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 Our aim is to investigate the effects of lndomethacin on the expression of VEGF and the change of Micmves-sel Density(MVD)in remnant kidney of rats with 5/6 subtotal nephrectomy(STNx).Methods The renal subtotal ablation model was established by surgically 5/6 renal resection of the male Spragne-Dawley(SD)rats.Three groups were divided in our experimental protocol,including Sham,STNx and STNxI group.At the 8th week after gastric gavage,pathological changes of the remnant kidney were evaluated.Immunohistachemistry were used to examine the expression ofVEGF and MVD in the remnant kidney.Results At the 8th week after gastric gavage,only Up was significant decreased(P<0.05).TIS in Indomethacin group WaS significandy increased(P<0.05)and the preitu bular capillary density wa$significant decreased(P<0.05),compared with STNx group.Although BUN,Cr,the remnant kidney glomerulus's GSI were also decreased,the difference was not statistically significant(P>0.05).The glomendus～capillary density had no signifi-cant difference(P>0.05).In all rats,the expression of VEGF was positive correlated with capillary density between glomemlus and tubu-lointerstitimn(P<0.05).Conclusions Iadomethacin Can decrease UP in remnant kidney of rats with 5/6 subtotal nephrectemy(ST-Nx),and decrease the preitubular capillary density and aggravate mbulointerstitial injury at the same time.

Objective To investigate the expression of p-MNK1 in non-small cell lung cancer and its relationship with clinic pathological features and prognosis.Methods The level of p-MNK1 in 115 cases of nonsmall cell lung cancer was detected by tissue microarray technique and immunohistochemistry technique.Results The level of p-MNK 1 in non-small cell lung cancer was correlated with cancer tissue type (P ＜ 0.05),clinical stage (P ＜ 0.05),lymph node metastasis (P ＜ 0.01) and prognosis (P ＜ 0.05).Cox multiple regression analysis showed that p-MNK1 expression was an independent prognostic factor for non-small cell lung cancer (P ＜ 0.01).Conclusion The level of p-MNK1 in non-small cell lung cancer is associated with poor prognosis.It can be used as an independent prognostic marker and a new therapeutic target.

The recombination clones contained CFP, LTB-ST foreign gene were screening by PCR using individual bacterial colonies as template, the aimed band was amplified from positive clones, the result was as well as plasmid PCR. The selecting of agrobacterium transformed with recombination plasmid could also use this method of PCR screening of individual bacterial colonies. The result of individual bacterial colonies PCR was as well as that of PCR using bacterial solution as template. It showed that the method individual bacterial colonies PCR was an efficient, easy one that characterized recombination clones.

To study the in situ intestinal absorption of five oligosaccharides contained in Morinda officinalis How. (sucrose, kestose, nystose, 1F-Fructofuranosyinystose and Bajijiasu). The absorption of the five oligosaccharides in small intestine (duodenum, jejunum and ileum) and colon of rats and their contents were investigated by using in situ single-pass perfusion model and HPLC-ELSD. The effects of drug concentration, pH in perfusate and P-glycoprotein inhibitor on the intestinal absorption were investigated to define the intestinal absorption mechanism of the five oligosaccharides in rats. According to the results, all of the five oligosaccharides were absorbed in the whole intestine, and their absorption rates were affected by the pH of the perfusion solution, drug concentration and intestinal segments. Verapamil Hydrochloride could significantly increase the absorptive amount of sucrose and Bajijiasu, suggesting sucrose and Bajijiasu are P-gp's substrate. The five oligosaccharides are absorbed mainly through passive diffusion in the intestinal segments, without saturated absorption. They are absorbed well in all intestines and mainly in duodenum and jejunum.

OBJECTIVETo evaluate in vivo pharmacokinetics of Ophiopogonis Radix polysaccharide MDG-1 oily suspension injection prepared with different prescriptions in rats, and explore the feasibility of the long-acting drug delivery of MDG-1 Injection by using the oily suspension drug release system.

METHODMDG-1 microparticles were prepared by the anti-solvent precipitation method. Their size and size distribution were characterized. Castor oil with a high viscosity or aluminum stearate were added into soybean oil with a low viscosity, in order to prepare oily media with different viscosities, detect their rheological properties and screen out superior prescriptions for in vivo evaluation.

RESULTThe average size of microparticles was 21.81 microm, and the span between them was 2.63. The in vivo evaluation was conducted for prescriptions of mixed oil (soybean oil/castor oil, 2: 3) and soybean oils gelled by 2% and 4% aluminium stearate. Among them, the prescription of soybean gelled by 4% aluminium stearate could significantly reduce C(max) and prolong the apparent t1/2, with the MDG-1 release time of several days.

CONCLUSIONIt is feasible to achieve the long-acting MDG-1 drug delivery by using oily media with a high viscosity.

Objective To study the characteristics,diagnosis and therapeutic principles of postmenopausal ovarian masses. Methods The clinical data of 261 postmenopausal women were reviewed to understand the characteristics,best diagnostic measures and therapeutic principles of postmenopausal ovarian masses. Results Among the post-(menopausal) ovarian masses,27.9% were malignant and 5.36% were boundary.No symptoms were found in(44.4%) of the patients.Before operation,the characteristics of masses can be identified by B-mode sonography,color Doppler sonography and CA-125 detection.Simple adnexectomy was performed for most of the benign ovarian masses and cytoreductive surgery for malignancies. Conclusion Regular examinations should be performed on postmenopausal women for ovarian masses,and B-mode sonography,color Doppler sonography and CA-125 detection be employed in the case of necessity.Once the ovarian masses are confirmed,surgeries may be the best choice for patients.

This article was aimed to study the optimum technological conditions of roller compaction of FKⅣ gran-ules. This experimentation compared content of two granule preparation techniques which were the dry process gran-ulation and the wet process granulation, and adopted L9(34) orthogonal experiment to study the technological parame-ters of FKⅣ granules. The dry process granulation was selected. And factors such as roller pressure, roller speedand moisture content of power, which influence the result of granule yield were also studied in the dry process gran-ulation. The results showed that the optimum technological conditions were roller pressure at 5.0 Mpa, roller speed at 400 rpm, and moisture content of power at 3.0%. It was concluded that the roller compaction process of FKⅣ gran-ules was feasible in production which was able to meet the requirement of production.
