Hysteroscopic Curettage Followed by Megestrol Acetate Plus Metformin as a Fertility-Sparing Treatment for Women with Atypical Endometrial Hyperplasia or Well-Differentiated Endometrioid Endometrial Carcinoma.

Background: In reproductive-aged women, the incidence of atypical endometrial hyperplasia (AEH) or endometrioid endometrial carcinoma (EEC) is rising globally. The study aimed to investigate the effectiveness of hysteroscopic curettage followed by megestrol acetate (MA) plus metformin as conservative treatment in AEH and early EEC. Methods: We retrospectively studied AEH and stage IA, grade 1 EEC patients treated with hysteroscopic curettage followed by MA (160 mg/d) plus metformin (1500 mg/d) from January 2010 to December 2020 at Fudan University Shanghai Cancer Center. Treatment outcomes were assessed by complete response (CR) rate, recurrence rate, and pregnancy outcomes. Univariate and multivariate analyses were performed via the logistic regression model. Results: The study included 79 patients, 31 (39.2%) with AEH and 48 (60.8%) with EEC. The medians of age (years) and follow-up time (months) were 30 and 39.5, respectively. Seventy-six patients (96.2%) finally achieved CR. The median time to CR was 3.6 (3.0-20.6) months. The CR rate after 3 months, 6 months, and 1 year was 55 (69.6%), 67 (84.8%), and 72 (91.1%), respectively. Recurrence occurred in 26 (34.2%) patients. Treatment duration ⩾9 months was associated with a lower recurrence rate after CR (P = .012). Fourteen (93.3%) of the 15 recurrent patients who received progestin re-treatment achieved CR again. Finally, 29 patients delivered live births. Conclusions: Hysteroscopy followed by MA plus metformin can achieve CR in short time and is overall safe. Consolidation treatment should be prolonged to decrease the recurrence rate, despite a shorter time to CR.

A "4D" systemic view on meridian essence: Substantial, functional, chronological and cultural attributes.

The term Jingluo, translated as meridian or channel, is a core component of traditional Chinese medicine (TCM) and has played a fundamental role in guiding the clinical practice of acupuncture for thousands of years. However, the essence of the meridian remains elusive and is a source of both confusion and debate for researchers. In this study, a "4D" systemic view on the essence of the meridian, namely substantial, functional, chronological, and cultural dimensions, was proposed based on a review of the ancient medical classics, recent research developments, and results from clinical practice. Previous studies have primarily focused on the substantial dimension of the meridian system, with scant interpretation about its functional domain. Neither systemic data nor evaluations have been adequately documented. Additionally, a limited but increasing number of studies have focused on the chronological and cultural dimensions. More investigations that embody the holistic concept of TCM and integrate the systemic modes and advanced techniques with dominant diseases of TCM need to be performed to obtain a more comprehensive understanding of the essence of meridians. The goal of this study is to yield useful information in understanding the essence of meridians and provide a reference and perspective for further research.

Effectiveness and Safety of Acupoint Application of Guan Xin Su He Pill () for Patients with Chronic Stable Angina Pectoris: A Multi-Center, Randomized Controlled Trial.

