一個出彩的文題,讓SCI論文更能博得眾人的眼球

文題是一篇論文最重要的、濃縮的資訊點, 是讀者最先直接看到的資訊。 一個好的文題, 並不一定要出彩, 但是一定要真實恰當地反映本文的研究內容或者結論。

SCI文題的基本要求一般包括以下幾點:

(1)字數要求:一般不超過100個字元, 最好在20個單詞以內;

(2)反映文章的特色, 例如多中心、隨機對照、長期隨訪、特殊人群, 需要在文題中體現;

(3)應包含文章中的關鍵字, 能夠真實地反映文章中的內容;(4) 通過標題應該可以推測到基本的實驗及結果。

我們來看一一下SCI醫學科研論文助手微信平臺中的科研助手(找SCI醫刊全文)上能檢索到的已經發表的文獻的文題。

例1:

文題:IntraoperativeBlood Loss Independently Predicts Survival and Resection of Colorectal Recurrence after Cancer Liver Metastasis

●文題的大意是術中失血是直結腸癌肝轉移手術切除後生存與復發的獨立預測因素, 我們來分析一下這個文題包含的資訊:

●這個文題非常直白地反映了論文的結論:

●從文題完全可以聯想到本文研究的基本內容,

文章應該會研究一些患者的基本臨床參數與治療預後之間的關係, 然後從眾多的參數中找出與預後相關的因數, 再從因數中找到獨立相關因數:

●而術中失血可能是以往未曾被確認的獨立相關因數, 也可能在以往研究中, 在其他的癌症中被確認過, 但是沒有在直結腸癌肝轉移這類患者中被確認;

●然後預後應該會有生存分析, 相關因數確認應該會用到COX回歸;

●此類文章一般都是回顧分析研究。

下面我們再來看看這篇文章的摘要, 來驗證一下是否如我們分析的一樣。

BACKGROUND: Although numerous prognostic factorshave been reported for colorectal cancer liver metastasis (CRLM) , few studies have reported intraoperative blood loss (IBL)effectson clinical outcome after CRLM resection.③ METHODS: Weretrospectively evaluated the clinical and histopathological characteristics of139 patients who underwent liver resection for CRLM.② , ⑤ The IBL cutoff volume was calculated using receiver operatingcharacteristic curves.Overall survival( OS )and recurrence free survival( RFS)were assessed using the Kaplan-Meier and Cox regression methods.④, * RESULTS:All patients underwent curative resection.The medianfollow up period was25.0 months (range,2.1-88.8).Body mass index (BMI) and CRLMnumber and tumor size were associated with increased IBL.BMI(P=0.01;95% CI=1.3-8.5) and IBL (P<0.01; 95% CI= 1.6- 12.5 )were independent OSOspredictors.Five factors , including IBL(P=0.02; 95% CI=1.1-4.1), were significantly related to RFS viamultivariate Cox regression analysis.In addition,OSOs and RFS significantlydecreased with increasing IBL volumes.The 5-year OSOs of patients with IBL≦250,250-500,and >500mL were 71%, 33%, and 0%, respectively (P<0.01).RFS ofpatients within three IBL volumes at the end of the first year were 67%, 38%, and 18%, respectively(P<0.01).CONCLUSIONS: IBL during CRLM resection is an independent predictorof long term survival and tumor recurrence , and itsprognostic value was confirmed by a dose-response relationship.①

* 此處有誤, Cox回歸用於確認相關因數, 並非用於生存分析。

由此我們可以看到, 這個文題包含的資訊與文章的內容是非常契合的。

摘要中的①, ②, ③..對應文題所包含的資訊。
