The role of kaempferol in gynaecological malignancies: progress and perspectives.

Kaempferol, a flavonoid derived from various herbs such as cocoyam, propolis, and grapefruit, has garnered interest due to its numerous pharmacological benefits, including anti-inflammatory, antioxidant, and anti-diabetic properties. Kaempferol has been shown to possess notable anti-tumour bioactivity, indicating potential for treating gynaecological malignancies. To date, numerous studies have demonstrated the potential of kaempferol to induce tumour cell apoptosis, inhibit proliferation, and prevent metastasis and invasion in several gynaecological malignancies, including breast, ovarian and endometrial cancers. However, there is currently insufficient research investigating the efficacy of kaempferol for the treatment of gynaecological malignancies, and a lack of systematic review of its mechanism of action. Therefore, this review is founded on a literature analysis of the anticancer effects of kaempferol on gynaecological malignancies. The goal is to provide valuable reference material for scientific researchers and medical practitioners.

Efficacy and Safety of Acupuncture in the Treatment of Radicular Cervical Spondylosis: A Systematic Review and Meta-Analysis.

BACKGROUND: Cervical spondylotic radiculopathy is a serious and common degenerative disease of the cervical spine due to irritation and compression of the nerve roots of the cervical spine, resulting in a series of clinical symptoms based on sensory, motor and reflex disorders, such as numbness and pain in the neck, shoulders, upper limbs and fingers. Acupuncture is highly effective in treating CSR and has become a common treatment accepted by patients. This study aims to systematically review and analyze existing randomized controlled trials (RCTs) to evaluate the efficacy and safety of acupuncture in the treatment of CSR. METHODS: We used the following eight databases for literature data search: PubMed, EMBASE, The Cochrane Library, Web of Science, China National Knowledge Infrastructure, China Biology Medicine Disc ( CBMdisc), Wanfang Database and China Science and Technology Journal Database (VIP). The search consisted of randomized controlled studies of acupuncture for CSR between 2000 and 2020 and the methodological quality of the included studies was assessed according to the Cochrane Collaboration's "Risk of Bias Assessment Tool."RevMan 5.4 software was used for statistical analysis only. Study screening, data extraction and statistics, and assessment of the risk of bias of the included studies were performed independently by two reviewers. RESULT: 27 studies with 3124 patients were included. The results of the meta-analysis of the total efficiency index for acupuncture for CSR were [RR = 1.14,95% CI (1.09,1.19)]. The results of the meta-analysis of the PPI index were [MD = -0.35, 95% CI (-0.61,-0. 09)]. The results of META analysis of the total effective rate, VAS score, PRI(A) score, PRI(S) score and PRI(T) score showed heterogeneity in the studies included for each outcome index, and sources of heterogeneity were sought through subgroup analysis and sensitivity analysis to ensure more stable and reliable data results. The results of the combined meta-analysis showed that the treatment group was significantly more effective than the control group and more effective in lowering the nerves to reduce the pain index in patients with CSR, with a statistically significant difference (P<0.05). This indicates that acupuncture treatment is superior to traction for CSR. CONCLUSION: Acupuncture is significantly more effective than traction therapy in the treatment of cervical spondylosis and can reduce the pain index of patients with CSR.

Reabsorption of intervertebral disc prolapse after conservative treatment with traditional Chinese medicine: A case report.

BACKGROUND: Conservative treatments have been reported to diminish or resolve clinical symptoms of lumbar intervertebral disc herniation (LIDH) within a few weeks. CASE SUMMARY: Computed tomography and magnetic resonance imaging (MRI) of the lumbar region of a 25-year-old male diagnosed with LIDH showed prolapse of the L5/S2 disc. The disc extended 1.0 cm beyond the vertebral edge and hung along the posterior vertebral edge. The patient elected a conservative treatment regimen that included traditional Chinese medicine (TCM), acupuncture, and massage. During a follow-up period of more than 12 mo, good improvement in pain was reported without complications. MRI of the lumbar region after 12 mo showed obvious reabsorption of the herniation. CONCLUSION: A conservative treatment regimen of TCM, acupuncture, and massage promoted reabsorption of a prolapsed disc.

Efficacy and safety of nonpharmacological strategies for the treatment of oligoasthenospermia: a systematic review and Bayesian network meta-analysis.

