AlM: To evaluate the clinical efficacy and safety of capsular tension ring ( CTR) combined with iris hooks in eyes with large traumatic zonular dialysis or weakness that underwent micro -incision coaxial phacoemulsification with posterior chamber ( PC ) intraocular lens ( lOL) implantation.METHODS: This prospective study was carried on 21 patients ( 21 eyes ) with traumatic cataract and traumaticzonular dialysis (<180 degrees determined pre-or intra-operatively ) in our hospital from January 2011 to September 2014. After CCC, 1-4 iris hooks might be used probably and a in-the-bag CTR was inserted in order to maintain or re-establish an extended capsular diaphragm before or at any time during cataract removal. Then micro-incision coaxial phacoemulsification with foldable acrylic PC lOL implantation was performed. Zonular dialysis range, posterior capsule rupture, vitreous loss, pupil size, best corrected visual acuity ( BCVA ) , intraocular pressure ( lOP ) in the pre- and post-operative periods and postoperative lOL decentration were observed after operation.RESULTS: The mean follow-up period was 3 ~12mo. No serious postoperative complication was found. BCVA in our cases: <0. 3 in 1 eye, 0. 4~0. 7 in 15 eyes ,>0. 8 in 5 eyes. lOPs were in normal range too. The lOLs in 20 eyes remained the required position to the final follow- up examination except one eye in which the PC lOL was dislocated into vitreous cavity due to a postoperative spontaneity PCR, and in which vitrectomy and lOL suture fixation was performed.CONCLUSlON: ln cases of cataract associated with traumatic zonular dialysis (<180.) , by setting the rational parameters of phacoemulsification, the CTR and iris hooks are found to be efficient in preventing lOL decentration and reducing operation complication. ln our cases, the CTR combined with iris hooks is relatively safe application.

Objective To investigate the safety and efficacy of retroperitoneal laparoscopy for adrenal tumor and report the experience with this procedure for adrenal surgery.Methods From June 2003 to March 2007,we performed 24 laparoscopic tumorectomy via the retroperitoneal approach.Results All procedures were successful. The average operative time was 1.7 hours(ranging from 1 to 3.5 hours).All patients had no need of transfusion and no complication.All patients recovered.The average hospital stay was 4.5 days(ranging from 3 to 8 days).Patholog- ic diagnosis:10 cases of nonfunctional adenoma,6 cases of primary aldosteronism,4 cases of adrenal cyst,2 cases of pheochromocytoma,2 cases of Cushing's adenoma.Conclusions Retroperitoneal laparoscopic surgery for adrenal oc- cupying lesion had such advantages as minimal invasive,safe and effective,early recovery and shorter stay in hospital. It should be the flint choice of treatment for adrenal occupying lesion.

Objective To investigate the expression of vascular endothelial growth factor(VEGF)in synovium of rats with adjuvant arthritis and the relationship between the histopathologic score and the expression of VEGF.Methods Adjuvant arthritis was established in Wistar rats by inoculating complete Freund's adjuvant(CFA). We calculated the arthropathologic score and the expression of VEGF mRNA and protein at different stages after CFA inoculation.Results In model group the arthropathologic score and expression of VEGF protein in synovium increased significantly all the time (P

Objective To investigate the effect of green light laser in complex posterior urethral stricture after surgical treatment of benign prostatic hyperplasia (BPH).Methods Green light laser was applied in treating 20 cases of complex iatrogenic posterior urethral stricture.Of these cases,12 had false passages,5 had more than 2 strictures and 5 had concurrently urethratresia.The scar tissues were transure- thrally vaporized and resected.The in-dwelling urethral catheter time was 1-2 months after operation. Results All the patients were initially cured without serious complications.The mean operative time was 39 rain (range,30-65 min).During the follow-up of 2-10 months,1 case had mild incontinence:another case (Q_(max)＜9ml/s 2 weeks after surgery) got satisfactory results(Q_(max)＞15ml/s)after the scheduled urethral dilatation.The other 18 cases were treated successfully and voided fluently with postoperative Q_(max)＞15ml/s in all.Conclusions It is suggested that transurethral green light laser procedure is not only safe and ef- fective,but also simple and minimally iuvasive for complex posterior urethral stricture following surgical treat- ment of BPH.

