OBJECTIVE:To evaluate the economical efficiency of 3 therapeutic plans for acute upper respiratory tract infec-tion caused by group A β-hemolytic streptococcal (GAS). METHODS:In retrospective study,71 GAS positive patients with acute upper respiratory tract infection in our hospital during Mar. 2014-Mar. 2016 were selected and divided into group A(16 cases),B(30 cases),C(25 cases)according to medication method. Group A,B,C were given intramuscular injection of ben-zathine benzylpenicillin(1200000 U),oral administration of penicillin V potassium(0.5 g,q8 h,10 d)or oral administration of amoxicillin sulbactam(0.5 g,bid,10 d),respectively. Clinical efficacy and bacterial clearance were observed,and econom-ics of 3 therapeutic plans were evaluated. RESULTS:The cure rates of 3 groups were 87.50%,90.00%,and 92.00%;bacterial clearance rates were 88.24%,87.87%,and 92.59%,respectively;there was no statistical significance(P>0.05). Cost-minimi-zation analysis was adopted for pharmacoeconomic evaluation. The costs of 3 groups were 237.79,279.49,400.40 yuan,respec-tively. The cure rate and bacterial clearance rate of therapeutic plan C were the highest,but its cost also was the highest. The re-sults of sensitivity analysis were consistent with the results of cost-minimization analysis. CONCLUSIONS:The intramuscular in-jection of benzathine benzylpenicillin can be served as first choice therapeutic plan for recurrent upper respiratory tract infection caused by GAS and patients with rhenmatic fever risk. The patients who are reluctant to be treated with penicillin but guarantee medication time can take penicillin V potassium orally. The patients with poor efficacy of common penicillin can take amoxicillin sulbactam pivoxil.

AIM: As a human basement membrane-derived inhibitor of angiogenesis and tumor growth, canstatin has been paid great attention since it was isolated and identified in 2000. Canstatin significantly inhibited human endothelial cell migration and proliferation and induced apoptosis, suggesting that it might be a powerful and potential therapeutic molecule for atherosclerosis,unstable angina and tumor.

ObjectiveTo evaluate the retinal function with central serous chorioretinopathy (CSC) and the fellow eyes (mf-ERG).MethodsTwenty patients (40 eyes) with unilateral CSC, diagnosed by fluorescein angiography, were examined on each eye of the patients by mf-ERG multifocal electroretinography. The patients aged from 31 to 53 (13 men, 7 women; mean age, 41 years), and the CSC eyes had visual acuities of 0.2 to 0.8. None of the patients had significant abnormality in the fellow eyes with visual acuities of 0.8 to 1.5. Twenty-four healthy people (29 normal eyes with visual acuities of 1.0 and more and without any retinal diseases) were studied simultaneously as the normal control. The stimulus matrix of 61 hexagonal elements were grouped into 5 concentric rings from the fovea outward to 30? of the degree of visual field. The first-order responses of mf-ERG were recorded. The first negative wave (N 1-wave) and positive wave (P-wave) of the mf-ERG were measured. Amplitude intensities and latechies for the two configurations were calculated and compared.ResultsCompared with the control eyes, the responses were not only depressed severely in P 1- and N 1-wave amplitude intensities in the ring 1~3 in the CSC eyes with CSC (P0.05). There were no significant differences in N 1- and P 1-wave latencies in 5 concentric rings among the control eyes, the fellow eyes or the CSC eyes.ConclusionsCSC is a kind of macular disease involving both eyes. It may cause the decrease of retinal function in macular area of CSC eyes and also influence the retinal function in macular area of the fellow eyes. mf-ERG is a sensitive way in examining visual function.

Objective To elucidate the analgesic activity of the ethanol extracts from the root of Daphne genkwa (EERD). Methods The analgesic activity of EERD was evaluated by the effects on adjuvant-induced nociceptive response and paw swelling, the formation of PGE_2 and IL-1? in adjuvant arthritis (AA) rats, the activities of SOD and CAT, the levels of NO/iNOS in serum and brain tissue as well as by the effects on c-Fos protein expression in spinal cord of AA rats. Results EERD at used doses significantly delayed the adjuvant-induced nociceptive response and eased the paw swelling in AA rats. EERD also evidently inhibited the production of PGE_2 and IL-1?, and enhanced the activities of SOD and CAT in the tissue of paws being injected by adjuvant. Furthermore, it remarkably reduced the content of NO and inactivated the activity of iNOS in brain tissue of AA rats. In addition, EERD at used doses exhibited prominent inhibition on adjuvant-induced expression of c-Fos protein in the spinal cord of AA rats. Conclusion EERD is an effective agent for analgesia. The possible mechanisms for its analgesia might be the actions of inhibiting the production of PGE_2 and the release of IL-1?, reducing the activity of iNOS and hence the generation of NO in brain tissue, and blocking superoxidation through enhancing the activity of SOD and CAT.

Objective:To explore the clinical application in urinary system stones of the inspection technologies intravenous pyelography (IVP),computer tomography urography (CTU) and magnetic resonance urography (MRU). Methods:We collected 100 cases of urinary system stones on which 80 were carried out to IVP,60 to CTU and 35 to MRU,25 patients were implemented all 3 examinations. CTU and MRU are reconstructed with multi-level reorganization (MPR),curved projection reproduction (CPR),volume reproduction (VR) and the maximum intensity projection (MIP). Results:Stones were found in 73 patients of the 80 people by IVP,the diagnosis rate is 91.3 %. Stones were found in all the 60 patients except 1 by CTU with images direct and accurate,the diagnosis rate was 98.1 %. By the MRU,stones were found in 20 of the 35 patients at a display rate of 57.1 %,with images displayed in a low stone location signal,filling defect and the hydrocele circs of renal pelvis and ureter. Conclusion:IVP is a simple method,easy-to-patient acceptance and has a high detection rate of stones; CTU has a good image quality and the detection rate is higher than the stone IVP. By combining with the original cross-sectional image,the rate of diagnosis is up to 98%; as a non-invasive and no contrast agent approach,MRU is also very important in the diagnosis of stones.

