Experimental evidence for anti-metastatic actions of apigenin: a mini review.

Cancer metastasis is responsible for the majority of cancer-related deaths. Accordingly, to reduce metastasis remains a vital challenge in clinical practice, and phytochemicals have taken an attention as anti-metastatic agents. Apigenin, a plant flavone, showed anti-cancer effects against in various animal models, moreover its potentials inhibiting tumor metastasis have been reported. Herein, we analyzed the overall features at what apigenin inhibited metastasis and its action modes. We searched for articles in MEDLINE (Pubmed), EMBASE and Cochrane Central Register of Controlled Trials (CENTRAL) through March 2023. Total 6 animal studies presented anti-metastatic effects of apigenin using 5 difference experimental models, while the mechanisms involved modulations of epithelial-mesenchymal transition (EMT), matrix metalloproteinases (MMPs), angiogenesis, and various metastasis-related signaling pathways. This review provides an overall potential of apigenin as a candidate reducing the risk of cancer metastasis.

Efficacy of Moxibustion for Cancer-Related Fatigue in Patients with Breast Cancer: A Systematic Review and Meta-Analysis.

INTRODUCTION: Breast cancer is the most commonly diagnosed cancer worldwide, and most patients experience fatigue. However, there are no effective treatments for cancer-related fatigue (CRF). Several randomized controlled trials (RCTs) have suggested that moxibustion improves CRF. We conducted a systematic review and meta-analysis to compare the differences in fatigue scale scores, quality of life, and clinical efficacy in patients with breast cancer who developed CRF and did versus did not receive moxibustion. METHODS: RCTs were searched in 7 databases using a standardized search method from database inception to March 2023, and RCTs that met the inclusion criteria were selected. RESULTS: Among 1337 initially identified RCTs, 10 RCTs involving 744 participants were selected for this study. The meta-analysis involved assessment of the revised Piper Fatigue Scale scores, Cancer Fatigue Scale scores, Karnofsky Performance Scale scores, Athens Insomnia Scale scores, clinical efficacy, and Qi deficiency syndrome scale scores. Compared with the control, moxibustion was associated with significantly better Piper Fatigue Scale scores (P < 0.0001), quality of life [Karnofsky Performance Scale scores (P < 0.0001)], clinical efficacy (P = 0.0007), and Qi deficiency syndrome scale scores (P = 0.02). CONCLUSIONS: Moxibustion improves CRF in patients with breast cancer. The efficacy of moxibustion should be further examined by high-quality studies in various countries with patients subdivided by their breast cancer treatment status.

The Clinical Diagnosis-Based Nationwide Epidemiology of Metabolic Dysfunction-Associated Liver Disease in Korea.

BACKGROUND: Although most epidemiological studies have been conducted using a relatively small population or subjects who had medical screenings, the present study aimed to investigate the incidence and prevalence of MASLD (formerly NAFLD) in Korea using nationwide registry data provided by the Health Insurance Review and Assessment Service (HIRA). METHODS: Using nationwide medical records provided by HIRA, we analyzed the entire dataset of patients with MASL (KCD10-K76.0) and MASH (KCD10-K75.8) from 2010 to 2021 and calculated the incidence and prevalence by year, age, and gender. The prevalence and incidence rates were calculated by analyzing the HIRA data covering almost the entire population of Korea for 12 years, from 2010 to 2021, with an average population of 50,856,244 during this period. Statistical analyses included calculating confidence intervals using Ulm's formula and conducting sex- and age-specific analyses with a Cochran-Armitage test for trends. RESULTS: The annual incidence of MASL/MASH increased significantly from 9.71/0.37 in 2010 to 13.95/5.52 per 1000 persons in 2021 (p < 0.01). The annual prevalence of MASL increased from 15.69 in 2010 to 34.23 per 1000 persons in 2021, while the annual prevalence of MASH increased from 0.49 to 9.79 per 1000 persons between 2010 and 2021 (p < 0.01). Regarding the sex-dimorphic feature of MASLD, there was a male predominance in those < 50 years old but a female predominance in those ≥ 50 years old for the incidence and prevalence of MASL and the incidence of MASH. CONCLUSION: The incidence of MASL increased by 3% to 4% every year, while the incidence of MASH increased 14.91-fold from 2010 to 2021. The increasing trend is noteworthy compared with previous reports.

