Objective To study the role of genomic imprinting of IGF2 gene in the development of lung cancer.Methods The IGF2 genomic imprinting was studied among 32 patients with lung cancer and the normal lung tissues by using PCR and RFLP.Results Twelve out of the 32 patients were informative(37.5),among whom 10 exhibited biallelic expression,i.e.,LOI(83.3).The matched normal tissues from 4 of these 10 patients also showed weak biallelic expression of IGF2.Conclusion The findings indicate that the loss of IGF2 imprinting is involved in the development of lung cancer.
2.Role of TRAIL in the treatment of prostate cancer: An update.
National Journal of Andrology 2015;21(10):941-944
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF super family found in recent years, which widely exists in the body tissues and participates in the immune regulation, immune stability, and immune surveillance of the human body. The TRAIL receptor is expressed in the surface of a variety of cells. Recent studies show that TRAIL induces the apoptosis of tumor cells and has no significant toxic effect on normal cells. Its anti-tumor activity and safety have been widely recognized. The development of prostate cancer is regulated by the mechanisms of cell apoptosis. TRAIL can induce the apoptosis of prostate cancer cells, and therefore has a great application value in the treatment of prostate cancer.

Objective To investigate the correlation between helicobacter pylori infection and pathological characteristics of gastric mucosal in the elderly.Methods Retrospective analysis was conducted in 278 patients with benign upper gastrointestinal disease from January 2014 to June 2014.The patients were examined by endoscopy and 13C-UBT,and divided into elderly group (aged 60 years and over,n=111) and non-elderly group (aged<60 years,n=167).The relationships between Hp infection and pathological changes in gastric mucosal tissue (severe chronic inflammation,neutrophil infiltration,lymph follicles,gastric gland atrophy,intestinal metaplasia) were analyzed.Results There was no significant difference in helicobacter pylori infection rate between the elderly group and non-elderly group [27.0% (30/111) vs.36.5% (61/167),P>0.05].The rate of gastric gland atrophy was higher in elderly group than in non-elderly group [13.5% (15/111) vs.6.0% (10/167),P=0.028].The rates of severe chronic inflammation,neutrophil infiltration,lymph follicles,gland atrophy and intestinal metaplasia were 73.6%,70.3%,14.3%,18.7%,29.7% in patients with helicobacter pylori infection,which were higher than those in patients without helicobacter pylori infection (19.8%,3.2%,0.5%,4.3%,8.6%,respectively,all P=0.000).Removing the factor of Hp infection,the rates of glands atrophy and intestinal metaplasia were higher in elderly group than in non-elderly group (8.6% vs.0.9%,43.3% vs.23.0%,P=0.013 and 0.045).Conclusions Helicobacter pylori infection correlates with severe chronic gastric mucosal inflammation,neutrophil infiltration,lymph follicles formation.Gland atrophy and intestinal metaplasia are related to the Hp infection,and age is also their influencing factor.

Objective To evaluate the efficacy of hydromorphone for patient-controlled intravenous analgesia (PCIA) after hip replacement in elderly patients.Methods Seventy patients, aged 65-75 yr, weighing 40-70 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , undergoing elective unilateral hip replacement, were randomly divided into either analgesia with hydromorphone group (group H, n =35) or analgesia with fentanyl group (group F, n=35).After a loading dose of 20 μg/kg of hydromorphone was injected at the beginning of skin closure, a PCA pump was connected, and the PCIA solution contained hydromorphone 0.25 mg/kg and tropisetron 10 mg in 120 ml of normal saline in group H.After a loading dose of 1 μg/kg of hydromorphone was injected at the beginning of skin closure, a PCA pump was connected, and the PCIA solution contained fentanyl 25 μg/kg and tropisetron 10 mg in 120 ml of normal saline in group F.The PCA pump was set up with a 0.5 ml bolus dose, a 15 min lockout interval and the background infusion at a rate of 2 ml/h in both groups.Tramadol 0.5 mg/kg was injects intravenously as rescue analgesic, and visual analogue scale score was maintained ≤ 3.The Ramsay sedation score,the number of attempts and the number of tramadol administration were recorded at 24 and 48 h after operation.The adverse effects within 48 h after operation and patient's satisfaction with analgesia were recorded.Results There was no significant difference in the Ramsay sedation score, the number of attempts and the number of Tramadol administration between H and F groups.Compared with group F, the incidence of adverse effects such as postoperative nausea, vomiting, respiratory depression, drowsiness, urinary retention, was significantly decreased, and the level of satisfaction with analgesia was increased in group H.Conclusion Hydromorphone provides accurate efficacy for PCIA after hip replacement in elderly patients, with fewer adverse effects and higher level of patient' s satisfaction.

