OBJECTIVE:To observe the therapeutic effects of compound glycyrrhizin combined with halometasone cream on vitiligo.METHODS:95patients with vitiligo were randomly divided into treatment group and control group.64patients in treatment group had taken compound glycyrrhizin continuously for60days at a dose of1～3tablets with3times per day,meanwhile,0.05%halometasone cream had been used locally with2times per day.While31other patients in control group had only been treated with0.05%halometasone cream with2times per day for60days.RESULTS:The efficacy rate in treatment group was62.5%as compared with32.3%in control group,there existed significant difference between the two groups(P

OBJECTIVETo observe depot medroxyprogesterone acetate (DMPA) and testosterone undecanoate (TU) injected at 8-week intervals for the suppression of spermatogenesis in healthy Chinese men.

METHODSAfter screening, 30 healthy volunteers were enrolled and randomly assigned to 3 dosage-groups (n = 10/group): 1000 mg TU (Group A), 1000 mg TU plus 150 mg DMPA (Group B), 1000 mg TU plus 300 mg DMPA (Group C). All dosages were given as intramuscular injections at 8-week intervals. The study consisted of an 8-week control (baseline) period, a 24-week treatment period and a 24-week recovery period.

RESULTSConsistent azoospermia or severe oligozoospermia was achieved and maintained in all the volunteers during the treatment period, except 2 in the mere TU group who experienced a "rebound" in sperm concentrations. An 8-week regimen of TU plus DMPA at both tested combination dosages effectively suppressed spermatogenesis to azoospermia. All volunteers tolerated the injections; no serious adverse effects were reported.

CONCLUSIONThe lower combined dosage is recommended for further testing in an expanded clinical trial or contraceptive efficacy study.

Objective:To investigate the serotype distribution and drug resistance of Streptococcus pneumoniae ( S. pneumoniae) isolated in Urumqi Children′s Hospital and to evaluate the significances of 13-valent pneumococcal conjugate vaccine (PCV13) in preventing infection and controlling drug resistance. Methods:The S. pneumoniae isolates stored in clinical laboratory of Urumqi Children′s Hospital from January to December in 2018 were re-cultured.The serotypes were detected by capsule swelling experiment to assess the coverage rate of PCV13.The minimum inhibitory concentration (MIC) of Penicillin, Amoxicillin, Cefotaxime and Ceftriaxone were detected by E-test method, and the susceptibility of the isolates to Meropenem and other 9 antibiotics was detected by VITEC 2 Compact system. Results:A total of 225 S. pneumoniae strains were identified.The common serotypes were 19F (32.9%), 23F (12.0%), 19A (10.7%), 6B (10.2%) and 6A (8.0%). PCV13 coverage rate was 80.4%.There was no significant difference in serotype distribution and PCV13 coverage between children < 2 years old and ≥ 2 years old, as well as between Han and minority people.The 57.8% and 31.7% strains showed intermediate susceptibility and resistance against oral Penicillin, respectively.Based on the breakpoints for meningitis, 89.4% strains were resistant against pare-nteral Penicillin, and 47.5% and 64.6% strains were non-susceptible (mainly intermediately susceptible) to Ceftria-xone and Cefotaxime, respectively.The resistance rates of strains against Erythromycin, Sulfamethoxazole-trimethoprim and Tetracycline were as high as 98.1%, 67.6% and 89.6%, respectively.More than 90% tested isolates were susceptible to Amoxicillin, Meropenem, Levofloxacin or Moxifloxacin.PCV13 strains were more resistant to Penicillin than non-PCV13 strains. Conclusions:The serotypes 19F, 23F, 19A, 6B and 6A are common among the S. pneumoniae isolated in Urumqi.The coverage rate of PCV13 is about 80%.There was no significant difference in serotype distribution between Han and minority nationality children. S. pneumoniae were frequently resistant against Erythromycin.The high resistance to Penicillin and other beta-lactams should be taken into account when treatment is decided for suspected pneumococcal meningitis.Universal administration of PCV13 would be effective strategy to prevent pneumococcal infection in children and to control the drug resistance of S. pneumoniae.
