OBJECTIVES: To explore the therapeutic effect of Fu's subcutaneous needling at myofascial trigger points (MTrPs) on pain, lumbar mobility and the quality of life in patients with lumbar disc herniation (LDH), so as to provide clinicians with new ideas and methods in treating LDH. METHODS: One hundred patients with LDH admitted to department of rehabilitation medicine of the affiliated hospital of Chengdu University of Traditional Chinese Medicine from January 2022 to January 2023 were collected as the subjects, and they were randomly divided into an observation group and a control group, 50 cases in each one. In the observation group, the spreading technique of Fu's subcutaneous needling was delivered at MTrP. In the control group, the routine acupuncture was applied to Shenshu (BL23), Weizhong (BL40) and MTrP. The treatment was given 3 times weekly, for 2 weeks in the two groups. The score of visual analogue scale (VAS) was evaluated before treatment, at the moment after the 1st treatment completion and after 2 weeks of treatment, separately, and the inclinometer was adopted to measure the range of motion (ROM) of the lumbar flexion, extension and lateral flexion. The numbers of MTrPs and their distribution were recorded before treatment and after the completion of a 2-week treatment in the two groups. Before treatment and in 4 weeks of follow-up, using SF-36 scale, the score of the quality of life was evaluated. The incidence of adverse effects was recorded. RESULTS: At the moment of the 1st treatment completion and after 2 weeks of treatment, VAS score and ROM of the lumbar region were significantly improved in comparison with those before treatment in the two groups and the improvement was superior in the observation group compared with the control group (P<0.05, P<0.01). After 2 weeks of treatment, the total number of MTrPs and the counts of MTrPs in each muscle zone were reduced when compared with those before treatment (P<0.05). In the observation group, the total number of MTrPs and numbers of MTrPs in the zones of quadratus lumborum, musculi multifidus and musculi iliocostalis lumborum decreased significantly when compared with the control group (P<0.05), while the difference was not significant in the numbers in the zone of musculi glutaeus medius between the two groups. In 4 weeks of follow-up, the scores of SF-36 scale were improved in comparison with those before treatment in each group and the result in the observation was better (P<0.05). No any adverse events occurred during treatment in the two groups. CONCLUSIONS: Fu's subcutaneous needling is effective for reducing the numbers of MTrPs and improving analgesia, ROM of the lumbar region, as well as the long-term quality of life in the patients with LDH.

Core training for pain management and functional improvement in patients with patellofemoral pain syndrome: a systematic review and meta-analysis.

OBJECTIVE: To investigate the effects of core strengthening exercises on pain, mobility, and lower extremity muscle strength in patients with Patellofemoral Pain Syndrome (PFP). DESIGN: Six databases were searched from inception until August 11, 2023. Pain, function and muscle strength related outcomes were extracted and the quality of the studies was assessed using the PEDro scale and the level of evidence was assessed using the GRADE. RESULTS: Nineteen studies involving 1138 patients were included. Very low-grade evidence supported the short-term pain-relieving effect of core training (SMD = -0.60 95% CI [-0.95, -0.25]), high-grade evidence supported the short-term functional improvement effects of core training (WMD = 3.61 95% CI [1.44, 5.78]), which was similarly significant within 3-12 months of follow-up. The results of the subgroup analyses suggested that hip-knee training was most advantageous in relieving pain and enhancing motor function. CONCLUSIONS: Although training that includes trunk core is clearly superior to knee strengthening alone, the effectiveness of hip-knee training, which is also a core training program for pain and function, is more pronounced. The available evidence supports that hip-knee training is the most valuable treatment option for patients with PFP.

Efficacy of acupuncture combined with active exercise training in improving pain and function of knee osteoarthritis individuals: a systematic review and meta-analysis.