Feasibility of combination of Gun-Chil-Jung and cytokine-induced killer cells-based immunotherapy for terminal hepatocellular carcinoma patient: a case report.

Introduction: Terminal-stage hepatocellular carcinoma (HCC) is inoperable and currently has no form of adjuvant therapy. This study examined the anticancer herbal extract Gun-Chil-Jung (GCJ) combined with cytokine-induced killer (CIK)-cell-based immunotherapy as a palliative therapy for terminal HCC. We report the case of an HCC patient with extended overall survival and improved symptoms and tumor marker levels following combination therapy with GCJ and CIK cell-based immunotherapy. Baseline Characteristics: From March to July 2020, a 57-year-old man who had been diagnosed with HCC underwent combination treatment with GCJ and CIK cell-based immunotherapy. By August 2021, he was prescribed GCJ. After treatment, the patient's condition was evaluated with respect to overall survival, tumor markers, symptoms, abdominal computed tomography findings, chest x-ray results, and Eastern Cooperative Oncology Group (ECOG) grade. Results: The patient's overall survival, tumor marker levels, ECOG grade, and symptoms, including ascites, lower limb edema, jaundice, pleural effusion, and fatigue, were largely alleviated. Conclusion: We expect that this combination therapy may be an option for palliative therapy of terminal HCC.

A Review of Herbal Resources Inducing Anti-Liver Metastasis Effects in Gastrointestinal Tumors via Modulation of Tumor Microenvironments in Animal Models.

Liver metastases remain a major obstacle for the management of all types of tumors arising from digestive organs, and the tumor microenvironment has been regarded as an important factor in metastasis. To discover herbal candidates inhibiting the liver metastasis of tumors originating from the digestive system via the modulation of the tumor microenvironment and liver environment, we searched three representative public databases and conducted a systematic review. A total of 21 studies that employed experimental models for pancreatic (9), colon (8), and stomach cancers (4) were selected. The herbal agents included single-herb extracts (5), single compounds (12), and multiherbal decoctions (4). Curcuma longa Linn was most frequently studied for its anti-colon-liver metastatic effects, and its possible mechanisms involved the modulation of tumor microenvironment components such as vascular endothelial cells and immunity in both tumor tissues and circulating cells. The list of herbal agents and their mechanisms produced in this study is helpful for the development of anti-liver metastasis drugs in the future.

Trend Shift in the Cause of Revision Total Knee Arthroplasty over 17 Years.

Background: The number of revision total knee arthroplasty (TKA) has been increasing. Although many studies have analyzed the causes of revision TKA in Western countries, a limited number of studies have analyzed changes in causes of or trends in revision TKA in Asia. This study analyzed and determined the frequency and causes of failures after TKA in our hospital. We also analyzed the differences and trends over the past 17 years. Methods: A total of 296 revision TKAs performed in a single institution from 2003 to 2019 were analyzed. During the 17-year study period, patients who had undergone primary TKA between 2003 and 2011 were classified into a past group, while those who had undergone primary TKA from 2012 to 2019 were classified into a recent group. A revision performed within 2 years after primary TKA was defined as early revision. Further, differences in causes of revision TKA according to the interval from primary TKA to revision TKA were determined. The causes of revision TKA were analyzed through a comprehensive analysis of patients' medical records. Results: Overall, infection was the most common cause of failure (151/296 cases, 51.0%). Compared to the past group, the recent group had a relatively higher proportion of patients undergoing revision TKA for mechanical loosening (past group, 19.1% vs. recent group, 31.9%) and instability (11.2% vs. 13.5%) and a relatively lower proportion of patients undergoing revision TKA for infection (56.2% vs. 48.8%), polyethylene (PE) wear (9.0% vs. 2.9%), osteolysis (2.2% vs. 1.9%), and malalignment (2.2% vs. 1.0%). On comparison according to the interval from primary TKA to revision TKA, the rate of infection relatively decreased, whereas the rate of mechanical loosening and instability relatively increased in the late revision TKA compared to the early revision TKA. Conclusions: Infection and aseptic loosening were the most common reasons of revision TKA in both past and recent groups. Compared to the past, revision TKA due to PE wear has decreased significantly and revision TKA due to mechanical loosening has relatively increased recently. Orthopedic surgeons need to be aware of recent trends in mechanisms of failure and should try to recognize and address the probable causes in TKA.

