  • Retrospective analysis on treatment in twenty-four patients of renal artery aneurysm

    ObjectiveTo retrospective summarize the experience of endovascular repair and open surgery in the treatment of renal aneurysms in our single center.MethodsClinical data of 24 patients with renal aneurysm treated in our hospital from August 2012 to May 2018 were analyzed retrospectively. Nine patients undergoing surgical intervention were categorized as the open operation group, and ten patients who received endovascular repair were classified as the endovascular repair group. To compare and analyze the results of the two groups. Five patients who had refused surgery therapy will be analyzed separately.ResultsTwenty-four patients with seventeen females (70.8%) and seven males (29.2%) were enrolled in this study and nineteen patients with twenty-three aneurysms got repaired successfully. The endovascular repair group had shorter hospital stay compared with the open operation group [median: 10.5 (P25 6.3, P75 15.0) d vs. 21.0 (P25 17.0, P75 27.5) d]. One patient in the open operation group developed renal artery stenosis at 11 months after surgery and underwent reoperation by repair by successful stent placement. There were no other significant postoperative complications occurred in the two groups. No abnormal enlargement or rupture of the aneurysms were observed during the follow-up period in 5 unoperated patients.ConclusionsBoth open surgery and endovascular repair are effective means of treating renal artery aneurysms. Once the renal aneurysm ruptures, serious consequences will occur. Once a renal aneurysm is diagnosed, regardless of the size of the aneurysm, active surgical treatment is recommend.

  • Lung Protection Effect of Hypertonic Saline for One-lung Ventilation Patients

    【摘要】 目的 通过观察单肺通气患者术中氧合指数(oxygenation index,OI)、呼吸指数(respiratory index,RI)及动态肺顺应性(dynamic lung compliance,Cdyn)的变化,探讨高渗氯化钠溶液对术中单肺通气患者的肺保护作用。 方法 选择2009年12月-2011年2月完成的美国麻醉师协会分级为Ⅰ~Ⅲ级,心肺功能筛查、血常规、肝肾功能及凝血功能无明显异常,拟在全麻双腔气管插管下行开胸手术,术中需行单肺通气患者60例,随机分为高渗氯化钠组(A组)和对照组(B组),每组30例。A组在开始单肺通气后30 min快速输注7.5%高渗氯化钠溶液2 mL/kg,15 min内输注完毕,B组输注等量生理盐水,分别记录输注前(T1)、输注完毕时(T2)、输注后30 min(T3)、输注后1 h(T4)的OI、RI及Cdyn变化,并比较两组各时间点生命体征变化。 结果 两组患者OI、RI及Cdyn在T1、T2时差异无统计学意义(Pgt;0.05);两组患者不同时间点平均动脉压、心率、脉搏血氧饱和度、中心静脉压、呼气末CO2分压比较差异无统计学意义(Pgt;0.05);A组患者在T3、T4时的OI和Cdyn较B组明显升高,RI明显降低(Plt;0.05);且A组患者在T3、T4时的OI和Cdyn较T1时明显增高,RI明显降低(Plt;0.05)。 结论 高渗氯化钠溶液能改善术中单肺通气患者的OI、RI及Cdyn,对肺功能有一定的保护作用。【Abstract】 Objective To observe the oxygenation index (OI), respiratory index (RI) and dynamic lung compliance (Cdyn) changes of the patients with one-lung ventilation, in order to determine if hypertonic saline has lung protective effects. Methods Sixty ASA Ⅰ-Ⅲ patients who needed one-lung ventilation during thoracotomy under general anesthesia with double-lunmen endotracheal tubes were chosen to be the study subjects. No obvious abnormalities were detected by cardiopulmonary function screening, blood test, hepatorenal function and blood coagulation examinations in these patients. They were randomly divided into hypertonic saline group (group A) and control group (group B) with 30 patients in each group. For patients in group A, 30 minutes after one-lung ventilation, infusion of 7.5% hypertonic saline solution at 2 mL/kg was carried out and completed in 15 minutes. For patients in group B, the same amount of saline solution was infused. We recorded OI, RI and Cdyn changes before the infusion (T1), on the completion of the infusion (T2), 30 minutes after the infusion (T3), and 1 hour after the infusion (T4). The changes of vital signs in patients of the two groups were compared. Results OI, RI and Cdyn were not significant different between the two groups at T1 and T2 (Pgt;0.05). Mean arterial pressure (MAP), heart rate (HR), SpO2, central venous pressure (CVP), and PetCO2 were not significant different between the two groups at all time points (Pgt;0.05). OI and Cdyn of group A patients were significantly higher than those of group B, while RI was significantly lower at T3 and T4 (Plt;0.05). Cdyn and OI of group A patients at T3 and T4 were significantly higher when compared with T1, and RI was significantly lower (Plt;0.05). Conclusion Hypertonic saline has the lung protection effect in patients with one-lung ventilation by improving OI, RI and Cdyn.