Objective To determine whether leflunomide could control the proinflammatory cytokine expression induced by anthralin via inhibiting the activation of nuclear factor ?B (NF-?B). Methods The expression of NF-?B inhibitory protein ? (I?B?), was analyzed by using Western blot method. MTT assay and RT-PCR were used to assess the proliferating activity and mRNA expression of intercellular adhesion molecule-1 (ICAM-1) of HaCaT keratinocytes, respectively. Results Leflunomide inhibited the degradation of I?B? by anthralin, i.e. the activation of NF-?B signaling pathway, in a dose-dependent manner. The inhibition of keratinocyte growth by anthralin did not correlate with the activation of NF-?B. Under the experimental conditions used, leflunomide was shown to be able to significantly inhibit the over-expression of ICAM-1 on keratinocytes induced by anthralin; this inhibition occurred in a dose dependent manner. Conclusions Growth inhibition by topical anti-psoriatic medication anhtralin is unrelated to the NF-?B-dependent signaling pathway, and leflunomide can control ICAM-1 expression induced by anthralin via inhibiting the activation of NF-?B.

ObjectiveTo study the effects of two cryopreservation methods ( direct vapor nitrogen method and program freezing method) on the motility of post-thaw human sperm.MethodsThe 25 semen samples were taken from 25 donors from Shanghai Human Sperm Bank during May to July 2011,using straw as a frozen carrier, the semen samples contained modified glycerol-yolk-citrate ( GYC ) ( 1 ∶1 ) as cryoprotectant,after the liquefaction, each semen sample was divided into 2 groups,and separately cryopreserved by direct vapor nitrogen method and program freezing method.According to the recommended standardoftheWorldHealthOrganization, semensampleswereanalyzedbeforeandafter cryopreserving.Density,total motility,PR,motility parameters ( including VAL,VSL,VCL,BCF) were determinated by the IVOS sperm analyzer.Semen samples were stained by modified papanicolaou stain and 200 sperms of each sample were counted under microscope by manual analysis to calculate the rate of normal morphology sperm.The paired t test was used to compare the above indictors before and after cryopreserving in one method and after thawing between two methods.Results Before cryopreserving,the total motility,PR,VAL,VSL,VCL,BCF were(91.36±4.96)％,(81.28 ±6.41)％,(59.29 ±9.30) μm/s,(49.80±8.40) μm/s, (83.39 ± 15.70)μm/s, (16.68 ± 3.36)Hz respectively, and after cryopreserving by direct vapor nitrogen method the results were (46.04 ± 20.14)％,(40.22 ± 18.42 )％,(48.00± 11.60)μm/s,(41.11 ±8.50) μm/s,(71.55 ±17.19) μm/s,(15.94 ± 14.30) Hz respectively,the differences of the indictors above were observed with statistic significance except BCF ( t =11.324,11.958,4.266,3.964,3.620,0.258,P of BCF ＞0.05,P of others ＜0.05); and after cryopreserving by program freezing method,the results were(48.05 ± 18.27)％,(42.47 ± 15.62)％,(45.30 ± 6.51) μm/s,(38.08 ± 4.99) μm/s,(64.23 ± 11.75) μm/s,(14.00 ± 2.99) Hz respectively,the differences of the indictors above showed statistic significance (t =10.337,10.874,7.154,5.510,6.494,3.244,P ＜0.05).No significant differences were observed in the revival rate,total motility,PR and normal morphology sperm rate by using different methods (t =0.425,0.364,0.622,1.106,P ＞0.05).The results of VAL,VSL,VCL,BCF in direct vapor nitrogen method were higher than that in program freezing method,when the differences of VSL and VCL were observed with statistic significance(t =2.489,2.822,P ＜ 0.05 ).Conclusions Using straw as carrier is practicable.Direct vapor nitrogen method is easier to operate than program freezing method.Post-thaw sperm cryopreseved by direct vapor nitrogen method has higher motility parameters,thus making this method an ideal one for fast freezing.

AIM:To determine whether the vitreous cavity (VC) is capable of supporting the induction of deviant immune response to retinal soluble (S) antigen and to observe the influence of interleukin-1 (IL-1) on the immunologic properties of the VC. METHODS: Retinal S antigen was inoculated into the anterior chamber (AC) and VC in Wistar rats. Seven days after antigen inoculation, the recipient animals were immunized with S antigen and complete Freund's adjuvant. Delayed-type hypersensitivity (DTH) was then assessed by footpad challenge. To alter systemic immune conditions, IL-1 was administrated by intraperitoneal injection. RESULTS: Antigen-specific DTH did not develop in rats in which S antigen was injected into the AC and the VC. In contrast, strong DTH was elicited by S antigen injected into the AC and VC if IL-1 was administrated systemically for 7 consecutive days after the antigen challenge. CONCLUSION: The VC is capable of supporting immune deviation to soluble antigen by actively suppressing antigen-specific DTH. Systemic administration of exogenous IL-1 eliminates the capacity of the VC to support immune deviation inducing by soluble antigen injected locally.
