Objective:To observe the effect of intradermal needle therapy on back-shu points of five zang organs in treating chronic fatigue syndrome(CFS)and provide evidence for the usage of unilateral back-shu point.Methods:Patients were randomly divided into bilateral back-shu point group,unilateral back-shu point group and non-acupoint group,remove shedding cases,each group remaining 30 patients.In bilateral back-shu point group,both sides of back-shu points of five zang organs were selected.In unilateral back-shu point group,only one side was selected,left or right alternately.The location where non-acupoint group inserted by intradermal needles were outward from the back-shu points,left or right alternately.Fatigue Scale-14(FS-14)was used to evaluate the fatigue level and the scores’improvement of physical fatigue and mental fatigue revealed the therapeutic effect on body constituents and spirits of CFS patient.Results:After the 8-week intradermal needle therapy,the total effective rate was 83.33%in the bilateral back-shu point group,which was 76.67%in the unilateral back-shu point group and 50.00%in the non-acupoint group.The curative effects of the two groups whose back-shu points of five zang organs were inserted by intradermal needles were better than the non-acupoint group(P<0.05).There was no significant difference in clinical efficacy between the bilateral back-shu point group and the unilateral back-shu point group(P>0.05).There were statistical differences in FS-14 questionnaires including total,physical and mental scores between before and after the treatment in both the two back-shu point groups(P<0.05).Only the scores of total and physical fatigue in decreased in non-acupoint group(P<0.05),which means it couldn’t help to alleviate mental fatigue statistically(P>0.05).Conclusions:(1)The intradermal needle therapy on back-shu points of five zang organs for CFS has a satisfying clinical efficacy in curing tiredness.It can help to reduce both physical and mental fatigue for the patients.Hence,it can regulate both body constituents and spirits simultaneously.(2)Needling the unilateral acupoints can get similar clinical efficacy to the bilateral points.It reveals that we can cut cost by reducing the consumption of the amount of intradermal needles used on one side.(3)Both the groups of back-shu points get better clinical efficacy than the non-acupoint group dramatically.The reason of why the intradermal needle can treat CFS maybe that back-shu points of five zang organs can regulate the functions of five zang organs characteristically. 展开更多

To observe the clinical effect of treatment of acute bronchitis primarily with prickingcupping method on Back-shu points. Methods. The patients of acute bronchitis were randomly divided into 2 groups. In the observation group, there were 36 cases, who were treated with the integrated traditional Chinese and western medicine, primarily the pricking-cupping method on Back-shu points; while in the control group, there were 29 cases who were given the conventinal treatment of western medicine. All the 2 groups were treated for 7 days as one treating course. Results: The total effective rate of the observation group was 97.2% while that of the control group was 82,8%, so there is a significant difference between them. On the first and third days the clinical manifestations were more satisfactorily improved in the treatment group than in the control group (P 〈 0.01) and on the fifth and seventh days, the comparison showed no significant difference (P〉0.05). Conclusion: The treatment of acute bronchitis by means of the integrated traditional Chinese and western medicine primarily with pricking-cupping method on Back-shu points is of marked therapeutic effect, simple manipulation, and little untoward effects, thus claiming the unique advantage. 展开更多

Urticaria is a common and frequently encountered disease, which is mainly manifested by extreme pruritus and lumpish eruption of the skin. Acute urticaria with a short disease course can be cured, while the chronic one with repeated attacks is a lingering disorder. In the past few years, 40 cases of urticaria were treated by cupping at the back-shu points of the five zang-organs and Geshu (BL 17). Another 20 cases in the control group were treated with Fang Feng Tong Sheng Wan (防风通圣丸Miraculous Pills of Ledebouriella) and chlorpheniramine maleate. The therapeutic effect in the treatment group was significantly superior to that in the control group. The results are reported as follows. 展开更多