BACKGROUND: Oligoasthenospermia (OAT) is the most common cause of male infertility, and the annual incidence of the disease continues to increase due to changing lifestyle habits, increased work pressure and increased environmental pollution. A variety of nonpharmacological therapies have been reported to be effective for treating OAT; however, there is a lack of direct evidence comparing these different nonpharmacological therapies. Therefore, the optimal strategy has yet to be identified. OBJECTIVES: A network meta-analysis was performed to evaluate the efficacy and safety of nonpharmacological treatments for OAT, thus providing an evidence-based medical reference for the clinical treatment of oligoasthenospermia. METHODS: The Web of Science, Cochrane Library, Embase, PubMed, Weipu (VIP), Wan Fang Data, China National Knowledge Infrastructure (CNKI), and China Biomedical Literature (CBM) databases were searched from inception to April 2022 to identify randomized controlled trials (RCTs) that examined nonpharmacological treatments for oligozoospermia. Grey literature was also searched. Studies that met the quality criteria were analysed using Stata 16.0 and Review Manager 5.4 software. RESULTS: A total of 4629 publications were initially retrieved; ultimately, 38 RCTs were analysed, including 8 nonpharmacological therapies and 3080 patients. Each intervention outperformed the sham intervention and no treatment approaches in terms of improved efficacy. In terms of improved total effective rate and sperm concentration, warming acupuncture may be the most effective treatment (SUCRA = 80.1% and 93.4%, respectively). Electroacupuncture perhaps resulted in the best improvement in sperm motility a% and a + b% (SUCRA = 96.6% and 82.0%, respectively). In terms of the incidence of adverse reactions, the three safest interventions probably were no treatment, warming acupuncture, and sham intervention (SUCRA = 88.0%, 68.8% and 62.9%, respectively). In terms of improving the reproductive hormones FSH, LH, and T, the best interventions perhaps were hyperbaric oxygen, 2 Hz TEAS, and electroacupuncture (SUCRA = 85.1%, 96.8% and 99.4%, respectively). CONCLUSIONS: Nonpharmacological treatments for oligoasthenospermia have good clinical efficacy. Warm acupuncture and electroacupuncture have better overall efficacy and safety. These treatment approaches can be recommended based on the actual situation. If a patient is complicated with varicoceles, they should be removed before symptomatic treatment. Due to the limitations of the quality of the included studies, the findings need to be further validated.

Background: Knee osteoarthritis is a common clinical disease with frequent occurrence. More and more studies have shown that external therapies such as acupuncture and massage are beneficial to the treatment of knee osteoarthritis. Objective: The purpose of this systematic review and meta-analysis of randomized controlled trials (RCTS) was to evaluate the efficacy and safety of acupuncture and massage combined with treatment of KOA and to provide some reference for clinical treatment of KOA. Methods: Network meta-analysis was used to evaluate the efficacy of acupuncture combined with massage in the treatment of knee osteoarthritis. PubMed, Cochrane Library, Web of Science, Embase, Chinese Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), VIP, and Wanfang were searched by computer for randomized controlled trials on acupuncture combined with massage in the treatment of knee osteoarthritis. All researchers independently screened the literature, extracted data, and evaluated quality, and studies that met the quality criteria were analyzed using Stata16.0 software. Results: A total of 3076 articles were retrieved, and finally, 49 studies involving 10 acupuncture combined with massage methods were included. The total sample size was 4458, including 2182 in the experimental group and 2276 in the control group. The results of network meta-analysis showed the following: in terms of effective rate, the optimal first three interventions were floating needle+massage, needle knife+massage, and silver needle+massage; in terms of reducing VAS score, the optimal first three interventions were common acupuncture+massage, needle knife+massage, and warm needle+massage; in terms of improving total Lysholm index score, the optimal first three interventions were silver needle+massage, electroacupuncture+massage, and needle knife+massage; in terms of reducing total WOMAC score, the optimal first three interventions were silver needle+massage, electrothermal needle+massage, and common acupuncture+massage; in terms of reducing WOMAC stiffness score, the optimal first three interventions were warm needle+massage, silver needle+massage, and common acupuncture+massage; and in terms of reducing WOMAC joint function score, the optimal first three interventions were silver needle+massage, warm needle+massage, and common acupuncture+massage. Conclusion: The results showed that acupuncture combined with massage could improve the clinical therapeutic effect of patients with knee osteoarthritis. Limited by the quality of the included studies, the conclusions obtained still need to be further validated.

Retraction of lumbar disc herniation achieved by noninvasive techniques: A case report.