OBJECTIVE: To assess the clinical effectiveness of acupoint application (AP) of Guan Xin Su He Pill (, GXSHP) for patients with chronic stable angina pectoris (CSAP). METHODS: This study was carried out in 3 local hospitals in Chengdu, China. After baseline evaluation, eligible patients were randomly assigned to the placebo application for acupoints (PAA) group or the herbal application for acupoints (HAA) group. Patients in the HAA group underwent AP with herbal powder, which was mainly GXSHP, and patients in the PAA group underwent AP with sham drugs. For each treatment session, unilateral acupoints including Neiguan (PC 6), Danzhong (RN 17), Xinshu (BL 15) and Jueyinshu (BL 14), were stimulated for both groups. AP was performed 3 times a week with a 2-day interval for 4 weeks. The primary outcome was the frequency of angina pectoris attacks per week, while the secondary outcomes included angina pain intensity measured by the Visual Analogue Scale (VAS), dose of rescue oral drugs (nitroglycerin), scores on the Seattle Angina Questionnaire (SAQ), Self-Rating Anxiety Scale scores (SAS) and Self-Rating Depression Scale scores (SDS). Clinical outcomes were measured at week 0, 4 and 8. The safety of AP of GXSHP treatment for CSAP were assessed. RESULTS: A total of 121 patients were enrolled. Baseline characteristics were comparable across the 2 groups. After treatment, the angina attack numbers in the HAA group were significantly reduced from 11.00 to 4.81 (P<0.05). While, for PAA group, the angina frequency was not significantly improved (baseline 10.55; post-treatment 11.05). The HAA group had significantly fewer angina attacks than the PAA group (P<0.05). Pain intensity measured by VAS in HAA group was significantly reduced from 4.06 to 3.02 (P<0.05). While, for PAA group, the VAS was significantly increased (baseline 3.62; post-treatment 3.96; P<0.05). Clinical outcomes showed better improvement after treatment in the HAA group than in the PAA group in terms of oral administration of rescue drugs, SAS, SDS and SAQ scores (P<0.05). The adverse events were also reported. CONCLUSION: AP of GXSHP is a safe and effective treatment for CSAP patients (Registration No. NCT02029118).

[Application of keratinocytes derived from human embryonic stem cells for toxicological evaluation of drugs].

PURPOSE: To preliminarily explore the cytotoxicological responses of keratinocytes derived from human embryonic stem cells(K-hESCs) to drugs, and to provide a basis for the establishment of a new biosafety evaluation model. METHODS: CCK-8 assay was used to detect cell viability and cytotoxicity. The detection of pharmacological response was observed and compared when K-hESCs directly derived from human embryonic stem cells, human gingival epithelial cells (HGECs), and human immortalized oral epithelial cells (HIOECs) were treated with retinoic acid (RA), 5-fluorouracil(5-FU), dexamethasone(DEX), and penicillin G(PG). Statistical analysis was performed using SPSS 16.0 software package. RESULTS: After drugs were applied to HGECs, HIOEC and K-hESCs, the half inhibitory concentrations (IC50) of RA was 6.1±0.03, 5.62±0.05 and 6.58±0.02, respectively. The IC50 of 5-FU was 1.65±0.02，3.00±0.02 and 1.72±0.04, respectively. The IC50 of DEX was 113.67±0.014，328±0.002 and 126.17±0.05, respectively. The IC50 of PG was 2200±1.34，3795±2.42 and 2880±1.5, respectively. The IC50 of the four drugs between HIOEC and HGECs had significant differences(P<0.05), but there was no significant difference in IC50 between K-hESCs and HGECs(P>0.05). The IC50 of K-hESCs and HIOEC also had significant differences(P<0.05). CONCLUSIONS: IC50 of K-hESCs was closer to HGECs than HIOEC. It was speculated that K-hESCs could simulate the response of normal human cells in cytotoxicity study.

[Research status and prospects on adenosine receptor mechanism of acupuncture for myocardial ischemia].

The relationship between adenosine receptor (AdoR) and myocardial ischemia (MI), effect of acupuncture for MI and action mechanism of acupuncture improving MI by regulating AdoR are summarized. The existing researches have preliminarily reflected that the improvement of MI treated with acupuncture may be achieved by influencing the expression of AdoR. However, there are still some limitations, e.g. most of the research regimens are single-acupoint, the research results are not entirely consistent and the interaction of AdoRs are ignored, all these need to be further verified and supplemented.

Effect and Safety of CX-DZ-II Intelligent Electroacupuncture Therapeutic Instrument for Neck Pain Caused by Cervical Spondylos: Study Protocol for A Randomized Controlled Trial.

