Objective To compare the effect of different puncture positions in the combined spinal epidural anesthesia (CSEA)in cesarean section.Methods Ninety uterogestation women under-going elective Caesarean section were randomly divided into two groups,45 in each group.L3-4 inter-vertebral space was selected as puncture point.Group R kept right lateral position for two minutes af-ter puncture and turned 30°left tilt supine position until ready for surgery.Group L was turned to su-pine position after left lateral punctured and then turned to 30 left tilt supine position until ready for surgery.1% ropivacaine 1.5 ml+ 10% glucose 0.5 ml was used for spinal anesthesia.The sensory block level and adverse reaction within 1 5 min after the spinal anesthesia were observed,and the neo-natal Apgar score and the pH value of umbilical artery blood were recorded.Results The final block level of the group R was significantly lower than group L,and the time achieving final block height was significantly shorter than that in group L(P <0.05 ).The ephedrine dosage of group R 0 (0-6) mg was significantly lower than that of group L6 (0-12)mg (P <0.05).The PH value of umbilical artery blood in group R was significantly higher than that in group L (P <0.05).There was no sig-nificant difference in neonatal Apgar score.Conclusion In Cesarean section,keeping right lateral puncture position for two minutes after infusion and then turning 30° left tilt supine position can a-chieve better effects than 30°left tilt supine position immediately after puncturing.

Objective To investigate the origin of prostatic blood-supply by digital subtraction angiography (DSA) and provide references for the arterial embolization of prostatic hyperplasia. Methods A total of 72 male patients with successful selective and super-selective prostatic arterial catheterization angiographies were observed and recorded the original arterial blood-supply of the prostate, number of the prostatic arteries and the predominant blood supply. Results The blood-supply of prostate is very complicated including the original prostatic arterial supply from the inferior vesicle arteries (69); the internal iliac arteries (63); the internal pudendal arteries (52); the inferior rectum arteries (29); the superior vesicle arteries (14). The predominant arterial supply include the internal iliac arteries (37); the inferior vesicle arteries (20); the internal pudendal arteries (6) and the inferior rectum arteries (2). Conclusion Arterial contrast medium angiography can correctly demonstrate and assess the original arterial supply of prostate, providing significant guidance for further interventional embolization.

Objective To evaluate the efficacy of tegaserod in treating overlapping symptoms of chronic constipation and dyspepsia or reflux.Methods Eighty eight patients with overlapping symptom were enrolled and randomly divided into:tegaserod group(TEG group,received tegaserod 6 mg bid), PPI group(esomeprazole 40 mg qd)and combined group(tegaserod 6 mg bid and esomeprazole 40 mg qd).Esomeprazole was taken 30 min-prior to the meals in the morning.Each group was treated for 4 weeks.Endpoints to evaluate the clinical efficacy including complete relief rates(CRRs)of epigastric symptoms,the total scores of gastrointestinal symptoms,gastric emptying and colonic transit time and gastric sensation.Results The total scores of gastrointestinal symptoms were all significantly decreased in three groups after four-week therapy,which were more decreased markedly in TEG group(7.23?3.13)and the combined group(5.13?2.26)than that in PPI group(13.58?2.02,P

Objective To study normal flora components of conjunctiva, explore the relationship between normal flora and ocu- lar bacterial infections.Methods The data of 1 198 bacterial cultures of conjunctiva in non-infectious cataract patients were re- viewed and compared with the results of 985 specimens of conjunctivitis, keratitis and endophthalmitis from January 2000 to December 2004.Results Positive culture of conjunctiva in non-infectious cataract patients was 628 in 1 198 specimens (52.4%).These bacteria including gram-positive cocci and gram-neganve bacilli constituted the normal flora of conjunctiva. Staphylococcus epidermidis was the predominant bacteria (51.1%, 341/667) and its prevalence increased during this 5-year period.S.epidermidis and S.aureus were also the most frequently isolated pathogens in specimens of conjunctivitis, keratitis and endophthalmitis.The correlation was statistically significant between the positive rate in normal eye and conjunctivitis or keratitis in terms of these two species, but not statistically significant between normal eye and endophthalmitis.The resistance rate of normal flora of conjunctiva to ampicillin, amikacin, tobramycin, ciprofloxacin, and ofloxacin increased year by year. The resistance rate to gentamicin and the combination of two drugs decreased.The changing resistant pattern was similar in pa- tients with eye infection.Conclusions There is a close relationship between the normal flora S.aureus and S.epidermidis of conjunctiva and the bacterial infection of ocular surface, but no significant correlation between normal flora and the pathogen of endophthalmitis.

This study aims to assess if adverse drug reactions (ADRs) to Kudiezi injection are allergic in origin. Hospital information system (HIS) data from 18 hospitals in China were used to carry out a nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving Kudiezi injection. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on solvents had a significant effect, P values were 0.005 5 and < 0.000 1 on suspected cases of allergic reactions. For the first subgroup analysis, we found using other eight injections at the same time as Kudiezi injection could be risk factors in suspected cases of allergic reactions. For the second subgroup analysis combining using mannitol or fructose could increase risks. Based on this current research, condition on admission as well as the concomitant use of some other drugs may be the risk factors in suspected cases of allergic reactions. However, further research for verification is required. This study can provide guidance for safe clinical practice in using Kudiezi injection.