OBJECTIVE: To conduct a systematic review and meta-analysis to investigate the clinical efficacy of acupuncture combined with active exercise training in improving pain and function of knee osteoarthritis (KOA) individuals. DATA SOURCES: PubMed, EMBASE, The Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wan Fang Data, Technology Periodical Database and China Biology Medicine were searched from their inceptions to April 5, 2023. REVIEW METHODS: We analyzed trials of acupuncture combined with active exercise training for KOA. The included studies were of high quality (Jadad ≥ 4) and RCTs. Study selection, data extraction, risk of bias and quality assessment were independently performed by two reviewers. We performed systematic analyses based on different outcome measures, including total efficiency rate, visual analogue scale (VAS), the Western Ontario and Mcmaster Universities Osteoarthritis Index (WOMAC), the Lysholm Knee Scale (LKS) and range of motion (ROM). We used Review Manager 5.3 and Stata/MP 14.0 to analyze the data. And it was verified by trial sequence analysis (TSA). If I2 > 50% and p < 0.05, we performed sensitivity analysis and subgroup analysis to find the source of heterogeneity. Publication bias was studied by funnel plot and Egger's test was used to verify it. RESULTS: Full 11 high-quality studies (Jadad ≥ 4) including 774 KOA individuals were included in this review for meta-analysis. The results showed that acupuncture combined with active exercise training (combined group) was superior to the acupuncture group in improving the total effective rate [RR = 1.13, 95%CI (1.05, 1.22), I2 = 0%, P = 0.70], reducing the pain level (VAS) [MD = - 0.74, 95%CI (- 1.04, - 0.43), I2 = 68%, P < 0.05], improving knee joint function (WOMAC) [MD = - 6.97, 95%CI (- 10.74, - 3.19), I2 = 76%, P < 0.05] and improving joint range of motion (ROM) [MD = 6.25, 95%CI (2.37, 10.04), I2 = 0%, P = 0.71]. Similarly, the combined group showed significant improvements in the total effective rate [RR = 1.31, 95% CI (1.18, 1.47), I2 = 48%, P = 0.10], pain (VAS) [MD = 1.42, 95% CI (- 1.85, - 1.00), I2 = 65%, P = 0.02] and knee function (WOMAC) [MD = 7.05, 95% CI (- 11.43, - 2.66), I2 = 86%, P < 0.05] compared with the non-acupuncture group. CONCLUSION: The combined effect of all studies showed significant benefits of acupuncture combined with active exercise training in improving the total effective rate, reducing pain, promoting recovery of knee function and expanding range of motion. However, some evaluation indicators are highly subjective and need to be further confirmed by more objective and evidence-based high-quality RCTs in future.

Effects of low-frequency rTMS combined with antidepressants on depression in patients with post-stroke depression: a systematic review and meta-analysis.

Objective: To evaluate the effect of low-frequency (≤1 Hz) repetitive transcranial magnetic stimulation (low-frequency rTMS) combined with antidepressants on depression and the levels of inflammatory factors IL-6 and TNF-α in patients with post-stroke depression (PSD). Design: PubMed, Embase, Web of Science, Cochrane Library (CBM), China National Knowledge Infrastructure, Technology Periodical Database, and Wanfang Database were searched until October 2022 for randomized controlled trials. Participants: Patients with post-stroke depression (PSD) participated in the study. Results: A total of 16 randomized controlled trials (RCTs) involving 1,463 patients with PSD were included. According to the Physiotherapy Evidence Database (PEDro) quality assessment, three studies received high quality (eight scores) and 13 RCTs received moderate quality (six scores) results. The meta-analysis showed that low-rTMS combined with an antidepressant significantly reduced the Hamilton Depression Scale (HAMD) score and the National Institutes of Health Stroke Scale (NIHSS) score, reduced IL-6 and TNF-α levels, and improved the MMSE score in PSD compared to an antidepressant alone. Conclusion: The results of this meta-analysis evidenced the efficacy and safety of low-rTMS combined with antidepressants in the treatment of depression in PSD patients. The combined therapy could reduce The depression state and the levels of IL-6 and TNF-α, and enhance the cognitive function of patients. In addition, low-rTMS had fewer adverse effects, proving safety. However, there are shortcomings, such as a lack of long-term follow-up, different intervention sites of low-rTMS, and different intervention frequencies (0.5 or 1 Hz). Thus, in the future, RCTs with a larger sample size and longer-term observation are required to verify the efectiveness of low-rTMS combined therapy on PSD. Meantime, a new meta-analysis could be analysized, which intervention sites and frequency are more effective in treating PSD.

The central-peripheral coupling effect of ocular acupuncture kinesitherapy in post-stroke dyskinesia: A functional neuroimaging and neurotic electrophysiology study protocol.

