Abstract
The standardized training for public health physicians plays an important role in exploring the cultivation public health professionals and strengthening the construction of public health service providers. In 2018, the National Health Commission of China launched a pilot program of standardized training for public health physicians in 10 provinces. This paper clarifies the definition of the standardized training for public health physicians, systematically analyzes the status quo of the training in China and other countries, articulates the design and progress of the training in the perspective of Centers for Disease Control and Prevention, and makes some suggestions for the priorities of the pilot training program, so as to provide reference and basis for the better development of the standardized training for public health physicians in China in the future.

Abstract
OBJECTIVE To investigate the implementation of treat-to-target (T2T) and treatment satisfaction from Chinese rheumatologists' perspectives. METHODS This retrospective analysis of a cross-sectional database collected from rheumatologists and their adult patients with RA in China using Adelphi Real World Disease Specific Programme™ methodology. Multivariate logistic regression models were used to evaluate factors associated with T2T use, achievement of T2T goals, and physician treatment satisfaction. RESULTS Sixty physicians provided data for 600 patients, of whom 39.0% (234/600) were being treated using T2T, and 64.9% (366/564) had achieved their T2T goal. Physicians were satisfied with treatment in 74.3% (445/599) of patients. Patients with a higher pain score were more likely to be managed using T2T (odds ratio (OR) 1.25; p = 0.017), but less likely to have achieved the T2T goal (OR 0.76; p = 0.004). T2T use was more likely if patients had a longer time since diagnosis (> 2 vs ≤ 2 years; OR 1.61; p = 0.031) or received targeted synthetic or biologic disease-modifying antirheumatic drugs (tsDMARDs or bDMARDs; OR 6.90; p < 0.001). T2T goal achievement was more likely for patients with higher body mass index (≥ 24 vs < 24 kg/m2; OR 2.73; p = 0.001) or full-time employment (OR 2.11; p = 0.005). Physician treatment satisfaction was more likely if the T2T goal was achieved (OR 4.78; p < 0.001) or tsDMARDs or bDMARDs were used (OR 2.58; p = 0.017), and less likely if pain scores were higher (OR 0.79; p = 0.019). CONCLUSIONS T2T implementation in China is suboptimal. Our findings provide insight into T2T implementation and physician treatment satisfaction, supporting T2T use in Chinese RA clinical practice. Key Points • T2T implementation in China is currently suboptimal. • Patients with greater pain were more likely to be managed using T2T but were less likely to have achieved their T2T goals. • Physician treatment satisfaction was associated with T2T goal achievement.

Abstract
A questionnaire was used to investigate the emergency training needs of novel coronavirus pneumonia of disease prevention and control institutions in provinces, deputy provincial level regions and cities specifically designated in the state plan, and the effect evaluation of emergency training activities conducted by Chinese Center for Disease Control and Prevention (China CDC). The results showed that 67.4% of 47 disease prevention and control institutions (31/46) believed that the emergency training at the initial stage of the epidemic should be conducted as soon as possible, and the form of network training should be given priority. The training should focus on the urgently needed technologies such as epidemiological investigation, formulation and response of prevention and control strategies, laboratory testing, etc. The teaching materials should highlight pertinence and practicability and be presented in the form of electronic video. The average satisfaction score of the video training conducted by China CDC was (8.81±1.125) and the score of audio-video courseware was (8.97±0.893). The needs analysis and evaluation of novel coronavirus pneumonia prevention and control in disease prevention and control institutions could provide reference for the follow-up training and improve the emergency training management.

