Xiang XUE ; Shinan NIE

Journal of Medical Postgraduates.2014;(4):439-443.

Intestinal trefoil factor (ITF or TFF3) is a member of trefoil factor family which is most studied , mainly in the in-testinal tract .TFF3 plays an important role in gastrointestinal mucosal protection and epithelial repair .Action mechanism includes in-teraction with mucin, migration, anti-apoptosis, angiogenesis, immune regulation, interaction with its receptor, etc.Recombinant TFF3 has been approved as a national drug and its therapeutic indications for repair mucosa , prevention and treatment of gastrointesti-nal ulcers and inflammation .Furthermore, the classic TFF3 receptor and signaling pathway is highly valuable to make TFF 3 become an effective treatment for gastrointestinal injury disease .

Research progress of the relationship between miRNAs and pancreatic carcinoma

Yingxia HU ; Hairong ZHANG

Journal of Medical Postgraduates.2014;(4):435-438.

MiRNA is a small non-coding single stranded RNA(ssRNA)which is made up by 21~23 nucleotide.This ssRNA has a double effect as tumor suppressor genes and oncogenes , and plays an important role in cell proliferation , differentiation and apop-tosis.Pancreatic carcinoma is a highly malignant tumor with poor prognosis and high mortality rate , and the early diagnosis is difficult . In the last decades , growing studies highlighted the interactions between miRNAs and pancreatic carcinoma .This review provides a re-search overview between miRNAs and pancreatic carcinoma .Meanwhile , the significance of Expression Profile in pancreatic carcinoma′s diagnosis ,treatment and prognosis is also discussed .

Journal of Medical Postgraduates.2014;(4):408-410.

The hospital grade assessment is an effective approach to measure the comprehensive strength and the overall level of a hospital, and it is also an effective carrier which can promote the standardized management , improve the quality of connotation and accelerate the development of the hospital .This article aims to expound the effective and concrete methods for preparation in the hospi -tal grade assessment by introducing the practice and experience of Jinling Hospital in grade assessement .It also points out that:defi-ning the purpose of the assessment is the fundation , having a thorough grasp of the assessment criteria is the basis , having a compre-hensive knowledge of the hospital is the premise , establishing and implementing the plan strictly is the crux .All these might be helpful to promote the hospital grade assessment .

Establishing a harmonious doctor-patient relationship based on common values

Peng HAN ; Shuqiang XU

Journal of Medical Postgraduates.2014;(4):405-407.

Doctor-patient relationship is a special relationship between people in special circumstances during a special peri -od, which is directly related to the harmony and stability of society as well as people's quality of life.Values are the fundamental views of people, including the understanding of the nature , composition and standards of values .Doctors and patients are consistent in goals , interests and ideals , having the same objectives to overcome diseases , promote health , and prolong lives .They are essentially unified in values.However, there are some inharmonious phenomena in the relationship between doctors and patients .Efforts should be made to improve the present doctor-patient relationship by the whole society besides doctors and patients , aiming to establish a harmonious doctor-patient relationship of mutual respect , mutual trust , mutual tolerance and mutual cooperation on the basis of common values .

The role of fiberoptic bronchoscopy in diagnosis and treatment of mycoplasma pneumoniae pneumonia associated with atelectasis in children

Lei LIANG ; Zeyu YANG ; Yating WANG ; Yu WANG

Journal of Medical Postgraduates.2014;(4):401-404.

Objective Mycoplasma pneumoniae is one of the main pathogens of community-acquired pneumonia in children and teenagers , which may cause mycoplasma pneumoniae pneumonia ( MPP) .Atelectasis is one of the most common manifestations of MPP.The aim of the article was to evaluate the diagnostic and therapeutic value of fiberoptic bronchoscopy ( FB) in children with MPP associated with atelectasis . Methods Retrospective analysis were made on clinical data and FB records of 99 cases of hospitalized children with MPP associated with atelectasis from August 2010 to December 2012 . Results The positive rate of MP-DNA was 92.9%(92/99) in bronchoalveolar lavage fluid (BALF), and the positive rate of MP-Ab-IgM in serum was 68.7%(68/99).All pa-tients showed obviously bronchial mucosa congestive edema during FB examination .The results are as follows:bronchial phlegm bloc-king in 31 cases (31.3%), lumen inflammatory stenosis in 22 cases (22.2%),mucosal ulcer change in 7 cases(7.1%) and mucous nodular change in 3 cases (3.0%).4 weeks after being treated with bronchoalveolar lavage (BAL), only 3 cases remained in atelec-tasis, the partial and complete re-expansion rate reaching 96.5%(82 of 85). Conclusion The positive rate of BALF MP-DNA de-tection technology for the diagnosis of MP infection is higher than that of serum MP-Ab-IgM examination .Early interventional therapy by FB can shorten the course of disease and promote the lung re-expansion in children with MPP associated with atelectasis .

