Expression conditions of induction strategies for the cytoplasmic inclusion bodies (IBs) production of liver targeted interferon IFN-CSP by recombinant Escherichia coli (E. coli) BL21 (DE3) were optimized in shake-flask cultures in this study. The factors of the optimized protocol included in the present study were pH, inducer IPTG (isopropyl beta-D-thiogalactoside) concentration, culture growth temperature, incubation time and induction point. The effects of those factors were investigated by 'single variable at a time' method, aimed to analyze characterization of the recombinant strain. Orthogonal experimental design was further used to optimize the above critical factors for IFN-CSP production. According to the expression optimization result, it was confirmed that the main influence factors were cell density and induction temperature. The IFN-CSP gene expression optimized conditions were: pH value of the culture medium was 6.0, culture temperature 37 degrees C, adding IPTG to final concentration 0.4 mmol/L when the recombinant strain growth density OD600 achieved 0.8 and induction time 4 h. At this point, the IBs represented 74.3% of the total cellular protein. Compared with the non-optimized condition, IFN-CSP production obtained in optimized induction strategies were increased by approx. 1.2-fold. The optimized induction strategy yielded 688.8 mg/L of IFN-CSP, providing experimental data to study the biology activity and productive technology of IFN-CSP.

ObjectiveTo investigate the immunity and seroprevalence of hepatitis A and to identify the risk factors of hepatitis A infection in 0-18 year-old children and adolescents in Shanghai.MethodsSubjects were enrolled by stratifying and clustering random sampling method.Questionnaire interview was applied to investigate the socio-demographic and behavioral factors related to hepatitis A virus (HAV),and information on HAV immunization was abstracted from the immunization registration book of each subject.The enzyme-linked immunosorbent assay (ELISA) was used to qualitatively detect HAV IgM and quantitatively measure total HAV antibody in all subjects.Risk factors associated with HAV among the subjects without HAV vaccination were analyzed.ResultsA total of 2431 subjects were enrolled in the present study with negative HAV IgM antibody and total HAV antibody in 1483 subjects were sero-positive with positivity rate of 61％.Total HAV antibody positivity rates were declined with age increasing and were significantly higher in subjects with HAV vaccination than those without HAV vaccination records.Salad food,eating together without food separation in school and endoscopy inspection were risk factors for HAV infection.ConclusionsHAV vaccination strategies remarkably improve the total HAV antibody seropositive rate in children and adolescents in Shanghai.The risk of HAV infection exists if HAV vaccination is not administrated comprehensively.Therefore,strengthening HAV vaccination and health education are important for children and adolescents to prevent and control of hepatitis A in Shanghai.

Objective: To explore the effect of group cognitive behavioral therapy (GCBT) on cognitive control among college students with high obsessive compulsive traits, to provide basic information for the psychological counseling intervention for college students. Methods: From March to April 2019, 687 students were conveniently selected from 2 universities in Hefei. According to the inclusion and exclusion criteria, 58 students with high obsessive traits were selected and divided into experimental group ( n =29) and control group ( n =29) by random number table method. The experimental group received cognitive behavioral group counseling for 4 weeks (1.5 h each time, twice a week), while the control group receive no intervention. The Obsessive Compulsive Inventory Revised (OCI-R), Stroop Color Word Test (SCWT), Digital Span Test (DST), and Wisconsin Card Sorting Test (WSCT) were used to assess in two groups at baseline and 4 weeks later. Results: After 4 weeks, the scores of OCI-R in the GCBT group (10.28±7.22) was lower than that of in the control group (15.90±10.20) ( t=2.42, P<0.05). Before and after intervention, compared with the control group [(21.89±6.63, 20.52±7.37)s, (8.62±4.43, 8.04±4.84)s] in Stroop C and Stroop interfere effects (SIE), the GCBT group [(22.14±4.92, 16.81±3.43)s, (8.36±3.87, 4.82±1.86)s], the interaction of time group was statistically significant ( F =14.60, 10.54, P <0.05). Compared with the control group (6.21±1.35, 6.55±1.45)times, the scores of DST reverse in the GCBT group (6.31±1.44, 7.24±1.38) times were statistically significant ( F=3.96, P <0.05). Conclusion It suggests that cognitive behavioral group counseling can improve the inhibitory control and working memory of college students with high obsessive compulsive traits, but does not change the cognitive flexibility.

We present a case of a postmenopausal women with hyperandrogenic symptoms and virilization signs , such as hirsutism, alopecia, acne and clitoromegaly, which was pathologically confirmed to be an ovarian steroid cell tumor, not otherwise specified(NOS). The levels of testosterone, dehydroepiandrosterone sulfate and estradiol in serum were increased, while the levels of luteinizing hormone and follicle stimulating hormone were decreased. Computed tomography(CT) scan and magnetic resonance imaging(MRI) identified a solid, left ovarian tumor and detected an additional tumor of hypodensity in the left adrenal gland. ACTH stimulation test, hCG stimulation test, adrenal and ovarian vein sampling indicated that excessive androgens were derived from the ovary. After the injection of gonadotropin hormone analogues(GnRHa), testosterone levels dropped to the normal range. Laparoscopic bilateral adnexectomy was performed, and pathology indicated NOS. The purpose of this report is to improve the understanding of NOS with hyperandrogenic presentation.

