AIM: To determine the effect of phacoemulsification and intraocular lens (IOL) implantation for angle closure glaucoma previously treated by laser iridotomy.METHODS: Thirty-nine patients(39 eyes )with angle closure glaucoma previously treated by laser iridotomy and cataract were divided into two groups according need for anti-glaucoma medications for controlling intraocular pressure (IOP) or not. All the patients underwent phacoemulsification and foldable IOL implantation and were followed up 3 months postoperatively.RESULTS: The best-corrected visual acuity(BCVA) of both groups improved significantly (P<0.05). The post-operative IOP of group I at 3 months was 15.72±3.02mmHg,and that of group Ⅱwas 16.30±3.81mmHg. The IOP of both group decreased significantly(P<0.05). The central anterior chamber depth of group I was deepened from 1.64±0.45mm preoperatively to 3.21±0.41mm at 3 months postoperatively,group Ⅱ was deepened from 1.92±0.52mm preoperatively to 3.18±0.39mm at 3 months postoperatively. The postoperative central anterior chamber depth of both groups increased significantly(P<0.05).Anterior chamber angle was much wider postoperatively.CONCLUSION: Phacoemulsification and IOL implantation was effective for angle closure glaucoma previously treated by laser iridotomy,and can improve visual acuity and completely relieve the pupillary block of angle closure glaucoma.

Results The IOP was significantly decreased 1 week,1 month,3 months and 6 months after SLT compared with that before treatment(P21 mmHg using two anti-glaucoma drugs,respectively. Conclusion SLT is a safe and effective method for IOP control in early CPACG after treatment with laser peripheral iridoplasty and laser iridectomy.

Objective To evaluate the therapeutic effects of needling revision with mitomycin C(MMC) subconjuctival injection on early failed filtering blebs after trabeculectomy for glaucoma. Methods Needling revision with MMC 0.2 mL(0.04 mg) subconjuctival injection was performed on 86 eyes of 76 patients with failed filtering blebs 2 to 6 weeks after trabeculectomy for glaucoma.An average of 1.88 times of treatment was performed.The intraocular pressure(IOP),blebs and side effects were observed,and follow-up was conducted for 6 months. Results Two to six weeks after trabeculectomy,there were 50 eyes with thickened and focalized blebs,32 eyes with encapsulated blebs and 4 eyes with no bleb.Six months after needling revision with MMC subconjuctival injection,blebs of 61 eyes turned into functional ones.The blebs were thinned and multicysted in 24 eyes,diffused and elevated in 37 eyes,thickened and focalized in 6 eyes,encapsulated in 13 eyes and disappeared in 6 eyes.Three months after treatment,the mean IOP was(15.2?6.1) mmHg,and there were 57 eyes with IOP

Objective To investigate the expression and the effects of X-chromosome linked inhibi- tor of apoptosis (XIAP) associated factor 1 (XAF1) on apoptosis and cell proliferation in SMMC7721 hepatocellur carcinoma (HCC) cell line.Methods The expression of XAF1 mRNA and protein in hu- man SMMC7721 cell line were detected by semi-quantitative,RT-PCR and Western blot.Plasmid con- structs expressing sense and antisense XAF1 were generated and transfected into SMMC7721 cell line to establish stable transfectants.Cell proliferation and apoptosis were detected by MTT,flow cytometry and TUNEL.Results XAF1 mRNA and protein were detectable in SMMC7721 cell line but lower than that in normal liver cell.Stable expression of XAF1 significantly inhibited cell proliferation and increased spontaneous apoptosis in SMMC7721 cell (P＜0.05).Over-expression of XAF1 in stable transfactants increased the sensitivity of SMMC7721 cell to chemotherapeutic drugs such as 5-fluorouracial and hydroxycamptothecin.Conclusions Over-expression of XAF1 induces apoptosis and inhibits SMMC7721 cell growth.XAF1 may be a promising candidate for HCC gene therapy.

[Objective]To investigate the value of degree centrality(DC),a novel resting-state fMRI parameter,in voxel-wise whole-brain functional networks analysis in primary insomnia(PI)after acupuncture therapy.[Methods]The resting state fMRI were performed in 29 PI patients and 22 age,education,and sex-matched normal healthy subjects. Analysis of DC map changes between the two patient groups and the control group were performed by two sample t test.(threshold at P<0.05).[Results]Compared with the control group,patients with PI showed significantly reduced DC value in middle temporal gyrus(MTG. R);hippocampus(HIP. B);parahippocampal gyrus(PHG. R);putamen(PUT. R);cuneus(CUN. L).[Conclusions]Changes of DC value occurred in some region of brain in the PI patient groups when compared with the control group. It was indicated that DC ,as a novel resting-state fMRI parameter in the voxel-wise whole-brain functional networks ,might be an appealing alternative approach for further study on pathologic and neuropsychological states of PI.

