40 min, 0-30 min, and 0-40 min were then calculated. In group C, those obtained the needling qi sensation were further grouped into C-1 and those didn’t obtain the sensation were into C-2; in group D, those obtained needling qi sensation were further grouped into D-1 and those didn’t obtain the sensation were into D-2. SPSS 17.0 was adopted for data processing, and the data were analyzed by using MANOVA of repeated measuring. Result Compared to group A (6 cases), the temperature at Guanyuan in group B (6 cases) was significantly decreased during 0-30 min and 0-40 min (P<0.05), the temperature at the left Sanyinjiao during 0-40 min in group B was significantly decreased (P<0.05), and the temperatures at bilateral Sanyinjiao during 30-40 min in group B significantly dropped (P<0.05). Compared to group B, the temperatures at Guanyuan during 0-30 min and 0-40 min in group C1 (12 cases) and group D1 (11 cases) were significantly increased (P<0.05), the temperature at left Sanyinjiao during 0-40 min in group D1 was significantly increased (P<0.05), and the temperatures at bilateral Sanyinjiao during 30-40 min in group D1 were significantly increased (P<0.05). There was no case in group C2 and only 1 case in group D2, hence, the data were not enough for analysis. Conclusion Decrease of the infrared temperature at Guanyuan and Sanyinjiao can be taken as one of the diagnostic criteria for dysmenorrhea of cold stagnation pattern. Increase of the infrared temperature at Guanyuan can be regarded as one of the objective evidences for the along-meridian transmission characteristic in needling Sanyinjiao.

A retrospective analysis of 20-year data of the surgical management of ulcerative colitis patients in Taiwan: a study of Taiwan Society of Inflammatory Bowel Disease

BACKGROUND/AIMS: With the recent progress in medical treatment, surgery still plays a necessary and important role in treating ulcerative colitis (UC) patients. In this study, we analyzed the surgical results and outcomes of UC in Taiwan in the recent 20 years, via a multi-center study through the collaboration of Taiwan Society of IBD. METHODS: A retrospective analysis of surgery data of UC patients from January 1, 1995, through December 31, 2014, in 6 Taiwan major medical centers was conducted. The patients' demographic data, indications for surgery, and outcome details were recorded and analyzed. RESULTS: The data of 87 UC patients who received surgical treatment were recorded. The median post-operative follow-up duration was 51.1 months and ranged from 0.4 to 300 months. The mean age at UC diagnosis was 45.3±16.0 years and that at operation was 48.5±15.2 years. The 3 leading indications for surgical intervention were uncontrolled bleeding (16.1%), perforation (13.8%), and intractability (12.6%). In total, 27.6% of surgeries were performed in an emergency setting. Total or subtotal colectomy with rectal preservation (41.4%) was the most common operation. There were 6 mortalities, all due to sepsis. Emergency operation and low pre-operative albumin level were significantly associated with poor survival (P=0.013 and 0.034, respectively). CONCLUSIONS: In the past 20 years, there was no significant change in the indications for surgery in UC patients. Emergency surgeries and low pre-operative albumin level were associated with poor survival. Therefore, an optimal timing of elective surgery for people with poorly controlled UC is paramount.

Surveillance and response of hepatitis B virus in Hong Kong Special Administrative Region, 1988–2014

The World Health Organization (WHO) Western Pacific Region with an estimated 160 million chronic hepatitis B virus (HBV) carriers in 2007 bears a significant burden of HBV-related mortality and morbidity. Most Member States in the region have an estimated chronic HBV infection proportion of more than 8% in their adult population, which is the highest worldwide. The WHO Regional Office for the Western Pacific published the first Regional Plan for Hepatitis B Control in January 2003. This plan is updated periodically with a consistent ultimate goal of achieving a chronic HBV infection rate of less than 1% in the region. Viral hepatitis is a statutorily notifiable disease in Hong Kong Special Administrative Region (SAR). The Central Notification Office of the Department of Health receives notifications with pre-defined case definitions. In July 2011, Hong Kong SAR was verified by the WHO Regional Office for the Western Pacific as having successfully achieved the goal of hepatitis B control. Liver cancer was the third leading cause of cancer death in Hong Kong SAR in 2012, and evidence showed that 75–80% of liver cancer cases were related to chronic HBV infection. This report reviews the surveillance data of HBV infections in Hong Kong SAR from 1988 to 2014 and discusses the responses and existing gaps to achieve the WHO goal in the local context.

