Diabetic cataract is an metabolic-type cataract. Its pathogenesis mechanism is not completely clear. Researches demonstrated that glycosylation plays an increasingly important role in the formation of diabetic cataract,and increased blood glucose level promote the pathogenesis and progression of diabetic disease by accelerate the glycosylation response. Therefore, more researches on advanced glycation end products(AGEs) and its inhibitors is being concerned. The advance in the study of AGEs concept, its effect on diabetic cataract formation, the influence of AGEs inhibitor on diabetic cataract are summarized in this article.

?AIM:To study the changes of ocular surface in cataract patients with Meibomian gland dysfunction ( MGD) who treated with Meibomian gland massage before surgery.?METHODS: Totally 90 patients ( 93 eyes ) with cataract and MGD were randomly divided into two groups. Patients in experimental group were treated with hot compress and Meibomian gland massage every day before surgery, while the patients in the control group were not taken. Two groups of patients received phacoemulsification combined with intraocular lens implantation. Lid margin abnormalities, secretion characteristics, Schimer I test ( SⅠt) and tear film break-up time ( BUT ) were recorded and compared between two groups using slit lamp microscope inspection preoperatively and postoperatively 1wk.?RESULTS:In the control group, the postoperative score of eyelid margin and Meibomian gland secretion was increased significantly than preoperative, while the value of BUT and SⅠt was down significantly. Compared with control group, the postoperative score of eyelid margin shape and Meibomian gland secretion in the experimental group was decreased significantly, while the value of BUT and SIT improved significantly (P<0. 05).?CONCLUSION: Phacoemulsification can aggravate the Meibomian gland dysfunction and have some extent of effects on the ocular surface. Meibomian gland massage before surgery can significantly improve the function of Meibomian gland and the state of ocular surface in patients with MDG.

OBJECTIVETo observe the clinical efficacy differences among warming-promotion acupuncture, regular acupuncture and psychological care for post-earthquake depression.

METHODSNinety cases of post-earthquake depression in Gansu province were randomly divided into a warming-promotion acupuncture group, a regular acupuncture group and a care group, 30 cases in each one. The psychological treatment was applied in the care group; the regular acupuncture at Baihui (GV 20), Sishencong (EX-HN 1)), Fengchi (GB 20), Shenmen (HT 7), Yang-lingquan (GB 34), Taichong (LR 3) and Sanyinjiao (SP 6) was used in the regular acupuncture group; based on the treatment of regular acupuncture group, the warming-promotion acupuncture was applied in the warming-promotion acupuncture group, once a day. Ten days were taken as one course with an interval of two days between two courses. Totally 3 treatment courses were completed. The Hamilton depression (HAMD) scale before and after treatment in each group was observed while the efficacy was analyzed.

RESULTSAll three treatments were effective for depression. The total cured rate was 86.67% (26/30) in the warming-promotion acupuncture group, which was obviously superior to 50.00% (15/30) in the regular acupuncture group (P < 0.01) and 33.33% (10/30) in the care group (P < 0.001). After the treatment, the score of HAMD was all reduced in three groups, in which the effect in warming-promotion acupuncture group was superior to that in the regular acupuncture group and care group (9.02 +/- 2.37 vs 10.73 +/- 2.28 and 11.05 +/- 2.01, P < 0.05, P < 0.01).

CONCLUSIONThe warming-promotion acupuncture has positive effect on post-earthquake depression, which has special effect and is worthy of clinical generalization and application.

