Objective To investigate the influence of different timing of surgery on patients with poor-grade intracranial aneurysm. Methods The clinical data of 86 patients with aneurysmal subarachnoid hemorrhage (Hunt-Hess gradeⅣ toⅤ)were analyzed retrospectively. The patients were divided into an ultra-early treatment group (the operative time within 24 h after onset;n=40),an early treatment group, (24 to 72 h after onset;n=27),and middle and late treatment group (>72 h after onset;n=19)according to the different timing of surgery. The prognosis of patients at 6 months after procedure was evaluated with the modified Rankin Scale (mRS)scores. The differences of the rate of good prognosis (mRS 0 to 2)and mortality in patients of the 3 groups were compared. Results (1 )The ratios of good prognosis in the ultra-early treatment group,early treatment group,and middle and late treatment group were 55. 0%(n=22),33. 3%(n=9),and 21. 1%(n=4),respectively. There were significant differences (P<0. 05). The mortality rate of the ultra-early treatment group (7. 5%)was lower than that of the early treatment group (25. 9%) or middle and late treatment group (42. 1%). There were significant differences (P<0. 05). (2)There were significant differences in the rate of good prognosis in different timing of surgery in patients with gradeⅣ(P<0. 05);there was no significant difference in the rate of good prognosis in patients with grade Ⅴ(P>0. 05). The mortality ratios in patients of the 3 groups were 2/18,4/11,and 6/11,respectively. There were significant differences (P<0. 05). Conclusion Ultra-early operation may benefit part of the patients with poor-grade aneurysm,particularly in patients with gradeⅣ. As for the patients with grade Ⅴ, ultra-early operation may help to reduce short-term mortality rate,however,the rate of vegetative state is high.

The research on regulation rules of traditional Chinese medicine (TCM) syndrome was the core of TCM syndrome information. It was thought that the constitution identification which provided the technology for evaluating health status was one of the bases in drawing the curve of conditional standard of syndrome. It was fitted and analyzed by the curve of conditional evolution of syndrome through establishing the curve of conditional standard of TCM constitution theory. It was the key technology of realizing the dynamical evaluation of TCM clinical effect.

Objective To investigate the control status of glycosylated hemoglobin (HbA1c) in the middle aged and elderly patients with type 2 diabetes mellitus (T2DM) in Lanzhou communities and analyze its influencing factors.Methods A total of 1 120 individuals having diagnosed T2DM aged 40-75 years in Lanzhou communities were selected.Questionnaire was conducted.Height,weight,blood pressure and lipid were examined.Body mass index (BM1) was calculated.The index were analyzed.Results The patients with HbA1c less than 7.0％ were 453 cases (40.4％,453/1 120),and HbA1c more than or equal to 7.0％ were 667cases (59.6％,667/1 120).The target rate of HbA1c in the patients receiving life style,one oral antidiabetic drug,more oral antidiabetic drug,insulin therapy were 49.2％(94/191),45.7％(182/398),41.5％(88/212) and 27.9％(89/319),respectively.The target rate of HbA1c were 38.6％(192/298),32.2％(49/152),32.7％(49/150),27.0％(85/315) in the patients overweight or obese,with macro or micro vascular complication,and 60.0％ (12/20),44.4％(200/450),41.6％(404/970),45.7％(368/805) in the patients without overweight or obese and macro or micro vascular complication,and there were significant differences (P ＜ 0.01 or ＜ 0.05).Multivariate Logistic regression analysis showed that the extension duration of diabetes,increased BMI,combining with macro or micro vascular complication and gradual strengthening antidiabetic treatment were independent risk factors for HbA1c target (P ＜ 0.05).Conclusions Current status of HbA1c control in the middle aged and elderly patients with T2DM in Lanzhou communities is not optimistic,which is affected by many factors,suggesting that professional education on management should be further strengthened.And optimal treatment programs and individualized comprehensive treatment are needed for most patients to improve glycemic control.

