Objective:To identify enolase,47 kD allergen,from Litopenaeus vannamei by Mass spectrometry. Methods: The proteins were extracted from Litopenaeus vannamei tissue with acetone precipitation method. The protein components were analyzed by SDS-PAGE and Western blot. By using Matrix-Assisted Laser Desorption/Ionization time of flight mass spectrometry ( MALDI-TOF/TOF-MS) ,the 47 kD allergen from Litopenaeus vannamei was identified as enolase. Results:By SDS-PAGE,we proved that the native protein components from Litopenaeus vannamei were completely. According to the Western blot result more than 14 components could react with the positive serum. MALDI-TOF/TOF analysis results showed that the suspected proteins were enolase. A sensitization frequency was 55%. Conclusion:Enolase was identified as a new allergen of Litopenaeus vannamei.

Objective:To explore the present situation of medical students' professionalism cognition and provide reference for medical personnel training and medical education.Methods:A cross-sectional survey was conducted on medical students among 2 affiliated hospitals of a medical university in H province by cluster sampling. Exploratory factor analysis and reliability and validity test were carried out and a descriptive analysis of the present situation of professionalism was conducted by SPSS 20.0. Amos21.0 software was used for a confirmatory factor analysis on the samples.Results:The measurement scale had good reliability and validity, and the Cronbach alpha coefficient of the scale was 0.901. The average professionalism score of the medical students was about 80 points. The score of "physical and mental status and self-development ability" was the highest (83.65 points), and the lowest score was "academic ability" (72.21 points). There was a little difference in the professionalism cognition between the two hospitals, with significant differences between the dimension "respect and care" and "responsibility".Conclusion:This study has initially formed a medical professionalism measurement scale with good reliability and validity. The professionalism of medical students in the 2 affiliated hospitals of a medical school in Province H is in good condition as a whole. In the future, medical education should pay more attention to the combination of basic professional knowledge and clinical practice of medical students, and change the training model of medical students in order to improve the academic ability of medical students and medical students' overall cognition of professionalism.

With the rapid development of nanotechnology, accurate personalized treatments for tumor have attracted more attention to increase the therapeutic effects and reduce the side effects. The emerging theranostic systems incorporating different therapeutic and diagnostic imaging capabilities have become a new research hotspot. Magnetic iron oxide nanoparticles(IONP)have been widely used in theranostic systems due to their unique imaging properties, stable thermal performance, excellent biocompatibility and admirable surface modifiability. In this review, we analyzed the advantages of IONP in the diagnosis and the treatment of tumor, and detailedly introduced the relevant strategies and latest research progress, including magnetic resonance imaging(MRI), photothermal therapy, magnetic hyperthermia, and magnetic targeted drug delivery, etc. Finally, the potential application of IONP in the clinical tumor theranostics was proposed.

OBJECTIVEThis retrospective study is to analyze the outcomes of cN0 stage tongue squamous cell carcinoma and to discuss a reasonable neck management for these cases.

METHODSTotally 132 cases of cN0 stage tongue squamous cell carcinomas were included. Seventy-one cases were performed neck dissection(group ND), 61 cases were under wait-and-see (group WS). The clinical, pathological and follow up data of two groups were analyzed.

RESULTSThe cumulative three-year-survival between group ND and group WS were 87.3% and 83.4% respectively. In group ND, the survival of T1 and T2 cases were 89.3% and 83.3% respectively, while 89.6% and 58.3% in WS. For T2b cases which the size was larger than 3.0 cm, the survival of group WS was greatly lower than that of group ND. Both in ND and WS groups. The pathologically poor differentiation cases got poor survival than middle and well cases.

CONCLUSIONThe wait-and-see policy is recommanded for T1 stage cN0 tongue squamous cell carcinoma. For T2 cases that the tumor size is smaller than 3.0 cm, the wait-and-see is also reasonable, while the neck dissection should be considered in cases of poor differentiation. For large T2 cases, the selective neck dissection should be performed.

Objective: To explore the ways to build a team of professional drug inspectors in Hubei province in oder to improve the quality and effectiveness of drug inspections in our province, reduce the risk of supervision, and ensure the safety of people's drug use. Methods: The requirements of national regulations and policies for the inspectors were interpreted, the construction system of profes-sional drug inspectors in Shanghai drug review and verification center was selected as comparison, the current situation and existing problems of the construction of drug inspectors in our province were analyzed, and the construction methods of professional inspectors in Hubei province were found out. Results: On the basis of the existing team of drug inspectors, a standardized system for selection, training, evaluation and grading of drug inspectors should be established, and the establishment of a team of professional drug inspec-tors in our province should be gradually completed. Conclusion: Our province can gradually establish a team of professional drug in-spectors, firstly from the current "main part-time assisted by full-time" to " lay equal stress on part-time and full-time", and then to"main full-time assisted by part-time", till the final realization of all professional drug inspectors.