Using angle-resolved photoemission spectroscopy and density functional theory calculations methods,we investigate the electronic structures and topological properties of ternary tellurides NbIrTe_(4),a candidate for type-II Weyl semimetal.We demonstrate the presence of several Fermi arcs connecting their corresponding Weyl points on both termination surfaces of the topological material.Our analysis reveals the existence of Dirac points,in addition to Weyl points,giving both theoretical and experimental evidences of the coexistence of Dirac and Weyl points in a single material.These findings not only confirm NbIrTe_(4) as a unique topological semimetal but also open avenues for exploring novel electronic devices based on its coexisting Dirac and Weyl fermions. 展开更多

We study the exceptional-point(EP) structure and the associated quantum dynamics in a system consisting of a non-Hermitian qubit and a Hermitian qubit. We find that the system possesses two sets of EPs, which divide the systemparameter space into PT-symmetry unbroken, partially broken and fully broken regimes, each with distinct quantumdynamics characteristics. Particularly, in the partially broken regime, while the PT-symmetry is generally broken in the whole four-dimensional Hilbert space, it is preserved in a two-dimensional subspace such that the quantum dynamics in the subspace are similar to those in the PT-symmetry unbroken regime. In addition, we reveal that the competition between the inter-qubit coupling and the intra-qubit driving gives rise to a complex pattern in the EP variation with system parameters. 展开更多

Ecosystems generally have the self-adapting ability to resist various external pressures or disturbances,which is always called resilience.However,once the external disturbances exceed the tipping points of the system resilience,the consequences would be catastrophic,and eventually lead the ecosystem to complete collapse.We capture the collapse process of ecosystems represented by plant-pollinator networks with the k-core nested structural method,and find that a sufficiently weak interaction strength or a sufficiently large competition weight can cause the structure of the ecosystem to collapse from its smallest k-core towards its largest k-core.Then we give the tipping points of structure and dynamic collapse of the entire system from the one-dimensional dynamic function of the ecosystem.Our work provides an intuitive and precise description of the dynamic process of ecosystem collapse under multiple interactions,and provides theoretical insights into further avoiding the occurrence of ecosystem collapse. 展开更多

By considering the negative cosmological constant Λ as a thermodynamic pressure, we study the thermodynamics and phase transitions of the D-dimensional dyonic Ad S black holes(BHs) with quasitopological electromagnetism in Einstein–Gauss–Bonnet(EGB) gravity. The results indicate that the small/large BH phase transition that is similar to the van der Waals(vdW) liquid/gas phase transition always exists for any spacetime dimensions. Interestingly, we then find that this BH system exhibits a more complex phase structure in 6-dimensional case that is missed in other dimensions.Specifically, it shows for D = 6 that we observed the small/intermediate/large BH phase transitions in a specific parameter region with the triple point naturally appeared. Moreover, when the magnetic charge turned off, we still observed the small/intermediate/large BH phase transitions and triple point only in 6-dimensional spacetime, which is consistent with the previous results. However, for the dyonic Ad S BHs with quasitopological electromagnetism in Einstein–Born–Infeld(EBI) gravity, the novel phase structure composed of two separate coexistence curves observed by Li et al. [Phys. Rev. D105 104048(2022)] disappeared in EGB gravity. This implies that this novel phase structure is closely related to gravity theories, and seems to have nothing to do with the effect of quasitopological electromagnetism. In addition, it is also true that the critical exponents calculated near the critical points possess identical values as mean field theory. Finally, we conclude that these findings shall provide some deep insights into the intriguing thermodynamic properties of the dyonic Ad S BHs with quasitopological electromagnetism in EGB gravity. 展开更多

The findings of a study to ascertain and assess the petrophysical characteristics of Cape Three Points reservoirs in the Western basin with a view to describe the reservoir quantitatively using Well Logs, Petrel and Techlog. The investigated characteristics, which were all deduced from geophysical wire-line logs, include lithology, porosity, permeability, fluid saturation, and net to gross thickness. To characterise the reservoir on the field, a suite of wire-line logs including gamma ray, resistivity, spontaneous potential, and density logs for three wells (WELL_1X, WELL_2X, and WELL_3X) from the Tano Cape Three Point basin were studied. The analyses that were done included lithology delineation, reservoir identification, and petrophysical parameter determination for the identified reservoirs. The tops and bases of the three wells analysed were marked at a depth of 1203.06 - 2015.64 m, 3863.03 - 4253.85 m and 2497.38 - 2560.32 m respectively. There were no hydrocarbons in the reservoirs from the studies. The petrophysical parameters computed for each reservoir provided porosities of 13%, 3% and 11% respectively. The water saturation also determined for these three wells (WELL_1X, WELL_2X and WELL_3X) were 94%, 95% and 89% respectively. These results together with the behaviour of the density and neutron logs suggested that these wells are wildcat wells. 展开更多

