Implementation science (IS) aims to systematically analyze and address the real-world gaps from evidence to practice and the influencing factors of the context. It is necessary to carry out qualitative research to gather relevant implementation outcomes. Nevertheless, traditional qualitative analysis has issues such as consuming a great deal of time and energy, and it is unable to promptly provide the crucial data required for implementation science research. The Rapid Qualitative Analysis (RQA) method, through semi-structured interviews and the adoption of techniques such as immediate data condensation and matrix analysis, can effectively shorten the cycle of qualitative data collection and data processing. RQA can promptly identify social determinants of health such as structural barriers, facilitators, and the behavioral characteristics of target groups. It provides a real-time basis for public health decision-making, the interpretation of complex social phenomena, and the process and effectiveness evaluation of research projects. Although RQA is difficult to conduct in-depth theoretical analysis based on grounded theory, its efficiency and flexibility make it the preferred tool for large-scale and time-sensitive research. Thus, it has been widely applied in implementation science research. This paper sorts out the core concepts and commonly used technical methods of RQA, as well as the differences between RQA and traditional qualitative analysis. It also explores the applications of RQA in intervention optimization, process evaluation, and implementation outcome evaluation. By integrating specific cases, this paper clarifies its application value in the field of implementation science. In the future, it is advisable to explore the integration of RQA with technologies such as artificial intelligence and big data, in order to bridge the gap between the transformation of scientific research achievements into practice. Under circumstances of limited resources or tight time constraints, RQA can be used to efficiently conduct implementation science research, providing convenient and scientific methodological and technical support for accelerating evidence-based practice.

Osteoarthritis (OA) causes chronic pain that significantly impairs quality of life, with current treatments often proving insufficient and accompanied by adverse effects. Recent research has identified the dorsal root ganglion (DRG) and its resident macrophages as crucial mediators of chronic OA pain through neuroinflammation driven by macrophage polarization. We present a novel injectable thermo-sensitive hydrogel system, KAF@PLEL, designed to deliver an anti-inflammatory peptide (KAF) specifically to the DRG. This biodegradable hydrogel enables sustained KAF release, promoting the reprogramming of DRG macrophages from pro-inflammatory to anti-inflammatory phenotypes. Through comprehensive in vitro and in vivo studies, we evaluated the hydrogel's biocompatibility, effects on macrophage polarization, and therapeutic efficacy in chronic OA pain management. The system demonstrated significant capabilities in preserving macrophage mitochondrial function, suppressing neuroinflammation, alleviating chronic OA pain, reducing cartilage degradation, and improving motor function in OA rat models. The sustained-release properties of KAF@PLEL enabled prolonged therapeutic effects while minimizing systemic exposure and side effects. These findings suggest that KAF@PLEL represents a promising therapeutic approach for improving outcomes in OA patients through targeted, sustained treatment.

ObjectiveTo adapt the Stanford Expectations of Treatment Scale（SETS） into Chinese（C-SETS） and test the feasibility， validity and reliability of its application in patients with diarrhea-predominant irritable bowel syndrome（IBS-D） with liver-constraint and spleen-deficiency syndrome treated with traditional Chinese medicine（TCM）. MethodsWe obtained authorisation from the developer of the SETS， and followed the principle of "two-way translation" to translate the SETS by literal translation and back translation to form the C-SETS. Ninety-six IBS-D patients with liver-constraint and spleen-deficiency syndrome were enrolled as respondents and filled out C-SETS before receiving treatment； the feasibility was assessed by the recall rate， completion rate and the duration of filling out the scale； the reliability was assessed by Cronbach's α； the structural validity was assessed by exploratory and confirmatory factor analysis， and the content validity was assessed by correlation analysis. ResultsThe C-SETS consists of 10 items， with the 1st， 3rd， and 5th rating items constituting the Positive Expectations subscale， and the 2nd， 4th， and 6th rating items constituting the Negative Expectations subscale， each of which is rated on a 7-point Likert Scale. The recall of C-SETS was 100%（96/96）， the completion rate was 89.58%（86/96）； Cronbach's α for the Positive and Negative Treatment Expectations subscales were 0.845 and 0.854， respectively； exploratory factor analysis showed that the coefficient of commonality for all six entries was larger than 0.4， and that the six entries could be used by both factors to explain 77.092% of the total variance； validation factor analysis showed that the goodness-of-fit index， comparative fit index， root mean square of approximation error， canonical fit coefficient， and chi-square degrees of freedom ratio took the values of 0.943， 1.003， 0， 0.943， and 0.626， respectively； and the results of Spearman's analysis suggested that the C-SETS had good content validity. ConclusionThe C-SETS has well feasibility， reliability， and validity， which initially proves that it can be used as a tool to assess the treatment expectation of patients with IBS-D with liver-constraint and spleen-deficiency syndrome before receiving TCM treatment.