Background: Dyskinesia is a common manifestation after stroke. Motor functional rehabilitation after stroke is of great significance to the maintenance of national health. Ocular Acupuncture Kinesitherapy (OAKT) can repair nerve injuries, improve motor function, reduce rehabilitation time, and promote dyskinesia recovery after stroke. The mechanism, however, remains a mystery, necessitating urgent research. The M1-thalamus-spinal cord neural signaling pathway is linked to limb motor function. Bold-fMRI can represent the cerebral functional state, and TMS-MEP is of certain practical utility for assessing motor neural function and prognosis. Combining fMRI scanning with TMS-MEP detection is predicted to advance brain-spinal cord regulation and muscle response linkage control mechanism research, as well as completely investigate the central-peripheral coupling effect of Ocular Acupuncture Kinesitherapy on dyskinesia after stroke (PSD). Methods: This is a prospective functional neuroimaging and neurotic electrophysiological study with a case-control design between the PSD with the HC groups and a randomized controlled design within the 3 PSD groups (OAKT group, ocular acupuncture group, and kinesitherapy group). Using fMRI scans and TMS-MEP approach, we will assess the central-peripheral neural function alterations in PSD as well as the coupling effects of OAKT on PSD. We plan to enroll 90 participants at the Hospital of Chengdu University of Traditional Chinese Medicine from Aug 31, 2022, to Dec 31, 2023, including 45 PSD and 45 HC subjects. After enrollment and on the last day after 4-weeks of waiting (HC subjects) or intervention (PSD subjects), all eligible subjects will be evaluated using fMRI scanning, TMS-MEP detection, and the MMT and Fugl-Mayer scales assessment. The MMT and Fugl-Meyer scores will be recorded, and a Pearson correlation analysis will be performed to assess the correlation between clinical and imaging outcomes. Discussion: Findings of this study will help to explain the central-peripheral coupling effect of OAKT on PSD and to further provide the neural processing of acupuncture kinesitherapy covering the entire pathway from peripheral to central nervous system. Clinical trial registration: This study is registered with an identifier (ChiCTR2200060483) at the Chinese Clinical Trial Registry in June 2022. http://www.chictr.org.cn/index.aspx.

A new subset of small stem cells in bovine bone marrow stromal cell populations.

Bone marrow stromal cells (BMSCs) are a unique population of multipotent cells that exhibit pluripotent properties to a certain extent and are significantly heterogeneous in terms of the cell population. We isolate a small cell subpopulation from bovine BMSCs, bovine small stem cells (bSSCs), and herein characterize their properties. The bSSCs are smaller in size and express nuclear Oct-4 and other pluripotency markers. In addition, when cultured in suspension conditions, bSSCs form three-dimensional spheres and display a strong capability for self-renewal and differentiation into cells from three germ layers. Notably, bSSCs display neural features with Sox1 and Pax6 expression. Using bSSCs as donor nuclear cells for somatic cell nuclear transfer, we further demonstrate that the developmental potential of cloned embryos in vitro is significantly increased. Our study identifies a new bovine bone marrow stromal cell-derived stem cell subtype that could have broad importance for developmental biology as well as great potential for regenerative medicine.

Effect of CPAP therapy on cardiovascular events and mortality in patients with obstructive sleep apnea: a meta-analysis.

PURPOSE: Continuous positive airway pressure (CPAP) therapy may decrease the risk of mortality and cardiovascular events in patients with obstructive sleep apnea. However, these benefits are not completely clear. METHODS: We undertook a meta-analysis of randomized clinical trials identified in systematic searches of MEDLINE, EMBASE, and the Cochrane Database. RESULTS: Eighteen studies (4146 patients) were included. Overall, CPAP therapy did not significantly decrease the risk of cardiovascular events compared with the control group (odds ratio (OR), 0.84; 95 % confidence intervals (CI), 0.62-1.13; p = 0.25; I (2) = 0 %). CPAP was associated with a nonsignificant trend of lower rate of death and stroke (for death: OR, 0.85; 95 % CI, 0.35-2.06; p = 0.72; I (2) = 0.0 %; for stroke: OR, 0.56; 95 % CI, 0.18-1.73; p = 0.32; I (2) = 12.0 %), a significantly lower Epworth sleepiness score (ESS) (mean difference (MD), -1.78; 95 % CI, -2.31 to -1.24; p < 0.00001; I (2) = 76 %), and a significantly lower 24 h systolic and diastolic blood pressure (BP) (for 24 h systolic BP: MD, -2.03 mmHg; 95 % CI, -3.64 to -0.42; p = 0.01; I (2) = 0 %; for diastolic BP: MD, -1.79 mmHg; 95 % CI, -2.89 to -0.68; p = 0.001; I (2) = 0 %). Daytime systolic BP and body mass index were comparable between the CPAP and control groups. Subgroup analysis did not show any significant difference between short- and mediate-to-long-term follow-up groups with regard to cardiovascular events, death, and stroke. CONCLUSIONS: CPAP therapy was associated with a trend of decreased risk of cardiovascular events. Furthermore, ESS and BP were significantly lower in the CPAP group. Larger randomized studies are needed to confirm these findings.

Analysis of driver mutations in female non-smoker Asian patients with pulmonary adenocarcinoma.

