Chinese Journal of Clinical Pharmacology and Therapeutics 1999;0(04):-
AIM: To observe the effect of sibutramine in the treatment of obesity with different body weight. METHODS: Forty overweight subjects were divided into three groups according to their BMI: Group 1 (n=10), the early stage of obesity; Group 2 (n=11), obesity in degree Ⅰ; and Group 3 (n=19), obesity in degree Ⅱ. The patients conformed to the same standards of diet, sports and life style, and then took sibutramine 10 mg a day for 12 weeks. RESULTS: After taking the medicine for two weeks, the efficacy rate was 45.5 % (5) in Group 2 and 94.7 % (18) in Group 3 (P
2.11? Hydroxysterold dehydrogenases and type 2diabetes mellitus
Chinese Journal of Endocrinology and Metabolism 1986;0(03):-
11? Hydroxysterold dehydrogenases (11?-HSDs )catalyse the interconversion of active glucocorticoids(cortisol,corticosterone )and their inert 11?-keto derivatives(cortisone,11-dehydrocorticosterone)They play an important role in regulating the local glucocorticoids activities.Glucoeorticoids can induce insulin resistance.The alteration of 11?-HSD activities in tissues such as liver ,adipose tissue, is closely relevant to some common disorders,including obesity and type 2diabetes mellitus.
3.Relationship between gastric cancer and the expressions of IL-6,IL-6 receptor and proliferating cell nuclear antigen
Medical Journal of Chinese People's Liberation Army 2001;0(07):-
Objective To detect the expression of IL-6 in peripheral blood of patients with gastric cancer,as well as the expressions of IL-6,IL-6 receptor(IL-6R) and proliferating cell nuclear antigen(PCNA) in the neoplastic tissue in order to investigate the clinical significance of such expressions in looking for a convenient and effective way for the diagnosis and therapy of gastric cancer.Methods Enzyme-linked immunosorbent assay(ELISA) was employed for the parallel semi-determination of IL-6 levels in the peripheral blood of 30 patients with gastric cancer,as well as the levels of IL-6 and IL-6R in the neoplastic and adjacent tissues.The expression of PCNA in the neoplastic tissues was determined with immuno-histochemistry technique.Moreover,the correlation was comprehensively analyzed among IL-6,IL-6R,PCNA and the clinicopathologic findings of gastric cancers.Results The IL-6 levels in both peripheral blood and neoplastic tissues of 30 patients were significantly higher than those of the normal controls.The IL-6 levels in peripheral blood decreased significantly after operation;the IL-6 and IL-6R levels in cancer tissues were significantly higher than those in their adjacent tissues with a positive correlation between IL-6 and IL-6R levels.The expressions of IL-6,IL-6R and PCNA in both peripheral blood and neoplastic tissues of patients were positively related to the clinical manifestation of gastric cancer,including the differentiation degree of cancer cells,tumor size,infiltration extent and the metastasis of cancer cells.Conclusions IL-6,IL-6R and PCNA are the important factors which affect the degree of malignancy of the gastric cancer concerned,and they also,reflect the possibility of infiltration and metastasis of cancer cells.The IL-6 level in peripheral blood and the levels of IL-6,IL-6R and PCNA in tumor tissues of patients with gastric cancer are obviously high.The expression levels of all these factors are correlated with the clinicopathologic findings of gastric cancer.An adequate determination of IL-6 and PCNA is of benefit to the diagnosis and treatment of gastric cancer,and to the judgment of the course and prognosis of gastric cancer.
4.A reverse dot blot method for genotyping of NAT2 in Chinese subjects
Chinese Pharmacological Bulletin 2003;0(11):-
Aim To establish a simple reverse dot blot m ethod (RDB) for detecting the genotype of NAT2 in Chinese people. Methods PCR was performed to obtain a biotin labeled DNA fragment. Allele specific oligonucleotide probes were spotted onto a nylon membrane. The DNA fragment hybridized with the membrane under stringent conditions. Finally, a nonradioactive colorimetric reaction was used to detect five mutants of NAT2. NAT2 genotypes of 48 patients with pulmonary tuberculosis were detected with RDB.Results The results obtained from RDB were in consistent with those from allele specific amplification. The NAT2 allele frequencies of *5, *6, *7 were 1.04%, 22.9% and 15.6%, respectively.Homozygous wildtype,heterozygous mutant and homozygous mutant subjects were 33.3%, 54.2% and 12.5%, respectively.Conclusion RDB method was proved to be accurate and convenient, it can be u sed in rational drug therapy.

