Effect of sodium hyaluronate combined with rehabilitation training on knee joint injury caused by golf

BACKGROUND In high-intensity sports like golf,knee joints are prone to injury,leading to pain,limited mobility,and decreased quality of life.Traditional treatment methods typically involve rehabilitation exercises,but their effectiveness may be limited.In recent years,sodium hyaluronate has emerged as a widely used biomedical material in the treatment of joint diseases.AIM To explore the effect of sodium hyaluronate combined with rehabilitation training on pain degree,flexion range of motion and motor function of knee joint injured by golf.METHODS Eighty patients with knee joint injury caused by golf were randomly divided into control(group B)and observation group(group A).The group B was treated with rehabilitation training,and the group A was treated with sodium hyaluronate combined with rehabilitation training.The clinical efficacy,range of motion and function of knee joint,quality of life and inflammatory factors were compared.RESULTS The excellent and good rate of rehabilitation in the group A was raised than group B.At 6 weeks and 3 months after treatment,the range of motion of the two groups was raised than that before treatment,and that of the group A was raised than group B.After treatment,the scores of Lysholm and International Knee Documentation Committee(IKDC)in the group A were raised,and those in the group A were raised than group B.The VAS score of the two groups was reduced than that of the group B,and the SF-36 score of the group A was reduced than group B.The interleukin(IL)-1β,IL-8 and tumor necrosis factor-αin the two groups were reduced,and those in the group A were reduced than group B.CONCLUSION Sodium hyaluronate combined with rehabilitation training has a good clinical effect in the treatment of patients with knee joint injury caused by golf,which relieve pain,maintain knee joint function and improve patients'life quality.

Efficacy of recombinant human epidermal growth factor plus sodium hyaluronate eye drops in diabetic dry eye post-cataract surgery

BACKGROUND Dry eye syndrome(DES)after diabetic cataract surgery can seriously affect the patient’s quality of life.Therefore,effective alleviation of symptoms in patients with this disease has important clinical significance.AIM To explore the clinical effect of recombinant human epidermal growth factor(rhEGF)plus sodium hyaluronate(SH)eye drops on DES after cataract surgery in patients with diabetes.METHODS We retrospectively evaluated 82 patients with diabetes who experienced DES after cataract surgery at Tianjin Beichen Hospital,Affiliated Hospital of Nankai University between April 2021 and April 2023.They were classified into an observation group(42 cases,rhEGF+SH eye drops)and a control group(40 cases,SH eye drops alone),depending on the different treatment schemes.The therapeutic efficacy,dry eye symptom score,tear film breakup time(TFBUT),basic tear secretion score[assessed using Schirmer I test(SIt)],corneal fluorescein staining(FL)score,tear inflammatory markers,adverse reactions during treat-ment,and treatment satisfaction were compared between the two groups.RESULTS Therapeutic efficacy was higher in the observation group compared with the control group.Both groups showed improved TFBUT and dry eye,as well as improved SIt and FL scores after treatment,with a more pronounced improvement in the observation group.Although no marked differences in adverse reactions were observed between the two groups,treatment satisfaction was higher in the observation group.CONCLUSION rhEGF+SH eye drops rendered clinical benefits to patients by effectively ameliorating dry eye and visual impairment with favorable efficacy,fewer adverse reactions,and high safety levels.Thus,this treatment should be promoted in clinical practice.

Purification and Characterization of Hyaluronate Lyases Produced by Two Types of Bacteria

Hyaluronate lyases were obtained from two types of naturally isolated bacterial strains Paenibacillus yunnanensis and Paennarthrobacter nicotinovorans.PyHL(form P.yunnanensis)in the culture supernatant of the bacteria was purified by two steps of column chromatography.The enzyme showed the molecular mass of 74 kDa by SDS-PAGE and the maximal activity at pH 5.0,35℃.PyHL maximally degraded hyaluronate by an endo-type manner,and showed low degradation activity toward chondroitin sulfates.Dermatan sulfate was not the substrate.PnHL(from P.nicotinovorans)in the culture supernatant of the bacteria was purified by two steps of column chromatography.The enzyme showed the molecular mass of 70 kDa by SDS-PAGE and the maximal activity at pH 6.0,30℃.Genomic analysis of P.nicotinovorans on the bases of the internal amino acid sequences of PnHL.

