ObjectiveTo investigate the feasibility, safety, and clinical value of endoscopic-assisted skin-sparing mastectomy combined with immediate implant-based breast reconstruction performed as day surgery for breast cancer, aiming to provide a reference for major hospitals seeking to implement a day surgery model for breast cancer treatment. Methods We retrospectively analyzed 222 patients who underwent endoscopic-assisted skin-sparing mastectomy combined with immediate implant-based breast reconstruction for breast cancer at West China Hospital of Sichuan University from June 2021 to December 2022 were included, and were divided into a day surgery group and a conventional inpatient group based on their admission model. The operative indicators, Breast-Q scores, preoperative waiting time, length of hospital stay, hospitalization costs and complications of the two groups were analyzed. ResultsExcept for intraoperative bleeding (P=0.007), the difference between the two groups in comparison of the rest of the operative indicators was not statistically significant (all P>0.05); there was no significant difference between the two groups in preoperative and postoperative Breast-Q scores (all P>0.05); the preoperative waiting time and length of stay in hospital of the day surgery group were 4.0 (3.0, 11.0) and 1.0 (1.0, 1.0) days, respectively, which were significantly shorter than that of the conventional inpatient group; except for postoperative pain scores (P<0.001), there was no statistically significant difference in complications between the two groups (all P>0.05).ConclusionEndoscopic-assisted skin-sparing mastectomy combined with immediate implant-based breast reconstruction in day surgery is feasible and safe.Without increasing postoperative complications, it effectively reduces hospitalization costs and shortens medical care time, demonstrating significant clinical value.
Assessing the clinical value of pharmaceuticals is crucial for comprehensive evaluation in clinical practice and plays a vital role in supporting decision-making for drug supply assurance. Real-world data (RWD) offers valuable insights into the actual diagnosis and treatment processes, serving as a significant data source for evaluating the clinical demand, effectiveness, and safety of drugs. This technical guidance aims to elucidate the scope of application of RWD for the clinical value assessment of pharmaceuticals, as well as the key considerations for conducting value assessment research. These considerations include identifying the dimensions of clinical value that necessitate RWD and effectively utilizing RWD for evaluation purposes. Additionally, this guidance provides essential points for implementing pharmaceutical clinical value assessment based on real-world data, with a specific focus on study design and statistical analysis. By doing so, this guidance assists researchers in accurately comprehending and standardizing the utilization of real-world research in conducting pharmaceutical clinical research.
ObjectiveTo investigate the diagnostic value of serum cystatin-C (Cys-C) detection in hypertensive disorder complicating pregnancy patients. MethodsA hundred patients with pregnancy induced hypertension (PIH) were chosen as the research object from February 2012 to March 2013, and they were divided into mild group, moderate group and severe group according to the severity of the disease. The other 40 healthy pregnant women were selected as the controls (the control group). We compared the four groups in terms of Cys-C, serum urea nitrogen (BUN) and creatinine level, as well as the positive rate of Cys-C, BUN, and creatinine. ResultsCys-C, BUN, and creatinine in the PIH group were significantly higher than those in the control group (P<0.05). Cys-C and creatinine in preeclampsia mild group were significantly higher than those in the control group (P<0.05), but BUN level between the two was not statistically significant (P>0.05). Cys-C, BUN, and creatinine in the PIH moderate and severe groups were significantly higher than those in the control group (P<0.05). The abnormal rate of Cys-C in the PIH mild group was significantly higher than that of Cys-C and creatinine (P<0.05). ConclusionCys-C, BUN and creatinine can all show renal damage in PIH patients, but the Cys-C value in early diagnosis is better than that of BUN and creatinine. It can be used as a monitoring index of pregnancy-induced hypertension prevention and early treatment.