Mottness is at the heart of the essential physics in a strongly correlated system as many novel quantum phenomena occur in the metallic phase near the Mott metal–insulator transition. We investigate the Mott transition in a Hubbard model by using the dynamical mean-field theory and introduce the local quantum state fidelity to depict the Mott metal–insulator transition. The local quantum state fidelity provides a convenient approach to determining the critical point of the Mott transition. Additionally, it presents a consistent description of the two distinct forms of the Mott transition points. 展开更多

The inflection point is an important feature of sigmoidal height-diameter(H-D)models.It is often cited as one of the properties favoring sigmoidal model forms.However,there are very few studies analyzing the inflection points of H-D models.The goals of this study were to theoretically and empirically examine the behaviors of inflection points of six common H-D models with a regional dataset.The six models were the Wykoff(WYK),Schumacher(SCH),Curtis(CUR),HossfeldⅣ(HOS),von Bertalanffy-Richards(VBR),and Gompertz(GPZ)models.The models were first fitted in their base forms with tree species as random effects and were then expanded to include functional traits and spatial distribution.The distributions of the estimated inflection points were similar between the two-parameter models WYK,SCH,and CUR,but were different between the threeparameter models HOS,VBR,and GPZ.GPZ produced some of the largest inflection points.HOS and VBR produced concave H-D curves without inflection points for 12.7%and 39.7%of the tree species.Evergreen species or decreasing shade tolerance resulted in larger inflection points.The trends in the estimated inflection points of HOS and VBR were entirely opposite across the landscape.Furthermore,HOS could produce concave H-D curves for portions of the landscape.Based on the studied behaviors,the choice between two-parameter models may not matter.We recommend comparing seve ral three-parameter model forms for consistency in estimated inflection points before deciding on one.Believing sigmoidal models to have inflection points does not necessarily mean that they will produce fitted curves with one.Our study highlights the need to integrate analysis of inflection points into modeling H-D relationships. 展开更多

Objective To observe the clinical therapeutic effect on insomnia treated with acupuncture at back-shu points. Methods Sixty-four cases of insomnia were selected and divided randomly into a back-shu points group (group A) and a conventional acupoints group (group B) by a computer generated allocation list, 32 cases in each one. In the trial group, acupuncture was applied at xinshu (心俞 15), Ganshu (刊俞 18), Pishu (脾俞 BL 20) and Geshu (膈俞 BL 17). In the control group, acupuncture was applied conventionally to Neiguan (内关 PC 6), Shenmen (神门 HT 7), Sanyinjiao (三阴交 SP 6), Baihui (百会 GV 20) and Sishencong (四神聪 EX-HN 2). Ten treatments made a session. The efficacy was analyzed statistically after 3 sessions of treatment. Results There were significant differences between the two groups in the relief of sleep disorders after the treatment (P〈0.O2). The improvement in sleep efficiency was different significantly (P〈0.05). The difference in sleep difficulty was significant in Chinese medicine (TCM) symptom score (P〈0.05). Conclusion The clinical efficacy is achieved by either acupuncture at back-shu points or by acupuncture at conventional acupoints. The improvements of sleep efficiency and sleep disorder scores in PSO.I, and sleep difficulty in TCM as well as the long-term efficacy are superior in group A as compared with those in group B. 展开更多

