Objective To compare the effect of lacrimal ducts retrograde intubation and dacryocystorhinosto-my in treating chronic dacryocystitis.Methods 104 patients with chronic dacryocystitis were selected and divided into observation group and control group by lottery.There were 64 cases in observation group and 40 cases in control group.Lacrimal ducts retrograde intubation was given in observation group,while dacryocystorhinostomy was given in control group.Same postoperative care was given in both two groups.The surgery related conditions and effect of treat-ment were compared.Results There were 63 effective cases in the observation group in 3 months after operation,the effective rate was 98.44%,40 effective cases in the control group,the effective rate was 100.00%,and there was no significant difference between the two groups (χ2 =0.185,P >0.05).There were 62 effective cases in the observation group in 6 months after operation,the effective rate was 96.88%,40 effective cases in the control group,the effective rate was 100.00%,and there was no significant difference between the two groups (χ2 =0.306,P >0.05).There were 59 effective cases in the observation group in 12 months after operation,the effective rate was 92.19%,38 effective cases in the control group,the effective rate 95.00%,and there was no significant difference between the two groups (χ2 =0.227,P >0.05).The mean operation time in the observation group was (10.8 ±2.7)min,while (0.1 ± 9.6)min in the control group,the mean operation time in the observation group was shorter than that in the control group(t =18.074,P <0.05).The mean hospitalization in the observation group was (2.5 ±0.3)days,while (6.3 ± 1.4)days in the control group,the mean hospitalization in the observation group was shorter than that in the control group(t =3.171,P <0.05).The mean hospital expenses in the observation group was (1467.1 ±26.7)yuan,while (1971.6 ±59.1)yuan in the control group,the mean hospital expenses in the observation group was less than that in the control group(t =39.482,P <0.05).Conclusion The recent therapeutic effects of lacrimal ducts retrograde intubation and dacryocystorhinostomy in treating chronic dacryocystitis were same,and it was safer,lower operative difficult,less treatment expenses to applying lacrimal ducts retrograde intubation.It was worthy of clinical application.

AlM:To explore the efficacy and safety of mitomycin C used in trabeculectomy by analyzing intraocular pressure and blood flow.METHODS:A total of 103 patients with glaucoma were divided into 2 groups randomly, and all patients were treated with trabeculectomy, while patients in the observation group were given mitomycin C extra. At 6~12mo follow-up were completed after operation, and the clinical efficacy, complications and hemodynamic characteristics of central retinal artery were compared between groups.RESULTS: The clinical efficacy of the observation group was higher than that of the controls (P<0. 05). There was no significant difference in complication rate between groups (P>0. 05), but the complication type was differentiate to some extent. Low intraocular pressure and photophobia symptoms occurred mostly in the observation group, while cicatricial obstruction occurred mostly in the controls. Before treatment, there was no significant difference in hemodynamic characteristics between groups (P>0. 05). One month after treatment, the peak systolic velocity ( PSV) and end diastolic velocity ( EDV ) of the observation group were obviously lower, while resistance index ( Rl ) and pulsatility index ( Pl ) were higher than those of the controls, the difference was statistically significant ( P<0. 05). Six months after treatment, the PSV and EDV of the observation group were obviously higher, while Rl and Pl were lower than those of the controls, the difference was statistically significant (P<0. 05).CONCLUSlON:Mitomycin C has a short-term harmful effect on glaucoma patients after trabeculectomy, but its long-term effect is safe and reliable.

Objective To investigate the clinical data of Mycoplasma pneumoniae pneumonia(MPP)compli-cated with embolism in children,and to improve the understanding of the clinical features,diagnosis and treatment of the disease.Methods Six cases of MPP complicated with embolization,who were treated at Nanjing Children′s Hospital Affiliated to Nanjing Medical University from January 201 0 to June 201 5,were analyzed retrospectively.Results The ages of 6 cases ranged from 3 years and 3 months old to 1 3 years and 1 0 months old,and 3 cases were boys,3 cases were girls.All of 6 patients had high fever,positive anti -Mycoplasma IgM antibody (≥1 160)and sputum fluores-cence quantitative -Mycoplasma pneumonia (FQ -MP DNA),and all the chest imaging was consistent with pneumonia. Among 6 patients,4 cases complicated with liver function damage,4 cases had D -dimer rise,5 cases of erythrocyte sedi-mentation rate increased at different degree,while pleural effusion or pleuritis was found in 5 cases.The region of embo-lism in the cases included left renal artery in 1 case,the left popliteal artery in 1 case,the right middle cerebral artery em-bolism combined with cerebral infarction in 1 case,the right subclavian vein embolism combined with right upper extremi-ty embolism in 1 case,the basilar artery and bilateral posterior cerebral artery embolism combined with cerebral infarction in 1 case,and the other case involved the right pulmonary embolism.One case received thrombus dislodgment operation, and all of 6 cases were given the treatment including anti -infection,anticoagulation and low dose of glucocorticoid the-rapy,among whom 1 case died of cerebral hernia,and the other 5 cases improved.Conclusions MPP is often complicated with hypercoagulative state and potentialized to thrombosis,and thrombus may occur in vessels of whole body organs,and cerebral infarction had poor prognosis.Consequently,doctors should be aware of the potential risk factors for thrombosis. Early diagnosis and prompt anticoagulation and thrombolytic therapy could reduce mortality and disability rate.

This paper describes the measuring principle and algorithm of atherogenic index with oscillometric model. The algorithm proves effective and reliable through analyses of many cases and lots of clinical tests, which has been applied to the development of Lab-VIEW-based software for clinical use. Both patients and doctors can turn to this software for the information of angiosclerosis.

Objective To test a snapback primer for the identification of Legionella and Legionella pneumophila ( L.pneumophila) strains in a one-step real-time PCR assay.Methods A novel primer was designed with a pair of genus-specific primers of Legionella strains.The species-specific probe sequences of L.pneumophila strains were linked at the 5′end of the reverse primer.The sensitivity and specificity of the novel PCR assay were tested with 43 types of Legionella and non-Legionella strains.The established PCR as-say was used to identify 186 wild Legionella strains isolated from 11 provinces of China and 15 environmental water samples.Results The amplicon melting peak of Legionella strains was detected at 85-86℃.The snapback melting peak of L.pneumophila was detected at 71℃.No melting peak of non-Legionella strains was detected.The sensitivity of the standard strains and simulated water samples were 1 ng/μl DNA tem-plates and (1×103-1×104 )/ml, respectively.186 Legionella strains and 44 L.pneumophila strains isolated from environmental water samples were successfully identified with the snapback primer.Twealve Legionella strains and 4 L.pneumophila strains were identified from 15 environmental water samples with the snapback primer as compared with 8 Legionella strains identified with the culture method.Conclusion The snapback primer mediated one-step PCR assay could be used for the identification of Legionella and L.pneumophila strains with the advantages of high specificity and sensitivity.
