Objective:To figure out the clinical factors contributing to the oocytes utility rate (OUR) of high responders in in vitro fertilization (IVF)-embryo transfer treatment.Methods:OUR was defined by the number of usable embryos for transfer and (or) cryopreservation divided by the number of oocytes retrieved in a freeze-all cycle. The cycles with ≥15 eggs were included from January 2013 to December 2019. Those with OUR at the top 10% (Group A) and the bottom 10% (Group B) were picked and compared for patients′ characteristics, parameters relating to ovary stimulation and pregnant outcomes. Multifactorial logistic regression was applied to reveal the risk factors affecting OUR in them.Results:A total of 43 patients were included in Group A (OUR: 77.4%, 601/776) and 47 for Group B (OUR: 11.9%, 104/874). Previous IVF/intracytoplasmic sperm injection (ICSI; OR=0.10, 95% CI: 0.01-0.81) and endometriosis ( OR=0.16, 95% CI: 0.03-0.84) were negative factors for OUR ( P<0.05); dual suppression protocol ( OR=3.74, 95% CI: 1.06-26.86) and longer days of stimulation ( OR=3.24, 95% CI: 1.25-8.42) were protective factors in terms of ovarian stimulation ( P<0.05), on contrary to that, any decline of estradiol during the stimulation led to poorer OUR ( OR=0.16, 95% CI: 0.04-0.64). Although two groups had similar quantities of eggs and metaphase of meiosis Ⅱ (MⅡ) oocytes, distinguished cumulative clinical pregnancy rate and cumulative live birth rate were seen in Group A and group B respectively [95.3% (41/43) vs 40.4% (19/47) and 90.7% (39/43) vs 31.9% (15/47), all P<0.01]. Conclusions:High responders with attempted IVF/ICSI and endometriosis should be considered as risk factors for OUR. Over ovarian stimulation, dual suppression and a slightly longer stimulating duration could be tried; besides, estradiol decline should be prevented for a better OUR.

Objective:To investigate the effectiveness of stroke standardized patient (SP) combined with the subjective-objective-assessment-plan (SOAP) problem-based medical recording method in the practice teaching of Physiotherapy. Methods:A randomized controlled study was conducted, and 116 students from the undergraduate class of rehabilitation therapy were selected as research subjects. The students in the control group received traditional teaching, and those in the experimental group received the teaching model of stroke SP combined with the SOAP assessment recording method. The effectiveness of teaching was compared between the two groups at the end of the course. SPSS 24.0 was used for statistical analysis; the chi-square test was used for categorical data, and the paired samples t-test was used for comparison between groups. Results:Compared with the control group, the experimental group had significantly higher scores of practical skills (85.97±3.19 vs. 78.14±3.86, P<0.05), basic theoretical knowledge (86.00±3.74 vs. 84.07±5.24, P<0.05), and writing of rehabilitation treatment records (85.74±4.76 vs. 66.86±4.16, P<0.05). Compared with the control group, the experimental group had significantly higher scores of the dimensions of knowledge confidence (12.55±1.30 vs. 8.79±1.59, P<0.01), skill confidence (10.86±1.51 vs. 7.45±1.27, P<0.01), and communication confidence (11.69±1.71 vs. 7.83±1.44, P<0.01). Conclusion:In the practice teaching of Physiotherapy, stroke SP combined with the SOAP assessment recording method can effectively improve the professional quality and clinical thinking ability of students, enhance their professional confidence, make up for the shortcomings of traditional teaching methods, and promote the teaching reform of rehabilitation medicine.

Objective: To evaluate an assay permitting amplification of target 5′-untranslated region (5′-UTR) sequences directly from clinical specimens and distinction among serotypes of enterovirus (EV). Methods: A total of 518 rectal swabs and 148 nasal swabs tested positive by pan-enterovirus real-time PCR were collected. 5′-UTR and the viral protein 1 (VP1) gene fragments were amplified and sequenced separately for serotyping. The inconsistent samples by 5′-UTR and VP1 serotyping were further determined by using the serotype-specific RT-PCR. Results: A total of 553 (83.0%) samples were detected by 5′-UTR serotyping and 318 (47.7%) were detected by VP1 serotyping in all 666 positive specimens, and there was significant difference in the detection rates between two methods in rectal and nasal swabs (P<0.001). For the rectal swabs, the mainly detected serotypes were CoxA6 (217), CoxA16 (88), EVA71 (40), CoxA10 (28) and CoxA4 (27) by 5′-UTR serotyping. Compared with the VP1 serotyping, the sensitivity and specificity of 5′-UTR serotyping were 57.1%-100% and 67.4%-98.1% respectively, with varied consistence with serotypes (kappa value 0.214-0.283). For the nasal swabs, the most frequently detected serotype was EVD68, with the sensitivity of 100%, the specificity of 91.1%, and the poor consistence (kappa value 0.217). CoxA6, CoxA16, EVA71, CoxA10 and EVD68 were further confirmed by serotype-specific RT-PCR. Using VP1 serotyping combined with serotype-specific RT-PCR as a reference method , the effect of performance of 5′-UTR serotyping on diagnosis was increased. Conclusions The performances of 5′-UTR serotyping in enterovirus vary with serotypes. The application of 5′-UTR serotyping should be considered comprehensively according to the purpose of the study.

