AIM: To comprehensively investigate the current status of cataract surgery in Leshan city, and find the existing problems according to the survey results as a guide to cataract prevention and treatment in future.
METHODS: We surveyed the status of cataract surgery containing equipments, surgeons and surgery conditions in 17 ophthalmology departments of general hospitals from Leshan including 6 counties, 1 county-level city and 4 districts during 2012. Cataract surgery methods, according to various surgery financial resources, surgical performances and surgical incision, were divided into phacoemulsification and intraocular lens implantation ( Phaco + IOL ) , extracapsular cataract extraction and intraocular lens implantation ( ECCE + IOL ) , and each method contained 2 groups. We analyzed the outcomes following preoperative examination, surgeons, surgical methods, surgical equipments, types of IOL, surgical quantity, surgical results, and intraoperative complication.
RESULTS: In whole city there were 16 operating microscopes, 43 slit lamp microscopes, 12 non-contact tonometers, 1 intraocular lens Master, 8 optical A/B type ultrasonic examination systems, 4 YAG lasers and 12 phacoemulsification instruments. There 15 doctors could complete cataract surgery independently, and 5 of them were phacoemulsification surgeons. The total number of completed cataract surgeries reached 6 211 eyes, containing 3 564 eyes for Phaco+IOL ( 57%) ( preoperative visual acuity ≥0. 3 in Phaco+IOL1 were 1 520 eyes, 24%) and 2 647 eyes for ECCE+IOL ( 43%) ( 1 533 eyes in ECCE+IOL1, 25%). In various groups, off-blindness rate was 94. 80%-100%, off-disability rate was 90. 41%-100%, and 94. 96% - 100% received intraocular lens implantation, intraoperative complication rate was 1. 00%-15. 10%.
CONCLUSION: The distribution of surgeons and equipments in the whole city is unbalanced, and the utilization rate of phaco equipment is low. The levels are different in various hospitals on surgical technique, surgical quantity and surgical results. Phacoemulsification and intraocular lens implantation is considered as the main therapy for cataract, and as a transition to dioptric and personalized cataract surgery. The surgical condition of the city is good, but the proportion of cataract surgery for prevention of blindness in Leshan city is low, and the surgical technique remains to be further improved.

Objective: To evaluate the eruption of mandible third molar in orthodontic patients with non-extraction or extraction of the lower premolars. Methods: We selected 3 group of the orthodontic patients. One group consisted of 23 subjects (12 males, 11 females, average age 13.5 years) with non-extraction. One group consisted of 23 subjects (12 males, 11 females, average age 13 years) with lower first premolar extraction. One group consisted of 21 subjects (11 males, 10 females, average age 14.07 years) with lower second premolar extraction. The panoramic radiography was taken. The lower third molar angulation and eruption space were measured before and after the orthodontic treatment. The comparison of treatment changes in 3 groups were performed by means of a paired-sample t test using SPSS 17.0 software package. Results: The RS, LS, Rratio and Lratio increased significantly after treatment in patients with lower first premolar extraction(P<0.01). The RM3 and LM3 increased(P<0.05) and RS, LS, Rratio and Lratio increased significantly(P<0.01) after treatment in patients with lower second premolar extraction(P<0.05). Conclusion: The mandibular third molars show improvement in eruption space and inclination in the orthodontic patients with lower premolar extraction.

OBJECTIVETo examine the effect of ONO-AE3-208, an EP4 antagonist, on the formation of bone metastasis from prostate cancer in mice.

METHODSThirty-four 6-week old nude mice were divided into an experimental and a control group of equal number to be treated by intraperitoneal injection of ONO-AE3-208 and double distilled water, respectively. Then PC3/LUC cells were constructed by stably transfecting luciferin to prostate cancer PC3 cells and inoculated into the left ventricle of the mice to establish an animal model of systemic bone metastasis. The time of metastasis formation, photon tumor burdens, and changes of the survival curves after modeling were compared between the two groups of mice.

RESULTSAt 30 days after modeling, bioluminescence imaging analysis showed that the photon tumor burdens were significantly increased in a time-dependent manner in the control group in comparison with those in the experimental group (P < 0.01). The rate of metastasis formation was significantly higher in the former than in the latter (93.3% vs 33.3%, P < 0.001). The median time of metastasis formation was 29 d (95% CI 26.547 - 35.262) in the experimental animals as compared with 21 d (95% CI 17.213 -24.787) in the controls (P < 0.001).

CONCLUSIONEP4 antagonist ONO-AE3-208 can inhibit the formation of bone metastasis from prostate cancer in mice.

AIM: To evaluate the effects of the extract of Buddleja officinalis eye drops in basic tears secretory volume, tear film stability, expression of androgen receptors(AR) in castrated rats with dry eye, and to investigate the therapeutic effects of extract of Buddleja officinalis on dry eye caused by gonadal hormones level imbalance. METHODS:A total of 45 Wistar masculinity rats were divided at random into 9 groups, including normal group(A1,A2 and A3), model group(B1,B2 and B3), therapy group with extract of Buddleja officinalis eye drops(C1,C2 and C3). The "1" stood for being fed for 1 month, and "2" for 2 months, and "3" for 3 months. The dry eye model was established with orchiectomy on group B,C. Group C was treated with Buddleja officinalis extract eye drops for one month. All rats were checked with Schirmer Ⅰ test (SⅠt) and tear film break-up time (BUT). Expression of AR was analyzed by flow cytometer(FCM). RESULTS:The SⅠt value of group C was significantly higher than that of group B (P<0.01) and the BUT value of group C was significantly longer than that of group B (P<0.01), which indicated the eye drop could significantly keep basic tears secretory volume and tear film stability. And the expression of AR of group C was much higher than that of group B,which showed that available composition of the eye drops maybe display androgen-like activity.CONCLUSION:The main components of extract of Buddleja officinalis is the flavonoids which could significantly inhibit happening of dry eye of rat after androgen level lowered. Its mechanism is like androgen's and it could display androgen-like activity to keep basic tears secretory volume and tear film stability.

In MAST (mRNA accessible site tagging),the DNA tags from synthesized library were employed for identifying mRNA accessible sites. A large number of tags were amplified and subcloned for sequencing to verify mRNA binding profiles. A PCR was designed by using one primer which bridges over the tag terminal sequences. In PCR reaction DNA tag fragments were concatemerized by a bridge primer in reaction cycles. The concatemerized tag fragments were subcloned and sequenced. Dozens of the concatemerized sequences contained thousands tags. The PCR was a simple,effective way which for sequencing tags in a high through put manner.
