Objective To explore the association of Crohn's disease (CD) with T cell immunoglobulin and mucin domain 3 (Tim-3) gene polymorphisms in patients of Zhejiang Han population in China.Methods A total of 308 CD patients and 573 age-and sex-matched healthy controls were enrolled in our study.Two single nucleotide polymorphisms (SNPs) of Tim-3 (rs1036199 and rs10515746) were examined by the improved multiple ligase detection reaction technique (iMLDR).Analyses of linkage disequilibrium and haplotype were also performed by Haploview 4.2 software in all study subjects.Results In general,the allele and genotype frequencies of Tim-3 (rs1036199 and rs10515746) were not statistically different between CD patients and the controls (all P >0.05).According to the Montreal Classification,CD patients were divided into different subgroups.The variant allele (C) and genotype (AC + CC) of rs1036199 were more frequent in CD patients with penetrating diseases than in the controls (10.4% vs 1.7%,P =0.002;20.8% vs 3.5%,P =0.023).Similar conclusions were also drawn for the variant allele (A) and genotype (CA + AA) of rs10515746 in patients with penetrating diseases when compared with the controls (10.4% vs 2.2%,P =0.000;20.8% vs 4.2%,P =0.033,respectively).The two SNPs of Tim-3 were in strong linkage disequilibrium (D'=1.0,r2 =0.928).The haplotype (AC) formed by their wild-type alleles (A) and (C) was decreased in patients with penetrating CD compared with the controls (89.6% vs 98.3%,P =0.000).However,the haplotype (CA) formed by their variant alleles was more frequent in patients with penetrating CD than in the controls (10.4% vs 1.6%,P =0.000).Conclusions Tim-3 (rs1036199 and rs10515746) variations might be correlated with the enhanced risk of penetrating diseases in CD patients.Furthermore,the haplotype (AC) and (CA) formed by the two SNPs might be a protective and a risky factor for penetrating CD respectively.

Objective To evaluate the efficacy and safety of recombi-nant human granulocyte colony-stimulating factor ( rhG-CSF) used for chemotherapy-induced myelosuppression in small cell lung cancer (SCLC) patients. Methods Two hyndreds twenty-two cases suffering from small cell lung cancer of PLA General Hospital from 2002 to 2006 were chosen in our retrospective study, and 62 of these cases, used rhG-CSF after chemotherapy,were included in a statistics analysis. Results rhG-CSF was effective for chemotherapy-induced myelosuppression reactions and increasing significantly the number of neutropenia leukocyte and WBC (white blood cell). Average duration of recovery was 3 days and the effective rate was 95. 2%. Conclusion rhG-CSF showed high overall response rate of chemotherapy-induced myelosuppression reaction with only a few adverse reactions. But dosage and administration should be adjusted to different patients in different situations.
3. Introduction to the hotspots and forefront of 2018 Myasthenia Gravis Foundation of America′s Scientific Session
Chinese Journal of Neurology 2019;52(9):790-792
The authors introduced the hotspots and forefront of 2018 Myasthenia Gravis Foundation of America′s Scientific Session, including the research forefront and trend of the following: International research hotspots in the myasthenia gravis (MG) had been changed from the most common acetylcholine receptor antibody positive MG (AChR-MG) into other subtypes, particularly muscle specific tyrosine kinase receptor antibody positive MG; The efficacy of thymectomy was effective in the whole AChR-MG group, but not in other MG subgroups; Existing drugs in MG treatment can not achieve the expected effect, so endless new drug development had become a hot field of MG research; In terms of basic research, more attention had been paid to exploring the specific mechanisms involved in MG pathogenesis, including the study of antigen specific B cells and even antigen specific T cells.

OBJECTIVETo investigate the expression of enhancer of zeste homolog 2 (EZH2) in esophageal squamous cell carcinoma and its association with the prognosis of postoperative patients.
METHODSSurgical specimens were obtained from 102 patients with esophageal squamous cell carcinoma undergoing radical resection in our hospital from 1996 to 2006. Immunochemistry was employed to examine EZH2 protein expressions in the specimens, including 102 carcinoma tissue specimens, 30 adjacent tissue specimens and 30 normal esophageal tissue specimens. The expression levels of EZH2 were analyzed in relation to the clinicopathological parameters of the patients including gender, age, tumor differentiation, TNM, and lymph node metastasis. The postoperative patients were followed up to analyze the association of EZH2 expression with the clinical outcomes.
RESULTSThe esophageal squamous cell carcinoma tissue showed a higher EZH2 expression than the adjacent and normal esophageal tissues. EZH2 expression was higher in poorly differentiated carcinoma than in well differentiated tissue, and also higher in cases with lymph node metastasis than those without; the expression was higher in TNM stage II/III patients than in stage I patients but lower than in stage IV patients. The patients with low EZH2 expression was found to have a longer survival time than those with high EZH2 expression (P<0.05).
CONCLUSIONEZH2 plays an important role in the differentiation and metastasis of esophageal squamous cell carcinoma, and a high EZH2 expression is associated with a poor outcome in the the postoperative patients.

OBJECTIVETo explore the expression of uncoupling protein-2 mRNA in brown adipose tissue, white adipose tissue and skeletal muscle of diet-induced obesity-resistant (DIO-R) rats.
METHODSFifty male Sprague-Dawley (SD) rats were randomly divided into a control group and a high-fat group and fed with basic diet and high-fat diet respectively for 13 weeks. DIO-R and DIO rats were selected according to their body weight. The change of body weight and the intake of total calorie were observed. Reverse transcription-polymerase chain reaction (RT-PCR) was used to measure the expression of UCP2 mRNA in rat.
RESULTSBody weight and total calorie intake in DIO-R rats (425.1 +/- 27.1) g, (31,693 +/- 946) kJ were significantly lower than those in DIO rats (489.7 +/- 20.5) g, (34,363 +/- 1465) kJ. The peak area of UCP2 mRNA in white adipose tissue in DIO-R rats was 352 +/- 30 and in DIO rats was 101 +/- 12. The peak areas of UCP2 mRNA in skeletal muscle in DIO-R and DIO rats were 130 +/- 15 and 170 +/- 12, respectively. The peak areas of UCP2 mRNA in brown adipose tissue of DIO and DIO-R rats were 124 +/- 14 and 147 +/- 19, respectively.
CONCLUSIONThe expression of UCP2 mRNA in white adipose tissue of DIO-R rats increased significantly. These results suggest that obesity-resistance was associated with a tissue-specific increase in UCP2 expression.

OBJECTIVEIn order to explore the expression of hormone-sensitive lipase (HSL) mRNA in white adipose tissue of diet-induced obesity-resistant (DIO-R) rats.
METHODSFifty male Sprague-dawley (SD) rats were randomly divided into control group and high-fat group and they were fed with basic diet and high-fat diet respectively for 13 weeks. DIO-R and DIO rats were selected according to their body weight and the quantity of energy intake, then observing changing of the body fat content, the level of serum growth hormone was determined by radioimmunoassay and the level of the HSL mRNA in white adipose tissue was determined by RT-PCR.
RESULTSThe body fat content of DIO-R rats were lower than those of DIO rats (P < 0.05). The level of serum growth hormone of DIO-R rats were higher than those of DIO rats (P < 0.05). High fat diets increased the level of the HSL mRNA in DIO-R rats.
CONCLUSIONIncreasing expression of HSL in white adipose tissue may play a part of role in resisting diet-induced obesity of rats.