Objective:To evaluate the clinical effectiveness and safety of Jiuwei-Zhuhuang San plus amoxilcillin sodium and sulbactam sodium in the treatment of bacterial pneumonia in children. Methods:A total of 120 patients with bacterial pneumonia in children from 1 year to 14 years old were randomly divided into the study group ( n=90) and the control group ( n=30) with ratio 3 to 1, the random sequence created by SAS software. Both groups were treated with amoxilcillin sodium for basic treatment, the observation group was treated with Jiuwei-Zhuhuang San. Both groups were treated for 1 week and followed up for 1 week. The cough frequency, clinical effective rate, symptoms and signs score, Traditonal Chinese medicine (TCM) pattern scores and adverse event rate were observed. Results:Eighteen cases were dropped and eliminated in the observation group, and 4 cases were dropped and eliminated in the control group, so 72 of observation group and 26 of control group were analyzed. After treatment, the clinical effective rate of the observation group was 27.8% (20/72), and the control group was 0% (0/26), where the difference was significant ( χ2=7.445, P=0.006). The difference of TCM syndrome score before and after treatment in the observation group (-16.8 ± 8.2 vs. -11.0 ± 5.8, t=-3.858) was lower than that of the control group ( P<0.01). There was significant difference between the two groups ( Z=-2.347, P= 0.019) in the TCM syndrome. The cough frequency of the observation group was 41.7% (30/72), and the control group was 26.9% (7/26). There wasn’t any significant differences in the cough frequency between two groups ( P>0.05). There was no statistical difference in symptoms and signs score or adverse event rate between two groups ( P>0.05). Conclusion:On the basis of amoxicillin sodium and sulbactam sodium, combined use of Jiuwei-Zhuhuang San can improve the clinical effectiveness of children with bacterial pneumonia.

Objective:To compare the efficacy and safety of Dienogest(DNG)with other drugs in non-surgi-cal pharmacologic treatment and long-term management of drugs after conservative surgery for endometriosis(EMT).Methods:We searched PubMed,Embase,Medline,Google Scholar,Cochrane Library,China National Knowledge Infrastructure,Wanfang,and Weipu databases from the establishment of the database until December 31,2023 for relevant literature on EMT pharmacotherapy.Meta-analysis was performed using Stata 18.0 software to assess the efficacy of DNG,gonadotropin-releasing hormone agonist(GnRH-a),compound short-acting oral contraceptive(COC)and levonorgestrel intrauterine sustained-release system(LNG-IUS)in reducing the diameter of ovarian endometrioma(OMA),relieving pelvic pain and preventing EMT postoperative recurrence in EMT pa-tients after non-surgical drug treatment and conservative surgery,as well as the adverse reactions of drugs.Re-sults:①During non-surgical medication treatment of EMT,there was no statistically significant difference(P＞0.05)between DNG and GnRH-a in reducing OMA diameter and relieving pelvic pain.Compared with COC,DNG was superior to COC in reducing the diameter of OMA(WMD 10.44 mm,P=0.017)and relieving pelvic pain(WMD 12.20 mm,P＜0.001).②During long-term medication management after conservative EMT surger-y:there was no statistically significant difference(P＞0.05)between DNG,GnRH-a,COC and LNG-IUS in re-ducing postoperative recurrence and controlling pelvic pain significant(P＞0.05).③Adverse drug reactions:com-pared with GnRH-a,DNG had a reduced risk of bone loss(bone density WMD2.78 g/cm3,P=0.038),hot fla-shes(OR 0.07,P＜0.001),and an increased risk of irregular vaginal bleeding(OR 19.10,P＜0.001);com-pared with COC,the risk of weight gain,mood abnormalities,and breast tenderness,nausea and vomiting,and sleep disorders in DNG were reduced(OR＜1,P＜0.05);compared with LNG-IUS,the risk of abnormalities of mood in DNG was increased(OR 9.87,P=0.033).Conclusions:DNG treatment is more effective than COC in non-surgical drug therapy for EMT.When supplemental medication was given after conservative EMT surgery,DNG,like other drugs,can effectively prevent postoperative recurrence and control pelvic pain.The safety of DNG is superior to GnRH-a and COC,slightly inferior to LNG-IUS.