Previous studies have revealed that EGFR mutation and/or EML4-ALK gene fusion rate was higher in the non-smoker Asian females with pulmonary adenocarcinoma. The aim of this study is to determine the distribution of known oncogenic driver mutations in the female non-smoker Asian patients with pulmonary adenocarcinoma. 104 consecutively resected lung adenocarcinomas from 396 non-smoker females (less than 100 cigarettes in a lifetime) at a single institution (Tongji University, Shanghai, China) were analyzed for mutations in EGFR, EML4-ALK, KRAS, HER2, BRAF, and PIK3CA. 73 (70.2 %) tumors harbored EGFR mutations; among these, 28 were deletions in exon 19, 44 were L858R missense changes, and eight were T790M mutations. 10 (9.6 %) harbored EML4-ALK fusions, two harbored KRAS mutations, two harbored BRAF mutations, and two harbored PI3K mutations. A majority of the mutations were mutually exclusive, except two with EGFR mutation and BRAF mutation, one with EML4-ALK fusions and PI3K mutation. Thus, 82.7 % (86 of 104; 95 % CI, 75.4-90.0 %) of lung adenocarcinomas from non-smoker females were found to harbor the well-known oncogenic mutations in five genes. Lung cancer in non-smoking Asian females is a distinct entity, with majority of this subgroup being developed by the oncogenic mutations. The prospective mutation examination in this population will be helpful for devising a targeted therapy for a majority of the patients.

Association of EGFR mutation or ALK rearrangement with expression of DNA repair and synthesis genes in never-smoker women with pulmonary adenocarcinoma.

BACKGROUND: Epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) rearrangement may predict the outcome of targeted drug therapy and also are associated with the efficacy of chemotherapy in patients with nonsmall cell lung cancer (NSCLC). The authors of this report investigated the relation of EGFR mutation or ALK rearrangement status and the expression of DNA repair or synthesis genes, including excision repair cross-complementing 1 (ERCC1), ribonucleotide reductase subunit M1 (RRM1), thymidylate synthetase (TS), and breast cancer-early onset (BRCA1), as a potential explanation for these observations. METHODS: In total, 104 resected lung adenocarcinomas from women who were nonsmokers were analyzed concurrently for EGFR mutations, ALK rearrangements, and mRNA expression of the ERCC1, RRM1, TS, and BRCA1 genes. EGFR mutations were detected with a proprietary detection kit, ALK rearrangements were detected by polymerase chain reaction analysis, and genetic mRNA expression was detected by real-time polymerase chain reaction analysis. RESULTS: Of 104 patients, 73 (70.2%) had EGFR mutations, and 10 (9.6%) had ALK rearrangements. ERCC1 mRNA levels in patients who had EGFR mutations were 3.44 ± 1.94 × 10(-3) , which were significantly lower than the levels in patients who were positive for ALK rearrangements and in patients who were negative for both biomarkers (4.60 ± 1.95 × 10(-3) and 4.95 ± 2.33 × 10(-3) , respectively; P = .010). However, TS mRNA levels were significantly lower in patients who had EGFR mutations (1.15 ± 1.38 × 10(-3) vs 2.69 ± 3.97 × 10(-3) ; P = .006) or ALK rearrangements (1.21 ± 0.78 × 10(-3) vs 2.69 ± 3.97 × 10(-3) ; P = .020) than in patients who were negative for both biomarkers. CONCLUSIONS: NSCLC specimens that harbored activating EGFR mutations were more likely to express low ERCC1 and TS mRNA levels, whereas patients with NSCLC who had ALK rearrangement were more likely to express low TS mRNA levels.

Preparation of mannan modified anionic PCL-PEG-PCL nanoparticles at one-step for bFGF antigen delivery to improve humoral immunity.

In this article, blank anionic poly(epsilon-caprolactone)-poly(ethylene glycol)-poly(epsilon-caprolactone) (PCEC) and anionic mannan modified PCEC (MPCEC) nanoparticles with nearly the same particle size and zeta potential were prepared by emulsion solvent evaporation method. Human basic fibroblast growth factor (bFGF) was absorbed onto anionic nanoparticles surface due to electrostatic interaction. The obtained bFGF-nanoparticles complexes were injected subcutaneously into C57BL/6 mice at 20 microg of bFGF/dose on week 0, 1, 2 and 3. The mice serum was collected on week 4, and bFGF-specific autoantibody total IgG, IgG1 and IgG2a titer in serum was determined by ELISA. The results indicated that the autoantibody IgG, IgG1 and IgG2a titer of the mice immunized by bFGF-MPCEC complexes were higher than that immunized by either bFGF-PCEC or bFGF-Alum. This phenomenon might be due to that mannan functionalized MPCEC nanoparticles could be targeted to dendritic cells (DCs) to improve humoral immunity. The prepared anionic mannan modified PCEC nanoparticles (MPCEC) might have great potential application in vaccine delivery systems.
