OBJECTIVE: To investigate the clinical efficacy of oral medicine and sodium hyaluronate in prevention of intrauterine adhesions after artificial abortion.
 METHODS: A total of 572 patients with early pregnancy termination through artificial abortion, who experienced two or more times of abortion, were retrospectively analyzed. Patients were randomly and voluntarily divided into 4 groups: an artificial cycle group, a drospirenone and ethinylestradiol tablets group, a sodium hyaluronate group, and a control group. The thickness of the endometrium, return time of menses, and the status of intrauterine adhesions were observed.
 RESULTS: The thickness of the endometrium in the artificial period group was greater than that in the control group (P<0.001). It was less in the drospirenone and ethinylestradiol tablets group comparing with that in the control group (P<0.001). There was no significant difference in the thickness of the endometrium between the sodium hyaluronate group and the control group (P=0.717). Return time of menses in the artificial menstrual cycle group and the drospirenone and ethinylestradiol tablets group was shorter than that in the control group (P<0.001). There was no significant difference in return time of menses between the sodium hyaluronate group and the control group (P=0.813). The incidence of intrauterine adhesions could be reduced by the 3 preventive measures (All P<0.01).
 CONCLUSION Drugs for artificial cycle and drospirenone and ethinylestradiol tablets medication immediately after artificial abortion can effectively promote endometrial repair and reduce the incidence of intrauterine adhesions. However, for the patients with poor compliance, drospirenoneand ethinylestradiol tablets are the first choice for prevention of intrauterine adhesion.

OBJECTIVETo assess the safety and efficacy of hyaluronic acid-based gel of non-animal origin (NASHA gel [Restylane]; Q-Med AB, Uppsala, Sweden)for correcting nasolabial folds in Chinese.

METHODSPatients with moderate or severe nasolabial fold (Wrinkle Severity Rating Scale, WSRS) were recruited to receive NASHA gel injection ( < 1.5 ml). The patients were followed up for 6 months. The efficacy was assessed by physicians and patients, respectively. Adverse events (AEs) were recorded and laboratory tests were performed before and after operation.

RESULTS86 patients were treated. 6 months after injection, improved esthetic results was assessed by patients and physicians independently. 52 AEs happened in 32 cases (37.2%). Most of them were local injection reaction and minor, which were recovered spontaneously. No systemic reaction was found.

CONCLUSIONSNASHA gel can improve the nasolabial folds. It is very safe and tolerated.

BACKGROUNDLong-term use of benzalkonium chloride (BAC)-preserved drugs is often associated with ocular surface toxicity. Ocular surface symptoms had a substantial impact on the glaucoma patients' quality of life and compliance. This study aimed to investigate the effects of sodium hyaluronate (SH) on ocular surface toxicity induced by BAC-preserved anti-glaucoma medications treatment.

METHODSFifty-eight patients (101 eyes), who received topical BAC-preserved anti-glaucoma medications treatment and met the severe dry eye criteria, were included in the analysis. All patients were maintained the original topical anti-glaucoma treatment. In the SH-treated group (56 eyes), unpreserved 0.3% SH eye drops were administered with 3 times daily for 90 days. In the control group (55 eyes), phosphate-buffered saline were administered with 3 times daily for 90 days. Ocular Surface Disease Index (OSDI) questionnaire, break-up time (BUT) test, corneal fluorescein staining, corneal and conjunctival rose Bengal staining, Schirmer test, and conjunctiva impression cytology were performed sequentially on days 0 and 91.

RESULTSCompared with the control group, SH-treated group showed decrease in OSDI scores (Kruskal-Wallis test: H = 38.668, P < 0.001), fluorescein and rose Bengal scores (Wilcoxon signed-ranks test: z = -3.843, P < 0.001, and z = -3.508, P < 0.001, respectively), increase in tear film BUT (t-test: t = -10.994, P < 0.001) and aqueous tear production (t-test: t = -10.328, P < 0.001) on day 91. The goblet cell density was increased (t-test: t = -9.981, P < 0.001), and the morphology of the conjunctival epithelium were also improved after SH treatment.

CONCLUSIONSSH significantly improved both symptoms and signs of ocular surface damage in patients with BAC-preserved anti-glaucoma medications treatment. SH could be proposed as a new attempt to reduce ocular surface toxicity, and alleviate symptoms of ocular surface damage in BAC-preserved anti-glaucoma medications treatment.