Journal of Practical Radiology 2016;32(10):1545-1548
Objective To evaluate the radiofrequency ablation in treatment of primary and recurrent liver cancer and to explore the risk factors affecting prognosis.Methods 1 64 patients with primary and recurrent liver cancer underwent radiofrequency ablation treatment.The clinical data including liver function before and after treatment,alpha-fetoprotein (AFP),the rate of relapse and survivalwere retrospectively analyzed.The univariate Logistic regression analysis was used to analyzed the risk factors associated with the prognosis.Then the risk prognostic factors were analyzed using COX risk model.Results After treatment,AFP and liver function were significantly improved in patients (P<0.05);Complete tumor ablation rate was 87.50%.After cancer treatment 1,2,3,4 years,the recurrence rate was 17.9%,29.9%, 45.9% and 55.0% respectively.Conclusion Radiofrequency ablation is an effective treatment for primary liver cancer treatment,the risk factors affecting prognosis include tumor differentiation,tumor recurrence,TNM stage,AFP,intraoperative blood transfusion, surgical,cancer and surgical site before surgery transaminase levels.

Journal of Xi'an Jiaotong University(Medical Sciences) 2017;38(1):108-112
ABSTRACT:Objective To investigate the clinical value and application indications of the second biopsy-cervical conization in the diagnosis and treatment of cervical lesions.Methods We selected 413 patients from Department of Gynecology and Obstetrics,General Hospital of Jinan Military Command,who received cervical multi-point biopsy pathology IA for cervical cancer and cervical conization (LEEP knife)of the second biopsy between January 2012 and October 2015.Their data were retrospectively analyzed.Results Compared with cervical multi-point biopsy, the second biopsy-cervical conization after operation had pathological upgrade in 10.65% (44/413),agreement in 73.37% (303/413),and reverse (pathological levels drop and overcast)in 15.98%(66/413).Cervical multi-point biopsy and the second biopsy-cervical conization significantly differed in the diagnosis of cervical low-level intraepithelial lesion,high-grade intraepithelial lesions,and early invasive cancer (IA)(T=21.740,v=3-1=2,P<0.05).Before conization high-risk type HPV infection positive rate was 71.91%(297/413);after operation it was 86.36% (38/44)in upgrade pathology and 70.20% (259/369)in non-upgrade one.And thin prep cytologic test (TCT)showed that the positive rate (ASC-US and above)was about 87.89% (363/413), of which about 11.85% (43/363)was pathological upgrade after conization.The positive rates of high-risk type HPV infection and TCT result (ASC-US and above)in cervical lesions differed significantly between pathological upgrade and non-upgrade after conization (χ2=5.092,P<0.05,χ2=4.476,P<0.05).Conclusion The second biopsy-cervical conization technique as a means of reevaluation of cervical pathological changes in diagnosis and treatment of cervical biopsy under colposcopy can significantly improve diagnosis rate,reduce misdiagnosis and occult cervical cancer,but its clinical application has some indications.

Journal of Clinical Neurology 1988;0(02):-
Objective To evaluate the relationship between concentrations of nitric oxide (NO) and antigen-specific immunoglobulin G (IgG) in CSF and intracranial hypertension and epilepsy in patients with neurocysticercosis.Methods The NO concentration and the IgG level were measured in 40 cases of neurocysticercosisk, and the results were compared according to the patients whether had intracranial pressure or epilepsy. 23 patients with varicosis of great saphenous vein required subarachnoid anesthesia were served as control group.Results Compared with control group, the NO concentration in CSF significantly increased in patient group (P0.05) in the patients with epilepsy as compared with the cases without epilepsy.Conclusions The CSF NO concentrations are higher in the patients with neurocysticercosis who had intracranial hypertension or epilepsy. The IgG levels are also increased in the patients who had intracranial hypertension.