Adjuvant effect of herbal medicine on transarterial chemoembolization in patients with hepatocellular carcinoma: A systematic review and meta-analysis.

Objectives: Primary hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths, especially in Asian countries. As a practical treatment option, transarterial chemoembolization (TACE) has been well applied; however, its limited efficacy remains challenging. This study analyzed the adjuvant effects of herbal medicine on TACE to determine whether it improves clinical outcomes in patients with HCC. Methods: A systematic review and meta-analysis was performed to compare the adjuvant effects of herbal medicine on TACE versus TACE therapy alone. We searched the literature from eight databases since January 2011. Results: Twenty-five studies involving 2,623 participants were selected. The adjuvant therapy of herbal medicine on TACE improved the overall survival at 0.5 years (OR = 1.70; 95% CI 1.21-2.38), 1 year (OR = 2.01; 95% CI 1.65-2.46), 2 years (OR = 1.83; 95% CI 1.20-2.80), and 3 years (OR = 1.90; 95% CI 1.25-2.91). The combination therapy also increased the tumor response rate (OR = 1.84; 95% CI 1.40-2.42). Conclusions: Despite the unsatisfactory quality of the included studies, the adjuvant therapy of herbal medicine on TACE may provide survival benefits to patients with HCC.

Coptidis Rhizoma Suppresses Metastatic Behavior by Inhibiting TGF-ß-Mediated Epithelial-Mesenchymal Transition in 5-FU-Resistant HCT116 Cells.

Colorectal cancer (CRC) is the second most lethal malignancy worldwide. The high mortality rate of CRC is largely due to cancer metastasis. Recently, suppressing epithelial-to-mesenchymal transition (EMT) has been considered a promising strategy for treating metastatic cancer, especially drug-resistant metastatic cancer. The present study aimed to evaluate the antimetastatic effect of Coptidis Rhizoma, as well as the potential underlying mechanisms, using a 5-fluorouracil-resistant colon tumor cell model (HCT116/R). Coptidis Rhizoma 30% ethanol extract (CRE) significantly inhibited HCT116/R cells migration and invasion. CRE effectively inhibited EMT in HCT116/R cells by upregulating the expression of an epithelial marker (E-cadherin) and downregulating the expression of mesenchymal markers (vimentin, Snail, and ZEB2) at both the protein and gene levels. Immunofluorescence assays also confirmed consistent patterns in the levels of E-cadherin and vimentin. In addition, the anti-EMT activity of CRE and its related effects were associated with the CRE-mediated suppression of the TGF-ß pathway, as shown by changes in the levels of downstream molecules (phosphorylated Akt and p38), and inhibition of migration, invasion, and protein expression of TGF-ß after treatment/cotreatment with a TGF-ß inhibitor (SB431542). In conclusion, Coptidis Rhizoma exerts an antimetastatic effect, especially in the treatment of drug-resistant cancer, and the possible mechanisms are associated with inhibiting EMT via TGF-ß signaling. Thus, Coptidis Rhizoma will likely become a potential therapeutic candidate for simultaneously mitigating drug resistance and metastasis in CRC.

