This study was aimed to observe the effect ofRong-Shuan (RS) capsule on rodent tolerance against cerebral ischemia, hypoxia and cerebral reserve capacity, which was related to promote blood circulation and remove blood stasis. Acute cerebral ischemia and anoxia models were established by permanent left carotid artery ligation on C57 BL/6 mice and hypoxia inhalation (O2?N2 = 8?92) for 15 min. Duodenal administration of RS capsule at different doses (100, 200 or 400 mg·kg-1) or saline were given 10 min after ischemia onset. The local brain blood circulation changes and neurobehavioral function were evaluated 24 h after ischemia onset. SD rats were given RS capsule at different doses (75, 150, 300 mg·kg-1) or saline. The effect of RS capsule on improvement of microcirculation disturbance induced by high molecular dextran was observed. The results showed that compared with the sham operation group, the brain blood circulation in the model group was significantly decreased; the cerebral infarction area increased; and the behavioral score after cerebral hypoxia was significantly increased (P < 0.05, orP < 0.01). Meanwhile, after the injection of high molecular dextran among rats in the model group, the cerebral leptomeninx microcirculation was obviously slowed down at 3 timepoints, which were 10, 20 and 30 min. Compared with the model group, RS capsule (400 mg·kg-1) can significantly increase the local blood circulation in the brain of mice, improve behavioral disturbance, reduce cerebral ischemia area (P< 0.05, orP < 0.01). RS capsule can also improve blood flow velocity and flow pattern in cerebral leptomeninx microcirculation disturbance induced by high molecular dextran at different timepoints (P < 0.05, orP < 0.01). It was concluded that RS capsule can increase the tolerance against cerebral ischemia, hypoxia and cerebral reserve capacity in order to protect the neural tissues to promote neuronal recovery.

Objective To compare expression of Toll?like receptors 7 and 9(TLR7, TLR9)as well as their regulatory molecules myeloid differentiation factor 88(MyD88)and nuclear factor?κB(NF?κB)in peripheral blood mononuclear cells(PBMCs)between patients with vitiligo and healthy individuals, and to explore their significance. Methods Flow cytometry was performed to measure expression of TLR7 and TLR9 in PBMCs among 36 patients with vitiligo and 22 healthy controls, and real?time fluorescence?based quantitative PCR(RT?PCR)was conducted to determine mRNA expression of MyD88 and NF?κB in the above blood samples. Results Compared with healthy controls, patients with vitiligo showed higher expression of TLR7 and mRNA expression of MyD88 and NF?κB, but lower expression of TLR9. However, significant differences were only observed in the mRNA expression of NF?κB(t=2.814, P=0.008), but not in the expression of TLR7 and TLR9 or the mRNA expression of MyD88 between patients and controls (t = 1.477, 1.761, 0.058, all P > 0.05). Conclusion NF?κB, as a key signaling molecule of TLR7 and TLR9 regulation pathways, increases obviously in patients with vitiligo, suggesting that NF?κB may be involved in the pathogenesis of vitiligo.

Objective:To evaluate the efficacy of dual-tuberosity locking plate for the treatment of proximal humeral fractures.Methods:This study retrospectively analyzed data of patients with proximal humeral fractures treated with a new locking plate from July 2017 to July 2019. Finally, 19 eligible patients were included, including 12 females and 7 males, with an average age of 64.0±12.8 years (range, 32-85 years). According to the Neer classification of proximal humeral fractures, 1 case was two-part fractures, 9 cases three-part fractures and 9 cases four-part fractures. Among them, 9 cases combined with greater and lesser tuberosities fractures and 10 cases with isolated greater tuberosity fractures. Constant-Murley and disabilities of the arm shoulder and hand (DASH) scores, the change of neck-shaft angle, the change of humeral head height, tuberosity consolidation and other complications were recorded at the latest follow-up.Results:The mean follow-up time was 16.1 months (range, 12-18 months). All fractures were healed within follow-up period. Mean Constant-Murley score was 84.2±11.0 (range, 55-98), DASH score was 19.4±11.6 (range, 2.3-47.8) and VAS was 1.6±1.3 (range, 0-4) at the latest follow-up. As for the radiographic results, 19 patients had a mean neck-stem angle of 141.9°±9.8° (range, 132.17°-162.66°) on the first day after surgery, and a mean humeral head height of 18.0±5.9 mm (range, 7.45-27.12 mm). The mean neck-stem angle was 148.6°±7.5° (range, 132.70°-159.39°) and the mean humeral head height was 17.4± 5.5 mm (range, 5.02-27.31 mm) at the latest follow-up. The average change of neck-stem angle was 3.29° (range, 0.68°-33.10°), and mean change of humeral head height was 0.68 mm (range, 1.32-6.56 mm). No fractures developed greater or lesser tuberosity absorption or malunion, but 4 cases suffered loss of fixation and 1 developed primary intra-articular screw penetration as well as wound infection.Conclusion:In the open reduction and internal fixation of the proximal humeral fractures, the new locking plate can fix greater and lesser tuberosity fractures simultaneously, which helps reduce their displacement and deformity of tuberosities. By given that, satisfactory radiographic outcomes and shoulder functions can be obtained.