Objective: To provide high-quality clinical evidence of the efficacy of Tibetan medicine Honghua Ruyi (HHRY) pills for endometriosis-associated dysmenorrhea. Methods: This study constitutes a multicenter, randomized, double-blind, placebo-controlled trial encompassing a three-menstrual cycle intervention followed by a three-menstrual cycle follow-up period. A total of 164 eligible females with endometriosis-associated dysmenorrhea were randomly divided into HHRY pills and placebo groups in a 1:1 ratio. The primary outcome included dysmenorrhea symptoms assessed using Visual Analog Scale (VAS) scores and quality of life, whereas the secondary outcome measures included the maximum VAS for non-menstrual pelvic pain, duration of pain episodes (in days), frequency and quantity of the consumption of ibuprofen sustained-release capsules (or other non-steroidal anti-inflammatory drugs), and days off work/study for staff/student due to dysmenorrhea, ovarian cyst, and/or pelvic nodule size. The safety was monitored throughout the treatment period. All the analyses were based on the intention-to-treat principle. For continuous outcomes, simple or multiple linear regressions were used to estimate the differences between the HHRY pills and placebo groups, with categorical data expressed as the number and percentage of occurrences. Differences were compared using the chi-square test or Fisher's exact test. The predefined analysis was adjusted for concomitant treatment, a variable considered to be associated with outcomes but unaffected by treatment allocation. Estimates of treatment effects were reported with 95% confidence intervals. Two-tailed P values ≤ .05 were considered statistically significant. Conclusion Positive results from this trial, upon completion would provide robust evidence for the efficacy and safety of HHRY pills in treating dysmenorrhea in patients with endometriosis.

Objective To investigate the therapeutic effects of Isaria felina derived from Cordyceps sinensis combined with cyclophosphamide(CTX)in hepatoma H22 tumor-bearing mice.Methods An H22 tumor-bearing mouse model was established and mice were divided randomly into a normal control group(NC group,distilled water),model control group(MC group,distilled water),positive control group(CTX group,25 mg/kg),Isaria felina group(IF group,400 mg/kg),and combined administration group(IF+CTX group,IF 400 mg/kg+CTX 25 mg/kg),with 5 mice in each group.Distilled water and IF were administered by gavage,and CTX was administered by intraperitoneal injection.The administration cycle was 10 days.At the end of the experiment,the mean tumor volume and weight,tumor inhibition rate,q value,and immune organ index were calculated,and routine blood indexes and cytokine levels were determined.Histopathological changes in tumor tissues were observed by HE staining.Results The tumor volume and mass were significantly lower in mice in each treatment group compared with those in mice in the MC group(P＜0.05).The tumor inhibition rates in the CTX,IF,and IF+CTX groups were 49.3%,34.2%,and 72.8%,respectively,and the q value was 1.09.The numbers of white blood cells,Lymph,and platelets were significantly higher in the IF+CTX group than in the CTX group(P＜0.05).The spleen index was significantly higher in the MC group compared with that in the NC group,and significantly lower in the IF+CTX group compared with that in the MC group(P＜0.05).Serum interferon-γ levels were significantly lower in the MC group than in the NC group,and were significantly higher in the IF and IF+CTX groups compared with those in the MC and CTX groups(P＜0.05).Pathologically,tumor cells in the MC group grew well and were numerous and closely arranged,while cells in the CTX,IF,and IF+CTX groups were arranged loosely,with focal necrosis and nuclear pyknosis of necrotic cells in many places.Conclusions The combination of IF and CTX has an additive anti-tumor effect on H22 tumor-bearing mice,which can alleviate immunosuppression and have an immunomodulatory function.