With the advancement of modern research in traditional Chinese medicine (TCM), evidence regarding the clinical efficacy and mechanisms of action of TCM has rapidly accumulated. However, due to a lack of methodological safeguards, the disconnection between clinical and basic research in TCM has become increasingly prominent, making it difficult to form an evidence chain that supports the scientific value of TCM in a manner that is "clear and understandable". Therefore, it is necessary to develop methods for the translation and integration of clinical and basic research evidence oriented towards clinical value, to form a reliable evidence chain that can further discover patterns, confirm efficacy, and highlight advantages. This article discusses the construction and evaluation methods of the evidence chain for the efficacy of TCM, aiming to provide theoretical and methodological references for related work.
摘要:目的:动态监测急性胰腺炎(AP)患者外周血C反应蛋白(CRP)水平,探讨CRP对AP的早期诊断与病情评估的参考价值。方法:分别检测75例SAP患者和75例 MAP患者入院后第1、3、5、7、9天外周血CRP水平,并进行分析比较。结果: MAP组患者CRP高峰值出现在住院第3天,第7天开始下降,14天后恢复正常。而SAP组患者住院第1天即可出现CRP显著增高,且下降速度缓慢,在后期CRP仍可维持在一个较高水平。入院第1天,SAP组血清CRP水平均显著高于MAP组(Plt;0.01)。轻症与重症组(无并发症或有并发症)之间患者血清CRP水平差异均有高度显著性(Plt;0.01)。结论: 动态监测CRP可作为AP早期诊断、疾病严重程度评估及预后判断的一个独立的衡量指标,值得临床推广应用。Abstract: Objective: To dynamic monitoring of acute pancreatitis (AP) in patients with Creactive protein (CRP) levels, CRP on the AP to explore the early diagnosis and prognostic evaluation of the reference value. Methods: 75 cases of SAP patients were examined and 75 patients with mild acute pancreatitis (MAP) after admission in patients with CRP levels in peripheral blood 1,3,5,7,9 days, and conduct analysis and comparison of. Results:MAP peak value of CRP in patients in hospital the first 3 days, 7 day drop in 14 days after return to normal. The SAP Group 1st day of hospitalization was significantly higher CRP can occur, and the rate of decline is slow, in the latter part of CRP can be maintained at a high level. Admission day 1, SAP serum levels of CRP were significantly higher than the MAP group (Plt;0.01). Between mild and severe group, no complications and complications in patients with serum CRP levels of SAP differences were highly significant (Plt;0.01). Conclusion:Dynamic monitoring of CRP can be used as AP early diagnosis, disease severity assessment and prognosis of an independent measure worthy of clinical application.
ObjectiveTo explore the clinical value of transthoracic echocardiography (TTE) in the diagnosis of infective endocarditis. MethodsWe retrospectively analyzed the transthoracic echocardiogram in 35 patients with infective endocarditis confirmed between September 2003 and September 2013. Patients underwent routine heart scan in all sections to measure sizes of all chambers and cardiac function, observe morphologies, activities and functions of all valves and ventricular walls, and diagnose whether underlying heart diseases exist, focusing on intracardiac vegetations and their distributions, morphologies, sizes, numbers, echoes and activities, and a full analysis of the blood culture findings was also conducted. ResultsOf the 35 patients undergoing initial TTE, 29 were positive, and 6 were negative (2 positive and 4 negative in the reexamination one week later). Vegetations were found in the mitral valve (8/35), aortic valve (15/35), tricuspid valve (5/35), pulmonary valve (1/35), pulmonary arterial wall (1/35) and right ventricle (1/35), respectively. There were 29 (8 and 21 with congenital and acquired heart diseases, respectively) and 6 patients with and without underlying heart diseases, respectively. Of the 35 blood cultures, 33 were positive and 2 were negative. ConclusionsTTE is rapid and accurate for early diagnosis of infective endocarditis, precise localization and rough quantification of vegetations, determination of whether valve damage occurs and what its severity is, and detection of whether complications exist. It is valuable for early diagnosis, treatment, follow-up and prognosis judgment.
