AIM: To compare the effectiveness of botulinus toxin of type A and complete resection of the periorbital muscle on idiopathic blepharospasm.
● METHODS: Patients with idiopathic blepharospasm and having undergone either of two procedures from Dec. 2010 to Jun. 2015 were selected ( 60 patients ) . Among them, group A (30 patients, 60 eyes) underwent botulinus toxin of type A, group B (30 patients, 60 eyes) underwent complete resection of the periorbital muscle.
●RESULTS: ln group A, the patients with complete response, obvious response, partial response, and no response were 36(60. 0%), 20(33. 3%), 2(3. 3%) and 2 (3. 3%) cases respectively. ln group B, the patients with complete response, obvious response, partial response, and no response were 16(26. 7%), 24(40. 0), 12(20. 0%) and 8 ( 13. 3%) cases respectively. The difference was statistically significant ( Z = - 2. 968, P = 0. 003 ). The relapse rate of group A and group B were 93. 3% and 20. 0% after 6mo, the difference was statistically significant (χ2=32. 851, P<0. 001).
●CONCLUSION: The botulinus toxin injection of type A is effective for idiopathic blepharospasm. But recurrence rate is high after 6mo. Complete resection of the periorbital muscle have long-term efficacy for idiopathic blepharospasm. It′s a supplementary therapy after idiopathic blepharospasm recurrence.

OBJECTIVETo evaluate the application of shear wave elastography (SWE) combined with transition zone biopsy in the detection of prostate cancer (PCa).

METHODSA total of 489 patients with suspected PCa underwent transrectal ultrasonography (TRUS) and SWE-guided prostatic biopsy. We evaluated the role of SWE combined with transition zone biopsy in promoting the detection rate in comparison with the results of biopsy pathology.

RESULTSThe pathological results confirmed 221 malignant and 268 benign cases. Based on systematic biopsy, SWE combined with transition zone biopsy achieved a detection rate of 45. 19% , significantly higher than that of systematic biopsy alone (33.13%) (P < 0.05). The diagnostic sensitivity, specificity, and accuracy of SWE were significantly better than those of TRUS (P < 0.05). The mean elasticity (Emean) of SWE was remarkably higher for malignant than for benign lesions ([40.1 ± 9.5] vs [21.6 ± 8.3] kPa, P < 0.05). With 28.5 kPa as the threshold of the Emean value, the area under the ROC curve was 0. 899, and the diagnostic sensitivity and specificity were 88.71% and 86.23%, respectively.

CONCLUSIONSWE combined with transition zone biopsy could significantly improve the detection rate of prostate cancer.

Objective To undertake a survey on the prevalence, pathogenic factors and treatment needs of hearing impairment in children under 14 years old in Guizhou province. Methods Using the probability proportion to size (PPS) method, 2 068 children aged 0～14 years were included in the study and in 30 clusters in Guizhou province based on the WHO protocol. Results For children aged 0～14 years, the prevalence of hearing impairment was 3.48% and the prevalence of hearing disability was 1.84 %. There were statistically differences of the prevalence of hearing disability between children aged 7～ 14 years (2.66 %) and 0～ 6 years (0. 51%), and the differences also in hearing impairment between male children (4.22%) and female children (2.54%). The main causes of hearing impairment were ear diseases (50.00%), non-infective conditions (11.11%), genetic conditions (20.83 %) and unknown causes (27. 77%). 3. 58% of all subjects needed medical or surgical treatment and 2. 32% needed hearing aids. Conolusion The prevalence of hearing disability of children under 14 years old in Guizhou province was higher than that of other cities. The main cause of the hearing impairment of children was otitis media with hereditary deafness also ranked in top.

OBJECTIVE To observe the effect of administration intranasal corticosteroids on small airway disfunction for allergic rhinitis (AR) patients. METHODS AR patients with small airway disfunction were administrated intranasal corticosteroids for twelve weeks. Before treatment, nasal VAS, RQLQ were recorded, pulmonary function test were given. After therapy, VAS, RQLQ were obtained again at the 4th, 8th and 12th week. Pulmonary function test were performed at the 4th and 12th week. RESULTS VAS, RQLQ were all improved after therapy (P <0.01). The indices of FEV1/FVC%, MMEF pred%, MEF75pred%, MEF50pred%, MEF25pred%were also improved significantly (P<0.05), especially for MMEFpred%, MEF75pred%, MEF50pred% (P<0.01). CONCLUSION Small airway lesions can be obviously improved by the intranasal corticosteroids applied for AR. It has positive significance for preventing AR from developing into asthma.

