AIM: To analyze and summarize the effect of glaucoma trabeculectomy in the department of ophthalmology in basic hospital.
METHODS: Postoperative intraocular pressure ( IOP ) , filtering bleb and complications of 316 cases (405 eyes) of patients with glaucoma after trabeculectomy were analyzed.
RESULTS: After follow- up 12mo, 76. 5% IOP was controlled in normal level. 42. 5% was filtration bleb typeⅠ, 33. 1% typeII, 14. 6% in typeⅢand 9. 9% in typeⅣ. Intraoperative complication rate was 2. 5%, that was 31.4% at postoperative early stage ( before discharge ) , and 6. 7% at postoperative long - term ( 6mo after discharge) .
CONCLUSION:Trabeculectomy for glaucoma can better solve the problem of high IOP. It is more mature in primary hospitals, but there are still a variety of intraoperative and postoperative complications.

Medicinal properties are specific attributes of traditional Chinese medicines(TCM). The medicinal property theory is an important principle for the compatibility of traditional Chinese medicines. In this paper, medicinal properties, flavors and meridian tropism were combined to represent TCM medicinal properties; and multiple medicinal properties were further combined into medicinal property combination modes. TCMs and medicinal property combination modes were divided according to their efficacies, which were regarded as the concept of inductive logic programming and finally got medicinal property combination and compatibility rules with different efficacies. These medicinal property combination and compatibility rules were used to form the theoretical model through the entity grammar system, realize the automatic reasoning process from the medicinal property combination and compatibility to the efficacies, verify the reasoning result and analyze their rationality and limitations, in order to provide new ideas for revealing the relations between the TCM compatibility rules and efficacies.

objective To investigate the ability of insulin sensitivity index HOMA2-%S and secretion function index HOMA2-%B calculated by HOMA2,the new homeostasis model assessment,in clinical application. Methods Eighty female volunteers with polycystic ovary syndrome in Chongqing area [50 subjects with normal glucose tolerance(NGT group)and 30 subjects with impaired glucose regulation(IGR group)]were involved in this study.Thev underwent a 75 g oral glucose tolerance test(OGTF)and the Botnia clamp test. From the data of faming blood samples in OGTF,insulin sensitivity index HOMAI-ISI,secretion function index HOMAl-β and disposal index DI-HOMA1 were calculated by the old homeostasis model assessment(HOMA I),meanwhile insulin sensitivity index HOMA2-%S,secretion function index HOMA2-%B and disposal index(DI-HOMA2) were caleulated by the new homeostasis model assessment (HOMA2).Correlation coefficients between insulin sensitivity index and GIR (the glucose infusion rate at steady state of Botnia clamp test),and between insulin secretion function index and AIR(the acute insulin response in Botnia clamp test),were studied.Results The Pearson's linear correlation coefficient between HOMA2-%S and GIR(r=0.503),HOMA1-ISI and HOMA2-%S (r= 0.990).HOMA2-%B and AIR(r=0.382),HOMA1-B and HOMA2-%B(r=0.976) were all statistically significant(a11 P<0.01).The glucose disposal indexes calculated from the HOMA2 and HOMA1 of 1GR group were significantly lower than those from the NGT group(t=2.825,P<0.Ol;t=2.222,P<0.05). Conclusion The HOMA2 is a better model in evaluating the insulin sensitivity and secretion function and is recommended to be widely used in clinical evaluation.

Objective To investigate the CT spectral imaging features of pancreatic serous oligocystic adenoma and mucinous cystic neoplasms and to assess the value of spectral CT in differentiating between pancreatic serous oligocystic adenoma and mucinous cystic neoplasms. Methods From Feb.2010 to Dec. 2010, 27 patients with cystic neoplasms of the pancreas (group one with 15 serous oligocystic adenomas and group two with 12 mucinous cystic neoplasms) underwent dual-phase CT spectral imaging followed by surgery. Quantitative values (age, tumor size, CT value change as function of photon energy,effective-Z, iodine-water concentration, and calcium-water concentration) were compared with independent samples t test and Mann-Whitney test and non-quantitative parameters (gender, symptom, and tumor location) were compared with Chi-square test (Fisher exact). The parameters with significant differences between two groups were analyzed further and the performance of multiple parameters for joint differential diagnosis was evaluated with discriminant analysis. Results Compared to patients with mucinous cystic neoplasms, patients with serous oligocystic adenoma had younger age, lower frequency of being symptomatic and smaller tumor size. The CT values on 40 keV to 60 keV( with 10 keV increment) in late arterial phase [(36±13)HU vs. (62±23)HU, (26 ±8)HU vs. (40±15)HU, and (19±6)HU vs. (27±10)HU respectively] and 40 keV to 50 keV (with 10 keV increment) in portal venous phase [ (43 ± 14 )HU vs.(61 ±25)HU and (30 -10)HU vs. (40 ± 16)HU respectively], effective-Z (late arterial phase 7.80 ± 0. 16 vs. 8.05 ± 0. 21, and portal venous phase 7. 87 ± 0. 15 vs 8.02 ± 0. 22 ), concentration of calcium (water) [late arterial phase (5 ±3) g/L vs. (11 ±4) g/L, t= -3.836, P=0.001 and portal venous phase (7 ± 3 ) g/L vs. ( 10 ± 5 ) g/L, t = - 2.071, P = 0. 049 ] and iodine (water) [ late arterial phase (0.38 ±0.24) g/L vs. (0.78 ±0.32) g/L, t = -3.755, P=0.001 and portal venous phase (0.48 ± 0. 24) g/L vs. (0. 72 ± 0. 34 ) g/L, t = - 2. 161, P = 0. 041 ] were lower in serous oligocystic adenoma than those in mucinous cystic neoplasms. In discriminant analysis, multiple parameters [ age, symptom,tumor size, CT values on 40 keV to 50 keV, effective-Z, concentration of iodine (water) in late arterial phase and concentration of calcium (water) in portal venous phase] showed high accuracy (100%, 27/27 )of joint diagnosis between serous oligocystic adenoma (100%, 15/15 ) and mucinous cystic neoplasms (100%, 12/12). Conclusions The serous oligocystic adenoma and mucinous cystic neoplasms had distinct characteristic findings on CT spectral imaging. CT spectral imaging is highly accurate in the differential diagnosis between serous oligocystic adenoma and mucinous cystic neoplasms.
