Objective To determine in vitro drug susceptibility to five antifungal agents of clinical Cryptococcus neoformans strains isolated from different areas of China in recent ten years. Methods Eighty clinical isolates of Cryptococcus neoformans were isolated from Shanghai, Guangdong, Fujian, Beijing and some other areas of China from 1998 to 2007. The minimal inhibitory concentrations (MIC) of the isolates to five antifungal agents, including amphotericin B, fluconazole, flucytosine, itraconazole and voriconazole, were determined using broth microdilution procedure (document M27-A2) recommended by the Clinical and Laboratory Standards Institute (CLSI). Kruskal-Wallis rank sum test was employed for the statistical analysis. Results The MIC50 of the Cryptococcus neoforrnans isolates tested for amphotericin B, fluconazole, flucytosine, itraconazole and voriconazole were 0.5, 4, 2, 0.25 and ≤0.031 3 mg/L, respectively; and the MIC<,90> of the isolates tested for the above antifungal agents were 1, 8, 4, 0.5 and 0.062 5 mg/L, respectively. Among the tested isolates, 3 (3.8 %) were resistant to flucytosine, 4 (5.0 %) were resistant to itraconazole. All isolates were susceptible to amphotericin B and voriconazole. There was no significant difference in MIC of the strains isolated from any particular years to the five agents (χ2=0.500,2.687,2.211, 2.660,0.677,P>0.05). Conclusions The Cryptococcusneoformans isolates are highly susceptible to the five antifungal agents, while a few strains are resistant to flucytosine or itraconazole. The drug susceptibilities of the strains isolated from particular years are similar.

OBJECTIVETo compare the difference in clinical efficacy on children attention deficit hyperactivity disorder (ADHD) between the combined therapy of scalp acupuncture and EGG biofeedback and the simple EEG biofeedback therapy so as to search the better therapeutic method for ADHD.

METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the simple EEG biofeedback therapy was adopted. In the observation group, on the basis of biofeedback therapy, scalp acupuncture was added and applied to Dingzhongxian (MS 5), Dingpangyixian (MS 8), Baihui (GV 20), Sishencong (EX-HN 1), etc. The ten treatments made one session. After four sessions of treatment, FIQ value in Wechsler intelligence scale, CIH score in Conners children behavior questionnaire, the ratio of 0 wave and p wave in EEG, FRCQ and FAQ in the integrated visual and auditory continuous performance test (IVA-CPT) and clinical comprehensive efficacy were observed before and after treatment in the two groups separately.

RESULTSThree cases were dropped out in the observation group and 2 cases were out in the control group. In the two groups, FIQ, FRCQ and FAQ were all increased after treatment (P < 0.01, P < 0.05); the increases in the observation group were much more significant than those in the control group after treatment (all P < 0.05). In the two groups, CIH score and the ratio of 0 wave and p wave were all reduced after treatment (P < 0.01, P < 0.05); the reduction in the observation group were much more apparent as compared with those in the control group (both P< 0.05). The total effective rate was 91.5% (43/47) in the observation group and better than 83. 3% (40/48, P < 0.01) in the control group.

CONCLUSIONThe combined therapy of scalp acupuncture and EEG biofeedback achieves the superior efficacy on children ADHD as compared with the simple biofeedback therapy. This combined therapy rapidly relieves the essential symptoms of ADHD and improves EEG waveform in children patients. Importantly, this therapy obtains and consolidates the significant efficacy.

OBJECTIVETo investigate a new operation of breast reduction for gynecomastia.

METHODSIn the past 5 years we treated 42 cases (80 sites) of gynecomastia with the double-ring incision, a supra-lateral derma-mammary pedicle of the nipple and areola and the tumescent technique.

RESULTSThe tumescent anesthesia was effective. The operation was easily performed with slight injury and less bleeding. It was safe and the patients recovered quickly. 100 to 500 grams tissue was resected from one breast. There have been no severe postoperative complications, such as nipple or areola necrosis. Follow-up from 3 to 48 months showed satisfactory results except that there was mild scar hypertrophy on the incision around the areola.

CONCLUSIONSThe new operation for gynecomastia with the double-ring incision, a supra-lateral derma-mammary pedicle of the nipple and areola, and the tumescent anesthesia is a good, reliable and convenient technique.

