AIM:To evaluate the efficacy and safety of Sub-tenon's anesthesia for compound trabeculectomy with high intraocular pressure.
METHODS: Forty - six eyes ( 46 cases ) of primary glaucoma received compound trabeculectomy under Sub-tenon's anesthesia, whose preoperative intraocular pressure were higher than normal after 24 to 48h of combined medication. Both efficacy and complication of the anesthesia were studied.
RESULTS: One minute after anesthetic injection, all cases were able to achieve the effect of analgesia and eye brake. During the operation, 0 level of anesthesia effect included 35 eyes ( 76%) , 1 level of anesthesia effect included 10 eyes ( 22%) , 2 level of anesthesia effect included 1 eye(2%). Only 1 case of these patients needed to add the surface anesthetic once, and other cases were successfully operatedunder Sub-tenon's anesthesia. The total effective rate was 98%. No anesthesia complications occurred in all cases.
CONCLUSION: Sub - Tenon's anesthesia is safe, effective, simple and quick for compound trabeculectomy with high intraocular pressure.

OBJECTIVE: To investigate the preparation of novel cationic liposomes encapsulating siRNA, and evaluate their silence efficiency on target mRNA in LNCap cells. METHODS: Reverse evaporation technique was used to prepare the cationic liposomes. Protamine and calf thymus DNA were added to increase the encapsulation efficiency. The physicochemical property of the liposomes was evaluated. Human prostate cancer cells, LNCap, were used as the cell model. The silence efficiency on target gene in LNCap cells was evaluated with lipofectamine 2000 as the positive control. RESULTS: The optimum liposomes were obtained when the ratio of DOTAP and cholesterol was 3:1 and the ratio of liposomes and siRNA was 300:1. The size distribution and Zeta potential of the liposomes were (117 ± 4.3) nm and (43 ± 3.6) mV, respectively. The liposomes significantly improved siRNA accumulation in cells. CONCLUSION: The novel cationic liposome showed high transfection efficiency and distinct silence efficiency for target gene, which are expected to become a highly effective drug delivery system for anti-cancer drugs.

This paper discussed AIDS epidemic sityation and it's tendency, AIDS harmful-ness to human beings health and social economic development. The dangerous factors of AIDS epidemic in china is pointed out. prsvent and treatment AIDS is urgency.

Objective:To establish the quality standard for Kangniling Capsules. Methods: Cordyceps, Radix Notoginseng and Radix Sophorae Flavescentis in this prescription were identified by TLC. Ginsenoside Rg1 was determined by HPLC. Results: Cordyceps, Radix Notoginseng and Radix Sophorae Flavescentis could be detected by TLC. The content limit of ginsenoside Rg1 shouldn't be lower than 0.20mg per capsule. Conclusions: The established method is simple, feasible and reproducible. The quality of Kangniling Capsule can be controlled by the method.

Objective This present study explores and evaluates the effect of preliminary implementation in the clinical therapy programs for patients with chronic Keshan disease (CKD) in the disease seriously-affected endemic areas.Methods In 2010,seventy-six CKD patients with heart failure were chosen from Huangling and Xunyi Counties in Shaanxi Province,where incidences of CKD were high.Besides taking sodium selenite,all patients were given treatment with fixed prescription,which included angiotensin-converting enzyme inhibitor (captopril),β-blocker (propranolol),diuretics (hydrochlorothiazide,spironolactone) and cardiac (digoxin) for 4 months.The changes before and after treatment were analyzed,which included the changes of heart function by the United States of America New York Heart Association(NYHA) fractionation,cardiothoracic ratio,electrocardiogram,left ventricular ejection fraction(EF) and fractional shortening(FS).The therapeutic effect was subsequently evaluated.Results Seventy-four cases of the seventy-six CKD patients completed the treatment observation.The improvement rate of heart function was 81.1％ (60/74) after treatment.The elimination rates of ectopic rhythm,conduction block and ST-T changes were 37.5％ (9/24),2.7％ (1/36) and 26.9％ (7/26),respectively.The cardiothoracic ratios of heart function NYHA Ⅱ,Ⅲ and Ⅳ were 0.504 ± 0.051,0.572 ± 0.054 and 0.632 ± 0.063 before treatment.After treatment,the cardiothoracic ratios were 0.486 ± 0.048,0.538 ± 0.046 and 0.607 ± 0.048,which were reduced in all groups (t =2.643,6.641,3.005,all P ＜ 0.05),while the D-value of cardiothoracic ratio changes before and after treatment was not significantly different(F =3.005,P ＞ 0.05).Both the mild reduction group(35％≤EF ＜ 50％) and the moderate-severe group(EF ＜ 35％) EF were (43.62 ± 4.58)％,(27.57 ± 3.69)％ before treatment and were (48.21 ± 10.01)％,(36.57 ± 6.60)％ after treatment,EF were increased in the two groups,while the changes before and after treatment were significantly different(t =-2.911,-3.334,all P＜ 0.05).The EF D-value of the two groups was (4.59 ± 8.48)％ before treatment and was (9.00 ± 7.14)％ after treatment,which were not significantly different(P ＞ 0.05).FS was higher compared with pre-treatment in FS reduction group(FS ＜ 25％) and the changes before and after treatment[(19.75 ± 2.88)％,(21.92 ± 5.67)％] were significantly different(t =-2.297,P ＜ 0.05).Conclusions This study shows that the feasibility of clinical treatment of patients with CKD is very promising.The treatment of fixed prescription is effective.
