OBJECTIVE: To explore clinical efficacy of dorsal plate assisted fixation of dorsal lunate fossa fracture block of distal radius. METHODS: From January 2019 to January 2022, 30 patients were treated with dorsal plate assisted fixation of dorsal lunate fossa fracture of distal radius, including 13 males and 17 females, aged from 42 to 68 years old with an average of (48.7±5.6) years old;According to Doi fracture classification, 24 patients were type 3 blocks and 6 patients were type 4 blocks. The degree of palmar angle of anterior and posterior distal radius was fixed by dorsal steel plate during operation. Fracture healing and functional recovery of wrist were observed after operation. Functional evaluation was performed by Gartland and Werley scoring system at 12 months after operation. RESULTS: All patients were followed up from 12 to 13 months with an average of (11.3±0.9) months. All fractures healed for 4 to 5 months with an average of(4.7±0.8) months. Median palpal inclination of anterior and posterior distal radius fixed by dorsal plate was 5.30°(4.85°, 6.03°), 12.45°(11.98°, 13.43°) respectively, and had statistical difference( P<0.01). Gartland and Werley scores was (1.1±0.4) at 12 months afteropertaion, and 27 patients got excellent result and 3 good. CONCLUSION Dorsal plate assisted fixation of dorsal lunate fossa fractures is beneficial to reduction and stabilization of displaced dorsal fractures and restoration of palmar inclination.

Objective To investigate the clinical treatment of nonpenetrated cornea trauma caused by crops. Methods Clinical data of 128 cases of nonpenetrated cornea trauma caused by crops were retrospectively analyzed. According to the interval time between occurrence of trauma and clinic visiting, the patients were divided into 3 groups:group A (33 cases,<24 h), group B (72 cases, 24 h≤interval time<1 week) and group C (23 cases, ≥ 1 week). The therapeutic effects and prognosis were analyzed. Results There was statistical difference in the incidence of corneal ulcer among group A, group B and group C: 6.1% (2/33), 62.5% (45/72) and 100.0% (23/23), χ2= 52.32, P<0.01. In group B, 12 cases were treated with conjunctival flap covering, 2 cases received keratoplasty and 2 cases undertook enucleation. In group C, 10 cases were treated with conjunctival flap covering, 4 cases received keratoplasty and 2 patients undertook enucleation finally. All the other patients were cured with local debridement and medical treatment. Conclusions Patients with nonpenetrated cornea trauma caused by crops may develop infectious keratitis, and prompt and proper treatment can avoid the secondary infection and improve the outcome. Local debridement in combination with iodophors disinfection can prevent the incidence of infectious keratitis. Conjunctival flap covering is an effective technique in the treatment of corneal ulcer caused by nonpenetrated cornea trauma.

OBJECTIVE: To analyze the effects of intradermal needling for pain and tear film stability in patients after pterygium excision. METHODS: A total of 76 patients (98 affected eyes) with primary pterygium were randomly divided into an observation group (38 cases, 53 affected eyes) and a control group (38 cases, 45 affected eyes).In the control group, only pterygium resection was performed, in the observation group, intradermal needling after pterygium resection was applied at Cuanzhu (BL 2), Yuyao (EX-HN 4), Taiyang (EX-HN 5), Sibai (ST 2), Hegu (LI 4), removed after 24 h and changed three times a week. The pain level of 3 days after surgery, dry eye symptoms, the basic tear secretion test (Schirmer-Ⅰ), and the tear-break time (BUT) changes before surgery, 2 weeks after surgery and 4 weeks after surgery were compared between the two groups, and the clinical efficacy was evaluated. RESULTS: The pain level of 3 days after surgery in the observation group was significantly lower than that in the control group (<0.05). The dry eye symptom scores at 2 weeks and 4 weeks after surgery in the two groups were significantly lower than those before surgery (all <0.05), and the dry eye symptom scores in the observation group were significantly lower than those in the control group (both <0.05). The Schirmer-Ⅰ test at 2 weeks and 4 weeks after surgery was significantly prolonged than that before surgery(all <0.05), and the Schirmer-Ⅰ test in the observation group was significantly longer than that in the control group (both <0.05). The BUT at 2 weeks and 4 weeks after surgery in the two groups was significantly longer than that before surgery (all <0.05), and the BUT in the observation group was significantly longer than that in the control group (both <0.05). The total effective rate in the observation group was 89.5% (34/38), which was higher than 71.1% (27/38) in the control group (<0.05). CONCLUSION Intradermal needling can effectively reduce the pain level of patients after pterygium resection, improve dry eye symptoms, promote the secretion of tears and improve the tear film stability.

OBJECTIVETo investigate the value of detection of hepatitis C virus core antigen (HCV-cAg) for screening blood donor by using the internal reagent enzyme immunoassay (EIA) and anti-HCV antibody.

METHODSThe first and repeat assays were performed for detection of serum anti-HCV and HCV-cAg ELISA in 3972 donor's serum specimens from August to October of 2004. Twenty-five donors positive for anti-HCV were tested with HCV-cAg EIA kits and the results were compared with the results of HCV RNA determination with RT-PCR method.

RESULTSIn 3972 donor's serum samples, only 1 serum specimen was positive for HCV RNA identification among 10 specimens which were positive for anti-HCV in first assays, and only 1 serum specimens was positive for HCV RNA identification among 12 specimens positive for anti-HCV in repeat assays, only 2 serum specimens were positive HCV RNA identification in 3 specimens which were positive for HCV-cAg assays.

CONCLUSIONThe sensitivity of HCV-cAg ELISA is similar to HCV RT-PCR, but it is much cheaper. Therefore, HCV-cAg ELISA and anti-HCV may be used together to screen blood donor.