BACKGROUND: Neck pain caused by cervical spondylosis (CS) is a chronic pain condition, with an increasingly high incidence in the general population. Electroacupuncture is a common analgesic modality that has been widely applied in neck pain treatment. However, current electroacupuncture instruments used in the clinic have low intelligence levels and obscure parameter standards. We here designed this study for assessing the effect and safety of a new, intelligent electroacupuncture instrument, the CX-DZ-II, in treating neck pain. METHODS: The present study is a prospective, two-center, randomized, controlled, open-label, non-inferiority trial for CX-DZ-II on treating neck pain caused by CS. Totally 160 eligible patients will be included in this trial and randomly assigned to an experimental group and a control group in a 1:1 ratio. A semi-standard acupoint selection strategy will be employed. In the experimental group, selected acupoints will be stimulated by CX-DZ-II. Electroacupuncture treatment will be accomplished by a pre-existing electroacupuncture instrument in the control group. The duration of treatment will be 2 weeks. The primary outcome is the change of Visual Analog Scale (VAS) score after one course of treatment. The secondary outcomes include the VAS scores after each treatment, the responder rate, drug-usage rate of non-steroidal antipyretic analgesics, the rate of adverse events occurrence, and the performance of instrument. DISCUSSION: This study will evaluate the effect and safety of the CX-DZ-II intelligent electroacupuncture therapeutic instrument in comparison with a pre-existing non-intelligent instrument in the treatment of neck pain caused by CS. The results will hopefully demonstrate a more optimal electroacupuncture instrument for the treatment of neck pain. (Trial registration No. gov NCT03005301).

[Mechanism of acupoint selection along meridians to improve adenosine receptor of myocardial ischemia based on acupoint specificity].

OBJECTIVE: To explore the action mechanism of acupoint selection along meridians to improve adenosine receptor in myocardial ischemia (MI) rats by comparing the effects of acupoint selection along meridians, acupoint selection at other meridians and non-acupoint on expression of adenosine receptor. METHODS: A total of 120 SD rats were randomly divided into a blank group, a sham operation group, a model group, an acupoint-selection-along-meridians (ASAM) group, an acupoint-selection-at-other-meridians (ASAOM) group and a non-acupoint group, 20 rats in each group. The model of MI was not made in the blank group; the left anterior descending coronary artery was not ligated after thoracotomy in the sham operation group; the model of MI was made but acupuncture was not given in the model group. After the model of MI was made, electroacupuncture (EA) was applied at "Neiguan" (PC 6) in the ASAM group, at "Hegu" (LI 4) in the ASAOM group, and at the area between the third and fourth metatarsal bone in the non-acupoint group. EA was given 20 min per treatment, once a day for 5 days. After treatment, the TTC staining was used to detect myocardial infarction, the Tunel method was used to detect cardiomyocyte apoptosis, and the immunohistochemistry was used to detect the expression of adenosine receptors A1, A2a and A2b. RESULTS: Compared with the blank group and the sham operation group, the percentage of myocardial infarction and apoptotic rate of myocardial cells in the model group were increased significantly (P<0.01). After EA treatment, compared with the model group, the percentage of myocardial infarction and apoptotic rate of myocardial cells in the ASAM group were decreased significantly (P<0.01), and the expression levels of adenosine receptors A1, A2a and A2b were increased significantly (P<0.01). The percentage of myocardial infarction and apoptotic rate of myocardial cells in the ASAM group were significantly lower than those in the ASAOM group and the non-acupoint group (P<0.01), and the expression levels of adenosine receptors A1, A2a and A2b in the ASAM group were significantly higher than those in the ASAOM group and non-acupoint group (P<0.01). CONCLUSION: Compared with acupoint selection at other meridians or non-acupoints, acupoint selection along meridians can effectively regulate the expression of adenosine receptors A1, A2a and A2b, improve the condition of myocardial infarction, inhibit myocardial cell apoptosis, and consequently protect ischemic myocardium.

[Professor LIANG Fan-rong's clinical application of the guiding-qi acupuncture technique].