Objective To investigate changes of serum proteins and related enzymes in patients with schizophrenia and its relationship to metabolic syndrome.Methods Five hundred and three inpatients with schizophrenia and 60 healthy volunteer were selected in this study.The demographic information and medical history data of them were recorded and levels of serum proteins and enzymes were measured,and the metabolic syndrome (MS) was diagnosed according to IDF criteria.Results Serum protein contents of schizophrenic patients (total protein (71.14 ±6.13) g/L,albumin (44.56 ±4.24)g/L,globulin(26.35 ±5.04) g/L,apoprotein A(10.97 ± 0.27) g/L,and apoprotein B (0.69 ± 0.25) g/L) were significantly lower than control group (79.96 ± 6.10) g/L,(49.44 ±5.63) g/L,(30.52 ±4.00) g/L,(10.97 ±0.27) g/L,and(0.69 ±0.25)g/L (P<0.01).Urea nitrogen ((4.36± 1.36) mmol/L) was lower than control group ((5.22 ± 1.31) mmol/L) and C-reaction protein ((3.17 ± 6.58) mg/L) was higher than control group (1.35 ± 1.83) (P < 0.01).Alanine aminotransferase ((24.28 ± 32.76) IU/L),a-L Fucosidase((17.49 ± 4.83) U/L),adenosine dehydrogenase((17.81 ± 5.67) U/L),and creatine kinase isoenzyme((10.50 ±4.92)IU/L) were higher than control group (18.12 ±9.77)IU/L,(15.98 ± 3.58)U/L,(11.75 ±5.48) U/L,and (9.12 ±3.62)IU/L,P<0.01),but AST isoenzyme ((5.97 ±4.97) U/L)was lower than control group ((7.05 ± 6.72) U/L).Alanine Aminotransferase,alkaline phosphatase,γ-glutamyl transpeptidase,and a-L Fucosidase,AST isoenzyme and cystatin-c of schizophrenic patients with MS were significantly higher than non-MS patients(P < 0.05).Conclusion There are significant metabolic disorders of proteins and enzymes in patients with schizophrenia,and abnormal changes of many enzymes are significantly associated with metabolic syndrome.

Quality control of traditional Chinese medicine (TCM) has become bottlenecks of TCM industry devel-opment and TCM international recognition. To solve the retational problems, we explored the establishment of new quality control method based on efficacy and safety. Firstly, material basis of TCM efficacy was investigated deeply and systematically. Then, quality control method based on efficacy was established by using active ingre-dients as markers. We also establish detection methods based on safety, such as pesticide residues, heavy metals and harmful elements , mycotoxins .

AIM:To establish a specific method for the identification of 26 chemical drugs added illegally into analgesic-antipyretic traditional Chinese medicines and health food. METHODS: The liquid chromatography-ion trap mass spectrometry method was used.Comparing with retention time and spectrums of references in library set up by ourselves,the target compounds in sample were screened and identified. RESULTS: Sixty samples were tested and Naproxen,Ibuprofen and Aspirin were detected out. CONCLUSION: The method is accurate,sensitive and easy to operate, which is first reported in China and so many compounds could be detected at the same time.
