Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

Objective:To analyze the competence assessment examinations of registered dietitians in China during 2017-2021 to inform the training of dietetic professionals.Methods:A systematic review was conducted about the composition and changing trends of examination participants during 2017-2021. Participants were divided into subgroups based on gender, age, education, professional background and affiliations and the qualification rate was compared across different subgroups.Results:The number of examination participants showed an increasing trend overall, with the majority being females and aged 26-35 years. The ratio of participants with bachelor's: master's: doctor's degree was about 15: 9: 1. The proportion of participants majoring in nutrition science decreased from 32.1% to 20.3%, while that of participants majoring in other medical and food sciences increased. Among participants from healthcare institutions, a decreasing proportion of participants were with a major in nutrition science, while this proportion among participants from companies were stable at 38.8% to 50.2%. The average qualification rate was 35.7%, showing no significant differences among different gender and age groups. But the qualification rate varied significantly across subgroups with different education level, professional background, and affiliations ( P < 0.05). Subgroups with more advanced degrees showed higher qualification rate and the best rate was observed in the subgroups with professional background in nutrition science and from nutrition-related institutions. Conclusion:The training of dietetic professionals in China should be improved, lifelong learning should be promoted in nutrition practitioners, and the sustainable development of dietitians should be impelled.

Objective To further strengthen the management of radiological health technical service institutions, standardize their technical service behaviors, and explore the supervision countermeasures for radiological health and technical service institutions. Methods The radiological health technical service institutions status questionnaires s were designed to survey the basic situation, professionals and technical personnel, the equipment configuration, testing items and workload of service institutions. Results By the end of 2019, there were 23 radiological health technical service institutions in Hebei province, including 8 disease control and occupational prevention institutions (accounting for 34.8%) and 15 third-party institutions (accounting for 65.2%); The distribution of regional agencies were unbalanced; There were 223 professional and technical personnel, of which 29.6% were senior technical professionals, 29.6% were intermediate technical professionals and 40.8% were other professionals.58.8% had a bachelor's degree or above, and 41.2% had a college degree or below; The majors of professionals were relatively scattered, with only 6.44% of radiological health, 5.15% of physics-related majors, and 51.07% of medical-related majors. Other majors involve chemical pharmacy, environmental engineering, public relations planning, food, English, accounting and other majors.The professional technical responsible person had no part-time job;. The institution were totally equipped with 308 sets of radiation protection detectors and 172 sets of phantoms, basically in line with the configuration requirements; All quality control system documents such as quality management manuals, procedural documents, operating procedures, and work instructions have been established; All test items applied by laboratory measurement certification have passed;Conclusion The CDC institutions were gradually shrinking, the private institutions were gradually increasing and the nature of the institutions was gradually diversified.The allocation of regional resources was unbalanced.It is suggestedto strengthen the training on the theoretical basis and professional skills of professionals in testing and evaluation. Increasing on-site practical training is a more important and effective way.It is recommended to strengthen the training of basic-level health administrative departments and supervisory agencies and improvethe sense of responsibility of supervisors.

Objective: To standardize the occupational health management of radiation workers and raise the management level and technical content for the supervision of occupational health of radiation workers. Methods: The information system for radiation worker passbook was established and applied in Hebei province for practice. Results: Until December 2018, 4 339 passbooks have been issued to radiation workers from 140 medical institutions. Through the establishment and operation of the radiation worker passbook information system, the basic information and distribution characteristics of the provincial registered medical institutions and their radiation workers in Hebei province were obtained. The efficiency of the examination and approval and issuance of radiation worker certificates by the health administrative departments was improved by reducing the intermediate procedure. Conclusions Data are obtained and provided for the discussion of electronic card management of occupational health of radiation workers, real-time query of information such as medical institutions of radiation workers, education and training, individual dose monitoring, occupational health examinations, and diagnosis and identification of occupational radiological diseases. Reference basis is provided for health administrative departments to carry out radiation worker supervision.