In clinical practice, professor LIANG Fan-rong integrates the guiding-qi acupuncture technique of slow insertion and withdrawal of the needle with the thought of needling sensation reaching the affected site. These two theories were recorded in Lingshu: Wuluan (Chapter 34 of Miraculous Pivot). Professor Liang proposes that in acupuncture, both acupuncture physician and patient should be in a tranquilizing state. Firstly, the needle is inserted slowly so as to conduct the reversed turbid qi in yang back to yin. After arrival of qi, with the compound manipulation for promoting qi, qi is guided to the affected site. When the treatment ends, the needle is removed slowly to guide the reversed clear qi in yin back to yang and to guide qi of nutrient and defensive systems back to the original layers. Such acupuncture technique is applicable for various disorders induced by the impairment of qi activity. In clinical practice, it is adopted for the disorders of heart, lung, stomach, intestines, emotions and nervous system, as well as the obstruction disorders of meridians. The ying-spring and shu-stream points of the affected meridians are selected as the main acupoints in prescription. According the theory of four seas and qi street, the corresponding the front-mu, back-shu and he-sea points are combined. In acupuncture, the needle is inserted and withdrawn slowly. After arrival of qi, the needle is manipulated to guide qi to the pathogenic locations.

[The sensitization phenomena and regularity of Hegu (LI 4) based on bibliometrics].

The sensitization phenomena and regularities of Hegu (LI 4) were preliminarily explored. The relevant literature regarding Hegu (LI 4) sensitization were collected by computer retrieval at Cochrane Library, Pubmed, Embase (OvidSP), China Journal Full Text Database (CNKI), China Biomedical Literature Database (CBM), VIP and Wanfang (WF) databases as well as manual searching, and a modern literature database of Hegu (LI 4) sensitization was established. The information of disease type, sensitization type, detection method and index were collected. Frequency statistics method was used for analysis. As a result, 47 literatures were included, of which heat sensitivity was the most common type of sensitization, and diseases of liver and gallbladder, limb meridians, lung system, and spleen-stomach system were the most common types of diseases. The detection method of sensitization was various, among them, potassium ion introduction method and hot-water tail-flick method were mainly used for pain sensitivity, while acupoint resistance measuring instrument was mainly used for electric sensitivity, while thermal infrared imager was mainly used for heat sensitivity, while infrared spectrometric analyzer was mainly used for light sensitivity, while pressing pain measuring instrument was used for pressing sensitivity. Detection index was different, pain sensitivity detected pain threshold, electric sensitivity mainly detected acupoint resistance, heat sensitivity mainly detected temperature, light sensitivity detected average sharpness and average energy of infrared radiation, pressing sensitivity detected pressing-pain threshold. In conclusion, the regularities of sensitization of Hegu (LI 4) were preliminarily summarized, which involved five sensitization types: heat sensitivity, electric sensitivity, pain sensitivity, pressing sensitivity and light sensitivity. The sensitization of Hegu (LI 4) was commonly seen in facial paralysis, bronchial asthma, allergic rhinitis, tinnitus, ulcerative colitis. The temperature, pain threshold, pressing-pain threshold, average sharpness and average energy of infrared radiation of Hegu (LI 4) in pathological condition were lower than those in healthy subjects, and the resistance value was higher than that of healthy subjects.

Purines Change at Acupoints along the Pericardium Meridian in Healthy and Myocardial Ischemic Rats.

OBJECTIVE: To quantify the purine concentrations of the acupoints along the pericardium and nonpericardium meridians under healthy and myocardial ischemia conditions to investigate the relationship between acupoint purine change and body functional status in rats. METHODS: A total of 70 rats underwent an operation for myocardial ischemia, while 40 of them survived. They were randomly assigned to the following 5 subgroups: Neiguan (PC 6), Quze (PC 3), Tianquan (PC 2), Quchi (LI 11), and Jianyu (LI 15). Simultaneously, another 40 healthy rats were also randomized into the same 5 subgroups as the control group. The tissue fluids at the acupoints were collected by microdialysis for 30 min. Subsequently, the concentration of adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), and adenosine (ADO) were quantified using the high-performance liquid chromatography method. RESULTS: Compared with the healthy group, the ADO at PC 6 (P=0.012), PC 3 (P=0.038), PC 2 (P=0.024), and LI 15 (P=0.042) obviously increased in the model group, while no significant difference was observed at LI 11 (P=0.201). However, ATP, ADP, and AMP manifested no significant changes in these areas, except for ATP at LI 15 (P=0.036). CONCLUSIONS: Myocardial ischemia could induce an increase in ADO at acupoints of the upper arm and shoulder area, suggesting that the body functional status could affect the responsiveness of acupoints. The status of these acupoints could be pathogenically activated by disease, and distribution following some specific courses.

