Rapeseed oil is one of the major raw materials for biodiesel production. The bottleneck of rapeseed oil-based biodiesel production at present is high cost of raw materials, which generally accounts for about 75% of total production cost. Current status and principal problems concerned in the production of biodiesel from rapeseed oil in China and other countries were introduced, based on which it was proposed to grow high-erucic acid rape in existing winter fallow fields and jointly produce biodiesel, erucic acid and its derivative products, and other highly valuable by-products such as glycerin and sterols from high-erucic acid rapeseed oil. The feasibility of this development strategy was analyzed in terms of product and market demand potential, economic benefits of enterprises, techniques and conditions of production, and source of raw materials. It was believed that the implementation of the strategy in China was of great significance in realizing rise and sustainable development of rapeseed oil-based biodiesel production, improving quality of biodiesel, promoting the development of biochemical engineering and many other industries, as well as in building a socialist new countryside.

Objective:To investigate the role of TCF7L2 gene polymorphism and related mechanisms in postmenopausal women with type 2 diabetes mellitus (T2DM) who are at high risk for osteoporosis (OP) .Methods:148 postmenopausal women with T2DM from Jan. 2019 to Jun. 2020 were selected as study subjects. Among them, 86 patients combined with OP (T2DM+OP group) and 62 patients without OP (T2DM group) were included, and 100 healthy postmenopausal women who underwent physical examination in our hospital during the same period were included as the control group. Fasting venous blood was extracted to detect clinical and bone metabolism indicators. Two SNP sites of TCF7L2, rs7901695 (T>C) and rs290487 (C>T) , were genotyped by capillary electrophoresis and section analysis (SNaPshot) . The relative mRNA expression of TCF7L2 gene was determined by quantitative real-time fluorescence quantitative PCR assay. To investigate the effects of overexpression and silencing of TCF7L2 on proliferation of rat osteoblasts, lentiviral vectors were constructed.Results:For rs7901695, TT, TC and CC genotypes in T2DM+OP group, T2DM group and control group were significantly different ( χ2=12.545, P=0.014) , and the frequency distribution of T and C alleles was significantly different among the three groups ( χ2=17.089, P<0.001) . For RS290487, CC, CT and TT genotypes of T2DM+OP group, T2DM group and control group were significantly different ( χ2=10.500, P=0.033) , and the frequency distribution of C and T alleles was significantly different among the three groups ( χ2=14.665, P=0.001) . For rs7901695, FPG and TG levels in T2DM+OP patients with CC+TC genotype were significantly higher than those with wild-type TT genotype (FPG: t=2.559, P=0.014; TG: t=2.034, P=0.036) , while serum calcium and 25OHD3 levels were significantly lower than those with Wild-type TT genotype (calcium: t=3.889, P<0.001; 25OHD: t=4.112, P<0.001) . For rs290487 site, serum calcium, BGP and 25OHD3 levels in T2DM+OP patients with TT+CT genotype were significantly lower than those with wild-type CC genotype, and the difference was statistically significant (calcium: t=3.751, P<0.001; BGP: 2.731, P=0.007; 25OHD3: t=3.225, P=0.002) . The relative mRNA expression level of TCF7L2 gene in T2DM+OP patients was significantly lower than that in T2DM group and the control group ( F=5.735, P<0.05) . With the increase of Allele C at rs7901695, the relative mRNA expression level of TCF7L2 gene decreased gradually ( F=5.723, P<0.05) . In addition, the proliferation rate of rat osteoblasts overexpressed by TCF7L2 was significantly increased, while the proliferation level of TCF7L2 silenced osteoblasts was significantly decreased ( F=7.846, P<0.05) . Conclusion:In postmenopausal WOMEN with T2DM, the variation of TCF7L2 gene will lead to the decrease of gene expression level, and the suppression of osteoblasts proliferation, thus participate in the pathogenesis of OP.

Objective To assess the associations of anti-Smith antibodies with clinical manifestations and disease activity in children with systemic lupus erythematosus (SLE).Methods According to SLE disease activity index (SLEDAI) score,72 children with SLE were divided into the active group and inactive group.An immunoblotting method was used to detect serum anti-Smith antibodies in these subjects.Chi-square test was conducted to assess the associations of anti-Smith antibodies with clinical manifestations and disease activity in these patients.Results Of these patients,28 (38.9％) were assigned into the inactive group,and 44 (61.1％) to the active group.Anti-Smith antibodies were detected in 17 (23.6％) patients,but not in the other 55 (76.4％) patients.Elevated incidence rate of kidney injury was observed in anti-Smith antibody-positive patients compared with anti-Smith antibody-negative patients (70.6％ (12/17) vs.41.8％ (23/55),P ＜ 0.05).Meanwhile,the positivity rate of anti-Smith antibodies was 31.8％ (14/44) in the active group,significantly higher than that in the inactive group (10.7％,3/28,P ＜ 0.05).Conclusions Anti-Smith antibodies are not only an important indicator for the diagnosis of SLE,but also a risk factor for disease exacerbation and kidney injury in children with SLE.