A Comprehensive Review of Long-Term Safety and Effectiveness of FACILLE Modified Sodium Hyaluronate Gel for Injection over 3 Years

FACILLE modified sodium hyaluronate gel was designed to be used for nasolabial fold (NLF) correction. However, no study has investigated the long-term safety and effectiveness of FACILLE. Thus, a retrospective study of 14 aesthetic clinics in China was conducted. This was the first large-scale, postmarketing study on FACILLE to evaluate the occurrence of adverse events (AEs) and provide essential information on the satisfaction of patients with FACILLE injections. This study recruited participants aged >18 years. FACILLE was injected into the NLFs on both sides of each participant’s face. The primary endpoint for safety was systemic or severe AEs at an injection site. Effectiveness was assessed on the basis of the participants’ subjective perceptions and satisfaction levels. Safety and effectiveness data were collected on the day of injection and at 2 weeks and 1, 3, 6, 9, 12, 18, 24, 30 and 36 months postinjection. In total, 1552 participants were enrolled (mean age, 29.1 years), and most of them (96.5%) were women. The mean injection volume was 1.39 ± 0.658 mL, and the average number of injections was 2.4 ± 1.68. AEs were reported by 205 participants (13.2%). All AEs occurred at local injection sites. No systemic or severe AEs were observed. Local pain was the most frequently reported AE regardless of the number of injections or the injection volume. Only eight AE cases were correlated with FACILLE administration, with two cases involving local allergic reactions. The participants self-reported that they perceived the procedure to have an effectiveness of ≥90% within 6 months postinjection although this percentage decreased substantially after 9 months. Their satisfaction level was >90% within 1 month postinjection but decreased gradually after 3 months. Our results indicate that the long-term safety of FACILLE injection is adequate. The high self-reported perceived effectiveness and satisfaction levels indicate the considerable potential of FACILLE injections for correcting NLFs.

Efficacy and safety of 0.4 percent sodium hyaluronate for endoscopic submucosal dissection of gastric neoplasms

AIM:To evaluate the efficacy and safety of sodium hyaluronate solution(SH) in endoscopic submucosal dissection(ESD) of gastric neoplasms.METHODS:A prospective multicenter randomized,double blind,controlled trial was designed and utilized in this study.A total of 76 patients with 5-20 mm sized gastric neoplasms were enrolled at three academic hospitals in South Korea from June 2011 to October 2011.Patients were randomly assigned to the 0.4% sodium hyaluronate or control groups.All lesions underwent endoscopic ESD.ESD was performed with 0.4%SH and normal saline(NS) solution for submucosal injection.Efficacy was assessed using en bloc resection and the number of additional injections.Secondary evaluation variables were the volume of injection material,steepness of mucosal elevation,bleeding rate,procedural time and operator satisfaction.Finally,the safety was assessed by analyzing adverse events during the study.RESULTS:The usefulness rate in the 0.4%SH group and the controlled group had statistically significant difference under intention to treat(ITT) analysis(90.91% vs 61.11% P = 0.0041).Under per protocol(PP),the usefulness rate is statistically significant different(93.10% vs 61.76%,P = 0.0036).The difference in volume of the solution injected between 0.4%SH group and the controlled group and NS group was also statistically significant under intention to treat and per protocol analysis(ITT:0.03 ± 0.02 mL vs 0.06 ± 0.03 mL,P = 0.0003,PP:0.03 ± 0.02 mL vs 0.06 ± 0.03 mL,P = 0.0004).Satisfaction above the grade good was significantly higher in the SH group under intention to treat and per protocol analysis(ITT:90.91% vs 61.11%,P = 0.0041,PP = 93.11% vs 61.77%,P = 0.0022).Adverse events above grade 3 were not noticed in either group.All adverse events were treated and were judged as not associated with the submucosal injection solutions.CONCLUSION:0.4%SH solution is a safe and effective agent that doesn't cause any significant adverse events and is useful for submucosal injection during ESD.

Low concentration of sodium hyaluronate temporarily elevates the tear film lipid layer thickness in dry eye patients with lipid deficiency

AIM： To investigate the effects of different concentrations of artificial tears on lipid layer thickness （LLT） and blink rate （BR） in dry eye patients. METHODS： This study included 106 eyes of 58 patients with dry eye. The lipid deficiency type was defined as the LLT baseline 〈75 nm. The LLT and BR were measured at baseline and 1, 5 and 15min after the instillation of 0.1% or 0.3% sodium hyaluronate （SH） eye drops by using the LipiView ocular surface interferometer. RESULTS： In the lipid deficiency group, the LLT increased from baseline at 1rain post instillation. The LLT after the instillation of 0.1% SH was significantly higher than that after the instillation of 0.3% SH （P〈0.001）. The LLT returned to baseline at 15min post instillation of 0.1% SH and at 5min post instillation of 0.3% SH. In the non-lipid deficiency group, the LLT decreased from baseline at lmin and returned to baseline at 5rain for both treatments. The BRs were not significantly different at different time points for both treatments. CONCLUSION： SH eye drops induce a short-term increase in LLT of patients with lipid deficiency. A low concentration of artificial tears have a stronger effect than a high concentration of artificial tears on the increase in LLT. in comparison, SH eye drops induce a transient and slight decrease in LLT of patients without lipid deficiency. A low concentration of artificial tears might be better for patients with lipid deficiency.