Acupuncture for hypertension.

BACKGROUND: Elevated blood pressure (hypertension) affects about one billion people worldwide. It is important as it is a major risk factor for stroke and myocardial infarction. However, it remains a challenge for the medical profession as many people with hypertension have blood pressure (BP) that is not well controlled. According to Traditional Chinese Medicine theory, acupuncture has the potential to lower BP. OBJECTIVES: To assess the effectiveness and safety of acupuncture for lowering blood pressure in adults with primary hypertension. SEARCH METHODS: We searched the Hypertension Group Specialised Register (February 2017); the Cochrane Central Register of Controlled Trials (CENTRAL) 2017, Issue 2; MEDLINE (February 2017); Embase (February 2017), China National Knowledge Infrastructure (CNKI) (January 2015), VIP Database (January 2015), the World Health Organisation Clinical Trials Registry Platform (February 2017)and ClinicalTrials.gov (February 2017). There were no language restrictions. SELECTION CRITERIA: We included all randomized controlled trials (RCTs) that compared the clinical effects of an acupuncture intervention (acupuncture used alone or add-on) with no treatment, a sham acupuncture or an antihypertensive drug in adults with primary hypertension. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies according to inclusion and exclusion criteria. They extracted data and assessed the risk of bias of each trial, and telephoned or emailed the authors of the studies to ask for missing information. A third review author resolved disagreements. Outcomes included change in systolic blood pressure (SBP), change in diastolic blood pressure (DBP), withdrawal due to adverse effects, and any adverse events. We calculated pooled mean differences (MD) with 95% confidence intervals (CI) for continuous outcomes using a fixed-effect or random-effects model where appropriate. MAIN RESULTS: Twenty-two RCTs (1744 people) met our inclusion criteria. The RCTs were of variable methodological quality (most at high risk of bias because of lack of blinding). There was no evidence for a sustained BP lowering effect of acupuncture; only one trial investigated a sustained effect and found no BP lowering effect at three and six months after acupuncture. Four sham acupuncture controlled trials provided very low quality evidence that acupuncture had a short-term (one to 24 hours) effect on SBP (change) -3.4 mmHg (-6.0 to -0.9) and DBP -1.9 mmHg (95% CI -3.6 to -0.3). Pooled analysis of eight trials comparing acupuncture with angiotensin-converting enzyme inhibitors and seven trials comparing acupuncture to calcium antagonists suggested that acupuncture lowered short-term BP better than the antihypertensive drugs. However, because of the very high risk of bias in these trials, we think that this is most likely a reflection of bias and not a true effect. As a result, we did not report these results in the 'Summary of findings' table. Safety of acupuncture could not be assessed as only eight trials reported adverse events. AUTHORS' CONCLUSIONS: At present, there is no evidence for the sustained BP lowering effect of acupuncture that is required for the management of chronically elevated BP. The short-term effects of acupuncture are uncertain due to the very low quality of evidence. The larger effect shown in non-sham acupuncture controlled trials most likely reflects bias and is not a true effect. Future RCTs must use sham acupuncture controls and assess whether there is a BP lowering effect of acupuncture that lasts at least seven days.

Surgical and oncological outcomes of an improved nerve-sparing radical hysterectomy technique: 6 years of experience at two centres.

