AIM:To examine the efficacy and safety of cryotherapy in the management of Fusarium corneal ulcer.
METHODS: Retrospective contract analysis of the clinical data of 41 patients ( 41 eyes ) who infected with Fusarium corneal ulcer. All of them underwent focal lesion keratectomy combined with amniotic membrane transplantation between January 2010 and May 2013. The cryotherapy treatment group of 22 cases (22 eyes), non-cryotherapy group of 19 cases ( 19 eyes ) . All the cases were followed up for 3 ~12mo. We analyzed the healing of corneal ulcer, corneal neovascularization, postoperative visual acuity, complications and ulcer recurrences.
RESULTS: There were no significant difference for the two groups at the cure rate and the recovery rate, the corneal neovascularization and postoperative visual acuity (P>0. 05). The total effective rate and corneal healing time in cryotherapy group was significantly higher than that in non - cryotherapy group ( P < 0. 05 ). The postoperative visual acuity of two group were higher than that of preoperatively ( P < 0. 05 ). There was no complication occurred in cryotherapy group while there was 1 patient of secondary glaucoma in non-cryotherapy group.
CONCLUSION: Cryotherapy is an effective and safe method for the treatment of Fusarium corneal ulcer.

OBJECTIVETo compare the therapeutic effects between close reduction and plaster slab fixation combined with plaster external traction and operation for the treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications.

METHODSFrom June 2009 to June 2012, 151 children with closed Gartland III supracondylar humerus fractures were retrospectively studied and divided into two groups, including 87 boys and 64 girls, ranging in age from 1 to 12 years old with an average of 5.3 years old. Among them, 76 children (conservative group) were treated with close reduction and plaster slab fixation combined with plaster external traction; 75 children (operation group) underwent surgical operation. The time of elbow joint function exercise, the healing time of fracture, the function recovery of elbow joint and carrying angle was recorded and analyzed. The therapeutic effects were evaluated by the Flynn criteria system.

RESULTSAll patients were followed up from 6 to 36 months (18.3 months on average). The average time of fracture healing and elbow joint functional exercise of the conservative group was shorter than those of operation group (P < 0.001). Motion range of the elbows and carrying angle of two groups were no statistical difference (P > 0.05). According to Flynn criteria system, in conservative group, the result was excellent in 31 cases, good in 35, fair in 7, and poor in 3; in operation group, 27 in excellent, 30 in good, 17 in fair and 1 in poor; there was no significant difference between two groups in therapeutic effects (P > 0.05).

CONCLUSIONClose reduction and plaster slab fixation combined with plaster external traction in treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications,which has similar effect to surgical treatment, and the time of fracture healing and elbow joint function exercise are significantly shorter.

AlM: To observe the influence on the incidence of diffuse lamellar keratitis ( DLK ) after laser in situ keratomileusis ( LASlK ) whether or not wearing sterile gloves with talc during operation, and to confirm the role of residual talc in the occurrence of DLK.
METHODS: Totally 563 patients ( 1 126 eyes ) accepted operation with the method of surgical hand antisepsis only were set as the experimental group, while 592 patients ( 1 184 eyes ) with the method of surgical hand antisepsis and sterile gloves as the control group. Each patient was rechecked to observe the occurrence of DLK on the first day and the seventh day after the operation. Then the data of DLK were statistically analyzed byχ2 test and rank sum test.
RESULTS:On the first postoperative day, the incidence of DLK was 7. 4% (83 eyes) in experimental group and 12. 2% (144 eyes) in control group. ln the former group, stage Ⅰ of DLK accounted for 4. 6% (52 eyes) and stageⅡ for 2. 8% (31 eyes);while in the latter, stage l did for 7. 7% (91 eyes) and stageⅡfor 4. 5% (53 eyes). On the seventh day, all DLK were cured. The other 2 cases ( 3 eyes) occurred in stage Ⅳ DLK ( the first time recheck was on the eighth day after operation and fluorometholone ophthalmic solution was not used on time ) . The incidence and the severity were both significant lower in the experimental group than in the control (both P<0. 01).
CONCLUSlON: Talc is one of the most important factors resulting in DLK after LASlK. The method of surgical hand antisepsis without wearing gloves could avoid the stimulation of talc and reduce the incidence of DLK obviously.