How Should Patients with a Thoracolumbar Injury Classification and Severity Score of 4 Be Treated?

The thoracolumbar injury classification and severity score (TLICS) system help surgeons decide whether patients should undergo initial operative treatment or nonoperative treatment. However, the best treatment for patients with TLICS 4 fracture remains unknown. The aim of this study was to identify the risk factors for nonoperative treatment failure in patients with TLICS 4 fracture and establish treatment standards for TLICS 4 fractures. This study included 44 patients with TLICS 4 fracture who initially received nonoperative treatment. We divided these patients into two groups: the successful nonoperative treatment group included 18 patients, and the operative treatment group after nonoperative treatment failure included 26 patients. In multiple logistic regression analysis, spinal canal compromise (odd ratio = 1.316) and kyphotic angle (odd ratio = 1.416) were associated with nonoperative treatment failure in patients with TLICS 4 fracture. Other factors, including age, sex, BMI, initial VAS score, and loss of vertebral body height, were not significantly associated with nonoperative treatment failure in these patients. Spinal canal compromise and kyphotic angle were associated with nonoperative treatment failure in patients with TLICS 4 fracture. Therefore, we recommend the surgeon observe spinal canal compromise and kyphotic angle more carefully when deciding on the treatment of patients with TLICS 4 fracture.

Does meniscectomy have any advantage over conservative treatment in middle-aged patients with degenerative medial meniscus posterior root tear?

BACKGROUND: The best treatment for degenerative medial meniscus posterior root tear (MMPRT) remains controversial. This study aimed to compare the clinical and radiological outcomes of arthroscopic meniscectomy and conservative treatment for degenerative MMPRT. METHODS: From January 2007 to December 2014, 146 patients (Meniscectomy group, 90; Conservative group, 56) were evaluated. Clinical outcomes were assessed using the Visual Analog Scale, International Knee Documentation Committee subjective scoring scale, Tegner activity scale, and Lysholm knee scoring scale at the final follow-up. Radiologic outcomes evaluated the progression of osteoarthritis (OA) according to the Kellgren-Lawrence (K-L) classification. We compared the hip-knee-ankle angle (HKAA), medial proximal tibial angle, tibial posterior slope angle, and width of medial joint space. After an average follow-up of 6.3 years, the survivorship was analyzed using the Kaplan-Meier method. RESULTS: All clinical outcomes were significantly improved in both groups after treatment, with no significant differences between the two groups at the final follow-up. The progression of OA according to the K-L classification, HKAA and width of medial joint space was significantly advanced in the meniscectomy group (p = 0.03, 0.04, 0.03, respectively). The 10-year survival rates in the meniscectomy and conservative groups were 87 and 88%, respectively. CONCLUSIONS: This study demonstrated that both conservative treatment and meniscectomy provided symptomatic relief. However, it was confirmed that OA progression was more severe in the meniscectomy. We conclude that arthroscopic meniscectomy had no advantage over conservative treatment in terms of clinical outcomes and OA progression in middle-aged patients with MMPRT. LEVEL OF EVIDENCE: Level III; retrospective comparative study.

Coptidis Rhizoma Extract Reverses 5-Fluorouracil Resistance in HCT116 Human Colorectal Cancer Cells via Modulation of Thymidylate Synthase.