One case with fulminant type 1 diabetes during the third trimester of pregnancy was reported.If a patient manifests abrupt onset of hyperglycemia,nausea,vomiting,and bellyache during pregnancy or immediately after delivery,fulminant type 1 diabetes should be considered.

In this paper, metabolic networks of the Corynebacterium glutamicum GWY020 and the two de-rivatives carrying additional mutations HUI821and GUI089 were established and modified. The concentra-tions of extra-cellular metabolites were determined under sub-steady-state (50 h~52 h) of the batch culture. The metabolic flux distribution maps of the three strains were obtained, compared and analyzed. These re-sults indicate that the introduction of analog supersensitive marker or analog resistant marker skew the metabolic flux towards the formation of L-Arginine. This study revealed the usefulness of the metabolic flux analysis as a tool for verification of existing production strains. The analysis may play an important role in helping us to rationally re-design metabolism for further improvement of fermentation process.

OBJECTIVE:To provide reference for the development of pharmaceutical care for periconceptional women. METH-ODS:Probability proportionate to size sampling(PPS)method was adopted to select participants from periconceptional women in Yongchuan District. The participants were investigated by questionnaires about drug use safety knowledge,attitude and behavior. Ep-idata 3.0 software was used to establish database. The data were analyzed with SPSS 15.0 software. RESULTS:Totally 800 ques-tionnaires were distributed and then 779 valid questionnaires were collected with effective rate of 97.38%. The total awareness rate of knowledge about drug use safety was 57.69%. The awareness rate rise with the increase of educational level (P<0.01). The awareness rate was higher in pregnant women than in prepregnant ones,with statistical significance in most of the questions(P<0.05 or P<0.01). For questions about attitude for drug use safety,the positive answer rate was higher in pregnant women than in prepregnant ones,with statistical significance in most of the questions (P<0.01). Among 385 pregnant women,only 56.88% re-ceived folic acid following the WHO recommendation. Of 181 pregnant women who had taken medicine,8.29% indicated that the physicians or pharmacists did not inform that whether the medicine affected pregnancy. CONCLUSIONS:Among periconceptional women,awareness rate of drug use safety is in low level and varied by their educational levels. There are difference in awareness rate of drug use safety and attitude between prepregnant women and pregnant woman. Drug use behavior of pregnant woman is to be modified.

Objective To explore the clinical value of gastric bare area (GBA) for the prognosis of gastric fundus and cardia carcinoma.Methods The data of 82 patients with gastric fundus and cardia carcinoma from January 2010 to December 2011 were retrospectively analyzed.The patients were divided into group A (49 cases) with cancer cell invasion in GBA and group B (33 cases) without invasion in GBA.All the patients underwent D2 gastrectomy plus surgical resection of GBA and were treated by 6 cycles of postoperative FOLFOX-4 chemotherapy scheme.Postoperative follow-up and survival analysis were carried out for patients in both groups.Results According to survival analysis (Kaplan-Meier method),the postoperative 1-,2-and 3-year cumulative survival rates of the patients in group A were 91.8 ％,57.3 ％ and 29.0 ％,respectively,while those of the patients in group B were 93.9 ％,75.0 ％ and 48.2 ％,respectively.The median survival times of the patients in group A and group B were 27.0 months and 36.0 months,respectively,which was demonstrated existing statistical significance(X2 =4.972,P =0.026).Conclusions The prognosis of gastric fundus and cardia carcinoma patients with invasion in GBA by cancer cells is poor.Surgical resection of GBA may help to improve the prognosis of the patients with gastric fundus and cardia carcinoma.

Objective: To analyze the aberrant methylation of death-asscciated protein kinase (DAPK) gene in blood from non-small cell lung cancer (NSCLC) patients and to evaluate its clinical significance. Methods: A methylation-specific PCR was performed for the detection of promoter hypermethylation of DAPK gene in blood DNA from 65 cases of NSCLC patients,and the relation of the aberrant methylation of DAPK gene and the clinical pathological data was analyzed. Results: 30.8% (20/65) of the blood from 65 cases of NSCLC patients showed hypermethylation in DAPK promoter, whereas no methylated DAPK gene promoter was found in blood from normal control or patients with benign lung diseases. DAPK gene promoter methylation in blood did not strongly correlate with the pathological class, stage, metastasis and differentiation of NSCLC. Conclusion: Detection of the aberrant methylation of DAPK gene in blood DNA from NSCLC patients might offer an effective means for the earlier auxiliary diagnosis of the malignancy.