In vitro effects of sodium hyaluronate on the proliferation and the apoptosis in chondrocytes from patients with Kashin-Beck disease and osteoarthritis

Objective：To identify the in vitro effects of sodium hyaluronate（HA） on the proliferation and the apoptosis of chondrocytes from patients with Kashin-Beck disease（KBD） and osteoarthritis（OA）. Methods：Samples of articular cartilages from KBD and OA patients, as well as healthy volunteers（6 subjects in each of the 3 groups） were dissected, digested with collagenase and the cells cultured in monolayers. Chondrocytes from each sample were assigned to an untreated group and two HA-treated groups： H0（no HA）, H100（HA, 0.1 g/L） and H500（HA, 0.5 g/L）. The first passage chondrocytes were used to observe proliferation using the MTT assay, and apoptosis by flow cytometry through Annexin V/PI staining. Results：HA promoted proliferation of chondrocytes in all the three groups, and.in KBD and OA groups, for cells cultured for 4 and 6 days, H500 significantly promoted the cell proliferation. The apoptotic rates of both KBD and OA group chondrocytes were in the order H500 〈 HA100 〈 H0. Conclusion：Sodium hyaluronate administration has a dosedependent in vitro effect to promote proliferation and inhibit apoptosis of chondrocytes from patients with KBD and OA.

Determination of sodium hyaluronate in pharmaceutical formulations by HPLC–UV

A liquid chromatography （HPLC） method with UV detection was developed for determination of sodium hyaluronate in pharmaceutical formulation. Sodium hyaluronate is a polymer of disaccharides, composed of D-glucuronic acid and D-N-acetylglucosamine, linked via alternating 13-1, 4 and D-l, 3 glycosidic bonds. Being a polymer compound it lacks a UV absorbing chromophore. In the absence of a UV absorbing chromophore and highly polar nature of compound, the analysis becomes a major challenge. To overcome these problems a novel method for the determination of sodium hyaluronate was developed and validated based on size exclusion liquid chromatography （SEC） with UV detection. An isocratic mobile phase consisting of buffer 0.05 M potassium dihydrogen phosphate, pH adjusted to 7.0 using potassium hydroxide （10%） was used. Chromatography was carried out at 25 ~C on a BioSep SEC $2000, 300 mm ~ 7.8 mm column. The detection was carded out using variable wavelength UV-vis detector set at 205 nm. The compounds were eluted isocratically at a steady flow rate of 1.0 mL/min. Sodium hyaluronate retention time was about 4.9 min with an asymmetry factor of 1.93. A calibration curve was obtained from 1 to 38 g/mL （r〉0.9998）. Within-day % RSD was 1.0 and between-day % RSD was 1.10. Specificity/selectivity experiments revealed the absence of interference from excipients, recovery from spiked samples for sodium hyaluronate was 99-102. The developed method was applied to the determination of sodium hyaluronate in pharmaceutical drug substance and product.

Determination of sodium hyaluronate with some basic bisphenylnaphthylmethane dyes by resonance Rayleigh scattering method

In an acetic acid–sodium acetate buffer solution of pH 3.6–6.8, a compound complex was formed between sodium hyaluronate (abbreviated as SH) and some basic bisphenylnaphthylmethane dyes, leading to a great enhancement of the intensity of resonance Rayleigh scattering (RRS) and giving a new RRS spectrum, with its maximum scattering peak near 280 nm. It was also found that the intensity of RRS was directly proportional to the concentration of SH near the range between 0 and 3.0 mg/L. Based on these facts, a sensitive method for the determination of SH has been established. The method had good selectivity, and has been used for the determination of total amounts of SH in samples with satisfactory results. For the NB–SH system, the detection limit of SH was down to 13.7 ng/mL.