Abstract
To provide new ideas for clinical diagnosis and treatment of coronavirus disease 2019 (COVID-19), this study explore the expression level and prognostic value of platelet parameters in mild, moderate and severe COVID-19. This is a retrospective analysis. From January to May 2020, a total of 69 patients who were diagnosed with COVID-19 in the Third Central Hospital and the Jinnan Hospital (both situated in Tianjin) were enrolled in the disease group. According to the severity, these patients were divided into mild group (15 cases), moderate group (46 cases), and severe group (8 cases). In the same period, 70 non-infected patients were enrolled in control group. The level of white blood cell count (WBC), absolute neutrophil count (NEU#), absolute lymphocyte count (LY#), neutrophil-lymphocyte ratio (NLR), red blood cell count (RBC), hemoglobin (Hb), platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), and platelet-large contrast ratio (P-LCR) before and after treatment were analyzed. Binary logistic regression analysis is used to establish a mathematical model of the relationship between these indexes and the outcome of severe COVID-19 patients. The receiver operating characteristic(ROC) curve is used to further explore the prognosis value of MPV, P-LCR, NLR separately and jointly in COVID-19 patients. Compare to the control group, WBC and NE# increase (Z=-5.63, P<0.01;Z=-9.19,P<0.01) and LY# decrease (Z=-9.34, P<0.01) in the severe group; NLR increase with the aggravation of the disease, there is significant difference between groups (Z=17.61, P<0.01); PLT, PDW, MPV and P-LCR decrease with the aggravation of the disease, there is significant difference between groups (Z=9.47, P<0.01; Z=11.41, P<0.01; Z =16.76, P<0.01; Z=13.97, P<0.01). Binary logistic regression analysis shows MPV, P-LCR and NLR have predictive value for severe COVID-19 patients. There is a negative correlation between MPV, P-LCR and severe COVID-19 patients (OR=1.004, P=0.034; OR=1.097, P=0.046). There is a positive correlation between NLR and severe COVID-19 patients (OR=1.052, P=0.016). MPV and P-LCR of patients with good prognosis after treatment were significantly higher than those before treatment (Z=-6.47, P<0.01; Z=-5.36, P<0.01). NLR was significantly lower than that before treatment (Z=-8.13, P<0.01). MPV and P-LCR in poor prognosis group were significantly lower than those before treatment (Z=-9.46, P<0.01; Z=-6.81, P<0.01). NLR was significantly higher than that before treatment (Z=-3.24, P<0.01). There were significant differences between good and poor prognosis groups before and after treatment in MPV, P-LCR and NLR (P<0.01). Combination of these three indexes, ROC shows the AUC is 0.931, the sensitivity is 91.5%, the specificity is 94.1%, the positive predictive value is 88.9%, and the negative predictive value is 87.4%, which is better than any of these indexes separately. Changes in these parameters are closely related to clinical stage of COVID-19 patients. MPV, P-LCR and NLR are of great value in the prediction and prognosis of severe COVID-19 patients.

Abstract
Objective: To understand the attitudes and cognition of disease control and prevention professionals at provincial level on public health physician standardized training and provide evidence for the improvement of the standardized training and exploration of more effective training mode in China. Methods: By cluster sampling, 2 193 professionals at provincial centers for disease control and prevention (CDC) in 6 provinces, including Jiangsu and Guangdong, Shanxi and Hubei,Sichuan and Xinjiang were selected as the study subjects, the sample size was estimated to be 1 933 persons. Results: A total of 1 716 provincial-level CDC professionals were surveyed, the support rate to the standardized training was 70.7%(1 213/1 716). The level of support was negatively associated with the educational level of professionals and their specialty of public health and preventive medicine. Of 875 public health and preventive medicine professionals, 61.6%(318/516) of those with master's degree or above supported the standard training for public health physicians, which was lower than 73.1%(225/308) of those with bachelor's degree and 86.3%(44/51) of those with college degree or below. There were 14.9%(232/1 555) of the respondents suggested a two year training, and 60.4%(933/1 544) suggesting a field training mode. In terms of training content, 86.6%(1 355/1 564) suggesting "epidemiological survey and public health practice", and 76.7%(1 199/1 564) suggesting "basic theories and methodology". Conclusions: In general, the professionals of provincial CDC showed a relatively low interest in the standardized training for public health physicians and failed to reach a consensus. Besides, they were ill-informed about current training duration, method and content. Thas, the professionals at provincial CDC are suggested to be the key target-population whom should be mobilized during the training pilot period, especially the highly educated ones with relevant specialties of public health. It is suggested that public health physician standardized training should to be implemented in whole CDC system to reach full consensus based on its practical achievements and effects. It is also suggested to establish public health graduate medical education system in China.

Abstract
Objective: To understand the internship of students majoring in preventive medicine in 6 colleges and universities in China, and provide reference suggestions for the improvement of internship arrangement. Methods: By using the method of combined clustering and convenient sampling, the fifth grades students majoring in preventive medicine in six universities in the eastern, central and western China were surveyed by using questionnaires to collect the information of their attitudes (to) and suggestions for clinical and public health internships. Results: A total of 596 students were surveyed. In terms of the benefits of clinical internship and public health internship, students who thought that the internship was fruitful accounted for >88%, and more students thought that reform is needed in clinical internship compared with public health internship. In clinical internship, the students through that the time arrangement was not appropriate enough (95, 39.58%), the content should be more detailed and in-depth (73, 30.42%) and the content did not conform to the professional direction (54, 22.50%). In public health internship, the students thought that the time arrangement was not appropriate (77, 45.56%), the content should be more detailed and standardized (65, 38.46%) and the types of internship bases should be more diversified (20, 11.83%). Conclusions: The undergraduates majoring in preventive medicine felt to be benefited from clinical practice and public health internships and thought they are of necessity. At the same time, there are still many problems which needs to be improved in the two types of internships. It is necessary to make joint efforts from students, teachers, colleges and practice bases to promote the continuous improvement of undergraduate internship.