AIM:To observe and analyze the change of visual field and retinal nerve fiber layer thickness of primary open-angle glaucoma ( POAG ) after the Ex-press glaucoma shunt implantation.
●METHODS:A total of 14 patients (24 eyes) with POAG were underwent Ex-press glaucoma shunt implantation. Visual acuity, intraocular pressure ( lOP ) , mean defect ( MD) , pattern standard deviation ( PSD ) , retinal nerve fiber layer thickness ( RNFLT ) , and corneal endothelial cell number were collected preoperatively. Visual acuity and lOP were collected in 1wk, 1 and 3mo postoperatively respectively. Also, MD, PSD, RNFLT, and corneal endothelial cell number were collected preoperatively and 3mo postoperatively respectively. Complication, the additional treatment, success rate were analyzed.
●RESULTS:There was no significant difference (P>0. 05) in visual acuity preoperative and postoperative 1wk, 1, 3mo. Visual acuity did not significantly reduce after operation. Compared with preoperative, there was significant decreased (P<0. 05) in lOP after 1wk, 1, 3mo postoperative, respectively. lOP keep stead in postoperative 3mo. The reduction of RNFLT had significant difference (P<0. 05) between preoperative and postoperative 3mo. Compared with preoperation, MD and PSD had no significant difference ( P > 0. 05 ) after postoperative 3mo. Corneal endothelial cell number decrease had significant difference (Z=-2. 585, P=0. 01) between preoperative and postoperative 3mo. Success rate: complete success: 79. 2% ( 19 eyes ); partial success:8. 3% (2 eyes);failure:12. 5% (3 eyes).
●CONCLUSION: Ex-press glaucoma shunt implantation could efficiently decrease the lOP in POAG patients. Although it results in reduction of RNFLT in short time. The visual acuity and visual field keep stable after operation. lt is a safe and effective device for treating primary open-angle glaucoma.

Clove oil and turmeric oil were absorbed by mesoporous carbon. The absorption ratio of mesoporous carbon to volatile oil was optimized with the eugenol yield and curcumol yield as criteria Curing powder was characterized by scanning electron microscopy (SEM) and differential scanning calorietry (DSC). The effects of mesoporous carbon on dissolution in vitro and thermal stability of active components were studied. They reached high adsorption rate when the absorption ratio of mesoporous carbon to volatile oil was 1:1. When volatile oil was absorbed, dissolution rate of active components had a little improvement and their thermal stability improved after volatile oil was absorbed by the loss rate decreasing more than 50%. Absorbing herbal volatile oil with mesoporous carbon deserves further studying.

OBJECTIVETo observe the distribution of constitution types of Chinese medicine (CM) in patients with osteonecrosis of femoral head (ONFH).

METHODSTotally 130 ONFH patients were recruited. Constitution types of CM were identified in all patients. Distribution features of constitution types of CM in ONFH patients were observed. The differences of distribution in gender, age, single or bilateral hips, course of disease, staging, cause, and region were also analyzed.

RESULTSSeventy patients were of complicated constitutions, while 60 patients were of single constitution. Among the 60 single constitution cases, yang-deficiency constitution [18 (13.9%)], damp-heat constitution [10 (7.7%)], blood-stasis constitution [7 (5.4%)], and qi-deficiency constitution [7 (5.4%)] were mainly distributed. Of the complicated constitutions, yang-deficiency dominated constitution occupied the top ratio [30 (23.1%)], followed by blood-stasis dominated constitution [15 (11.5%)], damp-heat dominated constitution [9 (6.9%)]. By putting them together, yang-deficiency constitution occupied the top constitution of CM [48 (36.9%)], followed by blood-stasis constitution [ 22 (16.9%)] and damp-heat constitution [19 (14.6%)]. The aforesaid three constitutions accounted for 68.5% of the total. There were no statistical distribution differences in gender, age, single or bilateral hips, course of disease, staging, or cause.

CONCLUSIONYang-deficiency constitution, damp-heat constitution, and blood-stasis constitution were liable constitutions of CM in ONFH patients.