Objective:To investigate the mechanism of excessive iodine-induced apoptosis of chorionic trophoblast cells associated with missed early miscarriage.Methods:Patients with unexplained missed early miscarriage ≤12 weeks of gestation (MA group, n = 43) and normal pregnant women (control group, n = 64) who were treated at Tianjin Central Obstetrics and Gynecology Hospital from September 2019 to September 2022 were selected as the study subjects, and villous tissues were collected for proliferating cell nuclear agtigen Ki67 immunohistochemistry and apoptosis assay, while urine samples were collected for urinary iodine content assay. Different doses of iodine were used to stimulate the cultivation of human chorionic trophoblast cell line (HTR8/SVneo) for 24 h. Cell proliferation viability was detected using cell counting kit 8 (CCK8), and apoptosis was detected using flow cytometry. Results:(1) Urinary iodine values were 159.70 (114.21, 218.73) μg/L in the control group and 210.80 (143.10, 336.70) μg/L in the MA group, the difference between the two groups was statistically significant ( Z = 2.26, P = 0.024). (2) The proportion of positive and strong positive Ki67 immunohistochemical staining of the villous tissues in the MA group was significantly lower than that in the control group (χ 2 = 37.00, P < 0.001). (3) The apoptosis rate of villous tissue in the MA group was significantly higher than that in the control group [(26.24 ± 1.06)% vs (2.96 ± 1.97)%, t = 92.23, P < 0.001]. (4) The cell proliferation rates of HTR8/SVneo in the 50, 100, 300 and 500 μg iodine groups were significantly lower than that in the 0 μg iodine group ( P < 0.05), with the 500 μg iodine group below the median lethal dose (LD 50). (5) The apoptosis rates of 0, 50 and 500 μg iodine groups were (8.79 ± 0.12)%, (9.56 ± 0.08)% and (19.86 ± 0.05)%, respectively, and the differences among the three groups were statistically significant ( F = 7.32, P = 0.007); in which the 50 and 500 μg iodine groups were higher than that of the 0 μg iodine group, and the 500 μg iodine group was higher than that of the 50 μg iodine group ( P < 0.05). Conclusions:Urine iodine content significantly increases in patients with missed early miscarriage. Excessive iodine intake may lead to a decrease in the proliferation viability and an increase in cell apoptosis of chorionic trophoblast cells.

ObjectiveTo study the efficacy of Aclasta combined with Liuwei Dihuangwan on osteoporosis and the effect on quality of life. MethodA total of 126 patients with osteoporosis who were treated in the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September 2019 to September 2020 were classified into the observation group and the control group with the randomized double-blind method. The observation group consisted of 60 patients （26 males and 34 females） with the age of 59-85 years old ［mean： （72.0 ± 6.5） years old］. The control group was composed of 66 patients （31 males and 35 females）， with the age of 62-82 years old ［mean： （73.0±8.2） years old］. The control group was treated with Aclasta， and the observation group Aclasta combined with Liuwei Dihuangwan. After treatment， the effective rate of each group was calculated. Bone mineral density （BMD） was measured in both groups before and after treatment， and serological parameters calcium （Ca）， total 25 （OH） vitamin D₃ （VITD-T）， osteocalcin （OC）， serum alkaline phosphatase （ALP）， parathyroid hormone （PTH）， β-collagen special sequence （β-CTX）， and total procollagen 1 N-terminal propeptide （T-P1NP） were also measured. Visual Analogue Scale （VAS） score， Japanese Orthopaedic Association （JOA） score， and Oswestry Disability Index （ODI） score were evaluated. On this basis， the effect was compared between the two groups. ResultThe indexes were insignificantly different between the two groups before treatment. After 6 months of treatment， the two groups showed decrease in VAS score and ODI score （P<0.01）， increase in JOA score （P<0.01）， BMD of lumbar spine and hip joint， elevation of Ca， VITD-T， OC， ALP， and PTH （P<0.05， P<0.01）， and decrease of β-CTX （P<0.01） as compared with before treatment. The level of T-P1NP dropped in the observation group after treatment （P<0.01）.After treatment， the total effective rate of the observation group was 88.3% （53/60）， as compared with the 74.2% （49/66） in the control group （χ²=4.047， P<0.05）. Moreover， after treatment， the observation group demonstrated higher levels of BMD， Ca， VITD-T， OC， and PTH （P<0.05）， lower levels of T-P1NP （P<0.05）， lower VAS score （P<0.01）， and higher JOA score （P<0.05） than the control group， but the ODI score was insignificantly different from that in the control group. ConclusionAclasta combined with Liuwei Dihuangwan is effective on osteoporosis， without increasing the incidence of adverse reactions. In addition， the combination can alleviate pain and improve the quality of life of osteoporosis patients.