Analysis on regulating deqi in the ancient works of the late dynasties / 中国针灸

From the time of Neijing (Internal Classic) and Nanjing (Classic of Medical Problems) till the end of Qing dynasty, the medical scholars of each dynasty had taken the recognition of deqi as the subject in the stud- ies. Through the historical analysis, the content of regulating deqi was further understood in relevant ancient liter- ature. By checking the ancient works of acupuncture in each dynasty till the end of Qing dynasty, in reference to the evidences in over 10 works, such as Zhenjiu Dacheng (Great Compendium of Acupuncture and Moxibustion) , Zhenjing Zhinan (Instruction of Acupuncture Canon), Zhenjiu Daquan, and in association with the academic views of acupuncture masters in modern time, it was discovered that the medical scholars after the time of Neijing and Nanjing had enriched the understandings of deqi, such as the connection of cold and heat reaction, radiation to the affected site, reinforcing and reducing purpose in qi regulation. The methods of deqi regulations had, been explored till the end of Qing dynasty since the time of Neijing and Nanjing and the understandings of it were vari- ous among scholars.

Analysis of the Relation between Uterine Position and the Effect of Sanyinjiao (SP6) in Patients with Primary Dysmenorrhea / 上海针灸杂志

ObjectiveTo explore the relation between the uterine position and acupoint effect by analyzing the data of a clinical trial of electroacupuncture in treating primary dysmenorrhea.MethodThe uterine position was detected by ultrasonic examination;Visual Analogue Scale (VAS) was used to evaluate the pain degree before and after intervention; Retrospective Symptom Scale (RSS) was adopted to determine the improvement of symptoms.ResultThere were no significant differences in comparing the VAS score, real-time effect and post-treatment effect, and effective rate among different uterine positions (P>0.05). Electroacupuncture at Sanyinjiao (SP 6) can produce a real-time effect in releasing abdominal pain and relevant symptoms of dysmenorrhea in patients with anteversion of uterus, a less significant effect was shown in patients with retroposition of uterus, while no effect was shown in patients with uterus at middle position.ConclusionElectroacupuncture at Sanyinjiao possibly has a specific effect in releasing abdominal pain and relevant symptoms of dysmenorrhea at anteversion of uterus, and the uterine position may be related to the corresponding meridians and Zang-fu organs. The current statistical result indicates that there is no relation between the uterine position and the effect of Sanyinjiao, but this conclusion still needs proving by prospective randomized controlled clinicaltrials.

Thinking of the Qualitative and Quantitative Measurement of Needling Qi / 上海针灸杂志

Acupuncture-moxibustion theory believes that needling sensation is a crucial factor in influencing acupuncture efficacy. Judgment of occurrence of needling qi (qualitative measurement) and the intensity of needling qi (quantitative measurement) is the key section in studying the relationship between needling qi and efficacy. According to the relevant literatures, the judgment of the occurrence of needling qi mostly depended on the needling sensations, while a small amount of researches mentioned self-determined threshold or range of needling qi; the quantity of needling qi was measured by factor analysis, Massachusetts General Hospital Acupuncture Sensation Scale (MASS) based on exponential smoothing method, weighted average, addition of needling sensation score, etc. This article holds that the needling qi should be divided into two parts: overall needling qi and needling sensation components, the former referring to the occurrence and intensity of needling qi, and the latter for judging the different sensations and intensity. Currently, the studies on needling qi and efficacy should begin with single treatment at single point and multiple treatments at multiple points, to generally estimate the quality and quantity of needling qi, for seeking a qualitative and quantitative measurement in accordance with both acupuncture-moxibustion theory and clinical practice.

