目的:观察玻璃体手术治疗糖尿病黄斑水肿(DME)术后1a的疗效。方法:对89例(116眼)糖尿病黄斑水肿患者行玻璃体手术,观察手术前、后患者的视力、黄斑水肿改善程度以及手术并发症的情况。随访时间为1a。结果:随诊1a,术后最佳矫正视力(0.428±0.387〔mean±SD〕)与术前最佳矫正视力(0.285±0.249)比较,差异有非常显著意义(P<0.0001);41只非增殖性糖尿病视网膜病变眼中,术后最佳矫正视力(0.450±0.410)与术前最佳矫正视力(0.291±0.201)比较,差异有显著意义(P=0.0171);75只增殖性糖尿病视网膜病变眼中,术后最佳矫正视力(0.416±0.376)与术前最佳矫正视力(0.282±0.272)比较,差异有非常显著意义(P<0.0001);糖尿病视网膜病变分期对最终视力并无影响。术后,74眼黄斑水肿吸收,占63.8%。随诊中,53眼最佳矫正视力提高2行或2行以上,占45.7%;39眼视力不变,占33.6%;24眼视力下降2行或2行以上,占20.7%。术中及术后并发症包括,医源性视网膜裂孔,玻璃体积血,新生血管性青光眼,黄斑中心凹硬性渗出,黄斑萎缩及黄斑上膜。这些并发症中造成最佳矫正视力下降2行或2行以上的原因是新生血管性青光眼(4眼),黄斑萎缩(10眼),硬性渗出(9眼)及黄斑上膜(1眼)。结论:玻璃体手术可以有效提高糖尿病黄斑水肿患者的视力及改善黄斑水肿,但此治疗有着严重的并发症,因而应仔细认真行术前术后检查,掌握手术技巧。

This study focused on measurement of the autothermal reforming of biogas over a Ni based monolithic catalyst. The effects of the steam/CH4 （S/C） ratio, O2/CH4 （O2/C） ratio and temperature were investigated. The CH4 conversions were higher under all examined temperatures than the equilibrium conversion calculated using the blank outlet temperature, because the catalyst layer was heated by the exothermic catalytic partial oxidation reaction. The CH 4conversion increased with increasing O2/C ratio. Moreover, the CH4 conversion was higher than the equilibrium conversion calculated using the blank outlet temperature for O2/C〉0.42 and reached about 100% at O2/C=0.55. However, the hydrogen concentration decreased for O2/C〉0.45 because hydrogen was combusted to steam in the presence of excess oxygen. On the other hand, the hydrogen and CO2 concentrations increased and the CO concentration decreased with increasing SIC ratio. As a result, it was found that the highest hydrogen concentrations and CH4 conversions were attained at the O2/C ratios of 0.45-0.55 and the SIC ratios of 1.5-2.5. Moreover, the H2/CO ratio could also be controlled in the range from about 2 to 3.5 to give at least 90% CH4 conversion, by regulating the O2/C or S/C ratios.

We discuss a problem on the third-order determinant, paying attention to the number of zero in the nine elements of the determinant. Solutions of E. A. Molnar’s problem are also obtained as a result.

By studying the county-level census data of 1990 and 2000, we analyzed the spatial and temporal changes in the floating population in China between 1990 and 2000. The results of the analysis revealed the following characteris- tics. First, the spatial distribution of the migrants (referred to as 'floaters' in this paper) became increasingly concentrated in the cities during the 1990s. Second, the number of floaters increased rapidly during this period, and the area in which the floaters settled expanded quickly into four population explosion belts: the coast, the Changjiang River Delta, the Beijing-Guangzhou Railway and national border belts. Third, the number of inter-province floaters increased rapidly and exceeded that of intra-province floaters in the 1990s. In addition, to obtain a quantitative relationship between the number of floaters and 10 socio-economic variables by using statistical methods and also to find the chiefly important pulling factors of the migration destination, the authors selected approximately 100 cities with the largest population of floaters. Consequently, we found that four factors-GDP, passenger trips per 10,000 persons, per capita GDP and foreign direct investment-could provide an explanation for 83.7% of the number of floaters in 2000. The GDP showed the highest correlation with the number of floaters, suggesting that a highly developed economy is the most important factor that attracts floaters. Furthermore, a fairly close relationship between the number of floaters and the GDP was also found in 2000 for all the counties.

AIM:To evaluate the role and outcome of pericardiocentesis with intrapericardial cisplatin instillation for malignant pericardial effusion resulting from esophageal cancer. METHODS:We retrospectively studied 7 patients who underwent pericardiocentesis with intrapericardial cisplatin instillation for malignant pericardial effusion resulting from esophageal *** pericardiocentesis,we performed catheterization of the pericardial space under ultrasonogram *** etiology of the pericardial fluid was confirmed by cytological ***,cisplatin(10 mg in 20 mL normal saline) was instilled into the pericardial space. RESULTS:The mean total volume of the aspirated effusion fluid was 782±264 mL(range,400-1200 mL) . The drainage catheter was successfully removed in all patients,and the mean duration of pericardial drainagewas 7.7±2.7 d(range,5-13 d) .No fluid reaccumulation was *** survival time was 120±71 d(range,68-268 d) . CONCLUSION:Pericardiocentesis along with catheter drainage appears to be a safe and effective for pericardial malignant effusion and tamponade,and cisplatin instillation prevents recurrence.

AIM: To study the relationship between platelet count-to-spleen diameter ratio and post-gastrectomy esopha-geal varices (EVs) development in patients without liver cirrhosis or hepatitis. METHODS: We retrospectively studied 92 patients who underwent gastrectomy. They were divided into 2 groups on the basis of the surgical treatment: the distal gastrectomy (DG) group and total gastrectomy (TG) group. The incidence of EVs was determined and postoperative platelet counts, spleen diameters, and platelet count-to-spleen diameter ratios were com-pared between the 2 groups. RESULTS: EVs were not detected during the first 6 mo after surgery in either group; however, at 12 mo after surgery, EVs were detected in 2 patients (3%) in the DG group and in 1 patient (3.6%) in the TG group; their mean platelet count-to-spleen diameter ratio was 2628 ± 409, and 2604 ± 360, ***: Endoscopy should be performed to detect EVs when the platelet count-to-spleen diameter ratio is < 2600.

AIM:To evaluate the efficacy of endoscopic examination of blood flow and edema in the remnant ***:We retrospectively studied 15 patients who underwent massive bowel resection with enterostomy for superior mesenteric arterial occlusion (SMAO); the patients were divided into a delayed closure group (D group) and an early closure group (E group).RESULTS:The mean duration from initial operation to enterostomy closure was significantly shorter in the E group (18.3 ± 2.1 d) than in the D group (34.3 ± 5.9 d) (P < 0.0001). The duration of hospitalization after surgery was significantly shorter in the E group (33 ± 2.2 d) than in the D group (51 ± 8.9 d) (P < 0.0002).CONCLUSION:Endoscopic examination of blood flow and edema in the remnant bowel is useful to assess the feasibility of early closure of enterostomy in SMAO cases.