OBJECTIVE: An improved nerve-sparing radical hysterectomy (NSRH), which is based on the paravesico-vaginal space, has been recently introduced in a phase II, prospective clinical trial by our team. This study aims to report the surgical and oncological outcomes of this improved NSRH. METHODS: One hundred seventy-seven consecutive patients were enrolled in our study and underwent the improved NSRH. The proportion of successful catheter removal and postvoid residual urine volume (PVR) of 50 mL or less at postoperative day 7 or day 4 was used to assess surgical outcomes. The local control rate (LCR), disease free survival (DFS), and overall survival (OS) were used to assess oncological outcomes. RESULTS: Postoperative 30-day complications occurred in 27/177 (15.3%) patients. The rate of successful catheter removal and PVR of 50 mL or less were 85.2% (23/27) and 66.7% (18/27) at postoperative day 7, and 73.3% (110/150) and 35.3% (53/150) at postoperative day 4. A total of 13 (7.9%) patients showed recurrence after a median follow-up time of 39.2 months (range 3.2-68.1 months). The estimated 2-year and 5-year DFS rates were 92.2% and 91.1%, respectively. Seven (4.2%) patients presented local recurrence, and five (3.0%) patients were dead at the end of the follow-up period. The estimated 5-year LCR and OS were 95.1% and 96.2%, respectively. In univariate analysis, International Federation of Gynecology and Obstetrics (FIGO) stage, lymphovascular space invasion (LVSI), and lymph node metastasis were found to be the prognostic risk factors of DFS. Patients with LVSI were associated with a worse DFS according to the multivariate analysis. CONCLUSIONS: The improved NSRH in our study may provide better surgical outcomes without compromising the survival in patients with early cervical cancer.

[Development of human embryonic stem cell platforms for human health-safety evaluation].

The human embryonic stem cells (hESCs) serve as a self-renewable, genetically-healthy, pluripotent and single source of all body cells, tissues and organs. Therefore, it is considered as the good standard for all human stem cells by US, Europe and international authorities. In this study, the standard and healthy human mesenchymal progenitors, ligament tissues, cardiomyocytes, keratinocytes, primary neurons, fibroblasts, and salivary serous cells were differentiated from hESCs. The human cellular health-safety of NaF, retinoic acid, 5-fluorouracil, dexamethasone, penicillin G, adriamycin, lead acetate PbAc, bisphenol A-biglycidyl methacrylate (Bis-GMA) were evaluated selectively on the standardized platforms of hESCs, hESCs-derived cardiomyocytes, keratinocytes, primary neurons, and fibroblasts. The evaluations were compared with those on the currently most adopted cellular platforms. Particularly, the sensitivity difference of PM2.5 toxicity on standardized and healthy hESCs derived fibroblasts, currently adopted immortalized human bronchial epithelial cells Beas-2B and human umbilical vein endothelial cells (HUVECs) were evaluated. The RESULTS showed that the standardized hESCs cellular platforms provided more sensitivity and accuracy for human cellular health-safety evaluation.

[Regularities of Acupoint Combinations for Facial Paralysis in Chinese Ancient Times Analyzed in Accordance with Modern Complex Network Community Framework Partition].

OBJECTIVE: To analyze the characteristics of acupoint combinations (formula) for facial palsy in ancient lite-rature, so as to optimize the related acupoint prescriptions in clinical practice. METHODS: The database of ancient acupoint prescriptions for facial paralysis was established first after searching and collecting the related acu-moxibustion literature (178 categories as monographs, specific volumes of a book, etc.) by using key words of "facial palsy" or "deviation of the eye and mouth" including Chinese terms of "Diaoxianfeng ()" "Wopi ()"and "Kouwo()". The characteristics of acupoint selection were analyzed and acupoint prescriptions were optimized using bipartite network community structure partition. RESULTS: The results indicated that of the 56 acupoints for facial palsy collected in the literature, Shuigou (GV 26), Dicang (ST 4), Jiache (ST 6), Hegu(LI 4), Fengchi(GB 20), Zusanli (ST 36), Neiting (ST 44), Tinghui (GB 2), Chengjiang (CV 24) and Shangguan (GB 3) are the core acupoints in clinical application. The acupoints of Dicang (ST 4), Jiache (ST 6), Shuigou (GV 26), Fengchi(GB 20), Neiting (ST 44), Hegu (LI 4), Zusanli (ST 36), Lieque (LU 7), Shangguan (GB 3) and Erjian (LI 2) are most frequently selected for forming prescriptions.The optimized acupoint prescriptions are composed of Tinghui (GB 2), Fengchi (GB 20), Fengshi (GB 31), Xuanzhong (GB 39), Dicang (ST 4), Jiache (ST 6), Zusanli (ST 36), Dazhui (GV 14), Baihui (GV 20), Quchi (LI 11) and Jianyu (LI 15). Core acupoints were mainly distributed on the Stomach Meridian of Foot Yangming, Large Intestine Meridian of Hand Yangming and the Governor Vessel. Acupoints at the face and head are used more frequently than those in any other parts of the body. Specific acupoints are used more frequently than non-specific acupoints, among which Conf-luent Acupoints are most frequently used. CONCLUSIONS: In the treatment of facial paralysis in ancient China, selection of local acupoints is the basic principle and some specific acupoints are the core acupoints in ancient acupuncture prescriptions.

