Pancreatic cancer is characterized by high invasiveness,high malignancy and poor prognosis. Therefore,it is urgent to find biomarkers for early diagnosis and to develop targeting drugs for treatment of pancreatic cancer. MicroRNAs (miRNAs)are single-stranded,non-coding small RNA molecules with a length of 18-25 nucleotides and are highly expressed in pancreatic cancer. MiRNAs play important roles in cell proliferation,differentiation,apoptosis,invasion and metastasis,and are associated with adverse prognosis and resistance to chemotherapy in pancreatic cancer. As a new target for diagnosis and treatment of pancreatic cancer,miRNA-21 has become the hot spot of clinical research. This article reviewed the advances in studies on miRNA-21 in the pathogenesis,diagnosis and treatment of pancreatic cancer.

Objective To assess the value of magnetic source imaging (MSI) in localizing the linguistic center of auditory function of epileptic patients before operation. Methods Epileptic focus and the linguistic center of auditory function in 24 patients were localized with MSI before operation. And the relationship between epileptic focus and auditory language area was observed. Results The linguistic center of auditory function was localized in left temporal lobe in 14 patients, in right temporal lobe in 5 patients and in bilaterial temporal lobe in 5 patients. Epileptic focus was localized in left temporal lobe in 14 patients, in left temporal lobe and left parietal lobe in 1 patient, in right temporal lobe in 4 patients, in right temporal lobe and parietal lobe in 1 patient, in left frontal lobe and left temporal lobe in 1 patient, in right frontal lobe, right temporal lobe and parietal lobe in 1 patient, and in bilaterial temporal lobe in 2 patients. Epileptic focus was superimposed with the linguistic center of auditory function in 10 patients, while was not superimposed with the linguistic center of auditory function in 10 patients. The epileptic focus was localized in front of the linguistic center of auditory function in 3 patients, in behind of the linguistic center of auditory function in 1 patient. The lesion of the patient suffered from dysembryoplastic neuroepithelial tumor was not excised completely because the epileptic focus was superimposed with the linguistic center of auditory function, and the patient appeared language functional disturbance after operation in short period, remaining auditory hallucination occasionally after operation. Conclusion Epileptic focus and the linguistic center of auditory function can be localized accurately and the relationship between them can be observed clearly with MSI. MSI is useful to reduce the occurrence of language disturbance after operation.

Objective To observe the changes of magnetoencephalography (MEG) during stretching and flexing forefinger in one hemiplegic patient before and after rehabilitation training.MethodsThe cerebral electromagnetic wave of one hemiplegic patient during stretching and flexing both forefingers was recorded by MEG and superposed with magnetic resonance imaging (MRI) to form magnetic source imaging (MSI). The changes of MEG before and after rehabilitation training were analyzed.ResultsThere was no movement evoking magnetic fields in right hemisphere motor cortex at two MSI detections, but detected in left hemisphere motor cortex. The latent period of the first and the second detection was -34.2 ms and -61.7 ms respectively. The exiting motor cortex was located in precentral gyrus. The exiting motor cortex at the second detection was located more front medial and low than at the first detection. The volume of the exiting motor cortex (9569.6 m3) at the second detection was more larger than the first detection (2309.7 m3). There was no movement evoking somatosensory magnetic fields in right hemisphere motor cortex at first MSI detection, but found at the second detection, the latent period was 91.1 ms, and the exiting cortex was located in postcentral gyrus.ConclusionThe cortex somatosensory function of patient with stroke recovers early than the motor function and the uninjured hemisphere function can improve obviously after rehabilitation training.

Imaging examinations such as CT,MRI and ultrasonography are of great importance for the diagnosis of digestive system neoplasms. However,some digestive system neoplasms are difficult to be detected at early stage and make qualitative diagnosis by conventional imaging techniques because of their unique clinical characteristics. Compared with conventional imaging techniques,endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA)can not only detect the early lesions,but also make accurate qualitative diagnosis. The development and improvement of EUS-FNA greatly improve the diagnostic level of digestive system neoplasms. In this paper,the diagnostic value of EUS-FNA in digestive system neoplasms was reviewed.

Objective:To observe the effect of intravenous anesthesia with target-controlled infusion (TCI) of remifentanil combined with propofol on hemodynamics in middle-aged and elderly patients with intracranial aneurysm clipping. Methods:Totally 40 cases of middle-aged and elderly patients undergoing intracranial aneurysm clipping were divided into combined anesthesia group and propofol group according to the random number table. The combined anesthesia group was treated with remifentanil combined with propofol target intravenous anesthesia, and propofol group was treated with propofol intravenous hypotension. The changes of mean arterial pressure(MAP),heart rate(HR),cardiac output(CO) and heart index(CI) before the induction of anesthesia (T1), tracheal intubation (T2), before aneurysm clipping(T3), after aneurysm clipping(T4) and extubation (T5) were observed. The anesthesia maintenance time, extubation time, postoperative wake-up time and adverse reactions were compared. Results:There were no significant differences in MAP and HR between the groups(P > 0.05), the levels of MAP,HR,CO and CI at T2,T3and T4were significantly lower than those at T1,and CO and CI were significantly lower in combined group than those in propofol group(P < 0.05). Conclusion:TCI remifentanil combined with propofol can maintain hemodynamic stability, shorten extubation time and wake-up time, and reduce the incidence of adverse reactions in the patients with intracranial aneurysm clipping.
