OBJECTIVETo observe the effect of acupuncture combined physical training and relearning on stroke patients.

METHODSA multi-center, randomized controlled trial design was adopted. A total of 364 stroke patients were recruited and randomly assigned to the experimental group (184 cases) and the control group (180 cases). Patients in the experimental group received acupuncture combined with physical training and relearning, while those in the control group only received physical training and relearning. All received four weeks of treatment. Effects on Fugl-Meyer motor function, neurological impairment, activities of daily living difference were compared before treatment, after treatment, 2 and 5 months after follow-ups between the two groups.

RESULTSTotally 353 patients completed this trial, 179 in the experimental group and 174 in the control group. (1) compared with before treatment, brief Fugl-Meyer motor functions scores and FIM scored obviously increased, and scores for neurological impairment obviously decreased in the two group. Besides, the increment of brief Fugl-Meyer motor functions scores and FIM scores was obviously higher in the experimental group than in the control group at month 2 and 5 of follow-ups; scores for neurological impairment was obviously lower in the experimental group than in the control group. The increment of FIM scores was obviously higher in the experimental group than in the control group at month 5 of follow-ups (P < 0.05, P < 0.01). (2) There was statistical difference in inter-group comparison of total Fugl-Meyer motor functions scores and FIM scores, or scores for neurological impairment (P < 0.01). The improvement of Fugl-Meyer motor functions grading and neurological impairment grading was obviously superior in the experimental group at month 2 and 5 of follow-ups. The distribution of FIM grading was also better in the experimental group at month 5 of follow-ups (P < 0.05, P < 0. 01).

CONCLUSIONSBoth acupuncture combined exercise training and relearning and physical training and relearning could effectively promote the rehabilitation of stroke patients, reduce their neurological impairment degrees, improve motor functions and independent capacities. Better long-term efficacy could be obtained by acupuncture combined exercise training and relearning.

Under the guidance of the teaching goal management philosophy, process and result quality of teaching task and its implementation are transformed into the goal scores of teachers, clinical departments and teaching research departments. Teaching administration departments regularly conduct tar-geted work inspection, collect relevant data for statistical analysis, feedback and request the corresponding improvement. In order to improve the efficiency of clinical teaching management and realize the seamless connection between clinical teaching management and clinical teaching, by combing the associations of clinical teaching, learning, management, information technology is used to establish the corresponding teaching work module. Meanwhile, by data analysis of clinical first-line teaching tasks and implementation process, the real-time information input and the summary statistics feedback output system of teaching, learning and management is established,so that the synchronization of teaching and teaching quality moni-toring can be realized, teaching documents are normalized and paperless office can be achieved.

Objective To evaluate the long-term effectiveness of the first set 8 methadone maintenance treatment (MMT) clinics in China. Methods Repeated cross-sectional surveys were conducted on the first month after the enrollment and 5 years later,among drug users who received MMT,using a standard questionnaire.Data on demographic characteristics,HIV-related high-risk bchaviors,criminal records associatcd with drug use and related family/social functions were collected and analyzed.Results There were 252 and 195 participants being interviewed at the baseline and the 5-year surveys,respectively,.Of them,66 participants were involved in both surveys.There was no significant differences on factors as ethnicity,level of education,working status,marital status and living status (P＞0.05) between the baselinc and the 5-year surveys.Compared with data from the baseline survey,participants' behavior on drug abuse (100.0％ vs.24.1％,P＜0.001 ),needle sharing behavior ( 19.4％ vs.0.0％,P ＜ 0.001 ),and exchanging sex for drugs ( 34.5 ％ vs.0.0％,P＜0.001 ) had significant decreases at the 5-year survey.Rates on condom use ( 10.6％ vs.25.0％,P=0.004),and having jobs (27.8％ vs.47.7％,P＜0.001 ) had been improved significantly,while self-reported criminal cases related to drug use (15.1％ vs.1.5％,P＜0.001) and the contacts with drug users (88.9％ vs.31.3％,P＜0.001) had been significantly reduced after joining the MMT program.Conclusion MMT could play an active role in reducing the HIV-related high-risk behaviors,criminal cases associated with drug abuse as well as enhancing the family and social functions of the MMT patients.Providing high quality service to the MMT clinic and trying to keep the drug users stick to the program remain difficult.It was also important to improve the training programs for staff working at the MMT clinics.

Objective: To understand the current status of diagnosis and treatment of chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL) among hematologists, oncologists, and lymphoma physicians from hospitals of different levels in China. Methods: This multicenter questionnaire survey was conducted from March 2021 to July 2021 and included 1,000 eligible physicians. A combination of face-to-face interviews and online questionnaire surveys was used. A standardized questionnaire regarding the composition of patients treated for CLL/SLL, disease diagnosis and prognosis evaluation, concomitant diseases, organ function evaluation, treatment selection, and Bruton tyrosine kinase (BTK) inhibitor was used. Results: ①The interviewed physicians stated that the proportion of male patients treated for CLL/SLL is higher than that of females, and the age is mainly concentrated in 61-70 years old. ②Most of the interviewed physicians conducted tests, such as bone marrow biopsies and immunohistochemistry, for patient diagnosis, in addition to the blood test. ③Only 13.7% of the interviewed physicians fully grasped the initial treatment indications recommended by the existing guidelines. ④In terms of cognition of high-risk prognostic factors, physicians' knowledge of unmutated immunoglobulin heavy-chain variable and 11q- is far inferior to that of TP53 mutation and complex karyotype, which are two high-risk prognostic factors, and only 17.1% of the interviewed physicians fully mastered CLL International Prognostic Index scoring system. ⑤Among the first-line treatment strategy, BTK inhibitors are used for different types of patients, and physicians have formed a certain understanding that BTK inhibitors should be preferentially used in patients with high-risk factors and elderly patients, but the actual use of BTK inhibitors in different types of patients is not high (31.6%-46.0%). ⑥BTK inhibitors at a reduced dose in actual clinical treatment were used by 69.0% of the physicians, and 66.8% of the physicians had interrupted the BTK inhibitor for >12 days in actual clinical treatment. The use of BTK inhibitors is reduced or interrupted mainly because of adverse reactions, such as atrial fibrillation, severe bone marrow suppression, hemorrhage, and pulmonary infection, as well as patients' payment capacity and effective disease progression control. ⑦Some differences were found in the perceptions and behaviors of hematologists and oncologists regarding the prognostic assessment of CLL/SLL, the choice of treatment options, the clinical use of BTK inhibitors, etc. Conclusion: At present, a gap remains between the diagnosis and treatment of CLL/SLL among Chinese physicians compared with the recommendations in the guidelines regarding the diagnostic criteria, treatment indications, prognosis assessment, accompanying disease assessment, treatment strategy selection, and rational BTK inhibitor use, especially the proportion of dose reduction or BTK inhibitor discontinuation due to high adverse events.
