Molecular Biology is a key basic professional course for all the students specializing in Biolo-gy,Biotechnology,and Bioengineering.With the promotion of double world-class project and first-class undergraduate construction,the development of English-taught course faces challenges.We started to teach the Molecular Biology course in English at the East China University of Science and Technology since 2019,the construction of Molecular Biology course has been reformed and practiced,including the combination of imagery,vividness and classroom teaching,the combination of advanced,cutting-edge and classical theories,and the comprehensive coverage of the teaching process,which has effectively pro-moted the construction and practice of Molecular Biology course.The Molecular Biology course taught in English greatly increased the students'professional and scientific research ability,international vision and English academic communication ability,comprehensive ability and satisfaction,and teachers'teaching and research ability.This course provides an effective reference for fostering innovative profes-sional first-class undergraduates and the construction of Molecular Biology course.

Objective To investigate the influence of modified Shashen Maidong Decoction combined with Camrelizumab immunotherapy plus chemotherapy on the efficacy,survival status and serum cytokeratin 19 fragment(CYFRA21-1)and neuron-specific enolase(NSE)levels in patients with advanced non-small cell lung cancer(NSCLC).Methods Forty patients with advanced NSCLC of lung-stomach yin deficiency with intense heat-toxin type were randomly divided into a control group and a study group,with 20 patients in each group.The patients in the control group were given Camrelizumab immunotherapy plus chemotherapy,and the patients in the study group were given modified Shashen Maidong Decoction combined with Camrelizumab immunotherapy plus chemotherapy,with 21 days as a course of treatment and for a total of 4 courses of treatment.The changes of serum NSE and CYFRA21-1 levels in the two groups before and after treatment were observed,and the clinical efficacy,survival status and the incidence of toxic and side effects were compared between the two groups.Results(1)After 4 courses of treatment,the total effective rate of the study group was 70.00%(14/20),which was significantly higher than that of the control group(9/20,45.00%),but the intergroup comparison(tested by chi-square test)showed that the difference was not statistically significant(P＞0.05).(2)After 2 years of follow-up,the overall survival(OS),time to progression(TTP),and progression-free survival(PFS)of the patients in the study group were significantly prolonged compared with those in the control group(P＜0.01).(3)After treatment,the serum NSE and CYFRA21-1 levels of the patients in the two groups were decreased compared with those before treatment(P＜0.05),and the decrease of serum NSE and CYFRA21-1 levels in the study group was significantly superior to that in the control group(P＜0.01).(4)The incidence of toxic and side effects in the study group was 25.00%(5/20),which was significantly lower than that of 65.00%(13/20)in the control group,and the intergroup comparison showed that the difference was statistically significant(P＜0.05).Conclusion Modified Shashen Maidong Decoction combined with Camrelizumab immunotherapy plus chemotherapy has satisfactory therapeutic effect on patients with advanced NSCLC,which can reduce the toxic and side effects of chemotherapy,lower the level of serum tumor markers,and prolong the survival period and time to progression(TTP)of the patients.

Objective To explore the effects of different fractionation doses,fractionation methods,and other related parameters on the peripheral blood lymphocyte count of patients with liver cancer receiving CyberKnife radiotherapy.Methods The clinical data of 90 patients with liver cancer receiving CyberKnife radiotherapy in our hospital were retrospectively analyzed.The peripheral blood lymphocyte counts of patients 1 week before CyberKnife radiotherapy and 1 week,1 month and 3 months after treatment were determined.The effects of different prescribed doses,fractionation doses and numbers of fractionations on the peripheral blood lymphocyte count were analyzed.Results The peripheral blood lymphocyte counts of patients with different prescribed doses,fractionation doses and fractionation methods after CyberKnife treatment decreased to varying degrees compared with those 1 week before treatment(P<0.05).The peripheral blood lymphocyte counts of patients in the groups with≤5 fractionations and fractionation dose>7 Gy were significantly higher than those of patients in the groups with>5 fractionations and the fractionation dose≤7 Gy,respectively(P<0.05).There was no significant difference in peripheral blood lymphocyte counts between patients with different prescribed doses before and after CyberKnife treatment(P>0.05).Conclusion CyberKnife in the treatment of liver cancer with≤5 ractionations and a fractionation dose of>7 Gy is more beneficial to alleviate the decrease of lymphocyte count caused by Cyberknife treatment.

Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

Objective: To investigate the clinical features and long-term prognostic factors of diabetic patients with low or intermediate complexity coronary artery disease (CAD) post percutaneous coronary intervention (PCI). Methods: This was a prospective, single-centre observational study. Consecutive diabetic patients with SYNTAX score (SS)≤32 undergoing PCI between January and December 2013 in Fuwai hospital were included in this analysis. The patients were divided into two groups based on SS, namely SS≤22 group and SS 23-32 group. Multivariate Cox regression analysis was performed to identify independent factors related to poor 5-year prognosis. The primary outcomes were cardiac death and recurrent myocardial infarction, the secondary outcomes were all cause death and revascularization. Results: Of the 3 899 patients included in the study, 2 888 were men (74.1%); mean age was 59.4±9.8 years. There were 3 450 patients in the SS≤22 group and 449 patients in the SS 23-32 group. Compared with SS≤22 group, the incidence of revascularization was higher in SS 23-32 group (18.9% (85/449) vs. 15.2% (524/3450), log-rank P=0.019). There was no significant difference in all-cause death, cardiac death and recurrent myocardial infarction between the two groups (log-rank P>0.05). Multivariate Cox regression analysis showed that age (HR=1.05, 95%CI 1.02-1.08, P<0.001), chronic obstructive pulmonary disease (HR=3.12, 95%CI 1.37-7.07, P=0.007) and creatinine clearance rate (CCr)<60 ml/min (HR=3.67, 95%CI 2.05-6.58, P<0.001) were independent risk factors for 5-year cardiac death, while left ventricular ejection fraction (HR=0.94, 95%CI 0.91-0.96, P<0.001) was a protective factor. Previous PCI (HR=2.04, 95%CI 1.38-3.00, P<0.001), blood glucose level≥11.1 mmol/L on admission (HR=2.49, 95%CI 1.32-4.70, P=0.005) and CCr<60 ml/min (HR=1.85, 95%CI 1.14-2.99, P=0.012) were independent risk factors for 5-year recurrent myocardial infarction. The SS of 23-32 was independently associated with risk of revascularization (HR=1.54, 95%CI 1.09-2.16, P=0.014), after adjusting for residual SS. Residual SS was not a risk factor for 5-year prognosis. Conclusions: In diabetic patients with low-or intermediate complexity CAD, SS 23-32 is associated with increased risk of 5-year revascularization; the clinical characteristics of the patients are associated with the long-term mortality and recurrent myocardial infarction, but not related to revascularization.

The paper introduces professor ZHUANG Li-xing's clinical experience in treatment of dyskinesia of Parkinson's disease with acupuncture at triple-acupoint prescription. In pathogenesis, dyskinesia of Parkinson's disease refers to yang deficiency and disturbing wind. In treatment, acupuncture focuses on warming yang, promoting the circulation of the governor vessel, regulating the spirit and stopping trembling; and Baihui (GV 20), Suliao (GV 25) and Dingchanxue (Extra) are selected to be "trembling relief needling". In combination with Jin's three needling, named "three-trembling needling" "three-governor-vessel needling" and "three-spasm needling", the triple-acupoint prescription is composed. To ensure the favorable therapeutic effect, this prescription is modified according to the symptoms and the specific techniques of acupuncture are combined such as conducting qi, harmonizing yin and yang, and manipulating gently for reinforcing and reducing.

