Objective To clarify diagnostic value of C-reactive protein (CRP) in the pathological types of acute appendicitis in children and the role of CRP as a surgical indication marker for appendicitis.Methods Two hundred and six patients who underwent appendectomies and had pathologically confirmed appendicitis were reviewed between January 2010 and February 2014,and they were divided into gangrenous appendicitis group(n =53) and non-gangrenous appendicitis group(n =153) by postoperative pathological type.The correlation between preoperative clinical factors and the actual histological severity,and identify surgical indication markers were assessed by multivariate analysis and ROC analysis.Results There were significant differences in white blood count(WBC),neutrophils percentage and CRP level between gangrenous appendicitis group and non-gangrenous appendicitis group(P ＜ 0.05).Multivariate analysis showed that the level of CRP should be a risk factor for judging gangrenous appendicitis.It showed that the role of CRP in judging gangrenous appendicitis was superior to the proportion of neutrophils and WBC in the ROC curve.The ROC curve showed that the area under the ROC curve for the CRP level,neutrophils percentage and WBC was 0.931,0.659 and 0.599 respectively,and the optimal cut off value of CRP for surgical indication for classifying cases was around 44.4 mg/L,and the sensitivity was 75.5 ％,specificity was 93.5 ％.Conclusion The level of CRP is useful in identifying the pathological types of acute appendicitis in children,and can be considered to be a surgical indication marker for acute appendicitis in children.

Objective DNA replication increases during tumor cells limitlessly proliferate. To develop a method that can early diagnose and routine screen out bladder cancer, but it does not impair patients by detecting cdc6 in exfoliate cell in urine of patients with bladder cancer. Methods 200 ml fresh urine of patients with bladder cancer or non bladder cancer who voided urine after morning was collected and centrifugated for urine sediment, then total RNA was extracted with TRIZOL reagent from it and detected the expression of cdc6 gene by RT PCR. Results 28 samples were positive and 2 samples were negative in 30samples of bladder cancer, positive rate was 93.3%. Positive rate was 16.7% in 30 samples of non bladder cancer. Compared with the sensitivity of urine cytology, that of cdc6 RT PCR increases markedly ( P

Objective To study the feasibility and care mode of remote fetal monitoring at primary hospital. Methods A questionnaire survey was administered to 71 hospitals of different levels in Jiangsu province.Question-naire content included human resources status of midwifery,the remote fetal monitoring system and its clinical applica-tion;anonymous questionnaire survey was conducted to 130 maternal women by random cluster sampling;investigation of remote fetal monitoring device type,operation mode,clinical usage and existing problems was done through the doc-ument retrieval of VIP and Wanfang data platform.Results In grade Ⅱhospital,obstetricians sufficient and insuffi-cient were 10 cases (24.39%),31 cases(75.6%),respectively,and in grade Ⅲ hospital were 8 cases (61.53%), 5 cases (38.46%),respectively,there was statistically significant difference between grade Ⅱ and grade Ⅲ hospital (χ2 =4.572,P <0.05);In grade Ⅱ and grade Ⅲ hospital midwives were obviously insufficient,but there was no sta-tistically significant difference between grade Ⅱ and grade Ⅲ hospital(χ2 =0.219,P >0.05).Different cultural lev-el,place of residence,occupation of maternal demand for the development of remote fetal monitoring were urgent and higher degree of acceptance,but the cognition was not comprehensive,college degree or above,technical personnel and urban pregnant women that their need for remote fetal monitoring were the most urgent.There were significant differ-ences(all P <0.01).The use of remote fetal monitoring equipment was mostly at tertiary hospital nationwide.3G net-work way to transfer data had short time and small scope.Conclusion The existing monitoring system and service mode can not meet the requirements of the implementation of remote fetal monitoring,medical personnel professional quality and maternal comprehensive quality are the main influencing factors.The primary hospitals should actively pro-mote the application of remote fetal monitoring,maternal health care services and health education should arouse the attention of the whole society.

Objective To investigate the clinical and pathological features of microscopic thymoma(MT).Methods The histopathological features of 12 cases of MT were observed by histopathologic and immunohistochemical methods.The pathological morphology,diagnosis,and differential diagnosis were discussed combined with literature.Results 6 cases of MT were accompanied by myasthenia gravis(MG) symptoms.Focal hyperplastic thymic epithelial islands were accompanied by large tracts of mature adipose tissue in 12 cases of MTs,and immunohistochemistry showed CK positive.Cyst formation was found in 5 cases,lymphoid hyperplasia in 7 cases,and vascular proliferation in 5 cases.Conclusions MG may be the clinical manifestation of MT.MT can occur in thymic cortex,medulla and cortex and medulla junction.Since the tumor is small and the lesions are multiple,it can not be found by X-ray or CT examination.Diagnosis depends on histopathological examination.Correct understanding of the clinical and pathological features of MT has guiding significance on the treatment and prognosis judgment of MT.Thymic resection was recommended for MG patients either with or without thymoma.

Objective To explore the bone mineral density (BMD) status and its influencing factors in schizophrenia patients in order to provide basis for risk assessment in psychiatric nursing.Methods A total of 1,139 hospitalized schizophrenia patients were recruited and assigned into the medication group (n=652) and the non-medication group (n=487) according to previous antipsychotic drug history.T-score and Z-score of BMD were determined using Sunlight Omnisense 7000S Bone Densitometry.Blood calcium,blood phosphorus and serum prolactin levels were measured using fasting blood of ulnar vein.Results Differences in age,BMD,milk intake,level of activity,level of smoking,history of fall,history of fracture,serum Ca2+ and PRL were statistically significant between two groups(P＜0.05);there were significant differences in BMD rank distributions among schizophrenia patients with different courses of disease and lengths of taking antipsychotics (P＜0.001);multiple linear regression showed that influencing factors of BMD with statistical significance were courses of disease,lengths of taking antipsychotics,serum Ca2+,serum PRL,milk intake,level of activity,and level of smoking.Conclusion The BMD was lower in the medication group than that in the non-medication group,and the development of osteoporosis was correlated to various factors.Clinical nurses should master high-risk factors thoroughly and adopt intervention measures in a timely manner.

Objective To study the expression of MCM5 gene in urine exfoliate cell and bladder cancer tissue in order to research the diagnosis and difference.

This paper studied the diagnosis and embryology of 20 cases lacking one pulmonary artery out of 2040 patients operated for tetralogy of Fallot. History of severe cyanosis syncope and hemoptysis was usually present in the majority of these patients. The important diagnosis characteristic was asymmetry of plumonary vascularity on X-ray film and the decrease of pulmonary cascular markings on the side without plumonary artery. A right ventricular cardiogram can confirm the absence of one pulmonary artery or the blind-end like change.
