腮腺切除术中沿面神经总干顺行解剖面神经的效果及安全性

目的探讨腮腺切除术中应用沿面神经总干顺行解剖面神经的治疗效果及安全性。方法选取我院2016年2月至2019年3月收治的60例择期行腮腺切除术的患者,随机分为观察组与对照组各30例。对照组沿面神经总干逆行解剖面神经,观察组沿面神经总干顺行解剖面神经,观察两组患者术后1个月面神经功能及术后并发症发生情况。结果术后1个月,两组患者的面神经功能分级比较无统计学差异(P>0.05);观察组的术后并发症发生率为10.00%,明显低于对照组的33.33%(P <0.05)。结论临床行腮腺切除术中,沿面神经总干顺行解剖面神经可降低术后并发症发生率,值得推广。

ENDOSCOPIC PANCREATIC STENTING IN CHRONIC PANCREATITIS WITH DUCTAL DILATION PROXIMAL TO A STRICTURE: A SAFE and EFFECTIVE PROTOCOL

After removal of intraductal stones, a 10‐Fr or 7‐Fr pancreatic stent was placed in 16 patients with upstream ductal dilation proximal to a stricture of the main pancreatic duct. Stents were removed after a mean duration of 52.5 days. Nine patients underwent repeated stenting. About one year after removal of the initial stent, when the remaining upstream ductal dilation was found on follow‐up pancreatograms, the next stent was replaced. Repeated stenting improved outflow of pancreatic juice more effectively than one‐time stenting. Correlation between long‐term pain relief without recurrence of intraductal stones and reduction of duct diameter was also shown. Stent occlusion was observed in 14 of 30 stents. Stent occlusion was frequently associated with recurrence of pancreatitis and intraductal stones, and was also associated with morphologic changes in the pancreatic ductal system. Although there were no significant differences between stent patency of the initial stents and that of the next stents, stent patency of 10‐Fr stents was superior to that of 7‐Fr stents. 10‐Fr stents should be removed within 8 weeks and 7‐Fr stents should be removed within 4 weeks for the prevention of stent occlusion. Repeated stenting with short‐term stenting is therefore considered a safe and effective protocol of endoscopic pancreatic stenting.

Mechanical emergency recanalization of the left main coronary artery

Acute occlusion of the left main coronary artery is normally fatal. According to the literature, only a few cases have been treated by intracoronary thrombolysis; the prolonged period of ischemia, however, resulted in severe left ventricular dysfunction and numerous complications. Therefore, effort should be directed to recanalize the left main coronary artery within the shortest possible interval. We followed this approach in a case of acute occlusion of a subtotal stenosis of the left main coronary artery which could be mechanically reopened and dilated within a few minutes. The intervention resulted in immediate reversal of profound cardiogenic shock and complete restoration of normal left ventricular function. At hospital discharge, the patient was asymptomatic with a negative bicycle stress test. Immediate mechanical recanalization and angioplasty appear to be a feasible approach in life-threatening coronary occlusion.     

不同病因腹泻病儿肠道主要菌群变化的研究和比较

对８８例不同病因腹泻儿肠道双歧杆菌、乳酸杆菌、大肠杆菌的变化进行研究。对照组２５例。结果：研究组较对照组双歧杆菌、乳酸杆菌有显著下降（Ｐ＜０．０１和Ｐ＜０．０５），大肠杆菌下降不明显（Ｐ＜０．０５）。非感染性腹泻组较感染性腹泻组双歧杆菌、乳酸杆菌下降更显著（Ｐ＜０．０１和Ｐ＜０．０５），大肠杆菌下降不显著（Ｐ＜０．０５）。感染性腹泻组中，双歧杆菌在轮状病毒肠炎组中较急性菌痢下降更显著（Ｐ＜０．０５），而其它两种菌下降程度相差不明显（两者Ｐ＜０．０５）     

The Impact of Family Relations on Caregivers' Positive and Negative Appraisal of Their Caretaking Activities

This study examined the impact of family support and relationship difficulties between the caregiver and the care recipient on caregivers' satisfaction received from caregiving activities and subjective burden. Ninety‐seven individuals caring for a spouse or an adult child with schizophrenia or bipolar disorder participated in the study. Using hierarchical multiple regression analyses, findings showed that relationship difficulties between the caregiver and the care recipient were associated with both satisfaction received from caregiving activities and subjective burden, after the effects of personal, contextual, and stressor variables were controlled. Family support was not associated with caregivers' appraisal of the situation.
