AIM:To investigate the effect of diquafosol sodium(SD)eye drops combined with sodium hyaluronate eye drops on improving tear film stability after wearing orthokeratology lenses.METHODS:Prospective study. A total of 82 patients(82 right eyes)who were recruited from the outpatient department of Anhui Aier Eye Hospital from March to August 2022. Participants were assigned to three groups: sodium hyaluronate(SH)group(30 eyes), SD group(24 eyes), and sodium diquafosol combined with sodium hyaluronate(CG)group(28 eyes)according to random number table method. All groups wore the same brand of orthokeratology lens. Non-invasive tear breakup time(NIBUT), non-invasive tear meniscus height(NITMH)and lipid layer thickness were examined before treatment, and after wearing orthokeratology lens for 1 d, 1 wk, and 1 mo. Corneal spot staining was also recorded.RESULTS:The NITMH and NIBUT of CG group and the SD group at 1 mo after treatment were higher than those before wearing lenses(both P<0.05), and the NIBUT and NITMH of the CG group were 19.74±3.29 s and 0.30±0.05 mm, respectively, which were better than those of the SD group(NIBUT: 16.09±2.98 s, NITMH: 0.22±0.08 mm)and the SH group(NIBUT: 15.67±3.90 s, NITMH: 0.22±0.04 mm; all P<0.01). There were no significant differences in lipid layer thickness between the groups(all P>0.05). The incidence of corneal staining did not differ significantly among the groups(P>0.05).CONCLUSION:The combination of diquafosol sodium and sodium hyaluronate eye drops demonstrates a superior effect in improving NIBUT and NITMH after wearing orthokeratology lenses for 1 mo, effectively enhancing tear film stability in patients wearing orthokeratology lenses.

Safety of modified radical prostatectomy by transperineal injection of sodium hyaluronate to the Dirichlet gap: an animal experiment / 现代泌尿外科杂志

【Objective】 To explore the safety of transrectal ultrasound-guided transperineal injection of sodium hyaluronate to expand the Dirichlet gap in laparoscopic radical prostatectomy. 【Methods】 A total of 14 healthy male purebred beagle dogs were selected and randomly divided into 2 groups, with 7 in either group.The control group was treated with conventional laparoscopic radical prostatectomy, while the experimental group was treated with laparoscopic radical prostatectomy after 2.5 mL sodium hyaluronate was injected into the Dirichlet gap under the guidance of transrectal ultrasound.The total operation time, prostate separation time, intraoperative blood loss and rectal status of the 2 groups were observed. 【Results】 After the injection of sodium hyaluronate into the Dirichlet gap between the prostate and the rectum, no rectal tissue was found in the prostate, and no obvious damage was found in the posterior rectum in either groups.The postoperative hemoglobin (HGB) was [(118.70±2.56) g/L vs.(122.10±2.19) g/L, P=0.02]; the total operation time was [(141.40±9.80) min vs.(119.10±9.16) min, P<0.05]; the prostate separation time was [(24.99±1.75) min vs.(16.64±2.34) min, P<0.05]; the amount of bleeding was [(47.43±4.32) mL vs.(34.86±5.18) mL, P<0.05] in the control group and experimental group. 【Conclusion】 Laparoscopic radical prostatectomy performed after 2.5 mL of sodium hyaluronate injection into the Dirichlet gap under the guidance of transrectal ultrasound can shorten the total operation time, the separation and resection time of the prostate, and reduce the amount of bleeding, which can improve and reduce the incidence of rectal injury, and prove the feasibility of this approach for prostatic cancer.

