Background Instability of tear film,increase of ocular surface temperature and tear evaporation are the associated factors of both bubbles and dry eye.But the relationship between dry eye and ocular surface bubbles is unclear.The bubbles are easily retained and checked in the inferior conjunctiva fornix.Objective This study aimed to study the relationship between dry eye and bubbles in the inferior conjunctiva fornix.Methods Sixty-four eyes of 32 patients with binocular irritative symptoms and bubbles or without bubbles in the inferior conjunctiva fornix were collected in Affiliated Tianyou Hospital of Wuhan University of Science and Technology from January to May,2012.The bubbles in the inferior conjunctiva fornix were examined by slit lamp microscope,and the break-up time (BUT) and Schirmer Ⅰ test (S Ⅰ t) were performed.The differences of BUT and S Ⅰ t between the two groups were compared using independent sample t test,and abnormality rate of examination indexes was statistical analyzed by CHI-Square test using a SPSS 11.5 software.Written informed consent was obtained prior to the clinical survey.Results In the 64 eyes of the bubbles group,incidence of dry eye was 75.00％,and the incidence of both BUT＜5 seconds and S Ⅰ t＜5 mm/5 minutes was 46.88％ ;while the incidence of BUT＜5 seconds or S Ⅰ t＜5 mm/5 minutes was 53.13％ and 57.81％,respectively.In 64 eyes without bubbles,incidence of dry eye was 31.25％,the incidence of both BUT＜5 seconds and S Ⅰ t＜5 mm/5 minutes was 18.75％,that of BUT＜5 seconds or S Ⅰ t＜5 mm/5 minutes was 21.88％ and 20.31％,respectively.The incidences of dry eye,both BUT＜5 seconds and S Ⅰ t＜5 mm/5 minutes,BUT ＜5 seconds,S Ⅰ t＜5 mm/5 minutes were significantly higher in the bubbles group than those of the without bubbles group (all at P=0.00).In the 68 eyes determined as dry eyes,48 eyes (48/68) were in the bubbles group and 20eyes (20/68) were in the without bubbles group,showing a significant difference between the two groups (x2 =24.60,P＜0.01).The incidences of both BUT＜5 seconds,S Ⅰ t＜5 mm/5 minutes were not significantly different between the two groups (x2 =0.01,P=0.95;x2 =1.06,P=0.30).Conclusions The bubbles in the inferior conjunctiva fornix is highly correlated with dry eye.

Objective To compare the effect of tension-free vaginal tape (TVT) and vaginal reconstructive surgery (VR) on women with severe genital prolapse and stress urinary incontinence.Methods 43 patients with stage I or II vaginal anterior defect and stress urinary incontinence were assigned to TVT group(21 patients) and VR group (22 patients) . Results Maximum quantity of urine, pressure of detrusor at maximum quantity of urine, and abdominal leakage point pressure occured significantly in TVT group after operation(P<0.05). Postoperative satisfaction rate were higher in TVT group(P<0.05). Conclusion TVT is more effective to improve the quality of life in women with stress incontinence.

Based on fundamental theory, literatures of TCM and clinical practice, we have found that there are some errors in the theory of stroke. We put forward several views on it: Firstly, the key reason of stroke is the hidden pathogenic factor which is phlegm and stasis, but not wind and fire. Secondly, the production of wind is due to the liver-blood injury caused by phlegm and stasis; the production of f ire is due to whether the liver-blood injury caused by phlegm and stasis or the f ire stagnated by phlegm and stasis in pericardium. Thirdly, the disease location of stroke is in the level of spirit, not in channels and collaterals. Liver soul injury leads to paralysis and aphemia. Lung soul injury leads to numbness. Kidney will injury leads to sensory aphasia. Pericardium invaded by phlegm and stasis, mind disorder will exists. Fourthly, spirit injury is a def icient syndrome, and supplementing blood and qi is the key of treatment, and expelling phlegm and stasis, balancing yin and yang are also needed. The main treatment principles of liver soul injury, lung soul injury, kidney will injury and pericardium injury are tonifying blood, cultivating qi, replenishing essence and nourishing both qi and blood respectively.

