AIM: To investigate the effect and safety of laser peripheral iridoplasty combined with iridectomy in the unmanageable acute angle - closure glaucoma by medication.
METHODS:Totally 19 cases (21 eyes) with acute angle-closure glaucoma, including 15 cases ( 17 eyes ) with primary glaucoma and 4 cases (4 eyes) with intumescent cataract - induced glaucoma, were recruited into the study. The intraocular pressure ( IOP ) of all cases were still >21mmHg after 24h drug treatment, and then were treated by laser peripheral iridoplasty combined with iridectomy. The visual accurity, IOP, cornea, peripheral anterior chamber depth, anterior chamber angle and complications were observed at 24h after the surgery.
RESULTS:The mean IOP of all cases was reduced from 53. 09±11. 01mmHg before the surgery to 14. 98±4. 21mmHg at 24h after the treatment, with significant statistical difference ( P< 0. 01 ). The visual acurity of all cases increased in different degrees from handle move to 0. 3 to 0-1-1. 0 at 24h after the treatment. In all cases, cornea edema reduced or cleared up, peripheral anterior chamber depth increased, and anterior chamber angle reopened in different degrees. Complications included iris hemorrhage in 11 eyes (52. 4%), mild iritis in 21 eyes (100%). No cornea burn was encountered.
CONCLUSION: Laser peripheral iridoplasty combined with iridectomy is an effective and safe method for the treatment of the unmanageable acute angle - closure glaucoma by medication.

Exposure to traffic-related air pollutants(TRAP)has been implicated in airway allergic diseases.Recent findings include epidemiologic and mechanistic studies that shed new light on the impact of TRAP on allergic rhinitis(AR)and the biology underlying this impact.These studies have found that oxidative stress induced by TRAP could affect the axis of epithelial cell-dendritic cell-T cell towards a T-helper 2 immune response,which is the major mechanism between TRAP and AR.Further,epigenetics and microRNA might be involved in this process.Our review will summarize the most recent findings in each of these areas.

Objective To observe the therapeutic effect of phloroglucinol combined with diazepam in prolonged or protracted active phase of first stage of labor,and the outcome of perinatal phase.Methods Two hundred vaginal delivery primipara with prolonged or protracted active phase after dilatation of cervix 2-3 cm were selected.The patients were divided into 2 groups by random digits table method with 100 cases each,the patients in observation group were given phloroglucinol 80 mg and diazepam 10 mg,and the patients in control group were given diazepam 10 mg.The cervical dilatation,the degree soft hardness and edema of cervix,time of active phase,time of second stage of labor,mode of delivery,vaginal bleeding in 2 h postpartum and outcome of perinatal phase in the 2 groups were observed.Results In observation group,the cervical dilatation rate was (2.31 ± 0.27) cm/h,the time of active phase was (187.27 ± 33.22) min.In control group,the cervical dilatation rate was (1.82 ±0.48) cm/h,the time of active phase was (251.32 ± 45.33) min,there were statistical differences between 2 groups (P ＜ 0.05).The rate of uterineincision delivery in observation group was significantly lower than that in control group [18.0％(18/100) vs.32.0％ (32/100)],there was statistical difference (P ＜ 0.05).There were no statistical differences in time of second stage of labor,vaginal bleeding in 2 h postpartum,rate of neonatal asphyxia between 2 groups (P ＞0.05).Conclusion The effect of phloroglucinol combined with diazepam in prolonged or protracted active phase is remarkable,it can promote the progress of labor,speed up delivery progress,improve the rate of vaginal delivery and decrease the rate of uterine-incision delivery,and no adverse effects on the outcome of perinatal phase,it is worth popularizing.

Objective To investigate the application of homemade stapler in anus-retained operation on low and super-low colon or rectal cancer.Methods From August 1991 to August 2006,this technique was used in 333 patients with low colon or rectal cancer,among which 96 patients were right hemicolon excision,ileum colon anastomosis,colon sigmoideum excision,colon descendens rectum anastomosis and 183 patients were rectum pro-excision,low pro-excision,54 patients were low pro-excision,super low anastomosis.The other traditional operations(59 patients manipulation anastomosis) were used in 166 patients.Results Fourteen patients had anastomotic fistula(one rectovaginal fistula) in group1 and two in group2.Two patients had pro-sacral bone bleeding,and one dead.Conclusion The stapling device was a safe and feasible choice in anus-saving operation of low rectal cancer.