In order to form the expert consensus which researched on the comprehensive individualized protocol of Tuina therapy for Knee osteoarthritis, the preliminary protocol was summarized and formed by analyzing the interviews and published paper. And then the expert consensus method was applied for the protocols of Tuina therapy for KOA. After discussions, the consensus of three protocols according to the classification of KOA main symptomes was researched. In the protocols, 75％～80％ of the entries were considered as strong recommendation, and the others were weak recommended. Thus, it is believed that the comprehensive protocols for the treatment of KOA with different Tuina manipulations is feasible and reproducible after standardization.

Objective:To evaluate the methodological quality and evidence quality of outcome of the systematic reviews/meta analyses on traditional exercise for the improvement of cardiopulmonary function.Methods:By searching for PubMed, Cochrane Library, Web of Science, CNKI, Wanfang, VIP and CBM databases in Chinese or English, the Systematic Reviews/meta analysis of traditional exercises for improving cardiopulmonary function was conducted. The retrieval time was March 8th, 2020. The AMSTAR 2 scale was used to evaluate the methodological quality of the systematic review/meta-analysis that met the inclusion criteria. Since the included studies cannot reflect the overall effect of traditional exercises on improving cardiopulmonary function, and the methodological quality of systematic reviews was generally low, a secondary analysis of the RCT studies included in the systematic reviews was conducted. The methodological quality evaluation of the original RCT study adopted the Cochrane Reviewers’ Handbook Version 5.0.0 bias risk assessment method (Risk of Bias, ROB), and applied the Revman 5.3 software to merge the original RCT data. The GRADE system was used for evidence evaluation.Results:A total of 32 systematic reviews/meta analysis were included, and the AMSTAR2 scale indicated that only one of the 32 systematic reviews/meta included was of high-quality, 1 was of low-quality, and the others were of extremely low quality. A total of 57 RCTs were included in the 32 systematic reviews for bias risk assessment and data consolidation. GRADE evidence quality evaluation showed that 14 evidences were of medium quality, 26 evidences were of low quality, and 5 evidences were of extremely low quality.Conclusions:Traditional exercises can improve cardiopulmonary function, but with low evidence quality. Thus, clinicians should make clinical decisions based on conditions.

Based on the resutls of literature review and interviews of experts, two rounds of Delphi surveys were conducted. The mean, importance ratio, coefficient of variation and coordination coefficient were used for assessment of survey from multiple perspectives, and finally form a framework model of factors affecting the efficacy of Tuina therapy. A total of 37 experts were selected for questionnaire surveys, the positive coefficients of experts' participatation in the first round and second round were 92.5% and 80.0%, respectively. The overall coordination coefficient in the second round is 0.68. The items were included into the consensus meeting if the importance ratio of items were equal to and more than 80%. After the expert consensus meeting, 22 items were included to form a framework model of factors affecting the efficacy of Tuina therapy, and summarized as 5 major influencing factors, including diagnostic factors, treatment factors, prognostic factors, patient factors, and doctor-patient communication. This framework can guide and help young Tuina practitioners to improve clinical efficacy. It is also clearly pointed out that the effect of Tuina for pain is not only related to disease diagnosis or manipulation, but also related to home exercise, health care, and doctor-patient communication.

Tuina (Chinese massage) is an important part of Traditional Chinese Medicine. It is a simple and inexpensive technique, and has shown effectiveness for muscle and bone diseases, visceral diseases, gynecological diseases, and common diseases in children. This paper aims to analyze the factors influencing the effects of Tuina. The factors included the aspects of diagnosis, treatment, prognosis, patient factors and doctor-patient communication. During the treatment of Tuina, doctors should carry out good doctor-patient communication, properly evaluate and exam patients, and clarify diagnosis, take appropriate Tuina techniques according to the patients' constitution, health condition, and comorbidity. Only in such way, could Tuina achieve effectiveness and safety.

Objective: By analyzing the clinical features of patients with dengue fever in Guangzhou from 2015 to 2018 to furnish the reference evidences for the diagnoses and treatment of dengue fever. Methods: A total of 406 dengue fever patients admitted to Zhujiang hospital during 2015 to 2018 were analyzed for the clinical manifestations and laboratory examination results, retrospectively. ZIKV, CHIKV and the serotypes of DENV were detected in some samples. Results: DENV serotypes were tested in 96 dengue fever patients and 69 cases were positive. Among them, 58 cases (84.1%) were DENV-1, 10 cases (14.5%) were DENV-2, 1 case (1.5%) was DENV-3, DENV-4 was negative and no co-infection with different serotypes of dengue virus was found. Of all the 406 patients, 371 (91.4%) were diagnosed as dengue fever and 35 (8.6%) were severe cases. The most common manifestations included fever, weakness and rash. Significantly higher incidence (P<0.05) of bleeding, coughing, expectoration, vomiting and abdominal pain were found in severe dengue fever. The most common laboratory findings were leucopenia and thrombocytopenia. Significant increase(P<0.05) of total bilirubin, aspartate aminotransferase, serum creatinine, high-sensitivity C-reactive protein and procalcitonin were observed. ZIKV and CHIKV nucleic acids were tested in 380 dengue fever patients and the result were negative for both. Conclusions The incidence of dengue fever in Guangzhou increased in 2017 and 2018.Most cases of dengue fever were mild and DENV-1 was the dominant serotype.
