RESUMO
Recommendation formation is a key component of clinical practice guidelines for Chinese patent medicine （CPM）， and should encompass the determination of the strength and direction of the recommendation， the rationale for the recommendation， and the methodology for implementing the recommendation. Recommendations can be formed through formal consensus and informal consensus. The strength and direction of recommendations for CPM guidelines should be determined by considering the quality of evidence for CPMs， the priority of the clinical questions， the pros and cons of efficacy and adverse effects， patient acceptance， the feasibility of the recommendation and the availability of resources， social fairness， economic benefits， and other influencing factors. In order to better guide guideline developers to consider these factors more rationally， this article provideed a detailed explanation of each factor in the context of the characteristics of TCM.
RESUMO
Objective:To investigate clinical characteristics and factors influencing the prognosis of patients with mucosal melanoma.Methods:The clinical data of 49 patients with mucosal melanoma in Fujian Cancer Hospital from March 2012 to March 2022 were retrospectively analyzed, and their clinical characteristics and prognostic influencing factors were observed. Kaplan‐Meier method was used for survival analysis and Cox proportional risk model was used to analyze the prognostic influencing factors.Results:Female accounted for 61.2% (30/49) of all 49 patients with mucosal melanoma and the median age was 56 years (42-79 years). The most frequent primary tumor sites occurred in head and neck (42.9%, 21/49), followed by the reproductive system (32.7%, 16/49). At the time of initial diagnosis, 81.6% (40/49) of patients had no distant metastasis and 79.6% (39/49) of patients had normal levels of peripheral blood lactate dehydrogenase. The median overall survival time of 49 patients with mucosal melanoma was 39.5 months (95% CI 23.1-55.9 months). The median overall survival time of patients without distant metastasis at the time of initial diagnosis was significantly longer than that of patients with distant metastasis [46.5 months (95% CI 31.6-61.4 months) vs. 19.2 months (95% CI 0-42.2 months, P = 0.025]. There were no statistically significant differences in median overall survival time of patients with different gender, age at the time of initial diagnosis, primary tumor site, and the level of lactate dehydrogenase in peripheral blood at the time of initial diagnosis (all P > 0.05). The presence of distant metastasis at the time of initial diagnosis was an independent risk factor for the prognosis of patients with mucosal melanoma ( HR = 0.379, 95% CI 0.157-0.918, P = 0.032). Conclusions:Mucosal melanoma is more common in female. The most frequent primary tumor sites occur in head and neck. At the time of initial diagnosis, most patients have non‐distant metastasis and the normal level of peripheral blood lactate dehydrogenase. At the time of initial diagnosis, whether there is distant metastasis is an independent influencing factor for the prognosis of patients with mucosal melanoma.
RESUMO
Objective:To investigate the application of ultrasound imaging in evaluating the curative effect of patients with nutcracker syndrome (NCS) treated with three-dimensional(3D) printing extravascular titanium stents.Methods:From December 2015 to December 2018, a total of 41 NCS patients enrolled in the Second Affiliated Hospital of the Air Force Military Medical University to receive 3D-printing extravascular titanium stents treatment were included in this study. Ultrasound and CT angiography (CTA) were performed before and 1 week after operation to evaluate the compression of left renal vein and related hemodynamic changes.Results:Before the operative, the ultrasound examination showed that the angle between the abdominal aorta and superior mesenteric artery was (21.29±4.53)°, which was significantly improved in 1 week after treatment [(47.42±7.45)°, P<0.001]. Left renal vein was significantly compressed before treatment, with the smallest inner diameter of (1.51±0.49)mm and its peak blood flow velocity was (143.92±50.40)cm/s. Postoperative ultrasound images showed the significant expansion of left renal vein and no high velocity blood flow was observed. Ultrasound examination also showed that the diameter of left renal vein at renal hilum, blood flow velocity at renal hilum and inner diameter of spermatic vein were significantly improved after treatment ( P<0.001). Similar to ultrasound results, CTA also found that the angle between abdominal aorta and superior mesenteric artery increased significantly after treatment[(17.59±4.56)° vs (52.27±9.01)°, P<0.001]. CTA also showed the left renal vein was compressed before treatment, with the smallest inner diameter of (2.09±0.86)mm, and it was significantly expanded after operation. The inner diameter of left renal vein at renal hilum was also significantly reduced after treatment ( P<0.001). Conclusions:Ultrasound imaging can effectively evaluate the LRV compression and related hemodynamic changes before and after 3D printed stent implantation treatment in NCS patients and provide a reliable method to evaluate its clinical efficacy for these patients.
RESUMO
To evaluate the accuracy of transcranial color‐code sonography ( TCCS) in non‐invasive assessment of intracranial pressure( ICP ) . TCCS was used to monitor the cerebral hemodynamic parameters of patients with acute severe traumatic brain injury after decompressive craniectomy and make estimation of the non‐invasive intracranial pressure ( ICPtccs) . Methods A total of 91 patients with acute severe traumatic brain injury involved in this retrospective study were divided into the ICP normal group( ≤22 mm Hg ) and the ICP increased group ( ＞22 mm Hg ) . T he correlation and consistency of middle cerebral artery blood flow parameters and ICPtccs with invasive intracranial pressure ( iICP ) were analyzed . According to Glasgow score ( GCS) ,Patients( GCS 3－8) were divided into acute extremely severe traumatic brain injury( GCS 3 －5) and acute severe traumatic brain injury ( GCS 6 －8 ) . A comparison was made of ROC ( ICPtccs) curve and the area under the curve( AUC) between the two groups were cornpared . Results①No statistical differences were found in cerebral hemodynamic parameters between the side with and without decompressive craniectomy in patients with acute severe traumatic brain injury ( all P ＞0 .05 ) . ②M onitored resistive index ( RI) ,pulsatility index ( PI) and ICPtccs between the normal ICP group and the increased ICP group showed statistically significant differences ( all P ＜ 0 .05 ) ,w hile monitored systolic velocity ,diastolic velocity and mean velocity presented no statistically significant difference ( all P ＞0 .05) . T he correlations between RI ,PI with iICP were low ( r＝ 0 .247 ,0 .221 ; all P ＜ 0 .05 ) ,w hile there was a moderate correlation between ICPtccs and iICP( r ＝0 .417 , P ＜0 .001 ) . ③Bland‐Altman plot showed an overestimation of 2 .3 mm Hg ( 95% CI 0 .00－4 .59 mm Hg ) for ICPtccs compared to iICP . ④T he AUC of Glasgow score ( GCS 3－5 and GCS 6－8) in the two groups were 0 .759 ,0 .781 ( all P ＜0 .05) . All the cut‐off points of ICPtccs were 19 mm Hg ,with a sensitivity of 83 .33% ,81 .82% and a specificity of 64 .86% , 75 .68% ,respectively . Pairwise comparison of two AUCs showed no statistical difference ( P ＝ 0 .476) . ICPtccs presented the same ability to estimate ICP in patients with acute severe and extremely severe traumatic brain injury . TCCS could accurately assess the elevation of ICP in 72 .52% patients with acute severe traumatic brain injury . Conclusions TCCS can be used as a non‐invasive screening tool to assess w hether ICP of patients with acute severe traumatic brain injury is elevated and to semi‐quantitatively estimate ICP ,showing useful clinical value .
