AIM: To analyze the postoperative infection of pathological myopia with pocket scleral reinforcement. ·METHODS:The clinical data of 167 cases of pathological myopia treated with pocket scleral reinforcement in June to December 2014 were analyzed. The postoperative infection rate, the resistance of pathogenic bacteria were analyzed, and the related factors of infection were analyzed. ·RESULTS: A total of 286 eyes were obtained in 167 patients. The infection rate was 6. 3% in 10 patients ( 18 eyes) . There were 30 pathogenic bacteria isolated from the 18 infected eyes, in which were 10 Staphylococcus aureus, 10 Staphylococcus epidermidis, 6 Klebsiella pneumoniae, 4 Pseudomonas aeruginosa infection. Gram positive bacteria showed higher resistance to penicillin, ampicillin and ciprofloxacin, and were sensitive to vancomycin. The resistance rates of gram negative bacteria to cefotaxime were higher, but to imipenem was low. The two groups of patients age, culture level, operation time, the number of operation, intraoperative nursing staff seniority, postoperative medication compliance rate was statistically significant (P<0. 05), which related to the infection after pocket scleral reinforcement. ·CONCLUSION:The infection caused by Staphylococcus aureus is the most common after pocket scleral reinforcement, and it is sensitive to vancomycin, and gram negative bacteria is sensitive to imipenem. Shortening the operation time, using the experienced nursing staff to cooperate, reducing the number of operation and improving the compliance of the patients can reduce the postoperative infection.

Objective: To determine the role of intensity of plum-blossom needle tapping in treating alopecia areata.Methods: The BALB/c mice were randomized into a normal group, a control group, a roller-needle (RN) group, a mild plum-blossom needle (MP) group, and a heavy plum-blossom needle (HP) group. An area of hair was removed by external application of 8% sodium sulfide on BALB/c mice. The hair regrowth, hair follicle changes, and local inflammatory factor changes after cutaneous acupuncture were observed.Results: After treated with sodium sulfide, the hair was completely removed, the local hair follicles reached the catagen phase, and the expressions of interleukin (IL)-1α, IL-1β, IL-2, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, and IL-17 were increased. Mice intervened by RN achieved the same hair growth rating as the controls but with thicker hair shafts; mice in the MP group had incomplete and uneven hair growth but thicker hair shafts; mice in the HP group didn't show hair growth. Pathological analysis revealed significant inflammatory infiltration into the local follicle bulbs and increased catagen-phase follicles in the control group, while RN and MP groups showed significantly increased anagen-phase follicles, coarser individual hairs, and obvious hair shafts. Meanwhile, most of the hair follicles in the HP group were in telogen phase and showed obvious surrounding inflammatory infiltration. RN, MP, and HP significantly down-regulated the increased IL-2, IL-1α, IL-1β, TNF-α, and IFN-γ levels (P<0.05), but didn't notably affect the increased CD34 expression (P>0.05).Conclusion: Cutaneous acupuncture with heavy stimulation intensity can inhibit hair growth in hair removal mice, while RN, with the lightest stimulation intensity, is unlikely to affect hair growth but may make hair shafts thicker and follicles larger.
