Risk analysis of depression among adult patients with epilepsy of different sex: a retrospective single-center study from China.

Objective: To determine sex differences in the prevalence of depression and assess the risk factors for depression among adult patients with epilepsy from the Dali area of China. Methods: We retrospectively analyzed the clinical data of adult patients with epilepsy who visited the First Affiliated Hospital of Dali University from January 2017 to January 2022. Patient Health Questionnaire-9 was used to assess depressive symptoms in patients with epilepsy. The risk factors of depression were analyzed by binary logistic regression among different sex in patients with epilepsy. Results: There were significant sex differences in depression in patients with epilepsy (p < 0.001), and females were 4.27 times more likely to suffer from depression than males (95% confidence interval: 3.70-4.92). The risk factors for depression among female patients with epilepsy included occupation (p < 0.001), years with epilepsy (p < 0.001), seizure frequency (p < 0.001), seizure type (p < 0.001), etiology (p < 0.001), number of antiseizure medications used (p < 0.001), antiseizure medications (p < 0.001), and electroencephalogram findings (p < 0.001). The risk factors for depression among male patients with epilepsy included age (p < 0.001), ethnicity (p < 0.001), occupation (p < 0.001), years with epilepsy (p < 0.001), seizure frequency (p < 0.001), seizure type (p < 0.001), etiology (p < 0.001), number of antiseizure medications used (p < 0.001), antiseizure medications (p < 0.001), and electroencephalogram findings (p < 0.001). Conclusion: Adult female patients with epilepsy had a higher risk of depression than adult male patients with epilepsy. There were sex differences in the risk factors associated with depression among patients with epilepsy.

[Recombinant Aspergillus niger glucose oxidase expressed in Trichoderma reesei].

It was expected that recombinant Aspergillus niger glucose oxidase could be expressed in Trichoderma reesei with stable activity. T. reesei CBHI promoter--CBHI ss. gene--A. niger glucose oxidase gene--T. reesei CBHI terminator--A. nidulans gpd promoter--E. coli Hygromycin B phosphotransferase gene--A. nidulans trpC terminator--pUC19 (pCBHGOD) vector was constructed in E. coli DH5alpha by PCR application and gene cloning methods. T. reesei QM9414 protoplast was transformed by T. reesei CBHI promoter-CBHI ss. Gene--A. niger glucose oxidase gene--T. reesei CBHI terminator-A. nidulans gpd promoter--E. coli Hygromycin B phosphotransferase gene--A. nidulans trpC terminator linear DNA fragment (CBHGOD fragment) that was made by digestion of pCBHGOD with Kpn I. T. reesei mutant clone with homologous recombinant A. niger glucose oxidase gene was selected by PCR method. Recombinant glucose oxidase was produced by mutant T. reesei strain under induction of wheat straw for 5 days. Recombinant glucose oxidase molecular mass was showed the same as native A. niger glucose oxidase standard from Sigma company by Western blot analysis. Recombinant glucose oxidase activity was 25u/mL in medium. The yield was 0.5 g/L in comparison with Sigma company glucose oxidase standard. There was no recombinant GOD degradation during Trichoderma reesei cultivation that was showed in Western blot analysis. Trichoderma reesei has capability to be a new recombinant host for Aspergillus niger GOD production.

[Determination of cholesteryl palmitate in Oviductus Ranae by HPLC].

OBJECTIVE: To develop a new method for the determination of cholesteryl palmitate in Oviductus Ranae. METHOD: A HPLC method was set up, using Zorbax Silica column and cyclohexane-diethyl ether (40:1) as mobile phase with a flow rate of 1.0 mL x min(-1), and the UV detection wavelength was 203 nm. RESULT: The calibration curve was linear over the range of 0.60-8.92 microg (r = 0.9997), the average recovery of the method was 98.4%. RSD 1.8% (n = 6). CONCLUSION: The results showed that method was reliable and accurate.