BACKGROUND: Lumbar disc herniation (LDH) has emerged as one of the most common causes of low back pain. The routine treatment approach involves chemonucleolysis therapy, discectomy by percutaneous endoscopy, and percutaneous laser disc decompression. Unfortunately, all of these methods carry inherent risk of causing harm to the patient and, as such, there is an unmet but urgent need for an effective and safe noninvasive treatment for LDH. The purpose of this report is to describe a non-invasive method for re-absorption of LDH. CASE SUMMARY: A 34-year-old woman was admitted with a complaint of waist pain that she reported as having become acutely aggravated over the past 3 d and accompanied by discomfort in the right lower limb. Her self-reported medical history included persistent postpartum low back pain from 7 years prior. Physical exam showed positivity for neck flexion test (Lindner sign) and supine abdomen test; the straight leg-raising test showed right 60(+) and left 80(-). Findings from standard imaging (magnetic resonance) and collective physical examinations indicated a L5/S1 herniated lumbar disc. Treatment consisted of three-dimensional (balanced regulating) spinal manipulation and acupuncture, upon which the LDH resolved by retraction. CONCLUSION: Following L5/S1 herniated lumbar disc diagnosis, three-dimensional (balanced regulating) spinal manipulation combined with acupuncture therapy is an effective treatment.

Serum Irisin as a Potential Biomarker for Cognitive Decline in Vascular Dementia.

Background: Irisin, a new exercise-related myokine, has been shown to be associated with a variety of diseases including serious neurological disorders. However, whether irisin is involved in the pathogenesis of vascular dementia (VD) has not yet been reported. Our aim is to determine the serum irisin level in patients with VD and investigate its relationship with cognitive function. Methods: The subjects of the study were VD patients and controls with normal cognitive function who were hospitalized in the Neck-Shoulder and Lumbocrural Pain Hospital of Shandong First Medical University from July 2018 to June 2020. Upon admission, a cognitive function assessment was performed. Enzyme-linked immunosorbent assay (ELISA) was used to determine the concentration of irisin in serum. Results: During the study period, 187 subjects (82 controls and 105 VD patients) were included in the analysis. The serum irisin level of VD patients was significantly lower than that of the control group (p < 0.001). Spearman analysis showed that irisin was positively correlated with HLD-C and MoCA, and negatively correlated with all clinical characteristics except for HCY. Logistic regression analysis showed that after adjusting for all clinical characteristics, the serum irisin of VD patients still had a significant correlation with MoCA (ß = 0.304, p = 0.029). According to receiver operating characteristic (ROC) curve analysis, the diagnostic accuracy for serum irisin levels on VD was 76% with the sensitivity and 71% with specificity respectively. Conclusions: These data indicate that a decrease in serum irisin levels is a powerful biological marker for cognitive decline in patients with VD, even after adjustment for risk factors. Further multi-center studies need to confirm this connection, which may pave the way for new treatment options.

Mechanism of Radix Astragali and Radix Salviae Miltiorrhizae Ameliorates Hypertensive Renal Damage.

Hypertensive-induced renal damage (HRD) is an important public health and socioeconomic problem worldwide. The herb pair Radix Astragali- (RA-) Radix Salviae Miltiorrhizae (RS) is a common prescribed herbal formula for the treatment of HRD. However, the underlying mechanisms are unclear. The purpose of our study is to explore the mechanism of combination of Radix Astragali (RA) and Radix Salviae Miltiorrhizae (RS) ameliorating HRD by regulation of the renal sympathetic nerve. Thirty 24-week-old spontaneously hypertensive rats (SHRs) as the experimental group were randomly divided into the RA group, the RS group, the RA+RS group, the valsartan group, and the SHR group and six age-matched Wistar Kyoto rats (WKY) as the control group. After 4 weeks of corresponding drug administration, venipuncture was done to collect blood and prepare serum for analysis. A color Doppler ultrasound diagnostic instrument was used to observe renal hemodynamics. Enzyme-linked immunosorbent assay was used to detect norepinephrine (NE), epinephrine (E), angiotensin II (Ang II), and B-type brain natriuretic peptide (BNP). Simultaneously, the kidneys were removed immediately and observed under a transmission electron microscope to observe the ultrastructural changes. And the concentration of transforming growth factor-ß1 (TGF-ß1), angiotensin type 1 receptor (AT1), and nitric oxide (NO) was detected by immunohistochemistry. Our results showed that renal ultrasonography of rats showed no significant difference in renal size among groups. The RA+RS group had obviously decreased vascular resistance index. The levels of NE, E, BNP, Ang II, AT1, and TGF-ß1 were decreased (P < 0.05), and the density of NO was increased. Pathological damage of the kidney was alleviated. In conclusion, the results of the present study suggested sympathetic overexpression in the pathogenesis of HRD. The combination of RA and RS may inhibit the hyperexcitability of sympathetic nerves and maintain the normal physiological structure and function of kidney tissue and has a protective effect on the cardiovascular system.