Objective:To investigate clinical efficacy and safety of dupilumab in the treatment of atopic dermatitis (AD) .Methods:An ambispective study was conducted on 123 AD patients treated with dupilumab in Department of Dermatology, the Second Xiangya Hospital of Central South University from July 2020 to March 2022, clinical data were collected, and efficacy and safety of dupilumab were evaluated. Primary outcomes included scores of eczema area and severity index (EASI) , patient-oriented eczema measure (POEM) , peak pruritus numerical rating scale (NRS) and dermatology life quality index (DLQI) before and after 4-, 8-, 12- and 16-week treatment, and adverse reactions and events were recorded. Comparison of scores before and after treatment was performed using paired t test or repeated measures analysis of variance, Mann-Whitney U test was used for the comparison of efficacy among patients with different types of skin lesions or different IgE levels, and multiple regression model based on robust standard errors was used to analyze factors influencing the efficacy. Results:Among the 123 AD patients, 107 were enolled into the efficacy analysis, and 85 (79.44%) completed at least 4 weeks of treatment, including 6 (7.06%) achieving EASI75 and 23 (27.06%) achieving EASI50, and the EASI, NRS, POEM, DLQI scores (10.41 ± 6.72, 4.12 ± 1.74, 8.60 ± 4.29, 7.81 ± 4.38, respectively) significantly decreased compared with those before treatment (18.08 ± 10.69, 7.21 ± 2.01, 16.88 ± 5.74, 12.95 ± 5.95, respectively; all P < 0.001) in the 85 patients. Among the 107 patients, 47 (43.93%) completed at least 16 weeks of treatment. Among the 47 patients, 23 (82.14%) of 28 adults and 17 (89.47%) of 19 adolescents and children achieved 75% or greater improvement in EASI score; the EASI, NRS, POEM and DLQI scores before the treatment all significantly differred from those 4, 8, 12, 16 weeks after the treatment (all P < 0.001) , and all the scores were significantly lower at weeks 4, 8, 12 and 16 than at the previous adjacent time points (all P < 0.05) . At week 4 during the treatment, the EASI improvement rate was significantly lower in the AD patients with prurigo nodularis than in those without ( U = 151.00, P = 0.006) , while there was no significant difference in the EASI improvement rate between the AD patients with xeroderma and those without ( P > 0.05) ; at week 16 during the treatment, there was no significant difference in the EASI improvement rate between patients with prurigo nodularis or xeroderma and those without (both P > 0.05) . Multiple regression analysis based on robust standard errors at week 16 showed that the improvement degree in the EASI score was not correlated with the type of skin lesions ( β = 3.20, P = 0.075) , but correlated with age ( β = -0.22, P = 0.030) , whether patients were in adulthood ( β = 9.54, P = 0.049) , immediate family history ( β = 7.46, P = 0.017) ; the improvement degree in the NRS score was correlated with the type of skin lesions ( β = 0.55, P = 0.032) , age ( β = -0.04, P = 0.033) , weight ( β = -0.05, P = 0.020) , whether patients were in adulthood ( β = 2.06, P = 0.003) and whether patients received combined treatment with antihistamines ( β = -1.91, P = 0.001) . Adverse reactions: among the 123 patients, 6 (4.88%) developed conjunctivitis, and 2 (1.63%) developed facial erythema. Adverse events: vitiligo-like changes occurred on the right forehead of 1 patient, and 3 patients discontinued the treatment with dupilumab due to Henoch-Sch?nlein purpura, distal axonal damage in peripheral nerves in both upper limbs, and epilepsy, respectively. The causal relationship between these adverse events and dupilumab was unclear. Conclusion:Dupilumab is effective in the treatment of AD with high overall safety, and can serve as a new treatment option for AD patients with an unsatisfactory response to traditional treatment.

Objective: This study aimed to investigate whether cytokine profiles and virological markers might add value in monitoring the effects of peginterferon (PEG-IFN) therapy for hepatitis B e-antigen (HBeAg) positive chronic hepatitis B (CHB). Methods: HBeAg positive patients with CHB were treated with PEG-IFN for 48 weeks. Clinical biochemical, and HBV serological indexes, as well as cytokines, were detected at baseline and every 12 weeks. Results: A total of 116 patients with CHB were enrolled in this study; 100 patients completed the 48-week treatment and follow-up, of whom 38 achieved serum HBeAg disappearance, 25 achieved HBeAg seroconversion, 37 showed HBsAg decreases ≥ 1 log ₁₀ IU/mL, 9 showed HBsAg disappearance, and 8 became HBsAb positive. The cytokine levels at baseline and during treatment were similar between the HBeAg disappearance group and non-disappearance group. The disappearance of HBeAg was independently associated with HBeAg levels at weeks 12 and 24, and with the HBeAg decline at week 24 ( P < 0.05). The HBsAg response was independently associated with HBsAg, the HBsAg decline, HBeAg, the HBeAg decline at week 12, and HBsAg at week 24 ( P< 0.05). Conclusion There was no significant correlation between the response to interferon (IFN) and cytokines during PEG-IFN treatment. The changes in virological markers predicted the response to IFN after 48 weeks.

In order to evaluate the composition and distribution characteristics of inorganic elements in Laminaria japonica, this study employed inductively coupled plasma mass spectrometry(ICP-MS) to detect the inorganic elements and used high performance liquid chromatography tandem ICP-MS(HPLC-ICP-MS) to determine the content of different arsenic species in L. japonica from diffe-rent origins. Micro X-ray fluorescence(Micro-XRF) was used to determine micro-area distribution of inorganic elements in L. japonica. The results showed that the average content of Mn, Fe, Sr, and Al was high, and that of As and Cr exceeded the limits of the national food safety standard. According to the results of HPLC-ICP-MS, arsenobetaine(AsB) was the main species of As contained in L. japonica. The more toxic inorganic arsenic accounts for a small proportion, whereas its content was 1-4 times of the limit in the national food safety standard. The results of Micro-XRF showed that As, Pb, Fe, Cu, Mn, and Ni were mainly distributed on the surface of L. japonica. Among them, As and Pb had a clear tendency to diffuse from the surface to the inside. The results of the study can provide a basis for the processing as well as the medicinal and edible safety evaluation of L. japonica.