Objective To acquire the basic information on diagnostic radiology and radiotherapy institutions and the frequency of medical radiation of Hebei province in 2016.Methods A survey was made using questionnaires for basic information on medical X-ray diagnosis,interventional radiology,radiotherapy and clinical nuclear medicine.Values of frequencies were derived for each type of medical X-ray procedure by dividing the total population.Results In 2016 there were 2 951 institutions at province level and 6 966 pieces of equipment involved in diagnostic radiology and radiotherapy treatments.Frequency values were estimated to be 379.25 examinations per 1 000 population in medical X-ay diagnosis,2.31 per 1 000 in interventional radiology,0.55 per 1 000 in radiotherapy and 1.65 per 1 000 in clinical nuclear medicine.The frequency for CT examination was 136.39 per 1 000,accounting for 36％ of the total frequencies in the province,with average annual growth rate of 12.4％.The highest value of frequency in clinical nuclear medicine was from Shijiazhuang among all types of medical procedures in different regions,11 times higher than the lowest value found in Hengshui city.Although the number of tertiary hospitals only accounted for 2.3％ of the total number of institutions,they contributed 25.5％,by examination number,of the medical X-ray diagnosis and 35.3％ of the CT examination.Interventional radiology and radiotherapy contributed more than 70％ of the total frequencies in the province,and clinical nuclear medicine was as high as 97.7％.Conclusions The basic information on diagnostic radiology and radiotherapy institutions and the frequency of medical procedures in Hebei in 2016 have been preliminarily made clear.Medical exposure could maintain a long-term growth trend.The frequency distribution of medical procedures in various regions and medical institutions is highly unbalanced.It is desirable to enhance the macroeconomic regulation and the management of medical radiation protection in order to rationally perform all types of diagnostic radiology and radiotherapy treatments to protect the health and safety of the patients and the examined individuals,and to promote the sustainable development of the health care services.

Objective: To explore the impact of socioeconomic status on minority college students’ healthy sports behaviors, and to provide guidance for improving physical fitness among minority college students. Methods: Binary Logistic regression and path analysis were used to analyze the path and effect of socioeconomic status on minority college students’ healthy sports behaviors, controlled for health status, academic pressure, sports attitude, sports venues, sports skills and health knowledge. Results: Socioeconomic status was positively associated with students’ healthy sports behaviors (OR>1). With the potential variables controlled, the odds of participating in healthy sports activity among urban students, sophomores and female students was 2.10, 2.60 and 0.59 times higher than that of rural students, freshman and male students. Path analysis showed that the direct effect of socio-economic status on minority college students’ healthy sports behavior was 0.07, the indirect effect was 0.16, and the total effect was 0.23. Conclusion Socioeconomic status shows direct and indirect effect on healthy sports behaviors among college students, with the indirect effect being larger than direct effect. Apart from socioeconomic status, physical fitness education, as well as creating and maintaining a good physical exercise environment by schools and society should be encouraged to facilitate college students establishing healthy sports behaviors.

A rapid, sensitive, label-free and separation-free analytical method for determination of melamine ( MA) was developed based on surface enhanced Raman scattering ( SERS ) effect of gold nanoparticles. Through tri-sodium citrate reduction method, gold nanoparticles with average diameter of 30 nm were obtained. The melamine detection platform was constructed after self-assembling 4-mercapto phenylboronic acid (4-MPBA) on the surface of gold nanoparticles through Au S covalent bond. When MA existed in solution, 4-MPBA functionalized gold nanoparticles would aggregate because of strong hydrogen bond interaction between MA and 4-MPBA. Moreover, following increase of the concentration of MA, gold nanoparticles would aggregate more intensively and form more hot spots. As a result, Raman signal of 4-MPBA and MA was enhanced greatly. The characteristic Raman peaks of 4-MPBA and MA respectively located at 1076 cm-1 and 715 cm-1 . Hence, the qualitative and quantitative detection for MA were realized based on the ratio value of I715 cm-1 to I1076 cm-1 . The linear range of MA detection was 0 . 1 μmol/L-1. 5 μmol/L. The limit of detection (LOD) reached 0. 02 μmol/L in terms of three times signal to noise.