Colorectal cancer (CRC) is a malignancy of the colon or rectum. It is ranked as the third most common cancer in both men and women worldwide. Early resection permitted by early detection is the best treatment, and chemotherapy is another main treatment, particularly for patients with advanced CRC. A well-known thymidylate synthase (TS) inhibitor, 5-fluorouracil (5-FU), is frequently prescribed to CRC patients; however, drug resistance is a critical limitation of its clinical application. Based on the hypothesis that Coptidis Rhizoma extract (CRE) can abolish this 5-FU resistance, we explored the efficacy and underlying mechanisms of CRE in 5-FU-resistant (HCT116/R) and parental HCT116 (HCT116/WT) cells. Compared to treatment with 5-FU alone, combination treatment with CRE and 5-FU drastically reduced the viability of HCT116/R cells. The cell cycle distribution assay showed significant induction of the G0/G1 phase arrest by co-treatment with CRE and 5-FU. In addition, the combination of CRE and 5-FU notably suppressed the activity of TS, which was overexpressed in HCT116/R cells, as compared to HCT116/WT cells. Our findings support the potential of CRE as an adjuvant agent against 5-FU-resistant colorectal cancers and indicate that the underlying mechanisms might involve inhibition of TS expression.

Risk levels of herb-induced liver injury in Korea: from a meta-analysis.

BACKGROUND: As the use of herbal medicines increased worldwide, there has been concern about the risk of herb-induced liver injury (HILI). Many clinical studies have assessed the risk of HILI in Korea. METHODS: Therefore, we conducted a meta-analysis of the incidence of HILI in Korea, by analyzing nine clinical studies. These involved 8625 participants (3274 males; 5351 females), including 436 outpatients (three studies) and 8189 inpatients (six studies). RESULTS: As a result, the overall incidence of HILI in Korea was 0.49% (95% CI 0.33-0.74%), and it was 0.57% in males and 0.30% in females. We found a similar incidence of HILI in prospective (0.51%) and retrospective (0.50%) studies. The incidence of HILI was higher in inpatients (0.62%) than outpatients (0.03%). CONCLUSION: Although there are limitations regarding study quality and the number of participants, we systematically estimated the risk of HILI in Korea. We anticipate this study would be a helpful information for prescribing herbal medicines and researching the safety of herbs.

Allogenic Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells Are More Effective Than Bone Marrow Aspiration Concentrate for Cartilage Regeneration After High Tibial Osteotomy in Medial Unicompartmental Osteoarthritis of Knee.

PURPOSE: The purpose of this study was to compare the outcome of cartilage regeneration between bone marrow aspirate concentrate (BMAC) augmentation and allogeneic human umbilical cord blood-derived mesenchymal stem cell (hUCB-MSCs) transplantation in high tibial osteotomy (HTO) with microfracture (MFX) for medial unicompartmental osteoarthritis (OA) of the knee in the young and active patient. METHODS: Between January 2015 and December 2019, the patients who underwent HTO and arthroscopy with MFX combined with BMAC or allogeneic hUCB-MSCs procedure for medial unicompartmental OA with kissing lesion, which was shown full-thickness cartilage defect (≥ International Cartilage Repair Society [ICRS] grade 3B) in medial femoral cartilage and medial tibial cartilage, were include in this study. Retrospectively we compared clinical outcomes, including Hospital for Special Surgery score, Knee Society Score (KSS) pain and function, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score between BMAC and hUCB-MSCs group at minimum of 1-year follow-up. Also, second-look arthroscopy was performed simultaneously with removal of the plate after complete bone union. Cartilage regeneration was graded by the ICRS grading system at second-look arthroscopy. Radiological measurement including hip-knee-ankle (HKA) angle, posterior tibial slope angle, and correction angle were assessed. RESULTS: Of 150 cases that underwent HTO with MFX combined with BMAC or allogeneic hUCB-MSCs procedure for medial unicompartmental OA, 123 cases underwent plate removal and second-look arthroscopy after a minimum of 1 year after the HTO surgery. Seventy-four cases were kissing lesion in medial femoral cartilage and medial tibial cartilage during initial HTO surgery. Finally, the BMAC group composed of 42 cases and hUCB-MSCs group composed of 32 cases were retrospectively identified in patients who had kissing lesions and second-look arthroscopies with a minimum of 1 year of follow-up. At the final follow-up of mean 18.7 months (standard deviation = 4.6 months), clinical outcomes in both groups had improved. However, there were no significant differences between the IKDC, WOMAC, or KSS pain and function scores in the 2 groups (P > .05). At second-look arthroscopy, the ICRS grade was significantly better in the hUCB-MSC group than in the BMAC group in both medial femoral and medial tibial cartilage (P = .001 for both). The average ICRS grade of the BMAC group improved from 3.9 before surgery to 2.8 after surgery. The average ICRS grade of the hUBC-MSC group improved from 3.9 before surgery to 2.0 after surgery. Radiological findings comparing postoperative HKA angle, posterior tibial slope angle, and correction angle showed no significant differences between the groups (P > .05). Therefore it was found that the postoperative correction amount did not affect the postoperative cartilage regeneration results. CONCLUSIONS: We found that the hUCB-MSC procedure was more effective than the BMAC procedure for cartilage regeneration in medial unicompartmental knee OA even though the clinical outcomes improved regardless of which treatment was administered. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

