Effectiveness and safety of Xuefu Zhuyu oral liquid on -stagnation and blood-stasis pattern in patients with stable angina, tension-type headache and primary dysmenorrhea: rationale and design of a master protocol.

We present the rationale and design of a master protocol study that clarifies the effectiveness and safety of Chinese herbal formulas on -stagnation and blood-stasis pattern (QBP). Three randomized controlled trials (RCTs) and real-world observational studies. Based on three registry cohorts of stable angina, tension-type headache and primary dysmenorrhea, patients with QBP will be enrolled in RCTs to receive either Xuefu Zhuyu (, XFZY) oral liquid or a placebo, while patients with non-QBP will be enrolled in the observational studies and experience follow-up. 1414 patients (RCTs: 574; observational studies: 840) will be recruited at seven centers in China over a 3-year period. The primary outcome is the visual analog scale of pain intensity. Adverse events will also be reported. The analysis will be undertaken separately in each sub-study, and then an overall analysis combining multiple subgroups will be performed to comprehensively investigate the effect of XFZY oral liquid. This study will provide high-quality evidence of XFZY oral liquid for QBP patients and show a paradigm of post-marketing evaluation of the effectiveness and safety for Chinese medicine following the notion of the pattern dominating different disease research models.

Treatment of enlarged facial pores / 中华皮肤科杂志

Enlarged facial pores remain a common skin concern. Its occurrence is mainly associated with increased sebum production, skin aging (skin laxity and decreased skin elasticity) , increased hair follicle size and other factors, and current treatments for enlarged facial pores mainly target these factors. This review retrospectively summarizes current common treatments, including oral antiandrogens, topical retinoids, chemical peels, lasers, radiofrequency and focused ultrasound. The increasing development of photoelectric devices offers newer and more reliable choices.

A observation of early postoperative cognitive dysfunction and postoperative analgesia situation after intercostal nerve block was applied on elderly patient received thoracic surgery / 中国医学装备

Objective:To investigate the effect of early postoperative cognitive dysfunction and postoperative analgesia situation after intercostal nerve block was applied on elderly patient received thoracic surgery.Methods: 105 elderly patients underwent thoracic surgeries were divided into observation group (35 patients received intercostal nerve block combined with general anesthesia), control A group (35 patients received epidural anesthesia combined with general anesthesia) and control B group (35 patients received routine general anesthesia). The cognitive function, postoperative pain, intraoperative mean artery pressure (MAP) and heart rate of the patients among different groups were respectively compared.Results: The cognitive function scores in postoperative 12h, 24h, 72h of observation group were significantly higher than that of control A group (t=20.917,t=27.780, t=74.081,P<0.05), respectively. And all of these data also were significantly higher than that of control B group (t=37.922,t=48.969,t=62.653,P<0.05), respectively. The differences of MAP, HR value between observation group and control A group were statistically significant (t=18.927,t=22.380,P<0.05), respectively. And the differences of them between observation group and control B group also were statistically significant (t=31.051, t=19.932, P<0.05), respectively. Besides, the differences of pain scores in postoperative 6h, 12h, 24h, 48h between observation group and control A group were not statistically significant, while all of pain scores of observation group were significantly lower than that of control B group (t=18.731,t=19.035, t=21.093,t=17.036;P<0.05).Conclusion:Intercostal nerve block combined with general anesthesia can ensure more stable intraoperative vital signs for elderly patients underwent thoracic surgeries, and it contributes to improve early cognitive function and possesses better postoperative analgesic effect for elderly patients.

Observation on the effect of dexmedetomidine on regional cerebral oxygen saturation and postoperative cognitive function in elder patients received prostatectomy by using laparoscope / 中国医学装备

Objective: To research the effect of dexmedetomidine on regional cerebral oxygen saturation(rSO2)and postoperative cognitive function in elder patients received prostatectomy by using laparoscope. Methods: 60 elderly patients received prostatectomy by using laparoscope were divided into observation group (30cases) and control group (30cases) as random number table. In observation group, the dexmedetomidine was injected by venous pump after endotracheal intubation of general anesthesia was implemented, while the equivalent normal saline (NS) was injected by venous pump in control group. The rSO2, PaCO2 and PaO2 of different time point between the two groups were observed and compared. The usages of propofol and remifentanil, the situation of postoperative restlessness, and situation of nausea and vomiting between the two groups were compared. Besides, the scores of MoCA of different time point between the two groups also were compared. Results: The usages of propofol and remifentanil of observation group were significantly lower than that of control group (t=3.449, t=9.466, P0.05). The score of MoCA of observation group was significant higher than that of control group (t=8.938, P<0.05) at postoperative 1d. Conclusion: In the elder patients received prostatectomy by using laparoscope, the dexmedetomidine doesn't affect the rSO2 level of patients, while it contributes to fast recover the postoperative cognitive function of patients.
