Chinese Journal of Primary Medicine and Pharmacy 2016;23(20):3053-3056,3057
Objective To assess the clinical value of 18F -FDG PET/CT in the diagnosis of primary, suspected recurrent and metastatic cervical cancer.Methods The results of 67 women who were suspected suffering from cervical cancer had undergone Color dopplar ultrasound,HPV,TCT,some of them do CT,MRI and SCC -Ag examination from April 2013 to April 2015 were retrospectively analyzed.Their 18F -FDG PET/CT images with the other test results were compared.The presence or absence of tumor was confirmed by histopathology.Results In the 67 patients,22 cases were finally diagnosed as primary cervical tumors,and 22 cases of recurrent and metastatic cervical tumors.In all the patients with cervical cancer,18F -FDG PET/CT found a total of 41 cases,which had contributed to the diagnosis in 94.0%,But 3 cases had not been found.For the detection of primary cervical tumors, 18F -FDG PET/CT was diagnostically wrong in 4.2%,For the detection of recurrent and metastatic cervical tumors, 18F -FDG PET/CT was diagnostically wrong in 7.0%,and 2 cervical adenocarcinoma patients were not diagnosed by 18F -FDG PET/CT.Conclusion The study showed a significantly higher sensitivity of 18F -FDG PET/CT for the detection of primary,recurrent and metastatic cervical cancer than the other auxiliary examination.18F -FDG PET/CT for the diagnosis of cervical cancer can be worth popularization.

Chinese Journal of Laboratory Medicine 2000;0(06):-
Objective To study the Ile796Val polymorphism in human SCAP gene in Hubei area, and analyze its correlation with coronary heart disease (CHP) and hypertension and the relationship between polymorphism and lipid metabolism. Methods Using PCR RFLP, we detected genotypes of Ile796Val polymorphism in human SCAP gene. Results The allele A frequencies of Ile796Val in human SCAP gene for controls, CHD patients and the hypertension patients were 0.32, 0.45 and 0.42 respectively. The allele G frequencies were 0 68, 0.55 and 0.58 respectively. There were significant differences in frequencies of genotype and alleles between controls and hypertension group. And there was significant difference in the level of TC, LDL C and ApoB. In CHD group, there was significant difference in the TC level between different genotypes. In hypertension patients, although a difference was noted in genotype, there was no significant difference in allele frequencies and lipid level exceps a significant difference in the levels of TC, LDL C and ApoB in hypertension patients. Conclusion Ile796Val polymorphism in human SCAP gene may be a great agent to cause disorder in the lipid level of blood and lipid metabolism of tissue. It is of great significance in disorder in lipid metabolism of inter cellular and genetic investigation of hyperlipidemia.

Neoplastic stem cells (NSCs)are the source of tumor occurrence and development,and its special microenvironment is involved in tumor drug resistance,recurrence and metastasis by regulating NSCs or changing itself. Eradicating NSCs and interfering the special microenvironment may be the new therapeutic strategies for cancer.

Objective To evaluate the safety of nasogastric tube feeding and nasojejunal tube feeding in early enteral nutrition treatment of acute pancreatitis.Methods Using key words,subject headings,and citation tracing,we searched literatures reporting randomised controlled trials on early enteral nutrition treatment of acute pancreatitis through nasojejunal tube and nasogastric tube in the following databases:PubMed,Embase,Cochrane library,Wanfang,China National Knowledge Infrastructure (CNKI),and VIP published since the founding of the databases up to 2016.Meta-analysis was performed with the selected literature.Results Seven randomised controlled trials with 367 patients were included.Meta-analysis showed that the nasogastric tube group was not inferior to the nasojejunal tube group in the incidence of recurrent abdominal pain,gastrointestinal adverse reaction,the total length of hospital stay,and mortality.Conclusion Enteral nutrition via nasogastric tube is safe and well tolerated,may be a safe approach of nutrition treatment for acute pancreatitis.

