Objective: To investigate the effect of three different goals of blood glucose control by insulin therapy on protein metabolism in the patients with critically cerebral disease.Methods: We performed a prospective,randomized,controlled study.A total of 122 patients with critically cerebral disease were randomly divided into three groups according to the target glucose-control levels:Group A: 4.4-6.1 mmol/L(n=41),Group B: 6.1-8.3 mmol/L(n=42),and Group C: 10-11.1 mmol/L(n=39).The state of protein metabolism and ratio of hypoglycemia of three groups were compared.Results: The indicators of nitrogen balance,prealbumin and transferrin in group A and group B were significantly better than that in group C(P<0.05),but the ratio of hypoglycemia in group A was significantly higher than those in group B and group C(P<0.05).Conclusion: Maintaining the blood glucose level ≤8.3 mmol/L might improve the nutrition status in the patients with critically cerebral disease by decreasing catabolism and promoting synthesis of protein.

Objective To investigate the expression of sLc22A1 8,an impfinted tumor suppressor gene,in breast cancer and explore the relationship between expression of SLC22A18 and the pathogenesis of breast cancer. Methods Real-time quantitative reverse transcriptase-polymerase chain reaction was applied on 46 cases of infiltrating duetal breast carcinoma(IDC),46 csges of corresponding adjacent noncancerous tissues and 20 benign breast tissues in order to detect mRNA expression of SLC22A18 gene.Protein expression was detected by immunohistochemistry.Statistical analysis was carried out to analyse the correlation between SLC22A18 gene expression and various elinical parameters in these breast cancer patients. Results SLC22A18 mRNA expression in 46 IDC tissues Was lower than that in all corresponding adjacent non-cancerous tissues(Z=-4.900,P＜0.01).SLC22A18 mRNA expression was lower in breast cancer eases,when compared with that in benign cases(Z=-3.182,P＜0.01).SLIC22A18 mRNA expression in 40 IDCs Was lower than that in 6 dutal carcinoma in situ(part of IDC)(Z=-2.022,P＜0.05).There was a decreased or completely diminished SLC22A18 protein expression in breast cancer.A significant difference of SLC22A18 protein expression was also observed in IDC and benign groups(P＜0.05).Neither mRNA nor protein expression of SLC22A18 gene correlated with clinieopathologic parameters such as age of patients,size of tumor,ehnical stage,pathologic subtype,histologlc grade or lymph node metastasis(P＞0.05).Condusion Decreased expression of SLC22A18 gene may play an important role in the carcinogenesis of IDC.

Objective To summarize the experience on diagnosis and treatment of primary hyperparathyroidism(PHPT).Methods Clinical data of 91 PHPT patients treated in Beijing Jishuitan Hospital from November 1992 to December 2008 were analyzed retrospectively.Results Among 91 PHPT cases,88 were diagnosed as parathyroid adenoma(96.7%),3 were diagnosed as parathyroid carcinoma (3.3%).Serum calcium and PTH levels increased in all cases.Main clinical manifestations were osteodynia and kidney stones.The accuracy rate of preoperative B-ultrasound.CT and ECT~(99m)Tc-MIBI on location was 83.5%(76/91),60.9%(14/23)and 98.6%(69/70)respectively.Parathyroidectomy was performed in all but one cases,in which parathyroid carcinoma was managed by ipsilateral hemithyroidectomy and modified neck dissection.The cure rate of primary operation was 97.8%(89/91).Ninety cases were followed-up from 8 months to 14 years postoperatively,87 cases with parathyroid adenoma achieved complete remission,2 with parathyroid carcinoma suffered from tumor recurrence and 1 died.Conclusion Patients with chronic bone diseases,repeatedly recurrent nephrolithiasis,peptic ulcer disease should be a suspect of PHPT.The routine examinations of serum calcium and phosphorus are to be conducted.UItrasonography and ECT~(99m)Tc-MIBI should be considered as the methods of first choice for preoperative localization.