Osteogenic and adipogenic induction of follicle stem cells in rats

Zhiqiang ZHANG ; Yujie WANG ; Jia LI

Journal of Medical Postgraduates.2014;(4):340-343.

Objective Hair follicle stem cells (HFSCs) can be cultured in vti ro to differentiate into chondrocytes, osteoblasts and adipocytes .The aim of the article was to investigate the culture method of HFSCs and their adipogenic and osteogenic differentiation potentials. Methods Microdissection and two-step enzyme digestion were applied to obtain HFSCs , and HFSCs are purified by differ-ential adhesion method.The cells were cultured in keratinocyte serum-free medium obtaining 10% fetal bovine serum.Flow cytometry was used to detect CD34、β1-integrin and CK15.The third-generation HFSCs were cultured by osteogenic inductor and adipogenic induc-tor respectively . Results Cultured HFSCs were homogeneous in shape , bearing the property of great refraction and typical cobble-stone-morph.By flow cytometry, the expression rates of CD34,β1-integrin and CK15 were 59.6%, 97.0%and 61.1%.Stem cells were in good growing condition from the third-generation cell growth curve.21 days after being induced by osteogenic inductor, calcified nodules appeared after alizarin red staining, while 14 days after being induced by adipogenic inductor, intracellular lipid droplets could be observed after oil red O staining. Conclusion Cultured HFSCs are chaterized by strong growth capacity and multiple differentiation potential .

Fang YANG ; Ling LIU ; Qian LI ; Jiafei DAI ; Maowei CHENG ; Li KONG ; Shenning ZHANG ; Guanghui CHEN

Journal of Medical Postgraduates.2011;24(5):495-498. doi:10.3969/j.issn.1008-8199.2011.05.011

Objective Benign childhood epilepsy with centrotemporal spikes (BECT) is the most common partial epilepsy syndrome in children, and responds well to carbamazepine (CBZ), oxcarbazepine (OXC), and valproic acid (VPA). The aim of this study is to investigate the therapeutic effect of OXC on BECT. Methods We retrospectively discussed a case of partial epilepsy in a 6-year-old boy with no abnormality on neuroradiologic examination. Results The patient′s seizures were easily controlled by administration of OXC, but electroencephalography (EEG) identified deterioration of the EEG features following the introduction of OXC monotherapy. Then OXC was gradually decreased in dose and substituted with VPA. When VPA was increased to the dose of 0.5g/d, the boy had no more seizures and exhibited normal EEG in the conscious state. Conclusion OXC may induce new types of seizure and aggravate EEG features although it is considered to be the first-line anti-epileptic drug (AED) and much better tolerated than either phenytoin or CBZ.

Livin and Urological Malignancy, related research and progress

Pengcheng LI ; Bo GE

Journal of Medical Postgraduates.2014;(7):772-776.

Oncogenesis is a sophisticated process which is polygenic , multi-stage,and multi-step.Livin as an apoptosis inhibi-ting factor , is one of the members of apoptosis inhibiting factor family , it expresses highly in many tumor tissues , and is closely related to the occurrence and development of urological tumor .Tumor growth can be inhibited by interfering the expression of Livin in tumor tis-sue,which will reduce the resistance to apoptosis and increase the rate of cell apoptosis .In recent years , more and more attention was paid to the studies of Livin on gene targeting therapy .Further research of Livin might provide new ideas for the early diagnosis , clinical treatment and evaluation of prognosis of tumor .
