Methods: from May 2019 to May 2020, 88 patients with non-stomach deficiency and stomachache in our hospital were selected, and all of them were divided by drawing lot as the observation group (44 cases, acupuncture treatment) and the control group (44 cases, acupuncture treatment alone). The total effective rate and quality of life score of the two groups were observed. Results: there was no significant difference in quality of life score between the two groups before treatment, but there was significant difference in total effective rate and quality of life score between the two groups after treatment (P < 0.05). Conclusion: acupuncture combined with moxibustion can achieve high therapeutic effect for patients with epigastric pain of spleen stomach deficiency cold type, effectively alleviate patients' clinical symptoms and improve patients' quality of life score, which can be vigorously promoted in clinical experiments.展开更多

After intervening for 3 menstrual cycles,visual analogue scale and the COX menstrual symptom scale were used to evaluate the clinical efficacy of graphene waist protector. [Results] The clinical effective rate of dysmenorrhea in experimental group was 64. 00%,while that of control group was 72. 54%. With the effective rate of symptoms,the test group was 56. 00% and the control group was 64. 70%; VAS dysmenorrhea visual score,duration of dysmenorrhea,severity of COX dysmenorrhea and duration of symptoms after intervention were significantly decreased in both experimental group and control group,the differences were statistically significant( P < 0. 05); for the differences of the scores before and after the intervention: the differences of the experimental group and the control group were statistically significant( P < 0. 05) compared with those of the blank group. There was no significant difference between experimental group and control group( P > 0. 05). [Conclusions] Graphene belt of experimental group and Tongjingbao granules of control group both have therapeutic effects on dysmenorrhea of cold-damp stagnation type. Graphene waist protector can relieve the pain and its accompanying symptoms in patients with primary dysmenorrhea of cold-damp stagnation type.展开更多

To cope with this discrepancy owing to EMF steep reduction and understand the difference between type K heavy gauge sheathed thermocouple cables and small ones, the affects of EMF from sheath pipe, drawing times, annealing temperature, annealing time and annealing way were mainly studied and appropriately analyzed. The results show the change in the thermal EMF is related with the residual stress and crystal defects, which are imparted by cold work during manufacture. The affects of cold work can be removed by annealing. Finally, a feasible way of fabricating heavy gauge sheathed thermocouples was suggested according to practical situation.展开更多

Fatigue specimens were fabricated by laminating a supportive layer of 20-μm polyimide film to one side of the foil and patterning 242 crack initiation features by photolithographic process. Progression of fatigue damage was determined through electrical resistance measurement. The fatigue response was demonstrated to be largely affected by anisotropy existing between the rolling direction and the off-axis orientations. Fatigue cracks that traveled in a direction parallel to the elongated grains (cyclic loads applied at 90-degree orientation to foil rolling direction) had the most fatigue response (undesirable characteristic). The construction of the specimens with thin foil supported by a film backing contributed to high fatigue threshold.展开更多

Acupuncture and moxibustion therapy as an external treatment of traditional Chinese medicine for relieving stomach pain due to deficiency of spleen and stomach, has the advantages of convenient operation, small adverse reactions and remarkable curative effect, which is easy for patients to accept. In this paper, acupuncture and moxibustion therapy such as moxibustion and warm acupuncture therapy for stomach pain of spleen and stomach deficiency cold type is summarized to provide evidence-based basis for clinical treatment of stomach pain of spleen and stomach deficiency cold type.展开更多
