Objective To analyze the bibliometry of the literature of acupoint thread-embedding in treating simple obesity, and to provide references for clinic.Method By both computer and manual retrieval, the relevant literatures over the past 30 years were collected from the Chinese Journal Full-text Database (CJFD), Vip database, WanFang database. By using the SPSS 17.0 software for statistical analysis, the distribution (province or city), publication year, and journal of the literatures, supporting fund, sample size, research method, material of the thread, use frequency of the involved acupoints, and the meridians of the selected acupoints were summarized.Result The included eligible 175 articles were distributed over many provinces and cities; the publication amount had been increasing year by year; there was a variety of thread materials; the literature with supporting funds only occupied a small percentage, while the research with a small sample size occupied a comparatively large percentage, and the randomized controlled trials (RCTs) also had a small percentage.Conclusion As a common Chinese external therapy in treating simple obesity, acupoint thread-embedding has been paid more and more attention for its practical value and bright future. However, the relevant governmental department hasn’t paid enough attention to this therapy, and the low clinical research quality also makes it difficult to scientifically evaluate its clinical efficacy and safety. Therefore, more attention is required, RCTs of multicenter and large sample size are expected, and clinical research quality also needs improvement, to provide references for clinic.

The relationship between acupuncture and stress is discussed from three aspects, including is it possible for acupuncture stimulation to be a stressor, whether acupuncture will start stress reaction, and whether acupuncture effects contain some stress factors. It is believed that correct acupuncture manipulation will not cause stress response, however, under some circumstances, such as inaccurate manipulation, improper treatment or patients who are very nervous but do not receive effective intervention, acupuncture is likely to cause stress response. Acupuncture-induced stress response is totally different from acupuncture anti-stress. The possible stress factors in acupuncture effect are explored, which can provide a new angle for the research on action mechanism of acupuncture. From the view of stress to review acupuncture treatment, there are three enlightenments: emphasizing on communication between doctors and patients, avoiding over-pursuit of deqi and focusing on analysis of the body constitution.

As a kind of Chinese materia medica (CMM), it contains complex chemical composition and has these pharmacological effects: to remove toxic heat, wake up the brain orifices, eliminate the mass, step-down blood pressure, increase myocardial contraction force and coronary artery blood flow, and use for antitumor and anesthesia. It is widely used in diseases in clinic such as cardiovascular, respiratory, facial features, and surgical treatment. While, as toxic CMM, the concentration-response relationship, toxic ingredients, toxic dose, and poisoning mechanism should not be ignored also. The author preliminarily summaries its effects from composition, pharmacological effects and mechanisms, adverse reactions, processing technology, and pharmacokinetics, and provides the references for its further pharmacological study and compound preparation development.

The study aims to develop a unified method to determine seven phenolic acids (neochlorogenic acid, chlorogenic acid, 4-caffeoylquinic acid, caffeic acid, isochlorogenic acid B, isochlorogenic acid A and isochlorogenic acid C) contained in honeysuckle flower that is the monarch drug of all the eight Yinqiao Jiedu serial preparations using quantitative analysis of multi-components by single-marker (QAMS). Firstly, chlorogenic acid was used as a reference to get the average relative correction factors (RCFs) of the other phenolic acids in ratios to the reference; columns and instruments from different companies were used to validate the durability of the achieved RCFs in different levels of standard solutions; and honeysuckle flower extract was used as the reference substance to fix the positions of chromatographic peaks. Secondly, the contents of seven phenolic acids in eight different Yinqiao Jiedu serial preparations samples were calculated based on the RCFs durability. Finally, the quantitative results were compared between QAMS and the external standard (ES) method. The results have showed that the durability of the achieved RCFs is good (RSD during 0.80% - 2.56%), and there are no differences between the quantitative results of QAMS and ES (the relative average deviation < 0.93%). So it can be successfully used to the quantitative control of honeysuckle flower principally prescribed in Yinqiao Jiedu serial preparations.

OBJECTIVETo explore the action mechanism of electroacupuncture (EA) at "Shenmen" (HT 7) and "Sanyinjiao" (SP 6) on insomnia.