AIM:To compare the early results of different kinds of transepithelial corneal collagen cross-linking (TE-CXL) in the treatment of progressive keratoconus.METHODS:Retrospective study.Twenty four patients (34 eyes) who were diagnosed with progressive keratoconus were divided into three groups.And 10 eyes in hypotonic CXL group received the treatment of hypotonic corneal collagen cross-linking;14 eyes in Ⅰ-CXL 5min group received the treatment of iontophoresis corneal collagen cross-linking for 5min,and 10 eyes from the Ⅰ-CXL 10min group received the treatment of iontophoresis corneal collagen cross-linking for 10min.Uncorrected distance visual acuity,corrected distance visual acuity,Pentacam,in vivo scanning laser confocal microscopy and anterior segment optical coherence tomography were examined before and after 1wk,1,3 and 6mo postoperatively.RESULTS:Six months postoperatively,corrected distance visual acuity (CDVA) (LogMAR) in Ⅰ-CXL 10min group increased by-0.21 ± 0.23 (t =2.735,P=0.026);Kmax decreased by 2.32± 5.21D (t=1.40,P=0.193),but the differences were not statistically significant.Uncorrected distance visual acuity (UDVA),CDVA and Kmax in hypotonic CXL group and Ⅰ-CXL 5min group were stable,the differences were not statistically significant.The depth of demarcation line was 152.7±42.9μ m in hypotonic CXL group,213.6±42.3μ m in Ⅰ-CXL 5min group and 237.0±46.4μ m in Ⅰ-CXL 10min group 1wk after the surgery,the differences among groups were statistically significant (F =7.111,P =0.006).The phenomenon of stroma cell apotosis-activate regeneration in Ⅰ-CXL 10min group was the most significant after the surgery.The changes of corneal thinnest thickness and endothelial cell density in three groups were stable.CONCLUSION:Three kinds of transepithelial CXL can halt the progression of keratoconus,among which the reaction of corneal tissue in iontophoresis CXL for 10min is the most obvious.

In this study,nearly 200 endophytic bacteria were isolated from different part of Huperzia serrata, over 60 bacterium with clear antifungal activity were selected from those cultures.Among them,strain H-6 exhibited the highest antifungal activity which was strongly inhibits the growth of many plant pathogenic fungi such as Sclerotinia scleroliorum,Fusarium graminearumt,Sclerotinia libertiana,Phytophthora capsici Leonia and Sesame fusarium wilt.According to the characteristics of morphology,physiology and biochem- istry tests and the comparison of 16S rDNA sequence,the strain H-6 was similar to the Burkholderia.So strain H-6 was identified as Burkholderia sp.H-6.The results also showed that Burkholderia sp.H-6 was markedly different from Burkholderia cepacia that was applied widely in agriculture as antagonistic bacteria. The medium and culture conditions of the strain all were optimized by single factor and orthogonal experiments.In the investigation of the culture condition,growth was carried out in a basal medium(potato juice)and gradually supplemented with the various ingredients to be investigated.The major ingredients be- ing investigated included carbon sources and nitrogen sources.The optimal antifungal activity production condition is growth in a medium(potato juice with 2.5%mannitol and 0.1%NaNO3),initial pH 4.0 at 28℃.

The type of basic media and the contents of plant growth substances were investigated by orthogonal design experiment,and also the effects of different culture conditions on the growth of suspension cells and the accumulation of total flavonoids in Eucommia ulmoides were studied.The results showed that B5 medium supplemented with 0.5mg/L NAA,0.6mg/L 6-BA and 30g/L sucrose,at initial pH 5.0～5.5,20g(FW)/L inoculation quantity and 110 r/min of rotation speed was a preferable culture conditions for E.ulmoides suspension cells growth and flavonoids synthesis.The results of metabolic kinetics analysis for E.ulmoides cell suspension culture showed that the logistic and Luedeking-Piret equations can be used for describing the kinetics of cell growth,sucrose consumption and flavonoids production during the process.The maximum specific growth rate(?m),the actual growth yield based on sucrose(YG) and maintenance coefficient(m) were 0.417/d,0.619g/g and 0.0206g/(g?d-1) respectively.All these outcomes could give a basis for establishing the suspension cell culture of E.ulmoides and production of the natural active components in large-scale.

Objective To observe adhesion and growth of Sehwann cells(SCs) on small intestinal submueosa(SIS) and study the bioeompatibility of SIS with SCs.Methods The SCs of SD neonate rat were isolated and cultured in vitro,then were seeded on prepared SIS.At different times,the adhesion,growth and proliferation of SCs on SIS were observed by phase contrast microscope,histological examination,scanning e- lectron microscope and transmission electron microscope.Results By phase contrast microscope,SCs grew well on the edge of SIS after 3 and 5 days.SCs adhered tightly on the surface of SIS after 5 days through histo- logical examination.By scanning electron microscope,on the surface of SIS,SCs grew and adhered actively, prominence of cells body were obvious.They connected end-to-end with each other or arranged in clusters. Protein granules were secreted on cells surface.By transmission electron microscope,SCs grew in good condi- tion and adhered tightly on the surface of SIS.At the interface of SCs and SIS,prominence was seen to contact with SIS in the bottom of cell body.Conclusion SCs are able to adhere and grow well on the surface of SIS.As a scaffold,SIS has good biocompatibility with SCs.