Clinical Efficacy and Safety of "Three-Dimensional Balanced Manipulation" in the Treatment of Cervical Spondylotic Radiculopathy by Finite Element Analysis.

Cervical spondylotic radiculopathy (CSR) is the most commonly encountered cervical spine disorder. Cervical manipulation has been demonstrated as an effective therapy for patients. However, the mechanisms of manipulations have not been elucidated. A total of 120 cervical spondylotic radiculopathy patients were divided into the "three-dimensional balanced manipulation" treatment group (TBM group) and control group randomly. The control group was treated with traditional massage; the TBM treatment group was treated with "three-dimensional balanced manipulation" based on traditional massage. The symptoms and clinical efficacy of the patients were compared before and after treatment for one month. A three-dimensional finite element model was established. The mechanical parameters were imported to simulate TBM, and finite element analysis was performed. The results showed that the total effective rate was significantly higher in the TBM group compared with the control group. The biomechanical analysis showed the vertebral body stress was mainly distributed in the C3/4 spinous processes; the deformation mainly concentrated in the anterior processes of the C3 vertebral body. The intervertebral disc stress in the C3~C7 segment was mainly distributed in the anterior part of the C3/4 intervertebral disc, and the deformation extends to the posterior part of the C3/4 nucleus pulposus. In summary, these data are suggesting that TBM was effective in CSR treatment. The results of the finite element model and biomechanical analysis provide an important foundation for effectively avoiding iatrogenic injuries and improving the effect of TBM in the treatment of CSR patients.

The Separation of Antler Polypeptide and Its Effects on the Proliferation and Osteogenetic Differentiation of Bone Marrow Mesenchymal Stem Cells.

BACKGROUND: Colla Cornus Cervi (CCC) has been used as a traditional Chinese medicine in the treatment of osteoporosis and osteonecrosis of the femoral head. However, the bioavailability of CCC is seriously limited owing to its large molecular weight and complex ingredients. In the present study, antler polypeptide was separated from CCC, and the effects of antler polypeptide on rat bone marrow mesenchymal stem cells (BMSCs) were investigated. METHODS: Antler polypeptide was separated from Colla Cornus Cervi by ultrafiltration into different samples according to the molecular weight. The total peptide content of these samples was determined by the biuret method. The content of antler polypeptide in different samples was quantified by high-performance liquid chromatography (HPLC). The effects of antler polypeptide at different concentrations on the proliferation, cell cycle, alkaline phosphatase activity, and BMP7 expression of BMSCs were investigated. RESULTS: Antler polypeptide was separated by ultrafiltration into different samples: A (molecular weight <800 Da), B (molecular weight 800-1500 Da), and C (molecular weight >1500 Da). The total peptide contents of A, B, and C were 0.602 mg/mL, 8.976 mg/mL, and 38.88 mg/mL. Antler polypeptide B eluted at 14.279∼15.351 min showed that the content of antler polypeptide was significantly higher than that of A and C with a peak area of 933.80927. The BMSCs proliferation rate (84.66%) of polypeptide B was the highest at the concentration of 1.578 × 10-2 g/mL. Antler polypeptide B significantly promoted the proliferation of BMSCs with a proliferation index of 38.68%, which was significantly higher than that of the other groups. Antler polypeptide B significantly enhanced the activity of alkaline phosphatase in BMSCs compared to that of the blank group (P < 0.001). Antler polypeptide B increased the BMP7 protein expression in BMSCs. CONCLUSIONS: Results suggested that antler polypeptide may promote the proliferation and osteogenic differentiation of BMSCs. Our study lays an experimental foundation for the further development and application of antler polypeptide in medicine.

[Finite element analysis of the treatment of cervical spondylotic radiculopathy with three dimensional balanced manipulation].