[Objective]To investigate the micro-structural alterations within whole brain white matter(WM) in cough syrup abuse addiction patients containing codeine,and to explore the correlation between aberrant WH and abuse time of cough medicine abuse patients.[Methods]Thirty cough syrup abuse addiction patients containing codeine and 30 controls participated in the study. Structural changes in FA and(mean diffusivity)MD were examined in cough syrup abuse addiction patients containing codeine which derived from DTI tractography. Pearson correlation analysis was performed to compare the mean FA value and duration of cough syrup abuse addiction in patients.[Results]Cough syrup abuse addiction patients containing codeine had lower FA value in bilateral anterior limb of internal capsule(ALIC)and higher MD in the bilateral hippocampus and insula,right anterior cingulate cortex(ACC)and superior temporal gyrus,compared to the controls. Cough syrup abuse addiction group also had positive correlation between mean FAvalues and duration of cough syrup abuse addiction in patients.[Conclusion]Micro-structural alterations within whole brain white matter(WM)are found in cough syrup abuse addiction patients containing codeine. This disturbance progresses as duration increases of cough syrup abuse addiction in patients.

Objective To investigate the clinicopathologic characteristics and prognosis of triple negative breast cancer patients. Methods A retrospective analysis was performed for 1042 primary breast cancer patients admitted in the First Affiliated Hospital of Nanjing Medical University from January 2003 to December 2009.All breast cancer patients were categorized into three subgroups by immunohistochemistry:ERBB2 +,HR +/ERBB2 - and triple negative. Results Of 1042 breast cancer patients recruited,183 patients were in triple negative group.The rate of larger tumors ( greater than 2 cm in diameter) and grade Ⅲ in triple negative patients was higher than that in ERBB2 + and HR +/ERBB2 - patients (P ＜0.01 ).The positive rate of p53 status in ERBB2 + patients was higher than that in triple negative and HR +/ERBB2- patients (P ＜ 0.01 ).No significant differences were observed in other clinical variables.In survival analysis,more bone metastases were observed in HR +/ERBB2 - patients than in ERBB2 + and triple negative patients (P =0.006).However,no significant difference was observed in visceral metastases among the subgroups.There were significantly different recurrence-free survivals (RFS) among the three subgroups throughout the follow-up period ( P =0.029),the 5-year RFS of ERBB2 + was 80.3％,which was the worst in three groups. Conclusions Triple negative patients had higher rate of larger tumors (greater than 2 cm in diameter) and grade Ⅲ than that in ERBB2 + and HR +/ERBB2 - patients,while its 5-year RFS was higher than ERBB2 + patients.

Objective To investigate symptom characteristics and their their prevalence in terminally ill patients with ovarian carcinoma.Methods A retrospective study was carried out based on clinical data of 98 terminally ill patients with ovarian carcinoma who died in our hospital during January 1995 to December 2004.Fifteen most common symptoms were analyzed with a focus on the followings:symptom incidence,survival time after symptom occurrence,regularity of symptom cluster,and common causes of death.Fifteen symptoms were:pain,cachexia,pleural effusion and ascites,dyspnea,fever,intestinal obstruction,renal failure,bone marrow depression,lung infection,hemorrhage,deep venous thrombosis (DVT),intestinal or pancreatic fistula,mycotic infection,jaundice and emergency conditions.Results (1)The most prevalent symptom was pleural effusion and ascites(63%),followed by pain(60%), cachexia(59%),dyspnea(52%)and intestinal obstruction(49 %).(2)The symptom which lasted longest survival time was mycotic infection(77 days),followed by intestinal or pancreatic fistula(75 days), intestinal obstruction(67 days),pain(60 days)and eachexia(60 days).Symptoms such as bone marrow depression,renal failure,dyspnea and emergency conditions were comparatively critical associated with shorter survival times(14,13,12,7 days,respectively).(3)Terminal symptoms occurred typically in clusters,with 4.9?1.5 symptoms per case.Of 98 cases,84 cases(86%)had 4 or more symptoms,with the median survival time of 63 days from the last day of anti-cancer therapy,and a slow death process.The remaining 14 cases(14%)with 3 or fewer symptoms survived only 25 days,of which 10 cases(71%)died of emergency diseases.The survival time for two groups was significantly different(P

Objective To evaluate the development of immature oocytes after freezing-thawing by conventional cryopreservation method for mature oocytes.Methods Immature oocytes were collected from stimulated ovaries of intracytoplasmic sperm injection(ICSI)cycles.Immature oocytes were in vitro matured directly or after slow freezing-fast thawing and immunostained for tubulin and chromatin and at last visualized by confocal microscopy.Results No statistical difference was found in maturity rate between freezing groups and the controls.There was a statistically significant increase in abnormalities of chromosome(23.7% vs. 50%)and spindle(28.9% vs.53.9%)in the GV freezing group compared with the GV control(P