Abstract
To investigate the effects of selenium and light wavelengths on the growth of liquid-cultured Cordyceps militaris and the main active components' accumulation, culture conditions as selenium selenite concentrations and light of different wavelengths were studied. The results are: adenosine accumulation proved to be significantly selenium dependent (R(2) = 0.9403) and cordycepin contents were determined to be not significantly selenium dependent (R(2) = 0.3845) but significantly enhanced by selenium except for 20 ppm; there were significant differences in cordycepin contents, adenosine contents, and mycelium growth caused by light wavelengths: cordycepin, blue light > pink light > daylight, darkness, red light; adenosine, red light > pink light, darkness, daylight, blue light; and mycelium growth, red light > pink light, darkness, daylight > blue light. In conclusion, light wavelength had a significant influence on production of mycelia, adenosine, and cordycepin, so lightening wavelength should be changed according to target products in the liquid culture of C. militaris.

Abstract
OBJECTIVE To observe the effect of Yangjing Decoction (YJD) to promote ovulation and to explore its mechanism. METHODS The clinical effect of YJD in treating patients of functional non-ovulation and changes of gonadotropic hormone, sex hormone and diameter of main follicle before and after treatment were observed. In experimental study, the influence of YJD on monoamine neurotransmitter of hypothalamus, endorphin (beta-EOP), serum sex hormone, trace element, endometrium and histomorphology of ovary were observed. RESULTS In the 36 patients observed clinically, the ovulation rate was 61.1%, the serum contents of follicular stimulation hormone (FSH), luteinizing hormone (LH) and estradiol (E2) increased and the diameter of main follicle enlarged significantly after treatment (P < 0.01, P < 0.001). The experimental study showed that the totals of follicle at different levels, the corpus luteum and the proportion of superior follicle in ovary were improved obviously in the YJD group as compared with those in the control group. After YJD treatment the hypothalamus contents of monoamine neurotransmitter, including norepinephrine (NE) and dopamine (DA) increased, the 5-hydroxytryptamine (5-HT) 5-hydroxyindoleaceticacid (5-HIAA) and beta-EOP decreased significantly, and the NE/DA ratio and NE/5-HT ratio elevated obviously (P < 0.05, P < 0.001). The serum levels of E2, P and trace elements, including Zn, Cu and Fe increased significantly (P < 0.05, P < 0.01). CONCLUSION YJD is an effective recipe in promoting ovulation, the effect may be achieved through the multi-linked, multi-systemetic synthetic effect of hypothalamus, hypophysis and ovary, etc.

Abstract
The binding parameters of radiolabeled DAMGO (mu), DPDPE and pCl-DPDPE (delta) and 5 alpha, 7 alpha, 8 beta-N-methyl-N-[7-(1- pyrrolidinyl)-1-oxaspiro(4,5)dec-8-yl]benzeneacetamide (also known as U69593, kappa) and the affinity and selectivity profiles of various opioid agonists and antagonists at the three opioid receptor types were determined in membranes from brain cortex of rhesus monkey. Among the 10 opioids with established mu-selective actions, etonitazene inhibited the binding of [3H]DAMGO with a Ki of 0.02 nM (0.01 nM without sodium) and exhibited mu/delta and mu/kappa selectivities of 8800 and 11,650, respectively. DAMGO had a Ki of 1.23 nM and was about 500-fold more selective at mu receptors compared with delta and kappa sites. Other mu opioids with higher than 100-fold binding selectivity were fentanil and sufentanil. Highly selective delta opioids were DPDPE, deltorphin II and naltrindole. With the exception of N,N-diallyl-Tyr-Aib-Aib-Phe-Leu-OH, all investigated putative delta opioids bound to delta sites with low Kis, i.e., 0.04 nM, 0.13 nM and 1.4 nM for naltrindole, (+/-)-4-[(alpha-R*)-alpha-((2S*,5R*)-4-allyl-2,5-dimethyl-1-piperazinyl) -3- hydroxybenzyl]-N,N-diethylbenzamide and DPDPE, respectively. In this series, the displacement of [3H]pCl-DPDPE yielded results similar to those obtained with [3H]DPDPE. With nanomolar Kis of 0.70, 0.89, 0.25 and 0.06, respectively, the highest kappa selectivity was displayed by (trans)-(+/-)-3,4-dichloro-N-methyl- N-[2-(1-pyrrolidinyl)-cyclohexyl]benzeneacetamide and U69593, followed by dynorphin 1-13 and norbinaltorphimine.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Replantation of right hindlimbs in 76 immature rats was performed to study the factors affecting longitudinal growth of replanted extremities. There was a significant difference in tibia length between the replanted limb and the contralateral normal limb. The difference was significantly influenced by the ischemic interval (2 vs 4 hours), but not by suture method (intact vessels, vascular anastomosis with 10-0 nylon or 11-0 nylon). The replantation of immature extremities should be promptly undertaken because of the vulnerability of the epiphysis to ischemic insult.
