· ATM:To analyze bacterial spectrum and drug sensitivity in conjunctival sac of cataract patients of Kazak.
· METHODS:A total of 538 cases of conjunctival sac secretion in cataract patients of Kazak were collected.The samples were cultured and their sensibilities to antibiotics were tested.
· RESULTS: The bacterial culture was positive in 214 cases.The positive rate was 39.8%. The variety of pathogenic bacteria were mainly made up of gram positive cocci ( 88.3%), and most of them were Staphylococcus epidermidis ( 66.4%), followed by Micrococcus(9.8%).Sex had no effect on conjunctival bacteria rate in the cataract patients of Kazak, while age, place of residence had an effect on camier rate. The camier rate of conjunctival bacteria was significantly higher in people over 60 years old than that in people with age between 40 to 59 years old.And the people from city had a significant lower bacteria positive rate than those from countryside and pastoral. Most of grams were sensitive to Vancomycin, Teicoplanin, Rifampicin, Duly cloth mildew mutual and Amikacin, the tolerance was less than 20%, and they usually had higher tolerance to Penicillin, Erythromycin, Tetracycline and Chloramphenicol (>70%) .
·CONCLUSlON:Gram positivecocci is the most common bacteria in conjunctival sac in cataract patients of Kazak. Staphylococcus epidermidis was most common, followed by Micrococcus.The germ-carrying rate of conjunctival SAC in Kazakh population is associated with the patient’s age and area of residence.The clinical use of antibacterial drugs should be strictly grasp the indications, to reduce the incidence of bacterial resistance.

Background Macular hole retinal detachment(MHRD) causes severe decrease of vision.Pars plana vitrectomy has been applied for MHRD.Silicone oil and C3F8 have been used as intraocular tamponade materials,while there are still controversity on their efficacy.Objective This trial was to evaluate the efficacy of vitreous surgery combined with silicone oil or C3F8 tamponade for patients with MHRD in highly myopic eyes.Methods A retrospective case-controlled study was designed.Fifty-one patients who underwent vitrectomy with intraocular tamponade were retrospectively analyzed.The best corrected visual acuity(BCVA) before and after surgery were examined and campared between two groups.The rate of recurrent RD and macular hole closed were analyzed.Results There was no significant difference in BCVA between silicone oil group and C3F8 tamponade group before and after surgery(U=266.000,P =0.286 ; U =205.000,P =0.029).The BCVA after surgery was elevated in both groups (Z=-2.729,P =0.006 ; Z =-3.273,P =0.001).The rates of recurrent RD and macular hole closed were no difference between two groups(P=0.894,1.000).There were no other complications but cataract.Conclusions C3F8 tamponade of MHRD in high myopic eyes show the same efficacy as silicone oil tamponade.

Licorice-gypsum (gancao-shigao, GC-SG) drug pair was used as the research object, using supramolecular chemistry to explore the scientific connotation of combining herbal medicine GC with insoluble mineral medicine SG in clinical application of traditional Chinese medicine. ① The Tyndall effect, microscopic morphology and particle size of the single and co-decocted of GC and SG were observed, the paste content and conductivity were determined, and the interaction between GC and SG was detected by isothermal titration calorimetry (ITC) and infrared absorption spectroscopy (IR). ② Calcium chloride (CaCl₂), a soluble calcium salt of equal gypsum quality, was used instead of SG with GC for co-decocting to explore the effect of calcium salt content on the water decocting, and the characteristics were combined with the Tyndall effect, microscopic morphology, paste content and conductivity. ITC and IR techniques were used to detect the interaction between the two, and the interaction between them was detected by ITC and IR. The zeta potential and ultraviolet-visible spectrophotometry (UV-vis) of GC-SG and GC-CaCl₂ co-decoction were compared, and the inorganic and organic components in the co-decoction were detected by inductively coupled plasma optical emission spectrometer (ICP-OES) and high performance liquid chromatography (HPLC). The results showed: ① Compared with the liquid phase of single decoction, GC-SG co-decoction had more obvious Tyndall effect, and showed uniform spherical nanoparticles under electron microscope. Physical characterization results such as paste content and conductivity showed that co-decoction promoted the dissolution of each other's components; ITC and IR results showed that there was strong interaction between GC and SG, which preliminatively indicated that GC and SG co-decoction promoted the formation of uniform and stable supramolecular system of traditional Chinese medicine. ② When soluble calcium salt was used to substitute insoluble SG with GC for co-decocting, a stronger but astigmatic light path appeared than single decocting solution, the zeta potential was reduced, and a large number of accumulated polymers were formed. The results of paste content and conductivity showed that the dissolution of the co-decocting component was reduced than the single decocting component. ITC, UV-vis and IR results showed that there was interaction between GC with Ca²⁺ and SG. The formation of polysink indicated that a large amount of soluble calcium salt would destroy the stability of supramolecular Chinese medicine. The results of ICP-OES and HPLC showed that the glycyrrhizic acid (GA) content of the former lower than the latter, which was related to the formation of a large number of polycondensates with the increase of Ca²⁺ concentration and the decrease of the dissolution of GA and other active ingredients. This study indicates that the compatibility of GC and SG can form a uniform and stable supramolecular system of traditional Chinese medicine. Calcium salt, the main component of SG, is taken as the starting point. Excessive soluble Ca²⁺ can promote the aggregation of active ingredients such as GA, so as to reveal the scientific connotation of the compatibility of GC and SG, an insoluble mineral medicine.

Twenty Newcastle disease virus(NDV)strains were isolated from diseased chicken and geese in field outbreaks during 2005 and 2006 in some regions of Jiangsu and Guangxi,and the antigenic analysis of the all NDV isolates had been done based on the reaction spectrum with a panel of monoclonal antibodies to the HN glycoprotein.The entire ORFs encoding HN protein of these NDV isolates were amplified by RT-PCR successfully,cloned and sequenced.The resultant sequences of HN genes of 13 isolates of chicken origin and 7 isolates of goose origin were gained and analyzed.The results of reaction spectrum showed that there were some distinct differences in the antigenic epitopes among the 20 NDV isolates.And the sequences revealed that the coding regions of the HN genes of these isolates all consisted of 1716 nt characteristic of virulent strains of NDV,coding for 571 amino acids.Neucleotides sequence homology were found to be from 94.8%to 100%among 18 NDV isolates of genotypeⅦ,and the neucleotides sequence homology between all the isolates and the other genotypeⅦstrains of recent years in China ranged from 92.1%to 99.6%.The deduced amino acid sequences and the receptor-binding regions of HN proteins between the NDV isolates of chicken origin and of goose origin were compared and analyzed.The results showed that some unique amino acid substitutions were found in the genome of the NDV isolates,and the close genetic similarity provided evidence for epidemiological linkage between the NDV isolates of chicken origin and of goose origin in the same period.
