It comprises five subunits: melange belt, foreland deformation belt, molasse and littoral basin, arc diorite series and syn-collision granitoid series. Evolution history of the orogenic belt can be divided into subduction stage (500-400 Ma) and collision stage (400-320 Ma). The formation of the orogenic belt caused the convergence between the Siberian and North China Plates during the late Devonian. Suture zone corresponding to the melange belt extends from Erdao-jing, Qagan Ura to Honggor.展开更多

Acupuncture and moxibustion (acu-moxi) is beneficial in treating facial palsy. In order to verify the efficacy of acu-moxi on Bell’s palsy, a randomized single-blind, multicenter clinical trial was performed.Methods A total of 480 patients from four clinical centers were involved in this trial, of whom 439 completed the trial and 41 did not. All patients were randomly assigned to either the control group or to one of two treatment groups. The control group was treated with prednisone, vitamin B_1, vitamin B_ 12, and dibazole; the treatment groups were treated either with acu-moxi alone or in combination with prednisone, Vitamin B_1, vitamin B_ 12, and dibazole. Symptoms and signs, the House-Brackmann scale, and facial disability index (FDI) scores were assessed and determined both pre- and post-treatment to evaluate the effectiveness of the treatment methods.Results The characteristics of the control and two treatment groups were comparable without statistically significant differences before treatment. There were significant differences between the control and treatment groups after treatment (χ2=15.265, P=0.018). According to evaluations based on the House-Brackmann scale and FDI scores, the effectiveness of treatment in the two treatment groups was better than in the control group and was most effective in patients receiving acu-moxi treatment alone (Z=-2.827, P=0.005). Conclusion The efficacy of acu-moxi treatment for Bell’s palsy is verified scientifically.展开更多

Green bell peppers were collected in bags and treated with 0, 5, 10, 20, and 50 mg L^-1 ClO2 gas at 10±0.5℃ for over 40 d, and the changes in postharvest physiology and preservation quality of the peppers were evaluated during the storage. The inhibition of rot of the peppers was observed for all the tested ClO2 gas treatments. The rot rates of the treated samples were 50% lesser than those of the control after day 40 of storage. The highest inhibitory effect was obtained after 50 mg L^-1 ClO2 gas treatment, where the peppers did not decay until day 30 and showed only one-fourth of the rot rate of the control at day 40 of storage. The respiratory activity of the peppers was significantly （P〈0.05） inhibited by 20 and 50 mg L^-1 ClO2 treatments, whereas no significant effects on respiratory activity were observed with 5 and 10 mg L^-1 ClO2 treatments （P〉0.05）. Except for 50 mg L^-1 ClO2, malondialdenyde （MDA） contents in the peppers treated with 5, 10, or 20 mg L^-1 ClO2 were not significantly （P〉0.05） different from those in the control. Degradation of chlorophyll in the peppers was delayed by 5 mg L-1ClO2, but promoted by 10, 20, or 50 mg L^-1 ClO2. The vitamin C content, titratable acidity, and total soluble solids of the peppers treated by all the tested ClO2 gas did not significantly change during the storage. The results suggested that ClO2 gas treatment effectively delayed the postharvest physiological transformation of green peppers, inhibited decay and respiration, maintained some nutritional and sensory quality, and retarded MDA accumulation.展开更多

Here, we report the first long-distance QSDC experiment, including the security test, information encoding, fiber transmission and decoding. After the fiber transmission of 0.5 km, quantum state fidelities of the two polarization entangled Bell states are 91% and 88%, respectively, which are used for information coding. We theoretically analyze the performance of the QSDC system based on current optical communication technologies,showing that QSDC over fiber links of several tens kilometers could be expected. It demonstrates the potential of long-distance QSDC and supports its future applications on quantum communication networks.展开更多

A server on the network, say Alice, provides the service for preparing and measuring single photons whose initial state are ｜0〉. The users code the information on the single photons with some unitary operations. To prevent the untrustworthy server Alice from eavesdropping the quantum lines, a nonorthogonal-coding technique is used in the process that the quantum signal is transmitted between the users. This protocol does not require the servers and the users to store the quantum states and almost all of the single photons can be used for carrying the information, which makes it more convenient for application than others with present technology. We also discuss the case with a faint laser pulse.展开更多

The server, say Alice, prepares and measures the EPR pairs in the quantum communication and the users perform the four local unitary operations to encode their message. Anyone of the legitimate users can communicate another one on the network securely. Since almost all of the instances in this scheme are useful and each EPR pair can carry two bits of information, the efficiency for qubits and the source capacity both approach the maximal values.展开更多

For an arbitrary m-qudit state, the sender Alice performs m generalized Bell-state projective measurements on her 2m qudits and the controllers need only take some single-particle measurements. The receiver Charlie can reconstruct the unknown m-qudit state by performing some single-qudit unitary operations on her particles if she cooperates with all the controllers. As the quantum channel is a sequence of maximally entangled GHZ states, the intrinsic efticiency for qudits in this scheme approaches 100% in principle.展开更多