Objective: To observe the clinical efficacy of acupuncture on back-shu points of five zang in treating chronic fatigue syndrome(CFS).Methods: Sixty patients were randomized into treatment group and control group. In treatment group,the back-shu points of five zang organs were adopted for acupuncture. Shènshū(肾俞 BL23) was perpendicularly needled 15-30 mm in depth. The rest of the selected points were inserted obliquely 15-30 mm in the direction of the spine with even method of lifting-thrusting and twisting-twirling, 10 s for each acupoint. In control group, the acupoints were approximately 1.5-2 cm away outward from the back-shu points of five zang organs(about on the middle of the two sidelines of the bladder meridian of foottaiyang) and the points from the bladder meridian of foot-taiyang were excluded. Acupoints were needled6-9 mm in depth, and deqi was not required, without any manipulation. The treatments were carried out twice a week for twenty minutes each time, a total of eight treatments were given. The clinical efficacy of acupuncture treatment for CFS was evaluated through the Fatigue Scale-14(FS-14) and the Symptom Check-List 90(SCL-90) after treatment.Results: The total effective rate was 86.67% in the treatment group and 53.33% in the control group(P<0.01). In treatment group, FS-14 total scores, somatic fatigue scores, and mental fatigue scores were significantly reduced than before treatment(all P<0.01). In control group, FS-14 total scores and somatic fatigue scores were significantly reduced(both P<0.01). The improvement of FS-14 total scores, somatic fatigue scores, and mental fatigue scores in the treatment group were better than those in the control group(P<0.01, P<0.05). After treatment, SCL-90 total scores and somatization, compulsion, interpersonal sensitivity, depression, anxiety, hostility, psychoticism, and other factors scores were significantly reduced in the treatment group compared with before treatment(P<0.01). In control group, the SCL-90 total scores and the scores of somatization, compulsion, hostility, and other factors after treatment were lower than those before treatment(P< 0.01). The total scores of SCL-90 and somatization, compulsion, interpersonal sensitivity, depression, anxiety, psychoticism, and other factors in the treatment group were significantly lower than those in the control group(P< 0.01, P< 0.05).Conclusions: Acupuncture on back-shu points of five zang can significantly improve the somatic fatigue and mental fatigue of the patients, and at the same time improve their psychological status. Significant therapeutic effect was found on CFS. Compared with the control group, the acupuncture treatment can significantly improve the patient’s somatic fatigue, mental fatigue and psychological status. 展开更多

Exploring the effects of sowing date and ecological points on the yield of semi-winter wheat is of great significance.This study aims to reveal the effects of sowing date and ecological points on the climate resources associated with wheat yield in the Rice–Wheat Rotation System.With six sowing dates,the experiments were carried out in Donghai and Jianhu counties,Jiangsu Province,China using two semi-winter wheat varieties as the objects of this study.The basic seedlings of the first sowing date (S1) were planted at 300×10^(4)plants ha^(-1),which was increased by 10%for each of the delayed sowing dates (S2–S6).The results showed that the delay of sowing date decreased the number of days,the effective accumulated temperature and the cumulative solar radiation in the whole growth period.The yields of S1 were higher than those of S2 to S6 by 0.22–0.31,0.5–0.78,0.86–0.98,1.14–1.38,and 1.36–1.59 t ha^(–1),respectively.For a given sowing date,the growth days increased as the ecological point was moved north,while both mean daily temperature and effective accumulative temperature decreased,but the cumulative radiation increased.As a result,the yields at Donghai County were 0.01–0.39 t ha–1lower than those of Jianhu County for the six sowing dates.The effective accumulative temperature and cumulative radiation both had significant positive correlations with yield.The average temperature was significantly negatively correlated with the yield.The decrease in grain yield was mainly due to the declines in grains per spike and 1 000-grain weight caused by the increase in the daily temperature and the decrease in the effective accumulative temperature. 展开更多

Methods: Twenty-two subjects were recruited and treated by puncturing corresponding Back-Shu points based on syndrome differentiation. The short-form General Health Survey (MOSSF GHS) and the Chalder Questionnaires for Fatigue were adopted for evaluating the therapeutic effects. Results: Of the 22 patients, 4 cases showed a marked effect, 11 got effect, 7 got failure, and the total effective rate was 68.2%. Conclusion: Puncturing Back-Shu points is effective in relieving the symptoms of chronic fatigue syndrome and enhancing the patients' health standard. 展开更多