A survey of the practice and perspectives of chinese acupuncturists on deqi.

Deqi refers to the special sensation and reaction sensed mainly by both acupuncturist and patient when a needle was inserted into the acupoints and is considered to be vital to achieve acupuncture effect. For acupuncturist, it is important to judge and control Deqi in clinical practice. However, enough attention is paid to patients' feelings rather than acupuncturists' nowadays. We thus conducted this survey to determine acupuncturists' perspectives about Deqi and to further find the proper way to induce Deqi. A total of 250 questionnaires were sent out to acupuncturists and 202 (80.8%) were returned. According to the results, most acupuncturists believe that Deqi is vital to obtain preferable clinical effects. The reliability of acupuncturists' Deqi sensation ranks as sinking> tightening> astringent. The reliability of patients' Deqi sensations ranks as sourness> numbness> distention> heaviness> pain. The reliability of influential factors ranks as manipulation> specificity of acupoint> TCM constitution> disease status> patient's psychological condition> acupuncturists' psychological guidance> clinical environment. This study is believed to provide additional evidence to the qualitative and quantitative research of Deqi in the future.

[Rules for acupoint selection in treatment of perimenopausal syndrome based on data mining technology].

OBJECTIVE: To analyze the rules for acupoint selection of acupuncture and moxibustion in domestic clinical treatment of perimenopausal syndrome based on data mining technology in modern times. METHODS: The relevant literature were retrieved from Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI) and Wanfang database on this disease treated with clinical acupuncture and moxibustion in China from 1978 to 2013. The database of acupuncture-moxibustion prescription was set up. The relevant regulations of data mining technology were used to analyze the rules for acupoint selection. RESULTS: Totally, 211 papers, 254 acupuncture-moxibustion prescriptions and 130 acupoints were included. The total frequency of acupoints application was 2193 times, with 14 meridians involved. The utilization of the acupoints in the lower limbs and on the back were 33.0% (723/2193) and 23.8% (521/2193) and those of yin and yang meridians were 51.8% (1136/2193) and 44.0% (965/2193), respectively. The utilization of the specific acupoints accounted for 88.7% (1946/2193). CONCLUSION: In clinical treatment of perimenopausal syndrome with acupuncture and moxibustion in modern times, the acupoint selection from involved meridians is the basis, associated with multiple methods of acupoint combination; yin and yang meridians are equally important and the specific acupoints are considered particularly critical in application.

[Problems and solutions on transformation of scientific research achievements of acupuncture].

With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.

[Discussion on disease spectrum treated with acupuncture at shenmen (HT 7) and its compatibility based on bibliometrics].

The modern literatures on the diseases treated with acupuncture at Shenmen (HT 7) were collected. Using literature statistical analysis in bibliometrics, the common compatibility of Shenmen (HT 7) and the disease spectrum were analyzed so as to provide the references of the diseases that can be treated with acupuncture at Shenmen (HT 7). It was found that 39 kinds of diseases and symptoms, mainly nerve system disedses, could be treated with acupuncture at Shenmen (HT 7), including insomnia, depression, anxiety and dementia. Shenmen (HT 7) was seldom used alone. Instead, it was commonly used along with Baihui (GV 20), Sanyinjiao (SP 6), Neiguan (PC 6), Sishencong (EX-HN 1) and Taicong (LR 3).