Objective To construct PPAR?and PPAR?response element (PPRE)-controlled luciferase expression vectors,and to determine whether the traditional Chinese medicine emodin activates PPAR?and improves the glucose uptake by HepG2 hepatocytes.Methods (1) PPAR?and PPRE luciferase expression vectors were constructed and were applied to screen more than 20 ingredients of the traditional Chinese medicine. (2) HepG2 cells were incubated with emodin which can activate PPAR?and PPRE luciferase activity,and the PPAR?mRNA expression level was evaluated by RT-PCR/Southern blot.(3) PPAR?and glucose transporter 2 (Glut2) proteins were determined by Western blot analysis in HepG2 cells treated with emodin.(4) The glucose uptake rate was measured using 2-deoxy-[~3H]-D-glucose in HepG2 cells after treatment with emodin.Results (1) Emodin stimulated luciferase activity controlled by PPRE in dose-dependent manner at concentrations of 0.04 to 180?mol/L in COS-7 cells.The highest value was about 4 folds of control in the cells treated with 90?mol/L emodin (P

OBJECTIVETo explore the influence of obstructive sleep apnea hypopnea syndrome (OSAHS) in children on the secretion of antidiuretic hormone (ADH).

METHODSThirty pediatric patients with OSAHS were examined with polysomnography (PSG) and urinary volume was recorded during sleep, and vein blood was sampled in deep sleep to detect the level of ADH in serum using radioimmunoassay technique, which were performed before and after adenotonsillectomy. Among twenty heath children were also detected the secretion of ADH as normal controls.

RESULTSAfter surgery, apnea-hypopnea index (AHI) decreased (from 17.4 +/- 2.6 to 3.3 +/- 1.4, t = 27.68, P < 0.001), lowest SaO2 increased (from 0.783 +/- 0.134 to 0.954 +/- 0.062, t = 6.45, P < 0.001). The level of ADH in OSAHS patients (63.1 +/- 35.2) ng/L was much lower than that in health children (85.1 +/- 22.2) ng/L (t = 2.75, P < 0.01). The serum ADH level in postoperative patients (83.1 +/- 21.2) ng/L was increased significantly compared with that of preoperative (t = 2.56, P < 0.05), and no statistical difference versus that of health children (t = 0.17, P > 0.05). Nycturia volume of preoperative OSAHS children (492 +/- 90) ml was significant higher than that of postoperative (332 +/- 56) ml or normal controls (346 +/- 62) ml (t was 7.85 and 6.43, both P < 0.001). There was no significance in nycturia volume between postoperative group and control group (t = 0.77, P > 0.05).

CONCLUSIONSAfter adenotonsillectomy in children with OSAHS caused by adenotonsillar hypertrophy, the sleep pattern and ADH secretion could become normal.

The influence of low tube voltage in dual source CT (DSCT) coronary artery imaging on image quality and radiation dose and its application value in clinical practice were investigated. Totally, 300 cases of chest pain with low body mass index (BMI <18.5 kg/m(2)) subjected to DSCT coronary artery imaging were prospectively enrolled. The heart rate in all patients were greater than 65/min. The retrospective ECG gated scanning mode and simple random sampling method were used to assign the patients into groups A, B and C (n=100 each). The patients in groups A, B and C experienced 120-, 100-, and 80-kV tube voltage imaging respectively, and the image quality was evaluated. The CT volume dose index (CTDIvol) and dose length product (DLP) were recorded, and the effective dose (ED) was calculated in each group. The image quality scores and radiation doses in groups were compared, and the influence of tube voltage on image quality and radiation dose was analyzed. The results showed that the excellent rate of image quality in groups A, B and C was 95.69%, 94.72% and 96.33% respectively with the difference being not statistically significant among the three groups (P>0.05). The CTDIvol values in groups A, B and C were 51.35±12.21, 21.28±7.13 and 6.34±3.34 mGy, respectively, with the difference being statistically significant (P<0.05). The ED values in groups A, B and C were 9.27±1.63, 4.56±2.29 and 2.29±1.69 mSv, respectively, with the difference being statistically significant (P<0.05). It was suggested that for the patients with low BMI, the application of DSCT coronary artery imaging with low tube voltage can obtain satisfactory image quality, and simultaneously, significantly reduce the radiation dose.