Anti-scarring effect of sodium hyaluronate at filtration pathway after filtering surgery in rabbits

AIM: To investigate the anti-scarring effect of sodium hyaluronate(HA) at filtration pathway after filtering surgery in a rabbit model.METHODS: Fifteen healthy adult New Zealand white rabbits were selected for trabeculectomy in both eyes. The right eyes were used as HA group with 0.1 m L HA injected into the anterior chamber at the end of the operation;the left eyes were used with 0.1 m L sodium lactate Ringer’s solution(RS) injected into the anterior chamber as RS group. Intraocular pressure(IOP), filtering blebs morphology, inflammatory reaction and complications were observed at the 7, 60, and 90 d after surgery.RESULTS: One day after surgery, the IOP of HA and RS groups were 12.75±1.92 and 10.50±1.59 mm Hg(P=0.005). At the 7;day postoperative, the filtering blebs of each group were functional type and TGF-β expression was significantly difference in both groups(0.10±0.01 vs 0.14±0.02, P=0.024). After 60 d of the operation, all filtering blebs were scarring and alpha-smooth muscle actin(α-SMA) expression was significantly difference in both groups(0.40±0.04 vs 0.35±0.02, P=0.032). α-SMA positive cells were mainly distributed in the junction of conjunctiva and sclera and around the blood vessels. The collagen volume fraction(CVF) of HA and RS group was(75.49±7.01)% and(79.93±5.35)%(P=0.044). On the 90;day after the operation, CVF was(82.57±5.19)% and(88.08±1.75)% in HA and RS groups(P=0.036). There was no α-SMA positive cell in HA group, while a few positive cells were observed in RS group(P=0.000).CONCLUSION: HA has effect of anti-scar and antiinflammation on filtration pathway after filtering surgery within 3 mo by inhibiting fibroblast proliferation and collagen deposition.

Hyaluronate Increases Polynucleotides Effect on Human Cultured Fibroblasts

The HA is present in almost all vertebrates and plays a critical role in tissue development and cell proliferation, it has been demonstrated to promote wound healing and involved in angiogenesis and inflammation. Also polynucleotydes (PN) have proved to promote the “in vitro” growth and activity of human fibroblasts and osteoblasts, to increase reparation on UVB damaged dermal fibroblasts and seems to promote proliferation of human pre-adipocytes. Several in vivo studies have demonstrated the PN effect also in vivo, inducing an increase of angiogenesis and healing process. In this paper we have evaluated the effect of a mixture of Polynucleotides (PN) and entire Hyaluronic Acid (HA) on cultured human fibroblasts by analyzing cell growth. Different mixture have been tested and it has been demonstrated that the presence of HA even at low concentration (1 mg/ml) determine an increase of PN activity up to 20%. Furthermore, the addition of HA 1 mg/ml to PN 100 μg/ml induces a cell growth rate comparable to that exerted by PN concentration of 12 μg/ml.

The effectiveness of local anesthetic and sodium hyaluronate injection for the posterior disc displacement: A case report

Posterior disc displacement of the temporomandibular joint is rare. We present a unique treatment method and magnetic resonance (MR) images of this condition. The patient was a 43-year-old male with a chief complaint of abnormal occlusion. Regarding the present status, there was no occlusion on the right side. No temporomandibular joint pain, myalgia, or clicking were observed while mouth opening. On MR images, the posterior disc displacement without reduction on the right was observed and it was assumed that occlusal abnormality was due to this condition. We treated him with the following methods. After injection into the superior articular cavity with 2% lidocaine, a sodium hyaluronate preparation was injected followed by intermaxillary traction applied using rubber. The recovery of occlusion was confirmed in follow-up at 5 days after treatment. In the 13th days, the intermaxillary traction was removed. On MR images, the right disc condition was changed to anterior disc displacement with reduction. We consider our treatment methods are effective for this clinical condition.

Treatment of Hip Trochanteric Bursitis Using Hyaluronate Injections

Trochanteric bursitis is a common cause of musculoskeletal pain and often requires medical intervention and should be distinguished from sciatica and irradiating pain of pelvic and spinal origin. Previously, the etiology of the trochanteric pain syndrome was thought to be caused by inflammation. The current study was performed in order to assess the efficacy of trochanteric injections. Methods: 158 patients were treated for trochanteric bursitis (132 females/26 males, range 22 - 88 years). 59b were treated with corticosteroid injection, 60 with hyaluronate and 39 were injected using a combination of both. Patients were followed by the HOOS score for a minimum of 12 months. Results: Pre-operative HOOS scores were similar in all groups. Following injection, the HOOS score increased from 27 ± 4 to 66 ± 2 after six months and 77 ± 4 after a year. At 12-month follow-up, the average score of patients treated by corticosteroids injection was 44 ± 7 compared with 62 ± 8 for the hyaluronate injected group and 64 ± 6 for the combination injection group. Discussion: It appears that injection therapy is highly efficacious for treating trochanteric bursitis. The effect of hyaluronate or hyaluronate and steroid combination appears to be longer lasting than that of steroid alone.