OBJECTIVETo evaluate whether or not intracytoplasmic sperm injection (ICSI) can improve previous fertilization limitation on conventional in vitro fertilization (IVF).

METHODSOne hundred and thirty-six completed cycles in 113 patients with ICSI treatment were grouped. Group 1 was 106 cycles perform ICSI because of male factor, and group 2 was other 30 cycles with the history of fertilization failure and fertilization rate < 20% on conventional IVF, also assembling the cycles in group 2 according to the fertilization rate.

RESULTSThere was no significant difference between two groups in the rates of normal fertilization(70.49% vs 72.02%), good quality embryos (38.28% vs 38.81%), and clinical pregnancy (40.57% vs 40.00%) (P > 0.05). The fertilization rate of a majority of cycles (70.00%, 21/30) in group 2 was higher than 50%, and the mean of fertilization rates was 79.79%.

CONCLUSIONICSI can improve the fertilization limitation following IVF during previous cycles, and the fertilization rates was similar to those treated ICSI because of male factor.

OBJECTIVETo treat the comminute distal radius fractures by improved splint, and obersve the curative effect and compare the radiology with the traditional splint.

METHODSNinety-two patients with distal radius comminute fracture were randomly divided into two groups. There were 38 males and 54 females. The average age was 63 years old ranging from 23 to 82. Acording to AO classification on the distal fracture of the radius, there were 15 cases of A3, 40 cases of C1, 26 cases of C2 and 11 cases of C3. After all patients were treated by manipulative reduction, 46 cases of the treatment group were fixed supra-carpometacarpal joints by improved splint and trapezoid pad, the other 46 cases of control group were treated with the traditional spilint. Both groups were regularly taken X-ray recheck and changed dressings to obtain the clinical cicatrization. Patients were guided to do functional exercise after splints were taken off. Six weeks later all patients were evaluated the curative and radiologic effect according to Gartland-Werlley wrist score and Lidstrom grade respectively.

RESULTSAccording to wrist score,there were 13 cases on excellent, 34 cases on fine and 9 cases on normal in treatment group, which average score was (4.0 +/- 2.6) and the percent of wrist functional fitness was 80.6%. There were 9 cases on excellen, 19 cases on fine and 18 cases on normal in control group, which average score was (6.0 +/- 4.2) and the percent of wrist grad and 4 cases on the third grade in treatment group. There were 22 cases on the first grade, 16 cases on the second grad and 8 cases on the third grade in control group.

CONCLUSIONThe outcome of improved splint was better than that of traditional splint on the function and radiology for treating the comminute distal radius fracture.

OBJECTIVETo study the therapeutic effect of ventilation tube insertion in the middle ear and the external auditory canal on chronic secretory otitis media in children.

METHODSA retrospective study on 30 patients (40 ears) with chronic secretory otitis media and who underwent the operation of middle ear exploration and ventilation tube insertion in the middle ear and the external auditory canal was performed. Poor tympanic membrane, even with adhesion, was seen in 23 ears. Ten patients had evidence of bilateral secretory otitis media. From this group one ear was first injected with drugs (dexamethasone, mucosolvin, etc) and then tube insertion into the auditory tube was performed; the other ear only received drug injections into the auditory tube. The remaining 20 patients who had evidence of unilateral secretory otitis media only received drug injections into the auditory tube.

RESULTSThe tubes inserting into the auditory tube all dropped out 5-8 days after operation. None of the ventilation tubes into the middle ear dropped out and the patients' tympanum recovered after the ventilation tubes were removed (6-8 months after operation). The total cure rate was 87.5% (35/40) and the improvement rate was 12.5% (5/40). The operation of inserting tubes into the auditorytube did not improve the therapeutic effects. In the 0.5-2 years postoperative follow-up, middle ear effusions recurred in one ear, and three ears were transferred from type C to type A.

CONCLUSIONSThe surgery of ventilation tube insertion in the middle ear and the external auditory canal for chronic secretory otitis media can prevent the tympanic membrane from damage and dropping out of the ventilation tube and reduce recurrence in children. It is a preferred selection for the patients with poor tympanic membrane or adhesive tympanic membrane. It is no use to insert the tube into the auditory tube for the improvement of therapeutic effects.