METHODSThirty SD rats were randomly divided into a blank group, a model group and an EA group, 10 cases in each group. The insomnia model was made by immobilization method in the model group and EA group. After model establishment, rats in the blank group and model group were treated with fixation and no treatment was given. Rats in the EA group were treated with EA at "Shenmen" (HT 7) and "San-yinjiao" (SP 6) for 15 min, once a day for 4 days. After treatment, the level of daytime and nighttime activity, open-arm entry percentage and open-arm time percentage of elevated plus-maze test were measured; the content of noradrenaline (NE), dopamine (DA) and epinephrine (EPI) in plasma and NE, DA in thalamus and brainstem were detected by using euzymelinked immunosorbent assay method.

RESULTSCompared with the blank group, the daytime activity was increased and nighttime activity was reduced in the model group (both P<0. 05); the open-arm entry percentage and open-arm time percentage of elevated plus-maze test were both reduced in the model group (both P<0. 05); the contents of NE, DA, EPI in the plasma and NE, DA in thalamus and brainstem were increased in the model group (all P<0. 05). Compared with the model group, the daytime activity was reduced and nighttime activity was increased in the EA group (both P<0. 05); the open-arm entry percentage and open-arm time percentage of elevated plus-maze test were both increased in the EA group (both P<0. 05); the contents of NE, DA, EPI in the plasma and NE, DA in thalamus and brainstem were reduced in the EA group (all P< 0. 05).

CONCLUSIONElectroacupuncture at "Shenmen" (HT 7) and "Sanyinjiao" (SP 6) can restrain the over-activity of the sympathetic-adrenal medullary system to treat the insomnia.

Objective To observe the effects of early rehabilitation on the serum neuron specific enolase (NSE) levels of patients with acute cerebral infarction.MethodsSixty patients with acute cerebral infarction were randomly divided into a rehabilitation group and a control group. All received routine treatment at the acute stage, including anti-platelet aggregation medication, drugs for improving microcirculation, neurotrophic agents and prompt treatment of any complications. Patients in the rehabilitation group also received systemic rehabilitation training beginning immediately after their vital signs had been stabilized. NSE in serum was assayed before treatment and after 3, 7and 14 days. National Institutes of Health stroke scale (NIHSS) scores were evaluated at each time point, and the two groups were compared.ResultsThere was no significant difference in serum NSE or NIHSS scores between the two groups pre-treatment. Both groups improved to a certain extent, but the improvements in the rehabilitation group were significantly better than in the control group, as their NSE levels at 7 days and NIHSS scores at 14 days were both significantly better.ConclusionsEarly rehabilitation intervention contributes to reducing serum NSE levels after acute cerebral infarction, lessening brain injury, and thereby promoting the recovery of damaged neural function.That may be one of the mechanisms by which early rehabilitation promotes functional recovery in patients with acute cerebral infarction.

Introduction: Our aim was to examine the changes in the self-rated frequency of activities among elderly residents living in communities during the self-restraint period associated with the Coronavirus Disease 2019 (COVID-19) pandemic.Methods: Regular outpatients aged 75 years or older who visited the hospital or clinic at the Center for Community Medicine in north-western Gifu prefecture between May 11 and May 22, 2020 were selected as participants. The frequency of outings, walks, outdoor exercise, indoor exercise, farm work, communication and interaction, such as at community salons, direct communication with friends and estranged family members, and remote communication by telephone and video calls was surveyed using a questionnaire method at four levels: "0 days", "1-2 days", "3-4 days", and "5 days to every day" per week in the two weeks prior to the visit and in the same period in the previous year.Results: In total, 292 people aged 75-95 years participated in the study. There was an increase in the number of respondents who reported a lower frequency of going out, walking, farming, outdoor exercise, home exercise, visiting community salons, and direct conversation than in the previous year. There was a significant difference between the two groups (P<0.05).Conclusion: In this study, the self-rated frequency of physical activity and social activity decreased among community-dwelling elderly due to the COVID-19 epidemic, suggesting a reduction in these activities.