Objective To investigate the effect of the continuous care support intervention on breast cancer patients with radical mastectomy.Methods Totals of 107 patients undergoing elective radical mastectomy were randomly divided into intervention group ( n =54 ) and control group ( n =53 ).Both of two groups of patients were treated on the basis of conventional care according to the doctors' advice before and after surgery.The intervention group received the continuous individual nursing intervention model,included preoperative interactive support intervention,postoperative pain assessment support intervention and rehabilitation support intervention after discharge. Intervention effects of two groups were observed and compared. Results The anxiety,positive response and negative response of two groups patients were no significant differences before intervention (P＞0.05).After intervention,the scores of anxiety,positive response and negative response in intervention group respectively were (35.28 ± 5.43 ),(39.82 ±4.03 ) and (25.61 ± 5.12),and that of control group were (42.73 ± 6.72),(33.15 ± 5.62) and (31.75 ± 6.38),and the difference was statistically significant ( t =6.313,7.065,5.495,respectively; P ＜ 0.01 ).The duration of postoperative different period pain score,first off the bed time,sleep time,upper extremity swelling and hospitalization days were statistically significant between two groups (P ＜0.01 ).And the postoperative recovery state of upper limb function after six months,and life quality score after one year in intervention group were significantly better than that of control group ( P＜0.01 ).Conclusions Continuous individualized specialized nursing intervention support model can promote physical function in patients with early recovery and improve quality of the prognosis life and the treatment outcome.

ObjectiveTo investigate the value of 99Tcm labeled survivin mRNA antisense peptide nucleic acid (PNA) as an imaging agent in the specific diagnosis for carcinoma.MethodsSurvivin mRNA antisense PNA was labeled directly with 99Tcm by the ligand-exchange method.Twenty nude mice with lung carcinoma A549 xenografts were randomly divided into 4 groups.Three groups were used for biodistribution study and one group was used for imaging study.Other twenty mice infected by staphylococcus aureus underwent the same procedure.The biodistribution and imaging of 99Tcm-survivin mRNA antisense PNA was studied at 1,2 and 4 h respectively after the intravenous injection in nude mice bearing lung carcinoma A549 xenografts or inflammation models.SPSS 13.0 was used in the study and all data were analyzed by t test.ResultsBiodistribution results showed that the highest radioactivity was found in the liver,and then in the kidney.Four hours after the administration of the imaging agent,the radioactivity ratios of target-tonon target (T/NT,tumor or inflamumatory lesions to the contralateral regions) in tumor model group were significantly higher than those in inflammation model group ( 3.69 ± 1.13 vs 2.03 ± 0.47,t =3.01,P =0.02 ).Tumors were clearly visible in the tumor model groups at 0.5 h and still clearly seen at 4 h after the injection of antisense PNA.On the contrary,inflammatory lesions could not be seen clearly.Conclusion 99Tcm labeled survivin mRNA antisense PNA can be used to distinguish tumor from inflammation and it may provide a new feasible method for specific tumor diagnosis.

OBJECTIVETo evaluate and compare the effect of naso-intestinal tube decompression and octreotide in conservative management of early post-operative inflammatory ileus (EPII).

METHODSFrom March 2005 to January 2009, forty-five patients diagnosed with EPII, who failed to improve with conventional conservative management including nasogastric tube decompression, were enrolled in this study. All patients were prospectively nonrandomized into naso-intestinal tube group (n = 23) or Octreotide group (n = 22). The outcomes were compared between nasogastric tube, naso-intestinal tube and Octreotide groups.

RESULTSAll the forty-five patients with EPII refractory to conservative management with nasogastric decompression were treated successfully with the naso-intestinal tube decompression or octreotide in 3-12 days. Compared with the Octreotide group, the first passage of flatus was earlier [(4.7 +/- 1.9) d vs (6.7 +/- 1.6) d] and abdominal circumference recovered faster [(90.4 +/- 2.0)% vs (95.1 +/- 1.3)%] in the naso-intestinal tube group (P < 0.05). But the volume of cumulative and daily gastrointestinal decompression were more in naso-intestinal tube group than those in Octreotide group [(4037 +/- 1155) ml vs (3316 +/- 1038) ml; (890 +/- 181) ml vs (492 +/- 83) ml; P < 0.05].

CONCLUSIONSPatients with EPII could be safely and effectively managed by naso-intestinal tube decompression or octreotide. It is possible for those patients to avoid second laparotomy. Naso-intestinal tube decompression and octreotide are associated with faster recovery and less fluid loss respectively.