Graves' ophthalmopathy (GO) is an autoimmune disorder representing the commonest and most important extrathyroidal manifestation of Graves' disease.GO can be a debilitating component of the disease,resulting in impaired quality of life.Although therapeutic methods appear to be widespread,the optimal treatment remains challenging.This article reviewes recent studies on therapy pattern and evidence-based medicine,to provide practical information for managing patients with GO.

Exendin-4,a peptide analogue of glucagon-like peptide-1(GLP-1),is presently in clinical trials as a therapy for type 2 diabetes mellitus.Exendin-4 selectively acts on GLP-1 receptors,which are coupled to the cAMP nucleotide second messenger pathway to enhance the survival and plasticity of neurons in the brain.Exendin-4 has potent effects on homeostasis of Ca2+,on multiple targets to block apoptotic signaling pathways,and on neuronal proliferation and differentiation.It has also been demonstrated to possess properties against oxidative stress and excitotoxicity.In this review the functions of exendin-4 on central nerve system and the potentia therapeutic effects on neurodegenerative diseases will be involved.

Objective To study the association of apolipoprotein ( Apo) E gene polymorphism with difference in biochemical metabolism of diabetic nephropathy of Hui and Han populations. Methods ApoE genotype was determined by PCR-RFLP in diabetic patients with or without diabetic nephropathy (DN) and normal peoples in Hui and Han peoples, the related biochemical parameters were simultaneously detected. Results (1) Huis had 3 genotypes, i. e. E2/E3, E3/E3 and E3/E4, and their frequencies were 0. 043, 0. 894 and 0. 064, respectively. Hans had 5 genetypes, i. e. E2/E2, E2/E3 , E2/E4, E3/E3 and E3/E4, and their frequencies were 0.075,0.060, 0.164, 0.642 and 0.060, respectively. The frequencies of 3 alleles, E2, E3 and E4, in Huis and Hans were 0.021, 0.947, 0.032 and 0.187, 0. 702, 0.112, respectively. The results showed that difference in frequencies of genotypes and alleles of Huis and Hans was very significant (both P

AIM To observe the change of Ca 2+ /calmodulin dependent protein kinaseⅡ (CaMKⅡ) signal pathway in opioids dependent NG108-15 cells and the relationships between Ca 2+ /calmodulin dependent protein kinaseⅡ (CaMKⅡ) signal pathway and cAMP accumulation. METHODS NG108-15 cells were used as an in vitro model system. Competitive protein binding assay and radioimmunoassay were used to examine the intracellular cAMP accumulation. Calmodulin activity was assayed by PDE method. CaMKⅡ activity was assayed by ?- 32 P incorporation of syntide-2. mRNA expression of mDOR was measured by RT-PCR. RESULTS DPDPE long-term treatment also increased cAMP accumulation, and resulted in opioids dependence in NG108-15 cells; DPDPE long-term treatment increased calmodulin activity and CaMKⅡ activity in NG108-15 cells. Specific calmodulin antagonist W-7 was found to inhibit significantly the elevation of calmodulin and CaMKⅡ activity which resulted from DPDPE long-term treatment, and CaMKⅡ inhibitor KN-62 also inhibited elevation of CaMKⅡ activity by DPDPE long-term treatment. DPDPE long-term treatment increased cAMP accumulation, when W-7 or KN-62 was added at the same time, cAMP accumulation decreased. When naloxone was added to NG108-15 cells which were long-term treated by DPDPE, calmodulin and CaMKⅡactivity increased more. mRNA level of mDOR did not change significantly in opioids dependent NG108-15 cells. CONCLUSION Ca 2+ /CaMKⅡ signal pathway was involved in the mechanisms of opioids dependence through regulating cAMP level when DPDPE is long-term administered to NG108-15 cells.