Pseudomonas sp. M18, one of plant-growth-promoting rhizobacteria, can produce secondary metabolites including phenazine-1-carboxylic acid (PCA) and pyoluteorin (Plt). PA2572 gene coding protein is a probable two-component response regulator in Pseudomonas according to homologous speculations. In order to investigate its genetic function, PA2572 homologous gene, ppbR, was amplified from M18 genome, inactivated by inserting a Gm cassette. The resulting reconstruct was introduced into the M18 genome using homologous recombination technique, so as to obtain the null mutant M18P. The results showed that the M18P has less flagellar swimming and swarming motility, and yielded fewer PCA. The production of PCA was only 50% of the wild type. However, there was no remarkable difference between mutant and wild type in producing pyoluteorin in KMB medium.

AlM: To study the clinical effect of the application of microscopic pterygium resection combined with different concentration of mitomycin C ( MMC) .
METHODS:A total of 110 cases of pterygium patients (120 eyes) were randomly divided into control group (58 eyes) and observation group (62 eyes) according to the odd and even number method. The control group adopted the pterygium resection combined 0. 3mg/mL MMC, and the observation group was given pterygium resection combined 0. 2mg/mL MMC. The cure rate and the recurrence rate, eyesight before and after the treatment, two groups of cornea and sclera wound healing situation, the incidence of postoperative complications were compared.
RESULTS: The cure rate and recurrence rate of the control group was 84. 5% and 15. 5% respectively, and the observation group was 93. 6% and 6. 5% respectively, the differences were statistically significant (P<0. 05). There were statistical differences of vision of the two groups before and after treatment (P<0. 05), and there were no statistical differences of the two groups between the two groups after treatment (P>0. 05). The cornea, sclera, wound healing time of the observation group were less than the control group, and there were statistical differences between the two groups ( P < 0. 05 ). The incidence of complications was 13. 8% in the control group and 3. 2% in observation group, with statistically significant difference (P<0. 05).
CONCLUSlON: The application effect of microscopic pterygium resection combined with MMC is remarkable, and the joint of 0. 2mg/mL concentration of MMC is more safe and effective, and is worth popularizing in clinical application.

AlM: To investigate the effect of endocapsular phacoemulsification cataract extraction and intraocular lens (lOL) implantation with a 1. 8mm or 3. 0mm clear corneal incision on total root mean square ( RMS ) value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film.
METHODS:ln a prospective study, 156 age- related patients ( 196 eyes ) were randomly distributed into two groups. 1. 8mm-group comprised 94 eyes that had a silicone lOL inserted through a 1. 8mm sutureless clear corneal incision, while, 3. 0mm- group comprised 102 eyes through a 3. 0mm clear corneal incision. Postoperatively, the changes in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film at 1wk, 1 and 3mo were determined respectively.
RESULTS:ln both groups, postoperatively at 1wk,there were statistically significant differences ( P<0. 05 ) in the total RMS value of the cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film, while, there were statistically minimal differences ( P< 0. 05 ) between 1. 8mm-group and 3. 0mm-group at 1mo, but were not statistically significantly different ( P > 0. 05 ) between two groups at 3mo postoperative.
CONCLUSlON:This study confirms that incision size has strong impact on the corneal higher-order aberrations, especially, 3. 0mm incision caused significant differences in the total RMS value of cornea, corneal astigmatism, spherical aberration, coma, trefoil and tear film compared with 1. 8mm micro-incision, therefore, micro-incision is very beneficial for clinical use in phacoemulsification.

From 2006 to 2008, the susceptibility of different species of animal hosts to Campyebacter jejubni infection was observed in various areas of Jiangsu province, in which the API Campy System was used to perform the biochemical identification and the multiple PCR assay was employed to analyse the C.jejuni isolates from 3010 specimens of fouls. Cattle, pigs and monkeys, and in addition, the susceptibility of isolates to various antibiotics was also determined. In these specimens investigated 402 samples were found to be positive in the detection of C.jejuni with a positive detection rate of 13.36%. The positive detection rates in chicken, water fouls, milk cows, pigs, monkey, red crowned crane and wapiti were 15.83% (258/1630), 10.4% (52/100), 8.24% (42/510), 15.63% (25/160), 15% (15/100), 12.5% (15/80) and 0% (0/30) respectively. Meanwhile, the antibiotics to which the isolates from different hosts showed high rate of sensitivity to 27 antibiotics of 10 varieties included: chloromycetin (100%), Almocylin (99.7%), amicarcin (92.59%), cefprozil (91.67%), alchimycin (90.74%); while the antibiotics to which these isolates showed high rate of resistance were compound neoromin (99.7%), cefoperazone (99.07%), trimethoprim (97.22%), cepronatin (91.67%), cepromondo (99,07%) respectively. It is evident that the susceptibility of different hosts to C.jejuni infection and the status of drug-resistance of the isolates appear to be quite different and more complicated in Jiangsu province.