Objective:To investigate the clinical efficacy of recombinant human epidermal growth factor combined with sodium hyaluronate eye drops in the treatment of cataracts after multifocal intraocular lens implantation and its effect on inflammation factors in tears and tear film stability.Methods:A total of 86 patients with cataracts who underwent multifocal intraocular lens implantation at Jinan 2 nd People's Hospital from July 2020 to January 2023 were included in this randomized controlled study. These patients were randomly divided into a control group and a combined group, with 43 patients in each group. Patients in the control group were administered sodium hyaluronate eye drops postoperatively, while patients in the combined group received a combination of recombinant human epidermal growth factor and sodium hyaluronate eye drops. All patients were treated for 1 month. Before and after treatment, the levels of inflammatory factors in tears, tear film stability-related indicators, and corneal endothelial cells were measured and compared between the two groups. Additionally, any adverse reactions experienced by the patients were recorded throughout the treatment period. Results:After treatment, the levels of interleukin-6 and tumor necrosis factor-α in the tear fluid of the combined group were (17.91 ± 2.45) μg/L and (72.14 ± 8.43) μg/L, respectively. These values were significantly lower than those in the control group, which were (24.63 ± 3.05) μg/L and (86.97 ± 9.85) μg/L, respectively ( t = 11.26, 7.50, both P < 0.001). Additionally, the fluorescein staining score for corneal damage in the combined group was (2.34 ± 0.37) points. This was significantly lower than the score of (3.42 ± 0.48) points observed in the control group ( t = 11.69, P < 0.001). Tear break-up time and Schirmer I Test in the combined group were (8.68 ± 0.96) seconds and (9.31 ± 1.04) mm/5 minutes, respectively. These values were significantly higher than those in the control group, which were (7.81 ± 0.89) seconds and (7.14 ± 0.86) mm/5 minutes, respectively ( t = -4.36, -10.54, both P < 0.001). Furthermore, the corneal endothelial cell density and the proportion of hexagonal cells in the combined group were (2 514.09 ± 259.31) counts/mm 2 and (41.67 ± 5.05)%, respectively. These values were significantly higher than those in the control group, which were (2 244.82 ± 253.37) counts/mm 2 and (36.75 ± 4.96)% in the control group ( t = -4.87, -29.45, both P < 0.001). The incidence of adverse reactions in the combined group was 11.63% (5/43), which was significantly higher than 6.98% (3/43) in the control group ( χ2 = 0.55, P > 0.05). Conclusion:The combination of recombinant human epidermal growth factor with sodium hyaluronate eye drops following multifocal intraocular lens implantation in patients with cataracts effectively decreases the levels of inflammatory factors in tear fluid. This treatment regimen also enhances tear film stability, promotes the repair of injured corneal tissue, and is highly safe.

No adverse drug reactions occurred during the treatment. During the follow-up period (8 months or shorter) , no recurrence of ocular lesions was observed. Conclusion:Without topical antibiotics, oral minocycline hydrochloride combined with topical sodium hyaluronate eye drops is still effective for the treatment and prevention of recurrence of ocular lesions in patients with severe ocular rosacea.

Comparison of platelet-rich plasma and sodium hyaluronate in treatment of rotator cuff injury / 中华创伤骨科杂志

Objective:To compare the clinical effects of platelet-rich plasma (PRP) and sodium hyaluronate on rotator cuff injury.Methods:From February 2022 to December 2022, 226 patients with rotator cuff injury caused by military training were treated at Department of Orthopaedics, Jinling Hospital, School of Medicine, Nanjing University. They were all male, aged (24.5±3.7) years, and their time from injury to treatment was (4.6±2.2) months. They were divided into 2 even groups according to different treatments: an observation group of 113 cases into whose subacromial space PRP was injected, and a control group of 113 cases into whose subacromial space sodium hyaluronate was injected. In both groups, the injection was performed once a week for consecutive 3 weeks. The 2 groups were compared in terms of visual analogue scale (VAS) and Constant-Murley shoulder function scale (CMS) before treatment and 4 and 8 weeks after treatment, and the levels of TNF- α and IL-6 in the shoulder synovial fluid before treatment and 8 weeks after treatment. Results:There was no statistical difference between the 2 groups in general clinical data before treatment, indicating comparability ( P>0.05). At 4 and 8 weeks after treatment, compared with the pre-treatment values, the VAS scores were significantly decreased and the Constant-Murley scores significantly increased in both groups ( P<0.001). At 4 and 8 weeks after treatment, the VAS scores in the observation group (3.1±0.9 and 1.5±0.5) were significantly lower than those in the control group (3.7±0.8 and 2.3±0.6) while the Constant-Murley scores in the observation group (58.6±4.5 and 72.2±4.1) significantly higher than those in the control group (55.2±5.3 and 67.8±5.0) ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the 2 groups were significantly lower than the levels before treatment ( P<0.001). At 8 weeks after treatment, the levels of TNF- α and IL-6 in the observation group [(2.9±0.9) μg/L and (0.8±0.2) μg/L] were significantly lower than those in the control group [(4.0±0.4) μg/L and (1.1±0.4) μg/L] ( P<0.001). Conclusion:Injection of PRP or sodium hyaluronate can relieve pain and improve shoulder function obviously in patients with rotator cuff injury, but PRP is superior to sodium hyaluronate in the treatment of rotator cuff injury.