  • NEUROPROTECTIVE EFFECTS OF MANGIFERIN ON ACUTE SPINAL CORD INJURY IN RATS AND ITS MECHANISM

    ObjectiveTo investigate the protective effect of mangiferin on acute spinal cord injury (SCI) in rats and its mechanism. MethodsNinety Sprague Dawley rats were randomly divided into 5 groups, 18 rats in each group. SCI was induced by using the Allen's method (60 g/cm) at T9 level in the rats of groups B, C, D, and E; laminectomy was performed at T8-10 in group A. The rats were injected intraperitoneally with saline in groups A and B, and with mangiferin in groups C (10 mg/kg), D (25 mg/kg), and E (50 mg/kg) every day for 30 days. The survival condition of rats was observed after operation; at 24, 48, and 72 hours after operation, the motor function of the hind limb was evaluated by the Basso, Beattie, Bresnahan (BBB) scores. The spinal cord edema was assessed by measuring the water content in spinal cord tissues at 72 hours. Meanwhile, malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH) were detected by ELISA; nuclear factor κB (NF-κB), tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and IL-6 were measured via ELISA at the same time. Caspase-3 and Caspase-9 were also detected by ELISA after mangiferin treatment for 30 days. The expressions of Bax and Bcl-2 proteins were detected by Western blot. Pathological changes of the spinal cord was observed by HE staining. And Caspase-3 protein expression was detected by immunohistochemical staining. ResultsAll rats survived to the end of experiment. BBB scores of groups B, C, D, and E were significantly less than that of group A (P < 0.05), and it showed an increase trend from groups B to E (P < 0.05). The content of water of groups B, C, D, and E were significantly greater than that of group A (P < 0.05), and it showed a decrease trend from groups B to E (P < 0.05). ELISA showed that the activities of MDA, NF-κB, TNF-α, IL-1β, IL-6, Caspase-3, and Caspase-9 in groups B, C, D, and E were significantly greater than that in group A (P < 0.05), and they showed decrease trends from groups B to E (P < 0.05). Meanwhile, the activities of CAT, SOD, and GSH in groups B, C, D, and E were significantly less than that in group A (P < 0.05), and they showed increase trends from groups B to E (P < 0.05). Western blot showed that the relative expression of Bax protein in groups B, C, D, and E were significantly greater than that in group A (P < 0.05), and it showed a decrease trend from groups B to E (P < 0.05). Meanwhile, the relative expression of Bcl-2 protein in groups B, C, D, and E were significantly less than that in group A (P < 0.05), and it showed an increase trend from groups B to E (P < 0.05). Histological observation showed that the pathological changes in group B were accord with that in SCI, and the degree of necrosis in groups C, D, and E were significantly improved when compared with that in group B, and the effect was better in group E than group D, and group D than group C. Immunohistochemical staining showed that the absorbance (A) value of Caspase-3 in groups B, C, D, and E were significantly greater than that in group A (P < 0.05), and it showed a decrease trend from groups B to E (P < 0.05). ConclusionMangiferin has neuroprotective effects on acute SCI in rats by alleviating edema of spinal cord, inhibiting oxidative stress and inflammation response, and regulating the Bcl-2 and Bax pathway.

  • Research progress of greater tubercle fixation and rotator cuff repair in humeral head replacement

    ObjectiveTo summarize the research progress of the greater tubercle fixation and the rotator cuff repair in humeral head replacement.MethodsThe literature about proximal humerus fracture and humeral head replacement in recent years was extensively consulted and analyzed.ResultsThe greater tubercle fixation and the attached rotator cuff repair have great influence on the function of shoulder joint after humeral head replacement. It is difficult to make an objective comparison because of lack of direct comparison between various methods, unified standards of grading, and limited number of cases.ConclusionIt is an important factor of reduction and fixation of greater tubercle to obtain better effectiveness in humeral head replacement. However, one-stage repair of rotator cuff is more important than greater tubercle fixation for functional recovery of shoulder joint.

  • Interpretation of 《Integrated Traditional Chinese and Western Medicine Practice Guidelines for Diagnosis and Treatment of Acute Pancreatitis》

    Integrated traditional Chinese and Western medicine has been used to treat acute pancreatitis (AP) for more than 50 years. It has become a dominant and specialized disease treated by integrated traditional Chinese and Western medicine. After many years of clinical practice, a relatively mature and complete treatment system has been formed. Therefore, it was proposed by the Chinese Society of Integrated Traditional Chinese and Western Medicine, the Chinese Medical Association, and the Chinese Association of Traditional Chinese Medicine to update and formulate the “Guidelines for the Diagnosis and Treatment of Acute Pancreatitis with Integrated Traditional Chinese and Western Medicine” (2021) group standards in 2022, and “Integrated Traditional Chinese and Western Medicine Practice Guidelines for Diagnosis and Treatment of Acute Pancreatitis” finally published. The guideline condenses 25 kinds of important clinical issues, which guide to explain the diagnosis and treatment of AP in detail, focusing on the integration of traditional Chinese medicine and Western medicine in the management of AP, such as staging and syndrome differentiation, early fluid therapy, pain management, and organ function support in early stage. The advantages and the timing of early intervention of traditional Chinese medicine in AP are emphasized. This guideline also proposes suggestions on nutritional support, management of causes, treatment of late local complications and infections, as well as prevention of recurrence and follow-up strategies for long-term complications. This paper provides an interpretation of this guideline.