Objective To analyse and explore the situation and causes of misdiagnosed primary hyperparathyroidism(PHPT),so as to develop some strategies for preventing and reducing misdiagnosis.Methods Clinical data of 94 misdiagnosed patients with PHPT treated in Beijing Jishuitan Hospital from November 1992 to April 2009 were collected and analyzed retrospectively.Results All cases were confirmed by operation and pathology.Among the 94 cases,90 cases were of parathyroid adenoma,and 4 cases of parathyroid carcinoma.The rate of misdiagnosis was 97.9%(94/96).The length of time of misdiagnosis was 2 months to 20 years;

AIM:To study the mRNA expression and methylation status of imprinted gene SLC22A18 in infiltrating ductal carcinomas(IDCs),and the correlation between methylation status and clinical characteristics in IDCs.METHODS:The methylation status at the promoter regions of SLC22A18 gene was examined by methylation-specific polymerase chain reaction(MSP)in the specimens of IDC from 40 patients.The mRNA expression of SLC22A18 gene was detected by real-time reverse quantitative transcriptase polymerase chain reaction(real-time RT-PCR)in 40 specimens of IDC and the cell line MDA-MB-231.The cell line MDA-MB-231 was treated with 5-aza-2'-deoxycytidine(5'-aza-dc)and trichostatin A(TSA),then MSP and rea1-time RT-PCR were used to detect the methylation status and mRNA expression levels of SLC22A18 gene.RESULTS:SLC22A18 mRNA expression in 40 IDC tissues was lower than that in al1 corresponding adjacent non-cancerous tissues(P

RNA has received m ore attention in the field of forensic m edicine and the developm ent of the new biological m arkers based on RNA show s great significance in the analysis of com plex cases. circular RNA (circRNA ) is a kind of non-coding RNA w hich is w idely reported recently. A lthough the regulatory m echanism s of generation and expression are not fully clear, the existing research indicates that circRNA has im portant biological functions. C ircRNA has a cell-type-specific expression w ith great stability and a high expression level, w hich m akes it m eaningful in forensic applications potentially. In this paper, the research progress, the generation and regulation of circRNA as w ell as its biological characteristics and functions are sum m arized, w hich w ill provide references for related studies and foren-sic applications.

Objective To analyze the cases of anaphylactic death cases and explore the standards of judi-cial expertise of anaphylactic death for providing evidence for judicial expertise. Methods Fifty-nine cas-es death due to allergic reaction in Shanghai were collected. And details of medical history, clinical manifestation of anaphylactic reaction and postm ortem exam ination findings were review ed for all cases. Results In the 59 cases, there were 58 cases died from drug allergy, including 77.6% of them were an-tibiotics. The rates of treating in standard hospital and illegal clinic were 37.3% and 61.0%, respectively. The allergic sym ptom s were dyspnea and facial cyanosis. The time from contacting allergens to death ranged from 1 m in to 3 d. The concentration of total serum IgE ranged from 50 to 576.92 IU/m L . The results of clinical manifestation and pathological anatomy had obviously changes. Conclusion B ased on the exclusion of all other cause of death and synthetically analysis of details of cases, medical history, clinical manifestation and anatomy, the conclusion of anaphylactic death can reached. The details of cas-es including clinical history, exposure to allergens, and clinical manifestation play an im portant role in diagnosis of anaphylactic death.

Six cases of suicidal sedative-soporific drug poisoning is reported.The main clinical features were coma,respiratory depression,hypotension,disappearance of reflexes and peripherel circulatory failure.Thepathological fingdings were as follows:pulmonary congestion and edema;fatty degeneration of the liver;degeneration of the epithalial cells of the proximal convoluted tubules and cerebral edema.The severityof the pathological changes depend upon the duration between the drug administration and the time of deathThe longer the course,the more prominent the changes.The fatality rate related with the dose of drugadministration,the underlying deseases and the complications.