A survey of herbal medicines as tumor microenvironment-modulating agents.

The tumor microenvironment (TME) is extremely complex, involving extensive interactions among stromal cells, immune cells, and signaling molecules. Therefore, an approach targeting the TME has emerged as a promising therapeutic strategy. Herbal medicines consist of multiple active compounds, which have multi-target effects. Therefore, they have been regarded as potential anticancer agents; multiple studies have explored their effects on the TME. In this review, we report the effects of 29 single herb medicines or herbal formulas on the TME, based on the findings of 64 published studies. Specifically, we describe the effects of these herbal medicines on cancer-associated fibroblasts/tumor-associated fibroblasts, tumor-associated endothelial cells, myeloid-derived suppressor cells, and tumor-associated macrophages. Among the reviewed herbal medicines, the most promising TME-modulating effects were exhibited by curcumin, DHA, EGCG, resveratrol, and silibinin; these medicines showed the ability to regulate two or more components of the TME. The findings of this review support the notion that the combination of herbal medicines with conventional anticancer therapies are likely to exhibit a clinical benefit, which should be further explored in clinical trials.

Combating Drug Resistance in Colorectal Cancer Using Herbal Medicines.

Colorectal cancer (CRC) is one of the most prevalent and lethal cancer types around the world. Most of the CRC patients are treated with chemotherapeutic drugs alone or combined. However, up to 90% of metastatic cancer patients experience the failure of treatment mostly because of the acquired drug resistance, which can be led to multidrug resistance (MDR). In this study, we reviewed the recent literature which studied potential CRC MDR reversal agents among herbal medicines (HMs). Among abundant HMs, 6 single herbs, Andrographis paniculata, Salvia miltiorrhiza, Hedyotis diffusa, Sophora flavescens, Curcuma longa, Bufo gargarizans, and 2 formulae, Pien Tze Huang and Zhi Zhen Fang, were found to overcome CRC MDR by two or more different mechanisms, which could be a promising candidate in the development of new drugs for adjuvant CRC chemotherapy.

Differential expression of microRNAs in the saliva of patients with aggressive periodontitis: a pilot study of potential biomarkers for aggressive periodontitis.

PURPOSE: The aim of this study was to compare microRNA (miRNA) gene expression in saliva using miRNA polymerase chain reaction (PCR) arrays in healthy and aggressive periodontitis (AP) patients. METHODS: PCR arrays of 84 miRNAs related to the human inflammatory response and autoimmunity from the saliva samples of 4 patients with AP and 4 healthy controls were performed. The functions and diseases related to the miRNAs were obtained using TAM 2.0. Experimentally validated targets of differentially expressed miRNAs were obtained from mirTarBase. Gene ontology terms and pathways were analyzed using ConsensusPathDB. RESULTS: Four downregulated miRNAs (hsa-let-7a-5p, hsa-let-7f-5p, hsa-miR-181b-5p, and hsa-miR-23b-3p) were identified in patients with AP. These miRNAs are associated with cell death and innate immunity, and they target genes associated with osteoclast development and function. CONCLUSIONS: This study is the first analysis of miRNAs in the saliva of patients with AP. Identifying discriminatory human salivary miRNA biomarkers reflective of periodontal disease in a non-invasive screening assay is crucial for the development of salivary diagnostics. These data provide a first step towards the discovery of key salivary miRNA biomarkers for AP.