Objective:To evaluate the clinical efficacy, tolerability and safety of adjunctive perampanel in focal epilepsy patients≥12 years old.Methods:One hundred and nineteen focal epilepsy patients≥12 years old accepted adjunctive perampanel in Department of Neurology, First Affiliated Hospital of Guangxi Medical University from July 2020 to December 2022 were chosen. At 1-3 months, 4-6 months, 7-9 months and 10-12 months after adjunctive perampanel, seizure frequency changes every 28 d, medication retention rate and adverse reactions were recorded to evaluate the clinical efficacy (a reduction in seizure frequency≥50% from baseline was defined as overall valid treatment), tolerability and safety of adjunctive perampanel. According to efficacy results after adjunctive perampanel of 4-6 months (short-term) and 10-12 months (long-term), these patients were divided into valid group and invalid group; and the influencing factors for short-term and long-term efficacy were analyzed.Results:At 1-3, 4-6, 7-9, 10-12 months after adjunctive perampanel, reduction in seizure frequency every 28 d was 66.7% (24.3%, 97.2%), 77.5% (48.6%, 100%), 94.6% (50%, 100%), 100% (70.9%, 100%), enjoying overall valid rate of 60.2% (59/98), 75.0% (7/76), 78.9% (45/57), 86.5% (32/37). The retention rate at 3, 6, 9 and 12 months after adjunctive perampanel was 85.2% (98/115), 67.9% (76/112), 54.3% (57/105), 41.1% (37/90). Adverse reactions were reported in 33 patents (27.7%), mainly with dizziness and secondly with mental symptoms. After short-term and long-term adjunctive perampanel, no significant difference was noted in gender, initial age of adjunctive perampanel, course of disease, etiology, EEG results, imaging results, number and type of combined anti-seizure drugs, or maximum dose of pirampanel between the valid group and invalid group ( P>0.05). Conclusion:Perampanel has good efficacy, tolerability and safety in adolescents and adults≥12 years old with focal epilepsy; no clear influencing factors for pirampanel valid treatment is found so far.

Objective: To investigate periodontal status of patients with pre-diabetes and evaluate the prevalence of periodontal pathogens in oral cavity. Methods: All the subjects were under regular care in urban area of Beijing, including 88 subjects with normal blood glucose (normal blood glucose group), 27 pre-diabetic patients (pre-diabetic group), 58 well-controlled diabetic patients (glucose well controlled group) and 72 poor-controlled diabetic patients (glucose poor controlled group). Whole unstimulated saliva samples were collected before periodontal examination. Periodontal parameters, including plaque index (PLI), probing depth (PD), bleeding index (BI), bleeding on probing (BOP) and clinical attachment loss (CAL), were examined at mesial-buccal and distal-lingual sites of each tooth. Number of missing teeth was recorded. DNA was extracted from the salivary deposition, Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), Treponema denticola (Td), Campylobacter rectus (Cr), and Prevotella nigrescens (Pn) were detected by using PCR method based on 16SrRNA. Periodontal status and prevalence and quantity of the pathogens under various blood glucose states were compared. Results: The PD scores of four groups had no statistical differences. The CAL [(2.29±1.35) mm] and the number of missing teeth[2.0 (7.0)] in pre-diabetic group were significantly lower than that in glucose poor controlled group [(3.07±1.45) mm, P=0.04 and 5.0 (10.0), P=0.04, respectively]. The number of missing teeth in pre-diabetic group [2.0 (7.0)] was significantly lower than that in glucose well controlled group [5.0 (9.0), P=0.02]. The percent of bleeding on probing [BOP(+)%] in pre-diabetic group [(63.89±20.03)%] was significantly higher than that in normal blood glucose group [(54.51±22.29)%, P=0.04] and glucose well controlled group [(53.12±21.77)%, P=0.03]. The prevalence of Pg in pre-diabetic group (81.5%) was significantly higher than that in glucose poor controlled group (54.2%, P=0.02). The prevalence of Tf in pre-diabetic group (96.3%) was significantly higher than that in glucose poor controlled group (76.4%, P=0.01). Meanwhile the quantity of Pg [1.58 (4.75)] and Tf [5.46 (7.77)] in pre-diabetic group were significantly higher than that in glucose poor controlled group [0.60 (1.87), P=0.01 and 1.63 (3.06), P<0.01, respectively]. The quantity of Pn [0.85 (1.68)] in pre-diabetic group was significantly higher than that in normal blood glucose group [0 (1.02), P=0.04]. Conclusions Pre-diabetic patients showed severe periodontal infection and BOP(+)% than other three groups and had high risk-level of periodontitis.

Objective This study aims to examine the association between leptin and postpartum depression symptoms. Methods Two hundred pregnant women were enrolled and their prenatal serum leptin levels were measured by using enzyme-linked immunosorbent assay (ELISA). The state of depression was first assessed on the third day after delivery and reassessed by a telephone follow up on the 42nd day using the Edinburg postnatal depression scale (EPDS) after delivery. Patients with postpartum depression symptoms with EPDS score ≥13 points after 3 days postpartum or 42 days postpartum were recruited as the depressive symptom group. Results The medians and lower and upper quartiles of the prenatal serum leptin levels in the depressive symptom group (the 3rd day) and the control group were 1.36 (1.15, 1.68) μg/L and 1.49 (1.28, 1.91) μg/L, respectively. After normal conversion, the serum leptin level was significantly lower in the depressive symptom group than in the control group (P=0.021). The medians and lower and upper quartiles of the prenatal serum leptin levels in the depressive symptom group (the 42nd day) and the control group were 1.17 (1.01, 1.36) μg/L and 1.50 (1.29, 1.90) μg/L, respectively. After normal conversion, the serum leptin level was significantly lower in the depressive symptom group than in the control group (P＜0.001). EPDS scores 3 days postpartum (r=-0.199, P=0.014) and 42 days postpartum (r=-0.254, P=0.002) were negatively correlated with prenatal serum leptin levels. Multiple logistic regression analysis showed that the prenatal leptin levels were associated with depressive symptoms at 42 days postpartum (OR=0.026, P=0.001). Conclusion Prenatal serum leptin levels may be associated with postpartum depressive symptoms, and high levels of leptin are protective factors for postpartum depression.
