Objective To compare the perioperative outcomes and long-term therapeutic response of laparoscopic splenectomy versus open splenectomy for idiopathic thrombocytopenic purpura.Methods A retrospective analysis of 124 patients who under-went splenectomy(68 LS and 56 OS)for ITP between January 2011 and January 2015 was conducted.Results Patients undergoing LS were found to require a longer operative time(P <0.05 )but had reduced hospital stay,lower intra-operative blood loss(P <0.05),less postoperative pain,earlier drain removal,and decreased incidence of complications(P <0.05).Conversion to OS was re-quired in 4 patients for excessive loss of blood(5.8%).Deep venous thrombosis(DVT)was observed in 1 patients after OS.One pa-tient died from pneumonia after LS.Mean follow-up of (33±11.8)months was performed in LS group and of (32±12.9)months in OS group.50 patients(73.5%)in LS group and 43(76.7%)in OS group reached sustained complete haematological response(P >0.05).Kaplan-Meier analysis showed that there was no significant difference in the relapse-free survival rate between the groups (P =0.679).Conclusion Compared with open splenectomy,laparoscopic splenectomy for patients with ITP has similar long-term therapeutic response,but it has advantages of minimally invasiveness.

Artificial intelligence (AI) has developed rapidly in the twentieth century, and has substantialy changed the modern way of life.At the same time, AI has greatly contributed to the development of the pharmaceutical industry, playing a key role in precision medicine, intelligent diagnosis, computer-aided drug design, and clinical trial decision-making, and has also greatly developed itself through its integration with the pharmaceutical industry.This paper outlines the key issues in research, describes the key applications of AI in the health and pharmaceutical industries, and finally analyzes the opportunities and challenges of AI in the health pharmaceutical industry to provide reference for the development of AI in the health and pharmaceutical fields.

It is widely acknowledged that the liver is the most common organ for colorectal cancer metastasis, and radical resection is thought to be the only therapeutic method to cure colorectal cancer liver metastasis (CRLM). Unfortunately, only about 20% of all patients are eligible for surgical resection. In patients who cannot be treated with surgery, transcatheter arterial chemoembolization (TACE) has been widely used as the preferred therapeutic method by scholars at home and abroad. This article introduces the application basis, indications, contraindications, therapeutic effect, chemotherapeutic agents, and embolic agents of TACE in the treatment of CRLM, and points out that TACE is a palliative treatment regimen with a clear therapeutic effect, minimal invasion, and few side effects and can be used as the preferred therapeutic regimen for patients with unresectable CRLM.

Objective Admission hyperglycemia is thought to be related to poor neurological function and high mortality in patients with spontaneous intracerebral hemorrhage (sICH).However, it is not known whether preictal glycemic status affects functional outcome of sICH.The study is aimed to disclose the association between preictal glycemic status and neurological outcomes in patients with acute sICH.Methods Three hundred and thirty-two patients with sICH, admitted to our hospital from January 2011 to September 2013 (within 24 h of onset), were chosen in our study.Pre-stroke glycemic status, represented by hemoglobin A1c (HbA1c), was determined the next day after admission.Patients were categorized into four groups according to HbA1c values (＜6％, 6.1％-7％, 7.1％-8％ and ≥8％).The correlations of HbA1c in the four groups with different variables (NIHSS scores, hematoma volume, modified Rankin scale [mRS] scores) were analyzed using Spearman correlation test.Patients were also categorized into two groups according to hematoma volume (≤25 mL or ＞25 mL) or mRS scores (≤2 or ＞2).Logistic regression analyses were used to determine the relative independent risk factors for both hematoma volume and mRS scores.Results The hematoma volume, NIHSS scores, mRS scores, and number of patients with diabetes mellitus were significantly different among the four groups (P＜0.05).Blood glucose at admission and HbA1c level were significantly correlated with hematoma volume (r=0.085, P=0.027;r=0.164, P=0.014).Age and HbA1c level were significantly correlated with mRS scores (r=0.027, P=0.019;r=0.199, P=0.003).Conclusion HbA1C alone could serve as a better predictor of poor outcome after sICH than glucose at admission;HbA 1 C is the independent risk factor of poor prognosis for sICH.

The intention to treat (ITT) principle is widely applied in the randomized controlled trials (RCTs), which is based on the intention to treat a subject (i.e. the planned treatment regimen) rather than the actual treatment given. With the development and progress of clinical trials, ITT principle needs to be reinterpreted. In the standard definition of ITT principle, the intentional grouping of subjects does not specifically refer to randomization, but rather to planned treatment regimen. In non-randomized clinical trials, that subjects agree to be included in a certain treatment regimen is also a type of intention. ITT principles can be applied to evaluate the effectiveness of treatment regimens under patient/doctor determined intentionality in single-arm clinical trials and non-randomized RWS (real world study, RWS). In the practical application, the grouping strategy based on ITT principle should be considered comprehensively according to the research purpose.