No grade 3-4 side effects occurred in all patients, and there were no common grade 1-2 rectal side effects such as diarrhea, rectal bleeding, proctitis and anal pain, etc. Only one patient developed grade 1 constipation during radiotherapy. Conclusion:Injection of Chinese made cross-linked sodium hyaluronate isolation gel can significantly reduce the irradiated volume of rectum and the incidence of rectal toxicities in prostate cancer patients undergoing radical radiotherapy.

Effect of sodium hyaluronate eye drops combined with tobramycin, dexamethasone and pranoprofen eye drops in the treatment of dry eye after phacoemulsification

Purpose: To investigate the clinical effect of sodium hyaluronate eye drops combined with tobramycin, dexamethasone, and pranoprofen eye drops in the treatment of dry eye after phacoemulsification. Methods: Medical records of 188 patients with dry eye after phacoemulsification, treated in our hospital from August 2020 to August 2021, were included and divided into groups based on the type of dry eye treatment. Patients in the control group (n = 90) were treated with tobramycin, dexamethasone, and pranoprofen eye drops. Patients in the test group (n = 98) were treated with sodium hyaluronate, tobramycin, dexamethasone, and pranoprofen eye drops. The tear secretion test (TST), film rupture time (BUT), corneal fluorescence staining (FS) score, levels of interleukin (IL)?6, and tumor necrosis factor (TNF)?? before the treatment and at 1 month follow?up, the overall total effective rate and the number of completely cured cases were compared between the two groups. Multiple linear regression was used to calculate coefficients for predicting clinical variables. Ordinal logistic regression was used to compute coefficients and odds ratios for predicting effective scores. Results: The total effective rate in the observation group (99%) was significantly higher than that in the control group (80.00%). After the treatment, the TST and BUT indexes of the observation group were higher compared to the control group, and the FS score of the observation group was lower than that of the control group. TNF?? and IL?6 levels of the observation group were lower compared to the control group. Logistic regression analysis demonstrated that the differences in the effective rate and clinical variables between the two groups remained significant after adjusting for the effect of age. Conclusion: A combination of sodium hyaluronate, tobramycin, dexamethasone, and pranoprofen eye drops for the treatment of dry eye after phacoemulsification can improve the curative effect, reduce corneal fluorescein staining and inflammatory factor index levels compared to the treatment regimen lacking sodium hyaluronate eye drops.

Objective:To explore the therapeutic effect of sodium hyaluronate combined with glucosamine sulfate in the treatment of knee osteoarthritis.Methods:A total of 90 outpatients and inpatients with knee osteoarthritis who visited the Department of Orthopedics and Traumatology, Daishan County Hospital of Traditional Chinese Medicine from January to June 2020 were selected, and they were divided into sodium hyaluronate group (control group) and sodium hyaluronate combined with glucosamine sulfate group (observation group) by random number table method, with 45 patients in each group. Visual analog scale (VAS) score was used to evaluate the changes of pain in the two groups before treatment, 5 weeks and 6 months after treatment, respectively; at the same time, the total effective rate of 5 weeks and 6 months after treatment was compared between the two groups.Results:Before treatment, there was no significant difference in VAS scores [(7.4 ± 1.5) vs (7.3 ± 1.7) points] between the two groups ( t = 0.24, P = 0.812); at 5 weeks [(5.3 ± 1.1) vs (4.1 ± 1.2) points] and 6 months after treatment [(4.0 ± 0.8) vs (3.2 ± 0.9) points], the VAS scores of the observation group were significantly lower than those of the control group, and the differences were statistically significant ( t = 5.54, 5.32, P < 0.001). Compared with the same group before treatment, VAS scores were lower in the two groups at 5 weeks and 6 months after treatment, and the differences were statistically significant ( P < 0.05). At 5 weeks after treatment, there was no significant difference in the total effective rates [44.4% (20/45) vs 48.9% (22/45)] between the two groups (χ 2 = 0.18, P = 0.672); at 6 months after treatment, the total effective rate of the observation group (91.1%, 41/45) was significantly higher than that of the control group (66.7%, 30/45), and the difference was statistically significant (χ 2 = 8.07, P = 0.004). Conclusion:Sodium hyaluronate combined with glucosamine sulfate can significantly reduce the pain in patients with knee osteoarthritis, the total effective rate is higher, and is better than the effect of sodium hyaluronate alone.