Objective:To learn the key driving factors in the management of scientific and technological achievements transformation in public hospitals, so as to provide basis for improving the effectiveness of achievements transformation.Methods:From March to July 2021, 1 226 medical staff from 7 municipal hospitals in Hangzhou were investigated by stratified random sampling. The questionnaire included the main demographic information, the perceived importance and actual performance of the management mechanism(6 dimensions, 18 items)which was scored by Likert 5. Descriptive analysis was carried out and paired samples were compared by t-test, and the difference was significant when P<0.05. Importance matrix analysis was carried out on all items to identify the key driving factors for the transformation of achievements in public hospitals. Results:1 157 valid questionnaires were finally included. The difference between the scores of perceived importance and actual performance of the various management mechanisms was significance( P<0.001). The gap was presented as follows: evaluation mechanism(1.29), investment mechanism(0.88), organization and leadership mechanism(0.87), guarantee mechanism of services(0.44), benefit and distribution mechanism(0.15), incentive mechanism(-0.11). Matrix analysis results showed that, " special funds support" , " grasp market demand and accurately connect" , " formulate corresponding supporting systems" , " professional transformation team with multidisciplinary background" , " classified and multi-level achievement transformation evaluation index system" , " full life cycle management" , " incorporate into central work and key tasks" and " scientific and technological achievement transformation reporting system and application monitoring system" were the key driving factors for the transformation of scientific and technological achievements in public hospitals. Conclusions:The perceived importance of medical staff to the transformation of scientific and technological achievements in public hospitals is acceptable, while the actual performance is relatively weak. The management effectiveness should be improved and give priority to consolidate the management foundation, build index evaluation system, provide the life cycle management service and improve scientific interaction as well as consultation service mechanism.

Objective:To investigate the effects of exercise prescription on quality of life in patients with pituitary adenomas after surgery.Methods:A total of 82 patients with pituitary adenomas who met the inclusion criteria from December 2017 to September 2018 were enrolled. The control group received routine nursing care. The intervention group was given exercise prescription on the first day after surgery and 3 months after discharge from hospital. Both groups of patients completed the Health Status Survey(SF-36) before and after the intervention.Results:Before the intervention, there was no significant difference in baseline date of patients between two groups( P>0.05). After intervention, the general health dimension score (53.03±11.30) of the control group was significantly higher than the score within the group before treatment ( Z value was -4.398, P<0.05). The physiological function (86.67±7.46), physical function (66.67±29.28), role-emotional (71.30±22.75), vitality (68.33±8.78), general health dimension (61.39±10.66) of the intervention group were significant higher than the score within the group before treatment ( Z values were -4.809--2.041, P<0.05) . After the intervention, the significant difference were found in role-physical, general health, vitality, social function(77.18±15.71) and physiological health dimensions (73.75±10.00) between the intervention and control group ( Z values were -3.122- -2.467, t value was 3.044, P<0.05). After the intervention, non-function patients′ physiological function (72.06±23.19), general health (60.59±10.75), vitality (69.71±10.23) and social function (81.04±10.22) were significantly higher than the control group ( Z values were -2.832- -2.059, P<0.05).