BACKGROUND: Arthroscopic rotator cuff repair generally has a good clinical outcome but shoulder stiffness after surgery due to subacromial adhesion is one of the most common and clinically important complications. Sodium hyaluronate (HA) has been reported to be an anti-adhesive agent in a range of surgical procedures. However, there are few reports of the outcomes of arthroscopic rotator cuff repair of the shoulder. This study examined whether a subacromial injection of HA/carboxymethylated cellulose (CMC) affected the postoperative shoulder stiffness and healing of rotator cuff repair, as well as the safety of an injection. METHODS: Between January 2008 and May 2008, 80 consecutive patients with arthroscopic rotator cuff repair were enrolled. The patients were assigned randomly to the HA/CMC injection group (n = 40) or control group (n = 40). All patients were evaluated using the visual analog scale (VAS) for pain, passive range of motion at 2, 6 weeks, 3, 6, 12 months after surgery, and the functional scores at 6, 12 months postoperatively. Cuff healing was also evaluated using CT arthrography or ultrasonography at 6 or 12 months after surgery. RESULTS: The HA/CMC injection group showed faster recovery of forward flexion at 2 weeks postoperatively than the control group but the difference was not statistically significant (p = 0.09). There were no significant difference in pain VAS, internal rotation, external rotation and functional scores between two groups at each follow-up period. The functional scores improved 6 months after surgery in both groups but there were no differences between the two groups. The incidence of unhealed rotator cuff was similar in the two groups. There were no complications related to an injection of anti-adhesive agents including wound problems or infections. CONCLUSIONS: A subacromial injection of an anti-adhesive agent after arthroscopic rotator cuff repair tended to produce faster recovery in forward flexion with no adverse effects on cuff healing. However, its anti-adhesive effects after rotator cuff repair should be considered carefully with further studies.

BACKGROUND: Septic arthritis of the knee has been reported recently in adult patients who were administered hyaluronate. We evaluated the incidence of septic knees and the utilization of hyaluronate in the Korean adult population using nationwide data from the Health Insurance Review and Assessment Service (HIRA). METHODS: All new admissions to the clinics or hospitals for septic knees were recorded in the HIRA database which was established by the Korean government and covers the Korean population using the International Classification of Diseases-10 revision code. We evaluated the incidence of septic arthritis of the knees in the population above 50 years of age. Hyaluronate prescription data was also collected from the HIRA database. RESULTS: In 2012, the incidence of septic knees was 2.7 per 100,000 persons in men and 4.2 per 100,000 persons in women, respectively. The age-adjusted incidence of septic knees increased by 6.7% per year (95% confidence interval, 3.3 to 10.1), and the annual number of prescriptions of hyaluronate increased about 1.5-fold during the study period. CONCLUSIONS: Cautious aseptic technique is required when hyaluronate is administered in adult patients with osteoarthritis of the knee due to the concerns of the risk of septic arthritis.

The Rejuran(R) is a new filler product made from purified polynucleotides. Here we present data from an animal study and a clinical trial to examine the durability, efficacy and safety of the Rejuran(R) on crow's feet. For the animal study, 25 mice were divided into three groups: Group 1 received phosphate buffered saline (PBS); Group 2 were treated with Yvoire(R); and Group 3 were treated with Rejuran(R). The durability and efficacy of each treatment were assessed by microscopy and staining. In the clinical trial, 72 patients were randomized to receive Rejuran(R) treatment for crow's feet on one side and Yvoire-Hydro(R) on the contralateral side, at a ratio of 1:1. Repeated treatments were performed every two weeks for a total of three times, over a total of 12 weeks' observation. All injections and observations of efficacy and safety were performed by the same two investigators. In the animal study, the Rejuran(R) group showed similar durability and inflammatory response to the Yvoire(R) group. Upon efficacy assessment, the Rejuran(R) group showed the greatest elasticity and collagen composition, and a significant difference in skin surface roughness and wrinkle depth. In the clinical trial, the primary and secondary objective efficacy outcome measure showed no statistical significance between the two groups, and in safety outcomes there were no unexpected adverse effects. Our data suggest that the Rejuran(R), as a new regenerative filler, can be useful to reduce wrinkles, by showing evidence for its efficacy and safety.

OBJECTIVETo study the effect of SSd on lipid peroxidation during experimental hepatic fibrosis progression.

METHODThe experimental models of hepatic fibrosis were induced by intraperitoneal injection of dimethylnitrosamine (DMN) on rats. SSd was administered by intraperitoneal injection for 4 weeks. Serum was analyzed for alanine and aspartate aminotransferase (ALT and AST), hyaluronic acid (HA), laminin (LN), collagen IV (IV-C), malonaldehyde (MDA) and superoxide dismutase (SOD) activities. Liver samples were measured for MDA contents and SOD activities in normal group, model group and SSd group.

RESULTSSd significantly decreased ALT and AST activities and lowered HA, LN and IV-C contents. It enhanced SOD activities in liver, while reduced MDA contents both in serum and liver.

CONCLUSIONSSd has obvious effects of protecting hepatocytes and resisting hepatic fibrosis, and the mechanism may be associated with its anti-lipid peroxidation effect.