OBJECTIVE: To explore the biomechanical characteristics of "three-dimensional balanced manipulation" for the treatment of cervical spondylotic radiculopathy(CSR). METHODS: A CSR patient was treated with "three-dimensional balanced manipulation", and the mechanical changes during the manipulation were monitored by mechanical testing system. Using spiral CT to scan the neck of the patient to obtain DICOM data. The three-dimensional finite element model of cervical spondylotic radiculopathy was established by using Mimics software, Geographic Studio software. The "three-dimensional balance manipulation" was simulated and loaded, and the mechanical parameters of each part were replaced into the finite element model, and the finite element analysis was carried out by using ANSYS software to study the internal stress changes and displacement deformation of vertebral body and intervertebral disc under the action of "three-dimensional balance manipulation". RESULTS: The established C3-C7 finite element model of the CSR patient consisted of 5 vertebrae, 4 intervertebral discs and 3 ligaments, involving 153 471 nodes and 64 978 units. The stress of C3-C7 vertebral body was mainly located in anterior and root of C5 spinous processes, arch, vertebral arch and the combination of the two after full loading of manipulation, and the maximum stress was 17.781 MPa. The deformation sites were mainly concentrated in articular processes and anterior transverse processes of C3, superior articular processes and transverse processes of C4, articular processes of C5. The stress of C3-C7 intervertebral disc mainly distributed in the anterior part of C3, 4 intervertebral disc and the nucleus pulposus of C4, 5 and C5, 6. The displace mentextended to the middle and posterior part of C3, 4 nucleus pulposus, around the nucleus of C4, 5 and C5, 6 and anterior part of cervical intervertebral disc. CONCLUSION: The establishment of three-dimensional finite element model of C3-C7 cervical spondylotic radiculopathy can simulate the geometry and material properties of cervical spine, and also accurately reflects the biomechanical characteristics of cervical spine, verifys the internal mechanism of "three-dimensional balanced manipulation" on CSR, proves the safety and effectiveness of treatment, guides more standardized manipulation, and avoids medical accidents.

Tuina for functional constipation: A protocol for the systematic review of randomized clinical trials.

BACKGROUND: Functional constipation (FC) is one of the most common functional gastrointestinal disorders, which brings many negative impacts to the patient's daily life. In the treatment of FC, Tuina (Chinese massage) is often performed as complementary and alternative medicine and shows a good effect in many clinical trials. However, no high-quality systematic review was taken to show the efficacy and safety of Tuina for FC. METHODS: The electronic databases of Cochrane Library, Web of Science (WOS), MEDLINE, Wiley, Springer, EMBASE, Chinese Science Citation Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese Scientific Journal Database, Wan-fang database, and other databases will be searched from the establishment to February 1, 2019. Randomized controlled trials about this theme will be retrieved. Independent reviewers will operate literature retrieval, duplication removing, screening, quality evaluation, data analyses by EndNote (X9) and Review Manager (5.3.5). Meta-analysis, subgroup analysis and/or descriptive analysis will be performed based on the included data form. RESULTS: Evidenced outcome will be provided from defecation frequency, stool consistency (Bistol stool scale), success rates, quality of life, proportion of patients using laxatives, and adverse effects. CONCLUSION: This review will provide evidence of whether Tuina is an effective and safe intervention for FC. TRAIL REGISTRATION NUMBER: This protocol of systematic review has been registered on PROSPERO website (No. CRD42019119722).

Expression of chemokine receptor CXCR4 is closely correlated with clinical outcome in human nasopharyngeal carcinoma.

The CXC chemokine receptor 4 (CXCR4) has been reported to be involved in the development and progression of nasopharyngeal carcinoma (NPC). However, the role of CXCR4 in clinical outcome and prognosis of NPC patients remains controversial. In the present study, we investigated and reviewed the expression of CXCR4 in NPC tissues and then analyzed the definitive role of CXCR4 in clinical outcome and prognosis. Here, we found that the expression level of CXCR4 was significantly higher in NPC cancer specimens (61/98) than that in paired non-tumor tissues (p < 0.001). Together with our pathological analysis, statistic analysis revealed that CXCR4 expression was indeed closely correlated with UICC stage (p = 0.000), N stage (p = 0.019), and metastasis (p = 0.000). Most importantly, the systematic review combined with our survival and multivariate analysis that revealed high expression of CXCR4 was obviously associated with poor overall survival (OS) (p = 0.000) and progression-free survival (PFS) (p = 0.000) and can act as an independent prognostic factor in NPC patients. In conclusion, this study suggests that CXCR4 is highly activated and expressed in the development of NPC and may be recommended as an indicator in the diagnosis of NPC. Thus, targeting of CXCR4 gene or protein could be used as a potential therapy for NPC.