Quantification of Deqi (arrival of qi) by Short-latency Somatosensory Evoked Potentials：A Randomized Crossover Controlled Trial Plan / 上海针灸杂志

Objective To explore the feasibility of using short-latency somatosensory evoked potentials (SLSEP) to quantitate Deqi.Methods A randomized crossover controlled trial was carried out. Healthy subjects were enrolled and allocated to treatment (thick needle, deep insertion and manipulation for Deqi) and control (thin needle, shallow insertion and no manipulation without Deqi) groups. Somatosensory evoked potentials were recorded before, during and after acupuncture. Deqi was assessed using the score scale in the subjets. The effects of Deqi and no Deqi at point Sanyinjiao (SP 6) on the potentials were observed.Results The preliminary exploration of the feasibility by the trial test showed that the effect of Deqi on short-latency somatosensory evoked potentials had certain regularity. It was worthy to be observed.Conclusion The plan is feasible. The formal test can be conducted.

Remarks on the relationship between deqi and effect of acupuncture / 中国针灸

Acupuncturists have always paid high attention to deqi (needling sensation) in clinical. However, relationship between deqi and curative effect has not been elucidated yet. In order to have a further understanding on effect of deqi on clinical effect, through study on literature associated with deqi since the establishment of People's Republic of China in 1949, it is held that various factors can influence therapeutic effect of acupuncture treatment, including whether needling sensation appears or not, the speed of deqi, the intensity of deqi, different types of sensations as well as propagated sensation along meridians (PSM). Joint launched multidisciplinary researches should be carried out to reveal the influence principle of deqi on acupuncture effect, and to lay foundations for the further studies on mechanism of deqi.

Analysis of Mind-control and Qi-regulation:Tracing the Arrival of Qi Recorded by Nei Jing and Nan Jing / 上海针灸杂志

Objective To discuss the relationships between qi-arrival and mind-control, qi-arrival and qi-regulation, and to define qi-arrival by tracing the relevant records in Nei Jing (Classic of Internal Medicine) and Nan Jing (Classic of Difficult Issues). Method Thirty-seven relevant ancient books of the two classics were reviewed and the notes by WANG Bing, MA Shi, and YANG Shang-shan were referred. Result Mind-control requires the spirits of the practitioner, patient and environment, as well as observing and waiting for the arrival of qi. Regarding qi-regulation, theories involve that qi-arrival achieves same reinforcing and reducing effect as qi-regulation, qi-regulation is elucidated from the correct location of acupoint, proper needling depth and direction, and to regulate qi by observing the arrival of qi. Besides, the changes of internal and external environments also influence qi-arrival via qi-regulation and mind-control. Conclusion Qi-arrival is closely related to mind-control and qi-regulation in obtaining, differentiation, and adjustment. Mind-control and qi-regulation assist each other through the whole acupuncture process, which is the core of qi-arrival.

Progress on research of specificity of acupoint effects during "the 11th five-year" / 中国针灸

With retrieval in CNKI and MEDLINE data base, the articles in Chinese and English that were written by Chinese authors, which were about the specificity of acupoint effects during "the Eleventh Five-Year (2006-2010)", are included. Researchers have studied about the specificity of acupoint effects by cerebral function imaging technique and it turns out that from the perspective of central mechanism, there are differences among aupoint stimulatory effect. The curative effect of acupoints is significantly better than that of nonacupoints, different acupoints have different curative effects, the effect of disease-related acupoints is better than that of unrelated acupoints, those above have intitally proved the existence of specificity of acupoint effects. However, part of the research results need futher summaries, analysis and promotion as well as try to avoid low-level repeat in research design.