Lung cancer is currently one of the most common malignant tumors in the world. The occurrence and development of lung cancer, especially non-small cell lung cancer (NSCLC), are closely related to the abnormal expression of long non-coding RNA (lncRNA). lncRNA with a transcript of more than 200 nucleotides is involved in chromatin modification, transcription activation, transcription interference and other regulatory processes, and has varying degrees of regulation on the proliferation, migration, and invasion of tumor cells. It is characterized by up-regulation or down-regulation of expression. At present, there are a large number of studies on lncRNA, because lncRNA has considerable application prospects in the diagnosis, clinical treatment, drug resistance research and prognosis evaluation of NSCLC. In this paper, the overview of lncRNA, the up-regulation or down-regulation of NSCLC-related lncRNA expression, NSCLC clinical treatment and drug-resistant lncRNA were summarized.

Objective:To analyze the characteristics of malaria epidemic situation before and after malaria elimination in Qiandongnan Prefecture, and to provide the basis for establishment of effective strategies and measures to consolidate the achievements of malaria prevention and control.Methods:The data of malaria cases in 16 counties (cities) of Qiandongnan Prefecture from 2005 to 2018 were collected, and descriptive epidemiological method was used to analyze the infection rate of Plasmodium among local residents and floating population before (2005-2011) and after (2012-2018) elimination of malaria, and the characteristics of population distribution, seasonal distribution, species of Plasmodium and types of malaria vectors were analyzed. Results:Before elimination of malaria, total of 1 412 cases of malaria were reported, among those cases, 1 361 cases were local cases, accounting for 96.39% of the total cases. After elimination of malaria, total of 17 cases were reported, all of them were imported cases. After comparison of malaria cases before and after the elimination, the proportion of people aged from 18 to 60 was 70.54% (996/1 412) before the elimination, all 17 imported cases were 18-60 years old after the elimination, and the proportion of children/students decreased from 24.65% (348/1 412) before the elimination to 0 after the elimination. The peak incidence of malaria cases before the elimination was from June to October, and cases occurred every month. After the elimination, the imported cases were sporadic. Plasmodium vivax was the main species of Plasmodium before the elimination (98.58%, 1 392/1 412), and Plasmodium falciparum was mainly imported after the elimination (70.59%, 12/17). Before and after the elimination, Anopheles sinensis, the malaria vector, was the dominant population, but no distribution of Anopheles minimus and Anopheles anthropophagus was found after 2015. Conclusions:After the elimination of malaria in Qiandongnan Prefecture, there is a risk of local malaria cases caused by imported cases. It is suggested that local authorities should focus on the treatment of suspected malaria cases and vector surveillance of overseas returnees in the future.

Neck myoclonus is part of sleep-related dyskinesia characterized by sudden myoclonus during night sleep. Myoclonus causes pronounced brief rotation or flexion of the head. As a single event, neck myoclon ususually occurs during rapid eye movement (REM) sleep, and it lasts longer than 0.5-1.0 s. At present, neck myoclonus is rarely reported. A 28-year-old male whose clinical manifestation was repeated head swing during sleep was admitted to Tangdu Hospital. Video-polysomnography showed that all the events occurred during REM sleep, and some of them were accompanied by micro-arousal reaction and leg movement. Small does of clonazepam could relieve symptoms.