Objective To evaluate the surgical outcome of cystic vestibular schwannoma patients with fluid-level imaging by MRI.Methods Forty-five patients of cystic vestibular schwannoma were enrolled and divided into fluid-level (n =24) group and non-fluid-level (n =21) group by MRI.The incidence of peritumoral adhesion,incidence of complete tumor removal and postoperative facial nerve function of the two groups were recorded.Results The incidence of peritumoral adhesion in fluid-level and non-fluid-level group were 70.8％ (17/24) and 28.6％ (6/21),and the difference was significant (x2 =8.010,P ＜ 0.05).The incidence of complete tumor removal were 45.8％ (11/24) and 76.2％ (16/21) in fluid-level and non-fluid-level group,which showed significant differences between groups (x2 =4.30 ; P ＜ 0.05).Patients of House-Brackmann grade Ⅰ-Ⅲ in fluid-level group at discharge and one year after operation,were 62.5％ (15/24) and 50.0％ (8/16),and 81.0％ (17/21) and 83.3％ (15/18) in non-fluid-level group.The was significant difference at one year after operation (P ＜ 0.05) in terms of patients of House-Brackmann grade Ⅰ-Ⅲ.Conclusion The cystic vestibular schwannoma patients with fluid level have more frequency to adhere to surrounding neurovascular structures and less favorable surgical outcome.These findings may be useful in predicting surgical outcome and making surgical strategy preoperatively.

BACKGROUND: Transforming growth factor beta (TGF-β) has an important role in tendon healing and adhesion formation.Inhibiting TGF-β and its receptor expression may prevent adhesions after tendon open.OBJECTIVE: To study the effects of mannose-6-phosphate, a natural inhibitor of TGF-β, on TGF-β and its receptor production in tendon sheath fibroblasts, epitenon tenocytes, and endotenon tenocytes of rabbit flexor toes.METHODS: Tendon sheath fibroblasts, epitenon tenocytes, and endotenon tenocytes were isolated from rabbit flexor tendon and cultured separately. All these cells were divided into 2 groups at random, experiment group supplemented with mannose-6-phosphate and control group without mannose-6-phosphate. The expression of TGF-β and TGF-β receptor was quantified with enzyme-linked immunosorbent assay. The expression of TGF-β1 was also assessed with in situ hybridization and immunohistochemistry.RESULTS AND CONCLUSION: The expression of TGF-β and TGF-β receptor in experiment group was significantly lower than that in control group (P ＜ 0.05). In experimental group, the positive expression of TGF-β1 mRNA and the expression level of intracellular TGF-β1 mRNA in all tendon cells demonstrated significantly lower than those in the control group (P ＜ 0.05).Immunohistochemical staining showed expression of TGF-β1 were significantly lower in all three types of tendon cell cultured with mannose-6-phosphate.

Objective To study the similarities and differences of personality in patients with body-dysmorphic disorder(BDD),obsessive-compulsive disorder(OCD) and ordinary person.As well as to provide information for clinical therapy. Methods All BDD patients( n =29),OCD controls( n =30) and normal controls( n =30) completed Self Rating Scale of Body Image (SRSBI) and Minnesota Multiphasic Personality Inventory (MMPI). Results Ten clinical scales score of MMPI in BDD were found significant higher than normal controls which including hypochondriasis,depression,hysteria, psychopathic deviate, masculinity-femininity, paranoia,psychasthenia,schizophrenia,and social introversion.Four clinical scales[(68.18±8.70),(65.44±8.73),(61.39±9.37),(60.70±12.88)] were significant higher than OCD controls[(61.09±13.29),(58.82±10.26 ),(56.23±9.58),(50.03±12.63)] which including psychopathic deviate,psychasthenia,schiaophrenia and social introversion( P ＜0.05). But hysteria scale was significant lower than OCD controls( P ＜0.01). Conclusion BDD patients have abnormal personality which is more significant than OCD patients. Significant abnormal personality are likely the psychopathology of BDD from which the clinic symptom produced.