Synergistic hepatoprotective effects of CGplus on CCl4-induced acute injury.

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Chinese/Korean medicine suggests "blood stasis ()", "stagnation of vital energy ()" and "dampness and Phlegm ()" as the main etiologies of liver disorders, and multiherbal formulas are generally believed to exert synergistic action. AIM OF THE STUDY: The present study aimed to investigate the synergistic hepatoprotective effects of CGplus (a mixture of Salviae miltiorrhiza, Artemisia iwayomogi and Ammomum xanthioides) compared to those of the individual herbs. METHODS AND MATERIALS: A total of fifty-six male Balb/C mice were randomly divided into eight groups and were administered water (normal and CCl4 groups), 100 mg/kg S. miltiorrhiza, A. iwayomogi, or A. xanthioides, 50 or 100 mg/kg CGPlus or dimethyl dimethoxybiphenyl dicarboxylate (DDB) as a positive control for 4 consecutive days. After a single CCl4 injection (i.p., 10 mL/kg of 0.2% CCl4 in olive oil), blood and liver tissues were collected after 18 h of fasting for serum biochemistry, histopathological examination and molecular analyses. RESULTS: CCl4 injection induced drastic hepatic injury characterized by a more than 30-fold increase in the release of AST and ALT into the serum. These alterations were significantly attenuated by pretreatment with each of the three herbs, while the effects of the individual herbs were synergistically augmented by CGPlus pretreatment. The synergistic hepatoprotective actions of CGPlus were demonstrated consistently by analyses of oxidative stress (oxidative stressors, oxidation products and antioxidant enzymes), pro-/anti-inflammatory cytokines (TNF-ɑ, IL-1ß, IL-6, IL-10), and apoptosis (caspase-3, p53 and BAX) and histopathology. CONCLUSIONS: These data suggest that CGPlus exerts its hepatoprotective effects in a synergistic manner, and further studies are required for clinical application using other chronic models.

Anterior Cervical Debridement and Fusion for Cervical Pyogenic Spondylodiscitis: Use of Anterior Cervical Plating or Not?

STUDY DESIGN: Retrospective multicenter case series. OBJECTIVE: We sought to evaluate the safety and efficacy of anterior cervical plating in anterior cervical debridement and fusion (ACDF) for patients with cervical pyogenic spondylodiscitis (CPS). SUMMARY OF BACKGROUND DATA: Due to concerns about bacterial seeding on the foreign material after instrumentations in pyogenic infections, the safety and efficacy of anterior cervical plating for CPS are still undetermined and controversial. Little information is available about the safety and efficacy of anterior cervical plating to manage CPS. METHODS: Twenty-three patients who underwent ACDF with (n = 12) or without (n = 11) plating for CPS were included. The mean age was 62.6 years. Medical records were reviewed and radiological parameters including segmental height, segmental angle, C2-C7 angle, and fusion status were analyzed. The mean follow-up period after surgery was 21.3 months. RESULTS: After ACDF with plating, segmental height, segmental angle, and C2-C7 angle were significantly improved compared with preoperative conditions and remained well-maintained at the last follow-up. After ACDF without plating, three radiological parameters were also initially improved compared with preoperative condition, but significantly deteriorated to preoperative levels at the time of the last follow-up. The fusion rate was higher in the ACDF with plating group compared with the ACDF without plating group (90.9% vs. 63.6%; P < 0.01). One patient who received ACDF with plating and four patients who received ACDF without plating underwent revision surgery due to nonunion or bone graft dislodgement. No recurrence of pyogenic spondylodiscitis occurred in either group. CONCLUSION: ACDF with plating showed better surgical outcomes compared with ACDF without plating for CPS. We recommend the use of anterior cervical plating, which can provide biomechanical stability, for better healing of CPS. To our knowledge, this is the largest surgical case series of CPS. LEVEL OF EVIDENCE: 4.