Objective To assess the value of C-reactive protein(CRP) for the prognosis of acute pulmonary embolism (PE). Methods 56 acute pulmonary embolism patients, confirmed by spiral computed tomography (sCT), magnetic resonance imaging(MRI), or pulmonary angiography (CTPA). CRP as well as electrocardiogram (ECG), echocardiography(UCG), blood gas analysis, were taken after admission. Results Among these patients,24 cases with higher CRP(≥10 mg/L),were diagnosed as massive (50.0%), sub-massive PE(45.8%), mini-massive (4.2%) or died(25.0%). 24 cases (100.0%) showed right heart dysfunction and 24 cases showed pulmonary hy-pertension on UCG, right ventricular 20 (83.8%) on ECG, 22 cases (91.7%) showed hypoxemia. 8 cases (33.3%) had syncope,and 9 cases (37.5%) had cardiogenic shock. CRP was lower than 10 mg/L in 32 patients, among whom,3 cases (9.4%) were with massive PE,6 cases (18.8%) were with sub-massive PE,23(71.8%) were with small PE,1 cases(6.3%) died. 13 (40.6%) had right heart dysfunction and 16(50.6%) had pulmona-ry hypertension on UCG, right ventricular on ECG in 15 cases (46.9%), hypoxemia in 11 cases (34.4%), syncope in 2 cases (6.3%), cardiogenic shock in 4 cases (12.5%). The occurrence of massive PE, mortality (P<0.01) and sub-massive PE (P<0.05)were statistically different between the groups with higher CRP and the groups with lower CRP. The ratio of right heart dysfunction, pulmonary hypertension, right ventricular overloading, hypoxemia had statistical significance (P<0.01). There was statistical significance in the occurrence of syncope, cardiogenic shock (P<0.05). Conclusions CRP can be used as a parameter for PE, and can be used to stratify risk levels for severi-ty and assess the effectiveness of treatment.

Objective To evaluate the value of continuous glucose monitoring system (CGMS) in the gestational patients with impaired glucose regulation. Methods The glucose level in the subcutaneous tissue was monitored by CGMS for 3 days in 6 patients with gestational diabetes mellitus (GDM) and 6 patients with gestational impaired glucose tolerance (GIGT). The fluctuation coefficient of blood glucose, percentage of hyperglycemic time, and percentage of hypoglycemic time were calculated. Results As shown by CGMS, the fluctuation coefficient of blood glucose, mean glucose level, percentage of hyperglycemic time, percentage of hypoglycemic time, mean fasting blood glucose, and mean postprandial blood glucose (PBG) levels were not significantly different between GDM group and GIGT group (P ＞ 0. 05). The time for reaching the peak PBG level ranged 90-120minutes in both two groups (P ＞ 0. 05). No sensor-related adverse events were noted. Conclusions It is safe to apply CGMS sensor in pregnant women. The blood glucose profiles are comparable between GDM and GIGT patients by CGMS; therefore, control of blood glucose should be equally strict in patients with GIGT as those with GDM.

Objective To investigate Lovastatin's effects on proliferation and adhesion of human umbilical vein endothelial cells (HUVECs). Methods Culture medium with different concentration of Lovastatin(0.001、0.01、0.1、1.0、10μmol/L) was prepared, HUVECs was cultured in 96 well-plate with the different medium. AT the point of 24,72 and 120 h, the cell's activity and quantity was assessed by MTT. HUVECs was cultured with Lovastatin in 6 well-plate for 24 hours, then collected the cells by trypsin digestion. The cells were seeded in 24 well-plate with 2×104/ml and adhering for 30 mins. Then counting the adhered cells in different wells. Results At 24 h, Lovastatin (0.01、 0.1 μmol/L ) promoted proliferation of HUVECs ( P ＜ 0.05 ); at 72 h, Lovastatin ( 1.0μmol/L) was positive accelerating cell growth(P＜ 0.05 ). While Lovastatin ( 10μmol/L) inhibited the proliferation significantly ( P ＜0.05 ) at 120 h. As HUVECs was cultured with Lovastatin for 24 hours, Lovastatin (0.1、1μmol/L) inhanced the adhesion capability of HUVECs significantly( P＜ 0.05 ). Conclusion Lovastatin had biphasic effects on proliferation and adhesion of HUVECs dependent on the concentration. Lovastatin (0.1、1.0 μmol/L) could promote the proliferation and adhesion, while at higher concentration ( 10.0μmol/L) it inhibits cell proliferation and adhesion.