In the scheme, three spatially separated senders, Alice, Bob and Charlie, transmit their secret messages to a remote receiver Diana by performing a series of local operations on their respective particles according to the quadripartite stipulation. From Alice, Bob, Charlie and Diana＇s Bell measurement results, Diana can infer the secret messages. Ira perfect quantum channel is used, the secret messages are faithfully transmitted from Alice, Bob and Charlie to Diana via initially shared pairs of four-particle GHZ states without revealing any information to a potential eavesdropper. As there is no transmission of the qubits carrying the secret message in the public channel, it is completely secure for the direct secret communication. This scheme can be considered as a network of communication parties where each party wants to communicate secretly with a central party or server.展开更多

Effects of personality factors on the therapeutic effect of acupuncture have not been investigated. This study aimed to find the effects of the traits of personality on the objective outcome when different acupuncture techniques were used in treating patients with Bell＇s palsy. Methods： We performed a secondary analysis of a prospective multicenter randomized controlled trial of acupuncture for Bell＇s palsy. Patients were randomly assigned to the de qi and control groups, respectively. The primary outcome was facial nerve function at month 6. The intensity of each needle sensation was rated by a visual analog scale. Psychosocial thctors were assessed by the pretreatment mediator questionnaire： 16 Personality Factor Questionnaire （16PF） was used tbr assessing personality factors and digit cancellation test for assessing attention. Results： After 6 months, patients in the de qi group had better facial function （adjusted odds ratio [OR]： 4.16, 95% confidence interval [CI]： 2.23-7.78）. Path analysis showed that intensity of needle sensation of fullness had direct effect on House-Brackmann （HB） score at month 6. In de qi group, the low HB score on day I （OR： 0.13, 95% （_7： 0.03-0.45） and the low Social Boldness score （OR： 0.63, 95% CI： 0.41-0.97） in 16PF were associated with better facial function. In control group, low HB score on day 1 （OR： 0.25, 95% CI： 0.13-0.50）, low Vigilance score （OR： 0.66, 95% CI： 0.50-0.88）, and high Tension score （OR： 1.41,95% CI： 1.12 1.77） in 16PF were related to better facial function. Conclusions： The needle sensation of fullness could predict better facial function and personality traits might influence outcomes of acupuncture treatment. Both of them should be considered seriously in acupuncture treatment and research.展开更多

B...Subjects with Bell＇s palsy and healthy individuals were treated with moxibustion thermal stimulation on the Hegu （LI4） acupoint; an infrared thermal imaging system was used to observe facial-temperature changes. Bell＇s palsy patients developed low or high temperatures at the affected side, with poor symmetry. Healthy people showed high temperatures on the forehead, medial angle of the eye, nasal ala and around the lips, but low temperatures on bilateral cheeks, thus forming a ＂T-type hot area＂ in the face, with good temperature symmetry. Moxibustion treatment for 11 minutes significantly improved high asymmetry in temperature in the faces of Bell＇s palsy patients. This evidence indicates that moxibustion treatment on Hegu enables increases in facial temperatures in healthy people and Bell＇s palsy patients, especially around the lips. Moxibustion stimulation at the Hegu not only improves the global circulation but also has specific effects on the lips in Bell＇s palsy patients, but the underlying mechanism needs further investigation.展开更多

Our previous studies found that observing the electrical response of specific facial muscles provided reasonable correlation with the prognosis of electroacupuncture treatment. Hence, we used the new method to evaluate the degree of facial nerve injury in patients with Bell＇s palsy in comparison with the House-Brackmann scale. The relationship between therapeutic effects and prognosis was analyzed to explore an objective method for evaluating Bell＇s palsy. METHODS： The facial nerve function of 68 patients with Bell＇s palsy was assessed with both electrical response grading and the House-Brackmann scale before treatment. Then differences in evaluation results of the two methods were compared. All enrolled patients received electroacupuncture treatment with disperse-dense wave at 1/100 Hz for 4 weeks. After treatment, correlation analysis was conducted to find the relationship between electrical response and therapeutic effects or prognosis. RESULTS： Checking consistency between electrical response grading and House-Brackmann scale： Kappa value 0.028 （P = 0.578）. Correlation analysis： the two methods were correlated with the prognosis, and electrical response grading （rER = 0.789） was better than the House-Brackmann scale （rHB = 0.423）. CONCLUSION： Electrical response grading is superior to the House-Brackmann scale in efficacy and reliability, and can conveniently assess the degree of facial nerve injury. The House-Brackmann scale is suitable for the patients with mild facial nerve injury, but its evaluation quality for severe facial nerve injury is poor.展开更多

Methods： Thirty patients with acute facial paralysis were enrolled and acupunctured in facial points and bilateral Hegu （LI 14）, and the PeriCam laser speckle flow video monitoring system was used not only for recording ocular skin blood perfusion condition in both normal and affected sides before acupuncture, at 15 min after acupuncture and after removing needles immediately, but also for calculating reduction ratio of ocular skin average perfusion in the affected side face compared with the healthy side. Results： Compared with the healthy side of face, the ocular skin blood perfusion of the affected side after acupuncture was significantly different from that before intervention. The blood perfusion levels after 1S-minute acupuncture and at the time of remaining needles were significantly different from the basic line （all P〈0.01）. Conclusion： Acupuncture can significantly improve eve blood perfusion of the acute facial paralysis, enhance metabolic activity of the affected facial tissues, and promote the recovery of facial nerve function.展开更多