Effects of Fluorometholone combined with sodium hyaluronate eye drops in the treatment of xerophthalmia and the influence on inflammatory factors in tears / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To investigate the effects of fluorometholone combined with sodium hyaluronate eye drops in the treatment of xerophthalmia and the influence on inflammatory factors in tears. <p>METHODS: A prospective randomized controlled study was conducted in 116 patients(232 eyes)with xerophthalmia who were treated between February 2017 and December 2019. They were randomly divided into observation group and control group, 58 cases(116 eyes)in each group. The control group was treated with sodium hyaluronate eye drops, while the observation group was treated with 0.1% fluorometholone eye drops based on the treatment for the control group. Ocular Surface Disease Index(OSDI)scoring was carried out before treatment and after 2wk and 4wk of treatment. The tear film break-up time(BUT), Schirmer I test(SⅠt)and corneal fluorescent staining(FL)scores were measured. The tear meniscus height(TMH)and noninvasive keratograph tear breakup time(NIKBUT)were determined by eye surface comprehensive analyzer. Conjunctival impression cytology was performed to determine epithelial cell grading score and goblet cell density. Levels of interleukin 1β(IL-1β), interleukin -6(IL-6)and transforming growth factor β1(TGF-β1)in tears were determined. Meanwhile, efficacy and safety were evaluated.<p>RESULTS: The overall response rates of the observation group and the control group were 94.8% and 82.8%(<i>P</i><0.05). The observation group had higher SⅠt, BUT and NIKBUT, lower FL scores and OSDI scores than the control group at 4wk(<i>P</i><0.05). The goblet cell density was higher in the observation group than in the control group at 4wk(<i>P</i><0.05). IL-6 and IL-1β in the observation group were significantly lower than those in the control group at 2wk and 4wk, and TGF-β1 was significantly higher than that in the control group at 4wk(<i>P</i><0.05). The incidences of adverse reactions in the two groups were 3.4% and 1.7%(<i>P</i>>0.05).<p>CONCLUSION: Fluorometholone combined with sodium hyaluronate can significantly improve clinical symptoms as well as tear film stability in patients with xerophthalmia, which may be related to regulating effect on ocular surface inflammatory factors.

Comparison on dry eye symptoms and stability of tear film after correction of myopia by LASIK versus LASEK with the use of artificial tears / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM:To investigate the dry eye symptoms and the stability changes of tear film after correction of myopia by laser-assisted <i>in situ</i> keratomileusis(LASIK)and laser epithelial keratomileusis(LASEK)with the use of 0.1% sodium hyaluronate(HA).<p>METHODS:A total of 230 myopia patients(460 eyes)were divided into LASIK group and LASEK group from February 2017 to December 2017. Each operation group was randomly assigned to 0.1% HA treatment subgroup and HA-free subgroup. Both subgroups were instructed to apply gatifloxacin(0.3%)and loteprednol(0.5%)after the corneal refractive surgery. The changes of dry eye symptom score, corneal perceptual reaction, corneal fluorescein staining(FL), basic Schirmer Ⅰ test(SⅠt)and tear film break-up time(BUT)were observed in different time points.<p>RESULTS:There were significant differences in FL, dry eye symptom score and corneal perceptual response between the 0.1% HA treatment group and HA-free group at 1wk, 1, 3 and 6mo after operation both in LASIK and LASEK patients(<i>P</i><0.05). BUT after operation in each group was significantly deceased at 1wk compared with preoperative level. Other observation time points after surgery of BUT and each postoperative level of SⅠt were still within the normal range although lower than the preoperative levels. The subjective symptoms of dry eyes, tear film stability and corneal surface perception of LASEK patients were better than LASIK patients especially at 1wk, 1 and 3mo after surgery.<p>CONCLUSION:These two kinds of refractive surgery may cause different degrees of dry eye symptoms. These symptoms in the LASEK group were lighter than that in the LASIK group in the early postoperative period. The early adequate use of preservative-free 0.1% HA could effectively promote the corneal repair and be greatly helpful for postoperative dry eye symptoms.