Sepsis is a high-risk factor for the death of critical patients. High density lipoprotein (HDL) are the major protective serum proteins, and the serum levels of HDL are closely related to the severity of sepsis. The anti-inflammatory and anti-oxidation properties of HDL, may be able to play an important role in the innate immune response. Thereby it may reduce the damage of septic shock and multiple organ dysfunction syndrome (MODS) in animals or human beings, and improve the prognosis. In order to unveil the metabolism of HDL in septic patients and its effects on both progression and prognosis of sepsis, this review not only focuses on the composition and structure of HDL, but also analyzes its pivotal role in inflammatory immune response and anti-oxidation.

Objective To explore the effects of oxidative stress in the pathogenesis of lung injury and observe the influence of N-acetylcysteine (NAC). Methods The lung histopathology was observed by light microscope. The level of 8-iso-prostaglandin F2?lpha (8-iso-PGF2?) in blood plasm were measured by ELISA. The difference of 8-iso-PGF2? in blood plasm in air group, different dose NAC groups between hyperoxia-model and the air group was compared. Results In hyperoxia-model group, the inequality of size of lung alveoli, hemorrhage and inflammatory cell infiltration in lung alveoli were observed on the 3rd and 7th day. The alveolar septum was thick in the hyperoxic-damaged lungs on the 14th and the 21st day. In hyperoxia+high-dose NAC group, very small amounts of red blood cells leaked out into alveoli on the 3rd and 7th day and alveolar septum had no thickening obviously on the 14th day and the 21st day. The level of 8-iso-PGF2? in blood plasm in hyperoxia-model group [(28.33?5.57) pg/ml, (51.21?15.01) pg/ml, (84.54?14.85) pg/ml and (43.14?11.37) pg/ml at every time points] was higher than that of the air group and hyperoxia+high-dose NAC group(P

Evidence based medicine is medicine based on evidence and the application of evidence based medicine to laboratory medicine is evidence based laboratory medicine. The major enforcement strategies of evidence based laboratory medicine include: discovering problems and bringing them forward; seeking valuable evidence from the laboratory or relevant literature; making experimental or methodological assessments; application in the practice of clinical laboratory; and evaluating the results of the practice. Evidence based medicine and evidence based laboratory medicine are of great significance to the advancement of laboratory medicine and clinical work.

Objective To evaluate the safety and efficacy of OUR Rotating Gamma System in neurosurgical clinical application. Methods Based on the results of animal experiments, 2381 patients with intracranial disease were treated using OUR Rotating Gamma System in Aohai Gamma Knife Center of Navy General Hospital of PLA betwean December 1996 and November 2002. There were 1288 males and 1093 females and their age ranged from 3 to 84 years (mean 45.8 years). 1020 patients had benign intracranial tumors, and of them 446 suffered from pituitary tumors, 254 meningioma, 148 craniopharyngioma and 103 vestibular schwannomas. Malignant tumors were diagnosed in 796 patients, among them glioma was found in 360 and metastasis in 360. 374 patients had cerebral arteriovenous malformations (AVMs) and 191 functional neurological disorders. Treatment technique of Gamma Knife Stereotactic Radiosurgery, dose prescription and precise orientation performed in intracranial tumor or foci were analyzed, and the preliminary outcome of treatment was evaluated in this study. In addition, the management of the possible complication and adverse reaction was studied. Results Gamma Knife Stereotactic Radiosurgery alone, or combined with other treatment procedures, could cure some of selected patients with benign brain lesions including pituitary neoplasms, meningioma, vestibular schwannomas, AVMs, and craniopharyngioma etc. And this treatment was also beneficial to some patients with malignant tumors. The incidence of radiation edema was 0.75%. Conclusions The clinical results suggest that Gamma Knife Stereotactic Radiosurgery is a very effective, accurate and relatively safe neurosurgical tool used either as a primary or adjuvant procedure for treatment of intracranical pathologic processes. However, it might lead to some severe or fatal complications if used inappropriately. Thus, optimal result would not be obtained unless a careful and precise Gamma treatment based on the operative rules and the effective management for postoperative complications are well planned.