Recovery from hepatitis A after Korean medicine-based treatment : a case report.

BACKGROUND: Many studies reported that Korean medicine (KM) is effective for treating liver disease, including hepatitis A. However, KM, specifically with herbal medicine (Chungganplus, CGP) has not been reported yet. We aimed to report a patient with hepatitis A who was treated with KM including CGP, acupuncture, and moxibustion for 12 days. METHODS: A 39-year-old man with hepatitis A who was hospitalized for 12 days after being admitted to our hospital with abdominal pain, diarrhea and vomiting. We prescribed CGP three times a day, with acupuncture performed twice daily and moxibustion at conception vessel (CV)-12 once a day. Follow-up blood tests have been done 4 times during the admission in order to access the effect of the treatment. RESULTS: In 12 days the symptoms had disappeared and the blood test results improved steadily. His AST level have declined from 1,189 IU/L to 44 IU/L, ALT from 2,423 IU/L to 127 IU/L, r-GTP from 1,347 IU/L to 339 IU/L, ALP from 384 IU/L to 205 IU/L, and total bilirubin from 3.6 mg/dL to 0.89 mg/dL. CONLCUSIONS: This case suggests that KM-based treatment using CGP may be effective for hepatitis A with no adverse effect. Further research and clinical trial on CGP would be needed to make the basis more valid.

Outcomes of simultaneous high tibial osteotomy and anterior cruciate ligament reconstruction in anterior cruciate ligament deficient knee with osteoarthritis.

BACKGROUND: We aimed to evaluate clinical and radiological results after simultaneous open-wedge high tibial osteotomy (HTO) and anterior cruciate ligament (ACL) reconstruction in patients with ACL deficiency combined with medial uni-compartmental osteoarthritis (OA) and varus deformity. METHODS: This retrospective study was performed using data collected from 2005 to 2011 on a total of 24 patients who were diagnosed with ACL injury and medial unicompartmental OA with varus deformity, and who subsequently underwent simultaneous open-wedge HTO and arthroscopic ACL reconstruction. The mean follow-up duration was 5.2 years. For clinical outcomes, we evaluated Lysholm score, Tegner activity score, range of motion, Lachmann test, and pivot-shift test, and for radiological outcomes, we evaluated the degree of varus deformity, progression of medial OA, tibial posterior slope, anterior instability, and postoperative complication. RESULTS: There were no limitations in range of motion found in any cases. Three patients showed progressive osteoarthritis on the medial compartment. The mechanical femorotibial angle was significantly corrected from varus 7.0 degrees to valgus 1.2 degrees, and the tibial posterior slope was not significantly changed. The Lysholm and Tegner activity scores were significantly improved after surgery (from 58 to 94 points on the Lysholm scale and from 4.0 to 5.3 points on the Tegner activity scale). Although the Lachman test and the pivot-shift test showed significant improvements after surgery, instability greater than Gr II was observed in three patients on the Lachman test and in four patients on the pivot-shift test. The side-to-side difference improved from 9.6 mm to 4.2 mm postoperatively as assessed using a Telos® arthrometer. There were no cases of nonunion or fixation loss. CONCLUSIONS: Simultaneous open-wedge HTO and ACL reconstruction in patients with ACL injury with medial compartmental OA showed satisfactory functional outcomes and postoperative activity level scores. However, some patients showed residual instability and progression of OA.
