Objective To compare the efficacy and safety of nicardipine versus urapidil in blood pressure (BP) management during the acute phase of intracerebral hemorrhage (ICH).Methods ICH patients admitted in Emergency Intensive Care Unit of Shenzhen People's Hospital from March,2013 through March,2016 were retrospectively studied.Patients were enrolled as nicardipine group or urapidil group depending on the initial antihypertensive drug given at admission.The differences in rate of patients reached the goal BP within the first 24 h,time required for getting goal BP,blood pressure variability (BPV),rebleeding or hematoma expansion during the first 24 h,cerebral state index (CSI) within 7 days and 28-day mortality were compared between the two groups.The differences in adverse events including bradycardia,tachycardia and hypotension were also compared between two groups.An independent t test and x2 test were performed to compare different variables.An analysis of variance of repeated measurement was performed to compare CSI within 7 days between two groups.Results Seventy-seven patients were included with 42 in nicardipine group and 55 in urapidil group.Rate of patients getting goal BP in nicardipine group was (94±5)％ and (86±11)％ in urapidil group (P＜0.01).Time required to get goal BP was (35 ± 28) min in nicardipine group and (52 ± 37) min in urapidil group (P =0.02).BPV was (11.23 ± 2.38) in nicardipine group and (13.16 ± 3.15) in urapidil group (P =0.003).Rebleeding or hematoma expansion rate during the first 24 h and 28-day mortality rate were comparable between the two groups (P ＞ 0.05).Through analysis of variance of repeated measurement,CSI in nicardipine group improves more rapidly than that in urapidil group (F =1 581.115,P =0.000).Hypotension,bradycardia and tachycardia were also comparable between groups (P ＞ 0.05).Conclusion Compared with urapidil,nicardipine produces effect more rapidly with more stable BP and higher rate of patients with ICH getting goal BP.Moreover,the application of nicardipine may be better to improve the CSI of ICH patients.

Myopia is an important public health issue.Great attention has been paid to myopia in children and teenager since its incidence is progressing rapidly worldwide, especially in Asia.Although there are substantial reports on both myopia progression and its risk factors in children and teenager, challenges are encountered when attempting to compare results among individual studies due to different population, definition of myopia, cycloplegic eye drops, refraction methods, and so on.This review aimed to summarize the reports on myopia progression and its risk factors such as age, gender, refractive state, near work, outdoor activities, parental myopia, or parental bearing age in children and teenager (＜18 years) since 1990.

Atherosclerosis is a chronic inflammatory disease commonly seen in clinical practice. It can lead to thickening of vascular intima, occlusion of lumen stenosis and thrombosis, leading to angina pectoris, hypertension, myocardial infarction and other diseases, posing a serious threat to human life and health. This study provides a method for removing shield needles from graphene oxide thrombus and its preparation. The graphene oxide shield needle mainly includes flexible rotating shaft, radial flexible rod, rotating needle, adsorption main pipe and dosing main pipe, laser measuring device, high definition camera and other structures, which has the following advantages:firstly, it achieves multi-angle rotation grinding thrombosis, precise rotation grinding, avoids vascular damage and infection; secondly, thrombolytic drugs can be applied in the process of rotary grinding and small thrombus can be adsorbed to effectively avoid secondary embolization of blood vessels; thirdly, it a coating of graphene oxide on a rotating needle, which protects against bacteria and infection. This study has practical reference value for the development of thrombotherapy and the application of graphene in the medical field.

Objective:To compare the effects between video-assisted thoracoscopic surgery (VATS) and conventional surgery in internal fixation of multiple rib fractures.Methods:Patients with multiple rib fractures, who were admitted to Emergency Center of Shenzhen People's Hospital from June 2010 to May 2020, were included. Patients were divided into the VATS group (incision positioning with VATS) and the conventional group (incisionpositioning with CT scan). The primary outcome measures was the risk of complications, and the secondary outcome measures included postoperative pain, incision length, operation time, and mechanical ventilation rate. Continuous and categorical variables were compared using LSD- t test and Chi-square test. Repeated measures analysis of variance was performed to assess the trend of postoperative pain over time. A logistic regression analysis was used to explore the association of VATS with postoperative complications. Results:A total of 221 patients, including 128 patients in the VATS group and 93 patitents in the conventional group, were enrolled. Baseline characteristics were identical between the two groups ( P>0.05). In the VATS group, the length of incision, intraoperative blood loss, operation time, mechanical ventilation rate after operation, ventilation time, thoracic tube indwelling time, ICU and total length of stay, and medical costs were better than those in the conventional group (all P<0.05). Repeated measures analysis of variance showed that pain relief was faster and more profoundly in the VATS group than in the conventional group ( F=3 517.808, P<0.01). Logistic regression analysis indicated that VATS was an independent protective factor for reducing postoperative complications ( OR=0.225, 95% CI:0.121-0.416, P<0.01). Conclusions:During internal fixation of multiple rib fractures, VATS is an effective approach to reduce postoperative pain and complications. Moreover, video-assisted technique is associated with a rapid recovery for patients, resulting in shorter length of hospital stay and less medical costs.
