Clinical observation on the time-effect relationship of moxibustion for primary dysmenorrhea due to stagnation and congelation of cold-damp / 针灸推拿医学（英文版）

Objective: To observe the time-effect relationship of moxibustion for primary dysmenorrhea (PD) due to stagnation and congelation of cold-damp, thus explore the optimal choice of moxibustion duration, and provide evidence for achieving satisfactory efficacy in moxibustion treatment. Methods: A total of 90 patients with PD due to stagnatin and congelation of cold-damp were divided into three groups by the random number table method, with 30 cases in each group. All the patients in the three groups were given moxibustion treatment at Guanyuan (CV 4), 20 min in group A, 40 min in group B and 60 min in group C. The changes in the pain measurement score in the three groups were observed after treatment. Results: After treatment, there were significant differences in the clinical efficacy among the three groups (P<0.05); the clinical efficacy was better in group B and group C than that in group A (P<0.05), and that in group B was better than that in group C (P<0.05). Besides, the pain measurement score changed significantly after treatment in the three groups (all P<0.05), and the between-group differences were also statistically significant (P<0.05); the pain measurement scores in group B and group C were lower than that in group A (P<0.05), and that in group B was lower than that in group C (P<0.05). Conclusion: Given the same stimulating frequency and intervention time of moxibustion, 40-minute duration demonstrates relatively better efficacy for PD due to stagnation and congelation of cold-damp.

Application of OCT in traumatic macular hole / 国际眼科杂志(Guoji Yanke Zazhi)

·AIM: To observe the application of optical coherence tomography ( OCT ) in the diseases of traumatic macular hole.·METHODS: Twenty - five eyes of 23 patients with traumatic macular hole from January 2015 to January 2017 were enrolled in this study, including 9 eyes treated without surgeries, 16 eyes with surgeries. The image features were analyzed using OCT from ZEISS.·RESULTS: The OCT characteristics in patients with traumatic macular hole were partial or full - thickness disappearance of the neuro-epithelium. Posterior vitreous detachment was not seen in the traumatic macular hole. OCT examination revealed that 4 eyes had partial detachment of macular hole and 21 eyes had full thickness detachment. Of the twenty-one eyes, 4 eyes had simple macular hole, 10 eyes had macular full-layer division with peripheral nerve epithelium edema, 7 eyes had the macular full - layer hole with the neuro - epithelium localized detachment. In the 25 eyes, 9 eyes did not undergo the surgery, of which 7 eyes were self-healing;16 eyes were surgically treated. Postoperative OCT showed the macular structure were normal in 12 eyes with the visual acuity improved 3 lines; retinal nerve epithelium were thinning in 4 eyes, visual acuities were not significant improved after surgery.·CONCLUSION: OCT examination is necessary for the diagnosis and treatment of traumatic macular hole.

Effects of sufentanil, remifentanil or fentanyl on cardiac output of elder patients during induction of general anesthesia / 中国基层医药

Objective To compare the effects of equivalent dose sufentanil,remifentanil or fentanyl on hemodynamic and cardiac output in the elderly patients during induction of general anesthesia.Methods Ninety elderly patients(ASA Ⅰ ～ Ⅱ) undergoing elective abdominal surgery under general anesthesia were randomly divided into sufentanil group(group S),remifentanil group(group R) and fentanyl group(group F),30 patients in each group.Patients in group S,group R and group F received sufentanil 0.2μg/kg,remifentanil 2μg/kg and fentanyl 2μg/kg Ⅳ,respectively,using an blind method before intubation.SBP,DBP,MAP,HR,CO,CI and SVR were recorded before of anesthesia (T0),immediately after induction (T1),1,3 minutes after tracheal intubation (T2,T3).Changes of SBP and HR during observation were also recorded.Results The MAP and HR in three groups at T1 were significantly lower than those at T0 and decreased significantly in group R than those in group F and S(P ＜0.05).The MAP and HR in group F significantly increased at T1 than T0.The MAP and HR in group R were significantly decreased after tracheal intubation.Compared with the baseline,the MAP and HR in group S at T1,T2,remained unchanged.In group R,there were two patients whose HR were under 50 bpm.In group F,the MAP at T1,T2 were significantly higher than those at T.In group S,there were no significant changes in CO,CI,SVR which were all within normal range (P ＞ 0.05).Conclusion Both sufentanil and remifentanil effectively inhibit the stress response during induction of general anesthesia.At the same time,sufentanil has better hemodynamic stability.