Objective To evaluate the efficacy of pneumocystoscopy for congenital malformation of the vesicoureteral junction. Methods A total of 18 children (male 11 and female 7, aged from 3 months to 7 years with a mean of 3.6 years) with congenital malformation of the vesicoureteral junction (22 ureters) were enrolled in this study. Among the patients, 9 had vesicoureteral reflux (4 of them had bilateral reflux), 2 had bladder diverticulum complicated with urethral stenosis, and 7 had urethral stenosis and ipsilateral hydronephrosis. After the bladder was insufflated with CO2 through a Foley catheter (16 mm Hg), three trocars were inserted into the bladder, and the bladder was fixed on the abdominal wall using silk thread. By pneumocystoscopy, the Cohen procedure was done through the trocars. A Foley catheter was indwelled at the end of the procedure. Results The procedure was completed in all but one patient, who was converted to open surgery because the contraction of the urethra. The mean operation time was 130 min (110 to 145 min) for unilateral cases (13), and 242 min (225 to 250 min) for bilateral cases. The patients were discharged form hospital 9 to 12 days after the operation, and were followed up fro 6 months to 5 years with a mean of 3.8 years. During this period, MUC showed no ureteral reflux. One of the cases developed mild infection of the urethra, and was cured by circumcision. Conclusion Pneumocystoscopy is effective for congenital malformation of the vesicoureteral junction.

Objective To explore the variation of the main chemical constituents of Herb Epimedii in decocting Herb Epimedii and Radix Astragali separately and compatibly. Methods Herb Epimedii combined with Radix Astragali were decocted with water in which the proportion of them were 1∶0, 2∶1, 1∶1, 1∶2 and 0∶1, respectively. RP-HPLC was used to compare the content of icariin and the fingerprints in separate and compatible decoction. Results Afeter combination, the number of chromatographic peaks were added and no new peaks were detected. The contents of some chemical constituents such as icariin in Herb Epimedii were increased, especially in the compatible decoction at the proportion was 1∶1. Some constituents were not changed obviously. Conclusion Herb Epimedii decocted together with Radix Astragali especially at a ratio of 1∶1 can increase the solubility of the chemical constituents in Herb Epimedii. This provides a scientific basis for more effective use of the compatible decoction of the two herbs.

AlM: To evaluate the clinical efficacy of canalicular intubation combined with external dacryocystorhinostomy ( ext-DCR ) for treatment of chronic dacryocystitis and upper lacrimal duct stenosis.
METHODS:Thirty-three patients (33 eyes) with chronic dacryocystitis and upper lacrimal duct stenosis who underwent canalicular intubation combined ext-DCR were retrospective analyzed. The silicon tube was indwelt for 6mo. All cases were re-examined 1wk;1, 3, 6, 9mo post-operation, flow of tears, pus excretion and lacrimal duct clearance were observed.
RESULTS: Clear lacrimal duct ratio was 100% in all cases during 1wk~6mo post-operation; Silicon tube was removed 6mo post-operation, 3mo after tube removal, rechecking reported 32 cases with clear lacrimal duct (97%) and 1 case with resistant duct (3%). Two cases ( 6%) with minor lacerations, no other complications were observed.
CONCLUSlON: Canalicular intubation combined ext-DCR is an effective treatment for chronic dacryocystitis and upper lacrimal duct stenosis.

AIM: To compare the effect of treating cataract by sodium hyaluronate injection and lens - loop nucleus extraction of small incision cataract excision and explore more suitable method to promote the use of surgery in primary hospital.
METHODS: All 146 cataract patients ( 166 eyes ) were allocated to two groups in random: the control group 78 patients ( 84 eyes ) received conventional lens loop for extracapsular cataract extraction;the experiment group 68 patients (82 eyes) underwent nucleus extraction in small incision with sodium hyaluronate injection for extracapsular cataract extraction. Postoperative visual acuity and intraoperative and postoperative complications were compared between two groups.
RESULTS: Incidence of posterior capsule rupture difference was statistically significant (P<0. 05) in small incision nucleus extraction with sodium hyaluronate injection compared with conventional lens loop for extracapsular cataract extraction. And there was no significant difference ( P> 0. 05 ) in postoperative visual acuity, astigmatism degree and postoperative complications compared with those of pre-operation.
CONCLUSION: Compared with the lens loop nucleus extraction, sodium hyaluronate injection for extracapsular cataract extraction can effectively protect the posterior lens capsule and can be promoted in small incision cataract surgery.
